Should I Use LVM?



Posted by: Eric Hansen
security

LVM is a nice invention when it comes to Linux and the kernel.  The easiest way to think of it is RAID without any performance gain or loss.  You're able to extend and shrink the LVM partitions like RAID but there's no benefit to it beyond that. Why would anyone want to use LVM over RAID or no...

Pricing Your Services



Posted by: Eric Hansen

I'm looking to add more services to my business, but its a tough thing to figure out...how much to charge someone, that is.  You have to look at the resources of the server and factor in not only how much you expect your userbase to use, but also the system itself. For example, I'll have a KVM...

Developing With Python: Scripts

While already covering Python for websites, it also serves a very useful source of scripting. Back in the day Perl and shell ran the playground for scripting languages.  However, now there's a whole mess of new friends to meet in Python, Ruby, PHP (though its pretty old too) and more. Python...

Developing With Python: Websites



Posted by: Eric Hansen

Ever since I started using Python I fell in love with it.  Unlike Perl I could wrap my head around how to do even simple things, and for scripting it was like Bash on steroids.  Then not after long I disocvered you can develop websites with it as well (either through things like Pelican or...

Your Phone Doesn’t Dictate You

For many years I've used Android (since 2.2 came out and was new).  At first I absolutely loved it.  It was new, it was fast, it offered a lot to me and my growing intents.  Heck, it was nice to have a phone that didn't use WAP for browsing! Now, though, Android has really turned me away from...

If you're looking ot have a true server without the added expenses of managing a physical server, then a KVM is right for you. KVMs offer all the benefits of owning a physical server without the overhead of managing the resources.  Lots of hosting companies offer them and especially with it...

The Linux Verisoning Issue



Posted by: Eric Hansen
security

Linux 3.0 was a big deal in most peoples' eyes.  For as long as I can remember using Linux (since 2004) the kernel was at 2.y.z.  3.0 was only released either last or this year, even. Then Linus made the announcement that 3.0 wasn't going to be anything more than a usual patch fix (i.e.: no...

Are Certifications Worth It?



Posted by: Eric Hansen
security

Back when I was going to ITT for my associates everyone stressed the importance of certifications.  When looking at the job market it made sense, too.  Most entry-level positions were asking for A+ or Net+, even some wanted CCNA (...no.) Looking at the job market 5-ish years later a lot has...

I'm not sure how the job market is everywhere else, but near Detroit where I live it is like trying to find a horse in a barn.  There's jobs everywhere but everyone hiring is either a recruiter or nit picking on the details it seems. Don't get me wrong, recruiters can be the best tool anyone...
