Upgrading Wi-Fi: What, When, and Why

Filed under
Sci/Tech

Wi-Fi (802.11x) networks have been around long enough that many businesses and home users run their own. The first widely deployed standard was 802.11b, while most new hardware uses 802.11g. The latest 802.11n hardware is just around the corner. If you run an existing wireless network, is it time to upgrade?

  • Common problems in open source communities (and how to solve them)
    In her Texas Linux Fest keynote, Joan Touzet talked to us about how to improve our open source communities. Joan's talk was a series of stories about communities who have faced a crisis and then rose above it.
  • OpenStack Was Key To Building Servers.Com
    When XBT Holding S.A. decided to simplify how its subsidiaries provided global hosting, network solutions, and web development they turned to the open source cloud infrastructure platform OpenStack. By consolidating the offerings under a single service provider, Servers.com, customers can more easily browse, mix, compare and choose the most suitable services.
  • ZeroStack Comes Out of Stealth, Focused on Private Clouds
    There is another OpenStack-focused startup on the scene, and you have to appreciate its creative name: ZeroStack. The cloud computing company has come out of stealth mode to introduce a private cloud solution that it claims is easier to configure, consume and manage than any other technology on the market.
  • Apache Ignite, a Big Data Tool, Graduates as a Top-Level Project
    Only a few days ago, Apache, which is the steward for and incubates more than 350 Open Source projects, announced that Apache Lens, an open source Big Data and analytics tool, has graduated from the Apache Incubator to become a Top-Level Project (TLP). Now, the ASF has announced that Apache Ignite is to become a top-level project. It's an open source effort to build an in-memory data fabric that was driven by GridGain Systems and WANdisco.

  • How to teach student sys admins
    Students spend the 16-week long course learning practical skills using real tools. To support their systems, students learn about using support tickets and documentation by using RT and MediaWiki. To deploy and maintain their systems, they learn about configuration management using Puppet, system monitoring using Nagios, and backup and recovery using Bacula. But the broad concepts are more important than the specific software packages I just mentioned. The point is to learn, for example, configuration management, not to be trained to use Puppet. The software used by Clark is used because it works for him, but the software is flexible and changeable.

  • How open film project Cosmos Laundromat made Blender better
    If you're not familiar with the string of open projects that the Blender Institute has kicked out over the years, you might not be familiar with the term "open movie." Simply put, not only is Cosmos Laundromat produced using free and open source tools like Blender, GIMP, Krita, and Inkscape, but the film itself, and all of its assets—models, textures, character rigs, animations, all of it—are available under a Creative Commons Attribution (CC-BY) license. Want to see what a production character rig looks like? Or know how that giant color tornado was created? How about actually using a character (or just a prop) in your own project? Maybe you even want to redo the entire film to your own tastes. It's an open movie! You can!

  • The thin line between good and bad automation
    I don't like automation -- I love it. I whisper sweet nothings, come 'round with flowers, and buy milkshakes for automation. I've even stood outside the window with a boombox for automation. I will go out of my way to automate tasks that, while they are not terribly tedious, I don't want to have to remember exactly how to do them somewhere down the road, when months have gone by since the last time I had to relearn them.
  • The new IT is all about the customer
    Open source code. GitHub and other cloud repositories enable developers to share and consume code for almost any purpose imaginable. This reflects today's practical, non-ideological open source culture: Why code it yourself if someone else is offering it free under the most liberal license imaginable?

  • the peculiar libretunnel situation
    The author of stunnel has (once, twice) asserted that stunnel may not be used with LibreSSL, only with OpenSSL. This is perhaps a strange thing for free software to do, and it creates the potential for some very weird consequences. First, some background. The OpenSSL license and the GPL are both free software licenses, but they are different flavors of freedom, meaning you can’t mix them. It would be like mixing savory and sweet. Can’t do it. Alright, so maybe technically you can do it, but you’re not supposed to. The flavor, er, freedom police will come get you. One workaround is for the GPL software to say, oh, but maybe wait, here’s an exception. (Does this make the software more or less free?) Here’s a longer explanation with sample exception.
  • FreeBSD on Beagle Bone Black (with X11)
    X11 clients on the Beagle Bone Black .. that’s X11 over the network, with the X Server elsewhere. No display as yet. The FreeBSD wiki notes that there’s no (mini) HDMI driver yet. So I built some X11 programs, xauth(1) and xmessage(1), and installed them on the Bone. Since I bought a blue case for the Bone, and it is the smallest computer in the house (discounting phones .. let’s call it the smallest hackable computer in the house) the kids decided to call it smurf. Here’s a screenshot of poudriere’s text console as it builds packages.

OpenSSL Security: A Year in Review

Over the last 10 years, OpenSSL has published advisories on over 100 vulnerabilities. Many more were likely silently fixed in the early days, but in the past year our goal has been to establish a clear public record.
