1. image 1
2. company image
3. image 2
4. company image
5. image 3
6. company image
7. …

I wanted to do this without writing a program or installing Perl (his laptop is a Windows box) so I did this with a tiny Windows batch file:

@ECHO OFF
setLocal EnableDelayedExpansion

SET count=1
SET IMAGEDIR=%1
SET FILLIMAGE=%2

cd %IMAGEDIR%
FOR %%a IN (*.*) DO ( call :do "%%a" )
GOTO :EOF

:do
SET UQ1=%1
ren %UQ1% "%count%_!UQ1:"=!"
set /a count+=1
copy %FILLIMAGE% "%count%.jpg"
set /a count+=1
GOTO :eof

Given the batchfile slideshow.bat, the directory with a copy of all the source images in C:\images and the company logo image in C:\companyimage.jpg the call simply is:

slideshow.bat "C:\images\" "C:\companyimage.jpg"

This will rename all the pictures found in C:\images with a number in front of the original file name – with one number left out; like 1,3,5,7,etc. The company image is copied in between all these images as 2.jpg, 4.jpg, 6.jpg, etc. Now simply viewing the first image with Windows Picture Viewer and hitting the slideshow button will display the files by name which is exactly the desired display order.

Regarding the batchfile: it would be possible to execute multiple statements within the DO ( … ) but that way the counter variable did not work. I had to do a call to a method which then changes the counter. Another issue was the unquoting of the file name. The “%%a” supplies the image file name with double quotes to the %1 inside the :do function. As the final name should be counter + image-name without unquoting it would look like 1_”my image.jpg” which will do an error. The magick is the !VAR:”=! which unquotes the string in VAR.

Most of the time we use these devices for testing our mobile websites and to find out how the rest of the mobile world does it. As I’m not that in favour of spending so much money for an Apple phone I ordered a startup Android 2.1 phone some time ago. The actual Huawei-manufactured Vodafone 845 comes with a pretty small resistive 320×240 pixel display – but: hey, it came only 100€!

After trying many many apps the following list is an overview of my favorite ones. I might add a list pretty useful iOS apps in another article together with Benjamin in the next days.

The scumm VM is a virtual machine for the best adventure games ever – created some years ago by Lucas Arts. Till now I could only find a very early ported version for android but following the instructions in the website at: http://sites.google.com/site/scummvmandroid/ I got the manually installed apk running. You’ll need some files from the scumm VM project (datafiles) – just stick to their FAQ and it should work.

You can get some of the old games from abandonware games website on the web or just copy the data from your 3.5″ floopy disks . I successfully played Monkey Island 1 + 2, Zak McKraken, Sam & Max and Day Of the Tentacle (though the sound is sometimes cracking).

By the way: I used the QR Code generator by Jason Delport of Paxmodept to create the QR codes. You can get market links and package names of android apps using androlib.com and – as of today, I believe – you can visit the market links using any browser as google opened the market for the web.

<script type="text/javascript">

window._oldTimeOut = window.setTimeout;
window.setTimeout = function(execute, timeout) {
  var id = window._oldTimeOut(execute, timeout);
  console.debug("created timer with id:", id, arguments.callee.caller.toString());
  console.debug('execute',execute.toString());
  return id;
};

window._oldInterval = window.setInterval;
window.setInterval = function(execute, timeout) {
  var id = window._oldInterval(execute, timeout);
  console.debug("created interval with id:", id, arguments.callee.caller.toString());
  console.debug('execute',execute.toString());
  return id;
};

</script>

This gave me at least a hint where the sourcecode lines of the timer-executed code can be found. Also very helpful is a stack trace (aka call stack) at the current code position to find out which other function was calling the current one. I found a pretty old but still working code snippet on http://helephant.com/2007/05/diy-javascript-stack-trace/ and added it to my timer debugging:

<script type="text/javascript">

Function.prototype.trace = function() {
 var trace = [];
 var current = this;
 while(current) {
 trace.push(current.signature());
  current = current.caller;
 }
 return trace;
};

Function.prototype.signature = function() {
 var signature = {
  name: this.getName(),
  params: [],
  toString: function() {
   var params = this.params.length > 0 ?  "'" + this.params.join("', '") + "'" : "";
   return this.name + "(" + params + ")";
  }
 };
 if(this.arguments) {
  for(var x=0; x<this.arguments.length; x++)
   signature.params.push(this.arguments[x]);
 }
 return signature;
};

Function.prototype.getName = function() {
 if(this.name)
  return this.name;
 var definition = this.toString().split("\n")[0];
 var exp = /^function ([^\s(]+).+/;
 if(exp.test(definition))
  return definition.split("\n")[0].replace(exp, "$1") || "anonymous";
 return "anonymous";
};

window._oldTimeOut = window.setTimeout;
window.setTimeout = function(execute, timeout) {
 var id = window._oldTimeOut(execute, timeout);
 console.debug("created timer with id:", id);
 console.debug('execute',execute.toString());
 console.debug("stacktrace", arguments.callee.trace());
 return id;
};

window._oldInterval = window.setInterval;
window.setInterval = function(execute, timeout) {
 var id = window._oldInterval(execute, timeout);
 console.debug("created interval with id:", id);
 console.debug('execute',execute.toString());
 console.debug("stacktrace", arguments.callee.trace());
 return id;
};

</script>

Be sure to add that script tag at the very top of your JavaScript execution (as the first element of your <head> tag for example).

find . -iname '*.css' -o -iname '*.html' -o -iname '*.js' -o -iname '*.pm' -o -iname '*.pl' -o -iname '*.xml' | xargs grep -rl $'\xEF\xBB\xBF'

To remove the BOM I followed the suggested way by http://stackoverflow.com/questions/204765/elegant-way-to-search-for-utf-8-files-with-bom using sed:

find . -iname '*.css' -o -iname '*.html' -o -iname '*.js' -o -iname '*.pm' -o -iname '*.pl' -o -iname '*.xml' -exec sed 's/^\xEF\xBB\xBF//' -i.bak {} \; -exec rm {}.bak \;

Tada, no more ugly BOMs!

FOR /F "tokens=*" %%G IN ('dir /s /b *.png') DO optipng -nc -nb -o7 -full %%G

The optipng params -nc and -nb prevent any color and color depth changes of the png files. Those may change the appearance, for example in the evil Internet Explorer. -o7 means the best and slowest optimization and -full does a full scan of the IDAT part. Using UNIX the same job may look like:

find . -name *.png | xargs optipng -nc -nb -o7 -full

Autopano Giga and HDRs

The “Giga” version of Autopano supports working with multiple exposure series. So my first idea is to just apply the Autopano workflow to all the pictures that will belong to the panorama. There’re 12 pictures in my case and Autopano automatically sorts them into 4 panorama parts (4 views á 3 different exposure times).

Now I just apply the detection and change to the editing mode of the resulting panorama. There I choose not to apply any color correction (I want to tone map the HDR later anyway) plus I crop the borders. Notice the layer setting to output only one blended layer.

Now I just render the panorama with one target .hdr file.

So far so good. Next I open the hdr file I just created in Photomatix to do some tone mapping, but what’s this?

Seems like this does not work the way I want to. There’re many ugly blending errors and the light spots are all overspilled!

The workaround

Ok, back to Autopano’s edit panorama mode. In the layer section I now chose “Group by speed” as I want to get a separate panorama image for each exposure serial, but with exactly the same panorama stitching (the three panoramas have to match each other exactly, otherwise the later HDR generation in Photomatix would screw up the .hdr entirely).

Now again I render the panorama but not targeting one .hdr file. Instead I choose the 8Bits TIFF format. To get one TIFF per exposure serial I have to add a “%L” to the file name for the layer name.

Great, after exporting I get three TIFF images with the stitched panorama for each exposure serial.

HDR generation & tone mapping

The next step is as simple as I is with non-panoramic pictures. I just create a new panorama in Photomatix and deactivate the alignment tool (the panorama, taken using a tripod, is already aligned) and activate the ghost reduction for objects and people (this happens quite often with exposures lower than 5 seconds). Really important is to activate the noise reduction – otherwise the hdr will look like a Christmas tree. Finally, after applying the tone mapping and doing some little fixes in GIMP (sharpen, denoise, contrast), it’s a nice HDR panorama.

But when exporting/printing to a PDF file the PDF document in Acrobat Reader shows only a single page at a time. One may manually select the view option with two-paged layout and flyleaf but I wanted the document to be always shown that way! After Googling I found a solution using Adobe Acrobat Pro where it is possible to set this option and save the changes directly to the PDF file. Unfortunately Acrobat Pro isn’t cheap and I don’t own a copy so I looked for an alternative.

Finally I found BeCyPDFMetaEdit by Benjamin Bentmann which is a small freeware Windows utility for changing the XMP meta data of a PDF document file. The viewer preference  actually is just a XMP setting. The program can remove any application or pdf printer metadata as well (like “Created with …foo program” or “Printed using PDF…bar”). The result after opening the PDF document in Adobe Acrobat Reader then looks like (before vs. after):

Ta-da, A book!

@echo off
SETLOCAL
set WEBSITES=Test1 Test2 Test3

FOR /D %%A IN (%WEBSITES%) DO (
 echo WebsiteName=%%A
)
GOTO :EOF

ENDLOCAL

and in Linux shell:

WEBSITES="Test1 Test2 Test3"

for WEBSITE_ALIAS in $WEBSITES ; do
 echo "Website= $WEBSITE_ALIAS ..."
done

But now came a second list of string into play containing the domain names of the website aliases:

WEBSITES="Test1 Test2 Test3"
DOMAINNAMES="www.test1.lan www.test2.lan www.test3.lan"

In a conventional programming language I would just use a for-loop with an index variable and utilize that variable to access both arrays within one loop. But in that batch/shell scripting this turned out to be quite tricky. My solution here was a small inline PERL script. For Windows:

set WEBSITE_UNIT=Unit4
set WEBSITES=Test1 Test2 Test3
set DOMAINNAMES=www.test1.lan www.test2.lan www.test3.lan
perl -e "use strict; die(\"argv mismatch!\") if !@ARGV or scalar(@ARGV) < 2; my @Websites = split(/[\s,;\|]/, $ARGV[0]); my @Domains = split(/[\s,;\|]/, $ARGV[1]); die(\"number of aliases differs from domain names!\") if scalar(@Websites) != scalar(@Domains); for(my $i=0; $i<scalar(@Websites); $i++) { system('perl dosomething.pl -user /Root/'.$ENV{'WEBSITE_UNIT'}.'/admin -passwd admin -servername '.$ENV{'SERVER_NAME'}.' -alias '.$Website[$i].''); system('perl doanotherthing.pl -user /Root/'.$ENV{'WEBSITE_UNIT'}.'/admin -passwd admin -alias '.$Website[$i].' DomainName=\"'.$Domains[$i].'\"'); }" "%WEBSITES%" "%DOMAINNAMES%"

And for Linux:

WEBSITE_UNIT=Unit4
WEBSITES="Test1 Test2 Test3"
DOMAINNAMES="www.test1.lan www.test2.lan www.test3.lan"
perl -e 'use strict; die("argv mismatch!") if !@ARGV or scalar(@ARGV) < 2; my @Websites = split(/[\s,;\|]/, $ARGV[0]); my @Domains = split(/[\s,;\|]/, $ARGV[1]); die("number of aliases differs from domain names!") if scalar(@Websites) != scalar(@Domains); for(my $i=0; $i<scalar(@Websites); $i++) { system("perl dosomething.pl -user /Root/'${WEBSITE_UNIT}'/admin -passwd admin -servername ".$ENV{"SERVER_NAME"}." -alias ".$Website[$i].""); system("perl doanotherthing.pl -user /Root/'${WEBSITE_UNIT}'/admin -passwd admin -alias ".$Website[$i]." DomainName=\"".$Domains[$i]."\"");  }' "$WEBSITES" "$DOMAINNAMES"

Notice the different handling of the ticks and quotes and the different access to external parameters. In Windows there’s no difference in PERL’s $ENV hash whether accessing real environment variables or local variables set by the batch script. Not so under Linux: I can only access my system-wide exported environment variable SERVER_NAME using $ENV but not my local script’s WEBSITE_UNIT variable. When using the exec -e with perl for Windows I had to use quotes to wrap the execution PERL-code but for linux shell, I needed single ‘-ticks which can NOT be used inside the PERL code – not event when escapting them like \’. The single ticks are “reserved” by the shell script for being able to insert shell variables anywhere.

set nowrap

You can also do this when starting nano:

nano -w <file>

Obviously I only posess the 18-55mm Kit lens and I use smaller focal lenths more often. The Google chart API is quite handy for such simple statistics.

Build:
javac -Xlint:unchecked -classpath .;metadata-extractor-2.4.0-beta-1.jar FocalApp.java
jar cfm FocalApp.jar Manifest.txt *.class

Usage:
java -jar FocalApp.jar [Options]

Description:
For all images in the given directory and its subdirectories read the
lenses' focal length from the exif data and print a summary of how
often the particular focal lengths are used.

Currently this program works with the following image types:
* JPEG
* CRW - Canon Raw
* CR2 - Canon Raw v2
* NEF - Nikon Raw
* ARW - Sony Raw
* TIF/TIFF

Options:
-imagepath          path for the images to work on                          (required)
-camera             string with the name of the camera, the program will    (optional)
only count the images containing that camera name
-fileext            only count images with that file extension(s)           (optional)
-filename           only count images matching this regular expression      (optional)

Examples:
java -jar FocalApp.jar -imagedir "D:\testimages"
java -jar FocalApp.jar -imagedir "D:\testimages" -camera "Canon EOS 30D"
-fileext "jpg,crw" -filename "^CRW(.*)"

Feel free to get the new version here. You can find the original blog post to the FocalApp here.

Believe it or not, this was quite a challenge. I tried to use precedent and subsequente regular expressions in UltraEdit for this but UltraEdit’s regex is quite dumb. So I came up with good-old shell:

find . -name "*html" | xargs grep -l 'StringA' | xargs grep -L 'StringB'

Beginning from the current directory (“find .”) this finds all html files containing the string ‘StringA’ in the first grep statement but NOT the ones containing the string ‘StringB’ in the second grep statement. If any nerd could tell me how to do this more easily, this would bring light in my day-to-day life. Actually this shell piping is pretty fast. I ran this over hundreds of html files in half of a second. Using PERL you’d need 30 lines and half an hour, I think.

To do this in Windows, you’ll need gfind, xargs and GNU grep (see UnxUtils website)

I used JDK 1.6. To build, you’ll need the “metadata-extractor-2.4.0-beta-1.jar” from the metadata extractor page. Then use:

javac -Xlint:unchecked -classpath .;metadata-extractor-2.4.0-beta-1.jar FocalApp.java
jar cfm FocalApp.jar Manifest.txt *.class

to build it. The Manifest.txt is just for entry method:

Manifest-Version: 1.0
Created-By: 1.6.0 (Sun Microsystems Inc.)
Class-Path: metadata-extractor-2.4.0-beta-1.jar
Main-Class: FocalApp

The run the jar, i.e. using:

java -jar FocalApp.jar "/path/to/your/images"

A tricky construct I had to google for after all the java-free months was how to sort a TreeMap by its values and not by the keys. In PERL this is simple (see Perlfaq4 for example):

my @keys = sort { $hash{$a} <=> $hash{$b} } keys %hash;

You get an array containig the hash’s keys, but sorted in the order of the hash’s values.
Now you can just iterate over the keys, displaying the values which could be something like that:

foreach my $Key (@keys) {
  print "Key $Key has value $hash{$Key}";
}

In java I couldn’t find such an easy solution. First, I use a TreeMap to store the key-value pairs. This can already sort by keys using a SortedMap. But to turn the sorting around I needed put the entire content of that SortedMap into a TreeSet collection (code line 78), which uses a custom Comperator instance. I got this snippet from this forum page.

You can download the java code in a zip from here.
