changing letters in text in R : I have a text. It includes letters like ş ç ü ö ı. I need to changed them with s c u o i. I wrote following code:
`string <- "ş ç ı ğ ü ö f s x q"
chartr("ş ç ı ğ ü ö", "s c i g u o", string)`
My text file name is `text`. How can apply the code above to my text, since I have still these letters?

Same layout Look different in to device which have same screen size : I have 2 phone amsung s6 edge+ & Samsung note 4, Both have same same screen size 5.7 inch & same screen resolution 1440X2560 & both layout have xxxhdpi density. still same layout look different on both device.
even top status bar & action bar is also look different on both device which is system genereated.
any one can suggest some solution to have same UI on each and every android device.
[Screen shot of same layout in both devices][1]

Speed up expensive IEnumerable<T> operation : <p>I am working on a C# library that recursively enumerates the subfolders of a remote share over the network. This is an expensive operation, and there may be thousands of folders to be traversed. The method that carries out this work for the client returns an <code>IEnumerable<string></code>, and uses lazy evaluation (as is often the case with <code>IEnumerable<T></code>, so the call itself returns very quickly, but then, when the client executes a <code>foreach</code> loop or a <code>Take()</code> call on the return value, things get pretty slow.</p>
<p>I am looking for approaches to speed this up. Some ideas include:</p>
<ol>
<li>Avoid lazy enumeration by making my library retrieve all items and store them in a <code>List<string></code>, for example, before it is returned to the client. This would make the method call much slower, but iteration much faster.</li>
<li>Drop the functionality to enumerate all the subfolders, and require that the client specifies some kind of filter that limits the number of items to traverse.</li>
<li>Use an altogether different method to enumerate folders which avoids <code>IEnumerable<T></code>.</li>
</ol>
<p>I have run out of ideas. What approach would you suggest to make this work, and fast? Thank you.</p>

PEM routines:PEM_read_bio:bad end line : <p>I'm trying to parse the developer certificate in embedded.mobileprovision file. Firstly I use</p>
<p><code>security cms -D -i embedded.mobileprovision</code> </p>
<p>to get the base64 developer certificate string. </p>
<p>Then I split the string every 64 characters and stored in a file named dev.cer. </p>
<p>Finally add <code>-----BEGIN CERTIFICATE-----</code> at the first line and <code>-----END CERTIFICATE-----</code> at the end of file. </p>
<p>On my mac computer, I right click the dev.cer file and the developer informations are all there. However, When I use <code>openssl x509 -in dev.cer -text -noout</code>, error comes out:</p>

Why is grid span not being excepted for "blank1" in IE 11 : css grid issue: Third grid item "blank1" should row span and cover both row 1 and row 2 of column 3. But it is not working in IE 11. It is only covering the first row.
Here is a link to the file online. Look at in in firefox and it will show what it is suppose to look like. IE 11 need fixing.

Why does Google say I need chrome to use my Yubico security key? : <p>Not sure if this is the right place to ask, but here goes.
When I'm trying to sign into google, and it asks for my security key, it says that it can only be used in Chrome. This is a problem because my school only has internet explorer on the computers (bad, I know) and this makes it more annoying to sign in.
Is there a workaround, and does anyone know why this is?</p>
<p>(p.s. I have tried to find some info about this but nothing explains why it needs chrome, especially since when I trigger the key in microsoft word all it does it print some text)</p>

Creating an empty nested list in python : <p>i'm trying to create an empty nested list in python. I have searched for information regarding nested list and most are usually nested lists that already has values in it. </p>
<p>The reason I needed a nested list is because I have a set of items: Apple, Pears and Oranges. However, Each item has another list that consists of: ID, price, quantity. </p>
<p>So what I'm planning is to:
1. Put all items into index 0,1,2 respectively.
So, apple = [0], pears =[1], oranges =[2]
2. Create another nested list to put ID,price and quantity.
So using apple as an example, I would do:
apple[0][0].append(ID), apple[0][1].append(price), apple[0][2].append(quantity)</p>
<p>Is it possible for nested list to work these way? Or is there any other way to create an empty nested list? By the way, the apple, pears and orange all have their own python code file, so I have to import the pears and orange python file into the apple python file. I would appreciate any help given. Thank You.</p>
<p>Codes from apple.py:</p>
<pre><code>fruits = [],[]
fruits[0],[0].append("ID")
fruits[0],[1].append("price")
fruits[0],[2].append("quantity")
</code></pre>
<p>Codes from pears.py:</p>
<pre><code>fruits = [],[]
fruits[1],[0].append("ID")
fruits[1],[1].append("price")
fruits[1],[2].append("quantity")
</code></pre>

How can i use scanf and if with strings (Very basic) : I just had my first class in c programing at college and i did this:
#include <stdio.h>
int main()
{
char answer='x';
printf("Should the crocodile eat the man? y/n ");
scanf("%s",&answer);
printf("%s",& answer);
if(answer == 'y')
{printf("the man is dead");}
if(answer == 'n')
{printf("the man still alive ");}
}
How can i do the same with strings instead of single charactes?
i have tried many things but nothing works.

Connection reset by peer while running Apache Spark Job : <p>We have two HDP cluster's setup let's call them A and B. </p>
<p><strong>CLUSTER A NODES</strong> : </p>
<ul>
<li>It contains a total of 20 commodity machines.</li>
<li>There are 20 data nodes.</li>
<li>As namenode HA is configured, there is one active and one standby namenode.</li>
</ul>
<p><strong>CLUSTER B NODES</strong> : </p>
<ul>
<li>It contains a total of 5 commodity machines.</li>
<li>There are 5 datanodes.</li>
<li>There is no HA configured and this cluster has one primary and one secondary namenode.</li>
</ul>
<p>We have three major components in our application that perform an ETL (Extract, Transform and Load) operation on incoming files. I will refer to these components as E,T and L respectively.</p>
<p><strong>COMPONENT E CHARACTERISTICS</strong> : </p>
<ul>
<li>This component is an Apache Spark Job and it runs solely on Cluster B. </li>
<li>It's job is to pick up files from a NAS storage and put them into HDFS in cluster B.</li>
</ul>
<p><strong>COMPONENT T CHARACTERISTICS</strong> : </p>
<ul>
<li>This component is also an Apache Spark Job and it runs on Cluster B.</li>
<li>It's job is to pick up the files in HDFS written by component E, transform them and then write the transformed files to HDFS in cluster A.</li>
</ul>
<p><strong>COMPONENT L CHARACTERISTICS</strong> :</p>
<ul>
<li>This component is also an Apache Spark job and it runs solely on Cluster A.</li>
<li>It's job is to pick up files written by Component T and load the data to Hive tables present in Cluster A.</li>
</ul>
<p>Component L is the gem among all of the three components and we have not faced any glitches in it. There were minor unexplained glitches in component E, but component T is the most troublesome one.</p>
<p>Component E and T both make use of DFS client to communicate to the namenode.</p>
<p>Following is an excerpt of the exception that we have observed intermittently while running component T : </p>

<p>As mentioned, we face this exception very intermittently and when it does occur our application gets stuck causing us to restart it.</p>
<p><strong>SOLUTIONS THAT WE TRIED :</strong></p>
<ul>
<li><p>Our first suspect was that we are overloading the active namenode in cluster A since component T does open a lot of DFS client in parallel and performs file operations on different files ( no issue of contention on same files ). In our effort to tackle this problem, we looked at two key parameters for the namenode <strong>dfs.namenode.handler.count</strong> and <strong>ipc.server.listen.queue.size</strong> and bumped the latter from 128 (default) to 1024.</p></li>
<li><p>Unfortunately, the issue still persisted in component T. We started taking a different approach on the problem. We focused solely on finding the reason for the occurrence of Connection Reset By Peer. According to a lot of articles and stack exchange discussions, the problem is described as follows, <em>the <strong>RST</strong> flag has been set by the peer which results in an immediate termination of the connection</em>. In our case we identified that the peer was the namenode of cluster A. </p></li>
<li><p>Keeping the RST flag in mind, I delved deep into understanding the internals of TCP communication only w.r.t. the reason of RST flag. </p></li>
<li>Every socket in Linux distributions ( not BSD ) has two queue's associated with it namely, the accept and the backlog queue. </li>
<li>During the TCP handshake process, all requests are kept in the backlog queue until ACK packets are received from the node that started to establish the connection. Once received, the request is transferred to the accept queue and the application that opened the socket can start receiving packets from the remote client.</li>
<li>The size of the backlog queue is controlled by two kernel level parameters namely <strong>net.ipv4.tcp_max_syn_backlog</strong> and <strong>net.core.somaxconn</strong> whereas the application ( namenode in our case ) can request the kernel for queue size that it desires limited by an upper bound ( we believe the accept queue size is the queue size defined by <strong>ipc.server.listen.queue.size</strong> ).</li>
<li>Also, another interesting thing to note here is that if the size of <strong>net.ipv4.tcp_max_syn_backlog</strong> is greater than <strong>net.core.somaxconn</strong>, then the value of the former is truncated to that of the latter. This claim is based upon Linux documentation and can be found at <a href="https://linux.die.net/man/2/listen" rel="noreferrer">https://linux.die.net/man/2/listen</a>.</li>
<li><p>Coming back to the point, when the backlog fills up completely TCP behaves in two manners and this behaviour can also be controlled by a kernel parameter called <strong>net.ipv4.tcp_abort_on_overflow</strong>. This is by default set to 0 and causes kernel to drop any new SYN packets when the backlog is full, which in turn lets the sender resend SYN packets. When set to 1, the kernel will mark the RST flag in a packet and send it to the sender thus abruptly terminating the connection. </p></li>
<li><p>We checked the value of the above mentioned kernel parameters and found out that <strong>net.core.somaxconn</strong> is set to 1024, <strong>net.ipv4.tcp_abort_on_overflow</strong> is set to 0 and <strong>net.ipv4.tcp_max_syn_backlog</strong> is set to 4096 across all the machines in both the clusters. </p></li>
<li><p>The only suspect that we have left now are the switches that connect Cluster A to Cluster B because none of the machines in any of the cluster will ever set the RST flag as the parameter <strong>net.ipv4.tcp_abort_on_overflow</strong> is set to 0. </p></li>
</ul>
<p><strong>MY QUESTIONS</strong></p>
<ul>
<li>It is evident from HDFS documentation that DFS Client uses RPC to communicate with the namenode for performing file operations. Does every RPC call involves the establishment of a TCP connection to namenode?</li>
<li>Does the parameter <strong>ipc.server.listen.queue.size</strong> define the length of accept queue of the socket at which namenode accepts RPC requests?</li>
<li>Can the namenode implicitly close connections to DFS client when under heavy load thus making the kernel to send a packet with RST flag being set, even if the kernel parameter <strong>net.ipv4.tcp_abort_on_overflow</strong> is set to 0?</li>
<li>Are L2 or L3 switches ( used for connecting the machines in our two clusters ) capable of setting the RST flag because they are not able to handle bursty traffics? </li>
</ul>
<p>Our next approach to this problem is to identify which machine or switch ( there is no router involved ) is setting the RST flag by analyzing the packets using tcpdump or wireshark. We will also bump the size of all the queues mentioned above to 4096 in order to effectively handle bursty traffic.</p>
<p>The namenode logs show no sign of any exceptions except that the Namenode Connection Load as seen in Ambari peeked at certain points in time and not necessarily when the Connection Reset By Peer exception occured. </p>
<p>To conclude, I wanted to know whether or not we are headed on the right track to solve this problem or are we just going hit a dead end?</p>
<p><strong>P.S.</strong> I apologize for the content's length in my question. I wanted to present the entire context to the readers before asking for any help or suggestions. Thank you for your patience. </p>

<p>That works absolutely fine, but it returns the date as <code>06/01/2016</code> but I want it returned as <code>06-01-2016</code> but I can't seem to find out how to do it correctly.</p>

Pass parameters to Airflow Experimental REST api when creating dag run : <p>Looks like Airflow has an experimental REST api that allow users to create dag runs with https POST request. This is awesome. </p>
<p>Is there a way to pass parameters via HTTP to the create dag run? Judging from the official docs, found <a href="https://airflow.apache.org/api.html" rel="noreferrer">here</a>, it would seem the answer is "no" but I'm hoping I'm wrong. </p>

Change the format of the returned data when selecting records. Flask : <p>In my flask application, in routes.py I get entries with specific fields of the <code>Location</code> model:</p>
<pre><code>...
location = db.session.query(Location.id, Location.name,Location.code, Location.id_parent).all()
newLocat = list( location)
print(str(newLocat))
...
</code></pre>
<p>The format of the returned data is as follows:</p>
<pre><code>[(1, 'Test1', 101, 0), (2, 'Test2', 202, 1)]
</code></pre>
<p>How to make the returned data format look like this?</p>
<pre><code>[{'id': '1', 'name': 'Test1','code':101, 'id_parent': '0'}, {'id': '2', 'name': 'Test2','code':202, 'id_parent': '1'}]

Can't we do node creation using pointer to object in C++? : I was solving this problem on Linked List on hacker rank : https://www.hackerrank.com/challenges/insert-a-node-at-the-head-of-a-linked-list/
And got correct answer for the given code . Most of the code was prewritten ; I only had to complete the function insertNodeAtHead function (enclosed between the three stars) :
#include <bits/stdc++.h>
using namespace std;
class SinglyLinkedListNode {
public:
int data;
SinglyLinkedListNode *next;
SinglyLinkedListNode(int node_data) {
this->data = node_data;
this->next = nullptr;
}
};
class SinglyLinkedList {
public:
SinglyLinkedListNode *head;
SinglyLinkedListNode *tail;
SinglyLinkedList() {
this->head = nullptr;
this->tail = nullptr;
}
};
void print_singly_linked_list(SinglyLinkedListNode* node, string sep, ofstream& fout) {
while (node) {
fout << node->data;
node = node->next;
if (node) {
fout << sep;
}
}
}
void free_singly_linked_list(SinglyLinkedListNode* node) {
while (node) {
SinglyLinkedListNode* temp = node;
node = node->next;
free(temp);
}
}
// Complete the insertNodeAtHead function below.
/*
* For your reference:
*
* SinglyLinkedListNode {
* int data;
* SinglyLinkedListNode* next;
* };
*
*/
***SinglyLinkedListNode* insertNodeAtHead(SinglyLinkedListNode* llist, int data) {
SinglyLinkedListNode *nnode;
nnode = new SinglyLinkedListNode(data);
if(llist !=NULL)
nnode->next=llist;
return llist=nnode;
}***
int main()
{
ofstream fout(getenv("OUTPUT_PATH"));
SinglyLinkedList* llist = new SinglyLinkedList();
int llist_count;
cin >> llist_count;
cin.ignore(numeric_limits<streamsize>::max(), '\n');
for (int i = 0; i < llist_count; i++) {
int llist_item;
cin >> llist_item;
cin.ignore(numeric_limits<streamsize>::max(), '\n');
SinglyLinkedListNode* llist_head = insertNodeAtHead(llist->head, llist_item);
llist->head = llist_head;
}
print_singly_linked_list(llist->head, "\n", fout);
fout << "\n";
free_singly_linked_list(llist->head);
fout.close();
return 0;
}
I had to complete the insertNodeAtHead() function only . Rest all was already there. But when I tried to do it without using pointer nnode object( my identifier) of SinglyLinkedListNode class type(their predefined class) I get compilation error:
#include <bits/stdc++.h>
using namespace std;

this - > next = nullptr;
}
};
class SinglyLinkedList {
public:
SinglyLinkedListNode * head;
SinglyLinkedListNode * tail;
SinglyLinkedList() {
this - > head = nullptr;
this - > tail = nullptr;
}
};
void print_singly_linked_list(SinglyLinkedListNode * node, string sep, ofstream & fout) {
while (node) {
fout << node - > data;
node = node - > next;
if (node) {
fout << sep;
}
}
}
void free_singly_linked_list(SinglyLinkedListNode * node) {
while (node) {
SinglyLinkedListNode * temp = node;
node = node - > next;
free(temp);
}
}
// Complete the insertNodeAtHead function below.
/*

*
* SinglyLinkedListNode {

***SinglyLinkedListNode * insertNodeAtHead(SinglyLinkedListNode * llist, int data) {
SinglyLinkedListNode nnode;
nnode = new SinglyLinkedListNode(data);
if (llist != NULL)
nnode.next = llist;
return llist = & nnode;
}***
int main() {
ofstream fout(getenv("OUTPUT_PATH"));
SinglyLinkedList * llist = new SinglyLinkedList();
int llist_count;
cin >> llist_count;
cin.ignore(numeric_limits < streamsize > ::max(), '\n');
for (int i = 0; i < llist_count; i++) {
int llist_item;
cin >> llist_item;
cin.ignore(numeric_limits < streamsize > ::max(), '\n');
SinglyLinkedListNode * llist_head = insertNodeAtHead(llist - > head, llist_item);
llist - > head = llist_head;
}
print_singly_linked_list(llist - > head, "\n", fout);
fout << "\n";
free_singly_linked_list(llist - > head);
fout.close();
return 0;

***I firmly believed that it should have worked but it didn't happen so. Since the logic was same , the only difference was I used pointer to create the object.***
Since I am new to C++ I am unable to figure out why is this happening. Please give an insight.

merge sort infinite recursion : I'm learning Ruby and algorithms at the current moment an would like some guidance in solving this issue that has arise. I haven't started the merge process yet. So far I've only focused on dividing the array over and over again until only 1 number is left in the array. Below is my code showing how I implemented this so far. My problem is the loop will not break and I'm unsure why. I'm hoping someone can point me in the right direction as to what I'm missing. I'm also open to resources to help me solve this problem better.
def mergesort(list)
mid = list.length / 2
left = list[0, mid]
right = list[mid, list.size]
until left.size <= 1 || right.size <= 1 do
test(mergesort(left), mergesort(right))
end
print left
print right
def test(left, right)
sorted = []
left.length / 2
right.length / 2
# print sorted
end

How can I update ASP.NET Core app over an existing/running site without stopping the web server? : <p>We have an ASP.NET Core site running on our test server that we would like to auto-deploy by XCopy to our IIS web server as we do our current apps, where I already have the site running. I've added a publish profile that packages the site to a "publish-local" directory within the solution. Whenever I try to copy over the existing site, all DLLs are being used by another process, presumably Kestrel, so I am forced to deploy to a sibling directory and re-map IIS to look at the sibling. How does one update a running ASP.NET Core site without having to manually intervene and stop either the Kestrel or IIS web servers?</p>

what method does the computer use to add unsigned integers : int main(){
unsigned int num1;
unsigned int num2;
unsigned int sum = num1 + num2;
cout << hex << sum;
}
If i have two unsigned integers say num1 and num2.
And then I tell the computer to unsigned int sum = num1 + num2;
What method does the computer use to add them, would it be two's complement. Would the sum variable be printed in two's complement.

pairwise adding element in a list : I have two list of tuples
[1,3000],[2,5000],[3,7000],[4,10000]
[1,2000],[2,3000],[3,4000],[4,5000]]
the sum is 10000. Here we have [2,5000],[4,5000] and [3,7000],[2,3000] so the output should be **[2,4]** and **[3,2]**
[[1,2000],[2,4000],[3,6000]]
[[1,2000]]
the sum is 7000. Here since I dont have a combination that sum up to 7000 I consider all the possible combinations 4000(2000+2000),6000(4000+2000) and 8000(6000+2000) and consider the next lowest number from the desired sum which is 6000 . For 6000 my output should be [2,4000] and [1,2000] which is **[2,1]**
Here is my code
import itertools
def optimalUtilization(maximumOperatingTravelDistance,
forwardShippingRouteList, returnShippingRouteList):
result=[]
t1=[]
t2=[]
for miles in forwardShippingRouteList:
t1.append(miles[1])
for miles in returnShippingRouteList:
t2.append(miles[1])
result.append(t1)
result.append(t2)
total_sum=set()
for element in list(itertools.product(*result)):
if sum(element)<=maximumOperatingTravelDistance:
total_sum.add(sum(element))
total_sum=sorted(total_sum,reverse=True)

result=[]
for carid,miles in returnShippingRouteList:
if (maximumOperatingTravelDistance-miles) in dist_dict:
result.append(list((dist_dict[maximumOperatingTravelDistance-miles],carid)))
return result

Apply CSS to all but last element? : <p>I've got the following html:</p>
<pre><code><ul class="menu">
<li><a>list item 1</a></li>
<li><a>list item 2</a></li>
...
<li><a>list item 5</a></li>
</ul>
</code></pre>
<p>I want to apply a border to all the <code><a></code> elements except the last one. </p>
<p>I've been trying this:</p>
<pre><code>.menu a {
border-right: 1px dotted #ccc;
}
.menu a:last-of-type {
border-right: none;
}
</code></pre>
<p>but I end up with a border on none of the elements, I guess because the <code><a></code> in each case is the last of type. </p>
<p>How can I do this? I'd prefer to use only CSS if possible, and I'd like IE9 compatibility if possible. </p>

Android Button: get value? I do not mean the text : I have an android button with a text. When the button is clicked, I want to access the database for which I need an integer associated with the button. I do not mean the text of the button which is visible to the user (i.e. not the string "Save data"). I mean something like the value of the button, which could be an integer (e.g. 17). I am reading [this](https://developer.android.com/reference/android/widget/TextView) since button extends textview. I've scanned the XML attributes but I cannot find anything, does a button in android not have a value that I can fetch in my activity method which is linked to the button? I was thinking about something like casting the View that I get in my activity method to a `(Button)` and then call something like `int my_database_int = button.getValue()` but I do not find anything in the link above and I find it hard to believe that there is no such functionality?

How to avoid overlapping OnClicks? : I'm using a Relative Layout where I've placed a Button over an Image View as shown [here][1].
<br />
The problem is I've used `OnClick` on both button and Image View that refers to different methods i.e., button when clicked calls a method, Image when clicked calls a different method. When I click on the button the App force quits i.e., has a Runtime Exception.
**activity_main.xml**:
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="click"
android:onClick="sampleClick"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="125dp"
android:id="@+id/button" />
<ImageView
android:id="@+id/imageView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:srcCompat="@drawable/oreo"
android:onClick="imageClick"
android:layout_alignParentTop="true"
android:layout_alignParentStart="true" />
**MainActivity.java**:
public void sampleClick(View view){
Toast.makeText(MainActivity.this,"Button Click",Toast.LENGTH_LONG).show();
}
public void imageClick(View view){
Toast.makeText(MainActivity.this,"Image Click",Toast.LENGTH_LONG).show();
}
Help me solve the Error.

JavaFX or Swing in a new project : <p>Well, i have 180 days to construct a new project, where i should use the TOP tecnologies (Java 8, Hibernate 5 and more ..)</p>
<p>I have a big doubt before start it: What GUI Framework should i use ?</p>
<p>If i should use Swing (as i always did) or start this project with JavaFX ( i don't have any knowledge about it). </p>
<p>So, i'm thinking about some things:</p>
<p>1) If i start with JavaFX, the difference will be very big to customer ?
2) If i start with JavaFX, in 180 days i will have enought time to study about this tecnology ? Is very complex or different from Swing?</p>

C++ Simulate key press and mantain it pressed on Windows : I Have this C++ Function that receives Virtual Key and Press/Release the key:
void SendKey (WORD wVk, bool press) {
keybd_event(wVk, 0, press? 0 : KEYEVENTF_KEYUP, 0);
}
But it does just press the key 1 time, not constantly as i expected.
Im constructing a joypad simulation, so, i need to configure KeyDown and KeyUp respectively, this is a little C++ process that reads by cmd the key and the type (Down, Press or Release):
#define WINVER 0x0500
#include <windows.h>
#include <iostream>
using namespace std;
void SendKey (WORD wVk, bool press) {
keybd_event(wVk, 0, press? 0 : KEYEVENTF_KEYUP, 0);
}
void PressKey (WORD wVk) {
SendKey(wVk, true);
Sleep(30);
SendKey(wVk, false);
}
int main() {
int key;
char type;
while(true) {
cin >> key;
cin >> type;
if(key == 0) break;
if(type == 'd') SendKey((WORD) key, true);
if(type == 'r') SendKey((WORD) key, false);
if(type == 'p') PressKey((WORD) key);
}
return 0;
}
Thanks a lot, if anyone have built something like this, plz tell me.

Acess phone camera with a button (HTML) : I'm developing a application that needs to acess the phone camera. I'm currently using the Ratchet Framework but that's not really relevant here.
I have a button that needs to open the camera onCLick. I know that to acess the camera we need this:
<input type="file" accept="image/*" onchange="updatePhoto(event);"></input>
And my button is like this:
<button class="btn btn-positive btn-block"> Choose photo </button>
I tried putting the input to acess the camera inside the button but it doesn't make the ugly "Choose photo" disapear making it look silly. I just need to replace the standard "Choose photo" that appears when we put only the first input and replace it with the button to look better.

switch two <a> tag elements on the nav in the DOM wth event listeners : <p>Right now i am working on trying to swap the order of tags on a menu so that they still maintain there event listeners and change order on the front end. For example, </p>
<pre><code> <a id = "A" href = ""></a>
<a id = "B" href = ""></a>
<a id = "C" href = ""></a>
<a id = "D" href = ""></a>
</code></pre>
<p>Swap A, B, C, D to any position and at the same time switch them on the front end to represent the same order.
Ive tried many different functions like append(), next(), however none work in a way that consistent. </p>

Flutter: Minimum height on horizontal list view : <p>I'm trying to create a horizontal scrolling list of items in Flutter, and I want that list to only take up the necessary height based on its children. By design “<code>ListView</code> tries to expand to fit the space available in its cross-direction” (from the <a href="https://flutter.io/layout" rel="noreferrer">Flutter docs</a>), which I also notice in that it takes up the whole height of the viewport, but is there a way to make it not do this? Ideally something similar to this (which obviously doesn't work):</p>
<pre class="lang-dart prettyprint-override"><code>new ListView(
scrollDirection: Axis.horizontal,
crossAxisSize: CrossAxisSize.min,
children: <Widget>[
new ListItem(),
new ListItem(),
// ...
],
);
</code></pre>
<hr>
<p>I realize that one way to do this is by wrapping the <code>ListView</code> in a <code>Container</code> with a fixed height. However, I don't necessarily know the height of the items:</p>
<pre class="lang-dart prettyprint-override"><code>new Container(
height: 97.0,
child: new ListView(
scrollDirection: Axis.horizontal,
children: <Widget>[
new ListItem(),
new ListItem(),
// ...
],
),
);
</code></pre>
<hr>
<p>I was able to hack together a “solution” by nesting a <code>Row</code> in a <code>SingleChildScrollView</code> in a <code>Column</code> with a <code>mainAxisSize: MainAxisSize.min</code>. However, this doesn't feel like a solution, to me:</p>
<pre class="lang-dart prettyprint-override"><code>new Column(
mainAxisSize: MainAxisSize.min,
children: <Widget>[
new SingleChildScrollView(
scrollDirection: Axis.horizontal,
child: new Row(
children: <Widget>[
new ListItem(),
new ListItem(),
// ...
],
),
),
],
);
</code></pre>
