A DECADES-OLD COMPUTER SCIENCE PUZZLE WAS SOLVED IN TWO PAGES

A paper posted online this month has settled a nearly 30-year-old conjecture about the structure of the fundamental building blocks of computer circuits. This “sensitivity” conjecture has stumped many of the most prominent computer scientists over the years, yet the new proof is so simple that one researcher summed it up in a single tweet.

How to check which version of Windows your computer is running

Do you know which version of Windows you’re running? Most of the time, there’s little reason to care. But sometimes you need to know. Some programs and computer hardware will only work with a specific version of Windows, for example. You might also need to know if it’s time to upgrade. Microsoft generally supports each version of its operating system for about ten years, ... Read More »

A computer system that knows how you feel

Researchers use fMRI brain imaging technology at CU Boulder. Credit: Glenn Asakawa/CU Boulder Could a computer, at a glance, tell the difference between a joyful image and a depressing one? Could it distinguish, in a few milliseconds, a romantic comedy from a horror film? Yes, and so can your brain, according to research published this week by CU Boulder neuroscientists. ...

How to change your Twitter username on a computer or mobile device

Facebook only allows you to change your username once every few months, and the name you choose must be at least a reflection of your real legal name, though common sobriquets are acceptable. Twitter, on the other hand, has no such limitations in place when it comes to usernames. You can change your Twitter username daily if you so choose, and it can ... Read More »

How to activate and access iCloud Drive on a Mac computer

While iPads and iPhones are obviously great devices, the Mac is still one of the best bits of consumer technology in the modern era. Apple’s iCloud is a great way to share data and projects across devices, and with the Mac’s enhanced ability to execute projects (from Photoshop to video editing to writing, Mac still rules supreme), you should know how to access iCloud from your Mac computer. There are several ways to quickly and easily ... Read More »

Your Smart Toaster Can’t Hold a Candle to the Apollo Computer

Without the computers on board the Apollo spacecraft, there would have been no moon landing, no triumphant first step, no high-water mark for human space travel. A pilot could never have navigated the way to the moon, as if a spaceship were simply a more powerful airplane. The calculations required to make in-flight adjustments and the complexity of the thrust ... Read More »

Britain Honors Computer Scientist Alan Turing as The Face of Their New Bank Note

Alan Turing, a founding father of computer science and artificial intelligence, was revealed Monday as the face of Britain’s new 50-pound bank note. Turing was also famed as a World War II codebreaker whose work was widely credited with hastening the end of the war and saving thousands of lives. But at the time, his achievements were overshadowed following his ... Read More »

Page through computer history with this complete scan of NeXT’s Fall 1989 catalog

An amateur computer historian has unearthed a cool piece of technology paraphernalia: NeXT’s Fall 1989 catalog. Kevin Savetz recently scanned the entire 138-page book, and posted the files to Archive.org. NeXT was the company that Steve Jobs founded in 1985 after he was fired by Apple. The company designed computer workstations and lasted through 1997, when Jobs was rehired at Apple. ... Read More »

Computer password inventor Fernando Corbato dies at 93

Computer security just lost one of its founders. Fernando “Corby” Corbato, credited with inventing the computer password, has died at the age of 93. The MIT researcher devised the concept of password-protected user accounts when establishing his Compatible Time-Sharing System, which let multiple people use a computer at the same time. It was just a matter of establishing “compartmentalization” and ... Read More »

New form of computer memory is 1,000 times faster

A new type of computer memory could speed up certain kinds of data operation by 1,000 times while also being easier to code for than traditional memory. The amount of data generated each year is on an exponential incline. The developers of the new form of memory, Blueshift Memory, believe their new technology will better cope with the increasing demands. ... Read More »
