This is the least you need to know to get to use a Python virtual environment. What is a Virtual Environment At its core, the main purpose of Python virtual environments is to create an isolated environment for Python projects. This means that each project can have its own dependencies, regardless of what ...
This article is about erasing disc drives securely. Specially for SSD drives, writing zeros or random data to discs is not good enough and counterproductive. One way to do secure erase (for disposal) is to begin with an encrypted disc. However, after the fact the following options are possible: ATA Secure Erase ...
I am running void-linux at home with musl as the standard C library. While most things work well, there is a number of programs that do not and must be using glibc counterparts. To enable this I followed this guide here: Live switching Void Linux from glibc to musl. To set-up: ...

The other day I needed to copy a bunch of files between to servers in my home network. Because of the volume I wanted to copy the files without having to go through ssh's encryption overhead. So I figured I could use netcat for the data transport. To do that I wrote these short scripts. Remote scripts ...
I am currently using libvirt for managing my VMs. For virtual discs I am using LVM2 volumes. On a regular basis I need to resize these virtual discs, but not that often that I can do this from memory. This is a short procedure to do this: ls -l /dev/vgX/lvX # note down the major/minor numbers for later lvextend -L +50G /dev/vgX/lvX # adding 50GB to this volume ...
I couldn't find any to the point documentation on how to do this, so I am writing this. The way I understand Z-Wave associations work is that once devices are in the same Z-Wave network, a device can directly send a command to another device without intervention of the Hub or controller. ...
The point of this recipe is to create a encrypted file sytem so that when the disc is disposed, it does not need to be securely erased. This is particularly important for SSD devices since because of block remapping (for wear levelling) data can't be overwritten consistently. The idea is that the boot/root filesystem containing the encryption ...
I made the switch to void linux. Except for compatibility issues around glibc, it works quite well. Most compatibility I have worked around with a combination of Flatpaks, chroots and namespaces. The highlights of void linux: ...

Over the years, We've seen many people use this pattern (filter-map): $ [data is generated] | grep something | awk '{print $2}' but it can be shortened to: $ [data is generated] | awk '/something/ {print $2}' You (probably) don't need grep Following this logic, you can replace a simple grep with: ...
