Android - Launcher Icon Size
...
I've created a script that exports Android launcher icons at velara3.com and from my research XXHDPI is 180x180 not 144. See developer.android.com/guide/practices/screens_support.html. Search on the page for, "180x180 (3.0x) for extra-extra...
Java's Virtual Machine and CLR
...dd two ints" where as CLR uses a polymorphic operand. (i.e. fadd/iadd/ladd vs just add)
Currently, the JVM does more aggresive runtime profiling and optimization (i.e. Hotspot). CLR currently does JIT optimizations, but not runtime optimization (i.e. replace code while you're running).
CLR doesn't i...
How to make execution pause, sleep, wait for X seconds in R?
How do you pause an R script for a specified number of seconds or miliseconds? In many languages, there is a sleep function, but ?sleep references a data set. And ?pause and ?wait don't exist.

Git Push Error: insufficient permission for adding an object to repository database
...han this is the problem.
It's happened to me in the past with some legacy scripts access our git repo and usually means a different (unix) user pushed / modified files last and your user doesn't have permissions to overwrite those files. You should create a shared git group that all git-enabled use...
What is the difference between LR, SLR, and LALR parsers?
...
The basic difference between the parser tables generated with SLR vs LR, is that reduce actions are based on the Follows set for SLR tables. This can be overly restrictive, ultimately causing a shift-reduce conflict.
An LR parser, on the other hand, bases reduce decisions only on the se...
Would it be beneficial to begin using instancetype instead of id?
...

OS X Terminal Colors [closed]
...
You can use the Linux based syntax in one of your startup scripts. Just tested this on an OS X Mountain Lion box.
eg. in your ~/.bash_profile
export TERM="xterm-color"
export PS1='\[\e[0;33m\]\u\[\e[0m\]@\[\e[0;32m\]\h\[\e[0m\]:\[\e[0;34m\]\w\[\e[0m\]\$ '
This gives you a nice...
How can I override the OnBeforeUnload dialog and replace it with my own?
...If you wish only for your unload event to occur I'd stick to plain ol' JavaScript for it.
jQuery doesn't have a shortcut for onbeforeunload so you'd have to use the generic bind syntax.
$(window).bind('beforeunload', function() {} );
Edit 09/04/2018: custom messages in onbeforeunload dialogs are...
Handling specific errors in JavaScript (think exceptions)
... Well Microsoft's C# certainly handles errors better than Javascript :P. Mozzilla added something like it to Firefox that's like that. Though it's not in the Ecmascript standard, not even ES6, but they also explain how to make it conform, though it's not as succint. Basically same as ab...
