  • Amazon DocumentDB Speeds Up With Slow Queries Logging

    Amazon continues to add extra supports to its non-relational database store DocumentDB with the addition of slow queries logging.

    Slow queries logging allows user to monitor their slowest queries in the cluster. This helps to improve overall performance of the cluster and the individual query.

    Once the user has enabled a set profiler for the query the system will monitor operations and if any queries run longer than the customer-defined threshold, set at 100ms by default, the system will log their execution time and send an alert to the CloudWatch Logs.

  • Exposed Sphinx Servers Are No Challenge for Hackers [Ed: That’s the same agency and the same troll site that initially promoted the lies and the FUD about VLC]

    A popular open-source text search server, Sphinx offers impressive performance for indexing and searching data in databases or just in files. It is cross-platform, available for Linux, Windows, macOS, Solaris, FreeBSD, and a few other operating systems.

    [...]

    CERT-Bund posted the warning on Twitter today alerting network operators and providers about the risk of running Sphinx servers with a default configuration that are open on the web.

    The organization highlights that Sphinx lacks any authentication mechanisms. Exposing it on the web gives an attacker the possibility "to read, modify or delete any data stored in the Sphinx database."

  • Ransomware Hits Texas Local Governments [iophk: Windows TCO]

    The attack was observed on the morning of August 16 and appears to have been launched by a single threat actor, the DIR announcement reads.

    The State Operations Center (SOC) was activated soon after the attack reports started to come in, and DIR says that all of the entities that were actually or potentially affected appear to have been identified and notified.

    A total of twenty-three entities have been confirmed as impacted so far, and the responders are working on bringing the affected systems back online.

  • Webmin Backdoored for Over a Year

    The security hole impacts Webmin 1.882 through 1.921, but most versions are not vulnerable in their default configuration as the affected feature is not enabled by default. Version 1.890 is affected in the default configuration. The issue has been addressed with the release of Webmin 1.930 and Usermin version 1.780.

  • The YubiKey 5Ci is the 'first' iOS-compatible security key

    Like other YubiKey options in the 5 series, the YubiKey 5Ci supports multiple authentication protocols, including IDO2/WebAuthn, FIDO U2F, OTP (one-time-password), PIV (Smart Card), and OpenPGP.

Debian

The Netrunner Team is happy to announce the immediate availability of Netrunner 19.08 Indigo – 64bit ISO.

This time Netrunner 19.08 ships with a brand new Look and Feel called Indigo which features the identically named color as main attraction.

Open source hardware and 3D printers go together like, well, open source hardware and 3D printers. Not only are 3D printers used to create all sorts of open source hardware—there are also a huge number of 3D printers that have been certified as open source by the Open Source Hardware Association. That fact means that they are freely available to improve and build upon.

There are plenty of open source 3D printers out there, with more being certified on a regular basis. Here’s a look at some of the latest.

Elementary OS is the latest group to ditch Medium for their own blog

Filed under
OS

Elementary OS – a Linux distribution (distro) built on top of the large, company-backed giant Ubuntu – is a mom-and-pop store by comparison.

But it's also one that's managed to capture the attention of even some seasoned Linux users thanks to its focus on user interface (UI) and even user experience (UX) – something often lacking from the more spartan distros.

With their focus on icon and UI themes sometimes suspiciously reminiscent of Apple's interfaces – the Elementary OS team have also earned themselves something of a label of “hipsters” in the community.

Five reasons Chromebooks are better than Windows laptops

Filed under
OS
Google

Today, Windows users hold off for as long as possible before "updating" their PCs. Chrome OS users, on the other hand, have their systems updated every six weeks without a hitch. And, I might add, these updates take a minute or two instead of an hour or two.

Chrome OS is also more secure than Windows. WIndows security violations pop up every blessed month. Sure, Chrome OS has had security holes, but I can't think of one that's been significantly exploited.

Want a nightmare? Try migrating from an old Windows PC to a new one. Even if you're jumping from Windows 10 to Windows 10, there are no easy ways to do it. If you have a Microsoft account, rather than a local account, you must manually move your local files from third-party programs such as Photoshop

On Chrome OS, you log in to your new Chromebook and -- ta-da! -- you're back in business. No fuss, no muss.

  • Sajeer Ahamed: Review | GSoC 2019

    I've been working on GStreamer based project of Gnome Foundation. GStreamer is a pipeline-based multimedia framework that links together a wide variety of media processing systems to complete complex workflows. The framework is based on plugins that will provide various codec and other functionality. The plugins can be linked and arranged in a pipeline. And most of the plugins are written in C. Now the developers are in an attempt to convert them to Rust which is more robust and easily maintainable. My task is to be a part of this conversion and to help fix issues related to this.

  • Third month progress

    I am here presenting you with my final month GSoC project report. I will be providing the links to my work at the end of the section.

    Final month of the work period was much more hectic and tiring than the first couple of months. I had been busy more than I had anticipated. Nonetheless, I had to write code which I enjoyed writing : ) . In the first half of this work period, I was focused on completing the left-over QDBus communication from the phase 2, which I did successfully. But as when I thought my task was all over, I was faced with some regression in the code, which I utilised my rest half a month to fix it.

    [...]

    As I had said above in the intro, I was faced with some real difficulty during the second half of the work period. As soon as I finished up QDBus thing, a regression was caused (Which I should have noticed before, my bad), helper was no longer started by the main application. I spent rest of the days brain-storming the issue but due to shortage of time, could not fix it. I plan to try fixing it in the next few days before GSoC ends(26th August), if I successfully do that, I will update the status here as well .
