  1. Japanese Perl on English Language And Its Effect On Programming? · · Score: 5
    Maybe Perl in Japanese would let you create its own characters out of existing ones, then use the new characters in the programs. And you think Perl is compact and hard to read now.

    Of course, the opposite would happen with German Perl. You'd create new words by concatenating existing ones, so you'd have a word 4,000 characters long which would do everything related to a specific task -- change one of the component phrases and the new word does something related yet different.

    Or if you need encrypted storage (rather than communication) you'll simply carry your 200 terabytes of secret data on your keyring. The hard part will be having a keyboard and display which you know is secure. There's no such thing as a little paranoia...

  5. Could I have the old envelope please... on GNOME, Security, Linux, and Cable Modems? · · Score: 1
    66 MHz handling 10 MBps max data rate? Get the back of an envelope and a pencil.

    • That's 10M bits per second, about 10 bits per 8-bit byte (overhead, router delays) so 1M bytes per second.
    • 1MB/second on a 66 MHz processor would require no more than 66 clock cycles per byte.
    • Transfer of a network byte in Linux requires grabbing by the device driver, placing in buffer, giving completed packet to firewall/routing code, header examination of packet, passing packet to outgoing device driver, and pushing the byte to the card.
    • There are well under 66 byte-level transfers involved, most of the Linux kernel will be handling the entire packet.
    • The kernel might have to copy the packet between one and four times, but mostly a pointer to the packet buffer is passed around.
    • If your average buffer is 400 bytes, copying a pointer is about 1/400th the effort of copying the bytes (actually even less due to not needing a loop -- yes, clock cycles are needed for a loop even if you're using a multibyte copy instruction where the loop is done in hardware)
    • For a 400-byte packet, 66*400=26,400 clock cycles is available (subtracting the few cycles needed for touching the individual bytes).
    • From my experience with the Linux networking code, I think each packet requires much less than 26K clock cycles of processing.

    Now let's check my work.

    • When I traceroute a similar machine, I see delays of under 2 milliseconds.
    • 1,000 milliseconds per second divided by 2 ms of delay per packet equals 500 ICMP ("ping")packets per second.
    • 500 packets...if they had 400 bytes each...would be 200,000 bytes per second.
    • 200,000 bytes per second would be about 2,000,000 bits per second.
    • I am aware there are millisecond-level timing difficulties and network-related delays, but I've ignored them as here I'm trying to underestimate the maximum throughput rate.

    Okay, so in the first estimate I thought that 26K clock cycles would be enough but the second estimate came up with a low end of 2Mbps. I'm confident that a 66MHz machine is overkill for a simple routing table handling up to 1 1.5Mbps T1 circuit. There may be delays at full 10Mbps, but usually Internet bottlenecks will not allow reaching that speed anyway.

    Anyone else have more detailed values on their envelopes?

    Oh, you want a drag-and-spindle interface.

    Actually, you could just show it as a spindle with several labeled sheets stacked on it...moving the mouse over a sheet could display details, and the top and bottom sheets scroll up and down through the three hundred things you've tossed on there. Probably showing the spindle from above at a 45% angle would let the sheets be shown as stacked windows.

    Would it be impolite to have Eiffel Tower and Washington Monument images for spindles? Or if you use it a lot, a four-masted schooner spindle.

    Actually, sportsmen and food workers who handle dry ice routinely know that the simplest way to handle it with a little newspaper.

And squeezing the newspaper will show you that is not a good idea.

  17. Re: Halon on SubZero Chilled Alcohol PC Cooling · · Score: 1

    Actually, that was accurate. Halon-style gases chemically interfere with fire. Enough oxygen remains in the room to be fairly safe, with Halon it may raise your heart rate -- other gases have other side effects. In large computer rooms, whether carbon dioxide or suppresive systems are used, it is common to have gas masks (filters) or breathing apparatus (air tanks) in the area. Lights, sirens, and delays to allow evacuation are standard -- but also common are some masks in case getting untangled from machinery takes too long, or in case rescue is needed. Particularly if the cause of the fire involved someone getting electrocuted, and rescuers have to linger in the area.

  18. Re:Have you considered fixing the lights? on 'Roofing' Your Cubicle? · · Score: 1
    It often is easy to get half of the bulbs disconnected right over your own cubicle -- if you can't do it then it's usually trivial to request that the maintenance staff do it (they usually are who replace bulbs and often will put a note in the fixture reminding themselves not to reconnect them). This way there's still plenty of light for safety and non-reading tasks. Then a work light can warm up the area light.

    The other problem is that the screen often has reflections of lights which are one or two cubicles over; dimming those lights does not eliminate the reflection. Sometimes it can be blocked by putting a plant, set of books, or some other acceptable over-cubicle-height barrier. If that's not enough then it might be necessary to block it some other way. Some places hang opaque or translucent plastic panels from the ceiling grid where needed. Other buildings use fixtures which direct the light down instead of using the common plastic diffusers that splatter the light to the side.
