DBC was acquired by Kaplan back in 2014 [1]. Was this Kaplan's decision or DBC's? [1] https://www.wsj.com/articles/kaplan-to-buy-software-developm...

>32bit number indices not affecting length is crazy - I didn't know about that (I don't think I've knowingly dealt with an array that big). TypeScript thankfully prevents all of these errors except for the one I mentioned.

That's a fair point. Which language do you think does it better, or is there a library you like to use (eg. Haskell's scientific type)?

What do you mean by bizarre array semantics? Genuinely curious.

For == vs === use a linter, same as you would for warts in other languages. What's the issue with undefined - is it that you would use null instead? I don't feel a need for integer type, but maybe that's because I grew up on

By optionals I assume you mean null and undefined types, not optionals in the Scala or Swift sense.

On Chrome on iOS on iPhone 6, posts take too long to load, and having more than 3 gifs expanded at once crashes my browser. Also manual pagination instead of infinite scroll is a little annoying. Works very well otherwise.

Like what? TypeScript is careful to avoid a lot of JS's footguns (implicits, undefineds, etc.)

Updated, good catch.

That looks really nice. How big is it? And is the software it's running open source, and made to be extended?

The "Concepts" and "Debugging" sections are very strong signals in my experience. "Coding" is much less useful IMO, but this blog post is to help you practice the sorts of questions that are asked in practice,
522.
by bcherny 9y ago
"Concepts" is the 1st section..
523.
by bcherny 9y ago
If you have some good questions, I'd love to add them to the list.
524.
by bcherny 9y ago
You may have missed it, but that's question #10 under "Concepts": My website is slow. Walk me through diagnosing and fixing it. What are some performance optimizations people use, and when should they be used?

The specific functions you're implementing aren't important. What's important is that you can reason through a question, suggest possible algorithms, reason about their tradeoffs, write some code, and communicate all of that

by bcherny 9y ago
What are some examples? I'd be happy to add them.
527.
by bcherny 9y ago
That's what the "Concepts" section is for. Those questions are designed so that you can keep going deeper for people that know the concept. At some point everyone bottoms out, but it's a different point for everyone. Eg.

As a take home project then. Pressure isn't important, it's ability to reason through a problem and basic algorithm writing skill.

by bcherny 9y ago
It's a basic programming and communication skill. If someone doesn't know what it's called or what the syntax is that's fine. What's more important is the intuition: If I have program A: for (let i = 0; i <

In an interview setting, I'm sure you could hack something together and then improve it! Eg. an iterative Fibonacci is easy to reason about if you're not used to recursion. It's a good question for junior people because there

Aren't you confusing language with understanding? In computer terms (which I'm more familiar with) this is the difference between expressing a program in some language vs evaluating that program.

Nothing on the size of ABSL's vocabulary. Is there a linguistics notion of turing completeness? Ie. How do I know if a language is capable of expressing any possible concept ("program")? Is this even a meaningful question? Al
