Awesome :) Great work on the blog by the way, it's going into my morning reading list.

I'm working on join algorithms at the moment, so I spent the last few months getting up to speed on the latest research. The rest is just from general interest. I spend around ten hours a week reading papers or textbooks. Whenever I fi

@ibdknox ported Light Table from node-webkit to atom-shell a few weeks ago ( https://github.com/LightTable/LightTable/tree/atom-shell ). I haven't looked at it myself, but I heard some noises from him abou

Typed Objects are a huge step forwards but they still have some limitations. I frequently use things like: solverStates = { numVars: uint32 numConstraints: uint32 numStates: uint32 solverStates: solverState[num

LLJS is listed here but the last commit is over a year ago. Having spent the last month hand-coding arrays of structs in js, I'm really feeling the need for better low-level constructs. Looks like I'm stuck waiting for rust + emsc

This is wonderful work. I wonder how long it will take for software archeology to become a real field? So much is forgotten already.

The ocaml runtime is wonderfully simple ( http://rwmj.wordpress.com/2009/08/04/ocaml-internals/ ) and the compiler focuses mostly on good codegen rather than advanced optimisations. In practice, it's

That's a reasonable question, I don't see why it was downvoted. We don't plan to make money from Light Table. We will continue to maintain it but our main focus now is Eve ( http://www.chris-granger.com/2014&#x

That's for building from source, which is only necessary if you want to back on Light Table itself or write a plugin.

The video on the front page of http://lighttable.com was made in April. Most of the changes since then have just been bug fixes so its pretty representative of the current state. Now that we've removed the bottlenecks on o

The decisions were largely separate. The goal of having a CA was to leave us the option of selling commercial plugins in the future. We no longer plan to do that so we got rid of it. Separately, we kept hearing that the GPL is a hurdle to a

Firstly, dual-licensing requires that all contributors sign a CA, which is enough of a annoyance that many minor fixes just don't get contributed at all. Secondly, Mike Innes ( http://junolab.org/ ) is one of the big con

I just ran flow on our js constraint solver and it caught a bug. The dirty checker used && instead of & to check the dirty variables bitflag against the interested propagators bitflag so it was silently doing more work than it h

Datalog is relational. Both of those papers show datalog compilers in datalog.

I saw a related issue on emscripten-fastcomp saying they are based off the pnacl fork of llvm, which is why they are lagging behind. I'm hoping we can use rust eventually but it doesnt look like the kind of problem we can just throw mo

Unfortunately most (all?) of them have performance costs and we are already eyeing up asm.js for better performance.

I really wish I could use rust for my current work, but it has to be runnable in the browser and it looks like it would take a lot of work to get emscripten on to the same version of llvm as rust. I just spent two hours debugging what turne
