Check status of the Tampa Crosstown Expressway’s reversible express lanes in Ruby. Tampa–Hillsborough Expressway Authority doesn’t offer an API, so it uses Nokogiri to scrap the official website’s status display.
#!/usr/bin/env ruby
require 'rubygems'
require 'open-uri'
require 'nokogiri'
doc = Nokogiri::HTML(open('http://www.tampa-xway.com/'))
img_src = doc.css('img.closures').first['src']
if img_src.match /West/
puts 'Westbound'

Using C99 for clever and non-fragile UITableView configuration. Allows implicit defaults. Copypasta’d from a screencap tweeted by @jonsterling: http://twitpic.com/80uyfp
typedef enum {
kAccomplishmentTitleSection = 0,
kAccomplishmentCategorySection,
kNumberOfSections
} NESTemplateEditTableSections;
static NSString * const kCellIdentifiers[] = {
[kAccomplishmentTitleSection] = @"AccomplishmentTitleCell",
[kAccomplishmentCategorySection] = @"AccomplishmentCategoryCell"

Less-hacky approach for configuring table views that are mostly static, but have some sections/cells that are conditionally visible.
// in -viewDidLoad
self.cellOrder = [NSMutableArray arrayWithObjects:@"Address", @"Hours", @"Call", @"Get Directions", nil];
if (foo) {
[self.cellOrder removeObject:@"Hours"];
}
if (!self.location.phoneNumber) {
[self.cellOrder removeObject:@"Call"];
}

I love^W**HATE** date programming on iOS.

NSPredicate *predicate = [NSPredicate predicateWithFormat:@"(weekdayFrom <= %d OR weekdayTo >= %d) AND ANY location.resourceUri like %@", weekday, weekday, self.resourceUri];
Hours *hours = [Hours findFirstWithPredicate:predicate];

if ([hours.hourFrom intValue] <= currentHour && [hours.hourTo intValue] >= currentHour) {
