Kubuntu launch menu no longer takes keyboard input

Ever since I updated to 20.10 I can no longer search for applications in the KDE launch menu. The keyboard works fine for anything else and no amount of clicking on the search bar makes it take input.

visas – How many days it takes to receive a passport by an express courier return?

I have applied for a UK visa in Paris and I am wondering whether I should choose the express courier return service or not. I have already been troubled a lot by Covid-19 and I want to receive the passport as soon as possible after the decision has been made. However, I am afraid the TLSContact courier service will take too long, or perhaps it may not be something to trust very well. For those who know, how many days it usually takes for such a service to deliver a passport?

applications – I installed a large app & it won’t install but takes my storage! now I have full storage but haven’t the app?

I’ll be grateful if someone help me! I installed a large app (1.25 G a game) but it won’t install because of my low storage it won’t install said app not installing just like this; but take my storage! now I have full storage but haven’t the app I already cleared the game app and restart my phone but didn’t worked…
I use ES filemanager & always check my storages; before installing that app my storage 79% but now 92% I already searched my internal-storage for any tail of the game but it was nothing.
Btw I have to say I did something like this before and it fixed by itself I think after a little time Im not sure already… Ô×íMy own files pictures, videos ets CAN’T BE 92% its about 600mbs my interal-storage is shown 10.50G & except this I have 2.65Gb installed apps
I have sd card 64G too.
!!!???

I am trying to understand a python function that takes a list and rearranges the elements in the list

I am trying to understand what change += change >= i does in this python code.
The purpose of this code is to take a list and return it but with rearranged element positions.

import random
def random_shuffle (lst):
    len1 = len(lst)
    for i in range(len1):
        change = random.randrange(len1 - 1)
        change += change >= i
        lst (i), lst(change) = lst(change), lst(i)
    return lst

number theory – A Diophantine Equation-like Problem that takes consecutive integer values

Let $(a,b)$ denote all integers between $a$ and $b$.

For $c_1,c_2inmathbf{Q}setminus {0}$, define
begin{equation*}
f(x,y)=frac{xy}{c_1x+c_2y} quad text{for}; (x,y)neq(0,0)quadtext{and};; f(0,0)=0.
end{equation*}

on a set $Ssubset (a,b)times(c,d)$ including $(0,0)$, for some integers $a,b,c,d$. The lattice points set $S$ satisfies:

(1) $f(S)=(u,v)$ for some integers $u,v, v-ugeq 2$, namely $f(x,y)$ is an integer for all $(x,y)in S$ and the range consists of consecutive integers with at least three of them;
(2) The projection of $S$ onto $x,y-$axis are $(a,b)$ and $(c,d)$, respectively;
(3) If $(x_1,y_1),(x_2,y_2)in S$, then $x_1y_2=x_2y_1neq 0$ never happens.

I suspect that the parameters $c_1,c_2,a,b,c,d,S,u,v$ as above do not exist, but have no idea disproving it. Can anyone give some ideas for it? Thanks a lot.

multi classing – Does a PF2e spellcaster who takes multiclass dedications into other spellcasting classes, and related spellcasting feats, gain more spell slots?

Ezren is a level 10 evocation wizard, and hence would have spell slots of the following levels:

+-------------+-----------------+
| Spell level | Number of slots |
+-------------+-----------------+
|           1 |               4 |
|           2 |               4 |
|           3 |               4 |
|           4 |               4 |
|           5 |               4 |
+-------------+-----------------+

However, at level 2 Ezren took the Sorcerer multiclass dedication. At level 4 he took Basic Sorcerer Spellcasting, and Bloodline Breadth at level 8.

How many spell slots does Ezren have in a given day? Is it:

+-------------+-----------------+
| Spell level | Number of slots |
+-------------+-----------------+
|           1 |               6 |
|           2 |               6 |
|           3 |               6 |
|           4 |               4 |
|           5 |               4 |
+-------------+-----------------+

Because at level 8, spellcasting archetype feats grant an additional spell slot of first, second and third level, AND the bloodline breadth feat increases each of these by one?

Or do these sources of spell slots not stack for some reason? Coming from fifth edition, a wizard who multiclasses sorcerer still has the same number of spell slots as a pure wizard, so I’d like to clarify my understanding here.

dnd 5e – What is damage you do vs. damage a creature takes? (and Dark One’s Blessing)

The Warlock ability Dark One’s Blessing says (emphasis mine)

Starting at 1st level, when you reduce a hostile creature to 0 hit points, you gain temporary hit points equal to your Charisma modifier + your warlock level (minimum of 1).

Is there a general ruling on who or what is the author of damage? Most spells and attacks are written to describe how the target takes damage, rather than how the attacker does damage. I think it is safe to assume that an attack you make or a spell you cast is you doing damage, but I am unsure on how to rule in a more abstract example, such as forcing an interaction with a damaging environment.

Consider the following hypotheticals. None of them are my specific question, but serve to illustrate what I am trying to come to terms with. My question is whether there is a general underlying principle in the game that assigns authorship to damage.

For example, suppose oil has been spread on the floor and a hostile creature chooses to cross it. My warlock throws a lit torch into the oil and the DM requires an attack roll. The subsequent fire reduces the creature to 0hp. Does the warlock get to use Dark One’s Blessing?

Suppose the same warlock lights a nearby patch of oil on the floor and the DM does not require an attack roll. A hostile creature later chooses to enter the burning oil and is reduced to 0hp. Does the warlock get to use the ability? Did he reduce the creature to 0hp, or did the fire? Does it matter that the creature chose to enter the fire through its own movement – if the warlock had been able to use a spell or action to force the movement, would the answer be different?

Finally, consider three warlocks who all have initiative before a target. One throws a flask of oil on the floor, one throws a torch that ignites the oil, and one uses a shove attack to move a hostile creature into the space where the flaming oil is / will be. Which warlock(s) get to use Dark One’s Blessing? Does their order matter? That is, is it a different answer if the shove moves the creature to the space where the oil will be, vs. to a space where the flame already is?

Possibly related: If my familiar is forced through my action to drop a rock while over a target, is it considered an attack?

files – ExtensionDiscovery::scanDirectory() takes too long

I have been debugging a bit an issue on our platform and I notice that our scanDirectory takes, from time to time, way to long, more than 100seconds.
I have been looking at the default.settings.php and I noticed

/**
 * The default list of directories that will be ignored by Drupal's file API.
 *
 * By default ignore node_modules and bower_components folders to avoid issues
 * with common frontend tools and recursive scanning of directories looking for
 * extensions.
 *
 * @see file_scan_directory()
 * @see DrupalCoreExtensionExtensionDiscovery::scanDirectory()
 */
$settings('file_scan_ignore_directories') = (
  'node_modules',
  'bower_components',
  'vendor',
);

I found that out that our sites/default directory is the one to blame.
Can I just add it here? Or should I include the subdirectories(fx sites/default/files)?

I am really surprised about this one. Been working with drupal years now and I see this first time!
