CHDK – the alternative firmware for many Canon Digital Cameras

“CHDK is a firmware enhancement that operates on a number of Canon Cameras. CHDK gets loaded into your camera’s memory upon bootup (either manually or automatically). It provides additional functionality beyond that currently provided by the native camera firmware.

CHDK is not a permanent firmware upgrade: you decide how it is loaded (manually or automatically) and you can always easily remove it.”

chdk

Main features:

  • Save images in RAW format
  • Ability to run “Scripts” to automate the camera
  • Live histogram (RGB, blended, luminance and for each RGB channel)
  • Zebra mode (blinking highlights and shadows to show over/under exposed areas)
  • An “always on” full range Battery indicator
  • Ability to turn off automatic dark-frame subtraction
  • a higher compression movie mode, and double the maximum video file size
  • exposure times as long as 65 seconds
  • exposure times as little as 1/10,000 of a second
  • ability to use the USB port for a remote trigger input

Additional features:

  • a depth-of-field (DOF)-calculator
  • File browser
  • Text reader
  • Calendar
  • Some fun tools and games

SPAM-Bots can decrypt Captchas… ups…

If you thought that those fancy Captchas would serve their purpose of SPAM prevention forever you might want to think again.

From Wikipedia:

“A CAPTCHA (IPA: /ˈkæptʃə/) is a type of challenge-response test used in computing to determine that the user is not run by a computer. The process involves one computer (a server) asking a user to complete a simple test which the computer is able to generate and grade. Because other computers are unable to solve the CAPTCHA, any user entering a correct solution is presumed to be human. A common type of CAPTCHA requires that the user type the letters of a distorted image, sometimes with the addition of an obscured sequence of letters or digits that appears on the screen.”

It usually looks something like that:

Captcha

Now the news:

“Websense Security Labs ThreatSeeker™ technology has discovered that spammers in their recent tactics have drawn their attention towards traditional and infamous Hotmail, aka Live Hotmail services after the streamlined Live Mail Anti-CAPTCHA operations. Spammers have managed to create automated bots that are capable of not only signing up and creating random Hotmail accounts, but also use these accounts for spamming purposes from a proper Live Hotmail service.”

when you think you’re invulnerable by using Amazon services

Oh last year I worked with many different companies that thought that the best thing they could do to increase their availability is to outsource their complete webserver and storage infrastructure to Amazon.

Now last week there was this 2 hour black out of parts of the Amazon S3 infrastructure which should have this “wake up call” effect for most of those hype-believers.

S3 is great for all sorts of applications but you – like in everything IT – really shouldn’t depend on just one service provider.

encrypting your world

One of the great good news in the last few days was the release of the brand new TrueCrypt 5 crypto-software.

I am using TrueCrypt for years now getting little and not so little container files mounted as drives and having the data warm and cosy encrypted on disk.

The long awaited features that were added in the brand new version are complete system – pre-boot authentification – drive encryption and OS X support.

Especially the system drive encryption is of particular interest for me. It’s a straight forward and completely painless solution to encrypt your complete machine and use it as if nothing was done at all.

The workflow is like this:

  1. Install TrueCrypt 5
  2. Fire up the TrueCrypt Volume Creation Wizard
  3. Select “Encrypt system drive” option
  4. It will do a test-run to make sure your machine can boot with the TrueCrypt Pre-Boot Authentification
  5. if everything worked out, TrueCrypt starts to encrypt your drive…
    truecrypt_drive

After that you’re set. On my brand-new machine the speed does not decrease noticeable – Even on my 4 year old machine I wouldn’t say that there is a slow-down at all.

You did notice that Xbox Media Center has a new homepage?

If you are – just like me – still using the very good and always updated Xbox Media Center for your slightly hacked XBOX 1 console you should take a look at the new XBMC.org website:

xbmcorg

Not only that these guys a making a great job creating the best Media Center that I’ve ever was allowed to use, they are even porting it to different platforms:

“It’s currently being ported to both Linux (x86 Ubuntu 32bit) and Mac OS X. Team XBMC is looking for talented developers to help with this effort.

Official XBMC software application names:

  • XBMC for Mac OS X
  • XBMC for Linux
  • XBMC for Xbox “

That means: If you have a OS X or Linux box, you should visit the site too and take a look at the (early) snapshots of XBMC for your platform.

Schrankmonster intern – USA

Von Zeit zu Zeit ist es von Interesse, zu erfahren, wie es um die eigene Webseite im Internet steht. Für einfache Statistiken gibt es entsprechende Log-Tools, die die Anzahl der Zugriffe über einen bestimmten Zeitraum messen, den verwendeten Browser und die Seite, von der der Zugriff erfolgte, anzeigen usw.

Mittlerweile gibt es aber auch Dienstleistungen, die sich auf qualitative Analysen spezialisieren, zumeist auf die Frage: Wer ist der Nutzer und wie kann man ihn möglichst interessengenau mit Werbung zupflastern? Etwas, was im Bereich des Online-Marketings sehr wichtig ist und natürlich Geld kostet (aber nicht muss).

Ein kostenloser Anbieter ist die Webseite www.quantcast.com. Eine Überprüfung für Schrankmonster.de ergab folgende Analyse über den typischen US-Nutzer:

Er ist

– männlich,

– weiß,

– zwischen 35 und 44 Jahre alt,

– verdient zwischen 30.000$ und 60.000$ im Jahr,

– hat zumindest einen College-Abschluss

– und keine Kinder zwischen 6 und 17 zu versorgen.

Darüber hinaus noch einige weitere Angaben:

– die Seite erreicht durchschnittlich 6.583 Nutzer im Monat,

– überdurchschnittlich viele Geringverdiener

– überdurchschnittlich viele Menschen, die weder weiß, schwarz, asiatisch noch Latinos sind (Wer bleibt da eigentlich übrig?)

– überdurchschnittlich viele ältere Menschen ab 65

 

Die Genauigkeit dieser Messungen muss natürlich stark (und zu Recht) bezweifelt werden. Die Ergebnisse wurden aufgrund weniger auswertbarer Nutzer aufgestellt und hochgerechnet. Dadurch entstehen selbstverständlich eingeschränkt repräsentative Zahlen. Aber immerhin…

Using the Exchange 2007 Web Service for Mail retrieval…

exchange07

So here’s the problem I had: There is an Exchange 2007 server I am forced to use for some of my daily work and that’s where the problems start: Due to the work of some evil geniuses there’s a load of user and security policies associated with that server. That’s not a problem per se: It’s just that things like “forward all mails to this account” don’t work. You have to use Outlook Web Access or the heavyweight Outlook to get to your mails… Till today I had an Outlook 2007 running on my private IMAP mailserver machine just for the purpose of downloading all the mail from the Exchange server to the local harddisk. I had setup a client-rule to copy all the mail to my IMAP server but despite the fact Outlook is running on the exact same machine as the IMAP server it just did not work for more than 1-20 messages… connections were lost and stuff screwed up. So I had to move all the messages manually (Select-All -> Drag-n-Drop onto the IMAP folder inside Outlook) which took me quite some time each month.

Two days ago I read an article where namenlos wrote about his journey with his employers Exchange server. He wrote a Python script that did the job for Exchange 2003 by using the WebDAV features. These features unfortunatly are deprecated in the current 2007 release of Exchange. So I decided to write a tool in C# that does the trick and uses the brand-spanking new Exchange 2007 Web Service.

The Exchange 2007 SDK is a wasteland to say the least when it comes to documentation. It took me some time and a good search engine to get to something useful out of it. But I think it’s worth the pain: When you got over the first annoying steps you’ll just like me will start to love the possibilities this Web Services give you.

In my case I am using the webservices to do these things:

  1. allocate my inbox and obtain a listing of messageIDs
  2. get the complete messages out of my inbox
  3. reformat the messages and send them via smtp to my own mail server

What I’ve written is not feature complete (as in: no attachements, …) but it’s a great and working start and does the 3 point-trick from above quite well. I will refine the code and add the missing features (e.g. attachements and stuff) in the future… or maybe you are faster than me. In that case it would be well appreciated if you send me your code/a link to the code (find my email in the sourcefile…)

the solution for the Windows Vista Event ID 4226 problem (TCP/IP security limit)

“Apparently in Windows Vista, Microsoft still enforce and hard-limit (hard coded in tcpip.sys) the maximum simultaneous half-open (incomplete) outbound TCP connection attempts per second that the system can make, as in Windows XP SP2, in order to protect the system from being used by malicious programs, such as viruses and worms, to spread to uninfected computers, or to launch distributed denial of service attack (DDoS). When the limit is hit, in Event Viewer, there will be such an entry:”

private space mission (the one with 20 megapixels…)

It just seems like make is going to get some interesting pictures tomorrow:

“We’re using weather balloons to go up to approximately 100k feet armed with 4 cameras… 20 megapixels of camera! We’ll be taking shots every 7 seconds for two hours and measuring the temperature with the Make: controller and thermistors!

It took 16 people working on this, countless cases of mountain dew, lots of take-out food, and a lot of sleepless nights, and we intend to fly Sunday!

Cloud cover, snow, and mechanical failure may postpone the launch, but we’re ready to give it our best shot this weekend.

In this Make: Video Podcast, you’ll learn all the details of how to put a weather balloon up into space! The weather balloon will make it up to about 100,000 feet. That’s almost 20 miles up and more than twice the height of being in an airplane. It’s high enough that the sky is black and you can see the curvature of the earth.”

So be sure to check back if you’re interested.

the 23c3 live streaming and recording plannings *ATTENTION: DRAFT!*

ATTENTION: The information in this article are not final and are subject to be changed during the plannings.

In less than 2 months the 23c3 takes place in Berlin/Germany (December 27.-30th 2006). And the plannings are in full progress. We had several brainstorm sessions and I think that we finally do have a plan. First of all: We learned a lot from the 22c3 live streaming and recording work. And to give you an overview of the things we want to achieve this time:

  1. permanent working live streams of all 4 lecture halls
  2. high quality recordings without using our DV-Tape fallback
  3. making low/mid/high quality recordings in different codecs available for download within 24 hours

To achieve these goals we’re going to need considerably more hardware than last year, which means:

  • 4 WMV Live Encoding machines
  • 1 MPEG-2 encoding machine with 4 MPEG-2 encoder cards
  • 4 video editing machines
  • 6 19″ TFTs + 1 4
  • at least 1 monitoring machine
  • more than 1 Tbyte of storage space
  • 5 cameras + 1 video mixer
  • a lot of helping hands (yes, we need help chaos angels!!)

So. The camera setup is almost identical to the last one. But this time we want to use a better FBAS signal instead of the in-house HF-cable-TV. The WMV encoding stays as it was last year. We plan to install an additional MPEG-2 hardware encoding machine which produces high-quality MPEG-2 data (which gets edited and compressed for download distribution as fast as possible).

Since we’re sill in planning stage we cannot speak about bitrates, live streams and such. Everything is subject to change, it’s just a draft. But stay tuned and read frequently. Oh… and comments are welcome.

Go,Go, Gadget-o-Power-Suit!!

Everybody will need one of these when the guardians attack zion…

“In 1990, we started to develop a Wearable Power Assist Suit, and in 1991 we fabricated a Powered Arm constructing the master and slave system in one unit by utilizing a rubber tube air actuator and sensing cuff, [ref. 1]. In 1994, we developed a Wearable Powered Suit constructed with powered arms, a powered waist, and powered legs [ref. 2], and finally in 2002, we developed a Stand Alone Type Wearable Power Assist Suit [ref. 3]. This suit was composed of newly developed air bag actuators driven by micro air pumps, newly developed muscle hardness sensors, and an embedded micro computer. The muscle hardness sensor was developed for detecting the muscle force driving joints. The micro computer was for calculation of the necessary joints torques to lift heavy objects. The calculation equations was derived by body mechanics. This suit could run continuously 20 minutes with 12 volts Ni-Cd portable batteries. The latest power assist suit can generate higher assist power, and is composed of compact body, a compact embedded micro computer, small and flat rotary sensors, and has newly designed muscle sensors which are embedded in 3-D mesh [ref. 4].”

switching to dvorak keyboard layout

Super Mario War…again

More than 2 years from now I wrote about Super Mario War. And now it’s time to take another look on the project and the upcoming version.

Super Mario War is a Super Mario multiplayer game. The goal is to stomp as many other Marios as possible to win the game. It’s a tribute to Nintendo and the game Mario War by Samuele Poletto. The game uses artwork and sounds from Nintendo games. We hope that this noncommercial fangame qualifies as fair use work. We just wanted to create this game to show how much we adore Nintendo’s characters and games.

Features:

  • Up to four players deathmatch fun
  • a whole bunch of game modes (featuring GetTheChicken, Domination, CTF, …)
  • Comes with the leveleditor – you can create your own maps…
  • … and a lot of people did so. There are currently over 400 maps
  • More fun than poking a monkey with a stick
  • The whole source code of the game is available
  • uses SDL and is fully portable to windows, linux, mac, …
  • CPU Players
  • will make you happy and gives you a fuzzy feeling

cracking galileo positioning system and talking about it…

The americans managed to crack…well they call it different but the fact remains that they cracked the PRN codes of the european global non-military positioning system called “Galileo

“Because GPS satellites, which were put into orbit by the Department of Defense, are funded by U.S. taxpayers, the signal is free — consumers need only purchase a receiver. Galileo, on the other hand, must make money to reimburse its investors — presumably by charging a fee for PRN codes.”

I guess… I guess I am wrong…


What happens when an API uses guessing to identify which character encoding is actually used in a text file:





  1. Open Notepad

  2. Type the text “this app can break” (without quotes)
  3. Save the file
  4. Re-open the file in Notepad


And the explanation: Notepad uses as windows system method called “IsTextUnicode()“. In the MSDN Library article on this method you can read:


“This function uses various statistical and deterministic methods to make its determination, under the control of flags passed in the lpi parameter. When the function returns, the results of such tests are reported using the same parameter.


The IS_TEXT_UNICODE_STATISTICS and IS_TEXT_UNICODE_REVERSE_STATISTICS tests use statistical analysis. These tests are not foolproof. The statistical tests assume certain amounts of variation between low and high bytes in a string, and some ASCII strings can slip through. For example, if lpBuffer indicates the ASCII string 0x41, 0x0A, 0x0D, 0x1D (A\n\r^Z), the string passes the IS_TEXT_UNICODE_STATISTICS test, although failure would be preferable. “


That simply means, that the method fails on detecting the correct character encoding. Aftermarket Pipes tells us:


“It actually runs a couple of heuristics over the first 256 bytes of the data and provides its best guess. As it turns out, these tests aren’t terribly reliable for very short ASCII strings that contain an even number of lower-case letters, like “this app can break”, “

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.”

the Super Mario Bros. hype continues…

It’s a real classic. It’s a great game and I am waiting for it’s newest incarnation: The New Super Mario Bros. for my also awaited Nintendo DS lite. Besides that: my apologies that the animated gif is 10 pixels wider than usually.

“Walljump is when you jump towards a wall and somehow Mario’s foot catches the wall
and allows to jump again, boosting from the wall. In the example image on the right, three walljumps are performed.

Theory: Walljump happens because the game does a floor check (a simple “is position divided by 16 even? Is there a solid block below him?” test) even during a wall-ejection. Wall-ejection is SMB’s mechanism to adjust Mario’s horizontal position properly when his left side and right side have a different inside-wall status. The game ejects Mario towards the opposite of his steering.”

To perform a walljump, you need two things:

  • Some horizontal speed (towards the wall)
  • Mario’s feet must hit the wall exactly at a block boundary (every 16 pixels)

It’s possible to perform walljump from any non-lethal solid material (bricks, pipes, etc).”

the quiet revolution

“An elegant vertical-axis wind turbine, quietrevolution has been designed and developed by XCO2, an established low-carbon energy consultancy and engineering practice.

Virtually silent and vibration free, quietrevolution is ideally suited to both urban sites and exposed locations.

The simple and robust design (patent pending) has just one moving part, maximising reliability and minimising maintenance requirements.”

Vertical-axis wind turbines not only look very sci-fi, but when you add LEDs to the border of the turbine you can use them as a display:

So I leave you with a patent pending revolution which produces power and is virtually silent…whatever that means.

a house demolition time lapse

Ralf of videobasics.de created a great time-lapse movie of a house demolition. See how things end:

Music by 2-RD. (I added this)

You can get the movie iPod-compatible via the muckefuck podcast feed.

Within some days there will be this and one more time-lapse movie be available on the streaming website of FeM e.V.. You can read here and of course on this site when it becomes available.

the illegal side of mathematics

I always knew that there is the bad taste of crime and the smell of illegality involved when it comes to mathematics…

“The first illegal prime to be announced, when interpreted a particular way, describes a computer program which bypasses copyright protection schemes on some DVDs. Because that program has been found illegal by courts in the United States of America, this has produced debate about whether the number itself could be considered illegal.”
