Noticed an ambulance parked out in front of Fry’s earlier today. On my way in, I passed two people who were talking about it:
“That’s kind of disturbing.”
“Sure, ‘Shop ’till you drop,’ but…”
One of those moments where you know you shouldn’t laugh, but it somehow manages to be funny anyway.
We were at the grocery store earlier today, and Katie was grumbling about the stylus-only touch screens they had for entering a PIN. Unlike actual keypads, you can’t hide the number you’re entering, because you have to move that stylus around instead of 10-keying it in.
On one hand, a touch screen with a stylus is great for visual feedback and for collecting signatures, because the store can keep things on file digitally instead of or in addition to a paper copy. And once you’ve got that, it’s reasonable to drop the keypad, since you can simulate it in the touch screen. But unless it can react as quickly as actual buttons, and react to fingers instead of a stylus, it can’t completely replace the way a keypad is actually used.
An even better example is checkout line at Fry’s. Continue reading
I’ve been thinking about adding memory to the PowerBook for a while now, and for various other reasons we ended up at Fry’s last night. I figured, we’re here anyway, why not at least price the RAM?
Well, here’s a big fragging “Why Not:” I couldn’t remember the exact specs required. There was, however, a chart listing various laptop models, and the employees could look up requirements by model in the computer. The problem there was that I knew it as “the new 12″ PowerBook G4,” not as “Model A1010,” so they ended up (as near as I can tell) pulling up the specs for last year’s PowerBook (the 1 GHz instead of the 1.33 GHz). Naturally, the two models use different kinds of RAM.
When we got home last night, I cracked open the manual to compare the specs. Tonight, I waded through the Fry’s return line, and this time I brought the manual along — as I’d intended to do in the first place.
Everything went smoothly except for one glitch. The memory slot is covered by a panel with four size #0 Phillips head screws. I do have a size #0 screwdriver, and three of the screws came out easily. One of them refused to move, and the head ended up getting stripped somewhat. Eventually I was able to get it.
So, now the laptop has gone from having the smallest amount of memory at 256 MB (barring the ancient Mac clone in the closet) to having the most memory of all our computers at 1.25 GB.
On Friday I reinstalled Red Hat 9 on my computer. On Saturday I figured out why I couldn’t build Dillo on the virtual Conectiva system (the only reason I tried to install the real thing). On Monday I made a remark on the Dillo mailing list that, after trashing the system trying to install Conectiva, “unless/until I can set up a spare system solely for trying things out, anything else… will run under User-Mode Linux.”
And that got me thinking.
A spare system wouldn’t need to be elaborate. I wouldn’t be playing games on it. I wouldn’t be doing graphics work on it. I wouldn’t even be doing web development, word processing, or checking my email. Most of the time it wouldn’t even be running – just when I wanted to try something new, or when a new release of Dillo came out and needed RPMs. And since I have a spare KVM switch, I’d only need to find space for the case, and wouldn’t need to worry about a monitor.
I’ve mentioned before that I’ve upgraded my computer piece-by-piece since 1994. Well, when you do that, you end up with a lot of spare parts left over. Sure, they’re older, slower, smaller, etc. than what you’ve got now, but if they worked when you took them out, they probably still work now. I’ve been meaning to go through all the boxes, cards, drives etc. and get rid of things I don’t need anymore, but I’d never gotten around to it. Well, on Monday I finally had motivation.
I went through looking for parts I could use to put together a spare, expendable system – one where it wouldn’t matter if the entire hard disk got wiped. I found three hard drives (two of them too small to be useful), several sticks of RAM, network and video cards, and a motherboard and a CPU that wouldn’t fit together. That left: a case, a CD-ROM, and either a CPU to go with the motherboard, or a motherboard to go with the CPU.

It turned out my boss was getting ready to throw out some old equipment, including a huge mega-tower with a 450 MHz K6-2. The motherboard I have used to hold a K6-2. (Where it is now, I have no idea – I don’t think it’s the one I fried, especially since the motherboard seems to work.) So now I had a processor. My parents had recently replaced an extremely flaky computer, so I got a CD-ROM from that. Then I went to Fry’s and picked up a $30 case and $13 floppy drive.
That’s right: I have just built a $43 computer.
Somewhere in this whole process, Katie came up with the name “Red Shirt Linux.” And while it’s mostly going to be SuSE, Conectiva, and Mandrake, the name fits.
Preliminary tryouts look promising: All the hardware works, I was able to see old data on the hard disk before I repartitioned it, I could boot tomsrtbt off of a floppy and mess around under that. I tried Conectiva first, and it failed, but I think I’ve got a bad install CD. (The UML system I built from it has network problems, and the copy I installed on Ghostwheel is what trashed my partition table, so it doesn’t surprise me that it had problems here.) I’ll run a thorough memory test overnight just to make sure, but it looks like I’ve got a PC I can mess around with without risking any data!
We have a “yours, mine and ours” set of computers at home. My system started out as a Compaq Presario in 1994 and has been upgraded piecemeal over the past decade, Katie replaced her Power Mac with a G4 last year, and we picked up an eMachine to use as a dial-up server when we moved in together. (I was going to cobble something together out of the leftover bits from my computer, but it was cheap and saved me the effort of figuring out what was working and what needed to be replaced. Plus it gave us an extra Windows system.)
I’ve been dual-booting Linux and Windows for about 5 years, and spent most of my last year in college using Linux almost exclusively. (Student housing with Ethernet. Having worked in a college computer lab for several years, I didn’t trust Windows 95 to be safe on the network.) Well, a few months after we got the eMachine, hardware problems corrupted my Windows installation. I didn’t want to “borrow” a Windows 98 install CD, I didn’t want to buy Windows Me (piece of ****), Windows 2000 was too expensive, and I really didn’t want the licensing nightmare that is XP. So I delayed, using Linux exclusively, and eventually came to the conclusion I didn’t need to reinstall Windows at all.
Unfortunately, there are very few commercial games written for Linux. Now I’m not much of a gamer, but I do enjoy RPGs, turn-based strategy, and the occasional FPS, and No Windows meant No Might and Magic. Continue reading
