If you look in a book on processor design, you’ll find a description of how registers can be created from static memory cells. However, the 386 illustrates that the implementation in a real processor is considerably more complicated. Instead of using one circuit, Intel used six different circuits for the registers in the 386.

In 2007, on my first trip to New York City, I grabbed a brand-new DSLR camera and photographed all the fonts I was supposed to love. I admired American Typewriter in all of the I <3 NYC logos, watched Akzidenz Grotesk and Helvetica fighting over the subway signs, and even caught an occasional appearance of the flawlessly-named Gotham, still a year before it skyrocketed in popularity via Barack Obama’s first campaign.

But there was one font I didn’t even notice, even though it was everywhere around me. Last year in New York, I walked over 100 miles and took thousands of photos of one and one font only. The font’s name is Gorton.

Most of the time, Chile’s Atacama Desert is gritty, cracked, and red. The desert gets less than 0.6 inch (1.5 cm) of rain per year, the equivalent of six or so hours of light drizzle. Sometimes it doesn’t get any at all. Generally, the only plants living here have lucked out with real estate, growing near one of the rare streams or groundwater reserves or along the fog-ribboned coast.

Other years, though, are just a little bit damper, juiced by El Niño, a weather pattern that increases rain in the Americas. With a few drops more water, trillions of seeds sleeping just under the sand begin to stir. They send up shoots, which grow leaves and buds. Eventually, whole swaths of the desert let loose, unfolding in yellow, pink, orange, and purple, the colors sweeping across the desert like watercolors, and the petals more numerous than the stars above.

The 386 processor (1985) was Intel’s most complex processor at the time, with 285,000 transistors. Intel had scheduled 50 person-years to design the processor, but it was falling behind schedule. The design team decided to automate chunks of the layout, developing “automatic place and route” software. This was a risky decision since if the software couldn’t create a dense enough layout, the chip couldn’t be manufactured. But in the end, the 386 finished ahead of schedule, an almost unheard-of accomplishment.

In this article, I take a close look at the “standard cells” used in the 386, the logic blocks that were arranged and wired by software. Reverse-engineering these circuits shows how standard cells implement logic gates, latches, and other components with CMOS transistors. Modern integrated circuits still use standard cells, much smaller now, of course, but built from the same principles.

And yet it’s Asimov who apparently owned the only set of postcards of En L’An 2000, a set of 87 (or so) collectible artist cards that first appeared as inserts in cigar boxes in 1899, right in time for the 1900 World Exhibition in Paris. Translated as “France in the 21st Century,” the cards feature Jean-Marc Côté and other illustrators’ interpretations of the way we’d be living... well, 23 years ago.

The German capital is dotted with more than 60 public indoor swimming pools, and many of them are so stunning and tranquil they feel like you’re swimming in an ornate library.

The State Guest Mansions were envisioned as the palatial homes for the upper crust of society. Now, their only residents are hurdles of cattle and the occasional adventure explorers meandering like ghosts around the arched verandas and stone façades of hundreds of abandoned villas. Located around the hills of Shenyang (about 400 miles northeast of Beijing), the development was originally planned by Greenland Group, a Shanghai-based real estate developer, and broke ground in 2010. But as AFP reports, within two years the project had come to grinding halt, leaving the half-formed skeletons of imitative royalty in its wake. Today the crumbling estates are still abandoned, left in an eerie series of rows appearing like an architectural cornfield.

Determining the airspeed and altitude of a fighter plane is harder than you’d expect. At slower speeds, pressure measurements can give the altitude, air speed, and other “air data”. But as planes approach the speed of sound, complicated equations are needed to accurately compute these values. The Bendix Central Air Data Computer (CADC) solved this problem for military planes such as the F-101 and the F-111 fighters, and the B-58 bomber. This electromechanical marvel was crammed full of 1955 technology: gears, cams, synchros, and magnetic amplifiers. In this blog post I look inside the CADC, describe the calculations it performed, and explain how it performed these calculations mechanically.

It’s Art Deco where America seemed to achieve something truly unique.

Still, its implications are wide-ranging. The court is basically saying that whoever presses the camera button owns the copyright, even if the button-pusher doesn’t own the equipment, the camera settings are provided to them, and they get some verbal direction from the camera owner/photo subject about when, where, and how to take the photo. Due to that conclusion, Shah does not own the copyrights to the photos on his phone and he can’t register the copyrights or enforce them.

I was recently shown some frames from a film that I had never heard of: Alejandro Jodorowsky’s 1976 version of “Tron.” The sets were incredible. The actors, unfamiliar to me, looked fantastic in their roles. The costumes and lighting worked together perfectly. The images glowed with an extravagant and psychedelic sensibility that felt distinctly Jodorowskian.

The truth is that these weren’t stills from a long-lost movie. They weren’t photos at all. These evocative, well-composed and tonally immaculate images were generated in seconds with the magic of artificial intelligence.

The “interactive” elements are annoying, but some pretty pictures here.

You might wonder how a charge pump can turn a positive voltage into a negative voltage. The trick is a “flying” capacitor, as shown below. On the left, the capacitor is charged to 5 volts. Now, disconnect the capacitor and connect the positive side to ground. The capacitor still has its 5-volt charge, so now the low side must be at -5 volts. By rapidly switching the capacitor between the two states, the charge pump produces a negative voltage.

As you approach Nithurst Farm, architect Adam Richards’ new house, the sheep look up suspiciously from their grazing. You feel like an intruder. Sitting in the middle of the undulating Sussex countryside, the house looks more like a piece of railway viaduct or a bit of agricultural or industrial infrastructure left over from some obscure purpose than a conventional dwelling. It might even be a ruin, the stray remains of a Roman villa.

The revolutionary Intel 8086 microprocessor was introduced 42 years ago this month so I’ve been studying its die. I came across two 8086 dies with different sizes, which reveal details of how a die shrink works. The concept of a die shrink is that as technology improved, a manufacturer could shrink the silicon die, reducing costs and improving performance. But there’s more to it than simply scaling down the whole die. Although the internal circuitry can be directly scaled down, external-facing features can’t shrink as easily. For instance, the bonding pads need a minimum size so wires can be attached, and the power-distribution traces must be large enough for the current. The result is that Intel scaled the interior of the 8086 without change, but the circuitry and pads around the edge of the chip were redesigned.
