[Linux] Inkscape vector drawing program

I recently found this vector drawing program for Linux as a lightweight and libre alternative to Illustrator: http://www.inkscape.org

It looks very promising and it renders graphics and fonts very well with very nice effects (if properly installed). It can even render Latex math formulas using Effects->Render->Latex formula. And the nice thing is -- it converts the formulas to vectors, so no bitmaps are used, giving an amazing quality improvement to text in the drawings.

I am using Gentoo and I had to enable the plotutils use flag and re-emerge pstoedit in order for Latex rendering to work in Inkscape. The next thing I'd like to get working would be to have some easy way of specifying a Latex preamble so I could use my macros and commands when typing the formulas. A larger space for typing the formulas would also be part of my wish list.

Before Inkscape, I have been using OpenOffice.org draw, which is quite decent and has a good EPS export, although its rendering capabilities are far from Inkscape's, and it doesn't support reading SVG as of this time. OpenOffice.org can render Latex formulas if you use OOoLatex http://ooolatex.sourceforge.net - and it even supports a user-defined preamble. However, the formulas are in bitmap format only.

The main reason for my attempt to switch to Inkscape is that the effects (such as many options for stylized strokes) and rendering are way better than Open office draw. However, OOoLatex still is superior in certain features, for instance you can edit the formula and correct mistakes, something impossible with inkscape 0.45.1

Angela's website

This is my girlfriend's website
www.guzdesign.com

Her name is Angela Guzman and she is a Graphic designer and Industrial designer. She crafted that
website Guz Design a long time ago but still looks cool. She will supposedly
update it soon with lots of interesting stuff she's been doing at her
master's program at Rhode Island School of Design. Angela loves making patterns, playing with typography, and combining 3D and 2D approaches to design.

photos!

I have been posting more photos at my album:

http://cortex.lems.brown.edu/~rfabbri/gallery

I will leave them public for a while, but after that you'll have to
ask me for password.
You also need a password in order to access my complete photo collection which includes a lot of older stuff.

Key Lime Pie

This is a nice & simple dessert from the Florida Keys.

6 egg yolks 1 can of condensed milk. (No evaporated milk!) 4oz of Key lime juice (maybe lemon or lime juice will work too)

Blend eggs and condensed milk, pour juice slowly while blending, then beat like a cake. The longer you beat, the puffier it gets.

Oven temperature at 325F, 15min. Let it cool, then freeze.

vxl vgui compilation workaround (and others)

In this post and the comments section below are various issues encountered while compiling VXL under Linux, and how I solved them.

To solve the following errors, put a blank "opengl_xmesa_include" in cmake. I have NVIDIA drivers and everything works fine after this.

make[1]: *** [core/vgui/tests/CMakeFiles/vgui_test_events.dir/all] Error 2 Linking CXX executable vgui_test_front_back /home/rfabbri/cprg/vxlprg/vxl-bin/lib/libvgui.a(vgui_accelerate_x11.o): In function `vgui_accelerate_x11::vgui_copy_back_to_aux()': /home/rfabbri/cprg/vxlprg/vxl/core/vgui/internals/vgui_accelerate_x11.cxx:426: undefined reference to `XMesaGetCurrentBuffer' /home/rfabbri/cprg/vxlprg/vxl/core/vgui/internals/vgui_accelerate_x11.cxx:435: undefined reference to `XMesaGetBackBuffer' /home/rfabbri/cprg/vxlprg/vxl-bin/lib/libvgui.a(vgui_accelerate_x11.o): In function `vgui_accelerate_x11::vgui_copy_aux_to_back()': /home/rfabbri/cprg/vxlprg/vxl/core/vgui/internals/vgui_accelerate_x11.cxx:458: undefined reference to `XMesaGetCurrentBuffer' /home/rfabbri/cprg/vxlprg/vxl/core/vgui/internals/vgui_accelerate_x11.cxx:467: undefined reference to `XMesaGetBackBuffer'

[Linux] Some NFS issues

I wanted to share partitions via NFS. I followed: http://gentoo-wiki.com/HOWTO_Share_Directories_via_NFS At first I got the errors:

* Error starting NFS daemon

and

clientmachinename:/directory/to/export: Function not implemented

The mistake was to skip the kernel compilation step. Simply build modules for NFS server and call modprobe nfsd. You don't even have to restart your machine.

Valgrind for profiling

Valgrind is amazing. Not only it does memcheck, it also does code profiling without need to recompile everything. Use it with kcachegrind, and you can see a very nice visualization of the profiling data.

suddenly no sound in linux

Card: Intel ICH5 Chip: Analog Devices AD1981B

Today I tried to play a CD rom and I suddenly got no sound in linux; very weird. After some fooling around, the solution was to turn off "Headphone Jack Sense" in alsamixer. Allright, hope someone can benefit from this.
