I'm very surprised to hear this: I've submitted several artefacts; co-run an AEC for a (small-medium) conference; and spoken to a lot of people about it. I've heard virtually nothing negative until your post. Indeed, the arte

The Rules of the Game is a fascinating book because it starts with the lead-up Jutland, goes back in time to explain how the culture and personalities of the Royal Navy came to be, before going back to Jutland. It made my head hurt the firs

My gut feeling is that one can minimally maintain systems in "forgotten" languages indefinitely if they're basically stable and feature complete. But it seems that people come unstuck for systems that still need to evolve --

Sulong is a really good idea -- I wish I'd thought of it first! We've had a student do a small project looking at something equivalent for RPython. There are, as expected, no show-stoppers yet, but I have no idea how far we'l

Why Python and PHP? There are several reasons, but the major ones were: we had to start somewhere ; we had an excellent Python interpreter available to us, as well as a fairly decent PHP interpreter; and PHP and Python turn out to be rathe

Both V8 and LuaJIT are extremely impressive but I'm not sure either dominates the other, at least when I last benchmarked things < http://tratt.net/laurie/research/pubs/files/metatracing_vms/.

I'm not aware of a direct comparison of Perl and PyPy. However, for a paper I co-authored, we put together an experiment with various languages and VMs, using the language shootout plus a few other benchmarks: http://tratt.net/laurie/re

I know myself that I had a high regard for LuaJIT before benchmarking, and an even higher regard for it afterwards. Richards is an oldish benchmark, and none of the subsequent versions (Lua, Python, Converge) is exactly "native", so I'm not

Yes, on synthetic benchmarks for LuaJIT-2.0.0-beta10 and PyPy 1.9. Those numbers need updating for the latest versions, but the basics are as follows. LuaJIT is incredibly fast to warm-up. On short benchmarks (around a second or less), it i

If you have a static type system and it's sound, it'll reject some programs that would execute without type errors, whereas a dynamically typed language will allow such programs to execute: it's what I called "dynamic expressivity". That's

I agree fully with the author - exceptions are a problem for software that wants to avoid unexpected behaviour. I noted something similar in http://tratt.net/laurie/tech_articles/articles/a_proposal_fo... and sketched a possible compromis
