The Linux Foundation’s New Training Bundle to Increase Career Mobility for SysAdmins

New course and certification bundle to accelerate opportunities for
advanced Linux learning among career technologists

SAN FRANCISCO, May 12, 2016 – The Linux Foundation, the nonprofit advancing professional open source management for mass collaboration, today announced the availability of its new course, LFS211 Advanced Linux System Administration and Networking. The course provides the knowledge and skills necessary to succeed as a senior Linux sysadmin, as well as to pass the Linux Foundation Certified Engineer (LFCE) exam, which comes bundled with the new course.

The 2016 Open Source Jobs Report, produced by The Linux Foundation and Dice, finds that 51 percent of hiring managers say hiring certified professionals is a priority for them, and 47 percent of open source professionals plan to take at least one certification exam this year. Certifications are increasingly becoming the best way for professionals to differentiate from other job candidates and to demonstrate their ability to perform critical technical functions.

“More individuals and more employers are seeing the tremendous value in certifications, but it can be time-consuming and cost-prohibitive to prepare for them,” said Linux Foundation General Manager for Training Clyde Seepersad. “The Linux Foundation strives to increase accessibility to quality training and certification for anyone, and offering advanced system administration training and certification that can be accessed anytime, anywhere, for a lower price than the industry standard helps to achieve that.”

With the tremendous growth in open source adoption across technology sectors, it is more important than ever for IT professionals to be proficient in Linux. With the recent embrace by Microsoft of Linux on Azure, every major cloud platform is now based on or, as is the case for Azure, runs Linux. Similarly, OpenStack - one of the leading cloud platforms, for which The Linux Foundation also offers a course to prepare for the new Certified OpenStack Administrator exam - is deployed on Linux. Sysadmins of all stripes today need to be familiar with Linux, and the type of training provided by this course confers the knowledge and skills necessary to manage these systems.

LFS211 serves as preparation for the advanced LFCE exam in the way LFS201 Essentials of System Administration serves as preparation for the Linux Foundation Certified SysAdmin (LFCS) exam. Students in the new course will have access to 40-50 hours of coursework, and over 50 hands-on labs, which includes practical experience that translates to real-world situations. Becoming LFCE certified provides individuals who are more established or advanced in their IT careers the opportunity to progress further and demonstrate their knowledge. Sysadmins who pass the LFCE exam have a wider range and greater depth of skill than the LFCS. Linux Foundation Certified Engineers are responsible for the design and implementation of system architecture and serve as subject matter experts and mentors for the next generation of system administration professionals.

Individuals interested in registering for LFS211 can do so at http://go.linuxfoundation.org/rd-lfs211-launch-pr for the introductory price of $349, including access to the course material for one year, and a voucher to take the LFCE exam up to two times. For more information on Linux Foundation training and certification programs, visit http://training.linuxfoundation.org.

Hope I've shared this in the right place. For Sysadmins out there this is a very useful list of Server and APM monitoring solutions. With the help of the community, it has grown to include just about every solution worth your time.

Not more than a list of vendor and product names with generic product descriptions that are of no use whatsoever. If you have decades of knowledge with some of them, I wonder why there is not event a hint of useful information about the usage scenarios and capabilities?

With the Raspberry Pi 3 already being much faster than its predecessors. For a performance boost I've simply been using:

force_turbo=1
boot_delay=1

* force_turbo=1 Voids Warranty. boot_delay=1 helps to avoid sdcard corruption when force_turbo is enabled.

It's that time again. You may remember my old overclocking post for Raspberry Pi and the Raspberry Pi 2. Yes, still obsessed with performance. So this post

With the Raspberry Pi 2 there’s a host of options to choose from for the required accessories needed to get started. Just basics like power, wifi and storage. I’ve spent months of research and testing to ensure that I don’t waste time having to replace accessories till I find the best ones.

We have to put thought into powering this board device, interfacing with it, protecting the board, wireless network connectivity, microSD storage, etc. Over the past 2 years I’ve been playing with various Raspberry Pi models and like most, I’m really impressed which how much faster and still stable the Raspberry Pi 2 is. That said the Raspberry Pi remains vulnerable to poor customer satisfaction if paired with cheap or not fully compatible accessories. You can spend hours trying to solve freezing, reset, data corruption and other issues which at some point you’ll find rarely have anything to do with the actual RPI 2 board.
 
As with any consumer device that’s become popular, there have been a flood of options to choose from! Today we focus on the three most important addons: power adapter, MicroSD storage and WiFi connectivity. This post aims at guiding readers to the best options available which I’ve tested and personally use without issue. Getting these options right, can save you time, money and much headache. So without any further delay, here are my recommended picks for my ultimate Raspberry Pi 2 starter kit!

Power Supply: CanaKit 5V 2.5A for Raspberry Pi 2 Adapter

The CanaKit 2.5A Raspberry Pi 2 power supply/adapter has been specially designed and tested for the new Raspberry Pi 2. With this power supply, you can power the Raspberry Pi 2 at full loads. It’s also great for over-clocking the Raspberry Pi which lower powered/quality adapters usually causes freezes or resets. This power supply differs from typical 5V USB power supplies because it can deliver a full 2.5A and still output a voltage well within the minimum voltage specifications for the Raspberry Pi board. Many of the 5V USB power supplies in the market suffer voltage drops when pushed which may cause the Raspberry Pi to reboot or freeze unexpectedly.

MicroSD Card: Transcend 16GB MicroSDHC Class10 UHS-1 with SD Adapter 45MB/s

Transcend’s microSDHC/SDXC Class 10 UHS-I 300X memory cards can realize blazing-fast read/write transfer rates of up to 300x (45MB/s). Built-in Error Correcting Code (ECC) to detect and correct transfer errors. Supports Ultra High Speed Class 1 specification (U1). Fully compliant with the SD 3.01 standard. Available in 16GB (TS16GUSDU1), 32GB (TS32GUSDU1) and 64GB (TS64GUSDU1) capacities. Highly recommended option stability, value and speed!

Also check out the x2 faster Transcend MicroSDHC Class 10 UHS-I Memory cards with Adapter 90 Mb/s. Available in 16GB (TS16GUSDHC10U1) and 32GB (TS32GUSDHC10U1). Highly recommended for read/write intensive uses such as Kodi (OpenElec, OSMC, etc.) These are fast, yet stable at a slightly higher cost.

WiFi: Panda 300Mbps Wireless 802.11n USB Adapter with high gain antenna (PAU06)

The Panda 300Mbps Wireless 802.11n USB Adapter with high gain antenna (PAU06) with low power consumption. OS support includes: 32-bit and 64-bit Windows XP/ Vista/ 7/ 8/ 8.1/10/2008r2/2012r2, Mint 14/15/16/17/17.1, Ubuntu 12.10/13.04/13.10/14.04/14.10, Fedora 18/19/20/21, CentOS 6.4/6.5/7. 

Looking for basic connectivity and not worried about range and speed? Then check out the TP-LINK TL-WN725N Wireless N Nano USB Adapter 150Mbps. Also look at the size of this thing! Don’t lose it.
 
Other Raspberry Pi starter recommendations:

Raspberry Pi protective case. Official Raspberry Pi Foundation Pi 2 Case.
Mini Wireless Keyboard/Touchpad: Rii Mini 2.4G Wireless Backlight Keyboard with Mouse Touchpad Laser Pointer.
The HDMI cables I currently use: Zakix® 6 FT, Premium High-Speed & Certified HDMI 2.0 Cable – 6 Feet.

Sorry but Archlinux doesn't officially support the ARM processor so Arch Linux ARM is a derivative and goes against our rules. There is a nice Arch Linux ARM community on G+ for these posts.
https://plus.google.com/u/0/communities/105474354290825268509

"2. Shares containing information about Arch Linux Derivatives including but not limited to Antergos and Archbang will be deleted if they do not contain information directly relative to Vanilla Arch Linux and its repositories[1]."

When Archlinux.org supports the ARM processor, so shall we.
