HalfCrimp··on Show HN: I replaced a $120k bowling center system with $1,600 in ESP32s
> On a topic not exactly related to the implementation of the ESP32 and hardware, what other R&R activities can one add to a bowling alley to make such a facility more popular and attractive for the locals?

Pinball seems to be having a bit of a renaissance in some areas

HalfCrimp··on Bonsai 27B: A 27B-Class model that runs on a phone
Running an llm on a PC running a desktop environment really isn't that bad. You lose a bit of ram & vram but that only matters if you _reaaaally_ want to push to the max model size your hardware can handle.

The biggest issue I've found is absent mindedly opening YouTube or the like that spike ram requirements and freezing the system up. But that's a me problem

HalfCrimp··on I baked a pie every day for a year
I suspect they mean "days that I deal off" rather than "every day". Even elite climbers struggle with ligament issues climbing every single day
HalfCrimp··on Claude Sonnet 4.6
A reference to one of the hall of fame Robber Barons does seem pretty apt right now..
HalfCrimp··on The serotonin theory of depression: a systematic review of the evidence (2022)
I had similar insomnia issues with bupropion (which was otherwise greatly superior to SSRIs for me) until I started taking it immediately before going to sleep. I slept slightly shorter than usual, but woke up feeling great and had no issues getting to sleep.
HalfCrimp··on Keras 3.0
I'm a bit of a novice in the space, if keras isn't for inference, what's the intended workflow?

Train with keras and then?

HalfCrimp··on Iceland declares state of emergency, braces for volcanic eruption [28 min ago]
Iceland uses patronymic naming [1] so you get a lot of this sort of thing. A child's surname will be their father's name plus a suffix depending on the child's sex. So the son and daughter of Thor will have surnames like Thorson and Thorsdottir, literally "Thor's son" and "Thor's daughter"

HalfCrimp··on What every developer should know about GPU computing
If you are comfortable with C++ already then look at Thrust. It's nvidia's analogue to the standard library arrived at GPU computing.

Writing and launching raw cuda kernels is too low level for me, but writing with Thrust makes it feel pretty similar to writing regular C++ code. You still need to deal with moving data from host to device and back, but that's as simple as assigning a `thrust::device_vector` to a `thrust::host_vector`

HalfCrimp··on Improving sleep
It certainly did for me.

I was a regular espresso drinker, one in the morning with my wife before work and giving it up has made a world of difference. Even a coffee at 7am was impacting my sleep, I suspect I just metabolise caffeine slowly.

I can still have a tea in the morning to replace the ritual, and chocolate doesn't cause me any issues (in moderation) so I'm not 100% caffeine free, but it's made a huge difference to my sleep quality and overall mood. The first week or so felt very sluggish, but one I was sleeping properly I now feel more alert and productive without coffee than I ever did with it.

I still have one occasionally (~2 a month I guess) because I enjoy it, but I definitely notice the sleep impact that night and feel crap the next day.
