This is an experimental blogpost with the goal of improving myself on the design of system programs.
|
||
|
|
|
||
|
|
The following words are a flow that tries to recapture the process that I follow when I program.

# The problem
|
||
|
|
|
||
|
|
Yesterday I got an insider tip that probably http://isole.ecn.org/ might be taken down and I remembered that I had an old archive of the entire site.
|
||
|
|
Actually I am an amateur data hoarder so I keep archives/backups of pretty much everything I find amusing.
|
||
|
|
|
||
|
|
I wanted to update the archive so I used httrack.
|
||
|
|
I found the following problems:
|
||
|
|
|
||
|
|
1. too slow (doesn't even use 1/20 of my connection)
|
||
|
|
2. doesn't understand that if I want to mirror ecn.org I may want isole.ecn.org as well
|
||
|
|
3. if I configure httrack to archive everything basically I hit some external websites (like google.com) and it starts archiving that as well
|
||
|
|
4. I can't configure it to avoid any external link because I may need them
|
||
|
|
|
||
|
|
A perfect scraper for me would:
|
||
|
|
1. record a list of every external website it hit so that later I can archive them as well
|
||
|
|
2. allow me to scrape subdomains as well
|
||
|
|
3. configure a level of archiving for external websites
|
||
|
|
|
||
|
|
# The approach
|
||
|
|
|
||
|
|
Right now httrack does a perfect job of storing the webpages with a coherent folder layout and offline browsing capabilities.
|
||
|
|
Let's see how it does that.
|
||
|
|
|
||
|
|
On the original page I can found:
|
||
|
|
`<link rel='stylesheet' id='avia-google-webfont' href='//fonts.googleapis.com/css?family=Lato:300,400,700' type='text/css' media='all'/> `
|
||
|
|
|
||
|
|
When httrack saves it:
|
||
|
|
`<link rel='stylesheet' id='avia-google-webfont' href='../fonts.googleapis.com/css8f84.css?family=Lato:300,400,700' type='text/css' media='all'/> `
