Linux Foundation releases business open source basics ebook

By Lotte Nielsen | Blog

Want to know how your business can get the most from open source? This free ebook can help.

Developers know that open source is great. Even Microsoft is now on the open-source bandwagon. But, outside of the IT department, many companies don’t understand why and how open source can help their businesses. The Linux Foundation has the answers you need in its new free Open Source Software Basics ebook.

„Organizations have begun to realize that as they adopt more open-source software, they need to establish processes for everything from selecting software — to deploying it, to ensuring license compliance,“ said Linux Foundation executive director Jim Zemlin at the Open Source Leadership Summit in Lake Tahoe, Calif. „The benefits of adopting and contributing back to open source are immense, but more education is required to fully realize those advantages.“

Linux poll results: And the winners are…

By Lotte Nielsen | Blog

The members of LinuxQuestions have spoken about their favorite Linux and open-source programs. Their favorite Linux? Would you believe it’s Slackware?

The votes are in. LinuxQuestions, one of the largest Linux groups with 550,000 members, has just posted the results from its latest poll. The winner for the most popular desktop distribution? Slackware! Slackware!? Yes, one of the oldest of Linux distributions won with just over 16 percent of the vote. If that sounds a little odd, it is. On DistroWatch, a site that covers Linux distributions like paint, the top Linux desktop distros are Mint, Debian, Ubuntu, openSUSE, and Manjaro. Slackware comes in 28th place.

darktable 2.2.3 Open-Source RAW Image Editor Brings Subtraction of Black Levels

By Lotte Nielsen | Blog

It seems to us that the developers of the darktable open-source and cross-platform RAW image editor are very active lately, and they now announced the availability of the third maintenance update to the major darktable 2.2 stable series of the application.

darktable 2.2.3 comes only two days after the second point release (darktable 2.2.2), which means that it’s a very small update addressing only a handful of issues. For example, it improves subtraction of black levels by making sure the even- or oddness of the RAW crop origin point is respected.

The new darktable 2.2 update also fixes various user interface quirks for the Collection module and patches a fatal crash that occurred when attempting to generate previews for medium megapixel count of approximately 16MP on RAW Bayer images, so updating is recommended for all users.

Bigger, better LibreOffice 5.3 released for the cloud

By Lotte Nielsen | Blog

The latest version of LibreOffice is out now for Linux, macOS, Windows, and, at long last, the cloud.

Almost two years ago, The Document Foundation announced it was going to bring LibreOffice to the cloud. With the release of LibreOffice 5.3, that day has finally come. LibreOffice, the popular open-source office suite, is arguably the best desktop-based office suite. Why? Italo Vignoli, co-founder of The Document Foundation, explains:

1. Independence from a single vendor, who’s interested in locking-in users to secure their bottom line. LibreOffice is free software.

2. The chance to influence LibreOffice’s development — either by contributing directly or by paying contributors for the development of specific features. For a large deployment, the cost is usually lower than the purchase of MS Office licenses.

3. Reduction of interoperability costs. Since its truly open and standard document format, Open Document Format (ODF) is the same across applications and operating systems.

4. Lower document security, thanks to ODF files intrinsically stronger security, compared to Microsoft’s Office’s Open XML (OOXML) since OOXML files often contain binary blobs. This makes it easier to inject them with malware.

5. Lower training costs, as LibreOffice’s user interface is consistent across operating systems.

Performance made easy with Linux containers

By Lotte Nielsen | Allgemein

Performance for an application determines how quickly your software can complete the intended task.

It answers questions about the application, such as:

  • Response time under peak load
  • Ease of use, supported functionality, and use cases compared to an alternative
  • Operational costs (CPU usage, memory needs, data throughput, bandwidth, etc.)

The value of this performance analysis extends beyond the estimation of the compute resources needed to serve the load or the number of application instances needed to meet the peak demand. Performance is clearly tied to the fundamentals of a successful business. It informs the overall user experience, including identifying what slows down customer-expected response times, improving customer stickiness by designing content delivery optimized to their bandwidth, choosing the best device, and ultimately helping enterprises grow their business.

Important CentOS 7 Linux Kernel Security Patch Released, 3 Vulnerabilities Fixed

By Lotte Nielsen | Blog

CentOS developer and maintainer Johnny Hughes is announcing the availability of a new, important Linux kernel security update for the CentOS 7 series of operating systems.

As for the other two security issues, CVE-2016-6828 is a use-after-free vulnerability discovered in Linux kernel’s tcp_xmit_retransmit_queue, as well as other tcp_* functions, allowing an attacker to send a false selective acknowledgment to current network connections, possibly resetting them.

On the other hand, CVE-2016-9555 is a security flaw discovered in Linux kernel’s Stream Control Transmission Protocol (SCTP) transport-layer protocol implementation, which could allow a remote attacker to crash the vulnerable system by triggering an out-of-bounds read with an offset of up to 64kB.
