Viewing profile — RX14

It's had consistent contributions for 5 years now, with the latest being about a month ago.

Hunting in modern rail vehicles is largely a solved problem using axle yaw dampers and other systems. I struggle to see why BART doesnt use a standard wheel profile and buy from a …

There are some trains which use independent wheels, but they need complicated mechanical centering mechanisms to replace the self-centering effect, and these are more expensive to …

Long-distance trains in the UK manage about the same, with 200km/h max, but for more of the track (and higher accel/decel)

The -ls flag to find prints the same as ls

I would greatly greatly appreciate an effort to benchmark builds without optimizations too. We've seen some LLVM-related slowdowns in Crystal, and --release compile times are far l…

DBMSes always keep their database in the file system in a consistent state to be able to recover from system crashes. Taking a file system snapshot is equivalent to pulling the pow…

It seems a lot of people have these stories, and then people like me and OP who have had btrfs survive the most fucked up situations (I've had a btrfs nas built on "random drives I…

My secondary motive is that I'm a girl :) I certainly wasn't much more than sleepy and wanting to break the stereotypes on that particular expression when I wrote it.

First class? About a girl-year or two I'd guess. Fully usable? About half that.

If you reach out to manas directly, I'm sure they will be happy to have a sponsor for a particular feature.

Yes, you can do the same optimizations in Crystal, and Nim. Someone should write these and post the code for comparison.

Hopefully wasm's gc proposals will be implemented and get LLVM support, allowing languages like Crystal to sanely support wasm.

Yes, we do so for more complex formats like YAML and XML. However, for JSON, reimplementing is worth it for binary portability.

The basic foundations of a Windows port are already in place for Crystal, merged into master. In fact you can can already cross-compile a "Hello World" on Windows. This means the p…

Unfortunately there's no concrete timeline, it's being worked on on-and-off by the community. If you have free time, or free money, it'd be a great help to the effort.

JSON is actually implemented entirely in Crystal for Crystal, I'm pretty sure it's the same for Nim too. For a language which claims to be fast, having to use a C-based JSON parser…

The JSON code is written in a way which forces the whole object to be loaded into memory - both in Nim and Crystal. It would be interesting to compare code clarity and benchmarks f…

> We’ve been waiting for years. I know, and it's unfortunate that there's not been time to work on this. I don't think people understand how small a language like Crystal is though…

Nice article! There's one small error, where the article says "With Nim, we were also able to link both the Nim and C files into the same executable, which Crystal sadly cannot do.…

We used to be a pretty nice purple, and I kinda miss that.

It's unique selling point is union types as a part of the type system, with whole-program type inference and flow typing. This has never been done before (as far as I am aware), an…

It's certainly decentralized, just federated instead of distributed. And yeah, it sucks as a protocol (but not that badly, the standard is just weak like everything else the w3c pr…

Matrix is a fundamentally broken protocol held up by the prowess of it's UI design team.

A long poll connection (i.e., a TCP connection not sending packets) uses exactly 0 joules of battery until something is sent.
