To add to this, the schema.rb or structure.sql files rails makes are never 'accurate'. By which I mean, they simply record the state of the database at the time of the last migration. If you are switching between branches, for ins

If you've ever bought bandwidth at a colo you know the AWS rates have extremely high margins. I'd wager that DO can afford it, it just eats at their margins.

Recall that PUT / DELETE aren’t official HTTP requests, rather extensions implemented via WebDav. Modern applications don’t bother with these requests since its easier / more secure to perform those same actions with a server sid

Interesting, I'm looking at it right now, and it's saying that the multiple regexes are ~ 50% slower in both chrome and firefox. Am I missing something? It looks like the single regex actually is a significant win. It is interesti

You are 100% correct, I forgot about that extra group (that doesn't need to be there). That being said, most frameworks don't have multiple matching routes, and I can't imagine that many people miss them. I've never used

by andrewvc 12y ago
Ah, I did miss that, but it does still work. Run the following code below, you'll see multiple groups match. "/foo/bar/3".match(/((^\/foo\/bar\/.*)|(^\/foo\/bar\/(\d+)$)

by andrewvc 12y ago
You're right that it's O(n), but it's still faster than express js. It's not iterating through the array that's slow, its evaluating the members of that array. Express must check each route using JS functions that e

First off, you don't need to handle the 'multiple' case, since the "|" has precedence rules applied to it. The leftmost match is the match. Second, you know which one matched based on the index of the capture groups
249.
by andrewvc 12y ago
What I'm saying is that the pipe (or) "|" is a cheap way to combine regexps. It has its limitations, but its better than an O(n) search through an array. The regexp parser can create an NFA that is far more optimized.

by andrewvc 12y ago
A lot of people here are right, the right way is with an NFA. I just want to add that the solution is not even hard, you can do it with string concatenation and capture groups using regexps. Regexps are NFAs, and are highly optimized C code

We were in a similar spot. Our startup is building a relatively large flux app. We interviewed Ian Obermiller of FB on a lot of the concerns of a large app. You can find a lot of answers to tough questions in our transcript: http:/&#x

Why are they demoing this 'ergonomic' desk, with such an unergonomic monitor configuration? If you don't raise the monitor up, and keep the keyboard level down to keep the right angles you'll be asking for pain. The poin

I think the thing you might not be aware of is that your posts are attempting to sidestep real issues. Instead of focusing the discussion around acknowledging and preventing abuse and discrimination, you're quibbling over whether women

So you're seriously equating getting an unwanted job offer with a threat of sexual violence? What?

What I urge people in this thread to do is not to pick up a google search, or read a book, but to just go out and ask a few female friends what their thoughts are about being online, being safe, and being respected, and to listen with an op

You're right, you didn't 'quote' them. You merely summarized the articles inaccurately in order to make a point. I think that's actually far worse. It seems that you're intent on quibbling semantics, selectivel

You're really selectively quoting those studies. From the first link (the pew poll): Young women, those 18-24, experience certain severe types of harassment at disproportionately high levels: 26% of these young women have been stalked

One thing this is leaving out is that IBM existed, and was very successful, long before mainframes. The company has existed since the 1880s for christ's sake. Additionally, during the mainframe era it had a number of other successful p

Well, react/flux completely replaces backbone except for the router. The models go away completely, as do the views.

I'm actually using 'director' which works great, much simpler.

What, no React/Flux? How can this be a serious comparison without React?

Totally agree! FWIW, I'm betting on Hindley-Milner in the long run. The thing is, is it as important as something like library availability, good docs, etc.? Often times the answer is no.

And herein lies the issue. As engineers we long to solve 'special' problems, and fool ourselves into thinking we need to do something novel and hard when something simple will do. We fool ourselves into thinking we NEED a faster l
