Some times you work on your code or configuration files and realise you have made more changes than sensibly fit into one commit. Using patches you can easily select only the changes want rather than adding all the changes in a file. You dont even have to create a seperate patch file.

Once you have more buffers (files) open than windows in Emacs, then having a quick way to cycle through buffers is invaluable. Even with 4 windows open, I still find myself using IBuffer, C-c C-x, many times.

Sometimes I just want to switch between the current and previous buffer in the same window. So this is how I tweaked my Emacs configuration (based on Emacs Live) to cycle through buffers.

Adding images to a blog post helps the audience undersand what the will get from reading the article and if it will be relevant for the. Images also aid the understanding of the topic you are covering, especially if you are explaining something technical or more complicated.

The default theme for hexo only provides a single image style, so here I will create several styles of image to help convey the topic and details of every post.

The font that comes with the default hexo fault is quite nice, however, I like using the Ubuntu font especially for code. As the Hexo theme uses Google fonts in some places already, then it was really easy to change which one Hexo uses. Here I will show you how to change over to the Ubuntu font family for text and sorce code using Google Fonts.

Hexo has a bit of a refactor from version 2.6 onwards to make it a bit more flexible with regard to the node modules it uses. So when you create a new Hexo project you have to add some module to that project before you can generate your site. This is an easy step as its managed by the Node package manager (npm).

There are more details about migration steps on the Hexo Github project.

Here are the essential details and options for upgrading to Hexo 2.6 onwards.

The hexo theme shows code in a solid black box with syntax hightlghting to match. It gives a nice contrast to the rest of the content, however I wanted to add curves to the corner of the code boxes. I also wanted to add a margin / padding around the code box so it did not touch the edges of the post.

Whilst I like many aspects of the Hexo theme used to generate static websites, it does seem to have a lot of redundant space. So here are a few aspects of the them I have changes in order to get more of the actual content showing on the page.

FontAwesome provides a lot of icons you can use in your website instead of including image logos of various sizes. There are icons for twitter, linkedin, Github and RSS feeds. Using these icons keeps your website fast on any device or network.

I’ll explain how I configured the standard Hexo Landscape theme to add icons in my blog website navigation bar, each icon linking to the developer related sites I use such as Github and Twitter.

You can use Git to manage version of your content effectively. You can also use Git to manage any changes you make to the theme you use.

Rather than keep all these seperate changes in one repository, you can use Git submodules to manage your theme and content changes seperately.

Git is the version control system of choice by most developers, however when it comes to Git Submodules there is some contention as to their value. I have used them successfully and when you understand where they fit in you can use them to benefit your own projects too.

I’ll explain what Git Submodules as well as why some developers are using them and some developers warn you not to.
