Privacy Policy

Who we are

I am the random dude on the internet who owns this blog.

What personal data we collect and why we collect it


When visitors leave comments on the site we collect the data shown in the comments form, the visitor’s IP address and the browser user agent string to help spam avoidance, a huge problem: over the 15+ year lifetime of this blog, most (>98%) comments were spam.

An anonymized hash created from your email address may be provided to the Gravatar service to see if you are using it. If your comment is approved, your profile picture is visible to the public in the context of your comment.. The Gravatar service privacy policy is available here:


If you leave a comment on our site you may opt-in to saving your name, email address and website in cookies stored on your local machine. These are for your convenience so that you do not have to fill in your details again when you leave another comment. These cookies will last for one year.

Embedded content from other websites

Most of the images on this site are my own. However, embedded content (e.g. videos, images, articles, etc.) from other websites behaves in the exact same way as if the visitor has visited the other website.

These websites may collect data about you, use cookies, embed additional third-party tracking, and monitor your interaction with that embedded content, including tracking your interaction with the embedded content if you have an account and are logged in to that website.

That’s just the way the Internet works.

I would recommend using ad blocking software (I am currently favoring UBlock Origin). If you’re computer savvy, NoScript is good.

Additional steps I recommend to my family and friends:

  • Use a browser that has adequate security safeguards. As of late 2019, this includes Vivaldi, Microsoft Edge and Mozilla Firefox. Chrome and Safari probably okay for most people. Internet Explorer should be avoided.
  • Disable Shockwave, Flash and Java.
  • Disable third-party cookies. This may break some sites.
  • Use ad- and social media blocking plugins. uBlock Origin, Ghostery and Disconnect seem to be pretty good.
  • Periodically purge your entire browser cache. You will trade convenience and speed for privacy.
  • Do not load images from emails by default.
  • Use a password manager. Never, ever reuse passwords.
  • Don’t use Facebook.


I’m a data scientist, so I’m always collecting and analyzing anonymous data.

Who we share your data with

Except for the examples cited, we are unaware of any additional sharing.

How long we retain your data

If you leave a comment, the comment and its metadata are retained forever so we can recognize and approve any follow-up comments automatically instead of holding them in a moderation queue.

Occasionally, I will respond to your comment.

What rights you have over your data

Not a lot, unfortunately.

Where we send your data

Visitor comments are checked through Wordfence and Akismet, because spam is a huge problem. Email is hashed with gravatar for the icon displayed next to comments.

Additional information

What data breach procedures we have in place

None. Assume everything you enter here will eventually be made public.

What third parties we receive data from

Gravatar creates an icon based on a hash of your email.

WordFence and Akismet attempt to determine if you’re a spammer based on browsing metadata and patterns.
