Garbage collection is a particularly cross-cutting implementation issue, and tends to interfere with all kinds of abstraction. You're essentially making a system that knows which specific ways abstraction can be broken safely, so that

Lua has access to the filesystem, but you probably want the luafilesystem module for general scripting, it provides more POSIX and Windows-specific functionality. As a general rule, the Lua standard library only includes what can be portabl

As Scott Locklin said in a parallel comment, J already comes with excellent documentation and tutorials. This would be a better starting place: http://www.jsoftware.com/jwiki/FrontPage As a language, J isn't ever

You'd be surprised. I'm more familiar with k (kona) than J, but many of those seemingly inscrutable blocks of punctuation become recognizable as a unit pretty quickly. You can, of course, break huge expressions like that apart and

I saw a patch he wrote for copying coroutines, for those who miss multi-shot continuations.

Lua has always supported integers, as a compile time setting. Instead of having a full numeric tower, it has a LUA_NUMBER type that can be changed (doubles, by default), and also makes adding new numeric types at runtime (such as libGMP big

Thanks. :) I'm still mostly using Lua 5.1.4 most of the time, and I forgot to include that.

I agree, they're tricky. I'm currently working on a blog post about them. :)

This is a good start, but there's also some deeper ideas in Lua. It has a good implementation of coroutines, for example; if you're familiar with continuations from Scheme, they fit most of the same uses. (They're like genera

Part 1 of the post ( http://spin.atomicobject.com/2013/05/02/chicken-scheme-part-... ) focused on CHICKEN, this one focuses on SPOCK, a Scheme that compiles to JavaScript.

I wrote a similar tool to this in C, ff ( https://github.com/silentbicycle/ff ). The main difference is that, where `ffind foo` appears to be comparable to find . -name "*foo*" , ff is closer to

I've had and enjoyed both. The latter has less about the fundamentals, but adds chapters on real-time GCs, concurrent GCs, and other advanced material. (Most of whose research probably came out after the first edition.) If you're interested

My focus on licenses so far only really concerns making it easier for vendors like the OEM to use my library. When I open-source hardware layouts, I now know I need to investigate license details for hardware-specific language. (I don't hav

If you have any other recommendations for making this process smoother, please let me know. I want people in your situation to be able to use my libraries without these irritations. (Author of the post.)

The MIT, ISC, and zlib do not seem to, and the OEM is happy with the ISC. I didn't check the GPL, because its overall design conflicts with my intent. Here's the ISC license, in its entirety: Permission to use, copy, modify, and/or di

I probably cannot discuss the specifics of the vendor, but I don't know if First Sale applies in their country. I'm not a lawyer, and their lawyers brought it up as a potential issue, so I'm inclined to take it at face value.

The "public domain" designation has its own problems, nicely summarized on Google Code ( https://code.google.com/p/support/wiki/FAQ#Can_I_host_code_t... ). In particular, Dr. Richard Hipp (SQLite's main author) has talked about problems tha

It was never my intention that people who use my open-source library complicate their supply chain by pushing additional work onto their customers. The paperwork wouldn't necessarily just mean slapping a post-it™ note on the product, it c

It is straightforward if you read the license closely with hardware in mind , but I've been releasing stuff under the BSD license for much longer than I've been doing embedded development. I thought I knew what the BSD license meant, but m

Author here. I don't think the BSD license is broken, just that the legal implications of that clause were surprising to me, and I thought I'd share what I learned. I'm still likely to use the BSD license in other contexts, but will probabl

A tenth of a second seems to be a common threshold for how long something can take before it becomes a noticeable delay. (I've seen 75 - 200 msec in UI literature.)

I use lua for that, and it seems to be a very good fit. There's awk influence in its history, so it's probably no accident.

I had to implement my own malloc/free/etc. on an embedded project recently, due to a lack of thread-safety in the vendor's C stdlib * . I wrote a blog post about it ( http://spin.atomicobject.com/2013/04/17/embedded-memory-unde... ), with a
