Better Dev Link

On a large enough project, you’ll eventually bump into code that you don’t understand. The only way to understand is by run and debug it.

How on earth would you make a useful program without using an if statement? Do you remember that heavily nested code you had to understand last week? Let’s look at the problem that if statements pose and pattern we can use to repalce if.

Bash is almost everywhere, together with Linux utilities make it shine when we want to wire thing together. But Bash is not a language where the correct way to do something is also the easiest. If there is anything like a driver’s license for safe bash coding, it must be rule zero of BashPitfalls: Always use quotes

Deprecating APIs seems easy — issue warning on old method call, suggest new usage. Then use sed to replac all :D. This works for simple method call. How can we make it better? Write Ruby code that re-write your Ruby code.

Dataviz is a library that helps to build and understand standard data structures with added visualizations developed by Graphviz. It’s supplemented with many examples to help you learn and visualize how data structures work.

There are about six major of memory models. Three derive from languages of the 1950s — COBOL, LISP, and FORTRAN — and the other three derive from the three historically important data storage systems: magnetic tape, Unix-style hierarchical filesystems, and relational databases.

Chrome display a dinosaur game when in offline mode. It’s similar to how a child learning to walk? Using Reinforcement Learning and Q-Learning and selenium to play the game.

Any migration has a higher risks than other code change, especilly network provider. This blog post layout a strategy to build out a test framework and use it as a way to assert the new system is good and strategy for cut-over.

We’re going to explore the problem space, generate multiple solutions for our design decisions, compare those solutions to understand the tradeoffs between them, and finally choose the right solution for our system.

Despite replacing all human heuristics, AlphaGoZero still uses tree search algorithms at its core. I hope to convince you that AlphaGoZero’s success is as much due to this algorithm as it is due to machine learning.
