1. Cryptsetup benchmarks for a Dell 17r.

    01 August 2013

    For no good reason today I decided to run some cryptsetup benchmarks on Windbringer. The only really significant change to the systemware configuration is that Windbringer is now running Linux kernel version 3.9.4-1-ARCH.

    [drwho@windbringer ~]$ cryptsetup benchmark

  2. Cryptoparty presentation: Whole Disk Encryption

    31 July 2013

    At the DC Cryptoparty in October of 2012 I did two presentations: One on GnuPG and one on whole disk encryption. While I'd put the GnuPG presentation online I hadn't done the same for the disk encryption one because I had to update it after the cryptoparty to take into account new information acquired that afternoon regarding MacOSX and Windows. I did so, converted the OpenOffice Presentation deck into a PDF, PGP signed them, and uploaded them this afternoon.

    v1.0 of the WDE presentation is now available for download:

  3. Gareth Branwyn: Borg Like Me.

    29 July 2013

    Older denizens of the Net probably remember the name Gareth Branwyn. His name and visage were well known amongst people who were active in what came to be known as the cyberculture of the late 1980's and early 1990's, that weird mish-mash of hacker culture, people who identified as cyberpunks, psychedelic culture, rave culture, and other tiny social groups so far out on the fringe that they never really coalesced but instead moved in the cracks and fissues left in the wake of those other groups. Most of us remember two major projects he worked on at the time, the …

  4. Scalemates Three.

    26 July 2013

    As before, much of my spare time in the past two weeks has been spent making two more Scalemate plushies so I could give one of them to my little nephew Brandon this weekend as a "Hi, welcome to the world" present. I wanted to make two of them in case I messed up, and also to have a choice of which one to give him because they weren't going to be identical or perfect, but ideally better than the first one I sewed. I wanted them to be fairly bright and cheerful looking, the better to get his attention …

  6. Recovering.

    21 July 2013

    Since v0.5b of Byzantium Linux hit the Net, all of us have been taking the opportunity to get a little R&R before proceeding to the fifth and final milestone, which is writing up everything that happened in the previous six months. That's going to be a lot of stuff, but we've got good notes, a bunch of blog posts, and no shortage of lessons learned through the development process. I think when we sit down and get to work, we'll get it knocked out, edited, and published in not a very much time. I'll also be in a …

  7. Byzantium Linux v0.5b is official!

    18 July 2013

    A brief update before I go back to bed:

    Byzantium Linux v0.5b is officially released. We've changed a significant number of things under the hood for the fourth ISC development milestone, such as completely revamping the build process by splitting the repository into a number of other modules, making the captive portal page more reliable, and updating packages to their latest stable version. All of us are kind of fried right now - that's why we called this release Sleep Deprivation - so we've made it available on the usual mirror sites as well as a brand-new BitTorrent tracker.

    Give it …

  8. Revisiting some old hobbies.

    10 July 2013

    Life's busy right now. I'm being pulled in several different directions, sometimes simultaneously, which hasn't left a lot of time or compute cycles to do any writing. What I have had time for lately has been a lot of "fire and forget" stuff, which doesn't really do anyone any good. Failing that, long hours at my day job doing what I do best. I don't think any more need be said on that point.

    The next release of Byzantium Linux (v0.5b) is due in five days, so that's where most of my spare time goes - knocking out the next …

  9. Announcing Byzantium Linux v0.4b - "No sleep 'till Brooklyn!"

    01 July 2013

    Project Byzantium can now take a breather for a day or two to recuperate, so I have some time to write a hopefully coherent post during my second cup of coffee.

    Last week we wrapped up ISC development milestone number three: Addding amateur radio support to Byzantium Linux. This was probably our more difficult development effort to date, as it required that we use our relatively newly earned skills as ham radio operators to figure out a way to connect mesh networks over long distances - longer distances than 802.11 wireless can ordinarily cover. I'll not recap the entire report …
