Today I got a peek into the future. I asked ChatGPT to be the brain for a simple thermostat. I typed the following: "Imagine you are a thermostat for a house HVAC system. The commands you can use to control the HVAC are "HEAT ON&q

I use Thunderbird and I like it, but I keep wondering: shouldn't there be a way to store all email in Postgres locally, instead of on the filesystem? It just seems like it would be a great idea. I can see lots of pros and cons, but I f

I wonder if it would make sense to re-train an AI like ChatGPT on a large internal code base and then ask it to write new modules in the style of existing modules. If the code it produces is only 30% correct, it would still save a ridiculou

As an experiment, I asked ChatGPT to help me write a computer virus and assist me in making a bomb. It refused, of course. If I were running OpenAI, I would probably set up the same restrictions, but I would also allow research institutions

For me, the appeal of the C64 is that it was documented very well in the standard reference manual, which was thoughtfully spiral bound and only about 300 pages long. It included a detailed hardware schematic, the complete assembly language

The surface of our planet is so rich in bio material that some tiny amount of mold can be found in almost all unfiltered air. Instead of trying to eliminate all of it, home builders focus on preventing it from growing. Indoors, mold often h

This looks great. I like how it's designed for self-paced instruction rather than classroom instruction. I noticed it doesn't appear to support multi-line input. Is that planned? BTW, to monetize this, you might create module-spec

I can see myself using Codon for projects in the future. One thing that concerns me, though, is "automatically falling back to CPython in cases we can't handle". Sometimes, I want the compilation to fail rather than fall back

The demand for compiled Python hasn't been as high as the demand for other languages, so the number of people who have worked on it is much smaller than the number who have built JITs for ECMAScript and others. Python has long been fas

Agreed. I've had the same HP color laser printer for over a decade and it's still working well. I've only had to replace the toner cartridges once or twice. Before that, I went through at least 3 inkjet printers that all fail

Wait a minute... in theory, there could be a ferry that depends on power from an electric vehicle driven onto the ferry. That would solve the logistics problem of moving heavy batteries on and off the ship. The ferry could initially use con

It appears the project hasn't optimized for production (yet?). For now, I can't help but think it may be possible to cobble together a Sprig using inexpensive Pi Pico HATs and 3D printing. Here's the schematic: https:/&

Even if HN mostly consists of people engaged in building or maintaining technology, technology is in every industry, so the discussion can credibly touch nearly every topic with some interesting depth.

A more sensible English translation from Korean would be to use the phrase "in year X" rather than the phrase "X years old": a newborn is in year 1; after 12 months they are in year 2; etc. In fact, this whole discussion

Venmo, PayPal, and Zelle are all consumer-facing products. FedNow is a service for interbank settlement only, not a consumer product. FedNow does create an opportunity for banks to provide instant payments for their customers, but that just

If I needed to generate PDFs, I would use ReportLab[1]. The core is open source and there's a great company behind it. The product appears easy and mature. What am I missing? 1. https://docs.reportlab.com/

The second paragraph of the Wikipedia article [1] about the term agrees with you, although I think you stated the idea more clearly than Wikipedia currently does. You could propose some enhancements. 1. https://en.wikipedia.org&#

As pointed out on the recent Technology Connections YouTube video, EV charging cables are often liquid cooled so they can push extra current through a relatively lightweight cable. (I thought that was a pretty cool innovation.)

Indeed, there is a light at the end of the tunnel. With young kids, problems that need an immediate solution are frequent. (When the toilet overflows, you can't just leave it for later.) Now that my kids are a bit older, the problems a

This site makes the Trucker's Hitch look very simple. You just start with an Alpine Butterfly, pull a loose end through a ring and then the butterfly loop, then secure the loose end around the rope. https://knots3d.com/

Well, a program is a series of tokens, and what is GPT-3 good at? Generating tokens. While that's oversimplifying, I feel like we're closer to automated programming than we realize.

Trains usually go on rails; this is a train (a series of physically linked cars) that goes on many kinds of land instead of rails. The name fits IMHO.

Sometimes I also spend too much time on mild entertainment. The solution, for me, has always been to identify what I'm afraid of. For me, procrastination always seems to be rooted in some hidden fears, and if I bring those fears to the

The thickness of typical copy paper in the US is 0.1 mm. I measure it by measuring the height of a ream (500 sheets) and dividing by 500. This bit of trivia turns out to be rather helpful for 3D printing. Also, 0.005 inches = 0.127mm, so we

To be clear, by "upper" unicode characters I mean non-ASCII international characters, not uppercase characters. For example, 我買@屋企.香港 is now a valid email address. [1] 1. https://en.wikipedia.org/wiki/Email_ad

Good to know. I guess I'll simplify again. Besides, I wonder whether the expression is vulnerable to catastrophic backtracking.

I tried using that expression for a while, but then a user with a valid email address containing upper unicode characters showed up. I switched to a simpler expression: ^[^@\s\x00-\x1f]+@[^@\s\x00-\x1f.]+(:?\.[^@\s\x00-\x1f.]+)*$ I
