Can the default SharePoint collections in Office 365 be safely deleted?


This is the default site collection in which you can create your Intranet. It is the perfect place to create new team sites, service sites, document management sites. You don't need to use this particular site collection for Intranet, and you can always create a new one (more on that later in the post), but this one has it Cleanest (shortest) URL that's easy to remember!

The second site collection in the list is / portals / hub. This is a site collection that contains all the videos that you would post to the Office 365 video portal. I wrote a detailed article on Video Portal – check it out. Office 365 Video Portal is like an internal YouTube for your organization. You can publish all kinds of videos and organize them by channels, like on YouTube. It can be very useful for training, marketing and other corporate videos.

You can see or not this collection of sites in the list. If you do, this site collection is a dedicated space with the community features enabled. It allows administrators to manage discussions in a virtual environment. Honestly, I don't see this feature used by many organizations, so I wouldn't sweat it if I were you. Just know what this site collection is in case you see it, and let's move on! If you have free time, you can read more about this site collection here (official Microsoft article).

This is the site collection responsible for searching your SharePoint environment. Whenever you search in your SharePoint (i.e. using the search box in the upper right corner of the SharePoint site), this site collection (officially known as the Search Center ) processes the requests and displays the results for users. If you've always wanted to adjust how your search results are displayed or how the search query / logic works, you would modify the Search Center (this particular site collection). You can also create additional research centers (site collections) to provide users with an alternative search experience, but that is the subject of some future blog posts.

Recover deleted records from ibdata1

Is it possible to recover deleted lines from ibdata1? I only have the ibdata1 file and no other files or tables. I want to recover all the table structures and data with the deleted records. Is it possible?

What does it mean if a generic structure is deleted by type?

This documentation indicates that the generic structure AnyIterator is a deleted type iterator Element.

matrices – Determinant of the Vandermonde matrix with deleted lines

Given a partition$ lambda = ( lambda_1, lambda_2, cdots, lambda_n) $, or $ lambda_1 geqslant lambda_2 geqslant cdots lambda_n $and every $ lambda_j $ is a non-negative integer, the Vandermonde matrix with deleted lines can be defined by

$ mathbf {V} = left ( begin {matrix} x_1 ^ { lambda_1 + n-1} & x_2 ^ { lambda_1 + n-1} & dots & x_n ^ { lambda_1 + n-1} \
x_1 ^ { lambda_2 + n-2} & x_2 ^ { lambda_2 + n-2} & dots & x_n ^ { lambda_2 + n-2} \
vdots & vdots & ddots & vdots \
x_1 ^ { lambda_n} & x_2 ^ { lambda_n} & dots & x_n ^ { lambda_n} end {matrix} right) $


The determinant of the matrix $ mathbf {V} $ can be determined by Schur's polynomial. However, from Jacobi-Trudi identities, the determinant of the matrix $ mathbf {V} $ is simply expressed as a determinant in terms of elementary symmetric polynomials, which is still difficult to verify if the determinant is zero or not. Is there a way to check if the matrix $ mathbf {V} $ is it complete or not?

c # – Error & # 39; The object cannot be deleted because it was not found in ObjectStateManager. & # 39;

I have the following instructions to delete an Entity Framework object linked to an Oracle database:


and the mentioned error comes out:

I also used the attachment as it shows

context.CONCEPTO.Entry(objConceptoBasico).State = EntityState.Deleted;

BUT it tells me an error in entutystate.deleted, even for editing EntityState.Modified;

I use the EF 5 database first

Is OpenGL obsolete or deleted in Catalina?

OpenGL is officially not recommended by Apple from macOS Mojave 10.14. However, Apple still maintains the standard.

OpenGL and OpenCL

OpenGL and OpenCL were officially deprecated to Mojave last year, although this is a bit misleading as it implies that Apple had actively maintained and updated its support for these standards. In Catalina, as in all versions of macOS going back to Mavericks, the implementation of macOS OpenGL is blocked at version 4.1 (2010) and the OpenCL version is blocked at 1.2 (2011). This means that applications that still depend on these APIs on macOS will continue to work, provided they have been updated to meet the 64-bit requirement only. But you shouldn't be developing new Mac applications that rely on OpenGL or CL for something important.

The situation can be misleading for OpenGL developers. But Apple seems to be hinting whether or not they might support the technology in the future.

Google groups – The former member of our Google group has been deleted and cannot be added again!

One of our members accidentally deleted their account and when we are going to add it again we get this message: some email addresses cannot be added to this group because their accounts are disabled or blocked by Google Groups.
His email address is Outlook and he says he has no Google account.
Any suggestion?
thank you,

delete – Problem deleted on Jira containing all my wireframes?

I accidentally deleted a problem on Jira, containing all my 30+ wireframes created in the Balsamiq plugin.

Unfortunately, no backups were made to the Jira system, so I couldn't find a way to recover them.

Ideas? Thanks in advance.
