Utah Man Builds Bulletproof Stormtrooper Suit With 3-D Printer (wtop.com) 76

schwit1 quotes CNN's report on a software engineer who really loves Star Wars costumes:
"I kind of incorporated all of the things that I've learned in 3-D printing and DIY into this project," said Nils Rasmusson. Over the course of nine months, he printed the suit and put it together. "I had to figure out — how do you put all of these pieces together? There's no tutorial or instructions on this," he said.

The helmet alone is made up of 19 different pieces fabricated on the printer. Rasmusson said he used five printers, humming for about 400 to 600 hours, to fabricate the suit out of plastic filament.

It's even bulletproof. His friend works for a company that bulletproofs cars...

Coming Soon: an Open Source eBook Reader (gizmodo.com.au) 46

Electronic component distributor Digi-Key will be producing a small manufacturing run of the "open hardware" ereader from the Open Book Project, reports Gizmodo: The raw hardware isn't as sleek or pretty as devices like the Kindle, but at the same time there's a certain appeal to the exposed circuit board which features brief descriptions of various components, ports, and connections etched right onto the board itself for those looking to tinker or upgrade the hardware. Users are encouraged to design their own enclosures for the Open Book if they prefer, either through 3D-printed cases made of plastic, or rustic wooden enclosures created using laser cutting machines. With a resolution of just 400x300 pixels on its monochromatic E Ink display, text on the Open Book won't look as pretty as it does on the Amazon Kindle Oasis which boasts a resolution of 1,680x1,264 pixels, but it should barely sip power from its built-in lithium-polymer rechargeable battery -- a key benefit of using electronic paper.

The open source ereader -- powered by an ARM Cortex M4 processor -- will also include a headphone jack for listening to audio books, a dedicated flash chip for storing language files with specific character sets, and even a microphone that leverages a TensorFlow-trained AI model to intelligently process voice commands so you can quietly mutter "next!" to turn the page instead of reaching for one of the ereader's physical buttons like a neanderthal. It can also be upgraded with additional functionality such as Bluetooth or wifi using Adafruit Feather expansion boards, but the most important feature is simply a microSD card slot allowing users to load whatever electronic text and ebook files they want. They won't have to be limited by what a giant corporation approves for its online book store, or be subject to price-fixing schemes which, for some reason, have still resulted in electronic files costing more than printed books.

Building Your Own Open Source, Privacy-Protecting Voice Assistant With A Raspberry Pi (pcmag.com) 42

PC Magazine's "tech nerd" Whitson Gordon writes that "Once you start using a smart speaker to set reminders, play the news, or turn the lights on, it's hard to go back."

But if you want the convenience of voice control without the data-collecting tech giant behind the scenes, an open-source project called Mycroft is a great alternative. And you can run it right on a Raspberry Pi.

Mycroft is a free, open-source voice assistant designed to run on Linux-based devices... Mycroft has been around for quite a few years, but it's recently gained a bit more notoriety thanks to privacy concerns surrounding data collection at Amazon and Google. Unlike those assistants, Mycroft only collects data if you opt in during setup. And for the users who do opt in, Mycroft promises never to sell your data to advertisers or third parties -- instead, it only uses it to help developers improve the product. Mycroft even uses the privacy-focused DuckDuckGo as its search engine instead of Google when you ask for information.

Mycroft makes its own smart speaker called the Mark I, though it's currently sold out with a new Mark II (video here) on the way. However, since the project is open-source, you can install Mycroft on just about any Linux machine, including the Raspberry Pi (thanks to a pre-made build called Picroft). Using Mycroft on the Pi is free, but you can also subscribe to a $1.99-per-month plan to help support its development -- you'll even get a few goodies, like other voices that sound more lifelike than the default robotic voice.

'How I Compiled My Own SPARC CPU In a Cheap FPGA Board' (www.thanassis.space) 83

Long-time Slashdot reader ttsiod works for the European Space Agency as an embedded software engineer. He writes: After reading an interesting article from an NVIDIA engineer about how he used a dirt-cheap field-programmable gate array board to code a real-time ray-tracer, I got my hands on the same board -- and "compiled" a dual-core SPARC-compatible CPU inside it... Basically, the same kind of design we fly in the European Space Agency's satellites.

I decided to document the process, since there's not much material of that kind available. I hope it will be an interesting read for my fellow Slashdotters -- showcasing the trials and tribulations faced by those who prefer the Open-Source ways of doing things... Just read it and you'll see what I mean.

This is the same Slashdot reader who in 2016 reverse engineered his Android tablet so he could run a Debian chroot inside it. "Please remember that I am a software developer, not a HW one," his new essay warns.

"I simply enjoy fooling around with technology like this."

Biohackers Use a Raspberry Pi to Implant a Networked Hard Drive (the-parallax.com) 118

"Biohackers took one small but important step toward the science fiction dystopia depicted in William Gibson's Johnny Mnemonic," reports The Parallax, in an article shared by a Slashdot reader: The Four Thieves Vinegar biohacking collective has not figured out how to precisely mimic the memory data transfer scenario Gibson conjured, but it has built a device to enable people to store and transfer data wirelessly in their bodies. Using off-the-shelf parts and focused efforts, the biohacking group has designed and built a networked hard drive, coated in a biosafe resin, to be subcutaneously implanted in the human body. It's powered by an external battery that connects to the device via an induction coil, and its storage capacity is limited only by the size of the microSD card it contains. Michael Laufer, who founded Four Thieves Vinegar, calls it the Pegleg.

In the small hours of August 8, in an operating room within the small house, two patients received the second version of the Pegleg implant, which Laufer says is the world's first subcutaneous networked drive... To make Pegleg v2, Laufer and his team removed from the Raspberry Pi both Micro USB connectors (one for power, one for data), the Mini HDMI connector, and the camera connector. They then soldered on a second Wi-Fi chip to enable it to transfer data to another Pegleg and allow other devices to connect to it, as well as an induction coil to enable it to be powered by a wireless battery resting in a contiguous sports armband or pants pocket. They enabled Bluetooth for future functionality, inserted a 512GB microSD card for storage, and updated the firmware. Finally, they coated the hacked device in a biocompatible acrylic resin to prevent it from interacting with the recipient's body and to diffuse the heat it emanates.

At 11:44 a.m. on the same day, Laufer -- an implant newbie who has three small tattoos but no piercings -- took a seat in the surgical room... During the procedure, Laufer passed out for a few seconds and vomited a little bit. But 32 minutes later, he had a functional "Pegleg" implant.

'Mining Bitcoin On a 1983 Apple II: a Highly Impractical Guide' (retroconnector.com) 42

option8 ((Slashdot reader #16,509) writes: TL;DR: Mining Bitcoin on a 1MHz 8-bit processor will cost you more than the world's combined economies, and take roughly 256 trillion years.
"But it could happen tomorrow. It's a lottery, after all," explains the blog post (describing this mad scientist as a hardware hacker and "self-taught maker", determined to mine bitcoin "in what must be the slowest possible way. I call it 8BITCOIN....")

There's also a Twitch.TV stream, with some appropriate 8-bit music, and the blog post ends by including his own bitcoin address, "If you feel like you absolutely must throw some money at me and this project."

"Upon doing some research, I found that, not only were other 8-bit platforms being put to the task, but other, even more obscure and outdated hardware. An IBM 1401 from the 1960s, a rebuilt Apollo Guidance Computer, and even one deranged individual who demonstrated the hashing algorithm by hand. It turns out, those examples all come from the same deranged individual, Ken Shirriff."

Microsoft Claims Unauthorized Repairing of Its Devices Would Be a Security Risk (securepairs.org) 84

In comments submitted to America's Federal Trade Commission, Microsoft says repairing its devices could jeopardize protections from the Trusted Platform Module (TPM) security chip.

"Don't believe them," argues a group of information security professionals who support the right to repair. Slashdot reader chicksdaddy quotes their report: The statement was submitted ahead of Nixing the Fix, an FTC workshop on repair restrictions that is scheduled for mid-July... "The unauthorized repair and replacement of device components can result in the disabling of key hardware security features or can impede the update of firmware that is important to device security or system integrity," Microsoft wrote... "If the TPM or other hardware or software protections were compromised by a malicious or unqualified repair vendor, those security protections would be rendered ineffective and consumers' data and control of the device would be at risk. Moreover, a security breach of one device can potentially compromise the security of a platform or other devices connected to the network...."

As we know: Firms like Microsoft, Lexmark, LG, Samsung and others use arguments like this all the time and then not too subtly imply that their authorized repair professionals are more trustworthy and honest than independent competitors. But that's just hot air. They have no data to back up those assertions and there's no way that their repair technicians are more trustworthy than owners, themselves...

There's nothing inherent in repair or the things called for in right to repair laws like providing diagnostic software, diagnostic codes, schematics and replacement parts that puts the integrity of the TPM or the trust model it anchors at risk. Nor does the TPM require that the devices it secures remain pristine: using the same hardware and software configuration as when they were sold by the OEM. After all, TPMs are in Dell computers. Dell makes diagnostic software and diagnostic codes and schematics available for their hardware and I haven't heard Microsoft or anybody else suggest that a TPM on a repairable Dell laptop is any less secure than the TPM on an unrepairable Microsoft Surface.

Microsoft's Chromium Edge Browser Now Available On Windows 7 and Windows 8 (theverge.com) 58

The Chromium-powered Edge browser is now available on both Windows 7 and Windows 8 for testing today. The Verge reports: The release comes two months after Chromium Edge first debuted on Windows 10, and a month after it appeared on macOS. Microsoft is releasing the daily Canary builds initially, and plans to support the weekly Dev channel "soon." You can download the installer over at Microsoft's Edge Insider site. "You will find the experience and feature set on previous versions of Windows to be largely the same as on Windows 10, including forthcoming support for Internet Explorer mode for our enterprise customers," explains a Microsoft Edge team blog post. While most features will be the same, dark mode is missing and Microsoft says there is no support for AAD sign-in.

Microsoft's Plan To Split OS From Shell Takes Shape (zdnet.com) 128

An anonymous reader quotes a report from ZDNet: The latest Windows preview from the 20H1 branch, build 18917, has some hidden components that signal a future where the Windows Shell UI parts, such as Action Center, will be separate from the rest of Windows and can be updated with shell packages. A developer who uses the Twitter handle Albacore gave a breakdown of a new component in Build 18917 called 'Shell Update Agent,' which he notes is "capable of obtaining and updating the shell on demand."

That capability may mean nothing to most Windows 10 users. However, for Windows watchers it could be an interesting development of Microsoft's unannounced plans for Windows Core OS, in which Windows is modularized and calls on a range of shells that target different form factors, from HoloLens to Surface and dual-screen devices like the recently revealed Centaurus laptop, whose shell is called Santorini. Albacore goes on to explain that the Shell Update Agent references 'Package Family Names,' which suggests that the "shell will indeed be a separate, packaged component." Those shell packages can be acquired from both external and internal sources, which could mean shell components like the Start Menu, Action Center and Taskbar could be selectively built, based on these acquired packages. Finally, one more shell-related change noted relates to a new method for syncing settings. "The new one should support syncing more advanced and previously 'legacy' options such as File Explorer configuration," Albacore notes.

Maker Faire and Make Magazine Have Laid Off All Staff and Paused All Operations (techcrunch.com) 117

McGruber quotes TechCrunch: Maker Media Inc ceased operations this week and let go of all of its employees — about 22 employees" founder and CEO Dale Dougherty told TechCrunch. "I started this 15 years ago and it's always been a struggle as a business to make this work. Print publishing is not a great business for anybody, but it works . . . barely. Events are hard . . . there was a drop off in corporate sponsorship." Microsoft and Autodesk failed to sponsor this year's flagship Bay Area Maker Faire.

But Dougherty is still desperately trying to resuscitate the company in some capacity, if only to keep MAKE:'s online archive running and continue allowing third-party organizers to license the Maker Faire name to throw affiliated events. Rather than bankruptcy, Maker Media is working through an alternative Assignment for Benefit of Creditors process.

"We're trying to keep the servers running" Dougherty tells me. "I hope to be able to get control of the assets of the company and restart it. We're not necessarily going to do everything we did in the past but I'm committed to keeping the print magazine going and the Maker Faire licensing program." The fate of those hopes will depend on negotiations with banks and financiers over the next few weeks. For now the sites remain online.

Microsoft Teases Its Edge Browser For macOS (theverge.com) 76

In a blog post detailing new features coming to Edge, Microsoft has started teasing what Edge will look like on macOS. The Verge reports: During the company's Build 2019 developer conference, Microsoft is announcing new features for Edge on Windows and teasing the upcoming macOS release. We understand that the release will be available very soon, and Mac users should be able to access both the Canary and Dev builds of Edge just like Windows. Microsoft's implementation of Chromium on Edge has so far seen good performance improvements and reliability on Windows. It's not clear if we'll see similar improvements on the macOS side versus Chrome, but at least it gives Mac users another Chromium option with some Microsoft services and sync integration. MacRumors notes that Edge "will be Microsoft's first web browser on the Mac since Internet Explorer received its last feature update nearly 16 years ago."

Can You Build Your Own Mac? (vice.com) 315

"If you're sick of MacBooks but love MacOS, be brave and convert a new laptop into a Hackintosh with our exhaustive guide," writes Motherboard, in an article shared by eatmorekix: Perhaps it's the fact that Apple solders on all of its main parts on its laptops. Perhaps it's the inability for users to repair or upgrade their own machines. Maybe it's the keyboard. For whatever reason, laptops are looking mighty attractive for Hackintoshing these days, despite the knotty qualms some people have with it...

As frustrated by the keyboard and the price as by the fact that nothing was upgradeable on the current generation of MacBook Pros, I went on this journey myself a year ago -- and made it out on the other side much more knowledgeable about why MacOS is a great, quite flexible operating system, often (and unfortunately) placed in a not-so-perfect machine.

It's a long read, but it ends with the author saying he "gained a great appreciation for the process" and ended up with "a fairly stable machine that can handle much of what Apple's own offerings can -- without the incredibly high price to boot."

Despite the (many) technical challenges, "enough of the things that make MacOS worth installing work, and you can make a good weekend project out of this and get a good machine in the end -- one with better specs and more upgradability than many of Apple's own products."

Microsoft Takes a Big Step Towards Putting Xbox Games On Windows (arstechnica.com) 87

An anonymous reader quotes a report from Ars Technica, written by Peter Bright: Ever since the first Xbox was released, an obvious question has been hanging in the air: Microsoft already owns one of the premier gaming platforms, the PC, and both the original Xbox and the current Xbox One are more or less PCs anyway, so when is Microsoft going to bring the two together and let us play Xbox games on Windows? With the new Windows 10 builds, it looks like the company is taking some big steps in that direction. Microsoft has put big chunks of the Xbox infrastructure into Windows 10. This starts right from the moment you download the game: it's coming from the Xbox distribution servers, not the usual ones for Store apps. The game package itself uses a format called .xvc, which is used for Xbox One games, and there are PowerShell commands to work with these .xvc files and install .xvc games. Microsoft Gaming Services includes portions of this Xbox infrastructure; it includes a couple of drivers ("Microsoft Gaming Filesystem Driver" and "Microsoft Gaming Install Filter Driver"), along with a number of libraries that provide Xbox APIs.

The last few Windows 10 preview builds have included some vague instructions from Microsoft to install a special edition of a game, State of Decay, and report any problems with the process. There are no problems with playing the game but, rather, problems with installing and launching it. The instructions didn't give any indication as to why or what to look for. Naturally, people have been taking a closer look to see what's special about State of Decay and figure out why Microsoft is having Windows Insiders test it. Nazmus Khandaker, Rafael Rivera, and the pseudonymous WalkingCat have been poking around both the special edition of State of Decay and a helper application called Microsoft Gaming Services that insider machines are running. Brad Sams wrote up his findings. [...] The State of Decay package does nonetheless contain PC-oriented elements. In particular, it tries to install and update the DirectX runtime during its setup. We the users don't seem to be at the stage of simply running Xbox games unmodified on our PCs, or at least, not yet. But it looks as if the groundwork is being laid. The strange preview of a 2020 Windows release looks like it contains even more of this infrastructure, with signs of a layer to support Xbox's Direct3D variant on PC.
"Microsoft could go the whole hog and simply make a Windows 10 PC with a suitable hardware spec into an Xbox that can play any Xbox game," writes Bright, adding: "it might just be there as a simple option for developers to enable if they choose."

Vox Lawyers Briefly Censored YouTubers Who Mocked the Verge's Bad PC Build Video (arstechnica.com) 161

An anonymous reader writes: In case you missed the latest drama to take place in the YouTube tech community, Ars Technica reports how Vox Media attempted to copyright strike two reaction videos that mocked The Verge's terrible PC build guide video that could have ruined a $2,000 system for a beginner PC builder. That effort failed when the tech community sounded the alarms; YouTube removed the copyright strikes and Vox Media had to retract their takedown notice.

From the report: "Last week, The Verge got a reminder about the power of the Streisand effect after its lawyers issued copyright takedown requests for two YouTube videos that criticized -- and heavily excerpted -- a video by The Verge. Each takedown came with a copyright 'strike.' It was a big deal for the creators of the videos, because three 'strikes' in a 90-day period are enough to get a YouTuber permanently banned from the platform. T.C. Sottek, the Verge's managing editor, blamed lawyers at the Verge's parent company, Vox Media, for the decision. 'The Verge's editorial structure was involved zero percent in the decision to issue a strike,' Sottek said in a direct message. 'Vox Media's legal team did this independently and informed us of it after the fact.' The move sparked an online backlash. Verge editor Nilay Patel (who, full disclosure, was briefly a colleague of mine at The Verge's sister publication Vox.com), says that when he learned about the decision, he asked that the strike be rescinded, leading to the videos being reinstated. Still, Patel defended the lawyers' legal reasoning, arguing that the videos 'crossed the line' into copyright infringement. It's hard to be sure if this is true since there are very few precedents in this area of the law. But the one legal precedent I was able to find suggests the opposite: that this kind of video is solidly within the bounds of copyright's fair use doctrine."

Microsoft Making More of the Windows 10 Built-In Apps Removable (arstechnica.com) 82

With the latest Windows 10 build 18262, Microsoft is allowing you to remove apps such as Mail, Calendar, Movies & TV, and the Groove Music app. Ars Technica reports: The ability to remove these apps doesn't really mean much in terms of disk space or convenience, as none of them are very big. The move may be of more interest to corporate deployments; an organization that has standardized on Outlook, for example, might want to remove the Mail and Calendar apps to reduce user confusion.

Elsewhere, the new build also updates Task Manager; an optional column in the Details tab will show which applications handle mixed DPI systems and what API level they use for that support. Microsoft is also planning, but has not yet enabled, a new Windows troubleshooter. This will examine diagnostic data and automatically perform any fixes or reconfigurations that appear to be necessary.

Microsoft Removes 'Sets' Tabbed Windows Feature From Next Release (groovypost.com) 133

The much-anticipated Sets feature has been pulled from the newest Windows 10 Redstone 5 build and there's no word when it will return. As groovyPost reports, "The Sets feature is a tabbed-windows experience that lets you group together different apps on your desktop." It's like having different tabs open in your browser, but for apps and File Explorer. From the report: Details on why it was removed and when it will come back have been vague. Microsoft made the announcement about Sets in [yesterday's] blog post about preview build 17704: "Thank you for your continued support of testing Sets. We continue to receive valuable feedback from you as we develop this feature helping to ensure we deliver the best possible experience once it's ready for release. Starting with this build, we're taking Sets offline to continue making it great. Based on your feedback, some of the things we're focusing on include improvements to the visual design and continuing to better integrate Office and Microsoft Edge into Sets to enhance workflow. If you have been testing Sets, you will no longer see it as of today's build, however, Sets will return in a future WIP flight. Thanks again for your feedback."

Rebuilding the PDP-11/70 with a Raspberry Pi (wixsite.com) 96

"You could look at this as a smallish PDP-11/70, built with modern parts," Oscar Vermeulen writes on his site. "Or alternatively, and equally valid, as a fancy front panel case for a Raspberry Pi."

Long-time Slashdot reader cptnapalm writes: Oscar Vermeulen's PiDP-11 front panel, modeling a PDP-11/70 in all its colorful glory, has been released to beta testers.

Microsoft Is Moving Kinect to the Cloud (theverge.com) 37

At the annual Build conference, Microsoft's CEO Satya Nadella announced that Kinect is moving to the cloud. "Kinect, when we first launched it in 2010, was a speech-first, gaze-first, vision-first device. It was used in gaming, and then, later on, it came to the PC, and it was used in many applications: medical, industrial, robotics, education," said Nadella. "We've been inspired by what developers have done, and since Kinect, we've made a tremendous amount of progress when it comes to some of the foundational technologies in HoloLens. So we're taking those advances and packaging them up as Project Kinect for Azure." The Verge reports: It's big news after the depth camera and microphone accessory that originally debuted on the Xbox 360 was basically declared dead last October when Microsoft stopped manufacturing it. Alex Kipman, a technical fellow at Microsoft, explained in a LinkedIn blog post that Project Kinect for Azure would combine the depth sensor with Azure AI services that could help developers make devices that will be more precise "with less power consumption." Kipman also notes that AI deep learning on depth images could lead to "cheaper-to-deploy AI algorithms" that require smaller networks to operate.
