Business card can be handy in many cases, and it's not a big deal to create it at home. Let me show one of the methods.
We need to have:
matte presentation paper (weight 44 lb/165 g/m2 in my case);razor paper trimmer (I've used X-ACTO 12" Personal Paper Trimmer, but can't recommend it - it has a habit to stuck in the middle of the trimming process);printer (don't know about laser printers, but ink one works fine for me);LaTeX software.
The last point can be challenging, because LaTeX is not so smooth and user friendly as it can be. My basic recommendations:
install Perl (it's required by auto-pst-pdf package);update/install all the required LaTeX packages (e.g., some Linux distributions provide incredible old LaTeX packages);use "-shell-escape" command line option for pdflatex command;if nothing helps, don't use "auto-pst-pdf", but build DVI/PS file, and convert it to PDF. Single business card
The code (based on LaTeX QR Bas…
UPDATE (07/18/17): The original article was written in 2011 and pretty much outdated, I've updated the numbers and conclusions.
I've got a question about which programming language is preferable for the website development for embedded systems (with limited resources). Here is my small investigation in a table form. Please note that the question was about only these 3 programming languages - there are better candidates for the embedded systems now (for example, Rust).
The Memory and Performance overhead numbers are based on the n-body benchmark and calculated as relatives to "C gcc #4" measurements.
Memory consumption is slightly specific to my area of software development now, but I did some research recently and maybe these results can be useful for others. Of course, I know that precious comparison is very difficult to carry out, but actually I needed only overall picture. And let me admit that results are pretty interesting and even frustrated (at least for me).
As a basis I took so-starving project, and measured initial RSS (Resident Set Size) of the each process (local development webservers). Platform: x86_64 Linux (latest Ubuntu with all updates).
As a reference, here is the RSS of the interpreters in interactive console mode:

One more reference - the most simplest WSGI app (example in the Python documentation). It's RSS: 7336Kb, so I assume it's almost impossible to consume less memory without additional tweaks and optimizatio…
