121. Why Senior Engineers Let Bad Projects Fail
When I was a junior engineer, my manager would occasionally confide his frustrations to me in our weekly 1:1s. He would point out a project another team was working on and say, “I don’t believe that project will go anywhere, they’re solving the wrong problem.” I used to wonder, “But you are very senior, why don’t you just go and speak to them about your concerns?” It felt like a waste of his influence to not say anything. So it’s quite ironic that I found myself last week explaining to a mentee why I thought a sister team’s project would have to pivot because they’d made a poor early design choice. And he rightfully asked me the same question I had years ago: “why don’t you just tell them your opinion?” It’s been on my mind ever since because I realized I’d changed my stance on it a lot over the years.

135. Raspberry Pi's New AI Hat Adds 8GB of RAM for Local LLMs
Today Raspberry Pi launched their new $130 AI HAT+ 2 which includes a Hailo 10H and 8 GB of LPDDR4X RAM. With that, the Hailo 10H is capable of running LLMs entirely standalone, freeing the Pi's CPU and system RAM for other tasks. The chip runs at a maximum of 3W, with 40 TOPS of INT8 NPU inference performance in addition to the equivalent 26 TOPS INT4 machine vision performance on the earlier AI HAT with Hailo 8.

139. A letter to those who fired tech writers because of AI
Hey you, Yes, you, who are thinking about not hiring a technical writer this year or, worse, erased one or more technical writing positions last year because of AI. You, who are buying into the promise of docs entirely authored by LLMs without expert oversight or guidance. You, who unloaded the weight of docs on your devs’ shoulders, as if it was a trivial chore. You are making a big mistake. But you can still undo the damage.

149. Python: Tprof, a Targeting Profiler
Profilers measure the performance of a whole program to identify where most of the time is spent. But once you’ve found a target function, re-profiling the whole program to see if your changes helped can be slow and cumbersome. The profiler introduces overhead to execution and you have to pick out the stats for the one function you care about from the report. I have often gone through this loop while optimizing client or open source projects, such as when I optimized Django’s system checks framework (previous post).
150. I Hate GitHub Actions with Passion
I can’t overstate how much I hate GitHub Actions. I don’t even remember hating any other piece of technology I used. Sure, I still make fun of PHP that I remember from times of PHP41, but even then I didn’t hate it. Merely I found it subpar technology to other emerging at the time (like Ruby on Rails or Django). And yet I hate GitHub Actions. With Passion2. Road to Hell Day before writing these words I was implementing build.rs for my tmplr project. To save you a click - it is a file/project scaffold tool with human readable (and craftable) template files. I (personally) use it very often, given how easy it is to craft new templates, by hand or with aid of the tool, so check it out if you need a similar tool.
