Tomasz Jokiel from Porteus Solutions announced the release of the Gentoo-based Porteus Kiosk 4.5 operating system designed for web terminals, which brings numerous improvements, updated components, and new functionality.

First and foremost, Porteus Kiosk 4.5.0 bumps the Linux kernel version from the long-term supported Linux 4.9 series, which was used in the previous release, to the Linux 4.12 branch, shipping with Linux kernel 4.12.10 by default, thus adding an extra layer of hardware support to the free and open-source kiosk operating system for public access computers.

  • 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

    Google has today announced Chrome Enterprise as a subscription service to take Chrome OS and Chromebooks into more work environments.

    Chrome Enterprise makes Chrome OS more friendly for professional work environments and lets IT/administrators manage Chrome extensions, printers, handle operating system updates, and provides other features like single sign-on support and more. 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.

  • How Open Source Tech Helps Feds Solve Workforce Turnover Issues
    Just as a mainframe from decades ago might be ready for retirement, the IT staff who originally procured and installed that system might also be preparing for a new phase in their lives. It’s up to the current and next generation of government IT employees to prepare for that eventuality, but there are indications they may not be ready, despite evidence that older IT professionals are retiring or will soon be leaving their positions. Unfortunately, a skills gap exists even among younger generation IT workers. Agencies are scrambling to find personnel with expertise in cloud service management, cybersecurity, technical architecture and legacy technologies, such as common business-oriented language (COBOL) and mainframes, among other areas. At the same time that many workers are getting ready to retire, leaving behind a wealth of knowledge, many younger IT professionals are struggling to gain the knowledge they will need to take their agencies into the future.

Today, Overclock Labs, which was founded two years ago, is coming out of stealth and announcing that it raised a $1.3 million seed round from a number of Silicon Valley angel investors and CrunchFund — the fund that shares a bit of its name and history with TechCrunch but is otherwise completely unaffiliated with the blog you are currently reading.

The law center has demanded the cancellation of a trademark held by the conservancy.

Security: Linux, Free Software Principles, Microsoft and Intel

  • Some 'security people are f*cking morons' says Linus Torvalds
    Linux overlord Linus Torvalds has offered some very choice words about different approaches security, during a discussion about whitelisting features proposed for version 4.15 of the Linux kernel. Torvalds' ire was directed at open software aficionado and member of Google's Pixel security team Kees Cook, who he has previously accused of idiocy. Cook earned this round of shoutiness after he posted a request to “Please pull these hardened usercopy changes for v4.15-rc1.”
  • Free Software Principles
    Ten thousand dollars is more than $3,000, so the motives don't add up for me. Hutchins may or may not have written some code, and that code may or may not have been used to commit a crime. Tech-literate people, such as the readers of Linux Magazine, understand the difference between creating a work and using it to commit a crime, but most of the media coverage – in the UK, at least – has been desperate to follow the paradigm of building a man up only to gleefully knock him down. Even his achievement of stopping WannaCry is decried as "accidental," a word full of self-deprecating charm when used by Hutchins, but which simply sounds malicious in the hands of the Daily Mail and The Telegraph.
  • New warning over back door in Linux
    Researchers working at Russian cyber security firm Dr Web claim to have found a new vulnerability that enables remote attackers to crack Linux installations virtually unnoticed. According to the anti-malware company, cyber criminals are getting into the popular open-source operating system via a new backdoor. This, they say, is "indirect evidence" that cyber criminals are showing an increasing interest in targeting Linux and the applications it powers. The trojan, which it's calling Linux.BackDoor.Hook.1, targets the library libz primarily. It offers compression and extraction capabilities for a plethora of Linux-based programmes.

Though most of the suggestions cost little or nothing to implement and will strike security professionals as common sense, notorious attacks including the leak of the emails of Hillary Clinton’s campaign chair, John Podesta, have succeeded because basic security practices were not followed.

Intel found the vulnerabilities after conducting a security audit spurred by recent research. It has also published a Detection Tool so Windows and Linux administrators can check their systems to see if they're exposed.
