And although pooled sampling does help conserve testing supplies, a robust infrastructure must be in place to organize the gathering of samples and distribution of results, Zehnder added. "The simplest way is if people can swab themselves and then mail it in," thus avoiding a potentially risky trip to a physical testing site, he said. Once the samples can be gathered and processed, there must be a way to use that information to guide a public health response, which would include tracing potential infections and isolating positive cases in the community, he said. … [Read more...] about Wuhan tested millions of people for COVID-19 in just days.

Because Facebook's entire code base is compiled down to a single binary executable, the company's deployment process is quite different from what you'd normally expect in a PHP environment. Rossi told me that the binary, which represents the entire Facebook application, is approximately 1.5GB in size. When Facebook updates its code and generates a new build, the new binary has to be pushed to all of the company's servers. … [Read more...] about Exclusive: a behind-the-scenes look at Facebook release engineering
There aren't many details of the TX5's hybrid powertrain, but here's what we do know: it'll have a small petrol engine (not diesel!) and a small battery. The TX5 will operate on battery power until it runs out, and then the petrol engine will kick in to top up the battery. In January 2018, new regulations will require all taxis and minicabs in London to be capable of zero-emissions driving for at least 30 miles, so it's fairly safe to assume that the TX5's battery will be capable of around 30 miles. … [Read more...] about London’s next-gen TX5 black cab will be a plug-in hybrid
Instead, this is primarily an app for travel exploration and planning. Each destination hub includes an overview/introduction, with airport name, weather, map, and even currency conversion if it's a foreign country. And of course, you get the usual complement of photos, top attractions, hotels, restaurants, nightlife, shopping information and more. The hope is that, if you find a given destination interesting enough, you'll search for a flight and hotel from within the app, powered by travel company Kayak (which also has its own dedicated Windows 8 app). The actual booking process, however—in what is a common trend with this batch of Metro apps—sends you to an Internet Explorer browsing session. … [Read more...] about Hands-on: News, Sports, and Travel go Metro in Windows 8 Release Preview
In some respects, Flame was less discreet than Duqu. For example, Duqu cloaked the true identity of the attackers by using SSH port forwarding to hide the locations of remote servers that hosted malware scripts. Flame, by contrast, ran malicious scripts directly on the servers. "From this point of view, we can state that the Duqu attackers were a lot more careful about hiding their activities compared to the Flame operators," Gostev wrote. … [Read more...] about Iran-targeting Flame malware used huge network to steal blueprints
