I'm using Geotools 30-SNAPSHOT and i would like to use ISO Geometry (from opengis package).
I'm using the following code to get ISO geometry related factories:
import org.geotools.geometry.GeometryFactoryFinder;
import org.geotools.referencing.crs.DefaultGeographicCRS;
import org.geotools.util.factory.Hints;
import org.opengis.geometry.PositionFactory;
import org.opengis.geometry.coordinate.GeometryFactory;
import org.opengis.geometry.primitive.PrimitiveFactory;
public class FactoriesSample {
public static void main(String[] args) {
PositionFactory positionFactory ;
PrimitiveFactory primitiveFactory;
GeometryFactory gf;
Hints hints = new Hints( Hints.CRS, DefaultGeographicCRS.WGS84 );
try {
positionFactory = GeometryFactoryFinder.getPositionFactory(hints);
} catch (Exception e) {
System.out.println("Cannot determine geometry factory: "+e.getMessage());
}
try {
primitiveFactory = GeometryFactoryFinder.getPrimitiveFactory(hints);
} catch (Exception e) {
System.out.println("Cannot determine primitive factory: "+e.getMessage());
}
try {
gf = GeometryFactoryFinder.getGeometryFactory(hints);
} catch (Exception e) {
System.out.println("Cannot determine geometry factory: "+e.getMessage());
}
}
}
My concern is that the execution of the previous code gives:
Cannot determine geometry factory: No factory of type "PositionFactory" has been found.
Cannot determine primitive factory: No factory of type "PrimitiveFactory" has been found.
Cannot determine geometry factory: No factory of type "GeometryFactory" has been found.
It seems that my project has no attached JAR that contains the factories. My maven dependencies are:

Can you please indicate me which dependencies are missing in order to get the factories or is there is an error within my code ?
Thanks a lot.
My school provides me with a Chromebook.
Today, I closed the lid, then opened it up, expecting to see the lock screen, but instead, I saw where I last left off. I thought it might be because I had used the super zoom (ctrl+alt+brightness) because that usually happens, but instead of working again, it just turned off, and won’t turn back on.
It is charging but should show the low battery error, which it does not.
Consider $R^3$ as an inner product space in relation to scalarmultiplication. Find all vectors in the subspace
$$Spanbigg(bigg[begin{matrix}1\2\1
end{matrix}bigg],bigg[begin{matrix}3\4\1
end{matrix}bigg]bigg)subseteq R^3,$$
which are orthogonal to the vector $bigg[begin{matrix}-1\1\1
end{matrix}bigg]$
Any help will be appreciated. I tried finding the random vector $v=bigg[begin{matrix}x_1\x_2\x_3
end{matrix}bigg]$ in the plane which i found to be ${x_3cdotbigg[begin{matrix}1\-1\1
end{matrix}bigg]bigg}$ but i dont know where to go from here.

It says HDR video enabled, use HDR not supported. The preview video in HDR control panel is blank. It says here there should be snowy mountains – https://support.microsoft.com/en-us/windows/calibrate-your-built-in-display-for-hdr-content-in-windows-de1c66fa-6cc0-b327-e73a-1bac6bd46bc0#WindowsVersion=Windows_11

The starting point was that $ Gamma'(x+1)=Gamma(x+1)psi(x+1)$ where $psi(x+1)=-gamma+H_{x}$ . Hence $$ [x!]’ = x!biggl[-gamma+sum_{k=1}^{x}frac{1}{k}biggl]$$ For example $ [4!]’ = 24[-gamma+1+1/2+1/3+1/4]$ which gives 36.1462 that, put in the tangent equation, gives us exactly the tangent for x=4! Let me know if I made any mistakes in the derivation/generalization!

It is very strange that this file exists, even I copy and paste its address in run and the file opens
Let $W_2(mu,nu)$ denote the $2$-Wasserstein distance between two given probability measures $mu$ and $nu$ on $mathbb R^n$. For a probability measure $mu$ and $f:mathbb R^nto mathbb R^n$, let $f_{#}mu=mucirc f^{-1}$ denote the push-forward of $mu$ under $f$, i.e. $(f_{#}mu)(B)=mu(f^{-1}(B))$ for every Borel set $B$ in $mathbb R^n$. Why does the following inequality hold true?
$$W^2_2(f_{#}mu,g_{#}mu)leq int_{mathbb R^n}|f(x)-g(x)|^2,dmu(x) $$
for all $mu$-measurable functions $f,g:mathbb R^ntomathbb R^n$.
Some comment: the product measure $f_{#}muotimes g_{#}mu$ is a so-called transport plan and by definition of the Wasserstein distance
$$W^2_2(f_{#}mu,g_{#}mu)leq int_{mathbb R^ntimes mathbb R^n}|x-y|^2,d(f_{#}muotimes g_{#}mu)(x,y)=int_{mathbb R^ntimes mathbb R^n}|f(x)-g(y)|^2,dmu(x),dmu(y).$$

My overall goal is to get a notification every time a file is copied or moved into a specific folder. I would like to try and avoid using external tools if possible. In order to achieve that I’ve created a task in task manager. This task should run every time a user copies or moves a file into this folder. I’m using the XML script that you can see below for the trigger.
Here is what ChatGPT spit out after several tries and refining of the request:
<QueryList>
<Query Id="0" Path="Security">
<Select Path="Security">
*[System[(EventID=4663 or EventID=4660) and
(EventData/Data[@Name='AccessMask'] = '0x2' or
EventData/Data[@Name='AccessMask'] = '0x1') and
(EventData/Data[@Name='ObjectType'] = 'File' or
EventData/Data[@Name='ObjectType'] = 'File (AD)') and
(EventData/Data[@Name='ObjectName'] = 'C:TA Data' or
starts-with(EventData/Data[@Name='ObjectName'], 'C:TA Data\'))]]
</Select>
</Query>
</QueryList>
When I copy or move a file into the folder the task doesn’t run.
Can someone help please?
I am currently studying construction of the Grothendieck group of a commutative monoid $M$. I was looking for an example of a monoid that is torsion, namely, I have the following query.
Does there exist a monoid $M$ (written multiicatively with identity element denoted by $1$) that is not a group such that $x in M$ implies $x^n = 1$ for some $n in mathbb{N}$?

i show similar posts based on tags:
//similar posts
$postID = get_queried_object_id();
$tags = wp_get_post_tags($postID);
foreach ($tags as $tag) {
//make array $xtag
$xtag[] = $tag->slug;
$count_tag = $tag->count;
}
$paged = ( get_query_var( 'paged' ) ) ? get_query_var( 'paged' ) : 1;
//echo $paged;
$args = array(
'exclude' => $postID,
'order' => 'ASC',
'orderby' => 'name',
'posts_per_page' => 2,
'paged' => $paged,
'tax_query' => array(
array(
'taxonomy' => 'post_tag',
'field' => 'slug',
'terms' => $xtag //apply $xtag array
)
)
);
$customPostQuery = new WP_Query($args);
//checking the max number of pages
echo $customPostQuery->max_num_pages;
//etc. printing the posts in a foreach loop
This works. Then i call a paging function, that should show similar posts by page:
if (function_exists("similar_post_pagination")) {
similar_post_pagination($customPostQuery->max_num_pages);
}
This is the similar_post_pagination function. It prints the pagination and when hovering the links also shows the correct links, but stays on page 1. I noticed that global $wp_query is empty. Apperently nothing happens here.
function similar_post_pagination($pages = "", $range = 2) {
$showitems = $range * 1 + 1;
global $paged;
if (empty($paged)) {
$paged = 1;
}
if ($pages == "") {
global $wp_query;
**//this is empty**
$pages = $wp_query->max_num_pages;
echo 'empty $pages '.$pages;
if (!$pages) {
$pages = 1;
}
}
if (1 != $pages) {
echo "<div class='archiv-pager'>";
if ($paged > 2) {
echo "<a class='page-numbers' title='" .
$first ."' href='" . get_pagenum_link(1) . "'><<</a><span>| </span>";
}
if ($paged > 1) {
echo "<a class='page-numbers' title='" . $prev . "' href='" . get_pagenum_link($paged - 1) . "'>< </a>";
}
for ($i = 1; $i <= $pages; $i++) {
$delimiter = " ";
if ($i > 1) {
$delimiter = "• ";
} else {
$delimiter = "";
}
if (
1 != $pages &&
(!($i >= $paged + $range + 1 || $i <= $paged - $range - 1) ||
$pages <= $showitems)
) {
if ($paged == $i) {
echo $delimiter . "<span class='page-numbers current'>" . $i . "</span>";
} else {
echo $delimiter . "<a class='page-numbers inactive' title='" . $page . $i . "' href='" . get_pagenum_link($i) . "' >" . $i . "</a>";
}
}
}
if ($paged < $pages) {
echo "<a class='page-numbers' title='" . $next . "' href='" . get_pagenum_link($paged + 1) . "'> ></a>";
}
if ($paged + 1 < $pages) {
echo "<span>| </span><a class='page-numbers' title='" . $last . "' href='" . get_pagenum_link($pages) . "'>>></a>";
}
echo "</div>";
} else {
echo '<div class="dummy-pager"></div>';
}
}
What do i have to use in this function for the pagination to work? Another query? Is it a scope issue? The same function works for archiv pages, but not for the similar posts.
Sorry about the length of this question and thanks for your interest. gurky
There is an answere about 3 rows here How to merge lines every 3 rows in Notepad++?
But this method doesnt work for 10
