"c'mon," he ordered. "soldiers of the king, at the double! and the witches – where are the blasted witches?" three junior apprentices presented themselves. "i've lost my wart!"

i am extremely happy to announce that i have successfully completed my gsoc project! i would like to take this opportunity to thank the community for this wonderful learning experience. it has really helped me to add a new dimension to my knowledge while at the same time introducing me to the world of open-source projects. most importantly, i would like to thank my mentor reini urban (rurban) for the tremendous help he offered me, ever since my first contact with the community. as a matter of fact, without his ideas and invaluable guidance, completing the project would have been an impossible task. i would also like to thank my co-mentor bruce gray (util) for guiding us throughout the project and providing us with valuable inputs to overcome the many hurdles we faced. in this blog, i will attempt to summarize the work i have completed through my project. my project's primary objective was to improve the performance of the method signatures . my project was divided into three tasks:- zyroz's blog 1 comment read more gsoc 2014 - report 12 submitted by zyroz on wed, 08/13/2014 - 17:14 hey everyone! this week i ran the bench test on the three tasks to verify the performance gain. but due to my slow machine, i could only generate varied and unreliable data. however, rurban confirms that all the tests are passing and the branch pcc-gh1083 is ready to be merged for the parrot release scheduled on 19 august. also, he soon plans to test it with a 32 bit machine as well. zyroz's blog login or register to post comments read more gsoc 2014 - report 11 submitted by zyroz on wed, 08/06/2014 - 18:11 hey everyone! i will be sharing what i have completed this week. last week, i had mentioned that i would be fixing further problems in my branch to optimize pmc2c ( https://www.parrot.org/zyroz10 ) . i am happy to share that i have successfully completed this work and believe that the issue gh #1083 ( https://github.com/parrot/parrot/issues/1083 ) is now resolved. to elaborate on the work done --- a couple of weeks back, i started by omitting the obj check in the callcontext attr accessors in include/pmc/pmc_callcontext.h . zyroz's blog login or register to post comments read more gsoc 2014 - report 10 submitted by zyroz on wed, 07/30/2014 - 16:49 hey everyone! this week i completed the part of my task that required me to export the internally needed callcontext vtable methods ( https://github.com/parrot/parrot/issues/1083 ) . these exported methods are now included in src/call/*.c to improve the performance, since these methods are now being directly called. in the previous week, i had finished fixing the headers to omit the obj check for callcontext attr accessors . but i had made these changes manually by fixing include/pmc/pmc_callcontext.h . zyroz's blog login or register to post comments read more gsoc 2014 - report 9 submitted by zyroz on wed, 07/23/2014 - 18:13 hey everyone!
