How do I format my output as a 4-by-4 matrix? : <pre><code>class By
{
public static void main(String args[]) throws InterruptedException {
String key = "Hello world";// plaintext
byte[] x = key.getBytes();
StringBuilder sb = new StringBuilder();
for (int i = 0; i < x.length; i++) {
int b = (int) x[i];
sb.append(Integer.toHexString(b));
}
System.out.println(sb.toString());
}
}
This program output is: 48656c6c6f20776f726c64
I need my output to be a 4-by-4 matrix as such:
1st row is:: 48 6f 72 00
2nd row is:: 65 20 6c 00
3rd row is:: 6c 77 64 00
4th row is:: 6c 6f 00 00
</code></pre>
<p>How do I write code for this in java?Please anyone show me the code to get my required output.</p>

How are variables in Java called that are set once but never again and are not final? : <p>I have several variables I need to set only once but never again after starting the application, such as SCREEN_WIDTH, ARRAY_X_LENGTH, TIME_APP_STARTED etc.</p>
<p>I do not declare these final because the software will decide what value to assign to them, not me manually. I capitalize the words though so that I can see that no other code will assign any value to it, only 1.</p>
<p>Is this a bad programming practice, and if yes, what should I do, I usually just have a file containing all these ''final'' variables and my flags, I do not like storing them locally.</p>

How to specify a Moment.js object annotation in Flow : <p>I'm currently learning Flow by applying it to an existing project and looking to annotate function parameters as a Moment.JS objects. </p>
<p>Using <a href="https://github.com/flowtype/flow-typed/" rel="noreferrer">flow-typed</a> I was able to install a library definition for Moment.JS which appears to have the type I'm looking for:</p>
<pre><code>declare class moment$Moment {
static ISO_8601: string;
static (string?: string, format?: string|Array<string>, locale?: string, strict?: bool): moment$Moment;
static (initDate: ?Object|number|Date|Array<number>|moment$Moment|string): moment$Moment;
static unix(seconds: number): moment$Moment;
static utc(): moment$Moment;
...
</code></pre>
<p>However when I try to annotate function parameters as Moment.JS objects, Flow fails to recognize them as such. In the following function <code>startDate</code> and <code>endDate</code> are Moment.JS date objects.</p>
<pre><code>const filterByDateWhereClause = (startDate: Moment, endDate: Moment): string => {...};
</code></pre>
<p>Flow gives the following error:</p>
<pre><code>const filterByDateWhereClause = (startDate: Moment, endDate: Moment): string =>
^^^^^^ identifier `Moment`. Could not resolve name
</code></pre>
<p>Is this even possible with Flow? Or do I need to duplicate the <code>type</code> for the Moment.JS object identical to the one in the library definition provided by flow-type? I'd prefer not to do this as the libdef is fairly lengthy. </p>
<p>For example:</p>
<pre><code>declare class Moment {
static ISO_8601: string;
static (string?: string, format?: string|Array<string>, locale?: string, strict?: bool): moment$Moment;
static (initDate: ?Object|number|Date|Array<number>|moment$Moment|string): moment$Moment;
static unix(seconds: number): moment$Moment;
static utc(): moment$Moment;
...
const filterByDateWhereClause = (startDate: Moment, endDate: Moment): string => {...};
</code></pre>
<p>What am I missing?</p>

How to mane an "in" statement inclusive-only in SQL : I have a subset of values that I want to evaluate against a row in SQL.
Select count(*) cnt from table_name c
where c.table_row in ('value 1','value 2', 'value 3')
and other statements;
This works fine as long as I only want to determine if "table_row" contains one of those three values.
What I want, however, is to determine if table_row contains **only** those values.
Is there any SQL statement that can perform an inclusive-only 'in' statement, so that for the "cnt" in the above query, I will only get a result if 'table_row' is in the set indicated by the query? | 0debug |

batch file code to detect 32-bit vs 64-bit office not working : <p>I'm trying to put together a batch file that would select the appropriate bit version of executables when run by the user. I found this code on stackoverflow:
<a href="https://stackoverflow.com/questions/35820375/batch-file-check-office-architecture-version">Batch file check office architecture version</a>
The problem is that it does not work when I paste it into a text file on my desktop and rename it .bat in my virtual machine that has 64-bit Office 2010 installed: it claims it is 32-bit, the default value set in the code. Not being adept in checking registry entries, I'm wondering if there isn't a ready-made version out there somewhere that actually works. I'm also wondering why there isn't a simple way to determine this. I would have thought that this is something that Microsoft would make easily accessible to developers. </p>

How to return multiple values in a function (Python)? : <p>So I'm new to coding and working my way through the Titanic data set from Kaggle. In the data frame there are columns labeled "Age" and "Sex." I want to make a new column that has 4 values that indicate for different things:
0: Male aged 16 or over
1: Female aged 16 or over
2: Male aged 15 or younger
3: Female aged 15 or younger</p>
<p>So far I've gotten this, but this just splits it up into 3 values, not the 4 I'm looking for.</p>
<pre><code>def person_detail(Person):
Age, Sex = Person
return 2 if Age < 16 else Sex
</code></pre>
<p>I then apply the function to the "Age" and "Sex" columns to get a new column. I know that you can't have two returns, but if it gets across what I am trying to accomplish, it would look something like the below.</p>
<pre><code>def person_detail(Person):
Age, Sex = Person
return 2 if Age < 16 and Sex == 0
return 3 if Age < 16 and Sex == 1 else Sex
</code></pre>
<p>Thanks in advance. For reference in the "Sex" column 0 is for male, and 1 is for female.</p>

Add a dash between running numbers and comma between non-running numbers : I would like to replace a set of running and non running numbers with commas and hyphens where appropriate.
Using STUFF & XML PATH I was able to accomplish some of what I want by getting something like 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 13, 15, 19, 20, 21, 22, 24.
WITH CTE AS (
SELECT DISTINCT t1.ORDERNo, t1.Part, t2.LineNum
FROM [DBName].[DBA].Table1 t1
JOIN Table2 t2 ON t2.Part = t1.Part
WHERE t1.ORDERNo = 'AB12345')
SELECT c1.SQ, c1.Part, STUFF((SELECT ', ' + CAST(LineNum AS VARCHAR(5))
FROM CTE c2
WHERE c2.SQ = c1.SQ
FOR XML PATH('')), 1, 2, '') AS [LineNums]
FROM CTE c1
GROUP BY c1.SQ, c1.Part
I would like to have 1-10, 13, 15, 19, 20-22, 24. | 0debug |
Sql Devloper - Use concat with GROUP BY function for COUNTING (Error ORA-00904) : I am working on a mock database for a project and
I have two tables: CUSTOMERS AND ORDERS
Both tables look like this
CUSTOMERS: custID, custLName, custFName, custAddress, custTown, custPostcode, custPhone, custEmail
And
ORDERS: orderID, orderDate, dispatchDate, custID (foreign key)
I am trying to generate a query that returns the full name and phone number of the customer who has made the most orders.
This is my query below however it is returning an error on the GROUP BY function stating ORA-00904: "CUSTOMER": invalid identifier

COUNT(DISTINCT o.custID) AS Orders_Placed
FROM CUSTOMERS b, ORDERS o
GROUP BY Customer
HAVING COUNT(DISTINCT o.custID) AND b.custID = o.custID

React.js How to render component inside component? : <p>I am stuck. I have several seperate components on seperate files. If I render them in main.jsx like following: </p>
<pre><code>ReactDOM.render(<LandingPageBox/>, document.getElementById("page-landing"));
ReactDOM.render(<TopPlayerBox topPlayersData={topPlayersData}/>, document.getElementById("wrapper profile-data-wrapper"));
ReactDOM.render(<RecentGamesBox recentGamesData={recentGamesData}/>, document.getElementById("history wrapper"));
</code></pre>
<p>Everything works fine, but I wonder if it is a good practice? Maybe it is possible to do something like there would be only one ReactDom.render like: </p>
<pre><code>ReactDOM.render(<LandingPageBox recentGamesData={recentGamesData} topPlayersData={topPlayersData}/>, document.getElementById("page-landing"));
</code></pre>
<p>I tried different kinds of variatons of LandingPageBox to somehow include those other two components, but had no luck. They sometimes rendered outside the page and so on. I thought it should look something like this:</p>
<pre><code>import React from 'react';
import RecentGames from '../RecentGames/RecentGames.jsx';
import TopPlayers from '../TopPlayers/TopPlayers.jsx';
import PageTop from './PageTop.jsx';
import PageBottom from './PageBottom.jsx';
class LandingPageBox extends React.Component {
render() {
return (
<body className="page-landing">
<PageTop>
<TopPlayers topPlayersData={this.props.topPlayersData} />
</PageTop>
<PageBottom>
<RecentGames recentGamesData= {this.props.recentGamesData}/>
</PageBottom>
</body>
);
}
}
export default LandingPageBox;
</code></pre>
<p>But this code only renders PageTop and PageBottom, without player or game components. </p>
<p>So my question would be, how to set up LandingPageBox file so that TopPlayers component would render inside PageTop component and RecentGames component would render inside PageBottom component? Thank you.</p>

Spark RDD: add field from RDD to other RDD : I'm using Pyspark and have to use RDDs (not dataframes) to do the following:
I have two RDDs, rdd1, containing more than 100 fields with names and rdd2, containing one field called "city". rdd1 and rdd2 have the same number of rows (same length).
rdd1 is like:
>Row(name="Jack",age=35,state="California",..)
Row(name"Jane", age=29,state="Florida",...)
...
rdd2 is like:
>Row(city="LA")
Row(city="Miami")
..
I would like rdd1 to become:
>Row(name="Jack", age=35, state="California",...,city="LA")
...

kubectl YAML config file equivalent of "kubectl run ... -i --tty ..." : <p>I've been using "kubectl run" with assorted flags to run Jobs interactively, but have recently outgrown what I can do with those flags, and have graduated to using YAML config files to describe my jobs.</p>

Kotlin Property: "Type parameter of a property must be used in its receiver type" : <p>I have the following simple Kotlin extension functions:</p>
<pre><code>// Get the views of ViewGroup
inline val ViewGroup.views: List<View>
get() = (0..childCount - 1).map { getChildAt(it) }
// Get the views of ViewGroup of given type
inline fun <reified T : View> ViewGroup.getViewsOfType() : List<T> {
return this.views.filterIsInstance<T>()
}
</code></pre>
<p>This code compiles and works fine. But, I want the function <code>getViewsOfType</code> to be a property, just like the <code>views</code>. Android Studio even suggests it. I let AS do the refactoring and it generates this code:</p>
<pre><code>inline val <reified T : View> ViewGroup.viewsOfType: List<T>
get() = this.views.filterIsInstance<T>()
</code></pre>
<p>But this code doesn't compile. It causes error: "Type parameter of a property must be used in its receiver type"</p>
<p>What is the issue here? Searching for help on this error doesn't seem to lead to an answer.</p>

breakpoint() using ipdb by default : <p>Is it possible that installing <em>ipdb</em> (or some other package written to do it explicitely) will result in <code>breakpoint()</code> running <em>ipdb</em> instead of <em>pdb</em> without binding <code>sys.breakpointhook()</code> to <em>ipdb</em>?</p>

Alpine Dockerfile Advantages of --no-cache Vs. rm /var/cache/apk/* : <p>When creating Dockerfiles using the Alpine image, I have often seen the use of the <code>apk --no-cache</code> and other times it is committed and instead I see <code>rm /var/cache/apk/*</code>.</p>
<p>I am curious to know making use of the <code>--no-cache</code> eliminates the need to later do a <code>rm /var/cache/apk/*</code>. I would also like to know if one style is favored over another.</p>

Impact of matrix sparsity on cblas_gemm and cublasSgemm : I have recently discovered that the performance of a cblas_sgemm call for matrix multiplication dramatically improves if the matrices have a "large" number of zeros in them. It improves to the point that it beats its cublas cousin by more than a 100 times. This could be most probably attributed to some **automatic detection of sparsity** and suitable format conversion by cblas_sgemm function.
Unfortunately, no such behavior is exhibited by its cuda counterpart i.e. cublasSgemm.
So, the question is, how can I get the same type of optimization on cublasSgemm for matrices that **may have** a large number of zeros.
And what technique does cblas_sgemm use to automatically adjust to sparse matrices?
Please, do not recommend cuSparse / CUSP etc because
1. I am not sure about the sparsity of input matrices beforehand
2. I am working on an iterative algorithm where for initial few iterations the matrices **may be** sparse but gradually become dense as time goes on.
Thanks in advance | 0debug |

Refresh Header after Login in Angular2 : <p>So I have a header component that displays either the User's name or "Sign In" depending on whether they are logged in or not. I also have a Login component that does all of the business logic of logging in. They currently do not have a parent / child relationship.</p>
<p>When the User logs in, the header does not refresh or change unless a full page refresh is done in the browser. I've been doing a lot of searching and reading online about different ways to do this. ngOnChanges, NgZone, ApplicationRef, and ChangeDetectorRef seem to be the most popular. I'm trying to implement this behavior in ChangeDetectorRef as this seems to be most relevant to my situation. However, I can't seem to find actual examples of how to use this. </p>
<p>I've coded it up but it does not seem to do anything. Any advice would be appreciated. I'd even accept that I'm taking the wrong approach and need to use another solution besides ChangeDetectorRef.</p>

Trying to run a C program on unix but a little confused with how input file is handled : I've tried to search for this but I'm having trouble figuring how to phrase my question so I figured I'd just ask here.
So I'm trying to run a C program in a unix environment and I have an input file as well. The teacher said we can run it by typing in "gcc programName ./a.out inputFile" or "gcc programName ./a.out inputFile > viewFile"
My question is how is this handled within the C program? Like is the input file being added as a parameter for main (or like its name or something) or is it acting like it's reading from system.in or something else? I'm getting a message saying that there's an error opening the input file and I have "int main(int argc, char* argv[])". If someone could explain what's going on and how the input file is handled, I'd really appreciate it. | 0debug |

My while loop conditions aren't evaluating them as I'm expecting : <p>I'm trying to make an input validation function that checks to see if cin fails (this works fine) and I'm trying to also make it check to see if it's within the min max range that I pass by variable to the function. </p>
<p>I've already tried messing around with different conditions and evaluating it by hand but it seems that either I'm missing some small minutia of the while loop or something total different.</p>
<pre><code>void isValid(int &value, std::string message, int min, int max) {
while(((std::cout << message) && !(std::cin >> value)) && ((value >= min) && (value <= max))) {
std::cout << "Error with input" << std::endl;
std::cin.clear();
std::cin.ignore(std::numeric_limits<int>::max(), '\n'); }
</code></pre>
<p>I expect the output of isValid(-1, "Enter the test score: ", 0, 100) to keep asking for a valid input, but it accepts it as is.</p>

How to get ComputeIfPresent working with Map within Map? : <p>When trying to alter a Map using the <strong>computeIfPresent()</strong> method I have trouble implementing this method when I use an innerMap. </p>
<p><strong>This works:</strong></p>
<pre><code>Map<String, Integer> mapOne = new HashMap<>();
mapOne.computeIfPresent(key, (k, v) -> v + 1);
</code></pre>
<p><strong>This doesn't work:</strong></p>
<pre><code>Map<String, Map<String, Integer>> mapTwo = new HashMap<>();
mapTwo.computeIfPresent(key, (k, v) -> v.computeIfPresent(anotherKey, (x, y) -> y + 1);
</code></pre>
<p>In the second example I get the following error message: "Bad return type in lambda expression: Integer cannot be converted to <code>Map<String, Integer></code>".
My IDE recognizes v as a Map. But the function doesn't work.</p>
<p>Apparently the method returns an Integer, but I fail to see how this differs from the first method with no Innermap. So far I haven't found a similar case online.</p>
<p>How can I get this to work?</p>

TemplateNotFound error when running simple Airflow BashOperator : <p>I'm trying to write our first Airflow DAG, and I'm getting the following error when I try to list the tasks using command <code>airflow list_tasks orderwarehouse</code>:</p>

Why does -Xrs reduce performance : <p>From IBM:</p>
<blockquote>
<p><strong>-Xrs</strong></p>
<p>Disables signal handling in the JVM.</p>
<p><strong>-Xrs</strong></p>
<p>Setting -Xrs prevents the Java™ run time environment from handling any internally or externally generated signals such as SIGSEGV and SIGABRT. Any signals that are raised are handled by the default operating system handlers. <strong>Disabling signal handling in the JVM reduces performance by approximately 2-4%, depending on the application.</strong></p>
<p><strong>-Xrs:sync</strong></p>
<p>On UNIX systems, this option disables signal handling in the JVM for SIGSEGV, SIGFPE, SIGBUS, SIGILL, SIGTRAP, andSIGABRT signals. However, the JVM still handles the SIGQUIT and SIGTERM signals, among others. As with -Xrs, the use of <strong>-Xrs:sync reduces performance by approximately 2-4%, depending on the application.</strong></p>
<p><strong>Note:</strong> Setting this option prevents dumps being generated by the JVM for signals such as SIGSEGV and SIGABRT, because the JVM is no longer intercepting these signals.</p>
</blockquote>
<p><a href="https://www-01.ibm.com/support/knowledgecenter/SSYKE2_7.0.0/com.ibm.java.aix.70.doc/diag/appendixes/cmdline/Xrs.html">https://www-01.ibm.com/support/knowledgecenter/SSYKE2_7.0.0/com.ibm.java.aix.70.doc/diag/appendixes/cmdline/Xrs.html</a></p>
<p>From my understanding, <code>-Xrs</code> is really used to prevent dumps from being generated when certain OS Signals are intercepted.</p>
<p>Since the JVM is no longer intercepting and handling these signals, it would stand to reason this would <em>increase</em> performance, not <em>decrease</em> it as claimed by IBM.</p>
<p>Why does <code>-Xrs</code> reduce performance?</p>

Pip install without progress bars : <p>In my Django application I have a circle.yml file that runs 'pip install -r requirements/base.txt'. When I push up code, and check the CircleCI logs when there is an error, its hard to get to because there are so many dependencies and as of pip6 they started showing progress bars for the installations. Because of that it get busy pretty quick. I read on pip's github page that a few people were requesting a flag to the install command to remove the progress bars, but continue to show everything else like exceptions. something like </p>
<p><code>pip install --no-progress-bar foo</code> </p>

Vue, is there a way to pass data between routes without URL params? : <p>I am looking how to pass data secretly between two separate components (not parent and child) without using URL params in my Vue2 app. This doesn't mean I am passing secrets but rather I just dont want the user to see it (only for UI considerations).</p>
<p>I know Vue has <a href="https://vuejs.org/v2/guide/components-props.html" rel="noreferrer">Props</a> but they are meant for passing data between parent and child component.
In my case, my URL will change but I don't want to pass data via visible params.</p>
<p>Someone claimed to use props without URL params <a href="https://dev.to/aligoren/passing-data-to-a-router-link-in-vuejs-2cb0" rel="noreferrer">here</a> but I haven't been able to reproduce a working solution (getting undefined each time).</p>
<p>I also checked out <a href="https://www.thepolyglotdeveloper.com/2017/11/pass-data-between-routes-vuejs-web-application/" rel="noreferrer">these</a> options but they are all using either URL or query params which as we know are visible.</p>
<p>An ugly solution would be to write the data to local storage and then read it there but this creates a lot of overhead and complexity (like what if I only want this data to be read once, etc).</p>
<p>Is there a more elegant solution to this problem?</p>
<p>Thanks!</p>

Refresh and fetch an entity after save (JPA/Spring Data/Hibernate) : <p>I've these two simple entities <code>Something</code> and <code>Property</code>.
The <code>Something</code> entity has a many-to-one relationship to <code>Property</code>, so when I create a new <code>Something</code> row, I assign an existing <code>Property</code>.</p>
<p><strong>Something:</strong></p>
<pre><code>@Entity
@Table(name = "something")
public class Something implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
@Column(name = "name")
private String name;
@Column(name = "owner")
private String owner;
@ManyToOne
private Property property;
// getters and setters
@Override
public String toString() {
return "Something{" +
"id=" + getId() +
", name='" + getName() + "'" +
", owner='" + getOwner() + "'" +
", property=" + getProperty() +
"}";
}
</code></pre>
<p><strong>Property:</strong></p>
<pre><code>@Entity
@Table(name = "property")
public class Property implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
@Column(name = "shape")
private String shape;
@Column(name = "color")
private String color;
@Column(name = "dimension")
private Integer dimension;
// getters and setters
@Override
public String toString() {
return "Property{" +
"id=" + getId() +
", shape='" + getShape() + "'" +
", color='" + getColor() + "'" +
", dimension='" + getDimension() + "'" +
"}";
}
}
</code></pre>
<p>This is the <code>SomethingRepository</code> (Spring):</p>
<pre><code>@SuppressWarnings("unused")
@Repository
public interface SomethingRepository extends JpaRepository<Something,Long> {
}
</code></pre>
<p>Through a REST controller and a JSON, I want to create a new <code>Something</code>:</p>
<pre><code>@RestController
@RequestMapping("/api")
public class SomethingResource {
private final SomethingRepository somethingRepository;
public SomethingResource(SomethingRepository somethingRepository) {
this.somethingRepository = somethingRepository;
}
@PostMapping("/somethings")
public Something createSomething(@RequestBody Something something) throws URISyntaxException {
Something result = somethingRepository.save(something);
return result;
}
}
</code></pre>
<p>This is the JSON in input (the <code>property</code> <code>id</code> 1 is an existing row in the database):</p>
<pre><code>{
"name": "MyName",
"owner": "MySelf",
"property": {
"id": 1
}
</code></pre>
<p>}</p>
<p>The problem is: after the method <code>.save(something)</code>, the variable <code>result</code> contains the persisted entity, but without the fields of field <code>property</code>, validated (they are <code>null</code>):</p>
<p>Output JSON:</p>
<pre><code>{
"id": 1,
"name": "MyName",
"owner": "MySelf",
"property": {
"id": 1,
"shape": null,
"color": null,
"dimension": null
}
}
</code></pre>
<p>I expect that they are validated/returned after the save operation.</p>
<p>To workaround this, I have to inject/declare the <code>EntityManager</code> in the REST controller, and call the method <code>EntityManager.refresh(something)</code> (or I have to call a <code>.findOne(something.getId())</code> method to have the complete persisted entity):</p>
<pre><code>@RestController
@RequestMapping("/api")
@Transactional
public class SomethingResource {
private final SomethingRepository somethingRepository;
private final EntityManager em;
public SomethingResource(SomethingRepository somethingRepository, EntityManager em) {
this.somethingRepository = somethingRepository;
this.em = em;
}
@PostMapping("/somethings")
public Something createSomething(@RequestBody Something something) throws URISyntaxException {
Something result = somethingRepository.save(something);
em.refresh(result);
return result;
}
}
</code></pre>
<p>With this workaround, I've the expected saved entith (with a correct JSON):</p>
<pre><code>{
"id": 4,
"name": "MyName",
"owner": "MySelf",
"property": {
"id": 1,
"shape": "Rectangle",
"color": "Red",
"dimension": 50
}
}
</code></pre>
<p>Is there an automatic method/annotation, with JPA or Spring or Hibernate, in order to have the "complete" persisted entity?</p>
<p>I would like to avoid to declare the EntityManager in every REST or Service class, or I want avoid to call the .findOne(Long) method everytime I want the new refreshed persisted entity.</p>
<p>Thanks a lot,
Andrea</p>

str_replace, gives me the wrong result Only when numerals are in it : <pre><code>//post data
$post = $_POST['username'];
//str replace
$print = str_replace([1,2,3,4,5], ['4A','6B','7C','2D','6F'], $post);
//prints result
echo "{\"username\":\"" . $print . "\"}";
</code></pre>
<p>str replace works fine when it's just alpha (example: <code>TEST!@#test = 7160767124452671607671</code> which is just perfect, but as soon as digits come into play things get messy <code>$print</code> should output <code>{"username":"4A6B7C2D6F"}</code> if input <code>12345</code> the current output is <code>{"username":"2DA6B7C2D6F"}</code></p>

<p>But tried again and got the same error. Sent a new email, and got the same answer. Retried and still can't launch...</p>
<p>Apparently there's no problem with my payment method or anything like that. Also tried to launch it in different regions, like n. virginia, oregon and são paulo. Got the same error.</p>
<p>Any ideas? Thanks!</p>
