I'm not going to lie to you, my transformation was not easy. It was a slow and painful process. But after I finished it, it felt like nothing before. Thanks to my stubbornness, I was able to truly embrace open source in my life. I gave some minor contributions to some of the worldly-known open source projects like Reddit and the Tor Project. I'm constantly writing about my open source experience on my blog. I started contributing to Opensource.com and to free software magazine written in Serbian language. I even became a guest blogger to a couple of blogs related to open source and IT in general.
“Docker is Linux containers for mere mortals,” Boyd Hemphill is fond of saying. The Director of Evangelism at container application management startup StackEngine organizes Docker Austin meetups, DevOps Days Austin and Container Days events. He has recently given a number of Docker 101 workshops around the country aimed at introducing DevOps professionals to the business advantages of embracing containers and the disposable development environments that they enable.
If your Unix/Linux servers are to be involved in an ISO 27001 audit, there are a lot of things you should be doing ahead of time to ensure that they won't end up generating findings. While there are many things you can do to secure the systems you manage, the key to getting a Unix system to pass an ISO 27001 audit is knowing what the auditors are likely to ask and what they will need to see.
Ubuntu is about to undergo a dramatic overhaul.
No, I don’t mean the huge shift to a converged Unity 8 desktop with the Mir display server, although that’s also coming. Ubuntu is going to move past Deb packages and apt-get in favor of Snappy, which is currently used for cloud images.
Canonical’s Ubuntu isn’t the only project looking to replace Linux packages with something better. The GNOME project is working on a sandboxed, cross-distribution application package framework.
Linux computers are particularly prone to this, and last time several high-profile websites running databases such as Hadoop, including Linkedin, Reddit, and Yelp, were temporarily borked.
GPS trackers don't play nicely either and, given that their accuracy depends on the timings between receiver and satellite, it can make them inaccurate until the problem is addressed.
My goal today was to help you better understand the risks of logging in as root, and how to better take advantage of built-in utilities to limit your rootly super powers. If you insist on having a root account, at least make use of the su - -c [command] option. When possible, make the best use of sudo to maintain tight control over access to super powers. Remember, with power comes responsibility. Use your super powers wisely!
Right now, my refrigerator uses Linux, as does the thermostat that controls the climate of my home. The washer and dryer components and firmware with the touch control screens are built on Linux (Amana if you want to look it up). The navigation system on my old Ford Explorer is based on Linux. Our home entertainment center has a touch screen control based on Ubuntu.
