<p><img alt="Me, giving the talk" src="../../../../../wp-content/uploads/2018/coventry.jpg"></p>
<h2>In the beginning there was the LMS</h2>
<p>Learning Management Systems appeared on the market around the beginning of 2000.</p>
<p>Since then they have been the foundation of the modern education sector, ranging from the basic functionalities of activity tracking, grades and analytics for the students (and in some cases the parents) to complex environments for remote education or even experimental pedagogies (e.g. <a href="https://fare.polito.it">FARE</a> that provides hospitalized students means to access the physical class and labs).</p>
<p>In the last five years commercial LMS reduced the pace of their progress, while providing better accessibility and decentralization.</p>
<p>The core of their principle hasn't changed. In this talk I am going to highlight their problems and outline a vision for a different approach that is supported by modern technologies.</p>
<h3>The problem of traditional LMS</h3>
<p>The design of a Learning Management System is based mainly around closed structures, such as very strict roles management and access management.</p>
<p>In a scenario where a professor might want to bring a domain expert during classes and online, a traditional LMS doesn't provide any kind of facilities for things such a role (in terms of login rights, rights towards other users, moderation capabilities).</p>
<p>There are many corner cases that lack a general method that allows users to expand the features of an LMS, especially when an institution lacks the technical means to bring development to such platforms.</p>
<p>Moreover, traditional LMS are highly gerarchic and foster an epistemology of "possession": learners are defined by the content that they "possess", the course they subscribed to, the material they downloaded. The educator is forced to be an authoritative source of knowledge that needs to direct the activity of the learners by having students pull the knowledge through an online portal. The flow is unidirectional and content centric.</p>
<p>In my experience instructors produce delivery-centered pedagogies because LMS lacks the flexibility to be adapted to learners, especially when they are used by a variety of instructors (e.g.: all of the professors of a UNI). While this model better reflects the traditional classroom I would argue that modern users are not used to this kind of dynamics in modern online communities.</p>
<p>You can learn more about the friction in the usage of traditional LMS in the following papers:</p>
<ul>
<li>
<p>Rubin, Fernandes, Avgerinou, &amp; Moore, 2010</p>
</li>
<li>
<p>Naveh, Tubin, &amp; Pliskin, 2010</p>
</li>
<li>
<p>Parry, 2009; Sanchez-Franco, 2010</p>
</li>
<li>
<p>Beebe et al., 2010</p>
</li>
</ul>
<h3>Hacking Education with Digital Pedagogies</h3>
<p>What happens when education gets "hacked" and transitions in the digital world?
This is what we envision within the realms of the EduHack project:</p>
<ul>
<li>
<p>"Content to consume" becomes "content to consume to produce content": learners become knowledge builders because producing intellectual outputs is the logical continuation to learning.</p>
</li>
<li>
<p>The environment goes from content centric to learner centric: teachers must be comfortable with the fluidity of such new roles.</p>
</li>
<li>
<p>The distribution of information goes from knowledge-push to knowledge-pull: learners actively seek out educational material and gets rewarded.</p>
</li>
</ul>
<p>In the academia the closest study in this direction has been:
eLearning 2 0 and new literacies are social practices lagging behind, W.-Y. Lim et al.</p>
<h4>What do we gain with OSNs</h4>
<p>In the Web 2.0 landscape and in particular for younger generations, Online Social Networks (OSNs) have strong potential for building and mantaining strong connections and create an informal learning environment that collects and puts into actions the ideas that I have described.
I wont rehash widely known statistics, but it must be said that nowadays OSNs, in particular Facebook, Youtube and Twitter have a high rate of penetration towards students of upper secondary and post secondary education. For younger students OSNs are their primary means of communication while dominating their usage of the internet overall.</p>

</li>
</ul>
<h3>Case studies: Facebook as an alternative LMS</h3>
<p>Different case studies analyzed the possible uses of Facebook as a social LMS.
The following is a list of the positive and negative results of such studies grouped by User Experience Design (UX), Behavior of the users and Quantitative Participation.</p>
<h5>UX</h5>
<p>Advantages:</p>
<ol>
<li>
<p>Photos and discussions are presented better than traditional LMS.</p>
</li>
<li>
<p>User's walls, private messages and comments are considered just communication tools.</p>
</li>
<li>
<p>Users reported that the technologies used for sharing class related material was familiar.</p>
</li>
<li>
<p>Educators reported that Facebook was useful to answer questions in bulk.</p>
</li>
<li>
<p>Educators reported that given the capabilities above, they saved a lot of time that otherwise would have been spent dealing with class related communications and questions.</p>
</li>
</ol>
<p>Disadvantages:</p>
<ol>
<li>
<p>Users where skeptical in writing long essays.</p>
</li>
<li>
<p>Friction when used as a formal learning platform.</p>
</li>
<li>
<p>Private platforms have issues related to accessibilities and language. Communication was done in english even if that wasn't the case before;</p>
</li>
<li>
<p>Facebook doesn't support a wiki system.</p>
</li>
<li>
<p>There are no tools for group management.</p>
</li>
<li>
<p>There are no tools for sending bulk messages and group notifications.</p>
</li>
<li>
<p>No capabilities for deletion and archival of material.</p>
</li>
<li>
<p>No support for common multimedia (such as powerpoint slides or pdf).</p>
</li>
<li>
<p>Maximum characters limit for posts.</p>
</li>
</ol>
<h5>Behavior of the users</h5>
<p>Advantages:</p>
<ol>
<li>
<p>Users reached to older students and befriended them.</p>
</li>
<li>
<p>Users reported that they felt less pressure online.</p>
</li>
<li>
<p>Educators found that boldlier students asked more questions because of absense of face to face shyness.</p>
</li>
<li>
<p>Students help each other in answering questions</p>
</li>
<li>
<p>Six people from prior classes idependently requested to join the group</p>
</li>
<li>
<p>Constant and more accurate feedback for teachers</p>
</li>
<li>
<p>Constant communication for teachers</p>
</li>
<li>
<p>They got to know classmates better</p>
</li>
<li>
<p>In heavily moderated OSNs, few users find disappropriate contents.</p>
</li>
<li>
<p>In a comparison Facebook's discussion were more numerous than Moodle's discussions even when people were not allowed to be friends</p>
</li>
</ol>
<p>Disadvantages:</p>
<ol>
<li>
<p>Addiction</p>
</li>
<li>
<p>Students reported difficulties to get used to the new online persona.</p>
</li>
<li>
<p>Miscommunication: many prefer face to face interaction to express views. This maybe because they are used to it in traditional classrooms.</p>
</li>
<li>
<p>Some people say that they don't feel safe on FB (this is even more common when interviewing master students).</p>
</li>
<li>
<p>Some students worry that their personal life could be discovered and misjudged by tutors.</p>
</li>
<li>
<p>Students avoided to befriend educators and lecturers in order to hide their private lives.</p>
</li>
<li>
<p>During the research period, no student befriended the interviewed lecturers.</p>
</li>
<li>
<p>Students did not accept friend requests from lecturers.</p>
</li>
</ol>
<h5>Quantitative Participation</h5>
<p>Advantages:</p>
<ol>
<li>
<p>Overall the students are more responsive to issues and questions raised in classes.</p>
</li>
<li>
<p>There is a higher number of ongoing discussions in any period.</p>
</li>
<li>
<p>Users log to Facebook for class related activities also during vacations (while the university LMS was almost not used).</p>
</li>
<li>
<p>Very active participation: more than 90% of the students used Facebook outside of classes for study related activities.</p>
</li>
<li>
<p>Improved discussion outside of classes.</p>
</li>
<li>
<p>Students post class related material.</p>
</li>
<li>
<p>Creation of many User Generated Content.</p>
</li>
</ol>
<p>There are no relevant reported challenges regarding participation and usage patterns.</p>
<h3>Where do we go from here?</h3>
<p>I want to highlight some other threats that an OSN such as Facebook poses to the Open Web.</p>
<ul>
<li>
<p>The issue of privacy: forcing students to use a service that mines and sells their data is <strong>unethical</strong>.</p>
</li>
<li>
<p>Identity pollution: the open web is based on the principle of pseudoanonimity, users should be capable of build a prism of different online identity for different communities and environments.</p>
</li>
<li>
<p>Studies report Facebook as more appropriate for younger students, but younger people have higher rates of addiction to OSNs as well.</p>
</li>
<li>
<p>Addicted OSNs users have a lower GPA.</p>
</li>
<li>
<p>20% of college students reported being stalked on OSNs.</p>
</li>
</ul>
<p>While the reported results about learners and educators participation in the usage of OSNs as LMS is astounding, forcing students to signup and give away their sensible data to private services is debatable and could be considered unethical.</p>
<h2>The EduHack model</h2>
<p>We need to develop a new LMS that is respectful of the Open Web standards without providing any friction to the users.</p>
<p>For this reasons, as part of the EduHack Project, we are developing the EduHack Knowledge Sharing Platform.</p>
<p>The EduHack Knowledge Sharing Platform was born around the assumption that many of the advantages in terms of user engagement and group dynamics</p>
<p>provided by OSNs could be replicated by adopting their widely known design patterns and mimicing closely the UX.</p>
<p>At the core of the platform there are the founding principles of the Open Web.</p>
<p>For this reason no data is collected of mined. Users are provided with an account that could be separated from their different online persona.</p>
<h5>A platform for collaborative learning</h5>
<p>The EduHack Knowledge Sharing Platform is divided into two parts.</p>
<p>The personal area is user centric and provides a window into the activities of the user in the form of multimedia blogposts.</p>
<p>The user can create and manage different roles for external editors to his private area. By default no other user is allowed to post a "story" in his personal area, but other users can be added as team members and can manage group works in different blogs.</p>
<p>Learners are expected to elaborate and remix what they learned (e.g. from online classes or MOOCs).</p>
<p>The public area is modelled after the UX of Reddit and it is divided into diffent sections (e.g.: mathematics, IT, discrete phisics, etc...), each providing a wiki.</p>
<p>Learners can subscribe to different sections or different users and be notified of new content or interactions.</p>
<p>Every user is allowed to post a link, an essay or any other widely adopted multimedia artifact to any section. Every user can positively vote and comment every post made. Comments can be positively voted as well.</p>
<p>Comments and content can be ordered by a custom algorithm (Wilson score interval) or chronologically.</p>
<p>Educators have a custom flair, can create new sections and moderate them. Moderation consists in changing links, removing posts or comments. Vote cannot be altered.</p>
<h3>Conclusions</h3>
<p>The EduHack Knowledge Sharing Platform is an ongoing effort to evolve LMS and augment them with social features and modern group dynamics.</p>
<p>The UX is modeled after a widely used social network without sacrificing consolidated approaches from traditional LMS.</p>
<p>We want to provide with this model an ethically sound framework for user centric, knowledge-pull pedagogies.</p>

This is the revised transcript of my [talk](http://conf.owlteh.org/contributions/published/elearning-in-the-age-of-social-networks-the-eduhack-model/) at the [OWLTEH Conference 2018](https://www.conf.owlteh.org/) at the Coventry University.
![Me, giving the talk](/wp-content/uploads/2018/coventry.jpg)
# In the beginning there was the LMS
Learning Management Systems appeared on the market around the beginning of 2000.
Since then they have been the foundation of the modern education sector, ranging from the basic functionalities of activity tracking, grades and analytics for the students (and in some cases the parents) to complex environments for remote education or even experimental pedagogies (e.g. [FARE](https://fare.polito.it) that provides hospitalized students means to access the physical class and labs).
In the last five years commercial LMS reduced the pace of their progress, while providing better accessibility and decentralization.
The core of their principle hasn't changed. In this talk I am going to highlight their problems and outline a vision for a different approach that is supported by modern technologies.
## The problem of traditional LMS
The design of a Learning Management System is based mainly around closed structures, such as very strict roles management and access management.
In a scenario where a professor might want to bring a domain expert during classes and online, a traditional LMS doesn't provide any kind of facilities for things such a role (in terms of login rights, rights towards other users, moderation capabilities).
There are many corner cases that lack a general method that allows users to expand the features of an LMS, especially when an institution lacks the technical means to bring development to such platforms.
Moreover, traditional LMS are highly gerarchic and foster an epistemology of "possession": learners are defined by the content that they "possess", the course they subscribed to, the material they downloaded. The educator is forced to be an authoritative source of knowledge that needs to direct the activity of the learners by having students pull the knowledge through an online portal. The flow is unidirectional and content centric.
In my experience instructors produce delivery-centered pedagogies because LMS lacks the flexibility to be adapted to learners, especially when they are used by a variety of instructors (e.g.: all of the professors of a UNI). While this model better reflects the traditional classroom I would argue that modern users are not used to this kind of dynamics in modern online communities.
You can learn more about the friction in the usage of traditional LMS in the following papers:
* Rubin, Fernandes, Avgerinou, & Moore, 2010
* Naveh, Tubin, & Pliskin, 2010
* Parry, 2009; Sanchez-Franco, 2010
* Beebe et al., 2010
## Hacking Education with Digital Pedagogies
What happens when education gets "hacked" and transitions in the digital world?
This is what we envision within the realms of the EduHack project:
* "Content to consume" becomes "content to consume to produce content": learners become knowledge builders because producing intellectual outputs is the logical continuation to learning.
* The environment goes from content centric to learner centric: teachers must be comfortable with the fluidity of such new roles.
* The distribution of information goes from knowledge-push to knowledge-pull: learners actively seek out educational material and gets rewarded.
In the academia the closest study in this direction has been:
eLearning 2 0 and new literacies are social practices lagging behind, W.-Y. Lim et al.
### What do we gain with OSNs
In the Web 2.0 landscape and in particular for younger generations, Online Social Networks (OSNs) have strong potential for building and mantaining strong connections and create an informal learning environment that collects and puts into actions the ideas that I have described.
I wont rehash widely known statistics, but it must be said that nowadays OSNs, in particular Facebook, Youtube and Twitter have a high rate of penetration towards students of upper secondary and post secondary education. For younger students OSNs are their primary means of communication while dominating their usage of the internet overall.
* Using Social Networks Technology to Enhance Learning in Higher Education: a Case Study using Facebook.
* Web-Based Learning Platforms integratins Social Networking for Design Educations at High Schols in China.
* Using online social networking for teaching and learning: Facebook use at the University of Cape Town.
## Case studies: Facebook as an alternative LMS
Different case studies analyzed the possible uses of Facebook as a social LMS.
The following is a list of the positive and negative results of such studies grouped by User Experience Design (UX), Behavior of the users and Quantitative Participation.
#### UX
Advantages:
1. Photos and discussions are presented better than traditional LMS.
2. User's walls, private messages and comments are considered just communication tools.
3. Users reported that the technologies used for sharing class related material was familiar.
4. Educators reported that Facebook was useful to answer questions in bulk.
5. Educators reported that given the capabilities above, they saved a lot of time that otherwise would have been spent dealing with class related communications and questions.
Disadvantages:
1. Users where skeptical in writing long essays.
2. Friction when used as a formal learning platform.
3. Private platforms have issues related to accessibilities and language. Communication was done in english even if that wasn't the case before;
3. Facebook doesn't support a wiki system.
4. There are no tools for group management.
5. There are no tools for sending bulk messages and group notifications.
6. No capabilities for deletion and archival of material.
7. No support for common multimedia (such as powerpoint slides or pdf).
8. Maximum characters limit for posts.
#### Behavior of the users
Advantages:
1. Users reached to older students and befriended them.
2. Users reported that they felt less pressure online.
3. Educators found that boldlier students asked more questions because of absense of face to face shyness.
4. Students help each other in answering questions
5. Six people from prior classes idependently requested to join the group
6. Constant and more accurate feedback for teachers
7. Constant communication for teachers
8. They got to know classmates better
9. In heavily moderated OSNs, few users find disappropriate contents.
10. In a comparison Facebook's discussion were more numerous than Moodle's discussions even when people were not allowed to be friends
Disadvantages:
1. Addiction
2. Students reported difficulties to get used to the new online persona.
3. Miscommunication: many prefer face to face interaction to express views. This maybe because they are used to it in traditional classrooms.
4. Some people say that they don't feel safe on FB (this is even more common when interviewing master students).
5. Some students worry that their personal life could be discovered and misjudged by tutors.
6. Students avoided to befriend educators and lecturers in order to hide their private lives.
7. During the research period, no student befriended the interviewed lecturers.
8. Students did not accept friend requests from lecturers.
#### Quantitative Participation
Advantages:
1. Overall the students are more responsive to issues and questions raised in classes.
2. There is a higher number of ongoing discussions in any period.
3. Users log to Facebook for class related activities also during vacations (while the university LMS was almost not used).
4. Very active participation: more than 90% of the students used Facebook outside of classes for study related activities.
5. Improved discussion outside of classes.
6. Students post class related material.
7. Creation of many User Generated Content.
There are no relevant reported challenges regarding participation and usage patterns.
## Where do we go from here?
I want to highlight some other threats that an OSN such as Facebook poses to the Open Web.
* The issue of privacy: forcing students to use a service that mines and sells their data is **unethical**.
* Identity pollution: the open web is based on the principle of pseudoanonimity, users should be capable of build a prism of different online identity for different communities and environments.
* Studies report Facebook as more appropriate for younger students, but younger people have higher rates of addiction to OSNs as well.
* Addicted OSNs users have a lower GPA.
* 20% of college students reported being stalked on OSNs.
While the reported results about learners and educators participation in the usage of OSNs as LMS is astounding, forcing students to signup and give away their sensible data to private services is debatable and could be considered unethical.
# The EduHack model
We need to develop a new LMS that is respectful of the Open Web standards without providing any friction to the users.
For this reasons, as part of the EduHack Project, we are developing the EduHack Knowledge Sharing Platform.
The EduHack Knowledge Sharing Platform was born around the assumption that many of the advantages in terms of user engagement and group dynamics
provided by OSNs could be replicated by adopting their widely known design patterns and mimicing closely the UX.
At the core of the platform there are the founding principles of the Open Web.
For this reason no data is collected of mined. Users are provided with an account that could be separated from their different online persona.
#### A platform for collaborative learning
The EduHack Knowledge Sharing Platform is divided into two parts.
The personal area is user centric and provides a window into the activities of the user in the form of multimedia blogposts.
The user can create and manage different roles for external editors to his private area. By default no other user is allowed to post a "story" in his personal area, but other users can be added as team members and can manage group works in different blogs.
Learners are expected to elaborate and remix what they learned (e.g. from online classes or MOOCs).
The public area is modelled after the UX of Reddit and it is divided into diffent sections (e.g.: mathematics, IT, discrete phisics, etc...), each providing a wiki.
Learners can subscribe to different sections or different users and be notified of new content or interactions.
Every user is allowed to post a link, an essay or any other widely adopted multimedia artifact to any section. Every user can positively vote and comment every post made. Comments can be positively voted as well.
Comments and content can be ordered by a custom algorithm (Wilson score interval) or chronologically.
Educators have a custom flair, can create new sections and moderate them. Moderation consists in changing links, removing posts or comments. Vote cannot be altered.
## Conclusions
The EduHack Knowledge Sharing Platform is an ongoing effort to evolve LMS and augment them with social features and modern group dynamics.
The UX is modeled after a widely used social network without sacrificing consolidated approaches from traditional LMS.
We want to provide with this model an ethically sound framework for user centric, knowledge-pull pedagogies.

Quest'anno molto del mio tempo passato al pc e\` stato investito per D e la sua community.
I miei sforzi nell'imparare questo linguaggio sono confluiti nella partecipazione al [SAOC](https://dlang.org/blog/symmetry-autumn-of-code) con il mio amico e collega [Francesco Galla\`](https://fragal.eu).
Accompagnero\` Francesco all'edizione del 2019 della [DConf](https://dconf.org/2019/index.html) che si terra\` dall'otto all'undici marzo a Londra.
See you there!

<p>Questo articolo è stato originalmente scritto per il <a href="https://tldr.italyinformatica.org">blog</a> di <a href="https://reddit.com/r/italyinformatica">r/italyinformatica</a>.</p>
<p>Negli ultimi anni abbiamo assistito all'ascesa di un gran numero di linguaggi di programmazione, in particolare <a href="https://golang.rg">Go</a> (2009), <a href="https://www.rust-lang.org/en-US/">Rust</a> (2010), <a href="https://kotlinlang.org/">Kotlin</a> (2011), <a href="https://elixir-lang.org/">Elixir</a> (2011), <a href="https://crystal-lang.org/">Crystal</a> (2014), <a href="https://www.ponylang.or">Pony</a> (2014).</p>
<p>Questa esplosione di nuovi linguaggi è dovuta, fra le molte motivazioni, alla necessità di adottare paradigmi di programmazione non immediatamente recenti come cittadini di primo tipo.</p>
<p>Rispetto ai più maturi C, C++ o Java, Python o Ruby questi linguaggi offrono "out of the box" supporto per:</p>
<ul>
<li>una visione moderna delle concorrenze (le goroutines di Go o il modello ad attori di Pony ed Elixir)</li>
<li>Memory safeness, in particolare:<ul>
<li>assenza di NULL (Pony, Rust, Kotlin)</li>
<li>gestione automatica della memoria, il cosiddetto <a href="https://en.wikipedia.org/wiki/Garbage_collection_(computer_science)%20(o%20%5BReference%20Counting%5D(https://en.wikipedia.org/wiki/Reference_counting)%20per%20Rust">Garbage Collector</a>
</li>
<li>assenza di puntatori</li>
<li>assenza di deadlocks</li>
</ul>
</li>
<li>Supporto ad HTTP nella standard library</li>
<li>Management delle dipendenze (ad eccezione di Kotlin)</li>
<li>Namespaces</li>
</ul>
<p>Chiaramente nessuno di questi linguaggi è oggettivamente superiore agli altri, sono tutti <a href="https://en.wikipedia.org/wiki/Turing_completeness">turing completi</a> e la scelta del programmatore ricade su motivazioni del tutto personali (stile, programmazione ad oggetti, familiarità con altri linguaggi).</p>
<h3>Un pò di contesto</h3>
<p>Ho scritto la mie prime due righe di codice nel 2013 per il corso di Computer Science del Politecnico di Torino.</p>
<p>Per mia fortuna, al Politecnico le cose si muovono ancora lentamente e ci hanno fatto usare C per tutta la durata della triennale. Si è aggiunto un corso di principi della programmazione ad oggetti al terzo anno, in Java.</p>
<p>Personalmente ho imparato durante l'estate di quel primo anno le basi di C++ e Python poco dopo.</p>
<p>Sono stati con i miei primi <a href="https://github.com/framecca">progetti</a> che ho capito che non si può avere un buon linguaggio senza un buon tooling ed una community vivace e soprattutto tanta, tanta documentazione. Per questo, per molto tempo C è stata la mia prima scelta, dato che il mio target è sempre Linux.</p>
<h3>Gli obbiettivi prima del linguaggio</h3>
<p>Questo post vuole essere una raccolta più o meno organizzata delle motivazioni per cui mi sono dovuto muovere oltre la frontiera di C nel mio ultimo progetto, ovvero un backend per la raccolta e presentazione di pubblicazione di ricerca e materiale didattico per più di 80 centri di ricerca.</p>
<p>Per il Centro <a href="http://nexa.polito.it/">Nexa</a> del Politecnico di Torino mi sono ritrovato per la prima volta responsabile del codice che dovevo scrivere e dell'uso che se ne sarebbe fatto.</p>
<p>Ho dovuto tenere in considerazione, oltre chiaramente alla funzionalità della piattaforma, in ordine di priorità:</p>
<ol>
<li>Sicurezza</li>
<li>Performance e scalabilità</li>
<li>Separazione dal frontend</li>
<li>Facilità di deploy in un server che non controllo</li>
</ol>
<p>Fortunatamente non mi è stata imposta nessuna limitazione sulla scelta del linguaggio, altrimenti Python sarebbe stato la scelta più adeguata se avessi dovuto tener conto anche di altri programmatori.</p>
<h3>Benvenuto D</h3>
<p>La mia scelta è caduta su <a href="https://dlang.org">D</a>.</p>
<p>Voglio provare ad affrontare ad uno ad uno i motivi di questa scelta magari inusuale.</p>
<h5>Sicurezza</h5>
<p>Nessuno vuole davvero vantarsi di usare un backend scritto in C/C++. Il <a href="https://en.wikipedia.org/wiki/Buffer_overflow">buffer overflow</a> può essere considerato il bug più comune e ci sono <a href="https://techaeris.com/2017/09/27/buzz-fuzzing-find-uncommon-vulnerability/">situazioni</a> in cui non appaiono affatto in maniera ovvia.</p>
<p>Inoltre per un applicativo distribuito il Garbage Collector è la scelta più performante, <a href="https://www.usenix.org/node/189882">specialmente se coordinato fra le varie istanze</a>.</p>
<p>D offre questo di design, e benchè il suo GC sia frutto di numerose <a href="https://www.quora.com/Which-language-has-the-brightest-future-in-replacement-of-C-between-D-Go-and-Rust-And-Why/answer/Andrei-Alexandrescu">discussioni</a>, offre in maniera del tutto innovativa, robustezza e <a href="http://www.walterbright.com/gonewild.pdf">sicurezza</a>.</p>
<p>In particolare, D presenta:</p>
<ul>
<li>Array che sono slices (o ranges) ma non puntatori (e neanche oggetti)</li>
<li>Bound checking durante la fase di compilazione.</li>
<li>Inizializzazione automatica delle variabili.</li>
<li>Safe Casting (chiaramente come eredità di C++).</li>
<li>Restricted pointers: si può passare una funzione per referenza dichiarandola <code>ref</code>, ma solo quando passata come parametro o di ritorno. Inoltre non c'è nessuna pointer arithmetic.</li>
<li>
<a href="https://en.wikipedia.org/wiki/Resource_acquisition_is_initialization">RAII</a>, ovvero l'acquisizione delle risorse equivale alla loro assegnazione e Scopes: le variabili hanno una lifetime limitata allo scope di dichiarazione. Nessun dangling pointer come in C.</li>
<li>Strutture immutabili: come nelle specifiche di molti linguaggi funzionali, si può dichiarare una variabile come <code>immutable</code> e quindi può essere facilmente condivisa fra threads.</li>
<li>@safe, @trusted: le specifiche del linguaggio permettono di annotare delle funzioni come sicure o affidabili affinchè il compilatore controlli che non gestiscano puntatori (ad esempio interfacciandosi con C) ed utilizzino il subset "sicuro" del linguaggio (maggiori dettagli in seguito).</li>
<li>funzioni pure: le funzioni inoltre possono essere dichiarate pure, prive di effetti collaterali e sempre <a href="https://en.wikipedia.org/wiki/Reentrancy_(computing)">rientranti</a>. Questo permette di evitare <a href="https://en.wikipedia.org/wiki/Deadlock">deadlocks</a> e un controllo totale sul risultato delle funzioni.</li>
</ul>
<h5>Performance</h5>
<p>Ci sono moltissime soluzioni per scrivere un applicativo che si interfaccia con il web, ma hanno tutte la loro origine nel famoso <a href="http://www.kegel.com/c10k.html">C10K problem</a>.</p>
<p>Nel mio caso ho deciso di utilizzare un approccio <a href="https://stackoverflow.com/questions/10960998/how-different-async-programming-is-from-threads">asincrono</a> con coroutines (anche detti <a href="https://en.wikipedia.org/wiki/Green_threads">threads leggeri</a>).</p>
<p>Benchè D abbia <a href="https://dlang.org/library/core/thread/fiber.html">supporto nativo</a> alle coroutines, ho deciso di appoggiarmi al framework più comune per web dev in D: <a href="vibed.org">vibe.d</a>.</p>
<p>Ogni volta che Vibe accetta una richiesta dall'esterno ed esegue una funzione bloccante (che interrompe l'esecuzione del programma fino al ritorno della funzione), questa viene messa in una pool di azioni da eseguire e Vibe controlla periodicamente che almeno una di queste sia pronta a ritornare un risultato e continuare con l'esecuzione di questa.</p>
<p>Inoltre, benchè questo meccanismo funzioni interamente su un solo thread, è elementare coordinare una <a href="https://en.wikipedia.org/wiki/Thread_pool">thread pool</a> che distribuisa il carico fra i vari core che eseguono migliaia di threads leggeri concorrentemente.</p>
<h5>Contratti e Tests</h5>
<p>Non amo scrivere commenti sui programmi. Penso sia assolutamente necessario commentare il codice di librerie ma al di fuori di queste il codice (buon codice) dovrebbe essere autoesplicativo.</p>
<p>Inoltre, nelle mie recenti esperienze, il comportamento del programma era chiaro a partire dai tests.</p>
<p>In D questo concetto viene portato agli estremi applicando il <a href="https://en.wikipedia.org/wiki/Design_by_contract">"Design by Contract programming</a>.</p>
<p>Un contratto è la divisione di una funzione in:</p>
<ul>
<li>Precondizione, ovvero le condizioni che devono essersi verificate prima della chiamata della funzione;</li>
<li>Postcondizione, ovvero le condizioni che devono essere rispettate all'uscita della funzione (solitamente applicate al risultato);</li>
<li>Invarianti, ovvero le specifiche di una struttura dati che devono rimanere verificate in ogni funzione;</li>
<li>Corpo della funzione</li>
</ul>
<p>Un esempio:</p>
<pre class="code literal-block"><span></span>struct Clock {
short time;
invariant {
assert (time &gt; 0);
}
}
short addReturnTime(Clock c, short n)
in {
n &gt; 0;
}
body {
return c-&gt;time + t;
}
out (result){
result &gt; c-&gt;time;
}
unittest {
auto clock = Clock(60);
assert (addReturnTime(clock, 10) == 70);
}
</pre>
<p>Come si nota dall'esempio il supporto ai tests è built-in nel linguaggio e distanti solo una flag in fase di compilazione.</p>
<h5>Un approccio moderno alle concorrenze</h5>
<p>Il modello primitivo delle concorrenze in Posix è discutibilmente datato e prono ad errori per il programmatore.</p>
<p>D di default evita la condivisione di dati fra Threads.
Fra le varie motivazioni c'è il fatto che questo rifletta più realisticamente l'hardware, ma sicuramente l'obbiettivo finale è la riduzione di bug.</p>
<p>Non voglio dilungarmi nei dettagli di ogni singolo approccio, ma per completezza D offre out of the box i seguenti modelli:</p>
<ul>
<li>Message passing e <a href="http://dist-prog-book.com/chapter/3/message-passing.html">attori</a>, ovvero tutti i dati che vogliono essere condivisi fra thread sono incapsulati in <a href="https://en.wikipedia.org/wiki/Remote_procedure_call">RPC</a>;</li>
<li>Green threads, come nel mio caso;</li>
<li>Multi processing, ovvero <code>man 3 fork</code>
</li>
<li>TaskPools, ovvero future e promises di Python e Javascript;</li>
<li><a href="http://moss.csc.ncsu.edu/~mueller/cluster/ps3/SDK3.0/docs/accessibility/sdkpt/cbet_1simdvector.html">SIMD vectorization</a></li>
</ul>
<p>Andrei Alexandrescu, uno dei due creatori del linguaggio, dedica un intero capitolo alle concorrenze che potete leggere liberamente <a href="http://www.informit.com/articles/article.aspx?p=1609144">qui</a>.</p>
<h5>Assenza di dogmatismi</h5>
<p>Non potrei mai pensare di scrivere un linguaggio di programmazione senza mettere al secondo posto la semplicità.</p>
<p>Ma chiaramente ancora prima di discutere di semplicità la dobbiamo definire.</p>
<p>Go e Python sono due linguaggi semplici. Lo sono per la ridotta sintassi (Go in particolare) e perchè attraverso il loro dogmatismo costringono il programmatore ad adottare dei paradigmi di programmazione scelti dai designer di quel linguaggio. E` il motivo per cui in python non abbiamo delle vere lambda e per cui Go non ha le eccezioni.</p>
<p>In D il programmatore ha libertà piena di scelta. Oltre ad un paradigma di programmazione si può ridefinire la sintassi e evitare il Garbage Collector. Si può in ultimo disattivare tutte le feature del linguaggio che sono @safe e adottare uno stile molto più vicino al C/C++, con tanto di inline asm.</p>
<h3>Dove iniziare</h3>
<p>Non posso non concludere un post propagandistico senza indirizzare i più interessati alle prime risorse per imparare D.</p>
<p>Personalmente consiglio il <a href="http://www.informit.com/store/d-programming-language-9780321635365?w_ptgrevartcl=Concurrency+in+the+D+Programming+Language_1609144">libro</a> di Andrei che offre in particolare moltissimi dettagli sulle motivazioni del design di D. Non ho ancora letto un libro che affrontasse così chiaramente il design di linguaggi di programmazione e i vari compromessi fra performance, semplicità e complessità del compilatore.</p>
<p>Inoltre il sito della community offre due intro per chi proviene da <a href="https://dlang.org/ctod.html">C</a> e <a href="https://dlang.org/cpptod.html">C++</a>, oltre al classi <a href="https://tour.dlang.org/">tour</a>.</p>
<p>Inoltre la libreria standard, <a href="https://github.com/dlang/phobos">Phobos</a>, è talmente chiara che solitamente mi trovo a mio agio a consultare direttamente il codice piuttosto che la documentazione online.</p>

Questo articolo è stato originalmente scritto per il [blog](https://tldr.italyinformatica.org) di [r/italyinformatica](https://reddit.com/r/italyinformatica).
Negli ultimi anni abbiamo assistito all'ascesa di un gran numero di linguaggi di programmazione, in particolare [Go](https://golang.rg) (2009), [Rust](https://www.rust-lang.org/en-US/) (2010), [Kotlin](https://kotlinlang.org/) (2011), [Elixir](https://elixir-lang.org/) (2011), [Crystal](https://crystal-lang.org/) (2014), [Pony](https://www.ponylang.or) (2014).
Questa esplosione di nuovi linguaggi è dovuta, fra le molte motivazioni, alla necessità di adottare paradigmi di programmazione non immediatamente recenti come cittadini di primo tipo.
Rispetto ai più maturi C, C++ o Java, Python o Ruby questi linguaggi offrono "out of the box" supporto per:
- una visione moderna delle concorrenze (le goroutines di Go o il modello ad attori di Pony ed Elixir)
- Memory safeness, in particolare:
- assenza di NULL (Pony, Rust, Kotlin)
- gestione automatica della memoria, il cosiddetto [Garbage Collector](https://en.wikipedia.org/wiki/Garbage_collection_(computer_science) (o [Reference Counting](https://en.wikipedia.org/wiki/Reference_counting) per Rust)
- assenza di puntatori
- assenza di deadlocks
- Supporto ad HTTP nella standard library
- Management delle dipendenze (ad eccezione di Kotlin)
- Namespaces
Chiaramente nessuno di questi linguaggi è oggettivamente superiore agli altri, sono tutti [turing completi](https://en.wikipedia.org/wiki/Turing_completeness) e la scelta del programmatore ricade su motivazioni del tutto personali (stile, programmazione ad oggetti, familiarità con altri linguaggi).
## Un pò di contesto
Ho scritto la mie prime due righe di codice nel 2013 per il corso di Computer Science del Politecnico di Torino.
Per mia fortuna, al Politecnico le cose si muovono ancora lentamente e ci hanno fatto usare C per tutta la durata della triennale. Si è aggiunto un corso di principi della programmazione ad oggetti al terzo anno, in Java.
Personalmente ho imparato durante l'estate di quel primo anno le basi di C++ e Python poco dopo.
Sono stati con i miei primi [progetti](https://github.com/framecca) che ho capito che non si può avere un buon linguaggio senza un buon tooling ed una community vivace e soprattutto tanta, tanta documentazione. Per questo, per molto tempo C è stata la mia prima scelta, dato che il mio target è sempre Linux.
## Gli obbiettivi prima del linguaggio
Questo post vuole essere una raccolta più o meno organizzata delle motivazioni per cui mi sono dovuto muovere oltre la frontiera di C nel mio ultimo progetto, ovvero un backend per la raccolta e presentazione di pubblicazione di ricerca e materiale didattico per più di 80 centri di ricerca.
Per il Centro [Nexa](http://nexa.polito.it/) del Politecnico di Torino mi sono ritrovato per la prima volta responsabile del codice che dovevo scrivere e dell'uso che se ne sarebbe fatto.
Ho dovuto tenere in considerazione, oltre chiaramente alla funzionalità della piattaforma, in ordine di priorità:
1. Sicurezza
2. Performance e scalabilità
3. Separazione dal frontend
4. Facilità di deploy in un server che non controllo
Fortunatamente non mi è stata imposta nessuna limitazione sulla scelta del linguaggio, altrimenti Python sarebbe stato la scelta più adeguata se avessi dovuto tener conto anche di altri programmatori.
## Benvenuto D
La mia scelta è caduta su [D](https://dlang.org).
Voglio provare ad affrontare ad uno ad uno i motivi di questa scelta magari inusuale.
#### Sicurezza
Nessuno vuole davvero vantarsi di usare un backend scritto in C/C++. Il [buffer overflow](https://en.wikipedia.org/wiki/Buffer_overflow) può essere considerato il bug più comune e ci sono [situazioni](https://techaeris.com/2017/09/27/buzz-fuzzing-find-uncommon-vulnerability/) in cui non appaiono affatto in maniera ovvia.
Inoltre per un applicativo distribuito il Garbage Collector è la scelta più performante, [specialmente se coordinato fra le varie istanze](https://www.usenix.org/node/189882).
D offre questo di design, e benchè il suo GC sia frutto di numerose [discussioni](https://www.quora.com/Which-language-has-the-brightest-future-in-replacement-of-C-between-D-Go-and-Rust-And-Why/answer/Andrei-Alexandrescu), offre in maniera del tutto innovativa, robustezza e [sicurezza](http://www.walterbright.com/gonewild.pdf).
In particolare, D presenta:
- Array che sono slices (o ranges) ma non puntatori (e neanche oggetti)
- Bound checking durante la fase di compilazione.
- Inizializzazione automatica delle variabili.
- Safe Casting (chiaramente come eredità di C++).
- Restricted pointers: si può passare una funzione per referenza dichiarandola `ref`, ma solo quando passata come parametro o di ritorno. Inoltre non c'è nessuna pointer arithmetic.
- [RAII](https://en.wikipedia.org/wiki/Resource_acquisition_is_initialization), ovvero l'acquisizione delle risorse equivale alla loro assegnazione e Scopes: le variabili hanno una lifetime limitata allo scope di dichiarazione. Nessun dangling pointer come in C.
- Strutture immutabili: come nelle specifiche di molti linguaggi funzionali, si può dichiarare una variabile come `immutable` e quindi può essere facilmente condivisa fra threads.

- TaskPools, ovvero future e promises di Python e Javascript;
- [SIMD vectorization](http://moss.csc.ncsu.edu/~mueller/cluster/ps3/SDK3.0/docs/accessibility/sdkpt/cbet_1simdvector.html)
Andrei Alexandrescu, uno dei due creatori del linguaggio, dedica un intero capitolo alle concorrenze che potete leggere liberamente [qui](http://www.informit.com/articles/article.aspx?p=1609144).
#### Assenza di dogmatismi

## Dove iniziare
Non posso non concludere un post propagandistico senza indirizzare i più interessati alle prime risorse per imparare D.
Personalmente consiglio il [libro](http://www.informit.com/store/d-programming-language-9780321635365?w_ptgrevartcl=Concurrency+in+the+D+Programming+Language_1609144) di Andrei che offre in particolare moltissimi dettagli sulle motivazioni del design di D. Non ho ancora letto un libro che affrontasse così chiaramente il design di linguaggi di programmazione e i vari compromessi fra performance, semplicità e complessità del compilatore.
Inoltre il sito della community offre due intro per chi proviene da [C](https://dlang.org/ctod.html) e [C++](https://dlang.org/cpptod.html), oltre al classi [tour](https://tour.dlang.org/).
Inoltre la libreria standard, [Phobos](https://github.com/dlang/phobos), è talmente chiara che solitamente mi trovo a mio agio a consultare direttamente il codice piuttosto che la documentazione online.

<p>This is the revised transcript of my <a href="http://conf.owlteh.org/contributions/published/elearning-in-the-age-of-social-networks-the-eduhack-model/">talk</a> at the <a href="https://www.conf.owlteh.org/">OWLTEH Conference 2018</a> at the Coventry University.</p>

<h2>In the beginning there was the LMS</h2>
<p>Learning Management Systems appeared on the market around the beginning of 2000.</p>
<p>Since then they have been the foundation of the modern education sector, ranging from the basic functionalities of activity tracking, grades and analytics for the students (and in some cases the parents) to complex environments for remote education or even experimental pedagogies (e.g. <a href="https://fare.polito.it">FARE</a> that provides hospitalized students means to access the physical class and labs).</p>
<p>In the last five years commercial LMS reduced the pace of their progress, while providing better accessibility and decentralization.</p>
<p>The core of their principle hasn't changed. In this talk I am going to highlight their problems and outline a vision for a different approach that is supported by modern technologies.</p>
<h3>The problem of traditional LMS</h3>
<p>The design of a Learning Management System is based mainly around closed structures, such as very strict roles management and access management.</p>
<p>In a scenario where a professor might want to bring a domain expert during classes and online, a traditional LMS doesn't provide any kind of facilities for things such a role (in terms of login rights, rights towards other users, moderation capabilities).</p>
<p>There are many corner cases that lack a general method that allows users to expand the features of an LMS, especially when an institution lacks the technical means to bring development to such platforms.</p>
<p>Moreover, traditional LMS are highly gerarchic and foster an epistemology of "possession": learners are defined by the content that they "possess", the course they subscribed to, the material they downloaded. The educator is forced to be an authoritative source of knowledge that needs to direct the activity of the learners by having students pull the knowledge through an online portal. The flow is unidirectional and content centric.</p>
<p>In my experience instructors produce delivery-centered pedagogies because LMS lacks the flexibility to be adapted to learners, especially when they are used by a variety of instructors (e.g.: all of the professors of a UNI). While this model better reflects the traditional classroom I would argue that modern users are not used to this kind of dynamics in modern online communities.</p>
<p>You can learn more about the friction in the usage of traditional LMS in the following papers:</p>

</ul>
<h3>Hacking Education with Digital Pedagogies</h3>
<p>What happens when education gets "hacked" and transitions in the digital world?
This is what we envision within the realms of the EduHack project:</p>
<ul>
<li>
<p>"Content to consume" becomes "content to consume to produce content": learners become knowledge builders because producing intellectual outputs is the logical continuation to learning.</p>
</li>
<li>
<p>The environment goes from content centric to learner centric: teachers must be comfortable with the fluidity of such new roles.</p>
</li>
<li>
<p>The distribution of information goes from knowledge-push to knowledge-pull: learners actively seek out educational material and gets rewarded.</p>
</li>
</ul>
<p>In the academia the closest study in this direction has been:
eLearning 2 0 and new literacies are social practices lagging behind, W.-Y. Lim et al.</p>
<h4>What do we gain with OSNs</h4>
<p>In the Web 2.0 landscape and in particular for younger generations, Online Social Networks (OSNs) have strong potential for building and mantaining strong connections and create an informal learning environment that collects and puts into actions the ideas that I have described.
I wont rehash widely known statistics, but it must be said that nowadays OSNs, in particular Facebook, Youtube and Twitter have a high rate of penetration towards students of upper secondary and post secondary education. For younger students OSNs are their primary means of communication while dominating their usage of the internet overall.</p>

</li>
</ul>
<h3>Case studies: Facebook as an alternative LMS</h3>
<p>Different case studies analyzed the possible uses of Facebook as a social LMS.
The following is a list of the positive and negative results of such studies grouped by User Experience Design (UX), Behavior of the users and Quantitative Participation.</p>
<h5>UX</h5>
<p>Advantages:</p>
<ol>
<li>
<p>Photos and discussions are presented better than traditional LMS.</p>
</li>
<li>
<p>User's walls, private messages and comments are considered just communication tools.</p>
</li>
<li>
<p>Users reported that the technologies used for sharing class related material was familiar.</p>
</li>
<li>
<p>Educators reported that Facebook was useful to answer questions in bulk.</p>
</li>
<li>
<p>Educators reported that given the capabilities above, they saved a lot of time that otherwise would have been spent dealing with class related communications and questions.</p>
</li>
</ol>
<p>Disadvantages:</p>
<ol>
<li>
<p>Users where skeptical in writing long essays.</p>
</li>
<li>
<p>Friction when used as a formal learning platform.</p>
</li>
<li>
<p>Private platforms have issues related to accessibilities and language. Communication was done in english even if that wasn't the case before;</p>
</li>
<li>
<p>Facebook doesn't support a wiki system.</p>
</li>
<li>
<p>There are no tools for group management.</p>
</li>
<li>
<p>There are no tools for sending bulk messages and group notifications.</p>
</li>
<li>
<p>No capabilities for deletion and archival of material.</p>
</li>
<li>
<p>No support for common multimedia (such as powerpoint slides or pdf).</p>
</li>
<li>
<p>Maximum characters limit for posts.</p>
</li>
</ol>
<h5>Behavior of the users</h5>
<p>Advantages:</p>
<ol>
<li>
<p>Users reached to older students and befriended them.</p>
</li>
<li>
<p>Users reported that they felt less pressure online.</p>
</li>
<li>
<p>Educators found that boldlier students asked more questions because of absense of face to face shyness.</p>
</li>
<li>
<p>Students help each other in answering questions</p>
</li>
<li>
<p>Six people from prior classes idependently requested to join the group</p>
</li>
<li>
<p>Constant and more accurate feedback for teachers</p>
</li>
<li>
<p>Constant communication for teachers</p>
</li>
<li>
<p>They got to know classmates better</p>
</li>
<li>
<p>In heavily moderated OSNs, few users find disappropriate contents.</p>
</li>
<li>
<p>In a comparison Facebook's discussion were more numerous than Moodle's discussions even when people were not allowed to be friends</p>
</li>
</ol>
<p>Disadvantages:</p>
<ol>
<li>
<p>Addiction</p>
</li>
<li>
<p>Students reported difficulties to get used to the new online persona.</p>
</li>
<li>
<p>Miscommunication: many prefer face to face interaction to express views. This maybe because they are used to it in traditional classrooms.</p>
</li>
<li>
<p>Some people say that they don't feel safe on FB (this is even more common when interviewing master students).</p>
</li>
<li>
<p>Some students worry that their personal life could be discovered and misjudged by tutors.</p>
</li>
<li>
<p>Students avoided to befriend educators and lecturers in order to hide their private lives.</p>
</li>
<li>
<p>During the research period, no student befriended the interviewed lecturers.</p>
</li>
<li>
<p>Students did not accept friend requests from lecturers.</p>
</li>
</ol>
<h5>Quantitative Participation</h5>
<p>Advantages:</p>
<ol>
<li>
<p>Overall the students are more responsive to issues and questions raised in classes.</p>
</li>
<li>
<p>There is a higher number of ongoing discussions in any period.</p>
</li>
<li>
<p>Users log to Facebook for class related activities also during vacations (while the university LMS was almost not used).</p>
</li>
<li>
<p>Very active participation: more than 90% of the students used Facebook outside of classes for study related activities.</p>
</li>
<li>
<p>Improved discussion outside of classes.</p>
</li>
<li>
<p>Students post class related material.</p>
</li>
<li>
<p>Creation of many User Generated Content.</p>
</li>
</ol>
<p>There are no relevant reported challenges regarding participation and usage patterns.</p>
<h3>Where do we go from here?</h3>
<p>I want to highlight some other threats that an OSN such as Facebook poses to the Open Web.</p>
<ul>
<li>
<p>The issue of privacy: forcing students to use a service that mines and sells their data is <strong>unethical</strong>.</p>
</li>
<li>
<p>Identity pollution: the open web is based on the principle of pseudoanonimity, users should be capable of build a prism of different online identity for different communities and environments.</p>
</li>
<li>
<p>Studies report Facebook as more appropriate for younger students, but younger people have higher rates of addiction to OSNs as well.</p>
</li>
<li>
<p>Addicted OSNs users have a lower GPA.</p>
</li>
<li>
<p>20% of college students reported being stalked on OSNs.</p>
</li>
</ul>
<p>While the reported results about learners and educators participation in the usage of OSNs as LMS is astounding, forcing students to signup and give away their sensible data to private services is debatable and could be considered unethical.</p>
<h2>The EduHack model</h2>
<p>We need to develop a new LMS that is respectful of the Open Web standards without providing any friction to the users.</p>
<p>For this reasons, as part of the EduHack Project, we are developing the EduHack Knowledge Sharing Platform.</p>
<p>The EduHack Knowledge Sharing Platform was born around the assumption that many of the advantages in terms of user engagement and group dynamics</p>
<p>provided by OSNs could be replicated by adopting their widely known design patterns and mimicing closely the UX.</p>
<p>At the core of the platform there are the founding principles of the Open Web.</p>
<p>For this reason no data is collected of mined. Users are provided with an account that could be separated from their different online persona.</p>
<h5>A platform for collaborative learning</h5>
<p>The EduHack Knowledge Sharing Platform is divided into two parts.</p>
<p>The personal area is user centric and provides a window into the activities of the user in the form of multimedia blogposts.</p>
<p>The user can create and manage different roles for external editors to his private area. By default no other user is allowed to post a "story" in his personal area, but other users can be added as team members and can manage group works in different blogs.</p>
<p>Learners are expected to elaborate and remix what they learned (e.g. from online classes or MOOCs).</p>
<p>The public area is modelled after the UX of Reddit and it is divided into diffent sections (e.g.: mathematics, IT, discrete phisics, etc...), each providing a wiki.</p>
<p>Learners can subscribe to different sections or different users and be notified of new content or interactions.</p>
<p>Every user is allowed to post a link, an essay or any other widely adopted multimedia artifact to any section. Every user can positively vote and comment every post made. Comments can be positively voted as well.</p>
<p>Comments and content can be ordered by a custom algorithm (Wilson score interval) or chronologically.</p>
<p>Educators have a custom flair, can create new sections and moderate them. Moderation consists in changing links, removing posts or comments. Vote cannot be altered.</p>
<h3>Conclusions</h3>
<p>The EduHack Knowledge Sharing Platform is an ongoing effort to evolve LMS and augment them with social features and modern group dynamics.</p>
<p>The UX is modeled after a widely used social network without sacrificing consolidated approaches from traditional LMS.</p>
<p>We want to provide with this model an ethically sound framework for user centric, knowledge-pull pedagogies.</p>

This is the revised transcript of my [talk](http://conf.owlteh.org/contributions/published/elearning-in-the-age-of-social-networks-the-eduhack-model/) at the [OWLTEH Conference 2018](https://www.conf.owlteh.org/) at the Coventry University.
![Me, giving the talk](/wp-content/uploads/2018/coventry.jpg)
# In the beginning there was the LMS
Learning Management Systems appeared on the market around the beginning of 2000.
Since then they have been the foundation of the modern education sector, ranging from the basic functionalities of activity tracking, grades and analytics for the students (and in some cases the parents) to complex environments for remote education or even experimental pedagogies (e.g. [FARE](https://fare.polito.it) that provides hospitalized students means to access the physical class and labs).
In the last five years commercial LMS reduced the pace of their progress, while providing better accessibility and decentralization.
The core of their principle hasn't changed. In this talk I am going to highlight their problems and outline a vision for a different approach that is supported by modern technologies.
## The problem of traditional LMS
The design of a Learning Management System is based mainly around closed structures, such as very strict roles management and access management.
In a scenario where a professor might want to bring a domain expert during classes and online, a traditional LMS doesn't provide any kind of facilities for things such a role (in terms of login rights, rights towards other users, moderation capabilities).
There are many corner cases that lack a general method that allows users to expand the features of an LMS, especially when an institution lacks the technical means to bring development to such platforms.
Moreover, traditional LMS are highly gerarchic and foster an epistemology of "possession": learners are defined by the content that they "possess", the course they subscribed to, the material they downloaded. The educator is forced to be an authoritative source of knowledge that needs to direct the activity of the learners by having students pull the knowledge through an online portal. The flow is unidirectional and content centric.
In my experience instructors produce delivery-centered pedagogies because LMS lacks the flexibility to be adapted to learners, especially when they are used by a variety of instructors (e.g.: all of the professors of a UNI). While this model better reflects the traditional classroom I would argue that modern users are not used to this kind of dynamics in modern online communities.
You can learn more about the friction in the usage of traditional LMS in the following papers:
* Rubin, Fernandes, Avgerinou, & Moore, 2010
* Naveh, Tubin, & Pliskin, 2010
* Parry, 2009; Sanchez-Franco, 2010
* Beebe et al., 2010
## Hacking Education with Digital Pedagogies
What happens when education gets "hacked" and transitions in the digital world?
This is what we envision within the realms of the EduHack project:
* "Content to consume" becomes "content to consume to produce content": learners become knowledge builders because producing intellectual outputs is the logical continuation to learning.
* The environment goes from content centric to learner centric: teachers must be comfortable with the fluidity of such new roles.
* The distribution of information goes from knowledge-push to knowledge-pull: learners actively seek out educational material and gets rewarded.
In the academia the closest study in this direction has been:

4. Educators reported that Facebook was useful to answer questions in bulk.
5. Educators reported that given the capabilities above, they saved a lot of time that otherwise would have been spent dealing with class related communications and questions.
Disadvantages:
1. Users where skeptical in writing long essays.
2. Friction when used as a formal learning platform.
3. Private platforms have issues related to accessibilities and language. Communication was done in english even if that wasn't the case before;
3. Facebook doesn't support a wiki system.
4. There are no tools for group management.
5. There are no tools for sending bulk messages and group notifications.
6. No capabilities for deletion and archival of material.
7. No support for common multimedia (such as powerpoint slides or pdf).
8. Maximum characters limit for posts.
#### Behavior of the users
Advantages:
1. Users reached to older students and befriended them.
2. Users reported that they felt less pressure online.
3. Educators found that boldlier students asked more questions because of absense of face to face shyness.
4. Students help each other in answering questions
5. Six people from prior classes idependently requested to join the group

* The issue of privacy: forcing students to use a service that mines and sells their data is **unethical**.
* Identity pollution: the open web is based on the principle of pseudoanonimity, users should be capable of build a prism of different online identity for different communities and environments.

# The EduHack model
We need to develop a new LMS that is respectful of the Open Web standards without providing any friction to the users.
For this reasons, as part of the EduHack Project, we are developing the EduHack Knowledge Sharing Platform.
The EduHack Knowledge Sharing Platform was born around the assumption that many of the advantages in terms of user engagement and group dynamics
provided by OSNs could be replicated by adopting their widely known design patterns and mimicing closely the UX.
At the core of the platform there are the founding principles of the Open Web.
For this reason no data is collected of mined. Users are provided with an account that could be separated from their different online persona.
#### A platform for collaborative learning
The EduHack Knowledge Sharing Platform is divided into two parts.
The personal area is user centric and provides a window into the activities of the user in the form of multimedia blogposts.
The user can create and manage different roles for external editors to his private area. By default no other user is allowed to post a "story" in his personal area, but other users can be added as team members and can manage group works in different blogs.
Learners are expected to elaborate and remix what they learned (e.g. from online classes or MOOCs).
The public area is modelled after the UX of Reddit and it is divided into diffent sections (e.g.: mathematics, IT, discrete phisics, etc...), each providing a wiki.
Learners can subscribe to different sections or different users and be notified of new content or interactions.
Every user is allowed to post a link, an essay or any other widely adopted multimedia artifact to any section. Every user can positively vote and comment every post made. Comments can be positively voted as well.
Comments and content can be ordered by a custom algorithm (Wilson score interval) or chronologically.
Educators have a custom flair, can create new sections and moderate them. Moderation consists in changing links, removing posts or comments. Vote cannot be altered.
## Conclusions
The EduHack Knowledge Sharing Platform is an ongoing effort to evolve LMS and augment them with social features and modern group dynamics.
The UX is modeled after a widely used social network without sacrificing consolidated approaches from traditional LMS.
We want to provide with this model an ethically sound framework for user centric, knowledge-pull pedagogies.

Tempo fa rimasi colpito nel leggere questo [orientamento](https://www.courtlistener.com/opinion/110532/heffron-v-international-soc-for-krishna-consciousness-inc/) della corte degli Stati Uniti dal quale ho tratto la precedente citazione.
La libertà di espressione è un diritto molto potente che ha storicamente molteplici interpretazioni. Benchè ingenuamente potrebbe essere inteso come la possibilità di manifestare qualsiasi idea, ci sono delle situazioni in cui si deve intendere come il diritto di un individuo minoritario nel poter esprimersi liberamente e senza ritorsioni.
Con questa premessa posso inquadrare più facilmente il motivo per cui ritengo che il [ban del 2015](https://www.reddit.com/r/announcements/comments/39bpam/removing_harassing_subreddits/) da parte degli amministratori di Reddit nei confronti di /r/FatPeopleHate e altri subreddit di minor dimensioni non sia stata un'azione ipocrita rispetto agli ideali della piattaforma.

&lt;p&gt;Principalmente lo uso per scaricare tantissime registrazioni live di vari concerti registrati a mio avviso in maniera impeccabile.&lt;/p&gt;
&lt;p&gt;Nel sito si trova una guida per scaricare in bulk usando wget e gli strumenti del sito, ma risulta piuttosto prolissa e complicata se si vuole fare un download al volo.&lt;/p&gt;
&lt;p&gt;Questo e` lo script che uso, modificato da &lt;a href="https://github.com/ghalfacree/bash-scripts/blob/master/archivedownload.sh"&gt;questo&lt;/a&gt; script: e` scritto in bash e funziona su tutte le distribuzioni sulle quali e` installato wget, tail e sed.&lt;/p&gt;

&lt;p&gt;For 60$ I bought a cheap (but still good!) mechanical keyboard by Qisan, a clone of the Arduino Uno and a USB host shield.&lt;/p&gt;
&lt;p&gt;Given that is 3 years since I have been using a dvorak layout and it's a pain to change layout on every machine that you have to use.
You can imagine that given this three pieces of hardware together I put together an hardware key mapper for the keyboard.&lt;/p&gt;

&lt;h4&gt;Whose Security?&lt;/h4&gt;
&lt;p&gt;Let's define what security is. Security is the possibility to being set free from structural costraints, and as that we can distinguish various levels of security depending on who we are.&lt;/p&gt;

&lt;p&gt;Cosi` ha parlato il CEO di Nvidia Jensen Huang il 3 marzo scorso alla sua &lt;a href="http://www.gputechconf.com/"&gt;GTC 2015&lt;/a&gt;.&lt;br&gt;
L’attenzione di Huang si e` concentrata sul deep learning e come le deep neural networks negli ultimi anni abbiano compiuto progressi impressionanti tali da superare il cervello umano nei test di analisi immagine.&lt;/p&gt;
&lt;p&gt;Molta della ricerca negli ultimi anni, in particolare dal 2012 ad oggi, si sta concentrando sul programmare algoritmi tali da consentire alle intelligenze artificiali di processare dati in maniera gerarchica e organizzata tramite l’apprendimento progressivo dei livelli di rappresentazione.&lt;br&gt;

In quelle righe Gavin attribuisce l'identità di Satoshi Nakamoto, il padre dei Bitcoin, a Craig Wright, un imprenditore australiano.
Sono stato subito scosso dall'articolo, dove si spiega:&lt;/p&gt;

I want to explain briefly how you could check this claim.
The key in Wright's &lt;a href="http://www.drcraigwright.net/jean-paul-sartre-signing-significance/"&gt;post&lt;/a&gt; is this:&lt;/p&gt;

&lt;p&gt;Although I don't listen to a lot of electronic music, 2814 has been my go to music when I am programming and I go through a lot of James Ferraro's works during the day.&lt;/p&gt;
&lt;p&gt;What is the reason for my recent obsession on vaporwave culture?&lt;/p&gt;
&lt;h3&gt;A dream that disappeared&lt;/h3&gt;

&lt;p&gt;Ogni volta che un utente non loggato, o perfino senza account sul social network, visita una pagina che incorpora il bottone “like” o altri plugin sociali riceve un piccolo file di testo chiamato &lt;a href="https://www.facebook.com/help/cookies"&gt;cookie&lt;/a&gt; che incorpora una miriade di informazioni e la propria attivita` online in toto. Anche se si ha scelto per l’opt out un particolare cookie chiamato ‘&lt;a href="http://www.zdnet.com/article/facebook-tracking-cookie-returns-according-to-hacker/"&gt;datr&lt;/a&gt;‘ contenente un ID unico viene scaricato e mantenuto nella cache del browser identificando il computer dell’utente in maniera indistinguibile.&lt;br&gt;
Per quale motivo Facebook usa questo sistema di tracciamento?&lt;/p&gt;

&lt;p&gt;Principalmente lo uso per scaricare tantissime registrazioni live di vari concerti registrati a mio avviso in maniera impeccabile.&lt;/p&gt;
&lt;p&gt;Nel sito si trova una guida per scaricare in bulk usando wget e gli strumenti del sito, ma risulta piuttosto prolissa e complicata se si vuole fare un download al volo.&lt;/p&gt;
&lt;p&gt;Questo e` lo script che uso, modificato da &lt;a href="https://github.com/ghalfacree/bash-scripts/blob/master/archivedownload.sh"&gt;questo&lt;/a&gt; script: e` scritto in bash e funziona su tutte le distribuzioni sulle quali e` installato wget, tail e sed.&lt;/p&gt;

&lt;p&gt;La Rivoluzione Digitale ha toccato la societa` in tutti i suoi aspetti, e fra questi ha anche minato le fondamenta di un settore, quello dell’informazione, alle fondamenta della nostra societa`.&lt;/p&gt;
&lt;p&gt;La decentralizzazione delle fonti di informazione, che avviene attraverso i blog e le piattaforme online, la micro messaggistica istantanea e i tweet, i social media, ma piu` in generale tutti gli strumenti che Internet ci offre, hanno mutato radicalmente non solo il modo di fare giornalismo, ma il rapporto del cittadino digitale con l’informazione cartacea e digitale.&lt;/p&gt;
&lt;p&gt;Per questo abbiamo posto 12 domande a &lt;a href="https://twitter.com/cidigi"&gt;Carla De Girolamo&lt;/a&gt;, vicecaporedattore di &lt;a href="http://panorama.it/"&gt;Panorama&lt;/a&gt;, basandoci sulle parole di &lt;a href="http://blog.debiase.com/"&gt;Luca de Biase&lt;/a&gt;, il quale &lt;a href="https://www.youtube.com/watch?v=6al_1ELORXk"&gt;afferma&lt;/a&gt; che nel mondo dell’editoria la Rivoluzione Digitale e` stata una rivoluzione di tre nature: Francese, Copernica e Industriale.&lt;/p&gt;

&lt;p&gt;Per molti anni questi aerei avevano aiutato l’FBI con le operazioni di sorveglianza al suolo, ora invece sono stati equipaggiati con telecamere hi-tech e dispositivi in grado di tracciare migliaia di telefoni e risalire ai propri possessori anche se non si stanno effettuando chiamate, anche se a quanto detto dall’agenzia quest’ultima tecnologia è usata raramente.&lt;/p&gt;
&lt;p&gt;Charles Grasseley, presidente della commissione Giustizia del Senato, ha detto: “E’ importante che le forze dell’ordine abbiano gli strumenti essenziali per rintracciare e catturare i criminali, ma quando un’operazione monitora anche i cittadini americani che non sono sospettati, dobbiamo essere sicuri di salvaguardare la libertà degli americani innocenti”.&lt;/p&gt;

Un argomento sul quale si è discusso molto negli ultimi tempi è quello della crittografia dei dati, un ufficiale dell’FBI ha testimoniato che lo scopo delle forze dell’ordine è quello di collaborare con una società tecnologica per prevenire la crittografia. Anche se le compagnie non dovrebbero mettere l’accesso alla crittazione dei clienti prima di preoccupazioni per la sicurezza nazionale, perché la maggiore priorità del governo è quella di prevenire l’uso di tecnologie che proteggono ogni cosa che le persone fanno online. Il loro scopo non è quello di usare una “back door”, termine usato dagli esperti per descrivere punti di accesso integrati, ma quello di accedere ai contenuti dopo essere passati per un processo giudiziario.

&lt;p&gt;Negli ultimi anni abbiamo assistito all'ascesa di un gran numero di linguaggi di programmazione, in particolare &lt;a href="https://golang.rg"&gt;Go&lt;/a&gt; (2009), &lt;a href="https://www.rust-lang.org/en-US/"&gt;Rust&lt;/a&gt; (2010), &lt;a href="https://kotlinlang.org/"&gt;Kotlin&lt;/a&gt; (2011), &lt;a href="https://elixir-lang.org/"&gt;Elixir&lt;/a&gt; (2011), &lt;a href="https://crystal-lang.org/"&gt;Crystal&lt;/a&gt; (2014), &lt;a href="https://www.ponylang.or"&gt;Pony&lt;/a&gt; (2014).&lt;/p&gt;
&lt;p&gt;Questa esplosione di nuovi linguaggi è dovuta, fra le molte motivazioni, alla necessità di adottare paradigmi di programmazione non immediatamente recenti come cittadini di primo tipo.&lt;/p&gt;
&lt;p&gt;Rispetto ai più maturi C, C++ o Java, Python o Ruby questi linguaggi offrono "out of the box" supporto per:&lt;/p&gt;

Proviamo ora ad approfondire il concetto aggiungendo una proprietà fondamentale, la memoria.&lt;/p&gt;
&lt;h3&gt;Memoria e Stati&lt;/h3&gt;
&lt;p&gt;La rete neurale che abbiamo modellato non ha alcun tipo di memoria. con gli stessi dati di input, l'output è (quasi certamente) lo stesso.
Possiamo ampliare il nostro modello introducendo il concetto di &lt;em&gt;stato&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;Poniamo il problema della vendita delle auto in questo modo:
immaginiamo di avere un algoritmo di machine learning che valuti le auto e faccia delle offerte di vendita che conseguentemente vengono valutate da delle persone e accettate oppure rifiutate.
Ogni volta che una proposta viene accettata la teniamo in memoria e nell'aggiustare i pesi per la seguente offerta, teniamo in considerazione la validità dei pesi usati in precedenza.
In altre parloe, in ogni operazione di valutazione dell'auto salviamo lo stato dell'offerta precedente (rifiutata o accettata) e la consideriamo quando vogliamo proporre l'offerta successiva.
Abbiamo in questo modo una &lt;em&gt;recurrent neural network&lt;/em&gt; (RNN) dove ogni stato precedente viene utilizzato per modificare l'output dell'algoritmo.&lt;/p&gt;
&lt;h5&gt;Generazione di testo attraverso le RNN&lt;/h5&gt;
&lt;p&gt;Immaginiamo di voler creare un algoritmo che utilizzando una RNN possa generare del testo o prevedere quale sarà il prossimo carattere inserito (come nel caso del T9).&lt;/p&gt;
&lt;p&gt;Inizialmente dobbiamo permettere alla RNN di analizzare almeno qualche sample del nostro testo.
La RNN analizza carattere dopo carattere e costruisce un grande grafo dove collega ogni carattere al suo successivo.
Inizialmente l'output della nostra RNN non ha alcun valore:
in questo esempio, abbiamo l'output di una RNN allenata attraverso Guerra e Pace:&lt;/p&gt;
&lt;pre class="code literal-block"&gt;&lt;span&gt;&lt;/span&gt;tyntd-iafhatawiaoihrdemot lytdws e ,tfti, astai f ogoh eoase rrranbyne 'nhthnee e
plia tklrgd t o idoe ns,smtt h ne etie h,hregtrs nigtike,aoaenns lngty
&lt;/pre&gt;
&lt;p&gt;L'output prodotto dalla RNN, benchè non abbia nessun valore per un umano, viene analizzato dalla RNN per arricchire il grafo costituito inizialmente dai caratteri (e le loro relazioni) di Guerra e Pace.
Questo procedimento continua all'infinito.
Ogni volta che la RNN produce dell'output lo salva e lo riutilizza come input in maniera ricorsiva per generare nuovo output.&lt;/p&gt;
&lt;p&gt;Dopo 300 iterazioni abbiamo un output di questo tipo:&lt;/p&gt;
&lt;pre class="code literal-block"&gt;&lt;span&gt;&lt;/span&gt;"Tmont thithey" fomesscerliund

&lt;p&gt;Milan, December 2015, The Melvins were at the end of their most recent European tour when Jeff Pinkus drops the bass guitar, tunes the effects pedal and kicks the bass with his bare foot until the right repetition of sounds comes out of the speakers. Slowly, each one of the members leaves the stage, sounds are still coming from

&lt;p&gt;Nel mare di Internet assistiamo a due spiagge molto lontane che delimitano lo spazio della nostra attivita`: l’anonimato e l’identita` virtuale (che ci identifica nel mondo reale).&lt;/p&gt;
&lt;p&gt;E` un po` come misurare i due poli opposti, Facebook e Google Plus che richiedono il tuo nome vero e quindi ogni attivita` online e` un riflesso del proprio io reale, e 4chan, una delle poche risorse anonime nel Web che permette a ciascun utente di fare post anonimi e discutere quindi senza una forma di censura.&lt;/p&gt;

&lt;p&gt;Ogni volta che un utente non loggato, o perfino senza account sul social network, visita una pagina che incorpora il bottone “like” o altri plugin sociali riceve un piccolo file di testo chiamato &lt;a href="https://www.facebook.com/help/cookies"&gt;cookie&lt;/a&gt; che incorpora una miriade di informazioni e la propria attivita` online in toto. Anche se si ha scelto per l’opt out un particolare cookie chiamato ‘&lt;a href="http://www.zdnet.com/article/facebook-tracking-cookie-returns-according-to-hacker/"&gt;datr&lt;/a&gt;‘ contenente un ID unico viene scaricato e mantenuto nella cache del browser identificando il computer dell’utente in maniera indistinguibile.&lt;br&gt;
Per quale motivo Facebook usa questo sistema di tracciamento?&lt;/p&gt;

In quelle righe Gavin attribuisce l'identità di Satoshi Nakamoto, il padre dei Bitcoin, a Craig Wright, un imprenditore australiano.
Sono stato subito scosso dall'articolo, dove si spiega:&lt;/p&gt;

Un argomento sul quale si è discusso molto negli ultimi tempi è quello della crittografia dei dati, un ufficiale dell’FBI ha testimoniato che lo scopo delle forze dell’ordine è quello di collaborare con una società tecnologica per prevenire la crittografia. Anche se le compagnie non dovrebbero mettere l’accesso alla crittazione dei clienti prima di preoccupazioni per la sicurezza nazionale, perché la maggiore priorità del governo è quella di prevenire l’uso di tecnologie che proteggono ogni cosa che le persone fanno online. Il loro scopo non è quello di usare una “back door”, termine usato dagli esperti per descrivere punti di accesso integrati, ma quello di accedere ai contenuti dopo essere passati per un processo giudiziario.

&lt;p&gt;Although I don't listen to a lot of electronic music, 2814 has been my go to music when I am programming and I go through a lot of James Ferraro's works during the day.&lt;/p&gt;
