Add heavily verbose/redundant math equations that take up multiple lines with each operation saving to a new variable, then either decrease the number of variable declarations or condense/simplify the math occasionally. Repeat with each new function. Killing two metrics at once LOC and the removal of LOC for older functions. Guaranteed promotions. lol
For durability and smallest features, a metal unibody types that don’t have seams are great.
For performance, I opt to have an nvme SATA enclosure that is USB 3.1 capable. Copying 15 GB in a minute or 2 is so satisfying. Plus my god being able to easily change the nvme SATA drive on the fly if needed and it being able to go up to a few TB without loss of performance is just to good
For price, nothing beats free. Just don’t expect much more than what you get.
