abc music notation is, well, music notation intended for print. It is easy to understand. It is not that easy to convert into midi.

What are good resources for determining position without gps (from cellid / wifi APs)? Should I be looking at anything besides https://beacondb.net/ ?

@beacondb Hello... and thanks for your work. I'm currently playing with geolocation, and am wondering:

a) is there cell tower dump available somewhere? That should not have many privacy problems. I have last dump from Mozilla project, but that's old and... has a lot of non-existing LACs and cells outside of country

b) is there well-known wifi AP I could use for testing? Coverage is not good in my area, and two mac addresses I could enter and get well-known coordinates back would be cool. Dunno, white house would be nice for testing :-).

Vratime se z vyjizdky, a nabizim mu kybl. Napije se presne jenom tolik, kolik je nutne, aby dostal kus chleba. Zjevne nema zajem. Fajn. Jdem do vybehu, kde ma tu spravnou vodu, jenze ouha, ona tam neni. Tak jo, zpet do staje, a najednou... ma zajem.

Chvili pasem, a na slunicku je prijemne. Rikam si, ze uz by to pro dnesek mohlo stacit, zvednu hlavu a koukam... jo, zlutej mi jde naproti a lehce porechtava. Jde ke me, ne k vychodu, a jde v klidu... coz je super. Tak jo, mohutne chvalim, jdu pro druhyho kone (a ano, ted uz si na me i zarve), a vicemene v klidu odchazime. Jupi!

Prejem Madarsku hodne stesti... a vlastne zbytku Evropy take.

I would like test data for wifi geolocation: bssids, lat, lon. Something without privacy problems, university campus, railway station, ...?

Prijdu k vybehu a zavolam na konika. Koukam, a on zjevne spi ve stoje. Ale behem par sekund se probudi, promysli si, co po nem asi chci, protahne se jak kocka, a vyrazi k vychodu. Sikovnej konik!

Tady zacalo snezit. Jeste pouvazuju, jestli dneska pojedu za konem na kole...

LACs are important. When your phone crosses a LAC boundary (an area), it reports to the operator so they know roughly where to find it. On GSM, you can even hear it if the phone is near a speaker. The communication happens with a cell tower — and there are quite a few in the area (dozens) — so you can be fairly sure the operator keeps records, and kind of “forever.” What’s worse, the network is built on something called SS7, and your security wasn’t really a priority there. So effectively, any operator could probably track you fairly cheaply. And when I say any operator, I mean basically anyone who can make a deal with an operator.

Areas are also important for battery consumption. If the operator has misconfigured the network, or if you’re unlucky and your living room ends up in a different area than your kitchen, you’ll notice it in battery use.

Yeah, if someone really wanted to spy on you and was willing to invest more than a few pennies, they have lots of ways to figure out which cell you’re in. Silent SMS, for example.

You can view network information using an app like SatStat. So, do you know which LAC you live in?

-------------------------

LACy jsou dulezite. Kdyz se Vas telefon presune pres hranici LACu (oblast), tak se ozve operatorovi, aby vedel, kde ho ma hledat. Na GSM je to hezky slyset, kdyz je telefon pobliz reproduktoru. Komunikace probiha s nejakou bunkou, tech je v oblasti docela hodne (desitky), a muzete si byt celkem jisti, ze si operator vede zaznamy a to tak nejak na veky. Co je horsi, sit je postavena na cemsi jmenem SS7, a na (Vasi) bezpecnost se tam prilis nemyslelo. Takze efektivne vas nejspis muze sledovat libovolny operator a to velmi levne. A kdyz rikam libovolny operator, no, myslim tim v zasade kazdy kdo se s nejakym operatorem dohodne.

Oblasti jsou dulezite i pro spotrebu. Pokud bude mit operator spatne nakonfigurovanou sit, nebo budete mit treba smulu a obyvak spadne do jine oblasti nez kuchyne, poznate to na spotrebe.

Jo, kdyz Vas nekdo bude chtit opravdu spehovat, a bude ochoten investovat vic nez nejake halere, ma spoustu moznosti jak zjistit, ve ktere jste bunce. Tiche SMS, napriklad.

Zobrazit informace o siti muzete treba pomoci aplikace SatStat. Tak co, uz vite, v kterem bydlite LACu?

Mila mBank.cz, nebylo by dobre udelat placeni na internetu jeste otravnejsi? Jasne, opisuju cislo karty, CCV, a 6-ti mistny kod. To by se +/- dalo pochopit. Ale proc mam opisovat nesmyslny text ktery mi serviruje Vase nedomyslena brana? Nejaky cosi cosi vrabec brsfkof? Urcite sezenete nekoho, kdo Vam vysvetli, jak udelat mene otravne zabezpeceny web.

Or is that just artefact of MLS-full-cell-export-final.csv.gz? There's more strangeness in there...

GSM cell towers are grouped into LAC areas. And... it seems those LAC numbers in Czechia have patterns in them -- way too many are divisible by 100 -- and they are actually consistent across 3 major operators. LAC 28752 is around Třinec, for example, in all three.

If someone knows more, tell me, there may be more patterns I missed.

Septa vas kun?

Kone vydavaj ruzny zvuky. Tesi me, ze je +/- systematickej prehled, treba na https://www.youtube.com/watch?v=18z1sAps6Gc .

A zlutej vydava cim dal vic zvuku. Zacal septat. A vlastne ... hodne koni okolo me zacalo septat. Ja dam bridge, a oni zabublaj. Zlutej to nedela tak casto, ale dneska byl hladovej, a viditelne chtel pracovat. Jenze ja chtel v tu chvili pohladit jinyho kone, a zlutej byl celkem nestastnej. Postavil se vedle me, do polohy jako kdyz se vede, hlava rovne, a zabublal, ale tak tise ze stat o krok dal neslysim nic. Pekne. No, jeste par sekund pauza, a te prace se dockal.

Did RedHat turn to spamming now? Noreply address, intentionally confusing body, no clear way to unsubscribe, no information why I'm getting this in the first place. Illegal according to czech law. Come on, solid companies do not behave like this.

How do you program for Android? Lets say "display me a distance to given gps coordinates"? Long time ago, there was sl4a, allowing you to run python scripts; it could do simple dialogs, but not real UI. I am aware of Termux. Is there something else? There's MicroPythonOS.com that can do gui on esp32 and linux with few lines on code (LVGL based UI), is there something similar? I could write javascript and run that in a browser, but...

Jedem... vzhledem k rocnimu obdobi docela daleko. Zlutakovi ani kobyle se 2x nechce, zlutej to rika celkem slusne, kobyla to rika o neco min slusne. Tak ve tretine nejak pochopi, ze stejne pojedem, a kolem poloviny zacnou i celkem slapat. A potom... no, oznami nam, ze tady se pred pul rokem pasli, a ze uplatnuji pravo past se tu znovu. Aha, takze jedem jeste par metru, a pak se uplne nezavisle rozhodujem, ze tady je dobry cas na svacinu, a ze kone si teda muzou kousnout.
