Yes, code is data, but that's not what makes Lisp cool
There has been some debate on Hacker News lately about what makes Lisp cool , in particular about whether the secret sauce is homo-iconici...

Learning to program is getting harder
I have written several books that use Python to explain topics like Bayesian Statistics and Digital Signal Processing. Along with the books...

A look at the J language: the fine line between genius and insanity (2012)
I’ve been looking for a decent TSDB for years now. Took a shot at writing one in Lush using HDF5 (as others have done), but the experiments I did raised more questions than I got answers. I&#…

Just what does “code as data” mean anyway? (2014)
Recently, I’ve seen popular articles on macros and metaprogramming in Nimrod and Elixir . Both of these are wonderful metaprogramming systems, to be sure, but I couldn’t help but imagine some in the audience smirking inwardly – and occasionally less inwardly. What odd syntax! How out-of-place they are! If only there…

The Benjamin Franklin method for learning more from programming books
The Benjamin Franklin method for programming books: read a code sample, close the book, and rewrite it from memory to truly learn it.

Sum Types Are Coming (2015)
Just as all mainstream languages now have lambda functions, I predict sum types are the next construct to spread outward from the typed functional programming community to the mainstream. Sum types are very useful, and after living with them in Haskell for a while, I miss them deeply when using languages without them…

Picking Apart the Crashing iOS String
So there’s yet another iOS text crash, where just looking at a particular string crashes iOS. Basically, if you put this string in any system text …

Shipping a Neural Network on iOS with CoreML, PyTorch, and React Native
This is the story of how I trained a simple neural network to solve a well-defined yet novel challenge in a real iOS app. The problem is unique, but most of what I cover should apply to any task in any iOS app. That’s the beauty of neural networks.

Advantages of monolithic version control
Someone : Did you hear that Facebook/Google uses a giant monorepo? WTF! Me : Yeah! It's really convenient, don't you think? Someone : That's THE MOST RIDICULOUS THING I've ever heard. Don't FB and Google know what a terrible idea it is to put all your code in a single repo? Me : I think engineers at FB and Google are…

Speeding Up Ruby with Shared Strings
It’s not often I am able to write a patch that not only reduces memory usage, but increases speed as well. Usually I find myself trading memory for speed, so it’s a real treat when I can improve both in one patch. Today I want to talk about the patch I submitted to Ruby in this ticket. It decreases “after boot” memory…

Zombie Processes Are Eating Your Memory
Zombies probably won’t consume 32 GB of your memory like they did to me, but zombie processes do exist, and I can help you find them and make sure that developers fix them. Tool source link is at t…

An opinionated guide to Haskell
For me, this month marks the end of an era in my life: as of February 2018, I am no longer employed writing Haskell. It’s been a fascinating two years, and while I am excitedly looking forward to what I’ll be doing next, it’s likely I will continue to write Haskell in my spare time. I’ll probably even write it again…

The insane amount of backward compatibility in Google Maps
I still keep a couple of my favorite old smartphones. Sometimes I use one of them as my primary device for fun. Phones are among the fastest evolving markets, even a year makes a whole lot of differences. One of the biggest challenges with using old phones is the software: they don't run modern software. And old…

Interactive GPU Programming, Part 2: Hello OpenCL
This is really the same article as Part 1 - Hello CUDA, but with the focus on OpenCL, so I'll skip most of the narration and just show you the code.
