I’ve thought that I was done writing this kind of stuff, but I’m about to tell you something amazingly simple and yet very cool.
Just go to:
System Preferences -> Keyboard -> Keyboard Shortcuts -> Services – that’s it.
There’s a hell lot awesome stuff you can do here.
Just remember to pick up a key modifier that would not interact with other apps. Command + Control is quite a good choice.
Here’s a bunch of cool stuff that I did:
1. Open an address in Google Maps [ ^ ⌘ G ]
This is minor but possibly time saving.
2. Import image [ ^ ⌘ O ]
This is really useful – importing photos from iPhone straight to a document/note
3. Capture selection from screen [ ^ ⌘ P ]
Complementary to the previous tip – you can capture part of the screen directly.
4. Send to Kindle [ ^ ⌘ K ]
I often choose to read things on Kindle instead of a lcd screen, this tip just reduces the number of clicks between Kindle and my laptop. Note: You need Send to Kindle app installed in order to use it.
5. Upload with CloudApp [ ^ ⌘ U ]
Instead of dragging why not just use a keyboard shortcut? Note. You need Cloud App .
6. Look Up in Dictionary [ ^ ⌘ D ]
This is actually cooler than I thought. You can translate stuff just by putting the cursor over them, even in system windows!
Major relief from clicking.
8. Typeset LaTeX Maths Inline [ ^ ⌘ M ]
I’ve left the coolest for the end – this let’s you change a LaTeX text into a nicely rendered picture in apps like Evernote – very useful for making science notes. Note. You need to download LaTeXian and change it’s default format from PDF to PNG.
And that’s just what I’ve discovered, what will you come up with?

Sometime ago I saw a TedTalk done by Mr. Daniel Wolpert, which now (once I’ve watched it again) made an even deeper impression on me; The bayesian predictions and the feedback loops are surely something worth thinking about, but the first time I’ve watched it I’ve became instantly occupied with one of the very first sentences he said, paraphrasing: “The brain exists in the first place to produce motions.” (1)
This thought surely stirred a lot of thinking in me and at first I wasn’t in perfect agreement with it either, but gradually over time I’ve become accustomed to this thought and now I can point a lot of other clues that happen to fit well with it.
Let me give you one example – Recently on TED I saw another TedTalk (which I can’t get a direct link to) in which Mr. Joshua Foer talks about his research on developing amazing memory. He postulates convincingly that our memory capabilities can be extended using our imagination. He even goes on to present some evidence, in which they’ve put both; normal people and the memory savants into an fMRI machine while in the process of remembering and it turns out that the only difference between them was that the memory savants tended to use their spatial memory and navigation areas of the brain… Ehm, sorry, what did you say again? Correct, spatial and navigational areas of the brain. It turns out that we have an exceptional spatial memory. Mr. Foer goes on bringing up ancient orators using the spatial technique and old linguistic analogies to places. The question he asked himself was whether he could perform the same after some training – the answer turned out to be ‘yes’. We can train our minds to pay attention and remember, by recalling the ancient strategies that seem to be forgotten in the era of quick internet access, remainders and flash memory drives.
You may ask what are those strategies precisely doing – are they creating abstract worlds in which we can perform our imaginary walks? It seems so, and in the context of (1) it seems that our brains are just building upon what’s already there, borrowing the method. In other words we’re just looking at the work of the good old patchy-evolution, which tends to translate facts into something the navigating brain can understand and move between – space of events.
Now I’d like to tell you about something that lately occurred to me. This hypothesis may not turn out entirely new ( or true : ) ), but a discussion in the comments would be very welcome.
What if our effectiveness at Mathematics depends on similar strategies, which tend to make our ways of thinking a little more synesthetic?
Mathematics is a universe. Mathematicians are the pioniers, the explorers of new and unknown before. Then, eventually, the paths become so common that they become widely known by many.
One may now think: Wouldn’t it be wonderful if we could come up with a mathematical proof, simply by thinking about a way of getting to a specific point in space? An analogy of saying ‘go straight, then turn right, climb the stairs’…
In the first part of this article we’ve been talking about remembering things that didn’t necessarily have any predefined relation to each other. Mr. Foer taught us how to remember things by using made up connections to create a palace over which we could walk through the eyes of our imagination and amuse ourselves.
Mathematics doesn’t give us that much freedom, it constrains us, in similar fashion that the reality does. While the memory palaces created on Memory Contests are goofy and arbitrary, the palaces of Mathematics need to be ones of fine structure, not connected in arbitrary fashion. Therefore Mathematics is about discovering bridges between islands and describing their properties (is it a one way bridge? does the bridge lead to a parent island or to child island) instead of creating them. Sometimes you even have to stop and decide whether you’ve landed on the same island or a new one.
Of course making up a connection is easier than actually finding out what the connection is, but hey – that’s Math, an activity for real man. How could we get better at it? This was a question I’ve asked myself and I came up with a few proposals:
- Think about the types of possible connections between structures and compare them with the ones defined already in math (injection, surjection, morphisms etc.)
- Try to get a good mental picture of each of them, try to associate a color/smell/feeling with each one. Perhaps the relations relate somehow to each other – try to take that into account too.
- Train logic interference – that is, the speed and accuracy of the evaluation of logic statements (I’m planning to create an app for this during the weekend, but in meantime you can take a look on this cambridge test which provides one test similar to what I’m about to implement)
- Translate mathematical objects into space events and use the relations to connect them together building a Math Palace, then take a hike around the place.
In case of memory, Mr. Foer showed us that we can build highways in places where fragile country roads had been. I don’t know how far we can stretch that intuition, but nevertheless I found it worthwhile to think about.
Here’s a bonus thought: Doing Physics requires somehow an inverse process.
It’s process of finding the right structures from the mathematical universe and trying to fit them to the structures of the real world.
Feel free to argue with me in the comments below.
[Edit: 6 May 2012 16:32]
While planning the inner workings of the new app I’ve started researching the topic on pubmed and found some research that seem to back up my hypothesis:
“…results of the present study imply that the neural substrate, which is potentially necessary to enhance specific skills dramatically by positively motivated excessive mental training, might be present in every healthy individual.”
[Edit: 9 May 2012 13:48]
I’ve just finished reading Joshua Foer’s book ‘Moonwalking with Einstein’ and I must say that while I had moments of feeling towards discarding this book as completely invaluable, it would be unreasonable to do so.
However, I should warn everyone that saw his TedTalk that he doesn’t in fact use the memory techniques that he so much promoted on the TedTalk, instead in his book he just promotes mindfulness.
His book doesn’t contain any kind of special recipe for improving everyday memory, instead it leaves open questions, describes the history of memory improvement, savants, the process of mastering a skill (worth reading) and his own experience at the memory contest.
That story leaves yet another doubt to how much we can improve ourselves and to the validity of my hypothesis.

The following quote captures the essence of Aristotle’s philosophy and uncovers a lot of motivation behind my new iOS app called Systematic.
However the real source of motivation to create this app has been my year long stay in Valencia (Spain), where more then ever before have I learned about the benefits of a well balanced life.
Not only did the balance get me more productive, but it also got me much more relaxed.
However getting to this wonderful point of balance took my about 3/4 of a year in Spain. So I’ve begin to wonder how could I speed up the whole process. How do I free myself from procrastination? Perhaps with some kind of system that would help keeping life well balanced?
Could one of the old systems be used to get to a more balanced life?
- No, calendars are too rigid for this new purpose.
- Calendars are useful for things that you must do, at a certain hour like work, lectures or meetings.
- No, reminders need constant attention and are annoying if not set to the right hour.
- Reminders are useful for things that you need to remember.
- No, todo lists do not repeat the task over periods of time.
- Todo lists are good for keeping a list of task connected with a certain project.
So I’ve needed to develop my own application.
An app that would keep track of the tasks that you want to do repeatedly and suggest them at the right moment.
I’m really glad with how the app turned out as it’s extremely helpful for me for a bunch of reasons:
- I don’t get overwhelmed by the number of tasks I need to accomplish.
- It doesn’t tell me “Do X now”, it tells me “Hey, here’s a bunch of things you could be doing right now ordered by the ones most neglected”.
- I don’t need to keep track of all the things in my head.
- I know that even if I don’t get everything done perfectly, after some time I’ll get more efficient and do things better.
Although I already have a roadmap till version 1.1, I’m open for suggestions!
Tell me what functionality in your opinion is missing or what you’d change.
Enjoy a better life with Systematic. :)

After writing a 3d engine with Gouraud shading and per vertex Phong lightning model, which was the basis of evaluation of the graphics course, I’ve decided to do something more.
The topic was influenced by Dr. Eng. Martin Tabakow, who proposed visualizing volume information using 2D tomography scans data, segmented previously using his own algorithm.
I’ve been thinking a lot about how it could be done effectively, considering such ideas such as vertex representation using spline interpolation or adaptive surface tessellation, but after some searching and long discussions with Rychu (who is also my best personal debugger and saved me a lot of hours :) ) I’ve decided to use Voxels with ray-casting as display method. After getting the basic version to work properly, I’ve added trilinear interpolation, per voxel shading and deeper raycasting (a bit slower) for getting the looks closer to those from marching cubes.
So at the end, the application takes a the segmented data, analysis it, makes interpolation in between and at the end, calulates normals accordingly to the neighboring voxels and light using Lambertian light model with attenuation. At display I’m using Smith’s cube intersection algorithm to determine the intersection points of the ray with the volume data. Then I interpolate from one point to another searching for the first non-null element and display it.
Here is the example input data:
And here are some sample results:
The application allows to move it freely and to switch from one mode to another, yet there are some things that I’d like to improve in future like a better interpolation shape and smoother edges, but maybe after some recovery from the ‘Java experience’.

Today I announce the first alpha version of External Lightmapping Tool that works not only with 3dsmax and Windows, but now also with Maya and Mac OSX.
So far the system was tested on Windows 7 and Mac OSX Snow Leopard with Maya 2010. The package can be downloaded from here:
How to use it?
1. Run a Unity project on which you’d like to use it, then open elt_maya.unitypackage
2. Open External Lightmapping Tool window (menu Window in Unity)
3. Point where the Maya application is installed and add objects to lightmap list and some lights to unity scene
4. Export scene (Maya should open)
More info how to use it can be found here: https://masteranza.wordpress.com/unity/lightmapping/
The system works, but I’m not a Mac user neither Maya user, so I would like to hear suggestions from you, especially when it comes to render quality in Maya using BakeSets.
I would like to make it produce as high quality renderers as it can without tedious user preconfiguration.

It’s been a while since the first post about the lightmapping tool (even the name evolved to a more general one ;)) and I handed out the system to Unity a week ago. Now the mentors are making from it a neat package and adding some example assets and I myself am making the documentation better and trying some weird stuff to make the system working even better.
I don’t want to make a false start so I won’t post the final Unity package till it’s not on their website but I’ll share a lightmapping example with you that with probably be in the system documentation.
The scene before lightmapping
Using the tool you can prepare lightmap texture atlases in Unity, simply by dragging the objects to the chosen lightmap.
Once you’ve chosen your objects press “Export Scene” button
The scene gets exported to 3dsmax (also with Unity lights), where waits for you the External Lightmapping Tool helper.
After you adjust the scene lightning in 3dsmax, this little tool will render and save the lightmap textures to your Unity project directory and apply the lightmaps automatically.
In 3dsmax you can use regular “CTRL+S” shortcut to save your materials and lightning for future changes
After the rendering is complete you can come back to Unity and see the results.
Whenever you’ll have to rebake your scene (objects or lights in scene moved), just press the “Export scene” button again.
The tool will reload the scene in 3dsmax at the point you’ve leaved it at last save.

It’s some time since my post about Fedora & Vista dual boot using the Dell Media Direct button and I’ve realized that I don’t use linux at all.
It’s not that I don’t like to – I would love to switch to another more customizable system, but I can’t. Windows binded me with too many applications, 3dsmax, visual studio, Unity- just to name a few and it’s enough to make me stay.
It’s not that hard to setup this dual boot, but one false step can lead you to broking the Master Boot Record and data loss. This guide should protect you from such mistakes, however I still do not take any responsibility for the damage that can possibly be done :P
1. Get needed tools.
- Dell Media Direct CD
- MBRWiz http://mbrwizard.com/index.php
- GParted http://gparted.sourceforge.net/download.php [you’ll probably don’t really need this tool since in most cases you can calculate the drive index from the data given by MBRWiz, however if you want to get really sure then download it and burn to a cd]
2. Get rid of the media direct partition (not really needed, but why to keep it? :) )
3. Partition your HDD in some wise way, like: partition1 – Windows XP , partition2 – Windows 7, partition 3 (extended) – data
4. Install Windows 7 to the desired partition
5. Run MBRWiz, hide the Windows 7 partition and make the Windows XP partition active, look here for examples how to do that: http://mbrwizard.com/examples.php
6. Install Windows XP to the desired (active) partition
7. Unhide Windows 7 partition
8. If you’ve downloaded GParted then run it and note the partition indexes of Windows 7 and XP (numbers shown after …\sda). If you didn’t download it and you’d like to use a trick then probably you’ll get it working by adding 1 to the indexes shown by MBRWiz – note them somewhere
9. Insert the Dell Media Direct CD, while being on Windows XP and using command line navigate to your CD drive and write: rmbr DELL X Y where X is the index to the system partition which you’d like to run when pressing the regular power button and Y is the index to the system partition which you’d like to run when pressing the Media Direct button
That’s all, enjoy your dual boot dell laptop.
There’s also a way to sync the application data between those two systems so you don’t have to install the applications twice, but I’ll either refer to my friend article when he’ll write it or write it myself someday.

I’ve changed a little bit the list for last week
- Automatic setting the lightmaps accordingly to their name as soon as they appear in Asset folder
- Basic batch render script for 3dsmax, which opens max and renders&saves all lightmaps (yet hardcoded)
- A solution for applying materials, and setting up lightning have been overdiscussed
- An option for changing shader to lightmap-enabled one was implemented in the object list
- Handling objects that are not ready for baking (non-valid uv2 map)
- Lot of bugs have been repaired and code was send to the mentor for a review
(The Unity light is turned off :P)
Some first results – scene was setup in Unity and exported using my tools to 3dsmax where it was baked
- Implement an option for exporting default Unity lights
- Research, for an optimal, most universal and non-roadblocking solution for loading preset lightning and other settings to an external app which will be doing the rendering (thinking about further development)
- Implementing some of the advanced options
- Developing batch render script for 3dsmax
- Development of some small tools for helping users which uv2 seems not to be perfect correct (scale or offset)
- Code optimization, bug removal and probable reorganisation (depanding on Lucas review)

THIS WEEK SUMMARY:
- The main core with GUI has been done which contain a following options:
- A dynamic list of lightmaps (shown as buttons)
- Simply hierarchy display list for currently highlighted lightmap
- Most necessary options “Pick selected objects”, “Clear list”, “Export FBX”
- Optimal UV Packing:
- the size of lightmap spot for an object depands on its surface area
- the algorithm additionally “removes empty spaces” from each UV map in packing procedure
- The algorithm repeats itself with smaller sizes if packing the objects on the given lightmap area failed
- ASCII FBX Exporter (working mesh, material and uv export – with a small smoothing issue)
- Tested the exported fbx files in 3dsmax and Modo
FOR THE NEXT WEEK:
- Automatic setting the lightmaps accordingly to their name as soon as they appear in Asset folder
- Batch render script for 3dsmax
- Exporting with scene preconfiguration for 3dsmax
- An efficient solution for applying materials in 3dsmax
- Some tools for intelligent batch shader switch on the objects which will be lightmapped, but currently don’t have a lightmap-enabled shader
- Finding and eliminating current bugs

After some consideration I decided to change the name for a moment to make it less confusing for other people, because the project indeed is focused on the connection between Unity and Vray over 3dsmax, but the main core will allow everybody to use it for their own purpose with any software with a FBX importer and rendering system supporting UV’s on channel 3.
After a few days of work I’ve written the main core of the FBX Exporter which now allows to export any mesh objects, with their textures and for the moment – a UV on channel 1.
At first I was a little feeling a little uncomfortable when I’ve discovered that Unity splits vertices’s, however for my current project it wasn’t such a big deal. Accordingly to the assumptions the scene should be ready for baking on the export time, so I don’t have to really think about all those additional vertices’s that will show up in 3dsmax until it looks properly.
Later I’ve been a bit impressed in how sophisticated way was the Unity API designed – it really makes writing for it easy and comfortable and that’s something I would not say about Autodesk FBX documentation, because there’s no documentation at all and the most of my time I spent on endless experiments, trying to figure how things work there inside. I still cannot say that I figure out everything cause I’m having a little smoothing problems and I didn’t test it with other objects that won’t be attached as one mesh.
At the moment I would like to give a few tips to anybody straggling with FBX in ASCII mode.
- At exporting UV’s from Unity to FBX be set the “MappingInformationType” to “ByVertice” and “ReferenceInformationType” to “Direct”
- Most of the properties supported by the object in an FBX file aren’t needed when you want just import it to 3dsmax, just be sure to left 6-7 last properties
- When exporting a reference to a texture there’s no need to export Video objects connected with them.
- 3dsmax importer is tolerable when it comes to file paths, you may use “/” as well as “\”
I’ve also researched other areas like UV packing in Unity, running from command line and lightmapping in 3dsmax.
As it turn’s out, one can get a really fantastic results will well adjusted materials.
Below you can see a simple scene without any Unity light (not well unwrapped though) which shows the difference between lightmaps rendered with objects that contained bumpmaps in their materials and those which don’t.
On the bumpmaped I’ve added a little reflection to the floor and as you can see it became rendered pretty well too.

Basically the system is automating the bake process for Unity powered games using a powerful rendering software VRay.
The Unity team proposed a bit different workflow and not all the original ideas will be implemented as the part of the system. It was rather clear that it would happen since the ideas I described were indeed invented rather quick for a game which I’m working on with my team (no further details now :P )
Nevertheless I’m very happy with the changes proposed by Unity team and those which came after the talk with my mentor Lucas Meijer. I think that it’ll all make the lightmapping process in Unity really simple and effective.
I didn’t setup my goals yet, since I want to be rather sure what exactly can be done in those 6 development weeks, but since many of you may be interested in the details I will often blog here information about the development progress and plans – starting from today. Feel free to submit here your ideas in a form of comment :)
Here’s the scratch of the workflow made by Joachim Ante:
From the end-users artwork we simply require:
* At import time per object unique uv’s are required (normalized to a range of 0 … 1)
[As a first step, we can just require the user to provide it, or we could automatically generate them later on]
The lightmapping process works in 4 steps:
- Go through the scene and pack rectangle UV coordinates into a texture sheet. They can be stored in the renderer using lightmap tiling and offset: http://unity3d.com/support/documentation/ScriptReference/Renderer-lightmapTilingOffset.html
- Create an FBX file from Unity scene. Export both the primary and secondary uv set with the packed UV coordinates. This means that we “offset-scale pack” the per object uv’s we have, into a new “baked uv sheet”. (FBX supports Ascii mode, so it’s quite easy to export)
- Launch Max from inside Unity through the commandline batchmode interface, automatically open the exported FBX file and start the lightmapping process
- Once the batchmode completes, Unity imports the textures and applies them to the renderers using the Lightmap Settings class and renderer.lightmapIndex.
Here’s a short summary from the discussion with Lucas:
- Our main goal is to “unchain” the baking process, so that one can modify the scene in Unity as much as he wants – and in every moment start the bake process (possibly several times during the work over the scene) before, the user were pretty much blocked to do changes in the imported model inside Unity
- We’ll test the system with max and vray, but it should work with any fbx reading, lightmap creating program with some additional work
- The user would have a choice (by selecting objects from list) which objects are meant to take part in the bake process. On the selection list will be placed combo boxes beside each object, to make user choose a lightmap-enabled shader.
- The scene is being exported into ascii-fbx file and then imported into 3dsmax. During the exporting process we set the 3rd channel uv using the existing (second?) channel uv which will be scalled and offseted. (We will demand an unwrap uv on second channel from the user for the beginning – later on it may be created automatically for him) [credits: Joachim Ante]
- All the UV’s will be packed to a single or a few big texture sheets – a benefit in performance
- We’ve got an idea to make vray materials assigning automatically according to the material name from unity – that would help the designer in preparing the scene to the baking process (when one doesn’t use any keywords in the material name in Unity then the default vrayMtl with a diffuse map (eventually in bump map – if it makes sense) will be assigned.
- The light setup in 3dsmax is not yet outvoted – although we’ve got two conceptions:
- The vray-lights are being created dynamically on the image of the lights created in Unity
- We leave the light setup to the 3d artist so he can import a light rig to the scene and then bake
- After the baking process is done the materials in Unity stay unchanged, but using the LightmapSettings class the appropriate parts of the lightmap texture are assigned to them (there are a few issues waiting to be resolved)
We’ve also considered some nice icings as for example forwarding 3dsmax communicates and render progress to Unity or a possibility to choose a custom renderer – Mental Ray for instance.
Here is a simple diagram of how the things will work inside

I was trying to get a matrix for a projection of any point to a line given by the following equotations:
After some time of research I’ve ended with the following result:
Of course the result isn’t new at all, it was just a big efford for me to do that at midnight – so I guess it may be worth saving it here.

This post is meant to be a short introduction to a new science branch on my blog dedicated programming in Assembler.
One can think that the use of Assembler is deprecated these days, but there are still many reasons for a computer scientist to know this low-level language.
The primary reason to program in assembly language, as opposed to an available high-level language, is that the speed or size of a program is critically important.
For example, consider a computer that controls a piece of machinery, such as a car’s brakes. A computer that is incorporated in another device, such as a car, is called an embedded computer. This type of computer needs to respond rapidly and predictably to events in the outside world. Because a compiler introduces uncertainty about the time cost of operations, programmers may find it difficult to ensure that a high-level language program responds within a definite time interval—say, 1 millisecond after a sensor detects that a tire is skidding. An assembly language programmer, on the other hand, has tight control over which instructions execute. In addition, in embedded applications, reducing a program’s size, so that it fits in fewer memory chips, reduces the cost of the embedded computer.
Here is a picture illustrating the converting process for both high and low level languages.

It’s a trick that makes posible to write polish characters on your mobile in Python editor using Nokia SU-8W. All that’s needed is PyS60 installed with appuifw2 module.
To write a polish letter press Alt Gr + Key, where Key is the usual key under which polish character is hiden.
Few things that I could not ommit – the letter “ź” is under key “q” instead of “x” and the capital letter “Ć” is under “W” instead of “C”
Use with the default “UK, US English” layout.
And here’s the pys60 code of the editor:

Well this is not the best solution I’ve invented, but it’s all I could do. I’ve been searching all over internet for hours, trying things to make those characters work everywhere on the phone, but with no success.

Matrixes seem to have a lot of wonderful properties, for example they may help checking if given triangles represented each by three complex numbers (verticles) are simillar.
So, two triangles represented by complex numbers and are similar if, and only if:
Proof coming soon.

True :) However I would put physicists a bit nearer mathematicans ;)

God damn. I took me about a half of an hour to Google that out…
Things to do to fix Visual Studio C++ Express (Probably in most cases you don’t have to delete those entries first. (worked for me)):
- Go to Start -> All Programs -> Accessories -> Run, and type “RegEdit.exe”
- Locate the following folder/key: “HKEY_LOCAL_MACHINE\SOFTWARE\Classes\VsWizard.VsWizardEngine.9.0″
- Right click -> Permissions -> Advanced -> Owner (Should be getting alot of “No permission to do that” likely-errors)
- Click one time on “Administrators”, then click “OK”.
- Expand “VsWizard.VsWizardEngine.9.0″, Right Click CLSID and do the same. (Do that to all subfolders which is under “VsWizard.VsWizardEngine.9.0″ aswell, if any.)
- Right Click “VsWizard.VsWizardEngine.9.0″ and click “Delete”, choose yes if you get an confirmation window.
- Right Click “VsWizard.WizCombo.9.0″ and set permissions for that folder and subfolders, and delete that one too.
- If everything went fine, you shouldn’t have any folder called “VsWizard.WizCombo.9.0″ or “VsWizard.VsWizardEngine.9.0″ anymore.
- Goto: Start-> All Programs -> Accessories, Right Click “Command Promt” and click “Run as administrator”.
- Navigate to your Microsoft Visual Studio IDE folder, by using the “cd” command. (usually “cd C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE”)
- Type “RegSvr32.exe VsWizard.dll”. You should get a window telling that you’ve registered that dll file (or something like that).
- Start RegEdit.exe again (if you haven’t), and locate to “HKEY_LOCAL_MACHINE\SOFTWARE\Classes\VsWizard.VsWizardEngine.9.0″. This should have been added again.
- Right Click -> Permissions, you should see “Administrators” and “SYSTEM” or something, click them both and enable Full Control and Read.
- Do the same for subfolders (should’ve been done automatically), and then do it for “VsWizard.WizCombo.9.0″ and subfolders, which should’ve been added again.
- Close RegEdit.exe
- Start the version of visual studio you have, create a new project, and watch how it works!
uff… I hate Microsoft software…
