If you are talking about provisioning dot files and command line applications you want to have available on all you machines then take a look at home-manager. https://github.com/nix-community/home-manager I use it on N

I guess you cannot install Nix on that Mac because you are not admin? In general you can install the Nix Package Manager and home-manager an macOS. There were some rough edges when macOS Catalina came out, but that should be resolved now. T

Big disclaimer: I have only used home-manager on NixOS. The main development target for the project seems to be NixOS, but you can install it on other Linux distribution or macOS as well. It just depends on the Nix Package Manager, which yo

For using Python packages that are avialable via pip I have been quite happy with [mach-nix]( https://github.com/DavHau/mach-nix ), which can pull prebuilt python wheels(?) from pip directly. You can also configure it to

I can imagine sitting down and migrating a lot of complex packages to Nix is probably quite a tall order right now. Partially because I think a switch like that is always painful, but also because of the open issues, bugs, yet unanswered qu

Were you trying to use Nix for running your graphical terminal on a non-NixOS system? I have personally worked with Nix on a Fedora system, but only for things that run inside the terminal. EDIT: I removed some content here because it didn&

This is about right but let me clarify a bit. The configuration.nix system configuration can be moved between systems, but imports a generated hardware-configuration.nix that really should not be moved between systems. If you don't wan

That's an accurate description. I just want to add some info how the install process ifself works so people get a better picture of it. For the initial installation you actually have to set up the partitions and mounts inside the root

If you are interested in Nix but don't know too much about it, let me tell you one thing: You can use the package manager to package, build and install software and to take advantage of their large package repo and features like nix-sh

I did read the article. I am interested in how forensic evicende like that is gathered in general and how reliable it is in general. It's debatable what role that fingerprint played in that investigation, but I did not want to call int

'So we have these fingerprints, and we think they belong to this guy we already have prints on file for. Can you give us a yes/no answer if they match up?' seems like a pretty low bar for evidence. Seems like the kind of thin

I think an organization should be able to deliver on what it promises when hiring someone even to an intern and both parties expectations should be expressed in good faith as clearly as possible. Frankly if someone told me they were cleanin

Are there implementations that actually do this? I would think the page level granularity of virtual memory makes it not that useful for this purpose, since the used and unused parts of the two pages would have to line up nicely and larger

If I remember correctly you couldn't do this by just re-linking with another manual memory manager though because the application could hold pointers to things in ways you don't understand and then you can't move them, so the

by mschwaig 7y ago
I fully agree that moving is key. Just to further clarify the terms if someone is looking for more info on this: In the context of system memory people mostly refer to this as compaction and not defragmentation.

In their phylosophy C and zig both aim to do very little behind the scenes beyond what you explicitly express in your code. On a technical level Zig re-uses fancy C compiler infrastructure in the form of LLVM. So that gets them pretty clo

I am amazed how much money and effort goes into building software on top of the ancient wasp nest that is C. People boldly taking on that issue deserve our support.

Yes for most userland applications removing hidden allocations is not a concern, which is why for most general purpose programming languages this is way down the priority list. Most languages make allocations behind your back so that your c
