@lemmy.dbzer0.comThe entire exeption, and the broader exclusionary rule, is based around the self-evidently incorrect assumption that what happens in court will effect behaviour of investigators.
I generally use 'USican', pronounced yoo-ess-ican. Every seemseto understand me.
Edit: this may be the most controversial thing i've said on lemmy.
Yeah! Its a package manager, with its own repos. It needs its own becauseof all those guarentees above. Its designed to be installed on any linux distro, and also has windows, mac, and docker versions.
If you want it to be all nix all the time, thereis also a distro NixOS thats uses nix from front to back.
And, in a confusing failure of naming, the language you use to configure nix is also called nix, just to be cool.
Ok, heres my run down:
Nix is a package manager with the goal of making it so that when you install a package at a version, you always get the same thing.
But isn't that how all package managers work? Not at all. Most software requires other software to work (dependancies). Those dependencies also have dependencies, and so on. If a version of the dependency changes between installs, your package works differently. So Nix forces the package to specify what version of the dependency to use.
But version numbers are pretty wishy-washy, so nix actually requires git commits. This is good, since it turns out, the compiler and libraries used to build the software are dependencies, too. Building with a different compiler can change the way the package works. So Nix forces the package to specify how to build it also.
So Nix is a package manager where each version of a package is built against a known compiler, and comes bundled with a known set of dependencies.
This allows some cool things, like generations. Change your list of installed packages (or configuratian, it handles that too), nix can save the old config and instantly go back to it. No more bricked linux install (if it can get past the bootloader). Also lets you do os-level per-directory installs. Have two projects that each need a different version of c compiler or postgres? Nix makes that easy. Want to make sure all dev machines in your project have the same python version? Just check in the config.
No bike friendly city, and very few advocates for them, are suggesting to ban motor vehicles entirely. Rather, we can structure infrastrucrue to serve both, instead of just cars.
A 4 lane stroad can be turned into a two lane, limited access road with protected, separated bike lane and a median. This actually improves auto throughput, travel times, and emissions.
A 2 lane residential street can have restricted parking, narrower right of way, and wide rsidewalks. This naturally slows cars, making shared right of way safer for all.
A pedestrian zone can have moveable bollards, so that deliveries and mobility services can still access, whil keeping the street safe for people.
In all these cases, its not about bulldozing buildings, its about changing the way we use existing land.
Thats true. And then America stopped. And then the people who had actual on-the-ground experiance died of old age. Its really another effect of the slow tragedy that is the auto industry
Thats quite true, but also political blockage prevents the projects from starting. With California high speed rail, the project is going. And we have found that, in addition to political stumbling blocks, California simply lacks access to the knowledge to build this, and must build that up. Its not 'instead of politics', its 'in addition to'.
If you look at the context of my comment, you will see I was replying to someone who, it seems, has confused the California high speed rail project with the hyperloop. The first is an actual thing that is being built, the second is a distraction.
As for comparing the situations, of course it can be done. We can look at how the twa countries built rail, see what are fundamental differences and what are things that can be learned.
This is misleadingly reductionist. California high speed rail has made consistant progess in that time. That progress has been slower than ourslowest expectations. It demonstrates the void of expertise the US has in rail megaprojects. However, that expertise is being built, slowly and painfully. Its still forward progress for a nation which tore up half its rail overthe last 50 years.
California high speed rail is an actual project which has actually been building actual rail since 2008. It is the only rail megaproject active in the United States. It has many challenges, none of them physics, some of which were mad worse by Musk's bullshit.
Asking for an actual comparison between the circumstances of the Chinese high speed rail network and the circumstances of the California High Speed Rail project is valid.
This response reflects poorly
