How to create a trie in Python
... may take up to 50x-100x less memory than
in a standard Python dict; the raw lookup speed is comparable; trie
also provides fast advanced methods like prefix search.
Based on marisa-trie C++ library.
Here's a blog post from a company using marisa trie successfully:

For 2.x, "file-like object" is too vague a thing to check for, but the documentation for whatever function(s) you're dealing with will hopefully tell you what they actually need; ...

This means that somehow, somewhere, connect resets the limit paramete...
Rolling or sliding window iterator?
...ables and small windows. On larger windows, the deque pulls ahead again in raw speed.
Access to individual items in the deque may be faster or slower than with lists or tuples. (Items near the beginning are faster, or items near the end if you use a negative index.) I put a sum(w) in the body of my...
Formatting code snippets for blogging on Blogger [closed]
...blog. SyntaxHighlighter is very easy to use. It lets you post snippets in raw form and then wrap them in pre blocks like:

Some "raw" type file formats might just be a stream of bytes with some "end of line" byte at the end of each horizontal row of pixels (in which case the software must read the first line and divide the size of the byte stream by th...
What type of hash does WordPress use?

Your hex value would be sZRqySSS0jR8YjW00mERhA== in Base64, which uses 25% less characters than hex to represent the s...
