I've started responding to recruiters with this list of requirements

Company Requirements

I'm definitely not looking for work. However to provide some helpful guidance for hiring like-minded engineers, I would only consider working for a company if it met these requirements:

  1. Fewer than 250 employees.
  2. Concrete, measurable plan to increase the number of women and minorities in engineering roles.
  3. Commitment to using and contributing to open source.
  4. Collaborative, friendly atmosphere where pair programming is encouraged.
  5. Meaningful work with clear linkage between work and company goals.
  6. Demonstrated commitment to ethical business practices, e.g. B corp certification.

Example for DISPATCH_SOURCE_TYPE_MEMORYPRESSURE (Mac only, since 10.9) ... Since we share code between iOS and mac, I'm trying to be a good system citizen and reimplement the equivalent of UIApplicationDidReceiveMemoryWarningNotification on the Mac.
NSString *const PSPDFApplicationDidReceiveMemoryWarningNotification = @"PSPDFApplicationDidReceiveMemoryWarningNotification";
// Test with sudo memory_pressure -l critical. Don't forget to re-set afterwards!
__attribute__((constructor)) static void PSPDFInstallLowMemoryNotificationWarningMac(void) {
static dispatch_source_t source;
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
source = dispatch_source_create(DISPATCH_SOURCE_TYPE_MEMORYPRESSURE, 0, DISPATCH_MEMORYPRESSURE_WARN|DISPATCH_MEMORYPRESSURE_CRITICAL, dispatch_get_main_queue());
dispatch_source_set_event_handler(source, ^{
dispatch_source_memorypressure_flags_t pressureLevel = dispatch_source_get_data(source);
