Yes, the entire field of software engineering ran aground on not being able to test how well people can write software. But I'm more optimistic about testing programming models. You can run repeated tests, and compare median performanc

Field termination is necessary when the connectors are too large to pull through a conduit. But if they were USB-C sized, you could just pull fully assembled cables.

You can rotate your voice with substantial effort. Just speak differently: higher or lower pitch, a different accent. Your friends may look at you funny for the first few years.

If you have something interesting you made yourself, and not some vibe-coded AI slop project, email the mods at hn@ycombinator.com and they can enable your account.

Of course, when everyone sets min-release-age=7, supply chain attacks won't get noticed until 7 days later. So you should set min-release-age=14 and be safe forever.

I understand the appeal from AWS's perspective. Customer A pays for a 32 vCPU VM, which they run on 32-core hardware. Then they can also squeeze in customer B's 1 vCPU instance running a blog, and no one notices. Free money! But I

I think clouds pay a huge abstraction penalty to allow tiny VMs. I guess it helps with onboarding and $10 personal VPNs. But I have never needed a fraction of a computer. I want to rent some number of full computers of various sizes, consis

Cool, but why is the most rounded-off part in the center? My wrists cover the edge at 5-25% and 75-95% when typing. When mousing, my right hand fleshy pad covers the edge at 65-80%.

You’re free to invest that way if you want. You might one day wake up and wonder why your Blockbuster Video shares did so badly. But Netflix seemed way overpriced. Investing in future prospects encourages companies to plan for the future, r

Yes, and indeed more startups are addressing more markets every year. The total number of attempts and successes are both up, keeping the success rate fairly constant.

The fact that the survival rate of startups hasn't improved doesn't show that our knowledge hasn't improved. Startups are competitive, with only 1 or 2 VC-scale winners per market. So, the claim is like "race car technol

I think the total light output of each bulb in the pair is the same at all points in time, but the orange-blue gradient is reversed. So when one is orange at one end, the bulb beside it is blue at that end. IIRC, the end that's negativ

You and I look with dismay at the high prices, but remember that a million hospital administrators are high-fiving themselves. So ideas like "just cut waste" are opposed by a large group with a lot more skin in the game.

Heat goes up with the square of current, so putting 10x the current to get 10x the force means 100x the heat. Still, I think this idea is under-explored. There are probably applications for robots that move really fast, but only for a secon

One scenario: there's a short circuit somewhere, say rats chewing through insulation. This can cause a very high current through the short. A non-inverter 4500 watt 120 volt generator might have 0.2 ohms coil resistance, so the short c

I'm interested in this, but only passingly familiar with it from several years ago. Can you link to what you believe the current state of the art is?

Isn't that essentially what happened? In the 1930s, the channels were allocated at 6 MHz spacing, but only needed about 3 MHz of bandwidth for the luma channel. There might have been some foresight involved, but the gaps between channe

Oil prices are affected by many other things too. It's valuable to isolate individual factors.

It's easier to ban things before they become entrenched than after. Banning stock trading is hard today because most senators have been doing it for years before getting elected. I'd be in favor of senators doing prediction market

Great images, OK writeup. There are some bits of bullshit, like "The proximity of microphones to processing hardware minimizes latency". No, the speed of electrical signal propagation (around 2/3 the speed of light) is not si

Many of the great hacks have involved breaking through 2 layers of supposed security. You break into the 3D printer, which lets you send packets on the local network. Then you use that to break into the exercise bike, which has a camera bec

The rate at which molecules of plastic sublimate off the surface of the enclosure is probably a much larger amount of mass. The rate increases with e^kT, where k is such that it doubles about every 10 degrees C. So if you get a drive and fi

International orgs usually need a company incorporated in every country they're working in. You need it to pay employees, for instance.

Compilers only do one file at a time, but an LSP needs to parse all the files. Also, an LSP needs to update incrementally when you edit the file, not just when you compile.
