I mostly contributed in [java] and [regex] from February to August of 2010. I work for Palantir Technologies now, so I may not have much time on stackoverflow as I did then.

We're currently hiring; you can e-mail me for a referral.

A few habits I've developed on the site:

I will no longer cast a downvote. It will stay at 54 forever.
I don't like to engage in dramas on stackoverflow. If you really need to discuss politics and other non-technical issues with me, bring it to meta.
I delete my comments once they've become obsolete
I try to revise my answers periodically, so I prefer that you leave comments and feedbacks instead of editing my answers directly.

Jul 17	comment	What are the pros and cons of having a CaseInsensitiveString type in Java? I don't buy this "depends on the context" pov. You can say that there's no point of using generics for type safety by declaring a `List<String>` or a `List<Integer>`, because the type of objects that the list contains depends on how you use it, and not the property of the list itself (which of course, is not a very defensible claim). Besides, arguing that it depends on the context actually makes the case stronger for making this property intrinsic and invariant of the type, because it's so much simpler precisely when you DON'T care about the context.
Jul 6	comment	What are the pros and cons of having a CaseInsensitiveString type in Java? So would you recommend a `TreeSet<String>` using `String.CASE_INSENSITIVE_ORDER` over a `HashSet<CaseInsensitiveString>`? Note that using `TreeSet` means `O(log n)` for `contains`. Moreover, this comparator is inconsistent with `equals`, meaning that the resulting `TreeSet` doesn't obey the general `Set` contract (i.e. it may `contains(x)`, even though it has no element that is `equals` to `x`).
