@agturcz @licho I'm not an expert either, but I know for sure that bands for cellular networks are heavily regulated and the legal framework under which they are being used and certified is completely different than for ISM bands like Wi-Fi, which are sort of a special case here.

Also, depending on its design details, you may need to certify your whole product separately even if the module it uses is already certified.

@licho The certification is what makes the hardware licensed and it (in principle) involves not letting the device be used in an unlicensed way.

For details you'll have to check the specific laws and regulatory bodies in particular jurisdictions.

@licho IANAL; the viability of "it's illegal, but I'll be fine unless I get caught" approach is something you'll have to consider by yourself 😂

@jacqueline @mntmn When cross-compiling is a pain, an arm64 container with qemu-user takes all that pain away (for the fair price of performance).

@licho These devices usually contain a broadband module (not unlike the ones in Librem 5 or PinePhone) that's already certified.

And yes, under most jurisdictions you're not allowed to transmit at all without a license; the bands that you can use for stuff like Wi-Fi etc. (with some restrictions) are explicitly allowed to be used unlicensed, and the frequencies used in cellular networks aren't included there: https://en.wikipedia.org/wiki/ISM_radio_band

@licho However, if what you're after is experimenting with cellular tech, then why wait? You can do it today. Get a #Librem5 and replace its modem M.2 card with something like uSDR: https://www.crowdsupply.com/wavelet-lab/usdr

@licho While it's possible, LTE isn't easy to do on SDR - you need full duplex and you'll need a coprocessor for it anyway, or your main AP won't ever sleep and will be under constant real-time pressure. Then you'll need to get it certified if you want to actually use it on public networks. I'm afraid you'd end up with something uncannily similar to a closed LTE/4G modem, just slower and hungrier for power 😜

@lritter @zeborah @_nibbles @GyrosGeier Frankly, when it comes to basic smart home things, it's at a point where "time-costly buy-in" was already done by others. It's like building from LEGOs now.

That said, it's taking me two years and counting to lay the cables and connect my already LEGO-built OpenTherm controller to my boiler, so I understand the friction very well 😂

@grzgrz Nic zaskakującego. Matematyka polega na abstrakcji, a arytmetyka to tylko jedno z wielu jej narzędzi do rozwiązywania problemów. Jeśli ktoś nauczył się rozwiązywać konkretny problem tylko w jednym kontekście, to nie ma to jeszcze z matematyką wiele wspólnego, nawet jeśli w środku są liczby - a tak się zresztą często kończy matematyka w szkole, gdzie dzieciaki uczą się algorytmów na pamięć i nikt nie pomaga im ujrzeć, skąd one się w ogóle biorą.

@Geodad478 Partial updates are possible in Debian, but I was updating Arch today. apt is just so much more robust than pacman.

"upgrading electron32" how do I switch to electron64

the actual reason to use a rolling release distro #linux

Many years ago I spent some time playing with running a graphical interface from chrooted Debian userspace on a jailbroken 1st gen Kindle Paperwhite. I posted a video that showed it and called it "Debian on Kindle Paperwhite". Some tech media had then picked it up and reported on Debian running on Kindle.

I'm sorry, it's all my fault. All those people calling Halium devices "real Linux phones" are just my karma coming back 😭 #mobilelinux

@smatyszczak Najpierw chciałeś "dobrą aplikację mobilną", a teraz nagle "na iOS". Zdecyduj się, albo jedno albo drugie 😜

How to speed up your phone for free - tested guide, it works!

1. Enable KASAN and other kinds of instrumentation while debugging your phone's kernel.
2. Notice how it makes things slower, but not slow enough to be unusable.
3. Keep using the phone this way.
4. Get used to it and forget that these things are enabled.
5. Many months later, get back to stock kernel config while doing something unrelated and enjoy your newly unlocked extra performance! 😝
