"Landmark Computer Science Proof Cascades Through Physics and Math:" [^] Quote: n 1935, Albert Einstein, working with Boris Podolsky and Nathan Rosen, grappled with a possibility revealed by the new laws of quantum physics: that two particles could be entangled, or correlated, even across vast distances.
The very next year, Alan Turing formulated the first general theory of computing and proved that there exists a problem that computers will never be able to solve.
These two ideas revolutionized their respective disciplines. They also seemed to have nothing to do with each other. But now a landmark proof has combined them while solving a raft of open problems in computer science, physics and mathematics.
At last Alan Turing can get some rest (because this proof possibly solves the "halting" [aka "decision"] conundrum).

What an amazing age we live in:
- Science (and math) is moving ahead in leaps and bounds
- and humanity is moving twice as fast ... albeit in the opposite direction.

Imagine having been born in 1895. By age 50, you would have gone through WW1, the Depression, and WW2.
But I would agree that many things are headed in the wrong direction, wisdom among them.

I was singing in a church choir, doing the Mozart "Coronation Mass". The conductor made some remarks about what some people managed to achieve at an age of 23 years. I couldn't resist raising my hand and remark: "Yeah, and at your age, he had managed to be dead for five years!"
The entire choir, and the conductor, went remarkably quiet after my comment.

This is common knowledge that I remember first reading about in Dawkins' The Blind Watchmaker, back in 1986, so some knowledge-winning, it seems, is more a case of looking for ideas to put one's name on, so that people in the future will believe they are yours.

Java's split() behaves very weirdly. I was needing to split on a caret ^ and
"Test1^Test2".split("^") was throwing an error. A quick google search says that special characters need to be escaped. No big deal, I do
"Test1^Test2".split("\\^") and still same error (invalid escape sequence characters...)
I google for a java fiddle and test it in the fiddle and it works great. So, I check eclipse and find that I have java 1.8 so I include that in google.
Luckily I find a new response that says to use java.util.regex.Pattern.quote(). So, I try
"Test1^Test2".split(java.util.regex.Pattern.quote("^")); and that actually works.
The documentation says string.split() has been around since Java 1.4 so why in the world would eclipse behave different than other java compilers?

StackOverflow[^] seems to think your second code block should work.
What does java.util.regex.Pattern.quote("^") return, and how does it compare to "\\^"?

Ya, 95% of the search results all say that should work, and it actually does in a java fiddle.

It was something like "\\Q\\E".

Regex vs non-regex? Your last example is rather explicit. The previous ones...well, somebody clearly doesn't like them. For some reason.

Unless it has changed recently, eclipse is not a compiler, it uses the installed version of Java to perform compiles.

So I wasn't the only one thinking that... yeah, it's an IDE afaik.

Yes, which is what I said in my OP but I did not say it clearly, I guess.

Hi all, I'm in the process of replacing my home router which has a private ip address of 10.10.1.1.
I'd like to run both routers in parallel for a while until I'm happy with the new kit.
I've connected the new router to the existing one and given it an ip address of 10.10.2.1. As an incremental migration stage I've configured one of my devices to connect to the new router ( which it does ) but the device cannot see / ping devices on the existing subnet. If I take the old router out of the equation and connect all devices to the new router all obviously works perfectly but I'd like to run both in parallel until I'm happy with the new kit. Suggestions ?

Keeping it simple? Keep the old router next to the new one but used the new one. If relevant, load test it. If satisfactory you can move the old router a few feet further away - maybe unplug it.
This makes your test clean and sure (as sure as you can be with electronics these days . . . keep the old one as a ready-backup!).

You can try creating a bridge. If you have two adapters in a connected PC you can connect one to each router and then bridge them. Some routers will allow bridging if you connect the other router to it but it isn't always available these days.

I've seen that with some newer routers, the reason is not any lack of the equipment's capabilities, rather dumbed down settings that dont allow bridge mode setup.
I somehow did get a newer ASUS [without any bridge mode settings] to work (by turning off it's DHCP server setting) except it refused to accept a subnet mask different to factory default (in any mode) ...despite a setting for that being there.
- result: it does bridge (fully works), but that router itself is invisible on the network.
Equipment is getting better, it's the settings that are getting worse, waaaay worse.
-- happening everywhere, not just routers.
after many otherwise intelligent sounding suggestions that achieved nothing the nice folks at Technet said the only solution was to low level format my hard disk then reinstall my signature. Sadly, this still didn't fix the issue!

If DHCP activated... which pool are you giving in each router?
Are you using only one router as default gateway? or using each router in each subnet as such?
Which subnet mask are you using in the devices?
If the default 255.255.255.0 (/24), then you won't be able to see the devices on the second net. You should change to at least 255.255.63.0 (22), but I would just go for the easiest solution and use 255.255.0.0 (/16)
Can a device in the first subnet see the device on the second one?

Subnetting is the first thing that came to my mind. Once the subnet is fully accessible, what determines the route is the gateway address.
