US-CERT warns of guest-to-host VM escape vulnerability

Summary: The vulnerability affects 64-bit operating systems and virtualization software running on Intel CPU hardware. The U.S. Computer Emergency Readiness Team (CERT) has issued an alert for a dangerous guest-to-host virtual machine escape vulnerability affecting virtualization software from multiple vendors. The vulnerability, which affects 64-bit operating systems and virtualization software running on Intel CPU hardware, exposes users to local privilege escalation attack or a guest-to-host virtual machine escape. From the advisory : A ring3 attacker may be able to specifically craft a stack frame to be executed by ring0 (kernel) after a general protection exception (#GP). The fault will be handled before the stack switch, which means the exception handler will be run at ring0 with an attacker’s chosen RSP causing a privilege escalation. Affected vendors include Intel Corp., FreeBSD, Microsoft, NetBSD, Oracle, RedHat, SUSE Linux and Xen. The US-CERT advis...

Time for tech--->Redhat vs Ubunu--->ubuntu's problem

Redhat (as a company) is stable, professional and secure. They are right in line with thier target market. Synced well. Canonical/Ubuntu is unstable, immature, and insecure, they have no clue what thier target market is. Not in sync with thier userbase. ubuntu keep going after markets where it's unstable, specially for a free product. Linux is seen as a power user's OS.... It is no way being seen as an OS for gramma to get on FB and play farmville with her sewing buddies. That market is slim pickings. They are pulling a nintendo.... neglecting thier core users to go after new things.... the grass isn't greener on the other side. it may be an 'emerging market', however even that is stagnating. those grammas will want more from thier setup once they learn more.... Canonical/Ubuntu's image is also arrogant and they feel like thier on this "grand mission" to "humanize" linux.... but it gets to thier heads and anyone that challe...

Time for tech--->Mac vs PC vs Linux--->what is better for me?

 many people ask me this.... I am pretty unbiased, as I like a little of all 3 camps. Here's a guide to help you choose and what I think about each platform Apple Mac OSX: + *solid hardware that lasts long time *can run photoshop and a lot of creative software *the OS is secure (according to specs so far, however the increasing popularity may change this) *you will look better in the eyes of the people that care about that kinda thing *bootcamp will allow you to run windows on it - *more expensive *lack of games *os needs a lil of a learning curve (not too bad though) *Os has it's customization limits *the "hip" culture of it might turn people off sometimes Windows based PC: + *lower cost of entry *software selection *customization is medium *more hardware choices *better bang for the buck on hardware *better for gaming - *security isn't the best, however you can secure it pretty good *licensing costs are kinda high for consumer versio...

time for tech--->Firefox 5.0 has been released!

Update... I got the scrolling addon, the screen capture one to work! Here's how I got that to work: save the add-on .xpi to your desktop you must navigate to the addons page (not using the addon browser, but going to the ff addons site) and right click on the download button>save as> save the xpi file then: rename the .xpi to .zip open the zip and extract the install.rdf open the install.rdf with any text editor find 4.0.* could be any version number edit to 5.0.* save and put back in zip overwriting the original and save zip rename .zip back to .xpi open firefox and "install add-on from file" find modified .xpi  So this is how you get those addons working that won't work in the latest version of FF! easy and nice! installed.... some critical addons not working like my realplayer one and my smooth scrolling one.... will wait a lil to use it... Here's a lil performance graph: 20 tabs, 25 browser actions, flash/html5 not loaded yet: will...

time for tech--->Microsoft Has Acquisition Deal With Nvidia

This site has reported this: what about apple and linux now? driver support could be bad now!! this is a scary prediction.... we now have microsoft+nvidia we now have apple+intel we now have linux/droid+AMD a tri-opoly.... intel reads this and announces that they will step up GPU efforts and have stronger alliance with apple amd reads this and works better with linux as a response and helps fuel development allies with google. The thing is this could also create higher prices for the consumers, due to the pressures nvidia has with microsoft. Linux driver development with nvidia will be shafted as a result and AMD might take advantage of that and help them. intel will work stronger on thier GPU developments and create discreet GPUs that will be more powerful then thier current GMA series.  They might have a stronger alliance with apple as a result and apple will gain more ground marketshare
