'Mycroft' Open-Source Voice Assistant Out of Funds, Can't Fulfill Remaining Kickstarter Rewards (kickstarter.com) 46

In 2019 Slashdot covered Mycroft, an open-source voice assistant for Linux-based devices (including Raspberry Pi boards). But this week the company's CEO posted on Kickstarter that "without immediate new investment, we will have to cease development by the end of the month....

"We will still be shipping all orders that are made through the Mycroft website, because these sales directly cover the costs of producing and shipping the products. However we do not have the funds to continue fulfilling rewards from this crowdfunding campaign, or to even continue meaningful operations."

The announcement details Mycroft's long, strange trip, from a hardware-focused partner that couldn't provide stable hardware to their switch to using off-the-shelf parts — followed by supply chain disruptions (with hefty import and manufacturing fees): The best plan we could devise to fulfill the remaining campaign rewards was to use the slim margins we have on new sales to cover the increased costs of hardware production. With that plan in mind, we pushed forward and started production. We got plastic injection molds cast. We started printing custom PCBs. We engaged audio engineers to optimize the quality and volume of the sound output. We got the device FCC and CE approved. Many of these steps took multiple iterations to get right, and there are many more things that I'm glossing over. All up this costs — a lot of money. Far more than the total contributions from the campaign, which is why I personally committed so much additional funding. I could see a clear way forward that strengthened Mycroft as a project, as a business, and as a community.

So what went wrong? The single most expensive item that I could not predict was our ongoing litigation against the non-practicing patent entity that has never stopped trying to destroy us. If we had that million dollars we would be in a very different state right now.

With so much of our focus on hardware, and less funding to devote to improving our software — the quality and features available on the Mark II at launch were clearly underwhelming. It is more robust and stable than it has ever been, but this came at the cost of fewer new features. That in turn I believe has resulted in less than flattering reviews, and little mainstream coverage. The hardware itself has proven itself to be a solid base to work from, but without good reviews you get less sales, and without strong sales, the plan doesn't work.

The Woman Who Mastered IBM's 5,400-character Chinese Typewriter (fastcompany.com) 58

Fast Company's technology editor harrymcc writes: In the 1940s, IBM tried to market a typewriter capable of handling all 5,400 Chinese characters. The catch was that using it required memorizing a 4-digit code for each character. But a young woman named Lois Lew tackled the challenge and demoed the typewriter for the company in presentations from Manhattan to Shanghai.

More than 70 years later, Lew, now in her 90s, told her remarkable story to Thomas S. Mullaney for Fast Company.

Is Computer History Also a History of Physical Pains? (vice.com) 61

"Decades before "Zoom fatigue" broke our spirits, the so-called computer revolution brought with it a world of pain previously unknown to humankind," argues Laine Nooney (in a condensed version of a chapter in the 2022 book Abstractions and Embodiments: New Histories of Computing and Society.)

Slashdot reader em1ly shares its observation that "There was really no precedent in our history of media interaction for what the combination of sitting and looking at a computer monitor did to the human body..." Forty years later, what started with simple complaints about tired eyes has become commonplace experience for anyone whose work or school life revolves around a screen. The aches and pains of computer use now play an outsized role in our physical (and increasingly, our mental) health, as the demands of remote work force us into constant accommodation. We stretch our wrists and adjust our screens, pour money into monitor arms and ergonomic chairs, even outfit our offices with motorized desks that can follow us from sitting to standing to sitting again. Entire industries have built their profits on our slowly curving backs, while physical therapists and chiropractors do their best to stem a tide of bodily dysfunction that none of us opted into. These are, at best, partial measures, and those who can't afford extensive medical interventions or pricey furniture remain cramped over coffee tables or fashioning makeshift laptop raisers. Our bodies, quite literally, were never meant to work this way...

As both desktop computers and networked terminals proliferated in offices, schools, and homes over the 1980s, chronic pain became their unanticipated remainder: wrist pain, vision problems, and back soreness grew exponentially... To consider the history of computing through the lens of computer pain is to center bodies, users, and actions over and above hardware, software, and inventors. This perspective demands computer history to engage with a world beyond the charismatic object of computers themselves, with material culture, with design history, with workplace ethnography, with leisure studies... This is not the history of killer apps, wild hacks, and the coding wizards who stayed up late, but something far quieter and harder to trace, histories as intimate as they are "unhistoric": histories of habit, use, and making do. That pain in your neck, the numbness in your fingers, has a history far more widespread and impactful than any individual computer or computing innovator. No single computer changed the world, but computer pain has changed us all...

[T]he next time you experience "tired eyes," wrists tingling, neck cramps, or even the twinge of text neck, let it serve as a denaturalizing reminder that the function of technology has never been to make our lives easier, but only to complicate us in new ways. Computer-related pain, and the astounding efforts humans went to (and continue to, go to), to alleviate it, manage it, and negotiate it, provide one thread through the question of how the computer became personal. The introduction of computers into everyday routines, both at work and at home, was a historic site of vast cultural anxiety around the body.

IT'S INTERNATIONAL CAPS LOCK DAY (daysoftheyear.com) 62

bobstreo informs us that it's CAPS LOCK DAY and shares an excerpt about its history: Caps Lock Day first came to pass in the year 2000, when Derek Arnold of Iowa decided that he, like so many other internet users, had simply had enough of people using all caps to emphasize themselves on the web. So he created Caps Lock Day in the interest of poking fun at people who use this abomination of a typing style, and to finally bring some sanity to the net.

On mechanical typewriters, the Caps Lock key was first the Shift lock key. One of the earlier innovations in the use of typewriters saw a second character being added to each typebar. This caused the number of characters that a person was able to type to be doubled with the same number of keys being used. The second character was located above the first on each typebar's face, and the Shift key would cause the apparatus in its entirety to move, physically shifting the typebars position relative to the ribbon of inx. Just like in contemporary keyboards for computers today, the shifted position was used to create secondary characters and product capitals.

The invention of the Shift lock key was for the purpose of maintaining the shift operation indefinitely without continual effort. The typebars were mechanically locked in a shifted position, resulting in the upper character being typed when any key was pressed. This was also supposed to lower finger muscle pain caused by repetitive typing because it could be challenging to hold the shift down for more than two or three consecutive strokes prior to this. On mechanical typewriters, you would typically hit both Lock and Shift at the same time. After this, you press shift by itself in order to release the lock.

Microsoft's New Windows Terminal Preview Offers a Retro CRT Screen Effect (microsoft.com) 53

"The release of the Windows Terminal preview v0.8 has arrived!" announces a post on Microsoft's Command Line blog:
Search functionality has been added to the Terminal! The default key binding to invoke the search dropdown is {"command": "find", "keys": ["ctrl+shift+f"]}. Feel free to customize this key binding in your profiles.json if you prefer different key presses! The dropdown allows you to search up and down through the buffer as well as with letter case matching.
You can search through multiple tabs, reports the Verge -- and those tabs can also be resized "so you can fit more tabs into View." But they also note that Microsoft added some interesting retro-style CRT effects: If you're old enough to be a fan of CRT monitors then this one is for you. A new experimental feature will be enabled that includes the classic scan lines that you might have seen before the world switched to flat monitors and LCD technology.
To enable it just add the following code snippet to any of your profiles: "experimental.retroTerminalEffect": true

Video Leaks From Samsung's 'Artificial Human' Avatar Project Neon (theverge.com) 39

The Verge has been investigating Samsung's "artificial human" project Neon, which seems to be about creating realistic human avatars: A tweet from the project's lead and some leaked videos pretty much confirm this -- although they don't give us nearly enough information to judge how impressive Neon is. The lead of Neon, computer-human interaction researcher Paranav Mistry, tweeted this image, apparently showing one of the project's avatars. Mistry says the company's "Core R3" technology can now "autonomously create new expressions, new movements, new dialog (even in Hindi), completely different from the original captured data...."

In a recent interview, Mistry made clear he thinks "digital humans" will be a major technology in the 2020s... "While films may disrupt our sense of reality, 'virtual humans' or 'digital humans' will be reality. A digital human could extend its role to become a part of our everyday lives: a virtual news anchor, virtual receptionist, or even an AI-generated film star."

Reddit users also found the URLs for videos in the source code on Neon's home page -- and though the videos have since been removed, some of the footage has been archived and analyzed on YouTube.

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.

Microsoft's New Keyboards Have Dedicated Keys For 'Office' and Emojis (theverge.com) 122

"Microsoft's latest keyboards now include dedicated Office and emoji keys," reports the Verge: The software giant was previously experimenting with an Office key on keyboards earlier this year, and now the company is launching a new Ergonomic and slim Bluetooth Keyboard that include the dedicated button. The Office key replaces the right-hand Windows key, and it's used to launch the Office for Windows 10 app that acts as a hub for Microsoft's productivity suite. You can also use the Office key as a shortcut to launch Word, Excel, PowerPoint, and more. Office key + W opens Word for example, while Office key + X opens Excel.

Alongside the Office key, there's also a new emoji key on these new keyboards. It will launch the emoji picker inside Windows 10, but you won't be able to assign it to a specific emoji or even create shortcuts, unfortunately...

Microsoft quietly launched these new keyboards at the company's Surface hardware event last week, but they'll be available in stores on October 15th.

Is It Time To Get Rid Of The Caps Lock Key? (medium.com) 658

"At its worst, it's a waste of precious space, an annoyance, a solution to a problem that doesn't exist any more," complains Daniel Colin James, a writer, developer, and product manager. In a recent Medium essay, he called the Caps Lock key "an unnecessary holdover from a time when typewriters were the bleeding edge of consumer technology" -- and even contacted the man who invented the Caps Lock key (Doug Kerr, who had been a Bell Labs telephone engineer in the 1960s): I reached out to Doug about his invention, and he responded that while he still uses Caps Lock regularly, "we don't often today have a reason to type addresses in all caps, which was the context in which the need for the key first manifested itself to me."

I would go a step further, and say that most of us don't often have a reason to type anything in all caps today... [A] toggle with the same functionality could easily be activated in a number of different ways for those who really want to write things in all capital letters. (Say, for example, double tapping the Shift key, like how it already works on your phone.) Caps Lock is one of the largest keys on a modern keyboard, and it's in one of the best spots -- right next to the home row. It's taking up prime real estate, and it's not paying its rent any more.

Have you ever been in the middle of typing something, and then you get the uneasy feeling thaT YOU FLEW TOO CLOSE TO THE SUN AND NOW YOU HAVE TO REWRITE YOUR WORDS? You're not alone. Accidentally activating Caps Lock is such a relatable mistake that it's the introductory example for a research paper about accessibility issues with modern computer interfaces. Caps Lock is so frequently engaged unintentionally that password fields in software have to include a "Caps Lock is on" warning.

I've heard of people re-mapping their keyboards so the Caps Lock key becomes "Esc" or "Ctrl." But maybe it comes down to consumers. If you were shopping for a computer and were told that it shipped without a Caps Lock key -- would you be more or less likely to buy it?

Slashdot Asks: Can Anything Replace 'QWERTY' Keyboards? (technologyreview.com) 303

MIT Technology Review recently discussed new attempts to replace the standard 'QWERY' keyboard layout, including Tap, "a one-handed gadget that fits over your fingers like rubbery brass knuckles and connects wirelessly to your smartphone." It's supposed to free you from clunky physical keyboards and act as a go-anywhere typing interface. A promotional video shows smiling people wearing Tap and typing with one hand on a leg, on an arm, and even (perhaps jokingly) on some guy's forehead... But when I tried it, the reality of using Tap was neither fun nor funny. Unlike a conventional QWERTY keyboard, Tap required me to think a lot, because I had to tap my fingers in not-very-intuitive combinations to create letters: an A is your thumb, a B is your index finger and pinky, a C is all your fingers except the index.
The article also acknowledges the Dvorak Simplified Keyboard layout and other alternatives like the one-handed Twiddler keyboard, but argues that "neither managed to dent QWERTY's dominance." [W]hat if the future is no input interface at all? Neurable is a startup in Cambridge, Massachusetts, that's working on a way to type simply by thinking. It uses an electrode-dotted headband connected to a VR headset to track brain activity. Machine learning helps figure out what letter you're trying to select and anticipate which key you'll want next. After you select several keys, it can fill in the rest of the word, says cofounder and CEO Ramses Alcaide....

Then there's the device being built over at CTRL-Labs: an armband that detects the activity of muscle fibers in the arm. One use could be to replace gaming controllers. For another feature in the works, algorithms use the data to figure out what it is that your hands are trying to type, even if they're barely moving. CEO and cofounder Thomas Reardon, who previously created Microsoft's Internet Explorer, says this too is a neural interface, of a sort. Whether you're typing or dictating, you're using your brain to turn muscles on and off, he points out.

While a developer version will be shipped this year, Reardon "admits that it is still not good enough for him to toss his trusty mid-'80s IBM Model M keyboard, which he says still 'sounds like rolling thunder' when he types." But do any Slashdot readers have their own suggestions or experiences to share?

'Why I Use the IBM Model M Keyboard That's Older Than I Am' (yeokhengmeng.com) 220

Slashdot reader yeokm1 recently installed Linux on a 1993 PC. But in a new blog post he lists every keyboard he's owned over the last 12 years -- to explain why he's now typing on a 5.3-pound Model M keyboard from 1987 that's older than he is, "with its legendary buckling-spring switch." It'll probably last me the decades to the day that keyboards should become obsolete... It is sad that with all the advancements in computing, the one piece of equipment that we use the most to interact with our computers has regressed technologically in the name of costs. We don't usually expect to be using 30-year-old hardware on a daily productive basis but the IBM Model M keyboard is that exception.

Today, I don't really care about fancy features like great aesthetics, RGB backlights, media keys and extra USB ports. I just need something that gives me great tactile feedback, be durable, enable me to easily swap keys to fit my Programmer Dvorak layout. The Model M fits my needs perfectly.

"Really can use this as a weapon," the blog post jokes. There's even a video "to show clicky sound difference" between two different versions of the Model M -- and in true geek fashion, he even removes the casing screws to see whether the inside had rivets or bolts.

The original submission drew a tip from long-time Slashdot reader Spazmania based on his own experiences with the Model M. "The thing I most like? There are little plastic caps on the keys. When they get dirty I can pop them off and run them through the dishwasher."

We've Reached 'Peak Screen'. So What Comes Next? (wral.com) 100

An anonymous reader quotes the New York Times: We've hit what I call Peak Screen. For much of the last decade, a technology industry ruled by smartphones has pursued a singular goal of completely conquering our eyes. It has given us phones with ever-bigger screens and phones with unbelievable cameras, not to mention virtual reality goggles and several attempts at camera-glasses. Tech has now captured pretty much all visual capacity. Americans spend three to four hours a day looking at their phones and about 11 hours a day looking at screens of any kind.

So tech giants are building the beginning of something new: a less insistently visual tech world, a digital landscape that relies on voice assistants, headphones, watches and other wearables to take some pressure off our eyes. This could be a nightmare; we may simply add these new devices to our screen-addled lives. But depending on how these technologies develop, a digital ecosystem that demands less of our eyes could be better for everyone -- less immersive, less addictive, more conducive to multitasking, less socially awkward, and perhaps even a salve for our politics and social relations. Who will bring us this future? Amazon and Google are clearly big players, but don't discount the company that got us to Peak Screen in the first place. With advances to the Apple Watch and AirPods headphones, Apple is slowly and almost quietly creating an alternative to its phones... If it works, it could change everything again.

Warning that screens are insatiable vampires for your attention, the piece argues we should be using our phones more mindfully -- and exploring "less immersive ways to interact with the digital world" like Google and Amazon voice assisants.

Microsoft Re-Launches Its Classic 'IntelliMouse' (hothardware.com) 133

An anonymous reader quotes HotHardware: Every so often, a company will tap into our penchant for nostalgia. That is the case right now with Microsoft bringing back its iconic IntelliMouse, which was first introduced back in 1996... Microsoft continued to update the IntelliMouse for several years, up through 2003 when it released the IntelliMouse 3.0. The new 'Classic IntellMouse' for 2018 is based on that 15-year-old design with the same classic ergonomic look and feel, but with improved performance and features built around modern technology.

So, what exactly is different? "We improved two really important factors, the tracking sensor and the tactility and feel of the buttons. What we know our fans will see and feel is that it's the exact same shape and size of the IntelliMouse Explorer 3.0 from 2003. However, underneath the hood it's all brand-new technology, brand new mechanical engineering and brand-new structures so it's a lot more rigid than the original. The build quality is really excellent," Microsft explains.

HardOCP notes that Microsoft has also released "a fantastic Rube Goldberg machine video unveiling the mouse."

Mozilla Releases Open Source Speech Recognition Model, Massive Voice Dataset (mozilla.org) 58

Mozilla's VP of Technology Strategy, Sean White, writes: I'm excited to announce the initial release of Mozilla's open source speech recognition model that has an accuracy approaching what humans can perceive when listening to the same recordings... There are only a few commercial quality speech recognition services available, dominated by a small number of large companies. This reduces user choice and available features for startups, researchers or even larger companies that want to speech-enable their products and services. This is why we started DeepSpeech as an open source project.

Together with a community of likeminded developers, companies and researchers, we have applied sophisticated machine learning techniques and a variety of innovations to build a speech-to-text engine that has a word error rate of just 6.5% on LibriSpeech's test-clean dataset. vIn our initial release today, we have included pre-built packages for Python, NodeJS and a command-line binary that developers can use right away to experiment with speech recognition.

The announcement also touts the release of nearly 400,000 recordings -- downloadable by anyone -- as the first offering from Project Common Voice, "the world's second largest publicly available voice dataset." It launched in July "to make it easy for people to donate their voices to a publicly available database, and in doing so build a voice dataset that everyone can use to train new voice-enabled applications." And while they've started with English-language recordings, "we are working hard to ensure that Common Voice will support voice donations in multiple languages beginning in the first half of 2018."

"We at Mozilla believe technology should be open and accessible to all, and that includes voice... As the web expands beyond the 2D page, into the myriad ways where we connect to the Internet through new means like VR, AR, Speech, and languages, we'll continue our mission to ensure the Internet is a global public resource, open and accessible to all."

What Will Replace Computer Keyboards? (xconomy.com) 302

jeffengel writes:Computer keyboards will be phased out over the next 20 years, and we should think carefully about what replaces them as the dominant mode of communicating with machines, argues Android co-founder Rich Miner. Virtual reality technology and brain-computer links -- whose advocates include Elon Musk -- could lead to a "dystopian" future where people live their lives inside of goggles, or they jack directly into computers and become completely "de-personalized," Miner worries.

He takes a more "humanistic" view of the future of human-machine interfaces, one that frees us to be more expressive and requires computers to communicate on our level, not the other way around. That means software that can understand our speech, facial expressions, gestures, and handwriting. These technologies already exist, but have a lot of room for improvement.

One example he gives is holding up your hand to pause a video.

Clever Hack Fakes A Sleep Timer For Google Home (vortex.com) 50

Slashdot reader Lauren Weinstein writes: I've long been bitching about Google Home's lack of a basic function that clock radios have had since at least the middle of the last century -- the classic "sleep timer" for playing music until a specified time or until a specific interval has passed... Originally, sleep timer type commands weren't recognized at all by GH, but eventually it started admitting that the concept at least exists... Officially, GH still responds with "Sleep timer is not yet supported" when you give commands like "Stop playing in an hour"... A somewhat inconvenient but seemingly serviceable way to fake a sleep timer is now possible with Google Home. I plead guilty, it's a hack. But here we go.
The hack exploits the new "Night Mode" in the firmware, which lets you set a maximum volume for specific hours of the day, creating silent (but still-active) music streaming. "Yep, a hack, but it works," writes Lauren. "And it's the closest we've gotten to a real sleep timer on Google Home so far."

Meet The Next Major Operating System: Amazon's Alexa (zdnet.com) 168

ZDNet's editor-in-chief warns that Amazon has ambitious plans for its new Echo Plus: Amazon is making an explicit play to be the home hub because it can automatically discover and set up lights, locks, plugs, and switches without the need for additional hubs or apps. And the Alexa 'routines' feature will be able to tie all of this together by allowing you to automate a series of actions with a single voice command: saying "Alexa, good night," and having it turn off the lights, lock the door, and turn off the TV, for example. A platform that other apps and devices can connect into? This starts to sound a lot like an operating system for the home to me.

It's not just the home, either; Amazon announced a deal to make Alexa available in BMW and Mini vehicles from the middle of next year, allowing drivers to use the digital assistant to get directions, play music or control smart home devices while travelling, without having to use a separate app. Travellers will also have access to Alexa skills from third-party developers like Starbucks, allowing them to order their coffee while driving and thus skip the line. Back in January, Amazon and Ford said they were working together to allow voice commands to turn on the engine, lock or unlock the doors as well as play music and use other skills...

It's still early days but I think Alexa has a good shot at becoming one of the standard interfaces, certainly for consumers -- an operating system for the home, if not more, if the automotive tie-ups take off too. All of this will make Amazon a serious force to be reckoned with. Windows has the desktop, and Android and iOS can fight it out for the smartphone, but right now Alexa has a lock on the smart home.

A New Sampling Algorithm Could Eliminate Sensor Saturation (scitechdaily.com) 135

Baron_Yam shared an article from Science Daily: Researchers from MIT and the Technical University of Munich have developed a new technique that could lead to cameras that can handle light of any intensity, and audio that doesn't skip or pop. Virtually any modern information-capture device -- such as a camera, audio recorder, or telephone -- has an analog-to-digital converter in it, a circuit that converts the fluctuating voltages of analog signals into strings of ones and zeroes. Almost all commercial analog-to-digital converters (ADCs), however, have voltage limits. If an incoming signal exceeds that limit, the ADC either cuts it off or flatlines at the maximum voltage. This phenomenon is familiar as the pops and skips of a "clipped" audio signal or as "saturation" in digital images -- when, for instance, a sky that looks blue to the naked eye shows up on-camera as a sheet of white.

Last week, at the International Conference on Sampling Theory and Applications, researchers from MIT and the Technical University of Munich presented a technique that they call unlimited sampling, which can accurately digitize signals whose voltage peaks are far beyond an ADC's voltage limit. The consequence could be cameras that capture all the gradations of color visible to the human eye, audio that doesn't skip, and medical and environmental sensors that can handle both long periods of low activity and the sudden signal spikes that are often the events of interest.

One of the paper's author's explains that "The idea is very simple. If you have a number that is too big to store in your computer memory, you can take the modulo of the number."
