Bitcoin Mining Tests On 16 NVIDIA and AMD GPUs 403

Vigile writes "For users that have known about the process of bitcoin mining the obvious tool for the job has been the GPU. Miners have been buying up graphics cards during sales across the web but which GPUs offer the most dollar efficient, power efficient and quickest payoff for the bitcoin currency? A series of tests over at PC Perspective goes through 16 different GPU configurations including older high-end cards through modern low-cost options and even a $1700+ collection with multiple dual-GPU cards installed. The article gives details on how the mining programs work, why GPUs are faster than CPUs inherently and why AMD seems to be so much faster than NVIDIA."

Comment Re:Google+ tracking cookie (Score 1) 312

My best guess is that it identifies you for purposes of the +1 button, which is similar to Facebook's Like button. If you press it, that web page shows up on your G+ profile on the +1 tab. But even if you never press it, it still tells Google that you visited that web page.

Web pages like it because they get to be recommended on social networks. And the social networks like it because they can track your browsing habits. It's win/win!

Programming

Old-School Coding Techniques You May Not Miss 731

CWmike writes "Despite its complexity, the software development process has gotten better over the years. 'Mature' programmers remember manual intervention and hand-tuning. Today's dev tools automatically perform complex functions that once had to be written explicitly. And most developers are glad of it. Yet, young whippersnappers may not even be aware that we old fogies had to do these things manually. Esther Schindler asked several longtime developers for their top old-school programming headaches and added many of her own to boot. Working with punch cards? Hungarian notation?"

Confusion Reigns As Analog TV Begins Shutdown 434

As TV stations across the country switch off their analog signals, uncertainty reigns. Some 691 stations will have converted to digital broadcasting by midnight tonight (some interpreted the mandate as going digital by Feb. 17, not during Feb. 17, and shut down yesterday). This represents about a third of TV broadcasters nationwide. No one can say how many of the estimated 5.8 million households unready for the transition are in areas served by the stations that are switching now. The FCC added to the uncertainty by imposing extra conditions, making it unclear until last Friday exactly which stations would be switching at the beginning of the transition period. The article quotes a former analyst at Barclays Capital who said the whole process has been "botched politically."

Exchange Comes To Linux As OpenChange 249

joesmart writes to tell us that new work on OpenChange and KDE seeks to bridge the gap between groupware compatibility and open source. KDE developer Brad Hards spoke at the Linux.conf.au conference and said the goal of OpenChange is to implement the Microsoft Exchange protocols as they are used by Outlook. "OpenChange has client and server-side libraries for Exchange integration and relies heavily on code developed for Samba 4. It is open source software licensed under the GPL version 3. Hards said more work is being done on the client side and 'we have code for the server,' but estimates another 12 months of development is required to produce an OpenChange server ready for production."

New Ads That Watch You 238

Pandanapper writes to tell us Yahoo is reporting that if you find yourself watching an ad on a video screen in a public venue, the ad may be watching you as well. "Small cameras can now be embedded in the screen or hidden around it, tracking who looks at the screen and for how long. The makers of the tracking systems say the software can determine the viewer's gender, approximate age range and, in some cases, ethnicity -- and can change the ads accordingly. That could mean razor ads for men, cosmetics ads for women and video-game ads for teens."
