terminal – suppression of zsh-verbose messages in macOS Catalina

I know that Catalina uses zsh as the default login shell and interactive shell. However, it is very annoying when I open iTerm.app or start a command /bin/bashIt shows a detailed message as below

$ /bin/bash
The default interactive shell is now zsh.
To update your account to use zsh, please run `chsh -s /bin/zsh`.

Privacy – Delete Facebook Messenger messages for all users?

I'm trying to restore my privacy by deleting some social media apps. I start with Facebook and Messenger because I use them the least, but I see that disabling or deleting your Facebook account does not delete your messenger messages for other users: the record remains intact. I want to delete my presence completely, so I read these answers here and here. I have a few questions:

  • Do these methods still work? These answers were given in 2015, 2016 and 2018. Are they still valid now?
  • Do I have to deactivate and reactivate my account, or can I just mark all my conversations as spam and then permanently delete my account? Is reactivation necessary for this method to work?
  • Finally, do I tag the entire conversation thread as spam or just my messages? Anyway, how does that work?

Thanks in advance for helping me regain control of my privacy.

webapp rec – script to remove multiple messages Linkedin

Unfortunately, I have so many messages in Linkedin that I need to delete them all in several ways, but Linkedin allows one after the other.

I was looking for a way on the internet, but all fail with me in MacOS Google Chrome.

Unfortunately, all failed !!!

Can someone please edit or provide suggestive code!

I'm sorry I do not understand much in these things, but I do a lot of Mathematica and a little Java.

Submitting web forms does not cover all fields in e-mail messages

We have a web form with two sections. The first section requests information about the user submitting the form. The second section requests information about what the user is looking for.

We've set up email processing so we'll get a message when a user completes and submits the form. Our problem is that the e-mail sent to the specified e-mail address contains only the fields that are in the second part of the submission. In other words, we only get information about what the user is looking for. The e-mail does not contain the user name, location, e-mail address or any of the other fields from the first section of the web form.

The custom subject "Webform submission of: [your_name]" also does not work, which we think is a related issue. The data from the field "your_name" is not included. The e-mail contains in the subject line only "Webform transmission from:".

Both records are stored in the database so that the data is complete there. However, only one part, the second section, is transmitted in the e-mail.

We wonder if there is an environment that we overlooked? Or can not the web form transfer all the fields of a web form with multiple sections?

We are Drupal 8.8.x-dev and Webform version 8.x-5.x-dev

WhatsApp: Secure continuous loop of messages and do not enter a text box in Samsung S10


Two Issues I Face in WhatsApp in Samsung S10 (Fully Updated)

1- Whenever I open the WhatsApp settings, a message "Save your messages" will appear once it's done, and I'll try to go back to the chats and start three or four times, then I can go back. (Backup Settings: Never and unable to associate it with a Google Account)

2- In each chat, the text box below is hidden and I can not type anything. The only way out is to answer someone, hold the phone level, and then type and send.

That's really disappointing, especially that I've just switched from iOS to the new Samsung S10 to find these issues!

(Note: I used a WazzapMigrator to get all my WhatsApp data from my iPhone.)

How are calls or text messages used to exploit a smartphone?

How can I use a phone number to access a smartphone? I read claims that you receive a phone call or text message on your phone and an attacker can install their malware in this way. Are such methods possible? That seems a bit over the top. What methods are used to accurately install malware on a smartphone? I have a fairly basic understanding of information security, books or reading sites are welcome.

Linux – Sophos UTM 9 OSPF HI messages are not multicast

I am trying to enable OSPF on a Sophos UTM 9 on a LAN interface on which two other routers successfully run OSPF.

My configuration is as follows.

Interfaces and Routing -> Dynamic Routing (OSPF)

  • Area
    • Name: normal
    • Domain ID:
    • Surface type: Normal
    • Auth Type: Off
    • Connection via interface: LAN1
  • interfaces
    • Name: LAN1
    • Interface: LAN1
    • Auth Type: Off
    • Cost: 0
    • Advanced
      • Hello interval: 10
      • Retransmission interval: 5
      • Dead time: 40
      • Priority: 1
      • Transmission delay: 1
    • Advanced
      • Redistribute connected <- Enabled
      • Metric: 10
    • Global
      • OSPF status: switched on (ie green)
      • Router ID: (ie the IP address on the LAN1 interface)

The firewall configuration looks like this to allow OSPF multicast messages:

Network protection -> Firewall

  • LAN1 —– (OSPF) —–> Multicast
  • Multicast —– (OSPF) —–> LAN1

Here, OSPF is defined as a service definition with the following characteristics:

  • Name: OSPF
  • Type of definition: IP
  • Protocol number: 89

Multicast is defined here as a network definition with the following characteristics:

  • Interface: Any

When I log in to Sophos UTM 9 as root and run tcpdump on the LAN1 interface, OSPFv2 hello messages are sent from the directly connected router to the multicast address, but Sophos UTM 9 does not send any OSPF "hello" messages ,

One thing struck me … It seems that enabling OSPF on the interface in question does not subscribe to this interface for the relevant OSPF multicast groups: and

This should not affect outgoing Multicast OSPF messages (here, as already mentioned, I see the problem).

To the incoming Messages, as stated above, tcpdump shows that they hit the network card, but I doubt they will forward the TCP / IP stack due to the lack of a subscription.

my-utm:/root # ip maddr show eth0
2: eth0
link 33:33:00:00:00:01
link 33:33:00:00:00:02 users 2
link 01:00:5e:00:00:01
inet6 ff05::2
inet6 ff01::2
inet6 ff02::2
inet6 ff02::1
inet6 ff01::1

Can someone see from the configuration and observations described above what I am doing wrong?

Thank you in advance.

Command Line – Why are some messages included in a back tick and a single quote?

I have often observed that some messages in the terminal or part of them are contained in a back tick and a single quote. For example, the output of type -a ls to generate

ls is aliased to `ls --color=auto'

I expect backticks and quotes to work in pairs, but here's 1 back tick at the beginning and 1 single quote at the end.

Why is there no closing back tick or no starting quote? Is it a standard?
