Facebook top-menu not scrolling problem in Chrome Fix

Hello again to this new fast tutorial, got this weird problem for one week and thought that clearing the cache will fix the problem, but no this is a chrome related bug, when you scroll down on your news feed the Facebook top-bar menu will stay fixed and don't float along with the page, and this will be a pain in the head when you try to check for messages for example.

So the problem is in Chrome browser not fully compatible with the new Facebook layout, and the solution is very simple.

  • First thing to keep things clean, clear the cache except passwords.
  • Then the fix is to zoom the page in or out (Ctl + mouse scroll) and test if the Facebook menu keep floating, on my case the menu stop scrolling when the zoom between 100% and 150%.

So until this bug is fixed use this trick.

Realistic fire flame physics demonstration from Nvidia details

Another Gamework demonstration video from Nvidia, this time it's a realistic flame blow physics demo showed on GTC 2014 using a GTX 780 Ti GPU at high pixels resolution.
NVIDIA FlameWorks is a system for generating cinematic fire, smoke and explosion effects for games. It combines a state-of-the art grid-based fluid simulator with an efficient volume rendering

The simulator uses a highly optimized solver which enables the simulation of high resolution grids in real-time. It supports collisions with standard primitives and includes a combustion
model for generating flame effects. The system is highly customizable and supports user defined emitters,forcefields and collision objects.
The GTC 2014 fire demo demonstrates the cinematic quality of fire/smoke together with ray marched reflections on the ground as well as interaction with a sphere. The demo uses a 512x256x256 voxel grid, meaning that 32M voxels are updated every frame and runs at more than 30fps on a GeForce 780TI.

For actual game use cases the voxel grid size is scalable and can be used with lower resolutions as well.
No Particles were used in the making of the demo.

Samsung 850 Pro Vs 840 Pro SSD Benchmark tests with new 3D V-NAND design

One of the most important key performance on today's computers is the storage device, SSDs becoming more and more important due to their high performance compared to regular HDDs, well today we're going to show you different tests results from our neighborhood of the new Samsung's release, the Samsung 850 Pro SSD.

After the successful 840 Pro SSD, here is the big company outs the 850 series with new features such as the Samsung's 3D V-NAND (vertical NAND) which consists using less space higher process unit resulting in higher capacities and better performance and power consumption.

Moving to the price, the 128GB version will costs $130, while the flag-ship is the 1TB version and will costs $730, all with 10 years limited warranty.

iPhone 6 5.5" Vs iPhone 6 4.7" Vs iPhone 5s size comparison video

Another cool video to share about the next iPhone 6 from "TechSmartt", this time it's a size comparison between the 5.5" display, 4.7" version of the iPhone 6 and an iPhone 5S.

The 5.5" version is too big and it look like a Fablet than a smartphone, while the 4.7" version looks good for most users, check out this nice comparison of two early case's models with the exact design of the iPhone 6.

Some consider the Intel's next generation or series of processor are far from release or even thinking about, here are the first information about the next generation Intel Core 5000 series CPUs with a leaked table showing specification of the intel Core i7-5960X, Core i7-5930X and the Core i7-59120X, these products expected to be available on Q3 2014.

These high-end processors are Haswell-E  LGA 2011-3 based, they will features higher specifications than their precedent edition and for the first time for desktop CPU here is the appearance of DDR4 controller on these three CPU clocked at 2133Mhz and can do up to up to Quad Channels memory configuration.

The flag-ship Core i7-5960X will have 20MB of cache a base clock @ 3.0Ghz and a price tag at 1000$, the Core i7-5930X and the Core i7-59120X will get a new cores configuration with only six physical cores instead of eight, this will have a good impact on final price, beside that, intel will recompense the slashed core by increasing the base clock speed up to 3.5Ghz, all processors will have 140W of TDP, the price for the Core i7-5930X will be close to 550$ and for Core i7-59120X, it won't pass 350$ at first launch, check out the table bellow for more details.
