How to make UILabel resize to fit text : <p>I have a UILabel that I have layed out in a storyboard centred in the view. It has some initial text "tap to login".</p>
<p>I am changing the value of the label to be the user's name once they have logged in. Once I do this, the label is no longer centered as the UILabel has not changed size.</p>

R:Hoe to arrange a data frame in order to display columns : i have the following code and data frames
CONSUMO<-data.frame( 9914282, 10375040, 10618441, 10547759)
INVERSION<-data.frame( 2860302

IMPORTACIONES<-data.frame(3966992, 4183838,4244597,4274534)
EXPORTACIONES<-data.frame( 9914282, 4168771,4217287, 4427378)
PIB<-(CONSUMO+INVERSION+EXPORTACIONES-IMPORTACIONES)
PIB
## X9914282 X10375040 X10618441 X10547759

PERIODO<-data.frame(2011,2012,2013,2014)
I use this code to put all the data together
Tabla7<-data.frame(c(PERIODO,CONSUMO,INVERSION, EXPORTACIONES,
IMPORTACIONES, PIB))
it is displayed like this:
Tabla7
## X2011 X2012 X2013 X2014 X9914282 X10375040 X10618441 X10547759 X2860302

## X10547759.1
## 1 13617631
and my question is how to display the new data frame that looks like a table, so PERIODO CONSUMO INVERSION EXPORTACIONES IMPORTACIONES PIB quantities are displayed in different columns and its values shown vertically.
many thanks in advance.

File manipulation using Python : <p>I recently started working in a lab that generate a lot of data. I need to manipulate files very often for various needs. I have learnt awk programming but it seems not enough for my work. I know python but not to that extent where I can comfortably work on files. Could anyone please suggest to me any book or online tutorial where I can find exclusively the use of Python on files. most of the python books do not dwell intensively on this subject.
thanks</p>

how to resize a range to a specific column : I have data in a range from B2:P10.
If i select a cell (for example c3), what is the vba code to select right to column p (so c3:p3).
There is text in column q so i cant select right to the 'end'.
i've tried using offset and resize functions but everything i try is relative and doesnt stop at the absolute of column P | 0debug |

bool b = bool(t);
bool b(t); // converting initialiser
bool b{static_cast<bool>(t)};

/* statement */;

<p>Where else can I use <code>t</code> as a <code>bool</code> without a cast?</p>

When can a base class have a different layout than the corresponding complete object type? : <p>GCC and Clang do not perform C++17’s guaranteed copy elision when a base class constructor is called; see <a href="https://stackoverflow.com/questions/46065704/why-isnt-rvo-applied-to-base-class-subobject-initialization">this question</a> and the corresponding <a href="https://bugs.llvm.org/show_bug.cgi?id=34516" rel="noreferrer">Clang bug report</a> for details.</p>
<p>In response to the bug report, <a href="https://bugs.llvm.org/show_bug.cgi?id=34516#c1" rel="noreferrer">Richard Smith states</a>:</p>
<blockquote>
<p>This is a defect in the standard wording. Copy elision cannot be guaranteed when initializing a base class subobject, because base classes can have different layout than the corresponding complete object type.</p>
</blockquote>
<p>Under what circumstances can a base class have a “different layout than the corresponding complete object type” in a way that makes guaranteed copy elision impossible? Is there a concrete example that illustrates this?</p>

How do I generate the first 12 numbers in the sequence 1, 1, 1, 2, 2, 3, 4, 5, 7, 9 using a while loop? : <p>I have figured out the formula to work the sequence out which is the use the each number in the sequence uses the previous previous previous number + the previous previous number for example to get the number 4 you use the previous x3 number which is the first 2 in the sequence plus the previous x2 number which is the second 2 in the sequence. I understand that I have to use 4 variables and then swap the number accordingly in the loop but i cant quite figure out how to do so.
Here is what I have so far.</p>
<pre><code> System.out.print("Loop for the first 12 terms of sequence 1, 1, 1, 2, 2, 3, 4, 5, 7, 9\n");
int p0, p1, p2, p3, c;// c in control p is num is sequence.
c=0;
p0=1;
p1=1;
p2=1;
p3=p0+p1;
while(c<=12){
System.out.print(p0+","+p1+","+p2+","+p3+",");
c++;
}
</code></pre>
<p>which just gives me the first 4 numbers of the sequence 12 times. Do I have to use an entirely different while loop for the next numbers or can I do it in the same loop?
any help appreciated. Thank you.</p>

What is Docker.qcow2? : <p>I was looking at my disk with DaisyDisk and I have a 30GB something called Docker.qcow2. More specifically, DaisyDisk puts it under <code>~/Library/Containers/com.docker.docker/Data/vms/0/Docker.qcow2</code>. Is it some kind of cache? Can I delete it? I have a lot of images from old projects that I won't ever use and I'm trying to clear up my disk.</p>

Accesing variables and methods between classes using reference and singleton : <p>I'm struggling with using variables and methods between classes. For example, let's focus on variable only. I have two classes, <code>Foo</code> and <code>Bar</code>. I have constantly changing variable in <code>Foo</code> named <code>number</code>. How do I access this variable from class <code>Bar</code>? There will be always only one instance of <code>Bar</code> class.</p>
<pre><code>class Foo {
private Bar bclass;
public int number = 0;
Foo() {
bclass = new Bar();
}
}
class Bar {
Bar() {
// code
// Access Foo's number from here
}
}
</code></pre>
<p>There are a few options that I can think of. First - Singleton pattern. I can make all methods and variables static, make constructor private and make only one instance. Second solution would be passing <code>number</code> as reference via constructor. But that doesn't solve my problem with accessing methods in <code>Foo</code>. Or i could pass whole instance of <code>Foo</code> to <code>Bar</code> via constructor like this:</p>
<pre><code> Bar(Foo firstClass) {}
// Then in Foo
bclass = new Bar(this);
</code></pre>
<p>My program is using 4 different classes, all of them will have always only one instance and all of them need to communicate with main class or between each other in some way (using it's variables or methods). Which approach would you recommend me? Making all 4 classes as Singletons?</p>
<p>Sorry if the title or text is confusing, if I missed something it something isn't clear I will gladly respond or edit my question.</p>

java, best API jar : <p>I'm building one API using javax.ws.rs-api(2.1.1) and com.sun.jersey (1.18.1) but it causes one Exception. Reading some threads it seems like one of both includes one class that is part of the other and this raises this Exception.
After some tries I'm still stucked on find how to fix it but then another question came to my brain, Is this the best API class for building servlets? So my question is if somebody can provide his experience and can say that continue using those libraries is the best option (and then fight for fixing this Exception) or can suggest better options.</p>
<p>I'm not using Spring neither Hibernate and those are not the option, I build my own Servlet from scratch ... yes ... I have my reasons ....</p>

Turning a simple python "program" in a C "program"! : <p>So i have this "program" in python3 which adds 3 strings but the middle part x times. But i decided to choose C as my first language after doing some simple stuff on Python 3.
NOW this is how it looks in Python:</p>
<pre><code>def printWord(begin, mid, end, r):
print(begin, end="")
for i in range(r+1):
print(mid, end="")
print(end)
begin = input("Enter your beginning.\t")
mid =input("Enter your middle.\t")
end = input("Enter your ending.\t")
r = int(input("How many times?\t"))
printWord(begin, mid, end, r)
</code></pre>
<p>So this works and every thing is cool!</p>
<p>Now C:</p>
<pre><code>#include <stdio.h>
#include <stdlib.h>
int makeWord(char begin[], char mid[], char end[], int r)
{
int i;
printf("%s", begin);
for(i=0;i<=r;i++){
printf("%s", mid);
}
printf("%s", end);
return 0;
}
int main()
{
int r;
char begin[3], mid[2], end[3];
printf("Enter the beginning!\t");
scanf("%s", begin);
printf("Enter the middle!\t");
scanf("%s", mid);
printf("Enter the ending!\t");
scanf("%s", end);
printf("How many times?\t");
scanf("%d", r);
makeWord(begin, mid, end, r);
return 0;
}
</code></pre>
<p>But this one stops </p>
<p>Now my question WHY?
Thanks for answering</p>

complex API vs simple API endpoint : <p>I have a backend Rails application that is mainly API endpoints and a front-end application that is mainly being built in React.</p>
<p>Consider the following models:</p>
<ol>
<li><strong>Panel</strong>: is an container element inside a dashboard. It defines dimensions/positions inside the dashboard. It also defines its content using a content_type and a content_id (polymorphic associations).</li>
<li><strong>Chart / SingleValue / Section</strong>: these are all models that can be used as content for the panel. </li>
</ol>
<p>What I would like to do now is letting the user create a "chart panel" in one step.</p>
<p>I've been wondering for a while now if it is better to:</p>
<ol>
<li>Have all the basic CRUD API end-points and manage the panel+chart creation 100% on the front-end. This would mean more complexity on the front-end but fewer API end-points.</li>
<li>Have an extra API endpoint on the Rails side to create panel+chart/panel+single_value/panel+section (atomic operation). This would mean much less complexity on the front-end but more API end-points.</li>
</ol>
<p>What would be the ideal approach?</p>

What is the ideal target time for rendering a page of a PHP forum? : <p>I am creating this question because I am currently working on my free time (for fun) on a PHP forum, using MySQL for my database. And for a little while now (most of the essential features being implemented), I have been questioning the performance of my scripts.</p>
<p>I already did some profiling of my scripts and improved some of them, but I eventually always end up with the same question: <strong>what is a good target time to render the typical page of a forum ?</strong> In my case, such a page consists in displaying 20 to 50 messages of a given topic (users can decide how many messages per page they want to display) with roughly half of them using features like uploads displayed as a gallery below a message (which involves string parsing and checking the existence of a file with file_exists()).</p>
<p>After reading some topics on performance with PHP on this website, I learned, among others, that Youtube had a target render time of 100ms (= 0,1s). I managed to have load times below this target time for my heaviest pages, but only after a while due to PHP caching with file_exists() (I run my project locally, with a WAMP Server). But I doubt I can really compare my project to a website as heavy in features as Youtube. So,</p>
<ul>
<li><p>When rendering (in HTML/CSS) my "typical" page, what time should I target ? Is it acceptable to stick to the 100ms limit, or should I go way below (for example, below 50ms) ? Are there any known statistics about current state-of-the-art forums I could use for reference ?</p></li>
<li><p>Since I am currently working with WAMP Server, does it introduce bias while profiling my scripts ? Is it equivalent to your average PHP-enabled HTTP server, or does it run slower/faster on average ?</p></li>
</ul>
<p>This question interests me a lot, as some features I designed add some overhead to my scripts (which scales with the amount of messages being displayed). For example, my format code to embed videos is not parsed at the creation of a message, but at its display, as I want to be able to easily change the embed code as well as allowing users to choose how videos are embedded (directly, or with small/HQ thumbnail which is replaced with the embed code upon clicking) for their comfort. Of course, I could as well parse the code at the submission of a new message to reduce the overhead, but I want to be sure this is necessary.</p>
<p>I hope this is not too vague... thank you in advance for your answers.</p>

npm publish Failed PUT 402 : <p>Working on a course that is having me go through a Bash tutorial.
I am stuck on the part where the code is asking me to publish my code so far. My instructions are as follows:</p>
<blockquote>
<pre><code> What good is a package manager without packages?
Not very good.
Luckily, that is not a problem for npm, because it's very easy for all
npm users to publish their modules and share them with the world.
Packages get into the registry by using the `npm publish` command.
Try it now. There's not much to it.
(Make sure you're still in the right project directory, though. If you
publish something by mistake, you can remove it, but there's no guarantee
that no one saw it in the meantime.)
Then run `how-to-npm verify` when you're done.

iTextSharp - how to have space padding at the top & bottom of a columnText : I am writing text into a ColumnText using
columnText.AddElement(paragraph);
I would like to have some padding (blank space) at the top and bottom of the column, bearing in mind that I am writing many paragraphs before reaching the bottom of the column.
I would appreciate it if you give me an idea how to achieve this.
Thanks

Split a string and loop through values in MySql Procedure : <p>I got a situation where I have to pass a comma separated string to MySQL procedure and split that string and insert those values as rows in to a table.</p>
<p>As show below</p>
<p>For example if I passed 'jhon,swetha,sitha' string to mysql procedure then it have to split that string by comma and insert those values as 3 records into a table.</p>
<pre><code> CREATE PROCEDURE new_routine (IN str varchar(30))
BEGIN
DECLARE tmp varchar(10);
DECLARE inc INT DEFAULT 0;
WHILE INSTR(str, ',') DO
SET tmp = SUBSTRING(SUBSTRING_INDEX(str,',',inc),LENGTH(SUBSTRING_INDEX(str,',',inc-1))+1),',','');
SET str = REPLACE(str, tmp, '');
//insert tmp into a table.
END WHILE;

C Installed Library - What is this? : <p>I'm currently trying to install a library in c (specifically libsndfile). It's telling me that I need to 'install' and library. I'm confused, what exactly am I doing by 'installing' the library? </p>
<p>Why is it that I'm not just including header and source code files? </p>
<p>I've tried googling this but have not gotten too much success. Does anyone care to explain or recommend an article that discusses this?</p>
<p>Thank you,</p>

How to do multiple word and value replacement in a multiple line at one time :
Lets say I have multiples like this
my input lines:
"stack overflow version {5} my new version"
"stack exchnage version {10} my new version"
"perl scripting version 5.14 my new version"
"segmentaion falult happen {5} if the memory is not freed"
" my college 30 new xxxx"
I want to replace value inside parenthesis and the value is not
constant it will be vary by file by file.
`My Approaches`:
use strict;
use warnings;
my $old_parameter='stack overfolw version';
my $new_parameter;
my $old_value={5};
my $new_value=' ';
my $filename ='input.txt'
open my $fh, "<", $filename or die "Couldn't open input file: $!";my file
while<FH>
{
if ($old_parameter) and ($old_value)
{
s/($old_value)/(new_value);
}
the above code will replace the value if the value is constant but if the
value is vary lets say (1--100) and also I want to do
replacement at one time all the line.
then what would be the best approach ?
