Sitemap can be read, but has errors

I recently did some changes to my sitemap because i updated my website to support two languages but now i get an error when submitting the sitemap and i don’t see where the problem is.

Your Sitemap or Sitemap index file does not properly declare the namespace. 
>     Examples >     Line 5 >     Parent tag: >     url >     Tag: >     link        <urlset xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.sitemaps.org/schemas/sitemap/0.9" xmlns:xhtml="http://www.w3.org/TR/xhtml11/xhtml11_schema.html" xsi:schemaLocation="http://www.sitemaps.org/schemas/sitemap/0.9 http://www.sitemaps.org/schemas/sitemap/0.9/sitemap.xsd http://www.w3.org/TR/xhtml11/xhtml11_schema.html http://www.w3.org/2002/08/xhtml/xhtml1-strict.xsd">     <url>     <loc>https://example.com/</loc>     <xhtml:link rel="canonical" href="https://example.com/"/>     <xhtml:link rel="alternate" hreflang="el" href="https://example.com/"/>     <xhtml:link rel="alternate" hreflang="el-GR" href="https://example.com/"/>     <xhtml:link rel="alternate" hreflang="x-default" href="https://example.com/"/>     <xhtml:link rel="alternate" hreflang="en" href="https://example.com/en"/>     <lastmod>2020-02-25T12:41:35+00:00</lastmod>     <priority>1.00</priority>     </url>              ````````           </urlset> 

***Update

Tried this method like the Google Documentation says so

<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"   xmlns:xhtml="http://www.w3.org/1999/xhtml"> 

Although when using xmlns:xhtml="http://www.w3.org/1999/xhtml" converts the xml to plain text, changing http to https outputs the xml correctly and does the work but i have read you must use only http to avoid my issue, honestly this it too confusing.

Is there a use for a READ COMMITTED READ ONLY transaction?

A READ COMMITTED (the default isolation level) transaction will acquire a new snapshot for each query. In a READ ONLY transaction, could you not just omit the transaction entirely and have no real difference in behaviour?

You can’t use SELECT … FOR UPDATE, but you can use LOCK [TABLE], which would last until unlocked or the transaction ends. So there’s one difference. Are there other differences?

If a DB table is 3TB in size and read speed is 10mbyte/sec. Does it mean that 83hours are necessary to create new index?

One of our custom log tables is 3TB in size. We need to create a new index. Read speed on the disk itself is 10mbyte/sec.

Does this mean that the index creation process will be 3.000.000/10 = 86 hours? The index is written to another filegroup on a fast disk so write time is not a factor.

Read actor instance’s text variable for widget when triggered on different objects

What I’m trying to do: (a ‘long story version’ is linked in comment below)

(and another user example is hyperlinked in comment below – i couldn’t post over 8 images and/or links in this first comment*) (there are other similar user questions elsewhere I know)

Short story: I’m trying to make a widget that is triggered by an actor blueprint, and I want the widget to display different text that reflects the public-variable-text edits I make in the editor.

My latest progress includes actors that are titled somewhat according to the hyperlinked user case above so, I have a "door_trigger" and a "doorWidget". I have altered the pin connections so much that I am just going to copy and paste all my screen shots below.

I got to change text asset DoorName by making a public variable called "name," as you’ll see. I can make the trigger show this text on screen and have it disappear when the user leaves the trigger actor, BUT EVERY INSTANCE ALSO SHOWS THIS TEXT VALUE, EVEN THOUGH I CHANGE IT

In the screenshots (some in comment following too) you’ll see the text "3" appear on screen, and it does this for all three of the dummy boxes I made; notice how the second box is supposed to show "dd" (I was just typing random filler content).

ALL HELP SO APPRECIATED!!!!! Thank you!!!

Saving data from for loop to file and then read the data and plot graphs

I have a for loop which generates random matrices, then performs a few calculations to yield a bunch of different values. Essentially, something like so: For[j = 1, j < 100, j++, a={{1}{2}{3}{4}},b={{5}{6}{7}{8}},c=Tr[a],d=Tr[b], e=c+d, {a,b,c,d,e}>>> file]

Of course in the above, we repeat the same values over and over, I am using this as an example as the script would be too long and requires a list of different packages. I need to save these values to a file in a way that I can then extract the values and create a bunch of different graphs. What is the best way to go about this?

Read specific fields from Postgres jsonb

I have data like

{"name": "a", "scope": "1", "items": [{"code": "x", "description": "xd"}, {"code": "x2", "description": "xd2"}]} {"name": "b", "scope": "2", "items": [{"code": "x", "description": "xd"}]} {"name": "c", "scope": "3", "items": [{"code": "x", "description": "xd"}]} {"name": "d", "scope": "4", "items": [{"code": "x", "description": "xd"}]} 

Now I want the result like:

{"name": "a","items": [{"code": "x"}, {"code": "x2"}]} {"name": "b","items": [{"code": "x"}]} {"name": "c","items": [{"code": "x"}]} {"name": "d","items": [{"code": "x"}]} 

How can I stop all files being read only to PHP? [migrated]

I’m setting up a new Centos 7 server to run some legacy sites on PHP 5.6.40 through PHP-FPM with Nginx.

However, I’m running into a problem that all files are appearing to be read only.

PHP is running under the nginx user, the site directory is owned by nginx, and I’ve tried verious file permissions through chown, including "777".

I created a simple program to illustrate:

<?php $  fileList = glob('*');  //Loop through the array that glob returned. foreach($  fileList as $  filename){    //Simply print them out onto the screen.    echo $  filename;    if (is_writable($  filename))       echo ' - Yes!';    else       echo ' - No.';    echo '<br>'; } 

This will output the files in the site directory, with "No" next to each filename.

Any tips on what might be causing this, or how I might be able to debug would be greatly appreciated.

Repeatable read: the transaction may not be serializable with respect to other transactions

The text below is from ‘Database System Concepts, Silberschatz. I can’t understand the bolded part. How the transaction may not be serializable with respect to other transactions? And also how a transaction may find some of the data inserted by a committed transaction, but may not find other data inserted by the same transaction?

Repeatable read allows only committed data to be read and further requires that, between two reads of a data item by a transaction, no other transaction is allowed to update it. However, the transaction may not be serializable with respect to other transactions. For instance, when it is searching for data satisfying some conditions, a transaction may find some of the data inserted by a committed transaction, but may not find other data inserted by the same transaction.

SQLServer: Why is a Shared lock blocking on an IX lock when Read Committed Snapshot is enabled?

Our system has randomly started deadlocking in areas where it previously had not, and an analysis of the deadlock graph looks like it should not even be happening to begin with. Here is a screenshot of the deadlock graph.

enter image description here

For reference: The left node is a basic insert into the sync_entities table, where the right node is "update sync_entities set A=B, C=D from sync_entities e join sync_revisions r on e.id=r.entity_id where r.id in ()"

Based on my understanding of lock compatibility, an Requesting an S lock when an IX lock exists would block only if Read Committed Snapshot is off, but it is turned on for this database, and has been for a very long time. Am I missing something?
