I’ve previously presented a manual process for doing this, but lately I’ve had to do it more often, and I figured it was about time for automation. This script will: Run e2fsck on the root file system Erase logfiles, such as bash_history and stuff in /var/log Erase the test.h264 video file Wipe resolv.conf Defragment the […]
Mostly notes to myself, but hey, maybe it helps you too! Get Kali for the GPD Pocket I installed using re4son’s modified image from here. Removing the GRUB splash screen (it’s sideways anyway, which looks horrible, and I’m not multibooting) /etc/default/grub GRUB_TIMEOUT=0 GRUB_BACKGROUND=”” Speeding up WiFi so it doesn’t lag if you SSH into the […]
“We removed extra line breaks from this message.” Well, how helpful of you. Now the email from my crontab script is all in one line. You can disable this “helpful functionality” permanently in Outlook by doing this: Open Outlook On the File tab, select Options In the Options window, select Mail In the Message format […]
So, the machine auto-activates Windows 10 Home Edition at install time. No prompts, no nothing. You insert the generic upgrade key, and it throws an unhelpful error message back at you: Error code 0x83FA067 means exactly the same thing, as does 0xC004F069. This probably surprises nobody, but trying again, as the above message suggests, will […]
Cheap Windows 10 capable devices often come with very limited internal storage space. To make use of this, it is of course crucial that Windows itself takes up as little space as possible. To combat the bloat, there’s a little known feature in compact.exe, the built-in disk compression tool, that compresses the operating system itself, […]
I recently reinstalled one of these cheap-ass, but surprisingly well built for the price, “ultraportable” laptops. Here’s the WiFi driver to get you started, and the remaining drivers that were not available from Windows Update. Enjoy.
Tasked with cleaning up an installation script, I noticed it was calling dpkg dozens of times to verify that the required packages were in place. On a Raspberry Pi, or similar low powered device, this takes ages. I replaced it with the following: c=0 while read -r pkg; do printf ‘Missing package: %s\n’ “$pkg” >&2 […]
Working with multiple screens, I often use several windows in Visual Studio. For a while now, I’ve been annoyed by all the miscellaneous windows forcing themselves on top so I couldn’t open a browser on one screen and switch to the code on another screen without the window on the browser’s screen popping up to […]
No subprocess, no sleep command, no coproc, no nothing? Yes. Sleeping in bash script is traditionally done with the sleep (1) command, which is external to bash, the command /bin/sleep. However, if you have a bunch of scripts running that all sleep this way, the output of ps looks like a mess, pstree looks like […]
Some hypervisors for virtual machines do not properly support sending a fake system time to the guest operating system, thus making Windows guests display the wrong time if their timezone is set to anything except UTC. This happens because Windows, by default, keeps the system clock set to the local time. This is stupid. The […]
