Ruby and Rails projects are abundant on github, providing lots of example code.

This isn't what the article is talking about. The article is arguing that subjective, linear wine ranking is faulty, that preferences are not objective or static, that it's difficult to distinguish between similar wines and that identifying individual flavors and scents (eg, "lavender, roasted herbs") are tied to the taster's imagination.

If you can tell the difference between grapefruit juice and orange juice, you can tell the difference between a gabbiano, a monticello rioja and a generic merlot. They taste dramatically different and you can't give a merlot to someone who knows what chianti tastes like and have them believe it's a chianti. Different varietals have very distinct flavors.

And when it comes to quality, there is a much, much more significant difference between a poorly stored, very low-quality wine and a mainstream ~$10/bottle wine than there is between a $20/bottle wine and a $100/bottle wine. After all, a number of the pricer wines would be simply $20/bottle if it weren't for the ratings systems critiqued by the article.

Assuming that's even possible or realistic, which it often isn't in markets dominated by a single vendor. Supporting vendor lock-in, particularly as a developer, makes it harder for open alternatives to exist. It's common for a single vendor to dominate a market for years. The future of jumping to an open platform could simply never come to pass.

The Merb/Rails merge reveals some reasons why there aren't a lot of widely used Ruby frameworks, and I'd say it's mostly a large scale manifestation of DRY, combined with the maturity and wealth of features in the Rails codebase and the fact that most of the changes devs would like to see in Rails are already going into it.

I mentioned Ian Bicking's great talk at this year's PyCon elsewhere in these comments, but another thing he touched on was framework fanboyism, and how it's mainly the result of people being new to the framework and trying to convince themselves that it's the answer to everything. Whether it's Django or Rails or any other technology, excitement is good, but not when it becomes tribal and adversarial toward perceived competitors.

I don't know what could cause the slow-down off the top of my head. Are there slow helpers? Also, IIRC, iterating over a collection to render each partial is slower than using render :partial => @collection.

As a life-long Chicagoan I still find it incredibly strange that people believe Chicago is safe. It has a very high crime rate, double NYC in every category.

"Traditionally, in grades 7–9 mathematics comprises 2 school subjects, geometry and algebra that are taught in parallel (e.g., 2 hours per week for geometry, and 3 hours for algebra). In the senior school [16-17 years old], also two subjects are taught, geometry and algebra and elements of calculus. In grades 5 and 6 (and in primary school) we have a united course of mathematics."

For comparison, the US high school math curriculum (for students 14-18 years old) is generally algebra, geometry, precalculus/trigonometry and calculus, although students can still graduate with just algebra and geometry.

That said, I don't doubt that there is a cultural and educational emphasis on math in Russia.

Note also that according to the trends graph, djangoproject's visitors have also been steadily declining over the past year.

Really, HN should be above this inanity.

Combined with

"Ruby's too trendy"

There's that cognitive dissonance again.
