  1. Re:Does this include anti-aliasing? on XFree86 Release Plans · · Score: 2

    It would take more than an addition to 4.0 to support that, it would take a pretty fundamental change in X-Windows itself.

    X fonts are returned to the server from the font server as monochrome pixmaps. Font servers expect to send that, x servers expect to get that, and the client programs all expect that. You'd need to extend the X protocol to support grayscale pixmaps for the fonts, recode the font server to be able to send them, and the clients to be able to understand them.

    IMHO, I don't see it happening. Some client programs where it would be useful could be extended to do it the way Gimp does it (request the font at a size a few multiples bigger than needed, and resize it down on the fly), but it would be application specific, and I can't see very many applications needing it.

    I thought for a while about poking around in Mozilla and trying to add the ability to do that in there, but since I decided to do it, I haven't managed to get a single copy of Mozilla to run on either of my decent Linux development systems...

    I think Mozilla is a place it'd be nice to see that support.

  2. Re:A couple of points on Flying Car by end of year · · Score: 4

    I'm not exactly sure why your post ended up moderated so high, most of the points you made were addressed in the article.

    Nowhere did it say it flys 6 feet off the ground. The intitial test flight is 6 feet off the ground.

    If the device leaves the ground, its not a car. Hovercraft are not cars and can not be brought on or over public streets under their own power.

    Its definately an aircraft. In fact, the article specifically says its an aircraft, and when its available, anyone with a pilots license could fly it.

    On the fuel economy standpoint, aircraft are always rated in gallons per hour. A small aircraft like a single engine Cessna runs 8-10 gallons per hour. This thing has four engines, so 24 gallons an hour isn't bad and is what any pilot used to flying multiengine aircraft would be used to.

    So there's a perfectly good definition of what the vehicle is, and that's pretty damn good fuel milage for an aircraft of its type, probably too good.

    I first saw this aircraft probably six or seven years ago on TV. This company has been claiming this was right around the corner for a decade now. I don't believe they'll ever sell any, except perhaps a few one-off X-class planes (I doubt they'll get FAA certification on the design, its very expensive...) and I don't believe there is a big enough market to mass produce a new multiengine aircraft enough to get the price as low as they claim.

    This might be related to the Linux "use" at Lucas Digital that caused some discussion last week. Then again it might not and it just made me think of it.

    If I had a rack of Linux servers with ATX supplies (which, coincidentally, I do), and wanted to make sure they came back on when power was lost (doh, didn't think of that, what are you running a server without a UPS for anyway???), then I might use a spare 386 or 486 I've got kicking around to do it.

    Its a piece of cake to wire a relay to a parallel port, there's schematics all over the place on the net to do it. Trim the power supply's "on" pins, wire them to the relay, and you could easy control the power of 8 systems from the parallel port with maybe $40 worth of hardware. Its not exactly what the question was asking, but it might be useful. Maybe Slashdot needs something like this for when the machine misbehaves. ;)

    Also useful in case of an errant init 0 instead of init 6...

    Alternately, I think those Matrix Orbital displays with the keypad interface also have eight digital outputs on them, you could wire one of those to a serial port, and trigger the relays with those outputs. Running some monitoring software to put the status of the machines on the LCD, you've got a nifty monitoring/control system.

  6. Re:Star Wars Future on TPM movie reel stolen · · Score: 2

    The final print of the movie was spit out of a computer. Not "several scenes" were rendered by a computer on film. Every frame of the movie was.

    That's not that unusual, by the way. Avid systems and the like have been used pleanty of times for all-digital film editing. Once the images are in the computer, the output quality doesn't depend on whether or not any actual effects were layed into the film -- there was probably a bit of color correction done, and stuff like that.

    This is all the way movies are going to be made in the future. Its easier, and getting to be cheaper to do shooting, and editing in digital, and will soon be the preferred method of presentation too.

    It'll be a godsend for future film students too -- when the camera prices drop enough that digital film cameras are the standard fare at school instead of 16mm Bolex or other type cameras, it'll sure save a lot of $$$.

    I probably dropped $500 a semester or more on film when I was in school. And that doesn't by that much film. :)

    Launching a satellite is pretty far fetched -- he'd need to buy a piece of the radio spectrum he could use, and it'd have to be a fairly high power transmission, all things that are very unlikely to be allowed. Low power (DSS-like) transmissions are too prone to signal fade during rain and things like that -- and no theater owner in their right mind would risk being unable to show a film during a rainy day (when it seems to me to be the best time to see them!)

  7. Re:Star Wars Future on TPM movie reel stolen · · Score: 5

    There are in fact several theaters showing it. It had been talked about for the last year or so leading up to the release, and in my understanding (which is just from industry rags I've read), its only two or three theaters showing it, and its very limited showings (ie, not around the clock)

    The resolution used isn't terribly high, less than HDTV resolution, but higher than DVD. (1280x768 sticks out in my head, but that might not be right..., but its not even 1080i HDTV resolution)

    The explanation was that with the sharper focus, brighter image (no shutter used), and lack of garbage on the film, viewers wouldn't know the difference. I'm not sure they're projecting it onto a very big screen though -- that resolution seems low for 500 person megatheaters and the like.

    LucasFilm's intent over the last half-dozen years since I first read about some of the talk about the prequels, was Episode I would be shot on film, with test digital distributions. I *think* I remember reading that those test distributions are on custom hardware, basically on a high-rate DVD -- twenty to thirty minutes worth, much like a film reel -- although that may have changed, because I've seen gossip about the satellite stuff. I've lost the list I had of the theaters that were showing the digital Episode I, unfortunately.

    Episodes II and III are supposed to be shot digitally, without using film. Aparently Lucasfilm has been spending a lot of time developing digital film cameras that can push data off the camera and onto a high-speed storage system fast enough to do film quality recording without using film. 24fps is obviously the low end, I'm not sure how much bandwidth they ended up with for running at higher frame rates.

    Some of the reasons I'd read for the move was a significant drop in cost over time (a lot of arthouse films are being shot on mini-DV and other digital formats like Digital BetaMax, because $30 for a tape sure beats $100 for three minutes of film...) The most interesting feature I read about was the ability to prerender the effects and do the compositing in realtime at the camera -- so the monitors show the finished shot, and alignment issues and problems with actors not fully interacting with effects can be taken care of immediately. Also read rumors of experiments to do real time digital character rendering, so an actor in a motion-recording outfit can be in front of the camera, and the camera would end up recording the CGI character in real time.

    Anyway, I digress. Episodes II and III are supposed to go out for larger digital releases, with more of a push for them to be digital on III than II. That's why there's been talk about big theater chains arranging financing so they can do low-rate financing for their member theaters to be able to spend the hundreds of thousands of dollars it will take to put digital systems in megaplexes.

    It'll be interesting to see if theaters end up using a direct broadcast method of displaying movies as they shift to digital, or if they go with a multi-disc optical solution like a high bitrate DVD-based format. Personally I'd think DVD would be the way to go. They're cheap to produce, even as one-offs. There's no reason you could build military-grade decryption hardware into the playback units and key the distribution discs to that particular unit and theater. Steal the discs, its not of any use if you don't steal the reader. If the reader has to verify keys against the distributors system, then even stealing the unit won't help.

    Satellite seems unlikely because of all the differing times a show can play, and the expense of the satellite time.

    I had this problem at home, where my masquerading/firewall system also runs a 750 meg Squid proxy to keep my poor 56k modem from getting too bogged down when I'm using a bunch of computers at once.

    You just need to turn on or get someone to turn on port 81 as a valid proxy port. My assumption is you're running through a firewall, and there's a proxy that handles getting the data through it. That proxy probably has the common ones (80, 443, 8080) as acceptable ports. Using 81 is sort of wierd, but thats how to fix it.

    Right click on the image, and say View Image (figuring you're in Netscape) -- you'll be able to see what the error message is. If you get an error page, you're probably hitting a proxy that needs to be fixed. If you don't connect -- ie, eventually you get a can't connect error -- then its probably a firewall.

    I think it makes sense in some circumstances to do that -- especially in lengthy discussions, where people who typically consistantly make good comments might jump in late in the discussion, and end up far enough down the list where a moderator won't run across it.

    Someone who consistantly ends up with their posts moderated up to 2, 3 or higher probably should start at 2. I'd be more interested in reading those comments right away.

    Personally, I don't like this new categorization of moderator points though... what happens when one person promotes it for being insightful, and another for something else? Or do these just represent the old -1 to 5 scale? If so, I don't think its intuitive that "Informative" is more significant than "Insightful" -- since in most discussions, I'm more interested in insightful comments than simply informative ones.

    If they DO still represent numbers, then I think the numbers should show up with them. If they don't, I think some clarification of what happens when more than one moderator moderates a comment with differing reasons.
