GPU's as CPU's

Would'nt it be great if we could throw our CPU processors out and use only our video card GPU's ...

I am proposing just that idea , but with a twist instead of just NVIDIA CUDA and other GPGPU interfaces , we could design a whole new OS with microkernel architecture and distributed processing in the desktop box itself.

This i beleive could get a more usage of the GPU hardware and make processing cheaper and efficient.

Building your Linux system from scratch : Missing Links

Monday, February 12th, 2007

By Deepak Barua

I just built my linux system from scratch with some difficulties and now i want to configure the X windows and other graphical eye candy but first i wanted to help other adventurers like myself on their journey.

Include details about what is LFS (a version of linux – I presume). URL for download etc. Any Wiki links. Supported by who etc. What is so enticing about LFS compared to RedHat, SuSe, Debian and other flavors ?

As this article appears to be additional instructions to building your own Linux, it might be good to verify this revised process by enlisting the help of someone over the net to follow your steps and see if they are successful.

Getting Started

I was following the LFS stable version 6.12 which is very good but certain things i needed help from uber-geeks ( few highly regarded friends of mine).

What specific items your contact suggested helped you complete the build. Are those steps already captured in this document?

Can these steps be scripted so that I can simply run the script and out comes a Linux CD – won’t that be cool.

So i started first by downloading all the packages and the required patches , mind you when making the first temporary system almost no patches are required.

Dynamic Linker

As you are following the instructions in LFS 6.12 you reach the part wherein the details about the dynamic linker are explained, please don't try to move or delete this file as it is critical to your host system functioning if it gets corrupted in some manner most programs in the system will stop working as they cannot find their shared libraries.


Also when building the glibc package make sure you untar the glibc-linuxthreads package in the glibc source directory.

This package can be obtained from http://ftp.gnu.org/gnu/glibc/

cd glibc-2.3.6

tar -xzf glibc-linuxthreads-2.3.6.tar.gz

This is one of the addons which need to be incorporated into the glibc package while compiling so make sure you specify to include addons when performing the configuration for glibc

../glibc-2.3.6/configure –prefix=<depends on temporary or final compilation>      --disable-profile --enable-add-ons      --enable-kernel=2.6.0

The above specified steps need to be executed during the temporary glibc compilation and also make sure they the directories are exist in the final glibc compilation and installation.

Glibc Manual Installation

Sometimes during the final installation of glibc by issuing a command “make install” you might get some errors related to the manual directory such as

make[2]: *** [libc.info] Error 2

To correct this we need to remove the make install rules in the makefile, this is not the best solution but then these manual files are not important to glibc and we want a working glibc compilation.

.PHONY: install subdir_install installdirs install-data

install-data subdir_install: install

ifneq ($(strip $(MAKEINFO)),:)

install: $(inst_infodir)/libc.info

@if $(SHELL) -c '$(INSTALL_INFO) --version' >/dev/null 2>&1; then

test -f $(inst_infodir)/dir || $(INSTALL_DATA) dir $(inst_infodir);

$(INSTALL_INFO) --info-dir=$(inst_infodir) $(inst_infodir)/libc.info;

else : ; fi


# Catchall implicit rule for other installation targets from the parent.

install-%: ;

$(inst_infodir)/libc.info: libc.info installdirs

for file in $<*; do

$(INSTALL_DATA) $$file $(@D)/$$file;



$(mkinstalldirs) $(inst_infodir)

These errors are due to sometimes incorrect versions of texinfo or other bugs in the documentation.

Flash Programmer for 89V51RX2

I finished my flash programmer for 89V51RX2 series of phillips 8051 processors in tcl /tk here is it on 8052.com



Robotics Project

My robotics project is going along fine just created a new mobile robotics platform and writing my own flash programmer in tcl to get control of the board.

I'll give you more news as it happens.

Controlling Abortions

Hi everybody,
This new proposal by the govt is quite shocking http://economictimes.indiatimes.com/Govt_to_monitor_pregnancies_abortions/articleshow/2201445.cms
might lead to a blackmarket in abortions just like in the US...
IMO govt controlling anything more important something personal is a bad idea.
