Double indentation looks rather ugly though. I like the "K&R" style much better (as shown in comment from bpicolo): def some_descriptive_function_name( one_parameter, another_parameter, ): som

Looking at the examples from the official documentation, I agree with your sentiment. Indeed, the conciseness can cause some confusion to people familiar with the existing scoping rules. IMHO, it's a good thing if LATERAL is only added

I feel rather underwhelmed by the performance improvement touted by adequate records. Perhaps someone from the rails community can do something like this: http://techspot.zzzeek.org/2010/12/12/a-tale-of-three-

So, with T2 instances and General Purpose volumes, Amazon is now officially in the overselling business. Kudos to them for finding a way to do it fairly. Looks like extra tough time ahead for lowendbox sellers.

The jmespath library from boto is quite similar to this, and possibly has way more traction. Some differences: - jmespath uses `body.translations[0].language` instead of `body.translations.0.language`, and it can also do `body.translations[

This is not strictly about Ruby vs Python. Having used Pyramid (+SQLAlchemy) and Rails, I think the former is plenty fast enough such that no user cares about silly optimization, while the latter is the opposite. Loading the Rails environme

In my opinion, the full explanation is too long to be put as code comment, but is just right as the commit message. The best way is to keep the commit message, but add a short comment like: // Hack to trigger layout change i

Good article, but I think it touches too little about persistence. The trade-off of EBS vs ephemeral storage, for example, is not mentioned at all. Getting your application server up and running is the easiest part in operation, whether you

With SQLAlchemy, I have done similar optimizations against mssql by changing a few lines of ORM code. Without SQLAlchemy, I imagine I'd have to change dozens of hand written SQL queries. A good ORM helps you to generate the exact SQL y

I am pretty sure SQLAlchemy will translate that into: UPDATE purchase SET downloads_left=%(downloads_left)s WHERE purchase.id = %(purchases_id)s; By the way, the posted code has an off-by-one error, as it should do the checking fir

Sriracha made its debut in Malaysia approximately a month ago, being sold for MYR 21.90 (28 oz) and MYR 13.90 (17 oz) by Ben's Independent Grocer in Solaris Dutamas. Pretty nice profit margin there, now that the wholesale price is no l

I like your comparison of SQL to JavaScript. However, personally I love SQL and always use an ORM. My vow is to never have a line of SQL in my application source code. This is perfectly doable with SQLAlchemy, though not with crappy ORM s

Perhaps a more advanced camera technology that detects asshole driving behavior instead of speeding? Rich dudes pay to get ahead. Increased revenue for the police department. Improved traffic. Win-win for everyone.

The gist I get from the link is that the act of "smoothing the wave" will not benefit the one who performs the act, but it benefits the drivers behind the lane. You can't fix the traffic jam in front of you, but you can do yo
