Saw a lot of Aurora flying over Greenland on the way to Linux Security Summit EU. This is the best I could do with an older iPhone #linux #linuxsecuritysummit #space #spaceweather #hamradio #amateurradio

We quietly released the code a little while ago but this is the official announcement of Capslock, our contribution to the supply-chain security conversation.

https://security.googleblog.com/2023/09/capslock-what-is-your-code-really.html

Capslock is a tool for understanding at high level what a given piece of (Golang) code is capable of and for detecting when an update to a library changes this capability set, to give users a chance to catch supply-chain attacks in progress.

After many hours, including re-capping the power supply (no dice, but worthwhile in any case), and tracing through most of the upper section, I finally found the issue with this Tektronix spectrum analyzer. A tantalum cap on the horizontal storage board failed and shorted the +15v bus. Replaced it and the SA seems to be working ok so far. #hamradio #amateurradio #electronics

@mcdanlj I'd read that spiral flute taps are weaker and more likely to break for small taps, so I haven't tried them yet. Thanks for the pointers!

Metalwork for the linear amp is going GREAT. First I drilled the wrong hole sizes for the heat sink, then broke two 4-40 taps. Will figure out how to extract these then try a thread forming tap instead of a cutting tap.

Anyway, something good -- found a building full of electronics stores in Singapore a couple of weeks ago. So much stuff you don't see on shelves in the US or Australia now, all kinds of niches.

Location is Sim Lim Tower.

You realize that the Fediverse or Threads or bsky could be the new Twitter by next week, right? If a moderate handful of major celebrities and their sponsors got together and jumped to one of these, it would start an avalanche.
