2016-11-29 Firefox on macOS

To have Firefox look a little more at home on macOS, check out the following addons:

I've also noticed that Firefox 50.0.2 sometimes crashes when disconnecting the external monitor from my 2016 MacBook Pro. After restarting, it brings up the Restore Session screen with the "Well this is embarrassing" message. To turn this off, go to about:config, search for resume_from and double-click on the value browser.sessionstore.resume_from_crash so it's set to false.

2016-11-14 Questions when looking for a coworking space

I've heard the figure that every four hours, a new coworking space is created. Personally, I've got a permanent desk in a coworking space, which allows me to put down a decent monitor, some personal stuff, a USB hub with a decent keyboard and mouse, et cetera. If you're also looking for a nice (semi-)permanent desk somewhere, here's a list of questions to get a feel of the place:

  • Who is the day-to-day floormanager?
  • Who has access to this room?
  • Are desks and chairs supplied, or should I bring my own?
  • Do I get an ethernet cable? This is very important because WiFi can be iffy.
  • Is there a lock on the door? What quality is the lock and the door itself? Can I get additional keys? Can I change the lock if necessary?
  • What's the speed of the internet at work times? If they don't know, ask whether you can place high-quality Skype and Facetime calls.
  • What's the level of sound during the day? Are there people here whose main job it is to call around?
  • What kind of businesses are next to this room? Above and below it?
  • Can I enter the building 24/7 or are there limits?
  • Is cleaning included? How often is this done? What's the cost?
  • What's the cost of parking a car? Are their spots to charge an electric car?
  • Any additional costs for internet, heating, et cetera?

Be sure to write down these answers. I've had the unfortunate situation where an office manager would give me a room next to a studio, and forgot to mention this. Luckily a desk was available in another coworking room.

2016-11-08 AutoLayout in a playground

What got me confused today, was how to play with AutoLayout in a Playground. The trick is to first create a main view, akin to the view in a View Controller, that is sized with a frame (without constraints).

After that's set up, add subviews that use AutoLayout. The following works for Xcode 8.1:

    import UIKit
    let view = UIView(frame: CGRect(x: 0, y: 0, width: 500, height: 500))
    view.backgroundColor = UIColor.white
    view.layer.borderWidth = 2.0
    let licensePlateView = UIView()
    licensePlateView.translatesAutoresizingMaskIntoConstraints = false
    licensePlateView.backgroundColor = UIColor.gray
    licensePlateView.leadingAnchor.constraint(equalTo: view.leadingAnchor).isActive = true
    licensePlateView.topAnchor.constraint(equalTo: view.topAnchor).isActive = true
    licensePlateView.widthAnchor.constraint(equalToConstant: 200).isActive = true
    licensePlateView.heightAnchor.constraint(equalToConstant: 50).isActive = true
