What Hacker News says?
A while ago Google Docs even switched to using Etherpad-style operational transformation instead of diff-match-patch. Some pretty mind-bending technology here: http://www.codecommit.com/blog/java/understanding-and-applyi...

HN discussionA number of years back, I wrote an OT implementation in Clojure/ClojureScript as a hobby project [1] and learned a lot along the way. I even extracting out the core client/server implementations to their own package [2]. It's an incredibly fun topic, and one that's also really challenging. It also gave me first-hand experience with fuzz-testing where I could simulate all kinds of concurrent-edit conflicts and ensure…

HN discussionwell the top-level git data structure is pretty close to eg, Scala's Vector, which is an immutable container implemented as a tree with a high branching factor of 32. Modification to such a vector, rebound to a new variable, relies on structural sharing of the original ( http://www.codecommit.com/blog/scala/implementing-persistent... )

HN discussionI've seen most the points discussed several times already on python-ideas, python-dev lists -- that is at the very least some of the points have merit and if the author has anything new to add then these lists might be also the place to do it. > Even weirder, str and list both have find, but list does not have index (a related method). It is in reverse: both str and list has index() methods. str has find(). To find…

HN discussionBecause they're not new. Check this XML DSL for Ruby, March 2008 http://www.codecommit.com/blog/ruby/xmlbuilder-a-ruby-dsl-ca... What's happened here is that it's being done in a statically typed language which is harder than in a dynamically typed on. So, good job done.

HN discussionWell, Antlr ( http://www.antlr.org/ ) has replaced yacc for most of the practical work already. Daniel Spiewak also mentions parser combinators and how GLL parsers can be much easier to use and yet fast enough most of the time ( http://www.codecommit.com/blog/scala/unveiling-the-mysteries... ). He mentions parser combinators as domain specif languages for creating parsers ( http://www.codecommit.com/blog/scala/the-m…

HN discussionReminds me of the operational transformation used in Wave. http://www.codecommit.com/blog/java/understanding-and-applyi... I see they mention it in the paper, saying the difference is that Wave requires a central server to impose a total ordering of operations.

HN discussionI love Heroku's little "language and community" section of these articles when they add a new supported platform. For example, the link to the explanation of Scala's Hindley-Milner type inference method ( http://www.codecommit.com/blog/scala/what-is-hindley-milner-... ) definitely taught me something new about the internals of Scala, and in general a new topic in Computer Science. Congrats on shipping yet another su…

HN discussionYour concerns seem ill-founded given that these are solved problems. There are working implementations of low-barrier cross-language compatibility, today, for both the JVM and the CLR. Here's one example; Rhino provides pretty seamless bridging from JavaScript to Java: https://developer.mozilla.org/en/Scripting_Java I've used it to run user-supplied JS inside the JVM. PHP is pretty easy too: http://quercus.caucho.co…
