Some years ago I participate in a challenge. It went fine and all participants got some feedback afterwards so we could figure out what we had done wrong. As part of that feedback, the question of re-using parameters within function rose... so I decided to look into the details.

LINUX

Not so long ago I had to configure a machine following some strict rules. It was pretty painful and, when I was done, I was asked to provide an image of the configured machine to some remote team to do some checks on it. The machine was installed in a 1 TB disk, so making and image and send it around will require quite some time (either to transfer the file or to wait for the post to deliver some physical storage device).

Anyway, if you are reading this, you have probably noticed that I can now post without a header image. Header images are really nice and give great visuals to the posts. But, sometimes, I have an idea to write, or even I have already written the post and it takes me a while to finally publish. Just because I cannot find a nice picture to use as header.

As you may have noticed, I failed to publish the SUP entry for December. Well, end of the year is always hectic and I had troubles getting some time to write about what happen during the month before the end of 2016. But, do not worry. This is what have happen during December
