Would a large bank of these be what's needed for a "smart" grid with fluctuating power levels from green energy like Solar/Wind? Large dump of power on the grid, charge the batteries, wind stops or a cloud and now you need to pull power out of the batteries.
Is there any inferred efficiency with the batteries if they can charge faster? Less resistance so less waste heat? Just asking.
I would see these being useful for hybrid cars. You can dump momentum faster into electrical storage, so the actual breaks get used less.
I'm not not a specialist of any kind, but I will repeat what my college professor told the class. The USA is consuming fertilizer at a rate a couple of magnitudes higher than it's being replaced. We use quarries to supply minerals to add nitrogen to the soil. We consume something like 60 cubic miles per year. Once it's all gone, our current ways of farming will crash.
That 60 cubic miles of earth is not spread out from all over. It mostly comes from a few select areas, so those areas are depleting relatively fast.
Again, this is coming from memory and that "60" number could be a large +- percentage of error, but the idea was conveyed that we were consuming the resource waaayyy too fast.
The thief is not blameless, but the thief is a variable that you can never get rid of. Arguing about the thief is a moot point.
MS is the person who builds the house and the security system, the owner is the person who paid for the house, and the thief is the person that is trying to break in. Current MS OSes are actually quiet secure. It is not an issue of the thief picking the lock, but of the owner willfully handing the thief the key to get in.
A long time ago, a person who put their hand in a blender got weeded out of the gene pool because they could not eat. Now days, society picks up the bill and floats that person for their ignorance.
Common sense is all that is needed to thwart 99% of virii/malware. Most current malware is about social engineering, not security flaws. The only way to stop malware is to remove control from the end user. Most end users are lazy and willfully ignorant.
My mom got her first computer ~2 years back(she's almost 50). She got lots of malware for the first few months, so I told her how people try to trick you into running the software and that's how it's getting on her machine. I told her, if you don't know what it is, don't install it. She hasn't had a single malware since my talk. She is almost completely computer illiterate, but she understands the social engineering part once I explained it.
All UAC did was prompt Yes/No. Linux Prompts for User/Pass. I don't see how Linux is easier.
UAC prompted when an application tried to change system settings. Seems lots of applications try to change system settings. I'm not sure how it is MS's fault so many apps wanted to mess with your start-up/drivers/system-hooks/etc.
Kind of like Bad Company2. When it first came out, UAC would break your ability to see your ping time. The issue is the devs decided to use raw sockets to calculate pings instead of just just using UDP or ICMP. Raw sockets require admin privs since you can see all data going in and out of the machine using them. Everyone blamed UAC for "breaking" this.
Virii are less like armed robbers and more like people who go around asking "Will you give me the keys to your house?", and then the home owner is surprised to come home to find everything is gone.
If someone willfully gives over the key to their house to someone they don't know, do you blame contractor who built the house for not adding more locks or do you blame the owner?
"And this is why MS decided LAST WEEK to turn off Autorun in XP by default. Duh. The setting that ANYONE with a brain has had switched off since day one"
Don't worry, Linux just recently added Auto-Run and has already been exploited. I guess Linux devs don't have a brain?
Yes, an over-generalization, but goes to show you that even Linux isn't immune to making the desktop more friendly without security issues.
The problem isn't so much Windows as it is the programs on Windows. How many times have I see an application that didn't need to change any system settings, but wrote to restricted locations "just because" which made the program require admin privs.
I see crap like this all the time in Dev forums: 1) When I try to write my log file to c:\Windows\System32, it gives me an access denied error. 2) Why do you need to write to System32? Why not Environment.SpecialFolder.ApplicationData or something instead? This way you don't need to run as admin. 3) No reason. So, running as admin should fix it?
Now, get these people developing for Linux.. yay
I've seen big name games not work unless running as admin because they decided to store settings.ini in restricted directories. Then we blame MS for requiring everything to be ran as admin.
An Intel Sandy Bridge on integrated graphics is quite snappy. I think you're a generation old on complaining. Next year's Ivy Bridge GPUs will be much stronger and should handle 1080p at ~30fps on most current games. Just make sure you set the quality to low. The current Intel integrated GPUs are getting 45fps in WoW at medium and can even beat nVidia 480 at converting videos.
I can't wait until I can switch over from Windows. All I'm waiting for is Direct 3D 11 support and fast stable graphics drivers. When I don't need to dual boot to play my games the way they were meant to be played, then I'm running on over.
until someone gets a warrant to string tap you. You'd think the string connecting the two cans is protected by quantum randomness from the string theory, but it is not.
Nice to know:-)
If it works as a unified memory, then 2GB per node and 30 nodes is going to be way more than 32bit addressing, but it would be great for distributed work. If each Node runs as it's own machine, then they will have to have a separate boot drive for each node and each node will have to have some sort of network connection to every other node. Should be interesting once more info comes out.
64bit memory range? Each node is going to have it's own memory slot(s). 120 cores, 4 cores per node = 30 nodes. If you plan to have less than 4GB of memory in this system, how small does each stick have to be when you plug 30 in? ~128mb. Good Luck finding a bunch of DDR2/3 128MB sticks to plug into your 4GB 120 core web server.
Anyway, each node needs its own local copy of the data it needs to serve up. If you web page needs ~256MB, each node is going to need the same 256MB of data duplicated, plus any extra overhead.
You can't expect all 30 nodes to access the same 2-3 memory slots; that would scale like crap. This is one of the issues you get when scaling via cores. Interconnection bandwidth/latency becomes an issue and you need to use local storage to allow fully independent processing. Once you start getting up into these ranges, you're better off thinking of each node as its own computer with a fairly high speed network.
The only nuclear setup I know of that doesn't "melt down" is the pellet design. Instead of rods, they use small pellets encapsulated in graphite. Too much surface area to melt down, even if all the coolant was removed.
Much more expensive, but quite a bit safer. You also get an easier clean up because the graphite shells keep all the nuclear material contained.
As for wind, it is unreliable. Power grids are not meant for fluctuating supply. Wind can augment a stable power supply like nuclear/coal, but it cannot replace it. You still need a "smart grid" if you plan to have a large scale roll out of Wind/Solar because a sudden breeze would overload the power grid if you have too many Wind generators, and a sudden drop in wind would cause a brown-out. Power plants cannot change output very fast and a bunch of "Green" energy creating huge power spikes would burn out lots of parts and it would cost more than nuclear in the long run.
Correct me if I'm wrong, but my understanding is that the microwave radiation emitted by cell phones has been shown to actually be beneficial to simple organisms like earth worms in low dosages while x-ray radiation has been shown to be bad for anything that uses DNA.
aka, x-ray is ionizing radiation while cell-phones/wifi/background-radiation is not.
I don't think we can compare radiation to radiation without them being in the same wave length.
Again, I don't know a whole lot in this area and I'm interested in other responses.
I think it was said that something like at the age or 3, kids start to become self aware. After 3 years of running, SKYNET may learn to take over the internet and can recognize it's own reflection.
Figured it out. The ~36 hours was with the non-SSE client. The SSE2 client runs near half that time, so closer to 100 times faster. With my i7-920 rated near 30GF and my ATI card rated near 2.75TF, this would be about in line(2750/30=~90). Not all GPU clients run this much faster as not every work load scales perfectly, but this one client really shows off how much faster a GPU can be.
My GPU has 1536 shaders, consumes ~220watts. My i7 has 4cores/8threads and consumes ~130watts.
On several of my distributed tasks, the SSE2 version takes about 36 hours on one core, or about 6 hours per task average if using all 8 threads(assuming an optimistic 50% scaling from hyper-threading). My GPU, on the same work units, takes only 1min 40sec. The GPU is about 216 times faster and slightly under twice the power. 60% more power draw, 21600% better performance.
I wouldn't compare GPU vs CPU for power draw. You have to compare gflops/watt.
My wife's phone does not have a "data" plan, but she does have a text plan. Last night, she sent a text message to my gmail account and it took ~1.5-2 seconds from the time she pressed send to when my computer dinged that I received a new email. (No pics or video in the text message though)
I can't see how it could take 5 seconds to setup a connection without having signal issues.
Heck, it only costs me $20 total for unlimited text/pic/vid messaging on up-to 6 lines. In network, out of network, it doesn't matter.
If I wanted only a single line, I could pay $70/month for 200minutes of anytime, but 5GB data and unlimited texting (nation wide). That also includes free incoming minutes 24/7 (nation wide), and free minutes after 7pm(nation wide) and free minutes on the weekend from 7pm friday to 7am monday (nation wide), and free in-network calls (nation wide). My coverage map is extremely good and has much much better rural coverage than AT&T/Verizon/Sprint.
If you want to talk about costs, most companies charge more for texting than it costs to rent time from the Hubble telescope. I'm not sure how you can defend these practices.
Yeah, I thought it took 2-3 years before MS finally had a year that "broke even" instead of having a loss. But after all the recalls/etc are added in, how much did this set them behind?

I can't elevate my esteem(in computing) for Carmack without overflowing back to 0. He is a genius in his field.
I find it funny that many Wine developers said D3D11 is easier and more structured than OpenGL. Even OpenSource developers like DX over OpenGL.
I think it was said that something like at the age or 3, kids start to become self aware. After 3 years of running, SKYNET may learn to take over the internet and can recognize it's own reflection.

Yeah, my ATI card does about 2.5TF, but the Fermi blows the ATI cards away with DP flops.

I know the 360 cost them a lot.
unlimited text/pic/video on all lines in my family plan for $20 flat. Not per line, account wide.
Any line with the 5GB data plan automatically gets unlimited text/pic/video. Data plan is $20 per line.
text/pic/video is free incoming no matter which plan I take.
