Are the amount of spell slots per caster level derived with math or decided arbitrarily?
What spell slot count formula can I use to base my homebrew mechanic on?
How can I check for an empty/undefined/null string in JavaScript? Can you add new statements to Python's syntax? Can you add new statements (like print, raise, with) to Python's syntax?  Say, to allow..  mystatement "Something"   Or,  new_if True:     print "example"   Not so much if you should, but rather if it's possible (short of modifying the python interpreters code) Removing Ubuntu from a dual-boot setup with Windows Why does adding a curve modifier move my object to the center of the curve? I'm using a curve modifier and an array modifier. My object is at one end of the curve but as soon as I choose the curve for the curve modifier it moves to the center. How can I fix the problem so that I can have the array going from one end of the curve to the other? Sam Weller in The Pickwick Papers: What accent is Dickens portraying? In Dickens' Pickwick Papers, there's a character "Sam Weller". Weller's dialogue is written somewhat phonetically, I presume, but I'm struggling to understand what accent Dickens is trying to portray. The main peculiarities of Weller's speech are using "v" where there should be a "w" and a "w" when there should be a "v". For example, he says "wery" instead of "very" and "avay" instead of "away". Weller is supposed to be from London, but this doesn't seem like any kind of London accent I've heard. Is this a particular archaic accent?  More importantly, what is Dickens telling us about Sam Weller by having him speak like this? Are there any significant plot elements in Fantastic Beasts that will be missed if I haven't seen the Harry Potter films? I have read all seven Harry Potter books, and The Cursed Child1, but I've only watched the first two movies.  Do I have to watch all eight movies in order to fully understand the significant plot points found in Fantastic Beasts and Where to Find Them?  Is there anything that I'll miss by not having seen them?    1 Waste of money, that. A proof of the fact that the Fourier transform is not surjective from $\mathcal{L}^1(\mathbb{R})$ to $C_0( \mathbb{R})$ Let $f_n = \mathbb 1_{[-n,n]}$ for all $n \in \mathbb{N}$   Compute explicitly $f_n \star f_1$ for all $n \in \mathbb{N}$.  Show that $f_n \star f_1$ is the Fourier transform of $g_n = \frac{  \sin{(2\pi x)} \sin{(2 \pi nx)}}{\pi ^2 x^2}$  Show that $\| g_n \|_1 \to \infty$  Deduce that the Fourier transform is not surjective from $\mathcal{L}^1(\mathbb{R})$ to $C_0( \mathbb{R})$    Here, $C_0(\mathbb{R})$ is the space of continuous functions $f : \mathbb{R} \to \mathbb{R}$ that tends to $0$ at $-\infty$ and $+\infty$. I managed to compute 1) and proved 2). But I don't know how to prove 3). Moreover, I don't see how can 1), 2) and 3) prove 4). Can anyone help? Using differentiation for computing $\int_{0}^{1}\frac{\arctan(ax)}{x\sqrt{1-x^2}}\,dx$ How can I prove that I can differentiate the integral:  $$ \int_{0}^{1} \frac{\arctan(ax)}{x\sqrt{1-x^2}}\,dx $$  First I have to prove this integral converges. Next I have to prove the integral $$ \int_{0}^{1} f_{a}'(x, a)\,dx $$ converges uniformly.  Then I can differentiate integral with Leibniz's rule.  I tried Weierstrass and Dirichlet's tests. Nothing succeeded.   Thank you for help in advance. Manganese has more unpaired electrons than Iron so why is Iron ferromagnetic Manganese paramagnetic? Manganese has five unpaired electrons, but Iron has four, then why is Iron ferromagnetic and Manganese paramagnetic? What's that property I'm missing? At what point is a creature's toughness calculated? If I have  where I can sacrifice a creature and put X 1/1 token creatures onto the battlefield, where X is the sacrificed creature's toughness.  If I have a creature that is 4/4 and cast  to give it +3/+3 then sacrifice it? Do I get 4 tokens or 7?  Also what if my 4/4 creature was dealt 2 combat damage before I sacrificed it? Do I get 2 or 4 creatures?  Finally, what about counters? If my 4/4 had a +1/+1 do I get 4 or 5 tokens? FontAwesome font not found? UK Visa in an expired Nigerian passport - what to use? I am in Nigeria, my passport will expire in 4 months and I have a document to apply for a UK visiting Visa with that passport number.  Should I use it like that or go for another passport. If I choose to get another passport, how will I use it because of the passport number on the about to expired one in the document I want to use for Visa. Methods of speeding up a huge DELETE FROM  with no clauses Using SQL Server 2005.  I am performing a huge DELETE FROM  with no where clauses.  It's basically equivalent to a TRUNCATE TABLE statement - except I'm not allowed to use TRUNCATE.  The problem is the table is huge - 10 million rows, and it takes over an hour to complete.  Is there any way of making it faster without:   Using Truncate Disabling or dropping indexes?   The t-log is already on a separate disk.  Any suggestions welcome! Equivalent of *Nix 'which' command in PowerShell? How do I ask PowerShell where something is?    For instance, "which notepad" and it returns the directory where the notepad.exe is run from according to the current paths. How to Make A button do more than one action xcode I'm Egyptian and flying to Cairo from Tbilisi, via Istanbul. The first flight Tbilisi-Istanbul is on Atlasjet, then from Istanbul to Cairo I am flying on Egyptair. For that, I have to recheck in at Istanbul to my Egyptair flight  Will I need to pass passport control at Istanbul airport to collect my bags and check in on Egyptair? Will I need a transit visa for that? Or it can be all done through neutral zone? I have a list of hosts in the network providing shares via SAMBA. How can I determine either IP address or the host name of one particular host, e.g. the one with the name “SASAK02”.  The output of smbtree is as follows  WORKGROUP     \\SASAK02                    \\SAURA-PC1                  \\PC-VAN-DAMME What is the reason the log transformation is used with right-skewed distributions? I once heard that      log transformation is the most popular one for right-skewed distributions in linear regression or quantile regression   I would like to know is there any reason underlying this statement? Why is the log transformation suitable for a right-skewed distribution?   How about a left-skewed distribution? Too much space between links in post menu Beamer Tikz-cd Problem
