    Four hours.

    5 AM to 7 AM is a two-hour period. 5 PM to 7 PM is a two-hour period. That's only four hours.

    I know I'm getting enough when I wake up before the dog (my Greyhound whines when she is needing to be let outside in the morning)! Nowadays we hit the hay between 10 and 11 PM. I used to function just as well staying up to about 12.

    Even when I was in school (Georgia Tech) I didn't stay up much past 12 AM. I didn't live on campus and had 8 or 9 AM classes. Furthermore, I never pulled an allnighter; rest and freshness was more benificial than an extra hour or two of frantic (and useless) study.

  2. Re:Reasons for broadband slowdown on What's Holding Up Broadband in the U.S.? · · Score: 2, Insightful

    Well, perhaps that's an exaggeration, but a glance over the history of Cable/xDSL stories on /. will reveal the outrage whenever a company attempts to make their offering profitable with caps and volume charging.


    No, the outrage comes from the service providers failing to live up to their (possibly implied, via advertising) contractual obligations. If I sign a contract with an ISP stating I'll give them $50/month for the next twelve (or more) months, and in return they'll give me "always on, 1.5 Mbit speed, blah blah blah" they'd better live up to it. They're the ones that wrote up the service agreement, right?

    I write this as one unable to get DSL, but I can throw a rock from my house to the wirecenter. I was -->right out. I could get Earthlink cable I suppose, but I'm not sure about the service people at TWC; they'd be the ones doing the hardware.

    Memory is not storage.

    Storage is where the computer puts things that it isn't dealing with at the moment; disk space is the normal storage medium.

    Memory is where the computer holds things that it is currently dealing with.

    I like the hands analogy. The computer's memory is like your hands: if you're working with something, it's got to be in your hands. When you're done fiddling with it, you put it down (send it to storage).

    This guy is just wanting to make a powerful diskless compute server, which is great except for one thing: most modern operating systems use, if not require, virtual memory (a region of storage that is used as a temporary holding area for thing that are not currently being worked on, but will be needed shortly). To the user, VM looks like memory, but it's really just storage in a funny suit. Having VM over a network would be painfully slow, I imagine. (Imagine how slow a Beowulf cluster of these diskless compute engines would be!)

    At the bottom of page 85 is a 1/3 page ad for Abacom Technologies. They sell ISM (418 and 433 MHz) band Rx and Tx modules that could be pressed into service for what you want. One drawback-- half duplex only. But it's a complete 38,400 bps transiever for $140.

    On page 47 Radiotronix has an ad, but their stuff is limited to 4800 bps.

    On page 32 there's a feature article about a wireless (RF) irrigation control system. It's not exactly what you want, but it will tell you some of the things to think about.

    Their CMX017 transmitter and CMX018 receiver can be used to build such a device. For your speeds they'll do fine (I wanted 10 Mbps; they won't go that fast!).

    Nope; their stuff looks like remote controls (keyles entry stuff) only.

    (Gets out Maxim selector guide)

    Hmm. These guys have a range of 1800 MHz PCS and 800-1000 MHz tunable tranceivers. These could work.

    No, none of these are "turnkey" solutions and they all have their drawbacks. It's not true that stuff isn't out there. The Abacom Tech stuff is very, very close.
    You just have to realize that this is a very small market; just because we have PDAs (I just got a Visor Prism for Christmas!) doesn't mean there's enough PDA owners to support such a device.

    I might like one, but right now my latest hardware project will be making a battery charger for the Prism that doesn't cost the $50 they want for a cradle. My computer isn't on the way out of the door in the morning; it'd be nice to have a non-HotSync-able cradle by the door just for charging.

  6. Re:You must understand the technology to use it on Let's Kill the Hard Disk Icon · · Score: 1

    There's nothing wrong with understanding the internal workings of a machine. I would argue that intimate knowledge of its operation is an imperative to extracting the maximum benefit from its use.

    To answer your question: disk space is not memory. It's storage. Even if it's used as "virtual memory," disk space is storage.

    It's like this: you only have so many hands (computer memory). Each hand (allocation block of computer memory) can only hold so much. If your hands (computer memory) are full but you want to pick something new up (allocate more memory), something has to get put down (go to storage, or perhaps thrown away). "Virtual memory" is a special case of storage such that the items that are put down are kept close by so they can be picked up again, like putting the scissors on the counter instead of back in the drawer, but it's still storage.

    Extracting the most utility from a machine comes from fully understanding its abilities and limitations, which follows from knowing how it works. For example, cadidates hoping for an aircraft type rating (required to operate aircraft with gross weights greater than 12,500 pounds) must understand each of the particular airplane type's systems and be able to explain to an examiner how they work. While that kind of detailed computer knowledge may not be required to check your email, it would certianly come in handy when your email suddenly doesn't work. Or you don't know how to stop the flood of ILOVEYOU messages from appearing in your inbox.

    People: just write the number out: seventy-eight thousand.

    Ximian has an answer for that: Red Carpet (usually) works great. Lately they've had some signature deficiencies, and there have been some dependencies that got missed WRT GIMP modules last night.

    Hrm. In my post I prodcue a working definition for "censorship," while you merely say that it "has to do with the act of censoring." First, what you said is vacuous because it's circular: something is X because it deals with X.

    What you completely miss is the fact that nobody besides the government is capable of censoring in the way that most people think about censoring: completely removing an idea from public consumption.

    Yes, there are things called network censors that "clean up" objectionable material from television, but these people are only able to do so for whatever network they work for. For example, last week FoxNews decided not to air videotape they had of the WTC buildings actually falling on people. This benevolent self-censorship is in my opinion A Good Thing; there was no need or reason to show individuals dying. Shepard Smith even said on-air that the tapes weren't fit for public consumption. The world is grotesque enough without adding to the horror.

    When most people think of censorship, they envision Sovietesque repression. This malevolent brand of censorship is only possible when carried out by a government agency under threat of bodily harm. Individual outlets may choose not to carry an item, but there's always someone that will unless they're crushed by a larger power.

    The Honorable Senator Bob Graham
    2252 Killearn Center Blvd, 3rd Floor
    Tallahassee, FL 32308

    RE: DECREASING LIBERTIES IS UNAMERICAN

    Senator Graham:

    This week we've witnessed many horrifying and unprecedented events. Many people have asked or will ask you to do "something" about the hijackings that took place Tuesday morning. I would like to advise you to be calm, thoughtful, and most importantly courageous. This is a time for all of us to emphasize what has made
    the United States great: the freedom of its citizens. It is my opinion that what happened Tuesday was aided and abetted not by lax government control and security, but rather by a lack of liberty on the part of the American public. Furthermore, I've seen absolutely no indications that the Federal Government are going to fix the problem, or even comprehend it. In this respect the terrorists have succeeded: the American public enjoys fewer liberties today than on last Monday with little benefit.

    Already I have heard reports of bills to be introduced to Congress and new policies instituted by executive agencies that, while ostensibly are designed to protect Americans, will actually end up hurting them. In the rush to do something, too many times the wrong thing is accomplished. This is one area where the Law of Unintended Consequences will no doubt be a major player in public safety for years to come:

    * One report I've read was on Wired news (http://www.wired.com/news/politics/0,1283,46816,0 0.html) says that one of your colleagues, Senator Gregg of New Hampshire, plans to introduce legislation that would require all encryption systems to have a Federally-approved "back door" to make it easy for law enforcement agencies to "crack" suspected communications. If this bill becomes law, the only people it would affect are law-abiding American citizens. Terrorist or other "bad guy" organizations would of course circumvent this law by either not upgrading to "approved" versions, or by developing their own encryption codes. I would implore you: do not support any legislation that has as its goal the reduction of the rights of Americans in the false hopes that it would increase their security.

    * Before this week, the Federal Aviation Administration allowed passengers of airliners to carry knives with blades up to four inches long. The weapons used in the attack were therefore legal. The new rules (http://www.faa.gov/apa/faq/pr_faq.htm) forbid the carriage of any knives, even little plastic ones like that found at fast food restaurants. This is exactly the wrong course of action. What we need is a public that has the freedom, the liberty, to defend itself with force if necessary. Citizens of the United States that have concealed carry permits, are members of any law enforcement organization or serve in the United States military should be allowed to carry weapons on airliners. I can think of few better examples than last Tuesday of what the Framers intended for these words: "A well regulated militia, being necessary to the security of a free state, the right of the people to keep and bear arms, shall not be infringed."

    Thank you for your time and consideration; this is a grave time for us all, but please remember what has made this country what it is: the freedom of the people. Give these people the freedom and power to protect and defend themselves. Restricting freedoms means only that we are more vulnerable than we were before.
