Writing tech articles

This is a description of how I write tech articles for various blogs. Hopefully someone else will find this useful as well.

Create a Gist for the article

When I begin writing a new article, I create a new [GitHub Gist][gist] for the article files. The Gist contains a file for the article text and code examples related to the article.

Pushing to Multiple Git Repos

If a project has to have multiple git repos (e.g. Bitbucket and Github) then it's better that they remain in sync.

Usually this would involve pushing each branch to each repo in turn, but actually Git allows pushing to multiple repos in one go.

If in doubt about what git is doing when you run these commands, just

Steganography: the art of hiding in plain sight. Messages specifically. These are a series of tools that aid in embedding messages in digital files.

While steganography provides obscurity, it does not strictly provide security. Before hiding your message using any of these scripts, it's suggested you encode your message (try PGP/GnuPG encryption or put it in a TrueCrypt container if you're at a loss).

`pngload.py`

The PNG file format divides the image data into 'chunks', and allows for additional, private chunks to be added by image editors. This script takes the message you wish to embed and saves it as binary data in such an ancillary chunk.

The files being embedded are compressed with bzip2 compression if they're not already a bzip2 archive. This is different from the `
