Kind of, but Jobs was a "product guy," not just a manager type.

If I had time today, I would totally put this up on a github repo. It might not be easy for one person to keep this up, but with pull requests + a github.io domain, we could keep this good work going. I'll be happy to help with getting

I hear you. What would you call that, решебник/сборник? I'm planning to make an exercise generator framework with print(.tex) and web(.html) backends. The early khan-academy exercise framework was pretty awesome since it could gen

Geometry and art are definitely related, and you need to know the equations to generate the drawings. It's amazing how much possibilities are open once you know some basic high school math (see my book https://gum.co/no

That's a good point. A bullshitter in a middle management role can serve to shield developers from all the bullshit that comes from above. That's a very useful contribution—so the productive devs can focus on working rather than a

Stick with it and don't despair. The job search space is totally non-sense these days. Don't let the rejections bring you down—most recruiters don't know what they're doing. What are your expectations? From my experience

Do you mean the title or the content of the book? I'm asking because I thought the main LA content is rather clean—the first book on MATH&PHYS had much more of the "juvenile" stuff. Also is bullshit really that bad? I nev

Not yet, but I'll be happy to get a wallet going to make this happen. Any recommendation for a good bitcoin wallet provider? I don't care about mobile app: web-only is good enough for me. Ideally fully offline.

Anyone interested in learning quantum mechanics should first learn/review their linear algebra. Understanding quantum states and quantum measurements is really not that complicated once you're comfortable with vectors and matrices

It's not a question of possibility, but rather speedup. The three "flagship" algos are for unstructured search[1] (not clear if really useful), factoring[2] (useful to crack public key crypto), and more recently there is a re

I like to print things out because it makes them very concrete. I can literally see the whole code base I need to become familiar with. It's very useful for working in legacy code bases, or when trying to reverse engineer what is act

Git is pretty difficult to learn, but the customizations it allows are amazing. To get a "fancy oneline log" output, add the following to your `~/.gitconfig` [alias] ll = log --graph --oneline --decorate --date

I've used both extensively and I think they're virtually identical. Mercurial is a bit nicer because it's written in Python, but git has github going for it. In my experience, once you get into more complicated commands like

The main idea in softcover is to use (a restricted subset of) LaTeX as the "main" representation, which then gets converted to html + MathJaX using tralics (a latex-to-xml converter) and lots of custom pre-processing, and post-pro

I find it difficult to separate the "teaching practices" from the "teaching content." Wouldn't the approach the teachers take be dictated by the textbooks they're using? Even in primary school, a good lesson wo

I can't argue with the music analogy—it's a very strong point. My view is that pursuing fluency in the basic arithmetic skills as an intermediate goal towards higher understanding might not be a necessary step. Assuming the person

Nice illustration of the "row picture" of matrix multiplication. The "column picture" is equally important. This intro lecture by Prof. Strang is a really good lesson on that: https://ocw.mit.edu/courses
