How to geocode address by google maps iOS API? : <p>I found one way to send request:</p>
<blockquote>
<p>A Google Maps Geocoding API request takes the following form:</p>
<p><a href="https://maps.googleapis.com/maps/api/geocode/outputFormat?parameters" rel="noreferrer">https://maps.googleapis.com/maps/api/geocode/outputFormat?parameters</a>
where outputFormat may be either of the following values:</p>
<p>json (recommended) indicates output in JavaScript Object Notation
(JSON); or xml indicates output in XML To access the Google Maps
Geocoding API over HTTP, use:</p>
</blockquote>
<p>But it's really inconvenient, is there any native way in swift?</p>
<p>I looked into GMSGeocoder interface and only reverse geocoding can be done by it's API.</p>

Validate multiple textbox in javascript? : i want to validate name, email,zip code on button click, but it's showing only last error msg, not specific to the filed, i m wirtting this code in javascript & jquery. anyone please help us . thanks | 0debug |
How do i alter my Current code to read directly from the IDR register : <p>Modify the code for <strong>ReadJoystick()</strong> to read the <strong>IDR register</strong> directly for the ports associated
with the joystick inputs. The aim is to minimise the number of reads to the register. The code in
the template makes an individual call for each of the inputs pins, even though some of the pins are
on the same ports.
You can refer to the HAL code for inspiration. Use the defined values in the HAL for addressing
registers rather than creating new ones.</p>
<p>Example Code Given to Me</p>
<pre><code>GPIO_PinState HAL_GPIO_ReadPin(GPIO_TypeDef* GPIOx, uint16_t GPIO_Pin)
{
GPIO_PinState bitstatus;
/* Check the parameters */
assert_param(IS_GPIO_PIN(GPIO_Pin));
if ((GPIOx->IDR & GPIO_Pin) != (uint32_t)GPIO_PIN_RESET)
{
bitstatus = GPIO_PIN_SET;
}
else
{
bitstatus = GPIO_PIN_RESET;
}
return bitstatus;
</code></pre>
<p>}</p>
<hr>
<p><strong>Code I require to Alter</strong></p>
<p>// REPLACE THE FOLLOW CODE WITH YOUR SOLUTION </p>
<pre><code>uint8_t
ReadJoystick ()
{
uint8_t JoystickPosition = 0;
// Get current joystick value
if (HAL_GPIO_ReadPin (JOY_A_GPIO_Port, JOY_A_Pin) == GPIO_PIN_RESET)
{
JoystickPosition = 'L';
}
else if (HAL_GPIO_ReadPin (JOY_B_GPIO_Port, JOY_B_Pin) ==
GPIO_PIN_RESET)
{
JoystickPosition = 'U';
}
else if (HAL_GPIO_ReadPin (JOY_C_GPIO_Port, JOY_C_Pin) ==
GPIO_PIN_RESET)
{
JoystickPosition = 'D';
}
else if (HAL_GPIO_ReadPin (JOY_D_GPIO_Port, JOY_D_Pin) ==
GPIO_PIN_RESET)
{
JoystickPosition = 'R';
}
else if (HAL_GPIO_ReadPin (JOY_CTR_GPIO_Port, JOY_CTR_Pin) ==
GPIO_PIN_RESET)
{
JoystickPosition = 'C';
}
return JoystickPosition;
}
</code></pre>
<p>So I Understand that my current code is reading each pin although i've been asked to alter this to read directly from the IDR register. I'm really new to embedded systems programming and just looking for someone to guide me with altering this code</p>

Prevent "use strict" in typescript? : <p>When trying to load my app on an iOS device I get the following error;</p>

<p>This error occurred on iPhone 5s/6s + a couple of different iPad's I tried (can't remember which). It also did not work on the HTC one. This error did not occur on any samsung/windows phones I tried. It also worked on desktops. (I have not tried to run it on a mac yet). </p>

How to mount a postgresql volume using Aws EBS in Kubernete : <ol>
<li>I've created the persistent volume (EBS 10G) and corresponding persistent volume claim first. But when I try to deploy the postgresql pods as below (yaml file) :</li>
</ol>
<p><a href="https://i.stack.imgur.com/1bM88.png" rel="noreferrer">test-postgresql.yaml</a></p>
<p>Receive the errors from pod:</p>
<p><strong>initdb: directory "/var/lib/postgresql/data" exists but is not empty
It contains a lost+found directory, perhaps due to it being a mount point.
Using a mount point directly as the data directory is not recommended.
Create a subdirectory under the mount point.</strong></p>
<p>Why the pod can't use this path? I've tried the same tests on minikube. I didn't meet any problem. </p>
<ol start="2">
<li>I tried to change volume mount directory path to "/var/lib/test/data", the pods can be running. I created a new table and some data on it, and then killed this pod. Kubernete created a new pod. But the new one didn't preserve the previous data and table. </li>
</ol>
<p>So what's the way to correctly mount a postgresql volume using Aws EBS in Kubernete, which allows the recreated pods can reuse initial data base stored in EBS?</p>

Is there something like a backtrace to indicate which path a variable has reached to its current value? : <p>I have a source like this</p>
<pre><code> //file1.cpp
int var_1=getDB(" Table_name","column_name");
...
//file2.cpp
int var2=func2(var_1);
...
//filen.cpp
int var_n=funcn(var_n_1);
</code></pre>
<p>In debugging, I first diagnose var_n error message type, but the goal is to modify the table, is there an easy way like backtrace to get to the source of the error, namely the table and field name?</p>

what's an easy way to cast one object to another (same props) : <p>What's an easy way to cast one object to another when they have the same properties? For example: </p>
<pre><code>public class Test1

public string FirstName{ get; set; }
public string LastName{ get; set; }
}
public class Test2
{
public string FirstName{ get; set; }
public string LastName{ get; set; }
}
</code></pre>
<p>So if I have a populated Test1 object and I want all of its values to be populated into Test2, then what's the easiest way to do that? I know I can set values 1-by-1 from Test1 to Test2 but I was wondering if you could recommend a quicker, easier way? Like test1.Map(test2) or something like that?</p>

Why putting a macros argument in parentheses leads to an error? : <p>I have one very interesting question about preprocessor directives in c++.</p>

if ((current b candidate) == false){\ // Marked Line
current = candidate;\

FUNCTION(minimum, <)

<p>My question is why changing the "Marked Line" with the following line of code won't even compile:</p>
<pre><code> ... if ((current (b) candidate) == false) ...

Where to get msbuild for Linux : <p>I want to build a .net core project on Windows and Linux.</p>
<p>For Windows I use MSBuild, simply downloaded the <code>Build Tools für Visual Studio 2017</code> from <a href="https://www.visualstudio.com/en/downloads/" rel="noreferrer">visualstudio.com</a>.</p>
<p>But where do I get MSBuild for Linux from? Based on the GitHub Project site, it should be available on some Linux distributions (<a href="https://github.com/Microsoft/msbuild/blob/master/README.md" rel="noreferrer">README.md</a>). I do not want to compile it myself (for some reasons).</p>
<p>I <strong>do not</strong> want to use xbuild, but pure MSBuild.</p>

Taking a 2 or more digit number as char in c : i have to write a program which i take a number as a character then find its binary so i used this code
[screenshotofmycode][1]
but it only works for numbers from 0 to 9.. it should work on 2 or more digit numbers.
I have to take the number as char because the user might enter the number in base 16 and i have to ask the number first then the basetype.... we are not allowed to use arrays.. Thanks in advanced..

Rendering a pandas dataframe as HTML with same styling as Jupyter Notebook : <p>I would like to render a pandas dataframe to HTML in the same way as the Jupyter Notebook does it, i.e. with all the bells and wistles like nice looking styling, column highlighting, and column sorting on click.</p>

<p><a href="https://pandas.pydata.org/pandas-docs/stable/generated/pandas.DataFrame.to_html.html" rel="noreferrer">pandas.to_html</a> outputs just a plain HTML table and requires manual styling etc. </p>
<p>Is the dataframe rendering code used by jupyter available as a standalone module that can be used in any web app? </p>
<p>Also, are the assets such as js/css files decoupled from jupyter so that they can be easily reused?</p>

Timeout in async/await : <p>I'm with Node.js and TypeScript and I'm using <code>async/await</code>.
This is my test case:</p>
<pre><code>async function doSomethingInSeries() {
const res1 = await callApi();
const res2 = await persistInDB(res1);
const res3 = await doHeavyComputation(res1);
return 'simle';
}
</code></pre>
<p>I'd like to set a timeout for the overall function. I.e. if <code>res1</code> takes 2 seconds, <code>res2</code> takes 0.5 seconds, <code>res3</code> takes 5 seconds I'd like to have a timeout that after 3 seconds let me throw an error.</p>
<p>With a normal <code>setTimeout</code> call is a problem because the scope is lost:</p>
<pre><code>async function doSomethingInSeries() {
const timerId = setTimeout(function() {
throw new Error('timeout');
});
const res1 = await callApi();
const res2 = await persistInDB(res1);
const res3 = await doHeavyComputation(res1);
clearTimeout(timerId);
return 'simle';
}
</code></pre>
<p>And I cannot catch it with normal <code>Promise.catch</code>:</p>
<pre><code>doSomethingInSeries().catch(function(err) {
// errors in res1, res2, res3 will be catched here
// but the setTimeout thing is not!!
});
</code></pre>
<p>Any ideas on how to resolve?</p>

when I ssh into RHEL7 AWS instance I get 'Permission denied (publickey,gssapi-keex,gssapi-with-mic)' : Ok so I know this question has been asked before. I tried everything that was posted in the closest related question and none of that worked. I was able to log in before but am not able to now.
- I have tried ssh-ing in with both root@ipadress and ec2-user@ipaddress neither have worked. When I use root it tells me to use ec2-user. I am ssh-ing from ubuntu 16.04
- I have the correct permissions on my pem file.
- Also I do not have a /etc/sshd_special_user file and not sure that adding one will do anything but it does seem to try to authenticate against my local user after failing the first time.
- When I ssh-keygen -f " ~/.ssh/known_hosts" -R xx.xx.xxx.xxx I get 'mkstemp: No such file or directory'. I am getting this even thought the file is there and I am able to open it in vim.
I am really confused as to what is going on here and am going to include the extra verbose log file with this question. I read through it and am not sure why it is doing what it is doing.

Sql programming logic- beginner level : I am a beginner in Sql programming. any pointers would help me.
Say we have table 1, table 2
say for one Server ID column in table 1 you have many application ID columns corresponding in table 2
Filter out many application ID columns for one particular server ID, then match it up with another markuptable (joining based on applicationtable. applnid= markup table.logical_name)
you need to output the markup id listed for all the application ids for that particular server

Try Catch for error message in google maps api : <p>I an using javascript and am getting an message that I have exceeded my daily request quota for this API.

Here is my code.</p>
<pre><code>(function (window, google, lat, lng) {

What exactly is a Set in COQ : <p>I'm still puzzled what the sort <strong>Set</strong> means in COQ. When do I use <strong>Set</strong> and when do I use <strong>Type</strong>?</p>
<p>In Hott a <strong>Set</strong> is defined as a type, where identity proofs are unique.
But I think in Coq it has a different interpretation. </p>

my code will not exicute the if/ elif part in this : so When I run this code(a portion of it) and I get to the word = input, it will run that and let me input my answer. But instead of doing the if / elif code, it will say exit code 0. I do not understand why this is happening so please help. I tried to remove code here and there but it changed nothing.
rand1 = random.randint(1, 2)
rand2 = random.randint(1, 4)
rand = random.randint(1, 1)
word = input("use a word that is 1-10 letters on a space, type a number 1 - 100 for the space: ")

a5 = word[4]
a6 = word[5]
a7 = word[6]
a8 = word[7]

count = count - 1

Cannot read property 'history' of undefined (useHistory hook of React Router 5) : <p>I am using the new useHistory hook of React Router, which came out a few weeks ago. My React-router version is 5.1.2. My React is at version 16.10.1. You can find my code at the bottom.</p>

}
return useContext(context).history; <---------------- ERROR IS ON THIS LINE !!!!!!!!!!!!!!!!!
}

<p>Since it is related to useContext and perhaps a conflict with context is at fault, I tried completely removing all calls to useContext, creating the provider, etc. However, that did nothing. Tried with React v16.8; same thing.
I have no idea what could be causing this, as every other feature of React router works fine.</p>
<p>***Note that the same thing happens when calling the other React router hooks, such as useLocation or useParams. </p>

Any help would be greatly appreciated, as I found nothing on the web related to this issue.</p>

How to write a modal with a nested array in spring? : I am writing a new class in spring boot where I need to write a modal class in which there will be a sub modal classes(I mean an array with a nested arrays), but when I try to run it I am getting the sub modal class names as attributes not the real attributes which I mentioned in sub modals.
**********ChangeBin Modal***********

}
public ChangebinPresent getChangebinpresent() {
return changebinpresent;
}
public void setChangebinpresent(ChangebinPresent changebinpresent)
{
this.changebinpresent = changebinpresent;
}
}
***********ChangebinPast -- Sub modal ******************
package com.demo.model;

Expected :
ChangeBin [

keycloak CORS filter spring boot : <p>I am using keycloak to secure my rest service. I am refering to the tutorial given <a href="http://slackspace.de/articles/authentication-with-spring-boot-angularjs-and-keycloak/" rel="noreferrer">here</a>. I created the rest and front end. Now when I add keycloak on the backend I get CORS error when my front end makes api call.</p>
<p>Application.java file in spring boot looks like</p>
<pre><code>@SpringBootApplication
public class Application
{
public static void main( String[] args )
{
SpringApplication.run(Application.class, args);
}

HttpMethod.PUT.toString(), HttpMethod.DELETE.toString(), HttpMethod.OPTIONS.toString())
.allowedOrigins("*");
}
};
}
}
</code></pre>
<p>The keycloak properties in the application.properties file look like</p>
<pre><code>keycloak.realm = demo
keycloak.auth-server-url = http://localhost:8080/auth
keycloak.ssl-required = external

<p>The CORS error that I get</p>
<pre><code>XMLHttpRequest cannot load http://localhost:8090/api/getSample. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:9000' is therefore not allowed access. The response had HTTP status code 401.

How to create nice-to-use type-checked aliases for primitive types in C++? : <p>I'm writing code where I'm creating multiple aliases for primitive types, e.g. <em>Address</em> and <em>Id</em> being <em>int</em>s.</p>
<p>I want to avoid using Addresses and Ids together, e.g. in arithmetic operations.</p>
<p>Thus I would like to have type-checking on these aliases, so that the following result can be obtained:</p>
<pre><code>typedef int A;
typedef int B;
A f(A a) { return a+a; };
int main()
{
A a = 5;
B b = 5;
f(a); // I would like this to work...
f(b); // and this not to compile.
}
</code></pre>
<p>Now this does not work, but I know I can use a wrapper struct/class with just one member:</p>
<pre><code>class A { public: int x; A(int xx) { x = xx; }};
class B { public: int x; B(int xx) { x = xx; }};
A f(A a) { return A(a.x+a.x); }; // this is ugly and I'd want to be able to use: return a+a
int main()
{
A a = 5;
B b = 5;
f(a); // This will work...
f(b); // This won't compile...
}
</code></pre>
<p><strong>My question is</strong> - what's the best way I can get code working like the 2nd snippet, but without having to explicitly getting <em>x</em> all the time and construct new objects (as noted in the line with the "this is ugly" comment)?</p>
<p>I guess I can overload all relevant operators for all my 'aliases' but that's a lot of work and I'm hoping there's a faster/nicer solution.</p>
<p>Thanks.</p>
<p>PS To make this a concrete SO question, not a discussion: I'm just asking for a different way of achieving the result I want, than overloading everything. Thank you.</p>

console.log('At %d', Date.now());

app.use(function(req, res, next) {
if(req.accepts('html') && res.status(404)) {
res.render('404.jade');

How to prevent RecyclerView item from blinking after notifyItemChanged(pos)? : <p>I currently have a recycler view whose data updates every 5 secs. To update the data on the list, I am using </p>
<pre><code>notifyItemChanged(position);
notifyItemRangeChanged(position, mList.size());
</code></pre>
<p>Each time I call notifyItemChanged(), the items on my recycler view update properly, however, it will blink because this causes onBindViewHolder to be called again. So it's as though it is a fresh load each time. How can I prevent this from happening, if possible?</p>
