Should I use 'has_key()' or 'in' on Python dicts?
...ng, I didn't see that. I suppose it's because x in d.keys() must construct and destroy a temporary object, complete with the memory allocation that entails, where x in d.keys() is just doing an arithmetic operation (computing the hash) and doing a lookup. Note that d.keys() is only about 10 times as...
Is REST DELETE really idempotent?
...quests is the same as for a single
request. The methods GET, HEAD, PUT
and DELETE share this property. Also,
the methods OPTIONS and TRACE SHOULD
NOT have side effects, and so are
inherently idempotent. "

Occurrences of substring in a string
...at this might or might not return the result expected. With substring "aa" and string to search "aaa" the number of occurences expected may be one (returned by this code), but may be two as well (in this case you'll need "lastIndex++" instead of "lastIndex += findStr.length()") depending on what you...
Why does the CheckBoxFor render an additional input tag, and how can I get the value using the FormC

This isn't a bug, and is in fact the same approach that both Ruby on
Rails and MonoRail use.
When you submit a form with a checkbox, the value is only posted if
the checkbox is checked. So, if you leave the checkbox unchecked then

How can one change the timestamp of an old commit in Git?
...
Use git filter-branch with an env filter that sets GIT_AUTHOR_DATE and GIT_COMMITTER_DATE for the specific hash of the commit you're looking to fix.

But you can create your own sub-class of multiprocesing.pool.Pool (multiproc...
Why not use HTTPS for everything?
If I was setting up a server, and had the SSL certificate(s), why wouldn't I use HTTPS for the entire site instead of just for purchases/logins? I would think it would make more sense just to encrypt the entire site, and protect the user entirely. It would prevent problems such as deciding what has ...
Is there a simple way to remove multiple spaces in a string?
