CPU Flags and Meanings

Filed under: General Linux — TheLinuxBlog.com at 11:38 pm on Tuesday, August 11, 2009

Having a brain that is somewhat comparable to a sift for remembering acronym’s, I’m always asking a friend which (I, probably incorrectly call) CPU extension is for virtualization. So I figured I’d blog about this topic. This page CPU feature flags and their meanings clearly explains each of the flags that may be on your machine, which you can check what your CPU supports by typing:

cat /proc/cpuinfo | grep flags

Secure Virtual Machine. (AMD’s virtualization extensions to the 64-bit x86 architecture, equivalent to Intel’s VMX, both are also known as HVM in the Xen hypervisor.)

So to answer my own question SVM and VMX are what to look for when considering a CPU for virtualization. My laptop supports VMX, but my desktop doesn’t. Considering I’d rather do my virtualization on my desktop, I’ll have to upgrade my CPU. Now all I need to do is find out where to find this information for AMD processors and hope I can get a CPU for my outdated socket type. I don’t even think that it is AM2 :(

Big Box Chain Store Offers Linux Support?

Filed under: General Linux — TheLinuxBlog.com at 5:35 am on Saturday, January 19, 2008

I have a friend who works for a major big box store chain in the computer support department. I’m not going to say who, but they drive black and white bugs around and are known as geeks. Anyhow, thats besides the point. While talking the other day he said that he had got a phone call from one of the various departments and they asked if there was any one at the store that knew anything about Ubuntu Linux.

Now, I’ve seen this companies ads pop up on Linux related websites before and even on mine, but in store they do not offer any type of support. They even say on their website that the tools they use do not support Linux.

So what were they doing calling each retail store and asking for a Linux expert? They don’t train any one for Linux support would they expect to find anyone? I think they may be trying to sell hardware installation services, but when a customer complains that a piece of hardware doesn’t work they have to troubleshoot it. If they can’t troubleshoot it or verify that it works how is the service complete? I don’t  know if thats the case, I’m going to try to pick his brain some more and see what we can come up with.

Who knows, you may be looking at this companies ad right now and not even know it.

Linux+ Certification

Filed under: General Linux,Shell Script Sundays,The Linux Blog News — TheLinuxBlog.com at 4:35 pm on Monday, October 1, 2007

My Shell Script Sundays article was not posted yesterday as I was reviewing for the Linux+ Certification by CompTIA. I have been meaning to take the exam for a while not but just never got around to doing it.

I took the exam today and passed. It was comparable to the other CompTIA exams I have taken except the topic was mostly on Linux instead of networking or hardware. The questions were very reasonable some were a little tricky and had me confused about the correct way to complete a task.

I only had the LPIC certification book to review from but had read the XK0-001 book about 8 months ago. The exam description explains that it was designed to measure the competencies of the Linux Professional with six to twelve months experience with Linux. Some of the other CompTIA exams say that you should have X years of experience in a certain field but is not needed, I believe that the experience for this exam is needed, maybe not half a years worth but at least a month of using nothing but Linux full time.

I would recommend to anyone interested in collecting certifications to take this exam. Even if Linux isn’t your main concentration it will still be a valuable asset in your certification portfolio. Now I’ve passed I have to find another certification to study for and beat around the bush to take the exam. I’m wondering if I should take another Linux certification (such as Redhat, LPIC or Novell’s) or go another route like Server+ or Security+. Either way it gives me something to do and keeps my brain active.

My apologies for not getting the Shell Script Sundays article out but I have a good one lined up for next week so check back!
