Totem python console

Today I learned that you can script Totem Movie Player 2.28.2 with the python language. There is even a python console included as a plugin to Totem.

On the screenshot you can see a few commands in the console to play, pause and seek on a video or a sound file.

Linking to places in Excel

Much like you can link from a table of content in word to the corresponding title in the document, I wanted to link an Excel cell to another cell inside the document (for example to the cell A5). The problem is that if a new cell is inserted above the destination cell (changing it from A5 to A6 for example), the original link doesn't change the destination cell's number (it stays to A5).

So I decided to use the "name range" possibility. But as explained here, "If the cell or range already has a name you may type a new name in the name box and it will be accepted as a name for that cell or range as long as it is not a name that is currently used elsewhere. However, the first name given will still exist and will still be the one shown in the name box when you select the cell or range. In formulas etc. You will still be able to use both the new name and the old name. "
Here (in 2004) they proposed to use a VBA function, but that is actually not nessecary.

The solution is to use the "Name Manager" dialog box. From Excel help: "Use the Name Manager dialog box to work with all of the defined names and table names in the workbook. For example, you may want to find names with errors, confirm the value and reference of a name, view or edit descriptive comments, or determine the scope. You can also sort and filter the list of names, and easily add, change, or delete names from one location.

To open the Name Manager dialog box, on the Formula tab, in the Defined Names group, click Name Manager."

And the way I solved my problem was by using the "create from selection" dialog in the "defined names" area of the formula tab.

Setup of programs I use daily

Research Software

• LyX to write articles and structured documents including citations, Check my blog post on LyX
• JabRef to manage a bibliography
• LaTeX to typeset publications, exported in PDF format
• R statistical software and the R-Studio application
• Several packages: plyr, ggplot2, FAOSTAT, testthat
• Knitr and R Markdown to produce work reports in html. Knitr and LaTeX to produce more elaborate reports in PDF
• xlsx to write data frames to Excel

OS

• Debian GNU-Linux at work
• Ubuntu and Lubuntu at home
• Until 2014 windows XP and windows 7 at work 

Office Software

• I use Firefox (renamed iceweasel on Debian) for web browsing, with the following extensions:
• Adblock to block annoying ads
• Delicious bookmarks to have mobile bookmarks across many browsers
• Mindthetime to keep track of time usage. This extension is not working any more.
• For simple image editing I use Irfanview. I crop scanned pictures or screenshots and I redimension them for web use or use in documents. Very occasionally, I use the "sharpen" function or the brightness, contrast, gamma corrections. 
• I use Microsoft word and Excel at work. I use Google documents when writing something at home.
• To work collaboratively I use media wiki with the extension Semantic Mediawiki
• Based in this review, I installed spacesniffer it helps analyse disk space usage on windows. Like Disk space analyser on GNU-Linux systems. You can use filters such as this one: "*.jpg;>100kb;>2weeks" to filter only certain type of files, sizes and dates.

Command line tools on GNU-Linux

• du to analyse disk usage. I created an alias duh for du -h.
• grep to search inside text files
• pdfgrep to search inside pdf documents
• git see programming below

Thesis writting

• Writing documents in Lyx
• Keeping track of versions with git
• Managing a bibliography with Jabref.

 Programming software

• Scite to edit code
• Git to track versions of code. See also git commands and posts tagged with git.

I want to test

• hubic remote for git annex
• Etherpad (within a company) 
• Kaban (within a company)
• Sage mathematics software 
• Panda data analysis because it brings data frame structures to python
• Montage Video sur ubuntu and Ubuntu video tools

 I stopped using

• QuickWiki Quick search of definitions
• Zotero to share search results with colleagues
• Mendeley to insert citations in Microsoft Word and to manage a bibliography (can import bibtex files form Jabref) 

Links

• On this blog, linux users describe their setup
• usethis.com another site where users such as Yihui Xie describe their setup.

Singularity - the opinion of Peter Norving

Interview of Peter Norving: "Do you agree with Kurzweil's forecast regarding the singularity?"

"So Ray is great and I appreciate all that he's done, I appreciate all the advances in AI that he has done in reading, in music and so on, so he's a great technologist. I think in terms of these predictions, euh, I think he's doing the best he can by saying, I wanna nail down this prediction, I'm gonna look at the data that we have, I'm gonna extrapolate from that data and come up with an answer, euh, I think the only problem is that the data is not conclusive, right. So you look at, Moore's law, yes, you can say computers are going at this particular rate, but I don't think you can necessarily say that when we pass a certain number of transistors, that corresponds to a certain number of neurons and therefore the 2 are equivalent, I think that's where the analogy breaks down."

What are your thoughts on molecular manufacturing and Bio-Engineering?

"So it's fascinating to me, euh, I'm trying to learn something about it. I'm educating myself, I gotta long way to go. I think it does tie-in because it is a mix between the physical world and the world of information. Euh, I think it is likely that in the coming century a large part of manufacturing will be done with cells or with atoms. I kind of think it'll be more done with cells than with atoms just because they're bigger, they're easy to manipulate, they've already got this 3 Giga bite computer on board, we just gotta figure out how to program it."

Peter Norving is director of research at google.

Home server

This company is selling a home server. For what it's worth! ;-)
They are based in Anger, how bizarre! And their website is in French and German.

Python, Delphi and oracle

"In Greek mythology Python, serpent, was the earth-dragon of Delphi, always represented in Greek sculpture and vase-paintings as a serpent. She^[1] presided at the Delphic oracle, which existed in the cult center for her mother, Gaia, Earth, Pytho being the place name that was substituted for the earlier Krisa.^[2] Hellenes considered the site to be the center of the earth, represented by a stone, the omphalos or navel, which Python guarded."

From the wikipedia article Python (pythology) (nice typo! :).

In computer fields
python is a programmin language and Delphi too. Oracle is a software company and you wonder where their inspiration came from.
