Loops obviously have their place, no question, but you're going to find that assigning a List to a var, and then appending to it / re-assigning it is going to generate a ton of garbage, and in general will just be slow all around.

Here's a more functional version of complete_items, if you're interested. def complete_items(...) = bin.items.flatMap((item, v) => expectedSymbol(item).map(nonterminal => grammar.nextValue(document, item.orig

I still, still, still don't understand why Node hasn't done in-line server-side Javascript. Give it a snazzy name. Maybe.. "Livewire". http://www.datacraft.com/livewire.html

Hi Clifton-- Thanks for the reply. Very thoughtful. I have a couple of points. "What we'd hoped to accomplish, and fell short on in the end, was a way for developers with non-traditional backgrounds find gainful employment."

(This comment is going to have a lot of HR and Marketing bullshit terms-- I'd like to apologize for these in advance.) It's rarely a good thing to read about a company closing its doors, and I hope that you guys have more luck in

If map performance is really an issue for you, you should look into using the parallel collections. For maps with less than 10k entries, I'm unable to see any difference between the immutable/mutable and ju.HashMap collections. Fo

Wha? In practice, we have seen much much _less_ garbage created by our Scala code. The use of objects in Scala encourages static method creation, and there's so much boilerplate Java junk that your Scala code just doesn't need.

It's incredibly difficult to find good Scala developers today, no doubt. However, it is incredibly easy to find Java developers who are curious about expanding their skillset. Those are the guys and gals who I hire, simply because it&#

Yes-- but those native applications are using JSON as their data transport back to whatever servers.

Here's the funny thing. We have here a shining example of why Microsoft is becoming irrelevant. You're making the case that Windows ME sucked, Vista sucked, 7 was good, and 8 sucks. You're absolutely missing the bigger pictur

I'm conflicted; on one hand, obviously protecting against the HTML sent in an e-mail is a good idea. I seriously considered having all e-mail bodies run through https://code.google.com/p/owasp-java-html-sanitizer&#

Dev here. Thanks to everyone for the comments, suggestions, and support. MailDrop is one of those nights-and-weekends projects that came together as a bit of an experiment. Here's a few responses. The design at a wider width is, okay,

Doing that would absolutely wreck the economy. Like, black swan systemic failure wreck. The mortgage tax deduction provides a huge amount of what turns out to be disposable income for the middle and lower-middle class. Take that away, and t

I think Play, with well-written asynchronous code, could approach the Netty/Vert.x speed. In other words, I'd be willing to trade the ease-of-use of Play for the slight speed impairment vs. writing directly to Netty/Vert.x/etc.

There are a few problems with your Play code that are causing it to be unnecessarily slow. First-- what you're really testing here is the Jackson library. A majority of the cycles used in your application are being burned in that toJson cal

Even if "considerably less than 10 seconds" means 9 seconds, that means the B-class could keep up with a 1982 Ferrari Mondial. In city driving, nobody cares about 0-60 times.

Yes, it will work. There's no magic sauce about adding whichever ORM you want; just declare it as a dependency in your build file and you're ready to go.

Play uses Ebean on the Java side of the fence. Anorm is for Scala users. Here's how to do a query for a person in Anorm: SQL("select * from person where id = {id}").on("id" -> myAgeVariable).map(row => MyPersonObject(row[String]("na

Since June, when the presentation was created, Play has gone through a few big revisions. The primary method of accessing a database is Anorm (which, if you aren't a Hibernate fan, Anorm is a huge win) although you can also use Hibernate, o

Yes, that's true. But the letter of part 3 only talks about encrypting data at rest on your own systems; it mentions nothing about client systems. There's a huge discussion about whether or not the user's browser is within scope for PCI-- t

Congratulations on completely missing my point. You say that this could be yet another datapoint for the IRS to collect taxes with. The example you use has the number of Foursquare (and I'm sure Facebook) checkins within the statistical amo

OMFG Starbucks reported $3B in revenue this past quarter, but this store only has 10k checkins! Send in the G-Men, they must be laundering money! Come on, seriously.
