If it is slowing down downloads etc a bit to make sure voip and other things works then I really don't care. As long "a bit" isn't slowing things to a crawl 27/7 perhaps like 20% during peak hours. Then I'd rather have a cheap throttled internet connection where time critical packages are getting through fast.
Of course in the real world until now, what I have seen from a few ISPs is that traffic like unencrypted bittorrent are barely getting through 24/7, until you force encryption on or run it through a VPN tunnel. My former ISP had a acceptable speed on my 20 megabit ADSL. But still when I forwarded all traffic in a VPN to a hosting center the speed on all protocols increased, torrent, http, ftp etc. even though most of the destinations had more routes to go through. So I guess in theory it could work but the implementation is often much different.
Well they never learn. I worked for some newspaper websites some time ago. We had our own ad servers which performed really well. But they decided not to keep them but to "outsource" them. I did tell them that they would have performance issues with that ad company since I had noticed that they were slow on other sites even when not in peak hours. And so we did manage to get performance problems with the sites. That was when I installed adblock for the first time, so when they called and said the sites was slow, I could see that they were performing well and document it with the tamperdata plugin.
It was ironic that we had templates for the websites that was without the ads ready for those occations where we got big news like that. Our servers could handle the traffic because I had scaled the systems properly. I also asked them if there were some performance / response time / capacity included in the contract but I never got a straight answer about that. The next step was they spent a great deal of time rearranging the templates so that the sites would render in the browser even if the ads had not been loaded.
I remember that one, great idea but personally I would never dare to do that except if the cooling water was a closed loop with some sort of heat exchange. I played with watercooling my pc some years ago before I got a laptop and it was great fun and many ways to keep your computer quiet. I made a combination of passive and active cooling. The outside radiator(this one in a larger version http://www.highspeedpc.com/Merchant2/graphics/00000001/Konvgroup2.jpg ) could keep the CPU and GPU cool when not gaming, and when the water temp got too high i had a smaller radiator inside with a fan(something like this http://www.hardware-one.com/reviews/senfu_water_cooler/images/radiator1-big.jpg ) that was controlled by a microcomputer would spin the fan up. It was really a neat little thing that could be programmed with different curved with fan volt and temperature on each axis.

Now that he mentions XBL: We here at Xbox Live make the users fiddle with hosting their own sessons and make them pay a subscribtion fee for it too! muhaha. Problems with lag, not being able to play with many users in one session, getting everyone disconnected when the host don't want to host anymore? We don't care, we don't have to, we are XBL.
I tried that latest Simpsons game demo. There were one funny thing about it and that was that Comicbookstore guy giving me points for finding an invisible wall
In my almost new house, they used cat 5e for the phone lines to all the rooms. They are all terminated in a connector in the closet with my cabletv amplifier, the natural gas heater, fusebox, heating control system etc. They also had prepared a RJ12 connecter for the DSL router(I think there is a frequency splitter inside) and I can see there is a pipe for fiberoptic cable put in the ground together with the power cable(so it will be easy to get 100megabit internet when it comes to my area later this year) So it was easy for me just to pull out the phone connectors in the wall and replace them with ethernet connectors and then put connectors on the cable in the closet and plug them in my switch.
I have been too busy working the last year so I have not had time for anything else than xbl games. But I just borrowed this game last week and it didn't seem so great to me. Perhaps because I only can play single player mode. (hate multiplayer since it costs money, I know noone who play games and I don't want to waste my spare time with random idiots on xbl:D)
It seems that many games these days focus on multiplayer and that's all great if you are into that sort of thing but not for casual gamer like me with little spare time that I don't want to waste on trying to connect to other people's laggy sessions hosted on their little DSL line and pay a subscription fee on top of that(nice going. charge people for having to run their own game servers).
I moved ½ a year ago from a apartment to a house. I moved from a place where I could se 20x SIDS to a place where I could see 2-3.
I had some connectivity problems with my different devices + a lot of bluetooth dropouts on mouse and keyboards.
When I was done moving in I got around to setup Wi-Spy to monitor for an entire day.
Channels 6 and 11 was populated with 2-3 access points that did not really make much traffic and I had placed my on channel 1. But all channels from 1 to 11 has a lot of signals that you need at tool like wi-spy to see, signal that looked like cordless phones, baby monitors etc and then cell phones with bluetooth enabled(on top of my wireless keyboard and mouse) And since I can use channel 13, I moved my AP up there even though it had a bit overlaps with the APs on channel 11. I got much better sustained throughput because of much less background noise.
I also monitored the 5 GHz band and it was dead quiet compared to 2,4. So I would move everything there if only my stupid airport extreme(old version) could run both channels at the same time, but I have 2 devices that does not support 5 GHz.
And IF you live in a country they sell to, which I do not. Nor does Microsoft with their Xbox. I have both a (hacked) appletv and a xbox360 on which you can rent movies, just not here.
Idiots. And even discovery and southpark has blocked parts of their site for viewing so I cant see videos. And so are most TV shows that are viewable on the net in the US.
And then they wonder why people still download. I have the money to pay for it and I would be more than happy to but no, no soup for you.
Everything these days are done on the internet from entertainment to doing taxes. In some countries the goverment are even investing money in internet connectivity to provide better connections to more people. But when you then start to charge by usage then you'll see people stop using it and development slows down. One would think it was better for the country as a whole to have people to embrace the technology rather than do bean counting on their internet traffic.
Being a European myself, I would say that the selling point for the iPhone must be the speed and the interface. Plus with appstore it is also a toy that you can play with for hours.
I could have used video recording more than once and MMS. It's not just teenagers that use these functions(although they use it 400 times more often with their 100s of SMS messages every day)
But when you have had many painfully slow Nokia phones and unstable phones with that Microsoft thing on it(had 2, even nokia was better), it is just so great to have a phone without lag in the interface, that does not have to be restarted every other day to make sure that it really is running properly. To me that makes up for the shortcomings of the phone.
If I had bought the standard phone from my provider(hi3g), I would have been able to send MMS, record video, make video calls, watch TV etc on the Nokia N96.
I agree, the iPod will be mostly dead in the future. Today people want a phone that can play music. At least that is what I am seeing when I use public transportation. Luckily for Apple many phones have had horrible music player interfaces(have not followed the phone market the last 2 years). Yes my Nokia had 2 gigabytes of storage, but the way to control and select music was horrible.
So Apple will need to make a cheaper phone+ipod, if they not want to get Sony'd.
Doesn't it have a button that can disable ABS , Traction / Stability control? In some cars it first kicks in when you reach a certain speed so you still have a chance of starting.
At work, one of our filters even blocked microsoft for a day or so. I get 3-4 blocked sites everyday just by looking at some links from Digg, Slashdot and a links from some newspapers. And this filter is only claiming to block dangerous sites. I am sure that they have blocked a lot of sites that had infected banner ads at some point but then have left them blacklisted to inflate the hit counter of blocked sites.
I'd say that they will have to wait longer to get failures. Try to have a server running in that enviroment for 5 years and then we will see. I would not do it without having some good filters. But for a test it is a interesting experiment.
For datacenters in colder climates, you can already get cooling systems that cools the water using air only when the temperature is below a certain temperature(just forgot the number). When it gets above that level the water gets cooled like you normally do. At work our old AC system was old and needed to be replaced and the new one does that. The outside temperature is so low that the water will be cooled with just air for half the year. It was more expensive to install since it needed more and bigger cooling units(I belive they also talked about bigger slower fans that used less power) when just using air but it pays itself in a few years.
Another interesting experiment would be to use the heat again. I dont know if the water temperature is high enough so that you could use heat exchangers, perhaps as the first step on heating ingoing cold water.
Indeed. I worked for a couple of years as administrator for a couple of large websites. We had our own ad system. I kept it running fast on some RH servers, making sure that it served everything quickly.
Then one day some in da management wanted to outsource our ads to one of the big known companies. And I promptly asked if they had made sure that the contract specified something about perfomance. Of course I had seen what you described about other sites being slow when using these banner companies.
So one day they changed the templates of all the sites to the external ad company and the load times for a page went from 4-8 seconds to 18-30 seconds before the browser were done. I always checked the sites in a browser even though we had some external companies monitoring the response times.
And then I sat waiting for the call that I knew would sound something like this "the sites are slow, do something".
So I got my ammo ready and made some speed tests in firefox with Adblock+ and Tamper Data, which clearly showed that all the load time was the external ads.
Of course I had to be a BOFH about it for a couple of minutes when they called and said stuff like "there is no problem" and "I get fast load times here".:D I mean I did tell them that it would happen
Then of course I asked politely again if they had some sort of performance / response time written into the deal they signed and then mailed them the results of my speed tests which clearly showed the problem. I also sent at mail to the web developers that gave instructions on how they could make the tests themself.
I then continued running adblock+ because it was hard to maintain the sites and find problems when there were elements on the sites that could not do anything about.
The sites were quite slow for many months ahead but it went from all the times to peak hours. it annoyed me because the system I had built could handle the large load, even 9/11 like events. (though everyday traffic now was larger than that day and big news didn't make the same type of spikes perhaps just 4x normal.)
I know that today it is not just geeks like me that notice that "the internet" has been slower. Friends and family sometimes comment on that it seems that browsing is slower.
Most people are not sitting on dial-up or ISDN anymore(I pity the ones that does) and the designers make pages that have way more data on them than before. I tried a ISDN backup line I have, about a year ago when my ADSL2 went down. I powered on the router and thought, "hey this was not all bad if I run 2 lines the speed will be acceptable". Wrong. even with adblock+ on it still took 60-120 seconds to load some pages, with all the images, and 1000 objects.
Me too, it takes a couple of hours and then I was able quickly to click [YES] to all the popup windows about something wanting to do something. I don't even try to read or understand it because often I have no idea what the program does, what it means if I say yes or no. Although the times I answered [NO], stuff stopped working.
