sharepoint online – The user message for the column check is displayed for one millisecond

The column check does not take effect until you try to save a new item or save the changes made to an existing item.

Enter image description here

I run tests with the "This column must contain information" setting, which is set to "Yes" or "No" based on classic and modern experience, and I cannot reproduce this problem in my environment.

Maybe you can switch to another list and see if you encounter the same problem.

See my test results below:

Differential equations – Error message when trying to solve 2 coupled PDEs with NDSolve

I am currently facing a problem when I try to solve 2 paired PDEs. I get the warning messages:

NDSolve :: fembdcc: The cross coupling of dependent variables in DirichletCondition (IPF == IPB / 10, z == 5.) ​​is not supported in this version.

NDSolve :: fembdcc: The cross coupling of dependent variables in DirichletCondition (IPF == IPB / 10, z == 5.) ​​is not supported in this version.

Here is the code I'm using:

 FirEqn = -D(IPF(z, t), z) - D(IPF(z, t), t)  - IPF(z, t)

 SecEqn = -D(IPB(z, t), z) - D(IPB(z, t), t)  - IPB(z, t)

 solIntEqn = 
      NDSolve({FirEqn == 0, SecEqn == 0, 
        IPF(0, t) == 4 Exp(-(t - 1)^2), 
        IPB(0, t) == 4 Exp(-(t - 1)^2)/RICP, 
        IPF(5, t) == IPB(5, t)/ROCP}, {IPF, IPB}, {z, 0, 5}, {t, 0, 10});

I know the problem is when I specify the constraint for z == 5, but that's one of the requirements that I need. Any help is asked! Cheers.

By the way, I use version 11.2

Migration – Error copying all PostgreSQL databases between servers, although no error message is displayed

I want to copy all databases from PostgreSQL 9.3 on server-1 (Windows 7) to an empty one PostgreSQL 12.0 on server-2 (Windows Server 2012 R2). The steps are as follows:

  1. On server-1:

    C:Program FilesPostgreSQL9.3bin>pg_dumpall.exe -U postgres -W -f fulldump.sql
    
  2. Copy fulldump.sql from server-1 to server-2.

  3. On server-2:

    C:Program FilesPostgreSQL12binpsql.exe -f fulldump.sql -U postgres
    Password for user postgres:
    

No error message appears, everything seems to be OK. However, none of the databases appear in PostgreSQL 12.0 of the new server-2. Unfortunately, as far as I know there are no suitable questions in this forum from which I could draw some pointers. What is missing from my workflow?

Did Trump join the Republican Party because he knew Democrats were too smart to believe his message?

Fact checkers have documented over 15,000 cases of Trump misinformation and lies. Trumpsters are one of the following:

1] Too unintelligent to know the truth.

2] They know Trump is a pathological liar, but they don't care because he's on your team.

3] You agree with its evil and greet it as a feather bird.

The Dems had long held Trump accountable for them. It never would have worked.

Understand, Trump's lies, attacks on democracy, messages of nationalist hatred, reprehensible fiscal irresponsibility, etc. are now part of the GOP image.

Sockets – Why does the HTTP client send empty data in the ACK message of the three-way handshake?

I am using Wireshark and find that my browser connects to a website, sends an empty ACK packet (and not an ACK packet with an http request).
Why does it happen? In TCP and HTTP RFCs, it is not forbidden to send ACK packets with data.

Is there also a way to enable / disable sending an ACK with data in socket programming?

strange message from the phone number but it was no sms

I received a strange message today. My phone vibrated and on the locked screen in the top bar I saw the same symbol as when I received conventional text.
When I unlocked the screen, I saw something like Popup (or Modal), but it was pinned at the bottom. There was a phone number in the header. There was text in the middle, but not everything was cut off. In the lower area there were two buttons for canceling and saving.
unfortunately i pressed the cancel button and now i cannot find this message in the system.
I thought it was a traditional SMS, so I didn't save it.
The administrator of my personal data had to look for something in the content, so it is important to me
Anyone can tell me where I can find this message or what type of message it is? From the network operator?

8 – Pop-up message does not come

I use the "Popup after login" module to display a popup after the users have logged in.

I want to display a YouTube video in the popup.

I carried out the following steps after installing and activating the module:

  • Go to admin / config / popup_after_login
  • Configure it by selecting the role in which the message should appear
  • Enter title and message text and save
  • Clear the cache and log in with an account that is assigned this role

I used the YouTube embed code for the video.

        );

The output is not displayed.

I checked that the PHP code is running and added the following code.

        

Again only the title was shown, not the message.

Please help.

Linux – Need Help? – I uninstalled Intel Optane Memory. – The message says that my computer no longer starts after the restart

I uninstalled Intel Optane Memory because I was convinced that this would affect the creation of a dual boot system with Linux on a Lenovo Ideapad 330S 151KB (based on a guide). There was a warning about possible data loss and a checkbox to read about it. I checked the box and selected next. The text file says that my system cannot boot after a restart. The uninstallation of the application continued with the opening of the text file. (!!!)

I created a restore point just before I started this uninstallation. The uninstallation window is still waiting for the restart. I made two backups of all my data (not the operating system). I really don't want to have to reinstall Windows and Office and all licenses etc. etc. No CD / USB with the operating system was supplied on the computer. I realize that I can download Windows – I need to research how to do it. This is a one year old computer that came with Windows 10 (not Office). (I have Ubuntu on an external SSD, and it has grub on the SSD, not on my internal hard drive. So that should still work. I actually did the installation with a physically separate internal hard drive.)

Can I undo that? Can I restore to this restore point now?

Any help is greatly appreciated.

The warning text document – you must show this FIRST! (This is incredible – they warned about data loss, but not a non-bootable system):

WARNING!!!!!!!!!!!!WARNING!!!!!!!!!!WARNING!!!!!!!WARNING!!!!

WARNING: Removing the driver files may result in the loss of 
data on any RAID volumes currently used by the system. Removing 
the Intel Rapid Storage Technology driver from the boot drive or 
bootable RAID volume will remove access to the drive and will 
require reinstallation of the operating system. To preserve data
integrity, backup all data before proceeding.

Proceed ONLY if you absolutely have all your required data
backed up from all single drives and RAID volumes present in the
system and ONLY if you have no need to access these drives or 
volumes after this operation is completed!!! If this is not the
case, please cancel and exit this Uninstall application.
