The other day I was having a nice chat with a good friend of mine. The conversation was mainly about orchestration and scheduling of containers in cloud environments. Needless to say, Kubernetes was mentioned. The actual content of the conversation is irrelevant for this post. But there was a comment he made about another team that took them 8 months to have a plain Kubernetes cluster up and running in AWS (Custom EC2 isntances).

When I was a kid, I took a couple of computer courses and, on those days, all was green phosphorus monitors or gray scale ones. Till the day all changed: someone brought a PC that was CGA capable. We were all stunt with the “new” 4 color modes. The clasical mode comprises black, cyan, magenta and white and has become a legend. The other mode I have met was black, red, dark yellow/brown and green.

One random morning, having a walk through this wonderful city in The Netherlands. The following gallery has been produced thanks to the great work of Li-Wen Yip’s Hugo Easy Gallery. Great job!

As we saw in the previous part, this chapter will define the project in details, and will explain the current situation and what I think are the next steps I should take. The first thing we need to remember is the description of the environment we did in the previous part. But in case it cannot be remembered, here is a summary: The environment is composed of 4 VMS: 1 CPU 512Mb of RAM 2GB HDD The following names and services distribution: Plan9n1: cpu server, file server, authentication server Plan9n2: cpu server Plan9n3: cpu server, file server (replica) Plan9n4: cpu server, venti server (filesystem archiver) To be more clear, please, see the following diagram:

Again, a newbe here. Exploring this awesome OS: QNX RTOS. First, I think the concept of “RTOS” should be explained. At least, what I understand an RTOS is. RTOS stands for RealTime Operating System. The idea, very roughly, is that whatever event comes into the system, it should react to it and give a proper response within 1ms, in other words, the processing boundaries (time that will take to process something) are known in advance.

I wanted to understand how HDR photography works so I thought the best way to fully understand it is to try to code something to apply the algorithm and see the results. As GIMP has a very powerful framework for scripting, I thought this is a good platform to do it. GIMP support 2 languages: Python and Scheme. To make things more interesting, and go back to the days of Lisp programming, I chose Scheme for this.

Disclaimer alert: as this was something we did at work, I will use code names for applications, calls, etc. There will be no real data shown. I need to keep the privacy statement. But Extrahop is an external product. Yesterday I helped a friend in building some custom monitoring for an application we support (from now on I will call The Application aka TA) and a specific call (Which from now on will be The Call aka TC).

As the title suggests, follows the list of parts I really used for this project. Let’s get started (no special order): Pickups: Seymour duncan JB Model Humbucker: lovely pickups, I would like to try others though, but these ones are really good (IMHO). One thing I really like of them is that they sound great and are passive. I had active ones in the Warlock, and honestly I don’t see much difference.

I am not a musician. I am sure I will never be: I have no rhythm, no sense of melody and no ear for music. I know almost nothing about music theory and I am quite bad applying it. But there is something the new technologies are making possible: use musical instruments to make nice noises. In my case, what I really like is an electric guitar with a heavy distortion.

For most of the people, Plan 9 is an underrated film directed by Ed Wood. But for others, who have seen the light, there is another Plan 9…. The operating system. Created by the same great minds that crafted and designed Unix and C…. First of all, I am not an expert in PLan9 but a curious engineer that is interested in grid computing. I will write another post about my thoughts about this awesome operating system, but if you want to have more information now I recommend visiting the official documentation from the creators themselves:
