Any interesting trends from Covid-19

Germany stopped flights now from/to UK as well

Good news, at least some governments can make sensible decisions.

I am surprised about the speed, Germany made a decision. Normally we are not that fast.

Somebody needs to react quickly in these situations, good for Germany and all the others in this case.

I agree, the fact that the new tiers were announced yesterday evening to come in at midnight and then half of London tried to escape last night just shows how bloody stupid people are. These are the idiots who will be spreading it and making it worse. Should just have gone straight into lockdown.

Mainly selfish, in my opinion, rather than stupid.

Pretty busy for a saturday morning, especially as a christmas day.

Traffic in central Florida seems to be down to 75% of normal for this time of day (08:40 local) on a Saturday. I suspect that traffic will pick up substantially tomorrow with travelers returning home.

Traffic was very quiet the last days after December 23rd.

But today business starting to come back again.
The reported aircraft at 01:00pm was the same amount as yesterday the whole day.

Haven’t had that traffic since two weeks:

Total Aircraft as seen by my feeder, near KCAK, Northeast Ohio,USA. 2020-01-01 to 2021-01-01.

That is mine, look similar

Normal traffic here in Toronto
Can you guess which version of dump1090 I am using? :wink:

The one you compiled on a smart refrigerator? :smiley:

:rofl: :rofl: :rofl:

No, compiled on RPi Model 4 / Raspbian Buster.
It is mother of all versions of dump1090
Thanks to Salvatore Sanfilippo GitHub - antirez/dump1090: Dump1090 is a simple Mode S decoder for RTLSDR devices

 

sudo apt install git librtlsdr-dev pkg-config

git clone https://github.com/antirez/dump1090  
cd dump1090  
make  

## During first attempt of `make` encountered error
## dump1090.c:472: undefined reference to `rtlsdr_read_async'
## dump1090.c:2640: undefined reference to `rtlsdr_close'
## collect2: error: ld returned 1 exit status

## Fixed it as follows
## Give following command to find location of file `librtlsdr.pc`
pkg-config --libs librtlsdr --debug

## Edited file `librtlsdr.pc`
sudo nano /usr/lib/arm-linux-gnueabihf/pkgconfig/librtlsdr.pc 

## Four lines at top of above file modified as below:

prefix=/usr
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include
## After fixing the bug, `make` was successful
cd dump1090  
make  

ls
anet.c  anet.o    dump1090.c  gmap.html  README.md  TODO
anet.h  dump1090  dump1090.o  Makefile   testfiles  tools

sudo reboot

 

./dump1090 --net --interactive

–net required to see map at:
IP-of-PI:8080

It must be quite satisfying to write a piece of software and see it so widely adopted.

Yes, you are right.

The antirez version I compiled today, has the openstreet map, and planes are the shape of real planes. I remember that when I compiled it some years ago, the map was google map and planes were like the paper planes we used to make in our school days :slight_smile: .

Here is an old map I found on internet.

YARF? - Yet Another Random Fork :wink:

It is the original and the very first dump1090 ever written.

The forking took place like this:
dump1090 (antirez) >> dump1090 (Malcolm Robb) >> dump1090-mutability >> dump1090-fa

There are various other “not so popular” forks, some forked from original antirez dump1090, some from MalcolmRob’s fork, and some from mutability fork

Compile one of the “not so popular” forks (my readsb) and see if you can notice a few demodulator tweaks compared to dump1090-fa :wink:

Should be getting a couple more positions (it’s not huge but it’s a difference).
