Note for Python detractors...

If you post a public diatribe against Python - which is your right, go ahead and express yourself - but your centerpiece is "Python is slow!", you're marking yourself out as (a) not knowing Python very well, and (b) hating it because you don't understand it.

It's the more modern cousin to "Python sucks because I can't (not) indent to my taste! Significant whitespace, yuck!". It makes it very difficult to take any of the rest of your complaint seriously.

(Significant whitespace has been shown to result in less opportunity for confusion when reading code, and you spend a lot more time reading code than you do writing it.)

And while Python may be slower for some tasks compared to some other languages, it's (a) not outrageously slow, and (b) a case of use the right tool for the job. I can't trim my lawn quickly at all with my pinking shears, but that doesn't mean pinking shears are "slow".

So please, write your analysis - but make it deeper than "argh it sux i hate it i hate it" if you want anyone to actually consider your argument.

Command-line Tools can be 235x Faster than your Hadoop Cluster
"This find | xargs mawk | mawk pipeline gets us down to a runtime of about 12 seconds, or about 270MB/sec, which is around 235 times faster than the Hadoop implementation."

Hard Moving on From Perl When It Keeps Being More Good Enough Than the Other Good Enough Solutions

That's reductionist (and apparently passive-agressive as well?) The high-friction nature of blog comments, plus the long-delay-refresh and unpredictable lag make it a poor medium for back-and0forth conversation. #RightToolForTheRightJob
