  • The developer of Helium Rain gave an update on their sales, low overall sales but a high Linux percentage
    Helium Rain [Steam, Official Site], the gorgeous space sim from Deimos Games is really quite good so it's a shame they've seen such low overall sales. In total, they've had around 14,000€ (~$17,000) in sales which is not a lot for a game at all. The good news, is that out of the two thousand copies they say they've sold, a huge 14% of them have come from Linux. It's worth noting, that number has actually gone up since we last spoke to them, where they gave us a figure of 11% sales on Linux.

  • IRS Website Crash Reminder of HealthCare.gov Debacle as OMB Pushes Open Source
    OMB is increasingly pushing agencies to adopt open source solutions, and in 2016 launched a pilot project requiring at least 20 percent of custom developed code to be released as open source – partly to strengthen and help maintain it by tapping a community of developers. OMB memo M-16-21 further asks agencies to make any code they develop available throughout the federal government in order to encourage its reuse. “Open source solutions give agencies access to a broad community of developers and the latest advancements in technology, which can help alleviate the issues of stagnated or out-dated systems while increasing flexibility as agency missions evolve over time,” says Henry Sowell, chief information security officer at Hortonworks Federal. “Enterprise open source also allows government agencies to reduce the risk of vendor lock-in and the vulnerabilities of un-supported software,” he adds.
  • Migrations: the sole scalable fix to tech debt.

    Migrations are both essential and frustratingly frequent as your codebase ages and your business grows: most tools and processes only support about one order of magnitude of growth before becoming ineffective, so rapid growth makes them a way of life. This isn't because they're bad processes or poor tools, quite the opposite: the fact that something stops working at significantly increased scale is a sign that it was designed appropriately to the previous constraints rather than being over designed.

  • When you go to a security conference, and its mobile app leaks your data
     

    A mobile application built by a third party for the RSA security conference in San Francisco this week was found to have a few security issues of its own—including hard-coded security keys and passwords that allowed a researcher to extract the conference's attendee list. The conference organizers acknowledged the vulnerability on Twitter, but they say that only the first and last names of 114 attendees were exposed.

  • The Security Risks of Logging in With Facebook
     

    In a yet-to-be peer-reviewed study published on Freedom To Tinker, a site hosted by Princeton's Center for Information Technology Policy, three researchers document how third-party tracking scripts have the capability to scoop up information from Facebook's login API without users knowing. The tracking scripts documented by Steven Englehardt, Gunes Acar, and Arvind Narayanan represent a small slice of the invisible tracking ecosystem that follows users around the web largely without their knowledge.

  • Facebook Login data hijacked by hidden JavaScript trackers
     

    If you login to websites through Facebook, we've got some bad news: hidden trackers can suck up more of your data than you'd intended to give away, potentially opening it up to abuse.
