Anders Hejlsberg talking on the new C# and VB features for the version to follow C# 4.0 (timecode 48:10): [Async methods] allow you to compose asynchronous stuff using normal flow of control and using all of the statements that you know already. Pretty sweet. The first (longer) portion of the presentation is on the new […]
Eric Lippert of Fabulous Adventures In Coding has posted a series on CPS tranformation and different control flow abstractions. Good stuff — recommended reading for translating the crazy stuff I talk about into ‘normal’ code. Continuation Passing Style Revisited, Part One. Continuation Passing Style Revisited Part Two: Handwaving about control flow. Continuation Passing Style Revisited […]
Oracle sues Google over Android and Java | CNET News. Wow. Sun may have open-sourced Java in the past, but at this moment, the JVM seems like a more hostile platform than .Net.
The Island and Lake Combination. For those who are curious which is the largest (island in a lake on an)^2 on an island. Because recursion isn’t just for programmers and computers.
Came across a slide deck via Reddit with an excellent point, cutting across the various functional programming diciplines: Central to the thesis of FP is the notion of referential transparency. Referential transparency leads to program compositionality. // #1 X x = function(); R r1 = arbitrary(x); R r2 = arbitrary(x); // #2 R r1 = arbitrary(function()); R […]
From “The Discovery of Continuations” The talk actually had one direct and important consequence for computing. Under the inspiration of the notion of the unnecessity of goto’s, Dijkstra spent that evening constructing realistic examples of programs without goto’s, … So while van Wijngaarden said that goto’s were unnecessary … , Dijkstra stretched the point to […]
Subtyping, Subclassing, and Trouble with OOP. Excerpt: What makes this problem more unsettling is that both you and I tried to do everything by the book. We wrote a safe, typechecked code. We eschewed casts. g++ (2.95.2) compiler with flags -W and -Wall issued not a single warning. […] And yet, despite all my efforts […]
