Yes, FFT is an algorithm, a computer-optimized implementation of the Fourier transform. Speaking of optics, the famous slit-experiment, where you can see the diffraction patterns of light passing through one or more slits, is the fraunhoffe

Yeah but kind of expensive... I believe the best combination would be a small telescope to learn the basics of the sky and then if you want to go deep, rent the iTelescope service.

You know when toddlers try to put a round peg in a square hole? that's how it feels using functional programming in a turing-machine-like CPU. It just don't fit.

Yes I do enjoy movies but I'm not constantly looking at movies. Also, easy and useful is the best kind of useful. Easy and useless is well, useless.

Chill dude, call yourself a hacker if you wish, has no strict definition anyway. I believe "fun" and "easy" projects have no merits, them being hardware/software/whatever (unless you are in high-school) It&#x2

Creating useful things is also very fun. And takes about the same time/energy. Anyway, doing stuff with a raspberry pi has no hacker merits IMHO. Anybody can connect stuff to a portable supercomputer and make it do things.

Raspberry Pi is great and easy to work with. I got it, I don't need 5 inane projects per day to remind me about it. I particularly like this one, but for me life is too short to waste time in useless projects.

I agree, it's like a microkernel, you only have to add a microkernel.

by aortega 13y ago
It depends. Being downvoted by people that believes a memcpy() is a kernel, is victory.

I'm not talking about privsep, just different modules. I gonna answer you with another question: Did MS-DOS had a kernel?
344.
by aortega 13y ago
They are called libraries.

by aortega 13y ago
Kernel means "core". Kernel-mode-only kernel is a contradiction. If you don't have separate parts, you can't have a core.

by aortega 13y ago
Great! except that to be called a kernel it's missing just a process manager, memory manager, filesystem, process separation and hardware abstraction. Yeah I'm that guy, down vote me as you wish, the article is still wrong. It&#

This article assumes -e working in netcat, that is not the case since many years ago. For -e to work, you have to compile netcat.c defining GAPING_SECURITY_HOLE, one of the best self-documenting options there are. Needless to say, most dist

Most BSDs kernels have an emulator mode when they accept int 0x80 syscalls. Some parameters are different than Linux though.

The bitstream format, at least for Xilinx, is not that obscure. Actually was documented in an old application note.

Indeed, I always wonder why such a (relatively) exotic and low-volume technology is also very low-cost. 3 minutes is very fast...one of my projects takes about 30 minutes for ~30K Luts on a modern Core I7, I used too many registers. Develop

I believe the problem here are the Xilinx tools. They basically suck. Latest Quartus from Altera can build a decent sized (about 10000 LUTs) design in about 10 minutes in my I5 M2520 notebook. I'm currently synthesizing a 45nm ARM cort

I wonder why Xilinx choose to use the j32 CPU in this example when they have better designs like the MicroBlaze, with about same size but faster and able to boot Linux. EDIT: Oh I see. Microblaze is propietary and didn't exist back the

Very few common user tasks can be solved more efficiently with an FPGA than with a CPU or GPU. CPU gives you speed in computation. Except for a custom ASIC, nothing can match a modern CPU in single thread speed. GPUs gives you parallelism.

Yeah, maybe I should have said 50 instead of 30. I forget we are in 2014, my mind still is in the 90's. Miscalculation.
