It appears that +SourceForge took over the control of the 'GIMP for Windows' account and is now distributing an ads-enabled installer of GIMP. They also locked out original owner of the account, Jernej Simončič, who has been building the Windows versions of GIMP for our project for years.

So far they haven't replied to provide explanations. Therefore, we remind you again that GIMP only provides builds for WIndows via its official Downloads page.
Source for version 2.8 (Stable). GIMP releases available from gimp.org and its mirrors contain the source code and have to be compiled in order to be installed on your system. For instructions, how to build GIMP from source code, please see this page.

Konrad Kyeser, 1366 in Eichstätt geboren, war der erste namhafte Autor nördlich der Alpen, der die überlieferte technische Tradition vor allem militärischer Nutzanwendungen zusammenfasste und möglicherweise auch um eigene Erfindungen und utopische Vorschläge bereicherte.
Die hervorragend erhaltene Handschrift enthält 173 meist ganzseitige kolorierte Federzeichnungen, die mit lateinischen Texten erläutert werden.

Hey, people of the web! Come join with me #TeamMolly and donate a bit. It's about helping this great woman: http://en.wikipedia.org/wiki/Molly_Holzschlag
 
Since #TeamMolly   twitter and FB members do not seem to have representation on Google+, I'm going to have to do the job. Here's the deal - I'm in bad, bad shape - and the description on this page is filled with inaccuracies that I will deal with at another time but in the meantime, please, consider passing this around, and even joining #TeamMolly  

I have no expectations and am filled with shame to even ask - despite the fact that the crowdfunding model is reasonable in a meritocracy where I never, ever placed material gain over the importance of the work. If I ever meant anything to you, please help me. I don't want to die. And if I do die, I want to go out with some kind of dignity in the home I worked for, and the solitude I believe I've earned after years of sharing so freely.

If I am being selfish, I'm so sorry. I wanted to be better than this, but I failed. I wanted to never have to ask another person for anything, but now I have learned humility. I have always been independent, and now I am angry because I have become dependent.

My heart is well and truly broken, but I believe in time that I can repair given the time, dignity and solitude to do so. Thank you and I love you always, and I'm sorry for the maddening lengths I appear to have gone in order to protect myself. It's quite simply been brutal.

Zeit über einen eBook-Reader nachzudenken. Oder?

Wir haben haben je ein Print-Abo von SPIEGEL, HH Abendblatt und c't und auf der Ablage Küche stapelt sich ein Haufen Altpapier. Der muss weg.

Also mal mit der simplen Frage "welchen eBook-Reader empfehlen Sie mir für Ihr Digital-Abo?" die Hotlines anrufen.

SPIEGEL: Ein Tolino wird als Prämie zum Print-Abo beigelegt, also ist es nur konsequent, dass es gar kein Digital-Abo für den Tolino, sondern nur für den Kindle gibt. Aber: Der digitale SPIEGEL für den Kindle hat keine Bilder, sondern besteht aus der lynx-Ansicht des Fließtexts. Im Jahre 2014.

Abendblatt: Es ist 2014 und die Abo-Hotline vom Hamburger Abendblatt kann mir nach 2x Weitervermitteln nicht sagen, wie teuer ein Digital-Abo für einen Kindle oder Tolino ist. Online finde ich dann heraus, dass das Kindle-Abendblatt weniger Artikel enthält als die jeweilige Print-Ausgabe.

Aber die c't, die müsste doch ganz vorne dabei sein, oder? Es ist 2014 und das digitale Abo der c't kostet genau so viel wie die Print-Ausgaben. Und es ist nicht an den Kindle oder Tolino angepasst.

Es ist 2014 und alle drei erwarten, dass man ihre Digital-Abos statt auf einem eink-Reader auf einem Tablet mir ihrer proprietären App liest oder man sich mit einer PDF-Kopie der Print-Ausgabe zufrieden gibt.

Und keiner bietet einen Familientarif an, bei dem meine Frau und ich beide auf je einem Reader den SPIEGEL lesen können.

Liebe Verlage, ich weiß auch nicht, warum Euch die Kundschaft überaltert und wegstirbt, während die Abo-Zahlen fallen. Wirklich nicht.

Es gibt nur eine mir bekannte Zeitung, die das mit dem Digitalabo richtig begriffen hat. Die Zeit. ePub, mobi, PDF, eigene App und Podcast für nicht halb so viel Geld im Monat wie die Printausgabe kostet. Auf Wunsch wird die Digitalausgabe per e-mail an den reader geschickt. Bei Fragen und Problemen wird schnell und kompetent geholfen. Der krasse Gegensatz dazu bei den Nürnberger Nachrichten treibt mir die Tränen in die Augen.

A detailed summary will follow as soon as possible, but this for a start: Despite comparatively few attendees, border:none 2014 was so great! We got a lot of new input and had big fun throughout the two days. Thanks to all the attendees, our crew and especially our great scene-setters +Aaron Parecki, Curtis Wallen, Jan-Christoph Borchardt, +Laura Kalbag, +Jeremy Keith, +Adam Ierymenko and Mario Heiderich — you made it what it was: a blast! <3

Massive Hangovers and the Harmonic Series

This picture shows a stable deck of 52 cards in which the top card overhangs the bottom card by about 1.5 card widths. In theory, it is possible to do even better so that the overhang is almost 2.26 card widths. The reason for this has to do with centres of mass and the harmonic series.

In order to understand where the number 2.26 comes from, it is helpful to keep track of the horizontal displacement of each card. We will measure horizontal distances from an origin at the rightmost edge of the top card, in such a way that each card is 2 units wide. The centre of mass of the top card is then 1 unit to the left of the origin. 

The overhang of a stack of cards is the horizontal distance between the rightmost edge of the top card and the rightmost edge of the bottom card. In a stack of two cards, the way to create the largest overhang is to put the centre of mass of the top card above the rightmost edge of the lower card. The combined centre of mass of these two cards will then be half way between their individual centres of mass; in other words, 1.5 units to the left of the origin.

Now consider creating an overhanging stack with n+1 cards by placing an overhanging stack with n cards on top of a single card. (This is probably not a good way to create a stack in practice, but it is mathematically helpful.) In order to maximize the overhang, the cards should be positioned so that the centre of mass of the top n cards is directly above the rightmost edge of the bottom card. If we define C(n) to be the horizontal distance between the centre of mass of the n-card stack and the origin, this shows that the size of the overhang for n+1 cards is equal to C(n).

The centre of the bottom card of the new n+1 card stack is at a distance of C(n)+1 from the origin. The centre of mass of the new n+1 card stack is thus given by the weighted formula
C(n+1) = (nC(n) + C(n)+1)/n+1,
which simplifies to C(n+1) = C(n) + 1/(n+1). 

Since C(1) = 1, we can solve this to show that C(n) is given by the sum of the first n terms of the harmonic series, H(n) = 1 + 1/2 + 1/3 + ... + 1/n. A famous property of this series is that it diverges to infinity. For example, if you were prepared to make n large enough, you could add up enough terms to make H(n) larger than 1000, or any other large number you care to specify. However, the divergence is very slow, and adding up the first million terms of the series only gives a total sum of about 14.39.

Going back to the skewed stack of 52 playing cards, we now know that the size of the overhang for 52 cards is equal to H(51), which works out at around 4.5188. However, the width of a card is two units, so in terms of card widths, the maximum overhang is about 2.2594, which is where the figure of 2.26 comes from. 

Since the series H(n) diverges to infinity, it is possible in theory to stack objects in this way so that the overhang is arbitrarily large. However, the thicker and heavier the objects become, the harder it is to achieve large overhangs.

This post is based on a post in the blog ThatsMaths by Peter Lynch, who is a Professor of Meteorology at University College Dublin. The blog post also shows a photograph of a stack of ten biscuits (cookies) and a stack of ten volumes of the Encyclopædia Britannica
