Woe is me (some more)

We’re back from our all too short stress-management vacate-shun. I’m chronically underslept (indeed, I ought to be in bed right now) and now I think I’m coming down with a generic Obnoxious Respiratory Ailment for the third time in as many months, which is extremely unusual for me, and which I definitely Do Not Want. Also, it turns out that as usual, Motorola cellphones are crippled. My Razr V3 apparently doesn’t allow applications to access the camera, so there’s no way for me to cram a functional datamatrix barcode decoder onto it. And the built-in wireless networking in Igor (my venerable 3½-year-old laptop) appears to have died…

I need a new cellphone. And a microscope. And a “netbook”. And a digital camera that handles low-light conditions and close-ups better. (And a pony?…) Still, things aren’t all bad, for all my whining.

A DataMatrix barcode painted in watercolors...I did manage to get some interesting pictures on the trip, at least, along with GPS tracks for geolocation purposes. Also, wine jelly and interesting spices from generous family members we were visiting, and even some avocado honey from a little roadside produce stand on the way back to the train station for the trip back.

I’m going to bed now. Hopefully after work tomorrow or this weekend I’ll be putting up another post (and start posting more often again). Anybody want to see pictures of oil and rocks from JelloLlamaJalama Beach, or the majestic Los Angeles River?

A cheap techno-toy concept to distract me from my woes…

A DataMatrix barcode with a 'secret' message...It’s been a relatively awful month here, to tell the truth, but we’re still hanging on so far. Hopefully things will improve soon. In the meantime, I’m having as much fun as I can get away with without spending any real money. Mining old patents for interesting gadgets and ideas, for example…did you know that Google has a US Patent search? And unlike the USPTO, you can actually get a PDF of old patents, not just try to view them as “TIFF” images in a plugin that you may or may not have for your browser and may or may not even work if you do…However, my quest for old designs for industrial brewing equipment and ozone generators is not the subject of this particular post.

One thing I find I like to do for fun with my computer is sort of the opposite of what most people seem to do for fun with their computers. Most people seem to treat their computers as grossly overpriced video-game devices, whose main purpose is to connect people to fake worlds to interact with. “Computer games”. Bah. Humbug. The computer is the game, boys and girls. I like to instead find ways to connect my computer to the real world. I suppose that’s where I get my interest in neogeography, and Asterisk, and home automation (which I’ve only dabbled with but still fascinates me), and so forth.

My latest discovery of a cheap real-world/computer interface is barcodes.

More specifically, I’ve discovered that there’s finally a working project that lets me read and write Data Matrix barcodes. I ran into the project when it was mentioned in the
“New Projects” section of the March 2009 “Linux Journal” (you won’t be able to actually read the article at the link unless you’re either a subscriber, or you wait until they finally open it to the public, though you might also find a copy of the magazine at the bookstore). The actual project in question is libdmtx, and they provide some basic software for generating and, more importantly, decoding these barcodes, which means I can finally actually play with them myself.

There’s an irritating “functional fixedness” issue with these barcodes. There’s an implicit assumption that they are only for one of two things – either they are for inventory tracking (i.e. they encode serial numbers or some proprietary equivalent), which renders them essentially meaningless for anyone but the entity doing the tracking, or they may be used like the QRCode barcodes popular in Japan, which are usually assumed to be used specifically to encode a company’s website URL for “consumers” to decode with their cellphone cameras. Again: Humbug! “Consumers” can go conjugate themselves. “Consumers” are the screwups who made it possible to destroy the world economy, pollute the planet, and make vampire crap a popular “mainstream” genre. No, it’s time we paid a little less attention to catering to “consumers” and gave some love to “participants” instead.

See, both Data Matrix and QRCode barcodes can encode up to a kilobyte or so worth of any kind of data, which might then be stuck in just about any kind of place where someone might see it and take a picture of it (either for immediate decoding or for later).

If this sounds familiar to you, it may be that you remember hearing about a “Hobo Code“, which wandering homeless folks might use to encode visual messages for others with small pictograms. The catch is that since in that context you have to be able to keep the entire “dictionary” of what each symbol means in your head, you’re kind of limited to a small number of specific messages. On the other hand, one ought to be able to hypothetically cram a couple of SMS/”Twitter”-sized messages into a pattern of dots not much bigger than a postage stamp…or conversely stomped out on a giant scale in a wheat field like an especially nerdy “crop circle” just in time for Google Maps’ latest satellite imagery update.

I happened to be at an office-supply store today and was kind of surprised at the variety of things are now available to be shoved through a laser printer. Not only greeting cards and mailing labels, but a variety of self-adhesive and even refrigerator-magnet sheets. I saw they even had blank bumper stickers. Never mind serial numbers and “consumers” websites – you could stick all kinds of messages in all kinds of places with this.

A tip or warning for future diners at a restaurant (“Ask for ‘Chef Special #3’, it’s not on the menu but it’s great!” or “be nice to the waitress or the chef will spit in your food” for example) might be encoded on a small sticker or card and hidden underneath the table. You might encode your personal website URL or just a friendly greeting to be stuck to the inside cover of a Bookscrossing book along with it’s ID number. You might encode a time and place for a meeting as a geostring on printed on little magnetic squares to for members of the Secret Society (or Linux Users’ Group?) that you belong to, or to be included as an “album art” image in the metadata of a geolocated sound or video recording. You might compose original short poems or haiku and leave them in random business-card racks for the bemusement of technically-inclined strangers…

I think the stress must be getting to me, because it’s usually about this point in my thought processes that in a corner of my brain a voice pipes up, saying “What the hell’s wrong with you? This doesn’t sound like you at all! You’re starting to sound like one of those artsy-fartsy techno neo-hippies that gather at things like Burning Man or guest-post at BoingBoing, babbling about nerdy art projects and ‘culture’!”. Then another corner pipes up with “Hey, it might be kind of fun to go to Burning Man one of these years”, and then another pops up with “I like pie!” and everything erupts in chaos. Next thing I know, some indeterminate amount of time has gone by without me noticing and I suddenly realize I’m dangling from a rope over a highway wearing nothing but a pair of SpiderMan™ underpants and a thick coating of cocoa butter, still clutching a handful of LED “Throwies” and looking down at the nice folks offering me a nice warm jacket with extra-long wraparound sleeves…

But I feel MUCH better now…

Am I insane, or can any of you think of other uses for this? Or is that not an “or” question?…

“Geomicroblogging”? “Microgeoblogging”?

I don’t know what it should be called…but anyway, I put up a page where I can try to organize my allegedly spiffy idea . After my little “Proof of concept” experiment with audio geomicroblogging during the holidays, I’ve decided that the concept is indeed at least fun to play with. Since I’m still too poor to buy myself any really expensive toys or take a long luxury vacation, I figure I can amuse myself by trying to turn my experiment into a “real” system that someone might actually want to use. I’ve posted my current idea and plans for the first release at the link up there. I figure getting to the first basic implementation will take a few days to a few weeks, mainly depending on whether anyone but me likes the idea (if it seems interesting to anyone else, there’s a lot more reason to focus on getting it done than if it’s just a crazy idea that everyone else hates…)

Coming Soon to a Bigroom.org blog post near you!

I got a little money for Christmas, but I’m feeling quite guilty as I didn’t really have the time and money to reciprocate in advance. I also haven’t been able to figure out what to spend it on until now. Now, I have a solution for both problems.

Xanthomonas campestris growing in a petri dish and exuding slimeI intend to spend it all on fermentation-related food ingredients and do some experimentation with sweet-tasting foods. Initially, in addition to flavors (spices and whatnot), I need to track down bulk quantities of:

  • Erythritol, which is a virtually non-caloric sugar alcohol which unlike sorbitol and so forth is not normally prone to cause gastric distress, and unlike Xylitol is not hazardous for beloved household pets. Better still, it actually is very tasty unlike that nasty hippy “Stevia” crap (which isn’t produced by fermentation anyway, as far as I know).
  • Food-grade Glycerol (“Glycerine”), which I hypothesize is close enough to the structure of Erythritol to mix well with it and help the erythritol dissolve (and hopefully prevent crystallization, much the same way the “corn syrup” does with sucrose).
  • Xanthan Gum. MMmmmmm…edible bacteria-snot. (Okay, for all that this sounds disgusting, it’s really somewhat similar to pectin, which like xanthan gum is a polysaccharide. Pectin is just fruit-snot rather than bacteria snot. Dietarily, both count as “soluble fiber”.)

There are probably other ingredients I can come up with as well. For those of you out there who are owed gifts: Chewy candies, hard candies, baked goods, and/or beverages, what’s your preference for my initial experimentation? Assuming anyone’s interested, I will probably blog my results…

Meanwhile, I’ve also been thinking about geolocation, geotagging of audio and video media, and Asterisk again. I want to take the lessons learned from my playing with the “Where Was I?” prototype and turn it into a real geolocation system, integrating with Asterisk and Laconica (which turned out to be easier to set up than I’d feared – I’ve now got my own Laconica server at http://omniblab.dogphilosophy.net/laconica, though I need to sit down and activate the IM integration (Twitter may have abandoned IM, but it reportedly works fine in Laconica).

It also turns out that you can use Asterisk with cellphones(!), at least if they have bluetooth. That’s handy to know…

Argh – too much to do, not enough time!…

Oh boy. This is “bad”.

(Note the “scare quotes” around “bad” up there…)I woke up kind of late this morning, which is probably just as well as I think I really needed the sleep before I load up the car with stuff from the old house and make the ~1600 mile (about 2575km or 83.45 picoparsecs) return journey. As a bribe to myself for making this trip, there are two places I had been considering stopping for a bit on the way back. One of those two is New Belgium Brewing Company in Fort Collins, Colorado. In order to do this, though, I obviously need to arrange to be going through Fort Collins (around 8-9 hours from here) while they’re open. The thing is, there’s really not much point in stopping from my perspective unless they happen to have what I’m really interested in – their not-always-available limited-release “La Folie” (link from the image goes to the page describing it) and possibly their seasonal “Frambozen“. Last time I went by it appeared they always had some La Folie on tap at the tasting counter but not in bottles for take-out.

It turns out New Belgium is open on Saturday until 6pm. And they have both La Folie and Frambozen in bottles there right now.

The other possible stop is Lava Hot Springs, Idaho, where I find it very enjoyable to lounge in the hot springs amid all the snow. However, they open at 9am, so even if I get up really early to make it to Fort Collins before New Belgium closes, I can’t spend any time in the hot springs until 9am anyway, so I’d never make it from the Hot Springs to Fort Collins on the same day. I could, of course, lounge at the hot spring today and then hit Fort Collins tomorrow morning, stopping somewhere between Central Wyoming and Fort Collins tonight, but that could mean the return journey spanning three days rather than two.

However, the weather on this side of Idaho and Wyoming looks most passable today especially later in the afternoon when the roads have been cleared off well, and it looks like getting across the bad wind and snow on the Eastern side of the Wyoming may be safer and better tomorrow morning rather than today.

So, basically, the entire Universe (or at least that portion of it in charge of weather for this region of the country) is obviously telling me that I should take my time loading up and getting out of town, and then go ahead and stop at Lava Hot Springs for a little while to relax before continuing on to somewhere around Rawlins or so, and then resume in the morning which should just coincidentally put me going through Fort Collins in the Late-Morning to Early Afternoon time frame, when New Belgium Brewing is open.

I mean, I don’t want to stop and enjoy myself. Really, I want to be a good boy and drive back in the quickest, most efficient way possible, but who am I to thwart what is the Obvious Will of the Universe? (Supernaturalism makes some of the best excuses…)

In other news, I did manage to fix the Stupid Mistake™ in my little “Where Was I?” application for Asterisk, so now not only do the location updates happen but also the conversion of the associated voice update to MP3 for listening now happens automagically as well. I also fixed the hard time-limit, so updates shouldn’t cut off at 30 seconds like the one from Fort Collins did on the 24th. If you keep an eye on the page and everything goes well for me, you may catch an update from Lava Hot Springs later in the day. If you are especially bored (or are being paid by a Secret Government Agency or Vast International Conspiracy or Santa Claus to spy on me) I will try to do an update from there while sitting on the steps in view of the East Webcam. If so, I’ll be the tiny figure waving at the camera from the steps. If you happen to be watching at the right time, you might catch me there to gaze upon my magnificent pixellated spiffitude. Just don’t look directly at it or you may go blind…

Naturally, a live update from New Belgium Brewing Company is planned for tomorrow as well. After I return I can work on making my little application more interesting (embedded audio player, nicer presentation, maybe an embedded map, ability to come back later and attach related pictures…) and masssaged into a condition that wouldn’t be too embarassing to let others use. This “live neogeographical netcasting” thing is too much fun to keep just to myself. (I wonder how hard it would be to interface this with the Laconica microblogging system?…)

Further bulletins as events warrant…

Geotagging through Asterisk?

Between telemarketers annoying me into getting my upgrade to Asterisk 1.6 finished and the hasty long-overdue road-trip back to and from Idaho again, I’m reminded of an idea that has been fluttering around in the back of my head, not unlike a small bat in the top of a bell tower.

My vast hordes of cult-like fans always seem to want to know where I am. This is obviously an issue in a case where I’m going to be driving 1600 miles, then turning around and driving back, over the span of 4-6 days. It would be pretty easy to set up something on a web page somewhere with some kind of map. The real problem is – how do I update the map?

In some places, I could stop for a while, haul out Igor, boot up, find a public wireless network connection to the internet, and do the update that way. However, that’s time-consuming and awkward, and I want to get this trip successfully completed as quickly as I can. Plus, it’s not always easy to find public network access points, especially through the barren, windy, snowdrift-covered wastelands of Southern Wyoming where a chunk of my route will take me. I have a hypothetical solution, however…

Obscure scientific papers, Mad Science, Travel, and other randomness

First – an amazingly astute observation that I’m ashamed to have not previously noticed myself (click image to go to it’s original site and see it full-size…):
Most 'Mad Scientists' are actually just 'mad engineers'...

I’m proud to say that I think testing Mad Hypotheses is great, and will continue to try to be a Mad Scientist. And a “Dirty Old Man” someday, but that’s a whole separate issue.

Second – I am really loving the perks of my new job – namely access to the college library system. I had previously mentioned (see last couple of paragraphs) a certain article that I wanted to get my hands on:

Greenberg LA:”The Definition of an Intoxicating Beverage”;Q J Stud Alcohol. 1955 Jun;16(2):316-25

Not only does the medical library have copies of a Czechoslovakian microbiology journal, the main library had a set of this old journal, too. I have my bedtime reading for tonight…

Thirdly – Another Giant’s Shoulders carnival has come and gone. I now believe that Eduard Buchner had hit upon not only a useful truth of living systems, but also a nifty alternative “mad scientist” hairstyle. Now I need to come up with one for next month. It’s been getting me thinking, though. That blog carnival is intended for “Classic” papers. Implied is that the papers are somehow important to the development of some scientific field or other. I’d like to see a variation on the “old papers” theme focussing on random old papers (where “old” might mean a few years or decades, depending on the subject) that people have found useful or interesting. Stuff that isn’t necessarily ground-breaking and has perhaps been forgotten or lost to obscurity but still has useful things to teach us. Naturally, I’m thinking especially Microbiology (and especially Microbiology other than Medicine) and Food Science. The Carnival could be called something like “Second Chance Science” or something of the sort. Just a thought.

Fourth – speaking of “Microbiology Other Than Medicine” and Food Science, apparently The National Academies of Science want to know what scientific topics people most want to read about. As usual, “microbiology” appears to have been relegated in their breakdown to merely a subset of either medicine/diseases, “biology”, and perhaps a small subset of “energy” and “Feeding the World” (no, seriously). The survey includes space to tell them what they’re missing – I heartily encourage anyone who cares to make sure you take the survey, and mention industrial and environmental microbiology and food science as subjects they shouldn’t continue to neglect.

And, finally – next week I need to make a very-long-overdue run back up to Idaho to grab some things from the old house and make sure it’s still standing, the water’s really turned off, nothing unnecessary is running, etc. 1600 miles of driving each way. Ugh. Anybody got any good recommendations for things to listen to on the trip? Other than having a chance to finally grab some things that I am missing, maybe I’ll at least have a chance to visit New Belgium Brewing Company again, since my route goes right past it. So long as I’m not driving by on Christmas day (when I assume they’ll be closed) I may have a chance.

The “Stir-Fried Random” podcast, et al

Almost time for the first real episode of “Stir-Fried Random”. It’s still a bit short (about 10 minutes or so is what it looks like I’ll have) but the sound quality is a bit improved. It’s not all frivolous, either – there’s high culture (Opera) and science (the first of my Microbiology Microlectures) in it.

I was also plotting to intermittently post what I’m thinking of as “Book-And-Record” audio files, each associated with a single picture (embedded as “album art” as well as likely in the blog post presenting it) saying something about subject of the picture…

Possible audio show, and “ask me anything!”…

You may be wondering where I’ve been. (If not, in order to spare my fragile little ego, please pretend that you were. Thank you.) Well, mostly I’ve been in my car driving to and from my spiffy new job.

This hasn’t left me with much time to blog lately, which annoys me a bit. On the other hand, the commute is long enough that I run out of netcasts to listen to during the week, leaving me with driving time back and forth during which I could conceivably be doing something productive.

Continue reading Possible audio show, and “ask me anything!”…

“Berry-Pomegranate” is the new “Strawberry-Kiwi”. Discuss.

We actually (finally) got power and internet back LAST weekend, but this week’s been too hectic to get back into proper blogging again yet. Spending the day dealing with unexpectedly severe, sudden acute “hay-fever” type symptoms hasn’t helped (fortunately, that seems to be just about under control now, hopefully I’ll be feeling more normal after a decent night’s sleep.)

We did actually get out on the lake for a long lake-spanking session last weekend. I finally managed to get some time to go through the pictures yesterday, so there’ll be another interactive photo-map sometime soon (I hope) – and of course more fermentation.

Meanwhile, is it just me or is “pomegranate” the new “in” flavor, much as “kiwi” was about ten years ago?
