Convert whole dataframe from lower case to upper case with Pandas : <p>I have a dataframe like the one displayed below: </p>
<pre><code># Create an example dataframe about a fictional army
raw_data = {'regiment': ['Nighthawks', 'Nighthawks', 'Nighthawks', 'Nighthawks'],
'company': ['1st', '1st', '2nd', '2nd'],
'deaths': ['kkk', 52, '25', 616],
'battles': [5, '42', 2, 2],
'size': ['l', 'll', 'l', 'm']}
df = pd.DataFrame(raw_data, columns = ['regiment', 'company', 'deaths', 'battles', 'size'])
</code></pre>
<p><a href="https://i.stack.imgur.com/fiOEt.png" rel="noreferrer"><img src="https://i.stack.imgur.com/fiOEt.png" alt="enter image description here"></a></p>
<p>My goal is to transform every single string inside of the dataframe to upper case so that it looks like this:</p>
<p><a href="https://i.stack.imgur.com/gprF6.png" rel="noreferrer"><img src="https://i.stack.imgur.com/gprF6.png" alt="enter image description here"></a></p>
<p>Notice: all data types are objects and must not be changed; the output must contain all objects. I want to avoid to convert every single column one by one... I would like to do it generally over the whole dataframe possibly.</p>
<p>What I tried so far is to do this but without success</p>
<pre><code>df.str.upper()
</code></pre>

What's difference between tf.sub and just minus operation in tensorflow? : <p>I am trying to use Tensorflow. Here is an very simple code.</p>
<pre><code>train = tf.placeholder(tf.float32, [1], name="train")
W1 = tf.Variable(tf.truncated_normal([1], stddev=0.1), name="W1")
loss = tf.pow(tf.sub(train, W1), 2)
step = tf.train.GradientDescentOptimizer(0.1).minimize(loss)
</code></pre>
<p>Just ignore the optimization part (4th line). It will take a floating number and train W1 so as to increase squared difference.</p>
<p>My question is simple. If I use just minus sign instead of
tf.sub" as below, what is different? Will it cause a wrong result? </p>
<pre><code>loss = tf.pow(train-W1, 2)
</code></pre>
<p>When I replace it, the result looks the same. If they are the same, why do we need to use the "tf.add/tf.sub" things?</p>
<p>Built-in back propagation calculation can be done only by the "tf.*" things? </p>

How does the Shouldly assertion library know the expression the assertion was applied to? : <p>The <a href="http://shouldly.readthedocs.io/en/latest/">Shouldly assertion library for .NET</a> somehow knows what expression the assertion method was called on so it is able to display it into the message. I tried to find out how it works but got lost in the source code. I suspect it looks into the compiled code but I would really like to see how this happens. From the documentation</p>
<pre><code>map.IndexOfValue("boo").ShouldBe(2); // -> map.IndexOfValue("boo") should be 2 but was 1
</code></pre>
<p>Somehow Shouldly knows the expression map.IndexOfValue("boo") and was able to display it in the test failure message. Does anyone know how this happens?</p>

<p>Of course, this works</p>
<pre><code>[[ "$x" == "$x" ]] && echo OK

undefined reference to `startswith' : I am writing some C in which the program is going to convert the first command line argument into a int and check to see if it is an int. If it isnt a integer value it will then attempt to check to see whether the string begins with a '.' character or not. For some reason I am getting an undefined reference. How is this an undefined reference when it seems to be defined?
Here is the following code:
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#include <ctype.h>
#include <string.h>
int startswith(char,char);
int main(int argc, char *argv[])
{
int forst;
srand(time(NULL));
int speed_delay = rand()%20;
printf("The speed delay is:%i\n",speed_delay);
int first = atoi(argv[1]);
printf("First:%i\n",first );
if(first == 0)
{
//this means text was inserted instead of a number
if(startswith(first,'.'))
{
printf("string starts with a period !");
}
}
else
{
}
int startswith( const char *one, const char *two)
{
if(strncmp(one,two,strlen(two)) == 0)

Slicing HTML based on delimiter : <p>I am converting Word docs on the fly to HTML and needing to parse said HTML based on a delimiter. For example:</p>
<pre><code><div id="div1">
<p>
<font>
<b>[[delimiter]]Start of content section 1.</b>
</font>
</p>
<p>
<span>More content in section 1</span>
</p>
</div>
<div id="div2">
<p>
<b>
<font>[[delimiter]]Start of section 2</font>
</b>
<p>
<span>More content in section 2</span>
<p><font>[[delimiter]]Start of section 3</font></p>
<div>
<div id="div3">
<span><font>More content in section 3</font></span>
</div>
<!-- This continues on... -->
</code></pre>
<p>Should be parsed as:</p>
<p>Section 1:</p>
<pre><code><div id="div1">
<p>
<font>
<b>[[delimiter]]Start of content section 1.</b>
</font>
</p>
<p>
<span>More content in section 1</span>
</p>
</div>
</code></pre>
<p>Section 2:</p>
<pre><code><div id="div2">
<p>
<b>
<font>[[delimiter]]Start of section 2</font>
</b>
<p>
<span>More content in section 2</span>
<p></p>
<div>
</code></pre>
<p>Section 3:</p>
<pre><code><div id="div2">
<p>
<b>
</b>
<p>
<p><font>[[delimiter]]Start of section 3</font></p>
<div>
<div id="div3">
<span><font>More content in section 3</font></span>
</div>
</code></pre>
<ol>
<li><p>I can't simply "explode"/slice based on the delimiter, because that would break the HTML. Every bit of text content has many parent elements.</p></li>
<li><p>I have no control over the HTML structure and it sometimes changes based on the structure of the Word doc. An end user will import their Word doc to be parsed in the application, so the resulting HTML will not be altered before being parsed.</p></li>
<li><p>Often the content is at different depths in the HTML.</p></li>
<li><p>I cannot rely on element classes or IDs because they are not consistent from doc to doc. #div1, #div2, and #div3 are just for illustration in my example.</p></li>
<li><p>My goal is to parse out the content, so if there's empty elements left over that's OK, I can simply run over the markup again and remove empty tags (p, font, b, etc).</p></li>
</ol>
<p>My attempts:</p>
<p>I am using the PHP DOM extension to parse the HTML and loop through the nodes. But I cannot come up with a good algorithm to figure this out.</p>
<pre><code>$doc = new \DOMDocument();
$doc->loadHTML($html);
$body = $doc->getElementsByTagName('body')->item(0);
foreach ($body->childNodes as $child) {
if ($child->hasChildNodes()) {
// Do recursive call...
} else {
// Contains slide identifier?
}

Android app licensing - any current tutorials on this? : I am hoping somebody can point me in the right direction on this one. I have been reading for a few days now on the developer site, various posts on stackoverflow, etc., and am really struggling to piece all of this together. The Google documentation seems to have some gaps, or I'm simply missing the boat. I have attempted to follow the Google docs on this a few times and keep running in to issues.
The most recent is that after going through the steps of downloading the market libraries via the SDK manager and then creating the new library module, I feel I'm missing the piece that will allow my app to see the modules. Specifically, I am guessing there is a dependency that needs to be added to gradle, but I have found no such reference in any of the documentation. If that's not the case, then I have no idea why my imports are not being found.
Certainly this feature must work and work well, so I am hoping somebody can point me to a current/decent tutorial or functional sample application that I can view the code on. I did review the sample application that is part of the sdk and as far as the code within the MainActivity goes, that is all fine and good. My main issue is that I can't seem to get my application to be aware of these libraries to move forward with the implementation of the methods to perform the validation how I need.
Any direction would be greatly appreciated.
Thank you!

(ex: I have 2 lines in my text file containing 2 words each (abc, bcd on the first line and cde, def on the second) annd I want the output to be bcd on the first line and cde and def on the second). I researched this and I only came across to how to remove the first word in all the lines but I only need in the first line. Thanks in advance.

I've got a pen with the whole code on. i'm using ATOM so i've just pulling the objects path and pasting it in the url.
My first website so don't be to harsh please but any critique is welcome.
For some reason i can't set a background image on the body no matter what i try.

Python equivalent of golang's defer statement : <p>How would one implement something that works like the <code>defer</code> statement from go in python? </p>
<p>Defer pushes a function call to a stack. When the function containing the defer statement returns, the defered function calls are popped and executed one by one, in the scope that the defer statement was inside in the first place. Defer statements look like function calls, but are not executed until they are popped.</p>
<p>Go example of how it works:</p>
<pre><code>func main() {
fmt.Println("counting")
var a *int
for i := 0; i < 10; i++ {
a = &i
defer fmt.Println(*a, i)
}
x := 42
a = &x
fmt.Println("done")
}
</code></pre>
<p>Outputs: </p>
<pre><code>counting
done
9 9
8 8
7 7
6 6
5 5
4 4
3 3
2 2
1 1
0 0
</code></pre>
<p>Go example of a usecase:</p>
<pre><code>var m sync.Mutex
func someFunction() {
m.Lock()
defer m.Unlock()
// Whatever you want, with as many return statements as you want, wherever.
// Simply forget that you ever locked a mutex, or that you have to remember to release it again.
}

Difference between Firefox and Firefox developer nowdays - 2017 : <p>When Firefox developer edition introduced, I was so happy, that I can use WebIde, responsive design tool, eyedroper, etc... Today I had enough.</p>
<p>There are a lot of bugs in it, I wont start to enumarate how many bugs sended and approved by me and my colleague... </p>
<p>I've searched for this topic in google, and everywhere I saw, that regular firefox has no WebIde, responsive design view, eyedropper, etc...</p>
<p>I've downloaded the regular firefox, and see no difference. All of these tools are in it, so it seems to me that with aurora channel I get an unstable something what is just impede in my work instead it helps me.</p>
<p>So, my question is: is there any significant difference between the two versions what I did not spot?</p>

Why does std::find_if(first, last, p) not take predicate by reference? : <p>I was looking at the various signatures for <a href="http://en.cppreference.com/w/cpp/algorithm/find" rel="noreferrer"><code>std::find_if</code> on cppreference.com,</a> and I noticed that the flavors that take a predicate function appear to accept it by value:</p>
<pre><code>template< class InputIt, class UnaryPredicate >
InputIt find_if( InputIt first, InputIt last,
UnaryPredicate p );
</code></pre>
<p>If I understand them correctly, lambdas with captured variables allocate storage for either references or copies of their data, and so presumably a "pass-by-value" would imply that the copies of captured data are copied for the call.</p>
<p>On the other hand, for function pointers and other directly addressable things, the performance should be better if the function pointer is passed directly, rather than by reference-to-pointer (pointer-to-pointer). </p>
<p>First, is this correct? Is the <code>UnaryPredicate</code> above going to be a by-value parameter?</p>
<p>Second, is my understanding of passing lambdas correct?</p>
<p>Third, is there a reason for passing by value instead of by reference in this situation? And more to the point, is there not some sufficiently ambiguous syntax (hello, universal reference) that would let the compiler do whatever it wants to get the most performance out?</p>

Is it possible to set custom CPU throttling in Chrome DevTools? : <p>I am using Google Chrome 63.</p>
<p>In DevTools in <strong>Performance</strong> tab there are three CPU throttling settings: "No throttling", "4x slowdown" and "6x slowdown".</p>
<p>Is it possible to set custom throttling, for example "20x slowdown"? It could be via setting some flag in <strong>chrome.exe</strong> file or programmatically via NodeJS library.</p>
<p>I found that Lighthouse library has kind of <a href="https://npmdoc.github.io/node-npmdoc-lighthouse/build/apidoc.html#apidoc.element.lighthouse.emulation.enableCPUThrottling" rel="noreferrer">helpful function</a> but if I change the default value inside it (<strong>CPU_THROTTLE_METRICS</strong> seems to be equal to 4) from 4 to (for example) 20 and run it, how can I be sure it really is 20x slowed down?</p>
<p>Also, I would like to know, if it is possible to do such simulated "slow down" to the GPU in similar way?</p>
<p>Thanks for any advice.</p>

How do I make make/ninja limit parallelism based on memory pressure? : <p>If I use <code>make -j2</code>, it builds fine, but under-utilizes CPU:</p>
<p><a href="https://i.stack.imgur.com/gYhxt.png" rel="noreferrer"><img src="https://i.stack.imgur.com/gYhxt.png" alt="j2"></a></p>
<p>If I use <code>make -j4</code>, it builds fast, but for some particular template-heavy files it consumes a lot of memory, slowing down entire system and build process as well due to swapping out to HDD:</p>
<p><a href="https://i.stack.imgur.com/qKxol.png" rel="noreferrer"><img src="https://i.stack.imgur.com/qKxol.png" alt="j4"></a></p>
<p>How do I make it automatically limit number of parallel tasks based on memory, like this:</p>
<p><a href="https://i.stack.imgur.com/KN4jW.png" rel="noreferrer"><img src="https://i.stack.imgur.com/KN4jW.png" alt="enter image description here"></a></p>
<p>, so that it builds the project at maximum rate, but slows down in some places to avoid hitting memory wall?</p>
<p>Ideas:</p>
<ul>
<li>Use <code>-l</code> and artificially adjust load average if memory is busy (load average grows naturally when system is already in trouble).</li>
<li>Makes memory allocation syscalls (like sbrk(2) or mmap(2)) or page faults keep process hanged until memory gets reclaimed by finished jobs instead of swapping out other processes. Deadlock-prone unfortunately...</li>
</ul>

Passing props as parameter to the onClick event : I am working on a React project. I am having a div in my component. I give a key to this div using uuid.v4() function (generates random number). Now when I click this div, I want to send this key as a parameter to click event. I am not able to solve how to sent the key to the click event when they are of same component. I am trying to do it like this
<div className="img-scroll">
{this.state.imageSearchResults.items.map((item, ind) => {
return <div className="person-image"
key={uuid.v4()}
onClick={()=>{this.onGoogleImageSelect()}}
style={{backgroundImage:`url(${item.link})`}}>
</div>
})}
</div>
click event function
onGoogleImageSelect(e){
console.log(e.target.key)
}
This gives me error
Uncaught TypeError: Cannot read property 'target' of undefined
How can I send that key to the click event?

calculating occurances of values in an input stream : I am a college student who is currently learning programming. one of the problem statements given to us was:
user inputs an integer n followed by n different integers. Without using arrays or strings, find the number which occurs the most number of times in the input stream.
we are required to use the simplecpp package which is basically easier commands than standard c++. for example we write repeat(n) to get a for loop with n iterations.
What can i do to solve the problem?.
I thought of creating a number like 10101010[number]10101010[number2]... to store the input and then splitting but this fails to solve the problem.
we are not allowed to use anything like while loops or string manipulation to solve the problem.the only solutions i could think of were using the string method and then manipulating the string but apparently that is not allowed.
Any method to do this and such other problems where input cannot be stored in an array?

<pre><code>Double current = map.get(foo);
f += current == null ? 0.0 : current;

Is there a proper way of resetting a component's initial data in vuejs? : <p>I have a component with a specific set of starting data:</p>
<pre><code>data: function (){
return {
modalBodyDisplay: 'getUserInput', // possible values: 'getUserInput', 'confirmGeocodedValue'
submitButtonText: 'Lookup', // possible values 'Lookup', 'Yes'
addressToConfirm: null,
bestViewedByTheseBounds: null,
location:{
name: null,
address: null,
position: null
}
}
</code></pre>
<p>This is data for a modal window, so when it shows I want it to start with this data. If the user cancels from the window I want to reset all of the data to this. </p>
<p>I know I can create a method to reset the data and just manually set all of the data properties back to their original:</p>
<pre><code>reset: function (){
this.modalBodyDisplay = 'getUserInput';
this.submitButtonText = 'Lookup';
this.addressToConfirm = null;
this.bestViewedByTheseBounds = null;
this.location = {
name: null,
address: null,
position: null
};
}
</code></pre>
<p>But this seems really sloppy. It means that if I ever make a change to the component's data properties I'll need to make sure I remember to update the reset method's structure. That's not absolutely horrible since it's a small modular component, but it makes the optimization portion of my brain scream. </p>
<p>The solution that I thought would work would be to grab the initial data properties in a <code>ready</code> method and then use that saved data to reset the components:</p>
<pre><code>data: function (){
return {
modalBodyDisplay: 'getUserInput',
submitButtonText: 'Lookup',
addressToConfirm: null,
bestViewedByTheseBounds: null,
location:{
name: null,
address: null,
position: null
},
// new property for holding the initial component configuration
initialDataConfiguration: null
}
},
ready: function (){
// grabbing this here so that we can reset the data when we close the window.
this.initialDataConfiguration = this.$data;
},
methods:{
resetWindow: function (){
// set the data for the component back to the original configuration
this.$data = this.initialDataConfiguration;
}
}
</code></pre>
<p>But the <code>initialDataConfiguration</code> object is changing along with the data (which makes sense because in the read method our <code>initialDataConfiguration</code> is getting the scope of the data function. </p>
<p>Is there a way of grabbing the initial configuration data without inheriting the scope? </p>
<p>Am I overthinking this and there's a better/easier way of doing this? </p>
<p>Is hardcoding the initial data the only option?</p>

Sorting through list and storing different variables : So I'm using pandas to read from a row of data that looks like this:
0 overcast
1 overcast
2 overcast
3 overcast
4 rainy
5 rainy
6 rainy
7 rainy
8 rainy
9 sunny
10 sunny
11 sunny
12 sunny
13 sunny
And I wish to store overcast (first entry) as a variable, and then iterate through the list until there is a contrasting variable, and store that one also. This should assign any other contrasting variables along the way until until the end of the list.
So in this case, I should end up with 3 variables. 0 = overcast, 1 = rainy, 2 = sunny but I want this to work just as well if there are five different conditions in a classifier, not just two or three.
I'm having a hard time figuring out the best way to do this or maybe there is something in pandas that does this for me that I'm missing?

RxJS5 finalize operator not called : <p>I'm trying to trigger a callback when all my observables are executed. In my other, older project i used <code>finally</code> like so and that worked like a charm: </p>
<pre><code>this.myService.callDummy()
.finally(() => console.log('Works!'))
.subscribe(result => ...)
</code></pre>
<p>But now I'm using a newer version of RxJS with <strong>Pipeable operators</strong>, but the <code>finally</code> call (now renamed to <code>finalize</code>) never gets executed. There is little information to be found and I'm not sure what I'm doing wrong.</p>
<pre><code>combineLatest(
this.route.queryParams,
this.myService.callDummy1(),
this.myService.callDummy2()
)
.pipe(finalize(() => console.log('Does not work!')))
.subscribe(results => ...);
</code></pre>
<p>Any help is appreciated.</p>

Finding latest record from duplicates : I have a customers table with ID's and some date/time columns. But those ID's have duplicates and i just want to Analyse distinct values.
I tried using groupby but this makes the process very slow.
Due to data sensitivity can't share it.
Any suggestions would be helpful.

this.name = name;
}
public String getName() {
return name + " Hello";
}
public static void main() {
User u = new User();
u.setName("Yethendra");
}
}
If I try to insert u record into db using hibernate, for name column which is the value that will be inserted?
