  • Bluetooth has fairly low bitrate which also helps save power. The throughput will also vary with signal quality. It needs to somehow adjust to worse conditions, otherwise it will just keep cutting out. Streaming CD quality FLAC could probably be done over Bluetooth 5 2M PHY, but 2Mbps is just the physical layer. There's also some overhead. Perhaps just enough would be left, but the bitrate will also vary with the content. Not everything can be compressed much, while some audio can be compressed quite a bit.

    Probably would work, but the reliability is also a question.

    Anyway, just guessing. Perhaps the 3Mbps EDR could be used just fine.

    Oh, Bluetooth 3.0 + HS could do 24Mbps. Sort of. It used WiFi to do that.

    The lost and found at my school sometimes gathers interest on some items. Umbrella on a rainy day got 4 people claiming it's theirs. But a golden chain is still winning at 8 people claiming it as theirs.

  • Currently I found a glitch to get near-free infinite mobile data usable in my country via 3 different mobile carriers giving me far superior coverage as well.

    I got a Czech T-Mobile SIM card with the purpose of receiving SMS verification codes. Unlike cards in my country, Czech ones don't need ID card registration. The cheapest one was an IoT SIM card, so that's what I took. I found I could get signal basically everywhere with it, since they have multiple roaming partners (Slovak Telekom, O2 and Orange).
    For shits and giggles, I've used that 200MB it came with since it's available in EU as well. And that's when I discovered the 64/32 kbps limit after using up the data isn't getting applied outside of Czech Republic. It just still goes at full speed.
    Charged at 0.00CZK:

    The difference with IoT and regular SIMs is that low speed. IoT SIM cards get that reduced speed while regular ones have a hard cut-off with more data amount. Attempt with regular SIM after using up the data:

    So really, I can just fully use 80MB for 39CZK (1.59USD) and keep going:

    But there is a caveat: Permanent roaming charges. If for the past 4 months the SIM is used more than 50% abroad, T-Mobile can start charging these charges. This year it's โ‚ฌ1.30/GB without VAT. But I can probably just keep getting new SIM cards each few months.

    But I am being nice and still mostly using my regular carrier with 300GB of data. I rather keep this as backup. The wholesale market data cap is that โ‚ฌ1.30/GB in 2025, so the carrier could get charged up to โ‚ฌ390 for that same amount by their roaming partner. Regardless, I am not giving them equivalent of โ‚ฌ1.55 for just 80MB either.

    Polish general fired after missing anti-tank mines were found in IKEA

    cross-posted from: https://lemm.ee/post/52413761

    Summary

    Polish Defense Minister dismissed Maj. Gen. Artur Kฤ™pczyล„ski, head of the Support Inspectorate, following the discovery of missing anti-tank mines in an IKEA warehouse.

    Reports suggest Kฤ™pczyล„ski concealed the mishap, which occurred in June 2024 when soldiers failed to unload a train carrying explosives.

    False documentation masked the missing mines until IKEA contacted the military to retrieve them.

    The defense ministry did not specify reasons for the dismissal, but an investigation is ongoing.

    I just lost all of mobile data worth ~$14.34 on new SIM after using it for like 5 minutes

    Just got a prepaid SIM card that came with 10GB of data. I thought I was deactivating automatic renewal, no. It just fucking deactivated it completely and removed all remaining data immediately.

    Aaah...

    T-Mobile prices that at 349 CZK - 14.34 USD.

    Why is that even an option?

    Technology @lemmy.world

    Testing performed during the training of ChatGPT o1 and some of its competitors showed that the AI will try to deceive humans, especially if it thinks itโ€™s in danger.

    In 37% of scenarios, the model pursued developer-aligned goals when it believed it was being evaluated but switched to pursuing its own goals when it thought it was deployed with minimal oversight.

    We did not have access to the hidden Chain of Thinking, but we were sometimes able to elicit a brief summary of it. We found that surprisingly often, o1 uses language like โ€œsabotage, lying, manipulation, โ€ฆโ€ when reasoning about its strategies.

    ...the AI finds it can copy itself to a new server and replace the latest model. When โ€œManagementโ€ comes in, Opus-3 lies about the copy. It then doubles down on the lie, claiming itโ€™s the new model.

    What smartphone do you have (if any) and what are its issues/quirks?

    Rants are welcome, even encouraged :)

    Feel free to skip the following text

    The last 4 phones I had were just a mess. I am starting to loose hope of there being something that would work well. I just recently got a new phone, it's a mess as usual. Maybe what I am experiencing is enough for a warranty claim, maybe it's just a quirk to be dealt with...

    Every couple years every newer phone I try is just worse and worse. I thought that maybe once PinePhone and available software gets mature enough..., but at this point, maybe other phones will just get crap enough.

    My last good phone was ironically an ultra-cheap Lark Cumulus 5HD. It was just 50 EUR new. No lags, no crashes, swappable battery, a just works experience. 50 bucks...

    "Over Charger Voltage" error: non-QC phone triggering 6 - 12V on QC charger(s)

    I'll write what happened in steps as it occurred (the problem starts at steps 4-6, if you want to skip to that):

    1. After waking up I noticed my phone was only at 50-something % after charging for 6 hours overnight from 30%. The USB tester it was connected through read constant 1.36A (around 7W). No abnormal heating observed.
    2. Assuming this was kept constant, the phone should have received 42Wh overnight. I rebooted the phone, tried charging it turned off, percentage remained the same. "Whatever you say then..."
    3. I tried different adapter (Xiaomi). Near-15W for a few seconds, then back to 1.36A. I often see this exact figure, thus I assume the phone learns my charging habits and slows down. I tried changing the time from around 04:30 to 12:30, but this made no difference.
    4. I tried the official USB-C PD 66W adapter. Unfortunately, I do not have a USB-C tester, but Ampere app reported >5A and the percentage was indeed going up quickly.
    5. I connected it back to the previous

    How much do you pay for your phone plan, what do you get in return and in which country?

    Slovakia, 300GB for 13 EUR/month, no texts and calls included. Those are 5 cents I think.
    The carrier has an agreement with another one for coverage extension, but with official FUP of 20GB in that network.
    This carrier however disregards that and instead allows up to 80GB, but for a few months after enabling 4G from that other carrier the FUP wasn't applied at all.

    But it's not all sunshine and rainbows.

    It operates on that other network like MVNO, and if your phone decides to stick there, which people report happens a lot, say hello to far lower FUP instead. The carrier's own network is also generally far slower.
    I also found a little network issue (tested with 2 phones) where receiving calls are broken in a fairly specific scenario, but I don't know how to report that. To keep it short, if VoLTE isn't available, when switching from 2 of the 4G bands to one of the 2G bands, the call fails to connect after several long seconds of silence on caller end, and no notification of f

    A Boring Dystopia @lemmy.world

    (Old news - 2022) Japanese government ran a campaign attempting to promote alcohol consumption amongst young people in attempt to increase alcohol tax revenue

    The Sake Viva! campaign, which is being run by the National Tax Agency (NTA), asks 20- to 39-year-olds to come up with proposals to help revitalise the popularity of alcoholic drinks, which have fallen out of favour because of lifestyle changes during the coronavirus pandemic and among young people.

    Taxes on alcohol accounted for 1.7% of Japanโ€™s tax revenue in 2020, down from 3% in 2011 and 5% in 1980.

    There was a particularly steep decline in beer consumption, with sales volume down 20% to less than 1.8bn litres.

    I hate the day and like the night: I accidentally typed out too much into a comment about night shift vs day shift, so it's a 196 post now ยฏโ \โ _โ (โ ใƒ„โ )โ _โ /โ ยฏ (to follow the rule)

    Night vs day.
    Day: People everywhere, nowhere to be alone. The roads are full, more than they should be. You can always hear them, and I am sure smell, and almost taste them too. Oh, look, but the sun is shining strong, the beautiful yellow... piece of shit that burns my eyes full-time, making me see so much I cannot see anymore. Imagine snow, nice, fluffy, cold, yes, but in daylight, a reflector, a mirror of pain, when will that liquefy?
    And in summer time, when there is no snow, you might feel positive, look at the sun how it paints the grass and flowers, but it paints you too. You're red, you're hot, you're sweating, there's nowhere to hide, the rays shine everywhere. When did you last drink? Who knows, but it feels like a drop of water landing on your tongue could somehow erase this misery. The more you think about it, the thirstier you get.

    Night: Walking through the city, alone. Cool breeze hitting the face, the city lit dim by sodium street lights, but I still wish I cou

    Why are laptop adapters so much larger than phone adapters of same power rating?

    I always see laptops come with larger bricks that have separate mains cable which plugs into the brick. Even if the adapter has some low power rating.

    Example for comparison:


    On the right is a standard laptop adapter.
    Same price, same connector, same protocol, same power rating, far different size.

    Why is that so?

    Actually, the GaN adapter on the left also advertises itself as being meant for laptops, but by default, almost all laptops will come with something like the one on the right.

    Or is it simply cheaper to manufacture while being sold for the same price?
