Have you ever wanted to design your own programming language? It seems like such fun, but if you’ve ever tried you probably got stuck right around the time you read “LLR Decent Parsers and Abstract Syntax Trees.” Traditionally designing your own language was hard because it requires a very specialized...

This blog is based on my talk from NodePDX 2016. You can watch the full video of my session, or read my other writings on my personal blog. Today I’m going to build a casual Massively Multiplayer Online game. Something that can have 50 or more people playing at the same time. And I’m going to do...

Household appliances are not the kind of thing consumers really get excited about; they’re no iPhone. But thanks to the Internet of Things (IoT), that seems to be changing. It is now easy, inexpensive, and a lot more fun to create connected devices in every area of life, from cars and homes to...

In the three previous posts in this series, we learned how to use Ohm to parse numbers, build an expression tree, and process blocks of code with conditionals. In this final post on the Ohm series, we will finish up our complete programming language, Meow, with looping and real function calls. Thanks...

Welcome back! In our first Ohm post, we introduced Ohm and built our very own parser to handle numbers in various formats. In our second post, we turned our parser into a real arithmetic language with binary operations and symbols. Today we will give our language code blocks and conditionals.  ...

Middleware Functions, a new feature of the PubNub Data Stream Network that lets you move computation into the network itself, allowing your apps to go completely serverless. Check how Functions work. How does it secure potentially un-trusted code? How does it keep one app separate from another? How does...

We’re excited to announce Functions, a better way to do serverless computing at scale with real-time data. Now you can program the data network itself to do your bidding, compute real-time data, combine multiple webservices into a single workflow, and conjure a gelatinous cube with only spoony bard....

Last time I introduced Ohm, an open source meta language parser with an easy to use syntax, we built a parser for different number formats. Basically, I showed you how to easily build your own programming language with just a few lines of code. This week we will extend the parser to calculate arithmetic...

Voting online and seeing the results instantly on the web is a very convenient way to conduct quick surveys or pop polls. But you already know that because of the primary season. This real-time voting tutorial was made for the first technical workshop I led as an evangelist intern this summer, a at YouTube’s...
