Hmph! Not sure which one is "correct" there... hmm... If you use kCGImageAlphaPremultipliedFirst for the CGBitmapContext rather than kCGImageAlphaNoneFirst, then it looks closer to the original, maybe. ? Also other caveat: NSBitmapImageRep can't seem to deal with the ARGB format either, so if you use that you need to…
I’m not sure why I decided to create an Erlang backend for the PureScript compiler.The platform is somewhat interesting, but I didn’t know it, and I don’t ha...
On the relationship between mixed-radix bases and array indexing
This Daily Mail piece by David Derbyshire is so profound it has been cited over and over: How Children Lost the Right to Roam in Four Generations: an interview with four generations of the same family about how far they were allowed to wander as kids. It comes from Britain but will sound familiar to
Mostly my opposition to Clojure is the JVM. That sh*t is heavy. This came up in the ZA Tech Slack team several weeks ago. While watching some Clojure talks...
If you've ever used an arithmetic mean, a Pearson correlation or a standard deviation to describe a dataset, I'm writing this for you. Better numbers exist to summarize location, association and spread: numbers that are easier to interpret and that don't act up with wonky data and outliers.
