Simple Sysexxer receiving data
During the last days and weeks, I missed some minor features in Simple Sysexxer, so guess what I was doing…

Simple Sysexxer: »Eat your own dogfood!«
Wednesday, February 3rd, 2010JOSM Presets updated

JOSM Logo
I rearranged the presets in JOSM and am prepared for the usual bashing :) .
Tracks and paths have been reunified into one menu entry only, so the convenience menu shortcuts to the various types of tracks and paths are past. OTOH, I have introduced dedicated menu entries for combined foot and cycleways:
JOSM presets - cleanup and additions
The types have been included as popup menus into the dialogs. Besides tracktypes and hiking scales, I also included mountainbike scales, while more special tags for mountain bikers can be used by including an existing set of externally maintained presets:
JOSM - Path Preset
Obviously, the dialogs are completely overcrowded. We will not be able to stuff any and all tags that will develop in the future into JOSM. Be prepared that I will do some major cleanup work some day.
External Presets in JOSM
Sunday, January 17th, 2010JOSM Logo
JOSM provides the capability to include presets from external sources. It is the perfect mechanism for a group of mappers to maintain a specialized set of presets. This way, »Special Interest« mappers like skiers, mountain bikers or seamen can feed menu entries they need directly into JOSM without polluting the default menu space of JOSM.
Some examples are available via JOSM’s wiki pages. There’s also a page how to create and use such presets.
Sorting Sound Files using Ruby
Wednesday, November 25th, 2009
Consider you have 2,248 files in a directory, each containing one single sound program for your favourite Z1 synth. You need to load them into the synth individually, listen to them and to sort them in directories. Painful it would be.
Fortunately, all sounds are set to one of 18 predefined categories like guitar, synth hard, synth soft, piano, organ and the like. In the SysEx files, the category is coded into the 26. byte. So it was easy to sort the files into subdirectories using a couple of lines of Ruby code (sorry for the misformatting):
#! /usr/bin/ruby
require 'fileutils.rb'
def determineCategory( filename )
file = File.open( filename, "rb:binary" )
fileContents = file.read
category = fileContents[25] + 1
# puts filename, category
unless File.directory?(category.to_s)
Dir.mkdir( category.to_s )
end
FileUtils.mv( filename, category.to_s )
end
Dir.glob( '*.[Ss][Yy][Xx]' ) do |entry|
determineCategory entry
end
This language seems to be very powerful. Need to do more with it.
XP Days Germany ahead
Wednesday, November 25th, 2009
Meeting Point Symbol (openclipart.org, public domain)
The XP Days are just a couple of hours ahead. I’m curious what people will attend and expect some illuminative talks. I hope it will be possible to blog directly from the conference, either using the notebook or the N810. I’ve also set up an “extra group” :) in our “company owned” messaging system in advance.
Though it is not for free it was too tempting to attend – it’s just a five minutes walk from our office, so there was no excuse :) .
ALSA Sequencer Interface for Simple Sysexxer

Simple Sysexxer Icon
The last release of Simple Sysexxer used RtMidi for MIDI input. However, some weird things happend when I tried to receive data from my beloved Korg Z1 synth. Today I have rewritten the MIDI input thread using the ALSA sequencer API.

Expense-Recorder released

Expense Recorder
Admittedly, it’s just a modification of the Waypoint Catcher. For me it’s useful anyway :) .
Ruby on Rails on the Nokia N810 – sqlite lib needed
Thursday, September 17th, 2009I’m currently playing with Ruby on Rails, just for my very own pleasure and joy. Admittedly, that’s only one half of the truth. Some ruby (respectively rails) knowledge will also help me during my “daytime job”. What I’d like to do for now is to develop some rails application for the Nokia N810.

Subgroups in JOSM presets
Tuesday, September 15th, 2009The presets in JOSM are built at runtime parsing an XML file. JOSM gets shipped with one default file which I usually maintain. Users beg for the inclusion of further features regularly, so meanwhile the menus as well as the dialogs are both densely populated. This makes JOSM hard to use on devices with smaller displays, like the popular Netbooks or internet tablets.

JOSM presets - Museum
JOSM, an openstreetmap editor written in the Java programming language, provides some “presets” which allow the user to tag objects easily just by selecting it from a menu. This menu and the corresponding dialogs are all defined in a huge XML file, presets.xml. It allows to define menu entries, subgroups and finally dialogs with standard GUI controls such as checkboxes, comboboxes, line edits, labels, icons etc.
The aforementioned presets.xml is included in josm.jar, but JOSM even can load such presets over a networking connection (http). This makes it easy for users to create and use their very own presets, maybe for specialized use cases like event mapping, mapping ski pistes or nautical stuff.
On request, I have just added the tag “opening_hours” to various presets like shops, restaurants, museums and the like:
JOSM presets - Museum Dialog
If you have further requests, do not hesitate to open a trac ticket. It’s even possible to do this as anonymous user, so there’s no excuse :) .
Simple Sysexxer 0.2 beta released

Simple Sysexxer 0.2
I have just released Simple Sysexxer 0.2 beta. See its dedicated page on this blog for details about download and usage.
I need feedback how it works with various flavours of MIDI instruments. If you can share success stories, bug reports or even feature requests, please let me know.
Simple Sysexxer Source added to Sourceforge SVN
Tuesday, August 18th, 2009I have just imported the current source code of Simple Sysexxer into Sourceforge’s SVN server. To grab your copy, just use the following command:
svn co https://sysexxer.svn.sourceforge.net/svnroot/sysexxer/
Additionally, sysexxer.sf.net now redirects to the Simple Sysexxer page on this blog.
Simple Sysexxer 0.2 Beta available
Monday, August 10th, 2009
Simple Sysexxer 0.2 Beta
I just sent out an electronic message to various people who hopefully won’t be able to detect any bugs :) . If you like to help with testing, please do not hesitate to drop me a line. If no major issues occur, I’m inclined to release it before the end of this week.
Details about it can be found at it’s dedicated page of this blog.
Adding Drag’n'Drop-Support to a QT4 application
Sunday, August 9th, 2009While working on Simple Sysexxer, I wished to add drag’n'drop support to open files. Thanks to QT4 it was quite simple. The following code has basically been derived from the book C++ GUI Programming with Qt4 and slightly modified to fit into the existing code.
