  • If you have a recent phone, websites and PWAs are about as fast as native apps. I’m using a 2014 flagship Sony Xperia Z that came out with Android 4.4 and can barely run Android 13 — it will overheat and sytem UI (thankfully not apps) will restart if rendering stuff for too long. (The difference is staggering: basic old apps like Phyphox and static websites run indefinitely. Modern apps or JS-enabled pages like Voyager or 480p30 video for 10 minutes. Post-modern bloated crap or 720p30 video, 4 minutes. Imgur, new Reddit and 1080p video turn the phone into a hand warmer immediately and the framerate goes from 15 to <1 in 10 seconds, followed by a slew of ANRs and the battery percentage going down every 20th frame rendered. Should I have applied more heatsink compound after replacing the battery? Yes but I’d argue no app with a simple purpose and basic GUI should require 5 W to the CPU while running at half rate.)








  • The remote was lying around and I just pointed it at an ATmega on a small breadboard with this code when nobody was looking. I muted the TV briefly to check that it worked, and took the device home to make a transmit-only ATtiny version inside one of those promotional keychains that have a coin cell, button and LED. I didn’t bother with writing the program the “right” way (sleep mode and pin change interrupt, which would eliminate button contact problems and allow for more complex behavior like more buttons or multiple-press), the ATmega just plays the sequence on powerup.

    The other option is to find the closest possible TV model online (not easy, wall-mounted TVs you can’t see from the back barely have any distinguishing features) and check if the listed remote code works. Or use an IR-enabled smartphone, the various apps cover most TV models.



  • It definitely still works in the Czech Republic and Germany. Our pre-2023 president was an avid user. Public TV stations hand-format their own and syndicated news for 39 columns and pick monthly poetry. Commercial stations just automatically jam syndicated news into the format, sometimes overflowing to another subpage just by 1 word, and host huge amounts of banner and fullscreen ads with meh graphics by Teletext standards, mostly for dodgy phone services like tarot and erotic hotlines. They also host “chat24”, probably the worst message board ever: imagine a public IRC room but $0.50 per message (by SMS) including setting your nickname and color.

  • I found a cool way of ad-blocking back when I watched TV. Probably does not work anymore, and relies on Teletext page 888 (closed captions, the number varies by country) not being updated during ads.

    1. Mute
    2. Switch to another channel and back to clear Teletext cache
    3. Turn on fullscreen Teletext, any page (I like the 89x test patterns)
    4. Type “888” as the page you want to go to
    5. The TV will now wait for 888 to be broadcast, which only happens after ads and trailers
    6. The program is now running with captions. Disable Teletext and unmute if you want sound instead.
