Two different types of pull ups. During my 1~ish year of bodyweight training and surfing various blogs and sites about calisthenics, gymnastics, and bodyweight training, I realized that there are **two** types of pull ups that different people seem to advocate.
The first is the hollow pull-up. [like this](https://www.youtube.com/watch?v=p2nUfCQi0Vw)
The one where it feels like your shoulder ball is rotated into the socket and your abdominal + lats are rock solid. At the top of the pull up, the shoulder blades are pretty neutral and depressed. Also, you seem to pull your body *around* the bar rather than under it.
The second resembles the gironda pull up. [like this](https://www.youtube.com/watch?v=XB_7En-zf_M)
There is more of a puffed chest, and you pull from under the bar until your chest touches the bar. At the top of the pull up motion, there is a near complete retraction of the scapula. When I do this version, I feel a burn near the low trap/rhomboid area.
All this time, I have been doing the hollow pull up version, and recently I tried doing the second version, where your scapula is completely retracted. It was incredibly difficult, and could only do around 5 with proper form until I would return to doing hollow pull ups.
Is this a bad thing? Which is the correct version? Is the second version worth pursuing? | 0non-cybersec

iOS VoiceOver "Heading not found". <p>I have a UITableView where each UITableViewCell has 2 UILabels: 1 header and 1 content. The AccessibilityTrait of the header is set to "header". I'm able to see the trait set correctly when inspecting the simulator screen with Accessibility Inspector. But on the actual device, when I switch the rotor to "Headings", it only finds the navigation bar header, but does not find the headers in the UITableViewCells.</p>

How to organise a Show layout in React Admin using a Material UI Grid. <p>I've created a number of Show views in a new React-Admin project. Rather than have the fields just form a single column I would like to use Material UI's Grid component to arrange them into a more efficient and helpful layout. Unfortunately this stops React Admin's ...ShowLayout components from rendering the Field components inside them properly.</p>
<p>I was hoping to be able to do something like this:</p>
<pre><code><Show {...props}>
<SimpleShowLayout>
<Grid container>
<Grid item>
<TextField source="firstName" />
</Grid>
<Grid item>
<TextField source="lastName" />
</Grid>
</Grid>
</SimpleShowLayout>
</Show>
</code></pre>
<p>I've also had a go at creating wrapper components to try to ensure the right props get passed along to the Field components, to no avail. How can I better arrange the fields in a layout? Do I have to fall back to "manually" styling the contents of a show layout using custom styles? If so that seems a shame given that RA uses MUI so heavily for rendering and it already provides a framework for doing this.</p>

How can I force VM's to use the machine host proxy settings?. <p>I have various types of VM's running that I'd like to use my local host machine's proxy settings. This way any browser activity from the VM would go through the host proxy even if the VM's proxy settings are turned off. But they seem to ignore the settings and just go straight out to the internet bypassing the proxy. I'd like the same response from smart phone emulators installed on the host. But they ignore the host settings as well. How can they even do that in the first place???</p>

Congruence relationship used for primitive residue classes modulo n result. <p>I'm trying to understand a proof for a theorem that states conditions under which the group of primitive residual classes modulo $n$ is cyclic. This proof uses the following result attributed to Gauß:
$$
(1 + p)^{p^{\nu - 1}} \equiv 1 \pmod {p^\nu},\qquad(1 + p)^{p^{\nu - 1}} \not\equiv 1 \pmod {p^{\nu + 1}},
$$
where $p$ is an odd prime and $\nu \in \mathbb{N}$.</p>
<p>This result is used to derive without further explanation the following incongruence
$$
(1 + p)^{p^{\nu - 2}} \not\equiv 1 \pmod {p^{\nu}}
$$
where $\nu \geq 2$.</p>
<p>Can somebody explain how one can obtain the second incongruence from the first one? It's probably something simple, but I'm just not seeing it at the moment. Thanks.</p>

Had my first night(s) away from my kid since birth and...it. Was. Amazing.. My little is 1.5 yo and we sent her to Gma/Gpa’s farm for the weekend. I didn’t know how badly I needed this time away from her. Being alone with my husband felt like we were young again- not mama and dada with serious responsibilities/obligations. We did nothing special but have loved every minute. Slept in, went for out for every meal (nothing fancy) without planning ahead, took our dog for long walks to the park. Want to take a nap? Why yes I do! Want to get lunch somewhere and not shovel our food in before the toddler time-bomb goes off? Yes please! Let’s get mani/pedis after lunch! Another nap? Ok! The only unfortunate thing is I couldn’t indulge in wine with lunch because I’m pregnant again. Another reason my husband and I really needed this time quality time though. I’m disappointed I waited this long to take a breather from our 1st. It’s easier said than done but we need to do this once a quarter. I felt like myself today- the girl who has few cares in the world and enjoys sitting quietly in the sun well after we’re done eating- just relaxing and talking about nothing of consequence. Can’t wait to spend one more slow morning with coffee in bed before she comes home. I love her with everything I have but I forgot how much I like my life sans kid. I’ve gotta be better to myself and my relationship with my husband. | 0non-cybersec

Selenium C# Webdriver How to detect if element is visible. <p>Is there a way in the latest version of Selenium DotNet Webdriver (2.22.0) to check to see if an element is visible before clicking/interacting with it?</p>
<p>The only way I've found is to try to handle the ElementNotVisible exception that occurs when you try to send keys, or click on it. Unfortunately this only occurs after an attempt to interact with the element has been made. I'm using a recursive function to find elements with a certain value, and some of these elements are only visible in certain scenarios (but their html is still there no matter what, so they can be found).</p>
<p>It's my understanding that the RenderedWebElement class is deprecated as well other variants. So no casting to that.</p>
<p>Thanks.</p>

wpf xaml binding to object created in code behind. <p>Just to start off I am quite new to C# and xaml.</p>
<p>I have watched, checked tutorials, about binding, but most of what I have seen create an object in the xaml. However I want to create the object in the code and then bind to it's properties. Furthermore I will have several objects defined in code later on. In general I want to bind to text boxes.</p>
<p>In general my code looks something like this:</p>
<p><strong>MainWindow.xaml.cs</strong> </p>
<pre><code>public partial class MainWindow : Window
{
MyTestObject myTestObject;
public MainWindow()
{
myTestObject= new MyTestObject ();
this.DataContext = this;
InitializeComponent();
}
}
</code></pre>
<p><strong>MyTestObject .cs</strong> </p>
<pre><code>class MyTestObject : INotifyPropertyChanged
{
public MyTestObject ()
{
}
private string testString = "Test";
public string TestString
{
get { return testString; }
set
{
if (value == testString) return;
testString = value;
this.OnPropertyChanged("TestString");
}
}
public event PropertyChangedEventHandler PropertyChanged;
protected void OnPropertyChanged(string propertyName)
{
if (PropertyChanged != null)
this.PropertyChanged(this, new System.ComponentModel.PropertyChangedEventArgs(propertyName));
}
}
</code></pre>
<p>Eventually I will have quite a lot of (numerical) properties, which will be displayed in several text boxes, because the software is intended as an interface to an external hardware component that sends measured data. I have tried several ways of binding but I have not succeeded yet. I would be most grateful for an example how to bind the previously mentioned property to a <code>TextBox</code>.</p>

Identity involving zonal polynomials and $\operatorname O(N)$ irrep dimensions. <p><span class="math-container">$\DeclareMathOperator\U{U}\DeclareMathOperator\O{O}$</span>Schur functions <span class="math-container">$s_\lambda(x)$</span> with <span class="math-container">$\lambda\vdash n$</span> are simultaneously the irreducible characters of the unitary group <span class="math-container">$\U(N)$</span> and proportional to Jack polynomials <span class="math-container">$J_\lambda^{\alpha}(x)$</span> with parameter <span class="math-container">$\alpha=1$</span>, <span class="math-container">$J_\lambda^1(x)=\frac{n!}{\chi_\lambda(1)}s_\lambda(x)$</span>, where <span class="math-container">$\chi_\lambda$</span> are the irreducible characters of the permutation group <span class="math-container">$S_n$</span>. As a function of <span class="math-container">$N$</span>, <span class="math-container">$p_\lambda^{\U}(N)=J_\lambda^1(1^N)$</span> is a monic polynomial.</p>
<p>Two important relatives of the Schur functions are the irreducible characters of the orthogonal group <span class="math-container">$\O(N)$</span>, call them <span class="math-container">$o_\lambda(x)$</span>, and the zonal polynomials <span class="math-container">$Z_\lambda(x)$</span>, which are Jack polynomials with parameter <span class="math-container">$\alpha=2$</span>. Both <span class="math-container">$p_\lambda^{\O}(N)=\frac{n!}{\chi_\lambda(1)}o_\lambda(1^N)$</span> and <span class="math-container">$p_\lambda^Z(N)=Z_\lambda(1^N)$</span> are monic polynomials in <span class="math-container">$N$</span>.</p>
<p>I have been led to conjecture the following relation between the reciprocals of these polynomials:
<span class="math-container">$$ \sum_{\lambda \vdash n}\frac{\chi_{2\lambda}(1)G_{\lambda\gamma}}{p_\lambda^Z(N)}=\frac{(2n)!}{2^nn!}\frac{\chi_\gamma(1)}{p_\gamma^{\O}(N)},$$</span>
where <span class="math-container">$2\lambda=(2\lambda_1,2\lambda_2,\dotsc)$</span> and
<span class="math-container">$$ G_{\lambda\gamma}=\sum_{\mu\vdash n}C_\mu \omega_\lambda(\mu)\chi_\gamma(\mu).$$</span>
Here <span class="math-container">$C_\mu$</span> is the size of the conjugacy class in <span class="math-container">$S_n$</span> of elements with cycle type <span class="math-container">$\mu$</span>, and <span class="math-container">$\omega_\lambda(\mu)$</span> are zonal spherical functions of <span class="math-container">$S_{2n}$</span> with respect to the hyperoctahedral group.</p>
<p>This conjectured relation appeared in connection with immanants of random elements from <span class="math-container">$\O(N)$</span> (<a href="https://arxiv.org/abs/2002.08112" rel="nofollow noreferrer">Oliveira and Novaes - On the immanants of blocks from random matrices in some unitary ensembles</a>) and also with commutators of random elements from <span class="math-container">$\O(N)$</span> (<a href="https://arxiv.org/abs/2004.09266" rel="nofollow noreferrer">Palheta, Barbosa, and Novaes - Commutators of random matrices from the unitary and orthogonal groups</a>).</p>
<p>It is easy to prove that this relation holds for large <span class="math-container">$N$</span>, but it seems to be true for every finite <span class="math-container">$N$</span>.</p>
<p>Is this relation known? If not, any idea how to prove it? (Something similar holds for the symplectic analogues, but I omit it for simplicity.)</p>

Proof that a random measure with orthogonal increments is a measure. <p>Let me first state what I mean by a random measure with orthogonal increments.</p>
<blockquote>
<p>Definition: A random measure with orthogonal increments $Z$ is a collection $\left(Z(B): B \in \mathcal{B}_{(-\pi,\pi]}\right)$ of zero-mean, complex random variables $Z(B)$ indexed by the Borel sets $\mathcal{B}_{(-\pi,\pi]}$ defined on some probability space $(\Omega,\mathcal{U},P)$ such that for some finite measure $\mu$ on $(-\pi,\pi]$
$$\mathrm{cov}(Z(B_1),Z(B_2))=\mu(B_1\cap B_2) \quad \forall{B_1,B_2}\in \mathcal{B}_{(-\pi,\pi]}$$</p>
</blockquote>
<p>Honestly, I don't think I understand this definition. If $Z$ is a measure then it must be true that $Z(\emptyset) = 0$. How does this follow from the definition above exactly? Do I take $B_1 = B_2 = \emptyset$ and argue that given $\mathrm{cov}(Z(B_1),Z(B_2))=\mu(B_1\cap B_2) = 0$ and $E[Z(B)] = 0$ for any $B \in \mathcal{B}_{(-\pi,\pi]}$, $Z(\emptyset) = 0$ $\ P$-almost surely?</p>
<p>Next I would like to show that $Z(\cup_j B_j) = \sum_jZ(B_j)$ in mean square whenever $B_1,B_2,\ldots$ is a sequence of pairwise disjoint Borel sets. I am not sure what the mathematical formulation of this result is. My guess is
$$E[\lvert Z(\bigcup_j B_j) - \sum_jZ(B_j)\rvert^2] = 0$$
as this would imply $Z(\cup_j B_j) = \sum_jZ(B_j)$ $\ P$-almost surely, which I think is the most you can expect from a <em>random</em> measure. (If it were an ordinary measure, we would insist on algebraic equality.)</p>
<p>Assuming that my guess is right I proceed. From the definition I have (after a few steps)
$$\mathrm{var}\left(Z\left(\bigcup_j B_j\right)\right) = \mathrm{var}\left(\sum_jZ(B_j)\right) $$</p>
<p>I don't know how to continue from this point on. I would really appreciate some help. Thanks.</p>

Expressing $\sum_{n=0}^{\infty} (\frac{z}{1+z})^n$ as a power series. <p>I'm basically given the following task:</p>
<blockquote>
<p>Express the series:</p>
<p><span class="math-container">$$\sum_{n=0}^{\infty} \left(\frac{z}{1+z}\right)^n$$</span></p>
<p>as a power series for all <span class="math-container">$z \in \mathbb{C}$</span> where the series converges.</p>
</blockquote>
<p>So, I know I need to get the above series in the form <span class="math-container">$$\sum_{n=0}^{\infty} a_n(z)^n$$</span> where the <span class="math-container">$a_n$</span> are constants.</p>
<p>I've tried my best to algebraically manipulate the summand to no success! I know that <span class="math-container">$$\frac{z}{1+z} = \frac{1}{1+\frac{1}{z}} = \frac{1}{1-(-\frac{1}{z})} = \sum_{j=0}^{\infty} (-1)^j\left(\frac{1}{z}\right)^j$$</span></p>
<p>but plugging any of these into the summand of the given series only seems to make things worse!</p>
<p>I've tried to expand out the original series:</p>
<p><span class="math-container">$$\sum_{n=o}^{\infty} \left(\frac{z}{1+z}\right)^n = 1 + \frac{z}{1+z} + \frac{z^2}{(1+z)^2} + \ldots $$</span></p>
<p>but I don't see a pattern.</p>

</code></pre>
<p>I'm assuming this won't brake anything? </p>
<p><code>apt-get -s dist-upgrade</code> (even with <code>sudo</code>), as proposed by @muru, yielded nothing new, except the same old message that <code>appstream</code> has been kept back.</p>

Native iOS/android application to Windows Phone. <p>I have an iPhone application (with an android counterpart), developed in Xcode and written in Objective-C. It is a classical native iOS app, already working and uploaded in the App Store. Similarly, the android version is built with Java and linked with the android SDKs. It's uploaded to the market place.</p>
<p>I was asked to port the app to Windows Phone. Is this possible without modifying the code?
I am not familiar with Windows Phone dev, however it looks like that is a completely
separate ecosystem for developing apps (different programming language, different IDE, different app store etc).</p>
<p>Can I go from Android to Windows Phone or from iOS to Windows Phone? </p>
<p>PhoneGap - or similar platforms - are not options since the code is already written in Objective-C and Java. </p>

Got dad joked at Guitar Center and it was beautiful!. So i made a pit stop at ol' GC to kill off a gift card from Xmas.
I needed one of those little plastic egg shakers (musicians will know) and some drum sticks. The two gentlemen were very rad & we stood around shootin' the shit for a bit.
Then the one who had my plastic shaker in his hand went to exhibit its shaker-y-ness only for it to fly out of his hands (on accident of course) and nail me in the chest.
The other gentleman responded with "That's not what he meant by drum throne!"

Swift - Directions to Selected Annotation from Current Location in Maps. <p>My app currently has a local search which adds annotations for the search results. I want to set it up where when you select the annotation and click the call out button, it will open in the Maps application with directions to the annotation from the current device location. I'm having a few problems with this.</p>
<p>First of all, my call out button on the annotation does not appear. Secondly, I don't think I am detecting the selected annotation correctly.</p>
<p>Here is my code for the search and selected annotation:</p>
<pre><code>func performSearch() {
matchingItems.removeAll()
let request = MKLocalSearchRequest()
request.naturalLanguageQuery = searchText.text
request.region = mapView.region
let search = MKLocalSearch(request: request)
search.startWithCompletionHandler({(response:
MKLocalSearchResponse!,
error: NSError!) in
if error != nil {
println("Error occured in search: \(error.localizedDescription)")
} else if response.mapItems.count == 0 {
println("No matches found")
} else {
println("Matches found")
for item in response.mapItems as! [MKMapItem] {
println("Name = \(item.name)")
println("Phone = \(item.phoneNumber)")
self.matchingItems.append(item as MKMapItem)
println("Matching items = \(self.matchingItems.count)")
var annotation = MKPointAnnotation()
var coordinates = annotation.coordinate
annotation.coordinate = item.placemark.coordinate
annotation.title = item.name
self.mapView.addAnnotation(annotation)
}
}
})
}
func mapView(mapView: MKMapView!, annotationView view: MKAnnotationView!,
calloutAccessoryControlTapped control: UIControl!) {
if self.mapView.selectedAnnotations?.count > 0 {
if let selectedLoc = self.mapView.selectedAnnotations[0] as? MKAnnotation {
println("Annotation has been selected")
let currentLoc = MKMapItem.mapItemForCurrentLocation()
let mapItems = NSArray(objects: selectedLoc, currentLoc)
let launchOptions = [MKLaunchOptionsDirectionsModeKey: MKLaunchOptionsDirectionsModeDriving]

Proving convexity of a function in $R^2$ with parameters. <p>The question I am posting today relates to convexity analysis of a function. Specifically, proving that a function is convex in $\mathbb{R}^2$ definition. Namely, that a function f, is convex if for all $t \in [0,1]$ and $a,b \in \mathbb{R}^2$, if $f((1-t)a+tb)\leq (1-t)f(a)+tf(b)$.</p>
<p>I have the following function: \begin{equation}
x^2+2xy+y^2+\beta x+\beta y
\end{equation}
where $\beta$ is a parameter value. </p>
<p>Now, I've done the leg work (correctly I believe) to simplify the two components of the definition properly.</p>
<p>Namely, if $f((1-t)a+tb)$ is (1) and $(1-t)f(a)+tf(b)$ is (2) then I've got the following equations:
(1) \begin{equation}
=\beta((1-t)(a_1+a_2)+t(b_1+b_2))+(1-t)^2(a_1^2+a_2^2)+t^2(b_1^2+b_2^2)+
\\(2t-2t^2)(a_1b_1+a_2b_2)
\end{equation}</p>
<p>(2) \begin{equation}
=\beta((1-t)(a_1+a_2)+t(b_1+b_2))+(1-t)(a_1^2+a_2^2)+t(b_1^2+b_2^2)+\\
2((1-t)(a_1a_2)+t(b_1b_2))
\end{equation}</p>
<p>Now, in terms of proving that (1) $\leq$ (2), I think my strategy has been corect. I've shown that the first term of (1) and (2) are the same, and that then second term of (1) $\leq$ (2) because the $(1-t)^2$ and (t^2) mean that for t $\in$ (0,1) that number will be less than (1-t) and t respectively. </p>
<p>It's also true that the second terms of (1) and (2) are equal when t=0 or t=1.</p>
<p>However my problem is the third term. I can't reduce that third term down such that \begin{equation}(2t-2t^2)(a_1b_1+a_2b_2)\leq2((1-t)(a_1a_2)+t(b_1b_2))\end{equation}</p>
<p>This is a problem because I'm sure it means I haven't proven (1)$\leq$(2). I wrote a program in matlab to check if that third term would in practice be problematic and it was for $(a_1,b_1)<0$ or $(a_2,b_2)<0$. Any exceptions defy the definition of convexity so there's got to be some mistake that I've made but I can't seem to find it.</p>
<p>I would really appreciate some advice about moving forward here in terms of the proof. Either there's some mistake in my algebra, or in the way I've interpreted how to do this proof or some next step I can use to show that (1)$\leq$(2).</p>
<p>Thank you all in advance.</p>
<p>Note: I have tried to show the convexity with a Hessian matrix but I'm not sure that's allowed in terms of the specific requirement to show convexity in $\mathbb{R}^2$</p>

How do I apply a manifest from a Puppet Master server to a Puppet Agent node server?. <p>I installed Puppet Agent on a CentOS 7 server. I installed Puppet Master on a different CentOS 7 server. I'm using the free version of Puppet on both servers. The Puppet Agent server requested a certificate. I signed it on the Puppet Master server. There is no software firewall on either server. There is no firewall between the servers. I temporarily enabled port 8140 with SSHD. I used SSH to verify port 8140 was open. I then reverted SSHD to only listen on port 22. Port 8140 wasn't blocked. nslookup on the IP addresses and ping against the domain names shows that both servers have correct networking information about the other server. These are new servers. Puppet has never worked on them before. I created a simple manifest. I applied it to the Puppet Master server locally. It worked without errors. I then tried to apply it to the Puppet Agent server. It didn't work.</p>
<p>From the Puppet Master server, I ran this:</p>
<p>puppet agent neat.pp --server hostNameOfPuppetAgentServer --verbose</p>
<p>There were no errors on the Puppet Master server after I pressed enter. There was no output at all. This produced no logs on the Puppet Agent server. There was no evidence it worked on the Puppet Agent server. I checked, and the effects were not performed.</p>
<p>On the Puppet Master server I ran this:</p>
<p>puppet agent --server hostNameOfPuppetAgentServer --test</p>
<p>The results included "Connection refused -- connect (2)." What is wrong? I expect the manifest to work on a Puppet Agent node.</p>

Is there a free way to monitor a serial port on Windows 7 x64?. <p>I've looked around quite a bit, but I have yet to find a free way to monitor a serial port (without opening or blocking it from other applications), that works on Windows 7 64-bit.</p>
<p>Even Microsoft's own Portmon does not work. A few posts have talked about running it in compatibility mode, but it doesn't work for me. I've tried compatibility mode for Windows XP service pack 2 and 3 (the only ones available on the drop-down list), and neither allow it to function.</p>
<p>So yeah, is there any way of monitoring a serial port for Windows 7 64-bit?</p>

Nesting My Own Frameworks with Carthage. <p>I'm having problems trying to realize the following dependency setup between two frameworks and an app, all developed by me:</p>
<p><a href="https://i.stack.imgur.com/Mg4MT.png" rel="noreferrer"><img src="https://i.stack.imgur.com/Mg4MT.png" alt="enter image description here"></a></p>
<ol>
<li><p><strong>Util</strong> containts a bunch of low-level utilities and extensions to <code>Foundation</code> types such as <code>String</code>, <code>Date</code>, etc.</p></li>
<li><p><strong>UI</strong> contains a bunch of custom <code>UIView</code> and <code>UIViewController</code> subclasses, class extensions for <code>UIColor</code>, <code>UIImage</code>, etc..</p></li>
</ol>
<p>The app and each framework has its own repository on GitHub.</p>
<hr>
<p>The <strong>UI</strong> framework is set up to depend on the <strong>Util</strong> framework, using Carthage:</p>
<ol>
<li><p>The project's <strong>Cartfile</strong> contains a reference to the <strong>Util</strong> repo:</p>
<p><code>github "MyOrganization/Util.git"</code></p></li>
<li><p>Util is listed in "Linked Frameworks and Libraries", but <strong>not embedded</strong> (because <strong>UI</strong> is a <em>framework</em> project, <em>not an app</em>).</p></li>
<li><p>The <em>Framework Search Paths</em> build setting contains <code>$(PROJECT_DIR)/Carthage/Build/iOS</code> in addition to <code>$(inherited)</code></p></li>
<li><p>The .gitignore file is configured to ignore the whole <code>Carthage</code> directory (not just <code>/Build</code>)</p></li>
<li><p>I am <strong>not</strong> using git submodules, and I don't intend to (I have enough headaches already).</p></li>
</ol>
<hr>
<p>If I clone the UI framework and run <code>carthage update</code>, Carthage fetches/builds Util and I can embed it manually to build the UI framework. </p>
<p><em><strong>So far so good.</strong></em></p>
<hr>
<p>But if I clone the <strong>App</strong> framework and run <code>carthage update</code>, Carthage fetches the <strong>UI</strong> repo, but it fails to build:</p>
<ol>
<li><p>The directory <code>App/Carthage/Checkouts</code> contains the checked-out copy of the UI project, as expected. However, there is no further Carthage directory for the nested framework (I assume it should be <code>App/Carthage/Checkouts/UI/Carhage/Checkout/Util</code>).</p></li>
<li><p>Navigating to <code>App/Carthage/Checkouts/UI</code> opening the workspace there with Xcode and building it also fails, obviously. The reference to <code>Util.framework</code> is broken. </p></li>
</ol>
<p>From what I've read, Carthage should fetch the recursive dependency; What am I missing here?</p>
<p>I tried adding both framework URLs the the <strong>App</strong> Cartfile, but xcode still fails to build the <strong>UI</strong> framework. </p>
<p>The bottom part of the log pointed to by the carthage output says:</p>
<pre><code>/Users/me/Projects/App/code/App/Carthage/Checkouts/UI/code/UI/UI/MyClass.swift:10:8: error: no such module 'Util'
import Util
^
** ARCHIVE FAILED **
The following build commands failed:
CompileSwift normal arm64
CompileSwiftSources normal arm64 com.apple.xcode.tools.swift.compiler
(2 failures)
</code></pre>
<hr>
<h3>Update</h3>
<p>I put together a <a href="http://nicolas-miari/NestedFrameworkDemo-A" rel="noreferrer">minimal reproducible example</a> on GitHub. The app and frameworks make up this dependency graph:</p>
<pre><code>A -> B -> C
// (and also A -> C, but that's not relevant now)
</code></pre>
<p>(C is the app, B and C are frameworks).</p>
<p>When running <code>carthage update</code> on the <strong>A</strong> project, it fetches both framework repos, checks out both, starts to build <strong>B</strong> first and fails, just as above (<code>import</code> directive).</p>
<p>The checked out copy of <strong>B</strong> has the right Cartfile, along with all the source files, but there is no nested <code>Carthage/</code> directory, let alone the necessary copy of <strong>C</strong> within it. </p>
<p>I guess I need to somehow make the build process refer to <code>A/Carthage/Builds/C.framework</code> instead of <code>A/Carthage/Checkouts/B/Carthage/Builds/C.framework</code>, but don't know how to set up the B project for that to work out... </p>

How to get Outlook 2013 to encrypt using AES and not 3DES. <p>In my company we are exchanging emails with a government authority once a month and they require us to encrypt those emails with encryption algorithm <strong>AES-128, AES-192 or AES-256</strong>. For the purpose we did purchase an <strong>email digital id</strong> from <a href="https://ssl.trustwave.com/email-digital-id" rel="nofollow noreferrer">Trustwave</a></p>
<p>The computer from which we are sending the emails is running <strong>Windows 7</strong> and using <strong>Outlook 2013</strong> as email client.</p>
<p>The authority sent us their certificates and I did install them and attached them to their contact in Outlook. Then I did import our newly purchased certificate in Outlook from <strong>Options > Trust Center > Email Security</strong>
and setup the required algorithm (AES-128).</p>
<p>All looks fine and now we try to send email to the authority but the email explicitly gets encrypted with <strong>3DES</strong> algorithm ...</p>
<p>Then I send encrypted email with the same settings to my colleague and the email is encrypted with the right algorithm - AES-128 ...</p>
<p>I am not able to solve this problem in the last two weeks, I tried multiple times to reinstall all the certificates, to setup all possible different settings related to email encryption in Outlook, tried using <a href="https://www.ritlabs.com/en/products/thebat/" rel="nofollow noreferrer">The Bat</a> email client but nothing solves the problem. <strong>Emails get explicitly encrypted with 3DES</strong> and the authority is not accepting our emails ...</p>

<pre><code>=SUMIFS('A1'!E:E,'A1'!A:A,Dashboard!L8,'A1'!D:D,Dashboard!M6)
</code></pre>
<p>I've looked around in several forums and have found some similar questions but I'm having difficulty deciphering the formulas and applying for my specific need. I think I need to use an <code>INDIRECT</code> formula but can't figure it out.</p>
<p>Any help would be greatly appreciated.</p>

How to use spot instance with amazon elastic beanstalk?. <p>I have one infra that use amazon elastic beanstalk to deploy my application.
I need to scale my app adding some spot instances that EB do not support.</p>
<p>So I create a second autoscaling from a launch configuration with spot instances.
The autoscaling use the same load balancer created by beanstalk.</p>
<p>To up instances with the last version of my app, I copy the user data from the original launch configuration (created with beanstalk) to the launch configuration with spot instances (created by me).</p>
<p>This work fine, but:</p>
<ol>
<li><p>how to update spot instances that have come up from the second autoscaling when the beanstalk update instances managed by him with a new version of the app?</p>
</li>
<li><p>is there another way so easy as, and elegant, to use spot instances and enjoy the benefits of beanstalk?</p>
</li>
</ol>
<p><strong>UPDATE</strong></p>
<p>Elastic Beanstalk add support to spot instance since 2019... see:

Vector space question with linear forms. <p>If I have vector space of $n$ degree polynomials with real coefficients and $f(0) = 0$ and $f(1) = 0$, and inner product $\langle f,g \rangle = \int_0^1 f'(x) g'(x) dx$, how do I show that there is unique $f$ such that $-\int_0^1 f''(x)g(x)dx = g(1/2)$ for all $g \in V$?</p>
<p>For the left hand side, if I apply integration by parts, I get $-\int_0^1 f''(x)g(x)dx=\int_0^1 f'(x)g'(x)dx$ and if I integrate by parts again, I get the expression $\int_0^1 f''(x)g(x) - f(x)g''(x) = 0$. The integrand is $\frac{d}{dx} ( f'g - g'f)$ but I dont know if this is on the right track? Do I need a brute force approach and assume $f(x) = a_nx^n + ... a_1 x$ and try to do something with coefficients?</p>

Align subscripts in math mode. <p>Is there an easy way (maybe provided by <code>mathtools</code> that aligns normal subscripts)? </p>
<p>I know that I can do this manually with <code>\vphantom</code>, but I was looking for a better way.</p>
<pre><code>\documentclass{article}
\usepackage{mathtools}
\begin{document}
\noindent Looks pretty bad:
\[
T_\theta T_\theta^{-1} = \begin{pmatrix*}[r]
\cos\theta & -\sin\theta\\
\sin\theta & \cos\theta
\end{pmatrix*}\begin{pmatrix*}[r]
\cos\theta & \sin\theta\\
-\sin\theta & \cos\theta
\end{pmatrix*}
= \begin{pmatrix}1&0\\0&1\end{pmatrix} = I
\]
adjustlimits doesn't work:
\[
\adjustlimits T_\theta T_\theta^{-1} = \begin{pmatrix*}[r]
\cos\theta & -\sin\theta\\
\sin\theta & \cos\theta
\end{pmatrix*}\begin{pmatrix*}[r]
\cos\theta & \sin\theta\\
-\sin\theta & \cos\theta
\end{pmatrix*}
= \begin{pmatrix}1&0\\0&1\end{pmatrix} = I
\]
vphantom does work
\[
T_\theta^{\vphantom{-1}} T_\theta^{-1} = \begin{pmatrix*}[r]
\cos\theta & -\sin\theta\\
\sin\theta & \cos\theta
\end{pmatrix*}\begin{pmatrix*}[r]

Nginx simple redirect of products from old to new category. <p>I'm making redirects of products from old to new category.</p>
<p>I've managed to make it work with following rule:</p>
<pre><code>rewrite ^/old-category/(.*) /new-category/$1;
</code></pre>
<p>But I want to know when should I use "end line" sign $ and what's the difference with it or without it in my case. For example:</p>
<pre><code>rewrite ^/old-category/(.*)$ /new-category/$1;
</code></pre>
<p>Also I want to redirect users if they simply write old category name (without products), should I create a new rule just for category redirect or I can edit the current rule above to work in both cases.</p>
<p>Thank you for your answers in advance.</p>

Webpack loaders vs plugins; what's the difference?. <p>What is the difference between loaders and plugins in webpack? </p>
<p>The <a href="https://webpack.github.io/docs/using-plugins.html">documentation for plugins</a> just says:</p>
<blockquote>
<p>Use plugins to add functionality typically related to bundles in webpack.</p>
</blockquote>
<p>I know that babel uses a loader for jsx/es2015 transforms, but it looks like other common tasks (copy-webpack-plugin, for example) use plugins instead.</p>

Looking for guidance for my father.. My dad is 70 years old, in very good health (but is also 70) and very active.
Recently, my mother passed away from uterine cancer and my father, myself, and my sister have been helping him to pick up the pieces of a relatively precarious financial situation.
We have paid off all debt tied to him, and we are trying to decide what the best course of action for the remaining balance which is currently a little over 35k, he will eventually be getting repaid an additional 40,000--as soon as my brother who borrowed from him sells the properties he rehabbed (long story, brother stretched himself a bit thin on some property flips).
I am by no means a financial expert, and am in fact only getting my own stuff in order myself from my youth of bad spending, however given his age--what is the best way to put his money to work? Given his age, I'm inclined to think just a high interest savings account to get a little back and still remain accessible for emergencies?
It is still worth mentioning he is still working full time and earning a decent income.
​
Any advice would be appreciated, thank you. | 0non-cybersec

<p>Suppose you can obtain information which will tell you, with certainty, whether or not state 1 (S1) will occur. What is the maximum amount you
would be ready to pay to obtain the information about S1? (Using Bayes' Rule)</p>
<p>I already calculated the expected payoffs of each Alternative w/o the perfect information which is E[A1] = $33,000 E[A2] = $29,000 E[A3] = $39,000. </p>
<p>Not really sure how to calculate the expected total payoff with or without the S1 information, or how to determine it's worth? Thank you.</p>

Is there an algorithmic complexity measure that strikes a balance between regularity and randomness of a string?. <p>If my understanding is correct, Kolmogorov complexity would assign the highest value (description length) to a totally random string, such as:</p>
<blockquote>
<p>abewdwflkweoasfksalsfnlka</p>
</blockquote>
<p>the lowest value to a completely regular string, such as:</p>
<blockquote>
<p>aaaaaaaaaaaaaaaaaaaaaaaaa</p>
</blockquote>
<p>and a middle value to: </p>
<blockquote>
<p>abbbceaxxdabbbceaxxdabbb</p>
</blockquote>
<p>But it seems to me that although the 1st string cannot be perfectly described by any string shorter than itself, it can be more less characterized by a random distribution, i.e. its lack of any structure makes it in a sense less complex than the 3rd string. </p>
<p>Is there any information theoretic or algorithmic measure of complexity that would assign low values to the 1st and 2nd strings while assigning a high value to the 3rd string and strings that have long description length, but do display some structure and regularity? </p>

QT 5.3 Mac Full Screen. <p>I'm trying to set my application to full screen and back in Qt 5.3, but I'm running into some issues on Mac. When I use <code>showFullScreen()</code>, it goes into full screen as expected. It uses the standard Mac full screen mode where it opens in a separate desktop/space. However, when I call <code>showNormal()</code> to return from full screen mode, the application window just disappears and I'm left with a gray background. I need to swipe in order to return to the regular desktop where the application is. </p>
<p>Is this a bug in Qt or am I doing something wrong? I'm on OS X 10.9.3.</p>
