which city is that? I want to move there with my children.

If you desperately want mediocre chromebook instruction for your children; where your classmates turn in ChatGPT essays as original work, feel free to move to Virginia.

Lots of sensors these days will give you 10 or 12 bits of data per color channel. You may want ordered dithering when previewing on an 8 bit display.

Is the code actually good though? Not seeing any benchmarks vs numexpr, numba, or Jax

Sublime Text? Sure, doesn't have the long tail of extensions, but surely most people don't need those. The biggest issue with ST being the fact that it costs money...

Even if you don't like the current administration, the rank and file are still out there doing valuable work. The government is more than ICE; it also administers welfare, funds research, collects taxes, and distributes social security payments to the old and infirm.

So? If the goal was to attract corporations you'd release under a BSD license.

New comment by krapht in "Ask HN: Chromebook leads for K-8 school in need?"

krapht — Mon, 23 Feb 2026 01:07:35 +0000

This post makes me sad for two reasons:

1) kids k-5 are using laptops 2) websites are so bloated today that browsing on a Chromebook is causing agitation

Otherwise I don't have anything topical for this post, but good luck OP

Yes, but is this a problem? Haven't most betting markets turned out to offer accurate predictions?

The human is responsible. How is this a question? You are responsible for any machines or animals that work on your behalf, since they themselves can't be legally culpable.

No, an oversized markov chain is not in any way a human being.

Why not have a megatopic for things that don't need their own topic?

Topics are necessary when you start having a huge Zulip server, 100+ people. There's so much noise --- dividing things by channel is too coarse.

I participate in several open source Zulip servers and it reminds me of a better IRC. It's a lot more ergonomic that Gitter or Discord.

I've seen some small firms crash and burn too, though. The problem is small firms are easy-come, easy-go; they don't have enough reputation at stake. Not sure what a good solution is.

Yeah, I know three - one transitioned to teaching, another to being a paramedic, and the last to social work.

On the other side I also know a teacher who switched to cyber security for the money after he started a family.

You have to know yourself and what motivates you to know if you'll find things more meaningful elsewhere.

What you suggested has been done before - you might find a review of the literature fun if this sort of thing interests you, even if academic papers are pretty dry reading normally.

It wasn't labor costs that made the Roomba twice a Roborock, but manufacturing costs. Roomba teardowns basically show that iRobot was just really bad at cost-optimizing their vacuums for mass production.

There's no way to get through the harder courses in the program on 1 hour a day. And you're not getting value from the degree if you aren't pushing yourself to take those hard courses, unless you just need the diploma.

This is a standard which few kernels will ever meet. I'd say requiring a numerical proof is the same as requiring no proof at all - because it won't ever happen unless you're validating silicon or something equally expensive.

Why can't delayed spending be categorized as a claim to future goods (savings)?

C++: "look at what others must do to mimic a fraction of my power"

This is cute, but also I'm baffled as to why you would want to use macros to emulate c++. Nothing is stopping you from writing c-like c++ if that's what you like style wise.
