In Erlang there is no need to differentiate between aggregates, once the aggregate is composed by data structures inside the state, instead of OO composition. See an example: https://github.com/bryanhunter/cqrs-with-erlang/tree/ndc-london

You have to set seed every time you want to get a reproducible random result.

set.seed(1)
rnorm(4)
set.seed(1)
rnorm(4)

Your JFrame default close action can be set to "DISPOSE_ON_CLOSE" instead of EXIT_ON_CLOSE (why people keep using EXIT_ON_CLOSE is beyond me).

If you have any undisposed windows or non-daemon threads, your application will not terminate. This should be considered a error (and solving it with System.exit is a very bad idea).

The most common culprits are java.util.Timer and a custom Thread you've created. Both should be set to daemon or must be explicitly killed.

If you want to check for all active frames, you can use Frame.getFrames(). If all Windows/Frames are disposed of, then use a debugger to check for any non-daemon threads that are still running.

select * 
from tempdb.INFORMATION_SCHEMA.COLUMNS
where table_name like '#MyTempTable%'

function valid(id)
    {
        var textVal=document.getElementById(id).value;
        if (!textVal.match("Tryit") 
        {
            alert("Field says Tryit");
            return false;
        } 
        else 
        {
            return true;
        }
     }

Use this for expressing things

You can write more general logic to allow user to enter only specific number of times, as the same use-case arises in many real-world applications.

def getValidInt(iMaxAttemps = None):
  iCount = 0
  while True:
    # exit when maximum attempt limit has expired
    if iCount != None and iCount > iMaxAttemps:
       return 0     # return as default value

    i = raw_input("Enter no")
    try:
       i = int(i)
    except ValueError as e:
       print "Enter valid int value"
    else:
       break

    return i

age = getValidInt()
# do whatever you want to do.

You will certainly be able to do that using WITH clause, or use analytic functions available in Oracle SQL.

With some effort you'd be able to get anything out of them in terms of cycles as in ordinary procedural languages. Both approaches are pretty powerful compared to ordinary SQL.

http://www.dba-oracle.com/t_with_clause.htm

http://www.orafaq.com/node/55

It requires some effort though. Don't be afraid to post a concrete example.

Using simple pseudo table DUAL helps too.

Either Collections.emptyMap(), or if type inference doesn't work in your case,
Collections.<String, String>emptyMap()

This way:

$email = Mage::getSingleton('customer/session')->getCustomer()->getEmail();
echo $email;

I didn't have to change my prostgresql.conf file but, i did have to do the following based on my psql via command line was connecting and pgAdmin not connecting on RDS with AWS.

I did have my RDS set to Publicly Accessible. I made sure my ACL and security groups were wide open and still problem so, I did the following: sudo find . -name *.conf then sudo nano ./data/pg_hba.conf then added to top of directives in pg_hba.conf file host all all 0.0.0.0/0 md5 and pgAdmin automatically logged me in.

This also worked in pg_hba.conf file host all all md5 without any IP address and this also worked with my IP address host all all <myip>/32 md5

As a side note, my RDS was in my default VPC. I had an identical RDS instance in my non-default VPC with identical security group, ACL and security group settings to my default VPC and I could not get it to work. Not sure why but, that's for another day.

It works if id value and name value are different:

<input type="password" class="form-control"name="password" id="mainpassword">
password: {     required: true,     } , 
cpassword: {required: true, equalTo: '#mainpassword' },

In the above answers, it is important to understand what is meant by "values are expanded at declaration/use time". Giving a value like *.c does not entail any expansion. It is only when this string is used by a command that it will maybe trigger some globbing. Similarly, a value like $(wildcard *.c) or $(shell ls *.c) does not entail any expansion and is completely evaluated at definition time even if we used := in the variable definition.

Try the following Makefile in directory where you have some C files:

VAR1 = *.c
VAR2 := *.c
VAR3 = $(wildcard *.c)
VAR4 := $(wildcard *.c)
VAR5 = $(shell ls *.c)
VAR6 := $(shell ls *.c)

all :
    touch foo.c
    @echo "now VAR1 = \"$(VAR1)\"" ; ls $(VAR1)
    @echo "now VAR2 = \"$(VAR2)\"" ; ls $(VAR2)
    @echo "now VAR3 = \"$(VAR3)\"" ; ls $(VAR3)
    @echo "now VAR4 = \"$(VAR4)\"" ; ls $(VAR4)
    @echo "now VAR5 = \"$(VAR5)\"" ; ls $(VAR5)
    @echo "now VAR6 = \"$(VAR6)\"" ; ls $(VAR6)
    rm -v foo.c

Running make will trigger a rule that creates an extra (empty) C file, called foo.c but none of the 6 variables has foo.c in its value.

Run apt-get install gcc in Suse Linux

You should be able to use join, which joins on the index as default. Given your desired result, you must use outer as the join type.

>>> df1.join(df2, how='outer')
            V1  V2
A 1/1/2012  12  15
  2/1/2012  14 NaN
  3/1/2012 NaN  21
B 1/1/2012  15  24
  2/1/2012   8   9
C 1/1/2012  17 NaN
  2/1/2012   9 NaN
D 1/1/2012 NaN   7
  2/1/2012 NaN  16

Signature: _.join(other, on=None, how='left', lsuffix='', rsuffix='', sort=False) Docstring: Join columns with other DataFrame either on index or on a key column. Efficiently Join multiple DataFrame objects by index at once by passing a list.

Without loop:

document.getElementsByName('gender').reduce(function(value, checkable) {
    if(checkable.checked == true) 
        value = checkable.value; 
    return value;
}, '');

reduce is just a function that will feed sequentially array elements to second argument of callback, and previously returned function to value, while for the first run, it will use value of second argument.

The only minus of this approach is that reduce will traverse every element returned by getElementsByName even after it have found selected radio button.

If you need cryptographically-secure random numbers (e.g. for encryption), and you're in a browser, you can use the DOM cryptography API:

int random() {
  final ary = new Int32Array(1);
  window.crypto.getRandomValues(ary);
  return ary[0];
}

This works in Dartium, Chrome, and Firefox, but likely not in other browsers as this is an experimental API.

Below works for me:

<TextView
    android:id="@+id/tv_username"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Sarah" />

<TextView
    android:id="@+id/tv_distance"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignBottom="@+id/tv_username"
    android:layout_alignParentEnd="true"
    android:layout_toEndOf="@+id/tv_username"
    android:text="San Marco"
    android:textAlignment="viewEnd" />

Please note the android:layout_alignParentEnd and android:textAlignment settings of the second TextView.

I had almost the same as Jesper, only I reused the webclient and disposed it correctly. Also I cleaned up some responses by removing the extra \n at the end.

    private static IPAddress GetExternalIp () {
      using (WebClient client = new WebClient()) {
        List<String> hosts = new List<String>();
        hosts.Add("https://icanhazip.com");
        hosts.Add("https://api.ipify.org");
        hosts.Add("https://ipinfo.io/ip");
        hosts.Add("https://wtfismyip.com/text");
        hosts.Add("https://checkip.amazonaws.com/");
        hosts.Add("https://bot.whatismyipaddress.com/");
        hosts.Add("https://ipecho.net/plain");
        foreach (String host in hosts) {
          try {
            String ipAdressString = client.DownloadString(host);
            ipAdressString = ipAdressString.Replace("\n", "");
            return IPAddress.Parse(ipAdressString);
          } catch {
          }
        }
      }
      return null;
    }

if you change UseSubmitBehavior="True" to UseSubmitBehavior="False" your problem will be solved

<asp:Button ID="BtnDis" runat="server" CommandName="BtnDis" CommandArgument='<%#Eval("Id")%>' Text="Discription" CausesValidation="True" UseSubmitBehavior="False" />

I think Internal and External Linkage in C++ gives a clear and concise explanation:

A translation unit refers to an implementation (.c/.cpp) file and all header (.h/.hpp) files it includes. If an object or function inside such a translation unit has internal linkage, then that specific symbol is only visible to the linker within that translation unit. If an object or function has external linkage, the linker can also see it when processing other translation units. The static keyword, when used in the global namespace, forces a symbol to have internal linkage. The extern keyword results in a symbol having external linkage.

The compiler defaults the linkage of symbols such that:

Non-const global variables have external linkage by default
Const global variables have internal linkage by default
Functions have external linkage by default

you probably want to use a separate value that tracks if the input is valid:

good_input = None
while not good_input:
     user_input = raw_input("enter the right letter : ")
     if user_input in list_of_good_values: 
        good_input = user_input

Came up with this solution:

function scrollToTop() {
let currentOffset = window.pageYOffset;
const arr = [];

for (let i = 100; i >= 0; i--) {
    arr.push(new Promise(res => {
            setTimeout(() => {
                    res(currentOffset * (i / 100));
                },
                2 * (100 - i))
        })
    );
}

arr.reduce((acc, curr, index, arr) => {
    return acc.then((res) => {
        if (typeof res === 'number')
            window.scrollTo(0, res)
        return curr
    })
}, Promise.resolve(currentOffset)).then(() => {
    window.scrollTo(0, 0)
})}

simplest this to do is find what other service is using the same service id as mysql does in windows.

When i looked through the list of services running on my pc (even after a restart...i still had the problem)

I quickly realised i had webmatrix installed on my computer previous to wamp server...webmatrix installed its own copy of mysql and set it to automatically startup another instance each time i logged in.

As soon as the other instance of mysql associated with web matrix was stopped (and changed from automatic startup to manual) my problem with WAMP mysql was solved.

I believe when you import the file you can select the Column Type. Make it Text instead of Number. I don't have a copy in front of me at the moment to check though.

JAVA_HOME is not the name of the java executable. But of the directory, java was installed in. The executable should be $JAVA_HOME/bin/java.

The which command is not helpful for you there. It will not give you the java home, but most likely this is just a wrapper or symlink to java installed in a very different directory.

Coarse-grained and Fine-grained both think about optimizing a number of servicess. But the difference is in the level. I like to explain with an example, you will understand easily.

Fine-grained: For example, I have 100 services like findbyId, findbyCategry, findbyName...... so on. Instead of that many services why we can not provide find(id, category, name....so on). So this way we can reduce the services. This is just an example, but the goal is how to optimize the number of services.

Coarse-grained: For example, I have 100 clients, each client have their own set of 100 services. So I have to provide 100*100 total services. It is very much difficult. Instead of that what I do is, I identify all common services which apply to most of the clients as one service set and remaining separately. For example in 100 services 50 services are common. So I have to manage 100*50 + 50 only.

A blanket "no you shouldn't" is terrible advice. This is perfectly reasonable in many situations depending on your use case, workload, data entropy, hardware, etc.. What you shouldn't do is make assumptions.

It should be noted that you can specify a prefix which will limit MySQL's indexing, thereby giving you some help in narrowing down the results before scanning the rest. This may, however, become less useful over time as your prefix "fills up" and becomes less unique.

It's very simple to do, e.g.:

CREATE TABLE IF NOT EXISTS `foo` (
  `id` varchar(128),
  PRIMARY KEY (`id`(4))
)

Also note that the prefix (4) appears after the column quotes. Where the 4 means that it should use the first 4 characters of the 128 possible characters that can exist as the id.

Lastly, you should read how index prefixes work and their limitations before using them: https://dev.mysql.com/doc/refman/8.0/en/create-index.html

As opposed to find() which can return 1 or more documents, findById() can only return 0 or 1 document. Document(s) can be thought of as record(s).

I dont think youre returning json object from server. just a string.

you need the dataType of the return object to be json

Below is the perfect one for mentioned requirement :

^[0-9]{1,3}(,[0-9]{3})*(([\\.,]{1}[0-9]*)|())$

Also, if you want to send embedded spaces with the input command, use %s

adb shell input text 'this%sis%san%sexample'   

will yield

this is an example

being input.

% itself does not need escaping - only the special %s pair is treated specially. This leads of course to the obvious question of how to enter the literal string %s, which you would have to do with two separate commands.

Sometimes we know in advance that the value stored in a given integer variable will always be positive-when it is being used to only count things, for example. In such a case we can declare the variable to be unsigned, as in, unsigned int num student;. With such a declaration, the range of permissible integer values (for a 32-bit compiler) will shift from the range -2147483648 to +2147483647 to range 0 to 4294967295. Thus, declaring an integer as unsigned almost doubles the size of the largest possible value that it can otherwise hold.

To sum with decimal use this:

In the javascript change parseInt with parseFloat and add this line tot.toFixed(2); for this result:

    function findTotal(){
    var arr = document.getElementsByName('qty');
    var tot=0;
    for(var i=0;i<arr.length;i++){
        if(parseFloat(arr[i].value))
            tot += parseFloat(arr[i].value);
    }
    document.getElementById('total').value = tot;
    tot.toFixed(2);
}

Use step=".01" min="0" type="number" in the input filed

Qty1 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty1"/><br>
Qty2 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty2"/><br>
Qty3 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty3"/><br>
Qty4 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty4"/><br>
Qty5 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty5"/><br>
Qty6 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty6"/><br>
Qty7 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty7"/><br>
Qty8 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty8"/><br>
<br><br>
Total : <input type="number" step=".01" min="0" name="total" id="total"/>

To get all the records where record created date is today's date Use the code after WHERE clause

WHERE  CAST(Submission_date AS DATE) = CAST( curdate() AS DATE)

The simplest way to extract a number from a string is to use regular expressions and findall.

>>> import re
>>> s = '300 gm'
>>> re.findall('\d+', s)
['300']
>>> s = '300 gm 200 kgm some more stuff a number: 439843'
>>> re.findall('\d+', s)
['300', '200', '439843']

It might be that you need something more complex, but this is a good first step.

Note that you'll still have to call int on the result to get a proper numeric type (rather than another string):

>>> map(int, re.findall('\d+', s))
[300, 200, 439843]

List<string> myCollection = new List<string>()
{
    "Bob", "Bob","Alex", "Abdi", "Abdi", "Bob", "Alex", "Bob","Abdi"
};

myCollection.Sort();
foreach (var name in myCollection.Distinct())
{
    Console.WriteLine(name + " " + myCollection.Count(x=> x == name));
}

output: Abdi 3 Alex 2 Bob 4

there is the class I mentioned in the comment we had with Sean Patrick Floyd : I did it with a peculiar use which needs WeakReference, but you can change it by any object with ease.

the second argument in ROUNDUP, eg =ROUNDUP(12345.6789,3) refers to the negative of the base-10 column with that power of 10, that you want rounded up. eg 1000 = 10^3, so to round up to the next highest 1000, use ,-3)

=ROUNDUP(12345.6789,-4) = 20,000
=ROUNDUP(12345.6789,-3) = 13,000
=ROUNDUP(12345.6789,-2) = 12,400
=ROUNDUP(12345.6789,-1) = 12,350
=ROUNDUP(12345.6789,0) = 12,346
=ROUNDUP(12345.6789,1) = 12,345.7
=ROUNDUP(12345.6789,2) = 12,345.68
=ROUNDUP(12345.6789,3) = 12,345.679

So, to answer your question: if your value is in A1, use =ROUNDUP(A1,-1)

for run in {1..10}; do
  command
done

Or as a one-liner for those that want to copy and paste easily:

for run in {1..10}; do command; done

If your ranage has variable use this syntax ref

count=10
for i in $(seq $count); do
    command
done

If using Windows/MFC, and need the string for more than immediate output try:

int i = 4;
CString strOutput;
strOutput.Format("Player %d", i);

In my case, the error was caused by incorrect mapping settings in the file applicationhost.config (\System32\inetsrv\config). For some reason, Visual Studio 2013 corrupted it while creating a virtual directory in IIS. The fix was to manually edit the sites section in the file.

For fetching the name of all tables:

SELECT table_name 
FROM information_schema.tables;

If you need to fetch it for a specific database:

SELECT table_name 
FROM information_schema.tables
WHERE table_schema = 'your_db_name';

Output:

+--------------------+
| table_name         |
+--------------------+
| myapp              |
| demodb             |

    document.getElementById("something").innerHTML = "<img src=\"something\" onmouseover=\"change('ex1')\" />";

OR

It should be working...

I want to share this code I wrote for the issue I had to resolve. It was tested in most of the major browsers and works like a charm, for me!

It may seems that this code is very similar to the other answers but it modifyed so that I can use it insted of the browser object in jquery which missed for me recently, of course it is a combination from the above codes, with little improvements from my part I made:

(function($, ua){

var M = ua.match(/(opera|chrome|safari|firefox|msie|trident(?=\/))\/?\s*(\d+)/i) || [],
    tem, 
    res;

if(/trident/i.test(M[1])){
    tem = /\brv[ :]+(\d+)/g.exec(ua) || [];
    res = 'IE ' + (tem[1] || '');
}
else if(M[1] === 'Chrome'){
    tem = ua.match(/\b(OPR|Edge)\/(\d+)/);
    if(tem != null)

You can use tf.convert_to_tensor():

import tensorflow as tf
import numpy as np

data = [[1,2,3],[4,5,6]]
data_np = np.asarray(data, np.float32)

data_tf = tf.convert_to_tensor(data_np, np.float32)

sess = tf.InteractiveSession()  
print(data_tf.eval())

sess.close()

Here's a link to the documentation for this method:

https://www.tensorflow.org/api_docs/python/tf/convert_to_tensor

Close and re-open the tab. That should do the trick.

Typical implementation:

import subprocess

p = subprocess.Popen('ls', shell=True, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
for line in p.stdout.readlines():
    print line,
retval = p.wait()

You are free to do what you want with the stdout data in the pipe. In fact, you can simply omit those parameters (stdout= and stderr=) and it'll behave like os.system().

You can also use sequence unpacking with zip:

L = [(1,2),(2,3),(4,5),(3,4),(6,7),(6,7),(3,8)]

_, res = zip(*L)

print(res)

# (2, 3, 5, 4, 7, 7, 8)

This also creates a tuple _ from the discarded first elements. Extracting only the second is possible, but more verbose:

from itertools import islice

res = next(islice(zip(*L), 1, None))

For military time formatting,

select TO_CHAR(SYSDATE, 'yyyy-mm-dd hh24:mm:ss') from DUAL

--2018-07-10 15:07:15

If you want your date to round DOWN to Month, Day, Hour, Minute, you can try

SELECT TO_CHAR( SYSDATE, 'yyyy-mm-dd hh24:mi:ss') "full-date" --2018-07-11 10:40:26
, TO_CHAR( TRUNC(SYSDATE, 'year'), 'yyyy-mm-dd hh24:mi:ss') "trunc-to-year"-- 2018-01-01 00:00:00
, TO_CHAR( TRUNC(SYSDATE, 'month'), 'yyyy-mm-dd hh24:mi:ss') "trunc-to-month" -- 2018-07-01 00:00:00
, TO_CHAR( TRUNC(SYSDATE, 'day'), 'yyyy-mm-dd hh24:mi:ss') "trunc-to-Sunday" -- 2018-07-08 00:00:00
, TO_CHAR( TRUNC(SYSDATE, 'dd'), 'yyyy-mm-dd hh24:mi:ss') "trunc-to-day" -- 2018-07-11 00:00:00
, TO_CHAR( TRUNC(SYSDATE, 'hh'), 'yyyy-mm-dd hh24:mi:ss') "trunc-to-hour" -- 2018-07-11 10:00:00
, TO_CHAR( TRUNC(SYSDATE, 'mi'), 'yyyy-mm-dd hh24:mi:ss') "trunc-to-minute" -- 2018-07-11 10:40:00
from DUAL

First download the JavaMail API and make sure the relevant jar files are in your classpath.

Here's a full working example using GMail.

import java.util.*;
import javax.mail.*;
import javax.mail.internet.*;

public class Main {

    private static String USER_NAME = "*****";  // GMail user name (just the part before "@gmail.com")
    private static String PASSWORD = "********"; // GMail password
    private static String RECIPIENT = "[email protected]";

    public static void main(String[] args) {
        String from = USER_NAME;
        String pass = PASSWORD;
        String[] to = { RECIPIENT }; // list of recipient email addresses
        String subject = "Java send mail example";
        String body = "Welcome to JavaMail!";

        sendFromGMail(from, pass, to, subject, body);
    }

    private static void sendFromGMail(String from, String pass, String[] to, String subject, String body) {
        Properties props = System.getProperties();
        String host = "smtp.gmail.com";
        props.put("mail.smtp.starttls.enable", "true");
        props.put("mail.smtp.host", host);
        props.put("mail.smtp.user", from);
        props.put("mail.smtp.password", pass);
        props.put("mail.smtp.port", "587");
        props.put("mail.smtp.auth", "true");

        Session session = Session.getDefaultInstance(props);
        MimeMessage message = new MimeMessage(session);

        try {
            message.setFrom(new InternetAddress(from));
            InternetAddress[] toAddress = new InternetAddress[to.length];

            // To get the array of addresses
            for( int i = 0; i < to.length; i++ ) {
                toAddress[i] = new InternetAddress(to[i]);
            }

            for( int i = 0; i < toAddress.length; i++) {
                message.addRecipient(Message.RecipientType.TO, toAddress[i]);
            }

            message.setSubject(subject);
            message.setText(body);
            Transport transport = session.getTransport("smtp");
            transport.connect(host, from, pass);
            transport.sendMessage(message, message.getAllRecipients());
            transport.close();
        }
        catch (AddressException ae) {
            ae.printStackTrace();
        }
        catch (MessagingException me) {
            me.printStackTrace();
        }
    }
}

Naturally, you'll want to do more in the catch blocks than print the stack trace as I did in the example code above. (Remove the catch blocks to see which method calls from the JavaMail API throw exceptions so you can better see how to properly handle them.)

Thanks to @jodonnel and everyone else who answered. I'm giving him a bounty because his answer led me about 95% of the way to a complete answer.

I think I see your problem, you need to use the @ syntax to define parameters you will pass in this way, also I'm not sure what loginID or password are doing you don't seem to define them anywhere and they are not being used as URL parameters so are they being sent as query parameters?

This is what I can suggest based on what I see so far:

.factory('MagComments', function ($resource) {
    return $resource('http://localhost/dooleystand/ci/api/magCommenct/:id', {
      loginID : organEntity,
      password : organCommpassword,
      id : '@magId'
    });
  })

The @magId string will tell the resource to replace :id with the property magId on the object you pass it as parameters.

I'd suggest reading over the documentation here (I know it's a bit opaque) very carefully and looking at the examples towards the end, this should help a lot.

For python2.x:

sudo pip install BeautifulSoup4

For python3:

sudo apt-get install python3-bs4

The answer may be that you have not initialized the database yet. After installing postgres, but before initializing the database, the postgres*.sql files will be absent. After initializing the database the postgres*.sql files will appear. (Centos 6, Postgres 9.3 demonstrated here)

[root@localhost /]# yum -y install postgresql93 postgresql93-server 
[root@localhost /]# ls /var/lib/pgsql/9.3/data/
[root@localhost /]#
[root@localhost /]# service postgresql-9.3 initdb
Initializing database:                                     [  OK  ]

I think System.Math.Truncate is what you're looking for.

Use properties file. Here is a good start: http://www.mkyong.com/java/java-properties-file-examples/

On Fedora I do locate ~/.ssh which tells me keys are at

/root/.ssh
/root/.ssh/authorized_keys

It takes two numbers from the user, feeds them to the function called add (in the very last line of the code), and add will sum them up and print them.

#!/bin/bash

read -p "Enter the first  value: " x
read -p "Enter the second value: " y

add(){
    arg1=$1 # arg1 gets to be the first  assigned argument (note there are no spaces)
      arg2=$2 # arg2 gets to be the second assigned argument (note there are no spaces)

    echo $(($arg1 + $arg2))
}

add x y # Feeding the arguments

If you're running a jar file with java -jar, the -classpath argument is ignored. You need to set the classpath in the manifest file of your jar, like so:

Class-Path: jar1-name jar2-name directory-name/jar3-name

See the Java tutorials: Adding Classes to the JAR File's Classpath.

Edit: I see you already tried setting the class path in the manifest, but are you sure you used the correct syntax? If you skip the ':' after "Class-Path" like you showed, it would not work.

Try:

function LoadData (callback)
{
    // ... Process whatever data
    callback (loadedData, currentObject);
}

Functions are first class in JavaScript; you can just pass them around.

I have tried everything - but nothing helped. After searching for several hours I found this information:

Apache 2.4.18 for some reason does not load php 7.2 curl. I updated my Apache to 2.4.29 and curl loaded instantly

http://forum.wampserver.com/read.php?2,149346,149348

What should I say: I updated Apache and curl was running like charm

I need to add that, if the Module name and the sub name is the same you have such issue. Consider change the Module name to mod_Test instead of "Test" which is the same as the sub.

Over a year later... if what you need is get the auto generated id of a table, you can just

SELECT @ReportOptionId = SCOPE_IDENTITY()

Otherwise, it seems like you are stuck with using a table.

You need to add 2 methods, note __hash__ and __eq__:

class MyThing:
    def __init__(self,name,location,length):
        self.name = name
        self.location = location
        self.length = length

    def __hash__(self):
        return hash((self.name, self.location))

    def __eq__(self, other):
        return (self.name, self.location) == (other.name, other.location)

    def __ne__(self, other):
        # Not strictly necessary, but to avoid having both x==y and x!=y
        # True at the same time
        return not(self == other)

The Python dict documentation defines these requirements on key objects, i.e. they must be hashable.

Start with:

setup.exe /?

And you should see a dialog popup with some options displayed.

Suggest you not to use Count because count always makes extra loads for db use SELECT 1 and it returns 1 if your record right there otherwise it returns null and you can handle it.

The (m) indicates the column display width; applications such as the MySQL client make use of this when showing the query results.

For example:

| v   | a   |  b  |   c |
+-----+-----+-----+-----+
| 1   | 1   |  1  |   1 |
| 10  | 10  | 10  |  10 |
| 100 | 100 | 100 | 100 |

Here a, b and c are using TINYINT(1), TINYINT(2) and TINYINT(3) respectively. As you can see, it pads the values on the left side using the display width.

It's important to note that it does not affect the accepted range of values for that particular type, i.e. TINYINT(1) still accepts [-128 .. 127].

I am not sure why but the command below worked for me.

pip install pyqt5

Of course I updated Anaconda and Navigator before running this command.

It is possible to override only write method of sys.stdout with one that calls flush. Suggested method implementation is below.

def write_flush(args, w=stdout.write):
    w(args)
    stdout.flush()

Default value of w argument will keep original write method reference. After write_flush is defined, the original write might be overridden.

stdout.write = write_flush

The code assumes that stdout is imported this way from sys import stdout.

The answer provided by Zin Min solved my problem with a single line of code. Excellent!

I was having the same issue of converting a generic List to a generic ObservableCollection to use the values from my List to populate a ComboBox that is participating in binding via a factory class for a WPF Window.

_expediteStatuses = new ObservableCollection<ExpediteStatus>(_db.getExpediteStatuses());

Here is the signature for the getExpediteStatuses method:

public List<ExpediteStatus> getExpediteStatuses()

What this means is that you are trying to print out/output a value which is at least partially uninitialized. Can you narrow it down so that you know exactly what value that is? After that, trace through your code to see where it is being initialized. Chances are, you will see that it is not being fully initialized.

If you need more help, posting the relevant sections of source code might allow someone to offer more guidance.

EDIT

I see you've found the problem. Note that valgrind watches for Conditional jump or move based on unitialized variables. What that means is that it will only give out a warning if the execution of the program is altered due to the uninitialized value (ie. the program takes a different branch in an if statement, for example). Since the actual arithmetic did not involve a conditional jump or move, valgrind did not warn you of that. Instead, it propagated the "uninitialized" status to the result of the statement that used it.

It may seem counterintuitive that it does not warn you immediately, but as mark4o pointed out, it does this because uninitialized values get used in C all the time (examples: padding in structures, the realloc() call, etc.) so those warnings would not be very useful due to the false positive frequency.

Just add -o nonempty in command line, like this:

s3fs -o nonempty  <bucket-name> </mount/point/>

Try this:

var d = new Date(),
    minutes = d.getMinutes().toString().length == 1 ? '0'+d.getMinutes() : d.getMinutes(),
    hours = d.getHours().toString().length == 1 ? '0'+d.getHours() : d.getHours(),
    ampm = d.getHours() >= 12 ? 'pm' : 'am',
    months = ['Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sep','Oct','Nov','Dec'],
    days = ['Sun','Mon','Tue','Wed','Thu','Fri','Sat'];
return days[d.getDay()]+' '+months[d.getMonth()]+' '+d.getDate()+' '+d.getFullYear()+' '+hours+':'+minutes+ampm;

Or, in order to avoid modifying slowFunc (say you don't have access to the source code for instance):

var source = new CancellationTokenSource(); //original code
source.Token.Register(CancelNotification); //original code
source.CancelAfter(TimeSpan.FromSeconds(1)); //original code
var completionSource = new TaskCompletionSource<object>(); //New code
source.Token.Register(() => completionSource.TrySetCanceled()); //New code
var task = Task<int>.Factory.StartNew(() => slowFunc(1, 2), source.Token); //original code

//original code: await task;  
await Task.WhenAny(task, completionSource.Task); //New code

You can also use nice extension methods from https://github.com/StephenCleary/AsyncEx and have it looks as simple as:

await Task.WhenAny(task, source.Token.AsTask());

I use Xerces:

In VS2010 if you load an XML file into the editor, click the XML menu >> Create Schema.

Fastest on my tests:

conn.row_factory = lambda c, r: dict(zip([col[0] for col in c.description], r))
c = conn.cursor()

%timeit c.execute('SELECT * FROM table').fetchall()
19.8 µs ± 1.05 µs per loop (mean ± std. dev. of 7 runs, 100000 loops each)

vs:

conn.row_factory = lambda c, r: dict([(col[0], r[idx]) for idx, col in enumerate(c.description)])
c = conn.cursor()

%timeit c.execute('SELECT * FROM table').fetchall()
19.4 µs ± 75.6 ns per loop (mean ± std. dev. of 7 runs, 100000 loops each)

You decide :)

Javascript now has a specific built in object called Map, you can call as follows :

   var myMap = new Map()

You can update it with .set :

   myMap.set("key0","value")

This has the advantage of methods you can use to handle look ups, like the boolean .has

  myMap.has("key1"); // evaluates to false 

You can use this before calling .get on your Map object to handle looking up non-existent keys

Best-for-now Legacy Browser Frame Breaking Script

The other solutions did not worked for me. This one works on all browsers:

One way to defend against clickjacking is to include a "frame-breaker" script in each page that should not be framed. The following methodology will prevent a webpage from being framed even in legacy browsers, that do not support the X-Frame-Options-Header.

In the document HEAD element, add the following:

<style id="antiClickjack">body{display:none !important;}</style>

First apply an ID to the style element itself:

<script type="text/javascript">
   if (self === top) {
       var antiClickjack = document.getElementById("antiClickjack");
       antiClickjack.parentNode.removeChild(antiClickjack);
   } else {
       top.location = self.location;
   }
</script>

This way, everything can be in the document HEAD and you only need one method/taglib in your API.

Reference: https://www.codemagi.com/blog/post/194

I ran into the same symptom that @gpasse showed in his example. Here was my code...

<form...>
  <!-- various inputs with form submit --->

  <!-- button opens modal to show dynamic info -->
  <button id="myButton" class="btn btn-primary">Show Modal</button>
</form>

<div id="myModal" class="modal fade" ...>
</div>

<script>
  $( '#myButton' ).click( function() {
    $( '#myModal' ).modal();
  )};
</script>

As @Bhargav suggested, my issue was due to the button attempting to submit the form, and reloading the page. I changed the button to an <a> link as follows:

<a href="#" id="myButton" class="btn btn-primary">Show Modal</a>

...and it fixed the problem.

NOTE: I don't have enough reputation to simply add a comment or upvote yet, and I felt that I could add a little clarification.

private boolean isOnlyLetters(String s){
    char c=' ';
    boolean isGood=false, safe=isGood;
    int failCount=0;
    for(int i=0;i<s.length();i++){
        c = s.charAt(i);
        if(Character.isLetter(c))
            isGood=true;
        else{
            isGood=false;
            failCount+=1;
        }
    }
    if(failCount==0 && s.length()>0)
        safe=true;
    else
        safe=false;
    return safe;
}

I know it's a bit crowded. I was using it with my program and felt the desire to share it with people. It can tell if any character in a string is not a letter or not. Use it if you want something easy to clarify and look back on.

The request method getRequestDispatcher() can be used for referring to local servlets within single webapp.

Servlet context based getRequestDispatcher() method can used of referring servlets from other web applications deployed on SAME server.

Deleting and reinstalling Android Studio fixes the issue with the SDK.

Here's another method that's unorthodox, but works*.

I recently found myself in a situation where I'd checked in breaking code, knowing that I couldn't update our production code to it until all the integration work had taken place (in retrospect this was a bad decision, but we didn't expect to get stalled out, but other projects took precedence). That was several months ago, and the integration has been stalled for that entire time. Along comes a requirement to change the base code and get it into production last week without the breaking change.

Here's what we did:

After verifying that the new requirement doesn't break anything when using the revision before my check in, I made a copy of the working directory containing the new code. Then I deleted everything in the working directory and checked out the revision I wanted to it. Then I deleted all the files I'd just checked out, and copied in the files from the working copy. Then I committed that change, effectively wiping out the breaking change from the repository and getting the production code in place as the head revision. We still have the breaking change available, but it's no longer in the head revision so we can move forward to production.

*I don't recommend this method, but if you find yourself in a similar situation, it's a way out that's not too painful.

I found this solution where you can simply, check the server response code using status code.

Example :

$.ajax({
type : "POST",
url : "/package/callApi/createUser",
data : JSON.stringify(data),
contentType: "application/json; charset=UTF-8",
success: function (response) {  
    alert("Account created");
},
statusCode: {
    403: function() {
       // Only if your server returns a 403 status code can it come in this block. :-)
        alert("Username already exist");
    }
},
error: function (e) {
    alert("Server error - " + e);
} 
});

P4 is the cell I test for:

=IF(ISBLANK(P4),1,0)

Use JSON_UNESCAPED_UNICODE inside json_encode() if your php version >=5.4.

    public static void deleteLine() throws IOException {
        RandomAccessFile file = new RandomAccessFile("me.txt", "rw");
        String delete;
        String task="";
        byte []tasking;
        while ((delete = file.readLine()) != null) {
            if (delete.startsWith("BAD")) {
                continue;
            }
            task+=delete+"\n";
        }
        System.out.println(task);
        BufferedWriter writer = new BufferedWriter(new FileWriter("me.txt"));
        writer.write(task);
        file.close();
        writer.close();
    }

I agree that this var formattedString = string.replace(/'/g, "\\'"); works very well, but since I used this part of code in PHP with the framework Prado (you can register the js script in a PHP class) I needed this sample working inside double quotes.

The solution that worked for me is that you need to put three \ and escape the double quotes. "var string = \"l'avancement\"; var formattedString = string.replace(/'/g, \"\\\'\");"

I answer that question since I had trouble finding that three \ was the work around.

If you are using a string resource xml file (supports HTML tags), it can be done using<b> </b>, <i> </i> and <u> </u>.

<resources>
    <string name="your_string_here">
        This is an <u>underline</u>.
    </string>
</resources>

If you want to underline something from code use:

TextView tv = (TextView) view.findViewById(R.id.tv);
SpannableString content = new SpannableString("Content");
content.setSpan(new UnderlineSpan(), 0, content.length(), 0);
tv.setText(content);

Hope this helps

You can't access a MySQL DB from Android natively. EDIT: Actually you may be able to use JDBC, but it is not recommended (or may not work?) ... see Android JDBC not working: ClassNotFoundException on driver

See

http://www.helloandroid.com/tutorials/connecting-mysql-database

http://www.basic4ppc.com/forum/basic4android-getting-started-tutorials/8339-connect-android-mysql-database-tutorial.html

Android cannot connect directly to the database server. Therefore we need to create a simple web service that will pass the requests to the database and will return the response.

http://codeoncloud.blogspot.com/2012/03/android-mysql-client.html

For most [good] users this might be fine. But imagine you get a hacker that gets a hold of your program. I've decompiled my own applications and its scary what I've seen. What if they get your username / password to your database and wreak havoc? Bad.

In a VBA worksheet function UDF you use Application.Caller to get the range of cell(s) that contain the formula that called the UDF.

If the answer marked as correct does not work, it is because you need to identify yourself as a super user.

sudo gradle wrapper --gradle-version 2.13

It worked for me.

On my MacOS Catalina machine I discovered that an additional file had been created at /etc/apache2/users/my-username.conf where the default was

AllowOverride none

Changing that to All finally got things working for me. The challenge with Mac is that its hard to get to these directories with Finder so its easy not to spot this file

From the documentation:

NOTE: Every corner must (initially) be provided a corner radius greater than 1, or else no corners are rounded. If you want specific corners to not be rounded, a work-around is to use android:radius to set a default corner radius greater than 1, but then override each and every corner with the values you really want, providing zero ("0dp") where you don't want rounded corners.

E.g. you have to set an android:radius="<bigger than 1dp>" to be able to do what you want:

<corners 
    android:radius="2dp"
    android:bottomRightRadius="0dp" 
    android:topRightRadius="0dp"/> 

You can use the below snippet

BULK INSERT TextData
FROM 'E:\filefromabove.txt'
WITH
(
FIRSTROW = 2,
FIELDTERMINATOR = '|',  --CSV field delimiter
ROWTERMINATOR = '\n',   --Use to shift the control to next row
ERRORFILE = 'E:\ErrorRows.csv',
TABLOCK
)

your using this in a function, when you should be using the parameter.

You only use $(this) in callbacks... from selections like

$('a').click(function() {
   alert($(this).href);
})

In closing, the proper way (using your code example) would be to do this

obj.attr('id');

For me the problem was that the Facebook users I was using to test the app did not have its email address confirmed by Facebook.

My client had set up 2 fake accounts on Facebook and told me that they were not working. But he forgot to confirm the email addresses of those accounts (the emails Facebook sent went to his spam folder and he didn't notice).

Took me hours to find this, so I hope it helps somebody.

Cheers!

You just need to add an "A" record in the DNS manager on Godaddy. In that "A" record put your IP from dreamhost.

I know this works since I'm doing the very same thing.

just use getCheckedRadioButtonId() function to determine wether if anything is checked, if -1 is return, you can avoid toast appear

If you want the result as the nearest binary floating point number use float:

result = [float(x.strip(' "')) for x in A1]

If you want the result stored exactly use Decimal instead of float:

from decimal import Decimal
result = [Decimal(x.strip(' "')) for x in A1]

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

import csv

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

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

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

from itertools import repeat
import csv

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

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

The danger in using a backslash to end a line is that if whitespace is added after the backslash (which, of course, is very hard to see), the backslash is no longer doing what you thought it was.

See Python Idioms and Anti-Idioms (for Python 2 or Python 3) for more.

If you can edit all documents in aggregate :

"TimeStamp": {$toDecimal: {$toDate: "$Your Date"}}

And for the client, you set the query :

Date.parse("Your date".toISOString())

That's what makes you whole work with ISODate.

I found this just looking for a way to output simple columns. If you just need no-fuss columns, then you can use this:

print("Titlex\tTitley\tTitlez")
for x, y, z in data:
    print(x, "\t", y, "\t", z)

EDIT: I was trying to be as simple as possible, and thereby did some things manually instead of using the teams list. To generalize to the OP's actual question:

#Column headers
print("", end="\t")
for team in teams_list:
    print(" ", team, end="")
print()
# rows
for team, row in enumerate(data):
    teamlabel = teams_list[team]
    while len(teamlabel) < 9:
        teamlabel = " " + teamlabel
    print(teamlabel, end="\t")
    for entry in row:
        print(entry, end="\t")
    print()

Ouputs:

          Man Utd  Man City  T Hotspur
  Man Utd       1       2       1   
 Man City       0       1       0   
T Hotspur       2       4       2   

But this no longer seems any more simple than the other answers, with perhaps the benefit that it doesn't require any more imports. But @campkeith's answer already met that and is more robust as it can handle a wider variety of label lengths.

Check: http://www.php.net/require and http://www.php.net/include

controller_path holds the path of the controller used to serve the current view. (ie: admin/settings).

and

controller_name holds the name of the controller used to serve the current view. (ie: settings).

//in aspx page

<asp:TextBox ID="password" runat="server" TextMode="Password" />

//in MVC cshtml

@Html.Password("password", "", new { id = "password", Textmode = "Password" })

This worked for me:

h1 {
    display: inline;
    overflow: hidden;
}
div {
    position: relative;
    float: right;
}

It's similar to the approach of the media object, by Stubbornella.

Edit: As they comment below, you need to place the element that's going to float before the element that's going to wrap (the one in your first fiddle)

Sometimes in route.php you may have

Route::get('/{id}', 'Controller@show'..

written before

Route::get('/add', 'Controller@add'..

It can be empty method Controller::show() when you begin to develop your controller from scratch. In this case you will get empty blank page when requesting /add url. It happens because the request was handled by /{id} route, and its method returns nothing.

Just try to place /add route before /{id}

I stumbled over the same question and I've found a solution.

First make sure you upgrade to LESS 1.6 at least. You can use npm for that case.

Now you can use the following mixin:

.if (@condition, @property, @value) when (@condition = true){
     @{property}: @value;
 }

Since LESS 1.6 you are able to pass PropertyNames to Mixins as well. So for example you could just use:

.myHeadline {
   .if(@include-lineHeight,  line-height, '35px');
}

If @include-lineheight resolves to true LESS will print the line-height: 35px and it will skip the mixin if @include-lineheight is not true.

Use SharedPreferences, http://developer.android.com/reference/android/content/SharedPreferences.html

Here's a sample: http://developer.android.com/guide/topics/data/data-storage.html#pref

If the data structure is more complex or the data is large, use an Sqlite database; but for small amount of data and with a very simple data structure, I'd say, SharedPrefs will do and a DB might be overhead.

If you just wanted to change the example and put the table at the top, then loc='top' in the table declaration is what you need,

the_table = ax.table(cellText=cell_text,
                      rowLabels=rows,
                      rowColours=colors,
                      colLabels=columns,
                      loc='top')

Then adjusting the plot with,

plt.subplots_adjust(left=0.2, top=0.8)

A more flexible option is to put the table in its own axis using subplots,

import numpy as np
import matplotlib.pyplot as plt


fig, axs =plt.subplots(2,1)
clust_data = np.random.random((10,3))
collabel=("col 1", "col 2", "col 3")
axs[0].axis('tight')
axs[0].axis('off')
the_table = axs[0].table(cellText=clust_data,colLabels=collabel,loc='center')

axs[1].plot(clust_data[:,0],clust_data[:,1])
plt.show()

which looks like this,

You are then free to adjust the locations of the axis as required.

Basically, flush() cleans out your RAM buffer, its real power is that it lets you continue to write to it afterwards - but it shouldn't be thought of as the best/safest write to file feature. It's flushing your RAM for more data to come, that is all. If you want to ensure data gets written to file safely then use close() instead.

To write to a file you can use a byte array. The following example creates an empty ZIP file, which you can add files to:

[Byte[]] $zipHeader = 80, 75, 5, 6, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0
[System.IO.File]::WriteAllBytes("C:\My.zip", $zipHeader)

Or use:

[Byte[]] $text = [System.Text.Encoding]::UTF8.getBytes("Enabling feature XYZ.......")
[System.IO.File]::WriteAllBytes("C:\My.zip", $text)

Basically my code sends data to the next page like so:

**Referring Page**
$this = $_SERVER['PHP_SELF'];
echo "<a href='next_page.php?prev=$this'>Next Page</a>";

**Page with button**
$prev = $_GET['prev'];
echo "<a href='$prev'><button id='back'>Back</button></a>";

I have been hasseling with that as other folks have.

I used the criteria;

=countif(matchingList,C2)=0

where matchingList is the list that i am using as a filter.

have a look at this

http://www.youtube.com/watch?v=x47VFMhRLnM&list=PL63A7644FE57C97F4&index=30

The trick i found is that normally you would have the column heading in the criteria matching the data column heading. this will not work for criteria that is a formula.

What I found was if I left the column heading blank for only the criteria that has the countif formula in the advanced filter works. If I have the column heading i.e. the column heading for column C2 in my formula example then the filter return no output.

Hope this helps

for root, dirs, files in os.walk(directory):
    for file in files:
        floc = file
        im = Image.open(str(directory) + '\\' + floc)
        pix = np.array(im.getdata())
        pixels.append(pix)
        labels.append(1)   # append(i)???

So far ok. But you want to leave pixels as a list until you are done with the iteration.

pixels = np.array(pixels)
labels = np.array(labels)

You had this indention right in your other question. What happened? previous

Iterating, collecting values in a list, and then at the end joining things into a bigger array is the right way. To make things clear I often prefer to use notation like:

alist = []
for ..
    alist.append(...)
arr = np.array(alist)

If names indicate something about the nature of the object I'm less likely to get errors like yours.

I don't understand what you are trying to do with traindata. I doubt if you need to build it during the loop. pixels and labels have the basic information.

That

traindata = np.array([traindata[i][i],traindata[1]], dtype=object)

comes from the previous question. I'm not sure you understand that answer.

traindata = []
traindata.append(pixels)
traindata.append(labels)

if done outside the loop is just

traindata = [pixels, labels]

labels is a 1d array, a bunch of 1s (or [0,1,2,3...] if my guess is right). pixels is a higher dimension array. What is its shape?

Stop right there. There's no point in turning that list into an array. You can save the list with pickle.

You are copying code from an earlier question, and getting the formatting wrong. cPickle very large amount of data

This solution will only work if you have tree installed on your system. However I'm leaving this solution here just in case it helps someone else out.

You can tell tree to output the tree structure as XML (tree -X) or JSON (tree -J). JSON of course can be parsed directly with python and XML can easily be read with lxml.

With the following directory structure as an example:

[sri@localhost Projects]$ tree --charset=ascii bands

The accepted answer didn't solve my problem.

If you are using Multidex, your Application should extends MultiDexApplication instead of Application.

MyApplication.java

public class MyApplication extends MultiDexApplication{
     ...
}

AndroidManifest.xml

<application
      android:name="your.package.name.MyApplication"
      android:allowBackup="true"
      android:icon="@mipmap/ic_launcher"
      ...
      />

Hope it helps.

I came across a similar issue but instead of changing the regedit I decided to change the Chrome settings

Try the following steps

1. In the chrome browser type: chrome://plugins/
2. Click on + Details (top right corner) to expand all the plugin details.
3. Find Java and click on Disable for the path(s) that you don't want to be used.

You might have to restart the browser to see the changes. This also assumes that the Java that you have enabled is the latest Java.

Hope this helps

Please check: http://man7.org/linux/man-pages/man5/proc.5.html

address           perms offset  dev   inode       pathname
00400000-00452000 r-xp 00000000 08:02 173521      /usr/bin/dbus-daemon

The address field is the address space in the process that the mapping occupies.

The perms field is a set of permissions:

 r = read
 w = write
 x = execute
 s = shared
 p = private (copy on write)

The offset field is the offset into the file/whatever;

dev is the device (major:minor);

inode is the inode on that device.0 indicates that no inode is associated with the memoryregion, as would be the case with BSS (uninitialized data).

The pathname field will usually be the file that is backing the mapping. For ELF files, you can easily coordinate with the offset field by looking at the Offset field in the ELF program headers (readelf -l).

Under Linux 2.0, there is no field giving pathname.

the secure way is encrypt your sensitive data by AES and the encryption key is derivation by password-based key derivation function (PBE), the master password used to encrypt/decrypt the encrypt key for AES.

master password -> secure key-> encrypt data by the key

You can use pbkdf2

from PBKDF2 import PBKDF2
from Crypto.Cipher import AES
import os
salt = os.urandom(8)    # 64-bit salt
key = PBKDF2("This passphrase is a secret.", salt).read(32) # 256-bit key
iv = os.urandom(16)     # 128-bit IV
cipher = AES.new(key, AES.MODE_CBC, iv)

make sure to store the salt/iv/passphrase , and decrypt using same salt/iv/passphase

Weblogic used similar approach to protect passwords in config files

You should use the Spring Boot Maven Plugin:

<project>  
  ...
  <build>
    ...
    <plugins>
      ...
      <plugin>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-maven-plugin</artifactId>
        <version>1.5.1.RELEASE</version>
        <configuration>
          <profiles>
            <profile>foo</profile>
            <profile>bar</profile>
          </profiles>
        </configuration>
        ...
      </plugin>
      ...
    </plugins>
    ...
  </build>
  ...
</project>

SQL Server 2012 and Later

Just use Try_Convert instead:

TRY_CONVERT takes the value passed to it and tries to convert it to the specified data_type. If the cast succeeds, TRY_CONVERT returns the value as the specified data_type; if an error occurs, null is returned. However if you request a conversion that is explicitly not permitted, then TRY_CONVERT fails with an error.

Read more about Try_Convert.

SQL Server 2008 and Earlier

The traditional way of handling this is by guarding every expression with a case statement so that no matter when it is evaluated, it will not create an error, even if it logically seems that the CASE statement should not be needed. Something like this:

SELECT
   Account_Code =
      Convert(
         bigint, -- only gives up to 18 digits, so use decimal(20, 0) if you must
         CASE
         WHEN X.Account_Code LIKE '%[^0-9]%' THEN NULL
         ELSE X.Account_Code
         END
      ),
   A.Descr
FROM dbo.Account A
WHERE
   Convert(
      bigint,
      CASE
      WHEN X.Account_Code LIKE '%[^0-9]%' THEN NULL
      ELSE X.Account_Code
      END
   ) BETWEEN 503100 AND 503205

However, I like using strategies such as this with SQL Server 2005 and up:

SELECT
   Account_Code = Convert(bigint, X.Account_Code),
   A.Descr
FROM
   dbo.Account A
   OUTER APPLY (
      SELECT A.Account_Code WHERE A.Account_Code NOT LIKE '%[^0-9]%'
   ) X
WHERE
   Convert(bigint, X.Account_Code) BETWEEN 503100 AND 503205

What this does is strategically switch the Account_Code values to NULL inside of the X table when they are not numeric. I initially used CROSS APPLY but as Mikael Eriksson so aptly pointed out, this resulted in the same error because the query parser ran into the exact same problem of optimizing away my attempt to force the expression order (predicate pushdown defeated it). By switching to OUTER APPLY it changed the actual meaning of the operation so that X.Account_Code could contain NULL values within the outer query, thus requiring proper evaluation order.

You may be interested to read Erland Sommarskog's Microsoft Connect request about this evaluation order issue. He in fact calls it a bug.

There are additional issues here but I can't address them now.

P.S. I had a brainstorm today. An alternate to the "traditional way" that I suggested is a SELECT expression with an outer reference, which also works in SQL Server 2000. (I've noticed that since learning CROSS/OUTER APPLY I've improved my query capability with older SQL Server versions, too--as I am getting more versatile with the "outer reference" capabilities of SELECT, ON, and WHERE clauses!)

SELECT
   Account_Code =
      Convert(
         bigint,
         (SELECT A.AccountCode WHERE A.Account_Code NOT LIKE '%[^0-9]%')
      ),
   A.Descr
FROM dbo.Account A
WHERE
   Convert(
      bigint,
      (SELECT A.AccountCode WHERE A.Account_Code NOT LIKE '%[^0-9]%')
   ) BETWEEN 503100 AND 503205

It's a lot shorter than the CASE statement.

You can also try dism /online /Enable-Feature /FeatureName:TelnetClient

Run this command with "Run as an administrator"

Reference

You just have override the getView method of ArrayAdapter

ArrayAdapter<String> adapter = new ArrayAdapter<String>(getApplicationContext(), 
        android.R.layout.simple_list_item_1, mStringList) {
    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        View view = super.getView(position, convertView, parent);
        TextView text = (TextView) view.findViewById(android.R.id.text1);
        text.setTextColor(Color.BLACK);
        return view;
    }
};

ok, you may use substr in correlation to instr to find the starting position of your string

select 
  dbms_lob.substr(
       product_details, 
       length('NEW.PRODUCT_NO'), --amount
       dbms_lob.instr(product_details,'NEW.PRODUCT_NO') --offset
       ) 
from my_table
where dbms_lob.instr(product_details,'NEW.PRODUCT_NO')>=1;

Chain both class selectors (without a space in between):

.foo.bar {
    /* Styles for element(s) with foo AND bar classes */
}

If you still have to deal with ancient browsers like IE6, be aware that it doesn't read chained class selectors correctly: it'll only read the last class selector (.bar in this case) instead, regardless of what other classes you list.

To illustrate how other browsers and IE6 interpret this, consider this CSS:

* {
    color: black;
}

.foo.bar {
    color: red;
}

Output on supported browsers is:

<div class="foo">Hello Foo</div>       <!-- Not selected, black text [1] -->
<div class="foo bar">Hello World</div> <!-- Selected, red text [2] -->
<div class="bar">Hello Bar</div>       <!-- Not selected, black text [3] -->

Output on IE6 is:

<div class="foo">Hello Foo</div>       <!-- Not selected, black text [1] -->
<div class="foo bar">Hello World</div> <!-- Selected, red text [2] -->
<div class="bar">Hello Bar</div>       <!-- Selected, red text [2] -->

Footnotes:

• Supported browsers:
  1. Not selected as this element only has class foo.
  2. Selected as this element has both classes foo and bar.
  3. Not selected as this element only has class bar.
     
     
• IE6:
  1. Not selected as this element doesn't have class bar.
  2. Selected as this element has class bar, regardless of any other classes listed.

As explained above, a Class cannot be static unless it's a member of another Class.

If you're looking to design a class "of which there cannot be multiple instances", you may want to look into the "Singleton" design pattern.

Beginner Singleton info here.

Caveat:

If you are thinking of using the singleton pattern, resist with all your might. It is one of the easiest DesignPatterns to understand, probably the most popular, and definitely the most abused. (source: JavaRanch as linked above)

Here are some example to iterate over integer range and string:

#(initial,final but not included,gap)
for i in range(1,10,2): 
  print(i); 
1,3,5,7,9

# (initial, final but not included)  
# note: 4 not included
for i in range (1,4): 
   print(i);
1,2,3 

#note: 5 not included
for i in range (5):
  print (i);
0,1,2,3,4 

# you can also iterate over strings
myList = ["ml","ai","dl"];  

for i in myList:
  print(i);
output:  ml,ai,dl

There are several ways that you can transform data from multiple rows into columns.

Using PIVOT

In SQL Server you can use the PIVOT function to transform the data from rows to columns:

select Firstname, Amount, PostalCode, LastName, AccountNumber
from
(
  select value, columnname
  from yourtable
) d
pivot
(
  max(value)
  for columnname in (Firstname, Amount, PostalCode, LastName, AccountNumber)
) piv;

See Demo.

Pivot with unknown number of columnnames

If you have an unknown number of columnnames that you want to transpose, then you can use dynamic SQL:

DECLARE @cols AS NVARCHAR(MAX),
    @query  AS NVARCHAR(MAX)

select @cols = STUFF((SELECT ',' + QUOTENAME(ColumnName) 
                    from yourtable
                    group by ColumnName, id
                    order by id
            FOR XML PATH(''), TYPE
            ).value('.', 'NVARCHAR(MAX)') 
        ,1,1,'')

set @query = N'SELECT ' + @cols + N' from 
             (
                select value, ColumnName
                from yourtable
            ) x
            pivot 
            (
                max(value)
                for ColumnName in (' + @cols + N')
            ) p '

exec sp_executesql @query;

See Demo.

Using an aggregate function

If you do not want to use the PIVOT function, then you can use an aggregate function with a CASE expression:

select
  max(case when columnname = 'FirstName' then value end) Firstname,
  max(case when columnname = 'Amount' then value end) Amount,
  max(case when columnname = 'PostalCode' then value end) PostalCode,
  max(case when columnname = 'LastName' then value end) LastName,
  max(case when columnname = 'AccountNumber' then value end) AccountNumber
from yourtable

See Demo.

Using multiple joins

This could also be completed using multiple joins, but you will need some column to associate each of the rows which you do not have in your sample data. But the basic syntax would be:

select fn.value as FirstName,
  a.value as Amount,
  pc.value as PostalCode,
  ln.value as LastName,
  an.value as AccountNumber
from yourtable fn
left join yourtable a
  on fn.somecol = a.somecol
  and a.columnname = 'Amount'
left join yourtable pc
  on fn.somecol = pc.somecol
  and pc.columnname = 'PostalCode'
left join yourtable ln
  on fn.somecol = ln.somecol
  and ln.columnname = 'LastName'
left join yourtable an
  on fn.somecol = an.somecol
  and an.columnname = 'AccountNumber'
where fn.columnname = 'Firstname'

Let me add some more use case of the square-bracket notation. If you want to access a property say x-proxy in a object, then - will be interpreted wrongly. Their are some other cases too like space, dot, etc., where dot operation will not help you. Also if u have the key in a variable then only way to access the value of the key in a object is by bracket notation. Hope you get some more context.

is it possible to export without looping through all records

For a range in Excel with a large number of rows you may see some performance improvement if you create an Access.Application object in Excel and then use it to import the Excel data into Access. The code below is in a VBA module in the same Excel document that contains the following test data

Option Explicit

Sub AccImport()
    Dim acc As New Access.Application
    acc.OpenCurrentDatabase "C:\Users\Public\Database1.accdb"
    acc.DoCmd.TransferSpreadsheet _
            TransferType:=acImport, _
            SpreadSheetType:=acSpreadsheetTypeExcel12Xml, _
            TableName:="tblExcelImport", _
            Filename:=Application.ActiveWorkbook.FullName, _
            HasFieldNames:=True, _
            Range:="Folio_Data_original$A1:B10"
    acc.CloseCurrentDatabase
    acc.Quit
    Set acc = Nothing
End Sub

Beware the elephant trap:

I saw no mention of this in this discussion. [Access 2010]

How ACCESS/VBA handles errors in CLASS objects is determined by a configurable option:

Add a checkbox to the exit dialog to launch the app, or the helpfile.

...

<!-- CA to launch the exe after install -->
<CustomAction Id          ="CA.StartAppOnExit"
              FileKey     ="YourAppExeId"
              ExeCommand  =""
              Execute     ="immediate"
              Impersonate ="yes"
              Return      ="asyncNoWait" />

<!-- CA to launch the help file -->
<CustomAction Id         ="CA.LaunchHelp"
              Directory  ="INSTALLDIR"
              ExeCommand ='[WindowsFolder]hh.exe IirfGuide.chm'
              Execute    ="immediate"
              Return     ="asyncNoWait" />

<Property Id="WIXUI_EXITDIALOGOPTIONALCHECKBOXTEXT"
          Value="Launch MyApp when setup exits." />

<UI>
  <Publish Dialog  ="ExitDialog"
           Control ="Finish"
           Order   ="1"
           Event   ="DoAction"
           Value   ="CA.StartAppOnExit">WIXUI_EXITDIALOGOPTIONALCHECKBOXTEXT</Publish>
</UI>

If you do it this way, the "standard" appearance isn't quite right. The checkbox is always a gray background, while the dialog is white:

alt text http://www.dizzymonkeydesign.com/blog/misc/adding-and-customizing-dlgs-in-wix-3/images/exit_dlg_1.gif

One way around this is to specify your own custom ExitDialog, with a differently-located checkbox. This works, but seems like a lot of work just to change the color of one control. Another way to solve the same thing is to post-process the generated MSI to change the X,Y fields in the Control table for that particular CheckBox control. The javascript code looks like this:

var msiOpenDatabaseModeTransact = 1;
var filespec = WScript.Arguments(0);
var installer = new ActiveXObject("WindowsInstaller.Installer");
var database = installer.OpenDatabase(filespec, msiOpenDatabaseModeTransact);
var sql = "UPDATE `Control` SET `Control`.`Height` = '18', `Control`.`Width` = '170'," +
          " `Control`.`Y`='243', `Control`.`X`='10' " +
          "WHERE `Control`.`Dialog_`='ExitDialog' AND " + 
          "  `Control`.`Control`='OptionalCheckBox'";
var view = database.OpenView(sql);
view.Execute();
view.Close();
database.Commit();

Running this code as a command-line script (using cscript.exe) after the MSI is generated (from light.exe) will produce an ExitDialog that looks more professional:

There is a well know relation between time and space complexity.

First of all, time is an obvious bound to space consumption: in time t you cannot reach more than O(t) memory cells. This is usually expressed by the inclusion

                            DTime(f) ? DSpace(f)

where DTime(f) and DSpace(f) are the set of languages recognizable by a deterministic Turing machine in time (respectively, space) O(f). That is to say that if a problem can be solved in time O(f), then it can also be solved in space O(f).

Less evident is the fact that space provides a bound to time. Suppose that, on an input of size n, you have at your disposal f(n) memory cells, comprising registers, caches and everything. After having written these cells in all possible ways you may eventually stop your computation, since otherwise you would reenter a configuration you already went through, starting to loop. Now, on a binary alphabet, f(n) cells can be written in 2^f(n) different ways, that gives our time upper bound: either the computation will stop within this bound, or you may force termination, since the computation will never stop.

This is usually expressed in the inclusion

                          DSpace(f) ? Dtime(2^(cf))

for some constant c. the reason of the constant c is that if L is in DSpace(f) you only know that it will be recognized in Space O(f), while in the previous reasoning, f was an actual bound.

The above relations are subsumed by stronger versions, involving nondeterministic models of computation, that is the way they are frequently stated in textbooks (see e.g. Theorem 7.4 in Computational Complexity by Papadimitriou).

I recommend that you try to use Postgres.app. (http://postgresapp.com) This way you can easily turn Postgres on and off on your Mac. Once you do, add the path to Postgres to your .profile file by appending the following:

PATH="/Applications/Postgres.app/Contents/Versions/latest/bin:$PATH"

Only after you added Postgres to your path you can try to install psycopg2 either within a virtual environment (using pip) or into your global site packages.

I tried this:

import pandas as p
import numpy as n

closingValue = p.read_csv("<FILENAME>", usecols=[4], dtype=float)
print(closingValue)

How to add single item. This is not very effective but follows what you are asking for:

x = p.Series()
N = 4
for i in xrange(N):
   x = x.set_value(i, i**2)

produces x:

0    0
1    1
2    4
3    9

Obviously there are better ways to generate this series in only one shot.

For your second question check answer and references of SO question add one row in a pandas.DataFrame.

Try redirecting the output to Out-Null. Like so,

$key = & 'gpg' --decrypt "secret.gpg" --quiet --no-verbose | out-null

You have to use '"+texbox1.Text+"','"+texbox2.Text+"','"+texbox3.Text+"'

Instead of "+texbox1.Text+","+texbox2.Text+","+texbox3.Text+"

Notice the extra single quotes.

Please see this:

<div ng-repeat="division in divisions | orderBy:['group','sub']">{{division.group}}-{{division.sub}}</div>

This helped me remove background color, hope it helps someone. setBackgroundColor(Color.TRANSPARENT)

You may also use this.Resources["mykey"]. I guess that is not much better than your own suggestion.

Make sure you put the onSubmit attribute on the form not the button in case you have a from.

<form onSubmit={e => e.preventDefault()}>
    <button onClick={this.handleClick}>Click Me</button>
</form>

Make sure to change the button onClick attribute to your custom function.

For this you can use the readonly modifier. Object properties which are readonly can only be assigned during initialization of the object.

Example in classes:

class Circle {
  readonly radius: number;

  constructor(radius: number) {
    this.radius = radius;
  }

  get area() {
    return Math.PI * this.radius * 2;
  }
}

const circle = new Circle(12);
circle.radius = 12; // Cannot assign to 'radius' because it is a read-only property.

Example in Object literals:

type Rectangle = {
  readonly height: number;
  readonly width: number;
};

const square: Rectangle = { height: 1, width: 2 };
square.height = 5 // Cannot assign to 'height' because it is a read-only property

It's also worth knowing that the readonly modifier is purely a typescript construct and when the TS is compiled to JS the construct will not be present in the compiled JS. When we are modifying properties which are readonly the TS compiler will warn us about it (it is valid JS).

Assuming you're on Windows (if so you should tag your question as such!), on this MSDN page you can find the source for a simple, useful HRTimer C++ class that wraps the needed system calls to do something very close to what you require (it would be easy to add a GetTicks() method to it, in particular, to do exactly what you require).

On non-Windows platforms, there's no QueryPerformanceCounter function, so the solution won't be directly portable. However, if you do wrap it in a class such as the above-mentioned HRTimer, it will be easier to change the class's implementation to use what the current platform is indeed able to offer (maybe via Boost or whatever!).

In general, git reset's function is to take the current branch and reset it to point somewhere else, and possibly bring the index and work tree along. More concretely, if your master branch (currently checked out) is like this:

- A - B - C (HEAD, master)

and you realize you want master to point to B, not C, you will use git reset B to move it there:

- A - B (HEAD, master)      # - C is still here, but there's no branch pointing to it anymore

Digression: This is different from a checkout. If you'd run git checkout B, you'd get this:

- A - B (HEAD) - C (master)

You've ended up in a detached HEAD state. HEAD, work tree, index all match B, but the master branch was left behind at C. If you make a new commit D at this point, you'll get this, which is probably not what you want:

- A - B - C (master)
       \
        D (HEAD)

Remember, reset doesn't make commits, it just updates a branch (which is a pointer to a commit) to point to a different commit. The rest is just details of what happens to your index and work tree.

Use cases

I cover many of the main use cases for git reset within my descriptions of the various options in the next section. It can really be used for a wide variety of things; the common thread is that all of them involve resetting the branch, index, and/or work tree to point to/match a given commit.

Things to be careful of

• --hard can cause you to really lose work. It modifies your work tree.

• git reset [options] commit can cause you to (sort of) lose commits. In the toy example above, we lost commit C. It's still in the repo, and you can find it by looking at git reflog show HEAD or git reflog show master, but it's not actually accessible from any branch anymore.

• Git permanently deletes such commits after 30 days, but until then you can recover C by pointing a branch at it again (git checkout C; git branch <new branch name>).

Arguments

Paraphrasing the man page, most common usage is of the form git reset [<commit>] [paths...], which will reset the given paths to their state from the given commit. If the paths aren't provided, the entire tree is reset, and if the commit isn't provided, it's taken to be HEAD (the current commit). This is a common pattern across git commands (e.g. checkout, diff, log, though the exact semantics vary), so it shouldn't be too surprising.

For example, git reset other-branch path/to/foo resets everything in path/to/foo to its state in other-branch, git reset -- . resets the current directory to its state in HEAD, and a simple git reset resets everything to its state in HEAD.

The main work tree and index options

There are four main options to control what happens to your work tree and index during the reset.

Remember, the index is git's "staging area" - it's where things go when you say git add in preparation to commit.

• --hard makes everything match the commit you've reset to. This is the easiest to understand, probably. All of your local changes get clobbered. One primary use is blowing away your work but not switching commits: git reset --hard means git reset --hard HEAD, i.e. don't change the branch but get rid of all local changes. The other is simply moving a branch from one place to another, and keeping index/work tree in sync. This is the one that can really make you lose work, because it modifies your work tree. Be very very sure you want to throw away local work before you run any reset --hard.

• --mixed is the default, i.e. git reset means git reset --mixed. It resets the index, but not the work tree. This means all your files are intact, but any differences between the original commit and the one you reset to will show up as local modifications (or untracked files) with git status. Use this when you realize you made some bad commits, but you want to keep all the work you've done so you can fix it up and recommit. In order to commit, you'll have to add files to the index again (git add ...).

• --soft doesn't touch the index or work tree. All your files are intact as with --mixed, but all the changes show up as changes to be committed with git status (i.e. checked in in preparation for committing). Use this when you realize you've made some bad commits, but the work's all good - all you need to do is recommit it differently. The index is untouched, so you can commit immediately if you want - the resulting commit will have all the same content as where you were before you reset.

• --merge was added recently, and is intended to help you abort a failed merge. This is necessary because git merge will actually let you attempt a merge with a dirty work tree (one with local modifications) as long as those modifications are in files unaffected by the merge. git reset --merge resets the index (like --mixed - all changes show up as local modifications), and resets the files affected by the merge, but leaves the others alone. This will hopefully restore everything to how it was before the bad merge. You'll usually use it as git reset --merge (meaning git reset --merge HEAD) because you only want to reset away the merge, not actually move the branch. (HEAD hasn't been updated yet, since the merge failed)

  To be more concrete, suppose you've modified files A and B, and you attempt to merge in a branch which modified files C and D. The merge fails for some reason, and you decide to abort it. You use git reset --merge. It brings C and D back to how they were in HEAD, but leaves your modifications to A and B alone, since they weren't part of the attempted merge.

Want to know more?

I do think man git reset is really quite good for this - perhaps you do need a bit of a sense of the way git works for them to really sink in though. In particular, if you take the time to carefully read them, those tables detailing states of files in index and work tree for all the various options and cases are very very helpful. (But yes, they're very dense - they're conveying an awful lot of the above information in a very concise form.)

Strange notation

The "strange notation" (HEAD^ and HEAD~1) you mention is simply a shorthand for specifying commits, without having to use a hash name like 3ebe3f6. It's fully documented in the "specifying revisions" section of the man page for git-rev-parse, with lots of examples and related syntax. The caret and the tilde actually mean different things:

• HEAD~ is short for HEAD~1 and means the commit's first parent. HEAD~2 means the commit's first parent's first parent. Think of HEAD~n as "n commits before HEAD" or "the nth generation ancestor of HEAD".
• HEAD^ (or HEAD^1) also means the commit's first parent. HEAD^2 means the commit's second parent. Remember, a normal merge commit has two parents - the first parent is the merged-into commit, and the second parent is the commit that was merged. In general, merges can actually have arbitrarily many parents (octopus merges).
• The ^ and ~ operators can be strung together, as in HEAD~3^2, the second parent of the third-generation ancestor of HEAD, HEAD^^2, the second parent of the first parent of HEAD, or even HEAD^^^, which is equivalent to HEAD~3.

The answers posted here all didn't quite work for me. They mainly skipped signing embedded frameworks (or including the entitlements).

Here's what's worked for me (it assumes that one ipa file exists is in the current directory):

PROVISION="/path/to/file.mobileprovision"
CERTIFICATE="Name of certificate: To sign with" # must be in the keychain

unzip -q *.ipa
rm -rf Payload/*.app/_CodeSignature/

# Replace embedded provisioning profile
cp "$PROVISION" Payload/*.app/embedded.mobileprovision

# Extract entitlements from app
codesign -d --entitlements :entitlements.plist Payload/*.app/

# Re-sign embedded frameworks
codesign -f -s "$CERTIFICATE" --entitlements entitlements.plist Payload/*.app/Frameworks/*

# Re-sign the app (with entitlements)
codesign -f -s "$CERTIFICATE" --entitlements entitlements.plist Payload/*.app/

zip -qr resigned.ipa Payload

# Cleanup
rm entitlements.plist
rm -r Payload/

No need for array. Just use something like this:

Sub ARRAYER()

    Dim Rng As Range
    Dim Number_of_Sims As Long
    Dim i As Long
    Number_of_Sims = 10

    Set Rng = Range("C4:G4")
    For i = 1 To Number_of_Sims
       Rng.Offset(i, 0).Value = Rng.Value
       Worksheets("Sheetname").Calculate   'replacing Sheetname with name of your sheet
    Next

End Sub

not really sure what you're doing exactly via the context of your code but...

why make the listOfTopicAuthors variable at all?

List<String> list = Arrays.asList((....).toArray( new String[0] ) );

the "...." represents however your set came into play, whether it's new or came from another location.

Modules Preconditions:

The IIS core engine uses preconditions to determine when to enable a particular module. Performance reasons, for example, might determine that you only want to execute managed modules for requests that also go to a managed handler. The precondition in the following example (precondition="managedHandler") only enables the forms authentication module for requests that are also handled by a managed handler, such as requests to .aspx or .asmx files:

<add name="FormsAuthentication" type="System.Web.Security.FormsAuthenticationModule" preCondition="managedHandler" />

If you remove the attribute precondition="managedHandler", Forms Authentication also applies to content that is not served by managed handlers, such as .html, .jpg, .doc, but also for classic ASP (.asp) or PHP (.php) extensions. See "How to Take Advantage of IIS Integrated Pipeline" for an example of enabling ASP.NET modules to run for all content.

You can also use a shortcut to enable all managed (ASP.NET) modules to run for all requests in your application, regardless of the "managedHandler" precondition.

To enable all managed modules to run for all requests without configuring each module entry to remove the "managedHandler" precondition, use the runAllManagedModulesForAllRequests property in the <modules> section:

<modules runAllManagedModulesForAllRequests="true" />    

When you use this property, the "managedHandler" precondition has no effect and all managed modules run for all requests.

I like to set the 'line-height' in the css for the divs to get them to line up properly. Here is an example of how I do it using asp and css:

ASP:

<div id="profileRow1">
    <div id="profileRow1Col1" class="righty">
        <asp:Label ID="lblCreatedDateLabel" runat="server" Text="Date Created:"></asp:Label><br />
        <asp:Label ID="lblLastLoginDateLabel" runat="server" Text="Last Login Date:"></asp:Label><br />
        <asp:Label ID="lblUserIdLabel" runat="server" Text="User ID:"></asp:Label><br />
        <asp:Label ID="lblUserNameLabel" runat="server" Text="Username:"></asp:Label><br />
        <asp:Label ID="lblFirstNameLabel" runat="server" Text="First Name:"></asp:Label><br />
        <asp:Label ID="lblLastNameLabel" runat="server" Text="Last Name:"></asp:Label><br />
    </div>
    <div id="profileRow1Col2">
        <asp:Label ID="lblCreatedDate" runat="server" Text="00/00/00 00:00:00"></asp:Label><br />
        <asp:Label ID="lblLastLoginDate" runat="server" Text="00/00/00 00:00:00"></asp:Label><br />
        <asp:Label ID="lblUserId" runat="server" Text="UserId"></asp:Label><br />
        <asp:TextBox ID="txtUserName" runat="server"></asp:TextBox><br />
        <asp:TextBox ID="txtFirstName" runat="server"></asp:TextBox><br />
        <asp:TextBox ID="txtLastName" runat="server"></asp:TextBox><br />
    </div>
</div>

And here is the code in the CSS file to make all of the above fields look nice and neat:

#profileRow1{width:100%;line-height:40px;}
#profileRow1Col1{float:left; width:25%; margin-right:20px;}
#profileRow1Col2{float:left; width:25%;}
.righty{text-align:right;}

you can basically pull everything but the DIV tags and replace with your own content.

Trust me when I say it looks aligned the way the image in the original post does!

I think one error in the original code might have been that it had:

$message = echo getRequestURI();

instead of:

$message = getRequestURI();

(The code has since been edited though.)

If you want to get and set the property both, you can use this in C#7:

GetString(
    inputString,
    (() => client.WorkPhone, x => client.WorkPhone = x))

void GetString(string inValue, (Func<string> get, Action<string> set) outValue)
{
    if (!string.IsNullOrEmpty(outValue))
    {
        outValue.set(inValue);
    }
}

Use this ^[a-zA-Z0-9_]*$

See here for more info.

Use render method:

<Route exact path="/details/:id" render={(props)=>{
    <DetailsPage id={props.match.params.id}/>
}} />

And you should be able to access the id using:

this.props.id

Inside the DetailsPage component

If you had generate a SSH-key with passphrase and then you forget your passphrase for this SSH-key,there's no way to recover it, You'll need to generate a brand new SSH keypair or switch to HTTPS cloning so you can use your GitHub password instead.

BUT,there are exceptions

If you configured your SSH passphrase with the OS X Keychain, you may be able to recover it.

1. In Finder, search for the Keychain Access app.
2. In Keychain Access, search for SSH.
3. Double click on the entry for your SSH key to open a new dialog box.
4. Keychain access dialogIn the lower-left corner, select Show password.
5. You'll be prompted for your administrative password. Type it into the "Keychain Access" dialog box.
6. Your password will be revealed.

Refer to Github help - How do I recover my SSH key passphrase?

I Tested Now and Work like a Charm

Coming on this old thread i wanted to stress that

1°) utility functions may (should?) be added to the rootscope via module.run. There is no need to instanciate a specific root level controller for this purpose.

angular.module('myApp').run(function($rootScope){
  $rootScope.isNotString = function(str) {
   return (typeof str !== "string");
  }
});

2°) If you organize your code into separate modules you should use angular services or factory and then inject them into the function passed to the run block, as follow:

angular.module('myApp').factory('myHelperMethods', function(){
  return {
    isNotString: function(str) {
      return (typeof str !== 'string');
    }
  }
});

angular.module('myApp').run(function($rootScope, myHelperMethods){ 
  $rootScope.helpers = myHelperMethods;
});

3°) My understanding is that in views, for most of the cases you need these helper functions to apply some kind of formatting to strings you display. What you need in this last case is to use angular filters

And if you have structured some low level helper methods into angular services or factory, just inject them within your filter constructor :

angular.module('myApp').filter('myFilter', function(myHelperMethods){ 
  return function(aString){
    if (myHelperMethods.isNotString(aString)){
      return 
    }
    else{
      // something else 
    }
  }
);

And in your view :

{{ aString | myFilter }}   

1. find out commit id

   git reflog

2. recover local branch you deleted by mistake

   git branch need-recover-branch-name commitId

3. push need-recover-branch-name again if you deleted remote branch too before

   git push origin need-recover-branch-name

1. Open up SQL Server Management Studio and connect to your database server.
2. Right Click The Database Server and click Properties.
3. Set the Server Authentication to SQL Server and Windows Authentication Mode.

You don't need to add extra two classes (button button-primary), you just use the child class (button-primary) with css and it will apply parent as well as child css class. Here is the link:

Thanks to Jacob Lichner!

You are not printing the array, you are printing the value of temp - which is only half the array...

There's now a drop down (at least since VS 2017.3.5) where you can specifically select C++17. The available options are (under project > Properties > C/C++ > Language > C++ Language Standard)

• ISO C++14 Standard. msvc command line option: /std:c++14
• ISO C++17 Standard. msvc command line option: /std:c++17
• The latest draft standard. msvc command line option: /std:c++latest

(I bet, once C++20 is out and more fully supported by Visual Studio it will be /std:c++20)

If you want to pass the type, than the equivalent in Java would be

java.lang.Class

If you want to use a weakly typed method, then you would simply use

java.lang.Object

and the corresponding operator

instanceof

e.g.

private void foo(Object o) {

  if(o instanceof String) {

  }

}//foo

However, in Java there are primitive types, which are not classes (i.e. int from your example), so you need to be careful.

The real question is what you actually want to achieve here, otherwise it is difficult to answer:

Or is there a better way?

CREATE TABLE Employees
(
    Id int,
    Name varchar(50) not null,
    Photo varbinary(max) not null
)


INSERT INTO Employees (Id, Name, Photo) 
SELECT 10, 'John', BulkColumn 
FROM Openrowset( Bulk 'C:\photo.bmp', Single_Blob) as EmployeePicture

I solved the same problem. I've just added JSTL-1.2.jar to /apache-tomcat-x.x.x/lib and set scope to provided in maven pom.xml:

 <dependency>
     <groupId>jstl</groupId>
     <artifactId>jstl</artifactId>
     <version>1.2</version>
     <scope>provided</scope>
 </dependency>

I have solved this issue as follows:

removed from chrome extension and install ext again. It will work ISA

As far as I'm aware, you've got three options to install zsh on Mac OS X:

• Pre-built binary. The only one I know of is the one that ships with OS X; this is probably what you're running now.
• Use a package system (Ports, Homebrew).
• Install from source. Last time I did this it wasn't too difficult (./configure, make, make install).

you cannot set target attribute to div, becacuse div does not know how to handle http requests. instead of you set target attribute for link tag.

$(this).find("a").target = "_blank";
window.location= $(this).find("a").attr("href")

What error message are you getting?

I'd guess your actual error is because your php variable isn't wrapped in quotes. Try this

$update_query = "UPDATE db.tablename SET insert_time=now() WHERE username='" .$somename . "'"; 

Maximum time between connection request and a timeout error. When the client tries to make a connection, if the timeout wait limit is reached, it will stop trying and raise an error.

Generally you should use String.Format because it's relatively fast and it supports globalization (assuming you're actually trying to write something that is read by the user). It also makes it easier to globalize if you're trying to translate one string versus 3 or more per statement (especially for languages that have drastically different grammatical structures).

Now if you never plan on translating anything, then either rely on Java's built in conversion of + operators into StringBuilder. Or use Java's StringBuilder explicitly.

It means somewhere in your chain of calls, you tried to access a Property or call a method on an object that was null.

Given your statement:

img1.ImageUrl = ConfigurationManager
                    .AppSettings
                    .Get("Url")
                    .Replace("###", randomString) 
                + Server.UrlEncode(
                      ((System.Web.UI.MobileControls.Form)Page
                      .FindControl("mobileForm"))
                      .Title);

I'm guessing either the call to AppSettings.Get("Url") is returning null because the value isn't found or the call to Page.FindControl("mobileForm") is returning null because the control isn't found.

You could easily break this out into multiple statements to solve the problem:

var configUrl = ConfigurationManager.AppSettings.Get("Url");
var mobileFormControl = Page.FindControl("mobileForm")
                            as System.Web.UI.MobileControls.Form;

if(configUrl != null && mobileFormControl != null)
{
    img1.ImageUrl = configUrl.Replace("###", randomString) + mobileControl.Title;
}

In many cases an element must be positioned for z-index to work.

Indeed, applying position: relative to the elements in the question would likely solve the problem (but there's not enough code provided to know for sure).

Actually, position: fixed, position: absolute and position: sticky will also enable z-index, but those values also change the layout. With position: relative the layout isn't disturbed.

Essentially, as long as the element isn't position: static (the default setting) it is considered positioned and z-index will work.

Many answers to "Why isn't z-index working?" questions assert that z-index only works on positioned elements. As of CSS3, this is no longer true.

Elements that are flex items or grid items can use z-index even when position is static.

From the specs:

4.3. Flex Item Z-Ordering

Flex items paint exactly the same as inline blocks, except that order-modified document order is used in place of raw document order, and z-index values other than auto create a stacking context even if position is static.

5.4. Z-axis Ordering: the z-index property

The painting order of grid items is exactly the same as inline blocks, except that order-modified document order is used in place of raw document order, and z-index values other than auto create a stacking context even if position is static.

Here's a demonstration of z-index working on non-positioned flex items: https://jsfiddle.net/m0wddwxs/

JSON.stringify(j, null, 4) would give you beautified JSON in case you need beautification also

The second parameter is replacer. It can be used as Filter where you can filter out certain key values when stringifying. If set to null it will return all key value pairs

If your object could contain any key/value pairs, you could declare an interface called keyable like :

interface keyable {
    [key: string]: any  
}

then use it as follows :

let countryProviders: keyable[];

or

let countryProviders: Array<keyable>;

This question is really multiple questions in one. They are different ways of styling something. Here are links to the questions within this question:

• font-family of an <option> element:
  • Question: How to apply font family in HTML tag of select option
• font-size of an <option> element:
  • Question: How do I change the font-size of an <option> element within <select>?
• background-color of an <option> element:
  • Question: How can I set the background color of <option> in a <select> element?
• font-weight of an <option> element:
  • Question: HTML font weight property on OPTION of HTML SELECT
• color of an <option> element:
  • Question: How do change the color of the text of an <option> within a <select>?

If you know the structure of the json that you're receiving then I'd suggest having a class structure that mirrors what you're receiving in json.

Then you can call its something like this...

AddressMap addressMap = JsonConvert.DeserializeObject<AddressMap>(json);

(Where json is a string containing the json in question)

If you don't know the format of the json you've receiving then it gets a bit more complicated and you'd probably need to manually parse it.

The simpler and current approach for adding header to a single request is:

// Step 1

const yourHeader: HttpHeaders = new HttpHeaders({
    Authorization: 'Bearer JWT-token'
});

// POST request

this.http.post(url, body, { headers: yourHeader });

// GET request

this.http.get(url, { headers: yourHeader });

In a word - yes. Actually, many classes in the JDK implement multiple interfaces. E.g., ArrayList implements List, RandomAccess, Cloneable, and Serializable.

Just want to add one more way. Found it elsewhere, and is quite simple. Say I want to pass yes for all the prompts at command line for a command "execute_command", Then I would simply pipe yes to it.

yes | execute_command

This will use yes as the answer to all yes/no prompts.

You can just do it like this:

#content {
    position: relative;
}
#content img {
    position: absolute;
    top: 0px;
    right: 0px;
}

<div id="content">
    <img src="images/ribbon.png" class="ribbon"/>
    <div>some text...</div>
</div>

You need to look at upgrading your OS and Java. Java 5.0 is EOL but if you cannot update to Java 6, you could use the latest patch level 22!

32-bit Windows is limited to ~ 1.3 GB so you are doing well to se the maximum to 1.8. Note: this is a problem with continous memory, and as your system runs its memory space can get fragmented so it does not suprise me you have this problem.

A 64-bit OS, doesn't have this problem as it has much more virtual space, you don't even have to upgrade to a 64-bit version of java to take advantage of this.

BTW, in my experience, 32-bit Java 5.0 can be faster than 64-bit Java 5.0. It wasn't until many years later that Java 6 update 10 was faster for 64-bit.

One requirement for remote debugging is that the windows account used to run SSMS be part of the sysadmin role. See this MSDN link: http://msdn.microsoft.com/en-us/library/cc646024%28v=sql.105%29.aspx

You need to install it in a directory in your home folder, and somehow manipulate the PYTHONPATH so that directory is included.

The best and easiest is to use virtualenv. But that requires installation, causing a catch 22. :) But check if virtualenv is installed. If it is installed you can do this:

$ cd /tmp
$ virtualenv foo
$ cd foo
$ ./bin/python

Then you can just run the installation as usual, with /tmp/foo/python setup.py install. (Obviously you need to make the virtual environment in your a folder in your home directory, not in /tmp/foo. ;) )

If there is no virtualenv, you can install your own local Python. But that may not be allowed either. Then you can install the package in a local directory for packages:

$ wget http://pypi.python.org/packages/source/s/six/six-1.0b1.tar.gz#md5=cbfcc64af1f27162a6a6b5510e262c9d
$ tar xvf six-1.0b1.tar.gz 
$ cd six-1.0b1/
$ pythonX.X setup.py   install --install-dir=/tmp/frotz

Now you need to add /tmp/frotz/pythonX.X/site-packages to your PYTHONPATH, and you should be up and running!

Here is what I did.

My solution to this problem encountered using ASP.NET Core 2.0 and EF Core 2.0 was to perform the following in order:

1. Run update-database command in Package Management Console (PMC) to create the database (this results in the "Introducing FOREIGN KEY constraint ... may cause cycles or multiple cascade paths." error)

2. Run script-migration -Idempotent command in PMC to create a script that can be run regardless of the existing tables/constraints

3. Take the resulting script and find ON DELETE CASCADE and replace with ON DELETE NO ACTION

4. Execute the modified SQL against the database

Now, your migrations should be up-to-date and the cascading deletes should not occur.

Too bad I was not able to find any way to do this in Entity Framework Core 2.0.

Good luck!

one approach is to fill an array via LINQ

if you want to fill an array with one element you can simply write

string[] arrayToBeFilled;
arrayToBeFilled= arrayToBeFilled.Append("str").ToArray();

furthermore, If you want to fill an array with multiple elements you can use the previous code in a loop

//the array you want to fill values in
string[] arrayToBeFilled;
//list of values that you want to fill inside an array
List<string> listToFill = new List<string> { "a1", "a2", "a3" };
//looping through list to start filling the array

foreach (string str in listToFill){
// here are the LINQ extensions
arrayToBeFilled= arrayToBeFilled.Append(str).ToArray();
}

Have in mind that clone() doesn't work out of the box. You will have to implement Cloneable and override the clone() method making in public.

There are a few alternatives, which are preferable (since the clone() method has lots of design issues, as stated in other answers), and the copy-constructor would require manual work:

• BeanUtils.cloneBean(original) creates a shallow clone, like the one created by Object.clone(). (this class is from commons-beanutils)

• SerializationUtils.clone(original) creates a deep clone. (i.e. the whole properties graph is cloned, not only the first level) (from commons-lang), but all classes must implement Serializable

• Java Deep Cloning Library offers deep cloning without the need to implement Serializable

import * as utils from './utils.js'; 

If you do the above, you will be able to use functions in utils.js as

utils.someFunction()

This works for me, with Mac OS Sierra using Python,

options = webdriver.ChromeOptions()
options.add_argument("--kiosk")
driver = webdriver.Chrome(chrome_options=options)

To manage non-integer inputs:

number = raw_input()
try:
    value = int(number)
except ValueError:
    value = 0
