Blog website crawlers and bots in Apache2

Found a couple more bots crawling my website, and from the look at online resources it seems I catched a few of the bad guys. Crawlers which ignore the robots.txt standard, and just crawl a website for content. Decided to do something against it, and added a filter in Apache2.

openHAB and Telegram Bot

openHAB 2 comes with a Telegram binding which allows to run a Telegram Bot. This bot can both send messages to users and groups, and can receive commands and respond to them. That’s useful: your home automation system can send all kind of details to your mobile phone.


New PostgreSQL pg_docbot is live

Last night a long-running project of mine went live: pg_docbot v2.

For years, Jan Wieck provided a helper bot (rtfm_please) in the #postgresql IRC channel in the freenode network. Because of protocol changes in the freenode network, this bot was no longer functional. Together with some others we decided to write a quick and dirty new bot. As it is with dirty hacks, not everything was optimal: after timeouts the bot was not able to reconnect - more exactly the POE framework did not even recognize the timeout. Also extending the bot and adding new functionality was complicated. For a while I collected all these problems in my personal bugtracker and about two years ago I started a full rewrite.
