  1. Falls hier jemand zufällig bei https://coord.info/GC4V8MY nicht weiter kommen sollte... hab das gerade mal für einen Kumpel ausgetüftelt. Sehr schön gemacht. Die Ziffern ergeben sich aus der Anzahl Sterne heller als 3 mag.

  2. “Handala hacking collective says it 'compromised' secure US navy phones, updated target bank for #Resistance Axis”

    “Iranian hacker collective Handala announced on 8 May that it breached the ‘secure phones of officers of the terrorist US Navy regime’ and began transferring updated US#Navy #coordinates in the Persian Gulf to regional resistance forces.

    The group said it had mapped updated locations of US military gathering points across the Gulf region, describing the newly acquired data as a ‘target bank’."

  3. When the #Internet just isn't #confusing enough, cue GeoJSON: a delightful buffet of geometric buzzwords 🍕🥨 that are as riveting as watching paint dry. The #IETF somehow found this chaos worthy of standardization, because apparently, the world needed more ways to complicate #coordinates 🌍🤦.

  4. → GBIF Geocoder: using GBIF to find places on a map
    iphylo.blogspot.com/2026/02/gb

    “The idea behind the "GBIF Geocoder" is that GBIF has a huge number of geocoded specimens, and hence if you are looking for coordinates for a locality there is a good chance that somebody has already found them. So, all we need to do is search GBIF for specimens with localities that match the place you are trying to geocode.”

  5. I'm an #engineer, not an #artist. But every so often, I need to use graphics-related tools for something I'm working on. Today's example was trying to lay out some control panel #graphics, and I was using #Inkscape on #Debian.

    What I did: created a circular object

    What I wanted to do: when I select that object and type values into the #coordinates boxes, the circular object moves so that its *center* is at the specified coordinates.

    What Inkscape actually does: moves the object so the top-left corner of the object's bounding box is at those coordinates.

    Really not helpful when you want to #align multiple objects to the same #center.

    Do some searching, find #forum posts of others asking how to do this exact thing. Answers range from "select the object and open the #XML editor..." to "do this specific thing which doesn't appear to have existed in the UI for a decade", to people suggesting workarounds (you need a #workaround for what must be an *extremely* common workflow?).

    One workaround: "just create a #guide, move (or maybe it was 'align') the object's something-or-other to the guide". The word "guide" does not occur in the UI, FAQ or in the basic documentation for Inkscape. Searching for it is troublesome because of all the web pages that have "guide" in their *title* rather than their content.

    Lots of other discussions with links to pages on the Inkscape site which are now 404.

    Where's that "FFFFUUUUUUUU..." meme when I need it?

  6. Ah, yet another profound revelation from the "Revolutionary" team at Cloudflare: #DNS LOC records are apparently both "weird" and "wonderful." 🎉🌈 Who knew that scattering #server #coordinates across the internet could be so exhilarating? Tune in next week for more #groundbreaking #discoveries like the thrilling intricacies of watching paint dry. 🖌️😴

  7. For the nineteenth are a set of map using different coordinate system projections of Natural Earth railway data naturalearthdata.com/

    The four maps represent points on the oblate-spheroid that is the Earth on a surface. The first uses latitude and longitude in °, the rest are in meters. The second is commonly used on the web, the third a projection for Europe and the final is the UK Ordnance Survey map projection.

  8. #Rotating a #Point about the origin, through some #Angle θ is something that is taught in school #maths class, usually in #CartesianCoordinates, by multiplying the #Coordinates by a the rotation #Transformation #Matrix. What’s not generally taught is that you can apply the same transformation to any #Function y=f(x). All you need to do is replace
    x by xcosθ + ysinθ
    and y by -xsinθ+ysinθ.

  11. Очень люблю эту табличку и регулярно её показываю особам, бездумно копирующим координаты из Гугла

    I really love this table and regularly show it to people who mindlessly copy #coordinates from Google

    [the math is way over my head, hence the wiki page leak, but a good read nonetheless]
    “HIGHLIGHTS:
    • Hexagonal multi-structural elements enhance Earth's surface modeling precision.
    • Integration of indexing and conversion rules improves geospatial data computation.
    • DGGRID implementation shows increased precision in raster and vector data modeling.
    • Addresses limitations in existing software for Earth observation data.
    • Pioneering approach expands geospatial data processing applications…"

    [still an excellent teaching aid, and who doesn’t like the idea of mangling a grapefruit with a rolling pin?! (turnips not so much…) ~wink~ ]
    “Development in long-range travel and the growing importance of the Arctic and Antarctic regions make it necessary to understand how maps may be misleading. Experiments with a grapefruit illustrate the difficulty of presenting a true picture of the world on a flat surface and it is concluded that the globe is the most accurate way of representing the earth...”

    I also love this image from 1921 (!), still useful today, and when I used to teach a little it was part of my coursework… we are so visual…

  15. Good morning! Or afternoon or evening, depending on where you are in the world. Did you know that #Godot allows you to create libraries of functions for #shaders that you can later link to your shading language script without the need to copy and paste their code every time? We'll demonstrate this with a few simple examples, and then we’ll apply this knowledge to create another shader effect using the #polar #coordinates. #GodotEngine #Godot4 #GodotTips #devlog

  16. CW: [Puzzle][Just invented] A game on an infinite board. Is it playable?

    The #board is the #integer #grid, Z x Z; the #places are the #coordinates (x, y). (0, 0) is blocked.

    All places are #teleport stands: for all k, x, and y, (kx, ky) is a zero-move from (x, y). Alternatively, (kx, ky) is "the same place" as (x, y).

    Given a sequence of n >= 2 places, p_1 = (x_1, y_1), p_2 = (x_2, y_2), ..., p_n = (x_n, y_n): p_n can *be attacked* from p_1, and vice-versa, if and only if (x_1 * ... * x_n) + (y_1 * ... * y_n) > 0.

    The #game proceeds as follows:

    1. The board starts empty. Each #player starts with 20 pieces (all identical).
    2. By their #turn, each player either:
    - Puts a piece on a #place (only one piece per place); or
    - Moves a piece one unit on the x or y direction (no diagonal moves), from any teleport point attainable from the current place; or
    - If there's an adversary piece that can be attacked from a player's piece, the player can attack and take the adversary's piece (move and take, like in #chess).
    3. The game must allow at least 10 turns for each player. After that: if a player has no pieces on board, they lose. The winner is the last player with a piece on board.

    Now the question: Is this game playable at all? Can it be fun, even?
