hi, i'm daniel. i'm a 15-year-old with some programming experience and i do a little bug hunting in my free time. here's the insane story of how I found a single bug that affected over half of all Fortune 500 companies:

say hello to zendesk

If you've spent some time online, you’ve probably come across Zendesk.

Zendesk is a customer service tool used by some of the world’s top companies. It’s easy to set up: you link it to your company’s support email (like [email protected]), and Zendesk starts managing incoming emails and creating tickets. You can handle these tickets yourself or have a support team do it for you. Zendesk is a billion-dollar company, trusted by big names like Cloudflare.

Personally, I’ve always found it surprising that these massive companies, worth billions, rely on third-party tools like Zendesk instead of building their own in-house ticketing systems.

How to record or stream SteamOS 3.X in `gamescope` (Gaming Mode)

Here is another method that uses Flatpak and obs-vkcapture, which don't meet my personal needs but are very likely to be useful for you. In the comments there there is also an obs-gstreamer method.

Here is another method for recording that has its own GUI for Gaming Mode built with Decky Loader.

Force SteamOS to behave very much like Arch Linux

Key phrase: very much like, not identical. Always treat this as more unstable than Manjaro and only expect support with it in my comments section here.

Set a password (if you haven't already) and disable read-only rootfs (yes this means after updating SteamOS [not Steam Client] this will all be deleted and you will have to do all this again if you want

ArchLinux ElGato FaceCam - Chrome V4L2Loopback

IMPORTANT

This is not required any more, you need upgrade your firmware to the version +4.09 using ElGato Cammera Hub

https://help.elgato.com/hc/en-us/articles/4406041241997-Elgato-Facecam-Firmware-Update

Changes in firmware 4.09

Added MJPEG as a fallback video format. MJPEG requires less USB bandwidth and improves compatibility with programs that cannot handle uncompressed video.

Negative Python user experience on Debian/Ubuntu

The user experience of Python on a minimal Debian or Ubuntu installation is bad. Core features like virtual environments, pip bootstrapping, and the ssl module are either missing or do not work like designed and documented. Some Python core developers including me are worried and consider Debian/Ubuntu's packaging harmful for Python's reputation and branding. Users don't get what they expect.

Reproducer

The problems can be easily reproduced with official Debian and Ubuntu containers in Docker or Podman. Debian Stable (Debian 10 Buster) comes with Python 3.7.3. Ubuntu Focal (20.04 LTS) has Python 3.8.5.

How to set up static nspawn IP address networking without a bridge

Note - this article assumes you have reasonable familiarity with systemd, networkd and nspawn/machinectl

What is this guide for

There seem to be a lot of references on the internet for nspawn networking with a bridge - but not on simply using the stock veth networking with static addresses. The default behaviour of nspawn (as of 24/03/20 and systemd:245 on Arch) is to:

Make a virtual ethernet port on the host (defined by /lib/systemd/network/80-container-ve.network)
Make a virtual ethernet port in the container (defined by /lib/systemd/network/80-container-host0.network)
Based on those configurations, serve the host port a random IP from the local network ranges with a 28 bit subnet, and a DHCP server for the host port serves a random IP in the subnet to the container

Backup android app, data included, no root needed, with adb

Note: This gist may be outdated, thanks to all contributors in comments.

adb is the Android CLI tool with which you can interact with your android device, from your PC

You must enable developer mode (tap 7 times on the build version in parameters) and install adb on your PC.

Don't hesitate to read comments, there is useful tips, thanks guys for this !
