I also ran into the same problem with TestNG version 6.14.2

However, this was due to a foolish mistake on my end and there is no issue whatsoever with maven, testng or eclipse. What I was doing was -

1. Run project as "mvn clean"
2. Select "testng.xml" file and right click on it to run as TestNG suite
3. This was giving me the same error as reported in the original question
4. I soon realized that I have not compiled the project and the required class files have not been generated that the TestNG would utilize subsequently
5. The "target" folder will be generated only after the project is compiled (Run as "mvn build")
6. If your project is compiled, this issue should not be there.

When you generate a JAXB model from an XML Schema, global elements that correspond to named complex types will have that metadata captured as an @XmlElementDecl annotation on a create method in the ObjectFactory class. Since you are creating the JAXBContext on just the DocumentType class this metadata isn't being processed. If you generated your JAXB model from an XML Schema then you should create the JAXBContext on the generated package name or ObjectFactory class to ensure all the necessary metadata is processed.

Example solution:

JAXBContext jaxbContext = JAXBContext.newInstance(my.generatedschema.dir.ObjectFactory.class);
DocumentType documentType = ((JAXBElement<DocumentType>) jaxbContext.createUnmarshaller().unmarshal(inputStream)).getValue();

For me the problem was my file encoding...I used powershell to write the xml file and this was not UTF-8 ... It seems that spring requires UTF8 because as soon as I changed the encoding (using notepad++) it works again without any errors

Now i Use in my powershellscript the following line to output the xml file in UTF-8: [IO.File]::WriteAllLines($fname_dataloader_xml_config_file, $dataloader_configfile)

instead of using the redirection operator > to create my file

Note: I didn't put any xml parameters in my beans tag and it works

I had the same problem. I solved it by removing the line break from the xml file. I did

<operationBindings>
    <OperationBinding>
        <operationType>update</operationType>
        <operationId>makePdf</operationId>
        <serverObject>
            <className>com.myclass</className>
            <lookupStyle>new</lookupStyle>
        </serverObject>
        <serverMethod>makePdf</serverMethod>
    </OperationBinding>
</operationBindings>

instead of ...

<serverObject>
            <className>com.myclass
</className>
            <lookupStyle>new</lookupStyle>
</serverObject>

You can also use like this:

for(Iterator iterator = arrayList.iterator(); iterator.hasNext();) {
x = iterator.next();
//do some stuff
}

Its a good practice to cast and use the object. For example, if the 'arrayList' contains a list of 'Object1' objects. Then, we can re-write the code as:

for(Iterator iterator = arrayList.iterator(); iterator.hasNext();) {
x = (Object1) iterator.next();
//do some stuff
}

I had the same problem with some XML files, I solved reading the file with ANSI encoding (Windows-1252) and writing a file with UTF-8 encoding with a small script in Python. I tried use Notepad++ but I didn't have success:

import os
import sys

path = os.path.dirname(__file__)

file_name = 'my_input_file.xml'

if __name__ == "__main__":
    with open(os.path.join(path, './' + file_name), 'r', encoding='cp1252') as f1:
        lines = f1.read()
        f2 = open(os.path.join(path, './' + 'my_output_file.xml'), 'w', encoding='utf-8')
        f2.write(lines)
        f2.close()

Check the XML. It is not a valid xml.

Prolog is the first line with xml version info. It ok not to include it in your xml.

This error is thrown when the parser reads an invalid tag at the start of the document. Normally where the prolog resides.

e.g.

1. Root/><document>
2. Root<document>

I solved it

Adding this just as an addition to @jimt's excellent answer:

one common way to define it all at initialization time is using an anonymous struct:

var opts = []struct {
    shortnm      byte
    longnm, help string
    needArg      bool
}{
    {'a', "multiple", "Usage for a", false},
    {
        shortnm: 'b',
        longnm:  "b-option",
        needArg: false,
        help:    "Usage for b",
    },
}

This is commonly used for testing as well to define few test cases and loop through them.

If you have installed Jenkins via apt-get, you should also update Jenkins via apt-get to avoid future problems. Updating should work via "apt-get update" and then "apt-get upgrade".

I encountered the same error than adding

Here's an outline/boilerplate for describing the behavior of mapStateToProps:

(This is a vastly simplified implementation of what a Redux container does.)

class MyComponentContainer extends Component {
  mapStateToProps(state) {
    // this function is specific to this particular container
    return state.foo.bar;
  }

  render() {
    // This is how you get the current state from Redux,
    // and would be identical, no mater what mapStateToProps does
    const { state } = this.context.store.getState();

    const props = this.mapStateToProps(state);

    return <MyComponent {...this.props} {...props} />;
  }
}

and next

function buildReduxContainer(ChildComponentClass, mapStateToProps) {
  return class Container extends Component {
    render() {
      const { state } = this.context.store.getState();

      const props = mapStateToProps(state);

      return <ChildComponentClass {...this.props} {...props} />;
    }
  }
}

You can also use a service called Filepicker which will store your image to their servers and Filepicker which is now called Filestack, will provide you with a url to the image. You can than store the url to Firebase.

Do I really have to first convert it into an array of arrays of key-value pairs?

No, an iterator of key-value pair arrays is enough. You can use the following to avoid creating the intermediate array:

function* entries(obj) {
    for (let key in obj)
        yield [key, obj[key]];
}

const map = new Map(entries({foo: 'bar'}));
map.get('foo'); // 'bar'

jdbc:jtds:sqlserver://x.x.x.x/database replacing x.x.x.x with the IP or hostname of your SQL Server machine.

jdbc:jtds:sqlserver://MYPC/Blog;instance=SQLEXPRESS

or

jdbc:jtds:sqlserver://MYPC:1433/Blog;instance=SQLEXPRESS

If you are wanting to set the username and password in the connection string too instead of against a connection object separately:

jdbc:jtds:sqlserver://MYPC/Blog;instance=SQLEXPRESS;user=foo;password=bar

(Updated my incorrect information and add reference to the instance syntax)

You may try this sample, and always check your Connection String, you can use this example with or with out bindingsource you can load the data to datagridview.

private void Employee_Report_Load(object sender, EventArgs e)
{
        var table = new DataTable();

        var connection = "ConnectionString";

        using (var con = new SqlConnection { ConnectionString = connection })
        {
            using (var command = new SqlCommand { Connection = con })
            {

                if (con.State == ConnectionState.Open)
                {
                    con.Close();
                }

                con.Open();

                try
                {
                    command.CommandText = @"SELECT * FROM tblEmployee";
                    table.Load(command.ExecuteReader());

                    bindingSource1.DataSource = table;

                    dataGridView1.ReadOnly = true;
                    dataGridView1.DataSource = bindingSource1;

                }
                catch(SqlException ex)
                {
                    MessageBox.Show(ex.Message + " sql query error.");
                }

            }

        }

 }

SIMPLE..

First check with the closing tag of project. It should be placed after all the dependency tags are closed.This way I solved my error. --Sush happy coding :)

Or, if you want a more general approach - i.e. for nesting up to "levelN":

void Main()
{
    XElement rootElement = XElement.Load(@"c:\events\test.xml");

    Console.WriteLine(GetOutline(0, rootElement));  
}

private string GetOutline(int indentLevel, XElement element)
{
    StringBuilder result = new StringBuilder();

    if (element.Attribute("name") != null)
    {
        result = result.AppendLine(new string(' ', indentLevel * 2) + element.Attribute("name").Value);
    }

    foreach (XElement childElement in element.Elements())
    {
        result.Append(GetOutline(indentLevel + 1, childElement));
    }

    return result.ToString();
}

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

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

or

if 'List contents' in UserInput: 

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

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

As drew_w said, you can find a good example here.

JSFIDDLE

xmllint support formatting in-place:

for f in *.xml; do xmllint -o $f --format $f; done

As Daniel Veillard has written:

I think xmllint -o tst.xml --format tst.xml should be safe as the parser will fully load the input into a tree before opening the output to serialize it.

Indent level is controlled by XMLLINT_INDENT environment variable which is by default 2 spaces. Example how to change indent to 4 spaces:

XMLLINT_INDENT='    '  xmllint -o out.xml --format in.xml

You may have lack with --recover option when you XML documents are broken. Or try weak HTML parser with strict XML output:

xmllint --html --xmlout <in.xml >out.xml

--nsclean, --nonet, --nocdata, --noblanks etc may be useful. Read man page.

Move all of your state and your handleClick function from Header to your MainWrapper component.

Then pass values as props to all components that need to share this functionality.

class MainWrapper extends React.Component {
    constructor() {
        super();
        this.state = {
            sidbarPushCollapsed: false,
            profileCollapsed: false
        };
        this.handleClick = this.handleClick.bind(this);
    }
    handleClick() {
        this.setState({
            sidbarPushCollapsed: !this.state.sidbarPushCollapsed,
            profileCollapsed: !this.state.profileCollapsed

        });
    }
    render() {
        return (
           //...
           <Header 
               handleClick={this.handleClick} 
               sidbarPushCollapsed={this.state.sidbarPushCollapsed}
               profileCollapsed={this.state.profileCollapsed} />
        );

Then in your Header's render() method, you'd use this.props:

<button type="button" id="sidbarPush" onClick={this.props.handleClick} profile={this.props.profileCollapsed}>

You should include the repository where you want to deploy in the distribution management section of the pom.xml.

Example:

<project xmlns="http://maven.apache.org/POM/4.0.0"   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"   xsi:schemaLocation="http://maven.apache.org/POM/4.0.0

If your switch Install by USB on and you are getting "the device is temporarily restricted" error, then apply any of the default mobile themes. If any other developer theme is applied then it will not Allow you to switch Install by USB on. This works for me.

You can use the HTML tag in order to apply font size, font color in one line on JavaScript, as well as you can use .fontcolor() method to define color, .fontsize() method to define the font size, .bold() method to define bold, etc. These are called JavaScript Built-in Functions.

• Here is a list of some JavaScript built-in functions:

  .big()
  .small()
  .italics()
  .fixed()
  .strike()
  .sup()

• The below built-in functions require parameters:

  .fontsize() //e.g.: the size to be applied in number .fontsize(4)

  .fontcolor("") //e.g.: the color to be applied in string .fontcolor("red")

  .txt.link("") //e.g.: the url to be linkable as string .link("www.test.com")

  .toUpperCase() //e.g.: the converted to uppercase to be applied in string .toUpperCase()

• Remember the syntax is: string.functionName() e.g.:

  var txt = "Hello World!"; txt.bold();

• This also can be done in one line:

  var txt = "Hello World!".bold();

  The result will be: Hello World!

• You can use multiple built-in functions in one line, adding one next to the other. e.g.:

  "10/22/2018".fontcolor("red").fontsize(4).bold()

• The following is an example how I used it on my JavaScript code to change font (color, size, bold) using both HTML tags and JavaScript functions:

vForm.message = "<HTML><font size = 4 color = 'red'><b> Application Deadline was </b></font></HTML> " + "10/22/2018".fontcolor("red").fontsize(4).bold(); /* setting HTML font color, size, bold and combined them with JavaScript functions to change font color, size, bold in JavaScript code */

• Here is the result:

You can use form.get to get the specific control object and use setValue

this.form.get(<formControlName>).setValue(<newValue>);

I had the same issue when getting my software running on another machine. On my developer pc (Windows 7), I had Visual Studio 2015 installed, the target pc was a clean installation of Windows 10 (.Net installed). I also tested it on another clean Windows 7 pc including .Net Framework. However, on both target pc's I needed to install the Visual C++ Redistributable for Visual Studio 2015 package for x86 or x64 (depends on what your application is build for). That was already installed on my developer pc.

My application was using a C library, which has been compiled to a C++ application using /clr and /TP options in visual studio. Also the application was providing functions to C# by using dllexport method signatures. Not sure if the C# integration leaded to give me that error or if a C++ application would have given me the same.

Hope it helps anybody.

You are making an ajax request which is asynchronous therefore your console log of the list length occurs before the ajax request has completed.

The only way of achieving what you want is changing the ajax call to be synchronous. You can do this by using the .ajax and passing in asynch : false however this is not recommended as it locks the UI up until the call has returned, if it fails to return the user has to crash out of the browser.

If your DBMS doesn't support distinct with multiple columns like this:

select distinct(col1, col2) from table

Multi select in general can be executed safely as follows:

select distinct * from (select col1, col2 from table ) as x

As this can work on most of the DBMS and this is expected to be faster than group by solution as you are avoiding the grouping functionality.

Your DateFormat pattern does not match you input date String. You could use

new SimpleDateFormat("dd-MMM-yyyy")

See The Bash Manual under 3.4.2 Special Parameters:

? - Expands to the exit status of the most recently executed foreground pipeline.

It is a little hard to find because it is not listed as $? (the variable name is "just" ?). Also see the exit status section, of course ;-)

Happy coding.

The script package does exactly what you're looking for: https://atom.io/packages/script

The package's documentation also contains the key mappings, which you can easily customize.

Try jamspell - it works pretty well for automatic spelling correction:

import jamspell

corrector = jamspell.TSpellCorrector()
corrector.LoadLangModel('en.bin')

corrector.FixFragment('Some sentnec with error')
# u'Some sentence with error'

corrector.GetCandidates(['Some', 'sentnec', 'with', 'error'], 1)
# ('sentence', 'senate', 'scented', 'sentinel')

I personally prefer using the following code if it is for a single link. Otherwise it's probably best if you create a function with similar code.

onclick="this.target='_blank';"

I started using that to bypass the W3C's XHTML strict test.

You must remove the system.out.println message from below the return, like this:

public Item anyItem()
{
    randomGenerator = new Random();
    int index = randomGenerator.nextInt(catalogue.size());
    Item it = catalogue.get(index);
    System.out.println("Managers choice this week" + it + "our recommendation to you");
    return it;
}

the return statement basically says the function will now end. anything included beyond the return statement that is also in scope of it will result in the behavior you experienced

Margin auto on a grid-item.

Similarly to Flexbox, applying margin auto on a grid-item centers it on both axes:

.container {
  display: grid;
}
.element {
  margin: auto;
}

Matplotlib makes great publication-quality graphics, but is not very well optimized for speed. There are a variety of python plotting packages that are designed with speed in mind:

• http://vispy.org
• http://pyqtgraph.org/
• http://docs.enthought.com/chaco/
• http://pyqwt.sourceforge.net/
  [ edit: pyqwt is no longer maintained; the previous maintainer is recommending pyqtgraph ]

You can use {{ URL::previous() }} But it not perfect UX.

For example, when you press F5 button and click again to Back Button with {{ URL::previous() }} you will stay in.

A good way is using {{ route('page.edit', $item->id) }} it always true page you wanna to redirect.

This might help too:

$ java -cp classes test.LoginLDAP url=ldap://1.2.3.4:389 [email protected] password=mypwd

$ java -cp classes test.LoginLDAP url=ldaps://1.2.3.4:636 [email protected] password=mypwd

Test application supports temporary self-signed test certificates for ldaps:// protocol, this DummySSLFactory accepts any server cert so man-in-the-middle is possible. Real life installation should import server certificate to a local JKS keystore file and not using dummy factory.

Application uses enduser's username+password for initial context and ldap queries, it works for WinAD but don't know if can be used for all ldap server implementations. You could create context with internal username+pwd then run queries to see if given enduser is found.

In MySQL there is a group_concat function that will return what you're asking for.

SELECT TableA.ID, TableA.Name, group_concat(TableB.SomeColumn) 
as SomColumnGroup FROM TableA LEFT JOIN TableB ON 
TableB.TableA_ID = TableA.ID

Use this

x = Object.create(x1);

x and x1 will be two different object,change in x will not change x1

If $_SERVER['HTTP_REFERER'] variable doesn't seems to work, then you can either use Google Analytics or AddThis Analytics.

It is possible on your restart some shards were not recovered, causing the cluster to stay red.
If you hit:
http://<yourhost>:9200/_cluster/health/?level=shards you can look for red shards.

I have had issues on restart where shards end up in a non recoverable state. My solution was to simply delete that index completely. That is not an ideal solution for everyone.

It is also nice to visualize issues like this with a plugin like:
Elasticsearch Head

Perfect, try it:

SELECT ROUTINE_DEFINITION FROM INFORMATION_SCHEMA.ROUTINES
    WHERE ROUTINE_SCHEMA = 'yourdb' AND ROUTINE_TYPE = 'PROCEDURE' AND ROUTINE_NAME = "procedurename";

This question has been already answered in Unicode characters in Windows command line - how?

You missed one step -> you need to use Lucida console fonts in addition to executing chcp 65001 from cmd console.

Jython DOES carry out certificate verification by default, so using standard library modules, e.g. httplib.HTTPSConnection, etc, with jython will verify certificates and give exceptions for failures, i.e. mismatched identities, expired certs, etc.

In fact, you have to do some extra work to get jython to behave like cpython, i.e. to get jython to NOT verify certs.

I have written a blog post on how to disable certificate checking on jython, because it can be useful in testing phases, etc.

Just to keep it simple I have used this approach. Simple as in to explain how really ipv4 address is evaluated. Checking whether its a binary number is although not required. Hope you like this.

You can truncate all information after the month using date_trunc(text, timestamp):

select date_trunc('month',created_at)::date as date 
from orders 
order by date DESC;

created_at = '2019-12-16 18:28:13'

Output 1:

date_trunc('day',created_at)
// 2019-12-16 00:00:00

Output 2:

date_trunc('day',created_at)::date 
// 2019-12-16

Output 3:

date_trunc('month',created_at)::date 
// 2019-12-01

Output 4:

date_trunc('year',created_at)::date 
// 2019-01-01

First, let's make some test data:

create table client (client_id integer not null primary key auto_increment,
                     name varchar(64));
create table portfolio (portfolio_id integer not null primary key auto_increment,
                        client_id integer references client.id,
                        cash decimal(10,2),
                        stocks decimal(10,2));
insert into client (name) values ('John Doe'), ('Jane Doe');
insert into portfolio (client_id, cash, stocks) values (1, 11.11, 22.22),
                                                       (1, 10.11, 23.22),
                                                       (2, 30.30, 40.40),
                                                       (2, 40.40, 50.50);

If you didn't need the portfolio ID, it would be easy:

select client_id, name, max(cash + stocks)
from client join portfolio using (client_id)
group by client_id

+-----------+----------+--------------------+
| client_id | name     | max(cash + stocks) |
+-----------+----------+--------------------+
|         1 | John Doe |              33.33 | 
|         2 | Jane Doe |              90.90 | 
+-----------+----------+--------------------+

Since you need the portfolio ID, things get more complicated. Let's do it in steps. First, we'll write a subquery that returns the maximal portfolio value for each client:

select client_id, max(cash + stocks) as maxtotal
from portfolio
group by client_id

+-----------+----------+
| client_id | maxtotal |
+-----------+----------+
|         1 |    33.33 | 
|         2 |    90.90 | 
+-----------+----------+

Then we'll query the portfolio table, but use a join to the previous subquery in order to keep only those portfolios the total value of which is the maximal for the client:

 select portfolio_id, cash + stocks from portfolio 
 join (select client_id, max(cash + stocks) as maxtotal 
       from portfolio
       group by client_id) as maxima
 using (client_id)
 where cash + stocks = maxtotal

+--------------+---------------+
| portfolio_id | cash + stocks |
+--------------+---------------+
|            5 |         33.33 | 
|            6 |         33.33 | 
|            8 |         90.90 | 
+--------------+---------------+

Finally, we can join to the client table (as you did) in order to include the name of each client:

select client_id, name, portfolio_id, cash + stocks
from client
join portfolio using (client_id)
join (select client_id, max(cash + stocks) as maxtotal
      from portfolio 
      group by client_id) as maxima
using (client_id)
where cash + stocks = maxtotal

+-----------+----------+--------------+---------------+
| client_id | name     | portfolio_id | cash + stocks |
+-----------+----------+--------------+---------------+
|         1 | John Doe |            5 |         33.33 | 
|         1 | John Doe |            6 |         33.33 | 
|         2 | Jane Doe |            8 |         90.90 | 
+-----------+----------+--------------+---------------+

Note that this returns two rows for John Doe because he has two portfolios with the exact same total value. To avoid this and pick an arbitrary top portfolio, tag on a GROUP BY clause:

select client_id, name, portfolio_id, cash + stocks
from client
join portfolio using (client_id)
join (select client_id, max(cash + stocks) as maxtotal
      from portfolio 
      group by client_id) as maxima
using (client_id)
where cash + stocks = maxtotal
group by client_id, cash + stocks

+-----------+----------+--------------+---------------+
| client_id | name     | portfolio_id | cash + stocks |
+-----------+----------+--------------+---------------+
|         1 | John Doe |            5 |         33.33 | 
|         2 | Jane Doe |            8 |         90.90 | 
+-----------+----------+--------------+---------------+

Try also to use the cksum command:

chk1=`cksum <file1> | awk -F" " '{print $1}'`
chk2=`cksum <file2> | awk -F" " '{print $1}'`

if [ $chk1 -eq $chk2 ]
then
  echo "File is identical"
else
  echo "File is not identical"
fi

The cksum command will output the byte count of a file. See 'man cksum'.

The git blame command is used to know who/which commit is responsible for the latest changes made to a file. The author/commit of each line can also been seen.

git blame filename (commits responsible for changes for all lines in code)

git blame filename -L 0,10 (commits responsible for changes from line "0" to line "10")

There are many other options for blame, but generally these could help.

In foreach loop instead of carBootSaleList use carBootSaleList.data.

You probably do not need answer anymore, but it could help someone.

Push and Pop make sense in terms of the metaphor of a stack of plates or trays in a cafeteria or buffet, specifically the ones in type of holder that has a spring underneath so the top plate is (more or less... in theory) in the same place no matter how many plates are under it.

If you remove a tray, the weight on the spring is a little less and the stack "pops" up a little, if you put the plate back, it "push"es the stack down. So if you think about the list as a stack and the last element as being on top, then you shouldn't have much confusion.

I’m not a git expert and just arrived on this forum to understand it! Thus maybe my explanation is not perfect, sorry for that. I found all the other answer helpful and I will just try to give another perspective. I will modify a bit the question since I guess that it was maybe the intent of the author: “I’m new to git. Before using git, I was renaming my files like this: main.c, main_1.c, main_2.c when i was performing majors changes in order to be able to go back in case of trouble. Thus, if I decided to come back to main_1.c, it was easy and I also keep main_2.c and main_3.c since I could also need them later. How can I easily do the same thing using git?” For my answer, I mainly use the “regret number three” of the great answer of Matt above because I also think that the initial question is about “what do I do if I have regret when using git?”. At the beginning, the situation is like that:

A-B-C-D (master)

1. The first main point is to create a new branch: git branch mynewbranch. Then one get:

A-B-C-D (master and mynewbranch)

2. Let’s suppose now that one want to come back to A (3 commits before). The second main point is to use the command git reset --hard even if one can read on the net that it is dangerous. Yes, it’s dangerous but only for uncommitted changes. Thus, the way to do is:

Git reset --hard thenumberofthecommitA

or

Git reset --hard master~3

Then one obtains: A (master) – B – C – D (mynewbranch)

Then, it’s possible to continue working and commit from A (master) but still can get an easy access to the other versions by checking out on the other branch: git checkout mynewbranch. Now, let’s imagine that one forgot to create a new branch before the command git reset --hard. Is the commit B, C, D are lost? No, but there are not stored in any branches. To find them again, one may use the command : git reflog that is consider as “a safety command”( “in case of trouble, keep calm and use git reflog”). This command will list all commits even those that not belong to any branches. Thus, it’s a convenient way to find the commit B, C or D.

First - stop Jenkins service:

sudo service jenkins stop

Next - delete:

sudo apt-get remove --purge jenkins

If you used separate server for Jenkins, some GCP or AWS - just delete this server. Here is a video how to uninstall Jenkins from GCP Compute Engine https://youtu.be/D2HUFAc_Trw

You can do this in two ways:

1. ElementMatch - $elemMatch (as explained in above answers)

   db.users.find({ awards: { $elemMatch: {award:'Turing Award', year:1977} } })

2. Use $and with find

   db.getCollection('users').find({"$and":[{"awards.award":"Turing Award"},{"awards.year":1977}]})

Another important thing I noticed is that when running the application it ignores capitals in file/folders in the resources folder where it doesn't ignore it while running as a jar. Therefore, in case your file is in the resources folder under Testfolder/messages.txt

@Autowired
ApplicationContext appContext;

// this will work when running the application, but will fail when running as jar
appContext.getResource("classpath:testfolder/message.txt");

Therefore, don't use capitals in your resources or also add those capitals in your constructor of ClassPathResource:

appContext.getResource("classpath:Testfolder/message.txt");

in KotlinDSL you can use like this :

flavorDimensions ("PlaceApp")
productFlavors {
    create("tapsi") {
        setDimension("PlaceApp")
        buildConfigField("String", "API_BASE_URL", "https://xxx/x/x/")
    }

}

You need to set the g flag to replace globally:

date.replace(new RegExp("/", "g"), '')
// or
date.replace(/\//g, '')

Otherwise only the first occurrence will be replaced.

I believe that you're looking for numpy.split or possibly numpy.array_split if the number of sections doesn't need to divide the size of the array properly.

You can use the Array.prototype.filter method:

         el.num_of_beds >=2 &&
         el.num_of_baths >= 2.5;

This method is part of the new ECMAScript 5th Edition standard, and can be found on almost all modern browsers.

For IE, you can include the following method for compatibility:

if (!Array.prototype.filter) {
  Array.prototype.filter = function(fun /*, thisp*/) {
    var len = this.length >>> 0;
    if (typeof fun != "function")
      throw new TypeError();

    var res = [];
    var thisp = arguments[1];
    for (var i = 0; i < len; i++) {
      if (i in this) {
        var val = this[i];
        if (fun.call(thisp, val, i, this))
          res.push(val);
      }
    }
    return res;
  };
}

I ran into this issue with Python 3.6 and Python 3.7. The top answer (running pip install --upgrade pip enum34) did not solve the problem.

I don't know why, but the reason why this error happen is because enum.py was missing from .venv/myvenv/lib/python3.7/.

But the file was in /usr/lib/python3.7/.

Following this answer, I just created the symbolic link by myself :

ln -s /usr/lib/python3.7/enum.py .venv/myvenv/lib/python3.7/enum.py

Most of the answers in this thread are using plain vim commands which is of course fine but I thought I would provide an extensive answer using a combination of plugins and functions that I find particularly useful (at least some of these tips came from Gary Bernhardt's file navigation tips):

1. To toggle between the last two file just press <leader> twice. I recommend assigning <leader> to the spacebar:

   nnoremap <leader><leader> <c-^>
   

2. For quickly moving around a project the answer is a fuzzy matching solution such as CtrlP. I bind it to <leader>a for quick access.

3. In the case I want to see a visual representation of the currently open buffers I use the BufExplorer plugin. Simple but effective.

4. If I want to browse around the file system I would use the command line or an external utility (Quicklsilver, Afred etc.) but to look at the current project structure NERD Tree is a classic. Do not use this though in the place of 2 as your main file finding method. It will really slow you down. I use the binding <leader>ff.

These should be enough for finding and opening files. From there of course use horizontal and vertical splits. Concerning splits I find these functions particularly useful:

1. Open new splits in smaller areas when there is not enough room and expand them on navigation. Refer here for comments on what these do exactly:

   set winwidth=84
   set winheight=5
   set winminheight=5
   set winheight=999
   
   nnoremap <C-w>v :111vs<CR>
   nnoremap <C-w>s :rightbelow split<CR>
   set splitright
   

2. Move from split to split easily:

   nnoremap <C-J> <C-W><C-J>
   nnoremap <C-K> <C-W><C-K>
   nnoremap <C-L> <C-W><C-L>
   nnoremap <C-H> <C-W><C-H>
   

How do you plan to save last saved position with RecyclerView.State?

You can always rely on ol' good save state. Extend RecyclerView and override onSaveInstanceState() and onRestoreInstanceState():

    @Override
    protected Parcelable onSaveInstanceState() {
        Parcelable superState = super.onSaveInstanceState();
        LayoutManager layoutManager = getLayoutManager();
        if(layoutManager != null && layoutManager instanceof LinearLayoutManager){
            mScrollPosition = ((LinearLayoutManager) layoutManager).findFirstVisibleItemPosition();
        }
        SavedState newState = new SavedState(superState);
        newState.mScrollPosition = mScrollPosition;
        return newState;
    }

    @Override
    protected void onRestoreInstanceState(Parcelable state) {
        super.onRestoreInstanceState(state);
        if(state != null && state instanceof SavedState){
            mScrollPosition = ((SavedState) state).mScrollPosition;
            LayoutManager layoutManager = getLayoutManager();
            if(layoutManager != null){
              int count = layoutManager.getItemCount();
              if(mScrollPosition != RecyclerView.NO_POSITION && mScrollPosition < count){
                  layoutManager.scrollToPosition(mScrollPosition);
              }
            }
        }
    }

    static class SavedState extends android.view.View.BaseSavedState {
        public int mScrollPosition;
        SavedState(Parcel in) {
            super(in);
            mScrollPosition = in.readInt();
        }
        SavedState(Parcelable superState) {
            super(superState);
        }

        @Override
        public void writeToParcel(Parcel dest, int flags) {
            super.writeToParcel(dest, flags);
            dest.writeInt(mScrollPosition);
        }
        public static final Parcelable.Creator<SavedState> CREATOR
                = new Parcelable.Creator<SavedState>() {
            @Override
            public SavedState createFromParcel(Parcel in) {
                return new SavedState(in);
            }

            @Override
            public SavedState[] newArray(int size) {
                return new SavedState[size];
            }
        };
    }

I had the same problem. Spring boot knows where static html files are located.

1. Add index.html into resources/static folder
2. Then delete full controller method for root path like @RequestMapping("/") etc
3. Run app and check http://localhost:8080 (Should work)

I have also faced the same issue, The solution for it is : the file for which you are getting the error is probably a duplicated file of the actual file with another version. So just the removal of a particular file on which errors are thrown can resolve the issue.

  function truncateString(str, length) {
     return str.length > length ? str.substring(0, length - 3) + '...' : str
  }

In simple words: You do abstraction when deciding what to implement. You do encapsulation when hiding something that you have implemented.

Brando ZWZ provides some great answers to handling this situation.

Re: Same navbar on multiple pages Aug 21, 2018 10:13 AM|LINK

As far as I know, there are multiple solution.

For example:

The Entire code for navigation bar is in nav.html file (without any html or body tag, only the code for navigation bar).

Then we could directly load it from the jquery without writing a lot of codes.

Like this:

    <!--Navigation bar-->
    <div id="nav-placeholder">

    </div>

    <script>
    $(function(){
      $("#nav-placeholder").load("nav.html");
    });
    </script>
    <!--end of Navigation bar-->

Solution2:

You could use JavaScript code to generate the whole nav bar.

Like this:

Javascript code:

$(function () {
    var bar = '';
    bar += '<nav class="navbar navbar-default" role="navigation">';
    bar += '<div class="container-fluid">';
    bar += '<div>';
    bar += '<ul class="nav navbar-nav">';
    bar += '<li id="home"><a href="home.html">Home</a></li>';
    bar += '<li id="index"><a href="index.html">Index</a></li>';
    bar += '<li id="about"><a href="about.html">About</a></li>';
    bar += '</ul>';
    bar += '</div>';
    bar += '</div>';
    bar += '</nav>';

    $("#main-bar").html(bar);

    var id = getValueByName("id");
    $("#" + id).addClass("active");
});

function getValueByName(name) {
    var url = document.getElementById('nav-bar').getAttribute('src');
    var param = new Array();
    if (url.indexOf("?") != -1) {
        var source = url.split("?")[1];
        items = source.split("&");
        for (var i = 0; i < items.length; i++) {
            var item = items[i];
            var parameters = item.split("=");
            if (parameters[0] == "id") {
                return parameters[1];
            }
        }
    }
}

See the Java EE 7 Json specification. This is the right way:

String json = Json.createObjectBuilder()
            .add("key1", "value1")
            .add("key2", "value2")
            .build()
            .toString();

Here is an example using openssl_encrypt

//Encryption:
$textToEncrypt = "My Text to Encrypt";
$encryptionMethod = "AES-256-CBC";
$secretHash = "encryptionhash";
$iv = mcrypt_create_iv(16, MCRYPT_RAND);
$encryptedText = openssl_encrypt($textToEncrypt,$encryptionMethod,$secretHash, 0, $iv);

//Decryption:
$decryptedText = openssl_decrypt($encryptedText, $encryptionMethod, $secretHash, 0, $iv);
print "My Decrypted Text: ". $decryptedText;

The ErrorDocument directive, when supplied a local URL path, expects the path to be fully qualified from the DocumentRoot. In your case, this means that the actual path to the ErrorDocument is

ErrorDocument 404 /hellothere/error/404page.html

try this:

declare @i tinyint = 0,
    @count tinyint,
    @id int,
    @name varchar(max)

select @count = count(*) from table
while (@i < @count)
begin
    select @id = id, @name = name from table
    order by nr asc offset @i rows fetch next 1 rows only

    exec stored_proc @varName = @id, @otherVarName = 'test', @varForName = @name

    set @i = @i + 1
end

How about storing it in a variable?

#extraargs=-F
ls -l $extraargs -a /etc

If you assign it to a class it should work:

<script>
  function changeClass(){
    document.getElementById('myButton').className = 'formatForButton';
  }
</script>

<style>
  .formatForButton {
    background-color:pink;
   }
</style>

<body>
  <input id='myButton' type=button class=none value='Change Color to pink' onclick='changeClass()'>
</body>

Look into JAXB.

Try:

mmatrix = np.zeros((nrows, ncols))

Since the shape parameter has to be an int or sequence of ints

http://docs.scipy.org/doc/numpy/reference/generated/numpy.zeros.html

Otherwise you are passing ncols to np.zeros as the dtype.

#pragma pack instructs the compiler to pack structure members with particular alignment. Most compilers, when you declare a struct, will insert padding between members to ensure that they are aligned to appropriate addresses in memory (usually a multiple of the type's size). This avoids the performance penalty (or outright error) on some architectures associated with accessing variables that are not aligned properly. For example, given 4-byte integers and the following struct:

struct Test
{
   char AA;
   int BB;
   char CC;
};

The compiler could choose to lay the struct out in memory like this:

|   1   |   2   |   3   |   4   |  

| AA(1) | pad.................. |
| BB(1) | BB(2) | BB(3) | BB(4) | 
| CC(1) | pad.................. |

and sizeof(Test) would be 4 × 3 = 12, even though it only contains 6 bytes of data. The most common use case for the #pragma (to my knowledge) is when working with hardware devices where you need to ensure that the compiler does not insert padding into the data and each member follows the previous one. With #pragma pack(1), the struct above would be laid out like this:

|   1   |

| AA(1) |
| BB(1) |
| BB(2) |
| BB(3) |
| BB(4) |
| CC(1) |

And sizeof(Test) would be 1 × 6 = 6.

With #pragma pack(2), the struct above would be laid out like this:

|   1   |   2   | 

| AA(1) | pad.. |
| BB(1) | BB(2) |
| BB(3) | BB(4) |
| CC(1) | pad.. |

And sizeof(Test) would be 2 × 4 = 8.

Order of variables in struct is also important. With variables ordered like following:

struct Test
{
   char AA;
   char CC;
   int BB;
};

and with #pragma pack(2), the struct would be laid out like this:

|   1   |   2   | 

| AA(1) | CC(1) |
| BB(1) | BB(2) |
| BB(3) | BB(4) |

and sizeOf(Test) would be 3 × 2 = 6.

The easiest way to tweak this in my opinion (imho) is to edit the .git/config file in your repository. Look for the entry you messed up and just tweak the URL.

On my machine in a repo I regularly use it looks like this:

KidA% cat .git/config 
[core]
    repositoryformatversion = 0
    filemode = true
    bare = false
    logallrefupdates = true
    ignorecase = true
    autocflg = true
[remote "origin"]
    url = ssh://localhost:8888/opt/local/var/git/project.git
    #url = ssh://xxx.xxx.xxx.xxx:80/opt/local/var/git/project.git
    fetch = +refs/heads/*:refs/remotes/origin/*

The line you see commented out is an alternative address for the repository that I sometimes switch to simply by changing which line is commented out.

This is the file that is getting manipulated under-the-hood when you run something like git remote rm or git remote add but in this case since its only a typo you made it might make sense to correct it this way.

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

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

EDIT

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

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

You don't mention the API version, but since API 11 there's the method WebViewClient.shouldInterceptRequest

Maybe this could help?

I think your regex is almost complete - here's what I would do:

lines2 = lines.gsub(/[\r\n]+/m, "\n")

In the above, I've put \r and \n into a class (that way it doesn't matter in which order they might appear) and added the "+" qualifier (so that "\r\n\r\n\r\n" would also match once, and the whole thing replaced with "\n")

This might help you

In most cases, the system does not relaunch apps after they are force quit by the user. One exception is location apps, which in iOS 8 and later are relaunched after being force quit by the user. In other cases, though, the user must launch the app explicitly or reboot the device before the app can be launched automatically into the background by the system. When password protection is enabled on the device, the system does not launch an app in the background before the user first unlocks the device.

Here's my setup:

1. Install both Python 2.7 and 3.4 with the windows installers.
2. Go to C:\Python34 (the default install path) and change python.exe to python3.exe
3. Edit your environment variables to include C:\Python27\;C:\Python27\Scripts\;C:\Python34\;C:\Python34\Scripts\;

Now in command line you can use python for 2.7 and python3 for 3.4.

Even though CMD is written down in the Dockerfile, it really is runtime information. Just like EXPOSE, but contrary to e.g. RUN and ADD. By this, I mean that you can override it later, in an extending Dockerfile, or simple in your run command, which is what you are experiencing. At all times, there can be only one CMD.

If you want to run multiple services, I indeed would use supervisor. You can make a supervisor configuration file for each service, ADD these in a directory, and run the supervisor with supervisord -c /etc/supervisor to point to a supervisor configuration file which loads all your services and looks like

[supervisord]
nodaemon=true

[include]
files = /etc/supervisor/conf.d/*.conf

If you would like more details, I wrote a blog on this subject here: http://blog.trifork.com/2014/03/11/using-supervisor-with-docker-to-manage-processes-supporting-image-inheritance/

Try the article background-size. If you use all of the following, it will work in most browsers except Internet Explorer.

.foo {

    -o-background-size: 100% 100%;
    -webkit-background-size: 100% 100%; 
    background-size: 100% 100%;
} 

You could always treat the list like a stack just popping the elements off the top of the stack from the back end of the list. That way you take advantage of first in last out characteristics of a stack. Of course you are consuming the 1st array. I do like this method in that it's pretty intuitive in that you see one list being consumed from the back end while the other is being built from the front end.

>>> l = [1,2,3,4,5,6]; nl=[]
>>> while l:
        nl.append(l.pop())  
>>> print nl
[6, 5, 4, 3, 2, 1]

You must group both columns, group and sub-group, then use the aggregate function COUNT().

  group, subgroup, COUNT(*)

Use WITH ORDINALITY for set-returning functions:

When a function in the FROM clause is suffixed by WITH ORDINALITY, a bigint column is appended to the output which starts from 1 and increments by 1 for each row of the function's output. This is most useful in the case of set returning functions such as unnest().

In combination with the LATERAL feature in pg 9.3+, and according to this thread on pgsql-hackers, the above query can now be written as:

SELECT t.id, a.elem, a.nr
FROM   tbl AS t
LEFT   JOIN LATERAL unnest(string_to_array(t.elements, ','))
                    WITH ORDINALITY AS a(elem, nr) ON TRUE;

LEFT JOIN ... ON TRUE preserves all rows in the left table, even if the table expression to the right returns no rows. If that's of no concern you can use this otherwise equivalent, less verbose form with an implicit CROSS JOIN LATERAL:

SELECT t.id, a.elem, a.nr
FROM   tbl t, unnest(string_to_array(t.elements, ',')) WITH ORDINALITY a(elem, nr);

Or simpler if based off an actual array (arr being an array column):

SELECT t.id, a.elem, a.nr
FROM   tbl t, unnest(t.arr) WITH ORDINALITY a(elem, nr);

Or even, with minimal syntax:

SELECT id, a, ordinality
FROM   tbl, unnest(arr) WITH ORDINALITY a;

a is automatically table and column alias. The default name of the added ordinality column is ordinality. But it's better (safer, cleaner) to add explicit column aliases and table-qualify columns.

Postgres 8.4 - 9.3

With row_number() OVER (PARTITION BY id ORDER BY elem) you get numbers according to the sort order, not the ordinal number of the original ordinal position in the string.

You can simply omit ORDER BY:

SELECT *, row_number() OVER (PARTITION by id) AS nr
FROM  (SELECT id, regexp_split_to_table(elements, ',') AS elem FROM tbl) t;

While this normally works and I have never seen it fail in simple queries, PostgreSQL asserts nothing concerning the order of rows without ORDER BY. It happens to work due to an implementation detail.

To guarantee ordinal numbers of elements in the blank-separated string:

SELECT id, arr[nr] AS elem, nr
FROM  (
   SELECT *, generate_subscripts(arr, 1) AS nr
   FROM  (SELECT id, string_to_array(elements, ' ') AS arr FROM tbl) t
   ) sub;

Or simpler if based off an actual array:

SELECT id, arr[nr] AS elem, nr
FROM  (SELECT *, generate_subscripts(arr, 1) AS nr FROM tbl) t;

Related answer on dba.SE:

• How to preserve the original order of elements in an unnested array?

Postgres 8.1 - 8.4

None of these features are available, yet: RETURNS TABLE, generate_subscripts(), unnest(), array_length(). But this works:

CREATE FUNCTION f_unnest_ord(anyarray, OUT val anyelement, OUT ordinality integer)
  RETURNS SETOF record
  LANGUAGE sql IMMUTABLE AS
'SELECT $1[i], i - array_lower($1,1) + 1
 FROM   generate_series(array_lower($1,1), array_upper($1,1)) i';

Note in particular, that the array index can differ from ordinal positions of elements. Consider this demo with an extended function:

CREATE FUNCTION f_unnest_ord_idx(anyarray, OUT val anyelement, OUT ordinality int, OUT idx int)
  RETURNS SETOF record
  LANGUAGE sql IMMUTABLE AS

Removing files using rm is not a problem per se, but if you then want to commit that the file was removed, you will have to do a git rm anyway, so you might as well do it that way right off the bat.

Also, depending on your shell, doing git rm after having deleted the file, you will not get tab-completion so you'll have to spell out the path yourself, whereas if you git rm while the file still exists, tab completion will work as normal.

you could register an interval on the page using setInterval, ie:

setInterval(function(){ 
    //code goes here that will be run every 5 seconds.    
}, 5000);

I know its late to post, but I use the site for my own reference and so I wanted to put an answer here for myself to reference in the future too. I hope you (and others) find it helpful.

Lets pretend a bunch of super Einstein experts designed our database. Our super perfect database has 3 tables, and the following relationships defined between them:

TblA 1:M TblB
TblB 1:M TblC

Notice there is no relationship between TblA and TblC

In most scenarios such a simple database is easy to navigate but in commercial databases it is usually impossible to be able to tell at the design stage all the possible uses and combination of uses for data, tables, and even whole databases, especially as systems get built upon and other systems get integrated or switched around or out. This simple fact has spawned a whole industry built on top of databases called Business Intelligence. But I digress...

In the above case, the structure is so simple to understand that its easy to see you can join from TblA, through to B, and through to C and vice versa to get at what you need. It also very vaguely highlights some of the problems with doing it. Now expand this simple chain to 10 or 20 or 50 relationships long. Now all of a sudden you start to envision a need for exactly your scenario. In simple terms, a join from A to C or vice versa or A to F or B to Z or whatever as our system grows.

There are many ways this can indeed be done. The one mentioned above being the most popular, that is driving through all the links. The major problem is that its very slow. And gets progressively slower the more tables you add to the chain, the more those tables grow, and the further you want to go through it.

Solution 1: Look for a common link. It must be there if you taught of a reason to join A to C. If it is not obvious, create a relationship and then join on it. i.e. To join A through B through C there must be some commonality or your join would either produce zero results or a massive number or results (Cartesian product). If you know this commonality, simply add the needed columns to A and C and link them directly.

The rule for relationships is that they simply must have a reason to exist. Nothing more. If you can find a good reason to link from A to C then do it. But you must ensure your reason is not redundant (i.e. its already handled in some other way).

Now a word of warning. There are some pitfalls. But I don't do a good job of explaining them so I will refer you to my source instead of talking about it here. But remember, this is getting into some heavy stuff, so this video about fan and chasm traps is really only a starting point. You can join without relationships. But I advise watching this video first as this goes beyond what most people learn in college and well into the territory of the BI and SAP guys. These guys, while they can program, their day job is to specialise in exactly this kind of thing. How to get massive amounts of data to talk to each other and make sense.

This video is one of the better videos I have come across on the subject. And it's worth looking over some of his other videos. I learned a lot from him.

So if i understood well, i would say that <pluginManagement> just like <dependencyManagement> are both used to share only the configuration between a parent and it's sub-modules.

For that we define the dependencie's and plugin's common configurations in the parent project and then we only have to declare the dependency/plugin in the sub-modules to use it, without having to define a configuration for it (i.e version or execution, goals, etc). Though this does not prevent us from overriding the configuration in the submodule.

In contrast <dependencies> and <plugins> are inherited along with their configurations and should not be redeclared in the sub-modules, otherwise a conflict would occur.

is that right ?

The correct way of referring to a method parameter is like this:

Another possible solution if you own the website is to use inline installation.

if (chrome.app.isInstalled) {
  // extension is installed.
}

I know this an old question but this way was introduced in Chrome 15 and so I thought Id list it for anyone only now looking for an answer.

I have faced the same issue and also not using virtual environment. easy_install is working for me.

Don't worry about performance until you have got a simple and sound design that agrees with the subject matter that the data describes and fits well with the intended use of the data. Then, if performance problems emerge, you can deal with them by tweaking the system.

In this case, it's almost always better to go with a string as a natural primary key, provide you can trust it. Don't worry if it's a string, as long as the string is reasonably short, say about 25 characters max. You won't pay a big price in terms of performance.

Do the data entry people or automatic data sources always provide a value for the supposed natural key, or is sometimes omitted? Is it occasionally wrong in the input data? If so, how are errors detected and corrected?

Are the programmers and interactive users who specify queries able to use the natural key to get what they want?

If you can't trust the natural key, invent a surrogate. If you invent a surrogate, you might as well invent an integer. Then you have to worry about whther to conceal the surrogate from the user community. Some developers who didn't conceal the surrogate key came to regret it.

Bootstrap has a wide range of responsive margin and padding utility classes. They work for all breakpoints:

xs (<=576px), sm (>=576px), md (>=768px), lg (>=992px) or xl (>=1200px))

The classes are used in the format:

{property}{sides}-{size} for xs & {property}{sides}-{breakpoint}-{size} for sm, md, lg, and xl.

m - sets margin

p - sets padding

t - sets margin-top or padding-top

b - sets margin-bottom or padding-bottom

l - sets margin-left or padding-left

r - sets margin-right or padding-right

x - sets both padding-left and padding-right or margin-left and margin-right

y - sets both padding-top and padding-bottom or margin-top and margin-bottom

blank - sets a margin or padding on all 4 sides of the element

0 - sets margin or padding to 0

1 - sets margin or padding to .25rem (4px if font-size is 16px)

2 - sets margin or padding to .5rem (8px if font-size is 16px)

3 - sets margin or padding to 1rem (16px if font-size is 16px)

4 - sets margin or padding to 1.5rem (24px if font-size is 16px)

5 - sets margin or padding to 3rem (48px if font-size is 16px)

auto - sets margin to auto

Funnily enough, adjusting the padding seems to do it.

My understanding is that if you use a View object (as supposed to eg. android:windowBackground) Android will automatically scale your image to the correct size. The problem is that too much scaling can result in artifacts (both during up and down scaling) and blurring. Due to various resolutions and aspects ratios on the market, it's impossible to create "perfect" fits for every screen, but you can do your best to make sure only a little bit of scaling has to be done, and thus mitigate the unwanted side effects. So what I would do is:

• Keep to the 3:4:6:8:12:16 scaling ratio between the six generalized densities (ldpi, mdpi, hdpi, etc).
• You should not include xxxhdpi elements for your UI elements, this resolution is meant for upscaling launcher icons only (so mipmap folder only) ... You should not use the xxxhdpi qualifier for UI elements other than the launcher icon. ... although eg. on the Samsung edge 7 calling getDisplayMetrics().density returns 4 (xxxhdpi), so perhaps this info is outdated.

• Then look at the new phone models on the market, and find the representative ones. Assumming the new google pixel is a good representation of an android phone: It has a 1080 x 1920 resolution at 441 dpi, and a screen size of 4.4 x 2.5 inches. Then from the the android developer docs:

  • ldpi (low) ~120dpi
  • mdpi (medium) ~160dpi
  • hdpi (high) ~240dpi
  • xhdpi (extra-high) ~320dpi
  • xxhdpi (extra-extra-high) ~480dpi
  • xxxhdpi (extra-extra-extra-high) ~640dpi

  This corresponds to an xxhdpi screen. From here I could scale these 1080 x 1920 down by the (3:4:6:8:12) ratios above.

• I could also acknowledge that downsampling is generally an easy way to scale and thus I might want slightly oversized bitmaps bundled in my apk (Note: higher memory consumption). Once more assuming that the width and height of the pixel screen is represetative, I would scale up the 1080x1920 by a factor of 480/441, leaving my maximum resolution background image at approx. 1200x2100, which should then be scaled by the 3:4:6:8:12.
• Remember, you only need to provide density-specific drawables for bitmap files (.png, .jpg, or .gif) and Nine-Patch files (.9.png). If you use XML files to define drawable resources (eg. shapes), just put one copy in the default drawable directory.
• If you ever have to accomodate really large or odd aspect ratios, create specific folders for these as well, using the flags for this, eg. sw, long, large, etc.
• And no need to draw the background twice. Therefore set a style with <item name="android:windowBackground">@null</item>

I agree - it's probably safer to use a GET request if you're just passing data in the URL and not in the body. See this similar question for some additional views on the whole POST+GET concept.

I had a similar requirement to this but my replace var contained an ampersand. Escaping the ampersand like this solved my problem:

replace="salt & pepper"
echo "pass the salt" | sed "s/salt/${replace/&/\&}/g"

On a Windows system, you can use free FileTimes library.

This will be easier in the future with Java NIO.2 (JDK 7) and the java.nio.file.attribute package.

But remember that most Linux filesystems don't support file creation timestamps.

I would recommend to use date->diff function, as in example below:

   $dStart = new DateTime('2012-07-26');
   $dEnd  = new DateTime('2012-08-26');
   $dDiff = $dStart->diff($dEnd);
   echo $dDiff->format('%r%a'); // use for point out relation: smaller/greater

see http://www.php.net/manual/en/datetime.diff.php

As of Laravel >= 5.3, best way is to use value:

$groupName = \App\User::where('username',$username)->value('groupName');

or

use App\User;//at top of controller
$groupName = User::where('username',$username)->value('groupName');//inside controller function

Of course you have to create a model User for users table which is most efficient way to interact with database tables in Laravel.

This helped me delete data based on different attributes. This is dangerous so make sure you back up database or the table before doing it:

mysqldump -h hotsname -u username -p password database_name > backup_folder/backup_filename.txt

Now you can perform the delete operation:

delete from table_name where column_name < DATE_SUB(NOW() , INTERVAL 1 DAY)

This will remove all the data from before one day. For deleting data from before 6 months:

delete from table_name where column_name < DATE_SUB(NOW() , INTERVAL 6 MONTH)

If you always want it to go to /C, use an absolute path when you write the file.

The most Pythonic way is to use the len(). Keep in mind that the '\' character in escape sequences is not counted and can be dangerous if not used correctly.

>>> len('foo')
3
>>> len('\foo')
3
>>> len('\xoo')
  File "<stdin>", line 1
SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 0-1: truncated \xXX escape

Since keys are what dictionaries use to lookup values, you can't really change them. The closest thing you can do is to save the value associated with the old key, delete it, then add a new entry with the replacement key and the saved value. Several of the other answers illustrate different ways this can be accomplished.

When creating a New Project, under the language of your choice, select Web and then change to .NET Framework 3.5 and you will get the option of creating an ASP.NET WEB Service Application.

5 years have passed and this essential requirement didn't get ignored by the Chrome devs.
While they offer no method to edit the data like in Firefox, they offer a full XHR replay.
This allows to debug ajax calls.

"Replay XHR" will repeat the entire transmission.

Instead of:

df2 = df1.filter("Status=2" || "Status =3")

Try:

df2 = df1.filter($"Status" === 2 || $"Status" === 3)

Call make this way

make CFLAGS=-Dvar=42

because you do want to override your Makefile's CFLAGS, and not just the environment (which has a lower priority with regard to Makefile variables).

You could use regular expressions.

You can detect digits using:

if(re.search([0-9], yourstring[:1])):
#do something

The [0-9] par matches any digit, and yourstring[:1] matches the first character of your string

If you want to input a description you can use this. This works on IE 9 and all other browsers.

<input type="text" onclick="if(this.value=='CVC2: '){this.value='';}" onblur="if(this.value==''){this.value='CVC2: ';}" value="CVC2: "/>

Differences in SOAP versions

Both SOAP Version 1.1 and SOAP Version 1.2 are World Wide Web Consortium (W3C) standards. Web services can be deployed that support not only SOAP 1.1 but also support SOAP 1.2. Some changes from SOAP 1.1 that were made to the SOAP 1.2 specification are significant, while other changes are minor.

The SOAP 1.2 specification introduces several changes to SOAP 1.1. This information is not intended to be an in-depth description of all the new or changed features for SOAP 1.1 and SOAP 1.2. Instead, this information highlights some of the more important differences between the current versions of SOAP.

The changes to the SOAP 1.2 specification that are significant include the following updates: SOAP 1.1 is based on XML 1.0. SOAP 1.2 is based on XML Information Set (XML Infoset). The XML information set (infoset) provides a way to describe the XML document with XSD schema. However, the infoset does not necessarily serialize the document with XML 1.0 serialization on which SOAP 1.1 is based.. This new way to describe the XML document helps reveal other serialization formats, such as a binary protocol format. You can use the binary protocol format to compact the message into a compact format, where some of the verbose tagging information might not be required.

In SOAP 1.2 , you can use the specification of a binding to an underlying protocol to determine which XML serialization is used in the underlying protocol data units. The HTTP binding that is specified in SOAP 1.2 - Part 2 uses XML 1.0 as the serialization of the SOAP message infoset.

SOAP 1.2 provides the ability to officially define transport protocols, other than using HTTP, as long as the vendor conforms to the binding framework that is defined in SOAP 1.2. While HTTP is ubiquitous, it is not as reliable as other transports including TCP/IP and MQ. SOAP 1.2 provides a more specific definition of the SOAP processing model that removes many of the ambiguities that might lead to interoperability errors in the absence of the Web Services-Interoperability (WS-I) profiles. The goal is to significantly reduce the chances of interoperability issues between different vendors that use SOAP 1.2 implementations. SOAP with Attachments API for Java (SAAJ) can also stand alone as a simple mechanism to issue SOAP requests. A major change to the SAAJ specification is the ability to represent SOAP 1.1 messages and the additional SOAP 1.2 formatted messages. For example, SAAJ Version 1.3 introduces a new set of constants and methods that are more conducive to SOAP 1.2 (such as getRole(), getRelay()) on SOAP header elements. There are also additional methods on the factories for SAAJ to create appropriate SOAP 1.1 or SOAP 1.2 messages. The XML namespaces for the envelope and encoding schemas have changed for SOAP 1.2. These changes distinguish SOAP processors from SOAP 1.1 and SOAP 1.2 messages and supports changes in the SOAP schema, without affecting existing implementations. Java Architecture for XML Web Services (JAX-WS) introduces the ability to support both SOAP 1.1 and SOAP 1.2. Because JAX-RPC introduced a requirement to manipulate a SOAP message as it traversed through the run time, there became a need to represent this message in its appropriate SOAP context. In JAX-WS, a number of additional enhancements result from the support for SAAJ 1.3.

There is not difine POST AND GET method for particular android....but all here is differance

GET The GET method appends name/value pairs to the URL, allowing you to retrieve a resource representation. The big issue with this is that the length of a URL is limited (roughly 3000 char) resulting in data loss should you have to much stuff in the form on your page, so this method only works if there is a small number parameters.

What does this mean for me? Basically this renders the GET method worthless to most developers in most situations. Here is another way of looking at it: the URL could be truncated (and most likely will be give today's data-centric sites) if the form uses a large number of parameters, or if the parameters contain large amounts of data. Also, parameters passed on the URL are visible in the address field of the browser (YIKES!!!) not the best place for any kind of sensitive (or even non-sensitive) data to be shown because you are just begging the curious user to mess with it.

POST The alternative to the GET method is the POST method. This method packages the name/value pairs inside the body of the HTTP request, which makes for a cleaner URL and imposes no size limitations on the forms output, basically its a no-brainer on which one to use. POST is also more secure but certainly not safe. Although HTTP fully supports CRUD, HTML 4 only supports issuing GET and POST requests through its various elements. This limitation has held Web applications back from making full use of HTTP, and to work around it, most applications overload POST to take care of everything but resource retrieval.

I would just go with

<tr @(if (count++ % 2 == 0){<text>class="alt-row"</text>})>

Or even better

<tr class="alt-row@(count++ % 2)">

this will give you lines like

<tr class="alt-row0">
<tr class="alt-row1">
<tr class="alt-row0">
<tr class="alt-row1">

You can do that using the descendant selectors:

I was looking for an easier-to-read time-loop when I encountered this question here. Something like:

for sec in max_seconds(10):
      do_something()

So I created this helper:

# allow easy time-boxing: 'for sec in max_seconds(42): do_something()'
def max_seconds(max_seconds, *, interval=1):
    interval = int(interval)
    start_time = time.time()
    end_time = start_time + max_seconds
    yield 0
    while time.time() < end_time:
        if interval > 0:
            next_time = start_time
            while next_time < time.time():
                next_time += interval
            time.sleep(int(round(next_time - time.time())))
        yield int(round(time.time() - start_time))
        if int(round(time.time() + interval)) > int(round(end_time)): 
            return

It only works with full seconds which was OK for my use-case.

Examples:

for sec in max_seconds(10) # -> 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10
for sec in max_seconds(10, interval=3) # -> 0, 3, 6, 9
for sec in max_seconds(7): sleep(1.5) # -> 0, 2, 4, 6
for sec in max_seconds(8): sleep(1.5) # -> 0, 2, 4, 6, 8

Be aware that interval isn't that accurate, as I only wait full seconds (sleep never was any good for me with times < 1 sec). So if your job takes 500 ms and you ask for an interval of 1 sec, you'll get called at: 0, 500ms, 2000ms, 2500ms, 4000ms and so on. One could fix this by measuring time in a loop rather than sleep() ...

Read MSDN.

it also contains a link to the args.

short answer: no, the main does not get override. when visual studio (actually the compiler) builds your exe it must declare a starting point for the assmebly, that point is the main function.

if you meant how to literary pass args then you can either run you're app from the command line with them (e.g. appname.exe param1 param2) or in the project setup, enter them (in the command line arguments in the Debug tab)

in the main you will need to read those args for example:

for (int i = 0; i < args.Length; i++)
{
    string flag = args.GetValue(i).ToString();
    if (flag == "bla") 
    {
        Bla();
    }
}

You actually can use sed to do it, provided it is GNU sed.

... | sed 's/match/command \0/e'

How it works:

1. Substitute match with command match
2. On substitution execute command
3. Replace substituted line with command output.

sp_who2 will actually provide a list of connections for the database server, not a database. To view connections for a single database (YourDatabaseName in this example), you can use

DECLARE @AllConnections TABLE(
    SPID INT,
    Status VARCHAR(MAX),
    LOGIN VARCHAR(MAX),
    HostName VARCHAR(MAX),
    BlkBy VARCHAR(MAX),
    DBName VARCHAR(MAX),
    Command VARCHAR(MAX),
    CPUTime INT,
    DiskIO INT,
    LastBatch VARCHAR(MAX),
    ProgramName VARCHAR(MAX),
    SPID_1 INT,
    REQUESTID INT
)

INSERT INTO @AllConnections EXEC sp_who2

SELECT * FROM @AllConnections WHERE DBName = 'YourDatabaseName'

(Adapted from SQL Server: Filter output of sp_who2.)

If you don't support legacy browsers, I'd use flexbox because it's well supported and will simply solve most of your layout problems.

#table-id td:nth-child(1) { 
    /* nth-child(1) is the first column, change to fit your needs */
    display: flex;
    justify-content: center;
}

This centers all content in the first <td> of every row.

jQuery has very limited array functions since JavaScript has most of them itself. But here are the ones they have: Utilities - jQuery API.

XPath has a contains-token function, specifically designed for this situation:

//div[contains-token(@class, 'Test')]

It's only supported in the latest version of XPath (3.1) so you'll need an up-to-date implementation.

If you want to sort by something like creation date you probably need to use DirectoryInfo.GetFiles and then sort the resulting array using a suitable Predicate.

ContactNumbers = new List<ContactNumber>();

If you want it to be passed in, just take

public Human(List<ContactNumber> numbers)
{
 ContactNumbers = numbers;
}

try bind(this) so your code looks like below --

 <a className="upvotes" onClick={this.upvote.bind(this)}>upvote</a>

or if you are writing in es6 react component in constructor you could do this

constructor(props){
   super(props);
   this.upvote = this.upvote.bind(this);
}

upvote(e){   // function upvote
   e.preventDefault();
   return false

}

The other answers have done a good job at explaining duck typing and the simple answer by tzot:

Python does not have variables, like other languages where variables have a type and a value; it has names pointing to objects, which know their type.

However, one interesting thing has changed since 2010 (when the question was first asked), namely the implementation of PEP 3107 (implemented in Python 3). You can now actually specify the type of a parameter and the type of the return type of a function like this:

def pick(l: list, index: int) -> int:
    return l[index]

We can here see that pick takes 2 parameters, a list l and an integer index. It should also return an integer.

So here it is implied that l is a list of integers which we can see without much effort, but for more complex functions it can be a bit confusing as to what the list should contain. We also want the default value of index to be 0. To solve this you may choose to write pick like this instead:

def pick(l: "list of ints", index: int = 0) -> int:
    return l[index]

Note that we now put in a string as the type of l, which is syntactically allowed, but it is not good for parsing programmatically (which we'll come back to later).

It is important to note that Python won't raise a TypeError if you pass a float into index, the reason for this is one of the main points in Python's design philosophy: "We're all consenting adults here", which means you are expected to be aware of what you can pass to a function and what you can't. If you really want to write code that throws TypeErrors you can use the isinstance function to check that the passed argument is of the proper type or a subclass of it like this:

def pick(l: list, index: int = 0) -> int:
    if not isinstance(l, list):
        raise TypeError
    return l[index]

More on why you should rarely do this and what you should do instead is talked about in the next section and in the comments.

PEP 3107 does not only improve code readability but also has several fitting use cases which you can read about here.

Type annotation got a lot more attention in Python 3.5 with the introduction of PEP 484 which introduces a standard module for type hints.

These type hints came from the type checker mypy (GitHub), which is now PEP 484 compliant.

With the typing module comes with a pretty comprehensive collection of type hints, including:

• List, Tuple, Set, Map - for list, tuple, set and map respectively.
• Iterable - useful for generators.
• Any - when it could be anything.
• Union - when it could be anything within a specified set of types, as opposed to Any.
• Optional - when it might be None. Shorthand for Union[T, None].
• TypeVar - used with generics.
• Callable - used primarily for functions, but could be used for other callables.

These are the most common type hints. A complete listing can be found in the documentation for the typing module.

Here is the old example using the annotation methods introduced in the typing module:

from typing import List

def pick(l: List[int], index: int) -> int:
    return l[index]

One powerful feature is the Callable which allows you to type annotate methods that take a function as an argument. For example:

from typing import Callable, Any, Iterable

def imap(f: Callable[[Any], Any], l: Iterable[Any]) -> List[Any]:
    """An immediate version of map, don't pass it any infinite iterables!"""
    return list(map(f, l))

The above example could become more precise with the usage of TypeVar instead of Any, but this has been left as an exercise to the reader since I believe I've already filled my answer with too much information about the wonderful new features enabled by type hinting.

Previously when one documented Python code with for example Sphinx some of the above functionality could be obtained by writing docstrings formatted like this:

def pick(l, index):
    """
    :param l: list of integers
    :type l: list
    :param index: index at which to pick an integer from *l*
    :type index: int
    :returns: integer at *index* in *l*
    :rtype: int
    """
    return l[index]

As you can see, this takes a number of extra lines (the exact number depends on how explicit you want to be and how you format your docstring). But it should now be clear to you how PEP 3107 provides an alternative that is in many (all?) ways superior. This is especially true in combination with PEP 484 which, as we have seen, provides a standard module that defines a syntax for these type hints/annotations that can be used in such a way that it is unambiguous and precise yet flexible, making for a powerful combination.

In my personal opinion, this is one of the greatest features in Python ever. I can't wait for people to start harnessing the power of it. Sorry for the long answer, but this is what happens when I get excited.

An example of Python code which heavily uses type hinting can be found here.

In case you need to parse it from a file, I find the best solution to use a HashMap<String, String> to use it inside your java code for better manipultion.

Try out this code:

public HashMap<String, String> myMethodName() throws FileNotFoundException
{
    String path = "absolute path to your file";
    BufferedReader bufferedReader = new BufferedReader(new FileReader(path));

    Gson gson = new Gson();
    HashMap<String, String> json = gson.fromJson(bufferedReader, HashMap.class);
    return json;
}

You could use viewport units here instead of %. Like this:

iframe {
    max-width: 100vw;
    max-height: 56.25vw; /* height/width ratio = 315/560 = .5625 */
}

Arel is your friend:

I think creating a class to simulate C-like structs, like you've been doing, is the best way.

It's a great way to group related data and simplifies passing parameters to functions. I'd also argue that a JavaScript class is more like a C++ struct than a C++ class, considering the added effort needed to simulate real object oriented features.

I've found that trying to make JavaScript more like another language gets complicated fast, but I fully support using JavaScript classes as functionless structs.

In many case you will need to add the bodyParser module in your express node app. Then in your app.use part below app.use(express.static('www')); add these 2 lines app.use(bodyParser.urlencoded({ extended: true })); app.use(bodyParser.json());

pyspark version:

  df = <source data>
  df.printSchema()

  from pyspark.sql.types import *

  # Change column type
  df_new = df.withColumn("myColumn", df["myColumn"].cast(IntegerType()))
  df_new.printSchema()
  df_new.select("myColumn").show()

Hibernate, because it's basically the defacto standard in Java and was one of the driving forces in the creation of the JPA. It's got excellent support in Spring, and almost every Java framework supports it. Finally, GORM is a really cool wrapper around it doing dynamic finders and so on using Groovy.

It's even been ported to .NET (NHibernate) so you can use it there too.

Try to do something like this:

db.getCollection('collectionName').find({'ArrayName.1': {$exists: true}})

1 is number, if you want to fetch record greater than 50 then do ArrayName.50 Thanks.

Try to implement FirebaseInstanceIdService to get refresh token.

Access the registration token:

You can access the token's value by extending FirebaseInstanceIdService. Make sure you have added the service to your manifest, then call getToken in the context of onTokenRefresh, and log the value as shown:

     @Override
public void onTokenRefresh() {
    // Get updated InstanceID token.
    String refreshedToken = FirebaseInstanceId.getInstance().getToken();
    Log.d(TAG, "Refreshed token: " + refreshedToken);

    // TODO: Implement this method to send any registration to your app's servers.
    sendRegistrationToServer(refreshedToken);
}

Full Code:

   import android.util.Log;

import com.google.firebase.iid.FirebaseInstanceId;
import com.google.firebase.iid.FirebaseInstanceIdService;


public class MyFirebaseInstanceIDService extends FirebaseInstanceIdService {

    private static final String TAG = "MyFirebaseIIDService";

    /**
     * Called if InstanceID token is updated. This may occur if the security of
     * the previous token had been compromised. Note that this is called when the InstanceID token
     * is initially generated so this is where you would retrieve the token.
     */
    // [START refresh_token]
    @Override
    public void onTokenRefresh() {
        // Get updated InstanceID token.
        String refreshedToken = FirebaseInstanceId.getInstance().getToken();
        Log.d(TAG, "Refreshed token: " + refreshedToken);

        // TODO: Implement this method to send any registration to your app's servers.
        sendRegistrationToServer(refreshedToken);
    }
    // [END refresh_token]

    /**
     * Persist token to third-party servers.
     *
     * Modify this method to associate the user's FCM InstanceID token with any server-side account
     * maintained by your application.
     *
     * @param token The new token.
     */
    private void sendRegistrationToServer(String token) {
        // Add custom implementation, as needed.
    }
}

See my answer here.

EDITS:

You shouldn't be starting a FirebaseInstanceIdService yourself.

It will Called when the system determines that the tokens need to be refreshed. The application should call getToken() and send the tokens to all application servers.

This will not be called very frequently, it is needed for key rotation and to handle Instance ID changes due to:

• App deletes Instance ID
• App is restored on a new device User
• uninstalls/reinstall the app
• User clears app data

The system will throttle the refresh event across all devices to avoid overloading application servers with token updates.

Try below way:

you'd call FirebaseInstanceID.getToken() anywhere off your main thread (whether it is a service, AsyncTask, etc), store the returned token locally and send it to your server. Then whenever onTokenRefresh() is called, you'd call FirebaseInstanceID.getToken() again, get a new token, and send that up to the server (probably including the old token as well so your server can remove it, replacing it with the new one).

If I can throw my hat into the ring, I think there is a cleaner way than the existing answers to reuse the radio button functionality.

Let's say you have the following property in your ViewModel:

Public Class ViewModel
    <Display(Name:="Do you like Cats?")>
    Public Property LikesCats As Boolean
End Class

You can expose that property through a reusable editor template:

First, create the file Views/Shared/EditorTemplates/YesNoRadio.vbhtml

Then add the following code to YesNoRadio.vbhtml:

@ModelType Boolean?

<fieldset>
    <legend>
        @Html.LabelFor(Function(model) model)
    </legend>

    <label>
        @Html.RadioButtonFor(Function(model) model, True) Yes
    </label>
    <label>
        @Html.RadioButtonFor(Function(model) model, False) No
    </label>
</fieldset>

You can call the editor for the property by manually specifying the template name in your View:

@Html.EditorFor(Function(model) model.LikesCats, "YesNoRadio")

Pros:

• Get to write HTML in an HTML editor instead of appending strings in code behind.
• Preserves the DisplayName DataAnnotation
• Allows clicks on Label to toggle radio button
• Least possible code to maintain in form (1 line). If something is wrong with the way it is rending, take it up with the template.

I experienced the same issues as Harry Johnston has mentioned. rmdir /s /q would complain that a directory was not empty even though /s is meant to do the emptying for you! I think it's a bug in Windows, personally.

My workaround is to del everything in the directory before deleting the directory itself:

del /f /s /q mydir 1>nul
rmdir /s /q mydir

(The 1>nul hides the standard output of del because otherwise, it lists every single file it deletes.)

I have had the same problem in my project. I used an IntelliJ Idea 14 and Maven 8. And what I've noticed is that when I added a tomcat destination to to IDE it automaticly linked two jars from tomcat lib directory, they were servlet-api and jsp-api. Also I had them in my pom.xml. I killed a whole day trying to figure out why I'm getting java.lang.ClassNotFoundException: org.apache.jsp.index_jsp. And kewpiedoll99 is right. That is because there are dependency conflicts. When I added provided to those two jars in my pom.xml I found a happiness :)

If you do not use precompiled headers in your project, set the Create/Use Precompiled Header property of source files to Not Using Precompiled Headers. To set this compiler option, follow these steps:

• In the Solution Explorer pane of the project, right-click the project name, and then click Properties.
• In the left pane, click the C/C++ folder.
• Click the Precompiled Headers node.
• In the right pane, click Create/Use Precompiled Header, and then click Not Using Precompiled Headers.

Make sure the directory name is lower case.

The 'actual answer' is that you cannot do it directly. You have to convert your PowerPoint presentation to something that the browser can process. You can save each page of the PowerPoint presentation as a JPEG image and then display as a series of images. You can save the PowerPoint presentation as HTML. Both of these solutions will render only static pages, without any of the animations of PowerPoint. You can use a tool to convert your PowerPoint presentation to Flash (.swf) and embed it that way. This will preserve any animations and presumably allow you to do an automatic slideshow without the need for writing special code to change the images.

There is no guarantee that a GUID contains alpha characters. FFFFFFFF-FFFF-FFFF-FFFF-FFFFFFFFFFFF is a valid GUID so is 00000000-0000-0000-0000-000000000000 and anything in between.

If you are using .NET 4.0, you can use the answer above for the Guid.Parse and Guid.TryParse. Otherwise, you can do something like this:

public static bool TryParseGuid(string guidString, out Guid guid)
{
    if (guidString == null) throw new ArgumentNullException("guidString");
    try
    {
        guid = new Guid(guidString);
        return true;
    }
    catch (FormatException)
    {
        guid = default(Guid);
        return false;
    }
}

Actually I don't know you want to this.

try this

INSERT INTO my_table (my_column)
SELECT
    (random() * 10) + 1
;

Assuming the question is about accessing files in the application folder after the ClickOnce (true == System.Deployment.ApplicationDeploy.IsNetworkDeployed) application is installed on the user's PC, their are three ways to get this folder by the application itself:

String path1 = System.AppDomain.CurrentDomain.BaseDirectory;
String path2 = System.IO.Directory.GetCurrentDirectory();    
String path3 = System.Reflection.Assembly.GetExecutingAssembly().CodeBase; //Remove the last path component, the executing assembly itself.

These work from VS IDE and from a deployed/installed ClickedOnce app, no "true == System.Deployment.ApplicationDeploy.IsNetworkDeployed" check required. ClickOnce picks up any files included in the Visual Studio 2017 project so really the application can access any and all deployed files using relative paths from within the application.

This is based on Windows 10 and Visual Studio 2017

I'm not sure if I'm answering the question right, but here's a familiar example:

The return type of GetLastError() in Windows is nonzero if there was an error, or zero otherwise. The reverse is usually true of the return value of the function you called.

Use 'dd-mon-yyyy' if you are using the 2nd date format specified in your answer. Ex:

to_date(<column name>,'dd-mon-yyyy')

Spark RDD (resilient distributed dataset) :

RDD is the core data abstraction API and is available since very first release of Spark (Spark 1.0). It is a lower-level API for manipulating distributed collection of data. The RDD APIs exposes some extremely useful methods which can be used to get very tight control over underlying physical data structure. It is an immutable (read only) collection of partitioned data distributed on different machines. RDD enables in-memory computation on large clusters to speed up big data processing in a fault tolerant manner. To enable fault tolerance, RDD uses DAG (Directed Acyclic Graph) which consists of a set of vertices and edges. The vertices and edges in DAG represent the RDD and the operation to be applied on that RDD respectively. The transformations defined on RDD are lazy and executes only when an action is called

Spark DataFrame :

Spark 1.3 introduced two new data abstraction APIs – DataFrame and DataSet. The DataFrame APIs organizes the data into named columns like a table in relational database. It enables programmers to define schema on a distributed collection of data. Each row in a DataFrame is of object type row. Like an SQL table, each column must have same number of rows in a DataFrame. In short, DataFrame is lazily evaluated plan which specifies the operations needs to be performed on the distributed collection of the data. DataFrame is also an immutable collection.

Spark DataSet :

As an extension to the DataFrame APIs, Spark 1.3 also introduced DataSet APIs which provides strictly typed and object-oriented programming interface in Spark. It is immutable, type-safe collection of distributed data. Like DataFrame, DataSet APIs also uses Catalyst engine in order to enable execution optimization. DataSet is an extension to the DataFrame APIs.

Other Differences -

You can simply use setInterval to create such timer in Angular, Use this Code for timer -

timeLeft: number = 60;
  interval;

startTimer() {
    this.interval = setInterval(() => {
      if(this.timeLeft > 0) {
        this.timeLeft--;
      } else {
        this.timeLeft = 60;
      }
    },1000)
  }

  pauseTimer() {
    clearInterval(this.interval);
  }

<button (click)='startTimer()'>Start Timer</button>
<button (click)='pauseTimer()'>Pause</button>

<p>{{timeLeft}} Seconds Left....</p>

Working Example

Another way using Observable timer like below -

import { timer } from 'rxjs';

observableTimer() {
    const source = timer(1000, 2000);
    const abc = source.subscribe(val => {
      console.log(val, '-');
      this.subscribeTimer = this.timeLeft - val;
    });
  }

<p (click)="observableTimer()">Start Observable timer</p> {{subscribeTimer}}

Working Example

For more information read here

Based on a comment in another answer, here's my shell function.

# mvp = move + create parents
function mvp () {
    source="$1"
    target="$2"
    target_dir="$(dirname "$target")"
    mkdir --parents $target_dir; mv $source $target
}

Include this in .bashrc or similar so you can use it everywhere.

For exact concatenation operation of two string please use:

file_names = file_names.concat(file_names1);

In your case use + instead of .

another option (in place, any combination of indices):

_marker = object()

for i in indices:
    my_list[i] = _marker  # marked for deletion

obj[:] = [v for v in my_list if v is not _marker]

Yeah it is possible with FileReader, I have already done an example of this, here's the code:

<!DOCTYPE html>
<html>
  <head>
    <title>Read File (via User Input selection)</title>
    <script type="text/javascript">
    var reader; //GLOBAL File Reader object for demo purpose only

    /**
     * Check for the various File API support.
     */
    function checkFileAPI() {
        if (window.File && window.FileReader && window.FileList && window.Blob) {
            reader = new FileReader();
            return true; 
        } else {
            alert('The File APIs are not fully supported by your browser. Fallback required.');
            return false;
        }
    }

    /**
     * read text input
     */
    function readText(filePath) {
        var output = ""; //placeholder for text output
        if(filePath.files && filePath.files[0]) {           
            reader.onload = function (e) {
                output = e.target.result;
                displayContents(output);
            };//end onload()
            reader.readAsText(filePath.files[0]);
        }//end if html5 filelist support
        else if(ActiveXObject && filePath) { //fallback to IE 6-8 support via ActiveX
            try {
                reader = new ActiveXObject("Scripting.FileSystemObject");
                var file = reader.OpenTextFile(filePath, 1); //ActiveX File Object
                output = file.ReadAll(); //text contents of file
                file.Close(); //close file "input stream"
                displayContents(output);
            } catch (e) {
                if (e.number == -2146827859) {
                    alert('Unable to access local files due to browser security settings. ' + 
                     'To overcome this, go to Tools->Internet Options->Security->Custom Level. ' + 
                     'Find the setting for "Initialize and script ActiveX controls not marked as safe" and change it to "Enable" or "Prompt"'); 
                }
            }       
        }
        else { //this is where you could fallback to Java Applet, Flash or similar
            return false;
        }       
        return true;
    }   

    /**
     * display content using a basic HTML replacement
     */
    function displayContents(txt) {
        var el = document.getElementById('main'); 
        el.innerHTML = txt; //display output in DOM
    }   
</script>
</head>
<body onload="checkFileAPI();">
    <div id="container">    
        <input type="file" onchange='readText(this)' />
        <br/>
        <hr/>   
        <h3>Contents of the Text file:</h3>
        <div id="main">
            ...
        </div>
    </div>
</body>
</html>

It's also possible to do the same thing to support some older versions of IE (I think 6-8) using the ActiveX Object, I had some old code which does that too but its been a while so I'll have to dig it up I've found a solution similar to the one I used courtesy of Jacky Cui's blog and edited this answer (also cleaned up code a bit). Hope it helps.

Lastly, I just read some other answers that beat me to the draw, but as they suggest, you might be looking for code that lets you load a text file from the server (or device) where the JavaScript file is sitting. If that's the case then you want AJAX code to load the document dynamically which would be something as follows:

<!DOCTYPE html>
<html>
<head><meta charset="utf-8" />
<title>Read File (via AJAX)</title>
<script type="text/javascript">
var reader = new XMLHttpRequest() || new ActiveXObject('MSXML2.XMLHTTP');

function loadFile() {
    reader.open('get', 'test.txt', true); 
    reader.onreadystatechange = displayContents;
    reader.send(null);
}

function displayContents() {
    if(reader.readyState==4) {
        var el = document.getElementById('main');
        el.innerHTML = reader.responseText;
    }
}

</script>
</head>
<body>
<div id="container">
    <input type="button" value="test.txt"  onclick="loadFile()" />
    <div id="main">
    </div>
</div>
</body>
</html>

Using click function:

$('.btn-editUser').on('click', function(){
    $('#viewUser').modal('hide'); // hides modal with id viewUser 
    $('#editUser').modal('show'); // display modal with id editUser
});

Heads up:

Make sure that the one you want to show is an independent modal.

As a very simple solution to this, I did the following:

1) Add the following CSS:

.sub_step_info .popover::after {
    content:url('/images/cross.png');
    position:absolute;
    display:inline-block;
    top:15px;
    right:5px;
    width:15px;
    text-align:center;
    cursor:pointer;
}

2) Set data-trigger="manual" on the popover trigger element

3) Then based on https://github.com/twbs/bootstrap/issues/16802:

$('[data-trigger="manual"]').click(function() {
    $(this).popover('toggle');
}).blur(function() {
    $(this).popover('hide');
}); 

This uses the basis that anywhere on the popover is clickable but by focusing on the cross you'll encourage the behaviour you're after.

public static double addDoubles(double a, double b) {
        BigDecimal A = new BigDecimal(a + "");
        BigDecimal B = new BigDecimal(b + "");
        return A.add(B).setScale(2, BigDecimal.ROUND_HALF_UP).doubleValue();
    }

grep -e -X will do the trick.

Here are two options to emulate the needed behavior. Not a general solution, but may help in some cases. The vertical spacing here is calculated on the basis of the size of the outer element, not its parent, but this size itself can be relative to the parent and this way the spacing will be relative too.

<div id="outer">
    <div id="inner">
        content
    </div>
</div>

First option: use pseudo-elements, here vertical and horizontal spacing are relative to the outer. Demo

#outer::before, #outer::after {
    display: block;
    content: "";
    height: 10%;
}
#inner {
    height: 80%;
    margin-left: 10%;
    margin-right: 10%;
}

Moving the horizontal spacing to the outer element makes it relative to the parent of the outer. Demo

#outer {
    padding-left: 10%;
    padding-right: 10%;
}

Second option: use absolute positioning. Demo

#outer {
    position: relative;
}
#inner {
    position: absolute;
    left: 10%;
    right: 10%;
    top: 10%;
    bottom: 10%;
}

Run ipconfig /flushdns from a command prompt. Apparently some people seem to think I posted this answer for sheer fun. That's why they down voted my answer. Perhaps an explanation would help them. When I used "SVN Update" it said it can't connect to the SVN repository although I could ping the server. After running ipconfig /flushdns the issue was fixed.

Short answer: Use the change event. Here's a couple of practical examples. Since I misread the question, I'll include jQuery examples along with plain JavaScript. You're not gaining much, if anything, by using jQuery though.

Single checkbox

Using querySelector.

var checkbox = document.querySelector("input[name=checkbox]");

checkbox.addEventListener('change', function() {
  if (this.checked) {
    console.log("Checkbox is checked..");
  } else {
    console.log("Checkbox is not checked..");
  }
});

<input type="checkbox" name="checkbox" />

Single checkbox with jQuery

$('input[name=checkbox]').change(function() {
  if ($(this).is(':checked')) {
    console.log("Checkbox is checked..")
  } else {
    console.log("Checkbox is not checked..")
  }
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

<input type="checkbox" name="checkbox" />

Multiple checkboxes

Here's an example of a list of checkboxes. To select multiple elements we use querySelectorAll instead of querySelector. Then use Array.filter and Array.map to extract checked values.

// Select all checkboxes with the name 'settings' using querySelectorAll.
var checkboxes = document.querySelectorAll("input[type=checkbox][name=settings]");
let enabledSettings = []

/*
For IE11 support, replace arrow functions with normal functions and
use a polyfill for Array.forEach:
https://vanillajstoolkit.com/polyfills/arrayforeach/
*/

// Use Array.forEach to add an event listener to each checkbox.
checkboxes.forEach(function(checkbox) {
  checkbox.addEventListener('change', function() {
    enabledSettings = 
      Array.from(checkboxes) // Convert checkboxes to an array to use filter and map.
      .filter(i => i.checked) // Use Array.filter to remove unchecked checkboxes.
      .map(i => i.value) // Use Array.map to extract only the checkbox values from the array of objects.
      
    console.log(enabledSettings)
  })
});

<label>
   <input type="checkbox" name="settings" value="forcefield">
   Enable forcefield
</label>
<label>
  <input type="checkbox" name="settings" value="invisibilitycloak">
  Enable invisibility cloak
</label>
<label>
  <input type="checkbox" name="settings" value="warpspeed">
  Enable warp speed
</label>

Multiple checkboxes with jQuery

let checkboxes = $("input[type=checkbox][name=settings]")
let enabledSettings = [];

// Attach a change event handler to the checkboxes.
checkboxes.change(function() {
  enabledSettings = checkboxes
    .filter(":checked") // Filter out unchecked boxes.
    .map(function() { // Extract values using jQuery map.
      return this.value;
    }) 
    .get() // Get array.
    
  console.log(enabledSettings);
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<label>
   <input type="checkbox" name="settings" value="forcefield">
   Enable forcefield
</label>
<label>
  <input type="checkbox" name="settings" value="invisibilitycloak">
  Enable invisibility cloak
</label>
<label>
  <input type="checkbox" name="settings" value="warpspeed">
  Enable warp speed
</label>

Maybe try the Intl polyfill for IE8 or the olyfill service ?

The commandline interpreter does indeed have a FOR construct that you can use from the command prompt or from within a batch file.

For your purpose, you probably want something like:

FOR %i IN (*.ext) DO my-function %i

Which will result in the name of each file with extension *.ext in the current directory being passed to my-function (which could, for example, be another .bat file).

The (*.ext) part is the "filespec", and is pretty flexible with how you specify sets of files. For example, you could do:

FOR %i IN (C:\Some\Other\Dir\*.ext) DO my-function %i

To perform an operation in a different directory.

There are scores of options for the filespec and FOR in general. See

HELP FOR

from the command prompt for more information.

I'm writing an sp that could be useful for this purpose, basically this sp pivot any table and return a new table pivoted or return just the set of data, this is the way to execute it:

My solution was to select the maven profiles I had defined in my pom.xml in which I had declared the hibernate dependencies.

CTRL + ALT + P in eclipse.

In my project I was experiencing this problem and many others because in my pom I have different profiles for supporting Glassfish 3, Glassfish 4 and also WildFly so I have differet versions of Hibernate per container as well as different Java compilation targets and so on. Selecting the active maven profiles resolved my issue.

The answer that helped me: The directive [(ngModel)]= not working anymore in rc5

To sum it up: input fields now require property name in the form.

Use the casting operator (string)$yourObject;

You can use NestedScrollView instead of ScrollView. However, when using a Kotlin Lambda, it won't know you want NestedScrollView's setOnScrollChangeListener instead of the one at View (which is API level 23). You can fix this by specifying the first parameter as a NestedScrollView.

nestedScrollView.setOnScrollChangeListener { _: NestedScrollView, scrollX: Int, scrollY: Int, _: Int, _: Int ->
    Log.d("ScrollView", "Scrolled to $scrollX, $scrollY")
}

You should be able to Highlite text, hit "Enter" then Control V but this seems to be broken

HTML:

<div id="log"></div>

JS:

document.getElementById("log").innerHTML="WHATEVER YOU WANT...";

I was recently working with IPFS and worked this out. A curl example for IPFS to upload a file looks like this:

curl -i -H "Content-Type: multipart/form-data; boundary=CUSTOM" -d $'--CUSTOM\r\nContent-Type: multipart/octet-stream\r\nContent-Disposition: file; filename="test"\r\n\r\nHello World!\n--CUSTOM--' "http://localhost:5001/api/v0/add"

The basic idea is that each part (split by string in boundary with --) has it's own headers (Content-Type in the second part, for example.) The FormData object manages all this for you, so it's a better way to accomplish our goals.

This translates to fetch API like this:

const formData = new FormData()
formData.append('blob', new Blob(['Hello World!\n']), 'test')

fetch('http://localhost:5001/api/v0/add', {
  method: 'POST',
  body: formData
})
.then(r => r.json())
.then(data => {
  console.log(data)
})

For the case where the TextView is inside a TableLayout, the solution is to set android:shrinkColumns="1" on the TableLayout. (Replace 1 with the column number the TextView you want to wrap is in. (0-indexed))

AFAICT, no other attributes are needed on the TextView.

For other cases, see the other answers here.

FWIW, I had initially gotten it to sort of work with

 <TextView
   android:id="@+id/inventory_text"
   android:layout_width="fill_parent"
   android:layout_weight="1"
   android:width="0dp"

but that resulted in some extra empty space at the bottom of the Dialog it was all in.

When compiling memcached under Centos 5.x i got the same problem.

The solution is to upgrade gcc and g++ to version 4.4 at least.

Make sure your CC/CXX is set (exported) to right binaries before compiling.

I like the answer given here:

In short, the decision (in non-performance-critical apps) should be made on the basis of how you want to handle lookup of empty keys downstream (viz. KeyError versus default value).

They key is the backslash escape character will not work with the right square bracket inside of the character class square brackets (it is interpreted as a literal backslash inside the character class square brackets). Add the right square bracket with an OR at the end like this:

select EmpNo, SampleText
from test 
where NOT regexp_like(SampleText, '[ A-Za-z0-9.{}[]|]');

1. Use the carousel's indicators to display thumbnails.
2. Position the thumbnails outside of the main carousel with CSS.
3. Set the maximum height of the indicators to not be larger than the thumbnails.
4. Whenever the carousel has slid, update the position of the indicators, positioning the active indicator in the middle of the indicators.

I'm using this on my site (for example here), but I'm using some extra stuff to do lazy loading, meaning extracting the code isn't as straightforward as I would like it to be for putting it in a fiddle.

Also, my templating engine is smarty, but I'm sure you get the idea.

The meat...

Updating the indicators:

<ol class="carousel-indicators">
    {assign var='walker' value=0}
    {foreach from=$item["imagearray"] key="key" item="value"}
        <li data-target="#myCarousel" data-slide-to="{$walker}"{if $walker == 0} class="active"{/if}>
            <img src='http://farm{$value["farm"]}.static.flickr.com/{$value["server"]}/{$value["id"]}_{$value["secret"]}_s.jpg'>
        </li>

        {assign var='walker' value=1 + $walker}
    {/foreach}
</ol>

Changing the CSS related to the indicators:

.carousel-indicators {
    bottom:-50px;
    height: 36px;
    overflow-x: hidden;
    white-space: nowrap;
}

.carousel-indicators li {
    text-indent: 0;
    width: 34px !important;
    height: 34px !important;
    border-radius: 0;
}

.carousel-indicators li img {
    width: 32px;
    height: 32px;
    opacity: 0.5;
}

.carousel-indicators li:hover img, .carousel-indicators li.active img {
    opacity: 1;
}

.carousel-indicators .active {
    border-color: #337ab7;
}

When the carousel has slid, update the list of thumbnails:

$('#myCarousel').on('slid.bs.carousel', function() {
    var widthEstimate = -1 * $(".carousel-indicators li:first").position().left + $(".carousel-indicators li:last").position().left + $(".carousel-indicators li:last").width(); 
    var newIndicatorPosition = $(".carousel-indicators li.active").position().left + $(".carousel-indicators li.active").width() / 2;
    var toScroll = newIndicatorPosition + indicatorPosition;
    var adjustedScroll = toScroll - ($(".carousel-indicators").width() / 2);
    if (adjustedScroll < 0)
        adjustedScroll = 0;

    if (adjustedScroll > widthEstimate - $(".carousel-indicators").width())
        adjustedScroll = widthEstimate - $(".carousel-indicators").width();

    $('.carousel-indicators').animate({ scrollLeft: adjustedScroll }, 800);

    indicatorPosition = adjustedScroll;
});

And, when your page loads, set the initial scroll position of the thumbnails:

var indicatorPosition = 0;

I like this question and the answers to it, but so far there isn't coverage of less frequently used callbacks like onPostCreate() or onPostResume(). Steve Pomeroy has attempted a diagram including these and how they relate to Android's Fragment life cycle, at https://github.com/xxv/android-lifecycle. I revised Steve's large diagram to include only the Activity portion and formatted it for letter size one-page printout. I've posted it as a text PDF at https://github.com/code-read/android-lifecycle/blob/master/AndroidActivityLifecycle1.pdf and below is its image:

You use {} for grouping. The braces are required to dereference array elements. Example:

dir=(*)           # store the contents of the directory into an array
echo "${dir[0]}"  # get the first entry.
echo "$dir[0]"    # incorrect

Blinking !

var counter = 5; // Blinking the link 5 times
var $help = $('div.help');
var blinkHelp = function() {
    ($help.is(':visible') ? $help.fadeOut(250) : $help.fadeIn(250));    
    counter--;
    if (counter >= 0) setTimeout(blinkHelp, 500);
};
blinkHelp();

for ORA-01031: insufficient privileges. Some of the more common causes are:

1. You tried to change an Oracle username or password without having the appropriate privileges.
2. You tried to perform an UPDATE to a table, but you only have SELECT access to the table.
3. You tried to start up an Oracle database using CONNECT INTERNAL.
4. You tried to install an Oracle database without having the appropriate privileges to the operating-system.

The option(s) to resolve this Oracle error are:

1. You can have the Oracle DBA grant you the appropriate privileges that you are missing.
2. You can have the Oracle DBA execute the operation for you.
3. If you are having trouble starting up Oracle, you may need to add the Oracle user to the dba group.

For ORA-00942: table or view does not exist. You tried to execute a SQL statement that references a table or view that either does not exist, that you do not have access to, or that belongs to another schema and you didn't reference the table by the schema name.

If this error occurred because the table or view does not exist, you will need to create the table or view.

You can check to see if the table exists in Oracle by executing the following SQL statement:

select *
from all_objects
where object_type in ('TABLE','VIEW')
and object_name = 'OBJECT_NAME';

For example, if you are looking for a suppliers table, you would execute:

select *
from all_objects
where object_type in ('TABLE','VIEW')
and object_name = 'SUPPLIERS';

OPTION #2

If this error occurred because you do not have access to the table or view, you will need to have the owner of the table/view, or a DBA grant you the appropriate privileges to this object.

OPTION #3

If this error occurred because the table/view belongs to another schema and you didn't reference the table by the schema name, you will need to rewrite your SQL to include the schema name.

For example, you may have executed the following SQL statement:

select *
from suppliers;

But the suppliers table is not owned by you, but rather, it is owned by a schema called app, you could fix your SQL as follows:

select *
from app.suppliers;

If you do not know what schema the suppliers table/view belongs to, you can execute the following SQL to find out:

select owner
from all_objects
where object_type in ('TABLE','VIEW')
and object_name = 'SUPPLIERS';

This will return the schema name who owns the suppliers table.

You can first concatenate the strings in the list with the separator ';' using the function join and then use the split function in order create the list:

l = ['Facebook;Google+;MySpace', 'Apple;Android']

l1 = ";".join(l)).split(";")  

print l1

outputs

['Facebook', 'Google+', 'MySpace', 'Apple', 'Android']

You could also use...

$hostname = getenv('HTTP_HOST');
