ZDNet reports that Singapore is fighting the coronavirus with a new smartphone app named "TraceTogether". The app is able to estimate the distance between TraceTogether smartphones as well as the duration of such interactions. The data then is captured, encrypted, and stored locally on the user's phone for 21 days, which spans the incubation period of the virus. When needed in contact tracing, users will have to authorise the uploading of their TraceTogether data to Singapore's Ministry of Health, which then will assess the information and retrieve the mobile numbers of close contacts within that period of time. Developed by Government Technology Agency (GovTech), alongside the health ministry, the app was designed to help speed up the contact tracing process and stem the spread of COVID-19, the government IT office said. GovTech said the current processed depended heavily on the memory of patients, who might not be ale to remember all close contacts or have the contact details and information of these individuals. The mobile app can plug the gaps and more quickly identify potential carriers, who then can monitor their health and take the necessary action sooner... Data logs were stored locally on the mobile phone and contained only cryptographically generated temporary IDs. The data logs would be extracted only when needed by the authorities for contact tracing, it said.

A senior Russian official says an upcoming digital assets bill will ban the issuing and selling of cryptocurrencies. Forbes reports: "We believe there are big risks of legalizing the operations with the cryptocurrencies, from the standpoint of financial stability, money laundering prevention and consumer protection," Russia's central bank head of legal, Alexey Guznov, told Russia news agency Interfax this week in comments translated to English via Google. "We are opposed to the fact that there are institutions that organize the release of cryptocurrency and facilitate its circulation," Guznov said, adding the coming bill "directly formulates a ban on the issue, as well as on the organization of circulation of cryptocurrency, and introduces liability for violation of this ban...." However, Guznov admitted that Russia would not be able to completely ban bitcoin and other cryptocurrencies. "Nobody is going to ban owning cryptocurrencies," Guznov said, adding people will not be punished for owning crypto "if they made their deal in a jurisdiction that does not prohibit that."

America's Food and Drug Administration has approved a coronavirus test from a company called Cepheid. It can deliver its results in about 45 minutes, "much faster than current tests that require a sample to be sent to a centralized lab, where results can take days," reports The Hill: The test has been designed to operate on any of Cepheid's more than 23,000 automated GeneXpert Systems worldwide, of which 5,000 are in the U.S., the company said. The systems are already being used to test for conditions such as HIV and tuberculosis. The systems do not require users to have specialty training to perform testing and are capable of running around the clock. "An accurate test delivered close to the patient can be transformative" and can "help alleviate the pressure" that the COVID-19 outbreak has put on health facilities, David Persing, Cepheid's chief medical and technology officer, said in a statement.

"The dramatic expansion of teleworking by U.S. schools, businesses and government agencies in response to the coronavirus is raising fresh questions about the capacity and security of the tools many Americans use to connect to vital workplace systems and data," reports CNN: As of last week the Air Force's virtual private networking software could only support 72,000 people at once, according to a federal contractor who was also not authorized to speak on the record, and telework briefing materials viewed by CNN. The Air Force employs over 145,000 in-house civilian workers, and over 130,000 full-time contractors. As they increasingly log on from home, Americans are having to meld their personal technology with professional tools at unprecedented scale. For employers, the concern isn't just about capacity, but also about workers introducing new potential vulnerabilities into their routine — whether that's weak passwords on personal computers, poorly secured home WiFi routers, or a family member's device passing along a computer virus. Long-time Slashdot reader Lauren Weinstein also worries about a world where "doctors switch to heavy use of video office visits, and in general more critical information than ever is suddenly being thrust onto the Internet..." For example, the U.S. federal government is suspending key aspects of medical privacy laws to permit use of "telemedicine" via commercial services that have never been certified to be in compliance with the strict security and privacy rules associated with HIPAA (Health Insurance Portability and Accountability Act). The rush to provide more remote access to medical professionals is understandable, but we must also understand the risks of data breaches that once having occurred can never be reversed.

Linus Torvalds himself "changed around the kernel's pipe code to use exclusive waits when reading or writing," reports Phoronix. "While this doesn't mean much for traditional/common piping of data, the GNU Make job-server is a big benefactor as it relies upon a pipe for limiting the parallelism" -- especially on high-core-count CPUs. This drew an interesting follow-up from Slashdot reader rockyb, who was wondering if anyone could verify that GNU Make 4.3 speeds up build times: I updated and released a fork of that called remake which includes hooks to profile a build, and has a complete debugger in it (although most of the time the better tracing that is in there is enough). The most recent version has a feature though that I really like and use a lot which is adding an option to look in parent directories for a Makefile if none is found in the current directory. You can download the source code from either github or sourceforge. Both have a full list of the release notes. Sorry, at the time of this writing no packagers have picked up the newest release. Repology has a list of packages for older versions though.

"Former astronaut Alfred M. Worden, command module pilot on the Apollo 15 lunar landing, passed away March 18, 2020, in Texas," reports NASA.gov. His son-in-law told the New York Times Worden apparently died of a stroke. "Al was an American hero whose achievements in space and on Earth will never be forgotten," tweeted NASA Administrator Jim Bridenstine. Slashdot reader Iwastheone shares NASA's remembrance: As command module pilot, Worden stayed in orbit while commander David Scott and lunar module pilot James B. Irwin explored the Moon's Hadley Rille and Appennine Mountains. Apollo 15's command module, dubbed Endeavour, was the first to have its own module of scientific instruments. During the flight back from the Moon, Worden retrieved film from cameras in the module during a spacewalk. Altogether, Worden logged more than 295 hours in space. "The thing that was most interesting to me was taking photographs of very faint objects with a special camera that I had on board," Worden told Smithsonian Magazine in 2011. "These objects reflect sunlight, but it's very, very weak and you can't see it from [Earth]. There are several places between the Earth and the moon that are stable equilibrium points. And if that's the case, there has to be a dust cloud there. I got pictures of that." Like other command module pilots, Worden stayed as busy as his colleagues on the surface. But he also took some time to enjoy the view. "Every time I came around the moon I went to a window and watched the Earth rise and that was pretty unique." In 1972 Worden appeared twice on Mister Rogers Neighborhood. And Mister Rogers also filmed segments at Cape Canaveral, with Worden demonstrating his space suit and later supplying answers to a list of questions from children while standing in the mission's launch room. "I asked Fred to let me take the list into space," Worden wrote in his autobiography. "I would think about them during the flight, I promised, and then answer when I returned."

I had to run errands into Kingston just now and heard Gov Cuomo's press conference. He is masterful. I feel like there's someone in charge who knows what to do and is doing it. I feel lucky to live in New York State, wish we had something approaching that kind of leadership in Washington.

Now I wish there were a podcast feed for his press conferences so I could listen to them asynchronously. I won't always be able to listen when they're happening. Maybe this is something WNYC or the NY Times could do? Betaworks?

Linus Torvalds tells ZDNet what he's learned about working remotely: Torvalds admits that when he started, "I worried about missing human interaction -- not just talking to people in the office and hallways, but going out to lunch etc. It turns out I never really missed it." Of course, just saying "'don't be social' isn't much of a great tip, is it?" Nor, as many extroverts are now finding out, is working from home necessarily at all comfortable. So, Torvalds suggests that you take "advantage of the 'real' upside of working from home: flexibility... Torvalds says, "if you make your new life a '9-5, but from home' kind of thing, I think you're just going to hate your home, yourself and your life. All the downsides, none of the upsides...." He believes that instead of using "video conferencing instead to recreate exactly what we used to do before, you should" try to really change how you work. Use asynchronous communication models: messaging, email, shared calendars, whatever. Torvalds also recommends carefully tracking the things that you need to do, but argues that if you're spending hours in online meetings from home instead of hours in real-world meetings, "you've just taken the worst part of office life, and brought it home, and made it even worse..." And the article also includes some tips from James Bottomley, an IBM Research Distinguished Engineer and senior Linux kernel developer who works closely with Torvald. For videoconferencing Bottomley uses NextCloud Talk and Zoom, which he calls a "horrible proprietary app" -- but notes that it does have binaries for every Linux distro.

Java "remains the world's most popular programming language," notes ZDNet, reporting on Oracle's release this week of Java Development Kit (JDK) 14, Oracle's "reference implementation of the Java 14 programming language spec." Rolling out in line with Oracle's six-monthly release schedule that began with Java 9 in 2017, JDK 14 includes enhancements that Oracle says will improve developer productivity... According to Georges Saab, Oracle vice president of development for the Java Platform, the faster six-monthly releases are helping developers adopt new features more rapidly due to regular expected changes. Java 9, for example, was released more than three years after Java 8... Saab notes that major improvements in JDK 14 include a Foreign-Memory Access API enhancement (JEP 370), and improvements from Project Amber, another OpenJDK project, including Pattern Matching (JEP 305) and a preview of Records (JEP 359). Oracle JDK 14 will receive at least two quarterly updates in line with Oracle's critical-patch update schedule before Java 15 is released in September 2020. Oracle is providing Java 14 as the Oracle OpenJDK release under an open-source GNU General Public License v2. It's also released under a commercial license using Oracle JDK. Most of the nearly 2,000 fixes in JDK 14 have been made by Oracle employees while 528 came from individual developers and other organizations. Some of the main contributors included Red Hat, SAP, Google, Arm, Intel, and NTT Data.

An anonymous reader quotes the Dev newsletter from Inside.com: The U.S. Supreme Court has postponed hearing oral arguments in the Google vs. Oracle copyright case and all other cases because of the coronavirus. It is the first time the Supreme Court has done so since the Spanish flu epidemic in 1918. ["The Court also shortened its argument calendars in August 1793 and August 1798 in response to yellow fever outbreaks," the announcement points out.] "The court will examine the options for rescheduling those cases in due course in light of the developing circumstances," the announcement added. Justices on the U.S. Supreme Court were scheduled to hear oral arguments in the Google vs. Oracle case on Tuesday, March 24, 2020, before making a decision a few months later.

Rachel Maddow cried at the end of her show last night. I assume for her colleague, a man about my age, who died of CV. But it meant something personal to each of us. I saw it as her crying for the end of America. Reagan was right, government is the problem. But not the way Reagan meant it. I don't know what goes through the minds of the Republicans in Washington, I can't find a bottom to their depravity. It's possible they're masochists. They feel they, and we, deserve to die.

Most times we can convince ourselves that in the immediate future: 1. We will remain alive and well. 2. Our friends and family will too. What's so unsettling about the moment: Now we know that either, we will be sick or die, or some of our friends and family will. I think that's why we are all reaching out to our friends now, and re-establishing the connection, because we want to hold them close so they don't leave us. It's a good thing. In this week's Radio Open Source, at the end, Andrew Sullivan talks about that re AIDS, which he experienced as a gay man in the 80s and 90s. I experienced it as a man with a fatally sick heart in the 00s. After being fixed, I felt like I wanted to die. Weird, right? But real. We call the first feeling "normal." Over time, this will become normal. Then at some point, if we survive, a vaccine or treatment will come about. And we'll go through the unsettled feeling again.
