Did someone publicly predict in the 80s or 90s that Welch would kill GE?

Suppose they’ve estimated the risk of failure (and killing the astronauts) as 10%. Then - returning Starliner empty is the correct decision - a successful return doesn’t indicate they were wrong about the risk - the experts will learn a lot

I don't get how that limits the packet size. If a sender's clock is 500 ppm faster than an intermediate node's, you need 500 ppm of slack. That could be short packets with a short gap, or large packets with a large gap. Ether

The treatment that makes people feel respected varies between cultures and genders, but the emotion is the same. In general, it's useful to disentangle your emotions from what you think is causing them. For example "I feel critici

The question is "Did you experience the following feelings during a lot of the day Yesterday? How about anger?" So it represents a pretty bad day. In my life, I think this would be true for less than 1% of days.

Inverters may be protected against changing settings, but if you can replace the firmware it can likely cause permanent hardware damage. Which the manufacturer, perhaps under pressure from its government, can do.

Travel speed matters too. At non-peak times, when queues are short, going 100 kph will give much shorter commute times than moving sidewalks (5 kph) or club cars (25 kph).

I'm not an expert here. But according to https://en.wikipedia.org/wiki/Diffraction-limited_system (see last paragraph of the intro) the diameter of a laser beam doesn't impose a diffraction limit on the optic

Why don't welding/cutting lasers add more divergence with built-in optics? Would it hurt performance? It seems like you could add 1 mrad and it would hardly make a difference at the usual working distance, but spread out to a mete

“Profit margin” doesn’t subtract the initial development costs, just current costs. So drug profit margins should be large to repay the billions previously spent in development.

Most Bakelite products were a molded combination of resin and sawdust. Though there were also pure resin products.

They could also just drop a device with a microphone in your bag and listen to both sides of every conversation. Involving bluetooth seems like an extra complication.

Is this known to work? I would have thought that running a whole tube at high temperature would cause the grid to emit thermal electrons, creating a current between grid and plate. Even though the grid doesn't have the low-work-functio

It would have to be able to fix your records in the IRS database, not just give you advice from the FAQ like most LLM support bots. Which could be awesome, but it'd have to be robust against prompt injection attacks and other bamboozle

If the error is the sum of many little errors, as it often is in mechanical assemblies, it's approximately normal due to the central limit theorem.

Many sanity checks are preserved with -O0, so they're still useful in debugging. And they serve as documentation of expected conditions. I often put in checks that I expect to be statically eliminated to remind myself what is supposed

Yes, in this case the title without the "how" is misleading, since it suggests they actually "handle" it and not just do whatever. So I think this title passes the howey test. Edited.

Clang has a mode (UBsan) that flags and optionally aborts if you execute UB. It runs several times slower because it has to check lots of things, but it might make sense for some programs.

I sleep in a light room wearing a mask. So my eyes are dark, but skin gets some light. My understanding is that melatonin is regulated by light through the eyes, so that should count as dark for circadian rhythm purposes. But I’d appreciate

Yes. The good news, if you're trying to develop tech to solve the housing cost problem, is that there are several labor-intensive processes that are easier to develop automation for than building the structure of the house. Like, a rob

The cost of the structure of a modern wood house is a tiny fraction of the overall cost. Most of the construction cost is in the wiring, plumbing, bathroom & kitchen fixtures, windows, flooring, etc. 3D printing doesn't help with a
