With Unix sockets you can even have in-order datagram semantics, which I think is just neat!

lxtxon Ask HN: Getting back to C++ and looking for ideas

Rather go with C, or as was pointed out in this thread, Orthodox C++.

Less time being bogged down in the quagmire of C++ "features".

lxtxon Why Clojure? (2018)

Thanks! Although I don't agree with all of the points, it was a good read.

lxtxon Why Clojure? (2018)

Language intricacies aside, is there a reason to use Clojure over Elixir, Erlang? Genuinely curious what JVM has to offer vs BEAM / OTP if you're going to use dynamic languages.

lxtxon GitHub Readme Templates

What's with the proliferation of emojispeak?

lxtxon Ask HN: Did you take any fresh MOOCs as of 2020?

Not sure if it's a new one, but I'm liking https://www.coursera.org/learn/financial-markets-global thus far.

lxtxon QuakeJS – A Quake Port to JavaScript with Emscripten

Sadly no, but I don't think there's much of a ping difference on a good network. With WebRTC (datachannels in UDP mode) you just get the benefits of UDP (or lack thereof :)).

lxtxon QuakeJS – A Quake Port to JavaScript with Emscripten

Basically yes, a custom datachannel implementation. Haven't updated it lately, but it's up at https://github.com/seemk/WebUDP

lxtxon QuakeJS – A Quake Port to JavaScript with Emscripten

Only played it with my friends, don't think a map ever exceeded 10 players. So I can't say much about scaling - although it was a client-server model over UDP and not peer to peer networking.

lxtxon QuakeJS – A Quake Port to JavaScript with Emscripten

If I remember right, this one is over WebSockets and the server is compiled to js as well. My version had a native server and browser clients.

lxtxon QuakeJS – A Quake Port to JavaScript with Emscripten

Quake's source code is very hackable. I forked ioquake3 for a personal project and it was surprisingly easy to add WebRTC support to the C codebase, so you could play it in your browser over WebRTC :)

lxtxon A restaurant owner who asked for 1-star Yelp reviews

If I remember correctly, there was no matching system in BW.

lxtxon OpenTTD Compiled to WebAssembly

The forked ioquake3 is available at https://github.com/seemk/ioq3

However it's not trivial to get it working at the moment, will hopefully soon come back to this project and finish it :D

lxtxon OpenTTD Compiled to WebAssembly

You can. I've used WebRTC for multiplayer support in Quake 3 compiled to WebAssembly.

lxtxon Farewell, Google Maps

You can also prerender the tiles on a powerful machine and host them on a cheap instance (assuming you don't need very large regions). A while ago I created an OSM server (https://github.com/seemk/TileSweep) to do this for me, you can select regions you want to render via a polygon and you get a SQLite database of the tiles. It can also run as an alternative for mod_tile + renderd.

I rendered all of Estonia from zoom levels 0 to 18 (~16.5M tiles) which is around 20GB and host the tiles on a cheap DigitalOcean instance.

lxtxon Clang runs in the browser and compiles C++ to WebAssembly

I've written a library for that purpose [1]. It's not ideal, but I guess it's as close as you can get to UDP in a browser without using extensions.

lxtxon Show HN: Airmash – Multiplayer Missile Warfare HTML5 Game

It is not entirely P2P, a server can act as a "peer" for all clients and handle the connections itself.

lxtxon LibHTTP: Open Source HTTP Library in C

libh2o does not require libuv, it has its own event loop. libuv is optional.

lxtxon Estonia blocks electronic ID cards over identity-theft risk

Not really, I can still use my mobile ID just fine. Not even in a hurry to get my certificates updated.

lxtxon Show HN: Vehicle Detection – using machine learning and computer vision

Totally agree with your point on HOG + SVM, I think it is obsoleted by convolutional neural networks.

I wrote a realtime human detection library [1] for a robotics project that used HOG + a simple neural net for classification. While it worked okay, I wasn't happy with the precision (around 90%) and decided to try out a simple convnet from Torch (doing the classication on depth images instead of HOG descriptors). The Torch version was slightly slower on a CPU, but both the precision and recall jumped up drastically.

lxtxon Building multiplayer games with Socket.io and HTML5 Canvas

Definitely a bit weird. Where are you located? The echo demo server is hosted in the Netherlands. That's how the round trip histogram looks for me in Estonia: https://i.imgur.com/iBoqwe4.png I'll take a look later if there's any noticeable delays caused by the server.

lxtxon The Need for Web UDP

Posted this recently in another thread, but maybe someone will find https://github.com/seemk/WebUdp useful as there have been many WebRTC threads lately. It's a WebRTC DataChannel server implementation for out of order, unreliable UDP traffic for browsers that has built-in SDP signaling and STUN.

lxtxon A real world guide to WebRTC

You might want to check out the project I've been working on: https://github.com/seemk/WebUdp

It's a minimal WebRTC server implementation (SDP, STUN, SCTP, DTLS and everything else) contained in a single library. Note that it only implements a subset of the specs to get it working and probably still is buggy (experimental!) as I'm developing it while working on another project that uses it.

lxtxon HPE unveils The Machine, a single-memory computer with 160 terabytes of memory

Wasn't the Machine supposed to be a memristor computer? Did they ditch the project?
