Can you still use c++ in Xcode? : I want to learn c++ on my Mac computer. A lot of forums recommend using Xcode, but when I downloaded it I realized that it only has options for Swift or Objective c. Is there still a way to use c++ in Xcode? Or is Objective c or Swift very similar to c++?

How to populate a drop-down list from a SQL table in C# : <p>I have a table in my SQL database, and using MVC on a ASP.NET Core:</p>
<pre><code>CREATE TABLE [dbo].[ProgramVersion] (
[ID] INT IDENTITY (1, 1) NOT NULL,
[Ver] VARCHAR (10) NOT NULL,
[Released] DATETIME NOT NULL
);
</code></pre>
<p>Very simple. I have a scaffolded Edit.cshtml file, has a form for editing a records from a different table. I just want to use the records in the ProgramVersion table to populate an HTML select input (i.e. drop down list).</p>
<ol>
<li>How do I execute a simple query that gives me a result-set?</li>
<li>How do I iterate through the result-set and simply put the 'Ver' string value into the Options tags in the drop-down list?</li>
</ol>
<p>(In PHP, this is dead simple, but C# is really frustrating me.)</p>

How to use Domain Transform Edge-Preserving technique for Image Enhancement in Matlab : I am interested in using this Domain Transform Edge-Preserving Video filtering technique (http://inf.ufrgs.br/~eslgastal/DomainTransform/ - source code available there) for image enhancement in Matlab (2015a).
At around 3:12 on a 5-minute video (on the site linked above), they perform detail enhancement. I'm not sure how to use the filtered image to sharpen/deblur my original image.
I usually use:
H = padarray(2,[2 2]) - fspecial('gaussian' ,[5 5],2);
sharpened = imfilter(I,H);
to sharpen images, but I can't use imfilter with the filtered image from the edge-preserving technique (I've been testing with the normalized convolution filter from the source code) that I'm interested in.
Can anyone advise me on what I can do to make use of this filtered image for sharpening/deblurring? Providing a snippet of code would be appreciated as well if possible.

Strange expression I myself may have written: Java variable assignment syntax : Somewhere in my code today, I found that I had written the following line
JsonArray environmentJsonArray = new JsonArray(), playerJsonArray, teamJsonArray;
I am at a complete loss in understanding how this was even working. The basic question is this: What are the two variables on my RHS doing? I checked if I had declared them before. But I did not. The compiler still does not complain apparently indicating that the playerJsonArray and the teamJsonArray was being taken as fresh declarations. But then the declared variables are always on the LHS. Isn't that so? Has something changed in Java's basic syntax? Iam trying to go thru the specs to get to the bottom but just in case anyone has a quicker understanding please....

How do I debug a Python program (I am coming from a Ruby on Rails/JavaScript background)? : <p>I make web applications using Ruby on Rails as my backend. I use React and Flux on the frontend, which is JavaScript. I can fully use the debugging tools I need. I simply add the line of code "debugger" anywhere in my app, so that execution stops there. I use byebug gem in Rails. When the "debugger" line of code is executed on backend code, the debugging happens on the command line; when it happens in JavaScript code, the debugging happens in Chrome Dev Tools. In other words, I can work very quickly to debug.</p>
<p>What is the equivalent convenient debugging tool in Python? In other words, what should a person who can already program in general, and just wants to rapidly be able to debug in Python use? I am using Atom editor (like I use when I am making a web app).</p>

C# XML ignore < and > characters in a node : <p>I'm getting an xml document from a PHP script.</p>
<p>The XML schema looks something like this: </p>
<pre><code><Items>
<Item>
<ID>
123g8fdg
</ID>
<Name>
Michael
</Name>
<Note>
Some notes, for example a small xml snippet: <randomxml><...
</Note>
</Item>
</Items>
</code></pre>
<p>The Note node could have any value (even an XML snippet)
While trying on getting the following XML data back from the server, I noticed, that the C# <strong>LoadXML</strong> function fails if the Note is the following: </p>
<pre><code>"Finish date <= Start date + 1 year"
</code></pre>
<p>The "<" character breaks it up (I can see that even in the C# XML Visualizer while debugging)</p>
<p>Any ways to ignore any specific XML element in the notes section, so it doesn't interfere with the parser and basic structure?</p>

What's the proper scheme file extension? : <p>Files of the programming language Scheme are by convention either of the extension <code>.scm</code> or <code>.ss</code>.</p>
<p>I'm interested in what the history of these extensions is, and also in the proper use, though it seems the universal attitude is that it's just whatever you prefer and it doesn't matter, but maybe I'm wrong about that.</p>

When or why should I use a Mutex over an RwLock? : <p>When I read the documentations of <a href="https://doc.rust-lang.org/std/sync/struct.Mutex.html" rel="noreferrer"><code>Mutex</code></a> and <a href="https://doc.rust-lang.org/std/sync/struct.RwLock.html" rel="noreferrer"><code>RwLock</code></a>, the difference I see is the following:</p>
<ul>
<li><code>Mutex</code> can have only one reader or writer at a time,</li>
<li><code>RwLock</code> can have one writer or multiple reader at a time.</li>
</ul>
<p>When you put it that way, <code>RwLock</code> seems always better (less limited) than <code>Mutex</code>, why would I use it, then?</p>

Connect new celery periodic task in django : <p>It's not a question but help to those who will find that the declaration of periodic tasks described in celery 4.0.1 documentation is hard to integrate in django:
<a href="http://docs.celeryproject.org/en/latest/userguide/periodic-tasks.html#entries" rel="noreferrer">http://docs.celeryproject.org/en/latest/userguide/periodic-tasks.html#entries</a></p>
<p>copy paste celery config file <code>main_app/celery.py</code>:</p>
<pre><code>from celery import Celery
from celery.schedules import crontab
app = Celery()
@app.on_after_configure.connect
def setup_periodic_tasks(sender, **kwargs):
# Calls test('hello') every 10 seconds.
sender.add_periodic_task(10.0, test.s('hello'), name='add every 10')
# Calls test('world') every 30 seconds
sender.add_periodic_task(30.0, test.s('world'), expires=10)
# Executes every Monday morning at 7:30 a.m.
sender.add_periodic_task(
crontab(hour=7, minute=30, day_of_week=1),
test.s('Happy Mondays!'),
)
@app.task
def test(arg):
print(arg)
</code></pre>
<h3>Question</h3>
<p>But what if we use django and our tasks are placed in another app? With celery <code>4.0.1</code> we no longer have <code>@periodic_task</code> decorator. So let's see what we can do. </p>
<h3>First case</h3>
<p>If you prefer to keep tasks and their schedule close to each other:</p>
<p><code>main_app/some_app/tasks.py</code></p>
<pre><code>from main_app.celery import app as celery_app
@celery_app.on_after_configure.connect
def setup_periodic_tasks(sender, **kwargs):
# Calls test('hello') every 10 seconds.
sender.add_periodic_task(10.0, test.s('hello'))
@celery_app.task
def test(arg):
print(arg)
</code></pre>
<p>We can run <code>beat</code> in debug mode:</p>
<pre><code>celery -A main_app beat -l debug
</code></pre>
<p>and we will see that there's no such periodic task.</p>
<h3>Second case</h3>
<p>We can try to describe all periodic tasks in config file like this:</p>
<p><code>main_app/celery.py</code></p>
<pre><code>...
app = Celery()
@app.on_after_configure.connect
def setup_periodic_tasks(sender, **kwargs):
# Calls test('hello') every 10 seconds.
from main_app.some_app.tasks import test
sender.add_periodic_task(10.0, test.s('hello'))
...
</code></pre>
<p>The result is the same. But it will behave differently that you can see with manual debugging via pdb. In first example <code>setup_periodic_tasks</code> callback will not be fired at all. But in second example we'll get <code>django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet.</code> (this exception will not be print out)</p>

I'm using 64 Bit OS. How do I trick my browser that I'm using 32bit Operating System : Some websites detect my operating system architecture (eg. 32-bit / 64-bit OS) if I want to download something for Example Google Chrome website thinks that I'm using 64bit operating system and thus it downloads 'ChromeStandalone64.exe for me. If I want to download the 32bit, I need to be on the 32bit OS which I think the other way is to use another computer or setup Virtual Machine. How do I trick the browser that I use 32bit OS ?

Accessing global variable value in python : <pre><code>def definition():

<p>My question is why connection string always prints "test" in get_details(), though it is assigned with some value in load_config(), AM I missing something? </p>

Flutter: Initialising variables on startup : <p>I'm trying to use the values saved in the SharedPreferences to initialise several variables in my app. In Flutter, the SharedPreferences are asynchronous so it results in the variables initialising later on in the code which is creating problems with my app as some of the variables are null when the build method is called.</p>
<p>Here is a small test Flutter app I wrote to demonstrate this issue:</p>
<pre><code>import 'package:flutter/material.dart';
import 'package:flutter/cupertino.dart';
import 'package:path_provider/path_provider.dart';
import 'dart:io';
import 'dart:convert';
import 'package:shared_preferences/shared_preferences.dart';
class TestingApp extends StatefulWidget {
TestingApp() {}
@override
State<StatefulWidget> createState() {
// TODO: implement createState
return new _CupertinoNavigationState();
}
}
class _CupertinoNavigationState extends State<TestingApp> {
int itemNo;
@override
void initState() {
super.initState();
// SharedPreferences.getInstance().then((sp) {
// sp.setInt("itemNo", 3);
// });
SharedPreferences.getInstance().then((sp) {
print("sp " + sp.getInt("itemNo").toString());
setState(() {
itemNo = sp.getInt("itemNo");
});
});
print("This is the item number " + itemNo.toString());
}
@override
Widget build(BuildContext context) {
// TODO: implement build
print("item number on build " + itemNo.toString());
return new Text("Hello");
}
}
</code></pre>
<p>This is the result in the console:</p>
<pre><code>Performing full restart...
flutter: This is the item number null
flutter: item number on build null // build method being called and variable is null
Restarted app in 1 993ms.
flutter: sp 3
flutter: item number on build 3
</code></pre>
<p>You can see that when I tried to fetch the variable from SharedPreferences on startup, since SharedPreference is async, the itemNo is null. Then the app runs the build method and runs the build method on the itemNo = null which is resulting in crashes in the app.</p>
<p>Once it fetches the value from SharedPreferences, I call setState which then calls the build method again with the correct value. However, the initial call to build with the itemNo = null should not have happened.</p>
<p>I wish there was a synch method for SharedPreferences but it doesn't seem to exist. How do I run the app so that the variables are initialised properly in Flutter on startup?</p>
<p>I tried to solve this through using a synchronous method to initialise my variables by writing to a json file and then reading from it using the following short Flutter test app - to me, this appears to be overkill for saving a variable to initialise but I still gave it a try:</p>
<pre><code>import 'package:flutter/material.dart';
import 'package:flutter/cupertino.dart';
import 'package:path_provider/path_provider.dart';
import 'dart:io';
import 'dart:convert';
import 'package:shared_preferences/shared_preferences.dart';
class TestingApp extends StatefulWidget {
TestingApp() {}
@override
State<StatefulWidget> createState() {
// TODO: implement createState
return new _CupertinoNavigationState();
}
}
class _CupertinoNavigationState extends State<TestingApp> {
int itemNo;
File jsonFile;
String fileName = "items.json";
Directory dir;
bool fileExists = false;
void createFile(Map content, Directory dir, String fileName) {
// print("Creating file for category " + dir.path);
File file = new File(dir.path + "/" + fileName);
file.createSync();
fileExists = true;
file.writeAsStringSync(json.encode(content));
}
void writeToFile(int itemNo) {
// print("Writing to category file");
Map itemMap = new Map();
itemMap['item'] = itemNo;
if (fileExists) {
print("category file exists");
Map jsonFileContent = json.decode(jsonFile.readAsStringSync());
jsonFileContent.addAll(itemMap);
jsonFile.writeAsStringSync(json.encode(itemMap));
} else {
print("category File does not exists");
getApplicationDocumentsDirectory().then((Directory directory) {
dir = directory;
createFile(itemMap, dir, fileName);
});
}
}
fetchSavedItemNo() {
//load the currency from the saved json file.
getApplicationDocumentsDirectory().then((Directory directory) {
dir = directory;
jsonFile = new File(dir.path+ "/" + fileName);
fileExists = jsonFile.existsSync();
setState(() {
if (fileExists)
itemNo = json.decode(jsonFile.readAsStringSync())['item'];
print("fetching saved itemNo " +itemNo.toString());
if (itemNo == null) {
itemNo = 0;
}
});
return itemNo;
//else the itemNo will just be 0
});
}
@override
void initState() {
super.initState();
writeToFile(3);
setState(() {
itemNo = fetchSavedItemNo();
});
}
@override
Widget build(BuildContext context) {
// TODO: implement build
print("item number on build " + itemNo.toString());
return new Text("Hello");
}
}
</code></pre>
<p>I still have the results where the build method is being called before the variables are fully initialised which is causing app crashes.</p>
<pre><code>Performing full restart...
flutter: category File does not exists
flutter: item number on build null // the build method is called here
Restarted app in 1 894ms.
flutter: fetching saved itemNo 3

Why the put method of a JSONObject throws JSONException? : <p>I found few answers here on how to handle this exception, but there was no explanation why would this happen in the first place. I have the following code:</p>
<pre><code>for (Map.Entry<String, Double> entry: qosMap.entrySet()) {
JSONObject qosEntry = new JSONObject();
try {
qosEntry.put(entry.getKey(), entry.getValue());
} catch (JSONException ex) {
Logger.getLogger(JSONUtil.class.getName()).log(Level.SEVERE, null, ex);
}
}
</code></pre>
<p>The qosMap will never be empty, and the data in this map will always be valid. </p>
<p>What would be a case where the exception would thrown? Why do I need to have this extra code?</p>

Object creating and accessing inside a jframe code behind not work : <p>I have created a class called player and beginner (<code>public class Beginner extends Player</code>)</p>
<p>then I tried to access beginner from the main class. It worked.
screenshot down below.
<a href="https://i.stack.imgur.com/1vhfe.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/1vhfe.jpg" alt="Main object create and access"></a></p>
<p>Then I tried to create another object and access that object from the jframe. It allows me to create the object (<code>Beginner b1= new Beginner();</code>)
But does not allow to access that object. It says <em>identifier expected</em>.</p>
<p>Here's the screenshot inside the jframe.
<a href="https://i.stack.imgur.com/SALPl.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/SALPl.jpg" alt="Inside jframe"></a></p>
<p>How can I access through the jframe code behind?? What causes this ?</p>
<p>note: I am still a beginner to java. So please do not misunderstand me for asking these type of questions. Thank you ..!</p>

How does shallow compare work in react : <p>In <a href="https://facebook.github.io/react/docs/shallow-compare.html" rel="noreferrer">this documentation</a> of React, it is said that </p>
<blockquote>
<p>shallowCompare performs a shallow equality check on the current props and nextProps objects as well as the current state and nextState objects.</p>
</blockquote>
<p>The thing which I am unable to understand is If It shallowly compares the objects then shouldComponentUpdate method will always return true, as</p>
<blockquote>
<p>We should not mutate the states.</p>
</blockquote>
<p>and if we are not mutating the states then the comparison will always return false and so the shouldComponent update will always return true. I am confused about how it is working and how will we override this to boost the performance.</p>

what is the URL for JetBrains IDE plug-in repository? : <p>I thought this was a simple question, and still nothing works.</p>
<p>My first use-case is that the IDEA 15 (<em>Community</em>) appears to NOT have a repository configured. The *Plugins" tab in the <strong><em>Settings</em></strong> window / dialogue supports three operation aside from clicking on a plugin.:</p>
<ul>
<li><p>A button for [<code>Install JetBrains plugins</code>] ... This seems to be things downloaded with the installer or updates;</p></li>
<li><p>A [<code>Browse repositories plugins</code>] button ... which contains an "<em>empty</em>" list <br/>Further this dialogue contains two buttons for:</p>
<ul>
<li>A [<code>Manage repositories</code>] </li>
<li>[<code>HTTP proxy settings</code>] - Proxy configuration / setup</li>
</ul></li>
<li>An [<code>Install plugins from disk</code>] button ... which does what it says ;-)</li>
</ul>
<p>This question to ask is, what URL do I need to put into that:
* The [<code>Manage repositories</code>] </p>
<p>... list because the clean install had "<em>nada</em>" in that list.</p>
<p>The list of JetBrains plugins isn't the same as the list on the plugins repository web page:</p>
<ul>
<li><a href="https://plugins.jetbrains.com/" rel="noreferrer">https://plugins.jetbrains.com/</a></li>
</ul>
<p>In fact IDEA help pages recommend using the JetBrains repository... They do not seem to want to let one know the URL.</p>
<p>Also, what is the "Community" plugins URL? At the very least I'd like to verify that/<em>IF</em> the JetBrains plugin-list is updating (as there's no "update list" option to be seen).</p>
<p>Weird huh?</p>

At the moment I have succesfully binded the value of the slider to a textbox. I want to bind this same value to a variable within my code. Such as when the slide position is at 1.5. The calculation within the code will use the value 1.5. The variable which I required to be updated is the flslidervalue. But after my research online, I've learnt that I would need to use a double due to the fact that my slider numbers contain decimals.
Below is a snippet of my code with the relevant parts:
float flradius;
float flfactual;
float flfmax;
float flfos;
float slvalue;
private void btnCalculate_Click(object sender, RoutedEventArgs e)
{
flfactual = flfmax / flfos;
//output Flfmax back to form
txtFmax.Text = flfmax.ToString();
//output Flfactual back to form
txtFactual.Text = flfactual.ToString();
}
private void fosslider_ValueChanged(object sender,
RoutedPropertyChangedEventArgs<double> e)
{
txtSlider.Text = fosslider.Value.ToString();
Double slvalue = fosslider.Value.To
}
********************************************************************
XAML CODE
<Slider x:Name="fosslider" HorizontalAlignment="Left" Margin="403,258,0,0" VerticalAlignment="Top" Width="246" TickPlacement="BottomRight" Maximum="4" SmallChange="0.5" IsSnapToTickEnabled="True" ValueChanged="fosslider_ValueChanged" LargeChange="0.5" TickFrequency="0.5" />
<TextBox x:Name="txtSlider" HorizontalAlignment="Left" Height="23" Margin="431,310,0,0" TextWrapping="Wrap" VerticalAlignment="Top" Width="120"/>

Passing PHP value to a modal box : I want to pass a variable to a modal box I call on the same page but have not been able to do it.
Code to open modal box is as below
<li style="font-style:bold" title="rate on skill" class="skill_rating"><a data-toggle="modal" title="Add this item" class="open-AddBookDialog" href="#addBookDialog" data-id='<?php echo $skill_id2[$q]?>'><i class="fa fa-anchor" aria-hidden="true"></i> </a><?php echo $skilltemp2[$q2] ?></li>
Modal Box code as below
<div class="modal fade" id="addBookDialog" tabindex="-1" role="dialog" aria-labelledby="addBookDialog"><div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button>

Javascript before the closing body tag is as below
<script type="text/javascript">
$(document).on("click", ".open-AddBookDialog", function () {
var myBookId = $(this).data('id');
$(".modal-body #bookId").val( myBookId );

</script>
I saw a couple of answers at stackoverflow (example:http://stackoverflow.com/questions/10626885/passing-data-to-a-bootstrap-modal )but I have not been able to customize it for my requirement.
Pardon me if its is too simple. I am a noob

What kind of data format should I use for storing http request (very large data set)? : I would like to store http request data in AWS S3 and might do queries on these data by using AWS Athena/Spark/Nexus. What format is recommand in this case?
Choices are: JSON, CSV, TSV, Textfiles, Apache ORC, Apache Parquet, Compressed data.
Currently I am consider these 3 aspects: time for serialization/de-serialization, Query speed, space.
Any links might be helpful are welcomed! Thanks!

resizing window with gridBagLayout : <p>I am stuck on this a large amount of time and I dont know how to do it, despite seraching on Google lots of times. My problem is that, I have a program, with a container obtained from the JFrame. The thing is, I put my menuBar correctly, and just below my two buttons, but when I maximize the window, it appears a annoying white space that I dont want to be there. If i dont maximize the window, the components are fine placed, like this:</p>
<p><a href="https://i.stack.imgur.com/vBvzp.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/vBvzp.png" alt="enter image description here"></a></p>
<p>But when I maximize the window, it appears that annoying space (the one marked in red):</p>
<p><a href="https://i.stack.imgur.com/Ca3XN.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Ca3XN.png" alt="enter image description here"></a></p>
<p>And what I want is that the MenuBar and the buttons, stays stuck in that corner like the first picture. The code of the gridbaglayout of the menu bar and the buttons is the following:</p>
<pre><code>//MenuBar
gbc.fill = GridBagConstraints.HORIZONTAL;
gbc.weightx = 0.5;
gbc.weighty = 0.0; // si no ponemos esto la barra NO se queda anclada en la esquina
gbc.gridx = 0;
gbc.gridy = 0;
//gbc.anchor = GridBagConstraints.NORTHWEST;
//gbc.gridwidth = 2;
//gbc.gridheight = 1;
menuBar.setBorder(BorderFactory.createLineBorder(Color.black));
pane.add(menuBar, gbc);
//buttons
gbc.gridx = 0;
gbc.gridy = 1;
gbc.anchor = GridBagConstraints.LINE_START;//reseteamos su valor
gbc.gridwidth = GridBagConstraints.REMAINDER; // con esto indicamos que va a ser el ultimo componente de esa fila
gbc.weightx = 0.0;
gbc.weighty = 0.0;
gbc.fill = GridBagConstraints.NONE;
gbc.gridwidth = 2;
gbc.gridheight = 1;
panel.setBorder(BorderFactory.createLineBorder(Color.black)); //luego quitar es para ver lo que ocupaba el panel
pane.add(panel, gbc);

Visual Studio shows warning in vctmp file : <p>I have a C# project opened in visual studio. We are using TFS to manage our projects. In one source code file of the project I have configured a warning in the following way:</p>
<pre><code>#warning expand for all properties
</code></pre>
<p>When I compile my project the warning is shown in the error list twice. Once in the original file, and once in a file called <code>vctmp2984_94722.cs</code>. I can open the temporary file in visual studio and it has a previous state of the file.
Opening the file in explorer is not possible, cause the path of the temporary file points to a place that does not exist: C:\Users\developer\AppData\Local\Temp\TFSTemp\vctmp2984_94722.cs</p>
<p>Does anybody nows how to solve this?</p>

Not able to do proper path monitoring or querying with Firebase and ElasticSearch (with Flashlight) : <p>I'm trying to integrate ElasticSearch wit Firebase. I'm using the <a href="https://github.com/firebase/flashlight" rel="nofollow">Flashlight integration</a> from Firebase to set ut all up. I have deployed the code to Heroku as described in the Github repo linked above.</p>
<p>It works in the sense that when I insert a query objet to <code>/search/request/</code> I get a <code>/search/response</code> result. But the results are a bit messy, not correct. But I can't figure out what is wrong.</p>
<p>This is what is defined in <code>config.js</code> where I define the paths to monitor:</p>
<pre><code>/** Paths to Monitor
*
* Each path can have these keys:
* {string} path: [required] the Firebase path to be monitored, for example, `users/profiles`
* would monitor https://<instance>.firebaseio.com/users/profiles
* {string} index: [required] the name of the ES index to write data into
* {string} type: [required] name of the ES object type this document will be stored as
* {Array} fields: list of fields to be monitored and indexed (defaults to all fields, ignored if "parser" is specified)
* {Array} omit: list of fields that should not be indexed in ES (ignored if "parser" is specified)
* {Function} filter: if provided, only records that return true are indexed
* {Function} parser: if provided, the results of this function are passed to ES, rather than the raw data (fields is ignored if this is used)
*
* To store your paths dynamically, rather than specifying them all here, you can store them in Firebase.
* Format each path object with the same keys described above, and store the array of paths at whatever
* location you specified in the FB_PATHS variable. Be sure to restrict that data in your Security Rules.
****************************************************/
exports.paths = [{
path: "users",
index: "firebase",
type: "user"
}, {
path: "messages",
index: "firebase",
type: "message",
fields: ['msg', 'name'],
filter: function(data) {
return data.name !== 'system';
}
}];
</code></pre>
<p>This is the structure of the user node in Firebase (it's located at the root).</p>

why does the value of this code always return true and not false/else statement (for a password checker program)? : This piece of code uses isdigit() and islower() which both check if a string includes only numbers(isdigit) or only lowercase letters(islower). If the string given through password contains only numbers or lowercase letters the value should return true and print "only numbers" if the string only contains numbers or "only letters" if the string contains only letters, which it does, however if the password contains numbers and letters for example "12345qwerty" it should return the value false right and go onto the elif statement to check if it has a number or letter included to say add 5 points and if it still doesn't then it will say try again but it doesn't it stil returns the value as rue and print the if statements argument which doesnt make sense since the password "12345qwerty" contain both letters and numbers and should be returned as false. could someone explain why its doing this and solution's with it. Thank you.
import re
password = input("")
if password.isdigit():
print("only numbers ")
elif re.search("[1-9]", password):
print("thats 5 points")
else:
print("try again")
if password.islower():
print("only letters ")
elif re.search("[a-z]", password):
print("thats 5 points")
else:
print("try again")

Veritcal histogram without arrays - java : I have to write an app which will get 3 numbers from user and create a histogram.
F.g:
Input: 2, 4, 3
Output:
*
**
***

It's not that easy, because I can't use any array. I had an idea to find the biggest number and then create the loop
for(int i = max; i > 0; i--)
but I have no idea what to put in the loop.

How to secure a Firebase database if I don't want users to have a login? : <p>I want to store some user information without any authentication from Android. The information is not important, doesn't need to be secure and the users don't need to have a login. The only way I've figured out how to do it is to use these rules:</p>
<pre><code>{
"rules": {
".read": "auth != null",
".write": "auth != null"
}
}
</code></pre>
<p>But firebase tells me that is not secure and I should secure it. So how can I secure it? I am using <code>signInAnonymously()</code> on the <code>FirebaseAuth</code> instance. </p>
