Re: [gentoo-user] Question of quantum computer
I forgot again . As far as i know , there isnt any Quantum os out there . Just qcpus performing a very simple algorythm. Because the particles still cant hold their state for long enough.
Re: [gentoo-user] Question of quantum computer
Btw . If the universe where that easy yo destroy ,it would already be destroyed. Is just an estadistic question . Is just very improbable that we are the most advanced lifeform in it .

Ii think it is about Quantum bonds . In wich 2 particles share the same State at any distance .

You could do make allmodconfig . Have you try localmodconfig or localyesconfig ? El 02/10/2014 05:16, "Harry Putnam" escribió: > I want to install gentoo as guest with VirtualBox.

Re: [gentoo-user] duplicate HD drives
You are only cloning the first 512 bytes , remove the count parameter . It is usefull if you need to copy/restore the mbr .

Re: [gentoo-user] Re: Is LLVM bytecode the future ?
But what i mean is native code . Anyway , what about compile to binary lenguages like java (it won't run as native one , but you will remove a lot of overhead from the java vm ) , Or simply , a thing like .NET/Mono but at low level . And , of course , thanks for the answer , and your project is very interesting , i'll take a look . 2014-08-25 20:00 GMT+00:00 James : > Ivan Viso Altamirano gmail.com> writes: > > > > > This has little to do with Gentoo , but still it is a interesting debate > . > > You can compile a great sort of programing lenguages to llvm bytecode : > > C(++) , java , Objetive C(++) , C# , Haskell , Rust ...

[gentoo-user] Re: Is LLVM bytecode the future ?
Sorry , i accidentally send it . What i wanted to say is that , Theoretically , you can : 1) Native compile statically typed non-native lenguages 2) Recompile binaries for another architecture and even plataforms . 3) Achive a .NET like CLI , but even better . And , notice , that the LLVM garbage collector is a little precary . 2014-08-25 19:45 GMT+00:00 Ivan Viso Altamirano : > This has little to do with Gentoo , but still it is a interesting debate . > > You can compile a great sort of programing lenguages to llvm bytecode : > C(++) , java , Objetive C(++) , C# , Haskell , Rust ...

[gentoo-user] Is LLVM bytecode the future ?
This has little to do with Gentoo , but still it is a interesting debate . You can compile a great sort of programing lenguages to llvm bytecode : C(++) , java , Objetive C(++) , C# , Haskell , Rust ... And a lot more . On the other side , you CAN'T compile , lenguages like python or perl . The interesting part is that a feature under developement : It can decompile C(++) code to LLVM bytecode , (only if it not use plataform specific libraries or assembly code ) So , you can easily port your favourite X86 privative application to ARM or PPC , Just wonderfull .
