23C3: Who can you trust?

It starts fairly early this year: even FeM is already preparing and planning for this years live streaming and recording. The public wiki of 23c3 is online and even the Call for Participation screams: visit me!

So, remember: beside the official wiki pages, you can always come and check here for information about FeM activities on 23c3…(streaming, recording,…)

spot the IIS…the space station not the web server…

“A number of amateur astronomers and Space Station enthusiasts regularly take photos as ISS rises above the horizon in westerly direction and sets towards the East. In response to a recent article on this website, you sent us some of your ISS images. A selection of your photos is presented below.”

Weizenbaum. Rebel at Work.

Peter Haas and Silvia Holzinger did a film called “Weizenbaum. Rebel at Work.” and I think you should hear about it:

“The film spans 8 decades of Joseph Weizenbaum’s life. It provides a stage for his humorous narrative depicting a World of Yesterday while reflecting on the dawn of the computer age. It follows 83-year-old Weizenbaum on some of his numerous public lessons, effortlessly entertaining overcrowded lecture halls.

The old man is an up-to-date chronicler, a chief witness against militarism and the myths of technological progress, but he remains a modest, funny and most reflective story teller.”

It’ll be available in german language in august and later this year in english.

How to make things smaller

No, you won’t need a hammer to do the things I write about in this article. You will need a camera and a special lens.

this actually IS the Roman Colosseum

“To create this effect, Barbieri uses a tilt-frame camera to shift the plane of focus so that it is out of alignment with the film. Normally, this allows wide-angle aerial views to be captured in proper perspective. But used incorrectly, an optical illusion occurs.”

Persistence of Vision is not only a raytracer…

Yesterday I wrote about the bike mounted POV display. And today? Well. It’s a real huge display:

“Spin uses Persistence of Vision to create the illusion of a cylindrical
digital display (computer screen), 12 feet tall and 12 feet in diameter. Vertical
columns of multi-color LED (light emitting diode) clusters spin around a vertical
axis at 90 revolutions per minute. At a radius of 6 feet, they move at 41 miles
per hour. 2880 LEDs are turned on and off by a computer in precise synchronization
with the rotation of the columns, creating the illusion of a cylindrical digital
display. Spin has a vertical resolution of 16 pixels (picture elements), each
of which can display one of 8 colors. As horizontal position is determined by
time in Spin, the horizontal resolution is theoretically infinite, but for the
sake of data manipulation efficiency it is be limited to 360 pixels all the
way around the cylinder.”

new holographic display technology…

Wow this looks awesome compared to any holographic display technology I could take a look on to this date. Now I do know what 50 Gbytes of storage space could be useful for…

“Invented by Tibor Balogh, these flat panel “holo TVs” are capable of displaying images in 3-D — or so it seems.”

quite a refreshing drink: Ipanema

The temperatures raise these days. And I have this great limes. So what else could I do than transforming limes+cane sugar+passion fruit juice+ginger ale+ice into this really refreshing drink called “Ipanema”. It’s just like a Caipirinha. But without the headache afterwards.

Rechnen an der Uni

In den heutigen, von Terrorgefahren verunsicherten Zeiten, passen sich die Menschen auch an ganz unerwarteten Stellen den Gegebenheiten an.

Aus dem aktuellen Statistik-I-Übungsskript, Aufgabe 20:

“Unter den 20 Passagieren eines Charterfluges befinden sich zwei Bewaffnete, die das Flugzeug entführen wollen. Zehn Passagiere werden zufällig ausgewählt und genau untersucht. Wie groß ist die Wahrscheinlichkeit dafür, dass die beiden Bewaffneten unentdeckt bleiben?”

Na dann, frohes Rechnen…

Masterchiefs’ Warthog is a Peugeot…

I have to admint that when I first drove the Warthog in HALO 1 my first thought was “It’s a french car! The steering is so indirect and tipsy like in every french car I drove to this point.”

And who would have thought that I was right? (well beside of moi) It’s a PEUGEOT! It’s a concept car and therefore it’s worth a lot of money…though it lacks the turret on the back…

Artefakte aus vergangenen Zeiten

Ab und an findet man Gegenstände, die irgendeinem Zweck dienen, früher einmal jedoch ganz andere Aufgaben erfüllten. So kamen bei einer Schrottentsorgung einige davon ans Tageslicht.

Was hier als Kinderboot umfunktioniert wurde, ist in Wahrheit ein Zusatztank für ein Messerschmitt-Jagdflugzeug.

In diesem Kasten wurden nicht immer Schrauben aufbewahrt, sondern auch einmal 7,92mm-Geschosse für Wehrmachts-MGs.

Noch ein ominöser Behälter – für ABC-Ausrüstung bei der Wehrmacht.

Manchmal sind solche Fundstücke sogar wertvoll.

the invisible bookshelf

I was in Bamberg the second half of last week to help my girlfriends mom moving into the new apartment. And since she has so many books it would be a great eye-catcher to just “stick” some of them on the wall. This invisible bookshelf is in stores for 18 euros. Which is… quite expensive for a bended piece of metal… but it looks so great.

Escher, Escher and even more Escher

“The work of M.C. Escher needs no introduction. We have all learned to appreciate the impossibilities that this master of illusion’s artwork presents to the layman’s eye. Nevertheless, it may come as a surprise for some, but many of the so-called ‘impossible’ drawings of M. C. Escher can be realized as actual physical objects. These objects will resemble the Escher’s drawing, of the same name, from a certain viewing direction. This work below presents some of these three-dimensional models that were designed and built using geometric modeling and computer graphics tools.”

the gumball 3000 ’06

Every year again the “race” begins. Well it’s not a race per se – but a rally. This year the gumballers will start at sunday morning in London and arrive 8 days later in LA.

The difference this year: All of them are guided by a Windows Mobile powered device with ALKs CoPilot software. (ALK is one of the sponsors)

Silver Bells and Golden Spurs

“Silver Bells and Golden Spurs is an exploration of the movie making capabilities of Second Life. It serves as a proof of concept for doing such, as well as the need for certain technical improvements.

With all the available Second Life tools, customized avatars and animations, and with the help of Bedazzle Studios, I knew we could create a high quality, compelling movie.

I first read the anonymous poem in a collection of cowboy poems I picked up several years ago, and immediately knew I had to make this story into a movie. I made notes in the margins of the book describing camera angles, dolly moves and crane shots. When I ran out of room, I decided to adapt the poem for the screen. In the screen play I could accurately describe the action in each scene, and use it as my guide through the production process (just like a real movie is made).

Pulling information from the script, I created lists for props and set pieces, avatar animations, audio, and costumes. These helped streamline the production and assured that no details were overlooked.

The set and all of the props were created on a single simulator, maximizing visual quality while minimizing overhead. I met regularly with the set modeler, character animator and costume designer to review and discuss the progress of their work. Although I had a very specific mental picture of what everything should look like, I needed to allow each of these artists the latitude to explore and use their creativity.”

Blick durch die Parteienlandschaft

Achtung – Satire!

Am 26. März sind wieder Wahlen – in Sachsen-Anhalt. Als vorbildlicher, nicht politikverdrossener Mensch habe ich mir natürlich rechtzeitig die Briefwahlunterlagen besorgt, da ich am Stichtag nicht zu Hause bin.

Abseits der großen Volksparteien tummeln sich wie immer hoffnungslos unsinnige Ansammlungen von Menschen, die wirklich glauben, sie werden von jemandem gewählt, obwohl ihr Progamm vielleicht den einen oder anderen anspricht:

AGFG – Außer Gerd fürn Gulli (einer der Bewerber heißt Gerhard Schröder, zumindest schon mal das cleverste Marketing)

BBW – Biete besseres WLAN (für die Geeks)

DVU – Durch Vernichtung unterwerfen (Tja, Demokratie…)

REP – Rammeln extrem pervers (Noch ein Punkt für die Demokratie)

FP Deutschlands – Fundamentale Pazifisten Deutschlands

MLDP – Mit List durch Polen

Pro DM – Durchsicht monatlich

DKP/KPD – Du (für) Kopftuch (und) Prophet / Kalaschnikow (und) Paradies (für) dich

STATT Partei – Suche tagsüber Aushilfsjob trotz Tarif

GUT – Gern unter Tempo

Wählen macht doch Spass…

Jens Heymann
