Interactive Photo-Map: Oil and Rocks and Squiggly Things

No audio narration, but there is a spiffy map that you can scroll around in, complete with icons you can click on to see the photos and some text to go with them. Who could ask for anything more? Besides audio narration in my mellifluous voice, that is.

Since the embedded “Google Maps” image doesn’t seem to appear in the RSS feeds, I’m adding it after the “Continue Reading” link below – please do so and let me know how it works. As usual, suggestions are welcome – I’d like to do more of this kind of thing when I have time to travel. (Suggestions for future locations or themes are welcome as well).

JelloLlamaJalama Beach Teaser Post

Okay, I finally worked out what was screwing up my geolocation (the new dates for Daylight Losings Time) and had a chance to sit down for a while today to work on cleaning up my photos for upload. I really need to get a new digital camera that handles low-light conditions much better. I did manage to get a photo of the Majestic Natural Glory of the Los Angeles river from the train, though, despite the tinted windows. Take a look:

Ain’t it pretty? They say the waters of the Los Angeles river are so pristine that they taste like (Miller|Coors|Bud|Insert-Your-Least-Favorite-Beer-Here) Lite®!

Here’s a question for everyone who reads this: I’m planning to turn the Jalama Beach photos and track into an interactive map post (Hopefully tomorrow [Sunday, April 5th]). Anybody want audio narration to go with it? Also, is anyone but me playing with the Mozilla Firefox 3.1(/3.5) beta, or the latest experimental Opera or Safari browsers, i.e. browsers that support the HTML5 <audio> tag?

And, since I titled this post “Jalama Beach teaser”, and while I’m talking about Pristine Natural Beauty, here’s a sample:

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?…

Magical Miracle Elixir: “better than bleach”. Secret ingredient? Bleach.

The Los Angeles Times published a bewilderingly hyped article today about an electrolytic device that makes “miracle” liquid. The article describes what actually is a kind of nifty gadget that uses an electrical current and a couple of semi-permeable membranes to generate (separately but simultaneously) a “degreaser” and a “sanitizer” out of ordinary salt and tapwater. They say that not only can you use one output to clean your dishes, the other one is “10 times more effective than bleach in killing bacteria”(insert a long string of exclamation points there). I just have one thing to say about that:

A fundamental aspect of my personal philosophy is this: If you cannot play with something, you have not mastered it, and if you do not play with it, you will not master it.

I can sit here and read for hours, but it’s time I actually put my hands on some brewing again. I have a pound each of wheat and amber dried malt extract, an ounce of a low-bitterness (~2.9% alpha-acids) pellet hops, a packet of medium-attenuation dried beer yeast, two 39 millihogshead plastic containers that I can use as fermenters, an early-20th-century hand-cranked blower/bellows, a hot glue gun, a gallon of pineapple juice, some air-line tubing, a cabinet full of spices (including, of course, ginger), at least one small room air-filter, several pounds of honey, perhaps half a cup of granular erythritol, glycerol, a whole mess of glass bottles and bottlecaps, a variety of high-caffeine black tea bags, miscellaneous kitchen implements, a couple of copper-coated scouring pads, a selection of two-liter PETE bottles, iodophor concentrate, a hydrometer, a somewhat overstressed and twisted mind, a wife, four cats, and a dog. What shall I make?

I’m thinking I should aim for a mildly sweet brew with a ginger bite, perhaps adding a bit of tea or pepper if the sweetness needs balancing – but of course part of the goal of the exercise here will be to try to adapt to whatever I’m getting along the way…


What shall I do?!?

Colored nigiri rice colored and shaped like 'Marshmallow Peeps'Since natural forces have not (yet) secured a replacement job for my Minister of Domestic Affairs, I’m forced to appeal to the supernatural and assume that the Spirits are angry with me for not yet having performed the appropriate Devouring Of The Soft Pink Bunnies ritual this year…so I’m devouring a package of pink “Peeps” bunnies. No doubt good fortune will finally swiftly follow…

Meanwhile, I’m poking around in patents and scientific papers, pondering a few different possible topics for the next post:

  • More on the “Nathan System” of brewing, with reference to patents and the intended purpose thereof (and pondering how to construct a homebrew-scale “Hillbilly Biotech™” version thereof)
  • Fermented foods and beverages review and request for ones I haven’t heard of yet
  • Bad poetry
  • The previously mentioned paper on getting yeast cells to eat themselves to death
  • A post composed mainly of photographs of myself with no clothes
  • The current collection of quasi-random scientific publications I’m wading through for fun
  • Some computer-related nerdity
  • Anything else

Please place your suggestions in the comments, I beg of you. Even if they are just long strings of profane threats of violence should I elect to post on [insert forbidden topic here].

“Improvements in the Fermentation and Maturation of Beers”

Judging by my webserver’s logs, almost nobody actually bothers to click through the blog-carnival host’s site to read my Giant’s Shoulders” posts. This could be due to a secret conspiracy involving famous bloggers and several shadowy government agencies. I suppose, though, that there’s a chance that simply nobody but me is that interested in non-medical microbiology. Well…today’s post is an attempt to disprove that concept, for what aspect of non-medical microbiology could be more universally appealing than beer?

Unfortunately, in the middle of trying to assemble this posting, I see the February host has decided to put the carnival up a day early, undercutting my experiment. See, I told you it was a conspiracy! I suspect the Secret Cabal of Popular Bloggers was getting pressure from the Trilateral Comission, the NSA, and Pepsico® to silence me, so they had to do it. At least being forced to miss one, I am now free from the “I’ve been posting to these since the beginning, I can’t miss one now!” treadmill.

That means, loyal readers, that you get to see this post a month before everyone else! Hooray! Stick it to The Man™! Comically paranoid rantings aside, it also means I can split this up into more than one post, which may be more readable considering how much ground the article in question actually covers. Today’s Classic Scientific Paper is:

Nathan, L:”Improvements in the fermentation and maturation of beers.”; 1930; J. Inst. Brewing; 36; pp538-550

I ran across this reference recently while working my way through an industrial microbiology text[1] that I checked out of the campus library. According to the author of this text, “The use of cylindro-conical vessels in the brewing of lager was first proposed by Nathan (1930)[…]”, referring to the now-ubiquitous style of metal fermenter seen in small brewpubs and “MegaBladderwashCo” large-scale industrial breweries alike. Based on this I had expected the reference to be a digression on the design, construction, and testing of the fermenter. When inter-library loan managed to get me a copy of the paper, I found something much more involved.

The paper is a presentation made by Dr. Leopold Nathan in 1930 to the Scottish section of the Institute of Brewing. The topic was not simply a fermenter design but the entire “Nathan System” of brewing which appears to be the basis of modern large-scale brewing, especially for Lager-type beers. At this point, Dr. Nathan had apparently already been developing this system for about thirty years (apparently starting with a German patent in 1908, which I’ve yet to find a copy of), so as you might guess it was not just a single invention but a whole collection of them. Compared to the more rustic techniques frequently in use at the time, the “Nathan System” of brewing promised to provide faster production, more consistent results, and a better final product. It does this mainly by improving the removal of “trub” (the cloudy bits of protein and such that settle out of the malt-water – the “wort” – after you boil it), preventing infection of the beer with undesirable organisms during the cooling, hops-infusion, and aeration, and by eliminating the need to “age” the brew to make it palatable. The most important improvement in the “Nathan Process” seems to be how he treats the wort between boiling and “pitching”.

For anyone unfamiliar with the brewing process, here’s a Grossly Oversimplified review of the steps:

  • Boil some malt-sugar dissolved in water to sterilize it and to help coagulate the “trub” proteins so they’ll settle out of the liquid.
  • Cool the malt solution and aerate it so that the yeast will grow in it.
  • “Pitch” your yeast into the now-cooled-and-aerated malt-water, in a container that will keep air out while letting out the carbon dioxide bubbles that the yeast will give of during the fermentation
  • Wait until the yeast get done fermenting, then put the resulting liquid into bottles/kegs/casks/whatever.

Diagram showing the containment vessel, cooling system, and sterile-air generator for the 'Nathan method' of brewing
I’ve added a couple of labels to that image from the paper, which I’m guessing was itself copied from a contemporary patent of Dr. Nathan’s. There are two purposes to this part of the Nathan Process – To cool and aerate the wort quickly without exposing it to risk of contamination, and to move trub and volatile sulfur compounds that would otherwise make the brew taste and smell funny. The hot boiled wort is pumped directly into an insulated vat (labelled “A” in the diagram) from the boiling kettle. At this stage the wort is hot enough to prevent anything from landing in it and growing. Then, the hot wort is pumped from the top of this vat into a clean-room containing a cooling device that the wort is poured on, cooling and aerating it as it flows through. Infection is prevented here by the fact that the room has a continuous stream of “sterilized” (or at least well-filtered) air, which is exhausted through the vent in the ceiling. The cooled, aerated wort is then pumped back out of the room and into the bottom of the insulated container below the still-hot wort.

Because of the large open cooling room with its constant stream of clean air, the cooling and aeration step also allows the volatile sulfurous compounds of “jungbukett” (The “Bouquet of Youth”; the unpleasant smells and tastes of immature beer, described in this paper as ‘onion-like’) to evaporate off and be carried away. Since waiting for these compounds to break down was apparently a primary reason for having to “age” lager before selling it, this not only improves the quality but eliminates the need to store the beer for months after fermentation.

The now-chilled wort then rests back in vat “A” and the trub settles out onto horizontal plates inside the vat, where it stays behind when the clarified wort is pumped out to the fermenters.

I did some poking around, and this appears to be what is described in US Patent# 1,581,194 (application filed in August of 1921), in case you are bored and want to look that up. If not, or if you don’t want to deal with the frustrating hassle of trying to view TIFF files in your browser, I intend to provide a followup post with some more details of the process and some interesting bits I found in it, and I’ll include a pdf of the patents, assuming anyone wants them.

Oh, one last thing – I’ve had no luck getting any biographical information about Dr. Leopold Nathan. Unfortunately when you search for “Leopold Nathan”, the results are clogged with references to a murdering smartass named “Nathan Leopold” instead. Doesn’t Google™ realize that brewmeisters are far more important than obscure murderers? No pictures of him, either, so I can’t even say whether his hairstyle is cooler than Eduard Buchner’s or not.

They say “When life gives you lemons, make lemonade”. What if life gives you snot instead?

Someone's slime-covered handNow, see, this is what happens when I’m too poor to buy nice distracting new toys for myself. (No, not the hand in the picture – that’s not mine, it’s just there for illustration.)

I found a pot that I’d rinsed well but then left filled with water in the sink to soak, to help remove the last of the rice bits stuck to it. It hadn’t gotten stinky or fuzzy or anything, but it had gone…viscous. Like a light sewing-machine oil. Naturally, I took appropriate action to deal with it.

I fed it.

Glucose (“dextrose”), to be precise. It’s since been dumped into an old glass jar and the original pot thoroughly scrubbed with hot soapy water. At this point (a day later) the slime is closer to the viscosity of vegetable oil now. And I fed it again.

I wonder what it is? I mean, obviously it’s bacteria-snot, but what kind? I suppose if I had some iodine I could check to see if it’s a polysaccharide (evidently this test works on polysaccharides besides starch). If only I had a microscope, I could at least get some basic hints as to what’s producing the slime. Maybe I can maintain a culture and figure it out later, if I can ever afford a real microscope. Perhaps I could even attempt a strain-improvement program to increase the production rate…

Uh…I did mention I was a nerd, right? Okay then.

I wonder if anyone at work has a bacteriological microscope setup that I could use?…

I have a shocking confession to make.

I think I may be a nerd.

No, no, don’t try to deny it. I think it pretty much has to be true for someone who reads a 10-page scientific paper (hover or click here to see the reference) in order to learn that bacteria-snot is slimy. Yes, I am a nerd. And for that I am deeply, deeply….

Oh, who am I kidding? I like being a nerd.

Stainless Steel fermenters at a breweryFor one thing, being a nerd allows me to fully enjoy one of the perks that my job gives me – namely access to a lot of scientific papers that I otherwise wouldn’t be able to afford to obtain access to from the greedy [insert your favority profanity here] who insist on charging $30 for permission to look at a decades-old articles for a day. I should add that this perk includes Inter-Library Loan for articles that I can’t get online, and the service on campus is great so far. Same day delivery of a classic article from 1930 in what I’m guessing most people would probably consider an obscure journal.

It doesn’t have quite the same thing in it that I expected from the source that pointed me to it, but I think it can still be considered “classic”. I need to re-read it more carefully to make a final decision on this, but I think I have my next “The Giant’s Shoulders” article in time for this month’s upcoming issue. And, yes, the picture attached to this post is a hint (and, no, it’s not directly related to the bacteria-snot article mentioned above in any way…)
