When retrying due to error, you should always:

• implement a retry limit, or you may get blocked on an infinite loop
• implement a delay, or you'll hammer resources too hard, such as your CPU or the already distressed remote server

A simple generic way to solve this problem while covering those concerns would be to use the backoff library. A basic example:

import backoff

@backoff.on_exception(
    backoff.expo,
    MyException,
    max_tries=5
)
def make_request(self, data):
    # do the request

This code wraps make_request with a decorator which implements the retry logic. We retry whenever our specific error MyException occurs, with a limit of 5 retries. Exponential backoff is a good idea in this context to help minimize the additional burden our retries place on the remote server.

Use this:

listBox1.Items.Clear();

FYI, you can also use map.keySet() and map.values() if you're only interested in keys/values of the map and not the other.

Recently, I have seen this problem too. Below, you have my solution:

1. ping github.com, if ping failed. it is DNS error.
2. sudo vim /etc/resolv.conf, the add: nameserver 8.8.8.8 nameserver 8.8.4.4

Or it can be a genuine network issue. Restart your network-manager using sudo service network-manager restart or fix it up

I have just received this error after switching from HTTPS to SSH (for my origin remote). To fix, I simply ran the following command (for each repo):

ssh -T [email protected]

Upon receiving a successful response, I could fetch/push to the repo with ssh.

I took that command from Git's Testing your SSH connection guide, which is part of the greater Connecting to GitHub with with SSH guide.

Since the accepted answer and also the next highest voted answer have, in my opinion, some problems, I'd like to offer one more answer that is based closely on Ihor B.'s answer with some small but important modifications.

This solution allows you to run profiling on either by wrapping a function call with the profile function and calling it, or by decorating your function/method with the @profile decorator.

The first technique is useful when you want to profile some third-party code without messing with its source, whereas the second technique is a bit "cleaner" and works better when you are don't mind modifying the source of the function/method you want to profile.

I've also modified the output, so that you get RSS, VMS, and shared memory. I don't care much about the "before" and "after" values, but only the delta, so I removed those (if you're comparing to Ihor B.'s answer).

Profiling code

# profile.py
import time
import os
import psutil
import inspect


def elapsed_since(start):
    #return time.strftime("%H:%M:%S", time.gmtime(time.time() - start))
    elapsed = time.time() - start
    if elapsed < 1:
        return str(round(elapsed*1000,2)) + "ms"
    if elapsed < 60:
        return str(round(elapsed, 2)) + "s"
    if elapsed < 3600:
        return str(round(elapsed/60, 2)) + "min"
    else:
        return str(round(elapsed / 3600, 2)) + "hrs"


def get_process_memory():
    process = psutil.Process(os.getpid())
    mi = process.memory_info()
    return mi.rss, mi.vms, mi.shared

    if abs(bytes) < 1000:
        return str(bytes)+"B"
    elif abs(bytes) < 1e6:
        return str(round(bytes/1e3,2)) + "kB"
    elif abs(bytes) < 1e9:
        return str(round(bytes / 1e6, 2)) + "MB"
    else:
        return str(round(bytes / 1e9, 2)) + "GB"


def profile(func, *args, **kwargs):
    def wrapper(*args, **kwargs):
        rss_before, vms_before, shared_before = get_process_memory()
        start = time.time()
        result = func(*args, **kwargs)
        elapsed_time = elapsed_since(start)
        rss_after, vms_after, shared_after = get_process_memory()
        print("Profiling: {:>20}  RSS: {:>8} | VMS: {:>8} | SHR {"
              ":>8} | time: {:>8}"
            .format("<" + func.__name__ + ">",
                    format_bytes(rss_after - rss_before),
                    format_bytes(vms_after - vms_before),
                    format_bytes(shared_after - shared_before),
                    elapsed_time))
        return result
    if inspect.isfunction(func):
        return wrapper
    elif inspect.ismethod(func):
        return wrapper(*args,**kwargs)

Example usage, assuming the above code is saved as profile.py:

from profile import profile
from time import sleep
from sklearn import datasets # Just an example of 3rd party function call


# Method 1
run_profiling = profile(datasets.load_digits)
data = run_profiling()

# Method 2
@profile
def my_function():
    # do some stuff
    a_list = []
    for i in range(1,100000):
        a_list.append(i)
    return a_list


res = my_function()

This should result in output similar to the below:

Profiling:        <load_digits>  RSS:   5.07MB | VMS:   4.91MB | SHR  73.73kB | time:  89.99ms
Profiling:        <my_function>  RSS:   1.06MB | VMS:   1.35MB | SHR       0B | time:   8.43ms

A couple of important final notes:

1. Keep in mind, this method of profiling is only going to be approximate, since lots of other stuff might be happening on the machine. Due to garbage collection and other factors, the deltas might even be zero.
2. For some unknown reason, very short function calls (e.g. 1 or 2 ms) show up with zero memory usage. I suspect this is some limitation of the hardware/OS (tested on basic laptop with Linux) on how often memory statistics are updated.
3. To keep the examples simple, I didn't use any function arguments, but they should work as one would expect, i.e. profile(my_function, arg) to profile my_function(arg)

 @Html.TextBox("Receivers", Model, new { @class = "form-control", style = "width: 300px", @readonly = "readonly" })

var a = [1,2,3], b = [4,1,5,2];

b.forEach(function(value){
  if (a.indexOf(value)==-1) a.push(value);
});

console.log(a);
// [1, 2, 3, 4, 5]

For more details read up on Array.indexOf.

If you want to rely on jQuery, instead use jQuery.inArray:

$.each(b,function(value){
  if ($.inArray(value,a)==-1) a.push(value);
});

If all your values are simply and uniquely representable as strings, however, you should use an Object instead of an Array, for a potentially massive speed increase (as described in the answer by @JonathanSampson).

Using day.js

In browser:

dayjs.extend(dayjs_plugin_utc)
console.log(dayjs.utc().unix())

<script src="https://cdn.jsdelivr.net/npm/dayjs@latest/dayjs.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/dayjs@latest/plugin/utc.js"></script>

In node.js:

import dayjs from 'dayjs'
dayjs.extend(require('dayjs/plugin/utc'))
console.log(dayjs.utc().unix())

You get a UTC unix timestamp without milliseconds.

var idList=new int[]{1, 2, 3, 4};
var friendsToUpdate = await Context.Friends.Where(f => 
    idList.Contains(f.Id).ToListAsync();

foreach(var item in previousEReceipts)
{
  item.msgSentBy = "1234";
}

You can use foreach to update each element that meets your condition.

Here is an example in a more generic way:

var itemsToUpdate = await Context.friends.Where(f => f.Id == <someCondition>).ToListAsync();

foreach(var item in itemsToUpdate)
{
   item.property = updatedValue;
}
Context.SaveChanges()

In general you will most probably use async methods with await for db queries.

What I did when I wanted to draw a dotted line is to define a drawable dash_line.xml:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" 
    android:shape="line" >
<stroke
    android:dashGap="3dp"
    android:dashWidth="2dp"
    android:width="1dp"
    android:color="@color/black" />
</shape>

And then in the layout just define a view with background as dash_line. Note to include android:layerType="software", otherwise it won't work.

<View
            android:layout_width="match_parent"
            android:layout_height="5dp"
            android:background="@drawable/dash_line"
            android:layerType="software" />

You should not rely on [NSDate date] for timing purposes since it can over- or under-report the elapsed time. There are even cases where your computer will seemingly time-travel since the elapsed time will be negative! (E.g. if the clock moved backwards during timing.)

According to Aria Haghighi in the "Advanced iOS Gesture Recognition" lecture of the Winter 2013 Stanford iOS course (34:00), you should use CACurrentMediaTime() if you need an accurate time interval.

Objective-C:

#import <QuartzCore/QuartzCore.h>

CFTimeInterval startTime = CACurrentMediaTime();
// perform some action
CFTimeInterval elapsedTime = CACurrentMediaTime() - startTime;

Swift:

let startTime = CACurrentMediaTime()
// perform some action
let elapsedTime = CACurrentMediaTime() - startTime

The reason is that [NSDate date] syncs on the server, so it could lead to "time-sync hiccups" which can lead to very difficult-to-track bugs. CACurrentMediaTime(), on the other hand, is a device time that doesn't change with these network syncs.

You will need to add the QuartzCore framework to your target's settings.

Adding to above answer if we want to format Double multiple times, we can use protocol extension of Double like below:

extension Double {
    var dollarString:String {
        return String(format: "$%.2f", self)
    }
}

let a = 45.666

print(a.dollarString) //will print "$45.67"

Something like this:

import matplotlib.pyplot as plt
... code for plot 1 ...
plt.show()
... code for plot 2...
plt.show()

Note that this will also work if you are using the seaborn package for plotting:

import matplotlib.pyplot as plt
import seaborn as sns
sns.barplot(... code for plot 1 ...) # plot 1
plt.show()
sns.barplot(... code for plot 2 ...) # plot 2
plt.show()

hibernate3.HibernateQueryException: Books is not mapped [SELECT COUNT(*) FROM Books];

Hibernate is trying to say that it does not know an entity named "Books". Let's look at your entity:

@javax.persistence.Entity
@javax.persistence.Table(name = "Books")
public class Book {

Right. The table name for Book has been renamed to "Books" but the entity name is still "Book" from the class name. If you want to set the entity name, you should use the @Entity annotation's name instead:

// this allows you to use the entity Books in HQL queries
@javax.persistence.Entity(name = "Books")
public class Book {

That sets both the entity name and the table name.

The opposite problem happened to me when I was migrating from the Person.hbm.xml file to using the Java annotations to describe the hibernate fields. My old XML file had:

<hibernate-mapping package="...">
    <class name="Person" table="persons" lazy="true">
       ...
</hibernate-mapping>

And my new entity had a @Entity(name=...) which I needed to set the name of the table.

// this renames the entity and sets the table name
@javax.persistence.Entity(name = "persons")
public class Person {
    ...

What I then was seeing was HQL errors like:

QuerySyntaxException: Person is not mapped
     [SELECT id FROM Person WHERE id in (:ids)]

The problem with this was that the entity name was being renamed to persons as well. I should have set the table name using:

// no name = here so the entity can be used as Person
@javax.persistence.Entity
// table name specified here
@javax.persistence.Table(name = "persons")
public class Person extends BaseGeneratedId {

Hope this helps others.

Try this:

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.12.1</version>
</dependency>

You can synchronize your code over the class. That would be simplest.

   public class Test  
    {  
       private static int count = 0;  
       private static final Object lock= new Object();    
       public synchronized void foo() 
      {  
          synchronized(Test.class)
         {  
             count++;  
         }  
      }  
    }

Hope you find this answer useful.

This might come a little late...

I wrote this KalmanLocationManager for Android, which wraps the two most common location providers, Network and GPS, kalman-filters the data, and delivers updates to a LocationListener (like the two 'real' providers).

I use it mostly to "interpolate" between readings - to receive updates (position predictions) every 100 millis for instance (instead of the maximum gps rate of one second), which gives me a better frame rate when animating my position.

Actually, it uses three kalman filters, on for each dimension: latitude, longitude and altitude. They're independent, anyway.

This makes the matrix math much easier: instead of using one 6x6 state transition matrix, I use 3 different 2x2 matrices. Actually in the code, I don't use matrices at all. Solved all equations and all values are primitives (double).

The source code is working, and there's a demo activity. Sorry for the lack of javadoc in some places, I'll catch up.

The first answer is definitely the correct answer and is what I based this lambda version off of, which is much shorter in syntax. Since Runnable has only 1 override method "run()", we can use a lambda:

this.m_someBoolFlag = false;
new android.os.Handler().postDelayed(() -> this.m_someBoolFlag = true, 300);

size_t is the size of a pointer.

So in 32 bits or the common ILP32 (integer, long, pointer) model size_t is 32 bits. and in 64 bits or the common LP64 (long, pointer) model size_t is 64 bits (integers are still 32 bits).

There are other models but these are the ones that g++ use (at least by default)

_mytexteditingcontroller.value = new TextEditingController.fromValue(new TextEditingValue(text: "My String")).value;

This seems to work if anyone has a better way please feel free to let me know.

Other way is with:

np.vectorize(lambda x: 6 <= x <= 10)(a)

which returns:

array([False, False, False,  True,  True,  True, False, False, False])

It is sometimes useful for masking time series, vectors, etc.

I faced the same error, upon checking I had a developer access and couldn't publish a new branch. Adding higher access rights resolved this issue.(Gitlab)

There are several ways to intercept the initialization process in Spring. If you have to initialize all beans and autowire/inject them there are at least two ways that I know of that will ensure this. I have only testet the second one but I belive both work the same.

If you are using @Bean you can reference by initMethod, like this.

@Configuration
public class BeanConfiguration {

  @Bean(initMethod="init")
  public BeanA beanA() {
    return new BeanA();
  }
}

public class BeanA {

  // method to be initialized after context is ready
  public void init() {
  }

} 

If you are using @Component you can annotate with @EventListener like this.

@Component
public class BeanB {

  @EventListener
  public void onApplicationEvent(ContextRefreshedEvent event) {
  }
}

In my case I have a legacy system where I am now taking use of IoC/DI where Spring Boot is the choosen framework. The old system brings many circular dependencies to the table and I therefore must use setter-dependency a lot. That gave me some headaches since I could not trust @PostConstruct since autowiring/injection by setter was not yet done. The order is constructor, @PostConstruct then autowired setters. I solved it with @EventListener annotation which wil run last and at the "same" time for all beans. The example shows implementation of InitializingBean aswell.

I have two classes (@Component) with dependency to each other. The classes looks the same for the purpose of this example displaying only one of them.

@Component
public class BeanA implements InitializingBean {
  private BeanB beanB;

  public BeanA() {
    log.debug("Created...");
  }

  @PostConstruct
  private void postConstruct() {
    log.debug("@PostConstruct");
  }

  @Autowired
  public void setBeanB(BeanB beanB) {
    log.debug("@Autowired beanB");
    this.beanB = beanB;
  }

  @Override
  public void afterPropertiesSet() throws Exception {
    log.debug("afterPropertiesSet()");
  }

  @EventListener
  public void onApplicationEvent(ContextRefreshedEvent event) {
    log.debug("@EventListener");
  } 
}

This is the log output showing the order of the calls when the container starts.

As you can see @EventListener is run last after everything is ready and configured.

If the string contains UTF-8 characters outside of the ASCII range, then boost::algorithm::to_lower will not convert those. Better use boost::locale::to_lower when UTF-8 is involved. See http://www.boost.org/doc/libs/1_51_0/libs/locale/doc/html/conversions.html

My cacerts file was totally empty. I solved this by copying the cacerts file off my windows machine (that's using Oracle Java 7) and scp'd it to my Linux box (OpenJDK).

cd %JAVA_HOME%/jre/lib/security/
scp cacerts mylinuxmachin:/tmp

and then on the linux machine

cp /tmp/cacerts /etc/ssl/certs/java/cacerts

It's worked great so far.

Either create an auto-increment id or a UNIQUE id and add it to the natural key you are talking about with the 4 fields. this will make every row in the table unique...

If you don't want to use RegEx (which seems highly unnecessary given your problem), perhaps you should try something like this:

public String modified(final String input){
    final StringBuilder builder = new StringBuilder();
    for(final char c : input.toCharArray())
        if(Character.isLetterOrDigit(c))
            builder.append(Character.isLowerCase(c) ? c : Character.toLowerCase(c));
    return builder.toString();
}

It loops through the underlying char[] in the String and only appends the char if it is a letter or digit (filtering out all symbols, which I am assuming is what you are trying to accomplish) and then appends the lower case version of the char.

I know it's late, but i hope someone will be helped of this answer

DATE() is a MySQL function that extracts only the date part of a date or date/time expression

simplexml_load_file() interprets an XML file (either a file on your disk or a URL) into an object. What you have in $feed is a string.

You have two options:

• Use file_get_contents() to get the XML feed as a string, and use e simplexml_load_string():

  $feed = file_get_contents('...');
  $items = simplexml_load_string($feed);
  

• Load the XML feed directly using simplexml_load_file():

  $items = simplexml_load_file('...');
  

In your package.json in the "dependencies" section add moment:

"dependencies": {

}

In the component where you would like to use moment, import it:

import moment from 'moment'
...

And in the same component add a computed property:

computed: {
  timestamp: function () {
    return moment(this.<model>.attributes['created-at']).format('YYYY-MM-DD [at] hh:mm')
  }
}

And then in the template of this component:

I like Consolas a lot. This top-10 list is a good resource for others. It includes examples and descriptions.

Firstly, you'll need more than just -moz-border-radius if you want to support all browsers. You should specify all variants, including plain border-radius, as follows:

-moz-border-radius: 5px;
-webkit-border-radius: 5px;
border-radius: 5px;

Secondly, to directly answer your question, border-radius doesn't actually display a border; it just sets how the corners look of the border, if there is one.

To turn on the border, and thus get your rounded corners, you also need the border attribute on your td and th elements.

td, th {
   border:solid black 1px;
}

You will also see the rounded corners if you have a background colour (or graphic), although of course it would need to be a different background colour to the surrounding element in order for the rounded corners to be visible without a border.

It's worth noting that some older browsers don't like putting border-radius on tables/table cells. It may be worth putting a <div> inside each cell and styling that instead. However this shouldn't affect current versions of any browsers (except IE, that doesn't support rounded corners at all - see below)

Finally, not that IE doesn't support border-radius at all (IE9 beta does, but most IE users will be on IE8 or less). If you want to hack IE to support border-radius, look at http://css3pie.com/

[EDIT]

Okay, this was bugging me, so I've done some testing.

Here's a JSFiddle example I've been playing with

It seems like the critical thing you were missing was border-collapse:separate; on the table element. This stops the cells from linking their borders together, which allows them to pick up the border radius.

Hope that helps.

If you download Java Development Kit(JDK) then there is a difference as it contains native libraries which differ for different architectures:

• x86 is for 32-bit OS
• x64 is for 64-bit OS

In addition you can use 32-bit JDK(x86) on 64-bit OS. But you can not use 64-bit JDK on 32-bit OS.

At the same time you can run compiled Java classes on any JVM. It does not matter whether it 32 or 64-bit.

In case of WSS 3.0 recently I experienced same issue. It was because of column that was accessed from code was not present in the wss list.

As an extension of @Demyn's answer, I created some utility functions which print the current function's name and current function's arguments:

import inspect
import logging
import traceback

def get_function_name():
    return traceback.extract_stack(None, 2)[0][2]

def get_function_parameters_and_values():
    frame = inspect.currentframe().f_back
    args, _, _, values = inspect.getargvalues(frame)
    return ([(i, values[i]) for i in args])

def my_func(a, b, c=None):
    logging.info('Running ' + get_function_name() + '(' + str(get_function_parameters_and_values()) +')')
    pass

logger = logging.getLogger()
handler = logging.StreamHandler()
formatter = logging.Formatter(
    '%(asctime)s [%(levelname)s] -> %(message)s')
handler.setFormatter(formatter)
logger.addHandler(handler)
logger.setLevel(logging.INFO)

my_func(1, 3) # 2016-03-25 17:16:06,927 [INFO] -> Running my_func([('a', 1), ('b', 3), ('c', None)])

After looking on the accepted answer I realized that if know size of required vector then we have to use a loop to initialize every element

But I found new to do this using default_structure_element like following...

#include <bits/stdc++.h>
typedef long long ll;
using namespace std;

typedef struct subject {
  string name;
  int marks;
  int credits;
}subject;

int main(){
  subject default_subject;
  default_subject.name="NONE";
  default_subject.marks = 0;
  default_subject.credits = 0;

  vector <subject> sub(10,default_subject);         // default_subject to initialize

  //to check is it initialised
  for(ll i=0;i<sub.size();i++) {
    cout << sub[i].name << " " << sub[i].marks << " " << sub[i].credits << endl;
  } 
}

Then I think its good to way to initialize a vector of the struct, isn't it?

Try

if (!(i == 'InvKey' || i == 'PostDate')) {

or

if (i != 'InvKey' || i != 'PostDate') {

that says if i does not equals InvKey OR PostDate

drop database <db_name>;
FLUSH PRIVILEGES;

In VirtualBox you should add custom resolution via the command:

VBoxManage setextradata "VM name" "CustomVideoMode1" "800x480x16"

instead of editing a .vbox file.

This solution works fine for me!

You just need to use below code when launching the new activity.

startActivity(new Intent(this, newactivity.class));
finish();

C# in .NET 3.5 using System.DirectoryServices.AccountManagement.

 bool valid = false;
 using (PrincipalContext context = new PrincipalContext(ContextType.Domain))
 {
     valid = context.ValidateCredentials( username, password );
 }

This will validate against the current domain. Check out the parameterized PrincipalContext constructor for other options.

On the left in the logcat view you have the "Saved Filters" windows. Here you can add a new logcat filter by Application Name (for example, com.your.package)

Here is a way that addresses a few issues:

1. Alignment issues after content is updated, especially if the placement is "top". The key is calling ._popper.update(), which recalculates the position of the popover.
2. Width change after the content is updated. It doesn't break anything, it just looks jarring to the user. To lessen that, I set the width of the popover to 100% (which is then capped by the max-width).

var e = $("#whatever");
e.popover({
    placement: "top",
    trigger: "hover",
    title: "Test Popover",
    content: "<span class='content'>Loading...</span>",
    html: true
}).on("inserted.bs.popover", function() {
    var popover = e.data('bs.popover');
    var tip = $(popover.tip);
    tip.css("width", "100%");
    $.ajax("/whatever")
        .done(function(data) {
            tip.find(".content").text(data);
            popover._popper.update();
        }).fail(function() {
            tip.find(".content").text("Sorry, something went wrong");
        });
});

RMDIR path_to_folder /S

ex. RMDIR "C:\tmp" /S

Note that you'll be prompted if you're really going to delete the "C:\tmp" folder. Combining it with /Q switch will remove the folder silently (ex. RMDIR "C:\tmp" /S /Q)

We can use CASE for setting blank value to some char or String. I am using NA as Default string.

SELECT phone,   
CASE WHEN phone2 = '' THEN 'NA' END AS phone2 ELSE ISNULL(phone2,0) 
FROM jewishyellow.users  WHERE phone LIKE '813%'

There is also a built-in function for this task:

variable = lines( itab_name ).

Just like the "pure" ABAP syntax described by IronGoofy, the function "lines( )" writes the number of lines of table itab_name into the variable.

app.get('/fruit/:fruitName/:fruitColor', function(req, res) {
    var data = {
        "fruit": {
            "apple": req.params.fruitName,
            "color": req.params.fruitColor
        }
    }; 

    send.json(data);
});

If that doesn't work, try using console.log(req.params) to see what it is giving you.

The essential idea here is to select the data you want to sum, and then sum them. This selection of data can be done in several different ways, a few of which are shown below.

Boolean indexing

Arguably the most common way to select the values is to use Boolean indexing.

With this method, you find out where column 'a' is equal to 1 and then sum the corresponding rows of column 'b'. You can use loc to handle the indexing of rows and columns:

>>> df.loc[df['a'] == 1, 'b'].sum()
15

The Boolean indexing can be extended to other columns. For example if df also contained a column 'c' and we wanted to sum the rows in 'b' where 'a' was 1 and 'c' was 2, we'd write:

df.loc[(df['a'] == 1) & (df['c'] == 2), 'b'].sum()

Query

Another way to select the data is to use query to filter the rows you're interested in, select column 'b' and then sum:

>>> df.query("a == 1")['b'].sum()
15

Again, the method can be extended to make more complicated selections of the data:

df.query("a == 1 and c == 2")['b'].sum()

Note this is a little more concise than the Boolean indexing approach.

Groupby

The alternative approach is to use groupby to split the DataFrame into parts according to the value in column 'a'. You can then sum each part and pull out the value that the 1s added up to:

>>> df.groupby('a')['b'].sum()[1]
15

This approach is likely to be slower than using Boolean indexing, but it is useful if you want check the sums for other values in column a:

>>> df.groupby('a')['b'].sum()
a
1    15
2     8

If you need this, you shouldn't use forEach, but one of the other methods available on streams; which one, depends on what your goal is.

For example, if the goal of this loop is to find the first element which matches some predicate:

Optional<SomeObject> result =
    someObjects.stream().filter(obj -> some_condition_met).findFirst();

(Note: This will not iterate the whole collection, because streams are lazily evaluated - it will stop at the first object that matches the condition).

If you just want to know if there's an element in the collection for which the condition is true, you could use anyMatch:

boolean result = someObjects.stream().anyMatch(obj -> some_condition_met);

You can use nonHistorySelectors option from jquery mobile where you do not want to track history. You can find the detailed documentation here http://jquerymobile.com/demos/1.0a4.1/#docs/api/globalconfig.html

// thousand separates a digit-only string using commas
// by element:  onkeyup = "ThousandSeparate(this)"
// by ID:       onkeyup = "ThousandSeparate('txt1','lbl1')"
function ThousandSeparate()
{
    if (arguments.length == 1)
    {
        var V = arguments[0].value;
        V = V.replace(/,/g,'');
        var R = new RegExp('(-?[0-9]+)([0-9]{3})'); 
        while(R.test(V))
        {
            V = V.replace(R, '$1,$2');
        }
        arguments[0].value = V;
    }
    else  if ( arguments.length == 2)
    {
        var V = document.getElementById(arguments[0]).value;
        var R = new RegExp('(-?[0-9]+)([0-9]{3})'); 
        while(R.test(V))
        {
            V = V.replace(R, '$1,$2');
        }
        document.getElementById(arguments[1]).innerHTML = V;
    }
    else return false;
}   

Try this. Note there's no database specified - it just runs "on the server"

psql -U postgres -c "drop database databasename"

If that doesn't work, I have seen a problem with postgres holding onto orphaned prepared statements.
To clean them up, do this:

SELECT * FROM pg_prepared_xacts;

then for every id you see, run this:

ROLLBACK PREPARED '<id>';

Here is a class providing a cancel method for a delayed action

public class DelayedAction {

private Handler _handler;
private Runnable _runnable;

/**
 * Constructor
 * @param runnable The runnable
 * @param delay The delay (in milli sec) to wait before running the runnable
 */
public DelayedAction(Runnable runnable, long delay) {
    _handler = new Handler(Looper.getMainLooper());
    _runnable = runnable;
    _handler.postDelayed(_runnable, delay);
}

/**
 * Cancel a runnable
 */
public void cancel() {
    if ( _handler == null || _runnable == null ) {
        return;
    }
    _handler.removeCallbacks(_runnable);
}}

You can use clone, and then since each div has a class of car_well you can use insertAfter to insert after the last div.

$("#car2").clone().insertAfter("div.car_well:last");

Usually a back-reference is either $1 or \1 (backslash one) for the first capture group (the first match of a pattern in parentheses), and indeed Sublime supports both syntaxes. So try:

my name used to be \1

or

my name used to be $1

Also note that your original capture pattern:

my name is (\w)+

is incorrect and will only capture the final letter of the name rather than the whole name. You should use the following pattern to capture all of the letters of the name:

my name is (\w+)

Swift version

Only trims spaces at the end of the String:

private func removingSpacesAtTheEndOfAString(var str: String) -> String {
    var i: Int = countElements(str) - 1, j: Int = i

    while(i >= 0 && str[advance(str.startIndex, i)] == " ") {
        --i
    }

    return str.substringWithRange(Range<String.Index>(start: str.startIndex, end: advance(str.endIndex, -(j - i))))
}

Trims spaces on both sides of the String:

var str: String = " Yolo "
var trimmedStr: String = str.stringByTrimmingCharactersInSet(NSCharacterSet.whitespaceCharacterSet())

Ahh, found the answer myself:

if (/[a-zA-Z]/.test(num)) {
  alert('Letter Found')
}

The purpose of ForeignKey is to prevent the creation of data if the field value does not match its ForeignKey. To accomplish this in MongoDB, we use Schema middlewares that ensure the data consistency.

Please have a look at the documentation. https://mongoosejs.com/docs/middleware.html#pre

You need System.Diagnostics.Process.Start().

The simplest example:

Process.Start("notepad.exe", fileName);

More Generic Approach:

Process.Start(fileName);

The second approach is probably a better practice as this will cause the windows Shell to open up your file with it's associated editor. Additionally, if the file specified does not have an association, it'll use the Open With... dialog from windows.

Note to those in the comments, thankyou for your input. My quick n' dirty answer was slightly off, i've updated the answer to reflect the correct way.

Here is some example code I've found... does anyone have a better way?

  function include(url)
  {
    var s = document.createElement("script");
    s.setAttribute("type", "text/javascript");
    s.setAttribute("src", url);
    var nodes = document.getElementsByTagName("*");
    var node = nodes[nodes.length -1].parentNode;
    node.appendChild(s);
  }

For Python 2.x, use python's hashlib

import hashlib
m = hashlib.md5()
m.update("000005fab4534d05api_key9a0554259914a86fb9e7eb014e4e5d52permswrite")
print m.hexdigest()

Output: a02506b31c1cd46c2e0b6380fb94eb3d

You can execute it just as you select a table using SELECT clause. In addition you can provide parameters within parentheses.

Try with below syntax:

SELECT * FROM yourFunctionName(parameter1, parameter2)

For Angular Version 11+

Configuration

The styles and scripts options in your angular.json configuration now allow to reference a package directly:

before: "styles": ["../node_modules/bootstrap/dist/css/bootstrap.css"]
after: "styles": ["bootstrap/dist/css/bootstrap.css"]

          "builder": "@angular-devkit/build-angular:browser",
          "options": {
            "outputPath": "dist/ng6",
            "index": "src/index.html",
            "main": "src/main.ts",
            "polyfills": "src/polyfills.ts",
            "tsConfig": "src/tsconfig.app.json",
            "assets": [
              "src/favicon.ico",
              "src/assets"
            ],
            "styles": [
              "src/styles.css","bootstrap/dist/css/bootstrap.min.css"

            ],
            "scripts": [
                       "jquery/dist/jquery.min.js",
                       "bootstrap/dist/js/bootstrap.min.js"
                       ]
          },

Angular Version 10 and below

Angular v6 Onwards

CLI projects in angular 6 onwards will be using angular.json instead of .angular-cli.json for build and project configuration.

Each CLI workspace has projects, each project has targets, and each target can have configurations.Docs

. {
  "projects": {
    "my-project-name": {
      "projectType": "application",
      "architect": {
        "build": {
          "configurations": {
            "production": {},
            "demo": {},
            "staging": {},
          }
        },
        "serve": {},
        "extract-i18n": {},
        "test": {},
      }
    },
    "my-project-name-e2e": {}
  },
}

OPTION-1
execute npm install bootstrap@4 jquery --save
The JavaScript parts of Bootstrap are dependent on jQuery. So you need the jQuery JavaScript library file too.

In your angular.json add the file paths to the styles and scripts array in under build target
NOTE: Before v6 the Angular CLI project configuration was stored in <PATH_TO_PROJECT>/.angular-cli.json. As of v6 the location of the file changed to angular.json. Since there is no longer a leading dot, the file is no longer hidden by default and is on the same level.
which also means that file paths in angular.json should not contain leading dots and slash

i.e you can provide an absolute path instead of a relative path

In .angular-cli.json file Path was "../node_modules/"
In angular.json it is "node_modules/"

 "build": {
          "builder": "@angular-devkit/build-angular:browser",
          "options": {
            "outputPath": "dist/ng6",
            "index": "src/index.html",
            "main": "src/main.ts",
            "polyfills": "src/polyfills.ts",
            "tsConfig": "src/tsconfig.app.json",
            "assets": [
              "src/favicon.ico",
              "src/assets"
            ],
            "styles": [
              "src/styles.css","node_modules/bootstrap/dist/css/bootstrap.min.css"
               
            ],
            "scripts": ["node_modules/jquery/dist/jquery.min.js",
                       "node_modules/bootstrap/dist/js/bootstrap.min.js"]
          },

OPTION 2
Add files from CDN (Content Delivery Network) to your project CDN LINK

Open file src/index.html and insert

the <link> element at the end of the head section to include the Bootstrap CSS file
a <script> element to include jQuery at the bottom of the body section
a <script> element to include Popper.js at the bottom of the body section
a <script> element to include the Bootstrap JavaScript file at the bottom of the body section

  <!doctype html>
    <html>
    <head>
      <meta charset="utf-8">
      <title>Angular</title>
      <base href="/">

    </body>
    </html>

OPTION 3
Execute npm install bootstrap
In src/styles.css add the following line:

@import "~bootstrap/dist/css/bootstrap.css";

OPTION-4
ng-bootstrap It contains a set of native Angular directives based on Bootstrap’s markup and CSS. As a result, it's not dependent on jQuery or Bootstrap’s JavaScript

npm install --save @ng-bootstrap/ng-bootstrap

After Installation import it in your root module and register it in @NgModule imports` array

import {NgbModule} from '@ng-bootstrap/ng-bootstrap';
@NgModule({
  declarations: [AppComponent, ...],
  imports: [NgbModule.forRoot(), ...],
  bootstrap: [AppComponent]
})

NOTE
ng-bootstrap requires Bootstrap's 4 css to be added in your project. you need to Install it explicitly via:
npm install bootstrap@4 --save In your angular.json add the file paths to the styles array in under build target

   "styles": [
      "src/styles.css",
      "node_modules/bootstrap/dist/css/bootstrap.min.css"
   ],

P.S Do Restart Your server

Also very late, but here is an answer from Karvy1 that worked well for me if you don't have pandas >=0.25 version: https://stackoverflow.com/a/52511166/10740287

For the example above you may write:

data = [(row.subject, row.trial_num, sample) for row in df.itertuples() for sample in row.samples]
data = pd.DataFrame(data, columns=['subject', 'trial_num', 'samples'])

Speed test:

%timeit data = pd.DataFrame([(row.subject, row.trial_num, sample) for row in df.itertuples() for sample in row.samples], columns=['subject', 'trial_num', 'samples'])

1.33 ms ± 74.8 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)

%timeit data = df.set_index(['subject', 'trial_num'])['samples'].apply(pd.Series).stack().reset_index()

4.9 ms ± 189 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

%timeit data = pd.DataFrame({col:np.repeat(df[col].values, df['samples'].str.len())for col in df.columns.drop('samples')}).assign(**{'samples':np.concatenate(df['samples'].values)})

1.38 ms ± 25 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)

Surprising that after such a long time there is still the best answer missing.

The downside of the other answers is using [0] to select the first character, but as noted, this breaks on the empty string.

Using the following circumvents this problem, and, in my opinion, gives the prettiest and most readable syntax of the options we have. It also does not import/bother with regex either):

>>> string = '1abc'
>>> string[:1].isdigit()
True

>>> string = ''
>>> string[:1].isdigit()
False

In Angular 5.12 and latest Angular CLI, do

ng generate service my-service -m app.module

Search for   or only nbsp - did you try this?

I had a similar issue. I've been bouncing between XCode 7 and 8 for a variety of reasons. Once you use 8 to build, you will need to use 8. I simply used Xcode 8 and applied some of the changes suggested above and it worked.

This query will use index if you have it for signup_date field

SELECT users.id, DATE_FORMAT(users.signup_date, '%Y-%m-%d') 
    FROM users 
    WHERE signup_date >= CURDATE() && signup_date < (CURDATE() + INTERVAL 1 DAY)

I stumbled across this for the same reason as anyone else. But the quoted scripts didn't quite work for me. I've made one that is more a hybrid of those I've seen and it now lives here - https://gitlab.com/inorton/git-size-calc

libcurl also provides CURLOPT_COOKIELIST which extracts all known cookies. All you need is to make sure the PHP/CURL binding can use it.

If you don't mind a bit more markup, this would work:

<div class="centered">
    <button class="btn btn-large btn-primary" type="button">Submit</button>
</div>

With the corresponding CSS rule:

.centered
{
    text-align:center;
}

I have to look at the CSS rules for the btn class, but I don't think it specifies a width, so auto left & right margins wouldn't work. If you added one of the span or input- rules to the button, auto margins would work, though.

Edit:

Confirmed my initial thought; the btn classes do not have a width defined, so you can't use auto side margins. Also, as @AndrewM notes, you could simply use the text-center class instead of creating a new ruleset.

$('body').toggleClass("className");

perfectly works

If you can use C libraries then one method would be to use sprintf, e.g.

#include <cstdio>

char s[32];

int len = sprintf(s, "%d", i);

The following sends standard output to the null device (bit bucket).

scriptname >/dev/null

And if you also want error messages to be sent there, use one of (the first may not work in all shells):

scriptname &>/dev/null
scriptname >/dev/null 2>&1
scriptname >/dev/null 2>/dev/null

And, if you want to record the messages, but not see them, replace /dev/null with an actual file, such as:

scriptname &>scriptname.out

For completeness, under Windows cmd.exe (where "nul" is the equivalent of "/dev/null"), it is:

scriptname >nul 2>nul

I'd recommend the DIY way which, combined with a good hashCode() and equals() method should be easy to proof in a unit test.

The reason the code isn't working is because lastrow is measured from whatever sheet is currently active, and "A:A500" (or other number) is not a valid range reference.

Private Sub CommandButton1_Click()
    Dim lastrow As Long

    lastrow = Sheets("Summary Info").Range("A65536").End(xlUp).Row    ' or + 1
    Range("A3:E3").Copy Destination:=Sheets("Summary Info").Range("A" & lastrow)
End Sub

You can achieve this with a few simple extension methods. The following Date extension method returns just the timezone component in ISO format, then you can define another for the date/time part and combine them for a complete date-time-offset string.

Date.prototype.getISOTimezoneOffset = function () {
    const offset = this.getTimezoneOffset();
    return (offset < 0 ? "+" : "-") + Math.floor(Math.abs(offset / 60)).leftPad(2) + ":" + (Math.abs(offset % 60)).leftPad(2);
}

Date.prototype.toISOLocaleString = function () {
    return this.getFullYear() + "-" + (this.getMonth() + 1).leftPad(2) + "-" +
        this.getDate().leftPad(2) + "T" + this.getHours().leftPad(2) + ":" +
        this.getMinutes().leftPad(2) + ":" + this.getSeconds().leftPad(2) + "." +
        this.getMilliseconds().leftPad(3);
}

Number.prototype.leftPad = function (size) {
    var s = String(this);
    while (s.length < (size || 2)) {
        s = "0" + s;
    }
    return s;
}

Example usage:

var date = new Date();
console.log(date.toISOLocaleString() + date.getISOTimezoneOffset());
// Prints "2020-08-05T16:15:46.525+10:00"

I know it's 2020 and most people are probably using Moment.js by now, but a simple copy & pastable solution is still sometimes handy to have.

(The reason I split the date/time and offset methods is because I'm using an old Datejs library which already provides a flexible toString method with custom format specifiers, but just doesn't include the timezone offset. Hence, I added toISOLocaleString for anyone without said library.)

Find the text nodes (nodeType==3) and replace the textContent:

$('#one').contents().filter(function() {
    return this.nodeType == 3
}).each(function(){
    this.textContent = this.textContent.replace('Hi I am text','Hi I am replace');
});

Note that as per the docs you can replace the hard-coded 3 in the above with Node.TEXT_NODE which is much clearer what you're doing.

$('#one').contents().filter(function() {
    return this.nodeType == Node.TEXT_NODE;
}).each(function(){
    this.textContent = this.textContent.replace('Hi I am text','Hi I am replace');
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="one">
       <div class="first"></div>
       "Hi I am text"
       <div class="second"></div>
       <div class="third"></div>
</div>

I know, all of the previous answers are insightful to your question. I had too like you this confusion just one minute before finding this SO thread. After reading some of the answers, here is what I get: A JSONObject is a JSON-like object that can be represented as an element in the array, the JSONArray. In other words, a JSONArray can contain a (or many) JSONObject.

The conflict message:

CONFLICT (delete/modify): res/layout/dialog_item.xml deleted in dialog and modified in HEAD

means that res/layout/dialog_item.xml was deleted in the 'dialog' branch you are merging, but was modified in HEAD (in the branch you are merging to).

So you have to decide whether

• remove file using "git rm res/layout/dialog_item.xml"

or

• accept version from HEAD (perhaps after editing it) with "git add res/layout/dialog_item.xml"

Then you finalize merge with "git commit".

Note that git will warn you that you are creating a merge commit, in the (rare) case where it is something you don't want. Probably remains from the days where said case was less rare.

The remote section also specifies fetch rules. You could add something like this into it to fetch all branches from the remote:

fetch = +refs/heads/*:refs/remotes/origin/*

(Or replace origin with bitbucket.)

Since Java SE 6, there's a builtin HTTP server in Sun Oracle JRE. The com.sun.net.httpserver package summary outlines the involved classes and contains examples.

Here's a kickoff example copypasted from their docs (to all people trying to edit it nonetheless, because it's an ugly piece of code, please don't, this is a copy paste, not mine, moreover you should never edit quotations unless they have changed in the original source). You can just copy'n'paste'n'run it on Java 6+.

package com.stackoverflow.q3732109;

import java.io.IOException;
import java.io.OutputStream;
import java.net.InetSocketAddress;

import com.sun.net.httpserver.HttpExchange;
import com.sun.net.httpserver.HttpHandler;
import com.sun.net.httpserver.HttpServer;

public class Test {

    public static void main(String[] args) throws Exception {
        HttpServer server = HttpServer.create(new InetSocketAddress(8000), 0);
        server.createContext("/test", new MyHandler());
        server.setExecutor(null); // creates a default executor
        server.start();
    }

    static class MyHandler implements HttpHandler {
        @Override
        public void handle(HttpExchange t) throws IOException {
            String response = "This is the response";
            t.sendResponseHeaders(200, response.length());
            OutputStream os = t.getResponseBody();
            os.write(response.getBytes());
            os.close();
        }
    }

}

Noted should be that the response.length() part in their example is bad, it should have been response.getBytes().length. Even then, the getBytes() method must explicitly specify the charset which you then specify in the response header. Alas, albeit misguiding to starters, it's after all just a basic kickoff example.

Execute it and go to http://localhost:8000/test and you'll see the following response:

This is the response

As to using com.sun.* classes, do note that this is, in contrary to what some developers think, absolutely not forbidden by the well known FAQ Why Developers Should Not Write Programs That Call 'sun' Packages. That FAQ concerns the sun.* package (such as sun.misc.BASE64Encoder) for internal usage by the Oracle JRE (which would thus kill your application when you run it on a different JRE), not the com.sun.* package. Sun/Oracle also just develop software on top of the Java SE API themselves like as every other company such as Apache and so on. Using com.sun.* classes is only discouraged (but not forbidden) when it concerns an implementation of a certain Java API, such as GlassFish (Java EE impl), Mojarra (JSF impl), Jersey (JAX-RS impl), etc.

This answer is for docker-compose version 2 and it also works on version 3

You can still access the data when you use depends_on.

If you look at docker docs Docker Compose and Django, you still can access the database like this:

version: '2'
services:
  db:
    image: postgres
  web:
    build: .
    command: python manage.py runserver 0.0.0.0:8000
    volumes:
      - .:/code
    ports:
      - "8000:8000"
    depends_on:
      - db

What is the difference between links and depends_on?

links:

When you create a container for a database, for example:

docker run -d --name=test-mysql --env="MYSQL_ROOT_PASSWORD=mypassword" -P mysql

docker inspect d54cf8a0fb98 |grep HostPort

And you may find

"HostPort": "32777"

This means you can connect the database from your localhost port 32777 (3306 in container) but this port will change every time you restart or remove the container. So you can use links to make sure you will always connect to the database and don't have to know which port it is.

web:
  links:
   - db

depends_on:

I found a nice blog from Giorgio Ferraris Docker-compose.yml: from V1 to V2

When docker-compose executes V2 files, it will automatically build a network between all of the containers defined in the file, and every container will be immediately able to refer to the others just using the names defined in the docker-compose.yml file.

And

So we don’t need links anymore; links were used to start a network communication between our db container and our web-server container, but this is already done by docker-compose

Update

depends_on

Express dependency between services, which has two effects:

• docker-compose up will start services in dependency order. In the following example, db and redis will be started before web.
• docker-compose up SERVICE will automatically include SERVICE’s dependencies. In the following example, docker-compose up web will also create and start db and redis.

Simple example:

version: '2'
services:
  web:
    build: .
    depends_on:
      - db
      - redis
  redis:
    image: redis
  db:
    image: postgres

Note: depends_on will not wait for db and redis to be “ready” before starting web - only until they have been started. If you need to wait for a service to be ready, see Controlling startup order for more on this problem and strategies for solving it.

I use these defines:

/** Use to init the clock */
#define TIMER_INIT \
    LARGE_INTEGER frequency; \
    LARGE_INTEGER t1,t2; \
    double elapsedTime; \
    QueryPerformanceFrequency(&frequency);


/** Use to start the performance timer */
#define TIMER_START QueryPerformanceCounter(&t1);

/** Use to stop the performance timer and output the result to the standard stream. Less verbose than \c TIMER_STOP_VERBOSE */
#define TIMER_STOP \
    QueryPerformanceCounter(&t2); \
    elapsedTime=(float)(t2.QuadPart-t1.QuadPart)/frequency.QuadPart; \
    std::wcout<<elapsedTime<<L" sec"<<endl;

Usage (brackets to prevent redefines):

TIMER_INIT

{
   TIMER_START
   Sleep(1000);
   TIMER_STOP
}

{
   TIMER_START
   Sleep(1234);
   TIMER_STOP
}

Output from usage example:

1.00003 sec
1.23407 sec

something like this:

List<string> test1 = new List<string> { "@bob.com", "@tom.com" };
List<string> test2 = new List<string> { "[email protected]", "[email protected]" };

var res = test2.Where(f => test1.Count(z => f.Contains(z)) == 0)

This looks OK for SQL Server 2008. For SS2005 & earlier, you need to repeat the VALUES statement.

INSERT INTO dbo.MyTable (ID, Name)  
VALUES (123, 'Timmy')  
VALUES (124, 'Jonny')   
VALUES (125, 'Sally')  

EDIT:: My bad. You have to repeat the 'INSERT INTO' for each row in SS2005.

INSERT INTO dbo.MyTable (ID, Name)  
VALUES (123, 'Timmy')  
INSERT INTO dbo.MyTable (ID, Name)  
VALUES (124, 'Jonny')   
INSERT INTO dbo.MyTable (ID, Name)  
VALUES (125, 'Sally')  

You should retrieve RecyclerView in a Fragment after inflating core View using that View. Perhaps it can't find your recycler because it's not part of Activity

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
    final View view = inflater.inflate(R.layout.fragment_artist_tracks, container, false);
    final FragmentActivity c = getActivity();
    final RecyclerView recyclerView = (RecyclerView) view.findViewById(R.id.recyclerView);
    LinearLayoutManager layoutManager = new LinearLayoutManager(c);
    recyclerView.setLayoutManager(layoutManager);

    new Thread(new Runnable() {
        @Override
        public void run() {
            final RecyclerAdapter adapter = new RecyclerAdapter(c);
            c.runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    recyclerView.setAdapter(adapter);
                }
            });
        }
    }).start();

    return view;
}

Try this. Your doing in wrong way.

You can have a datetime picker when using matInput with type datetime-local like so:

  <mat-form-field>
    <input matInput type="datetime-local" placeholder="start date">
  </mat-form-field>

You can click on each part of the placeholder to set the day, month, year, hours,minutes and whether its AM or PM.

I needed to extract text between tags and aggregate (by concat) the text including in innner tags.

/node() did the job, while /text() made half job

/text() only returned text not included in inner tags, because inner tags are not "text nodes". You may think, "just extract text included in the inner tags in an additional xpath", however, it becomes challenging to sort the text in this original order because you dont know where to place the aggregated text from the inner tags!because you dont know where to place the aggregated text from the inner nodes.

1. When U937 cells were infected with HIV-1,
2. no induction of NF-KB factor was detected

5. .

Finally, /node() did exactly what I wanted, because it gets the text from inner tags too.

But it uses mutt, not mail (or mailx).

Use timedelta to switch between timezones. All you need is the offset in hours between timezones. Don't have to fiddle with boundaries for all 6 elements of a datetime object. timedelta handles leap years, leap centuries, etc., too, with ease. You must first

from datetime import datetime, timedelta

Then if offset is the timezone delta in hours:

timeout = timein + timedelta(hours = offset)

where timein and timeout are datetime objects. e.g.

timein + timedelta(hours = -8)

converts from GMT to PST.

So, how to determine offset? Here is a simple function provided you only have a few possibilities for conversion without using datetime objects that are timezone "aware" which some other answers nicely do. A bit manual, but sometimes clarity is best.

def change_timezone(timein, timezone, timezone_out):
    '''
    changes timezone between predefined timezone offsets to GMT
    timein - datetime object
    timezone - 'PST', 'PDT', 'GMT' (can add more as needed)
    timezone_out - 'PST', 'PDT', 'GMT' (can add more as needed)
    ''' 
    # simple table lookup        
    tz_offset =  {'PST': {'GMT': 8, 'PDT': 1, 'PST': 0}, \
                  'GMT': {'PST': -8, 'PDT': -7, 'GMT': 0}, \
                  'PDT': {'GMT': 7, 'PST': -1, 'PDT': 0}}
    try:
        offset = tz_offset[timezone][timezone_out]
    except:
        msg = 'Input timezone=' + timezone + ' OR output time zone=' + \
            timezone_out + ' not recognized'
        raise DateTimeError(msg)

    return timein + timedelta(hours = offset)

After looking at the numerous answers and playing around with the tightest code I can think of (for now) it seems best that all applications, where time is important and mixed timezones must be accounted for, should make a real effort to make all datetime objects "aware". Then it would seem the simplest answer is:

timeout = timein.astimezone(pytz.timezone("GMT"))

to convert to GMT for example. Of course, to convert to/from any other timezone you wish, local or otherwise, just use the appropriate timezone string that pytz understands (from pytz.all_timezones). Daylight savings time is then also taken into account.

Adding some info to the previous answer from @linusg :

sklearn keeps a release history of all its changes. Think of checking it from time to time. Here is the link to the documentation.

As you can see in the documentation for the version 0.18, a new module was created called model_selection. Therefore it didn't exist in previous versions.

Update sklearn and it will work !

Try:

td, th {
  white-space: nowrap;
  overflow: hidden;
}

I was debugging a menu hover state with Chrome and did this to be able to see the hover state code:

In the Elements panel click over Toggle Element state button and select :hover.

In the Scripts panel go to Event Listeners Breakpoints in the right bottom section and select Mouse -> mouseup.

Now inspect the Menu and select the box you want. When you release the mouse button it should stop and show you the selected element hover state in the Elements panel (look at the Styles section).

I am assuming you want to pass the database name as a parameter and not just run:

SELECT  *
FROM    DBName.sys.tables
WHERE   Name LIKE '%XXX%'

If so, you could use dynamic SQL to add the dbname to the query:

DECLARE @DBName NVARCHAR(200) = 'YourDBName',
        @TableName NVARCHAR(200) = 'SomeString';

IF NOT EXISTS (SELECT 1 FROM master.sys.databases WHERE Name = @DBName)
    BEGIN
        PRINT 'DATABASE NOT FOUND';
        RETURN;
    END;

DECLARE @SQL NVARCHAR(MAX) = '  SELECT  Name
                                FROM    ' + QUOTENAME(@DBName) + '.sys.tables
                                WHERE   Name LIKE ''%'' + @Table + ''%''';

EXECUTE SP_EXECUTESQL @SQL, N'@Table NVARCHAR(200)', @TableName;

I'm surprised that nobody suggested guava solution yet:

com.google.common.collect.Iterables.get(collection, 0)
// or
com.google.common.collect.Iterables.get(collection, 0, defaultValue)
// or
com.google.common.collect.Iterables.getFirst(collection, defaultValue)

or if you expect single element:

com.google.common.collect.Iterables.getOnlyElement(collection, defaultValue)
// or
com.google.common.collect.Iterables.getOnlyElement(collection)

Since str_split() function is not multibyte safe, an easy solution to split UTF-8 encoded string is to use preg_split() with u (PCRE_UTF8) modifier.

preg_split( '//u', $str, null, PREG_SPLIT_NO_EMPTY )

I hope this will help to understand the relationship between .NET Standard API surface and other .NET platforms. Each interface represents a target framework and methods represents groups of APIs available on that target framework.

type log.txt

But that will give you the whole file. You could change it to:

echo %date%, %time% >> log.txt
echo %date%, %time% > log_last.txt
...
type log_last.txt

to get only the last one.

This is now possible in modern browsers using localeCompare. By passing the numeric: true option, it will smartly recognize numbers. You can do case-insensitive using sensitivity: 'base'. Tested in Chrome, Firefox, and IE11.

Here's an example. It returns 1, meaning 10 goes after 2:

'10'.localeCompare('2', undefined, {numeric: true, sensitivity: 'base'})

For performance when sorting large numbers of strings, the article says:

When comparing large numbers of strings, such as in sorting large arrays, it is better to create an Intl.Collator object and use the function provided by its compare property. Docs link

var collator = new Intl.Collator(undefined, {numeric: true, sensitivity: 'base'});_x000D_
var myArray = ['1_Document', '11_Document', '2_Document'];_x000D_
console.log(myArray.sort(collator.compare));

I tried the above solutions and I was still having difficulties. I had other files staged with two files that were deleted accidentally.

To undo the two deleted files I had to unstage all of the files:

git reset HEAD .

At that point I was able to do the checkout of the deleted items:

git checkout -- WorkingFolder/FileName.ext

Finally I was able to restage the rest of the files and continue with my commit.

For anyone looking for an Angular2 (2.4.8) solution, since this is a generically-popular question when searching:

<div *ngFor="let choice of choices">
  <input type="radio" [checked]="choice == defaultChoice">
</div>

This will add the checked attribute to the input given the condition, but will add nothing if the condition fails.

Do not do this:

[attr.checked]="choice == defaultChoice"

because this will add the attribute checked="false" to every other input element.

Since the browser only looks for the presence of the checked attribute (the key), ignoring its value, so the last input in the group will be checked.

Starting in iOS 6, you can use

-tableView:shouldHighlightRowAtIndexPath:

If you return NO, it disables both the selection highlighting and the storyboard triggered segues connected to that cell.

The method is called when a touch comes down on a row. Returning NO to that message halts the selection process and does not cause the currently selected row to lose its selected look while the touch is down.

UITableViewDelegate Protocol Reference

You can get info on the display from the DisplayMetrics struct:

DisplayMetrics metrics = getResources().getDisplayMetrics();

Though Android doesn't use a direct pixel mapping, it uses a handful of quantized Density Independent Pixel values then scales to the actual screen size. So the metrics.densityDpi property will be one of the DENSITY_xxx constants (120, 160, 213, 240, 320, 480 or 640 dpi).

If you need the actual lcd pixel density (perhaps for an OpenGL app) you can get it from the metrics.xdpi and metrics.ydpi properties for horizontal and vertical density respectively.

If you are targeting API Levels earlier than 4. The metrics.density property is a floating point scaling factor from the reference density (160dpi). The same value now provided by metrics.densityDpi can be calculated

int densityDpi = (int)(metrics.density * 160f);

If you "want to return a fixed value when the input parameter has a particular value", maybe you don't even need a mock and could use a dict along with its get method:

foo = {'input1': 'value1', 'input2': 'value2'}.get

foo('input1')  # value1
foo('input2')  # value2

This works well when your fake's output is a mapping of input. When it's a function of input I'd suggest using side_effect as per Amber's answer.

You can also use a combination of both if you want to preserve Mock's capabilities (assert_called_once, call_count etc):

self.mock.side_effect = {'input1': 'value1', 'input2': 'value2'}.get

This is what I did in my code, I have just tested and it worked fine, input type="date" does not support to set curdate automatically, so the way I used to overcome this limitation was using PHP code a simple code like this.

<html>
<head></head>
    <body>
        <form ...>
            <?php
                echo "<label for='submission_date'>Data de submissão</label>";
                echo "<input type='date' name='submission_date' min='2012-01-01' value='" . date('Y-m-d') . "' required/>";
            ?>
        </form>
    </body>
</html>

Hope it helps!

$resource("../rest/api"}).get();

returns an object.

$resource("../rest/api").query();

returns an array.

You must use :

return $resource('../rest/api.php?method=getTask&q=*').query();

    isset('user.permissions.saveProject', args);

    function isset(string, context) {
        try {
            var arr = string.split('.');
            var checkObj = context || window;

            for (var i in arr) {
                if (checkObj[arr[i]] === undefined) return false;
                checkObj = checkObj[arr[i]];
            }

            return true;
        } catch (e) {
            return false;
        }
    }

$query = "ALTER TABLE `" . $table_prefix . "posts_to_bookmark` 
          ADD COLUMN `ping_status` INT(1) NOT NULL 
          AFTER `<TABLE COLUMN BEFORE THIS COLUMN>`";

I believe you need to have ADD COLUMN and use AFTER, not BEFORE.

In case you want to place column at the beginning of a table, use the FIRST statement:

$query = "ALTER TABLE `" . $table_prefix . "posts_to_bookmark`
          ADD COLUMN `ping_status` INT(1) NOT NULL 
          FIRST";

http://dev.mysql.com/doc/refman/5.1/en/alter-table.html

You can do something like this:

var radios = document.getElementsByName('genderS');_x000D_
_x000D_
for (var i = 0, length = radios.length; i < length; i++) {_x000D_
  if (radios[i].checked) {_x000D_
    // do whatever you want with the checked radio_x000D_
    alert(radios[i].value);_x000D_
_x000D_
    // only one radio can be logically checked, don't check the rest_x000D_
    break;_x000D_
  }_x000D_
}

<label for="gender">Gender: </label>_x000D_
<input type="radio" name="genderS" value="1" checked="checked">Male</input>_x000D_
<input type="radio" name="genderS" value="0">Female</input>

Edit: Thanks HATCHA and jpsetung for your edit suggestions.

This was very simple now that I realize how to do it, thanks to all the answers for leading me to the solution. I had to abandon $.getScript() in order to specify the source of the script...sometimes doing things manually is best.

Solution

//great suggestion @Jasper
var len = $('script[src*="Javascript/MyScript.js"]').length; 

if (len === 0) {
        alert('script not loaded');

        loadScript('Javascript/MyScript.js');

        if ($('script[src*="Javascript/MyScript.js"]').length === 0) {
            alert('still not loaded');
        }
        else {
            alert('loaded now');
        }
    }
    else {
        alert('script loaded');
    }


function loadScript(scriptLocationAndName) {
    var head = document.getElementsByTagName('head')[0];
    var script = document.createElement('script');
    script.type = 'text/javascript';
    script.src = scriptLocationAndName;
    head.appendChild(script);
}

To extract joebloggs from this string in bash using parameter expansion without any extra processes...

MYVAR="/var/cpanel/users/joebloggs:DNS9=domain.com" 

NAME=${MYVAR%:*}  # retain the part before the colon
NAME=${NAME##*/}  # retain the part after the last slash
echo $NAME

Doesn't depend on joebloggs being at a particular depth in the path.

Summary

An overview of a few parameter expansion modes, for reference...

${MYVAR#pattern}     # delete shortest match of pattern from the beginning
${MYVAR##pattern}    # delete longest match of pattern from the beginning
${MYVAR%pattern}     # delete shortest match of pattern from the end
${MYVAR%%pattern}    # delete longest match of pattern from the end

So # means match from the beginning (think of a comment line) and % means from the end. One instance means shortest and two instances means longest.

You can get substrings based on position using numbers:

${MYVAR:3}   # Remove the first three chars (leaving 4..end)
${MYVAR::3}  # Return the first three characters
${MYVAR:3:5} # The next five characters after removing the first 3 (chars 4-9)

You can also replace particular strings or patterns using:

${MYVAR/search/replace}

The pattern is in the same format as file-name matching, so * (any characters) is common, often followed by a particular symbol like / or .

Examples:

Given a variable like

MYVAR="users/joebloggs/domain.com" 

Remove the path leaving file name (all characters up to a slash):

echo ${MYVAR##*/}
domain.com

Remove the file name, leaving the path (delete shortest match after last /):

echo ${MYVAR%/*}
users/joebloggs

Get just the file extension (remove all before last period):

echo ${MYVAR##*.}
com

NOTE: To do two operations, you can't combine them, but have to assign to an intermediate variable. So to get the file name without path or extension:

NAME=${MYVAR##*/}      # remove part before last slash
echo ${NAME%.*}        # from the new var remove the part after the last period
domain

The problem with merge sort is the merge, if you don't actually need to implement the merge, then it is pretty simple (for a vector of ints):

#include <algorithm>
#include <vector>
using namespace std;

typedef vector<int>::iterator iter;

void mergesort(iter b, iter e) {
    if (e -b > 1) {
        iter m = b + (e -b) / 2;
        mergesort(b, m);
        mergesort(m, e);
        inplace_merge(b, m, e);
    }
}

I always add a target="_blank" to the download link. This will open a new window, but as soon as the user clicks save, the new window is closed.

As a more general solution you might want to check out the Microsoft Power Toy for XP that adds the "Open Command Window Here" option when you right-click: http://www.microsoft.com/windowsxp/downloads/powertoys/xppowertoys.mspx

In Vista and Windows 7, you'll get that option if you hold down shift and right-click (this is built in).

Used below code to set driver type based on need of Headless / Head for both Firefox and chrome:

// Can pass browser type 

if brower.lower() == 'chrome':
    driver = webdriver.Chrome('..\drivers\chromedriver')
elif brower.lower() == 'headless chrome':
    ch_Options = Options()
    ch_Options.add_argument('--headless')
    ch_Options.add_argument("--disable-gpu")
    driver = webdriver.Chrome('..\drivers\chromedriver',options=ch_Options)
elif brower.lower() == 'firefox':
    driver = webdriver.Firefox(executable_path=r'..\drivers\geckodriver.exe')
elif brower.lower() == 'headless firefox':
    ff_option = FFOption()
    ff_option.add_argument('--headless')
    ff_option.add_argument("--disable-gpu")
    driver = webdriver.Firefox(executable_path=r'..\drivers\geckodriver.exe', options=ff_option)
elif brower.lower() == 'ie':
    driver = webdriver.Ie('..\drivers\IEDriverServer')
else:
    raise Exception('Invalid Browser Type')

What do you want to fade? The background or color attribute?

Currently you're changing the background color, but telling it to transition the color property. You can use all to transition all properties.

.clicker { 
    -moz-transition: all .2s ease-in;
    -o-transition: all .2s ease-in;
    -webkit-transition: all .2s ease-in;
    transition: all .2s ease-in;
    background: #f5f5f5; 
    padding: 20px;
}

.clicker:hover { 
    background: #eee;
}

Otherwise just use transition: background .2s ease-in.

String toUpperCaseFirstLetterOnly(String str) {
    String[] words = str.split(" ");
    StringBuilder ret = new StringBuilder();
    for(int i = 0; i < words.length; i++) {
        ret.append(Character.toUpperCase(words[i].charAt(0)));
        ret.append(words[i].substring(1));
        if(i < words.length - 1) {
            ret.append(' ');
        }
    }
    return ret.toString();
}

This issue often happens when we try to merge another branch changes from a wrong directory.

Ex:

Branch2\Branch1_SubDir$ svn merge -rStart:End Branch1
         ^^^^^^^^^^^^
   Merging at wrong location

A conflict that gets thrown on its execution is :

Tree conflict on 'Branch1_SubDir'
   > local missing or deleted or moved away, incoming dir edit upon merge

And when you select q to quit resolution, you get status as:

 M      .
!     C Branch1_SubDir
      >   local missing or deleted or moved away, incoming dir edit upon merge
!     C Branch1_AnotherSubDir
      >   local missing or deleted or moved away, incoming dir edit upon merge

which clearly means that the merge contains changes related to Branch1_SubDir and Branch1_AnotherSubDir, and these folders couldn't be found inside Branch1_SubDir(obviously a directory can't be inside itself).

How to avoid this issue at first place:

Branch2$ svn merge -rStart:End Branch1
 ^^^^
Merging at root location

The simplest fix for this issue that worked for me :

svn revert -R .

If you want to sort based on first column (which contains number value), then try this:

arr.sort(function(a,b){
  return a[0]-b[0]
})

If you want to sort based on second column (which contains string value), then try this:

arr.sort(function(a,b){
  return a[1].charCodeAt(0)-b[1].charCodeAt(0)
})

P.S. for the second case, you need to compare between their ASCII values.

Hope this helps.

Create a temp file first.

File tempFile = File.createTempFile(prefix, suffix);
tempFile.deleteOnExit();
FileOutputStream out = new FileOutputStream(tempFile);
IOUtils.copy(in, out);
return tempFile;

    var arr = ["20.0","40.1","80.2","400.3"],
    sum = 0;
$.each(arr,function(){sum+=parseFloat(this) || 0; });

Worked perfectly for what i needed. Thanks vol7ron

I had UnnecessaryStubbingException when I tried to use the when methods on a Spy object. Mockito.lenient() silenced the exception but the test results were not correct.

In case of Spy objects, one has to call the methods directly.

@ExtendWith(MockitoExtension.class)
@RunWith(JUnitPlatform.class)
class ArithmTest {

    @Spy
    private Arithm arithm;

    @Test
    void testAddition() {

        int res = arithm.add(2, 5);

        // doReturn(7).when(arithm).add(2, 5);
        assertEquals(res, 7);
    }
}

if you use ubuntu 16.04 (maybe and above) just do this

 sudo phpenmod mysqli
 sudo service php7.0-fpm restart

redirected uri is the location where the user will be redirected after successfully login to your app. for example to get access token for your app in facebook you need to subimt redirected uri which is nothing only the app Domain that your provide when you create your facebook app.

If you used the Visual Studio 2012 ASP.NET Web Forms Application template then you would have gotten that reference. I'm assuming it's the one you would get via Nuget instead of the framework System.Data.Entity reference.

private void Form1_Load(object sender, EventArgs e)
    {
        PictureBox pb = new PictureBox();
        pb.Location = new Point(0, 0);
        pb.Size = new Size(150, 150);
        pb.Image = Image.FromFile("E:\\Wallpaper (204).jpg");
        pb.Visible = true;
        this.Controls.Add(pb);
    }

My 2 cents addition to the answers here are:

1. With reference to Field or Property access (away from performance considerations) both are legitimately accessed by means of getters and setters, thus, my model logic can set/get them in the same manner. The difference comes to play when the persistence runtime provider (Hibernate, EclipseLink or else) needs to persist/set some record in Table A which has a foreign key referring to some column in Table B. In case of a Property access type, the persistence runtime system uses my coded setter method to assign the cell in Table B column a new value. In case of a Field access type, the persistence runtime system sets the cell in Table B column directly. This difference is not of importance in the context of a uni-directional relationship, yet it is a MUST to use my own coded setter method (Property access type) for a bi-directional relationship provided the setter method is well designed to account for consistency. Consistency is a critical issue for bi-directional relationships refer to this link for a simple example for a well-designed setter.

2. With reference to Equals/hashCode: It is impossible to use the Eclipse auto-generated Equals/hashCode methods for entities participating in a bi-directional relationship, otherwise they will have a circular reference resulting in a stackoverflow Exception. Once you try a bidirectional relationship (say OneToOne) and auto-generate Equals() or hashCode() or even toString() you will get caught in this stackoverflow exception.

1. The input tag doesn't have onsubmit handler. Instead, you should put your onsubmit handler on actual form tag, like this:
   
   <form name="loginform" onsubmit="validateForm()" method="post">
   
   Here are some useful links:

   • JavaScript Form Validation
   • Form onsubmit Event

2. For the form tag you can specify the request method, GET or POST. By default, the method is GET. One of the differences between them is that in case of GET method, the parameters are appended to the URL (just what you have shown), while in case of POST method there are not shown in URL.

   You can read more about the differences here.

UPDATE:

You should return the function call and also you can specify the URL in action attribute of form tag. So here is the updated code:

<form name="loginform" onSubmit="return validateForm();" action="main.html" method="post">
    <label>User name</label>
    <input type="text" name="usr" placeholder="username"> 
    <label>Password</label>
    <input type="password" name="pword" placeholder="password">
    <input type="submit" value="Login"/>
</form>

<script>
    function validateForm() {
        var un = document.loginform.usr.value;
        var pw = document.loginform.pword.value;
        var username = "username"; 
        var password = "password";
        if ((un == username) && (pw == password)) {
            return true;
        }
        else {
            alert ("Login was unsuccessful, please check your username and password");
            return false;
        }
  }
</script>

/ means the root of the current drive;

./ means the current directory;

../ means the parent of the current directory.

In HTML, elements containing nothing but normal whitespace characters are considered empty. A paragraph that contains just a normal space character will have zero height. A non-breaking space is a special kind of whitespace character that isn't considered to be insignificant, so it can be used as content for a non-empty paragraph.

Even if you consider CSS margins on paragraphs, since an "empty" paragraph has zero height, its vertical margins will collapse. This causes it to have no height and no margins, making it appear as if it were never there at all.

I've found that the best way to debug is to use the microsoft tool called DTCPing

1. Copy the file to both the server (DB) and the client (Application server/client pc)
   • Start it at the server and the client
   • At the server: fill in the client netbios computer name and try to setup a DTC connection
   • Restart both applications.
   • At the client: fill in the server netbios computer name and try to setup a DTC connection

I've had my fare deal of problems in our old company network, and I've got a few tips:

• if you get the error message "Gethostbyname failed" it means the computer can not find the other computer by its netbios name. The server could for instance resolve and ping the client, but that works on a DNS level. Not on a netbios lookup level. Using WINS servers or changing the LMHOST (dirty) will solve this problem.
• if you get an error "Acces Denied", the security settings don't match. You should compare the security tab for the msdtc and get the server and client to match. One other thing to look at is the RestrictRemoteClients value. Depending on your OS version and more importantly the Service Pack, this value can be different.
• Other connection problems:
  • The firewall between the server and the client must allow communication over port 135. And more importantly the connection can be initiated from both sites (I had a lot of problems with the firewall people in my company because they assumed only the server would open an connection on to that port)
  • The protocol returns a random port to connect to for the real transaction communication. Firewall people don't like that, they like to restrict the ports to a certain range. You can restrict the RPC dynamic port generation to a certain range using the keys as described in How to configure RPC dynamic port allocation to work with firewalls.

In my experience, if the DTCPing is able to setup a DTC connection initiated from the client and initiated from the server, your transactions are not the problem any more.

When it s annoying with warnings like: DevTools failed to load SourceMap: Could not load content for http://********/bootstrap/4.5.0/css/bootstrap.min.css.map: HTTP error: status code 404, net::ERR_HTTP_RESPONSE_CODE_FAILURE

if you want to check for the json empty case, we can directly use below code

String jsonString = {};
JSONObject jsonObject = new JSONObject(jsonString);
if(jsonObject.isEmpty()){
 System.out.println("json is empty");
} else{
 System.out.println("json is not empty");
}

this may help you.

If your platform matrix supports Java 7 then you can use like below

List<List<String>> myList = new ArrayList<>();

If you have numpy available:

>>> import numpy as np
>>> states = [False, False, False, False, True, True, False, True, False, False, False, False, False, False, False, False]
>>> np.where(states)[0]
array([4, 5, 7])

I'd suggest reading through the Firebase documentation. Specifically, see the Saving Data portion of the Firebase JavaScript Web Guide.

From the guide:

Getting the Unique ID Generated by push()

Calling push() will return a reference to the new data path, which you can use to get the value of its ID or set data to it. The following code will result in the same data as the above example, but now we'll have access to the unique push ID that was generated

// Generate a reference to a new location and add some data using push()
var newPostRef = postsRef.push({
 author: "gracehop",
 title: "Announcing COBOL, a New Programming Language"
});

// Get the unique ID generated by push() by accessing its key
var postID = newPostRef.key;

Source: https://firebase.google.com/docs/database/admin/save-data#section-ways-to-save

• A push generates a new data path, with a server timestamp as its key. These keys look like -JiGh_31GA20JabpZBfa, so not numeric.
• If you wanted to make a numeric only ID, you would make that a parameter of the object to avoid overwriting the generated key.
  • The keys (the paths of the new data) are guaranteed to be unique, so there's no point in overwriting them with a numeric key.
  • You can instead set the numeric ID as a child of the object.
  • You can then query objects by that ID child using Firebase Queries.

From the guide:

In JavaScript, the pattern of calling push() and then immediately calling set() is so common that we let you combine them by just passing the data to be set directly to push() as follows. Both of the following write operations will result in the same data being saved to Firebase:

// These two methods are equivalent:
postsRef.push().set({
  author: "gracehop",
  title: "Announcing COBOL, a New Programming Language"
});
postsRef.push({
  author: "gracehop",
  title: "Announcing COBOL, a New Programming Language"
});

Try

<td style="text-align:center;">
  <input type="checkbox" name="myTextEditBox" value="checked" />
</td>

Use this function:

def pretty_dict(d, n=1):
    for k in d:
        print(" "*n + k)
        try:
            pretty_dict(d[k], n=n+4)
        except TypeError:
            continue

Call it like this:

pretty_dict(mydict)

Try to update @angular/core using ng update @angular/cli @angular/core

This UnsupportedOperationException comes when you try to perform some operation on collection where its not allowed and in your case, When you call Arrays.asList it does not return a java.util.ArrayList. It returns a java.util.Arrays$ArrayList which is an immutable list. You cannot add to it and you cannot remove from it.

If you can stand to use sed (possibly execute from within your program, it'd be as simple as:

sed 's/(.*)//g'

If you're connecting to a named instance and UDP is not available when connecting to it, then you may need to specify the protocol as well.

Example: tcp:192.168.1.21\SQL2K5,1443

I know this question was old, but I wanted a solution that doesn't involve libraries outside those included JRE6 (i.e. Apache Commons is not acceptable), and I came up with a simple solution using the built-in java.io.StreamTokenizer:

import java.io.*;

// ...

String literal = "\"Has \\\"\\\\\\\t\\\" & isn\\\'t \\\r\\\n on 1 line.\"";
StreamTokenizer parser = new StreamTokenizer(new StringReader(literal));
String result;
try {
  parser.nextToken();
  if (parser.ttype == '"') {
    result = parser.sval;
  }
  else {
    result = "ERROR!";
  }
}
catch (IOException e) {
  result = e.toString();
}
System.out.println(result);

Output:

Has "\  " & isn't
 on 1 line.

BalusC's answer is right! but I have to mention according to the user instance variable such as:

rSet.last(); 
total = rSet.getRow();

and then which you are missing

rSet.beforeFirst();

the remaining code is same you will get your desire result.

You might want to combine it with a resize event:

 $(window).resize(function() {
  if ($(window).width() < 960) {
     alert('Less than 960');
  }
 else {
    alert('More than 960');
 }
});

For R.J.:

var eventFired = 0;

if ($(window).width() < 960) {
    alert('Less than 960');

}
else {
    alert('More than 960');
    eventFired = 1;
}

$(window).on('resize', function() {
    if (!eventFired) {
        if ($(window).width() < 960) {
            alert('Less than 960 resize');
        } else {
            alert('More than 960 resize');
        }
    }
});

I tried http://api.jquery.com/off/ with no success so I went with the eventFired flag.

Private Sub ListView1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles ListView1.Click
        Dim tt As String
        tt = ListView1.SelectedItems.Item(0).SubItems(1).Text
        TextBox1.Text = tt.ToString
End Sub

You can use EL if you want to work as IF:

<h:outputLabel value="#{row==10? '10' : '15'}"/>

Changing styles or classes:

style="#{test eq testMB.test? 'font-weight:bold' : 'font-weight:normal'}"

class="#{test eq testMB.test? 'divRred' : 'divGreen'}"

If you're looking to scatter by two variables and color by the third, Altair can be a great choice.

Creating the dataset

import matplotlib.pyplot as plt
import numpy as np
import pandas as pd

df = pd.DataFrame(40*np.random.randn(10, 3), columns=['A', 'B','C'])

Altair plot

from altair import *
Chart(df).mark_circle().encode(x='A',y='B', color='C').configure_cell(width=200, height=150)

The easiest way is probably to use two parameters: One for hosts (can be an array), and one for vlan.

param([String[]] $Hosts, [String] $VLAN)

Instead of

foreach ($i in $args)

you can use

foreach ($hostName in $Hosts)

If there is only one host, the foreach loop will iterate only once. To pass multiple hosts to the script, pass it as an array:

myScript.ps1 -Hosts host1,host2,host3 -VLAN 2

...or something similar.

This is an improved version of @schuttek's answer. It is improved because it correctly return false for primitives (e.g. isSubclassOf(int.class, Object.class) => false) and also correctly handles interfaces (e.g. isSubclassOf(HashMap.class, Map.class) => true).

static public boolean isSubclassOf(final Class<?> clazz, final Class<?> possibleSuperClass)
{
    if (clazz == null || possibleSuperClass == null)
    {
        return false;
    }
    else if (clazz.equals(possibleSuperClass))
    {
        return true;
    }
    else
    {
        final boolean isSubclass = isSubclassOf(clazz.getSuperclass(), possibleSuperClass);

        if (!isSubclass && clazz.getInterfaces() != null)
        {
            for (final Class<?> inter : clazz.getInterfaces())
            {
                if (isSubclassOf(inter, possibleSuperClass))
                {
                    return true;
                }
            }
        }

        return isSubclass;
    }
}

Although I've tried all the previous answers, only the following one worked out:

1 - Open Powershell (as Admin)

2 - Run:

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12

3 - Run:

For maven2 there isn't a way to do what you describe. For maven 3, there is. If you are using maven 3 please see another answer for this question

For maven 2 I'd recommend creating your own custom pom for the dependency that has your <exclusions>. For projects that need to use that dependency, set the dependency to your custom pom instead of the typical artifact. While that does not necessarily allow you exclude all transitive dependencies with a single <exclusion>, it does allow you only have to write your dependency once and all of your projects don't need to maintain unnecessary and long exclusion lists.

In case you have a spring project, you can also use the CollectionUtils.lastElement from Spring (javadoc) and you don't need to add an extra dependency like Google Guave if you didn't need to before.

It is null-safe so if you pass null, you will simply receive null in return. Be careful when handling the response though.

Here are somes unit test to demonstrate them:

@Test
void lastElementOfList() {
    var names = List.of("John", "Jane");

    var lastName = CollectionUtils.lastElement(names);

    then(lastName)
        .as("Expected Jane to be the last name in the list")
        .isEqualTo("Jane");
}

@Test
void lastElementOfSet() {
    var names = new TreeSet<>(Set.of("Jane", "John", "James"));

    var lastName = CollectionUtils.lastElement(names);

    then(lastName)
        .as("Expected John to be the last name in the list")
        .isEqualTo("John");
}

Note: org.assertj.core.api.BDDAssertions#then(java.lang.String) is used for assertions.

Maybe below sample project helps you;

https://github.com/reinaldoarrosi/MaskedEditText

That project contains a view class call MaskedEditText. As first, you should add it in your project.

Then you add below xml part in res/values/attrs.xml file of project;

<resources>
    <declare-styleable name="MaskedEditText">
        <attr name="mask" format="string" />
        <attr name="placeholder" format="string" />
    </declare-styleable>
</resources>

Then you will be ready to use MaskedEditText view.

As last, you should add MaskedEditText in your xml file what you want like below;

<packagename.currentfolder.MaskedEditText
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/maskedEditText"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:ems="10"
    android:text="5"
    app:mask="(999) 999-9999"
    app:placeholder="_" >

Of course that, you can use it programmatically.

After those steps, adding MaskedEditText will appear like below;

As programmatically, if you want to take it's text value as unmasked, you may use below row;

maskedEditText.getText(true);

To take masked value, you may send false value instead of true value in the getText method.

This is how to open any file:

from os import path

filepath = '...' # your path
file = open(filepath, 'r')

In my case eclipse is not showing parent class function on $this, so I perform below mention points and it starts works:-

I go to my /var/www/ folder and check for .metadata folder (Here check the .log file and it shows) Resource is out of sync with the file system: 1. Go to Eclipse --> Project --> Clean 2. Windows -- preferences --> General --> Workspace --> And set it to "Refresh Automatically"

After that boom - things gets start working :)

If you want to load variables from other files too then ado this :- Eclipse-->Windows-->Preferences-->Php-->Editor-->Content Assist --> and check "show variable from other files"

Then it will show element , variables and other functions also.

I resolved this problem writing function instead of procedure and using CROSS APPLY in SQL statement. This solution works on SQL 2005 and later versions.

u can use this:

protected void btnConfirm_Click(object sender, EventArgs e)
{
  Response.Redirect("Confirm.aspx");
}

#change-avatar-file is a file input #change-avatar-file is a img tag (the target of jcrop) The "key" is FR.onloadend Event https://developer.mozilla.org/en-US/docs/Web/API/FileReader

$('#change-avatar-file').change(function(){
        var currentImg;
        if ( this.files && this.files[0] ) {
            var FR= new FileReader();
            FR.onload = function(e) {
                $('#avatar-change-img').attr( "src", e.target.result );
                currentImg = e.target.result;
            };
            FR.readAsDataURL( this.files[0] );
            FR.onloadend = function(e){
                //console.log( $('#avatar-change-img').attr( "src"));
                var jcrop_api;

                $('#avatar-change-img').Jcrop({
                    bgFade:     true,
                    bgOpacity: .2,
                    setSelect: [ 60, 70, 540, 330 ]
                },function(){
                    jcrop_api = this;
                });
            }
        }
    });

Maybe placing the jquery.ui.widget.js as second after jquery.ui.core.js.

str2 is pointing to a statically allocated constant character array. You can't write to it/over it. You need to dynamically allocate space via the *alloc family of functions.

Nothing an author can do can choose to open in a new tab instead of a new window; it is a user preference. (Note that the default user preference in most browsers is for new tabs, so a trivial test on a browser where that preference hasn't been changed will not demonstrate this.)

CSS3 proposed target-new, but the specification was abandoned.

The reverse is not true; by specifying certain window features for the window in the third argument of window.open(), you can trigger a new window when the preference is for tabs.

You do not need to install or update any software for the JUnit. it is the part of Java Development tools and comes with almost most of the latest versions in Eclipse.

Go to your project. Right click onto that->Select buildpath->add library->select JUnit from the list ->select the version you want to work with-> done

build you project again to see the errors gone:)

I solved this issue by setting the Copy Local attribute of my project's references to true.

Googled "Permission denied (publickey). fatal: The remote end hung up unexpectedly", first result an exact SO dupe:

GitHub: Permission denied (publickey). fatal: The remote end hung up unexpectedly which links here in the accepted answer (from the original poster, no less): http://help.github.com/linux-set-up-git/

First of all, in your device go to Dev. Option -> ADB over Network after do it:

$ adb connect <your device adb network>
$ react-native run-android 

(or run-ios, by the way)

if this has successfully your device has installed app-debug.apk, open app-debug and go to Dev. Settings -> Debug server host & port for device, type in your machine's IP address (generally, System preference -> Network), as in the example below < your machine's IP address >:8081 (whihout inequality)

finally, execute the command below

$ react-native start --port=8081

try another ports, and verify that you machine and your device are same network.

Assuming you don't want to immediately decode it again like others are suggesting here, you can parse it to a string and then just strip the leading 'b and trailing '.

>>> x = "Hi there " 
>>> x = "Hi there ".encode("utf-8") 
>>> x
b"Hi there \xef\xbf\xbd"
>>> str(x)[2:-1]
"Hi there \\xef\\xbf\\xbd"   

You can also specify context location relatively to current classpath, which may be preferable

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath*:applicationContext*.xml</param-value>
</context-param>

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

Use calendar.isleap:

import calendar
print(calendar.isleap(1900))

You could perhaps use the if-let-where clause:

Swift 3:

if let string = string, !string.isEmpty {
    /* string is not blank */
}

Swift 2:

if let string = string where !string.isEmpty {
    /* string is not blank */
}

In SQL Server Management Studio, turn on SQLCMD mode from the Query menu. Then at the top of your script, type in the command below

:Connect server_name[\instance_name] [-l timeout] [-U user_name [-P password]

If you are connecting to multiple servers, be sure to insert GO between connections; otherwise your T-SQL won't execute on the server you're thinking it will.

EDIT: Official setuptools dox page:

If you have Python 2 >=2.7.9 or Python 3 >=3.4 installed from python.org, you will already have pip and setuptools, but will need to upgrade to the latest version:

On Linux or OS X:

pip install -U pip setuptools 

On Windows:

python -m pip install -U pip setuptools

Therefore the rest of this post is probably obsolete (e.g. some links don't work).

Distribute - is a setuptools fork which "offers Python 3 support". Installation instructions for distribute(setuptools) + pip:

curl -O http://python-distribute.org/distribute_setup.py
python distribute_setup.py
easy_install pip

Similar issue here.

UPDATE: Distribute seems to be obsolete, i.e. merged into Setuptools: Distribute is a deprecated fork of the Setuptools project. Since the Setuptools 0.7 release, Setuptools and Distribute have merged and Distribute is no longer being maintained. All ongoing effort should reference the Setuptools project and the Setuptools documentation.

You may try with instructions found on setuptools pypi page (I haven't tested this, sorry :( ):

wget https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py -O - | python
easy_install pip

You can use literal quoting:

stmt := q'[insert into MY_TBL (Col) values('ER0002')]';

Documentation for literals can be found here.

Alternatively, you can use two quotes to denote a single quote:

stmt := 'insert into MY_TBL (Col) values(''ER0002'')';

The literal quoting mechanism with the Q syntax is more flexible and readable, IMO.

First of all i say that you should google this as it is defined in detail in many places

Local
These variables only exist inside the specific function that creates them. They are unknown to other functions and to the main program. As such, they are normally implemented using a stack. Local variables cease to exist once the function that created them is completed. They are recreated each time a function is executed or called.

Global
These variables can be accessed (ie known) by any function comprising the program. They are implemented by associating memory locations with variable names. They do not get recreated if the function is recalled.

/* Demonstrating Global variables  */
    #include <stdio.h>
    int add_numbers( void );                /* ANSI function prototype */

    /* These are global variables and can be accessed by functions from this point on */
    int  value1, value2, value3;

    int add_numbers( void )
    {
        auto int result;
        result = value1 + value2 + value3;
        return result;
    }

    main()
    {
        auto int result;
        value1 = 10;
        value2 = 20;
        value3 = 30;        
        result = add_numbers();
        printf("The sum of %d + %d + %d is %d\n",
            value1, value2, value3, final_result);
    }


    Sample Program Output
    The sum of 10 + 20 + 30 is 60

The scope of global variables can be restricted by carefully placing the declaration. They are visible from the declaration until the end of the current source file.

#include <stdio.h>
void no_access( void ); /* ANSI function prototype */
void all_access( void );

static int n2;      /* n2 is known from this point onwards */

void no_access( void )
{
    n1 = 10;        /* illegal, n1 not yet known */
    n2 = 5;         /* valid */
}

static int n1;      /* n1 is known from this point onwards */

void all_access( void )
{
    n1 = 10;        /* valid */
    n2 = 3;         /* valid */
}

Static:
Static object is an object that persists from the time it's constructed until the end of the program. So, stack and heap objects are excluded. But global objects, objects at namespace scope, objects declared static inside classes/functions, and objects declared at file scope are included in static objects. Static objects are destroyed when the program stops running.
I suggest you to see this tutorial list

AUTO:
C, C++

(Called automatic variables.)

All variables declared within a block of code are automatic by default, but this can be made explicit with the auto keyword.[note 1] An uninitialized automatic variable has an undefined value until it is assigned a valid value of its type.[1]

Using the storage class register instead of auto is a hint to the compiler to cache the variable in a processor register. Other than not allowing the referencing operator (&) to be used on the variable or any of its subcomponents, the compiler is free to ignore the hint.

In C++, the constructor of automatic variables is called when the execution reaches the place of declaration. The destructor is called when it reaches the end of the given program block (program blocks are surrounded by curly brackets). This feature is often used to manage resource allocation and deallocation, like opening and then automatically closing files or freeing up memory.SEE WIKIPEDIA

A callable piece of code (routine) can be a Sub (called for a side effect/what it does) or a Function (called for its return value) or a mixture of both. As the docs for MsgBox

Displays a message in a dialog box, waits for the user to click a button, and returns a value indicating which button the user clicked.

MsgBox(prompt[, buttons][, title][, helpfile, context])

indicate, this routine is of the third kind.

The syntactical rules of VBScript are simple:

Use parameter list () when calling a (routine as a) Function

If you want to display a message to the user and need to know the user's reponse:

Dim MyVar
MyVar = MsgBox ("Hello World!", 65, "MsgBox Example")
   ' MyVar contains either 1 or 2, depending on which button is clicked.

Don't use parameter list () when calling a (routine as a) Sub

If you want to display a message to the user and are not interested in the response:

MsgBox "Hello World!", 65, "MsgBox Example"

This beautiful simplicity is messed up by:

The design flaw of using () for parameter lists and to force call-by-value semantics

>> Sub S(n) : n = n + 1 : End Sub
>> n = 1
>> S n
>> WScript.Echo n
>> S (n)
>> WScript.Echo n
>>
2
2

S (n) does not mean "call S with n", but "call S with a copy of n's value". Programmers seeing that

>> s = "value"
>> MsgBox(s)

'works' are in for a suprise when they try:

>> MsgBox(s, 65, "MsgBox Example")
>>
Error Number:       1044
Error Description:  Cannot use parentheses when calling a Sub

The compiler's leniency with regard to empty () in a Sub call. The 'pure' Sub Randomize (called for the side effect of setting the random seed) can be called by

Randomize()

although the () can neither mean "give me your return value) nor "pass something by value". A bit more strictness here would force prgrammers to be aware of the difference in

Randomize n

and

Randomize (n)

The Call statement that allows parameter list () in Sub calls:

s = "value" Call MsgBox(s, 65, "MsgBox Example")

which further encourage programmers to use () without thinking.

(Based on What do you mean "cannot use parentheses?")

this is pretty old, but if you are using Python 3.4 or above use PathLib.

# using OS
import os
path=os.path.dirname("C:/folder1/folder2/filename.xml")
print(path)
print(os.path.basename(path))

# using pathlib
import pathlib
path = pathlib.PurePath("C:/folder1/folder2/filename.xml")
print(path.parent)
print(path.parent.name)

This is impossible as you cannot return from an asynchronous call inside a synchronous method.

In this case you need to pass a callback to foo that will receive the return value

function foo(address, fn){
  geocoder.geocode( { 'address': address}, function(results, status) {
     fn(results[0].geometry.location); 
  });
}

foo("address", function(location){
  alert(location); // this is where you get the return value
});

The thing is, if an inner function call is asynchronous, then all the functions 'wrapping' this call must also be asynchronous in order to 'return' a response.

If you have a lot of callbacks you might consider taking the plunge and use a promise library like Q.

NB: this is LINQ to objects, I am not 100% sure if it work in LINQ to entities, and have no time to check it right now. In fact it isn't too difficult to translate it to x in [A, B, C] but you have to check for yourself.

So, instead of Contains as a replacement of the ???? in your code you can use Any which is more LINQ-uish:

// Filter the orders based on the order status
var filteredOrders = from order in orders.Order
                     where new[] { "A", "B", "C" }.Any(s => s == order.StatusCode)
                     select order;

It's the opposite to what you know from SQL this is why it is not so obvious.

Of course, if you prefer fluent syntax here it is:

var filteredOrders = orders.Order.Where(order => new[] {"A", "B", "C"}.Any(s => s == order.StatusCode));

Here we again see one of the LINQ surprises (like Joda-speech which puts select at the end). However it is quite logical in this sense that it checks if at least one of the items (that is any) in a list (set, collection) matches a single value.

You don't need to explicitly set GOROOT (Modern versions of Go can figure it out on their own based on the location of the go binary that you run).

Also, got the follow error when trying to work with vgo:

go: modules disabled inside GOPATH/src by GO111MODULE=auto; see 'go help modules'

Removing GOROOT, updating my GOPATH and export GO111MODULE="on" resolved the issue.

GOPATH see in here

GOPATH may be set to a colon-separated list of paths inside which Go code, package objects, and executables may be found.

Set a GOPATH to use goinstall to build and install your own code and external libraries outside of the Go tree (and to avoid writing Makefiles).

Because (a.y - b.y) is probably less then (a.x - b.x) and in your code the casting is done after the divide operation so the result is an integer so 0.

You should cast to float before the / operation
