How can I store an object File that only exists in memory as a file inside of my storage system? : <p>My programm has just recieved an <em>Object</em> that is instance of <em>File</em>. How can I save said Object as a file?
I want the file to be stored in a human readable format which is why just writing the Object into a new file like <a href="https://stackoverflow.com/questions/2744962/load-store-objects-in-file-in-java">here</a> wont do the trick.</p>
<p>I also can't just copy the file like <a href="https://www.journaldev.com/861/java-copy-file" rel="nofollow noreferrer">here</a> because the file I allready know only exists in Memory, hence if I set it as source it wont be recocnized.</p>

Problems accessing Calendar using EKEventStore on OSX Sierra with Swift 3 : <p>This appears very simple, but I've been struggling for several days to get access to the Calendar on OSX. I have switched on the App Sandbox capability, and I've ticked the "Calendar" box in App Data. I have created very simple app with the following view controller class:</p>
<pre><code>import Cocoa
import EventKit
class ViewController: NSViewController {
var eventControl = EKEventStore()
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
override var representedObject: Any? {
didSet {
// Update the view, if already loaded.
}
}
}
</code></pre>
<p>As you can see, the only lines of code I've added are to import EventKit and to initialise eventControl.</p>
<p>When I run this in debug, I get an error at the eventControl initialisation line</p>
<pre><code>2016-10-28 15:02:00.056521 calendarTest[4105:847101] CoreData: XPC: Unable to load metadata: Error Domain=NSCocoaErrorDomain Code=134070 "An error occurred in the persistent store." UserInfo={Problem=request failed, insufficient permission}

Conversion of array of double value in to a character array : I need to send an array of 4 double value in to a character buffer of size 8 byte and also
would like to extract the value from the character array in to double value for its usage.
-I am trying with the below code but not getting correct output as
char str is of size 8 byte is too little to store 4 double value !!
-There might be some bit operation could solve the issue!!
Ex:
#include<stdio.h>
#include<string.h>
#include<stdlib.h>
int main()
{
char str[8]={'\0'};
double x=-10.456678,p=12.678906,q=80.8956876,r=360.67,y,z,h,k;
sprintf(&str[0],"%2.6f",x);
sprintf(&str[1],"%2.6f",p);
sprintf(&str[2],"%2.6f",q);
sprintf(&str[3],%3.4f",r);
//Extracting the same from str
y=atof((char *)&str[0]);
z=atof((char *)&str[1]);
h=atof((char *)&str[2]);
k=atof((char *)&str[3]);
printf("\ny= %2.6f",y);
printf("\nz= %2.6f",z);
printf("\nh= %2.6f",h);
printf("\nk= %2.6f",k);
return 0;
}
Could anyone please answer
Thanks in Advance!!

How to prevent pull-down-to-refresh of mobile chrome : <p>I want to prevent pull-down-to-refresh of mobile chrome(especially iOS chrome). My web application has vertical panning event with device-width and device-height viewport, but whenever panning down, mobile chrome refreshes itself because of browser's default function. Plus, on Safari browser, screen is rolling during panning event. I want to disable these moves.</p>
<p>Of course, I tried event.preventDefault(); and touch-action: none; But it doesn't look work. Should I add eventListner and touch-action "on body tag"? I expect useful answer with example.</p>

Different ports for frontend and backend. How to make a request? : <p>Using Angular-CLI as a frontend. 4200 port</p>
<p>Using Express as a backend. 8080 port</p>
<p>Directories look like:</p>
<pre><code>Application
- backend
- ...Express architecture
- frontend
-...Angular2 architecture
</code></pre>
<p>So I'm running two projects, two commanders, one for frontent, second one for backend. <code>node app.js</code> for backend (8080), <code>ng serve</code> for frontent (4200).</p>
<p>Let's assume that I have a layer in backend which returns some string.</p>
<pre><code>app.get('/hello', function(req, res) {
res.send("Hello!");
}
</code></pre>
<p>How can I make a request from frontend to backend and get that string? I don't want to know how exactly should I use Angular2 because that's not the point. I'm asking, what technology should I use to be able connect these two (frontent and backend) sides on different ports. If I just run them and make a request from frontend, I'll get an error because it can't find <code>/hello</code> url.</p>

Array doesn't save swift : getting a Json Object from a rest web service i get the data from the object and i want to show it in a tableview
`class TableViewController1: UITableViewController {

self.resultat1 = jsonResult["meme_categorie"] as? NSArray
self.compteur1 = self.resultat1!.count
print(self.compteur1!)

Then My problem is that this array stays nil `self.prixProduit.append(self.vt2!)`

HTTPURLResponse allHeaderFields Swift 3 Capitalisation : <p>Converting to Swift 3 I noticed a strange bug occur reading a header field from HTTPURLResponse.</p>
<pre><code>let id = httpResponse.allHeaderFields["eTag"] as? String
</code></pre>
<p>no longer worked.</p>
<p>I printed out the all headers dictionary and all my header keys seem to be in Sentence case.</p>
<p>According to Charles proxy all my headers are in lower case. According to the backend team, in their code the headers are in Title-Case. According the docs: headers should be case-insensitive. </p>
<p>So I don't know which to believe. Is anyone else finding in Swift 3 that their headers are now being turned into Sentence case by iOS? If so is this behaviour we want?</p>
<p>Should I log a bug with Apple or should I just make a category on HTTPURLResponse to allow myself to case insensitively find a header value.</p>

rstudio data column matching : I'm currently working on the project where I have about multiple CSV files need to match all combinations of events people attended by matching their customer id.

How can I make a React "If" component that acts like a real "if" in Typescript? : <p>I made a simple <code><If /></code> function component using React:</p>
<pre><code>import React, { ReactElement } from "react";
interface Props {
condition: boolean;
comment?: any;
}
export function If(props: React.PropsWithChildren<Props>): ReactElement | null {
if (props.condition) {
return <>{props.children}</>;
}
return null;
}
</code></pre>
<p>It lets me write a cleaner code, such as:</p>
<pre><code>render() {
...
<If condition={truthy}>
presnet if truthy
</If>
...
</code></pre>
<p>In most cases, it works good, But when I want to check for example if a given variable is not defined and then pass it as property, it becomes an issue. I'll give an example:</p>
<p>Let's say I have a component called <code><Animal /></code> which has the following Props:</p>
<pre><code>interface AnimalProps {
animal: Animal;
}
</code></pre>
<p>and now I have another component which renders the following DOM:</p>
<pre><code>const animal: Animal | undefined = ...;
return (
<If condition={animal !== undefined} comment="if animal is defined, then present it">
<Animal animal={animal} /> // <-- Error! expected Animal, but got Animal | undefined
</If>
);
</code></pre>
<p>As I commented, althought in fact animal is not defined, I've got no way of telling Typescript that I already checked it. Assertion of <code>animal!</code> would work, but that's not what I'm looking for.</p>
<p>Any ideas?</p>

CPP - Convert source code from Windows to Linux : <p>I have a single-file CPP app, built for Windows and is running in command line only.</p>

<pre><code>#include <iostream>
#include "setjmp.h"
#include "windows.h"
#include "time.h"

<p>It also uses all kinds of unsigned integers (uint8, uint16, uint32, uint64).</p>
<p>Other than this there aren't any other Windows-specific APIs.</p>

Has anyone reversed engineered the protocol used by Apple's iOS Remote app for controlling an Apple TV over IP? : <p>I'm curious if it's possible for me to write programs that can control an Apple TV, specifically an Apple TV 4th gen running tvOS 9.1.1, like Apple's Remote app for iOS can. I'd like to send it commands for navigating in the four cardinal directions, selecting an item on the screen, going up the navigation stack -- essentially what Apple's Remote app can do.</p>
<p>Has anyone done any work reverse engineering the protocol it uses? Cursory Googling only has so far yielded out of date results about earlier generation Apple TVs and the DAAP protocol which looks like something different than what I want.</p>

matlab execute script from command linux line : <p>is there a way to run a matlab script from linux command line?
For instance, I have the following simple script "test.m":</p>
<pre><code>x = [1,2,3];
y = [2;3;4];
prod = x*y
disp(prod)
</code></pre>
<p>So what I want is to be able to execute that script from the linux command line without opening the matlab GUI or the matlab command line. That is, I expect something like that:</p>
<pre><code>~$ matlab test.m
</code></pre>
<p>and I expect to see the result of the product on the linux command line.</p>
<p>I know that you can do that with python e.g.,</p>
<pre><code>~$ python test.py
</code></pre>
<p>but was wondering if the same can be achieved with matlab. </p>

Postgres sessions are idle with query = COMMIT or ROLLBACK : <p>I have a Postgres 9.5 database for a web-based Java application. Sometimes, the number of sessions suddenly spikes up due to a long running query, and these sessions are not cleared immediately. When I check pg_stat_activity, query column shows COMMIT or ROLLBACK with a stage of idle. This is causing Postgres to hit high thresholds of max_connections, which can possibly cause Production outage.</p>
<p>query | ROLLBACK
state | idle
count | 167</p>
<p>query | COMMIT
state | idle
count | 280</p>
<ol>
<li>What are these COMMIT/ROLLBACK idle sessions? </li>
<li>How can I get these idle sessions to clear immediately? </li>
<li>How can I reduce the number of these idle sessions from being created?</li>
</ol>
<p>Thanks</p>

LocalStorage Saving as Strings : <p>I'm trying to make a speeding application that asks the user to input a pre-defined speed limit through an input, I have used local storage to store the number but it stores it like "number" instead of just the number it places quotation marks around them making it a string and useless in my application.</p>
<p>Here is the JS</p>
<pre><code> var limit = 20;
var limitfield = document.getElementById('limit1') //Places limit1 field from HTML into variable
limitfield.addEventListener('input', updateStorage); //Adds eventlistener to listen to input in limit1 field then call method
function updateStorage (){
localStorage.setItem('limitfield', limitfield.value); //After obtaining the input from eventlistener store the value in variable
setPreference();
}
function setPreference(){
limit = localStorage.getItem('limitfield'); //variable created that retrieves value

HTTP Get request from angular to spring backend being blocked by CORS policy : <p>I have a @RestController in my java spring backend:</p>

<pre><code>Access to XMLHttpRequest at 'http://localhost:8080/api/getItems' from origin
'http://localhost:4200' has been blocked by CORS policy: Response to
preflight request doesn't pass access control check: No 'Access-Control-
Allow-Origin' header is present on the requested resource.
</code></pre>
<p>But I am not sure why, because I am adding the correct header in Angular:</p>
<pre><code>getItems() {
this.http.get('http://localhost:8080/api/getItems',
{headers: new HttpHeaders({
'Access-Control-Allow-Origin': 'http://localhost:4200',
'Access-Control-Allow-Methods': 'GET, POST, PUT',
'Access-Control-Allow-Headers': 'Content-Type'
}
)})
.subscribe(
data => {console.log(data);
});
}
</code></pre>
<p>The get request does work in Postman, but I know that the browser is what is causing the problem, and requires that the 'Access-Control-Allow-Origin' header to be present, which I added.
It compiles, but it seems like it's not adding the headers correctly. Does anyone know what's going on here?</p>

How to keep footer at the bottom of the page and below content in AngularJS? : <p>I have tried to keep the footer below some content with various methods, but it seems that the solutions don't behave as expected with AngularJS's dynamic content.</p>
<ul>
<li><p>When the page is mostly blank, I want the footer to be at the bottom of the page</p></li>
<li><p>When the page expands (or just big in general), I want the footer to be pushed below the content (<em>not sticky to the page itself</em>)</p></li>
<li><ul>
<li>The same logic should follow when I redirect the page</li>
</ul></li>
</ul>
<p>Here is a small demo that I made to illustrate my attempt. I tried using <code>position: absolute;</code> for my footer, but I don't know how to change that (<em>or use alternatives</em>) once the content expands.</p>

A segementation fault : So I am currently working on this project for school, where I am implementing an algorithm to find a solution for the 'knight game'( it's about finding the shortest way from the top left corner of the board to the bottom right corner), but I've been getting this segmentation fault for three days now, I've checked every pointer I used and everything seems right.
I implented " searching algorithms, bfs and dfs and ucs, the first two ones work fine, but ucs gives me the segmentation fault, even though they use the same thing except a popBest function.
Here are some pictures of the ucs and popBest function :
Item *popBest( list_t *list ) // and remove the best board from the list.
{
assert(list);
assert(list->numElements);
int min_f;
Item *item = list->first;
Item *best;
min_f = list->first->f;
while (item) {
if (item->f < min_f) {
min_f = item->f;
best = item;
}
item = item->next;
}
//item = onList(list, board);
delList(list, best);
return best;
}
void ucs(void)
{
Item *cur_node, *child_p, *temp;
while ( listCount(&openList_p) ) { /* While items are on the open list
printLt(openList_p );
/* Get the first item on the open list
cur_node = popBest(&openList_p);
//printf("%d %f\n", listCount(&openList_p), evaluateBoard( cur_node ));
printBoard(cur_node);
addFirst(&closedList_p, cur_node);
if ( evaluateBoard(cur_node) == 0.0 ) {
showSolution(cur_node);
printf("\nParcours en largeur (bfs)\n" );
return;
}
else {
for (int i = 0; i < MAX_BOARD; i++) {
child_p = getChildBoard( cur_node, i );
if (child_p != NULL) {
child_p->f = cur_node->f+1;
temp = onList(&openList_p, child_p->board);
if (temp ==NULL) addLast( &openList_p, temp);
else if (temp != NULL && child_p->f < temp->f )
{
delList(&openList_p, temp);
addLast( &openList_p, temp);
}
}
}
}
}
return;
}
All the functions work fine for bfs and dfs, the only difference is the popBest function.
It would be awesome if someone can guide me as I am still a beginner, thanks in advance.
PS : sorry for the poor English, I am not a native.

What is the appropriate machine learning algorithm for a restaurant's sales prediction? : <p>I want to estimate the sales of a restaurant three days in advance, so that the staff can order fresh ingredients in time. I started off using linear regression, but noticed the following:
For the restaurant it is worse, if a customer won't get the food he ordered, compared to the case that food that is eventually thrown away.
I figured I might just need a skewed cost function, but I am not sure. Maybe there is something already implemented. </p>
<p>Another question: Some days, there are some reservations (pre-orders) for the restaurant, so I know they will need at least a certain amount. How to include that?</p>
<p>Thank you!</p>

Laravel 5.3 Password Broker Customization : <p>Does anyone know how to override the functions used within laravel's password broker? I know the docs:</p>
<p><a href="https://laravel.com/docs/5.3/passwords#resetting-views" rel="noreferrer">https://laravel.com/docs/5.3/passwords#resetting-views</a></p>
<p>Give information on what to do for things like views and a few surface level things but it's not clear at all really or maybe I'm not reading it enough times. </p>
<p>I already know how to override the <code>ResetsPasswords.php</code> Trait but overriding the functionality of the <code>Password::broker()</code> is for the next layer in. </p>
<p>If there is more information needed I can kindly provide some. </p>
<p>Thank you in advance.</p>
