If you think this is bad, it's going to get 1000x worse with WASM. A lot more rope there. You will see the Linux kernel being pulled in because someone used system threads.

It's literally built in to most databases. If that's rolling my own, I also roll my own for loops.

He's not wrong. ext4 is actually maintained. This matters. ZFS hasn't kept up with SSDs. ZFS partitions are also almost impossible to resize, which is a huge deal in today's world of virtualized hardware. Honestly Linus'

Ruby blocks are another example of something that looks like a functional programming feature but is actually not. As in Java 8 and C++11, which also added lambdas, it doesn't have much in common with FP lambdas. These are essentially

Why can't pattern matching fit in OOP? It's not really functional, despite being in most functional languages. It's just sugar for more lengthy imperative conditionals and unpacking.

What is your opinion on Blow's Jai programming language?

I guess it's the recitation and active recall that helps--not necessarily the writing/typing stuff down on paper itself. I suppose it's also possible to do this by drawing on a whiteboard or...eek...preparing and drilling fla

I think it's really useless to take notes on what is already written in 1000 other places with much more legibility and coherency. Sometimes I see people with tomes of notes that is basically a duplicate of the textbook, and I can&#x27

Idk, $120k is still a lot. You are still begging the question that money even matters. There's an elephant in the room: Basically men have vastly overestimated the importance of wealth. A chart of the importance of wealth would drop of

Not that I disagree (what you said is almost certainly true) but it's funny how both sides can unite on this Randian take. Horseshoe theory.

You are more likely to lose your data while the computer is on and drives decrypted than when it is off. The threat model for FDE is thieves or government physically stealing your drive. Much more people get pwned in software than physicall

Firefox's killer feature was generating sync keys locally and letting you self-host a compatible sync host. Chrome generates the sync keys on server and has proprietary sync software. That's it. That's all it took for me to s

Nah there isn't, I looked. There's Scala, but I don't have 5 years lying around to get up to speed on it.

I'd try F# if it were hosted on JVM or better yet LLVM. Unfortunately .NET is borderline nightmare inducing so I wouldn't want to spend my free time using it. And it doesn't seem to have any better adoption than OCaml which i

It's most useful in design. Honestly it's not that useful otherwise and just kills attention span in my experience. Basically we went from doing design WYSIWYG-style to completely in markup languages and CSS. So hot reload bridges

Arguably Skaffold and other container tools are approaching Webpack in its nonstop build-edit-rebuild workflow. But it's still not part of the code's build process. I'd like to see something like Webpack for native code. The

You act like the fashion is not tech. Their stuff looks good because of engineering all the way down. Looking good is a feature. I disagree with the idea that it's marketing. Apple does very little marketing these days. Apple products

To be fair trading is a zero-sum game with extreme information asymmetry between players. Business/investment is mostly positive-sum. I don't think we can extrapolate lessons from trading to the real world except the lizard-brain

What you call sunk cost I call "equity"--whether that be tangible capital or human capital. If you never believed in it, then you should drop it by all means. But if you take the sunk cost fallacy to heart, you will give up whenev

The problem with SSNs is how short they are. 9 digits. Even if you hash them, it's not that hard to make a 10^10 - 1 rainbow table. It's the same problem with IPs (v4). You simply cannot store them at all if you care about your cu

Most documentation is so bad and so often out-of-date that I can answer my question faster by reading the source (or tests). Everything is so extremely verbose. I don't want to read a 7 paragraph essay about how this or that feature wa

They are trying to convince people to use C++ instead of Rust for new projects. No one with old C++ code is going to switch to these future hipster standards, let alone even C++14. I think this standard bloat is digging its own grave. It wi
