  1. Re:You obviously haven't seen an HDTV broadcast... on Using Bandwidth Of HDTV · · Score: 2
    Until *all* shows are shot for HDTV, there's little point in spending for it. It's a boondoggle Congress forced on us.

    There is a huge amount of content, such as movies and old television shows, on 35mm film that could be broadcast in high resolution.

    Third, there is NOTHING to stop you using tunnels to convince your ISP that you never visit any place of interest.

    I wouldn't bet on it. The terms of service of some cable modem ISPs prohibit VPNs.

    Codecs convert one form of digital data data to another form.

    No, that is incorrect. A CODEC (coder/decoder) is typically used to transform analog signals to/from the digital domain. The integrated circuit that the telephone company uses to convert analog voice on subscriber loops to/from 64 KBPS digital data streams is a CODEC.

    I've found that a simple "No, thank you." works very well. Don't try to argue or negotiate with them.

  5. Moderate the Telephone System on On DDoS, SPAM, Telemarketing And Harrasment? · · Score: 2

    It seems to work reasonably well on slashdot, why not moderate the telephone system? The telephone company could keep track of each subscriber's karma, and refuse to connect any calls when the caller's karma was less than a threshold set by the called party. After each telephone call, the called party could punch in a moderation code on their telephone to increment/decrement the caller's karma.

  6. Re:Instant on == instant problems on Instant Access Memory · · Score: 2
    If you pull the plug, the state of memory is retained, but the CPU state is lost.

    Some older systems (PDP-11) support a power-fail interrupt that allows the CPU to save any volatile state information in core (non-volatile) memory. I don't know if any PC hardware supports this.

    The password file was encrypted with a mutant version of DES. The crypt(1) program used a one-rotor version of Enigma.

  9. Cryptolgia on Information On Cryptography And Effects On Society? · · Score: 2
    Cryptologia is a journal that is a wonderful source on the history of codes and ciphers. There have been four books edited by Cipher A. Deavours (and others) and published by Artech House of selected papers from Cryptologia:

    Machine Cryptography and Modern Cryptanalysis, 1985, Out of Print

    Cryptology: Yesterday, Today, and Tomorrow, 1987, Out of Print

    Cryptology: Machines, History and Methods, 1989, Out of Print

    Selections from Cryptologia: History, People and Technology, 1998

    You might be able to find them in a good university library.

    Aegean Park Press is another good source of historical material on cryptography.

  10. Re:A console first! on Microsoft Unveils Gaming Console · · Score: 2

    It's a console, not a PC. If Microsoft has any sense, they will weld the case shut. Developers want a standardized platform, not one with an infinite variety of CPUs, RAM configurations and hard disks. If it breaks, exchange it under warranty or toss it in the trash.

  11. Re:Futile straw men burning on Ecological Engineering · · Score: 2
    Although, pollution from burning contaminated wood would probably not be significantly more harmful than that from burning uncantaminated wood and certainly would be less harmful than the emissions from your friendly neighborhood coal-fired power plant.

    I wouldn't bet on it. A wood fire in a conventional fireplace or wood stove is very dirty. This page has some information from the Department of Energy on pollution from burning wood. I have read EPA literature that states that wood burning stoves are by far the worst polluting residential source of energy.

  13. Evolution not Revolution on The End of Unix? · · Score: 2

    There are many things that could be done to improve the speed, scalability, security and reliability of UNIX systems (including Linux and *BSD). Some of these might require substantial kernel rewrites but they don't require a brand new operating system. Sun pulled this off when they switched from SunOS to Solaris.

    Hopefully, the patent office will treat this like they treat applications for patents on perpetual motion machines.

  15. Re:GPL and API's on OpenAL Audio Library Released · · Score: 2

    You might be able to copyright the names of the functions in the API. Computer manufacturers have claimed copyright on the assembly languages that they create for their systems. Assuming the copyright is valid, that doesn't stop someone from writing their own assembler, it means that you have to change the assembler's instruction mnemonics to something other than the manufacturer's mnemonics. You could do the same thing with an API, although on some operating systems there is the problem of dynamic linkers looking for ASCII strings containing function names to bind API calls.

  16. Re:What's most important on Database Nation · · Score: 2
    Non-citizens (businesses, institutions) may not provide to a third party information specific to a private citizen without the express written consent of the private citizen.

    The problem with written consent is that it may not be voluntary in any practical sense. This is a big problem with medical insurance and medical treatment in general. For most people, declining employer subsidized health insurance is not an option. It isn't realistic to expect people with serious illnesses to shop around or argue about the hospital's privacy policies. When you are really sick, you will sign any paper they give you if it results in access to a doctor and medical care.

  17. Re:Gee, Gnome on Genome Project Squabbling · · Score: 2
    I was of the understanding that the human genome project was funded and overseen by the United States Department of Energy? Doesn't this more or less nullify patenting of that information?

    U.S. Government employees can obtain patents. You may be thinking of copyrights. In general, material produced by the government can't be copyrighted. Besides, can you talk the original author into registering the copyright?

    I agree.

    I don't know anyone who has ADSL or a cable modem. They all use 28.8 or 56K modems with 14-17" monitors.

    The old rule of thumb used to be a one second response time to user input. That is 3600 bytes at 28.8 kbps.

    I feel like slapping the web designer every time I see another insanely bloated web page that takes a minute to load.

  20. Re:SGI Continues to plummet after adopting Linux.. on Tera Will Buy Cray Research · · Score: 1

    It's an old idea. IBM and others used to make special high speed disk drives for VM paging. When RAM got cheap enough, the mechanical drive assembly was replaced with RAM with battery backup. The interface was the same but the performance was much better. Adding the same amount of RAM to main memory may not be possible due to architectural limits or lack of expansion space in the CPU cabinet. Some systems support "bulk memory", which isn't directly addressable, but can be used for paging or caching files.

    They have a computer that dials many phone numbers. When it detects a human has answered the phone, as opposed to an answering machine, it connects the call to the next available telemarketing drone. The goal of the system is to keep the drones busy talking to potential customers, not listening to ringing phone lines or answering machines. They annoy the hell out of me, it's as if someone has put you on hold before the conversation has even begun.

  24. Re:Define mainframe on Experiences of Running Linux on a Mainframe · · Score: 2
    If Seymour Cray designed it, it's a supercomputer.

    There is some overlap, classic supercomputers, like mainframes, have very high performance I/O and memory systems. Both tend to have huge amounts of RAM and disk space. The word size on a supercomputer is usually equivalent to the size of a double precision floating point variable. The IBM 360/370/390 is a 32-bit architecture although its main memory address space is much larger than 32-bits. The mainframe has a hierarchial memory system (L1 cache, L2 cache, main memory, bulk memory) where the classic supercomputer does not have a cache. The supercomputer streams operand vectors from memory to vector processing units in the CPU and the results are streamed back to memory.
