Big bosses coming? Вам не сказали того что вы ожидали?

Тогда не отчаивайтесь, это случается часто и повсеместно,

Случайно я даже нашел сходство с текстом одной и всем известной песни, какой?

Resolving of true method via objc_msgSend and within IDA for arm binaries

As you know Objective-C is full (80%+) of calls which are made through the help of  the internal objc_msgSend method.
This is not a problem unless you would like to make some reversing for a good reasons :)
and at this point, knowing what method is actually called - kind of a key.

Not a problem any more, just have a look on helper IDC script for IDA which makes situation more transparent and works directly over arm binaries, so it makes from kind of unknown:

__text:000036B8 02 F0 92 EC                       BLX             _objc_msgSend

something more obvious for the method call name:

__text:000036B8 02 F0 92 EC                       BLX             _objc_msgSend ; @selector(getVertexSize)

Just note method name where app will land at.

Selling copy of ... sample, ripple HD (?) effect

Ripple effect looks quite interesting and there are some questions how to do such.
Apple has released the own sample, available from GLCameraRipple and this is not the end of the story: some guys have decided to sell the sample and more - it has been accepted by Apple and App Store, just here - Ripple HD
(verified by shaders :) - 100% the same, including "Copyright (C) 2011 Apple Inc. All Rights Reserved." )

PS if you are interested in "how to implement?" - just look for the full sources at the sample page from Apple, YUV -> RGB is there and more, like simulation of UVs via

runSimulation and rippleTexCoords

Nothing to say more from the technical side of the Ripple Effect implementation question.

Understanding Verilog Blocking and Non-blocking Assignments

One of the best and detailed explanation of such important and to the good extend, complex topic - so far, been found here: Understanding Verilog Blocking and Non-blocking Assignments

quite old from the date but so useful in many aspects, must read.

Bash'ing in Parallel

When you need to process many items (like I had to process for my video from the previous post - 4817 initial pictures) you would better think about how much time it might take. In my example, even knowing that 4817 pictures with such perfect but not yet well threaded to use all CPU cores tool as imagemagick takes about 2 second per picture , total time is kind of nightmare to wait for.
So, as I am processing on Linux and with script - here is the trick to utilize all local and remote CPU cores even from BASH script and(!) minimum changes required:
Instead of traditional for many years:

for i in `find . -type f -name "file*.png"`;
do 
do_view_port.sh `echo $i | sed -e 's/\.png//' -e 's/^.*_//'`
done 

Where I process all .png files in the folder and one by one with my do_view_port.sh, "magic" script with needed actions, just get GNU Parallel (which is IMHO best by now) and do very minor changes:

find . -type f -name "file*.png"  | sed -e 's/\.png//' -e 's/^.*_//' |
parallel -j+0 --eta do_view_port.sh {.}

where it start to be cleaner for the look and faster ( in my case: 7.65x ).
Just note {.} which represents a "current" arguments...

So and in total - this, kind of one change, allowed me to finish needed changes within as much as 23min (instead of 175min or close to 3 hours ) 

PS: I personally liked this free ETA, as always, meaning time yet to go/Estimated Time to Achieve :)
