GNU: The GNU C Library, IRC Break, and GNUstep

  • Intel CET With Indirect Branch Tracking & Shadow Stack Land In Glibc
    Landing yesterday in Glibc for Intel's Control-flow Enforcement Technology (CET) were the instructions for Indirect Branch Tracking (IBT) and Shadow Stack (SHSTK). These Intel CET bits for the GNU C Library amount to a fair amount of code being added. The commit message explains some of the CET steps taken. The Control-flow Enforcement Technology behavior can be changed for SHSTK/IBT at run-time through the "GLIBC_TUNABLES" environment variable.
  • No Friday Free Software Directory IRC meetup on Friday July 20th
    No meeting will be taking place this week due to travel, but meetings will return to our regular schedule starting on Friday, July 27th.
  • Graphos GNUstep and Tablet interface
    I have acquired a Thinkpad X41 Tablet and worked quite a bit on it making it usable and then installing Linux and of course GNUstep on it. The original battery was dead and the compatible replacement I got is bigger, it works very well, but makes the device unbalanced. Anyway, my interest about it how usable GNUstep applications would be and especially Graphos, its (and my) drawing application. Using the interface in Tablet mode is different: the stylus is very precise and allows clicking by pointing the tip and a second button is also possible. However, contrary to the mouse use, the keyboard is folded so no keyboard modifiers are possible. Furthermore GNUstep has no on-screen keyboard so typing is not possible.

Security: Back Doors in Voting Machines, Two-Factor Authentication, Introduction to Cybersecurity, and Reproducible Builds

  • Top Voting Machine Vendor Admits It Installed Remote-Access Software on Systems Sold to States
    The nation's top voting machine maker has admitted in a letter to a federal lawmaker that the company installed remote-access software on election-management systems it sold over a period of six years, raising questions about the security of those systems and the integrity of elections that were conducted with them. In a letter sent to Sen. Ron Wyden (D-OR) in April and obtained recently by Motherboard, Election Systems and Software acknowledged that it had "provided pcAnywhere remote connection software … to a small number of customers between 2000 and 2006," which was installed on the election-management system ES&S sold them. The statement contradicts what the company told me and fact checkers for a story I wrote for the New York Times in February. At that time, a spokesperson said ES&S had never installed pcAnywhere on any election system it sold. "None of the employees, … including long-tenured employees, has any knowledge that our voting systems have ever been sold with remote-access software," the spokesperson said.

  • An Introduction to Cybersecurity: The First Five Steps
    You read all these headlines about the latest data breaches, and you worry your organization could be next. After all, if TalkTalk, Target, and Equifax can’t keep their data safe, what chance do you have? Well, thankfully, most organizations aren’t quite as high profile as those household names, and probably don’t receive quite so much attention from cybercriminals. At the same time, though, no organization is so small or insignificant that it can afford to neglect to take sensible security measures. If you’re just starting to take cybersecurity seriously, here are five steps you can take to secure your organization more effectively than 99 percent of your competitors.
