/64 is the standard and if the ISP doesn't use it, it could break stuff. They would have to order custom Cable/DSL modems since all suppliers will be following the/64 rule.
Or ma'b it's because pushing a 400MB patch to 12 million players is almost 4.5 petabytes. That doesn't include their web hosting or battle net or the fact that you can now download any game from their website now. Ohhh, I want to re-install D2, time to download 4GB from Blizz. Opps, need to re-install WoW, time to download a 2.5GB installer then another 1GB of patches. Hey, you should try out WoW, you can download the client from Blizz. Now there's 10 more people downloading and patching almost 4GB of data from them just to "trial" it.
If you want to be anything near practical and scalable, you need to use P2P.
oh, and that 400MB patch pushed out to 12mil clients would completely hose the internet backbone for about 1 month unless they spend a few trillion dollars to replace all those crappy OC192 connections with something that can handle that much data.
Then you reply: "But the difference between your web pages and mine are the difference between a Space Shuttle and a bottle rocket. Both have rockets, don't they?"
I completely forgot about this. Last year Turbo Tax let me fill out my taxes based on my company. All I did is select my company from a list and it auto-filled all of my data and I checked it over.
nvm. There was a different out of band critical update that didn't require a reboot. This one did need a reboot to take effect, but it didn't force it.
You only need a hand-shake at the beginning of a connection. Maybe they need to let a connection stay open a configurable amount of time set by the web admin. I could see a connection staying open for 1 minute and that would cover a lot of rapid clickers. If I spent more than 1 minute on a web page, waiting 1 second for the next link to respond won't matter much to me.
Or ma'b we need a new system. Here's an example of something that would help, but not very transparent since browser and web service would have to work together.
After a secure connection is established and right before it drops the current connection because it's done transferring, create an symmetric key, send the key to the client along with a GUID/Token. Next time(make these tokens expire after 15min or something) the client attempts to connect to the same web server, the client sends this GUID/Token in clear text and all data after this token is encrypted with the previous agreed key. If the key+GUID pair is rejected, start over from scratch and just do a new hand-shake, otherwise keep on truck'n. Obviously the server would remember which GUID is attached to which key, and the GUID+Key would expire the instant it's used.
The above example would eliminate a hand-shake on every new secure connection by the same client and wouldn't add to much extra load to the server because looking up an indexed table of GUIDs to find the key attached would be easy.
What is the CPU overhead for Encryption? My brother just installed Truecrypt on his 3.5ghz i7 and it says he can do ~510MB/sec of AES-256.
Assuming a 100mbit network connection, 12.5MB/sec would be about 2.5% cpu. If it was a dual socket server, it would be about 1.25% overhead. If the 100mbit connection was shared by 10 machines, it would be 0.125% overhead per machine.
My statement makes the assumptions of similar CPU performance to my brothers 3.5ghz i7, ignore decrypting incoming data which would be less than outgoing, and uses encryption on the filesystem compared to HTTPS, which would be quite different depending on how it's implemented.
AMD/Intel both will have HW accel'd AES in the next chips which both claims about 40% improvement, so typically sub 1% overhead I would guess.
Similar thing I heard. I've seen people talk up HD storage like it's dirt cheap to. It might be cheap for consumers, but not a decent hosted setup.
My company recent bought an effective 16TB of SAN storage, costed $120k. You ask someone how much they think 16TB costs, and they'll be like "hmmm.. $200 for 2TB, so $1600 for 16TB."
Some people also say memory is cheap also. It's cheap if you buy small amounts of it. a 2GB stick is a lot cheaper than an 8GB stick of ECC server grade memory. One of the server guys told me about a recent computer they built. A standard dual socket i7 with 32GB of ram and all the fixings, so ~$10k. They wanted to see the costs for upgrading to 192GB since it was an option. An extra $50k. Not only did it require much denser sticks, but it also required CPU and socket upgrades since the lower end CPUs and mobo didn't support those densities. you can't just go.. "hmmm... 6GB for $100, so $3200 for 192GB".
Now you need a failover computer, so instantly double your costs.
When I got hired on, I saw the "global" option for all the different portfolios. Figured with the USD dropping, be a good idea to set my money on more global. I'm in a VERY small city, like 8k people. A local bank manages the 401k for my company. The bank said they would be removing the option of several large companies from their portfolios. Few months later, most of the companies removed from the options crashed from the bubble. go go small bank!
Corn has always been GM. That's how corn was made in the first place, corn is not naturally occurring. I felt this went along with your "GM corn" comment..:p
Man I'm lucky I took longer to graduate. Local large company did all of its hiring during end of Spring semester when most people graduate. I missed that. But I graduated in Fall and got picked up by another company 3 months later. Turns out the other company did lay-offs.. w00t.
Then the market crashed.. good time to start my 401k. My 401k started about 2 months before the crash. Within 8 months and investing $1k into it, it's worth $6.5k. That's a good return me thinks.
"The instruction decoder is the one part of a CPU that you can't turn off while executing anything"
The i7 can disable its decoder. Since the decoder turns x86 into micro-ops, if the i7 detects a loop, then the decoder won't be used until the loop ends. It'll turn off the decoder during these. But yeah, too many deprecated instructions that should just be dropped.
They want to wait more because in a few months there won't enough free IPv4 addresses left to give every citizen an IP address, then they'll have to wait for IPv6 before rolling out.
I remember reading an article about sheep and virii. Some type of sheep use to have a virus that use to be bad for it. Even though this virus was bad, it did have one good attribute. It reduced the chance of a miscarriage and did it better than another "native" gene.
It so happened that this viral infection reduced the chances of miscarriages enough that at some point the virus stopped being bad for the sheep and they had a better chance to reproduce.
Now days, if you neutralize the virus, the sheep will always miscarry since the old gene got silenced/removed in favor for the virus.
The sheep and virus evolved to live together.
I read this a LONG time ago, i think it was in Discovery mag or something, but I can't remember much more than the idea of the story. The details might be slightly off, but the summary is the same. And they did talk as if the virus was still actually living in the host, not just select genes.

That's how Japan does it. Many ISPs all sharing the exact same lines. Changing ISPs just means changing who you pay is all.
But then you see people in Japanese forums downloading 45MB/sec from 3 seeders on BitTorrent.

nvm. There was a different out of band critical update that didn't require a reboot. This one did need a reboot to take effect, but it didn't force it.
I use Win7 and it installed then said it was done. No reboot or prompt/question to reboot.

I remember that. Never got too far though, but it's still an ass move to even attempt.
"2. Encrypted data, if the algorithm doesn't suck, is not easily compressed."
that's why you compress it before you encrypt it
