Tackling the most important issue in a DevOps transformation

15 hours 23 min ago

You've been appointed the DevOps champion in your organisation: congratulations. So, what's the most important issue that you need to address?

It's the technology—tools and the toolchain—right? Everybody knows that unless you get the right tools for the job, you're never going to make things work. You need integration with your existing stack (though whether you go with tight or loose integration will be an interesting question), a support plan (vendor, third party, or internal), and a bug-tracking system to go with your source code management system. And that's just the start.

How to configure an Apache web server

Thursday 22nd of February 2018 08:02:00 AM

I have hosted my own websites for many years now. Since switching from OS/2 to Linux more than 20 years ago, I have used Apache as my server software. Apache is solid, well-known, and quite easy to configure for a basic installation. It is not really that much more difficult to configure for a more complex setup, such as multiple websites.

5 rules for having genuine community relationships

Thursday 22nd of February 2018 08:00:00 AM

As I wrote in the first article of this three-part series on the power and importance of communities, building a community of passionate and committed members is difficult. When we launched the NethServer community, we realized early that to play the open source game, we needed to follow the open source rules. No shortcuts. We realized we had to convert the company in an open organization and start to work out in the open.

3 reasons to say 'no' in DevOps

Thursday 22nd of February 2018 08:00:00 AM

DevOps, it has often been pointed out, is a culture that emphasizes mutual respect, cooperation, continual improvement, and aligning responsibility with authority.

Instead of saying no, it may be helpful to take a hint from improv comedy and say, "Yes, and..." or "Yes, but...". This opens the request from the binary nature of "yes" and "no" toward having a nuanced discussion around priority, capacity, and responsibility.

However, sometimes you have no choice but to give a hard "no." These should be rare and exceptional, but they will occur.

Create a wiki on your Linux desktop with Zim

Wednesday 21st of February 2018 08:02:00 AM

There's no denying the usefulness of a wiki, even to a non-geek. You can do so much with one—write notes and drafts, collaborate on projects, build complete websites. And so much more.

Getting started with SQL

Wednesday 21st of February 2018 08:01:00 AM

Building a database using SQL is simpler than most people think. In fact, you don't even need to be an experienced programmer to use SQL to create a database. In this article, I'll explain how to create a simple relational database management system (RDMS) using MySQL 5.6. Before I get started, I want to quickly thank SQL Fiddle, which I used to run my script. It provides a useful sandbox for testing simple scripts.

3 warning flags of DevOps metrics

Wednesday 21st of February 2018 08:01:00 AM

Metrics. Measurements. Data. Monitoring. Alerting. These are all big topics for DevOps and for cloud-native infrastructure and application development more broadly. In fact, acm Queue, a magazine published by the Association of Computing Machinery, recently devoted an entire issue to the topic.

How Kubernetes became the solution for migrating legacy applications

Tuesday 20th of February 2018 04:30:00 PM

In the early days of the internet, if you wanted to launch an application, you had to buy or rent hardware. This was a physical server or a rack of servers, and you needed one server per application, so it was expensive. In 2001, VMware came out with virtualization—software that allowed users to run multiple applications on the same hardware. This meant you could split up a single box into multiple virtual boxes, each running its own environment and applications. The cost savings for businesses were tremendous.

How to format academic papers on Linux with groff -me

Tuesday 20th of February 2018 08:03:00 AM

I was an undergraduate student when I discovered Linux in 1993. I was so excited to have the power of a Unix system right in my dorm room, but despite its many capabilities, Linux lacked applications. Word processors like LibreOffice and OpenOffice were years away. If you wanted to use a word processor, you likely booted your system into MS-DOS and used WordPerfect, the shareware GalaxyWrite, or a similar program.

How Linux became my job

Monday 19th of February 2018 08:02:00 AM

I've been using open source since what seems like prehistoric times. Back then, there was nothing called social media. There was no Firefox, no Google Chrome (not even a Google), no Amazon, barely an internet. In fact, the hot topic of the day was the new Linux 2.0 kernel. The big technical challenges in those days?

Perl hashes and arrays: The basics

Monday 19th of February 2018 08:01:00 AM

I get asked from time to time why I enjoy programming in Perl so much. Ask me in person, and I'll wax poetic about the community of people involved in Perl—indeed, I have done so more than once here on Opensource.com already, and I make no secret of the fact that many of my closest friends are Perl mongers.

How the Grateful Dead were a precursor to Creative Commons licensing

Monday 19th of February 2018 08:00:00 AM

From its founding in 1965, the Grateful Dead was always an unusual band. Rising amidst the counterculture movement in the San Francisco Bay Area, the Grateful Dead’s music had roots in multiple styles and genres but did not lend itself to easy categorization. Was it psychedelic? Folk? Blues? Country? Yes, it was all of these and more. The band frequently performed well-known public domain songs, but they made the songs their own.

The knitting printer and more art with open source

Friday 16th of February 2018 08:01:00 AM

For several years, linux.conf.au, a week-long conference (held this year from January 22-26), has held "miniconfs" offering space for tech community niche groups to share their inventions and ideas. In 2018, 12 miniconfs were held on the first two days of the conference, and the Art + Tech miniconf took the concept to the next level with an entire day of 11 talks about making art with tech, as well as an art exhibition head during the conference.

GNOME and Fedora

  • RFC: Integrating rsvg-rs into librsvg
    I have started an RFC to integrate rsvg-rs into librsvg. rsvg-rs is the Rust binding to librsvg. Like the gtk-rs bindings, it gets generated from a pre-built GIR file.
  • 1+ year of Fedora and GNOME hardware enablement
    A year and a couple of months ago, Christian Schaller asked me to pivot a little bit from working full time on Fleet Commander to manage a new team we were building to work on client hardware enablement for Fedora and GNOME with an emphasis on upstream. The idea was to fill the gap in the organization where nobody really owned the problem of bringing up new client hardware features vertically across the stack (from shell down to the kernel), or rather, ensure Fedora and GNOME both work great on modern laptops. Part of that deal was to take over the bootloader and start working closer to customers and hardware manufacturing parnters.
  • Fedora Atomic Workstation: Works on the beach
    My trip is getting really close, so I decided to upgrade my system to rawhide. Wait, what ? That is usually what everybody would tell you not to do. Rawhide has this reputation for frequent breakage, and who knows if my apps will work any given day. Not something you want to deal with while traveling.

Why You Shouldn’t Use Firefox Forks (and Proprietary Opera)

  • Why You Shouldn’t Use Firefox Forks Like Waterfox, Pale Moon, or Basilisk
    Mozilla Firefox is an open source project, so anyone can take its code, modify it, and release a new browser. That’s what Waterfox, Pale Moon, and Basilisk are—alternative browsers based on the Firefox code. But we recommend against using any of them.
  • Opera Says Its Next Opera Release Will Have the Fastest Ad Blocker on the Block
    Opera Software promoted today its upcoming Opera 52 web browser to the beta channel claiming that it has the faster ad blocker on the market compared to previous Opera release and Google Chrome. One of the key highlights of the Opera 52 release will be the improved performance of the built-in ad blocker as Opera claims to have enhanced the string matching algorithm of the ad blocker to make it open web pages that contain ads much faster than before, and, apparently than other web browsers, such as Chrome.

Graphics: Glxinfo, ANV, SPIR-V

  • Glxinfo Gets Updated With OpenGL 4.6 Support, More vRAM Reporting
    The glxinfo utility is handy for Linux users in checking on their OpenGL driver in use by their system and related information. But it's not often that glxinfo itself gets updated, except that changed today with the release of mesa-demos-8.4.0 as the package providing this information utility. Mesa-demos is the collection of glxinfo, eglinfo, glxgears, and utilities related to Mesa. With the Mesa-demos 8.4.0 it is predominantly glxinfo updates.
  • Intel ANV Getting VK_KHR_16bit_storage Support Wrapped Up
    Igalia's Jose Maria Casanova Crespo sent out a set of patches today for fixes that allow for the enabling of the VK_KHR_16bit_storage extension within Intel's ANV Vulkan driver. The patches are here for those interested in 16-bit storage support in Vulkan. This flips on the features for storageBuffer16BitAccess, uniformAndStorageBuffer16BitAccess, storagePushConstant16 and the VK_KHR_16bit_storage extension. This support is present for Intel "Gen 8" Broadwell graphics and newer. Hopefully the work will be landing in Mesa Git soon.
  • SPIR-V Support For Gallium3D's Clover Is Closer To Reality
    It's been a busy past week for open-source GPU compute with Intel opening up their new NEO OpenCL stack, Karol Herbst at Red Hat posting the latest on Nouveau NIR support for SPIR-V compute, and now longtime Nouveau contributor Pierre Moreau has presented his latest for SPIR-V Clover support. Pierre has been spending about the past year adding SPIR-V support to Gallium3D's "Clover" OpenCL state tracker. SPIR-V, of course, is the intermediate representation used now by OpenCL and Vulkan.

Security: Updates, Tinder, FUD and KPTI Meltdown Mitigation

  • Security updates for Friday
  • Tinder vulnerability let hackers [sic] take over accounts with just a phone number

    The attack worked by exploiting two separate vulnerabilities: one in Tinder and another in Facebook’s Account Kit system, which Tinder uses to manage logins. The Account Kit vulnerability exposed users’ access tokens (also called an “aks” token), making them accessible through a simple API request with an associated phone number.

  • PSA: Improperly Secured Linux Servers Targeted with Chaos Backdoor [Ed: Drama queen once again (second time in a week almost) compares compromised GNU/Linux boxes to "back doors"]
    Hackers are using SSH brute-force attacks to take over Linux systems secured with weak passwords and are deploying a backdoor named Chaos. Attacks with this malware have been spotted since June, last year. They have been recently documented and broken down in a GoSecure report.
  • Another Potential Performance Optimization For KPTI Meltdown Mitigation
    Now that the dust is beginning to settle around the Meltdown and Spectre mitigation techniques on the major operating systems, in the weeks and months ahead we are likely to see more performance optimizations come to help offset the performance penalties incurred by mitigations like kernel page table isolation (KPTI) and Retpolines. This week a new patch series was published that may help with KPTI performance.
