161. Re: Lua/LuaJIT2 performance on Android (score: 16)

I really like your "marketing" :) Can't wait for for it... I have one (maybe dumb) question - usually, when floating point performance of a CPU is bad, you can make use of fixed point arithmetics usi

For one thing, tables are often not very useful as table keys. Do you want to use bit arrays as table keys? This fails even if an __eq metamethod is defined: t[{true,false}] = true; assert(t[{true,fa

Of course, another approach is to use virtual file systems (such as FUSE or Windows 7 VHD). The "EXE" would actually be a VFS with code to mount it and then start a secondary EXE within the VFS. The

I wonder if there's some reason no other language (that I know of anyway) allows more than one return value for a function. Maybe because it's not such a great idea to have a non-deterministic number

I think you have to be very careful about making this case. How tolerant of backwards-incompatibility do you thing the Lua user base would be if the Lua authors modernized the language to support ze

LOL! I have a feeling you are trying too hard: you're trying to calculate when to do what and by how much.. It's impossible and unnecessary -- you should be much lazier. I'm very serious about this,

Just for a reference, this is how LuaX allows static/dynamic linkage of a module: - No changed necessary in module source code (this is important!) - By default, modules are compiled dynamically, 'Gl

Thank you Luiz Henrique for sending 4.1-work4. I suspect that my original http transfer got cut short. I was praising Lua yesterday to an ex-student of mine who is about to take up a job with a Dutch

So you mean, this would work already for current Lua 5.4? Without change of Lua source code? Sorry for too many questions... I do not really understand how you would use "fixed userdata" to instruct

Hi, bel TLSF is a good choice. What do you think about it? Or any other available choice? And I agree that the allocator function is the key factor. But as you said that the "special" purpose real-ti

Counting the number of bits can be improved a lot instead of using successive shifts by 1 bit, you can at least compute the number of bits set in a 32 bit integer in a very few operations, without an

Ok, good argument for this being a change request and not a bug report. Agreed. I did. It took about 6 hours for a prototype implementation. Someone who knows lua internals better than I do should b
