Chromium OS ft. Docker

Chromium OS is cool. Chromium OS with crouton is cooler. Chromium OS with Docker is even cooler. This is specifically a guide for the Chromebook Pixel 2 (2015), but I can't think of any reason it wouldn't work with other devices.

Create a build environment
Customize the kernel
Build Chromium OS
Flash Chromium OS to USB
Install Chromium OS

Extracting Emoji From Slack!

Slack doesn't provide an easy way to extract custom emoji from a team. (Especially teams with thousands of custom emoji) This Gist walks you through a relatively simple approach to get your emoji out.

If you're an admin of your own team, you can get the list of emoji directly using this API: https://api.slack.com/methods/emoji.list. Once you have it, skip to Step 3

HOWEVER! This gist is intended for people who don't have admin access, nor access tokens for using that list.

None of these suggestions worked for me, because Android was appending a sequence number to the package name to produce the final APK file name (this may vary with the version of Android OS). The following sequence of commands is what worked for me on a non-rooted device:

Determine the package name of the app, e.g. com.example.someapp. Skip this step if you already know the package name.

adb shell pm list packages

Look through the list of package names and try to find a match between the app in question and the package name. This is usually easy, but note that the package name can be completely unrelated to the app name. If you can't recognize the app from the list of package names, try finding the app in Google Play using a browser. The URL for an app in Google Play contains the package name.

Recovering deleted files in Ubuntu with ext4 filesystem

Recently, I deleted some files by mistake in a Ubuntu machine with an ext4 fs. These notes document the steps I took to get them back.

Important

this procedure assumes that the partition that contained the deleted files is different from the root partition, as that was the scenario with which I had to deal (deleted files were in my home dir). The procedure needs that the partition that contained the files is unmounted, so if the deleted files were in the root partition, the process would be a bit different (e.g. storing the fs journal in a USB stick, using a live CD/USB to boot and issue the commands, etc.)
if something is not clear, you need more information, etc. check the sources below

With that out the way, let's begin.

cd /Library/Preferences
sudo rm com.sophos.sav.plist

cd /Library/Application\ Support/Sophos/cloud/Installer.app/Contents/MacOS/tools/
sudo ./InstallationDeployer —force_remove
