Software development in the real world 101: rewrites, and especially rewrites on a different language, are great ways to kill a project.

Internet tough guy.

If that let's you sleep better at night, sure. Stuff isn't hacked until it is.

Only because you don't know about them doesn't mean they do not exist. Have a look in here:

For instance these in 2017 https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Fwww.cvedetails.com%2Fvul...

The vast majority of these are for versions = 5.5, for obvious reasons as they've been EOL'd for years. Unless you're running some version of red hat that still patches their 5.4 installations, you're likely vulnerable to many of these.

That might be so, but the danger remains. It's not a problem until it is.

Not much more you can do other than that tbh. Explain what they're exposing themselves to, and let them make a choice.

Sites in php 5 are easily migratable to 7.x, obviously the earlier the version the less "easily". The vast majority of 5.6 code should run on 7.x with no issues. They did a pretty good job at avoiding big bc breaks.

Many of the vulnerabilities that have gone unpatched since 5.2 allow for remote code execution on the servers you're responsible for and perhaps sharing with different customers.

You only got out of the car to stretch your legs and rest 15 minutes every 5 or 6 hours of driving? While I admit I have also done that in the past, it's a very dangerous thing indeed to do, even if you just jumped in on the driver seat. Makes you prone to mistakes, longer reaction times and to misjudge situations. There are regulations in Europe on just how much professional drivers (eg lorry and to a less extent taxi drivers) can drive every day, for very good safety reasons. Even if you think you're doing alright please do make longer and more frequent stops, you might find yourself involved in a situation where reacting half a second earlier can save your life and many others around you.

I would disagree with this particular bit - 400km works at 3-4hrs of continuous motorway driving. You should really take a rest every 2 hours or so, especially on very long journeys.

Innit.

I wouldn't know, I speak from my own experience, nothing more.

It's a lot easier to get "road tranced" in the dark. Road lighting help a lot avoiding people falling asleep at the wheel.

That's true of a proper, structured programming language. The subject is dry and guaranteed to alienate even the geekiest among those children. Why on earth would you teach assembler or C++ to a kid? In the same way, would you teach an 8 year old Calculus, or basic math operations instead? A well designed subject that teaches them to rapidly write fun software in a simple and graphical manner would be a fantastic choice. There must be programming languages and environments out there that accomplish something like this. Hell, if you could design the subject around coding some very simple games in this fashion the little ones would love you forever. From there, in the same way it's done with any other subject, every year you can go a bit deeper into something more formal.

Kids do not need any computer literacy classes in the same way you didn't need any to operate a television or a vcr back in the day. People who need it are those who came in contact with a computer a lot later in life than nowaday's kids. That would be a complete waste of time.

Also, the region (I was born there) has plenty of experience on rolling out Linux on institutions through LinEx first (schools), then Debian itself (on the health system's IT infrastructure) later on. They were far from smooth at the time as mistakes were made, particularly when it came to re-educate and retrain staff. The region's government staff desktops is the last, and biggest, migration to make.
