The Great Windows 11 Computer Extinction Experiment

June 29, 2021 by Jenny List 294 Comments

There was a time when a new version of Windows was a really big deal, such the launch of Windows 95 for which the tones of the Rolling Stones’ Start me up could be heard across all manner of media outlets. Gradually over years this excitement has petered out, finally leaving us with Windows 10 that would, we were told, be the last ever version of the popular operating system and thence only receive continuous updates

But here we are in 2021, and a new Windows has been announced. Windows 11 will be the next latest and greatest from Redmond, but along with all the hoopla there has been an undercurrent of concern. Every new OS comes with a list of hardware requirements, but those for Windows 11 seem to go beyond the usual in their quest to cull older hardware. Aside from requiring Secure Boot and a Trusted Platform Module that’s caused a run on the devices, they’ve struck a load of surprisingly recent processors including those in some of their current Surface mobile PCs off their supported list, and it’s reported that they will even require laptops to have front-facing webcams if they wish to run Windows 11.

chadaustin's sculpt keyboard test pads wired to protonC

Tether Tames Temperamental Typing

March 18, 2021 by Michael Shaub 6 Comments

[chadaustin] has a favorite keyboard with a great ergonomic shape, key travel distance, and size, but after switching to Windows 10, the wireless connection introduced a terrible delay. Worse yet, the receiver is notoriously susceptible to interference from USB 3.0 hubs. To provide 128-bit AES encryption, the receiver is paired with the keyboard at the factory and cannot be replaced. If you lose that, you gain a highly ergonomic paper-weight. The solution for [chadaustin] was tethering the keyboard and receive several crash-courses in hardware hacking along the way. As evidenced by the responses to this project on ycombinator, many long-time fans of the Microsoft Sculpt Ergonomic Keyboard, introduced in 2013, suffer similar issues.

We really appreciate that [chadaustin] took an incremental approach, tackling one problem at a time and getting help from others along the way for first attempts at many complex steps. The proof-of-concept involved hand-soldering each lead from the keyboard matrix’s test pads to a QMK Proton C, which worked but couldn’t fit inside the keyboard’s case. For a more permanent and tidy solution, [chadaustin] tried a ribbon-cable breakout board and other microcontrollers, but none of those were compact enough to fit inside the case either. This required a custom PCB, another first for [chadaustin].

After a one-day intro to KiCad, [chadaustin] dug into the datasheets, completed a schematic for the board, and generously shared the process of choosing components and creating the layout. [chadaustin] ordered a board and found the mounting holes’ placement needed to be shifted.

With the full matrix mapped by [johnmilkspill], flashing QMK onto the AT90USB1286 controller went fairly smoothly. [chadaustin] chose to map both sides of the split spacebar back to the space key but did add a feature by repurposing the battery indicator LED to Caps Lock. And the results?

According to testing done with Is It Snappy?, the latency dropped from the wireless 78 ms down to 65 ms over USB. More importantly, this latency is now consistent, unaffected by USB hubs, and there is no receiver to lose. Of course, [chadaustin] has ideas for future improvement, including regaining the multimedia function keys, as these kinds of hacks are never really done; they are just in the current revision. No word on the fate of the detached number pad, but that likely needs its own tether and is a project for another day.

Kinect Gave Us A Preview Of The Future, Though Not The One It Intended

November 9, 2020 by Roger Cheng 13 Comments

This holiday season, the video game industry hype machine is focused on building excitement for new PlayStation and Xbox consoles. Ten years ago, a similar chorus of hype reached a crescendo with the release of Xbox Kinect, promising to revolutionize how we play. That vision never panned out, but as [Daniel Cooper] of Engadget pointed out in a Kinect retrospective, it premiered consumer technologies that impacted fields far beyond gaming.

Kinect has since withdrawn from the gaming market, because as it turns out gamers are quite content with handheld controllers. This year’s new controllers for a PlayStation or Xbox would be immediately familiar to gamers from ten years ago. Even Nintendo, whose Wii is frequently credited as motivation for Microsoft to develop the Kinect, have arguably taken a step back with Joy-cons of their Switch.

But the Kinect’s success at bringing a depth camera to consumer price levels paved the way to explore many ideas that were previously impossible. The flurry of enthusiastic Kinect hacking proved there is a market for depth camera peripherals, leading to plug-and-play devices like Intel RealSense to make depth-sensing projects easier. The original PrimeSense technology has since been simplified and miniaturized into Face ID unlocking Apple phones. Kinect itself found another job with Microsoft’s HoloLens AR headset. And let’s not forget the upcoming wave of autonomous cars and drones, many of which will see their worlds via depth sensors of some kind. Some might even be equipped with the latest sensor to wear the Kinect name.

Inside the Kinect was also one of the earliest microphone arrays sold to consumers. Enabling the Kinect to figure out which direction a voice is coming from, and isolate it from other noises in the room. Such technology were previously the exclusive domain of expensive corporate conference room speakerphones, but now it forms the core of inexpensive home assistants like an Amazon Echo Dot. Raising the bar so much that hacks needed many more microphones just to stand out.

With the technology available more easily elsewhere, attrition of a discontinued device is reflected in the dwindling number of recent Kinect hacks on these pages. We still see a cool project every now and then, though. As the classic sensor bar itself recedes into history, others will take its place to give us depth sensing and smart audio. But for many of us, Kinect was the ambitious videogame peripheral that gave us our first experience.

Start Me Up: What Has The Windows 95 Desktop Given Us 25 Years Later?

August 31, 2020 by Jenny List 104 Comments

We’ve had something of an anniversary of late, and it’s one that will no doubt elicit a variety of reactions from our community. It’s now 25 years ago that Windows 95 was launched, the operating system that gave the majority of 1990s PC users their first taste of a desktop-based GUI and a 32-bit operating system.

To the strains of the Rolling Stones’ Start me up, Microsoft execs including Bill Gates himself jubilantly danced on stage at the launch of what was probably to become the company’s defining product, perhaps oblivious to the line “You make a grown man cry” which maybe unwittingly strayed close to the user experience when faced with some of the software’s shortcomings.

Its security may seem laughable by the standards of today and the uneasy marriage of 16-bit DOS underpinning a 32-bit Windows operating system was clunky even in its heyday, but perhaps now is the best time to evaluate it unclouded by technical prejudice. What can we see of Windows 95 in the operating systems we use today, and thus from that can we ask the question: What did Windows 95 get right?

Microsoft Releases The Source Code You Wanted Almost 30 Years Ago

May 22, 2020 by Al Williams 66 Comments

In the late 1970s and early 1980s, if you had a personal computer there was a fair chance it either booted into some version of Microsoft Basic or you could load and run Basic. There were other versions, of course, especially for very small computers, but the gold standard for home computer Basic was Microsoft’s version, known then as GW-Basic. Now you can get the once-coveted Microsoft Basic source code for the 8086/8088 directly from Microsoft in the state you would have found it in 1983. They put up a read only GW-BASIC repository, presumably to stop a flood of feature requests for GPU acceleration.

You might wonder why they would do this? It is certainly educational, especially if you are interested in assembly language. For historical reasons, you might want to get a copy you could modify, too, for your latest retrocomputer project.

There are a few tidbits of interest. Some of the source is marked that it was translated. Apparently, Microsoft had a master implementation for some processor — real or imagined — and could translate from that code to 8088, Z-80, 6502, or any other processor they wanted to target.

From what we understand, GW-Basic was identical to IBM’s BASICA, but didn’t require certain IBM PC ROMs to operate. Of course, BASICA, itself, came from MBASIC, Microsoft’s CP/M language that originated with Altair Basic. A long lineage that influenced personal computers for many years. On a side note, there’s debate on what the GW stands for. Gee-Whiz is a popular vote, but it could stand for ‘Gates, William’, Greg Whitten (an early Microsoft employee), or Gates-Whitten. The source code doesn’t appear to answer that question.

We did enjoy the 1975 copyright message, though:

ORIGINALLY WRITTEN ON THE PDP-10 FROM
FEBRUARY 9 TO APRIL 9 1975

BILL GATES WROTE A LOT OF STUFF.
PAUL ALLEN WROTE A LOT OF OTHER STUFF AND FAST CODE.
MONTE DAVIDOFF WROTE THE MATH PACKAGE (F4I.MAC).

It wasn’t long ago that Microsoft released some old versions of MSDOS. If you have the urge to write some Basic, you might pass on GW-Basic and try QB64, instead.

What Does GitHub’s Npm Acquisition Mean For Developers?

March 26, 2020 by Ben James 33 Comments

Microsoft’s open-source shopping spree has claimed another victim: npm. [Nat Friedman], CEO of GitHub (owned by Microsoft), announced the move recently on the GitHub blog.

So what motivated the acquisition, and what changes are we likely to see as a result of it? There are some obvious upsides and integrations, but these will be accompanied by the usual dose of skepticism from the open-source community. The company history and working culture of npm has also had its moments in the news, which may well have contributed to the current situation. This post aims to explore some of the rationale behind the acquisition, and what it’s likely to mean for developers in the future.

This Week In Security: Is RSA Finally Broken? The Push For Cloud Accounts, Encrypted DNS, And More Mobile Mayhem

October 4, 2019 by Jonathan Bennett 24 Comments

Ever wondered what “cyberwar” looks like? Apparently it’s a lot of guessing security questions and changing passwords. It’s an interesting read on its own, but there are some interesting clues if you read between the lines. A General in the know mentioned that Isis:

clicked on something or they did something that then allowed us to gain control and then start to move.

This sounds very similar to stories we’ve covered in the past, where 0-days are used to compromise groups or individuals. Perhaps the NSA supplied such an exploit, and it was sent in a phishing attack. Through various means, the U.S. team quietly compromised systems and collected credentials.

The article mentions something else interesting. Apparently the targets of this digital sting had also been compromising machines around the world, and using those machines to manage their efforts. The decision was made by the U.S. team to also compromise those machines, in order to lock out the Isis team. This might be the most controversial element of the story. Security researchers have wanted permission to do this for years. How should the third parties view these incursions?

The third element that I found particularly interesting was the phase 2 attack. Rather than outright delete, ban, and break Isis devices and accounts, the U.S. team installed persistent malware that emulated innocuous glitches. The internet connection is extremely laggy on certain days, certain websites simply don’t connect, and other problems. These are the sort of gremlins that networking pros spend all day trying to troubleshoot. The idea that it’s intentional gives me one more thing to worry about.
