The People Who Support Linux: Systems Engineer Teaching Himself Python

Filed under
GNU
Linux

Systems engineer Renault Ellis started using Linux five years ago when he was enrolled in a security and forensics program. He was studying IP tables and read the C Programming Language manual by Ken Thompson and Dennis Ritchie along with Cliff Stoll’s The Cuckoo’s Egg.

“I was hooked,” Ellis said via email. “I knew then I wanted to be a Linux Engineer.”

Ellis is now a Senior Linux and Unix Engineer at electronics distributor Premier Farnell in Chicago, Illinois, where he creates, tests and deploys scripts in an eCommerce environment. He works with Apache and several different monitoring tools, both open source and commercial, and leads a lot of the DR (disaster recovery) and PCI (payment card industry) processes in their Unix environment.

Linux
Ubuntu

During the Big Buck Bunny video playback process, the CPU usage was monitored by the test profile and we also monitored each graphics card's GPU temperature, GPU usage, and the overall AC system power draw (via a WattsUp power meter). The additional sensors can be polled automatically by the Phoronix Test Suite by setting the MONITOR=gpu.usage,gpu.temp,sys.power environment variable. This testing is quite straight forward and mainly intended for reference purposes for those thinking about a NVIDIA GPU for a Linux HTPC / multimedia PC, so let's get straight to the data.

Makulu Linux 6.0 KDE: Guaranteed to make you smile

Filed under

Linux
Reviews

Another Makulu Linux distribution was released today, and that's always good news! This time it is the KDE desktop for the Makulu 6.x series. The Xfce version of this was just released a couple of weeks ago, so i don't exptect for there to be any major surprised: I hope that means this will not be a very lengthy post.

As usual, the release announcement gives a good overview of the what and why in this release. The most important specifics are that it is built on Linux kernel 3.14.7 and KDE SC 4.13.1. The download images are available from the Makulu Linux KDE page, it is a 32-bit (i686) build that is approximately 1.7GB in size. It is a hybrid ISO, so you can burn it to disk or dump it with dd to a USB stick, and it does not support UEFI boot.

At the invitation only Linux Enterprise End-User Summit held at the Convene Center Financial District, Jim Zemlin, the Linux Foundation's executive director, told an audience of several hundred Wall Street executives and top Linux developers what he sees as the future of technology.

If the combination of Wall Street bears and bulls and Linux programmers seems odd, then you haven't been paying attention. The New York Stock Exchange, New York Mercantile Exchange, and NASDAQ all run on Linux. Indeed, almost all stock exchanges now rely on Linux.

Zorin OS 9 RC Is Now the Perfect Replacement for Windows 7 and Windows XP

Filed under
Linux
Microsoft
Ubuntu

There are quite a few Linux distributions that take direct aim at the Windows users, but not all of them are as appreciated as Zorin OS. The developers have managed to release a fresh take on the old desktop paradigm used by Windows. It somewhat resembles that well-known interface, but it manages to also feel new.

This latest edition is still in the development stages and it will take a while until it is ready, but, from the looks of it, Zorin OS 9 RC is already a winner. It's now based on Ubuntu 14.04 LTS (Trusty Tahr), which was released a couple of months ago, meaning that it will also come with extended support.

Leftovers: OSS

  • Diving into Drupal: Princeton’s Multi-site Migration Success with Open-source
    Princeton University’s web team had a complex and overwhelming digital ecosystem comprised of many different websites, created from pre-built templates and hosted exclusively on internal servers. Fast forward six years: Princeton continues to manage a their multisite and flagship endeavors on the open-source Drupal platform, and have seen some great results since their migration back in 2011. However, this success did not come overnight. Organizational buy-in, multi-site migration and authentication were a few of the many challenges Princeton ran into when making the decision to move to the cloud.
  • GitHub Invites Developers to Contribute to the Open Source Guides
    GitHub has recently launched its Open Source Guides, a collection of resources addressing the most common scenarios and best practices for both contributors and maintainers of open source projects. The guides themselves are open source and GitHub is actively inviting developers to participate and share their stories.
  • Top open source projects
    TechRadar recently posted an article about "The best open source software 2017" where they list a few of their favorite open source software projects. It's really hard for an open source software project to become popular if it has poor usability—so I thought I'd add a few quick comments of my own about each.
  • Dropbox releases open-source Slack bot
    Dropbox is looking to tackle unauthorized access and other security incidents in the workplace with a chatbot. Called Securitybot, it that can automatically grab alerts from security monitoring tools and verify incidents with other employers. The company says that through the use of the chatbot, which is open source, it will no longer be necessary to manually reach out to employees to verify access, every time someone enters a sensitive part of the system. The bot is built primarily for Slack, but it is designed to be transferable to other platforms as well.
  • Dropbox’s tool shows how chatbots could be future of cybersecurity
    Disillusion with chatbots has set in across the tech industry and yet Dropbox’s deep thinkers believe they have spotted the technology’s hidden talent: cybersecurity.

  • Freedom From Microsoft v1.01
    But we can be Free from Microsoft! As we saw above, there is a powerful – and now popular movement afoot to make alternative software available. The Free Software Foundation, and the GNU Project, both founded by Richard Stallman, provide Free software to users with licenses that guarantee users rights: the rights to view, modify, and distribute the software source code. With GNU-licensed software, such as Linux, the user is in complete control over the software they employ. And as people contribute to modify Free Software source code, and are required to share those modifications again, the aggregate creative acts give rise to the availability of many more, much more useful results. Value is created beyond what anyone thought possible, and our freedom multiplies.
  • Review of the week 2017/08
    This week we had to cancel a couple snapshots, as a regression in grub was detected, that caused issues on chain-loading bootloaders. But thanks to our genius maintainers, the issue could be found, fixed and integrated into Tumbleweed (and this despite being busy with hackweek! A great THANK YOU!). Despite those canceled snapshots, this review will still span 4 revisions: 0216, 0218, 0219 and 0224. And believe me, there have been quite some things coming your way.

Security Leftovers

  • [Older] The Secure Linux OS - Tails
    Some people worry a lot about security issues. Anyone can worry about their personal information, such as credit card numbers, on the Internet. They can also be concerned with someone monitoring their activity on the Internet, such as the websites they visit. To help ease these frustrations about the Internet anyone can use the Internet without having to “look over their shoulder”.
  • Password management made easy as news of CloudFlare leak surfaces
    In the last 24 hours, news broke that a serious Cloudflare bug has been causing sensitive data leaks since September, exposing 5.5 million users across thousands of websites. In addition to login data cached by Google and other search engines, it is possible that some iOS applications have been affected as well. With the scale of this leak, the best course of action is to update every password for every site you have an account for. If there was ever a good time to modernize your password practices, this is it. As consumers and denizens of the Internet, we have a responsibility to be aware of the risks we face and make an attempt to mitigate that risk by taking best-effort precautions. Poor password and authentication hygiene leaves a user open to risks such as credit card fraud and identity theft, just like forgetting to brush your teeth regularly can lead to cavities and gum disease. This leaves us with the question of what good password and authentication hygiene looks like. If we stick with the (admittedly poorly chosen) dentistry analogy, then there are five easily identifiable aspects of good hygiene.
  • Security: You might want to change passwords on sites that use Cloudflare
  • Smoothwall Express
    The award-winning Smoothwall Express open-source firewall—designed specifically to be installed and administered by non-experts—continues its forward development march with a new 3.1 release.

Leftovers: Ubuntu and Derivatives

  • 'Big Bang Theory's' Stuart wears Ubuntu T-shirt
    Am I the only person to notice that comic book shop-owning Stuart (Kevin Sussman) on the "The Big Bang Theory" is wearing an Ubuntu T-shirt on the episode airing Thursday, Feb. 23, 2017? (It's Season 10, Episode 17, if that information helps you.) The T-shirt appearance isn't as overt as Sheldon's mention of the Ubuntu Linux operating system way back in Season 3 (Episode 22, according to one YouTube video title), but it's an unusual return for Ubuntu to the world of "Big Bang."
  • Unity Explained: A Look at Ubuntu’s Default Desktop Environment
    Ubuntu is the most well-known version of Linux around. It’s how millions of people have discovered Linux for the first time, and continues to draw new users into the world of open source operating systems. So the interface Ubuntu uses is one many people are going to see. In this area, Ubuntu is unique. Even as a new user, rarely will you confuse the default Ubuntu desktop for something else. That’s because Ubuntu has its own interface that you can — but probably won’t — find anywhere else. It’s called Unity.
  • A Look at Ubuntu MATE 16.04.2 LTS for Raspberry Pi
    Installing Ubuntu MATE onto my Raspberry Pi 3 was straight forward. You can easily use Etcher to write the image to a microSD card, the partition is automatically resized to fill your microSD card when the pi is powered up for the first time, and then you are sent through a typical guided installer. Installation takes several minutes and finally the system reboots and you arrive at the desktop. A Welcome app provides some good information on Ubuntu MATE, including a section specific for the Raspberry Pi. The Welcome app explains that the while the system is based on Ubuntu MATE and uses Ubuntu armhf base, it is in fact using the same kernel as Raspian. It also turns out that a whole set of Raspian software has been ported over such as raspi-config, rpi.gpio, sonic-pi, python-sent-hat, omxplayer, etc. I got in a very simple couple of tests that showed that GPIO control worked.
