Finding an optimal solution is much more computationally intensive than verifying that the solution is good enough (no collisions). If you don't really trust the RNN's work, then you can use a second algorithm just to check for co

Do you have a good description of hstore 2? A google search found a few references that there is an hstore 2, and that it might be related to PG 9.4, and that it might allow the values to be non-string, and it might allow nesting... nothing

Compared with adding multiple rows to a table to simulate one local variable? I expect readability and performance will both be greatly improved, but... it's hard to offer a good recommendation without knowing what sort of calculation

The extension you want is hstore. It allows you to create variables and columns of type hstore which is a (String -> String) hashmap. If you actually needed something more like (String -> Integer) or (String -> Decimal), then you&#

It varies by course, so you'll need to look through the catalog. The prices are monthly, and all courses are "at your own pace", but they give an estimate for each course of how long the course will take. https://w

Mostly true. (They won't deny EVERYTHING because that wouldn't be believable.) If this argument is made convincingly in Congress, the NSA could lose funding, but that's a hard decision to make. Even if I am opposed to individ

This latest leak reduces the NSA's effectiveness at whatever they are doing. That is a good thing if, and only if, the NSA does more harm than good. It tells us nothing about whether the NSA does more harm than good. That is the key po

Whether it is acceptable for the NSA to eavesdrop on private messages should not depend on whether those messages are protected by encryption. If I send an unencrypted email to a friend, is the NSA allowed to eavesdrop and get a copy of tha

It sounds like you're misunderstanding Kevin Drum's statement. The sentences that you quoted are examples of leaks that Kevin Drum believes were in the public interest. Kevin supports these leaks because they are about what the NS

The mucky mucks can have their answer today with a random subset of that data: 10,000 accounts and the corresponding addresses and transactions. We'll need map-reduce tomorrow if they want precision in the last decimal point.

The MIT article was submitted earlier. The Rice submission even emphasizes that by ending with "too". So by the time I scroll down far enough to see the Sal@Rice article I am thinking, yeah I already know he's giving a commencement address

"what it means to be a string includes styling (bold, italic, etc.)" I would keep String and StyledString separate. Lifting to a StyledString is okay if you want to concatenate a String and a StyledString. (plain "This is ") ++ (bold "GREAT

This surprised me: link has type (String -> String -> String), taking URL and label as arguments, and returning HTML code as a string (instead of as an Element). Then you need to use the text function (String -> Element) to make

The instructor emphasized the performance benefit of Octave's optimized matrix operations. Did you use Colt's matrix operations, or were you able to match the performance of vectorized Octave code with non-vectorized Clojure code?

It probably helps a lot that free apps are unloaded when idle, then reloaded on demand when someone is actually making a request. Ideally, the cost could approach the disk space of 30k small git repositories. http://stackoverflow.com/quest

Excellent news! Heroku is the only reason I gave Ruby/Sinatra a try for a while. I love the idea of having Heroku-style deployment without giving up Clojure.

I would have considered this a bargain when I was doing a lot of Clojure programming. (I recently switched to Common Lisp for my first full-time Lisp job at MCNA.) I'm very curious to see how/whether you include outside libraries later.

It seems that the inventor of object-oriented programming was one of those skeptics. Alan Kay apologized for his poor choice of words, for the resulting confusion, and for the widespread misapplication of his ideas. http://bexhuff.com/2007
