What is the difference between subprocess.popen and subprocess.run | <p>I'm new to the <code>subprocess</code> module and the documentation leaves me wondering what the difference is between <code>subprocess.popen</code> and <code>subprocess.run</code>. Is there a difference in what the command does? Is one just newer? Which is better to use?</p> | 0 |
Defining a UDF that accepts an Array of objects in a Spark DataFrame? | <p>When working with Spark's DataFrames, User Defined Functions (UDFs) are required for mapping data in columns. UDFs require that argument types are explicitly specified. In my case, I need to manipulate a column that is made up of arrays of objects, and I do not know what type to use. Here's an example:</p>
<pre><code>import sqlContext.implicits._
// Start with some data. Each row (here, there's only one row)
// is a topic and a bunch of subjects
val data = sqlContext.read.json(sc.parallelize(Seq(
"""
|{
| "topic" : "pets",
| "subjects" : [
| {"type" : "cat", "score" : 10},
| {"type" : "dog", "score" : 1}
| ]
|}
""")))
</code></pre>
<p>It's relatively straightforward to use the built-in <code>org.apache.spark.sql.functions</code> to perform basic operations on the data in the columns</p>
<pre><code>import org.apache.spark.sql.functions.size
data.select($"topic", size($"subjects")).show
+-----+--------------+
|topic|size(subjects)|
+-----+--------------+
| pets| 2|
+-----+--------------+
</code></pre>
<p>and it's generally easy to write custom UDFs to perform arbitrary operations</p>
<pre><code>import org.apache.spark.sql.functions.udf
val enhance = udf { topic : String => topic.toUpperCase() }
data.select(enhance($"topic"), size($"subjects")).show
+----------+--------------+
|UDF(topic)|size(subjects)|
+----------+--------------+
| PETS| 2|
+----------+--------------+
</code></pre>
<p>But what if I want to use a UDF to manipulate the array of objects in the "subjects" column? What type do I use for the argument in the UDF? For example, if I want to reimplement the size function, instead of using the one provided by spark:</p>
<pre><code>val my_size = udf { subjects: Array[Something] => subjects.size }
data.select($"topic", my_size($"subjects")).show
</code></pre>
<p>Clearly <code>Array[Something]</code> does not work... what type should I use!? Should I ditch <code>Array[]</code> altogether? Poking around tells me <code>scala.collection.mutable.WrappedArray</code> may have something to do with it, but still there's another type I need to provide. </p> | 0 |
iOS. How to enable and disable rotation on each UIViewController? | <p>I have an UIViewController, I want to disable or enable rotation of the screen in different scenarios</p>

}
else {
rotateDevice = true
}

<p>How can I do that?</p> | 0 |
JPA Criteria multiselect with fetch | <p>I have following model:</p>
<pre><code>@Entity
@Table(name = "SAMPLE_TABLE")
@Audited
public class SampleModel implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "ID")
private Long id;
@Column(name = "NAME", nullable = false)
@NotEmpty
private String name;
@Column(name = "SHORT_NAME", nullable = true)
private String shortName;
@ManyToOne(fetch = FetchType.LAZY, optional = true)
@JoinColumn(name = "MENTOR_ID")
private User mentor;
//other fields here
//omitted getters/setters
}
</code></pre>
<p>Now I would like to query only columns: <code>id</code>, <code>name</code>, <code>shortName</code> and <strong><code>mentor</code></strong> which referes to <code>User</code> entity (not complete entity, because it has many other properties and I would like to have best performance).</p>
<p>When I write query:</p>
<pre><code>CriteriaBuilder builder = em.getCriteriaBuilder();
CriteriaQuery<SampleModel> query = builder.createQuery(SampleModel.class);
Root<SampleModel> root = query.from(SampleModel.class);
query.select(root).distinct(true);
root.fetch(SampleModel_.mentor, JoinType.LEFT);
query.multiselect(root.get(SampleModel_.id), root.get(SampleModel_.name), root.get(SampleModel_.shortName), root.get(SampleModel_.mentor));
query.orderBy(builder.asc(root.get(SampleModel_.name)));
TypedQuery<SampleModel> allQuery = em.createQuery(query);
return allQuery.getResultList();
</code></pre>
<p>I have following exception:</p>

How to reference and refresh a QueryTable in Excel 2016 in VBA | <p>I'm trying to refresh a query on a cell change, however I can't figure out how to reference the query.</p>

Howto upload multiple files with Spring Boot and test it with cURL | <p>I have implemented a Controller to upload multiple files:</p>
<pre><code>public class Image implements Serializable {
private MultipartFile file;
private Ingeger imageNumber;
...
}
@RequestMapping(value = "/upload", method = RequestMethod.POST)
public void handleFileUpload(@RequestBody Set<Image> images) {
...
}
</code></pre>
<p>I correctly checked the code using only <em>one</em> MultipartFile directly in the upload method using this command:</p>
<pre><code>curl http://localhost:8080/upload -X POST -F '[email protected];type=image/jpg' -H "Content-Type: multipart/form-data"
</code></pre>
<p>I need to extend it in three ways but don't know the correct syntax:</p>
<ol>
<li>POST a collection of JSON items</li>
<li>Add the field "imageNumber" for each item</li>
<li>Most tricky part: add a file nested to each item</li>

Template Editor AEM not working as expected | <p>We are using template editor in AEM 6.2 to create templates , and we have followed below steps to create a template-</p>
<p>1.Created page template as done in we-retail site.
2.Create empty page template using above page template.
3.Created template using empty page template.</p>
<p>Did following modifications on top of we retail page component as per our requirement-</p>
<ol>
<li><p>As we need to have header and footer as full width parsys i.e 1340 width and body as 940 width-</p>
<p>
.site-wrapper {
width:1340px;
}
.container {
width:940px;
}
</p></li>
</ol>
<p>So we did following modifications in /apps//components/structure/page/partials/body.html -</p>
<pre><code><div class="site-wrapper">
<div data-sly-resource="${ @ path='header', resourceType='/apps/<projectname>/components/structure/header'}"
data-sly-unwrap>
</div>
</div>
<div class="container"
data-sly-use.templatedContainer="com.day.cq.wcm.foundation.TemplatedContainer">
<sly data-sly-repeat="${templatedContainer.structureResources}"
data-sly-resource="${item.path @ resourceType=item.resourceType, decorationTagName='div'}" />
</div>
<div class="site-wrapper">
<div data-sly-resource="${ @ path='footer', resourceType='/apps/<projectname>/components/structure/footer'}" data-sly-unwrap></div>
</div>
</code></pre>
<p>Also we have few more components which will take full width on the page so i have added responsivegrid component under full width div.</p>
<p>But i am not able to edit the header and footer component in template as they are not under templateresource.</p>
<p>Also even if i add design dialog under header and footer i am not able to edit those components directly on the page in design mode even if they are unlocked.</p>
<p>Please let me know if i am doing anything wrong here or we cant customize body.html as in we-retail site.</p>
<p>I thought of using different parsys for full width and for body.
And i don't want to control using css as i have multiple components which are full width.</p>

Using Dynamic Pivot SQL in a View | <p>Gday All,</p>
<p>I've written some code to dynamically Pivot a table like <a href="https://stackoverflow.com/questions/20111418/sql-server-transpose-rows-to-columns">SQL Server : Transpose rows to columns</a></p>
<p>The code looks like this</p>
<pre><code>DECLARE @cols NVARCHAR(MAX), @sql NVARCHAR(MAX)
SET @cols = STUFF((SELECT DISTINCT ',' + QUOTENAME(FieldName)
FROM CORE_Items_Extra
WHERE Not(FieldName = '')
ORDER BY 1
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)'),1,1,'')
SET @sql = 'SELECT ItemID, ' + @cols + '
FROM
(
SELECT ItemID, FieldValue, FieldName
FROM CORE_Items_Extra
) AS SourceTable
PIVOT
(
MAX(FieldValue) FOR FieldName IN (' + @cols + ')
) AS PivotTable;'
EXECUTE(@sql)
</code></pre>
<p>Which works perfectly BUT I want to use it within a View, I've tried copying the code to a view and it works but wont save as it doesn't like the Declare statements in the view, I've got it working in a Stored Procedure but cant use Stored Procedures in a View, I think I need to have it as a Table-Valued Function but cant use the Execute statement within a TBF. I need to combine this data with another table in a view, and would like to keep it dynamic, so any ideas would be greatly appreciated :) We are using SQL 2008 R2</p> | 0 |
Installing 64 bit PyCharm on Windows 10 | <p>I have a Windows 10 Home 64-bit installed on a x64 laptop. I also have Python 3.4.3 Anaconda 2.3.0 (64-bit) (default, Mar 6 2015, 12:06:10) [MSC v.1600 64 bit (AMD64)] installed as well as 64-bit versions of Java, Firefox and Tortoise. </p>
<p>For some reason when I run the PyCharm installer it only offers me the option of a 32 bit installation (rather irritatingly it doesn't even allow me to download a 64 bit installer from the website). Of course 32-bit PyCharm can't interact with 64-bit Tortoise.</p>
<p>So, how can I force PyCharm to install the 64-bit version or do I have to downgrade Tortoise, Java, Firefox etc. to 32-bit? It really shouldn't be this difficult!</p> | 0 |

Selenium wait for element to be clickable python | <p>All, I'm needing a little assistance with Selenium waits. I can't seem to figure out how to wait for an element to be ready.</p>
<p>The element that I am needing to wait I can locate and click using my script via the code below...</p>
<pre><code>CreateJob = driver.find_element_by_xpath(".//*[@id='line']/div[1]/a")
</code></pre>
<p>or </p>
<pre><code>CreateJob = driver.find_element_by_partial_link_text("Create Activity")

<p>I'm needing to wait for this element to be on the page and clickable before I try to click on the element. </p>
<p>I can use the <code>sleep</code> command, but I have to wait for 5 seconds or more and it seems to be unreliable and errors out 1 out of 8 times or so. </p>

Django Rest Framework - Getting a model instance after serialization | <p>I've made a serializer, and I'm trying to create a <code>Booking</code> instance from the booking field in the serializer, after I've validated the POST data. However, because the <code>Booking</code> object has foreign keys, I'm getting the error: </p>
<blockquote>
<p>ValueError: Cannot assign "4": "Booking.activity" must be a "Activity" instance.</p>
</blockquote>
<p>Here's my view function:</p>
<pre><code>@api_view(['POST'])
def customer_charge(request):
serializer = ChargeCustomerRequestSerializer(data=request.data)
serializer.is_valid(raise_exception=True)
# trying to create an instance using the ReturnDict from the serializer
booking = Booking(**serializer.data['booking'])
booking.save()
</code></pre>
<p>Serializers.py where <code>BookingSerializer</code> is a ModelSerializer</p>
<pre><code>class ChargeCustomerRequestSerializer(serializers.Serializer):
booking = BookingSerializer()
customer = serializers.CharField(max_length=255)
class BookingSerializer(serializers.ModelSerializer):
class Meta:
model = Booking
fields = '__all__'
# I wanted to view the instances with the nested information available
# but this breaks the serializer validation if it's just given a foreign key
# depth = 1

<p>What is the correct way to create a model instance from a nested serializer?</p> | 0 |
How to make a CSS transform affect the flow of other elements | <p>I'm using CSS transitions with the <code>transform</code> property to shrinks elements when adding and removing them.</p>
<p>However one problem with this is that this property doesn't affect the flow of other elements, so it appears as though the element being deleted shrinks away, and then the rest of the elements jump suddenly.</p>
<p>If I were to animate the height property instead of using a transform this would be fine, however in actual usage I am using elements of variable height so I won't know what heights I can animate between.</p>
<hr>
<p><strong>Edit:</strong> people have suggested animating the <code>height</code> property (which won't work as stated above), or the <code>max-height</code> property. The <code>max-height</code> property will work to some extent, however you cannot align the timings perfectly as the transition will keep adjusting the <code>max-height</code> property past the actual height of the element until the end of the transition time.</p>
<p>Another problem with these approaches is that it does not use the smooth animations that you can achieve with the <code>transform</code> property. The object's transform will happen smoothly, however the movement of the following elements will stutter as the browser renders these transitions differently.</p>
<hr>
<p>Here's a JSFiddle with what I mean (try adding then removing elements, and see the jump when elements are removed):</p>

How to generate JWT Token with IdentityModel Extensions for .NET 5 | <p>I am using <a href="https://github.com/AzureAD/azure-activedirectory-identitymodel-extensions-for-dotnet" rel="noreferrer">IdentityModel Extensions for .NET</a> version 4 to generate JWT token with <em>symmetric key</em> and <em>SHA256</em> as below and it works perfectly:</p>

fetch - Missing boundary in multipart/form-data POST | <p>I want to send a <code>new FormData()</code> as the <code>body</code> of a <code>POST</code> request using the <a href="https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API" rel="nofollow noreferrer">fetch api</a></p>
<p>The operation looks something like this:</p>
<pre class="lang-js prettyprint-override"><code>var formData = new FormData()
formData.append('myfile', file, 'someFileName.csv')
fetch('https://api.myapp.com',
{
method: 'POST',
headers: {
"Content-Type": "multipart/form-data"
},
body: formData
}
)
</code></pre>
<p>The problem here is that the boundary, something like</p>
<pre class="lang-none prettyprint-override"><code>boundary=----WebKitFormBoundaryyEmKNDsBKjB7QEqu
</code></pre>
<p>never makes it into the <code>Content-Type:</code> header</p>
<p>It should look like this:</p>
<pre class="lang-none prettyprint-override"><code>Content-Type:multipart/form-data; boundary=----WebKitFormBoundaryyEmKNDsBKjB7QEqu
</code></pre>
<p>When you try the "same" operation with a <code>new XMLHttpRequest()</code>, like so:</p>
<pre class="lang-js prettyprint-override"><code>var request = new XMLHttpRequest()
request.open("POST", "https://api.mything.com")
request.withCredentials = true
request.send(formData)
</code></pre>
<p>the headers are correctly set</p>
<pre class="lang-none prettyprint-override"><code>Content-Type:multipart/form-data; boundary=----WebKitFormBoundaryyEmKNDsBKjB7QEqu
</code></pre>
<p>So my questions are:</p>
<ol>
<li>how do I make <code>fetch</code> behave exactly like <code>XMLHttpRequest</code> in this situation?</li>
<li>if this is not possible, why?</li>
</ol>
<p>Thanks everybody! This community is more or less the reason I have professional success.</p> | 0 |

How to apply different color in AppBar Title MUI? | <p>I am trying to use my custom color for <code>AppBar</code> header. The <code>AppBar</code> has title 'My AppBar'. I am using white as my primary theme color. It works well for the bar but the 'title' of the <code>AppBar</code> is also using same 'white' color'</p>
<p>Here is my code:</p>
<pre><code>import React from 'react';
import * as Colors from 'material-ui/styles/colors';
import MuiThemeProvider from 'material-ui/styles/MuiThemeProvider';
import getMuiTheme from 'material-ui/styles/getMuiTheme';
import AppBar from 'material-ui/AppBar';
import TextField from 'material-ui/TextField';
const muiTheme = getMuiTheme({
palette: {
textColor: Colors.darkBlack,
primary1Color: Colors.white,
primary2Color: Colors.indigo700,
accent1Color: Colors.redA200,
pickerHeaderColor: Colors.darkBlack,
},
appBar: {
height: 60,
},
});
class Main extends React.Component {
render() {
// MuiThemeProvider takes the theme as a property and passed it down the hierarchy
// using React's context feature.
return (
<MuiThemeProvider muiTheme={muiTheme}>
<AppBar title="My AppBar">

< TextField hintText = "username" / >
< TextField hintText = "password" / >
</div>
</AppBar>
</MuiThemeProvider>
);

<p>But, the palette styles override the <code>AppBar</code> 'title' color and no title is displaying. Should I include something or I have misplaced any ?</p>

Update Claims values in ASP.NET One Core | <p>I have a Web Application in MVC 6 (Asp.Net One Core), and I'm using Claims based authentication. In the Login method I set the Claims:</p>

new Claim("Email", content.Email),
new Claim("RoleId", content.RoleId.ToString()),
};
var ci = new ClaimsIdentity(claims, "password");
await HttpContext.Authentication.SignInAsync("Cookies", new ClaimsPrincipal(ci));
</code></pre>
<p>Now, if the user for example changes the email in the user profile, how can I change the e-mail value for the "Email" Claim? I have to SignOutAsync and SignInAsync again in order to update the cookie? The best solution is to save this into a classic session? There is a better solution? I'm totally wrong?</p>

open selected rows with pandas using "chunksize" and/or "iterator" | <p>I have a large csv file and I open it with pd.read_csv as it follows:</p>
<pre><code>df = pd.read_csv(path//fileName.csv, sep = ' ', header = None)
</code></pre>
<p>As the file is really large I would like to be able to open it in rows</p>
<pre><code>from 0 to 511
from 512 to 1023
from 1024 to 1535
...
from 512*n to 512*(n+1) - 1
</code></pre>
<p>Where n = 1, 2, 3 ...</p>
<p>If I add chunksize = 512 into the arguments of read_csv</p>
<pre><code>df = pd.read_csv(path//fileName.csv, sep = ' ', header = None, chunksize = 512)
</code></pre>
<p>and I type</p>
<pre><code>df.get_chunk(5)
</code></pre>
<p>Than I am able to open rows from 0 to 5 or I may be able to divide the file in parts of 512 rows using a for loop</p>
<pre><code>data = []
for chunks in df:
data = data + [chunk]
</code></pre>
<p>But this is quite useless as still the file has to be completelly opened and takes time. How can I read only rows from 512*n to 512*(n+1).</p>
<p>Looking around I often saw that "chunksize" is used together with "iterator" as it follows</p>
<pre><code> df = pd.read_csv(path//fileName.csv, sep = ' ', header = None, iterator = True, chunksize = 512)
</code></pre>
<p>But after many attempts I still don't understand which benefits provide me this boolean variable. Could you explain me it, please?</p> | 0 |

How to Slant/Skew only the bottom of the div | <p>I have been trying to add a Skew/Slant to the bottom of a div. I have had some success, as you can see below in my JSFiddle, I have managed to apply the skew but it's not completely how I wanted it.</p>
<p><a href="https://jsfiddle.net/hcow6kjr/" rel="nofollow noreferrer">https://jsfiddle.net/hcow6kjr/</a></p>
<p>Currently the Skew is applied to the top and bottom of the div the image resides in, this skew also seems to be applied to the image itself (if you take the skew off, you will see the image slightly rotate back to normal). I was wondering if it's possible to do the following adjustments, and how I may go about them...</p>
<p>1 - Apply the skew to <strong>only the bottom</strong> of the div the image resides in, not both as currently is.</p>
<p>2 - Not apply the skew to the image, so that the image sits flat horizontal (if that makes sense).</p>
<p><strong>HTML</strong></p>

In TypeScript an interface can extend a class, what for? | <p>in <a href="https://www.typescriptlang.org/docs/handbook/classes.html" rel="noreferrer">TypeScript Handbook</a>
in 'Using a class as an interface' section, there is an example of an interface which extends a class.</p>
<p><code>class Point { ... }
interface Point3d extends Point {...}</code></p>
<p>When can this be useful? Do you have any practical examples of this?</p> | 0 |
Python numpy float16 datatype operations, and float8? | <p>when performing math operations on float16 Numpy numbers, the result is also in float16 type number.
My question is how exactly the result is computed?
Say Im multiplying/adding two float16 numbers, does python generate the result in float32 and then truncate/round the result to float16? Or does the calculation performed in '16bit multiplexer/adder hardware' all the way?</p>
<p>another question - is there a float8 type? I couldnt find this one... if not, then why? Thank-you all!</p> | 0 |
Install libc++ on ubuntu | <p>I am wondering what is the right/easy way to install a binary libc++ on Ubuntu, in my case Trusty aka 14.04?</p>
<p>On the LLVM web site there are apt packages <a href="http://apt.llvm.org/" rel="noreferrer">http://apt.llvm.org/</a> and I have used these to install 3.9. However these packages don't seem to include libc++. I install the libc++-dev package but that seems to be a really old version. There are also binaries that can be downloaded <a href="http://llvm.org/releases/download.html#3.9.0" rel="noreferrer">http://llvm.org/releases/download.html#3.9.0</a>. These do seem to contain libc++ but I'm not sure if I can just copy bits of this into places like /usr/include/c++/v1, in fact I'm not really sure what bits I would need to copy. I am aware I can use libc++ from an alternate location as documented here <a href="http://libcxx.llvm.org/docs/UsingLibcxx.html" rel="noreferrer">http://libcxx.llvm.org/docs/UsingLibcxx.html</a> which I have tried. However I can't modify the build system of the large code base I work on to do this.</p>
<p>So is three any reason the apt packages don't include libc++ and any pointers to installing a binary would be gratefully recieved.</p> | 0 |

How can I use Angular 2 with NetBeans? | <p>I have tried every tutorial I could find to try to make a HTML/JS project with Angular 2 working on NetBeans, but none have worked. Maybe is my npm that is bugged (search, for example, doesn't work).</p>
<p>The <code>node_modules</code> folder that is created with <code>npm install</code> is grey on NetBeans and have some errors in some files (I don't know if this is normal). Any <code>.js</code> I try to import from <code>node_modules</code> folder gives the error <code>Failed to load resource: net::ERR_EMPTY_RESPONSE</code> / <code>Uncaught ReferenceError: System is not defined</code>.</p>
<p>Does anyone have any idea what could I be doing wrong? Or does anyone knows any tutorial that have the code to download so I can compare with what I'm doing and see what is the correct? Every tutorial I have found doesn't have any code to download, just some pieces of codes in the page for explanation.
Sory if this isn't a good question, but I have been trying to make this work since yesterday without success and I'm completely out of idea.</p> | 0 |
SSL Certificate not working - "no start line" Error - Apache2 Ubuntu 16.04.1 | <p>We're setting up a new subdomain at the office and using our wildcard SSL Cert we have. I've created my key, and my csr files. I've then sent to csr file off to get our cer file, which i now have. (I will posted commands I've run further down). I've then copied the files into the /etc/ssl/private and /etc/ssl/certs folders, and updated the apache conf file, after using a2ensite for our new domain. When trying to restart apache, the following error message is displayed:</p>

<p>When our domain was requested in the creation *.[domain] was entered, rather than star.[domain], as this is what is required by our provider.

asp.net core remove X-Powered-By cannot be done in middleware | <p>Why can I not remove X-Powered-By as part of my middleware that I am executing? I can remove it if I put in the web.config but not if I put it in the middleware. I am removing another header in the middleware "Server" : "Kestrel" which works and tells me my middleware is being executed. </p>
<p>I am using Visual Studio 2015, ASP.Net Core Web Application (.NET Framework), 1.0.0-rc2-final</p>
<p>My middleware</p>
<pre><code>public class ManageHttpHeadersMiddleware

{
_next = next;
}
public async Task Invoke(HttpContext context)
{
context.Response.OnStarting(() =>

app.UseMiddleware<ManageHttpHeadersMiddleware>();
app.UseJwtBearerAuthentication();
app.UseMvc();
app.UseSwaggerGen();
app.UseSwaggerUi();
}

<ol>
<li>Is it because of the order in which I am executing the middleware in
the Startup.Configure ? </li>
<li>Is it because of the event I am executing in
the middleware ? I have tried using OnCompleted but its obviously to late and does not then remove "Server" : "Kestrel" </li>
<li>Is it because its
added by Kestrel or IIS in Azure and the only way to remove is via
the web.config ?</li>
</ol>

Why Spring Boot Application class needs to have @Configuration annotation? | <p>I am learning about the Spring Framework but I can't understand what exactly the <code>@Configuration</code> annotation means and which classes should be annotated so. In the Spring Boot docs it is said that the Application class should be <code>@Configuration</code> class.</p>
<blockquote>
<p>Spring Boot favors Java-based configuration. Although it is possible
to call SpringApplication.run() with an XML source, we generally
recommend that your primary source is a @Configuration class.</p>
</blockquote>
<p>Trying to learn about <code>@Configuration</code> I find that annotating a class with the <code>@Configuration</code> indicates that the class can be used by the Spring IoC container as a source of bean definitions. </p>
<p>If that is so then how is this application class a source of bean definitions?</p>
<pre><code>@SpringBootApplication // same as @Configuration @EnableAutoConfiguration @ComponentScan
public class App
{
public static void main(String[] args) throws Exception {
SpringApplication.run(App.class, args);
}
}
</code></pre>
<p>I have pretty much understood most other basic concepts regarding Spring but I can't understand the purpose of <code>@Configuration</code> or which classes should be <code>@Configuration</code> classes? Can someone please help. Thanks !!</p> | 0 |

What are the rules of semicolon inference? | <blockquote>
<p>Kotlin provides “semicolon inference”: syntactically, subsentences (e.g., statements, declarations etc) are separated by the pseudo-token SEMI, which stands for “semicolon or newline”. In most cases, there’s no need for semicolons in Kotlin code.</p>
</blockquote>
<p>This is what the <a href="https://kotlinlang.org/docs/reference/grammar.html" rel="noreferrer">grammar</a> page says. This seems to imply that there is a need to specify semicolons in some cases, but it doesn't specify them, and the grammar tree below doesn't exactly make this obvious. Also I have suspicions that there are some cases where this feature may not work correctly and cause problems.</p>
<p>So the question is when should one insert a semicolon and what are the corner cases one needs to be aware of to avoid writing erroneous code?</p> | 0 |

VBA running Access Query from Excel | <p>I am trying to run a VBA script that will Run and Export an Access query. I'm able to get to the step in code where I run the query, however, I need to connect to DB2 to run this query in Access and I don't know how to implement into my code to enter the username and password.</p>
<pre><code>Sub RunQuery()
Dim A As Object
Application.DisplayAlerts = False
Set A = CreateObject("Access.Application")
A.Visible = False
A.OpenCurrentDatabase ("J:\user\filename.mdb")
A.DoCmd.OpenQuery "QueryName"
A.DoCmd.ConnectString
Application.DisplayAlerts = True
End Sub
</code></pre>
<p>The code just stalls at the line:</p>
<pre><code>A.DoCmd.OpenQuery "QueryName"
</code></pre>
<p>And If I open my Database from here with my query it is just waiting for my username and password. I'll try and attach a picture of the prompt.</p>
<p>Any help would be greatly appreciated!!</p>

How to check if an array index exists using Ruby and/or Rails | <p>Is there a Ruby (preferably) or Rails way to check if the second index of an array exists?</p>
<p>In my Rails (4.2.6) app I have the following code in my view that shows the first two thumbnails for an array of photos:</p>
<pre><code><% if array.photos.any? %>
<%= image_tag array.photos.first.image.url(:thumb) %>
<%= image_tag array.photos[1].image.url(:thumb) %>
<% end %>
</code></pre>
<p>However if there is no second item in the array, then there is an error</p>
<p>I've tried the following <code>if</code> statements to make the rendering of the second thumbnail conditional, but they don't work:</p>
<pre><code><% if array.photos.include?(1) %>
<% if array.photos.second? %>
<% if array.photos[1]? %>
<% if array.photos[1].any? %>
</code></pre>
<p>I figured that another way to get what I want would be to simply check the length of the array</p>
<p>Still I was wondering if Ruby (or Rails) had a method or way to check if a specific index in an array exists or not. Thanks in advance</p>
<p>EDIT: To clarify I just want to show the first two thumbnails in the array, if any</p> | 0 |

MongoDb: add element to array if not exists | <p>I'm using node.js and Mongo.db (I'm newly on Mongo). I have a document like this:</p>
<pre><code>Tag : {
name: string,
videoIDs: array
}
</code></pre>
<p>The idea is, the server receives a JSON like </p>
<pre><code>JSON: {
name: "sport",
videoId: "34f54e34c"
}
</code></pre>
<p>with this JSON, it has to find the tag with the same name and check if in the array it has the <code>videoId</code>, if not, insert it to the array.</p>
<p>How can I check the array and append data?</p> | 0 |
How to ignore NULL byte when reading a csv file | <p>I'm reading a csv file generated from an equipment and I got this error message:</p>

Explicitly disable caching for REST services | <p>I am to apply <code>Cache-Control: must-revalidate,no-cache,no-store</code> to all responses from out backend REST services. I have two questions about it:</p>
<ul>
<li>Is it common to do so? For some reason I was under the impression that it's not necessary, but I have no source to back this claim (yet).</li>
<li>Is the value I mentioned above really sufficient, or should I set more?</li>
</ul>
<p>Edit: found this: <a href="https://devcenter.heroku.com/articles/increasing-application-performance-with-http-cache-headers#cache-prevention" rel="noreferrer">https://devcenter.heroku.com/articles/increasing-application-performance-with-http-cache-headers#cache-prevention</a>. Is says browsers may choose to cache when nothing is explicitly configured, so it means yes, it should be configured if I want to make sure cache is disabled.</p> | 0 |
Using AJAX call in MVC5 | <p>I have tried to use AJAX call in an MVC5 project as many similar examples on the web, but every time there is an error i.e. antiforgerytoken, 500, etc. I am looking at a proper AJAX call method with Controller Action method that has all the necessary properties and sending model data from View to Controller Action. Here are the methods I used:</p>
<p><strong>View:</strong></p>
<pre><code>@using (Html.BeginForm("Insert", "Account", FormMethod.Post, new { id = "frmRegister" }))
{
@Html.AntiForgeryToken()
//code omitted for brevity
}
<script>
AddAntiForgeryToken = function (data) {
data.__RequestVerificationToken = $('#__AjaxAntiForgeryForm input[name=__RequestVerificationToken]').val();
return data;
};
$('form').submit(function (event) {
event.preventDefault();
//var formdata = JSON.stringify(@Model); //NOT WORKING???
var formdata = new FormData($('#frmRegister').get(0));
//var token = $('[name=__RequestVerificationToken]').val(); //I also tried to use this instead of "AddAntiForgeryToken" method but I encounter another error
$.ajax({
type: "POST",
url: "/Account/Insert",
data: AddAntiForgeryToken({ model: formdata }),
//data: { data: formdata, __RequestVerificationToken: token },
//contentType: "application/json",
processData: false,
contentType: false,
datatype: "json",
success: function (data) {
$('#result').html(data);
}
});
});
</script>
</code></pre>
<p>Controller: Code cannot hit to this Action method due to antiforgerytoken or similar problem. </p>
<pre><code>[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public JsonResult Insert(RegisterViewModel model)
{
try
{
//...
//code omitted for brevity
}
}
</code></pre>
<p>I just need a proper AJAX and Action methods that can be used for CRUD operations in MVC5. Any help would be appreciated.</p>
<p><strong>UPDATE:</strong> Here is some points about which I need to be clarified:</p>
<p>1) We did not use "__RequestVerificationToken" and I am not sure if we send it to the Controller properly (it seems to be as cookie in the Request Headers of Firebug, but I am not sure if it is OK or not). Any idea? </p>
<p>2) Should I use var formdata = new FormData($('#frmRegister').get(0)); when I upload files? </p>
<p>3) Why do I have to avoid using processData and contentType in this scenario? </p>
<p>4) Is the Controller method and error part of the AJAX method are OK? Or is there any missing or extra part there? </p> | 0 |

Get AM/PM from HTML time input | <p>First, I know that <code><input type="time"></code> is not supported by IE10 or earlier, and Firefox, but this is only for testing purposes and I will make appropriate, cross-browser changes at another time.</p>
<p>For the time being, I have a HTML time input field. I am trying to extract the values from it including the hour, minutes and AM/PM. I can display the hour and minutes, but an AM/PM indication is not including.</p>
<p>I have an input as follows:</p>
<p><code><input type="time" name="end-time" id="end-time"></code></p>
<p>I print out via <code>alert()</code> the input value as follows:</p>
<p><code>alert(document.getElementById('end-time').value);</code></p>
<p>Upon input I receive an alert such as:</p>

How to get the request url in retrofit 2.0 with rxjava? | <p>I'm trying to upgrade to Retrofit 2.0 and add RxJava in my android project. I'm making an api call and want to retrieve the url and it with the response data in sqlite as a cache</p>
<pre><code>Observable<MyResponseObject> apiCall(@Body body);
</code></pre>
<p>And in the RxJava call:</p>
<pre><code>myRetrofitObject.apiCall(body).subscribe(new Subscriber<MyResponseObject>() {
@Override
public void onCompleted() {
}
@Override
public void onError(Throwable e) {
}
@Override
public void onNext(MyResponseObject myResponseObject) {
}
});
</code></pre>
<p>In Retrofit 1.9, we could get the url in the success callback:</p>
<pre><code> @Override
public void success(MyResponseObject object, Response response) {
String url=response.getUrl();
//save object data and url to sqlite
}
</code></pre>
<p>How do you do this with Retrofit 2.0 using RxJava?</p> | 0 |
Autocomplete with ajax call(Json) in laravel, no response | <p><strong>I have the view:</strong></p>
<pre><code><link rel="stylesheet" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.10.1/themes/base/minified/jquery-ui.min.css" type="text/css" />
<script>
$(function()
{
$( "#q" ).autocomplete({
source : "{{ url('search/autocomplete') }}",
minLength: 3,
select: function(event, ui) {
$('#q').val(ui.item.value);
}
});
});
</script>
<input id="q" placeholder="Search users" name="q" type="text" value="">
</code></pre>
<p><strong>Controller:</strong></p>
<pre><code><?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\NewTheme;
use App\Http\Requests;
use DB;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Input;
use Auth;
use Response;
class SearchController extends Controller
{
public function autocomplete(){
$term = Input::get('term');
$results = array();
// this will query the users table matching the TagName
$queries = DB::table('New_Themes')
->where('TagName', 'like', '%'.$term.'%')
->take(5)->get();
foreach ($queries as $query)
{
$results[] = ['value' => $query->TagName];
}
return Response::json($results);
}
}
</code></pre>
<p><strong>And my route:</strong></p>
<pre><code>Route::get('search/autocomplete', 'SearchController@autocomplete');
</code></pre>
<p>My problem is that when I type more then 3 letters in input tag I don't get anything, which seems that input with q id isn't filled with the values. If I do add the form/action/method thing with submit button the controller works fine, so the problem is in this ajax call which doesn't work properly.</p>
<p>Any thoughts why this isn't working properly(maybe it the ajax call doesn't get properly to route or something like this)?</p>

Finding an object in array and taking values from that to present in a select list | <p>I have a string value (e.g. "Table 1") that I need to use to find a specific object in an array that looks like so:</p>
<pre><code>[
{
lookups: [],
rows: [{data: {a: 1, b: 2}}, {data: {a: 3, b: 4}}],
title: "Table 1",
columns: [{name: "a"}, {name: "b"}]
},
{
lookups: [],
rows: [{data: {c: 5, d: 6}}, {data: {c: 7, d: 8}}],
title: "Table 2",
columns: [{name: "c"}, {name: "d"}]
}
]
</code></pre>
<p>Once I have found that object I then need to take the values from the columns key and display them in a select list.</p>
<p>I know how to do the second part, but it is getting access to the object in the first place that I am having trouble with. I am trying to do this within a React component render.</p>
<p>Any help with this would be greatly appreciated.</p>
<p>Thanks for your time.</p> | 0 |

Regular expression with if condition | <p>I am new to regular expression. I am trying to construct a regular expression that
first three characters must be alphabets and then the rest of the string could be any character. If the part of the string after first three characters contains & then this part should start and end with <code>"</code>.</p>
<p>I was able to construct <code>^[a-z]{3}</code>, but stuck at conditional statement.</p>
<p>For example <code>abcENT</code> and <code>abc"E&T"</code> are valid strings but not <code>abcE&T</code>.</p>
<p>Can this be done in a single expression?</p> | 0 |
