While I agree with the author that feature branches are useful, I think he went too strongly the other way, against feature toggles. Feature toggles allow you to do things like: 1) deploy only to certain users. 2) incrementally deploy to N

Stupid question: Why was this not caught? Seems pretty easy to test. Just set the clock to today (or any day with a leap second), and watch what happens.

N+?? The time library in your programming language is correct. Every time library I've ever dealt with will have serious problems with at least one issue listed on the original article or in the comments here. JodaTime (on the JVM) is by fa

After I wrote this last night, I'm now leaning towards the idea that the "rare item" economy is intentional, and working as designed. In effect, by making it difficult to turn virtual gold into money, and allowing rare items to sell on EBay

Yes, you're absolutely right. However, Netflix is distributed across multiple AZ, while Heroku has spent the last two years after their $212MM acquisition in the same AZ. That makes it sound like Netflix has a more reliable platform than th

Valve's games put a cap on real prices by selling the items through Valve's store. You can buy a new gun for $2, so the price of the gun in "ebay gold" will never rise above $2. (Big simplification for TF2 players follows) Also, in TeamFort

I've found or read about bugs in nearly every stdlib time library I've ever worked in, except Joda time[1]. If you rolled your own, you should worry more , but you should still think about it even if you didn't roll your own. [1] Joda is a

JRuby is still going to be slower than clojure, due to the semantics of ruby. All function calls are resolved at runtime, while clojure resolves as many as possible at compile time. Foo::Bar.method() vs (foo.bar/method) The ruby version doe

I get the feeling PT isn't a big believer in global warming, but the accepted term for those kinds of investments is "cleantech". If he called it "CO2-reducing technology investments", he'd sound like a curmudgeon who's more interested in b

There are two different issues here. 1) A bad security vulnerability at GitHub. 2) Poor design in Rails that makes it easy to produce security vulnerabilities. Igor found 2, and got ignored by the Rails team. His frustration led him to publ
