Definitely. When I started soldering in 1978, the short era of homebuit computers already was coming to its end. It was a great time for Nrds. There were no rules and everybody built or programmed something as he thought it was right. And then you presented your results to other nerds who immediatly started improving it or discussing it to death. The first software I bought was a debugger and I remember calling the man who wrote it all across the US to talk about some changes. My parents grounded me and took away the computer when they got he telephone bill.
I used the spare time in my room to build a small Z-80 computer from my parts box
"I don't know, extraterrestrial?"
"You mean like from space?"
"No, from Canada."
If software development were a circus, we would all be the clowns.
So we are looking at the revers engineering of a major users engine that is so unwieldy it can no longer be supported. It take a minimum of 3 months to change and test a rule!
As it is a very large core requirement it will be done by the IT team. They are proposing Java over a Hadoop data store using Drools as the rules engine. As my experience in this area is extremely limited I put it to the hive mind.
Is Drools a viable rules engine for a very large and complex set of rules. I fear it is like Biz talk is to ETL, designed for "power users" to maintain!
Never underestimate the power of human stupidity
Yeah - you'd think they picked this so they can hire a very specific person. In my chemist days, there would be employment offerings that were extraordinarily specific in nature. To find a citizen with these mandatory traits would command a princely sum and they'd offer chump-change. Along comes the H1b visa*.
* now they had an employee who they could underpay and who couldn't legally change employers or quit.
Define what the rules should be and see what that engine can do ?
I mean you do have requirements and it should not be too hard to get the technical details of the things that should fulfill these, right? Ask a demo, have them prepare a technical document with the solutions.
You're right to ask questions and to be sceptic about something that is complex. Perhaps it's a good tool, perhaps not, it's up to them to prove it
Anything that is unrelated to elephants is irrelephant Anonymous - The problem with quotes on the internet is that you can never tell if they're genuine Winston Churchill, 1944 - I'd just like a chance to prove that money can't make me happy. Me, all the time
Over here in Japan traffic lights are horizontal with red on the right. In areas with heavy snowfall they are vertical with red at the top.
Back in my country, they were also vertical.
I think some countries have horizontal ones with green on the right, like the US and Thailand IIRC. I hope there are no places with red at the bottom.
If there are international drivers licenses, surely there should be an international standard for traffic lights too? Things can get confusing if you travel frequently and are colorblind. Of course since we can't agree on which side of the road to drive on, it is not really surprising.
The ones in the US that hang overhead are good because it is hard to miss seeing them. I don't see what advantages horizontal ones have, maybe cost? (Cheaper to mount because they can be lower?)
The colored arrows are particularly treacherous. Here there are green arrows to indicate which directions you can go. Australia also had red arrows too to indicate which directions should stop. And yellow arrows for trams (or are there? I don't remember that well)
Personally I prefer roundabouts. There aren't any here, just millions of unsynchronized lights without sensors that make you stop every 100m even when there is no traffic on the cross roads. Maybe they want to teach us patience.

No yellow arrows for trams, but those tram specific ones are illuminated in T shape. Traffic signals and rules involving trams here could be somewhat complicated:
Hook turns: If you want to turn right, be on the left lane[^] because trams are worshiped here. You'd occasionally observe one noob sitting confused in the hook stop and a bunch of angry drivers literally forcing his car to move ahead with the pressure waves generated by their incessant honking. And some would actually drive past him on his right side (illegally), leaving him in the hook stop so that the traffic on the west->east lane to start honking when they get their green signal.
Tram traffic indicators:
I've seen them to be illuminated red[^], amber[^], AND white[^], and I think that white mean that trams can go (not sure why isn't it green). And the there are signals indicating that trams don't have to worry about the traffic signals displayed, like in this mother of all traffic lights[^].
