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 about it until it breaks. Learning that there are better o

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. The window units are cheap, but inefficient. The central units

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. Theoretically, if the leak occurs under warranty, it should

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 OpenSolaris.

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 range.

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 microcontroller: https://magazine.raspberrypi.com

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 Ethernet device that the Nintendo Switch / Nintendo Switch

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 gigabyte of space was a fantasy to most people. Now, I wonder when

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 that were stripped out of this version

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 and even compatibility modes for vari

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 US and Europe and I was curious if they were true. For what

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 least 10% better than those in the UK. That was additive, such t

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 no apparent reason. For example, on recent AMD machines, su

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 is supported) 4. Implementing Vulkan 1.4 with vario

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 path on the surface.

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 compilation. The reason is that the compiler spends most of its tim

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 much of it is still GNU C, compiled as GNU C++. There is no

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 situation with C# code written by an undergraduate, rewrote

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 might fail to initialize an object in memory correctly. Soluti

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 is hard to do. The entire premise of Wayland was to make a cl

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 it. They periodically back port support for newer systems to

I have had minimal problems with KDE 6 and Wayland, but I dislike the idea that both cannot co-exist. There is no reason to force people to Wayland. There are applications that benefit from Wayland’s tighter security model while there are a
