You must be kidding. The first line on the event homepage says "The GNOME Conference" and the first paragraph after the menu, on the picture of gathered contributors taken at least year's GUADEC, reads: GUADEC is the annual conference of the GNOME community, held in Europe since 2000. GUADEC 2013 will be held in Brno, Czech Republic, a city which has played host to several other successful GNOME-related hackfests in the past. People modded you Informative for that comment. I guess I shouldn't be surprised that the slashdot crowd doesn't bothered checking facts.

+ - Making Metals that Heal Themselves

Submitted by
Hugh Pickens
Hugh Pickens writes "A nuclear reactor is a tough place for metals with all those neutrons bouncing around wreaking havoc with the crystalline structure of steel, tungsten and other metals used in fuel rods and other parts. Over time, the metals can swell and become brittle so designing materials to withstand radiation-induced damage is very important for improving the reliability, safety and longevity of nuclear power stations. Now the NY Times reports that researchers at Los Alamos National Laboratory have shown that by altering the microstructure of metals, they may be able to make reactor parts that are self healing utilizing a previously unknown effect where atoms inside reactor walls became packed together during exposure to radiation, causing damage but then spread out again repairing any defects. When a neutron hits metal, it displaces atoms within the crystal lattice eventually causing the metal to swell, and the vacancies they leave behind can lead to voids that further weaken the material. But it is possible to fabricate metals that have a nonuniform structure, with very small crystal grains, or regions of different phase or orientation so that when atoms are displaced in this nanocrystalline material, rather than traveling to the surface they migrate to the boundaries between the grains. Computer simulations discovered a 'loading-unloading' effect in the interface between single nano-sized particles so that the displaced atoms later become 'unloaded' into the gaps that had been created to repair the material."

Some of the achievements proposed in the comments are actually good references about the slashdot folklore. Keeping a list of them available somewhere could be a good way for newcomers to become familiar with the community they're getting into. P.S.: I wonder if replying to this on the 2nd also gets you the April's fool achievement.
