alt Hacker NewsThis string manipulation stuff is very common, and that's why in 2026, an age where science fiction has become a reality, many things are still absurdly slow. Exactly because of such sloppiness, which does accumulate in many cases, and when one least expected it.
100% agreed on the sloppiness. But overflow checking is not sloppiness. It's the opposite of sloppiness. Unchecked math is sloppiness, allowing overflows to happen silently and uncontrollably is sloppiness. It just so happens this kind of sloppiness makes code faster, unlike other kinds of sloppines that make code slower. Not doing necessary safety checks is faster than doing these necessary checks, but it doesn't make these checks any less necessary. Not validating user input also makes code faster, and is also sloppy.
