From WordPress to ePublishing (1)

Posted on by

Perhaps, the tips and tricks I did receive to turn a selection of wordpress-posts into a proper ePub-file may be of use to others, so I will describe the procedure here in some detail. It makes a difference whether or not some of the posts contain TeX. This time, I’ll sketch the process for non-LaTeX… Read more »

What’s Pippa got to do with the Bourbaki wedding?

Posted on by

Last time we’ve seen that on June 3rd 1939, the very day of the Bourbaki wedding, Malraux’ movie ‘L’espoir’ had its first (private) viewing, and we mused whether Weil’s wedding card was a coded invitation to that event. But, there’s another plausible explanation why the Bourbaki wedding might have been scheduled for June 3rd :… Read more »

NeB : 7 years and now an iPad App

Posted on by

Exactly 7 years ago I wrote my first post. This blog wasn’t called NeB yet and it used pMachine, a then free blogging tool (later transformed into expression engine), rather than WordPress. Over the years NeB survived three hardware-upgrades of ‘the Matrix’ (the webserver hosting it), more themes than I care to remember, and a… Read more »

Seating the first few billion Knights

Posted on by

The odd Knight of the round table problem asks for a consistent placement of the n-th Knight in the row at an odd root of unity, compatible with the two different realizations of the algebraic closure of the field with two elements. The first identifies the multiplicative group of its non-zero elements with the group… Read more »

So, who did discover the Leech lattice?

Posted on by

For the better part of the 30ties, Ernst Witt (1) did hang out with the rest of the ‘Noetherknaben’, the group of young mathematicians around Emmy Noether (3) in Gottingen. In 1934 Witt became Helmut Hasse‘s assistent in Gottingen, where he qualified as a university lecturer in 1936. By 1938 he has made enough of… Read more »

To most mathematicians, a good LaTeX-frontend (such as TeXShop for Mac-users) is the crucial tool to get the work done. We use it to draft ideas, write papers and courses, or even to take notes during lectures. However, after six years of blogging, my own LaTeX-routine became rusty. I rarely open a new tex-document, and… Read more »

Seriously now, where was the Bourbaki wedding?

Posted on by

A few days before Halloween, Norbert Dufourcq (who died december 17th 1990…), sent me a comment, containing lots of useful information, hinting I did get it wrong about the church of the Bourbali wedding in the previous post. Norbert Dufourcq, an organist and student of Andre Machall, the organist-in-charge at the Saint-Germain-des-Prés church in 1939,… Read more »

Snow leopard + wordpress + latex problem

Posted on by

Ever since I’ve upgraded to Snow Leopard I’ve been having problems with the webserver. At first there were the ‘obvious’ problems : mysql-connection lost and php-error message. These were swiftly dealt with using the excellent Snow Leopard, Apache, PHP, MySQL and WordPress! advice from ‘tady’. Right now, access to this blog is extremely slow (and… Read more »

Last time I promised to come back explaining how to set-up LaTeX-support, figuring I had to tell you about a few modifications I had to make in order to get Latexrender run on my mac… A few google searches made it plain how out of touch I am on these matters (details below). But first,… Read more »

the King’s problem on MUBs

Posted on by

MUBs (for Mutually Unbiased Bases) are quite popular at the moment. Kea is running a mini-series Mutual Unbias as is Carl Brannen. Further, the Perimeter Institute has a good website for its seminars where they offer streaming video (I like their MacromediaFlash format giving video and slides/blackboard shots simultaneously, in distinct windows) including a talk… Read more »

iTouch as network sniffer

Posted on by

In the iTouch warwalking post I was considering trying to gain access to closed networks for innocent purposes such as checking mail, rather than stealing secret passwords from people allowing you free access to their wireless network, but still, I should have thought of the following possibility Here’s a walk-through : type the following command… Read more »

Archimedes’ stomachion

Posted on by

The Archimedes codex is a good read, especially when you are (like me) a failed archeologist. The palimpsest (Greek for ‘scraped again’) is the worlds first Kyoto-approved ‘sustainable writing’. Isn’t it great to realize that one of the few surviving texts by Archimedes only made it because some monks recycled an old medieval parchment by… Read more »

Vacation is always a good time to catch up on some reading. Besides, there’s very little else you can do at night in a ski-resort… This year, I’ve taken along The Archimedes Codex: Revealing The Secrets Of The World’s Greatest Palimpsest by Reviel Netz and William Noel telling the story of the Archimedes Palimpsest.

When more than 200.000 websites are using google analytics, a one-man action proposed last time to de-activate GA on neverendingbooks is pretty useless. Perhaps a better alternative is : When you use google analytics on your site, announce this and add a link to CustomizeGoogle BLOCK GOOGLE ANALYTICS COOKIES. Your visitors can then decide whether… Read more »

MacBookAir? Is this really the best Apple could come up with? A laptop you can slide under the door or put in an envelop? Yeez… Probably the hot-air-book is about as thick as an iTouch. The first thing I did was to buy a leather case to protect the vulnerable thing, making it as thick… Read more »

Wiki on iTouch

I’ve reduced the springboard of my jailbroken iTouch to a minimalistic Dock consisting only of the iPhone Mail.app to read and write mails properly (as opposed to having to use webmail on an unbroken iTouch), an RSS-reader to watch other math-blogs and the arXiv (via Install.app under Productivity/MobileRSS), the Safari webbrowser and a Finder (via… Read more »
