Are there any plans to actually make a 4.0 ever? I remember hearing a few years ago that after the transition to 3.0, the core devs kind of didn't want to repeat that mess ever again. That said, even if it does happen, I highly doubt t

CI: I changed a pipeline at work from pip and pipx to uv, it saved 3 minutes on a 7 minute pipeline. Given how oversubscribed our runners are, anything saving time is a big help. It is also really nice when working interactivly to have snap

Had to replace the NVME SSD in my Thinkpad a few years after it went out of warranty (that Thinkpad has a motherboard replacement on warranty as well). Needed to replace the fan in an older Thinkpad after 9 years. Unfortunately the quality

> Typically no... which is another way of saying occasionally yes. You might be able to avoid generating panic handling landing pads if you know that a function does not call panic (transitively). Inlining and LTO often help, but there i

Rust does. You have editions to do breaking changes at the surface level. But that is per crate (library) and you can mix and match crates with different editions freely. Thry do reserve the right to do breaking changes for security fixes,

Yes that is annoying, but I don't know of any mainstream systems language that does. C and C++ can also have allocations anywhere, and C++ have exceptions. And those are really the only competitors to Rust for what I do (hard realtime

Own and uninit have been in discussions wrt in place construction. The Rust in the Linux kernel project seems to be the motivating use case for this that really got the effort going recently.

I feel like other languages also have the issue of complexity and changing over time. I doubt I know all of C++ post C++14 for example (even though that is my day job). Keeping up with all the things they throw into the standard library of

Many of the things like "&own" are ideas being discussed, they don't exist in the language yet. As far as I know only &, &mut and raw pointers (mut and const) exist in stable rust at this point. The standard libra

Your suggestion confuses latency and throughput. So it isn't correct. For example, a modern CPU will be able to execute other instructions while waiting for a cache miss, and will also be able to have multiple cache loads in flight at

From a societal view it is worse when everything is down at once. Leads to a less resilient society: It is not great if I can't buy essentials from one store because their payment system is down (this happened to one super market chain

To the list of profiling tools I would like to add KDAB Hotspot and KDE Heaptrack. The former, hotspot, is a visualiser for perf data, and it deals ok with truly massive files that made perfetto and similar just big down. It also supports v

Channels and RCU can often be better for performance as well . I have run into scaling issues due to contention way too many times. Sometimes just because two things were in different parts of the same cache line. Sharing as little mutable

Python is big in the sense that your wasm bundle with the CPython runtime and a bunch of the standard library are going to be several MB most likely. Just libpython.so in my system is 8.7 MB for example. The standard library is an additiona

Agreed, I would like to be able to specify vase mode as a height range modifier in the slicer, so I could shift back to non-vase mode near the top. If you want full control though, you might want to look at https://github.com&#

I saw a programatic Web cad tool before, took a moment to find it (and along the way I found a few others). Caveat: of these I have only used Onshape, and I tend to use it via the graphical interface. - First up Onshape is web based, but is

Ah, I have a Mk3.9s, and definitely don't need more than one printer. I looked at the model on printables, and have a followup question: why does the slit go all the way through? You can make the first few layers print normal and solid

That is rather ambitious. I don't know how you prefer CAD, but if you don't like parametric CAD (Fusion, Onshape, FreeCAD, etc), nor sculpting (Blender, and various other artistic things) there is also code based CAD such as OpenS

(Original author of the blog post here.) That is a neat model. It seems like unlike printables, makersworld doesn't have a 3D preview on the website (or maybe you need to be logged in, or use an app or something)? As I have a Prusa pri

Yes, fuzzy skin does that, in order to create a rough texture. But your idea won't be perfectly conforming to the original shape either, the physics of molten plastic means you will likely get unevenness still. You could consider writi

I like this idea. Hiding the seam in a crack or sharp corner (convex or concave) is already a thing, and your idea builds on that. I'm also curious what it would do for part strength. If you offset the zig-zags from layer to layer it w

(Original author of the blog post here.) That is a neat design. From what I can tell though, the split base/top is overly complex. You can simply set (in PrusaSlicer at least) the number of layers to print normally before switching to

Original author here. Thanks for the feedback. I always find it hard to determine what audience is appropriate for what I write. In this case I specifically didn't want to spend time on explaining what I consider basic terminology, and
