Your command is completely incorrect. The output format is not rawvideo and you don't need the bitstream filter h264_mp4toannexb which is used when you want to convert the h264 contained in an mp4 to the Annex B format used by MPEG-TS for example. What you want to use instead is the aac_adtstoasc for the AAC streams.

ffmpeg -i http://.../playlist.m3u8 -c copy -bsf:a aac_adtstoasc output.mp4

Well, to start with List<T> does have the FindAll and ConvertAll methods - but the more idiomatic, modern approach is to use LINQ:

// Find all the people older than 30
var query1 = list.Where(person => person.Age > 30);

// Find each person's name
var query2 = list.Select(person => person.Name);

You'll need a using directive in your file to make this work:

using System.Linq;

Note that these don't use strings to express predicates and projects - they use delegates, usually created from lambda expressions as above.

If lambda expressions and LINQ are new to you, I would suggest you get a book covering LINQ first, such as LINQ in Action, Pro LINQ, C# 4 in a Nutshell or my own C# in Depth. You certainly can learn LINQ just from web tutorials, but I think it's such an important technology, it's worth taking the time to learn it thoroughly.

I've made a small snippet you can use:

from django.conf import settings
from django.db import connection


def sql_echo(method, *args, **kwargs):
    settings.DEBUG = True
    result = method(*args, **kwargs)
    for query in connection.queries:
        print(query)
    return result


# HOW TO USE EXAMPLE:
# 
# result = sql_echo(my_method, 'whatever', show=True)

It takes as parameters function (contains sql queryies) to inspect and args, kwargs needed to call that function. As the result it returns what function returns and prints SQL queries in a console.

A viable option, and one that I have personally used, would be to add your own header to the first line of the file. I did this for a custom model format for my game. Basically, I have a tool that optimizes my .obj files, getting rid of the crap I don't need, converts them to a better layout, and then writes the total number of lines, faces, normals, vertices, and texture UVs on the very first line. That data is then used by various array buffers when the model is loaded.

This is also useful because you only need to loop through the file once to load it in, instead of once to count the lines, and again to read the data into your created buffers.

Heres a truly "Reversible Dictionary", Based upon Adam Acosta's solution, but enforcing val-to-key calls to be unique and easily return key from value:

from collections import UserDict


class ReversibleDict(UserDict):
    def __init__(self, enforce_unique=True, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.val_to_keys = {}
        self.check_val = self.check_unique if enforce_unique else lambda x: x

    def __setitem__(self, key, value):
        self.check_val(value)
        super().__setitem__(key, value)
        self.val_to_keys[value] = key

    def __call__(self, value):
        return self.val_to_keys[value]

    def check_unique(self, value):
        assert value not in self.val_to_keys, f"Non unique value '{value}'"
        return value

If you want to enforce uniqueness on dictionary values ensure to set enforce_unique=True. to get keys from values just do rev_dict(value), to call values from keys just do as usual dict['key'], here's an example of usage:

rev_dict = ReversibleDict(enforce_unique=True)
rev_dict["a"] = 1
rev_dict["b"] = 2
rev_dict["c"] = 3
print("full dictinoary is: ", rev_dict)
print("value for key 'b' is: ", rev_dict["b"])
print("key for value '2' is: ", rev_dict(2))
print("tring to set another key with the same value results in error: ")
rev_dict["d"] = 1

I've been battling with this for days, and have finally figured out how to get the "pip install psycopg2" command to run in a virtualenv in Windows (running Cygwin).

I was hitting the "pg_config executable not found." error, but I had already downloaded and installed postgres in Windows. It installed in Cygwin as well; running "which pg_config" in Cygwin gave "/usr/bin/pg_config", and running "pg_config" gave sane output -- however the version installed with Cygwin is:

VERSION = PostgreSQL 8.2.11

This won't work with the current version of psycopg2, which appears to require at least 9.1. When I added "c:\Program Files\PostgreSQL\9.2\bin" to my Windows path, the Cygwin pip installer was able to find the correct version of PostgreSQL, and I was able to successfully install the module using pip. (This is probably preferable to using the Cygwin version of PostgreSQL anyway, as the native version will run much quicker).

If you aren't worried about generating the extra elements using the split then filter could handle the issue you mention of the trailing slash (Assuming you have browser support for filter).

url.split('/').filter(function (s) { return !!s }).pop()

If you have many class level properties then a singleton pattern might be in order. Something like this:

// Foo.h
@interface Foo

+ (Foo *)singleton;

@property 1 ...
@property 2 ...
@property 3 ...

@end

And

// Foo.m

#import "Foo.h"

@implementation Foo

static Foo *_singleton = nil;

+ (Foo *)singleton {
    if (_singleton == nil) _singleton = [[Foo alloc] init];

    return _singleton;
}

@synthesize property1;
@synthesize property2;
@synthesise property3;

@end

Now access your class-level properties like this:

[Foo singleton].property1 = value;
value = [Foo singleton].property2;

Just use it...

Firstly include the unistd.h header file, #include<unistd.h>, and use this function for pausing your program execution for desired number of seconds:

sleep(x);

x can take any value in seconds.

If you want to pause the program for 5 seconds it is like this:

sleep(5);

It is correct and I use it frequently.

It is valid for C and C++.

Take a look at the JavaDoc for RestTemplate.

There is the corresponding getForObject methods that are the HTTP GET equivalents of postForObject, but they doesn't appear to fulfil your requirements of "GET with headers", as there is no way to specify headers on any of the calls.

Looking at the JavaDoc, no method that is HTTP GET specific allows you to also provide header information. There are alternatives though, one of which you have found and are using. The exchange methods allow you to provide an HttpEntity object representing the details of the request (including headers). The execute methods allow you to specify a RequestCallback from which you can add the headers upon its invocation.

You can also check out dateparser

dateparser provides modules to easily parse localized dates in almost any string formats commonly found on web pages.

Install:

$ pip install dateparser

This is, I think, the easiest way you can parse dates.

The most straightforward way is to use the dateparser.parse function, that wraps around most of the functionality in the module.

Sample Code:

import dateparser

t1 = 'Jun 1 2005  1:33PM'
t2 = 'Aug 28 1999 12:00AM'

dt1 = dateparser.parse(t1)
dt2 = dateparser.parse(t2)

print(dt1)
print(dt2)

Output:

2005-06-01 13:33:00
1999-08-28 00:00:00

I think you should change that like so:

<input value={this.state.value} onChange={(e) => {this.handleChange(e)}}/>

That is in principle the same as onClick={this.handleClick.bind(this)} as you did on the button.

So if you want to call handleChange() when the button is clicked, than:

<button onClick={this.handleChange.bind(this)}>Change Input</button>

or

handleClick () {
  this.setState({value: 'another random text'});
  this.handleChange();
}

Update: I still get upvotes on this question, which is still the accepted answer and which I think I answered poorly. In the spirit of making sure the best info is out there, I have decided to update this answer.

In modern Android I would use ConstraintLayout to do this. It is more performant and straightforward.

<ConstraintLayout>
   <View
      android:id="@+id/view1"
      ...other attributes elided... />
   <View
      android:id="@id/view2"        
      app:layout_constraintTop_toBottomOf="@id/view1" />
      ...other attributes elided... />

   ...etc for other views that should be aligned top to bottom...

   <TextView
    app:layout_constraintBottom_toBottomOf="parent" />

If you don't want to use a ConstraintLayout, using a LinearLayout with an expanding view is a straightforward and great way to handle taking up the extra space (see the answer by @Matthew Wills). If you don't want to expand the background of any of the Views above the bottom view, you can add an invisible View to take up the space.

The answer I originally gave works but is inefficient. Inefficiency may not be a big deal for a single top level layout, but it would be a terrible implementation in a ListView or RecyclerView, and there just isn't any reason to do it since there are better ways to do it that are roughly the same level of effort and complexity if not simpler.

Take the TextView out of the LinearLayout, then put the LinearLayout and the TextView inside a RelativeLayout. Add the attribute android:layout_alignParentBottom="true" to the TextView. With all the namespace and other attributes except for the above attribute elided:

<RelativeLayout>
  <LinearLayout>
    <!-- All your other elements in here -->
  </LinearLayout>
  <TextView
    android:layout_alignParentBottom="true" />
</RelativeLayout>

Since PostgreSQL 9.1 there is the convenient FOREACH:

DO
$do$
DECLARE
   m   varchar[];
   arr varchar[] := array[['key1','val1'],['key2','val2']];
BEGIN
   FOREACH m SLICE 1 IN ARRAY arr
   LOOP
      RAISE NOTICE 'another_func(%,%)',m[1], m[2];
   END LOOP;
END
$do$

Solution for older versions:

DO
$do$
DECLARE
   arr varchar[] := '{{key1,val1},{key2,val2}}';
BEGIN
   FOR i IN array_lower(arr, 1) .. array_upper(arr, 1)
   LOOP
      RAISE NOTICE 'another_func(%,%)',arr[i][1], arr[i][2];
   END LOOP;
END
$do$

Also, there is no difference between varchar[] and varchar[][] for the PostgreSQL type system. I explain in more detail here.

The DO statement requires at least PostgreSQL 9.0, and LANGUAGE plpgsql is the default (so you can omit the declaration).

Since the desired page will be called from a different domain you need to return jsonp instead of a json.

$.get("http://theSource", {callback : "?" }, "jsonp",  function(data) {
    $('#summary').text(data.result);
});

Otherwise IE8 is not acting right. Also you should use:

<meta http-equiv="X-UA-Compatible" content="IE=EDGE" />

In case you want to see what this all means, here is a blow-by-blow of everything:

CREATE TABLE `users_partners` (
  `uid` int(11) NOT NULL DEFAULT '0',
  `pid` int(11) NOT NULL DEFAULT '0',
  PRIMARY KEY (`uid`,`pid`),
  KEY `partner_user` (`pid`,`uid`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8

Primary key is based on both columns of this quick reference table. A Primary key requires unique values.

Let's begin:

INSERT INTO users_partners (uid,pid) VALUES (1,1);
...1 row(s) affected

INSERT INTO users_partners (uid,pid) VALUES (1,1);
...Error Code : 1062
...Duplicate entry '1-1' for key 'PRIMARY'

INSERT IGNORE INTO users_partners (uid,pid) VALUES (1,1);
...0 row(s) affected

INSERT INTO users_partners (uid,pid) VALUES (1,1) ON DUPLICATE KEY UPDATE uid=uid
...0 row(s) affected

note, the above saved too much extra work by setting the column equal to itself, no update actually needed

REPLACE INTO users_partners (uid,pid) VALUES (1,1)
...2 row(s) affected

and now some multiple row tests:

INSERT INTO users_partners (uid,pid) VALUES (1,1),(1,2),(1,3),(1,4)
...Error Code : 1062
...Duplicate entry '1-1' for key 'PRIMARY'

INSERT IGNORE INTO users_partners (uid,pid) VALUES (1,1),(1,2),(1,3),(1,4)
...3 row(s) affected

no other messages were generated in console, and it now has those 4 values in the table data. I deleted everything except (1,1) so I could test from the same playing field

INSERT INTO users_partners (uid,pid) VALUES (1,1),(1,2),(1,3),(1,4) ON DUPLICATE KEY UPDATE uid=uid
...3 row(s) affected

REPLACE INTO users_partners (uid,pid) VALUES (1,1),(1,2),(1,3),(1,4)
...5 row(s) affected

So there you have it. Since this was all performed on a fresh table with nearly no data and not in production, the times for execution were microscopic and irrelevant. Anyone with real-world data would be more than welcome to contribute it.

You shouldn't have to unserialize anything in PHP from the jquery serialize method. If you serialize the data, it should be sent to PHP as query parameters if you are using a GET method ajax request or post vars if you are using a POST ajax request. So in PHP, you would access values like $_POST["varname"] or $_GET["varname"] depending on the request type.

The serialize method just takes the form elements and puts them in string form. "varname=val&var2=val2"

Just use this npm package, it will give the web-output as well as terminal output in nice formatted table view.

As an alternative approach to trying to parse the string and catching NumberFormatException, you could use a regex; e.g.

if (Pattern.compile("-?[0-9]+").matches(str)) {
    // its an integer
}

This is likely to be faster, especially if you precompile and reuse the regex.

However, the problem with this approach is that Integer.parseInt(str) will also fail if str represents a number that is outside range of legal int values. While it is possible to craft a regex that only matches integers in the range Integer.MIN_INT to Integer.MAX_INT, it is not a pretty sight. (And I am not going to try it ...)

On the other hand ... it may be acceptable to treat "not an integer" and "integer too large" separately for validation purposes.

I just want to provide some other people with help with a more serious variant of this problem. In some situations, the error ("Row size too large .. Changing some columns to TEXT or BLOB") will occur even with "alter table drop column" and "alter table modify column" statements!

Consequently you can become completely stuck, not able to change a varchar to a text, or drop columns (trying to solve the problem ironically results in the same message).

If you have this problem, the solution is to alter or drop multiple columns at once. You can do this in MySQL with the syntax "alter table example drop column a, drop column b, drop column c" and if you drop enough columns at once, it will actually execute rather than raising the error.

If the server's certificate is self-signed, then this is working as designed and you will have to import the server's certificate into your keystore.

Assuming the server certificate is signed by a well-known CA, this is happening because the set of CA certificates available to a modern browser is much larger than the limited set that is shipped with the JDK/JRE.

The EasySSL solution given in one of the posts you mention just buries the error, and you won't know if the server has a valid certificate.

You must import the proper Root CA into your keystore to validate the certificate. There's a reason you can't get around this with the stock SSL code, and that's to prevent you from writing programs that behave as if they are secure but are not.

There is the command line parameter --spider exactly for this. In this mode, wget does not download the files and its return value is zero if the resource was found and non-zero if it was not found. Try this (in your favorite shell):

wget -q --spider address
echo $?

Or if you want full output, leave the -q off, so just wget --spider address. -nv shows some output, but not as much as the default.

Selecting a HTTP response code is quite an easy task and can be described by simple rules. The only tricky part which is often forgotten is paragraph 6.5 from RFC 7231:

Except when responding to a HEAD request, the server SHOULD send a representation containing an explanation of the error situation, and whether it is a temporary or permanent condition.

Rules are as following:

1. If request was successful, then return 2xx code (3xx for redirect). If there was an internal logic error on a server, then return 5xx. If there is anything wrong in client request, then return 4xx code.
2. Look through available response code from selected category. If one of them has a name which matches well to your situation, you can use it. Otherwise just fallback to x00 code (200, 400, 500). If you doubt, fallback to x00 code.
3. Return error description in response body. For 4xx codes it must contain enough information for client developer to understand the reason and fix the client. For 5xx because of security reasons no details must be revealed.
4. If client needs to distinguish different errors and have different reaction depending on it, define a machine readable and extendible error format and use it everywhere in your API. It is good practice to make that from very beginning.
5. Keep in mind that client developer may do strange things and try to parse strings which you return as human readable description. And by changing the strings you will break such badly written clients. So always provide machine readable description and try to avoid reporting additional information in text.

So in your case I'd returned 400 error and something like this if "Roman" is obtained from user input and client must have specific reaction:

{
    "error_type" : "unsupported_resource",
    "error_description" : "\"Roman\" is not supported"
}

or a more generic error, if such situation is a bad logic error in a client and is not expected, unless developer made something wrong:

{
    "error_type" : "malformed_json",
    "error_description" : "\"Roman\" is not supported for \"requestedResource\" field"
}

look at

http://jtds.sourceforge.net/faq.html#driverImplementation

What is the URL format used by jTDS?

The URL format for jTDS is:

jdbc:jtds:<server_type>://<server>[:<port>][/<database>][;<property>=<value>[;...]]

... domain Specifies the Windows domain to authenticate in. If present and the user name and password are provided, jTDS uses Windows (NTLM) authentication instead of the usual SQL Server authentication (i.e. the user and password provided are the domain user and password). This allows non-Windows clients to log in to servers which are only configured to accept Windows authentication.

If the domain parameter is present but no user name and password are provided, jTDS uses its native Single-Sign-On library and logs in with the logged Windows user's credentials (for this to work one would obviously need to be on Windows, logged into a domain, and also have the SSO library installed -- consult README.SSO in the distribution on how to do this).

To read a file line by line (also for extreme big files) can be done by the following functions:

DDFileReader * reader = [[DDFileReader alloc] initWithFilePath:pathToMyFile];
NSString * line = nil;
while ((line = [reader readLine])) {
  NSLog(@"read line: %@", line);
}
[reader release];

Or:

DDFileReader * reader = [[DDFileReader alloc] initWithFilePath:pathToMyFile];
[reader enumerateLinesUsingBlock:^(NSString * line, BOOL * stop) {
  NSLog(@"read line: %@", line);
}];
[reader release];

Integers:

int value = 100000; 
String.format("%,d", value); // outputs 100,000

Doubles:

double value = 21403.3144d;
String.format("%,.2f", value); // outputs 21,403.31

String.format is pretty powerful.

- Edited per psuzzi feedback.

You can use the following code.

main()
{
    int i = 0,j=0,count[26]={0};
    char ch = 97;
    char string[100]="Hello how are you buddy ?";
    for (i = 0; i < 100; i++)
    {
        for(j=0;j<26;j++)
            {
            if (tolower(string[i]) == (ch+j))
                {
                    count[j]++;
                }
        }
    }
    for(j=0;j<26;j++)
        {

            printf("\n%c -> %d",97+j,count[j]);

    }

}

Hope this helps.

You can check the version of your genymotion and virtualbox. The genymotion 2.5.3 would work better with virtualbox 4.3.30.

Edit:

If you have snap or want to install it, just do:

$ sudo snap install postman

if you don't have it, install it as:

$ sudo apt update
$ sudo apt install snapd

Another way is create an script:

First create this script:

create a file install-postman.sh, inside of it add:

#!/bin/bash
cd /tmp || exit
echo "Downloading Postman ..."
wget -q https://dl.pstmn.io/download/latest/linux?arch=64 -O postman.tar.gz
tar -xzf postman.tar.gz
rm postman.tar.gz

echo "Installing to opt..."
if [ -d "/opt/Postman" ];then
    sudo rm -rf /opt/Postman
fi
sudo mv Postman /opt/Postman

echo "Creating symbolic link..."
if [ -L "/usr/bin/postman" ];then
    sudo rm -f /usr/bin/postman
fi
sudo ln -s /opt/Postman/Postman /usr/bin/postman

echo "Installation completed successfully."
echo "You can use Postman!"

run it in terminal with:

$ sh install-postman.sh

Then create the desktop launcher:

Postman.desktop

[Desktop Entry]
Encoding=UTF-8
Name=Postman
Exec=postman
Icon=/opt/Postman/resources/app/assets/icon.png
Terminal=false
Type=Application
Categories=Development;

Put this file in your desktop if you want (don't forget give to it execution permissions). Double click, and that's it!

To date (mysql 8.0.18) there is no suitable function inside mysql to re-create indexes.
Since mysql 8.0 myisam is slowly phasing into deprecated status, innodb is the current main storage engine.
In most practical cases innodb is the best choice and it's supposed to keep indexes working well.
In most practical cases innodb also does a good job, you do not need to recreate indexes. Almost always.

When it comes to large tables with hundreds of GB data amd rows and a lot of writing the situation changes, indexes can degrade in performance.
In my personal case I've seen performance drop from ~15 minutes for a count(*) using a secondary index to 4300 minutes after 2 months of writing to the table with linear time increase.
After recreating the index the performance goes back to 15 minutes.

To date we have two options to do that:
1) OPTIMIZE TABLE (or ALTER TABLE)
Innodb doesn't support optimization so in both cases the entire table will be read and re-created.
This means you need the storage for the temporary file and depending on the table a lot of time (I've cases where an optimize takes a week to complete). This will compact the data and rebuild all indexes.
Despite not being officially recommended, I highly recommend the OPTIMIZE process on write-heavy tables up to 100GB in size.

2) ALTER TABLE DROP KEY -> ALTER TABLE ADD KEY
You manually drop the key by name, you manually create it again. In a production environment you'll want to create it first, then drop the old version.
The upside: this can be a lot faster than optimize. The downside: you need to manually create the syntax.
"SHOW CREATE TABLE" can be used to quickly see which indexes are available and how they are called.

Appendix:
1) To just update statistics you can use the already mentioned "ANALYZE TABLE".
2) If you experience performance degradation on write-heavy servers you might need to restart mysql. There are a couple of bugs in current mysql (8.0) that can cause significant slowdown without showing up in error log. Eventually those slowdowns lead to a server crash but it can take weeks or even months to build up to the crash, in this process the server gets slower and slower in responses.
3) If you wish to re-create a large table that takes weeks to complete or fails after hours due to internal data integrity problems you should do a CREATE TABLE LIKE, INSERT INTO SELECT *. then 'atomic RENAME' the tables.
4) If INSERT INTO SELECT * takes hours to days to complete on huge tables you can speed up the process by about 20-30 times using a multi-threaded approach. You "partition" the table into chunks and INSERT INTO SELECT * in parallel.

This a great tool for debugging & logging php: PHp Debugger & Logger

It works right out of the box with just 3 lines of code. It can send messages to the js console for ajax debugging and can replace the error handler. It also dumps information about variables like var_dump() and print_r(), but in a more readable format. Very nice tool!

Here are the significant differences between lateinit var and by lazy { ... } delegated property:

• lazy { ... } delegate can only be used for val properties, whereas lateinit can only be applied to vars, because it can't be compiled to a final field, thus no immutability can be guaranteed;

• lateinit var has a backing field which stores the value, and by lazy { ... } creates a delegate object in which the value is stored once calculated, stores the reference to the delegate instance in the class object and generates the getter for the property that works with the delegate instance. So if you need the backing field present in the class, use lateinit;

• In addition to vals, lateinit cannot be used for nullable properties or Java primitive types (this is because of null used for uninitialized value);

• lateinit var can be initialized from anywhere the object is seen from, e.g. from inside a framework code, and multiple initialization scenarios are possible for different objects of a single class. by lazy { ... }, in turn, defines the only initializer for the property, which can be altered only by overriding the property in a subclass. If you want your property to be initialized from outside in a way probably unknown beforehand, use lateinit.

• Initialization by lazy { ... } is thread-safe by default and guarantees that the initializer is invoked at most once (but this can be altered by using another lazy overload). In the case of lateinit var, it's up to the user's code to initialize the property correctly in multi-threaded environments.

• A Lazy instance can be saved, passed around and even used for multiple properties. On contrary, lateinit vars do not store any additional runtime state (only null in the field for uninitialized value).

• If you hold a reference to an instance of Lazy, isInitialized() allows you to check whether it has already been initialized (and you can obtain such instance with reflection from a delegated property). To check whether a lateinit property has been initialized, you can use property::isInitialized since Kotlin 1.2.

• A lambda passed to by lazy { ... } may capture references from the context where it is used into its closure.. It will then store the references and release them only once the property has been initialized. This may lead to object hierarchies, such as Android activities, not being released for too long (or ever, if the property remains accessible and is never accessed), so you should be careful about what you use inside the initializer lambda.

Also, there's another way not mentioned in the question: Delegates.notNull(), which is suitable for deferred initialization of non-null properties, including those of Java primitive types.

Checkout intent properties like no history , clear back stack etc ... Intent.setFlags

Intent mStartActivity = new Intent(HomeActivity.this, SplashScreen.class);
int mPendingIntentId = 123456;
PendingIntent mPendingIntent = PendingIntent.getActivity(HomeActivity.this, mPendingIntentId, mStartActivity,
PendingIntent.FLAG_CANCEL_CURRENT);
AlarmManager mgr = (AlarmManager) HomeActivity.this.getSystemService(Context.ALARM_SERVICE);
mgr.set(AlarmManager.RTC, System.currentTimeMillis() + 100, mPendingIntent);
System.exit(0);

$str = "
Dear friends, I just wanted so Hello. How are you guys? I'm fine, thanks!<br />

echo str_replace(array("\n", "\r"), '', $str);  // echo $str in a single line

It is same as above answers, but is simple in steps

c:\SRC\folder1

c:\SRC\folder2

c:\SRC\folder3

c:\SRC\folder4

to copy all above folders to c:\DST\ except folder1 and folder2.

Step1: create a file c:\list.txt with below content, one folder name per one line

folder1\

folder2\

Step2: Go to command pompt and run as below xcopy c:\SRC*.* c:\DST*.* /EXCLUDE:c:\list.txt

You can change the size of the plot by adding this before you create the figure.

plt.rcParams["figure.figsize"] = [16,9]

For older .xls files, you can use xlrd

either you can use xlrd directly by importing it. Like below

import xlrd
wb = xlrd.open_workbook(file_name)

Or you can also use pandas pd.read_excel() method, but do not forget to specify the engine, though the default is xlrd, it has to be specified.

pd.read_excel(file_name, engine = xlrd)

Both of them work for older .xls file formats. Infact I came across this when I used OpenPyXL, i got the below error

InvalidFileException: openpyxl does not support the old .xls file format, please use xlrd to read this file, or convert it to the more recent .xlsx file format.

I recommend looking at modern databases like NoSQL and also I agree with user1252434's post. For instance I am storing a few < 500kb PNGs as base64 on my Mongo db with binary set to true with no performance hit at all. Mongo can be used to store large files like 10MB videos and that can offer huge time saving advantages in metadata searches for those videos, see storing large objects and files in mongodb.

With this, you can perform some code in the get or set scope.

private string _myProperty;
public string myProperty
{
    get { return _myProperty; }
    set { _myProperty = value; }
}

You also can use automatic properties:

public string myProperty
{
    get;
    set;
}

And .Net Framework will manage for you. It was create because it is a good pratice and make it easy to do.

You also can control the visibility of these scopes, for sample:

public string myProperty
{
    get;
    private set;
}

public string myProperty2
{
    get;
    protected set;
}

public string myProperty3
{
    get; 
}

Update

Now in C# you can initialize the value of a property. For sample:

public int Property { get; set; } = 1;

If also can define it and make it readonly, without a set.

public int Property { get; } = 1;

And finally, you can define an arrow function.

public int Property => GetValue();

You can use ToList to convert to a list. For example,

SomeItems.ToList()[1]

Just follow these Steps :

If you want the contents of, say, C1 to mirror the contents of cell A1, you just need to set the formula in C1 to =A1. From this point forward, anything you type in A1 will show up in C1 as well.

To Link Multiple Cells in Excel From Another Worksheet :

Step 1

Click the worksheet tab at the bottom of the screen that contains a range of precedent cells to which you want to link. A range is a block or group of adjacent cells. For example, assume you want to link a range of blank cells in “Sheet1” to a range of precedent cells in “Sheet2.” Click the “Sheet2” tab.

Step 2

Determine the precedent range’s width in columns and height in rows. In this example, assume cells A1 through A4 on “Sheet2” contain a list of numbers 1, 2, 3 and 4, respectively, which will be your precedent cells. This precedent range is one column wide by four rows high.

Step 3

Click the worksheet tab at the bottom of the screen that contains the blank cells in which you will insert a link. In this example, click the “Sheet1” tab.

Step 4

Select the range of blank cells you want to link to the precedent cells. This range must be the same size as the precedent range, but can be in a different location on the worksheet. Click and hold the mouse button on the top left cell of the range, drag the mouse cursor to the bottom right cell in the range and release the mouse button to select the range. In this example, assume you want to link cells C1 through C4 to the precedent range. Click and hold on cell C1, drag the mouse to cell C4 and release the mouse to highlight the range.

Step 5

Type “=,” the worksheet name containing the precedent cells, “!,” the top left cell of the precedent range, “:” and the bottom right cell of the precedent range. Press “Ctrl,” “Shift” and “Enter” simultaneously to complete the array formula. Each dependent cell is now linked to the cell in the precedent range that’s in the same respective location within the range. In this example, type “=Sheet2!A1:A4” and press “Ctrl,” “Shift” and “Enter” simultaneously. Cells C1 through C4 on “Sheet1” now contain the array formula “{=Sheet2!A1:A4}” surrounded by curly brackets, and show the same data as the precedent cells in “Sheet2.”

Good Luck !!!

Try this.(IE8+)

//Define function
function removeJsonAttrs(json,attrs){
    return JSON.parse(JSON.stringify(json,function(k,v){
        return attrs.indexOf(k)!==-1 ? undefined: v;
}));}
//use object
var countries = {};
countries.results = [
    {id:'AF',name:'Afghanistan'},
    {id:'AL',name:'Albania'},
    {id:'DZ',name:'Algeria'}
];
countries = removeJsonAttrs(countries,["name"]);
//use array
var arr = [
    {id:'AF',name:'Afghanistan'},
    {id:'AL',name:'Albania'},
    {id:'DZ',name:'Algeria'}
];
arr = removeJsonAttrs(arr,["name"]);

Kotlin

data class Player(val name : String, val surname: String)

val json = [
  {
    "name": "name 1",
    "surname": "surname 1"
  },
  {
    "name": "name 2",
    "surname": "surname 2"
  },
  {
    "name": "name 3",
    "surname": "surname 3"
  }
]

val typeToken = object : TypeToken<List<Player>>() {}.type
val playerArray = Gson().fromJson<List<Player>>(json, typeToken)

OR

val playerArray = Gson().fromJson(json, Array<Player>::class.java)

For a bit of a different approach you could use something like this on the list:

position: absolute;
top: 18px;
bottom: 0px;
width: 100%;

This works as long as the parent container has position: relative;

Try these styles:

p.event_desc {_x000D_
  font: bold 12px "Helvetica Neue", Helvetica, Arial, sans-serif;_x000D_
  line-height: 14px;_x000D_
  height:75px;_x000D_
  margin: 0px;_x000D_
  display: table-cell;_x000D_
  vertical-align: middle;_x000D_
  padding: 10px;_x000D_
  border: 1px solid #f00;_x000D_
}

<p class="event_desc">lorem ipsum</p>

For users of modern DataTables (1.10 and above), all the answers and examples on this page are for the old api, not the new. I had a very hard time finding a newer example but finally did find this DT forum post (TL;DR for most folks) which led me to this concise example.

The example code worked for me after I finally noticed the $() selector syntax immediately surrounding the html string. You have to add a node not a string.

That example really is worth looking at but, in the spirit of SO, if you just want to see a snippet of code that works:

var table = $('#example').DataTable();
  table.rows.add( $(
          '<tr>'+
          '  <td>Tiger Nixon</td>'+
          '  <td>System Architect</td>'+
          '  <td>Edinburgh</td>'+
          '  <td>61</td>'+
          '  <td>2011/04/25</td>'+
          '  <td>$3,120</td>'+
          '</tr>'
  ) ).draw();

The careful reader might note that, since we are adding only one row of data, that table.row.add(...) should work as well and did for me.

In case if you want to get the response of a function and set it into a variable, you can use it like the following in the template, using ng-container to avoid modifying the template.

<ng-container *ngIf="methodName(parameters) as respObject">
  {{respObject.name}}
</ng-container>

And the method in the component can be something like

methodName(parameters: any): any {
  return {name: 'Test name'};
}

This works using java.util.Scanner and will take multiple "enter" keystrokes:

    Scanner scanner = new Scanner(System.in);
    String readString = scanner.nextLine();
    while(readString!=null) {
        System.out.println(readString);

        if (readString.isEmpty()) {
            System.out.println("Read Enter Key.");
        }

        if (scanner.hasNextLine()) {
            readString = scanner.nextLine();
        } else {
            readString = null;
        }
    }

To break it down:

Scanner scanner = new Scanner(System.in);
String readString = scanner.nextLine();

These lines initialize a new Scanner that is reading from the standard input stream (the keyboard) and reads a single line from it.

    while(readString!=null) {
        System.out.println(readString);

While the scanner is still returning non-null data, print each line to the screen.

        if (readString.isEmpty()) {
            System.out.println("Read Enter Key.");
        }

If the "enter" (or return, or whatever) key is supplied by the input, the nextLine() method will return an empty string; by checking to see if the string is empty, we can determine whether that key was pressed. Here the text Read Enter Key is printed, but you could perform whatever action you want here.

        if (scanner.hasNextLine()) {
            readString = scanner.nextLine();
        } else {
            readString = null;
        }

Finally, after printing the content and/or doing something when the "enter" key is pressed, we check to see if the scanner has another line; for the standard input stream, this method will "block" until either the stream is closed, the execution of the program ends, or further input is supplied.

Create a $scope function that check it and returns true or false, like a "isEmpty" function and use in your view on ng-if statement like

ng-if="isEmpty(object)"

This worked for me

find /path/to/ -type f -print0 | xargs -0 file | grep -i image

This uses the file command to try to recognize the type of file, regardless of filename (or extension).

If /path/to or a filename contains the string image, then the above may return bogus hits. In that case, I'd suggest

cd /path/to
find . -type f -print0 | xargs -0 file --mime-type | grep -i image/

For me, it just was that service console restart didn't work after tomcat ran into an error. Only stop/start brought it back.

Try this:

$Date = $row['valdate']->format('d/m/Y'); // the result will 01/12/2015

as per 2018, the targetSdkVersion can be set up in your app/build.gradle the following way:

android {
    compileSdkVersion 26
    buildToolsVersion '27.0.3'

    defaultConfig {
       ...
       targetSdkVersion 26
    }

if you choose 26 as SDK target, be sure to follow https://developer.android.com/about/versions/oreo/android-8.0-migration

First of all go to the /home directorty then open invisible shell script with some text editor, ~/.bash_profile (macOS) or ~/.bashrc (linux) go to the bottom, you would see something like this,

export LD_LIBRARY_PATH = /usr/local/lib

change this like that( remove blank point around the = ),

export LD_LIBRARY_PATH=/usr/local/lib

it should be useful.

(Modified version to make it work without prototype.js)

function simulate(element, eventName)
{
    var options = extend(defaultOptions, arguments[2] || {});
    var oEvent, eventType = null;

    for (var name in eventMatchers)
    {
        if (eventMatchers[name].test(eventName)) { eventType = name; break; }
    }

    if (!eventType)
        throw new SyntaxError('Only HTMLEvents and MouseEvents interfaces are supported');

    if (document.createEvent)

            options.ctrlKey, options.altKey, options.shiftKey, options.metaKey, options.button, element);
        }
        element.dispatchEvent(oEvent);
    }
    else
    {
        options.clientX = options.pointerX;
        options.clientY = options.pointerY;
        var evt = document.createEventObject();
        oEvent = extend(evt, options);
        element.fireEvent('on' + eventName, oEvent);
    }
    return element;

    return destination;
}

var eventMatchers = {
    'HTMLEvents': /^(?:load|unload|abort|error|select|change|submit|reset|focus|blur|resize|scroll)$/,
    'MouseEvents': /^(?:click|dblclick|mouse(?:down|up|over|move|out))$/
}
var defaultOptions = {

    ctrlKey: false,
    altKey: false,
    shiftKey: false,
    metaKey: false,
    bubbles: true,
    cancelable: true
}

You can use it like this:

simulate(document.getElementById("btn"), "click");

Note that as a third parameter you can pass in 'options'. The options you don't specify are taken from the defaultOptions (see bottom of the script). So if you for example want to specify mouse coordinates you can do something like:

simulate(document.getElementById("btn"), "click", { pointerX: 123, pointerY: 321 })

You can use a similar approach to override other default options.

Or is sku a relationship to another model? If that is the case, then, as long as your relationship is setup properly, you code should work.

You could use the checked selector to grab only the selected ones (negating the need to know the count or to iterate over them all yourself):

$("input[name='user_group[]']:checked")

With those checked items, you can either create a collection of those values or do something to the collection:

var values = new Array();
$.each($("input[name='user_group[]']:checked"), function() {
  values.push($(this).val());
  // or you can do something to the actual checked checkboxes by working directly with  'this'
  // something like $(this).hide() (only something useful, probably) :P
});

This goes also for statements like this (auto-formatted by PyCharm):

    return combine_sample_generators(sample_generators['train']), \
           combine_sample_generators(sample_generators['dev']), \
           combine_sample_generators(sample_generators['test'])

Which will give the same style-warning. In order to get rid of it I had to rewrite it to:

    return \
        combine_sample_generators(sample_generators['train']), \
        combine_sample_generators(sample_generators['dev']), \
        combine_sample_generators(sample_generators['test'])

It looks like the CSRF (Cross Site Request Forgery) protection in your Spring application is enabled. Actually it is enabled by default.

According to spring.io:

When should you use CSRF protection? Our recommendation is to use CSRF protection for any request that could be processed by a browser by normal users. If you are only creating a service that is used by non-browser clients, you will likely want to disable CSRF protection.

So to disable it:

@Configuration
public class RestSecurityConfig extends WebSecurityConfigurerAdapter {
  @Override
  protected void configure(HttpSecurity http) throws Exception {
    http.csrf().disable();
  }
}

If you want though to keep CSRF protection enabled then you have to include in your form the csrftoken. You can do it like this:

<form .... >
  ....other fields here....
  <input type="hidden"  name="${_csrf.parameterName}"   value="${_csrf.token}"/>
</form>

You can even include the CSRF token in the form's action:

<form action="./upload?${_csrf.parameterName}=${_csrf.token}" method="post" enctype="multipart/form-data">

If you have the code to log_out(), rewrite it. Most likely, you can do:

static FILE *logfp = ...;

void log_out(const char *fmt, ...)
{
    va_list args;

    va_start(args, fmt);
    vfprintf(logfp, fmt, args);
    va_end(args);
}

If there is extra logging information needed, that can be printed before or after the message shown. This saves memory allocation and dubious buffer sizes and so on and so forth. You probably need to initialize logfp to zero (null pointer) and check whether it is null and open the log file as appropriate - but the code in the existing log_out() should be dealing with that anyway.

The advantage to this solution is that you can simply call it as if it was a variant of printf(); indeed, it is a minor variant on printf().

If you don't have the code to log_out(), consider whether you can replace it with a variant such as the one outlined above. Whether you can use the same name will depend on your application framework and the ultimate source of the current log_out() function. If it is in the same object file as another indispensable function, you would have to use a new name. If you cannot work out how to replicate it exactly, you will have to use some variant like those given in other answers that allocates an appropriate amount of memory.

void log_out_wrapper(const char *fmt, ...)
{
    va_list args;
    size_t  len;
    char   *space;

    va_start(args, fmt);
    len = vsnprintf(0, 0, fmt, args);
    va_end(args);
    if ((space = malloc(len + 1)) != 0)
    {
         va_start(args, fmt);
         vsnprintf(space, len+1, fmt, args);
         va_end(args);
         log_out(space);
         free(space);
    }
    /* else - what to do if memory allocation fails? */
}

Obviously, you now call the log_out_wrapper() instead of log_out() - but the memory allocation and so on is done once. I reserve the right to be over-allocating space by one unnecessary byte - I've not double-checked whether the length returned by vsnprintf() includes the terminating null or not.

formatDate is the function you can call it and pass the date you want to format to dd/mm/yyyy

var unformatedDate = new Date("2017-08-10 18:30:00");_x000D_
 _x000D_
$("#hello").append(formatDate(unformatedDate));_x000D_
function formatDate(nowDate) {_x000D_
 return nowDate.getDate() +"/"+ (nowDate.getMonth() + 1) + '/'+ nowDate.getFullYear();_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div id="hello">_x000D_
_x000D_
_x000D_
</div>

Just use this constructor of List<T>. It accepts any IEnumerable<T> as an argument.

string[] arr = ...
List<string> list = new List<string>(arr);

Bootstrap v4.1 uses new classnames for hiding columns on their grid system.

For hiding columns depending on the screen width, use d-none class or any of the d-{sm,md,lg,xl}-none classes. To show columns on certain screen sizes, combine the above mentioned classes with d-block or d-{sm,md,lg,xl}-block classes.

Examples are:

<div class="d-lg-none">hide on screens wider than lg</div>_x000D_
<div class="d-none d-lg-block">hide on screens smaller than lg</div>

More of these here.

In case you want to:

• also get the values for the keys
• check more than one dictonary

then:

from operator import itemgetter
foo = {'foo':1,'zip':2,'zam':3,'bar':4}
keys = ("foo","bar") 
getter = itemgetter(*keys) # returns all values
try:
    values = getter(foo)
except KeyError:
    # not both keys exist
    pass

Did you try:

$(this).is(':focus');

Take a look at Using jQuery to test if an input has focus it features some more examples

Today, in Office 365, Excel has so called 'array functions'. The filter function does exactly what you want. No need to use CTRL+SHIFT+ENTER anymore, a simple enter will suffice.

In Office 365, your problem would be simply solved by using:

=VLOOKUP(A3, FILTER(A2:C6, B2:B6="B"), 3, FALSE)

Without java code:

drawable/dotted.xml:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="line">

    <stroke
       android:color="#FF00FF"
       android:dashWidth="10px"
       android:dashGap="10px"
       android:width="1dp"/>
</shape>

view.xml:

<ImageView
    android:layout_width="match_parent"
    android:layout_height="5dp"
    android:src="@drawable/dotted"
    android:layerType="software" />

Effect:

Not sure if you have solved the problem. For this issue, you can use the "filter" function in the dplyr package. The idea is to filter the observations/rows whose values of the variable of your interest is not NA. Next, you make the graph with these filtered observations. You can find my codes below, and note that all the name of the data frame and variable is copied from the prompt of your question. Also, I assume you know the pipe operators.

library(tidyverse) 

MyDate %>%
   filter(!is.na(the_variable)) %>%
     ggplot(aes(x= the_variable, fill=the_variable)) + 
        geom_bar(stat="bin") 

You should be able to remove the annoying NAs on your plot. Hope this works :)

When Python2.x sees a == b, it tries the following.

• If type(b) is a new-style class, and type(b) is a subclass of type(a), and type(b) has overridden __eq__, then the result is b.__eq__(a).
• If type(a) has overridden __eq__ (that is, type(a).__eq__ isn't object.__eq__), then the result is a.__eq__(b).
• If type(b) has overridden __eq__, then the result is b.__eq__(a).
• If none of the above are the case, Python repeats the process looking for __cmp__. If it exists, the objects are equal iff it returns zero.
• As a final fallback, Python calls object.__eq__(a, b), which is True iff a and b are the same object.

If any of the special methods return NotImplemented, Python acts as though the method didn't exist.

Note that last step carefully: if neither a nor b overloads ==, then a == b is the same as a is b.

You can use this pod called 'SVGParser'. https://cocoapods.org/pods/SVGParser.

After adding it in your pod file, all you have to do is to import this module to the class that you want to use it. You should show the SVG image in an ImageView.

There are three cases you can show this SVGimage:

1. Load SVG from local path as Data
2. Load SVG from local path
3. Load SVG from remote URL

You can also find an example project in GitHub: https://github.com/AndreyMomot/SVGParser. Just download the project and run it to see how it works.

Unlike Java where you would declare boolean flag = True, in Python you can just declare myFlag = True

Python would interpret this as a boolean variable

This is a very strange request, and almost certainly something you'd never want to do in a real-world application, but from a purely academic standpoint it's an interesting challenge. With SQL Server 2005 you could use common table expressions and the row_number() functions and join on that:

with OrderedFoos as (
    select row_number() over (order by FooName) RowNum, *
    from Foos (nolock)
),
OrderedBars as (
    select row_number() over (order by BarName) RowNum, *
    from Bars (nolock)
)
select * 
from OrderedFoos f
    full outer join OrderedBars u on u.RowNum = f.RowNum

This works, but it's supremely silly and I offer it only as a "community wiki" answer because I really wouldn't recommend it.

The subject of the certificate is the entity its public key is associated with (i.e. the "owner" of the certificate).

As RFC 5280 says:

The subject field identifies the entity associated with the public key stored in the subject public key field. The subject name MAY be carried in the subject field and/or the subjectAltName extension.

X.509 certificates have a Subject (Distinguished Name) field and can also have multiple names in the Subject Alternative Name extension.

The Subject DN is made of multiple relative distinguished names (RDNs) (themselves made of attribute assertion values) such as "CN=yourname" or "O=yourorganization".

In the context of the article you're linking to, the subject would be the user/owner of the cert.

In Windows Just go to this path and clear it ,that works !!

findBy method in Symfony excepts two parameters. First is array of fields you want to search on and second array is the the sort field and its order

public function findSorted()
    {
        return $this->findBy(['name'=>'Jhon'], ['date'=>'DESC']);
    }

For Lumen:

Add to .env file

DB_ENGINE=InnoDB

It really all comes down to how you want to handle output that the command might return and whether you want your PHP script to wait for the callee program to finish or not.

• exec executes a command and passes output to the caller (or returns it in an optional variable).

• passthru is similar to the exec() function in that it executes a command . This function should be used in place of exec() or system() when the output from the Unix command is binary data which needs to be passed directly back to the browser.

• system executes an external program and displays the output, but only the last line.

If you need to execute a command and have all the data from the command passed directly back without any interference, use the passthru() function.

File from = new File(Environment.getExternalStorageDirectory().getAbsolutePath().getAbsolutePath()+"/kaic1/imagem.jpg");
File to = new File(Environment.getExternalStorageDirectory().getAbsolutePath()+"/kaic2/imagem.jpg");
from.renameTo(to);

Windows PowerShell provides two mechanisms for reporting errors: one mechanism for terminating errors and another mechanism for non-terminating errors.

Internal CmdLets code can call a ThrowTerminatingError method when an error occurs that does not or should not allow the cmdlet to continue to process its input objects. The script writter can them use exception to catch these error.

EX :

try
{
  Your database code
}
catch
{
  Error reporting/logging
}

Internal CmdLets code can call a WriteError method to report non-terminating errors when the cmdlet can continue processing the input objects. The script writer can then use -ErrorAction option to hide the messages, or use the $ErrorActionPreference to setup the entire script behaviour.

Since PostgreSQL 9.1, installation of additional modules is simple. Registered extensions like dblink can be installed with CREATE EXTENSION:

CREATE EXTENSION dblink;

Installs into your default schema, which is public by default. Make sure your search_path is set properly before you run the command. The schema must be visible to all roles who have to work with it. See:

• How does the search_path influence identifier resolution and the "current schema"

Alternatively, you can install to any schema of your choice with:

CREATE EXTENSION dblink SCHEMA extensions;

See:

• Best way to install hstore on multiple schemas in a Postgres database?

Run once per database. Or run it in the standard system database template1 to add it to every newly created DB automatically. Details in the manual.

You need to have the files providing the module installed on the server first. For Debian and derivatives this would be the package postgresql-contrib-9.1 - for PostgreSQL 9.1, obviously. Since Postgres 10, there is just a postgresql-contrib metapackage.

If the issue is a missing intermediate certificate, you can enable Oracle JRE to automatically download the missing intermediate certificate as explained in this answer.

Just set the Java system property -Dcom.sun.security.enableAIAcaIssuers=true

For this to work the server's certificate must provide the URI to the intermediate certificate (the certificate's issuer). As far as I can tell, this is what browsers do as well and should be just as secure - I'm not a security expert though.

Edit: If I recall correctly, this seems to work at least with Java 8 and is documented here for Java 9.

Facebook uses what's called the Open Graph Protocol to decide what things to display when you share a link. The OGP looks at your page and tries to decide what content to show. We can lend a hand and actually tell Facebook what to take from our page.

The way we do that is with og:meta tags.

The tags look something like this -

  <meta property="og:title" content="Stuffed Cookies" />
  <meta property="og:image" content="http://fbwerks.com:8000/zhen/cookie.jpg" />
  <meta property="og:description" content="The Turducken of Cookies" />
  <meta property="og:url" content="http://fbwerks.com:8000/zhen/cookie.html">

You'll need to place these or similar meta tags in the <head> of your HTML file. Don't forget to substitute the values for your own!

For more information you can read all about how Facebook uses these meta tags in their documentation. Here is one of the tutorials from there - https://developers.facebook.com/docs/opengraph/tutorial/

Facebook gives us a great little tool to help us when dealing with these meta tags - you can use the Debugger to see how Facebook sees your URL, and it'll even tell you if there are problems with it.

One thing to note here is that every time you make a change to the meta tags, you'll need to feed the URL through the Debugger again so that Facebook will clear all the data that is cached on their servers about your URL.

I used the EventWaitHandle class. On the parent process, create a named EventWaitHandle with initial state of the event set to non-signaled. The parent process blocks until the child process calls the Set method, changing the state of the event to signaled, as shown below.

Parent Process:

using System;
using System.Threading;
using System.Diagnostics;

namespace MyParentProcess
{
    class Program
    {
        static void Main(string[] args)
        {
            EventWaitHandle ewh = null;
            try
            {
                ewh = new EventWaitHandle(false, EventResetMode.AutoReset, "CHILD_PROCESS_READY");

                Process process = Process.Start("MyChildProcess.exe", Process.GetCurrentProcess().Id.ToString());

                        // Child process is ready.
                    }
                }
            }
            catch(Exception exception)
            { }
            finally

                    ewh.Close();
            }
        }
    }

Child Process:

using System.Threading;
using System.Diagnostics;

namespace MyChildProcess
{
    class Program
    {
        static void Main(string[] args)
        {
            try
            {
                // Representing some time consuming work.
                Thread.Sleep(5000);

                EventWaitHandle.OpenExisting("CHILD_PROCESS_READY")
                    .Set();

                Process.GetProcessById(Convert.ToInt32(args[0]))
                    .WaitForExit();
            }
            catch (Exception exception)
            { }
        }
    }
}

This message pops up, when the database user does not exist. Compare the manual here.
Multiple local databases cannot be the explanation. Roles are valid cluster-wide. The manual again:

Note that roles are defined at the database cluster level, and so are valid in all databases in the cluster.

You must be ending up in another database-cluster. That would be another server running on the same machine, listening to a different port. Or, more likely, on a different machine.

Could it be that the message comes, in fact, from the remote server?

You need both a value and a field to assign it to. The value is TableField + 1, so the assignment is:

SET TableField = TableField + 1

var userPasswordString = new Buffer(baseAuth, 'base64').toString('ascii');

Change this line from your code to this -

var userPasswordString = Buffer.from(baseAuth, 'base64').toString('ascii');

or in my case, I gave the encoding in reverse order

var userPasswordString = Buffer.from(baseAuth, 'utf-8').toString('base64');

This can be achieved using dplyr package, which is available in CRAN. The simple way to achieve this:

1. Install dplyr package.
2. Run the below code

library(dplyr) 

df<- select(filter(dat,name=='tom'| name=='Lynn'), c('days','name))

Explanation:

So, once we’ve downloaded dplyr, we create a new data frame by using two different functions from this package:

filter: the first argument is the data frame; the second argument is the condition by which we want it subsetted. The result is the entire data frame with only the rows we wanted. select: the first argument is the data frame; the second argument is the names of the columns we want selected from it. We don’t have to use the names() function, and we don’t even have to use quotation marks. We simply list the column names as objects.

MIN and MAX values of any integer data type can be computed without using any library functions as below and same logic can be applied to other integer types short, int and long.

printf("Signed Char : MIN -> %d & Max -> %d\n", ~(char)((unsigned char)~0>>1), (char)((unsigned char)~0 >> 1));
printf("Unsigned Char : MIN -> %u & Max -> %u\n", (unsigned char)0, (unsigned char)(~0));

I also had same error but with codeigniter application. I changed

• my base URL in config.php to my localhost path

• in htaccess I changed RewriteBase /"my folder name in htdocs"

  and I able to login to my application.

Hope it might help.

Date d=new Date(new Date().getTime()+28800000);
String s=new SimpleDateFormat("dd/MM/yyyy HH:mm:ss").format(d);

HH will return 0-23 for hours.

kk will return 1-24 for hours.

See more here: Customizing Formats

use method setIs24HourView(Boolean is24HourView) to set time picker to set 24 hour view.

I have two solutions for this Question.

1. The first solution is on getting display names from enum.

public enum CourseLocationTypes
{
    [Display(Name = "On Campus")]
    OnCampus,
    [Display(Name = "Online")]
    Online,
    [Display(Name = "Both")]
    Both
}

public static string DisplayName(this Enum value)
{
    Type enumType = value.GetType();
    string enumValue = Enum.GetName(enumType, value);
    MemberInfo member = enumType.GetMember(enumValue)[0];

    object[] attrs = member.GetCustomAttributes(typeof(DisplayAttribute), false);
    string outString = ((DisplayAttribute)attrs[0]).Name;

    if (((DisplayAttribute)attrs[0]).ResourceType != null)
    {
        outString = ((DisplayAttribute)attrs[0]).GetName();
    }

    return outString;
}

<h3 class="product-title white">@Model.CourseLocationType.DisplayName()</h3>

2. The second Solution is on getting display name from enum name but that will be enum split in developer language it's called patch.

public static string SplitOnCapitals(this string text)
{
        var r = new Regex(@"
            (?<=[A-Z])(?=[A-Z][a-z]) |
             (?<=[^A-Z])(?=[A-Z]) |
             (?<=[A-Za-z])(?=[^A-Za-z])", RegexOptions.IgnorePatternWhitespace);

        return r.Replace(text, " ");
}

 <div class="widget-box pt-0">
     @foreach (var item in Enum.GetNames(typeof(CourseLocationType)))
     {
         <label class="pr-2 pt-1">
             @Html.RadioButtonFor(x => x.CourseLocationType, item, new { type = "radio", @class = "iCheckBox control-label" })&nbsp; @item.SplitOnCapitals()
         </label>
     }
     @Html.ValidationMessageFor(x => x.CourseLocationType)
 </div>

I think some folks here haven't really focused on your particular question. It looks like the problem you have is in putting the random number in the page and hooking the player up to it. There are a number of ways to do that. The simplest is with a small change to your existing code like this to document.write() the result into the page. I wouldn't normally recommend document.write(), but since your code is already inline and what you were trying do already was to put the div inline, this is the simplest way to do that. At the point where you have the random number, you just use this to put it and the div into the page:

var randomId = "x" + randomString(8);
document.write('<div id="' + randomId + '">This text will be replaced</div>');

and then, you refer to that in the jwplayer set up code like this:

jwplayer(randomId).setup({

And the whole block of code would look like this:

<script type='text/javascript' src='jwplayer.js'></script>
<script type='text/javascript'>
function randomString(length) {
    var chars = '0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghiklmnopqrstuvwxyz'.split('');

    if (! length) {
        length = Math.floor(Math.random() * chars.length);
    }

    var str = '';
    for (var i = 0; i < length; i++) {
        str += chars[Math.floor(Math.random() * chars.length)];
    }
    return str;
}

var randomId = "x" + randomString(8);
document.write('<div id="' + randomId + '">This text will be replaced</div>'); 

  jwplayer(randomId).setup({
    'flashplayer': 'player.swf',
    'file': 'http://www.youtube.com/watch?v=4AX0bi9GXXY',
    'controlbar': 'bottom',
    'width': '470',
    'height': '320'
  });
</script>

Another way to do it

I might add here at the end that generating a truly random number just to create a unique div ID is way overkill. You don't need a random number. You just need an ID that won't otherwise exist in the page. Frameworks like YUI have such a function and all they do is have a global variable that gets incremented each time the function is called and then combine that with a unique base string. It can look something like this:

var generateID = (function() {
    var globalIdCounter = 0;
    return function(baseStr) {
        return(baseStr + globalIdCounter++);
    }
})();

And, then in practical use, you would do something like this:

var randomId = generateID("myMovieContainer");  // "myMovieContainer1"
document.write('<div id="' + randomId + '">This text will be replaced</div>');
jwplayer(randomId).setup({

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

execute sp_help table_name

I think that using a regular expression for this is faulty mainly due to

• The simplicity of the task
• Running a regular expression is always more cpu intensive/longer than cutting a string.

Since the url(" and ") components are constant, trim your string like so:

$("#id").click(function() {
     var bg = $(this).css('background-image').trim();
     var res = bg.substring(5, bg.length - 2);
     alert(res);
});

if (-e $base_path)
{ 
 # code
}

-e is the 'existence' operator in Perl.

You can check permissions and other attributes using the code on this page.

Set your HTML as

 <div id="body" hidden="">
 <h1>Numbers</h1>
 </div>
 <div id="body1" hidden="hidden">
 Body 1
 </div>

And now set the javascript as

     function changeDiv()
      {
      document.getElementById('body').hidden = "hidden"; // hide body div tag
      document.getElementById('body1').hidden = ""; // show body1 div tag
      document.getElementById('body1').innerHTML = "If you can see this, JavaScript function worked"; 
      // display text if JavaScript worked
       }

Check, it works.

Your code has two problems. One was identified and answered, but the other wasn't. The first was that your selector was missing the name of its parameter. However, even when you fix that, the line will still raise an exception, assuming your revised method signature still includes more than one argument. Let's say your revised method is declared as:

-(void)myTestWithString:(NSString *)sourceString comparedTo:(NSString *)testString ;

Creating selectors for methods that take multiple arguments is perfectly valid (e.g. @selector(myTestWithString:comparedTo:) ). However, the performSelector method only allows you to pass one value to myTest, which unfortunately has more than one parameter. It will error out and tell you that you didn't supply enough values.

You could always redefine your method to take a collection as it's only parameter:

-(void)myTestWithObjects:(NSDictionary *)testObjects ;

However, there is a more elegant solution (that doesn't require refactoring). The answer is to use NSInvocation, along with its setArgument:atIndex: and invoke methods.

I've written up an article, including a code example, if you want more details. The focus is on threading, but the basics still apply.

Good luck!

Very simple and surprisingly fast: (without numpy or pandas)

    str( myDate ) == 'NaT'            # True if myDate is NaT

Ok, it's a little nasty, but given the ambiguity surrounding 'NaT' it does the job nicely.

It's also useful when comparing two dates either of which might be NaT as follows:

   str( date1 ) == str( date1 )       # True
   str( date1 ) == str( NaT )         # False
   str( NaT )   == str( date1 )       # False

wait for it...

   str( NaT )   == str( Nat )         # True    (hooray!)

Because Java bytecode does not retain the names of method or constructor arguments.

Underscore-java library can convert Map to xml. I am the maintainer of the project. Live example

Code example:

import com.github.underscore.lodash.U;
import java.util.*;
    
public class Main {

  public static void main(String[] args) {
    
    Map<String, Object> map = new LinkedHashMap<String, Object>();
    map.put("name", "chris");
    map.put("island", "faranga");

    System.out.println(U.toXml(map));

    //  <?xml version="1.0" encoding="UTF-8"?>
    //  <root>
    //    <name>chris</name>
    //    <island>faranga</island>
    //  </root>

    // and back:
    map = U.fromXmlMap("<?xml version=\"1.0\" encoding=\"UTF-8\"?><root>"
        + "    <name>chris</name>"
        + "    <island>faranga</island>"
        + "  </root>");
        
    System.out.println(map);
    // {name=chris, island=faranga}
  }
}

Here is how I do it:

    var hashTagActive = "";
    $(".scroll").on("click touchstart" , function (event) {
        if(hashTagActive != this.hash) { //this will prevent if the user click several times the same link to freeze the scroll.
            event.preventDefault();
            //calculate destination place
            var dest = 0;
            if ($(this.hash).offset().top > $(document).height() - $(window).height()) {
                dest = $(document).height() - $(window).height();
            } else {
                dest = $(this.hash).offset().top;
            }
            //go to destination
            $('html,body').animate({
                scrollTop: dest
            }, 2000, 'swing');
            hashTagActive = this.hash;
        }
    });

Then you just need to create your anchor like this:

<a class="scroll" href="#destination1">Destination 1</a>

You can see it on my website.

I viewed the Eclipse ADT documentation and found out the way to get around this issue. I was able to Update My SDK Tool to 22.0.4 (Latest Version).

Solution is: First Update ADT to 22.0.4 and then Update SDK Tool to 22.0.4

The above link says,

ADT 22.0.4 is designed for use with SDK Tools r22.0.4. If you haven't already installed SDK Tools r22.0.4 into your SDK, use the Android SDK Manager to do so

What I had to do was update my ADT to 22.0.4 (Latest Version) and then I was able to update SDK tool to 22.0.4. I thought only SDK Tool has been updated not ADT, so I was updating the SDK Tool with Older ADT Version (22.0.1).

How to Update your ADT to Latest Version

1. In Eclipse go to Help

2. Install New Software ---> Add

3. inside Add Repository write the Name: ADT (or whatever you want)

4. Location: https://dl-ssl.google.com/android/eclipse/

5. after loading you should get Developer Tools and NDK Plugins

6. check both if you want to use the Native Developer Kit (NDK) in the future or check

7. Developer Tool only

8. click Next

9. Finish

What's dumpsys and what are its benefit

dumpsys is an android tool that runs on the device and dumps interesting information about the status of system services.

Obvious benefits:

1. Possibility to easily get system information in a simple string representation.
2. Possibility to use dumped CPU, RAM, Battery, storage stats for a pretty charts, which will allow you to check how your application affects the overall device!

What information can we retrieve from dumpsys shell command and how we can use it

If you run dumpsys you would see a ton of system information. But you can use only separate parts of this big dump.

to see all of the "subcommands" of dumpsys do:

If you want see the info for all processes, use ~$ adb shell dumpsys meminfo

dumpsys is ultimately flexible and useful tool!

If you want to use this tool do not forget to add permission into your android manifest automatically android.permission.DUMP

Try to test all commands to learn more about dumpsys. Happy dumping!

The simplest way is this:

while (cursor.moveToNext()) {
    ...
}

The cursor starts before the first result row, so on the first iteration this moves to the first result if it exists. If the cursor is empty, or the last row has already been processed, then the loop exits neatly.

Of course, don't forget to close the cursor once you're done with it, preferably in a finally clause.

Cursor cursor = db.rawQuery(...);
try {
    while (cursor.moveToNext()) {
        ...
    }
} finally {
    cursor.close();
}

If you target API 19+, you can use try-with-resources.

try (Cursor cursor = db.rawQuery(...)) {
    while (cursor.moveToNext()) {
        ...
    }
}

You can set the Property FormBorderStyle to none in the designer, or in code:

this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;

If you are using Bundler 1.1 or later you can use bundle clean, just as you imagined you could. This is redundant if you're using bundle install --path (Bundler manages the location you specified with --path, so takes responsibility for removing outdated gems), but if you've used Bundler to install the gems as system gems then bundle clean --force will delete any system gems not required by your Gemfile. Blindingly obvious caveat: don't do this if you have other apps that rely on system gems that aren't in your Gemfile!

Pat Shaughnessy has a good description of bundle clean and other new additions in bundler 1.1.

 String input = "abbcccaabbddeessacccbbddefgaabbccddeeffggadscsda";
    String output ="";

    for (int i= 0; i<input.length();i++) {
        if (!output.contains(input.substring(i, i+1))) 
            output = output+ input.substring(i, i+1);

    }


        System.out.println(output);

Ive modifiet Lukas Knuth's solution a little:

1) There's no need to subclass the webview,

2) the code will crash during bytecode verification on some Android 1.6 devices if you don't put nonexistant methods in seperate classes

3) Zoom controls will still appear if the user scrolls up/down a page. I simply set the zoom controller container to visibility GONE

  wv.getSettings().setSupportZoom(true);
  wv.getSettings().setBuiltInZoomControls(true);
  if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.HONEYCOMB) {
    // Use the API 11+ calls to disable the controls
    // Use a seperate class to obtain 1.6 compatibility
    new Runnable() {
      public void run() {
        wv.getSettings().setDisplayZoomControls(false);
      }
    }.run();
  } else {
    final ZoomButtonsController zoom_controll =
        (ZoomButtonsController) wv.getClass().getMethod("getZoomButtonsController").invoke(wv, null);
    zoom_controll.getContainer().setVisibility(View.GONE);
  }

I'm adding a code snippet which shows on how to post a file to an API which has been exposed over DELETE http verb. This is not a common case to upload a file with DELETE http verb but it is allowed. I've assumed Windows NTLM authentication for authorizing the call.

The problem that one might face is that all the overloads of HttpClient.DeleteAsync method have no parameters for HttpContent the way we get it in PostAsync method

var requestUri = new Uri("http://UrlOfTheApi");
using (var streamToPost = new MemoryStream("C:\temp.txt"))
using (var fileStreamContent = new StreamContent(streamToPost))
using (var httpClientHandler = new HttpClientHandler() { UseDefaultCredentials = true })
using (var httpClient = new HttpClient(httpClientHandler, true))
using (var requestMessage = new HttpRequestMessage(HttpMethod.Delete, requestUri))
using (var formDataContent = new MultipartFormDataContent())
{
    formDataContent.Add(fileStreamContent, "myFile", "temp.txt");
    requestMessage.Content = formDataContent;
    var response = httpClient.SendAsync(requestMessage).GetAwaiter().GetResult();

    if (response.IsSuccessStatusCode)
    {
        // File upload was successfull
    }
    else
    {
        var erroResult = response.Content.ReadAsStringAsync().GetAwaiter().GetResult();
        throw new Exception("Error on the server : " + erroResult);
    }
}

You need below namespaces at the top of your C# file:

using System;
using System.Net;

P.S. Sorry about so many using blocks(IDisposable pattern) in my code. Unfortunately, the syntax of using construct of C# doesn't support initializing multiple variables in single statement.

Change the profiles parameter to "commandline": "%PROGRAMFILES%\\Git\\bin\\bash.exe -l -i"

This works for me and allows for my .bash_profile alias autocomplete scripts to run.

I had the same issue for a while and had a very hard time figuring it out. My problem was that I had the site working for a while with the sessions working right, and then all of the sudden everything broke.

Apparently, your session_save_path(), for me it was /var/lib/php5/, needs to have correct permissions (the user running php, eg www-data needs write access to the directory). I accidentally changed it, breaking sessions completely.

Run sudo chmod -R 700 /var/lib/php5/ and then sudo chown -R www-data /var/lib/php5/ so that the php user has access to the folder.

I find the "parseInt" suggestions to be pretty curious, because "parseInt" operates on strings by design. That's why its name has the word "parse" in it.

A trick that avoids a function call entirely is

var truncated = ~~number;

The double application of the "~" unary operator will leave you with a truncated version of a double-precision value. However, the value is limited to 32 bit precision, as with all the other JavaScript operations that implicitly involve considering numbers to be integers (like array indexing and the bitwise operators).

edit — In an update quite a while later, another alternative to the ~~ trick is to bitwise-OR the value with zero:

var truncated = number|0;

Get All Keys In Redis

Get all keys using the --scan option:

$ redis-cli --scan --pattern '*'

List all keys using the KEYS command:

$ redis-cli KEYS '*'

There's a couple of ways to accomplish this decently efficiently.

First -
If possible, you can do some sort of bulk insert to a temporary table. This depends somewhat on your RDBMS/host language, but at worst this can be accomplished with a simple dynamic SQL (using a VALUES() clause), and then a standard update-from-another-table. Most systems provide utilities for bulk load, though

Second -
And this is somewhat RDBMS dependent as well, you could construct a dynamic update statement. In this case, where the VALUES(...) clause inside the CTE has been created on-the-fly:

WITH Tmp(id, px, py) AS (VALUES(id1, newsPosX1, newPosY1), 
                               (id2, newsPosX2, newPosY2),
                               ......................... ,
                               (idN, newsPosXN, newPosYN))

UPDATE TableToUpdate SET posX = (SELECT px
                                 FROM Tmp
                                 WHERE TableToUpdate.id = Tmp.id),
                         posY = (SELECT py
                                 FROM Tmp
                                 WHERE TableToUpdate.id = Tmp.id)


WHERE id IN (SELECT id
             FROM Tmp)

(According to the documentation, this should be valid SQLite syntax, but I can't get it to work in a fiddle)

My solution is to use ggplot2. It takes care of these types of things automatically. The biggest thing is to arrange the data appropriately.

y1 <- c(100, 200, 300, 400, 500)
y2 <- c(1, 2, 3, 4, 5)
x <- c(1, 2, 3, 4, 5)
df <- data.frame(x=rep(x,2), y=c(y1, y2), class=c(rep("y1", 5), rep("y2", 5)))

Then use ggplot2 to plot it

library(ggplot2)
ggplot(df, aes(x=x, y=y, color=class)) + geom_point()

This is saying plot the data in df, and separate the points by class.

The plot generated is

The python libs are obsolete with this function. I've done one that works correctly:

import os
import shutil

def copydirectorykut(src, dst):
    os.chdir(dst)
    list=os.listdir(src)
    nom= src+'.txt'
    fitx= open(nom, 'w')

    for item in list:
        fitx.write("%s\n" % item)

    fitx.close()

    f = open(nom,'r')
    for line in f.readlines():
        if "." in line:
            shutil.copy(src+'/'+line[:-1],dst+'/'+line[:-1])
        else:
            if not os.path.exists(dst+'/'+line[:-1]):
                os.makedirs(dst+'/'+line[:-1])
                copydirectorykut(src+'/'+line[:-1],dst+'/'+line[:-1])
            copydirectorykut(src+'/'+line[:-1],dst+'/'+line[:-1])
    f.close()
    os.remove(nom)
    os.chdir('..')

If you are using Angular 8+ and you want to reduce the size of the bundle you can use Ivy. Ivy comes as the default view engine in Angular 9 Just go to src/tsconfig.app.json and add the angularCompilerOptions parameter, for example:

{
  "extends": ...,
  "compilerOptions":...,
  "exclude": ...,

/* add this one */ 
  "angularCompilerOptions": {
    "enableIvy": true
  }
}

It isn't possible as far as I can tell, since a link needs HTML, and mailto links don't create an HTML email.

This is probably for security as you could add javascript or iframes to this link and the email client might open up the end user for vulnerabilities.

my css

TR.gray-t {background:#949494;}
h3{
    padding-top:3px;
    font:bold 12px/2px Arial;
}

my html

<TR class='gray-t'>
<TD colspan='3'><h3>KAJANG</h3>

I decrease the 2nd size in font.

padding-top is used to fix the size in IE7.

My solution,

load the app using

NODE_ENV=production node app.js

Then setup config.js as a function rather than an object

module.exports = function(){
    switch(process.env.NODE_ENV){
        case 'development':
            return {dev setting};

        case 'production':
            return {prod settings};

        default:
            return {error or other settings};
    }
};

Then as per Jans solution load the file and create a new instance which we could pass in a value if needed, in this case process.env.NODE_ENV is global so not needed.

var Config = require('./conf'),
    conf = new Config();

Then we can access the config object properties exactly as before

conf.twitter.consumerKey

One option that might work is using WindowsIdentity.Impersonate (and change the thread principal) to become the desired user, like so. Back to p/invoke, though, I'm afraid...

Another cheeky (and equally far from ideal) option might be to spawn a process to do the work... ProcessStartInfo accepts a .UserName, .Password and .Domain.

Finally - perhaps run the service in a dedicated account that has access? (removed as you have clarified that this isn't an option).

In my case the bean has been initialized using @Autowired annotation instead of @MockBean

So in this way mocking of DAOs and Services throws such exception

See here: Physical Vs Virtual Memory

Virtual memory is stored on the hard drive and is used when the RAM is filled. Physical memory is limited to the size of the RAM chips installed in the computer. Virtual memory is limited by the size of the hard drive, so virtual memory has the capability for more storage.

Another option is :

For me, something different worked, that I found in on this answer from a similar question. Probably won't help OP, but maybe someone like me that had a similar problem.

You should indeed use rvm, but as no one explained to you how to do this without rvm, here you go:

sudo gem install tzinfo builder memcache-client rack rack-test rack-mount \
  abstract erubis activesupport mime-types mail text-hyphen text-format   \
  thor i18n rake bundler arel railties rails --prerelease --force

The best way i found is to override the "ProcessDialogKey" function. This way canceling a open control is still possible because the function is only called when no other control uses the pressed Key.

This is the same behaviour as when setting a CancelButton. Using the KeyDown Event fires always and thus the form would close even when it should cancel the edit of an open editor.

protected override bool ProcessDialogKey(Keys keyData)
{
    if (Form.ModifierKeys == Keys.None && keyData == Keys.Escape)
    {
        this.Close();
        return true;
    }
    return base.ProcessDialogKey(keyData);
}

You can use the jQuery ajax method link if you want to pass data from client to server. In this case you can use $_SERVER['HTTP_USER_AGENT'] variable to found browser user agent.

Use the below link for wrap into two lines check the link

Insert ellipsis (...) into HTML tag if content too wide

That needs the below jquery

Building on the other answers, I wanted to share an example of using the while loop construct to achieve a do-while behaviour. By using a simple boolean variable in the while condition (initialized to TRUE), and then checking our actual condition later in the if statement. One could also use a break keyword instead of the continue <- FALSE inside the if statement (probably more efficient).

  df <- data.frame(X=c(), R=c())  
  x <- x0
  continue <- TRUE

  while(continue)
  {
    xi <- (11 * x) %% 16
    df <- rbind(df, data.frame(X=x, R=xi))
    x <- xi

    if(xi == x0)
    {
      continue <- FALSE
    }
  }

Of course there are many approaches like synchronous request, promise, but from my experience I think you should use the callback approach. It's natural to asynchronous behavior of Javascript. So, your code snippet can be rewrite a little different:

function foo() {
    var result;

    $.ajax({
        url: '...',
        success: function(response) {
            myCallback(response);
        }
    });

    return result;
}

function myCallback(response) {
    // Does something.
}

I attempted to use the toggleClass method to hide an item on my site (using visibility:hidden as opposed to display:none) with a slight animation, but for some reason the animation would not work (possibly due to an older version of jQuery UI).

The class was removed and added correctly, but the duration I added did not seem to make any difference - the item was simply added or removed with no effect.

So to resolve this I used a second class in my toggle method and applied a CSS transition instead:

The CSS:

.hidden{
    visibility:hidden;
    opacity: 0;
    -moz-transition: opacity 1s, visibility 1.3s;
    -webkit-transition: opacity 1s, visibility 1.3s;
    -o-transition: opacity 1s, visibility 1.3s;
    transition: opacity 1s, visibility 1.3s;
}
.shown{
    visibility:visible;
    opacity: 1;
    -moz-transition: opacity 1s, visibility 1.3s;
    -webkit-transition: opacity 1s, visibility 1.3s;
    -o-transition: opacity 1s, visibility 1.3s;
    transition: opacity 1s, visibility 1.3s;
}

The JS:

    function showOrHide() {
        $('#element').toggleClass("hidden shown");
    }

Thanks @tomas.satinsky for the awesome (and super simple) answer on this post.

You should be able to use the format method:

"Location: {0:20} Revision {1}".format(Location,Revision)

You will have to figure out the of the format length for each line depending on the length of the label. The User line will need a wider format width than the Location or District lines.

actually @bazzlebrush 's answer and @filoxo 's comment helped me a lot.

I needed to find the elements where the class could be "zA yO" OR "zA zE"

Using jquery I first select the parent of the desired elements:

(a div with class starting with 'abc' and style != 'display:none')

var tom = $('div[class^="abc"][style!="display: none;"]')[0];                   

then the desired children of that element:

var ax = tom.querySelectorAll('.zA.yO, .zA.zE');

works perfectly! note you don't have to do document.querySelector you can as above pass in a pre-selected object.

I answered this somewhere else . However, here are two function you might want to call on keyup event.

To capitalize first word

  function ucfirst(str,force){
          str=force ? str.toLowerCase() : str;
          return str.replace(/(\b)([a-zA-Z])/,
                   function(firstLetter){
                      return   firstLetter.toUpperCase();
                   });
     }

And to capitalize all words

function ucwords(str,force){
  str=force ? str.toLowerCase() : str;  
  return str.replace(/(\b)([a-zA-Z])/g,
           function(firstLetter){
              return   firstLetter.toUpperCase();
           });
}

As @Darrell Suggested

$('input[type="text"]').keyup(function(evt){

      // force: true to lower case all letter except first
      var cp_value= ucfirst($(this).val(),true) ;

      // to capitalize all words  
      //var cp_value= ucwords($(this).val(),true) ;


      $(this).val(cp_value );

   });

Hope this is helpful

Cheers :)

I had a similar problem and in my case, the issue was different (I am using Django templates).

The order of JS was incorrect (I know that's the first thing you check but I was almost sure that that was not the case, but it was). The js calling the dialog was called before jqueryUI library was called.

I am using Django, so was inheriting a template and using {{super.block}} to inherit code from the block as well to the template. I had to move {{super.block}} at the end of the block which solved the issue. The js calling the dialog was declared in the Media class in Django's admin.py. I spent more than an hour to figure it out. Hope this helps someone.

Check out some of the answers to this question - I think it might apply to yours:

how to run click function after default behaviour of a element

I think you're running into an inconsistency in the browser implementation of the onclick function. Some choose to toggle the checkbox before the event is fired and some after.

It is often required to move both body and html objects together.

$('html,body').animate({
   scrollTop: $("#divToBeScrolledTo").offset().top
});

ShiftyThomas is right:

$("#divToBeScrolledTo").offset().top + 10 // +10 (pixels) reduces the margin.

So to increase the margin use:

$("#divToBeScrolledTo").offset().top - 10 // -10 (pixels) would increase the margin between the top of your window and your element.

For some reason, even if changing the iOS Deployment Target to 8.0 or higher, the Xib files don't adopt that change and remain with the previous settings in the File inspector

Therefore, you should change it manually for each Xib

Once done, the warning will disappear :-)

First I did alias setup on bash / zsh profile.

alias composer="php /usr/local/bin/composer.phar"

Then I moved composer.phar to /usr/local/bin/

cd /usr/local/bin
mv composer.phar composer

Then made composer executable by running

sudo chmod +x composer

document.getElementById('drpSelectSourceLibrary').value = 'Seven';

There are lots of options out there. Many of which are available as downloadable software as well as public websites. I do not think many of them expect to be used as API's unless they explicitly state that.

The one that I found effective was Enju which did not have the character limit that the Marc's Carnagie Mellon link had. Marc also mentioned a VISL scanner in comments, but that requires java in the browser, which is a non-starter for me.

Note that recently, Google has offered a new NLP Machine Learning API that providers amoung other features, a automatic sentence parser. I will likely not update this answer again, especially since the question is closed, but I suspect that the other big ML cloud stacks will soon support the same.

<style name="MineCustomTabText" parent="TextAppearance.Design.Tab">
    <item name="android:textSize">16sp</item>
</style>

Use is in TabLayout like this

<android.support.design.widget.TabLayout
            app:tabTextAppearance="@style/MineCustomTabText"
            ...
            />

Update: Given that this post is quite old, and I've modified this utility a lot for my own use during that time, I thought I should post a new version. My newest code can be found on The MathWorks File Exchange: dirPlus.m. You can also get the source from GitHub.

I made a number of improvements. It now gives you options to prepend the full path or return just the file name (incorporated from Doresoom and Oz Radiano) and apply a regular expression pattern to the file names (incorporated from Peter D). In addition, I added the ability to apply a validation function to each file, allowing you to select them based on criteria other than just their names (i.e. file size, content, creation date, etc.).

NOTE: In newer versions of MATLAB (R2016b and later), the dir function has recursive search capabilities! So you can do this to get a list of all *.m files in all subfolders of the current folder:

dirData = dir('**/*.m');

Old code: (for posterity)

Here's a function that searches recursively through all subdirectories of a given directory, collecting a list of all file names it finds:

function fileList = getAllFiles(dirName)

  dirData = dir(dirName);      %# Get the data for the current directory
  dirIndex = [dirData.isdir];  %# Find the index for directories
  fileList = {dirData(~dirIndex).name}';  %'# Get a list of the files
  if ~isempty(fileList)
    fileList = cellfun(@(x) fullfile(dirName,x),...  %# Prepend path to files
                       fileList,'UniformOutput',false);
  end
  subDirs = {dirData(dirIndex).name};  %# Get a list of the subdirectories
  validIndex = ~ismember(subDirs,{'.','..'});  %# Find index of subdirectories
                                               %#   that are not '.' or '..'
  for iDir = find(validIndex)                  %# Loop over valid subdirectories
    nextDir = fullfile(dirName,subDirs{iDir});    %# Get the subdirectory path
    fileList = [fileList; getAllFiles(nextDir)];  %# Recursively call getAllFiles
  end

end

After saving the above function somewhere on your MATLAB path, you can call it in the following way:

fileList = getAllFiles('D:\dic');

Also possible to use DownloadData method

    private byte[] GetImage(string iconPath)
    {
        using (WebClient client = new WebClient())
        {
            byte[] pic = client.DownloadData(iconPath);
            //string checkPath = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments) +@"\1.png";
            //File.WriteAllBytes(checkPath, pic);
            return pic;
        }
    }

Here is slightly modified version. Changes are noted as code commentary.

Line break accepts an optional argument in brackets, a vertical length:

line 1
\\[4in]
line 2

To make this more scalable with respect to font size, you can use other lengths, such as \\[3\baselineskip], or \\[3ex].

first, you have to create a handler.

var specialElementHandlers = {
    '#editor': function(element, renderer){
        return true;
    }
};

then write this code in click event:

doc.fromHTML($('body').get(0), 15, 15, {
    'width': 170, 
    'elementHandlers': specialElementHandlers
        });

var pdfOutput = doc.output();
            console.log(">>>"+pdfOutput );

assuming you've already declared doc variable. And Then you have save this pdf file using File-Plugin.

As Mehrdad said, you cannot just seek to the n-th line without reading the file. However, you don't need to store the entire file in memory - just discard the data you don't need.

string line;
using (StreamReader sr = new StreamReader(path))
    for (int i = 0; i<15; i++)
    {
       line = sr.ReadLine();
       if (line==null) break; // there are less than 15 lines in the file
    }

On a SpringBoot project using IntelliJ and Gradle, I got the warning "Deprecated Gradle features were used in this build, making it incompatible with Gradle 5.0" when running my integration test. What solved the problem was: - Going to: File > Settings > Build, Execution, Deployment - Selecting for "Build and run using": Intellij IDEA (instead of "Gradle") - Same for "Run tests using" That did not explain why Gradle is displaying the warning, but that let me perform the test and progress in my work.

Btw, the reason that you're having trouble is that the java compiler recognizes two version flags. There is -source 1.5, which assumes java 1.5 level source code, and -target 1.5, which will emit java 1.5 compatible class files. You'll probably want to use both of these switches, but you definitely need -target 1.5; try double checking that eclipse is doing the right thing.

you need to add Content-Length: 0 in your request header.

a very descriptive example of how to test is given here

useState is one of the hooks available in React v16.8.0. It basically lets you turn your otherwise non-stateful/functional components to one that can have its own state.

At the very basic level, it's used this way:

const [isLoading, setLoading] = useState(true);

This then lets you call setLoading passing a boolean value. It's a cool way of having "stateful" functional component.

+= is the in-place addition operator.

It's the same as doing cnt = cnt + 1. For example:

>>> cnt = 0
>>> cnt += 2
>>> print cnt
2
>>> cnt += 42
>>> print cnt
44

The operator is often used in a similar fashion to the ++ operator in C-ish languages, to increment a variable by one in a loop (i += 1)

There are similar operator for subtraction/multiplication/division/power and others:

i -= 1 # same as i = i - 1
i *= 2 # i = i * 2
i /= 3 # i = i / 3
i **= 4 # i = i ** 4

The += operator also works on strings, for example:

>>> s = "Hi"
>>> s += " there"
>>> print s
Hi there

People tend to recommend against doing this for performance reason, but for the most scripts this really isn't an issue. To quote from the "Sequence Types" docs:

6. If s and t are both strings, some Python implementations such as CPython can usually perform an in-place optimization for assignments of the form s=s+t or s+=t. When applicable, this optimization makes quadratic run-time much less likely. This optimization is both version and implementation dependent. For performance sensitive code, it is preferable to use the str.join() method which assures consistent linear concatenation performance across versions and implementations.

The str.join() method refers to doing the following:

mysentence = []
for x in range(100):
    mysentence.append("test")
" ".join(mysentence)

..instead of the more obvious:

mysentence = ""
for x in range(100):
    mysentence += " test"

The problem with the later is (aside from the leading-space), depending on the Python implementation, the Python interpreter will have to make a new copy of the string in memory every time you append (because strings are immutable), which will get progressively slower the longer the string to append is.. Whereas appending to a list then joining it together into a string is a consistent speed (regardless of implementation)

If you're doing basic string manipulation, don't worry about it. If you see a loop which is basically just appending to a string, consider constructing an array, then "".join()'ing it.

This solves the problem:

df['newcolumn'] = df.A * df.B

You could also do:

def fab(row):
  return row['A'] * row['B']

df['newcolumn'] = df.apply(fab, axis=1)

I've ran across this problem recently while trying to retrieve a null decimal from a DataTable object from db and I haven't seen this answer here. I find this easier and shorter:

var value = rdrSelect.Field<decimal?>("ColumnName") ?? 0;

This was useful in my case since i didn't have a nullable decimal in the model, but needed a quick check against one. If the db value happens to be null, it'll just assign the default value.

I used zxing-1.3 jar and I had to make some changes implementing code from other answers, so I will leave my solution for others. I did the following:

1) find zxing-1.3.jar, download it and add in properties (add external jar).

2) in my activity layout add ImageView and name it (in my example it was tnsd_iv_qr).

3) include code in my activity to create qr image (in this example I was creating QR for bitcoin payments):

    QRCodeWriter writer = new QRCodeWriter();
    ImageView tnsd_iv_qr = (ImageView)findViewById(R.id.tnsd_iv_qr);
    try {
        ByteMatrix bitMatrix = writer.encode("bitcoin:"+btc_acc_adress+"?amount="+amountBTC, BarcodeFormat.QR_CODE, 512, 512);
        int width = 512;
        int height = 512;
        Bitmap bmp = Bitmap.createBitmap(width, height, Bitmap.Config.RGB_565);
        for (int x = 0; x < width; x++) {
            for (int y = 0; y < height; y++) {
                if (bitMatrix.get(x, y)==0)
                    bmp.setPixel(x, y, Color.BLACK);
                else
                    bmp.setPixel(x, y, Color.WHITE);
            }
        }
        tnsd_iv_qr.setImageBitmap(bmp);
    } catch (WriterException e) {
        //Log.e("QR ERROR", ""+e);

    }

If someone is wondering, variable "btc_acc_adress" is a String (with BTC adress), amountBTC is a double, with, of course, transaction amount.

Perhaps That Helps?

Some of the answers above, in regards to linux, are either incomplete, or flat out wrong.

For example, /usr/include/GL/gl.h is not part of mesa-common-dev or has not been for many years.

At any rate, for a more current answer, these two packages are important:

https://mesa.freedesktop.org/archive/mesa-20.1.2.tar.xz

ftp://ftp.freedesktop.org/pub/mesa/glu/glu-9.0.1.tar.xz

The glu.h is part of glu itself:

GL/glu.h
GL/glu_mangle.h

Mesa is evidently significantly larger. Its headers are a bit variable, I suppose, depending on the flags given to meson, but should include these typically:

Hope that helps anyone finding an answer this question in the future; compiling dosbox needs this, for instance, due to SDL opengl.

Is this what you're looking for?:

:"Book Author Title"

:)

Deleting the ~/.m2/repository will solve your problem. But, if you still need to keep the old ~/.m2/repository you can just change the maven local path temporarily.

If you are working on IntelliJ just go to Maven Settings and change the Local Repository path to somewhere else. You may need to tick the override checkbox near there.

You are thinking in the function ABS, that gives you the absolute value of numeric data.

SELECT ABS(a) AS AbsoluteA, ABS(b) AS AbsoluteB
FROM YourTable

a bit late, but it might be worth checking the "indicator" parameter of pd.merge.

See this other question for an example: Compare PandaS DataFrames and return rows that are missing from the first one

I have encountered the same error while trying to execute a script file created in windows OS using textpad. so that one can select proper file format like unix/mac etc.. or recreate the script in linux iteself.

What worked for me on Mint 17.03 which is base off Ubuntu 14.04

sudo add-apt-repository ppa:cwchien/gradle sudo apt-get update sudo apt-get install gradle

Reopen Android Studio. Go to Run/Debug Configuration and there should be an icon saying you need to Update gradle. Just click it.

Other answers are outdated, or incomplete, or simply don't work.

You need to also specify an X-11 server on the host machine to handle the launch of GUId programs. If the client is a Windows machine install Xming. If the client is a Linux machine install XQuartz.

Now suppose this is Windows connecting to Linux. In order to be able to launch X11 programs as well over putty do the following:

- Launch XMing on Windows client
- Launch Putty
    * Fill in basic options as you know in session category
    * Connection -> SSH -> X11
        -> Enable X11 forwarding
        -> X display location = :0.0
        -> MIT-Magic-Cookie-1
        -> X authority file for local display = point to the Xming.exe executable

Of course the ssh server should have permitted Desktop Sharing "Allow other user to view your desktop".

MobaXterm and other complete remote desktop programs work too.

IF EXISTS(SELECT TOP 1 1 FROM sys.default_constraints WHERE parent_object_id = OBJECT_ID(N'[dbo].[ChannelPlayerSkins]') AND name = 'FK_ChannelPlayerSkins_Channels')
BEGIN
    DROP CONSTRAINT FK_ChannelPlayerSkins_Channels
END
GO

You can also patern :

DF[DF.col.str.contains(pat = '(foo)', regex = True) ]

You can check and take the implementation of the class StickyHeaderHelper in my FlexibleAdapter project, and adapt it to your use case.

But, I suggest to use the library since it simplifies and reorganizes the way you usually implement the Adapters for RecyclerView: Don't reinvent the wheel.

I would also say, don't use Decorators or deprecated libraries, as well as don't use libraries that do only 1 or 3 things, you will have to merge implementations of others libraries yourself.

In case it helps someone, if your variables have hyphens in them, you may see this error since hyphens are not allowed in variable names in Python and are used as subtraction operators.

Example:

my-variable = 5   # would result in 'SyntaxError: can't assign to operator'

demo change type of field mid from string to mongo objectId using mongoose

 Post.find({}, {mid: 1,_id:1}).exec(function (err, doc) {
             doc.map((item, key) => {
                Post.findByIdAndUpdate({_id:item._id},{$set:{mid: mongoose.Types.ObjectId(item.mid)}}).exec((err,res)=>{
                    if(err) throw err;
                    reply(res);
                });
            });
        });

Mongo ObjectId is just another example of such styles as

Number, string, boolean that hope the answer will help someone else.

You can match those three groups separately, and make sure that they all present. Also, [^\w] seems a bit too broad, but if that's what you want you might want to replace it with \W.

Yes... by the time the regex compiler sees the pattern you've given it, it sees only a single backslash (since Java's lexer has turned the double backwhack into a single one). You need to replace "\\\\" with "\\\\", believe it or not! Java really needs a good raw string syntax.

To escape the backslash, simply use 2 of them, like this: \\

If you need to escape other things, this may be helpful..

malloc(0) may (optionally) return NULL, depending on the implementation. Do you realize why you may be calling malloc(0)? Or more precisely, do you see where you are reading and writing beyond the size of your arrays?

I just had to uninstall HAXM and install it again. Then it started working again. Hope this helps someone!

Edit:

Oh wow, this was a long time ago. I have been using genymotion for a few months now, and never had any issues like that.

Download and install Miniconda first from this link and later on download and install Anaconda. Then you will be able to see the navigator in your all programs list in the start menu. I hope this will help you. Let me know in case of any concerns.

And if you are using Command line on Windows, download a program ANSICON that enables console to accept color codes. ANSICON is available at https://github.com/adoxa/ansicon/releases

What I did in the end was:

• created a new branch jenkins-target, and got jenkins to track that
• merge from whichever branch or tag I want to build onto the jenkins-target
• once the build was working, tests passing etc, just simply create a tag from the jenkins-target branch

I'm not sure if this will work for everyone, my project was quite small, not too many tags and stuff, but it's dead easy to do, dont have to mess around with refspecs and parameters and stuff :-)

I had faced same problem because I downloaded TestNG plugin from Eclipse. Here what I did to get the Job done :

1. After adding TestNG to your project library create one folder in your Project names as lib ( name can be anything ) :

2. Go to "C:\Program Files\Eclipse\eclipse-java-mars-R-win32-x86_64\eclipse\plugins" location and copy com.beust.jcommander_1.72.0.jar and org.testng_6.14.2.r20180216145.jar file to created folder (lib).

Note : Files are testng.jar and jcommander.jar

3. Now Launch CMD, and navigate to your project directory and then type :
   Java -cp C:\Users\User123\TestNG\lib*;C:\Users\User123\TestNG\bin org.testng.TestNG testng.xml

That's it !
Let me know if you have any more concerns.

Off the top of my head, why don't you just Thread.Join(timeout) and remove the time it took to join from the total timeout?

// pseudo-c#:

TimeSpan timeout = timeoutPerThread * threads.Count();

foreach (Thread thread in threads)
{
    DateTime start = DateTime.Now;

    if (!thread.Join(timeout))
        throw new TimeoutException();

    timeout -= (DateTime.Now - start);
}

Edit: code is now less pseudo. don't understand why you would mod an answer -2 when the answer you modded +4 is exactly the same, only less detailed.

I think init_js should use declare instead of local!

function scan3() {
    declare -n outvar=$1    # -n makes it a nameref.
    local nl=$'\x0a'
    outvar="output${nl}${nl}"  # two total. quotes preserve newlines
}

Try to Use:

select * from sys.objects where type='tr' and name like '%_Insert%'

If you are using Hibernate 5+, then query will be modified as

Long count = session.createQuery("select count(1) from  Book")
                    .getSingleResult();

Or if you Need TypedQuery

Long count = session.createQuery("select count(1) from  Book",Long.class)
                        .getSingleResult();
