kandi X-RAY | nix Summary
The NIX project started as an initiative within the Electrophysiology Task Force a part of the INCF Data sharing Program. The NIX data model allows to store fully annotated scientific dataset, i.e. the data together with its metadata within the same container. Our aim is to achieve standardization by providing a common/generic data structure for a multitude of data types. See the wiki for more information. The current implementations store the actual data using the HDF5 file format as a storage backend.

There you can see that the macro ::bitflags::bitflags! is called and that libc_bitflags almost redirects the full input to bitflags. You can read more about that crate here.

Using the os/exec package, I want to run an external command on a *nix OS with another user instead of root. (The main process runs under root user).

QUESTION
How can I resolve this sysmalloc assertion:
main: malloc.c:2542: sysmalloc: Assertion `(old_top == initial_top (av) && old_size == 0) || ((unsigned long) (old_size) >= MINSIZE && prev_inuse (old_top) && ((unsigned long) old_end & (pagesize - 1)) == 0)' failed.
Am I making some obvious memory related errors in the 2 functions Valgrind refers to (i.e. set_slice_array() and print_int())?
After doing some research, it seems that the error I'm seeing potentially could be caused by me overwriting some record (that malloc needs) on the heap of its past allocations. But I'm still learning the ropes of dynamic memory allocation in C, so I'm not sure how to resolve the issue(s).
Running my program through Valgrind, gives me the following info (and two hints about an "Invalid write" and an "Invalid read"):

I want to create a Cabal project with the possibility to include multiple packages in the same project. When I read Cabal documentation, it says that one has to create a "cabal.project" file. Is this file created manually into the project root or is there a command to create it? The documentation says that all modifications shall be made in the "cabal.project.local" file. How this file is created? Does this mean that to create a cabal project with multiples packages one has to have a "cabal.project" file and a "cabal.project.local" file in the same project root? Thanks.
...ANSWER
Answered 2022-Feb-16 at 13:17Don't overthink this. A cabal.project file is mostly just listing some packages that you want to build together as a unit, instead of pulling them from Hackage. So yeah, simply create it manually.
What the docs mean by ‘all modifications shall be made in the "cabal.project.local" file’ is that the cabal.project should specify what is always needed to build the project (e.g. packages that simply aren't on Hackage at all, but are included in your repo either directly or as Git submodules), whereas if you just make some tweaks (e.g. experimentally testing out what needs to be changed so your package will compile with a new version of some 3rd-party dependency, which you've checked out locally before considering to file a pull request or to fork it into your own repo) then this should go in the cabal.project.local file. But honestly, you could as well make the changes in cabal.project and then simply not git add them†.
IMO all actually important information to make the package future-proof should reside in the packagename.cabal file and/or a stack.yaml file, not in cabal.project.
†The danger here is that it's easy to accidentally commit changes that were only meant to be local to already-VCS'd files. I always use git add -p so that I review any changes I'm adding, before committing.
QUESTION
for a university project I am testing the log4j vulnerability. To do this, I use a python server that connects to the java client by creating a reverse shell. Everything works except the output to server which is not displayed correctly. Specifically, the server shows the output of two previous inputs and I'm not understanding why. I'm new to python and java programming so I'm a little confused.
Initial project: https://github.com/KleekEthicalHacking/log4j-exploit I made some changes and added a python socket to handle the reverse shell.
PS: with netcat it seems to work fine but command with some space non work (ex: cd .. not work)
For run this project i use kali linux (python server) and ubuntu (java webapp). This code does not yet manage clients with windows os

I have two Nix Flakes: One contains an application, and the other contains a plugin for that application. When I build the application with the plugin, I get the error
...ANSWER
Answered 2022-Jan-04 at 20:29The reason is that the file modules.txt generated as part of vendoring will contain the nix store path in the replace directive in this scenario. The vendor directory is a fixed output derivation and thus must not depend on any other derivations. This is violated by the reference in modules.txt.
This can only be fixed by copying the plugin's sources into the sources derivation – that way, the replace path can be relative and thus references no other nix store path.
