Change src image on hover (without white flash)

The following CSS and HTML will change a src image on hover, without any white flash effect from the next image loading. It does this by loading both images, setting the position to relative so they sit on top of each other, and configuring the z-index to control which image is visible.

// CSS

.product-photo-hover {
  display:block;
 position:relative

Why classes are cooool!!11

• In my app I have a lot of objects that represent an album.
• Until recently, I was using a generic hash for what I needed
• eg.

album = {
  album_name: "Pure Heroine (Deluxe)",
  artist_name: "Lorde",

# If Alice tosses a coin until she sees a head followed by a tail, and Bob tosses a 
# coin until he sees two heads in a row, then on average, Alice will require four tosses 
# while Bob will require six tosses (try this at home!), even though head-tail and head-head 
# have an equal chance of appearing after two coin tosses.

List of Google Analytics referral exclusions for payment gateways & 3D secure domains

You want to add these domains to Analytic's Referral Exclusion List, otherwise your Acquisition and Ecommerce data will be associated to these domain rather than AdWords, Organic etc.

This list is very incomplete and heavily biased towards the United Kingdom. If you're in the UK this probably covers enough to reasonably consider the problem solved.

TODO: Find a better way that doesn't rely on having to add every bank's own 3D secure domain... (possible solution - investigate Fix2 Actually, this looks like the bees knees)

Principles, Concepts, and Mental Models

A living list of mental models, biases and other interesting things that help improve how I think.

Decision making & prioritisation

• Not invented here syndrome: Reinventing the wheel rather than finding and using a pre-existing external solution.
• YAGNI (You Aren't Going to Need It): Don't waste resources building presumptive features now (because they may never be needed, even if you think they will).
• Premature optimisation: A type of YAGNI. Don't optimise before you need to. You might waste an extra week on optimisation that is never needed.
• Bikeshedding (Parkinson’s Law of Triviality): a committee whose job is to approve plans for a nuclear power plant may spend the majority of its time on relatively unimportant but easy-to-grasp issues, such as what materials to use
