Official feedback on OpenGL 4.4 thread

  • Posted on March 30, 2017 at 5:20 pm

 SIGGRAPH – Anaheim, CA – The Khronos™ Group today announced the immediate release of the OpenGL® 4.4 specification,bringing the very latest graphics functionality to the most advanced and widely adopted cross-platform 2D and 3D graphics API (application programming interface). OpenGL 4.4 unlocks capabilities of today’s leading-edge graphics hardware while maintaining full backwards compatibility, enabling applications to incrementally use new features while portably accessing state-of-the-art graphics processing units (GPUs) across diverse operating systems and platforms. Also, OpenGL 4.4 defines new functionality to streamline the porting of applications and titles from other platforms and APIs. The full specification and reference materials are available for immediate download at http://www.opengl.org/registry.

In addition to the OpenGL 4.4 specification, the OpenGL ARB (Architecture Review Board) Working Group at Khronos has created the first set of formal OpenGL conformance tests since OpenGL 2.0. Khronos will offer certification of drivers from version 3.3, and full certification is mandatory for OpenGL 4.4 and onwards. This will help reduce differences between multiple vendors’ OpenGL drivers, resulting in enhanced portability for developers.

New functionality in the OpenGL 4.4 specification includes:

Buffer Placement Control (GL_ARB_buffer_storage)
Significantly enhances memory flexibility and efficiency through explicit control over the position of buffers in the graphics and system memory, together with cache behavior control – including the ability of the CPU to map a buffer for direct use by a GPU.

Efficient Asynchronous Queries
(GL_ARB_query_buffer_object)
Buffer objects can be the direct target of a query to avoid the CPU waiting for the result and stalling the graphics pipeline. This provides significantly boosted performance for applications that intend to subsequently use the results of queries on the GPU, such as dynamic quality reduction strategies based on performance metrics.

Shader Variable Layout (GL_ARB_enhanced_layouts)
Detailed control over placement of shader interface variables, including the ability to pack vectors efficiently with scalar types. Includes full control over variable layout inside uniform blocks and enables shaders to specify transform feedback variables and buffer layout.

Efficient Multiple Object Binding (GL_ARB_multi_bind)
New commands which enable an application to bind or unbind sets of objects with one API call instead of separate commands for each bind operation, amortizing the function call, name space lookup, and potential locking overhead. The core rendering loop of many graphics applications frequently bind different sets of textures, samplers, images, vertex buffers, and uniform buffers and so this can significantly reduce CPU overhead and improve performance.

Streamlined Porting of Direct3D applications

A number of core functions contribute to easier porting of applications and games written in Direct3D including GL_ARB_buffer_storage for buffer placement control, GL_ARB_vertex_type_10f_11f_11f_rev which creates a vertex data type that packs three components in a 32 bit value that provides a performance improvement for lower precision vertices and is a format used by Direct3D, and GL_ARB_texture_mirror_clamp_to_edge that provides a texture clamping mode also used by Direct3D.Extensions released alongside the OpenGL 4.4 specification include:

Bindless Texture Extension (GL_ARB_bindless_texture)
Shaders can now access an effectively unlimited number of texture and image resources directly by virtual addresses. This bindless texture approach avoids the application overhead due to explicitly binding a small window of accessible textures. Ray tracing and global illumination algorithms are faster and simpler with unfettered access to a virtual world’s entire texture set.

Sparse Texture Extension (GL_ARB_sparse_texture)
Enables handling of huge textures that are much larger than the GPUs physical memory by allowing an application to select which regions of the texture are resident for ‘mega-texture’ algorithms and very large data-set visualizations.

OpenGL BOF at SIGGRAPH, Anaheim, CA July 24th 2013
There is an OpenGL BOF “Birds of a Feather” Meeting on Wednesday July 24th at 7-8PM at the Hilton Anaheim, California Ballroom A & B, where attendees are invited to meet OpenGL implementers and developers and learn more about the new OpenGL 4.4 specification.

Features ‘Handwriting’ Simplify Use Google Translate

  • Posted on March 28, 2017 at 7:13 pm

CALIFORNIA – Google is taking the handwriting feature in Google Translate. This feature allows users to write their own posts with hard letters like Japanese, Chinese, and Arabic, and then translated by their gadgets by Google Translate.

Google reveals, this feature is provided for the traveler who currently travel to countries with languages ​​that do not use the letters of the alphabet or has complicated letters.

Can imagine if a British tourist who was a walk to China and see the street names with writing that is not understood. With handwriting input features of Google Translate, its just write or draw a silly row of letters on his smartphone or tablet, and then stay translate into the desired language.

“Handwriting feature allows you to translate phrases, even if you yourself did not know and did not know how to type the character,” said Google product manager, Xiangye Xiao, as reported by CNet.

For example, you see the writing in Chinese characters, but you do not know how to type in the text. With Handwriting feature, you just need to mimic the shape of the piece and then translate it, “she added.

Handwriting feature has been provided by Google in 45 kinds of language that are considered complicated character. Among them are Arabic, Chinese, Japanese, Laos, and Greece.

Gateway DX4870-UB2B

  • Posted on March 28, 2017 at 5:31 pm

The Gateway DX4870-UB2B ($499.99 list) is a basic tower desktop PC that checks all the boxes on what you need from a new desktop, particularly if you already have a LCD display that you’re carrying over. It’s speedy for its segment, has capacious storage, will let your family keep many documents open simultaneously, and it’s relatively inexpensive. Unlike the $300 bargain basement specials, the DX4870-UB2B$499.99 at Best Buy comes with a modern Intel Core i3 processor, dual-band Wi-Fi, and lots of drive space. It’s expandable, so it can grow with your family. It’s not ground breaking, but it’s a solid choice with a great bang for the buck, so it’s our latest Editors’ Choice for budget desktop PCs.

Design and Features
The DX4870-UB2B follows other Gateway desktops, looking almost identical to the last black tower Gateway DX4870-UB17$329.99 at Newegg.com ($500). Like that model, the DX4870-UB2B comes in a tower chassis with black panels all around, including the plastic front panel and metal side panels. The system’s tray-loading DVD burner is hidden, but two of the system’s USB 2.0 ports, SD card reader, and audio jacks are exposed on the top front of the chassis. In the back, the system has four more USB 2.0 ports, two USB 3.0 ports, PS/2 mouse and keyboard ports, HDMI, VGA, Ethernet, more audio jacks, and two connectors for the included WiFi antennas. It would have been nice if the front USB ports were USB 3.0 to accommodate USB hard drives instead of the slower USB 2.0.

The inside of the system is certainly expandable, with plenty of space to move around for future upgrades. The system has space for two additional drives: one optical 5.25-inch bay and one 3.5-inch hard drive bay. Theoretically, you could shoehorn another three to four 2.5-inch notebook class drives in the same space, provided you have the correct brackets to hold the drives. The motherboard has four free SATA ports to service these drives. The system also has two DIMM slots free, along with a slot for a PCIe 3.0 x16 graphics card and two additional PCIe 2.0 x1 expansion cards. One PCIe x1 slot is occupied by the included 802.11a/b/g/n Wi-Fi card, which will serve most users well. This is an improvement over other budget systems like the Lenovo IdeaCentre Q190$416.03 at antonline.com ($400) and Zotac Zbox ID83 Plus$448.99 at Amazon ($473), both of which don’t support 5Ghz WiFi, only the more common and crowded 2.4GHz channels.

The last consideration you have to make for expandability is the system’s 300W power supply. While sufficient for additional drives and minor expansion cards, 300W will be insufficient for a high-powered discrete graphics card with Nvidia’s or AMD’s highest end GPUs. You can of course swap out the included power supply, but most budget system buyers never open their chassis, even if they are tempted by the system’s expandability. Bring a screwdriver if you dare, because you’ll need it for the case door and the drive bays. At least the internal card slots are tool-less.

Like other Gateway systems, the DX4870-UB2B comes with quite a few pre-loaded applications and utilities. These include 7digital, Zinio, Kindle, eBay, Chacha, Netflix, NewsXpresso, Amazon, Tunein, Hulu Plus, Xbox Games, Cut The Rope, Stumbleupon, Skype, Merriam-Webster, Britannica, Spotify, Microsoft Office (ad), Norton Internet Security), and Wild Tangetn games. That’s a lot of pre-loaded apps, and most if not all are available for free from Microsoft Windows Store. While you may want to spend a few moments uninstalling all these programs, fret not, since the system has a capacious 1TB hard drive with plenty of free space left. The DX4870-UB2B comes with a standard one-year warranty.

Performance
The system comes with a third-generation Intel Core i3-3240 processor, 6GB of DDR3 memory, Intel HD Graphics 2500 (integrated in the Core i3 processor), and a 1TB 5,400rpm SATA hard drive. All of these components mean the system is plenty fast on our benchmark tests, certainly faster than the Lenovo Q190 and the Zbox ID83 Plus. That said, there are systems in this price range that are faster, notably the Polywell Nano i3-Q7 ($595) which trades physical and storage space for SSD speed, and the Acer Aspire AT3-600-UR11$449.99 at Newegg.com($600), which has a discrete graphics card and slightly more powerful processor adding to its performance totals. Check the performance chart link to see the final numbers, but suffice to say the DX4870-UB2B has the performance to keep your family happy for the next five years or so.

“The application is not only Internet-based, but also expanded and facilitated by the ability beraplikasi using 3G wireless communication technology, or the network and mobile devices (smartphones) are already widely used in parts of the country people,” he said after signing the MoU between NSDevil cooperation with PT Solar Core Communications.
The MoU was signed by CEO NSDevil Un Joo Lee, and Commissioner of PT Surya Inti Communications Honye Fauzia Aurelia.
Tonny said that in the era of the IT department, Indonesia would not want to immediately implement a system of effective and efficient education. “This new system is the development of E-Learning has begun to be applied. E-Learning is limited to the Internet network. U-Learning while utilizing communication network of the vendor, without stuck on a PC or laptop, “he said.
He explained that his company is considering cooperation with a number of educational institutions started elementary school, junior high, high school, and college. Education training centers, can also take advantage of this technology.
“This technology is also appreciated by the Ministry of Education and Culture, which was considered to help bring about equality of education in Indonesia,” he said.
Fauzia Honye Aurelia, Commissioner of PT Surya Inti Communications, adding the development in Indonesia since November 2012, has collaborated with the University NSDevil Pasundan Bandung, as a pilot project in penerapakan UBT and U-Learning.
“From the evaluation of the first phase in June 2013, he said, showed significant results for students and faculty who have tested penerapakannya in the lecture, to semester exams,” said Honye.

The Water Proofing

Sony Xperia Z’s lips at the Consumer Electronic Show (CES) 2013 in Las Vegas in early January. Because this phone has the security features that is waterproof.

U3-436-SonySmartphone dimensions 139 x 71 x 7.9 mm screen has 5 ˝. With such a wide screen, the display explores the experience is more freely, though it would be difficult to operate with one hand. Smartphone flat box shape does look pretty, it’s just feels less comfortable grip. This smartphone is also layered glass on each side. Those who would like smartphones bodied clean, need frequent cleaning traces of the hand attached to the glass. Dressings glass also makes it feel a little slippery when held.

The placement of the power button and the volume of the right middle, making it easy to reach buttons when holding, either left or right-handed. Micro-USB port, a micro-SIM, microSD, headset jack and has a special cover so that water does not enter into these holes.

Sony Xperia Z screen uses the Bravia Engine 2. 1080 × 1920 pixel image displays sharp colors. When used under strong light, the screen can still display a good image. This screen does not use IPS panels, so that the sharpness of the picture is only valid when it is in plain sight. Once tilted, the color looks a little foggy. The screen has wet finger tracking, so it can still operate even if your fingers wet. But, when in the water, he still does not respond to touch.

One more thing to note is hot. When using a smartphone intensive, especially when connected to the internet, so it feels very hot. Although the heat was tolerable hand, the heat is quite disturbing because the effect on Li-ion 2300mAh battery that is growing quickly depleted. This substantial battery can last all day with moderate internet usage. In addition, the Sony Xperia Z also has stamina mode that turns off the internet when the smartphone is not active. Internet will be active again after Sony Xperia Z used.

This smartphone’s camera using RS 13 megapixel Exmor sensor, the resulting image is quite good. Sony Xperia Z adds many exciting features, such as burst and HDR function. There are also picture effects such as panoramic images and a variety of filters to be creative with the pictures taken. One favorite is the sketch effect. The camera is also capable of recording HD quality video.

Audio business, Sony presents the expiration monaural speaker and stereo sound with headphones. The resulting sound is quite crisp innate headphones in ears, though not too special. While the default mono speakers generate sound quite comfortable to hear. In tests conducted PCplus, Sony Xperia Z can still operate despite being dipped into the water. Turn on the music, until a call. It’s just the sound of the speakers so there selantang usually after dyed. Wait three hours, the speakers back to normal.

Q&A: Microsoft Talks Changes to SkyDrive in Windows 8.1

  • Posted on March 21, 2017 at 4:49 am

When was the last time you had to delete a bunch of photos or apps on your mobile device to clear out space? With the massive amount of data generated every day, it’s easy to exhaust all the available storage on your phone or tablet.

And this problem is only getting worse. Industry trends suggest that device storage capacities are growing at 25 percent per year, but the amount of data being produced is increasing even faster — by around 50 percent a year, according to Microsoft. The software giant is looking to address this problem with SkyDrive, which will be updated in Windows 8.1 with the goal of giving you access to your files at all times, without taking up all your available storage or Internet bandwidth.

The updated service utilizes what Microsoft refers to as “placeholder files,” which look and feel like normal folders and files with one major change — you don’t download the full file until you access it. The placeholder file contains just a thumbnail image and some basic properties, making it significantly smaller than its actual size. This means that 100GB of files in SkyDrive will use up less than 5GB of storage on the hard drive of your Windows 8.1 device, Mona Akmal.

“I have a Pictures folder in SkyDrive that’s 5.6GB in size but it’s only taking up 185MB on the local disk,” Akmal wrote.

Another major change to SkyDrive in Windows 8.1 deals with offline access to files. With the SkyDrive app, you’ll now be able to mark any folders or files you want remain available when you lose Internet connectivity.

Any edits you make to a file while offline will automatically be synced back up to SkyDrive when you regain a connection. For added convenience, all the files you open or edit on your device will automatically be marked for offline access.

As a reminder, new SkyDrive users get 7GB of storage for free. After that, an additional 20GB costs $10 per year, while 50GB will set you back $25 a year, and 100GB costs $50 a year.

We sat down with Angus Logan, group product marketing manager for SkyDrive (pictured below), last week to get the scoop on the most important changes to the online storage service in Windows 8.1.
