Just installed RVM.

Message from RVM after installation:

* To start using RVM you need to run `source /Users/antkong/.rvm/scripts/rvm` in all your open shell windows, in rare cases you need to reopen all shell windows.

OSX terminal and .bashrc

When I create a new tab in Terminal, the new bash shell does not automatically execute the .bashrc file.

I added this to my .bash_profile to fix the problem:

[[ -s ~/.bashrc ]] && source ~/.bashrc

-s here means if the file exists and not of size 0

Health system of USA is odd. For example, Oregon uses a lottery based system to allocate health care coverage - a scarce resource - to its citizens.

From Wikipedia:

New enrollment in the program was closed from mid-2004 until early 2008, when a lottery-based system was introduced. Tens of thousands of Oregonians signed up, competing for 3,000 new spots in the plan.

It is basically saying that the policy makers have given up on trying to design and implement a system to allocate the resource based on any meaningful and measurable metrics.

Two ways to build file names

Use pathWithComponents or stringByAppendingString

// 1 NSString* txt_file_path = [NSString pathWithComponents:@[file_unzip_location, @"content.txt"]]; // 2 NSString* txt_file_path = [file_unzip_location stringByAppendingString:@"content.txt"];

[anthonykong]

Basename-equivalent in Objective-C

Use lastPathComponent

NSString* filepaht = @"/tmp/mypath/myfile.txt"; NSString* filename = [filepath lastPathComponent];

Drone Warfare

This is a public lecture by investigative journalist/activist Jeremy Scahill:

https://www.commonwealthclub.org/node/65484

Very chilling account of the impact of drone warfare on the targeted population as well as the democratic values of USA.

From another perspective, here is an interview of General Norton Schwartz:

Harry put the drone warfare question to him near the end of interview.
