Has anyone here done cool stuff with home assistant? Looking for some creative ideas! Mqtt and Zigbee are available, as is the rest of the standard stuff.

Many firms invested heavily in AI, afraid they’d miss the bus. Turns out, bus was going in wrong direction. They would’ve been better off not investing in #AI w/o first knowing costs, use cases, or even what AI was supposed to do for them in first place. https://t.co/uJemOarUht

@alexstamos I could see a scenario where each team gets one or two appeals per game, but that’s it. Not this constant second guessing of decisions. And a check needs to be time bound.

I'm trying to upload a file (about 800MB) into a locally running DeepSeek model (ollama and open-webui), but the ui times out before it finishes processing. Any suggestions on how to fix that? I guess I could split it up in multiple smaller files, that seems like effort ;)

The alure of listening to shortwave radio transmissions directly from antenna to transceiver and without any network or computer attached remains strong. Too bad most of the utility signals are digital and (presumably) well-encrypted.

Still-- there are some things that sound like human voices (numbers stations, hfgcs, atc, amateur, etc.)

I have been away from Twitter for a while. While trying to catch up on what happened during my absence, lots of AI and ML tweets dominate my timeline. That was fully expected.

But more surprising: I keep seeing tons of posts that imply that the only way to be secure is by stacking a ton of technologies on top of the stuff that you’re supposed to be defending.

Solving crap with more crap seems to be a fundamentally flawed approach. Are we sliding back to the mentality of the early 2000s but just with fancier toys?

Essential Computer Science Lore

Watching a class of undergrad CS students work on a midterm exam for a C programming course was a good motivator to start putting together this list of “Essential CS Lore”.

@mattjay Any day and every day :-) We should touch base some day soon. Lots of good things happening here!

[Kees Leune W2CJL @leune]

@mattjay Thank you, on their behalf!

[Kees Leune W2CJL @leune]

Willing to give @[email protected] on Mastodon a shot. Hoping for a much better signal-to-noise ratio over there

[Kees Leune W2CJL @leune]

So. In line with continuous contingency planning. What will the infosec to the Twitterverse be?

Not bad. 50W on 17m

A solar flare index of 252 is probably one of the higher ones I have seen in a long time. Let's see what this does to propagation conditions!

[Kees Leune W2CJL @leune]

@mattjay School year just started. I'm there 5 days a week! Let me know when, and I'll try to arrange it!
