A set of tasks to do in a programming language to ensure you understand how to do the basics.

Each task involves writing some basic code e.g. write to a file. Build it with the appropriate tool, unit test it, bechmark it and strace it to see what it is doing unde rthe covers.

Both asynchronous and synchronous IO:

• Copy a file
• Read whole file into memory
• Random access in a file
• Sequential access
• Stream a file without bring it all into memory

Both asynchronous and synchronousi for both server and client:

• Transfer a large amount as quickly as possible (Throughput)
• Transfer a small amount in the shortest time (Latency)

• Benchmark operations on primitive types if they exist
• Build a binary calculator
• Profile the above
• Build a B-Tree and profile

• Use classes, structs, records, discriminated units etc to model a portfolio management domain
