Tweaking Ubuntu for the Lenovo Flexpad

I don’t like to get new equipment if I have old equipment that still works fine. My Asus A2500S laptop is now more than 10 years old, and although it has received a few small repairs and a memory upgrade over the years, it still works fine. Its Pentium ...

Batch search & replace in PDF files

The other day I found out I had misspelled a word in a whole batch of automatically generated PDF files. Regenerating all of them would be a lot of work, as the PDF files were plots created using perl/PDL, gnuplot and epstopdf (available in texlive-extra-utils), and the input data ...
