  • The map is a community effort and the lack of social features, which caters to introverts, keeps focus on the end goal - an accurate map of the world. Other platforms are suitable for social activities and you can link to your OSM trace from there.

    Yes, seeing the trace geometry only with no map is a letdown. That’s why I suggested the visualizer in another comment. It would certainly improve the shareability of traces.

    OSM doesn’t produce any hardware. They are a wiki-based world mapping effort. In addition, they run a PNG tile provider (so you can embed their map on a website), an article wiki for how to edit the map etc. and the trace repository.

    You can use OSM and record traces using various apps mentioned on their wiki.


  • Come to think of it, OSM traces include timestamps and elevation for each recorded point, plus maybe other data from the uploaded GPX file. Maybe someone will create a Strava-style visualizer that serves HTML, SVGs or PNGs from trace IDs with a map, speed and elevation profile for easy sharing. Imagine your trace is https://www.openstreetmap.org/user/hagu/traces/11959920 and you change openstreetmap.org with perhaps openstreetmap-traceview.org and get a nice sharable overview that also has a PNG for preview on socials. Maybe even a page with a list of activities by user including kilometer stats by month, mode of transport etc.


  • That’s the neat part, there isn’t. Post about your trips where you want, you can then refer to the OSM trace.

    People have given consent for you to improve OSM with that data though. For example, one GPS trace can be pretty inaccurate (especially under a canopy where aerial imagery also doesn’t work) but you can compile a dozen (get them with a location-specific query) and get a very good average. You can message people about those edits, and add notes.

    Also, StreetComplete gives you achievements for completing quests and uploading traces. They are automated but it makes it look like actual people are grateful. Of course most people who use OSM will never actually thank the contributors but you’re still doing a great service by improving the map around you.




  • Well, the following PM Petr Fiala, much like Biden, inherited a COVID-wrecked economy and did a great recovery. Still, the recession became associated with him and we are still expecting ANO to be the strongest party and Fiala’s fragile multicolor coalition may break apart… He is both pro-Ukraine and pro-Israel - the former is in agreement to the general population, while people are mostly indifferent for the latter (all Czech administrations have been quite pro-Israel though, supporting trade and speaking for it internationally). Babiš voters are not entirely pro-Russia (that would be half-Japanese Tomio Okamura’s nationalistic SPD party - no relation to the German SPD) but they are condemning Fiala’s unwavering support while Trump “did the bold move and asked for minerals in an art of the deal”. Babiš is really like Trump but more competent - he bought media empires and doesn’t change his plans on a whim. Still, his views are idiotic: he proposed to end licence-based funding for our public TV “because many TV owners may prefer other channels and this is taxing them too”, suggesting it could be funded from the country’s budget (which would make non-TV-owners pay too). It’s stupid but it’s a calculated move: his voter base watches TV but mostly non-public.






  • StreetComplete quests be like:

    • What kind of building is this?
    • How does this path cross the barrier here?
    • Is this path completed?
    • Is it lit here?
    • Do you need to pay to enter here?
    • What’s being grown here?
    • Are there showers here?
    • What religion is practiced at this place?
    • How many steps are here?
    • Which direction leads upwards for these steps?
    • Any vegetarian items on the menu here?
    • What’s the name of this place?
    • On which level number is this place located?
    • Is this a one-way street?
    • Does this road have a shoulder or breakdown lane?
      • I wish I had a shoulder to cry on during my breakdowns :(
    • Do these traffic lights have a tactile indication for blind people for when it’s safe to cross?
    • How bumpy is the road here?
    • Which destination is signposted for this highway?





  • I simplified it a bit. Reddit blocks embeds with CORS or something (and I think Imgur at some point did too) so you do need a deal.

    For YouTube, you need to get a special embed URL, like https://youtube.com/embed/videoIDhere (or with the domain youtube-nocookie.com if you’re cool). That’s easy to generate but if your site includes embedded YouTube videos it also means visitors agree to their ToS, and Lemmy devs don’t want that. Believing in net neutrality, they would need to enable ALL iframe embeds from ALL websites, which could easily get messy with tracking and whatnot. As for Imgur, the default (and the most frequent) way people get an image URL is the album URL even for single images. You’d need to contact Imgur to query the number of images and their URLs to enable the kind of embeds you’re looking for. AFAIK, Reddit does that but it probably costs them money for an API key.


  • Video posts totally work on Lemmy. However, the video must be on the “free and open internet”. Allow me to explain.

    Lemmy, like Reddit, only allows for text posts and link posts. You can make “media posts” because most instances will allow media upload via a pict-rs server running on a subdomain, seamlessly creating a link post when you do.

    However, this only applies to media you can obtain a direct link to. Other than instance-specific* pict-rs, the only major public sites that allow direct URL hosting are Catbox and GitHub. We don’t have deals with major video hosting sites like YouTube, TikTok, v.redd.it, imgur etc. to embed videos when someone posts a link to the website the video is hosted on. Therefore, any link posts will have to be opened as an external website, which is very annoying indeed, especially for the aforementioned JS-heavy sites (unless the other user has an alternative frontend app such as Piped or NewPipe set up).

    * Instance shenanigans: Some instances impose a very small size limit to uploads or only allow them a certain time after account creation (both for lemm.ee for instance). You won’t usually see admins sharing what restrictions they put in place, but we can get a good guess from the defaults (error 502 currently, see archive). These defaults remain unchanged by many instance admins and the TL;DR is:

    Applies to any media

    • 10 MiB limit

    Static pictures

    • 10000x10000 or 40 MP
    • all major formats (webp, jpg, png, jxl)

    Animated pictures (colloquially known as gifs)

    • 1920x1920 or 2.08 MP (basically 1920x1080 in either orientation)
    • all major formats (webp (recommended), apng, gif, avif)

    Videos

    • 3840x3840 or 8.3 MP (basically 3840x2160 in either orientation)
    • 900 frames (that’s like 30-40 seconds but you can get longer with something like a VFR slideshow)
    • no sound, I think
    • all major formats supported but unless it’s VP9 in a WebM container, it will be transcoded by the server and the timeout of the ffmpeg operation is like 15 seconds! This means that it’s practically impossible to upload any but the shortest videos unless they’re VP9 in WebM already!

    You can see that video upload is very limiting! If you’re tech-savvy you can get a lot out of the 10 MiB and 900 frames but you need some ffmpeg skills. Therefore, your best bet is uploading to catbox.moe or GitHub (via a repo and using https://raw.githubusercontent.com/yourUsername/repoName/branchSuchAsMain/imagePath.png or the issue loophole (max 25 MiB)), obtaining a direct link to the file and pasting it as a link post URL. Or just paste the YouTube, TikTok, v.redd.it, imgur etc. URL and deal with the fact people will have to open the heavy website (or their alt-frontend app like NewPipe).
