- What the Hell: Some researchers at the University of Michigan have created an 8-bit processor incorporating pneumatic gates, pointing toward a computer that doesn’t require electricity at all. Make sure you watch the videos. It’s not going to beat your local Beowulf cluster on the speed side, but if you find yourself on a planet where nanomachines eat electrical conductors (as they did in my novel The Cunning Blood) such a machine might well come in handy.
- The Make Blog aggregated probably the best writeup of a homebrew railgun that I’ve ever seen. Make sure you prowl around the site, and make double sure you see the pictures and watch the videos!
- Bill Cherepy sent me a link to a short writeup on the still-hypothetical Asus 2-screen ebook reader. You can use it as a netbook, with one screen doubling as a touch keyboard, or you can use it as a facing-pages ebook reader display. Now, displays are probably the most expensive part of devices like this, so I doubt a 2-screen model will be the low cost leader. Still, it’s an idea that’s well worth a try. (And please, guys, make the card slot XDHC compatible, ok?)

- Back in the ’50s there was a product called Siz that was (I kid you not) foaming Napalm in a spray can. It was for starting charcoal. Lileks does a wonderful riff on it. (They had such indescribably cool toys in the ’50s.)

- When I was a kid, Verne/Wells films were all the rage, and by far my favoriate was Journey to the Center of the Earth . Small boys aren’t equipped to appreciate Arlene Dahl, but I was quite the fan of James “Nemo” Mason, and was willing to tolerate Pat Boone even though my older cousin Diane thought he was “dreamy.” The film was dazzling in 1959, especially the “cave of crystals,” which flooded out when dreamy Pat Boone got too agressive with a geologists’ pick. Well, some years ago Mexican miners discovered a real cave of crystals 1200 feet beneath Naica, Mexico that makes those old 1959 movie sets look sick. National Geographic has more textual coverage, and it’s worth noting that the cavern is unliveable without life support suits, being at a constant 122 degrees and 90% humidity, which is worse than Houston, if that were possible.

- On Monday I returned the last third-pass page proofs (of a very gnarly part of the book, the partial instruction reference) and if the publisher’s schedule is to be believed, Assembly Language Step By Step, Third Edition goes on press tomorrow. Real books should be out of the bindery and in the warehouse by September 22.
- We came within a few hours of having a sunspot-free calendar month in August, but then very late Monday night, a barely visible sunspeck showed up, ruined the run, and then immediately started to vanish. The sunspot minimum appears to be heading for a double bottom, and there are people at NASA suggesting that deeper mechanisms are changing within the sun, and we may be a long time before seeing anything like a proper sunspot peak. So much for DXCC on 10M.
- Cory Doctorow speaks up on cloud computing, the goal of which, he says, is to allow companies to make money in a mature computing market by charging you month by month for computional facilities that you already have at home. So tell me: How many people actually collaborate in the Cloud, as a percentage of people who actually compute? I think it’s in low single digits–which suggests that the Cloud as an idea is something like 95% scam.
- If you’re following Michael Arrington’s CrunchPad project, the CrunchPadFans blog is worth a visit every week or so. It’s a little sparse, but there hasn’t been much news generally on the long-awaited gadget in recent weeks. I intuit that it would make a jack-fine ebook reader, if software to handle the major formats is included or installable.
- And speaking of ebook formats, Sony has announced that it will be supporting the EPUB format in its new reader products, days after Google’s announcement that it will be doing the same within its Google Books system. EPUB is a reflowable open standard not controlled by any particular firm, and if I had to finger a winner in the ebook standards wars (at least for primarily textual works) this would be it.
- Further relevant to ebooks is a reader app I’ve been fooling with on Ubuntu: Okular, which is nominally a PDF viewer but can open and display lots of other formats, including DjVu, CHM help files, Epub, Plucker, MobiPocket, and a few others. Although it’s a KDE 4 app, I’ve had no difficulty making Okular run under GNOME. Okular on a suitable handheld Linux-enabled device could make a helluvan ebook reader.
- And Okular led me to the KDE on Windows project, which aims to create native-code ports of KDE apps to Windows, with an installer to make it easy for non-techies. It’s early and the product doesn’t look as easy as it should be, but then again…it’s early.
- I’ve discovered a much higher-resolution photo of the old Turtle Wax building at the Ashland/Ogden/Madison intersection in Chicago here. We would pass that building on the way to my grandfather’s house Back of the Yards back in the late 1950s, and my mother would always point out the 25-foot tall turtle on the top of it. Cool building, too, turtle or not. Gone now, alas–the turtle and the building both.

- Probably because I don’t work that much in the realm of historic images, I did not know that scanned or photographic copies of public-domain images are also in the public domain, at least in the US. I’ve been gathering scans of pre-1923 artwork for possible use on book covers for several years now, but the uncertain origin (and thus the copyright status) of most of the copies themselves has given me pause. I guess it’s time to end the pause and hit Play.
- We’re currently in peak season for noctilucent clouds, which are high-altitude ice-crystal plumes of mysterious origin. Because they’re so high, they reflect sunlight long after the land beneath them is in night-time darkness. NLCs are appearing farther south recently for reasons not understood; predictably, it’s been ascribed to global warming, but some research indicates that southward excursions of NLCs are a proxy for low solar activity, which we’ve certainly been seeing the last couple of years. (Spaceweather has been covering NLCs a lot in recently weeks, with good photos.)

- We’ve now had cheap desktop CD-R burners for at least ten years, and the lifetime of the media is supposedly about that. Here’s a reasonable article on optical disc longevity that isn’t from an industry source. Has anybody noticed any burned (not stamped) data discs from the 90s going bad yet?
- When we lived in Arizona, I used to climb an elderly neighbor’s thirty-foot-tall grapefruit tree to help her get the high-hanging fruit. I was in my early forties and that was the last time I ever climbed trees on a systematic basis. If I had to do it again, I would probably stay on the ground and build something like this.
- Has Bucky Fuller’s Cloud 9 cities concept ever been used in SF? There’s not much to be found online about them, but in brief, he was talking about geodesic spheres as much as several miles in diameter, each containing whole cities that could float via thermal lift by virtue of as little as a degree or two of temperature delta between inside and outside. I’ve been imagining Cloud 9 spheres made of drumlin parts (with possibly a Hilbert drive ring around the sphere’s equator) and I’m a little surprised that I haven’t already seen the idea used in fiction, given that Bucky wrote about it in 1960.

- Here’s a nice, high-school physics level lab demonstration of an aluminum air battery, made from aluminum foil, aquarium charcoal, salt water, and a paper towel. A few of these in series will run a simple solid-state radio. It would be fun to figure out how to expand the concept into something a little more durable, with thicker aluminum plates, in some kind of container that will confine the messy materials and yet admit oxygen to sustain the reaction.
- Damned if the photo of this beambot doesn’t remind me of the Ed Emshwiller F&SF cover for “Callahan and the Wheelies,” a 1960 story by Stephen Barr that I blatantly imitated in my own high-school fiction.
- When I first got into computing in the midlate 1970s I had a number of CPU green cards, but was always a little puzzled that none of them were…green. (The COSMAC green card was blue, and the 8080 green card was white.) In truth, I didn’t know at the time why everybody called them “green cards,” and if you still don’t know, here’s a site where you can see the real deal. (Thanks to Richard Haley for the link.)
- And from Richard’s own hand comes a list of instruction mnemonics that you won’t find on most green cards, of whatever color. My favorite is EMW, Emulate Maytag Washer, which the crotchety frontloading 3330 disk packs back at Xerox building 214 were very good at doing, except that they were in the spin cycle all the damned time.
- Google Books has mounted most (if not quite all) of a fascinating book called Hi There, Boys and Girls! which is a history of local children’s TV programming in the US. The book is organized by TV markets around the country, and the Google Books version is intriguing for how much material is actually available for free. The Chicago material is available, and excellent, if not as detailed as Jack Mulqueen’s full-book treatment in The Golden Age of Chicago Children’s Television, which has a much more limited Google Books preview.
- We are getting close to the release of Michael Arrington’s Crunchpad Internet tablet, but little or nothing has been said about the only thing I really want it for: a large-display ebook reader. It needs an SDHC slot (which I think it has) and some decent ebook software (anybody’s guess) but given those two things, it could remake the ebook biz. July is flying. Wherezit at, Mike?

The Cloud in Your Pocket
We’ve been getting rained on a lot this week, in more ways than one. Carol’s garden is going gangbusters, and I’ve never seen an explosion of wildflowers along my accustomed hiking paths as I’m seeing right now. There’s a bee shortage somewhere in the country, I’ve heard, but the little buggers are thronging the wildflowers here. Temps are deliciously cool, for June, which seems to be a trend this year.
On the flipside, some dorks broke into my hosting directory a few days ago and inserted porn spam links into all my static HTML. They tried to modify the PHP in my instances of the Gallery photo manager for purposes unclear, but Gallery stopped working and I had to delete both instances. (I have backups of all the photos and captions and will reinstall as time permits.)
That whole adventure happened while I was on deadline reading copyedits on the first five chapters, and it did not endear me to cloud computing. I’ve had some time to think about the whole sorry mess, and some larger questions arise:
- How do we keep crap like that from happening? (This is a mostly rhetorical question; I’m not sure that we can.)
- Apart from portability (i.e., accessing your data on the road) what’s the real value-add in cloud computing? Remember to figure in the cost-benefit of having to find and sometimes pay dearly for a broadband connection to use it.
- And if portability is the only value-add, why screw with something as inherently pricey and dicey as the Cloud?
Why not put the Cloud in your pocket?
I just ordered my very first 32GB thumb drive. I skipped the 16 GB size entirely, because my trusty and much-missed 2001 Thinkpad X21 had a 32 GB hard drive, and I never filled it up. It contained all my major apps (Word, Excel, PowerPoint, MapPoint, InDesign) and all my Internet apps, plus a scattering of smaller utilities. It also contained a great deal of data, including everything I had written electronically since 1979, though in truth much of the bulk lay in MP3s. Document files are remarkably small.
One of the most significant trends of the last two years is the explosion in “portable” apps, meaning software that does not require a formal installation process beyond unzipping it into a directory. Nothing goes into the Registry, nor into \windows\system32. The whole app lives in a single folder. What a brilliant idea! (Wait…all software used to be like that…)
There have always been portable apps, but for the last fifteen years or so it’s been seen as declasse to produce them. Why? Think for a second: Once installed, a conventional Windows app can’t simply be lifted out of its folder and copied to another machine. It was one of the earliest forms of stealth DRM, invented, I suspect, specifically to keep MS Office from wandering.
No more. There are now lots of portable packages, many or most of them completely free. See PortableApps and 100 Portable Apps for Your USB Stick. You can get OpenOffice, the Gimp, Thunderbird, Firefox, Kompozer, and just about anything else you might need in portable versions. You can unzip them into directories on a thumb drive, and execute them from File Manager. (There are also portable app managers like CodySafe that give you a separate UI for your portables and stick data.) Portables run like conventional Windows apps, except that they don’t crap in your machine.
I got into portable apps while thinking about degunking for Windows. The Registry is Gunk Central, and much havoc is caused by duelling and mis-versioned DLLs dropped like softball-sized hailstones into the system32 directory. When I got my new Core 2 Quad last summer, I resolved to install only what conventional apps I absolutely needed, and use portable apps for everything that I could. The results? I have a cleaner-running machine that boots fast and has a remarkable lack of line items in Task Manager’s Processes tab. I’ve tried to stick with FOSS apps, because commercial apps are always down there in your taskbar popping up nag balloons, trying to upsell you or force updates down your throat.
It’s worked very well. What I want to try is having a single largish thumb drive containing not only data but also the programs used to manage it. Other people have been doing this for years, and it’s time I gave it a try. In the meantime, my view of the Cloud cooks down to this:
Take from the Cloud what can only be had from the Cloud–and keep the rest in your pocket.
Marvell’s SheevaPlug
Two years ago, I discovered PowerLine networking and have used it ever since, first to cover a CAT5E “dead spot” in my Colorado house, and more recently to finesse Wi-Fi outages at Carol’s sister’s house. The Linksys PLE200 Ethernet bridges work fantastically well within our house, and have sufficient bandwidth to stream HD video. With one unit near my router downstairs, I can take the other unit and plug in to the Internet anywhere in the house where there’s a power outlet, and there are power outlets every six or eight feet on every wall in the place. So whereas it’s not quite Internet Anywhere, it’s pretty damned close.
I remember thinking with a smirk back when I first got the units that it wouldn’t be too long before somebody made Linux run on it. And suppose somebody did? What would be the use of that?
Well, a use occurred to me a few months later, though it wasn’t anything I felt like discussing at the time. But this morning I saw something on Slashdot that made me change my mind. It’s the Marvell SheevaPlug. It’s an 1.2 GHz ARM-based Linux box in a wall wart, and bears a striking resemblance to the various PowerLine brick bridges that I’ve seen in the last few years. It’s got a gigabit Ethernet port and a USB 2.0 connector, but no other interfaces. You talk to it through the Ethernet port, and can use the USB port for external mass storage or whatever. It takes its power from the wall outlet it’s plugged into. It’s only missing one (obvious) thing: PowerLine connectivity.
One of these plugged into a wall is cute, but not a major win. Equipping them with jelly-bean PowerLine logic changes everything: One plugged into a wall downstairs with a terabyte hard drive on the USB port, and three or four plugged into the wall upstairs acting as USB peripherals to computers, and you’ve got a media distribution system for cheap, with no dependence on CAT5 or even Wi-Fi. You can do that now via Wi-Fi, piecing together a system from components. Products based on the SheevaPlug (which is actually an OEM-able hardware platform) already allow this, with more or less kafeuthering, usually more. (See HipServ and PogoPlug.) My take is that if the idea is in fact to make a cheap and simple media distribution component for home use, PowerLine is a no-brainer.
The SheevaPlug does not have PowerLine connectivity, but someday it or something like it will. And a cheap (in my view, ~$80) implementation could turn an entire hotel into a LAN party–a LAN party where nobody knows precisely who or where anybody else is.
I’m not sure if that’s important to gamers or not. I’m not a gamer and have never been to a LAN party. I have read online, however, that there are LAN parties at which the games are almost a secondary attraction, behind the unusual ability to share files at high speeds with few (if some) concerns about Big Media’s enforcers. At public LAN parties, it’s always possible that the MPAA could plant a mole at the party. But if everybody’s sitting quietly in their hotel rooms either gaming or sharing files (or both) any moles tuning in with their own Sheevas would have a hard time knowing whom to call the cops on. Unlike Wi-Fi, it’s hard to get a directional fix on a PowerLine node, and without routable IP addresses, there’s no way to connect a node to a particular person.
This may or may not be technically feasible; it’s an SF concept for me, and I have a couple of story ideas that follow from it or at least make use of it. Much depends on how hotels are actually wired–and if something like this catches on, I’m guessing that they’ll begin soldering a low-pass filter on the 110v feed to every room.
But in the meantime, it’s cool to see my long-time prediction that computers will eventually become bulges between peripherals moving toward actualization. (I did not guess that computers would become their own wall-warts.) And there’s much more to say about what I call “backnets,” which are networks that happen in unexpected ways, often parasitically on other connections. Backnets may be the third coming of pirate radio, in which tweaking the Man is often more important than accomplishing anything useful. (Is there any fiction about pirate radio out there that you know of? Drop titles in the comments if you’ve got any. Thanks!)
For Small Values of “Thumb”
The last time we had the nerd gang over, Eric Bowersox gave me a couple of the smallest USB thumb drives I have ever seen. The unit shown above right is 1 3/8″ long X 1/2″ wide and holds 512MB. It was a promo giveaway branded with AMD’s logo, containing tech spec PDFs for AMD’s CPUs and motherboards. I included a 4 GB Cruzer Micro Skin in the photo for comparison, but what doesn’t show well is the little gadget’s thickness, which is just about 1/16″, or a hair over 2 mm.
The unit Eric gave me is a Kingmax Super Stick, and in case that’s too big for ya, there is also a Kingmax Super Stick Mini that is another 4 mm shorter. I was not surprised to see that they have higher-capacity units, from 2GB up to 16GB. The 4GB unit sells on Amazon for $6.95, and the 16 GB for only $35.75. Kingmax knows its market, or at least understands careless geek laundry habits, since the product is advertised as “…washer and dryer SAFE!”
A drive that small is basically the size of the glass-epoxy connection tang inside a conventional USB flash drive, minus the metal guide that ordinarily surrounds it. The downside to a thumb drive without the metal guide is that it can plug into a USB port two ways, only one of which is useful. I made that mistake the first time I tried it, but I recognize that there’s no harm done plugging it in the wrong way, because in that event there’s no electrical connection between drive and port.
It’s a little small for my own personal thumbs, but may be a reasonable form factor for plugging into netbooks or smuggling across borders stuffed up one nostril. What I find more notable is the fact that 512MB flash drives are now so cheap that they can be produced as trade-show freebies. The size of our data isn’t increasing, and the capacity of cheap storage is expanding astonishingly fast. What’s the bandwidth of a $5, 64 GB nostril drive crammed full of 25,000 MP3s and passed from one hand to another? Media creators are wondering in their nightmares, and if they aren’t, they should be, because we’ll be there before you know it.
