I've been using the Rust playground a lot this week, and I wish it had a history feature - I often closed a tab and later wished I could get the code back. I'm thinking about trying to contribute a localStorage-based history mecha

I'm a big fan of static typing, including sum types. But can someone explain to me what's so great here? The highlight of the article is having a unique Action sum type instead of a myriad of separate functions. But the action sti

In the short term you are right. However the legal authority to enforce censorship will be established. All it will take is for the Department of Home Affairs to become less incompetent and suddenly things will become very serious. I think

Go's philosophy strikes me more as "when many solutions are available, pick the most practical one". In this case, an alternative solution (among others) would be to always allocate a new array when calling `append`. This sol

I use `const` instead of `var` almost everywhere and use `let` in the few cases that actually require reassignment.

The T-Mobile plan only offers you international data if you pass a credit check. I applied twice, once by phone and once in-person at a store. I got rejected twice. I have excellent credit and suspect the issue is something stupid like my f

A parent post was criticized for being too general, so I'll be extremely specific: cheese from the Whole Foods located at Park Place, San Mateo, California is crap compared to cheese from the cheese shop located on Rue Saint-Hélier, Re

Yeah, Babel and the Babel team is great. I got very suspicious of the project after my first experience with it broke perfectly valid code, but after reporting the issue and then another and having them fix it almost immediately they won my

You have a very valid point regarding bugs. Transpiler bugs definitely happen. When I first tried using Babel - still named 6to5 then - instead of Traceur, it immediately broke my code because of an incorrect TCO implementation in Babel. Ba

Have you actually tried TypeScript? It feels just like writing JavaScript, but with a thin layer of type annotations that bring you the familiar advantages of static typing. It seems to me that JavaScript haters would be better off moving t

From the article: "A GC is necessary to provide memory safety guarantees. [...] For any programs that need heap-style memory allocations, if you want to guarantee memory safety, you need a GC." The main clame to fame of Rust i

Why do all threads about Go seem to be full of people who cannot live without generics? Snark aside, feature X is rarely absolutely needed (you can replace your generics by some boilerplate; you can use grep instead of your text editor to p

Yes, the ES6 `length` function would return 0 for [undefined, 2, 3]. I hope it was only used as an example in the article and nobody is planning to really use this. (Edit: see sibling comment; the article is already aware of this issue.) An

I've been pondering a few style questions recently: 1. When to use 'function' vs '=>'? Leaving aside hoisting and handling of 'this', 'function' and '=>' are usually interchange

Yes: const description = ({name: {first, last}, occupation}) => `${first} is a ${occupation}`; Edit: just noticed that `last` is not used, so we can remove it from the destructuring: const description = ({name: {first}, oc

Yes, "let" is better than "var". I could also have used a fat arrow in the forEach(). But my point was to list iteration variations, so outside of that I wrote traditional ES5. This illustrates the issue though. "va

My biggest issue with the recent additions to the language is that there's now a thousand different ways to do the same thing. Iteration: for (var i = 0; i < y.length; i++) { ... } for (var x in y) { ... } for (var x of y) {

You make it sound like what matters most is not actually studying CS but getting a CS degree . Is there something special about getting a degree that would cause a programmer to "never be quite as strong" if they studied CS but

You're right, it doesn't make sense to compare a smaller city surrounded by farmland with one of the biggest urban sprawls in the USA. I posted this under the strong influence of nostalgia :)

What bothers me with suburban living in the US is that you give away the convenience of the city and all you get back is a backyard barely big enough for a barbecue. Here's the house where I grew up in France: http://i.imgur

Only a subset of rewrites are redirects. A common usecase for rewrites is to change the request URI to make it match another location block in your config, but without returning 301 or 302 or any other redirect code to the client.
