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.
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.
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.
Some good news! SWORDY has been given the green light to come to Linux & SteamOS by Microsoft, as the developer was a bit confused due to the Xbox One exclusive deal they have.
Not only is our first 4.0.0 alpha release here – but it is here relatively on schedule. If all goes according to plan we will have something stamped as stable before September hits. I would just like to be clear that this is far from a polished / finished product. I would encourage anyone wanting to write a review to wait to do so until our stable release. If you are not someone who is interested in helping find issues please wait as well.
It's no secret that Chrome OS has not been the same striking success for Google that the Android OS has been. And yet, Chromebooks--portable computers running the platform--have not only found their niche, but they are also introducing a new generation to cloud computing. Chromebooks are firmly entrenched in the education market, where many young users have become used to the convention of storing apps and data in the cloud.
Now, according to new research from Gartner, Chromebooks are ready to hit new milestones. Analysts there report that Chromebook shipment growth will be in the double digits this year. At the same time, though, Chromebooks have not become fixtures in the enterprise, replacing Windows PCs.
Alexandre Oliva from the GNU Linux-libre project happily announced the release and general availability for download of the GNU Linux-libre 4.7 kernel for those who want 100% freedom when using a GNU/Linux operating system.
The release of GNU Linux-libre kernel 4.7 comes a few hours after Linus Torvalds' announcement for the new Linux 4.7 kernel branch, on which GNU Linux-libre 4.7-gnu is based, and, as usual, it contains deblobbing changes for various of the included drivers, including Radeon, Intel i915 CSR, Intel Skylake audio, HFI1 InfiniBand, Realtek rtl8xxxu Wi-Fi, iwlwifi, mwifiex, Broadcom brcmfmac, and Atheros ath10k.
