macOS (10.13 High Sierra) no longer stores screensaver settings in com.apple.screensaver : <p>So far my project had been relying on the following commands in order to tweak screensaver settings:</p>
<pre><code>defaults write com.apple.screensaver askForPasswordDelay 0
defaults write com.apple.screensaver askForPassword true
</code></pre>
<p>As of macOS High Sierra (10.13) it seems like these settings are no longer stored in com.apple.screensaver</p>
<p>I'd like to avoid Apple Script to achieve such thing, any suggestions?</p>

How to retrive a Tags from database? : I'm trying to retrieve a tags from database in my view and show it in post . but I have no idea of how I can done this ..
Here is my controller :
public async Task<ActionResult> Create(Book model)
{
if (ModelState.IsValid)
{
if(model.TagsListing != null)
{
Collection<Tag> postTags = new Collection<Tag>();
var s = model.TagsListing.ToString();
string[] newTags = s.Split(',');
foreach (var val in newTags)
{
Tag iTag = new Tag
{
Name = val
};
db.Tags.Add(iTag);
postTags.Add(iTag);
}
model.Tags = postTags;
}
db.Books.Add(model);
await db.SaveChangesAsync();
return RedirectToAction("Index");
}
ViewBag.User_ID = new SelectList(db.AspNetUsers, "Id", "Email");
ViewBag.Category_id = new SelectList(db.Categories, "Category_id", "Category_name");
return View(model);
}
and here is few pictures for my database :

Trying to create a simple recyclerView in Kotlin, but the adapter is not applying properly : <p>I'm trying to create a simple recyclerView in Kotlin with data that I get via Volley (which I have confirmed returns the correct data), I keep running to the error <code>E/RecyclerView: No adapter attached; skipping layout</code> when in fact I have specified an adapter with the custom adapter class that I created:</p>
<pre><code>class ImageAdapter(var c: Context, var list: ArrayList<Image>) : RecyclerView.Adapter<ImageAdapter.ViewHolder>() {
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ViewHolder? {
val layoutInflater = LayoutInflater.from(parent.context)
return ViewHolder(layoutInflater.inflate(R.layout.image_cardview, parent, false))
}
override fun onBindViewHolder(holder: ViewHolder, position: Int) {
val imageUrl = list[position].url
val submitter = list[position].submitter
val color = list[position].color
holder.submitterTV.text = submitter
holder.card.setCardBackgroundColor(Color.parseColor(color))
}
override fun getItemCount() = list.size
class ViewHolder(itemView: View): RecyclerView.ViewHolder(itemView){
val card = itemView.card
val submitterTV = itemView.submitter
val imageView = itemView.image
}
}
</code></pre>
<p>This is my MainActivty class, where I make the actual call for the JSON and attempt to attach my adapter with my ArrayList that I have created:</p>
<pre><code>class MainActivity : AppCompatActivity() {
val images = ArrayList<Image>()
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
imageList.layoutManager = LinearLayoutManager(applicationContext)
request("https://api.unsplash.com/photos/curated/?client_id=API_KEY")
imageList.adapter = ImageAdapter(applicationContext, images)
}
private fun request(url: String) {
val queue = Volley.newRequestQueue(this)
val stringRequest = JsonArrayRequest(url, Response.Listener<JSONArray> { response ->
try {
for (i in 0..(response.length() - 1)) {
val image: Image = Image(response.getJSONObject(i).getJSONObject("urls").getString("full"), response.getJSONObject(i).getJSONObject("user").getString("username"), response.getJSONObject(i).getString("color"))
images.add(image)
}
imageList.adapter.notifyDataSetChanged()
} catch (e: JSONException) {
e.printStackTrace()
}
}, Response.ErrorListener { })
queue.add(stringRequest)
}
}
</code></pre>
<p>I have created a custom data class <code>Image</code> which stores three fields: the imageUrl, submitter and color, all of which are derived from the JSON. I thought that calling <code>notifyDataSetChanged()</code> on my adapter after the request was completed would allow the recyclerView to get updated and show the items, but nothing at all shows up on the screen. Does anyone have any idea as to where I messed up?</p>

Git pull but never push file : <p>I couldn't find anything specific to this but if I missed it please let me know.</p>
<p>I have a file in git which needs to be there. Once pulled down each individual will need to edit it to add their own credentials to it. When edited by the individual I do not want it to show up as having been changed or anything because we want to keep the generic file without credentials in our repo. Is there an option to have a file set up as "Pull this file but never push it"?
Currently the setup we have is the file is named Upload.bat_COPY_EDIT_RENAME, which hopefully makes it obvious what to do, and I have Upload.bat in the .gitignore. I'd like something more idiot proof.</p>
<p>I know there are options like --assume-unchanged but I don't want to have to run that every time and it seems kind of like a bandaid fix which could potentially cause problems later.</p>
<p>Thanks for your help!</p>

Does Java's lack of multiple inheritance hurt its potential for Android game development? : <p>I'm currently enrolled in a mobile app development class, and I have an idea for a game that I'd like to do that involves virtual pets. I'm confident that I'll be able to utilize Java's capabilities for this class without a problem, but further down the line if I wanted to, say, fuse pets and/or breed, I imagine it might become difficult to implement my ideas using Java. </p>
<p>I know that objects can inherit from multiple interfaces and there are ways of obtaining variables through other means, but in terms of code and app efficiency, would I be better off using another language down the line?</p>
<p>Really looking forward to this discussion, as I enjoy hearing the pros and cons of each side. Java's my favorite language at the moment because I'm most familiar with it, but even so... I'd love to branch out if I'd be better off doing so. I've looked this up using search engines many times but I thought this would be a more hands-on approach to engage with people in conversation as opposed to simply reading past threads. </p>
<p>Thanks in advance!</p>

Get absolute file path of FileField of a model instance in Django : <p>I have a page where people can upload files to my server.</p>
<p>I want to do something with the file in Celery. So, I need to know the absolute filepath of the uploaded FileFiled of my Model.</p>
<p>Let's say I queried the model and got the instance.
Now I need to get the absolute file path including the filepath.</p>
<p><code>obj = Audio.objects.get(pk=1)</code></p>
<p>I'm currently trying <code>obj.filename</code> and it's only printing the file name and not the absolute path.</p>
<p>I know I can get the upload path I input into <code>upload_to</code> and media directory, but I was wondering if there was a more DRY and automatic approach.</p>
<p>How do I get the <code>absolute path</code> of <code>file</code> which is a file filed in <code>obj</code>?</p>

Excel VBA, code to count the # of filled cells, then find highest and 2nd highest and subtract the corresponding column #'s : <p>I'm looking to count the # of items in a list from A11 to A90. And if that number is even subtract the max value from the 2nd max and then 3rd max from 4th max, etc.. If it's odd then it would start at the 2nd max minus the 3rd, and 4th to 5th etc.. Until all numbers have been subtracted from their counterpart. The tricky part is that the numbers which need to be subtracted are in a different column, C11 to C90. </p>
<p>I'm basically trying to find the number of consecutive negative outcomes from column C using the 2 closest values from column A. </p>
<p>Any input would be greatly appreciated!!</p>

URGENT HELP! multiple nCr program : Okay, so I have to create a nCr program.
I need to allow the user to input the amount of nCr values they wish to calculate ( between 2 and 12 inclusive).
Then input the n and r values accordingly, making sure n is greater than r (n > r)
Afterwards i need to calculate and store the nCr value in an array and output the values
I wish to output the values in the format of a 2d array in the form of:
n | c | nCr
-----------
(without the grids)
So far my code is as follows:
public class nCr {
public static void main (String[] args) {
int nCrValues;
System.out.println("Enter amount of nCr values you wish to calculate: ");
nCrValues = input();
while ((nCrValues < 2) || (nCrValues > 10)){
System.out.println("Must be between 2 and 12 inclusive");
nCrValues = input();
}//END while
values(nCrValues);
}//END main
public static void values(int nCrValues){
//I know I need a loop to nCrValues to input 'n' and 'r' as an array, not sure how
int n, r;
System.out.println("Enter n value: ");
n = input();
System.out.println("Enter r value: ");
r = input();
calculatenCr(n,r);
}//END values
public static int calculatenCr(int n, int r){
int nCr;
nCr = fact(n) / (fact(n-r) * fact(t));
//store nCr values in array
}//END calculatenCr
public static int fact(int num){
int count;
int factor = 1;
for (count = 1; count <= num; count++){
factor *= count;
}//END for
return factor;
}//END fact
public static int input(){
int input;
Scanner sc = new Scanner(System.in);
input = sc.nextInt();
while (input < 0){
System.out.println("Must be a positive number.")'
input = sc.nextInt();
}//END while
return input;
}//END input
}//END CLASS
I need a method that outputs the arrays int the form
n | c | nCr |
-------------
how do i go by that and is all my coding correct so far?
Thank you very much

Why is this call to strstr not returning false? : <p>I've stumbled upon an issue with <a href="https://secure.php.net/manual/en/function.strstr.php" rel="noreferrer">strstr</a> in an old legacy codebase. There's lot of code, but basically the test case would come down to this:</p>
<pre><code>$value = 2660;
$link = 'affiliateid=1449&zoneid=6011&placement_id=11736&publisher_id=1449&period_preset=yesterday&period_start=2017-03-27&period_end=2017-03-27';
var_dump(strstr($link, $value));
</code></pre>
<p>I would expect this to return <code>false</code> since "2660" is not in the string however it returns <code>d=1449&zoneid=6011&placement_id=11736&publisher_id=1449&period_preset=yesterday&period_start=2017-03-27&period_end=2017-03-27</code>.</p>
<p>I realise that <code>$value</code> should be a string but still I don't understand why it's not casted to a string by PHP and why it's finding this number in the link.</p>
<p>Actually, if I try with <code>$value = '2660';</code> it returns <code>false</code> as expected.</p>

Converting httpClient answer to model objects [Angular 6] : <p>I have a question about the Angular 5 httpClient.</p>
<p><strong>This is a model class with a method foo() I'd like to receive from the server</strong></p>
<pre><code>export class MyClass implements Deserializable{
id: number;
title: string;
deserialize(input: any) {
Object.assign(this, input);
return this;
}
foo(): string {
// return "some string conversion" with this.title
}
}
</code></pre>
<p>This is my service requesting it:</p>
<pre><code>import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';
import { Observable } from 'rxjs';
import { MyClass } from './MyClass';
@Injectable({
providedIn: 'root',
})
export class MyClassService {
constructor(private http: HttpClient) {
}
getMyStuff(): Observable<MyClass[]> {
// this is where I hope to convert the json to instances of MyClass
return this.http.get<MyClass[]>('api/stuff')
}
}
</code></pre>
<h1>My Problem</h1>
<p>When I ask the service for instances of <code>MyClass</code> I get the data, but I cannot run <code>{{ item.foo() }}</code> in the template. Also, when I <code>console.log()</code> the <code>typeof</code> of an item where it is received in the service, I <strong>do no see</strong> instances of an object of <code>MyClass</code>.</p>
<p><strong>What am I doing wrong?</strong> I thought that writing <code>this.http.get<MyClass[]>('api/stuff')</code> would do the conversion.</p>
<p>Any hints? Thank you in advance!</p>

For inside a while condition to check multiple values : What I want to do is to check if an input value is a member, or not, of a struct that is a part of an array. Since I have multiple elements created, based on that struct, I have to search in each one the value of the member I want. If the value is there, the program should countinue, if not, the program must ask the input to search again. I have the do while loop so ask the input once but I dont know "what" to do whith the while condition in order for it to check all values.
if (numAlunos == 0)
printf("No data inserted yet!\n");
else
{
do
{
printf("Insert the number you want to search:\n");
number= validar_insert (2150001, 2169999);//check if the input is between this values
printf("That number doeste exist.\n");
printf("Enter another number.\n");
}while (for (i = 0; i < numAlunos; i++)//I tried something here
numero != vAlunos[i].numero)//didnt work

R: How to make a for loop for each vector in list : I have a list l, contains four vectors, each vector contains a number of elements, the vectors are not the same length.
l<- list(2:4,3:5,4:7,5:7)
for ( i in length(l)){
print(l)
}
[[1]]
[1] 2 3 4
[[2]]
[1] 3 4 5
[[3]]
[1] 4 5 6 7
[[4]]
[1] 5 6 7
I would like to add value 2 to all the elements of each vector in the list using for loop.
Maybe we need (**two for loops**) The external will be for the list and the internal will be for each vector of the list, I would like to obtain the following result :
[[1]]
[1] 4 5 6
[[2]]
[1] 5 6 7
[[3]]
[1] 6 7 8 9
[[4]]
[1] 7 8 9
**Please note that:** the original list contains 389 vectors, each vector contains not less than 45 elements.

How could I change string in a 2d list?(python) : In python..
How could I change a string in a 2d list to 'X'?
this is the sample code.
I want to change '9' to 'X'
example : cavityMap(['1112', '1912', '1892', '1234'])
result : 1112, 1X12, 18X2, 1234
this is my incomplete code.
def cavityMap(grid):
t = '9'
for i, j in enumerate(grid):
if i == 0:
continue
if i == len(grid)-1:

j = list(j)
for a, b in enumerate(j):

ReactiveSwift Simple Example : <p>I've read the <a href="https://github.com/ReactiveCocoa/ReactiveSwift" rel="noreferrer">documentation</a>, gone through their wonderful Playground example, searched S.O., and reached the extent of my <a href="http://www.urbandictionary.com/define.php?term=google-fu" rel="noreferrer">google-fu</a>, but I cannot for the life of me wrap my head around how to use ReactiveSwift.</p>
<p>Given the following....</p>
<pre><code>class SomeModel {
var mapType: MKMapType = .standard
var selectedAnnotation: MKAnnotation?
var annotations = [MKAnnotation]()
var enableRouteButton = false
// The rest of the implementation...
}
class SomeViewController: UIViewController {
let model: SomeModel
let mapView = MKMapView(frame: .zero) // It's position is set elsewhere
@IBOutlet var routeButton: UIBarButtonItem?
init(model: SomeModel) {
self.model = model
super.init(nibName: nil, bundle: nil)
}
// The rest of the implementation...
}
</code></pre>
<p>....how can I use ReactiveSwift to initialize <code>SomeViewController</code> with the values from <code>SomeModel</code>, then update <code>SomeViewController</code> whenever the values in <code>SomeModel</code> change?</p>
<p>I've never used reactive anything before, but everything I read leads me to believe this should be possible. <em>It is making me crazy.</em> </p>
<p>I realize there is much more to ReactiveSwift than what I'm trying to achieve in this example, but if someone could please use it to help me get started, I would greatly appreciate it. I'm hoping once I get this part, the rest will just "click".</p>

Is it possible to instantiate objects without constructor in Java : <p>When learning about String literals vs String objects, I came across the fact that there are 2 possible ways to instantiate a variable of type String</p>

String s1 = "text";
//Using constructor
String s2 = new String("text");
</code></pre>
<p>I was wondering if it is possible to somehow create an class and instead of instantiating it with a constructor, one could instantiate it using a literal</p>
<p>This is what I mean</p>
<pre><code>class Value {
int value;
//Some methods
}
Value val = 10; //Program automatically sets val.value = 10

Go Lang Error Handling Issue / Misunderstanding? : <p>Ok so I am using the following code, </p>

if err != nil {
log.Panic(err)
}
var user User
err := decoder.Decode(&user, r.PostForm)
if err != nil {
log.Panic(err)
}
</code></pre>
<p>Now when I try to run this code, I get the following error, </p>
<pre><code>no new variables on left side of :=
</code></pre>
<p>Now I know that this is due to using the same variable, in this case <code>err</code> but I have seen lots of examples where this is how other developers deal with error handling?</p>
<p>The way that I have been using is just to use <code>err1</code> and <code>err2</code> so I can build the code.</p>
<p>I have been over the docs but there is a lot to take in and must have missed how the <code>err</code> variable is being able to be re-used, or have I completely misunderstood something? </p>
<p>Thanks, </p>
