How to know whether I need @ in Razor Pages? : I want to know the rule when I have to use `@` in Razor pages.
For example,
<div asp-validation-summary="ModelOnly">
<input asp-for="Movie.ID" />
<label asp-for="Movie.Title" ></label>
<span asp-validation-for="Movie.Title" >
we don't need `@` but
<a asp-page="Edit" asp-route-id="@Model.Movie.ID">Edit</a>
we do need `@`.
What is the rule? | 0debug |
I am not a programer, so I need your expertise on a macro with multiple "if" scenarios : Using Excel 2007, I am trying to do everything with one macro. Which is a combination of multiple if's.
If E147="ESM7" and C147="Bot", then the value shown in O150, if not, then the value shown in Q150.
But If E147="ESU7", then the value shown in O151, if not, then the value shown in Q151.
So, there are 4 if scenarios, beginning with the main cell is ESM7 or ESU7 ,then depending if the next cell value is either a Bot or SLD.
Thanks for your help. | 0debug |
Understanding "public" / "private" in typescript class : <p>In the below type script code , irrespective of whether name is "public" or
"private" , java script code that is generated is same.</p>
<p>So my question is, how to decide when the constructor parameter should be
public or private ? </p>
<pre><code>// typescript code
class Animal {
constructor( public name: string) {
}
}
// generated JS code
var Animal = (function () {
function Animal(name) {
this.name = name;

Typescript: Ignore imlicitly any type when importing js module : <p>In Typescript project I need to import some old js files that do module.exports inside of themselves.</p>
<p>As i import:</p>
<pre><code>import * as httpConnection from '...path...';
</code></pre>
<p>I got errors from compiler:</p>
<pre><code>Could not find a declaration file for module '...path...'. '...path...' implicitly has an 'any' type.
</code></pre>
<p>After that it works OK, but i need to avoid this error in console.</p>
<p>How can I make compiler understand that import has any type without creating declaration file?</p>
<p>Thanks for ideas in advance.</p>

Deploy path doesn't work for Git Deploy Method in middleman-deploy : <p>I am using <a href="https://github.com/middleman/middleman-blog" rel="noreferrer">middleman-blog</a> and <a href="https://github.com/middleman-contrib/middleman-deploy" rel="noreferrer">middleman-deploy</a>.</p>
<p>What I would like to do, is within the branch I am deploying to, I want the static files to be deployed to a subfolder within the repo (i.e. not the root folder).</p>
<p>I tried doing this in my <code>config.rb</code>:</p>
<pre><code>activate :deploy do |deploy|
deploy.build_before = true
deploy.deploy_method = :git
deploy.branch = 'gh-pages-2'
deploy.remote = 'github'
deploy.path = 'blog'
end
</code></pre>
<p>But that doesn't work, it still deploys to the root directory. In fact, it doesn't even create the <code>/blog</code> folder I am looking for.</p>
<p>When I visit the config settings locally, these are the settings I see under <code>:deploy</code>:</p>
<pre><code>:deploy
:branch = "gh-pages"
:build_before = true
:clean = false
:commit_message = nil
:deploy_method = :git
:flags = nil
:host = nil
:password = nil
:path = "blog"
:port = 22
:remote = "github"
:strategy = :force_push
:user = nil
</code></pre>
<p>This indicates to me that the path attribute is being set correctly.</p>
<p>I also tried doing <code>deploy.path = '/blog'</code> and that still doesn't work.</p>
<p>So how can I get this to deploy to <code>\blog\</code> subfolder within my repo rather than the root directory?</p>
<p>The versions of the different gems are as follows:</p>
<pre><code>middleman (4.1.10)
middleman-blog (4.0.1)
middleman-cli (4.1.10)
middleman-deploy (2.0.0.pre.alpha)
</code></pre>
<p><strong>Note:</strong> I am purposely using <code>gh-pages-2</code> because I don't want to overwrite my current <code>gh-pages</code> without being certain that it will deploy to the correct subfolder.</p>

Elasticsearch 2.1: Result window is too large (index.max_result_window) : <p>We retrieve information from Elasticsearch 2.1 and allow the user to page thru the results. When the user requests a high page number we get the following error message:</p>
<blockquote>
<p>Result window is too large, from + size must be less than or equal
to: [10000] but was [10020]. See the scroll api for a more efficient
way to request large data sets. This limit can be set by changing the
[index.max_result_window] index level parameter</p>
</blockquote>
<p>The elastic docu says that this is because of high memory consumption and to use the scrolling api:</p>
<blockquote>
<p>Values higher than can consume significant chunks of heap memory per
search and per shard executing the search. It’s safest to leave this
value as it is an use the scroll api for any deep scrolling <a href="https://www.elastic.co/guide/en/elasticsearch/reference/2.x/breaking_21_search_changes.html#_from_size_limits">https://www.elastic.co/guide/en/elasticsearch/reference/2.x/breaking_21_search_changes.html#_from_size_limits</a></p>
</blockquote>
<p>The thing is that I do not want to retrieve large data sets. I only want to retrieve a slice from the data set which is very high up in the result set. Also the scrolling docu says:</p>
<blockquote>
<p>Scrolling is not intended for real time user requests <a href="https://www.elastic.co/guide/en/elasticsearch/reference/2.2/search-request-scroll.html">https://www.elastic.co/guide/en/elasticsearch/reference/2.2/search-request-scroll.html</a></p>
</blockquote>
<p>This leaves me with some questions: </p>
<p>1) Would the memory consumption really be lower (any if so why) if I use the scrolling api to scroll up to result 10020 (and disregard everything below 10000) instead of doing a "normal" search request for result 10000-10020?</p>
<p>2) It does not seem that the scrolling API is an option for me but that I have to increase "index.max_result_window". Does anyone have any experience with this?</p>
<p>3) Are there any other options to solve my problem?</p>

php vs MySQLi, Which one is faster : <p>I want to execute a query to fetch data from 1000 rows in my database. I have found two methods to do that.</p>
<p>Method 1:</p>
<pre><code>SELECT * FROM user WHERE id=879
</code></pre>
<p>and second one which I used to protect myself from SQL Injection was:</p>
<p>Method 2:</p>
<pre><code><?php
$q="SELECT * FROM user";
$get_res=$dbconn->query($q);
while($set=$get_res->fetch_assoc()) {
if($set['id']==879)
{
//Some task here
}
}
</code></pre>
<p>So Which one is faster. I know about SQL prepared Statement.. But I just want to compare these two method.. And if there will be any security flaw in Method2 then Please explain that one also..</p>

Why is implicit conversion not ambiguous for non-primitive types? : <p>Given a simple class template with multiple implicit conversion functions (non-explicit constructor and conversion operator), as in the following example:</p>
<pre><code>template<class T>
class Foo
{
private:
T m_value;
public:
Foo();
Foo(const T& value):
m_value(value)
{
}
operator T() const {
return m_value;
}
bool operator==(const Foo<T>& other) const {
return m_value == other.m_value;
}
};
struct Bar
{
bool m;
bool operator==(const Bar& other) const {
return false;
}
};
int main(int argc, char *argv[])
{
Foo<bool> a (true);
bool b = false;
if(a == b) {
// This is ambiguous
}
Foo<int> c (1);
int d = 2;
if(c == d) {
// This is ambiguous
}
Foo<Bar> e (Bar{true});
Bar f = {false};
if(e == f) {
// This is not ambiguous. Why?
}
}
</code></pre>
<p>The comparison operators involving primitive types (<code>bool</code>, <code>int</code>) are ambiguous, as expected - the compiler does not know whether it should use the conversion operator to convert the left-hand template class instance to a primitive type or use the conversion constructor to convert the right-hand primitive type to the expected class template instance.</p>
<p>However, the last comparison, involving a simple <code>struct</code>, is not ambiguous. Why? Which conversion function will be used?</p>
<p>Tested with compiler msvc 15.9.7.</p>

Can anuone explain the below code How it works? : I have a custom class that has overridden hashcode() and equals() method
class Employee1{
private int id;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public Employee1(int id) {
super();
this.id = id;
}
@Override
public int hashCode() {
final int prime = 31;
int result = 1;
result = prime * result + id;
return result;
}
@Override
public boolean equals(Object obj) {
if (this == obj)
return true;
if (obj == null)
return false;
if (getClass() != obj.getClass())
return false;
Employee1 other = (Employee1) obj;
if (id != other.id)
return false;
return true;
}
}
and in main class I am using a Map having Object as Key
Map<Integer,Employee1> g = new HashMap<>();
Employee1 e = new Employee1(1);
Employee1 e1 = new Employee1(2);
g.put(1, e);
g.put(2, e1);
Employee1 e4 = g.get(1);
e4.setId(3);
for(Map.Entry<Integer,Employee1> e3:g.entrySet()) {
System.out.println(e3.getKey()+" "+e3.getValue().getId());
}
my question is how come the key of the map is changed even though I have overridden hashcode and equals methods,key should be same but I am able to get and set the id and its reflecting in the map
The o/p for above code is

Migration of Small Parse IDs to normal MongoDB's ObjectIDs : <p>I am using Parse Dashboard for User Management of my iOS Application.Also, I am using external APIs which are using MongoDB database.</p>
<p>The issue currently I am facing is the User created from Parse Dashboard is having small id instead of MongoDB's ObjectID, and other resources which are not over parse are generated by normal ObjectID.</p>
<p>eg. <strong>User Object:</strong></p>
<pre><code>{
_id:"qVnyrGynJE",
user_name:"Aditya Raval"
}
</code></pre>
<p><strong>Document Object:</strong></p>
<pre><code>{
_id:"507f191e810c19729de860ea",
doc_name:"Marksheet",
user:"qVnyrGynJE"
}
</code></pre>
<p><strong>Task Object:</strong></p>
<pre><code>{
_id:"507f191e810c19729de860ea",
task_name:"Marksheet",
user:"qVnyrGynJE"
}
</code></pre>
<p>I am also using Keystone.js as a Backend Admin Dashboard.So basically due to this mix kind of IDs relationships inside KeyStone.js is broken and Keystone.js gets crashed.</p>
<p>So I want to migrate all my existing small IDs to normal MongoDB ObjectIDs without breaking into relationships or any other walkthrough by fixing Keystone.js</p>

Cannot access $_GET variable from MVC : I have been following a course on Udemy.com and I have been stuck for a few days with no help from the instructor. My controller works as follows:
htaccess: `RewriteRule ^([a-zA-Z]*)/?([a-zA-Z]*)?/?([a-zA-Z0-9]*)?/?$ index.php?controller=$1&action=$2&id=$3 [NC,L]`
As you can see, the url is broken up into controller/action/id. This all works great, but the problem here is that when I try to pass a get variable into the URL it won't recognize it. The image below shows what I mean:

facebook graph api not work from 2.2 to 2.3 : <p>Because it's due date for graph api 2.2, I'm trying fix my graph api using v2.3
But I discover most api request response nothing when I use 2.3, but I can not found any update for this in the upgrade document. For example:</p>
<pre><code>https://graph.facebook.com/v2.3/{$user_id}?date_format=U&fields=albums.order(reverse_chronological).limit(100).offset(0){id,count,name,created_time}
</code></pre>
<p>will return nothing if I use 2.3.
And I can't get user's birthday when I call:</p>
<pre><code>https://graph.facebook.com/v2.3/{$user_id}
</code></pre>
<p>It's only return name and live location.
But in v2.2, it include birthday profile.</p>
<p>I use facebook SDK 3.2.2 because my php version is 5.3.
Is there any update that I don't know? Thanks.</p>

Set environment variable for build in Netlify : <p>I'm trying to set an environment variable for an API key that I don't want in my code. My source javascript looks something like this :</p>
<pre><code>.get(`http://api-url-and-parameters&api-key=${process.env.API_KEY}`)
</code></pre>
<p>I'm using webpack and the package dotenv-webpack <a href="https://www.npmjs.com/package/dotenv-webpack" rel="noreferrer">https://www.npmjs.com/package/dotenv-webpack</a> to set API_KEY in a gitignored .env file and it's all running fine on my local. I'd like to also be able to set that variable when deploying through Netlify, I've tried adding it through to GUI to the 'build environment variables', and also to set it directly in the build command, but without success.</p>
<p>Any idea what might be the issue ?</p>

PHP: Mark as link values inside a string (a textarea string) : <p>I'm developing a wikipedia-like Web application.
I want to show articles with the possibllity to link to other articles.</p>
<p>The way to do it that I can think of, is to mark manually values as a sign for link, like this: " Hello |world| " ("world" would be the link for an article). later, i'll have to find inside the textarea string all the words marked with | on start and | on it's end. bottom line, some string functions are needed. </p>
<p>How should I do that? can you, please, give me an example?</p>
<p>Thank you in advance.</p>

Clean Architecture: Use different model classes for different data sources? : <p>I am currently developing a news feed android app. I try to design my app according to the principles of clean architecture. </p>
<p>In the data layer I am using the repository pattern as a facade for the diferent data sources: remote data from an API (<a href="https://newsapi.org/" rel="noreferrer">https://newsapi.org/</a>) , local data from an DB (Realm or SQLite) as well as some in-memory cache.<br>
In my domain layer I have defined some immutable model classes (Article, NewsSource, etc.) which are being used by the domain layer as well as the presentation layer (no need for extra model classes in the presentation layer in my opinion). </p>
<p><strong>Does it make sense to use different model classes for the remote data source as well as for the local data source?</strong> </p>
<p>E.g. The remote data source uses Retrofit to make API calls and the models need to be annotated in order to be parsed by GSON.</p>
<pre><code>data class RemoteArticleModel(
@SerializedName("title") val title: String,
@SerializedName("urlToImage") val urlToImage: String,
@SerializedName("url") val url: String)
</code></pre>
<p>The models for the local data source also may have to fulfill some certain contract like models in a Realm DB need to extend RealmObject.</p>
<pre><code>open class Dog : RealmObject() {
var name: String? = null
@LinkingObjects("dog")
val owners: RealmResults<Person>? = null
}
</code></pre>
<p>Obviously, I don´t want my domain models to be 'polluted' by any data source specific contract (annotations, RealmObject inheritance, etc.). So I thought it would make sense to use different models for different data sources and the repository handles the mapping between them. </p>
<p><strong>E.g. We want to fetch all articles from the remote API, store them in the local DB and return them to the domain layer.</strong> </p>
<p><strong>Flow would be like:</strong>
Remote data source makes http request to news api and retrieves a list of <code>RemoteArticleModel</code>´s. The repository would map these models to a Domain specific article model (<code>Article</code>). Then these would be mapped to DB models (e.g. <code>RealmArticleModel</code>) and inserted into the DB. Finally the list of <code>Article</code>´s would be returned to the caller.</p>
<p><strong>Two questions arise:</strong>
The above example shows how <em>many allocations</em> there would be using this approach.
For every article that is going to be downloaded and inserted into the DB, three models would be created in that process. Would that be overkill?</p>
<p>Also, I know that the data layer should use different model classes than the domain layer (inner layer should no nothing about outer layer). But how would that make sense in the above example. I would already have two different model classes for the two different data sources. Adding a third one that´s being used as a 'mediator' model by the data-layer/repository to handle mapping to other models (remote, local, domain) would add even more allocations. </p>
<p><strong>So should the data layer know nothing about domain models and let the domain do the mapping from a data layer model to a domain layer model?</strong> </p>
<p><strong>Should there be a generic model used only by the repository/data-layer?</strong></p>
<p>Thank, I really appreciate any help from more experienced developers :)</p>

Building numpy with ATLAS/LAPACK support : <p>I am trying to compile <code>numpy</code> v1.12 in order to get support for ATLAS/LAPACK routines. </p>
<p><strong>The problem</strong></p>
<p>The settings I am using for compilation do not appear to work in bringing ATLAS/LAPACK libraries into <code>numpy</code>.</p>
<p><strong>The setup</strong></p>
<p>I do not have admin privileges on the host(s) I am working on (a computational cluster). </p>
<p>However, the nodes offer access to <code>gcc</code> 4.7.2 and 5.3.0, <code>glibc</code> 2.17 and 2.22, and ATLAS/LAPACK libraries and headers v3.10.2 via GNU modules.</p>
<p>For compatibility reasons, I am working with a virtual environment that contains Python 2.7.16. Likewise, I am installing an older version of <code>numpy</code> for the same reason. If things work, I may explore newer versions of <code>numpy</code> but at this time, that is what I am working with. </p>
<p>My source directory for <code>numpy</code> has a configuration file called <code>site.cfg</code>, which includes these directives:</p>
<pre><code>[ALL]
library_dirs = /usr/local/lib:/net/module/sw/glibc/2.22/lib64:/net/module/sw/atlas-lapack/3.10.2/lib
include_dirs = /usr/local/include:/net/module/sw/glibc/2.22/include:/net/module/sw/atlas-lapack/3.10.2/include
[atlas]
libraries = lapack,f77blas,cblas,atlas
library_dirs = /net/module/sw/atlas-lapack/3.10.2/lib
include_dirs = /net/module/sw/atlas-lapack/3.10.2/include
</code></pre>
<p>I am compiling <code>numpy</code> via the following command:</p>
<pre><code>$ CFLAGS="${CFLAGS} -std=c99 -fPIC" LDFLAGS="-L/home/areynolds/.conda/envs/genotyping_environment/lib -Wl,-rpath=/home/areynolds/.conda/envs/genotyping_environment/lib -Wl,--no-as-needed -Wl,--sysroot=/,-L/net/module/sw/glibc/2.22/lib64" python setup.py build --fcompiler=gnu95
</code></pre>
<p>I am using <code>--fcompiler=gnu95</code> as the ATLAS/LAPACK libraries were compiled with GNU Fortran. I am overriding <code>CFLAGS</code> and <code>LDFLAGS</code> variables in order for the GCC toolkit to be able to compile and link properly.</p>
<p><strong>The question</strong></p>
<p>After compilation, I test the <code>numpy</code> library to see what is installed via one method:</p>
<pre><code>$ python
...
>>> import numpy.distutils.system_info as sysinfo
>>> sysinfo.get_info('atlas')

<p>Despite the manual setup described in <code>site.cfg</code>, there are no mentions of ATLAS, nor is LAPACK apparently pointed to the correct module directory (<code>/net/module/sw/atlas-lapack/3.10.2</code>).</p>
<p>How do I correctly compile support for ATLAS/LAPACK into <code>numpy</code>, or truly test that I have a working ATLAS/LAPACK setup integrated into <code>numpy</code>, which gives me a consistent (and reliable) answer?</p>

Merging multiple TypeSafe Config files and resolving only after they are all merged : <p>I am writing test code to validate a RESTful service. I want to be able to point it at any of our different environments by simply changing an environment variable before executing the tests.</p>
<p>I want to be able to merge three different config files:</p>
<ul>
<li><code>conf/env/default.conf</code> - the default configuration values
for all environments</li>
<li><code>conf/env/<env>.conf</code> - the environment-specific
values </li>
<li><code>application.conf</code> - the user's overrides of any of the
above</li>
</ul>
<p>The idea is that I don't want everything in a single config file, and run the risk of a bad edit causing configuration items to get lost. So instead, keep them separate and give the user the ability to override them.</p>
<p>Here's where it gets tricky: <code>default.conf</code> will include ${references} to things that are meant to be overridden in <code><env>.conf</code>, and may be further overridden in <code>application.conf</code>. </p>
<p>I need to postpone resolving until all three are merged. How do I do that?</p>

How does `ggplotGrob` work? : <p><a href="http://docs.ggplot2.org/0.9.3/ggplotGrob.html">docs.ggplot2.org</a> currently offers very little documentation for the function <code>ggplotGrob</code>. The <a href="http://svitsrv25.epfl.ch/R-doc/library/ggplot2/html/ggplotGrob-1l.html">EPFL website</a> is a little bit more informative but it is still not very helpful.</p>
<p>Can you please provide a short tutorial on what one can do with the function <code>ggplotGrob</code>?</p>

How do I calculate Percentages of Variables in HTML : I pretty much just started learning to code so I know only the most basic info so I might not understand too many coding terms if their put out there.
I was trying to make a variable go up by a certain percent every time you click a button. I understand how I could do most of that, I just need to know how to multiply variables with percentages.
Could anyone explain to me how to multiply variables with percentages in html. | 0debug |
How do i reload data in my tableview : Ive seen some answers on Stack about this question but a lot of them are from 5 years ago and using an older version of swift. I would like to reload the data in the table every time the user hits save so that the appended event will now be added to the table. But no matter what i seem to do nothing is showing up!
class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
@IBOutlet weak var txtTitle: UITextField!
@IBOutlet weak var txtLocation: UITextField!
@IBOutlet weak var txtDate: UITextField!
@IBOutlet weak var txtTime: UITextField!
var eventsArray = [Event]()
override func viewDidLoad() {
super.viewDidLoad()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
//var events = Event(tits: "W", locs: "UVA-Wise")
@IBAction func btnSave() {
let event = Event(tits: txtTitle.text!, locs: txtLocation.text!)
eventsArray.append(event)
print(eventsArray)
//reload data
}
@IBOutlet weak var table: UITableView!
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return eventsArray.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell") as! CustomeCell
cell.title.text = eventsArray[indexPath.row].title
cell.location.text = eventsArray[indexPath.row].location

React Native init specific version : <p>I upgraded my latest project to React Native 0.19 and instantly the video no longer works. How can I create a new project with a specific version? I want to init a new project at version 0.18.1. I did some google searches but couldn't find anything about this.</p>
<pre><code>$ react-native init newproject --verbose

<p>I'm guessing I need to add the word @18.1 in there somewhere but can't get that to work.</p>

why does google appengine deployment take several minutes to update service : <p>I'm using nodejs flexible environment documented <a href="https://cloud.google.com/appengine/docs/flexible/nodejs/configuring-your-app-with-app-yaml" rel="noreferrer">here</a></p>
<p>Nothing fancy in the config</p>
<pre><code>runtime: nodejs
vm: true
service: SimpleExpressService
health_check:

min_num_instances: 1
max_num_instances: 4
cool_down_period_sec: 120
cpu_utilization:

</code></pre>
<p>Here is my deployment command</p>
<pre><code>gcloud app deploy -q --promote --version $VER
</code></pre>
<p>Whenever I deploy a new version, almost everything goes really fast. However, the step 'Updating service [SimpleExpressServer]' takes several minutes. </p>
<p>Is there anyway to optimize this step?</p>

How to use Schedulers.trampoline() inRxJava : <p>Since <code>Schedulers.trampoline()</code> makes the job work on the current thread,
I cannot find the difference between the case with <code>Schedulers.trampoline()</code> and the case without Schedulers settings.</p>
<p>Using <code>Schedulers.trampoline()</code>:</p>
<pre><code>Observable.from(1, 2, 3)
.observeOn(Schedulers.trampoline())
.subscribe(System.out::println)
</code></pre>
<p>Not Using Schedulers: </p>
<pre><code>Observable.from(1, 2, 3)
.subscribe(System.out::println)
</code></pre>
<p>I think that above codes act the same.
I really wonder why <code>Schedulers.trampoline()</code> exists in RxJava's API.</p>
<p>In what situation, should I use <code>Schedulers.trampoline()</code>?</p>

Should I keep gitconfig's "signingKey" private? : <p>I have recently set up GPG to sign my Git commits so now I have a <strong>signingKey</strong> field in my gitconfig. I'm not very familiar with details of GPG – is this signingKey a sensitive piece of information that I should keep private or does it fall into the public part of gpg? I have my gitconfig in a public repo where I keep my dotfiles and I was wondering if it's ok to have that field visible. </p>

Bootstrap 4: Align logo/brand to the right : Total noob here...
I'm trying to align the brand/logo on the right side of my navbar but when I manage to do that, the logo stays inside the collapse menu when I get to mobile view.
This is the correct position in desktop view:
