Finally, I am trying to reorganize this website, add a portfolio and other kind of stuff that will help me remember the ton of stuff I wrote but never talked about. I'll document in this article the different kind of things I tried. I am especially excited by the portfolio aspect (of which most will be private though).

A circular slide-ruler
We had this conference in Chicago in 2016. As I was playing with the laser-cutter and making planetary motion devices see Here, I also was playing with the idea of circular slide rulers. As the calculation of elution volumes and retention in CCC and CPC are using multiplications and divisions it is possible to do these on a circular slide ruler (or a normal one) by using logarithmic scales (because additions in that space correspond to multiplications in linear scale).

Someone toying with a laser-cut award
We had [this conference](https://gfp.people.uic.edu/ccc2016/) in Chicago in 2016. As I was playing with the laser-cutter and making planetary motion devices, Guido asked if it wouldn't be possible to make two awards for the conference. I also made a [Slide ruler](/article/20170530_cccslider) for that conference. A bit of design, metallic-gold acrylic, flexible metallic with black background acrylic for the tag, and a piece of wood made by a colleague (Jim).

A cat that has been transformed
This article is in english, but the original one is in french. Just because many english-speaking people asked me about these transforms. (Cet article est en anglais, même si l'original est en français. C'est juste parceque on m'a plus souvent demandé en anglais qu'en français plus d'informations sur ce sujet. Mais ça devrait être plutôt clair pour les francophones.) Through my migration to o-blog v2.5 I found some old experiments I did with FFT related to this Rapport d'écoute - Sur les épaules de Darwin (France Inter) - La forme des mots

I use Notmuch to manage my emails (and that's just wonderfully fast) and use the Emacs frontend for it. But when I wanted to save attachements, it was not that easy to create folders. I had to exit the save, open a terminal, a dired or whatever create the folder… I use Helm for managing completion in emacs (and that's a nice piece of software too).

To avoid that and with the help of Sacha Chua, I managed to add a shortcut in helm read file:

A cat that has been transformed

Suite à l'émission de France Inter « Sur les épaules de Darwin, La forme des mots », j'ai décidé d'expérimenter un peu avec la conversion d'images en sons par transformée inverse de fourier.

Pour cela, j'ai utilisé le logiciel ARSS, un peu vieillot, mais qui fait ce qu'il a à faire.

Commençons par un petit exemple, transformons l'image de la formule de cette fameuse transformée en son avec la commande :
