NullPointerException in GridWorld : <p>I know this type of question has been asked before, but in my case my code is different and I have no idea where this NullPointer is coming from.</p>
<p>I am recreating Conway's Game of Life using GridWorld, and I am getting this NullPointerException. I have no clue where it is coming from because looking at the code, it should be working. The act method of this code runs every time GridWorld moves forward a "step". In the first step, the cells are removed and born fine. However, when the second iteration comes, there is a NullPointerException when I try to remove a cell from the grid, when there is a cell there.</p>
<pre><code>int count=0;
public void act() {
if (!isDying) {
count++;
for (Location loc : this.getGrid().getOccupiedLocations()) {
int nCount = this.getGrid().getOccupiedAdjacentLocations(loc).size();
if (nCount == 2 || nCount == 3) {
//Do nothing
} else if (nCount == 1 || nCount == 0) {
//Die of loneliness
if(!deathRow.contains(loc)) {
deathRow.add(loc);
}
} else if(nCount>=4) {
//Die of overcrowding
if(!deathRow.contains(loc)) {
deathRow.add(loc);
}
}
candidateNeighbors = this.getGrid().getEmptyAdjacentLocations(loc);
for (Location candidate : candidateNeighbors) {
int cCount = this.getGrid().getOccupiedAdjacentLocations(candidate).size();
if(cCount==3){
if(!birthList.contains(candidate)) {
birthList.add(candidate);
}
}
}
}
isDying=true;
}
else{
count++;
System.out.println("\nAct: "+count);
if(deathRow.size()!=0) {
for (Location death : deathRow) {
System.out.println("Death List: "+deathRow);
System.out.println("Cell to Die: "+death);
this.getGrid().get(death).removeSelfFromGrid();
}
deathRow.clear();
}
if(birthList.size()!=0) {
for (Location birth : birthList) {
System.out.println("Birth List: "+birthList);
System.out.println("Cell to be born: "+birth);
Cell newCell = new Cell();
newCell.putSelfInGrid(this.getGrid(), birth);
}
birthList.clear();
}
isDying=false;
}
}
</code></pre>
<p>When I run the code, this is my console output:</p>
<pre><code>Act: 2

Android - Show BottomSheetDialogFragment above Keyboard : <p>I'm trying to show a <code>BottomSheetDialogFragment</code> with a few <code>EditText</code> fields for the user to enter information. I want to show it directly above the keyboard, but it keeps covering up the contents.</p>
<p>This is what happens when I bring up the <code>BottomSheetDialogFragment</code>, you can see it's selecting <code>Card Number</code> <code>EditText</code>, but covering the other content.</p>
<p><a href="https://i.stack.imgur.com/L6QiC.png" rel="noreferrer"><img src="https://i.stack.imgur.com/L6QiC.png" alt="BottomSheetDialogFragment covering up content"></a></p>
<p>Ideally, this is what I'm looking for, you can see both <code>EditTexts</code>, and the padding of the View.</p>
<p><a href="https://i.stack.imgur.com/Htx0O.png" rel="noreferrer"><img src="https://i.stack.imgur.com/Htx0O.png" alt="BottomSheetDialogFragment not covering up content"></a></p>
<p>I've tried a lot of solutions revolving around <code>windowSoftInputMode</code>, but nothing seems to work. I've set it to <code>adjustResize</code> for the parent <code>Activity</code> and the actual <code>BottomSheetDialogFragment</code> via</p>
<p><code>
dialog.window.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE)
</code></p>
<p>And I've also tried modifying my layout, changing it from a <code>FrameLayout</code>, to a <code>ScrollView</code> to a <code>CoordinatorLayout</code> to see if that had any effect on the position of the layout, but nothing seems to work.</p>
<p>If anyone knows how to accomplish this, that would be greatly appreciated, thank you.</p>

A problematic if statement in Javascript : I have an if statement with two conditions and an or operator between them, it evaluates to be true after only one condition.
because I used the || operator it checks the first condition and if it is true it will go into the if statement without checking the second one.
if (checkPassword() == true || checkUserName() == true)
evenet.preventDefault();
I expect it to go into the checkUserName function because there are crucial things in it that needs to be done, I can do it the long way but it will be cool if there is a way to make the if statement check the second condition even though it has the || operator and that's how programming works ( as far as I know)

What is the argument should an Indian trader pass to both these functions in R? : There is a documentation for backtesting in R in GitHub(https://timtrice.github.io/backtesting-strategies/).
I have a query in two lines of code mentioned in this document.
##First line
> `Sys.setenv(TZ = "UTC")`
##Second line
> `currency('USD')`
As you can see, the first line sets - system time to the US and the second line - sets the currency in which trading is occurring to the US. I am an Indian Trader and my job is to do back-testing with equity data for Indian companies. I use quantstrat and quantmod packages along with its dependencies. The data is downloaded from Yahoo Finance through R platform.
- What is the argument should an Indian trader pass to both these
functions(Sys.setenv and currency)???. The currency of Indian market
is INR(Indian Nation Rupees) and the time of India is GMT+5:30

Support Multiple Label Printers : <p>We develop a desktop business application where we are going to add support to label printing.</p>
<p>As there are lots of different printer makes and models out there, I want to discuss here what would be the best approach to manage all these different models/makes.</p>
<p>Considering some printers use the windows spool (Brother, Dymo, etc) and other ones uses ZPL, EPL, etc. (Zebra, Argox, etc) or anything else, what would be the best approach to support different models.</p>
<p>I was thinking about getting the printer description after the user selects its desired printer, and from them, my code will look for the specific implementation and if does not find it, alert the user.</p>
<p>However, the user can change label description if I understand. </p>
<p>How can I manage this?</p>
<p>Thank you,</p>
<p>Igor.</p>

How would I extract a .GZ file from CMD using only commands built in to windows/java/portable program : <p>My team is working with .GZ files and they need some way, ANY WAY, to extract a .GZ from command line. It can be using Java commands (as long as it can be run from CMD). If it can be done with a third party PORTABLE executable that is fine as well, as long as it's free. I don't have much to go on here so I'm giving the most information as I can. Basically in a nutshell:</p>
<ul>
<li>I need to open .gz files</li>
<li>It has to be done through a Batch file (CMD)</li>
<li>It cannot use anything that must be installed apart from Java.</li>
<li>It can use a portable EXE (toggleable from CMD)</li>
</ul>
<p>Thanks a bunch, sorry it is low on information!
-Lucas E. Executive Programmer for EDG</p>
<p><em>Side note: This goes along with minecraft, so, I know I can somehow make and extract them since minecraft saves it's log files in .gz format.</em> If the item I need comes with minecraft I can work with that.</p>

Remove a service in ASP.Net Core Dependency Injection : <p>In an Asp.Net MVC Core (early versions, versions 1.0 or 1.1), dependency injection bindings are configured as follow in the Startup.cs class :</p>
<pre><code>public class Startup
{
public void ConfigureServices(IServiceCollection services)
{
services.AddScoped<IMyService, MyService>();
// ...
}
}
</code></pre>
<p>In my applications, I usually have a base Startup class, where generic bindings are defined as a sequence of these lines :</p>
<pre><code>public abstract class BaseStartup
{
public virtual void ConfigureServices(IServiceCollection services)
{
services.AddScoped<IMyService1, MyService1>();
services.AddScoped<IMyService2, MyService2>();
}
}
</code></pre>
<p>Then in my application, I inherit the startup class, and inject other services as well :</p>
<pre><code>public class Startup : BaseStartup
{
public override void ConfigureServices(IServiceCollection services)
{
base.ConfigureServices(services);
services.AddScoped<IMyService3, MyService3>();
services.AddScoped<IMyService4, MyService4>();
}
}
</code></pre>
<p>I now wonder : how can I kind of 'override' a previous binding ?
I would like, for instance, to either remove, or modify a binding defined in the base class, like :</p>
<pre><code>services.Remove<IMyService1>(); // Doesn't exist
services.AddScoped<IMyService1, MyBetterService1>();
</code></pre>
<p>Or simply update the binding :</p>
<pre><code>services.AddScoped<IMyService1, MyBetterService1>(replacePreviousBinding: true); // Doesn't exist either !
</code></pre>
<p>Is there a way to do that ? Or maybe simply declaring a new binding with the same interface as a previously defined binding will override that binding ?</p>

Android sqlite get largest value of a row among multiple entries : My question is similar to the following post:
https://stackoverflow.com/questions/35565309/find-largest-value-among-repeated-entries-in-an-sql-table
but it is for mysql and and I cannot understand how it translates in sqlite.
I want to get the max value of `pages` from my table `metadata` with multiple `file_ids` and multiple entries
My table with the two columns I am interested in.
`file_id pages
1 2
1 5
2 10
3 20
4 12
4 1
5 4
6 5
6 14
7 12`
What I am looking for is
`file_id pages
1 5
2 10
3 20
4 12
5 4
6 14
7 12`
I am trying to make a query but don't know how
String[]cols = {"file_id","pages"};
String groupBy = {"pages"};
all others params are null
that's as far as I can think.
What will be the query like. Please help.

Dependencies are failed to resolve when migrated from Spring Boot 1.5.10 to 2.0.0 : <p>So, I migrated my basic application from Spring Boot 1.5.10 to 2.0.0. I am using Gradle and before the migration, I always excluded version numbers of the artifacts of the compile dependencies. After the migration, gradle build task started to throw an error like this:</p>
<pre><code>BUILD FAILED in 0s
2 actionable tasks: 1 executed, 1 up-to-date
During the build, one or more dependencies that were declared without a version failed to resolve:
org.springframework.boot:spring-boot-starter-data-rest:
org.springframework.boot:spring-boot-starter-web:
org.springframework.boot:spring-boot-starter-data-jpa:
Did you forget to apply the io.spring.dependency-management plugin to the llutrackr project?
</code></pre>
<p>My <code>build.gradle</code> (I excluded the irrelevant parts):</p>
<pre><code>buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath("org.springframework.boot:spring-boot-gradle-plugin:2.0.0.RELEASE")
}
}
dependencies {
compile("org.springframework.boot:spring-boot-starter-data-rest")
compile('org.springframework.boot:spring-boot-starter-data-jpa')
compile('org.springframework.boot:spring-boot-starter-web')
}
</code></pre>
<p>After I add version numbers to the corresponding dependencies, then the problem is solved. Why is this change necessary to build Spring Boot 2.0 projects with gradle? Even spring guides don't include artifact version numbers. <a href="https://spring.io/guides/gs/rest-service/" rel="noreferrer">An example</a></p>

how to start the second activity from the first, directly, not through a button : All the textbooks/guides start the second activity via click a button.
I thought I can start it directly by just removing the button codes.
Obvious I was wrong. Below code reports "Unfortunately, the xxxx has stopped".
So, my question: ow to start the second activity from the first?
(I can't believe I am the only newbies need to seek help on this while others figured it out by themselves for I can not google the similar question)
Thanks.

@Override

super.onCreate(savedInstanceState);

Zero-cost properties with data member syntax : <p>I have (re?)invented this approach to zero-cost properties with data member syntax. By this I mean that the user can write:</p>
<pre><code>some_struct.some_member = var;
var = some_struct.some_member;
</code></pre>
<p>and these member accesses redirect to member functions with zero overhead.</p>
<p>While initial tests show that the approach does work in practice, I'm far from sure that it is free from undefined behaviour. Here's the simplified code that illustrates the approach:</p>
<pre><code>template <class Owner, class Type, Type& (Owner::*accessor)()>
struct property {
operator Type&() {
Owner* optr = reinterpret_cast<Owner*>(this);
return (optr->*accessor)();
}
Type& operator= (const Type& t) {
Owner* optr = reinterpret_cast<Owner*>(this);
return (optr->*accessor)() = t;
}
};
union Point
{
int& get_x() { return xy[0]; }
int& get_y() { return xy[1]; }
std::array<int, 2> xy;
property<Point, int, &Point::get_x> x;
property<Point, int, &Point::get_y> y;
};
</code></pre>
<p>The test driver demonstrates that the approach works and it is indeed zero-cost (properties occupy no additional memory):</p>
<pre><code>int main()
{
Point m;
m.x = 42;
m.y = -1;
std::cout << m.xy[0] << " " << m.xy[1] << "\n";
std::cout << sizeof(m) << " " << sizeof(m.x) << "\n";
}
</code></pre>
<p>Real code is a bit more complicated but the gist of the approach is here. It is based on using a union of real data (<code>xy</code> in this example) and empty property objects. (Real data must be a standard layout class for this to work).</p>
<p>The union is needed because otherwise properties needlessly occupy memory, despite being empty.</p>
<p>Why do I think there's no UB here? The standard permits accessing the common initial sequence of standard-layout union members. Here, the common initial sequence is empty. Data members of <code>x</code> and <code>y</code> are not accessed at all, as there are no data members. My reading of the standard indicate that this is allowed. <code>reinterpret_cast</code> should be OK because we are casting a union member to its containing union, and these are pointer-interconvertible.</p>
<p>Is this indeed allowed by the standard, or I'm missing some UB here?</p>

Type 'Any' Has no Subscript Members in xcode 8 Swift 3 : <p>My App is supposed to go to a specific location to pull down the website it needs to load. In 2.3 it worked like a charm, but since I've updated xcode (which I don't have a ton of experience in) it is giving me the error "type 'Any' has no subscript members" and highlighting the "json" right before line three</p>
<pre><code>...Retriever = json["WEB"]...

<p>this is the code related to it.</p>

if let name = website["URL"] as? String {
self.loadAddressURL(name)

<p>I feel like I am missing something small. If there is a better way to do this, I would love suggestions. The URL returns this JSON</p>
<pre><code>{
"WEB" : [

"URL" : "http://www.google.com"

What source control is available for PHP / SQL projects : <p>I am working with a PHP web application that has a MS SQL back end. The development copy is hosted on a Windows server.</p>
<p>There will be a few developers joining me on the project, and I need some sort of source control so that (obviously) we don't over-write each other's work. But since a PHP/SQL project has to be run from the server, we can't each work with local copies and then push the updates to the server...we all have to be working on the server itself.</p>
<p>So I have three questions:</p>
<ol>
<li><p>My initial thought was a simple check-in, check-out system, which should be ok for our small team of 3-4 programmers. So, what is (currently) a good program for that?</p></li>
<li><p>I also thought about each developer having his own folder in the wwwroot folder, his own full copy of the program, then pushing updates to a master copy, also on the same server. Is there a good program for doing that (file merging and conflict management)?</p></li>
<li><p>Which method do you think would be better?</p></li>
</ol>

Why is there a need to specify distinct? I thought that the Id being a primary key was enough to avoid Duplicate results. Thanks in advance.

keras vs. tensorflow.python.keras - which one to use? : <p>Which one is the recommended (or more future-proof) way to use Keras?</p>
<p>What are the advantages/disadvantages of each?</p>
<p>I guess there are more differences than simply saving one <code>pip install</code> step and writing <code>tensorflow.python.keras</code> instead of <code>keras</code>.</p>

Calling an async method from component constructor in Dart : <p>Let's assume that an initialization of MyComponent in Dart requires sending an HttpRequest to the server. Is it possible to construct an object synchronously and defer a 'real' initialization till the response come back?</p>
<p>In the example below, the _init() function is not called until "done" is printed. Is it possible to fix this?</p>
<pre><code>import 'dart:async';
import 'dart:io';
class MyComponent{
MyComponent() {
_init();
}
Future _init() async {
print("init");
}
}
void main() {
var c = new MyComponent();
sleep(const Duration(seconds: 1));
print("done");
}
</code></pre>
<p><strong>Output</strong>:</p>
<pre><code>done
init

Angular 8 : Merging two objects in an array : <p>I have a couple of objects inside of an array :</p>
<pre><code>array1 =[{name : "Cena", age : 44},{job : "actor", location : "USA"}]
</code></pre>
<p>is there a way for me to merge these two objects to get something like : </p>
<pre><code>array2 =[{name : "Cena", age : 44, job : "actor", location : "USA"}]
</code></pre>
<p>I tried looping through the elements but it is not a good option if the object is a big one, I guess. Any good solution using typescript?</p>

take more time filter from 3 crore records in hive table compare to mysql(Approx 3 GB Size) : I am working with `hive` table to execute one of sql to fetch some records from 3 crore records but it is taking more time to execute with map reduce process (300 seconds) and `mysql` fetch this information in less 1 seconds. Could you suggest me why `hive` take more time or any other way to fetch quick response.
As I am using `Ambari` Cluster with `Tez` engine. Could you guide me for this. As I am confusing for moving database on `hadoop`. Let me know your concerns.
Thanks in advance.

how to sort partition in apache spark : Hi i have a used the dataframe which contains the query
df : Dataframe =spark.sql(s"show Partitions $yourtablename")
now the number of partition changes everyday as it runs everyday
the main concern is i need to fetch the latest partition.
supoose i get the partition for a random table for a particular day
like
year=2019/month=1/day=1
year=2019/month=1/day=10
year=2019/month=1/day=2
year=2019/month=1/day=21
year=2019/month=1/day=22
year=2019/month=1/day=23
year=2019/month=1/day=24
year=2019/month=1/day=25
year=2019/month=1/day=26
year=2019/month=2/day=27
year=2019/month=2/day=3
Now of you can see have as the functionality that it sorts the partition after day=1 comes day=10 so this creates a problem as need to fetch the latest partition.
I have managed to get the partition by using
val df =dff.orderby(col("partition").desc.limit(1)
but this gives me the tail -1 partition and not the latest partition .
How can i get the latest partition from the tables overcoming hives's limitation of arranging partition.
so suppose in the above example
i need to pickup
year=2019/month=2/day=27
and not year=2019/month=2/day=3
which is the last partition in the table

<li>a user manually triggering the build using the 'build now' button in the UI. </li>

Using Import In NodeJS server : <p>At the moment all my module in my nodejs server are imported as require() ie:</p>

Assigning Typescript constructor parameters : <p>I have interface :</p>
<pre><code>export interface IFieldValue {
name: string;
value: string;
}
</code></pre>
<p>And I have class that implements it :</p>
<pre><code>class Person implements IFieldValue{
name: string;
value: string;
constructor (name: string, value: string) {
this.name = name;
this.value = value;
}
}
</code></pre>
<p>after reading <a href="https://www.stevefenton.co.uk/2013/04/stop-manually-assigning-typescript-constructor-parameters/" rel="noreferrer">this post</a> I've thinking about refactoring :</p>
<pre><code>class Person implements IFieldValue{
constructor(public name: string, public value: string) {
}
}
</code></pre>
<p>Question : In first class I have fields which by default should be as <code>private</code>. In second sample I can only set them as <code>public</code>. Is it all correct or my understanding of default Access modifiers in TypeScript? </p>
