In 1965, Mary Allen Wilkes was writing software in her parents’ Baltimore home for a computer that weighed about 250 pounds and sat in the living room like a piece of laboratory equipment that had wandered into the wrong century. The machine was the LINC, short for Laboratory Instrument Computer. It had a small display, a keyboard, magnetic tape drives, toggle switches, and enough memory to make a modern smartwatch look like a supercomputer. Wilkes was finishing LAP6, the interactive operating system that made the LINC usable by scientists who were not computer specialists. She was also doing something that…

There’s a version of physician productivity advice that sounds like this: wake up earlier, batch your tasks, use the Pomodoro technique. And there’s nothing wrong with any of it. But it’s all still you doing the work. The more useful question is: which of these tasks didn’t need you in the first place? For most physicians building income outside of medicine, the answer is more than they realize. And the most cost-effective way to address that gap is also one of the least utilized: a virtual assistant. Not a full-time hire. Not a complex system. A part-time VA, starting with…

International graduate enrollment at U.S. colleges fell again this year, and the financial damage is showing up fast in layoffs, budget deficits, and shuttered degree programs. For years, foreign graduate students were a quiet engine of university finances: paying full tuition, staffing research labs, and filling master’s programs that schools built out to grow revenue. Now that engine is stalling. Tighter visa policies, thousands of revoked visas, and growing uncertainty about studying in the U.S. have cut into the pipeline, and the institutions that bet most heavily on international enrollment are the ones now scrambling to close the gap. Would you…

Sixty-two members of Congress are demanding the Department of Education act before millions more borrowers fall into default and they want answers by June 22.A June 7 letter (PDF File) led by Senators Elizabeth Warren (D-Mass.) and Jeff Merkley (D-Ore.), along with Representatives Ayanna Pressley (D-Mass.) and André Carson (D-Ind.), warns Education Secretary Linda McMahon that the U.S. is facing “the largest student loan default and delinquency crisis on record.” This comes as the entire student loan system is changing on July 1 – from new repayment plans, loan caps, and borrowers in the SAVE plan being forced to leave forbearance. …

The original Macintosh keyboard was not missing arrow keys by accident. When Apple put the Macintosh on sale on January 24, 1984, the machine arrived with a compact beige keyboard that had no cursor arrows, no function-key row, and no built-in numeric keypad. For a computer that was supposed to sell the public on a graphical interface and a mouse, that absence was part of the point. Steve Jobs wanted the Macintosh to feel like a clean break from the command-heavy machines around it. In a 1985 Playboy interview about the Macintosh and the mouse, he argued that pointing was…

Investors are cheering the idea that Intel could serve as a backup chip manufacturer for Nvidia and Google.

Joe Sutter’s Boeing team began shaping the 747 around a future they thought would pass it by: a supersonic age in which the huge, slower jumbo would eventually make its real living as a freighter. That assumption is why the cockpit sits on a hump. By lifting the flight deck above the main deck, Boeing left room for a nose that could swing upward on freighter versions of the airplane, letting cargo loaders feed pallets and outsized freight straight into the long tube of the fuselage. Every passenger lounge, every Pan Am poster, every 747-8F still hauling cargo at night…

For Elon Musk’s ambitious Terafab project in Texas to be successful, Musk is going to need lots of ASML’s industry-leading lithography machines.

On the morning of July 27, 1866, the SS Great Eastern dropped anchor in Heart’s Content, Newfoundland, with 1,686 nautical miles of insulated copper cable trailing behind her across the floor of the North Atlantic. The cable’s other end sat in Valentia, Ireland. Within hours, an operator was tapping out test signals that crossed to London in minutes. The same news, sent by the fastest mail steamer of the era, would have taken roughly ten days. The ship was a leviathan. Designed by Isambard Kingdom Brunel, she displaced more than 32,000 tons and was the only vessel afloat large enough…

When you were a kid, did you ever dream of growing up to be someone’s exit liquidity? Probably not. But every time you buy shares in a company IPO, that’s exactly what you become. Whether being an early investor’s exit liquidity is good or bad is hard to say in the short run. In the long run, you will certainly find out. The main reason I’ve been investing a greater percentage of my capital in private companies over the past 20 years is because private companies are staying private for longer. More of the gains are accruing to private investors…
