@mos_8502 I started programming seriously in editors like this, so many feelings. There's also "joe", which I used for kernel programming for a couple of decades.

This is the Xgecu T48 universal programmer, arrived with a Lunar New Year gift. The T48 supports over 32000 chips, including a bunch that of older MCUs such as the PIC16C*

@mekkaokereke I'm really enjoying the lack of "hot takes" and dunks. here. When I look back at Twitter, it's people sweating out one-liners.

Can we embed videos here? Here's some nice #winlink activity, getting 3230 bps on 30m, over a distance of 400km. The 2750 Hz bandwidth is nice if your rig supports it!

Are you someone who has a simple fix for something in the Linux kernel, but haven't bothered submitting a patch because you find the email workflow daunting? Can be a bugfix, spelling correction, anything at all.

If so, I want to talk to you! I have tools that simplify this process quite a bit, but I need more feedback from people who aren't long-term Linux maintainers.

Please reach out, either via here or by emailing mricon@kernel.org.

A couple of pages from Alan Turing’s 1940 treatise on the Enigma machine. Is there a important piece of reverse engineering?
