PGConf.eu 2023 Speaker Dinner

Traditionally, we (the conference organizers) invite the speakers and volunteers to a dinner the evening before the conference. The venue is downstairs, and the seating splits the larger group up into up to 6 people per table. Ideal conditions to walk around, chat with everyone, talk with old friends and meet new peoole.

My PostgreSQL database is empty!

The one thing I like to do is challenge PostgreSQL - and readers - to the extreme. A while ago I posted about the Beer o'clock. Building Zoé was another interesting example. And at some point I blog about Dancing with the Stars as well. Today it's all about nothing. Empty. Where is all the data gone?

It's beer o'clock for PostgreSQL

A couple days ago Devrim forked PostgreSQL to get a beer. That effort is of course laudable, but a bit extreme. PostgreSQL is very extensible, and allows to implement a beer now clock with just a few easy steps.

GSoC 2021 completed

Wow! The PostgreSQL Project got all 7 proposals accepted into Google Summer of Code 2021!

Advent of Code 2020: "Seating System" - Day 11

Your career as a hacker brings you more and more unreasonable tasks. Today you arrive at the ferry station, head to your next gate (no one mentioned if you even got an ice cream), and figure out where to seat. Even though you are the first person in the waiting area that does not stop you from knowing the seating habits for all other passengers, and calculate their seating patterns.


Advent of Code 2020: "Adapter Array" - Day 10

After you finished hacking the plane, your laptop dies: you forgot to charge it! Rookie mistake, or the calculations do consume a lot of power. The plane has a power outlet, but somehow it’s a non-standard one, you need an adapter. But first a cocktail! Then you empty your backback on the seat next to you and find out that you have dozens of different adapters, which you can stack together. None of them really work, and hopefully you don’t blow another fuse, or set the plane on fire!


Advent of Code 2020: "Encoding Error" - Day 9

Uh oh, either the ice cream at the airport was bad, or the cocktails are not good for you! How else can you explain that you hack the airplane systems with some paperclips and break the XMAS encryption, while the plane is airborne? The plane’s on-board systems emits some cryptic numbers and your task is it to decrypt this. Wait, did I say task? Who gave this task to you? Oh well, please be careful, if you shorten a circuit you might as well crash your own plane.


Advent of Code 2020: "Handheld Halting" - Day 8

You fixed the colours of the bags yesterday) and security allowed you to leave the baggage section and go get your ice cream before you board your next flight. On the flight the kid next to you recognizes you as the great hacker you are, and asks you to fix a problem with the handheld game console. Go and hack the bootloader while no documentation is available because the mobile internet is off. Turns out someone coded an infinite loop into the bootloader, and missed that fact during testing. What testing, do you ask? Well, let’s not jump too deep into details, you have to hack a bootloader and make a kid happy. It’s Christmas soon, after all! And your cocktail is waiting!


Advent of Code 2020: "Handy Haversacks" - Day 7

They really trust you a lot … Now all flights are delayed, that’s quite usual in advent times. Except it’s 2020 and no one is traveling anyway. But they also impose more regulations, and now bags need to have colours, and bags need to go into other bags. And someone has to figure it out. That’s right, it’s you! I hope the stopover is long enough to at least grab some ice cream!
