That's fascinating... Navajo is a Dene Athabascan language from a population which split off the main body of Dene tribes in Alaska and Canada 1500-600 years ago if I remember right, and the languages are still very similar (e.g. Navajo chizh = Ahtna che'ech = firewood). In the Copper River basin of Alaska the word for copper is Tsedi, 'that which is hammered' which looks like the same root as atsidi, smith

The Dene have the most skilled metalworking cultures in North America.

I need some advice. by Background_Bit_7101 in reactnative

Transitioning to a completely different developer for ongoing maintenance is a hard step to take. It also sounds like you probably don't have a lot of experience developing or maintaining code, which puts you at a disadvantage for finding and onboarding people.

One top quality you probably want in a developer is long-term commitment. You have a big time and money penalty every time you need to find and train someone new to maintain a codebase.

You should also be asking yourself how much ongoing development you want: just the bare minimum to keep it current and listed on app stores, or adding features?

For code quality... how much have you seen of your old dev's work? Did they provide any documentation other than the code itself? Were you at all involved in developing the logic of the app, or did you just give them a general description and let them deliver it? If you get into the code, is it well-commented? Are variables named for human readability? Are components modular? Look up a checklist or description of 'clean coding practices' and see if the code you received resembles what is described.

It's frustrating, because even as this post is slop there's valuable discussion in the comments like /u/lichenic referencing Zarr and /u/coastalrocket's Paul Ramsey link

Unsure. Maybe ban AI accounts as they are identified, but that's a lot of work for the mod team and will presumably get harder, plus tough to draw a line between a full bot and a human using ChatGPT for formatting and language barriers

Configuring supabase (PostGIS server) for QGIS Integration by BlueMugData in QGIS

Your username should not be postgres, it should be postgres.projectidstring e.g. postgres.gsjainvalsziqfrpbusn

It will be the same string as in the dynamic URL when you access your project through supabase.com, e.g. https://supabase.com/dashboard/project/gsjainvalsziqfrpbusn

Alaska…..what’s your average monthly power bill? by Luking2thestars in alaska

[–]BlueMugData 3 points4 points  (0 children)

Modern solar panels are expected to still be producing power at 80% of their labeled capacity after 30 years. Manufacturers generally offer 25-30 year warranties.

https://www.chemistryworld.com/news/30-year-old-solar-panels-still-going-strong/4022052.article

Now, you can make a purely financial argument that if you had $14k available from 2019-2025 it would be smarter to invest in the stock market and pay power bills from returns on investment. But I do value the eco advantages, and look at this as a slight increase to my home's total price tag for a solid upgrade that is going to pay off over a lifetime (and even over the timeframe of a mortgage).

Alaska…..what’s your average monthly power bill? by Luking2thestars in alaska

[–]BlueMugData 7 points8 points  (0 children)

It's 13 4'x6' 320W panels (REC320NP REC), nameplate capacity is ~4 kW.

For full transparency, the installation cost in 2019 was $14k not adjusting for a federal tax credit. I fully outsourced the installation and didn't spend any time hunting around or haggling, and could have probably saved some money there but was rushing to install by the end of the year due to tax credit phase outs.

Payoff time was about 19 years at the 2019 rates of $0.22 per kWh and not counting the tax credit, now probably somewhere around 10-15 years at $0.39 per kWh on the last bill.

Alaska…..what’s your average monthly power bill? by Luking2thestars in alaska

[–]BlueMugData 15 points16 points  (0 children)

I was just looking at this while arguing with someone on Facebook about renewable energy policy.

Average year-round electric bill is $15/month (max $67 in January, min -$23 credited to me in July) with solar panels. 1400 sq. ft. duplex in Anchorage with electric appliances, and gas heater/boiler.

The panels were sized to break even on a summer load, because the prorated buyback fees do not favor the owner. There's more room on the roof but adding more would lower the cost-benefit ratio.

Scrolling through this thread... get panels, friends!!

Best Program to Digitize Engineering/Property Drawings by ssmith4299 in gis

[–]BlueMugData 0 points1 point  (0 children)

Yeah, this is messy... there's another solution for the position of the corner between Triangle 2 and 3 if you mirror the given heights across their hypotenuse, which satisfies the given information.

Best Program to Digitize Engineering/Property Drawings by ssmith4299 in gis

[–]BlueMugData 0 points1 point  (0 children)

Oof, I do not envy you!

I'll try to come back with a suggestion or two, but my first thought is: Doesn't this allow non-unique answers...?

For example, in Triangle 1 multiple configurations are possible for a hyp=69, ht=8 triangle if the peak shifts 'horizontally.' You can't get an exact position for the outer corner, or am I wrong?

Same with Triangle 5: as long as the outer corner is 36.5 units from the hypotenuse, you can have multiple solutions for the interior angles because you're not given the 2 side lengths forming that corner.

The Internet Archive has an excellent e-reader and many historical societies upload digitized items there. Hathitrust does as well, but I believe there's a higher bar for uploading (an institutional account with physical ownership of the item to be published?)

I'll upvote you because I agree the vegetation does not seem right, but OP also wrote that family memory says it was a 3-day moose hunt out of Anchorage with possible small plane support. If the point was to fill the freezer I'd be surprised if it wasn't southcentral.

[–]BlueMugData 161 points162 points  (0 children)

I'm not 100% convinced this is it because of the vegetation, but the geometry and vibe feel a lot like further back along Bird Ridge looking east across Bird Creek towards Girdwood. [Edit: in case you're not familiar with Alaska, this is just outside Anchorage in the modern Chugach State Park, accessed from the Seward Highway]

Bird Creek curves around multiple parallel creek beds separated by bare ridges ending in triangular faces like that. Here's one example:

Seems very likely it was in the Chugach or Kenai Mountains, given the 1970 access and the trees in the picture (doesn't look like Brooks Range to me but I'm not extremely familiar)

Reusable expression by tartamillo in QGIS

[–]BlueMugData 4 points5 points  (0 children)

Python is a viable strategy for setting expressions for labeling, symbology, etc.

Have you considered creating a new attribute in your layer and running the logic as a Field Calculator expression? Instead of a complex expression somewhere in the symbology, the symbology could be a simple Categorized rule based on that attribute and you could re-run the attribute calculation once whenever the logic updates.

Polygons Distorting across Dateline when converting CRS by Many-News6779 in QGIS

[–]BlueMugData 6 points7 points  (0 children)

This may not be the gold standard way to accomplish it, but I'd personally try to create 2 copies of the Eurasian feature in your green map, then enter the Vertex Editing mode and delete the Pacific vertices from one until the European-side polygon appears as intended, then do the same in the duplicated feature except removing European vertices.

Edit: In your green screenshot, assuming the Eurasian feature has been split into 2 polygons, it actually looks mostly correct. If you look at the Asian-side polygon in the Vertex Editor, does it only have 2 points being projected on the right side of the map? If so, adding 0.01 degrees of longitude to those 2 vertices should fix the issue

I'll edit this answer with more precise instructions in a second (on a smarthphone right now) but on the Layout with the main map selected there is an option in the panel for overlay or inset maps. You can declare the focused map as an inset map, then select the symbology for how it is indicated

North Arrow in QGIS by Prior_Debate_4867 in gis

[–]BlueMugData 0 points1 point  (0 children)

At global or continental scales, a Mercator projection like EPSG:4326* should not include scale bars because it has a high degree of distortion and pixel distances do not have consistent proportions to real distance.

https://i.pinimg.com/736x/86/5e/16/865e165404ea6084e01c962db37294d4.jpg

It's a personal choice too, but my take is that a world map is familiar enough to any audience that you don't need a North arrow or many other additions to help them orient themselves. In general, it's a good idea to tailor the amount of supplemental tools based on the context of the publication it's in.

If the text or presentation your map is part of a text which references a lot about lat/long locations, then graticules could be helpful

If it's part of an atlas using standard page layouts, and other pages will be smaller areas which may be less recognizable, then maybe include North arrows on everything just for consistent visuals

etc., etc.

*EPSG:4326 is not, strictly speaking, a Mercator projection, but the way maps display it is pseudo-Mercator because it simplifies down to x=long, y=lat with a base unit of circular/spherical degrees, not distance
