I’ve been a rather happy lua user for a few years. In particular, the luajit implementation. But as part of an ongoing overhaul of this and that, I decided to rewrite all my lua code in go. Or wait, let me rephrase that.

I wanted to make an interactive terminal interface for something. Usually I just bang out some vt100 escapes to move the cursor around, color this, erase that. It’s crude but effective as long as the number of screen elements is kept to a minimum. This time, though, I decided on a slightly more disciplined approach, and so I was looking for a library that might assist in drawing views of various sizes, and input fields, and buttons. The works. In go.

I mostly like go, but after working with it a bit more I realize there are a few jibs of which the cut I do not like.

I had some go code I wanted to quickly iterate on. Go compiles pretty quickly, but not instantly. Like 2 seconds. In some places, I can use gopher-lua, which gets me pretty close to 0 second iteration delay, but there’s a big up front development cost. It’s useful for scripting an existing program and adding custom behavior, but less useful for experimenting to see what happens when I do X. What I need is an actual interpreter for go, not an interpreter in go.

I have some go code that I’d like to be a little more flexible at runtime. Like a config file, but maybe with some conditional logic based on string matching. If this sounds like a proxy deciding which filtering functions to apply based on URL, that’s a good guess.

Imagine, if you can, a smaller version of the web. A web without dickbars, or scroll jacking, or chum boxes, or popup video, but still a web filled with informative articles about the 27 blockchains you need to be using right now. The good news is this web exists, but unfortunately your browser doesn’t connect to it by default. For that, you need the miniwebproxy.

Another little adventure in web page rewriting. I wanted to use a few more go features, and make something that would work on at least a few different sites via the Host header.

Is it crazy that a Medium post about javascript bloat would have itself have megabytes of javascript and stylesheets? I wouldn’t know, since I didn’t see it. I have a little proxy like service running that rewrites its HTML. This particular service was an experiment to replace some python code with go, to evaluate suitability for future hacks.

Depending on language, compiler, and runtime, sometimes the garbage collector needs a few hints from the programmer. You know you’re done with an object, but to the GC, if a variable appears live, it can’t be collected. Sometimes the problem really is programmer error, as objects continue to collect in a container that’s never inspected. Other times the variable will be overwritten soon enough, but does it help to overwrite it sooner?

At the g2k14 hackathon in July, I thought about a new interface for SSL connections. One of the most frequent complaints from OpenSSL users was that it was too much work to do anything, and one of the most frequent complaints from advanced users was that it was too much work to do anything correctly. Notably, failure to check the hostname in the cert against the hostname of the network connection is an unfortunately common mistake. And so was born the ressl (reimagined SSL) interface. Joel Sing (jsing) ended up implementing it first, putting the libressl in LibreSSL.
