An external image showing your user-agent and the total "hit count"

    Made a meme one that took 3 minutes to program, 5 minutes to find a good offline GeoIP location source for, 10 minutes to come up with a design for, and half an hour to make sure nothing got logged by the web server.

    An image that tells you where you live based on your GeoIP location

      Thanks for the heads-up.

      Routing my Lemmy mobile app through orbot from now on. Seems to have fixed the issue.

      I wonder why the Baltimore community is so dead, then.

      Joke’s on you. IP geolocation where I am is an unreliable mess and your image got it wrong by about 1000km!

        I’m sure it would be better if I paid MaxMind money, but that’d go a bit far for a stupid meme picture that I’ll probably take down in less than a week.

      Hey. I wanted to do this tomorrow.

      Well I have a new idea which is pretty similar

          I’m plannig to make one of these “dox’d memes” where someone says something controversial and another one answers with the ip address.

            Ah, I see! I was also thinking of maybe using something like Google Earth to make a GIF that zooms into your local area but that was waaaaaaay to computationally expensive to render on the server.

      Woah this is really cool. Though I was way off for me and I’m not on a VPN right now.

      Location is right, but I highly doubt anyone near me is using Lemmy (dictatorship here).

      • Skull giver

        If you live in a dictatorship and this thing can get your location right, you should probably be using some kind of VPN. Wouldn’t want you to run into trouble with the regime!

        Probably has bugs. Probably no security bugs. Feedback is welcome (but I don’t care enough about this to try my hardest).

        require_once('/var/www/html/geoip2.phar');
use GeoIp2\Database\Reader;

$ip = $_SERVER['HTTP_X_REAL_IP'] ?? $_SERVER['REMOTE_ADDR'];

$cityReader = new Reader('/var/local/php/GeoLite2-City.mmdb');
$record = $cityReader->city($ip);

header('Content-Type: image/png');

$image = @imagecreatefrompng('lemmybase.png');

$black = imagecolorallocate($image, 0, 0, 0);

// "Some City, SS, Country Name"
$text = $record->city->name . ', ' . $record->mostSpecificSubdivision->isoCode . ', ' . $record->country->name;

/* $font_path = '/tmp/ComicSand.ttf'; */
$font_path = '/usr/share/fonts/ubuntu/Ubuntu-M.ttf';

// Render text
imagettftext($image, 30, 0, 28, 224, $black, $font_path, chunk_split($text, 22));

// Dump image to web server
imagepng($image);

// Free resources
imagedestroy($image);

        Edit: damn, Lemmy really hates < ? php. Just imagine that’s the first line in the file.

          Damn, PHP is such a sleeper of a language, I always forget how useful it can be.Thanks for sharing!

            PHP is the OG bad-ass for getting shit done. No setup, no compile, no deployment pipelines. Hell, you can create and write the files right there on the server with nothing more than an SSH terminal if you want.

            PHP is underappreciated, especially recent PHP. Null coalescing operators! Actually typed variables that produce an error if you pass the wrong type! It’s superior to Python despite it’s mid-2000s-spaghetti-college-kid-developer reputation.

            Hell, I may get downvoted for this, but I honestly believe PHP’s Doctrine is superior to Java/Kotlin’s Hibernate. Symfony and Spring are almost equally good in terms of functionality, though PHP is quite a lot slower, sadly.

              Genuinely curious, how is it superior to Python in your opinion?

              Edit: Apart from the things you listed 😅

                It can run natively on an Apache server without any frameworks required to render user website markup and serve pages. That’s a pretty awesome advantage.

      I was wondering for a second why my town of all places was posted lmao. Also made me realize I forgot to turn my vpn back on.

    • Altima NEOEnglish

      Hah, not my town, but close. That’s where my ISP is located though.

    • @[email protected]

      This is great, because it located me about a full day’s drive from where I live, so I’m still pretty anonymous :-)

        The image is generated on demand by a PHP script. It’s not a static image file. Every time the web browser sends a GET /poc.png, a new image is generated based on the information your browser or app sends the server.

        It’s actually how a lot of tracking code works. The image data returned may be the same, but the data collection through cookies and maybe even some passive fingerprinting all happen every time you send a request.

      • @[email protected]

        It’s not the image, it’s a normal image. The server does the hard work when you make the request, and then it just builds the image accordingly.

        • SokathHisEyesOpen
          4•2 years ago

          Yeah I saw OPs explanation in the comments. That is fucking cool! And scary! I’ve never needed to generate images with code before, so Ive never even considered something like this before.

      • Skull giver
        1•2 years ago

        Haha it’s just an IP lookup in a free database I’ve downloaded, I did 0% of the hard work. Thanks for the reply anyway!

    • @[email protected]

      I hate this so much. Its super cool but MAN what the hell. I don’t think I’m going to ever turn off my VPN anymore. I’m in a super small town and that image is correct.

      It’s cached somewhere because I can’t get it to update. Maybe time for a new account too. Hmmmm

      • Skull giver
        1•2 years ago

        It’s should only be cached in your browser. Try opening the image in a new tab and hitting Ctrl+Shift+R. Opening it in a porn tab or clearing your browser cache should also work.
