Not exactly related to Ruby on Rails, but why doesn’t there exist a way to run a Python TKinter app in the browser using WASM? I have a medium sized dependency-free TKinter program written in Python, and AFAIK there is no way to run it in t

In a society where the abuse of human labour was factored into the cost of the product, the 8-inch fab line would have been shut down, since the cost of the 8-inch wafers would now be prohibitive and not be competitive with the wafers from

We have a replacement for CUDA, it is called C++17 parallel algorithms. It has vendor support for running on the GPU by Intel, AMD and NVIDIA and will also run on all your cores on the CPU. It uses the GPU vendors compiler to convert your C

Having looked briefly at the code I still think C++17 parallel algorithms are more ergonomic compared to OpenMP: https://rocm.blogs.amd.com/software-tools-optimization/hipst...

GPGPU programming seems to be in a really good spot with the widespread adoption of C++17 parallel algorithms by GPU vendors. Now, I can just program against this API using standard C++ code, that interacts with CPU heap allocated memory, a

Which begs the question, if attractiveness is such a big predictor of success, why hasn’t everyone evolved to become very attractive? The evolutionary pressure for increased attractiveness should be very high, since it affects so many areas

That was why OP suggested to have 2 motors on each joint, going in opposite direction. The problem with this is that you now have twice the amount of motors.

Just use bsdtar, which will convert a tar archive to cpio: https://unix.stackexchange.com/a/581014 I have used it to convert docker images to Linux bootable initramfs archives for Rpi4.

If you are already using gRPC in your codebase, then you can define your enums with Protobuf, which does much of the same as the tool shown in this article.

Looks like great changes overall. Sadly they haven’t added columns to Dolphin, which is my only complaint from switching to KDE from macOS.

Not possible, unless you want to do it using an emulator and external memory. The lowest you can go for Linux is probably an ESP32: https://web.archive.org/web/20230515075935/http://wiki.osll.... https:

Well, if I found an unpatchable zero-click RCE exploit on an iPhone, then that would have a major effect on the stockprice when the news is announced. It definitely seems like it would be insider trading if i used that knowledge to do optio

Yeah, but regular package binaries get nuked pretty quickly to make space for new ones, especially on mirrors.

Sure, but how useful is that when you can’t install any packages, since the package repositories only host packages for supported versions. When a distro goes EOL, the package repositories typically move to the next supported version and de

Could someone enlighten me on how one goes about testing whether a particular crypto implementation is vulnerable to side-channel attacks? In high school I implemented a basic ECDH key exchange algorithm, which I compiled to WASM, and it c

Just because a compiler cannot prove whether or not a given set of C/C++ is safe, doesn’t mean that an expert in the language can’t write safe C++ and prove that it is actually safe.

Why not just tax stock buybacks the same or higher than regular profits? This would force companies to either increase R&D/CAPEX spending or lower prices.

I know, but the fact that people can’t even tolerate the inconvenience of an EV gives little hope for public transport, car sharing, bicycles etc.

I have done this, but for some reason Android SDK has to be weird, so you have to download the SDK seperately and then create a properties file in to root of the project with the path to the Android SDK. Everyone then also has to have their

Why is this better than an arena style allocator?

by mathiasgredal 3y ago
I get that there is a tradeoff with code density, although if you could have an encoding scheme or extended register mode to alleviate this. I was just thinking that if you have e.g a loop where you run out of registers, since you only have

Sure, but wouldn’t it make sense to extend the instruction set to allow the compiler to use these registers instead of reserving them for speculative / out-of-order execution? It was just a thought i had after watching a talk by a comp

by mathiasgredal 3y ago
I thought modern speculative cpu’s had way more registers than you can normally access. Why does it reserve these registers for speculative execution instead of exposing them to the program if it needs them?

Does anyone know if there exists a tool that can convert tarballs to filesystems and back. I know you can make a loopback device, but it can be pretty hard/impossible to do inside a container, and often requires special flags and privi
