California Governor Says 'We Need More Googles' As Company Offers Free Wi-Fi and Chromebooks To Students

Slashdot - Enj, 02/04/2020 - 5:30pd
An anonymous reader quotes a report from CNBC: Google will offer 100,000 free Wi-Fi hotspots and will donate 4,000 Chromebooks to students across the state of California, governor Gavin Newsom said during a news conference Wednesday. The internet access points are supposed to help improve broadband internet in rural households across the state where internet access is either limited or very slow. Students will get access to the free Wi-Fi for a minimum of three months.There are still many parts of the state that do not have access to high-speed internet, however. "This was a substantial enhancement that came just at the right time," Newsom said. "We need more Googles," he added. The latest move comes as Newsom announced that California schools will remain closed for the remainder of the school year with many classes switching to online learning.

New X-Ray Technique Images Soft-Tissue Tumors Clearer Than MRI

Slashdot - Enj, 02/04/2020 - 4:10pd
Researchers at Tohoku University have developed a new method of adapting X-ray to image soft tissue, "so that its higher resolution can reveal tumors or other problems earlier than other techniques," reports New Atlas. From the report: Elastography is a field of medical imaging that focuses on the stiffness or softness of tissues. Shear waves are sent through the body, and then an imaging technology like ultrasound or MRI is used to watch how they spread. The waves move through stiff tissue faster than they do through soft tissue, and since tumors, lesions and hardened arteries are all stiffer than surrounding tissue, the technique can highlight these signs of disease. X-rays usually work on a different mechanism, but recent research has suggested that they could be applied to elastography too. And if they were, the resulting images would be much higher resolution, able to spot things on the scale of microns instead of millimeters. And now, X-ray elastography has moved from principle to practice. The Tohoku team has taken the first images using the technique, and shown that it is able to identify the stiffness of different materials. The researchers imaged a polyacrylamide gel, with some samples containing harder particles of zirconium dioxide. Vibrations were then sent through these samples while X-ray images were taken. And sure enough, the X-ray elastography method was able to spot these tiny intruders. After showing that the concept does work, the researchers say that the next steps are to create 3D images, and eventually develop x-ray elastography equipment for medical diagnoses. The research was published in the journal Applied Physics Express.

Early Meme Site YTMND Has Been Resurrected With the Help of Fans

Slashdot - Enj, 02/04/2020 - 3:30pd
The popular early internet meme machine YTMND.com is back online after shutting down last May due to declining ad revenue and the site creator's ill health. Motherboard reports: Launched in 2001, YTMND was one of the early internet's first sources of viral content. Users could attach a gif, often animated but not always, to a piece of looping sound. Users could vote on these animations, share, or remix them. Its death was sad, a piece of early internet, gone forever. But over the last year, [the site's creator Max Goldberg] said fans helped him test the new site, find bugs, and pushed him for regular updates. Goldberg said he rebuilt the site from the ground up, which is why it took the better part of a year. One of the biggest challenges was converting everything away from Flash, which Adobe is finally retiring this year. "That means YTMNDs play more reliably (and work on mobile phones!) and will also be future-compatible," Goldberg said. "The new player was written in a way that makes archiving a YTMND significantly easier, which opens up a lot of possibilities. I've also removed all social media and advertising from the site." He also replaced all the hardware that was running the site.

Teardown of Huawei Flagship Phone Finds US Parts Despite Blacklisting

Slashdot - Enj, 02/04/2020 - 2:10pd
An anonymous reader quotes a report from Ars Technica: Huawei is still using components made by U.S. companies in its newest flagship smartphone, a Financial Times teardown has found, despite the U.S. all but blacklisting the Chinese telecoms equipment manufacturer. The teardown was done by XYZone, a Shenzhen-based company that disassembles smartphones and identifies the suppliers of their components. The biggest surprise was that some parts from U.S. companies were still ending up in the newest Huawei smartphone, despite the U.S. all but banning its companies from selling to the Chinese tech company. The P40's radio-frequency front-end modules were, according to XYZone's teardown analysis, produced by Qualcomm, Skyworks, and Qorvo, three U.S. chip companies. RF front-end modules are critical parts of the phone that are attached to the antennas and required to make calls and connect to the Internet. The Qualcomm component is covered by a license from the U.S. Commerce Department, according to a person familiar with the company. [...] The "Entity List" designation means that U.S. companies have to apply for a license to export any U.S.-origin technologies to Huawei. The U.S. government has granted a "temporary general license" to its companies, allowing them to sell to Huawei to service existing products -- helping clients such as telecoms carriers that may need to replace parts of their wireless equipment. But the general license does not cover sales for the purpose of making new products, such as the P40 smartphone. For that, companies must seek individual licenses, and the Department of Commerce has not said which ones it has granted them to. A spokesperson for Huawei said the company has "always complied with any export control regulations of various countries, including the United States" and that "all the product materials are obtained legally from our global partners, and we insist on working with our partners to provide consumers with high quality products and services." Also missing from the P40 are parts from U.S. chipmaker Micron. "Micron made the storage devices called NAND flash memory chips for some batches of last year's P30 smartphone, and South Korea's Samsung made the same chips for other batches," reports Ars. "The FT's copy of this year's P40 Pro appears to have only Samsung NAND flash memory chips."

Opera To Support Sites Using the<nobr> <wbr></nobr>.Crypto Top-Level Domain

Slashdot - Enj, 02/04/2020 - 1:30pd
Opera has updated its lightweight browser for Android so that it can access unofficial .crypto domains, primarily to exchange cryptocurrency. The Register reports: Support for .crypto in Opera will "bring the blockchain-browsing experience to a new level," the Norwegian software maker gushed on Monday. Crucially, dot-crypto simply doesn't exist in the global domain name system, and is not recognized by DNS overseer ICANN nor the world's DNS resolvers. It is a renegade generic top-level domain masterminded by Unstoppable Domains. By using a domain, such as sendmemoneee.crypto, linked to a blockchain, sending and receiving cryptocurrency becomes much easier as you only need to recall a domain name (ending in .crypto) rather than a long wallet ID. In its effort to carve a niche in the browser market, Opera has been embracing cryptocurrency. Back in December 2018, it added a built-in crypto wallet to its Android browser and then later to its desktop browser. It then extended that to allow for purchases with cryptocurrency. As such, adding a simple addressing system makes sense. It is also a vote of confidence in Unstoppable Domains and Ethereum's alternate root approach.

Hospitals Tell Doctors They'll Be Fired If They Speak Out About Lack of Gear

Slashdot - Enj, 02/04/2020 - 12:50pd
schwit1 shares a report from Bloomberg, commenting: "And the claim that this is about protecting 'patient privacy' is b***shit." From the report: Ming Lin, an emergency room physician in Washington state, said he was told Friday he was out of a job because he'd given an interview to a newspaper about a Facebook post detailing what he believed to be inadequate protective equipment and testing. In Chicago, a nurse was fired after emailing colleagues that she wanted to wear a more protective mask while on duty. In New York, the NYU Langone Health system has warned employees they could be terminated if they talk to the media without authorization." Doctors are a famously independent profession, where individual medical judgment on what's best for the patient is prized over administrative dictates. That's reared its head during the Covid-19 outbreak, with many physicians, nurses and other health-care workers taking to social media to express deep concerns about the lack of protective gear or much-needed patient-care equipment like respirators. Some posts have gone viral and are being shared hundreds of thousands of times, often tagged with #GetMePPE. Privacy laws prohibit disclosing specific patient information, but they don't bar discussing general working conditions. The report notes that not all hospitals are blocking staff from talking to the press. "New York's Mount Sinai has been scheduling media interviews for nurses, physicians and trainees to help the public understand the severity of the crisis," reports Bloomberg. "The University of California San Francisco Medical Center has gotten hundreds of such calls and encouraged workers to talk to reporters."

Microsoft President Calls Washington State's New Facial Recognition Law 'a Significant Breakthrough'

Slashdot - Enj, 02/04/2020 - 12:10pd
Microsoft President Brad Smith took a break from responding to the COVID-19 outbreak this week to praise Washington state's landmark facial recognition regulations. Washington Gov. Jay Inslee signed a bill Tuesday that establishes rules specifically governing facial recognition software. From a report: Smith called the law an "early and important model" and "a significant breakthrough" in a blog post published Tuesday. Some cities have enacted their own facial recognition rules, but Washington is the first to establish statewide regulations. "This balanced approach ensures that facial recognition can be used as a tool to protect the public, but only in ways that respect fundamental rights and serve the public interest," Smith said. The new law requires public agencies to regularly report on their use of facial recognition technology and test the software for fairness and accuracy. Law enforcement agencies must obtain a warrant before using facial recognition software in investigations unless there is an emergency. The bill also establishes a task force to study the use of facial recognition by government agencies. Under the bill, public entities using facial recognition software to make decisions that produce "legal effects" must ensure a human reviews the results. That category includes decisions that could affect a person's job, financial services, housing, insurance, and education.

Ben Hutchings: Debian LTS work, March 2020

Bits from Debian - Mër, 01/04/2020 - 11:34md

I was assigned 20 hours of work by Freexian's Debian LTS initiative, and carried over 0.75 hours from February. I only worked 12.25 hours this month, so I will carry over 8.5 hours to April.

I issued DLA 2114-1 for the update to linux-4.9.

I continued preparing and testing the next update to Linux 3.16. This includes a number of filesystem fixes that require running the "xfstests" test suite.

I also replied to questions from LTS contributors and users, sent to me personally or on the public mailing list.

T-Mobile Officially Completes Merger With Sprint, CEO John Legere Steps Down

Slashdot - Mër, 01/04/2020 - 11:30md
An anonymous reader quotes a report from TechCrunch: After months of regulatory maneuvering, T-Mobile and Sprint officially completed their $26 billion merger today. The new combined parent company is called T-Mobile and will now trade on the Nasdaq under the ticker symbol TMUS with Sprint no longer trading on the NYSE. For consumers, it will seemingly take a little time before the effects of the transition are meaningfully felt. T-Mobile did not comment on the future of the Sprint brand in today's announcement, but they have previously promised that subscribers will have access to "the same or better rate plans" for three years as part of the deal. Alongside news of the merger being finalized, T-Mobile shared that its CEO transition is taking place early. John Legere was supposed to stay on until the end of April, but Mike Sievert has been appointed CEO a month early, effective immediately. Sievert was previously T-Mobile's COO. Legere is still on the company's board of directors, but he'll be stepping down at the end of his term through June.

Doctors Turn To Twitter and TikTok To Share Coronavirus News

Slashdot - Mër, 01/04/2020 - 10:10md
In a sign of the times, doctors are effectively waging a two-pronged fight against coronavirus: one part takes place in overcrowded hospitals and the other takes place on noisy social media platforms as they work to combat what the World Health Organization has declared an infodemic with accurate, authoritative voices. From a report: All of that means doctors, some of whom were once reluctant to embrace social media, are wading deeper into platforms that are rife with fake news, unproven medical advice and mass panic. "Social media is the disease and the cure. It is responsible for the dissemination of misinformation as much as it needs to be a tool for repairing that," said Rick Pescatore, an emergency room physician and public health expert in the Philadelphia area, who is active on Twitter and Facebook and has treated Covid-19 patients. "It's incumbent upon physicians, who want to get real information out there, to meet these patients where they are -- and that's social media." Perhaps nowhere is this shift more striking than on TikTok, a short-form video platform beloved by teens that is best known for lip syncing, dance routines and comedy skits. In one TikTok video viewed more than 416,000 times, a registered nurse named Miki Rai does a choreographed dance involving a lot of hand motions as facts about Covid-19 flash on the screen, such as how long the virus stays on different surfaces. In another TikTok video, set to soothing elevator music, Dr. Rose Marie Leslie demonstrates proper handwashing: Wet hands. Lather up. Start washing for 20 seconds. Scrub under your nails and between fingers. Rinse. Leslie, a resident physician specializing in family medicine at the University of Minnesota Medical School, created a TikTok account about a year ago, with the aim of reaching a younger demographic with health education information. Soon after coronavirus cases started emerging, she began creating TikToks about the issue. Now, she works to debunk myths about the virus for her more than 500,000 followers.

Cash App Scammers Are Using Coronavirus To Exploit People

Slashdot - Mër, 01/04/2020 - 9:30md
An anonymous reader shares a report: Reyna is a teenager in Florida whose family is strapped for cash amid the economic slowdown caused by the coronavirus. When the uber-popular beauty influencer Jeffree Star tweeted that he'd be giving out $30,000 via payment service Cash App to a random person who retweeted him, she did just that. Star's offer seems to have been legitimate -- and drummed up a lot of attention for the influencer. A woman actually won the $30,000, and Reyna missed out. But then another Twitter user messaged Reyna asking whether she wanted to get $250, she told Quartz. "My goal is to help those in need or need emergency cash," the person said. The catch was that she'd have to pay $25 first. "Your deposit along with our other earnings allows us to immediately send you your payment," the person said. Reyna sent the cash, and that's when the Twitter user blocked her, and her money was gone, she said. What happened to Reyna is a popular Cash App scam called "cash-flipping," according to Satnam Narang, researcher at the cybersecurity company Tenable. Con artists are taking advantage of the coronavirus by pretending they are helping the needy. While Reyna simply got a direct message to lure her in after she expressed interest in a legitimate giveaway, other scammers have been promoting fake giveaways in public tweets adding "#coronavirus" in order to reach more people. Sometimes they will request money through Cash App pretending that it's a verification mechanism. "They'll say, you won this giveaway, send us $10 to verify to win 500 bucks," Narang said. The scammers say they have a special way of modifying the transactions through payment applications like Cash App, Paypal, Zelle, Venmo, or Apple Pay, Narang wrote in a blog post explaining the scams. "All they ask for is that the recipient share the initial cut with them for providing them this so-called service." This, of course, is all made up.

Ted Chiang Explains the Disaster Novel We All Suddenly Live In

Slashdot - Mër, 01/04/2020 - 8:50md
The esteemed science fiction author, best known for movie "Arrival" that is based on his novel, on how we may never go "back to normal" -- and why that might be a good thing. From an interview on Electric Literature: EL: Do you see aspects of science fiction (your own work or others) in the coronavirus pandemic? In how it is being handled, or how it has spread? TC: While there has been plenty of fiction written about pandemics, I think the biggest difference between those scenarios and our reality is how poorly our government has handled it. If your goal is to dramatize the threat posed by an unknown virus, there's no advantage in depicting the officials responding as incompetent, because that minimizes the threat; it leads the reader to conclude that the virus wouldn't be dangerous if competent people were on the job. A pandemic story like that would be similar to what's known as an "idiot plot," a plot that would be resolved very quickly if your protagonist weren't an idiot. What we're living through is only partly a disaster novel; it's also -- and perhaps mostly -- a grotesque political satire. EL: This pandemic isn't science fiction, but it does feel like a dystopia. How can we understand the coronavirus as a cautionary tale? How can we combat our own personal inclinations toward the good/evil narrative, and the subsequent expectation that everything will return to normal? TC: We need to be specific about what we mean when we talk about things returning to normal. We all want not to be quarantined, to be able to go to work and socialize and travel. But we don't want everything to go back to business as usual, because business as usual is what led us to this crisis. COVID-19 has demonstrated how much we need federally mandated paid sick leave and universal health care, so we don't want to return to a status quo that lacks those things. The current administration's response ought to serve as a cautionary tale about the dangers of electing demagogues instead of real leaders, although there's no guarantee that voters will heed it. We're at a point where things could go in some very different ways, depending on what we learn from this experience.

Joachim Breitner: 30 years of Haskell

Bits from Debian - Mër, 01/04/2020 - 8:16md

Vitaly Bragilevsky, in a mail to the GHC Steering Committee, reminded me that the first version of the Haskell programming language was released exactly 30 years ago. On April 1st. So that raises the question: Was Haskell just an April fool's joke that was never retracted?

The cover of the 1.0 Haskell report

My own first exposure to Haskell was in April 2005; the oldest piece of Haskell I could find on my machine is this part of a university assignment from April:

> pascal 1 = [1] > pascal (n+1) = zipWith (+) (x ++ [0]) (0 : x) where x = pascal n

This means that I now have witnessed half of Haskell's existence. I have never regretted getting into Haskell, and every time I come back from having worked in other languages (which all have their merits too), I greatly enjoy the beauty and elegance of expressing my ideas in a lazy and strictly typed language with a concise syntax.

I am looking forward to witnessing (and, to a very small degree, shaping) the next 15 years of Haskell.

Apple's iOS 14 May Turn iCloud Keychain Into a True 1Password and LastPass Competitor

Slashdot - Mër, 01/04/2020 - 8:10md
Apple's native iOS password manager may be getting an overhaul later this year with the presumed release of iOS 14 that will make it more competitive with third-party options like 1Password and LastPass, reports 9to5Mac. From a report: Right now, iCloud Keychain can store your passwords and help autofill them on the iPhone, where copying and pasting long strings of letters and numbers or manually doing so has been a headache since the advent of the mobile touchscreen. But it doesn't have reminders for changing those passwords like competitors do, and it doesn't support two-factor authentication (2FA) options. That means users are still stuck using potentially insecure methods like SMS or email in the event that they do have 2FA set up.

Sylvain Beucler: Debian LTS and ELTS - March 2020

Bits from Debian - Mër, 01/04/2020 - 4:26md

Here is my transparent report for my work on the Debian Long Term Support (LTS) and Debian Extended Long Term Support (ELTS), which extend the security support for past Debian releases, as a paid contributor.

In March, the monthly sponsored hours were split evenly among contributors depending on their max availability - I was assigned 30h for LTS (out of 30 max; all done) and 20h for ELTS (out of 20 max; I did 0).

Most contributors claimed vulnerabilities by performing early CVE monitoring/triaging on their own, making me question the relevance of the Front-Desk role. It could be due to a transient combination of higher hours volume and lower open vulnerabilities.

Working as a collective of hourly paid freelancers makes it more likely to work in silos, resulting in little interaction when raising workflow topics on the mailing list. Maybe we're reaching a point where regular team meetings will be benefical.

As previously mentioned, I structure my work keeping the global Debian security in mind. It can be stressful though, and I believe current communication practices may deter such initiatives.

ELTS - Wheezy

  • No work. ELTS has few sponsors right now and few vulnerabilities to fix, hence why I could not work on it this month. I gave back my hours at the end of the month.

Joey Hess: DIN distractions

Bits from Debian - Mër, 01/04/2020 - 4:12md

My offgrid house has an industrial automation panel.

I started building this in February, before covid-19 was impacting us here, when lots of mail orders were no big problem, and getting an unusual 3D-printed DIN rail bracket for a SSD was just a couple clicks.

I finished a month later, deep into social isolation and quarentine, scrounging around the house for scrap wire, scavenging screws from unused stuff and cutting them to size, and hoping I would not end up in a "need just one more part that I can't get" situation.

It got rather elaborate, and working on it was often a welcome distraction from the news when I couldn't concentrate on my usual work. I'm posting this now because people sometimes tell me they like hearing about my offfgrid stuff, and perhaps you could use a distraction too.

The panel has my house's computer on it, as well as both AC and DC power distribution, breakers, and switching. Since the house is offgrid, the panel is designed to let every non-essential power drain be turned off, from my offgrid fridge to the 20 terabytes of offline storage to the inverter and satellite dish, the spring pump for my gravity flow water system, and even the power outlet by the kitchen sink.

Saving power is part of why I'm using old-school relays and stuff and not IOT devices, the other reason is of course: IOT devices are horrible dystopian e-waste. I'm taking the utopian Star Trek approach, where I can command "full power to the vacuum cleaner!"

At the core of the panel, next to the cubietruck arm board, is a custom IO daughterboard. Designed and built by hand to fit into a DIN mount case, it uses every GPIO pin on the cubietruck's main GPIO header. Making this board took 40+ hours, and was about half the project. It got pretty tight in there.

This was my first foray into DIN rail mount, and it really is industrial lego -- a whole universe of parts that all fit together and are immensely flexible. Often priced more than seems reasonable for a little bit of plastic and metal, until you look at the spec sheets and the ratings. (Total cost for my panel was $400.) It's odd that it's not more used outside its niche -- I came of age in the Bay Area, surrounded by rack mount equipment, but no DIN mount equipment. Hacking the hardware in a rack is unusual, but DIN invites hacking.

Admittedly, this is a second system kind of project, replacing some unsightly shelves full of gear and wires everywhere with something kind of overdone. But should be worth it in the long run as new gear gets clipped into place and it evolves for changing needs.

Also, wire gutters, where have you been all my life?

Finally, if you'd like to know what everything on the DIN rail is, from left to right: Ground block, 24v DC disconnect, fridge GFI, spare GFI, USB hub switch, computer switch, +24v block, -24v block, IO daughterboard, 1tb SSD, arm board, modem, 3 USB hubs, 5 relays, AC hot block, AC neutral block, DC-DC power converters, humidity sensor.
