Hi all,

it has been a while since my last post and even longer since my real activity here (7 years ago!! :) ). The time runs really fast - unbelievable.

Well during the last 7 years I finished university studies in the Czech Republic, moved to Denmark where I successfully finished PhD. studies. Then I got married bought a house and got a job at the Danish Technological Institute :) . But I still keep DonationCoder part of my life - every morning at work I drink a cup of tea from the mug I got during NANY 2009!  :-* .

Yeah. I will have to ask the jazz-plugin developer to make sure that this does not happen ;)

EDIT: here is the question

Have you tried to restart pc? Also please check out that does work for you. Let me know if it does not help.

EDIT: btw. I prefer to use Google Chrome as it has the fastest WebGL.

Thanks :) I am glad to hear that :Thmbsup:

Relationship btwn. Reviewer and Product REVIEWER: I am the author of the game.


I have put together a small online open-source piano game. You connect an electric piano to your computer, install Jazz plugin to make Google Chrome communicate with the piano and then you start playing. I use it almost on every-day basis and I must say that I am very happy about it. It really helps me to play songs that I like in an easy manner!

I have prepared three small videos about the game. The first video shows the game in action. The second video gives a brief overview of the game. The third video shows how to change default parameters of the game.

PS: Don’t laugh :D. I know that the videos are VERY amateurish ;).



How to change game parameters.

Here is a sample link which loads songs from my dropbox public folder.

Who is this app designed for:

Musicope is for anybody who would like to play a piano in an easy manner.

The Good

Musicope helps in playing a piano quickly and without the need to learn notes. It is an online game and it is open source! This means that you can very easily integrate it into your blog or modify it to your needs.

The needs improvement section

The game is in its alpha phase. I have used it only together with my piano Yamaha PSR423. The game surely has many bugs and lacks plenty of features :). As for now, I am the only developer. More developers and testers are welcome to make the game better!

Why I think you should use this product

This game helps you to play the piano in a very easy manner. No need to learn notes. The game is free and open-source!

How does it compare to similar apps

There is Synthesia which is an offline paid alternative. There is also PianoCrumbs which is online and very limited with a lot of adds. This game is open source and free. It lack features that Synthesia has, but since it is open source, nothing restricts you to implement the features that you like!


I hope you like the game :) . If you have any comments, if you find any bugs (and there are many), or if you would like to contribute in any way, do not hesitate to contact me.

Personally I like photo captchas (pick all girls among men etc :P ) such as:


And I guess they might be very difficult to brake as well

Living Room / Time management software
« on: April 27, 2010, 01:17 AM »

I am looking for an application similar to Microsoft Project. The only thing that I need is an application which would allow me to hit a global hotkey to add a new task. I would either choose a task which has already been used before or I will write down name of the new task and hit enter. That is all. Whenever I create a new task, the program would know that the previous task has been finished, so it would automatically know when the task started and stopped. Then there could be stuff like graph plots, export etc. The more keyboard hotkeys the application supports the better :)

PS: A FARR plugin would be nice but doing all the exports and graphs would be too complicated I guess.

PPS: I want to use a time management software so at the end of each month I know what I have been doing all the time. Another note is that I would like to describe what I am doing ca. every hour rather than every day and therefore adding a new task has to be as simple and fast as possible.

F# because it is a functional language, and it runs on Net (a lot of libraries available)

I switched from Ditto to CHS because Ditto was taking 50% of my CPU. But when I copy paste ěščřžýáíé I get ìšèøžýáíé. Is there any way how to solve such a problem? I use English Win7 with Czech Local settings.

Well I would start by erasing everything in user variables settings. This is where google translate stores last languages. I can not image what else would cause it.

Let me know if it helps.

Post New Requests Here / Re: IDEA: a better DimScreen
« on: November 25, 2009, 06:11 AM »
I have implemented it by myself. You can download it here:

Run "Din.exe param" to increase brightness by "param"
example "Din.exe 10" or "Din.exe -15"

Run lcd.exe (lcd.ahk)
Hold win+scroll to increase decrease brightness
hit win+1 to go to stand by

Here is the sourceCode of the Din.exe

It looks to me that DimScreen written by Skrommel does not lower down the screen Brightness, but does some other magic instead.

So I suggest:
In Windows 7, you can go to "Adjust screen brightness" and modify the screen brightness without a need of fn keys.

There exists a Backlight Control Interface:

There exists VB.NET example:

Would it be possible to implement it into AHK? If not then I will try to do my best to code it using C#, F# or anything else, so there would be an option to adjust a real LCD brightness :Thmbsup: But I must warn you that I have a zero experience with Windows API!

Best regards,

PS: One additional idea: zero brightness = turned off LCD screen

I always open new tabs for all individual "unread posts" pages - then I open tabs for the topics that interest me. When I'm plowing through that, I repeat the process to catch new topics that might have popped up while I went through the first cycle :)

I agree. This is far the best solution. Thanks :Thmbsup:

I have one question. When reading unread posts I usually go through them and middle click those I like to display in a new tab. When I pick all the topics I want, I read them. If the unread posts are on multiple pages I go to the next page. And here the problem occurs. Let say I have middle clicked on 5 topics. When clicking on the next page, the five topics are not unread anymore and the whole list moves up. So the result is that I have to click on page 1 once again to see the 5 topics which have moved from page 2 to page 1.

So my question. How do you solve such a problem :P ? What is your way of reading unread posts? Probably, I use a completely wrong way to read them :-[

Thanks in advance,

Developer's Corner / Re: What's your Programming Language?
« on: November 15, 2009, 02:43 AM »
Is it that important if the program takes more or less memory? Or if it is a few percent faster or slower? Of course there are fields where this matters (scientific research and even there, they use Matlab, Python, OCaml etc. even though they are slower -> why?) but for a daily code, I do not think it really matters.

My primary decision point is how easy is to code and how I enjoy it (first order functions, pattern matching...). How the language helps you to parallelize the code, how to protect your code against bugs (units of measure, strong typing, immutability...), how to easily extend the language, how to debug (immediate scripting) it etc. And I really do not enjoy to code in C++. Java is better / simpler and and any modern functional language like F# or Scala goes even further.

PS: I do not say that C++ does not have its place but I do not understand why everybody uses it just to gain a little in memory and speed. I wonder why you do not code in assembler to gain even more speed :)

I use F#. I think, that any functional language is worth learning :Thmbsup:

That is a pity. Office 2007 unfortunately does not have MSE7 debugger (just-in-time debugger for f.e. javascript) anymore. The very last version having it was Office 03 and Frontpage 03 and of course any full Visual Studio.

Another stupid thing is that MS IE does not give a line number as a part of try catch error information. Both Firefox and Opera do.

I am afraid that without knowing an exact place of the bug, I can not do anything about it. :(

FARR Plugins and Aliases / Re: CZB pack
« on: October 04, 2009, 05:39 AM »
No, it has nothing to do with Java. Do you have Microsoft Visual Studio (2008) installed? Or do you at least have Microsoft Office 2003 installed? :)

FARR Plugins and Aliases / Re: CZB pack
« on: October 03, 2009, 12:58 PM »

one probably last question before I start searching for the bug. Does the timer plugin in the CZB pack give you the same error and do you actually see the menu offering you languages? This will help me to either search for the bug in google translate or the menu addon.

You must understand that I do not know where to start as there are many many objects which could possibly produce the error. If you were deeply interested in helping out, then there are options how to find out directly. But it involves activating debuging - registry changes and microsoft JIT debugger installation, so I do not want to bother you with all of that...

Thanks. It is however difficult to track the bug as it does not happen to me. So could you please give me more information?

Does it happen only when you type "gt en"? or any other language? Please be precise even with spaces etc, so I know when exactly this happen.

Do you use fsubscript downloaded from this thread or any other?

Does the plugin work even with the message, i.e. can you use the google translater in CZB?

Is there anything else which might help me? :-[

Thanks for the information

« on: October 03, 2009, 06:43 AM »
if you find any other bugs, or have any ideas let me know. I have some time for CZB coding now

If you have some time, I get the same Google Translate error as Anaderi mentioned above: https://www.donation....msg174212#msg174212

Could you please translate what it says?

czb is back! :Thmbsup: What's your take on this:
Hi, the (very) old ninjawords plugin I've been using now stopped working. It seems has been taken down. The plugin in the CZB pack of course does not use that but instead loads a part of the regular NW page and works fine. But it requires a "return" to run. By now I'm really used to "alias phrase " (instead of "alias phrase" + enter) for word lookups. So what is currently the easiest way to mod the current CZB pack ninjawords script to run on regexmatch (without requiring a return)?

Sorry for the late answer. I have quickly add it. so you can update ;)

To the jscalc bug: it is a bug but I do not know how to solve it right now. The problem is that always when you type it evaluates at the background. And when you hit enter it evaluates again. So if will have to separate the two evaluations somehow. Lets see if I can do something about it ;)

EDIT: yeah. I would need to limit scope of an eval function but I do not know if it is possible. Any ideas?
