USB Connectors Are Lousy

Feb 26th, 2014

I finished Chapter 6 yesterday, and have only one more chapter to write. When I was exporting my Visio drawing files to .png for submission, I discovered that a figure I drew two weeks ago had gone bad. It went bad in a way I’ve seen before: It was smaller than similar figures…and it crashed Visio. That happened to another Visio drawing file of mine a couple of years ago, when the front-panel USB port on my Antec 900 case went intermittent. I’m guessing that the data connection opened up while the file was being written, and not everything made it from the Windows filesystem to the Cruzer Micro Skin on which the file was stored. This happened to another couple of files, most of them Word documents. In those cases, I found out before I did my weekly backups. This time I didn’t, and the bad file had already propagated to my backups and overwritten the intact copy of the file. I have a hardcopy and can probably redraw it in an hour or so. Mercifully, it’s not anywhere near as complex as some of the 79 other figures I’ve drawn for the book in Visio so far. But man, I don’t want to go this way again. The Thermaltake V9 BlacX case has worked very well for me since I first described it in this space. I don’t think it’s the case’s fault, nor the fault of the Antec 900 before it.

It’s the USB ports. And I don’t know quite what to do about it.

I’ve had a personal computer since 1979, and have trudged my way through generations of removable storage since then. Here’s the list:

1979: 8″ floppies

1982: 5 1/4″ floppies

1985: Original “cafeteria tray” Bernoulli box. (Tick…tick…tick…)

1991: Original Syquest 44MB cartridge hard drive

1995: SyQuest EZ-Drive cartridge hard drive.

1996: Zip 100

1997: Zip 250

1997: Jaz. Got rid of it almost immediately, went back to Zip 100s and 250s.

2004: Thumb drives

Trouble is, I don’t know what, if anything, comes next. The problem isn’t with thumb drives themselves, nor with the Flash technology inside them. Granted, MLC makes me nervous, and I’d pay extra for SLC thumb drives if they still exist. (I don’t think they do.) The problem is entirely with the crappy connectors on the front panels of modern PCs, and with how badly we’ve abused them.

The USB interface wasn’t designed with removable storage in mind. USB was intended for interfacing to things like printers and scanners, for which you plug a cable into the port on the PC and leave it there. IBM invented the USB thumb drive in 2000, and I bought my first one in 2001. They work beautifully, but plugging and unplugging thumb drives all day can’t be good for the thin shim stock from which the port’s electrical interface is formed. It may also put stress on the copper traces on the circuit board behind the port socket. However it happens, the damned things die, and when they die, they take files (and cases) with them.

We have to be able to do better than this. The obvious solution is to recess the ports behind a channel that aligns the USB plug and keeps it from putting angular force on the port–i.e., a wiggle suppressor. Alas, there’s no standard for the bodies of USB plugs, whether for printers or thumb drives. A recessed port would keep all those rubber duckie-shaped thumb drives from plugging in, and who knows what Federal intervention that would trigger.

There have actually been eSATA thumb drives for several years now, but because eSATA ports don’t provide power (big mistake!) you have to run a cable from the thumb drive into a nearby USB port. Furthermore, even if there were eSATA ports on the front panels of tower cases (I have yet to see one) I’m not sure that the physical port would fare much better than a USB port with constant plugging and unplugging over a period of years. The eSATA spec didn’t anticipate that either. Both USB and eSATA ports seem to be made of the same flimsy stuff.

Carol made a suggestion that is functional but not elegant: Find a short USB adapter cable with a male Type A on one end and a female Type A on the other end. Leave the male plugged into the desktop, and swap out thumb drives on the female end of the cable. I actually found a 40″ specimen in the bottom of my cable snake pit, and it works. Shorter cables of that species may be available. Needless to say, it looks like hell. Cables are cheaper than cases, though.

Now, a clever hardware hacker could build the female end of the cable into some sort of base that sits beside the tower and plugs into the back. I could see that. Can see that. Will see that.

When I do, you’ll see it here.

The Weather Channel as Weak King

Feb 13th, 2014
by Jeff Duntemann.
6 comments

Back in mid-January, the Weather Channel went dark on DirecTV. There’s been a great deal of drama since then. Losing 20M viewers is one helluva kick in the crotch when you have, at best, 100M viewers and are struggling to keep the ones you have. If online comments can be believed, they’re bleeding eyeballs bigtime.

Carol and I are two of them.

I’m not a big fan of TV, which eventually turns everything it touches to crap. Carol and I never even had cable until we moved to Colorado ten years ago. The Weather Channel was a pleasant surprise. It was founded by John Coleman (of “thunderboomers” fame in Chicago) and Frank Batten in 1981. We appreciated having a detailed forecast with radar every ten minutes, and some of their people were inexplicably likeable, especially Mark Mancuso, Mike Bettes and Stephanie Abrams. We’d put it on during breakfast or anytime it looked like things were getting ugly outside.

In 2008, NBC bought TWC. That was the beginning of the end. They fired about 10% of their on-air staff, started airing content-free MSNBC news, began pushing weather/climate hysteria of every species every chance they got, and then…the coup de gras…went to the Reality TV Model. They weren’t the first; Discovery Channel and others had pounded that unmistakable path in the grass long before TWC ever found it. One lame series after another began airing anytime there wasn’t a storm that they could get breathless about. I almost understand “Storm Stories,” which at least had photos of things you’d just as soon not see every day, or maybe ever. After that, each season got weirder and weirder. “Turbine Cowboys” croaked early, because there are only so many shots you can get of daredevils repairing 100-foot-tall wind turbines. But…”Prospectors”? It’s “Duck Dynasty” with pickaxes. Now their big deal is “Highways Through Hell,” which is about roughneck Canadian tow-truck operators pulling semis out of ditches in the Canadian Rockies and getting in arguments. There’s no Local on the 8’s during any of these increasingly irrelevant reality shows. Nor, I’ll tell you with fair confidence, is there a great deal of reality.

That’s my big gripe. There are others. People online seem peculiarly agitated by TWC’s recent gimmick of naming winter storms. After Creon and Dion I was expecting Eon, Freon, Leon, Neon and Peon, and perhaps Xenon before this long, cold, ugly winter peters out. No luck so far. (After all the high-end mythological characters, the “W” storm is named “Wiley.” The hell?) Naming winter storms may be dumb. Getting upset about it is dumber.

The business model puzzles me a little. Is it cheaper to buy episodes about trash-talking Canadian truck drivers than just present the weather? Perhaps it is, once you lay out major cash for irritating New York celebrities like Al Roker. However, the people are on staff, the studios are paid for…where’s the win in reality TV? TWC seems to think that people turn on their TVs and sit down to watch The Weather Channel as a species of entertainment. For the most part, they don’t.

Anyway. DirecTV replaced TWC with WeatherNation, which resembles what TWC was when they first started out. The formula is simple: all weather, all the time. The cameras are on tripods rather than dollies, the studio is small, and there are no expensive celebrities. The computer graphics are good, and if I could get it on cable I’d wave bye-bye to TWC. I’ve begun to experiment with streaming video, now that our local Blockbuster has closed down. Said experiments have shown that I can stream WeatherNation, and once the new technology is all in place (more on which in an upcoming entry) I will.

Most of this wouldn’t even be worth mentioning at length if The Weather Channel had not begun to throw increasingly desperate tantrums, slandering DirecTV by name in house ads and claiming to be some sort of essential disaster management information service; i.e., if we don’t have a monopoly on weathercasting, people will die.

Puh-leez.

This is typical behavior of the Coastal Elite: We know what’s good for you, and if you don’t like it you’re an evil something-or-other funded by the infinitely rich Koch Brothers, or maybe the Illuminati. NBC has long had that sort of internal culture. I smell the presence of one or more Right Men–and maybe a few Right Women, though women are generally too smart for that sort of BS. Leaders earn our respect by acting with calm confidence. Calm confidence is what wins. Leaders who throw tantrums are the archetype of The Weak King. Once the tantrums start, those wooden-wheeled gallows carts can’t be far away.

What broke it all open for me was this video, which shows some guy acting like a Jack Nicholson-class psycho, tearing his DirecTV dish out by the roots and beating it with a baseball bat, until the neighbor kids run screaming and local mothers start to cover their toddlers’ eyes. C’mon. I’m supposed to flee back to The Weather Channel after seeing a revenge fantasy like this? Not fracking likely.

Being a strong king means taking your lumps, learning from your mistakes, and turning the situation around by setting ego aside and just making things work–all with calm confidence. In TWC’s case, this means dumping the unreality shows, firing Al Roker and Sam Champion, and just presenting the damned weather.

Sheesh. How hard could that be?

The Original Hard Disk

Feb 8th, 2014
by Jeff Duntemann.
11 comments

I know I have an original Bernoulli Box 10 MB cartridge somewhere. I saved one because I was sure that nobody would believe me when I waved this huge slab of plastic at them and said, “This holds 10 MB.” I think I was right. I won’t know until I find it. So I looked…

…and I found something else instead. See the photo above. Anybody recognize it? It’s part of one of the earliest hard drives in computer history. It’s such an old hard drive that it wasn’t even a hard drive. No. It was main memory.

I honestly don’t remember who manufactured it, though Sperry-Univac sounds familiar. (I threw out the case when we left Rochester in 1985.) I bought it at a hamfest for a couple of bucks just for curiosity’s sake; the old guy I bought it from said it was a hard disk, and I was skeptical. He was right, and it was probably fifteen years until Google allowed me to look for an explanation. I took the case apart and found a motor, a fairly heavy aluminum disk coated on one face with red iron oxide, and the assembly above, which has 160 magnetic heads in eight spiral groups. Roughly half the heads look like gray ferrite, and the other half like white ceramic. I’m guessing that the gray heads are write heads, and the white heads are read heads. (It could be the other way around.) The whole assembly is 9″ in diameter; the magnetic disk is 8″ with the outer 2 1/4″ coated with oxide.

So what we have here is a device that imposes 80 tracks on 2 1/4″ of oxide. The number of bits on each track remains a mystery. 1000? 2000? Somewhere in there, which suggests a total of 100,000 or perhaps 120,000 bits, which would provide about 16KB. This was RAM, not mass storage. The principle is basically the same as the magnetic drum memory systems that IBM sold with its vacuum tube machines like the 650. There were no moving parts other than the disk itself, and you can spin a disk faster than you can spin a drum. I’m guessing that the magnetic disk units like mine filled the (narrow) gap between magnetic drums and core memory. I’ve seen writeups indicating that magnetic disk storage was used for swap storage as late as the PDP 11/45 in 1972. The unit I have seemed a lot older than that.

One of the problems in researching a unit like this is that “hard disk” and “magnetic disk” have other, more modern meanings. So what needles may be are lost in the titanic haypile of newer technologies. If any of you know anything more about the technology send me a quick description or links, and I’ll post them in a future entry.

I had 8″ floppies in my first CP/M machine, and 5″ floppies in all my PCs until the 90s. I used SyQuest cartridge hard drives for years after my 1986-1992 romance with Bernoulli Box drives, which drove me nuts with their constant indexing of heads across the medium. (Tick…tick…tick…) The SyQuest cartridges spun fast and died young. There followed three generations of Zip drives, culminating in the monumentally awful Jaz. It was only in 2004 that I set aside moving parts in my removable storage, and began using thumb drives. I’ve had an SSD on my main system for eighteen months, and will be putting them in most of my lab machines as well, spurred by the need to get XP out of daily use here.

It’s sobering to remember: We’ve been spinning magnetic disks for what may well be sixty years now. We’re still spinning them, and we will be for another ten years or so at least. What other computer technology has been in wide use for that many years? Tape–maybe. That’s the end of my list.

Damn. That’s a lot of angular momentum. Will I miss spinning disks when they’re gona entirely?

Hah. Guess.

  • There’s lots more Neanderthal in us than we previously thought. My knobby Neanderthal head is poking me in my conical ribcage…
  • Google just sold Motorola to Lenovo, but will be keeping the Motorola skunkworks.
  • Saturation radio advertising in the early 70s has left their jingle stuck in the far corners of my head, but I never actually tasted Zapple cinnamon-apple wine. Weird wines fascinate me (I stop well short of baby mice wine, thanks) and that sounds better than some of the gimmick wines I’ve tried in my life.
  • However, I did try Mateus and Lancers back in the day, both of which were handed out to all passengers on those noisy old Fokkers I used to ride between Chicago and Rochester MN when Carol was in grad school. Both still exist. I wonder if I have the will to buy one of each and see if those old golden memories were about the wine or the woman? (Three guesses. None of them count.)
  • So is it “assortive” mating, or “assortative” mating? I see both spellings online, but having internalized “preventive” I’m loath to endorse”assortative.”
  • A heads-up on something I’m investigating when time allows: Running the Atlantis word processor on Windows 7 fails the first time, but launches the Windows 7 Game Explorer module gameux.dll, which for some reason causes rundll32.exe to use about 50% of my CPU cycles thereafter. This problem arises with games, but Atlantis is not a game. The machine does not have a network connection, which seems key. Still poking at it, but if you’ve seen this problem and fixed it, do let me know how. I’m starting to think that there’s a game called “Atlantis” somewhere and that Game Explorer is looking for a network connection to “do something.” If there’s a way to carve Game Explorer out of Win7 without breaking anything else, that would be not only useful, but damned useful.
  • People in Colorado are already skinnier than people in other states. They may be about to become skinnier yet.
  • Another revelation from the Ministry of the Painfully Obvious: Political discussions damage Facebook relationships. Since a huge fraction of Facebook posts seem to be hatehurling anyway, this should surprise no one.
  • Perhaps a new way to look at the dichotomy: Weather is anecdotes. Climate is data.

The March of Computer Time

Jan 21st, 2014
by Jeff Duntemann.

Last night I turned in my chapter on programming–just think, all of software development summarized in 55 book pages!–and am gathering my thoughts on mass storage for the chapter I’ll begin later today or tomorrow. Again, if you haven’t seen me much lately that’s the reason.

Each of my chapters has begun with a historical perspective on that chapter’s computer technology topic. This has brought lots of things to mind that I haven’t thought about in years, like IBM cards, FORTRAN, punched tape, and Bernoulli Boxes. I still have the card deck from the first program I ever wrote, in the spring of 1970. (See above.) I did some work with paper tape as well in my COSMAC days, but whatever tape I kept has been hiding well. I’d love to get a scan of a length of ASR-33 style punched tape, or a length (8″ or so) of the tape itself to scan here. Doesn’t matter what’s on it as long as it’s not greasy or physically damaged. Contact me if you have some you could spare, or least scan.

Time marches on. I have a 10MB Bernoulli Box cafeteria tray cartridge–probably in a box somewhere with the paper tape–and an original 1983 Microsoft Mouse. Obsolescence doesn’t bother me as long as I can keep functionality. I had to buy a copy of Office 2007 to keep writing commercially, since Word 2000 doesn’t understand .docx files, and Atlantis doesn’t do annotation. Yup, time marches on.

It does. Right now we’re looking down the throat of something a little unprecedented: On April 9, Microsoft turns off security updates for Windows XP.Most of my nontechnical friends seem unaware of this, and my nerd friends have long since moved on to Win7 or 8. I’m in the middle: I’ve been using Win7 on my GX620 for about a year, and have a new Win7 Optiplex 780 on the shelf ready to be populated and configured when time allows. (I’ve done almost nothing but this book for what seems like–hell, has been!–months.) I’m about to take my quadcore in for a new sled-mounted SSD and Windows 7 Pro. The 780 will become Carol’s office machine. I will keep an SX270 XP machine basically forever, because it has pop-in drives for both 3.5″ floppies and Zip cartridges, some of which are piled in odd boxes here for no compelling reason other than they’re paid for. (Yes, most of them have probably gone to bitrot by now.) However, it will no longer be on my network, and will be powered up only as needed.

Here’s an interesting wrinkle that few people seem aware of: Win7 Professional comes with a special-purpose copy of VirtualPC, with a VM containing an instance of XP. (Win7 home does not.) I’m thinking that if I don’t enable the Ethernet connection to the XP VM, it doesn’t matter whether the instance gets security updates or not. I have some stuff here that won’t run on Win8, and possibly not on Win7 either. I can install it on my poor SX270 survivor, of course, but it will be interesting to see what limitations may exist on the XP VM. If something weird turns up in the VM, I can always revert to an archival image.

The real problem with this, of course, is that a lot of nontechnical people are still using ancient machines that won’t run Win7 ever. Only five or six years ago, I still saw Windows 95 on 486 machines owned by older people at my parish. I’ll bet there are plenty of doddering Pentia XP boxes with 512MB of RAM still crunching email and (maybe) Web, along with Office 97. What happens to them? They may well get pwned. On the other hand, I’ve seen several with updates turned off that aren’t pwned. How bad is the problem, really?

I’m sure nobody knows. Sometime this spring we’re going to find out. How many exploits are likely to be left in a 12-year-old codebase? There will be some. Not all exploits are the result of bad coding practices, though I’m sure plenty can be walked back to unbounded string functions in libc, which the C community just can’t seem to give up. XP’s security model is generally lousy, especially for people who don’t understand the implications of what they do, double-especially with Internet-facing apps. That being the case, how far does Microsoft’s responsibility extend? As big as they are, can’t they keep a few security fanatics on staff to fix the exploits that do appear?

I’m thinking that questions like this may soon be asked in the courts of law. We’ll see.

Anyway. I can fix things here, and in extended family. I do worry about nontechnical retirees at our church and elsewhere. When you’re 80, a 12-year-old OS may not seem like any kind of problem, and those on fixed incomes may not feel like $500 for a new box is worthwhile to solve a problem that remains hypothetical. (Hell, my 4Runner is older than XP.) Those of us who remember Y2K hysteria can be forgiven for a strong dose of skepticism. I expect pwnage. There’s pwnage today. The only question is how bad it gets, and how much bad PR it will earn Microsoft. My prediction: If it gets bad enough, and the lawsuits get thick enough, the updates will return.

Pass the popcorn and dig your 3-D glasses out of the drawer. This is gonna be good.

SurgeryAllergyLabel - 01-16-2014.jpg

Carol’s home and sound asleep upstairs, after having her right foot fixed late this morning. She won’t be walking unassisted for a couple of weeks. No problem; she has a knee scooter, crutches, and me. Oh, and practice: Having had her left foot and ankle repaired on Halloween, we both know the drill. Time and love will do the job. Our nephew Matt and his beautiful fiancee Justine will marry this coming August, and damn, there will be dancing.

The surgery RN asked Carol about her allergies, and Carol wore the fire-engine red badge above during surgery. No cats or mangoes were encountered, nor any other difficulty. The surgeon came out to the waiting room to let me know all was well, with an X-ray of Carol’s foot in his hand. He explained the pins and the bones and other things that lie far outside my core competence. My main question was simple: Is my forever girlfriend all right? The answer was all I needed to know: She is.

The Pack is over at Grandma Jimi’s getting washed and groomed and will then spend the night, so for now peace reigns at Phage House on Stanwell. When we dropped them off, Jimi gave us a crockpot full of home-made chicken soup. There’s most of a very good pork shoulder in the fridge and another in the freezer when we finish that. I laid in a couple of bags of Costco torta rolls and a fresh quarter wheel of Stilton cheese. We’re short on diet ginger ale, but the wine rack is full. If there’s any hunger in this house in the next week or so, it’ll be the sort of hunger where most of TV is from. (Especially The Weather Channel, more on which when time allows.)

Not much to report, which is good. I’m currently writing a summary of coding GUI apps in Python using Tkinter, followed by a summary of coding GUI apps with FreePascal and Lazarus. Then this interminable chapter will be over.

More tomorrow.

Yearwander

Jan 4th, 2014

Wow. Somehow it got to be a whole new year when I wasn’t quite looking. I’m not unhappy to be shut of 2013, and as usual, I have high hopes for this year to be better. The last of our parents has been released from her suffering, and while I miss them all (especially my father, who died 36 years ago) my idiosyncratic understanding of Catholic theology suggests that they’re all in better shape than I am right now.

Which isn’t to say I’m in bad shape. I had a couple of health problems this year, but nothing horrible. I’ve been able to get my abdominal fat down to almost nothing, and weigh just eight pounds more than I did when I was 24. It still puzzles me just a bit, but I lost that weight by eating more fat. I’ll tell you with confidence that butter makes almost everything taste better except corn flakes.

I scored an interesting if slightly peculiar writing gig this year. It’s been an immense amount of work, not so much in the writing as in the learning. I’ve never done a book–or part of one–with this broad a scope. I’ve touched on a lot of technologies in my career, but touching isn’t understanding, and understanding is the critical path to explaining. I’ve written code in Python and C and ARMv6 assembly. I practically buried myself in ARM doc for most of two months. That felt good in the way you feel good after walking fifteen miles…once you’ve allowed three or four days for the smoke to clear. I now know a great deal more about virtual memory, cache, and memory management units than I might have just touching on things in my usual fashion. Curiosity is an itch. Autodidaction is a systematic itch. And to be systematic, you need deadlines. Trust me on that.

No, I still can’t tell you about the book. It’s going to be late for reasons that aren’t clear even to me. When the embargo breaks, you’ll hear it whereverthehell you are, whether you have an Internet connection or not.

Every year has some bummers. The ACA did us out of a health insurance plan that we liked, but at least in our case it wasn’t cancelled on the spot. We have some time to figure out where we can get a comparable plan, if one exists. (One may not.) It could end up costing us a quarter of our income or more, and we may lose relationships with physicians we’ve known for ten years. I’ll just be called evil for complaining, so I won’t. Anger is the sign of a weak mind, after all. I think one of my correspondents whose insurance was cancelled without warning summed it up in an interesting way: “I’m not going to get angry. I’m going to get even.”

It’s snowing like hell as I write. I would have posted a photo, but as most of you are staring out the window at snow this week (in some places a great deal of it) I doubt it would have been especially interesting. Besides, a couple of hours ago, I could have just said: Imagine yourself inside a ping-pong ball. Open your eyes. In truth, the weather hasn’t been all that bad. The global climate, in fact, has been remarkably benign considering all the dire predictions of the past ten or twelve years, at least once you look at actual stats and not anecdotes or GIGO models. Science works. Back in 2007, Al Gore himself told us that we would have an ice-free arctic by 2013. (Then again, he also said that a couple of kilometers under our feet it was millions of degrees…talk about global warming!) I love the scientific method. You predict, you test, and then you learn something. Sure, I believe in global warming. I’m still unconvinced that it’s entirely a bad thing. (I remember the ’70s. I also remember Arizona.)

I’ve also been doing some experimental research on the psychology of people who jump up and start frothing at the mouth like maniacs the instant they read something somewhere (anywhere!) that conflicts with their tribe’s narrative. That research is ongoing.

I’ve discovered a lot of good things, albeit small ones: Stilton cheese pairs with Middle Sister Rebel Red. Who knew? Python is much better than I remember it, TCL, alas, much worse. And Tkinter, wow. You’re not going to spin a GUI that fast or that easily in C. Green Mountain Coffee Island Coconut beats all, at least all you can get in a K-cup. Carol and I are dunking good bread in good olive oil again, now that Venice Olive Oil Company has a retail shop in Colorado Springs.

Time to go up and start cooking supper. We’re out of egg nog but my Lionel trains are still running. I don’t care if it looks like a ping-pong ball outside. I have my wife, my dogs, my junkbox, and a head that still works more or less as intended. Happy new year to all. Life is good, and getting better. Trust me on that too.
