I recently built out training and inference at a FinTech (for fraud and risk) using Elixir and tried this very approach… We’re now using Python for training and forking Ortex (ONNX) for inference. The ecosystem just isn’t there, especially

Amazing. Do you know if Telkom offered ISDN around ‘95 thru to ‘01? My parents had “two lines” back then so we could always have access to the Internet, even while talking on the phone. I recall, vaguely, using dial up but we may have had a

You can LISTEN/NOTIFY. Or you can use logical replication and a custom subscriber.[1] Supabase uses the latter.[2] [1]: https://www.postgresql.org/docs/current/logical-replication.... [2]: https://

There’s some articles floating around that touch on the idea. Bitsquid comes to mind. [1] To give a slightly more detailed description, you allocate two arrays of the extents. One is the dense array of whatever type, say T, and the other is

At a quick glance, this is very close. However, the proposal goes through several contortions to maintain pointer stability. If you preallocate sufficient storage for your worst case (which can be unmapped virtual memory) then it makes impl

A similar data-structure that is also very useful uses sparse-dense arrays but encodes a free-list in the unused memory. It's an ideal data structure if your access patterns are sporadic reads/writes bookmarked by frequent complet

This echos my experiences, especially with the move to “live services” model for games. Often the teams working on the services for multiplayer games are very small so it’s all about leverage. They’re also embedded within a culture that doe

Really cool! I've been meaning to implement SGP4 from scratch as a learning exercise. What I found really interesting is how the USAF/NORAD tracks and reports objects in LEO: they publish Two-line Element Sets (TLEs), which are a

Windows bundles software decoders (for H.264 and H.265) that are available through MFT and DXVA.[1][2] Chromium leverages both already.[3] It's also a low effort way to support hardware-accelerated decoding as vendors (Intel, AMD, NVID

Worth noting that you pass in data in a proprietary binary format. [1] I've done it, not out of performance concerns, but because transcoding between proprietary binary formats with types is a lot saner than the alternative. [1]: http

Hi! I really enjoy working on things that operate at scale (in users or data) or provide a lot of leverage for my teammates. I'm open to a lot of roles. Most recently I was the sole data engineer for several million MAU video game. (I&

Latency kills: memory latency, network latency, and storage latency. In that order.

I love lifting for exactly this reason. It's meditative.

I disagree. Near realtime (say sub 1-minute) feeds can be leveraged to extract a lot of value out of the data you're collecting. Perhaps maybe not for your typical SaaS startup, but for free-to-play video games you end up leaving so mu

Logistics is your force multiplier. Sacrificing the (excessive) performance of 7.62 to improve the rounds you can field is well worth it. That said, 5.56 still holds up well in CQB, provided you have a sufficiently long barrel and a bullet

It takes ~20 LOC to setup scaleable asynchronous I/O w/ IOCP. It's been like that since 1996. So that's the benchmark as far as I'm concerned.

It's a pretty useful attack vector since you can get an arbitrary program to load your payload under certain circumstances, so you don't even need malicious code running if you can find a vulnerable target. cough SharePoint cou

I learned something a few days ago that made me both laugh and cry: LoadLibraryA will happily load a DLL from WebDAV through a UNC path. Something like \\example.com@80\path\to\payload.dll. It goes without saying that this has been abused b

As someone in the midst of building a game in C for 7 platforms, with WebAssembly being one of them, my main disappointment is with the lack of coroutines (or lack of control over the stack to implement them.) It hinders how wide my engine

I don't get the hate. I can reason about asyncio code without fuss and the throughput/latency impact is worth it. My only pain point is the derth of libraries. There are few if any palatable libraries that provide the powerful abs

I recently used RCTEs in a production environment to operate on reasonably large graphs. We eventually moved to an in memory solution built on top of ETS for various reasons, but performance was not a deciding factor (at least as much as yo
