An anonymous reader writes "The Advanced Concepts Team of the European Space Agency is celebrating World Space Week (4-10 October 2010) with the release of 'The Space Game,' an online game for interplanetary trajectory design. The Space Game is an online crowdsourcing experiment where you are given the role of a mission designer to seek the best path to travel through space. The interactive game, coded in HTML5, challenges the players to devise fuel-efficient trajectories to various bodies of the Solar System via a user-friendly interface. The aim of the experiment is get people from all ages and backgrounds to come up with better strategies that can help improve the effectiveness of the current computer algorithms. As part of the events organized worldwide for Space Week, the first problem of the game is to reach Jupiter with the lowest amount of propellant. The best scores by 10 October will be displayed on the Advanced Concepts Team website and the three best designs will also receive some ESA prizes."

Norwegian radio journalist Pia Beathe Pedersen quit on the air complaining that her bosses were making her read news on a day when "nothing important has happened." Pedersen claimed that broadcaster NRK put too much pressure on the staff and that she "wanted to be able to eat properly again and be able to breathe," during her nearly two-minute on-air resignation.

Whether they annoy you or fulfill your nerdy collection habit, achievements have spread across the gaming landscape and are here to stay. The Xbox Engineering blog recently posted a glimpse into the creation of the Xbox 360 achievement system, discussing how achievements work at a software level, and even showing a brief snippet of code. They also mention some of the decisions they struggled with while creating them: "We are proud of the consistency you find across all games. You have one friends list, every game supports voice chat, etc. But we also like to give game designers room to come up with new and interesting ways to entertain. That trade-off was at the heart of the original decision we made to not give any indication that a new achievement had been awarded. Some people argued that gamers wouldn't want toast popping up in the heat of battle and that game designers would want to use their own visual style to present achievements. Others argued for consistency and for reducing the work required of game developers. In the end we added the notification popup and its happy beep, which turned out to be the right decision, but for a long time it was anything but obvious."

An anonymous reader writes "Wondering where all that bloat comes from, causing even the classic 'Hello world' to weigh in at 11 KB? An MIT programmer decided to make a Linux C program so simple, she could explain every byte of the assembly. She found that gcc was including libc even when you don't ask for it. The blog shows how to compile a much simpler 'Hello world,' using no libraries at all. This takes me back to the days of programming bare-metal on DOS!"

Here is the start of the thread on the xkcd forums; and here is the post revealing the final message (a latitude and longitude plus a date and time)."
