Fn function keys on a laptop work the other way around

Usually, to extend the functionality, there is a special Fn key on laptop keyboards.
If you hold it and press keys, for example, from F1 to F12, then they will perform completely different functions, change the screen brightness, volume level, put the system into sleep mode, turn off/on the Wi-Fi adapter, etc.

But in my case, everything was the opposite, when I needed the F1-F12 keys, instead of them, functional ones worked, which usually work with the Fn clamped, and to press F4 for example, I had to clamp the Fn key as well.

As it turned out, the BIOS had an option Action Keys Mode (in Lenovo laptops – HotKey Mode), the default value of which was Enable, which resulted in the function keys working without pressing Fn.
To make the F1-F12 keys work as usual, set the value to Disable.

By the way, if your function keys do not work at all, then rather the driver is not installed in the system.

How to configure SPF records

SPF (Sender Policy Framework) allows you to specify in the TXT DNS records domain settings addresses from which you can send mail to prevent e-mail spoofing.

Here is an example of adding SPF records:

v=spf1 +a +mx -all
v=spf1 ip4: ip4: +a +mx -all

Where, v=spf1 is the SPF version,
ip4:ADDRESS The IP address from which you can send mail,
+a allows receiving mail from addresses that are specified in A-records of the domain,
+mx allows mail reception if the address is specified by the MX record of the domain,
-all reject all other messages that failed verification.

Facebook blocks users after registration

Once used the social network Facebook, deleted the account and a year later, maybe a little more, decided to re-register.
It was around December 2017.
After the registration, I added one photo, Facebook offered to add friends. In the list of suggested friends, I added a couple of friends, and on several unknown people I clicked a cross, hoping that they would not be offered Facebook, I began to correspond with friends, and after a while the message was displayed that the account was deactivated and you need to attach one more photo.
I attached the photo, in the course of the day the account was activated, but after a while it was deactivated again, added the same photo – activated, I was asked for a photo of the passport for the third time, added – activated, later deactivated again and asked for another simple photo, after that the following message was displayed:

You Can’t Log In Right Now.
When we study your photo, we will contact you. For security reasons, we will now exit Facebook from you.

This message was displayed for about two months from 12.2017 to 02.2018, then it was generally displayed that the account was blocked.
Several times i wrote in technical support that he was blocked by mistake.
With the email that was used when registering the account it was impossible to register again, so I had to wait and on 06/03/2018 it was finally unblocked.

But I was already disappointed by such weak technical support and crooked locking algorithms, so I just deleted the account.

Troubleshooting in Thunderbird “The IMAP server does not support the selected authentication method”

I will share information on this issue that has arisen from me.
I noticed recently on one of the computers that the mail stopped loading in Mozilla Thunderbird and the following message was displayed:

The IMAP server “…” does not support the selected authentication method. Please change the “Authentication Method” in “Account Settings | Server Settings”.

Before that, the mail was successfully downloaded, nothing changed in the Thunderbird configuration and on the mail server.
On a neighboring computer with similar parameters, there was no problem.

As I found out, the problem was in ESET NOD32 Internet Security and after turning off its protection (not a firewall) – the problem disappeared.
It’s amazing that the problem did not appear right away, during mail setup for example.

Since this computer was changing hardware and reinstalling the OS, and also mistakenly installed ESET NOD32 Internet Security, I did not investigate the reason for the blockage, deleted it and installed ESET NOD32 Antivirus, which was always on this computer, with the hope to continue to investigate the problem if it repeats itself, but after that it disappeared and did not appear.
