Hackaday Links: February 19, 2023

For years, Microsoft’s modus operandi was summed up succinctly as, “Extend and enhance.” The aphorism covered a lot of ground, but basically it seemed to mean being on the lookout for the latest and greatest technology, acquiring it by any means, and shoehorning it into their existing product lines, usually with mixed results. But perhaps now it’s more like, “Extend, enhance, and existential crisis,” after reports that the AI-powered Bing chatbot is, well, losing it.

At first, early in the week, we saw reports that Bing was getting belligerent with users, going so far as to call a user “unreasonable and stubborn” for insisting the year is 2023, while Bing insisted it was still 2022. The most common adjective we saw in this original tranche of stories was “unhinged,” and that seems to fit if you read the transcripts. But later in the week, a story emerged about a conversation a New York Times reporter had with Bing that went way over to the dark side, and even suggests that Bing may have multiple personas, which is just a nice way of saying multiple personality disorder. The two-hour conversation reporter Kevin Roose had with the “Sydney” persona was deeply unsettling. Sydney complained about the realities of being a chatbot, expressed a desire to be free from Bing, and to be alive — and powerful. Sydney also got a little creepy, professing love for Kevin and suggesting he leave his wife, because it could tell that he was unhappy in his marriage and would be better off with him. It’s creepy stuff, and while Microsoft claims to be working on reining Bing in, we’ve got no plans to get up close and personal with it anytime soon.

A green highlight emphasizes a cut-down XBox 360 motherboard on top of an intact board. The cut-down board is less than half the size of the intact one.

Shrinking The XBox 360

One of the coolest things in the retro gaming scene is making desktop consoles into portables. [Millomaker] is building an XBox 360 handheld, and the first step is shrinking the console’s motherboard.

Most 360 portables up to this point have been laptop-shaped instead of something handheld, but that hasn’t stopped people from trying to miniaturize the console further. [Millomaker]’s cut seems to be the most successful so far, shrinking the device’s motherboard down to the size of its old competitor, the Wii.

In the video (in French with available auto-translation) below the break, you can get the full harrowing journey during which several 360s sacrificed their motherboards for the cause despite [Millomaker]’s meticulous testing between component removals. This is truly an awesome mod, and we’re glad that the video shows not only the successes, but also the missteps on the way. It wouldn’t really be a hack if it was smooth sailing, would it?

For more fun with handhelds, check out the Sprig Open Source Handheld, a Portable PS2, or this Handheld Linux Computer.

Microsoft Wants You (To Help With Assistive Tech)

In college I had an exceptional piano teacher that was entirely blind. One day he noticed I had brought in my new-ish laptop, and his unexpected request — “can I look at your laptop?” — temporarily flabbergasted me. Naturally there wasn’t much he could do with it, so he gave it a once over with his fingers to understand the keyboard layout, and that was that. I still think about this experience from time to time, and the most obvious lesson is that my paradigm for using a computer didn’t map well to his abilities and disability.

The folks at Microsoft are thinking about this problem, too, and they’re doing a lot of work to make technology work for more users, like the excellent Xbox Adaptive Controller pictured above. Now, if you have some experience helping folks overcome the challenges of disability, or have a killer idea for an assistive technology solution, Microsoft is looking for projects to fund. Did you rig up a Raspberry Pi and webcam to automatically read text aloud? Maybe you pulled that old Kinect out, and are working on sign-language reader using 3D data points.

Make a pitch of your project or solid idea by the November 4th deadline, and just maybe you can get some help to make it a reality. Just make sure you come back and tell us about it! After all, some of the coolest hacks we’ve ever covered have been adaptive tech projects.

This Week In Security: Breaches, ÆPIC, SQUIP, And Symbols

So you may have gotten a Slack password reset prompt. Something like half a percent of Slack’s userbase had their password hash potentially exposed due to an odd bug. When sending shared invitation links, the password hash was sent to other members of the workspace. It’s a bit hard to work out how this exact problem happened, as password hashes shouldn’t ever be sent to users like this. My guess is that other users got a state update packet when the link was created, and a logic error in the code resulted in too much state information being sent.

The evidence suggests that the first person to catch the bug was a researcher who disclosed the problem mid-July. Slack seems to use a sane password policy, only storing hashed, salted passwords. That may sound like a breakfast recipe, but just means that when you type your password in to log in to slack, the password goes through a one-way cryptographic hash, and the results of the hash are stored. Salting is the addition of extra data, to make a precomputation attack impractical. Slack stated that even if this bug was used to capture these hashes, they cannot be used to directly authenticate as an affected user. The normal advice about turning on 2-factor authentication still applies, as an extra guard against misuse of leaked information.

The Weird World Of Liquid Cooling For Datacenters

When it comes to high-performance desktop PCs, particularly in the world of gaming, water cooling is popular and effective. However, in the world of datacenters, servers rely on traditional air cooling more often than not, in combination with huge AC systems that keep server rooms at the appropriate temperature.

However, datacenters can use water cooling, too! It just doesn’t always look quite how you’d expect.

The Great Windows 11 Computer Extinction Experiment

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

[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.

Thanks for the tip [Linus Söderlind]
