From what I understand, it creates a new table with the same structure as the existing table, runs your migrations on it, adds triggers to bring live changes in from the original table while copying (in batches) the records in the old table

For ActiveRecord (or other Ruby-based) migrations with MySQL, I've had good luck with Large Hadron Migrator[1]. It's worked flawlessly for some of our own tables with several hundred million rows (and no downtime). [1] https:&#x2

Parse's solution is a great start as you say, but I can see myself running into the limits of that approach fairly quickly. And, as you say, if these solutions mature, we might have some very powerful stuff in this space in a few years

From the video: > Building the backend... is a lot of work. You have to build it, deploy it, and manage the infrastructure that it runs on." To me, it certainly sounds like they're trying to market this as an alternative to hav

Why do so many people (and companies) pretend that app backends are just (logic-less) data stores? I can definitely see the argument that some mobile games only need to store/sync some basic state information on behalf of the user, but

Not surprisingly, most of the results for common words/phrases seem to be unavailable. For a simple domain search, that's expected, but not so much for a suggestion tool. If I'm going to wait for a small handful of domain sug

As a longtime fan of Thin, I've been very impressed lately by Reel[1], which is built on Celluloid::IO. In particular, Webmachine-ruby[2] is a nice framework that supports Reel. While arguably not popular enough (yet) to be considered

I recommend Dokku ( https://github.com/progrium/dokku ) if you want something similar to Heroku. The nice thing about Dokku is that it's simple without locking you in to any particular (proprietary) cloud provider s

Sounds like the core problem is just "Chinese web sites have yet to take full advantage". I'm really wondering how many (or what percentage of) devices actually need "a special plug-in". Seems like it would be a ver

Interesting. From what I can tell though, the lack of support from those TLDs seems to be deliberate rather than due to any technical challenge (the domain you register ends up just looking like standard alphanumeric ASCII with some dashes)

I'm surprised there's no mention here of punycode and IDNs. Is there just not enough widespread support for IDNs (the article mentions a need for plugins, but I thought most browsers already support IDNs), or are numbers really th

It's easy (or easier) to call your own app "stupid" when it's a single-person effort. As soon as you bring on other people to help, it's hard to call it "stupid" - not because the app changed and not becau

I agree. The fact that a large number of Ruby/Rails apps fall behind in terms of keeping dependencies up-to-date speaks more to Ruby's adoption than to its inherent insecurity. Without comparing these figures to other languages&#x

I love the idea of FPCs, but I have a hard time understanding the practical applications. Even the Wikipedia entry[1] seems to list examples, most of which don't entirely rely on the flexibility of the device. I can understand the need

True. This may just be due to inaccuracies in the depth map. And therein lies the problem with synthetic aperture algorithms like this: to make it look (close to) natural, you need very clean depth boundaries. There will always be problems&

I believe the algorithm could be improved by applying the blur to certain areas/depths of the image without including pixels from very distant depths, and instead blurring/feathering edges with an alpha channel over those distan

That's true. Still doesn't mean you should optimize for CTR when you're really interested in conversions. But I do see your point that in some cases - especially when starting a new campaign on a tight budget, it would be use

Again, if you've set up your campaign to optimize for what you really want to see (not just clicks), then why would you even need to care about desktop vs tablets? There are more and more devices every day that blur the line between de

So don't optimize your campaigns simply for clicks. A lot of people here are complaining that Google is doing something "shady" by making ads available to mobile platforms (mobile ads are here to stay regardless of how people

It's been a little while since I've used it, but doesn't Google let you do placement optimization based on meaningful conversions or other user-defined goals? It sounds like the problem here was just Google's ad placemen
