Creating a new disk Image
This will be the main HDD in the virtual image, so make sure to give it as
much space as youll need. Since were building a kvm image, we can use a qcow2
format for disk images. Qcow2 is an expandable image format, so itll only
take as much storage space as its actually used within the image.
$ kvm-img create -f qcow2 image.img 5G OS Installation
Download the iso file of the Linux distribution you want installed in the
image.
$ wget http://releases.ubuntu.com/karmic/ubuntu-9.04-server-amd64.iso
And start the installation process:
$ sudo kvm -m 256 -cdrom ubuntu-9.04-server-amd64.iso -drive

Java vs. Python: Which One Is Best for You?
By Kevlin Henney
Few questions in software development are more divisive or tribal than choice
of programming language. Software developers often identify strongly with
their tools of choice, freely mixing objective facts with subjective
preference.
The last decade, however, has seen an explosion both in the number of
languages used in production and the number of languages an individual
developer is likely to employ day to day. That means that language
affiliations are sometimes spread more loosely and broadly across different
codebases, frameworks, and platforms. Modern projects and modern developers
are increasingly polyglot—able to draw on more languages and libraries than
ever before. Informed choice still has a part to play.
From that bustling bazaar of programming languages, let’s narrow our focus
to two survivor... (more)
Building Effective, Secure Container Delivery Pipelines with Docker, rkt et
al.
Opinions on how best to package and deliver applications are legion and, like
many other aspects of the software world, are subject to recurring trend
cycles. On the server-side, the current favorite is container delivery: a
“full stack” approach in which your application and everything it needs
to run are specified in a container definition. That definition is then
“compiled” down to a container image and deployed by retrieving the image
and passing it to a container runtime to create a running instance.
Here, I’d like to talk about how we can apply lessons from experience of
shipping code using many different formats in order to build effective,
secure Container Delivery pipelines.
The way it’s described above, container delivery does not sound much
different from most other packagin... (more)

Many new programmers struggle when it comes to selecting their first language
to learn. Which is easiest, the most professionally useful, the most
newbie-friendly? Lets find out by showing you a range of options, their
strengths and weaknesses, and some information about the most common
programming languages in demand today. At the end, we’ll make some
recommendations and you’ll understand a bit more about why they were
chosen.
The Task At Hand
Every job requires the right kind of tool, and each programming language can
be thought of as a separate tool. Just like some tools are good for
hammering nails, driving screws, and leveling screws, some programming
languages are innately more suitable than others for tasks like designing a
website, interpreting text, or reacting to user input.
Lets go through a few common use cases:

Five of the Best Programming Languages and Frameworks for a Small Business
Choosing a programming framework for a small business can be overwhelming-
there are so many. Here are a few of the best choices, to help you get
started.
Ask a room of ten developers which programming framework is the ‘best on
the market,' and you're liable to receive ten different answers. Each
developer will sing the praises of a different language, and each one will
very probably feel that theirs is the only logical choice. The most confusing
thing, though? Each and every one of those developers will be correct.
Wait, what?
I'll be blunt: there is no universal programming framework. The language your
organization should work with - whether it's for web development, mobile
development, or traditional development - depends entirely on your unique
situation. The perfect choice for one busine... (more)

The Importance of Monitoring Containers
By Kevin Goldberg
With the rise of Docker, Kubernetes, and other container technologies, the
growth of microservices has skyrocketed among dev teams looking to innovate
on a faster release cycle. This has enabled teams to finally realize their
DevOps goals to ship and iterate quickly in a continuous delivery model. Why
containers are growing in popularity is no surprise — they’re extremely
easy to spin up or down, but come with an unforeseen issue.
However, without the right foresight, DevOps and IT teams may lose a lot of
visibility into these containers resulting in operational blind spots and
even more haystacks to find the presumptive performance issue needle.
If your team is looking towards containers and microservices as an
operational change in how you decide to ship your product, you can’t afford
bugs or software issue... (more)

Red Hat Enterprise Virtualization for Servers significantly updates
management capabilities and supports giant virtual machines.
The release of Red Hat Enterprise Virtualization 3.0 signals that 2012 will
be the year that IT managers at organizations of all sizes have real choices
to make when it comes to virtualizing workloads in the data center. RHEV 3.0
and the Microsoft Windows Server 8 release candidate both offer a challenge
to the currently unrivaled data center virtualization lead position held by
VMware vSphere 5.
Until now, IT virtualization managers could use VMware vSphere without much
question to run workloads of all types. RHEV 3.0 successfully challenged this
operating assumption in tests at eWEEK Labs. The revamped ... (more)
