Comment on Django annoyances: no reverse select_related by Bas Westerbaan

Yeah, that is what I was thinking about. However, it’s still a waste to have to fetch all comments, when possibly only displaying 30 of them. (You changed the direction of the reference in your code).

You can work around it using select_related to retrieve comments to the pages, and then combine them in the python code using groupby.

from django.utils.itercompat import groupby

comments = Comment.objects.filter(**kwargs).select_related(’page’)
pages_with_comments = dict(groupby(comments, lambda t: t.page))

Its something thats been bugging me for quite some time, and just lately its become quite a nusance. If django gracefully degraded and gave you appropriate manual controls for this exact sort of thing it wouldn’t be so bad. But I can’t seem to work that bit out quite yet.

Thanks for this code snippet. On my device a don’t have urllib, thus your approach saved my day

import urllib
urlencode = lambda s: urllib.urlencode({’x': s})[2:]
assert urlencode(”foo bar baz”) == “foo+bar+baz”

Map-reduce. Not exactly a replacement, but hey, it’s fun.

You know, the thing about SQL is, that there is virtually nothing that can replace it.

Does anyone know if a substitute exists for sql? I mean besides MS SQL and Oracle and all that jazz. Thanks.

If you document stupidity, it’s still stupidity.

Do read the documentation. Month is a zero based index.

Comment on Negative .Net myths busted by Bas Westerbaan

This blog is since long old and dead but I thought Iâthrow in my few cents for the late night browsing guys.

The comments are still coming in at a steady (slow, but steady nevertheless) rate .

C++ is still there for those mission critical heuyes space shuttle PICs (if you’d even use C++ for that).

I personally wouldn’t use C++ for a space shuttle — the behaviour of the language is way more complex. Having pointers makes a proof of correctness hell. MsIL on the other hand, is a lot more amenable. Pure functional languages even more, if you are into them .

I agree with you. C# is the right tool in a lot of cases. Personally, I like my language even more extreme. Almost everything I write, now, I write in Python. It’s slow, sure. However, the volume of third party libraries is great; the language itself cooperative and when I do want performance, I write a module in C. Yet I have to agree that Python will never be the Lingua Franca, which Java is and C# will become — it is a lot easier to write ugly code in Python, whereas in C# you are forced to think a bit.

C# has evolved alot since 2005-2006. I can’t say I’ve ever laid eyes on a cleaner and more productive language.

What do you think about Python, Ruby, D, Scala and Clean? I still think C# is a great language, though.
