Is this nested function problem solvable in C? : <p>Given g(x) = cos(log(2.21-x)) and that x = 0.99, estimate the value given by the nested g(g(g(x)... equation as the nesting approaches infinity (you don't have to actually go to infinity, but just set up a way to recurse this nesting n times or so).</p>
<p>I've tried some basic stuff like g(x) = cos(log(2.21-x))
and then creating a for loop defined by g(x) = g(g(x)). None of this works. </p>
<p>In these attempts I've gotten end of void errors and overflow errors. If anyone can figure out if this question is viable in C, even though C doesn't support "nested" functions, I will be amazed and very thankful.</p>

Matplotlib scatter plot with unknown error : <p>I am attempting to create a scatter plot. I have a list of numbers from 0 - 17 as well as an array with 18 values. I can plot the data as a line plot but when I try to plot as a scatter I get an error message I do not understand: <code>TypeError: ufunc 'sqrt' not supported for the input types, and the inputs could not be safely coerced to any supported types according to the casting rule ''safe''</code></p>

Fisher exact test taks so long in R :( : My table has 770,000 rows and
what I did is
> mydata <- dbGetQuery(mydb, "select * from table")
> mydata$pvalue <- apply(as.matrix(mydata[, c(3,5,4,6)]), 1, function(x) fisher.test(matrix(x, nrow=2))$p.value)
to get pvalues.
But it takes so long. (it has been over 24hours and it is still running)
Should I use other method?

Sort data in python, such that missing data points are filled with NaNs : In the metaanalysis of a drug interference study, I am analyzing the influence on patients of drugs at several concentations at different time points.
Now for some patients, data are available for only some of the drug concentrations.
I use a vector as follows to filter the data for each patient by available drug concentrations:
vec_conc = ['none','1nM','10nM','100nM','1uM','10uM','100uM']
When enumerating over this "concentration vector", obviously 0 = none, 1 = 1nM, ..., 4 = 1uM, ..., 6 = 100uM.
My script so far returns arrays "influence" for each patient (e.g. below), where influence[i,0] are the above mentioned "concentration counts" and [i,1:] are the results at concentration i for the various time points.
E.g. in the following patient, data only for concentations 0, 2, 3, 5 are available:
[[ 0. 1. 0.73475787 0.36224658 0.08579446 -0.11767365
-0.09927562 0.17444341 0.47212111 1.00584593 1.69147789 1.89421069
1.4718292 ]

Now, for my later metaanalysis of all patients I would like to have the "influence" arrays to have all NaNs included for missing concentrations.
In the above example, I would like to have

To re-sort my influence vectors I have tried the following:
influence_incl_missing = np.ones((len(vec_conc),len(results)+1))
for i, conc in enumerate(vec_conc):
if i == influence[i,0]:
influence_incl_missing[i,:] = influence[i,:]
else:
influence_incl_missing[i,1:] = np.full(len(results),np.nan)
influence_incl_missing[i,0] = i
This gives me the obvious error
IndexError: index 4 is out of bounds for axis 0 with size 4
since len(influence) < len(vec_conc).
How can I do this in python?
Many thanks!!

How to get string / line between 2 strings using Regex in C# : I am bit new for Regex class in C#. I have use case like I have some file where we have data in following format :--
----string1
abc
cde
--string1
efg
hjk
-string1

string1
Now when I am using like string1(.+?)string1 as pattern I am getting following 2 result :--
"abc", cde and xyz.
But I want abc, cde, efg, hjk and xyz.
Can you suggest how can I do it ?
There is one more issue - how to handle variable numbers of "-" as right now I am ignoring it (in my above example) but I have to handle it later on.
Thanks for help.

remove unnecessary white space, auto detect header, and sorted by name in datagrib from csv file. C# : I know my title is confuse and not clear, now i going to explain what i need.<br/>
In the end of the program, it will be able to input csv file, calculate and output the result.<br/>
For now i m doing it step by step.<br/>
**1)** Able to import csv to datagribview (done)<br/>
**2)** Remove unnecessary white space, sort it by name (in progress) <br/>
**3)** Calculation <br/>
To makes my question clear and easy to understand, here is the csv file sample.

As you can see that there are repeated 'lotID' is every section, and 2 type to lotID.
And here is what i have done so far. let's call this pic a.I successfully filter out lotID of the 1st type lotID.
[![enter image description here][2]][2]
this is pic B , as u can see the 'LotID' of section type of lot ID is appear again in each section[![enter image description here][3]][3]

As you can see in PIC A, the lotID of each section is not repeated, and it white space appear in each section.<br/>
This is the first thing i try want to fix.<br/>
Secondly, i want to filter out the 'LotID' header of second type lotid.<br/>
Here is the code.<br/>
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.IO;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

{
List<string[]> rows = File.ReadLines(openFile.FileName).Select(x => x.Split(',')).ToList();
DataTable dt = new DataTable();
List<string> headerNames = rows[0].ToList();
foreach (var headers in rows[0])
{
dt.Columns.Add(headers);
}
foreach (var x in rows.Skip(1))
{
if (x.SequenceEqual(headerNames)) //linq to check if 2 lists are have the same elements (perfect for strings)
continue; //skip the row with repeated headers
dt.Rows.Add(x);
}
dataGridView1.DataSource = dt;
}
}
private void Form1_Load_1(object sender, EventArgs e)
{
openFile.Filter = "CSV|*.csv";
}
}
}
I hope that my question can helps the other if they having same problem like me too! <br/>

i want to add 10% service tax and 13 % vat but i am unabble to do so please anybody help me. Beside this i have to print the bill for 5 users : You are required to create an MVP (Minimal Viable Product) to take customer orders for a local ethnic food restaurant in Kathmandu. The restaurant offers 10 different types of food dishes, taken from the local ethnic food culture. The restaurant operates with limited dishes and limited staff. You are required to create a prototype of order taking system to ease the working process within the restaurant. Your program should have the following functionalities:
• The program should display the menu at the start (with 10 dishes)
• Each customer will make an order based on the menu shown. For each order, the system should calculate the total bill.
• For each bill, after adding the sum total of the prices of the dishes, the sum total would be subject to 10% service Tax and 13% VAT.
• For every new instance where a customer (new or repeating) makes an order, a new bill is generated.
• Altering a confirmed order would not be a necessary feature for the MVP phase of the system.
• Your MVP should be able to manage order and billing of 5 customers at once.
• The menu prices and the dishes in them could be initially hardwired into your MVP for test purposes (in a file or an array)
public class Array { //class name

int choice;

in C how to pass local function variable value to another function and print value without errors : <pre><code>#include <stdio.h>

</code></pre>
<p>Ive started to code in C recently in Ubuntu
im trying to return the value a local variable of one function and have it passed to another
function. I have read that since local variables are assigned to stack the value will no longer
exist after function returns, and that I have to allocate memory in heap using malloc.</p>
<p>when I compile I get this warning: </p>
<pre><code>initialization makes integer from pointer without a cast
[-Wint-conversion] int ipt = malloc(sizeof(int));
</code></pre>
<p>when I adjust this to int ipt = (int)malloc(sizeof(int)); -I get:</p>
<pre><code>warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
int ipt = (int)malloc(sizeof(int));
</code></pre>
<p>What is the correct thing to do here?</p>
<p>I'm also having trouble with scanf since I switched to coding in Ubuntu.
I tried a different way, trying to use pointers:</p>
<pre><code>#include <stdio.h>
#include <stdlib.h>
int* give_options();
int* give_options(){
printf("===== MENU 1 =====\n");
printf("> store new customer :\t\tenter 1\n");
printf("> view a customer :\t\tenter 2\n");
printf("> view all customers :\t\tenter 3\n");
printf("> exit program :\t\tenter 4\n ");
int* ipt;
ipt = malloc(sizeof(int));
scanf("d",&ipt);
return ipt;
}
int main(){
int* dec = give_options();
printf("decision is: %d", dec);
getchar();
}
</code></pre>
<p>compiling this gives me following errors:</p>
<pre><code>warning: format ‘%d’ expects argument of type ‘int *’, but argument 2 has type ‘int **’ [-Wformat=]
scanf("%d",&ipt);
warning: format ‘%d’ expects argument of type ‘int’, but argument 2 has type ‘int *’ [-Wformat=]

<li>Publish an event detailing the changes on the global message bus.</li>
</ol>
<p>But what if, for example, a power outage occurred in-between Steps 1 and 2? In a naively-built system, that would mean the changes persist but the event detailing them will never be published. I've pondered the following ideas to create better guarantees, but I'm not quite sure of all the pros and cons of each:</p>
<p>A: Use an embedded database (like SQLite) in my microservice instance to track the full transaction, from the commit to the main database to the event publishing.</p>
<p>B: Create an Events table in my main database, using database transactions to insert the Event and commit the relevant changes at the same time. The service would then push the Event to the bus, and then make another commit to the main database to mark the Event as Published.</p>
<p>C: As above, create an Events table in my main database, using database transactions to insert the Event and commit the relevant changes at the same time. Then, notify (either manually via REST/Messages from within the service or via database hooks) a dedicated EventPusher service that a new event has been appended. The EventPusher service will query the Events table and push the events to the bus, marking each one as Published upon acknowledgement. Should a certain amount of time pass without any notification, the EventPusher will do a manual query.</p>
<p>What are the pros and cons of each of the choices above? Is there another superior option I have yet to consider?</p>

Losing widget state when switching pages in a Flutter PageView : <p>I have a series of stateful widgets in a PageView managed by a PageController. I am using <code>pageController.jumpToPage(index)</code> to switch pages. When switching pages all state appears to be lost in the widget, as if it was recreated from scratch. I have tried using <code>keepPage: true</code> in the PageController but that doesn't seem to have any effect. Is this the intended behavior of a PageView or am I doing something wrong? Any suggestions appreciated, thanks!</p>

With knexjs, how do I compare two columns in the .where() function? : <p>Using knexjs only (no bookshelf) I would like to do something like the following query:</p>
<pre><code>select * from table1 where column1 < column2
</code></pre>
<p>However, when I do this:</p>
<pre><code>.table("table1").select().where("column1", "<", "column2")
</code></pre>
<p>The SQL that knexjs generates is:</p>
<pre><code>select * from table1 where column1 < 'column2'
</code></pre>
<p>Which doesn't give the desired result b/c it's not comparing the value from the column, it's comparing the value of the string, 'column2'.</p>
<p>Anyone know how to do what I'm wanting? Thanks!</p>

Disable Upgrade-Insecure-Requests in Firefox and Chrome : <p>I run a PHP+Apache2 application locally - for development purposes.</p>
<p>The app is running at <a href="http://x.dev" rel="noreferrer">http://x.dev</a> (a virtual host + an entry in hosts file)</p>
<p>After Firefox updated it seems that I can no longer access <a href="http://x.dev" rel="noreferrer">http://x.dev</a> as the address in address bar is changed, by the browser, in <a href="https://x.dev" rel="noreferrer">https://x.dev</a> which obviously is not configured.</p>
<p>I used older version of Firefox (49) vs the new one (59.0.2) and the difference seems to be a new header "Upgrade-Insecure-Requests" that was added to the request.</p>
<p>This seems to force http to https, thus causing an issue.</p>
<p>Bellow is what I got after I try to access <a href="http://x.dev" rel="noreferrer">http://x.dev</a> :</p>
<p><a href="https://i.stack.imgur.com/4tvwO.jpg" rel="noreferrer"><img src="https://i.stack.imgur.com/4tvwO.jpg" alt="enter image description here"></a></p>
<p>I saw the same behavior in Chrome. Edge seems to not be "plagued" by this one.</p>
<p>AFAIK this new header was added to improve security (I'm fine with that), but is there any method (configure Firefox) to get back to old behavior (not sending this value)? Or any change on server side to ignore that request?</p>

Will it be possible to annotate lambda expression in Java 9? : <p><a href="https://stackoverflow.com/questions/22375891/annotating-the-functional-interface-of-a-lambda-expression">This question</a> is now over 3 years old and specifically addressed Java 8, with the accepted answer also citing the <a href="http://download.oracle.com/otndocs/jcp/java_se-8-fr-eval-spec/index.html" rel="noreferrer">Java SE 8 Final Specification</a>.</p>
<p>I would be interested if something regarding this question will change in Java 9: Is there any way to annotate a lambda expression similar to annotating a corresponding anonymous class?</p>
<hr>
<p><strong>Example:</strong></p>
<p>Annotation:</p>
<pre><code>@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.TYPE_USE)
public @interface MyTypeAnnotation {
public String value();
}
</code></pre>
<p>Working annotation of anonymous class:</p>
<pre><code>Consumer<String> consumer = new @MyTypeAnnotation("Hello ") Consumer<String>() {
@Override
public void accept(String str) {
System.out.println(str);
}
};
</code></pre>
<p>Annotating a lamba expression, currently not working in Java 8:</p>
<pre><code>Consumer<String> myAnnotatedConsumer = @MyTypeAnnotation("Hello") (p -> System.out.println(p));
</code></pre>

Complier cannot find .h files (code blocks) : Hey all I am trying to include a few libraries in code blocks, however when I add the path of the .h files to the search directory, it only seems to identify the ones in the main file and I think that is due to the fact that in the main file they are included as such (for example) #include "qtcpsocket.h", whereas in the .h file they are included as (for example) #include <QtNetwork/qabstractsocket.h>.
Apart from the fact that one includes the folder in which it is located, what is the major different? Why it may not work? and what do it need to do to change it?
one more thing i'm sure the file are in the folder.
Here are a few code snippets if this helps

Writing a numpy matrix to a text file : I am trying to write a numpy array to a text file. But it deos not work. My problem follows.
I am trying to get the RGB pixel values of a picture using `matplotlib.image` and save the values obtained from my program to some file for future use.
The values are returned in the form of an array, which I tried to write to a text file using the following code. But the file does not open. Nor does it show an error message.
import matplotlib.pyplot as plt
import matplotlib.image as mpimg
import numpy as np
img=mpimg.imread('kitten5.jpeg')
print(img)
f=open('kitten.dat','w')
f.write(img)
f.close()
imgplot=plt.imshow(img)
plt.show()
Can someone help? It is not mandatory that the data has to be saved to a text file alone. Other suggestions are equally welcome.

Is there a way to change the CSS resize corner's position? : <p>So this is a bit of a strange question. Programming a web application with a resizable div. I'm using the CSS resize property at the moment as it seemed like it was the easiest way to do it. The problem is my box has a locked bottom and left position (which I want to maintain), but the resize corner chosen by default is the lower right one, which produces weird results for resizing the top. Looked around online but couldn't find a way to move that corner to the upper right instead of the bottom right. Any advice on how to produce this result? Also not opposed to using a different method of resizing. Here's the current style being applied to the box:</p>
<pre><code>display: block;
font-size: 9pt;
position: absolute;
bottom: 50px;
left: 20px;
padding: 10px;
min-height: 0;
min-width: 0;
border: solid 1px black;
width:400px;
height:400px;
resize: both;
overflow-x: auto;
overflow-y: hidden;
</code></pre>
<p>And here's a picture of the div in question with the corner that currently has the resize tool on it boxed. Any advice would be greatly appreciated. I'm more than happy to elaborate on things I might've missed as well. Thanks! </p>

Regex for nested pattern : <p>I have a pattern like this:</p>
<pre><code>#alphanumericX(anythingY){
anythingZ
}#
</code></pre>
<p>It can be nested like this:</p>
<pre><code>#alphanumeric1(anything1){
#alphanumericX(anythingY){
anythingZ
}#
}#
</code></pre>
<p>Or like this:</p>
<pre><code>#alphanumeric1(anything1){
anything2
#alphanumericX(anythingY){
anythingZ
}#
}#
</code></pre>
<p>The patterns can be written not just once, but multiple like this:</p>
<pre><code>#alphanumericX(anythingY){
anythingZ
}#
#alphanumeric1(anything1){
anything1
}#
</code></pre>
<p>I want a regex to match the the patterns above, so it will return like this:</p>
<pre><code>#alphanumericX(anythingY){
anythingZ
}#
</code></pre>
<p>How to achieve that?</p>
<p>Here is my current regex: <code>/#(.*?)\((.*?)\)\{(.*?)\}#/sm</code></p>

<p>Pay attention, that same solution works ok using <em>DevExpress 15.2.7</em> so it's some kind of breaking changes between two versions.</p>
<p>Same solution also works in current version when report is set directly to <code>AspxDocumentViewer.Report</code> (not using <code>ReportServiceClientFactory</code> and <code>ReportService</code>), so it seems to be a <code>ReportService</code> issue.</p>

<p>I want Flux publish on-demand (e.g. when something happens). All the example I found is to use Flux.interval to periodically publish event, and there seems no way to append/modify the content in Flux once it is created.</p>

Final variable in java : <pre><code> class Test {

Test.x = 42;
}
}
</code></pre>
<p>I have declared a static final variable, and when i compiled it the following error shown up.</p>
<pre><code> error: cannot assign a value to final variable x
Test.x = 42;
</code></pre>
<p>i think i have reached to the solution but i want to check if i am right or not?</p>
<p>I know that a static variable if not initialized is provided a default value. As it is a static final int variable it will be assigned a value of 0. later on, i tried to change the value to 42 which is not possible because the variable is final and cannot be changed from 0.</p>
<p>am i right or is there some other answer to it?</p>

I have incremented the database version number and have also uninstalled and reinstalled the app which gives me the same error.
Also I am trying to create a one to many relationship from "PrimaryLocation" table to "TrainingSet" table. For this purpose, I have added a foreign key relationship while creating the second table(which I have commented out). Is the syntax correct?
Any help would be appreciated. Thanks in advance.

what is the meaning of init method in objective c? : i am new in objective c and from java background, i want to know what is the meaning of `init()` method/function in objective c in a base class while achieving inheritance ?
Is this is a kind of constructor like in java ? and is this is essential to use only `init()` method for creating and using objects? can we use other methods also instead of using `init()`.
and at last why is the return type of the `init()` is `id` ?

simple Logistic regression : everyone, i tried to solve a simple linear regression problem of two-dimensional classification.
Here I have a feature matrix X_expanded, which has a shape of [826,6], To classify objects we will obtain probability of object belongs to class '1'. To predict probability we will use output of linear model and logistic function.
And here is the function of compute probability.
def probability(X, w):
"""
Given input features and weights
return predicted probabilities of y==1 given x, P(y=1|x), see description above
Don't forget to use expand(X) function (where necessary) in this and subsequent functions.
:param X: feature matrix X of shape [n_samples,6] (expanded)
:param w: weight vector w of shape [6] for each of the expanded features
:returns: an array of predicted probabilities in [0,1] interval.
"""
# TODO:<your code here>
X = X_expanded
m = X.shape[0]
w = np.zeros((m,1))
Z = np.dot(w.T,X)
P = 1./(1+np.exp(-Z))
return P
For a simple test:
dummy_weights = np.linspace(-1, 1, 6)
ans_part1 = probability(X_expanded[:1, :], dummy_weights)[0]
But it always returns array([ 0.5, 0.5, 0.5, 0.5, 0.5, 0.5]).
Any Suggestion? Thank you very much.

How to provide user login with a username and NOT an email? : <p>I'd like to use Firebase for my web app that is for people with dementia in a care home. They do not have email or social network accounts so will need a simple username / password sign up / sign in.</p>
<p>What is the easiest way to do this? From what I can see in the docs I'd have to use a custom auth flow but I do not have an existing auth server.</p>
<p>If I do need ot do this what is the easiest way to provide the token? In Azure there is Functions and AWS has Lambda but I see nothing here is Firebase</p>

failed to download file from mysql server : I am new with JSP and servlets. Please help me with my problem. I have done code for uploading multiple files to MySQL database and it is successful. I have one jsp page("**filelist.jsp**") which contains all uploaded files by user. So I want to **Search** particular file using more filter options in jsp. I also tried using filtering and now it is partially completed. I have one ("**Search.jsp**") page where user searched data will be displayed. I also have "**Download**" column in my code so that user can download that file. **But the problem is that I am not able to download particular file from search.jsp page**.i am using netbeans8, tomcat 8.
This is my filelist.jsp Page

Deploying Common Lisp Web Applications : <p>I am wondering how one goes about deploying a Common Lisp web application written in, say, Hunchentoot, Wookie, Woo, or even Clack.</p>
<p>That is, suppose I write an app that contains some files, packages, etc. Typically when I am working locally, I simply run a command in REPL that starts the server and then visit it using <code>localhost:8000</code> or something like that.</p>
<p>However, I am a bit puzzled as to what the process is for deploying an app to a production server like AWS EC2. In what form should I deploy the Lisp code? Are there different options? What happens if the server needs to be restarted or is experiencing problems? </p>
