Docker from Scratch, Part 3: Entrypoints and Ports

In the last post we used the RUN statement in our Dockerfile to setup and install software in our container. This saves us the trouble of creating build scripts that we need to run each time we start the container. We still have to specify the command to run when we start the container. What we want to do is eliminate that so we have less to remember each time we use the container.

Docker from Scratch, Part 1: Installing and your First Container

The last few months I’ve been engaged in a quest to understand something new to me. Since the mid-2000s, I’ve been using virtualization technologies to run classroom environments, test software, and run local web servers for development. First, it was using VMware Player, then Server, and today everything I virtualize runs on the open source Virtualbox. So when I heard about containerization, I was stunned.

Unnecessary Toys; North Shore Therapy

Test drove a Prius C over the weekend. It felt so much like my old car, but a hybrid. If I needed a car, and if it wasn't red, I might be driving again today.

I also did some scooter shopping. While they're all conventional drive vehicles, the lower cost, and summer-only use encourages me to consider getting one. When bought used, they are only about $3k for a well-maintained bike.

And the world rewards you for it

It’s not that I’ve forgotten how to self-care, it’s that I’ve actively dismantled my ability for it, not just for days, weeks, or months, but years. There was a moment during high school where I went, “if I’m only worth my ability to work, then to hell with how I feel about it.” I became not only a hard worker, but an obsessive, relentless worker that forgot about vacations and most concepts of working hours. If it had to be done, I’d be the one to do it.

Feeding the Monster

Social networks don’t want you to be able to block people. 

Imagine a social network as a the monster plant from Little Shop of Horrors. It doesn’t care about you, or your friends, or anyone. It just wants to be fed. How do social networks feed? By the posts, reblogs, follows, likes, profile information, and anything else you shovel into its gaping maw.
