Hmmmmm
Από cosmo.gr:
"Εντυπωσίασε η Madonna στην πρεμιέρα της περιοδείας της [...] Καθισμένη σε ένα διαμαντένιο θρόνο που είχε έμβλημα το «M» [...] έκανε την εμφάνισή της η Madonna στη σκηνή του Millenium Stadium του Κάρντιφ
[...]
Για μια ακόμα φορά, χρησιμοποιεί τη σκηνή για να περάσει πολιτικά μηνύματα, καθώς προβάλλονταν βίντεο με τις μορφές ανθρώπων που εργάζονται για παγκόσμιους σκοπούς όπως ο Bono και ο Al Gore να εναλλάσσονται με εικόνες από χώρες που σπαράσσονται από πόλεμο και πείνα."
Hm.

νυχτοπάππαρος, e-nictopaparus (ego)
"Στην Κύπρο απαντώνται 16 είδη νυχτερίδων από τα οποία τα 15 ανήκουν στα μικροχειρόπτερα και είναι εντομοφάγα. Μόνο ο νυχτοπάππαρος ή νυκτοκόρακος (Rousettus aegyptiacus) ανήκει στα μεγαχειρόπτερα και είναι φρουτοφάγο"

Humor in Operating Systems Books
In "Operating System Concepts", (Avi Silberschatz, Peter Baer Galvin, Greg Gagne) while explaining the notion of multiprogramming:
- "This idea is common in other life situations. A lawyer does not work for only one client at time. While one case is waiting to go to trial or have papers typed, the lawyer can work on another case. If she has enough clients, the lawyer will never be idle for lack of work. (Idle lawyers tend to become politicians, so there is a certain social value in keeping lawyers busy.)"
- "None of it is even remotely practical in real systems.
Its main function seems to be keeping otherwise
unemployed graph theorists off the streets."

κι αυτόν τον καραγκιόζη τον Αλ Γκορ
"Αυτό που με κάνει σκανταλιάρη, πάντως, είναι το politically correct. Τη σάχλα αυτή τη σιχαίνομαι - τη μοντέρνα οικολογία, τους οικολόγερους και τις οικολόγριες κι αυτόν τον καραγκιόζη τον Αλ Γκορ. Παίζει και στην παράσταση! Είδα το ντοκιμαντέρ «Μια ενοχλητική αλήθεια». Αυτός υπέγραψε για βομβαρδισμούς στο Ιράκ και τη Γιουγκοσλαβία και σου λέει μετά ότι δεν φταίνε τα πλουτώνια, πρέπει ν' αλλάξεις τη λάμπα και να κλείσεις την τοστιέρα..."

The Kerkis Font Family (Latex pack good, TTF bad)
The kerkis font family
http://iris.math.aegean.gr/kerkis/
produces some great results, especially on latex documents and especially in greek. So you just include the kerkis package in your latex document (\usepackage{kerkis}) and you get something as pretty as this:

But beware: This font, when installed as a TTF in windows (that is, pasted in the windows/fonts directory) can cause the gdi plus windows xp library to crash! After installing the fonts yesterday, applications such as YzDock, objectDock and similar ones kept crashing on start-up. Then I noticed ms office 2008 word crashing, and finally photoshop CS2. These apps all crashed on gdiplus.dll, except word which crashed on some other dll. After a few system restore attempts, msconfig configurations, I thankfully ended up in this thread, of a forum. Yes, I had installed a third-party font. So, after a good laugh, I thought that I should warn people getting similar errors...
I want to make clear that this is about the truetype fonts installed in the windows/fonts directory and has nothing to do with the latex package which works great. If you want to install the true type fonts then do so, they can be easily removed if similar problems occcur ( go to windows/fonts directory and delete them )

Crooked Tree

My kids are starting to notice I'm a little different from the other dads. "Why don't you have a straight job like everyone else?" they asked me the other day. I told them this story:
In the forest, there was a crooked tree and a straight tree. Every day, the straight tree would say to the crooked tree, "Look at me; I'm tall and I'm straight and I'm handsome. Look at you; you're all crooked and bend over. No one wants to look at you." And they grew up in that forest together.
And then one day the loggers came, and they saw the crooked tree and the straight tree, and they said, "Just cut the straight trees and leave the rest." So the loggers turned all the straight trees into lumber and toothpicks and paper.
And the crooked tree is still there, growing stronger and stranger every day.

Mr. 1 thought that "Gandhi-ism and all it stands for will, sooner or later, have to be grappled with and finally crushed". Also, that "It is alarming and also nauseating to see Mr Gandhi, a seditious Middle-Temple lawyer, now posing as a fakir of a type well-known in the East, striding half-naked up the steps of the Vice-regal palace...to parley on equal terms with the representative of the King-Emperor". And: the apartheid state.
No need to talk about Mr. 2, I think. Quoting his democratical and peace-loving words "I don't see why we need to stand by and watch a country go communist due to the irresponsibility of its people. The issues are much too important for the Chilean voters to be left to decide for themselves", "Power is the ultimate aphrodisiac" etc.
Mr. 3 let us all know about the threat of the ManBearPig . Also he wants us to know that we will save the world if we unplug the TV while we sleep [but travelling with his private jet(s) is ok].
To Mr. 4 we should bow.
Mr. 1 was voted greatest Briton. Mr 2 and 3 got a nobel peace price. Mr 4 didn`t.

OpenGL, Glut and Intel 945GM
Running an OpenGL app on a laptop with an Intel 945GM (128 shared) graphics card, I got a little disappointed by a couple of things such as the low fps. But the major problem was quite strange: artifacts, dissapearing polygons. Anyway turns out that the default value for the depth buffer in the OpenGl settings for the graphics card was 16 bits. So what you should do if you are having problems with OpenGL apps (mine was build with glut) on this kind of graphics cards is:
- right click, graphics properties (or the long way: right click, properties, settings, advanced, select the Intel Graphics Media Accelerator Driver and then click on Graphics Properties)
- From the menu, click the '3d Settings' button
- Finally, change the Depth Buffer Bit Depth from whatever it is to 24 Bit Depth Buffer.
