All the episodes of Brainwagon Radio, the podcast of brainwagon.org.

Brainwagon Radio: Oscar Review Show

Where your host teams with his charming wife to give the fashion rundown of the Oscars, and to review all the movies we didn’t see (most of the Oscar nominated) and the ones we did see in 2005. This was our first team effort: your charity in listening is appreciated for this stupendously long episode. Hope you have fun with it.

Brainwagon Radio: Upgrading to WordPress 1.5

Where your host describes his mostly good experience in upgrading from WordPress 1.2 to WordPress 1.5.

Links from the show:

  • You can get WordPress 1.5 from wordpress.org.
  • I’m enjoying Build Your Own All Terrain Robot. I’ll probably be ordering some windshield wiper motors for my robotics project in the next week, maybe from bgmicro.
  • Still loving my Dell Axim x50v. I like reading the web on the small screen. I’ll probably work up some better templates for WordPress so you can read (and listen to!) Brainwagon wherever you are, and whatever limited device you have.

That’s it for this week. Sorry for the sparse episode. Still have gmail accounts available, drop me an email to get one!

Brainwagon Radio: Photography in Public, Blogging in the Workplace, and More

Where your host chats about photography in public, blogging in the workplace, and his usual assortment of podcasting and gadget related experiences.

Links from the show:

  • I’ve used netstumbler in the past while wardriving, but their version for the Pocket PC called ministumbler doesn’t appear to work on the Dell Axim x50v. I did find that WiFiFoFum did work, and managed to log 175 access points between here and the movie theater three miles away last night.
  • A reader recommended iGuidance, which includes the capability to make MPG movies of your GPS position moving over maps. Kind of cute, but at $109.00, it’s hard to justify. For that price, Microsoft Street and Trips includes a GPS.
  • Steve is a freelance photographer over at shooter.net who was recently bullied by SF Muni and police for violating a law which doesn’t exist. Such shameful abuses of police power are all to common in the post 9/11 world. Read his story!
  • Former Google blogger Mark Jen was fired for blogging about his experiences and opinions of Google. I think it would behoove companies not to rely on “common-sense” as proposed by some, but rather to develop specific guidelines about what their expectation with respect to blogging activities, similar to the Internet usage guidelines that most companies seem to have drafted.
  • Matthew Fordahl wrote this article which has driven an increase in traffic to my website.
  • I still have more gmail accounts to give away! Send me an email and I’ll send you an invite.
  • I bought an iPod shuffle last week, which proved to be defective. Picked up the replacement yesterday, and it works great!
  • Book of the week: Predicting Presidential Elections and Other Things by Ray C. Fair
  • Does anyone know of a club for robot construction in the Bay Area? Drop me an email!.
  • Embarrassingly, I couldn’t find a link to the NPR show on stride piano that I mentioned, so as a substitute try out this tribute to Fats Waller.

Brainwagon Radio: Dell Axim x50v, iPod shuffle, and the Soweto Gospel Choir

Where your host wakes up early and knocks out another podcast, even while suffering through an at-times painful head cold. Hope the sound of nasal drip didn’t offend.

Links from the show:

  • My new PDA is a Dell Axim x50v. 802.11, Bluetooth, VGA resolution screen, both SD and CompactFlash slots, lots to love!
  • Got a good scoop on sale prices for the PDA from techbargains.com.
  • I picked up Microsoft Streets and Trips, which includes PC, PocketPC and Smartphone versions of their mapping software. Seems to work really well!
  • I’m having difficulty with the iPod shuffle I bought for my wife yesterday. Back to the Apple Store later today to get it worked out.
  • Music today was from NPR : Soweto Gospel Choir: ‘Voices from Heaven’ I really love this kind of music, even though admittedly I know nothing about it. 🙂

Addendum: I believe by my at times unreliable count that this was podcast number fifty! Thanks to all who have patiently listened to my drivel.

Brainwagon Radio: New, but Still Noisy Recording and the NSLU2

Wherein your host tries out his new Behringer UB802 mixer (with mixed results) and goes on about his new project: hacking on “the Slug”, a Linksys NSLU2 network storage device.

For all the enthusiastic support that I’ve read for the Behringer as a decent mixer for the beginner, I’m still getting a substantial amount of noise from the mic preamplifier, and the simple noise reduction filters in Audacity really is not very good at removing. The result of not running them is that occasionally the noise pops on and off as the quantization of the mp3 encoder either decides to encode or discard it. The result of running the noise reduction is a warbly, chirpy quality to my voice which is even more distracting. Are people really having good results with mixer? What am I doing wrong? All comments and advice on my audio quality are cheerfully accepted.

Oh, incidently, you can read this skeptical view of who will make money doing podcasts. Frankly, since I don’t view my podcast as a revenue stream, I hardly care whether what he says is true or not.

You can see a page hosted on my slug or even a simple weblog written in perl that can be hosted on the slug. Nifty huh, for a gadget which cost $80 and runs on about 1 watt of power. This hardware can serve as the prototype for my “digital homesteading device”, an idea I’ve been trying to refine. Imagine a device which you could carry with you. Imagine that it could attach to your home broadband, and would register itself with one of the dynamic DNS servers so that everyone could find it. Imagine it had lots of flash storage, and could serve as your weblog server, your wiki server, your photo gallery, serve your podcasts and maybe even stream audio to other servers. Imagine further it was a simple, inexpensive, worry free device. That’s what I think of as my digital homestead. Not a server which can handle a slashdotting, but just a little place to hang your digital hat, which lowers the barrier between content creation (in other words, living your life) and sharing it with the world at large.

Is there a market for such a thing? I have no idea, but it is a fun thing to think about and try to build.

Addendum: For some strange reason, the initial version of this podcast was borked in some strange way: at two points during the podcast an annoying blast of noise occurred. I pulled it within the first twenty minutes (I usually download and listen to podcasts after publishing them, and discovered this annoying noise relatively quickly) and have replaced it with a new version. I apologize for anyone’s problems.

Brainwagon Radio: Small Webservers and Telescope Making

Where your noble host apologizes for his infrequent podcasts, and goes on to describe why he thinks small devices are interesting as webservers, with some suggestions. Also, the history of his involvement in telescope making.

My interest in these small webservers are for implementing an idea that I’ve been calling a digital homestead: a small, self-sufficient presence on the web. I’ll probably expand upon this more in the future.

Links from the show:

  • I wrote about some small devices suitable for serving small websites yesterday. Try looking at polkadot ninja for an example of a website which runs entirely from a small device.
  • My infrequently updated website telescopemaking.org is due for a freshening update. Previously I just handcoded the pages, but it’s obvious that it would be good to use some different software. Can anyone recommend a CMS and/or Wiki that would be the foundation of a good community website? The simpler the better. If you have some suggestions, send me an email.
  • Target has a 10% coupon you can use to order the Mac mini. Haven’t tried it, don’t know about delivery, just saw it on techbargains.com.

Errata: I know the word is “metropolis”, not “metrolopis”. Chalk one up for Spoonerisms.

Brainwagon Radio: Wil Wheaton’s Booksigning

Where your host forgoes his usual activities at Chabot Observatory and instead accompanies his wife to Wil Wheaton’s booksigning at the Border’s in Union Square.

As is true of many things, it was actually my wife who took notice of his blogging activities. I’ve read his blog off and on for quite some time, and have just become more and more impressed as time goes on. What I find most attractive about his day-to-day writings is that you can see the conflict that we all have within us: the conflict between our ego which tells us we are great and our doubts which tell us that we are failures. As an actor (and a struggling one), Wil experiences this inner battle with a frequency that may be higher than your typical individual, but we all can empathize. What I think is really remarkable is that while he still fights these battles, he’s clearly winning. Not winning in the sense that these battles no longer trouble him: only conceited asses never suffer from self doubt, but rather in the sense that he seems satisfied with the ride. He takes joy in his wife and children. He can now look back on his Star Trek experience, and he can look forward to a bright future as a writer, as a speaker, doing improv, and probably a bunch of things he hasn’t even thought of yet.

It’s great to see such a nice guy survive his early success and become a well rounded adult.

He also took time in the beginning to mention how terrificly empowering blogs are, repeating some of the themes that I’ve mentioned from time to time in these pages and in my podcasts. He’s a guy who realizes the power of the Internet is that we don’t have to approach so called “gatekeepers” for permission to participate in popular media: we just need very modest computer equipment and an Internet connection. He was really plugging the Internet as a vehicle for public expression. Right on!

Wil went way over on time, and then patiently signed and posed for photographs, doubtlessly listening to dozens of people’s stories, nodding patiently and good naturedly. When my wife went up to sign, he wrote a very nice note thanking her for her support, and noted that she had one of the very early copies of Dancing Barefoot. Wil, you get my thumbs up. Keep up the good work.

Brainwagon Radio: New Years Goals, Women in Podcasting and a Mellow Track

Where your host talks a bit about his goals for the New Year, chats about the newly announced Apple Mini and iPod Shuffle, rambles (probably incoherently) about the perceived gap between men and women in technical fields, and finishes with a mellow track from online record label Magnatune.

Some links:

  • Do you really need a link to Apple?
  • I build (or more accurately, used to build) telescopes. I hope to finish (nay, plan to finish) my 12.5″ Newtonian in 2005.
  • I’ve started actually running. According to some, I’m probably pushing myself too hard, but I’d like to run a 10k in 2005.
  • Getting Things Done by David Allen has some interesting tips on trying to get organized. The geek in me immediately wants to find some electronic organizer thing to make it all easy. Lazy.
  • 43 Folders turned me on to Allen’s book. Kudos to them.
  • Amy Gahran has been trying to find women’s voices in podcasting, and they seem to be few and far between. Her January 11th podcast is a plea for more women in podcasting.

    Frankly, I haven’t a clue why more women aren’t involved in podcasting. I suspect that it is merely a reflection of the relatively small proportion of individuals who (say) go into graduate school in computer science. Why that occurs is also a bit of a mystery to me. Lack of mentors? Discouragement from parents and teachers? Desire to begin families? None of these answers seem entirely adequate. If there is a “podcast gap”, is there something we should (or even can) do about it?

  • The closing track is from Falling You’s Touch, and is titled something about eve. Very relaxing.

Things to look forward to next time: a report on Wil Wheaton’s book signing in SF and a movie review of Electra… Stay tuned!

Brainwagon Radio: Miscellaneous Rambling

Where your host blinks the sleep from his eyes, relates his experience with swapping operating systems on his laptop, and tells the story of how he came to work at Pixar and what he did on the Incredibles.

Expanding on my operating system debacle:

  • I never got Fedora Core 3 to have acceptable record quality. I also experienced a number of Firefox crashes which I hadn’t seen before. Not sure what was going on, but I decided to get back on more familiar ground and install FreeBSD 5.3 on it. (I’ve used FreeBSD a lot more than Linux.)
  • FreeBSD 5.3 installed easily, but when I tried to do a kernel recompile, I would get random segmentation faults from gcc. Usually such faults indicate bad hardware, and while I hadn’t noticed any problems like this before, I didn’t immediately discount the notion that the laptop could become less reliable when it overheated.
  • On the other hand, I thought it might be a problem with gcc 3.4 or something else having to do with 5.3. So I reinstalled 4.10-RELEASE on the laptop. After a problem with incorrect probing of the network device (it autodetected into hw-loopback mode) and noticing a problem with the sound driver (begins lound, but tails off after 15 seconds on the initial use, seems fine afterwards) I did a kernel/world recompile. The laptop shut itself off during the compile. Very strange, and could indicate an overheating condition.
  • Now, I’ve come full circle. Back to WinXP SP2, because I suspect I’m going to have to call HP to get this resolved (not under warranty anymore unfortunately). Surprisingly though, the laptop seems to be running cooler now, with less use of the fan than it has previously, even when I began with WinXP.

Additionally, here are the items that I got from Powell’s Books when I was in Portland:

Brainwagon Radio: A Minor Revolt, Linux on the Laptop

my desktop!Wherein your host describes his pique with Windows XP and describes his installation of Fedora Core 3 onto his laptop, followed by his recording of a podcast using the new software setup. Links from the show:

  • I chose Fedora Core for my Linux variant. It works rather well, and has the most polished installation of any Linux distribution I tried.
  • The ndiswrapper project allows you to use Windows network drivers on Linux. This allowed me to use my Belkin F5D7010 card (an 802.11g card) which would have otherwise been unsupported. Seems to work fine, even without the kernel compile they recommend.
  • You can get audacity packages prebuilt for Fedora Core 3 from Dag’s repository. I also installed mplayer from his packages, as well as some other packages.
  • Can anyone tell me of a cheaper bluetooth GPS than the Delorme Bluelogger?

Quality note: The sound is a bit crackly, which appears to not be a problem with the microphone. It may actually be a software issue. I’m looking into it.

Free! Free from the shackles of Microsoft!

Now, back to playing Halflife 2 on my other box which still runs WinXP.

Brainwagon Radio: Boxing Day, with some Gift Reviews

On this 44th edition of Brainwagon Radio, your host apologizes for his lack of podcasting over the holiday, but gives brief reviews of some of the toys that were acquired during this 2004 holiday season:

I’m off to face terror of post Christmas shopping. Enjoy!

Brainwagon Radio: Christmas Prep, My Wife, Referer Spam and BitTorrent

Where your host complains about his perfect storm of auto repair, switches back to his laptop for improved sound quality, is interrupted by the missus, and talks briefly about referer spam and BitTorrent. I think this very well might be my most boring podcast ever, but what can I say: I’m preoccupied by the holiday.

I’m experiencing very slow access to my hosting service, not sure what the trouble is, but hopefully this will clear up shortly.

Addendum: it seems better now.

Brainwagon Radio: Dead KVM Switch, Rants, Dickens and Mediocre Audio

In trying to fix his previous noise problems, your host appears to have squelched that a bit, but ends up with clippy audio. Sigh.

More stuff:

Brainwagon Radio: Kudos, Drawing and Helix DNA Server

Wherein your host lists a number of people who have said nice things about us, and mentions the weekend’s projects: a new icon redesign for brainwagon and Helix DNA Server.

Items mentioned in the podcast:

Brainwagon Radio: Too Long Since the Last One

Damn, it’s been nearly a week since I put out my last one, and this was painful to put out. Hopefully it isn’t too painful to listen to.

Items from the show:

  • Shameless plug for my Cinnamon Bear Podcast.
  • I upgraded this weblog to use the latest version of the CG Powerpack.
  • I rambled about the phase vocoder some more. mostly incoherently, plugging papers that I’ve mentioned before.
  • I extol the virtues of cheese once again. Have you considered that the key ingredients in Welsh Rabbit are in fact all ancient foods? History in one dish.
  • The gents at SawStop have electric saws which detect when fingers get in them and break quickly to keep you from lopping off your finger.
  • An Internet Archive “gem”: Superman battles Japoteurs in an interesting (?) look back into wartime propaganda.
  • Need to convert MPEG2’s from archive.org to a DVD? I wrote up how to do that once before using command line programs. Works great because it doesn’t re-encode the video.
  • Want a Matlab compatible language? Try Octave. Need more Octave libraries? Try octave-forge.
  • Try wearing a Santa hat wherever you go.
  • Closing music: We Wish You a Merry Christmas by T. Stipe
