The Importance of Sideloading

You haven’t seen much of me here since the first of the year because I set myself a target for writing fiction, and, micracles of miracles, I’m sticking to it. Blogging is second priority, and if I spend my creative hours working on stories, I’m likely to post a lot less in this space. (What posts I do write I hope to make longer.)

Anyway. CES 2011 is now history, and I followed it more closely than I might have in past years because I’m actively shopping for an Android slate. (I hate to call them “tablets;” we’ve had tablet PCs for almost ten years and there’s one on my desk.) I played a little with a Samsung Galaxy Tab at a Verizon store in Tampa in late November and was much impressed, even though the demo unit did not have any kind of ebook reader installed. (Wireless carriers are pushing video hard, because video will use up a lot of deliciously profitable minutes.) I’ve played with Apple’s iPad as well and have been just as impressed, but there’s a huge worm in it for me: Apple wants to absolutely control its content ecosystem, and sideloading of apps is a gnarly business. Sideloading an iPad is easier with books and music, but I’d like to try my hand at slate apps, and I’m not going to work in a playground with barbed wire around it. The open-source Android just suits my temperament better. I have some faint hope of programming Android apps in FreePascal, but Android is really a Java-like platform (apps run on the Dalvik VM, which has its own specific register-based bytecode set) and a Pascal-to-Dalvik compiler is unlikely, as much as it has precedent in the ancient UCSD P-system.

Sideloading is important in a number of ways. (The term as I use it simply means the ability to get apps and content onto a device locally through a cable or a plug-in memory unit, rather than from a tightly-controlled online store or cloud locker of some kind.) I don’t have a lot of ebooks yet, primarily because the e-ink display on my Sony Reader makes my head hurt. Furthermore, the ones I do have are a very mixed bag, from many different sources and in many different formats. I have novels, but I also have tech books, many of which have intricate art and layouts that don’t reflow. A lot of things I’ve picked off Usenet are image scans of transformer catalogs and ancient manuals for Fifties Heathkits, none of which are legible on low-res e-ink screens. I need a good high-res color display, but more significantly, I need the ability to install arbitrary apps to render any arbitrary content format, including minority formats like DjVu, which I don’t favor but must deal with occasionally. I could readily sideload the files on an iPad, but the apps to render them are another matter.

Sideloading of ebooks is still a geek thing, primarily because the ebook business is so damned young. If you can get everything you want from Amazon or Apple, cool–and almost everybody is starting from scratch, with little or no existing ebook library to deal with. In years to come, people will be jumping from device to device and reader to reader and store to store, and at each jump must face the question of how to pack along the books they’ve already paid for. DRM makes this hugely more difficult, but even in a world without DRM, different kinds of content would require local storage transfer and different rendering apps, not all of which will be readily available from the current vendor’s store, especially for new devices incorporating new OSes.

Sideloading also allows local scanning for malware, which will become increasingly important in coming years, certainly for apps but probably for compromised content files as well.

Any slate I buy will have to support sideloading of both apps and content. Android seems to be the OS for that, and I’m now watching the Motorola Xoom, a dual-core 10″ Android slate running the Honeycomb version of Android. There’s some weirdness involving the SD slot (the CES prototypes didn’t have it) but without that, there’s no sale. More intriguing for many reasons is the Notion Ink Adam, (above) which does have a MicroSD slot and 2 USB ports, and the intriguing PixelQi display. Its Android OS is a custom version that anticipates some of the Honeycomb features but is technically V2.2 Froyo with a proprietary UI. (Their blog is worth following if you’re interested in slate technology.) I just hope they don’t do a FusionGarage thing, but if they can hang in there they’ll be a contender.

I must emphasize that I’m being careful and I’m not in any particular hurry. Much of my personal Jedi self-training in recent years could be summarized as Stop wanting stuff. Buy, or buy not. There is no “want.” When jump I, know you will!

I may be the last person to aggregate this, but if you haven’t seen it yet, consider: The Sun being eclipsed simultaneously by the Moon…and the ISS! Thanks to Bill Higgins for pointing it out. (Talk about having to set up a shot!!!)
And for further astronomical boggle-fodder, consider this: A ten-year-old girl discovered a supernova a few days ago, and is the youngest person ever to do so.
Here’s a site listing a great many 19th Century and early 20th Century studio photographers, many with addresses and sometimes timeframes. All but one of the studios I’ve seen on old family photos I’ve scanned (circa 1880-1910) are listed. How useful this might be is hard to tell, but if you’re currently doing genealogical research it’s worth a bookmark.
RF Cafe has a nice table of dielectric constants, useful if you’re winding coils on odd scraps and not commercial forms or cores.
The same research yielded this short discussion of how good PVC piping is for RF use. Quick form: Most plastics are better, but they don’t make polystyrene pipe. They don’t even make polystyrene vitamin bottles anymore. (Fortunately, I still have a few in the scrap box.)
From my old friend Dennis Harris comes a pointer to Televisiontunes.com, which has short MP3 clips of 18,351 TV theme songs and all their variations. Elmer the Elephant is missing, but damn near everything else is there, from Supercar to The Ugliest Girl in Town .
Last week while we were in Chicago, my nephew Brian showed me Google Sky Map on his Android smartphone. Basically (assuming your phone “knows where it is” and when) you can hold your phone up against the sky, and it will show you what stars and planets lie in that direction, even in broad daylight. Aim the camera at your feet, and you’ll see what’s on the other side of the planet, swinging toward rising or circling the opposite pole. Way cool.
From the Words I Haven’t Heard In A Long Time Department: bric-a-brac , a collective term for odd items of low value. I realized, digging through a box in the garage, that I must hold one of the world’s largest reserves of bric-a-brac. Damn. I shoulda invested in rare earths.
Related to the above: Rubrique-a-Brac , a long-running cartoon strip by French cartoonist Gotlib. His 1971 Taume 2 collection of strips is the funniest book in French I ever read without knowing French. (I do have a French-English dictionary, which helps, but the art largely speaks for itself.)
As if the Nazgul weren’t enough: We’ve gotten word that there was once a giant stork that preyed on the Flores Island hobbits.

Akismet

I didn’t get much comment spam the first year or so that the main Contra instance was on WordPress. (The LiveJournal instance is a mirror.) I moderate all comments from new commenters, and now that the daily comment spam rate has crept from three or four up past thirty or forty, I figured it was time to do something.

So yesterday morning I installed Akismet, a server-side comment-spam detection plug-in for WordPress that applies a Bayesian signature scheme to incoming comments, and bins the ones it considers spam. Installing it was effortless, and for personal blogs like mine it’s free. (For commercial entities the Akismet service is $60/year.) So far, in about thirty hours it’s identified 80 spammy comments, which remain in the bin so you can scan for false positives if you want. Everything Akismet has fingered so far has proven to be spam. However, I’ve gotten no genuine comments on my WordPress instance since installing it. If you posted (or tried and failed to post) a comment on my WordPress instance today or yesterday, let me know. If nothing is in fact interfering with legitimate comments, this thing is a godsend, and if I sound a little nervous, it’s only that it feels maybe a little too good to be true!

[UPDATE 12/10:] Well, four comments successfully posted, and nothing spammed that shouldn’t be (or not spammed that should have been) suggests that Akismet is a win and I should stop worrying.

The MacSlow Cairo Clock Black Border Problem

Nov 18th, 2010

I’m slowly coming out from under something very like bronchitis, but I wanted to get this item posted because I see nothing about it online: When Mac Slow’s excellent Cairo Clock is installed under Ubuntu with all the desktop defaults, it does not overlay itself on the background correctly. (See screen shot at left.) This was initially a head scratcher for me, because the very same version of Cairo Clock (0.3.4) works perfectly under Ubuntu 10.4.

What I didn’t realize is that in the process of tweaking Lucid Lynx this spring (before I installed Cairo Clock) I changed the Visual Effects option from None to Normal. The clock requires something in the GNOME desktop visual effects mechanism, and when I changed Visual Effects to Normal instead of None, it worked as expected, clipping to the clock face with a nice transparent drop shadow.

The option is in the System | Preferences | Appearance dialog, under the Visual Effects tab.

Nothing more than that, and not a big deal. I’m posting it in case some other Ubuntu noob has the same problem and can’t figure it out. If I can save some poor guy an hour and some hair this easily, I will.

The base for the Geiger-Muller tubes used in all of the early Cold War era Victoreen counters (including both tubes now on my bench) is called a standard Peewee 3-pin, JEDEC A3-1. Many thanks to Jonathan O’Neal for sending along this link to a detailed spec sheet (PDF) for one of the tubes. Now I can wire up the counter I’m building for initial tests.
A couple of people have suggested using a Leyden jar instead of ordinary capacitors to collect charge for my (supposedly) steampunk Geiger counter. I imagine that a Leyden jar would be more period, and it’s certainly a good excuse to build something that I saw in every single one of the kid books on electricity I read back in the early 60s. Not real portable, though.
There is indeed an organization that helps to keep Latin functional, 2000-odd years from its original coalescence as a major world language. No psychic powers points for guessing that the organization is…the Roman Catholic Church. (Thanks to Michael Covington for the link, which, I must say ahead of things, is in…Latin.)
And Finland just racked up a huge mess of cool points with me for being the only country in the world that broadcasts the news in Latin. (Thanks to Aki Peltonen for the link.)
Jim Furstenberg put me on to photos of a round dozen Victorian submarines. The site looks to be a marvelously engaging time-waster, er, experience broadener. (Have done much of both in recent hours.)
Google just announced its own URL shortener, which will do some reasonable screening against malware. I have avoided using URL shorteners for that reason until now.
Furthermore, the new Google URL shortener will generate a QR code for you if you tack a .qr onto the end of the shortened URL.
Amazon is creating an Android app store. Peculiar? Not if the next (or next after that) Kindle generation is more than just an ebook reader.
I’m proud to say that my good sister Gretchen long ago declared that she is raising free-range kids. I wasn’t quite sure what she meant (Carol and I have none of our own) until I read this. Bravo! Now, can we make zero-tolerance policies in schools a felony? (Thanks to Pete Albrecht for the link.)
The other day I mentioned to Carol that, with “Drumlin Circus” taking on a certain steampunk flavor (it’s certainly nothing like “Drumlin Boiler”) I would probably have to buy a top hat. Her reply: “Um…you already have a top hat.” I looked on the high shelf in the closet, and shore ’nuff! I bought it for the 1999 Coriolis Millennium Christmas Party at the Biltmore Hotel in Scottsdale. I wore it exactly once, and then forgot about it. So what’s next? Spats? Or my seriously ahead-of-the-curve Chester A. Arthur facial hair?

From the Words I Didn’t Know Until Yesterday Department: bricoleur, a person who creates bricolage; that is, who pieces together useful things from odd bits that are just lying around. In other words, me.
Now, this interests me: Modkit, a GUI IDE for Arduino, with drag-and-drop “blocks” for program structures (inspired by MIT’s Scratch language for kids) and function calls. Alas, I don’t have any good way to test it (nor time to take up Arduino tinkering, as much as it appeals to me) but this is definitely headed in the right direction. I’m not sure I’d prefer it all out in the cloud, but that’s what seems to be in vogue these days.
Sometimes the universe is so startling that it looks fake. Like this.
I’m thinking that I’ll be toting an Android someday, and I was pleased to see the logo for the Android port of Firefox, called Fennec. When my father was in North Africa during WWII, he and his buddies at the AACS radio station in Mali killed time by attempting to tame the local desert fox population, generally by applying K-rations. What the fennecs thought of K-rations was not recorded, but as best I know they were not driven to extinction in the process.
I’d had this insight some years ago, while listening to one side of lame cellphone conversations in supermarkets (triggered, I’m guessing, by the invention of Bluetooth earclippie headsets) but evidently there’s some research behind it: Overheard “halfalogue” conversations are far more distracting than conversations heard in full. I know! Put it on speakerphone!
The guy who ran the UK Segway operation rode his scooter off a cliff to his unfortunate demise. Gravity’s a bitch, and overconfidence kills. (Thanks to Michael Covington for the link.)
Back when I was in college I saw a truck carrying uncounted cartons of head lettuce hit a low railroad viaduct and split open, and heads, well, rolled. Over in Japan, they’re working on the dressing side, with a major mayonnaise spill.
And from the same site, a writeup on a new Las Vegas hotel that makes significant use of solar energy, even if they didn’t actually intend to. (Did FLW have this kind of trouble?)

I think a lot of the air is going out of the whole pirates thing; surely I thought there’d be more pirate talk online yesterday, but saw virtually none. Dare we hope that declaring a holiday for a meme may be the kiss of death for that meme? I’m not sure what else will work, as they don’t respond to DDT anymore. So perhaps somebody needs to declare International Walk Like A Zombie Day. I’m open to suggestions on dealing with vampires. Suck Like A Vampire Day? They already do.

The pirates themselves are still out there, even if they’re not talking much. I got a note from the Jolly Pirate last week telling me that he has finally filled a 2 TB hard drive with MP3s, mostly downloaded from Usenet. The collection comes to 350,000 songs. He just grabs whatever gets posted, no matter what it is, and looks for duplicates when he’s bored. (He admits that about 10% may still be dupes; I’m thinking that figure is higher.) This is boggling; I wouldn’t have thought that that many songs had ever been produced in all human history. But what’s more boggling yet is that all 350,000 will fit on a $100 2 TB SATA drive. I asked him how long he’s been gathering them, but have not heard back yet. That’s just under 100 songs per day for ten years. (My guess: he’s been scrounging songs from his friends by the thousands.)

I’m anal about filenames (I’m the Degunking guy, after all) and not a hoarder to begin with, but I’ll bet others have that problem too. Perhaps someone should write a utility that compiles a database of Bayesian signatures for each MP3 file, so to easily spot mostly similar (but not bit-for-bit identical) song files having different titles. Easy Duplicate File Finder doesn’t do this. I’m not an expert at such things, but it might also be able to suggest excessively similar photos (like the endless hundreds we have of various Pack members) that might be deleted and never missed.

I’ve been using the minuscule and frighteningly response Atlantis word processor for odd documents lately, and turned on the sound effects just for jollies. Atlantis plays small sounds at certain times, including a very realistic typewriter click on each keystroke (trust me, I know what those sound like!) a typewriter bell when the line wraps (ditto) and an odd little “mew” like a kitten when it encounters a word not in its dictionary. It also plays a sound like a car horn the first time you touch a key after pressing either Caps Lock or Num Lock, which is surprisingly useful, especially for people like me who watch the keyboard as much as the screen while typing. For awhile I found this annoying, but at some point I ceased to notice it, and now when I type on close-lipped Word 2000 it “sounds funny.” Odd how quickly we adapt to small changes in our environment, quickly making them the norm. Or maybe I just miss my old Underwood Standard.

I had the strange notion today that when I finally get around to building my Geiger counter, I’m going to craft an oak-and-brass case for it, with fluted knobs, shiny trim and whatever other odd touches might be necessary to make it a steampunk artifact. Of course, then I’d need to get with my sister to design the rest of the outfit to match. (“Does this Geiger counter make my butt look small?”)

The shingles rash is spreading around the entire left half of my torso, and is so touchy now that I can’t lean back in my computer chair. So be glad you’re not here; not only am I growing contagious but am also uncharacteristically grouchy. I’ve been making some good progress on the first novella I’ve attempted in almost thirty years, but it’s increasingly difficult to get into flow with the constant electrical-ish prickliness on my back, which morphs into a weird sort of pain with any kind of contact. So I may have to set Drumlin Circus aside for awhile, and continue to gather research on the Pleistocene megafauna. (In the story, all the circus animals are megafauna now extinct on Earth.) I learned yesterday that there was once a 6,000 pound giant wombat, and am trying to get my head around the concept. Whatever else our early human ancestors did, they certainly ate well. For awhile.

It keeps a very low profile somehow, but this NOAA site is the first place I go when I want to see what a hurricane is doing. We’re a little short of hurricanes this year, but I’m good with that.
This is what a pharmacy sign looks like in some parts of Europe. Thanks to Terry Dullmaier (in Germany) for the link. Terry didn’t know if the middle neon part goes off to indicate that the pharmacy is closed. Anybody?
I’ve discovered a great little free clock app for Linux, called the Cairo Clock. It can run in 24-hour mode and is skinnable, with about two dozen different skins available, some of them pretty weird. The skin I like is called Radium, and it (by choice) has a negative weirdness factor: It looks like an old wristwatch I got from my grandfather when I was a kid, which had radium paint on the hands and hour points. The second hand actually ticks forward and then falls back a little, as second hands driven by mechanical escapements used to do. I’d run it on Windows if I could.

Bill Higgins put me on to NNDB, which is a biography site and useful for that alone…but take some time to poke at their mapping mechanism, which plots connections between significant people both living and dead. Cool factor 11 out of 10; making the maps useful probably takes more practice than I’ve been able to give it so far–and you must keep in mind that every relationship charted is somebody’s opinion of something.
There is a natural bridge on the Moon. (And I thought Straight Wall was impressive!) Thanks to Darrin Chandler for the link.

Well, I got the Mallo-Ware bowls I bought from eBay, and they were in better shape than they looked in the listing, and Dash has clearly busted his last bowl. Which leads to a thought: I used to prowl garage sales for entertainment, halfheartedly hoping to find something useful. (I once got a completely functional early-50s tube tester for fifty cents.) Now I just decide what I consider useful and go to eBay or Craigslist.
Adobe’s Flexnet copy protection system evidently writes to the MBR, and thus can make a system unbootable if it gets in a wrestling match with something else that also wants to be there. Flexnet, in fact, looks disturbingly like a rootkit from here. If I wasn’t sanguine about moving up to Adobe CS before, I sure as hell don’t intend to now.

Now that Apple has anointed the slate category, the usual suspects are coming up with their own surprisingly interesting takes on the concept.

We’re at a dog show in rural Greeley, Colorado, a little north of Denver–and right smack dab next to a huge cattle feedlot. Now, I’m a caveman and a realist–manure is the price we pay for beef–but that stuff sure do stack up and make its presence known. We kennelled QBit and Aero to simplify show logistics, but it’s funny not having Aero with us at a show. He’s a champ now, and the spotlight has shifted to Dash, who at 15 months already has 11 points (of the required 15) and one major win (of the required 2) toward his own championship. Aero was always a shy dog, and fearful at the outset. This cost him points early on, but Dash has never had any such problems, and it’s (remotely) possible that he could score a big enough win this weekend to make him a champion while still technically a puppy. (He won’t reach his majority until 18 months.) Master groomer Jimi Henton will be helping Carol make him and Jack look their best, and we have high hopes.

I just finished a dozen Lucerne eggs and I’m still alive to write about it, so the big contaminated egg thing may not be as horrible as some are making it out to be. But half a billion eggs, sheesh–and that from one company. Am I going to give up eggs? Hardly. My sole gripe is that Lucerne’s are the only eggs I can find locally in Medium, and I’ve titrated myself to a pair of Medium eggs scrambled for breakfast as what best carries me until lunchtime without any energy lapses. So I may have to fall back to a single Extra Large until I can scare up a different brand of Medium eggs. And while eggs are on the table here, does anybody see size Small or Peewee eggs sold at retail? (As best I know, these are generally sold to food producers for cakes and such.)

I bought and have been tormenting a new-ish WYSIWYG EPub editor product called Jutoh, from the guy who gave us the free ECub editor. It’s available for Windows, Linux, and Mac, and I’m testing it under Windows and Ubuntu. My first impressions are generally good, though the product still has a couple of thin spots, foremost of which is an inability to import .DOC files. More on it once I have a chance to get a couple of projects through it.

It may sound odd, but I’m pleased that Jutoh is not free software. It’s only $22, which is trivial–I’ve spent more than that just having an indifferent lunch with Carol at Village Inn. I don’t want to see the category of inexpensive commercial software die out. For a long time it seemed that software was going to cost either zero or a thousand dollars, which would mean that few solo software geeks would attempt to field an innovative utility that would not sell for hundreds but might sell for tens. I bought Atlantis some time back for $45 and love it–it generates the best EPubs of anything I’ve tried so far. (Jutoh is still in the running, but the race has barely begun.) Free software can be superb but all too often evolves slowly, if at all. Zoundry Raven, on which I write this, hasn’t been updated since 2008…though I must balance this by citing the free ebook manager Calibre, which is updated every couple of weeks.

We have lost the Star Hustler. Jack Horkheimer has gone off to see what the stars look like from the other side, and as little as I saw of him (I’ve not watched much TV in the last 40 years) I will say that he did a spectacular job making observational astronomy compelling to ordinary people, especially young people–and as goofy as he seemed sometimes, he never made me want to kick his teeth in, as all too often happens with Bill Nye. Science should not be full of itself (nor, alas, full of something else, as is the case far too often) and Jack was not. Keep looking up…maybe you’ll spot the light of the Big Bang glinting off the top of his head.
