CPU speed and bus speed is finite on the machine you're running on. Using setTimeout to poll the results of some thread you've spawned to run a calculation is _worse_ performance than just blocking in the first place, because now when you t

Holy god. The post mentions "We evaluated a few different NoSQL solutions, but (...)". I couldn't even imagine having to _think_ about this sort of thing; CouchDB makes this an absolute no-brainer. I mean, the act of creating a document ass

Implementing Actors, and by extension the Observer pattern, is just so ridiculously easy in Scala. observers.foreach(o => o ! myEvent) ...and you're sending asynchronous events to each of the observers. With Akka, you can have those act

I utterly, completely, totally disagree with this post. May I cite: http://www.scala-lang.org/node/10714 Kids can learn Scala. It isn't "hard", any more so than the syntax of any language is "hard". It's just another syntax to represent t

Let this post be a warning to web entrepreneurs everywhere-- if you take shortcuts like this, your business will get burned at some point in the future. Every single thing you've just said is wrong. Every single thing. First -- "the chances

Can you please list out the applications you've created? I'd like to add them to my "never ever register on these sites" list. If you're only worrying about injection attacks "...after you gain some traction" or "...when it becomes an issue

The death of the newspaper industry has absolutely nothing to do with kids downloading pirated music or movies, and absolutely everything to do with the fact that it costs someone precisely $0 to post an ad on Craigslist or read _more_ _tim

This is fantastic. Google created a stylesheet like this once, a while ago, that was extremely lacking when it came to real-world actions and layout. This is incredible.

I hate to break this to you, but for any larger merchant, you're going to be SOL, for one basic reason: PCI compliance. Unless you spend a ridiculous amount of time and money researching and implementing things like key management, credit c

You blame the architect, who didn't adequately cook in automated test cases to catch data integrity bugs.

It's unenforceable. Check page 19 of "Programming the Logic Theory Machine", by Newell and Shaw, published in 1957, for prior art.

You don't need to worry about the versioning for a document that you never update. You can just blast the logfiles into the database and not worry about conflicts. Similarly, database compaction is really the biggest concern when you're upd

Absolutely it would be great for logging. Assuming that you don't need atomicity for your logs (eg, I want to see that log line reflect in my reports _right_ _now_) Couch is a perfect way to dump a huge amount of data really quickly. For r

I'm a little biased, being a pretty heavy CouchDB user, but it seems like Mongo is claiming that their auto-sharding is the defining reason to use Mongo. The forthcoming release of Couchbase 2.0 is going to have the same type of functionali

I would go so far as to "bypass" the spec of CouchDB -- at least for Pouch -- by doing a sort of auto-compaction, clearing out the database of the previous revision at storage time, and only storing the latest revision. This doesn't stop yo

The devil's advocate argument is that it isn't readily apparent that you're using the ages array until you look deep inside the loop. With the scala code, especially with the functional syntax, you know what elements you're working with rig

Actually, the functional alternative in scala is this: persons.filter(_.age >= 18).foreach(p => { (code here) }); That is way, way more readable, imho.

Yes, total and complete fail, after going through what seems like a pretty standard 2-driver use case. There's no sort of progress meter, so I don't know how long I have to wait, and after the N/A quotes there's still a spinner running, so

Coincidence? "Randi Zuckerberg to leave Facebook..." http://news.cnet.com/8301-1023_3-20087785-93/randi-zuckerber... I think someone likely said, "enough is enough" and forced her out.

I'm at the CouchConf -- the demo of UnQL was fantastic. The idea is that you shouldn't be locked into a NoSQL database, and that one language that would work across all NoSQL databases will grow the community. How each database manages thei

A solid legal argument for switching your MAC address, hiding a laptop in a closet, and deliberately concealing your face to try to avoid recognition? He isn't going to win that defense.
