Like any new technology, it will likely drop in price over time, along with the price to replace parts. Perhaps it would be wise to wait and see what other theatres do, perhaps you are correct and the cost of these new systems will put some theatres out of business, thats when you should buy their semi used projectors from them. If it's not all that bad and digital projection becomes the defacto standard for movie giants, the price to purchase one may have dropped so you might win out in that sense too.
How'd something like this get slashdotted? Shouldn't a web site that deals with quantum mechanics, astrophysics, supercomputers, wireless networking standards, etc. be beyond "jpeg" compression? Thank you for wasting 5 minutes of my life and telling me that you can compress jpegs.
Sorry if this seems like flame, but someones got to say something.
I went to the link in the topic and got a "Server Busy" error... I think the perfect website probably should incorporate dealing with high traffic / efficiency as well as good visual design =)
Hello, I Work for Morrison Hershfield Ltd. We have been contracted out by Axia to handle much of the Construction managment, site aquisition and logistics of this job. Alberta is being divided up into Geographic regions each with several locations for sites in them (I belive there are 50-100 or so). I'm not sure as to the details of yet (The job has just begun rolling down here), but each of these regions is divided up into several sites which need to be setup. Perhaps the document is off with the 422 towns. I belive it would be more accurate to say 422 locations or nodes for service.
I'm going to assume that for now the author goes for something using Javascript:
#1. Javascript is extremely slow. It's also interpreted, not compiled. Code optimized and compiled for a system can be a hundred times faster.
#2. Coding anything usuable for this type of application would require a good bit of code to be sent via javascript.
#3. The amount of processing it would take to:
A) Generate the web page to send to the user with the appropriate Javacode + whatever the user needs to process
B) User's computer to interpret the Javascript, execute the code, send back to the main host computer
C)Host computer recieves the data, decides where to store it, what to do with it etc.
And for the code to run and NOT affect the user significantly (meaning the processing done wouldn't be very much at all), all in all would likely require far more processing than it would if it were compiled on a server just running by istelf.
All in all it would be very inefficient, and probably faster for the server managing the data and generating the pages to process this information on its own.
Rogers is basically across most of canada. In a few provinces there are other cable providers. Rogers also has to compete with ADSL in most areas now. I believe there should be something in place so that bandwidth can be fairly distributed for the most part. Where the problem lies in how they do this. For the most part, most of the peak bandwidth times are in the afternoon. This is one of the few times that its actually noticably bad. For the rest of the day and night you can do just fine. Now for someone who downloads huge amounts of data in very off hour times, it seems very unfair since im really not impacting other users. Bandwith charges, if required should be not only based on how much traffic is done over your monthly limit, but should be be a higher rate during peak hours since service degregation is only noticble in this time frame. Many of my friends are on Rogers, mind you I myself am not, I'm using a very nice local cable company called dccnet =)
The centrifugal force of an orbiting satellite would compensate for any pull from cable below. In the original NASA idea, ideally it would be the best case scenario if the entire weight of the cable was supported in geosynchronous orbit. This means that at the base of the structure there would be very little force pulling either up or down on the cable, since it would "support" its self.
That measurement is based on a cylindrical shaped cable. A conical cable would require far less cabling. A cylindrical cable would require a huge amount of ballast at the other end. Well over doubling the length (4-5x). Also, this does not take into account the possiblity of using a large near earth asteroid as "counterbalance". Saving a small amount of mass close to earth will save massive amounts of ballast many kilometres up.
I hope I don't get modded down for this idea like I always do but here it goes anyways..
I've read several books which include the idea of a space elevator, and one of the key problems had to do with bringing that much cable to space, and the strength of the cable to stay together. The closer the cable gets to earth the harder the pull, the further out the "satellite" holding the cable in geo-synchronous orbit has to be. Instead of bringing the cable down to earth.. or putting it atop a very high tower, why not create a platform 50-80,000 feet up for planes to land on. This would save very large amounts of cable from being created, the satellite wouldn't have to be nearly as far out either to compensate for the gravitational pull from the cable below. Also, to compensate for the excess weight of the aircraft and payload while landing, the satellite holding the cable could move up and down to balance any weight added or removed to the cable.
Now, having a shortend cable would have added benefits too, in the event of a disaster, normally a cable attached to the earth would wrap around the planet several times causing an incredible amount of destruction. This could be minimized with my platform idea. Imagine something colliding with the cable causing immenant failure... why not create sections in the cable to automatically break off in the event of a disaster, this would minimize the amount of cable falling to earth, and the remaining cable would be either ejected into space, or depending on how an object hit, its possible the upper section could re-establish a geo-syncronous orbit after losing much of the cable.
Any pysicists out there able to agree/disagree with this? The tether would also most likely have to be conical in shape, thicker higher up, and thinner below to minimize the amount of carbon tubing used in the elevator.
I've created a very simple security system for my home computer, mind you it's probably not exactly what your looking for, but it does the job.
I started off with a Logitech QuickCam. The camera I had was of horrible quality, but enough to make out whats going on. Next I downloaded the SDK from Logitechs website and within 30 minutes or so, read up on their documentation for the SDK and created a very very simple security system program.
Esentailly all it did was monitor the camera using a built in function in the SDK for movment, once X amount of moment was detected over Y amount of time, the camera switched on and started filming until the movment stopped for a specied amount of time. The files were avi files stored on the local hard drive, and didn't take up much space at all. Now I would suppose you want a much higher quality system, so go out and buy a bit nice digital camera. At 5-10 fps you can fit quite a bit of compressed video on a computer. The only downside was that it performed very poorly in the dark.
So your saying that using 802.11 you can sniff the entire network around you? Isn't this a HUGE security risk? Especially at an airport. I work in an office where alot of our employees (Most of them suits with $5000 laptops only used to edit work documents at 10wpm, browse the web every now and then and play solitare for half the day), and unless you have a very nicely locked down computer and/or a local firewall up on that PC, alot of Companies would not want their laptops in such a public area without proper security. If you can also sniff the network it means you can DOS it too. Most of the bandwith will probably be wasted on the wanna be haxor in the corner and kazaa downloads. Suppose they catch someone flooding the network with useless packets, how do they go about catching them? Kindly ask everyone in the room to give them their MAC Address?
I wish airports would look into these things a little bit more. Coming from the private sector, 250K sounds pretty steep too.
The FCC has this posted on their site describing the 3G bandwidth Standards. Wireless 3G when implemented according to these fcc standards should allow for the following bitrates:
Capability to support circuit and packet data at high bit rates:
144 kilobits/second or higher in high mobility (vehicular) traffic
384 kilobits/second for pedestrian traffic
2 Megabits/second or higher for indoor traffic
I'm not too sure how you pulled out a real world speed of 20-30k. According to the FCC standards this "IS" considered a 3G network for High mobility Vehicular traffic, but is not the full 3G deal, as it does not support the other bitrates or the full functionality of a complete 3G Network. The system when fully implemented will allow for much higher than 20-30k and will vary depending on the location you're in. 3G isn't all marketing hype, it's a very large step ahead of our current network (when fully implemented of course). Unfortunatly we won't see the full benefits of the system for a while, until the products using 3G become more available, and companies such as Verizon implement more aspects of the 3G standard.
Everquest is a very successful "MMPORG" or "Massive Multiplayer Online Roleplaying Game". It takes place in a 3d environment and is very involved for a few reasons.
1. Because the game is online, and there are several thousand people playing on a server at any one time, there is a huge social aspect to the game. You can trade, talk, fight, form guilds.. or do anything you really want with other people.
2. The game follows in the paths of D&D style gaming, a much more modern version of old MUD games. You have a character which you play for long (and I mean LONG) periods of time to achive certain goals such as gaining levels, new skills or learning new spells.
3. The game is HUGE, when I first started playing everquest you could spend literally days exploring the game, and with new expansions being continuously added to the game, you can explore all sorts of new terrain, towns, creatures etc.
4.Challenging, the game forces players to use their brains in combat, grouping with other people to fight larger monsters is very very common, and there's always a monster bigger than you to fight, and fighting larger monsters means larger rewards.
I hope this sheds some light on what is everquest. If your thinking about buying the game, you need a pretty decent computer and have to play a small monthly fee to connect to the servers. Belive me when I say the game is very very addicting, some of my friends have dedicated over a year to the game, I myself stopped after a few months, had withdrawal symptoms and came back again. I've stoped since, but it wasn't easy;)
I would like to argue that saying that everquest has a 30% inflation rate per year can be somewhate misleading, since in everquest, a day in everquest passes every few hours so in a real day, you would actually be going through several everquest days.
If my memory serves me correctly, I belive everquest also has less than 365 days a year.. 350 or 300 or something like that. So staying true to the "virtual world" idea, I would have to say that statistics should reflect this too. Instead of a 30% inflation rate in a real year, It should be represented as a fraction of this.. maybe 1-2% inflation in an everquest year.
Cracking a Windows 2000 password may very well be very difficult to do, but getting into a password protected computer is actually rather easy. I have used before a floppy I downloaded off the web which contained a simple boot to a simplified Linux OS (Red had i think?) and had the lil floppy change whatever user accounts (including administrator) to a new password of my choice.
This whole thing is just like saying that all books are now going to be made with a certain ink that only works under daylight, but cant be read at night or indoors...
The way i see it, RIAA won't be able to stay competitive like this and will only hurt themselves. They aren't adjusting to the changes taking place out there, and eventually, they will fall.
The Recording industry must adapt to this otherwise some other company/association will find a way to deal with CDR's/mp3's while being profitable, and the RIAA will very easily lose its market share. Nobody will want to be with them because it would be like buying a book that can only be read in daylight =P
I understand that heating such a large area of well irrigated land would mean a very very large difference in the relative humidity of the air exiting the stack and the air in the surrounding area. This seems like another source of untapped engergy to me. A few articles have mentioned capturing the water and using it to re-irrigate the fields below, but why not go a step further and condense as much of the water before it reaches the end of the stack, so that it can perhaps fill an area inside the walls of the stack. Then have a turbine at the bottom and generate more electricity, and irrigate the fields further. A lightweight heatsink near the upper area of the stack would probably be able extract large amounts of condensation from the exiting air.
