Sent emails have random sender email address. <p>A family member of mine is responding to my emails from different email addresses which are not hers.</p>
<p>e.g. I sent an email from "[email protected]" to "[email protected]". I received two responses from her, one from "[email protected]", which contains no text, and one from "[email protected]". This email contains the message she wrote.</p>
<p>Till now this happened twice, with two different unkownresponding email addresses.</p>
<p>My grandma is not using different email adresses on purpose. She uses a pc with Windows7 and Outlook. What is a common way to investigate this problem? At which points could the email address be changed? </p>

eigenvalues and eigenvectors for rectangular matrices. <p>We can generalize matrix inverses from non-singular square matrices to rectangular matrices in general, for example, the well-known Moore–Penrose pseudoinverse. I am wondering how this can be done for eigenvalues and eigenvectors. </p>
<p>Though $\det(|A-\lambda I|)=0$ cannot be used any more when $A$ is not square, there is nothing that prevents one to consider $Av=\lambda v$ for non-zero vector $v$ except the possibility of having an inconsistent linear system. </p>
<p>Please give your comments and provide some references if there are some. </p>
<p>Many thanks.</p>
<p><strong>Edit</strong></p>
<p>I know SVD. But it does not seem to be the one I wanted. For SVD of real matrix $A$, $A=UDV^T$ where $U, V$ are orthogonal matrices and $D$ is diagonal (with possibly zeros in the diagonal). We only have $AV_{*k}=\sigma_{k}U_{*k}$, $V_{*k}$ is the $k^\text{th}$ column of $V$. Since $V_{*k}$ and $U_{*k}$ are in general different, it does not resemble $Av=\lambda v$ for non-zero vector $v$ in the definition of eigenvectors. Also, even if we can have $A^TAV_{*k}=\lambda V_{*k}$, but this is for the (square) matrix $A^TA$, rather than $A$ itself.</p>

Why is cross-correlation not defined in a normalized sense?. <p>When correlation is defined in systems and signals, as well as in the statistical sense, it is defined as a normalized measure with respect to the Cauchy-Schwarz inequality.</p>
<p><span class="math-container">$\space$</span></p>
<p>In systems and signals, correlation is defined as</p>
<p><span class="math-container">$$\rho = \frac{ \langle x(t), \space y(t) \rangle}{\| x(t)\|\|y(t)\|} = \frac{1}{\sqrt{E_xE_y}}\int_{-\infty}^{\infty}x(t)y^*(t)dt$$</span></p>
<p>Here, the inner product is normalized by dividing it by the square root of the energies, or the norms, of the two signals in question. The Cauchy-Schwarz inequality for this case is stated as</p>
<p><span class="math-container">$$ |\langle x(t), \space y(t)\rangle| \leq \| x(t)\|\|y(t)\|$$</span></p>
<p><span class="math-container">$\space$</span></p>
<p>In statistics, correlation is defined as</p>
<p><span class="math-container">$$\rho_{xy} = \frac{Cov(X,Y)}{\sigma_x\sigma_y}$$</span></p>
<p>Here, the covariance is normalized by dividing it by the square root of the variances, or the standard deviations, of the two random variables in question. The Cauchy-Schwarz inequality for this case is stated as</p>
<p><span class="math-container">$$|Cov(X,Y)| \leq \sigma_x\sigma_y$$</span></p>
<p><span class="math-container">$\space$</span></p>
<p>So, it seems as if there is a universal trend for defining correlation in a normalized sense. That is until we get to cross-correlation. For some reason cross-correlation is defined as</p>
<p><span class="math-container">$$ \psi(\tau) = \langle x(t), \space y(t-\tau) \rangle = \int_{-\infty}^{\infty} x(t)y^*(t-\tau)dt $$</span></p>
<p>Here, the cross-correlation is simply the time-shifted inner product. No normalization has been applied in this definition.</p>
<p><span class="math-container">$\space$</span></p>
<p><strong>So, why</strong> do we define correlation in a normalized sense across the board, but when it comes to its' extended time delayed version, <strong>cross-correlation, we "forget" to normalize it all of a sudden?</strong></p>

Why need useRef to contain mutable variable but not define variable outside the component function?. <p>I have read <a href="https://overreacted.io/a-complete-guide-to-useeffect/#swimming-against-the-tide" rel="noreferrer">A Complete Guide to useEffect - Swimming Against the Tide</a> at Overreacted. </p>
<p>The example shows that if we want to get the latest <code>count</code>, we can use <code>useRef</code> to save the mutable variable, and get it in async function laster: </p>
<pre class="lang-js prettyprint-override"><code>function Example() {
const [count, setCount] = useState(0);
const latestCount = useRef(count);
useEffect(() => {
// Set the mutable latest value
latestCount.current = count;
setTimeout(() => {
// Read the mutable latest value
console.log(`You clicked ${latestCount.current} times`);
}, 3000);
});
// ...
}
</code></pre>
<p>However, I can do the same thing by creating a variable outside the component function, such as:</p>
<pre class="lang-js prettyprint-override"><code>import React, { useState, useEffect, useRef } from 'react';
// defined a variable outside function component
let countCache = 0;
function Counter() {
const [count, setCount] = useState(0);
countCache = count; // set default value
useEffect(() => {
setTimeout(() => {
// We can get the latest count here
console.log(`You clicked ${countCache} times (countCache)`);
}, 3000);
});
// ...
}
export default Counter;
</code></pre>
<p>Are both ways practical, or is there anything bad if I define the variable outside function component?</p>

Bash expansion of ${@} as command. <p>I have a parent script </p>
<pre><code>while read cmd
do
nohup ./script ${cmd[@]} &>> log &
done < ~/list
</code></pre>
<p>that executes this child script </p>
<pre><code>while true
do
eval "${CMD[@]}"
#${CMD[@]}
#./panic
done
</code></pre>
<p>with this list of commands</p>
<pre><code>node ~/www/splash/app.js
node ~/www/splash-two/app.js
</code></pre>
<p>When the child script calls <code>eval ${CMD[@]}</code> it executes the way I expect running that command with no complaints but when I try to remove the eval and run the command using <code>${CMD[@]}</code> it throws the error: </p>
<pre><code>Error: Cannot find module '/home/rumplefraggle/SYS/RABBOT/~/www/splash/app.js'
</code></pre>
<p>Now I thought possibly this had something to do with the node command so I tried to execute
<BR>
<code>ls ~</code>
<BR>
as the command and it throws the error that <code>~</code> can not be found.</p>
<p>Echoing <code>${@}</code> and not running it expands as I would expect it to.</p>
<p>Also manually inserting the command into the child script also works as expected </p>
<p>I don't understand why <code>eval</code> works and simply running the command using <code>${@}</code> does not. What is causing <code>${@}</code> to not expand the <code>~</code>?</p>
<p>Why is node appending the directory name to the command when <code>${@}</code> is used?</p>

Pentagonal tiling. <p>I am currently working on a research project in my last year of high school. For this paper we are discussing Eschers tesselations, both in the euclidian and the non-euclidian plane. At the moment I am focussing on an article about pentagonal tilings in the euclidian plane, since this project is mainly focussed on math I am trying to give a decent proof of why these pentagons can tile the plane. I have been trying to read Karl Reinhardt's paper but since its in german and its written in 1916, I am a little lost.</p>
<p>I have discussed this with both my partners and my teachers but we can't seem to find any decent proof. Could you give me a hand? Maybe you know some papers which discuss the subject?</p>
<p>Your help is very welcome!</p>
<p>Thank you,</p>

There are two observables <strong>A</strong>, <strong>B</strong>. Observable <strong>A</strong> depends on a value emitted by <strong>B</strong>. (Therefore A needs to observe B).

Incorrectly created file in /etc/sudoers.d file with visudo, but broke things. <p>I tried to do what I thought the comments in /etc/sudoers was telling me:</p>
<pre><code># This file MUST be edited with the 'visudo' command as root.
#
# Please consider adding local content in /etc/sudoers.d/ instead of
# directly modifying this file.

<p>Then:</p>

visudo - safely edit the sudoers file
usage: visudo [-chqsV] [-f sudoers] [-x file]

<p>But I didn't read the bit after that more carefully, so I typed:</p>

<p>Instead of</p>
<pre><code>sudo visudo -f /etc/sudoers.d/dci

Why can't my RaspberryPi execute these basic commands as pi?. <p>As it says in the title, my RaspberryPi can't execute some basic commands (e.g. ls, mkdir, su, ...) with the user 'pi'. I always get the following as output:</p>
<pre><code>-bash: /home/pi/bin/ls: Cannot execute binary file: Exec format error
</code></pre>
<p>If I sudo these commands or execute them on any other account, even an account who can't even sudo, it works fine, and it already worked fine at my last login (OK, about 2 weeks ago...) and I didn't install any new software (I read that's often causing this problem), I only used an already-good-known-software which uses the YouTube-API to upload a video. I tried to fix the issue via reboot (it doesn't work often, but sometimes it helps :D). I read about a modified $PATH-Variable, and I think this could be true, but I am not the biggest pro and can't proof it, so here is the output:</p>
<pre><code>echo $PATH
/home/pi/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/games:/usr/games
</code></pre>
<p>As I already said, I think this could really be the reason (that's really confusing, I didn't even know there are such folders), but even if it was, I wouldn't know what to change it to, so I thougt you could say me it's something different or how I have to set the $PATH-Variable. And, maybe, how this could have changed, I didn't do that manually.</p>
<p>I hope someone can help me.
Thanks in advance,
a Noob</p>
<p>EDIT:
I solved the problem in some ways with the marked answer. I just deleted the /home/pi/bin folder (<code>/bin/rm /home/pi/bin</code> to use the <code>rm</code> in <code>/bin/</code>) and logged out (<code>exit</code>) and in to run ~/.profile again. And I was also able to reconstruct how I got these files in there: A few days before I canceled my server, so I used my RasPi to backUp the files for future. I created a folder named <code>oldServer</code>, but forot to <code>cd</code> in it and just <code>get</code>ed the files via SFTP, so they came into /home/pi/, also the folder <code>bin</code>. So at every login, ~/.profile was thinking it would be a special bin and put it into <code>$PATH</code>. The RasPi wasn't able to execute these binaries in there because they were from Debian too, but not from Raspbian in specific, just Debian8. Thanks for your comments and answers!</p>

The worker does not have internet access at home, yet requires a HP Deskjet (<a href="http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?cc=uk&dlc=en&lc=en&product=357211&" rel="nofollow">6540</a>) installing for use in the office.</p>
<p>The <a href="http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01855252&cc=uk&dlc=en&lc=en&os=219&product=357211&sw_lang=" rel="nofollow">HP website</a> mentions:</p>
<blockquote>
<p>To install the printer driver available in Mac OS X 10.6, simply
connect the USB cable to the printer and to the computer. The print
queue will automatically be created.</p>
</blockquote>
<p>The printer is detected and installed, yet when trying to Print the OS complains that it needs to run Apple Update (I'm assuming to download the required drivers).</p>
<p>I can see the <a href="http://support.apple.com/kb/DL907" rel="nofollow">HP Printer Drivers package for download from Apple Support</a> (at 450mb it's too large for me to get easily).</p>
<p>Is there another way around this? (ie to only download and install the drivers required for the individual Deskjet, not hundreds of others.)</p>

Distance between satellites revolving in different planes. <p>Can satellites moving in orbits that lie in different planes remain at the same distance from each other at all times? How can I prove that they cannot? </p>
<p>Satellites can revolve at different angular velocities. Both orbits have the planet's centre of mass at their centres, so their planes must intersect. </p>

Constructing a diffeomorphism which maps $\Gamma$ to a parabola. <p>$f : \mathbb{R} \to \mathbb{R}$ be a differentiable function and
$$\Gamma = \left \{ (x,y) \in \mathbb{R}^2 | y=f(x) \right \} \subset \mathbb{R}^2$$ its function graph.</p>
<p>a.) Construct a diffeomorphism $\varphi : \mathbb{R}^2 \to \mathbb{R}^2$, which maps $\Gamma$ to the parabola with the equation $y = x^2$.</p>
<p>b.) Show that there is no diffeomorphism $\varphi: \mathbb{R}^2 \to \mathbb{R^2}$ which maps $\Gamma$ on the set with the equation $y = \mid x \mid$</p>
<p>I know from the teacher that the solution for a.) is $\varphi(x,y) \to (x, y+x^2)$.
Unfortunately, I don't see how he got to this solution. Can someone explain it to me? I can not imagine how a diffeomorphism can be mapped on a parabola.</p>
<p>And for b.) how do I show that there is no diffeomorphism? Do I have to show that it is not differentiable everywhere?</p>
<p>Thank you very much for your time!</p>

How many incremental backups to keep with Percona xtrabackup?. <p>I'm looking to replace an aging and decidedly suboptimal <code>mysqldump</code>-based database backup strategy with Percona's Xtrabackup. This all looks pretty straightforward, except that I'm wondering: how many incremental backups should I keep between full backups?</p>
<p>I realize that restoring from a long set of incrementals would be somewhat tedious, but it looks like it'd be pretty easy to script.</p>
<p>I also imagine that if I somehow lose an incremental that's part of a backup set, I would lose everything from that point on. That seems like it'd be unlikely (these guys will be headed to S3), but still a bad day.</p>
<p>Are there rules of thumb about this sort of thing? Would hourly incrementals with a complete backup a week (so, 168 files per backup set) be insane, or normal for some workloads?</p>
<p>FWIW, we're looking at a ~10M row database, growing at ~20k rows a day, very few changed rows (ie, append-mostly). So the incrementals would be pretty small.</p>

Can every Banach space with the Schur property embed into $L_{1}(\mu)$ for some $\mu$?. <p>In 1974, W. B. Johnson and E. Odell observed that there are subspaces $X$ of $L_{1}$ with the Schur property. In 1980, J. Bourgain and H. P. Rosenthal constructed a subspace $X$ of $L_{1}$ such that $X$ has the Schur property, but $X$ is not isomorphic to a subspace of $l_{1}$. Hence, I have the first question as follows:</p>
<p>Question 1. Is every Banach space with the Schur property isomorphic to a subspace of $L_{1}(\mu)$ for some measure $\mu$?</p>
<p>Moreover, W. B. Johnson and E. Odell gave natural non-trivial conditions that a subspace of $L_{p}$ embeds into $l_{p}$ for $1<p<\infty, p\neq 2$. But </p>
<p>Question 2. Are there conditions that a subspace of $L_{1}$ embeds into $l_{1}$ ?</p>
<p>Thank you!</p>

Finding other generalized inverses besides the pseudoinverse?. <p>I have a <span class="math-container">$16\times 4$</span> matrix <span class="math-container">$A$</span> of rank <span class="math-container">$4$</span>. Besides its Moore-Penrose pseudoinverse <span class="math-container">$A^+$</span>, I'm also interested in other generalized inverses <span class="math-container">$A^g$</span> that satisfy <span class="math-container">$A^gA=I_4$</span>.</p>
<p>Is there a way to get <em>all</em> of them (presumably in some analytical form with free variables)?</p>
<p>Are there any <em>special</em> inverses? By "special," I mean <span class="math-container">$A^+$</span> gives the solution to <span class="math-container">$Ax=y$</span> with minimum <span class="math-container">$\ell_2$</span> norm, so is there one such <span class="math-container">$A^g$</span> that gives the solution with minimum <span class="math-container">$\ell_0$</span> norm, for example?</p>
<p>If the answers to the two questions above are both "No," how do I find <em>any</em> generalized inverse other than the pseudoinverse? </p>

<p>I'm having trouble replicating these errors and I'm wondering if there is a straightforward way to use valgrind with my package to reproduce these errors. I've tried running locally with valgrind but couldn't get the track origins option to work and make it clear where these errors were in my code. I have also tried using Travis-CI with the following .travis.yml file:</p>
<pre><code>language: r
cache: packages
r_check_args: '--use-valgrind'
addons:
apt:
packages:
- valgrind
r:
- oldrel
- release
- devel
env:

Install Ubuntu dual boot with Windows 7 in a JBOD array. <p>Some weeks ago I decided to try ubuntu on a Virtual Machine, and I really like it! Then, some days ago, I tried to install it on my computer, together with Windows 7. But, now, I have a problem. My computer have 2 HD's (1Tb and 500Gb) in a JBOD array, and then, 2 partitions: 50gb for Windows 7, and the rest to my files. I've created another 30gb partition to install ubuntu, from the free space on my 2° partition, but, since I'm really new to ubuntu and linux, I really don't know what to do. Ubuntu doesn't recognize the Raid, and I already checked <a href="https://help.ubuntu.com/community/FakeRaidHowto" rel="nofollow">this</a>, but, since it's a little old, and I can't loose my files, didn't helped too much, I think.
Some details:
The JBOD is configured on the motherboard controller, and windows is installed just with a special driver, with no programs at all.
RAID Controller vendor is AMD.
This kind of question probably are asked frequently, sorry for that, but I am really new to ubuntu. Also, sorry for my poor english, it isn't my native language.</p>
<p>Thanks in advance for your assistance.</p>

<p>The answer given to me is to use substitution. I have seen the answer, and feel that it is not intuitive. I would not have thought of it.</p>
<p>I was thinking of using some standard formulas to solve this problem, such as the following:</p>
<p>$$\int \frac{1}{a^{2} - x^{2}} dx = \frac{1}{2a}\ln\frac{a + x}{a - x} + C$$</p>
<p>$$\int \frac{1}{x^{2} - a^{2}} dx = \frac{1}{2a}\ln\frac{x - a}{x + a} + C$$</p>

[21/f] My BFF of nine years, [22/f], is treating me poorly now that she has a boyfriend.. So I really hope I don't sound like some sort of butthurt friend, but this is really bothering me!
So pretty much last month was my friends 22nd birthday, let's call her Rachel.
I was asking her for us to hang out on her bday, do something special..
She just looks at me sort of sheepishly and goes, "Well we're (her other friends and bf) going out to a bar in *****, I don't know if you'd want to come.." and then she literally lists like the dumbest reasons why I wouldn't want to come like they made no sense. "I don't know if you'd wanna drive there" type of crap.
I felt completely just flat out insulted, like as if I wasn't good enough to celebrate her birthday with the friends she'd made at college (some of whom I've met at least once)
Then again for another friends bday "So John [her bf] can't come to [friend's Bday] so if you wanna come, we can go together."
At this point, her bday was still a couple of days away and she literally made no move to make me feel like I was invited (which I clearly wasn't) and then she goes ahead and wants to use me as some sort of back up for her boyfriend, who she had met roughly 8 months ago.
I was really upset and felt like I must be a really shitty person if my friend of 9 years can treat me like that but then I realized I was just really disappointed in her because what I had expected was for Rachel to say: "Hey, I'm going to be celebrating my birthday and I want you and your boyfriend to come." and instead I got "I'm going out and here's why you wouldn't want to go"
I really need advice on what to do, because either she doesn't care or maybe she doesn't know she's treating me like that.

How do you prove Let φ : R → S be a EPIMORPHISM of rings. Then the image of φ is isomorphic to the factor ring R/ ker φ. <p>Below I have proved this question for a ring homomorphism. </p>
<p>MY QUESTION: How do you prove Let φ : R → S be a EPIMORPHISM of rings. Then the image of φ is isomorphic to the factor ring R/ ker φ </p>
<p>Let φ : R → S be a homomorphism of rings. Then the image of φ is isomorphic to the factor ring R/ ker φ </p>
<p>Proof: </p>
<p>Let I denote the kernel of φ, so I is a two-sided ideal of R. Define a function</p>
<p>φ ̄ : R/I → Imφ by: </p>
<p>φ ̄ (a + I) = φ(a) for a ∈ R. </p>
<ol>
<li><p>φ ̄ is well-defined (i.e. the image of a + I does not depend on a choice of coset representative). Suppose that a + I = a1 + I for some a, a1 ∈ R. Then a−a1 ∈IbyLemma3.3.2. Henceφ(a−a1)=0S =φ(a)−φ(a1). Thus φ(a) = φ(a1 ) as required.</p></li>
<li><p>φ ̄ is a ring homomorphism.
Suppose a + I, b + I are elements of R/I. Then </p>
<p>̄ φ((a +I) +(b +I)) = φ ̄ ((a +b) +I) </p></li>
</ol>
<p>= φ(a+b)</p>
<p>= φ(a) + φ(b)</p>
<p>= φ ̄(a+I)+φ ̄(b+I).</p>
<p>So φ is additive. Also </p>
<p>̄ φ((a+I)(b+I)) = φ ̄(ab+I) = φ(ab)</p>
<p>= φ(a)φ(b)</p>
<p>= φ ̄(a+I)φ ̄(b+I)</p>
<ol start="3">
<li><p>φ ̄ is injective.
Suppose a+I ∈ kerφ. Thenφ(a+I) = 0S soφ(a) = 0S. This means a ∈ ker φ, so a ∈ I. Then a + I = I = 0R + I, a + I is the zero element of R/I. Thus ker φ ̄ contains only the zero element of R/I</p></li>
<li><p>φ ̄ is surjective.
Let s∈Imφ. Thens=φ(r)for some r∈R. Thus s=φ(r+I)and every element of Imφ is the image under φ ̄ of some coset of I in R. </p></li>
</ol>
<p>Thus φ ̄ : R/ ker φ −→ Imφ is a ring isomorphism, and Imφ is isomorphic to the factor ring R/ ker φ.</p>

Concept - What is the practical application of generic top-level-domains?. So it looks like the current proposal for generic top-level-domains hit a recent roadblock [Article](http://arstechnica.com/business/2013/03/verisign-blasts-icann-for-slow-generic-top-level-domain-name-rollout/). I did some quick research on it and got into a whole nest of companies, root domain servers, and companies flinging mud at each other.
My central question is - what will the practical application of generic tld's be?
From what I understand, it will allow what amounts to is another dns layer. So you have subdomains (www., movies., play.,), domains (google, bing, apple) and now essentially top-level-domains (.com, .net) up for purchase. It can allow companies more freedom with the naming of their websites and hopefully allow new companies to flourish. Is this a correct understanding of what will be happening? Also, where is the IPv4 addressing coming from (or does it even support it)?

Permission on Database. <p>I have a login user called TestUser created at the server level that is assigned to a read only role, now I need to create a user for the TestUser login on MyDb</p>
<pre><code>USE [MyDB]
GO
CREATE USER [Test] FOR LOGIN [TestUser]
GO
GRANT SELECT TO [Test]
GO
DENY DELETE TO [Test]
GO
DENY INSERT TO [Test]
GO
DENY UPDATE TO [Test]
GO
</code></pre>
<p>everything is good but when I script that Test user created, I don't see in any place the script that I'm giving select and denying insert, delete and update</p>

Biblatex 'alphabetic' style '+' sign in citation key?. <p><br>
I noticed a strange citation key in my document. All citation keys with multiple authors are generated like this for example: <code>[Ber+07]</code><br>
Where does this <code>+</code> sign come from? I setup biblatex like so:</p>
<pre><code>\usepackage[
backend=biber,
maxcitenames=3,
maxbibnames=3,
style=alphabetic,
sorting=nyt]{biblatex}
\DefineBibliographyStrings{ngerman}{
andothers = {{et\,al\adddot}},
}
</code></pre>
<p>Do I have to write my own biblatex style?</p>

How to use Handlebars ternary helper?. <p>Following <a href="https://stackoverflow.com/a/11916194/770127">this answer</a>, I wrote a helper like </p>
<pre><code>module.exports.register = function (Handlebars) {
Handlebars.registerHelper('ternary', function(test, yes, no) {
return test ? yes : no;
});
};
</code></pre>
<p>I'm certain that the helper is loaded and being defined but can't figure out the syntax to use it. I tried using it like </p>
<pre><code><div>{{ternary(true, 'yes', 'no')}}</div>
</code></pre>
<p>but that gives an <a href="https://github.com/assemble/assemble/" rel="nofollow noreferrer">assemble</a> build error</p>
<pre><code>Warning: Parse error on line 10:
...<div>{{ternary(true, 'yes',
----------^
Expecting 'ID', 'DATA', got 'INVALID' Use --force to continue.
</code></pre>
<p>What is the proper syntax to use a helper like that? </p>

How to improve version control on database structure when migrations take long?. <p>I am working with a team of web developers. We are already using Git for version control of our code and it works well. However, while we are changing our code, it is also common to change the database structure, adding / deleting / renaming columns and tables. The normal answer to that is migration files, and we are already using the migration function of laravel.</p>
<p>Soon, we find that some old project takes a long time in running the migration file. This is mainly because the same column was renamed a number of times. Some columns that no longer exists in the latest version are still added and then deleted when running the migration file. </p>
<p>Is there a way to do database version control in a better way? (We are using MySQL)</p>

CGImage of UIImage return NULL. <p>I created a function for splitting an image into multiple images, but when I take take the CGImage of the UIImage, the CGImage returns NULL</p>
<pre><code>NSArray* splitImage(UIImage* image,NSUInteger pieces) {
NSLog(@"width: %f, %zu",image.size.width,CGImageGetWidth(image.CGImage));
NSLog(@"%@",image.CGImage);
returns NULL
NSMutableArray* tempArray = [[NSMutableArray alloc]initWithCapacity:pieces];
CGFloat piecesSize = image.size.height/pieces;
for (NSUInteger i = 0; i < pieces; i++) {
// take in account retina displays
CGRect subFrame = CGRectMake(0,i * piecesSize * image.scale ,image.size.width * image.scale,piecesSize * image.scale);
CGImageRef newImage = CGImageCreateWithImageInRect(image.CGImage,subFrame);
UIImage* finalImage =[UIImage imageWithCGImage:newImage];
CGImageRelease(newImage);
[tempArray addObject:finalImage];
}
NSArray* finalArray = [NSArray arrayWithArray:tempArray];
[tempArray release];
return finalArray;
}
</code></pre>

About to get a $1.5 million check. What should I do?. Throwaway because minor celebrity.
May get a business manager at some point, but I respect this sub as much or more than I would respect one. Seen lots of good stuff here.
So here's the deal. Mid-20s. I've made between $60k and $80k for the last several years. Like most in my industry, I'm self employed, so no guaranteed yearly earnings save what I hustle for. Bought a house two years ago that has appreciated very well, ($170k mortgage) but spent my early career savings on the down payment so don't have much in the ways of savings (~$25k between Roth and secondary investment account) other than the house equity. No CC or student debts.
I'm about to be paid $1.5 million for work. No reason to think this kind of thing will happen again in near future or ever. Nothing to guarantee that my yearly take will change too much for the better in the near future (may break $100k this year, may stay there, may not).
Suggestions? Obviously some serious investing should happen, but should I also pay off my mortgage?
EDIT: Thank you all for the suggestions!!! (Even the guy who suggested I quit my career, go back to school, and "get a real job.")
Unfortunately, yes, this will be marked as income and so taxed heavily. Thank-you u/WiF1 for the calculator. I punched in my state. A bit depressing haha
u/PackerFan80 your advice most closely mirrors what lines I had been thinking along. Thanks!
#Thanks again to ALL!
And PS, no I wasn't cast in a show, though that would be damn cool :) Music business.

A problem about the special case of the Vitali-Caratheodory theorem. <p>Let $X$ be a locally compact Hausdorff space, suppose there exists a $\sigma$-algebra $\mathscr{R}$ in $X$ which contains all Borel sets in $X$, and there exists a positive measure $\mu$ on $\mathscr{R}$
which has the following additional properties:</p>
<p>(a) $\mu(K)<\infty$ for every compact set $K\subset X$.</p>
<p>(b) For every $E\in \mathscr{R}$, we have
$$\mu(E) = \inf\, \{\mu(V): E\subset V, V \mathrm{ open}\}$$.</p>
<p>(c) The relation</p>
<p>$$\mu(E) = \sup\,\{\mu(K): K\subset E, K \mathrm{ compact}\}$$</p>
<p>holds for every open set $E$, and for every $E\in \mathscr{R}$ with $\mu(E)<\infty$.</p>
<p>Suppose $f\in L^1(\mu)$, $f$ is real-valued, and $\epsilon>0$. Does there exist functions $u,v:X\to \Bbb R$ on $X$ such that $u\le f\le v$, $u$ is upper semicontinuous and bounded above, $v$ is lower semicontinuous and bounded below, and $\int_X(v-u)\,d\mu<\epsilon$?</p>
<p>[Let $f$ be a real (or extended-real) function on a topological space. If
$$\{x:f(x) >\alpha\}$$
is open for every real $\alpha$, $f$ is said to be lower semicontinuous. If
$$\{x:f(x) < \alpha\}$$
is open for every real $\alpha$, $f$ is said to be upper semicontinuous.]</p>

Turning a Binge into a Win. I ate too many calories the last 3 days... a combination of being intensely stressed at work, finding out my moms cancer returned, stressing about COVID... I just fell off the wagon completely. I ate until I was in pain. I felt myself pushing past the pain to eat more and I couldn't stop... I still tracked everything I ate, because I want to be honest with myself. I'm up 4lbs, but it makes sense with what I've been eating.
I'm going to stick to 1650 calories today and go for a walk. I'm trying to reframe this as practicing getting back on track. I've always let a bad day turn into a bad week, bad month, bad year... Not anymore. This is a lifelong skill I need to build. I wanna turn this binge into progress.
