It also has a significant amount of detail in subtle ways, some that can't really be appreciated until you try it. My go-to example of this is the "Attention Set," which came directly from Google's Critique. In short, it

The key part of the data model mismatch, one that could be solved, is that Git does not natively give you a way to refer to a commit by a "logical ID", one that remains stable under rebases and content rewrites, i.e. a unique iden

It doesn't manage a Git repository. It's a stateless proxy that sits in front of your existing Git repository. You just run it in front of your existing infrastructure. That's about it.

No, Git's object store was not designed to hold large binary blobs, and no implementation of Git in any language can change this. It's a reasonable request; I mean, Git doesn't even deal with "pretty small" binary f

PTP is part of the backbone of something like TrueTime. Meta uses their PTP infrastructure for a lot of the same basic fundamentals, including consistent read replicas, like Spanner does. PTP is a protocol for synchronizing the wall clock t

No, it wouldn't. Socketed DDR5 doesn't have the bandwidth necessary to feed a massive compute complex like the one in a modern graphics card.

This isn't a fundamental issue, but it is very, very boring.

Adding Copilot or GPT-4 autocomplete support to an editor is not hard. You can find 100 different projects on GitHub that do this which are all just calling OpenAI. It is vastly different in scope and design than porting native applications

Honestly, it's pretty cool in my experience; in VSCode everyone gets their own "client-side navigation" so while you are typing something, your coworker can go look up a function for you in another file, etc. Even though they

Yes, game development studios include their raw art and environment assets directly in source control, just like source code. That's because the source code and the assets for the game must go together and be synchronized. That also in

The Windows Git repository is only 300GB, that's basically childs' play when people are talking about "large repo scalability". Average game developer projects will be multiple terabytes per branch, with a very high numb

You can do it with QEMU using its emulation backend to emulate the entire x86 boot chain. It will be dozens (hundreds?) of times slower. Hypervisors work efficiently because they allow you to "nest" certain functions inside of oth

Hashlink seems to have the ambient concept of e.g. objects directly in its design and bytecode format, whereas e.g. wasm instead thinks of that in terms of "reference types" which represent existence of some opaque object. So ther

It could be done but it likely wouldn't perform well or be very useful (because the software surrounding the application also needs to exist.) The IR notably has a lot of indirections in the way e.g. function calls are represented (ind

Modern GPUs hide latency by scheduling tons of work and paying it back in throughput but this is very design sensitive and if you do it in an FPGA requires a ton of pipelining and design work. Which is often better spent just paying some sc

CXL doesn't really change anything except for the fact memory is coherent across the bus so you don't have to do your own protocol. "Core complex" is massively oversimplifying it but, generally speaking your accelerator

The use cases you write about are mostly constrained by design, not software. Configuration of SRAM based FPGAs is rather slow because it requires a scan chain to program each logical element and shift config bits into, and doing it faster

Yeah, the existing FPGA device subsystem has been pretty much worthless for upstream kernels for years now and the lack of a good userspace API is a big reason, so in practice everyone just bitbangs the bitstream over some QSPI interface an

There is initial electrostatic placement support for iCE40 and ECP5 in upstream nextpnr at this point, since a few months. But there hasn't been a stable release just yet.

Yes, see DREAMPlace -- "DREAMPlace: Deep Learning Toolkit-Enabled GPU Acceleration for Modern VLSI Placement".[1] The technique in particular rather reformulates VLSI placement in terms of a non-linear optimization problem. Which

You will probably like Jujutsu, which takes much inspiration from Mercurial, and even has a few prior Mercurial hackers working on it. It uses the Git data model underneath (so feel free to use GitHub), but has an entirely rebuilt UX and se

Scalar explicitly does not implement the virtualized filesystem the OP is referring to. The original Git VFS for Windows that Microsoft designed did in fact do this, but as your third link notes, Microsoft abandoned that in favor of Scalar&

There's nothing "esports" about wanting to avoid wallhacks/aimbots in games like Tarkov, Rust, or Destiny, which completely ruin the entire game for every player in the lobby in an instant. It has nothing to do with &quo

sccache should not be allowed in the sandbox, at least not just bolted on; realistically such cases are probably better handled in the long run by Recursive Nix, so that you can build new derivations inside of existing ones, and the results

It can cache at the level of any set of files, technically speaking (a single file, directory of files, and so on); so you could even use it as a Makefile replacement or something for example. But most people don't do that; the ecosyst

In the case of the Remote Execution/Cache API used by Bazel among others[1] at least, it's a bit more detailed. There's an "ActionCache" and an actual content-addressed cache that just stores blobs ("ContentAdd

Not just team members; if you make your cache publicly readable, contributors to e.g. your GitHub/GitLab/Whatever project can also use them and get really fast builds, the first time they try to contribute. So a remote cache is ni
