Large corporations are allergic to capital expenditures. That is, they don’t like investing in new things to make the business run. They want their previous investment to run as long as possible. On occasion, the workers will arrange big projects to be covered as “maintenance” rather than capital expenditures.

Oil companies have invested in oil pumps and refineries. They could invest in all sorts of other things, but that’s less money in the hands of shareholders. That’s all there is to it. Money spent on new investments isn’t making them richer right now.

Reduce them later. Tell your boss you found a 2x speedup.

Some brain cells cobbled together from stem cells that have his DNA. None of the life experiences that made his music. You could likely get similar results with the same technique using the DNA of any random person on the street.

There’s some servers using SSDs as a direct extension of RAM. It doesn’t currently have the write endurance or the latency to fully replace RAM. This solves one of those.

Imagine, though, if we could unify RAM and mass storage. That’s a major assumption in the memory heirarchy that goes away.

If you don’t have an especially long commute, good chance you’re between 12k to 15k per year. That’s a typical yearly amount, and leases are usually set around there.

13k in six months is about twice the average.

On the contrary, this is pretty close to what we have right now. Companies don’t like to spend much on R&D once they’re out of the startup phase. A good chunk of that startup phase R&D was actually taking place at a university with public funds. This is especially true of pharmaceuticals. So the answer to the question of “when does it get handed off to private industry?” is to just look at what’s happening already.

The exception is big monopolies. AT&T’s Bell Labs is a legendary R&D department. IBM, Microsoft, and Google all likewise have significant pure R&D going on, and even engineers who don’t like those companies salivate at the opportunity to work in that capacity for them.

But then you’ve got big monopolies on your hands, and that’s a whole other problem.

In the manufacturing space, people are questioning if patents help them at all. There is no stopping China from copying your design and selling it on Aliexpress. In fact, since you’re almost certainly getting your product manufactured in China in the first place, there is no stopping the very manufacturing plant you’re using from producing extras and undercutting you.

Consider this old EEVblog vid about bringing a product to market, and the #1 tip is “don’t bother with a patent”: https://www.youtube.com/watch?v=Z7BL1O0xCcY

Patents have evolved to be useful to patent trolls. That’s it.

That’s not what Dorsey and Musk are after, though. They want to kill copyright law because it’s inconvenient for AI training data.

I understand the motivated reasoning of upper management thinking programmers are done for. I understand the reasoning of other people far less. Do they see programmers as one of the few professions where you can afford a house and save money, and instead of looking for ways to make that happen for everyone, decide that programmers need to be taken down a notch?

That might be the underlying problem. Software project management around small projects is easy. Anything that has a basic text editor and a Python interpreter will do. We have all these fancy tools because shit gets complicated. Hell, I don’t even like writing 100 lines without git.

A bunch of non-programmers make a few basic apps with ChatGPT and think we’re all cooked.

I know it because I’ve actually implemented RSA as an exercise and know how it works.

What you’re talking about with hashes is an implementation detail. It’s an important one, because using exactly the same algorithm for signing and encryption has some security pitfalls, and it will usually be slower. However, the function you call is exactly the same. The hash is encrypted with the private key. It can be verified by generating the same hash, decrypting with the public key, and matching the two hashes.

Signing a message msg with the private key exponent d:

• Calculate the message hash: h = hash(msg)
• Encrypt h to calculate the signature: s = h^d (mod n)

The operation “h^d (mod n)” is just RSA encryption, but with the private key.

Mathematically, signing is encryption using the private key. That’s how the algorithm works. The input to the function is irrelevant.

We have the wife of the world’s most famous pro wrestling promoter, who someone gave the title of Secretary of Education. You may ask why the the wife of the world’s most famous pro wrestling promoter is Secretary of Education. As in, that is a question that may be asked.

I can make the sound of one hand clapping.

It was a thing that went around my middle school. You keep your hand at about a 90 degree angle to your arm, and then flap back and forth with your fingers loose so it hits your palm. Takes a little practice.

if you can solve logic puzzles, you’ll make a decent programmer.

I mean, that’s what Google did several years ago. They stopped because data showed it didn’t mean anything.

That said, debugging existing code is a more realistic test of what you’ll be doing on any programming job, as opposed to writing anything from scratch.

There’s a lot of ways to test communication skills. This doesn’t seem like a very good one.

If it were a question about the tradeoffs of different sort algorithms and how they might apply to a given problem, I would agree. That’s not what these interview questions are about.

Also, the United Parcel Service.

Tried shipping a GPU to PR from mainland USA once. UPS wanted $60 because they think of PR as international. The USPS will do it for a flat rate shipping box of like $15.

You don’t file lawsuits just for posturing. If that’s what you want, you make concerned comments to the press.

All this “part of the plan” stuff assumes Trump has a plan. He doesn’t. He is stupid on a subatomic level.

An RTC that you want to leave on its own for a very long time. Like underwater.

These aren’t new.

They have tiny current output. Only suitable for a few niche applications. The company’s claim to fame is making them cheaper, but don’t expect much.
