An anonymous reader quotes a report from Ars Technica: The nervous system does an astonishing job of tracking sensory information, and does so using signals that would drive many computer scientists insane: a noisy stream of activity spikes that may be transmitted to hundreds of additional neurons, where they are integrated with similar spike trains coming from still other neurons. Now, researchers have used spiking circuitry to build an artificial robotic skin, adopting some of the principles of how signals from our sensory neurons are transmitted and integrated. While the system relies on a few decidedly not-neural features, it has the advantage that we have chips that can run neural networks using spiking signals, which would allow this system to integrate smoothly with some energy-efficient hardware to run AI-based control software.

[...] There are four ways that these trains of spikes can convey information: the shape of an individual pulse, through their magnitude, through the length of the spike, and through the frequency of the spikes. Spike frequency is the most commonly used means of conveying information in biological systems, and the researchers use that to convey the pressure experienced by a sensor. The remaining forms of information are used to create something akin to a bar code that helps identify which sensor the reading came from. In addition to registering the pressure, the researchers had each sensor send a "I'm still here" signal at regular time intervals. Failure to receive this would be an indication that something has gone wrong with a sensor.

The spiking signals allow the next layer of the system to identify any pressure being experienced by the skin, as well as where it originated. This layer can also do basic evaluation of the sensory input: "Pressure-initiated raw pulses from the pulse generator accumulated in the signal cache center until a predefined pain threshold is surpassed, activating a pain signal." This can allow the equivalent of basic reflex reactions that don't involve higher-level control systems. For example, the researchers set up a robotic arm covered with their artificial skin, and got it to move the arm whenever it experiences pressure that can cause damage. The second layer also combines and filters signals from the skin before sending the information on to the arm's controller, which is the equivalent of the brain in this situation. So, the same system caused a robotic face to change expressions based on how much pressure its arm was sensing.

[...] The skin is designed to be assembled from a collection of segments that can snap together using magnetic interlocks. These automatically link up any necessary wiring, and each segment of skin broadcasts a unique identity code. So, if the system identifies damage, it's relatively easy for an operator to pop out the damaged segment and replace it with fresh hardware, and then update any data that links the new segment's ID with its location. The researchers call their development a neuromorphic robotic e-skin, or NRE-skin. "Neuromorphic" as a term is a bit vague, with some people using it to mean a technology that directly follows the principles used by the nervous system. That's definitely not this skin. Instead, it uses "neuromorphic" far more loosely, with the operation of the nervous system acting as an inspiration for the system.The findings have been published in the journal PNAS.

Brave Browser version 1.75 introduces "custom scriptlets," a new feature that allows advanced users to inject their own JavaScript into websites for enhanced customization, privacy, and usability. The feature is similar to the TamperMonkey and GreaseMonkey browser extensions, notes BleepingComputer. From the report: "Starting with desktop version 1.75, advanced Brave users will be able to write and inject their own scriptlets into a page, allowing for better control over their browsing experience," explained Brave in the announcement. Brave says that the feature was initially created to debug the browser's adblock feature but felt it was too valuable not to share with users. Brave's custom scriptlets feature can be used to modify webpages for a wide variety of privacy, security, and usability purposes.

For privacy-related changes, users write scripts that block JavaScript-based trackers, randomize fingerprinting APIs, and substitute Google Analytics scripts with a dummy version. In terms of customization and accessibility, the scriptlets could be used for hiding sidebars, pop-ups, floating ads, or annoying widgets, force dark mode even on sites that don't support it, expand content areas, force infinite scrolling, adjust text colors and font size, and auto-expand hidden content.

For performance and usability, the scriptlets can block video autoplay, lazy-load images, auto-fill forms with predefined data, enable custom keyboard shortcuts, bypass right-click restrictions, and automatically click confirmation dialogs. The possible actions achievable by injected JavaScript snippets are virtually endless. However, caution is advised, as running untrusted custom scriptlets may cause issues or even introduce some risk.

9to5Google's Ben Schoon reports: Google has introduced a new feature on iOS that injects links on third-party websites that take users back to Google Search. Recently, Google announced new "Page Annotations" within the Google app on iOS. This feature, as Google explains, "extracts interesting entities from the webpage and highlights them in line." Effectively, it creates links on a website that you've opened through Google's browser that the website's owner did not put there. The links, when clicked, then perform a search on Google for that subject and open the search in a pop-up window on top of the third-party website.

The feature, Google says, will offer an opt-out for website owners through a form. It's pointed out by SERoundTable that opting out can take up to 30 days, while the feature is live now. Further reading: US Says Google Is an Ad Tech Monopolist, in Closing Arguments

Privacy-focused firm DuckDuckGo has released a public beta of its browser for Windows, offering more default privacy protections and an assortment of Duck-made browsing tools. From a report: Like its Mac browser, DuckDuckGo (DDG) uses "the underlying operating system rendering API" rather than its own forked browser code. That's "a Windows WebView2 call that utilizes the Blink rendering engine underneath," according to DuckDuckGo's blog post. Fittingly, the browser reports itself as Microsoft Edge at most header-scanning sites. Inside the DuckDuckGo browser, you'll find:

1. Duck Player, which shows (most) YouTube videos "without privacy-invading ads" and doesn't feed your recommendations
2. Tracker blocking that DDG cites as "above and beyond" other browsers, including third-party tracker loading
3. Enforced encryption
4. The "fire button" that instantly closes all tabs and clears website data
5. Cookie pop-up management, automatically selecting a private option and hiding "I accept" pop-ups
6. Email protection, making it easier to use an auto-forwarding duck.com address on web forms

Apple has released the first trailer for its movie Tetris, which tells the extraordinary true story of the struggle between Western publishers, Nintendo, and the Soviet Union itself for the rights to Alexey Pajitnov's classic puzzle game. Polygon reports: Taron Egerton plays Henk Rogers, the gaming entrepreneur who was instrumental in discovering Tetris and securing the console gaming rights, thus enabling its release on Nintendo's then-revolutionary Game Boy handheld. To do so, he had to negotiate directly with the Soviet regime, since Communist law dictated that the game belonged to the people of the Soviet Union (read: the government) rather than Pajitnov himself. All sorts of Cold War skullduggery ensued.

It's an incredible tale that forms the centerpiece of David Sheff's classic book Game Over, which chronicles Nintendo's early rise. The film, directed by Jon S. Baird, seems to take a pretty broad approach to the material, drenching it in '80s pop needle drops, car chases (for some reason), retro game effects reminiscent of the dreadful Adam Sandler vehicle Pixels, and Egerton tearing up as he describes "the perfect game." [...] Tetris will stream on Apple TV Plus from March 31.

Apple says it goes out of its way to protect the safety and security of its young users. The App Store of 2019 tells a different story. Laura June, writing for InputMag: One of the most insidious forms of abuse on modern content platforms is the way unknown creators can co-opt well-known characters. Off-brand Spider-Man and fake Elsa and Anna pop up all over YouTube. I discovered this the hard way two years ago, when I found my daughter watching fake Peppa Pig videos on YouTube, many of them horrific and violent, and preying on the very young (Peppa Pig is a very popular television show for preschoolers). But YouTube, unlike Apple's App Store, is a platform where pretty much anyone can upload anything. And Google, which owns YouTube, doesn't peacock on stage like Tim Cook does, looking down his nose at Facebook and other companies for their lax attitudes on user safety. Given Apple's reputation, it was with some surprise that I found myself in a very similar position several weeks ago, while browsing Apple's App Store for games for my nearly 6-year-old daughter.

[...] Keep in mind, I was not looking for fakes. I fully expected to find only official apps for these company's characters. I didn't expect to find Paw Puppy Smashy Patrol in the store above the official Nickelodeon app PAW Patrol Pup Rescue Pack. Some apps boldly use the official Disney characters in their titles, literally advertising themselves with the copyrighted, intellectual property of a currently airing Disney show. But even the ones that aren't using Disney names in their titles depict characters that look nearly identical to Vampirina, Elsa and Anna, Sofia the First, and so on. The quality of the design varies, but some of them really do feature characters who look exactly like the ones you've come to know and trust (even if they've not-so-cleverly disguised themselves with names like Paw Puppy Smashy Patrol and Ice Queen Adventure). The apps are designed to fool you; fooling you is the goal. They're designed to make you think, "Oh right, Disney! We love Disney, we trust Disney. Let me download that for you, kid!"

Following Philadelphia's lead, San Francisco became the second major U.S. city to ban cashless businesses in a Tuesday vote by the city Board of Supervisors. The legislation ends a practice widely viewed as discriminatory against low income residents. San Francisco Examiner reports: There are currently only a handful of businesses that do not accept cash in San Francisco, requiring payment through smart phone applications tied to a person's bank account or credit card. The number, however, was increasing. Those without bank accounts or credit are unable to purchase goods in these types of stores.

"The City must remain vigilant in ensuring its economy is inclusionary and accessible to Everyone," the legislation states. "The purpose of this [law]is to ensure that all City residents -- including those who lack access to other forms of payment are able to participate in the City's economic life by paying cash for goods and many services." Businesses argue going cashless creates a safer work environment and more efficient service. Under the legislation, repeat violations would constitute a misdemeanor and carry a fine of up to $1,000. The law applies to brick-and-mortar businesses, those with a fixed location. It does not impact food trucks, ride hail services or temporary "pop up" retail.

Firefox is working on a blocker for annoying in-page alerts that often ask you to input your email address to receive a newsletter from the site. "The feature is still in the planning stages, but Mozilla is asking users for any examples of sites with annoying pop-ups," reports Android Police. "Mozilla wants to make Firefox automatically detect and dismiss the popups." From the report: If you know of sites that use in-page popups (whether it be newsletter signups, surveys, or something else), you can fill out the survey here. There are also Firefox and Chrome extensions that make the process easier. I'll be interested to see how Mozilla pulls this off, it will no doubt be difficult to detect the difference between helpful and not-helpful popups.

HughPickens.com writes: The NYT reports: "Janet N. Cook, a church secretary in Virginia, had been a widow for a decade when she joined an Internet dating site and was quickly overcome by a rush of emails, phone calls and plans for a face-to-face visit. "I'm not stupid, but I was totally naïve," says Cook, now 76, who was swept off her feet by a man who called himself Kelvin Wells and described himself as a middle-aged German businessman looking for someone "confident" and "outspoken" to travel with him to places like Italy, his "dream destination." But very soon he began describing various troubles, including being hospitalized in Ghana, where he had gone on business, and asked Cook to bail him out. In all, she sent him nearly $300,000, as he apparently followed a well-honed script that online criminals use to bilk members of dating sites out of tens of millions of dollars a year."

According to the Times internet scammers are targeting women in their 50s and 60s, often retired and living alone, who say that the email and phone wooing forms a bond that may not be physical but that is intense and enveloping. Between July 1 and Dec. 31, 2014, nearly 6,000 people registered complaints of such confidence fraud with losses of $82.3 million, according to the federal Internet Crime Complaint Center. Older people are ideal targets because they often have accumulated savings over a lifetime, own their homes and are susceptible to being deceived by someone intent on fraud. The digital version of the romance con is now sufficiently widespread that AARP's Fraud Watch Network has urged online dating sites to institute more safeguards to protect against such fraud. The AARP network recommends that dating site members use Google's "search by image" to see if the suitor's picture appears on other sites with different names. If an email from "a potential suitor seems suspicious, cut and paste it into Google and see if the words pop up on any romance scam sites," the network advised. The website romancescams.org lists red flags to look for to identify such predators, who urgently appeal to victims for money to cover financial setbacks like unexpected fines, money lost to robbery or unpaid wages. Most victims say they are embarrassed to admit what happened, and they fear that revealing it will bring derision from their family and friends, who will question their judgment and even their ability to handle their own financial affairs."It makes me sound so stupid, but he would be calling me in the evening and at night. It felt so real. We had plans to go to the Bahamas and to Bermuda together," says Louise Brown. "When I found out it was a scam, I felt so betrayed. I kept it secret from my family for two years, but it's an awful thing to carry around. But later I sent him a message and said I forgave him."

HughPickens.com writes Matt Ford writes in The Atlantic that thanks to a European Union embargo on the export of key drugs, and the refusal of major pharmaceutical companies to sell them the nation's predominant method of execution is increasingly hard to perform. With lethal injection's future uncertain, some states are turning to previously discarded methods. The Utah legislature just approved a bill to reintroduce firing squads for executions, Alabama's House of Representatives voted to authorize the electric chair if new drugs couldn't be found, and after last years botched injection, Oklahoma legislators are mulling the gas chamber.

The driving force behind the creation and abandonment of execution methods is the constant search for a humane means of taking a human life. Arizona, for example, abandoned hangings after a noose accidentally decapitated a condemned woman in 1930. Execution is also prone to problems as witnesses routinely report that, when the switch is thrown, the condemned prisoner "cringes," "leaps," and "fights the straps with amazing strength." The hands turn red, then white, and the cords of the neck stand out like steel bands. The prisoner's limbs, fingers, toes, and face are severely contorted. The force of the electrical current is so powerful that the prisoner's eyeballs sometimes pop out and "rest on [his] cheeks." The physical effects of the deadly hydrogen cyanide in the gas chamber are coma, seizures and cardiac arrest but the time lag has previously proved a problem. According to Ford one reason lethal injection enjoyed such tremendous popularity was that it strongly resembled a medical procedure, thereby projecting our preconceived notions about modern medicine—its competence, its efficacy, and its reliability—onto the capital-punishment system. "As states revert to earlier methods of execution—techniques once abandoned as backward and flawed—they run the risk that the death penalty itself will be seen in the same terms."

If you go to a sci-fi or gaming convention you'll see people in exotic "character" costumes, often holding exotic props, with some of the most popular being futuristic firearm mockups of one sort or another. Who makes all these cool fannish items? A whole bunch of artists and artisans, including Michelle Sleeper (who says she got tired of jokes about her name many years ago). She's not only one of these artisans, but is also a committed 3-D printer user, since 3-D printing is how she forms a high percentage of her props (with the word "props" being used here in the theatrical rather than the nautical sense). To keep up with what Michelle is making, you should check her blog. One of her most interesting posts, titled Atlanta Mini Maker Faire: On missing deadlines, failure, and triage, is about preparing for the event where Timothy Lord met and interviewed Michelle.

Even if gamer gatherings and SF conventions aren't your thing, the interview (along with the links above) gives a nice glimpse into the life of an independent artisan who uses technology to create a lot of her art. (Alternate Video Link)

BarbaraHudson writes Those free soft drinks at your last start-up may come with a huge hidden price tag. The Toronto Sun reports that researchers at the University of California — San Francisco found study participants who drank pop daily had shorter telomeres — the protective units of DNA that cap the ends of chromosomes in cells — in white blood cells. Short telomeres have been associated with chronic aging diseases such as heart disease, diabetes and some forms of cancer. The researchers calculated daily consumption of a 20-ounce pop is associated with 4.6 years of additional biological aging. The effect on telomere length is comparable to that of smoking, they said. "This finding held regardless of age, race, income and education level," researcher Elissa Epel said in a press release.

sagecreek writes "You can judge this book, at least in part, by the lengthy tagline on its cover: 'Learn to make practical, unique, real-world sites that span a variety of industries and technologies with the world's most popular mobile development library.' jQuery might not be your favorite framework on the long, long list of JavaScript possibilities. But Shane Gliser unabashedly describes himself as a jQuery 'fanboy...if it's officially jQuery, I love it.' Gliser is an experienced mobile developer and blogger who operates Roughly Brilliant Digital Studios. He also has some background in mobile UX (user experience), and both qualities show in this smoothly written, well-illustrated, 234-page how-to book that focuses on jQuery Mobile, a 'touch-optimized' web framework for smartphones and tablets."

Michael J. Ross writes "Of all Web technologies, JavaScript may have the most checkered past — first heralded as a powerful object-oriented language for jazzing up Web pages, but later condemned as a source of spammy pop-up windows and horrid animations polluting websites everywhere. Yet during the past several years, Web designers and developers are increasingly using JavaScript unobtrusively, for client-site interactivity — as a supplement to server-side functionality, not a replacement, and built upon standards-compliant (X)HTML and CSS. As a result, the once-derided language is now enjoying a true resurgence in interest and use. This has been bolstered by the proliferation of JavaScript libraries, of which jQuery is clearly the front runner. Web programmers seeking to get up to speed on this exciting resource can turn to Learning jQuery 1.3: Better Interaction Design and Web Development with Simple JavaScript Techniques."

Michael J. Ross writes "Two decades ago, Web usage was limited to a single individual (Sir Tim Berners-Lee) using the only browser in existence (WorldWideWeb) running on a single platform (a NeXT Computer). Nowadays, billions of people access the Web daily, with the ability to choose from over a dozen browsers running on desktop computers, laptops, and a variety of mobile devices, such as cell phones. The number of possible combinations is growing rapidly, and makes it increasingly difficult for Web designers and developers to craft their sites so as to be universally accessible. This is particularly true when accounting for Web users with physical and cognitive disabilities — especially if they do not have access to assistive technologies. The challenges and solutions for anyone creating an accessible website are addressed in Universal Design for Web Applications, authored by Wendy Chisholm and Matt May."

The hype leading up to Spore was excessive. But then, so is the scope of the game; following the growth of a species from the cellular level to galactic domination was an ambitious goal, to say the least. Bringing evolution into the realm of entertainment was something Will Wright hoped and gambled he could do after the success of the Sim franchise. But rather than evolution, Spore became more about creation — creation that allows a single-player game to include the community, as well. It ties the various parts of the game together to make Spore very entertaining as a whole. Read on for my thoughts.

Michael J. Ross writes "When veteran PHP developers have specific and nontrivial functionality that they want to implement in their code, they can do so from scratch, but this can be time-consuming or essentially reinventing the wheel. They can adopt completed code posted in an online discussion forum, but such code tends to be buggy. They can use an open source library or other packaged code, but this approach can oftentimes prove to be overkill. Consequently, many developers prefer focused solutions found in PHP cookbooks, such as The PHP Anthology: 101 Essential Tips, Tricks & Hacks." Read on for the rest of Michael's review.

The anecdotal evidence that's been going around, now that the Wii is an established fixture in American living rooms, is that Nintendo's new console still has room for improvement. We all had fun over the holidays, sharing Wii Sports with our relatives and watching our aunts laugh themselves stupid. Now, though, it's a new year and it's time for the Wii to step up as a gaming platform. It needs to be more than a Zelda player, and the console needs to prove that this 'new gen' style of play is sustainable over the long term. The post-launch round of games has started to trickle out, and the results are definitely mixed. Today I have for you impressions of Elebits and WarioWare: Smooth Moves. These are two games that show quite a bit of promise, but only one of which actually delivers. Read on for my views, and a return to a numeric grading scale.

We got lots and lots of questions for Dean Hachamovitch, whose formal title is "general manager Internet Explorer at Microsoft Corp." Picking a mere 10 of those questions was not easy, and I wish Dean could have answered twice as many -- and so does he, but his schedule has been tight this week. Anyway, here are his answers to the Chosen Ten.

We posted Jay Rosen's Call for Questions on September 25. Here are his answers, into which he's obviously put plenty of time and thought. This is a "must read" for anyone interested in the growing "citizen journalism" movement either as a writer/editor or as an audience member -- and please note that Rosen and many others say, over and over, that one of the major shifts in the news media, especially online, is that there is no longer any need to be one or the other instead of both.
