This page is a diary dedicated to the work I have been honored to do with LibreCAD this Google Summer of Code 2015 period.

== COMMUNITY BONDING PERIOD ==
= Community Bonding Week 1 =

* Celebrated my acceptance into Google Summer of Code 2015 with my friends at the Limbe Semme beach

* Getting to know other students in Buea selected for GSoC.

* Updated my repository on [https://github.com/Ngassa/LibreCAD github].

= Community Bonding Week 2 =

* Filled Student Foreign Certification Tax Form

* Discussed with my mentors the possibility of a wire transfer for work during the bonding period. No channels were open apart from Paypal. 

* Updated my repository on [https://github.com/Ngassa/LibreCAD github]

= Community Bonding Week 3 =

* Looked at the lc_splinepoints code in librecad/src/lib/engine/lc_splinepoints.*

* Worked feverishly and biased my efforts on my final year Management project ( meetings with supervisor, Writing Theoretical and Literature review, conceiving and administering questionnaires, etc ) which ate up the next fortnight. 

* The intention was to go furthest as possible with Final year School Project so that when GSoC coding begins, I can concentrate more on my LibreCAD project.

= Community Bonding Week 4 =

* Discovered a Paypal account at the end of the Community bonding period.

== CODING PERIOD ==
= Week One =
= Monday May 25th =

* Had a meeting with Women Techmakers Arm of GDG Buea organizing upcoming [https://plus.google.com/u/0/events/cdl24bk07spiac2o2fduaan9d24  Google  I/0 Extended 2015] at my University.

* Reading Documentation on [https://drive.google.com/file/d/0B-pwKjF4CzPzc3UzZlFnNEtiWDQ/view?usp=sharing Conics Sections in LibreCAD] given to me by my mentor Dongxu Li.

= Week Two =

= Thursday June 4th =

* Hurray! My Google Summer of Code finally package arrived my University today and I was called to come and collect it.  

= Friday June 5th =

* Had a meeting with the Mentor for Google Developer Groups in Cameroon. He cautioned me on the importance of communication and daily coding on my project.

* Almost done with my Final year Research Project.Was working on corrections given by my supervisor the whole day.

= Saturday June 6th =

* Updated my github repository today.

= Week 3 =

= Monday June 8th =

* Synced my github [https://github.com/Ngassa/LibreCAD repository] with LibreCAD's.

* Installed and ran LibreCAD from source.

* Studying RS_Ellipse::getTangentPoint() and LC_SplinePoints::getTangentPoint() to help create RS_Hyperbola::getTangentPoint().

= Tuesday June 9th =

* Hyperbolas are unbounded and disconnected too. Investigating how finding the tangential points of splines can help the case of hyperbolas.

* Read articles by www.qcad.org on [http://www.qcad.org/doc/qcad/3.1.0/reference/en/scripts/Draw/Spline/SplineControlPoints/doc/SplineControlPoints_en.html splines]. Each branch or arm of a hyperbola can be seen as an open quadratic spline.

= Wednesday June 10th =

* Discussed with my mentor in IRC today and he gave me [http://wiki.librecad.org/index.php/LibreCAD_users_Manual wiki link] for LibreCAD.

= Thursday June 11th =

* Re-established contact with my co-mentor Ries.

* Discussed with mentor dli_ on #librecad.

* Understood what class RS_VectorSolutions is. 

* Working on [https://paste.kde.org/pir5jd87w math algorithm] for finding tangential points from a given point outside a hyperbola.

= Friday June 12th =

* Awaiting mentors' response to my question on IRC channel on [https://paste.kde.org/pir5jd87w math algorithm].

* Using calculus to solve the above math problem. It's quite cumbersome and I'm having a hard time.

= Saturday June 13th =

* Continued work on cumbersome algebra and calculus on tangential points to the hyperbola. I'm excited that my thinking was the same as [http://math.stackexchange.com/questions/214977/general-equation-of-a-tangent-line-to-a-hyperbola?rq=1 this] except that my hyperbola is centered at (xo,yo) rather than (0,0).

* Succeeded to have a general formula to obtain the intersection point (h,k) of the tangent line and the hyperbola. That was quite tedious.

* My mentor asks for Proof of concept code on a daily basis.

* Next task is implementing the math algorithm which I developed.

= Week 4 =

= Monday June 15th =

* Discussed my math algorithm with my mentor dli on #librecad. 

* Started doing some [http://pastebin.com/TmWXQhEh minor changes] to my LibreCAD [http://pastebin.com/x3tBUBw6 repository] today.

= Tuesday June 16th =

* Today I had my final year project defense in school.Thus, I couldn't do any work on GSoC LibreCAD project today.

= Thursday June 18th =

* Studying lc_splinepoints code to finish writing the getTangentPoint of a hyperbola

= Friday June 19th =

* Developed a heuristic to solve the getTangentPoint() of a hyperbola.

* Emailed the [https://paste.kde.org/p9sw0q6lb paste] to my mentors for review.

= Saturday June 20th =

* Awaiting my mentors review of the heuristic before proceeding.

* Attended the Silicon Mountain Conference today.

= Week 5 =

= Sunday June 21st =

* Adjusting the getTangentialPoints() algorithm for a unit hyperbola based on my mentor's corrections.

= Monday June 22nd =

* Sent [https://paste.kde.org/px1krxfhc adjustments] to getTangentpoint() member function algorithm over to my mentor for review.

* Been having discussions with my mentor on code snippets like [https://paste.kde.org/pa1axlysg this]. Hustling towards a working prototype.

* Showed my mentor some [https://paste.kde.org/pzvmlq1yc code snippets] that compile today.

= Tuesday June 23rd =

* My mentor gave feedback and corrections to the code snippet I tunrned in yesterday.

* Have done some [https://paste.kde.org/pxz2wpd9o corrections] to the code snippet.

* My mentor proposed a much more concise and [http://www.texpaste.com/n/u6dkvzc0 maintainable algorithm] which I'm incorporating into the Hyperbola code.

* LibreCAD Build is [https://paste.kde.org/pnpgabtyj broken]. Downloading Qt5 to run LibreCAD with while Lead developers fix this issue.

= Wednesday June 24th =

* Upgraded to qmake-qt5, updated my LibreCAD repository and build it.

* Awaiting review from my mentor for the [https://paste.kde.org/pq37vefit improved] the code snippet.

= Thursday June 25th =

* Did not do any work today due to housekeeping. 

= Friday June 26th =

* More critique on code from my mentor.

* Chatted a little with brlcad on #brlcad and ries on #librecad today.

= Saturday June 27th =

* Today was a lazy day for me. Did not code.

= Mid-term Evaluation Week(Week 6 )=

=Monday June 29th=

* After a deeper look at my logic of getTangentPoint(), I overhauled my code to have [https://paste.kde.org/pkt2o2ifh this].

 * After a deeper look at my logic of getTangentPoint(), I overhauled my code to have [https://paste.kde.org/pkt2o2ifh this].
-* My mentor has confirmed that my logic is a step int the right direction and has suggested that I use github and email more including IM/IRC.
-* Starting to design unit tests for this getTangentPoint() function.
-= Tuesday June 30th =
-* Filled Student evaluation form today.
-* Working on unit test for getTangentPoint() member function.
-* Some work in progress available [https://paste.kde.org/pvnynjgvt here]
-= Wednesday July 1st =
-* Sick day:I have not been able to do any work because of the symptoms of malaria I've been experiencing since morning.
-* I've developed the unit tests for the getTangentPoint() in librecad/src/main.cpp and LibreCAD builds well.
-* Next step is running the code to see the results from the function.
-= PRE MIDTERM EVALUATION SUMMARY=
-I was rather off to a slow start for GSoC 2015 coding due to my final year management project. However, I've written the getTangentPoint() member function for the LC_Hyperbola  and I am currently designing appropriate test cases to ascertain the effectiveness of getTangentPoint() function. When I've perfected these test cases, anyone will be able to run these tests after compiling LibreCAD by ./lc on the command line in the unix/ directory.
-= Thursday July 2nd =
-* Sick day: Have not done any work today. Currently on medications.
-* Managed to post my pre midterm evaluation summary to my development logs, BRL-CAD mailing list and cc'ing my mentors in LibreCAD and BRL-CAD.
-* Updated my LibreCAD [https://github.com/Ngassa/LibreCAD repositories] too.
-= Friday July 3rd =
-* Sick day: Haven't been able to do any work due to illness.
