Enforcement of this particular policy is one of the things I dislike most about HN. The current title is awful. It gives no information that the URL itself does not and doesn't explain why I'd care about the contents now given I

So in looking at the Kangax tables when the next Safari comes out, it looks like all major desktop browsers will have support of the big ticket ES6 features (arrow functions, destructuring, default params, Map/Set/WeakMap, Proxies

The standard response from the Rust team is that Rust should match or beat non-SIMD C++ performance and if it doesn't, you should file a bug. Note: The first thing anybody will ask when you complain about Rust being slow is whether you

The issue with Vim is that the editor has several hundred/thousand idioms and everybody uses a different subset. As an example, most people delete words with `dw` while I usually use `dt<space>` because the t/f motions gener

Code is not based on atom, it's based on Electron, which is the runtime (node+webkit without the UI chrome). VSCode has lower typing latency and a more considered system for building / debugging / code completion. Atom has a

I learned vim 15 years ago because I saw its history and realized that if I learned vim, I'd never need to learn another editor's key commands. If you're not going to be programming, spending 20ish hours learning the intricac

As a heads up, node will pick up destructuring the next time they bump v8. That's the last feature keeping me on Babel so I expect adoption to be fairly quick.

My biggest annoyance with Lambda is that it's stuck on node 0.10.x. How are language versions handled on Azure Functions?

It'd be related to inlining a function since size is a common rule there. Some searching turns up this[1] article on crankshaft from three years ago, which lists the restrictions as ">600 source characters including whitespace

More or less. There was a minor parser combinator arms race in the Rust community a few months ago using http parsing as the benchmark and my takeaway (only half paid attention, I haven't needed to write a parser) was that they got to

I compile Servo twice per week or so to check out the progress. It's really not ready to go as a daily browser. You can load pages, they're recognizable but generally not fully correct, the form input fields are rudimentary, and i

This is true unless you're using cljs-datetime. The library's use of goog.date objects under the hood means that storing one in your state tree invalidates the fast equality checks that everything in the clojurescript space is ass

No more odd than using Java. There's the huge difference in libraries and tooling but I don't think any inherent feature of Rust makes it less suitable for web backends than Java. I wouldn't pitch this project at work today b
