I will be impressed when they release the weights for these and older models as open source. Until then, this is not that interesting.

If I were to ask most people I know offline, I suspect only a small number of them would know what a minisplit unit is. For most people, A/C is like plumbing. They do not think abo…

Minisplit AC units are not very popular in the US. The US mainly uses either central air conditioning units or all in one AC units that are designed to be installed in a window. Th…

If you need R410A refrigerant, the high costs are due to government regulations causing the shortage. I very much hope that the heat pump I had installed 2 years ago does not leak.…

ZFS has a very nice set of macros that work very well: https://github.com/openzfs/zfs/blob/master/include/os/freebs... See P2PHRASE() and friends. They were inherited from OpenSola…

It uses multiple non-standard extensions to C. A strictly standards conformant compiler would refuse to compile it.

There is no statement about the efficiency of the motor itself. If the energy conversion efficiency is low, then the weight savings will not matter and the car will have even less …

This depends on the PIO in the RP2040/RP2350. As far as I know, that is an innovation exclusive to the Raspberry Pi company, so it would not be possible to do this on another micro…

This would be a great starting point to make a USB Ethernet NIC if someone were inclined to do it. It could even have a very practical use if it were made to impersonate a USB Ethe…

I remember hearing about people doing that around the time that windows 98 was still current. It was really impressive. At the time, the idea of an operating system using a gigabyt…

That is even smaller than minimal versions of Windows XP: https://archive.org/details/smallest-windows-xp-rtm-sp-0 I assume the minimal version of Windows XP still has components t…

If you install the right software, Windows XP reportedly can run most Windows 7 software too: https://github.com/shorthorn-project/One-Core-API-Binaries That adds various NT 6 APIs…

You are right, but blanket statements only need one counter example to be shown to be false. I had looked into cancer data because I read some remarks made about cancer between the…

Are the outcomes in the US worse? Not that long ago (a couple months ago in fact), I looked at public data comparing cancer survival rates, which put the outcomes in the US at leas…

Getting rid of the BIOS sounds awesome. I assume that means that it gets rid of code running the SMM, which can prevent invisible code from sapping performance from the machine for…

Off the top of my head, here is what that needs: 1. Implementing PR_SET_SYSCALL_USER_DISPATCH 2. Implementing ntsync 3. Implementing OpenGL 4.6 support (currently only OpenGL 4.1 i…

I wonder if paying the boring company to make a tunnel for the cables would be cost effective and avoid complaints. I believe that they can bore tunnels without digging along the p…

If you are willing to give up incremental compilation, concatenating all C++ files into a single file and compiling that on a single core will often outperform a multi-core compila…

GCC was originally written in GNU C. Around GCC 4.9, its developers decided to switch to a subset of C++ to use certain features, but if you look at the codebase, you will see that…

It depends on the codebase. If the code base deserves to be a case study in how not to do programming, then a rewrite will definitely yield better results. I once encountered this …

I feel like C++ is a bunch of long chains of solutions creating problems that require new solutions, that start from claiming that it can do things better than C. Problem 1: You mi…

That is a misconception. They added VR support to the Xorg server long after people started saying this. New features need to be well written and not break existing things, which i…

Nvidia likely will back port Debian 13 support to their driver if you ask nicely in an email to their Linux bugs email address, although you would probably wait 3 to 6 months for i…
