How to create and use a lookup table : <p>I have a character vector of misspelled words:</p>
<pre><code>wordswrong <- c("veh", "crrts", "ornges")
wordscorrect <- c("vehicle", "carrots", "oranges")
</code></pre>
<p>Here's a dataframe:</p>
<pre><code>words <- data.frame(terms = c("crrts oranges",
+ "car is a veh",
+ "orngs bannas peas"))
</code></pre>
<p>How can I go through each word in words$terms and update based on my two vectors?</p>

<p>The above code will work properly if "numberOfTicks" is just a number, (as the plunker original example shows) but once I change it to an array and push data, it won't update.</p>
<p>I can't seem to understand why is that.</p>
<p>The following behaviour is similar to an issue I have when trying to update a graph in angular2 with new data points when using setInterval / setTimeout.</p>
<p>Thanks for the help.</p>

C++ CLI Wrapper for native functions : I'm trying to create a C++ CLI .Net wrapper for some native DLLs.
There is seven of these DLLs and more in the future so i need to load the dynamically. They all have the same set of functions.
LoadLibrary and GetProcAddress worked great in a native application to load these functions.
Whenever i load a DLL, and call Initialize i get AccessViolationException.
Not really sure why.
It seems to Load the DLL fine and also the function "TSRInit"
If I pass in a path to the DLL i know is incorrect it tells me loading it failed. But doesnt say failed if I pass the correct path.
Likewise, Loading "TRInit" seems to work.
If i pass in a function name that doesnt exist it also tells me.
Im testing with a C# Console app with platform x86 selected.

namespace Imagery

Notepad-like GUI text editor for Linux/Ubuntu (SSH into an Ubuntu Server 14.04 LTS AWS instance) : <p>I am not so familiar with Linux/Ubuntu bash command line. I am currently ssh'ing (using ConEmu) into an AWS instance (Ubuntu Server 14.04 LTS) in order to setup a Jupyter notebook server. However, in a part of the documentation in requires editing a file using the vim editor. Vim seems a but confusing right now to learn and I just need to edit a couple lines.</p>
<p>Is there something similar in linux to the windows command line:</p>
<pre><code>notepad file_name.txt

<p>that opens a text file in a GUI for editing/saving. Is there a similar command line argument in Linux? Or something I can install which will give me this ability?</p>

Use rle to group by runs when using dplyr : <p>In R, I want to summarize my data after grouping it based on the runs of a variable <code>x</code> (aka each group of the data corresponds to a subset of the data where consecutive <code>x</code> values are the same). For instance, consider the following data frame, where I want to compute the average <code>y</code> value within each run of <code>x</code>:</p>
<pre><code>(dat <- data.frame(x=c(1, 1, 1, 2, 2, 1, 2), y=1:7))
# x y
# 1 1 1
# 2 1 2
# 3 1 3
# 4 2 4
# 5 2 5
# 6 1 6
# 7 2 7
</code></pre>
<p>In this example, the <code>x</code> variable has runs of length 3, then 2, then 1, and finally 1, taking values 1, 2, 1, and 2 in those four runs. The corresponding means of <code>y</code> in those groups are 2, 4.5, 6, and 7.</p>
<p>It is easy to carry out this grouped operation in base R using <code>tapply</code>, passing <code>dat$y</code> as the data, using <code>rle</code> to compute the run number from <code>dat$x</code>, and passing the desired summary function:</p>
<pre><code>tapply(dat$y, with(rle(dat$x), rep(seq_along(lengths), lengths)), mean)
# 1 2 3 4
# 2.0 4.5 6.0 7.0
</code></pre>
<p>I figured I would be able to pretty directly carry over this logic to dplyr, but my attempts so far have all ended in errors:</p>
<pre><code>library(dplyr)
# First attempt
dat %>%
group_by(with(rle(x), rep(seq_along(lengths), lengths))) %>%
summarize(mean(y))
# Error: cannot coerce type 'closure' to vector of type 'integer'
# Attempt 2 -- maybe "with" is the problem?
dat %>%
group_by(rep(seq_along(rle(x)$lengths), rle(x)$lengths)) %>%
summarize(mean(y))
# Error: invalid subscript type 'closure'
</code></pre>
<p>For completeness, I could reimplement the <code>rle</code> run id myself using <code>cumsum</code>, <code>head</code>, and <code>tail</code> to get around this, but it makes the grouping code tougher to read and involves a bit of reinventing the wheel:</p>
<pre><code>dat %>%
group_by(run=cumsum(c(1, head(x, -1) != tail(x, -1)))) %>%
summarize(mean(y))
# run mean(y)
# (dbl) (dbl)
# 1 1 2.0
# 2 2 4.5
# 3 3 6.0
# 4 4 7.0
</code></pre>
<p>What is causing my <code>rle</code>-based grouping code to fail in <code>dplyr</code>, and is there any solution that enables me to keep using <code>rle</code> when grouping by run id?</p>

Selenium Chrome window running in second monitor screen stealing focus : <p>I use WebDriver with Chrome Driver 2.35 with Selenium. </p>
<p>I have a dual monitor setup in which I run my test cases. I do run my cases headlessly most of the times but sometimes, when I want to debug, I run it with the browser. </p>
<p>The window opens, I drag it to my second monitor and continue working with other stuff in my primary monitor. But whenever there is an action in the secondary Chrome Selenium screen, the focus shifts to that window and I lose control. </p>
<p>This is really annoying, has anyone else faced this issue? Any solutions?</p>

I run command `composer create-project laravel/laravel api 5.5.*` in folder one of my site etc. `name.com`. I want to access it through URL: `https://name.com/api/public` - but I'm getting error on fresh new installation said '**Sorry, the page you are looking for could not be found.**'.
Also I tried to run it with `php artisan serve --host=0.0.0.0` but it show same page.

What is the Elasticsearch-py equivalent to alias actions? : <p>I am trying to implement <a href="https://www.elastic.co/guide/en/elasticsearch/guide/current/multiple-indices.html#multiple-indices" rel="noreferrer">multiples indices</a> approach using <a href="https://elasticsearch-dsl.readthedocs.io/en/latest/" rel="noreferrer">elasticsearch-dsl</a>. There are basically two steps:</p>
<p><strong>1. Create aliases:</strong></p>
<pre><code>PUT /tweets_1/_alias/tweets_search
PUT /tweets_1/_alias/tweets_index
</code></pre>
<p><strong>2. Change alias when necessary:</strong></p>
<pre><code>POST /_aliases
{
"actions": [
{ "add": { "index": "tweets_2", "alias": "tweets_search" }},
{ "remove": { "index": "tweets_1", "alias": "tweets_index" }},
{ "add": { "index": "tweets_2", "alias": "tweets_index" }}
]
}
</code></pre>
<p>I could only implement the step 1 using <a href="http://elasticsearch-py.readthedocs.io/en/master/index.html" rel="noreferrer">elasticsearch-py</a> (not the dsl):</p>
<pre><code>from elasticsearch.client import IndicesClient
IndicesClient(client).("tweets_1", "tweets_search")
IndicesClient(client).("tweets_1", "tweets_index")
</code></pre>
<p>I have no clue how to do that for step 2. So, what would be the equivalent in elasticsearch-dsl (or at least in elasticsearch-py)?</p>

How to call a class from a winform? : <p>Sorry I use this title on purpose. I m quite new on c# and i don't manage to call my class on the usual way.</p>
<p>I have a winform and I want to insert a class (copy and paste from an API), and call it from my winform. </p>
<p>This class is a program which open the console, ask me parameters and then lunch an EMG acquisition.</p>
<p>the class is like that:</p>
<pre><code> class Program1
{
static void Main(string[] args)
{
// some code here, with a lot of "Console.Writeline"
}
}
</code></pre>
<p>It works fine.</p>
<p>I change it to:</p>
<pre><code> public class Program1
{
public void method1(string[] args)
{
//some code here, , with a lot of "Console.Writeline"
}
}
</code></pre>
<p>And i tried to call it on my form </p>
<pre><code> private void button1_Click(object sender, EventArgs e)
{
Program1 program = new Program1();
program.method1();
}
</code></pre>
<p>it says "No overload for method 'method1' takes 0 arguments" .
The thing i don"t understand is when i run the program of the API alone it doesn't ask me anything it just runs. </p>
<p>I'm pretty sure the error is from the <code>Console.WriteLine</code> and <code>Console.Readline</code> but i don't know how to resolve my problem.
I want a button on my winform which run my class, open the console and ask me on the console which paramaters i want.</p>

How to specify which domain using ngrok : <p>I use mamp and I have virtual hosts all on port 8888. For example:</p>
<ul>
<li>site1.dev:8888</li>
<li>site2.dev:8888</li>
</ul>
<p>would point to <code>localhost/site1/</code>, <code>localhost/site2/</code> etc.</p>
<p>Before using virtual hosts, I would just change my docroot to whatever project I was currently working on and would start ngrok like so</p>
<p><code>./ngrok http 8888</code> and it would launch and give me a random generated *.ngrok.io url.</p>
<p>My question is how do I specify the domain now since I am using virtual hosts?</p>

How to handle changing parquet schema in Apache Spark : <p>I have run into a problem where I have Parquet data as daily chunks in S3 (in the form of <code>s3://bucketName/prefix/YYYY/MM/DD/</code>) but I cannot read the data in AWS EMR Spark from different dates because some column types do not match and I get one of many exceptions, for example:</p>
<pre><code>java.lang.ClassCastException: optional binary element (UTF8) is not a group
</code></pre>
<p>appears when in some files there's an array type which has a value but the same column may have <code>null</code> value in other files which are then inferred as String types.</p>
<p>or</p>
<pre><code>org.apache.spark.SparkException: Job aborted due to stage failure: Task 23 in stage 42.0 failed 4 times, most recent failure: Lost task 23.3 in stage 42.0 (TID 2189, ip-172-31-9-27.eu-west-1.compute.internal):
org.apache.spark.SparkException: Failed to merge incompatible data types ArrayType(StructType(StructField(Id,LongType,true), StructField(Name,StringType,true), StructField(Type,StringType,true)),true)
</code></pre>
<p>I have raw data in S3 in JSON format and my initial plan was to create an automatic job, which starts an EMR cluster, reads in the JSON data for the previous date and simply writes it as parquet back to S3.</p>
<p>The JSON data is also divided into dates, i.e. keys have date prefixes. Reading JSON works fine. Schema is inferred from the data no matter how much data is currently being read.</p>
<p>But the problem rises when parquet files are written. As I understand, when I write parquet with metadata files, these files contain the schema for all parts/partitions of the parquet files. Which, to me it seems, can also be with different schemas. When I disable writing metadata, Spark was said to infer the whole schema from the first file within the given Parquet path and presume it stays the same through other files.</p>
<p>When some columns, which should be <code>double</code> type, have only integer values for a given day, reading in them from JSON (which has these numbers as integers, without floating points) makes Spark think it is a column with type <code>long</code>. Even if I can cast these columns to double before writing the Parquet files, this still is not good as the schema might change, new columns can be added, and tracking this is impossible. </p>
<p>I have seen some people have the same problems but I have yet to find a good enough solution. </p>
<p>What are the best practices or solutions for this? </p>

Hello, I need help on creating a Star Wars name generator using specific instructions. : I'm struggling with a specific method which takes in a String parameter. The promptString method will print its parameter to the user as a prompt, and then return a String that is the result of reading the console via the nextLine() method. For this program you will use nextLine() exclusively. I've prompted the user with a question using a parameter, and then used nextLine to read the string but after that im a bit lost how can i get the method to print to the console, i seem to only be able to return which only stores the string.
import java.util.*;
public class StarWarsName{
public static void main(String[]args){
promptString("Enter your first name: ");
}
public static String promptString(String n){
Scanner console = new Scanner(System.in);
String first = console.nextline();
return first.trim();

Passing an *os.File as an *io.Reader : <p>If there's a function that takes a *io.Reader, how would one pass an *io.File? This doesn't work:</p>
<pre><code>func somefunc(r *io.Reader){
}
func Test_FileReader(t *testing.T){
f, err := os.Open("xyz")
assert.NoError(t, err)
somefunc(&f)
}
</code></pre>
<p>It gives this error:</p>
<blockquote>
<p>Cannot use '&f' (type **File) as type *io.Reader</p>
</blockquote>
<p>Then, changing <code>*io.Reader</code>-><code>io.Reader</code> and <code>&f</code>-><code>f</code>, it compiles just fine:</p>
<pre><code>func somefunc(r io.Reader){
}
func Test_FileReader(t *testing.T){
f, err := os.Open("xyz")
assert.NoError(t, err)
somefunc(f)
}

<p>Is it even possible to pass an *os.File as an *io.Reader??</p>

What is the difference between @types.coroutine and @asyncio.coroutine decorators? : <p>Documentations say:</p>
<blockquote>
<p>@asyncio.coroutine</p>
<p>Decorator to mark generator-based coroutines. This enables the generator use yield from to call async def coroutines, and also
enables the generator to be called by async def coroutines, for
instance using an await expression.</p>
</blockquote>
<p>_</p>
<blockquote>
<p>@types.coroutine(gen_func) </p>
<p>This function transforms a generator
function into a coroutine function which returns a generator-based
coroutine. The generator-based coroutine is still a generator
iterator, but is also considered to be a coroutine object and is
awaitable. However, it may not necessarily implement the <code>__await__()</code>
method.</p>
</blockquote>
<p>So is seems like purposes is the same - to flag a generator as a coroutine (what <code>async def</code>in Python3.5 and higher does with some features).</p>
<p>When need to use <code>asyncio.coroutine</code> when need to use <code>types.coroutine</code>, what is the diffrence?</p>

Permutation of a value by another R studio : I am working in R Studio with a database that has these two variables. Camouflage and Detection. The values are binary, 0 for being conspicuous and 1 for being camouflaged. 1 for detected and 0 for undetected. However, during my analysis I added values that are called Unknown in the Detection variable. I would like to permute the Unknown with 1 then 0 and see if each of the permutations affects the significance of the glm that I am using. The permutation may be that all Unknown change to 0 or to 1, or that some change to 1 and others to 0. A random permutation. It may be simple, it's just that I am not really functional with R.

If you code in csharp, get a life, and please don't answer. c17 only - no broken stucts(not portable). here is my code. Compiles with no errors gcc 7.3, mingw 7.3. I replace gets and puts with safer functions and I still get garbage on windows. I assume this is a formatting issue...

Make a VStack fill the width of the screen in SwiftUI : <p>Given this code :</p>
<pre><code>import SwiftUI
struct ContentView : View {
var body: some View {
VStack(alignment: .leading) {
Text("Title")
.font(.title)
Text("Content")
.lineLimit(nil)
.font(.body)
Spacer()
}
.background(Color.red)
}
}
#if DEBUG
struct ContentView_Previews : PreviewProvider {
static var previews: some View {
ContentView()
}
}
#endif
</code></pre>
<p>It results in this interace:</p>
<p><a href="https://i.stack.imgur.com/B87Ym.png" rel="noreferrer"><img src="https://i.stack.imgur.com/B87Ym.png" alt="preview"></a></p>
<p>How can I make the <code>VStack</code> fill the width of the screen even if the labels/text components don't need the full width?</p>
<p>A trick I've found is to insert an <em>empty</em> <code>HStack</code> in the structure like so:</p>
<pre><code>VStack(alignment: .leading) {
HStack {
Spacer()
}
Text("Title")
.font(.title)
Text("Content")
.lineLimit(nil)
.font(.body)
Spacer()
}
</code></pre>
<p>Which yields the desired design:</p>
<p><a href="https://i.stack.imgur.com/XK2cY.png" rel="noreferrer"><img src="https://i.stack.imgur.com/XK2cY.png" alt="desired output"></a></p>
<p>Is there a better way?</p>

Grunt-eslint & enabling `--fix` flag to auto fix violations : <p>I know <code>eslint</code> CLI itself has a <code>--fix</code> flag, but I can't tell from the documentation how to use this via <code>eslintConfig</code> (in <code>package.json</code>) or in the grunt-eslint configuration in my Gruntfile.</p>

<pre><code>"env": {

Node NPM proxy authentication - how do I configure it? : <p>I'm new to Node and trying to install TypeScript using the following command:</p>
<pre><code>npm install -g typescript
</code></pre>
<p>I get the following error:</p>
<pre><code>if you are behind a proxy, please make sure that the 'proxy' config is set properly.
</code></pre>
<p>I have set my proxy using the following commands:</p>
<pre><code>npm config set proxy http://Username:Pa55w0rd@proxyhostname
npm config set https-proxy http://Username:Pa55w0rd@proxyhostname
</code></pre>
<p>and tried this also:</p>
<pre><code>npm config set proxy http://"ninjadev:5trongP@ssw0rd"@proxy.some-bigcorp.com
npm config set https-proxy http://"ninjadev:5trongP@ssw0rd"@proxy.some-bigcorp.com
</code></pre>
<p>But none of them work. I am working behind a copmpany proxy with authentication, so I think this is stopping me from connecting. I have added my username and password and this also didn't work.</p>
<p>Does anyone have any idea how I can connect to npm whilst using the company proxy and authentication?</p>
<p>Thanks</p>

Hot to tell Symfony http_client to read .htccess : I have a php application made in symfony, it needs this .htaccess to to work:
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
RewriteCond %{HTTP:Authorization} ^(.*)
RewriteRule .* - [e=HTTP_AUTHORIZATION:%1]
now I am writing some functional test and looks like the client can't find the controller for the route, this is the code:
$response = static::createClient()->request(
'POST',
'/api/login_check',
[
'body' => [
'username' => 'username',
'password' => 'secret123!#'
]
]
);
when I run the test I get this error:
2020-01-13T11:53:54+00:00 [error] Uncaught PHP Exception Symfony\Component\HttpKernel\Exception\NotFoundHttpException: "Unable to find the controller for path "/api/login_check". The route is wrongly configured." at /var/www/html/vendor/symfony/http-kernel/HttpKernel.php line 130
which is exactly the same error I use to have using postman before to add the .htaccess file.
Is there a way to make the http_client read the .htaccess file?
Or alternatively, how can I get rid of the .htaccess file?
thanks

JS/jQuery match two sets of arrays containing rgb color values using if/else : So I can create an array with rgb color values such as:
var atomArr = ['rgb(255, 255, 255)', 'rgb(255, 34, 0)', 'rgb(255, 34, 0)'];
With out going into details, I can even assign an object's background-color with a value from the array.
So why can't I take two similar arrays and check if both of them match (ordered match not necessary, but both arrays must contain the same values)?
In the example below, both arrays have the exact same values (not in order), but always triggers false.
var h2o = ['rgb(255, 255, 255)', 'rgb(255, 34, 0)', 'rgb(255, 34, 0)'];
function Check(A) {
var atomArr = ['rgb(255, 34, 0)', 'rgb(255, 255, 255)', 'rgb(255, 34, 0)'];
var i, j;
var totalmatches = 0;
for (i = 0; i < atomArr.length; i++) {
for (j = 0; j < A.length; ++j) {
if (atomArr[i] === A[j]) {
totalmatches++;
}
}
}
if (totalmatches == 3) {
console.log("true");
} else {
console.log("false");
}
}
Check(h2o);
Thank you for your time and help! | 0debug |

Java, JFrame, 3D Perspective in 2D Space : I'm working in Java with its JFrame. I want to be able to draw 3D objects like a cube.
But I have a problem, I don't know how to calculate the x and y position of where the vertices would go on the z axis.
I'm not working in OpenGL or anything, just using java's built in features.
I have the window set up and i'm able to draw lines, all I kneed to know to be able to get this to work is the calculation of where the position of vertices on the z axis would be placed in a 2D space.
Thank you in advance for any help! | 0debug |

Is there any easy way to merge two arrays in swift along with removing duplicates? : <p>Basically I need a version of <code>appendContentsOf:</code> which does not append <strong>duplicate</strong> elements.</p>
<p><strong>Example</strong></p>
<pre><code>var a = [1, 2, 3]
let b = [3, 4, 5]
a.mergeElements(b)
//gives a = [1, 2, 3, 4, 5] //order does not matter
</code></pre>

How to fix ,,Extraneous argument label 'input:' in call" and sigrabitTHREAD1 problem in swift : I'm building calendar app in swift. It has got a sigrbrtTHREAD1 problem and that strang mistake. Sorry for probably silly question but I'm completely beginner. Here is the code:
import UIKit
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
var wydarzenia = ["Wydarzenie1", "Wydarzenie2" ]
weak var input: UITextField!
weak var output: UILabel!
print(wydarzenia)
func show(_ sender: UIButton) {
print(wydarzenia)
}
func add(_ sender: UIButton) {
wydarzenia.append (input: String). !Extraneous argument label 'input:' in call!
}
}
}
}
