kruhft writes: Virtual memory is useful for a number of things, but can takes up a large amount of die space and development time during the development of a CPU to be both efficient and correct. With the advent of 64+ bit architectures and cheap memory available today, an extended address space and paging aren't specifically needed for many tasks. Memory safe, high level languages need less 'isolation' and 'protection' from a VM subsystem than traditional languages like C and C++. Page tables help the OS organize non-contiguous physical memory for applications, but is that as much an issue today, especially for symbolic and object based languages?
If one was to design a new 'high level' language CPU today, would it be seen as advantageous to include a traditional multi-level page table based virtual memory system, or could the resources be put to better use in other areas of the chip design?
 The primary benefits of virtual memory include freeing applications from having to manage a shared memory space, increased security due to memory isolation, and being able to conceptually use more memory than might be physically available, using the technique of paging.
kruhft writes: sxc is an S-Expression based language transpiler that has the feel of C wrapped in parenthesized expressions that compiles to standard C code. This structure allows for the creation of code generation macros using the full power of the host Common Lisp environment, a language designed for operating on S-Expressions, also known as Lists. It is unknown exactly what power might come about from this combination of low level processing with high level code generation. Can you think of any possible uses?
kruhft writes: An Emacs Lisp JIT compiler has been released showing a 25% speedup improvement with the benchmarked raytracer. Using libjit, it 'compiles down the spine' of the bytecode vectors, moving the overhead of the interpreter loop into the hardware execution unit. Work in progress, but a good start on speeding up emacs overall. Thoughts?

Image, audio and video file preview is supported by the client.
Most file sharing sites store your data on their servers for a period of time before they distribute your files; with Drop, Click, Paste! simply keep the tab open to continue sharing and seeding your files. Built using Web Torrents so no central server storage is required, maintaining your data privacy and the file distribution network load is shared across all users. The future of file sharing is here and it's dead simple to use. Give it a try today!

Can anyone on Slashdot provide some insight into whether this proof is correct? And if so, why have we not heard of this sooner?"

Traditionally, high frequency traders seeking the fastest connections between markets have looked to fiber-optic networks. It's been a largely successful endeavour. Latency between the markets of Chicago and New York has been cut as low as 13.3 milliseconds.
But experience tells us that this is an industry that never sits still. In pursuit of the even faster times that can make all the difference in high frequency trading, some firms are looking to wireless solutions to give them the edge."

This past Sunday, the 1334 votes from a Turing test held at the Techniche festival in Guwahati, India were released. They revealed that Cleverbot was voted to be human 59.3% of the time. Real humans did only slightly better and were assumed to be humans 63.3% of the time. That being the case, Cleverbot's success in conning people into thinking it was human is greater than chance, and therefore, one could argue that it has technically passed the Turning test."
kruhft writes: "I was recently doing some research into Genetic Programming and found through a blog post that looks to be useful. After looking over the code and license, I found that this was the first piece of code I had seen that was protected by a patent, issued on June 19, 1990. I read that patents last for 20 years, meaning that the patent that this code refers to is expired. Is there any way for me to be sure that using this code is safe from any patent troll attacks if I choose to use it? Would rewriting the code keep me from violating any other patents that the author might have regarding the use of such an algorithm? Does the code pass into the public domain after the patent expires?"
