The $5 Onion Omega2 Gives Raspberry Pi a Run For Its Money

Slashdot - Thu, 18/08/2016 - 8:55pm
An anonymous reader writes from a report via The Daily Dot: Onion's Omega2 computer may give the Raspberry Pi a run for its money if the success of the Kickstarter campaign is any indication. The Daily Dot reports: "With an initial goal of just $15,000, over 11,560 backers have pledged the company $446,792 in hopes of getting their hands on this little wonder board. So why are thousands of people losing their minds? Simple; the Omega2 packs a ton of power into a $5 package. Billed as the world's smallest Linux server, complete with built-in Wi-Fi, the Omega2 is perfect for building simple computers or the web connected project of your dreams. The tiny machine is roughly the size of a cherry, before expansions, and runs a full Linux operating system. For $5 you get a 580MHz CPU, 64MB memory, 16MB storage, built-in Wi-Fi and a USB 2.0 port. A $9 model is also available with 128MB of memory, 32MB of storage, and a MircoSD slot. The similarly priced Raspberry Pi Zero comes with a 1GHz Arm processor, 512MB of memory, a MicroSD slot, no onboard storage, and no built-in Wi-Fi. Omega2 supports the Ruby, C++, Python, PHP, Perl, JavaScript (Node.js), and Bash programming languages, so no matter your background in coding you should be able to figure something out." You can also add Bluetooth, GPS, and 2G/3G support via add-ons or expansions. It looks promising, though it is a Kickstarter campaign and the product may not come into fruition.

Gawker.com To End Operations Next Week

Slashdot - Thu, 18/08/2016 - 8:15pm
After nearly 14 years of operations, Gawker.com will be shutting down next week, the company's outgoing CEO Nick Denton told the staff Thursday. The decision comes days after Univision said it would buy Gawker Media properties -- Gizmodo, Jezebel, Kotaku etc (but not Gawker.com) -- for a sum of $135 million. The publication is currently in the middle of multiple lawsuits, with billionaire Peter Thiel revealing his clandestine legal campaign against the company. In a blog post, Gawker made the announcement. From the story:Nick Denton, the company's outgoing CEO, informed current staffers of the site's fate on Thursday afternoon, just hours before a bankruptcy court in Manhattan will decide whether to approve Univision's bid for Gawker Media's other assets. Staffers will soon be assigned to other editorial roles, either at one of the other six sites or elsewhere within Univision. Near-term plans for Gawker.com's coverage, as well as the site's archives, have not yet been finalized.

Millions Of Steam Game Keys Stolen After Hacker Breaches Gaming Site

Slashdot - Thu, 18/08/2016 - 7:35pm
An anonymous reader writes:A little over nine million keys used to redeem and activate games on the Steam platform were stolen by a hacker who breached a gaming news site last month. The site, DLH.net, provides news, reviews, cheat codes, and forums, was breached on July 31 by an unnamed hacker, whose name isn't known but was also responsible for the Dota 2 forum breach. The site also allows users to share redeemable game keys through its forums, which along with the main site has around 3.3 million unique registered users, according to breach notification site LeakedSource.com, which obtained a copy of the database. A known vulnerability found in older vBulletin forum software, which powers the site's community, allowed the hacker to access the databases. The data stolen from the forum includes full names, usernames, scrambled passwords, email addresses, dates of birth, join dates, avatars, Steam usernames, and user activity data. Facebook access tokens were stolen for those who signed in with their social account.

How norovirus gets inside cells: New clues

Science Daily - Thu, 18/08/2016 - 7:00pm
Researchers have identified the protein that norovirus uses to invade cells. Norovirus is the most common viral cause of diarrhea worldwide, but scientists still know little about how it infects people and causes disease because the virus grows poorly in the lab. The discovery, in mice, provides new ways to study a virus notoriously hard to work with and may lead to treatments or a vaccine.

New flu strains and old antibodies: How sinful is 'original antigenic sin'?

Science Daily - Thu, 18/08/2016 - 6:59pm
Immune memory ensures a quick, specific response to previously encountered pathogens. However, for rapidly evolving pathogens like influenza virus, there is concern that recalled ('old') antibodies dominate and compromise the response against a changed ('new') infectious strain. A mouse study reports that while influenza exposure history does influence the antibody response to a circulating flu virus, this does not appear to compromise the defense against the new strain.
