I am trying to get Radare2 installed on my Windows machine. I do have Windows Subsystem for Linux up and running if that changes things. I have tried the git technique from their website:
git clone https://github.com/radare/radare2
cd radare2
sys/install.sh
This did strange things depending on what I did. There are some comments headed with the # symbol that explain what's going on.
#-----Here I clone the repo.

At this point, I decided to try and use the Windows binary instead. I went to the download page and downloaded the windows binary, then unpacked it into my AppData programs folder. I then opened that folder and double-clicked on radare2.exe. This made a quick blip on the taskbar like a window was trying to open, which also immediately closed.
At this point, I suspect errors in the source code for Radare2 are causing it to crash almost immediately. Is this the case? Or do I need to do something different to get this running?
-----Solved-----
I went and experimented a little, including installing to a Linux VM using the git clone method. I have found that the windows binary is the way to go for this. to use it, unpack the downloaded binary, then open CMD/PowerShell in the radare2 directory, then run bin/radare2.exe or bin/r2.bat. You will need to manually add these to the path, though.

I have installed and used screen many times on several different operating systems. Recently I installed it on a NetBSD-8.0 virtual machine.

This problem persists even when I first remove, then reinstall the screen package. Any suggestions as to what's wrong?
My guess is that the system used to build binary packages for 8.0 (as of the 8.0_2020Q1 pkgsrc release) is no longer quite compatible with the NetBSD-8.0 release. It is likely running on a newer release, inside a chroot(8) sandbox.
I would recommend using NetBSD-9.0 instead, as that is the latest NetBSD release, or NetBSD-8.2, as that is the latest release in the netbsd-8 branch. Using the latest NetBSD and pkgsrc releases provides better coverage against unpatched vulnerabilities.
However, if you want to keep using NetBSD-8.0, you can get a working screen(1) from the 8.0_2019Q4 pkgsrc release. To have pkgin(1) pull from that release, edit the /usr/pkg/etc/pkgin/repositories.conf file to use this repository URL:
http://ftp.NetBSD.org/pub/pkgsrc/packages/NetBSD/amd64/8.0_2019Q4/All
There is currently likely just one line in the file that is not commented out, and it points to a URL with just 8.0 in it (which on the server is a symbolic link to the latest pkgsrc release). Just replace that line, or comment it out and add the above line.
Then remove and re-install screen:
sudo pkgin remove screen && sudo pkgin install screen

My HDD is formatted as exFat which doen'nt seem to support the readlink operation.
I am trying to set up a gatsby page via the gatsby CLI. The 'gatsby new' wokrs and set's up everything nicely, as far as I can tell. When it comes to starting the develop server I get the Error like in the title: "Error: EISDIR: illegal operation on a directory, readlink './path/on/my/hdd/.cache'
I learned, that "EISDIR means that the target of the operation is a directory in reality but that the expected filetype of the target is something other than a directory." (Using Node.js I get, "Error: EISDIR, read").
What drives me mad is, that a file called .cache wouldn't make much sense, so somewhere deep down in this gatsby jungle has to be something, that gets messed up.
I've tryed node Versions 10.16.0 and 12.2.0 managed via nvm on windows 10. I've tryed different Folders and Harddrives, I've force cleared my node cache, I've tryed different starter packages, I've tryed npm update on the node_modules installed via gatsby.

When I run xampp on fedora this error is showing up on application log
Starting Apache Web Server...
Exit code: 8
Stdout:

can anyone tell me how can I solve this?
it seems you're missing libnsl. install it through this command:
sudo dnf install libnsl
In case this doesn't work you can then download it manually:
Visit https://pkgs.org/
In the search box (pkgs.org of course) type libnsl.so.1 and choose the appropriate OS. The version shown might be higher e.g libnsl-2.28-9.fc29.x86_64.rpm, but it doesn't matter, the file needed is also included in this very package.
In the terminal, navigate to the directory where the .rpm was downloaded.
Type the following command to install it:
sudo rpm libnsl-2.XX-X.fc29.x86_64.rpm
Upon completion everything should be working fine.
A quick Google search returns this: https://www.reddit.com/r/Fedora/comments/8hlhlv/xampp_with_fedora_28/
The suggested fix is installing libnsl from this source:

I have 2 machines -
dccten1a with no internet access where I need to install Tensorflow with GPU support
dccten1b with internet access so that I can download packages and transfer to dccten1a
In the final step of installing Tensorflow, when running the bazel build command to produce a whl file, I get an error which says that it can't find a file in a folder it is looking in, and also cannot download, obviously, as 1a doesn't have internet access.
bazel build --config=opt --config=cuda /home/tensorflow/Documents/tf_dependencies/tensorflow-master/tensorflow/tools/pip_package:build_pip_package --cxxopt="-D_GLIBCXX_USE_CXX11_ABI=0"

I checked in the system, and there is no such directory as shown in the error message (i.e., /home/xyzuser/.cache/bazel/_bazel_xyzuser/cb1e63cb5e61cab49a9fd2f5ba92d003/external/io_bazel_rules_closure/). So, I created it, searched and found the requisite (?) file online, downloaded the file in the machine with internet, transferred it to the target machine, moved the file to the just created directory, and tried running the command again:
(tensorflow#dccten1a):
mkdir -p /home/tensorflow/.cache/bazel/_bazel_tensorflow/cb1e63cb5e61cab49a9fd2f5ba92d003/external/io_bazel_rules_closure

Then I run the bazel build command again, but the same error persists.
Use --experimental_repository_cache to download the dependencies on the machine with internet access, transfer the cache to the machine without internet access, and use --experimental_repository_cache to refer to the same cache.
e.g.
1) On the machine with internet access, run
tensorflow#dccten1b $ bazel build --experimental_repository_cache=/path/to/some/folder --config=opt --config=cuda /home/tensorflow/Documents/tf_dependencies/tensorflow-master/tensorflow/tools/pip_package:build_pip_package --cxxopt="-D_GLIBCXX_USE_CXX11_ABI=0""
2) Copy the cache at /path/to/some/folder to the machine without internet access using a SD card or flash drive.
3) On the machine without internet access, run the same command again and setting the flag to the cache's location.
tensorflow#dccten1a $ bazel build --experimental_repository_cache=/path/to/some/folder --config=opt --config=cuda /home/tensorflow/Documents/tf_dependencies/tensorflow-master/tensorflow/tools/pip_package:build_pip_package --cxxopt="-D_GLIBCXX_USE_CXX11_ABI=0""
My hand-made debian package wont install if i build it on Squeeze (well, a squeezechroot)?
If i built it on a wheezy box though it builds installable packages.
Note that it builds fine in either case. Im generating the debian packages using CMake/CPack.
The error message i get is:
user#buildbox:/builddir/packagename# dpkg -i packagename_1.0.3.deb
(Reading database ... 35116 files and directories currently installed.)
Unpacking packagename (from packagename_1.0.3.deb) ...

dpkg-deb: subprocess paste killed by signal (Broken pipe)
Errors were encountered while processing:

Might it be that mixer_devices is not contained within the created deb file for some reason?
Just do an ar x packagename_1.0.3.deb and see what the tar file contains.
