PDF wrapper for FileOptimizer (Python)

2016-10-29T20:22:27-07:00

Python recipe 580711 by Harald Lieder (fileoptimizer, fitz, mupdf, optimization, pdf, pymupdf).

Among dozens of other filetypes, FileOptimizer also compresses PDFs - often significantly. The issue is that the used plugin smpdf is free for non-commercial use only and it annoyingly also overwrites metadata information to state this.

The following tool remedies these metadata changes (but not the license situation!).

lru_timestamp - cache entry aging for functools.lru_cache (Python)

2014-02-02T21:28:25-08:00

Python recipe 578817 by Peter Santoro (age, lru_cache).

Return a timestamp string for @lru_cache decorated functions.

The returned timestamp is used as the value of an extra parameter to @lru_cache decorated functions, allowing for more control over how often cache entries are refreshed. The lru_timestamp function should be called with the same refresh_interval value for a given @lru_cache decorated function. The returned timestamp is for the benefit of the @lru_cache decorator and is normally not used by the decorated function.

Positional arguments: refresh_interval -- in minutes (default 60), values less than 1 are coerced to 1, values more than 1440 are coerced to 1440
