An open source fix leads to a new career in IT

Filed under
OSS

Today at InterWorx, I write software for Linux for web hosting companies. I got my RHCSA last year, and I'm currently studying for the RHCE. I'd love to say that I got into open source and Linux for philosophical reasons, but to be honest it was just because it let me get stuff done. If it wasn't for Linux and other open source software, I never would have been able to fix that problem all those years ago. With that one opportunity (and a lot of work!), I was able to start a path to a whole new career.

4 open source tools for Linux system monitoring

Filed under
OSS

This article discusses some of the interactive command line interface (CLI) tools that are provided with or which can be easily installed on Red Hat related distributions including Red Hat Enterprise Linux, Fedora, CentOS, and other derivative distributions. Although there are GUI tools available and they offer good information, the CLI tools provide all of the same information and they are always usable because many servers do not have a GUI interface but all Linux systems have a command line interface.

This article concentrates on the tools that I typically use. If I did not cover your favorite tool, please forgive me and let us all know what tools you use and why in the comments section.

  • a lambda is not (necessarily) a closure

    But if you said "it's a closure" -- well you're right in general I guess, like on a semantic what-does-it-mean level, but as far as how Guile represents this thing at run-time, hoo boy are there a number of possibilities, and a closure is just one of them. This article dives into the possibilities, with the goal being to help you update your mental model of "how much do things cost".

    In Guile, a lambda expression can be one of the following things at run-time:

    Gone

    Inlined

    Contified

    Code pointer

    Closure

    Let's look into these one-by-one.

Apache Spark rises to become most active open source project in big data

Filed under
OSS

A healthy interest is not a surprise. In Apache Spark's relatively short life, there's been much discussion of its ascendancy. In September, Databricks, the company behind Spark, released results from a survey showing that Spark is the most active open source project in big data with more than 600 contributors within the past year, which is up from 315 in 2014. Plus, Spark is in use not just in the IT industry, but areas like finance, retail, advertising, education, health care, and more. That survey also showed that 51% of Spark users are using three or more Spark components.

Wandboard.org launched a sandwich-style “HobbitBoard” that runs Brillo on an i.MX6 UltraLite, and offers Intel Edison, Wandboard, and MikroBus expansion.

The HobbitBoard, which is available for pre-order at $69 for March shipment, is the first hacker board to come out of Wandboard.org since the original i.MX6-based Wandboard debuted back in 2012. The Wandboard, which stepped up to a quad-core version in 2013, was one of the very first community-backed, open spec boards following the BeagleBoard. It came out about the same time as the original Raspberry Pi Model B.

  • Open Source and .NET — Why It's Not Picking Up

    Open-source in .NET is not picking up. Despite good efforts from many good people and companies, it seems as if the Microsoft developers scene is far from embracing open-source. Why is this happening, and is there still hope for change?

    [...]

    But, this doesn't seem to be enough. OSS projects in .NET are not striving; there is not much innovation happening in this space; and OSS communities aren't being formed. It is all left as a dream we keep dreaming, but never actually getting to fulfil.

  • LLVM Clang 3.8 Compiler Optimization Benchmarks With -Ofast

    A few days ago I posted a number of LLVM Clang optimization level benchmarks using the latest code for the upcoming Clang 3.8 release. Those tests went from -O0 to -O3 -march=native, but many Phoronix readers wanted -Ofast so here are those results too.

    I didn't include -Ofast in the original tests since I don't know of many using this optimization level within a production capacity considering it has the potential of doing unsafe math as it disregards standards compliance in the name of performance. However, since several readers requested it and I still had this LLVM/Clang 3.8 build around in the same system configuration, I added in extra runs with -Ofast and -Ofast -march=native.

Why I fought for open source in the Air Force

Filed under
OSS

I wanted an open source solution and faced a fair amount of resistance from our lawyers, management, users, and proprietary vendors. It was a difficult struggle at times, and it wasn't until the DoD published their first official guidance on the use of open source software that we started to gain traction. Finally, in the middle of all of the drama, the DoD leadership issued a policy update explicitly stating that open source software was acceptable as long as there was support for it, and that the support could come in the form of government programmers, if necessary.

This memo was a game changer, but it took more than just a policy update to get momentum to shift toward open source.

  • Because You Don’t Need Eyes To Have A Vision

By the time you finish reading this article about Ali and his works, I am sure you would agree with his nickname ‘miracle’.

    Big Data gets a lot of headlines. If any technology can be called heavily hyped, Big Data earns the prize for most breathless predictions of enterprise influence.

  • Hadoop vs. Spark: The New Age of Big Data

    A direct comparison of Hadoop and Spark is difficult because they do many of the same things, but are also non-overlapping in some areas.

    For example, Spark has no file management and therefor must rely on Hadoop’s Distributed File System (HDFS) or some other solution. It is wiser to compare Hadoop MapReduce to Spark, because they’re more comparable as data processing engines.

    Brushless motors are everywhere now. From RC planes to CNC machines, if you need a lot of power to spin something really fast, you’re probably going to use a brushless motor.

He’s been working on this project for a while, and he’s polishing the design to implement a very cool feature – position control.

    For the last five months, The Document Foundation has made use of OSS-Fuzz, Google’s effort to make open source software more secure and stable, to further improve the quality and reliability of LibreOffice’s source code. Developers have used the continuous and automated fuzzing process, which often catches issues just hours after they appear in the upstream code repository, to solve bugs – and potential security issues – before the next binary release.LibreOffice is the first free office suite in the marketplace to leverage Google’s OSS-Fuzz. The service, which is associated with other source code scanning tools such as Coverity, has been integrated into LibreOffice’s security processes – under Red Hat’s leadership – to significantly improve the quality of the source code.

Security Leftovers: HackerOne, Let's Encrypt, and Shadow Brokers

  • Who Are the Shadow Brokers?
    In 2013, a mysterious group of hackers that calls itself the Shadow Brokers stole a few disks full of National Security Agency secrets. Since last summer, they’ve been dumping these secrets on the internet. They have publicly embarrassed the NSA and damaged its intelligence-gathering capabilities, while at the same time have put sophisticated cyberweapons in the hands of anyone who wants them. They have exposed major vulnerabilities in Cisco routers, Microsoft Windows, and Linux mail servers, forcing those companies and their customers to scramble. And they gave the authors of the WannaCry ransomware the exploit they needed to infect hundreds of thousands of computer worldwide this month. After the WannaCry outbreak, the Shadow Brokers threatened to release more NSA secrets every month, giving cybercriminals and other governments worldwide even more exploits and hacking tools.
