Print list without brackets or commas in python : <p>I'm working on a simple compression algorithm that compresses binary files. I am scanning the file and filling a list with the character & the number of times that character appears after it. The list however is formatted in a way that is making the compressed result larger due to all the brackets & commas and I need rid of these. I have tried several methods of removing them but nothing is working.
Here is the encode algorithm:</p>
<pre><code>def encode(inputString):
characterCount = 1
previousCharacter = ''
List = []
for character in inputString:
if character != previousCharacter:
if previousCharacter:
listEntry = (previousCharacter, characterCount)
List.append(listEntry)
#print lst
characterCount = 1
previousCharacter = character
else:
characterCount += 1
else:
try:
listEntry = (character, characterCount)
List.append(listEntry)
return (List, 0)
except Exception as e:
print("Exception encountered {e}".format(e=e))
return (e, 1)`
</code></pre>
<p>And here is where I print the list. The hashed comments are the methods I have already tried with no luck.</p>
<pre><code>value = encode(binaryfile)
if value[1] == 0:
print(value[0])
#flattened = [val for sublist in value for val in sublist]
#print(flattened)
#values = value[0]
#print(*value[0], sep='')
#print (''.join(map(str, value)))
#print(int("".join(str(x) for x in value[0])))
</code></pre>
<p>And here is the output.</p>
<pre><code>[('1', 2), ('0', 1), ('1', 1), ('0', 4), ('1', 2), ('0', 2), ('1', 4), ('0', 3), ('1', 1), ('0', 3), ('1', 4), ('0', 5), ('1', 1), ('0', 1), ('1', 1), ('0', 4), ('1', 2), ('0', 1), ('1', 2), ('0', 3), ('1', 1), ('0', 3), ('1', 2), ('0', 1), ('1', 1), ('0', 1), ('1', 3), ('0', 4), ('1', 1), ('0', 130), ('1', 5), ('0', 15), ('1', 2), ('0', 8), ('1', 7), ('0', 1), ('1', 8), ('0', 4), ('1', 1), ('0', 2), ('1', 1), ('0', 13), ('1', 2), ('0', 96), ('1', 1), ('0', 26), ('1', 3), ('0', 70), ('1', 1), ('0', 22), ('1', 3), ('0', 1), ('1', 1), ('0', 32), ('1', 1), ('0', 24), ('1', 7), ('0', 1), ('1', 24), ('0', 34), ('1', 2), ('0', 1), ('1', 3), ('0', 24), ('1', 3459), ('0', 1), ('1', 2), ('0', 2), ('1', 1), ('0', 1), ('1', 1), ('0', 2), ('1', 1), ('0', 1), ('1', 3), ('0', 5), ('1', 1), ('0', 10), ('1', 1), ('0', 2), ('1', 3), ('0', 1), ('1', 2), ('0', 9), ('1', 1), ('0', 2), ('1', 1), ('0', 5), ('1', 1), ('0', 18), ('1', 4), ('0', 7), ('1', 1), ('0', 2), ('1', 1), ('0', 1), ('1', 1),

serial in postgres is being increased even though I added on conflict do nothing : <p>I'm using Postgres 9.5 and seeing some wired things here.</p>
<p>I've a cron job running ever 5 mins firing a sql statement that is adding a list of records if not existing.</p>
<pre><code>INSERT INTO
sometable (customer, balance)
VALUES
(:customer, :balance)
ON CONFLICT (customer) DO NOTHING
</code></pre>
<p>sometable.customer is a primary key (text)</p>
<p><strong><em>sometable structure is:</em></strong><br>
id: serial<br>
customer: text<br>
balance: bigint </p>
<p>Now it seems like everytime this job runs, the id field is silently incremented +1. So next time, I really add a field, it is thousands of numbers above my last value. I thought this query checks for conflicts and if so, do nothing but currently it seems like it tries to insert the record, increased the id and then stops.</p>
<p>Any suggestions?</p>

Why does JSON.parse() add numbers in front of elements? : <p>I have a string where I build my build my "json-like" format, like</p>

{"foor":"bar","foo":"bar","foo":["bar,bar"]},
{"foor":"bar","foo":"bar","foo":["bar,bar"]}

<p>But after calling <code>JSON.parse</code> like <code>_afterFormat = JSON.parse(_toBeFormated)</code>, my structure looks like the following:</p>
<pre><code>_afterFormat =
0:{"foor":"bar","foo":"bar","foo":["bar,bar"]},
1:{"foor":"bar","foo":"bar","foo":["bar,bar"]},
2:{"foor":"bar","foo":"bar","foo":["bar,bar"]}
</code></pre>
<p>If I try to change to JSON Format at the beginning, like leaving out [ ], if failes to parse, also it looks like valid <code>JSON</code> to me. What am I missing, or why does it add the numbers at the beginning?</p>

SimpleDateFormat and not allowing it to go above 12 hours : <p>So I have this method that I wanted to expand on to have the user input a valid 12 hour time. And I have it to this which works okay. But I want it so that if the hour is over 12 hours or the minutes is over 59 then it will prompt to do it again. But right now it will just convert the time by adding it.
Also is there a more efficient way to write this? (Like without having the
<strong>Date newTime = sdf.parse(startTime);</strong> And have it so that the user can just input a string and have it check if it's in the correct format? </p>
<pre><code>public static void userInput(){
Scanner in = new Scanner(System.in);
SimpleDateFormat sdf = new SimpleDateFormat("hh:mm aa");
String startTime;
System.out.print("What is the start time?: ");
boolean success = false;
while (success != true){

Date newTime = sdf.parse(startTime);

System.out.println(startTime);

I am trying to design a function diagonal_check(board, row, col) where board is N*N matrix of arrays where '1' represents presence of queen and '0' represents absence.
I will pass array and position of queen (row,col) to the function. My function must return false if any other queen is present on its diagonal or else return true.
If anyone could help me with algorithm for diagonal_check function. Not looking for any specific language code.

C++ Trying to delete used line from txt file : <p>I'm trying to delete used lines from a txt file (questions.txt) and put them into another file (usedQuestions.txt), but right now the code just deletes questions.txt, doesn't put anything in temp.txt or renames it; and doesn't put anything in usedQuestions.txt</p>
<p>This is my code:</p>
<pre><code>#include <iostream>
#include <string>
#include <fstream>
using namespace std;
int main () {
// Loop infinitely
for (int i = 1; i > 0; i++) {
// Files
ifstream txtFile("questions.txt");
ofstream usedQuestions("usedQuestions.txt");
ofstream tempFile("temp.txt");
// Strings, ints etc.
string question;
string temp;
unsigned int lineNum = 1;
int requestedLineNum;
// User requests line
cin >> requestedLineNum;
cout << "You have requested question number: " << requestedLineNum << endl;
// Go through lines until the correct line is found
while (getline(txtFile, question))
{
//If the line number is correct, output question
if (lineNum == requestedLineNum)
{
cout << "Your question is: " << question << endl;
// Write to temporary file, doesn't work?
while (getline(txtFile, temp)) {
tempFile << temp;
}
// Write to file with used questions
usedQuestions << question;
}
// Set up for while loop to go through lines

// Close and remove questions.txt, rename temp.txt to questions.txt

Django-Rest-Framework. Updating nested object : <p>I'm having a problem of updating a nested object.</p>
<p>So I have a model which structure is similar to this one:</p>
<pre><code>class Invoice(models.Model):
nr = models.CharField(max_length=100)
title = models.CharField(max_length=100)
class InvoiceItem(models.Model):
name = models.CharField(max_length=100)
price = models.FloatField()
invoice = models.ForeignKey(Invoice, related_name='items')
</code></pre>
<p>I need to create child objects from parent, and what I mean by that, is to create <code>InvoiceItems</code> directly when creating an <code>Invoice</code> object.
For this purpose, I've wrote the following serializers:</p>
<pre><code>class InvoiceItemSerializer(serializers.ModelSerializer):
invoice = serializers.PrimaryKeyRelatedField(queryset=Invoice.objects.all(), required=False)
class Meta:
model = InvoiceItem
class InvoiceSerializer(serializers.ModelSerializer):
items = InvoiceItemSerializer(many=True)
class Meta:
model = Invoice
def create(self, validated_data):
items = validated_data.pop('items', None)
invoice = Invoice(**validated_data)
invoice.save()
for item in items:
InvoiceItem.objects.create(invoice=invoice, **item)
return invoice
</code></pre>
<p>Up till now, the create/read/delete methods work perfectly, except the <code>update</code>.
I think the below logic should be correct, but it misses something.</p>
<pre><code>def update(self, instance, validated_data):
instance.nr = validated_data.get('nr', instance.nr)
instance.title = validated_data.get('title', instance.title)
instance.save()
# up till here everything is updating, however the problem appears here.
# I don't know how to get the right InvoiceItem object, because in the validated
# data I get the items queryset, but without an id.
items = validated_data.get('items')
for item in items:
inv_item = InvoiceItem.objects.get(id=?????, invoice=instance)
inv_item.name = item.get('name', inv_item.name)
inv_item.price = item.get('price', inv_item.price)
inv_item.save()
return instance
</code></pre>
<p>Any help would be really appreciated.</p>

CSS doesn't block rendering on Firefox Quantum : <p>With Firefox Quantum I noticed a "glitch" on loading the CSS of some websites.</p>
<p><strong>One of these is <a href="https://www.doveconviene.it/discount" rel="noreferrer">my company's website</a>:</strong></p>
<p><a href="https://i.stack.imgur.com/OyNr1.gif" rel="noreferrer"><img src="https://i.stack.imgur.com/OyNr1.gif" alt="DoveConviene Website"></a></p>
<p><strong>Or Github too:</strong></p>
<p><a href="https://i.stack.imgur.com/VrRYC.gif" rel="noreferrer"><img src="https://i.stack.imgur.com/VrRYC.gif" alt="Github Website"></a></p>
<p>In the first one, we have only one CSS file in the <code><head></code> section of our pages.</p>
<p>It seems that - only in Firefox Quantum - the CSS doesn't block the render of the page <a href="https://developers.google.com/web/fundamentals/performance/critical-rendering-path/render-blocking-css" rel="noreferrer">as it should</a>. The rest of the page loads without the CSS for some instants, then the CSS is applied as if it loads asynchronously (but it's not).</p>
<p>Obviously, this behavior doesn't happen in all the websites I visited.</p>
<p>I really have no clue what's going on :)</p>

react bootstrap readonly input within formcontrol : <p>I am using react bootstrap and this framework provides some nice FormControls.</p>
<p>But I would like to make the Input field that is generated within the FormControls to have a prop of readonly="readonly". This way, this field looks the same as my other FormControls, but does not give a keyboard input on IOS. </p>
<p>In my case, the input will be provided by a calendar picker which will be triggered by an popover.</p>
<p>Does anyone know how to give FormControl the parameter readonly="readonly", so that the generated Input field in the browser will have the prop readonly="readonly"?</p>
<p>Many thnx for the answers!</p>

Multiple PayPal Payments Same Receiver : I manage a Nopcommerce site that uses the PayPal Express checkout plugin. Our accounting department wants the ability to split the payments based on some business rules. This differs from PayPal's Adaptive Payments because in this case its multiple payments for the same receiver. Ultimately I would need to capture the transaction ids for each payment to process later on.
Is this possible to do? | 0debug |
How to check if a string contains three chars in consecutive order within a given string in any location? : <p>I am working on an app integration with a website. Basically, I am a PHP developer but the android app is using Java and I am not very professional in it. I need to offer an option to change passwords via the app itself.
When the user enters a new password as a string, I want the app to check and make sure that no three consecutive chars from the old password are repeated in the new password in the same order.</p>
<p>Eg. If a user has the old password "Angel173MN", he/she cannot opt for any new password that contains any three chars like nge,l17,73M etc (same order as in the old password, however, the same chars in other orders is permitted eg. gen, 7l1, 3M7 etc)</p>
<p>The upper/lower case is of no concern here. Can anyone please guide me how to do it?</p>

How do I create a client server network in Swift, or how do I send a request to another iphone on the app? : <p>I'm trying to create an app like uber, and I'm having trouble with the iphone to iphone connection. How am I to send a request to another Iphone, saying I am your driver! Am I to have riders become accepted, and add them to some database of riders in which drivers can see them? Basically I just want a little explanation on the ways I can use swift to connect iphones, any help is appreciated. </p>

Does Go have exceptions during overflow for arythmetic operations : I ma just porting some Go code to Rust and I realized that when Rust rise overflow during multiplication exception Go just allow overflow to happen.
Test code below, that does not cause overflow but print reduced value.
(tested via: https://play.golang.org/)
```
func main() {
fmt.Println("test\n")
var key uint64 = 15000;
key = key*2862933555777941757 + 1
fmt.Println(key)
}
```
Is that expected behavior? Sorry for basic question but I don't have much Go Experience. | 0debug |

How to keep matplotlib (python) window in background? : <p>I have a python / matplotlib application that frequently updates a plot with new data coming in from a measurement instrument. The plot window should not change from background to foreground (or vice versa) with respect to other windows on my desktop when the plot is updated with new data.</p>
<p>This worked as desired with Python 3 on a machine running Ubuntu 16.10 with matplotlib 1.5.2rc. However, on a different machine with Ubuntu 17.04 and matplotlib 2.0.0, the figure window pops to the front every time the plot is updated with new data.</p>
<p>How can I control the window foreground/background behavior and keep the window focus when updating the plot with new data?</p>
<p>Here's a code example illustrating my plotting routine:</p>
<pre><code>import matplotlib
import matplotlib.pyplot as plt
from time import time
from random import random
print ( matplotlib.__version__ )
# set up the figure
fig = plt.figure()
plt.xlabel('Time')
plt.ylabel('Value')
plt.ion()
# plot things while new data is generated:
t0 = time()
t = []
y = []
while True:
t.append( time()-t0 )
y.append( random() )
fig.clear()
plt.plot( t , y )
plt.pause(1)
</code></pre>

How to find out how many bits are set (equal 1) in the product of two integers : <p>I am looking for an algorithm solution to find out how many bits are set (equal 1) if I multiply two integers. I have numbers A and B, between 0 and MAX_INT, to eliminate the negative numbers. How do I find out how many bits will be set in the product C = A * B.</p>
<p>-of course calculating C and counting the bits is not the correct solution, it won't work for high values</p>
<p>-I work in C and C++, but it is a rather general algorithm problem. I must solve it without any math/boost library help.</p>
<p>Tried finding a general solution to know the bit count, but what I guessed only worked for quite some examples, it entirely failed with high numbers.</p>

when should we use semaphore vs Dispatch group vs operation queue ? [Swift iOS] : when should we use semaphore vs Dispatch group vs operation queue ?
i am aware of part how all of them works, but i am not sure when to use which option. since all of the things i can achieve with semaphore can also be achieved through dispatch group and also through operation queue.
Is there any specific area when each one should be preferred over other ? | 0debug |

How to automatically size Icons in Flutter to be as big as possible : <p>At the moment, I am using the following bit of code : </p>
<pre><code> body: new Container(
child: new Column(
crossAxisAlignment: CrossAxisAlignment.stretch,
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: <Widget>[
new MaterialButton(
height: 120.0,
child: new Column(
children: <Widget>[
new Icon(
Icons.av_timer,
size: 100.0,
),
new Text('TIMER'),
],
),
onPressed: null,
),
new MaterialButton(
height: 120.0,
child: new Column(
children: <Widget>[
new Icon(Icons.alarm_add, size: 100.0),
new Text('ALARM'),
],
),
onPressed: null,
)
])));
</code></pre>
<p>However, I have had to "hardcode" the Icon size to 100.0 and the height of the MaterialButton to 120.0. </p>
<p>I would like the MaterialButton to take as much space as possible (50% of the screen for each), and I would like the Icons to "fit nicely" in that space, ideally along with the Text scaling as well. </p>
<p>I haven't found the way to do that in Flutter yet. If it's not a good idea to try to do this (I would like it to use the entire space of the screen on any device) please let me know why ? </p>

What is the purpose of curdoc()? : <p>I've been playing with bokeh for a little bit of time and I'm now at the step where I'd like to create interactive plots and embed them online (in WordPress posts, for example).</p>
<p>However, even though I spent some time reviewing and testing code from the bokeh website examples, I have a hard time understanding exactly what is the purpose of curdoc(). It seems to be necessary in order to create a bokeh app with widgets, but from what I found in the ressources, I don't quite understand it.</p>

Send cookie in HTTP POST Request in javascript : <p>I am trying to make a POST request to the server (Which is a REST service)via javascript,and in my request i want to send a cookie.My below code is not working ,as I am not able to receive cookie at the server side.Below are my client side and server side code.</p>
<p><strong>Client side :</strong></p>
<pre><code>var client = new XMLHttpRequest();
var request_data=JSON.stringify(data);
var endPoint="http://localhost:8080/pcap";
var cookie="session=abc";
client.open("POST", endPoint, false);//This Post will become put
client.setRequestHeader("Accept", "application/json");
client.setRequestHeader("Content-Type","application/json");
client.setRequestHeader("Set-Cookie","session=abc");
client.setRequestHeader("Cookie",cookie);
client.send(request_data);
</code></pre>
<p><strong>Server Side:</strong></p>
<pre><code>public @ResponseBody ResponseEntity getPcap(HttpServletRequest request,@RequestBody PcapParameters pcap_params ){
Cookie cookies[]=request.getCookies();//Its coming as NULL
String cook=request.getHeader("Cookie");//Its coming as NULL

RxSwift minimal Observable.create example : <p>Currently I am trying to get RxSwift working. And I want to create a custom Observable. But I think I am doing something wrong. </p>
<p>I have distilled what I do to this minimal sample:</p>
<pre><code>import Foundation
import RxSwift
class Example
{
let exampleObservable : Observable<String> = Observable.create { (observer) in
observer.on(.Next("hello"))
observer.on(.Completed)
return AnonymousDisposable { }
}
let exampleObserver : AnyObserver<String>?
func run()
{
self.exampleObserver = exampleObservable.subscribeNext({ (text) -> Void in
print(text)
})
}
}
let ex = Example()
ex.run()
</code></pre>
<p>Is this correct? In the run method, the subscribeNext method is autocompleted that way by XCode.</p>
<p><a href="https://i.stack.imgur.com/kMKjb.png"><img src="https://i.stack.imgur.com/kMKjb.png" alt="Example"></a></p>
<p>But when I run it I get the following compilation error: </p>
<pre><code>Cannot Invoke 'substribeNext' with an argument list of type ((String) -> Void)

What is Best way to return Data in webapi : <p>I have a question that what is the best way to return data in webapi.
for eg we can have 2 scenarios.</p>
<blockquote>
<p>1) GetProductsById in which we recive an id and return data for that Id.</p>
<p>2) GetProducts in which we return list of data</p>
</blockquote>
<p>so for GetProductsById we can do : </p>
<pre><code> public IHttpActionResult GetProduct(int id)
{
var product = getProducts().FirstOrDefault((p) => p.Id == id);
if (product == null)
{
return NotFound();
}
return Ok(product);
}
</code></pre>
<p>and for getting list:</p>
<pre><code> public IHttpActionResult GetProduct(int id)
{
var products = getproducts();
if (products == null)
{
throw new NotFoundException()
}
return Ok(product);
}
</code></pre>
<p>I want to know the best method to handle not found scenario in both cases.</p>

Few questions about Visual Studio 2015 Git : <p>I started to use Git provided in Visual Studio 2015 Update 2. My team consists of only me. My needs are simple: to have history of changes, and possibility to revert them. Visual Studio created automatically local repository in my solution directory. My questions are:</p>
<ol>
<li><p>Is it valid way to use only local repository? Will it create any problems when I never set up remote repository?</p></li>
<li><p>Is .git folder created in solution directory independent? I mean, does it have complete git information, so when I copy to another directory or machine, it will have its own full state?</p></li>
<li>In case of backups, will be there any difference between: a) simply setting a 3rd party program to backup whole solution directory to remote server. b) setting up server for remote repository, and backuping by commiting changes.</li>
<li><p>Why .git folder is hidden?</p></li>
<li><p>How can I hide field showing number of unpublished commits, which is located on the right bottom in Visual Studio 2015 Update 2? If I will never set up remote server, this number will increase to huge numbers, and reminds me about elapsing time.</p></li>

Acceleration in Unity : <p>I am trying to emulate acceleration and deceleration in Unity.</p>
<p>I have written to code to generate a track in Unity and place an object at a specific location on the track based on time. The result looks a little like this.</p>
<p><a href="https://i.stack.imgur.com/1syKu.png" rel="noreferrer"><img src="https://i.stack.imgur.com/1syKu.png" alt="Cube mid way through Catmull-Rom Spline"></a></p>
<p>The issue I currently have is that each section of the spline is a different length and the cube moves across each section at a different, but uniform, speed. This causes there to be sudden jumps in the change of the speed of the cube when transitioning between sections.</p>
<p>In order to try and fix this issue, I attempted to use <a href="https://gist.github.com/xanathar/735e17ac129a72a277ee" rel="noreferrer">Robert Penner's easing equations</a> on the <code>GetTime(Vector3 p0, Vector3 p1, float alpha)</code> method. However, whilst this did help somewhat, it was not sufficient. There were still jumps in speed in between transitions.</p>
<p>Does anyone have any ideas on how I could dynamically ease the position of the cube to make it look like it was accelerating and decelerating, without large jumps in speed between segments of the track?</p>
<hr>
<p>I have written a script that shows a simple implementation of my code. It can be attached to any game object. To make it easy to see what is happening when the code runs, attach to something like a cube or sphere.</p>

Create new instance of class on calling a method c# : I have a Console Application which is injecting all the service through the constructor. I am also creating and initializing a Dictionary in the Constructor of my data access class.
I am calling the data access method from my main class but I wanted to create a new instance of data access class and therefore dictionary whenever I will call the method GetData().
public class Startup
{
private static void Main(string[] args)
{
ServiceCollection serviceCollection = new ServiceCollection();
ConfigureServices(serviceCollection);
IServiceProvider serviceProvider = serviceCollection.BuildServiceProvider();
serviceProvider.GetService<MyService>().Start();
}
private static void ConfigureServices(IServiceCollection serviceCollection)
{
serviceCollection.AddTransient<IMyServiceDataAccess, MyServiceDataAccess>();
serviceCollection.AddTransient<MyService>();
}
}
MyServiceClass:
private readonly IMyServiceDataAccess _dataAccess;
public MyService(IMyServiceDataAccess dataAccess)
{
_dataAccess = dataAccess;
}
public void Start()
{
var data = _dataAccess.GetData();
}
DataAccess interface
public interface IMyServiceDataAccess
{
List<int> GetData();
}
DataAccess class:
Dictionary<bool,List<int> dict;
public MyServiceDataAccess()
{
dict = new Dictionary<bool,List<int>>()
}
public List<int> GetData()
{
// have to access the above dict and everytime I need new instance
// of this dict
}
This will be multithreaded application so multiple threads can share the dictionary. One way is that create new instance of dictionary in get data method everytime it is called.

How to create copies of the images. : Say i have different classes of medical x ray images, but they are not equal in number. Some class of images (Image Count) are in 1000's, some are in 100's, some are below 50 and 10. How i can make them equal.? Means i need to create copies of the images. Which is the best method for this. After that i need to do feature extraction. So if i have good number of images in each class i can train well i guess.
Since x ray images are taken in different angle, mean while i am thinking how can i make some rotation to the existing images when creating duplicate images. | 0debug |

Compute the maximum possible value of E1 + E2 + ... + EN. If it's impossible to pick the elements E1, E2, ..., EN, print -1 instead.
and a constraint:
You should pick N elements, one from each sequence; let's denote the element picked from sequence Ai by Ei. For each i (2 ≤ i ≤ N), Ei should be strictly greater than Ei-1.
does this constraint mean we have to choose max element from each line?
If you look at example given:
Example
Input:
1
3
1 2 3
4 5 6
7 8 9
Output:
18
Explanation
Example case 1: To maximise the score, pick 3 from the first row, 6 from the second row and 9 from the third row. The resulting sum is E1+E2+E3 = 3+6+9 = 18.
if you notice they have mentioned "maximize".
Though my code finds the max, it isn't being accepted.

Getting form data on submit? : <p>When my form is submitted I wish to get an input value:</p>
<pre><code><input type="text" id="name">

<p>I know I can use form input bindings to update the values to a variable, but how can I just do this on submit. I currently have:</p>
<pre><code><form v-on:submit.prevent="getFormValues">
</code></pre>
<p>But how can I get the value inside of the getFormValues method?</p>
<p>Also, side question, is there any benefit to doing it on submit rather than updating variable when user enters the data via binding? </p>
