Very strange of Mathematica!

The following two expressions are the same when checked numerically.

fun1[x_, y_] =    1/4 (Sqrt[(1 - y)/(       4 + y (-4 + (1 - 2 x)^2 y))] (2 - y + Sqrt[         4 + y (-4 + (1 - 2 x)^2 y)]) -       2 ((-1 + 2 x) y + Sqrt[         4 + y (-4 + (1 - 2 x)^2 y)]) Sqrt[-(((-1 + y) (-2 + y + Sqrt[           4 + y (-4 + (1 - 2 x)^2 y)])^2)/(4 -           4 y + ((-1 + 2 x) y + Sqrt[            4 + y (-4 + (1 - 2 x)^2 y)])^2)^2)]); fun2[x_, y_] = Sqrt[1 - y]/2; 

However, Mathematica is not able to reduce fun1[x,y] to fun2[x,y], with Simplify of FullSimplify. Is there any way of doing this simplification? Also note that $ 0\le x \le 1$ and $ 0\le y\le 1$ .

WP_Query: “post_parent” and “post_type” combination returning strange results

I’m experiencing some interesting results using post_parent along with post_type (local, WP 5.8):

I have a custom post type project (with 'hierarchical' => true) where I’m grabbing all child posts of a parent on a single view using WP_Query.

When setting post_type to project while setting post_parent I get the same results as if I had not set a post_parent at all: that is, I get all top-level posts with a custom post type of project.

If I set the post_type to any then I get the correct child posts. I have already checked to make sure that the $ post->ID for the parent is correct (and not 0) and that the posts are all of the same custom post type. I’ve also double checked the DB for weirdness and verified the parent-child relationships.

To make this stranger, this is on my local; the previous code (setting post_parent AND post_type) works fine on a live/production site (though that’s on an earlier WP version).

This is the query:

$  args = array(     'post_type'   => 'project',     'post_status' => 'publish',     'post_parent' => $  post->ID,     'posts_per_page' => -1,     'orderby' => 'menu_order title',     'order' => 'ASC' );  $  projects = new WP_Query( $  args ); if( $  projects->have_posts() ) :     while( $  projects->have_posts() ) :         $  projects->the_post();         the_ID(); 

As described, if I change to 'post_type' => 'any', then I get the correct child post(s).

What am I missing? Is my data corrupted (though I can’t see any evidence of this)…

Strange Variations of URL Showing Up in Google Search Console

My wife and I started a website several months ago. Today on Google Search Console we noticed some strange variations of pages on her site. They were found under the section:

Coverage > Crawled – currently not indexed

They look something like the following with our domain and some weird words appended to the end:

example.com/detroitchicago/raleighz.js?gcb=195-0&cb=5

example.com/porpoiseant/jellyfish.webp?a=a&cb=0&shcb=34

example.com/detroitchicago/edmonton.webp?a=a&cb=0&shcb=34

example.com/detroitchicago/memphis.js?gcb=195-0&cb=10

example.com/detroitchicago/minneapolis.js?gcb=195-0&cb=3

These pages just load up a bunch of gibberish code.

enter image description here

When I go to the referring pages and do a find, I don’t see any mention. However, if I do an inspect in my Chrome browser and search for string "detroitchicago" then a handful of results show up.

enter image description here

Was the website hacked? I don’t see any directories like "detroitchicago" in my hosting file manager when I search for it, but it seems to be in the page code.

What can I do to fix this problem and prevent it from happening? Do I just submit a new request to remove these strange URLS in Google Search Console?

VERY strange issue with Instagram

There's a strange bug I've been hitting lately on Instagram.
Certain mutual followers not showing up, or very far down the list.

Say there is an account @x that is followed by a close friend of mine (@y). I follow @y and @y follows me back. It doesn't matter if I follow @x or not.

Before, when I would open @x's page, I would see "Followed by @y, @z + 42 more". But that no longer happens. For some reason @y is not in this short list of mutual followers. Also, when I open the full list of…

Making the Ancient One from Dr. Strange [closed]

After seeing her in action in the movie, it looked like a fun character to try and make. Though, despite being called the sorcerer supreme, she feels like a variant of monk (with the magister template from Faerûn) while Strange himself is more of a wizard.

So, what would be the best direction to start for a melee/conjured weapon character that can port around on this plane and others, as her situations require? Sorry to be a nuisance if this or similar post has been asked already

Strange problem

I don’t know if anyone else has this bug , but I’m on a vps via rdp and SER just disappears from the desktop yet its still running in taskmanager. Theres no icon on the taskbar, I cant bring it back to focus and the only way to shut it down is via taskmanager.

Strange behaviour on stored procedure

I have the following mysql stored procedure:

DELIMITER // CREATE PROCEDURE INSERT_INTO_WORKDAY(IN deviceName VARCHAR(16), IN cardUID VARCHAR(14))  BEGIN     SET @projectId = (SELECT MIN(ID) FROM PROJECT WHERE DEVICEID = (SELECT MIN(ID) FROM DEVICE WHERE NAME = deviceName) ORDER BY ID DESC LIMIT 1);     SET @workerId = (SELECT MIN(ID) FROM WORKER WHERE CARDNUMBER = cardUID);     SELECT @workerId;          SET @id = (SELECT MIN(ID) FROM WORKDAY WHERE WORKERID = @workerId AND PROJECTID = @projectId AND STOPTIME IS NULL AND STARTTIME IS NOT NULL);     IF (@id >= 0)         THEN             UPDATE WORKDAY SET STOPTIME = now() WHERE ID = @id;     ELSE         INSERT INTO WORKDAY (WORKERID, PROJECTID, STARTTIME) VALUES (@workerId, @projectId, now());     END IF; END; // DELIMITER ; 

When I call the procedure once, I get the result:

mysql> CALL INSERT_INTO_WORKDAY("Pepper_C1-1A6318", "045D91B22C5E80"); +-----------+ | @workerId | +-----------+ |         1 | +-----------+ 1 row in set (0.01 sec)  Query OK, 1 row affected (0.09 sec) 

From second run, is not working anymore:

mysql> CALL INSERT_INTO_WORKDAY("Pepper_C1-1A6318", "045D91B22C5E80"); +-----------+ | @workerId | +-----------+ |      NULL | +-----------+ 1 row in set (0.00 sec)  ERROR 1048 (23000): Column 'WORKERID' cannot be null 

I did try to isolate and run the procedure with only this two lines of code:

    SET @workerId = (SELECT MIN(ID) FROM WORKER WHERE CARDNUMBER = cardUID);     SELECT @workerId; 

And it behaves just like above, but if I try to run SELECT MIN(ID) FROM WORKER WHERE CARDNUMBER = "045D91B22C5E80"; alone, works without problems. The @projectId variable behaves normal everytime I call the stored procedure.

Can someone help me to find a solution? Thank you!

My setup:

mihai:~$   mysql -V mysql  Ver 8.0.22-0ubuntu0.20.04.3 for Linux on x86_64 ((Ubuntu))

AnglePath strange behaviour

I’ve noted that AnglePath behaves differently according to the length of the argument.

It seems that when the steps are less than 100 the output can be a list of _Integer coordinates, otherwise the output is always a list of _Real coordinates and sometimes with gratuitous errors too.

Do[If[And @@ MatchQ[#, {_Integer, _Integer}] & /@ AnglePath[ConstantArray[0, i]], , Print[i]; Break[]], {i, Infinity}];  (* 100 *) 

In this example when the angles are all 0° the path is a straight line and the list of 2D coordinates is:

  • {{0,0},{1,0},{2,0},...} with less then 100 steps
  • {{0.,0.},{1.,0.},{2.,0.},...} with more then 99 steps

But something even more unreliable arises when right angles are used:

Last@AnglePath[ConstantArray[90°, 96]] (* {0,0} *)  Last@AnglePath[ConstantArray[90°, 100]] (* {-1.25677*10^-13, -1.3824*10^-13} *)  Last@AnglePath[ConstantArray[90°, 10000000]] (* {0.00189154, 0.00189872} *) 

Is this intended or known?

What is the “strange platypus-like creature” referenced in abberant mind’s origins?

I don’t recall any “strange platypus-like” creature in D&D, let alone one appropriate for the Aberrant Mind. I can only think of Perry the Platypus from the Phineas and Ferb cartoon. Nevertheless the Abberant Mind’s origins describes such a creature:

As a child, you had an imaginary friend that looked like a flumph or a strange platypus-like creature. One day, it gifted you with psionic powers, which have ended up being not so imaginary.

The Flumph is name checked, and I’m aware of that creature. What is the other one?

Why do I get strange symbols in the article?

Hello guys!
I just edited the file: auto_anchor-article.dat, for example from English to Portuguese.
I did a test with an article to get the preview – minimal, and the article shows strange symbols, see image.

Those symbols are shown in the article.

I think it’s because of the accents.
My question is: will these symbols appear at the end of the campaign (articles, webs, wiki …) or does it only show in the preview?
