I write a lot of scripts that I run once or infrequently that uses open-rui. Occasionally I run into a web site that times out or is unavailable for a period of time. My normal solution is to just rerun the script manually at a later time and the problem goes away. What I would like to start doing is rescuing the open() and retrying the open() after a delay. What would be the most idiomatic way to try opening a url say n times before giving up? Here is my crude code for trying twice:

Did you even read the article you replied to? I already wrote that I
*did* my own tests and they I *did not* see any statistically
significant difference in performance.

It's interesting that you use the word "think" here. So, apparently,
you have your (subconcious) doubts, too.

> There is a reason for this speed improvement, I let you search it.

Again, I would like to know. The *only* source I could find so far, is
a video from a BoF session with Jon Lam from maybe two years ago,
which goes something like this:

| Audience: What about 1.9 support?
| JL: Microsoft has commited to making IronRuby a *real* Ruby
|     Implementation that runs *real* Ruby code. Right now, *real* Ruby
|     code is written in Ruby 1.8. We would *love* to start with Ruby
|     1.9, because it has some semantic changes that make it much easier
|     to implement and much easier to implement *fast*. But we have to
|     stay with 1.8 for now.

[Don't hold me to the exact wording. This is all from memory, and it
was just a minor sidenote in a video I watched two years ago.]

This is pretty much the only source I could find which actually names
a *reason* for the claimed speed improvements. However, "some semantic
changes" isn't actually incredibly precise, after all, in a
programming language, pretty much *everything* is a "semantic change".

So, if you know the reason, please share it. Saying "I let you search
it" isn't exactly helpful. After all, I wouldn't have asked if I
hadn't searched first, that's Netiquette 101.

Unfortunately, this table doesn't show the execution environment of
the individual benchmark runs. The only way in which this table is
useful, is if the benchmark runs were tightly controlled. Otherwise
you get uncontrolled variables, and all your benchmark results mean
squat.

In statistics, this is called "controlling your variables", but Zed
Shaw said it much better: "If you want to measure shit, don't measure
other shit."

In other words, if you want to measure Ruby 1.9 vs. Ruby 1.8, measure
Ruby 1.9 vs. Ruby 1.8 and not Ruby 1.9 and YARV vs. Ruby 1.8 and MRI,
because that way you will never know whether the performance
difference came from Ruby 1.9, YARV or a combination of the two.

Like I wrote above: *if* you actually *did* properly control your
variables for these benchmarks, then, yes, they show indeed a
performance increase for Ruby 1.9. And in that case, you really should
publish these results, because, like I wrote earlier, there is nothing
like this out there, at the moment.
