  • ART single thread performances

    ART has been the default routing table backend in OpenBSD for some months now. That means that OpenBSD 6.0 will no longer consult the 4.3 BSD reduced radix tree to perform route lookups.

    The principal motivation for adopting a new tree implementation can be explained in three letters: SMP.

    I'll describe in a different context why and how ART is a good fit in our revamp of OpenBSD network stack. For the moment, let's have a look at the single-thread performances of this algorithm in OpenBSD -current.

  • parallel-lib: New LLVM Suproject
  • LLVM Has New "parallel-lib" Sub-Project

    This new parallelism library is described as "[hosting] the development of libraries which are aimed at enabling parallelism in code and which are also closely tied to compiler technology. Examples of libraries suitable for hosting within the parallel-libs subproject are runtime libraries and parallel math libraries. The initial candidates for inclusion in this subproject are StreamExecutor and libomptarget which would live in the streamexecutor and libomptarget subdirectories of parallel-libs, respectively."

pfSense 2.3.1 FreeBSD Firewall Gets New Update to Patch Web GUI Security Issues

Filed under
Security
BSD

Chris Buechler from pfSense announced earlier today, June 16, 2016, that there's a new maintenance update available for the pfSense 2.3.1 FreeBSD-based firewall distribution.

pfSense 2.3.1 Update 5 (2.3.1_5) is a small bugfix release for the pfSense 2.3.1 major update announced last month, and since pfSense now lets its maintainers update only individual parts of the system, we see more and more small builds like this one, which patch the most annoying issues.

ZFS Fault Management Daemon Added To FreeBSD

Filed under
BSD

The latest FreeBSD development code has integrated the zfsd daemon.

ZFSD is the ZFS Fault Management Daemon. ZFSD deals with situations like drive faults in ZFS pools with hot-spares and replacements. This comes as the ZFS file-system support in FreeBSD continues to mature and is in quite a good state for ZFS outside of Oracle.

  • Faces of FreeBSD 2016: Michael Lucas

    Back by popular demand, we’re again sharing a story from someone involved in FreeBSD with our Faces of FreeBSD series. It may be a story from someone who’s received funding from us to work on development projects, run conferences, travel to conferences, or advocate for FreeBSD. Or, it may be from someone who gives back to FreeBSD financially or in another way. Regardless, it is always from someone who is making a positive difference in the FreeBSD world.

  • 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.

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.

  • 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.

  • '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.
