I read the Meltdown paper so you don't have to

Meltdown is a cache-timing attack on Intel CPUs that allows all memory to be read by any process because of how they do Speculative Execution. If that sounds like a handful, we wrote this blog for you!

This post includes everything you must know before you can understand Meltdown as a developer (we assume no knowledge of CPU internals).

3D-Tech News Around The Web / meshoptimizer: Mesh optimization library
« on: January 12, 2018, 03:21:05 PM »
meshoptimizer is a mesh optimization library that makes indexed meshes more GPU-friendly.

Quote
When GPU renders triangle meshes, various stages of the GPU pipeline have to process vertex and index data. The efficiency of these stages depends on the data you feed to them; this library provides algorithms to help optimize meshes for these stages, as well as algorithms to reduce the mesh complexity and storage overhead.

The library provides a C and C++ interface for all algorithms; you can use it from C/C++ or from other languages via FFI (such as P/Invoke).

NVIDIA Supersizes PC Gaming with New Breed of Big Format Gaming Displays

PC gaming today makes the leap to a giant screen, with NVIDIA’s introduction of big format gaming displays, or BFGDs™.

Created in conjunction with NVIDIA hardware partners Acer, ASUS and HP, BFGDs integrate a high-end 65-inch, 4K 120Hz HDR display with NVIDIA® G-SYNC® technology together with NVIDIA SHIELD™, the world’s most advanced streaming device. The combination delivers a buttery-smooth gaming experience and your favorite media streaming applications — all on a giant screen.

“PC gamers expect high performance and instant response times, but, until now, they’ve been largely limited to traditional desktop displays,” said Matt Wuebbling, head of GeForce marketing at NVIDIA. “BFGDs change that. With NVIDIA’s latest technology built into these new displays, PC gamers can now experience their favorite titles in all the low-latency glory they deserve.”

At BFGD’s Heart: G-SYNC HDR
At the heart of BFGDs is the latest G-SYNC HDR technology that synchronizes the display’s 120Hz refresh rate to that of the game at every moment in time. This G-SYNC Variable Refresh Rate technology delivers a highly responsive, smooth, tear-free, immersive gaming experience unmatched by any display of this size.

Additionally, the 4K HDR display features a full-array direct backlight, 1,000-nit peak luminance and DCI-P3 color gamut for the ultimate in visual quality.

Ultra-Low Latency Gaming
Nothing is more important to gamers than responsive gameplay. G-SYNC technology brings the ultra-low latency found in G-SYNC desktop gaming monitors to the BFGD when gaming directly on the PC, Android™, another console or using NVIDIA GameStream™ technology from a desktop or laptop gaming PC.

Big Screen Streaming
The integration of the Android TV™-based SHIELD into BFGDs allows gamers to easily switch between gaming and other forms of entertainment. The bundled SHIELD remote and game controller allow for easy navigation and access to all of the world’s biggest streaming apps, including Netflix, Amazon Video, YouTube™ and Hulu.

With support for the Google Assistant, the entire experience can be controlled simply by using your voice. G-SYNC HDR technology also supports video playback at native framerates, including popular 23.976, 24 and 25 FPS formats. This matches the screen’s refresh rate to the video source’s actual frame rate, eliminating interpolation and presenting the video content as it was intended to be viewed by the director.

Availability and Pricing
BFGDs are available for hands-on demos at CES at the NVIDIA gaming suite and ASUS ROG showcase room at the Wynn Las Vegas by appointment only, and in the HP booth at the Pepcom and Showstoppers press events on Monday and Tuesday evening, respectively. General availability is expected this summer when pricing and further specifications will be announced.

Snelly is a system for physically-based SDF (signed distance field) pathtracing in a web browser.

Quote
A Snelly scene consists of 3d objects defined by a mathematical signed distance function (SDF) written in GLSL code. The SDF gives the distance to the surface from any given point in space, where the distance is positive in the exterior of the shape and negative in the interior (and of course zero on the surface). In each scene there can (currently) only exist three such specified objects, with different rendered material properties: a Metal, a Dielectric, and a general purpose plastic-like Surface ("uber" material). These three materials can freely intersect and embed one another.

It is generally quite challenging to find SDF functions which correspond to interesting shapes. We provide some example scenes (and this library of sample scenes will be added to over time). A lot of interesting examples and resources can be found on the web, at for example shadertoy. Fractal surfaces in particular are quite easy to define as SDFs, as described for example here.

3D-Tech News Around The Web / Reverse Z Cheat Sheet
« on: January 03, 2018, 07:53:08 PM »
Quote
Just recently I’ve started looking into ways to optimize the depth buffer precision for large draw distances and one specific approach caught my eye again. A technique which is now commonly referred to as Reverse Z. While it comes with just a few minor changes, the results can be quite considerable.

That considerable everyone should just go ahead and use it.

The general idea itself is actually very simple: instead of mapping the interval between the near and far plane [zn,zf] to [0,1], a special projection matrix is constructed in a way that it is being mapped to [1,0] instead.

Why this actually increases the depth buffer precision is not directly obvious, but I will also not go into detail here. I’ve added some references to articles on this topic at the end of this post.

Irvine, CA – December 7, 2017 – Toshiba Electronic Devices & Storage Corporation today announced the launch of the MG07ACA Series, the world’s first1 enterprise 14TB2 Conventional Magnetic Recording (CMR) HDD. Using a 9-disk, helium-sealed design, the new MG07ACA Series provides the power-efficient capacity and storage density needed by cloud-scale and enterprise storage solution providers to achieve their TCO objectives.

“We have raised the bar with the new MG07ACA Series 9-disk helium-sealed design,” said Akitoshi Iwata, Vice President of Storage Products Division, Toshiba Electronic Devices and Storage Corporation. “By utilizing an innovative design, we continue to improve the benefits that high-capacity disk storage can deliver to our broad global customer base.”

The MG07ACA Series features both 14TB 9-disk and 12TB 8-disk models. The helium-sealed 3.5-inch3 mechanical design realizes better storage density and a lower HDD operating power profile than the previous MG06ACA Series for optimal TCO in cloud-scale infrastructures. The series also utilizes Toshiba Group’s laser welding technology to ensure the helium remains securely sealed inside the drive enclosure. The drives support a SATA 6Gbit/s interface and 7,200rpm access performance. The 9-disk 14TB models achieve a 40% increase in maximum capacity over previous MG06ACA 10TB models. Additionally, the 14TB models improve power efficiency by over 50% (W/GB)4.

“Toshiba’s first helium-sealed nearline drive intercepts the market at a class-leading 14 TB capacity with CMR,” said John Chen, industry analyst at Trend Focus. “Its early time-to-market for this capacity positions the company well to meet the storage needs of large hyperscale and cloud companies. Additionally, the company’s choice of a 9-disk platform paves the way to achieving higher capacities in future product generations.”

“While enterprise server and storage customers realize that shingled magnetic recording (SMR) technology can improve HDD capacity, the adoption of SMR HDD products into server and storage systems is a transition that will take several years,” said John Rydning, Research Vice President for hard disk drives at IDC. “Toshiba’s new helium-sealed enterprise HDD is the world’s first 14TB of storage capacity using conventional rather than shingled magnetic recording technology, giving enterprise customers the highest capacity HDD available in the market today for existing server and storage system architectures.”

Sad news, everyone.

After months of deliberation, I have decided to stop the development of Classic Shell.

It was a great adventure for me that lasted 8 fun and exciting years. It started back in 2009 as a simple weekend project and over time grew to be a hugely popular software brand with many millions of downloads. It was in large part due to all of you, the active Classic Shell community, that reported issues, suggested features, provided translations, developed new skins and participated in forum discussions. My thanks go to you for your continued support and encouragement.

And of course, special thanks to Gaurav Kale, who stuck with me from the early days to the end. His passion for all things Windows was instrumental to the Classic Shell success.

There were few factors that led to my decision:
1) Lack of free time. I have other hobbies that demand my time, some related to software and some not. It requires a lot of effort to add new major features to Classic Shell and keep it relevant. Even keeping it running on newer version of Windows is a lot of work. That leads me to point #2

2) Windows 10 is being updated way too frequently (twice a year) and each new version changes something that breaks Classic Shell. And

3) Each new version of Windows moves further away from the classic Win32 programming model, which allowed room for a lot of tinkering. The new ways things are done make it very difficult to achieve the same customizations

So just how are people rated? Individuals on Sesame Credit are measured by a score ranging between 350 and 950 points. Alibaba does not divulge the "complex algorithm" it uses to calculate the number but they do reveal the five factors taken into account. The first is credit history. For example, does the citizen pay their electricity or phone bill on time? Next is fulfilment capacity, which it defines in its guidelines as "a user's ability to fulfil his/her contract obligations". The third factor is personal characteristics, verifying personal information such as someone's mobile phone number and address. But the fourth category, behaviour and preference, is where it gets interesting.

Under this system, something as innocuous as a person's shopping habits become a measure of character. Alibaba admits it judges people by the types of products they buy. "Someone who plays video games for ten hours a day, for example, would be considered an idle person," says Li Yingyun, Sesame's Technology Director. "Someone who frequently buys diapers would be considered as probably a parent, who on balance is more likely to have a sense of responsibility." So the system not only investigates behaviour - it shapes it. It "nudges" citizens away from purchases and behaviours the government does not like.
