5 military phrases for DevOps practitioners

Thursday 5th of July 2018 07:01:00 AM

The U.S. military is known for quite a few things, including its excessive and fascinating use of acronyms, euphemisms, and colorful phrases to describe certain situations. But many of these terms are applicable to other areas of life, including many non-military jobs.

Following are five phrases from the armed forces that I think DevOps practitioners should adopt.

Open source money: Bitcoin, blockchain, and free software

Wednesday 4th of July 2018 07:01:00 AM

Whether you believe that blockchain technology is poised to change the world or that it is a flash in the pan, one thing is sure: Technical and legal questions about blockchain are on everyone's mind today. People often wonder: Is Bitcoin "open source"? But this question arises from confusion about three separate concepts: blockchains, cryptocurrencies, and open source software.

10 killer tools for the admin in a hurry

Tuesday 3rd of July 2018 07:02:00 AM

Administering networks and systems can get very stressful when the workload piles up. Nobody really appreciates how long anything takes, and everyone wants their specific thing done yesterday.

So it's no wonder so many of us are drawn to the open source spirit of figuring out what works and sharing it with everyone. Because, when deadlines are looming, and there just aren't enough hours in the day, it really helps if you can just find free answers you can implement immediately.

How to make a career move from proprietary to open source technology

Tuesday 3rd of July 2018 07:01:00 AM

I started my journey as a software engineer at Northern Telecom, where I developed proprietary software for carrier-grade telephone switches. Although I learned Pascal while in college, at Northern Telecom I was trained in a proprietary programming language based on C. I also used a proprietary operating system and a proprietary version-control software.

What Game of Thrones teaches us about working openly

Tuesday 3rd of July 2018 07:00:00 AM

You might think the only synergy one can find in Game of Thrones is that between Jaime Lannister and his sister, Cersei. Characters in the show's rotating cast don't see many long term relationships, as they're killed off, betrayed, and otherwise trading loyalty in an effort to stay alive. Even the Stark children, siblings suffering from the deaths of their parents, don't really get along most of the time.

My first sysadmin mistake

Monday 2nd of July 2018 07:01:00 AM

If you work in IT, you know that things never go completely as you think they will. At some point, you'll hit an error or something will go wrong, and you'll end up having to fix things. That's the job of a systems administrator.

As humans, we all make mistakes. Sometimes, we are the error in the process, or we are what went wrong. As a result, we end up having to fix our own mistakes. That happens. We all make mistakes, typos, or errors.

An insider's look at drafting the GPLv3 license

Friday 29th of June 2018 07:01:00 AM

Last year, I missed the opportunity to write about the 10th anniversary of GPLv3, the third version of the GNU General Public License. GPLv3 was officially released by the Free Software Foundation (FSF) on June 29, 2007—better known in technology history as the date Apple launched the iPhone. Now, one year later, I feel some retrospection on GPLv3 is due. For me, much of what is interesting about GPLv3 goes back somewhat further than 11 years, to the public drafting process in which I was an active participant.

What proprietary tool do you wish had an open source alternative?

Thursday 28th of June 2018 07:03:00 AM

Whether it's that one program that's keeping you from making the switch over to using the Linux desktop, a phone app that keeps pestering you with needless notifications, a terrible web interface that looks like it came straight out of the 90s, or something else, there's probably some closed-source proprietary tool out that that you'd love to rid your life of.

Blockchain evolution: A quick guide and why open source is at the heart of it

Thursday 28th of June 2018 07:02:00 AM

It isn't uncommon, when working on a new version of an open source project, to suffix it with "-ng", for "next generation." Fortunately, in their rapid evolution blockchains have so far avoided this naming pitfall. But in this evolutionary open source ecosystem, changes have been abundant, and good ideas have been picked up, remixed, and evolved between many different projects in a typical open source fashion.

  • Four top open source SIEM tools you should know
    With open source SIEM tools, organizations can test out certain capabilities and reduce cost barriers before expanding their product investments. Depending on what functions you're interested in, there is a variety of software to choose from. [...] Another choice for open source SIEM tools is Apache Metron. ELK Stack is a general purpose log and data parsing tool; Apache Metron focuses squarely on security. Apache Metron provides four main capabilities. First, it offers long-term, cost-effective storage of telemetry data through its security data lake feature. Second, it features an extensible framework that collects data from a variety of sources and supports any future endpoints. Third, Metron performs normal SIEM tasks, such as data ingest and threat alerts. The fourth capability is threat intelligence driven by machine learning-based anomaly detection.

  • Emacs & TLS
    A recent query about the status of network security (TLS settings in particular) in Emacs led to a long thread in the emacs-devel mailing list. That thread touched on a number of different areas, including using OpenSSL (or other TLS libraries) rather than GnuTLS, what kinds of problems should lead to complaints out of the box, what settings should be the default, and when those settings could change for Emacs so as not to discombobulate users. The latter issue is one that lots of projects struggle with: what kinds of changes are appropriate for a bug-fix release versus a feature release. For Emacs, its lengthy development cycle, coupled with the perceived urgency of security changes, makes that question even more difficult.

Security: Spectre V1, Gentoo, Google’s Servers and Denuvo DRM

  • Spectre V1 defense in GCC
  • Signing and distributing Gentoo
    The compromise of the Gentoo's GitHub mirror was certainly embarrassing, but its overall impact on Gentoo users was likely fairly limited. Gentoo and GitHub responded quickly and forcefully to the breach, which greatly limited the damage that could be done; the fact that it was a mirror and not the master copy of Gentoo's repositories made it relatively straightforward to recover from. But the black eye that it gave the project has led some to consider ways to make it even harder for an attacker to add malicious content to Gentoo—even if the distribution's own infrastructure were to be compromised. Unlike other distributions, Gentoo is focused on each user building the software packages they want using the Portage software-management tool. This is done by using the emerge tool, which is the usual interface to Portage. Software "packages" are stored as ebuilds, which are sets of files that contain the information and code needed by Portage to build the software. The GitHub compromise altered the ebuilds for three packages to add malicious content so that users who pulled from those repositories would get it. Ebuilds are stored in the /usr/portage directory on each system. That local repository is updated using emerge --sync (which uses rsync under the hood), either from Gentoo's infrastructure or one of its mirrors. Alternatively, users can use emerge-webrsync to get snapshots of the Gentoo repository, which are updated daily. Snapshots are individually signed by the Gentoo infrastructure OpenPGP keys, while the /usr/portage tree is signed by way of Manifest files that list the hash of each file in a directory. The top-level Manifest is signed by the infrastructure team, so following and verifying the chain of hashes down to a particular file (while also making sure there are no unlisted files) ensures that the right files are present in the tree.

  • Pirates Punish Denuvo-Protected Games With Poor Ratings

    Denuvo's anti-piracy technology is a thorn in the side of game pirates. While it has been defeated on several occasions recently, the strict anti-piracy measures have not been without consequence. According to new research, Denuvo has frustrated pirates to a point where they sabotage reviews on Metacritic, leading to significantly lower ratings for protected games.
