My SharpDevelop blog
Hey,
I have a SharpDevelop blog (http://community.sharpdevelop.net/blogs/marcueusebiu/) where I will post all my work regarding SharpDevelop.
Stay tunned!

Preview of Parallel call stacks pad in SharpDevelop
Hey,
I just finished a preview version on Parallel call stacks pad for SharpDevelop.
What do you think?

Parallel stacks and Common Stacks Algorithm
Hey,
For SharpDevelop I have created a version Parallel stacks. In this post I will present a algorithm that creates this Parallel stacks controls using "Common Stacks Algorithm".
Prerequisites: a debugger that gets you for every thread of the application it's call-stack;
SharpDevelop has a debugger that gives you for every thread of the debugged application it's call stack.
The Common Stacks Algorithms is like this:
1. For every thread, get it's call stack in ThreadStacks structure - just a class that contains the actual call-stack - and save them in some kind of list- List.
2. Get & Split common stacks
2.1. For all ThreadStacks, check if they have stack frames. If not, remove them from the list.
2.2 Get all call-stacks that start with the same stack-frame. This can be a Dictionary>.
2.3. For every group of ThreadStacks, find the place of split.
3. Create the common parent ThreadStack and clear the group of common stack-frames.
4. Link the parent to the children and children to parent.
5. Update the collection of ThreadStacks
6. Repeat from 1, until no split is possible - all are parents or simple leaves = the list of common stacks contains only 1 ThreadStack.
What do you think? Pretty nice!
For an implementation, see my Parallel branch in my github.
Happy coding!

SharpDevelop improvements(2): Pinned data-tips
Hey everybody,
I've developed a data-pins version in SharpDevelop IDE. See my github for implementation.
You can:
- add a data pin with variables
- refresh data inside pins
- save and load data pins
- move pin grid independent of the pin location and pin location independent of pin grid - this is not supported in VS 2010
- add comment to a data pin.

SharpDevelop improvements(1)
Hey everybody,
SharpDevelop is at 4.1 pre-alpha and some of my contributions are inside.
These are:
- WPF breakpoints pad with code completion
- WPF bookmark pad
- WPF watch pad with code completion
- WPF local vars pad
- change Reflector path in Options panels.
- spell checker based on (N)hunspell - this addin is not inside the release but you can find it on my github.
The next improvements concerns pin data tips and edit value in debug tooltips.
Give #D a try! :)
Happy programming!

My SharpDevelop wish list
1. Parallel Tasks window/pad
2. Parallel Stacks window/pad
3. Format code on save(C#, VB, X(A)ML,)
5. IntelliTrace
I'll add others in the future...
Create Git new remote branch script
if [ $# -ne 1 ]; then
echo 1>&2 Usage: $0 branch_name
exit 127
fi
branch_name=$1
git push origin master:refs/heads/$branch_name
echo "git push origin master:refs/heads/$branch_name"
git fetch origin
git checkout --track -b $branch_name origin/$branch_name
git pull

Disassemble and assemble .NET files
Hey,
Today I wanted to edit some resources in some .NET assembly. For that I used ildasm, Resourcer and ilasm tools.
Step 1. disassemble: ildasm /out=assembly_name.il assembly_name.dll
This will output the il file and the resources.
Step 2. edit resources with Resourcer.
Step 3. assemble the result:
ilasm assembly_name.il /dll /resource:asssembly_name.res /output=assembly_name.dll
This order is important. Otherwise you will get some errors like "Could not create output file, error code=0x80004005".

SharpDevelop Ideas
Hey...
I started playing/developing with SharpDevelop IDE and I made/proposed some very nice changes:
- expand regions with double click - implemented with the help of Daniel Grunwald
- drag and drop current yellow line in debugger - implemented with the help of Daniel
- focus/select the member in the combo in editor
- update position of completion window - implemented with the help of Daniel
- tooltip for folding elements - implemented with the help of Daniel
- remove all breakpoints
- remove project from recent list
- watchpad features + code completion when adding a watch variable - implemented with the help of Daniel Grunwald
- partial fix for x:Name in XAML
- search for type names in Add Reference window - with some suggestions for using Mono.Cecil from Daniel
- fix some issues.
Now I'm working on a spell checker... :D
Check #D out! It's very cool! :)
Spell checker
Hey all...
Today I found a very nice "tool" for spell checking. It is called hunspell and it looks like it is used by major applications like OppenOffice, Mozilla Firefox, Google Chrome, Opera, etc. It's using OpenOffice dictionaries...
Very nice and easy to use...
Happy coding!

Run/Execute EVERYTHING in the cloud
Hey there...
Image this... everything runs/executes inside the cloud... you can read/update your documents from a web page (I know, Google Docs or Office live)... read/update pdf documents... play games (I mean games like... Age of Empires, Half life... etc)... copy/save files from the web (images, docs, you name it...)... or even develop apps (using your preferred IDE).
All this without having any data on your hard drive... of course, if you want to have data on your drive, it's your choice...
Won't this be perfect? :)
[For those who have ears to listen...]

Connection between human senses and file formats
Hi there...
where n is the number of senses. For humans, there are 2^5 - 1 = 31 formats.Humans have 5 basics senses: sight, hearing, taste, smell and touch.
If we think at file formats that we can interact, are using only a part of them. In general, files are divided as: text, images, waves and movies (moving images with sound).
With text and images we are using only sight; with movies we are using sight and hearing.
Let's see how many formats can exist for our senses. We basically all senses apart, all senses grouped in 2, in 3, in 4 and all together. The formula for this is:
Now, we only know 4 of them!!!
What's the next one? :)
