dynamic sized multi line TextBox field in a PDF : <p>I have created a document in open office with a multi line form field:</p>
<p><a href="https://i.stack.imgur.com/i1ZG2.png" rel="noreferrer"><img src="https://i.stack.imgur.com/i1ZG2.png" alt="enter image description here"></a></p>
<p>The issue I am having is when the dynamic content exceeds the initial size of the multi line text box:</p>
<p><a href="https://i.stack.imgur.com/h3JF8.png" rel="noreferrer"><img src="https://i.stack.imgur.com/h3JF8.png" alt="enter image description here"></a></p>
<p>Sure I can re-size the Text Box in the original template but the dynamic content may be from 1 to 50 lines and I want the text after the Text Box to be close to the last line of dynamic content.</p>
<p>Can someone suggest a way to solve this? </p>

Basic understanding of return function : <p>I'm having trouble of understanding the very basic concept of returning a value in functions (JS etc).</p>
<p>Why should I use</p>
<pre><code>function add(x,y){

return result;
}
add(5,3);
</code></pre>
<p>instead of</p>
<pre><code>var result=0;
function add(x,y){

PCA on word2vec embeddings : <p>I am trying to reproduce the results of this paper: <a href="https://arxiv.org/pdf/1607.06520.pdf" rel="noreferrer">https://arxiv.org/pdf/1607.06520.pdf</a></p>
<p>Specifically this part:</p>
<blockquote>
<p>To identify the gender subspace, we took the ten gender pair difference vectors and computed its principal components (PCs). As Figure 6 shows, there is a single direction that explains the majority of variance in these vectors. The first eigenvalue is significantly larger than the rest.</p>
</blockquote>
<p><a href="https://i.stack.imgur.com/EOJJK.png" rel="noreferrer"><img src="https://i.stack.imgur.com/EOJJK.png" alt="enter image description here"></a></p>
<p>I am using the same set of word vectors as the authors (Google News Corpus, 300 dimensions), which I load into word2vec. </p>
<p>The 'ten gender pair difference vectors' the authors refer to are computed from the following word pairs:</p>
<p><a href="https://i.stack.imgur.com/7b6Dj.png" rel="noreferrer"><img src="https://i.stack.imgur.com/7b6Dj.png" alt="enter image description here"></a></p>
<p>I've computed the differences between each normalized vector in the following way:</p>
<pre><code>model = gensim.models.KeyedVectors.load_word2vec_format('GoogleNews-vectors-
negative300.bin', binary = True)
model.init_sims()
pairs = [('she', 'he'),
('her', 'his'),
('woman', 'man'),
('Mary', 'John'),
('herself', 'himself'),
('daughter', 'son'),
('mother', 'father'),
('gal', 'guy'),
('girl', 'boy'),
('female', 'male')]
difference_matrix = np.array([model.word_vec(a[0], use_norm=True) - model.word_vec(a[1], use_norm=True) for a in pairs])
</code></pre>
<p>I then perform PCA on the resulting matrix, with 10 components, as per the paper:</p>
<pre><code>from sklearn.decomposition import PCA
pca = PCA(n_components=10)
pca.fit(difference_matrix)
</code></pre>
<p>However I get very different results when I look at <code>pca.explained_variance_ratio_</code> :</p>
<pre><code>array([ 2.83391436e-01, 2.48616155e-01, 1.90642492e-01,
9.98411858e-02, 5.61260498e-02, 5.29706681e-02,
2.75670634e-02, 2.21957722e-02, 1.86491774e-02,
1.99108478e-32])
</code></pre>
<p>or with a chart:</p>
<p><a href="https://i.stack.imgur.com/RuNEi.png" rel="noreferrer"><img src="https://i.stack.imgur.com/RuNEi.png" alt="enter image description here"></a></p>
<p>The first component accounts for less than 30% of the variance when it should be above 60%! </p>
<p>The results I get are similar to what I get when I try to do the PCA on randomly selected vectors, so I must be doing something wrong, but I can't figure out what.</p>
<p>Note: I've tried without normalizing the vectors, but I get the same results.</p>

Can I shorten the proccess of adding multiple variables in Python : basically I have a list and from.that list every variable uses one index for a value. Example:
val = [2, 4, 8, 6]
var1 = val[0]
var2 = val[1]
var3 = val[2]
var4 = val[3]
Can I put this in a loop somehow? Because I have cca 20 values so it is long to write 20 variables.
Thank you.
PS ofcourse, the values from added variables must be usable. | 0debug |

What are the differences between Decorator, Wrapper and Adapter patterns? : <p>I feel like I've been using these pattern families quite many times, however, for me it's hard to see the differences as their <em>definitions</em> are quite similar. Basicaly it seems like all of them is about <em>wrapping</em> another object or objects to extend or <em>wrap</em> their behavior with extra stuff. </p>
<p>For a quick example implementing a caching mechanism over a repository pattern seems to be this situation. Here is a quick sample <code>C#</code> code I would probably start with.</p>
<pre><code>public interface IRepository {
IEnumerable<T> GetItems<T>();
}
public class EntityFrameworkRepository : IRepository {
...
}
public class CachedRepository : IRepository {
private IRepository _repository;
private ICacheProvider _cache;
public CachedRepository(IRepository repository, ICacheProvider cache) {
this._repository = repository;
this._cache = cache;
}
public IEnumerable<T> GetItems<T>() {
...
}
}
</code></pre>
<p>Which one of these patterns apply to this situation for example? Could anyone clarify briefly the differences in theory and in practice?</p>

<p>And in my controller method I use</p>
<p><code>$this->middleware('Auth');</code></p>
<p>But this doesn't work at all.</p>
<p>And when I take my <code>'Auth' => \App\Http\Middleware\Auth::class,</code> and place it into <code>protected $middlewareGroups</code> like <code>\App\Http\Middleware\Auth::class,</code> it works. But for every single page. So when I am not logged it all time abort404.</p>
<p>What is wrong here?
I can't see, it looks fine to me.</p>
<p>But this middleware doesn't work for this method in which I have <code>$this->middleware('Auth');</code></p>
<p>I am not logged in but page appears as normal.</p>
<p>And there should be abort404 fired cuz I am not logged</p>
<p>What made I wrong?</p>

ASP.NET C# storing Session in DataBase : <p>i am new with ASP.NET and C#. I was trying to store details of a booking into the booking table including User ID using the session.
My booking table is as follow</p>
<pre><code>CREATE TABLE [dbo].[BookingTb] (
[Bid] INT IDENTITY (1, 1) NOT NULL,
[Rid] VARCHAR (5) NOT NULL,
[Price] MONEY NOT NULL,
[nights] INT NOT NULL,
[NoOfRooms] INT NOT NULL,
[Uid] VARCHAR(50) NOT NULL,
PRIMARY KEY CLUSTERED ([Bid] ASC));
</code></pre>
<p>and the user table is as follow</p>
<pre><code>CREATE TABLE [dbo].[UserTb] (
[Uid] VARCHAR (50) NOT NULL,
[Uname] VARCHAR (15) NOT NULL,
[Ubd] INT NOT NULL,
[Ugender] VARCHAR (10) NOT NULL,
[Uemail] VARCHAR (50) NOT NULL,
[password] VARCHAR (50) NOT NULL,
PRIMARY KEY CLUSTERED ([Uid] ASC));
</code></pre>
<p>i created the session in the login form as follow</p>
<pre><code>Session["Uid"] = TextBox1.Text.ToString();
</code></pre>
<p>Now i want to store different details in the Booking table including the session after the user log in so i used the following code:</p>
<pre><code>using System.Data;
using System.Data.SqlClient;
public partial class UserBooking : System.Web.UI.Page
{
DataClassesDataContext db = new DataClassesDataContext();
protected void Button1_Click(object sender, EventArgs e)
{
BookingTb b = new BookingTb();
Int32 rooms,nights, cap,price;
rooms = Convert.ToInt32(TextBox1.Text);
nights = Convert.ToInt32(TextBox2.Text);
cap = Convert.ToInt32(DropDownList2.SelectedItem.Value);
String type = DropDownList1.SelectedItem.Value;
String Rid;
String user =Convert.ToString(Session["Uid"]) ;
if (type == "Normal" && cap == 2)
{
Rid = "G01";
price = rooms * nights * 35;
b.Rid = Rid;
b.Price = price;
b.nights = nights;
b.Uid = user;
b.NoOfRooms = rooms;
db.BookingTbs.InsertOnSubmit(b);
db.SubmitChanges();
Label3.Text = "Thank you for Booking with us!</br> Total Payment= " + price;
}
</code></pre>
<p>the problem is i keep getting this error:</p>
<pre><code> Line 39:b.Uid = user;
Compiler Error Message: CS0029: Cannot implicitly convert type 'string' to 'int'
</code></pre>
<p>well, Uid is a varchar(50) not an int! how can i solve that? i tried many ways but non of them worked.</p>

Kubernetes: How to refer to one environment variable from another? : <p>I've a <code>Deployment</code> object where I expose the POD ID using the <a href="https://kubernetes.io/docs/tasks/inject-data-application/environment-variable-expose-pod-information/" rel="noreferrer">Downward API</a>. That works fine. However, I want to set up another env variable, log path, with reference to the POD ID. But, setting that variable value to <code>/var/log/mycompany/${POD_ID}/logs</code> isn't working, no logs are created in the container.
I can make the entrypoint script or the app aware of the POD ID, and build up the log path, but I'd rather not do that.</p>

No Individual User Accounts auth option in ASP.NET Core Web API template : <p>I am a bit confused as to why there is no Individual User Accounts authentication option in the latest ASP.NET Core Web API template.</p>
<p>Is it still possible to implement individual user accounts the way that the MVC template does or would it not make sense?</p>
<p>Let's say I am creating a stand-alone web API that is going to have all of my business logic and data layer that accesses the database which has the AspNet Identity tables. I plan on making calls to this API w/ an MVC app.</p>
<p>I know one way of doing this is to create an asp.net MVC app w/ individual user accounts auth and simply build the API right within the MVC app using a controllers/api folder. However, I don't want to do it this way because I want the API to be its own standalone project that can be hosted on a completely different server and accessed by multiple applications, not just an MVC app.</p>
<p>Can someone lead me in the right direction on how authentication typically works in this scenario since there is no template?</p>

Best way to find how many times an item in a list repeats in a row, in C#? : <p>Given a list, for example:
<code>List<int> _ = new List<int>() { 1, 1, 1, 3, 3, 4, 4, 1, 1, 8, 8, 8, 5, 6, 7, 7, 7, 7, 8, 8 };</code></p>
<p>What would be the best / fastest / most efficient way to find how many times an item repeats in a row, in C#?
For this list, the result I'd be looking for is something that looks like this:</p>
<p>1 * 3</p>
<p>3 * 2</p>
<p>4 * 2</p>
<p>1 * 2</p>
<p>8 * 3</p>
<p>5 * 1</p>
<p>6 * 1</p>
<p>7 * 4</p>
<p>8 * 2</p>
<p>Doesn't have to be in this odd multiplication format, I think it makes it a bit easier to understand.</p>
<p>I've been trying looping over the List and comparing each item to the next, but I inevitably get stuck, and don't really know what to do.</p>

Using variables in Gradle build script : <p>I am using Gradle in my project. I have a task for doing some extra configuration with my war. I need to build a string to use in my task like, lets say I have:</p>

<pre><code>springVersion=3.0.6.RELEASE
task extraStuff{
doStuff 'org.springframework:spring-web:${springVersion}@war'

How to get the content-length of the response from a request with fetch() : <p>I was getting an error when returning <code>response.json()</code> when I would do a request with an empty response body, so I'm trying to just return an empty object when there is an empty body. The approach I was going for is to check the <code>Content-Length</code> header of the response, however, somehow <code>response.headers.get('Content-Length')</code> somehow returns <code>null</code>. Here is my code:</p>
<pre><code>function fetchJSON(url, options, state = null) {
return fetch(url, Object.assign({}, options, {
// TODO: Add options here that should be there for every API call
// TODO: Add token if there is one
}))
.then(response => {
// Pass the JSON formatted body to the next handler
if (response.ok === true) {
if (response.headers.get('Content-Length') === 0) return {};
return response.json();
}
// If the response was not an 2xx code, throw the appropriate error
if (response.status === 401) throw new AuthorizationError("You are not authorized to perform this action");
// If it is an error code that we did not expect, throw an regular error and hope that it gets noticed by
// a developer
throw new Error("Unexpected response: " + JSON.stringify(response));
});
}
</code></pre>
<p>Could you maybe help me to find the <code>Content-Length</code> of the response or help me to find another approach?</p>

How to sum only one textbox value and show result in label in c# : <p>The question could be duplicate but my problem is totally different.</p>
<p>I have a one textbox and one label.</p>
<p>Example: label text is already exist with number like 450 Now I want to add number in textbox and the textbox value should be sum in 450 + 30 = 480 where 30 is textbox value.</p>
<p>what I have tried:</p>
<pre><code>lbl_TotalAmount.Text = lbl_TotalAmount.Text + txt_DeliveryCharges.Text;
</code></pre>
<p>The above Result is: <code>45030</code></p>
<p>Another Code I Have tried:</p>
<pre><code>double total = Convert.ToDouble(lbl_TotalAmount.Text);
double charges = Convert.ToDouble(txt_DeliveryCharges.Text);
double sum = total + charges;
lbl_TotalAmount.Text = String.Format(sum.ToString("0.00"));
</code></pre>
<p>The above code is going to sum every value that I put in the textbox and also when I remove one word the number is sum every time.</p>
<p>Please give me best solution I tried many solution to solve this but unable to do this.</p>
<p>Sorry for bad English.</p>

Ignoring files from checkin with certain pattern of change : <p>Since having started using <a href="https://www.nuget.org/packages/JetBrains.Annotations">JetBrains Annotations</a>, for my own benefit I've decorated all methods with <code>[CanBeNull]</code> or <code>[NotNull]</code></p>
<p>For example, the following line:</p>
<pre><code>public AccountController(IAccountService accountService)
</code></pre>
<p>Would be changed to:</p>
<pre><code> public AccountController([CanBeNull] IAccountService accountService)
</code></pre>
<p>Another example would be:</p>
<pre><code>public Account CreateAccountEntity(Account accountEnttity)
</code></pre>
<p>would be changed to:</p>
<pre><code> [CanBeNull]
public Account CreateAccountEntity([NotNull] Account accountEnttity)
</code></pre>
<p><strong>How can I bypass pending changes for annotations, specifically "[CanBeNull]", and have TFS completely ignore this change?</strong></p>

Why is Chrome coloring my cookie red when I set it from the inspector? : <p>If I open the inspector for a page, go to the Application tab, scroll down to Cookies in the left-hand list, expand it, and click my domain, I get a list of cookies set on the domain. I can add new entries to the list and edit existing ones, setting and updating cookies stored for that domain.</p>
<p>After upgrading to Chrome 73 if I try and set a cookie the browser colors the text red and does not set or save the cookie. How do I continue setting cookies in Chrome 73?</p>

I have to set a heading to the font-family "Cooper Black" but it never actually goes to it. : <p>I'm submitting the gist I have of it with the questions as well. It is specifically question 8 on the full blown assignment. <a href="https://gist.github.com/JStrong0037/67c1a09ccd1943be84f4" rel="nofollow">This</a> is the gist with all my code, but I used the line, font-family: 'Cooper Black', serif; which isn't working. </p>
<p>I feel pretty dumb that no matter what I've tried it never works for me. I've tried Chrome, Firefox, and Edge all three when opening this. I'm actually getting desperate to find the cause of the problem or what I'm doing wrong.</p>

Amazon S3 - different lifecycle rule for "subdirectory" than for parent "directory" : <p>Let's say I have the following data structure:</p>
<ul>
<li>/</li>
<li>/foo</li>
<li>/foo/bar</li>
<li>/foo/baz</li>
</ul>
<p>Is it possible to assign to it the following life-cycle rules:</p>
<ul>
<li>/ (1 month)</li>
<li>/foo (2 months)</li>
<li>/foo/bar (3 months)</li>
<li>/foo/baz (6 months)</li>
</ul>
<p>The official documentation is unfortunately self-contradictionary in this regard. It doesn't seem to work with AWS console, which makes me somewhat doubtful that SDKs/REST would be any different ;)</p>
<p>Failing at that my root problem is: I have 4 types of projects. The most rudimentary type has a few thousand projects, the other ones have a few dozen. Each type I am obligated to store for a different period of time. Each project contains hundreds of thousands of objects. It looks more or less as:</p>
<ul>
<li>type A, 90% of projects, x storage required</li>
<li>type B, 6% of projects, 2x storage required</li>
<li>type C, 3% of projects, 4x storage required</li>
<li>type D, 1% of projects, 8x storage required</li>
</ul>
<p>So far so simple. However. Projects may be upgraded or downgraded from one type to another. And as I said - I have a few thousand instances of the first type so I can't write specific rules for every one of them (remember 1000 rule limit per bucket). And since they may upgrade from one type to another I can't simply insert them in a their own folders as well (ex. only projects from a particular type) or bucket. Or so I think? Are there any other options open to me other than iterating over every object, every time I want to purge expired files - which I would seriously rather not do because of the sheer number of objects?</p>
<p>Maybe some kind of file "move/transfer" between buckets that doesn't modify the creation time metadata, and isn't costly for our server to process?</p>
<p>Would be much obliged :)</p>

adb -s 192.168.1.6:5555 ..... error: more than one device/emulator : <p>I am working with react native, and would like to switch adb to wifi for easier debugging.</p>

<p>Then I disconnect my usb cable and enter this command</p>
<pre><code>adb connect 192.168.1.6

<p>adb devices result in the following</p>
<pre><code>adb devices
List of devices attached
192.168.1.6:5555 device

<p>So it only shows one device connected.
However trying this command</p>
<pre><code>adb reverse tcp:8081 tcp:8081
</code></pre>
<p>gives me the following error even though only one device is shown with adb devices command as shown above</p>
<pre><code>error: more than one device/emulator

<p>So I tried this command but I also get the same error</p>
<pre><code>adb -s 192.168.1.6:5555 reverse tcp:8081 tcp:8081
error: more than one device/emulator

<p>Trying the following gives me the same error</p>
<pre><code>adb -s "192.168.1.6:5555" reverse tcp:8081 tcp:8081
adb -s "192.168.1.6" reverse tcp:8081 tcp:8081
adb -s 192.168.1.6 reverse tcp:8081 tcp:8081
</code></pre>
<p>even trying to use the device id which I copied when it was connected to usb resulted in the same error</p>
<pre><code>adb -s deviceid reverse tcp:8081 tcp:8081
</code></pre>
<p>Is there a way to make adb reverse work when adb is connected wireless?</p>

React Hook : Send data from child to parent component : <p>I'm looking for the easiest solution to pass data from a child component to his parent.</p>
<p>I've heard about using Context, pass trough properties or update props, but I don't know which one is the best solution.</p>
<p>I'm building an admin interface, with a PageComponent that contains a ChildComponent with a table where I can select multiple line. I want to send to my parent PageComponent the number of line I've selected in my ChildComponent.</p>
<p>Something like that :</p>
<p>PageComponent :</p>
<pre><code><div className="App">
<EnhancedTable />
<h2>count 0</h2>
(count should be updated from child)
</div>
</code></pre>
<p>ChildComponent : </p>
<pre><code> const EnhancedTable = () => {
const [count, setCount] = useState(0);
return (
<button onClick={() => setCount(count + 1)}>
Click me {count}
</button>
)
};
</code></pre>
<p>I'm sure it's a pretty simple thing to do, I don't want to use redux for that.</p>

How exactly c++ vtable works? (with example in the q.) : <p>lets take an c++ example:</p>
<pre><code>class A

public:
A() { cout << "hey" << endl; }
~A() { cout << "by" << endl; }
};
class B : public A
{
public:
B() {}
virtual ~B() { cout << "from b" << endl; }
};
int main()
{
A * a = new B[5];
delete[] a;
return 0;
}
</code></pre>
<p>the results of this code is an infinite loop of "by" , why is this?
B vtable supposed to be upcast to A that don't have vtable , so i would expected it to throw an exception when he try to reach the virtual constructor.</p>
<p>p.s.
where i can read on all kind of examples of wired constructor destructor behave? (with examples ) </p>

<p>And what to do with code reusability. For example i’ve created a new feature for website 1, how could i make this feature reachable for all my other sites without updating all websites separately.</p>
