  1. Re:Bias? on Ubiquiti Announces RouterStation Challenge Winners · · Score: 1

    Which entry are you claiming was produced by Ubiquiti? It looks to me like none of the three winning entries are from them. PyCI is by Dan McDougall, NETSHe is by Stanislav Korsakov, and OpenNET is by Derek Conniffe Hazel Lodge. I don't seen any obvious evidence that any of them work for Ubiquiti.

  2. Nice hardware too on Ubiquiti Announces RouterStation Challenge Winners · · Score: 1
    I just was responsible for setting up routing for a microwave network between three college campuses on separate islands. The inter-island links used Motorola (formerly Orthogon) PTP600 radios. I used six ImageStream Rebel routers (which run Linux) for the moderately high performance routing, and four Linksys WRT54GL routers running OpenWRT for less performance-critical areas. I specified the WRT54GL because it is quite inexpensive, but it also has barely enough flash memory to do what was required. If I had known about the RouterStation Pro, and been able to buy them with a suitable case (rather than just a circuit board), it would have been absolutely ideal for the project. I'll probably use the RouterStation Pro for future clients, or for system expansion with existing clients.

    PyCI looks very nice too, but I'll probably mostly stick with the CLI since I'm comfortable with it. Although I did provide training for the client's IT staff on how to install and configure OpenWRT for their specific requirements, the general idea is that it shouldn't need any configuration changes on a routine basis.

    It *is* bundling, because Office Starter isn't available in any way other than buying it bundled with the computer. A laptop power supply can be purchased separately.

    Look at the history of anti-bundling legislation in the EU; most of the cases have NOTHING to do with whether a product is "integral to the OS", because most of the cases don't even involve an OS.

    Probably can't get MS to bundle OpenOffice, but maybe it's possible to get some of the major PC makers (e.g., HP, Dell, etc.) to bundle OpenOffice on PCs they sell? They certainly add plenty of craplets to their PCs, so why not add something actually useful to their customers?

    The drives already do that internally. By the time they're reporting errors, bad things are happening, and it really IS time to replace the drive. Anyhow, drives are inexpensive. It's more cost effective to replace them than to spend a lot of time screwing around with them.

  13. Re:9V != 18W on Teenager Invents Cheap Solar Panel From Human Hair · · Score: 5, Informative
    I would be quite surprised. If you buy a 9V alkaline battery at the drugstore, take it home, and put a 4.5 ohm resistor across it, you will NOT get 2A of current flowing through the resistor. The battery can supply 9V at a lower current, but with a load with too low a resistance, the battery voltage will drop.

    The same principle applies to any other non-ideal voltage source. A solar panel that produces 9V open circuit or at some low current is not necessarily able to produce 9V at 2A.

  14. typing class in jr high in late 1970s on The Case For Mandatory Touch-Typing In High School · · Score: 2, Insightful
    In the late 1970s I took a typing class in junior high school. Boys were actually discouraged from taking typing, so there were only a few other boys in the class. Despite the speed and accuracy requirements to pass the class being quite low, I barely passed, and the teacher advised me that I should never take a job requiring typing skills.

    I've been employed as a programmer almost continuously since that time; I did contract programming work while I was in high school. Learning to touch type made me much more productive than I'd been before the class. Over the years my typing speed has dramatically improved; the last time I checked it was over 100 wpm, though my accuracy hasn't improved nearly as much.

    I think any student that doesn't take a typing class in junior high or high school is doing himself or herself quite a disservice. It's a valuable skill even for someone that doesn't need it for a job. I suspect that it's probably easier to learn typing the earlier you do it.

  20. Re:You already know where to go for disks.... on Getting a Classic PC Working After 25 Years? · · Score: 3, Informative
    Double density 5.25 inch disks work just fine at single density.

    Double density (AKA "standard density" or 360K) cannot reliably be formatted for high density (1.2M) use, or vice versa, because the coercivity of the media is significantly different.

    IBM-compatible PCs have never used single density as a standard disk format, and many IBM-compatible PCs can't actually deal with single density, though some can. The first disk drives shipped on PCs were single sided, though IBM switched to double sided fairly early on. The format progression for media on the PC, AT, PS/2, and compatibles was:

    1. 160K (5.25 inch, 40 track, double density, 8 sectors per track, single sided, 300 RPM), first supported by IBM DOS 1.0
    2. 320K (5.25 inch, 40 track, DD, 9 SPT, double sided, 360 RPM), first supported by IBM DOS 1.1
    3. 180K (5.25 inch, 40 track, DD, 9 SPT, SS, 300 RPM), first supported by IBM DOS 2.0
    4. 360K (5.25 inch, 40 track, DD, 9 SPT, double sided, 300 RPM), first supported by IBM DOS 2.0
    5. 1.2M (5.25 inch, 80 track, high density, 15 SPT, DS, 360 RPM), first supported by IBM DOS 3.0
    6. 720K (3.5 inch, 80 track, DD, 9 SPT, double sided, 360 RPM), first supported by IBM DOS 3.2
    7. 1440K (3.5 inch, 80 track, HD, 18 SPT, DS, 360 RPM), first supported by IBM DOS 3.3

    There were, of course, other formats not supported by IBM DOS, but used by other vendors or other software.

  24. knows how to change with the times on Kodak Kills Kodachrome · · Score: 2, Interesting

    At least the analog photography industry knows how to change with the times.

    That's like saying that the buggy whip industry knew how to change with the times.

    What they know is that Kodachrome isn't selling as well as it used to, therefore it's not worthwhile for them to manufacture it any more. It's not due to any extreme cleverness or long term strategic planning on their part.

    This is basically the same way that Intel got out of the DRAM business. If you read Grove's book Only the Paranoid Survive, he describes how Intel avoided losing their shirts in the DRAM wars not by being extremely clever in forseeing that the DRAM market was going to become brutally competitive, but by their standard business planning based on costs of wafer starts and profits of various kinds of products. When DRAM became less profitable, fewer wafer starts were allocated to DRAM and more allocated to other products, eventually to the point that they were making almost no DRAM. They realized what had happened AFTER the fact.
