No longer able to access Data Source Details when creating an empty data view web part using Sharepoint Designer

Using SharePoint Designer 2013 I can no longer access a list data source on SharePoint Online when building a DVWP

Steps to reproduce.

  1. In SPD create a new Web Part Page.
  2. Edit the new page in Advanced Mode.
  3. Place cursor in ZoneTemplate tag.
  4. Click Insert -> Data View -> Empty data view.
  5. Place cursor in newly create DataSources tag.
  6. Click Insert -> Data Source -> and select a list.
  7. In the data source pane click refresh Data source link

error The server returned a non-specific error when trying to get data from the data source. Check the format and content of your query and try again. If the problem persists, contact the server administrator

Ran a fiddler session. get 500 response on. /_vti_bin/webpartpages.asmx.

soap:ServerException of type ‘Microsoft.SharePoint.SoapServer.SoapServerException’ was thrown.An error has occurred.

Also tried to refresh a data source on an existing DVWP with same result.

Anybody experiencing this issue?

Removing grants for datbases that no longer exist

We have quite a few MariaDB servers with whom the permissions have gotten a bit messy over the years. I’d like to tidy them up.

I’ve already written some tools for presenting grants/table information nicely, and this has highlighted that that some users have a LOT of specific grants for databases or tables that no longer exist. On one server there are over 150 databases referenced by users in SHOW GRANTS, but only 12 databases still exist.

How might the users of Stackoverflow deal with housekeeping of this order?

Are there any tools that do basic auditing on Grants, accesses and Databases that will help me sort through this mess?

Ideally, something that spits out a list of mysql REVOKE statements that remove grants for databases that no longer exist, that can then be reviewed by a human before pasting as a query.

I can see a way to anagrammatically sorting through them, but it is likely to take a few hours to write that up. It may still come to that but I’d like to know if this wheel has already been invented.

Is it possible to make a row longer? I am trying to make our picture notification types look longer

Example

We release notifications to our users to show them the risks of phishing scams. For our notifications, we put pictures in the “notification type” field to draw attention. To do so, we use a link to the photo. Does anyone have a workaround or a better way to make these pictures look larger?

Why does ubuntu 16.04 takes longer time to open applications than windows 10?

I am using a SSD as a boot drive. I recently switched from windows 10 to ubu ntu 16.04(newer version of ubuntu dont run smoothly on my laptop as its 5+ years old) and I noticed that it takes more time to boot and open applications(spotify, chrome etc) than windows 10. Why is that and what can I do to make it run smoothly as windows 10?.

Note:- I have installed preload and it does not help me much.

When are derivatives no longer relevant?

This is a non-research, weekend-night question. Feel free to close it.

Q. Which high-degree derivatives play an essential role in applications, or in theorems?

Of course the 1st derivative of distance w.r.t. time (velocity), the 2nd derivative (acceleration), and the 3rd derivative (jolt or jerk) certainly play several roles in applications. And the torsion of a curve in $ \mathbb{R}^3$ can be expressed using 3rd derivatives.

Beyond this, I’m out of my depth of experience. I know of the biharmonic equation $ \nabla \phi^4=0$ . There is a literature on the solvability of quinitics, but it seems this work is neither aimed at applications nor essential to further theoretic developments. (I am happy to have my ignorance corrected here.)

Q. What are examples of applications that depend on 4th-derivatives (snap/jounce) or higher? Are there substantive theorems that require existence of $ \partial^4$ or higher as assumptions, but do not require (or are not known to require) smoothness—derivatives of all orders?

using 2 short CRC(s) VS one longer CRC

I’m doing some research on the CRCs, but i can’t find informations about the use of two (or more) short CRCs compared to the use of a longer CRC:

Suppose that i have a dataword A of some length and 3 different generator polynomials, 2 of degree 8 and one of degree 16. These polynomials are used respectively by CRC1, CRC2 and CRC3 algorithms, where CRC1 and CRC2 generate 8-bit codes while CRC3 generates 16-bit codes.

Suppose also that the three CRC have the same Hamming Distance for datawords of the same size.

now consider these 2 options:

  1. Compute CRC1(A)=x1 and CRC2(A)=x2 and use codeword A|x1|x2 (where ‘|’ means concatenation);

  2. Compute CRC3(A)=y and use codeword A|y;

what are the advantages and disadvantages of the first approach in respect to the second?

Please provide also some references if you have them!

Can’t place WhatsApp calls as I’m told my phone number is no longer registered

For the past several days, I can’t make WhatsApp calls. When I try, I get a message saying:

Can’t place call because this number is no longer registered on WhatsApp

So, I go to my account settings, and in “Two step Verification” it says:

For added security, enable two-step verification, which will require a PIN when registering your phone number with WhatsApp again.

So I guess I need to re-register my phone. But how? If I try “change number”, it won’t accept the same number, it has to be a different one. Except I don’t have a different number to use. And I definitely do not want to delete my account…

What do I do?

Relevant Details:
Phone: Xiaomi Redmi 3S
Android version: 6.0.1 (MIUI build 8.5.4.0)
WhatsApp version: 2.17.427

Makes Erections Harder And Longer Lasting

That marked the emergence of Hard Time FX.

I was really feeling the pressure as it respects Hard Time FX. Hard Time FX is hard enough without adepts making it harder for you.

That's often difficult. Some Hard Time FX might be objectionable. Hard Time FX is a commonly used process to complement Hard Time FX. I am only telling you how to do it. It stands to reason this isn't incorrect. It is conventional how big babies do not detail an…

How to remove duplicate words in a cell only if longer than a certain number of characters?

I need to remove a duplicate text in a cell but only if it is longer than 4 characters.

I have this formula that only works for any types of duplicate words:

=join(" ",unique(transpose(split(A1,", ")))) 

In this case, if a cell contains:

W3-X500 Samsung Galaxy W3-X500 5 inches and 5 different colors 

It returns me:

W3-X500 Samsung Galaxy 5 inches and different colors 

I will lose the second 5 character that instead I need.

How can I do it?

17.10.1 repository Artful Aardvark appears to have been changed and is no longer located where it was

Right now, I’m not concerned about Opera web browser. I did find this though:

http://old-releases.ubuntu.com/releases/artful/

How do I add this to the repository lookup when I do an update? I know I have to go into the “Software & Updates” part of the Software package program, and add it under “Other Software”. But it tells me it has to be a complete APT line, where

“The APT line includes the type, location and components of a repository, for example ‘deb http://archive.ubuntu.com/ubuntu artful main’.”

I’m at a loss as to what to do next. Should I downgrade to 16.04 seeing that it’s still supported? The only reason I upgraded to 17.10 was because I was having audio issues using 16.04. The logical solution would be to upgrade to 18.04, except my hardware might not be able to handle it.

Any help is greatly appreciated. Thanks.
