A number of folk have been starting to see some more spam comments appearing in their logged out comments section, posted by bots.

I’ve already written an Akismet plugin, which has helped with some of it, and Known core has also been extended with some countermeasures. However, I have wanted to see if I could do some more.

When I was wearing one of my other hats the other day, I had the opportunity to play with the new Recaptcha 3 code, and I thought I’d bring it to Known.

Recaptcha 3 takes a new approach to detecting bots. Rather than getting a popup and getting you to click on pictures (which is very very annoying, and hard for those with accessibility issues), Recaptcha 3 does some arcane magicks behind the scenes to determine who’s bot or not, and then gives you a score indicating the likelihood that you’re dealing with a human. 1.0 for high likelihood of a meat sack, 0.0 for a bot, and then any value in between.

Much like with spam detectors like Spam Assassin, you can then set your own threshold values and do this on a page by page basis.

Crucially, you’re never going to get a popup. Thank the Gods.

Anyway, I’ve built this out as a plugin. Out of the box, you’ll get protection for login, registration, and public comments, but you can extend it to protect your own custom forms without too much trouble.

Have a play!

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!

Like with other free software / indieweb projects, lot of development discussion regarding Known takes place on the IRC channel #Knownchat.

I lurk there, but I kept missing stuff, and besides it’s useful to have a log of some of the conversations. I think the founders were going to set something up, but since I know they’re very busy, I thought it’d be useful to hack something together until something better comes along.

So, I hacked together a quick bot IRC logging bot.

This bot outputs logs in Markdown, and I’ve set up a quick cronjob that will take those logs once a day and push them to a github repository for everyone to see.

Pending something better, I thought this might be useful. Standard caveat; these logs should in no way be considered “official” or endorsed by the project, I made them for my own use with hopes that they’ll be handy for other folk as well.
