Calibre The Open Source ebook Library Manager

As many of us have been moving lately from physical books to ebooks, as they are more convenient on the go, and better for the environment. I know nothing is like a physical book, but sometime we need to adapt and benefit of the convenience ebooks bring. The challenge with ebooks that you can end up with many of them scattered on your device with no order what so ever, which make it very hard to find that ebook you were reading a month ago while looking to remember or confirm a particular piece that you read or if you wanted to share it with a colleague or friend.

Tiny Core Linux is one of my favorite lab OS

Due to the type of work I do, I have often the need for small (Actually very tiny) VMs that have a functional OS to test certain basic functionality such as connectivity and quick features of automation solutions. While I could use a full blown OS for it, I have always found Tiny Core Linux to be my favorite for this use case for the following reasons:

Tiny Core Linux Logo

1- It’s Open Source and free!!! Oh, yeah I would have not paid for other type of OS usually for lab or test use and used a try out version or so on, but it get tiring after a while to see your try out version expired and having to re-setup a new one at the time you most needed it, when running a demo!!

containerd is a great Open Source container run time!!

While Docker had been for the longest time the name you are most probably to hear when ever the discussion of containers run time come up, lately containerd has becoming so popular that you are hearing it just as often. The fun part which confuse many people is that containerd is used by Docker. The code that makes up containerd was originally part of the Docker Daemon but was abstracted from it to provide a more modular approach.

ContainerD CNFC Logo


containerd is an OCI compliant core container runtime designed to be embedded into larger systems such as Kubernetes. It provides the minimum set of functionality to execute containers and manages images on a node. It was initiated by Docker Inc. and donated later to CNCF. The Docker engine itself is built on top of containerd.

As of the launch of Wine 2.0 in January 2017, the annual release schedule that is currently maintained is established and after Wine 3.0 arrives, how could it be otherwise, Wine 4.0 is here!

What Tech Trends Can You Expect In 2013?

Technology has a short amount of time to grab our attention before it gets pushed to the side in favor of their newer, younger and more desirable models the next.

2012 saw the introduction of smarter smartphones, slimmer tablets and better wireless networks. So what trends can you expect to emerge in the next 12 months?

Hybrid laptops. The number of people who own a smartphone, laptop and tablet no doubt increased over the past 12 months. However, there might be a time in the near future where a laptop and tablet are one in the same. Dell released the XPS 12, which they market as part laptop, part tablet. The swivel monitor can sit upright like a traditional laptop, or fold on itself to only reveal the touchscreen, a la tablet. In 2013, look for hybrids like these to get the typical makeover: thinner and faster.

Install Flash Player on Ubuntu 10.04 64bit

This article will show how to install Flash Player on Ubuntu amd64 (64bit)

First of all, and to see if you have installed Ubuntu 64bit or 32bit Ubuntu, run in a terminal:
