C++: Cannot copy line from an input file to an output file : <p>This is a home work question, so if you are not a fan of those I understand. Here is my code:</p>
<pre><code>#include <fstream>
#include <iostream>
#include <string>
using namespace std;
int main()
{
fstream myfile1("datafile1.txt"); //this just has a bunch of names in it
fstream myfile2("cmdfile1.txt"); //has commands like "add bobby bilbums"
ofstream outputFile("outfile1.txt"); //I want to take the "add bobby" command and copy the name into this new file.
string line;
if (myfile1.is_open() && myfile2.is_open()) //so I open both files
{
if (myfile2, line == "add"); //If myfile2 has an "add" in it
{
outputFile.is_open(); //open outputfile
outputFile << line << endl; //input the line with add in it till the end of that line.
}
}
cout << "\nPress Enter..."; // press enter and then everything closes out.
cin.ignore();
outputFile.close();
myfile2.close();
myfile1.close();
return 0;

<p>Problem is, though the outputFile is always empty. It never copies any lines from cmdfile1 into the output file. Does anyone know what I am missing here? </p>

Writing CSV Rows to a Dataframe : I am using the csv library to read specific rows from several files I have. The problem I am having is saving those rows into a dataframe. I am getting an indexing error that I can't solve.
The current version of the code finds the column names (which is on the third row) and then starts finding the data I need (which starts on the sixth row and continues until it hits a blank row). Finding the column names works fine, but when I try to append the data to it, I get the error:
"InvalidIndexError: Reindexing only valid with uniquely valued Index objects"
The code I currently have is as follows:
i=0
import csv
import pandas as pd
df = pd.DataFrame()
with open('C:/Users/sword/Anaconda3/envs/exceltest/RF_SubjP02_Free_STATIC_TR01.csv', 'r') as csvfile:
csvreader = csv.reader(csvfile, delimiter=',')
for row in csvreader:
if csvreader.line_num == 3: #this is for the column names
print(row)
df = pd.DataFrame(columns = row)
df.columns = row
if csvreader.line_num >= 6: #this is for the data
if row: #checks for blank row
if i<10: #just printing the top ten rows for debugging purposes, theres thousands I need
print(i)
i+=1
df.append(row) #this is where I get the indexing error
else: # breaks out of loop if
break
print(df) #for double checking if it worked

How to stop bokeh from opening a new tab in Jupyter Notebook? : <p>First of all, before this is tagged as duplicate, I have read the other solutions and unfortunately none of them worked for me.</p>
<p>My problem is that I want to display a bokeh plot in Juypter Notebook (and only in Jupyter Notebook), not in a new tab/window.</p>
<p>In the official documentation <a href="http://bokeh.pydata.org/en/latest/docs/user_guide/notebook.html#inline-plots" rel="noreferrer">here</a> I am told that I only need to change</p>
<pre><code>output_file
</code></pre>
<p>to </p>
<pre><code>output_notebook
</code></pre>
<p>Even though the plot <strong>is</strong> now displayed inline if I do that, bokeh won't stop also opening a new tab and needlessly displaying the plot there.</p>
<p>Since I'm gonna create lots of plots in my project, it'd be very nice to not always have to close this new tab and return to notebook, but just have it stop creating new tabs, just as it would work with e.g. matplotlib.</p>
<p>What confuses me is that if I load up the <a href="https://hub.mybinder.org/user/bokeh-bokeh-notebooks-obozp12q/notebooks/tutorial/02%20-%20Styling%20and%20Theming.ipynb" rel="noreferrer">official tutorial</a> and enter code there, for example</p>
<pre><code>import numpy as np
x = np.linspace(0, 10, 100)
y = np.exp(x)
p = figure()
p.line(x, y)
show(p)
</code></pre>
<p>there is no new tab opened. If I now run the same code locally on my machine's Juypter Notebook, it <strong>does</strong> open up a new tab.</p>
<p>I've been trying for a while now to fix this, any help would be very much appreciated.</p>
<p>Thanks in advance, Vincent</p>

<p>Where should I put all the connection initialisation code so that I can have access to it afterwards from a controller? Is this something I would use dependency injection for?</p>

What's the best/proper way to set up my database : <p>I have a database, image below, and I feel that there must be an efficient way to add separate books for each child. For example... there may be 50 clubbers in the database. Each clubber will be in their own book and to make it simple, each book has 10 sections a clubber must complete. I was thinking of making a table for each child with the 10 sections, but that would end up with over 50 tables in my database. I also thought of creating a table called book and just having that table contain the 10 sections, but the problem with that is each child may be in one of 8 different books. So one table called book wouldn't work either. </p>
<p>Does anyone have a good suggestion on how to set this up in the database? My ultimate goal is to have each child linked to one of the 8 books that is available. Then the database will track which section each child is in for their certain book. So... today clubber A could finish section 1 and 2 in book 1, but clubber B might only finish section 1 in book 2. I'm wanting to pull this information from the database to see where each clubber is in their books... but... I first need to set the database up correctly.</p>
<p>Should I create 8 separate tables for each of the books and have the table data be section 1... section 2...? Or should I create one table and list 8 books in it and then link that to another table that has the section info? Or is there an even better way?</p>

Python .append not working when found within a for, if else : <p>Working on a list creator to generate assignments for a sound crew.

MvcBuildViews true causes "'/temp' is not a valid IIS application" error : <p>After setting <code>MvcBuildViews</code> to <code>true</code> in my <code>.csproj</code> file in order to have the views compile during build, I get the following error:</p>
<blockquote>
<p>'/temp' is not a valid IIS application</p>
</blockquote>
<p>I presume that the '/temp' that this is referring to is the path where the views will be compiled. Here's the relevant section in the <code>.csproj</code> file:</p>
<pre><code><Target Name="MvcBuildViews" AfterTargets="AfterBuild" Condition="'$(MvcBuildViews)'=='true'">
<AspNetCompiler VirtualPath="temp" PhysicalPath="$(WebProjectOutputDir)" />
</Target>
</code></pre>
<p>I use full IIS to serve up this MVC 5 website on my local machine (haven't tried this on a remote server yet). Do I need to set something up in IIS to make <code>MvcBuildViews</code> work correctly?</p>

in python3: most efficient way to modify each element in multiple lists together? : Let's say I have 3 lists
```
a = [1.12, 2.23, 3.34]
b = [2.12, 3.23, 4.34]
c = [3.12, 4.23, 5.34]
```
my goal is to round the numbers down to 1 decimal. so I have this custom function:
```
import math
def round_down(n, decimals=0):
multiplier = 10 ** decimals
return math.floor(n * multiplier) / multiplier
```
May I ask what is the most efficient way of operating on each element in each object? In this easy example I could write a loop for each of the 3 objects, such as:
```
for i in np.range(len(a)):
a[i] = round_down(a[i], decimals=1)
```
However, in my work, I have many more lists of various lengths and I really don't want to code them one by one. Is there a way to iterate through a list of objects? or process them in parallel?
Thank you so much!

<p>But Bootstrap 4 modal doesn't:
<a href="https://jsfiddle.net/qLy7gk3f/3/" rel="noreferrer">https://jsfiddle.net/qLy7gk3f/3/</a></p>
<p>The code is identical:</p>
<pre><code>$scope.click = function() {
$uibModal.open({

</code></pre>
<p>How can I get AngularUI modals to work with Bootstrap 4?</p>

How to use requestReview (SKStoreReviewController) to show review popup in the current viewController after a random period of time : <p>I've read about this new feature available in iOS 10.3 and thought it will be more flexible and out of the box. But after I read the <a href="https://developer.apple.com/reference/storekit/skstorereviewcontroller?language=objc" rel="noreferrer">docs</a> I found out that you need to decide the time to show it and the viewController who calls it. Is there any way I can make it trigger after a random period of time in any viewController is showing at that moment? </p>

Configure different timeouts in gunicorn for different endpoints? : <p>Gunicorn allows configuring a timeout for requests, as demonstrated in their documentation below. This seems to be a global configuration for the entire application.</p>
<p>Is it possible to configure different timeouts for different endpoints? Perhaps overriding the default timeout on url endpoints that are known to take a long time?</p>
<p><a href="http://docs.gunicorn.org/en/stable/settings.html#timeout" rel="noreferrer">http://docs.gunicorn.org/en/stable/settings.html#timeout</a></p>
<blockquote>
<p>timeout</p>
<p>-t INT, --timeout INT</p>
<p>30</p>
<p>Workers silent for more than this many seconds are killed and restarted.</p>
<p>Generally set to thirty seconds. Only set this noticeably higher if
you’re sure of the repercussions for sync workers. For the non sync
workers it just means that the worker process is still communicating
and is not tied to the length of time required to handle a single
request.</p>

Sammy.js cache and scroll position when going back in history : <p>I don't know if anyone is still using Sammy.js, but I found it perfectly suits my needs for a lightweight routing and templating library. If anyone has other ideas, please let me know.</p>
<p>My problem is that when I have a long page and I scroll down, click on a link on this page and go back, the whole page is reloaded (in Sammy, the GET route is called) and it jumps to the top of the page.</p>
<p>My question is: Is there a way to have Sammy cache the page and maintain the scroll position when going back in the history?</p>

I want to write a function that prints a sum : I just started python a few weeks ago and I want to write a function that opens a file, counts and adds up the characters in each line and prints that those equal the total number of characters in the file.
For example, given a file test1.txt:
lineLengths('test1.txt')
The output should be:
15+20+23+24+0=82 (+0 optional)
This is what I have so far:
def lineLengths(filename):
f=open(filename)
lines=f.readlines()
f.close()
answer=[]
for aline in lines:
count=len(aline)
It does what I want it to do, but I don't know how include all of the numbers added together when I have the function print.

Use a different user.email and user.name for Git config based upon remote clone URL : <p>I configure my global <code>~/.gitconfig</code> properties <code>user.name</code> and <code>user.email</code> like this:</p>
<p></p>
<pre><code>git config --global user.email "mkobit@example.com"
git config --global user.name "mkobit"
</code></pre>
<p>This is the default configuration I want for working on personal projects, open source stuff, etc.</p>
<p>When I am working on a project from a specific domain, a corporate domain for example, I am configuring it for each repository when I clone it so that it uses a different <code>user.name</code>/<code>user.email</code>:</p>
<pre><code>git clone ssh://git@git.mycorp.com:1234/groupA/projectA.git
cd projectA
git config user.email "mkobit@mycorp.com"
git config user.name "m.kobit"
</code></pre>
<p>One decent option would be to setup an alias for cloning these kinds of repositories:</p>
<pre><code>git config --global alias.clonecorp 'clone \
-c user.name="m.kobit" -c user.email="mkobit@mycorp.com"'
git clonecorp ssh://git@git.mycorp.com:1234/groupA/projectA.git
</code></pre>
<p>Both of these can be error prone because they both depend on me being smart and following the right steps. Evidence shows that this is near-guaranteed for me to screw-up sometime.</p>
<p>Is there a way to configure Git such that repositories from a certain domain (the <code>mycorp.com</code> in this example) will be configured a certain way? </p>

Event Handlers in React Stateless Components : <p>Trying to figure out an optimal way to create event handlers in React stateless components. I could do something like this:</p>

return (
<button onClick={myHandler}>Click Me</button>
);

<p>The drawback here being that every time this component is rendered, a new "myHandler" function is created. Is there a better way to create event handlers in stateless components that can still access the component properties?</p>

Updating Visual Studio 2015 extensions end up disabled : <p>I have a machine with seems to repeat the following pattern with VS2015 (including all patches).</p>
<ol>
<li>Install an extension and it's fine, works perfectly.</li>
<li>The developer of the extension releases a new update.</li>
<li>Update extension, which means VS2015 needs to be restarted.</li>
<li>Restart VS2015, look in the extensions and notice that the (updated) extension is now disabled.</li>
</ol>
<p>I've tried clearing the MEF cache, but that doesn't seem to help. The only way I've found to resolve this is to </p>
<ol>
<li>Delete the extension</li>
<li>Restart VS2015</li>
<li>Notice the extension is still there as disabled</li>
<li>Delete it again</li>
<li>Restart VS2015 (it's now removed)</li>
<li>Install the extension from fresh from the Extension manager.</li>
</ol>
<p>I have another machine which doesn't experience this, and also the activity.xml file doesn't get updated unless there is a loading issue (where you get the error pop-up).</p>
<p>The first time I noticed this was when I installed Mads Kristensen's Web extensions pack (which included all of his components) and caused all the pre-installed components to be disabled, so I uninstalled that and deleted all the components that were bundled under that, as it looked like it didn't detect the component were already there and created a duplicate behind the scenes, but now it seems this is happening for all 3rd party components.</p>
<p>Has anyone got any ideas what I can try to resolve this and possibly what could be causing this?</p>
<p>I'm hoping there is a file somewhere in the VS folder that is logging the issue.</p>

Clear React Native TextInput : <p>Working through the Redux AddTodo example in React Native. The first AddTodo example below uses state to store the TextInput value and works fine.</p>

update(e){
if(this.state.todoText.trim()) this.props.dispatch(addTodo(this.state.todoText));

}
render(){
return(
<TextInput

onSubmitEditing = { (e)=> { this.update(e); } }
onChangeText = { (text) => {this.setState({todoText: text}) } } />
);
}
}
</code></pre>
<p>However following a few of the Redux examples, the following code is much shorter and also works except that the <code>TextInput</code> <code>value</code> is not cleared after submitting</p>

If we want use S3 to host Python packages, how can we tell pip where to find the newest version? : <p>we are trying to come up with a solution to have AWS S3 to host and distribute our Python packages. </p>
<p>Basically what we want to do is using "python3 setup.py bdist_wheel" to create a wheel. Upload it to S3. Then any server or any machine can do "pip install $<a href="http://path/on/s3" rel="noreferrer">http://path/on/s3</a>". (including a virtualenv in AWS lambda)
(We've looked into Pypicloud and thought it's an overkill.)</p>
<p>Creating package and installing from S3 work fine. There is only one issue here: we will release new code and give them different versions. If we host our code on Pypi, you can upgrade some packages to their newest version by calling "pip install package --upgrade". </p>
<p>But if you host your packages on S3, how do you let pip know there's a newer version exists? How do you roll back to an older version by simply giving pip the version number? Is there a way to let pip know where to look for different version of wheels on S3?</p>

valarray with arithmetic operations return type : <p>When I write a simple arithmetic expression with <code>valarray</code> and assign the result to <code>auto</code> I get a segfault when I try to access the result on gcc.</p>

std::cout << "c: " << c << "\n";
valarray<double> x = ( a + b ) / 2;
std::cout << "x: " << x << "\n";
// this still works:
auto y = ( a + b ) / 2;
// The following will result in a segfault:
std::cout << "y:" << y << "\n";
}
</code></pre>
<p>The <a href="http://www.cplusplus.com/reference/valarray/valarray/operators/" rel="noreferrer">reference</a> says that the implementation may choose that the return type of the arithmetic operation overloads may not be a <code>valarray</code>-value but something that "behaves like it":</p>
<blockquote>
<p>The operators returning a valarray by value are allowed to return an object of a different type instead. Such a type is required to be implicitly convertible to valarray and be supported as argument for all functions taking valarray& arguments. This allows copy-on-write implementations.</p>
</blockquote>
<p>Well, my <code>operator<<</code> should call for that "implicit conversion", shouldnt it?</p>
<p>So why do I get a segfault?</p>

Replace vector of vector with flat memory structure : <p>I have the following type:</p>
<pre><code>std::vector<std::vector<int>> indicies
</code></pre>
<p>where the size of the inner vector is always 2. The problem is, that vectors are non-contiguous in memory. I would like to replace the inner vector with something contiguous so that I can cast the flattened array:</p>
<pre><code>int *array_a = (int *) &(a[0][0])
</code></pre>
<p>It would be nice if the new type has the [] operator, so that I don't have to change the whole code. (I could also implement it myself if necessary). My ideas are either:</p>
<pre><code>std::vector<std::array<int, 2>>
</code></pre>
<p>or </p>
<pre><code>std::vector<std::pair<int, int>>
</code></pre>
<p>How do these look in memory? I wrote a small test:</p>
<pre><code>#include <iostream>
#include <array>
#include <vector>
int main(int argc, char *argv[])
{
using namespace std;
vector<array<int, 2>> a(100);
cout << sizeof(array<int, 2>) << endl;
for(auto i = 0; i < 10; i++){
for(auto j = 0; j < 2; j++){
cout << "a[" << i << "][" << j << "] "
<<&(a[i][j]) << endl;
}
}
return 0;
}
</code></pre>
<p>which results in:</p>
<pre><code>8
a[0][0] 0x1b72c20
a[0][1] 0x1b72c24
a[1][0] 0x1b72c28
a[1][1] 0x1b72c2c

import 'rxjs/add/operator/map';
import 'rxjs/add/operator/catch';
import 'rxjs/add/observable/throw';

"Note: Recompile with -Xlint:unchecked for details." after compile and when I want to run it message "Exception in thread "main" java.lang.NullPointerException" appears.</p>
<p>the code is (All is in main method) : </p>
<pre><code>int v = 8;
ArrayList<Integer>[] adj = new ArrayList[11];
adj[0].add(21);
</code></pre>
<p>and the error belongs to the last line.
