WebRTC diagram of flow and their states: Overview of a peer connection lifetime (via: Alexandre Gouaillard on Google Groups)

Posted by jpluimers on 2014/03/07

From Alexandre GOUAILLARD:

I see a lot of questions on the mailing list, in my course, and during the meetups about the different states and flow of a peer connection. I thought I should share a slide that shows an overview of what you should expect, as it proved helpful for some as a reference.

Time for a new “-goto cleanup;+goto fail;” T-Shirt; The Story of the GnuTLS Bug (via: existential type crisis)

Posted by jpluimers on 2014/03/05

A new *n*x bug got discovered in TLS certificate handling that is similar to the recently discovered iOS and OS X “goto fail” security issue.

This time the fix is performing a few replacements linke this:

-goto cleanup;
+goto fail;

Plus one addition:

+fail: // ADDED
+ result = 0;

Applications depending on GnuTLS are affected (there are other libraries providing TLS like OpenSSL), which are many.

Two must-do things:

  • Closely watch the Linux, BDS, other *n*x and application security updates, as exploits will be available soon
  • Read via: existential type crisis : The Story of the GnuTLS Bug as it explains the bug, tracks down the cause, and talks about “lessons to learn”.

I’m with Jan Wildeboer here and updates should get in very soon: Read the rest of this entry »

Delphi “Variant Records”, a few notes

Posted by jpluimers on 2013/03/14

Variant Records are a feature that has been in the Pascal language since Standard Pascal.

A cool page for historic perspective is R3R: Pascal Features in Popular Compilers, hopefully someone will update it to more modern versions of the mentioned compilers.

There is not much official documentation on the Delphi side on this, so below some parts of a case I used for a project that started in 1997 and is still in use to day. Read the rest of this entry »
