Where all existing Rust books fall short is that they are not Rust books.
They are books on building software with Cargo framework.
A great "Understanding Rust" book would based only on using rustc for all examples, and in the context of that book e.g. GNU make could be used to orchestrate the builds.
Using Cargo is obviously fine but it is in the way of in-depth understanding of the language.
This also means that I really do not recommend any of the books written about Rust because they are all as useful as the Rust documentation, i.e. not that useful.
#rust #cargo

1. My calendar for 2025.
2. My security tip for 2025: use pen and paper for what it works. That info does not leak. I still plan and draft with a notebook (having a grid) and pencil.

Today I'm going to:
1. Install Windows and wipe my Fedora.
2. Install NVIDIA drivers.
3. Redeem the code for "Indiana Jones: The Great Circle" and check that I get it to Steam.
4. Install Fedora and wipe Windows.
Wondering why FSF had a campaign based on lies about TPM chips, and does not have one on NVIDIA being DRM ;-)

If you've ever wondered how to debug custom targets outside of cargo environment, here's an example of that:
https://github.com/paritytech/polkavm/issues/208#issuecomment-2544941559
I.e. situation where you just want to check what the compiler emits.
#rust #cargo

Not forgotten and not discontinued:
https://github.com/umlaeute/v4l2loopback/issues/268#issuecomment-2541605102
Just a slow process and busy at work before holidays ;-)
This is pretty typical for OOT drivers really. Bad architecture choices kind of accumulate because no one dares to make any actual changes to what is already there.
Probably would happen to me too if I was doing OOT so not blaming anyone, just saying how it is ;-)

I wonder does SDL3 have anything like baseview [1] for writing plugin UI's?

Three months in a company after this month. Three PR's in that time. The last one is almost finished: https://github.com/paritytech/polkadot-sdk/pull/6533
Could have performed better but at least all wen right and RISC-V based smart contract moved from PoC to experimental feature in the SDK.
After #6533 next up is to further refine DWARF parser in the PolkaVM.
People have different feelings and thoughts on blockchains but I do enjoy the most is that the whole ecosystem is so unfinished :-) Lot's of cool stuff is still waiting for a trophy collector.

Nice write up about Deluxe Paint:
https://www.datagubbe.se/dpaint/
Also in the later years Deluxe Paint Animation on PC was cool.

Willow performed a standard benchmark computation in under five minutes that would take one of today’s fastest supercomputers 10 septillion (that is, 10^25) years — a number that vastly exceeds the age of the Universe.

I was wondering why rust-analyzer does random hickups and switching to lld finally fixed it. The choice of linker inherits from matching Rust environment of macOS, which does use LLVM ld, and never experienced similar glitches. This even happened sometimes with 9950X desktop.
So for any Rust installation in Linux I'd first and foremost always add this to .cargo/config.toml before anything else:
[target.x86_64-unknown-linux-gnu]
linker = "clang"
rustflags = ["-C", "link-arg=-fuse-ld=/usr/bin/lld"]
Installation:
1. In Fedora: dnf install lld
2. In Debian: apt install lld
AFAIK, by de-facto it probably uses GNU ld, and also some flashier newer ones do not provide glitch-free result with rust-analyzer (i.e. mold and wild).
#rust #llvm
