Closer to work where most jobs are. Less commutes? I noticed young people love to be in the busy and noisy cities.
I'm not really sure what you mean by "parsing" in this instance, but a decoder is free to skip over irrelevant chunks (real name for them) in a PNG file and access only the chunks it needs (header, palette, image data, etc.).
No they shouldn't. Creating a *policy* of stripping metadata and enforce it through code audits. Embedding resources (or not) into a file is a developer decision, not a compiler decision. The compiler has no way of knowing which bytes of the resource you embed are important and which are not, be they strings, PNGs, or anything else.
The amount of time between slipping on the peel and landing on the pavement is precisely 1 bananosecond.
