Gee, just the other day on a fresh linux install (redhat 9), I had an instance of rpm hang up. Couldn't kill it, even with kill -9. Couldn't run any other instances of rpm either. strace showed that it was hung up in a futex() system call. man futex didn't show anything, I didn't have time to debug it, so had to reboot it.
Even on my 5500, I don't have that problem. I did a bit of work on the rom image so that it uses the SD card as a direct replacement for the internal volital ramdisk. Then I shrunk down the ramdisk size so that I have nearly the full 64meg of memory available for system ram.
Lately, I've even set up a dual-boot system, where I can boot up normally, or boot up using the SD card mounted on/home (instead of the ramdisk), or use the SD as root -- which lets me run things like OpenZaurus and Debian completely of my 256meg SD card. Write speed on the SD is slow, but I took care of that by tweeking the kernel. Apparently, Sharp added a patch to force filesystem to be mounted sync (even if you use "-o async" with the mount command). After turnning off "CONFIG_FS_SYNC" in the.config file and recompiling the kernel, the SD card feels as fast as the ramdisk.
I did the same thing. Told the sales guy to get his manager, and explained that I was going to buy a laptop that day, and the store that would get my business is the one that would let me verify the laptop with my boot cd. I also hinted that I liked their extended warranty options. Dollar signs lit up in the sales manager's eyes, he let me boot with Knoppix, and I left with a laptop, a grand less cash, and without the extended service plan:-)
Well, at least My "home" office doesn't have a janitor (uh, except for me), no security guard either (unless you count the lady that lives down the street, she notices _everything_. Also, since I'm well into my 30's, and the youngest in my family, then Mom no longer has a 16-year old kid wondering the halls.
It is NOT a limition of DOS, it is a limitation of the original IBM PC HARDWARE. You see, in 1981, the IBM PC was built around the Intel 8088 CPU, which could address 1024k of memory. The upper 384k was reserved by the hardware for the system bios, video ram, video bios, and any other board that needed memory-mapped I/O. Even the 80286 CPU had the 1024K limitation when it ran in "real" (8086/8088) mode.
Your operating system version or the browser you are using does not support this feature. Supported configurations include Microsoft Windows running Microsoft Internet Explorer 5.5 or greater.
So, I guess I can't purchase a linux machine without using windows:-(
I'd like to see, just for kicks, a IDE drive hooked up to a scsi controller via an Acard ide-scsi bridge. Is the speed of scsi mostly from the controller, or from the drive mechanics?
>... can pass pointers to all sorts of complex structures.
A command line can also point to objects that contain complex structures. These objects are called "files". For example, with the tar command, you can pass it the name of a file containing an input list of files to add to the tarfile.
I've strugled with this question myself. I've got a Zaurus 5500, and love it for what I use it for, but a Palm seems to make a better PDA. So, I've come to the conclusion that a Linux handheld device isn't a PDA, but a small-sized computer. So, a Linux pda makes for a good platform if you are a unix developer who needs to write custom hand-held software. Also, while there are a bunch of Palm apps out there, not many are free. It's not that I have to have everything for free, but often times an app doesn't quite work the way I want, and I like to be able to tweek them a bit. An example, I found a good TI-85 calculator emulator, but the buttons looked awful. A bit of messing around with the xpm definitions, and now the button colors are defined in the config file. This is the kind of stuff that you just can't do with non-free apps that you find on Palm or PocketPC.
As for what I use mine for: * Web lookups (i.e., looking up items in Internet phone books, TV listings, dictionary definitions) * Other web browsing when it wouldn't due to to carry a laptop (meetings, nature's call, etc) * Custom PIM app -- I wrote a web-based app which allows me to organize data and meeting notes in a unique way that suites me. On my Zaurus, I've got a version of the app served up by a local web server. Whenever I'm within wireless range, a background task automatically keeps the local database synced with the one on my server. (Once I perfect it, I'll put it up on sourceforge). * Entertainment -- with a wireless card in the Zaurus, and one in my laptop, I can stream movies and music to the kids in the car served up by my laptop which I use for navigation. It also runs Mame.
Basically, the main thing that the hybrid does for you is it lets the car re-capture the energy wasted in breaking, and apply that to taking off again. Which is why the Honda gets better milage in city than highway (most cars do better on highway milage).
You mentioned that you want to use the usb drive as a replacement for a floppy. What about using your cdrw drive instead? At a buck a pop, cdrw's are much cheaper than flash storage, and with udf filesystem, you can random write to them. If size is a problem, I've seen those 210 meg mini cdr/cdrw's at varisous computer shows (although I don't understand why they cost more than a full size cd). Get a bunch of those, and if you need cases, you can get Gamecube cases (same size disk), and they'll fit in your shirt pocket.
I remember reading about a study where groups of college students were asked to debug the same program, but each group was given a different indentation level. There was a dramatic decrease in time to debug when the level was increased, up to 4 spaces, but after that it hit diminishing returns. So, 4 is often considered optimum.

Why is it that everybody continues to equate [M|G]Hz with CPU speed? It's only a component. Those old 4.77Mhz boxes took several Hz to complete a single instruction. A modern Intel or AMD chip runs several instructions per cycle. So therefore, a current top of the line system actually runs 3-5 thousand times faster than the original PC/XT. (But it still takes a couple to 3 minutes or so to boot up.)
> So you're advocating security through obscurity?
Well, I think everyone advocates this. If you don't beleive in the obscurity thing, then tell me, what is your credit card number, bank account, ATM pin code, Slashdot password, etc..., or would you rather keep them secure by making them obscure?
Actually, I've got an alternative commercial model: An area (or national) ISP offers (and bills) it's customers hotspot access. Anyone who owns a hotspot can sign a deal with the ISP (or multiple ISPs). When the ISP signs on and authenticates via a participating hotspot, the hotspot providor then bills the ISP for the access. The authentication and accounting aspects can be handled with existing protocols, but it may be easier to impliment with IPv6 (roaming IP's without tunnels, encryption at the link level, etc...)

Check out tomshardware.com, they have an article on manufactures replacement policies for burned out pixels. Basically, the policies are all accross the board. Also, they make a distinction between an "unlit" pixel (black), and a "stuck" pixel (always on). Personally, I can put up with an unlit pixel at the edge of a screen, but I had a laptop once that had a couple of red pixels towards the middle, and it drove me bonkers.
Uh, it's not that they don't read their page, it's that the stories are actually entered into the system much earlier, along with a "release time". It could be that Taco entered his story before Hemos, but entered a later release time.
However, since they have already distributed Linux under the GPL, they are in fact granting everyone rights themselves under the GPL. Therefore, they loose the right to sue for any patent infingement contained in any code they have distributed. You can't give someone a non-revokable right in a contract, and later try to revoke that right.
One digital phone I'm really satisfied is Nextel, which uses the IDEN protocol. It's basically the same as TDMA, with the 2-way radio feature added in. With the 2way radio, you have a number of benefits -- much cheaper (they are billed out at 1/10 second intervals), and you don't get tied up in a long conversation with someone when you just need a bit of info. That is, since communication with the radio feature is half duplex, the person your conversing with will tend to give you the facts quickly, then release the key in order to get the reply. Whereas, if you call someone, it tends to turn into a long useless conversation. Therefore, it's about as efficient as doing SMS messages.
Slashdot Mirror
If you had to reload from hard drives, then assuming your data transfer rate is 20 meg per second, then it would take about 62.5 hours to populate.

Terraforming would still be do-able, but the results won't last very long. Of course, "long" can be measured in geological terms.
