You know how some people wear a tiny purse and carry a larger handbag / briefcase?
I usually carry one large tote bag (magicbag [*]).
Today, I realized that I was tired of larger items (laptop, gym clothes) in magicbag crushing or eating the other items (phone, wallet, sunglasses).
And I realized —
I needed L1 cache.
[*] magicbag is magic because it is of many colors, and at least one of them is bound to match my outfit. The alternative is to have a neutral-colored bag, but then you’re in danger of looking like you’re perpetually stage crew of some production (a my coat is black too).
[**] magicbag is always Le Sportsac, which i like because it can carry a lot, but has little mass on its own. The tradeoff is that there’s not a ton of structure, and things like sunglasses get eaten (groping through the entire bag is O(n)). Compare to a highly structured leather bag, which weights 1lb on its own but gives O(1) access to your junk.
