Even though the server hosts the public code, there is no reason for the public code to have access to server-side stuff directly

From a security stand-point, I would say you wan't to restrict to a minimum what clients can do with the server :)

@Malachi @Marc-Andre Why bother even editing it back? OP states code doesn't work, may as well vote-to-delete because, at this point, regardless of whether we delete it or they do it's going to count against them now because Malachi edited it.

@EBrown It's less true here, but the OP could always decide to go back and edit working and re-open the question. I'm really not against voting to delete the question. Until a question is deleted it should not be vandalized for any reason.

EBrown

@Marc-Andre The problem is that by rolling that edit back, @Malachi just created much harsher punishments for the OP if they get the question deleted either by themselves or another.

SE takes edits into account for question bans, just like answers and even comments to an extent.

Marc-Andre

And?

It's working as intended I think

EBrown

Which means that by rolling back a question that should probably just disappear, we give the OP much harsher punishments

If we force challenge descriptions to be included in the question, why not also explanations for formulas?

200_success

Is that all? I'll just link to

Haversine formula

The haversine formula determines the great-circle distance between two points on a sphere given their longitudes and latitudes. Important in navigation, it is a special case of a more general formula in spherical trigonometry, the law of haversines, that relates the sides and angles of spherical triangles. The first table of haversines in English was published by James Andrew in 1805, but Florian Cajori credits an earlier use by José de Mendoza y Ríos in 1801. The term haversine was coined in 1835 by James Inman. These names follow from the fact that they are customarily written in terms of the...

EBrown

18:34

Well if we're going to require formulas to be described in the question, we may as well require algorithms and close most of the current active path-finding and sorting algorithm questions because they're unclear.

Vogel612

I didn't ever hear of the Haversine formula before today ... I've had two (or three depending on how you count) classes that dealt with algorithms ...

EBrown

So? Just because you don't use it doesn't mean we have to force the OP to describe it? We don't do it with anything else except challenges.

Vogel612

agreed. might as well be consistent...

EBrown

I literally typed 'haver' into my chrome bar and it autocorrected to 'haversine', it's obviously popular, just might not be for us.

But if we take 100 programmers, and 100 mathematicians, chances are more of the programmers know Djikstra than the mathematicians...

Just like more of the mathematicians will likely know the haversine formula than the programmers.

West Frisian language

West Frisian, or simply Frisian (Frysk; Dutch: Fries [ˈfris]) is a West Germanic language spoken mostly in the province of Friesland (Fryslân) in the north of the Netherlands, mostly by those of Frisian ancestry. It is the most widely spoken of the three Frisian languages. == Name == The name "West Frisian" is only used outside the Netherlands, to distinguish this language from the closely related Frisian languages of Saterland Frisian and North Frisian spoken in Germany. Within the Netherlands, however, "West Frisian" refers to the West Frisian dialect of the Dutch language while the West Frisian...

@Mast It doesn't make it unclear if it's omitted, in almost all cases.

rolfl

TIL ... there's yet another European language.

EBrown

And that's what the issue at hand was.

@EBrown No, but if combined with enough other problems it pushes it far enough into a grey area to acquire close votes.

And that line is pretty subjective.

EBrown

19:37

@Mast I fail to see what problems remain.

And I really don't like using VTC's in the gray area.

Mast

Not saying I'm doing it, just chalking down some conclusions from things I've seen.

But you should talk to the monkey, he has seen more.

I think I have a loose ground on my sensor.

Mast

@EBrown ...

That's a rookie mistake :-)

EBrown

@Mast I mean the graphs don't lie lol

Mast

@EBrown Eh, if I put a servo controller next to the sensor I'm sure I can get something similar.

EBrown

It's probably because the pin on the sensor itself is much smaller than the female connector I have it in, so it's probably not a great connection.

Mast

Interference.

EBrown

19:40

@Mast It's in a mostly isolated area.

Mast

Well, if the ground is loose, that's the likely culprit.

Just saying if it isn't, there's plenty of other things left to blame.

EBrown

@Mast You can see several of the dips.

Around 1700PM UTC I was playing with the sensors a bit which is what those jumps are.

Mast

Only one way to find out, check the wiring :-)

EBrown

And at roughly 0930 was when I calibrated sea level.

@Mast Yeah, I am gonna do some more soldering on it tonight/tomorrow.

I'll get the contacts solid then see what it looks like.

Right now I have it pretty well cobbled.

EBrown

@EthanBierlein See the graphs above for my progress. :)

Ethan Bierlein

@200_success Nothing is unclear about the formula. I VTC'ed the question because it was simply code and nothing else.

@EBrown Looks good!

I'm somewhat curious as to why the altitude graph dips, shoots up and then remains constant. Did you take the weather station for a drive?

Mast

@EthanBierlein Ah, yes, Rev 1 looks horrible.

Ethan Bierlein

Yeah, that's what I VTC'ed. I just wasn't around to see the revisions.

EBrown

@EthanBierlein No it was due to not having sea level configured properly.

Ethan Bierlein

20:10

Ah

EBrown

The massive upshot is when I configured sea level.

200_success

@EthanBierlein Still, closure seems a bit harsh, when the intended purpose of the code is right there in the title.

EBrown

@EthanBierlein The temp/humidity dips are because the ground on that sensor is low quality right now.

Mast

@200_success We should have an explicit rule against code dumps just to keep the quality bar of the site high enough, IMO.

Code dumps are unacceptable.

If people put such a low amount of effort in it, what are we doing it for?

200_success

I disagree. Downvote if you want, but sometimes a code dump is sufficient. If the title says "Base64 decoder", and the tags state the language, that's all I need to know.

Phrancis

@200_success Without regards for why the wheel was re-invented? We'll just get in the old problem of the answer mentioning something and the OP disqualifying it for previously undisclosed reasons.

@200_success Agreed. The op shouldn't have to add 'I have. base64 encoder in C#' just to make it 'on-topic'.

200_success

That's a quality issue that doesn't make the question off-topic.

EBrown

Exactly. A 'code dump' question like that invites down votes, but it's still perfectly on topic.

A: Haversine Formula in Clojure

Some broken, hypothetical, and some example code should not be reviewed because it's unproductive for everyone. They can be reviewed but it is harmful and/or unproductive. Code requests cannot be code reviewed.

@200_success Wow that's a huge improvement on the code!

Small nitpick maybe accidental, the inside of the top function should probably be indented two columns in instead of same column, at least that seems like the typical formatting with Lisp

  "Calcula distância entre duas coordenadas geográficas em metros"
  ([latlng1 latlng2]
  ; ...

Mast

@200_success I take offence to that, just for the record.

@EBrown In my opinion, reviewing questions which have no effort put forward by the OP is harmful to the site.

200_success

The OP was likely offended as well.

Mast

I stand by my point: Without regards for why the wheel was re-invented? We'll just get in the old problem of the answer mentioning something and the OP disqualifying it for previously undisclosed reasons.

And if there's no reinventing going on, it needs a description anyway.

200_success

Getting the site a reputation for having an unfriendly culture is also harmful to the site.

Mast

@200_success Mug can give you plenty of quotes saying we're not unfriendly, I'm not concerned.

200_success

20:55

Saying that we are a wonderful community does not necessarily make it so. In fact, it tends to piss people off when their observations seem to indicate the opposite.

Mast

All fun and games, but my point still stands.

EBrown

@Mast That goes both ways though, I'd bet if we search through deleted questions and comment threads we find plenty of instances that people think we're unfriendly. We need to take self-criticism. This is the same problem my workplace has right now, and we have a very high turnover rate when we shouldn't. But that's because we (here and there) don't take criticism well.

It's human nature to get defensive but we cannot just ignore the negative comments and focus on the positive because it's what we want to hear.

Mast

Perhaps I've been negatively influenced by my current companies culture as well, I don't know.

Anyway, long day tomorrow, so TTGTB.
