So In my case, After trying all the above options, I realized it was VPN (company firewall).once connected and ran cmd: clean install spring-boot:run. Issue is resolved. Step 1: check maven is configured correctly or not. Step 2: check settings.xml is mapped correctly or not. Step 3: verify if you are behind any firewall then map your repo urls accordingly. Step 4:run clean install spring-boot:run step 5: issue is resolved.

I faced the same issue but, in my case, I had only to point my project to a JDK instead of the JRE in the build path then it solved the issue and I was able to import all maven dependencies with no problem!

first, check that who uses port 8080.

• telnet localhost 8080
• use browser to open http://localhost:8080

if the port 8080 is in use, change the listening port to 8181.

if you use IDEA, modify start configuration, Run-> Edit Configuration enter image description here

if you use mvn spring-boot, then use the command:

mvn spring-boot:run -Dserver.port=8181

if you use java -jar, then use the command:

java -jar xxxx.jar --server.port=8181

It is possibly to use the flag -o,--offline "Work offline" to prevent that.

Like this:

maven compile -o

I had the same issue. Fixed by adding a pom.xml in parent folder with <modules> listed.

You're probably missing some dependencies.

Locate the dependencies you're missing with mvn dependency:tree, then install them manually, and build your project with the -o (offline) option.

I faced the same issue. Setting relative path of the parent in module projects solved the issue.

Use <relativePath>../Parent Project Name/pom.xml</relativePath>

If you're using a shell, the filepath to the Download (no "s") folder is

/storage/emulated/0/Download

For those who like Debian and prepackaged Java:

sudo mkdir /usr/share/ca-certificates/test/  # don't mess with other certs
sudo cp ~/tmp/test.loc.crt /usr/share/ca-certificates/test/
sudo dpkg-reconfigure --force ca-certificates  # check your cert in curses GUI!
sudo update-ca-certificates --fresh --verbose

Don't forget to check /etc/default/cacerts for:

# enable/disable updates of the keystore /etc/ssl/certs/java/cacerts
cacerts_updates=yes

To remove cert:

sudo rm /usr/share/ca-certificates/test/test.loc.crt
sudo rm /etc/ssl/certs/java/cacerts
sudo update-ca-certificates --fresh --verbose

Try set-executionpolicy "Policyname" -force switch and the warnings pop-up should not come.

Maybe the problem only in your IDE encoding settings. Try to set UTF-8 everywhere:

To get the current time in the local timezone as a naive datetime object:

from datetime import datetime
naive_dt = datetime.now()

If it doesn't return the expected time then it means that your computer is misconfigured. You should fix it first (it is unrelated to Python).

To get the current time in UTC as a naive datetime object:

naive_utc_dt = datetime.utcnow()

To get the current time as an aware datetime object in Python 3.3+:

from datetime import datetime, timezone

utc_dt = datetime.now(timezone.utc) # UTC time
dt = utc_dt.astimezone() # local time

To get the current time in the given time zone from the tz database:

import pytz

tz = pytz.timezone('Europe/Berlin')
berlin_now = datetime.now(tz)

It works during DST transitions. It works if the timezone had different UTC offset in the past i.e., it works even if the timezone corresponds to multiple tzinfo objects at different times.

public static void main(String[] args) {
    String s="sdf sdfsdfsd sdfsdfsd sdfsdfsd sdf sdf sdf ";
    String st[]=s.split(" ");
    System.out.println(st.length);
    Map<String, Integer> mp= new TreeMap<String, Integer>();
    for(int i=0;i<st.length;i++){

        Integer count=mp.get(st[i]);
        if(count == null){
            count=0;
        }           
        mp.put(st[i],++count);
    }
   System.out.println(mp.size());
   System.out.println(mp.get("sdfsdfsd"));


}

  <script type="text/javascript">
  jQuery(document).ready(function(){
         setTimeout(PopUp(),5000); // invoke Popup function after 5 seconds 
  });
   </script>

This function will round either be order of magnitude (right to left) or by digits the same way that format treats floating point decimal places (left to right:

def intround(n, p):
    ''' rounds an intger. if "p"<0, p is a exponent of 10; if p>0, left to right digits '''
    if p==0: return n
    if p>0:  
        ln=len(str(n))  
        p=p-ln+1 if n<0 else p-ln
    return (n + 5 * 10**(-p-1)) // 10**-p * 10**-p

>>> tgt=5555555
>>> d=2
>>> print('\t{} rounded to {} places:\n\t{} right to left \n\t{} left to right'.format(
        tgt,d,intround(tgt,-d), intround(tgt,d))) 

Prints

5555555 rounded to 2 places:
5555600 right to left 
5600000 left to right

You can also use Decimal class:

import decimal
import sys

def ri(i, prec=6):
    ic=long if sys.version_info.major<3 else int
    with decimal.localcontext() as lct:
        if prec>0:
            lct.prec=prec
        else:
            lct.prec=len(str(decimal.Decimal(i)))+prec  
        n=ic(decimal.Decimal(i)+decimal.Decimal('0'))
    return n

On Python 3 you can reliably use round with negative places and get a rounded integer:

def intround2(n, p):
    ''' will fail with larger floating point numbers on Py2 and require a cast to an int '''
    if p>0:
        return round(n, p-len(str(n))+1)
    else:
        return round(n, p)    

On Python 2, round will fail to return a proper rounder integer on larger numbers because round always returns a float:

>>> round(2**34, -5)
17179900000.0                     # OK
>>> round(2**64, -5)
1.84467440737096e+19              # wrong 

The other 2 functions work on Python 2 and 3

If you mean if you can do ctor chaining in C#, the answer is yes. The question has already been asked.

However it seems from the comments, it seems what you really intend to ask is 'Can I call an overloaded constructor from within another constructor with pre/post processing?'
Although C# doesn't have the syntax to do this, you could do this with a common initialization function (like you would do in C++ which doesn't support ctor chaining)

class A
{
  //ctor chaining
  public A() : this(0)
  {  
      Console.WriteLine("default ctor"); 
  }

  public A(int i)
  {  
      Init(i); 
  }

  // what you want
  public A(string s)
  {  
      Console.WriteLine("string ctor overload" );
      Console.WriteLine("pre-processing" );
      Init(Int32.Parse(s));
      Console.WriteLine("post-processing" );
  }

   private void Init(int i)
   {
      Console.WriteLine("int ctor {0}", i);
   }
}

First, eq is for comparing strings; == is for comparing numbers.

Even if the "if" condition is satisfied, it doesn't evaluate the "then" block.

I think your problem is that your variables don't contain what you think they do. I think your $str1 or $str2 contains something like "taste\n" or so. Check them by printing before your if: print "str1='$str1'\n";.

The trailing newline can be removed with the chomp($str1); function.

It's simple as:

$('#action').val("1");

#action is hidden input field id.

This answer might seem silly but I had my laptop's power plan set to something other than High performance (in Windows). I would constantly get out of memory warnings in Visual Studio and things would run a bit slow. After I changed the power setting to High performance, I no longer see any problem.

Sometimes I need to import large xlsx files into database, so I use spreadsheet-reader as it can read file per-row. It is very memory-efficient way to import.

<?php
    // If you need to parse XLS files, include php-excel-reader
    require('php-excel-reader/excel_reader2.php');

    require('SpreadsheetReader.php');

    $Reader = new SpreadsheetReader('example.xlsx');
    // insert every row just after reading it
    foreach ($Reader as $row)
    {
        $db->insert($row);
    }
?>

Your question is based on assumption that the code which may throw NullPointerException is worse than the code which may not. This assumption is wrong. If you expect that your foobar is never null due to the program logic, it's much better to use Optional.of(foobar) as you will see a NullPointerException which will indicate that your program has a bug. If you use Optional.ofNullable(foobar) and the foobar happens to be null due to the bug, then your program will silently continue working incorrectly, which may be a bigger disaster. This way an error may occur much later and it would be much harder to understand at which point it went wrong.

in the database the date looks like this 2011-10-2

Store it in YYYY-MM-DD and then string comparison will work because '1' > '0', etc.

<asp:Button ID="btnGet" runat="server" Text="Get" OnClick="btnGet_Click" OnClientClick="retun callMethod();" />
<script type="text/javascript">
    function callMethod() {
        //your logic should be here and make sure your logic code note returing function
        return false;
}
</script>

It worked perfectly for me in this way:

    RadioGroup radioGroup = (RadioGroup) findViewById(R.id.radio_group);
    int radioButtonID = radioGroup.getCheckedRadioButtonId();
    RadioButton radioButton = (RadioButton) radioGroup.findViewById(radioButtonID);
    String selectedtext = (String) radioButton.getText();

public class Arr {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        int a[] = {1,2,3};
        //let a[] is your original array
        System.out.println(a[0] + " " + a[1] + " " + a[2]);
        int b[];
        //let b[] is your temporary array with size greater than a[]
        //I have took 5
        b = new int[5];
        //now assign all a[] values to b[]
        for(int i = 0 ; i < a.length ; i ++)
            b[i] = a[i];
        //add next index values to b
        b[3] = 4;
        b[4] = 5;
        //now assign b[] to a[]
        a = b;
        //now you can heck that size of an original array increased
        System.out.println(a[0] + " " + a[1] + " " + a[2] + " " + a[3] + " " 
    + a[4]);
    }

}

Output for the above code is:

1 2 3

1 2 3 4 5

JPanel jPanel = new JPanel();

jPanel.setBorder(BorderFactory.createLineBorder(Color.black));

Here not only jPanel, you can add border to any Jcomponent

If you need to save multiple objects, you can simply put them in a single list, or tuple, for instance:

import pickle

# obj0, obj1, obj2 are created here...

# Saving the objects:
with open('objs.pkl', 'w') as f:  # Python 3: open(..., 'wb')
    pickle.dump([obj0, obj1, obj2], f)

# Getting back the objects:
with open('objs.pkl') as f:  # Python 3: open(..., 'rb')
    obj0, obj1, obj2 = pickle.load(f)

If you have a lot of data, you can reduce the file size by passing protocol=-1 to dump(); pickle will then use the best available protocol instead of the default historical (and more backward-compatible) protocol. In this case, the file must be opened in binary mode (wb and rb, respectively).

The binary mode should also be used with Python 3, as its default protocol produces binary (i.e. non-text) data (writing mode 'wb' and reading mode 'rb').

You can use:

QString qs;
// do things
std::cout << qs.toStdString() << std::endl;

It internally uses QString::toUtf8() function to create std::string, so it's Unicode safe as well. Here's reference documentation for QString.

Solution to flatten properties and arrays as well.

Example input:

{
  obj1: {
    prop1: "value1",
    prop2: "value2"
  },
  arr1: [
    "value1",
    "value2"
  ]
}

Output:

"arr1[0]": "value1"
"arr1[1]": "value2"
"obj1.prop1": "value1"
"obj1.prop2": "value2"

Source code:

flatten(object, path = '', res = undefined) {
      if (!Array.isArray(res)) {
          res = [];
      }
      if (object !== null && typeof object === 'object') {
          if (Array.isArray(object)) {
              for (let i = 0; i < object.length; i++) {
                  this.flatten(object[i], path + '[' + i + ']', res)
              }
          } else {
              const keys = Object.keys(object)
              for (let i = 0; i < keys.length; i++) {
                  const key = keys[i]
                  this.flatten(object[key], path ? path + '.' + key : key, res)
              }
          }
      } else {
          if (path) {
              res[path] = object
          }
      }
      return res
  }

You will need to use different IP addresses. The server, whether Apache or IIS, grabs the traffic based on the IP and Port, which ever they are bound to listen to. Once it starts listening, then it uses the headers, such as the server name to filter and determine what site is being accessed. You can't do it will simply changing the server name in the request

For Electron modules, install electron-rebuild.

Format:
electron-rebuild -o <module_name> -v <electron version>

Example:
electron-rebuild -o myaddon -v 9.0.0-beta.6

Specify the same version that you have installed in the current directory

You might have this experience where a standard node-gyp build would report as 64, then a basic electron-rebuild would report 76, not until you add -v with exact version it bumps to actual version 80 (for 9.0.0-beta.6)

A few comments:

• The Nyquist frequency is half the sampling rate.
• You are working with regularly sampled data, so you want a digital filter, not an analog filter. This means you should not use analog=True in the call to butter, and you should use scipy.signal.freqz (not freqs) to generate the frequency response.
• One goal of those short utility functions is to allow you to leave all your frequencies expressed in Hz. You shouldn't have to convert to rad/sec. As long as you express your frequencies with consistent units, the scaling in the utility functions takes care of the normalization for you.

Here's my modified version of your script, followed by the plot that it generates.

import numpy as np
from scipy.signal import butter, lfilter, freqz
import matplotlib.pyplot as plt


def butter_lowpass(cutoff, fs, order=5):
    nyq = 0.5 * fs
    normal_cutoff = cutoff / nyq
    b, a = butter(order, normal_cutoff, btype='low', analog=False)
    return b, a

def butter_lowpass_filter(data, cutoff, fs, order=5):
    b, a = butter_lowpass(cutoff, fs, order=order)
    y = lfilter(b, a, data)
    return y


# Filter requirements.
order = 6
fs = 30.0       # sample rate, Hz
cutoff = 3.667  # desired cutoff frequency of the filter, Hz

# Get the filter coefficients so we can check its frequency response.
b, a = butter_lowpass(cutoff, fs, order)

# Plot the frequency response.
w, h = freqz(b, a, worN=8000)
plt.subplot(2, 1, 1)
plt.plot(0.5*fs*w/np.pi, np.abs(h), 'b')
plt.plot(cutoff, 0.5*np.sqrt(2), 'ko')
plt.axvline(cutoff, color='k')
plt.xlim(0, 0.5*fs)
plt.title("Lowpass Filter Frequency Response")
plt.xlabel('Frequency [Hz]')
plt.grid()


# Demonstrate the use of the filter.
# First make some data to be filtered.
T = 5.0         # seconds
n = int(T * fs) # total number of samples
t = np.linspace(0, T, n, endpoint=False)
# "Noisy" data.  We want to recover the 1.2 Hz signal from this.
data = np.sin(1.2*2*np.pi*t) + 1.5*np.cos(9*2*np.pi*t) + 0.5*np.sin(12.0*2*np.pi*t)

# Filter the data, and plot both the original and filtered signals.
y = butter_lowpass_filter(data, cutoff, fs, order)

plt.subplot(2, 1, 2)
plt.plot(t, data, 'b-', label='data')
plt.plot(t, y, 'g-', linewidth=2, label='filtered data')
plt.xlabel('Time [sec]')
plt.grid()
plt.legend()

plt.subplots_adjust(hspace=0.35)
plt.show()

If you commit one file and push your revision, it will not transfer the whole repository, it will push changes.

This is called string interpolation; it doesn't exist as such in Java.

One approach is to use String.format:

String string = String.format("A string %s", aVariable);

Another approach is to use a templating library such as Velocity or FreeMarker.

products = [{"name":"Pizza","price":"10","quantity":"7"}, {"name":"Cerveja","price":"12","quantity":"5"}, {"name":"Hamburguer","price":"10","quantity":"2"}, {"name":"Fraldas","price":"6","quantity":"2"}];

change to

products = '[{"name":"Pizza","price":"10","quantity":"7"}, {"name":"Cerveja","price":"12","quantity":"5"}, {"name":"Hamburguer","price":"10","quantity":"2"}, {"name":"Fraldas","price":"6","quantity":"2"}]';

Please check your listenning ports with :

netstat -nat |grep :3306

If it show

 tcp        0      0 0.0.0.0:3306            0.0.0.0:*               LISTEN 

Thats is ok for your remote connection.

But in this case i think you have

tcp        0     192.168.1.3:3306            0.0.0.0:*               LISTEN 

Thats is ok for your remote connection. You should also check your firewall (iptables if you centos/redhat)

services iptables stop

for testing or use :

iptables -A input -p tcp -i eth0 --dport 3306 -m state NEW,ESTABLISHED -j ACCEPT
iptables -A output -p tcp -i eth0 --sport 3306 -m state NEW,ESTABLISHED -j ACCEPT

And another thing to check your grant permission for remote connection :

GRANT ALL ON *.* TO remoteUser@'remoteIpadress' IDENTIFIED BY 'my_password';

The problem is that IE won't reset the proxy settings until it either

1. closes, or
2. has its configuration refreshed.

Below is the code that I've used to get this working:

function Refresh-System
{
  $signature = @'
[DllImport("wininet.dll", SetLastError = true, CharSet=CharSet.Auto)]
public static extern bool InternetSetOption(IntPtr hInternet, int dwOption, IntPtr lpBuffer, int dwBufferLength);
'@

$INTERNET_OPTION_SETTINGS_CHANGED   = 39
$INTERNET_OPTION_REFRESH            = 37
$type = Add-Type -MemberDefinition $signature -Name wininet -Namespace pinvoke -PassThru
$a = $type::InternetSetOption(0, $INTERNET_OPTION_SETTINGS_CHANGED, 0, 0)
$b = $type::InternetSetOption(0, $INTERNET_OPTION_REFRESH, 0, 0)
return $a -and $b
}

In case you are using WPF and Xceed's TimePicker (which seems to be using DateTime?) as a timespan picker -as I do right now- you can get the total milliseconds (or a TimeSpan) out of it like so:

var milliseconds = DateTimeToTimeSpan(timePicker.Value).TotalMilliseconds;

    TimeSpan DateTimeToTimeSpan(DateTime? ts)
    {
        if (!ts.HasValue) return TimeSpan.Zero;
        else return new TimeSpan(0, ts.Value.Hour, ts.Value.Minute, ts.Value.Second, ts.Value.Millisecond);
    }

XAML :

<Xceed:TimePicker x:Name="timePicker" Format="Custom" FormatString="H'h 'm'm 's's'" />

If not, I guess you could just adjust my DateTimeToTimeSpan() so that it also takes 'days' into account or do sth like dateTime.Substract(DateTime.MinValue).TotalMilliseconds.

Try out using getDate feature of datepicker.

$.datepicker.formatDate('yy-mm-dd',new Date(pField.datepicker("getDate")));

Also worth noting is that as well as __version__ being a semi-std. in python so is __version_info__ which is a tuple, in the simple cases you can just do something like:

__version__ = '1.2.3'
__version_info__ = tuple([ int(num) for num in __version__.split('.')])

...and you can get the __version__ string from a file, or whatever.

if you forget ,,this will happen,it's weird

a variable declared with or without the var keyword got attached to the global object. This is the basis for creating global variables in Node by declaring variables without the var keyword. While variables declared with the var keyword remain local to a module.

This type of situation is implementation dependent and consequently it will require a vendor specific mechanism in order to trap. With Microsoft this will involve SEH, and *nix will involve a signal

In general though catching an Access Violation exception is a very bad idea. There is almost no way to recover from an AV exception and attempting to do so will just lead to harder to find bugs in your program.

Use the mapfile command:

mapfile -t myArray < file.txt

The error is using for -- the idiomatic way to loop over lines of a file is:

while IFS= read -r line; do echo ">>$line<<"; done < file.txt

Well, if you have a ResultSet of type ResultSet.TYPE_FORWARD_ONLY you want to keep it that way (and not to switch to a ResultSet.TYPE_SCROLL_INSENSITIVE or ResultSet.TYPE_SCROLL_INSENSITIVE in order to be able to use .last()).

I suggest a very nice and efficient hack, where you add a first bogus/phony row at the top containing the number of rows.

Example

Let's say your query is the following

select MYBOOL,MYINT,MYCHAR,MYSMALLINT,MYVARCHAR
from MYTABLE
where ...blahblah...

and your output looks like

true    65537 "Hey" -32768 "The quick brown fox"
false  123456 "Sup"    300 "The lazy dog"
false -123123 "Yo"       0 "Go ahead and jump"
false       3 "EVH"    456 "Might as well jump"
...
[1000 total rows]

Simply refactor your code to something like this:

Statement s=myConnection.createStatement(ResultSet.TYPE_FORWARD_ONLY,
                                         ResultSet.CONCUR_READ_ONLY);
String from_where="FROM myTable WHERE ...blahblah... ";
//h4x
ResultSet rs=s.executeQuery("select count(*)as RECORDCOUNT,"
                           +       "cast(null as boolean)as MYBOOL,"
                           +       "cast(null as int)as MYINT,"
                           +       "cast(null as char(1))as MYCHAR,"
                           +       "cast(null as smallint)as MYSMALLINT,"
                           +       "cast(null as varchar(1))as MYVARCHAR "
                           +from_where
                           +"UNION ALL "//the "ALL" part prevents internal re-sorting to prevent duplicates (and we do not want that)
                           +"select cast(null as int)as RECORDCOUNT,"
                           +       "MYBOOL,MYINT,MYCHAR,MYSMALLINT,MYVARCHAR "
                           +from_where);

Your query output will now be something like

1000 null     null null    null null
null true    65537 "Hey" -32768 "The quick brown fox"
null false  123456 "Sup"    300 "The lazy dog"
null false -123123 "Yo"       0 "Go ahead and jump"
null false       3 "EVH"    456 "Might as well jump"
...
[1001 total rows]

So you just have to

if(rs.next())
    System.out.println("Recordcount: "+rs.getInt("RECORDCOUNT"));//hack: first record contains the record count
while(rs.next())
    //do your stuff

I'm guessing you mean ignoring case when searching in a string?

I don't know any, but you could try to convert the string to search into either to lower or to upper case, then search.

// s is the String to search into, and seq the sequence you are searching for.
bool doesContain = s.toLowerCase().contains(seq);

Edit: As Ryan Schipper suggested, you can also (and probably would be better off) do seq.toLowerCase(), depending on your situation.

In PL/SQL, there is a trick to use the undocumented OWA_UTIL.ITE function.

This thread has some considerable debate about whether BN should be applied before non-linearity of current layer or to the activations of the previous layer.

Although there is no correct answer, the authors of Batch Normalization say that It should be applied immediately before the non-linearity of the current layer. The reason ( quoted from original paper) -

"We add the BN transform immediately before the nonlinearity, by normalizing x = Wu+b. We could have also normalized the layer inputs u, but since u is likely the output of another nonlinearity, the shape of its distribution is likely to change during training, and constraining its first and second moments would not eliminate the covariate shift. In contrast, Wu + b is more likely to have a symmetric, non-sparse distribution, that is “more Gaussian” (Hyv¨arinen & Oja, 2000); normalizing it is likely to produce activations with a stable distribution."

There's also this quick (and somewhat dirty) one-liner:

$linecount=0; $i=0; Get-Content .\BIG_LOG_FILE.txt | %{ Add-Content OUT$i.log "$_"; $linecount++; if ($linecount -eq 3000) {$I++; $linecount=0 } }

You can tweak the number of first lines per batch by changing the hard-coded 3000 value.

For this you can have a Car base class that implement the year field, and all other implementations can inheritance from it.

Make a copy of your git dir in your local host and run git init there once again. Push the project to a brand new reprository.

Whilst more of a workaround, if you're running an Intel Mac, you could go the virtualisation route - at least then you can run the same tools.

If you use chldNode as XmlElement instead of XmlNode, you can use

var attributeValue = chldNode.GetAttribute("Name");

The return value will just be an empty string, in case the attribute name does not exist.

So your loop could look like this:

XmlDocument document = new XmlDocument();
var nodes = document.SelectNodes("//Node/N0de/node");

foreach (XmlElement node in nodes)
{
    var attributeValue = node.GetAttribute("Name");
}

This will select all nodes <node> surrounded by <Node><N0de></N0de><Node> tags and subsequently loop through them and read the attribute "Name".

Try this library (javadoc is here), min API level is 7:

dependencies {
    compile 'com.shamanland:fab:0.0.8'
}

It provides single widget with ability to customize it via Theme, xml or java-code.

It's very simple to use. There are available normal and mini implementation according to Promoted Actions pattern.

<com.shamanland.fab.FloatingActionButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/ic_action_my"
    app:floatingActionButtonColor="@color/my_fab_color"
    app:floatingActionButtonSize="mini"
    />

Try to compile the demo app. There is exhaustive example: light and dark themes, using with ListView, align between two Views.

Use numpy. array. flatten() to convert a 2D NumPy array into a 1D array print(array_2d) array_1d = array_2d. flatten() flatten array_2d print(array_1d)

All the technical talking is overcomplicating the concept.

If you put GC into C++ for all the memory automatically then consider something like a web browser. The web browser must load a full web document AND run web scripts. You can store web script variables in the document tree. In a BIG document in a browser with lots of tabs open, it means that every time the GC must do a full collection it must also scan all the document elements.

On most computers this means that PAGE FAULTS will occur. So the main reason, to answer the question is that PAGE FAULTS will occur. You will know this as when your PC starts making lots of disk access. This is because the GC must touch lots of memory in order to prove invalid pointers. When you have a bona fide application using lots of memory, having to scan all objects every collection is havoc because of the PAGE FAULTS. A page fault is when virtual memory needs to get read back into RAM from disk.

So the correct solution is to divide an application into the parts that need GC and the parts that do not. In the case of the web browser example above, if the document tree was allocated with malloc, but the javascript ran with GC, then every time the GC kicks in it only scans a small portion of memory and all PAGED OUT elements of the memory for the document tree does not need to get paged back in.

To further understand this problem, look up on virtual memory and how it is implemented in computers. It is all about the fact that 2GB is available to the program when there is not really that much RAM. On modern computers with 2GB RAM for a 32BIt system it is not such a problem provided only one program is running.

As an additional example, consider a full collection that must trace all objects. First you must scan all objects reachable via roots. Second scan all the objects visible in step 1. Then scan waiting destructors. Then go to all the pages again and switch off all invisible objects. This means that many pages might get swapped out and back in multiple times.

So my answer to bring it short is that the number of PAGE FAULTS which occur as a result of touching all the memory causes full GC for all objects in a program to be unfeasible and so the programmer must view GC as an aid for things like scripts and database work, but do normal things with manual memory management.

And the other very important reason of course is global variables. In order for the collector to know that a global variable pointer is in the GC it would require specific keywords, and thus existing C++ code would not work.

(In the diagrams and text below, PC is the address of the branch instruction itself. PC+4 is the end of the branch instruction itself, and the start of the branch delay slot. Except in the absolute jump diagram.)

1. Branch Address Calculation

In MIPS branch instruction has only 16 bits offset to determine next instruction. We need a register added to this 16 bit value to determine next instruction and this register is actually implied by architecture. It is PC register since PC gets updated (PC+4) during the fetch cycle so that it holds the address of the next instruction.

We also limit the branch distance to -2^15 to +2^15 - 1 instruction from the (instruction after the) branch instruction. However, this is not real issue since most branches are local anyway.

So step by step :

• Sign extend the 16 bit offset value to preserve its value.
• Multiply resulting value with 4. The reason behind this is that If we are going to branch some address, and PC is already word aligned, then the immediate value has to be word-aligned as well. However, it makes no sense to make the immediate word-aligned because we would be wasting low two bits by forcing them to be 00.
• Now we have a 32 bit relative offset. Add this value to PC + 4 and that is your branch address.

2. Jump Address Calculation

For Jump instruction MIPS has only 26 bits to determine Jump location. Jumps are relative to PC in MIPS. Like branch, immediate jump value needs to be word-aligned; therefore, we need to multiply 26 bit address with four.

Again step by step:

• Multiply 26 bit value with 4.
• Since we are jumping relative to PC+4 value, concatenate first four bits of PC+4 value to left of our jump address.
• Resulting address is the jump value.

In other words, replace the lower 28 bits of the PC + 4 with the lower 26 bits of the fetched instruction shifted left by 2 bits.

Jumps are region-relative to the branch-delay slot, not necessarily the branch itself. In the diagram above, PC has already advanced to the branch delay slot before the jump calculation. (In a classic-RISC 5 stage pipeline, the BD was fetched in the same cycle the jump is decoded, so that PC+4 next instruction address is already available for jumps as well as branches, and calculating relative to the jump's own address would have required extra work to save that address.)

One possible solution:

import java.lang.StringBuilder;

class Test {
  private static final int sizeOfIntInHalfBytes = 8;
  private static final int numberOfBitsInAHalfByte = 4;
  private static final int halfByte = 0x0F;
  private static final char[] hexDigits = { 
    '0', '1', '2', '3', '4', '5', '6', '7', 
    '8', '9', 'A', 'B', 'C', 'D', 'E', 'F'
  };

  public static String decToHex(int dec) {
    StringBuilder hexBuilder = new StringBuilder(sizeOfIntInHalfBytes);
    hexBuilder.setLength(sizeOfIntInHalfBytes);
    for (int i = sizeOfIntInHalfBytes - 1; i >= 0; --i)
    {
      int j = dec & halfByte;
      hexBuilder.setCharAt(i, hexDigits[j]);
      dec >>= numberOfBitsInAHalfByte;
    }
    return hexBuilder.toString(); 
  }

  public static void main(String[] args) {
     int dec = 305445566;
     String hex = decToHex(dec);
     System.out.println(hex);       
  }
}

Output:

1234BABE

Anyway, there is a library method for this:

String hex = Integer.toHexString(dec);

I faced a similar issue, and I solved that after doing the following:

1. check your jupyter configuration file: this is described here in details; https://testnb.readthedocs.io/en/stable/examples/Notebook/Configuring%20the%20Notebook%20and%20Server.html

-- you will simply need from the link above to learn how to make jupyter server listens to your local machin IP -- you will need to know your local machin IP (i use "ifconfig -a" on ubuntu to find that out) - please check for centos6

after you finish setting your configuration, you can run jupyter notebook at your local IP: jupyter notebook --ip=* --no-browser

please replace * with your IP address for example: jupyter notebook --ip=192.168.x.x --no-browser

you can now access your jupyter server from any device connected to the router using this ip:port (the port is usually 8888, so for my case for instance I used "192.168.x.x:8888" to access my server from other devices)

now if you want to access this server from public IP, you will have to:

1. find your public IP (simply type on google what is my IP)
2. use this IP address instead of your local IP to access the server from any device not connected to the same router kindly note: if your linux server runs on Virtual machine, you will need to set your router to allow accessing your VB from public IPs, settings depends on the router type. otherwise, you should be able to access the server using the public IP and the port set for it from any device not connected to your router, or using your local IP and the port set from any device connected to the same router!

Here is another solution using flexbox but without using flex-end for bottom alignment. The idea is to set margin-bottom on h1 to auto to push the remaining content to the bottom:

#header {_x000D_
  height: 350px;_x000D_
  display:flex;_x000D_
  flex-direction:column;_x000D_
  border:1px solid;_x000D_
}_x000D_
_x000D_
#header h1 {_x000D_
 margin-bottom:auto;_x000D_
}

<div id="header">_x000D_
  <h1>Header title</h1>_x000D_
  Header content (one or multiple lines) Header content (one or multiple lines)Header content (one or multiple lines) Header content (one or multiple lines)_x000D_
</div>

We can also do the same with margin-top:auto on the text but in this case we need to wrap it inside a div or span:

#header {_x000D_
  height: 350px;_x000D_
  display:flex;_x000D_
  flex-direction:column;_x000D_
  border:1px solid;_x000D_
}_x000D_
_x000D_
#header span {_x000D_
 margin-top:auto;_x000D_
}

<div id="header">_x000D_
  <h1>Header title</h1>_x000D_
  <span>Header content (one or multiple lines)</span>_x000D_
</div>

In Java, a String is a reference to heap-allocated storage. Returning "ans" only returns the reference so there is no need for stack-allocated storage. In fact, there is no way in Java to allocate objects in stack storage.

I would change to this, though. You don't need "ans" at all.

return String.format("%d:%d", mins, secs);

It's in the python docs.

import datetime
datetime.datetime.combine(datetime.date(2011, 1, 1), 
                          datetime.time(10, 23))

returns

datetime.datetime(2011, 1, 1, 10, 23)

If you use Java >= 7, you could improve the accepted solution using try with resources:

private byte[] convertToBytes(Object object) throws IOException {
    try (ByteArrayOutputStream bos = new ByteArrayOutputStream();
         ObjectOutputStream out = new ObjectOutputStream(bos)) {
        out.writeObject(object);
        return bos.toByteArray();
    } 
}

And the other way around:

private Object convertFromBytes(byte[] bytes) throws IOException, ClassNotFoundException {
    try (ByteArrayInputStream bis = new ByteArrayInputStream(bytes);
         ObjectInputStream in = new ObjectInputStream(bis)) {
        return in.readObject();
    } 
}

I've been searching for a simple way to make the sticky footer works. I just applied a class="navbar-fixed-bottom" and it worked instantly Only thing to keep in mind it's to adjust the settings of the footer for mobile devices. Cheers!

Guard statement going to do . it is couple of different

1) it is allow me to reduce nested if statement
2) it is increase my scope which my variable accessible

if Statement

func doTatal(num1 : Int?, num2: Int?) {
  // nested if statement
    if let fistNum = num1 where num1 > 0 {
        if let lastNum = num2 where num2 < 50 {

          let total = fistNum + lastNum
        }
    }
 // don't allow me to access out of the scope 
 //total = fistNum + lastNum 
}

Guard statement

func doTatal(num1 : Int?, num2: Int?) {
   //reduce  nested if statement and check positive way not negative way 
    guard let fistNum = num1 where num1 > 0 else{
      return
    }
    guard  let lastNum = num2 where num2 < 50 else {
     return
    }
    // increase my scope which my variable accessible
    let total = fistNum + lastNum

}

Git has a configuration setting that tells it whether to be case sensitive or insensitive: core.ignorecase. To tell Git to be case-senstive, simply set this setting to false. (Be careful if you have already pushed the files, then you should first move them given the other answers).

git config core.ignorecase false

Documentation

From the git config documentation:

core.ignorecase

If true, this option enables various workarounds to enable git to work better on filesystems that are not case sensitive, like FAT. For example, if a directory listing finds makefile when git expects Makefile, git will assume it is really the same file, and continue to remember it as Makefile.

The default is false, except git-clone(1) or git-init(1) will probe and set core.ignorecase true if appropriate when the repository is created.

Case-insensitive file-systems

The two most popular operating systems that have case-insensitive file systems that I know of are

• Windows
• OS X

This link explains where you're going wrong:

[35.12] Why can't I separate the definition of my templates class from its declaration and put it inside a .cpp file?

Place the definition of your constructors, destructors methods and whatnot in your header file, and that will correct the problem.

This offers another solution:

How can I avoid linker errors with my template functions?

However this requires you to anticipate how your template will be used and, as a general solution, is counter-intuitive. It does solve the corner case though where you develop a template to be used by some internal mechanism, and you want to police the manner in which it is used.

I've been trying to do something very similar but not using the nodes. However, my xml structure is a little different.

You have it like this:

<Metrics>
    <Metric id="TransactionCleanupThread.RefundOldTrans" type="timer" ...>

If it were like this instead:

<Metrics>
    <Metric>
        <id>TransactionCleanupThread.RefundOldTrans</id>
        <type>timer</type>
        .
        .
        .

Then you could simply use this SQL statement.

SELECT
    Sqm.SqmId,
    Data.value('(/Sqm/Metrics/Metric/id)[1]', 'varchar(max)') as id,
    Data.value('(/Sqm/Metrics/Metric/type)[1]', 'varchar(max)') AS type,
    Data.value('(/Sqm/Metrics/Metric/unit)[1]', 'varchar(max)') AS unit,
    Data.value('(/Sqm/Metrics/Metric/sum)[1]', 'varchar(max)') AS sum,
    Data.value('(/Sqm/Metrics/Metric/count)[1]', 'varchar(max)') AS count,
    Data.value('(/Sqm/Metrics/Metric/minValue)[1]', 'varchar(max)') AS minValue,
    Data.value('(/Sqm/Metrics/Metric/maxValue)[1]', 'varchar(max)') AS maxValue,
    Data.value('(/Sqm/Metrics/Metric/stdDeviation)[1]', 'varchar(max)') AS stdDeviation,
FROM Sqm

To me this is much less confusing than using the outer apply or cross apply.

I hope this helps someone else looking for a simpler solution!

As of what have been done, I don't see any pretty printer that at least mimics the output of the python interpreter with very simple formatting so here's mine :

class Formatter(object):
    def __init__(self):
        self.types = {}
        self.htchar = '\t'
        self.lfchar = '\n'
        self.indent = 0
        self.set_formater(object, self.__class__.format_object)
        self.set_formater(dict, self.__class__.format_dict)
        self.set_formater(list, self.__class__.format_list)
        self.set_formater(tuple, self.__class__.format_tuple)

    def set_formater(self, obj, callback):
        self.types[obj] = callback

    def __call__(self, value, **args):
        for key in args:
            setattr(self, key, args[key])
        formater = self.types[type(value) if type(value) in self.types else object]
        return formater(self, value, self.indent)

    def format_object(self, value, indent):
        return repr(value)

    def format_dict(self, value, indent):
        items = [
            self.lfchar + self.htchar * (indent + 1) + repr(key) + ': ' +
            (self.types[type(value[key]) if type(value[key]) in self.types else object])(self, value[key], indent + 1)
            for key in value
        ]
        return '{%s}' % (','.join(items) + self.lfchar + self.htchar * indent)

    def format_list(self, value, indent):
        items = [
            self.lfchar + self.htchar * (indent + 1) + (self.types[type(item) if type(item) in self.types else object])(self, item, indent + 1)
            for item in value
        ]
        return '[%s]' % (','.join(items) + self.lfchar + self.htchar * indent)

    def format_tuple(self, value, indent):
        items = [
            self.lfchar + self.htchar * (indent + 1) + (self.types[type(item) if type(item) in self.types else object])(self, item, indent + 1)
            for item in value
        ]
        return '(%s)' % (','.join(items) + self.lfchar + self.htchar * indent)

To initialize it :

pretty = Formatter()

It can support the addition of formatters for defined types, you simply need to make a function for that like this one and bind it to the type you want with set_formater :

from collections import OrderedDict

def format_ordereddict(self, value, indent):
    items = [
        self.lfchar + self.htchar * (indent + 1) +
        "(" + repr(key) + ', ' + (self.types[
            type(value[key]) if type(value[key]) in self.types else object
        ])(self, value[key], indent + 1) + ")"
        for key in value
    ]
    return 'OrderedDict([%s])' % (','.join(items) +
           self.lfchar + self.htchar * indent)
pretty.set_formater(OrderedDict, format_ordereddict)

For historical reasons, I keep the previous pretty printer which was a function instead of a class, but they both can be used the same way, the class version simply permit much more :

def pretty(value, htchar='\t', lfchar='\n', indent=0):
    nlch = lfchar + htchar * (indent + 1)
    if type(value) is dict:
        items = [
            nlch + repr(key) + ': ' + pretty(value[key], htchar, lfchar, indent + 1)
            for key in value
        ]
        return '{%s}' % (','.join(items) + lfchar + htchar * indent)
    elif type(value) is list:
        items = [
            nlch + pretty(item, htchar, lfchar, indent + 1)
            for item in value
        ]
        return '[%s]' % (','.join(items) + lfchar + htchar * indent)
    elif type(value) is tuple:
        items = [
            nlch + pretty(item, htchar, lfchar, indent + 1)
            for item in value
        ]
        return '(%s)' % (','.join(items) + lfchar + htchar * indent)
    else:
        return repr(value)

To use it :

>>> a = {'list':['a','b',1,2],'dict':{'a':1,2:'b'},'tuple':('a','b',1,2),'function':pretty,'unicode':u'\xa7',("tuple","key"):"valid"}
>>> a
{'function': <function pretty at 0x7fdf555809b0>, 'tuple': ('a', 'b', 1, 2), 'list': ['a', 'b', 1, 2], 'dict': {'a': 1, 2: 'b'}, 'unicode': u'\xa7', ('tuple', 'key'): 'valid'}
>>> print(pretty(a))
{
    'function': <function pretty at 0x7fdf555809b0>,
    'tuple': (
        'a',
        'b',
        1,
        2
    ),
    'list': [
        'a',
        'b',
        1,
        2
    ],
    'dict': {
        'a': 1,
        2: 'b'
    },
    'unicode': u'\xa7',
    ('tuple', 'key'): 'valid'
}

Compared to other versions :

• This solution looks directly for object type, so you can pretty print almost everything, not only list or dict.
• Doesn't have any dependancy.
• Everything is put inside a string, so you can do whatever you want with it.
• The class and the function has been tested and works with Python 2.7 and 3.4.
• You can have all type of objects inside, this is their representations and not theirs contents that being put in the result (so string have quotes, Unicode string are fully represented ...).
• With the class version, you can add formatting for every object type you want or change them for already defined ones.
• key can be of any valid type.
• Indent and Newline character can be changed for everything we'd like.
• Dict, List and Tuples are pretty printed.

To answer your second question, yes, you can cast the List<?> as a List<Object> or a List<T> of any type, since the ? (Wildcard) parameter indicates that the list contains a homogenous collection of an any Object. However, there's no way to know at compile what the type is since it's part of the exported API only - meaning you can't see what's being inserted into the List<?>.

Here's how you would make the cast:

List<?> wildcardList = methodThatReturnsWildcardList();
// generates Unchecked cast compiler warning
List<Object> objectReference = (List<Object>)wildcardList;

In this case you can ignore the warning because in order for an object to be used in a generic class it must be a subtype of Object. Let's pretend that we're trying to cast this as a List<Integer> when it actually contains a collection of Strings.

// this code will compile safely
List<?> wildcardList = methodThatReturnsWildcardList();
List<Integer> integerReference = (List<Integer>)wildcardList;

// this line will throw an invalid cast exception for any type other than Integer
Integer myInteger = integerRefence.get(0);

Remember: generic types are erased at runtime. You won't know what the collection contains, but you can get an element and call .getClass() on it to determine its type.

Class objectClass = wildcardList.get(0).getClass();

Also useful:

let multiLineString = """
                  Line One
                  Line Two
                  Line Three
                  """

• Makes the code read more understandable
• Allows copy pasting

In your head element add

<script type="text/javascript" src="myscript.js"></script>

If using command line tools, do

sdkmanager 'extras;google;m2repository'
sdkmanager 'extras;android;m2repository'

Did you try using t.Text?

if you want to compute differences between two known dates, use total_seconds like this:

import datetime as dt

a = dt.datetime(2013,12,30,23,59,59)
b = dt.datetime(2013,12,31,23,59,59)

(b-a).total_seconds()

86400.0

#note that seconds doesn't give you what you want:
(b-a).seconds

0

Just a small correction to the first answer in this thread.

Even for Stack, you need to create new object with generics if you are using Stack from java util packages.

Right usage:
    Stack<Integer> s = new Stack<Integer>();
    Stack<String> s1 = new Stack<String>();

    s.push(7);
    s.push(50);

    s1.push("string");
    s1.push("stack");

if used otherwise, as mentioned in above post, which is:

    /*
    Stack myStack = new Stack();
    // add any type of elements (String, int, etc..)
    myStack.push("Hello");
    myStack.push(1);
    */

Although this code works fine, has unsafe or unchecked operations which results in error.

        driver.findElement(By.xpath("(//h3[@class='r']/a)[3]")).click();
        driver.manage().timeouts().implicitlyWait(30,TimeUnit.SECONDS); 
    }
}

I know this question is quite old, but I have not seen this solution here before:

If you rewrite the <body> tag to.

<body oncontextmenu="return false;">

you can prevent the right click without using javascript.

However, you can't prevent keyboard shortcuts with HTML. For this, you must use Javascript.

Based on different answers but mainly on this, this works for what I need:

UIImage *image1 = ...; // The image from where you want a pixel data
int pixelX = ...; // The X coordinate of the pixel you want to retrieve
int pixelY = ...; // The Y coordinate of the pixel you want to retrieve

uint32_t pixel1; // Where the pixel data is to be stored
CGContextRef context1 = CGBitmapContextCreate(&pixel1, 1, 1, 8, 4, CGColorSpaceCreateDeviceRGB(), kCGImageAlphaNoneSkipFirst);
CGContextDrawImage(context1, CGRectMake(-pixelX, -pixelY, CGImageGetWidth(image1.CGImage), CGImageGetHeight(image1.CGImage)), image1.CGImage);
CGContextRelease(context1);

As a result of this lines, you will have a pixel in AARRGGBB format with alpha always set to FF in the 4 byte unsigned integer pixel1.

I've made a mistake in the last my post. This is working example for how to pass additional argument in callback function:

function custom_func(p1,p2) {
    $.post(AJAX_FILE_PATH,{op:'dosomething',p1:p1},
        function(data){
            return function(){
                alert(data);
                alert(p2);
            }(data,p2)
        }
    );
    return false;
}

You should check out if there is no DBMS administration and development platform working on your database (like pgAdmin), as this is probably the most popular cause of this error. If there is - commit the changes done and the problem is gone.

IValueConverter implementation can be used. Converter class which takes inheritance from IValueConverter takes some parameters like value (percentage) and parameter (parent's width) and returns desired width value. In XAML file, component's width is set with the desired value:

public class SizePercentageConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        if (parameter == null)
            return 0.7 * value.ToDouble();

        string[] split = parameter.ToString().Split('.');
        double parameterDouble = split[0].ToDouble() + split[1].ToDouble() / (Math.Pow(10, split[1].Length));
        return value.ToDouble() * parameterDouble;
    }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
        // Don't need to implement this
        return null;
    }
}

XAML:

<UserControl.Resources>
    <m:SizePercentageConverter x:Key="PercentageConverter" />
</UserControl.Resources>

<ScrollViewer VerticalScrollBarVisibility="Auto"
          HorizontalScrollBarVisibility="Disabled"
          Width="{Binding Converter={StaticResource PercentageConverter}, RelativeSource={RelativeSource Mode=FindAncestor,AncestorType={x:Type Border}},Path=ActualWidth}"
          Height="{Binding Converter={StaticResource PercentageConverter}, ConverterParameter=0.6, RelativeSource={RelativeSource Mode=FindAncestor,AncestorType={x:Type Border}},Path=ActualHeight}">
....
</ScrollViewer>

Compatibility with older browsers can be a drag, so be adviced.

If that is not a problem then go ahead. Run the snippet. Go to full page view and resize. Center will resize itself with no changes to the left or right divs.

Change left and right values to meet your requirement.

Thank you.

For the instance of

render :json => @projects, :include => :tasks

You are stating that you want to render @projects as JSON, and include the association tasks on the Project model in the exported data.

For the instance of

render :json => @projects, :callback => 'updateRecordDisplay'

You are stating that you want to render @projects as JSON, and wrap that data in a javascript call that will render somewhat like:

updateRecordDisplay({'projects' => []})

This allows the data to be sent to the parent window and bypass cross-site forgery issues.

. "$PSScriptRoot\MyFunctions.ps1" MyA1Func

Availalbe starting in v3, before that see How can I get the file system location of a PowerShell script?. It is VERY common.

P.S. I don't subscribe to the 'everything is a module' rule. My scripts are used by other developers out of GIT, so I don't like to put stuff in specific a place or modify system environment variables before my script will run. It's just a script (or two, or three).

you have to use the To_Date() function to convert the string to date ! http://www.techonthenet.com/oracle/functions/to_date.php

Below are the steps to install Android Studio in Ubuntu system:

1. Install JDK 6 or later

First, install Oracle JDK 8 (although you could also choose OpenJDK but it has some UI/performance issues) using WebUpd8 PPA.

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer
sudo apt-get install oracle-java8-set-default

To make sure, it’s installed successfully, open a terminal and type (you should get the version number of the jdk you’ve installed e.g javac 1.8.0_11)

javac -version

2. Download and install Android Studio

Download the Android Studio package for Linux and extract it somewhere (e.g home directory). Then type :

cd android-studio/bin
./studio.sh

3. Install SDK Platforms

You need to install some SDK before you jump into building android apps. Click on Configure -> SDK Manager to open Android SDK Manager. Select the latest API (to test against target build, e.g API 19 (Android 4.4.2)) and some packages in Extras (Android Support Library and Android Support Repository). Then install the selected packages.

Actually, a concise rule for Python Scope resolution, from Learning Python, 3rd. Ed.. (These rules are specific to variable names, not attributes. If you reference it without a period, these rules apply.)

LEGB Rule

• Local — Names assigned in any way within a function (def or lambda), and not declared global in that function

• Enclosing-function — Names assigned in the local scope of any and all statically enclosing functions (def or lambda), from inner to outer

• Global (module) — Names assigned at the top-level of a module file, or by executing a global statement in a def within the file

• Built-in (Python) — Names preassigned in the built-in names module: open, range, SyntaxError, etc

So, in the case of

code1
class Foo:
    code2
    def spam():
        code3
        for code4:
            code5
            x()

The for loop does not have its own namespace. In LEGB order, the scopes would be

• L: Local in def spam (in code3, code4, and code5)
• E: Any enclosing functions (if the whole example were in another def)
• G: Were there any x declared globally in the module (in code1)?
• B: Any builtin x in Python.

x will never be found in code2 (even in cases where you might expect it would, see Antti's answer or here).

check if file exist in side the document/catchimage path :

NSString *stringPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)objectAtIndex:0];
NSString *tempName = [NSString stringWithFormat:@"%@/catchimage/%@.png",stringPath,@"file name"];
NSLog(@"%@",temName);
if([[NSFileManager defaultManager] fileExistsAtPath:temName]){
    // ur code here
} else {
    // ur code here** 
}

Just use the classic == operator:

>>> [0,1,2] == [0,1,2]
True
>>> [0,1,2] == [0,2,1]
False
>>> [0,1] == [0,1,2]
False

Lists are equal if elements at the same index are equal. Ordering is taken into account then.

No need for scripts or other 'tricks': openssl and ssh-keygen are enough. I'm assuming no password for the keys (which is bad).

Generate an RSA pair

All the following methods give an RSA key pair in the same format

1. With openssl (man genrsa)

   openssl genrsa -out dummy-genrsa.pem 2048
   

   In OpenSSL v1.0.1 genrsa is superseded by genpkey so this is the new way to do it (man genpkey):

   openssl genpkey -algorithm RSA -out dummy-genpkey.pem -pkeyopt rsa_keygen_bits:2048
   

2. With ssh-keygen

   ssh-keygen -t rsa -b 2048 -f dummy-ssh-keygen.pem -N '' -C "Test Key"
   

Converting DER to PEM

If you have an RSA key pair in DER format, you may want to convert it to PEM to allow the format conversion below:

Generation:

openssl genpkey -algorithm RSA -out genpkey-dummy.cer -outform DER -pkeyopt rsa_keygen_bits:2048

Conversion:

openssl rsa -inform DER -outform PEM -in genpkey-dummy.cer -out dummy-der2pem.pem

Extract the public key from the PEM formatted RSA pair

2. in PEM format:

   openssl rsa -in dummy-xxx.pem -pubout
   

3. in OpenSSH v2 format see:

   ssh-keygen -y -f dummy-xxx.pem

You can't install and run in one go - but you can certainly use adb to start your already installed application. Use adb shell am start to fire an intent - you will need to use the correct intent for your application though. A couple of examples:

adb shell am start -a android.intent.action.MAIN -n com.android.settings/.Settings 

will launch Settings, and

adb shell am start -a android.intent.action.MAIN -n com.android.browser/.BrowserActivity 

will launch the Browser. If you want to point the Browser at a particular page, do this

adb shell am start -a android.intent.action.VIEW -n com.android.browser/.BrowserActivity http://www.google.co.uk

If you don't know the name of the activities in the APK, then do this

aapt d xmltree <path to apk> AndroidManifest.xml

the output content will includes a section like this:

   E: activity (line=32)
    A: android:theme(0x01010000)=@0x7f080000
    A: android:label(0x01010001)=@0x7f070000
    A: android:name(0x01010003)="com.anonymous.MainWindow"
    A: android:launchMode(0x0101001d)=(type 0x10)0x3
    A: android:screenOrientation(0x0101001e)=(type 0x10)0x1
    A: android:configChanges(0x0101001f)=(type 0x11)0x80
    E: intent-filter (line=33)
      E: action (line=34)
        A: android:name(0x01010003)="android.intent.action.MAIN"
        XE: (line=34)

That tells you the name of the main activity (MainWindow), and you can now run

adb shell am start -a android.intent.action.MAIN -n com.anonymous/.MainWindow

Depending on if your regex flavor supports it, I might use:

\b[A-Z]{2}\d{6}\b    # Ensure there are "word boundaries" on either side, or

(?<![A-Z])[A-Z]{2}\d{6}(?!\d) # Ensure there isn't a uppercase letter before
                              # and that there is not a digit after

I think you can use the nrows parameter. From the docs:

nrows : int, default None

    Number of rows of file to read. Useful for reading pieces of large files

which seems to work. Using one of the standard large test files (988504479 bytes, 5344499 lines):

In [1]: import pandas as pd

In [2]: time z = pd.read_csv("P00000001-ALL.csv", nrows=20)
CPU times: user 0.00 s, sys: 0.00 s, total: 0.00 s
Wall time: 0.00 s

In [3]: len(z)
Out[3]: 20

In [4]: time z = pd.read_csv("P00000001-ALL.csv")
CPU times: user 27.63 s, sys: 1.92 s, total: 29.55 s
Wall time: 30.23 s

That is because in Python 3, they have replaced the print statement with the print function.

The syntax is now more or less the same as before, but it requires parens:

From the "what's new in python 3" docs:

Old: print "The answer is", 2*2
New: print("The answer is", 2*2)

Old: print x,           # Trailing comma suppresses newline
New: print(x, end=" ")  # Appends a space instead of a newline

Old: print              # Prints a newline
New: print()            # You must call the function!

Old: print >>sys.stderr, "fatal error"
New: print("fatal error", file=sys.stderr)

Old: print (x, y)       # prints repr((x, y))
New: print((x, y))      # Not the same as print(x, y)!

You could write a windows service that does nothing but execute your batch file. Since services run in their own desktop session, the command window won't be visible by the user.

After the first if statement instead of typing "if" type "elif" and then it should work.

Ex.

`    while 1:
    date=input("Example: March 21 | What is the date? ")
if date=="June 21":
    sd="23.5° North Latitude
elif date=="March 21" | date=="September 21":
    sd="0° Latitude"
elif date=="December 21":
    sd="23.5° South Latitude"
elif sd:
    print sd `

HttpPost is deprecated by Android Api Level 22. So, Use HttpUrlConnection for further.

public static String makeRequest(String uri, String json) {
    HttpURLConnection urlConnection;
    String url;
    String data = json;
    String result = null;
    try {
        //Connect 
        urlConnection = (HttpURLConnection) ((new URL(uri).openConnection()));
        urlConnection.setDoOutput(true);
        urlConnection.setRequestProperty("Content-Type", "application/json");
        urlConnection.setRequestProperty("Accept", "application/json");
        urlConnection.setRequestMethod("POST");
        urlConnection.connect();

        //Write
        OutputStream outputStream = urlConnection.getOutputStream();
        BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(outputStream, "UTF-8"));
        writer.write(data);
        writer.close();
        outputStream.close();

        //Read
        BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(urlConnection.getInputStream(), "UTF-8"));

        String line = null;
        StringBuilder sb = new StringBuilder();

        while ((line = bufferedReader.readLine()) != null) {
            sb.append(line);
        }

        bufferedReader.close();
        result = sb.toString();

    } catch (UnsupportedEncodingException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
    return result;
}

If anyone is strugling with the same problem I solved it by adding @EntityScan in my main class. Just add your model package to the basePackages property.

If the content has more than 1 line, adding a bottom border won't help. In that case you'll have to use,

text-decoration: underline;
text-decoration-style: dotted;

If you want more breathing space in between the text and the line, simply use,

text-underline-position: under;

Something like this worked for me (references columns C and D from the row 8 till the end of the columns, in Excel 2013 if relevant):

=SUMIFS(INDIRECT(ADDRESS(ROW(D$8), COLUMN())&":"&ADDRESS(ROWS($C:$C), COLUMN())),INDIRECT("C$8:C"&ROWS($C:$C)),$C$2)

I got the same error when trying to compile a Go package on Debian 9.8:

# pkg-config --cflags  -- libssl libcrypto
Package libssl was not found in the pkg-config search path.
Perhaps you should add the directory containing `libssl.pc'

The thing is that pkg-config searches for package meta-information in .pc files. Such files come from the dev package. So, even though I had libssl installed, I still got the error. It was resolved by running:

sudo apt-get install libssl-dev

Swift:

self.navigationController?.navigationBar.barTintColor = UIColor.red
self.navigationController?.navigationBar.isTranslucent = false

If you use lombok, you can get that error if you screw up naming of @JsonDeserialize, for example:

@Value
@Builder(toBuilder = true)
@JsonDeserialize(builder = SomeClass.SomeOtherClassBuilder.class)
public class SomeClass {
    ...
    public static class SomeOtherClassBuilder {
        ...
    }
}

It should be:

@Value
@Builder(toBuilder = true)
@JsonDeserialize(builder = SomeClass.SomeClassBuilder.class)
public class SomeClass {
    ...
    public static class SomeClassBuilder {
        ...
    }
}

It is very easy to do that when you do refactoring of class name and forget about Builder... and then you have many hours of joy while you search for reason of error, while having as help only extremely unhelpful exception message.

In my case I had .Net core SDK 3.1.403 was installed. So I installed the corresponding .Net Core Windows Server Hosting which is .NET core 3.1.9 - Windows Server Hosting.

To rebuild use:

ALTER INDEX __NAME_OF_INDEX__ ON __NAME_OF_TABLE__ REBUILD

or to reorganize use:

ALTER INDEX __NAME_OF_INDEX__ ON __NAME_OF_TABLE__ REORGANIZE

Reorganizing should be used at lower (<30%) fragmentations but only rebuilding (which is heavier to the database) cuts the fragmentation down to 0%.

You can get only visible View from ListView because row views in ListView are reuseable. If you use mListView.getChildAt(0) you get first visible view. This view is associated with item from adapter at position mListView.getFirstVisiblePosition().

You should do this with the help of AsyncTask (an intelligent backround thread) and ProgressDialog

AsyncTask enables proper and easy use of the UI thread. This class allows to perform background operations and publish results on the UI thread without having to manipulate threads and/or handlers.

An asynchronous task is defined by a computation that runs on a background thread and whose result is published on the UI thread. An asynchronous task is defined by 3 generic types, called Params, Progress and Result, and 4 steps, called begin, doInBackground, processProgress and end.

The 4 steps

When an asynchronous task is executed, the task goes through 4 steps:

onPreExecute(), invoked on the UI thread immediately after the task is executed. This step is normally used to setup the task, for instance by showing a progress bar in the user interface.

doInBackground(Params...), invoked on the background thread immediately after onPreExecute() finishes executing. This step is used to perform background computation that can take a long time. The parameters of the asynchronous task are passed to this step. The result of the computation must be returned by this step and will be passed back to the last step. This step can also use publishProgress(Progress...) to publish one or more units of progress. These values are published on the UI thread, in the onProgressUpdate(Progress...) step.

onProgressUpdate(Progress...), invoked on the UI thread after a call to publishProgress(Progress...). The timing of the execution is undefined. This method is used to display any form of progress in the user interface while the background computation is still executing. For instance, it can be used to animate a progress bar or show logs in a text field.

onPostExecute(Result), invoked on the UI thread after the background computation finishes. The result of the background computation is passed to this step as a parameter. Threading rules

There are a few threading rules that must be followed for this class to work properly:

The task instance must be created on the UI thread. execute(Params...) must be invoked on the UI thread. Do not call onPreExecute(), onPostExecute(Result), doInBackground(Params...), onProgressUpdate(Progress...) manually. The task can be executed only once (an exception will be thrown if a second execution is attempted.)

Example code
What the adapter does in this example is not important, more important to understand that you need to use AsyncTask to display a dialog for the progress.

private class PrepareAdapter1 extends AsyncTask<Void,Void,ContactsListCursorAdapter > {
    ProgressDialog dialog;
    @Override
    protected void onPreExecute() {
        dialog = new ProgressDialog(viewContacts.this);
        dialog.setMessage(getString(R.string.please_wait_while_loading));
        dialog.setIndeterminate(true);
        dialog.setCancelable(false);
        dialog.show();
    }
    /* (non-Javadoc)
     * @see android.os.AsyncTask#doInBackground(Params[])
     */
    @Override
    protected ContactsListCursorAdapter doInBackground(Void... params) {
        cur1 = objItem.getContacts();
        startManagingCursor(cur1);

        adapter1 = new ContactsListCursorAdapter (viewContacts.this,
                R.layout.contact_for_listitem, cur1, new String[] {}, new int[] {});

        return adapter1;
    }

    protected void onPostExecute(ContactsListCursorAdapter result) {
        list.setAdapter(result);
        dialog.dismiss();
    }
}

Prior to HTML5, input type="text" simply means a field to insert free text, regardless of what you want it be. that is the job of validations you would have to do in order to guarantee the user enters a valid number

If you're using HTML5, you can use the new input types, one of which is number that automatically validates the text input, and forces it to be a number

keep in mind though, that if you're building a server side app (php for example) you will still have to validate the input on that side (make sure it is really a number) since it's pretty easy to hack the html and change the input type, removing the browser validation

It's likely that your output encoding is set to ASCII. Try using this before sending output:

Console.OutputEncoding = System.Text.Encoding.UTF8;

(MSDN link to supporting documentation.)

And here's a little console test app you may find handy:

C#

using System;

It's also possible that your choice of Console font does not support that particular character. Click on the Windows Tool-bar Menu (icon like C:.) and select Properties -> Font. Try some other fonts to see if they display your character properly:

One important thing I missed from the tutorials for a while (stolen from http://www.tramontana.co.hu/wix/lesson4.php) which resulted in the "Another version of this product is already installed" errors:

*Small updates mean small changes to one or a few files where the change doesn't warrant changing the product version (major.minor.build). You don't have to change the Product GUID, either. Note that you always have to change the Package GUID when you create a new .msi file that is different from the previous ones in any respect. The Installer keeps track of your installed programs and finds them when the user wants to change or remove the installation using these GUIDs. Using the same GUID for different packages will confuse the Installer.

Minor upgrades denote changes where the product version will already change. Modify the Version attribute of the Product tag. The product will remain the same, so you don't need to change the Product GUID but, of course, get a new Package GUID.

Major upgrades denote significant changes like going from one full version to another. Change everything: Version attribute, Product and Package GUIDs.

You can achieve it using custom log4j appender.
MaxNumberOfDays - possibility to set amount of days of rotated log files.
CompressBackups - possibility to archive old logs with zip extension.

I don't know if there's a way to get a clean build via the UI, but it's easy to do from the commandline using gradle wrapper. From the root directory of your project:

./gradlew clean 

This is the check on which it fails:

• https://github.com/scikit-learn/scikit-learn/blob/0.17.X/sklearn/utils/validation.py#L51

Which says

def _assert_all_finite(X):
    """Like assert_all_finite, but only for ndarray."""
    X = np.asanyarray(X)
    # First try an O(n) time, O(1) space solution for the common case that
    # everything is finite; fall back to O(n) space np.isfinite to prevent
    # false positives from overflow in sum method.
    if (X.dtype.char in np.typecodes['AllFloat'] and not np.isfinite(X.sum())
            and not np.isfinite(X).all()):
        raise ValueError("Input contains NaN, infinity"
                         " or a value too large for %r." % X.dtype)

So make sure that you have non NaN values in your input. And all those values are actually float values. None of the values should be Inf either.

#include <iostream>
#include <string>
#include <sstream>
using namespace std;
int main()
{
    std::string input = "abc,def,   ghi";
    std::istringstream ss(input);
    std::string token;
    size_t pos=-1;
    while(ss>>token) {
      while ((pos=token.rfind(',')) != std::string::npos) {
        token.erase(pos, 1);
      }
      std::cout << token << '\n';
    }
}

Courtesy of Microsoft Excel: 

Using standard JSF API, add the client ID to PartialViewContext#getRenderIds().

FacesContext.getCurrentInstance().getPartialViewContext().getRenderIds().add("foo:bar");

Using PrimeFaces specific API, use PrimeFaces.Ajax#update().

PrimeFaces.current().ajax().update("foo:bar");

Or if you're not on PrimeFaces 6.2+ yet, use RequestContext#update().

RequestContext.getCurrentInstance().update("foo:bar");

If you happen to use JSF utility library OmniFaces, use Ajax#update().

Ajax.update("foo:bar");

Regardless of the way, note that those client IDs should represent absolute client IDs which are not prefixed with the NamingContainer separator character like as you would do from the view side on.

No solutions worked for me from here, so I found another one:

set +e
find "./csharp/Platform.$REPOSITORY_NAME/obj" -type f -iname "*.cs" -delete
find "./csharp/Platform.$REPOSITORY_NAME.Tests/obj" -type f -iname "*.cs" -delete
set -e

This is useful for CI & CD. This way the error messages are printed but the whole script continues to execute.

If the starting cell of the range and of the key is static, the solution can be very simple:

Range("A3").Select
Range(Selection, Selection.End(xlToRight)).Select
Range(Selection, Selection.End(xlDown)).Select
Selection.Sort key1:=Range("B3", Range("B3").End(xlDown)), _
order1:=xlAscending, Header:=xlNo

If the data is stored as INT, you may want to try

Average = (R1 + R2 + R3 + R4 + R5) / 5.0

If you want to hide gridlines but want to show yAxes, you can set:

yAxes: [{...
         gridLines: {
                        drawBorder: true,
                        display: false
                    }
       }]

I'm working on this Java EE application that is composed of a Web module that uses an EJB module. The web module calls the EJB module remotely and passes a POJO that implements Serializable as an argument.

This POJO's class was packaged inside the EJB jar and inside it's own jar in the WEB-INF/lib of the web module. They're actually the same class, but when I package the EJB module I unpack this POJO's jar to pack it together with the EJB module.

The call to the EJB was failing with the Exception below because I hadn't declared its serialVersionUID:

Caused by: java.io.IOException: Mismatched serialization UIDs : Source
 (Rep.
 IDRMI:com.hordine.pedra.softbudget.domain.Budget:5CF7CE11E6810A36:04A3FEBED5DA4588)
 = 04A3FEBED5DA4588 whereas Target (Rep. ID RMI:com.hordine.pedra.softbudget.domain.Budget:7AF5ED7A7CFDFF31:6227F23FA74A9A52)
 = 6227F23FA74A9A52

I needed an overload for:

public ActionResult Index(string i);
public ActionResult Index(int groupId, int itemId);

There were few enough arguments where I ended up doing this:

public ActionResult Index(string i, int? groupId, int? itemId)
{
    if (!string.IsNullOrWhitespace(i))
    {
        // parse i for the id
    }
    else if (groupId.HasValue && itemId.HasValue)
    {
        // use groupId and itemId for the id
    }
}

It's not a perfect solution, especially if you have a lot of arguments, but it works well for me.

please check the below code for more details

        System.out.println(Arrays.toString(strArray));

There are lots of explanation of Jmeter Summary, I have been using this tool from quite some time for generating performance testing report with relevant data. The explanation available on below link is right from the field experience:

Jmeter:Understanding Summary Report

This is one of the most useful report generated by Jmeter to undertstand the load test result.

# Label: Name of HTTP sample request send to server

# Samples : This Captures the total number of samples pushed to server. Suppose you put a Loop Controller to run it 5 times this particular request and then 2 iteration(Called Loop Count in Thread Group)is set and load test is run for 100 users, then the count that will be displayed here .... 1*5*2 * 100 =1000. Total = total number of samples send to server during entire run.

# Average : It's an average response time for a particular http request. This response time is in millisecond, and an average for 5 loops in two iteration for 100 users. Total = Average of total average of samples, means add all averages for all samples and divide by number of samples

# Min : Minmum time spend by sample requests send for this label. The total equals to the minimum time across all samples.

# Max : Maximum tie spend by sample requests send for this label The total equals to the maxmimum time across all samples.

# Std. Dev. : Knowing the standard deviation of your data set tells you how densely the data points are clustered around the mean. The smaller the standard deviation, the more consistent the data. Standard deviation should be less than or equal to half of the average time for a label. If it is more than that, then it means that something is wrong. you need to figure out the problem and fix it. https://en.wikipedia.org/wiki/Standard_deviation Total is euqals to highest deviation across all samples.

# Error: Total percentage of erros found for a particular sample request. 0.0% shows that all requests completed successfully. Total equals to percentage of errors samples in all samples (Total Samples)

# Throughput: Hits/sec, or total number of request per unit of time(sec, mins, hr) send to server during test.

endTime = lastSampleStartTime + lastSampleLoadTime
startTime = firstSampleStartTime
converstion = unit time conversion value
Throughput = Numrequests / ((endTime - startTime)*conversion)

# KB/sec : Its mesuring throughput rate in Kilobytes per second.

# Avg. Bytes: Avegare of total bytes of data downloaded from server. Totals is average bytes across all samples.

Try this:

<img v-bind:src="'/media/avatars/' + joke.avatar" /> 

Don't forget single quote around your path string. also in your data check you have correctly defined image variable.

joke: {
  avatar: 'image.jpg'
}

The builtin json module got included in Python 2.6. Any projects that support versions of Python < 2.6 need to have a fallback. In many cases, that fallback is simplejson.

Range("A1").value = Environ("Username")

This is better than Application.Username, which doesn't always supply the Windows username. Thanks to Kyle for pointing this out.

• Application Username is the name of the User set in Excel > Tools > Options
• Environ("Username") is the name you registered for Windows; see Control Panel >System

See man git merge (HOW TO RESOLVE CONFLICTS):

After seeing a conflict, you can do two things:

• Decide not to merge. The only clean-ups you need are to reset the index file to the HEAD commit to reverse 2. and to clean up working tree changes made by 2. and 3.; git-reset --hard can be used for this.

• Resolve the conflicts. Git will mark the conflicts in the working tree. Edit the files into shape and git add them to the index. Use git commit to seal the deal.

And under TRUE MERGE (to see what 2. and 3. refers to):

When it is not obvious how to reconcile the changes, the following happens:

1. The HEAD pointer stays the same.

2. The MERGE_HEAD ref is set to point to the other branch head.

3. Paths that merged cleanly are updated both in the index file and in your working tree.

4. ...

So: use git reset --hard if you want to remove the stash changes from your working tree, or git reset if you want to just clean up the index and leave the conflicts in your working tree to merge by hand.

Under man git stash (OPTIONS, pop) you can read in addition:

Applying the state can fail with conflicts; in this case, it is not removed from the stash list. You need to resolve the conflicts by hand and call git stash drop manually afterwards.

You normally define your connection strings in Web.config. After generating the edmx the connection string will get stored in the App.Config. If you want to change the connection string go to the app.config and remove all the connection strings. Now go to the edmx, right click on the designer surface, select Update model from database, choose the connection string from the dropdown, Click next, Add or Refresh (select what you want) and finish.

In the output window it will show something like this,

Generated model file: UpostDataModel.edmx. Loading metadata from the database took 00:00:00.4258157. Generating the model took 00:00:01.5623765. Added the connection string to the App.Config file.

I note you suggested this formula

=IF(ISNUMBER(FIND("RuhrP";F9));LOOKUP(A9;Ruhrpumpen!A$5:A$100;Ruhrpumpen!I$5:I$100);"")

.....but LOOKUP isn't appropriate here because I assume you want an exact match (LOOKUP won't guarantee that and also data in lookup range has to be sorted), so VLOOKUP or INDEX/MATCH would be better....and you can also use IFERROR to avoid the IF function, i.e

=IFERROR(VLOOKUP(A9;Ruhrpumpen!A$5:Z$100;9;0);"")

Note: VLOOKUP always looks up the lookup value (A9) in the first column of the "table array" and returns a value from the nth column of the "table array" where n is defined by col_index_num, in this case 9

INDEX/MATCH is sometimes more flexible because you can explicitly define the lookup column and the return column (and return column can be to the left of the lookup column which can't be the case in VLOOKUP), so that would look like this:

=IFERROR(INDEX(Ruhrpumpen!I$5:I$100;MATCH(A9;Ruhrpumpen!A$5:A$100;0));"")

INDEX/MATCH also allows you to more easily return multiple values from different columns, e.g. by using $ signs in front of A9 and the lookup range Ruhrpumpen!A$5:A$100, i.e.

=IFERROR(INDEX(Ruhrpumpen!I$5:I$100;MATCH($A9;Ruhrpumpen!$A$5:$A$100;0));"")

this version can be dragged across to get successive values from column I, column J, column K etc.....

hash  = { :a => ["a", "b", "c"], :b => ["b", "c"] }
hash.values #=> [["a","b","c"],["b","c"]]

You can try:

#!/bin/bash
d=$(date +%Y-%m-%d)
echo "$d"

Solution

Use nested flex containers.

Get rid of percentage heights. Get rid of table properties. Get rid of vertical-align. Avoid absolute positioning. Just stick with flexbox all the way through.

Apply display: flex to the flex item (.item), making it a flex container. This automatically sets align-items: stretch, which tells the child (.item-inner) to expand the full height of the parent.

Important: Remove specified heights from flex items for this method to work. If a child has a height specified (e.g. height: 100%), then it will ignore the align-items: stretch coming from the parent. For the stretch default to work, the child's height must compute to auto (full explanation).

Try this (no changes to HTML):

.container {_x000D_
    display: flex;_x000D_
    flex-direction: column;_x000D_

Explanation

My problem is that .item-inner { height: 100% } is not working in webkit (Chrome).

It's not working because you're using percentage height in a way that doesn't conform with the traditional implementation of the spec.

10.5 Content height: the height property

percentage
Specifies a percentage height. The percentage is calculated with respect to the height of the generated box's containing block. If the height of the containing block is not specified explicitly and this element is not absolutely positioned, the value computes to auto.

auto
The height depends on the values of other properties.

In other words, for percentage height to work on an in-flow child, the parent must have a set height.

In your code, the top-level container has a defined height: .container { height: 20em; }

The third-level container has a defined height: .item-inner { height: 100%; }

But between them, the second-level container – .item – does not have a defined height. Webkit sees that as a missing link.

.item-inner is telling Chrome: give me height: 100%. Chrome looks to the parent (.item) for reference and responds: 100% of what? I don't see anything (ignoring the flex: 1 rule that is there). As a result, it applies height: auto (content height), in accordance with the spec.

Firefox, on the other hand, now accepts a parent's flex height as a reference for the child's percentage height. IE11 and Edge accept flex heights, as well.

Also, Chrome will accept flex-grow as an adequate parent reference if used in conjunction with flex-basis (any numerical value works (auto won't), including flex-basis: 0). As of this writing, however, this solution fails in Safari.

#outer {_x000D_
  display: flex;_x000D_
  flex-direction: column;_x000D_
  height: 300px;_x000D_
  background-color: white;_x000D_
  border: 1px solid red;_x000D_
}_x000D_
#middle {_x000D_
  flex-grow: 1;_x000D_
  flex-basis: 1px;_x000D_
  background-color: yellow;_x000D_
}_x000D_
#inner {_x000D_
  height: 100%;_x000D_
  background-color: lightgreen;_x000D_
}

<div id="outer">_x000D_
  <div id="middle">_x000D_
    <div id="inner">_x000D_
      INNER_x000D_
    </div>_x000D_
  </div>_x000D_
</div>

Four Solutions

1. Specify a height on all parent elements

A reliable cross-browser solution is to specify a height on all parent elements. This prevents missing links, which Webkit-based browsers consider a violation of the spec.

Note that min-height and max-height are not acceptable. It must be the height property.

More details here: Working with the CSS height property and percentage values

2. CSS Relative & Absolute Positioning

Apply position: relative to the parent and position: absolute to the child.

Size the child with height: 100% and width: 100%, or use the offset properties: top: 0, right: 0, bottom: 0, left: 0.

With absolute positioning, percentage height works without a specified height on the parent.

3. Remove unnecessary HTML containers (recommended)

Is there a need for two containers around button? Why not remove .item or .item-inner, or both? Although button elements sometimes fail as flex containers, they can be flex items. Consider making button a child of .container or .item, and removing gratuitous mark-up.

Here's an example:

.container {_x000D_
    height: 20em;_x000D_
    display: flex;_x000D_
    flex-direction: column;_x000D_
    border: 5px solid black_x000D_
}_x000D_
_x000D_
a {_x000D_
    flex: 1;_x000D_
    background: orange;_x000D_
    border-bottom: 1px solid white;_x000D_
    display: flex;                   /* nested flex container (for aligning text) */_x000D_
    align-items: center;             /* center text vertically */_x000D_
    justify-content: center;         /* center text horizontally */_x000D_
}

<div class="container">_x000D_
    <a>Button</a>_x000D_
    <a>Button</a>_x000D_
    <a>Button</a>_x000D_
</div>

4. Nested Flex Containers (recommended)

Get rid of percentage heights. Get rid of table properties. Get rid of vertical-align. Avoid absolute positioning. Just stick with flexbox all the way through.

Apply display: flex to the flex item (.item), making it a flex container. This automatically sets align-items: stretch, which tells the child (.item-inner) to expand the full height of the parent.

Important: Remove specified heights from flex items for this method to work. If a child has a height specified (e.g. height: 100%), then it will ignore the align-items: stretch coming from the parent. For the stretch default to work, the child's height must compute to auto (full explanation).

Here is an example:

List<String> names;
names.add("toto");
names.add("Lala");
names.add("papa");
int index = names.indexOf("papa"); // index = 2

You could also use a session for passing small bits of info. You will need to have session_start(); at the top of the PHP pages that use the session else the variables will not be accessable

page1.php

<?php

   session_start();
   $_SESSION['superhero'] = "batman";

?>
<a href="page2.php" title="">Go to the other page</a>

page2.php

<?php 

   session_start(); // this NEEDS TO BE AT THE TOP of the page before any output etc
   echo $_SESSION['superhero'];

?>

You can use this to find and replace any special characters like in Worpress's slug

const regex = /[`~!@#$%^&*()-_+{}[\]\\|,.//?;':"]/g
let slug = label.replace(regex, '')

This definitely works and I use this wherever I need to add days to the current date:

Date.today + 5

Docker 1.9.0 and above

Use volume API

docker volume create --name hello
docker run -d -v hello:/container/path/for/volume container_image my_command

This means that the data-only container pattern must be abandoned in favour of the new volumes.

Actually the volume API is only a better way to achieve what was the data-container pattern.

If you create a container with a -v volume_name:/container/fs/path Docker will automatically create a named volume for you that can:

1. Be listed through the docker volume ls
2. Be identified through the docker volume inspect volume_name
3. Backed up as a normal directory
4. Backed up as before through a --volumes-from connection

The new volume API adds a useful command that lets you identify dangling volumes:

docker volume ls -f dangling=true

And then remove it through its name:

docker volume rm <volume name>

As @mpugach underlines in the comments, you can get rid of all the dangling volumes with a nice one-liner:

docker volume rm $(docker volume ls -f dangling=true -q)
# Or using 1.13.x
docker volume prune

Docker 1.8.x and below

The approach that seems to work best for production is to use a data only container.

The data only container is run on a barebones image and actually does nothing except exposing a data volume.

Then you can run any other container to have access to the data container volumes:

docker run --volumes-from data-container some-other-container command-to-execute

• Here you can get a good picture of how to arrange the different containers.
• Here there is a good insight on how volumes work.

In this blog post there is a good description of the so-called container as volume pattern which clarifies the main point of having data only containers.

Docker documentation has now the DEFINITIVE description of the container as volume/s pattern.

Following is the backup/restore procedure for Docker 1.8.x and below.

BACKUP:

sudo docker run --rm --volumes-from DATA -v $(pwd):/backup busybox tar cvf /backup/backup.tar /data

• --rm: remove the container when it exits
• --volumes-from DATA: attach to the volumes shared by the DATA container
• -v $(pwd):/backup: bind mount the current directory into the container; to write the tar file to
• busybox: a small simpler image - good for quick maintenance
• tar cvf /backup/backup.tar /data: creates an uncompressed tar file of all the files in the /data directory

RESTORE:

# Create a new data container
$ sudo docker run -v /data -name DATA2 busybox true
# untar the backup files into the new container?s data volume
$ sudo docker run --rm --volumes-from DATA2 -v $(pwd):/backup busybox tar xvf /backup/backup.tar
data/
data/sven.txt
# Compare to the original container
$ sudo docker run --rm --volumes-from DATA -v `pwd`:/backup busybox ls /data
sven.txt

Here is a nice article from the excellent Brian Goff explaining why it is good to use the same image for a container and a data container.

Use sprintf():

int someInt = 368;
char str[12];
sprintf(str, "%d", someInt);

All numbers that are representable by int will fit in a 12-char-array without overflow, unless your compiler is somehow using more than 32-bits for int. When using numbers with greater bitsize, e.g. long with most 64-bit compilers, you need to increase the array size—at least 21 characters for 64-bit types.

You could use the random.sample function from the standard library to select k elements from a population:

import random
random.sample(range(low, high), n)

In case of a rather large range of possible numbers, you could use itertools.islice with an infinite random generator:

import itertools
import random

def random_gen(low, high):
    while True:
        yield random.randrange(low, high)

gen = random_gen(1, 100)
items = list(itertools.islice(gen, 10))  # Take first 10 random elements

After the question update it is now clear that you need n distinct (unique) numbers.

import itertools
import random

def random_gen(low, high):
    while True:
        yield random.randrange(low, high)

gen = random_gen(1, 100)

items = set()

# Try to add elem to set until set length is less than 10
for x in itertools.takewhile(lambda x: len(items) < 10, gen):
    items.add(x)

Here's some examples:

decimal a = 1.994444M;

Math.Round(a, 2); //returns 1.99

decimal b = 1.995555M;

Math.Round(b, 2); //returns 2.00

You might also want to look at bankers rounding / round-to-even with the following overload:

Math.Round(a, 2, MidpointRounding.ToEven);

There's more information on it here.

AWS added a new feature to connect to instance without any open port, the AWS SSM Session Manager. https://aws.amazon.com/blogs/aws/new-session-manager/

I've created a neat SSH ProxyCommand script that temporary adds your public ssh key to target instance during connection to target instance. The nice thing about this is you will connect without the need to add the ssh(22) port to your security groups, because the ssh connection is tunneled through ssm session manager.

For resolving a single parameter (I guess what's most commonly needed), this is the simplest I found:

build.buildVariableResolver.resolve("myparameter")

in your Groovy System script build step.

It works very well in Firefox.
Just change the top variable to any other name and try again

        var w = 200;
        var h = 200;
        var left = Number((screen.width/2)-(w/2));
        var tops = Number((screen.height/2)-(h/2));

window.open("templates/sales/index.php?go=new_sale", '', 'toolbar=no, location=no, directories=no, status=no, menubar=no, scrollbars=no, resizable=no, copyhistory=no, width='+w+', height='+h+', top='+tops+', left='+left);

On Windows System, restarting the service "Host Network Service", resolved the issue.

I wrote myself two utility methods that seem to work in most conditions, handling scroll, translation and scaling, but not rotation. I did this after trying to use offsetDescendantRectToMyCoords() in the framework, which had inconsistent accuracy. It worked in some cases but gave wrong results in others.

"point" is a float array with two elements (the x & y coordinates), "ancestor" is a viewgroup somewhere above the "descendant" in the tree hierarchy.

First a method that goes from descendant coordinates to ancestor:

public static void transformToAncestor(float[] point, final View ancestor, final View descendant) {
    final float scrollX = descendant.getScrollX();
    final float scrollY = descendant.getScrollY();
    final float left = descendant.getLeft();
    final float top = descendant.getTop();
    final float px = descendant.getPivotX();
    final float py = descendant.getPivotY();
    final float tx = descendant.getTranslationX();
    final float ty = descendant.getTranslationY();
    final float sx = descendant.getScaleX();
    final float sy = descendant.getScaleY();

    point[0] = left + px + (point[0] - px) * sx + tx - scrollX;
    point[1] = top + py + (point[1] - py) * sy + ty - scrollY;

    ViewParent parent = descendant.getParent();
    if (descendant != ancestor && parent != ancestor && parent instanceof View) {
        transformToAncestor(point, ancestor, (View) parent);
    }
}

Next the inverse, from ancestor to descendant:

public static void transformToDescendant(float[] point, final View ancestor, final View descendant) {
    ViewParent parent = descendant.getParent();
    if (descendant != ancestor && parent != ancestor && parent instanceof View) {
        transformToDescendant(point, ancestor, (View) parent);
    }

    final float scrollX = descendant.getScrollX();
    final float scrollY = descendant.getScrollY();
    final float left = descendant.getLeft();
    final float top = descendant.getTop();
    final float px = descendant.getPivotX();
    final float py = descendant.getPivotY();
    final float tx = descendant.getTranslationX();
    final float ty = descendant.getTranslationY();
    final float sx = descendant.getScaleX();
    final float sy = descendant.getScaleY();

    point[0] = px + (point[0] + scrollX - left - tx - px) / sx;
    point[1] = py + (point[1] + scrollY - top - ty - py) / sy;
}

ViewerJS is helpful to view/embed openoffice format like odt,odp,ods and also pdf.

For embed openoffice/pdf document

<iframe src = "/ViewerJS/#../demo/ohm2013.odp" width='700' height='550' allowfullscreen webkitallowfullscreen></iframe>

/ViewerJS/ is the path of ViewerJS

#../demo/ohm2013 is the path of your file want to embed

For SSMS 18 (specifically 18.6), I found my backup here C:\Windows\SysWOW64\Visual Studio 2017\Backup Files\Solution1.

Kudos to Matthew Lock for giving me the idea to just search across my whole machine!

I suspect that the variable ${file.name} is not substituted correctly. As a result, the value of log4j.appender.FILE.File becomes logs/. As such, Java tries to create a log file named logs/, but probably it is an existing directory, so you get the exception.

As a quick remedy, change the log4j.appender.FILE.File setting to point to file by absolute path, for example /tmp/mytest.log. You should not get an exception.

After that you can proceed to debugging why ${file.name} is not replaced correctly in your runtime environment.

Changing my header to the following solve the problem:

<html>
<head>
<meta http-equiv="X-UA-Compatible" content="IE=Edge" />

I'm not aware of anything that combines this information, but you can use the nvidia-smi tool to get the raw data, like so (thanks to @jmsu for the tip on -l):

use [\\W+] or "[^a-zA-Z0-9]" as regex to match any special characters and also use String.replaceAll(regex, String) to replace the spl charecter with an empty string. remember as the first arg of String.replaceAll is a regex you have to escape it with a backslash to treat em as a literal charcter.

          String c= "hjdg$h&jk8^i0ssh6";
        Pattern pt = Pattern.compile("[^a-zA-Z0-9]");
        Matcher match= pt.matcher(c);
        while(match.find())
        {
            String s= match.group();
        c=c.replaceAll("\\"+s, "");
        }
        System.out.println(c);

You should use ToList() method. (Don't forget about System.Linq namespace)

ex.:

IList<Model> models = Builder<Model>.CreateListOfSize(10).Build();
List<Model> lstMOdels = models.ToList();

In [1]: df
Out[1]:
    Sp  Mt Value  count
0  MM1  S1     a      3
1  MM1  S1     n      2
2  MM1  S3    cb      5
3  MM2  S3    mk      8
4  MM2  S4    bg     10
5  MM2  S4   dgd      1
6  MM4  S2    rd      2
7  MM4  S2    cb      2
8  MM4  S2   uyi      7

In [2]: df.groupby(['Mt'], sort=False)['count'].max()
Out[2]:
Mt
S1     3
S3     8
S4    10
S2     7
Name: count

To get the indices of the original DF you can do:

In [3]: idx = df.groupby(['Mt'])['count'].transform(max) == df['count']

In [4]: df[idx]
Out[4]:
    Sp  Mt Value  count
0  MM1  S1     a      3
3  MM2  S3    mk      8
4  MM2  S4    bg     10
8  MM4  S2   uyi      7

Note that if you have multiple max values per group, all will be returned.

Update

On a hail mary chance that this is what the OP is requesting:

In [5]: df['count_max'] = df.groupby(['Mt'])['count'].transform(max)

In [6]: df
Out[6]:
    Sp  Mt Value  count  count_max

I think the problem may be that you are not finding your element because of the "#" in your call to get it:

window.parent.document.getElementById('#target'); 

You only need the # if you are using jquery. Here it should be:

window.parent.document.getElementById('target'); 

<script>
$(document).ready(function(){
      $('button').attr('class','btn btn-primary');
}); </script>

Try this

#include <stdio.h>

struct context;

struct funcptrs{
  void (*func0)(struct context *ctx);
  void (*func1)(void);
};

struct context{
    struct funcptrs fps;
}; 

void func1 (void) { printf( "1\n" ); }
void func0 (struct context *ctx) { printf( "0\n" ); }

void getContext(struct context *con){
    con->fps.func0 = func0;  
    con->fps.func1 = func1;  
}

int main(int argc, char *argv[]){
 struct context c;
   c.fps.func0 = func0;
   c.fps.func1 = func1;
   getContext(&c);
   c.fps.func0(&c);
   getchar();
   return 0;
}

If you're on Windows you can use Windows Powershell or Powershell 7 with Out-GridView to have a nice list of branches and select with mouse which one you want to delete:

git branch --format "%(refname:short)" --merged  | Out-GridView -PassThru | % { git branch -d $_ }

after clicking OK Powershell will pass this branches names to git branch -d command and delete them

You can use Cursor like that:

USE master
GO

DECLARE @SQL AS VARCHAR(255)
DECLARE @SPID AS SMALLINT
DECLARE @Database AS VARCHAR(500)
SET @Database = 'AdventureWorks2016CTP3'

DECLARE Murderer CURSOR FOR
SELECT spid FROM sys.sysprocesses WHERE DB_NAME(dbid) = @Database

OPEN Murderer

FETCH NEXT FROM Murderer INTO @SPID
WHILE @@FETCH_STATUS = 0

    BEGIN
    SET @SQL = 'Kill ' + CAST(@SPID AS VARCHAR(10)) + ';'
    EXEC (@SQL)
    PRINT  ' Process ' + CAST(@SPID AS VARCHAR(10)) +' has been killed'
    FETCH NEXT FROM Murderer INTO @SPID
    END 

CLOSE Murderer
DEALLOCATE Murderer

I wrote about that in my blog here: http://www.pigeonsql.com/single-post/2016/12/13/Kill-all-connections-on-DB-by-Cursor

Sure! Setup:

>>> import pandas as pd
>>> from random import randint
>>> df = pd.DataFrame({'A': [randint(1, 9) for x in range(10)],
                   'B': [randint(1, 9)*10 for x in range(10)],
                   'C': [randint(1, 9)*100 for x in range(10)]})
>>> df
   A   B    C
0  9  40  300
1  9  70  700
2  5  70  900
3  8  80  900
4  7  50  200
5  9  30  900
6  2  80  700
7  2  80  400
8  5  80  300
9  7  70  800

We can apply column operations and get boolean Series objects:

>>> df["B"] > 50
0    False
1     True
2     True
3     True
4    False
5    False
6     True
7     True
8     True
9     True
Name: B
>>> (df["B"] > 50) & (df["C"] == 900)
0    False
1    False
2     True
3     True
4    False
5    False
6    False
7    False
8    False
9    False

[Update, to switch to new-style .loc]:

And then we can use these to index into the object. For read access, you can chain indices:

>>> df["A"][(df["B"] > 50) & (df["C"] == 900)]
2    5
3    8
Name: A, dtype: int64

but you can get yourself into trouble because of the difference between a view and a copy doing this for write access. You can use .loc instead:

>>> df.loc[(df["B"] > 50) & (df["C"] == 900), "A"]
2    5
3    8
Name: A, dtype: int64
>>> df.loc[(df["B"] > 50) & (df["C"] == 900), "A"].values
array([5, 8], dtype=int64)
>>> df.loc[(df["B"] > 50) & (df["C"] == 900), "A"] *= 1000
>>> df
      A   B    C
0     9  40  300
1     9  70  700
2  5000  70  900
3  8000  80  900
4     7  50  200
5     9  30  900
6     2  80  700
7     2  80  400
8     5  80  300
9     7  70  800

Note that I accidentally typed == 900 and not != 900, or ~(df["C"] == 900), but I'm too lazy to fix it. Exercise for the reader. :^)

Try this ..

    txtview.setCompoundDrawablesWithIntrinsicBounds(
                    R.drawable.image, 0, 0, 0);

Also see this.. http://developer.android.com/reference/android/widget/TextView.html

Try this in xml file

    <TextView
        android:id="@+id/txtStatus"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:drawableLeft="@drawable/image"
        android:drawablePadding="5dp"
        android:maxLines="1"
        android:text="@string/name"/>

And if you do that very often, you could use a ViewSwitcher or a ViewFlipper to ease view substitution.

The easiest is

as @greggo pointed out

string[:-1]

There's lots of subtleties in setting up an efficient and high quality matrix class. Thankfully there's several good implementations floating about.

Think hard about whether you want a fixed size matrix class or a variable sized one. i.e. can you do this:

// These tend to be fast and allocated on the stack.
matrix<3,3> M; 

or do you need to be able to do this

// These are slower but more flexible and partially allocated on the heap 
matrix M(3,3); 

There's good libraries that support either style, and some that support both. They have different allocation patterns and different performances.

If you want to code it yourself, then the template version requires some knowledge of templates (duh). And the dynamic one needs some hacks to get around lots of small allocations if used inside tight loops.

Try =Year(Now()) and format the cell as General.

if you need to call a controller from a view, maybe to load a partial view, you thinking as modular programming, and you should implement HMVC structure in lieu of plane MVC. CodeIgniter didnt implement HMVC natively, but you can use this useful library in order to implement HMVC. https://bitbucket.org/wiredesignz/codeigniter-modular-extensions-hmvc

after setup remember:that all your controllers should extends from MX_Controller in order to using this feature.

When you are using second approach you are initializing arraylist with its predefined values. Like generally we do ArrayList listofStrings = new ArrayList<>(); Let's say you have an array with values, now you want to convert this array into arraylist.

you need to first get the list from the array using Arrays utils. Because the ArrayList is concrete type that implement List interface. It is not guaranteed that method asList, will return this type of implementation.

List<String>  listofOptions = (List<String>) Arrays.asList(options);

then you can user constructoru of an arraylist to instantiate with predefined values.

ArrayList<String> arrlistofOptions = new ArrayList<String>(list);

So your second approach is working that you have passed values which will intantiate arraylist with the list elements.

More over

ArrayList that is returned from Arrays.asList is not an actual arraylist, it is just a wrapper which doesnt allows any modification in the list. If you try to add or remove over Arrays.asList it will give you

This allows you to just get the image data and set to the img src, which is cool.

var oReq = new XMLHttpRequest();
oReq.open("post", '/somelocation/getmypic', true );        
oReq.responseType = "blob";
oReq.onload = function ( oEvent )
{
    var blob = oReq.response;
    var imgSrc = URL.createObjectURL( blob );                        
    var $img = $( '<img/>', {                
        "alt": "test image",
        "src": imgSrc
    } ).appendTo( $( '#bb_theImageContainer' ) );
    window.URL.revokeObjectURL( imgSrc );
};
oReq.send( null );

The basic idea is that the data is returned untampered with, it is placed in a blob and then a url is created to that object in memory. See here and here. Note supported browsers.

git push heroku $(git branch --show-current):master

To sharpen an image we can use the filter (as in many previous answers)

kernel = np.array([[-1, -1, -1],[-1, 8, -1],[-1, -1, 0]], np.float32) 

kernel /= denominator * kernel

It will be the most when the denominator is 1 and will decrease as increased (2.3..)

The most used one is when the denominator is 3.

Below is the implementation.

kernel = np.array([[-1, -1, -1],[-1, 8, -1],[-1, -1, 0]], np.float32) 

kernel = 1/3 * kernel

dst = cv2.filter2D(image, -1, kernel)

Use the URL

https://webcache.googleusercontent.com/search?q=cache:<your url without "http://">

Example:

https://webcache.googleusercontent.com/search?q=cache:stackoverflow.com

It contains a header like this:

This is Google's cache of https://stackoverflow.com/. It is a snapshot of the page as it appeared on 21 Aug 2012 11:33:38 GMT. The current page could have changed in the meantime. Learn more
Tip: To quickly find your search term on this page, press Ctrl+F or ?+F (Mac) and use the find bar.

Similar to the OP's suggested working format & Denison's answer, except using $http.post instead of just $http and is still dependent on jQuery.

The good thing about using jQuery here is that complex objects get passed properly; against manually converting into URL parameters which may garble the data.

$http.post( 'request-url', jQuery.param( { 'message': message } ), {
    headers: { 'Content-Type': 'application/x-www-form-urlencoded' }
});

So there might be a few things wrong here.

First start by reading how to use XMLHttpRequest.open() because there's a third optional parameter for specifying whether to make an asynchronous request, defaulting to true. That means you're making an asynchronous request and need to specify a callback function before you do the send(). Here's an example from MDN:

var oXHR = new XMLHttpRequest();

oXHR.open("GET", "http://www.mozilla.org/", true);

oXHR.onreadystatechange = function (oEvent) {
    if (oXHR.readyState === 4) {
        if (oXHR.status === 200) {
          console.log(oXHR.responseText)
        } else {
           console.log("Error", oXHR.statusText);
        }
    }
};

oXHR.send(null);

Second, since you're getting a 101 error, you might use the wrong URL. So make sure that the URL you're making the request with is correct. Also, make sure that your server is capable of serving your quiz.xml file.

You'll probably have to debug by simplifying/narrowing down where the problem is. So I'd start by making an easy synchronous request so you don't have to worry about the callback function. So here's another example from MDN for making a synchronous request:

var request = new XMLHttpRequest();
request.open('GET', 'file:///home/user/file.json', false); 
request.send(null);

if (request.status == 0)
    console.log(request.responseText);

Also, if you're just starting out with Javascript, you could refer to MDN for Javascript API documentation/examples/tutorials.

Box shadows can use commas to have multiple effects, just like with background images (in CSS3).

Here you go:

$.inArray('specialword', arr)

This function returns a positive integer (the array index of the given value), or -1 if the given value was not found in the array.

Live demo: http://jsfiddle.net/simevidas/5Gdfc/

You probably want to use this like so:

if ( $.inArray('specialword', arr) > -1 ) {
    // the value is in the array
}

For getting a new ordered array, you could take a Map and collect all items with the wanted key in an array and map the wanted ordered keys by taking sifted element of the wanted group.

var itemsArray = [['Anne', 'a'], ['Bob', 'b'], ['Henry', 'b'], ['Andrew', 'd'], ['Jason', 'c'], ['Thomas', 'b']],_x000D_
    sortingArr = [ 'b', 'c', 'b', 'b', 'a', 'd' ],_x000D_
    map = itemsArray.reduce((m, a) => m.set(a[1], (m.get(a[1]) || []).concat([a])), new Map),_x000D_
    result = sortingArr.map(k => (map.get(k) || []).shift());_x000D_
_x000D_
console.log(result);

The shortest way:

python3 -m pip install package
python -m pip install package

When you read() the file, you may get a newline character '\n' in your string. Try either

if UserInput.strip() == 'List contents': 

or

if 'List contents' in UserInput: 

Also note that your second file open could also use with:

with open('/Users/.../USER_INPUT.txt', 'w+') as UserInputFile:     if UserInput.strip() == 'List contents': # or if s in f:         UserInputFile.write("ls")     else:         print "Didn't work" 

If you have an uncommitted change (its only in your working copy) that you wish to revert to the copy in your latest commit, do the following:

git checkout filename

You could also write your own IFormatProvider, though I suppose eventually you'd have to think of a way to do the actual truncation.

The .NET Framework also supports custom formatting. This typically involves the creation of a formatting class that implements both IFormatProvider and ICustomFormatter. (msdn)

At least it would be easily reusable.

There is an article about how to implement your own IFormatProvider/ICustomFormatter here at CodeProject. In this case, "extending" an existing numeric format might be the best bet. It doesn't look too hard.

You have to modify the php.ini files in your xampp folder. Three files in three different places need to be changed.

Follow the following steps to enable curl library with XAMPP in Windows:

Step 1:

Browse and open the following 3 files

C:\Program Files\xampp\apache\bin\php.ini
C:\Program Files\xampp\php\php.ini
C:\Program Files\xampp\php\php4\php.ini

Step 2:

Uncomment the following line in your php.ini file by removing the semicolon (;).

;extension=php_curl.dll

After that it will look something like something below-

extension=php_curl.dll

Step 3:

Restart your Apache server.

Step 4:

Check your phpinfo() to see whether curl has properly enabled or not.

Enjoy using curl() library.

When developing an application that uses https, your test server doesn't have a valid SSL certificate. Or sometimes the web site is using a self-signed certificate or the web site is using free SSL certificate. So if you try to connect to the server using Apache HttpClient, you will get a exception telling that the "peer not authenticated". Though it is not a good practice to trust all the certificates in a production software, you may have to do so according to the situation. This solution resolves the exception caused by "peer not authenticated".

But before we go to the solution, I must warn you that this is not a good idea for a production application. This will violate the purpose of using a security certificate. So unless you have a good reason or if you are sure that this will not cause any problem, don't use this solution.

Normally you create a HttpClient like this.

HttpClient httpclient = new DefaultHttpClient();

But you have to change the way you create the HttpClient.

First you have to create a class extending org.apache.http.conn.ssl.SSLSocketFactory.

import org.apache.http.conn.ssl.SSLSocketFactory;
import java.io.IOException;
import java.net.Socket;
import java.net.UnknownHostException;
import java.security.KeyManagementException;
import java.security.KeyStore;
import java.security.KeyStoreException;
import java.security.NoSuchAlgorithmException;
import java.security.UnrecoverableKeyException;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;

import javax.net.ssl.SSLContext;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;

public class MySSLSocketFactory extends SSLSocketFactory {
         SSLContext sslContext = SSLContext.getInstance("TLS");

    public MySSLSocketFactory(KeyStore truststore) throws NoSuchAlgorithmException, KeyManagementException, KeyStoreException, UnrecoverableKeyException {
        super(truststore);

        TrustManager tm = new X509TrustManager() {
            public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {
            }

            public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {
            }

            public X509Certificate[] getAcceptedIssuers() {
                return null;
            }
        };

        sslContext.init(null, new TrustManager[] { tm }, null);
    }

    @Override
    public Socket createSocket(Socket socket, String host, int port, boolean autoClose) throws IOException, UnknownHostException {
        return sslContext.getSocketFactory().createSocket(socket, host, port, autoClose);
    }

    @Override
    public Socket createSocket() throws IOException {
        return sslContext.getSocketFactory().createSocket();
    }
}

Then create a method like this.

public HttpClient getNewHttpClient() {
     try {
         KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());
         trustStore.load(null, null);

         SSLSocketFactory sf = new MySSLSocketFactory(trustStore);
         sf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);

         HttpParams params = new BasicHttpParams();
         HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
         HttpProtocolParams.setContentCharset(params, HTTP.UTF_8);

         SchemeRegistry registry = new SchemeRegistry();
         registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
         registry.register(new Scheme("https", sf, 443));

         ClientConnectionManager ccm = new ThreadSafeClientConnManager(params, registry);

         return new DefaultHttpClient(ccm, params);
     } catch (Exception e) {
         return new DefaultHttpClient();
     }
}

Then you can create the HttpClient.

HttpClient httpclient = getNewHttpClient();

If you are trying to send a post request to a login page the rest of the code would be like this.

private URI url = new URI("url of the action of the form");
HttpPost httppost =  new HttpPost(url);
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();  
nameValuePairs.add(new BasicNameValuePair("username", "user"));  
nameValuePairs.add(new BasicNameValuePair("password", "password"));
try {
    httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
    HttpResponse response = httpclient.execute(httppost);
    HttpEntity entity = response.getEntity();
    InputStream is = entity.getContent();
} catch (UnsupportedEncodingException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
} catch (ClientProtocolException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
} catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

You get the html page to the InputStream. Then you can do whatever you want with the returned html page.

But here you will face a problem. If you want to manage a session using cookies, you will not be able to do it with this method. If you want to get the cookies, you will have to do it via a browser. Then only you will receive cookies.

The code formatting is available in Visual Studio Code through the following shortcuts:

• On Windows Shift + Alt + F
• On Mac Shift + Option + F
• On Linux Ctrl + Shift + I

Alternatively, you can find the shortcut, as well as other shortcuts, through the 'Command Palette' provided in the editor with Ctrl +Shift+ P (or Command + Shift + P on Mac), and then searching for format document.

For unsaved snippets

1. Open command palette (Win: F1 or Ctrt+Shift+P)

2. Find 'Change Language Model'

3. Select language e.g. json. By now syntax should be highlighted.

4. Format document (e.g. Open Command Palette -> 'Format Document')

Unformat

1. Select text
2. Command Palette -> Join Lines

Tkinter supports a mechanism called protocol handlers. Here, the term protocol refers to the interaction between the application and the window manager. The most commonly used protocol is called WM_DELETE_WINDOW, and is used to define what happens when the user explicitly closes a window using the window manager.

You can use the protocol method to install a handler for this protocol (the widget must be a Tk or Toplevel widget):

Here you have a concrete example:

import tkinter as tk
from tkinter import messagebox

root = tk.Tk()

def on_closing():
    if messagebox.askokcancel("Quit", "Do you want to quit?"):
        root.destroy()

root.protocol("WM_DELETE_WINDOW", on_closing)
root.mainloop()

You override $today in the if statement.

if($dd<10){$dd='0'+dd} if($mm<10){$mm='0'+$mm} $today = $dd+'/'+$mm+'/'+$yyyy;

It is then not a Date() object anymore - hence the error.
