Your blog and presentation preparation can be done in parallel. However, you will find it easier to first complete a draft of your blog post before tackling your presentation slides. Get a full grasp on your topic before you jump into making slides.
Your blog post should be on something very specific. Examining just a small technical subset of material allows you to write and speak as an expert on that topic. Avoid writing a post that tries to encompass something in general.
The topic can be on anything you have learned so far in the Power Code Academy. The post should be more in-depth than any particular lesson has explained in learn.co. It may also be on anything related to the content so far, but not explored inside the curriculum itself. Use Ruby documentation for motivation.
Possible blog subject areas include: Ruby inheritance, Modules, refactoring, good Object Oriented design, a particular set of Ruby methods, a solution you discovered while working on your project, researching error messages and backtraces, etc.
Your blog post must utilize code snippets to help explain your topic. These code snippets can be of Ruby or Bash.
Aim towards making your technical blog post about a 2-4 min read. However, more important than length is substance. Your post should be written professionally, as it will not only represent you, but Power Home Remodeling Group at large. When editing your post, make sure that the information is presented in easy to read chunks. Break up long paragraphs into clear digestable pieces of information. Make your post as easy to understand as possible.
Power hosts a technical blog site called "Tech at Power" at https://blog.techatpower.com/ . This is hosted on the Medium platform. To add a blog post, you must create a free Medium account if you do not already have one.
You may start your post on Medium. It will save each change you make, and you can publish when you finish. Remember to use upticks to create block and inline code snippets. Medium can be a little contrary with this, but both styles on code snippets do work on their platform. Feel free to include pictures too, but that is optional.
Some online tools that may be helpful are Grammarly and the Hemmingway Editor.
Before you start building your presentation, you must watch this video on delivering good technical talks. The accompanying website to this talk is speaking.io. Speaking.io is a superb resource on creating good presentations.
Your presentation will be a "Lightning Talk". Meaning, it will not be a full length technical presentation like the resources above describe. It should just aim to be an informative blurb about 5 minutes in length.
At Power, we use Keynote to create all our slide decks. Although short, your presentation should employ at least 3 different slides of info. Slides must be widescreen (16:9) in format. To change this setting in Keynote, click "Document" in the top right corner, then find the "Slide Size" select bar and choose "Widescreen (16:9)".
