So, you are on your mac, you right click on a file and search for "compress with password".
Tough luck, there is no such thing out of the box.

But fear no more! There is a simple way to do this, via terminal! Come on, do not be scared. It is not that difficult.
All you have to do is open terminal and:

I was installing something today and I got an error. Looking closer I found there is a warning in the output:

Apple Watch Series 7 of 9: After 19 months and worth upgrading to 9?

Apple Watch Series 9 has just been released and I do not have it! However, I have it's specs and was not that difficult to compare it with Series 7, the one that I currently own and use for more than 19 months. And I have a lot to say about it. And the most important: I have to say something about upgrading from 7 to 9.

CarPlay and USB-C are best friends! You just have to know which cable to use. So, do not be scared, watch this and learn something. I am using an iPhone 15 Pro with seven cables:
1. An ordinary USB-A to USB-C (Type C) cable - no data support
2. IKEA LILLHULT USB-A to USB-C (Type C) cable
3. Baseus CATYS-02 USB-A to USB-C (Type C), 1m, 66W
4. Belkin Boost Charge Flex USB-A to USB-C (Type C), 1m
5. Tellur Led Glowing Connection USB-A to USB-C (Type C), 1,2m
6. and 7. Two high speed USB-A to USB-C (Type C) cables from NVMe enclosures.

Hello world,

I have encountered today at work a situation where I had to know which established connections are using TCP keepalive and which are not.
If you do not know what TCP keepalive is, check out this link. It explains EVERYTHING! :)

In this episode I am presenting the dash camera Viofo A139 Quad HD which means 2K.
Using it few month already I can say it is quite good, with quality recordings (back and front) and reliable.
Mixed with a wireless remote and hardwire kit, you can do more like:
- lock a video without the need to reach the camera
- have the camera stop/start with the engine
- parking mode

I have upgraded to Ventura and while the modifications are not bad, Apple managed to wreck something that was working very well on previous macOS versions and also on countless linux servers around the world. Yes, I am talking about Samba.

I had an issue a couple of days ago in which I had the /docker filesystem full and unable to pinpoint exactly which docker container is using it.
Fortunately docker comes with powerful utilities to help you out with this.
Follow what comes if curious.

How to check how docker is using the system space:

The following commands even if they are close they provide different output. the -v option will give you way more details
docker system df -v
docker system df

The following pool is normal, not mirror, on one disk

18:02:00 root@eeny:~# zpool status
  pool: tm
 state: ONLINE
  scan: resilvered 3.11T in 16:27:30 with 0 errors on Fri Apr  1 13:07:34 2022
config:

	NAME        STATE     READ WRITE CKSUM
	tm          ONLINE       0     0     0
	  sdb1      ONLINE       0     0     0

I have another disk, same size and I would like to convert this pool into a mirror one

Fount this problem today and must share it with you.

01:09:18 root@eeny:~# zpool import tm
cannot import 'whatever': no such pool available

Oops, got scared a bit :)
You should not because what follows may help you.
That is assuming the disk with that pool is attached, available and not damaged :D
