Submission + - NVIDIA G-SYNC Display Technology Explored (

MojoKid writes: Back in September at a press event in Montreal, NVIDIA CEO Jen-Hsun Huang announced what he called “one of the most important works NVIDIA has done for computer graphics.” The technology, called G-SYNC, is an end-to-end graphics and display architecture that starts with a Kepler-based GPU and ends with a G-SYNC module within a monitor. The G-SYNC module is piece of hardware that replaces the scaler inside a monitor that essentially does away with the fixed vertical refresh rates of current displays. To put it simply, what G-SYNC does is keep a display and the output from a Kepler-based GPU in sync, regardless of frame rates or whether or not V-Sync is enabled. Instead of the monitor controlling the timing, and refreshing at say every 60Hz, with G-SYNC the timing control is transferred to the GPU. NVIDIA achieved this by developing the G-SYNC module, which will be featured in a number of new monitors starting next year. The G-SYNC module replaces the scaler and controller boards in current displays and allows for the dynamic refresh rates mentioned earlier. The module is comprised of an FPGA—programmed by NVIDIA—a bit of DRAM, and a DisplayPort input. At this time, G-SYNC requires a Kepler-based GPU, with a DP output, and obviously a G-SYNC enabled display. To fully appreciate the technology, a high-DPI gaming mouse is also recommended.

Not exactly 12 times. 5 TWh is for the month of July which is probably one of the peak months in the year. You can see in the linked PDF the graph for monthly production. Mininal production was 0.35 TWh in January. I don't know how much of an impact is the growing number of solar panels and how much is the seasonal effect. We can have a better look when we get the data for the rest of the year.

When you picked your plan/phone you were not free, just a consumer.

How was I not free? Did someone force me to buy the plan I have (or even to buy one at all)?

And if you were in the US (or worse, Canada), _all_ your options were overpriced and crappy.

I am in Canada, and I think the plan I got fits my needs perfectly so I don't think it's overpriced or crappy, otherwise I wouldn't have bought it. You might think differently, but that's because we don't have the same needs.

Why? what is wrong with voting?

What is wrong with voting is that you can't make your own choices, you have to go with the majority.

we all use/need the collective services in the same way.

No we don't all need the same services in the same way.

If it makes you happy, think of voting as a market operation. But remember: it is not freedom to individually decide on a globally suboptimal solution that we then all need to collectively live with. It is stupidity.

You might argue that it is stupid or not optimal (I would disagree with that), but it certainly is freedom to individually decide.

And BTW, yes, people can decide for you. They do, all the time: doctors decide what you have, engineers decide on your car's design, coders on how your programs are made, cell phones companies on their pricing schemes, the shop owner on the products that are on his shelves, the traffic authority the circulation plan of your neighbourhood, other countries the rules for access to their territories, the central banks decide on the value of your bank account, designers decide on the look of your garments.

But they don't decide which car I buy, which programs I use, what cell phone scheme I buy or if I even buy one of those. Imagine if we had to vote on what cell phone plans we wanted and then everyone would get what the majority decided. What if I didn't want a cellphone, or I wanted a cheaper plan or a more expensive one? I would have no choice but to accept what the majority decided for me. Even worse, we rarely vote on direct issues like that. We only vote for who is going to decide for us, leaving us with even less choice on how to run our own lives.

Also, what is "waste"? is funding fundamental science waste? is funding liberal arts waste? are the likes of the FDA waste? is paying for some dubious piece of art in your own town waste? is paying people to check for fraud waste, or is the fraud the largest cause of waste?

In the marketplace, we can all decide individually what we consider waste and what we don't. Nobody can decide for us. That is called freedom (also capitalism).


Another Step Towards the Driverless Car 224

jtogel writes "At Essex, we have for some time been working on automatically learning how to race cars in simulation. It turns out that a combination of evolutionary algorithms and neural networks can learn how to beat all humans in racing games, and also come up with some quite interesting, novel behaviours, which might one day make their way into commercial racing games. While this is simulation, the race is now on for the real thing — we are setting up a competition for AI developers, where the goal is to win a race between model cars on real tracks. As the cars will be around half a meter long, the cost of participating will be a fraction of that for the famous DARPA Grand Challenge, whereas the challenges will be similar in terms of computer vision and AI."

Surprise, Windows Listed as Most Secure OS 499

david_g17 writes "According to a Symantec study reported by Information Week, Microsoft has the most secure operating system amongst its commercial competitors. The report only covered the last 6 months of vulnerabilities and patch releases, but the results place Microsoft operating systems above Mac OS X and Red Hat. According to the article, 'The report found that Microsoft Windows had the fewest number of patches and the shortest average patch development time of the five operating systems it monitored in the last six months of 2006.' The article continues to mention the metrics used in the study (quantity and severity of vulnerabilities as well as the amount of time one must wait for the patch to be released)."

Journal Journal: Greenies: Why ethanol instead of methanol? 14

If this has been written or posed elsewhere, please let me know? It just dawned on me the other day.

Why is ethanol supposed to be so great when racers have been using methanol for a long time? Plenty of methanol data and experience out there, but ethanol had to be dragged into a market with a bunch of government "help".

Submission + - Self Booting Games?

pentalive writes: Most games available now require you to leave the CD in the CD-ROM drive, Most machines available today can boot from CD-ROM? Why doesn't anyone market games that boot directly from their CD-ROM (using something like Ubuntu behind the scenes as the OS). I don't play FPS or MMORG (I play roller coaster tycoon mainly), you who do, do you play Diablo and also edit "that report" in word at the same time? Doom and Excel? Put the CD in and reboot the machine to play the game, Who cares what OS it runs when it's "working". What do you think? good idea?
