Use cases

• Optional/nullable data types.
• Variant data types.
• Flag with extra information needed only in some cases (or different in different cases).
• Modeling states in a state machine where each state can have some data associated with it.
• List of operations for batch processing, where each operation can have its own arguments.
• Alternative to function overloading that allows avoiding combinatorial explosion when there are multiple parameters that need variants.
• Nested data structures with heterogenous nodes.

Falsehoods that Ethereum programmers believe

I recently stumbled upon Falsehoods programmers believe about time zones, which got a good laugh out of me. It reminded me of other great lists of falsehoods, such as about names or time, and made me look for an equivalent for Ethereum. Having found none, here is my humble contribution to this set.

About Gas

Calling estimateGas will return the gas required by my transaction

Calling estimateGas will return the gas that your transaction would require if it were mined now. The current state of the chain may be very different to the state in which your tx will get mined. So when your tx i

Optimization in the Source Engine is a critical component of mapping that not only makes your map compile faster but run better in game. However the two results are not always related.

"Why does it take so long for my map to compile?" The short answer is Source uses an optimization method called Binary Space Partitioning. The way this works is by cutting your map up into sections called leaves based on your brushes and then calculating what is in each leaf and then what leaves each leaf can see.

If you want a really good easy to follow explanation watch this video and this video

For optimizing in Source follow these in order and by the end you should have a fairly good understanding of how to optimize your map for performance and compile time. This is something you are going to have to practice
