@enderland There's one or two on there, which is sufficient. Doesn't need to be piled on. One or two are enough to send the message

user41796
It sounds like this opinion is not particularly popular, but I don't think it is okay. Stack Exchange is a place of learning; you shouldn't have to worry about being judged for asking "dumb questions" later down the line. Moreover, this would exacerbate the issue of users keeping multiple accounts, one for asking questions, and one for providing answers. I've already seen this a number of times on SE. I think users do it because they appear more knowledgeable with less questions asked. — MikeS 2 mins ago
 
user41796
8:18 PM
He's a 101 rep user, so can't put a counter answer in on that question.
 
user41796
Yes, I'm arguing for more playing with the collider score, but I think it's fair to allow in a valid counter point and see what happens with it. I invited him to The Whiteboard in a reply comment.
 
jozefg
jozefg
@MichaelT That's a good idea..
 
user20683
@GlenH7 Mike should have enough
 
user55340
@jozefg The problem wasn't the "stock 5h energy" it was the "mandatory 10h days that you would otherwise fall asleep during for a prolonged time."
 
user41796
@WorldEngineer No answers, no questions - 101 rep comes from association bonus only. If he had an answer in somewhere else on the site, I would have upvoted it just to get him past the 10 point site rep threshold for the protection

so do you folks get overtime pay if you work more than 40 hours?
I've just got the option to work up to 50 hours (with OT pay)
idk what is standard for others?
 
user55340
@WorldEngineer The protection doesn't take the association bonus as part of the amount to get past it. To the protection, he's got 1 rep.
 
user41796
@enderland In a previous life I got straight time for my OT pay, but was paid OT. Nowadays, I don't get the opportunity for paid OT
 
user55340
@enderland We did... but 4 months of 50h days... you just are drained. It doesn't help get stuff done. That messed up bug in october was in part from that... July, August, September, October.

also, since it has been reddited it's not quite the same thing as collider masturbation. ~800 views in 2 hours are like genuine - compare to masturbated top question that got just 1,4K in 10 hours (99,99% lemmings)
@MichaelT well whatever as long as mods have an eye on particular question, I am OK with that. Bad thing about collider is it harms questions in a way impossible to control neither by community nor by mods, those that get in mods hands are not like that by definition
 
user55340
@GlenH7 and @gnat I think either of you could re-protect it...
 
user41796
I have flagged a few comments that really weren't happening. So it's being actively tended

@gnat Yes, I've read that. There is some Bayesian formula for evaluating things like number of stars in an Amazon review that involves something like calculating the probability it really is 5 stars given both the number of reviews and the values. Giving rep to an answer based on some similar formula involving number of views would help a lot - except the rules for SO are already impossible to explain.

Pale Horse Rider - When the Lamb opened the fourth seal, I heard the voice of the fourth living creature say, "Come and see!" I looked and there before me was a pale horse! Its rider was named Death, and Hades was following close behind him. They were given power over a fourth of the earth to kill by sword, famine and plague, and by the wild beasts of the earth. — gnat Jun 8 '12 at 11:17

@MichaelT did you try the trick with cliff voting between 0 and 3:00 GMT? Graph could look the same, only with double amplitude
Sep 1 at 10:47, by gnat
@MichaelT did you notice that "cliff" questions allow one double their daily voting limit? I mean, cleanup script runs 3 hours after "server day" starts, and killer votes cast during these happy hours, stop counting towards the limit after the script deletes questions so that one can vote further

Also, keeping people who are experts in their field is critical to the success of any SE site. I haven't seen anyone leave because a few questions became problematic. But people do leave if they are constantly harassed.
deleting my MSO account might be an option to consider to push through that hotness correction request. Indeed, it's the only thing I really need from MSO, the only thing that permanently, as they say, "harasses" me both at Programmers and Workplace

@Brant nah, but I'll probably just use that
I recall using it ages ago and finding it easy enough not to really need an abstraction
but now that it's been years I figured maybe it had gotten fancified (which some reading on google suggested to be true)
at which point I would rather an abstraction make it simple

There's also Web SQL Database, but I can't imagine you'd actually want to use it.

@Brant No you're thinking of Caché

Heh.
I guess it depends what you're storing. localStorage limits you to 5MB per domain and you're dealing with strings. It probably wouldn't be hard to wrap JSON serialization/deserialization around that.
I'm not aware of any libraries that bother with any higher levels of abstraction, because blah blah offline webapp oxymoron just restore state from the server etc

My polling question of the day: I've got a couple of classes with a many-to-many relationship. I was about to give one a collection of the other, but decided that it's too common for someone to later invent an attribute on the link itself, which would then be an API breaking change, so I changed to a collection of link objects. Anybody have any thoughts?
@WorldEngineer That would have come across so much more diabolically if I had noticed it had left protected status.
@Brant Awesome! What have we just proved again?
 
Jimmy Hoffa
Jimmy Hoffa
Elaborate... many-to-many so..

class Foo { List<Bar> knownBars }
class Bar { List<Foo> knownFoos }
that's how you were going to do it and then decided your codey sense was tingling?

@JimmyHoffa Well, I'm not sure if Bar would have a list of known Foos. And it was going to save properly to the database.
@JimmyHoffa Are you implying this is obviously stupid?
 
Jimmy Hoffa
Jimmy Hoffa
Oh so it was more like...

foo1.knownBars.Add(bar1)
foo1.knownBars.Add(bar2)
foo2.knownBars.Add(bar1)
foo2.knownBars.Add(bar2)
 
psr
psr
@JimmyHoffa Pretty much.
 
Jimmy Hoffa
Jimmy Hoffa
@psr what I just defined above probably would set off alarm bells to everyone here (which I'm sure it did for you as well), but the other many-to-many I just suggested is far more common, and...fairly harmless...depending on the scenario
 
user55340
10:55 PM
Part of the fun with many to many is the dependency cycle.
 
psr
psr
@JimmyHoffa As far as harmless, what about the issue of when we decide that we need the FooToBarConnectionStrength attribute?
 
Jimmy Hoffa
Jimmy Hoffa
@psr Do foo2 and foo1 have references to the same bars or are they values?
 
psr
psr
@JimmyHoffa References.
 
Jimmy Hoffa
Jimmy Hoffa
@psr I'm not sure I understand what you mean there, are you referring to an attribute of the connection between foo1 and bar1 that would be different from the connection between foo2 and bar1?
 
user20683
FooBar Connection...sounds like my internet lately
 
Jimmy Hoffa
Jimmy Hoffa
11:00 PM
@psr This is the scarier part about these types of relationships. At this point I like to look at putting some kind of events on bar so that when foo1 changes something, foo2 can adjust if need be
 
psr
psr
@JimmyHoffa Yes, instead of saying my foo1 merely knows about bar1 and bar2, we've decided it can know about bar1 with a 50% connection strength. (In short, yes). I've had people throw attributes on the connection pretty often over the life of a code-base.
 
user55340
The connection itself should be an object then.
 
psr
psr
@JimmyHoffa Don't need that yet in my case.
 
Jimmy Hoffa
Jimmy Hoffa
That's...strange... I would put that in the foo as a Dictionary<barId, strength> if not creating the link abstraction objects you referred to
Though the concept of it seems very strange to me, I'm not used to having properties of the relationships between objects
 
psr
psr
@MichaelT Right. In my case, the attribute hasn't actually been added to the link - yet. My point is, if it ever gets added it will break my API later if I don't make it an object now.
 
Jimmy Hoffa
Jimmy Hoffa
11:02 PM
It feels a little brittle to place attributes on that...
 
user55340
@JimmyHoffa I've put additional columns on the relationship tables...

Graph database
A graph database is a database that uses graph structures with nodes, edges, and properties to represent and store data. By definition, a graph database is any storage system that provides index-free adjacency. This means that every element contains a direct pointer to its adjacent element and no index lookups are necessary. General graph databases that can store any graph are distinct from specialized graph databases such as triplestores and network databases. Structure Graph databases are based on graph theory. Graph databases employ nodes, properties, and edges. Nodes are very simila...

@psr class Foo { List<Bar> knownBars; Dictionary<barId, relationshipDescriptor> relationshipInfo; }
but I'm not sure that's the right way
I'm just throwing out an alternative
having a class probably makes more sense
or just List<Tuple<Descriptor, Bar>> knownBars
but in any case I'm referring to the semantics of it that feel strange and brittle to me
@MichaelT relationship attributes in a database should be modeled like you refer to if their is variance and possibility of 0 relationships then you add columns to your bridge table to identify the relationship info
but object modeling, I would rather know information about the objects than their references because the references shift often, and indirection class does give you this but I'm wondering if it might be better for your foos to hold the information, the link objects you reference there are only pertinent to that given foo, so perhaps that info should be on that foo

Just think of modeling a family as a graph. The link holds the type of relationship "sister, brother, father, mother, son, daughter"

if you had for instance
class Foo { List<BarRelationship> knownBarRelationships } you've effectively got a list of objects that have information specific and only relevant to this *instance* of Foo, so why doesn't this instance of Foo hold the information perhaps? Iduno. Perhaps it does make the most sense just both ways seem strange

@JimmyHoffa Not sure what you mean with rather know about objects than references.

I get that, how about this:

class Person { List<Person> Family; Dictionary<Person, PersonType> RelationshipsToMe }
@psr I mean in that image above, I don't like having properties on the lines between the nodes; I would rather have the information living on the nodes than the lines
It seems strange to me to attribute facts to the lines rather than the nodes
 
psr
psr
@JimmyHoffa Any reason?
 
Jimmy Hoffa
Jimmy Hoffa
the lines shift and change
you reference these things, then those things, then some other things, having facts about those references feels like you could have more information churning
but iduno
Like I said, just throwing out some thoughts here. The link object route is probably what I would do
 
psr
psr
@JimmyHoffa Even if the nodes are more stable than the lines, when you merge the lines into the nodes they will acquire the instability.
@JimmyHoffa Though in my case I don't have attributes on the relationship - yet. I just fear I will later and I think refactoring to add them will be easier with the link objects. But someone here may have gone down that road and have some insight.

Aye, I would probably go the route you're mentioning. I just like to play devils advocate whenever I analyze an approach, looking for other options. Like I said before, you could always have the information added to the Foo later as a dictionary, or is that the "breaking your interface" you were talking about?
 
psr
psr
I'm also not clear in my head on whether having a link object helps at all with the Foo having a collection of Bar and Bar having a collection of Foo.

that's a completely different problem
and that is helped by an abstraction, except it's more like a bridge table: It knows foos, it knows bars, but foos and bars don't know eachother.
 
psr
psr
@JimmyHoffa It is what I'm talking about, but I haven't thought at all about whether that is an issue with your implementation.
 
Jimmy Hoffa
Jimmy Hoffa
nah, either route doesn't cause that problem, though if you do need circular dependency like that you want a totally different approach
circular dependency as a problem trumps many-to-many problems in that solving the circular dependency solves many-to-many, but not the other way around\
 
psr
psr
@JimmyHoffa That is what I meant, I just hadn't thought about if I was just kicking the circularity down the road.
@JimmyHoffa Incidentally, what approach do you use for circular dependency. I can't recall trying it.

class FooBarRelationship {
    private Dictionary<Foo,List<Bar>> foosBars;
    private Dictionary<Bar,List<Foo>> barsFoos;
    GetBars(Foo); GetFoos(Bar); AddFooToBar(Foo, Bar); AddBarToFoo(Bar, Foo);
}

class Foo { Foo(FooBarRelationship fooBars) { _fooBars = fooBars; } }
class Bar { Bar(FooBarRelationship fooBars) { _fooBars = fooBars; } }
(something like that off the top of my head)
inversion of control it
keeps the two-way relationship reconciliation and safety away from the foos and bars etc, ideally they won't get the FooBarRelationship object and shouldn't need it; those who consume Foo will consume the FooBarRelationship and ask it/maintain within it the info it needs about the relationships
That leaves foo and bar down to just managing themselves and their relationship management to their consumer; inverting the control of the relationship management
Also helps keep your stacks shorter
No foo calling to bar calling to foo calling to bar
 
psr
psr
@JimmyHoffa I hadn't considered that at all, but had considered Foo and Bar delegating to FooBarRelationship, mostly so that the code throughout the system dealing with the Foo Bar family mostly didn't have to look at weird FooBarRelationship objects.
If FooBarRelationship develops exciting attributes later in its life people would be dealing with it directly anyway, though.

Ideally the relationship is a simple to use object, and foo and bar may know how to take each other but only by being passed to them as method parameters by their consumers. This still isolates foo and bar from relationships which keeps them from referencing a foo that references a bar that references a foo to a bar
