Q: Green fields, and the white board - what is too broad?

I've been accused of having questions that are too green fieldy and not white boardy enough. What does this mean and why do those questions get closed?

user55340

@gnat there's the green field and white board Q&A from meta. Suggestions welcome.

@RobertHarvey that rest one is real easy if he would have read the document I referenced... Chapter 6 ( ics.uci.edu/~fielding/pubs/dissertation/evaluation.htm ) would be what he's looking for.

This isn't so much "white-boardy" as it is "blue-sky-y". There are entire careers built on trying to solve this problem - you're gonna have to narrow it down a bit. — Shog9 ♦ 33 mins ago

@MichaelT That's not what Greenfield means. "Restraints imposed by prior work" means that you can't build an office building on land already occupied by a railway. It doesn't mean there's no restrictions; it doesn't mean "pie in the sky." There are always constraints imposed by new requirements; greenfield simply means that you don't have to consider existing system constraints in your new design.

A: Where is it implied that REST is not based on HTTP

Architectural Styles and the Design of Network-based Software Architectures, Chapter 5, Section 5.3.2 reads, in part: REST does not restrict communication to a particular protocol, but it does constrain the interface between components, and hence the scope of interaction and implementat...

Took me about 5 minutes to find it, in a document the guy says he already read.

Guess I've asked some bad questions and cant make a question right now, so I'll just ask here and check back later:

I'm trying to set my DNS A name record to pair my doma name with my website's server IP

But the site is hosted on a certain port of the server, and the A Name record only allows the IP (no port), so.. doesn't the record somehow need to know to direct traffic at the right port? for example I'm serving on port 6070, how do the DNS settings work properly if the port isnt included in the A Name Record?

I'd usually just redirect traffic from the domain name to the right IP/port, but since I need to use SSL, I think I have to link the domain to the server IP via the A Name records instead.

Thanks ahead of time to anyone who takes the time to respond :)

@jt0dd You ought to look into Network Address Translation, which is typically handled at the router. And I'll echo amon's comments - that question would definitely be off-topic for Main.

@Shog9 consider that prior cleanup of a similar troublesome tag took us over two months. And, if you take a look at three other tags complementing that "bucket", it can easily take about a year.

@GlenH7 some neat engineering application lenses I've stumbled across... telecentric.

user55340

Telecentric lens

A telecentric lens is a compound lens which has its entrance or exit pupil at infinity; in the prior case, this produces an orthographic view of the subject. This means that the chief rays (oblique rays which pass through the center of the aperture stop) are parallel to the optical axis in front of or behind the system, respectively. The simplest way to make a lens telecentric is to put the aperture stop at one of the lens's focal points. An entrance pupil at infinity makes the lens object-space telecentric. Such lenses are used in machine vision systems because image magnification is independent...

The image of the subject is the same size as another subject if they are the same size in real life (the distance from the media doesn't matter).

user55340

@AshleyNunn there are also lenses that work the other way - things in the distance are larger than an object in the foreground that is the same actual size.

Unless someone does it first, personal-projects is a meta tag. Its unnecessary. It doesn't mater if its personal, or homework, or professional. If its a good question, its a good question. Kill the tag?

There is only one singularly tagged question... that should be closed and deleted.

Q: Where are some good places to announce a personal programming project?

Where can I advertise my personal projects for free? Other than hosting services. It seems to get followers on github you need them to already know about what you're doing from another source.

personal-projects

user55340

There's also hobby-programming, but that has quite a few more singularly tagged questions.

Robert Harvey

I don't really share your point of view but I don't think it's a good idea to debate on this. Thank you for your help, i'm fixed now. — ibi0tux 2 hours ago

Why did he ask if he already knew the answer?

user55340

@RobertHarvey confirming beliefs or design?

user55340

10:48 PM

Second opinion... just happened to be one that didn't agree with the one he had in his mind and went on to design from.

Robert Harvey

Mmm. He's probably "Code First." Us old database guys think differently.

user55340

And to an extent, it shouldn't matter too much. The question from an SE perspective is was it a good question, did it get a good answer? If the answer to both are 'yes', then thats good.

Robert Harvey

Is there some sort of SQL CONSTRAINT that would do it?

user55340

@RobertHarvey not sure off hand.

user55340

Btw, that grails question that just got posted is possibly a good example of how a question can be whiteboardy rather than blue-green sky-field.

Q: Grails Angular JS Simple

Could you just begin an Angular project with Bower/Grunt/NPM give it its own directory and the whole nine yards ... and then just throw it in your Grails directory somewhere with the index.html page to be rendered as a static HTML file by a Grails controller? So basically all the Grails app does...

angularjs grails

user55340

Its a design question, I don't think its too broad. It could have been written as a wide open one, but its posed with a problem and a design that is likely answerable.

Robert Harvey

He put his Google Search in the title. Always amusing, when people do that.

user55340

yea... titles are things I (and I'm sure other people) keep forgetting about when searching.

user55340

That said, its not an awful thing to do in that if there is a dup on the site, and you actually read that list, it would have a not bad chance to find it.

angularjs grails

Now it will actually look coherent in a Google Search result.

user55340

Yep. That works for a title.

user55340

Half the point I'm trying to make there is that its possible to ask these very broad questions that remain white-boardy and aren't too broad for the site if you ask it in a way that would actually be something you would have on a whiteboard.

Robert Harvey

Maybe this is a good example to cite.

So I've seen three types of jobs so far in my job search...

Enterprise webby CRUD, custom desktop/device apps, and embedded.

user55340

There are people who ask questions like "I'm trying to do a search like google" and effectively leave the whiteboard empty in the question. This one doesn't.

Robert Harvey

The embedded job is local. All the rest are 2 hours commute. Still looking.

Have been wondering what kind of "networking" I should be doing.

@MichaelT Programmers is not the only site that has the "blue sky" problem.

Any time the phrase "Best Practices" appears in a Q, you know you're in trouble.

user55340

@RobertHarvey No, its not. And gnat jumpings on best practice questions when he sees them. The thing is that I think a higher percentage of our too broads are blue sky compared to SO.
