didRegisterForRemoteNotificationsWithDeviceToken does not get triggered - Push Notifications not working. <p>I've spent hours now trying to figure out why <code>didRegisterForRemoteNotificationsWithDeviceToken</code> is not being called.
It worked before. I didn't touch it in weeks. Now stopped working.</p>
<p>Here's my setup:</p>
<ol>
<li>Got <code>didRegisterForRemoteNotificationsWithDeviceToken</code> sitting in <code>SceneDelegate</code></li>
<li>Have declared <code>SceneDelegate</code> to be the <code>UNUserNotificationCenterDelegate</code></li>
<li>I'm setting <code>UNUserNotificationCenter.current().delegate = self</code> in <code>func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions)</code></li>
<li>I'm calling <code>UNUserNotificationCenter.current().requestAuthorization { granted, error in...</code> from one of the UIViewControllers in my App, specifically in <code>viewDidLoad</code> of that Controller - I get the Authorization Pop-up and when accepting I get a <code>true</code> back for <code>granted</code></li>
<li>Within <code>UNUserNotificationCenter.current().getNotificationSettings { settings in ...</code> a check for <code>settings.authorizationStatus == .authorized</code> returns <code>true</code></li>
<li>Push Notifications are added as a capability for the App in "Signing & Capabilities" and the entitlement file has been created. I've even already deleted and re-created the entitlement file - just to be sure...</li>
<li>I've made sure to run the app on a real device (both via Xcode as well as via TestFlight) - so the delegate not being called is not related to the App running in the Simulator.</li>
<li>Have checked if <code>didFailToRegisterForRemoteNotificationsWithError</code> gets called instead at least - but it doesn't.</li>
<li>I have tried with a second physical device which I have never used for testing before.</li>
<li>I've even checked the status of the APNS Sandbox here: <a href="https://developer.apple.com/system-status/" rel="nofollow noreferrer">https://developer.apple.com/system-status/</a></li>
<li>The <code>didReceive</code> delegate gets called though if I'm sending a test notification to simulator via terminal command <code>xcrun simctl push...</code> and I'm getting the notification.</li>
<li>Provisioning profile is managed by Xcode and the specified AppID is configured for Push Notifications. Certificates are set up in apple developer account. </li>
</ol>
<p>Here's how I'm requesting Authorization from the user within <code>viewDidLoad</code> of one of my Apps UIViewControlles</p>
<pre class="lang-swift prettyprint-override"><code>UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .badge, .sound]) { granted, error in
DispatchQueue.main.async {
if (granted) {
//self.processInitialAPNSRegistration()
UIApplication.shared.registerForRemoteNotifications()
UserDefaults.standard.set(true, forKey: "pushNotificationsEnabled")
}
print("permission granted?: \(granted)")
}
}
</code></pre>
<p>And here's the <code>didRegisterForRemoteNotificationsWithDeviceToken</code> delegate method sitting inside <code>SceneDelegate</code>. Note: I'm also setting <code>UNUserNotificationCenter.current().delegate = self</code> in <code>scene willConnectTo and declared</code>SceneDelegate<code>to implement the</code>UNUserNotificationCenterDelegate` protocol.</p>
<pre class="lang-swift prettyprint-override"><code>func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
let token = deviceToken.map { String(format:"%02.2hhx", $0) }.joined()
print("didRegisterForRemoteNotificationsWithDeviceToken GOT CALLED - APNS TOKEN IS: \(token)")
self.apiService.setAPNSToken(apnsToken: token, completion: {result in
switch result {
case .success(let resultString):
DispatchQueue.main.async {
UserDefaults.standard.set(token, forKey: "apnsToken")
print(resultString, " TOKEN IS: \(token)")
}
case .failure(let error):
print("AN ERROR OCCURED: \(error.localizedDescription)")
}
})
}
</code></pre>
<p>Whatever I do, <code>didRegisterForRemoteNotificationsWithDeviceToken</code> is not getting triggered. I'm running out of ideas on what is going wrong.</p>
<p>Where is the error? How can I get <code>didRegisterForRemoteNotificationsWithDeviceToken</code> to execute again?</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:

Video problem in refresh rate. <p>thanks for coming.</p>
<p>I've experienced a strange video problem since I installed Ubuntu. I do not know exactly what is happening, but I think, after a deep research that it's a refresh problem.</p>
<p>In every video/film/youtube I watch, or game that I play, the movements looks gross. The FPS is always high (60 or above) but when a fast action happens the video doesn't follow the movement in a normal way, it's as if the FPS drops, but it doesn't!!</p>

GLB should be turn-based, just like the handheld games. GBL was fun when released, but gets boring after awhile when you keep seeing the same meta pokemons over and over again. No point implementing the buddy feature when I know I can never use my buddy to win if it is not one of those high tier mons.
GBL is also turning into a luck based game, much like scissors paper stone where first pokemon in your line up already heavily determine your win or loss. Moreover, the lag sometimes don't register your taps, causing you to lose as opponent's charged moves keep coming at you.
Since every tap need be sent to the server, why can't we make this go battle league turn based, whereby every turn, opponent and player can decide what they want to do, much like the handheld games. This could even reduce the lag and both have a fair chance to think and exercise their move. Other than one fast move and 2 charged moves, Niantic should also consider the feasibility of one stat enhancing" move that can for e.g, make opponents sleep, attacks to miss, etc... This would defintely make the gameplay more fun, varied and sastifying.
Building on my suggestion above, instead of current 3 pokemons, we can line up 6 pokemons. Instead of 5 sets of 5 matches a day, we can have just 5 sets of 2 matches, or 5 sets of 1 match. This would reduce server load, as well as create a more impactful pvp experience. Instead of mindless tapping, the game now encourages more thinking and strategy.
Lastly, thank you Niantic for implementing the buddy feature. But instead of best buddy just increase by 1 stat, can we have like 2 or more stats increase? Buddies with best buddy ribbon should also have this permanent increase.
Thank you! | 0non-cybersec

Surjecting onto inverse limit of a subsystem. <p>Let $(I, \le)$ be a poset and $\{ A_i \}$ a collection of sets indexed by $I$, such that the projections $\varprojlim A_i \to A_i$ are surjective for all $i \in I$. </p>
<blockquote>
<p>Is it true that the natural map $$\varprojlim_{i \in I} A_i \to \varprojlim_{j \in J}
A_j$$ is surjective whenever $J \subseteq I$?</p>
</blockquote>
<p>This feels true: given a coherent sequence $(a_j)_{j \in J}$, I should be able to use surjectivity of all maps $A_i \to A_{i'}$ to "connect the dots" and obtain a suitable preimage sequence $(a_i)_{i \in I}$. Two failed attempts at a proof have been to use Zorn's lemma on the non-empty posets
$$\Sigma = \{ K \subseteq J: \varprojlim_{i \in I} A_i \twoheadrightarrow \varprojlim_{i \in K} A_i \},$$
$$\Sigma' = \{ I \supseteq K \supseteq J: \varprojlim_{i \in K} A_i \twoheadrightarrow \varprojlim_{i \in j} A_i \}.$$
A proof or a counter-example would be appreciated.</p>

How can I @Input a complex object into my AngularDart component?. <p>I am creating a (my first!) AngularDart app. I have a <code>List</code> of objects of a class <code>Procedure</code> in a <code>procedure_list_component.dart</code> component (modeled after the sample ToDo app's list component). This is displayed in a <code>MaterialListComponent</code> and it all works fine.</p>
<p>I am using Dart SDK 2.1.0 and AngularDart ^5.2.0.</p>
<p>Now I want to develop a new component to display the details of the selected <code>Procedure</code>. The selection part works fine. My detail component currently looks like this:</p>
<pre><code>@Component(
selector: 'procedure-item',
templateUrl: '''
<div>
{{procedure.packageName}}.{{procedure.name}}
</div>
''',
directives: [
],
)
class ProcedureItemComponent {
@Input()
Procedure procedure;
}
</code></pre>
<p>The component's usage looks like this:</p>
<pre class="lang-html prettyprint-override"><code><div *ngIf="selectedProcedure != null">
<procedure-item procedure="{{selectedProcedure}}"></procedure-item>
</div>
</code></pre>
<p>However, at run time I receive the error:</p>
<pre><code>EXCEPTION: Type 'String' is not a subtype of expected type 'Procedure'.

<p>This error makes me suspect that passing a complex object between components is not supported, or there is some magic syntax for passing them.</p>
<p>I have tried using just <code>"selectedProcedure"</code> and <code>{{selectedProcedure}}</code> which result in compiler errors. Which then makes me think that complex objects are supported in this case. </p>
<p>Yes, my confusion is real.</p>
<p>Looking through the docs I cannot find any mention of whether or not this is possible. Every example I can find simply sends <code>String</code>s, but never states specifically that only <code>String</code>s are supported.</p>
<p>Is this really not supported? If it is, what am I doing wrong?</p>

Inventory management system. Hi, I am looking for some kind of inventory management system for keeping record network equipent in stock. We periodicly do receive alot of devices, at several locations and do need to keep track on what we have in stock, instead of using internal mailinglists to ask for a specific device/component.
The system should be:
-web-based
-Run on premise
-keep track of inventory on separate locations | 1cybersec

Show uniform convergence of the series of functions $\sum_{n=1}^\infty \frac{x^n \sin(nx)}{n}$. <blockquote>
<p>Show uniform convergence of the series of functions $\sum_{n=1}^\infty
\frac{x^n \sin(nx)}{n}$ on the interval $[-1,1]$</p>
</blockquote>
<p><strong>My attempt</strong>: I showed the series converges uniformly on the interval $[-1/2,1/2]$ using Weierstrass M-test. I also showed the series converges uniformly on the interval $[1/2,1]$ by using Dirichlet's criterium, where I used that $\left|\sum_{k=1}^n \sin(kx)\right| \leq \frac{1}{\sin(x/2)}$</p>
<p>However, I'm stuck at showing it converges uniformly on the interval $[-1,-1/2]$. I tried to apply Dirichlet's criterium but can't conclude anything because of the behaviour of the term $x^n/n$ (which does not decrease monotonically). </p>
<p>Any ideas?</p>

Showing the join of two disjoint projective varieties is a projective variety.. <p>I'm looking at the following proposition in Harris' Algebraic Geometry: a first course:</p>
<blockquote>
<p><strong>Proposition</strong>: Let <span class="math-container">$X,Y\subset\mathbb P^n$</span> be disjoint projective varieties. Then the join <span class="math-container">$J(X,Y)$</span> of <span class="math-container">$X$</span> and <span class="math-container">$Y$</span>, i.e. the union of all lines in <span class="math-container">$\Bbb P^n$</span> which intersect <span class="math-container">$X$</span> and <span class="math-container">$Y$</span>, is a projective variety.</p>
</blockquote>
<p>What I'm having trouble with is determining where the <strong>disjoint</strong> assumption is used. The proof given is as follows (modulo some rewording):</p>
<blockquote>
<p><em>Proof</em>: By [previous example], the locus <span class="math-container">$\mathscr C_1(X)$</span> of lines in <span class="math-container">$\Bbb P^n$</span> that intersect <span class="math-container">$X$</span> is a closed subvariety of the Grassmannian <span class="math-container">$\Bbb G(1,n)$</span>, and similarly <span class="math-container">$\mathscr C_1(Y)$</span> is a closed subvariety of <span class="math-container">$\Bbb G(1,n)$</span>, so their intersection <span class="math-container">$Z:=\mathscr C_1(X)\cap\mathscr C_1(Y)$</span> is closed in <span class="math-container">$\Bbb G(1,n)$</span>. But then by [previous proposition], the union in <span class="math-container">$\Bbb P^n$</span> of all elements of <span class="math-container">$Z$</span> is a closed subvariety of <span class="math-container">$\Bbb P^n$</span>, and this is exactly equal to <span class="math-container">$J(X,Y)$</span>.</p>
</blockquote>

What is Computer Forensics. Hello knowledgeable people of this fin community!
I am soon starting a road to a career in CyberSec.
I will be doing some basic certifications in my country (Cert III networking and then CertIV CyberSec, these are nationally recognised certifications)
But I am wanting to look into specialised areas of interest. (For further education)
Two areas I have come across and am interested in so far are Computer Forensics and Malware analysis.
Trouble is, how do I follow into these fields? Recommendations?
And what other fields do you find interesting and or work in/have worked in?
I just thought this could be an interesting discussion for myself and other people starting out. Thanks so much all of you amazing people! | 1cybersec

<p>TL;DR, I got the following error:</p>
<pre><code>checking whether the C compiler works... no
configure: error: in `/private/tmp/xz-20160817-3709-1qc3b72/xz-5.2.2':
configure: error: C compiler cannot create executables
See `config.log' for more details
</code></pre>
<p>I checked my <code>config.log</code> as suggested, and found this out:</p>
<pre><code>ld: unknown option: -no_weak_imports
clang: error: linker command failed with exit code 1 (use -v to see invocation)
</code></pre>
<p>I'm guessing this was the problem, but in any case, here's the full <code>config.log</code>:</p>

What's the name for this sort of join?. <p>I'm trying to describe a sort of join between two graphs $G$ and $H$ where you delete one edge from each graph (let's call the vertices adjacent to the deleted edges $g_1$, $g_2$, $h_1$ and $h_2$) , and then join the two graphs by adding an edge between $g_1$ and $h_1$, and another between $g_2$ and $h_2$.</p>
<p>Does this join have a special name? I can't seem to find one, although I have a feeling it has one.</p>
<p>Thanks!</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>

Find a line that is perpendicular to a plane that passes through a point. <p>This is a homework question I am having difficulty answering. (It is Calc III, but this problem only concerns vectors).</p>
<blockquote>
<p>(A) Find the parametric equations for the line through the point $P =
(4, -1, 4)$ that is perpendicular to the plane $3x + 1y - 5z = 1$. Use
"$t$" as your variable, $t = 0$ should correspond to $P$, and the velocity
vector of the line should be the same as the normal vector to the
plane found directly from its equation.</p>
<p>(B) At what point $Q$ does this line intersect the $yz$-plane?</p>
</blockquote>
<p>So Here's what I've tried conceptualizing. First we have point $P$, which we can think of as a vector from the origin. We can also create the normal vector from the plane: $n = \langle 3, 1, -5\rangle$. We can pick a point on the plane that satisfies the equation $p_0 = (2,0,1)$. We can now use this information to start forming a triangle we can solve for. One side: $n - p_0 = \langle 1, 1, -6\rangle$. The hypotenuse can be found with $P - p_0 = \langle 2, -1, 3\rangle$. Which leaves us with one remaining side, which will be a vector within the plane which should give us the point in which the line will intersect with the plane, which we can turn into a vector from the origin and add to the unit vector of $n$ to create our equation.</p>
<p>I <em>think</em> finding this remaining side should be how we get all this information, but I don't know if that's right or if that's even the correct approach. Can anyone give me any advice?</p>

Unable to run an asp.net 4.5 app on xsp on Mono 3. <p>I've build Mono 3.0.2 from source (tarball), and built XSP from both the latest tarball and the latest on Github, but I'm unable to run a relatively simple asp.net app using .net 4.5 because it sees 'targetFramework="4.5"' in the web.config as invalid. Building the app, and running a console .net 4.5 app works just fine.</p>
<p>This is the web.config in question:</p>

<p>If I remove the targetFramework elements from the web.config then the error goes away, but I just get a 404, so none of the http modules are getting hooked up.</p>

Script to run Adobe Update Remote Manager as Launch Daemon at Boot without MDM. <p><strong>Scenario</strong>: I need to figure out how to run the <code>/usr/local/bin/RemoteUpdateManager</code> at DeepFreeze maintenance cycle. During this maintenance cycle, the computers will restart to the login screen and enter a thaw and locked mode for a period of time. As mentioned we do not have a MDM yet, so I created a launch daemon which to my understanding should run the script at boot without requiring any input or to login.</p>
<p><strong>Update.sh</strong></p>
<pre><code>#!/bin/bash
rum=/usr/local/bin/RemoteUpdateManager
if [[ -f $rum ]]; then
echo "Starting Adobe RemoteUpdateManger..."
sudo $rum --action=list #Listing the updates for now, but will install later
else
echo "Adobe RemoteUpdateManager not found."
fi
</code></pre>
<p>Based off Adobe's RUM guide, <a href="https://helpx.adobe.com/ca/enterprise/package/help/using-remote-update-manager.html" rel="nofollow noreferrer">link</a>, you have to use sudo for RemoteUpdateManager</p>
<p><strong>com.test.schedule.plist</strong></p>
<pre><code><?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

<key>StandardOutPath</key>
<string>/var/log/EsoUpdate.log</string>
</code></pre>
<p>
</p>
<p><strong>Steps Taken</strong> </p>
<ol>
<li>Copy update.sh to <code>/Library/Scripts/</code> and the .plist to <code>/Library/LaunchDaemons/</code> </li>
<li><code>sudo chown root:wheel</code> .sh</li>
<li><code>sudo chown root:wheel</code> .plist.</li>
<li><code>sudo launchctl load -w /Library/LaunchDaemons/.plist</code></li>
<li>The moment I load the .plist, it creates two logs at <code>/var/log/</code>. The standardoutpath log lists all the updates which is exactly what I want.</li>
</ol>
<p><strong>Issue</strong></p>
<p>After restarting the computer to see if results stick, I notice that the results cannot be replicated. Instead I receive the following in StandardErrorPath log:</p>
<blockquote>
<p>RemoteUpdateManager exiting with Return Code (1)</p>
</blockquote>
<p>Based of the RUM guide, Return Code (1) is: "Generic error, for example an internal error. For example, this might be the case where Adobe Application Manager installation is corrupted or network is not present. In this case, typically, the process of downloading or installing updates cannot be started at all."</p>
<p>I went as far to apply chmod 777 and chown root:wheel to both the .sh and .plist, along with `/usr/local/bin/RemoteUpdateManager'. Tried without sudo in the .plist and .sh. </p>

Pow, RVM and ZSH not working together. <p>I'm trying to get Octopress (http://octopress.org/) working, but I'm having some issues.
I'm using POW (http://pow.cx/) and it seems to not load the correct Ruby version for me (using RVM).</p>
<p>It always uses the RVM default ruby version and not the one specified in .rvmrc. My default Ruby version in RVM is: ruby-1.9.3-p125.</p>
<p>In my .rvmrc file I have this: <code>rvm use 1.9.2</code>
I get this error in the browser when visiting my site:</p>
<pre><code>LoadError: cannot load such file -- bundler/setup

</code></pre>
<p>Why is it using 1.9.3-p125 when 1.9.2 is specified in my .rvmrc file? If I set 1.9.2 as default it works of course...</p>
<p>Isn't it supposed to do this magic for me and use the correct ruby versions?</p>

Numbers in text, without having to update values from external files by hand?. <p>I am writing a paper discussing numerical results of simulations. I am still tuning those simulations itself, so the results keep changing slightly. I don't want to re-type numbers over from what I computed all the time into the LaTeX document by hand.</p>
<p>I am currently using python to extract results and spit it out files in LaTeX format which are then <code>\include</code>'d (<code>tabular</code>s with numbers, basically), but this approach is not very flexible -- in particular, I can't refer to those numbers in running text.</p>
<p>Is there a packaged way to have e.g. text file with <code>name value</code> lines and then refer to <code>value</code> using <code>\name</code> in LaTeX, or something similar?</p>

How to combine possible permutations of two sets to find number of combined permutations. <p>I hope the title accurately describes the question.</p>
<p>I have a question that asks:</p>
<p>There are 7 male swimmers and 5 female swimmers. If there is a gold, silver, and bronze medalist male swimmer, and a gold and silver medalist female swimmer, how many arrangements are possible?</p>
<p>Here's how I approached the problem:</p>
<p>I looked at the male swimmers first,</p>
<p>Gold medal = 7 possibilities
Silver medal = 6 possibilities
Bronze medal = 5 possibilities</p>
<p>7!/4! = 210 possible arrangements for the males</p>
<p>for females:</p>
<p>Gold medal = 5 possibilities
Silver medal = 4 possibilities</p>
<p>5!/3! = 20</p>
<p>Now this is where I got kind of unsure about what to do....</p>
<p>I decided to think of the next step as two task,</p>
<p>task 1 = pick 3 boys, task 2 = pick 2 girls</p>
<p>task 1 = 210 options (number of permutations), task 2 = 20 options</p>
<p>so 210 x 20 = 4200......I think that number seems really high. Is there a proper method to use for this type of question? Or is it just kind of an combination of methods. </p>

Can the name “localhost” in a virtual machine be mapped to IP of host machine?. <p>I have a virtual machine image (using Virtual PC) of Windows XP/IE6 from Microsoft's "modern IE" website. This virtual machine is hosted by a Windows 7 machine.</p>
<p>I have a local web application on the host machine and need to check it in IE6 (sadly). Inside the virtual machine, can the "localhost" name be mapped to point to the IP of the host machine? I tried editing the c:/windows/system32/drivers/etc/hosts file in the virtual machine to [IP address of host machine] localhost but that doesn't work. The reason I want to use "localhost" rather than an IP is because some of the web application's configuration files point to "localhost."</p>
<p>I can change the configuration files to point to a different domain name, but I wanted to know if the "localhost" name itself can point to something else. I get the feeling that "localhost" is some type of reserved keyword that only points to 127.0.0.1.</p>

How to get the Hard Drive serial number. <p>I wanted to get the serial number assigned by Hard disk manufacturer.</p>
<p>The serial number is usually printed in the hard disk. Normally to get the serial number, I have to take out the hard disk.</p>
<p><strong>Is it possible to know the hard drive serial number from command prompt or in other way.</strong></p>
<p>Before posting this question I have gone through this <a href="https://superuser.com/questions/498083/how-to-get-hard-drive-serial-number-from-command-line">question</a> but I am getting the error in the following screenshot:</p>

Aliased network interfaces and isc dhcp server. <p>I have been banging my head on this for a long time now. There are many discussions on the net about this and similar problems, but none of the solutions seems to work for me.</p>
<p>I have a Debian server with two ethernet network interfaces. One of them is connected to internet, while the other is connected to my LAN.</p>
<p>The LAN network is 10.11.100.0 (netmask 255.255.255.0).</p>
<p>We have some custom hardware that use network 10.4.1.0 (netmask 255.255.255.0) and we can't change that. But we need all hosts on 10.11.100.0 to be able to connect to devices on 10.4.1.0. So I added an alias for the LAN network interface so that the Debian server acts as a gateway between 10.11.100.0 and 10.4.1.0.</p>
<p>But then the dhcp server stopped working.</p>
<p>The log says:</p>
<pre><code>No subnet declaration for eth1:0 (no IPv4 addresses).
** Ignoring requests on eth1:0. If this is not what
you want, please write a subnet declaration
in your dhcpd.conf file for the network segment
to which interface eth1:1 is attached. **
No subnet declaration for eth1:1 (no IPv4 addresses).
** Ignoring requests on eth1:1. If this is not what
you want, please write a subnet declaration
in your dhcpd.conf file for the network segment
to which interface eth1:1 is attached. **
</code></pre>
<p>I had another server before, also running Debian but with the older dhcp3 server, and it worked without any problems. I've tried everything I can think of in dhcpd.conf etc, and I've also compared with the working configuration in the old server.</p>
<p>The dhcp server need only handle devices on 10.11.100.0.</p>
<p>Any hints?</p>
<p>Here's all relevant config files:</p>
<p><strong>/etc/default/isc-dhcp-server</strong></p>
<pre><code>INTERFACES="eth1"
</code></pre>
<p><strong>/etc/network/interfaces</strong></p>
<p>(I've left out eth0, that connects to the Internet, since there is no problem with that.)</p>
<pre><code>auto eth1:0
iface eth1:0 inet static
address 10.11.100.202
netmask 255.255.255.0
auto eth1:1

Can I reuse a nonce to retransmit the same packet using ChaCha20-Poly1305?. <p>I understand the "sudden death" implications of reusing a nonce with ChaCha20-poly1305, but I believe this rule doesn't apply if you are transmitting exactly the same packet.</p>
<p>I'm putting together a small radio protocol where packets can be lost and if an ack isn't received the packet is re-transmitted. In this instance the nonce is reused, but I can't see that an attacker has any more useful information than the initial packet. I would presume that the key is still safe. Is this correct or have I missed something obvious?</p>
<p>EDIT:</p>
<p>It is a custom protocol, based on a resource requirement that prevents going with something like 6LoWPAN.</p>
<p>I was not going to use random nonces, but rather sequential nonces, with the top 32 bits of the 96 bit nonce set to the 32 bit node address that the packet comes from. The problem with this is reliably storing the nonce in flash with limited erase / write cycles. Although I have seen implementations save blocks of nonces, rather than every use.</p>
<p>I can gather entropy from concatenating the lowest bit of multiple reads of the signal strength from the radio, but I would guess that sequential nonces are safer to use, if I can guarantee they are sequential.</p>
<p>I was thinking of using a network registration method where the node, on power up, would have a preshared RX encryption key, but no TX encryption key. The node would ask for network registration where a master node (server) would send a new TX key encrypted and authenticated. If correctly received the new node would use the new TX key and the nonce would start again from 0. This would get around the problem of storing the nonce at the expense of a slight delay in network registration. This network is only designed to be local to a single site, all nodes within reception of each other.</p>

Methods to solve $\int_{0}^{\infty} \frac{\cos\left(kx^n\right)}{x^n + a}\:dx$. <p>Spurred on by <a href="https://math.stackexchange.com/questions/3042335/seeking-methods-to-solve-int-0-infty-frace-xnxn-1-dx">this</a> question, I decided to investigate for different functions on the numerator. Here, I went from <span class="math-container">$\exp(..)$</span> to <span class="math-container">$\sin(..) / \cos(..)$</span>. I initially thought I could modify the result from <span class="math-container">$\exp(..)$</span> but got <a href="https://math.stackexchange.com/questions/3045895/solving-re-left-gamman-bi-right">stuck</a>. So I decided on another approach which here is a combination of Feynman's Trick, Laplace Transforms and coupled ODE Systems. I would love for a qualified eye to have a look over to see if what I've done is correct and/or another method (Not using Complex Analysis) to solve.</p>
<p>Here I've included more of my algebra to aid in those who wish to go over. </p>
<p>Consider the following two definite integrals</p>
<p><span class="math-container">\begin{align}
I_{n,a,k} &= \int_{0}^{\infty} \frac{\sin\left(kx^n\right)}{x^n + a}\:dx \\
J_{n,a,k} &= \int_{0}^{\infty} \frac{\cos\left(kx^n\right)}{x^n + a}:dx
\end{align}</span></p>
<p>For <span class="math-container">$a,k \in \mathbb{R}^+$</span> and <span class="math-container">$n \in \mathbb{R}^{+}, n > 1$</span>. Here we define:</p>
<p><span class="math-container">\begin{align}
I_{n,a,k}(t) &= \int_{0}^{\infty} \frac{\sin\left(tkx^n\right)}{x^n + a}:dx \\
J_{n,a,k}(t) &= \int_{0}^{\infty} \frac{\cos\left(tkx^n\right)}{x^n + a}:dx
\end{align}</span></p>
<p>Here we observe that:
<span class="math-container">\begin{align}
I_{n,a,k}(1) &= I_{n,a,k} & I_{n,a,k}(0) &= 0 \\
J_{n,a,k}(1) &= J_{n,a,k} & J_{n,a,k}(0) &= a^{\frac{1}{n} - 1} \frac{\Gamma\left(1 -\frac{1}{n}\right)\Gamma\left(\frac{1}{n} \right)}{n} = \theta_{a,n}
\end{align}</span></p>
<p>Here we will address each integral individually. For <span class="math-container">$I_{n,a,k}$</span> we take the derivative with respect to '<span class="math-container">$t$</span>':</p>
<p><span class="math-container">\begin{align}
I_{n,a,k}'(t) &= \int_{0}^{\infty} \frac{kx^n\cos\left(tkx^n\right)}{x^n + a}\:dx = k\left[\int_{0}^{\infty} \cos\left(tkx^n\right)\:dx - a\int_{0}^{\infty} \frac{\cos\left(tkx^n\right)}{x^n + a}\:dx \right] \\
\frac{1}{k}I_{n,a,k}'(t) &= \frac{1}{k^{\frac{1}{n}}t^{\frac{1}{n}}}\int_{0}^{\infty} \cos\left(u^n\right)\:du - aJ_{n,a,k}(t)
\end{align}</span></p>
<p>Thus, </p>
<p><span class="math-container">\begin{equation}
\frac{1}{k}I_{n,a,k}'(t) + aJ_{n,a,k}(t) = \frac{1}{k^{\frac{1}{n}}t^{\frac{1}{n}}}\int_{0}^{\infty} \cos\left(u^n\right)\:du
\end{equation}</span></p>
<p>From Section X, we arrive at:</p>
<p><span class="math-container">\begin{equation}
\frac{1}{k}I_{n,a,k}'(t) + aJ_{n,a,k}(t) = \frac{\Gamma\left(\frac{1}{n}\right)\cos\left(\frac{\pi}{2n} \right)}{nk^{\frac{1}{n}}t^{\frac{1}{n}}}
\end{equation}</span></p>
<p>Applying the same method to <span class="math-container">$J_{n,a,k}\left(t\right)$</span> we arrive at:</p>
<p><span class="math-container">\begin{equation}
-\frac{1}{k}J_{n,a,k}'(t) + aI_{n,a,k}(t) = \ \frac{\Gamma\left(\frac{1}{n}\right)\sin\left(\frac{\pi}{2n} \right)}{nk^{\frac{1}{n}}t^{\frac{1}{n}}}
\end{equation}</span></p>
<p>And thus, we arrive at the couple ordinary differential equation system:</p>
<p><span class="math-container">\begin{align}
\frac{1}{k}I_{n,a,k}'(t) + aJ_{n,a,k}(t) &= \Psi_{k,n}\cos\left(\frac{\pi}{2n} \right)t^{-\frac{1}{n}}\\
aI_{n,a,k}(t) -\frac{1}{k}J_{n,a,k}'(t) &= \Psi_{k,n}\sin\left(\frac{\pi}{2n} \right)t^{-\frac{1}{n}}
\end{align}</span></p>
<p>Where <span class="math-container">$\Psi_{k,n} = \frac{\Gamma\left(\frac{1}{n}\right)}{n}k^{-\frac{1}{n}}$</span>. Although there are many approaches to solving this system, here I will employ Laplace Transforms:</p>
<p><span class="math-container">\begin{align}
\frac{1}{k}\mathscr{L}\left[I_{n,a,k}'(t)\right] + a\mathscr{L}\left[J_{n,a,k}(t)\right] &= \Psi_{k,n}\cos\left(\frac{\pi}{2n} \right)\mathscr{L}\left[t^{-\frac{1}{n}}\right]\\
a\mathscr{L}\left[I_{n,a,k}(t)\right] -\frac{1}{k}\mathscr{L}\left[J_{n,a,k}'(t)\right] &= \Psi_{k,n}\sin\left(\frac{\pi}{2n} \right)\mathscr{L}\left[t^{-\frac{1}{n}}\right]
\end{align}</span></p>
<p>Which becomes:</p>
<p><span class="math-container">\begin{align}
\frac{s}{k}\bar{I}_{n,a,k}(s) + a\bar{J}_{n,a,k}(s) &= \Psi_{k,n}\cos\left(\frac{\pi}{2n} \right)\kappa(s)\\
a\bar{I}_{n,a,k}(s) -\frac{s}{k}\bar{J}_{n,a,k}(s) &= \Psi_{k,n}\sin\left(\frac{\pi}{2n} \right)\kappa(s) + \frac{1}{k}\theta_{a,n}
\end{align}</span></p>
<p>Where
<span class="math-container">\begin{equation}
\kappa(s) = \mathscr{L}\left[t^{-\frac{1}{n}}\right] = \Gamma\left(1 - \frac{1}{n}\right)s^{1 - \frac{1}{n}}
\end{equation}</span></p>
<p>Solving for <span class="math-container">$\bar{J}_{n,a,k}(s)$</span> we find:</p>
<p><span class="math-container">\begin{align}
\bar{J}_{n,a,k}(s) &= \frac{1}{s^2 + a^2k^2}\left[ak^2 \Psi_{k,n}\cos\left(\frac{\pi}{2n} \right)\kappa(s) -k\Psi_{k,n}\sin\left(\frac{\pi}{2n} \right)s\kappa(s) - s\theta_{a,n}\right] \\
&=ak^2 \Psi_{k,n}\cos\left(\frac{\pi}{2n} \right)\frac{1}{s^2 + a^2k^2}\kappa(s)-k\Psi_{k,n}\frac{s}{s^2 + a^2k^2}\kappa(s)\\
&\qquad- \theta_{a,n}\frac{s}{s^2 + a^2k^2}
\end{align}</span></p>
<p>Taking the Inverse Laplace Transform, we arrive at:</p>
<p><span class="math-container">\begin{align}
&J_{n,a,k}(t) = \mathscr{L}^{-1}\left[ \bar{J}_{n,a,k}(s) \right] = ak^2 \Psi_{k,n}\cos\left(\frac{\pi}{2n} \right)\mathscr{L}^{-1}\left[\frac{1}{s^2 + a^2k^2}\kappa(s)\right]\\
&\qquad-ak\Psi_{k,n}\sin\left(\frac{\pi}{2n} \right)\mathscr{L}^{-1}\left[\frac{s}{s^2 + a^2k^2}\kappa(s)\right]- \theta_{a,n}\mathscr{L}^{-1}\left[\frac{s}{s^2 + a^2k^2}\right] \\

Suspension: if $X$ is $(n-1)$-connected CW, is $SX$ $n$-connected?. <p>If $X$ is $(n-1)$-connected CW complex, is that true that $SX$ is $n$-connected?</p>
<p>I'm trying to understand Freudenthal Suspension Theorem on Hatcher. We define the suspension map:</p>
<p>$\pi_i(X)\simeq \pi_{i+1}(C_+,X) \to \pi_{i+1}(SX,C_-X) \simeq \pi_{i+1}(SX)$ </p>
<p>($SX$ is the suspension of $X$, $C_-X$ is the lower cone)
where the middle map is given by the inclusion and the isomorphisms are given by the exact sequence of pairs.
Using the long exact sequence for the pair $(C_+,X)$ we also see that it is $n$-connected, given that $X$ is $(n-1)$-connected. Using the long exact sequence for the pair $(SX,C_-X)$ we only get $\pi_n(SX,C_-X) \simeq \pi_n(SX)$. Thus if $\pi_n(SX)=0$ given $\pi_{n-1}(X)=0$ we can finally apply the Excision Theorem and conclude.</p>
<p>Thanks!</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>

Check if two vertices of a graph are connected with an MILP constraint. <p>I have a mixed-integer linear program (MILP) that needs to select some edges from a graph according to some metrics.</p>
<p>One constraint that I'd like to enforce is that two given nodes have to be connected (i.e. there must exist a path between them).</p>
<p>looking at the adjacency matrix I know that one can find the shortest path or even all the possible path using some algorithms like breadth first search and even Dijkstra.</p>
<p>My question is: given that I do not want to know the path, can I formulate this ''path existence/connectivity problem'' as a constraint for a MILP problem?</p>
<p>The best idea I had was to compute all the paths connecting the two vertices offline and force the selection of at least one of those. Which would work, but it's something really inelegant.</p>

Creating a link for all files in a directory to home. <p>I am trying to write a small zsh (bash compatible) script to take each file in ~/.oh-my-zsh/links directory and creates a hard link for it in ~. I am not sure how to do this. Would this be correct?</p>
<pre><code>pushd .;
cd ~/.oh-my-zsh/links;
ln * ~/*;
popd;
</code></pre>
<p>Thanks.</p>
