Facebook's FQL documentation here tells you how to do it. Run the example SELECT name, fan_count FROM page WHERE page_id = 19292868552 and replace the page_id number with your page's id number and it will return the page name and the fan count.

See here if you want to grant a Facebook App permanent access to a page (even when you / the app owner are logged out):

http://developers.facebook.com/docs/opengraph/using-app-tokens/

"An App Access Token does not expire unless you refresh the application secret through your app settings."

If you are looking for a custom code instead of plugin, then this might help you. Facebook graph has under gone some changes since it has evolved. These steps are for the latest Graph API which I tried recently and worked well.

There are two main steps involved - 1. Getting Facebook Access Token, 2. Calling the Graph API passing the access token.

1. Getting the access token - Here is the step by step process to get the access token for your Facebook page. - Embed Facebook page feed on my website. As per this you need to create an app in Facebook developers page which would give you an App Id and an App Secret. Use these two and get the Access Token.

2. Calling the Graph API - This would be pretty simple once you get the access token. You just need to form a URL to Graph API with all the fields/properties you want to retrieve and make a GET request to this URL. Here is one example on how to do it in asp.net MVC. Embedding facebook feeds using asp.net mvc. This should be pretty similar in any other technology as it would be just a HTTP GET request.

Sample FQL Query: https://graph.facebook.com/FBPageName/posts?fields=full_picture,picture,link,message,created_time&limit=5&access_token=YOUR_ACCESS_TOKEN_HERE

You can install apps in simulator from Xcode 8.2

From Xcode 8.2,You can install an app (*.app) by dragging any previously built app bundle into the simulator window.

Note: You cannot install apps from the App Store in simulation environments.

The answers here are outdated. Now you can easily use a CSS3 transform without hardcoding a margin. This works on all elements, including elements with no width or dynamic width.

Horizontal center:

left: 50%;
transform: translateX(-50%);

Vertical center:

top: 50%;
transform: translateY(-50%);

Both horizontal and vertical:

left: 50%;
top: 50%;
transform: translate(-50%, -50%);

Compatibility is not an issue: http://caniuse.com/#feat=transforms2d

The SKU example used in the documentation was to provide the allowed characters in a new user-specified SKU.

I had the same problem as deke. I forgot to include the most important script: angular.js :)

<script type="text/javascript" src="bower_components/angular/angular.min.js"></script>

Use adb. With adb pull you can copy files from your device to your system, when the device is attached with USB.

Of course you also need the right permissions to access the directory your file is in. If not, you will need to root the device first.

If you find that many of the APKs are named "base.apk" you can also use this one line command to pull all the APKs off a phone you can access while renaming any "base.apk" names to the package name. This also fixes the directory not found issue for APK paths with seemingly random characters after the name:

for i in $(adb shell pm list packages | awk -F':' '{print $2}'); do adb pull "$(adb shell pm path $i | awk -F':' '{print $2}')"; mv base.apk $i.apk 2&> /dev/null ;done

If you get "adb: error: failed to stat remote object" that indicates you don't have the needed permissions. I ran this on a NON-rooted Moto Z2 and was able to download ALL the APKs I did not uninstall (see below) except youtube.

adb shell pm uninstall --user 0 com.android.cellbroadcastreceiver   <--- kills presidential alert app!

(to view users run adb shell pm list users) This is a way to remove/uninstall (not from the phone as it comes back with factory reset) almost ANY app WITHOUT root INCLUDING system apps (hint the annoying update app that updates your phone line it or not can be found by grepping for "ccc")

Here is the solution.

When you are receiving array from your database. and you are storing array data inside a variable but the variable defined as object. This time you will get the error.

I am receiving array from database and I'm stroing that array inside a variable 'bannersliders'. 'bannersliders' type is now 'any' but if you write 'bannersliders' is an object. Like bannersliders:any={}. So this time you are storing array data inside object type variable. So you find that error.

So you have to write variable like 'bannersliders:any;' or 'bannersliders:any=[]'.

Here I am giving an example.

<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.7.5/angular.min.js"></script>
bannersliders:any;
  getallbanner(){
    this.bannerService.getallbanner().subscribe(data=>{
      this.bannersliders =data;
   })
  }

Stream API

public void iterateStreamAPI(Map<String, Integer> map) {
    map.entrySet().stream().forEach(e -> System.out.println(e.getKey() + ":"e.getValue()));
}

More generic way in case qs has more than one dictionaries:

[int(v) for lst in qs for k, v in lst.items()]

--

>>> qs = [{u'a': 15L, u'b': 9L, u'a': 16L}, {u'a': 20, u'b': 35}]
>>> result_list = [int(v) for lst in qs for k, v in lst.items()]
>>> result_list
[16, 9, 20, 35]

List<Conversation> conversations = **jdbcTemplate**.**queryForList**(
            **SQL_QUERY**,
            new Object[] {userId, dateFrom, dateTo});  //placeholders values

Suppose the sql query is like

SQL_QUERY = "**select** info,count(*),IF(info is null , 'DATA' , 'NO DATA') **from** table where userId=? , dateFrom=? , dateTo=?";

**HERE userId=? , dateFrom=? , dateTo=?**

the question marks are place holders

**SQL_QUERY**,
            new Object[] {userId, dateFrom, dateTo});

It will go as an object array along with the sql query

In my case, the request was getting timed out. So all you need to do is to increase the time out while creating the HttpClient.

HttpClient client = new HttpClient();

client.Timeout = TimeSpan.FromMinutes(5);

As Frank suggested, this is best without regex. Here's (an ugly) one-liner:

match_string = orig_string[orig_string.index("("):len(orig_string)-orig_string[::-1].index(")")]

Matching the troll line est mentioned in his comment:

orig_string = "for (int i = 0; i < 10; doSomethingTo(\"(\"));"
match_string = orig_string[orig_string.index("("):len(orig_string)-orig_string[::-1].index(")")]

returns (int i = 0; i < 10; doSomethingTo("("))

This works by running through the string forward until it reaches the first open paren, and then backward until it reaches the first closing paren. It then uses these two indices to slice the string.

1. Under Window Administrative Tools, run ODBC Data Sources (32-bit).

2. Under the Drivers tab, check you have the Microsoft Excel Driver (*.xls, *.xlsx etc...) - the file name is ACEODBC.DLL

3. If this is missing, you will need to install the Microsoft Access Database Engine 2016 Redistributable.

You'll find the installer here https://www.microsoft.com/en-us/download/details.aspx?id=54920

4. Your connection should be:

Set objConn1 = Server.CreateObject("ADODB.Connection") 
objConn1.Provider = "Microsoft.ACE.OLEDB.12.0"   
objConn1.ConnectionString = "Data Source=" & pPath & ";Extended Properties=""Excel 12.0 Xml;HDR=YES;IMEX=1""" 

Here is some code from above added with actual action code (point 1 and 2);

func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
    let deleteAction = UIContextualAction(style: .destructive, title: "Delete") { _, _, completionHandler in

        // 1. remove object from your array
        scannedItems.remove(at: indexPath.row)
        // 2. reload the table, otherwise you get an index out of bounds crash
        self.tableView.reloadData()

        completionHandler(true)
    }
    deleteAction.backgroundColor = .systemOrange
    let configuration = UISwipeActionsConfiguration(actions: [deleteAction])
    configuration.performsFirstActionWithFullSwipe = true
    return configuration
}

in Python 3.x, the range() function got its own type. so in this case you must use iterator

list(range(1000))

I think this is a slightly neater solution:

df.insert(0, 'mean', df.pop("mean"))

This solution is somewhat similar to @JoeHeffer 's solution but this is one liner.

Here we remove the column "mean" from the dataframe and attach it to index 0 with the same column name.

Struggled with the same problem for some time. But after creating the directory structure src/main/java and putting the source(from the top of the package), it worked as expected.

The tutorial I tried with. After you execute gradle build, you will have to be able to find classes under build directory.

If the format of the id's in the two table varies then you want to join them, as such you can select to use an id from one-main table, say if you have table_customes and table_orders, and tha id for orders is like "101","102"..."110", just use one for customers

select customers.id, name, amount, date from customers.orders;

This worked for me:

window.location.replace(window.location.pathname)

I want to add that you can use the .WRITE clause for partial or full updates and high performance appends to varchar(max)/nvarchar(max) data types.

Here you can found full example of using .WRITE clause.

First post :)

For the OP, kristof's solution will work, unless there are issues with massive data and transaction log balloon issues on big deletes. Also, even with tlog storage to spare, since deletes write to the tlog, the operation can take a VERY long time for tables with hundreds of millions of rows.

I use a series of cursors to truncate and reload large copies of one of our huge production databases frequently. The solution engineered accounts for multiple schemas, multiple foreign key columns, and best of all can be sproc'd out for use in SSIS.

It involves creation of three staging tables (real tables) to house the DROP, CREATE, and CHECK FK scripts, creation and insertion of those scripts into the tables, and then looping over the tables and executing them. The attached script is four parts: 1.) creation and storage of the scripts in the three staging (real) tables, 2.) execution of the drop FK scripts via a cursor one by one, 3.) Using sp_MSforeachtable to truncate all the tables in the database other than our three staging tables and 4.) execution of the create FK and check FK scripts at the end of your ETL SSIS package.

Run the script creation portion in an Execute SQL task in SSIS. Run the "execute Drop FK Scripts" portion in a second Execute SQL task. Put the truncation script in a third Execute SQL task, then perform whatever other ETL processes you need to do prior to attaching the CREATE and CHECK scripts in a final Execute SQL task (or two if desired) at the end of your control flow.

Storage of the scripts in real tables has proven invaluable when the re-application of the foreign keys fails as you can select * from sync_CreateFK, copy/paste into your query window, run them one at a time, and fix the data issues once you find ones that failed/are still failing to re-apply.

Do not re-run the script again if it fails without making sure that you re-apply all of the foreign keys/checks prior to doing so, or you will most likely lose some creation and check fk scripting as our staging tables are dropped and recreated prior to the creation of the scripts to execute.

ROUND ( 123.456 , 2 , 1 )

When the third parameter != 0 it truncates rather than rounds

http://msdn.microsoft.com/en-us/library/ms175003(SQL.90).aspx

Syntax

ROUND ( numeric_expression , length [ ,function ] )

Arguments

• numeric_expression Is an expression of the exact numeric or approximate numeric data type category, except for the bit data type.

• length Is the precision to which numeric_expression is to be rounded. length must be an expression of type tinyint, smallint, or int. When length is a positive number, numeric_expression is rounded to the number of decimal positions specified by length. When length is a negative number, numeric_expression is rounded on the left side of the decimal point, as specified by length.

• function Is the type of operation to perform. function must be tinyint, smallint, or int. When function is omitted or has a value of 0 (default), numeric_expression is rounded. When a value other than 0 is specified, numeric_expression is truncated.

OK, here is how I did it in Notepad++:

• Plugins
• Plugin manager
• Show plugin manager
• Check XML tools
• Install
• Restart Notepad++
• Open XML file
• Plugins
• XML tools
• Pretty print (XML only -- with line breaks)

I am also using this approach for csv files (Python 3.6.9):

import csv
import io
import requests

r = requests.get(url)
buff = io.StringIO(r.text)
dr = csv.DictReader(buff)
for row in dr:
    print(row)

Update to the latest conda and latest navigator will resolve this issue.

Open the Anaconda Prompt and type

• conda update conda

and

• conda update anaconda-navigator

To solve the issue of customisation and appearance of the ticks, see the Tick Locators guide on the matplotlib website

ax.xaxis.set_major_locator(plt.MaxNLocator(3))

Would set the total number of ticks in the x-axis to 3, and evenly distribute it across the axis.

There is also a nice tutorial about this

Here is a one liner. A little improvised answer using format with print() to iterate a list.

How about this (python 3.x):

sample_list = ['cat', 'dog', 'bunny', 'pig']
print("Your list of animals are: {}, {}, {} and {}".format(*sample_list))

Read the docs here on using format().

This is what I did:

$ wget http://sourceforge.net/projects/mcrypt/files/Libmcrypt/2.5.8/libmcrypt-2.5.8.tar.gz/download
$ tar xzvf libmcrypt-2.5.8.tar.gz
$ ./configure
$ make
$ sudo make install

$ brew install autoconf

$ wget file:///Users/rmatikolai/Downloads/php-5.4.24.tar.bz2
$ tar xjvf php-5.4.24.tar.bz2
$ cd php-5.4.24/ext/mcrypt
$ phpize
$ ./configure # this is the step which fails without the above dependencies
$ make
$ make test
$ sudo make install


$ sudo cp /private/etc/php.ini.default /private/etc/php.ini
$ sudo vi /private/etc/php.ini

Next, you need to add the line:

extension=mcrypt.so

$ sudo apachectl restart

You don't say what module you want to install - hence npm looks for a file package.json which describes your dependencies, and obviously this file is missing.

So either you have to explicitly tell npm which module to install, e.g.

npm install express

or

npm install -g express-generator

or you have to add a package.json file and register your modules here. The easiest way to get such a file is to let npm create one by running

npm init

and then add what you need. Please note that this does only work for locally installed modules, not for global ones.

A simple example might look like this:

{
  "name": "myapp",
  "version": "0.0.1",
  "dependencies": {
    "express": "4.0.0"
  }
}

or something like that. For more info on the package.json file see its official documentation and this interactive guide.

If it's a table-value function (returns a table set) you simply join it as a Table

this function generates one column table with all the values from passed comma-separated list

SELECT * FROM dbo.udf_generate_inlist_to_table('1,2,3,4')

Here is another nice solution for the Max functionality using T-SQL and SQL Server

SELECT [Other Fields],
  (SELECT Max(v) 
   FROM (VALUES (date1), (date2), (date3),...) AS value(v)) as [MaxDate]
FROM [YourTableName]

This can happen on Windows after a java update where the old version of the java SDK is missing and a new one is present. I would check if your IDE is using the installed java SDK version (IntelliJ: CTRL + SHIFT + ALT + S)

using json.loads will turn your data into a python dictionary.

Dictionaries values are accessed using ['key']

resp_str = {
  "name" : "ns1:timeSeriesResponseType",
  "declaredType" : "org.cuahsi.waterml.TimeSeriesResponseType",
  "scope" : "javax.xml.bind.JAXBElement$GlobalScope",
  "value" : {
    "queryInfo" : {
      "creationTime" : 1349724919000,
      "queryURL" : "http://waterservices.usgs.gov/nwis/iv/",
      "criteria" : {
        "locationParam" : "[ALL:103232434]",
        "variableParam" : "[00060, 00065]"
      },
      "note" : [ {
        "value" : "[ALL:103232434]",
        "title" : "filter:sites"
      }, {
        "value" : "[mode=LATEST, modifiedSince=null]",
        "title" : "filter:timeRange"
      }, {
        "value" : "sdas01",
        "title" : "server"
      } ]
    }
  },
  "nil" : false,
  "globalScope" : true,
  "typeSubstituted" : false
}

would translate into a python diction

resp_dict = json.loads(resp_str)

resp_dict['name'] # "ns1:timeSeriesResponseType"

resp_dict['value']['queryInfo']['creationTime'] # 1349724919000

First you are linking the file that is here:

<script src="../Script/login.js"> 

Which would lead the website to a file in the Folder Script, but then in the second paragraph you are saying that the folder name is

and also i have onother folder named scripts that contains the the following login.js file

So, this won't work! Because you are not accessing the correct file. To do that please write the code as

<script src="/script/login.js"></script>

Try removing the .. from the beginning of the code too.

This way, you'll reach the js file where the function would run!

Just to make sure:

Just to make sure that the files are attached the HTML DOM, then please open Developer Tools (F12) and in the network workspace note each request that the browser makes to the server. This way you will learn which files were loaded and which weren't, and also why they were not!

Good luck.

Since the original question was about the SerializableAttribute, it should be noted that this attribute only applies when using the BinaryFormatter or SoapFormatter.

It is a bit confusing, unless you really pay attention to the details, as to when to use it and what its actual purpose is.

It has NOTHING to do with XML or JSON serialization.

Used with the SerializableAttribute are the ISerializable Interface and SerializationInfo Class. These are also only used with the BinaryFormatter or SoapFormatter.

Unless you intend to serialize your class using Binary or Soap, do not bother marking your class as [Serializable]. XML and JSON serializers are not even aware of its existence.

net use \\<host> /delete should work, but many times it does not.

net stop workstation as @DaveInCaz offered works in such cases.

I have some why and hows I couldn't fit into a comment.

• It's not enough to restart the Workstation service (e.g. from services.msc console)
  The service probably needs to be disabled for some short period of time. If you do this restart from a script, might be better to add a 1 second delay.

• In cases when net use \\<host> /delete does not work because another program is still using that share, you can identify such program and remove the blocking handle without closing it. Use Sysinternals Process Explorer, press Ctrl+F for search and enter the name of host machine owning such share. Click on each result, program window behind search dialog jumps to found program's handle. Right click that handle and select Close Handle. (or just close such program if you can) This works only in regular cases where there really is a program blocking the share disconnect. Not in those weird cases when it's blocked for no reason.

• elevated account has it's own environment. This brings some unexpected behavior.
  If you do net use command in an elevated cmd/PS console, it will not affect which user will Windows Explorer use to access the share.
  And also other way around, if you run a program from the share and the program will ask and get elevated access, that program will loose connection to that share and any files it might need to run. You need to run net use from elevated cmd/PS to create an elevated share connection to that share.

• Removing Recent folders from Quick Access in Windows Explorer (top of left panel) might help in certain cases.
  If the Host you are connecting to offers different access levels based on user, and/or has a Guest user (anonymous) share access, this is a situation you might often run into.
  When you access a share using your username, folder inside such share might get assigned to Quick Access panel as a Recent item. When you open Windows Explorer after restart, Recent items inside Quick Access will be checked and a connection will be made to the Host machine and will stay open in form of a MUP. If your share accepts both authorized and anonymous connections, just opening Windows Explorer will create anonymous connection and when you click on a share which needs authorization, you will not get credential dialog but an error.

When use CMS GC in jdk1.8 will appeare this error, i change the G1 Gc solve this problem.

You could do:

$posted = preg_replace('/ By.*/', '', $posted);
echo $posted;

You simply use the apply() function:

R> M <- matrix(1:6, nrow=3, byrow=TRUE)
R> M
     [,1] [,2]
[1,]    1    2
[2,]    3    4
[3,]    5    6
R> apply(M, 1, function(x) 2*x[1]+x[2])
[1]  4 10 16
R> 

This takes a matrix and applies a (silly) function to each row. You pass extra arguments to the function as fourth, fifth, ... arguments to apply().

Use Guava's BigIntegerMath as follows:

BigInteger factorial = BigIntegerMath.factorial(n);

(Similar functionality for int and long is available in IntMath and LongMath respectively.)

You have a orWhereIn function in Laravel. It takes the same parameters as the whereIn function.

It's not in the documentation but you can find it in the laravel API. http://laravel.com/api/4.1/

That should give you this:

$query-> orWhereIn('products.value', $f);

You need to do encode on tmp[0], not on tmp.

tmp is not a string. It contains a (Unicode) string.

Try running type(tmp) and print dir(tmp) to see it for yourself.

You create the relationships the other way around; add foreign keys to the Person type to create a Many-to-One relationship:

class Person(models.Model):
    name = models.CharField(max_length=50)
    birthday = models.DateField()
    anniversary = models.ForeignKey(
        Anniversary, on_delete=models.CASCADE)
    address = models.ForeignKey(
        Address, on_delete=models.CASCADE)

class Address(models.Model):
    line1 = models.CharField(max_length=150)
    line2 = models.CharField(max_length=150)
    postalcode = models.CharField(max_length=10)
    city = models.CharField(max_length=150)
    country = models.CharField(max_length=150)

class Anniversary(models.Model):
    date = models.DateField()

Any one person can only be connected to one address and one anniversary, but addresses and anniversaries can be referenced from multiple Person entries.

Anniversary and Address objects will be given a reverse, backwards relationship too; by default it'll be called person_set but you can configure a different name if you need to. See Following relationships "backward" in the queries documentation.

In the real world, an application will almost always have java bean or domain that is to be serialized/de-serialized to/from JSON. Its already mentioned that JSON Object specification does not guarantee order and any manipulation to that behavior does not justify the requirement. I had the same scenario in my application where I needed to preserve order just for the sack of readability purpose. I used standard jackson way to serialize my java bean to JSON:

Object object = getObject();  //the source java bean that needs conversion
String jsonString = new com.fasterxml.jackson.databind.ObjectMapper().writeValueAsString(object);

In order to make the json with an ordered set of elements I just use JSON property annotation in the the Java bean I used for conversion. An example below:

@JsonInclude(JsonInclude.Include.NON_NULL)
@JsonPropertyOrder({"name","phone","city","id"})
public class SampleBean implements Serializable {
    private int id;
    private String name:
    private String city;
    private String phone;

    //...standard getters and setters
}

the getObject() used above:

public SampleBean getObject(){
    SampleBean bean  = new SampleBean();
    bean.setId("100");
    bean.setName("SomeName");
    bean.setCity("SomeCity");
    bean.setPhone("1234567890");
    return bean;
}

The output shows as per Json property order annotation:

{
    name: "SomeName",
    phone: "1234567890",
    city: "SomeCity",
    id: 100
}

If you are using jQuery UI you have translations for common key codes. In ui/ui/ui.core.js:

$.ui.keyCode = { 
    ...
    ENTER: 13, 
    ...
};

There's also some translations in tests/simulate/jquery.simulate.js but I could not find any in the core JS library. Mind you, I merely grep'ed the sources. Maybe there is some other way to get rid of these magic numbers.

You can also make use of String.charCodeAt and .fromCharCode:

>>> String.charCodeAt('\r') == 13
true
>>> String.fromCharCode(13) == '\r'
true

There are couple of little visual studio extensions for this purpose:

1. For VS2010 & TFS 2010, try this
2. For VS2012 & TFS 2010, use this

In case of TFS 2012, looks like there is no need for 'Go offline' extensions. I read something about a new feature called local workspace for the similar purpose.

Alternatively I had good success with Git-TF. All the goodness of git and when you are ready, you can push it to TFS.

  a === "a" ? do something

From inside the Service class:

Intent dialogIntent = new Intent(this, MyActivity.class);
dialogIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(dialogIntent);

In PostGIS, for points with latitude and longitude there is geography datatype.

To add a column:

alter table your_table add column geog geography;

To insert data:

insert into your_table (geog) values ('SRID=4326;POINT(longitude latitude)');

4326 is Spatial Reference ID that says it's data in degrees longitude and latitude, same as in GPS. More about it: http://epsg.io/4326

Order is Longitude, Latitude - so if you plot it as the map, it is (x, y).

To find closest point you need first to create spatial index:

create index on your_table using gist (geog);

and then request, say, 5 closest to a given point:

select * 
from your_table 
order by geog <-> 'SRID=4326;POINT(lon lat)' 
limit 5;

I needed the same and this solution worked the most simple and straightforward way:

http://www.farinspace.com/jquery-scrollable-table-plugin/

I just give an id to the table I want to scroll and put one line in Javascript. That's it!

By the way, first I also thought I want to use a scrollable div, but it is not necessary at all. You can use a div and put it into it, but this solution does just what we need: scrolls the table.

Here too I can reproduce this problem with scrapy and psycopg2 (both require C++ compiling), even though I have Microsoft Visual C++ Compiler for Python 2.7 installed.

It has to be noted that I use virtualenv. From your post I'm not sure whether you do the same.

Anyway I tried to skip the activation of the virtual environment. Then both scrapy and psycopg2 installed fine.

My hypothesis: there is a conflict between this 2014 C++ compiler for Python and virtualenv. I do not know why nor how to solve it (and I'd be glad if someone can suggest a workaround).

Because ( is special in regex, you should escape it \( when matching. However, depending on what language you are using, you can easily match ( with string methods like index() or other methods that enable you to find at what position the ( is in. Sometimes, there's no need to use regex.

Have a look at the shutil package, especially rmtree and copytree. You can check if a file / path exists with os.paths.exists(<path>).

import shutil
import os

def copy_and_overwrite(from_path, to_path):
    if os.path.exists(to_path):
        shutil.rmtree(to_path)
    shutil.copytree(from_path, to_path)

Vincent was right about copytree not working, if dirs already exist. So distutils is the nicer version. Below is a fixed version of shutil.copytree. It's basically copied 1-1, except the first os.makedirs() put behind an if-else-construct:

import os
from shutil import *
def copytree(src, dst, symlinks=False, ignore=None):
    names = os.listdir(src)
    if ignore is not None:
        ignored_names = ignore(src, names)
    else:
        ignored_names = set()

    if not os.path.isdir(dst): # This one line does the trick
        os.makedirs(dst)
    errors = []
    for name in names:
        if name in ignored_names:
            continue
        srcname = os.path.join(src, name)
        dstname = os.path.join(dst, name)
        try:
            if symlinks and os.path.islink(srcname):
                linkto = os.readlink(srcname)
                os.symlink(linkto, dstname)
            elif os.path.isdir(srcname):
                copytree(srcname, dstname, symlinks, ignore)
            else:
                # Will raise a SpecialFileError for unsupported file types
                copy2(srcname, dstname)
        # catch the Error from the recursive copytree so that we can
        # continue with other files
        except Error, err:
            errors.extend(err.args[0])
        except EnvironmentError, why:
            errors.append((srcname, dstname, str(why)))
    try:
        copystat(src, dst)
    except OSError, why:
        if WindowsError is not None and isinstance(why, WindowsError):
            # Copying file access times may fail on Windows
            pass
        else:
            errors.extend((src, dst, str(why)))
    if errors:
        raise Error, errors

Please note that if you have multiple application.properties files throughout your codebase, then try adding your value to the parent project's property file.

You can check your project's pom.xml file to identify what the parent project of your current project is.

Alternatively, try using environment.getProperty() instead of @Value.

Why not just run this: No need for special permissions

SELECT
    name, 
    object_id, 
    create_date, 
    modify_date
FROM
    sys.tables 
WHERE 
    name like '%yourTablePattern%'
ORDER BY
    modify_date

This is similar to Kannan's answer. However, this fixes an issue where the token should not be sent to cross-domain sites. This will only set the header if it is a local request.

HTML:

<meta name="csrf-token" content="{{ csrf_token() }}">

JS:

$.ajaxSetup({
    beforeSend: function(xhr, type) {
        if (!type.crossDomain) {
            xhr.setRequestHeader('X-CSRF-Token', $('meta[name="csrf-token"]').attr('content'));
        }
    },
});

You need to call the AddAddress method once for every recipient. Like so:

$mail->AddAddress('[email protected]', 'Person One');
$mail->AddAddress('[email protected]', 'Person Two');
// ..

Better yet, add them as Carbon Copy recipients.

$mail->AddCC('[email protected]', 'Person One');
$mail->AddCC('[email protected]', 'Person Two');
// ..

To make things easy, you should loop through an array to do this.

$recipients = array(
   '[email protected]' => 'Person One',
   '[email protected]' => 'Person Two',
   // ..
);
foreach($recipients as $email => $name)
{
   $mail->AddCC($email, $name);
}

There are a few different limits that might come in to play in determining the number of connections an Oracle database supports. The simplest approach would be to use the SESSIONS parameter and V$SESSION, i.e.

The number of sessions the database was configured to allow

SELECT name, value 
  FROM v$parameter
 WHERE name = 'sessions'

The number of sessions currently active

SELECT COUNT(*)
  FROM v$session

As I said, though, there are other potential limits both at the database level and at the operating system level and depending on whether shared server has been configured. If shared server is ignored, you may well hit the limit of the PROCESSES parameter before you hit the limit of the SESSIONS parameter. And you may hit operating system limits because each session requires a certain amount of RAM.

Got the solution and it's working fine. Set the environment variables as:

• CATALINA_HOME=C:\Program Files\Java\apache-tomcat-7.0.59\apache-tomcat-7.0.59 (path where your Apache Tomcat is)
• JAVA_HOME=C:\Program Files\Java\jdk1.8.0_25; (path where your JDK is)
• JRE_Home=C:\Program Files\Java\jre1.8.0_25; (path where your JRE is)
• CLASSPATH=%JAVA_HOME%\bin;%JRE_HOME%\bin;%CATALINA_HOME%\lib

Try this:

body
{
    font-family:your font;
    font-size:your value;
    font-weight:your value;
}

I'm not entirely sure but I think you are probably surprised at how arrays are serialized in JSON. Let's isolate the problem. Consider following code:

var display = Array();
display[0] = "none";
display[1] = "block";
display[2] = "none";

console.log( JSON.stringify(display) );

This will print:

["none","block","none"]

This is how JSON actually serializes array. However what you want to see is something like:

{"0":"none","1":"block","2":"none"}

To get this format you want to serialize object, not array. So let's rewrite above code like this:

var display2 = {};
display2["0"] = "none";
display2["1"] = "block";
display2["2"] = "none";

console.log( JSON.stringify(display2) );

This will print in the format you want.

You can play around with this here: http://jsbin.com/oDuhINAG/1/edit?js,console

The return statement you have is stuck in the inner function, so it won't return from the outer function. You just need a little more code:

function getMachine(color, qty) {
    var returnValue = null;
    $("#getMachine li").each(function() {
        var thisArray = $(this).text().split("~");
        if(thisArray[0] == color&& qty>= parseInt(thisArray[1]) && qty<= parseInt(thisArray[2])) {
            returnValue = thisArray[3];
            return false; // this breaks out of the each
        }
    });
    return returnValue;
}

var retval = getMachine(color, qty);

With Git 2.3.2+ (Q1 2015), there is one other case where Git will not follow symlink anymore: see commit e0d201b by Junio C Hamano (gitster) (main Git maintainer)

apply: do not touch a file beyond a symbolic link

Because Git tracks symbolic links as symbolic links, a path that has a symbolic link in its leading part (e.g. path/to/dir/file, where path/to/dir is a symbolic link to somewhere else, be it inside or outside the working tree) can never appear in a patch that validly applies, unless the same patch first removes the symbolic link to allow a directory to be created there.

Detect and reject such a patch.

Similarly, when an input creates a symbolic link path/to/dir and then creates a file path/to/dir/file, we need to flag it as an error without actually creating path/to/dir symbolic link in the filesystem.

Instead, for any patch in the input that leaves a path (i.e. a non deletion) in the result, we check all leading paths against the resulting tree that the patch would create by inspecting all the patches in the input and then the target of patch application (either the index or the working tree).

This way, we:

• catch a mischief or a mistake to add a symbolic link path/to/dir and a file path/to/dir/file at the same time,
• while allowing a valid patch that removes a symbolic link path/to/dir and then adds a file path/to/dir/file.

That means, in that case, the error message won't be a generic one like "%s: patch does not apply", but a more specific one:

affected file '%s' is beyond a symbolic link

I suggest you take a look at tiny httpd. If you want to write it from scratch, then you'll want to thoroughly read RFC 2616. Use BSD sockets to access the network at a really low level.

Just make round(x-0.5) this will always return the next rounded down Integer value of your Float. You can also easily round up by do round(x+0.5)

The simplest validation is as follows:

<form name="ff1" method="post">
  <input type="email" name="email" id="fremail" placeholder="[email protected]" />
  <input type="text" pattern="[a-z0-9. -]+" title="Please enter only alphanumeric characters." name="title" id="frtitle" placeholder="Title" />
  <input type="url" name="url" id="frurl" placeholder="http://yourwebsite.com/" />
  <input type="submit" name="Submit" value="Continue" />
</form>

It uses HTML5 attributes (like as pattern).

JavaScript: none.

If you have tried everything in this post but are not having success getting PHP to work, this is what fixed it for my case:

Make sure you have these lines uncommented in /etc/php5/fpm/pool.d/www.conf:

listen.owner = www-data
listen.group = www-data
listen.mode = 0660

Make sure /etc/nginx/fastcgi_params looks like this:

fastcgi_param  QUERY_STRING       $query_string;
fastcgi_param  REQUEST_METHOD     $request_method;
fastcgi_param  CONTENT_TYPE       $content_type;
fastcgi_param  CONTENT_LENGTH     $content_length;

fastcgi_param  SCRIPT_NAME        $fastcgi_script_name;
fastcgi_param  REQUEST_URI        $request_uri;
fastcgi_param  DOCUMENT_URI       $document_uri;
fastcgi_param  DOCUMENT_ROOT      $document_root;
fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name;
fastcgi_param  SERVER_PROTOCOL    $server_protocol;
fastcgi_param  PATH_INFO          $fastcgi_script_name;
fastcgi_param  HTTPS              $https if_not_empty;

fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;
fastcgi_param  SERVER_SOFTWARE    nginx/$nginx_version;

fastcgi_param  REMOTE_ADDR        $remote_addr;
fastcgi_param  REMOTE_PORT        $remote_port;
fastcgi_param  SERVER_ADDR        $server_addr;
fastcgi_param  SERVER_PORT        $server_port;
fastcgi_param  SERVER_NAME        $server_name;

# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_param  REDIRECT_STATUS    200;

These two lines were missing from my /etc/nginx/fastcgi_params, make sure they are there!

fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name;
fastcgi_param  PATH_INFO          $fastcgi_script_name;

Then, restart php5-fpm and nginx. Should do the trick.

To test a scenario with a void method like

void testMeWell() throws SomeException {..}

to not throw an exception:

Junit5

assertDoesNotThrow(() -> {
    testMeWell();
});

Unlike languages that employ 'true' lexical scoping, Python opts to have specific 'namespaces' for variables, whether it be global, nonlocal, or local. It could be argued that making developers consciously code with such namespaces in mind is more explicit, thus more understandable. I would argue that such complexities make the language more unwieldy, but I guess it's all down to personal preference.

Here are some examples regarding global:-

>>> global_var = 5
>>> def fn():
...     print(global_var)
... 
>>> fn()
5
>>> def fn_2():
...     global_var += 2
...     print(global_var)
... 
>>> fn_2()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 2, in fn_2
UnboundLocalError: local variable 'global_var' referenced before assignment
>>> def fn_3():
...     global global_var
...     global_var += 2
...     print(global_var)
... 
>>> fn_3()
7

The same patterns can be applied to nonlocal variables too, but this keyword is only available to the latter Python versions.

In case you're wondering, nonlocal is used where a variable isn't global, but isn't within the function definition it's being used. For example, a def within a def, which is a common occurrence partially due to a lack of multi-statement lambdas. There's a hack to bypass the lack of this feature in the earlier Pythons though, I vaguely remember it involving the use of a single-element list...

Note that writing to variables is where these keywords are needed. Just reading from them isn't ambiguous, thus not needed. Unless you have inner defs using the same variable names as the outer ones, which just should just be avoided to be honest.

The only selector I see is a[id$="name"] (all links with id finishing by "name") but it's not as restrictive as it should.

Hmm, looks a little bizarre, try running it with the following annotation at the top of the class:

@RunWith(SpringJUnit4ClassRunner.class)
public class UserDaoTest {
}

and let me know how you get on with it.

Check that you have build automatically enabled as well. If you want to make sure your test classes are being compiled correctly clear out the Maven target folder (and any bin folder that Eclipse may be using). Are you using m2eclipse as well, as I find it to be a little problematic.

Declare them outside the subroutines, like this:

Public wbA as Workbook
Public wbB as Workbook
Sub MySubRoutine()
    Set wbA = Workbooks.Open("C:\file.xlsx")
    Set wbB = Workbooks.Open("C:\file2.xlsx")
    OtherSubRoutine
End Sub
Sub OtherSubRoutine()
    MsgBox wbA.Name, vbInformation
End Sub

Alternately, you can pass variables between subroutines:

Sub MySubRoutine()
Dim wbA as Workbook
Dim wbB as Workbook
    Set wbA = Workbooks.Open("C:\file.xlsx")
    Set wbB = Workbooks.Open("C:\file2.xlsx")
    OtherSubRoutine wbA, wbB
End Sub
Sub OtherSubRoutine(wb1 as Workbook, wb2 as Workbook)
    MsgBox wb1.Name, vbInformation
    MsgBox wb2.Name, vbInformation
End Sub

Or use Functions to return values:

Sub MySubroutine()
    Dim i as Long
    i = MyFunction()
    MsgBox i
End Sub
Function MyFunction()
    'Lots of code that does something
    Dim x As Integer, y as Double
    For x = 1 to 1000
        'Lots of code that does something
    Next
    MyFunction = y
End Function

In the second method, within the scope of OtherSubRoutine you refer to them by their parameter names wb1 and wb2. Passed variables do not need to use the same names, just the same variable types. This allows you some freedom, for example you have a loop over several workbooks, and you can send each workbook to a subroutine to perform some action on that Workbook, without making all (or any) of the variables public in scope.

A Note About User Forms

Personally I would recommend keeping Option Explicit in all of your modules and forms (this prevents you from instantiating variables with typos in their names, like lCoutn when you meant lCount etc., among other reasons).

If you're using Option Explicit (which you should), then you should qualify module-scoped variables for style and to avoid ambiguity, and you must qualify user-form Public scoped variables, as these are not "public" in the same sense. For instance, i is undefined, though it's Public in the scope of UserForm1:

You can refer to it as UserForm1.i to avoid the compile error, or since forms are New-able, you can create a variable object to contain reference to your form, and refer to it that way:

NB: In the above screenshots x is declared Public x as Long in another standard code module, and will not raise the compilation error. It may be preferable to refer to this as Module2.x to avoid ambiguity and possible shadowing in case you re-use variable names...

If you only have a single newline in the input, just doing

std::cin.ignore();

will work fine. It reads and discards the next character from the input.

But if you have anything else still in the input, besides the newline (for example, you read one word but the user entered two words), then you have to do

std::cin.ignore(std::numeric_limits<std::streamsize>::max(), '\n');

See e.g. this reference of the ignore function.

To be even more safe, do the second alternative above in a loop until gcount returns zero.

After several hours of testing and trying things...

I solved this problem as simple as possible. I notice that they use "test pages" inside Facebook Developers Page that contains only the "og" tags and some text in the body tag that referals this og tags.

So what have i done?

I created a second view in my application, containing this same things they use.

And how i know is Facebook that is accessing my page so i can change the view? They have a unique User Agent: "facebookexternalhit/1.1"

Just thought it might be useful to mention formatting as well in regards to timedelta. strptime() parses a string representing a time according to a format.

from datetime import datetime

datetimeFormat = '%Y/%m/%d %H:%M:%S.%f'    
time1 = '2016/03/16 10:01:28.585'
time2 = '2016/03/16 09:56:28.067'  
time_dif = datetime.strptime(time1, datetimeFormat) - datetime.strptime(time2,datetimeFormat)
print(time_dif)

This will output: 0:05:00.518000

If you have multiple checkboxes on the same form

The controller code

vm.doYouHaveCheckBox = ['aaa', 'ccc', 'bbb'];
vm.desiredRoutesCheckBox = ['ddd', 'ccc', 'Default'];
vm.doYouHaveCBSelection = [];
vm.desiredRoutesCBSelection = [];

View code

<div ng-repeat="doYouHaveOption in vm.doYouHaveCheckBox">
    <div class="action-checkbox">
        <input id="{{doYouHaveOption}}" type="checkbox" value="{{doYouHaveOption}}" ng-checked="vm.doYouHaveCBSelection.indexOf(doYouHaveOption) > -1" ng-click="vm.toggleSelection(doYouHaveOption,vm.doYouHaveCBSelection)" />
        <label for="{{doYouHaveOption}}"></label>
        {{doYouHaveOption}}
    </div>
</div>

<div ng-repeat="desiredRoutesOption in vm.desiredRoutesCheckBox">
     <div class="action-checkbox">
          <input id="{{desiredRoutesOption}}" type="checkbox" value="{{desiredRoutesOption}}" ng-checked="vm.desiredRoutesCBSelection.indexOf(desiredRoutesOption) > -1" ng-click="vm.toggleSelection(desiredRoutesOption,vm.desiredRoutesCBSelection)" />
          <label for="{{desiredRoutesOption}}"></label>
          {{desiredRoutesOption}}
     </div>
</div>        

I try to avoid floating elements unless the design really needs it. Because you have floated the <li> they are out of normal flow.

If you add .navigation { text-align:center; } and change .navigation li { float: left; } to .navigation li { display: inline-block; } then entire navigation will be centred.

One caveat to this approach is that display: inline-block; is not supported in IE6 and needs a workaround to make it work in IE7.

Adding scroll="no" and style="overflow:hidden" on iframe didn't work, I had to add style="overflow:hidden" on body of html document loaded inside iframe.

You can set a custom toolbar item color dynamically by creating a custom toolbar class:

                //Step 2: Changing the color of any ActionMenuViews - icons that

                            ((ActionMenuItemView) innerView).getCompoundDrawables()[finalK].setColorFilter(colorFilter);

                    }
                }
            }
        }
    }



}

then refer to it in your layout file. Now you can set a custom color using

toolbar.setItemColor(Color.Red);

I found the information to do this here: How to dynamicaly change Android Toolbar icons color

and then I edited it, improved upon it, and posted it here: GitHub:AndroidDynamicToolbarItemColor

The ENOSPC ("No space left on device") error will be triggered in any situation in which the data or the metadata associated with an I/O operation can't be written down anywhere because of lack of space. This doesn't always mean disk space – it could mean physical disk space, logical space (e.g. maximum file length), space in a certain data structure or address space. For example you can get it if there isn't space in the directory table (vfat) or there aren't any inodes left. It roughly means “I can't find where to write this down”.

Particularly in Python, this can happen on any write I/O operation. It can happen during f.write, but it can also happen on open, on f.flush and even on f.close. Where it happened provides a vital clue for the reason that it did – if it happened on open there wasn't enough space to write the metadata for the entry, if it happened during f.write, f.flush or f.close there wasn't enough disk space left or you've exceeded the maximum file size.

If the filesystem in the given directory is vfat you'd hit the maximum file limit at about the same time that you did. The limit is supposed to be 2^16 directory entries, but if I recall correctly some other factors can affect it (e.g. some files require more than one entry).

It would be best to avoid creating so many files in a directory. Few filesystems handle so many directory entries with ease. Unless you're certain that your filesystem deals well with many files in a directory, you can consider another strategy (e.g. create more directories).

P.S. Also do not trust the remaining disk space – some file systems reserve some space for root and others miscalculate the free space and give you a number that just isn't true.

The size of the numerical types is not defined in the C++ standard, although the minimum sizes are. The way to tell what size they are on your platform is to use numeric limits

For example, the maximum value for a int can be found by:

std::numeric_limits<int>::max();

Computers don't work in base 10, which means that the maximum value will be in the form of 2ⁿ-1 because of how the numbers of represent in memory. Take for example eight bits (1 byte)

  0100 1000

The right most bit (number) when set to 1 represents 2⁰, the next bit 2¹, then 2² and so on until we get to the left most bit which if the number is unsigned represents 2⁷.

So the number represents 2⁶ + 2³ = 64 + 8 = 72, because the 4th bit from the right and the 7th bit right the left are set.

If we set all values to 1:

11111111

The number is now (assuming unsigned)
128 + 64 + 32 + 16 + 8 + 4 + 2 + 1 = 255 = 2⁸ - 1
And as we can see, that is the largest possible value that can be represented with 8 bits.

On my machine and int and a long are the same, each able to hold between -2³¹ to 2³¹ - 1. In my experience the most common size on modern 32 bit desktop machine.

Update

As of jQuery 3.0, the new syntax is just .on:

see this answer here and the code:

$('iframe').on('load', function() {
    // do stuff 
});

I would use:

\([^)]*\)

The problem is in this line:

with pattern.findall(row) as f:

You are using the with statement. It requires an object with __enter__ and __exit__ methods. But pattern.findall returns a list, with tries to store the __exit__ method, but it can't find it, and raises an error. Just use

f = pattern.findall(row)

instead.

C++11 standard on == for std::vector

Others have mentioned that operator== does compare vector contents and works, but here is a quote from the C++11 N3337 standard draft which I believe implies that.

We first look at Chapter 23.2.1 "General container requirements", which documents things that must be valid for all containers, including therefore std::vector.

That section Table 96 "Container requirements" which contains an entry:

Expression   Operational semantics
===========  ======================
a == b       distance(a.begin(), a.end()) == distance(b.begin(), b.end()) &&
             equal(a.begin(), a.end(), b.begin())

The distance part of the semantics means that the size of both containers are the same, but stated in a generalized iterator friendly way for non random access addressable containers. distance() is defined at 24.4.4 "Iterator operations".

Then the key question is what does equal() mean. At the end of the table we see:

Notes: the algorithm equal() is defined in Clause 25.

and in section 25.2.11 "Equal" we find its definition:

template<class InputIterator1, class InputIterator2>
bool equal(InputIterator1 first1, InputIterator1 last1,
           InputIterator2 first2);

template<class InputIterator1, class InputIterator2,
class BinaryPredicate>
bool equal(InputIterator1 first1, InputIterator1 last1,
           InputIterator2 first2, BinaryPredicate pred);

1 Returns: true if for every iterator i in the range [first1,last1) the following corresponding conditions hold: *i == *(first2 + (i - first1)), pred(*i, *(first2 + (i - first1))) != false. Otherwise, returns false.

In our case, we care about the overloaded version without BinaryPredicate version, which corresponds to the first pseudo code definition *i == *(first2 + (i - first1)), which we see is just an iterator-friendly definition of "all iterated items are the same".

Similar questions for other containers:

• how to compare two std::set?

for example on debian

sudo gpasswd -a svn-admin www-data
sudo chgrp -R www-data svn/
sudo chmod -R g=rwsx svn/

If you don't give any position to parent then by default it takes static. If you want to understand that difference refer to this example

Example 1::

http://jsfiddle.net/Cr9KB/1/

   #mainall
{

    background-color:red;
    height:150px;
    overflow:scroll
}

Here parent class has no position so element is placed according to body.

Example 2::

http://jsfiddle.net/Cr9KB/2/

#mainall
{
    position:relative;
    background-color:red;
    height:150px;
    overflow:scroll
}

In this example parent has relative position hence element are positioned absolute inside relative parent.

Taking other answers into account, i came up with my own: Try this :

SUBSTRING('your-string-here', PATINDEX('%[0-9]%', 'your-string-here'), LEN('your-string-here'))

NB: Only works for the first int in the string, ex: abc123vfg34 returns 123.

As someone already pointed out how to do this with .Net Core, if your header contains a "-" or some other character .Net disallows, you can do something like:

public string Test([FromHeader]string host, [FromHeader(Name = "Content-Type")] string contentType)
{
}

Your function worked for me after changing its declaration to this ...

Function processArr(Arr As Variant) As String

You could also consider a ParamArray like this ...

Function processArr(ParamArray Arr() As Variant) As String
    'Dim N As Variant
    Dim N As Long
    Dim finalStr As String
    For N = LBound(Arr) To UBound(Arr)
        finalStr = finalStr & Arr(N)
    Next N
    processArr = finalStr
End Function

And then call the function like this ...

processArr("foo", "bar")

I had this problem just now, using an SQLite database on a remote server, stored on an NFS mount. SQLite was unable to obtain a lock after the remote shell session I used had crashed while the database was open.

The recipes for recovery suggested above did not work for me (including the idea to first move and then copy the database back). But after copying it to a non-NFS system, the database became usable and not data appears to have been lost.

To read json response use json.loads(). Here is the sample.

import json
import urllib
import urllib2

post_params = {
    'foo' : bar
}

params = urllib.urlencode(post_params)
response = urllib2.urlopen(url, params)
json_response = json.loads(response.read())

import numpy as np
import scipy.stats


def mean_confidence_interval(data, confidence=0.95):
    a = 1.0 * np.array(data)
    n = len(a)
    m, se = np.mean(a), scipy.stats.sem(a)
    h = se * scipy.stats.t.ppf((1 + confidence) / 2., n-1)
    return m, m-h, m+h

you can calculate like this way.

If your host is using suPHP, you can try creating a php.ini file in the same folder as the script and adding:

allow_url_fopen = On

(you can determine this by creating a file and checking which user it was created under: if you, it's suPHP, if "apache/nobody" or not you, then it's a normal PHP mode. You can also make a script

<?php
echo `id`;
?>

To give the same information, assuming shell_exec is not a disabled function)

ssh user@machine python < script.py - arg1 arg2

Because cat | is usually not necessary

For future reference, I ran into a similar problem; I was creating too many file descriptors (FDs) by creating too many files and sockets (on Unix OSs, everything is a FD). My solution was to increase FDs at runtime with setrlimit().

First I got the FD limits, with the following code:

// This goes somewhere in your code
struct rlimit rlim;

if (getrlimit(RLIMIT_NOFILE, &rlim) == 0) {
    std::cout << "Soft limit: " << rlim.rlim_cur << std::endl;
    std::cout << "Hard limit: " << rlim.rlim_max << std::endl;
} else {
    std::cout << "Unable to get file descriptor limits" << std::endl;

After running getrlimit(), I could confirm that on my system, the soft limit is 256 FDs, and the hard limit is infinite FDs (this is different depending on your distro and specs). Since I was creating > 300 FDs between files and sockets, my code was crashing.

In my case I couldn't decrease the number of FDs, so I decided to increase the FD soft limit instead, with this code:

// This goes somewhere in your code
struct rlimit rlim;

rlim.rlim_cur = NEW_SOFT_LIMIT;
rlim.rlim_max = NEW_HARD_LIMIT;

if (setrlimit(RLIMIT_NOFILE, &rlim) == -1) {
    std::cout << "Unable to set file descriptor limits" << std::endl;
}

Note that you can also get the number of FDs that you are using, and the source of these FDs, with this code.

Also you can find more information on gettrlimit() and setrlimit() here and here.

This is only for those who haven't done 'mobile-first' design to their websites yet and looking for a quick temporary solution.

You can do this type of checking with Flash or Silverlight but not Javascript. The javascript sandbox does not allow access to the file system. The size check would need to be done server side after it has been uploaded.

If you want to go the Silverlight/Flash route, you could check that if they are not installed to default to a regular file upload handler that uses the normal controls. This way, if the do have Silverlight/Flash installed their experience will be a bit more rich.

Its pretty simple. Assume that your classname is Car and the namespace is Vehicles, then pass the parameter as Vehicles.Car which returns object of type Car. Like this you can create any instance of any class dynamically.

public object GetInstance(string strFullyQualifiedName)
{         
     Type t = Type.GetType(strFullyQualifiedName); 
     return  Activator.CreateInstance(t);         
}

If your Fully Qualified Name(ie, Vehicles.Car in this case) is in another assembly, the Type.GetType will be null. In such cases, you have loop through all assemblies and find the Type. For that you can use the below code

public object GetInstance(string strFullyQualifiedName)
{
     Type type = Type.GetType(strFullyQualifiedName);
     if (type != null)
         return Activator.CreateInstance(type);
     foreach (var asm in AppDomain.CurrentDomain.GetAssemblies())
     {
         type = asm.GetType(strFullyQualifiedName);
         if (type != null)
             return Activator.CreateInstance(type);
     }
     return null;
 }

Now if you want to call a parameterized constructor do the following

Activator.CreateInstance(t,17); // Incase you are calling a constructor of int type

instead of

Activator.CreateInstance(t);

This is similar to many of the other suggestions with a couple enhancements:

• No need to hardcode the domain (works with vhosts that accept multiple domains or between environments)
• Preserves the scheme (http/https) and ignores the effects of previous %{REQUEST_URI} rules.

• The path portion not affected by previous RewriteRules like %{REQUEST_URI} is.

  RewriteCond %{HTTP_HOST} !^www\. [NC]
  RewriteRule ^(.*)$ %{REQUEST_SCHEME}://www.%{HTTP_HOST}/$1 [R=301,L]
  

$subscription_key  ='';
    $host = '';    
    $request_headers = array(
                    "X-Mashape-Key:" . $subscription_key,
                    "X-Mashape-Host:" . $host
                );

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_HTTPHEADER, $request_headers);

    $season_data = curl_exec($ch);

    if (curl_errno($ch)) {
        print "Error: " . curl_error($ch);
        exit();
    }

    // Show me the result
    curl_close($ch);
    $json= json_decode($season_data, true);

if your signal is in the matrix X, you make it zero-mean by removing the average:

X=X-mean(X(:));

and unit variance by dividing by the standard deviation:

X=X/std(X(:));

in your PHP file, when you echo your data use json_encode (http://php.net/manual/en/function.json-encode.php)

e.g.

<?php
//plum or data...
$output = array("data","plum");

echo json_encode($output);

?>

in your javascript code, when your ajax completes the json encoded response data can be turned into an js array like this:

 $.ajax({
                type: "POST",
                url: "process.php",
                data: somedata;
                success function(json_data){
                    var data_array = $.parseJSON(json_data);

                    //access your data like this:
                    var plum_or_whatever = data_array['output'];.
                    //continue from here...
                }
            });

You got half of the answer! Now that you created the event handler, you need to hook it to the form so that it actually gets called when the form is loading. You can achieve that by doing the following:

 public class ProgramViwer : Form{
  public ProgramViwer()
  {
       InitializeComponent();
       Load += new EventHandler(ProgramViwer_Load);
  }
  private void ProgramViwer_Load(object sender, System.EventArgs e)
  {
       formPanel.Controls.Clear();
       formPanel.Controls.Add(wel);
  }
}

In my case, I had an invalid package name. I wasn't able to pick up on the error code right away, because I didn't scroll up far enough, but the error was:

remote:        $ NPM_CONFIG_PRODUCTION=false npm install --prefix client && npm run build --prefix client
remote: npm ERR! code EINVALIDPACKAGENAME // <-- this was hard to find
remote: npm ERR! Invalid package name "react-loader-spinne  r": name can only contain URL-friendly characters

For a simple way, use system():

#include <stdlib.h>
...
int status = system("./foo 1 2 3");

system() will wait for foo to complete execution, then return a status variable which you can use to check e.g. exitcode (the command's exitcode gets multiplied by 256, so divide system()'s return value by that to get the actual exitcode: int exitcode = status / 256).

The manpage for wait() (in section 2, man 2 wait on your Linux system) lists the various macros you can use to examine the status, the most interesting ones would be WIFEXITED and WEXITSTATUS.

Alternatively, if you need to read foo's standard output, use popen(3), which returns a file pointer (FILE *); interacting with the command's standard input/output is then the same as reading from or writing to a file.

function get(path) {
    var form = document.createElement("form");
    form.setAttribute("method", "get");
    form.setAttribute("action", path);
    document.body.appendChild(form);
    form.submit();
}


get('/my/url/')

Same thing can be done for post request as well.
Have a look at this link JavaScript post request like a form submit

No need to uninstall anything, you can just delete the eclipse/ folder, but you should also use a fresh workspace or delete the workspace/.metadata folder.

Edit - Contained User (v12 and later)

As of Sql Azure 12, databases will be created as Contained Databases which will allow users to be created directly in your database, without the need for a server login via master.

CREATE USER [MyUser] WITH PASSWORD = 'Secret';
ALTER ROLE [db_datareader] ADD MEMBER [MyUser];

Note when connecting to the database when using a contained user that you must always specify the database in the connection string.

Traditional Server Login - Database User (Pre v 12)

Just to add to @Igorek's answer, you can do the following in Sql Server Management Studio:

Create the new Login on the server
In master (via the Available databases drop down in SSMS - this is because USE master doesn't work in Azure):

create the login:

CREATE LOGIN username WITH password='password';

Create the new User in the database
Switch to the actual database (again via the available databases drop down, or a new connection)

CREATE USER username FROM LOGIN username;

(I've assumed that you want the user and logins to tie up as username, but change if this isn't the case.)

Now add the user to the relevant security roles

EXEC sp_addrolemember N'db_owner', N'username'
GO

(Obviously an app user should have less privileges than dbo.)

This article by Atul Gupta has sample code that covers several scenarios:

1. Regular resource image binding to Source property in XAML
2. Binding resource image, but from code behind
3. Binding resource image in code behind by using Application.GetResourceStream
4. Loading image from file path via memory stream (same is applicable when loading blog image data from database)
5. Loading image from file path, but by using binding to a file path Property
6. Binding image data to a user control which internally has image control via dependency property
7. Same as point 5, but also ensuring that the file doesn't get's locked on hard-disk

After changed API version 9.0 getting the error Cleartext HTTP traffic to YOUR-API.DOMAIN.COM not permitted (targetSdkVersion="28"). in xamarin, xamarin.android and android studio.

Two steps to solve this error in xamarin, xamarin.android and android studio.

Step 1: Create file resources/xml/network_security_config.xml

In network_security_config.xml

<?xml version="1.0" encoding="utf-8" ?>
<network-security-config>
  <domain-config cleartextTrafficPermitted="true">
    <domain includeSubdomains="true">mobapi.3detrack.in</domain>
  </domain-config>
</network-security-config>

Step 2: update AndroidManifest.xml -

Add android:networkSecurityConfig="@xml/network_security_config" on application tag. e.g:

<application android:label="your App Name" android:icon="@drawable/icon" android:networkSecurityConfig="@xml/network_security_config">

If you got white space in your branch then you will get this error.

One option for the follow on question (how to find a customer who might have any number of first names):

List<string> names = new List<string>{ "John", "Max", "Pete" };
bool has = customers.Any(cus => names.Contains(cus.FirstName));

or to retrieve the customer from csv of similar list

string input = "John,Max,Pete";
List<string> names = input.Split(',').ToList();
customer = customers.FirstOrDefault(cus => names.Contains(cus.FirstName));

I have a complicated Web App and I couldn't figure out exactly why this error was being thrown. It was causing the JavaScript to abort when thrown.

In select2.js I changed:

        if (typeof(opts.query) !== "function") {
            throw "query function not defined for Select2 " + opts.element.attr("id");
        }

to:

        if (typeof(opts.query) !== "function") {
            console.error("query function not defined for Select2 " + opts.element.attr("id"));
        }

Now everything seems to work properly but it is still logging in error in case I want to try and figure out what exactly in my code is causing the error. But for now this is a good enough fix for me.

I've been searching for hours and no one could help me. I did a simple thing to solve this problem. (WINDOWS 10 x64)

Follow this:

1 - Go to your php_mysqli.dll path (in my case: C:/xampp/php/ext);

2 - Move the php_mysqli.dll to the previous folder (C:/xampp/php);

3 - Open php.ini and search the line: "extension: php_mysqli.dll";

4 - Change to the path where is your file: extension="C:\xampp\php\php_mysqli.dll";

5 - Restart your application (wampp, xampp, etc.) and start Apache Server;

The problem was the path ext/php_mysqli.dll, I've tried changing the line to extension="C:\xampp\php\ext\php_mysqli.dll" but doesn't worked.

This was a real issue for me, and quite a sneaky problem to try and remedy...

The problem I had was that a module that was installed on my WiFi adapter was conflicting with the Microsoft Virtual Adapter (or whatever it's actually called).

To fix it:

1. Hold the Windows Key + Push R
2. Type: ncpa.cpl in to the box, and hit OK.
3. Identify the network adapter you want to use for the hostednetwork, right-click it, and select Properties.
4. You'll see a big box in the middle of the properties window, under the heading The connection uses the following items:. Look down the list for anything that seems out of the ordinary, and uncheck it. Hit OK.
5. Try running the netsh wlan start hostednetwork command again.
6. Repeat steps 4 and 5 as necessary.

In my case my adapter was running a module called SoftEther Lightweight Network Protocol, which I believe is used to help connect to VPN Gate VPN servers via the SoftEther software.

If literally nothing else works, then I'd suspect something similar to the problem I encountered, namely that a module on your network adapter is interfering with the hostednetwork aspect of your driver.

Check this:

hello.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View paramView) {
        text.setText("hello");
    }
});

You can do like this:

$q="SELECT * FROM projects WHERE Year(Date) = '$year' and Month(Date) = '$month'";

Maybe this will help others in the future - I had the same error while trying to multiple a float and a list of floats. The thing is that everyone here talked about multiplying a float with a string (but here all my element were floats all along) so the problem was actually using the * operator on a list.

For example:

import math
import numpy as np
alpha = 0.2 
beta=1-alpha
C = (-math.log(1-beta))/alpha

coff = [0.0,0.01,0.0,0.35,0.98,0.001,0.0]
coff *= C

The error:

    coff *= C 
TypeError: can't multiply sequence by non-int of type 'float'

The solution - convert the list to numpy array:

coff = np.asarray(coff) * C

It involves eyeballing it (well I suppose you could get out a calculator and calculate) but just insert said control on the form and then remove any anchoring (anchor = None).

import numpy as np
x=np.array([6,3,5,2,1,4,9,7,8])
y=np.array([2,1,3,5,3,9,8,10,7])
sortId=np.argsort(x)
x=x[sortId]
y=y[sortId]
minm = np.array([])
maxm = np.array([])
i = 0
while i < length-1:
    if i < length - 1:
        while i < length-1 and y[i+1] >= y[i]:
            i+=1

        if i != 0 and i < length-1:
            maxm = np.append(maxm,i)

        i+=1

    if i < length - 1:
        while i < length-1 and y[i+1] <= y[i]:
            i+=1

        if i < length-1:
            minm = np.append(minm,i)
        i+=1


print minm
print maxm

minm and maxm contain indices of minima and maxima, respectively. For a huge data set, it will give lots of maximas/minimas so in that case smooth the curve first and then apply this algorithm.

I tweaked your code a bit and made it more robust. In terms of progressive enhancement it's probaly better to have all the fade-in-out logic in JavaScript. In the example of myfunksyde any user without JavaScript sees nothing because of the opacity: 0;.

    $(window).on("load",function() {
    function fade() {
        var animation_height = $(window).innerHeight() * 0.25;
        var ratio = Math.round( (1 / animation_height) * 10000 ) / 10000;

        $('.fade').each(function() {

            var objectTop = $(this).offset().top;
            var windowBottom = $(window).scrollTop() + $(window).innerHeight();

            if ( objectTop < windowBottom ) {
                if ( objectTop < windowBottom - animation_height ) {
                    $(this).html( 'fully visible' );
                    $(this).css( {
                        transition: 'opacity 0.1s linear',
                        opacity: 1
                    } );

                } else {
                    $(this).html( 'fading in/out' );
                    $(this).css( {
                        transition: 'opacity 0.25s linear',
                        opacity: (windowBottom - objectTop) * ratio
                    } );
                }
            } else {
                $(this).html( 'not visible' );
                $(this).css( 'opacity', 0 );
            }
        });
    }
    $('.fade').css( 'opacity', 0 );
    fade();
    $(window).scroll(function() {fade();});
});

You may have as many levels of Object hierarchy as you want, as long you declare an Object as being a property of another parent Object. Pay attention to the commas on each level, that's the tricky part. Don't use commas after the last element on each level:

{el1, el2, {el31, el32, el33}, {el41, el42}}

var MainObj = {_x000D_
_x000D_
  prop1: "prop1MainObj",_x000D_
  _x000D_
  Obj1: {_x000D_
    prop1: "prop1Obj1",_x000D_
    prop2: "prop2Obj1",    _x000D_
    Obj2: {_x000D_
      prop1: "hey you",_x000D_
      prop2: "prop2Obj2"_x000D_
    }_x000D_
  },_x000D_
    _x000D_
  Obj3: {_x000D_
    prop1: "prop1Obj3",_x000D_
    prop2: "prop2Obj3"_x000D_
  },_x000D_
  _x000D_
  Obj4: {_x000D_
    prop1: true,_x000D_
    prop2: 3_x000D_
  }  _x000D_
};_x000D_
_x000D_
console.log(MainObj.Obj1.Obj2.prop1);

If you get the the text inside the element use

Text()

$(".element-classname").text();

In your code:

$('.HOEnZb').text();

if you want get all the data including html Tags use:

html()

 $(".element-classname").html();

In your code:

$('.HOEnZb').html();

Hope it helps:)

Maybe something like this:

import matplotlib.pyplot
import pylab

x = [1,2,3,4]
y = [3,4,8,6]

matplotlib.pyplot.scatter(x,y)

matplotlib.pyplot.show()

EDIT:

Let me see if I understand you correctly now:

You have:

       test1 | test2 | test3
test3 |   1   |   0  |  1

test4 |   0   |   1  |  0

test5 |   1   |   1  |  0

Now you want to represent the above values in in a scatter plot, such that value of 1 is represented by a dot.

Let's say you results are stored in a 2-D list:

results = [[1, 0, 1], [0, 1, 0], [1, 1, 0]]

We want to transform them into two variables so we are able to plot them.

And I believe this code will give you what you are looking for:

import matplotlib
import pylab


results = [[1, 0, 1], [0, 1, 0], [1, 1, 0]]

x = []
y = []

for ind_1, sublist in enumerate(results):
    for ind_2, ele in enumerate(sublist):
        if ele == 1:
            x.append(ind_1)
            y.append(ind_2)       


matplotlib.pyplot.scatter(x,y)

matplotlib.pyplot.show()

Notice that I do need to import pylab, and you would have play around with the axis labels. Also this feels like a work around, and there might be (probably is) a direct method to do this.

I basically do like this, create new element and attach that to <head>

var x = document.createElement('script');
x.src = 'http://example.com/test.js';
document.getElementsByTagName("head")[0].appendChild(x);

You may also use onload event to each script you attach, but please test it out, I am not so sure it works cross-browser or not.

x.onload=callback_function;

You have a few typos in your select. It should be: input:not([disabled]):not([type="submit"]):focus

See this jsFiddle for a proof of concept. On a sidenote, if I removed the "background-color" property, then the box shadow no longer works. Not sure why.

As Alex says, it works very well. The only tricky part is to remember to make any changes in the cmake files, rather than from within Visual Studio. So on all platforms, the workflow is similar to if you'd used plain old makefiles.

But it's fairly easy to work with, and I've had no issues with cmake generating invalid files or anything like that, so I wouldn't worry too much.

try:

$("td[id^=" + value + "]")

Here's a method that I just wrote today, so that I can pass as many message boxes to the page as I want to:

/// <summary>
/// Shows a basic MessageBox on the passed in page
/// </summary>
/// <param name="page">The Page object to show the message on</param>
/// <param name="message">The message to show</param>
/// <returns></returns>
public static ShowMessageBox(Page page, string message)
{
    Type cstype = page.GetType();

    // Get a ClientScriptManager reference from the Page class.
    ClientScriptManager cs = page.ClientScript;

    // Find the first unregistered script number
    int ScriptNumber = 0;
    bool ScriptRegistered = false;
    do
    {
        ScriptNumber++;
        ScriptRegistered = cs.IsStartupScriptRegistered(cstype, "PopupScript" + ScriptNumber);
    } while (ScriptRegistered == true);

    //Execute the new script number that we found
    cs.RegisterStartupScript(cstype, "PopupScript" + ScriptNumber, "alert('" + message + "');", true);
}

I don't believe the currently accepted answer is correct. For example, I have the following .htaccess file in the root of a virtual server (apache 2.4):

<Files "reminder.php">
require all denied
require host localhost
require ip 127.0.0.1
require ip xxx.yyy.zzz.aaa
</Files>

This prevents external access to reminder.php which is in a subdirectory. I have a similar .htaccess file on my Apache 2.2 server with the same effect:

<Files "reminder.php">
        Order Deny,Allow
        Deny from all
        Allow from localhost
        Allow from 127.0.0.1
     Allow from xxx.yyy.zzz.aaa
</Files>

I don't know for sure but I suspect it's the attempt to define the subdirectory specifically in the .htaccess file, viz <Files ./inscription/log.txt> which is causing it to fail. It would be simpler to put the .htaccess file in the same directory as log.txt i.e. in the inscription directory and it will work there.

Setup a DocumentListener on nameField. When nameField is updated, update your label.

What about opacity

#mybox:hover {
    opacity: 0;
}

I think there are 2 things that add confusion to this topic:

1. statistical v.s. signal processing definition: as others have pointed out, in statistics we normalize auto-correlation into [-1,1].
2. partial v.s. non-partial mean/variance: when the timeseries shifts at a lag>0, their overlap size will always < original length. Do we use the mean and std of the original (non-partial), or always compute a new mean and std using the ever changing overlap (partial) makes a difference. (There's probably a formal term for this, but I'm gonna use "partial" for now).

I've created 5 functions that compute auto-correlation of a 1d array, with partial v.s. non-partial distinctions. Some use formula from statistics, some use correlate in the signal processing sense, which can also be done via FFT. But all results are auto-correlations in the statistics definition, so they illustrate how they are linked to each other. Code below:

import numpy
import matplotlib.pyplot as plt

def autocorr1(x,lags):
    '''numpy.corrcoef, partial'''

    corr=[1. if l==0 else numpy.corrcoef(x[l:],x[:-l])[0][1] for l in lags]

Here is the output figure:

We don't see all 5 lines because 3 of them overlap (at the purple). The overlaps are all non-partial auto-correlations. This is because computations from the signal processing methods (np.correlate, FFT) don't compute a different mean/std for each overlap.

Also note that the fft, no padding, non-partial (red line) result is different, because it didn't pad the timeseries with 0s before doing FFT, so it's circular FFT. I can't explain in detail why, that's what I learned from elsewhere.

Just use the following sql, you are done:

SELECT replace(CustomerName,' ', '') FROM Customers;

you can test this sample over here: W3School

You have not defined the variable input_line.

Add this:

string input_line;

And add this include.

#include <string>

Here is the full example. I also removed the semi-colon after the while loop, and you should have getline inside the while to properly detect the end of the stream.

#include <iostream>
#include <string>

int main() {
    for (std::string line; std::getline(std::cin, line);) {
        std::cout << line << std::endl;
    }
    return 0;
}

The _t data types are typedef types in the stdint.h header, while int is an in built fundamental data type. This make the _t available only if stdint.h exists. int on the other hand is guaranteed to exist.

My favorite version is the inline version:

${"variableName"} = 12;

$className->{"propertyName"};
$className->{"methodName"}();

StaticClass::${"propertyName"};
StaticClass::{"methodName"}();

You can place variables or expressions inside the brackets too!

ngOnInit() is called after ngOnChanges() was called the first time. ngOnChanges() is called every time inputs are updated by change detection.

ngAfterViewInit() is called after the view is initially rendered. This is why @ViewChild() depends on it. You can't access view members before they are rendered.

$('.close').click(function() {
  //Code to be executed when close is clicked
  $('#result').html('yes,result');
});

In case of Debug Running

~/Library/Developer/Xcode/DerivedData/{your app}/Build/Products/Debug/{Project Name}.app/Contents/MacOS

You can find standalone executable file(Mach-O 64-bit executable x86_64)

I would use

WHERE columnName LIKE '%[%]%'

SQL Server stores string summary statistics for use in estimating the number of rows that will match a LIKE clause. The cardinality estimates can be better and lead to a more appropriate plan when the square bracket syntax is used.

The response to this Connect Item states

We do not have support for precise cardinality estimation in the presence of user defined escape characters. So we probably get a poor estimate and a poor plan. We'll consider addressing this issue in a future release.

An example

CREATE TABLE T
(
X VARCHAR(50),
Y CHAR(2000) NULL
)

CREATE NONCLUSTERED INDEX IX ON T(X)

INSERT INTO T (X)
SELECT TOP (5) '10% off'
FROM master..spt_values
UNION ALL
SELECT  TOP (100000)  'blah'
FROM master..spt_values v1,  master..spt_values v2


SET STATISTICS IO ON;
SELECT *
FROM T 
WHERE X LIKE '%[%]%'

SELECT *
FROM T
WHERE X LIKE '%\%%' ESCAPE '\'

Shows 457 logical reads for the first query and 33,335 for the second.

In my case, I wanted to split a data frame in Train, test and dev with a specific number. Here I am sharing my solution

First, assign a unique id to a dataframe (if already not exist)

import uuid
df['id'] = [uuid.uuid4() for i in range(len(df))]

Here are my split numbers:

train = 120765
test  = 4134
dev   = 2816

The split function

def df_split(df, n):
    
    first  = df.sample(n)
    second = df[~df.id.isin(list(first['id']))]
    first.reset_index(drop=True, inplace = True)
    second.reset_index(drop=True, inplace = True)
    return first, second

Now splitting into train, test, dev

train, test = df_split(df, 120765)
test, dev   = df_split(test, 4134)

Your program has no knowledge of where your VS project is, so see get path for my .exe and go ../.. to get your project's path.

I solved the issue by adding https binding in my IIS websites and adding 443 SSL port and selecting a self signed certificate in binding.

You could also organise them into modules. So it would be something like.

./
controllers
    index.js
    indexController.js
app.js

and then in the indexController.js of the controllers export your controllers.

//indexController.js
module.exports = function(){
//do some set up

var self = {
     indexAction : function (req,res){
       //do your thing
}
return self;
};

then in index.js of controllers dir

exports.indexController = require("./indexController");

and finally in app.js

var controllers = require("./controllers");

app.get("/",controllers.indexController().indexAction);

I think this approach allows for clearer seperation and also you can configure your controllers by passing perhaps a db connection in.

You have encoding problem with your sourcecode file. It is maybe ISO-8859-1 encoded, but the compiler was set to use UTF-8. This will results in errors when using characters, which will not have the same bytes representation in UTF-8 and ISO-8859-1. This will happen to all characters which are not part of ASCII, for example ¬ NOT SIGN.

You can simulate this with the following program. It just uses your line of source code and generates a ISO-8859-1 byte array and decode this "wrong" with UTF-8 encoding. You can see at which position the line gets corrupted. I added 2 spaces at your source code to fit position 74 to fit this to ¬ NOT SIGN, which is the only character, which will generate different bytes in ISO-8859-1 encoding and UTF-8 encoding. I guess this will match indentation with the real source file.

 String reg = "      String reg = \"^(?=.*[0-9])(?=.*[a-z])(?=.*[A-Z])(?=.*[~#;:?/@&!\"'%*=¬.,-])(?=[^\\s]+$).{8,24}$\";";
 String corrupt=new String(reg.getBytes("ISO-8859-1"),"UTF-8");
 System.out.println(corrupt+": "+corrupt.charAt(74));
 System.out.println(reg+": "+reg.charAt(74));     

which results in the following output (messed up because of markup):

String reg = "^(?=.[0-9])(?=.[a-z])(?=.[A-Z])(?=.[~#;:?/@&!"'%*=?.,-])(?=[^\s]+$).{8,24}$";: ?

String reg = "^(?=.[0-9])(?=.[a-z])(?=.[A-Z])(?=.[~#;:?/@&!"'%*=¬.,-])(?=[^\s]+$).{8,24}$";: ¬

See "live" at https://ideone.com/ShZnB

To fix this, save the source files with UTF-8 encoding.

Open a terminal and run these commands:

cd /usr/local/cuda/samples/1_Utilities/deviceQuery
sudo make
./deviceQuery

You can get the information of CUDA Driver version, CUDA Runtime Version, and also detailed information for GPU(s). An image example of the output from my end is as below.

You can find the image here.

for me I simply had to add configure my git username and email with the following commands:

git config --global user.email "[email protected]"
git config --global user.name "Your Name"

Sounds like you're just trying to do a classic two-column lookup. http://www.dailydoseofexcel.com/archives/2009/04/21/vlookup-on-two-columns/

Tons of solutions for this, most simple is probably the following (which doesn't require an array formula):

=SUMPRODUCT((Lookup!A:A=Param!A1)*(Lookup!B:B=Param!B1)*(Lookup!C:C))

To translate your specific example, you would use:

=SUMPRODUCT((A1:A3=A2)*(B1:B3="B")*(C1:C3))

There is an excellent answer from Orwellophile, which does include a pure bash option (function rawurlencode), which I've used on my website (shell based CGI script, large number of URLS in response to search requests). The only draw back was high CPU during peak time.

I've found a modified solution, leverage bash "global replace" feature. With this solution processing time for url encode is 4X faster. The solution identify the characters to be escaped, and uses the "global replace" operator (${var//source/replacement}) to process all substitutions. The speed up is clearly from using bash internal loops, over explicit loop.

Performance: On core i3-8100 3.60Ghz. Test case: 1000 URL from stack overflow, similar to this ticket: "https://stackoverflow.com/questions/296536/how-to-urlencode-data-for-curl-command".

• Existing Solution: 0.807 sec
• Optimized Solution: 0.162 sec (5X speedup)

url_encode()
{
    local key="${1}" varname="${2:-_rval}" prefix="${3:-_ENCKEY_}"
    local unsafe=${key//[-_.~a-zA-Z0-9 ]/} 
    local -i key_len=${#unsafe}
    local ch ch1 ch0

    while [ "$unsafe" ] ;do
        ch=${unsafe:0:1}
        ch0="\\$ch"
        printf -v ch1 '%%%02x' "'$ch'" 
        key=${key//$ch0/"$ch1"}
        unsafe=${unsafe//"$ch0"}
    done
    key=${key// /+} 

    REPLY="$key"
    # printf "%s" "$REPLY"
    return 0
}

As a minor extra, it uses '+' to encode the space. Slightly more compact URL.

Benchmark:

function t {
    local key
    for (( i=1 ; i<=$1 ; i++ )) do url_encode "$2" kkk2 ; done
    echo "K=$REPLY"
}

First of all, why would you need to output to console in a release mode build? Nobody will think to look there when there's a gui...

Second, qDebug is fancy :)

Third, you can try adding console to your .pro's CONFIG, it might work.

This is how I make forms full screen.

private void button1_Click(object sender, EventArgs e)
{
    int minx, miny, maxx, maxy;
    inx = miny = int.MaxValue;
    maxx = maxy = int.MinValue;

    foreach (Screen screen in Screen.AllScreens)
    {
        var bounds = screen.Bounds;
        minx = Math.Min(minx, bounds.X);
        miny = Math.Min(miny, bounds.Y);
        maxx = Math.Max(maxx, bounds.Right);
        maxy = Math.Max(maxy, bounds.Bottom);
    }

    Form3 fs = new Form3();
    fs.Activate();
    Rectangle tempRect = new Rectangle(1, 0, maxx, maxy);
    this.DesktopBounds = tempRect;
}

I adopted the following approach for handling this issue. Created a new class which act as a wrapper for activity methods like this

public class ContextWrapper {
    public static String getString(Activity activity, int resourceId, String defaultValue) {
        if (activity != null) {
            return activity.getString(resourceId);
        } else {
            return defaultValue;
        }
    }

    //similar methods like getDrawable(), getResources() etc

}

Now wherever I need to access resources from fragments or activities, instead of directly calling the method, I use this class. In case the activity context is not null it returns the value of the asset and in case the context is null, it passes a default value (which is also specified by the caller of the function).

Important This is not a solution, this is an effective way where you can handle this crash gracefully. You would want to add some logs in cases where you are getting activity instance as null and try to fix that, if possible.

use Node sleep package. https://www.npmjs.com/package/sleep.

in your code you can use

var sleep = require('sleep'); 
sleep.sleep(n)

to sleep for a specific n seconds.

I just put an index.html file in /htdocs and type in http://127.0.0.1/index.html - and up comes the html.

Add a folder "named Forum" and type in 127.0.0.1/forum/???.???

The find command will take long time because it scans real files in file system.

The quickest way is using locate command, which will give result immediately:

locate "John"

If the command is not found, you need to install mlocate package and run updatedb command first to prepare the search database for the first time.

More detail here: https://medium.com/@thucnc/the-fastest-way-to-find-files-by-filename-mlocate-locate-commands-55bf40b297ab

Because at least one value is a string the + operator is being interpreted as a string concatenation operator. The simplest fix for this is to indicate that you intend for the values to be interpreted as numbers.

var total = +a + +b;

and

$('#total_price').val(+a + +b);

Or, better, just pull them out as numbers to begin with:

var a = +$('input[name=service_price]').val();
var b = +$('input[name=modem_price]').val();
var total = a+b;
$('#total_price').val(a+b);

See Mozilla's Unary + documentation.

Note that this is only a good idea if you know the value is going to be a number anyway. If this is user input you must be more careful and probably want to use parseInt and other validation as other answers suggest.

If you are using JDK 6 then you might want to check out ConcurrentHashMap

Note the putIfAbsent method in that class.

You can ABSOLUTELY do this without using anything MAVEN related. I personally use the NING HttpClient (v1.8.16, to support java6).

For whatever reason, Sonatype makes it incredibly difficulty to figure out what the correct URLs, headers, and payloads are supposed to be; and I had to sniff the traffic and guess... There are some barely useful blogs/documentation there, however it is either irrelevant to oss.sonatype.org, or it's XML based (and I found out it doesn't even work). Crap documentation on their part, IMHO, and hopefully future seekers can find this answer useful. Many thanks to https://stackoverflow.com/a/33414423/2101812 for their post, as it helped a lot.

If you release somewhere other than oss.sonatype.org, just replace it with whatever the correct host is.

Here is the (CC0 licensed) code I wrote to accomplish this. Where profile is your sonatype/nexus profileID (such as 4364f3bbaf163) and repo (such as comdorkbox-1003) are parsed from the response when you upload your initial POM/Jar.

    return sendHttpRequest(request);
}

How about:

find . -name '*.h' -o -name '*.cpp' -exec grep "CP_Image" {} \; -print

Another alternative to do the same thing is to filter on type=checkbox attribute:

$('input[type="checkbox"]').removeAttr('checked');

or

$('input[type="checkbox"]').prop('checked' , false);

Remeber that The difference between attributes and properties can be important in specific situations. Before jQuery 1.6, the .attr() method sometimes took property values into account when retrieving some attributes, which could cause inconsistent behavior. As of jQuery 1.6, the .prop() method provides a way to explicitly retrieve property values, while .attr() retrieves attributes.

Your class has a base class, and this base class also has a property (which is not virtual or abstract) called Events which is being overridden by your class. If you intend to override it put the "new" keyword after the public modifier. E.G.

public new EventsDataTable Events
{
  ..
}

If you don't wish to override it change your properties' name to something else.

For newest iTunes 12.7 and above can easily install IPA by copy and paste

1. Select and copy your .ipa (cmd+c or ctrl+c)
2. Connect phone to laptop
3. Open iTunes and select your device tab on top left of iTunes
4. Select the music tab
5. Paste the ipa (cmd+v or ctrl+v) not drag

Unfortunately this isn't entirely possible as the ClassLoader won't tell you what classes are available. You can, however, get fairly close doing something like this:

for (String classpathEntry : System.getProperty("java.class.path").split(System.getProperty("path.separator"))) {
    if (classpathEntry.endsWith(".jar")) {
        File jar = new File(classpathEntry);

        JarInputStream is = new JarInputStream(new FileInputStream(jar));

        JarEntry entry;
        while( (entry = is.getNextJarEntry()) != null) {
            if(entry.getName().endsWith(".class")) {
                // Class.forName(entry.getName()) and check
                //   for implementation of the interface
            }
        }
    }
}

Edit: johnstok is correct (in the comments) that this only works for standalone Java applications, and won't work under an application server.

There is no need for jQuery here, regular JavaScript will do:

var str = "Abc: Lorem ipsum sit amet";
str = str.substring(str.indexOf(":") + 1);

Or, the .split() and .pop() version:

var str = "Abc: Lorem ipsum sit amet";
str = str.split(":").pop();

Or, the regex version (several variants of this):

var str = "Abc: Lorem ipsum sit amet";
str = /:(.+)/.exec(str)[1];

Yes, there is one, it's the asterisk: *

a* // looks for 0 or more instances of "a"

This should be covered in any Java regex tutorial or documentation that you look up.

I know its too longtime to reply but just as an information purpose for future readers:

WebRequest

System.Object
    System.MarshalByRefObject
        System.Net.WebRequest

The WebRequest is an abstract base class. So you actually don't use it directly. You use it through it derived classes - HttpWebRequest and FileWebRequest.

You use Create method of WebRequest to create an instance of WebRequest. GetResponseStream returns data stream.

There are also FileWebRequest and FtpWebRequest classes that inherit from WebRequest. Normally, you would use WebRequest to, well, make a request and convert the return to either HttpWebRequest, FileWebRequest or FtpWebRequest, depend on your request. Below is an example:

Example:

var _request = (HttpWebRequest)WebRequest.Create("http://stackverflow.com");
var _response = (HttpWebResponse)_request.GetResponse();

WebClient

System.Object
        System.MarshalByRefObject
            System.ComponentModel.Component
                System.Net.WebClient

WebClient provides common operations to sending and receiving data from a resource identified by a URI. Simply, it’s a higher-level abstraction of HttpWebRequest. This ‘common operations’ is what differentiate WebClient from HttpWebRequest, as also shown in the sample below:

Example:

var _client = new WebClient();
var _stackContent = _client.DownloadString("http://stackverflow.com");

There are also DownloadData and DownloadFile operations under WebClient instance. These common operations also simplify code of what we would normally do with HttpWebRequest. Using HttpWebRequest, we have to get the response of our request, instantiate StreamReader to read the response and finally, convert the result to whatever type we expect. With WebClient, we just simply call DownloadData, DownloadFile or DownloadString.

However, keep in mind that WebClient.DownloadString doesn’t consider the encoding of the resource you requesting. So, you would probably end up receiving weird characters if you don’t specify and encoding.

NOTE: Basically "WebClient takes few lines of code as compared to Webrequest"

A few examples follow, going from basic through to adding transformations after the request and/or error handling:

Basic:

// Implementation code where T is the returned data shape
function api<T>(url: string): Promise<T> {
  return fetch(url)
    .then(response => {
      if (!response.ok) {
        throw new Error(response.statusText)
      }
      return response.json<T>()
    })

}

// Consumer
api<{ title: string; message: string }>('v1/posts/1')
  .then(({ title, message }) => {
    console.log(title, message)
  })
  .catch(error => {
    /* show error message */
  })

Data transformations:

Often you may need to do some tweaks to the data before its passed to the consumer, for example, unwrapping a top level data attribute. This is straight forward:

function api<T>(url: string): Promise<T> {
  return fetch(url)
    .then(response => {
      if (!response.ok) {
        throw new Error(response.statusText)
      }
      return response.json<{ data: T }>()
    })
    .then(data => { /* <-- data inferred as { data: T }*/
      return data.data
    })
}

// Consumer - consumer remains the same
api<{ title: string; message: string }>('v1/posts/1')
  .then(({ title, message }) => {
    console.log(title, message)
  })
  .catch(error => {
    /* show error message */
  })

Error handling:

I'd argue that you shouldn't be directly error catching directly within this service, instead, just allowing it to bubble, but if you need to, you can do the following:

function api<T>(url: string): Promise<T> {
  return fetch(url)
    .then(response => {
      if (!response.ok) {
        throw new Error(response.statusText)
      }
      return response.json<{ data: T }>()
    })
    .then(data => {
      return data.data
    })
    .catch((error: Error) => {
      externalErrorLogging.error(error) /* <-- made up logging service */
      throw error /* <-- rethrow the error so consumer can still catch it */
    })
}

// Consumer - consumer remains the same
api<{ title: string; message: string }>('v1/posts/1')
  .then(({ title, message }) => {
    console.log(title, message)
  })
  .catch(error => {
    /* show error message */
  })

Edit

There has been some changes since writing this answer a while ago. As mentioned in the comments, response.json<T> is no longer valid. Not sure, couldn't find where it was removed.

For later releases, you can do:

// Standard variation
function api<T>(url: string): Promise<T> {
  return fetch(url)
    .then(response => {
      if (!response.ok) {
        throw new Error(response.statusText)
      }
      return response.json() as Promise<T>
    })
}


// For the "unwrapping" variation

function api<T>(url: string): Promise<T> {
  return fetch(url)
    .then(response => {
      if (!response.ok) {
        throw new Error(response.statusText)
      }
      return response.json() as Promise<{ data: T }>
    })
    .then(data => {
        return data.data
    })
}

You can parse the text as a string, which creates an Element, and create an ElementTree using that Element.

import xml.etree.ElementTree as ET
tree = ET.ElementTree(ET.fromstring(xmlstring))

I just came across this issue and the documentation, while complete, is not very straightforward on the difference in usage between the parse() and fromstring() methods.

In addition to the Oracle instant client, you may also need to install the Oracle ODAC components and put the path to them into your system path. cx_Oracle seems to need access to the oci.dll file that is installed with them.

Also check that you get the correct version (32bit or 64bit) of them that matches your: python, cx_Oracle, and instant client versions.

It looks like JSON - it might be overkill, depending on the situation, but you could consider using a JSON library (e.g. http://json.org/java/) to parse it:

    String arr = "[1,2]";

    JSONArray jsonArray = (JSONArray) new JSONObject(new JSONTokener("{data:"+arr+"}")).get("data");

    int[] outArr = new int[jsonArray.length()]; 

    for(int i=0; i<jsonArray.length(); i++) {
        outArr[i] = jsonArray.getInt(i);
    }

Better you update your eclipse by clicking it on help >> check for updates, also you can start eclipse by entering command in command prompt eclipse -clean.
Hope this will help you.

As Kintaro already says, person is a method (because of def) and always returns a new Person instance. As you found out it would work if you change the method to a var or val:

val person = new Person("Kumar",12)

Another possibility would be:

def person = new Person("Kumar",12)
val p = person
p.age=20
println(p.age)

However, person.age=20 in your code is allowed, as you get back a Person instance from the person method, and on this instance you are allowed to change the value of a var. The problem is, that after that line you have no more reference to that instance (as every call to person will produce a new instance).

This is nothing special, you would have exactly the same behavior in Java:

class Person{ 
   public int age; 
   private String name;
   public Person(String name; int age) {
      this.name = name;  
      this.age = age;
   }
   public String name(){ return name; }
}

public Person person() { 
  return new Person("Kumar", 12); 
}

person().age = 20;
System.out.println(person().age); //--> 12

I would do this in CSS:

div.centered {
  position: fixed; 
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
}

then in HTML:

<div class="centered"></div>

I access the ticketNumber parameter for my multipart post request in the following way.

$data = $request->request->all();
$ticketNumber = $data["ticketNumber"];

I noticed something else about your coding.... look

INSERT INTO reports_services (id,title,description,cost) VALUES (0, 'test title', 'test decription ', '3.80')

in your "CREATE TABLE" code you have the id set to "AUTO_INCREMENT" which means it's automatically generating a result for that field.... but in your above code you include it as one of the insertions and in the "VALUES" you have a 0 there... idk if that's your way of telling us you left it blank because it's set to AUTO_INC. or if that's the actual code you have... if it's the code you have not only should you not be trying to send data to a field set to generate it automatically, but the RIGHT WAY to do it WRONG would be

'0',

you put

0,

lol....so that might be causing some of the problem... I also just noticed in the code after "test description" you have a space before the '.... that might be throwing something off too.... idk.. I hope this helps n maybe resolves some other problem you might be pulling your hair out about now.... speaking of which.... I need to figure out my problem before I tear all my hair out..... good luck.. :)

UPDATE.....

I almost forgot... if you have the 0 there to show that it's blank... you could be entering "test title" as the id and "test description" as the title then "3.whatever cents" for the description leaving "cost" empty...... which could be why it maxed out because if I'm not mistaking you have it set to NOT NULL.... and you left it null... so it forced something... maybe.... lol

Also you can try to use

display:inline-block;

if you would like the span element to align horizontally.

Incase you would like to align span elements vertically, just use

 display:block;

Pay attention that accept() is not thread safe, so the call is wrapped within synchronized.

64: synchronized(servSock) {
65:     clientSocket = servSock.accept();
66: }

In fact, most compilers emit the same code for both functions calls, because references are generally implemented using pointers.

Following this logic, when an argument of (non-const) reference type is used in the function body, the generated code will just silently operate on the address of the argument and it will dereference it. In addition, when a call to such a function is encountered, the compiler will generate code that passes the address of the arguments instead of copying their value.

Basically, references and pointers are not very different from an implementation point of view, the main (and very important) difference is in the philosophy: a reference is the object itself, just with a different name.

References have a couple more advantages compared to pointers (e. g. they can't be NULL, so they are safer to use). Consequently, if you can use C++, then passing by reference is generally considered more elegant and it should be preferred. However, in C, there's no passing by reference, so if you want to write C code (or, horribile dictu, code that compiles with both a C and a C++ compiler, albeit that's not a good idea), you'll have to restrict yourself to using pointers.

There isn't anything like that in standard Linq, but there is a ForEach operator in MoreLinq.

I have written a procedure that can calculate the same, but you have to enter the latitude and longitude in the respective table.

I don't think any of the answers really make it clear exactly what side effects it has, or indeed, what it is.

constexpr and const at namespace/file-scope are identical when initialised with a literal or expression; but with a function, const can be initialised by any function, but constexpr initialised by a non-constexpr (a function that isn't marked with constexpr or a non constexpr expression) will generate a compiler error. Both constexpr and const are implicitly internal linkage for variables (well actually, they don't survive to get to the linking stage if compiling -O1 and stronger, and static doesn't force the compiler to emit an internal (local) linker symbol for const or constexpr when at -O1 or stronger; the only time it does this is if you take the address of the variable. const and constexpr will be an internal symbol unless expressed with extern i.e. extern constexpr/const int i = 3; needs to be used). On a function, constexpr makes the function permanently never reach the linking stage (regardless of extern or inline in the definition or -O0 or -Ofast), whereas const never does, and static and inline only have this effect on -O1 and above. When a const/constexpr variable is initialised by a constexpr function, the load is always optimised out with any optimisation flag, but it is never optimised out if the function is only static or inline, or if the variable is not a const/constexpr.

Standard compilation (-O0)

#include<iostream>
constexpr int multiply (int x, int y)
{

  return x * y;
}

extern const int val = multiply(10,10);
int main () {
  std::cout << val;
} 

compiles to

val:
        .long   100  //extra external definition supplied due to extern

main:
        push    rbp
        mov     rbp, rsp
        mov     esi, 100 //substituted in as an immediate
        mov     edi, OFFSET FLAT:_ZSt4cout
        call    std::basic_ostream<char, std::char_traits<char> >::operator<<(int)
        mov     eax, 0
        pop     rbp
        ret

__static_initialization_and_destruction_0(int, int):
        . 
        . 
        . 

However

#include<iostream>
const int multiply (int x, int y)
{

  return x * y;
}

const int val = multiply(10,10); //constexpr is an error
int main () {
  std::cout << val;
}

Compiles to

multiply(int, int):
        push    rbp
        mov     rbp, rsp
        mov     DWORD PTR [rbp-4], edi
        mov     DWORD PTR [rbp-8], esi
        mov     eax, DWORD PTR [rbp-4]
        imul    eax, DWORD PTR [rbp-8]
        pop     rbp
        ret

main:
        push    rbp
        mov     rbp, rsp
        mov     eax, DWORD PTR val[rip]
        mov     esi, eax
        mov     edi, OFFSET FLAT:_ZSt4cout
        call    std::basic_ostream<char, std::char_traits<char> >::operator<<(int)
        mov     eax, 0
        pop     rbp
        ret

__static_initialization_and_destruction_0(int, int):
        . 
        . 
        . 
        mov     esi, 10
        mov     edi, 10
        call    multiply(int, int)
        mov     DWORD PTR val[rip], eax

This clearly shows that constexpr causes the initialisation of the const/constexpr file-scope variable to occur at compile time and produce no global symbol, whereas not using it causes initialisation to occur before main at runtime.

Compiling using -Ofast

Even -Ofast doesn't optimise out the load! https://godbolt.org/z/r-mhif, so you need constexpr

constexpr functions can also be called from inside other constexpr functions for the same result. constexpr on a function also prevents use of anything that can't be done at compile time in the function; for instance, a call to the << operator on std::cout.

constexpr at block scope behaves the same in that it produces an error if initialised by a non-constexpr function; the value is also substituted in immediately.

In the end, its main purpose is like C's inline function, but it is only effective when the function is used to initialise file-scope variables (which functions cannot do on C, but they can on C++ because it allows dynamic initialisation of file-scope variables), except the function cannot export a global/local symbol to the linker as well, even using extern/static, which you could with inline on C; block-scope variable assignment functions can be inlined simply using an -O1 optimisation without constexpr on C and C++.

I use pip freeze to get the packages I need into a requirements.txt file and add that to my repository. I tried to think of a way of why you would want to store the entire virtualenv, but I could not.

Assuming task is to find last element that satisfies some condition in a list (i.e. first when looking backwards), I'm getting following numbers:

>>> min(timeit.repeat('for i in xrange(len(xs)-1,-1,-1):\n    if 128 == xs[i]: break', setup='xs, n = range(256), 0', repeat=8))
4.6937971115112305
>>> min(timeit.repeat('for i in reversed(xrange(0, len(xs))):\n    if 128 == xs[i]: break', setup='xs, n = range(256), 0', repeat=8))
4.809093952178955
>>> min(timeit.repeat('for i, x in enumerate(reversed(xs), 1):\n    if 128 == x: break', setup='xs, n = range(256), 0', repeat=8))
4.931743860244751
>>> min(timeit.repeat('for i, x in enumerate(xs[::-1]):\n    if 128 == x: break', setup='xs, n = range(256), 0', repeat=8))
5.548468112945557
>>> min(timeit.repeat('for i in xrange(len(xs), 0, -1):\n    if 128 == xs[i - 1]: break', setup='xs, n = range(256), 0', repeat=8))
6.286104917526245
>>> min(timeit.repeat('i = len(xs)\nwhile 0 < i:\n    i -= 1\n    if 128 == xs[i]: break', setup='xs, n = range(256), 0', repeat=8))
8.384078979492188

So, the ugliest option xrange(len(xs)-1,-1,-1) is the fastest.

Your code would be like this:

int *p = (int *)0x28ff44;

int needs to be the type of the object that you are referencing or it can be void.

But be careful so that you don't try to access something that doesn't belong to your program.

It's a reserved keyword (like return, filter, function, break).

Also, as per Section 7.6.4 of Bruce Payette's Powershell in Action:

But what happens when you want a script to exit from within a function defined in that script? ... To make this easier, Powershell has the exit keyword.

Of course, as other have pointed out, it's not hard to do what you want by wrapping exit in a function:
