But if you don't want to see those advertisements, and for some reason you don't want to use Private Browsing (like me), than you're out of luck (by default). There's no normal way to enable this feature without the use of Private Browsing (or use an adBlocker add-on for Firefox). Thankfully, Firefox uses a config module in which you can tweak almost everything.... including the Tracking Protection.
This was one of those moments that I needed a lot more millimetres on my camera. This photo was made with the Fuji 55-200mm x-mount lens (@200mm).
A 600mm or 800mm would have been nicer, but also a little more expensive.
The original mechanical shutter gives you a or minimum shutter speed of 1/4000second. This is not that fast, compared to the average dSLR, where 1/8000 second seems to be the standard. Another 'problem' is that you can't use fast lenses (f/1.2, f1/4) in (bright) daylight, without the use of ND-filters.
This week, I ran into an annoying feature regarding the Apple iOS Personal Hotspot function of my iPhone 5s. I had to do some software testing with various WiFi clients. This worked fine, up to the moment that new devices ran into connectivity problems.
The new devices could connect, but got a message that there was no/limited Internet connectivity. Checking the IP address of the devices showed that they had an 169 address assigned.
So the iPhone wouldn't give new IP addresses to the new devices. Earlier devices that connected correctly could reconnect without a problem though.
It turned out to be a 'normal' DHCP problem. The IP address scope on the iPhone was depleted.
The iPhone has a small DHCP address pool that can give out 16 addresses (172.20.10.0-172.20.10.15). Of these 16 addresses are 3 taken by the network, broadcast (172.20.10.0 and 172.20.10.15) and iPhone itself (172.20.10.1). Leaving 13 addresses for other devices.
In normal situations, this shouldn't be a problem, but when your testing stuff, you can run into a shortage of IP addresses. Besides the shortage of addresses there is another challenge; no way of altering the DHCP lease time, or even clearing the issued IP addresses.
The lease time for the DHCP address is approximately 1 day (85536 seconds), as shown by a little network traffic capturing below.

There is a function to reset the network settings on the iPhone, but that just clears everything regarding (wireless) network settings, but it doesn't touch the DHCP service in the iPhone. A reboot of the iPhone doesn't do the trick either. So you just have to wait till it clears automagically.
So there is room for improvement......
The new iTunes iOS app that goes with the Apple Radio launch annoys the heck out of me. For some reason the GUI designers (and marketing peoples) think that the Apple online services are the only thing you'll ever need. This results in an iTunes menu bar where 80% is useless to me.
