For the science of Sociology, should the findings and recommendations of these scientists be given the same weight in the decision making process of political bodies as Physics or climate change scientists? Should it be more? Less?

Nice! I've wanted to become cave certified but I'm still trying to master my buoyancy. Don't want to be kicking up dirt in that environment haha.

Visited Argentina and specifically Cordoba not too long ago. Miss it a lot, didn't think I would see a reference to it here.

Its a mess of a network and you can probably find other groups of interest in those subjects elsewhere. Its filled with nutjobs and extremists and shock posts.

Some people have some ballistic opposition to it, and if you are even remotely heard of being near it then they will block or ban you. Some will even go so far as to make in their personal mission to "cancel" you in all aspects, although to be fair they typically only do this if you actually say something terrible.

Go on git or google sometime to see the witch hunt of Fedilab about simply not implementing a hardcoded block to Gab. They didn't advocate it, nor advertise it, the developer just didn't think it prudent to make decisions on behalf of their users.

To be fair I'm all for freedom of association, and that includes from it, so that's their right... however if you crucify too many people about not sharing your personal jihad, you'll end up being as ostracized as those you seek to exile.

@freemo

Lol good luck with that. You are either with or against in this environment. No room for nuance.

One day. One day I won't be too retarded to understand this. It accomplishes quite an amazing feat - creating interpolated data on the edges of a map where you have none, based on what is surrounding it. Not a perfect solution, but one that has some amazing potential applications, not just in GIS.

A couple of other notes -
+ Its atrocious to not handle the case that both comparison sets are the same - in which case one can go from n ^ 2 to n / 2, where n is the number of geometries to compare.

+ Warn. Warn about many, many things. Its not that its "wrong", just that the user (which might well be me, doesn't have a clue what they are actually doing)

+ Find some way of avoiding loading everything in memory. This is an underlying QGIS issue... it seems that opening up an .getFeatures() method corrupts another that is still open before.

Not a Git master yet, but here is my GitHub, where I will be posting my generally hacky and work in progress QGIS tools.

Currently working on my Near Matrix tool. Near has a long and sordid history in GIS as being the trolliest tool to paywall in Esri's ArcGIS. (although Erase can give it a run for its money sometimes).

Near, for reference, merely takes a set of geometries and compares it to another set of geometries (I'll go into more detail on other posts) finding the shortest distance between them.

QGIS has a couple of built in routes one can go down on this path, one of which is the "Nearest Neighbor Analysis", which does exactly this - but only for points, not lines or polygons, which limits its helpfulness.

Another route would be to use its GRASS module plug ins, one of which is v.distance. These are excellent tools, but you really need to pay attention to the input and outputs. They tend to be a bit "clunky" from my experience.

Instead, I'm building my own, which does what I need, as well as something extra that none of these tools does in a manner I appreciate - visually generate the line between the two geometries in question.

I wouldn't be supervised if QGIS has this natively soon (after all, all I am doing is using the underlying methods the main developers have exposed) but until its available in LTS I'll keep using this one.

Some things still left to do:
+ Better handle geographic coordinates (if these come in, the distances will be functionally useless, better either use some insane math or error out to the user)
+ Better handle NULL geometries (these are not going to play well with anything)
+ Create another field and dump the unit in them. (Experience with GIS tells me that a free floating "distance" double field will eventually be sent to someone with no idea if it is in feet or meters)
+ Create some fancy pants SVG icon for it, so I can get away with not useing the default.
+ Actually learn Git so I'm not constantly deleting / reuploading to the web interface

For some reason I can't get "tang" out of my head when I read this

@freemo

What did you try? If Soylent doesn't work out then I'm curious what other options there are.

Going to try Soylent again... last time it didn't end well. Its been a few years, so here is hoping that they fixed whatever caused that.

@pschwede

Well, I mean it was bombed and the inhabitants mostly evacuated... so we are kind of arguing semantics here. It doesn't exist in continuity in the same manner as say, Berlin. Its not all gone either, and I did mention the Russian name, which is also the name of the region.

Well roughly tied supporting and more nuanced views. Appears one person voted against it

Sad to see him go. He was definitely someone who did his best to keep the series alive in the spirit of his father

@snow

Noise. That's the dirty secret Trump uses to his advantage... You don't ever have to deal with political fallout if you keep dropping political nukes. Everyone just keeps reprocessing after the shell shock and they never get a coherent thought out of it.

The only way to beat it is to ignore it.

This has applications in GIS, especially around things like circulation elements city planners use to plan out road placement and design.

Fun fact - Konigsberg no longer exists, it was destroyed by the Russians in WWII and now exists as the Russian exclave of Kaliningrad.
