The Atari CX40 joystick - first released in 1977, I don't think I need to say too much about it, because it will probably resonate with so many people, by the 1980s, it become so symbolic of video game design of the era and was more iconic than Ataris Fuji logo . .

This IOCCC winner entry (International Obfuscated C Code Contest) made me smile. The code draws the current moon phase to the console.

Chinese scientists have developed the best shortest-path algorithm in 41 years! A team from Tsinghua University has broken Dijkstra’s “sorting barrier” — the first improvement since 1984. The new algorithm runs in O(m \log^{2/3} n) time. Potential applications? Faster shorter

Hackers can create urls that look almost identical to legitimate ones. Can you spot the legitimate url? What type of attack is this.
