Any investigation by a government department produces multiple different conclusions, depending on who requested the report... (/s)
Remember that the flypast rules were designed for airshows, which are completely different from stadiums.
The first rule in road maintenance is to keep water away with ditches and drains, to prevent formation of gullies and dongas. It needs more than a grader to fix that kind of infrastructure...
P.S. I'm reading a book about Roman Roads, and after 2000 years the bits still in good condition are...
The transition from winter to summer can be very gradual in Cape Town, and further cool conditions are likely this week. A well developed front is predicted for Sat 17th, bringing some rain, and possible snow over the high mountains. This chart shows the extremely cold daytime temperatures...

During the lockdown I got to watch some channels which I would not normally bother with. This example is a purely mechanical defrost timer, with all of its pros and cons:

3. The frost has to be melted 2-4 times per day, otherwise it blocks the system.
4. Melting of frost is done with a...
I got a chance to read the full article. These 'white hat' hackers are extremely thorough at indentifying all of the vulnerabilities in a system. It's a pity this only happens after they are deployed at scale in a live environment.
The whole point of the expensive controllers was to connect to...
FTFY. Broken last digit in URL.
