You can use <properties> tag to define a custom variable and ${variable} pattern to use it

<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 http://maven.apache.org/maven-v4_0_0.xsd">

    </properties>

    <!-- using -->
    <version>${property.name}</version>

You can use following code

  DirectoryInfo di = Directory.CreateDirectory(path);

A quick search on the conda official docs will help you to find what each flag does.

So far:

• -y: Do not ask for confirmation.
• -f: I think it should be --file, so it read package versions from the given file.
• -q: Do not display progress bar.
• -c: Additional channel to search for packages. These are URLs searched in the order

You can use Object for storing any type of value for e.g. int, float, String, class objects, or any other java objects, since it is the root of all the class. For e.g.

1. Declaring a class

   class Person {
   public int personId;
   public String personName;
   
   public int getPersonId() {
       return personId;
   }
   
   public void setPersonId(int personId) {
       this.personId = personId;
   }
   
   public String getPersonName() {
       return personName;
   }
   
   public void setPersonName(String personName) {
       this.personName = personName;
   }}
   

2. main function code, which creates the new person object, int, float, and string type, and then is added to the List, and iterated using for loop. Each object is identified, and then the value is printed.

       Person p = new Person();
   p.setPersonId(1);
   p.setPersonName("Tom");
   
   List<Object> lstObject = new ArrayList<Object>();
   lstObject.add(1232);
   lstObject.add("String");
   lstObject.add(122.212f);
   lstObject.add(p);
   
   for (Object obj : lstObject) {
       if (obj.getClass() == String.class) {
           System.out.println("I found a string :- " + obj);
       }
       if (obj.getClass() == Integer.class) {
           System.out.println("I found an int :- " + obj);
       }
       if (obj.getClass() == Float.class) {
           System.out.println("I found a float :- " + obj);
       }
       if (obj.getClass() == Person.class) {
           Person person = (Person) obj;
           System.out.println("I found a person object");
           System.out.println("Person Id :- " + person.getPersonId());
           System.out.println("Person Name :- " + person.getPersonName());
       }
   }

Local variables don't have a default value.

They have to be definitely assigned before you use them. It reduces the chance of using a variable you think you've given a sensible value to, when actually it's got some default value.

This is just fine but if you add option which is not in optgroup it gets buggy.

<select>_x000D_
  <optgroup label="Level One">_x000D_
    <option> A.1 </option>_x000D_
    <optgroup label="&nbsp;&nbsp;&nbsp;&nbsp;Level Two">_x000D_
      <option>&nbsp;&nbsp;&nbsp;&nbsp; A.B.1 </option>_x000D_
    </optgroup>_x000D_
    <option> A.2 </option>_x000D_
  </optgroup>_x000D_
  <option> A </option>_x000D_
</select>

Would be much better if you used css and close optgroup right away :

<select>_x000D_
  <optgroup label="Level One"></optgroup>_x000D_
  <option style="padding-left:15px"> A.1 </option>_x000D_
  <optgroup label="Level Two" style="padding-left:15px"></optgroup>_x000D_
  <option style="padding-left:30px"> A.B.1 </option>_x000D_
  <option style="padding-left:15px"> A.2 </option>_x000D_
  <option> A </option>_x000D_
</select>

Rails 3.0.9

select options_for_select([value1, value2, value3], default)

This is my aproximation:

  Declare 
  Variableclob Clob;
  Temp_Save Varchar2(32767); //whether it is greater than 4000

  Begin
  Select reportClob Into Temp_Save From Reporte Where Id=...;
  Variableclob:=To_Clob(Temp_Save);
  Dbms_Output.Put_Line(Variableclob);


  End;

Git 1.8.2 features a new option ,--remote, that will enable exactly this behavior. Running

git submodule update --rebase --remote

will fetch the latest changes from upstream in each submodule, rebase them, and check out the latest revision of the submodule. As the documentation puts it:

--remote

This option is only valid for the update command. Instead of using the superproject’s recorded SHA-1 to update the submodule, use the status of the submodule’s remote-tracking branch.

This is equivalent to running git pull in each submodule, which is generally exactly what you want.

(This was copied from this answer.)

MD5 processes an arbitrary-length message into a fixed-length output of 128 bits, typically represented as a sequence of 32 hexadecimal digits.

Locale-dependent version: In some environments, the following will extract the day name from the date:

set dayname=%date:~0,3%

It assumes that the day name is the first part of %date%. Depending on the machine settings, though, the substring part (~0,3) would need to change.

A statement such as this would dump to a file with a three character day name:

set logfile=%date:~0,3%.log
echo some stuff > %logfile%

Locale-independent version: If you need it less dependent on the current machine's day format, another way of doing it would be to write a tiny application that prints the day of the week. Then use the output of that program from the batch file. For example, the following C application prints dayN where N=0..6.

#include <stdio.h>
#include <time.h>

int main( int argc, char* argv[] )
{
   time_t curtime;
   struct tm * tmval;

   time( &curtime );
   tmval = localtime( &curtime );
   // print dayN.  Or use a switch statement and print
   // the actual day name if you want
   printf( "day%d", tmval->tm_wday );
}

If the above were compiled and linked as myday.exe, then you could use it from a batch file like this:

for /f %%d in ('myday.exe') do set logfile=%%d.log
echo some stuff > %logfile%

Either add an event listener, or have the image announce itself with onload. Then figure out the dimensions from there.

<img id="photo"
     onload='loaded(this.id)'
     src="a_really_big_file.jpg"
     alt="this is some alt text"
     title="this is some title text" />

I tried lots of different solutions, the only one that worked for me was based on the solution by Chris G on this page (but with a slight modification).

I have turned it into a jQuery plugin for future use for anyone that needs it

(function($){
    $.fn.setCursorToTextEnd = function() {
        var $initialVal = this.val();
        this.val($initialVal);
    };
})(jQuery);

example of usage:

$('#myTextbox').setCursorToTextEnd();

You don't really need to have parenthesis. You can sort directly:

SELECT *, 1 AS RN FROM TABLE_A
UNION ALL 
SELECT *, 2 AS RN FROM TABLE_B
ORDER BY RN, COLUMN_1

ls -R -L

-L dereferences symbolic links. This will also make it impossible to see any symlinks to files, though - they'll look like the pointed-to file.

As above mentioned, there is no special command to do it. However, if all those connection are inactive, using 'flush tables;' is able to release all those connection which are not active.

You may try this:-

Scanner scan = new Scanner(System.in);
System.out.println("Type a sentence and press enter.");
String input = scan.nextLine();
String strippedInput = input.replaceAll("\\W", "");
System.out.println("Your string: " + strippedInput);

[^\w] matches a non-word character, so the above regular expression will match and remove all non-word characters.

The escape character in batch scripts is ^. But for double-quoted strings, double up the quotes:

"string with an embedded "" character"

I also Had to filter based on the URL pattern(/{servicename}/api/stats/)in java code .

if (path.startsWith("/{servicename}/api/statistics/")) {
validatingAuthToken(((HttpServletRequest) request).getHeader("auth_token"));
filterChain.doFilter(request, response);            
}

But its bizarre, that servlet doesn't support url pattern other than (/*), This should be a very common case for servlet API's !

I had the same error when accessing an already transactional-annotated method from a non-transactional method within the same component:

Before:
    @Component
    public class MarketObserver {
        @PersistenceContext(unitName = "maindb")
        private EntityManager em;

        @Transactional(value = "txMain", propagation = Propagation.REQUIRES_NEW)
        public void executeQuery() {
          em.persist(....);
        }


        @Async
        public void startObserving() {
          executeQuery(); //<-- Wrong
        }
    }

    //In another bean:
     marketObserver.startObserving();

I fixed the error by calling the executeQuery() on the self-referenced component:

Fixed version:
    @Component
    public class MarketObserver {
        @PersistenceContext(unitName = "maindb")
        private EntityManager em;

        @Autowired
        private GenericApplicationContext context;

        @Transactional(value = "txMain", propagation = Propagation.REQUIRES_NEW)
        public void executeQuery() {
          em.persist(....);
        }


        @Async
        public void startObserving() {
          context.getBean(MarketObserver.class).executeQuery(); //<-- Works
        }
    }

My answer refers to a special case of the general problem the OP describes, but I'll add it just in case it helps somebody out.

When using @EnableOAuth2Sso, Spring puts an OAuth2RestTemplate on the application context, and this component happens to assume thread-bound servlet-related stuff.

My code has a scheduled async method that uses an autowired RestTemplate. This isn't running inside DispatcherServlet, but Spring was injecting the OAuth2RestTemplate, which produced the error the OP describes.

The solution was to do name-based injection. In the Java config:

@Bean
public RestTemplate pingRestTemplate() {
    return new RestTemplate();
}

and in the class that uses it:

@Autowired
@Qualifier("pingRestTemplate")
private RestTemplate restTemplate;

Now Spring injects the intended, servlet-free RestTemplate.

$_SERVER["USER"]

$_SERVER["USERNAME"] 

Should the benchmark measure time/iteration or iterations/time, and why?

It depends on what you are trying to test.

If you are interested in latency, use time/iteration and if you are interested in throughput, use iterations/time.

        val queryParams = StringBuilder(uri.query.orEmpty())
        if (queryParams.isNotEmpty())
            queryParams.append('&')

        queryParams.append(URLEncoder.encode("$QUERY_PARAM=$param", Xml.Encoding.UTF_8.name))
        return URI(uri.scheme, uri.authority, uri.path, queryParams.toString(), uri.fragment).toString()

I found a real cool Grid which I also use for columns. Check it out Simple Grid. Wich this CSS you can simply use:

<div class="grid">
    <div class="col-1-2">
       <div class="content">
           <p>...insert content left side...</p>
       </div>
    </div>
    <div class="col-1-2">
       <div class="content">
           <p>...insert content right side...</p>
       </div>
    </div>
</div>

I use it for all my projects.

Because it's a Deployment, Kubernetes will automatically recreate the pod and pull the latest image.

If you are facing this issue in Mac-OSX terminal with python, try updating the versions of the packages you are using. So, go to your files in python and where you specified the packages, update them to the latest versions available on the internet.

\l - Display database
\c - Connect to database
\dn - List schemas
\dt - List tables inside public schemas
\dt schema1. - List tables inside particular schemas. For eg: 'schema1'.

Use filectime. For Windows it will return the creation time, and for Unix the change time which is the best you can get because on Unix there is no creation time (in most filesystems).

Note also that in some Unix texts the ctime of a file is referred to as being the creation time of the file. This is wrong. There is no creation time for Unix files in most Unix filesystems.

Indexing a list is done using double bracket, i.e. hypo_list[[1]] (e.g. have a look here: http://www.r-tutor.com/r-introduction/list). BTW: read.table does not return a table but a dataframe (see value section in ?read.table). So you will have a list of dataframes, rather than a list of table objects. The principal mechanism is identical for tables and dataframes though.

Note: In R, the index for the first entry is a 1 (not 0 like in some other languages).

Dataframes

l <- list(anscombe, iris)   # put dfs in list
l[[1]]             # returns anscombe dataframe

anscombe[1:2, 2]   # access first two rows and second column of dataset
[1] 10  8

l[[1]][1:2, 2]     # the same but selecting the dataframe from the list first
[1] 10  8

Table objects

tbl1 <- table(sample(1:5, 50, rep=T))
tbl2 <- table(sample(1:5, 50, rep=T))
l <- list(tbl1, tbl2)  # put tables in a list

tbl1[1:2]              # access first two elements of table 1 

Now with the list

l[[1]]                 # access first table from the list

1  2  3  4  5 
9 11 12  9  9 

l[[1]][1:2]            # access first two elements in first table

1  2 
9 11 

there is an even simpler way of emulating a switch structure that uses instanceof, you do this by creating a code block in your method and naming it with a label. Then you use if structures to emulate the case statements. If a case is true then you use the break LABEL_NAME to get out of your makeshift switch structure.

        DEFINE_TYPE:
        {
            if (a instanceof x){
                //do something
                break DEFINE_TYPE;
            }
            if (a instanceof y){
               //do something
                break DEFINE_TYPE;
            }
            if (a instanceof z){
                // do something
                break DEFINE_TYPE;
            }
        }

UPDATE `salary_generation_tbl` SET
    `modified_by` = IF(
        LOCATE('$', `other_salary_string`) > 0,
        SUBSTRING(`other_salary_string`, 1, LOCATE('$', `other_salary_string`) - 1),
        `other_salary_string`
    ),
    `other_salary` = IF(
        LOCATE('$', `other_salary_string`) > 0,
        SUBSTRING(`other_salary_string`, LOCATE('$', `other_salary_string`) + 1),
        NULL
    );

If the cube is directly inside the container:

If cube is next to (after containers closing tag) the container:

#container:hover + #cube { background-color: yellow; }

If the cube is somewhere inside the container:

You could use ArraySegment<T>. It's very light-weight as it doesn't copy the array:

string[] a = { "one", "two", "three", "four", "five" };
var segment = new ArraySegment<string>( a, 1, 2 );

jQuery dialog has an isOpen property that can be used to check if a jQuery dialog is open or not.

You push your local repository to the remote repository using the git push command after first establishing a relationship between the two with the git remote add [alias] [url] command. If you visit your Github repository, it will show you the URL to use for pushing. You'll first enter something like:

git remote add origin [email protected]:username/reponame.git

Unless you started by running git clone against the remote repository, in which case this step has been done for you already.

And after that, you'll type:

git push origin master

After your first push, you can simply type:

git push

when you want to update the remote repository in the future.

For those of us trying to figure out how to hash our own classes whilst still using the standard template, there is a simple solution:

1. In your class you need to define an equality operator overload ==. If you don't know how to do this, GeeksforGeeks has a great tutorial https://www.geeksforgeeks.org/operator-overloading-c/

2. Under the standard namespace, declare a template struct called hash with your classname as the type (see below). I found a great blogpost that also shows an example of calculating hashes using XOR and bitshifting, but that's outside the scope of this question, but it also includes detailed instructions on how to accomplish using hash functions as well https://prateekvjoshi.com/2014/06/05/using-hash-function-in-c-for-user-defined-classes/

namespace std {

  template<>
  struct hash<my_type> {
    size_t operator()(const my_type& k) {
      // Do your hash function here
      ...
    }
  };

}

3. So then to implement a hashtable using your new hash function, you just have to create a std::map or std::unordered_map just like you would normally do and use my_type as the key, the standard library will automatically use the hash function you defined before (in step 2) to hash your keys.

#include <unordered_map>

int main() {
  std::unordered_map<my_type, other_type> my_map;
}

Starting with SQL Server 2012, you could use TRY_PARSE or TRY_CONVERT.

SELECT TRY_PARSE(MyVarcharCol as int)

SELECT TRY_CONVERT(int, MyVarcharCol)

I think you may have installed the version of mongodb for the wrong system distro.

Take a look at how to install mongodb for ubuntu and debian:

http://docs.mongodb.org/manual/tutorial/install-mongodb-on-debian/ http://docs.mongodb.org/manual/tutorial/install-mongodb-on-ubuntu/

I had a similar problem, and what happened was that I was installing the ubuntu packages in debian

If you're using pure JS you can simply do it like:

var input = document.getElementById('myInput');

if(input.value.length == 0)
    input.value = "Empty";

Here's a demo: http://jsfiddle.net/nYtm8/

Try:

$(document).ready(function(){
   $('a .sign_new').click(function(){
      alert('Sign new href executed.'); 
   }); 
});

You've mixed up the class and href names / selector type.

You can do injection on Directives, and it looks just like it does everywhere else.

app.directive('changeIt', ['myData', function(myData){
    return {
        restrict: 'C',
        link: function (scope, element, attrs) {
            scope.name = myData.name;
        }
    }
 }]);

To add to Preston's answer, here's the complete list of the HttpContent derived classes available in the standard library:

Credit: https://pfelix.wordpress.com/2012/01/16/the-new-system-net-http-classes-message-content/

There's also a supposed ObjectContent but I was unable to find it in ASP.NET Core.

Of course, you could skip the whole HttpContent thing all together with Microsoft.AspNet.WebApi.Client extensions (you'll have to do an import to get it to work in ASP.NET Core for now: https://github.com/aspnet/Home/issues/1558) and then you can do things like:

var response = await client.PostAsJsonAsync("AddNewArticle", new Article
{
    Title = "New Article Title",
    Body = "New Article Body"
});

Such a fun problem.
The rationale of the probability of a point being chosen lowering as distance from the axis origin increases is explained multiple times above. We account for that by taking the root of U[0,1]. Here's a general solution for a positive r in Python 3.

import numpy
import math
import matplotlib.pyplot as plt

def sq_point_in_circle(r):
    """
    Generate a random point in an r radius circle 
    centered around the start of the axis
    """

    t = 2*math.pi*numpy.random.uniform()
    R = (numpy.random.uniform(0,1) ** 0.5) * r

    return(R*math.cos(t), R*math.sin(t))

R = 200 # Radius
N = 1000 # Samples

points = numpy.array([sq_point_in_circle(R) for i in range(N)])
plt.scatter(points[:, 0], points[:,1])

Html.Hidden('name', 'value') creates a hidden tag with name = 'name' and value = 'value'.

Html.HiddenFor(x => x.nameProp) creates a hidden tag with a name = 'nameProp' and value = x.nameProp.

At face value these appear to do similar things, with one just more convenient than the other. But its actual value is for model binding. When MVC tries to associate the html to the model, it needs to have the name of the property, and for Html.Hidden, we chose 'name', and not 'nameProp', and thus the binding wouldn't work. You'd have to have a custom binding object, or get the values from the form data. If you are redisplaying the page, you'd have to set the model to the values again.

So you can use Html.Hidden, but if you get the name wrong, or if you change the property name in the model, the auto binding will fail when you submit the form. But by using a type checked expression, you'll get code completion, and when you change the property name, you will get a compile time error. And then you are guaranteed to have the correct name in the form.

One of the better features of MVC.

By default, NPM simply installs a package under node_modules. When you're trying to install dependencies for your app/module, you would need to first install them, and then add them to the dependencies section of your package.json.

--save-dev adds the third-party package to the package's development dependencies. It won't be installed when someone runs npm install directly to install your package. It's typically only installed if someone clones your source repository first and then runs npm install in it.

--save adds the third-party package to the package's dependencies. It will be installed together with the package whenever someone runs npm install package.

Dev dependencies are those dependencies that are only needed for developing the package. That can include test runners, compilers, packagers, etc. Both types of dependencies are stored in the package's package.json file. --save adds to dependencies, --save-dev adds to devDependencies

npm install documentation can be referred here.

--

Please note that --save is now the default option, since NPM 5. Therefore, it is not explicitly needed anymore. It is possible to run npm install without the --save to achieve the same result.

for i=1,#target do
    game.Players.target[i].Character:BreakJoints()
end

Is incorrect, if "target" contains "FakeNameHereSoNoStalkers" then the run code would be:

game.Players.target.1.Character:BreakJoints()

Which is completely incorrect.

c = game.Players:GetChildren()

Never use "Players:GetChildren()", it is not guaranteed to return only players.

Instead use:

c = Game.Players:GetPlayers()

if msg:lower()=="me" then
    table.insert(people, source)
    return people

Here you add the player's name in the list "people", where you in the other places adds the player object.

Fixed code:

local Admins = {"FakeNameHereSoNoStalkers"}

function Kill(Players)
    for i,Player in ipairs(Players) do
        if Player.Character then
            Player.Character:BreakJoints()
        end
    end
end

function IsAdmin(Player)
    for i,AdminName in ipairs(Admins) do
        if Player.Name:lower() == AdminName:lower() then return true end
    end
    return false
end

function GetPlayers(Player,Msg)
    local Targets = {}
    local Players = Game.Players:GetPlayers()

    if Msg:lower() == "me" then
        Targets = { Player }
    elseif Msg:lower() == "all" then
        Targets = Players
    elseif Msg:lower() == "others" then
        for i,Plr in ipairs(Players) do
            if Plr ~= Player then
                table.insert(Targets,Plr)
            end
        end
    else
        for i,Plr in ipairs(Players) do
            if Plr.Name:lower():sub(1,Msg:len()) == Msg then
                table.insert(Targets,Plr)
            end
        end
    end
    return Targets
end

Game.Players.PlayerAdded:connect(function(Player)
    if IsAdmin(Player) then
        Player.Chatted:connect(function(Msg)
            if Msg:lower():sub(1,6) == ":kill " then
                Kill(GetPlayers(Player,Msg:sub(7)))

[^,]*$

might do. (Matches everything after the last comma).

Explanation: [^,] matches every character except for ,. The * denotes that the regexp matches any number of repetition of [^,]. The $ sign matches the end of the line.

I'm not 100% sure what your sample code is supposed to do, but the following snippet should help you 'call the contacts list function, pick a contact, then return to [your] app with the contact's name'.

There are three steps to this process.

1. Permissions

Add a permission to read contacts data to your application manifest.

<uses-permission android:name="android.permission.READ_CONTACTS"/>

2. Calling the Contact Picker

Within your Activity, create an Intent that asks the system to find an Activity that can perform a PICK action from the items in the Contacts URI.

Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);

Call startActivityForResult, passing in this Intent (and a request code integer, PICK_CONTACT in this example). This will cause Android to launch an Activity that's registered to support ACTION_PICK on the People.CONTENT_URI, then return to this Activity when the selection is made (or canceled).

startActivityForResult(intent, PICK_CONTACT);

3. Listening for the Result

Also in your Activity, override the onActivityResult method to listen for the return from the 'select a contact' Activity you launched in step 2. You should check that the returned request code matches the value you're expecting, and that the result code is RESULT_OK.

You can get the URI of the selected contact by calling getData() on the data Intent parameter. To get the name of the selected contact you need to use that URI to create a new query and extract the name from the returned cursor.

@Override
public void onActivityResult(int reqCode, int resultCode, Intent data) {
  super.onActivityResult(reqCode, resultCode, data);

  switch (reqCode) {
    case (PICK_CONTACT) :
      if (resultCode == Activity.RESULT_OK) {
        Uri contactData = data.getData();
        Cursor c =  getContentResolver().query(contactData, null, null, null, null);
        if (c.moveToFirst()) {
          String name = c.getString(c.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
          // TODO Whatever you want to do with the selected contact name.
        }
      }
      break;
  }
}

Also create PATH enviroment variable on you computer like this (if it doesn't exist already):

1. Right click on My Computer/Computer
2. Properties
3. Advanced system settings (or just Advanced)
4. Enviroment variables
5. If PATH variable doesn't exist among "User variables" click New (Variable name: PATH, Variable value : C:\Program Files\Java\jdk1.8.0\bin; <-- please check out the right version, this may differ as Oracle keeps updating Java). ; in the end enables assignment of multiple values to PATH variable.
6. Click OK! Done

To be sure that everything works, open CMD Prompt and type: java -version to check for Java version and javac to be sure that compiler responds.

I hope this helps. Good luck!

I was getting that exact message whenever my requests took more than 2 minutes to finish. The browser would disconnect from the request, but the request on the backend continued until it was finished. The server (ASP.NET Web API in my case) wouldn't detect the disconnect.

After an entire day searching, I finally found this answer, explaining that if you use the proxy config, it has a default timeout of 120 seconds (or 2 minutes).

So, you can edit your proxy configuration and set it to whatever you need:

{
  "/api": {
    "target": "http://localhost:3000",
    "secure": false,
    "timeout": 6000000
  }
}

Now, I was using agentkeepalive to make it work with NTLM authentication, and didn't know that the agent's timeout has nothing to do with the proxy's timeout, so both have to be set. It took me a while to realize that, so here's an example:

const Agent = require('agentkeepalive');

module.exports = {
    '/api/': {
        target: 'http://localhost:3000',
        secure: false,
        timeout: 6000000,          // <-- this is needed as well
        agent: new Agent({
            maxSockets: 100,
            keepAlive: true,
            maxFreeSockets: 10,
            keepAliveMsecs: 100000,
            timeout: 6000000,      // <-- this is for the agentkeepalive
            freeSocketTimeout: 90000
        }),
        onProxyRes: proxyRes => {
            let key = 'www-authenticate';
            proxyRes.headers[key] = proxyRes.headers[key] &&
                proxyRes.headers[key].split(',');
        }
    }
};

I agree that a data structure like a List is the best way to go:

List<Integer> values = new ArrayList<Integer>();
Scanner in = new Scanner(System.in);
int value;
int numValues = 0;
do {
    value = in.nextInt();
    values.add(value);
} while (value >= 1) && (value <= 100);

Or you can just allocate an array of a max size and load values into it:

int maxValues = 100;
int [] values = new int[maxValues];
Scanner in = new Scanner(System.in);
int value;
int numValues = 0;
do {
    value = in.nextInt();
    values[numValues++] = value;
} while (value >= 1) && (value <= 100) && (numValues < maxValues);

something like

  position:relative;
  top:-5px;

just on the inline element itself works for me. Have to play with the top to get it centered vertically...

MongoDB gives freedom to be schema-less and this feature can result in pain in the long term if not thought or planned well,

There are 2 options either Embed or Reference. I will not go through definitions as the above answers have well defined them.

When embedding you should answer one question is your embedded document going to grow, if yes then how much (remember there is a limit of 16 MB per document) So if you have something like a comment on a post, what is the limit of comment count, if that post goes viral and people start adding comments. In such cases, reference could be a better option (but even reference can grow and reach 16 MB limit).

So how to balance it, the answer is a combination of different patterns, check these links, and create your own mix and match based on your use case.

My situation was a little different. The solution was to strip the .pem from everything outside of the CERTIFICATE and PRIVATE KEY sections and to invert the order which they appeared. After converting from pfx to pem file, the certificate looked like this:

Bag Attributes
localKeyID: ...
issuer=...
-----BEGIN CERTIFICATE-----
...
-----END CERTIFICATE-----
Bag Attributes
more garbage...
-----BEGIN PRIVATE KEY-----
...
-----END PRIVATE KEY-----

After correcting the file, it was just:

-----BEGIN PRIVATE KEY-----
...
-----END PRIVATE KEY-----
-----BEGIN CERTIFICATE-----
...
-----END CERTIFICATE-----

It is a static function on the MessageBox class, the simple way to do this is using

MessageBox.Show("my message");

in the System.Windows.Forms class. You can find more on the msdn page for this here . Among other things you can control the message box text, title, default button, and icons. Since you didn't specify, if you are trying to do this in a webpage you should look at triggering the javascript alert("my message"); or confirm("my question"); functions.

Run this in project folder:

$ git log --pretty=format:"%C(yellow)%h %ar %C(auto)%d %Creset %s , %Cblue%cn" --graph --all

And if you like, add this line to your ~/.gitconfig:

[alias]
    ...
    list = log --pretty=format:\"%C(yellow)%h %ar %C(auto)%d %Creset %s, %Cblue%cn\" --graph --all

You can pass GetDate() function as an parameter to your insert query e.g

Insert into table (col1,CreatedOn) values (value1,Getdate())

This is an example to read and write binary jjpg or wmv video file. FILE *fout; FILE *fin;

         exit(1);
      }

 fout=fopen("D:\\ newpic.jpg","wb");
 ch=fgetc(fin);
       while (ch!=EOF)
             { 
                  s=(char *)ch;
                  printf("%c",s);
                 ch=fgetc (fin):
                 fputc(s,fout);
                 s++;
              }

        printf("data read and copied");
        fclose(fin);
        fclose(fout);

Use an abstract class if you want to provide some basic implementations.

Here's an abstraction of Will Nathan's answer if anyone just wants an easy copy-paste add-in function:

function find (name, query, cb) {
    mongoose.connection.db.collection(name, function (err, collection) {
       collection.find(query).toArray(cb);
   });
}

simply do find(collection_name, query, callback); to be given the result.

for example, if I have a document { a : 1 } in a collection 'foo' and I want to list its properties, I do this:

find('foo', {a : 1}, function (err, docs) {
            console.dir(docs);
        });
//output: [ { _id: 4e22118fb83406f66a159da5, a: 1 } ]

No siblings solution:

var x = $('#xxx').parent().html();

Universal solution:

// no cloning necessary    
var x = $('#xxx').wrapAll('<div>').parent().html(); 
alert(x);

Using .insertAdjacentHTML() preserves event listeners, and is supported by all major browsers. It's a simple one-line replacement for .innerHTML.

var html_to_insert = "<p>New paragraph</p>";

// with .innerHTML, destroys event listeners
document.getElementById('mydiv').innerHTML += html_to_insert;

// with .insertAdjacentHTML, preserves event listeners
document.getElementById('mydiv').insertAdjacentHTML('beforeend', html_to_insert);

The 'beforeend' argument specifies where in the element to insert the HTML content. Options are 'beforebegin', 'afterbegin', 'beforeend', and 'afterend'. Their corresponding locations are:

<!-- beforebegin -->
<div id="mydiv">
  <!-- afterbegin -->
  <p>Existing content in #mydiv</p>
  <!-- beforeend -->
</div>
<!-- afterend -->

You can test this VB Script from command prompt:

>> cscript.exe RunExcel.VBS

Once you have the VB Script file and workbook tested so that it does what you want, you can then use Microsoft Task Scheduler (Control Panel-> Administrative Tools--> Task Scheduler) to execute ‘cscript.exe RunExcel.vbs’ automatically for you.

Please note the path of the macro should be in correct format and inside single quotes like:

strMacroName = "'" & strPath & "\YourWorkBook.xlsm'" & 
"!ModuleName.MacroName"

There are several rules ( applied in this order ) :

1. inline css ( html style attribute ) overrides css rules in style tag and css file
2. a more specific selector takes precedence over a less specific one
3. rules that appear later in the code override earlier rules if both have the same specificity.
4. A css rule with !important always takes precedence.

In your case its rule 3 that applies.

Specificity for single selectors from highest to lowest:

• ids (example: #main selects <div id="main">)
• classes (ex.: .myclass), attribute selectors (ex.: [href=^https:]) and pseudo-classes (ex.: :hover)
• elements (ex.: div) and pseudo-elements (ex.: ::before)

To compare the specificity of two combined selectors, compare the number of occurences of single selectors of each of the specificity groups above.

Example: compare #nav ul li a:hover to #nav ul li.active a::after

• count the number of id selectors: there is one for each (#nav)
• count the number of class selectors: there is one for each (:hover and .active)
• count the number of element selectors: there are 3 (ul li a) for the first and 4 for the second (ul li a ::after), thus the second combined selector is more specific.

A good article about css selector specificity.

Just need to get the element and use the method setCustomValidity.

Example

var foo = document.getElementById('foo');
foo.setCustomValidity(' An error occurred');

For those who rooted the Android device with Magisk, you can install adb_root from https://github.com/evdenis/adb_root. Then adb root can run smoothly.

Detect if a target attribute was used and contains "_blank". For mobile devices that don't like "_blank", this is a reliable alternative.

    $('.someSelector').bind('touchend click', function() {

        var url = $('a', this).prop('href');
        var target = $('a', this).prop('target');

        if(url) {
            // # open in new window if "_blank" used
            if(target == '_blank') { 
                window.open(url, target);
            } else {
                window.location = url;
            }
        }           
    });

If you need to initialize an array fast, you might do it by blocks instead of with a generator initializer, and it's going to be much faster. Creating a list by [0]*count is just as fast, still.

import array

def zerofill(arr, count):
    count *= arr.itemsize
    blocksize = 1024
    blocks, rest = divmod(count, blocksize)
    for _ in xrange(blocks):
        arr.fromstring("\x00"*blocksize)
    arr.fromstring("\x00"*rest)

def test_zerofill(count):
    iarr = array.array('i')
    zerofill(iarr, count)
    assert len(iarr) == count

def test_generator(count):
    iarr = array.array('i', (0 for _ in xrange(count)))
    assert len(iarr) == count

def test_list(count):
    L = [0]*count
    assert len(L) == count

if __name__ == '__main__':
    import timeit
    c = 100000
    n = 10
    print timeit.Timer("test(c)", "from __main__ import c, test_zerofill as test").repeat(number=n)
    print timeit.Timer("test(c)", "from __main__ import c, test_generator as test").repeat(number=n)
    print timeit.Timer("test(c)", "from __main__ import c, test_list as test").repeat(number=n)

Results:

(array in blocks) [0.022809982299804688, 0.014942169189453125, 0.014089107513427734]

Got it solved. I missed to delete the egg_info files of all previous Django versions. Removed them from /usr/local/lib/python2.7/dist-packages. Also from /usr/lib/python2.7/dist-packages (if any present here)

sudo pip freeze| grep Django
sudo pip show -f Django
sudo pip search Django | more +/^Django

All above commands should not show Django version to verify clean uninstallation.

Here is a link from developer.nokia.com wiki pages, which explains how to install Windows Phone 8 SDK on a Virtual Machine with Working Emulator

And another link here

AFAIK, it is not possible to directly install WP8 SDK in Windows 7, because WP8 sdk is VS 2012 supported and also its emulator works on a Hyper-V (which is integrated into the Windows 8).

The best way to work with args for your winforms app is to use

string[] args = Environment.GetCommandLineArgs();

You can probably couple this with the use of an enum to solidify the use of the array througout your code base.

"And you can use this anywhere in your application, you aren’t just restricted to using it in the main() method like in a console application."

Found at:HERE

This problem arises due to incompatible JDK version. Download and install latest JDK(currently its 8) from java official site in case you are using previous versions. Then in Android Studio go to File->Project Structure->SDK location -> JDK location and set it to 'C:\Program Files\Java\jdk1.8.0_121' (Default location of JDK). Gradle sync your project and you are all set...

Its seems that server is not running properly so ensure that with terminal by

telnet ip port

example

telnet localhost 8069

It will return connected to localhost so it indicates that there is no problem with the connection Else it will return Connection refused it indicates that there is problem with the connection

I felt like replying as well, explaining the same thing as the others a bit differently. I am sure you know most of this, but it might help someone else.

<a href="#" class="view">

The

href="#"

part is a commonly used way to make sure the link doesn't lead anywhere on it's own. the #-attribute is used to create a link to some other section in the same document. For example clicking a link of this kind:

<a href="#news">Go to news</a>

will take you to wherever you have the

<a name="news"></a>

code. So if you specify # without any name like in your case, the link leads nowhere.

The

class="view"

part gives it an identifier that CSS or javascript can use. Inside the CSS-files (if you have any) you will find specific styling procedures on all the elements tagged with the "view"-class.

To find out where the URL is specified I would look in the javascript code. It is either written directly in the same document or included from another file.

Search your source code for something like:

<script type="text/javascript"> bla bla bla </script>

or

<script> bla bla bla </script>

and then search for any reference to your "view"-class. An included javascript file can look something like this:

<script type="text/javascript" src="include/javascript.js"></script>

In that case, open javascript.js under the "include" folder and search in that file. Most commonly the includes are placed between <head> and </head> or close to the </body>-tag.

A faster way to find the link is to search for the actual link it goes to. For example, if you are directed to http://www.google.com/search?q=html when you click it, search for "google.com" or something in all the files you have in your web project, just remember the included files.

In many text editors you can open all the files at once, and then search in them all for something.

The reset_index() is a pandas DataFrame method that will transfer index values into the DataFrame as columns. The default setting for the parameter is drop=False (which will keep the index values as columns).

All you have to do add .reset_index(inplace=True) after the name of the DataFrame:

df.reset_index(inplace=True)  

in visual studio 2012 you can simply select the browser you want to debug with from the dropdown box placed just over the code editor

PyQt5:

from PyQt5.QtWidgets import QApplication
from PyQt5 import QtGui
from PyQt5.QtGui import QClipboard
import sys


def main():


    app=QApplication(sys.argv)
    cb = QApplication.clipboard()
    cb.clear(mode=cb.Clipboard )
    cb.setText("Copy to ClipBoard", mode=cb.Clipboard)
    sys.exit(app.exec_())

if __name__ == "__main__":
    main()

toString is a function, not a property. You'll want this:

console.log(aa.toString());

Alternatively, use join to specify the separator (toString() === join(','))

console.log(aa.join(' and '));

I prefer this:

class CoolAdmin(admin.ModelAdmin):
    list_display = ('pk', 'submodel__field')

    @staticmethod
    def submodel__field(obj):
        return obj.submodel.field

xmlns:android="http://schemas.android.com/apk/res/android" 

xmlns : is xml name space and the URL : "http://schemas.android.com/apk/res/android" is nothing but

XSD which is [XML schema definition] : which is used define rules for XML file .

Example :

<LinearLayout 
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" 
android:layout_width="match_parent"
android:layout_height="match_parent">

<EditText
   android:layout_width="match_parent"
   android:layout_height="wrap_content"
   android:layout_marginBottom="4dp"
   android:hint="User Name"
  />
</LinearLayout> 

Let me explain What Kind of Rules ? .

1. In above XML file we already define layout_width for our layout now IF you will define same attribute second time you will get an error .
2. EditText is there but if you want add another EditText no problem .

Such Kind of Rules are define in XML XSD : "http://schemas.android.com/apk/res/android"

little bit late but I hope this helps you .

Here's a more concrete example of how to access GET parameters. The Request object has a method that parses them out for you called Query:

Assuming a request URL like http://host:port/something?param1=b

func newHandler(w http.ResponseWriter, r *http.Request) {
  fmt.Println("GET params were:", r.URL.Query())

  // if only one expected
  param1 := r.URL.Query().Get("param1")
  if param1 != "" {
    // ... process it, will be the first (only) if multiple were given
    // note: if they pass in like ?param1=&param2= param1 will also be "" :|
  }

  // if multiples possible, or to process empty values like param1 in
  // ?param1=&param2=something
  param1s := r.URL.Query()["param1"]
  if len(param1s) > 0 {
    // ... process them ... or you could just iterate over them without a check
    // this way you can also tell if they passed in the parameter as the empty string
    // it will be an element of the array that is the empty string
  }    
}

Also note "the keys in a Values map [i.e. Query() return value] are case-sensitive."

For #4, the closest thing to starting java with a jar file for your app is a new feature in Python 2.6, executable zip files and directories.

python myapp.zip

Where myapp.zip is a zip containing a __main__.py file which is executed as the script file to be executed. Your package dependencies can also be included in the file:

__main__.py
mypackage/__init__.py
mypackage/someliblibfile.py

You can also execute an egg, but the incantation is not as nice:

# Bourn Shell and derivatives (Linux/OSX/Unix)
PYTHONPATH=myapp.egg python -m myapp

rem Windows 
set PYTHONPATH=myapp.egg
python -m myapp

This puts the myapp.egg on the Python path and uses the -m argument to run a module. Your myapp.egg will likely look something like:

myapp/__init__.py
myapp/somelibfile.py

And python will run __init__.py (you should check that __file__=='__main__' in your app for command line use).

Egg files are just zip files so you might be able to add __main__.py to your egg with a zip tool and make it executable in python 2.6 and run it like python myapp.egg instead of the above incantation where the PYTHONPATH environment variable is set.

More information on executable zip files including how to make them directly executable with a shebang can be found on Michael Foord's blog post on the subject.

Linting is the process of running a program that will analyse code for potential errors.

See lint on wikipedia:

lint was the name originally given to a particular program that flagged some suspicious and non-portable constructs (likely to be bugs) in C language source code. The term is now applied generically to tools that flag suspicious usage in software written in any computer language.

Since there are many different kinds of casting each with different semantics, static_cast<> allows you to say "I'm doing a legal conversion from one type to another" like from int to double. A plain C-style cast can mean a lot of things. Are you up/down casting? Are you reinterpreting a pointer?

edittext.requestFocus() works for me in my Activity and Fragment

You should override the inspect method of your object to return the desired hash, or just implement a similar method without overriding the default object behaviour.

If you want to get fancier, you can iterate over an object's instance variables with object.instance_variables

You can just create a shortcut and then right click on it -> properties -> change icon, and just browse for your desired icon. Hope this help.

To set an icon of a shortcut programmatically, see this article using SetIconLocation:

How Can I Change the Icon for an Existing Shortcut?:

https://devblogs.microsoft.com/scripting/how-can-i-change-the-icon-for-an-existing-shortcut/

Const DESKTOP = &H10&
Set objShell = CreateObject("Shell.Application")
Set objFolder = objShell.NameSpace(DESKTOP)
Set objFolderItem = objFolder.ParseName("Test Shortcut.lnk")
Set objShortcut = objFolderItem.GetLink
objShortcut.SetIconLocation "C:\Windows\System32\SHELL32.dll", 13
objShortcut.Save

For completeness I'll mention that Powershell 3.0 now has a -Tail flag on Get-Content

Get-Content ./log.log -Tail 10

gets the last 10 lines of the file

Get-Content ./log.log -Wait -Tail 10

gets the last 10 lines of the file and waits for more

Also, for those *nix users, note that most systems alias cat to Get-Content, so this usually works

cat ./log.log -Tail 10

You can use Javascript to get the viewport width and height. Then pass the values back via a hidden form input or ajax.

At its simplest

var width = $(window).width();
var height = $(window).height();

Complete method using hidden form inputs

Assuming you have: JQuery framework.

First, add these hidden form inputs to store the width and height until postback.

<asp:HiddenField ID="width" runat="server" />
<asp:HiddenField ID="height" runat="server" />

Next we want to get the window (viewport) width and height. JQuery has two methods for this, aptly named width() and height().

Add the following code to your .aspx file within the head element.

<script type="text/javascript">
$(document).ready(function() {

    $("#width").val() = $(window).width();
    $("#height").val() = $(window).height();    

});
</script>

Result

This will result in the width and height of the browser window being available on postback. Just access the hidden form inputs like this:

var TheBrowserWidth = width.Value;
var TheBrowserHeight = height.Value;

This method provides the height and width upon postback, but not on the intial page load.

Note on UpdatePanels: If you are posting back via UpdatePanels, I believe the hidden inputs need to be within the UpdatePanel.

Alternatively you can post back the values via an ajax call. This is useful if you want to react to window resizing.

Update for jquery 3.1.1

I had to change the JavaScript to:

$("#width").val($(window).width());
$("#height").val($(window).height());

You should pass a pointer if you are going to modify the value of the variable. Even though technically passing a reference or a pointer are the same, passing a pointer in your use case is more readable as it "advertises" the fact that the value will be changed by the function.

The way I do it is pass the host IP as environment variable to container. Container then access the host by that variable.

Use different format or pattern to get the information from the date

var myDate = new Date("2015-06-17 14:24:36");_x000D_
console.log(moment(myDate).format("YYYY-MM-DD HH:mm:ss"));_x000D_
console.log("Date: "+moment(myDate).format("YYYY-MM-DD"));_x000D_
console.log("Year: "+moment(myDate).format("YYYY"));_x000D_
console.log("Month: "+moment(myDate).format("MM"));_x000D_
console.log("Month: "+moment(myDate).format("MMMM"));_x000D_
console.log("Day: "+moment(myDate).format("DD"));_x000D_
console.log("Day: "+moment(myDate).format("dddd"));_x000D_
console.log("Time: "+moment(myDate).format("HH:mm")); // Time in24 hour format_x000D_
console.log("Time: "+moment(myDate).format("hh:mm A"));

<script src="https://momentjs.com/downloads/moment.js"></script>

Or,

myArray.__len__()

if you want to be oopy; "len(myArray)" is a lot easier to type! :)

Tensorflow on windows needs python 3.5. You can follow following steps to activate python 3.5 in anaconda:

1. See which version of python you have: conda search python
2. If you already have python 3.5 then go to step 3 otherwise use conda create -n py35 python=3.5 anaconda to create python 3.5
3. Activate python 3.5 using activate py35
4. Now install tensorflow using conda install tensorflow

If step4 is not working i.e, something like "tensorflow: no package found " then follow this tutorial to forge conda-forge channel and then try installing tensorflow using step4. It worked for me.

This is BY FAR the easiest way to convert *.cer to *.pfx files:

Just download the portable certificate converter from DigiCert: https://www.digicert.com/util/pfx-certificate-management-utility-import-export-instructions.htm

Execute it, select a file and get your *.pfx!!

Here is how you do it:

In .h

#ifdef BUILD_DLL
#define EXPORT __declspec(dllexport)
#else
#define EXPORT __declspec(dllimport)
#endif

extern "C" // Only if you are using C++ rather than C
{    
  EXPORT int __stdcall add2(int num);
  EXPORT int __stdcall mult(int num1, int num2);
}

in .cpp

extern "C" // Only if you are using C++ rather than C
{    
EXPORT int __stdcall add2(int num)
{
  return num + 2;
}


EXPORT int __stdcall mult(int num1, int num2)
{
  int product;
  product = num1 * num2;
  return product;
}
}

The macro tells your module (i.e your .cpp files) that they are providing the dll stuff to the outside world. People who incude your .h file want to import the same functions, so they sell EXPORT as telling the linker to import. You need to add BUILD_DLL to the project compile options, and you might want to rename it to something obviously specific to your project (in case a dll uses your dll).

You might also need to create a .def file to rename the functions and de-obfuscate the names (C/C++ mangles those names). This blog entry might be an interesting launching off point about that.

Loading your own custom dlls is just like loading system dlls. Just ensure that the DLL is on your system path. C:\windows\ or the working dir of your application are an easy place to put your dll.

A symbolic link to the desired version, defined globally:

sudo ln -s /usr/bin/qmake-qt5 /usr/bin/qmake

... or per user:

sudo ln -s /usr/bin/qmake-qt5 /home/USERNAME/.local/bin/qmake

... to see if it works:

qmake --version

Since the integration of OpenCV is such an effort, we pre-packaged it and published it via JCenter here: https://github.com/quickbirdstudios/opencv-android

Just include this in your module's build.gradle dependencies section

dependencies {
  implementation 'com.quickbirdstudios:opencv:3.4.1'
}

and this in your project's build.gradle repositories section

repositories {
  jcenter()
}

You won't get lint error after gradle import but don't forget to initialize the OpenCV library like this in MainActivity

public class MainActivity extends Activity {
    static {
        if (!OpenCVLoader.initDebug())
            Log.d("ERROR", "Unable to load OpenCV");
        else
            Log.d("SUCCESS", "OpenCV loaded");
    }
...
...
...
...

Using jQuery, easiest way to get array of keys from object is following:

$.map(obj, function(element,index) {return index})

In your case, it will return this array: ["alfa", "beta"]

for me below worked:

chown -R ftpusername /var/app/current

The solution is to simply reinstall ggplot2. Maybe there is an incompatibility between the R version you are using, and your installed version of ggplot2. Alternatively, something might have gone wrong while installing ggplot2 earlier, causing the issue you see.

Support for the extended ternary operator was added in Twig 1.12.0.

1. If foo echo yes else echo no:

   {{ foo ? 'yes' : 'no' }}
   

2. If foo echo it, else echo no:

   {{ foo ?: 'no' }}
   

   or

   {{ foo ? foo : 'no' }}
   

3. If foo echo yes else echo nothing:

   {{ foo ? 'yes' }}
   

   or

   {{ foo ? 'yes' : '' }}
   

4. Returns the value of foo if it is defined and not null, no otherwise:

   {{ foo ?? 'no' }}
   

5. Returns the value of foo if it is defined (empty values also count), no otherwise:

   {{ foo|default('no') }}
   

additionally for accepted answer you can use UseSubmitBehavior="false" MSDN

This works for me:

$ pip install -r requirements.txt --no-index --find-links file:///tmp/packages

--no-index - Ignore package index (only looking at --find-links URLs instead).

-f, --find-links <URL> - If a URL or path to an HTML file, then parse for links to archives.

If a local path or file:// URL that's a directory, then look for archives in the directory listing.

Try this:

var label = $('#currentMonth').text()

puts call the to_s of each argument and adds a new line to each string, if it does not end with new line. print just output each argument by calling their to_s.

for example: puts "one two": one two

{new line}

puts "one two\n": one two

{new line} #puts will not add a new line to the result, since the string ends with a new line

print "one two": one two

print "one two\n": one two

{new line}

And there is another way to output: p

For each object, directly writes obj.inspect followed by a newline to the program’s standard output.

It is helpful to output debugging message. p "aa\n\t": aa\n\t

Cleaner way, exploit shortcut evaluation of shell logical operators. Right side of the operator is executed only if left side is true.

[ ! -d /home/mlzboy/b2c2/shared/db ] && mkdir -p /home/mlzboy/b2c2/shared/db

DBMS_OUTPUT is not the best tool to debug, since most environments don't use it natively. If you want to capture the output of DBMS_OUTPUT however, you would simply use the DBMS_OUTPUT.get_line procedure.

Here is a small example:

SQL> create directory tmp as '/tmp/';

Directory created

SQL> CREATE OR REPLACE PROCEDURE write_log AS
  2     l_line VARCHAR2(255);
  3     l_done NUMBER;
  4     l_file utl_file.file_type;
  5  BEGIN
  6     l_file := utl_file.fopen('TMP', 'foo.log', 'A');
  7     LOOP
  8        EXIT WHEN l_done = 1;
  9        dbms_output.get_line(l_line, l_done);
 10        utl_file.put_line(l_file, l_line);
 11     END LOOP;
 12     utl_file.fflush(l_file);
 13     utl_file.fclose(l_file);
 14  END write_log;
 15  /

Procedure created

SQL> BEGIN
  2     dbms_output.enable(100000);
  3     -- write something to DBMS_OUTPUT

  5     -- write the content of the buffer to a file
  6     write_log;
  7  END;
  8  /

PL/SQL procedure successfully completed

SQL> host cat /tmp/foo.log

this is a test

Dictionary<> is a generic type and so it's type safe.

You can insert any value type in HashTable and this may sometimes throw an exception. But Dictionary<int> will only accept integer values and similarly Dictionary<string> will only accept strings.

So, it is better to use Dictionary<> instead of HashTable.

I haven't reproduced the issue, but perhaps this method would solve it: (writing line by line to stdout rather than using print)

import sys
with open('a.txt', 'r') as f1:
    for line in f1:
        sys.stdout.write(line)

You could catch the broken pipe? This writes the file to stdout line by line until the pipe is closed.

import sys, errno
try:
    with open('a.txt', 'r') as f1:
        for line in f1:
            sys.stdout.write(line)
except IOError as e:
    if e.errno == errno.EPIPE:
        # Handle error

You also need to make sure that othercommand is reading from the pipe before it gets too big - https://unix.stackexchange.com/questions/11946/how-big-is-the-pipe-buffer

You could use smth like this in WPF. I've created example method. Check below.

public string getFolderPath()
{
           // Create OpenFileDialog 
           Microsoft.Win32.OpenFileDialog dlg = new Microsoft.Win32.OpenFileDialog();

           OpenFileDialog openFileDialog = new OpenFileDialog();
           openFileDialog.Multiselect = false;

           openFileDialog.InitialDirectory = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
           if (openFileDialog.ShowDialog() == true)
           {
               System.IO.FileInfo fInfo = new System.IO.FileInfo(openFileDialog.FileName);

The obvious answer wasn't there in all the responses.
PHP has a neat streaming delimiter parser available made for exactly that purpose.

$fp = fopen("/path/to/the/file", "r+");
while (($line = stream_get_line($fp, 1024 * 1024, "\n")) !== false) {
  echo $line;
}
fclose($fp);

str(c) returns a new string representation of c, and does not mutate c itself.

c = str(c) 

is probably what you are looking for

This works without changing the validation mode.

You have to use a System.Web.Helpers.Validation.Unvalidated helper from System.Web.WebPages.dll. It is going to return a UnvalidatedRequestValues object which allows to access the form and QueryString without validation.

For example,

var queryValue = Server.UrlDecode(Request.Unvalidated("MyQueryKey"));

Works for me for MVC3 and .NET 4.

If you have a hardcoded image URL, for example: http://example.com/image.jpg you can use php to add headers to your image.

First you will have to make apache process your jpg as php. See here: Is it possible to execute PHP with extension file.php.jpg?

Load the image (imagecreatefromjpeg) from file then add the headers from previous answers. Use php function header to add the headers.

Then output the image with the imagejpeg function.

Please notice that it's very insecure to let php process jpg images. Also please be aware I haven't tested this solution so it is up to you to make it work.

If you've done all this and it still doesn't work, check the expiry for that user:

X-Frame-Options is deprecated. From MDN:

This feature has been removed from the Web standards. Though some browsers may still support it, it is in the process of being dropped. Do not use it in old or new projects. Pages or Web apps using it may break at any time.

The modern alternative is the Content-Security-Policy header, which along many other policies can white-list what URLs are allowed to host your page in a frame, using the frame-ancestors directive.
frame-ancestors supports multiple domains and even wildcards, for example:

Content-Security-Policy: frame-ancestors 'self' example.com *.example.net ;

Unfortunately, for now, Internet Explorer does not fully support Content-Security-Policy.

UPDATE: MDN has removed their deprecation comment. Here's a similar comment from W3C's Content Security Policy Level

The frame-ancestors directive obsoletes the X-Frame-Options header. If a resource has both policies, the frame-ancestors policy SHOULD be enforced and the X-Frame-Options policy SHOULD be ignored.

this worked for me for c#

If you are looking for a Python implementation of find, this is a recipe I use rather frequently:

from findtools.find_files import (find_files, Match)

# Recursively find all *.sh files in **/usr/bin**
sh_files_pattern = Match(filetype='f', name='*.sh')
found_files = find_files(path='/usr/bin', match=sh_files_pattern)

for found_file in found_files:
    print found_file

So I made a PyPI package out of it and there is also a GitHub repository. I hope that someone finds it potentially useful for this code.

Just try to create the marker and set the draggable property to true. The code will be something as follows:

Marker = new google.maps.Marker({
    position: latlon,
    map: map,            
    draggable: true,
    title: "Drag me!"
});

I hope this helps!

While LIKE is suitable for this case, a more general purpose solution is to use instr, which doesn't require characters in the search string to be escaped. Note: instr is available starting from Sqlite 3.7.15.

SELECT *
  FROM TABLE  
 WHERE instr(column, 'cats') > 0;

Also, keep in mind that LIKE is case-insensitive, whereas instr is case-sensitive.

I was able to solve by simply filling in 127.0.0.1 for the PostgreSQL host address rather than leaving it blank. (Django Example)

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME': 'database_name',
        'USER': 'database_user',
        'PASSWORD': 'pass',
        'HOST': '127.0.0.1',
        'PORT': '',
        }
}

function Person(){
  if(Person.count == undefined){
    Person.count = 1;
  }
  else{
    Person.count ++;
  }
  console.log(Person.count);
}

var p1 = new Person();
var p2 = new Person();
var p3 = new Person();

You can also use,

output <- as.matrix(as.data.frame(z))

The memory usage is very similar to

output <- matrix(unlist(z), ncol = 10, byrow = TRUE)

Which can be verified, with mem_changed() from library(pryr).

Yes, else can be used in Python inside a list comprehension with a Conditional Expression ("ternary operator"):

>>> [("A" if b=="e" else "c") for b in "comprehension"]
['c', 'c', 'c', 'c', 'c', 'A', 'c', 'A', 'c', 'c', 'c', 'c', 'c']

Here, the parentheses "()" are just to emphasize the conditional expression, they are not necessarily required (Operator precedence).

Additionaly, several expressions can be nested, resulting in more elses and harder to read code:

>>> ["A" if b=="e" else "d" if True else "x" for b in "comprehension"]
['d', 'd', 'd', 'd', 'd', 'A', 'd', 'A', 'd', 'd', 'd', 'd', 'd']
>>>

On a related note, a comprehension can also contain its own if condition(s) at the end:

>>> ["A" if b=="e" else "c" for b in "comprehension" if False]
[]
>>> ["A" if b=="e" else "c" for b in "comprehension" if "comprehension".index(b)%2]
['c', 'c', 'A', 'A', 'c', 'c']

Conditions? Yes, multiple ifs are possible, and actually multiple fors, too:

>>> [i for i in range(3) for _ in range(3)]
[0, 0, 0, 1, 1, 1, 2, 2, 2]
>>> [i for i in range(3) if i for _ in range(3) if _ if True if True]
[1, 1, 2, 2]

(The single underscore _ is a valid variable name (identifier) in Python, used here just to show it's not actually used. It has a special meaning in interactive mode)

Using this for an additional conditional expression is possible, but of no real use:

>>> [i for i in range(3)]
[0, 1, 2]
>>> [i for i in range(3) if i]
[1, 2]
>>> [i for i in range(3) if (True if i else False)]
[1, 2]

Comprehensions can also be nested to create "multi-dimensional" lists ("arrays"):

>>> [[i for j in range(i)] for i in range(3)]
[[], [1], [2, 2]]

Last but not least, a comprehension is not limited to creating a list, i.e. else and if can also be used the same way in a set comprehension:

>>> {i for i in "set comprehension"}
{'o', 'p', 'm', 'n', 'c', 'r', 'i', 't', 'h', 'e', 's', ' '}

and a dictionary comprehension:

>>> {k:v for k,v in [("key","value"), ("dict","comprehension")]}
{'key': 'value', 'dict': 'comprehension'}

The same syntax is also used for Generator Expressions:

>>> for g in ("a" if b else "c" for b in "generator"):
...     print(g, end="")
...
aaaaaaaaa>>>

which can be used to create a tuple (there is no tuple comprehension).

I used font-family: "Quicksand", sans-serif;

This is the import of the font (goes in the top of the style.css)

@import url("https://fonts.googleapis.com/css2?family=Quicksand:wght@300&display=swap");

If you want to rewrite the url, you have to change your site virtualhost adding this lines:

### Enabling mod_rewrite
Options FollowSymLinks
RewriteEngine on

### Rewrite http:// => https://
RewriteCond %{SERVER_PORT} 80$
RewriteRule ^(.*)$ https://%{HTTP_HOST}$1 [R=301,NC,L]

But, if you want to redirect all your requests on the port 80 to the port 443 of the web servers behind the proxy, you can try this example conf on your haproxy.cfg:

Plots created using seaborn need to be displayed like ordinary matplotlib plots. This can be done using the

plt.show()

function from matplotlib.

Originally I posted the solution to use the already imported matplotlib object from seaborn (sns.plt.show()) however this is considered to be a bad practice. Therefore, simply directly import the matplotlib.pyplot module and show your plots with

import matplotlib.pyplot as plt
plt.show()

If the IPython notebook is used the inline backend can be invoked to remove the necessity of calling show after each plot. The respective magic is

%matplotlib inline

Don't forget the option "-o", which lets you download anywhere you want, although you have to create "archives", "lock" and "partial" first (the command prints what's needed).

apt-get install -d -o=dir::cache=/tmp whateveryouwant

There is a sorting algorithm in the standard library, in the header <algorithm>. It sorts inplace, so if you do the following, your original word will become sorted.

std::sort(word.begin(), word.end());

If you don't want to lose the original, make a copy first.

std::string sortedWord = word;
std::sort(sortedWord.begin(), sortedWord.end());

An email address must not exceed 254 characters.

This was accepted by the IETF following submitted erratum. A full diagnosis of any given address is available online. The original version of RFC 3696 described 320 as the maximum length, but John Klensin subsequently accepted an incorrect value, since a Path is defined as

Path = "<" [ A-d-l ":" ] Mailbox ">"

So the Mailbox element (i.e., the email address) has angle brackets around it to form a Path, which a maximum length of 254 characters to restrict the Path length to 256 characters or fewer.

The maximum length specified in RFC 5321 states:

The maximum total length of a reverse-path or forward-path is 256 characters.

RFC 3696 was corrected here.

People should be aware of the errata against RFC 3696 in particular. Three of the canonical examples are in fact invalid addresses.

I've collated a couple hundred test addresses, which you can find at http://www.dominicsayers.com/isemail

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysql.sock' (2)

I get the error above when I try to log into MYSQL after installing it using brew, I am running MacOs, Oh yea I also noticed mysql is running I have restarted numerous times with no luck resolving the issue along with removing mysql and numerous reinstalls!

So simple I could slap myself, no but really, I solved this by CD into the temp folder that contains mysqlx.sock and mysql.sock.lock files, I deleted the single sock.lock file only and this solved my issue after doing so and I can log into mysql using the mysql -uroot command. Here are the commands I used. (this issue had me hung up for a while)

~ cd /tmp 

/tmp ls 

(this will list all the sock files in the temp folder, output shown below)

com.apple.launchd.8AgGW2s9Bb mysql.sock.lock
com.apple.launchd.batxrSISAJ mysqlx.sock
com.apple.launchd.cRCaxtT41m mysqlx.sock.lock
com.google.Keystone          powerlog

then run

rm -R mysql.sock.lock 

(use command above to remove the sock.lock file from the /tmp directory this resolved my issue)

hope this helped :)

Test its side-effects. This includes:

• Does it throw any exceptions? (If it should, check that it does. If it shouldn't, try some corner cases which might if you're not careful - null arguments being the most obvious thing.)
• Does it play nicely with its parameters? (If they're mutable, does it mutate them when it shouldn't and vice versa?)
• Does it have the right effect on the state of the object/type you're calling it on?

Of course, there's a limit to how much you can test. You generally can't test with every possible input, for example. Test pragmatically - enough to give you confidence that your code is designed appropriately and implemented correctly, and enough to act as supplemental documentation for what a caller might expect.

You can check the called attribute, but if your assertion fails, the next thing you'll want to know is something about the unexpected call, so you may as well arrange for that information to be displayed from the start. Using unittest, you can check the contents of call_args_list instead:

self.assertItemsEqual(my_var.call_args_list, [])

When it fails, it gives a message like this:

AssertionError: Element counts were not equal:
First has 0, Second has 1:  call('first argument', 4)

The request type is multipart/form-data and what you are sending is essentially form fields that go out as bytes with content boundaries separating different form fields.To send an object representation as form field (string), you can send a serialized form from the client that you can then deserialize on the server.

After all no programming environment object is actually ever traveling on the wire. The programming environment on both side are just doing automatic serialization and deserialization that you can also do. That is the cleanest and programming environment quirks free way to do it.

As an example, here is a javascript client posting to a Jersey example service,

submitFile(){

    let data = new FormData();
    let account = {
        "name": "test account",
        "location": "Bangalore"
    }

    data.append('file', this.file);
    data.append("accountKey", "44c85e59-afed-4fb2-884d-b3d85b051c44");
    data.append("device", "test001");
    data.append("account", JSON.stringify(account));
    
    let url = "http://localhost:9090/sensordb/test/file/multipart/upload";

    let config = {
        headers: {
            'Content-Type': 'multipart/form-data'
        }
    }

    axios.post(url, data, config).then(function(data){
        console.log('SUCCESS!!');
        console.log(data.data);
    }).catch(function(){
        console.log('FAILURE!!');
    });
},

Here the client is sending a file, 2 form fields (strings) and an account object that has been stringified for transport. here is how the form fields look on the wire,

On the server, you can just deserialize the form fields the way you see fit. To finish this trivial example,

    @POST
@Path("/file/multipart/upload")
@Consumes({MediaType.MULTIPART_FORM_DATA})
public Response uploadMultiPart(@Context ContainerRequestContext requestContext,
        @FormDataParam("file") InputStream fileInputStream,
        @FormDataParam("file") FormDataContentDisposition cdh,
        @FormDataParam("accountKey") String accountKey,
        @FormDataParam("account") String json)  {
    

    
    System.out.println(cdh.getFileName());
    System.out.println(cdh.getName());
    System.out.println(accountKey);
    
    try {
        Account account = Account.deserialize(json);
        System.out.println(account.getLocation());
        System.out.println(account.getName());
        
    } catch (Exception e) {
        e.printStackTrace();
    }
    
    return Response.ok().build();
    
}

"If I want two columns for anything over 768px, should I apply both classes?"

No need to add the col-lg-6 too.

The latest version of Eclipse (Luna) and Spring Tool Suite (STS) come pre-packaged with support for Maven, GIT and Java 8.

Now this may include more than you need (and may not even work for command line applications in a non-graphical environment, I don't know), but there is nw.js. It's Blink (i.e. Chromium/Webkit) + io.js (i.e. Node.js).

You can use node-webkit-builder to build native executable binaries for Linux, OS X and Windows.

If you want a GUI, that's a huge plus. You can build one with web technologies. If you don't, specify "node-main" in the package.json (and probably "window": {"show": false} although maybe it works to just have a node-main and not a main)

I haven't tried to use it in exactly this way, just throwing it out there as a possibility. I can say it's certainly not an ideal solution for non-graphical Node.js applications.

Instead of doing this:

compile "com.android.support:support-v4:18.0.+"

Do this:

compile 'com.android.support:support-v4:18.0.+'

Give it a try!

Thanks for enlightening us Cypawer.

and it worked flawlessly.

To DELETE, without changing the references, you should first delete or otherwise alter (in a manner suitable for your purposes) all relevant rows in other tables.

To TRUNCATE you must remove the references. TRUNCATE is a DDL statement (comparable to CREATE and DROP) not a DML statement (like INSERT and DELETE) and doesn't cause triggers, whether explicit or those associated with references and other constraints, to be fired. Because of this, the database could be put into an inconsistent state if TRUNCATE was allowed on tables with references. This was a rule when TRUNCATE was an extension to the standard used by some systems, and is mandated by the the standard, now that it has been added.

Use :

<select onchange="myFunction()">

    function myFunction() {
        document.querySelectorAll("input[type=submit]")[0].click();
    }

Well you can ask the help of regex, the great in here :)

code:

import re

string = 'adsfg34wrtwe4r2_()' #your string that needs to be matched.
regex = r'^[\w\d_()]*$' # you can also add a space in regex if u want to allow it in the string  
if re.match(regex,string):
    print 'yes'
else: 
    print 'false'

Output:

yes  

Hope this helps :)

The Rule is: when inside a string, use \n wherever you want a new line; you do not have to put a space before or after the \n, JavaScript's interpreter is smart enough to know how long the unprintable character representation is.

I like, with git log, to do:

 git log --graph --oneline --branches

(also with --all, for viewing remote branches as well)

Works with recent Git releases: introduced since 1.6.3 (Thu, 7 May 2009)

• "--pretty=<style>" option to the log family of commands can now be spelled as "--format=<style>".
  In addition, --format=%formatstring is a short-hand for --pretty=tformat:%formatstring.

• "--oneline" is a synonym for "--pretty=oneline --abbrev-commit".

PS D:\git\tests\finalRepo> git log --graph --oneline --branches --all
* 4919b68 a second bug10 fix
* 3469e13 a first bug10 fix
* dbcc7aa a first legacy evolution

| | * 47e6ee1 a second bug10 fix
| | * 8183707 a first bug10 fix
| |/
| * e727105 a second evol for 2.0
| * 473d44e a main evol
|/
* b68c1f5 first evol, for making 1.0

You can also limit the span of the log display (number of commits):

PS D:\git\tests\finalRepo> git log --graph --oneline --branches --all -5
* 4919b68 a second bug10 fix
* 3469e13 a first bug10 fix
* dbcc7aa a first legacy evolution
| * 55aac85 another main evol
| | * 47e6ee1 a second bug10 fix

(show only the last 5 commits)

What I do not like about the current selected solution is:

 git log --graph

It displayed way too much info (when I want only to look at a quick summary):

gitk is great, but forces me to leave the shell session for another window, whereas displaying the last n commits quickly is often enough.

If you are using Apache reverse proxy for serving an app running on a localhost port you must add a location to your vhost.

<Location />            
   ProxyPass http://localhost:1339/ retry=0
   ProxyPassReverse http://localhost:1339/
   ProxyPreserveHost On
   ProxyErrorOverride Off
</Location>

To get the IP address have following options

console.log(">>>", req.ip);// this works fine for me returned a valid ip address 
console.log(">>>", req.headers['x-forwarded-for'] );// returned a valid IP address 
console.log(">>>", req.headers['X-Real-IP'] ); // did not work returned undefined 
console.log(">>>", req.connection.remoteAddress );// returned the loopback IP address 

So either use req.ip or req.headers['x-forwarded-for']

Probably if you haven't solved it yet ... the class name uses accented letters ...

Based on my experience with AngularJS modals so far I believe that the most elegant approach is a dedicated service to which we can provide a partial (HTML) template to be displayed in a modal.

When we think about it modals are kind of AngularJS routes but just displayed in modal popup.

The AngularUI bootstrap project (http://angular-ui.github.com/bootstrap/) has an excellent $modal service (used to be called $dialog prior to version 0.6.0) that is an implementation of a service to display partial's content as a modal popup.

No, there is no CSS property for minimum or maximum font size. Browsers often have a setting for minimum font size, but that’s under the control of the user, not an author.

You can use @media queries to make some CSS settings depending on things like screen or window width. In such settings, you can e.g. set the font size to a specific small value if the window is very narrow.

Seems like your host does not provide a MySQL-version which is capable to run tables with utf8mb4 collation.

The WordPress tables were changed to utf8mb4 with Version 4.2 (released on April, 23rd 2015) to support Emojis, but you need MySQL 5.5.3 to use it. 5.5.3. is from March 2010, so it should normally be widely available. Cna you check if your hoster provides that version?

If not, and an upgrade is not possible, you might have to look out for another hoster to run the latest WordPress versions (and you should always do that for security reasons).

If you want to create table with data . First create the table :

create table new_table as ( select * from old_table); 

and then insert

insert into new_table ( select * from old_table);

If you want to create table without data . You can use :

create table new_table as ( select * from old_table where 1=0);

use colspan for do this

 <td colspan="3">PUR mix up column</td>

since most of the devices use eMMC,the file system android uses is ext4,except for the firmware.refer-http://android-developers.blogspot.com/2010/12/saving-data-safely.html

Here is the filesystem on galaxy s4:

• /system ext4

• /data ext4

• /cache ext4

• /firmware vfat

• /data/media /mnt/shell/emulated sdcardfs

The detailed output is as follows:

You need to add runat="server" and and to assign an ID for it, then specify the absolute path like this:

<script type="text/javascript" runat="server" id="myID" src="~/js/jquery.jqGrid.js"></script>]

From the codebehind, you can change the src programatically using the ID.

This might be helpful:

columns.Bound(date=> date.START_DATE).Title("Start Date").Format("{0:MM dd, yyyy}");

b = a[a>threshold] this should do

I tested as follows:

import numpy as np, datetime
# array of zeros and ones interleaved
lrg = np.arange(2).reshape((2,-1)).repeat(1000000,-1).flatten()

t0 = datetime.datetime.now()
flt = lrg[lrg==0]
print datetime.datetime.now() - t0

t0 = datetime.datetime.now()
flt = np.array(filter(lambda x:x==0, lrg))
print datetime.datetime.now() - t0

I got

$ python test.py
0:00:00.028000
0:00:02.461000

Deletion of a topic has been supported since 0.8.2.x version. You have to enable topic deletion (setting delete.topic.enable to true) on all brokers first.

Note: Ever since 1.0.x, the functionality being stable, delete.topic.enable is by default true.

Follow this step by step process for manual deletion of topics

1. Stop Kafka server
2. Delete the topic directory, on each broker (as defined in the logs.dirs and log.dir properties) with rm -rf command
3. Connect to Zookeeper instance: zookeeper-shell.sh host:port
4. From within the Zookeeper instance:
   1. List the topics using: ls /brokers/topics
   2. Remove the topic folder from ZooKeeper using: rmr /brokers/topics/yourtopic
   3. Exit the Zookeeper instance (Ctrl+C)
5. Restart Kafka server
6. Confirm if it was deleted or not by using this command kafka-topics.sh --list --zookeeper host:port

This will return all the values matching your key valueTitle

subList.SelectMany(m => m).Where(kvp => kvp.Key == "valueTitle").Select(k => k.Value).ToList();

To do anything other than declare a pointer to an object, you need the full definition.

The best solution is to move the implementation in a separate file.

If you must keep this in a header, move the definition after both declarations:

class tile_tree_apple;

class tile_tree : public tile
{
  public:
      tile onDestroy();
      tile tick();
      void onCreate();        
};

class tile_tree_apple : public tile
{
  public:
      tile onDestroy();
      tile tick();
      void onCreate(); 
      tile onUse();       
};

tile tile_tree::onDestroy() {return *new tile_grass;};
tile tile_tree::tick() {if (rand()%20==0) return *new tile_tree_apple;};
void tile_tree::onCreate() {health=rand()%5+4; type=TILET_TREE;};        

tile tile_tree_apple::onDestroy() {return *new tile_grass;};
tile tile_tree_apple::tick() {if (rand()%20==0) return *new tile_tree;};
void tile_tree_apple::onCreate() {health=rand()%5+4; type=TILET_TREE_APPLE;}; 
tile tile_tree_apple::onUse() {return *new tile_tree;};       

Important

You have memory leaks:

tile tile_tree::onDestroy() {return *new tile_grass;};

will create an object on the heap, which you can't destroy afterwards, unless you do some ugly hacking. Also, your object will be sliced. Don't do this, return a pointer.

My example to your questions:

def get_sublist(row, col1, col2):
    return mylist[row[col1]:row[col2]+1]
df.apply(get_sublist, axis=1, col1='col_1', col2='col_2')

User extend AppCompatActivity & it will work !!

In the case of some programs, these errors are normal and should not be fixed.

I get these error messages when compiling the program phrap (for example). This program happens to contain code that modifies or replaces some built in functions, and when I include the appropriate header files to fix the warnings, GCC instead generates a bunch of errors. So fixing the warnings effectively breaks the build.

If you got the source as part of a distribution that should compile normally, the errors might be normal. Consult the documentation to be sure.

   String ns = Context.NOTIFICATION_SERVICE;
  NotificationManager Nmang = (NotificationManager) getApplicationContext()
                                                     .getSystemService(ns);
  Nmang .cancel(getIntent().getExtras().getInt("notificationID"));

An absolute xpath in HTML DOM starts with /html e.g.

/html/body/div[5]/div[2]/div/div[2]/div[2]/h2[1]

and a relative xpath finds the closed id to the dom element and generates xpath starting from that element e.g.

.//*[@id='answers']/h2[1]/a[1]

You can use firepath (firebug) for generating both types of xpaths

It won't make any difference which xpath you use in selenium, the former may be faster than the later one (but it won't be observable)

Absolute xpaths are prone to more regression as slight change in DOM makes them invalid or refer to a wrong element

Concatenation you say? How about #concat method then?

a = 'foo'
a.object_id #=> some number
a.concat 'bar' #=> foobar
a.object_id #=> same as before -- string a remains the same object

In all fairness, concat is aliased as <<.

If you want to setup for temporary purpose, just execute below command.

1. open command prompt < run --> cmd >
2. Run below command.
   set PATH=C:\Program Files\Git\bin;%PATH%
3. Type git, it will work.

This is valid for current window/cell only, if you will close command prompt, everything will get vanish. For permanently setting, set GIT in environment variable.

a. press Window+Pause
b. click on Advance system setting.

c. Click on Environment variable under Advance Tab.

d. Edit Path Variable.

e. Add below line in end of statement.
;c:\Program Files\Git\bin;

f. Press OK!!
g. Open new command prompt .
h. Type git and press Enter

Thanks

The message that you are getting is not for the default Exception of Python:

For a fresh python list, IndexError is thrown only on index not being in range (even docs say so).

>>> l = []
>>> l[1]
IndexError: list index out of range

If we try passing multiple items to list, or some other value, we get the TypeError:

>>> l[1, 2]
TypeError: list indices must be integers, not tuple

>>> l[float('NaN')]
TypeError: list indices must be integers, not float

However, here, you seem to be using matplotlib that internally uses numpy for handling arrays. On digging deeper through the codebase for numpy, we see:

static NPY_INLINE npy_intp
unpack_tuple(PyTupleObject *index, PyObject **result, npy_intp result_n)
{
    npy_intp n, i;
    n = PyTuple_GET_SIZE(index);
    if (n > result_n) {
        PyErr_SetString(PyExc_IndexError,
                        "too many indices for array");
        return -1;
    }
    for (i = 0; i < n; i++) {
        result[i] = PyTuple_GET_ITEM(index, i);
        Py_INCREF(result[i]);
    }
    return n;
}

where, the unpack method will throw an error if it the size of the index is greater than that of the results.

So, Unlike Python which raises a TypeError on incorrect Indexes, Numpy raises the IndexError because it supports multidimensional arrays.

That code transforms any bootstrap table row that has data-href attribute set into a clickable element

Note: data-href attribute is a valid tr attribute (HTML5), href attributes on tr element are not.

$(function(){
    $('.table tr[data-href]').each(function(){
        $(this).css('cursor','pointer').hover(
            function(){ 
                $(this).addClass('active'); 
            },  
            function(){ 
                $(this).removeClass('active'); 
            }).click( function(){ 
                document.location = $(this).attr('data-href'); 
            }
        );
    });
});

Because LINQ can do everything...:

string test = "key1=value1&key2=value2&key3=value3";
var count = test.Where(x => x == '&').Count();

Or if you like, you can use the Count overload that takes a predicate :

var count = test.Count(x => x == '&');

If you are running tomcat from eclipse (probably problem exists with another IDEs), it could have a different configuration- not based on files .

The solution is to edit tomcat users file, as you wrote, and then start tomcat from command prompt with

{tomcat-directory}/bin/startup

Problem: An XML parser returns the error “xmlParseEntityRef: noname”

Cause: There is a stray ‘&’ (ampersand character) somewhere in the XML text eg. some text & some more text

Solution:

• Solution 1: Remove the ampersand.
• Solution 2: Encode the ampersand (that is replace the & character with & ). Remember to Decode when reading the XML text.
• Solution 3: Use CDATA sections (text inside a CDATA section will be ignored by the parser.) eg. <![CDATA[some text & some more text]]>

Note: ‘&’ ‘<' '>‘ will all give problems if not handled correctly.

import yaml

data = dict(
    A = 'a',
    B = dict(
        C = 'c',
        D = 'd',
        E = 'e',
    )
)

with open('data.yml', 'w') as outfile:
    yaml.dump(data, outfile, default_flow_style=False)

The default_flow_style=False parameter is necessary to produce the format you want (flow style), otherwise for nested collections it produces block style:

A: a
B: {C: c, D: d, E: e}

This helped me to call API that was using cookie authentication. I have passed authorization in header like this:

request.Headers.Set("Authorization", Utility.Helper.ReadCookie("AuthCookie"));

complete code:

// utility method to read the cookie value:
        public static string ReadCookie(string cookieName)
        {
            var cookies = HttpContext.Current.Request.Cookies;
            var cookie = cookies.Get(cookieName);
            if (cookie != null)
                return cookie.Value;
            return null;
        }

your jump link looks like this

<a href="#div_id">jump link</a>

Then make

<div id="div_id"></div>

the jump link will take you to that div

Here is the example in which you can easily find the way to use Post,GET method and use the same way to add other curd operations as well..

#libraries to include

import os
from flask import request, jsonify
from app import app, mongo
import logger
ROOT_PATH = os.environ.get('ROOT_PATH')<br>
@app.route('/get/questions/', methods=['GET', 'POST','DELETE', 'PATCH'])
    def question():
    # request.args is to get urls arguments 


    if request.method == 'GET':
        start = request.args.get('start', default=0, type=int)
        limit_url = request.args.get('limit', default=20, type=int)
        questions = mongo.db.questions.find().limit(limit_url).skip(start);
        data = [doc for doc in questions]
        return jsonify(isError= False,
                    message= "Success",
                    statusCode= 200,
                    data= data), 200

# request.form to get form parameter

    if request.method == 'POST':
        average_time = request.form.get('average_time')
        choices = request.form.get('choices')
        created_by = request.form.get('created_by')
        difficulty_level = request.form.get('difficulty_level')
        question = request.form.get('question')
        topics = request.form.get('topics')

    ##Do something like insert in DB or Render somewhere etc. it's up to you....... :)

$ ssh-add -l 

will also work on Mac OS X v10.8 (Mountain Lion) - v10.10 (Yosemite).

It also supports the option -E to specify the fingerprint format so in case MD5 is needed (it's often used, e.g. by GitHub), just add -E md5 to the command.

If you want to stick with the way you're populating the values array, you can then assign this array like so:

BODY.values = values;

after the loop.

It should look like this:

var BODY = {
    "recipients": {
      "values": [
     ]
    },
   "subject": title,
   "body": message
}

var values = [];
for (var ln = 0; ln < names.length; ln++) {
var item1 = {
    "person": {
            "_path": "/people/"+names[ln],
            },
};
values.push(item1);
}
BODY.values = values;
alert(BODY);

JSON.stringify() will be useful once you pass it as parameter for an AJAX call. Remember: the values array in your BODY object is different from the var values = []. You must assign that outer values[] to BODY.values. This is one of the good things about OOP.

The simplest way I found was suggested by leontalbot (as a comment), which is a post published by Anoopjohn. I think its worth its own space as an answer:

(I converted it to a bash script)

#!/bin/bash
if [[ $1 == "" ]]; then
    echo "Usage: $0 FILE_OR_DIR [remote]";
    echo "FILE_OR_DIR: the file or directory you want to remove from history"
    echo "if 'remote' argument is set, it will also push to remote repository."
    exit;
fi
FOLDERNAME_OR_FILENAME=$1;

#The important part starts here: ------------------------

git filter-branch -f --index-filter "git rm -rf --cached --ignore-unmatch $FOLDERNAME_OR_FILENAME" -- --all
rm -rf .git/refs/original/
git reflog expire --expire=now --all
git gc --prune=now
git gc --aggressive --prune=now

if [[ $2 == "remote" ]]; then
    git push --all --force
fi
echo "Done."

All credits goes to Annopjohn, and to leontalbot for pointing it out.

NOTE

Be aware that the script doesn't include validations, so be sure you don't make mistakes and that you have a backup in case something goes wrong. It worked for me, but it may not work in your situation. USE IT WITH CAUTION (follow the link if you want to know what is going on).
