Luca Tringali Hi Luca, have you worked on addressing the points raised in the comments you were made? Also I am wondering if kdeedu is really the place for this app, I understand it's a very useful application for science/laboratory situations, but is that really something a student would use? Cheers, Albert Hi, Just a point of view. It is somewhat fit kdeedu ideally. At least in the same order of magnitude as Rocs or Cantor. There are many other professional tools for curves fitting (Scilab, Octave for various data fitting algorithms, RKWard and PSPP for regressions). Kartesio is very good to acknowledge students with the basics of some modern data fitting algorithms. If you think is does not, can the module for kde-science be created for such applications (Kartesio, Rocs, KST, Cantor, Cirkuit, KStars (its latest improvements are largely for professional and astronomy hobbyists, not for students ;) ) maybe RKWard if its developers ever decide to join)? Just my 2 cents. Best regards, Yuri

Hi Albert, I'm working on the points but, since I'm kinda busy with my work, the code I have written for now is still not stable. I think it'll be ready in the first week of January 2014. If you study something, at high school or university, which includes experiments (chemistry, phisycs, biology, engineering, etc...) you need a best fit calculator. So, philosophically, it is something very similar to Kalzium Calculator.

Ooops: I thought I already corrected this problem, for some reason I did not upload to git this correction. On my system the build goes fine also with that line, but I decide to remove it because it can cause problems with other compiler configurations (on mine I just get a wrining, on other systems it is an error). I corrected the line, anyway just commenting it should be fine: this line is not needed, and it presence does not affect the running of the program. I read that you have commented this line, so you should now be able to run Kartesio. To try it, you can load the file "parabola.kartesio" which is on the git repo.

R: Re: kde review kartesio
Yes, I also think adding new features now is not a good idea in this moment.
This is the reason why the new version of Kartesio I uploaded to git (about 45
minutes ago) contains basically all the corrctions you suggested, but no new
features.

Hi, no, build.sh is not needed. Since I'm kinda lazy, I prepared a shell script to run the following commands: mkdir build cd build sudo make uninstall make clean rm CMakeCache.txt cmake .. -DCMAKE_INSTALL_PREFIX=`kde4-config --prefix` make sudo make install so I don't have to type all those every time I want to build Kartesio again. I'm not sure why you get that error, mainlybecause I don't know which is the instruction that gives that problem since I changed a lot the code in these hours. Try to download the latest git version and build it, so I will know exactly where the problem is.

You asked for an inclusion in KDE and we are reviewing Kartesio. There is
already a big amount of work to be done from the comments you got. I don't
think adding features now is a smart move, review is a phase where your program
should reach KDE standards. Using Qt libs wherever possible is the priority and
getting all the required fixes will make you busy enough.

Hello everybody, just wanted to tell you that I made some fixes to the code, based on your suggestions: *comments in header files *deleted some unseful string *check routine to avoid that a dangerous string like "**" or similar is used for the function *add where to download zorbaneural in cmake module *in neural network algortihm, check if all the points are between 0 and 1 *check if the maxima report is empty before showing it *added file messages.sh I also cleaned it up a little, to make it more readable.

Yes, those files are there just because I found them useful, but I can remove

I know, I wrote where to find it in Kartesio project overview but, since
almost everybody had some troubles with it, I will make this thing more clear.

Yes, the correct way to express a power is ^. So you should write x^2. There
should be a check routine to avoid that a dangerous string like "**" is used,
and I'm surely integrating this check in the next release.

Actually there is not: I'm working on a new window for the next releases:
basically, there will be a button over the table, something like "Edit datas".
This will open a new window in which it will be possible to import/export CSV,
sort X axis values, add other rows or deleting some...

No, at least not only. Originally, line 117 and 118 were collapsed into one
single if instruction, it slip it in two because it was too long. This line
checks if the current char (which is a C++ char an not a QChar) is permitted or
not. Permitted characters ar letters, numbers, and some other simbols (for
example "+", "(", etc..).
Could this instruction be shorter and more elagant? Probably. But it works,
and actually I think it could stay as it is.

I know it, I'll try to make the code more readable, but I do not have so much
time so usually I prefer to dedicate my time to new features or corrections
instead of making them prettier.

I'm already working with QTempFile for the next release of Kartesio.

Yes, this is an heritage from the older version of Kartesio, that was based
mainly on plain ANSI C++. Those mixing are just an hack to make Kartesio work
immediately. If I'll have time, I will "translate" everything into Qt, but
first of all I would like to apply other features.

R: Re: kde review kartesio
Hi, actually I have not prepared any binary package. Anyway, you can install Kartesio downloading the source code from the git repo (https://projects.kde. org/projects/kdereview/kartesio), installing the library libzorbaneural (https: //www.gitorious.org/zorbaneural/zorbaneural/trees/master/binary- packages/libzorbaneural-0.1), and running the build.sh script you find in the Kartesio root folder. Also, you should have installed the program "maxima" (just the program, dev libraries are not needed) to have Kartesio fully working. If there are some troubles in building Kartesio, just ask me.

R: Re: kde review kartesio
Hello, libzorbaneural can be found here: https://www.gitorious.org/zorbaneural/zorbaneural/trees/master Here are also some packages for the stable version (deb and rpm): https://www.gitorious.org/zorbaneural/zorbaneural/trees/master/binary- packages/libzorbaneural-0.1 Once you have installed it, the build should go fine. The screenshot folder and the .pro file are not needed, if they are a problem I can remove them. Talking about the system call in calculations, this is the reason why actuallt Kartesio works only on GNU/Linux systems. Why I did it? Because it was the easier way to do that. In the next release of Kartesio, this problem will be solved. I'm not very practical with translatable strings, so I excuse for the Message. sh: is there a wiki page to understand how to write a Message.sh file? I'm writing comments on variables in header files, in the next hours I'll publish them into git.

Re: Re: kde review kartesio
Yes, Kartesio is used to calculate fitting curves for experimental points: I, as a chemistry student, already used it for some laboratory reports. Actually, there is no other program like this in KDE: obiously you could obtain something similar with RKward, but this one is too much complex for fitting curves, and students usually do not like R. Kartesio does one thing, and does it simply and good. Caculating best fit curves with R is smilar to cross a stream with the Queen Mary.The most interesting feature of Kartesio is that it allows you to write manually the equation you want to use to fit the points (with other programs like LibreOffice Calc it's possible only to use 3 or 4 already implemented and generic functions). For example, I can choose to fit my points with "y=a*sin(b*x)" or with "y=(9.342/x)+c".

Hi Luca,

I figured that after it had crashed ;)

In my opinion you should not release your application with such an
obvious crash bug. It's not only this expression, the program crashes
whenever there is anything wrong in that text field. That's not
something you can defer to the next release.

I don't know if it makes sense, but you should have a look at the
calligra sheets part (aka talk to someone who knows about it).
Eventually that can be very useful for this purpose (unfortunately I
don't know exactly how they work).

You could replace a 2000+ character boolean logic expression which
lists all the letters in the alphabet by this:
c.isLetter() || QString("+-*/^").contains(c)
at least assuming you do the other thing I said and use QString
instead of char*.
This is a cleanup which is worth doing.

Writing correctly formatted code is mostly a matter of setting up your
editor correctly. Spend five minutes doing that ;)

Re: kde review kartesio
Hey!
A good thing, I think such a tool could be useful to me too (and I
know a lot of other people to whom it might be useful). Here's what I
noticed from a quick look (some has been said already I think):
* You probably shouldn't track the kdev4 file in the repository, same
goes for screenshots
* zorbaneural is a very fancy dependency, it's not even in arch's AUR.
You should put the git URL into the cmake message.
* I put x**2 into the fit box and clicked Fit, and it crashed:
http://paste.kde.org/741026/
* Did you think about laying out the UI around a splitter? On my
screen, the table takes most of the area and the plot is quite small,
and I can't change that...
* It would be useful to be able to import data in some way, e.g. from
a CSV file. I don't see a way to get data into the program except
typing every number into the cells -- or is there another way? If
there is, could it be made more obvious eventually?
* What does the code in calculations.cpp:117 do? It looks quite
curious. Isn't there a more elegant solution (it looks a bit like a
QChar::isLetter() implementation)?
* calculations.cpp:505 and 584 the same code like in 117 again? It's
weird enough to have that stuff once, but copied multiple times is bad
imho ;)
* Your code uses mixed tab- and space indent (sometimes it uses tabs,
sometimes spaces for no apparent reason). Most KDE apps use only
spaces, you might consider if you want to do that too. Sometimes, the
indent is even missing completely; you should indent one level after
each opening curly parenthesis.
* Same goes for the whole formatting of the code, it's pretty
inconsistent. For example, look at the spaces around operators or so.
* Instead of writing to /tmp/kartesiotmp.txt you should probably use
QTempFile. That will also take care of the deleting the temp file when
it gets deallocated so you don't need to exec (scary and
platform-dependent) rm commands.
* calculations.cpp:277 this makes no sense, there's a statement behind
a "return"
In general, you're mixing a lot of plain C / stdlib stuff into Qt
code. Is there a reason for that? For example, in calculations.cpp:148
you take text from a text field, convert it to a byte array, convert
it to a char* and then pass it to a function. Why not just pass the
QString? You can iterate over a QString like
foreach ( const QChar& c, myqstring ) { ... }
or also
for ( int i = 0; i < myqstring.size(); i++ ) { ... }
if you like that better, and you can also index it like a char*, as in
mystring[i+1] or so.
Also, nothing in your code is const and everything is public, although
almost everything could be const and private, but I won't get started
on that now ;)
This is not meant as a list of what you must fix, it's just my two cents.
Cheers!

Re: kde review kartesio
Hi, A few primary remarks: - libzorbaneural is needed but my distro does not have anything with "neural" in it (OpenSuse 12.3) what repo do I need to add in order to get it? The libzorbaneural website should be added to the cmake file so people can find this and packagers can add it to their distros. - I see a screenshot folder and some .pro files that probably are not needed - some doxygen comments for the variables in the .h files would be appreciated, if anyone else wants to fix bugs it'll help a lot. - Kartesio does not build for me, I get "/home/kde-devel/kartesio/src/calculations.cpp:278:1: error: control reaches end of non-void function [-Werror=return-type] cc1plus: some warnings being treated as errors" - I don't see a Messages.sh file to extract translatable strings. - I am not comfortable with the rm call line 181 in calculations.cpp => you can probably use more Qt classes here and in other parts of this file too.
