Seth Molson Is Designing The Future, One Show At A Time

October 29, 2018 by Tom Nardi 27 Comments

From the banks of levers and steam gauges of 1927’s Metropolis to the multicolored jewels that the crew would knowingly tap on in the original Star Trek, the entertainment industry has always struggled with producing imagery of advanced technology. Whether constrained by budget or imagination, portrayals usually go in one of two directions: they either rely too heavily on contemporary technology, or else they go so far in the opposite direction that it borders on comical.

But it doesn’t always have to be that way. In fact, when technology is shown properly in film it often serves as inspiration for engineers. The portrayal of facial recognition and gesture control in Minority Report was so well done that it’s still referenced today, nearly 20 years after the film’s release. For all its faults, Star Trek is responsible for a number of “life imitating art” creations; such as early mobile phones bearing an unmistakable resemblance to the flip communicators issued to Starfleet personnel.

So when I saw the exceptional use of 3D printing in the Netflix reboot of Lost in Space, I felt it was something that needed to be pointed out. From the way the crew made use of printed parts to the printer’s control interface, everything felt very real. It took existing technology and pushed it forward in a way that was impressive while still being believable. It was the kind of portrayal of technology that modern tech-savvy audiences deserve.

It left such an impression that we decided to reach out to Seth Molson, the artist behind the user interfaces from Lost in Space, and try to gain a little insight from somebody who is fighting the good fight for technology in media. To learn how he creates his interfaces, the pitfalls he navigates, and how the expectations of the viewer have changed now that we all have a touch screen supercomputer in our pocket.

DMCA Review: Big Win For Right To Repair, Zero For Right To Tinker

October 26, 2018 by Elliot Williams 35 Comments

This year’s Digital Millennium Copyright Act (DMCA) triennial review (PDF, legalese) contained some great news. Particularly, breaking encryption in a product in order to repair it has been deemed legal, and a previous exemption for reverse engineering 3D printer firmware to use the filament of your choice has been broadened. The infosec community got some clarification on penetration testing, and video game librarians and archivists came away with a big win on server software for online games.

Moreover, the process to renew a previous exemption has been streamlined — one used to be required to reapply from scratch every three years and now an exemption will stand unless circumstances have changed significantly. These changes, along with recent rulings by the Supreme Court are signs that some of the worst excesses of the DMCA’s anti-circumvention clause are being walked back, twenty years after being enacted. We have to applaud these developments.

However, the new right to repair clause seems to be restricted to restoring the device in question to its original specifications; if you’d like to hack a new feature into something that you own, you’re still out of luck. And while this review was generally favorable of opening up technology to enable fair use, they didn’t approve Bunnie Huang’s petition to allow decryption of the encryption method used over HDMI cables, so building your own HDMI devices that display encrypted streams is still out. And the changes to the 3D printer filament exemption is a reminder of the patchwork nature of this whole affair: it still only applies to 3D printer filament and not other devices that attempt to enforce the use of proprietary feedstock. Wait, what?

Finally, the Library of Congress only has authority to decide which acts of reverse engineering constitute defeating anti-circumvention measures. This review does not address the tools and information necessary to do so. “Manufacture and provision of — or trafficking in — products and services designed for the purposes of circumvention…” are covered elsewhere in the code. So while you are now allowed decrypt your John Deere software to fix your tractor, it’s not yet clear that designing and selling an ECU-unlocking tool, or even e-mailing someone the decryption key, is legal.

Could we hope for more? Sure! But making laws in a country as large as the US is a balancing act among many different interests, and the Library of Congress’s ruling is laudably clear about how they reached their decisions. The ruling itself is worth a read if you want to dive in, but be prepared to be overwhelmed in apparent minutiae. Or save yourself a little time and read on — we’ve got the highlights from a hacker’s perspective.

The Machinists’ Mantra: Precision, Thy Name Is Rigidity

October 25, 2018 by Quinn Dunki 40 Comments

“Everything is a spring”. You’ve probably heard that expression before. How deep do you think your appreciation of that particular turn of phrase really is? You know who truly, viscerally groks this? Machinists.

As I’ve blathered on about at length previously, machine tools are all about precision. That’s easy to say, but where does precision really come from? In a word, rigidity. Machine tools do a seemingly magical thing. They remove quantities of steel (or other materials medieval humans would have killed for) with a slightly tougher piece of steel. The way they manage to do this is by applying the cutting tool to the material within a setup that is so rigid that the material has no choice but to yield. Furthermore, this cutting action is extremely precise because the tool moves as little as possible while doing so. It all comes down to rigidity. Let’s look at a basic turning setup.

GE’s Engine To Reignite Civil Supersonic Flight

October 24, 2018 by Tom Nardi 110 Comments

On October 24th, 2003 the last Concorde touched down at Filton Airport in England, and since then commercial air travel has been stuck moving slower than the speed of sound. There were a number of reasons for retiring the Concorde, from the rising cost of fuel to bad publicity following a crash in 2000 which claimed the lives of all passengers and crew aboard. Flying on Concorde was also exceptionally expensive and only practical on certain routes, as concerns about sonic booms over land meant it had to remain subsonic unless it was flying over the ocean.

The failure of the Concorde has kept manufacturers and the civil aviation industry from investing in a new supersonic aircraft for fifteen years now. It’s a rare example of commercial technology going “backwards”; the latest and greatest airliners built today can’t achieve even half the Concorde’s top speed of 1,354 MPH (2,179 km/h). In an era where speed and performance is an obsession, commercial air travel simply hasn’t kept up with the pace of the world around it. There’s a fortune to be made for anyone who can figure out a way to offer supersonic flight for passengers and cargo without falling into the same traps that ended the Concorde program.

With the announcement that they’ve completed the initial design of their new Affinity engine, General Electric is looking to answer that call. Combining GE’s experience developing high performance fighter jet engines with the latest efficiency improvements from their civilian engines, Affinity is the first new supersonic engine designed for the civil aviation market in fifty five years. It’s not slated to fly before 2023, and likely won’t see commercial use for a few years after that, but this is an important first step in getting air travel to catch up with the rest of our modern lives.

Sidney Darlington

October 23, 2018 by Dan Maloney 32 Comments

In a field where components and systems are often known by sterile strings of characters that manufacturers assign or by cutesy names that are clearly products of the marketing department and their focus groups, having your name attached to an innovation is rare. Rarer still is the case where the mere mention of an otherwise obscure inventor’s name brings up a complete schematic in the listener’s mind.

Given how rarely such an honor is bestowed, we’d be forgiven to think that Sidney Darlington’s only contribution to electronics is the paired transistor he invented in the 1950s that bears his name to this day. His long career yielded so much more, from network synthesis theory to rocket guidance systems that would eventually take us to the Moon. The irony is that the Darlington pair that made his name known to generations of engineers and hobbyists was almost an afterthought, developed after a weekend of tinkering.

That Time Atari Cracked The Nintendo Entertainment System

October 22, 2018 by Drew Littrell 45 Comments

It was darkest hour for the video game industry following the holiday shopping season of 1982. The torrent of third party developed titles had flooded the home video game console market to the point of saturation. It incited a price war amongst retailers where new releases were dropped to 85% off MSRP after less than a month on the shelves. Mountains of warehouse inventory went unsold leaving a company like Atari choosing to dump the merchandise into the Chihuahuan desert rather than face the looming tax bill. As a result, the whole home video game industry receded seemingly overnight.

One company single-handedly revived video games to mainstream prominence. That company was Nintendo. They’re ostensibly seen as the “savior” of the video games industry, despite the fact that microcomputer games were still thriving (history tends to be written by the victors). Nevertheless their Nintendo Entertainment System (NES) was an innovative console featuring games with scrolling screens, arcade-like sprites. But the tactic they used to avoid repeating the 1983 collapse was to tightly control their market using the Nintendo Seal of Quality.

From the third party developer perspective, Nintendo’s Seal of Quality represented more than just another logo to throw on the box art. It represented what you could and couldn’t do with your business. Those third party licensing agreements dictated the types of games that could be made, the way the games were manufactured, the schedule on which the games shipped to retail, and even the number of games your company could make. From the customer side of things that seal stood for confidence in the product, and Nintendo would go to great lengths to ensure it did just that.

This is the story of how an Atari subsidiary company cracked the hardware security of the original Nintendo and started putting it into their unofficial cartridges.

ILLIAC Was HAL 9000’s Granddaddy

October 18, 2018 by Al Williams 42 Comments

Science fiction is usually couched in fact, and it’s fun to look at an iconic computer like HAL 9000 and trace the origins of this artificial intelligence gone wrong. You might be surprised to find that you can trace HAL’s origins to a computer built for the US Army in 1952.

If you are a fan of the novel and movie 2001: A Space Oddessy, you may recall that the HAL 9000 computer was “born” in Urbana, Illinois. Why pick such an odd location? Urbana is hardly a household name unless you know the Chicago area well. But Urbana has a place in real-life computer history. As the home of the University of Illinois at Urbana–Champaign, Urbana was known for producing a line of computers known as ILLIAC, several of which had historical significance. In particular, the ILLIAC IV was a dream of a supercomputer that — while not entirely successful — pointed the way for later supercomputers. Sometimes you learn more from failure than you do successes and at least one of the ILLIAC series is the poster child for that.

The Urbana story starts in the early 1950s. This was a time when the 1945 book “First Draft of a Report on the EDVAC” was sweeping through the country from its Princeton origins. This book outlined the design and construction of the Army computer that succeeded ENIAC. In it, Von Neumann proposed changes to EDVAC that would make it a stored program computer — that is, a computer that treats data and instructions the same.
