Programs & Examples On #Associative array

Oh I found it in the PHP manual.

foreach ($array as $key => $value){
    statement
}

The current element's key will be assigned to the variable $key on each loop.

Sometimes I use a prefixes for my keys. For example:

var pre = 'foo',
    key = pre + 1234

obj = {};

obj[key] = val;

Now you don't have any problem accessing them.

Java doesn't support associative arrays, however this could easily be achieved using a Map. E.g.,

Map<String, String> map = new HashMap<String, String>();
map.put("name", "demo");
map.put("fname", "fdemo");
// etc

map.get("name"); // returns "demo"

Even more accurate to your example (since you can replace String with any object that meet your needs) would be to declare:

List<Map<String, String>> data = new ArrayList<>();
data.add(0, map);
data.get(0).get("name"); 

See the official documentation for more information

A bit of speed comparison for all mentioned methods:

ECMAScript 6 has spread syntax. And now you can do this:

const obj1 = { 1: 11, 2: 22 };_x000D_
const obj2 = { 3: 33, 4: 44 };_x000D_
const obj3 = { ...obj1, ...obj2 };_x000D_
_x000D_
console.log(obj3); // {1: 11, 2: 22, 3: 33, 4: 44}

I create HashMaps in bash 3 using dynamic variables. I explained how that works in my answer to: Associative arrays in Shell scripts

Also you can take a look in shell_map, which is a HashMap implementation made in bash 3.

While Hash#has_key? gets the job done, as Matz notes here, it has been deprecated in favour of Hash#key?.

hash.key?(some_key)

The keys are accessed using an exclamation point: ${!array[@]}, the values are accessed using ${array[@]}.

You can iterate over the key/value pairs like this:

for i in "${!array[@]}"
do
  echo "key  : $i"
  echo "value: ${array[$i]}"
done

Note the use of quotes around the variable in the for statement (plus the use of @ instead of *). This is necessary in case any keys include spaces.

The confusion in the other answer comes from the fact that your question includes "foo" and "bar" for both the keys and the values.

A few people before me mentioned the .pop trick to delete and create a key in a one-liner.

I personally find the more explicit implementation more readable:

d = {'a': 1, 'b': 2}
v = d['b']
del d['b']
d['c'] = v

The code above returns {'a': 1, 'c': 2}

You could use a second associative array that maps human readable names to the id's. That would also provide a Many to 1 relationship. Then do something like this:

echo 'Widgets: ' . $data[$humanreadbleMapping['Widgets']];

You can simply do this

$data += array($category => $question);

If your're running on php 5.4+

$data += [$category => $question];

You can use http_build_query() to do that.

Generates a URL-encoded query string from the associative (or indexed) array provided.

Associative array in PHP actually considered as a dictionary.

An array in PHP is actually an ordered map. A map is a type that associates values to keys. it can be treated as an array, list (vector), hash table (an implementation of a map), dictionary, collection, stack, queue, and probably more.

<?php
$array = array(
    "foo" => "bar",
    "bar" => "foo",
);

// Using the short array syntax
$array = [
    "foo" => "bar",
    "bar" => "foo",
];
?>

An array is different than a dictionary in that arrays have both an index and a key. Dictionaries only have keys and no index.

I think you are looking for the Dictionary object, found in the Microsoft Scripting Runtime library. (Add a reference to your project from the Tools...References menu in the VBE.)

It pretty much works with any simple value that can fit in a variant (Keys can't be arrays, and trying to make them objects doesn't make much sense. See comment from @Nile below.):

Dim d As dictionary
Set d = New dictionary

d("x") = 42
d(42) = "forty-two"
d(CVErr(xlErrValue)) = "Excel #VALUE!"
Set d(101) = New Collection

You can also use the VBA Collection object if your needs are simpler and you just want string keys.

I don't know if either actually hashes on anything, so you might want to dig further if you need hashtable-like performance. (EDIT: Scripting.Dictionary does use a hash table internally.)

Agreed that it is probably best practice to keep Objects as objects and Arrays as arrays. However, if you have an Object with named properties that you are treating as an array, here is how it can be done:

let tempArr = [];
Object.keys(objectArr).forEach( (element) => {
    tempArr.push(objectArr[element]);
});

let json = JSON.stringify(tempArr);

If it is the first element, i.e. $array[0], you can try:

echo key($array);

If it is the second element, i.e. $array[1], you can try:

next($array);
echo key($array);

I think this method is should be used when required element is the first, second or at most third element of the array. For other cases, loops should be used otherwise code readability decreases.

In bash version 4 associative arrays were introduced.

declare -A arr

arr["key1"]=val1

arr+=( ["key2"]=val2 ["key3"]=val3 )

The arr array now contains the three key value pairs. Bash is fairly limited what you can do with them though, no sorting or popping etc.

for key in ${!arr[@]}; do
    echo ${key} ${arr[${key}]}
done

Will loop over all key values and echo them out.

Note: Bash 4 does not come with Mac OS X because of its GPLv3 license; you have to download and install it. For more on that see here

####################################################################
# Bash v3 does not support associative arrays
# and we cannot use ksh since all generic scripts are on bash
# Usage: map_put map_name key value
#
function map_put

Example:

mapName=$(basename $0)_map_
map_put $mapName "name" "Irfan Zulfiqar"
map_put $mapName "designation" "SSE"

for key in $(map_keys $mapName)
do
    echo "$key = $(map_get $mapName $key)
done

In response to MK_Dev, one is able to iterate, but not consecutively (for that, obviously an array is needed).

A quick Google search brings up hash tables in JavaScript.

Example code for looping over values in a hash (from the aforementioned link):

var myArray = new Array();
myArray['one'] = 1;
myArray['two'] = 2;
myArray['three'] = 3;

// Show the values stored
for (var i in myArray) {
    alert('key is: ' + i + ', value is: ' + myArray[i]);
}

I stumbled upon this question trying to identify a clean way to join two assoc arrays.

I was trying to join two different tables that didn't have relationships to each other.

This is what I came up with for PDO Query joining two Tables. Samuel Cook is what identified a solution for me with the array_merge() +1 to him.

        $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
        $sql = "SELECT * FROM ".databaseTbl_Residential_Prospects."";
        $ResidentialData = $pdo->prepare($sql);
        $ResidentialData->execute(array($lapi));
        $ResidentialProspects = $ResidentialData->fetchAll(PDO::FETCH_ASSOC);

        $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
        $sql = "SELECT * FROM ".databaseTbl_Commercial_Prospects."";
        $CommercialData = $pdo->prepare($sql);
        $CommercialData->execute(array($lapi));
        $CommercialProspects = $CommercialData->fetchAll(PDO::FETCH_ASSOC);

        $Prospects = array_merge($ResidentialProspects,$CommercialProspects);
        echo '<pre>';
        var_dump($Prospects);
        echo '</pre>';

Maybe this will help someone else out.

    var myObj = [];
    myObj['Base'] = [];
    myObj['Base']['Base.panel.panel_base'] = {ContextParent:'',ClassParent:'',NameParent:'',Context:'Base',Class:'panel',Name:'panel_base',Visible:'',ValueIst:'',ValueSoll:'',
                                              Align:'',  AlignFrom:'',AlignTo:'',Content:'',onClick:'',Style:'',content_ger_sie:'',content_ger_du:'',content_eng:'' };
    myObj['Base']['Base.panel.panel_top']  = {ContextParent:'',ClassParent:'',NameParent:'',Context:'Base',Class:'panel',Name:'panel_base',Visible:'',ValueIst:'',ValueSoll:'',
                                              Align:'',AlignFrom:'',AlignTo:'',Content:'',onClick:'',Style:'',content_ger_sie:'',content_ger_du:'',content_eng:'' };

    myObj['SC1'] = [];
    myObj['SC1']['Base.panel.panel_base'] = {ContextParent:'',ClassParent:'',NameParent:'',Context:'Base',Class:'panel',Name:'panel_base',Visible:'',ValueIst:'',ValueSoll:'',
                                              Align:'',  AlignFrom:'',AlignTo:'',Content:'',onClick:'',Style:'',content_ger_sie:'',content_ger_du:'',content_eng:'' };
    myObj['SC1']['Base.panel.panel_top']  = {ContextParent:'',ClassParent:'',NameParent:'',Context:'Base',Class:'panel',Name:'panel_base',Visible:'',ValueIst:'',ValueSoll:'',
                                              Align:'',AlignFrom:'',AlignTo:'',Content:'',onClick:'',Style:'',content_ger_sie:'',content_ger_du:'',content_eng:'' };


    console.log(myObj);

    if ('Base' in myObj) {
      console.log('Base found');

      if ('Base.panel.panel_base' in myObj['Base'])  {
        console.log('Base.panel.panel_base found'); 


      console.log('old value: ' + myObj['Base']['Base.panel.panel_base'].Context);  
      myObj['Base']['Base.panel.panel_base'] = 'new Value';
      console.log('new value: ' + myObj['Base']['Base.panel.panel_base']);
      }
    }

Output:

• Base found
• Base.panel.panel_base found
• old value: Base
• new value: new Value

The array operation works. There is no problem.

Iteration:

     Object.keys(myObj['Base']).forEach(function(key, index) {            
        var value = objcons['Base'][key];                   
      }, myObj);

foreach($test_package_data as $key=>$data ) {

   $category_detail_arr = $test_package_data[$key]['category_detail'];

   foreach( $category_detail_arr as $i=>$value ) {
     $test_package_data[$key]['category_detail'][$i]['count'] = $some_value;////<----Here
   }

}

a simple code snippet that i prepared, hope it will be usefull for you;

$ages = array("Kerem"=>"35","Ahmet"=>"65","Talip"=>"62","Kamil"=>"60");

reset($ages);

for ($i=0; $i < count($ages); $i++){
echo "Key : " . key($ages) . " Value : " . current($ages) . "<br>";
next($ages);
}
reset($ages);

foreach($data as $value)
{
    $value["transaction_date"] = date('d/m/Y',$value["transaction_date"]);
}
return $data;

We can use it as a function too. Angular throws some error if used as a prototype. Thanks @HarpyWar. It helped me solve a problem.

var removeItem = function (object, key, value) {
    if (value == undefined)
        return;

    for (var i in object) {
        if (object[i][key] == value) {
            object.splice(i, 1);
        }
    }
};

var collection = [
    { id: "5f299a5d-7793-47be-a827-bca227dbef95", title: "one" },
    { id: "87353080-8f49-46b9-9281-162a41ddb8df", title: "two" },
    { id: "a1af832c-9028-4690-9793-d623ecc75a95", title: "three" }
];

removeItem(collection, "id", "87353080-8f49-46b9-9281-162a41ddb8df");

UPDATE will change only the columns you specifically list.

UPDATE some_table
SET field1='Value 1'
WHERE primary_key = 7;

The WHERE clause limits which rows are updated. Generally you'd use this to identify your table's primary key (or ID) value, so that you're updating only one row.

The SET clause tells MySQL which columns to update. You can list as many or as few columns as you'd like. Any that you do not list will not get updated.

Do not always use Redirect permanent (or why it may cause issues in future)

If there is a chance that you will add subdomains later, do not use redirect permanent.

Because if a client has used a subdomain that wasn't registred as VirtualHost he may also never reach this subdomain even when it is registred later.

redirect permanent sends an HTTP 301 Moved Permanently to the client (browser) and a lot of them cache this response for ever (until cache is cleared [manually]). So using that subdomain will always autoredirect to www.*** without requesting the server again.

see How long do browsers cache HTTP 301s?

So just use Redirect

<VirtualHost *:80>
  ServerName example.com

  Redirect / http://www.example.com/
</VirtualHost>

I had the same problem and I had solved it with:

1.Right click to solution and click 'Clean Solution'

2.Click 'References' folder in solution explorer and select the problem reference (in your case it seems System.Web.Mvc) and then right click and click 'Properties'.

3.In the properties window, make sure that the 'Copy Local' property is set to 'True'

This worked for me. Hope it works for someone else

Helpful Note: As it has mentioned in comments by @Vlad:

If it is already set to True:

1. Set it False
2. Set it True again
3. Rebuild

All of

std::string s(1, c); std::cout << s << std::endl;

and

and

std::string s; s.push_back(c); std::cout << s << std::endl;

worked for me.

I think op wants to know what the font that is used on a webpage is, and hoped that info might be findable in the 'inspect' pane.

I was trying to write in nodejs and finally came up with this:

db.collection('collectionName').mapReduce(
function() {
    for (var key in this) {
        emit(key, null);
    }
},
function(key, stuff) {
    return null;
}, {
    "out": "allFieldNames"
},
function(err, results) {
    var fields = db.collection('allFieldNames').distinct('_id');
    fields
        .then(function(data) {
            var finalData = {
                "status": "success",
                "fields": data
            };
            res.send(finalData);
            delteCollection(db, 'allFieldNames');
        })
        .catch(function(err) {
            res.send(err);
            delteCollection(db, 'allFieldNames');
        });
 });

After reading the newly created collection "allFieldNames", delete it.

db.collection("allFieldNames").remove({}, function (err,result) {
     db.close();
     return; 
});

axiac's solution is what worked best for me in the end. I had an additional complexity however: a calculated "max value", derived from two columns.

Let's use the same example: I would like the oldest person in each group. If there are people that are equally old, take the tallest person.

I had to perform the left join two times to get this behavior:

SELECT o1.* WHERE
    (SELECT o.*
    FROM `Persons` o
    LEFT JOIN `Persons` b
    ON o.Group = b.Group AND o.Age < b.Age
    WHERE b.Age is NULL) o1
LEFT JOIN
    (SELECT o.*
    FROM `Persons` o
    LEFT JOIN `Persons` b
    ON o.Group = b.Group AND o.Age < b.Age
    WHERE b.Age is NULL) o2
ON o1.Group = o2.Group AND o1.Height < o2.Height 
WHERE o2.Height is NULL;

Hope this helps! I guess there should be better way to do this though...

Except for some internal logging, Close == Dispose.

Dispose calls tcpClient.Client.Shutdown( SocketShutdown.Both ), but its eats any errors. Maybe if you call it directly, you can get some useful exception information.

You can use ISNULL:

ISNULL(field, VALUEINCASEOFNULL)

Just put the two files in the same directory. Here's an example:

Person.java

public class Person {
  public String name;

  public Person(String name) {
    this.name = name;
  }

  public String toString() {
    return name;
  }
}

Student.java

public class Student extends Person {
  public String somethingnew;

  public Student(String name) {
    super(name);
    somethingnew = "surprise!";
  }

  public String toString() {
    return super.toString() + "\t" + somethingnew;
  }

  public static void main(String[] args) {
    Person you = new Person("foo");
    Student me = new Student("boo");

    System.out.println("Your name is " + you);
    System.out.println("My name is " + me);
  }
}

Running Student (since it has the main function) yields us the desired outcome:

Your name is foo
My name is boo  surprise!

From the MySQL manual

INSERT statements that use VALUES syntax can insert multiple rows. To do this, include multiple lists of column values, each enclosed within parentheses and separated by commas. Example:

INSERT INTO tbl_name (a,b,c) VALUES(1,2,3),(4,5,6),(7,8,9);

All the above did not work for me (XCode 7.3) so I read Apple reference on how to do, and it is much simpler than described above. According to Apple:

Localized values are not stored in the Info.plist file itself. Instead, you store the values for a particular localization in a strings file with the name InfoPlist.strings. You place this file in the same language-specific project directory that you use to store other resources for the same localization.

Accordingly, I created a string file named InfoPlist.strings and placed it in the xx.lproj folder of the "xx" language (and added it to the project using File->Add Files to ...). That's it. No need for the key "Localized resources can be mixed" = YES, and no need for InfoPlist.strings in base.lproj or en.lproj.

The application uses the Info.plist key-value as the default value if it can not find a key in the language specific file. Thus, I put my English value in the Info.plist file and the translated one in the language specific file, tested and everything works.

In particular, there is no need to localize the InfoPlist.strings (which creates a version of the file in the base.lproj, en.lroj, and xx.lproj), and in my case going that way did not work.

The following worked for me

const conString = "postgres://YourUserName:YourPassword@YourHostname:5432/YourDatabaseName";

One can also nullify parent's line height:

#wrapper {
  line-height: 0;
}

By default X-Frame-Options is set to denied, to prevent clickjacking attacks. To override this, you can add the following into your spring security config

<http>    
    <headers>
        <frame-options policy="SAMEORIGIN"/>
    </headers>
</http>

Here are available options for policy

• DENY - is a default value. With this the page cannot be displayed in a frame, regardless of the site attempting to do so.
• SAMEORIGIN - I assume this is what you are looking for, so that the page will be (and can be) displayed in a frame on the same origin as the page itself
• ALLOW-FROM - Allows you to specify an origin, where the page can be displayed in a frame.

For more information take a look here.

And here to check how you can configure the headers using either XML or Java configs.

Note, that you might need also to specify appropriate strategy, based on needs.

You may want to go a step further and do this on a nested hash. Certainly this happens a fair amount with Rails projects.

Here's some code to ensure a params hash is in UTF-8:

  def convert_hash hash
    hash.inject({}) do |h,(k,v)|
      if v.kind_of? String
        h[k] = to_utf8(v) 
      else
        h[k] = convert_hash(v)
      end
      h
    end      
  end    

  # Iconv UTF-8 helper
  # Converts strings into valid UTF-8
  #
  # @param [String] untrusted_string the string to convert to UTF-8
  # @return [String] your string in UTF-8
  def to_utf8 untrusted_string=""
    ic = Iconv.new('UTF-8//IGNORE', 'UTF-8')
    ic.iconv(untrusted_string + ' ')[0..-2]
  end  

Just use:

var d = new Date();
document.write(d.toLocaleString());
document.write("<br>");

The exception occurs due to this statement,

called_from.equalsIgnoreCase("add")

It seem that the previous statement

String called_from = getIntent().getStringExtra("called");

returned a null reference.

You can check whether the intent to start this activity contains such a key "called".

The main difference from other solutions here is that this one reuses logic in RequiredAttribute on the server side, and uses required's validation method depends property on the client side:

public class RequiredIf : RequiredAttribute, IClientValidatable
{
    public string OtherProperty { get; private set; }
    public object OtherPropertyValue { get; private set; }

    public RequiredIf(string otherProperty, object otherPropertyValue)
    {
        OtherProperty = otherProperty;
        OtherPropertyValue = otherPropertyValue;
    }

    protected override ValidationResult IsValid(object value, ValidationContext validationContext)
    {
        PropertyInfo otherPropertyInfo = validationContext.ObjectType.GetProperty(OtherProperty);
        if (otherPropertyInfo == null)
        {
            return new ValidationResult($"Unknown property {OtherProperty}");
        }

        object otherValue = otherPropertyInfo.GetValue(validationContext.ObjectInstance, null);
        if (Equals(OtherPropertyValue, otherValue)) // if other property has the configured value
            return base.IsValid(value, validationContext);

        return null;
    }

    public IEnumerable<ModelClientValidationRule> GetClientValidationRules(ModelMetadata metadata, ControllerContext context)
    {
        var rule = new ModelClientValidationRule();
        rule.ErrorMessage = FormatErrorMessage(metadata.GetDisplayName());
        rule.ValidationType = "requiredif"; // data-val-requiredif
        rule.ValidationParameters.Add("other", OtherProperty); // data-val-requiredif-other
        rule.ValidationParameters.Add("otherval", OtherPropertyValue); // data-val-requiredif-otherval

        yield return rule;
    }
}

$.validator.unobtrusive.adapters.add("requiredif", ["other", "otherval"], function (options) {
    var value = {
        depends: function () {
            var element = $(options.form).find(":input[name='" + options.params.other + "']")[0];
            return element && $(element).val() == options.params.otherval;
        }
    }
    options.rules["required"] = value;
    options.messages["required"] = options.message;
});

    view.setSystemUiVisibility(uiOption);
    ActionBar actionBar = getActionBar();
    if (actionBar != null) {
        actionBar.hide();
    }
}

You can do this locally as everyone mentioned using

git checkout -b <branch-name> <sha1-of-commit>

Alternatively, you can do this in github itself, follow the steps:

1- In the repository, click on the Commits.

2- on the commit you want to branch from, click on <> to browse the repository at this point in the history.

3- Click on the tree: xxxxxx in the upper left. Just type in a new branch name there click Create branch xxx as shown below.

Now you can fetch the changes from that branch locally and continue from there.

Very good answer using inheritance, just remember to override the initializer

public class Utf8StringWriter : StringWriter
{
    public Utf8StringWriter(StringBuilder sb) : base (sb)
    {
    }
    public override Encoding Encoding { get { return Encoding.UTF8; } }
}

Meaning.

In brief, $@ expands to the positional arguments passed from the caller to either a function or a script. Its meaning is context-dependent: Inside a function, it expands to the arguments passed to such function. If used in a script (not inside the scope a function), it expands to the arguments passed to such script.

$ cat my-sh
#! /bin/sh
echo "$@"

$ ./my-sh "Hi!"
Hi!

$ put () ( echo "$@" )
$ put "Hi!"
Hi!

Word splitting.

Now, another topic that is of paramount importance when understanding how $@ behaves in the shell is word splitting. The shell splits tokens based on the contents of the IFS variable. Its default value is \t\n; i.e., whitespace, tab, and newline.

Expanding "$@" gives you a pristine copy of the arguments passed. However, expanding $@ will not always. More specifically, if the arguments contain characters from IFS, they will split.

Most of the time what you will want to use is "$@", not $@.

They are simply showed like this:

_______________________
|   <<enumeration>>   |
|    DaysOfTheWeek    |
|_____________________|
| Sunday              |
| Monday              |
| Tuesday             |
| ...                 |
|_____________________|

And then just have an association between that and your class.

You shouldn't use float unless you have to. In 99% of cases, double is a better choice.

int x = 1111111111;
int y = 10000;
float f = (float) x / y;
double d = (double) x / y;
System.out.println("f= "+f);
System.out.println("d= "+d);

prints

f= 111111.12
d= 111111.1111

Following @Matt's comment.

float has very little precision (6-7 digits) and shows significant rounding error fairly easily. double has another 9 digits of accuracy. The cost of using double instead of float is notional in 99% of cases however the cost of a subtle bug due to rounding error is much higher. For this reason, many developers recommend not using floating point at all and strongly recommend BigDecimal.

However I find that double can be used in most cases provided sensible rounding is used.

In this case, int x has 32-bit precision whereas float has a 24-bit precision, even dividing by 1 could have a rounding error. double on the other hand has 53-bit of precision which is more than enough to get a reasonably accurate result.

  RegistryKey rkSubKey = Registry.CurrentUser.OpenSubKey(" Your Registry Key Location", false);
        if (rkSubKey == null)
        {
           // It doesn't exist
        }
        else
        {
           // It exists and do something if you want to
         }

Use the $_SERVER['HTTP_REFERER'] header, but bear in mind anybody can spoof it at anytime regardless of whether they clicked on a link.

Just add the ? sign after index.php in the .htaccess file :

RewriteEngine on
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L]

and it would work !

On http://www.google.com/earth/media/licensing.html there is a "Mobile" section containing :

Similar to our online terms, if you use our APIs or a mobile device’s native Google Maps implementation (such as on an Android-powered phone or iPhone), no special permission is required, but you must always keep the Google name visible. Offline caching of our content is never allowed.

Use the below function (changing [E:E] to the appropriate range for your needs) to circumvent this issue (or change to any other format such as "mm/dd/yyyy"):

[E:E].Select

    .NumberFormat = "General"
    .Value = .Value
End With

P.S. In my experience, this VBA solution works SIGNIFICANTLY faster on large data sets and is less likely to crash Excel than using the 'warning box' method.

Just worked out for another solution as above example have bug( somewhere error ) for me. Variation from the selected answer.

html,body {
    height: 100%
}

#nonFooter {
    min-height: 100%;
    position:relative;
    /* Firefox */
    min-height: -moz-calc(100% - 30px);
    /* WebKit */
    min-height: -webkit-calc(100% - 30px);
    /* Opera */
    min-height: -o-calc(100% - 30px);
    /* Standard */
    min-height: calc(100% - 30px);
}

#footer {
    height:30px;
    margin: 0;
    clear: both;
    width:100%;
    position: relative;
}

for html layout

<body>
    <div id="nonFooter">header,middle,left,right,etc</div>
    <div id="footer"></div>
</body>

Well this way don't support old browser however its acceptable for old browser to scrolldown 30px to view the footer

• plunker

hi firstly there seems to be many 'errors' in your html where you are missing closing tags, you could try wrapping the contents of your <body> in a fixed width <div style="margin: 0 auto; width: 900px> to achieve what you have done with the body {margin: 0 10% 0 10%}

I don't think other answers explained the key part: why "COUNT(*)" returns more than one result?

I just encountered the same issue today, and what I found out is that if you have another class extending the target mapped class (here "CustomerData"), Hibernate will do this magic.

Hope this will save some time for other unfortunate guys.

Hmmm... I would almost swear that this worked for the original Bourne shell, but don't have access to a running copy just now to check.

There is, however, a very trivial workaround to the problem.

Change the first line of the script from:

#!/bin/bash

to

#!/bin/ksh

Et voila! A read at the end of a pipeline works just fine, assuming you have the Korn shell installed.

You might try changing this line in your persistence.xml from

<property name="hbm2ddl.auto" value="create"/>

to:

<property name="hibernate.hbm2ddl.auto" value="update"/>

This is supposed to maintain the schema to follow any changes you make to the Model each time you run the app.

Got this from JavaRanch

On Windows plattform with server execute command:

netstat -a -b

look for sql server processes and find port f.e 49198

Or easier. Connect with dbvisualizer, run netstat -a -b find dbvis.exe process and get port.

I don't think it is possible to share a database link between more than one user but not all. They are either private (for one user only) or public (for all users).

A good way around this is to create a view in SCHEMA_B that exposes the table you want to access through the database link. This will also give you good control over who is allowed to select from the database link, as you can control the access to the view.

Do like this:

create database link db_link... as before;
create view mytable_view as select * from mytable@db_link;
grant select on mytable_view to myuser;

In this situation, Snackbar is the better option then Toast to display the quit action. Here is the method with snackbar that works.

@Override
        public void onBackPressed() {
            if (doubleBackToExitPressedOnce) {
                super.onBackPressed();
                return;
            }
            this.doubleBackToExitPressedOnce = true;
            Snackbar.make(this.getWindow().getDecorView().findViewById(android.R.id.content), "Please click BACK again to exit", Snackbar.LENGTH_SHORT).show();

            new Handler().postDelayed(new Runnable() {

                @Override
                public void run() {
                    doubleBackToExitPressedOnce=false;
                }
            }, 2000);
        }

you can see the result here In these simple block of code you can change the size of your image ,and make it bigger when the mouse enter over the image , and it will return to its original size when mouve leave.

html:

<div>
<img  onmouseover="fifo()" onmouseleave="fifo()" src="your_image"   
       width="10%"  id="f" >
</div>

js file:

var b=0;
function fifo() {
       if(b==0){
            document.getElementById("f").width = "300";
           b=1;
          }
       else
          {
         document.getElementById("f").width = "100";
          b=0;
        }
   }

Please follow these steps

1. In User Variables

   Set VARIABLE NAME=ANT_HOME VARIABLE PATH =C:\Program Files\apache-ant-1.9.7

2.Edit User Variable PATH = %ANT_HOME%\bin

3. Go to System Variables

   • Set Path =%ANT_HOME%\bin

First you store your text file in to raw folder.

private void loadWords() throws IOException {
    Log.d(TAG, "Loading words...");
    final Resources resources = mHelperContext.getResources();
    InputStream inputStream = resources.openRawResource(R.raw.definitions);
    BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));

    try {
        String line;
        while ((line = reader.readLine()) != null) {
            String[] strings = TextUtils.split(line, "-");
            if (strings.length < 2)
                continue;
            long id = addWord(strings[0].trim(), strings[1].trim());
            if (id < 0) {
                Log.e(TAG, "unable to add word: " + strings[0].trim());
            }
        }
    } finally {
        reader.close();
    }
    Log.d(TAG, "DONE loading words.");
}

You can do:

for f in *.txt; do (cat "${f}"; echo) >> finalfile.txt; done

Make sure the file finalfile.txt does not exist before you run the above command.

If you are allowed to use awk you can do:

awk 'FNR==1{print ""}1' *.txt > finalfile.txt

You cannot check window.history.length as it contains the amount of pages in you visited in total in a given session:

window.history.length (Integer)

Read-only. Returns the number of elements in the session history, including the currently loaded page. For example, for a page loaded in a new tab this property returns 1. ^{Cite 1}

Lets say a user visits your page, clicks on some links and goes back:

www.mysite.com/index.html <-- first page and now current page                  <----+
www.mysite.com/about.html                                                           |
www.mysite.com/about.html#privacy                                                   | 
www.mysite.com/terms.html <-- user uses backbutton or your provided solution to go back

Now window.history.length is 4. You cannot traverse through the history items due to security reasons. Otherwise on could could read the user's history and get his online banking session id or other sensitive information.

You can set a timeout, that will enable you to act if the previous page isn't loaded in a given time. However, if the user has a slow Internet connection and the timeout is to short, this method will redirect him to your default location all the time:

window.goBack = function (e){
    var defaultLocation = "http://www.mysite.com";
    var oldHash = window.location.hash;

    history.back(); // Try to go back

    var newHash = window.location.hash;

    /* If the previous page hasn't been loaded in a given time (in this case
    * 1000ms) the user is redirected to the default location given above.
    * This enables you to redirect the user to another page.
    *
    * However, you should check whether there was a referrer to the current
    * site. This is a good indicator for a previous entry in the history
    * session.
    *
    * Also you should check whether the old location differs only in the hash,
    * e.g. /index.html#top --> /index.html# shouldn't redirect to the default
    * location.
    */

    if(
        newHash === oldHash &&
        (typeof(document.referrer) !== "string" || document.referrer  === "")
    ){
        window.setTimeout(function(){
            // redirect to default location
            window.location.href = defaultLocation;
        },1000); // set timeout in ms
    }
    if(e){
        if(e.preventDefault)
            e.preventDefault();
        if(e.preventPropagation)
            e.preventPropagation();
    }
    return false; // stop event propagation and browser default event
}

<span class="goback" onclick="goBack();">Go back!</span>

Note that typeof(document.referrer) !== "string" is important, as browser vendors can disable the referrer due to security reasons (session hashes, custom GET URLs). But if we detect a referrer and it's empty, it's probaly save to say that there's no previous page (see note below). Still there could be some strange browser quirk going on, so it's safer to use the timeout than to use a simple redirection.

EDIT: Don't use <a href='#'>...</a>, as this will add another entry to the session history. It's better to use a <span> or some other element. Note that typeof document.referrer is always "string" and not empty if your page is inside of a (i)frame.

• W3C: HTML5: 5.4.2 The History interface

The location has changed from Java 6 (provided by Apple) to Java 7 and onwards (provided by Oracle). The best generic way to find this out is to run

/usr/libexec/java_home

This is the natively supported way to find out both the path to the default Java installation as well as all alternative ones present.

If you check out its help text (java_home -h), you'll see that you can use this command to reliably start a Java program on OS X (java_home --exec ...), with the ability to explicitly specify the desired Java version and architecture, or even request the user to install it if missing.

A more pedestrian approach, but one which will help you trace specifically which Java installation the command java resolves into, goes like this:

1. run

   which java
   

2. if that gives you something like /usr/bin/java, which is a symbolic link to the real location, run

   ls -l `which java`
   

   On my system, this outputs

   /usr/bin/java -> /Library/Java/JavaVirtualMachines/jdk1.7.0_25.jdk/Contents/Home/bin/java
   

   and therefrom you can read the Java home directory;

3. if usr/bin/java points to another symbolic link, recursively apply the same approach with

   ls -l <whatever the /usr/bin/java symlink points to>
   

An important variation is the setup you get if you start by installing Apple's Java and later install Oracle's. In that case Step 2 above will give you

/usr/bin/java -> /System/Library/Frameworks/JavaVM.framework/Commands/java

and that particular java binary is a stub which will resolve the actual java command to call by consulting the JAVA_HOME environment variable and, if it's not set or doesn't point to a Java home directory, will fall back to calling java_home. It is important to have this in mind when debugging your setup.

An open source GUI tool is available at keystore-explorer.org

VBA has a CurDir keyword that will return the "current directory" as stored in Excel. I'm not sure all the things that affect the current directory, but definitely opening or saving a workbook will change it.

MyWorkbook.SaveAs CurDir & Application.PathSeparator & "MySavedWorkbook.xls"

This assumes that the sheet you want to save has never been saved and you want to define the file name in code.

You don't need to call $.toJSON and add traditional = true

data: { sendInfo: array },
traditional: true

would do.

This is a good summary I found:

The Carriage Return (CR) character (0x0D, \r) moves the cursor to the beginning of the line without advancing to the next line. This character is used as a new line character in Commodore and Early Macintosh operating systems (OS-9 and earlier).

The Line Feed (LF) character (0x0A, \n) moves the cursor down to the next line without returning to the beginning of the line. This character is used as a new line character in UNIX based systems (Linux, Mac OSX, etc)

The End of Line (EOL) sequence (0x0D 0x0A, \r\n) is actually two ASCII characters, a combination of the CR and LF characters. It moves the cursor both down to the next line and to the beginning of that line. This character is used as a new line character in most other non-Unix operating systems including Microsoft Windows, Symbian OS and others.

Jaanna, the session parameters in Oracle SQL Developer are dependent on your client computer, while the NLS parameters on PL/SQL is from server.

For example the NLS_NUMERIC_CHARACTERS on client computer can be ',.' while it's '.,' on server.

So when you run script from PL/SQL and Oracle SQL Developer the decimal separator can be completely different for the same script, unless you alter session with your expected NLS_NUMERIC_CHARACTERS in the script.

One way to easily test your session parameter is to do:

select to_number(5/2) from dual;

The fastest way yuo get over it is to replace origin with the suggestion it gives.

Instead of git push origin master, use:

git push [email protected]:my_user_name/my_repo.git master

git checkout -b NEW_BRANCH_NAME COMMIT_ID

This will create a new branch called 'NEW_BRANCH_NAME' and check it out.

("check out" means "to switch to the branch")

git branch NEW_BRANCH_NAME COMMIT_ID

This just creates the new branch without checking it out.

in the comments many people seem to prefer doing this in two steps. here's how to do so in two steps:

git checkout COMMIT_ID
# you are now in the "detached head" state
git checkout -b NEW_BRANCH_NAME

I tried to use the \x00 and it didn't work for me when using C# and Regex. I had success with the following:

//The hexidecimal 0x0 is the null character  
mystring.Contains(Convert.ToChar(0x0).ToString() );  

// This will replace the character
mystring = mystring.Replace(Convert.ToChar(0x0).ToString(), "");

Java 8 now supports default methods, which are similar to C#'s extension methods.

If you use Kotlin, you can add an extension method to Image in the same manner Sri Harsha Chilakapati suggests.

fun Image.toBufferedImage(): BufferedImage {
    if (this is BufferedImage) {
        return this
    }
    val bufferedImage = BufferedImage(this.getWidth(null), this.getHeight(null), BufferedImage.TYPE_INT_ARGB)

    val graphics2D = bufferedImage.createGraphics()
    graphics2D.drawImage(this, 0, 0, null)
    graphics2D.dispose()

    return bufferedImage
}

And use it like this:

myImage.toBufferedImage()

I know it has been a while since this was asked, but I learned an alternative yesterday

We all know you can do:

if(o instanceof String) {   // etc

but what if you dont know exactly what type of class it needs to be? you cannot generically do:

if(o instanceof <Class variable>.getClass()) {   

as it gives a compile error.
Instead, here is an alternative - isAssignableFrom()

For example:

public static boolean isASubClass(Class classTypeWeWant, Object objectWeHave) {

    return classTypeWeWant.isAssignableFrom(objectWeHave.getClass())
}

I was having an error The library com.google.android.gms:play-services-measurement-base is being requested by various other libraries at [[16.0.2,16.0.2]], but resolves to 16.0.0. Disable the plugin and check your dependencies tree using ./gradlew :app:dependencies.

If you want to measure CPU time, can use time.process_time() for Python 3.3 and above:

import time
start = time.process_time()
# your code here    
print(time.process_time() - start)

First call turns the timer on, and second call tells you how many seconds have elapsed.

There is also a function time.clock(), but it is deprecated since Python 3.3 and will be removed in Python 3.8.

There are better profiling tools like timeit and profile, however time.process_time() will measure the CPU time and this is what you're are asking about.

If you want to measure wall clock time instead, use time.time().

For those using the Google API Client Library for PHP and seeking offline access and refresh tokens beware as of the time of this writing the docs are showing incorrect examples.

currently it's showing:

$client = new Google_Client();
$client->setAuthConfig('client_secret.json');
$client->addScope(Google_Service_Drive::DRIVE_METADATA_READONLY);
$client->setRedirectUri('http://' . $_SERVER['HTTP_HOST'] . '/oauth2callback.php');
// offline access will give you both an access and refresh token so that
// your app can refresh the access token without user interaction.
$client->setAccessType('offline');
// Using "consent" ensures that your application always receives a refresh token.
// If you are not using offline access, you can omit this.
$client->setApprovalPrompt("consent");
$client->setIncludeGrantedScopes(true);   // incremental auth

source: https://developers.google.com/identity/protocols/OAuth2WebServer#offline

All of this works great - except ONE piece

$client->setApprovalPrompt("consent");

After a bit of reasoning I changed this line to the following and EVERYTHING WORKED

$client->setPrompt("consent");

It makes sense since using the HTTP requests it was changed from approval_prompt=force to prompt=consent. So changing the setter method from setApprovalPrompt to setPrompt follows natural convention - BUT IT'S NOT IN THE DOCS!!! That I found at least.

you can use LayoutInflater to inflate your dynamic data as a layout file.

UPDATE : first create a LinearLayout inside your CardView's layout and assign an ID for it. after that create a layout file that you want to inflate. at last in your onBindViewHolder method in your "RAdaper" class. write these codes :

  mInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

  view = mInflater.inflate(R.layout.my_list_custom_row, parent, false);

after that you can initialize data and ClickListeners with your RAdapter Data. hope it helps.

this and this may useful :)

Standard CSS3 rotate should work in IE9, but I believe you need to give it a vendor prefix, like so:

  -ms-transform: rotate(10deg);

It is possible that it may not work in the beta version; if not, try downloading the current preview version (preview 7), which is a later revision that the beta. I don't have the beta version to test against, so I can't confirm whether it was in that version or not. The final release version is definitely slated to support it.

I can also confirm that the IE-specific filter property has been dropped in IE9.

[Edit]
People have asked for some further documentation. As they say, this is quite limited, but I did find this page: http://css3please.com/ which is useful for testing various CSS3 features in all browsers.

But testing the rotate feature on this page in IE9 preview caused it to crash fairly spectacularly.

However I have done some independant tests using -ms-transform:rotate() in IE9 in my own test pages, and it is working fine. So my conclusion is that the feature is implemented, but has got some bugs, possibly related to setting it dynamically.

Another useful reference point for which features are implemented in which browsers is www.canIuse.com -- see http://caniuse.com/#search=rotation

[EDIT]
Reviving this old answer because I recently found out about a hack called CSS Sandpaper which is relevant to the question and may make things easier.

The hack implements support for the standard CSS transform for for old versions of IE. So now you can add the following to your CSS:

-sand-transform: rotate(10deg);

...and have it work in IE 6/7/8, without having to use the filter syntax. (of course it still uses the filter syntax behind the scenes, but this makes it a lot easier to manage because it's using similar syntax to other browsers)

To access the elements in the array, use array notation: $product['prodname']

$product->prodname is object notation, which can only be used to access object attributes and methods.

Here is a Common Lisp example that does factorials using tail-recursion. Due to the stack-less nature, one could perform insanely large factorial computations ...

(defun ! (n &optional (product 1))
    (if (zerop n) product
        (! (1- n) (* product n))))

And then for fun you could try (format nil "~R" (! 25))

Not the answer for this question

I got this exception when trying to delete a folder where i deleted the file inside.

Example:

createFolder("folder");  
createFile("folder/file");  
deleteFile("folder/file");  
deleteFolder("folder"); // error here

While deleteFile("folder/file"); returned that it was deleted, the folder will only be considered empty after the program restart.

On some operating systems it may not be possible to remove a file when it is open and in use by this Java virtual machine or other programs.

Explanation from dhke

I'm not sure what you mean by "myself".

Any JavaScript function can be called by an event, but you must have some sort of event to trigger it.

e.g. On page load:

<body onload="myfunction();">

Or on mouseover:

<table onmouseover="myfunction();">

As a result the first question is, "What do you want to do to cause the function to execute?"

After you determine that it will be much easier to give you a direct answer.

EAFP vs. LBYL

I understand your dilemma, but Python is not PHP and coding style known as Easier to Ask for Forgiveness than for Permission (or EAFP in short) is a common coding style in Python.

See the source (from documentation):

EAFP - Easier to ask for forgiveness than permission. This common Python coding style assumes the existence of valid keys or attributes and catches exceptions if the assumption proves false. This clean and fast style is characterized by the presence of many try and except statements. The technique contrasts with the LBYL style common to many other languages such as C.

So, basically, using try-catch statements here is not a last resort; it is a common practice.

"Arrays" in Python

PHP has associative and non-associative arrays, Python has lists, tuples and dictionaries. Lists are similar to non-associative PHP arrays, dictionaries are similar to associative PHP arrays.

If you want to check whether "key" exists in "array", you must first tell what type in Python it is, because they throw different errors when the "key" is not present:

>>> l = [1,2,3]
>>> l[4]

Traceback (most recent call last):
  File "<pyshell#2>", line 1, in <module>
    l[4]
IndexError: list index out of range
>>> d = {0: '1', 1: '2', 2: '3'}
>>> d[4]

Traceback (most recent call last):
  File "<pyshell#6>", line 1, in <module>
    d[4]
KeyError: 4

And if you use EAFP coding style, you should just catch these errors appropriately.

LBYL coding style - checking indexes' existence

If you insist on using LBYL approach, these are solutions for you:

• for lists just check the length and if possible_index < len(your_list), then your_list[possible_index] exists, otherwise it doesn't:

  >>> your_list = [0, 1, 2, 3]
  >>> 1 < len(your_list) # index exist
  True
  >>> 4 < len(your_list) # index does not exist
  False
  

• for dictionaries you can use in keyword and if possible_index in your_dict, then your_dict[possible_index] exists, otherwise it doesn't:

  >>> your_dict = {0: 0, 1: 1, 2: 2, 3: 3}
  >>> 1 in your_dict # index exists
  True
  >>> 4 in your_dict # index does not exist
  False
  

Did it help?

If you are using ajax then (making it as simple as possible)

1. Add your loading gif image to html and make it hidden (using style in html itself now, you can add it to separate CSS):

   <img src="path\to\loading\gif" id="img" style="display:none"/ >
   

2. Show the image when button is clicked and hide it again on success function

   $('#buttonID').click(function(){
     $('#img').show(); //<----here
     $.ajax({
       ....
      success:function(result){
          $('#img').hide();  //<--- hide again
      }
   }
   

Make sure you hide the image on ajax error callbacks too to make sure the gif hides even if the ajax fails.

Here a reagent solution for a input component that has a :focus property.

The field will be focused as long as this prop is set to true and will not have focus as long as this is false.

Unfortunately this component needs to have a :ref defined, I could not find an other way to call .focus() on it. I am happy about suggestions.

(defn focusable-input [init-attrs]
  (r/create-class
    {:display-name "focusable-input"
     :component-will-receive-props
       (fn [this new-argv]
         (let [ref-c (aget this "refs" (:ref init-attrs))
               focus (:focus (ru/extract-props new-argv))
               is-focused (.isFocused ref-c)]
           (if focus
             (when-not is-focused (.focus ref-c))
             (when is-focused (.blur ref-c)))))
     :reagent-render
       (fn [attrs]
         (let [init-focus (:focus init-attrs)
               auto-focus (or (:auto-focus attrs) init-focus)
               attrs (assoc attrs :auto-focus auto-focus)]
           [input attrs]))}))

You can use within <td> tag css : display:inline-block

Like: <td style="display:inline-block">

Upload your favicon.ico to the root directory of your website and that should work with Chrome. Some browsers disregard the meta tag and just use /favicon.ico

Go figure?.....

if you are using razor engine template then do the following

in your view write :

<script> var myJsVariable = '@ViewBag.MyVariable' </script>

UPDATE: A more appropriate approach is to define a set of configuration on the master layout for example, base url, facebook API Key, Amazon S3 base URL, etc ...```

<head>
 <script>
   var AppConfig = @Html.Raw(Json.Encode(new {
    baseUrl: Url.Content("~"),
    fbApi: "get it from db",
    awsUrl: "get it from db"
   }));
 </script>
</head>

And you can use it in your JavaScript code as follow:

<script>
  myProduct.fullUrl = AppConfig.awsUrl + myProduct.path;
  alert(myProduct.fullUrl);
</script>

System.Diagnostics.Process.Start("http://www.webpage.com");

One of many ways.

The shell script below also worked nicely for me... definite had to use the redirect that Antonin mentioned at first... that gave me the idea to test the here document.

function testMongoScript {
    mongo <<EOF
    use mydb
    db.leads.findOne()
    db.leads.find().count()
EOF
}

this part :

"Your new price is: $"(float(price)

asks python to call this string:

"Your new price is: $"

just like you would a function: function( some_args) which will ALWAYS trigger the error:

TypeError: 'str' object is not callable

Right-click the assembly reference in the solution explorer, properties, disable the "Specific Version" option.

In java 8 , It's really easy to get timestamp in UTC by using java 8 java.time.Instant library :

Instant.now();

That few word of code will return the UTC Timestamp.

You can use this

@echo off
for /F %%i in ('dir /b "c:\test directory\*.*"') do (
   echo Folder is NON empty
   goto :EOF
)
echo Folder is empty or does not exist

Taken from here.

That should do what you need.

In MVC _Layout.cshtml:

<base href="@Request.GetBaseUrl()" />

Thats what we use!

public static class ExtensionMethods
{
public static string GetBaseUrl(this HttpRequestBase request)
        {
          if (request.Url == (Uri) null)
            return string.Empty;
          else
            return request.Url.Scheme + "://" + request.Url.Authority + VirtualPathUtility.ToAbsolute("~/");
        }
}

When I used --allow-unrelated-histories, this command generated too many conflicts. There were conflicts in files which I didn't even work on. To get over the error " Refusing to merge unrelated histories", I used following rebase command:

git pull --rebase=preserve --allow-unrelated-histories

After this commit the uncommitted changes with a commit message. Finally, run the following command:

git rebase --continue

After this, my working copy was up-to-date with the remote copy and I was able to push my changes as before. No more unrelated histories error while pulling.

You need to anchor the regex at the start and end of the string:

^[0-9]+$

Explanation:

^      # Start of string
[0-9]+ # one or more digits 0-9
$      # End of string

As I understand it, you want the server be able to send messages through from client 1 to client 2. You cannot directly connect two clients because one of the two ends of a WebSocket connection needs to be a server.

This is some pseudocodish JavaScript:

Client:

var websocket = new WebSocket("server address");

websocket.onmessage = function(str) {
  console.log("Someone sent: ", str);
};

// Tell the server this is client 1 (swap for client 2 of course)
websocket.send(JSON.stringify({
  id: "client1"
}));

// Tell the server we want to send something to the other client
websocket.send(JSON.stringify({
  to: "client2",
  data: "foo"
}));

Server:

var clients = {};

server.on("data", function(client, str) {
  var obj = JSON.parse(str);

  if("id" in obj) {
    // New client, add it to the id/client object
    clients[obj.id] = client;
  } else {
    // Send data to the client requested
    clients[obj.to].send(obj.data);
  }
});

In addition to the provided answer, there are more details to navigate. From the function's comments:

/**
 * Navigate based on the provided array of commands and a starting point.
 * If no starting route is provided, the navigation is absolute.
 *
 * Returns a promise that:
 * - resolves to 'true' when navigation succeeds,
 * - resolves to 'false' when navigation fails,
 * - is rejected when an error happens.
 *
 * ### Usage
 *
 * ```
 * router.navigate(['team', 33, 'user', 11], {relativeTo: route});
 *
 * // Navigate without updating the URL
 * router.navigate(['team', 33, 'user', 11], {relativeTo: route, skipLocationChange: true});
 * ```
 *
 * In opposite to `navigateByUrl`, `navigate` always takes a delta that is applied to the current
 * URL.
 */

The Router Guide has more details on programmatic navigation.

we mainly use the markup notation of jquery validation plugin and the posted samples did not work for us, when flags are present in the regex, e.g.

<input type="text" name="myfield" regex="/^[0-9]{3}$/i" />

therefore we use the following snippet

$.validator.addMethod(
        "regex",
        function(value, element, regstring) {
            // fast exit on empty optional
            if (this.optional(element)) {
                return true;
            }

            var regParts = regstring.match(/^\/(.*?)\/([gim]*)$/);
            if (regParts) {
                // the parsed pattern had delimiters and modifiers. handle them. 
                var regexp = new RegExp(regParts[1], regParts[2]);
            } else {
                // we got pattern string without delimiters
                var regexp = new RegExp(regstring);
            }

            return regexp.test(value);
        },
        "Please check your input."
);  

Of course now one could combine this code, with one of the above to also allow passing RegExp objects into the plugin, but since we didn't needed it we left this exercise for the reader ;-).

PS: there is also bundled plugin for that, https://github.com/jzaefferer/jquery-validation/blob/master/src/additional/pattern.js

What have you tried? This should work.

h1 { font-size: 20pt; }
h2 { font-size: 16pt; }

The Directory.Delete method has a recursive boolean parameter, it should do what you need

You need to put your main code on the OnStart method.

This other SO answer of mine might help.

You will need to put some code to enable debugging within visual-studio while maintaining your application valid as a windows-service. This other SO thread cover the issue of debugging a windows-service.

EDIT:

Please see also the documentation available here for the OnStart method at the MSDN where one can read this:

Do not use the constructor to perform processing that should be in OnStart. Use OnStart to handle all initialization of your service. The constructor is called when the application's executable runs, not when the service runs. The executable runs before OnStart. When you continue, for example, the constructor is not called again because the SCM already holds the object in memory. If OnStop releases resources allocated in the constructor rather than in OnStart, the needed resources would not be created again the second time the service is called.

Based on http://dev.mysql.com/doc/refman/5.0/en/create-table-select.html

What about:

Create Table New_Users Select * from Old_Users Where 1=2;

and if that doesn't work, just select a row and truncate after creation:

Create table New_Users select * from Old_Users Limit 1;
Truncate Table New_Users;

EDIT:

I noticed your comment below about needing indexes, etc. Try:

show create table old_users;
#copy the output ddl statement into a text editor and change the table name to new_users
#run the new query
insert into new_users(id,name...) select id,name,... form old_users group by id;

That should do it. It appears that you are doing this to get rid of duplicates? In which case you may want to put a unique index on id. if it's a primary key, this should already be in place. You can either:

#make primary key
alter table new_users add primary key (id);
#make unique
create unique index idx_new_users_id_uniq on new_users (id);

Just try this:

Bitmap bitmap = BitmapFactory.decodeFile("/path/images/image.jpg");
ByteArrayOutputStream blob = new ByteArrayOutputStream();
bitmap.compress(CompressFormat.PNG, 0 /* Ignored for PNGs */, blob);
byte[] bitmapdata = blob.toByteArray();

If bitmapdata is the byte array then getting Bitmap is done like this:

Bitmap bitmap = BitmapFactory.decodeByteArray(bitmapdata, 0, bitmapdata.length);

Returns the decoded Bitmap, or null if the image could not be decoded.

I recommend you to read the following post: AngularJS: "Controller as" or "$scope"?

It describes very well the advantages of using "Controller as" to expose variables over "$scope".

I know you asked specifically about methods and not variables, but I think that it's better to stick to one technique and be consistent with it.

So for my opinion, because of the variables issue discussed in the post, it's better to just use the "Controller as" technique and also apply it to the methods.

Use the beforeSend callback to add a HTTP header with the authentication information like so:

var username = $("input#username").val();
var password = $("input#password").val();  

function make_base_auth(user, password) {
  var tok = user + ':' + password;
  var hash = btoa(tok);
  return "Basic " + hash;
}
$.ajax
  ({
    type: "GET",
    url: "index1.php",
    dataType: 'json',
    async: false,
    data: '{}',
    beforeSend: function (xhr){ 
        xhr.setRequestHeader('Authorization', make_base_auth(username, password)); 
    },
    success: function (){
        alert('Thanks for your comment!'); 
    }
});

     foreach (DataRow row in dt.Rows) 
     {
        foreach (DataColumn col in dt.Columns)
           Console.WriteLine(row[col]);
     }

do not make headaches for yourself, want a simple, one line solution to add a permanent environment variable (open powershell in elevated mode):

[Environment]::SetEnvironmentVariable("NewEnvVar", "NewEnvValue", "Machine")

close the session and open it again to make things done

in case that u want to modify/change that:

[Environment]::SetEnvironmentVariable("oldEnvVar", "NewEnvValue", "Machine")

in case that u want to delete/remove that:

[Environment]::SetEnvironmentVariable("oldEnvVar", "", "Machine")

Try adding animation-fill-mode: forwards;. For example like this:

-webkit-animation: bubble 1.0s forwards; /* for less modern browsers */
        animation: bubble 1.0s forwards;

1. Open 'Maven projects' (tab on the right side).
2. Use 'Add Maven Projects'
3. Find your pom.xml

try this, tested on windows platform and it works fine :

from selenium import webdriver
browser = webdriver.Chrome('C:\\Users\\yeivic\\Downloads\\chromedriver')
browser.fullscreen_window()
browser.get('http://google.com/')

My solution on Windows 10 was just to stop IIS (Internet Information Services).

for people new to this you can also use a callback for example:

In your service:

.factory('DataHandler',function ($http){

   var GetRandomArtists = function(data, callback){
     $http.post(URL, data).success(function (response) {
         callback(response);
      });
   } 
})

In your controller:

    DataHandler.GetRandomArtists(3, function(response){
      $scope.data.random_artists = response;
   });

If you need different column width, do this:

<tr>
    <td></td>
    <td></td>
    <td></td>
    <td></td>
    <td></td>
    <td></td>
    <td></td>
    <td></td>
    <td></td>
</tr>
<tr>
    <td colspan="9">
        <table>
            <tr>
                <td></td>
                <td></td>
                <td></td>
                <td></td>
            </tr>
        </table>
    </td>
</tr>

A regular expression will do the trick with very little code:

import re

...

if re.match("^[A-Za-z0-9_-]*$", my_little_string):
    # do something here

If the value type is already double, then update the value with $set command can not change the value type double to int when using NumberInt() or NumberLong() function. So, to Change the value type, it must update the whole record.

var re = db.data.find({"name": "zero"})
re['value']=NumberInt(0)
db.data.update({"name": "zero"}, re)

DataReader:

• Holds the connection open until you are finished (don't forget to close it!).
• Can typically only be iterated over once
• Is not as useful for updating back to the database

On the other hand, it:

• Only has one record in memory at a time rather than an entire result set (this can be HUGE)
• Is about as fast as you can get for that one iteration
• Allows you start processing results sooner (once the first record is available). For some query types this can also be a very big deal.

DataAdapter/DataSet

• Lets you close the connection as soon it's done loading data, and may even close it for you automatically
• All of the results are available in memory
• You can iterate over it as many times as you need, or even look up a specific record by index
• Has some built-in faculties for updating back to the database

At the cost of:

• Much higher memory use
• You wait until all the data is loaded before using any of it

So really it depends on what you're doing, but I tend to prefer a DataReader until I need something that's only supported by a dataset. SqlDataReader is perfect for the common data access case of binding to a read-only grid.

Current Answer

Visual Studio Code has excellent search and replace capabilities across files. It is extremely fast, supports regex and live preview before replacement.

Merge your tests into one giant test will work. To make the test method more readable, you can do something like

[TestMethod]
public void MyIntegratonTestLikeUnitTest()
{
    AssertScenarioA();

    AssertScenarioB();

    ....
}

private void AssertScenarioA()
{
     // Assert
}

private void AssertScenarioB()
{
     // Assert
}

Actually the issue you have suggests you probably should improve the testability of the implementation.

Your solution is correct, but there is some redundancy in your regex.
The similar result can also be obtained from the following regex:

^([A-Z]{3})$

The {3} indicates that the [A-Z] must appear exactly 3 times.

The easiest way in most situations is margin.

Where you can do :

button{
  margin: 13px 12px 12px 10px;
}

OR

button{
  margin: 13px;
}

The difference between relational and non-relational is exactly that. The relational database architecture provides with constraints objects such as primary keys, foreign keys, etc that allows one to tie two or more tables in a relation. This is good so that we normalize our tables which is to say split information about what the database represents into many different tables, once can keep the integrity of the data.

For example, say you have a series of table that houses information about an employee. You could not delete a record from a table without deleting all the records that pertain to such record from the other tables. In this way you implement data integrity. The non-relational database doesn't provide this constraints constructs that will allow you to implement data integrity.

Unless you don't implement this constraint in the front end application that is utilized to populate the databases' tables, you are implementing a mess that can be compared with the wild west.

If I have understood your question correctly you want to display one particular cell of your populated datatable? This what I used to display the given cell in my DataGrid.

var s  = dataGridView2.Rows[i].Cells[j].Value;
txt_Country.Text = s.ToString();

Hope this helps

The jQuery code to grab the data and display it on my webpage:

$(document).ready(function() {
var items = [];

$.getJSON('labOrders.json', function(json) {
  $.each(json.medications, function(index, orders) {
    $.each(this, function() {
        $.each(this, function() {
            items.push('<div class="row">'+this.name+"\t"+this.strength+"\t"+this.dose+"\t"+this.route+"\t"+this.sig+"\t"+this.pillCount+"\t"+this.refills+'</div>'+"\n");
        });
    });
  });

  $('<div>', {
    "class":'loaded',
    html:items.join('')
  }).appendTo("body");

});

});

There is no :unchecked pseudo class however if you use the :checked pseudo class and the sibling selector you can differentiate between both states. I believe all of the latest browsers support the :checked pseudo class, you can find more info from this resource: http://www.whatstyle.net/articles/18/pretty_form_controls_with_css

Your going to get better browser support with jquery... you can use a click function to detect when the click happens and if its checked or not, then you can add a class or remove a class as necessary...

Use

x=`cat -n <file> | grep <match> | awk '{print $1}'`

Here you will get the line number where the match occurred.

Now you can use the following command to print 100 lines

awk -v var="$x" 'NR>=var && NR<=var+100{print}' <file>

or you can use "sed" as well

sed -n "${x},${x+100}p" <file>

Sounds like you want a simple imagemap, I'd recommend to not make it more complex than it needs to be. Here's an article on how to improve imagemaps with svg. It's very easy to do clickable regions in svg itself, just add some <a> elements around the shapes you want to have clickable.

A couple of options if you need something more advanced:

• http://jqvmap.com/
• http://jvectormap.com/
• http://polymaps.org/

I would prefer:

try
{
    ...
}
catch (FooException fe){
   throw fe;
}
catch (Exception e)
{
    // Note: don't catch all exceptions like this unless you know what you
    // are doing.
    ...
}

For all those who are reading this but do not have problem with application.css and instead with their custom CSS classes e.g. admin.css, base.css etc.

Solution is to use as mentioned

bundle exec rake assets:precompile

And in stylesheets references just reference application.css

<%= stylesheet_link_tag    "application", :media => "all" %>

Since assets pipeline will precompile all of your stylesheets in application.css. This also happens in development so using any other references is wrong when using assets pipeline.

I would suggest hinterland extension.

In other answers I couldn't find the method for how to install it from pip, so this is how you install it.

First, install jupyter contrib nbextensions by running

pip install jupyter_contrib_nbextensions

Next install js and css file for jupyter by running

jupyter contrib nbextension install --user

and at the end run,

jupyter nbextension enable hinterland/hinterland

The output of last command will be

Enabling notebook extension hinterland/hinterland...
      - Validating: OK

You may checkout this library for the same purpose also:

http://angular-route-segment.com

It looks like what you are looking for, and it is much simpler to use than ui-router. From the demo site:

JS:

$routeSegmentProvider.

when('/section1',          's1.home').
when('/section1/:id',      's1.itemInfo.overview').
when('/section2',          's2').

segment('s1', {
    templateUrl: 'templates/section1.html',
    controller: MainCtrl}).
within().
    segment('home', {
        templateUrl: 'templates/section1/home.html'}).
    segment('itemInfo', {
        templateUrl: 'templates/section1/item.html',
        controller: Section1ItemCtrl,
        dependencies: ['id']}).
    within().
        segment('overview', {
            templateUrl: 'templates/section1/item/overview.html'}).

Top-level HTML:

<ul>
    <li ng-class="{active: $routeSegment.startsWith('s1')}">
        <a href="/section1">Section 1</a>
    </li>
    <li ng-class="{active: $routeSegment.startsWith('s2')}">
        <a href="/section2">Section 2</a>
    </li>
</ul>
<div id="contents" app-view-segment="0"></div>

Nested HTML:

<h4>Section 1</h4>
Section 1 contents.
<div app-view-segment="1"></div>

Wonderful answer! I needed to fill in the empty cells in a column where there were titles in cells that applied to the empty cells below until the next title cell.

I used your code above to develop the code that is below my example sheet here. I applied this code as a macro ctl/shft/D to rapidly run down the column copying the titles.

--- Example Spreadsheet ------------ Title1 is copied to rows 2 and 3; Title2 is copied to cells below it in rows 5 and 6. After the second run of the Macro the active cell is the Title3 cell.

 ' **row** **Column1**        **Column2**
 '    1     Title1         Data 1 for title 1
 '    2                    Data 2 for title 1
 '    3                    Data 3 for title 1
 '    4     Title2         Data 1 for title 2
 '    5                    Data 2 for title 2
 '    6                    Data 3 for title 2
 '    7   Title 3          Data 1 for title 3

----- CopyDown code ----------

Sub CopyDown()
Dim Lastrow As String, FirstRow As String, strtCell As Range
'
' CopyDown Macro
' Copies the current cell to any empty cells below it.   
'
' Keyboard Shortcut: Ctrl+Shift+D
'
    Set strtCell = ActiveCell
    FirstRow = strtCell.Address
' Lastrow is address of the *list* of empty cells
    Lastrow = Range(Selection, Selection.End(xlDown).Offset(-1, 0)).Address
'   MsgBox Lastrow
    Range(Lastrow).Formula = strtCell.Formula

    Range(Lastrow).End(xlDown).Select
 End Sub

What about using PRIOR,

so

SELECT id, parent_id, PRIOR name
   FROM tbl 
START WITH id = 1 
CONNECT BY PRIOR id = parent_id`

or if you want to get the root name

SELECT id, parent_id, CONNECT_BY_ROOT name
   FROM tbl 
START WITH id = 1 
CONNECT BY PRIOR id = parent_id

sizeof(source) returns sizeof a pointer as source is declared as char *. Correct way to use it is strlen(source).

Next:

printf("%s",source[i]); 

expects string. i.e %s expects string but you are iterating in a loop to print each character. Hence use %c.

However your way of accessing(iterating) a string using the index i is correct and hence there are no other issues in it.

Since you're passing in a reference type (a class) there is no need use ref because per default only a reference to the actual object is passed and therefore you always change the object behind the reference.

Example:

public void Foo()
{
    MyClass myObject = new MyClass();
    myObject.Name = "Dog";
    Bar(myObject);
    Console.WriteLine(myObject.Name); // Writes "Cat".
}

public void Bar(MyClass someObject)
{
    someObject.Name = "Cat";
}

As long you pass in a class you don't have to use ref if you want to change the object inside your method.

What Works:

string relativePath = "..\\bling.txt";
string baseDirectory = "C:\\blah\\";
string absolutePath = Path.GetFullPath(baseDirectory + relativePath);

(result: absolutePath="C:\bling.txt")

What doesn't work

string relativePath = "..\\bling.txt";
Uri baseAbsoluteUri = new Uri("C:\\blah\\");
string absolutePath = new Uri(baseAbsoluteUri, relativePath).AbsolutePath;

(result: absolutePath="C:/blah/bling.txt")

For a use case like this, it may be useful to use a string constant so it can be marshaled into a JSON string. In the following example, []Base{A,C,G,T} would get marshaled to ["adenine","cytosine","guanine","thymine"].

type Base string

const (
    A Base = "adenine"
    C      = "cytosine"
    G      = "guanine"
    T      = "thymine"
)

When using iota, the values get marshaled into integers. In the following example, []Base{A,C,G,T} would get marshaled to [0,1,2,3].

type Base int

const (
    A Base = iota
    C
    G
    T
)

Here's an example comparing both approaches:

https://play.golang.org/p/VvkcWvv-Tvj

Without quotes works for me:

<item name="android:textStyle">bold|italic</item>

Assuming SQL Server 2000, the following StackOverflow question should address your problem.

If using SQL Server 2005/2008, you can use the following code (taken from here):

select cast(replace(cast(myntext as nvarchar(max)),'find','replace') as ntext)
from myntexttable

In the case of a data warehouse-type system you can consider collecting no statistics at all, and relying on dynamic sampling (setting optimizer_dynamic_sampling to level 2 or above).

although I suggest to use youtube api or call new intent and make the system handle it (i.e. youtube app), here some code that can help you, it has a call to an hidden method because you can't pause and resume webview

import java.lang.reflect.Method;

import android.annotation.SuppressLint;
import android.os.Bundle;
import android.webkit.WebChromeClient;
import android.webkit.WebSettings;
import android.webkit.WebView;

import android.app.Activity;

@SuppressLint("SetJavaScriptEnabled")
public class MultimediaPlayer extends Activity
{
    private WebView mWebView;
    private boolean mIsPaused = false;

    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.webview);

        String media_url = VIDEO_URL;

        mWebView = (WebView) findViewById(R.id.webview);
        mWebView.setWebChromeClient(new WebChromeClient());

        WebSettings ws = mWebView.getSettings();
        ws.setBuiltInZoomControls(true);
        ws.setJavaScriptEnabled(true);

        mIsPaused = true;
        resumeBrowser();
        mWebView.loadUrl(media_url);
    }

    @Override
    protected void onPause()
    {
        pauseBrowser();
        super.onPause();
    }

    @Override
    protected void onResume()
    {
        resumeBrowser();
        super.onResume();
    }

    private void pauseBrowser()
    {
        if (!mIsPaused)
        {
            // pause flash and javascript etc
            callHiddenWebViewMethod(mWebView, "onPause");
            mWebView.pauseTimers();
            mIsPaused = true;
        }
    }

    private void resumeBrowser()
    {
        if (mIsPaused)
        {
            // resume flash and javascript etc
            callHiddenWebViewMethod(mWebView, "onResume");
            mWebView.resumeTimers();
            mIsPaused = false;
        }
    }

    private void callHiddenWebViewMethod(final WebView wv, final String name)
    {
        try
        {
            final Method method = WebView.class.getMethod(name);
            method.invoke(mWebView);
        } catch (final Exception e)
        {}
    }
}

You can do this:

DECLARE @maxval TINYINT, @minval TINYINT
select @maxval=24,@minval=5

SELECT CAST(((@maxval + 1) - @minval) *
    RAND(CHECKSUM(NEWID())) + @minval AS TINYINT)

And that was taken directly from this link, I don't really know how to give proper credit for this answer.

That cannot be done in excel 2007. The list must be in the same sheet as your data. It might work in later versions though.

I ran into this as well, but in the case where I wanted to avoid the extra error messages while keeping the range provided. An option is also to subset the data prior to setting the range, so that the range can be kept however you like without triggering warnings.

library(ggplot2)

range(mtcars$hp)
#> [1]  52 335

# Setting limits with scale_y_continous (or ylim) and subsetting accordingly
## avoid warning messages about removing data
ggplot(data= subset(mtcars, hp<=300 & hp >= 100), aes(mpg, hp)) + 
  geom_point() +
  scale_y_continuous(limits=c(100,300))

You will have to read in all the data from the Stream object into a byte[] buffer and then pass that into the MemoryStream via its constructor. It may be better to be more specific about the type of stream object you are using. Stream is very generic and may not implement the Length attribute, which is rather useful when reading in data.

Here's some code for you:

public MyClass(Stream inputStream) {
    byte[] inputBuffer = new byte[inputStream.Length];
    inputStream.Read(inputBuffer, 0, inputBuffer.Length);

    _ms = new MemoryStream(inputBuffer);
}

If the Stream object doesn't implement the Length attribute, you will have to implement something like this:

public MyClass(Stream inputStream) {
    MemoryStream outputStream = new MemoryStream();

    byte[] inputBuffer = new byte[65535];
    int readAmount;
    while((readAmount = inputStream.Read(inputBuffer, 0, inputBuffer.Length)) > 0)
        outputStream.Write(inputBuffer, 0, readAmount);

    _ms = outputStream;
}

The Request.Form.Keys collection will be empty if none of your html inputs have NAMEs. It's easy to forget to put them there after you've been doing .NET for a while. Just name them and you'll be good to go.

Note that this may also work:

SELECT * FROM table WHERE s=ANY(array)

For me the solution was removing the following lines from my web.config file:

<dependentAssembly>
    <assemblyIdentity name="System.Net.Http" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-4.1.1.3" newVersion="4.1.1.3" />
</dependentAssembly>
<dependentAssembly>
    <assemblyIdentity name="Microsoft.IdentityModel.Tokens" publicKeyToken="31bf3856ad364e35" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-5.5.0.0" newVersion="5.5.0.0" />
</dependentAssembly>

I noticed that VS had added them automatically, not sure why

Create a class and give it an __init__ method:

class Student:
    def __init__(self, name, age, major):
        self.name = name
        self.age = age
        self.major = major

    def is_old(self):
        return self.age > 100

Now, you can initialize an instance of the Student class:

>>> s = Student('John', 88, None)
>>> s.name
    'John'
>>> s.age
    88

Although I'm not sure why you need a make_student student function if it does the same thing as Student.__init__.

This is more a workaround than a real solution. You can create a new object test_data with another column name:

left_join("names<-"(test_data, "name"), kantrowitz, by = "name")

     name gender
1    john      M
2    bill either
3 madison      M
4    abby either
5     zzz   <NA>

def prepare_table_row(row):
    lst = [i.text for i in row if i != u'\n']
    return dict(rank = int(lst[0]),
                grade = str(lst[1]),
                channel=str(lst[2])),
                videos = float(lst[3].replace(",", " ")),
                subscribers = float(lst[4].replace(",", "")),
                views = float(lst[5].replace(",", "")))

For just plotting a vector, you should use the following command:

text(your.vector, labels=your.labels, cex= labels.size, pos=labels.position)

ExtJS has a ComboBox control that can do this (and a whole host of other cool stuff!!)

EDIT: Browse all controls etc, here: http://www.sencha.com/products/js/

As a couple of answers have pointed out, I believe there is some some misunderstanding of multi tier vs MVC architecture.

Multi tier architecture involves breaking your application into tiers/layers (e.g. presentation, business logic, data access)

MVC is an architectural style for the presentation layer of an application. For non trivial applications, business logic/business rules/data access should not be placed directly into Models, Views, or Controllers. To do so would be placing business logic in your presentation layer and thus reducing reuse and maintainability of your code.

The model is a very reasonable choice choice to place business logic, but a better/more maintainable approach is to separate your presentation layer from your business logic layer and create a business logic layer and simply call the business logic layer from your models when needed. The business logic layer will in turn call into the data access layer.

I would like to point out that it is not uncommon to find code that mixes business logic and data access in one of the MVC components, especially if the application was not architected using multiple tiers. However, in most enterprise applications, you will commonly find multi tier architectures with an MVC architecture in place within the presentation layer.

It also important to make sure that the web server sends the file with Content-Disposition = inline. this might not be the case if you are reading the file yourself and send it's content to the browser:

in php it will look like this...

...headers...
header("Content-Disposition: inline; filename=doc.pdf");
...headers...

readfile('localfilepath.pdf')

Combining code from ISL 9.6.3 ROC Curves, along with @J. Won.'s answer to this question and a few more places, the following plots the ROC curve and prints the AUC in the bottom right on the plot.

Below probs is a numeric vector of predicted probabilities for binary classification and test$label contains the true labels of the test data.

require(ROCR)
require(pROC)

rocplot <- function(pred, truth, ...) {
  predob = prediction(pred, truth)
  perf = performance(predob, "tpr", "fpr")
  plot(perf, ...)
  area <- auc(truth, pred)
  area <- format(round(area, 4), nsmall = 4)
  text(x=0.8, y=0.1, labels = paste("AUC =", area))

  # the reference x=y line
  segments(x0=0, y0=0, x1=1, y1=1, col="gray", lty=2)
}

rocplot(probs, test$label, col="blue")

This gives a plot like this:

Try doing a sudo apt-get install libc6-dev.

apt-file tells me that the file in question belongs to that package.

For example a sha-1 digest calculation (change SHA-1 to MD5 to get MD5 digest)

HashCode hc = Files.asByteSource(file).hash(Hashing.sha1());
"SHA-1: " + hc.toString();

Note that crc32 is much faster than md5, so use crc32 if you do not need a cryptographically secure checksum. Note also that md5 should not be used to store passwords and the like since it is to easy to brute force, for passwords use bcrypt, scrypt or sha-256 instead.

For long term protection with hashes a Merkle signature scheme adds to the security and The Post Quantum Cryptography Study Group sponsored by the European Commission has recommended use of this cryptography for long term protection against quantum computers (ref).

Note that crc32 has a higher collision rate than the others.

Use multibranch pipeline job type, not the plain pipeline job type. The multibranch pipeline jobs do posess the environment variable env.BRANCH_NAME which describes the branch.

In my script..

stage('Build') {
    node {
        echo 'Pulling...' + env.BRANCH_NAME
        checkout scm
        
    }
}

Yields...

Pulling...master

You often will want to examine the particular properties of an instance of an object, without all of it's shared prototype methods and properties:

 Obj.prototype.toString= function(){
        var A= [];
        for(var p in this){
            if(this.hasOwnProperty(p)){
                A[A.length]= p+'='+this[p];
            }
        }

    return A.join(', ');
}

For the equivalent of NVL() and ISNULL() use:

IFNULL(column, altValue)

column : The column you are evaluating.

altValue : The value you want to return if 'column' is null.

Example:

SELECT IFNULL(middle_name, 'N/A') FROM person;

*Note: The COALESCE() function works the same as it does for other databases.

Just Change in build.gradle file

 classpath 'com.android.tools.build:gradle:1.3.0'

To

 classpath 'com.android.tools.build:gradle:2.0.0'

1. Now GoTo -> menu choose File -> Invalidate Caches/Restart...

2. Choose first option: Invalidate and Restart

   Android Studio would restart.

   After this, it should work normally.

I came up with this:

int counter = 0;

bool checkPrime(int x) {
   for (int y = x; y > 0; y--){
      if (x%y == 0) {
         counter++;
      }
   }
   if (counter == 2) {
      counter = 0; //resets counter for next input
      return true; //if its only divisible by two numbers (itself and one) its a prime
   }
   else counter = 0;
        return false;
}

update these in gradle

compileSdkVersion 27 buildToolsVersion '27.0.1'

Here is how I would do it:

bool intersects(CircleType circle, RectType rect)
{
    circleDistance.x = abs(circle.x - rect.x);
    circleDistance.y = abs(circle.y - rect.y);

    if (circleDistance.x > (rect.width/2 + circle.r)) { return false; }
    if (circleDistance.y > (rect.height/2 + circle.r)) { return false; }

    if (circleDistance.x <= (rect.width/2)) { return true; } 
    if (circleDistance.y <= (rect.height/2)) { return true; }

    cornerDistance_sq = (circleDistance.x - rect.width/2)^2 +
                         (circleDistance.y - rect.height/2)^2;

    return (cornerDistance_sq <= (circle.r^2));
}

Here's how it works:

1. The first pair of lines calculate the absolute values of the x and y difference between the center of the circle and the center of the rectangle. This collapses the four quadrants down into one, so that the calculations do not have to be done four times. The image shows the area in which the center of the circle must now lie. Note that only the single quadrant is shown. The rectangle is the grey area, and the red border outlines the critical area which is exactly one radius away from the edges of the rectangle. The center of the circle has to be within this red border for the intersection to occur.

2. The second pair of lines eliminate the easy cases where the circle is far enough away from the rectangle (in either direction) that no intersection is possible. This corresponds to the green area in the image.

3. The third pair of lines handle the easy cases where the circle is close enough to the rectangle (in either direction) that an intersection is guaranteed. This corresponds to the orange and grey sections in the image. Note that this step must be done after step 2 for the logic to make sense.

4. The remaining lines calculate the difficult case where the circle may intersect the corner of the rectangle. To solve, compute the distance from the center of the circle and the corner, and then verify that the distance is not more than the radius of the circle. This calculation returns false for all circles whose center is within the red shaded area and returns true for all circles whose center is within the white shaded area.

A great alternative that hasn't been mentioned is to use the entity framework, which uses an object that is the table - to get data into an array you can do things like:

var rows = db.someTable.SqlQuery("SELECT col1,col2 FROM  someTable").ToList().ToArray();

for info on getting started with Entity Framework see https://msdn.microsoft.com/en-us/library/aa937723(v=vs.113).aspx

Step 1: Create a new resource file in drawable and copy paste

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

    <stroke android:color="#fff" android:width="2dp"/>
    <corners android:radius="25dp"/>
    <padding android:right="15dp" android:top="15dp" android:bottom="15dp" android:left="15dp"/>
</shape>

save it as ButtonUI(let's say)

Step 2: Apply the UI to the button xml

<Button
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:text="join the crew"
  android:background="@drawable/ButtonUI"
  android:textColor="#fff"/>

The R packages dplyr and sf import the operator %>% from the R package magrittr.

Help is available by using the following command:

?'%>%'

Of course the package must be loaded before by using e.g.

library(sf)

The documentation of the magrittr forward-pipe operator gives a good example: When functions require only one argument, x %>% f is equivalent to f(x)

Use [NSIndexPath indexPathForRow:inSection:] to quickly create an index path.

from collections import OrderedDict
from operator import itemgetter    

d = {"aa": 3, "bb": 4, "cc": 2, "dd": 1}
print(OrderedDict(sorted(d.items(), key = itemgetter(1), reverse = True)))

prints

OrderedDict([('bb', 4), ('aa', 3), ('cc', 2), ('dd', 1)])

Though from your last sentence, it appears that a list of tuples would work just fine, e.g.

from operator import itemgetter  

d = {"aa": 3, "bb": 4, "cc": 2, "dd": 1}
for key, value in sorted(d.items(), key = itemgetter(1), reverse = True):
    print(key, value)

which prints

bb 4
aa 3
cc 2
dd 1

You can use Jasypt

With Jasypt, encrypting and checking a password can be as simple as...

StrongTextEncryptor textEncryptor = new StrongTextEncryptor();
textEncryptor.setPassword(myEncryptionPassword);

Encryption:

String myEncryptedText = textEncryptor.encrypt(myText);

Decryption:

String plainText = textEncryptor.decrypt(myEncryptedText);

Gradle:

compile group: 'org.jasypt', name: 'jasypt', version: '1.9.2'

Features:

Jasypt provides you with easy unidirectional (digest) and bidirectional encryption techniques.

Open API for use with any JCE provider, and not only the default Java VM one. Jasypt can be easily used with well-known providers like Bouncy Castle. Learn more.

Higher security for your users' passwords. Learn more.

Binary encryption support. Jasypt allows the digest and encryption of binaries (byte arrays). Encrypt your objects or files when needed (for being sent over the net, for example).

Number encryption support. Besides texts and binaries, it allows the digest and encryption of numeric values (BigInteger and BigDecimal, other numeric types are supported when encrypting for Hibernate persistence). Learn more.

Completely thread-safe.

Support for encryptor/digester pooling, in order to achieve high performance in multi-processor/multi-core systems.

Includes a lightweight ("lite") version of the library for better manageability in size-restrictive environments like mobile platforms.

Provides both easy, no-configuration encryption tools for users new to encryption, and also highly configurable standard encryption tools, for power-users.

Hibernate 3 and 4 optional integration for persisting fields of your mapped entities in an encrypted manner. Encryption of fields is defined in the Hibernate mapping files, and it remains transparent for the rest of the application (useful for sensitive personal data, databases with many read-enabled users...). Encrypt texts, binaries, numbers, booleans, dates... Learn more.

Seamlessly integrable into a Spring application, with specific integration features for Spring 2, Spring 3.0 and Spring 3.1. All the digesters and encryptors in jasypt are designed to be easily used (instantiated, dependency-injected...) from Spring. And, because of their being thread-safe, they can be used without synchronization worries in a singleton-oriented environment like Spring. Learn more: Spring 2, Spring 3.0, Spring 3.1.

Spring Security (formerly Acegi Security) optional integration for performing password encryption and matching tasks for the security framework, improving the security of your users' passwords by using safer password encryption mechanisms and providing you with a higher degree of configuration and control. Learn more.

Provides advanced functionality for encrypting all or part of an application's configuration files, including sensitive information like database passwords. Seamlessly integrate encrypted configuration into plain, Spring-based and/or Hibernate-enabled applications. Learn more.

Provides easy to use CLI (Command Line Interface) tools to allow developers initialise their encrypted data and include encryption/decryption/digest operations in maintenance tasks or scripts. Learn more.

Integrates into Apache Wicket, for more robust encryption of URLs in your secure applications.

Comprehensive guides and javadoc documentation, to allow developers to better understand what they are really doing to their data.

Robust charset support, designed to adequately encrypt and digest texts whichever the original charset is. Complete support for languages like Japanese, Korean, Arabic... with no encoding or platform issues.

Very high level of configuration capabilities: The developer can implement tricks like instructing an "encryptor" to ask a, for example, remote HTTPS server for the password to be used for encryption. It lets you meet your security needs.

Ensure you are editing the correct configuration file for VIM. Especially if you are using windows, where the file could be named _vimrc instead of .vimrc as on other platforms.

In vim type

:help vimrc

and check your path to the _vimrc/.vimrc file with

:echo $HOME

:echo $VIM

Make sure you are only using one file. If you want to split your configuration into smaller chunks you can source other files from inside your _vimrc file.

:help source

Use

// MARK: SectionName

or

// MARK: - SectionName

This will give a line above pragma mark, making it more readable.

For ease just add

// MARK: - <#label#>

to your code snippets.

Alternate way -

Use it in this way

private typealias SectionName = ViewController
private extension SectionName  {
    // Your methods
}

This will not only add mark(just like pragma mark) but also segregate the code nicely.

The problem is that the 'and' is being treated as an 'or'.

No, the problem is that you are using the XPath != operator and you aren't aware of its "weird" semantics.

Solution:

Just replace the any x != y expressions with a not(x = y) expression.

In your specific case:

Replace:

<xsl:when test="$AccountNumber != '12345' and $Balance != '0'">

with:

<xsl:when test="not($AccountNumber = '12345') and not($Balance = '0')">

Explanation:

By definition whenever one of the operands of the != operator is a nodeset, then the result of evaluating this operator is true if there is a node in the node-set, whose value isn't equal to the other operand.

So:

 $someNodeSet != $someValue

generally doesn't produce the same result as:

 not($someNodeSet = $someValue)

The latter (by definition) is true exactly when there isn't a node in $someNodeSet whose string value is equal to $someValue.

Lesson to learn:

Never use the != operator, unless you are absolutely sure you know what you are doing.

How I load Icons: Using Visual Studio 2010: Go to the project properties, click Add Resource > Existing File, select your Icon.

You'll see that a Resources folder appeared. This was my problem, I had to click the loaded icon (in Resources directory), and set "Copy to Output Directory" to "Copy always". (was set "Do not copy").

Now simply do:

Icon myIcon = new Icon("Resources/myIcon.ico");

Html.Partial returns a String. Html.RenderPartial calls Write internally and returns void.

The basic usage is:

// Razor syntax
@Html.Partial("ViewName")
@{ Html.RenderPartial("ViewName");  }

// WebView syntax
<%: Html.Partial("ViewName") %>
<% Html.RenderPartial("ViewName"); %>

In the snippet above, both calls will yield the same result.

While one can store the output of Html.Partial in a variable or return it from a method, one cannot do this with Html.RenderPartial.

The result will be written to the Response stream during execution/evaluation.

This also applies to Html.Action and Html.RenderAction.

The second of the two methods here does what you're wanting. I've just used it (after finding no success in this thread) and it's worked for me.

http://yorch.org/2011/10/two-ways-to-check-if-a-registry-key-exists-using-vbscript/

The code:

Const HKCR = &H80000000 'HKEY_CLASSES_ROOT
Const HKCU = &H80000001 'HKEY_CURRENT_USER
Const HKLM = &H80000002 'HKEY_LOCAL_MACHINE
Const HKUS = &H80000003 'HKEY_USERS
Const HKCC = &H80000005 'HKEY_CURRENT_CONFIG

Function KeyExists(Key, KeyPath)
    Dim oReg: Set oReg = GetObject("winmgmts:!root/default:StdRegProv")
    If oReg.EnumKey(Key, KeyPath, arrSubKeys) = 0 Then
        KeyExists = True
    Else
        KeyExists = False
   End If
End Function

Changing keystore password

$ keytool -storepasswd -keystore keystorename
Enter keystore password:  <old password>
New keystore password: <new password>
Re-enter new keystore password: <new password>

Changing keystore alias password

$keytool -keypasswd -keystore keystorename -alias aliasname
Enter keystore password:  
New key password for <aliasname>: 
Re-enter new key password for <aliasname>:

Note:

**Keystorename**: name of your keystore(with path if you are indifferent folder) 
**aliasname**: alias name you used when creating (if name has space you can use \) 
for example: $keytool -keypasswd -keystore keystorename -alias stop\ watch

The solution to keep the large files/folders within the working folder

This is the line that worked to solve the problem asked here (from answer 1):

git filter-branch --index-filter 'git rm -r --cached --ignore-unmatch <file/dir>' HEAD

This command also delete the file/dir if the file/dir is within the working tree.

If you want to keep the file/folder within the working tree I propose taking the following steps.

1. After that error run git reset HEAD^

2. Add the file/folder in question into ``.gitignore``` file.

3. Proceed as usual git add . which might capture other files/folders but must capture .gitignore file. Next is git commit -m"message" and finally git push origin <branch_name>

Just do:

echo substr($string, 0, -3);

You don't need to use a strlen call, since, as noted in the substr docs:

If length is given and is negative, then that many characters will be omitted from the end of string

Rather than using aliases, I prefer creating git-XXX scripts so I can source control them more easily (our devs all have a certain source controlled dir on their path for this type of thing).

This script (called git-setpush) will set the config value for remote.origin.push value to something that will only push the current branch:

#!/bin/bash -eu

CURRENT_BRANCH=$(git branch | grep '^\*' | cut -d" " -f2)
NEW_PUSH_REF=HEAD:refs/for/$CURRENT_BRANCH

echo "setting remote.origin.push to $NEW_PUSH_REF"
git config remote.origin.push $NEW_PUSH_REF

note, as we're using Gerrit, it sets the target to refs/for/XXX to push into a review branch. It also assumes origin is your remote name.

Invoke it after checking out a branch with

git checkout your-branch
git setpush

It could obviously be adapted to also do the checkout, but I like scripts to do one thing and do it well

LPCWSTR is equivalent to wchar_t const *. It's a pointer to a wide character string that won't be modified by the function call.

You can assign to LPCWSTRs by prepending a L to a string literal: LPCWSTR *myStr = L"Hello World";

LPCTSTR and any other T types, take a string type depending on the Unicode settings for your project. If _UNICODE is defined for your project, the use of T types is the same as the wide character forms, otherwise the Ansi forms. The appropriate function will also be called this way: FindWindowEx is defined as FindWindowExA or FindWindowExW depending on this definition.

A note for using Docker Windows containers after I had to look for this problem for a long time!

Condiditions:

• Windows 10
• Docker Desktop (latest version)
• using Docker Windows Container for image microsoft/mssql-server-windows-developer

Problem:

• I wanted to mount a host dictionary into my windows container.

Solution as partially discripted here:

• create docker container

docker run -d -p 1433:1433 -e sa_password=<STRONG_PASSWORD> -e ACCEPT_EULA=Y microsoft/mssql-server-windows-developer

• go to command shell in container

docker exec -it <CONTAINERID> cmd.exe

• create DIR

mkdir DirForMount

• stop container

docker container stop <CONTAINERID>

• commit container

docker commit <CONTAINERID> <NEWIMAGENAME>

• delete old container

docker container rm <CONTAINERID>

• create new container with new image and volume mounting

docker run -d -p 1433:1433 -e sa_password=<STRONG_PASSWORD> -e ACCEPT_EULA=Y -v C:\DirToMount:C:\DirForMount <NEWIMAGENAME>

After this i solved this problem on docker windows containers.

It's not open source, but you can at least get a free personal use license to Prince, which really does a lovely job.

Another way besides @Nahush's answer, if you are already using Express framework in the project then you can avoid using Nginx for reverse-proxy.

A simpler way is to use express-http-proxy

1. run npm run build to create the bundle.

   var proxy = require('express-http-proxy');
   
   var app = require('express')();
   
   //define the path of build
   
   var staticFilesPath = path.resolve(__dirname, '..', 'build');
   
   app.use(express.static(staticFilesPath));
   
   app.use('/api/api-server', proxy('www.api-server.com'));
   

Use "/api/api-server" from react code to call the API.

So, that browser will send request to the same host which will be internally redirecting the request to another server and the browser will feel that It is coming from the same origin ;)

The systemd way to do this is to have the process "talk back" when it's setup somehow, like by opening a socket or sending a notification (or a parent script exiting). Which is of course not always straight-forward especially with third party stuff :|

You might be able to do something inline like

ExecStart=/bin/bash -c '/bin/start_cassandra &; do_bash_loop_waiting_for_it_to_come_up_here'

or a script that does the same. Or put do_bash_loop_waiting_for_it_to_come_up_here in an ExecStartPost

Or create a helper .service that waits for it to come up, so the helper service depends on cassandra, and waits for it to come up, then your other process can depend on the helper service.

(May want to increase TimeoutStartSec from the default 90s as well)

I've found solution here. In my case element becomes inaccessible in case of leaving current window, tab or page and coming back again.

.ignoring(StaleElement...), .refreshed(...) and elementToBeClicable(...) did not help and I was getting exception on act.doubleClick(element).build().perform(); string.

Using function in my main test class:

openForm(someXpath);

My BaseTest function:

int defaultTime = 15;

boolean openForm(String myXpath) throws Exception {
    int count = 0;
    boolean clicked = false;
    while (count < 4 || !clicked) {
        try {
            WebElement element = getWebElClickable(myXpath,defaultTime);
            act.doubleClick(element).build().perform();
            clicked = true;
            print("Element have been clicked!");
            break;
        } catch (StaleElementReferenceException sere) {
            sere.toString();
            print("Trying to recover from: "+sere.getMessage());
            count=count+1;
        }
    }

My BaseClass function:

protected WebElement getWebElClickable(String xpath, int waitSeconds) {
        wait = new WebDriverWait(driver, waitSeconds);
        return wait.ignoring(StaleElementReferenceException.class).until(
                ExpectedConditions.refreshed(ExpectedConditions.elementToBeClickable(By.xpath(xpath))));
    }

As of 2016, you can do this more simply than in any of the answers already given:

$('#myChosenBox').val();

where "myChosenBox" is the id of the original select input. Or, in the change event:

$('#myChosenBox').on('change', function(e, params) {
    alert(e.target.value); // OR
    alert(this.value); // OR
    alert(params.selected); // also in Panagiotis Kousaris' answer
}

In the Chosen doc, in the section near the bottom of the page on triggering events, it says "Chosen triggers a number of standard and custom events on the original select field." One of those standard events is the change event, so you can use it in the same way as you would with a standard select input. You don't have to mess around with using Chosen's applied classes as selectors if you don't want to. (For the change event, that is. Other events are often a different matter.)

to sum it up

1) in AndroidStudio's settings > compile enable checkbox named Compile independent modules in parallel.

2) Under Help> Edit Custom VM Options I have:

-Xms1024m 
-Xmx4096m # <------ increase this to most of your RAM 
-XX:MaxPermSize=1024m 
-XX:ReservedCodeCacheSize=440m 
-XX:+UseCompressedOops 
-XX:-HeapDumpOnOutOfMemoryError 
-Dfile.encoding=UTF-8

P.S. - Some people say Note, instead of VM options, it's better to combine can be overriden by combining those lines into one line single command in gradle.properties, like this :

org.gradle.jvmargs=-Xms1024m -Xmx4096m ......

3) I have an old dual core with 4GB ram, running ubuntu. Qs command line option I have only --offline (which specifies that the build should operate without accessing network resources). I also enabled the remaining checkboxes and now it's running ok:

• Make project automatically

• Use in-process building Configure on demand

• Check the AndroidStudio's settings, under compile that the checkbox Compile independent modules in parallel is enabled.

Under Vmoptions I have

-Xmx2048m -XX:MaxPermSize=1024

I have an old dual core with 4GB ram, running ubuntu. Qs commandline option I have only --offline , which specifies that the build should operate without accessing network resources. I enabled also the remaining checkboxes:

1. Make project automatically
2. Use in-process building

3. Configure on demand

   and it is running ok

Edit

It is possible to provide additional options through studio.vmoptions located at (just replace X.X with version):

• Windows: go to %USERPROFILE%\.AndroidStudioX.X\studio.exe.vmoptions (or studio64.exe.vmoptions)

• Mac: ~/Library/Preferences/.AndroidStudioX.X/studio.vmoptions

• Linux: ~/.AndroidStudioX.X/studio.vmoptions (and/or studio64.vmoptions)

Increasing the value of -Xmx should help a lot. E.g

-Xms1024m
-Xmx4096m
-XX:MaxPermSize=1024m
-XX:ReservedCodeCacheSize=256m
-XX:+UseCompressedOops

will assign 4G as max heap, with initial value of 1G

Edit:

On windows the defaults are stored into C:\Program Files\Android\Android Studio\bin\*.vmoptions. The IDE allows you to tweak those values through Help->Edit Custom VM options (thanks to @Code-Read for pointing it out).

EDIT 2:

Android studio 3.5 makes easier to change same of those values. Just go to:

Good that you've managed to get it working with the html5 mode but it is also possible to make it work in the hashbang mode.

You could simply use:

$location.search().target

to get access to the 'target' search param.

The code you've already tried:

document.getElementById("gift-close").click();

...should work as long as the element actually exists in the DOM at the time you run it. Some possible ways to ensure that include:

1. Run your code from an onload handler for the window. http://jsfiddle.net/LKNYg/
2. Run your code from a document ready handler if you're using jQuery. http://jsfiddle.net/LKNYg/1/
3. Put the code in a script block that is after the element in the source html.

So:

$(document).ready(function() {
    document.getElementById("gift-close").click();
    // OR
    $("#gift-close")[0].click();
});

To make my future me happy: RTFM - don't use the gitlab-ci-token at all, but the .netrc file.

There are a couple of important points:

1. echo -e "machine gitlab.com\nlogin gitlab-ci-token\npassword ${CI_JOB_TOKEN}" > ~/.netrc
2. Don't forget to replace "gitlab.com" by your URL!
3. Don't try to be smart and create the .netrc file directly - gitlab will not replace the $CI_JOB_TOKEN within the file!
4. Use https://gitlab.com/whatever/foobar.com - not ssh://git@foobar, not git+ssh://, not git+https://. You also don't need any CI-TOKEN stuff in the URL.
5. Make sure you can git clone [url from step 4]

Background: I got

fatal: could not read Username for 'https://gitlab.mycompany.com': No such device or address

when I tried to make Ansible + Gitlab + Docker work as I imagine it. Now it works.

It's just an addition, with this you can get the data into CSV format

import sys,os
try:
    import pandas as pd
except:
    os.system("pip3 install pandas")
    
root = "/home/kiran/Downloads/MainFolder" # it may have many subfolders and files inside
lst = []
from fnmatch import fnmatch
pattern = "*.csv"      #I want to get only csv files 
pattern = "*.*"        # Note: Use this pattern to get all types of files and folders 
for path, subdirs, files in os.walk(root):
    for name in files:
        if fnmatch(name, pattern):
            lst.append((os.path.join(path, name)))
df = pd.DataFrame({"filePaths":lst})
df.to_csv("filepaths.csv")

Python can do unexpected things when new objects are defined from existing ones. You stated in a comment above that your dataframe is defined along the lines of df = df_all.loc[df_all['issueid']==specific_id,:]. In this case, df is really just a stand-in for the rows stored in the df_all object: a new object is NOT created in memory.

To avoid these issues altogether, I often have to remind myself to use the copy module, which explicitly forces objects to be copied in memory so that methods called on the new objects are not applied to the source object. I had the same problem as you, and avoided it using the deepcopy function.

In your case, this should get rid of the warning message:

from copy import deepcopy
df = deepcopy(df_all.loc[df_all['issueid']==specific_id,:])
df['industry'] = 'yyy'

EDIT: Also see David M.'s excellent comment below!

df = df_all.loc[df_all['issueid']==specific_id,:].copy()
df['industry'] = 'yyy'

They are two different metrics to evaluate your model's performance usually being used in different phases.

Loss is often used in the training process to find the "best" parameter values for your model (e.g. weights in neural network). It is what you try to optimize in the training by updating weights.

Accuracy is more from an applied perspective. Once you find the optimized parameters above, you use this metrics to evaluate how accurate your model's prediction is compared to the true data.

Let us use a toy classification example. You want to predict gender from one's weight and height. You have 3 data, they are as follows:(0 stands for male, 1 stands for female)

y1 = 0, x1_w = 50kg, x2_h = 160cm;

y2 = 0, x2_w = 60kg, x2_h = 170cm;

y3 = 1, x3_w = 55kg, x3_h = 175cm;

You use a simple logistic regression model that is y = 1/(1+exp-(b1*x_w+b2*x_h))

How do you find b1 and b2? you define a loss first and use optimization method to minimize the loss in an iterative way by updating b1 and b2.

In our example, a typical loss for this binary classification problem can be: (a minus sign should be added in front of the summation sign)

We don't know what b1 and b2 should be. Let us make a random guess say b1 = 0.1 and b2 = -0.03. Then what is our loss now?

so the loss is

Then you learning algorithm (e.g. gradient descent) will find a way to update b1 and b2 to decrease the loss.

What if b1=0.1 and b2=-0.03 is the final b1 and b2 (output from gradient descent), what is the accuracy now?

Let's assume if y_hat >= 0.5, we decide our prediction is female(1). otherwise it would be 0. Therefore, our algorithm predict y1 = 1, y2 = 1 and y3 = 1. What is our accuracy? We make wrong prediction on y1 and y2 and make correct one on y3. So now our accuracy is 1/3 = 33.33%

PS: In Amir's answer, back-propagation is said to be an optimization method in NN. I think it would be treated as a way to find gradient for weights in NN. Common optimization method in NN are GradientDescent and Adam.

Here is a manual way to do git remote set-url origin [new repo URL]:

1. Clone the repository: git clone <old remote>
2. Create a GitHub repository

3. Open <repository>/.git/config

   $ git config -e
   

   [core]
       repositoryformatversion = 0
       filemode = false
       bare = false
       logallrefupdates = true
       symlinks = false
       ignorecase = true
   [remote "origin"]
       url = <old remote>
       fetch = +refs/heads/*:refs/remotes/origin/*
   [branch "master"]
       remote = origin
       merge = refs/heads/master
   

   and change the remote (the url option)

   [remote "origin"]
       url = <new remote>
       fetch = +refs/heads/*:refs/remotes/origin/*
   

4. Push the repository to GitHub: git push

You can also use both/multiple remotes.
