What? That statement is like prophesying the weather thusly "20 years from this moment, we will have a nice and sunny day... Or not."
Did everyone 20 years ago expect that we would reach the plateau of hardware and software development very soon, or alternatively, decide that technology is a fad, and then go back to slide rules and abacuses? I doubt so.
Maybe it has something to do do with climate. I had a HP-500 series which was continually drying out. I don't think I ever actually emptied a cartridge without it drying first. (and no, alcohol and swabs don't do a damn bit of good!) Thing is, I live in Colorado, so the humidity is low and the altitude is high, both of which could promote cartridge drying.
I also live in Colorado, and my desktop printer's cartridges wouldn't dry up so much as just clog very rapidly. Ever since I put in a humidifier so that my nose wouldn't bleed all the time (just too damned dry), my printer doesn't clog during relatively long periods of non-use. It's Magic, I tells ya!
I dunno, I used to work with a 3M Scotchprint 2000 electrostatic machine, it would do 2000 feet of 54" material at 400 DPI an hour, which if IIRC, was about 33 feet per minute. The ripped images were separated into their individual colors, and each color was stored on a separate 10,000 RPM SCSI drive, and each were streamed into the printer. It kept up with the printer, but I tell you, there wasn't that much overhead... But that was a while ago, and the electronics have come a long way.
If they have this linear array of nozzles shooting out 1 foot per second, there is one reason I don't see this working, and it's not the need for a highly specialized workflow:
It's all about absorption and drying of inks. Most medias will absorb inks fairly slowly. I also worked with a 52" HP 5000 inkjet printer. It was entirely possible to print so fast (with our slow-ass printer) to not allow our inks to, first of all, get into the coating on our media, and secondly, to dry enough so that the next passes didn't oversaturate the coating. We had to set our rip to build in a delay between head passes when we were doing jobs with full saturation, otherwise things looked like crap because the inks blended together.
For this reason alone, I think this technology is most likely horse-hockey. Unless huge advances are made in coatings, the technology, even if it were capable of these speeds, will be useless.
Oh how your comment reminds me of a policy of a place where I used to work. It stated (more or less) 'in order to protect the security of the network, downloading copyright protected information is prohibited'. Keep in mind that this was approved by lawyers.. they seems to have ignored the basics of copyright law in school, anything published is copyright protected
Well, sure... But maybe they expected you to browse sites with only expired copyrights, or sites that were entirely public domain... I mean, that's doable, right?:)
Heh, I might have noticed that, but I felt an aneurysm coming on due to the bad layout, and my laptop just about shat itself rendering the 2000 pixel wide page on its little 1024x768 display.
OTOH, I'm sure we can make some kind of parody site based on this, like profane-injustice.org, where we make fun of stupind people on the internets.
What a stupid bitch. I'm ashamed to live in the same state as her.
The way I see it, there are certain ways to make sure spiders don't index your pages, and we should agree that if one is smart enough to put a web site on the net, one should also be smart enough to learn how these work. Good spiders like any of the major search engines and archive.org will restrain themselves if you setup a robots.txt file (or meta tags) that tell them they aren't welcome.
If she really didn't want her data to be copied, she should have stuck it in a password protected directory, and she could have made her nifty copyright exclusion/contract agreement to apply after users entered the supplied passwords.
This one is simple: Viacom. They don't need to sue for 1 bilion, but YouTube needs more reviewers (or improve their copyright protection). Viacom certainly spent a few bucks on producing these TV shows. They can't simply give it away for free. It is *their* products, and *they* decide where it can or can't be redistributed.
Actually, according to subsection (c) of section 512 of the DMCA, providers or any size aren't required to have ANYONE reviewing their sites' content. The only thing required by YouTube is that they promptly disable pages when they get a valid complaint letter.
So the case is obviously that Viacom needs more people searching for their own content.
But the story is different because the system will know what to do when it runs out of ethanol, which is to say retard timing and reduce mileage and power output until you add more ethanol. Water injection is aftermarket and usually not compensated for automatically.
The mileage improvement is pretty compelling and I think we'll see it implemented if fuel prices rise much more.
Like the anonymous user noted, modern cars have anti-knock sensors, and they will retard ignition, or reduce boost, or both.
But here's the real deal: The primary purpose of water injection is to cool the air as it enters the intake manifold via evaporation. Water injection works just like a swamp cooler.
More than that, however, most cars with electronic fuel injection have a Mass Air Flow sensor, and an intake temperature sensor or some combination of other sensors, and the computer uses these sensors to figure out how much fuel it needs to squirt out at any given time. In other words, the facilities to do this are ALREADY fully automatic and in operation in production cars, which are not even designed with water injection or turbo charging in mind! It's not rocket science, it's been there forever.
Real world mileage rates, however, won't show that much of a difference. Water injection and turbocharging are all about packing more air into a cylinder. More air means more power, and more power means more fuel, and that means worse mileage. The only way to get the numbers they quoted will be to design engines that operate closer to their peak outputs, at wide open throttle, most of the time. We're talking about a small engine (less than two liters, and closer to one liter, for a start) designed to consistently operate at high boost.
Hate to bring it up, but if this ever did catch on, just think about all the noise traffic this will cause underwater. Its already been shown the current levels of human caused noise are the cause for various animal beaching, id hate to think what this new system might do
Oh, I'm so sure a horde of these will compete with the 20+ foot diameter, 50+ TON propellers that routinely churn up the sea, no less the engines which turn them.
I fail to understand your point, and the CD analog, (no pun intended). If camera manufacturers begin to make models with sensors that resolve better than 12 bits (indeed some do 14 bits per pixel today, then their raw files will likely reflect this unless the camera downsamples for whatever reason. In the meanwhile, it dosen't make much sense to encode 12+ bits of extra precision, per pixel, if it's not necessary. If your compression is good enough, and your sample size large enough, you might be able to regain some of the memory used for that extra, useless precision, but it's going to come at the cost of CPU, battery, and buffer memory.
With your CD example, it makes sense that some players came with 14 bit DACs, probably because people didn't want to pay for equipment that had 16 bit DACs, and let's face it, 14 bits and crappy DACs are more than plenty for the pop music that most people play. Just the same, 8 bit JPEGs are good enough for most people, so that's what they get.
For instance a Canon CR2 on a 5D, 30D, and Mark 2 are all different and not interchangable. You don't know if the camera manufacture will suddenly drop support for a particular implimentation, leaving your older files in a lurch.
While true, we have both open and closed implementations for rasterizing raw files from just about every camera from just nearly every manufacturer. It's doubtful that anyone will have great difficulty to access their camera generated negatives anytime the foreseeable future.
The format isn't especially specialized (well, in a way it is), however, any piece of equipment taking an image and exporting an EXR file as a result is bound to be pretty specialized (and expensive) in the here and now.
So, what do you think, is DNG going anywhere as an interchange format? Adobe's really pushing it, but it just doesn't seem to be taking.
Well, I think it's an alright idea, and being based on TIFF and all, it should be pretty easily workable. I think the disadvantage is that a camera supporting DNG will output 16 bits per channel, even though most of the sensors in the industry will resolve 12 bits, at least I think that's how it works, unless they've massaged TIFF into doing 12 bit pixels, and to be honest I'm not all that familiar with how DNG works. Anyway the point is file sizes may be bigger with DNG vs. RAW in some situations.
On the other hand, my experience messing around with DNG is that file sizes are often smaller than my 20D's native RAW files, so they're doing something right, which makes me wonder how much processor time and battery power a camera can afford to put into compressing files this much.
You said "Not going to end jpg - everyone dissatisfied with JPG is already using RAW.
Yeah, they are using RAW data in the manner you outline, THEN they use TIFF for storing and transporting these images. TIFF is the industry de-facto. So, MS's little format might compress data better. It's not likely going to do much that TIFF can't be adapted to do.
Not to disagree, because I code all day and type very quickly, but have you seen most teenagers with a cell phone?
Yeah... But mark my words: within ten years time all these teenagers who frantically text on their phones all day long will suffer badly from RSI, and it'll be all over the news. Ergonomically, it's got to be one of the worst things to do to ones hands.
Distilled water in a cooling system is no better than tap water. Sure, you won't have an amount of ions that will be signifigant to conduct electricity...for the first day, that is. The particles are still going to come off the metals that compose your system, and then you're on the path to being hosed by galvanic corossion.
The key is to not using dissimalar alloys in your system. An aluminum block and a copper radaitor are going to cause problems, unless you use some of the products out there which combat. That's the real key. Pure water is even more corrosive than tap water. Ideally, you want your alloys to be as close as possible, simply for the fact there will be little electrochemical potential.
Yeah, looking at the demo pictures I see this is basically replacing noise with blur.
I was thinking about this recently, and I think what we need is a digital camera which can somehow take multiple short exposure shots one after the other and then combine them into a single photo. The algorithm would have to be smart enough to detect movement of both the camera and the scenery in-between frames, so we're talking advanced software, but it does seem possible.
I was not entirely impressed by the demo pictures, but it does seem to be a worthy start, especially for an OSS program. I am personally used to a neat little utility called Neat Image, and the results I've had from it have been nothing short of amazing, and entirely worth the price.
Anyway, I'm not entirely sure what you're getting on about with the software you speak of. If your subject is part of a fast paced scene, it's going to be very difficult if not impossible to merge the frames with current technology. If your subject is relatively static, automatic exposure bracketing will provide you with what you want, and all the semi-pro DSLRs out there can do this.
Stupidity is positively endemic to the culture of any university.
Well sure, so it is to everything, or at least it seems that way sometimes. I can say that my university experience was mostly devoid of stupidity. How far from the norm my experiences were, I cannot say.
Uhhh. Why should he bother changing university (and job) over IT email policy? Even if he doesn't like the email service, doesn't run Windows, and won't ever use it - why does that warrant transfer to a new school?
I would probably think about it if I were in this position, and weren't especially attached to that school, and here's why: an action as poorly thought out as this one is surely not the only silly thing the school has done or will do in the near future. In other words, stupidity is almost positively endemic to the culture of the university, and only it's going to get worse before it gets better... The only way it's going to get better is if customers (students) vote with their money.
Plus, I just wouldn't want my professional reputation to be tied to a university with a habit of making idiotic moves like this, most especially if I were attending for some technology related degree.
If the problem is really depression . . . you can't play a game, distract yourself or even "think" yourself out of it - rather like expecting a drunk to become sober by performing some task or "think" themselves sober.
And why not? We humans have to think of something before it can happen, you know.
Maybe depressed and drunk people just aren't very good at thinking, and everyone else who was previously depressed or drunk at one point have already convinced themselves that they weren't inflicted by these problems?
Wake me up when Mazda comes out with a turbo-diesel rotary (Wankel) engine. There's nothing like high RPMs with a nice torque curve.
Moller, the guy behind the Skycar and Supertrapp mufflers was awarded a contract by the Army to research developing a small rotary diesel some time ago. They had limited success, the engine they developed burned diesel fuel, but was spark, and not compression ignited. It didn't develop enough compression to operate as a diesel, the apex seals routinely shattered at those pressures. Engine speed was significantly impaired because diesel fuel burns much more slowly than gasoline. If it rotated too fast it would blow diesel vapor all over. The problem is basically the same with cylinder engines.
I think your best bet for something which is diesel powered and having high RPM and high torque is to wait for a diesel hybrid with a decently sized power plant. Electric motors are well known to exhibit both of your desired characteristics, and the diesel can purr away all day with no worries >:)
