Happy Holidays to all!!!

The ConfigureChecksIntl.cmake is needed for cmake build. I checked
Johndhel's submission which is the tarball file then I found
the ConfigureChecksIntl.cmake file. I think the ConfigureChecksIntl.cmake is
not autogenerated file because that file existed in the tuxmath
cmake-modules directory. I checked again the latest revision both in
automake and cmake and its working fine.

Hi,

I got a different error when trying to pull from git:

dbruce@debian-laptop:/usr/local/src/git/t4kcommon$ git pull
Password:
Updating 03000a0..860950b
error: Untracked working tree file
'cmake-modules/ConfigureChecksIntl.cmake' would be overwritten by
merge.  Aborting

By deleting that file locally, I was then able to pull.  So is this a
generated file?  If so, we shouldn't be tracking it in git.

Anyway, after that, the build and install itself didn't have any problems.

It should be fixed now, as of commit *
860950bd6a4ae13262302d3144be912b188238d5*.

I'm having exactly the same problem, albeit with a different error. I
believe Johndhel forgot to make changes in the CMake build system. (in
commit *03000a05083d3b95e548bde6db2a61ec2cae594f*) Building using autoconf +
automake seems to work fine.

Hi Victor,

I tried to fresh clone the t4kcommon and build the master branch and its
working here.

You can use the previous revision while we investigate the possible cause of
your problem.

Hi,

The linebreak code in t4kcommon is breaking my build :(

$ cd t4kcommon
$ mkdir build
$ cd build
$ autoreconf -if ..
$ ../configure
$ make

-- error
http://pastebin.com/3XBSJDLM

I checkout to Aviral's patch, in Dec 15 and its running fine (without
linebreaker)

I tried again (after checkout master), and I had 'SIZE_MAX' undeclared in
xsize.h.
http://pastebin.com/1az1KhJR

When i looked into it, SIZE_MAX came from limits.h, and should work well.

I didn't understand at all :)

Its working fine in yours pcs ?

Sorry, sent the message before I finished what I was trying to say.
The run-time debugging output involves a couple of macros defined in
t4k_common, plus a group of bit flags (can be combined with '|') that
determine what part of tuxmath should produce output.  Just look at
mathcards.c for examples of how to use DEBUGMSG and DEBUGCODE.

The needed includes are #include "globals.h" and #include <t4k_common.h>.

Actually, I prefer corresponding braces to be vertically aligned in
the same column, but I'm not a zealot about it.  What do other tuxmath
devs think?  If most people like the opening brace at the end of the
function signature, I'm OK with it, but let's keep the changes to a
minimum unless there is really a consensus.  However, I think we all
agree that my two-space indenting can be changed to four spaces.

Anyway, it looks like you've put a lot of work into it so far.  It
looks like you are keeping the same basic idea of a doubly-linked list
to hold the questions.

Hi Aviral,

Something like this should really go to the tuxmath dev list, which I cc'd

It will be quite a project, and probably involve some "re-inventing
the wheel" if you come up with another implementation that does the
same thing.  Make sure you understand everything the current system
does, because we added several things piecemeal because a previous,
simpler version didn't quite do something we needed it to do.  I
really don't want to drop any of the functionality of the current
mathcards.  Mathcards even stores a linked list of questions that were
not answered correctly, for use in a subsequent review game.  We never
have implemented an option to play such a review game, but it is
something I eventually want to get done.

I'm really hesitant to rip out a large section of working code.  The
only bug I was aware of was the generation of "ooo" questions with
indeterminate answers, which ought to now be fixed.  I don't think a
complete re-write is needed to add the ability to support more than
one simultaneous game (for the LAN server, in case anyone is
wondering).  If you see ways to clean up the "messy" parts, feel free
to make suggestions, but I don't see the case for a complete re-write,
especially if it spills over into significant changes for game.c,
server.c, and the options system.

Of course, tuxmath is free software, and you are perfectly free to
write whatever you want.  Just keep it in its own branch until it is
complete and thoroughly tested.  If it does everything the current
mathcards does and is more clean and readable, we would be happy to
use it.

Best,

David

There is a new powerup that simultaneously zaps all asteroids on the
screen with a given factor.  It is one of three powerups that are
randomly earned each level, and activated by pressing [shift].  But
what I think you are seeing is a drawing glitch that appears with each
regular, "single" zap.  It looks to me like a laser shot with a
slightly different angle gets drawn during some of the frames when the
laser is fading.  Aviral had to re-work the laser drawing code to
enable the multizap powerup.

The gameplay itself is still correct, right?

Best,

David

Hi,

Good day.

I'm not sure if I am missing something, but every time I am zapping an
asteroid, a multiple zaps or lasers will appear and its like a crazy laser,
and it overlaps above of the tuxship. Is this the new smart bomb power ups?

Thanks.

Guess I'll add a me too voice. No reason it can't wait, though.

I was just thinking about something like that.  For whatever reason,
when I started working on tuxmath I decided on using only 2 spaces per
indent level to conserve space, as I tended to use more deeply-nested
conditionals.  Now, I think 4 spaces would be more "normal", and I

I thought it looked pretty good.  So I'd be fine with that at some

That's sound great for me. But I think we can implement that after the GCI
contest.

The "Fractions" version of Factoroids is definitely broken at the
moment.  We should consider how to either restore the previous
behavior, or have it be tied to specific primes like the factor game.
Sounds like an upcoming GCI task....

David

Yeah, we must definitely check on that, as it was written specifically for
Factoroids, without any testing on the fractions thing.

Aviral

Hi David,

I think I remembered someone from GCI contributors posted here a bug related
to that issue. And also I noticed when I played the fraction section in
factoroids the number 2 is only available and some fractions need some other
number to simplify. I think the new prime gun implementation affected the
fraction game.

Hi Aviral,

I worked on factoroids a bit to try to prevent rocks with invalid
numbers.  I wrote a validate_numbers() function which basically
factors out all the valid primes, leaving 1 if the number is valid for
that wave, or a larger prime (say, 83) if the number is invalid.

It turns out that generate_numbers() *always* creates valid results
(or at it least did in a test run of 10,000,000 iterations).  So I
feel confident that your function is fine.  Somehow, these invalid
asteroids are getting created when the larger numbers get broken down
during gameplay, probably due to some sort of float-integer conversion
issue.  I'm not quite sure of the exact issue, but now
FF_add_asteroid() just returns and prints an error message if it is
passed an invalid number, so they don't show up in the game.

Anyway, the "new" factoroids is shaping up to be a really cool
educational game, thanks to great work from you and the rest of the
Google Code-In contributors.

Best,

David Bruce

Hello,

I really hate taking this way because this is a development list but I just
wanted to make you aware of the point that it has been 24 hours since I've
completed the translations and my task has still not got accepted -
http://www.google-melange.com/gci/task/show/google/gci2010/tux4kids/t129089701854

I think you're aware of the fact that a student can only work on one task at
a time, so you must be fast at accepting the claims, closing the tasks etc.

Thank you! And sorry for posting it here - there were no other means of
communication mentioned on melange. :-)

By the way, the email id mentioned on melange is wrong, so you may please
correct it -

Yes, we figured this out a few days ago with Haiku, only admins can
reassign the tasks.  So we added another admin so now we have three.
Also only the admin(s) can approve new tasks or add new tasks.
Mentors can suggest new tasks but they won't be public until an admin
approves them.  Hope this helps.

   Hey guys,

   I am a grade 2 teacher and I have been using TUXMATH. In my classes I do
   not teach rote-learning. Instead I teach strategies and TUXMATH is a great
   way for them to apply the strategies in addition and subtraction that I
   teach.

   I have my students use the training section where they start simply by
   typing in numbers then go things like addition 1-3 and so on. I like how
   it keeps track of which levels students have completed. This is a great
   chance for me to see how the students are doing....

   The only problem is that some of the levels are really really long. For
   example, sums to 15 has the students doing over 200. Many students can not
   do enough of these during the time they have. I would say 75 is a good
   number.

   I get the idea that the levels should get harder, but I am not sure if
   making the levels longer achieves this.

   Is there a way for me to decrease the number the students need to
   complete?

   Thank  you
