vscode freezes or crashes when opening a large folder by Ciro Santilli 37 Updated +Created
The issue appears to be that the file watcher goes out of control.
The reproduction is very simple:
mkdir mytest
cd mytest
seq 1000000 | xargs touch
code --disable-extensions .
and now the editor GUI hangs and Ubuntu shows a popup:
The window is not responding
htop reveals a bunch of processes or threads of type:

CIA 2010 covert communication websites / Split header images by Ciro Santilli 37 Updated +Created
Many of the website banners are composed of several images cut up.
Often stock images were first assembled into the banner, and then the resulting image was cut.
Possibly this was done to make reverse image search to their stock image provider harder.
But it somewhat backfired and serves as a good marker that confirms authorship.
Maybe it is some kind of outdated web design thing, which they took much further in time than the average website, like the JAR.
Their websites do appear to follow common style guidelines form earlier eras, around the early 2000s notably, some legit sites that look a lot like hits:
Looking at the source code of: web.archive.org/web/20130828122833/http://euronewsonline.net/euro_bus.php we noticed an interesting comment:
<!-- ImageReady Slices (enewsweather.psd) -->
which presumably refers to Adobe ImageReady:
Adobe ImageReady was a bitmap graphics editor that was shipped with Adobe Photoshop for six years. It was available for Windows, Classic Mac OS and Mac OS X from 1998 to 2007. ImageReady was designed for web development and closely interacted with Photoshop
A sample tutorial: people.goshen.edu/~paulmr/physix/326/imageready/slicendice.php
Some of the websites use CSS background images to populate the images, e.g. ingenuitytrendz.com has HTML:
ingenuitytrendz.com/20110201170354/index.html:                  <li><a id="banner1">&nbsp;</a></li>
ingenuitytrendz.com/20110201170354/index.html:                  <li><a id="banner2">&nbsp;</a></li>
ingenuitytrendz.com/20110201170354/index.html:                  <li><a id="banner3">&nbsp;</a></li>
and then the CSS engineering.css does:
#banner1 { background: url(/web/20110201170405im_/http://ingenuitytrendz.com/images/banner_01.jpg) no-repeat center; }
#banner2 { background: url(/web/20110201170405im_/http://ingenuitytrendz.com/images/banner_02.jpg) no-repeat center; }
#banner3 { background: url(/web/20110201170405im_/http://ingenuitytrendz.com/images/banner_03.jpg) no-repeat center; }
Updates / Backing up CIA website archives for research and posterity by Ciro Santilli 37 Updated +Created
I've downloaded and uploaded copies of the archives of the CIA websites as follows:
The cqcounter screenshots don't offer too much information, but having the wayback machine ones could actually reveal new fingerprints and other website information leaks.
We've had a very quick look, and while there was nothing mind blowing, there were some small finds.
mynepalnews.com actually has several archives for a /stats path which contains HTML reports generated by Webalizer, an analytic tracker that tracks the source of incoming traffic!!! It is hard to believe that the CIA would have left that there. Particularly ridiculous is the presence of inurl:cgi server_software at web.archive.org/web/20110204095809/http://mynepalnews.com:80/stats/usage_200805.html which is almost certainly a Google dork search, which we know is something that the Iranians used to find the websites. That search hits under /cgi-bin/check.cgi. That page is itself os some interest containing SERVER_ADMIN = mmadev@mmadev.com. web.archive.org/web/20110204095815/http://mynepalnews.com:80/stats/usage_200806.html also reveals several request IPs. Even if this is not a CIA website, there's a chance we could find the IP of the Iranian counter-intelligence in these IP list, it's mind blowing. There's lots of referrer spam too as well. Further HTML inspection however seems to show close relationship to that HTML and other confirmed hits.
globaltourist.net, if is actually a hit, likely has a a 2003 archive, which would be our earliest hit archive so far.
A fun fact is that looking at the source code of: web.archive.org/web/20130828122833/http://euronewsonline.net/euro_bus.php we noticed an interesting comment:
<!-- ImageReady Slices (enewsweather.psd) -->
which clarifies that the CIA likely used Adobe ImageReady to cut up the images for Split header images:
Adobe ImageReady was a bitmap graphics editor that was shipped with Adobe Photoshop for six years. It was available for Windows, Classic Mac OS and Mac OS X from 1998 to 2007. ImageReady was designed for web development and closely interacted with Photoshop
We also understand that the tool likely outputs the layout to HTML directly, and leaks the adobe projects filenames (.pds files) in the process.

Pinned article: ourbigbook/introduction-to-the-ourbigbook-project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.
    Figure 1.
    Screenshot of the "Derivative" topic page
    . View it live at: ourbigbook.com/go/topic/derivative
  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
    Figure 5. . You can also edit articles on the Web editor without installing anything locally.
