Several SSDs are claiming 1TB-5TB per day written every day for 5 years before failure. Even for the 5TB per day one, it was a 512GB hd. How many people are going to write 5TB/day to a 512GB drive?
Every year, this number goes up. Even if drive density isn't rising, the controllers are getting much better and latency, sustained read/write, and longevity are all getting better really fast.
Kingston even had a video of them taking an in production SSD, tossing it in the air, and nailing it with a baseball bat to launch it several feet. It still worked. You walk too hard next to a mechanical HD and you could break it... well, with your heals I guess, but still.
A 256GB SSD with a multi TB central home server will do me just fine.
The i7 quads are completely CPU bound, even with only dual channel. When you add tripple channel, even a 6 core can't stress that yet.
Memory latency/bandwidth is a non-issue for Intel right now.
The biggest issue for core scaling is the current cache coherency model. Any time several cores are trying to access the same memory locations, if one core makes a change, it has to update that change to all cores that reference that address in their cache. well, actually flags the cacheline as "dirty" and it's updated when accessed.
Get 64+ CPUs all using a few addresses for thread sync, then lots of cache updates start flying all over and slows the system down. Even MS claimed they could have made more threading tweaks to Win7, but they didn't want to invest too much into a certain optimization only to have AMD/Intel make conflicting changes to how thread syncing will be done going foward.
Mapping My Documents has nothing to do with sharing and everything to do with central access. Unless you give access to others via the ACL, no one is going to go snooping in other people's My Documents.
"unnecessary strain on the backbone of our network"?? I'm in a small/medium business(slightly under 1000 employees) and all of our network shares are on the SAN. With ~35 database servers, each with *at least* one 8gb fiber chan connection to the SAN. Our newest DB server can almost max out two 8fb fiber cards at the same time and the SAN usage graph doesn't even register activity.
Internal bandwidth is cheap, storage is cheap(well, kind of). How can your "back-bone" get saturated so easily? SMB file sharing should be almost nothing.
I actually remember quite a few times in the past when Linux had root elevation exploits. The Linux community just replied with "don't let people you don't trust have console access".
And some quotes from the above link
"regularWindows users can’t exploit them"
"if you can upload ASP web pages with exploit code to a MS Internet Information Server (IIS) 6, 7 or 7.5 running in *default* configuration"
It's bad, but not *as* horribly bad as the title suggests.
A properly locked down Windows machine should have been mostly immune to this anyway.
I still love how *nix naturally allows individual services to run under different users while Windows defaults to more of a blanket user to access everything. Windows is better than it use to be, but still not quite there.
My router didn't allow internet access until you changed the admin password. After that, you could change it back *if* you wanted, but it was just that way for the first time setup.
Same for the wireless. The AP on my router came disabled and required an AP password entered before it would enable. After enabling it with a password for the first time, you could remove the password and make it insecure/open.
Now I just need DD-WRT to stabilize for my router so I can use the IPv6 my ISP has..:-|
I think the way BC2 was released was fairly decent. They have two server modes, one where it connects and validates against EA's central server and the other where it doesn't.
But... if you don't validate against their server, you lose all the automated anti-hack abilities, which is updated by their central server anyway.
So, this means on servers where people can play illegal copies, there are lots of hackers and the play experience is reduced.
I'm not saying that everything is perfect, but it does "deter" pirating and/or "encourages" purchasing the legal version.
nice to know about for BR.. I was under the impression if was higher, but like you said, probably a "max"
On another note, Cable/Broadcast TV looks like crap. Pixelates on high screen changes because of the low bitrate.
Since we're talking about the future, we should expect no less than full BR quality, not crappy current cable streams. Remember, this is 10 years in the future. People are going to want this 1080p 3D videos, that's two HD streams to feed both eyes. Slap on 2160p and you start getting up in the 100mb/stream easily.
4mb/s is crazy low quality. BlueRay is ~40-54mbit/sec. When I can have 3 TVs receiving streamed blueray, then I'll be happy until the next media upgrade.
"[...] pick up a book on database design and start to tinker."
That's about it. You need to learn to think like the DB.
3 things you need to know. 1) What information you need to store 2) How it related to each other 3) What kind of queries do they need to run against it
Table structure will affect what kind of indexes you can use, and the indexes will affect the performance of different queries in different ways.
I didn't know a final project was that easy to cheat on.
In order to graduate, I had to get a B or higher and 40% of my grade came from my team, 10% from the teacher, and the other 50% from the company we did the project for.
As far as I can tell, this would be for entry level students and entry level students don't have a degree from the school yet.
I'm not saying these scammers are "correct" in any sense, but damn... many of these scams are so stupid, it's like a 30 year old putting their hand in a blender and saying they didn't know it was going to hurt them.. I mean.. WTF?! really?!
Hi, I'm some random person you NEVER heard of before and have no reason to trust.. Give me money... OK..
OMG!! I was scammed!
I'm just saying, a lot of these people get what they deserve. Stupidity is no excuse.
Some scams are quite elaborate, but that's the corner case.
I would compare scams to Virii on Windows. Almost all people who "randomly" get virii, are actively clicking OK on every pop-up and downloading and installing every program that crosses their cursor.
Honest officer, the tree jumped out in front of me!
"Scamming old people with Alzheimer's disease out of hundreds of dollars does not serve a social purpose."
If someone with Alzheimer's has access to money, someone just F'd up.
Most scams prey on people with NO COMMON SENSE. I mean.. really.. "Hi, I'm a long lost grand child of yours and I need $1000 to get home".. uhh.. OK...
Really, this is 95% of scams. The other 4.99% is "GET RICH QUICK!!!". It's the very very very small percent left over that is actually hard to tell if you gave any thought to it, like this guy http://en.wikipedia.org/wiki/R._Allen_Stanford .
"You are a moron" - not good debate etiquette and is a good way to reduce the effectiveness of your point.
P.S. My numbers were pulled out of my ass, but I'm sure people know what I mean.
Your logic is perfect. These scammers really do serve a purpose, as do rapists. If only their "victims" were acting less sexy and vulnerable! This will provide them an incentive.
The only difference is the rapist MAKES you do something, the social "leech" just tries to persuade you.
The logical course would be to tax money based upon where it is EARNED, not where the company resides.
To go along with this. Tax earnings made in the USA, then give tax breaks for every person that company employees in the USA with extra incentives for R&D positions.

"I don't have time [to] spare[...]and I will have to pay more attention to system requirements of games for a while"
yeah, so little time. can't break away from games for 15min to figure out which CPU is best.

what about power supplies and LED lit LCDs?
I have a namebrand $80 psu that's only ~8 years old and it had a power factor of ~0.8. My new PSU has a power factor of .99+
My old PSU was ~75% efficient max, my new one is ~85-89% depending on load
LED backlit LCD's consume about 1/2 the power of a florescent lit one, not to mention the lack of Mercury.
My ati 4850 consumes ~60watts idle, the ATI 5770 I plan on getting soon will consume about 20watts idle.
For servers, the biggest power draw is going to be HD/CPU/PSU, but a "green" version of any of those can add up really fast.

context switches are expensive. You're better off comparing the whole string to make the times similar than sleeping the thread.
A context switch is typically 1000+ cycles. Those same cycles could've compared a VERY long string.

Win7 is faster, more scalable, more stable, MUCH less bug ridden, better security, and supports new tech...than XP
By your rankings, Linux must be the worst OS out there and Windows ME rules with an iron fist.

My brain feels like mush after a week of no computer. I have to constantly be thinking about something, I can't stand "just laying around".
I find playing games that involve lots of strategy keeps me "feeling" sharp.
Since the breaks are 100% electronically controlled.... how do they work when the car has no power?
you build out to support peak usage. Average server usage can be quite low, but you can't have your system coming to a crawl when peak hits.
Theorycrafting in any complex mmorpg usually is very math and scenario heavy.
But the real question is, how many people actually try to be the best?

60-70 hour weeks?! ewwww..
If I work more than 50 hours in a week, I get sent home.. -- salaried
I almost never see over 40 hours.
Even during crunch times. Work more than 60 hours and I'll get sat down an asked why I'm working so much and how I plan to reduce my work load.
I didn't know a final project was that easy to cheat on.

Best you learn to understand context. His "definition" of "everywhere", works just fine and is easily understood.
