A cert for .test.domain seems reasonable, for example, especially if the test infrastructure is dynamic, and you e.g. have CI/CD for a Cartesian product of: every branch * several test data sets * several feature flag / configu

It depends on the system design. If I have an organization like Google, with many employees, *.google.com would be a horrible cert. That's not every organization. I maintain many groups of /related/ servers (including dynamic

OP's political undertones aside, schools like Stanford and MIT fake a lot of data. I have zero ability to tell a school that some study they're relying on is faked if the author is at an elite school. This specific rot is in unive

No, but when Microsoft was founded, the pathway was open to Bill Gates since he went to a $$$$ elite private school which could afford a computer. That's right. One computer. Today, that path is open to everyone. The idea isn't th

He described specific functions which AI mostly took over. Those tended to focus on things like developing test cases, where before they had a test team. I didn't pick up that the people on that team were particularly impressive. I wou

It's not just the US anymore. A child in rural Jamaica can learn to program, if sufficiently motivated and ambitious. Arguendo, if the US has a gap there, that would only strengthen the macroeconomic trend I described. Why should I pay

About half of the best AI researchers I know are Chinese. I've visited universities there, and the quality of education is very high. There are a few barriers: 1) Language. Much of the stuff (including e.g. variable names and comments

I spoke to a CTO of a firm doing relatively cookie-cutter work (custom software for things like waste management). They were able to lay off a significant portion of their workforce due to AI. I think it's eating in more at the bottom-

It's strategic. China has amazing AI talent being developed. US is still generally a more desirable place to live. If that talent comes here, we'll maintain world leadership. If that talent stays in China, US competitiveness can c

Yes, it was a thing. And I feel like there are several headwinds: 1) Globalization. Many countries have better talent for lower-cost than the US now. Our school system sucks. This is not a bad thing, since it improves lives for hundreds of

I never said they didn't, and indeed, cited 100GB optical media. I said they made _limited_ progress. In 1982, a 20MB HDD was considered large, while a CD is 640MB. That's an almost insurmountable 20x advantage to optical. By the

No, it's not read-only. It's just that the writes are somewhat random, and in control of God and physics, rather than, of human design. (speaking as someone with a big pile of CD-Rs in the attic, most of which have some forms of c

Oft-missed pedagogical point for working with five-year-olds: Precision is important. You'll notice every comment I made was as simple as I can make it, but /technically correct/. I did not oversimplify to where I changed fac

Ergo, the TL;DR :) Even so, I oversimplified things a lot (a lot of the processes to leverage the silicon wafer, but some don't): https://en.wikipedia.org/wiki/Silicon_on_insulator One of the things to keep in min

The wafer is thick. Let's call it a mm thick (not quite, but close). Devices are tiny. The claim is 1.6nm, which isn't quite true, but let's pretend it is, since for the qualitative argument, it doesn't make a difference

My knowledge isn't current enough to offer more than speculation. However, something like an 80286 didn't even require a heatsink, while my 80486 had a dinky heat sink similar to what you might find on a modern motherboard chipset

This isn't quite right. Big wires (ideally entire planes) deliver power. Small wires deliver signal. Half and half isn't the right split, and you don't want to make power wires smaller. The very different requirements of the

ELI5: ICs are manufactured on silicon disks called wafers. Discs have two sides, and traditionally, everything was done on top. We can now do power on the bottom. This makes things go faster and use less power: * Power wires are big (and ca

Because it lost meaning somewhere between a micron and 100nm. From roughly the 1960s through the end of the 1990s, the number meant printed gate lengths or half-pitch (which were identical). At some point, companies started using "equi

Woah. That looks awesome. A red flag, relative to what I would do is: "Frequency to adapt the lights, in seconds." I would like to be able to make tight feedback loops, which means much less than seconds. I use HA + ESPHome as wel

The ESPHome project is unusually competent, user-centric, and almost uncanny in how well it works. I'll tell you what I want, though. I'm not sure this is in-scope for ESPHome, or how it's possible to even implement cleanly:

I agree about the harm that caused by that movement, but as much as Reagan was part of it, I have a hard time attributing the whole movement to him. FWIW, as much as a president has a soapbox to advocate from, budget and tax policy are set

That's actually what's surprised me. In my home, I found wifi to work better in all respects than ethernet. This is a relatively recent phenomenon. Ethernet has issues too, at times. I've certainly seen nominal 10Gbps network
