I created a table from /dev/random, /dev/urandom and a time trend. The time trend was to confirm that random behavior of /dev/urandom and /dev/random were indeed random by picking a random number and then incrementing it to create an upward trend.

Arabic numbers.

I have to say that I thought this concept was terrible funny. Enough so that I hazarded a go at art.

I love arabic numbers.

TeX capacity exceeded, sorry [main memory size=5000000]

LaTeX is a weird bird. I ran out of memory. The solution: add the line "main_memory = 8000000" to the file /usr/local/texlive/2015/texmf.cnf

$ sudo fmtutil-sys --all

It's worth noting that 8000000 seems to be the maximum value.

\strip@pt undefined in LaTeX, and the fix.

I could not get the statement \strip@pt in LaTeX to parse. It would always just give an undefined value. The solution is to change context, which is such as hack, but that's how you do it.

\documentclass[journal,letterpaper]{IEEEtran}
\usepackage{fp}     

\begin{document}
\newcommand\bitfieldwidth{32}  
\newcommand\bitfielddivision{8}
\makeatletter
\FPeval{\bitcolumnwidth}{(\strip@pt\textwidth) / \bitfieldwidth}
\makeatother

\begin{tabular}{|c|c|}
\hline
variable & value \\

On the temperature dependence of subthreshold currents in MOS electron inversion layers, revisited

I presented a paper, on a paper: On the temperature dependence of subthreshold currents in MOS electron inversion layers. Yannis Tsividis even came to my talk at ISCAS 2016 and he told me that he took the data that Ulmer and Card used!

CMOS processes have become much better, and self-aligned CMOS have really helped MOSFET behavior become amazingly well behaved. The MATLAB that was used to extract and analyze the data is available here: http://www.nectix.com/research/subvt-temperature.html

Reverse engineering a RFID tag

I've been designing a RFID tag from scratch. It's mainly because what I want cannot be purchased. My tutorial from IEEE RFID 2016 is now on my georgia tech research page research page. Next year I think that I'll split it into a very technical talk, and a more touchy-feely demonstration and introduction talk.

I like art, I'm just bad at it.

I love the arts because I am not good at them. Semiconductors is a better core competency for me than music ever could be. I saw that Ken Barnes was trying to raise money for a movie that is a mixture of Vertigo and Body Heat.

The Origami Man seems like it would be really cool if he can get it off the ground.
