  • Ubuntu 18.04 Install and First Look

    The long anticipated Ubuntu 18.04 “Bionic Beaver” Long Term Support (LTS) release has arrived… Let’s install it and take a look around.

  • Canonical Managed Cloud adds data protection and recovery with Trilio

    Canonical and Trilio announced today a partnership agreement to deliver TrilioVault backup and recovery solutions as part of BootStack, Canonical’s fully managed OpenStack private cloud solution. TrilioVault will also be made available as an option to Ubuntu Advantage support customers. As a result, users already taking advantage of the Ubuntu platform for their OpenStack deployment now have seamless access to the only OpenStack-native data protection solution on the market.

    Together, the two companies are pushing the boundaries of enterprise OpenStack clouds to become increasingly easier to build, simpler to manage, and more reliable in the event of a disaster.

  • Ubuntu's Shuttleworth Creates Controversy with OpenStack Summit Vancouver Keynote

    The OpenStack Foundation is facing a bit of drama and controversy as it deals with issues related to a keynote delivered by Ubuntu Linux founder, Mark Shuttleworth at the OpenStack Summit here on May 21.

    Typically the OpenStack Foundation posts videos of all its session online within 24 hours, but with the Shuttleworth keynote, the video was apparently posted and then promptly removed. During his keynote, Shuttleworth took direct aim at his OpenStack competitor Red Hat, which apparently made some people in the OpenStack Summit community uncomfortable.

Offline Computing – 10 Apps for the Digital Nomad

Filed under
Software

In today’s always-connected, constantly-inturrupted world, it can often be rewarding to go offline. Disconnecting from the Internet doesn’t mean you have to buy a yurt, live on beans, and get no work done though!

While there’s a ton of great apps in the Snap store which rely on a connection to function, there’s also a lot you can do offline. So whether you’re taking a trip that doesn’t offer (reasonably priced) in-flight wifi, or want to live life the digital nomad style, we’ve got some apps for you!

These all work offline, so once installed you can work, study & play without a connection.

Finally: Historic Eudora email code goes open source

Filed under
OSS

The source code to the Eudora email client is being released by the Computer History Museum, after five years of discussion with the IP owner, Qualcomm.

The Mac software was well loved by early internet adopters and power users, with versions appearing for Palm, Newton and Windows. At one time, the brand was so synonymous with email that Lycos used Eudora to brand its own webmail service. As the Mountain View, California museum has noted, "It’s hard to overstate Eudora’s popularity in the mid-1990s."

  • More Meltdown/Spectre Variants
  • Spectre V2 & Meltdown Linux Fixes Might Get Disabled For Atom N270 & Other In-Order CPUs

    There's a suggestion/proposal to disable the Spectre Variant Two and Meltdown mitigation by default with the Linux kernel for in-order CPUs.

    If you have an old netbook still in use or the other once popular devices powered by the Intel Atom N270 or other in-order processors, there may be some reprieve when upgrading kernels in the future to get the Spectre/Meltdown mitigation disabled by default since these CPUs aren't vulnerable to attack but having the mitigation in place can be costly performance-wise.

  • Linux 4.17 Lands Initial Spectre V4 "Speculative Store Bypass" For POWER CPUs

    Following yesterday's public disclosure of Spectre Variant Four, a.k.a. Speculative Store Bypass, the Intel/AMD mitigation work immediately landed while overnight the POWER CPU patch landed.

  • New Variant Of Spectre And Meltdown CPU Flaw Found; Fix Affects Performance
  • Ubuntu 18.04 LTS Gets First Kernel Update with Patch for Spectre Variant 4 Flaw

    Canonical released the first kernel security update for its Ubuntu 18.04 LTS (Bionic Beaver) operating system to fix a security issue that affects this release of Ubuntu and its derivatives.

    As you can imagine, the kernel security update patches the Ubuntu 18.04 LTS (Bionic Beaver) operating system against the recently disclosed Speculative Store Buffer Bypass (SSBB) side-channel vulnerability, also known as Spectre Variant 4 or CVE-2018-3639, which could let a local attacker expose sensitive information in vulnerable systems.

  • RHEL and CentOS Linux 7 Receive Mitigations for Spectre Variant 4 Vulnerability

    As promised earlier this week, Red Hat released software mitigations for all of its affected products against the recently disclosed Spectre Variant 4 security vulnerability that also affects its derivatives, including CentOS Linux.

    On May 21, 2018, security researchers from Google Project Zero and Microsoft Security Response Center have publicly disclosed two new variants of the industry-wide issue known as Spectre, variants 3a and 4. The latter, Spectre Variant 4, is identified as CVE-2018-3639 and appears to have an important security impact on any Linux-based operating system, including all of its Red Hat's products and its derivatives, such as CentOS Linux.

LXQt 0.13 Desktop Environment Officially Released, It's Coming to Lubuntu 18.10

For starters, all of LXQt's components are now ready to be built against the recently released Qt 5.11 application framework, and out-of-source-builds are now mandatory. LXQt 0.13.0 also disabled the menu-cached functionality, making it optional from now on in both the panel and runner, thus preventing memory leaks and avoiding any issues that may occur when shutting down or restarting LXQt.

Best Linux Laptops of 2018

Filed under
Linux

There was a time, not so long ago, when Linux was seen as an outcast operating system, and indeed one that was labelled as a ‘cancer’ by Microsoft’s former CEO Steve Ballmer.

Times have now changed as the operating system - which launched in September 1991, has made some serious inroads in the server market, then in the cloud – not forgetting that it underpins the most popular ecosystem out there: Android on smartphones.

Because none of the main notebook vendors – bar Dell – offer Linux as an OS option, this leaves other smaller companies the ability to carve a niche for themselves.

  • How open-source computing is making AI affordable

    computing and the cloud have brought many previously unaffordable IT options to small and medium-sized enterprises (SMEs). The same is becoming true of artificial intelligence (AI), although it brings new challenges to all sizes of company.

    Even though many of the commercial, high-profile products are aimed at Global 2000 companies, and others marketed at SMEs are perhaps heavier on hype than intelligence, the smarter smaller organisations can learn, build on and use AI techniques right now, with those same open-source and

Do European Governments Publish Open Source Software?

Filed under
OSS

From time to time I come across news articles about Governmental bodies in Europe adopting the use of Open Source Software. This seems to be a slowly increasing trend. But if European Governments make software for themselves, or are having it made for them, do they publish that software as Open Source?

This was a question that came up in a meeting at one of my clients. To find an answer, I asked my friends at the FSFE NL-team and did a Quick Scan. Here are the results.

The short answer: Yes, they do!

The longer answer: read on.

    Since Redis has not authorized the disclosure of the attack method of root authority of Linux system, because of its ease-of-use, the hacking behaviors of mining and scanning of Linux services by using this issue have been endless. Among the many cases that handle this problem to invade the server for black production, there is a class of mining that USES this problem and can automatically scan the infected machine with pnscan.

    The Turla cyberespionage group has implemented some new tactics over the last few months incorporating some open-source exploitation tools instead of relying solely on their own creations to run campaigns.

    ESET researchers found that starting in March the Turla has been leveraging the open-source framework Metasploit to drop the group's proprietary Mosquito backdoor. The group has periodically used open-source hacking tools for other tasks, but ESET believes the group has never before used Metasploit as a first stage backdoor.

    Crackers are so to speak the evil hackers. Although these very often also do not offer the possibilities in order to do justice to the descriptions of the media. Then there are the would-be hackers, also called ScriptKiddies who use themTrojan2 and pre-programmed programs to get into computers and do damage.

    The “Kiddie” leads is a departure from the English “kid” (child), since young people are often behind such attacks. Due to their young age and lack of experience, ScriptKiddies often do not even know what they are doing. Let me give you an example. I have seen ScriptKiddies that use methods to intrude into Windows NT Calculator tried to break into a Linux machine. ScriptKiddies are often bored teenagers who try to have fun with the first tool. These tools are usually so simply knitted that actually, each normal, somewhat educated user can serve them.
