    I was going to suggest the same thing -- two birds with one stone. I personally use Hugin for things like that. You take many high-res, overlapping photos. You can automatically match them up with autopano-sift and then use vertical and horizontal alignment points to stretch them out as you would prefer. If the results aren't close enough to use as an overlay as-is, if you had a hires modern map, you could load it and set the FOV to roughly match up with the FOV of your fully aligned pieced-together map, and then define control points between it and your map pieces. Optimization will then stretch the pieces to try to fit to your modern map while still being pieced together.

    And while, yes, qbasic is slow, it's certainly fast and capable enough to get a full-blown software rendering 3d engine operational in on a 286.

    Wireframe, sure. Or using QBasic to make PEEK and POKE calls (but if you're going to go that far, heck, you might as well right in assembly). But the per-pixel draw routes in QBasic on the 286 were abysmal, and even line draws were way too slow. I think it called a full screen refresh for each graphics call you made. I would know how slow it was; I wrote 3d engines on the 286, both true 3d and raycasting. The 286 could barely handle *compiled* 3d; A10 Tank Killer was about the best it got. True compiled 3d didn't get half decent until X-wing on the 386.

    The slow performance of QBasic was the reason I begged my father to buy me Borland C for my birthday back in 7th grade. I was completely blown away by the performance increase. But I'm still glad I learned in basic, as going from "no programming" straight to C would be a pretty big jump. I remember that in my first C program I was hit by a persistent bug that required a #pragma statement to get rid of. I can't imagine if I hadn't known how to program at all before that point.

    For my tastes, I prefer an MMO that goes out of its way to create as real a virtual world as possible.

    So by that, do you mean "as aesthetically realistic as possible" (graphics quality, sound, perhaps physics), or something more than that?

    BTW -- in terms of aesthetics, here's what to expect in games in a couple years.

    EQ, EQ2 and WoW are good examples of fairly well fleshed out MMO worlds with good physics

    What do you mean by "physics"? I've never thought of them as containing what would generally pass for a realistic physics model (say, PhysX, Bullet, Havok, etc) -- just pre-calculated special effects and the ultra-simple equations (like gravity). And there's big challenges involved in using real physics, in that physics is CPU/GPU intensive and for everyone to have the same experience and to avoid cheating, it needs to be run on the server (increasing hosting costs). Well... I have come up with one alternative, but it's not pretty (dispatching the calculations for each region or task to half a dozen random clients and then going with a majority-rules basis for whose results are correct). If you just rely on one client to do each of the calcs, they could use a hacked client that could rig them and cause all sorts of cheating. And if it's not random, you could end up with groups of hacked clients working together to vote the same rigged results.

    This could work even in a serverless MMO, but it would require something like a Kademlia network.

  6. Re:Corporate Shills on US Gamers Spend $3.8 Billion On MMOs Yearly · · Score: 4, Interesting

    Some of my fondest coding memories were programming for an LP mud. :) I loved the fact that wizards (coders) could literally have programming wars. For example, one wizard makes a dest ("destruct" -- basically, kicking off another player or wizard, with a lot of fanfare) that has a big leadup to it. So another wizard, tired of getting dested, writes a rapid counter-dest that kicks off the wizard doing the dest before it completes. So the first wizard writes an insta-dest that doesn't give the second wizard a chance to counter. So the second wizard writes an object that seeks out the first wizard's inventory, intercepts their commands, and if they try to start a dest against them, it instead turns the dest on its caster. So the first wizard writes an object that scans their inventory for objects to intercept the dest, and if it finds something that shouldn't be there, the object kills it off for them and then dests its owner. And on and on, back and forth.

    Then there was the simply humorous aspects. A friend of mine had a dest where he would pick up a flower and contemplate whether the person being dested loved them. "(S)He loves me; (S)He loves me not. (S)He loves me."... and so forth, ending up on "(S)He loves me not." As they throw the flower away, the person gets kicked off the server. So I wrote a parody wherein, first thing, an object gets added to the inventory of the target to prevent them from quitting or counter-desting. A bumbling ogre version of my friend stumbles in and picks up the person being dested and starts pulling off limbs, doing the "(S)He loves me, (s)he loves me not" thing with them, and causing the person to randomly scream out in pain.

    I used to occasionally disguise myself as the developer's board in the main development room. When people tried to interact with me, I'd manually make up responses. Occasionally I'd jump into other wizard's inventory or other things like that, perhaps making myself into a talking sword and having them wield me or the like. A neat feature was that you could "patch" objects to call any function that object possessed, including the objects that it inherited from. So changing things' descriptions or making them call actions was a snap.

    I once wrote a program that would compile statistics about the most used words on the wizard chat line. When I informed everyone of it, all of the sudden, they started shouting out random obscene words over and over for days on end to try to get them high up on the ranking list. ;)

    At one time, I accidentally wrote an object that landed on the floor of the room everyone logged in to and which dested anyone the instant they logged in. This kicked off all but one player, who was in another room coding an area. I couldn't get in to tell them not to log out and to please dest all objects in the login room; if they logged out, we'd have to wait for a sysadmin to restart the server! So I connected in through the FTP server and uploaded some files in the area they were working with file names in all caps that would tell them what to do as soon as they LS'ed. Thankfully they did ls, noticed the files, and fixed the problem!

    Which raises some good questions, re: lowest common denominator. The general question with MMO design isn't whether the focus should be grinding to gain more ability, or even whether the focus should be grinding in combat to gain levels; it's "what sort of variant of a common formula should be used". A MMO that doesn't stick to the standard tank/healer/damage dealer party formula gets considered as innovative. And, sure, there's usually some form of resource harvesting or crafting in addition to the fighting, but that's usually half-arsed, and even more of a grind.

    Sure, there are exceptions. But not many. Second Life an obvious one, for example, but that's little more than a graphical chat room, and a couple steps away from being an interactive porn site.

    Is it unreasonable to expect more diversity from MMOs? Or is the grind, and in particular combat grind, the only formula that will really work?

    I'm curious as to what others think about the subject.

    As for the ice issue: 600m metric tons at the "north pole". They say it's within green circles that look to take up something like 4% of the image. The area covered is down to 80N. The moon's circumference is 6790 miles. I'm too lazy to do the exact math, but that means that the area covered here is something like 550,000 square miles. That means that the area taken up by the green circles is something like 22,000 square miles, so about 27,000 metric tons per square mile. Mini-SAR measures to a depth of "a few meters"; let's say 10 feet. That would work out to about 100 grams of water per cubic foot in those areas. A cubic foot of regolith has a mass of something like 75 kilograms, so that would be about 0.13% water.
