My favorite FoundationDB layer is per-user SQLite databases: https://github.com/losfair/mvsqlite It's hard to tell if it's running in production, but the author works at Deno!

I was referring to both the lower memory bandwidth and lower FLOPs. The GPU can just do… more at once? For now. Or is that changing? I had also assumed that loading a chunk from the cache was not free because I’ve seen cache eviction on my

Oh, yes, I misread! It’s great for that

It essentially never makes sense to run on the CPU and you will only ever see enthusiasts doing it. Yes, hammering the GPU too hard can affect the display server, but no, switching to the CPU is not a good alternative

My understanding is that model throughput is fundamentally limited at some point by the fact that the ANE is less wide than the GPU. At that point, the ANE loses because you have to split the model into chunks and only one fits at a time.

Yeah, that’s a bummer. It does appear to be in nixpkgs, though: nix-shell -p sqlite-rsync

SQLite has an official tool for this, fwiw: https://www.sqlite.org/rsync.html It works at the page level: > The protocol is for the replica to send a cryptographic hash of each of its pages over to the origin side, then

SQLite tosses out the SQL once it is parsed into bytecode. Using text is just going to take longer, even though I’m sure it works great. You can modify the database before vacuuming by making a new in-memory database, copying selected table

I'd recommend folks watch the video – it's fascinating. The truck gets OTA updates through your phone and not some LTE modem. It doesn't have one. They moved all car management including OBD-like functionality to the phone,

Attesting that a closed source device meets arbitrary closed source standards is a necessary evil. One real world problem is that some existing systems are built relying on the integrity of the components within, i.e. BART in the bay area r

Better security! A malicious actor only needs to change a few bytes in either the source or binary of OpenSSL to break it entirely (i.e. disable certificate checking). Reproducible builds remove a single point of failure for authenticating

Doesn’t even have to involve project managers. Just someone who isn’t an enthusiast and/or doesn’t care at the helm.

Are the protocols compatible enough such that someone could proxy JMAP to CalDAV?

by conradev 2y ago
Totally. The march continues with userspace drivers and exclaves[1]. I think it's fair to say that security is a big driver for their kernel evolution. [1] https://www.theregister.com/2025/03/08/kernel_sa

The routing decision that an MoE model makes increases its chances of success by constraining its future paths.

That makes total sense! Beyond the efficiency of no servers, the other aspect of CBS that is appealing to me is its simplicity. Graft introduces a lot of new concepts, and while they might be necessary to achieve the more ambitious goals, i

The Secure Enclave is nowhere between the AP and the Broadcom chip. The application processor has an IOMMU and the kernel uses it to restrict what the Broadcom chip has access to, and the linked article series discusses exploiting the IOMMU

Labels in public health are absolutely problematic for exactly that reason. But I will also say that ADHD, if you have it, is an essential part of your identity regardless of your awareness of the label.

The maintainer would just change the sandboxing constraints to weaken the software. Just like they did in the first place. You can try to make obfuscation difficult, but it’s always possible.
