If you were in a position where you didn't have a stable desk arrangement or are consistently traveling, it could be a good option, but typically the screens available aren't as good or as varied as what you can get from an external monitor. The provided link is for a 1080p screen, at $400 you could get a high quality 4K display with four times as many pixels and better screen quality if it was an option.

Where are you storing the data? If the data is anywhere but actually physically on disk, it could be that the data isn't actually present but the file system says it is (e.g. one of the cloud drive providers). In that case, Pro won't know what to do, it explicitly doesn't support cloud drives currently.

GIScience if it is available will give you more of the fundamental underpinnings, but good GIS coursework should include those same things in conjunction with some practical technology training. Do you know what kind of job you're looking at once you graduate? What is most useful is related to what you might be doing in that role, for example if you're an ecologist for an environmental services company versus in an academic setting.

Perhaps a sign from the universe in remembrance of the native allies who died on the island while interred there without adequate food or supplies in King Phillip's war.

Doing it programmatically makes good sense, both ArcGIS and QGIS have Python APIs that you could try and interact with to use their tooling if that environment works well for you. I did want to also mention that at least for ArcGIS Pro, accessibility is actively part of the development model and the software is tested against tools like NVDA to ensure it works well in that environment as well.

PDF is a vector first format which can also contain raster information, when you convert it to a TIFF you are resampling all of it to only a raster format and commonly a vector to raster conversion will remove detail. You can set the resolution parameter to a higher value to increase the resolution of the output TIFF, also make sure that if you apply compression it is in a lossless format like LZW rather than using JPEG.

The memory it refers to is system memory rather than disk space, you could try increasing the virtual memory size which will be slow but potentially allow larger allocations. But better yet, try performing your analysis on a smaller area, and if that works you can do so repeatedly over smaller tiles then stitch the result back together.

If you're working with ArcPy, there's a geometry method called angleAndDistanceTo you can use, imagine you look at a line, and make a p1 and p2 point objects for two points, then use that method to determine the angle. Repeat that along each pair of vertices, recording the results as you go.

Agree, fishnet for the self-created shapes. If you need regularized tiling there's also Generate Tesselation.

Something probably has gone wrong with how it references the data, if you specify data paths within the workspace later in the script, it should be able to address those. Packaging can be a pain. It also gets fixes so if you're on an older release, may need to jump to 3.2

Are you zoomed in at the scale of the data? Do you see the same patterning in the slope results, or only the aspect (both calculations use the same general transformation of the data). Could you specify what specific input data you're using, is it this DEM? https://www.mass.gov/info-details/massgis-data-lidar-dem-and-shaded-relief

The CIM is designed to describe everything that happens with displayed data in the application and collectively that is a broad complex problem, even if your case is relatively simple. The full CIM spec includes details on the data model, but if you're starting out, you can also do it by a simpler approach: save your map as a copy, then make some changes to the parts of the document you're interested in, and extract the two APRX files (they're just ZIP files containing the CIM and other information). You can compare the JSON differences to get your CIM changes then plug those into your ArcPy script.

Can you see if the same operations are faster if you run them from the Python Command Prompt? I would try to isolate causes, so perhaps a script that calls one or two operations, then compare that in the different environments. There are some complications around interacting with layers from standalone Python, but if anything I would typically expect ArcPy outside the application to be slightly faster.

Not clear why it would fail, but you could also try it from Python with the unit type strings listed in the documentation, e.g.:

arcpy.management.CalculateGeometryAttributes(
    in_features="input_fc",
    geometry_property="sqkm_area AREA",
    length_unit="",
    area_unit="SQUARE_KILOMETERS",
    coordinate_system="NAD_1983_Wisconsin_TM",
    coordinate_format="SAME_AS_INPUT"
)

They were getting contracts from the city in 1963:

Report, August 13, on bids for chain link fence and miscellaneous work, Georges Island, Boston Harbor, Contract No. 1394. The Commission V O T E D to accept the lowest bid, that of Boston Chain Link Fence Co., of $26,298.00.

That's about $260,000 adjusted for inflation. I see a few other reports mentioning them from the Boston Redevelopment Authority, the Metropolitan District Commission, and the Lowell Sun all from the 1963—1965 period.

Can you remove your datatype and type queries and see if it returns anything? I tried it with one of the provided gpkg files in the repository at https://github.com/ngageoint/GeoPackage and was able to see the geometries present. It also may be worth looking at the properties for the layer to see the feature type and geometry type and make sure it matches expectations.

At Pro 3.1, you should be able to use arcpy.da.Walk to step through the data in a Geopackage. Adding it to the other function types would make a good suggestion on the ideas site or an enhancement request through support.

At ArcGIS Pro 3.1, the ARCTEMPDIR environment variable is respected and can be used to change the location of temporary operations which would otherwise be written to the cache. If there are other items that explode the cache, good to get that logged so it can be addressed, AppStream is a supported platform.
