  • Introducing Chrome Enterprise

    Since we launched Chrome OS in 2009, our goal has been to build the simplest, fastest, and most secure operating system possible. And we’ve been inspired by all the ways we’ve seen businesses embrace Chrome, from Chromebooks in the office, to shared Chrome devices in the field, to signage and kiosks for customer engagement in retail. But with so many different business needs—not to mention so many different devices—companies have also told us they want a single, cost-effective solution that gives them the flexibility and control to keep their employees connected. That’s why today we’re announcing Chrome Enterprise.

  • Google Rolls Out Chrome Enterprise: Chrome OS For Work

Chrome Enterprise costs $50 USD per device per year and includes 24/7 enterprise support.

  • Switch to Gentoo sources

    You've might already read it on the Gentoo news site, the Hardened Linux kernel sources are removed from the tree due to the grsecurity change where the grsecurity Linux kernel patches are no longer provided for free. The decision was made due to supportability and maintainability reasons.

    That doesn't mean that users who want to stick with the grsecurity related hardening features are left alone. Agostino Sarubbo has started providing sys-kernel/grsecurity-sources for the users who want to stick with it, as it is based on minipli's unofficial patchset. I seriously hope that the patchset will continue to be maintained and, who knows, even evolve further.

    Personally though, I'm switching to the Gentoo sources, and stick with SELinux as one of the protection measures. And with that, I might even start using my NVidia graphics card a bit more, as that one hasn't been touched in several years (I have an Optimus-capable setup with both an Intel integrated graphics card and an NVidia one, but all attempts to use nouveau for the one game I like to play - minecraft - didn't work out that well).

A Look at Gentoo based distribution Sabayon

Filed under
Gentoo

Sabayon is a binary based distribution based on the source based distribution Gentoo. In English that means that the developers of Sabayon built a distribution off of Gentoo that no longer has a primary focus of building packages strictly from source, but rather, has it’s own repositories of packages that have been precompiled and are available for download through a new package manager they call Entropy; so even users who are new to GNU/Linux can use Sabayon without the steep learning curve of Gentoo.

Review: Calculate Linux 17.6 KDE

Filed under
Gentoo
Reviews

Calculate Linux is a Gentoo-based distribution. The project's slogan is "Easy Linux from the source," which refers to the fact that Calculate is relatively easy to use but still benefits from Gentoo's powerful and flexible source-based Portage package manager.

Calculate recently celebrated its tenth birthday and released Calculate Linux 17.6. The distro comes in four flavours; apart from a desktop and server edition there's Calculate Scratch ("for those who want to build a customized system that works for them") and Calculate Media Center ("for your home multimedia center"). Each version is available for the x86_64 and i686 architectures and uses SysV init rather than systemd. The desktop edition has ISOs for the KDE, Cinnamon, MATE and Xfce desktop environments - GNOME is presumably not available because of its dependency on systemd. I opted for the 64-bit KDE version, which is just over 2GB in size.

Alpine Linux is an OS at a new peak of binary packaging

Filed under
Gentoo

The Alpine Linux distribution is described as ‘minimal’ and best suited for ‘power users’.

Originally created by Gentoo, the project is now wholly independent and, as such, it is self-hosting.

Gentoo Linux is another distribution… but built the Portage package management system. This project is essentially a security-oriented lightweight Linux distribution based on musl libc and Busybox.

  • Logstash 6.2.0 Release Improves Open Source Data Processing Pipeline
    The "L" in the ELK stack gets updated with new features including advanced security capabilities. Many modern enterprises have adopted the ELK (Elasticsearch, Logstash, Kibana) stack to collect, process, search and visualize data. At the core of the ELK stack is the open-source Logstash project which defines itself as a server-side data processing pipeline - basically it helps to collect logs and then send them to a users' "stash" for searching, which in many cases is Elasticsearch.

  • The 4 Major Tenets of Kubernetes Security
    We look at security from the perspective of containers, Kubernetes deployment itself and network security. Such a holistic approach is needed to ensure that containers are deployed securely and that the attack surface is minimized. The best practices that arise from each of the above tenets apply to any Kubernetes deployment, whether you’re self-hosting a cluster or employing a managed service. We should note that there are related security controls outside of Kubernetes, such as the Secure Software Development Life Cycle (S-SDLC) or security monitoring, that can help reduce the likelihood of attacks and increase the defense posture. We strongly urge you to consider security across the entire application lifecycle rather than take a narrow focus on the deployment of containers with Kubernetes. However, for the sake of brevity, in this series, we will only cover security controls within the immediate Kubernetes environment.
  • GPUs on Google’s Kubernetes Engine are now available in open beta
    The Google Kubernetes Engine (previously known as the Google Container Engine and GKE) now allows all developers to attach Nvidia GPUs to their containers. GPUs on GKE (an acronym Google used to be quite fond of, but seems to be deemphasizing now) have been available in closed alpha for more than half a year. Now, however, this service is in beta and open to all developers who want to run machine learning applications or other workloads that could benefit from a GPU. As Google notes, the service offers access to both the Tesla P100 and K80 GPUs that are currently available on the Google Cloud Platform.

Chrome and Firefox

  • The False Teeth of Chrome's Ad Filter.
    Today Google launched a new version of its Chrome browser with what they call an "ad filter"—which means that it sometimes blocks ads but is not an "ad blocker." EFF welcomes the elimination of the worst ad formats. But Google's approach here is a band-aid response to the crisis of trust in advertising that leaves massive user privacy issues unaddressed. Last year, a new industry organization, the Coalition for Better Ads, published user research investigating ad formats responsible for "bad ad experiences." The Coalition examined 55 ad formats, of which 12 were deemed unacceptable. These included various full page takeovers (prestitial, postitial, rollover), autoplay videos with sound, pop-ups of all types, and ad density of more than 35% on mobile. Google is supposed to check sites for the forbidden formats and give offenders 30 days to reform or have all their ads blocked in Chrome. Censured sites can purge the offending ads and request reexamination. [...] Some commentators have interpreted ad blocking as the "biggest boycott in history" against the abusive and intrusive nature of online advertising. Now the Coalition aims to slow the adoption of blockers by enacting minimal reforms. Pagefair, an adtech company that monitors adblocker use, estimates 600 million active users of blockers. Some see no ads at all, but most users of the two largest blockers, AdBlock and Adblock Plus, see ads "whitelisted" under the Acceptable Ads program. These companies leverage their position as gatekeepers to the user's eyeballs, obliging Google to buy back access to the "blocked" part of their user base through payments under Acceptable Ads. This is expensive (a German newspaper claims a figure as high as 25 million euros) and is viewed with disapproval by many advertisers and publishers.
