Github keeps the refs for pull requests separate from branches and tags. For example, you can fetch pull request #123 into a local branch called pull-123 with: `git fetch origin refs/pull/123/head:pull-123`. When you…
Here's an entirely working example I just created: https://gist.github.com/benolee/ca49aaa9a0363c18904b
Thanks for this--I mentioned finagle to jcoglan on twitter yesterday after I read his blog post, and I don't think he was aware of the similarities. I actually didn't know about futures until I learned about scala and…
NoSQL also exists. Carlo Strozzi first used the term NoSQL in 1998 as a name for his open source relational database that did not offer a SQL interface. http://publications.lib.chalmers.se/records/fulltext/123839....
Even worse, he lists "brainfuck" as a technology that's easier to use outside of the big-company matrix. There is no such thing as "brainfuck". There are various dialects and derivative languages. There is the…
I randomly stumbled across this gist by tenderlove https://gist.github.com/tenderlove/4576780 that displays references as a tree view using d3.js. I think that this gist in particular is pointing out a bug in that the…
AFAIK, to use the brightbox packages on heroku you'd have to write a buildpack that either downloads all the dependencies and runs through the same build process that brightbox uses, or use something like…
Heroku apps at the very least sit behind the heroku router, which I would assume is in the same datacenter. If the information in this quora answer http://www.quora.com/Scalability/How-does-Heroku-work is still valid,…
Unfortunately, Ruby 1.9.x is not copy-on-write friendly, mainly due to the garbage collection strategy. I would venture to guess that most Rails apps these days are running on some version of Ruby in the 1.9 series. So…
This bit of ruby should take care of it HashMap = HashTable = Map = Table = Dictionary = Hash And if you're feeling adventurous, Object.send :remove_const, :Hash
Literally reinventing the wheel
fwiw, I find the syntax definition in the ruby_parser gem at https://github.com/seattlerb/ruby_parser/blob/master/lib/rub... to be much easier reading, as it's written for racc (the ruby equivalent of yacc), although as…
Why has arithmetic become the universal example of currying and partial function application? Examples: "Currying", Section 9.3 of Programming in Scala (addition); Ruby 1.9.3 documentation for Proc#curry…
well, I hate to beat a dead horse, but here's a one-liner (ruby): (map1.keys | map2.keys).map(&:to_s).sort.join(", ").instance_eval { empty? ? "<none>" : self }
so this is horribly non-idiomatic ruby, but it was fun p ->(*_) { _.reduce({}, :merge).tap { |_| return "<none>" if _.empty? }.keys.uniq.map(&:to_s).sort.join(", ") }.({c:3,d:4,b:2}, {f:5,e:4,a:1}) p…
