Docker 1.0 Released

Omegaman What is docker? Docker is... (88 comments)

Docker is a lot of things, all rolled up into one so it is difficult to describe without leaving out some detail. What is important to one devops person might be unimportant to another. I have been testing docker for the past few months and there are a couple of things about it that I like quite a bit.

I have to explain a couple of things that I like about it before I get to the one that I really like.

1) It has a repository of very bare bones images for ubuntu, redhat, busybox. Super bare bones, because docker only runs the bare minimum to start with and you build from that.

2) You pull down what you want to work with, and then you figuratively jump into that running image and you can set up that container with what you want it to do.

3) (this is what I really like) That working copy becomes a "diff" of the original base image. You can then save out that working image back to the repository. You can then jump on another machine, and pull down that "diff" image (but you don't even really have to think of it as a "diff", you can just think of it as your new container. docker handles all the magic of it behind the scenes. So if you are familiar with git, it provides a git like interface to managing your server images.

It does a lot more than what I describe above, but it is one of the things I was most impressed with.

3 Habitable-Zone Super-Earths Found Orbiting Nearby Star

Omegaman Red Dwarfs (203 comments)

One problem that has not be determined is how do planets deal with the inherent variability with Red Dwarf stars. There are many, many more red dwarfs than other types of stars and their expected life expectancy is longer the estimated end of the universe. But their small nature makes their energy output more variable than a star like our sun.
Does the long life, and greater number of Red Dwarfs significantly boost the drake equation? Does the variable energy output reduce the drake equation?

Unfortunately, we will all probably be long dead before we find out.

CmdrTaco Looks Back on Fifteen Years of Slashdot

Omegaman Re:Long time User (see UID of three digits) Agrees (178 comments)

Slashdot has mirrored the Internet in many ways. It seemed better in the early days as the signal to noise ratio felt much lower. The past is a foreign country.

Should Geeks Skip College?

Omegaman College is important -- living proof (224 comments)

I did go to college, but I earned a liberal arts degree. I felt at the time (and still do) that colleges would be unable to keep up with the pace of change in technology and that I could continue to learn much more on my own. I also didn't want to sit in classes being taught things I already knew and could easily teach myself.

There were, of course, other reasons for choosing the path I did and I wouldn't change a thing. However, I am having a hell of a time finding a position now in the fields where I want to be and know that I am qualified to be. Employers do not find self-teaching credible. Part of my problem is where I live. A self-taught geek has greater opportunity in say, California, than in the prehistoric techno backwater called Louisiana.

Nonetheless, I am patient and will prevail. I make a reasonable salary now despite being bored and unchallenged by my position.

There are lots of other reasons besides the degree to attend a University. The experience is well worth it regardless of the degree you end up with.
