NVIDIA has started integrating NVLink with the x86 CPU ecosystem. It's possible that NVLink will overcome CXL in this competition, just as CUDA once defeated OpenCL.

Show HN: Sci-parser, a parser for extract data from the unstructured output

sci-parser is designed for extract data from unstructured output of scientific software. I try to make it as easy as possible, performance is not a top priority for now.

New comment by link89 in "Huawei unveils its own programming language the "Cangjie""

link89 — Tue, 25 Jun 2024 01:27:33 +0000

This programming language reminds me of a lot of meta-language (ML) styles: function overloading based on pattern matching, immutable variables, and using `spawn` keyword for lightweight threads – a practice also employed by Erlang. Perhaps owing to Huawei's origins as a telecommunications equipment company, where many within the organization are familiar with Erlang, this new language exhibits numerous resemblances to Erlang.

I have tried both typescript and cue-lang to generate json configuration for a while and I have to say that I prefer typescript to cue-lang, especially after deno provides native support for typescript.

I don't think Turing complete or not matters a lot for a configuration language. What really matter are the toolchain support and the ability of express complex concept or relationships. Writing typescript with VsCode is a really pleasure and its type system is powerful enough to express complicate concepts. Besides typescript has mature packages systems which cue-lang is not ready yet.

With typescript you can easily do things like reading a json configuration via HTTP and override some varibles to generate the target json file you want, which would be hard to do the same thing with cue-lang.

As a conclusion, I don't think currently cue-lang would be a good solution for configuration generation. But I do believe it would get better in the future if the community keeps working on it.

Show HN: Dlna-cast, a command line tool to cast PC screen to DLNA devices

link89 — Mon, 14 Nov 2022 17:37:33 +0000

dlna-cat is a cross-platform command-line tool that casts screen and media file to remote DLNA device.

dlna-cast uses ffmpeg to capture screen and audio, then convert them into HLS streams which could be served by a simple HTTP server. The HLS url will be send to the selected device via uPnP protocol and then you can watch you screen on the remote device (smart TV, typically).

This tool is supposed to be cross-platform but currently I don't have a Linux or MacOS device at hand so it can only run on Windows now. It won't be hard to support other platforms though, as there are no platform specific dependencies.

HLS is chosen just because it is easy to implement. But the problem of HLS is its high latency (up to 5-10s or more) so it's definitely not for scenarios that require low latency (presentation for example). But as a trade-off the streaming quality exceeds a lot of software screen-casting solutions (Lebocast for example) that have been tested by myself, which make it pretty good to stream music or video playing from your PC to TV.

It turns your function or class into command line with one line of code. It's based on runtime type inspection so you don't even need to use decorator which most of the command line framework does (click for example).

Jenkins community has provided the offical jenkins-cli.jar but it is not very intuitive to use. So I just create a tiny wrapper for it to make it less noisy by dowlonading the jar packages and injecting user credential automatically. Thanks to the google fire library creating a command line tools nowadays is incredibly simple.
