I get the opposite message, which is that programming tools and the process of programming are so bad, it's hard to get a computer to do a simple task for you without tearing your hair out, never mind building a UI. A better IDE (basi

My thoughts exactly. Why isn't this obvious? There's no invisible hand making wages match productivity. There's unions, and that's about it. If a new computer system makes my employees deliver twice as much value to m

Typical of newspaper columns about emotions, this article muddles along with a few anecdotes, a sprinkling of social science, and some facile conclusions. A book selected at random from the "self-help" section of your bookstore w

Can someone explain why worker productivity increases would ever enrich the worker? This sounds like a Golden Age fallacy. What forces in a capitalist system lead to paying workers more? Workers are not entitled to the value they create,

"Quality" here means the quality of your result. If you are learning to paint/sing/code, it means how good the painting/singing/code is. The advice is to not "worry" about the quality, in the sense

That's why this point isn't so related to the other two, because it's specific to the goal of getting better at something.

Oddly enough, according to the article, they specced the exact amount of blur first, and then figured out the pixel resolution required to look exactly like the original picture blurred by that amount, and then the JPEG quality factor they

There are actually three lessons here: * Momentum - To stick with something and finish it, you need to use momentum. Lacking momentum, projects languish. Quoting author Steven Pressfield: "Second only to habit, momentum is a writer’s

There's no clear value proposition given. What are we sacrificing Turing-completeness in order to gain? For example, one thing a programming language might gain by sacrificing Turing-completeness is that every program provably halts;

How does the output of the ClojureScript-compiler-in-ClojureScript compare to the real thing? Do you lose the Google Closure optimizations, and if so, does that mean it isn't a good idea to compile your web app using the ClojureScript

I don't associate "navigation transitions" with native apps. What native apps have navigation transitions? I think the iPod really popularized sliding screens and the like, and they spread to mobile. The feature for web bro

I wasn't very clear when I said, "They are just a different representation." What I meant was that modeling the universe as made out of conscious agents is not that different from modeling the universe as made out of atoms o

Compared to normal sheet music, this system mostly deletes cues. In normal sheet music, you have both the shape of the note and its rough position horizontally on the page as cues about the rhythm. Measure lines are removed in this system

There are some real howlers in here, such as when the author is quick to point out that the theory of natural selection in biological evolution assumes DNA exists even when you aren't looking at it, but we can patch this hole in the ar

TLDR, use Babel in "loose" mode and you'll be fine for pretty much all the ES6 syntax features (by which I exclude Maps, Sets, and generators). Most of the features listed are zero-overhead when transpiled this way. As usua

Frustratingly, we can't actually look at the React code he used, because it is Google proprietary code(?). But there are definitely slow and fast ways to take an array of elements and render it. Ideally, each element would be wrapped

Yes, this is exactly the hard/interesting part to implement. Facebook uses their own graph databases which lets you specify access control rules. You'd need something similar on top of SQL.

It would be more accurate to say, several SQL databases (that you may or may not have heard) of don't provide full ACID in the strongest sense, while MySQL, Postgres, and MS SQL Server all do if you pass the right flags. In a world pla

"Putting something on that will make you scream out to drivers like me is a fantastic thing." If Volvo understood cyclists better, they'd choose a quote like, "I'm a driver and I hate life paint. Who do you think

The productivity benefits of technology don't go to the workers. I'm not an economist, so I may have missed something, but isn't that obvious? If your job is to operate the copy machine at an office, and they buy a new machi

There's nothing inherently slow or problematic about composing code out of "pure functions." The implication that evaluating functions requires doing lambda calculus, which requires a weird runtime like Haskell, is pure FUD.

In that case, the parent could have asked, "Would it outrage you if someone slapped a GUI on your code and released it as freeware?" I think they didn't because even fewer readers would see the harm in that.

Lean Startup isn't primarily about building things, it's about the process of customer development. To make an analogy, before the advent of the scientific method, people would talk about theories, and maybe perform some experimen

I wouldn't say React isn't fast, but the OP is right, the claim that React is faster than the alternatives is basically just hype (or good marketing). Going back years to React's inception and public launch, everyone's c

I think quite a wide variety of app devs might find it more important to be able to, say, develop an app faster than have a snappy start-up time, especially if there's no fundamental limitation at play but just limitations of the curre

Telling mobile devs not to use web tech is an example of where this argument (request? demand?) falls down. There are a lot of advantages to using web tech (cross-platform, easier to develop, easier to push updates), and the result is not

Exactly. The TV makers seem rudderless and out-of-touch, so they should be thrilled Netflix is providing a roadmap to a better product.

When I write code and tests in JavaScript, typically the tests turn up a few typos and "brain-os" in the code (that don't keep it from parsing). Many or most of these would be caught by the type-checker in statically-typed l
