Trying to understand a Bash script given to me, specifically the while loop : <p>I am using a script made by one of my former colleagues, he told me I'll need some working with it. I am wondering what this while loop does:</p>
<pre><code># This is the loop that does the simulation
lastsim=0
nextsim=`/usr/bin/expr $lastsim + 1`
while [ $nextsim -le $upperlimit ]
do
cp -i Dynamics_${lastsim}_500ps/*.prmtop ./$paramInput.prmtop
</code></pre>
<p>specifically I'm confused by thie -le syntax
This is only part of the script I can upload the rest if necessary.</p>

Android: Error while installing APKs : <p>I'm slowly trying to do some simple tasks in <code>Android Studio</code>. The following app is installed on emulator without any errors. But when I tried to install it on a real device Redmi 3S this error occured:</p>
<pre><code>Unknown failure (Failure - not installed for 0)
Error while Installing APKs
</code></pre>
<p>I went through similar questions around here but in these cases the error was caused by not enabled debugging, or not accepitng the app instalation. However, I allowed debugging and I also tried to install <strong>some other app</strong> in Studio and it <strong>worked fine</strong>.</p>
<p>So the question probably is, what's wrong with the code.</p>

<p>MainActivity.java</p>

Convert incoming bytestream into integers and export to excel Arduino/C : I am very new to programming and am working on an Arduino project to measure wavelengths of light. I am using the Spectruino 3 (http://myspectral.com/spectruino-installation.html) and am trying to read in the bytes that it records into an array, convert the array into an integer array and then export that data to excel. Currently I have this:
const int numBytes = 501;
int bytestream[numBytes];
void setup(){
Serial.begin(115200);
}
void loop() {
for(int i=0; i<numBytes; i++){
bytestream[i]=Serial.read();
}
}
My spectrometer currently doesn't work, but this seems to compile. I was just wondering how to convert this bytestream array into an integer array and then export it into excel. Thanks!

CouchDb Which is the Best Performing approach to find data using Views or N1sql : i am building an php application using couchdb (mostly), but still not completely clear on the best approach for fetching contents, there are 2 different ways to get data (if i am correct)
1. Using View functions
2. Querying Data with N1QL
That mean i can get same content using these 2 options..
For my developments purpose (n1sql) second option is more suitable. But still i am willing to rewrite my models to use more view function , if that approach works well (in terms good performance, less RAM and CPU usage, less maintenance costs, etc. )
Please share your thoughts about this
Thanks in advance

Python how to use the __str__ code for the __repr__? : <p>I've stated programming in Phyton just few days ago, so I'm sorry if the question is quite easy.</p>
<p>I've written this code:</p>
<pre><code>>>> class Polynomial:
def __init__(self, coeff):
self.coeff=coeff
def __repr_(self):
return str(self)
def __str__(self):
s=''
flag=0;
for i in reversed(range(len(self.coeff))):
if(i==0):
s+= '+ %g ' % (self.coeff[i])
elif (flag==0):
flag=1
s+= '%g z**%d' % (self.coeff[i],i)
else:
s+= '+ %g z**%d ' % (self.coeff[i],i)
return s
</code></pre>
<p>but <code>__repr__</code> is not working:</p>
<pre><code>>>> p= Polynomial([1,2,3])
>>> p
<__main__.Polynomial instance at 0x7fd3580ad518>
>>> print p
3 z**2+ 2 z**1 + 1
</code></pre>
<p>How can i use the code wrritten in <code>def __str__(self):</code> without re-writining it? I couldn't find the answer anywhere else.
thanks.</p>

NameError: name 'user_id' is not defined. For no apparent reason : <p><strong>Error description</strong></p>
<p>I would fire up the server program, and fire a request (GET) at the path <code>/test_connection</code> which is the path used by the client to test the server IP address btw. The server would then respond by printing out the traceback below in the console, the one line in particular that I can't get my head around is <code>NameError: name 'user_id' is not defined</code> as the variable is not even included in the response function for the path <code>/test_connection</code> (<code>connection_test()</code>). I know the error is on the server side as it will print out 'INTERNAL SERVER ERROR: 500' on the client code, so I didn't feel the necessity to include the client code.</p>

sqlalchemy postgresql enum does not create type on db migrate : <p>I develop a web-app using Flask under Python3. I have a problem with postgresql enum type on db migrate/upgrade.</p>
<p>I added a column "status" to model:</p>
<pre><code>class Banner(db.Model):
...
status = db.Column(db.Enum('active', 'inactive', 'archive', name='banner_status'))
...
</code></pre>
<p>Generated migration by <code>python manage.py db migrate</code> is:</p>
<pre><code>from alembic import op
import sqlalchemy as sa
def upgrade():
op.add_column('banner', sa.Column('status', sa.Enum('active', 'inactive', 'archive', name='banner_status'), nullable=True))
def downgrade():
op.drop_column('banner', 'status')
</code></pre>
<p>And when I do <code>python manage.py db upgrade</code> I get an error:</p>
<pre><code>...
sqlalchemy.exc.ProgrammingError: (psycopg2.ProgrammingError) type "banner_status" does not exist
LINE 1: ALTER TABLE banner ADD COLUMN status banner_status
[SQL: 'ALTER TABLE banner ADD COLUMN status banner_status']
</code></pre>
<p><strong>Why migration does not create a type "banner_status"?</strong></p>

File extension naming: .p vs .pkl vs .pickle : <p>When reading and writing pickle files, I've noticed that some snippets use <code>.p</code> others <code>.pkl</code> and some the full <code>.pickle</code>. Is there one most pythonic way of doing this?</p>
<p>My current view is that there is no one right answer, and that any of these will suffice. In fact, writing a filename of <code>awesome.pkl</code> or <code>awesome.sauce</code> won't make a difference when running <code>pickle.load(open(filename, "rb"))</code>. This is to say, the file extension is just a convention which doesn't actually affect the underlying data. Is that right?</p>
<p>Bonus: What if I saved a PNG image as <code>myimage.jpg</code>? What havoc would that create?</p>

Programming Homework: Robot Genetic Algorithm : <p>This program is built to run 10000 generations of 200 robots, allowing evolution to shape the digits in the robot's "DNA". The problem I'm having is that, even though there is nothing but numbers going into the 'robotGenes' array, the resulting DNA that prints is a random collection of letters, numbers and symbols. I have absolutly no idea why. I have tried switching up where I declare and assign my variables, unfortunatly its all been in vane. Plz halp. </p>

unable to run 'aws' from cygwin : <p>I'm using <code>cygwin</code> installed on <code>Windows 10</code> and trying to access <code>awscli</code> from it.</p>
<p>I used <code>pip install awscli</code> to install <code>awscli</code>. This installed <code>awscli</code>. I then tried to run only <code>aws</code> to see if it is installed and I get the following error:</p>
<pre><code>-bash: /cygdrive/c/Program Files/Anaconda2/Scripts/aws: C:\Program: bad interpreter: No such file or directory

Safely assign value to nested hash using Hash#dig or Lonely operator(&.) : <pre><code>h = {
data: {
user: {
value: "John Doe"
}
}
}
</code></pre>
<p>To assign value to the nested hash, we can use</p>
<pre><code>h[:data][:user][:value] = "Bob"
</code></pre>
<p>However if any part in the middle is missing, it will cause error.</p>
<p>Something like </p>
<pre><code>h.dig(:data, :user, :value) = "Bob"
</code></pre>
<p>won't work, since there's no <code>Hash#dig=</code> available yet.</p>
<p>To safely assign value, we can do</p>
<pre><code>h.dig(:data, :user)&.[]=(:value, "Bob") # or equivalently
h.dig(:data, :user)&.store(:value, "Bob")
</code></pre>
<p>But is there better way to do that? </p>

NullPointerException when pressing JOptionPane Cancel button : <p>I am writing a program to choose between different shape and then input the values (e.g. radius) to calculate the volume of the shape using JOptionPane, I did some input validation, but the problem is whenever I press the cancel button of the JOptionPane.showInputDialog, the program crash with the following error,
where is the problem comes from? And how can I solve it? Thanks!</p>
<pre><code>while(choice.equalsIgnoreCase("y")) {
.......
if (n== JOptionPane.YES_OPTION)
{
while (notDone) {
try {
radiusStr = JOptionPane.showInputDialog("Please enter the radius of the sphere");
radius = Double.parseDouble(radiusStr);
notDone = false;
}
catch (NumberFormatException e ){
JOptionPane.showMessageDialog(null, "Input error! Please enter a number.");
continue;

volume = new CircularVolume(radius);

Leaflet: Map container not found : <p>I have the below react class which fetches the geolocation through the browser.</p>
<p>I am mapping a leaflet map. I want to geolocation to be an input to the setView, for such that the map "zooms" into the region of the client browser location. </p>
<p>Here's the react class: </p>
<pre><code> import React from 'react';
import L from 'leaflet';
import countries from './countries.js';
var Worldmap = React.createClass({
render: function() {
let geolocation = [];
navigator.geolocation.getCurrentPosition(function(position) {
let lat = position.coords.latitude;
let lon = position.coords.longitude;
geolocation.push(lat, lon);
locationCode()
});
function locationCode() {
if(geolocation.length <= 0)
geolocation.push(0, 0);
}
let map = L.map('leafletmap').setView(geolocation, 3);
L.geoJSON(countries, {
style: function(feature) {
return {
fillColor: "#FFBB78",
fillOpacity: 0.6,
stroke: true,
color: "black",
weight: 2
};
}
}).bindPopup(function(layer) {
return layer.feature.properties.name;
}).addTo(map);
return (
<div id="leafletmap" style={{width: "100%", height: "800px" }}/>
)
}
});
export default Worldmap
</code></pre>
<p>It's called in a main file where the HTML is rendered as <code><WorldMap /></code>.</p>
<p>I get the error <code>Uncaught Error: Map container not found.</code> when loading the page. Looking around, usually it would be because the map is trying to be displayed in a div before being provided values((gelocation, 3) in this case). However, it shouldn't display it before being returned from the render function below. </p>
<p>What could the issue be?</p>
<p>Printing out the <code>geolocation</code> in the console correctly fetches the coordinates, so that doesn't seem to be the issue. </p>

Populating Dropdown in ASP.net Core : <p>Does anyone know how to deal with Dropdowns in Asp.net core. I think I made myself very complicated to understand the new Asp.net core concept. (I am new to Asp.net Core).</p>
<p>I have models called <code>Driver</code>, <code>Vehicle</code>. Basically one can create bunch of vehicles in the master then attach it to the Driver. So that the driver will be associated with a vehicle.</p>
<p>My problem is that I am also using viewmodel in some area to combine two different models.(understood little from default template)</p>
<p>My problem is I have no idea what is the next step since ASP.net Core is very latest, there are not a lot of tutorials and Q/As available.</p>

Removing sandbox accounts from tvOS 13 : <p>I have been developing a tvOS app that uses in-app purchasing. As part of the development process, the app must be tested using iTunes sandbox user accounts. When beginning the in-app purchase using a local build, the user is prompted for the account credentials to one of these sandbox accounts.</p>
<p>The problem arises with tvOS 13, which does not appear to let you log out from or remove a sandbox account from the device once entered. While this might be okay for purchasing a single time, going through the purchase process again requires a new sandbox account, since otherwise, the purchase would be treated as a renewal rather than a new purchase.</p>
<p>Has anyone figured out a way to log out of a sandbox account with an Apple TV running tvOS 13? The only workaround I have found is to perform a reset on the device and go through the setup process again costing a great deal of time.</p>

Vuejs doesn't render components inside HTML table elements : <p>I want to render a custom component that displays a row inside a table.</p>
<p>I have the following code:</p>
<pre><code>// js file
Vue.component('message-row', {
data: function () {
return {
msg: 'Hello'
}
},
template: '<tr><td>{{ msg }}</td></tr>'
});
new Vue({
el: '#app'
});
// html file
<div id="app">
<table><message-row></message-row></table>
</div>

<p>The problem is that the row ends up rendered outside the table! Like this:</p>
<pre><code><div id="app">
<tr><td>Hello</td></tr>
<table></table>
</div>

How to find which Yocto Project recipe populates a particular file on an image root filesystem : <p>I work with the Yocto Project quite a bit and a common challenge is determining why (or from what recipe) a file has been included on the rootfs. This is something that can hopefully be derived from the build system's environment, log & meta data. Ideally, a set of commands would allow linking a file back to a source (ie. recipe).</p>
<p>My usual strategy is to perform searches on the meta data (e.g. <code>grep -R filename ../layers/*</code>) and searches on the internet of said filenames to find clues of possible responsible recipes. However, this is not always very effective. In many cases, filenames are not explicitly stated within a recipe. Additionally, there are many cases where a filename is provided by multiple recipes which leads to additional work to find which recipe ultimately supplied it. There are of course many other clues available to find the answer. Regardless, this investigation is often quite laborious when it seems the build system should have enough information to make resolving the answer simple.</p>

C++ dereferencing for std::priority_queue::top : <p>Documentation states <code>std::priority_queue::top</code> returns a constant reference to the top element in the priority_queue, but when printing the top element, the unary dereference operator is not used. </p>
<pre><code>// priority_queue::top
#include <iostream> // std::cout
#include <queue> // std::priority_queue
int main ()
{
std::priority_queue<int> mypq;
mypq.push(10);
mypq.push(20);
mypq.push(15);
std::cout << "mypq.top() is now " << mypq.top() << '\n';
return 0;
}
</code></pre>
<p>Is <code>top()</code> being implicitly dereferenced or is the returned value a copy?</p>

python generators garbage collection : <p>I think my question is related to <a href="https://stackoverflow.com/questions/15490127/will-a-python-generator-be-garbage-collected-if-it-will-not-be-used-any-more-but">this</a>, but not exactly similar. Consider this code:</p>
<pre><code>def countdown(n):
try:
while n > 0:
yield n
n -= 1
finally:
print('In the finally block')
def main():
for n in countdown(10):
if n == 5:
break
print('Counting... ', n)
print('Finished counting')
main()
</code></pre>
<p>The output of this code is:</p>
<pre><code>Counting... 10
Counting... 9
Counting... 8
Counting... 7
Counting... 6
In the finally block
Finished counting
</code></pre>
<p>Is it guaranteed that the line "In the finally block" is going to be printed before "Finished counting"? Or is this because of cPython implementation detail that an object will be garbage collected when the reference count reaches 0.</p>
<p>Also I am curious on how <code>finally</code> block of the <code>countdown</code> generator is executed? e.g. if I change the code of <code>main</code> to</p>
<pre><code>def main():
c = countdown(10)
for n in c:
if n == 5:
break
print('Counting... ', n)
print('Finished counting')
</code></pre>
<p>then I do see <code>Finished counting</code> printed before <code>In the finally block</code>. How does the garbage collector directly go to the <code>finally</code> block? I think I have always taken <code>try/except/finally</code> on its face value, but thinking in the context of generators is making me think twice about it. </p>

Why is this Java code returning a memory address? : <p>This code is returning a memory address of an array being returned by the rgb2hsv function. I am not sure as to why this is, or if it is even a memory address that it is returning as I am familiar with memory addresses looking something along the lines of "0x038987086" but the code is returning something that looks more like this : "[F@12bb4df8", I am not sure as to why this is, if you could answer why and what it exactly what it is returning that would be extremely beneficial.
Here is the code:</p>
<pre><code> public class HelloWorld{
public static float max(float[] nums) {
if (nums[0] > nums [1] && nums[0] > nums[2]) {
return nums[0];
}
if (nums[1] > nums [0] && nums[1] > nums[2]) {
return nums[1];
}
if (nums[2] > nums[0] && nums[2] > nums[1]) {
return nums[2];
}
return 0;
}
public static float min(float[] nums) {
if (nums[0] < nums [1] && nums[0] < nums[2]) {
return nums[0];
}
if (nums[1] < nums [0] && nums[1] < nums[2]) {
return nums[1];
}
if (nums[2] < nums[0] && nums[2] < nums[1]) {
return nums[2];
}
return 0;
}
public static float[] rgb2hsv(float r,float g, float b) {
float h;
//Initializes h
h=0;
float s;
float v;
// Floats added to avoid operator precedence
float x;
float a;
float hue;
//Divides by 255
r=r/255;
g=g/255;
b=b/255;
float[] rgbArray = {r,g,b};
float mx= max(rgbArray);
float mn= min(rgbArray);
float df= mx-mn;
if (mx == mn) {
h=0;
}
if (mx==r) {
x=g-b;
a=x/df+360;
hue=a % 360;
h=hue;
}
if (mx==g) {
x=b-r;
a=x/df+120;
hue=a % 360;
h=hue;
}
if (mx==b) {
x=r-g;
a=x/df+240;
hue=a % 360;
h=hue;
}
if(mx==0) {
s=0;
}
else {
s=df/mx;
}
v=mx;
float[] hsvArray = {h,s,v};
return hsvArray;
}
public static void main(String []args){
float[] x=rgb2hsv(255, 255, 0);
System.out.println(x);
}
</code></pre>
<p>}</p>
<p>This should of outputted something along the lines of 3 distinct numbers telling me hue, value, and saturation. Instead it returns something similar to "[F@12bb4df8"</p>

HTML & CSS formatting bug when printing web page : I am attempting to print a web page via Ctrl-P or right-click print so I can save it as a PDF. Up until several minutes ago, this was working flawlessly. I have made some minor sizing edits to the grid I am working with on the page and now when I attempt to print, the web page is displaying some formatting glitches on the preview screen.
The problem is shown below. There are various borders missing from the grid and this is carrying over to the PDF when fully saved.

Airflow - how to make EmailOperator html_content dynamic? : <p>I'm looking for a method that will allow the content of the emails sent by a given EmailOperator task to be set dynamically. Ideally I would like to make the email contents dependent on the results of an xcom call, preferably through the html_content argument.</p>
<pre><code>alert = EmailOperator(
task_id=alertTaskID,
to='please@dontreply.com',
subject='Airflow processing report',
html_content='raw content #2',
dag=dag
)
</code></pre>
<p>I notice that the Airflow docs say that xcom calls can be embedded in templates. Perhaps there is a way to formulate an xcom pull using a template on a specified task ID then pass the result in as html_content? Thanks</p>

How to fill in [x]% of a 2d array with the values of another array : <p>I have 2 two-dimensional arrays, one is filled and one is to be filled, both of the same size (n x m). I need to fill in [some random]% of my second array with the exact same values as my first array.
So let's say</p>
<pre><code>int[][] arr1 = new int[][] {{0, 1, 0, 1},
{1, 0, 1, 0},
{0, 0, 1, 1},
{1, 1, 0, 0}};
</code></pre>
<p>I want arr2 to be filled with 25% of arr1's values in the same spot with the other spots just remaining null..</p>
<pre><code>int[][] arr2 = new int[4][4];
// where arr2 = something like {{0,1,0,1},
// { , , , },
// { , , , },
// { , , , }}
</code></pre>
<p>Eventually, the program will call on the user to fill in the missing values, which I can do, just for some reason this part seems to not want to work for me.
This is for a school assignment and the teacher isn't being very helpful with answering questions.</p>
<p>Here's my code:
noting that (variable names are in French..)</p>
<ol>
<li>nbCases = total number of elements in the 2d array</li>
<li>nbARemplir = number of elements in the 2nd array to have values assigned to them (based on nbCases * nbPourc where nbPourc is the percentage of the 2nd array to be assigned values)</li>
<li>grille[][] = original array</li>
<li><p>gui = second "array" (it's actually a 2d array of JButtons that the teacher wrote..syntax to add a value : gui.setValeur(i, j, value) )</p>
<pre><code>int nbCases = grille.length * grille[0].length;
int nbARemplir = (int)(nbCases * nbPourc);
do{
for(int i = 0; i < grille.length; i++) {
for(int j = 0; j < grille[i].length; j++) {
if(rand.nextInt(2) == 1 && nbARemplir > 0) {
gui.setValeur(i, j, "" + grille[i][j]);
nbARemplir--;
}
}
}
} while(nbARemplir > 0);
</code></pre></li>

Post files from ASP.NET Core web api to another ASP.NET Core web api : <p>We are building a web application that consist of an Angular2 frontend, a ASP.NET Core web api public backend, and a ASP.NET Core web api private backend.</p>
<p>Uploading files from Angular2 to the public backend works. But we would prefer to post them forward to the private backend.</p>
<p>Current working code</p>
<pre><code>[HttpPost]
public StatusCodeResult Post(IFormFile file)
{
...
}
</code></pre>
<p>From there I can save the file to disk using file.CopyTo(fileStream);</p>
<p>However, I want to re-send that file, or those files, or, ideally, the whole request to my second web api core.</p>
<p>I am not sure how to achieve this with the HttpClient class of asp.net core.</p>
<p>I've tried all kinds of things such as</p>
<pre><code>StreamContent ss = new StreamContent(HttpContext.Request.Body);
var result = client.PostAsync("api/Values", ss).Result;
</code></pre>
<p>But my second backend gets an empty IFormFile.</p>
<p>I have a feeling it is possible to send the file(s) as a stream and reconstruct them on the other side, but can't get it to work.</p>
<p>The solution must use two web api core.</p>
