Why Security Distributions Use Debian

Filed under

What do distributions like Qube OS, Subgraph, Tails, and Whonix have in common? Besides an emphasis on security and privacy, all of them are Debian derivatives -- and, probably, this common origin is not accidental.

At first, this trend seems curious. After all, other distributions ranging from Slackware and Gentoo to Arch Linux all emphasize security and privacy in their selection of tools. In particular, Fedora's SE Linux can be so restrictive that some users would rather disable it than learn how to configure it. By contrast, while Debian carries many standard security and privacy tools, it has seldom emphasized them.

Similarly, Debian's main branch consists of only free and open source software, its contrib and non-free branches not being official parts of the distribution. With many security experts favoring the announcement of vulnerabilities and exploit code rather than relying on security through obscurity, the way that many pieces of proprietary software do, this transparency has obvious appeal.

Yet although the advantage of free software to security and privacy is that the code can be examined for backdoors and malware, this advantage is hardly unique to Debian. To one or degree another, it is shared by all Linux distributions.

How to incorporate open source into computer science classes

Filed under

This year at the Grace Hopper Conference I'm moderating a panel on why, and how, to incorporate open source into computer science classes. The panelists are four computer science instructors—all women—who have already used open source projects in their classrooms.

I've asked these four talented instructors to tell you a little about themselves, what teaching open source has meant for them and their students, and what you'll hear at the Grace Hopper Celebration of Women in Computing, which is the world's largest gathering of women technologists. This year the event is at the George R. Brown Convention Center in Houston, Texas from October 19-21.

Systemd – Progress Through Complexity

Filed under

A play on the Audi slogan: Vorsprung Durch Technik. Except we’re going to talk about something that is clearly not progress. Systemd. Roughly 6 years ago, Systemd came to life as the new, event-based init mechanism, designed to replicate the old serialized System V thingie. Today, it is the reality in most distributions, for better or worse. Mostly the latter.

Why would you oppose progress, one may say. To that end, we need to define progress. It is merely the state of something being newer, AKA newer is always better, or the fact it offers superior functionality that was missing in the old technology? After all, System V is 33 years old, so the new stuff ought to be smarter. The topic of my article today is to tell you a story of how I went about fixing a broken Fedora 24 system – powered by systemd of course, and why, at the end of, my conclusion was one of pain and defeat.

Tiny OpenWRT WiFi module updated in $12 and $4 versions

Filed under

The $12 “VoCore2” WiFi COM, which runs OpenWrt on a Mediatek MT7688AN, has won Indiegogo funding and has been joined by a $4 “VoCore2 Lite” version.

Back in 2014, we hailed the $20 VoCore computer-on-module as the smallest yet to run Linux, measuring only 25 x 25mm. Earlier this month, China-based VoCore launched an updated open source VoCore2 board on Indiegogo, and quickly surpassed its modest flexible funding goal. With a month left, the campaign decided to fulfill an informal stretch goal based on popular demand to produce a cheaper version.

3 Twitter clients for the Linux command line

Filed under

While this may seem like a solution searching for a problem, for some people interacting with Twitter in a terminal window makes sense. There's less distraction at the command line than with a desktop Twitter client or even Twitter's web interface. On top of that, command-line clients are fast and their interfaces are generally quite clean.

No matter why you want to work with Twitter in a terminal, there are applications out there for you. Here's a look at three Twitter clients that you can run from the command line.

‘Why Use Linux?’ Answered In 3 Short Words

Filed under

This post is not a typical post. I’m not going to change your life, or teach you a new trick. Instead I’m going to drag you down the rabbit hole…

I had to Google a rather dry grammatical enquiry from my sister earlier. See, she’s in the process of going back to college to study nursing and has become fastidious about punctuation in the process.

She turned to me because her iPhone did not, in her words, ‘give the correct answer’.

Leftovers: KDE


  • 4 Useful Cinnamon Desktop Applets
    The Cinnamon desktop environment is incredibly popular, and for good reason. Out of the box it offers a clean, fast and well configured desktop experience. But that doesn’t mean that you can’t make it a little better with a few nifty extras. And that’s where Cinnamon Applets come in. Like Unity’s Indicator Applets and GNOME Extensions, Cinnamon Applets let you add additional functionality to your desktop quickly and easily.
  • GNOME Core Apps Hackfest
    The hackfest is aimed to raise the standard of the overall core experience in GNOME, this includes the core apps like Documents, Files, Music, Photos and Videos, etc. In particular, we want to identify missing features and sore points that needs to be addressed and the interaction between apps and the desktop. Making the core apps push beyond the limits of the framework and making them excellent will not only be helpful for the GNOME desktop experience, but also for 3rd party apps, where we will implement what they are missing and also serve as an example of what an app could be.
  • This Week in GTK+ – 21

So here it is, with the first five reasons in this article and the others to follow. As a quick introduction, Kubernetes is "an open-source system for automating deployment, scaling and management of containerized applications" often referred to as a container orchestrator.
  • Website-blocking attack used open-source software
    Mirai gained notoriety after the Krebs attack because of the bandwidth it was able to generate — a record at well over 600 gigabits a second, enough to send the English text of Wikipedia three times in two seconds. Two weeks later, the source code for Mirai was posted online for free.
  • Alibaba’s Blockchain Email Repository Gains Technology from Chinese Open Source Startup
    Onchain, an open-source blockchain based in Shanghai, will provide technology for Alibaba’s first blockchain supported email evidence repository.

Its consortium chain product, the Law Chain, will provide technology for Ali Cloud, Alibaba’s computing branch. Ali Cloud has integrated Onchain’s Antshares blockchain technology to provide an enterprise-grade email repository. Onchain provides the bottom-layer framework for Ali Cloud, including its open-source blockchain capabilities, to enable any company to customize its own enterprise-level blockchain.
  • Netflix on Firefox for Linux
    If you're a Firefox user and you're a little fed up with going to Google Chrome every time in order to watch Netflix on your Linux machine, the good news is since Firefox 49 landed, HTML5 DRM (through the Google Widevine CDM (Content Decryption Manager) plugin) is now supported. Services that use DRM for HTML5 media should now just work, such as Amazon Prime Video. Unfortunately, the Netflix crew haven't 'flicked a switch' yet behind the scenes for Firefox on Linux, meaning if you run Netflix in the Mozilla browser at the moment, you'll likely just come across the old Silverlight error page. But there is a workaround. For some reason, Netflix still expects Silverlight when it detects the user is running Firefox, despite the fact that the latest Firefox builds for Linux now support the HTML5 DRM plugin.

    Public policy makers in Sweden have limited insight on how IT project can lead to IT vendor lock-in, a study conducted for the Swedish Competition Authority shows. “An overwhelming majority of the IT projects conducted by schools and public sector organisations refer to specific software without considering lock-in and different possible negative consequences”, the authors conclude.
  • How open access content helps fuel growth in Indian-language Wikipedias
    Mobile Internet connectivity is growing rapidly in rural India, and because most Internet users are more comfortable in their native languages, websites producing content in Indian languages are going to drive this growth. In a country like India in which only a handful of journals are available in Indian languages, open access to research and educational resources is hugely important for populating content for the various Indian language Wikipedias.
  • Where to find the world's best programmers
    One source of data about programmers' skills is HackerRank, a company that poses programming challenges to a community of more than a million coders and also offers recruitment services to businesses. Using information about how successful coders from different countries are at solving problems across a wide range of domains (such as "algorithms" or "data structures" or specific languages such as C++ or Java), HackerRank's data suggests that, overall, the best developers come from China, followed closely by Russia. Alarmingly, and perhaps unexpectedly, the United States comes in at 28th place.

  • AtScale Delivers Findings on BI-Plus-Hadoop
    Business intelligence is the dominant use-case for IT organizations implementing Hadoop, according to a report from the folks at AtScale. The benchmark study also shows which tools in the Haddop ecosystem are best for particular types of BI queries. As we've reported before, tools that demystify and function as useful front-ends and connectors for the open source Hadoop project are much in demand. AtScale, billed as “the first company to allow business users to do business intelligence on Hadoop,” focused its study on the strengths and weaknesses of the industry’s most popular analytical engines for Hadoop – Impala, SparkSQL, Hive and Presto.
  • Study Says OpenStack at Scale Can Produce Surprising Savings
    Revenues from OpenStack-based businesses are poised to grow by 35 percent a year to more than $5 billion by 2020, according to analysts at 451 Research. In its latest Cloud Price Index, 451 Research analyzes the costs associated with using various cloud options to determine when it becomes better value to use a self-managed private cloud instead of public or managed cloud services. The idea is to createa complex pricing model that takes into consideration the major factors impacting total cost of ownership (TCO), including salaries and workload requirements.The 451 study found that because of the prevalence of suitably qualified administrators, commercial private cloud offerings such as VMware and Microsoft currently offer a lower TCO when labor efficiency is below 400 virtual machines managed per engineer. But where labor efficiency is greater than this, OpenStack becomes more financially attractive. In fact, past this tipping point, all private cloud options are cheaper than both public cloud and managed private cloud options.
  • How OpenStack mentoring breaks down cultural barriers
    Victoria Martinez de la Cruz is no stranger to OpenStack's mentorship opportunities. It's how she got her own start in OpenStack, and now a few years later is helping to coordinate many of these opportunities herself. She is speaking on a panel on mentoring and internships later this week at OpenStack Summit in Barcelona, Spain. In this interview, we catch up with Victoria to learn more about the details of what it's like to be a part of an open source internship, as well as some helpful advice for people on both sides of the mentoring process.
