• BSidesSF CTF 2018: Coder Series (Author's PoV)

  As the author of the “coder” series of challenges (Intel Coder, ARM Coder, Poly Coder, and OCD Coder) in the recent BSidesSF CTF, I wanted to share my perspective on the challenges. I can’t tell if the challenges were uninteresting, too hard, or both, but they were solved by far fewer teams than I had expected. (And than we had rated the challenges for when scoring them.) The entire series of challenges were based on the premise “give me your shellcode and I’ll run it”, but with some limitations. Rather than forcing players to find and exploit a vulnerability, we wanted to teach players about dealing with restricted environments like sandboxes, unusual architectures, and situations where your shellcode might be manipulated by the process before it runs.

10 Great Linux GTK Themes For 2018

Customization is a big part of the Linux experience, and your desktop theme is no exception. The world of Linux desktop themes is an ever-evolving one, with new ones replacing old favorites all the time. Of course, the desktop environments and GTK itself are always changing, so that adds another dynamic element to consider. That said, some of the best desktop customization happens on the simplest desktop environments, like XFCE. As of now, in early 2018, there are some really excellent GTK themes available. These themes aren’t ranked in any particular order. That comes down to a matter or preference. Any one of them can add a whole new look to your GTK-based desktop.

Ubuntu “Testing Weeks”

• Ubuntu To Discontinue Opt-In Development Milestones In Favor Of Test Weeks

  The proposal for replacing early Ubuntu derivatives' early alpha/beta releases with "testing weeks" in its place is moving forward with no objections having been raised but flavors like Kubuntu and Xubuntu being in favor of the change.

• Ubuntu Linux Replaces Alpha/Beta Release Model With “Testing Weeks”

• Re-evaluating Ubuntu's Milestones

  Happy Release Week! I do not believe there have been any -1s to this proposal from any flavor, nor from the Release Team, so I think it's time to move forward with it. In summary, what will now happen from here on out is that opt-in milestones will be discontinued in favor of testing "weeks" (Tuesday through Thursday). I can organize the testing weeks for the 18.10 cycle (so we can get a process going), but from the 19.04 cycle and on, representatives (probably Release Managers) from any active flavor can (and should!) organize these testing weeks. Additionally, I will look into the automated testing Steve brought up shortly after the 18.04 release, with the goal being to adopt that sooner rather than later. I'll write a follow-up email to ubuntu-release once I have something to show for that. Thanks everyone!
