Converting String to Integer. Why this error? I want to change the ID (string) to IC (integer). Both are arrays. I'm still a beginner by the way. : #include <iostream>
#include <stdlib.h>
#include <cstring>
using namespace std;
int main(){
string ID[]={"620301025123"}; //ID array
long long int IC[10]={0}; //IC array
// loop to change the ID string to Array IC. I will want to increase the size of ID array, later on, to put in new data but for now, I'm just using one data which is "620301025123" first. */
for(int i = 0; i < 10; ++i){
IC[i]= {atoll(ID[i].c_str())};
}
}
/*The error I got is :

Firestore - Delete a field inside an object : <p>I'm using Firestore and I would like to delete a field that is in a specific object.
I can delete a field in a document thanks to : </p>
<pre><code>fieldName: firebase.firestore.FieldValue.delete()
</code></pre>
<p>But if I have an object like : </p>
<pre><code>songList {
songName1: "HelloWorld",
songName2: "AnotherSong",
songName3: "andTheLastOne"
}
</code></pre>
<p>In order to delete the field songName3, I won't be able to do something like : </p>
<pre><code>songList.songName3: firebase.firestore.FieldValue.delete()
</code></pre>
<p>Is there a way to delete a field inside an object ? Or should I delete the whole object, rebuild it without the 3rd field and save it ?</p>
<p>Thanks in advance,</p>

How to set up Travis CI and postgresql using custom db credentials? : <p>I'm trying to set up custom Postgres credentials with Travis CI as I'd like to avoid the existing credentials definition in the code to be tested.</p>
<p>The testing code defines that the database should be accessed on: </p>
<pre><code>'sqlalchemy.url': 'postgresql://foo:bar@localhost/testing_db'
</code></pre>
<p>I've therefore created a <code>database.travis.yml</code> file:</p>
<pre><code>postgresql: &postgresql
adapter: postgresql
username: foo
password: bar
database: testing_db
</code></pre>
<p>...and added the following to my <code>.travis.yml</code>:</p>
<pre><code>services:
- postgresql
before_script:
- psql -c 'create database stalker_test;' -U postgres
- mkdir config && cp database.travis.yml config/database.yml
</code></pre>
<p>However, I am still getting this during testing:</p>
<pre><code>OperationalError: (psycopg2.OperationalError) FATAL: role "foo" does not exist
</code></pre>
<p>What am I doing wrong?</p>

Scikit-learn, get accuracy scores for each class : <p>Is there a built-in way for getting accuracy scores for each class separatetly? I know in sklearn we can get overall accuracy by using <code>metric.accuracy_score</code>. Is there a way to get the breakdown of accuracy scores for individual classes? Something similar to <code>metrics.classification_report</code>.</p>
<pre><code>from sklearn.metrics import classification_report
from sklearn.metrics import accuracy_score
y_true = [0, 1, 2, 2, 2]
y_pred = [0, 0, 2, 2, 1]
target_names = ['class 0', 'class 1', 'class 2']
</code></pre>
<p><code>classification_report</code> does not give accuracy scores:</p>
<pre><code>print(classification_report(y_true, y_pred, target_names=target_names, digits=4))
Out[9]: precision recall f1-score support
class 0 0.5000 1.0000 0.6667 1
class 1 0.0000 0.0000 0.0000 1
class 2 1.0000 0.6667 0.8000 3
avg / total 0.7000 0.6000 0.6133 5

<p>Accuracy score gives only the overall accuracy:</p>

}
}
}
}
The client is succesfully transmitting the data to the server, and the server prints out the dictionary at once the data has been recieved for the purpose of error checking, yet when I try to access the key's corresponding value in the dictionary, it isn't there. Any help would be great.

automatically convert string to appropriate type : <p>I am trying to find a function to have python automatically convert a string to the "simplest" type. Some examples:</p>
<pre><code>conversion_function("54") -> returns an int 54
conversion_function("6.34") -> returns a float 6.34
conversion_function("False") -> returns a boolean False
conversion_function("text") -> returns a str "text"
</code></pre>
<p>R has a function called <a href="https://stat.ethz.ch/R-manual/R-devel/library/utils/html/type.convert.html" rel="nofollow noreferrer">type.convert</a> that does this. What is the way to do this in python? Is there an existing function or does one need to create a custom one?</p>

The problem is that in the column "Fertiliser" (strings) the amount of different types of fertiliser. The third number refers to manure. I want to create a new column which only the amount of manure (so then I can do regression analysis against yield).

Multiple aiohttp Application()'s running in the same process? : <p>Can two <code>aiohttp.web.Application()</code> objects be running in the same process, e.g. on different ports?</p>
<p>I see a bunch of examples of aiohttp code like:</p>
<pre><code>from aiohttp import web
app = web.Application()
app.router.add_get('/foo', foo_view, name='foo')
web.run_app(app, host='0.0.0.0', port=10000)
</code></pre>
<p>I'm wondering if there's some equivalent where multiple <code>web.Applications()</code> can be configured to run at the same time. Something like:</p>
<pre><code>from aiohttp import web
app1 = web.Application()
app1.router.add_get('/foo', foo_view, name='foo')
app2 = web.Application()
app2.router.add_get('/bar', bar_view, name='bar')
# This is the wishful thinking code:
web.configure_app(app1, host='0.0.0.0', port=10000)
web.configure_app(app2, host='0.0.0.0', port=10001)
web.run_apps()

Transitioning from sqlalchemy to postgres database : I've been using Flask with sqlalchemy but I've transitioned to setting up my own postgres databases and using psycopg2 to insert and return values from my databases. I was wondering how the classes in my Model.py should change now that I'm no longer using the databases set up by sqlalchemy and whether I need to set up a db object at all anymore.
Setting up a db object:
app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///' + os.path.join(basedir, 'data.sqlite')
app.config['SQLALCHEMY_COMMIT_ON_TEARDOWN'] = True
db.SQLALCHEMY(app)
A sample of a class in my Model file:
class User(UserMixin, db.Model):
__tablename__ = 'users'
id = db.Column(db.Integer, primary_key=True)
email = db.Column(db.String(64), unique=True, index=True)
username = db.Column(db.String(64), unique=True, index=True)
role_id = db.Column(db.Integer, db.ForeignKey('roles.id'))

Tensorflow: Multiple loss functions vs Multiple training ops : <p>I am creating a Tensorflow model which predicts multiple outputs (with different activations). I think there are two ways to do this:</p>
<p><strong>Method 1:</strong> Create multiple loss functions (one for each output), merge them (using <code>tf.reduce_mean</code> or <code>tf.reduce_sum</code>) and pass it to the training op like so:</p>
<pre><code>final_loss = tf.reduce_mean(loss1 + loss2)
train_op = tf.train.AdamOptimizer().minimize(final_loss)
</code></pre>
<p><strong>Method 2:</strong> Create multiple training operations and then group them like so:</p>
<pre><code>train_op1 = tf.train.AdamOptimizer().minimize(loss1)
train_op2 = tf.train.AdamOptimizer().minimize(loss2)
final_train_op = tf.group(train_op1 train_op2)
</code></pre>
<p>My question is whether one method is advantageous over the other? Is there a third method I don't know?</p>

PS - sorry if the code below has wrong indentations, as I am still getting used to stack overflow, they are correct in my program
username_chosen = input("Enter the username of the user for their details :")
with open("data.txt") as f:
for line in f:
if username_chosen in line:
print(line)
The loop I want is where the program keeps checking if there is a username as the one entered by the user and if there is not then it tells them error and prompts them to input again until the program can find the username.

How to make a mobile designed site appear similar on differn't screen resoloutions : <p>I am currently designing a mobile site, that would work perfectly on a 320x480 screen. The issue comes, as newer phones don't use that size anymore, and are much much bigger. (As I found out after I put all that effort in and read it on my phone.) I was wondering if there is any easy way to make it all expand the the proper size I would like it to look without going ahead and giving everything a view-width/vw or view-height/vh rating. (Nvm, I wonder how that would impact the font size.)</p>
<p>Or would I need to go ahead and do that, or something similar? (As it would be particularly bad if it wasn't mobile friendly, for a variety of reasons involving it's creation.)</p>

How to get the active tab In Angular Material2 : <p>I want to get which <a href="https://material.angular.io/components/component/tabs" rel="noreferrer">tab</a> is active. I tried to use a <code>@ViewChild</code> decorator and accessing the element properties that way, but it returns <code>null</code>.</p>
<p><strong>Component:</strong></p>
<pre><code>import {Component, OnInit, ViewChild} from '@angular/core';
@Component({
selector: 'material-app',
template: `
<md-tab-group #tabGroup>
<md-tab label="Tab 1">Content 1</md-tab>
<md-tab label="Tab 2">Content 2</md-tab>
</md-tab-group>
`
})
export class AppComponent implements OnInit {
@ViewChild('tabGroup') tabGroup;
constructor() {
}
ngOnInit() {
console.log(this.tabGroup); // MdTabGroup Object
console.log(this.tabGroup.selectedIndex); // null
}
}

regex / heuristic to detect repetitive junk words like "gfgfgfgf" "dadadada" "sdsdsd" etc : searching for this solution proved to be a bit hard to find, so I'm forced to ask the question.
**First, a bit of a background story:**
- I run a blog
- I have a post about **reCaptcha**
- Sometimes (every week or so) someone tries to be funny and posts spam comments in the similar form to this:
>gfgfgfgf
>sdsdsdsds
>dadadada
You get the idea. Are they testing an automated reCaptcha bypass systems as a proof of concept or just trying to be funny, I don't know and I don't really care (most probably a mix of both).
(edit) Interestingly enough, no other posts are affected by this type of spam comments.
However, thinking about this, it should be relatively simple and easy to detect patterns in the (mostly) single words which those comments have (99%) and prevent those comments from posting. Sounds simple?
But, it must also be good enough to avoid false positives.
If, for example, a comment has single repetitive word like above, then it's definitely a spam.
If, on the other hand, it just has a typo in the middle of the normal sentence, it should pass.
Now, I can already 'hear' comments below why not use Akismet. Or solution X. Or solution Y. Why not external comments system like **Disqus** or **Facebook comments**. Because, I can't. It must be in-house. And I wish to be simple. I already have some things that prevent a lot of junk, but for this particular case they all fail.
**Solution(s) that I have tested so far:**
This is one regex example that is a variant of this answer [here][1], but it's not perfect:
(.+\w)(?=\1+)/gu
**[see live regex101 example][2]**
Problems with it is that in examples below it will pass most of the time, but it will trigger false positives, too:
correct/proper detection:
> 123123123123
> daddaddaddad
> sadsadasad
> sadsadsad
> 121212121
> sasasasasas
> sdsdsdsds
> dsdsdsdsd
> ffffffff
> blahblah
> ioiooioioioi
> popopopopop
> Hi I dont think this is a spam.
improper/incorrect detection (false positive):
> I loooovve this. It's awesooooommeee!
Now, this is tricky. The filter does exactly what it was instructed to do, however, "ooovv" and "oooommeee" patterns are not exactly repetitive in the same sense like the first ones listed above ("gfgfgfgf" etc.) - filter detect "oo" pattern repetition. Yes, it is correct, but not exactly what I want to target.
Does anyone have an idea how can I improve this regex detection to be smarter a bit?
One thought / idea that I have is outside of the regex itself, and that is to let pass single repetitions IF comment contains more than 1 word (e.g. something closer to a full sentence). But, I'd like the case where actual repetition can be differentiated, such as in the case of "awesoooommeee" word.
Thanks!

C++ error, compiler won't recognize string::push_back : <p>The function it has an issue with:</p>
<pre><code>string encode (string message, string key) {
string code = "whatever";
string forst;
int num;
string::size_type begin = 0;
message = lower_and_strip(message);
for (char val : message) {
num = return_encoded_char(key, begin, val);
forst = to_string(num);
code.push_back(forst); //*******************************
}
return code;
}
</code></pre>
<p>The starred line is what it points to. The return_encoded_char function returns an integer. </p>
<p>The specific error is
<code>proj05.cpp:68:23: error: no matching function for call to 'std::basic_string<char>::push_back(std::string&)'</code> and points to the line I starred.</p>
<p>I initially just declared <code>code</code> without initializing it, but changing that didn't fix it. All the similar questions I could find had some other element to blame; I feel like this should be relatively straightforward, though obviously it's not since it isn't working. </p>
<p>I have <code>#include <stream></code> and <code>using std::to_string</code> etc. I'm using -std=c++11 to compile it.</p>

Easiest way of building up visual representation of a graph data structure : <p>I need some suggestions for a libraries or other tools that I can use. I have a graph data structure built up of class objects each having its children (again objects of the class) in a list variable. I need a quick and easy way to draw these nodes, color them or change the shape of the nodes depending upon various conditions for visualization and proof of concept purposes. Since this is not the primary motive of the program and something that needs to be on the side, it doesn't matter if its an ugly method, it just needs to be hassle free. I have conisdered using graphviz for this but would be open to suggestions as I may have to make changes to the color/shape of the nodes while traversing the tree again and again.</p>

</ul>
<p>Problem: I want to subtract TotalPrize for the list above (1-> 2-> 3 ...) so that Workers gets the full prize by order Prioritize:</p>
<ul>
<li>John: 1000 (full)</li>
<li>Andy: 2000 (full)</li>
<li>Bill: 2200 (full)</li>
<li>Carry: 1900 (the list above, Carry must be 3100, but because TotalPrize = 7100 has been divided in advance for the first three remaining 1900)</li>
<li>Asawa: 0 (because all the money for the first 4 people was divided)</li>

Quickest way to turn off the delete option in swipe to delete in Xcode 8 : Hello fellow programmers, I know all about the swipe to delete with table view function, but what would be the easiest way to have an image view simply swipe to delete with the delete option not opening on the side, but simply deleting right away. I have done some looking but I can't find a good answer, thanks for the help.

TensorFlow: How to ensure Tensors are in the same graph : <p>I'm trying to get started with TensorFlow in python, building a simple feed-forward NN. I have one class that holds the network weights (variables that are updated during train, and are supposed to remain constant for runtime) and another script to train the network, which gets the training data, separates them to batches and trains the network in batches.
When I try to train the network, I get an error indicating that the data tensor is not in the same graph as the NN tensors:</p>
<blockquote>
<p>ValueError: Tensor("Placeholder:0", shape=(10, 5), dtype=float32) must be from the same graph as Tensor("windows/embedding/Cast:0", shape=(100232, 50), dtype=float32).</p>
</blockquote>
<p>The relevant parts in the training script are:</p>
<pre><code>def placeholder_inputs(batch_size, ner):
windows_placeholder = tf.placeholder(tf.float32, shape=(batch_size, ner.windowsize))
labels_placeholder = tf.placeholder(tf.int32, shape=(batch_size))
return windows_placeholder, labels_placeholder
with tf.Session() as sess:
windows_placeholder, labels_placeholder = placeholder_inputs(batch_size, ner)
logits = ner.inference(windows_placeholder)
</code></pre>
<p>And the relevant in the network class are:</p>
<pre><code>class WindowNER(object):
def __init__(self, wv, windowsize=3, dims=[None, 100,5], reg=0.01):
self.reg=reg
self.windowsize=windowsize
self.vocab_size = wv.shape[0]
self.embedding_dim = wv.shape[1]
with tf.name_scope("embedding"):
self.L = tf.cast(tf.Variable(wv, trainable=True, name="L"), tf.float32)
with tf.name_scope('hidden1'):
self.W = tf.Variable(tf.truncated_normal([windowsize * self.embedding_dim, dims[1]],
stddev=1.0 / math.sqrt(float(windowsize*self.embedding_dim))),
name='weights')
self.b1 = tf.Variable(tf.zeros([dims[1]]), name='biases')
with tf.name_scope('output'):
self.U = tf.Variable(tf.truncated_normal([dims[1], dims[2]], stddev = 1.0 / math.sqrt(float(dims[1]))), name='weights')
self.b2 = tf.Variable(tf.zeros(dims[2], name='biases'))
def inference(self, windows):
with tf.name_scope("embedding"):
embedded_words = tf.reshape(tf.nn.embedding_lookup(self.L, windows), [windows.get_shape()[0], self.windowsize * self.embedding_dim])
with tf.name_scope("hidden1"):
h = tf.nn.tanh(tf.matmul(embedded_words, self.W) + self.b1)
with tf.name_scope('output'):
t = tf.matmul(h, self.U) + self.b2
</code></pre>
<p>Why are there two graphs in the first place, and how can I ensure that data placeholder tensors are in the same graph as the NN?</p>
<p>Thanks!!</p>

So can anybody please help me me how do i find respective region from this statistics array??

Chrome - Debug Angular/Typescript - how to navigate to ts file : <p>To debug my angular front end, I open the dev tools in Chrome and the sources tab and navigate to the ts file by clicking down through all the folders and when I do find the ts file, I then set a breakpoint. and go back to using the application and then start debugging.</p>
<p>While this works, it is time consuming to have to drill down through folders... and look for the ts file. As the project has grown, I find it is becoming even more time consuming.</p>
<p>I also have to remember which TS file is associated with which page.</p>
<p>Does anyone know if it is possible to go directly from the page to the ts file ?</p>
<p>I would love to be able to right click and select a menu item to go directly to the ts file in exactly the way Inspect works for HTML files.</p>
<p>Any suggestions should consider that the project is quite large.
I did try to use some add-on but it took ages to refresh was unusable.</p>
<p>Does anyone have any tips on how to avoid drilling down through the folders to find the ts file and setting the breakpoint. How can this be achieved in a much faster, efficient way ?</p>
<p>Thanks a million,
Fergal.</p>

How to validate a JWT token : <p>I'm trying to use JWT tokens. I managed to generate a valid <code>JWTTokenString</code> and validated it on the <a href="https://jwt.io/" rel="noreferrer">JWT debugger</a> but I'm having an impossible time validating the token in .Net. Here's the code I have so far:</p>
<pre><code>class Program {
static string key = "401b09eab3c013d4ca54922bb802bec8fd5318192b0a75f201d8b3727429090fb337591abd3e44453b954555b7a0812e1081c39b740293f765eae731f5a65ed1";
static void Main(string[] args) {
var stringToken = GenerateToken();
ValidateToken(stringToken);
}
private static string GenerateToken() {
var securityKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(key));
var credentials = new SigningCredentials(securityKey, SecurityAlgorithms.HmacSha256);
var header = new JwtHeader(credentials);
var payload = new JwtPayload {
{ "some ", "hello "},
{ "scope", "world"},
};
var secToken = new JwtSecurityToken(header, payload);
var handler = new JwtSecurityTokenHandler();
return handler.WriteToken(secToken);
}
private static bool ValidateToken(string authToken) {
var tokenHandler = new JwtSecurityTokenHandler();
var validationParameters = GetValidationParameters();
SecurityToken validatedToken;
IPrincipal principal = tokenHandler.ValidateToken(authToken, validationParameters, out validatedToken);
Thread.CurrentPrincipal = principal;
return true;
}
private static TokenValidationParameters GetValidationParameters() {
return new TokenValidationParameters() {
//NOT A CLUE WHAT TO PLACE HERE
};
}
}
</code></pre>
<p>All I want is a function that receives a token and returns true or false based on its validity. From research I've seen people use <code>IssuerSigningToken</code> to assign the validation key. But when I try to use it, it doesn't seem to exist. Could anyone give me a hand on validating the token?</p>

Split string on one use of a word and not the other : <p>fairly novice here, I'm looking for an effective way to use split() to split a string after a certain word.
I'm working on a voice controlled filter using the Csound API in python, and say my input command is "Set cutoff to 440", I'd like to split the string after the word "to", basically meaning that I can say the command however I like and it'll still find my frequency I'm looking for, I hope that makes sense.
So at the moment, my code for this is</p>
<pre><code>string = "set cutoff to 440"
split = string.split("to")
print(split)
</code></pre>
<p>and my output is</p>
<pre><code>['set', 'cu', 'ff', '440']
</code></pre>
<p>The problem is the 'to' in 'cutoff', I know I could fix this by just changing cutoff to frequency but it seems like giving in too easily. My suspicion is there's a way to do this with regular expressions, but I could easily be wrong, any advice would be really helpful, and I hope my post adhered to all the guidelines and stuff, am pretty new to Stack Overflow. </p>

C# string.split variances : <p>I have probably missed something very basic but this has me stumped.</p>
<p>When using String.Split() I get different results between </p>
<pre><code>.Split(' ')
</code></pre>
<p>and </p>
<pre><code>.Split(new char[' '])
</code></pre>
<p>Given this code:</p>
<pre><code>using (System.IO.StreamWriter sw = new StreamWriter(@"C:\consoleapp1.log", true))
{
string anystring = "pagelength=60 pagewidth=170 cpi=16 lpi=8 landscape=1 lm=2";
sw.WriteLine(".Split(' ')");
string[] anystrings1 = anystring.Split(' ');
for (int i = 0; i < anystrings1.Length; i++)
{
sw.WriteLine($@"{i,2}: {anystrings1[i]}");
}
sw.WriteLine(".Split(new char[' '])");
string[] anystrings2 = anystring.Split(new char[' ']);
for (int i = 0; i < anystrings2.Length; i++)
{
sw.WriteLine($@"{i,2}: {anystrings2[i]}");
}
}
</code></pre>
<p>Why do I get different results:</p>
<pre><code>.Split(' ')
0: pagelength=60
1: pagewidth=170
2: cpi=16
3: lpi=8
4: landscape=1
5: lm=2
.Split(new char[' '])
0: pagelength=60 pagewidth=170 cpi=16 lpi=8 landscape=1 lm=2

Split the character vector into two parts : <p>Consider the following character vector of the length 1:</p>
<pre><code>l <- "http://www.idealo.de/preisvergleich/OffersOfProduct/4983410_-iphone-se-64gb-spacegrau-apple.html"
</code></pre>
<p>I desire to split it into two parts, so that the first part should be:</p>
<pre><code>p1 <- "http://www.idealo.de/preisvergleich/OffersOfProduct/4983410"
</code></pre>
<p>and the second one:</p>
<pre><code>p2 <- "_-iphone-se-64gb-spacegrau-apple.html"
</code></pre>
<p>Surely, one must use regexp to solve the problem. Please could you give me some insight where I can learn manipulation with regular expressions easily. For any help I will be sincerely thankful.</p>

Why will this array not stop looping in c : <p>I am trying to display a <a href="http://pages.mtu.edu/~shene/NSF-4/Tutorial/VIG/Vig-Base.html" rel="nofollow noreferrer">Vigenere Square</a> but the for loop that creates it will not stop looping past the counter. You can find the loop under choice 1. Also if someone knows how to make the decrypt function to work.</p>
<pre><code>#include <stdio.h>
#include <stdlib.h>
#include <string.h>
char encrypt(char, char);
char decrypt(char, char);
int main()
{
int choice;
printf("What would you like to do?\n\n");
printf("1. Show board\n");
printf("2. Encrypt\n");
printf("3. Decrypt\n");
printf("4. Exit\n");
scanf("%i", &choice);
while(choice != 4){
char key[9];
char input[51];
char decrypt[51];
if (choice == 3 || choice == 2){
printf("Give me a 9 character or less key in caps.\n");
scanf("%s", &key);
printf("Give me a 51 character or less string in caps.\n");
scanf("%s", &input);
}
if (choice==1){
int i, j;
for(i=0;i<=25;i++){
for(j=0;j<=25;j++){
