Do you need to store that IP address?

I was reading this ACLU blog post about how DreamHost was served with a warrant to hand over IP addresses of some 1.3 million visitors to a website they host, and it got me thinking: do websites really need to store IP addresses of their visitors?

There are a lot of VPN companies such as Private Internet Access that advertise far and wide that they explicitly chose not to keep any logs. The idea is that if the VPN provider is served with a warrant for user activity, they would have no data to hand over, because they never stored anything in the first place. Why don't websites do that?

Go Plugins and Avoiding Cyclic Dependencies

The other day, I started a project to eventually replace the backend of Kirsle.net with a Go program instead of the current Python one (Rophako). It will support a similar feature set (being modular with even the core functionality, like user accounts and web blogs, being served by built-in "plugins" and allowing users to extend it with their own plugins).

The plugin system will support both compile-time plugins (your main.go imports and registers all the plugins you need when compiling the binary), and run-time plugins using Go's plugins from *.so files support.

This post will focus on the former, compile-time plugins, and how I ran into a cyclic dependency issue and worked around it.

Why Tabs are Better than Spaces

This is going to be yet another blog post in the "tabs vs. spaces" holy war that software developers like to fight about. I generally prefer tabs over spaces, but for certain types of programming languages I do use spaces instead of tabs.

I indent my Python and CoffeeScript with spaces, but all the other languages I use (Perl, Go, JavaScript, HTML, ...) get the tab characters.

Poor Man's ngrok

Recently, I was developing a Python/Flask app to implement Web Hooks for a third-party API that I was working with. The API recommended the use of ngrok during local development so that the server running on your local computer could be accessed publicly over the Internet (so that their API could reach yours).

ngrok is cool and all, but for their free plan they randomize the subdomain they give you every time you start the program. This meant I always had to log into my API account and change my Web Hook URL each day.

What ngrok is doing is nothing new: I've written about using SSH to forward ports between machines, and figured it should be easy enough for me to configure a subdomain on my own server that forwards traffic to another port that I could open when I need to.

RiveScript's Original Niche

I wrote this article for the RiveScript Community Wiki, but am reposting it here for visibility.

I've been noticing more and more lately that people are using RiveScript to power Facebook Messenger chatbots, which adds a whole lot of complexity that RiveScript wasn't ready for. This article explains why RiveScript was designed the way that it is, what it's doing to support modern chatbots, and recommendations for how to design a modern chatbot.
