Installing microk8s in an LXC container

I wanted to run Microk8s on a Proxmox 6 host inside of an LXC container. These are my notes from the journey.

Create a privileged LXC container through the Proxmox web interface

Enable nesting and FUSE
- In Proxmox UI, select container, then Options > Features > Check nesting and FUSE boxes

SSH into the Proxmox host and edit the container's config in /etc/pve/lxc/.conf
- Add the following lines

lxc.apparmor.profile: unconfined

PST Archive to RFC822

This script extracts all emails from an Outlook PST archive and saves them into some output folder as individual RFC822 compliant *.eml files.

Installing the external dependency pypff may not be straight forward (it wasn't for me). I forked the original repository to make it work in Python 3. If you get errors, check their wiki pages for help or try my fork. Below are the steps that worked for me:

Clone https://github.com/libyal/libpff/tree/master/pypff

sudo sed -i -re 's/([a-z]{2}\.)?archive.ubuntu.com|security.ubuntu.com/old-releases.ubuntu.com/g' /etc/apt/sources.list
sudo apt-get update && sudo apt-get dist-upgrade

mkdir wily && cd wily
wget http://old-releases.ubuntu.com/ubuntu/dists/wily-updates/main/dist-upgrader-all/current/wily.tar.gz
tar -xzf wily.tar.gz

sed -i -re 's/([a-z]{2}\.)?archive.ubuntu.com|security.ubuntu.com/old-releases.ubuntu.com/g' Ubuntu.info
sed -i -re 's/([a-z]{2}\.)?archive.ubuntu.com|security.ubuntu.com/old-releases.ubuntu.com/g' Ubuntu.mirrors

How to make a Release Android App debuggable

Let's say you want to access the application shared preferences in /data/data/com.mypackage.
You could try to run adb shell and then run-as com.mypackage ( or adb shell run-as com.mypackge ls /data/data/com.mypackage/shared_prefs), but on a production release app downloaded from an app store you're most likely to see:

run-as: Package 'com.mypackage' is not debuggable

Stevey's Google Platforms Rant

I was at Amazon for about six and a half years, and now I've been at Google for that long. One thing that struck me immediately about the two companies -- an impression that has been reinforced almost daily -- is that Amazon does everything wrong, and Google does everything right. Sure, it's a sweeping generalization, but a surprisingly accurate one. It's pretty crazy. There are probably a hundred or even two hundred different ways you can compare the two companies, and Google is superior in all but three of them, if I recall correctly. I actually did a spreadsheet at one point but Legal wouldn't let me show it to anyone, even though recruiting loved it.

I mean, just to give you a very brief taste: Amazon's recruiting process is fundamentally flawed by having teams hire for themselves, so their hiring bar is incredibly inconsistent across teams, despite various efforts they've made to level it out. And their operations are a mess; they don't real
