k tech tree

Thought experiment:

Which k primitives can be implemented as k-strings, reasonably efficiently, with a handful of 'native' built-ins?

Not verified to be in dependency order yet... may depend on the choice of 'fundamental' primitives. Need to do speed tests too.

k9 syntax (download via Shakti). Got a better way to write one? Feel free to comment, you'll be credited!

1. Place homebrewupdate.sh where ever you like, I use ~/bin/homebrewupdate.sh
2. Place the .plist file in ~/Library/LaunchAgents and update the path to your bash script
3. run launchctl load ~/Library/LaunchAgents/com.jb510.homebrewupdate.plist or whatever you've named your plist file.
4. check launchctl list | grep jb510 to see that it's running

Note: You might need to chmod +x homebrewupdate.sh

Note 2: you can run this manually to test your script ~/bin/homebrewupdate.sh

Future: Update this to also update casks https://github.com/buo/homebrew-cask-upgrade or using brew cask list | xargs brew cask reinstall

OS X Screencast to animated GIF

This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.

Instructions

To capture the video (filesize: 19MB), using the free "QuickTime Player" application:

static BOOL PSPDFIsDevelopmentBuild(void) {
#if TARGET_IPHONE_SIMULATOR
    return YES;
#else
    @autoreleasepool {
        // There is no provisioning profile in AppStore Apps.
        NSData *data = [NSData dataWithContentsOfFile:[NSBundle.mainBundle pathForResource:@"embedded" ofType:@"mobileprovision"]];
        if (data) {
            const char *bytes = [data bytes];
            NSMutableString *profile = [NSMutableString new];

Make it real

Ideas are cheap. Make a prototype, sketch a CLI session, draw a wireframe. Discussions around concrete examples, not handy-waving abstractions. Don't say you did something, provide a URL that proves it.

Ship it

Nothing is real until it's being used by a real user. This doesn't mean you make a prototype in the morning and blog about it in the evening. It means you find one person you believe your product will help and try to get them to use it.

Do it with style
