Linux System Administration: First Tasks

Filed under
Linux

You might know how to write code or build applications, but do you know what is required of a good Linux sysadmin?

Linux system administration has a place of its own in the hierarchy of information technology specializations. Some people excel in special areas of free software technology but haven't needed to learn system administration. For example, you may specialize in configuring e-mail or writing applications using Apache and MySQL. You may focus only on Domain Names Services and know esoteric ways of setting up servers on provider lines that frequently change IP addresses. But if I asked you to babysit a busy server or servers, you might not have the temperament or have learned the plethora of skills required to do so.

The above does not mean that good system administrators do not excel in areas such as configuring Apache, maintaining DNS zone files or writing Perl Scripts. It simply means that if you want to work as a system administrator in the Linux world, you need to know how to do everything from installing a server to securing the filesystem from mischievous crackers on the Internet. In between, you need to prepare your system to recover from the myriad ways a server can fail.

Consider, for example, a case in which you find that one of the Web sites you manage has gone down; the server has locked up and nothing works. How do you recover in the fastest possible way?

Local Motors: Cars Should be Open Source Hardware

There are several open source initiatives already underway to enable open source software in cars, including the Linux Foundation's Automotive Grade Linux group. But so far those projects have been mostly focused on the in-vehicle infotainment centers, which provide the user interface for the car and its entertainment system but not to the car's internal systems. That's not enough to fully transform the industry, Rogers said. “You need to know how to hack the hardware in the car, because that's what defines how you can drive it and how you can run it.” Read more

Intel Sandy Bridge Gets A Surprise Boost From Linux 3.17

Besides the recent work to support OpenGL Geometry Shaders for Sandy Bridge in Mesa, users of Intel "Sandy Bridge" HD Graphics can also be thankful for the forthcoming Linux 3.17 kernel. Early testing of Linux 3.17 has revealed that for at least some Intel Sandy Bridge hardware are OpenGL performance improvements with the newer kernel code. Read more

Open Source Okavango14: The Heartbeat of the Delta

We can hear this heartbeat by listening to what the environment tells us through sensors and testing. I proposed that we build low cost sensors using open source hardware and software. In recent years there has been quite a disruption in computing ability as a result of the prevalence of smartphones. Increasingly small and powerful components and processors have created an opportunities that we would have never thought possible. One of the results of that is the single-board Raspberry Pi computer. Originally, the Raspberry Pi was created to enable students to learn hardware and software development. For the Okavango Wilderness Project, we are using them to take environmental readings and send those to us for inclusion into the Into The Okavango website. Jer will cover this more in his expedition post. We are using them to measure water temperature, pH, conductivity, total dissolved solids, salinity, and specific gravity. Read more

Kochi innovator Arvind Sanjeev makes Google Glass clone for Rs 4,500

Instead of commercializing the product and with the intention of contributing to the community, Sanjeev posted a blog explaining how his 'Smart Cap' can be built by anyone using opensource hardware such as a Rasberry Pi computer, an Arduino board and Android software. Read more
