To power AI, startup creates a giant computer chip

SAN FRANCISCO: The largest computer chips would usually fit in the palm of your hand. Some could rest on the tip of your finger. Conventional wisdom says anything bigger would be a problem. Now a Silicon Valley startup, Cerebras, is challenging that notion. On Monday, the company unveiled what it claims is the largest computer chip ever built. As big as a ... Read More »

The Story of the Apollo Guidance Computer, Part 3

During the development of the Apollo Guidance Computer (AGC) by the MIT Instrumentation Laboratory (see Part 1 and Part 2 for the complete backstory), an inauspicious event occurred sometime during 1965-1966, while the Gemini missions were going on. The Gemini program helped NASA get ready for the Apollo Moon landings missions by testing out rendezvous and other critical techniques and technologies. Ten crews flew ... Read More »

Why Computer Science Needs The Humanities

The humanities are under assault. University administrators eye falling enrollment and the lucrative funding streams of their engineering campuses, while parents shepherd their children towards high-paying technology jobs the press touts as today’s ticket to a stable career. Across nearly every humanities major, enrollment has been falling precipitously. Yet as students flock to STEM careers like computer science, they are losing the ... Read More »

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. QUANTA MAGAZINE ABOUT Original story reprinted with permission from Quanta ... Read More »

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 »
