Epidemic spacial diffusion problem.. how to draw a graph of differential system of second order with partial derivative. <p>I'm currently working on how to simulate the diffusion of an epidemic in a population. If we don't consider that the population is moving in space, then the differential system is the following: <a href="https://i.stack.imgur.com/nkMMV.png" rel="nofollow noreferrer">Differential System SIS without spacial diffusion</a>. You'll find the corresponding program below. If we consider that the population (the infected people to be more specific) have an anarchic mobility, the differential system will contain a second order partial derivative in respect to the spacial variable x (the problem is considered in one spacial dimension only) as shows the following picture: <a href="https://i.stack.imgur.com/ERFbB.png" rel="nofollow noreferrer">Differential System SIS with spacial diffusion included</a>. The problem I have is how to implement that second order partial derivative in the program, and how draw the graphs of such a differential system.. (even though there is a spacial variable, the axes remain the same: Population and Time) If you take off the partial derivative, it becomes a simple differential system and the corresponding program I made is the following:</p>
<pre><code>from scipy import arange
from scipy.integrate import odeint
import matplotlib.pyplot as plt
import numpy as np
N0 = 1000000 #Initial population number
I0 = 100 #Initial infected number
PopuIni = [N0,I0]
b=1/3000000 #infection rate β
g=1/20 #cure rate of Infected people ɣ
d=5/1000 #death rate, not related to the epidemic (common between infected and susceptible)
n=4/1000 #birth rate (vertical infection from parents to progeny is not
considered here)
def EpidEvol(N,t):
S,I=N
derS = n*(S+I) + g*I - d*S - b*S*I
derI = b*S*I - d*I - g*I
return [derS,derI]
tmax=157
t=arange(0,tmax,0.1)
N=odeint(EpidEvol,PopuIni,t)
</code></pre>
<p>Thank you for your attention.. I sincerely hope to receive help from you</p>
<p><strong>UPDATE 1:</strong>
I found this website which provides a method of solving partial differential equations, but I genuinely don't know how to implement this in my program..

Characteristic function of standard normal distribution using this method.. <p>Lets have $f(t)$ be this characteristic function.
I am told that $f'(t)=-t \cdot f(t)$ and that this can be proven, I found using partial integration and the dominated convergence theorem. I am aware of these theorems. I unfortunately do not know how to do this. The attempts tried are not of value worth sharing.</p>
<p>$$X:N(0,1)$$
$$f(t)=\int_{-\infty}^{\infty}e^{itx}\frac{1}{2\pi}e^{-\frac{x^2}{2}}dx$$ </p>

Time complexity of counting triangles in planar graphs. <p>Counting triangles in general graphs can be done trivially in $O(n^3)$ time and I think that doing much faster is hard (references welcome). What about planar graphs? The following straightforward procedure shows that it can be done in $O(n\log{n})$ time. My question is two-fold:</p>
<ul>
<li>What is a reference for this procedure?</li>
<li>Can the time be made linear?</li>
</ul>
<p>From the algorithmic proof of Lipton-Tarjan's planar separator theorem we can, in time linear in the size of the graph, find a partition of vertices of the graph into three sets $A,B,S$ such that there are no edges with one endpoint in $A$ and the other in $B$, $S$ has size bounded by $O(\sqrt{n})$ and both $A,B$ have sizes upper bounded by $\frac{2}{3}$ of the number of vertices. Notice that any triangle in the graph either lies entirely inside $A$ or entirely inside $B$ or uses at least one vertex of $S$ with the other two vertices from $A \cup S$ or both from $B \cup S$. Thus it suffices to count the number of triangles in the graph on $S$ and the neighbours of $S$ in $A$ (and similarly for $B$). Notice that $S$ and its $A$-neighbours induce a $k$-outer planar graph (the said graph is a subgraph of a planar graph of diameter $4$). Thus counting the number of triangles in such a graph can be done directly by dynamic programming or by an application of Courcelle's theorem (I know for sure that such a counting version exists in the Logspace world by Elberfeld et al and am guessing that it also exists in the linear time world) since forming an undirected triangle is an $\mathsf{MSO}_1$ property and since a bounded width tree decomposition is easy to obtain from an embedded $k$-outer planar graph.</p>
<p>Thus we have reduced the problem to a pair of problems which are each a constant fraction smaller at the expense of a linear time procedure. </p>
<p>Notice that the procedure can be extended to find the count of the number of instances of any fixed connected graph inside an input graph in $O(n\log{n})$ time.</p>

Server over VPN?. <p>I don't know that much about VPN, so it could be that this is utterly impossible. Here's hoping, though.</p>
<p>I would like to forward a port from my router to a machine connected to the network via VPN. That way, I could run a simple server on my laptop, and it would continue to work at the same address no matter where I am. The trick is that I don't want people connecting to the server to have to join the VPN. It should be completely transparent to the end-user.</p>
<p>If it's not possible with VPN, is there some other technology that would make this possible? Basically just forwarding a port to a remote machine, one without a static IP.</p>

trying to call a method in the where of a linq statment. <p>Below is the code I'm using but it replies with</p>
<blockquote>
<p>Method 'Boolean isUser(System.String)' has no supported translation to SQL.</p>
</blockquote>
<p>Any help? Btw I'm using <strong>linq to SQL</strong> data source</p>
<pre><code>public void dataBind()
{
using (var gp = new GreatPlainsDataContext())
{
var emp = from x in gp.Employees
let k = isUser(x.ID)
where x.ActivtyStatus == 0
&& isUser(x.ID) != false
orderby x.ID
select new
{
ID = x.ID,
Name = x.FirstName + " " + x.MiddleName
};
ListView1.DataSource = emp;
ListView1.DataBind();
}
}
public static bool isUser(string ID)
{
int temp;
bool x = int.TryParse(ID, out temp);
return x;
}
</code></pre>
<p>I found a solution to query the result of the first query as objects but is that good cause I will passing through my data twice.</p>
<hr>
<p>the updated code that worked in the end after using the like as advised by Anders Abel</p>

Open "audio option" window
Select "enable aac"
Turn Soundlink Mini on. It won't connect (disconnect/reconnect repeatedly).
Unselect "enable aac"
Turn Soundlink Mini on. It connect immediately.

functions with positive Laplacian. <p>Information about the class of compactly supported smooth functions $u$ on $Ω\subset R^n$ such that $Δu≥0?$ Do a significant class of such function exist?</p>
<p>NB. This type of function may be useful in the problems of controllability.</p>
<p>In the case $n=1$, we can construct geometrically some functions with the above mentioned conditions.</p>

Pictures after 7 years of working out. I've been lifting for almost 7 years now. I had accumulated more dedication and knowledge as the years passed by of course.
I'm 5'8" and started at about 150 lbs. I'm now just over 190 with the intent of cutting to lose fat and lean up. Never used steroids. I'm sure there are people who have achieved more than me in the same amount of time.
Main point of this is to illustrate the gains/time ratio. Many plateaus along the way
Bench - 225 x 15-20 reps. 275 x 8-9 reps
Squat - 455 lbs max
Deadlift - Not sure, rarely do them. It is lower than my squat though :(

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:

Should an interpolation coincide the original function on the given data points?. <p>Suppose having a model $f(x)=y$ where $f$ is unkown. Moreover, suppose you have some data points for this model i.e. $(x_1,y_1), (x_2,y_2), \dots , (x_n,y_n)$.
If one can find an approximate of $f $ called $\tilde{f}$ using the given data points. </p>
<p>When such aproximation is called interpolation? should the approximation vanish on the given data points in order to be considered as an interpolation ( i.e. $\tilde{f}(x_i)=y_i$ for all $i$) ? Thank you in advance. </p>

Derivative and limit question. <p>Suppose $f$ is differentiable on $[0,\infty)$.
One may write
$$
\frac{f(t)-f(0)}{t-0} = f'(\epsilon)
$$
for $t\in (0,1),\epsilon \in (0,t)$ by the Mean Value Theorem.
I would like to then take the limit as $t\to 0$ (so $\epsilon \to 0$ as well) and say that this equals $f'(0)$.
But I think this would require continuity of the derivative, because we don't know how $\epsilon$ changes.</p>
<p>However, if we just apply the definition of $f$ being differentiable we get
$$
\lim_{t\to 0}\frac{f(t)-f(0)}{t-0} = f'(0)
$$
by definition.</p>
<p>This doesn't feel right to me. I wouldn't think that applying the Mean Value Theorem would lose so much information that I cannot justify the limit anymore.</p>
<p>I there a way to show the limit exists using the Mean Value Theorem like I tried? (Of course using the definition is better, but I just want to know if there is a way to do it with MVT).</p>

Server-side rendering + responsive design + inline styles -> which breakpoint to use?. <p>I have a responsive web application built with ReactJS for which I want one day to support server-side rendering. </p>
<p>According to the viewport size, the application layout/behavior changes. But all these changes can not only be done with plain CSS mediaquery: the JS behavior, and the underlying HTML structure also has to be changed according to the width. </p>
<p>For example I could have:</p>
<p><strong>Under 800px width</strong>:</p>
<pre><code><div class="app">
<div class="menu-mobile">...</div>
<div class="content">...</div>
<div class="mobile-left-menu">...</div>
<div class="footer-mobile">...</div>
</div>
</code></pre>
<p><strong>Above 800px width</strong>:</p>
<pre><code><div class="app">
<div class="menu">...</div>
<div class="main">
<div class="left-menu">...</div>
<div class="content">...</div>
<div class="right-menu">...</div>
</div>
<div class="footer">...</div>
</div>
</code></pre>
<p>Now, I want to use server-side rendering for that application. But on the server I don't have the width, so I don't know which HTML structure to return to the client.</p>
<p>Note that I'm not looking for a solution that use a static default server-side breakpoint, and that on the client correct the app. I am looking for a solution that would return to the client the proper html structure according to its device. So it should work fine if he disables javascript on his browser.</p>
<hr>
<p>One could argue that I could render the html needed for both, and hide/show the required parts with plain CSS mediaqueries and <code>display: none</code>, but it would complicates the app and make it render a lot of unused html elements because generally it's unlikely that the user move above/under the breakpoint (I mean if he has a mobile device, the html elements for desktop will never be used)</p>
<p>Also, if I want to use inline-style, it becomes complicated because I have to render these inline styles for the correct width on the server.</p>
<p>I've <a href="https://github.com/reactjs/react-future/issues/8#issuecomment-53353098" rel="noreferrer">seen</a> some people are thinking about sniffing the browser UA to make an estimated guess of their viewport size. But even with some unsecure screen dimension detection, I'm not sure we can know the device screen orientation on the server-side.</p>
<p>Can I do anything to solve this problem?</p>

Declaring strings public static readonly versus public const versus public static const. <p>In each project we have there is a file used to store the various SQL statements used in that project. There are a handful of variations on how the class is declared and how the strings are declared.</p>
<p>Example class declartions:</p>
<pre><code>internal sealed class ClassName
internal static class ClassName
public sealed class ClassName
public static class ClassName
internal class ClassName
</code></pre>
<p>Example string declarations:</p>
<pre><code>internal const string stringName
internal static string stringName
public static readonly string stringName
public static string stringName
public const string stringName
</code></pre>
<p>I don't understand what the performance implications are between the different declarations. Is there a best practice for this situation/scenario? </p>

Does brand/hardware limit the distributions that are safe to run?. <p>I recently tried running Fedora 16 on my laptop and had problems with the fan. In particular, the fan would start, run at full power, and never turn off. I spent a few hours online looking for solutions but didn't find any. I then reverted back to Ubuntu and had the problem disappear (after some minor configuration). </p>
<p>I would really like to try different distributions, but I'm afraid that the hardware on my laptop would not be supported. Is there always a fix to these kinds of problems or should I just stick to what works? </p>

MacBook Pro 2012 HD locks on boot. <p>Today my laptop has started to lock the HD. When booted it either stays black with the fans going nuts or it loads up a dialog to reset pw. In this window I can choose startup disk from the top left menu. The dialog that opens allows me to unlock the HD but the system needs to reboot to use my HD as startup disk. And then it starts all over again...</p>

Solving PDE with Feynman-Kac Formula. <p>I have the following PDE:</p>
<p>$$\begin{cases}
\left (-\partial_t + \mu x \partial_x + \dfrac{1}{2} \sigma^2 x^2 \partial_x^2 \right )u = -f(t, x)\\
u(0, x) = 0
\end{cases}$$</p>
<p>where $f(t, x) = x^2 \left ( (\mu + \sigma^2 ) e^{\mu t} - \left (\mu + \frac{1}{2}\sigma^2\right )\right )$.</p>
<p>Since $\mu x \partial_x + \dfrac{1}{2} \sigma^2 x^2 \partial_x^2$ is the infinitesimal generator of a Geometric Brownian Motion with drift $\mu$ and volatility $\sigma$, by Feynman-Kac the solution should be given by:</p>
<p>$$u(t, x) = \mathbb{E}^x \left (\int_0^t f(s, X_s)dx\right )$$</p>
<p>where $X$ has dynamics</p>
<p>$$dX_t = \mu X_t dt + \sigma X_t dW_t.$$</p>
<p>I know that the exact solution should be $u(t, x) = \frac{1}{2} x^2 \left ( e^{(2\mu + \sigma^2) t} - 2e^{\mu t} + 1\right )$. However, when I try to compute the solution using Feynman-Kac, I get:</p>
<p>$$u(t, x) = \int_0^t \mathbb{E}^x (f(s, X_s))ds = \int_0^t x^2 e^{(2\mu + \sigma^2) s}\left ( (\mu + \sigma^2 ) e^{\mu s} - \left (\mu + \frac{1}{2}\sigma^2\right )\right ) ds$$ which doesn't agree with the above solution.</p>

Good resources for example process definitions of software development methodologies?. <p>Is there any website specifically for sharing and accessing actual software development processes implemented in software organizations? </p>
<p>There are lots of resources that give advices and descriptions for implementing these processes. They are very useful. But I think having actual example process definitions would be very useful as well. Specifically, I am now looking for an example process definition in CMMI. I overviewed several books but none of them presents any specific example implementation. </p>
<p>I think the authors are probably concerned that the readers might just copy these process definitions without understanding specific customization decisions in them. They are very rightful in this concern. But anyway, I think this is an important need for general software community. Understanding and interpreting an example document properly should be the responsibility of the reader. </p>
<p>If you don't know any good resource that shares specific implementations of the processes, what do you think about this need? Don't you think that we, software engineers and developers, should share our process definitions as we share our code?</p>

NETSH - How to import WIFI profile when WIFI NIC is not present. <p>I'm currently in process of creating standardised Winndows 10 image for kisok PC.</p>
<p>Now the problem I'm facing is that during install, when I try to preload WIFI profile using <code>netsh wlan add profile file=C:\wifi.xml user=all</code>, I get the error stating that <code>There is no wireless interface on the system</code>. Now the error itself makes sense, since USB WIFI adapter is physically not yet connected to the PC (we connect adapters to the PCs when they are mounted into kisok stand, OS install is done way beforehand).</p>
<p>I've already tried adding <em>fake</em> WIFI adapter using "Add legacy hardware" option in device manager, but unfortunately that didn't fool netsh into thinking that WIFI is present. </p>
<p>Is there any way other way I can preload WIFI profile into my image when there is no WIFI adpater connected or trick that would convince netsh that WIFI card is present when actually it is not? Maybe using WISM or some other tool?</p>

WPF: How to reference other controls within trigger Property property?. <p>I have a WPF page. Page has some content, but the last child component of page's root layout is a user control that I have created. It looks like this: </p>
<pre><code><UserControl DataContext=UserControlViewModel>
<UserControl.Resources>
<BooleanToVisibilityConverter x:Key="visibilityConverter" />
</UserControl.Resources>
<Grid
Name="grid"
Visibility="{Binding IsOn, Converter={StaticResource visibilityConverter}}">
<!-- Border to dim everything behind my user control -->
<Border Background="#000000" Opacity="0.4" />
<!-- The following border is red and holds the content -->
<Border
Width="{Binding ElementName=txt, Path=ActualWidth}"
Height="{Binding ElementName=txt, Path=ActualHeight}"
Margin="{Binding ElementName=txt, Path=Margin}"
HorizontalAlignment="{Binding ElementName=txt, Path=HorizontalAlignment}"
VerticalAlignment="{Binding ElementName=txt, Path=VerticalAlignment}"
Background="Red">
<TextBlock
Name="txt"
Width="200"
Height="100"
Margin="20"
HorizontalAlignment="Center"
VerticalAlignment="Center"
Text="This is my super awesome message!" />
</Border>
</Grid>
</UserControl>
</code></pre>
<p>By default, the <code>IsOn</code> property of the <code>UserControlViewModel</code> object is set to <code>false</code>, i.e. the user control is not visible. I have implemented some logic that changes this property to <code>true</code> and then the user control is displayed in front of all other components which are dimmed. This works well. </p>
<p>Now, I want to create a fade effect animation which would dim the components that are behind the user control once it becomes visible. Next, I want to make my red border that holds the content to fade in from the left hand side, so moving + fade. </p>
<p>Let's start with the fade effect first. I wrote this style to the <code>Border</code> that is supposed to do the dimming of background components: </p>
<pre><code><UserControl DataContext=UserControlViewModel>
<UserControl.Resources>
<BooleanToVisibilityConverter x:Key="visibilityConverter" />
</UserControl.Resources>
<Grid
Name="grid"
Visibility="{Binding IsOn, Converter={StaticResource visibilityConverter}}">
<!-- Border to dim everything behind my user control -->
<Border Background="#000000" Opacity="0.4">
<!-- The following style is new code -->
<Border.Style>
<Style TargetType="Border">
<Style.Triggers>
<Trigger Property="{Binding ElementName=grid, Visibility}" Value="Visible">
<Trigger.EnterActions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation
Storyboard.TargetProperty="Opacity"
From="0.0"
To="0.4"
Duration="0:0:1" />
</Storyboard>
</BeginStoryboard>
</Trigger.EnterActions>
</Trigger>
</Style.Triggers>
</Style>
</Border.Style>
</Border>
...
</code></pre>
<p>But there's the problem: I cannot set the binding on the trigger <code>Property</code>, because it is not a dependency property. I need a way to tell my trigger to fire once the <code>grid</code> has got the <code>Visibility</code> property set to <code>Visible</code>. Please help and thank you!</p>
<p>Second problem is, I don't know how to do the moving of the red border, so I need help around some scale transformations as well, I guess... Thanks once again!</p>

I really don't want to become an alcoholic.. Guess I'll just get to the point: I want to be the drunk me. Always. In any sort of social situation, drunk me is objectively a better person. Confident, an extrovert, quick witted with jokes, can't dance too well but *has the fucking confidence to just go and do it anyways.*
I'm also a broke university student for the most part. Sometimes I find web design gigs to do. Mostly I live on a shitty diet, though, to save cash. Lately I've been spending nearly all of my income on vodka. I buy vodka specifically because I only want to become drunk and nothing else is really important to me. I need to be drunk to feel like I'm worth anything. The only situation in which not being drunk is worth it is when I'm doing maths or programming, I just can't do those activities productively when drunk. Other than that, sober me is an awkward, useless mess who will say no to everything.
Don't really know what to do once my balance hits 0. Binge drinking gets expensive. Hiding not being sober can get pretty difficult. I usually need to drive somewhere at least twice a day.
At least I don't really have people who depend on me; just vice versa. If something were to happen then I don't think it'd be all that dramatically bad. But yeah. I want to be constantly and permanently drunk because it makes me an objectively better person, but it's expensive and I can't afford this lifestyle for too much longer. Shit sucks. | 0non-cybersec

Will getting a cat make my dog more "tolerant" of cats?. I have a mixed [Rhodesian Ridgeback](http://i.imgur.com/0tyUV.jpg), and I love her.
It's just that she has a really strong hunt drive which makes her go mental at the sight of cats. I have been training her and she is very obedient but cats are still an obstacle.
I can handle her, but I'm afraid other house members might have a harder time or that one day she will make a wrong identificatio (cat vs small child, almost happened once).
I don't like cats all that much (nil to none), but I have herd of a breed, [Pixie-Bob](http://en.wikipedia.org/wiki/Pixie-bob) that should have very convenient (dog like) characteristics and I don't mind getting one if it will ease her up.
TL;DL: Will getting a cat ease my dog up when seeing other cats?
Edit: For people who want the answer but skip the reading:
1. High prey drive doesn't go away, the dog was born with that instinct and getting a cat would (if they get along) probably only make the dog tolerant of that specific cat
2. Forcing a relationship between the dog and the cat (if they don't get a long or when trying to get them to get along) might might end up badly (usually for the dog's eye).
3. More specific for people who don't fancy cats: a cat is a long term commitment, getting one to serve a purpose rather then actually wanting one would be a bad idea (abandonment, which is bad mmkay).

What games has your group put away for good?. My group has tried so hard with Dark Darker Darkest, but every time we play it, it ends up with arguments, frustration, constantly checking rules, and overall just a general lack of fun whatsoever. So after this last time, I put the game up on my highest shelf, doubting it will ever see the light of day again. I really wanted to like this game ever since I backed it on Kickstarter. But since the purpose of game night is fun, and this game never provided us with any, we have unofficially retired it. | 0non-cybersec

Apple Push Notifications in Bulk. <p>I have an app that involves sending Apple Push Notifications to ~1M users periodically. The setup for doing so has been built and tested for small numbers of notifications. Since there is no way I can test sending at that scale, I am interested in knowing whether there are any gotchas in sending bulk push notifications. I have scripts written in Python that open a single connection to the push server and send all notifications over that connection. Apple recommends keeping it open for as long as possible. But I have also seen that the connection terminates and you need to reestablish it. </p>
<p>All in all, it is disconcerting that successful sends are not acknowledged, only erroneous ones are flagged. From a programmer's standpoint instead of simply checking one thing "if (success)" you now need to watch for numerous things that could go wrong.</p>
<p>My question is: What are the typical set of errors that you need to watch out for to make sure your messages don't silently disappear into oblivion? The connection closing is an easy one. Are there others?</p>

Scientific soundness of computer science papers. <p>First of all, this question relates to an issue that affects several areas of science, but since StackExchange doesn't have a meta science section I'll make it specific to computer science, which is pertinent because the solution to the bigger problem may actually come from computer science.</p>
<p>In the context of the news that <a href="http://retractionwatch.com/2014/02/24/springer-ieee-withdrawing-more-than-120-nonsense-papers" rel="nofollow">Springer and IEEE published more than 120 nonsense papers</a> my question is as follows:</p>
<p>What rigourous set of methods can we apply to the process of publishing scientific papers so that we can quickly verify the reproducibility of the experiments?</p>
<p>We already have systems like <a href="http://turnitin.com/" rel="nofollow">Turnitin</a> that are highly efficient at detecting plagiarism, yet I don't know of any system that can score a piece of work on its <em>scientific soundness</em>.</p>
<p>Is there any ongoing work related to this? I found out about <a href="https://en.wikipedia.org/wiki/Semantic_publishing" rel="nofollow">Semantic Publishing</a> whilst composing this question, but I have no idea what other approaches, if any, are being actively worked on.</p>

What's the file format of "application/x-executable". <p>No no no no. I can run the file. My favorite game is that file format and I can run it just fine. Same as other programs with it. My question is what the file format of it? You know. Things like <code>.sh</code>, or <code>.exe</code>, <code>.txt</code>, <code>.rar</code>, etc, etc. So, if you know just tell me.</p>
<p>So you know, the question isn’t about the game. It’s about the file format. The question has nothing to do about the game. And I already figured out about the file format. It’s <code>.86_64</code>. I didn’t notice the answer that was posted to this question so I had to figure it out myself. For anyone who is reading this now, I will close this question soon.</p>

My program's notifyicon get duplicated when using Form.Show() to call a preloader form. <p><strong>EDIT:</strong> Silly me. My preloader actually shows up all the time even with simple <code>Loading.Show();</code> but it just was below my web browser. I already posted a solution below. Please check it up if you interested.</p>
<p>My program has no form but shows as a notifyicon in the notification area (My main form is actually hidden to use as dummy form for notifyicon and other controls). It run by getting called from web browser using URI scheme (<code>tkh</code>). If my program is already running and user called it from browser, it will do things according to its argument. For example, if an user called it with <code>tkh:readCard</code>, my program will do stuff in <code>readCard</code> function.</p>
<p>Here's my code for reading argument from URI scheme</p>
<pre><code>public string CommandLine { get; set; }
public bool CheckForProtocolMessage(Uri uri)
{
if (uri.ToString().Length > 1)
{
string[] args = uri.ToString().Split(':');
CommandLine = args[1];
if (args[0].Trim().ToUpper() == "TKH" && args.Length > 1)
{
if (args[1].Length > 1)
{
switch (args[1].Trim().ToUpper())
{
case "READCARD":
if (hasCardReader == true)
{
var bw_readCard = new BackgroundWorker { WorkerReportsProgress = true };
bw_readCard.DoWork += delegate
{
preloaderShow();
readCard();
preloaderClose();
};
bw_readCard.ProgressChanged += delegate { };
bw_readCard.RunWorkerCompleted += delegate { };
bw_readCard.RunWorkerAsync();
bw_readCard.Dispose();
return true;
}
else
{
MessageBox.Show("Try again", "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
return false;
}
case "READCARD_IDONLY":
if (hasCardReader == true)
{
var bw_readCard_IDOnly = new BackgroundWorker { WorkerReportsProgress = true };
bw_readCard_IDOnly.DoWork += delegate
{

}
}
}
}
}
return false;
}
</code></pre>
<p><code>preloaderShow();</code> and <code>preloaderClose();</code> are for show and close a preloader form. (My preloader form named "Loading")</p>
<p>Here's the <code>preloaderShow();</code> function</p>
<pre><code>private void preloaderShow()
{
Loading Loading = new Loading();
Loading.Show();
}
</code></pre>
<p>and the <code>preloaderClose();</code> function</p>
<pre><code> private void preloaderClose()
{
Loading Loading = new Loading();
Application.OpenForms
.OfType<Form>()
.Where(form => String.Equals(form.Name, "Loading"))
.ToList()
.ForEach(form => form.Close());
}
</code></pre>
<p>My problem is if the program isn't running, the preloader shows up and do stuff normally. But if it already running, the preloader won't show up but stuff in <code>readCard();</code> and <code>readCard_IDOnly();</code> works normally.</p>
<p>If I change my preloaderShow(); like this,</p>
<pre><code>private void preloaderShow()
{
Loading Loading = new Loading();
Form1 Form1 = new Form1(); // Declared this even without put Form1 into .Show() also make the program's notifyicon duplicate.
Loading.Show(Form1);
}
</code></pre>
<p>the preloader will show up and the notifyicon get duplicated Like below </p>
<p><a href="https://i.stack.imgur.com/otuVK.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/otuVK.png" alt="but notifyicon will duplicated and cannot be closed"></a></p>
<p>I will need to close down "main" notifyicon to make it all gone.</p>
<p>What do I need to do? Thanks.</p>

Raising exception in a generator, handle it elsewhere and vice versa in python. <p>I'm thinking in a direction more advanced as well as difficult to find solutions this problem. Before coming to any decision, I thought of asking expert advice to address this problem. </p>
<p>The enhanced generators have new methods .send() and .throw() that allow the caller to pass messages or to raise exceptions <em>into</em> the generator (coroutine).</p>
<p>From python documentation: This can be very handy, especially the .throw() method that requests the generator to handle exceptions raised in the caller. </p>
<p><strong>Request #1: Any example code for the above statement. I didn't find any code snippets for this explanation.</strong></p>
<p>However, I'm considering the inverse problem as well: can a generator raise an exception, pass it to the caller, let the caller "repair" it, and continue the generator's own execution? That is what I would like to call a "reverse throw".</p>
<p><strong>Request #2: Any example code for the above statement. I didn't find any code snippets for this explanation.</strong></p>
<p>Simply raising exceptions in the generator is not OK. I tried "raise SomeException" in the generator, and that didn't work, because after a "raise" the generator can no longer be executed --- it simply stops, and further attempts to run the generator cause the StopIteration exception. In other words, "raise" is much more deadly than "yield": one can resume itself after yielding to the caller but a "raise" sends itself to the dead end.</p>
<p>I wonder if there are simple ways to do the "reverse throw" in Python? That will enable us to write coroutines that cooperate by throwing exceptions at each other. But why use exceptions? Well, I dunno... it all began as some rough idea.</p>
<p>CASE STUDY CODE:</p>
<pre><code>class MyException(Exception):pass
def handleError(func):
''' handle an error'''
errors =[]
def wrapper(arg1):
result = func(arg1)
for err in findError(result):
errors.append(err)
print errors
return result
return wrapper
def findError(result):
'''
Find an error if any
'''
print result
for k, v in result.iteritems():
error_nr = v % 2
if error_nr ==0:
pass
elif error_nr > 0:
yield MyException
@handleError
def numGen(input):
''' This function take the input and generates 10 random numbers. 10 random numbers are saved in result dictionary with indices. Find error decorator is called based on the result dictionary'''
from random import randint
result= {}
errors = []
for i in range(9):
j = (randint(0,4))
result[i] = input + j
return result
if __name__ == '__main__':
numGen(4)
</code></pre>
<p>Could anyone explain please both the ideas based on case study example(Raising exception in a generator and handle it elsewhere vice versa)? I do expect pro's and con's of both methods.</p>
<p>Thanks in advance.</p>
<p>Looking for an answer drawing from credible and/or official sources.</p>

<p>Though it all seems fine and have scanned by amavisd-new, it goes to spam. I don't necessarily ask why but if it's related to not being scanned correctly, I need to fix this issue. </p>
<p>And here's how I use CLAMAV in /etc/amavisd.conf file:</p>
<pre><code>['ClamAV-clamd',
\&ask_daemon, ["CONTSCAN {}\n", "/var/run/clamav/clamd.sock"],
qr/\bOK$/m, qr/\bFOUND$/m,
qr/^.*?: (?!Infected Archive)(.*) FOUND$/m ],
</code></pre>
<p>The file clamd.sock is not exist under /var/run/clamav/ dir, and this dir is chowned by clamav user and group (the service doesn't start when it's not). I don't know if it's a dynamic file that is being created and deleted on runtime but I don't think there's any issue with permissions, perhaps some process or service is missing to create the file. </p>
<p>Any ideas? Thanks in advance.</p>

How to create custom section titles with a "<title> <number>" format in ConTeXt?. <p>I am making a book, with chapters titled "Week 1", "Week 2", "Week 3", etc., and sections titled "Activity 1", "Activity 2", "Activity 3", etc., and other sections titled "Presentation 1", "Presentation 2", "Presentation 3", etc.</p>
<ul>
<li>The preceding numbers, e.g. "1.1 Activity 1", are not used.</li>
<li>No other text, e.g. "Week 1 Topic" appears in the text.</li>
<li>The numbers for sections never reset.</li>
</ul>
<p>Here is a sample table of contents, showing how I hope it will appear:</p>
<pre><code> ______________________
| |
| Contents |
| |
| Week 1 |
| Activity 1 |
| Activity 2 |
| Presentation 1 |
| Week 2 |
| Activity 3 |
| Activity 4 |
| Presentation 2 |
|______________________|
</code></pre>
<p>The document occassionally has other orginary chapter and section titles as well. These should get the same font formatting, but otherwise, not be modified, and appear without any number, e.g., using chapter titles "Forward", "Conclusion", and a section title called "Notes":</p>
<pre><code> ______________________
| |
| Contents |
| |
| Forward |
| Week 1 |
| Activity 1 |
| Activity 2 |
| Presentation 1 |
| Week 2 |
| Activity 3 |
| Notes |
| Conclusion |
|______________________|
</code></pre>
<p>I have tried my own solution, by removing the preceding numbers using <code>\setuphead[chapter][number=no]</code>, creating counters, e.g. <code>\definenumber[weekcount]</code>, then defining custom macros which call for chapter titles to use these counters, however, my solution does not work:</p>
<pre><code>\definenumber[weekcount]
\definenumber[activitycount]
\definenumber[presentationcount]
\setnumber[weekcount]{1}
\setnumber[activitycount]{1}
\setnumber[presentationcount]{1}
\define\week{\chapter{Week~\getnumber[weekcount]}\incrementnumber[weekcount]}
\define\activity{\section{Activity~\getnumber[activitycount]}\incrementnumber[activitycount]}
\define\presentation{\section{Presentation~\getnumber[presentationcount]}\incrementnumber[presentationcount]}
\setuphead[chapter][number=no]
\setuphead[section][number=no]
\starttext
\week
\activity
This is some text.
\activity
This is some text.
\presentation
This is some text.
\week
\activity
This is some more text.
\activity
This is some more text.
\presentation
This is some more text.
\stoptext
</code></pre>
<p>This results in this:</p>
<pre><code> ______________________
| |
| Contents |
| |
| Week |
| Activity |
| Activity 1 |
| Presentation |
| Week |
| Activity |
| Activity 1 |
| Presentation |
|______________________|
</code></pre>
<p>If you remove <code>\setuphead[chapter][number=no]</code>, results are also unusual:</p>
<pre><code> ______________________
| |
| Contents |
| |
| 1. Week 1. |
| 1.1 Activity 1. |
| 1.2 Activity 1.1 |
| 1.2 Presentation 1. |
| 2. Week 2. |
| 2.1 Activity 2 |
| 2.2 Activity 2.1 |
| 2.3 Presentation 2. |
|______________________|
</code></pre>
<ul>
<li>Why is the numbering of the counters appear in this manner, when used inside section titles?</li>
<li>How can I create custom chapter titles using a "Week " format, and similarly formatted section titles?</li>
</ul>

Continuity of an extended rate of variation?. <p>Let $f:\mathbb R\to \mathbb R$ be a $C^1$ function. </p>
<blockquote>
<p>Then Prove or disprove that $g:\mathbb R^2\to \mathbb R$ define by
$$g(x,y) = \begin{cases}\frac{f(x)-f(y)}{x-y}&\text{if $x\neq y$}\\
f'(x)&\text{if $x= y$}\end{cases}$$
is a continuous function.</p>
</blockquote>
<p>Note that $C^1$ Continuity must be crucial since a blatant counter example given by the function
$$f(x) = \begin{cases}x^2\sin \frac{1}{x}&\text{if $x\neq 0$}\\
0&\text{if $x= 0$}\end{cases}$$
which differentiable on $\mathbb R$ but not $C^1$ because the derivative is not continuous at $x=0.$</p>

pandas dataframe create new columns and fill with calculated values from same df. <p>Here is a simplified example of my df:</p>
<pre><code>ds = pd.DataFrame(np.abs(randn(3, 4)), index=[1,2,3], columns=['A','B','C','D'])
ds
A B C D

2 0.268205 0.718933 1.459374 0.758887
3 0.680566 0.538655 0.038236 1.169403
</code></pre>
<p>I would like to sum the data in the columns row wise:</p>
<pre><code>ds['sum']=ds.sum(axis=1)
ds
A B C D sum
1 0.095389 0.556978 1.646888 1.959295 4.258550
2 1.076190 2.668270 0.825116 1.477040 6.046616
3 0.245034 1.066285 0.967124 0.791606 3.070049
</code></pre>
<p>Now, here comes my question! I would like to create 4 new columns and calculate the percentage value from the total (sum) in every row. So first value in the first new column should be (0.095389/4.258550), first value in the second new column (0.556978/4.258550)...and so on...
Help please </p>

What's the framework mechanism behind dependency properties?. <p>I have been reading about dependency properties in several books but all have one thing in common, they just tell us how they are implemented( using <code>static readonly DependencyProperty</code> etc.) but does not tell the exact way they work from inside. </p>
<p>I mean they are implemented as static but still applies to all objects.<br>
Second point of confusion is attached properties. </p>
<p>Is there any tutorial available that can explain all these concepts in an easy way?</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:
