SQLite is a SQL powered relational database that is implemented using a file on disk, rather than a client server. This means that, among other things, you don’t need a standalone process to run a database, and it also makes backups easier.

A few weeks ago, support for sqlite landed into Known.

I put together this patch primarily to scratch my own itch; I was having to set up a lot of Known based for testing as part of client projects, and I needed a way to quickly swap around configuration and data sets. I also figured it’d help out the number of folk out there who run their Known sites on devices like the Raspberry Pi.

Usage

Firstly, make sure you’ve got SQLite support built in to php:

apt-get install php5-sqlite
php5enmod sqlite

Then, you need to modify your config.ini

database = 'Sqlite3'
dbname = '/path/to/sqlite.db'

filesystem = 'local'
uploadpath = '/path/to/upload_directory/

The first two lines tell Known to use SQLite for the backend database, and where this database lives. Note, that this location needs to be writeable by your web server user (usually www-data) but, for obvious security reasons, should be somewhere outside of your Known docroot, so that it can’t be downloaded!

The last two lines tell Known to use a disk based file store for pictures and other uploads. This is important as the SQLite engine currently doesn’t support file storage in database like the Mongo engine does.

That’s it! Fire up your browser and visit your site. All being well, Known will automatically create the database and set up the schema.

Bug reports and patches to the usual place!

So, a few weeks ago I hacked together some logs for the #knownchat IRC channel.

I accomplished this by hacking together a very simple IRC logging bot. This bot will sit on an IRC channel and output logs in github friendly Markdown (so you can post them to a repo and give people an easy way to read them).

Since it was just as easy to write a flexible bot than a single use bot, I thought others might be interest in it.

Usage

The bot isn’t fancy, but it does the job.

It only supports logging of a single channel per instance, but it will interface with a nickserv server to identify itself, and will log each day’s activity in a separate file (in nicely sortable YYYY-MM-DD.md format) in a directory per channel.

Fire it up in a screen on an always on machine and you should start collecting logs straight away. To create the logs for #knownchat, I turned it’s channel dir into a git repo, and periodically push on a cronjob, but you might find other ways of doing things.

To keep things quiet, it’ll only log chat, not channel messages (leave/join etc).

Hopefully someone else’ll find this useful!

Sitemaps are specially crafted XML files, usually located at https://yourdomain.com/sitemap.xml, that help search engines better crawl your site.

It came up in conversation on IRC that there was a need for a sitemap plugin for Known, and because such a plugin would be useful to myself as well as others (and because I had a little bit of time while waiting for a painfully slow set of Vagrant builds, so I thought I’d put something together.

So, over on github, I’ve put together a quick plugin that will automatically generate a basic sitemap plugin for your site, as well as update your robots.txt accordingly.

When you first visit your sitemap.xml file a sitemap will be generated and cached. When you create new posts, this file will be automatically updated.

It’s pretty simple at the moment, but as usual, pull requests are welcome!
