I feel like I owe it to my readers to disclose a few things, due to the events of recent weeks raising a few questions in some people’s minds.

PC slumming

Dave Farquhar General , , , , ,

Slumming. I spent a portion of the day Saturday messing around with an old 486-133. The DCE at church asked me what it would take to build an intranet. I said an old PC. So he handed me an old 486-133. I can’t shake this machine. I built this computer back in 1994 or so for a law firm. I performed several upgrades on it, including the 133 MHz upgrade (it started out as either a 33 or a 66, not sure which). Three years ago or so, when it was obsolete, the firm called me and asked me to haul it away. I asked my church if they wanted it. They did.
This 486-133 is available because it lost its old job to an old Pentium-200 I scrounged up and rebuilt. Trying to run anything more than a simple fileserver is pushing the limits of this machine. But I like pushing the limits. So I decided to see what I could do with it. I took it home and opened it up. Hmm, It had a 72-pin and 4 30-pin SIMM sockets free. I tried out an old 8-meg SIMM I had. It didn’t like it. I thought I remembered seeing some old 30-pin SIMMs laying around…. I found some. I put them in. It counted to 20. Nice.

I tried out a 420-meg HD I’d salvaged from somewhere or another. The system detected it as an 850. Curious. I disconnected the true-blue 850 in the box. It still detected the 420 as an 850. Mislabeled, perhaps? I’ve seen stranger things. So I started to install Linux. I was able to partition the drive, but then it emitted a click-o’-death when Debian tried to initialize the swap partition. So I did what I should have done in the first place. I took off the cover. Next time someone asks me how a hard drive works, I’ll be able to show them. So the 850 flew solo.

Then I added the last from a stash of old DEC Etherworks 3 NICs I had (one of my employer’s clients handed me a bag of them months ago and said, “Donate them to your cause.” I’ve been giving them away one by one ever since) and installed Debian 2.2. Debian installed a lot slower than it does on a Pentium.

I installed Squishdot. I found it could be tweaked to give a very professional look. I also found it horribly confusing because it’s so unlike any other content management tool I’ve used. I messed around with it for a long while, but it was slow. Really slow.

I tried some alternative kernels. No improvement to speak of. I added the noatime parameter to the root partition’s entry in /etc/fstab. That helped a little.

But still, it was swapping out and the CPU was topping out as well. The homepage was taking 18 seconds to load. That’s not good.

Apache serves up static Web pages just fine–no slower than any other computer. But this dynamic stuff might just be too much.

So as a last resort, I compiled a lo-fat kernel. I took 2.2.19 and basically answered no to all but the absolute essentials. Mouse? Forget it. I was half-tempted to leave out floppy support, but that would make maintenance a bit more difficult.

It’s unfortunate that I don’t have any matching pairs of SIMMs laying around. Otherwise I’d swap the board out for a Pentium-75. I’ve got a couple of ancient Socket 5 boards laying around, and at least one Pentium-75 CPU. I’ve got two mismatched 4s, but that’s asking for instability, and I’m not sure if a P75 with 8 megs is any improvement over a 486-133 with 20.

Compiles take a couple of hours. I really should have just compiled a .deb package on a faster machine and moved it over. It seems hard to believe that it wasn’t terribly long ago that a 486 was a perfectly workable computer, and now it feels like a PC/XT. But the 486’s heyday was 10 years ago now. And 20 years ago, the PC/XT wasn’t on the market yet, though its direct ancestor, the IBM PC, was. So I guess it’s not too unreasonable to regard this 486-133 as the Turbo XT of today.

Back again….

That new job. I started my transition on Tuesday. Tuesday was my best single day at work in more than four years. For the record, I started my professional career in March 1997–so I haven’t been working much more than four years.
I picked up the laptop I’ll be using for my new job yesterday. It’s a Micron Transport LT, a short-lived lightweight. It was a good machine, but when Micron sold off its PC division, it got axed. Its replacement, the Micron Transport XT (a name that still makes me chuckle; old-timers will know why), is bigger and heavier. It has a bigger screen, which is worth the extra weight, but I like the small size of the LT. It’s a 700 MHz machine, so even though it’s about six months old, it’s no slouch.

I installed Windows 2000 and Debian 2.2 on it. Of course I quickly made Debian into a hybrid because I wanted to run packages like Galeon that aren’t available for 2.2. Yeah, so it hasn’t been deemed stable yet. The most bleeding-edge Linux distros I’ve ever seen are more stable than anything Microsoft’s ever slapped its name on, with the possible exception of MS-DOS 5.0. Even Debian-Unstable is more conservative than Mandrake, so having bits of Debian-Unstable on my PC doesn’t bother me in the least.

I got to dabble in my new position yesterday, even though I was officially doing my old job. There was a server to deploy, and I was reasonably idle, so naturally I worked on the server.

They should be ashamed of themselves. After the Sept. 11 attacks, the president of my church body, Dr. Jerry Kieschnick, and the president of the Atlantic district, Dr. David Benke, committed the unpardonable sin of praying with people who are members of church bodies other than the LCMS. They now face expulsion from the church body.

This account from a St. Louis television station is a fair summary of the events.

What that account doesn’t tell you is that the First Vice President of the LCMS, who would take office if the presidency were vacated, was widely considered a political enemy of Dr. Kieschnick before the two of them took office early this fall. Dr. Kieschnick is considered a progressive, while his would-be successor is a hard-line conservative. I don’t know anything about Oberdieck, but I do know that Lebanon, Mo. isn’t exactly a hotbed of progressivism.

KSDK oversimplified Oberdieck’s reasoning slightly. Oberdieck believes that Drs. Kieschnick and Benke’s actions imply that all religions are equal, and he objects to that implication. However, if you talk to Dr. Kieschnick, the last thing he’ll tell you is that all religions are equal. He’ll agree wholeheartedly with Oberdieck’s statement that there’s only one way to God–that’s Jesus Christ, in case you’re wondering what I’m talking about–and that it should be followed strictly. The motivation behind the two mens’ actions in NYC in September was to extend a hand, to tell people that the LCMS cares about what happens to them and wants to help them.

The overwhelming majority of Lutherans in this country know and understand that.

This is a political play, pure and simple. It’s just like what the Republicans tried to do to Clinton with Whitewater and what the Democrats tried to do with Gingrich after he became speaker.

And it may undermine the current president’s credibility. What it certainly will do is leave a bad taste in people’s mouth. In a month or two months or five years, people won’t remember these specifics anymore. What they will remember is having a bad taste in their mouth about the LCMS, or worse yet, about Christianity as a whole. The immortal Someone Else will have to work hard to overcome those feelings. Sometimes Someone Else will succeed. Inevitably, sometimes Someone Else will fail, and the hurt will continue. But that doesn’t matter, because it’s Someone Else’s problem, not theirs.

I hope Oberdieck and his allies are happy.

When I was 10, it was a very good year. Well, not really, but I can’t pass up the obvious Sinatra reference. Bear with me.

I had a conversation the other day with Gatermann that I thought was pretty funny. Tom sells cameras, and he’s got this Mac-o-phile who comes in and always talks about how great his Mac is. But his Mac is really a five-year-old Power Computing Mac clone, and he does all his day-to-day work on PCs. He always talks about how much better his Mac is than a PC, but he never uses it.

At any rate, Tom’s got another regular who’s in the market for a computer. This guy’s trying to talk him into an iMac or a Cube or something, but he’s torn. It just seems a PC gives you more bang for the buck, he thinks. Tom told him to look into an Athlon-based system.

I told Tom to tell him to go to micronpc.com and configure a Micron Millenia with an Athlon, since Micron does the best job of any direct build-to-order vendor I know of not giving you cut-down components, and their prices are generally really good. Tom snickered. I asked if he had a computer.

“He has a PCjr.”

I hit the table with both hands and nearly stood up. “He’s got what?” Tom didn’t even really know what a PCjr is, other than it’s really old.

“A single-floppy wannabe IBM XT, with 128K of RAM,” I told him. “Vintage 1984.”

Still snickering, Tom said he told this guy that if he did decide to upgrade, he knew of a guy (me) who might be interested in buying the PCjr.

I laughed. Well, let’s see. I’ve got this PC/AT I’ll be fixing up. I’ve got a PS/1 I can rebuild. And I’ve got a still-useful IBM computer that also happens to be unmodified, a ThinkPad. So since this is IBM Central anyway, why not? Then I remembered why not: I don’t have that kind of space. I’d have to put it in my kitchen, but there’s not really any room for it there either. Any computers I bring in at this point have to serve some function, and making people wonder aloud, “Why on earth do you have one of those!?” doesn’t count.

I did ask Tom a question. If this guy had a PCjr, why’s there any question what to get? He got 16 years out of a wannabe PC, so why not just get a PC again? Besides, I can give him a 5.25″ drive and install it so he can read his existing disks if he wants.

And yes, that’s all I’ve got. Hopefully I’ll have some energy for tomorrow.

Bottom fishing. I was over at my church’s sister congregation Monday night, looking over their computer situation. They just got a grant to build a lab, so they asked me to come assess what they have and tell them how to most wisely spend the money they got.

If I were buying all new, I’d be torn. I like the idea of the Compaq iPAQ. It’s $499, it’s all integrated, it’s powerful enough (once you up the memory), comes with Windows 2000, and someone else built it. I can just get seven of them, plug them into a hub, set one up properly, clone it to the rest, and be done with it. It’s a business-class machine from a proven maker.

On the other hand, Compaq Presarios start at $399 and include all the software they need. I’d have to get NICs for them, but that’s $40. Memory’s another $60. So for the cost of the iPAQ, I get similar hardware plus Win98, Word, and Works. But it’s consumer-grade hardware and I’m not impressed with Presarios. I’d really rather have iPAQs with Windows 2000 and StarOffice, frankly. I think they’re better machines. (And there’s probably money to buy the software we need.)

But what about what they have? It’s truly a mixed bag. Mostly a mixed bag of junk. There’s an XT in their room, along with one of the first Compaq 386s. The Compaq is junk. I’m trying to find an appropriate word for the XT. There are a whole bunch of LPX form-factor 386SXs, some Dell and Compaq, others Packard Bell. Junk. There are three Compaq Proliant servers, 486-based, decked out with SCSI drives. Rugged and reliable, I could turn one of them into a Linux gateway, and put Samba on another for use for file serving and authentication. I thought I saw a Compaq Deskpro 486/33. Reliable, but not very useful these days. And there are three ATs: one a 386 and two Pentium-75s, one of which works. The other gives beep codes, so probably either the memory or video’s shot. All in all, 90% of it’s useless, and none of it’s even worthy of being called a museum piece.

Normally I’d say junk it all, maybe keep one of the Proliants and the working Pentium-75. But in light of those $29 Soyo BAT Celeron motherboards… Do the math. The board’s $29. A Celeron is $50. A 128-meg stick is $60. I can probably salvage the video cards, except for the one in the 386. So add a video card, say, $35. Of course I can salvage everything else I need from that big stack of obsolete stuff. So for about $150 each after shipping, I can have two Celerons. For another $180, I could have a third.

Sounds good on paper, but a new Presario costs $399, has more than $220 worth of software, and is covered under warranty. Compaq’s not my favorite computer company, but I don’t really want to be their computer company.

Those $29 Soyo boards are good enough for me. That’s why I ordered two. So I’ll get one final tour of duty out of my souped-up IBM PC/AT, which has done time as a 286 of course, a 386DX-40, a Pentium-75, and a Cyrix 6×86-166. Sick thought: If I end up putting a Celeron-500 in it (I haven’t decided what CPU it gets yet), that AT could be my fastest computer again.

But what makes sense for me often doesn’t make sense elsewhere. And I guess that’s why I write books and magazine articles–sometimes I can figure out when and why that is.

A disk tool that could save your bacon someday. You find all kinds of cool stuff in online forums, let me tell you. I probably find one or two gems a week, but for me, that’s worth it. MBRWORK allows you to play around with partitions, and can even allow you to restore deleted partitions. It’ll also remove those disk overlay programs for you, which is great–the only sure way I could ever get rid of them was to low-level format the drive, which takes forever and is destructive, of course. You can find it at www.terabyteunlimited.com . You can find some brief documentation and screenshots online at www.webdev.net/orca/mbrwork.htm . Download this and keep it in a safe place.

I don’t think do-it-yourself data recovery is something anyone wants to get good at, but it’s usually better than paying someone to do it.
