Check out WSL. I’m of the opinion it was created specifically for web devs in your situation. After all, what really is a MacBook to a web dev besides a off-the-shelf reliable laptop with a Unix terminal?

I had some code that tried to stay 16x8bit, but would occasionally _mm_unpacklo_epi8, _mm_unpackhi_epi8 to 2 8x16bit vectors to keep precise intermediate results during some fixed-point math. Writing it out like that, it sounds like it shou

I only played with ISPC a little bit. What I found is that it is really great if you need to write a large volume of SIMD code and that code sticks to one lane size. Like, 4 32-bit floats or ints. But, if you want switch mid-stream to 8 sho

I heard a story recently about that being exploited as an attack. Attackers knew some site used some DB that used a specific hash and items that hash to the same value end up in a linked list. So, the submitted a ton of user data that all

I’ve used it in many games. It’s a simple, but powerful language that uses basically two features (functions and hashmaps) to implement everything. Ex: script files are implicitly functions. Global variables are in a hashmap. Semantically

The Roblox team is making a new Lua interpreter (not JIT) from scratch with a focus on performance. Don’t think it’ll be open source though.

Well, I know it requires elements to be laid out in the order they are declared, but it is allowed to put gaps between items for alignment. I guess a compiler could insert a 16-byte gap and do whatever it wants in there. I don't expe

It doesn’t sound like you are mentally modeling cache misses correctly. Any access to any array (dense or holey) that isn’t already in cache will result in a miss. A goal is to minimize misses by taking advantage of locality and prefetchin

Compilers are extremely limited in how they are allowed to change data layout on your behalf. In C/C++ there’s: per-platform integer sizes (which are easily and usually forced to be consistent), padding between members of structs, alig

Showing VR users awkwardly ignoring friends who are right next to them does run face-first into a talking point I've heard repeatedly from people who reject VR out of hand. While, I agree with you 100% that it was a poor choice of them

Thanks! Now, can anyone ELI5 the high-level goal of this exception? At a glance it looks like GPL2 folks are still not happy with the patent provisions of Apache 2.0 and this is added to appease them.

Tried the XR-1 at SVVR. It's very impressive. The camera is very high rez and low latency. If I look for something to complain about, the colors are not very rich, it doesn't handle glaring light well, and your perspective is sh

Immutable data structures are great for undo-redo. Sean Parent has a conference video out there about how undo in Photoshop is implemented by breaking the image into tiles then making a list of the history of each tile. This allows the “His

I am a very poor student of mindfulness meditation. But, one of the big benefits I do recognize is practicing this strategy. Have you ever watched someone screw up in slow motion? Where you sat back and said “Duuuuude... don’t go there!”

Seconded. The goal of meditation is not to succeed at being free of intruding thoughts. It is to practice noticing intruding thoughts and bringing your mind back to focus. Having an intruding thought while meditating is not a failure any

I expect it’s that skim has the same amount of lactose sugar. But, with less fat you’ll likely drink more of it before being satisfied. Everyone should try lactose-free milk just once just to see how very sweet it is. It has the same sugar
