  • I think delivery trucks are probably still the better option for most packages when they are properly utilized, which they obviously aren’t being if the statistics given are accurate. It’s mass transit for packages. The ineffecciencies probably just come from the overarching problem of there being too many cars on the road. Without that, it becomes a lot more efficient to transport hundreds of packages at once in one truck than have dozens of bikes carry the same load, especially over an entire city. Anything that does need to be delivered quickly should be done by bike, but with proper logistics, delivery trucks actually are more space efficient.





  • Depends on if you’re using lossless or lossy compression. Lossless compression will usually make it bigger, because it relies entirely on data being formatted so their are common patterns or elements that can be described with fewer parts. Like, an ok compression algorithm for a book written in English and stored as Unicode would be to convert it to ASCII and have a thing that will denote Unicode if there happens to be anything that can’t convert. An encrypted version of that book would look indestinguishable from random characters, so compressing it at that point would just put that Unicode denoter before every single character, making the book end up taking more space.



  • And the fact that it can grow data means you should really put a test to make sure that the compressed data is actually smaller… I once had something refuse to allow me to upload a file that was well below their 8Mb file limit while it was claiming it was above the limit, and I’m assuming it was because they were testing the size after compression and that file grew from 6Mb to above the limit.
