    While we might run out of cheap oil in the near future, I don't see a non-nuclear future, nor even a limited-consumption one.

    Putting that aside for the moment, concrete roads can be made by hand. Build a road or harvest a crop? Easy: if it's harvest time, get the crop in. Otherwise, build a road. Build a road or heat hundreds of homes? If it's come to that, people will relocate somewhere with a milder winter -- or more likely, they'll have dug in deep, and live in multi-family earth-insulated things.

    My point being that if an energy shortage gets so bad that we can't use heavy equipment, it still won't look like you imagine. People will move where a life without heavy equipment is more feasible, and if they have to do it on foot with carts, they will. People will build and maintain roads without heavy equipment, with wheelbarrows and shovels. They won't sit down and wait to die in deprivation. The people of the world have lived a low-oil low-energy life in centuries past, and if you imagine a future like that, you should look to history to see what that life will be like.

    Your expectation of roadbuilding as a capital offense seems not only draconian but unreasonable. Roads make for efficient transport, and efficient transport reduces the energy cost of everything. Your imagined future has people sitting in roadless isolation, spending all their resources on winter heat, rather than building a road to trade for blankets.

    There are many, many paving surfaces other than asphalt. Concrete, for example. Even the most disastrous of peak oil scenarios won't result in bad road - just more expensive, more durable road that has to cure before use.

    I'll buy that future cars will be lighter-weight, and that wheels will be narrower than they are now. Current cars are heavy because of safety mandates, and I think future cars will get their safety from lighter materials and active computerized evasion of danger. Wheel width gives better grip, meaning more acceleration and cornering, but better materials will give us the same grip in a narrower package with less rolling resistance. Overall I think we'll see not much performance change from right now - when the computer is driving, the performance-feel of your car is less visceral and therefore less a part of the car selection process.

    I'd say they'd be cheaper in terms of work-hours needed to buy one, but even if they aren't, computer driving makes it possible to run automated taxicabs very cheaply. The line between car rental and cab service blurs, especially for longer trips.

    Germans may suck as human beings but they know how to make cars. Cars that actually just bloody work instead of needing to be fixed every ten miles.

    Speaking as a man who used to own a 1995 VW Golf, I have to take issue with you on this.

    Germans made a car that in theory was reliable and well-built and efficient. In fact it was continually breaking down, costly to fix, had exterior parts falling off every summer when the adhesive softened, and rarely got more than 25 miles to the gallon out of a gutless 2 liter engine. Also, the seats were uncomfortable, and my ignition switch assembly caught fire while I was driving one day.

    The 2006 VWs may be better, but my sister-in-law bought a 2004 Jetta, new, and it was totalled when the electric seat heater caught fire.

While it's great to know that this bus trip is $1.35, compared to $3.97 assuming the IRS-approved $0.405 per mile, it should also say 33 minutes compared to 9 minutes, so by taking the bus I'm spending 24 minutes of time.

    Googling for the string "($3.97 - $1.35) / 24 minutes in dollars per hour" gives $6.55 dollars per hour. This would also be nice to have there; it might make more sense to work another hour each day, assuming you'd get paid for it, and your car is already a sunk cost.

  13. The deal with mp3 on MP3 Going the Way of the 8-Track? · · Score: 1

    I have quite a bit of music stored digitally. Some is mp3, but anything I rip off of cd gets archived as an APE (Monkey's Audio) lossless file, one file per disc, with an embedded cuesheet. On my PC, I can't hear the difference, but if I make a cd from mp3s for listening in my car, or on my good stereo, I can hear compression artifacts in certain passages. This wouldn't be enough by itself to make me waste the disk space for lossless, but I also like the convenience of having a single file represent a single CD in my collection. At some point I will probably batch-convert all my APEs to AAC - most likely when I get an iPod. This also factors into my decision to use a lossless format for now; transcoding from one lossy format to another is never good, and often really bad for quality.

    Of course all the stuff I download is mp3, and there's no point in converting it.

    I would probably download more mp3s if they were better ripped and converted. Here are a few tips for anyone who is ripping for sharing purposes:

    1. Rip with Exact Audio Copy, or a similar secure ripper
    2. Encode with a recent build of LAME, using --alt-preset-standard

    Salyut 3 was launched on June 25, 1974. It was another Almaz military space station, this one launched successfully. It tested a wide variety of reconnaissance sensors, returning a canister of film for analysis. On January 24, 1975 trials of the on-board 23mm Nudelmann aircraft cannon (other sources say it was a Nudelmann NR-30 30mm gun) were conducted with positive results at ranges from 3000 m to 500 m. Cosmonauts have confirmed that a target satellite was destroyed in the test. The next day, the station was ordered to deorbit. Only one of the three intended crews successfully boarded and manned the sation, brought by Soyuz 14; Soyuz 15 attempted to bring a second crew but failed to dock. Nevertheless, Salyut 3 was an overall success.

    In many orbits, you have a fair amount of leeway to change to other stable orbits, so the fact that your orbit will change is no big deal. Here are some other mitigating factors:

    • You can mount a projectile weapon axially, and aim by pointing the whole vehicle where you want to shoot. This means that while you do change your velocity (and therefore orbit) when firing, you do so in a stable, predictable, and slow manner that doesn't affect the orientation of your ship.
    • Have you calculated how much recoil force is involved yet, for a 23mm shell, an autocannon action, and a Salyut-type space station? I bet it's less than you initially estimated.
    • What recoil force there is can be totally compensated by firing another shot in the opposite direction, possibly even at the same time.

    Also note that delta-V is "change in velocity", so firing doesn't alter your delta-V, it gives you delta-V, or as most people would say it, changes your V.

    Equal weaponry, yes. But the axis team has a serious advantage on all but one map. If you want to be a nice guy and use auto-team, more often than not, you'll end up on the camped-against allies.

    Axis static defense strategies can nearly always be defeated by the proper Allied class mix and proper teamwork.

    Medics (after they get enough XP) are too powerful. Likewise for panzerfaust wielders. Weapons like the machinegun, mortar, and flamethrower are only useful in a few situations.

    High-rank medics are quite powerful, and a popular class choice, but medics alone cannot win a map. Their self-healing and adrenaline abilities make them no more powerful in a short sharp firefight than a top-rank engineer, who has bonus grenades and a flak jacket.

    Panzerfaust soldiers are limited in several ways: the heavy weapons server cap, the low number of pf tubes issued per ammo box, slowness in moving with a heavy weapon equipped, and the class-specific-skill recharge rate. The latter two disadvantages are somewhat reduced as XP is gained, but only heavy weapons XP counts toward those. There's also the 2-second firing delay with the panzerfaust, during which the firer is quite vulnerable.

    The machinegun is the cornerstone of playing defense, if you have some backup. The panzerfaust (or an engineer with rifle grenades) is how you defeat a well-placed machinegunner. The mortar is great if you have good field ops spotting, or if you have worked out bearings and elevations for your favorite firing points and targets in advance.

    But more importantly is the bullshit XP system they've implemented. If you're playing a three-map campaign and you join towards the end, you're faced with opponents who have skills much higher than you. Don't even bother playing a six-map campaign unless you start from the beginning.

  24. SCA, Rattan, and Live Steel on Virtual Sword Fighting · · Score: 2

    There are several ways to make swordfighting safe for practice purposes. You can use real swords, blunted, and avoid swinging for the head (Empire of Chivalry and Steel does this). You can use foam swords of various degrees of hardness, and then armor is almost unnecessary. You can use a wooden sword with padding on it (like the Historical Armored Combat Association), and light armor. Or, as in the SCA, you use hard wooden swords, and heavy metal and / or plastic armor.

    None of these systems can accurately reproduce all the nuances of real to-the-death sword combat.

    For safety reasons, live steel is out. Foam swords are far too light; you wind up moving them in ways that real swords simply don't. SCA swords bounce off armor exactly wrong, and they tend to be round, making it hard to tell when you are throwing flat (the aerodynamics of a real broadsword make this obvious), and SCA rules prohibit shots below the knee. The padded wood swords that HACA uses feel right and swing right, and with heavy armor you can even play full-speed, full-force (HACA members often say they can go full-speed and pull your shots, which just demonstrates that they are used to going slow, I think).

    The HACA system would be the best combination of safety and accuracy, but it is not popular enough to have the critical mass of players needed for advancement of the style. Last I checked, it was still low-speed cut-and-thrust stuff straight from the books, and a giant chip on their collective shoulder about it.

    The inherent problem with the HACA system is that, like all these, the sword doesn't cut, and that matters. Take the Viking Holmgang style - three light center-boss round shields per combatant, and the sagas tell us it was quite common for blows to cut through the shield, and the leg beyond it. Therefore, correct use of a light Holmgang round shield would be to block with the boss, and probably try to bind your opponent's blade in the wood of your shield. This can only be done with a sharp sword. QED, no system of swordplay can be both safe and accurate.

  25. I was a Teenage Fax-Spammer! on Firm Pays 6.5 Million for Fax Spamming · · Score: 5, Informative

    Well, kind of.

    We had a company that did outsourced corporate training. We faxed a list of our upcoming classes to our former customers once a week. Our customer list grew, and I think that our marketing people started buying lists of fax numbers and adding them to the database.

    This was accomplished with two two-line Hayes JT Fax boards, IIRC, installed in an old 386 (for reference, this was the early Pentium era). I built the box, I ran the cable (a single strand of 8-wire cat 3) and kluged up four-headed RJ11 ends for it. We bought some software that could watch a directory for instruction files and pump out faxes accordingly. We would make a series of sequentially numbered .GIF files, one per page of the fax (normally two pages), and then run a little utility that took a file of numbers to send to, a file of numbers to NEVER EVER send to, and the name of the first .GIF file. It made all the control files, and I would leave for the weekend. 4000 numbers, 8000 pages, 4 lines, no problem.

    Further technical note: about once a month I would go into serious log analysis mode, and remove the 50 slowest fax machines from my list. Most fax machines at the time were 9600 baud, with some 14.4kbaud, and a dwindling minority of 4800, 2400, and some 300 baud horrors. We only sent on the weekend, so it was in our interest to only target fast recipients.

    Every Monday, we'd have a pile of response faxes, normally just "take me off your fax list", often with no phone number to reference, but sometimes we would get counter-spam numbering in the dozens of pages. We were happy to add anyone who wanted to the NEVER EVER send list.

    The punchline: In almost a year of doing this, we had two or three people take classes because of our faxes - not nearly enough to cover the cost of the fax server, let alone my time maintaining the whole system (never less than 2 hours a week, often more like 4).

    Spam is bad. It doesn't work. I can't figure out why people keep doing it. Is the word not getting out there? IT DOESN'T WORK.
