Working software over comprehensive documentation” is one of the Agile Manifesto’s four value statements. You may well be one of those people who believe that documentation is a waste of effort because it’s outdated as soon as it’s created. You might believe that your code is self-documenting or that UML diagrams belong in the 90s. But it’s a mistake to think there’s no value in documentation.

You may have heard that, if you’re investing in stocks, you need to have a diversified stock portfolio. But what does that even mean? It means to own a variety of multiple stocks.

Forwarding iDrac Remote Console ports over SSH Tunnel (BASH)

iDRACs (and other BMCs) should never be put directly onto the internet. This does mean, though, when trying to access a virtual console you need to go via some sort of a jumpbox. I'm not a fan of inconvenient approaches (like using Teamviewer to connect to a machine on the same network) and would rather, where possible, just set up an SSH tunnel with the appropriate ports forwarded. This command does just that, allowing use of the in brow..

Install multiple packages with apt in a single task (Ansible)

When building a system with ansible you'll commonly want to install a variety of packages. Sometimes these will be broken up into individual tasks within various roles, but sometimes you want to install multiple packages as a single task (for example - install useful utilities). This method allows a single task to install multiple packages and their dependancies (the named packages will be installed sequentially) using apt. Read more…

When installing multiple python libraries with pip, you might not want each to be an individual named task within ansible. This method allows you to have a single ansible task and install multiple libraries along with their dependancies (they'll still be installed sequentially) Read more…

On occasion, you might need to identify the IP address of the machine being ansibled. However, there are various scenarios (AWS instances, alicloud instances, NAT etc) where the public facing IP of your machine may not necessarily be bound directly to an interface on the system you're running ansible against. This simple role places a call out to a Web based endpoint and sets a fact based upon the response so that you can use it later (fo..

My daughter is 3¼ years old now. About the time that she was born, I decided that I needed to make a small change in my language. Whenever I felt the urge to curse, I would say a food’s name. For example, after being puked on, my reaction would be some variant of: “PASTA”, “PASTA BOLOGNESE” or other pasta’s favorites. As time went by, I got better and better at expressing emotion through increasingly disturbing food references. My current....

Overriding tcUrl and other options with ffplay (BASH)

Various non-standard RTMP applications rely on the the values of attributes that are commonly passed in as part of a PLAY call, such as tcUrl, pageUrl etc. Sometimes this is for authentication (and content protection) purposes, sometimes it's to implement a DNS name based namespace so that different domains can share the same app. With ffmpeg and ffplay it's possible to override tcUrl and other variables with a command line option Read m..

Over the weekend we migrated a huge amount of code to the new build servers. In this post I’ll try to cover three separate things. I’ll explain the architecture/history and process of the migration. What worked, what didn’t work and lessons learned. And finally how this will impact Codename One users moving forward. I’ll start with a bit of history to explain the background and motivations. We formed Codename One in January 2012. Back the..

Narrowing utilities are a wonderful way of increasing productivity. I have a few workflows using Emacs's Helm framework. There are great productivity boosters like Alfred and Quicksilver for macOS, with batteries included. If you're a tinkerer, you'd enjoy the powerful Hammerspoon . Like elisp gluing all things Emacs, Hammerspoon uses Lua to glue all things macOS. You can build your own narrowing utilities using chooser and a l....
