New GNU Screen – 4.2.1 – first in 6 years.

Filed in LinuxTags: , ,

For all you console junkies (the command console, not that WeePlayBOne thing), Amadeusz Sławiński and friends have released the first new update to GNU Screen in six years.  I’ve pulled the source and compiled it (under CentOS 6.5, GCC 4.4.7, Kernel 2.6.32, bash 4.1.2).

You can find the new source here: GNU Screen 4.2.1

I’ll be putting the new options and features through their paces over the next few days as I go about my day to day Ops duties.  I use screen much more now than in the past, so this should be an adventure.

I’m interested in hearing other’s take on the new features.  Drop them in the comments below.

And… Another one. This time in Flash.

Look.  Another security exploit.  This time in that bastion of ultimate security.. er.. hang on.. what’s this?  It’s in Flash?  This is news?  Oh, a *NEW* one in Flash.  Got it.

Ok.  Where were we?  Looks like another security vuln in the wild.  This one’s in Flash and effects all three major OSes.  Yep, that’s right you penguins..  Linux is included in this one.  So get your YUM and APT repos spun up and update those boxen.

Krebs has the details here: Adobe Update Nixes Flash Player Zero Day

So there you have it.  Two major web exploitable vulns in two days.  Waiting for the other two shoes to drop; Java and Acrobat.

PS: Is it strange that I’m using a terminal window to cut/paste text from websites to strip it of hidden formatting?  Yes?  It is?  Good.

On the cost of Windows vs. Linux

Filed in LinuxTags: , , ,

Just posted this to slashdot and thought I’d share it somewhere it’ll actually get read:

in re: Windows vs. Linux costs to implement and why Linux will never be “free”.

The ‘free / not free’ argument is meaningless. You will pay for licenses and support from Microsoft plus the cost of IT support staff and engineers. You will also pay either support contracts from Redhat, etc… plus IT support staff and engineers or pay more for better IT support staff and engineers and use community supported Linux.

When all the bills come due, you’re going to pay about the same for the same functions and scale regardless of the OS. The curve for the cost of Linux flattens out earlier as you move into the hundreds of servers or very large or widely dispersed infrastructure, but the cost of a competent staff to support Linux is higher.

It is easier to support Windows with less knowledge and experience, therefore making Windows staff less expensive. In truth, there are probably 10 middling competent Windows engineers for every solidly competent Linux engineer in the marketplace. The Linux engineers tend to stay employed longer as well.

When all you’re looking at is the base cost of a software license, or piece of hardware, then you’re not looking at the most important, vital and expensive part of the bill; the people.

Linux admins and engineers I’ve worked with and around have tended to be problem solvers by nature. Windows admins and engineers I’ve worked with and around have tended to be implementers by nature. They each have their strengths and weaknesses and you have to pick based on a strong understanding of your company’s needs, not just on the flashy marketing tripe from Microsoft or the FOSS communities.

TL;DR: In the end, Windows and Linux will cost you the same. Which one is best for your company depends entirely on your company.
