Can two terminal windows running on the same OS at the same time, communicate with one another? : <p>I was wondering if it's possible to send a young message such as "hello world" from one terminal/cmd window to another terminal/cmd window - both running at the same time on the same operating system?</p>
<p>I'm using mac OSX and have access to a linux OS. </p>

iOS 11 UIBarButtonItem images not sizing : <p>The answer to my question was hinted at in <a href="https://stackoverflow.com/questions/45759482/how-to-set-uibarbutton-size-in-ios-11-to-match-size-in-ios-10">this question</a>, so I think the answer is to disable autolayout for my UIToolbar view. </p>
<p>The code that is said to work for views is</p>
<pre><code>cButton.translatesAutoresizingMaskIntoConstraints = YES;
</code></pre>
<p>But I’m not sure if it applies to my code since UIToolbar doesn’t inherit from UIView.</p>
<p>I have lots of small images that I use in my games that are different sizes depending on the device and orientation. Rather than having lots of different images, and adding new ones when Apple introduces new devices, I decided to make one 160x160 image fore each and then resize it when it is used. This worked fine from iOS 4 - iOS 10 but fails in iOS 11.</p>
<p>The code is pretty straightforward:</p>
<pre><code>// Get the image
NSString *pictFile = [[NSBundle mainBundle] pathForResource:@"Correct" ofType:@"png"];
UIImage *imageToDisplay = [UIImage imageWithContentsOfFile:pictFile];
UIImage *cImage = [UIImage imageWithCGImage:imageToDisplay.CGImage scale:[UIScreen mainScreen].scale orientation:imageToDisplay.imageOrientation];
UIButton *cButton = [UIButton buttonWithType:UIButtonTypeCustom];
[cButton setImage:cImage forState:UIControlStateNormal];
[cButton setTitle:@"c" forState:UIControlStateNormal];
//set the frame of the button to the size of the image
cButton.frame = CGRectMake(0, 0, standardButtonSize.width, standardButtonSize.height);
//create a UIBarButtonItem with the button as a custom view
c = [[UIBarButtonItem alloc] initWithCustomView:cButton];
</code></pre>
<p>This is what it looks like pre11. The bar button items have been resized and fit nicely in the bottom bar. Note I reduced the size of the checkmark by 50% just to make sure I was looking at the correct code and that it behaves like I expect.</p>
<p><a href="https://i.stack.imgur.com/phDsI.jpg" rel="noreferrer"><img src="https://i.stack.imgur.com/phDsI.jpg" alt="correct version"></a></p>
<p>Here’s what they look like in the simulator for Xcode 9.0 GM and iOS 11. Note that the top row of buttons resize correctly but the bottom row expand to fill the space allocated for the tab bar. The same behaviour happens on iPads as well and various devices. </p>
<p><a href="https://i.stack.imgur.com/SpiY4.jpg" rel="noreferrer"><img src="https://i.stack.imgur.com/SpiY4.jpg" alt="iOS 11"></a></p>
<p>Any ideas about how to disable Autolayout or add constraints?</p>

Java 10 migration from Java 8. Running services in production : <p>We want to migrate all our production services to Java 10 from Java 8. As I understood, we might face issues with builds (gradle etc.), dependencies etc. for development. But when it comes just to the JVM itself, i.e. running services, will we face any issues if we just install JVM 10 in production to run our jar services?</p>

New Ruby on Rails Setup : "Expected string default value for '--rc'; got false (boolean)" : <p>I'm setting up a Ruby on Rails web development environment on a new machine (macOS Sierra v. 10.12.1). I'm following the setup instructions here: <a href="https://gorails.com/setup/osx/10.12-sierra">Setup Ruby On Rails on macOS 10.12 Sierra</a>. When I check the newly installed rails version, I get the following:</p>
<pre><code>$ rails --version
Expected string default value for '--rc'; got false (boolean)
Rails 4.2.6
</code></pre>
<p>I haven't seen that second line before, and googling hasn't yielded any helpful results. Background information: clean install of macOS 10.12.1; installed xcode via the App Store; installed Homebrew via the instructions on <a href="http://brew.sh/">its homepage</a>; installing Ruby, Rails, etc. via the first link I mentioned.</p>
<p>Anyone have any idea what might be going on?</p>

What flavor of Regex does Visual Studio Code use? : <p>Trying to search-replace in Visual Studio Code, I find that its Regex flavor is different from full Visual Studio. Specifically, I try to declare a named group with <code>string (?<p>[\w]+)</code> which works in Visual Studio but not in Visual Studio Code. It'll complain with the error <code>Invalid group</code>.</p>
<p>Apart from solving this specific issue, I'm looking for information about the flavor of Regexes in Visual Studio Code and where to find documentation about it, so I can help myself with any other questions I might stumble upon.</p>
<p>Full Visual Studio uses .NET Regular Expressions as documented <a href="https://msdn.microsoft.com/en-us/library/2k3te2cs.aspx" rel="noreferrer">here</a>. This link is mentioned as the documentation for VS Code elsewhere on Stackoverflow, but it's not.</p>

How to share conda environments across platforms : <p>The conda docs at <a href="http://conda.pydata.org/docs/using/envs.html" rel="noreferrer">http://conda.pydata.org/docs/using/envs.html</a> explain how to share environments with other people.</p>
<p>However, the docs tell us this is not cross platform:</p>
<pre><code>NOTE: These explicit spec files are not usually cross platform, and
therefore have a comment at the top such as # platform: osx-64 showing the
platform where they were created. This platform is the one where this spec
file is known to work. On other platforms, the packages specified might not
be available or dependencies might be missing for some of the key packages
already in the spec.
NOTE: Conda does not check architecture or dependencies when installing
from an explicit specification file. To ensure the packages work correctly,
be sure that the file was created from a working environment and that it is
used on the same architecture, operating system and platform, such as linux-
64 or osx-64.
</code></pre>
<p>Is there a good method to share and recreate a conda environment in one platform (e.g. CentOS) in another platform (e.g. Windows)?</p>

FORTRAN ERROR 6837 : Hello I am trying to write a FORTRAN subroutine for ABAQUS that would modify the seepage coefficient and thus the flow depending on whether there is contact on the surface. In order to do so I need 2 subroutines URDFIL to retrieve the node data and FLOW to modify the seepage coefficient.
However, when I compile my subroutine I get the following errors:
flow_us.for(81): error #6837: The leftmost part-ref in a data-ref can not be a function reference. [K_ELE_DETAILS]
IF(K_ELE_DETAILS(E_INDX)%IS_CONT(N_INDX).EQ.0)THEN

flow_us.for(81): error #6158: The structure-name is invalid or is missing. [K_ELE_DETAILS]
IF(K_ELE_DETAILS(E_INDX)%IS_CONT(N_INDX).EQ.0)THEN
Obviously it is repeated for the 3 lines (if's) that contain such structure (81,8, and 89).
Please find the code below and hopefully someone will be able to help

700 000
70 000
700 000
7 000 000 etc

<p>The problem is that I receive the price from json file, so it's always a string. </p>
<p>What I want is to convert that price string into the desired format by RegEx.</p>
<ol>
<li>We invert the price <code>7000000 = 0000007</code></li>
<li>We put a whitespace after 3rd character in the inverted string <code>000 000 7</code></li>
<li>Then we invert the string again and get a normal price format <code>7 000 000</code></li>
</ol>
<p>Is it possible for json data and perhaps there is a more correct way to go? Didn't find any working examples.</p>

ElasticSearch updates are not immediate, how do you wait for ElasticSearch to finish updating it's index? : <p>I'm attempting to improve performance on a suite that tests against ElasticSearch. </p>
<p>The tests take a long time because Elasticsearch does not update it's indexes immediately after updating. For instance, the following code runs without raising an assertion error.</p>
<pre><code>from elasticsearch import Elasticsearch
elasticsearch = Elasticsearch('es.test')
# Asumming that this is a clean and empty elasticsearch instance
elasticsearch.update(
index='blog',
doc_type=,'blog'
id=1,
body={
....
}
)
results = elasticsearch.search()
assert not results
# results are not populated
</code></pre>
<p>Currently out hacked together solution to this issue is dropping a <code>time.sleep</code> call into the code, to give ElasticSearch some time to update it's indexes.</p>
<pre><code>from time import sleep
from elasticsearch import Elasticsearch
elasticsearch = Elasticsearch('es.test')
# Asumming that this is a clean and empty elasticsearch instance
elasticsearch.update(
index='blog',
doc_type=,'blog'
id=1,
body={
....
}
)
# Don't want to use sleep functions
sleep(1)
results = elasticsearch.search()
assert len(results) == 1
# results are now populated
</code></pre>
<p>Obviously this isn't great, as it's rather failure prone, hypothetically if ElasticSearch takes longer than a second to update it's indexes, despite how unlikely that is, the test will fail. Also it's extremely slow when you're running 100s of tests like this.</p>
<p>My attempt to solve the issue has been to query the <a href="https://www.elastic.co/guide/en/elasticsearch/reference/current/cluster-pending.html" rel="noreferrer">pending cluster jobs</a> to see if there are any tasks left to be done. However this doesn't work, and this code will run without an assertion error.</p>
<pre><code>from elasticsearch import Elasticsearch
elasticsearch = Elasticsearch('es.test')
# Asumming that this is a clean and empty elasticsearch instance
elasticsearch.update(
index='blog',
doc_type=,'blog'
id=1,
body={
....
}
)
# Query if there are any pending tasks
while elasticsearch.cluster.pending_tasks()['tasks']:
pass
results = elasticsearch.search()
assert not results
# results are not populated
</code></pre>
<p>So basically, back to my original question, ElasticSearch updates are not
immediate, how do you wait for ElasticSearch to finish updating it's index?</p>

delete a string but the string is not terminated : I need to delete around four thousand lines that contain SEU/C0 among around 25,000 lines
Find SEU in following line:
inpin "SEUC0/example_controller/U0/wrapper_wrappe/genx7.wrapper_controller/pid_reg<3>" A6 ,
But the solution; I tried :
I got this code from this forum suppose to do what I want but no luck
f = open("test.xdl","r+")
d = f.readlines()
f.seek(0)
for i in d:
if i != "SEU": # want to remove the SEU string
f.write(i)
f.truncate()
f.close()
When If if try
i!="inpin SEUC0/
it didn't work because it's a long string, and if I write
"inpin "SEUC0/"" Python gives error.
Is there anyway that I can remove all these lines which contain SEUC0.

<p>There are two parts of the semantics that are not clear to me. First, what bits are "shifted in"?</p>
<ul>
<li>Zeroes are shifted in from one side (i.e. <code>0b1110_1010u8 << 4 == 0b1010_0000u8</code>), or </li>
<li>the bits rotate (i.e. <code>0b1110_1010u8 << 4 == 0b1010_1110u8</code>), or</li>
<li>it's unspecified (like overflowing behavior of integers is unspecified), or</li>
<li>something else.</li>
</ul>
<p>Additionally, how does shifts work with signed integers? Is the sign bit also involved in the shift or not? Or is this unspecified?</p>

How to get text input and past it in front of a link (php) : I'm currently busy with (re)making the dutch Wikipedia site.
And i want to make the search bar.
My idea was to get text input and when you click on search the text will go to the front of a link like this https://ibb.co/XbndsKP
this is currently the search bar:
<!-- begin snippet: js hide: false console: true babel: false -->
<!-- language: lang-html -->
<div align='center'>
<form method="submit" action='php/zoeken.php'>
<input placeholder="zoeken"id="zoeken"class='zoeken'type="text">
<button class='button'type="submit">zoeken</button>
</div>
<!-- end snippet -->

babel-node vs babel-register in development : <p>Is there any difference between using babel-register or babel-node <strong>when running my code in development</strong>? The two options are:</p>
<ol>
<li><p><code>require('babel-register')({
"presets": ["es2015"]
});</code> at entry-point.js and npm start script <code>node entry-point.js</code></p></li>
<li><p>simply have npm start script <code>babel-node entry-point.js --preset=es2015</code></p></li>
</ol>
<p>Do they do the exact same thing? And is one way recommended over the other?</p>

3 Dimensional Dynamic Tkinter Widgets : [Tkinter Requirements][1]
[1]: https://i.stack.imgur.com/WsY2X.png
So I am relatively new to using Tkinter and I am struggling with a very specific doubt here. I tried finding solutions to this but as much as I find it obvious, the solution to this doesn't seem to be easy to understand. So if you can see the image I have linked, I am trying to create a GUI for a particular project which requires multi-layer (I am calling it 3D array based) widgets.
Let's say the variables used for this pointer system are **i, j and k**.
I am creating individual layer widgets using for-loop:
for n in range(i):
frame_x[i] = Frame(root).grid(row = 1, column = i)
entry_x[i] = Entry(frame_x[i]).grid(row = 2, column = i)
button_x[i] = Button(frame_x[i]).grid(row=3, column = i)
**Please note this is not a functional code, I have tried to keep it to the point just to give an idea of the method I am using(Let me know if you want a more detailed code block.**
Now coming to the problem. I am able to do the basic part of this. But the problem is that I want it to work dynamically.
**Lets say if the user enters j = 4 first. 4 blocks will be created.
Later if he changes the value to j = 2 and the presses the button, ideally it should make the widgets at block j= 3 and 4 disappear. But I guess Tkinter works on overlapping basis and doesn't change a grid element until something is specifically overlapped over it. How do I do that. I tried destroying the entire frame just after entering the for-loop but that doesn't work as for the first time no widget is created before destroying and python throws NameError saying I cant use a variable before assignment.**
Anyways, please let me know how do I do this efficiently.
And also in general, if there is a better way to go about the whole thing. Please refer the image linked and let me know if it doesn't make sense.
I am not very comfortable with classes in general. I prefer the inefficient way by only using functions to do everything I have to. So it would be great if you can share me a framework without using classes. But its okay if you use them. I know I should start working with classes at some point.

};
public ref Class B

public:
static A^ a_Instance = gcnew A();
};
And in the C# side, I have create a B instance in order try to use the function in a_Instance as follow.
private B b_instance = new B();
The question is, if it is possible for me to get the instance create in the managed C++ class and use the function in it?

Java Threads producer-consumer shared buffer : <p>Implement producer consumer problem using threads in Java. Producers and consumers share a buffer, producers put elements in buffer and consumers consume elements from the shared buffer. If the buffer is full producers should wait till consumers take out elements, similarly consumers should wait till producers put elements if the buffer is empty.
Your program should accept the following inputs:</p>
<pre><code>m: the number of producer threads
n: the number of consumer threads
k: the size of the bounded buffer
</code></pre>
<p>Your code should prompt for the above inputs in that order. You can assume that a valid integer is provided by the user for each of these. You will need to spawn m Producer threads and n Consumer threads. Each producer generates 20 integers ranging between 0 and 9 and puts them in the buffer. After putting a number in the buffer, it prints its id along with the generated number. The producer sleeps for a random amount of time before repeating the number generating cycle again. Each consumer takes a number from the buffer then prints its id along with the value it got. Then, it sleeps for a random amount of time before reading from the buffer again.
A sample output of the program is:</p>
<pre><code>Producer #2 put: 1
Producer #1 put: 4
Consumer #3 got: 1
Producer #1 put: 3
Consumer #3 got: 4
Consumer #3 got: 3
...
</code></pre>
<p>i have this problem. it is clear that the <strong>array of buffer</strong> is a global variable for two method because of that array is shared with Producer & Consumer. so? Unfortunately i have no idea how to do this project. anybody have an idea?</p>

Python can't find module NLTK to download punkt : I am using PyCharm and Anaconda. I have installed NTLK with sudo `pip install -U nltk` and even to make sure since I'm on Mac OS and I saw [this previous SO post][1] to also try `pip3 install nltk`.
However, no matter where I try (PyCharm's terminal, Pycharm's Python, or my own terminal), I cannot get import ntlk to work and always get `ModuleNotFoundError: No module named 'ntlk'`.
The weird thing is that I actually manage to run some code with a simple "Python test.py" that contains: `from nltk.tag import StanfordPOSTagger` but whenever I try to `import ntlk` to be able to then `nltk.download('punkt')` I get the `No module named 'ntlk'` error.
Would you know where that is coming from?

Kindly help me regarding the code i have given below : i am writing this code for lexical analyzer to detect tokens , identifiers and operater's from a file. But the problem is that when ever i pass the file path and run the code it does't reads the file instead it keeps on giving the output that "UNABLE TO OPEN FILE". Kindly help me
#include<iostream>
#include<fstream>
#include<stdlib.h>
#include<string.h>
#include<ctype.h>
using namespace std;

"sizeof","static","struct","switch","typedef","union",
"unsigned","void","volatile","while"};
int i, flag = 0;
for(i = 0; i < 32; ++i){
if(strcmp(keywords[i], buffer) == 0){
flag = 1;
break;
}
}
return flag;
}
int main(){
char ch, buffer[15], operators[] = "+-*/%=";
fstream inFile;
int i , j =0;

index: true vs foreign_key: true (Rails) : <p>Following a guide, I ran the following command:</p>
<pre><code>rails g migration CreateSnippetsUsers snippet:belongs_to user:belongs_to
</code></pre>
<p>This created the following migration:</p>
<pre><code>class CreateSnippetsUsers < ActiveRecord::Migration[5.0]
def change
create_table :snippets_users do |t|
t.belongs_to :snippet, foreign_key: true
t.belongs_to :user, foreign_key: true
end
end
end
</code></pre>
<p>In the past I've seen the same thing, but with <code>index: true</code> instead of <code>foreign_key: true</code>. What's the difference between the two?</p>

Should i be using trim or other forms of validation to make my forms more secure i been looking at the below or does laravel have a lot more security built into it to help.</p>

C++ Copy constructor gets called instead of initializer_list<> : <p>Based on this code</p>
<pre><code>struct Foo
{
Foo()
{
cout << "default ctor" << endl;
}
Foo(std::initializer_list<Foo> ilist)
{
cout << "initializer list" << endl;
}
Foo(const Foo& copy)
{
cout << "copy ctor" << endl;
}
};
int main()
{
Foo a;
Foo b(a);
// This calls the copy constructor again!
//Shouldn't this call the initializer_list constructor?
Foo c{b};
_getch();
return 0;
}
</code></pre>
<p>The output is:</p>
<p><strong>default ctor</strong></p>
<p><strong>copy ctor</strong></p>
<p><strong>copy ctor</strong></p>
<p>In the third case, I'm putting b into the brace-initialization which should call the initializer_list<> constructor.</p>
<p>Instead, the copy constructor takes the lead.</p>
<p>Will someone of you tell me how this works and why?</p>

Why do const references extend the lifetime of rvalues? : <p>Why did the C++ committee decide that const references should extend the lifetime of temporaries?</p>
<p>This fact has already been discussed extensively online, including here on stackoverflow. The definitive resource explaining that this is the case is probably this GoTW:</p>
<p><a href="https://herbsutter.com/2008/01/01/gotw-88-a-candidate-for-the-most-important-const/" rel="noreferrer">GotW #88: A Candidate For the “Most Important const”</a></p>
<p>What was the rationale for this language feature? Is it known?</p>
<p>(The alternative would be that the lifetime of temporaries is not extended by any references.)</p>
<hr>
<p>My own pet theory for the rationale is that this behavior allows objects to hide implementation details. With this rule, a member function can switch between returning a value or a const reference to an already internally existent value without any change to client code. For example, a matrix class might be able to return row vectors and column vectors. To minimize copies, either one or the other could be returned as a reference depending on the implementation (row major vs column major). Whichever one cannot be returned by reference must be returned by making a copy and returning that value (if the returned vectors are contiguous). The library writer might want leeway to change the implementation in the future (row major vs column major) and prevent clients from writing code that strongly depends on if the implementation is row major or column major. By asking clients to accept return values as const ref, the matrix class can return either const refs or values without any change to client code. Regardless, if the original rationale is known, I would like to know it.</p>
