On: In Argentina, inflation is a way of life

[emi420]

When a company sends USD to a bank account in Argentina, the bank must to convert that amount to "pesos argentinos" (ARS), using the "official rate". You can't get USD transferred to your account from other people than yourself (or a company owned by you).

Right now the "official rate" is 110,5 ARS for each USD, but if you sell your USD (using crypto or in the "dark market") and get ARS, you'll get 222,5 ARS for each USD.

And that's before the taxes.

And you can't bought more than 200 USD per month at the official rate, so the need to bought the USD through an exchange or in a "cueva".

It looks very similar to this other piece of art:

What about the sharpening of that tool? seems to be inverse than on a Pulaski, it works good anyway?

[gdubs → emi420]

Great question! I haven’t sharpened it yet, but it’s made from reclaimed agricultural discs which are known to take a beating.

1996 in Argentina, Coke did a promotion where promised "two caps for a Ramones concert ticket" (we are huge fans here). Of course they didn't can keep with this promise and disturbs occurred:

"disturbs occurred"! I love that expression!

I'm working in a project for my local fire station to receive GPS data via VHF radio (widely used by emergency services in my country). We are trying with DTMF, this seems interesting.

There is a lot of prior art here, the most relevant of which is probably APRS: https://en.wikipedia.org/wiki/Automatic_Packet_Reporting_Sys...

Newer digital modes do much better than this older AFSK system, but FSK does work pretty well. Some newer things to look into:

FT8: https://en.wikipedia.org/wiki/WSJT_(amateur_radio_software)

The more interesting modes (WSPR, FT8) are designed for high-loss channels, so have a lot of error correction. For example, I can use 5W of power, indoors, to communicate across the country with it. For high-bandwidth VHF channels, it doesn't matter what you use really. The goal would be to find something that already exists and is easy to integrate, and there are a lot of options.

Don't they already do this? I hear them all the time on my scanner? Hell they use a four digit unencrypted code to activate the emergency sirens.

[copperx → paulie_a]

I thought that fire trucks had a switch to activate the sirens by the drivers; I had no idea they were activated remotely by radio.

[paulie_a → copperx]

I was referring to the standalone towers in the Midwest. Maybe elsewhere. When I was a kid i would wake up on Saturdays at noon due to the siren. My dad also had a police scanner I could hear. One summer I put 1 and 1 together

All you need is a dtmf decoder and a small transmitter to set the off those large sirens on high poles throughout that sprinkle the country in small towns and probably large cities

Im taking this online course, it is very interesting if you have some prior knowledge and experience and you are self-taught like me, because can make sure if you are making things right or wrong, plus learn new things.

All is public, since doesn't have password. I took a pastebin list, a free geolocation API, and I made this to play: http://big-brotha.appspot.com/static/index.html

[phpnode → emi420]

+1 for effort, but this is really very unethical. Literally all those cameras are broadcasting without their owner's permission

[emi420 → phpnode]

Yes, I disabled the application now. But it took me 2 hours to put it online and it was really easy. People must stop the surveillance of all other people, I think.

And what about chaining USB servers?
