Tin đồn điện thoại Facebook ra mắt tuần này


Tin đồn điện thoại Facebook ra mắt tuần này

Dù chính Mark Zuckerberg từng tuyên bố họ không có kế hoạch tự phát triển smartphone riêng, thông tin điện thoại mang thương hiệu Facebook sẽ trình làng ngày 15/1 vẫn tiếp tục được lan truyền.
  • 15/1 là ngày Facebook tổ chức một sự kiện đặc biệt tại trụ sở của họ nhưng trong thư mời báo chí lại không tiết lộ sẽ thông báo điều gì

Một ý tưởng điện thoại Facebok với phím Home hình chữ F.
Chuyên gia MG Siegler của TechCrunch cho hay: "Rất nhiều nguồn tin nói với chúng tôi rẳng một điện thoại Facebook sẽ được trưng bày vào 15/1. Hiện vẫn chưa rõ đó là sản phẩm phần cứng do chính họ phát triển (giống thiết bị của Apple và Amazon) hay đơn giản chỉ là họ sử dụng phần cứng từ một nhà sản xuất khác (như Nexus của Google) để trình diễn cái gọi là hệ điều hành Facebook OS cho di động. Nhưng có khả năng đó sẽ là điện thoại Facebook hơn là Facebook OS chạy trên một chiếc điện thoại của hãng khác".
Tuy nhiên, bản thân CEO Mark Zuckerberg từng tuyên bố trong chính hội thảo củaTechCrunch hồi tháng 9/2012 là: "Nhiều người nói chúng tôi đang phát triển điện thoại. Nhưng đó rõ ràng là chiến lược sai lầm đối với chúng tôi".
Theo Siegler, Facebook cũng khẳng định với những đối tác lớn của họ là Google và Apple rằng họ không có ý định cho ra mắt điện thoại. Do đó, nếu thực sự có điện thoại Facebook tuần này thì rõ ràng những người đứng đầu mạng xã hội lớn nhất thế giới đã thay đổi suy nghĩ, hoặc đó chỉ là smartphone giá rẻ dành cho thị trường mới nổi, không cạnh tranh trực tiếp với đối tác.

LAS VEGAS--Looking for a one-of-a-kind storage device? LaCie has one for you.
The storage vendor unveiled today at CES 2013 a new USB 3.0 external hard drive, called the Blade Runner, that either screams crazy, or shows off as a statement piece, depending on your mood. LaCie says the drive is designed to look more like a piece of art than a storage device. And it indeed doesn't look like any external drives I've seen before.
The Blade Runner comes in a super-rugged all-aluminum body that is squared but not smooth. The body is designed to look like multiple thin blades cutting through a large potato in the middle. At first glance, the drive somewhat resembles a part of a car radiator. Looking closer, nobody can tell what it looks like. And that is the point.
LaCie says the Blade Runner makes a bold statement when having it on the desk. Only 9,999 units of the drive are made.

The artsy aspect aside, the drive's body also works as a heat-sink to keep itself cool. The drive is relatively light for how big it is and considering all the metal used in the making of it. On the inside, the Blade Runner houses a 4TB high-speed hard drive. On the bottom it comes with one USB 3.0 port and a power connector.
LaCie says each unit of the Blade Runner is custom-built to "ensure superb form and function." The drive comes with 10GB of free Wuala online storage and is available soon after CES 2013 for $330.

CES 2013: Nvidia Announces Project Shield And Tegra 4


CES 2013: Nvidia Announces Project Shield And Tegra 4

 by  - source: Tom's Hardware US

We're about to head out to the 2013 International Consumer Electronics Show. But before we leave, we wanted to take a moment to publish our thoughts about Nvidia's press conference, as its webcast happens. Tune in for our team's commentary.
8:24: Here we go!
8:29: Jen-Hsun Huang comparing PC gaming and console gaming. PCs give us more flexibility to increase quality versus consoles. Yup, we know. That's why we love PC gaming!
8:33: Introducing GeForce Experience. Didn't we hear about this back when the GeForce GTX 690 launched? Nvidia will pick the best settings for your game based on your configuration.
8:37: Great-looking demo, if you didn't know how to change your settings previously.
Before...Before......after GFE...after GFE
8:41: Onto a discussion of the relationship between 3D graphics and cloud computing. Wonder what's coming?
8:44: Introducing the Nvidia Grid, a server designed for computer graphics, "packed full of GPUs." One rack = 20 servers, 240 GPUs, 200 TFLOPS of computer performance (or about 700 Xbox 360s).
8:47: Andrew Fear loading up Trine 2 on an LG TV over the cloud. Grid receiver client was ported to the TV by LG. You plug in Ethernet to the television and you're able to access the game library online.
8:49: Now they're up and running on an Android-based tablet. Same thing; you fire up the client and go. Andrew starts right where he left off on the TV (same save state).
8:54: Still waiting for the big announcement. Tegra 2. Tegra 3...
8:57: Tegra 4. Four ARM Cortex-A15 cores, 72 GPU cores, Nvidia's first 4G LTE modem processor. This is still a 4-PLUS-1 design.
8:58: Demo time. Nexus 10 versus a Tegra 4-based prototype; 50 seconds on the Nexus, and 27 on the Tegra 4-based tablet to load 25 webpages.
9:05: High dynamic range imaging demonstration. Tegra 4 is going to allow two shots to be taken back-to-back. The cores then work in parallel to create the HDR image without the delay typically associated with taking pictures with HDR turned on.
9:18: On to video games. Dead Trigger 2. Interesting, but not necessarily mind-blowing. Chris Angelini: "That's still not the big announcement, by the way."
9:23: Software-defined radio introduction. Remember seeing the 4G LTE on Tegra 4? i500 Soft Modem from the engineers Nvidia acquired from Icera. 1.2 sustained trillion operations per second across eight programmable processors. Able to re-use the programmable logic for each stage of the pipeline, eliminating the need for fixed-function hardware. So, it's smaller. We're wondering how that's going to affect battery life, though. The benefit of fixed-function circuitry is often a reduction in power consumption; how will the programmable cores change this?
9:29: Chris Angelini: "Here it comes..."
9:32: Nvidia handheld, Project Shield. Project Thor is, er, something else ;-)
Tegra 4-powered (look at that huge heat sink), 38 Wh of batteries for between five and 10 hours of gameplay, according to Jen-Hsun. Apparently, 24 hours of high-def video playback. Bass-reflex audio system through tuned port. Better audio than an HP laptop with Beats. Console-oriented game controls. Runs Android. HDMI output, micro-USB, microSD slot, 3.5mm audio output. Top cover can be customized.
What about that display? Tell us more!
Touch-based control. Looks like Nvidia's alternative to a tablet, better-oriented to gaming.
9:45: Jen-Hsun continues demoing the Shield. 4K video playback over HDMI to a TV. Then, driving a 4K display in a 3D application from Shield (assuming that's scaled from 720p?). Multi-player capable over the network.
9:59: After some (many) technical difficulties, Jason and Jen-Hsun have a demo running of Need for Speedstreaming from a PC (Chris: "Hey, nice Tiki"), using GeForce Experience, to the Shield. We're looking forward to getting a feel for the control lag incurred by this.
10:04: It looks easy to connect to your Steam-based games through Shield and play through your (presumably) high-end PC. Nice to be able to work around the limitations of an ARM-based device to enjoy PC games on a handheld.
What's happening here is that the PC's hardware is responsible for rendering the 3D content, which is then sent to the Shield. What will the network bandwidth requirements be for this? Will gamers be interested in using a controller for titles they're used to playing with a keyboard and mouse? How do the graphics look on the streamed content?
We'll be answering all of this and more sooner than you think. Stay tuned to Tom's Hardware for more CES 2013 coverage than you've ever seen us do!

Fujifilm's X100s and X20 will launch in late March at $1299.95 and $599.95 (update: hands-on photos)


By Nathan Ingraham on January 7, 2013 03:37 pm



We're live at Fujifilm's CES 2013 press conference, and the company just announced pricing and availability for its X100s and X20 rangefinder-style cameras. The X100s will cost $1299.95 while the X20 will cost $599.95, and both will be available at the end of March. As we learned the other day, the X100s has been updated with a new 16.3 megapixel APS-C X-Trans CMOS II sensor, as well as a faster processor, the EXR II. Fujifilm promises the sensor will allow for autofocus of .08 seconds, and that with the processor, it will produce dramatically better resolution and noise reduction. The X20, meanwhile, offers a 12 megapixel 2/3-inch X-Trans CMOS II sensor and the same processor as the X100S. The X100s features the same 23mm f/2 lens that its predecessor included, while the X20 features an f/2.0 - f/2.8 manual barrel zoom lens. We're looking to try the cameras our for ourselves and will have impressions soon!

Update: We just got a chance to handle Fujifilm's brand-new X100s and X20 cameras — they feel much like their predecessors, but come with all-new internals. The cameras feel unsurprisingly solid and well-built, like all of Fuji's previous X-series cameras. The real differences will reveal themselves over more extended usage, but at first glance they certainly keep up the high hardware and build quality standards of the X-series.



























Update 2: A Fujifilm executive just showed us how the new "digital split image" display on the X100s rear viewfinder works — it looks like a major improvement over the standard process for manual focus when you're using an LCD viewfinder. Check it out below.
