We stopped roadmap work for a week and fixed bugs

We stopped roadmap work for a week and fixed 189 bugs

It’s Friday at 4pm. I’ve just closed my 12th bug of the week. My brain is completely fried. And I’m staring at the bug leaderboard, genuinely sad that Monday means going back to regular work. Which is weird because I love regular work. But fixit weeks have a special place in my heart. What’s a fixit, you ask? Once a quarter, my org with ~45 software engineers stops all regular work for a week. That means no roadmap work, no design work, no meetings or standups. Instead, we fix the small things that have been annoying us and our users: an error message that’s been unclear for two years a weird glitch when the user scrolls and zooms at the same time a test which runs slower than it should, slowing down CI for everyone The rules are simple: 1) no bug should take over 2 days and 2) all work should focus on either small end-user bugs/features or developer productivity.

I've been wanting to start a blog for a while, and finally decided to bite the bullet.

The first article of hopefully many more to come is about, you guessed it, profiling & optimization.

Boosts appreciated!

Optimizing libdwarf .eh_frame enumeration | Ritesh Oedayrajsingh Varma

For the Linux version of Superluminal we rely on unwind information stored in the .eh_frame section in a binary to perform stack unwinding. We’ll go over optimizations we made to libdwarf that greatly improve the performance of retrieving this information.

Why I (still) love Linux

I usually publish articles about how much I love the BSDs or illumos distributions, but today I want to talk about Linux (or, better, GNU/Linux) and why, despite everything, it still holds a place in my heart.

This is a beautiful machine. A bartop arcade cabinet with a wood look running Linux Mint.

Looks like it was built in the 70's or 80's.

hackaday.io/project/202861-bar

Bartop Arcade Cabinet From Scrap and E-Waste

This is my bartop MAME cabinet, scratch-built from common materials at very low cost. It's powered by an old Dell Inspiron all-in-one PC running Pegasus Frontend via Linux Mint. Controls are interfaced by an Xbox360 gamepad hack, and audio is handled by Logitech amplified desktop speakers. Joystick and buttons are IL-knockoffs originally sourced from Microcenter. Cabinet system devices are controlled by relay to respect the power state of the PC. The cabinet was designed to be as compact and portable as possible within the size constraints posed by the hardware and monitor. It is constructed of scrap plywood and finished with vinyl laminate, pvc edge trim, and masked/painted acrylic sheet overlays. The control panel is built to allow for easy panel swaps for different control options. This was a really fun project to put together and complete, offering lots of fun little engineering challenges. It's proven to be popular at parties and a lot of fun to play.

NEW: U.S. banking giants and mortgage lenders are scrambling to figure out how much of their customers' non-public banking data was stolen during a cyberattack on a financial tech firm earlier this month.

Customers of at least JPMorgan Chase, Citigroup, and Morgan Stanley are said to be affected.

Using over (DNS over TLS) as a local DNS resolver.

Example setup on - of course not limited to - any distro or will do! 😎

Using Unbound

We all know that DNS is the lifeblood of the modern Internet. But, we also all know that resolving DNS queries can take some time and by default queries are sent unencrypted to a outside DNS server - if one does not selfhost DNS of course. In this little post I set up Unbound with DoT. Also, Unbound will cache results which makes queries faster in the future (Since these don’t need to be resolved again)

今天港府公佈投入宣傳立法會選舉的開支是1.77億港幣，比上屆多77%

2019年區議會是最後一届相對民主的投票，投票率71%
2021年「完善選舉」後，立法會地區投票率30.2%，是自1991年有選舉以來最低；
2023年區議會選舉投票率則是近28%

今年任何超過30%的數字都會被視為成功吧
