I had this error when running my application with Eclipse CDT on Linux x86.
To fix this:

1. In Eclipse:

   Run as -> Run configurations -> Environment

2. Set the path

   LD_LIBRARY_PATH=/my_lib_directory_path
   

Have been fighting this all morning and now have it solved and why it happened. Posting with the hope it helps others

I installed the Krypton.Toolkit which added the tools to the Visual studio toolbox automatically. I then added the tools to the designer, which automatically added the dll to the projrect references, however the toolkit was marked as CopyLocal=false

I built an installer, using all dlls in the release build folder (of course the above dll wasn't there).

Setting copylocal=true, then rebuilding the installer, everything worked fine.

• Make sure the file exists: use os.listdir() to see the list of files in the current working directory
• Make sure you're in the directory you think you're in with os.getcwd() (if you launch your code from an IDE, you may well be in a different directory)
• You can then either:
  • Call os.chdir(dir), dir being the folder where the file is located, then open the file with just its name like you were doing.
  • Specify an absolute path to the file in your open call.
• Remember to use a raw string if your path uses backslashes, like so: dir = r'C:\Python32'
  • If you don't use raw-string, you have to escape every backslash: 'C:\\User\\Bob\\...'
  • Forward-slashes also work on Windows 'C:/Python32' and do not need to be escaped.

Let me clarify how Python finds files:

• An absolute path is a path that starts with your computer's root directory, for example 'C:\Python\scripts..' if you're on Windows.
• A relative path is a path that does not start with your computer's root directory, and is instead relative to something called the working directory. You can view Python's current working directory by calling os.getcwd().

If you try to do open('sortedLists.yaml'), Python will see that you are passing it a relative path, so it will search for the file inside the current working directory. Calling os.chdir will change the current working directory.

Example: Let's say file.txt is found in C:\Folder.

To open it, you can do:

os.chdir(r'C:\Folder')
open('file.txt') #relative path, looks inside the current working directory

or

open(r'C:\Folder\file.txt') #full path

try block should be around open. Not around prompt.

while True:
    prompt = input("\n Hello to Sudoku valitator,"
    "\n \n Please type in the path to your file and press 'Enter': ")
    try:
        sudoku = open(prompt, 'r').readlines()
    except FileNotFoundError:
        print("Wrong file or file path")
    else:
        break

You should read collections framework tutorial first of all.

But to answer your question this is how you should do it:

ArrayList<String> strings = new ArrayList<String>();
strings.add("String1");
strings.add("String2");

// To access a specific element:
System.out.println(strings.get(1));
// To loop through and print all of the elements:
for (String element : strings) {
    System.out.println(element);
}

In Java:

    String regex = "[^-\\s]";

    System.out.println("-".matches(regex)); // prints "false"
    System.out.println(" ".matches(regex)); // prints "false"
    System.out.println("+".matches(regex)); // prints "true"

The regex [^-\s] works as expected. [^\s-] also works.

    The hyphen can be included right after the opening bracket, or right before the closing bracket, or right after the negating caret.

Simple answer if your background allows, why not set background-size: to something just covering device width with media queries and use alongside the :after position: fixed; hack here.

IE: background-size: 901px; for any screens <900px? Not perfect or responsive but worked a charm for me on mobile <480px as i'm using an abstract BG.

As I wrote in the edits of the op, to edit existing excel documents you must use the xlutils module (Thanks Oliver)

Here is the proper way to do it:

#xlrd, xlutils and xlwt modules need to be installed.  
#Can be done via pip install <module>
from xlrd import open_workbook
from xlutils.copy import copy

rb = open_workbook("names.xls")
wb = copy(rb)

s = wb.get_sheet(0)
s.write(0,0,'A1')
wb.save('names.xls')

This replaces the contents of the cell located at a1 in the first sheet of "names.xls" with the text "a1", and then saves the document.

According to Android docs you can use app:useSimpleSummaryProvider="true" in ListPreference and EditTextPreference components.

There's no extra IL code for the var keyword: the resulting IL should be identical for non-anonymous types. If the compiler can't create that IL because it can't figure out what type you intended to use, you'll get a compiler error.

The only trick is that var will infer an exact type where you may have chosen an Interface or parent type if you were to set the type manually.

Update 8 Years Later

I need to update this as my understanding has changed. I now believe it may be possible for var to affect performance in the situation where a method returns an interface, but you would have used an exact type. For example, if you have this method:

IList<int> Foo()
{
    return Enumerable.Range(0,10).ToList();
}

Consider these three lines of code to call the method:

List<int> bar1 = Foo();
IList<int> bar = Foo();
var bar3 = Foo();

All three compile and execute as expected. However, the first two lines are not exactly the same, and the third line will match the second, rather than the first. Because the signature of Foo() is to return an IList<int>, that is how the compiler will build the bar3 variable.

From a performance standpoint, mostly you won't notice. However, there are situations where the performance of the third line may not be quite as fast as the performance of the first. As you continue to use the bar3 variable, the compiler may not be able to dispatch method calls the same way.

Note that it's possible (likely even) the jitter will be able to erase this difference, but it's not guaranteed. Generally, you should still consider var to be a non-factor in terms of performance. It's certainly not at all like using a dynamic variable. But to say it never makes a difference at all may be overstating it.

There are quite a few available.

Can't load library: /home/tom/.swt/lib/linux/x86_64/libswt-gtk-3740.so
Can't load library: /home/tom/.swt/lib/linux/x86_64/libswt-gtk.so

looks like the libraries should be at .swt/lib/linux/x86_64/ if there are not there you can try this command:

locate  libswt-gtk.so

this should find the libraries copy the entire directory to /home/tom/.swt/lib/linux/x86_64

Full code that shows now and 10 minutes added.....

$nowtime = date("Y-m-d H:i:s");
echo $nowtime;
$date = date('Y-m-d H:i:s', strtotime($nowtime . ' + 10 minute'));
echo "<br>".$date;

Take advantage of as.matrix:

# keep the first column 
names <-  df.aree[,1]

# Transpose everything other than the first column
df.aree.T <- as.data.frame(as.matrix(t(df.aree[,-1])))

# Assign first column as the column names of the transposed dataframe
colnames(df.aree.T) <- names

Here is a simple if/else check in underscore.js, if you need to include a null check.

<div class="editor-label">
    <label>First Name : </label>
</div>
<div class="editor-field">
    <% if(FirstName == null) { %>
        <input type="text" id="txtFirstName" value="" />
    <% } else { %>
        <input type="text" id="txtFirstName" value="<%=FirstName%>" />
    <% } %>
</div>

Yes, there is definitely a way to format numbers properly in javascript, for example:

var val=2489.8237

val.toFixed(3) //returns 2489.824 (round up)
val.toFixed(2) //returns 2489.82
val.toFixed(7) //returns 2489.8237000 (padding)

With the use of variablename.toFixed .

And there is another function toPrecision() . For more detail you also can visit

Historically a \n was used to move the carriage down, while the \r was used to move the carriage back to the left side of the page.

for i in *.xls ; do 
  [[ -f "$i" ]] || continue
  xls2csv "$i" "${i%.xls}.csv"
done

The first line in the do checks if the "matching" file really exists, because in case nothing matches in your for, the do will be executed with "*.xls" as $i. This could be horrible for your xls2csv.

I use this for cleaning up data in test/development databases. You can filter by table name and record count.

DECLARE @sqlCommand VARCHAR(3000);
DECLARE @tableList TABLE(Value NVARCHAR(128));
DECLARE @TableName VARCHAR(128);
DECLARE @RecordCount INT;

-- get a cursor with a list of table names and their record counts
DECLARE MyCursor CURSOR FAST_FORWARD
FOR SELECT t.name TableName,
           i.rows Records
    FROM sysobjects t,
         sysindexes i
    WHERE 
          t.xtype = 'U'              -- only User tables
          AND i.id = t.id          
          AND i.indid IN(0, 1)       -- 0=Heap, 1=Clustered Index
          AND i.rows < 10            -- Filter by number of records in the table
          AND t.name LIKE 'Test_%';  -- Filter tables by name. You could also provide a list:
                                     -- AND t.name IN ('MyTable1', 'MyTable2', 'MyTable3');
                                     -- or a list of tables to exclude:
                                     -- AND t.name NOT IN ('MySpecialTable', ... );

OPEN MyCursor;

FETCH NEXT FROM MyCursor INTO @TableName, @RecordCount;

-- for each table name in the cursor, delete all records from that table:
WHILE @@FETCH_STATUS = 0
    BEGIN
        SET @sqlCommand = 'DELETE FROM ' + @TableName;
        EXEC (@sqlCommand);
        FETCH NEXT FROM MyCursor INTO @TableName, @RecordCount;
    END;

CLOSE MyCursor;
DEALLOCATE MyCursor;

And there is another possibility (not in this case) when working with ajax(XMLhttpRequest), while sending information back to the client end you should use res.send(responsetext) instead of res.end(responsetext)

Assuming you also want to check if the item is not null

if (array.Length > 25 && array[25] != null)
{
    //it exists
}

Since no one mentioned, here is another one: Feign, which is used by Spring Cloud.

By setting startDate: new Date()

$('.date-picker').datepicker({
    defaultDate: "+1w",
    changeMonth: true,
    numberOfMonths: 1,
    ...
    startDate: new Date(),
});

if the tuples are unique then this can work

>>> a = [(1, u'abc'), (2, u'def')]
>>> a
[(1, u'abc'), (2, u'def')]
>>> dict(a).keys()
[1, 2]
>>> dict(a).values()
[u'abc', u'def']
>>> 

Perhaps use plt.annotate:

import numpy as np
import matplotlib.pyplot as plt

N = 10
data = np.random.random((N, 4))
labels = ['point{0}'.format(i) for i in range(N)]

plt.subplots_adjust(bottom = 0.1)
plt.scatter(
    data[:, 0], data[:, 1], marker='o', c=data[:, 2], s=data[:, 3] * 1500,
    cmap=plt.get_cmap('Spectral'))

for label, x, y in zip(labels, data[:, 0], data[:, 1]):
    plt.annotate(
        label,
        xy=(x, y), xytext=(-20, 20),
        textcoords='offset points', ha='right', va='bottom',
        bbox=dict(boxstyle='round,pad=0.5', fc='yellow', alpha=0.5),
        arrowprops=dict(arrowstyle = '->', connectionstyle='arc3,rad=0'))

plt.show()

If you need n % m then:

int i = (n < 0) ? (m - (abs(n) % m) ) %m : (n % m);

mathematical explanation:

n = -1 * abs(n)
-> n % m = (-1 * abs(n) ) % m
-> (-1 * (abs(n) % m) ) % m
-> m - (abs(n) % m))

A much easier solution would be to just the split the string based on the character you're matching it with.

For instance,

int getOccurences(String characters, String string) { String[] words = string.split(characters); return words.length - 1; }

This will return 4 in the case of: getOccurences("o", "something about a quick brown fox");

.any() and .all() are great for the extreme cases, but not when you're looking for a specific number of null values. Here's an extremely simple way to do what I believe you're asking. It's pretty verbose, but functional.

import pandas as pd
import numpy as np

# Some test data frame
df = pd.DataFrame({'num_legs':          [2, 4,      np.nan, 0, np.nan],
                   'num_wings':         [2, 0,      np.nan, 0, 9],
                   'num_specimen_seen': [10, np.nan, 1,     8, np.nan]})

# Helper : Gets NaNs for some row
def row_nan_sums(df):
    sums = []
    for row in df.values:
        sum = 0
        for el in row:
            if el != el: # np.nan is never equal to itself. This is "hacky", but complete.
                sum+=1
        sums.append(sum)
    return sums

# Returns a list of indices for rows with k+ NaNs
def query_k_plus_sums(df, k):
    sums = row_nan_sums(df)
    indices = []
    i = 0
    for sum in sums:
        if (sum >= k):
            indices.append(i)
        i += 1
    return indices

# test
print(df)
print(query_k_plus_sums(df, 2))

Output

   num_legs  num_wings  num_specimen_seen
0       2.0        2.0               10.0
1       4.0        0.0                NaN
2       NaN        NaN                1.0
3       0.0        0.0                8.0
4       NaN        9.0                NaN
[2, 4]

Then, if you're like me and want to clear those rows out, you just write this:

# drop the rows from the data frame
df.drop(query_k_plus_sums(df, 2),inplace=True)
# Reshuffle up data (if you don't do this, the indices won't reset)
df = df.sample(frac=1).reset_index(drop=True)
# print data frame
print(df)

Output:

   num_legs  num_wings  num_specimen_seen
0       4.0        0.0                NaN
1       0.0        0.0                8.0
2       2.0        2.0               10.0

I had the same issue. For me I noticed that the https is using another Certificate which was invalid in terms of expiration date. Not sure why it happened. I changed the Https port number and a new self signed cert. WCFtestClinet could connect to the server via HTTPS!

Starting from the decoded base64 data of an OpenSSL rsa-ssh Key, i've been able to guess a format:

• 00 00 00 07: four byte length prefix (7 bytes)
• 73 73 68 2d 72 73 61: "ssh-rsa"
• 00 00 00 01: four byte length prefix (1 byte)
• 25: RSA Exponent (e): 25
• 00 00 01 00: four byte length prefix (256 bytes)

• RSA Modulus (n):

The closest validation of my theory i can find it from RFC 4253:

The "ssh-rsa" key format has the following specific encoding:

  string    "ssh-rsa"
  mpint     e
  mpint     n

Here the 'e' and 'n' parameters form the signature key blob.

But it doesn't explain the length prefixes.

Taking the random RSA PUBLIC KEY i found (in the question), and decoding the base64 into hex:

From RFC3447 - Public-Key Cryptography Standards (PKCS) #1: RSA Cryptography Specifications Version 2.1:

A.1.1 RSA public key syntax

An RSA public key should be represented with the ASN.1 type RSAPublicKey:

  RSAPublicKey ::= SEQUENCE {
     modulus           INTEGER,  -- n
     publicExponent    INTEGER   -- e
  }

The fields of type RSAPublicKey have the following meanings:

• modulus is the RSA modulus n.
• publicExponent is the RSA public exponent e.

Using Microsoft's excellent (and the only real) ASN.1 documentation:

30 82 01 0a       ;SEQUENCE (0x010A bytes: 266 bytes)
|  02 82 01 01    ;INTEGER  (0x0101 bytes: 257 bytes)

giving the public key modulus and exponent:

• modulus = 0xfb1199ff0733f6e805a4fd3b36ca68...837a63
• exponent = 65,537

Update: My expanded form of this answer in another question

I just wrote a simple script to collect the dependencies in ./node_modules. It fulfills my requirement at the moment. This may help some others, I post it here.

var fs = require("fs");

function main() {
  fs.readdir("./node_modules", function (err, dirs) {
    if (err) {
      console.log(err);
      return;
    }
    dirs.forEach(function(dir){
      if (dir.indexOf(".") !== 0) {
        var packageJsonFile = "./node_modules/" + dir + "/package.json";
        if (fs.existsSync(packageJsonFile)) {
          fs.readFile(packageJsonFile, function (err, data) {
            if (err) {

            }

In my case, the above script outputs:

"colors": "0.6.0-1",
"commander": "1.0.5",
"htmlparser": "1.7.6",
"optimist": "0.3.5",
"progress": "0.1.0",
"request": "2.11.4",
"soupselect": "0.2.0",   // Remember: remove the comma character in the last line.

Now, you can copy&paste them. Have fun!

using(StreamWriter writer = new StreamWriter("debug.txt", true))
{
  writer.WriteLine("whatever you text is");
}

The second "true" parameter tells it to append.

As an alternative to installing Visual C++, there is a way by installing an additional package in Conda (this option doesn't require admin rights). This worked for me:

conda install libpython m2w64-toolchain -c msys2

You could sort both lists using Collections.sort() and then use the equals method. A slighly better solution is to first check if they are the same length before ordering, if they are not, then they are not equal, then sort, then use equals. For example if you had two lists of Strings it would be something like:

public  boolean equalLists(List<String> one, List<String> two){     
    if (one == null && two == null){
        return true;
    }

    if((one == null && two != null) 
      || one != null && two == null
      || one.size() != two.size()){
        return false;
    }

    //to avoid messing the order of the lists we will use a copy
    //as noted in comments by A. R. S.
    one = new ArrayList<String>(one); 
    two = new ArrayList<String>(two);   

    Collections.sort(one);
    Collections.sort(two);      
    return one.equals(two);
}

Actually, for the latest JBOSS 7 AS, we need a .dodeploy marker even for archives. So add a marker to trigger the deployment.

In my case, I added a Hello.war.deployed file in the same directory and then everything worked fine.

Hope this helps someone!

1. Open Developer Tools

   • Either F12
   • Or ... -> More Tools -> Developer Tools

2. Click Empty Cache and Hard Reload

   • Either right-click refresh icon (just left to url address bar)
   • Or left-click refresh icon and holding it for 1 second

You're going to have to reformat your releases object to be an array of objects. Then you'll be able to sort them the way you're attempting.

pdf2ps large.pdf small.pdf is enough, instead of two steps

pdf2ps large.pdf very_large.ps 
ps2pdf very_large.ps small.pdf

However, ps2pdf large.pdf small.pdf is a better choice.

• ps2pdf is much faster
• without additional parameters specified, pdf2ps sometimes produces larger file.

Here's a module for calculating SHA1 hashes that is usable for Excel formulas eg. '=SHA1HASH("test")'. To use it, make a new module called 'module_sha1' and copy and paste it all in. This is based on some VBA code from http://vb.wikia.com/wiki/SHA-1.bas, with changes to support passing it a string, and executable from formulas in Excel cells.

None of this solution worked for me since I'm in a cross-domain scenario creating a bookmarklet like Pinterest's Pin It.

I've found a bookmarklet template on GitHub https://gist.github.com/kn0ll/1020251 that solved the problem of closing the Iframe sending the command from within it.

Since I can't access any element from parent window within the IFrame, this communication can only be made posting events between the two windows using window.postMessage

All these steps are on the GitHub link:

1- You have to inject a JS file on the parent page.

2- In this file injected on the parent, add a window event listner

    window.addEventListener('message', function(e) {
       var someIframe = window.parent.document.getElementById('iframeid');
       someIframe.parentNode.removeChild(window.parent.document.getElementById('iframeid'));
    });

This listener will handle the close and any other event you wish

3- Inside the Iframe page you send the close command via postMessage:

   $(this).trigger('post-message', [{
                    event: 'unload-bookmarklet'
                }]);

Follow the template on https://gist.github.com/kn0ll/1020251 and you'll be fine!

Hope it helps,

A very simple/naive approach:

vector<string> words_seperate(string s){
    vector<string> ans;
    string w="";
    for(auto i:s){
        if(i==' '){
           ans.push_back(w);
           w="";
        }
        else{
           w+=i;
        }
    }
    ans.push_back(w);
    return ans;
}

Or you can use boost library split function:

vector<string> result; 
boost::split(result, input, boost::is_any_of("\t"));

Or You can try TOKEN or strtok:

char str[] = "DELIMIT-ME-C++"; 
char *token = strtok(str, "-"); 
while (token) 
{ 
    cout<<token; 
    token = strtok(NULL, "-"); 
} 

Or You can do this:

char split_with=' ';
vector<string> words;
string token; 
stringstream ss(our_string);
while(getline(ss , token , split_with)) words.push_back(token);

CREATE FUNCTION ActionState_Preassigned()
RETURNS tinyint
AS
BEGIN
    RETURN 0
END

GO

CREATE FUNCTION ActionState_Unassigned()
RETURNS tinyint
AS
BEGIN
    RETURN 1
END

-- etc...

Where performance matters, still use the hard values.

Yes, it's possible to To capture div as PDFs in JS. You can can check the solution provided by https://grabz.it. They have nice and clean JavaScript API which will allow you to capture the content of a single HTML element such as a div or a span.

So, yo use it you will need and app+key and the free SDK. The usage of it is as following:

Let's say you have a HTML:

<div id="features">
    <h4>Acme Camera</h4>
    <label>Price</label>$399<br />
    <label>Rating</label>4.5 out of 5
</div>
<p>Cras ut velit sed purus porttitor aliquam. Nulla tristique magna ac libero tempor, ac vestibulum felisvulput ate. Nam ut velit eget
risus porttitor tristique at ac diam. Sed nisi risus, rutrum a metus suscipit, euismod tristique nulla. Etiam venenatis rutrum risus at
blandit. In hac habitasse platea dictumst. Suspendisse potenti. Phasellus eget vehicula felis.</p>

To capture what is under the features id you will need to:

//add the sdk
<script type="text/javascript" src="grabzit.min.js"></script>
<script type="text/javascript">
//login with your key and secret. 
GrabzIt("KEY", "SECRET").ConvertURL("http://www.example.com/my-page.html",
{"target": "#features", "format": "pdf"}).Create();
</script>

You need to replace the http://www.example.com/my-page.html with your target url and #feature per your CSS selector.

That's all. Now, when the page is loaded an image screenshot will now be created in the same location as the script tag, which will contain all of the contents of the features div and nothing else.

The are other configuration and customization you can do to the div-screenshot mechanism, please check them out here

You can do this simply by using pandas drop duplicates function

df.drop_duplicates(['A','B'],keep= 'last')

Just create a file named gradle.properties in the following directory:

/home/<username>/.gradle/ (Linux)
/Users/<username>/.gradle/ (Mac)
C:\Users\<username>\.gradle (Windows)

Add this line to the file:

org.gradle.daemon=true

For me the speed is now equal to Eclipse.

you can use Android Asset in android studio , and android Asset will give you image in this size as a drawable and the application will automatically use the size based on screen of device or emulate

The total of 7 numbers in an array can be created as:

import java.util.*;
class Sum
{
   public static void main(String arg[])
   {
     int a[]=new int[7];
     int total=0;
     Scanner n=new Scanner(System.in);
     System.out.println("Enter the no. for total");

     for(int i=0;i<=6;i++) 
     {
       a[i]=n.nextInt();
       total=total+a[i];
      }
       System.out.println("The total is :"+total);
    }
}

Using in place string concatenation by '+' is THE WORST method of concatenation in terms of stability and cross implementation as it does not support all values. PEP8 standard discourages this and encourages the use of format(), join() and append() for long term use.

As quoted from the linked "Programming Recommendations" section:

For example, do not rely on CPython's efficient implementation of in-place string concatenation for statements in the form a += b or a = a + b. This optimization is fragile even in CPython (it only works for some types) and isn't present at all in implementations that don't use refcounting. In performance sensitive parts of the library, the ''.join() form should be used instead. This will ensure that concatenation occurs in linear time across various implementations.

You are missing the dot on the selector, and you can use toggleClass method on jquery:

$(".result").hover(
  function () {
    $(this).toggleClass("result_hover")      
  }
);

I've literally just arrived at the answer in my case. I'm creating a system that has implemented a create method, so I was getting this actual error because I was accessing the overridden version not the one from Eloquent.

Hope that help?

It's worked for me. Try this:

double od = Double.parseDouble("1.15");
int oi = (int) od;

I found this maven repo where you could download from directly a zip file containing all the jars you need.

• https://maven.springframework.org/release/org/springframework/spring/
• https://repo.spring.io/release/org/springframework/spring/

Alternate solution: Maven

The solution I prefer is using Maven, it is easy and you don't have to download each jar alone. You can do it with the following steps:

1. Create an empty folder anywhere with any name you prefer, for example spring-source

2. Create a new file named pom.xml

3. Copy the xml below into this file

4. Open the spring-source folder in your console

5. Run mvn install

6. After download finished, you'll find spring jars in /spring-source/target/dependencies

   <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

           </executions>
         </plugin>
       </plugins>
     </build>
   </project>
   

Also, if you need to download any other spring project, just copy the dependency configuration from its corresponding web page.

For example, if you want to download Spring Web Flow jars, go to its web page, and add its dependency configuration to the pom.xml dependencies, then run mvn install again.

<dependency>
  <groupId>org.springframework.webflow</groupId>
  <artifactId>spring-webflow</artifactId>
  <version>2.3.2.RELEASE</version>
</dependency>

Your build script should match with application build.gradle dependencies.

ext {
        buildToolsVersion = "27.0.3"
        minSdkVersion = 16
        compileSdkVersion = 27
        targetSdkVersion = 26
        supportLibVersion = "27.1.1"
    }


dependencies {
    .................
    ...................

    implementation 'com.android.support:support-v4:27.1.0'
    implementation 'com.android.support:design:27.1.0'
    ................
    ...........
}

if you want to downgrade dependencies then also downgrade supportLibVersion and buildToolsVersion .

I found one way to supply credentials for a https connection on the command line. You just need to specify the complete URL to git pull and include the credentials there:

git pull https://username:[email protected]/my/repository

You do not need to have the repository cloned with the credentials before, this means your credentials don't end up in .git/config. (But make sure your shell doesn't betray you and stores the command line in a history file.)

You can connect two iPhones and transfer data via Bluetooth using either the high-level GameKit framework or the lower-level (but still easy to work with) Bonjour discovery mechanisms. Bonjour also works transparently between Bluetooth and WiFi on the iPhone under 3.0, so it's a good choice if you would like to support iPhone-to-iPhone data transfers on those two types of networks.

For more information, you can also look at the responses to these questions:

• "where can I find iphone sdk 3.0 GameKit tutorials for developing P2P applications?"
• "iPhone to iPhone networking"
• "GameKit in iPhone SDK 3.0"
• "Is iPhone bluetooth function limited in OS 3.0?"

In my case,

    word-break: break-all;

worked perfecly, hope it helps any other newcomer like me.

        $result = curl_exec($ch);                   

        if(false === $result ) {
            echo curl_error($ch);
        }
        curl_close($ch);

        return $result; 
    }
}

I have created some simple function you can use to convert time to any timezone :

function convertTimeToLocal($datetime,$timezone='Europe/Dublin') {
        $given = new DateTime($datetime, new DateTimeZone("UTC"));
        $given->setTimezone(new DateTimeZone($timezone));
        $output = $given->format("Y-m-d"); //can change as per your requirement
        return $output;
}

One of the most classic ones is the comment made by Pierre de Fermat about his well-known "Last theorem": "The margin of this page is a bit too small to write down the proof".

It took more than 350 years before the proof was found...

(According to wikipedia this is the original text:)

Cubum autem in duos cubos, aut quadratoquadratum in duos quadratoquadratos, et generaliter nullam in infinitum ultra quadratum potestatem in duos eiusdem nominis fas est dividere cuius rei demonstrationem mirabilem sane detexi. Hanc marginis exiguitas non caperet.

...and translated into English:

(It is impossible to separate a cube into two cubes, or a fourth power into two fourth powers, or in general, any power higher than the second into two like powers. I have discovered a truly marvellous proof of this, which this margin is too narrow to contain.)

my friend by this u are not getting height of image stored in db.but you are getting view height.for getting height of image u have to create bitmap from db,s image.and than u can fetch height and width of imageview

This is work for me !

<script type="text/javascript">
$(document).ready(function(){

You can use exceptional handling as str.digit will only work for integers and can fail for something like this too:

>>> str.isdigit(' 1')
False

Using a generator function:

def solve(lis):                                        
    for x in lis:
        try:
            yield float(x)
        except ValueError:    
            pass

>>> mylist = ['1','orange','2','3','4','apple', '1.5', '2.6']
>>> list(solve(mylist))                                    
[1.0, 2.0, 3.0, 4.0, 1.5, 2.6]   #returns converted values

or may be you wanted this:

def solve(lis):
    for x in lis:
        try:
            float(x)
            return True
        except:
            return False
...         
>>> mylist = ['1','orange','2','3','4','apple', '1.5', '2.6']
>>> [x for x in mylist if solve(x)]
['1', '2', '3', '4', '1.5', '2.6']

or using ast.literal_eval, this will work for all types of numbers:

>>> from ast import literal_eval
>>> def solve(lis):
    for x in lis:
        try:
            literal_eval(x)
            return True
        except ValueError:   
             return False
...         
>>> mylist=['1','orange','2','3','4','apple', '1.5', '2.6', '1+0j']
>>> [x for x in mylist if solve(x)]                               
['1', '2', '3', '4', '1.5', '2.6', '1+0j']

Well, I got it. One way is to override the QWidget::closeEvent(QCloseEvent *event) method in your class definition and add your code into that function. Example:

class foo : public QMainWindow
{
    Q_OBJECT
private:
    void closeEvent(QCloseEvent *bar);
    // ...
};


void foo::closeEvent(QCloseEvent *bar)
{
    // Do something
    bar->accept();
}

For any users having the same issue in 2017, I solved it the following way:

NavBar.contextTypes = {
    router: React.PropTypes.object,
    location: React.PropTypes.object
}

and use it like this:

componentDidMount () {
    console.log(this.context.location.pathname);
}

It is a little difficult to answer your specific question without a full, reproducible example. However something like this should work:

#Turn your 'treatment' column into a character vector
data$Treatment <- as.character(data$Treatment)
#Then turn it back into a factor with the levels in the correct order
data$Treatment <- factor(data$Treatment, levels=unique(data$Treatment))

In this example, the order of the factor will be the same as in the data.csv file.

If you prefer a different order, you can order them by hand:

data$Treatment <- factor(data$Treatment, levels=c("Y", "X", "Z"))

However this is dangerous if you have a lot of levels: if you get any of them wrong, that will cause problems.

vector<pair<int,int> >a;

for (i = 0 ;i < n ; i++) {
    // filling the original array
    cin >> k;
    a.push_back (make_pair (k,i)); // k = value, i = original index
}

sort (a.begin(),a.end());

for (i = 0 ; i < n ; i++){
    cout << a[i].first << " " << a[i].second << "\n";
}

Now a contains both both our values and their respective indices in the sorted.

a[i].first = value at i'th.

a[i].second = idx in initial array.

It failed because you used ajax="false". This fires a full synchronous request which in turn causes a full page reload, causing the oncomplete to be never fired (note that all other ajax-related attributes like process, onstart, onsuccess, onerror and update are also never fired).

That it worked when you removed actionListener is also impossible. It should have failed the same way. Perhaps you also removed ajax="false" along it without actually understanding what you were doing. Removing ajax="false" should indeed achieve the desired requirement.

Also is it possible to execute actionlistener and oncomplete simultaneously?

No. The script can only be fired before or after the action listener. You can use onclick to fire the script at the moment of the click. You can use onstart to fire the script at the moment the ajax request is about to be sent. But they will never exactly simultaneously be fired. The sequence is as follows:

• User clicks button in client
• onclick JavaScript code is executed
• JavaScript prepares ajax request based on process and current HTML DOM tree
• onstart JavaScript code is executed
• JavaScript sends ajax request from client to server
• JSF retrieves ajax request
• JSF processes the request lifecycle on JSF component tree based on process
• actionListener JSF backing bean method is executed
• action JSF backing bean method is executed
• JSF prepares ajax response based on update and current JSF component tree
• JSF sends ajax response from server to client
• JavaScript retrieves ajax response
  • if HTTP response status is 200, onsuccess JavaScript code is executed
  • else if HTTP response status is 500, onerror JavaScript code is executed
• JavaScript performs update based on ajax response and current HTML DOM tree
• oncomplete JavaScript code is executed

Note that the update is performed after actionListener, so if you were using onclick or onstart to show the dialog, then it may still show old content instead of updated content, which is poor for user experience. You'd then better use oncomplete instead to show the dialog. Also note that you'd better use action instead of actionListener when you intend to execute a business action.

In case anyone finds it useful, www.querymongo.com does translation between SQL and MongoDB, including OR clauses. It can be really helpful for figuring out syntax when you know the SQL equivalent.

In the case of OR statements, it looks like this

SQL:

SELECT * FROM collection WHERE columnA = 3 OR columnB = 'string';

MongoDB:

db.collection.find({
    "$or": [{
        "columnA": 3
    }, {
        "columnB": "string"
    }]
});

If you don't want to jQuery, here's the vanilla JavaScript:

///Mute
var video = document.getElementById("your-video-id");
video.muted= true;

//Unmute
var video = document.getElementById("your-video-id");
video.muted= false;

It will work for audio too, just put the element's id and it will work (and change the var name if you want, to 'media' or something suited for both audio/video as you like).

Decode it.

>>> b'a string'.decode('ascii')
'a string'

To get bytes from string, encode it.

>>> 'a string'.encode('ascii')
b'a string'

Try to look for an updated method, since Boto3 might change from time to time. I used my_bucket.delete_objects():

import boto3
from boto3.session import Session

session = Session(aws_access_key_id='your_key_id',
                  aws_secret_access_key='your_secret_key')

# s3_client = session.client('s3')
s3_resource = session.resource('s3')
my_bucket = s3_resource.Bucket("your_bucket_name")

response = my_bucket.delete_objects(
    Delete={
        'Objects': [
            {
                'Key': "your_file_name_key"   # the_name of_your_file
            }
        ]
    }
)

You can use something like:

<beans>
    <bean id="myBean" class="..." init-method="init"/>
</beans>

This will call the "init" method when the bean is instantiated.

Though the first approach is advocated as 'the angular like' approach, I feel this adds overheads.

Consider if I want to use this myservice.foo function in 10 different controllers. I will have to specify this 'myService' dependency and then $scope.callFoo scope property in all ten of them. This is simply a repetition and somehow violates the DRY principle.

Whereas, if I use the $rootScope approach, I specify this global function gobalFoo only once and it will be available in all my future controllers, no matter how many.

None of these responses really seem to answer the question. Here's something similar to what I'm utilizing on a site of mine by targeting a menu item by its title/name:

function add_class_to_menu_item($sorted_menu_objects, $args) {
    $theme_location = 'primary_menu';  // Name, ID, or Slug of the target menu location
    $target_menu_title = 'Link';  // Name/Title of the menu item you want to target
    $class_to_add = 'my_own_class';  // Class you want to add

    if ($args->theme_location == $theme_location) {
        foreach ($sorted_menu_objects as $key => $menu_object) {
            if ($menu_object->title == $target_menu_title) {
                $menu_object->classes[] = $class_to_add;
                break; // Optional.  Leave if you're only targeting one specific menu item
            }
        }
    }

    return $sorted_menu_objects;
}
add_filter('wp_nav_menu_objects', 'add_class_to_menu_item', 10, 2);

I'm not sure if this is 100% portable but the way the OS SHOULD parse the args is to scan through the console command string and insert a nil-term char at the end of each token, and int main(int,char**) doesn't use const char** so we can just iterate through the args starting from the third argument (@note the first arg is the working directory) and scan backward to the nil-term char and turn it into a space rather than start from beginning of the second argument and scanning forward to the nil-term char. Here is the function with test script, and if you do need to un-nil-ify more than one nil-term char then please comment so I can fix it; thanks.

#include <cstdio>
#include <iostream>

using namespace std;

namespace _ {
/* Converts int main(int,char**) arguments back into a string.
@return false if there are no args to convert.
@param arg_count The number of arguments.
@param args      The arguments. */
bool ArgsToString(int args_count, char** args) {
  if (args_count <= 1) return false;
  if (args_count == 2) return true;
  for (int i = 2; i < args_count; ++i) {
    char* cursor = args[i];
    while (*cursor) --cursor;
    *cursor = ' ';
  }
  return true;
}
}  // namespace _

int main(int args_count, char** args) {
  cout << "\n\nTesting ArgsToString...\n";

  if (args_count <= 1) return 1;
  cout << "\nArguments:\n";
  for (int i = 0; i < args_count; ++i) {
    char* arg = args[i];
    printf("\ni:%i\"%s\" 0x%p", i, arg, arg);
  }
  cout << "\n\nContiguous Args:\n";
  char* end = args[args_count - 1];
  while (*end) ++end;
  cout << "\n\nContiguous Args:\n";
  char* cursor = args[0];
  while (cursor != end) {
    char c = *cursor++;
    if (c == 0)
      cout << '`';
    else if (c < ' ')
      cout << '~';
    else
      cout << c;
  }
  cout << "\n\nPrinting argument string...\n";
  _::ArgsToString(args_count, args);
  cout << "\n" << args[1];
  return 0;
}

Here's the real solution (with other cool CSS3 stuff):

#fixed-square {
position: fixed;
top: 0;
right: 0;
z-index: 9500;
cursor: pointer;
width: 24px;
padding: 18px 18px 14px;
opacity: 0.618;
-webkit-transform: rotate(-90deg);
-moz-transform: rotate(-90deg);
-ms-transform: rotate(-90deg);
transform: rotate(-90deg);
-webkit-transition: all 0.145s ease-out;
-moz-transition: all 0.145s ease-out;
-ms-transition: all 0.145s ease-out;
transition: all 0.145s ease-out;
}

Note the top:0 and right:0. That's what did it for me.

To make it clear, in addition to @SLaks' answer, that meant you need to change this line :

List<RootObject> datalist = JsonConvert.DeserializeObject<List<RootObject>>(jsonstring);

to something like this :

RootObject datalist = JsonConvert.DeserializeObject<RootObject>(jsonstring);

In my case, I was getting this problem because of getting data updates from server (I am using Firebase Firestore) and while the first set of data is being processed by DiffUtil in the background, another set of data update comes and causes a concurrency issue by starting another DiffUtil.

In short, if you are using DiffUtil on a Background thread which then comes back to the Main Thread to dispatch the results to the RecylerView, then you run the chance of getting this error when multiple data updates come in short time.

I solved this by following the advice in this wonderful explanation: https://medium.com/@jonfhancock/get-threading-right-with-diffutil-423378e126d2

Just to explain the solution is to push the updates while the current one is running to a Deque. The deque can then run the pending updates once the current one finishes, hence handling all subsequent updates but avoiding inconsistency errors as well!

Hope this helps because this one made me scratch my head!

Try something like this:

#include <signal.h>

pid_t child_pid = -1 ; //Global

void kill_child(int sig)
{
    kill(child_pid,SIGKILL);
}

int main(int argc, char *argv[])
{
    signal(SIGALRM,(void (*)(int))kill_child);
    child_pid = fork();
    if (child_pid > 0) {
     /*PARENT*/
        alarm(30);
        /*
         * Do parent's tasks here.
         */
        wait(NULL);
    }
    else if (child_pid == 0){
     /*CHILD*/
        /*
         * Do child's tasks here.
         */
    }
}

I used this tutorial to create my maven web project http://crunchify.com/how-to-create-dynamic-web-project-using-maven-in-eclipse/ and eclipse did not create src/main/java folder for me. When i tired to create the source folder src/main/java eclipse did not let me. So i created the folder outside eclipse in the project directly and then src/main/java appeared in eclipse.

On Windows 8.1 I had to run cmd.exe as administrator (even though I was logged in as admin). Otherwise I got an error when trying to execute: httpd.exe -k uninstall

Error: C:\Program Files\Apache\bin>(OS 5)Access is denied. : AH00373: Apache2.4: OpenS ervice failed

Play 2.2.0 on Windows

Using a zip distribution (produced using the "dist" command), the only way I was able to change the startup port was by first setting JAVA_OPTS and then launching the application.

E.g., from the command line

set JAVA_OPTS=-Dhttp.port=9002
bin\myapp.bat

where myapp.bat is the batch file created by the "dist" command.

The following would always ignore my http.port parameter and attempt to start on the default port, 9000

bin\myapp.bat -Dhttp.port=9002

However, I've noticed that this works fine on Linux/OSX, starting up on the requested port:

./bin/myapp -Dhttp.port=9002

html code in my case

<ul class="navs">
   <li  id="tab1"><a href="index-2.html">home</a></li>
   <li id="tab2"><a href="about.html">about</a></li>

   <li id="tab3"><a href="project-02.html">Products</a></li>

   <li id="tab4"><a href="contact.html">contact</a></li>
 </ul>

and js code is

  $('.navs li a').click(function (e) {
        var $parent = $(this).parent();
        document.cookie = eraseCookie("tab");
        document.cookie = createCookie("tab", $parent.attr('id'),0);
 });

    $().ready(function () {
        var $activeTab = readCookie("tab");
        if (!$activeTab =="") {
        $('#tab1').removeClass('ActiveTab');
          }
       // alert($activeTab.toString());

        $('#'+$activeTab).addClass('active');
    });

function createCookie(name, value, days) {
    if (days) {
        var date = new Date();
        date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
        var expires = "; expires=" + date.toGMTString();
    }
    else var expires = "";

    document.cookie = name + "=" + value + expires + "; path=/";
}

function readCookie(name) {
    var nameEQ = name + "=";
    var ca = document.cookie.split(';');
    for (var i = 0; i < ca.length; i++) {
        var c = ca[i];
        while (c.charAt(0) == ' ') c = c.substring(1, c.length);
        if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length, c.length);
    }
    return null;

Take a look at http://www.csharp-examples.net/download-files/ and msdn docs on webclient http://msdn.microsoft.com/en-us/library/system.net.webclient.aspx

My suggestion is try the synchronous download as its more straightforward. you might get ideas on whether webclient parameters are wrong or the file is in incorrect format while trying this.

Here is a code sample..

private void btnDownload_Click(object sender, EventArgs e)
{
  string filepath = textBox1.Text;
  WebClient webClient = new WebClient();
  webClient.DownloadFileCompleted += new AsyncCompletedEventHandler(Completed);
  webClient.DownloadProgressChanged += new DownloadProgressChangedEventHandler(ProgressChanged);
  webClient.DownloadFileAsync(new Uri("http://mysite.com/myfile.txt"), filepath);
}

private void ProgressChanged(object sender, DownloadProgressChangedEventArgs e)
{
  progressBar.Value = e.ProgressPercentage;
}

private void Completed(object sender, AsyncCompletedEventArgs e)
{
  MessageBox.Show("Download completed!");
}

We can read properties file in spring boot using 3 way

1. Read value from application.properties Using @Value

map key as

public class EmailService {

 @Value("${email.username}")
 private String username;

}

2. Read value from application.properties Using @ConfigurationProperties

In this we will map prefix of key using ConfigurationProperties and key name is same as field of class

  @Component
   @ConfigurationProperties("email")
    public class EmailConfig {

        private String   username;
    }

3. Read application.properties Using using Environment object

public class EmailController {

@Autowired
private Environment env;

@GetMapping("/sendmail")
public void sendMail(){     
    System.out.println("reading value from application properties file  using Environment ");
    System.out.println("username ="+ env.getProperty("email.username"));
    System.out.println("pwd ="+ env.getProperty("email.pwd"));
}

What is a patch?

A patch is little more (see below) than a series of instructions: "add this here", "remove that there", "change this third thing to a fourth". That's why git tells you:

The copy of the patch that failed is found in:
c:/.../project2/.git/rebase-apply/patch

You can open that patch in your favorite viewer or editor, open the files-to-be-changed in your favorite editor, and "hand apply" the patch, using what you know (and git does not) to figure out how "add this here" is to be done when the files-to-be-changed now look little or nothing like what they did when they were changed earlier, with those changes delivered to you as a patch.

A little more

A three-way merge introduces that "little more" information than the plain "series of instructions": it tells you what the original version of the file was as well. If your repository has the original version, your git can compare what you did to a file, to what the patch says to do to the file.

As you saw above, if you request the three-way merge, git can't find the "original version" in the other repository, so it can't even attempt the three-way merge. As a result you get no conflict markers, and you must do the patch-application by hand.

Using --reject

When you have to apply the patch by hand, it's still possible that git can apply most of the patch for you automatically and leave only a few pieces to the entity with the ability to reason about the code (or whatever it is that needs patching). Adding --reject tells git to do that, and leave the "inapplicable" parts of the patch in rejection files. If you use this option, you must still hand-apply each failing patch, and figure out what to do with the rejected portions.

Once you have made the required changes, you can git add the modified files and use git am --continue to tell git to commit the changes and move on to the next patch.

What if there's nothing to do?

Since we don't have your code, I can't tell if this is the case, but sometimes, you wind up with one of the patches saying things that amount to, e.g., "fix the spelling of a word on line 42" when the spelling there was already fixed.

In this particular case, you, having looked at the patch and the current code, should say to yourself: "aha, this patch should just be skipped entirely!" That's when you use the other advice git already printed:

If you prefer to skip this patch, run "git am --skip" instead.

If you run git am --skip, git will skip over that patch, so that if there were five patches in the mailbox, it will end up adding just four commits, instead of five (or three instead of five if you skip twice, and so on).

I solved it by putting this:

@Override
protected void onDestroy() {
    accessTokenTracker.stopTracking();
    super.onDestroy();
}

This should give you the required layout:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <ImageView
        android:id="@+id/flag"
        android:layout_width="fill_parent"
        android:layout_height="250dp"
        android:layout_alignParentLeft="true"
        android:layout_alignParentRight="true"
        android:scaleType="fitXY"
        android:src="@drawable/ic_launcher" />

    <TextView
        android:id="@+id/textview"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_marginTop="20dp"
        android:layout_centerHorizontal="true" />

</RelativeLayout>

Play with the android:layout_marginTop="20dp" to see which one suits you better. Use the id textview to dynamically set the android:text value.

Since a RelativeLayout stacks its children, defining the TextView after ImageView puts it 'over' the ImageView.

NOTE: Similar results can be obtained using a FrameLayout as the parent, along with the efficiency gain over using any other android container. Thanks to Igor Ganapolsky(see comment below) for pointing out that this answer needs an update.

I came up with the following extension that takes care of removing elements from an Array, assuming the elements in the Array implement Equatable:

extension Array where Element: Equatable {
  
  mutating func removeEqualItems(_ item: Element) {
    self = self.filter { (currentItem: Element) -> Bool in
      return currentItem != item
    }
  }

  mutating func removeFirstEqualItem(_ item: Element) {
    guard var currentItem = self.first else { return }
    var index = 0
    while currentItem != item {
      index += 1
      currentItem = self[index]
    }
    self.remove(at: index)
  }
  
}
  

Usage:

var test1 = [1, 2, 1, 2]
test1.removeEqualItems(2) // [1, 1]

var test2 = [1, 2, 1, 2]
test2.removeFirstEqualItem(2) // [1, 1, 2]

All the selector crap api doesn't work as expected. After trying all the solutions presented in this thread to no good, we just solved the problem at the moment of inflating the ListView Item.

1. Make sure your item keeps it's state, we did it as a member variable of the MenuItem (boolean selected)

2. When you inflate, ask if the underlying item is selected, if so, just set the drawable resource that you want as the background (be it a 9patch or whatever). Make sure your adapter is aware of this and that it calls notifyDataChanged() when something has been selected.

       @Override
   public View getView(int position, View convertView, ViewGroup parent) {
       View rowView = convertView;
       if (rowView == null) {
           LayoutInflater inflater = act.getLayoutInflater();
           rowView = inflater.inflate(R.layout.slidemenu_listitem, null);
           MenuItemHolder viewHolder = new MenuItemHolder();
           viewHolder.label = (TextView) rowView.findViewById(R.id.slidemenu_item_label);
           viewHolder.icon = (ImageView) rowView.findViewById(R.id.slidemenu_item_icon);
           rowView.setTag(viewHolder);
       }
   
       MenuItemHolder holder = (MenuItemHolder) rowView.getTag();
       String s = items[position].label;
       holder.label.setText(s);
       holder.icon.setImageDrawable(items[position].icon);
   
       //Here comes the magic
       rowView.setSelected(items[position].selected);
   
       rowView.setBackgroundResource((rowView.isSelected()) ? R.drawable.slidemenu_item_background_selected : R.drawable.slidemenu_item_background);
   
       return rowView;
   }
   

It'd be really nice if the selectors would actually work, in theory it's a nice and elegant solution, but it seems like it's broken. KISS.

I was able to successfully pass through the data attribute in the ajax method. Here is my code

$.ajax({
     url: "/api/Gigs/Cancel",
     type: "DELETE",
     data: {
             "GigId": link.attr('data-gig-id')
           }

  })

The link.attr method simply returned the value of 'data-gig-id' .

Simply follow the instructions given here:

Example install:

sudo apt-get install python-software-properties python g++ make
sudo add-apt-repository ppa:chris-lea/node.js
sudo apt-get update
sudo apt-get install nodejs

It installs current stable Node on the current stable Ubuntu. Quantal (12.10) users may need to install the software-properties-common package for the add-apt-repository command to work: sudo apt-get install software-properties-common

As of Node.js v0.10.0, the nodejs package from Chris Lea's repo includes both npm and nodejs-dev.

Don't give sudo apt-get install nodejs npm. Just sudo apt-get install nodejs.

Full recursive routing of all .js files inside /routes folder, put this in app.js.

// Initialize ALL routes including subfolders
var fs = require('fs');
var path = require('path');

function recursiveRoutes(folderName) {
    fs.readdirSync(folderName).forEach(function(file) {

        var fullName = path.join(folderName, file);
        var stat = fs.lstatSync(fullName);

        if (stat.isDirectory()) {
            recursiveRoutes(fullName);
        } else if (file.toLowerCase().indexOf('.js')) {
            require('./' + fullName)(app);
            console.log("require('" + fullName + "')");
        }
    });
}
recursiveRoutes('routes'); // Initialize it

in /routes you put whatevername.js and initialize your routes like this:

module.exports = function(app) {
    app.get('/', function(req, res) {
        res.render('index', { title: 'index' });
    });

    app.get('/contactus', function(req, res) {
        res.render('contactus', { title: 'contactus' });
    });
}

you can use this to get the data of the last 30 days based on a column.

WHERE DATEDIFF(dateColumn,CURRENT_TIMESTAMP) BETWEEN 0 AND 30

Write the following code inside AppDelegate.m in didFinishLaunchingWithOptions event (exactly before its last line of code "return YES;" ) :

if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7) 
{
    [application setStatusBarHidden:YES withAnimation:UIStatusBarAnimationNone];
}

I'll wait for your feedback! :)

You need to link with the math library:

gcc -o sphere sphere.c -lm

The error you are seeing: error: ld returned 1 exit status is from the linker ld (part of gcc that combines the object files) because it is unable to find where the function pow is defined.

Including math.h brings in the declaration of the various functions and not their definition. The def is present in the math library libm.a. You need to link your program with this library so that the calls to functions like pow() are resolved.

Here a solution that:

1. uses URLSearchParams (no difficult to understand regex)
2. updates the URL in the search bar without reload
3. maintains all other parts of the URL (e.g. hash)
4. removes superflous ? in query string if the last parameter was removed

function removeParam(paramName) {
    let searchParams = new URLSearchParams(window.location.search);
    searchParams.delete(paramName);
    if (history.replaceState) {
        let searchString = searchParams.toString().length > 0 ? '?' + searchParams.toString() : '';
        let newUrl = window.location.protocol + "//" + window.location.host + window.location.pathname +  searchString + window.location.hash;
        history.replaceState(null, '', newUrl);
    }
}

Note: as pointed out in other answers URLSearchParams is not supported in IE, so use a polyfill.

You need to use cat to get the contents of the file named 'DSC_0251.JPG', rather than the filename itself.

test="$(cat DSC_0251.JPG | base64)"

However, base64 can read from the file itself:

test=$( base64 DSC_0251.JPG )

If you're ok with using a third party library, check out traex/RippleEffect. It allows you to add a Ripple effect to ANY view with just a few lines of code. You just need to wrap, in your xml layout file, the element you want to have a ripple effect with a com.andexert.library.RippleView container.

As an added bonus it requires Min SDK 9 so you can have design consistency across OS versions.

Here's an example taken from the libraries' GitHub repo:

<com.andexert.library.RippleView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:rv_centered="true">

    <ImageView
        android:layout_width="100dp"
        android:layout_height="100dp"
        android:src="@android:drawable/ic_menu_edit"
        android:background="@android:color/holo_blue_dark"/> 

</com.andexert.library.RippleView>

You can change the ripple colour by adding this attribute the the RippleView element: app:rv_color="@color/my_fancy_ripple_color

Another way is to use the DateTime class, this way you can also specify the timezone. Note: PHP 5.3 or higher.

// For the current date
function isTodayWeekend() {
    $currentDate = new DateTime("now", new DateTimeZone("Europe/Amsterdam"));
    return $currentDate->format('N') >= 6;
}

If you need to be able to check a certain date string, you can use DateTime::createFromFormat

function isWeekend($date) {
    $inputDate = DateTime::createFromFormat("d-m-Y", $date, new DateTimeZone("Europe/Amsterdam"));
    return $inputDate->format('N') >= 6;
}

The beauty of this way is that you can specify the timezone without changing the timezone globally in PHP, which might cause side-effects in other scripts (for ex. Wordpress).

Let's consider that the environment that one wants to update has the name venv.

1. Backup venv requirementes (optional)

First of all, backup the requirements of the virtual environment:

pip freeze > requirements.txt
deactivate
#Move the folder to a new one
mv venv venv_old

2. Install Python

Assuming that one doesn't have sudo access, pyenv is a reliable and fast way to install Python. For that, one should run

$ curl https://pyenv.run | bash

and then

$ exec $SHELL

As it is suggested here.

If, when one tries to update pyenv

pyenv update

And one gets the error

bash: pyenv: command not found

It is because pyenv path wasn't exported to .bashrc. It can be solved by executing the following commands:

echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.bashrc
echo 'export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.bashrc
echo -e 'if command -v pyenv 1>/dev/null 2>&1; then\n eval "$(pyenv init -)"\nfi' >> ~/.bashrc

Then restart the shell

exec "$SHELL"

Now one should install the Python version that one wants. Let's say version 3.8.3

pyenv install 3.8.3

One can confirm if it was properly installed by running

pyenv versions

The output should be the location and the versions (in this case 3.8.3)

3. Create the new virtual environment

Finally, with the new Python version installed, create a new virtual environment (let's call it venv)

python3.8 -m venv venv

Activate it

source venv/bin/activate

and install the requirements

pip install -r requirements.txt

Now one should be up and running with a new environment.

Readers should notice that the key= method:

ut.sort(key=lambda x: x.count, reverse=True)

is many times faster than adding rich comparison operators to the objects. I was surprised to read this (page 485 of "Python in a Nutshell"). You can confirm this by running tests on this little program:

#!/usr/bin/env python
import random

class C:
    def __init__(self,count):
        self.count = count

    def __cmp__(self,other):
        return cmp(self.count,other.count)

longList = [C(random.random()) for i in xrange(1000000)] #about 6.1 secs
longList2 = longList[:]

longList.sort() #about 52 - 6.1 = 46 secs
longList2.sort(key = lambda c: c.count) #about 9 - 6.1 = 3 secs

My, very minimal, tests show the first sort is more than 10 times slower, but the book says it is only about 5 times slower in general. The reason they say is due to the highly optimizes sort algorithm used in python (timsort).

Still, its very odd that .sort(lambda) is faster than plain old .sort(). I hope they fix that.

Alternatively, try removing "data" and making the URL "logtime.php?userID="+userId

I like Brian's answer better, this answer is just because you're trying to use URL parameter syntax in "data" and I wanted to demonstrate where you can use that syntax correctly.

Another way is to reverse before and after cut:

$ echo ab:cd:ef | rev | cut -d: -f1 | rev
ef

This makes it very easy to get the last but one field, or any range of fields numbered from the end.

In my case I needed to substract 1 month to current date. The important part was the month number, so it doesn't care in which day of the current month you are at, I needed last month. This is my code:

var dateObj = new Date('2017-03-30 00:00:00'); //Create new date object
console.log(dateObj); // Thu Mar 30 2017 00:00:00 GMT-0300 (ART)

dateObj.setDate(1); //Set first day of the month from current date
dateObj.setDate(-1); // Substract 1 day to the first day of the month

//Now, you are in the last month
console.log(dateObj); // Mon Feb 27 2017 00:00:00 GMT-0300 (ART)

Substract 1 month to actual date it's not accurate, that's why in first place I set first day of the month (first day of any month always is first day) and in second place I substract 1 day, which always send you to last month. Hope to help you dude.

var dateObj = new Date('2017-03-30 00:00:00'); //Create new date object_x000D_
console.log(dateObj); // Thu Mar 30 2017 00:00:00 GMT-0300 (ART)_x000D_
_x000D_
dateObj.setDate(1); //Set first day of the month from current date_x000D_
dateObj.setDate(-1); // Substract 1 day to the first day of the month_x000D_
_x000D_
//Now, you are in the last month_x000D_
console.log(dateObj); // Mon Feb 27 2017 00:00:00 GMT-0300 (ART)

I have a Class (Hash) to convert plain text in hash in formats: md5 or sha1, simillar that php functions (md5, sha1):

public class Hash {
    /**
     * 
     * @param txt, text in plain format
     * @param hashType MD5 OR SHA1
     * @return hash in hashType 
     */
    public static String getHash(String txt, String hashType) {
        try {
                    java.security.MessageDigest md = java.security.MessageDigest.getInstance(hashType);
                    byte[] array = md.digest(txt.getBytes());
                    StringBuffer sb = new StringBuffer();
                    for (int i = 0; i < array.length; ++i) {
                        sb.append(Integer.toHexString((array[i] & 0xFF) | 0x100).substring(1,3));
                 }
                    return sb.toString();
            } catch (java.security.NoSuchAlgorithmException e) {
                //error action
            }
            return null;
    }

    public static String md5(String txt) {
        return Hash.getHash(txt, "MD5");
    }

    public static String sha1(String txt) {
        return Hash.getHash(txt, "SHA1");
    }
}

Testing with JUnit and PHP

PHP Script:

<?php

echo 'MD5 :' . md5('Hello World') . "\n";
echo 'SHA1:' . sha1('Hello World') . "\n";

Output PHP script:

MD5 :b10a8db164e0754105b7a99be72e3fe5
SHA1:0a4d55a8d778e5022fab701977c5d840bbc486d0

Using example and Testing with JUnit:

    public class HashTest {

    @Test
    public void test() {
        String txt = "Hello World";
        assertEquals("b10a8db164e0754105b7a99be72e3fe5", Hash.md5(txt));
        assertEquals("0a4d55a8d778e5022fab701977c5d840bbc486d0", Hash.sha1(txt));
    }

}

Code in GitHub

https://github.com/fitorec/java-hashes

When I've stumbled upon this problem I usually start looking at the places where I FreeAndNil() or just xxx := NIL; variables and the code after that.

When nothing else has helped I've added a Log() function to output messages from various suspect places during execution, and then later looked at that log to trace where in the code the access violation comes.

There are ofcourse many more elegant solutions available for tracing these violations, but if you do not have them at your disposal the old-fashioned trial & error method works fine.

This specifies the default collation for the database. Every text field that you create in tables in the database will use that collation, unless you specify a different one.

A database always has a default collation. If you don't specify any, the default collation of the SQL Server instance is used.

The name of the collation that you use shows that it uses the Latin1 code page 1, is case insensitive (CI) and accent sensitive (AS). This collation is used in the USA, so it will contain sorting rules that are used in the USA.

The collation decides how text values are compared for equality and likeness, and how they are compared when sorting. The code page is used when storing non-unicode data, e.g. varchar fields.

You can access capturing groups like this:

var myString = "something format_abc";_x000D_
var myRegexp = /(?:^|\s)format_(.*?)(?:\s|$)/g;_x000D_
var match = myRegexp.exec(myString);_x000D_
console.log(match[1]); // abc

And if there are multiple matches you can iterate over them:

var myString = "something format_abc";_x000D_
var myRegexp = /(?:^|\s)format_(.*?)(?:\s|$)/g;_x000D_
match = myRegexp.exec(myString);_x000D_
while (match != null) {_x000D_
  // matched text: match[0]_x000D_
  // match start: match.index_x000D_
  // capturing group n: match[n]_x000D_
  console.log(match[0])_x000D_
  match = myRegexp.exec(myString);_x000D_
}

Edit: 2019-09-10

As you can see the way to iterate over multiple matches was not very intuitive. This lead to the proposal of the String.prototype.matchAll method. This new method is expected to ship in the ECMAScript 2020 specification. It gives us a clean API and solves multiple problems. It has been started to land on major browsers and JS engines as Chrome 73+ / Node 12+ and Firefox 67+.

The method returns an iterator and is used as follows:

const string = "something format_abc";_x000D_
const regexp = /(?:^|\s)format_(.*?)(?:\s|$)/g;_x000D_
const matches = string.matchAll(regexp);_x000D_
    _x000D_
for (const match of matches) {_x000D_
  console.log(match);_x000D_
  console.log(match.index)_x000D_
}

As it returns an iterator, we can say it's lazy, this is useful when handling particularly large numbers of capturing groups, or very large strings. But if you need, the result can be easily transformed into an Array by using the spread syntax or the Array.from method:

function getFirstGroup(regexp, str) {
  const array = [...str.matchAll(regexp)];
  return array.map(m => m[1]);
}

// or:
function getFirstGroup(regexp, str) {
  return Array.from(str.matchAll(regexp), m => m[1]);
}

In the meantime, while this proposal gets more wide support, you can use the official shim package.

Also, the internal workings of the method are simple. An equivalent implementation using a generator function would be as follows:

function* matchAll(str, regexp) {
  const flags = regexp.global ? regexp.flags : regexp.flags + "g";
  const re = new RegExp(regexp, flags);
  let match;
  while (match = re.exec(str)) {
    yield match;
  }
}

A copy of the original regexp is created; this is to avoid side-effects due to the mutation of the lastIndex property when going through the multple matches.

Also, we need to ensure the regexp has the global flag to avoid an infinite loop.

I'm also happy to see that even this StackOverflow question was referenced in the discussions of the proposal.

The Ruby-way (TM) since Ruby 2.3: Use the squiggly HEREDOC <<~ to define a multi-line string with newlines and proper indentation:

conn.exec <<~EOS
            select attr1, attr2, attr3, attr4, attr5, attr6, attr7
            from table1, table2, table3, etc, etc, etc, etc, etc
            where etc etc etc etc etc etc etc etc etc etc etc etc etc
          EOS

# -> "select...\nfrom...\nwhere..."

If proper indentation is not a concern, then single and double quotes can span multiple lines in Ruby:

conn.exec "select attr1, attr2, attr3, attr4, attr5, attr6, attr7 
           from table1, table2, table3, etc, etc, etc, etc, etc, 
           where etc etc etc etc etc etc etc etc etc etc etc etc etc"    

# -> "select...\n           from...\n           where..."
      

If single or double quotes are cumbersome because that would need lots of escaping, then the percent string literal notation % is the most flexible solution:

conn.exec %(select attr1, attr2, attr3, attr4, attr5, attr6, attr7
            from table1, table2, table3, etc, etc, etc, etc, etc
            where (ProductLine = 'R' OR ProductLine = "S") AND Country = "...")
# -> "select...\n            from...\n            where..."

If the aim is to avoid the newlines (which both the squiggly HEREDOC, quotes and the percent string literal will cause), then a line continuation can be used by putting a backslash \ as the last non-whitespace character in a line. This will continue the line and will cause Ruby to concatenate the Strings back to back (watch out for those spaces inside the quoted string):

conn.exec 'select attr1, attr2, attr3, attr4, attr5, attr6, attr7 ' \
          'from table1, table2, table3, etc, etc, etc, etc, etc, ' \
          'where etc etc etc etc etc etc etc etc etc etc etc etc etc'

# -> "select...from...where..."

If you use Rails, then String.squish will strip the string of leading and trailing space and collapse all consecutive whitespaces (newlines, tabs, and all) into a single space:

conn.exec "select attr1, attr2, attr3, attr4, attr5, attr6, attr7 
           from table1, table2, table3, etc, etc, etc, etc, etc, 
           where etc etc etc etc etc etc etc etc etc etc etc etc etc".squish

# -> "select...attr7 from...etc, where..."

More details:

Ruby HEREDOC Syntax

The Here Document Notation for Strings is a way to designate long blocks of text inline in code. It is started by << followed by a user-defined String (the End of String terminator). All following lines are concatenated until the End of String terminator is found at the very beginning of a line:

puts <<HEREDOC 
Text Text Text Text
Bla Bla
HEREDOC
# -> "Text Text Text Text\nBlaBla"

The End of String terminator can be chosen freely, but it is common to use something like "EOS" (End of String) or something that matches the domain of the String such as "SQL".

HEREDOC supports interpolation by default or when the EOS terminator is double quoted:

price = 10
print <<"EOS"  # comments can be put here
1.) The price is #{price}.
EOS
# -> "1.) The price is 10."

Interpolation can be disabled if the EOS terminator is single quoted:

print <<'EOS' # Disabled interpolation
3.) The price is #{price}.
EOS
# -> "3.) The price is #{price}."

One important restriction of the <<HEREDOC is that the End of String terminator needs to be at the beginning of the line:

  puts <<EOS 
    def foo
      print "foo"
    end
  EOS
EOS
#-> "....def foo\n......print "foo"\n....end\n..EOS"

To get around this, the <<- syntax was created. It allows the EOS terminator to be indented to make the code look nicer. The lines between the <<- and EOS terminator are still used in their full extend including all indentation:

def printExample
  puts <<-EOS # Use <<- to indent End of String terminator
    def foo
      print "foo"
    end
  EOS
end
# -> "....def foo\n......print "foo"\n....end"

Since Ruby 2.3, we now have the squiggly HEREDOC <<~ removes leading whitespace:

puts <<~EOS # Use the squiggly HEREDOC <<~ to remove leading whitespace (since Ruby 2.3!)
  def foo
    print "foo"
  end
EOS
# -> "def foo\n..print "foo"\nend"

Empty lines and lines which only contains tabs and space are ignored by <<~

puts <<~EOS.inspect 
  Hello

    World!
EOS
#-> "Hello\n..World!"

If both tabs and spaces are used, tabs are considered as equal to 8 spaces. If the least-indented line is in the middle of a tab, this tab is not removed.

puts <<~EOS.inspect
<tab>One Tab
<space><space>Two Spaces
EOS
# -> "\tOne Tab\nTwoSpaces"

HEREDOC can do some crazy stuff such as executing commands using backticks:

puts <<`EOC`            
echo #{price}
echo #{price * 2}
EOC

HEREDOC String definitions can be "stacked", which means that the first EOS terminator (EOSFOO below) will end the first string and start the second (EOSBAR below):

print <<EOSFOO, <<EOSBAR    # you can stack them
I said foo.
EOSFOO
I said bar.
EOSBAR

I don't think anybody would ever use it as such, but the <<EOS is really just a string literal and can be put whereever a string can normally be put:

def func(a,b,c)
  puts a
  puts b
  puts c
end

func(<<THIS, 23, <<THAT) 
Here's a line
or two.
THIS
and here's another.
THAT

If you don't have Ruby 2.3, but Rails >= 3.0 then you can use String.strip_heredoc which does the same as <<~

# File activesupport/lib/active_support/core_ext/string/strip.rb, line 22
class String
  def strip_heredoc
    gsub(/^#{scan(/^[ \t]*(?=\S)/).min}/, "".freeze)
  end
end

puts <<-USAGE.strip_heredoc # If no Ruby 2.3, but Rails >= 3.0
  This command does such and such.

  Supported options are:
    -h         This message
    ...
USAGE

Troubleshooting

If you see errors when Ruby parses your file, then it is most likely that you either have extra leading or trailing spaces with a HEREDOC or extra trailing spaces with a squiggly HEREDOC. For example:

What you see:

    database_yml = <<~EOS
      production:
        database: #{fetch(:user)}
        adapter: postgresql
        pool: 5
        timeout: 5000
    EOS  

What Ruby tells you:

SyntaxError: .../sample.rb:xx: can't find string "EOS" anywhere before EOF
...sample.rb:xx: syntax error, unexpected end-of-input, expecting `end'

What is at fault:

Spot the extra spaces after the terminating EOS.

Percent String Literals

See RubyDoc for how to use the percentage sign followed by a string in a parentheses pair such as a %(...), %[...], %{...}, etc. or a pair of any non-alphanumeric character such as %+...+

Last Words

Last, to get the answer to the original question "Is there a way to imply concatenation?" answered: Ruby always implies concatenation if two strings (single and double quoted) are found back to back:

puts "select..." 'from table...' "where..."
# -> "select...from table...where..."

The caveat is that this does not work across line-breaks, because Ruby is interpreting an end of statement and the consequitive line of just strings alone on a line doesn't do anything.

2015 Answer: CSS last-of-type allows you to style the last item.

ul li:last-of-type { color: red; }

For python 3

import datetime
now = datetime.datetime.now()
print(now.year, now.month, now.day, now.hour, now.minute, now.second)

The accepted answer is good, but it can be greatly improved by additionally backing up on every save and backing up versioned files.

First, basic settings as described in the accepted answer:

(setq version-control t     ;; Use version numbers for backups.
      kept-new-versions 10  ;; Number of newest versions to keep.
      kept-old-versions 0   ;; Number of oldest versions to keep.
      delete-old-versions t ;; Don't ask to delete excess backup versions.
      backup-by-copying t)  ;; Copy all files, don't rename them.

Next, also backup versioned files, which Emacs does not do by default (you don't commit on every save, right?):

(setq vc-make-backup-files t)

Finally, make a backup on each save, not just the first. We make two kinds of backups:

1. per-session backups: once on the first save of the buffer in each Emacs session. These simulate Emac's default backup behavior.

2. per-save backups: once on every save. Emacs does not do this by default, but it's very useful if you leave Emacs running for a long time.

The backups go in different places and Emacs creates the backup dirs automatically if they don't exist:

;; Default and per-save backups go here:
(setq backup-directory-alist '(("" . "~/.emacs.d/backup/per-save")))

(defun force-backup-of-buffer ()
  ;; Make a special "per session" backup at the first save of each
  ;; emacs session.
  (when (not buffer-backed-up)
    ;; Override the default parameters for per-session backups.
    (let ((backup-directory-alist '(("" . "~/.emacs.d/backup/per-session")))
          (kept-new-versions 3))
      (backup-buffer)))
  ;; Make a "per save" backup on each save.  The first save results in
  ;; both a per-session and a per-save backup, to keep the numbering
  ;; of per-save backups consistent.
  (let ((buffer-backed-up nil))
    (backup-buffer)))

(add-hook 'before-save-hook  'force-backup-of-buffer)

I became very interested in this topic after I wrote $< instead of $@ in my Makefile, about three hours after my previous commit :P

The above is based on an Emacs Wiki page I heavily edited.

string = 'http://www.domain.com/?s=some&two=20'
cut_string = string.split('&')
new_string = cut_string[0]
print(new_string)

Here is my alternative. It is object-oriented and is more like mysql/mysqli things.

class MMySqliStmt{
    private $stmt;
    private $row;

    public function __construct($stmt){
        $this->stmt = $stmt;
        $md = $stmt->result_metadata();
        $params = array();
        while($field = $md->fetch_field()) {
            $params[] = &$this->row[$field->name];
        }
        call_user_func_array(array($stmt, 'bind_result'), $params) or die('Sql Error');
    }

    public function fetch_array(){
        if($this->stmt->fetch()){
            $result = array();
            foreach($this->row as $k => $v){
                $result[$k] = $v;
            }
            return $result;
        }else{
            return false;
        }
    }

    public function free(){
        $this->stmt->close();
    }
}

Usage:

$stmt = $conn->prepare($str);
//...bind_param... and so on
if(!$stmt->execute())die('Mysql Query(Execute) Error : '.$str);
$result = new MMySqliStmt($stmt);
while($row = $result->fetch_array()){
    array_push($arr, $row);
    //for example, use $row['id']
}
$result->free();
//for example, use the $arr

You can hit the key q (for quit) and it should take you to the prompt.

The configuration here is working for me:

configurations {
    customProvidedRuntime
}

dependencies {
    compile(
        // Spring Boot dependencies
    )

    customProvidedRuntime('org.springframework.boot:spring-boot-starter-tomcat')
}

war {
    classpath = files(configurations.runtime.minus(configurations.customProvidedRuntime))
}

springBoot {
    providedConfiguration = "customProvidedRuntime"
}

I found the simplest solution is to add two registry entries as follows (run this in a command prompt with admin privileges):

reg add HKLM\SOFTWARE\Microsoft\.NETFramework\v4.0.30319 /v SchUseStrongCrypto /t REG_DWORD /d 1 /reg:32

reg add HKLM\SOFTWARE\Microsoft\.NETFramework\v4.0.30319 /v SchUseStrongCrypto /t REG_DWORD /d 1 /reg:64

These entries seem to affect how the .NET CLR chooses a protocol when making a secure connection as a client.

There is more information about this registry entry here:

https://docs.microsoft.com/en-us/security-updates/SecurityAdvisories/2015/2960358#suggested-actions

Not only is this simpler, but assuming it works for your case, far more robust than a code-based solution, which requires developers to track protocol and development and update all their relevant code. Hopefully, similar environment changes can be made for TLS 1.3 and beyond, as long as .NET remains dumb enough to not automatically choose the highest available protocol.

NOTE: Even though, according to the article above, this is only supposed to disable RC4, and one would not think this would change whether the .NET client is allowed to use TLS1.2+ or not, for some reason it does have this effect.

NOTE: As noted by @Jordan Rieger in the comments, this is not a solution for POODLE, since it does not disable the older protocols a -- it merely allows the client to work with newer protocols e.g. when a patched server has disabled the older protocols. However, with a MITM attack, obviously a compromised server will offer the client an older protocol, which the client will then happily use.

TODO: Try to disable client-side use of TLS1.0 and TLS1.1 with these registry entries, however I don't know if the .NET http client libraries respect these settings or not:

https://docs.microsoft.com/en-us/windows-server/security/tls/tls-registry-settings#tls-10

https://docs.microsoft.com/en-us/windows-server/security/tls/tls-registry-settings#tls-11

Send file as binary content (upload without form or FormData)

In the given answers/examples the file is (most likely) uploaded with a HTML form or using the FormData API. The file is only a part of the data sent in the request, hence the multipart/form-data Content-Type header.

If you want to send the file as the only content then you can directly add it as the request body and you set the Content-Type header to the MIME type of the file you are sending. The file name can be added in the Content-Disposition header. You can upload like this:

var xmlHttpRequest = new XMLHttpRequest();

var file = ...file handle...
var fileName = ...file name...
var target = ...target...
var mimeType = ...mime type...

xmlHttpRequest.open('POST', target, true);
xmlHttpRequest.setRequestHeader('Content-Type', mimeType);
xmlHttpRequest.setRequestHeader('Content-Disposition', 'attachment; filename="' + fileName + '"');
xmlHttpRequest.send(file);

If you don't (want to) use forms and you are only interested in uploading one single file this is the easiest way to include your file in the request.

After you follow the first response, you can run your app using

react-native run-android --variant=debug

And your app will run without need for the packager

I think you are looking for print_r which will print out the array as text. You can't control the formatting though, it's more for debugging. If you want cool formatting you'll need to do it manually.

If you are after performance, try to avoid using AngularJS filters as they are applied twice per each expression to check for their stability.

A better way would be to use CSS ::first-letter pseudo-element with text-transform: uppercase;. That can't be used on inline elements such as span, though, so the next best thing would be to use text-transform: capitalize; on the whole block, which capitalizes every word.

Example:

var app = angular.module('app', []);_x000D_
_x000D_
app.controller('Ctrl', function ($scope) {_x000D_
   $scope.msg = 'hello, world.';_x000D_
});

.capitalize {_x000D_
  display: inline-block;  _x000D_
}_x000D_
_x000D_
.capitalize::first-letter {_x000D_
  text-transform: uppercase;_x000D_
}_x000D_
_x000D_
.capitalize2 {_x000D_
  text-transform: capitalize;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>_x000D_
<div ng-app="app">_x000D_
    <div ng-controller="Ctrl">_x000D_
        <b>My text:</b> <div class="capitalize">{{msg}}</div>_x000D_
        <p><b>My text:</b> <span class="capitalize2">{{msg}}</span></p>_x000D_
    </div>_x000D_
</div>

                .allowCredentials(true)
                .maxAge(4800);
    }
}

I had to modify the Security configuration also like below:

        @Override
        protected void configure(HttpSecurity http) throws Exception {
            http.csrf().disable()
                    .cors().configurationSource(new CorsConfigurationSource() {

                @Override
                public CorsConfiguration getCorsConfiguration(HttpServletRequest request) {
                    CorsConfiguration config = new CorsConfiguration();
                    config.setAllowedHeaders(Collections.singletonList("*"));
                    config.setAllowedMethods(Collections.singletonList("*"));
                    config.addAllowedOrigin("*");
                    config.setAllowCredentials(true);
                    return config;
                }
            }).and()
                    .antMatcher("/api/**")
                    .authorizeRequests()
                    .anyRequest().authenticated()
                    .and().httpBasic()
                    .and().sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS)
                    .and().exceptionHandling().accessDeniedHandler(apiAccessDeniedHandler());
        }

When you call "https://darkorbit.com/" your server figures that it's missing "www" so it redirects the call to "http://www.darkorbit.com/" and then to "https://www.darkorbit.com/", your WebView call is blocked at the first redirection as it's a "http" call. You can call "https://www.darkorbit.com/" instead and it will solve the issue.

A closure is something many JavaScript developers use all the time, but we take it for granted. How it works is not that complicated. Understanding how to use it purposefully is complex.

At its simplest definition (as other answers have pointed out), a closure is basically a function defined inside another function. And that inner function has access to variables defined in the scope of the outer function. The most common practice that you'll see using closures is defining variables and functions in the global scope, and having access to those variables in the function scope of that function.

var x = 1;
function myFN() {
  alert(x); //1, as opposed to undefined.
}
// Or
function a() {
   var x = 1;
   function b() {
       alert(x); //1, as opposed to undefined.
   }
   b();
}

So what?

A closure isn't that special to a JavaScript user until you think about what life would be like without them. In other languages, variables used in a function get cleaned up when that function returns. In the above, x would have been a "null pointer", and you'd need to establish a getter and setter and start passing references. Doesn't sound like JavaScript right? Thank the mighty closure.

Why should I care?

You don't really have to be aware of closures to use them. But as others have also pointed out, they can be leveraged to create faux private variables. Until you get to needing private variables, just use them like you always have.

Here are three ways to parse strings into integers, from fastest runtime to slowest:

1. strconv.ParseInt(...) fastest
2. strconv.Atoi(...) still very fast
3. fmt.Sscanf(...) not terribly fast but most flexible

Here's a benchmark that shows usage and example timing for each function:

package main

import "fmt"
import "strconv"
import "testing"

var num = 123456
var numstr = "123456"

func BenchmarkStrconvParseInt(b *testing.B) {
  num64 := int64(num)
  for i := 0; i < b.N; i++ {
    x, err := strconv.ParseInt(numstr, 10, 64)
    if x != num64 || err != nil {
      b.Error(err)
    }
  }
}

func BenchmarkAtoi(b *testing.B) {
  for i := 0; i < b.N; i++ {
    x, err := strconv.Atoi(numstr)
    if x != num || err != nil {
      b.Error(err)
    }
  }
}

func BenchmarkFmtSscan(b *testing.B) {
  for i := 0; i < b.N; i++ {
    var x int
    n, err := fmt.Sscanf(numstr, "%d", &x)
    if n != 1 || x != num || err != nil {
      b.Error(err)
    }
  }
}

You can run it by saving as atoi_test.go and running go test -bench=. atoi_test.go.

If you want to make your statement easily readable, then you can use REGEXP_LIKE (available from Oracle version 10 onwards).

An example table:

SQL> create table mytable (something)
  2  as
  3  select 'blabla' from dual union all
  4  select 'notbla' from dual union all
  5  select 'ofooof' from dual union all
  6  select 'ofofof' from dual union all
  7  select 'batzzz' from dual
  8  /

Table created.

The original syntax:

SQL> select something
  2    from mytable
  3   where something like 'bla%'
  4      or something like '%foo%'
  5      or something like 'batz%'
  6  /

SOMETH
------
blabla
ofooof
batzzz

3 rows selected.

And a simple looking query with REGEXP_LIKE

SQL> select something
  2    from mytable
  3   where regexp_like (something,'^bla|foo|^batz')
  4  /

SOMETH
------
blabla
ofooof
batzzz

I would not recommend it myself due to the not-so-good performance. I'd stick with the several LIKE predicates. So the examples were just for fun.

You're looking for JSON.stringify().

To go one step further, you could declare a type pointer to a function signature like:

interface myCallbackType { (myArgument: string): void }

and use it like this:

public myCallback : myCallbackType;

Filter: - A filter as the name suggests is a Java class executed by the servlet container for each incoming HTTP request and for each http response. This way, is possible to manage HTTP incoming requests before them reach the resource, such as a JSP page, a servlet or a simple static page; in the same way is possible to manage HTTP outbound response after resource execution.

Interceptor: - Spring Interceptors are similar to Servlet Filters but they acts in Spring Context so are many powerful to manage HTTP Request and Response but they can implement more sophisticated behavior because can access to all Spring context.

When you visited https://localhost previously at some point it not only visited this over a secure channel (https rather than http), it also told your browser, using a special HTTP header: Strict-Transport-Security (often abbreviated to HSTS), that it should ONLY use https for all future visits.

This is a security feature web servers can use to prevent people being downgraded to http (either intentionally or by some evil party).

However if you then then turn off your https server, and just want to browse http you can't (by design - that's the point of this security feature).

HSTS also does prevents you from accepting and skipping past certificate errors.

To reset this, so HSTS is no longer set for localhost, type the following in your Chrome address bar:

chrome://net-internals/#hsts

Where you will be able to delete this setting for "localhost".

You might also want to find out what was setting this to avoid this problem in future!

Note that for other sites (e.g. www.google.com) these are "preloaded" into the Chrome code and so cannot be removed. When you query them at chrome://net-internals/#hsts you will see them listed as static HSTS entries.

And finally note that Google has started preloading HSTS for the entire .dev domain: https://ma.ttias.be/chrome-force-dev-domains-https-via-preloaded-hsts/

Here is one simple PHP Script which gets exchange rate between GBP and USD

<?php
$amount = urlencode("1");
$from_GBP0 = urlencode("GBP");
$to_usd= urlencode("USD");
$Dallor = "hl=en&q=$amount$from_GBP0%3D%3F$to_usd";
$US_Rate = file_get_contents("http://google.com/ig/calculator?".$Dallor);
$US_data = explode('"', $US_Rate);
$US_data = explode(' ', $US_data['3']);
$var_USD = $US_data['0'];
echo $to_usd;
echo $var_USD;
echo '<br/>'; 
?>

You can bind resize using .resize() and run your code when the browser is resized. You need to also add an else condition to your if statement so that your css values toggle the old and the new, rather than just setting the new.

First, ensure that /dev/ttyUSB0 works. E.g. plug in mouse and check it works. Second, try select other board. It is often that non-original boards do not recognized correctly under their names. Third, try press reset button manually while uploading sketch. Probably automatic reset is broken.

Try this:

$results = DB::table('users')->toSql();
dd($results);

Note: get() has been replaced with toSql() to display the raw SQL query.

I wrote a library which makes working with json data and deserialization a breeze in Swift. You can get it here: https://github.com/isair/JSONHelper

Edit: I updated my library, you can now do it with just this:

class Business: Deserializable {
    var id: Int?
    var name = "N/A"  // This one has a default value.

    required init(data: [String: AnyObject]) {
        id <-- data["id"]
        name <-- data["name"]
    }
}

var businesses: [Business]()

Alamofire.request(.GET, "http://MyWebService/").responseString { (request, response, string, error) in
    businesses <-- string
}

Old Answer:

First, instead of using .responseString, use .response to get a response object. Then change your code to:

func getAllBusinesses() {

    Alamofire.request(.GET, "http://MyWebService/").response { (request, response, data, error) in
        var businesses: [Business]?

        businesses <-- data

        if businesses == nil {
            // Data was not structured as expected and deserialization failed, do something.
        } else {
            // Do something with your businesses array. 
        }
    }
}

And you need to make a Business class like this:

class Business: Deserializable {
    var id: Int?
    var name = "N/A"  // This one has a default value.

    required init(data: [String: AnyObject]) {
        id <-- data["id"]
        name <-- data["name"]
    }
}

Windows has two different settings in which priority is established. There is the metric value which you have already set in the adapter settings, and then there is the connection priority in the network connections settings.

To change the priority of the connections:

• Open your Adapter Settings (Control Panel\Network and Internet\Network Connections)
• Click Alt to pull up the menu bar
• Select Advanced -> Advanced Settings
• Change the order of the connections so that the connection you want to have priority is top on the list

I would check them one-by-one; i.e. look for a number \d+, then if that fails you can tell the user they need to add a digit. This avoids returning an "Invalid" error without hinting to the user whats wrong with it.

The shortest:

command || exit /b

If you need, you can set the exit code:

command || exit /b 666

And you can also log:

command || echo ERROR && exit /b

If you are into performance, then it is worth using ENUM type. It will probably be faster on big tables, due to the better index performance.

The way of using it (source: http://dev.mysql.com/doc/refman/5.5/en/enum.html):

CREATE TABLE shirts (
    name VARCHAR(40),
    size ENUM('x-small', 'small', 'medium', 'large', 'x-large')
);

But, I always say that explaining the query like this:

EXPLAIN SELECT * FROM shirts WHERE size='medium';

will tell you lots of information about your query and help on building a better table structure. For this end, it is usefull to let phpmyadmin Propose a table table structure - but this is more a long time optimisation possibility, when the table is already filled with lots of data.

A lot of other answers are focusing on a pattern that does work, but their explanations aren't really very thorough as to why your current code doesn't work.

Your code, for reference:

function funcName() {
    alert("test");
}

var func = funcName();
var run = setInterval("func",10000)

Let's break this up into chunks. Your function funcName is fine. Note that when you call funcName (in other words, you run it) you will be alerting "test". But notice that funcName() -- the parentheses mean to "call" or "run" the function -- doesn't actually return a value. When a function doesn't have a return value, it defaults to a value known as undefined.

When you call a function, you append its argument list to the end in parentheses. When you don't have any arguments to pass the function, you just add empty parentheses, like funcName(). But when you want to refer to the function itself, and not call it, you don't need the parentheses because the parentheses indicate to run it.

So, when you say:

var func = funcName();

You are actually declaring a variable func that has a value of funcName(). But notice the parentheses. funcName() is actually the return value of funcName. As I said above, since funcName doesn't actually return any value, it defaults to undefined. So, in other words, your variable func actually will have the value undefined.

Then you have this line:

var run = setInterval("func",10000)

The function setInterval takes two arguments. The first is the function to be ran every so often, and the second is the number of milliseconds between each time the function is ran.

However, the first argument really should be a function, not a string. If it is a string, then the JavaScript engine will use eval on that string instead. So, in other words, your setInterval is running the following JavaScript code:

func
// 10 seconds later....
func
// and so on

However, func is just a variable (with the value undefined, but that's sort of irrelevant). So every ten seconds, the JS engine evaluates the variable func and returns undefined. But this doesn't really do anything. I mean, it technically is being evaluated every 10 seconds, but you're not going to see any effects from that.

The solution is to give setInterval a function to run instead of a string. So, in this case:

var run = setInterval(funcName, 10000);

Notice that I didn't give it func. This is because func is not a function in your code; it's the value undefined, because you assigned it funcName(). Like I said above, funcName() will call the function funcName and return the return value of the function. Since funcName doesn't return anything, this defaults to undefined. I know I've said that several times now, but it really is a very important concept: when you see funcName(), you should think "the return value of funcName". When you want to refer to a function itself, like a separate entity, you should leave off the parentheses so you don't call it: funcName.

So, another solution for your code would be:

var func = funcName;
var run = setInterval(func, 10000);

However, that's a bit redundant: why use func instead of funcName?

Or you can stay as true as possible to the original code by modifying two bits:

var func = funcName;
var run = setInterval("func()", 10000);

In this case, the JS engine will evaluate func() every ten seconds. In other words, it will alert "test" every ten seconds. However, as the famous phrase goes, eval is evil, so you should try to avoid it whenever possible.

Another twist on this code is to use an anonymous function. In other words, a function that doesn't have a name -- you just drop it in the code because you don't care what it's called.

setInterval(function () {
    alert("test");
}, 10000);

In this case, since I don't care what the function is called, I just leave a generic, unnamed (anonymous) function there.

Use

var jsDate = $('#your_datepicker_id').datepicker('getDate');
if (jsDate !== null) { // if any date selected in datepicker
    jsDate instanceof Date; // -> true
    jsDate.getDate();
    jsDate.getMonth();
    jsDate.getFullYear();
}

If you start out with:

let array = [
    {name: "malcom", dogType: "four-legged"},
    {name: "peabody", dogType: "three-legged"},
    {name: "pablo", dogType: "two-legged"}
];

And you want a set of, say, names, you would do:

let namesSet = new Set(array.map(item => item.name));

Additional data (in case you have more questions):

FOO: {
       for my $i ( @listone ){
          for my $j ( @listtwo ){
                 if ( cond( $i,$j ) ){

                    last FOO;  # --->
                                   # |
                 }                 # |
          }                        # |
       }                           # |

The picture you showd in the question is actually a chart made using JavaScript. It is actually very easy to plot multi-axis chart using JavaScript with the help of 3rd party libraries like HighChart.js or D3.js. Here I propose to use the Funfun Excel add-in which allows you to use JavaScript directly in Excel so you could plot chart like you've showed easily in Excel. Here I made an example using Funfun in Excel.

You could see in this chart you have one axis of Rainfall at the left side while two axis of Temperature and Sea-pressure level at the right side. This is also a combination of line chart and bar chart for different datasets. In this example, with the help of the Funfun add-in, I used HighChart.js to plot this chart.

Funfun also has an online editor in which you could test your JavaScript code with you data. You could check the detailed code of this example on the link below.

https://www.funfun.io/1/#/edit/5a43b416b848f771fbcdee2c

Edit: The content on the previous link has been changed so I posted a new link here. The link below is the original link https://www.funfun.io/1/#/edit/5a55dc978dfd67466879eb24

If you are satisfied with the result you achieved in the online editor, you could easily load the result into you Excel using the URL above. Of couse first you need to insert the Funfun add-in from Insert - My add-ins. Here are some screenshots showing how you could do this.

Disclosure: I'm a developer of Funfun

// store the startTime prop in local state
const [startTime, setStartTime] = useState(props.startTime)
// 
useEffect(() => {
  if (props.startTime !== startTime) {
    setStartTime(props.startTime);
  }
}, [props.startTime]);

Can this method be migrated to class components?

The system stored procedure sp_help will give you the information. Execute the following statement:

execute sp_help table_name

Sometimes it's knowing what to ask. I didn't know as I am a developer who has taken on some DevOps work.

Apparently 'passwordless' or NOPASSWD login is a thing which you need to put in the /etc/sudoers file.

The answer to my question is at Ansible: best practice for maintaining list of sudoers.

The Ansible playbook code fragment looks like this from my problem:

- name: Make sure we have a 'wheel' group
  group:
    name: wheel
    state: present

- name: Allow 'wheel' group to have passwordless sudo
  lineinfile:
    dest: /etc/sudoers
    state: present
    regexp: '^%wheel'
    line: '%wheel ALL=(ALL) NOPASSWD: ALL'
    validate: 'visudo -cf %s'

- name: Add sudoers users to wheel group
  user:
    name=deployer
    groups=wheel
    append=yes
    state=present
    createhome=yes

- name: Set up authorized keys for the deployer user
  authorized_key: user=deployer key="{{item}}"
  with_file:
    - /home/railsdev/.ssh/id_rsa.pub

And the best part is that the solution is idempotent. It doesn't add the line

%wheel ALL=(ALL) NOPASSWD: ALL

to /etc/sudoers when the playbook is run a subsequent time. And yes...I was able to ssh into the server as "deployer" and run sudo commands without having to give a password.

Something like this would work

/^\d{2}$/

you can also copy your JRE folder to eclipse directory and it will work corectly

Go to your Project properties (Project -> Properties -> Configuration Properties -> C/C++ -> General) and in the field Additional Include Directories add the path to your .h file.

And be sure that your Configuration and Platform are the active ones. Example: Configuration: Active(Debug) Platform: Active(Win32).

function myFunction() {
  var sheetname = "DateEntry";//Sheet where you want to put the date
  var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName(sheetname);
    // You could use now Date(); on its own but it will not look nice.
  var date = Utilities.formatDate(new Date(), "GMT+5:30", "yyyy-MM-dd");
    //var endDate = date;
    sheet.getRange(sheet.getLastRow() + 1,1).setValue(date); //Gets the last row which had value, and goes to the next empty row to put new values.
}

Why do we use:

1) cin.ignore

2) cin.clear

?

Simply:

1) To ignore (extract and discard) values that we don't want on the stream

2) To clear the internal state of stream. After using cin.clear internal state is set again back to goodbit, which means that there are no 'errors'.

Long version:

If something is put on 'stream' (cin) then it must be taken from there. By 'taken' we mean 'used', 'removed', 'extracted' from stream. Stream has a flow. The data is flowing on cin like water on stream. You simply cannot stop the flow of water ;)

Look at the example:

string name; //line 1
cout << "Give me your name and surname:"<<endl;//line 2
cin >> name;//line 3
int age;//line 4
cout << "Give me your age:" <<endl;//line 5
cin >> age;//line 6

What happens if the user answers: "Arkadiusz Wlodarczyk" for first question?

Run the program to see for yourself.

You will see on console "Arkadiusz" but program won't ask you for 'age'. It will just finish immediately right after printing "Arkadiusz".

And "Wlodarczyk" is not shown. It seems like if it was gone (?)*

What happened? ;-)

Because there is a space between "Arkadiusz" and "Wlodarczyk".

"space" character between the name and surname is a sign for computer that there are two variables waiting to be extracted on 'input' stream.

The computer thinks that you are tying to send to input more than one variable. That "space" sign is a sign for him to interpret it that way.

So computer assigns "Arkadiusz" to 'name' (2) and because you put more than one string on stream (input) computer will try to assign value "Wlodarczyk" to variable 'age' (!). The user won't have a chance to put anything on the 'cin' in line 6 because that instruction was already executed(!). Why? Because there was still something left on stream. And as I said earlier stream is in a flow so everything must be removed from it as soon as possible. And the possibility came when computer saw instruction cin >> age;

Computer doesn't know that you created a variable that stores age of somebody (line 4). 'age' is merely a label. For computer 'age' could be as well called: 'afsfasgfsagasggas' and it would be the same. For him it's just a variable that he will try to assign "Wlodarczyk" to because you ordered/instructed computer to do so in line (6).

It's wrong to do so, but hey it's you who did it! It's your fault! Well, maybe user, but still...

All right all right. But how to fix it?!

Let's try to play with that example a bit before we fix it properly to learn a few more interesting things :-)

I prefer to make an approach where we understand things. Fixing something without knowledge how we did it doesn't give satisfaction, don't you think? :)

string name;
cout << "Give me your name and surname:"<<endl;
cin >> name;
int age;
cout << "Give me your age:" <<endl;
cin >> age;
cout << cin.rdstate(); //new line is here :-)

After invoking above code you will notice that the state of your stream (cin) is equal to 4 (line 7). Which means its internal state is no longer equal to goodbit. Something is messed up. It's pretty obvious, isn't it? You tried to assign string type value ("Wlodarczyk") to int type variable 'age'. Types doesn't match. It's time to inform that something is wrong. And computer does it by changing internal state of stream. It's like: "You f**** up man, fix me please. I inform you 'kindly' ;-)"

You simply cannot use 'cin' (stream) anymore. It's stuck. Like if you had put big wood logs on water stream. You must fix it before you can use it. Data (water) cannot be obtained from that stream(cin) anymore because log of wood (internal state) doesn't allow you to do so.

Oh so if there is an obstacle (wood logs) we can just remove it using tools that is made to do so?

Yes!

internal state of cin set to 4 is like an alarm that is howling and making noise.

cin.clear clears the state back to normal (goodbit). It's like if you had come and silenced the alarm. You just put it off. You know something happened so you say: "It's OK to stop making noise, I know something is wrong already, shut up (clear)".

All right let's do so! Let's use cin.clear().

Invoke below code using "Arkadiusz Wlodarczyk" as first input:

string name;
cout << "Give me your name and surname:"<<endl;
cin >> name;
int age;
cout << "Give me your age:" <<endl;
cin >> age;
cout << cin.rdstate() << endl; 
cin.clear(); //new line is here :-)
cout << cin.rdstate()<< endl;  //new line is here :-)

We can surely see after executing above code that the state is equal to goodbit.

Great so the problem is solved?

Invoke below code using "Arkadiusz Wlodarczyk" as first input:

string name;
cout << "Give me your name and surname:"<<endl;
cin >> name;
int age;
cout << "Give me your age:" <<endl;
cin >> age;
cout << cin.rdstate() << endl;; 
cin.clear(); 
cout << cin.rdstate() << endl; 
cin >> age;//new line is here :-)

Even tho the state is set to goodbit after line 9 the user is not asked for "age". The program stops.

WHY?!

Oh man... You've just put off alarm, what about the wood log inside a water?* Go back to text where we talked about "Wlodarczyk" how it supposedly was gone.

You need to remove "Wlodarczyk" that piece of wood from stream. Turning off alarms doesn't solve the problem at all. You've just silenced it and you think the problem is gone? ;)

So it's time for another tool:

cin.ignore can be compared to a special truck with ropes that comes and removes the wood logs that got the stream stuck. It clears the problem the user of your program created.

So could we use it even before making the alarm goes off?

Yes:

string name;
cout << "Give me your name and surname:"<< endl;
cin >> name;
cin.ignore(10000, '\n'); //time to remove "Wlodarczyk" the wood log and make the stream flow
int age;
cout << "Give me your age:" << endl;
cin >> age;

The "Wlodarczyk" is gonna be removed before making the noise in line 7.

What is 10000 and '\n'?

It says remove 10000 characters (just in case) until '\n' is met (ENTER). BTW It can be done better using numeric_limits but it's not the topic of this answer.

So the main cause of problem is gone before noise was made...

Why do we need 'clear' then?

What if someone had asked for 'give me your age' question in line 6 for example: "twenty years old" instead of writing 20?

Types doesn't match again. Computer tries to assign string to int. And alarm starts. You don't have a chance to even react on situation like that. cin.ignore won't help you in case like that.

So we must use clear in case like that:

string name;
cout << "Give me your name and surname:"<< endl;
cin >> name;
cin.ignore(10000, '\n'); //time to remove "Wlodarczyk" the wood log and make the stream flow
int age;
cout << "Give me your age:" << endl;
cin >> age;
cin.clear();
cin.ignore(10000, '\n'); //time to remove "Wlodarczyk" the wood log and make the stream flow

But should you clear the state 'just in case'?

Of course not.

If something goes wrong (cin >> age;) instruction is gonna inform you about it by returning false.

So we can use conditional statement to check if the user put wrong type on the stream

int age;
if (cin >> age) //it's gonna return false if types doesn't match
    cout << "You put integer";
else
    cout << "You bad boy! it was supposed to be int";

All right so we can fix our initial problem like for example that:

string name;
cout << "Give me your name and surname:"<< endl;
cin >> name;
cin.ignore(10000, '\n'); //time to remove "Wlodarczyk" the wood log and make the stream flow

int age;
cout << "Give me your age:" << endl;
if (cin >> age)
  cout << "Your age is equal to:" << endl;
else
{
 cin.clear();
 cin.ignore(10000, '\n'); //time to remove "Wlodarczyk" the wood log and make the stream flow
 cout << "Give me your age name as string I dare you";
 cin >> age;
}

Of course this can be improved by for example doing what you did in question using loop while.

BONUS:

You might be wondering. What about if I wanted to get name and surname in the same line from the user? Is it even possible using cin if cin interprets each value separated by "space" as different variable?

Sure, you can do it two ways:

1)

string name, surname;
cout << "Give me your name and surname:"<< endl;
cin >> name;
cin >> surname;

cout << "Hello, " << name << " " << surname << endl;

2) or by using getline function.

getline(cin, nameOfStringVariable);

and that's how to do it:

string nameAndSurname;
cout << "Give me your name and surname:"<< endl;
getline(cin, nameAndSurname);

cout << "Hello, " << nameAndSurname << endl;

The second option might backfire you in case you use it after you use 'cin' before the getline.

Let's check it out:

a)

int age;
cout << "Give me your age:" <<endl;
cin >> age;
cout << "Your age is" << age << endl;

string nameAndSurname;
cout << "Give me your name and surname:"<< endl;
getline(cin, nameAndSurname);

cout << "Hello, " << nameAndSurname << endl;

If you put "20" as age you won't be asked for nameAndSurname.

But if you do it that way:

b)

string nameAndSurname;
cout << "Give me your name and surname:"<< endl;
getline(cin, nameAndSurname);

cout << "Hello, " << nameAndSurname << endl;
int age;
cout << "Give me your age:" <<endl;
cin >> age;
cout << "Your age is" << age << endll

everything is fine.

WHAT?!

Every time you put something on input (stream) you leave at the end white character which is ENTER ('\n') You have to somehow enter values to console. So it must happen if the data comes from user.

b) cin characteristics is that it ignores whitespace, so when you are reading in information from cin, the newline character '\n' doesn't matter. It gets ignored.

a) getline function gets the entire line up to the newline character ('\n'), and when the newline char is the first thing the getline function gets '\n', and that's all to get. You extract newline character that was left on stream by user who put "20" on stream in line 3.

So in order to fix it is to always invoke cin.ignore(); each time you use cin to get any value if you are ever going to use getline() inside your program.

So the proper code would be:

int age;
cout << "Give me your age:" <<endl;
cin >> age;
cin.ignore(); // it ignores just enter without arguments being sent. it's same as cin.ignore(1, '\n') 
cout << "Your age is" << age << endl;


string nameAndSurname;
cout << "Give me your name and surname:"<< endl;
getline(cin, nameAndSurname);

cout << "Hello, " << nameAndSurname << endl;

I hope streams are more clear to you know.

Hah silence me please! :-)

With gitk you can view the two branches graphically:

And then it's easy to find the common ancestor in the history of the two branches.

If this code is on a separate project, like a library project. Don't forgeet to add reference to system.configuration.

Using setOnItemClickListener is the correct answer, but if you have a keyboard you can change selection even with arrows (no click is performed), so, you need to implement also setOnItemSelectedListener :

myListView.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
            @Override
            public void onItemSelected(AdapterView<?> adapterView, View view, int position, long l) {
     MyObject tmp=(MyObject) adapterView.getItemAtPosition(position);
         }
            @Override
            public void onNothingSelected(AdapterView<?> adapterView) {
                // your stuff
            }
        });

Setting widths explicitly using sWidth for each column AND bAutoWidth: false in dataTable initialization solved my (similar) problem. Love the overflowing stack.

You must be separate those classes which you want to remove by white space$('selector').removeClass('class1 class2');

According to the documentation NUM_ROWS is the "Number of rows in the table", so I can see how this might be confusing. There, however, is a major difference between these two methods.

This query selects the number of rows in MY_TABLE from a system view. This is data that Oracle has previously collected and stored.

select num_rows from all_tables where table_name = 'MY_TABLE'

This query counts the current number of rows in MY_TABLE

select count(*) from my_table

By definition they are difference pieces of data. There are two additional pieces of information you need about NUM_ROWS.

1. In the documentation there's an asterisk by the column name, which leads to this note:

   Columns marked with an asterisk (*) are populated only if you collect statistics on the table with the ANALYZE statement or the DBMS_STATS package.

   This means that unless you have gathered statistics on the table then this column will not have any data.

2. Statistics gathered in 11g+ with the default estimate_percent, or with a 100% estimate, will return an accurate number for that point in time. But statistics gathered before 11g, or with a custom estimate_percent less than 100%, uses dynamic sampling and may be incorrect. If you gather 99.999% a single row may be missed, which in turn means that the answer you get is incorrect.

If your table is never updated then it is certainly possible to use ALL_TABLES.NUM_ROWS to find out the number of rows in a table. However, and it's a big however, if any process inserts or deletes rows from your table it will be at best a good approximation and depending on whether your database gathers statistics automatically could be horribly wrong.

Generally speaking, it is always better to actually count the number of rows in the table rather then relying on the system tables.

If you're using data binding, then you need to use the ContentRendered event.

For the code below, the Header is NULL when the Loaded event is raised. However, Header gets its value when the ContentRendered event is raised.

<MenuItem Header="{Binding NewGame_Name}" Command="{Binding NewGameCommand}" />

---
- hosts: all
  tasks:
  - name: Gather Version
    debug:
     msg: "The server Operating system is {{ ansible_distribution }} {{ ansible_distribution_major_version }}"
  - name: Write  Version
    local_action: shell echo "This is  {{ ansible_distribution }} {{ ansible_distribution_major_version }}" >> /tmp/output

Use the LastLogonDate property and you won't have to convert the date/time. lastLogonTimestamp should equal to LastLogonDate when converted. This way, you will get the last logon date and time across the domain without needing to convert the result.

Your calls are made recursively which pushes functions on to the stack infinitely that causes max call stack exceeded error due to recursive behavior. Instead try using setTimeout which is a callback.

Also based on your markup your selector is wrong. it should be #advisersDiv

Demo

function fadeIn() {
    $('#pulseDiv').find('div#advisersDiv').delay(400).addClass("pulse");
    setTimeout(fadeOut,1); //<-- Provide any delay here
};

function fadeOut() {
    $('#pulseDiv').find('div#advisersDiv').delay(400).removeClass("pulse");
    setTimeout(fadeIn,1);//<-- Provide any delay here
};
fadeIn();

In the MongoDB Client, type:

db.Collection.updateMany({}, $set: {field1: 'field1', field2: 'field2'})

New in version 3.2

Params::

{}:  select all records updated

Keyword argument multi not taken

mydict = dict(zip(df.id, df.value))

There are several ways to handle this problem. If this object is related to some external library, the best solution would be to find the actual definitions file (great repository here) for that library and reference it, e.g.:

/// <reference path="/path/to/jquery.d.ts" >

Of course, this doesn't apply in many cases.

If you want to 'override' the type system, try the following:

declare var y;

This will let you make any calls you want on var y.

If you need this in derived classes, you can put that code in the base class:

protected string GetThisClassName() { return this.GetType().Name; }

Then, you can reach the name in the derived class. Returns derived class name. Of course, when using the new keyword "nameof", there will be no need like this variety acts.

Besides you can define this:

public static class Extension
{
    public static string NameOf(this object o)
    {
        return o.GetType().Name;
    }
}

And then use like this:

public class MyProgram
{
    string thisClassName;

    public MyProgram()
    {
        this.thisClassName = this.NameOf();
    }
}

You should use the csv module to read the tab-separated value file. Do not read it into memory in one go. Each row you read has all the information you need to write rows to the output CSV file, after all. Keep the output file open throughout.

import csv

with open('sample.txt', newline='') as tsvin, open('new.csv', 'w', newline='') as csvout:
    tsvin = csv.reader(tsvin, delimiter='\t')
    csvout = csv.writer(csvout)

    for row in tsvin:
        count = int(row[4])
        if count > 0:
            csvout.writerows([row[2:4] for _ in range(count)])

or, using the itertools module to do the repeating with itertools.repeat():

from itertools import repeat
import csv

with open('sample.txt', newline='') as tsvin, open('new.csv', 'w', newline='') as csvout:
    tsvin = csv.reader(tsvin, delimiter='\t')
    csvout = csv.writer(csvout)

    for row in tsvin:
        count = int(row[4])
        if count > 0:
            csvout.writerows(repeat(row[2:4], count))

1. Enter the multiplier in a cell
2. Copy that cell to the clipboard
3. Select the range you want to multiply by the multiplier

4. (Excel 2003 or earlier) Choose Edit | Paste Special | Multiply

   (Excel 2007 or later) Click on the Paste down arrow | Paste Special | Multiply

This is how I usually do it. A simple number of days perspective of B minus A.

DATE_PART('day', MAX(joindate) - MIN(joindate)) as date_diff

Remember that after installing Imagick (or indeed any PHP module) you need to restart your web server and/or php-fpm if you're using it, for the module to appear in phpinfo().

you could just do this (SQL 2008):

declare @SomeDate date = getdate()

select @SomeDate

2009-05-28

Because you store the array in the stack. You should store it in the heap. See this link to understand the concept of the heap and the stack.

Roughly you can do it like that :

try
{
    //do something
}
catch (Exception ex)
{
    string script = "<script>alert('" + ex.Message + "');</script>";
    if (!Page.IsStartupScriptRegistered("myErrorScript"))
    {
         Page.ClientScript.RegisterStartupScript("myErrorScript", script);
    }
}

But I recommend you to define your custom Exception and throw it anywhere you need. At your page catch this custom exception and register your message box script.

In C++

using namespace std;

string my_string {"Hello world"};
string element_to_be_found {"Hello"};

if(my_string.find(element_to_be_found)!=string::npos)
   std::cout<<"Element Found"<<std::endl;

In your tsconfig.json file set the parameter "noImplicitAny": false under compilerOptions to get rid of this error.

Take a look at this.

Change your query to:

SET @rank=0;
SELECT @rank:=@rank+1 AS rank, itemID, COUNT(*) as ordercount
  FROM orders
  GROUP BY itemID
  ORDER BY ordercount DESC;
SELECT @rank;

The last select is your count.

The following transact SQL script works for all languages (international). The solution is not to check for alphanumeric but to check for not containing special characters.

DECLARE @teststring nvarchar(max)
SET @teststring = 'Test''Me'
SELECT 'IS ALPHANUMERIC: ' + @teststring
WHERE @teststring NOT LIKE '%[-!#%&+,./:;<=>@`{|}~"()*\\\_\^\?\[\]\'']%' {ESCAPE '\'}

Using jdom2 : http://www.jdom.org/

import java.io.StringReader;
import org.jdom2.input.SAXBuilder;
import org.jdom2.output.Format;
import org.jdom2.output.XMLOutputter;

String prettyXml = new XMLOutputter(Format.getPrettyFormat()).
                         outputString(new SAXBuilder().build(new StringReader(uglyXml)));

If you want your script to return values, just do return [1,2,3] from a function wrapping your code but then you'd have to import your script from another script to even have any use for that information:

Return values (from a wrapping-function)

(again, this would have to be run by a separate Python script and be imported in order to even do any good):

import ...
def main():
    # calculate stuff
    return [1,2,3]

Exit codes as indicators

(This is generally just good for when you want to indicate to a governor what went wrong or simply the number of bugs/rows counted or w/e. Normally 0 is a good exit and >=1 is a bad exit but you could inter-prate them in any way you want to get data out of it)

import sys
# calculate and stuff
sys.exit(100)

And exit with a specific exit code depending on what you want that to tell your governor. I used exit codes when running script by a scheduling and monitoring environment to indicate what has happened.

(os._exit(100) also works, and is a bit more forceful)

Stdout as your relay

If not you'd have to use stdout to communicate with the outside world (like you've described). But that's generally a bad idea unless it's a parser executing your script and can catch whatever it is you're reporting to.

import sys
# calculate stuff
sys.stdout.write('Bugs: 5|Other: 10\n')
sys.stdout.flush()
sys.exit(0)

Are you running your script in a controlled scheduling environment then exit codes are the best way to go.

Files as conveyors

There's also the option to simply write information to a file, and store the result there.

# calculate
with open('finish.txt', 'wb') as fh:
    fh.write(str(5)+'\n')

And pick up the value/result from there. You could even do it in a CSV format for others to read simplistically.

Sockets as conveyors

If none of the above work, you can also use network sockets locally *(unix sockets is a great way on nix systems). These are a bit more intricate and deserve their own post/answer. But editing to add it here as it's a good option to communicate between processes. Especially if they should run multiple tasks and return values.

Per the specification, the JSON grammar's char production can take the following values:

• any-Unicode-character-except-"-or-\-or-control-character
• \"
• \\
• \/
• \b
• \f
• \n
• \r
• \t
• \u four-hex-digits

Newlines are "control characters", so no, you may not have a literal newline within your string. However, you may encode it using whatever combination of \n and \r you require.

The JSONLint tool confirms that your JSON is invalid.

And, if you want to write newlines inside your JSON syntax without actually including newlines in the data, then you're doubly out of luck. While JSON is intended to be human-friendly to a degree, it is still data and you're trying to apply arbitrary formatting to that data. That is absolutely not what JSON is about.

Just restart the apache2 and mysql:

• apache2: sudo /etc/init.d/apache2 restart

• mysql: sudo /etc/init.d/mysql restart

then refresh your browser, enjoy phpmyadmin :)

Can You Please try this : Check the web site properties in IIS. Under home directory tab, check the application pool value Verify that all SharePoint services are started. If the application is not started do the following: I think this error might occur because of changing the service account password. You may need to change the new password to application pool
1)Click the stopped application pool 2)click advanced settings 3)Identity ->click the user to retype the user 4) Application Pool Identity dialog 5)click set -> manually type the user name and password. Then restart the server.

You cannot change the Width and Height properties of the Form as they are readonly. You can change the form's size like this:

button1_Click(object sender, EventArgs e)
{
    // This will change the Form's Width and Height, respectively.
    this.Size = new Size(420, 200);
}

Use \n where you want to insert a new line Hopefully it will help you

No, you cannot specify whether the stroke is drawn inside or outside an element. I made a proposal to the SVG working group for this functionality in 2003, but it received no support (or discussion).

As I noted in the proposal,

• you can achieve the same visual result as "inside" by doubling your stroke width and then using a clipping path to clip the object to itself, and
• you can achieve the same visual result as 'outside' by doubling the stroke width and then overlaying a no-stroke copy of the object on top of itself.

Edit: This answer may be wrong in the future. It should be possible to achieve these results using SVG Vector Effects, by combining veStrokePath with veIntersect (for 'inside') or with veExclude (for 'outside). However, Vector Effects are still a working draft module with no implementations that I can yet find.

Edit 2: The SVG 2 draft specification includes a stroke-alignment property (with center|inside|outside possible values). This property may make it into UAs eventually.

Edit 3: Amusingly and dissapointingly, the SVG working group has removed stroke-alignment from SVG 2. You can see some of the concerns described after the prose here.

The answers here are very good, but still insufficient for me.

I wrote a small loop that compares Uri.EscapeUriString with Uri.EscapeDataString for all characters from 0 to 255.

NOTE: Both functions have the built-in intelligence that characters above 0x80 are first UTF-8 encoded and then percent encoded.

Here is the result:

******* Different *******

'#' -> Uri "#" Data "%23"
'$' -> Uri "$" Data "%24"
'&' -> Uri "&" Data "%26"
'+' -> Uri "+" Data "%2B"
',' -> Uri "," Data "%2C"
'/' -> Uri "/" Data "%2F"
':' -> Uri ":" Data "%3A"
';' -> Uri ";" Data "%3B"
'=' -> Uri "=" Data "%3D"
'?' -> Uri "?" Data "%3F"
'@' -> Uri "@" Data "%40"


******* Not escaped *******

'!' -> Uri "!" Data "!"
''' -> Uri "'" Data "'"
'(' -> Uri "(" Data "("
')' -> Uri ")" Data ")"
'*' -> Uri "*" Data "*"
'-' -> Uri "-" Data "-"
'.' -> Uri "." Data "."
'_' -> Uri "_" Data "_"
'~' -> Uri "~" Data "~"

'0' -> Uri "0" Data "0"
.....
'9' -> Uri "9" Data "9"

'A' -> Uri "A" Data "A"
......
'Z' -> Uri "Z" Data "Z"

'a' -> Uri "a" Data "a"
.....
'z' -> Uri "z" Data "z"

******* UTF 8 *******

.....
'Ò' -> Uri "%C3%92" Data "%C3%92"
'Ó' -> Uri "%C3%93" Data "%C3%93"
'Ô' -> Uri "%C3%94" Data "%C3%94"
'Õ' -> Uri "%C3%95" Data "%C3%95"
'Ö' -> Uri "%C3%96" Data "%C3%96"
.....

EscapeUriString is to be used to encode URLs, while EscapeDataString is to be used to encode for example the content of a Cookie, because Cookie data must not contain the reserved characters '=' and ';'.

This is old question but my case shows that my case wasn't discussed here.

I like the most the answer of Simon_Weaver (https://stackoverflow.com/a/54411397/2903893). He explains in details how to get user name using IPrincipal and IIdentity. This answer is absolutely correct and I recommend to use this approach. However, during debugging I encountered with the problem when ASP.NET can NOT populate service principle properly. (or in other words, IPrincipal.Identity.Name is null)

It's obvious that to get user name MVC framework should take it from somewhere. In the .NET world, ASP.NET or ASP.NET Core is using Open ID Connect middleware. In the simple scenario web apps authenticate a user in a web browser. In this scenario, the web application directs the user’s browser to sign them in to Azure AD. Azure AD returns a sign-in response through the user’s browser, which contains claims about the user in a security token. To make it work in the code for your application, you'll need to provide the authority to which you web app delegates sign-in. When you deploy your web app to Azure Service the common scenario to meet this requirements is to configure web app: "App Services" -> YourApp -> "Authentication / Authorization" blade -> "App Service Authenticatio" = "On" and so on (https://github.com/Huachao/azure-content/blob/master/articles/app-service-api/app-service-api-authentication.md). I beliebe (this is my educated guess) that under the hood of this process the wizard adjusts "parent" web config of this web app by adding the same settings that I show in following paragraphs. Basically, the issue why this approach does NOT work in ASP.NET Core is because "parent" machine config is ignored by webconfig. (this is not 100% sure, I just give the best explanation that I have). So, to meke it work you need to setup this manually in your app.

Here is an article that explains how to manyally setup your app to use Azure AD. https://github.com/Azure-Samples/active-directory-aspnetcore-webapp-openidconnect-v2/tree/aspnetcore2-2

Step 1: Register the sample with your Azure AD tenant. (it's obvious, don't want to spend my time of explanations).

Step 2: In the appsettings.json file: replace the ClientID value with the Application ID from the application you registered in Application Registration portal on Step 1. replace the TenantId value with common

Step 3: Open the Startup.cs file and in the ConfigureServices method, after the line containing .AddAzureAD insert the following code, which enables your application to sign in users with the Azure AD v2.0 endpoint, that is both Work and School and Microsoft Personal accounts.

services.Configure<OpenIdConnectOptions>(AzureADDefaults.OpenIdScheme, options =>
{
    options.Authority = options.Authority + "/v2.0/";
    options.TokenValidationParameters.ValidateIssuer = false;
});

Summary: I've showed one more possible issue that could leed to an error that topic starter is explained. The reason of this issue is missing configurations for Azure AD (Open ID middleware). In order to solve this issue I propose manually setup "Authentication / Authorization". The short overview of how to setup this is added.

Beginning from version 1.2.0-alpha02 of androidx recyclerView library, it is now automatically managed. Just add it with:

implementation "androidx.recyclerview:recyclerview:1.2.0-alpha02"

And use:

adapter.stateRestorationPolicy = StateRestorationPolicy.PREVENT_WHEN_EMPTY

The StateRestorationPolicy enum has 3 options:

• ALLOW — the default state, that restores the RecyclerView state immediately, in the next layout pass
• PREVENT_WHEN_EMPTY — restores the RecyclerView state only when the adapter is not empty (adapter.getItemCount() > 0). If your data is loaded async, the RecyclerView waits until data is loaded and only then the state is restored. If you have default items, like headers or load progress indicators as part of your Adapter, then you should use the PREVENT option, unless the default items are added using MergeAdapter. MergeAdapter waits for all of its adapters to be ready and only then it restores the state.
• PREVENT — all state restoration is deferred until you set ALLOW or PREVENT_WHEN_EMPTY.

Note that at the time of this answer, recyclerView library is still in alpha03, but alpha phase is not suitable for production purposes.
