Perhaps the most dramatic moment of Apollo 11's mission to the moon was when the Eagle began its final descent to the lunar surface and the ship's computer became overloaded. Few were more nervous than the young computer programmer who had written the code for the landing. On the Apollo 11's 50th anniversary, WSJ sat down with programmer Don Eyles.
Computer pioneer Fernando Corbato, who first used passwords to protect user accounts, has died aged 93.
Dr Corbato introduced the basic security measure while developing methods that let more people use a computer at the same time.
He developed a technique, called time-sharing, that divided up the processing power of a computer so it could serve more than one person at once.
Dr Corbato reportedly died as a result of complications caused by diabetes.
The new Raspberry Pi 4 is out, and slowly theyíre working their way from Microcenters and Amazon distribution sites to desktops and workbenches around the world. Before you whip out a fancy new USB C cable and plug those Pis in, itís worthwhile to know what youíre getting into. The newest Raspberry Pi is blazing fast. Not only that, but because of the new System on Chip, itís now a viable platform for a cheap homebrew NAS, a streaming server, or anything else that requires a massive amount of bandwidth. This is the Pi of the future.
The Raspberry Pi 4 features a BCM2711B0 System on Chip, a quad-core Cortex-A72 processor clocked at up to 1.5GHz, with up to 4GB of RAM (with hints about an upcoming 8GB version). The previous incarnation of the Pi, the Model 3 B+, used a BCM2837B0 SoC, a quad-core Cortex-A53 clocked at 1.4GHz.
