Take a look at the IPv4 packet structure. Where do you plan to add these octets? Don't tell me you're going to change the format because that will break backwards compatibility and would be no different than just using IPv6, minus the confusion of having a similar format.
While a 1MB frame would be nice for reduced routing overhead and increased throughput, the added jitter would be horrible. Great on a LAN, bad on the i-net backbone.
"Passwords short enough to memorise are now short enough to crack in many cases. See recent article about hash reversal with GPUs."
A 14 char password, would take ~ 300,000 years to break at a rate of 100 tril comb/sec. GPUs are still useless for breaking a good password.
The most recent GPU article(past month) I read had GPU clusters in the billions comb/sec and would cost thousands of dollars. Even with a crazy high assumption of 100tril/sec, it would still take a long long long long time.
If the attacker assumed a 40 char alphabet and you used even a 41 char, they would NEVER break your password.
The attacker knows nothing about your password, so they have only a few options. Use a limited alphabet like all lower case and no specials, which means dramatically faster brute forcing but anyone who uses even a single special char or upper case will be protected from you. Or they can use the full alphabet and take a very very very long time breaking everyone's passwords.
The problem with a lot of password theory is it assumes the attackers knows something about the password. The attacker typically doesn't know you're using a phrase of simple words, they don't know what your entropy is or how large your alphabet is. Assuming the dictionary attack didn't work, all they can do is brute force and go through EVERY combination. Use a simple word, throw in an upper case somewhere and toss in a special char, and add another word if you want to make sure you're at least 12 chars.
"Blueplanet[69]" is 14 chars. The attacker doesn't know anything about my password and it won't show up in a dictionary attack. It would have to be brute forced.
You know why the above example is safer than "A5#[z~];wLr^0@" ? because "B" is higher than "A" in the ascii table and assuming an incremental brute force, it would take longer to make a match.
A 90 char alphabet is considered the pretty much the full one. 90 combinations per char and 14 chars, that's 2,287,679,245,496,100,000,000,000,000 combinations. divide by half for average chance to hit in top of lower portion of the range, 1,143,839,622,748,050,000,000,000,000 combinations. At 100 trillion combinations per second, it would take on average, 362,709 years to break a 14 char password assuming a search space of the full 90 char alphabet. If they didn't assume the full alphabet and someone used even one char outside of theirs, they would NEVER break the password.
Another option is for the web site to use bcrypt to hash the passwords and make it take 50ms per hash. Even simple passwords would be fairly safe if your DB got stolen.
What are you going to do to punish the illegal immigrant for using an SSN that isn't there? If you knew who they were in the first place, this wouldn't be happening. So, you don't know who they are or where they live.
That's the whole problem. If your force people underground, you CAN'T track them and it just makes the situation worse. Put your self in their shoes. If your last home sucked so badly, you would risk your life to go to another place where you're very existence is a crime, would you give a crap about their laws?
The whole reason to make illegals legal is because illegal's have no reason to follow the law. Following the law will get them kicked out. Give them a reason to follow the law by making them legal, then we can tax them and track them.
Or lets do what you want, put them all in jail where it costs us $80k/year to keep them. Really, it costs us more to jail them than to let them at least work and contribute.
All super caps are low voltage, no way around that; There will just be a bunch of them in serial. The other problem is the electric motors typically run at higher voltages because they're more efficient like that and the AC-DC converter works better at higher voltages for energy recapture.
Ironically, I was not long ago(past few years) reading an article about antioxidants. The article was talking about every sources, including blueberries, chocolate(high grade, not candy style), tomatoes, and coffee, to name a few.
They had a special section of coffee and it's health benefits and cancer *reducing* antioxidant properties and how moderate coffee drinkers lived longer on average/etc.
Personally, I will believe a non-corporate research article about antioxidants before I believe from fear mongering group about how some plant's beans are cancerous.
" The sun is a celestial object, and celestial objects are nothing if not predictable. Why bother with cameras at all?"
I've never heard of this and never thought of this, but holy crap.. "duh". You should've patented it. So much simpler than "tracking". All you would need is your long/lat info. Easily figured out with a cheap integrated GPS unit. Good thinking outside the box:-)
"That means that you can be picked out of a crowd of 2^18.8 people -- 456,419. With an estimated two billion people on the internet today"
Tack on your IP address and they can figure out which city you're connecting from. So, I can be identified out of a crowd of 456k people, but my city only has 10k people. Sounds like they probably keep track of me quite easily.
The recent Netflix data about average speed had my ISP above Comcast. If I tracert the data from Netflix, it's coming from Comcast. Somehow my ISP has a better connection to Comcast than Comcast's own customers. Go Figure.
Just a minor correction for your future posts. Intel and AMD don't create content, so it wouldn't be "copyright", but patent infringement. Copyright is for content, Patent for designs and TradeMarks for names.
Also, I think the settlement was because of Intel's anti-competitive business dealings. You know, like telling Dell they couldn't get certain Intel chips if Dell sold AMD CPUs., stuff like that.
He said that with current hardware "you have to write very close to the hardware to get any reasonable speed increase".
He's saying that you're better off just programming on your CPU than using OpenCL for the kind of stuff he was doing. OpenCL is a good idea, but in his case, if you can't get a performance benefit from it, why use it?
They're currently working on pre-emptive multitasking for GPUs right now.
ATI supports what they call "Anyc multitasking". Their hardware allows multiple kernels to run at the same time and the hardware abstracts everything out so each kernel thinks it's getting the whole GPU. The best part about this design is you can have long running kernels and very few context switches, so it should be more efficient. I guess this is currently useless because it must be supported by the OS/etc. Maybe DX12 will fix this and allow more than one type of "multitasking".
"Fusing" a high end GPU with a high end CPU would be a horrible idea. A large costly die and horrible graphics performance. You need dedicated video memory to have a fighting chance in the graphics arena. What you would get is a slower than high end graphics card coupled with a CPU that's weaker than it should be. There are limits on die sizes and pins.
Now, a special low latency connection between the CPU and the GPU would give the best of both worlds. A discrete GPU, but quick with crunching large data sets.
A smaller "GPU", primarily used as a co-processor, will always be beneficial because it adds enough vertex processing without eating up a crap ton of die space.
I think we'll see the weaker Fusion GPU being used for low latency vertex crunching and the discrete GPU being used for high throughput vertex crunching. Both having their own specialized use.
One side of me says "who cares, such a small percentage of LAN gamers" but the other side of me says "I grew up playing Warcraft/Warcraft2/Doom/Quake/Counter-strike/etc on LAN and it was the atmosphere of it all".
Why would Blizzard even want to use Steam? It would be annoying to have to log into Steam, only to then log into SC2/WoW/etc.
Because of NDAs, current rumors are Steam charges ~30% of the sale price. I don't think Blizzard would be willing to had over that kind of money when they already have the infrastructure.
A 3 degree difference is the difference between having the "North Pole" and having a large ocean. It is currently very probable for the entire Arctic to melt entirely by 2100 without the current surges of CO2 output.
Santa Claus will have no where to live, unless he plans to live on a boat at the "North Pole"
Actually, out of the box, I learned enough in my University that I could setup a network of Cisco routers, lock everything down with ACLs, properly organize the network with subnets and VPNs, setup either a Linux or Windows server, lock down either the Linux or Windows servers, lock down the server's firewalls, setup tripwire and snort to monitor the servers and the network, and setup databases, lock those down, setup apache or IIS, design my own scalable DB layout, and write my own web apps and SQL code in a secure way. Unfortunately, our Uni was Microsoft biased, so web devel was all ASP.Net.
Our teachers always emphasized on "learning to learn". Most of our 300 classes were either project or research based. We could use the internet or books/notes during our tests, but not our neighbors. Teachers said they didn't want us to memorize everything, but know how to look it up and get the correct idea.
Our capstone projects were always internships and the customer's rating was 40% of the grade, our peers 50% and our teacher 10%.
Over the past 20 years, the CIS major at my uni has had a 100% job rate in our field with in 6 months of graduation with an average starting wage of ~$70k. Pretty good for a $1600/sem state uni. and book rentals were free to... w00t!
I found a job in my field, with in 3 months of graduation, during this recession.
My experience with 2 year vocational was from my CIS degree. A large part of Computer Information Systems is Databases. We had 2 year tech college wanting to transfer their DB credits over to the university. Know what their DB knowledge was? Using Excel and Access. No SQL, no theory, they put indexes everywhere because they magically made things faster, and did everything via the GUI. Our college credits reflected MSSQL/Oracle/Math/Theory/Design/Optimizations.
Yes, they could quickly make a DB, which is great for immediate use, but they would make the most horrible large DB designs where speed and expandibility was a requirement.
I guess one could argue that college is important where the design is more important than the functionality. ie, a poor design and proper functionality is actually worse than non-functional because it can give a false sense of security. Like a poorly designed web site that allows SQL injection and someone exposes a bunch of SSNs/etc.
I wish more people knew this stuff. I think building new coal power plants should be outlawed and coal should be completely phased out before the end of the century. I don't care what else is built, anything but coal.
Linux needs user mode video drivers so if your video card crashes, it doesn't crash your windowing system or your computer.
The ability to use your IGP when processing is low and transparently switching to your dedicated GPU once it gets high enough would be nice to.
I know I won't be using Linux for my desktop until I get some multi-threaded 3D rendering support and drivers that don't crash the computer. I want to make use of my 3rd gen $300 graphics card. I get a new video card every 2-3 years, I don't want to wait 5 years to use it. It's not like I get the newest tech either, I wait for the 2nd-3rd gen of a tech so it's stabilized.

"Remember that the energy pumped out by a microwave is roughly 1000 times that of the peak output of a CDMA phone"
More than that. My CDMA phone peaks at 0.2watts and my microwave is ~1200watts(very typical). That's about 6,000 times stronger.

My anecdotal experience.
A hanging driver or non-responsive hardware is different than a crashing driver. If code crashes while in kernel mode, bad things happen.
