HTC One unveiled: 4.7-inch 1080p display, 1.7GHz quad-core Snapdragon 600, UltraPixel camera, Android 4.1.2 with Sense 5

Despite the abundant fanfare and critical acclaim, HTC’s One X just couldn’t quite mark the spot in 2012. No wonder, then, that the company’s lopped off that extraneous letter in favor of a fresher start and renewed brand focus for its latest flagship: the One . Gone by the wayside are those pure polycarbonate hulls — HTC’s Sense 5 -laden Android Jelly Bean (4.1.2) handset comes crafted with an all-around premium look and feel, housing its 4.7-inch 1080p Super LCD 3 display (boasting 468 dpi and protected by Gorilla Glass 2) in a machined aluminum unibody. And, in a bid for the top spot on the mobile totem pole, the One also bears the distinction of being ( one of ) the first smartphones to feature Qualcomm’s quad-core Snapdragon 600 , clocked here at 1.7GHz and paired with 2GB RAM.

NVIDIA unveils the GTX Titan, an enormous graphics card that costs $1,000 (eyes-on)

NVIDIA’s GTX Titan is rumor no more , as the American computer hardware company unveiled the superpowerful graphics card this morning. With 2,688 CUDA cores, 6GB of GDDR5 RAM, and 7.1 billion transistors packed into the 10.5-inch frame, Titan’s capable of pushing 4,500 Gigaflops of raw power — NVIDIA’s pitching Titan as the means to “power the world’s first gaming supercomputers.” The company even showed off the Titan in its mightiest form, bootstrapped to two others running together (three-way SLI), which powers graphics showcase Crysis 3 running at its highest settings: a whopping 5760×1080 resolution across three monitors. Of course, a setup like that would cost you quite a pretty penny; just one GTX Titan costs $1,000, not to mention three (nor all the other hardware required to support it). Should you prefer your gaming PCs to not be of the neon-lit, triple GPU, above-$10,000 variety, NVIDIA was also showing off the Titan in a Falcon Northwest boutique PC. The company’s working with a variety of boutique PC makers to incorporate the Titan (see: Maingear ), making NVIDIA’s top of the line a teensy bit more accessible to your average joe. GTX Titan is the new top of the line for NVIDIA, effectively pushing aside the GTX 690 and setting a new benchmark for performance. Of course, with a $1,000 price tag and freedom — nay, encouragement — to tweak its nitty gritty settings, the Titan isn’t really meant for your average anyone. The PC game-playing early adopters, however? Here’s your next GPU. Hopefully you’ve got a big, empty space in your rig, as you’ll need it. The GTX Titan arrives on February 25th for $999.

Clever Students Use Game Theory to Get Perfect Scores on an Exam

Dr. Peter Fröhlich of Johns Hopkins University grades exams so that the highest scoring exam receives a 100% grade and all others fall below on a curve. It wasn’t a Kobayashi Maru scenario , but his exams are hard. Fröhlich’s students devised a cunning plan to all get A grades. It involved boycotting the exam: Since he started teaching at Johns Hopkins University in 2005, Professor Peter Fröhlich has maintained a grading curve in which each class’s highest grade on the final counts as an A, with all other scores adjusted accordingly. So if a midterm is worth 40 points, and the highest actual score is 36 points, “that person gets 100 percent and everybody else gets a percentage relative to it,” said Fröhlich. This approach, Fröhlich said, is the “most predictable and consistent way” of comparing students’ work to their peers’, and it worked well. At least it did until the end of the fall term at Hopkins, that is. As the semester ended in December, students in Fröhlich’s “Intermediate Programming”, “Computer System Fundamentals,” and “Introduction to Programming for Scientists and Engineers” classes decided to test the limits of the policy, and collectively planned to boycott the final. Because they all did, a zero was the highest score in each of the three classes, which, by the rules of Fröhlich’s curve, meant every student received an A. Dr. Fröhlich abided by his grading policy and gave all students A grades, as well as congratulating them on their cooperative spirit: Fröhlich took a surprisingly philosophical view of his students’ machinations, crediting their collaborative spirit. “The students learned that by coming together, they can achieve something that individually they could never have done,” he said via e-mail. “At a school that is known (perhaps unjustly) for competitiveness I didn’t expect that reaching such an agreement was possible.
