The Bash shell is a fundamental Linux tool and, in this era of containers and clusters and microservices, good old-fashioned Linux system administration skills are as relevant as ever. Today, we'll learn about running other command shells, Bash built-ins, configuration files, and shell expansion.
Remotely-distributed system administration teams provide around-the-clock coverage without anyone losing sleep, and have the benefit of drawing from a global talent pool. The OpenStack global infrastructure team relies on these five open source tools to communicate, and to coordinate our work.
In our Getting Started With Raspberry Pi series, we’ve introduced you to the basics of Pi, told you how to get everything you need, and help you boot a basic operating system. But, Raspberry Pi is much more than that. You can use it as a TOR proxy router, build your own PiPhone, and even install Windows 10 IoT.
This little device comes with lots of flexibility, that allows it to be used in multiple applications. Well, did you ever think about wearing your Raspberry Pi? If your answer is NO, I won’t be surprised.
If you imagine a scenario where Raspberry Pi is used to build a smartwatch, it would look too bulky. Well, that’s the thing about making geeky things that set you apart from the regular crowd, right?
Once upon a time, there was no Linux. No, really! It did not exist. It was not like today, with Linux everywhere. There were multiple flavors of Unix, there was Apple, and there was Microsoft Windows.
When it comes to Windows, the more things change, the more they stay the same. Despite adding 20+ gigabytes of gosh-knows-what, Windows is mostly the same. (Except you can't drop to a DOS prompt to get actual work done.) Hey, who remembers Gorilla.bas, the exploding banana game that came in DOS? Fun times! The Internet never forgets, and you can play a Flash version on Kongregate.com.
Apple changed, evolving from a friendly system that encouraged hacking to a sleek, sealed box that you are not supposed to open, and that dictates what hardware interfaces you are allowed to use. 1998: no more floppy disk. 2012: no more optical drive. The 12-inch MacBook has only a single USB Type-C port that supplies power, Bluetooth, Wi-Fi, external storage, video output, and accessories. If you want to plug in more than one thing at a time and don't want to tote a herd of dongles and adapters around with you, too bad. Next up: The headphone jack. Yes, the one remaining non-proprietary standard hardware port in Apple-land is doomed.
For a number of months there's been an effort to replace the CFQ I/O scheduler with BFQ inside the Linux kernel. That isn't happening for the current Linux 4.8 cycle, but new patches were published today in pursuing this goal.
The input updates for Linux 4.8 bring support for the Microsoft Surface 3 touchscreen controller, among other improvements.
The Raspberry Pi was given consideration, but Google Research chose the BeagleBone on the strength of its PRUs, which can access all 512MB of the BeagleBone’s system RAM. “This lets us dedicate the PRUs to the time-sensitive and repetitive task of reading each sample out of an external ADC, while the main CPU lets us use the data with the GNU/Linux tools we’re used to,” says Google Research.
The first ISO release of ArchStrike Linux distribution comes as a great news for ethical hackers and security researchers. If you are finding the new ArchStrike unfamiliar, let me tell you that it was previously called ArchAssault.
As the name suggests, ArchStrike Linux distro is based on the highly customizable and lightweight Arch Linux distro.
Now, the ArchStrike developers have announced that ISO images have been made available for download as the official installation medium. So, if you are willing to try out the latest ArchStrike Linux distro for hackers, you can go ahead and download ArchStrike 2016.07.21 ISOs for 64-bit and 32-bit CPUs.
