There's a Youtube channel called Computerphile that has done a few videos on graph theory and the kind of problems it is used to solve. Might be worth hunting some down if you want to apply this to a real-world problem, as I find having an actual thing to solve is the best way to getting to learn a new technology.
Don't forget about relationship direction when working with graph DBs. Your Cypher query is bi-directional but the LINQ query is uni-directional. I really like Cypher and neo4j but haven't had much reason to use a graph DB recently Fun stuff though.
What I was alluding to was that no direction for the relationship is specified in your Cypher query. This means that outgoing and incoming relationships will be searched in the match. So for example:
//Matches both p1 and p2
//Matches only p1
Un-directed was probably a better word to use than bi-directional. My bad. Since it's common to think of directed relationships as p2 "not knowing about" p1 since you can't traverse to p1 directly from p2, I figured I'd point out this little nuance of matching in case you weren't aware. The LINQ example would only match p1 so I thought maybe there was some misunderstanding.
Thanks Jon, for the clarification: I still can't see any differences between my translation of the Cypher into C# ... both are really two queries; I didn't chain the C# queries because I wanted to make the code more explicit for display here.
I think I see your point about bi-directional: the second query is looking for connections to Joe.

Don't get me wrong - the daughter is the primary culprit, and her mother deserves blame as well.
But Roblox is designed for kids, and it's at best unethical to allow them to do that. If gambling is "restricted" with gambling companies required to warn people if they are spending too much too quickly (and they are in the UK at least though it's as useful as a chocolate teapot) then allowing kids to generate that kind of debt is a disgusting practice IMO.

I was actually referring to a certain fruit company in this case.
Having so bad security that the daughter could change the fingerprint for appstore is remarkable, imao.
On that other system I have Family link installed. Any time my kids try to install something that costs money, I have to ok it. On my own phone.
I also get the possibility to limit the time spent on these gadgets, and I can easily block apps I don't agree with. On distance.
The kids learn quickly and don't click anything that's an In app purchase.
If you setup your phone to use TouchID you need to enter your passcode to add fingerprints on your phone.
You can then allow TouchID to authorize Appstore. For that you need to authenticate once using your AppleID.
If you later decide to add another fingerprint to the TouchID service you only need to authenticate yourself using your Passcode. You don't need to authenticate yourself using your AppleID.
Having seen the way my 3-year old grandson plays with any family member's mobile phone, and in the past my granddaughter on some Disney online game, I totally agree. Children have no idea what's going on in these devices, or the costs associated with them.
Eight year old's should not have an iPad, iPhone, etc etc etc. In my ludite strong opinion, anyone under 13 shouldn't.
They should be out playing, or reading, or doing something that properly develops their minds and souls. For those of you old enough, I'm sure you can remember occupying yourself with all sorts of fun things that didn't involve staring mindlessly at a screen and clicking on things with your thumbs.
The fault here lies in the broader scope of our society in general and the bullshit that we call social media, entertainment, and so forth, that we have been led to believe is good for our children and has some actual value as an adult.
And don't give me this bullshit that they need a head start in today's world. I didn't touch a computer until 7th grade, and it was a teletype machine that saved programs to tape - punch tape!!!
I am from the generation who went outside to play.
Luckily I had my own NES back then, and a little later I got my own PC with games such as Age of Empires and The Curse of Monkey Island
I had friends who had limited computer time, like an hour or two a day, I never understood why.
I have a cousin who is the same, but his sister still likes to go outside.
Maybe the "problem" is that not everyone likes to go outside and do stupid stuff like run after a ball and be social
