#ios #tip If you travel and have multiple eSims - ios takes the first letter as abbrev. for the cellular indicator (hence I thought my main line had “P” for primary while it was for the operator Proximus all along). This first letter can be set and can be an emoji.

some weeks ago I found a very cool tui tool to sniff packets while working on a usb device: tshark

it is included with wireshark, and really I don't know why I didn't notice this tool before

for me it's very clean, and it's just a matter of correctly setting the filters to get what I want

for example, the following command will listen for the device 21 attached to the bus 3 (lsusb will show you needed info), getting IN and OUT data:

```
tshark -i usbmon3 -Y "usb.device_address == 21 && !(usb.urb_type == URB_SUBMIT && usb.endpoint_address.direction == IN) && !(usb.urb_type == URB_COMPLETE && usb.endpoint_address.direction == OUT)" -Tfields -e usb.endpoint_address -e usb.capdata
```

you will need to be sure that the usbmon module is loaded on your system, and that you are a member of the usbmon group

the attached image shows some of the captured data

¿Qué es zram?

Es un sistema que hace las mismas funciones que #swap, pero en vez de paginar en disco lo hace en una parte de la memoria en modo comprimido. Se consigue un mejor rendimiento a cambio de hacer un mayor uso de la memoria.

Dependiendo la distro, por ejemplo, #Debian, necesitarás instalarlo con el siguiente comando: 

sudo apt install zram-tools

y luego activarlo

sudo [editor] /etc/default/zramswap

Descomenta "PERCENT=50"

Reinicia servicio:
sudo systemctl restart zramswap.service

Para verificar:
zramctl
free -h

Quarterly reminder to check yourself to have sleep apnea if you think you sleep too much.

I weighed 60kg, was totally healthy and still slept 18-20 hours each day but felt like 10 minutes. It's a life-debilitating condition that worsens gradually and you may not notice. (I was getting so little REM that I had hallucinations almost daily)

Getting checked for sleep apnea after about a year of my partner telling me to was one of the greatest things I ever did, and I'm still amazed with how long days are now.

Please, PLEASE, if you record yourself sleeping and notice pauses in your breathing, get yourself checked. You'll greatly thank yourself and you may even double or triple your time awake!
