Intel CPU list of bugs

Intel has a long history related to microprocessor bugs.


It started long time ago with the infamous Pentium FDiv bug. Intel quickly released Pentium MMX and said that this is the biggest invention in computing ever but the truth was that increase of performance brought by MMX o plain zero! Why? Because software was not designed to use the MMX feature. Even today only few programs are MMX optimized. But then why Intel released and advertised the Pentium MMX? To convince customers that purchased the flawed processor to upgrade to a less flawed processor.
The problem cost Intel close to 0.5 billion to put right, largely through replacing affected silicon, although it paid a higher price via lost credibility among its user base.

Interesting fact: ever wondered why Intel stopped using the logic numeration (286, 386, 486, etc) and used Pentium instead of 586? Because Intel wanted to put a trademark on their CPU to kill the competition. But they ware not allowed to trademark a name made up of numbers only (reference).

Pentium F00F bug

Intel SandyBridge bug - A serious bug that affected any mainboard with SandyBridge chipset and some i5 and i7 processors purchased after 9 January 2011. This bug cost Intel $700 million to fix this problem.

Security vulnerability in all x86-64 Intel processors

Intel TSX bug - This is a recent discovered bug

Feeding my carnivorous plant (Slow motion)

This is a Venus Trap and it is 2 years old.
Despite what the Internet says it survived the winter without going to hibernation.


This is a close up:

And this is the feeding process in slow motion!

How to make VirtualDub open/edit mkv, mp4, flv, mov and other file formats?


In order to open MP4 (and other video files) in VirtualDub you need a plugin called 'Virtualdub FFMpeg Input Plugin'. 

Installation:
Download the plug in and unzip it in VirtualDub's folder. The ZIP contains two folder one for Windows 32 bit and one for Windows 64 bits. You can delete the one that you don't need.
In my case, the plug in installed looks like this:

c:\Program Files\VirtualDub\plugins32\FFInputDriver.vdplugin
c:\Program Files\VirtualDub\plugins32\ffdlls\avcodec-55.dll
c:\Program Files\VirtualDub\plugins32\ffdlls\avformat-55.dll
c:\Program Files\VirtualDub\plugins32\ffdlls\avutil-52.dll
c:\Program Files\VirtualDub\plugins32\ffdlls\swscale-2.dll

This  plugin is freeware and open source.
And yes, it also works with H264 (H264 MPEG-4 AVC) movies.

Enjoy
:)

IF YOU ARE AN INMOTION HOSTING CUSTOMER READ THIS!!!

IF YOU ARE AN INMOTION HOSTING CUSTOMER READ THIS!!!


InMotion Hosting offer such horrible services. In time their reputation web down so they had to create a puppet company called.... Web Hosting Hub.

Here is some proof: Click the Support button it will take you to a page that has InMotion Hosting logo: https://chatwithourteam.com/licence/1001/open_chat.cgi?lang=eh&params=HUB%20HUB%20HUB%20-%20WEB%20HOSTING%20HUB%20-%20HUB%20HUB%20HUB&groups=0


Here is more proof (chat transcript)

Shea R.  Web Hosting Hub

Chat session started at 3:25:53 PM

Conference ID: MSNMN3O

Shea R.: Hello catalin. How may I assist you?

catalin: hi

catalin: what is your affiliation with inmotionhosting?

catalin: are you partner?

catalin: are you reseller of inmotion hosting?

Shea R.: Hub and InMotion are actually sister companies. They are two separate entities but share the same support staff. So Hub is not a Reseller by any means.

Shea R.: By the way, are you inquiring for possibly transferring a site to us or would this be for a new project for you?

catalin: ok. i had a terrible experience with inmotion.

catalin: left one year ago.

catalin: so, not interested.

I took my money back immediately and went somewhere else!





MORE LIES!

Please note that Web Hosting Hub has a web page where it compares itself with its concurrency but the comparison is a lie. Because Web Hosting Hub offers only 60 days money back guaranty they wrote that BlueHost (and others) offer only 30 days. So they look better than BlueHost.

Actually BlueHost offer unlimited money back guaranty.
The fact that Web Hub uses such deceptive techniques tells a lot about the way they do business.

Total Commander 8.50 is here. There is a HUGE list of new features


So, what's new in Total Commander 8.50? The Ghisler.com web site shows a difficult to read list of changes: the new features are mixed with the bug fixes. Here is the easy to read (only new features) list:
