  • Call for papers

    BSDCan is an enormously successful grass-roots style conference. It brings together a great mix of *BSD developers and users for a nice blend of both developer-centric and user-centric presentations, food, and activities.

  • Screenshots from developers: 2002 vs. 2015

    In 2002 I asked a number of developers/Unix people for screenshots of their desktops. I recently republished them, and, seeing the interest this generated, I thought it’d be fun to ask the same people* again 13 years later. To my delight I managed to reach many of them.

  • PC-BSD 11.0-Current Images Ready, and Let’s Read Some Mail

    Parsing the developments from the BSD side of things this week for consumption by the general public is a little trickier than it is across the street on the Linux side, however with a little juggling (and an important note from iXsystems to come tomorrow in the weekly FOSS roundup), we’ll take a look at the new images ready for your testing and feedback. Also, I’ll answer some questions which arose in last week’s comments.

Guarding the gates with OpenBSD 5.8

Filed under
Reviews
BSD

The OpenBSD project has long held a reputation for producing a secure operating system. The project boasts just two remote security holes reported over a span of about twenty years. It's an impressive accomplishment for the developers and a good indication of why OpenBSD is so often trusted for security oriented tasks like running firewalls. However, the OpenBSD team has been steadily working on other projects too. The team behind OpenBSD also creates the widely used OpenSSH software which is used around the world by system administrators to remotely work on servers and securely transfer files. The OpenBSD project also spawned the LibreSSL software (a replacement for OpenSSL) following the Heartbleed vulnerability. In the latest release of OpenBSD we also saw improvements to the project's lightweight and secure web server (called httpd), the introduction of the doas command (a replace for sudo), a new implementation of the file command and W^X support for i386 processors. The latest version of the operating system, OpenBSD 5.8, also switched to denying root logins in the default installation.

BSD

DragonFly version 4.4 bring further updates to accelerated video for both i915 and radeon users, a new locale system, and a new default linker. Significant behind-the-scenes work has also been done, with symbol versioning, Hammer1 improvements, and other changes. Version 4.4.1 was the first release due to the late inclusion of OpenSSL update 1.0.1q.

BSD for the desktop user: A review of PC-BSD

Filed under
Reviews
BSD

To be clear, the BSDs are not Linux distributions. They are Unix-like, so they are similar to Linux, but they are their own family of open source operating systems with their own rich history. Unlike Linux with its multitude of distributions, the BSD family is much smaller; the big three distributions are FreeBSD, NetBSD, and OpenBSD. The small handful of other BSD distributions branch off from one of those projects, most frequency, from FreeBSD.

DragonFlyBSD 4.4 Brings Collation Support, Uses Gold Linker By Default

Filed under
BSD

DragonFlyBSD 4.4 is ready for release with a number of exciting improvements and new features.

DragonFlyBSD 4.4 delivers improvements to the i915 and Radeon DRM drivers that are now up to parity with their state from Linux 3.18, supports collation for named locales, a overhauled locale system, and the regex library was replaced with the TRE library. Also very prominent to DragonFlyBSD 4.4 is that it uses the Gold linker by default.

A few thoughts on OpenBSD 5.8

Filed under
BSD

I've been using OpenBSD since way back at release 2.3 in 1998, so I've gone through upgrades that took a fair amount of work due to incompatible changes, like the switch from ipf to pf for host firewalling or the change to ELF binaries. The upgrade from 5.7 to 5.8 was a pretty smooth and easy one, for the most part. The two most painful changes for me were the replacement of sudo with doas and the dropping of support in the rc.conf for the pf_rules variable. While sudo is still available as a package, I like the idea of reducing attack surface with a simpler program, so I made the switch. The two things I miss most about sudo are the ability to authenticate for a period of time and the ability to have a single config file across a whole set of servers. The former I'm just living with, the latter I've adjusted to by having a single config file that has lines commented out depending on which server it's on. I did have one moment of concern about the quality of doas when it incorrectly reported the line number on which I had a syntax error in the config file--fortunately, this was just a failure to increment the line count on continuation lines (ending with a "\") which is fixed in the -current release.

Area51 updates (KDE on FreeBSD)

Filed under
KDE
BSD

The area51 repository continues to update, even as the official ports tree for FreeBSD sticks with KDE4. Since the KDE-FreeBSD team is also responsible for the official ports, that basically means that not everything has been shaken out yet, and that the team doesn’t feel that it can provide a really good Frameworks5 / Plasma5 / Applications installation .. yet. I’ve been playing with ideas for a default desktop wallpaper (the upstream default gives me a headache; I’d really like to combine Flying Konqui by Timothée Giet with bubbles made from the BSD logo.

DragonFlyBSD Switches To Gold Linker By Default

Filed under
BSD

DragonFlyBSD has switched to using the Gold Linker by default rather than GNU ld.

The GNU Gold linker for ELF files is designed to be faster and much more modern than the GNU linker. DragonFlyBSD has traditionally used GNU ld, but now Gold is ready for primetime use by default on this BSD distribution.

OpenBSD Interview: Renato Westphal (renato@)

Filed under
Interviews
BSD

My history with OpenBSD started around 2011 when I was still an undergrad student working part-time on an University-Industry partnership program. In this job I was assigned the task of implementing a full (!) MPLS solution for Linux and that task encompassed having a working implementation of the LDP protocol, among several other things. I started then looking for an open source implementation of LDP and found out that OpenBSD had a daemon called ldpd(8). I decided to check it out and it was love at the first sight when I saw its code: it was beautiful! I started then porting this daemon to Linux and on top of that fixed quite a few bugs. Two years later I decided that it would be fair to contribute my fixes back to the original implementation, it was when claudio@ invited me to join the OpenBSD team. Around that time I didn't know much about OpenBSD and was surprised with the invitation. Theo de Raadt sent me a couple of emails and I had no clue about who he was. Nevertheless, I was excited with the invitation and started to follow the mailing lists and even bought a book about OpenBSD. Within a couple days I was hooked on it and OpenBSD became my OS of choice.

  • IOTA: IoT revolutionized with a Ledger
    Ever since the introduction of digital money, the world quickly came to realize how dire and expensive the consequences of centralized systems are. Not only are these systems incredibly expensive to maintain, they are also “single points of failures” which expose a large number of users to unexpected service interruptions, fraudulent activities and vulnerabilities that can be exploited by malicious hackers. Thanks to Blockchain, which was first introduced through Bitcoin in 2009, the clear benefits of a decentralized and “trustless” transactional settlement system became apparent. No longer should expensive trusted third parties be used for handling transactions, instead, the flow of money should be handled in a direct, Peer-to-Peer fashion. This concept of a Blockchain (or more broadly, a distributed ledger) has since then become a global phenomenon attracting billions of dollars in investments to further develop the concept.
  • Return Home and Unify: My Case for Unity 8
  • Can netbooks be cool again?
    Earlier this week, my colleague Chaim Gartenberg covered a laptop called the GPD Pocket, which is currently being funded on Indiegogo. As Chaim pointed out, the Pocket’s main advantage is its size — with a 7-inch screen, the thing is really, really small — and its price, a reasonable $399. But he didn’t mention that the Pocket is the resurrection of one of the most compelling, yet fatally flawed, computing trends of the ‘00s: the netbook. So after ten years, are netbooks finally cool again? That might be putting it too strongly, but I’m willing to hope.

  • Compact, rugged module runs Linux or Android on Apollo Lake
    Ubiqcomm’s 95 x 95mm, Apollo Lake-based “COM-AL6C” COM offers 4K video along with multiple SATA, USB, GbE, and PCIe interfaces, plus -40 to 85°C operation. Ubiqconn Technology Inc. has announced a “COM-AL6C” COM Express Type 6 Compact form factor computer-on-module built around Intel’s Apollo Lake processors and designed to withstand the rigors of both fixed and mobile industrial applications. The module offers a choice among three Intel Apollo Lake processors: the quad-core Atom x5-E3930, quad-core x5-E3940, and dual-core x7-E3950, which are clocked at up to 2.0GHz burst and offer TDPs from 6.5 to 12 Watts.
  • Internet-enable your microcontroller projects for under $6 with ESP8266
    To get started with IoT (the Internet of Things), your device needs, well, an Internet connection. Base Arduino microcontrollers don't have Internet connectivity by default, so you either need to add Ethernet, Wi-Fi shields, or adapters to them, or buy an Arduino that has built-in Internet connectivity. In addition to complexity, both approaches add cost and consume the already-precious Arduino flash RAM for program space, which limits what you can do. Another approach is to use a Raspberry Pi or similar single-board computer that runs a full-blown operating system like Linux. The Raspberry Pi is a solid choice in many IoT use cases, but it is often overkill when all you really want to do is read a sensor and send the reading up to a server in the cloud. Not only does the Raspberry Pi potentially drive up the costs, complexity, and power consumption of your project, but it is running a full operating system that needs to be patched, and it has a much larger attack surface than a simple microcontroller. When it comes to IoT devices and security, simpler is better, so you can spend more time making and less time patching what you already made.

    Every day, we see people building things. Sometimes, useful things. Very rarely, this thing becomes a product, but even then we don’t hear much about the ins and outs of manufacturing a bunch of these things or the economics of actually selling them. This past weekend at Shmoocon, [Conor Patrick] gave the crowd the inside scoop on selling a few hundred two factor authentication tokens. What started as a hobby is now a legitimate business, thanks to good engineering and abusing Amazon’s distribution program.
  • 1.8 Billion Mobile Internet Users NEVER use a PC, 200 Million PC Internet Users never use a mobile phone. Understanding the 3.5 Billion Internet Total Audience
    As I am working to finish the 2017 Edition of the TomiAhonen Almanac (last days now) I always get into various updates of numbers, that remind me 'I gotta tell this story'.. For example the internet user numbers. We have the December count by the ITU for year 2016, that says the world has now 3.5 Billion internet users in total (up from 3.2 Billion at the end of year 2015). So its no 'drama' to know what is 'that' number. The number of current internet total users is yes, 3.5 Billion, almost half of the planet's total population (47%).

  • Rewriting the history of free software and computer graphics
    Do you remember those days in the early nineties when most screensavers were showing flying 3D metallic logotypes? Did you have one? In this article, I want to go back in time and briefly revise the period in the history of computer graphics (CG) development when it transitioned from research labs to everyone's home computer. The early and mid-1990s was the time when Aldus (before Adobe bought the company) was developing PageMaker for desktop publishing, when Pixar created ToyStory, and soon after 3D modeling and animation software Maya by Alias|Wavefront (acquired by Autodesk). It was also a moment when we got two very different models of CG development, one practiced by the Hollywood entertainment industry and one practiced by corporations like Adobe and Autodesk. By recalling this history, I hope to be able to shed new light on the value of free software for CG, such as Blender or Synfig. Maybe we can even re-discover the significance of one implicit freedom in free software: a way for digital artists to establish relations with developers. [...] The significance of free software for CG On the backdrop of this history, free software like Blender, Synfig, Krita, and other projects for CG gain significance for several reasons that stretch beyond the four freedoms that free software gives. First, free software allows the mimicking of the Hollywood industry's models of work while making it accessible for more individuals. It encourages practice-based CG development that can fit individual workflows and handle unexpected circumstances that emerge in the course of work, rather than aiming at a mass product for all situations and users. Catering to an individual's needs and adaptations of the software brings users work closer to craft and makes technology more human. Tools and individual skill can be continuously polished, shaped, and improved based on individual needs, rather than shaped by decisions "from above."

  • [FreeDOS] The readability of DOS applications
    Web pages are mostly black-on-white or dark-gray-on-white, but anyone who has used DOS will remember that most DOS applications were white-on-blue. Sure, the DOS command line was white-on-black, but almost every popular DOS application used white-on-blue. (It wasn't really "white" but we'll get there.) Do an image search for any DOS application from the 1980s and early 1990s, and you're almost guaranteed to yield a forest of white-on-blue images like these:
  • More about DOS colors
    In a followup to my discussion about the readability of DOS applications, I wrote an explanation on the FreeDOS blog about why DOS has sixteen colors. That discussion seemed too detailed to include on my Open Source Software & Usability blog, but it was a good fit for the FreeDOS blog.
  • Building a $4 billion company around open source software: The Cloudera story
    Dr Amr Awadallah is the Chief Technology Officer of Cloudera, a data management and analytics platform based on Apache Hadoop. Before co-founding Cloudera in 2008, Awadallah served as Vice President of Product Intelligence Engineering at Yahoo!, running one of the very first organizations to use Hadoop for data analysis and business intelligence. Awadallah joined Yahoo! after the company acquired his first startup, VivaSmart, in July 2000. With the fourth industrial revolution upon us—where the lines between the physical, digital and biological spheres are blurred by the world of big data and the fusion of technologies—Cloudera finds itself among the band of companies that are leading this change. In this interview with Enterprise Innovation, the Cloudera co-founder shares his insights on the opportunities and challenges in the digital revolution and its implications for businesses today; how organizations can derive maximum value from their data while ensuring their protection against risks; potential pitfalls and mistakes companies make when using big data for business advantage; and what lies beyond big data analytics.
  • What we (think we) know about meritocracies
    "Meritocracy," writes Christopher Hayes in his 2012 book Twilight of the Elites, "represents a rare point of consensus in our increasingly polarized politics. It undergirds our debates, but is never itself the subject of them, because belief in it is so widely shared." Meritocratic thinking, in other words, is prevalent today; thinking rigorously about meritocracy, however, is much more rare.
  • A new perspective on meritocracy
    Meritocracy is a common element of open organizations: They prosper by fostering a less-hierarchical culture where "the best ideas win." But what does meritocracy really mean for open organizations, and why does it matter? And how do open organizations make meritocracy work in practice? Some research and thinking I've done over the last six months have convinced me such questions are less simple—and perhaps more important—than may first meet the eye.

  • Three new FOSS umbrella organisations in Europe
    So far, the options available to a project are either to establish its own organisation or to join an existing organisation, neither of which may fit well for the project. The existing organisations are either specialised in a specific technology or one of the few technology-neutral umbrella organisations in the US, such as Software in the Public Interest, the Apache Software Foundation, or the Software Freedom Conservancy (SFC). If there is already a technology-specific organisation (e.g. GNOME Foundation, KDE e.V., Plone Foundation) that fits a project’s needs, that may well make a good match.
  • ESA affirms Open Access policy for images, videos and data / Digital Agenda
    ESA today announced it has adopted an Open Access policy for its content such as still images, videos and selected sets of data. For more than two decades, ESA has been sharing vast amounts of information, imagery and data with scientists, industry, media and the public at large via digital platforms such as the web and social media. ESA’s evolving information management policy increases these opportunities. In particular, a new Open Access policy for ESA’s information and data will now facilitate broadest use and reuse of the material for the general public, media, the educational sector, partners and anybody else seeking to utilise and build upon it.
