jaredtobin··on Ravens OL John Urschel, 26, retires abruptly, two days after CTE study
It's not that hard to believe. Here [1] is a somewhat e-famous example of a three-person family whose annual spending is around ~$25k.

jaredtobin··on Don't use Hadoop when your data isn't that big (2013)
Just conjecture, but I imagine that he got tired of the mods accusing him of trolling (in his uniformly high-quality and civil commentary) due to his non-standard political views.
jaredtobin··on Why recursive data structures?
It's exactly a hylomorphism. Here's a possibly more familiar-looking Haskell form:

    {-# LANGUAGE DeriveFunctor #-}
    {-# LANGUAGE LambdaCase #-}

    import Data.Functor.Foldable
    import Data.List.Split

    data QuadTreeF a r =
        NodeF r r r r
      | LeafF a
      | EmptyF
      deriving Functor

    builder :: [a] -> QuadTreeF a [a]
    builder = \case
      []  -> EmptyF
      [x] -> LeafF x
      xs  -> NodeF a b c d where
        [a, b, c, d] = chunksOf (length xs `div` 4) xs

    consumer :: QuadTreeF a [a] -> [a]
    consumer = \case
      EmptyF            -> []
      LeafF a           -> [a]
      NodeF ul ur lr ll -> concat [ll, ul, ur, lr]

    rotate :: [a] -> [a]
    rotate = hylo consumer builder
jaredtobin··on New Zealand earthquake: Tsunami follows powerful tremor
We even felt it up in Auckland. It woke my partner and I up and made the building creak and flex a bit.
jaredtobin··on People get “violently ill” from Soylent bars
Discussions on this kind of thing probably largely settle into opposing "yay Soylent!" and "boo Soylent!" sides. When I look at this as a tidbit of news, however, it doesn't seem to say very much to me.

"Small percentage of consumers report dissatisfaction with product - company investigating."

jaredtobin··on The DAO close to $100m in funding. Soon to be the largest crowdfunding ever
The code that defines the contract is publicly viewable on the blockchain. [1]

jaredtobin··on The DAO close to $100m in funding. Soon to be the largest crowdfunding ever
I contributed, and I know what I know by virtue of playing with the technology, keeping up with the news in r/ethereum, etc. The usual kind of thing one does in smaller tech communities.
