In the CMakeLists.txt file, create a cache variable, as documented here:

SET(FAB "po" CACHE STRING "Some user-specified option")

Source: http://cmake.org/cmake/help/v2.8.8/cmake.html#command:set

Then, either use the GUI (ccmake or cmake-gui) to set the cache variable, or specify the value of the variable on the cmake command line:

cmake -DFAB:STRING=po

Source: http://cmake.org/cmake/help/v2.8.8/cmake.html#opt:-Dvar:typevalue

Modify your cache variable to a boolean if, in fact, your option is boolean.

This path worked for me. on a 32 bit machine.

Should a person find themselves reading this QA while they are trying to ssh into a NetGear ReadyNAS device, be sure that the "rsync only" checkbox is unchecked in the dialog box for the ssh service in the admin interface.

I used the action delegate like this in a project once:

private static Dictionary<Type, Action<Control>> controldefaults = new Dictionary<Type, Action<Control>>() { 
            {typeof(TextBox), c => ((TextBox)c).Clear()},
            {typeof(CheckBox), c => ((CheckBox)c).Checked = false},
            {typeof(ListBox), c => ((ListBox)c).Items.Clear()},
            {typeof(RadioButton), c => ((RadioButton)c).Checked = false},
            {typeof(GroupBox), c => ((GroupBox)c).Controls.ClearControls()},
            {typeof(Panel), c => ((Panel)c).Controls.ClearControls()}
    };

which all it does is store a action(method call) against a type of control so that you can clear all the controls on a form back to there defaults.

There is a very simple way to remove NULL values from JSON object. By default JSON object includes NULL values. Following can be used to remove NULL from JSON string

JsonConvert.SerializeObject(yourClassObject, new JsonSerializerSettings() {
                                       NullValueHandling = NullValueHandling.Ignore})) 

Have you tried Aptana? It's based on Eclipse and they have a sweet Rails plugin.

If the "default value" you want is immutable, @eduffy's suggestion, e.g. [0]*10, is good enough.

But if you want, say, a list of ten dicts, do not use [{}]*10 -- that would give you a list with the same initially-empty dict ten times, not ten distinct ones. Rather, use [{} for i in range(10)] or similar constructs, to construct ten separate dicts to make up your list.

$('#thisElement').find('.classToSelect') will find any descendents of #thisElement with class classToSelect.

As others said, you may run your external program without xterm. However, if you want to run it in a terminal window, e.g. to let the user interact with it, xterm allows you to specify the program to run as parameter.

xterm -e any command

In Java code this becomes:

String[] command = { "xterm", "-e", "my", "command", "with", "parameters" };
Runtime.getRuntime().exec(command);

Or, using ProcessBuilder:

String[] command = { "xterm", "-e", "my", "command", "with", "parameters" };
Process proc = new ProcessBuilder(command).start();

-m 1 means return the first match in any given file. But it will still continue to search in other files. Also, if there are two or more matched in the same line, all of them will be displayed.

You can use head -1 to solve this problem:

grep -o -a -m 1 -h -r "Pulsanti Operietur" /path/to/dir | head -1

explanation of each grep option:

-o, --only-matching, print only the matched part of the line (instead of the entire line)
-a, --text, process a binary file as if it were text
-m 1, --max-count, stop reading a file after 1 matching line
-h, --no-filename, suppress the prefixing of file names on output
-r, --recursive, read all files under a directory recursively

My SQL supports the function of a substring_Index where it will return the postion of a value in a string for the n occurance. A similar User defined function could be written to achieve this. Example in the link

Alternatively you could use charindex function call it x times to report the location of each _ given a starting postion +1 of the previously found instance. until a 0 is found

Edit: NM Charindex is the correct function

I couldn't get anything to work until I tried this simple line:

<p style="margin-top:0; margin-bottom:0; line-height:.5"><br /></p>

which allows you to vary a filler line height to your hearts content (I was [probably MISusing Table to get three columns (boxes) of text which I then wanted to line up along the bottom)

I'm an amateur so would appreciate comments

The answer of pratt is bit uncomplete, because when you restart your device your app will working stop, recording stop, its become useless.

i m adding some line that copy in your project for complete working of Pratt answer.

<receiver
        android:name=".DeviceAdminDemo"
        android:permission="android.permission.BIND_DEVICE_ADMIN">

    context.startService(myIntent);

}

Using Ellipsis

Text(
  "This is a long text",
  overflow: TextOverflow.ellipsis,
),

Using Fade

Text(
  "This is a long text",
  overflow: TextOverflow.fade,
  maxLines: 1,
  softWrap: false,
),

Using Clip

Text(
  "This is a long text",
  overflow: TextOverflow.clip,
  maxLines: 1,
  softWrap: false,
),

Note:

If you are using Text inside a Row, you can put above Text inside Expanded like:

Expanded(
  child: AboveText(),
)

For example in my case I accidentaly changed role of some users to incorrect, and my application got error during starting (NullReferenceException). When I fixed it - the app starts fine.

Yes, tasks waiting for IO are blocked, and other tasks get executed. Selecting the next task is done by the Linux scheduler.

you may want to put a break; after your location:

header('Location:  '.  $YourArrayName["YourURL"]  );
break;

You can use the sys.dm_tran_locks view, which returns information about the currently active lock manager resources.

Try this

 SELECT 
     SessionID = s.Session_id,
     resource_type,   
     DatabaseName = DB_NAME(resource_database_id),
     request_mode,
     request_type,
     login_time,
     host_name,
     program_name,
     client_interface_name,
     login_name,
     nt_domain,
     nt_user_name,
     s.status,
     last_request_start_time,
     last_request_end_time,
     s.logical_reads,
     s.reads,
     request_status,
     request_owner_type,
     objectid,
     dbid,
     a.number,
     a.encrypted ,
     a.blocking_session_id,
     a.text       
 FROM   
     sys.dm_tran_locks l
     JOIN sys.dm_exec_sessions s ON l.request_session_id = s.session_id
     LEFT JOIN   
     (
         SELECT  *
         FROM    sys.dm_exec_requests r
         CROSS APPLY sys.dm_exec_sql_text(sql_handle)
     ) a ON s.session_id = a.session_id
 WHERE  
     s.session_id > 50

You can make use of regex's quantifier feature since lookaround may not be supported all the time.

(\bjames\b){1,}.*(\bjack\b){1,}|(\bjack\b){1,}.*(\bjames\b){1,}

You could also do as below. Consider df to be your dataframe and assume a two level index (as is the case in your example)

df.columns = [(df.columns[i][0])+'_'+(datadf_pos4.columns[i][1]) for i in range(len(df.columns))]

I did the following to make this run on AS 3.5

1. app/ build.gradle

   apply plugin: 'com.android.application'

   android { compileSdkVersion 21 buildToolsVersion "25.0.0"

   defaultConfig {
       applicationId "com.example.android.mobileperf.render"

       targetSdkVersion 21
       versionCode 1
       versionName "1.0"
   }
   buildTypes {
       release {
           minifyEnabled false
           proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
       }
   }
   

   }

dependencies { implementation fileTree(dir: 'libs', include: ['*.jar']) implementation 'com.android.support:appcompat-v7:21.0.0' implementation 'com.squareup.picasso:picasso:2.71828' }

2. build.gradle

   buildscript { repositories { jcenter() mavenCentral() maven { url 'https://maven.google.com/' name 'Google' } google() } dependencies { classpath 'com.android.tools.build:gradle:3.0.1' } } allprojects { repositories { jcenter() google() } }

3. gradle-wrapper.properties

   distributionUrl=https://services.gradle.org/distributions/gradle-4.1-all.zip

In recent versions of Gradle (ie. 5+), if you run your build with the --scan flag, it tells you all kinds of useful information, including dependencies, in a browser where you can click around.

gradlew --scan clean build

It will analyze the crap out of what's going on in that build. It's pretty neat.

I was trying to call a REST endpoint from a microservice and I was using the resttemplate's put method.

In my design if any error occurred inside the REST endpoint it should return a JSON error response, it was working for some calls but not for this put one, it returned the white label error page instead.

So I did some investigation and I found out that;

Spring try to understand the caller if it is a machine then it returns JSON response or if it is a browser than it returns the white label error page HTML.

As a result: my client app needed to say to REST endpoint that the caller is a machine, not a browser so for this the client app needed to add 'application/json' into the ACCEPT header explicitly for the resttemplate's 'put' method. I added this to the header and solved the problem.

my call to the endpoint:

restTemplate.put(url, request, param1, param2);

for above call I had to add below header param.

headers.set("Accept", MediaType.APPLICATION_JSON_UTF8_VALUE);

or I tried to change put to exchange as well, in this case, exchange call added the same header for me and solved the problem too but I don't know why :)

restTemplate.exchange(....)

You can use the Enumerable.SequenceEqual() in the System.Linq to compare the contents in the array

bool isEqual = Enumerable.SequenceEqual(target1, target2);

The Node REPL uses the underscore variable to hold the result of the last operation, so it conflicts with the Underscore library's use of the same variable. Try something like this:

Admin-MacBook-Pro:test admin$ node
> _und = require("./underscore-min")
{ [Function]
  _: [Circular],
  VERSION: '1.1.4',
  forEach: [Function],
  each: [Function],
  map: [Function],
  inject: [Function],
  (...more functions...)
  templateSettings: { evaluate: /<%([\s\S]+?)%>/g, interpolate: /<%=([\s\S]+?)%>/g },
  template: [Function] }
> _und.max([1,2,3])
3
> _und.max([4,5,6])
6

Be careful when using these JSON.(parse/stringify) methods. I did the same with complex objects and it turned out that an embedded array with some more objects had the same values for all other entities in the object tree I was serializing.

const temp = [];
const t = {
    name: "name",
    etc: [
        {
            a: 0,
        },
    ],
};
for (let i = 0; i < 3; i++) {
    const bla = Object.assign({}, t);
    bla.name = bla.name + i;
    bla.etc[0].a = i;
    temp.push(bla);
}

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

echo -e ' \t '

will echo 'space tab space newline' (-e means 'enable interpretation of backslash escapes'):

$ echo -e ' \t ' | hexdump -C
00000000  20 09 20 0a                                       | . .|

I was working on a fresh project and got the similar type of problem. I just ran ng update --all and my problem was solved.

You could use async functions to get _id field automatically without manipulating data object:

async function save() {
  const data = {
    name: "John"
  }

  await db.collection('users').insertOne(data)

  return data
}

Returns data:

{
  _id: '5dbff150b407cc129ab571ca',
  name: 'John'
}

More precisely, you have to force the addition of the tag, then push with option --tags and -f:

git tag -f -a <tagname>
git push -f --tags

Here was my solution:

Markup:

<div id="name" disabled="disabled">

Javascript:

document.getElementById("name").disabled = true;

This the best solution for my applications - hope this helps!

Logical operators for boolean indexing in Pandas

It's important to realize that you cannot use any of the Python logical operators (and, or or not) on pandas.Series or pandas.DataFrames (similarly you cannot use them on numpy.arrays with more than one element). The reason why you cannot use those is because they implicitly call bool on their operands which throws an Exception because these data structures decided that the boolean of an array is ambiguous:

>>> import numpy as np
>>> import pandas as pd
>>> arr = np.array([1,2,3])
>>> s = pd.Series([1,2,3])
>>> df = pd.DataFrame([1,2,3])
>>> bool(arr)
ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()
>>> bool(s)
ValueError: The truth value of a Series is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all().
>>> bool(df)
ValueError: The truth value of a DataFrame is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all().

I did cover this more extensively in my answer to the "Truth value of a Series is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all()" Q+A.

NumPys logical functions

However NumPy provides element-wise operating equivalents to these operators as functions that can be used on numpy.array, pandas.Series, pandas.DataFrame, or any other (conforming) numpy.array subclass:

• and has np.logical_and
• or has np.logical_or
• not has np.logical_not
• numpy.logical_xor which has no Python equivalent but is a logical "exclusive or" operation

So, essentially, one should use (assuming df1 and df2 are pandas DataFrames):

np.logical_and(df1, df2)
np.logical_or(df1, df2)
np.logical_not(df1)
np.logical_xor(df1, df2)

Bitwise functions and bitwise operators for booleans

However in case you have boolean NumPy array, pandas Series, or pandas DataFrames you could also use the element-wise bitwise functions (for booleans they are - or at least should be - indistinguishable from the logical functions):

• bitwise and: np.bitwise_and or the & operator
• bitwise or: np.bitwise_or or the | operator
• bitwise not: np.invert (or the alias np.bitwise_not) or the ~ operator
• bitwise xor: np.bitwise_xor or the ^ operator

Typically the operators are used. However when combined with comparison operators one has to remember to wrap the comparison in parenthesis because the bitwise operators have a higher precedence than the comparison operators:

(df1 < 10) | (df2 > 10)  # instead of the wrong df1 < 10 | df2 > 10

This may be irritating because the Python logical operators have a lower precendence than the comparison operators so you normally write a < 10 and b > 10 (where a and b are for example simple integers) and don't need the parenthesis.

Differences between logical and bitwise operations (on non-booleans)

It is really important to stress that bit and logical operations are only equivalent for boolean NumPy arrays (and boolean Series & DataFrames). If these don't contain booleans then the operations will give different results. I'll include examples using NumPy arrays but the results will be similar for the pandas data structures:

>>> import numpy as np
>>> a1 = np.array([0, 0, 1, 1])
>>> a2 = np.array([0, 1, 0, 1])

>>> np.logical_and(a1, a2)
array([False, False, False,  True])
>>> np.bitwise_and(a1, a2)
array([0, 0, 0, 1], dtype=int32)

And since NumPy (and similarly pandas) does different things for boolean (Boolean or “mask” index arrays) and integer (Index arrays) indices the results of indexing will be also be different:

>>> a3 = np.array([1, 2, 3, 4])

>>> a3[np.logical_and(a1, a2)]
array([4])
>>> a3[np.bitwise_and(a1, a2)]
array([1, 1, 1, 2])

Summary table

Logical operator | NumPy logical function | NumPy bitwise function | Bitwise operator
-------------------------------------------------------------------------------------
       and       |  np.logical_and        | np.bitwise_and         |        &
-------------------------------------------------------------------------------------
       or        |  np.logical_or         | np.bitwise_or          |        |
-------------------------------------------------------------------------------------
                 |  np.logical_xor        | np.bitwise_xor         |        ^
-------------------------------------------------------------------------------------
       not       |  np.logical_not        | np.invert              |        ~

Where the logical operator does not work for NumPy arrays, pandas Series, and pandas DataFrames. The others work on these data structures (and plain Python objects) and work element-wise. However be careful with the bitwise invert on plain Python bools because the bool will be interpreted as integers in this context (for example ~False returns -1 and ~True returns -2).

Those are unicode escapes. The general unicode escapes looks like \uxxxx where xxxx are the hexadecimal digits of the ASCI characters. They are used mainly to insert special characters inside a javascript string.

In ORACLE: UNION does not support BLOB (or CLOB) column types, UNION ALL does.

After few successes and failures, I came up with this solution:

const isInt = (value) => {
  return String(parseInt(value, 10)) === String(value)
}

I liked the idea above of checking the value for not being NaN and use parseFloat, but when I tried it in React infrastructure it didn't work for some reason.

Edit: I found a nicer way without using strings:

var isInt = function (str) {
  return str === '0' || !!~~str;
}

I think it's the shortest answer. Maybe even the most efficient, but I could be stand corrected. :)

Based on what you provided, it is pretty simple for what you need to do and you even have a number of ways to go about doing it. You'll need something that'll let you post a body with your request. Almost any programming language can do this as well as command line tools like cURL.

One you have your tool decided, you'll need to create your JSON body and submit it to the server.

An example using cURL would be (all in one line, minus the \ at the end of the first line):

curl -v -H "Content-Type: application/json" -X POST \
     -d '{"name":"your name","phonenumber":"111-111"}' http://www.abc.com/details

The above command will create a request that should look like the following:

POST /details HTTP/1.1
Host: www.abc.com
Content-Type: application/json
Content-Length: 44

{"name":"your name","phonenumber":"111-111"}

Delete the .metadata folder in your workspace.

def oneFunction(lists):
    category=random.choice(list(lists.keys()))
    word=random.choice(lists[category])
    return word

def anotherFunction():
    for letter in word:             
        print("_",end=" ")

Do doubles always have 16 significant figures while floats always have 7 significant figures?

No. Doubles always have 53 significant bits and floats always have 24 significant bits (except for denormals, infinities, and NaN values, but those are subjects for a different question). These are binary formats, and you can only speak clearly about the precision of their representations in terms of binary digits (bits).

This is analogous to the question of how many digits can be stored in a binary integer: an unsigned 32 bit integer can store integers with up to 32 bits, which doesn't precisely map to any number of decimal digits: all integers of up to 9 decimal digits can be stored, but a lot of 10-digit numbers can be stored as well.

Why don't doubles have 14 significant figures?

The encoding of a double uses 64 bits (1 bit for the sign, 11 bits for the exponent, 52 explicit significant bits and one implicit bit), which is double the number of bits used to represent a float (32 bits).

With this we can change the color of textfield's placeholder text in iOS

[self.userNameTxt setValue:[UIColor colorWithRed:41.0/255.0 green:91.0/255.0 blue:106.0/255.0 alpha:1.0] forKeyPath:@"_placeholderLabel.textColor"];

You can use URL.createObjectURL

    function img_pathUrl(input){
        $('#img_url')[0].src = (window.URL ? URL : webkitURL).createObjectURL(input.files[0]);
    }

#img_url {
  background: #ddd;
  width:100px;
  height: 90px;
  display: block;
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<img src="" id="img_url" alt="your image">
<br>
<input type="file" id="img_file" onChange="img_pathUrl(this);">

Depending on your shell implementation (e.g. Busybox vs. grown-up) the [ operator might start a process, changing $?.

Try

getent passwd $1 > /dev/null 2&>1
RES=$?

if [ $RES -eq 0 ]; then
    echo "yes the user exists"
else
    echo "No, the user does not exist"
fi

You can use one-line heredoc

cat <<< "This is coming from the stdin"

the above is the same as

cat <<EOF
This is coming from the stdin
EOF

or you can redirect output from a command, like

diff <(ls /bin) <(ls /usr/bin)

or you can read as

while read line
do
   echo =$line=
done < some_file

or simply

echo something | read param

In Python 3.x the process might hang because the output is a byte array instead of a string. Make sure you decode it into a string.

Starting from Python 3.6 you can do it using the parameter encoding in Popen Constructor. The complete example:

process = subprocess.Popen(
    'my_command',
    stdout=subprocess.PIPE,
    stderr=subprocess.STDOUT,
    shell=True,
    encoding='utf-8',
    errors='replace'
)

while True:
    realtime_output = process.stdout.readline()

    if realtime_output == '' and process.poll() is not None:
        break

    if realtime_output:
        print(realtime_output.strip(), flush=True)

Note that this code redirects stderr to stdout and handles output errors.

There is an option to generate php5 objects with WsdlInterpreter class. See more here: https://github.com/gkwelding/WSDLInterpreter

for example:

require_once 'WSDLInterpreter-v1.0.0/WSDLInterpreter.php';
$wsdlLocation = '<your wsdl url>?wsdl';
$wsdlInterpreter = new WSDLInterpreter($wsdlLocation);
$wsdlInterpreter->savePHP('.');

I had the same problem. Adding new rows to WPF DataGrid requires a trick. DataGrid relies on property fields of an item object. ExpandoObject enables to add new properties dynamically. The code below explains how to do it:

// using System.Dynamic;

DataGrid dataGrid;

string[] labels = new string[] { "Column 0", "Column 1", "Column 2" };

foreach (string label in labels)
{
    DataGridTextColumn column = new DataGridTextColumn();
    column.Header = label;
    column.Binding = new Binding(label.Replace(' ', '_'));

    dataGrid.Columns.Add(column);
}

int[] values = new int[] { 0, 1, 2 };

dynamic row = new ExpandoObject();

for (int i = 0; i < labels.Length; i++)
    ((IDictionary<String, Object>)row)[labels[i].Replace(' ', '_')] = values[i];

dataGrid.Items.Add(row);

//edit:

Note that this is not the way how the component should be used, however, it simplifies a lot if you have only programmatically generated data (eg. in my case: a sequence of features and neural network output).

A lot of the answers on here use regexes, this is fine but it doesn't handle new additions to the language too well (like arrow functions and classes). Also of note is that if you use any of these functions on minified code it's going to go . It will use whatever the minified name is. Angular gets around this by allowing you to pass in an ordered array of strings that matches the order of the arguments when registering them with the DI container. So on with the solution:

var esprima = require('esprima');
var _ = require('lodash');

const parseFunctionArguments = (func) => {
    // allows us to access properties that may or may not exist without throwing 
    // TypeError: Cannot set property 'x' of undefined
    const maybe = (x) => (x || {});

    // handle conversion to string and then to JSON AST
    const functionAsString = func.toString();
    const tree = esprima.parse(functionAsString);
    console.log(JSON.stringify(tree, null, 4))
    // We need to figure out where the main params are. Stupid arrow functions 
    const isArrowExpression = (maybe(_.first(tree.body)).type == 'ExpressionStatement');
    const params = isArrowExpression ? maybe(maybe(_.first(tree.body)).expression).params 
                                     : maybe(_.first(tree.body)).params;

    // extract out the param names from the JSON AST
    return _.map(params, 'name');
};

This handles the original parse issue and a few more function types (e.g. arrow functions). Here's an idea of what it can and can't handle as is:

// I usually use mocha as the test runner and chai as the assertion library
describe('Extracts argument names from function signature. ', () => {
    const test = (func) => {
        const expectation = ['it', 'parses', 'me'];
        const result = parseFunctionArguments(toBeParsed);
        result.should.equal(expectation);
    } 

    it('Parses a function declaration.', () => {
        function toBeParsed(it, parses, me){};
        test(toBeParsed);
    });

    it('Parses a functional expression.', () => {
        const toBeParsed = function(it, parses, me){};
        test(toBeParsed);
    });

    it('Parses an arrow function', () => {
        const toBeParsed = (it, parses, me) => {};
        test(toBeParsed);
    });

    // ================= cases not currently handled ========================

    // It blows up on this type of messing. TBH if you do this it deserves to 
    // fail  On a tech note the params are pulled down in the function similar 
    // to how destructuring is handled by the ast.
    it('Parses complex default params', () => {
        function toBeParsed(it=4*(5/3), parses, me) {}
        test(toBeParsed);
    });

    // This passes back ['_ref'] as the params of the function. The _ref is a 
    // pointer to an VariableDeclarator where the ? happens.
    it('Parses object destructuring param definitions.' () => {
        function toBeParsed ({it, parses, me}){}
        test(toBeParsed);
    });

    it('Parses object destructuring param definitions.' () => {
        function toBeParsed ([it, parses, me]){}
        test(toBeParsed);
    });

    // Classes while similar from an end result point of view to function
    // declarations are handled completely differently in the JS AST. 
    it('Parses a class constructor when passed through', () => {
        class ToBeParsed {
            constructor(it, parses, me) {}
        }
        test(ToBeParsed);
    });
});

Depending on what you want to use it for ES6 Proxies and destructuring may be your best bet. For example if you wanted to use it for dependency injection (using the names of the params) then you can do it as follows:

class GuiceJs {
    constructor() {
        this.modules = {}
    }
    resolve(name) {
        return this.getInjector()(this.modules[name]);
    }
    addModule(name, module) {
        this.modules[name] = module;
    }
    getInjector() {
        var container = this;

        return (klass) => {
            console.log(klass);
            var paramParser = new Proxy({}, {
                // The `get` handler is invoked whenever a get-call for
                // `injector.*` is made. We make a call to an external service
                // to actually hand back in the configured service. The proxy
                // allows us to bypass parsing the function params using
                // taditional regex or even the newer parser.
                get: (target, name) => container.resolve(name),

                // You shouldn't be able to set values on the injector.
                set: (target, name, value) => {
                    throw new Error(`Don't try to set ${name}! `);
                }
            })
            return new klass(paramParser);
        }
    }
}

It's not the most advanced resolver out there but it gives an idea of how you can use a Proxy to handle it if you want to use args parser for simple DI. There is however one slight caveat in this approach. We need to use destructuring assignments instead of normal params. When we pass in the injector proxy the destructuring is the same as calling the getter on the object.

class App {
   constructor({tweeter, timeline}) {
        this.tweeter = tweeter;
        this.timeline = timeline;
    }
}

class HttpClient {}

class TwitterApi {
    constructor({client}) {
        this.client = client;
    }
}

class Timeline {
    constructor({api}) {
        this.api = api;
    }
}

class Tweeter {
    constructor({api}) {
        this.api = api;
    }
}

// Ok so now for the business end of the injector!
const di = new GuiceJs();

di.addModule('client', HttpClient);
di.addModule('api', TwitterApi);
di.addModule('tweeter', Tweeter);
di.addModule('timeline', Timeline);
di.addModule('app', App);

var app = di.resolve('app');
console.log(JSON.stringify(app, null, 4));

This outputs the following:

{
    "tweeter": {
        "api": {
            "client": {}
        }
    },
    "timeline": {
        "api": {
            "client": {}
        }
    }
}

Its wired up the entire application. The best bit is that the app is easy to test (you can just instantiate each class and pass in mocks/stubs/etc). Also if you need to swap out implementations, you can do that from a single place. All this is possible because of JS Proxy objects.

Note: There is a lot of work that would need to be done to this before it would be ready for production use but it does give an idea of what it would look like.

It's a bit late in the answer but it may help others who are thinking of the same thing.

git shelve doesn't exist in Git.

Only git stash:

• when you want to record the current state of the working directory and the index, but want to go back to a clean working directory.
• which saves your local modifications away and reverts the working directory to match the HEAD commit.

You had a 2008 old project git shelve to isolate modifications in a branch, but that wouldn't be very useful nowadays.

As documented in Intellij IDEA shelve dialog, the feature "shelving and unshelving" is not linked to a VCS (Version Control System tool) but to the IDE itself, to temporarily storing pending changes you have not committed yet in changelist.

Note that since Git 2.13 (Q2 2017), you now can stash individual files too.

This could cause for any new terminal, the agent id is different. You need to add the Private key for the agent

$ ssh-add <path to your private key>

If the width of the table won't change, you can set the width of the element (such as tbody) that contains the scrollbar > 100% (allowing extra space for the scrollbar) and set overflow-y to "overlay" (so that the scrollbar stays fixed, and won't shift the table left when it appears). Also set a fixed height for the element with the scrollbar, so the scrollbar will appear once the height is exceeded. Like so:

tbody {
  height: 100px;
  overflow-y: overlay;
  width: 105%
}

Note: you will have to manually adjust the width % as the % of space the scrollbar takes up will be relative to your table width (ie: smaller width of table, more % required to fit the scrollbar, as it's size in pixels is constant)

They don't exist in MySQL do they? Just use a temp table:

CREATE PROCEDURE my_proc () BEGIN 

CREATE TEMPORARY TABLE TempTable (myid int, myfield varchar(100)); 
INSERT INTO TempTable SELECT tblid, tblfield FROM Table1; 

/* Do some more stuff .... */

From MySQL here

"You can use the TEMPORARY keyword when creating a table. A TEMPORARY table is visible only to the current connection, and is dropped automatically when the connection is closed. This means that two different connections can use the same temporary table name without conflicting with each other or with an existing non-TEMPORARY table of the same name. (The existing table is hidden until the temporary table is dropped.)"

if you use 'Month' in to_char it right pads to 9 characters; you have to use the abbreviated 'MON', or to_char then trim and concatenate it to avoid this. See, http://www.techonthenet.com/oracle/functions/to_char.php

select trim(to_char(date_field, 'month')) || ' ' || to_char(date_field,'dd, yyyy')
  from ...

or

select to_char(date_field,'mon dd, yyyy')
  from ...  

On input type=file add an event onchange="preview()"

For the function preview() type:

thumb.src=URL.createObjectURL(event.target.files[0]);

Live example:

function preview() {
   thumb.src=URL.createObjectURL(event.target.files[0]);
}

<form>
    <input type="file" onchange="preview()">
    <img id="thumb" src="" width="150px"/>
</form>

I wanted a solution to copy files modified after a certain date and time which mean't I need to use Get-ChildItem piped through a filter. Below is what I came up with:

$SourceFolder = "C:\Users\RCoode\Documents\Visual Studio 2010\Projects\MyProject"
$ArchiveFolder = "J:\Temp\Robin\Deploy\MyProject"
$ChangesStarted = New-Object System.DateTime(2013,10,16,11,0,0)
$IncludeFiles = ("*.vb","*.cs","*.aspx","*.js","*.css")

Get-ChildItem $SourceFolder -Recurse -Include $IncludeFiles | Where-Object {$_.LastWriteTime -gt $ChangesStarted} | ForEach-Object {
    $PathArray = $_.FullName.Replace($SourceFolder,"").ToString().Split('\') 

    $Folder = $ArchiveFolder

    for ($i=1; $i -lt $PathArray.length-1; $i++) {
        $Folder += "\" + $PathArray[$i]
        if (!(Test-Path $Folder)) {
            New-Item -ItemType directory -Path $Folder
        }
    }   
    $NewPath = Join-Path $ArchiveFolder $_.FullName.Replace($SourceFolder,"")

    Copy-Item $_.FullName -Destination $NewPath  
}

in is the intended way to test for the existence of a key in a dict.

d = {"key1": 10, "key2": 23}

if "key1" in d:
    print("this will execute")

if "nonexistent key" in d:
    print("this will not")

If you wanted a default, you can always use dict.get():

d = dict()

for i in range(100):
    key = i % 10
    d[key] = d.get(key, 0) + 1

and if you wanted to always ensure a default value for any key you can either use dict.setdefault() repeatedly or defaultdict from the collections module, like so:

from collections import defaultdict

d = defaultdict(int)

for i in range(100):
    d[i % 10] += 1

but in general, the in keyword is the best way to do it.

Where do these values come from? The documentation for android:fontFamily does not list this information in any place

These are indeed not listed in the documentation. But they are mentioned here under the section 'Font families'. The document lists every new public API for Android Jelly Bean 4.1.

In the styles.xml file in the application I'm working on somebody listed this as the font family, and I'm pretty sure it's wrong:

Yes, that's wrong. You don't reference the font file, you have to use the font name mentioned in the linked document above. In this case it should have been this:

<item name="android:fontFamily">sans-serif</item>

Like the linked answer already stated, 12 variants are possible:

Added in Android Jelly Bean (4.1) - API 16 :

Regular (default):

<item name="android:fontFamily">sans-serif</item>

For quick reference, this is how they all look like:

A friend was having issues in Internet Explorer 8 and showed me what he did. I told him it was wrong, and he told me he got the answer here. The current top answer will not work in all browsers (Internet Explorer 8 for example), and it will only remove the first occurrence of the item.

Remove ALL instances from an array

function array_remove_index_by_value(arr, item)
{
 for (var i = arr.length; i--;)
 {
  if (arr[i] === item) {arr.splice(i, 1);}
 }
}

It loops through the array backwards (since indices and length will change as items are removed) and removes the item if it's found. It works in all browsers.

Last-Modified : The last modified date for the requested object

If-Modified-Since : Allows a 304 Not Modified to be returned if last modified date is unchanged.

ETag : An ETag is an opaque identifier assigned by a web server to a specific version of a resource found at a URL. If the resource representation at that URL ever changes, a new and different ETag is assigned.

If-None-Match : Allows a 304 Not Modified to be returned if ETag is unchanged.

the browser store cache with a date(Last-Modified) or id(ETag), when you need to request the URL again, the browser send request message with the header:

the server will return 304 when the if statement is False, and browser will use cache.

please try this below command :

sudo php artisan cache:clear

sudo php artisan view:clear

sudo php artisan config:cache

Resorting to a PivotTable might not count as using formulas only but seems more practical that most other suggestions so far:

maytham-???i???, you can use this code to simulate input of file:

System.setIn(new FileInputStream("FILE_NAME"));

Or send file name as parameter and then put it into FileInputStream:

System.setIn(new FileInputStream(args[0]));

Go to "Window -> Preferences -> General -> C/C++ -> Code analysis" and disable "Syntax and Semantics Errors -> Abstract class cannot be instantiated"

I would just like to add that in my case rubygems wasn't installed.

Running sudo apt-get install rubygems solved the issue!

Yo could also set labels = FALSE inside axis(...) and print the labels in a separate command with Text. With this option you can rotate the text the text in case you need it

lablist<-as.vector(c(1:10))
axis(1, at=seq(1, 10, by=1), labels = FALSE)
text(seq(1, 10, by=1), par("usr")[3] - 0.2, labels = lablist, srt = 45, pos = 1, xpd = TRUE)

Detailed explanation here

The way we have done it was using Broadcasts:

1. Send the broadcast every time the user changes language
2. Register the broadcast receiver in the AppActivity.onCreate() and unregister in AppActivity.onDestroy()
3. In BroadcastReceiver.onReceive() just restart the activity.

AppActivity is the parent activity which all other activities subclass.

Below is the snippet from my code, not tested outside the project, but should give you a nice idea.

When the user changes the language

sendBroadcast(new Intent("Language.changed"));

And in the parent activity

public class AppActivity extends Activity {

    /**
     * The receiver that will handle the change of the language.
     */
    private BroadcastReceiver mLangaugeChangedReceiver;

    @Override
    protected void onCreate(final Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // ...
        // Other code here
        // ...

        // Define receiver
        mLangaugeChangedReceiver = new BroadcastReceiver() {

            @Override
            public void onReceive(final Context context, final Intent intent) {
                startActivity(getIntent());
                finish();
            }
        };

        // Register receiver
        registerReceiver(mLangaugeChangedReceiver, new IntentFilter("Language.changed"));
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();

        // ...
        // Other cleanup code here
        // ...

        // Unregister receiver
        if (mLangaugeChangedReceiver != null) {
            try {
                unregisterReceiver(mLangaugeChangedReceiver);
                mLangaugeChangedReceiver = null;
            } catch (final Exception e) {}
        }
    }
}

This will also refresh the activity which changed the language (if it subclasses the above activity).

This will make you lose any data, but if it is important you should already have taken care of this using Actvity.onSaveInstanceState() and Actvity.onRestoreInstanceState() (or similar).

Let me know your thoughts about this.

Cheers!

How to remove all .git directories under a folder in Linux.

Run this find command, it will list all .git directories under the current folder:

find . -type d -name ".git" \
&& find . -name ".gitignore" \
&& find . -name ".gitmodules"

Prints:

./.git
./.gitmodules
./foobar/.git
./footbar2/.git
./footbar2/.gitignore

There should only be like 3 or 4 .git directories because git only has one .git folder for every project. You can rm -rf yourpath each of the above by hand.

If you feel like removing them all in one command and living dangerously:

//Retrieve all the files named ".git" and pump them into 'rm -rf'
//WARNING if you don't understand why/how this command works, DO NOT run it!

( find . -type d -name ".git" \
  && find . -name ".gitignore" \
  && find . -name ".gitmodules" ) | xargs rm -rf

//WARNING, if you accidentally pipe a `.` or `/` or other wildcard
//into xargs rm -rf, then the next question you will have is: "why is
//the bash ls command not found?  Requiring an OS reinstall.

Sorry for comment in an old post but if you want to use an else if statement this will help you

An intuitive script: dplyr::select_if(~!all(is.na(.))). It literally keeps only not-all-elements-missing columns. (to delete all-element-missing columns).

> df <- data.frame( id = 1:10 , nas = rep( NA , 10 ) , vals = sample( c( 1:3 , NA ) , 10 , repl = TRUE ) )

> df %>% glimpse()
Observations: 10
Variables: 3
$ id   <int> 1, 2, 3, 4, 5, 6, 7, 8, 9, 10
$ nas  <lgl> NA, NA, NA, NA, NA, NA, NA, NA, NA, NA
$ vals <int> NA, 1, 1, NA, 1, 1, 1, 2, 3, NA

> df %>% select_if(~!all(is.na(.))) 
   id vals
1   1   NA

Use a ValueConverter

[ValueConversion(typeof(string), typeof(String))]
public class MyConverter: IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        return string.Format("{0}:{1}", (string) value, (string) parameter);
    }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {

        return DependencyProperty.UnsetValue;
    }
}

and in the markup

<src:MyConverter x:Key="MyConverter"/>

. . .

<TextBlock Text="{Binding Name, Converter={StaticResource MyConverter Parameter=ID}}" />

You can use Ctrl+Shift+Down+D to add the formula to every cell in the column as well.

Simply click/highlight the cell with the equation/formula you want to copy and then hold down Ctrl+Shift+Down+D and your formula will be added to each cell.

You can also use the Number constructor/function (no need for a radix and usable for both integers and floats):

Number('09'); /=> 9
Number('09.0987'); /=> 9.0987

Alternatively like Andy E said in the comments you can use + for conversion

+'09'; /=> 9
+'09.0987'; /=> 9.0987

It seems that Luiggi Mendoza and joey rohan both already answered this, but I think it can be clarified a little.

You can write it as a single if statement:

if (inventory.contains("bread") && !inventory.contains("water")) {
    // do something
}

You also have an error in your css with the exclamation point in this line:

background:rgb(242, 242, 242);!important;

remove the semi-colon before it. However, !important should be used rarely and can largely be avoided.

The O(NLog(N)) Recursive DP Approach To Finding the Longest Increasing Subsequence (LIS)

Explanation

This algorithm involves creating a tree with node format as (a,b).

a represents the next element we are considering appending to the valid subsequence so far.

b represents the starting index of the remaining subarray that the next decision will be made from if a gets appended to the end of the subarray we have so far.

Algorithm

1. We start with an invalid root (INT_MIN,0), pointing at index zero of the array since subsequence is empty at this point, i.e. b = 0.

2. Base Case: return 1 if b >= array.length.

3. Loop through all the elements in the array from the b index to the end of the array, i.e i = b ... array.length-1. i) If an element, array[i] is greater than the current a, it is qualified to be considered as one of the elements to be appended to the subsequence we have so far. ii) Recurse into the node (array[i],b+1), where a is the element we encountered in 2(i) which is qualified to be appended to the subsequence we have so far. And b+1 is the next index of the array to be considered. iii) Return the max length obtained by looping through i = b ... array.length. In a case where a is bigger than any other element from i = b to array.length, return 1.

4. Compute the level of the tree built as level. Finally, level - 1 is the desired LIS. That is the number of edges in the longest path of the tree.

NB: The memorization part of the algorithm is left out since it's clear from the tree.

Random Example Nodes marked x are fetched from the DB memoized values.

Java Implementation

public int lengthOfLIS(int[] nums) {
            return LIS(nums,Integer.MIN_VALUE, 0,new HashMap<>()) -1;
    }
    public int LIS(int[] arr, int value, int nextIndex, Map<String,Integer> memo){
        if(memo.containsKey(value+","+nextIndex))return memo.get(value+","+nextIndex);
        if(nextIndex >= arr.length)return 1;

        int max = Integer.MIN_VALUE;
        for(int i=nextIndex; i<arr.length; i++){
            if(arr[i] > value){
                max = Math.max(max,LIS(arr,arr[i],i+1,memo));
            }
        }
        if(max == Integer.MIN_VALUE)return 1;
        max++;
        memo.put(value+","+nextIndex,max);
        return max;
    }

You can do this using the query builder. Just use SELECT instead of TABLE and GET.

DB::select('select * from user where name = ?',['Jhon']);

Notes: 1. Multiple question marks are allowed. 2. The second parameter must be an array, even if there is only one parameter. 3. Laravel will automatically clean parameters, so you don't have to.

Hmmmmmm, turns out that still returns a standard class for me when I don't use a where clause. I found this helped:

foreach($results as $result)
{
print_r(get_object_vars($result));
}

However, get_object_vars isn't recursive, so don't use it on $results.

use this code

echo '<script language="javascript">';
echo 'alert("message successfully sent")';
echo '</script>';

The problem was:

1. you missed "
2. It should be alert not alery

The same happened for me with eslint module. EsLinter throw Parsing error: Invalid left-hand side in assignment expression for await in second if statement.

if (condition_one) {
  let result = await myFunction()
}

if (condition_two) {
  let result = await myFunction() // eslint parsing error
}

As strange as it sounds what fixed this error was to add ; semicolon at the end of line where await occurred.

if (condition_one) {
  let result = await myFunction();
}

if (condition_two) {
  let result = await myFunction();
}

global $wpdb;


$your_table  = $wpdb->prefix. 'My_Table_Name';
$your_column =                'My_Column_Name'; 

if (!in_array($your_column, $wpdb->get_col( "DESC " . $your_table, 0 ) )){  $result= $wpdb->query(
    "ALTER     TABLE $your_table     ADD $your_column     VARCHAR(100)     CHARACTER SET utf8     NOT NULL     "  //you can add positioning phraze: "AFTER My_another_column"
);}

You can do one of the following:

<?php
    $data = 'My data';

    function menugen() {
        global $data;
        echo "[" . $data . "]";
    }

    menugen();

Or

<?php
    $data = 'My data';

    function menugen() {
        echo "[" . $GLOBALS['data'] . "]";
    }

    menugen();

That being said, overuse of globals can lead to some poor code. It is usually better to pass in what you need. For example, instead of referencing a global database object you should pass in a handle to the database and act upon that. This is called dependency injection. It makes your life a lot easier when you implement automated testing (which you should).

you will not use a layout file. Instead, specify your splash screen’s background as the activity’s theme background. To do this, first create an XML drawable in res/drawable.

Note: all code below is available GitHub Link

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

    <item
        android:drawable="@color/gray"/>

    <item>
        <bitmap
            android:gravity="center"
            android:src="@mipmap/ic_launcher"/>
    </item>

</layer-list>

Here, I’ve set up a background color and an image.

Next, you will set this as your splash activity’s background in the theme. Navigate to your styles.xml file and add a new theme for your splash activity:

<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
    </style>

    <style name="SplashTheme" parent="Theme.AppCompat.NoActionBar">
        <item name="android:windowBackground">@drawable/background_splash</item>
    </style>

</resources>

In your new SplashTheme, set the window background attribute to your XML drawable. Configure this as your splash activity’s theme in your AndroidManifest.xml:

<activity
    android:name=".SplashActivity"
    android:theme="@style/SplashTheme">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />

        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>

Finally, your SplashActivity class should just forward you along to your main activity:

public class SplashActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        Intent intent = new Intent(this, MainActivity.class);
        startActivity(intent);
        finish();
    }
}

Notice that you don’t even set up a view for this SplashActivity. The view comes from the theme. When you set up the UI for your splash activity in the theme, it is available immediately.

If you did have a layout file for your splash activity, that layout file would be visible to the user only after your app has been fully initialized, which is too late. You want the splash to be displayed only in that small amount of time before the app is initialized.

Why would you want to convert key strokes to text? Add a button that sends the text inside the textarea to the server when clicked. You can get the text using the value attribute as the poster before has pointed out, or using jQuery's API:

$('input#mybutton').click(function() {
    var text = $('textarea#mytextarea').val();
    //send to server and process response
});

Evaluate might suit:

Function Eval(Ref As String)
    Application.Volatile
    Eval = Evaluate(Ref)
End Function

If you set the Content-Length HTTP header in your "Thank You For Registering" response, then the browser should close the connection after the specified number of bytes are received. This leaves the server side process running (assuming that ignore_user_abort is set) so it can finish working without making the end user wait.

Of course you will need to calculate the size of your response content before rendering the headers, but that's pretty easy for short responses (write output to a string, call strlen(), call header(), render string).

This approach has the advantage of not forcing you to manage a "front end" queue, and although you may need to do some work on the back end to prevent racing HTTP child processes from stepping on each other, that's something you needed to do already, anyway.

POCOs(Plain old CLR objects) are simply entities of your Domain. Normally when we use entity framework the entities are generated automatically for you. This is great but unfortunately these entities are interspersed with database access functionality which is clearly against the SOC (Separation of concern). POCOs are simple entities without any data access functionality but still gives the capabilities all EntityObject functionalities like

• Lazy loading
• Change tracking

Here is a good start for this

POCO Entity framework

You can also generate POCOs so easily from your existing Entity framework project using Code generators.

EF 5.X DbContext code generator

Though weirdly named, you can use the getimagesize() function. This will also give you mime information:

Array
(
    [0] => 295 // width
    [1] => 295 // height
    [2] => 3 // http://php.net/manual/en/image.constants.php
    [3] => width="295" height="295" // width and height as attr's
    [bits] => 8
    [mime] => image/png
)

For cases of appending to end of existing string:

string = "Sec_"
string += "C_type"
print(string)

results in

Sec_C_type

First, in Python, if your code is CPU-bound, multithreading won't help, because only one thread can hold the Global Interpreter Lock, and therefore run Python code, at a time. So, you need to use processes, not threads.

This is not true if your operation "takes forever to return" because it's IO-bound—that is, waiting on the network or disk copies or the like. I'll come back to that later.

Next, the way to process 5 or 10 or 100 items at once is to create a pool of 5 or 10 or 100 workers, and put the items into a queue that the workers service. Fortunately, the stdlib multiprocessing and concurrent.futures libraries both wraps up most of the details for you.

The former is more powerful and flexible for traditional programming; the latter is simpler if you need to compose future-waiting; for trivial cases, it really doesn't matter which you choose. (In this case, the most obvious implementation with each takes 3 lines with futures, 4 lines with multiprocessing.)

If you're using 2.6-2.7 or 3.0-3.1, futures isn't built in, but you can install it from PyPI (pip install futures).

Finally, it's usually a lot simpler to parallelize things if you can turn the entire loop iteration into a function call (something you could, e.g., pass to map), so let's do that first:

def try_my_operation(item):
    try:
        api.my_operation(item)
    except:
        print('error with item')

Putting it all together:

executor = concurrent.futures.ProcessPoolExecutor(10)
futures = [executor.submit(try_my_operation, item) for item in items]
concurrent.futures.wait(futures)

If you have lots of relatively small jobs, the overhead of multiprocessing might swamp the gains. The way to solve that is to batch up the work into larger jobs. For example (using grouper from the itertools recipes, which you can copy and paste into your code, or get from the more-itertools project on PyPI):

def try_multiple_operations(items):
    for item in items:
        try:
            api.my_operation(item)
        except:
            print('error with item')

executor = concurrent.futures.ProcessPoolExecutor(10)
futures = [executor.submit(try_multiple_operations, group) 
           for group in grouper(5, items)]
concurrent.futures.wait(futures)

Finally, what if your code is IO bound? Then threads are just as good as processes, and with less overhead (and fewer limitations, but those limitations usually won't affect you in cases like this). Sometimes that "less overhead" is enough to mean you don't need batching with threads, but you do with processes, which is a nice win.

So, how do you use threads instead of processes? Just change ProcessPoolExecutor to ThreadPoolExecutor.

If you're not sure whether your code is CPU-bound or IO-bound, just try it both ways.

Can I do this for multiple functions in my python script? For example, if I had another for loop elsewhere in the code that I wanted to parallelize. Is it possible to do two multi threaded functions in the same script?

Yes. In fact, there are two different ways to do it.

First, you can share the same (thread or process) executor and use it from multiple places with no problem. The whole point of tasks and futures is that they're self-contained; you don't care where they run, just that you queue them up and eventually get the answer back.

Alternatively, you can have two executors in the same program with no problem. This has a performance cost—if you're using both executors at the same time, you'll end up trying to run (for example) 16 busy threads on 8 cores, which means there's going to be some context switching. But sometimes it's worth doing because, say, the two executors are rarely busy at the same time, and it makes your code a lot simpler. Or maybe one executor is running very large tasks that can take a while to complete, and the other is running very small tasks that need to complete as quickly as possible, because responsiveness is more important than throughput for part of your program.

If you don't know which is appropriate for your program, usually it's the first.

You can just make a list:

import random
list1=['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h']
b=random.randint(0,7)
print(list1[b])

If you don't want to jQuery, here's the vanilla JavaScript:

///Mute
var video = document.getElementById("your-video-id");
video.muted= true;

//Unmute
var video = document.getElementById("your-video-id");
video.muted= false;

It will work for audio too, just put the element's id and it will work (and change the var name if you want, to 'media' or something suited for both audio/video as you like).

You should take a look at Batarang for AngularJS debugging

As for your issue:

Your scope variable is not directly attached to the modal correctly. Below is the adjusted code. You need to specify when the modal shows using ng-show

There are in fact multiples things you need to know about indentation in Python:

Python really cares about indention.

In a lot of other languages the indention is not necessary but improves readability. In Python indentation replaces the keyword begin / end or { } and is therefore necessary.

This is verified before the execution of the code, therefore even if the code with the indentation error is never reached, it won't work.

There are different indention errors and you reading them helps a lot:

1. "IndentationError: expected an indented block"

They are two main reasons why you could have such an error:

- You have a ":" without an indented block behind.

Here are two examples:

Example 1, no indented block:

Input:

if 3 != 4:
    print("usual")
else:

Output:

  File "<stdin>", line 4

    ^
IndentationError: expected an indented block

The output states that you need to have an indented block on line 4, after the else: statement

Example 2, unindented block:

Input:

if 3 != 4:
print("usual")

Output

  File "<stdin>", line 2
    print("usual")
        ^
IndentationError: expected an indented block

The output states that you need to have an indented block line 2, after the if 3 != 4: statement

- You are using Python2.x and have a mix of tabs and spaces:

Input

def foo():
    if 1:
        print 1

Please note that before if, there is a tab, and before print there is 8 spaces.

Output:

  File "<stdin>", line 3
    print 1
      ^
IndentationError: expected an indented block

It's quite hard to understand what is happening here, it seems that there is an indent block... But as I said, I've used tabs and spaces, and you should never do that.

• You can get some info here.
• Remove all tabs and replaces them by four spaces.
• And configure your editor to do that automatically.

2. "IndentationError: unexpected indent"

It is important to indent blocks, but only blocks that should be indent. So basically this error says:

- You have an indented block without a ":" before it.

Example:

Input:

a = 3
  a += 3

Output:

  File "<stdin>", line 2
    a += 3
    ^
IndentationError: unexpected indent

The output states that he wasn't expecting an indent block line 2, then you should remove it.

3. "TabError: inconsistent use of tabs and spaces in indentation" (python3.x only)

• You can get some info here.
• But basically it's, you are using tabs and spaces in your code.
• You don't want that.
• Remove all tabs and replaces them by four spaces.
• And configure your editor to do that automatically.

Just look at the line number of the error, and fix it using the previous information.

I had a similar issue where visual studio keeps loading symbol and got stuck.

It turns out I added some "Command line arguments" in the Debug options, and one of the parameters is invalid(I am supposed to pass in some values).

After I remove the extra parameter, it starts working again.

both seem to be working.

I Got the Solution Guys

You need to keep some points in your mind .

1. There are two different dependency one is (poi) & other dependency is (poi- ooxml) but make sure you must use poi-ooxml dependency in your code.

2. Just Add the following dependency in pom.xml & Save it.

<dependency>
  <groupId>org.apache.poi</groupId>
  <artifactId>poi-ooxml</artifactId>
  <version>3.9</version>
  </dependency>

3 .After you have saved the pom.xml then you need to try a small thing ,Use (.) operator will try to import/fetch it & finally will not see any sort of error because now it has imported that thing in your package.

Sample Code to Understand Better !!

package ReadFile;// package   
import org.apache.poi.xssf.usermodel.XSSFWorkbook;  // automatically added to your code after importing
public class Test          
{  
public static void Hello() // Method  
{  
XSSFWorkbook workbook = new XSSFWorkbook();   
}  
}

I tried my best to give you the solution , If you face any issue comment here i will try
to solve it .

Keep Learning Guys !!

Gif's can also be displayed in web view with couple of lines of code and without any 3rd party libraries. This way you can even load the gif from your SD card. No need to copy images to your Asset folder.

Take a web view.

<WebView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/imageWebView" />

Use can open a gif file from SD card not just from asset folder as shown in many examples.

    WebView webView = (WebView) findViewById(R.id.imageWebView);
    String  data    = "<body> <img src = \""+ filePath+"\"/></body>";
    // 'filePath' is the path of your .GIF file on SD card.
   webView.loadDataWithBaseURL("file:///android_asset/",data,"text/html","UTF-8",null);

The underscore is the wildcard in a LIKE query for one arbitrary character.

Hence LIKE %_% means "give me all records with at least one arbitrary character in this column".

You have to escape the wildcard character, in sql-server with [] around:

SELECT m.* 
FROM Manager m 
WHERE m.managerid    LIKE  '[_]%'
AND   m.managername  LIKE '%[_]%'

See: LIKE (Transact-SQL)

This should do the trick:

df[- grep("REVERSE", df$Name),]

Or a safer version would be:

df[!grepl("REVERSE", df$Name),]

The problem for me was the cuDNN library which didn't match the requirements of the graphics card. I downloaded the 6.0 version but for my GTX980ti but the recommended compute capability on the nvidia website was 5.1 ( http://developer.nvidia.com/cuda-gpus ) so I downloaded 5.1 and replaced the 6.0 version and as soon as I've done that it started working.

For prevent form from submittion you only need to do this.

<form onsubmit="event.preventDefault()">
    .....
</form>

By using above code this will prevent your form submittion.

In my case, Unity turned out to be a red herring. My problem was a result of different projects targeting different versions of .NET. Unity was set up right and everything was registered with the container correctly. Everything compiled fine. But the type was in a class library, and the class library was set to target .NET Framework 4.0. The WebApi project using Unity was set to target .NET Framework 4.5. Changing the class library to also target 4.5 fixed the problem for me.

I discovered this by commenting out the DI constructor and adding default constructor. I commented out the controller methods and had them throw NotImplementedException. I confirmed that I could reach the controller, and seeing my NotImplementedException told me it was instantiating the controller fine. Next, in the default constructor, I manually instantiated the dependency chain instead of relying on Unity. It still compiled, but when I ran it the error message came back. This confirmed for me that I still got the error even when Unity was out of the picture. Finally, I started at the bottom of the chain and worked my way up, commenting out one line at a time and retesting until I no longer got the error message. This pointed me in the direction of the offending class, and from there I figured out that it was isolated to a single assembly.

In addition to Commons Lang, you can do this with Guava's method Ints.toArray(Collection<Integer> collection):

List<Integer> list = ...
int[] ints = Ints.toArray(list);

This saves you having to do the intermediate array conversion that the Commons Lang equivalent requires yourself.

If you're using node later than 7.6 and you don't like the callback style, you can also use node-util's promisify function with async / await to get shell commands which read cleanly. Here's an example of the accepted answer, using this technique:

const { promisify } = require('util');
const exec = promisify(require('child_process').exec)

module.exports.getGitUser = async function getGitUser () {
  const name = await exec('git config --global user.name')
  const email = await exec('git config --global user.email')
  return { name, email }
};

This also has the added benefit of returning a rejected promise on failed commands, which can be handled with try / catch inside the async code.

Regshot deserves a mention here. It scans and takes a snapshot of all registry settings, then you run it again at a later time to compare with the original snapshot, and it shows you all the keys and values that have changed.

Follow the methods below:

public static int getWidthScreen(Context context) {
    return getDisplayMetrics(context).widthPixels;
}

public static int getHeightScreen(Context context) {
    return getDisplayMetrics(context).heightPixels;
}

private static DisplayMetrics getDisplayMetrics(Context context) {
    DisplayMetrics displayMetrics = new DisplayMetrics();
    WindowManager wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
    wm.getDefaultDisplay().getMetrics(displayMetrics);
    return displayMetrics;
}

As far as I know, the most pythonic/efficient method would be:

Good question with a simple answer: you can't!

Javascript is a client-side programming language, therefore it works on the client's machine, so you can't actually hide anything from the client.
Obfuscating your code is a good solution, but it's not enough, because, although it is hard, someone could decipher your code and "steal" your script.
There are a few ways of making your code hard to be stolen, but as i said nothing is bullet-proof.

Off the top of my head, one idea is to restrict access to your external js files from outside the page you embed your code in. In that case, if you have

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

and someone tries to access the myJs.js file in browser, he shouldn't be granted any access to the script source.
For example, if your page is written in php, you can include the script via the include function and let the script decide if it's safe" to return it's source.
In this example, you'll need the external "js" (written in php) file myJs.php :

<?php
    $URL = $_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'];
    if ($URL != "my-domain.com/my-page.php")
    die("/\*sry, no acces rights\*/");
?>
// your obfuscated script goes here

that would be included in your main page my-page.php :

<script type="text/javascript">
    <?php include "myJs.php"; ?>;
</script> 

This way, only the browser could see the js file contents.

Another interesting idea is that at the end of your script, you delete the contents of your dom script element, so that after the browser evaluates your code, the code disappears :

<script id="erasable" type="text/javascript">
    //your code goes here
    document.getElementById('erasable').innerHTML = "";
</script>

These are all just simple hacks that cannot, and I can't stress this enough : cannot, fully protect your js code, but they can sure piss off someone who is trying to "steal" your code.

Update:

I recently came across a very interesting article written by Patrick Weid on how to hide your js code, and he reveals a different approach: you can encode your source code into an image! Sure, that's not bullet proof either, but it's another fence that you could build around your code.
The idea behind this approach is that most browsers can use the canvas element to do pixel manipulation on images. And since the canvas pixel is represented by 4 values (rgba), each pixel can have a value in the range of 0-255. That means that you can store a character (actual it's ascii code) in every pixel. The rest of the encoding/decoding is trivial.
Thanks, Patrick!

When you want to zoom out a web page to fit it into the iframe size:

1. You should resize the iframe to fit it with the content
2. Then you should zoom out the whole iframe with the loaded web page content

Here is an example:

<div id="wrap">
   <IFRAME ID="frame" name="Main" src ="http://www.google.com" />
</div>

<style type="text/css">
    #wrap { width: 130px; height: 130px; padding: 0; overflow: hidden; }
    #frame { width: 900px; height: 600px; border: 1px solid black; }
    #frame { zoom:0.15; -moz-transform:scale(0.15);-moz-transform-origin: 0 0; }
</style>

Here is a fast and highly readable way to get the min date value

Note: This is a Deterministic Function, so to improve performance further we might as well apply WITH SCHEMABINDING to the return value.

Create a function

CREATE FUNCTION MinDate()
RETURNS DATETIME WITH SCHEMABINDING
AS
BEGIN
    RETURN CONVERT(DATETIME, -53690)

END

Call the function

dbo.MinDate()

Example 1

PRINT dbo.MinDate()

Example 2

PRINT 'The minimimum date allowed in an SQL database is ' + CONVERT(VARCHAR(MAX), dbo.MinDate())

Example 3

SELECT * FROM Table WHERE DateValue > dbo.MinDate()

Example 4

SELECT dbo.MinDate() AS MinDate

Example 5

DECLARE @MinDate AS DATETIME = dbo.MinDate()

SELECT @MinDate AS MinDate

Since your top level view already has android:background property set, you can use a <layer-list> (link) to create a new XML drawable that combines both your old background and your new rounded corners background.

Each <item> element in the list is drawn over the next, so the last item in the list is the one that ends up on top.

<?xml version="1.0" encoding="utf-8"?>
<layer-list
    xmlns:android="http://schemas.android.com/apk/res/android" >
    <item>
        <bitmap android:src="@drawable/mydialogbox" />
    </item>
    <item>
        <shape>
            <stroke
                android:width="1dp"
                android:color="@color/common_border_color" />

            <solid android:color="#ffffff" />

            <padding
                    android:left="1dp"
                    android:right="1dp"
                    android:top="1dp" />

            <corners android:radius="5dp" />
        </shape>
    </item>
</layer-list>

Your http is being blocked by a firewall from F5 Networks called Application Security Manager (ASM). It produces messages like:

Please consult with your administrator.
Your support ID is: xxxxxxxxxxxx

So your application is passing some data that for some reason ASM detects as a threat. Give the support id to you network engineer to learn the specific reason.

Increase the font-size of glyphicon to increase all icons size.

.glyphicon {

}

I just found the "-fae" parameter, which causes Maven to run all tests and not stop on failure.

You can load data from a csv or text file. If you have a text file with records from a table, you can load those records within the table. For example if you have a text file, where each row is a record with the values for each column, you can load the records this way.

table.sql

id //field 1

name //field2

table.txt

1,peter

2,daniel

...

--example on windows

LOAD DATA LOCAL INFILE 'C:\\directory_example\\table.txt'
INTO TABLE Table
CHARACTER SET UTF8
FIELDS TERMINATED BY ','
LINES TERMINATED BY '\r\n'; 

Before this line at main.js:

mainWindow = new BrowserWindow({width: 800, height: 900})

mainWindow.setMenu(null) //this will r menu bar

Use this command:

ls -ltr /mig/mthome/09/log/*

instead of:

ls -ltr /mig/mthome/09/log

to get the full path in the listing.

In the designer, you just need to set the ForeColor property to whatever color you'd like. In the case of Red, there's a predefined color for it.

To do it in code (C#) do this:

pgs.ForeColor = Color.Red;

Edit: Oh yeah, also set the Style to continuous. In code, like this:

pgs.Style = System.Windows.Forms.ProgressBarStyle.Continuous;

Another Edit: You'll also need to remove the line that reads Application.EnableVisualStyles() from your Program.cs (or similar). If you can't do this because you want the rest of the application to have visual styles, then I'd suggest painting the control yourself or moving on to WPF since this kind of thing is easy with WPF. You can find a tutorial on owner drawing a progress bar on codeplex

In addition, it is also possible to turn logging off programmatically:

Logger.getRootLogger().setLevel(Level.OFF);

Or

Logger.getRootLogger().removeAllAppenders();
Logger.getRootLogger().addAppender(new NullAppender());

These use imports:

import org.apache.log4j.Logger;
import org.apache.log4j.Level;
import org.apache.log4j.NullAppender;

You can use these options as well, either use \footnotesize or \tiny. This would really help in fitting big tables.

\begin{table}[htbp]
\footnotesize
\caption{Information on making the table size small}
\label{table:table1}
\begin{tabular}{ll}
    \toprule
    S.No       & HMD           \\
    \midrule
    1          & HTC Vive \\
    2          & HTC Vive Pro   \\
    \bottomrule
\end{tabular}
\end{table}

From Docker documentation:

docker export does not export the contents of volumes associated with the container. If a volume is mounted on top of an existing directory in the container, docker export will export the contents of the underlying directory, not the contents of the volume. Refer to Backup, restore, or migrate data volumes in the user guide for examples on exporting data in a volume.

If you're looking for "in-place" editing of a ListView's contents (specifically the subitems of a ListView in details view mode), you'll need to implement this yourself, or use a third-party control.

By default, the best you can achieve with a "standard" ListView is to set it's LabelEdit property to true to allow the user to edit the text of the first column of the ListView (assuming you want to allow a free-format text edit).

Some examples (including full source-code) of customized ListView's that allow "in-place" editing of sub-items are:

C# Editable ListView

This is generic code for configuration collection :

public class GenericConfigurationElementCollection<T> :   ConfigurationElementCollection, IEnumerable<T> where T : ConfigurationElement, new()
{
    List<T> _elements = new List<T>();

    protected override ConfigurationElement CreateNewElement()
    {
        T newElement = new T();
        _elements.Add(newElement);
        return newElement;
    }

    protected override object GetElementKey(ConfigurationElement element)
    {
        return _elements.Find(e => e.Equals(element));
    }

    public new IEnumerator<T> GetEnumerator()
    {
        return _elements.GetEnumerator();
    }
}

After you have GenericConfigurationElementCollection, you can simple use it in the config section (this is an example from my Dispatcher):

public class  DispatcherConfigurationSection: ConfigurationSection
{
    [ConfigurationProperty("maxRetry", IsRequired = false, DefaultValue = 5)]
    public int MaxRetry
    {
        get
        {
            return (int)this["maxRetry"];
        }
        set
        {
            this["maxRetry"] = value;
        }
    }

    [ConfigurationProperty("eventsDispatches", IsRequired = true)]
    [ConfigurationCollection(typeof(EventsDispatchConfigurationElement), AddItemName = "add", ClearItemsName = "clear", RemoveItemName = "remove")]
    public GenericConfigurationElementCollection<EventsDispatchConfigurationElement> EventsDispatches
    {
        get { return (GenericConfigurationElementCollection<EventsDispatchConfigurationElement>)this["eventsDispatches"]; }
    }
}

The Config Element is config Here:

public class EventsDispatchConfigurationElement : ConfigurationElement
{
    [ConfigurationProperty("name", IsRequired = true)]
    public string Name
    {
        get
        {
            return (string) this["name"];
        }
        set
        {
            this["name"] = value;
        }
    }
}

The config file would look like this:

<?xml version="1.0" encoding="utf-8" ?>
  <dispatcherConfigurationSection>
    <eventsDispatches>
      <add name="Log" ></add>
      <add name="Notification" ></add>
      <add name="tester" ></add>
    </eventsDispatches>
  </dispatcherConfigurationSection>

Hope it help !

Depends

It depends on various things. But in general algorithms using a Divide-and-Conquer / dichotomic approach will perform well for sorting problems as they present interesting average-case complexities.

Basics

To understand which algorithms work best, you will need basic knowledge of algorithms complexity and big-O notation, so you can understand how they rate in terms of average case, best case and worst case scenarios. If required, you'd also have to pay attention to the sorting algorithm's stability.

For instance, usually an efficient algorithm is quicksort. However, if you give quicksort a perfectly inverted list, then it will perform poorly (a simple selection sort will perform better in that case!). Shell-sort would also usually be a good complement to quicksort if you perform a pre-analysis of your list.

Have a look at the following, for "advanced searches" using divide and conquer approaches:

• quicksort
• shellsort
• mergesort

And these more straighforward algorithms for less complex ones:

• bubblesort
• selection sort
• insert sort

Further

The above are the usual suspects when getting started, but there are countless others.

As pointed out by R. in the comments and by kriss in his answer, you may want to have a look at HeapSort, which provides a theoretically better sorting complexity than a quicksort (but will won't often fare better in practical settings). There are also variants and hybrid algorithms (e.g. TimSort).

You can use below command

alter database Testing modify name=LearningSQL;

Old Database Name = Testing, New Database Name = LearningSQL

With Windows 8, Microsoft introduced the Windows Desktop Duplication API. That is the officially recommended way of doing it. One nice feature it has for screencasting is that it detects window movement, so you can transmit block deltas when windows get moved around, instead of raw pixels. Also, it tells you which rectangles have changed, from one frame to the next.

The Microsoft example code is pretty complex, but the API is actually simple and easy to use. I've put together an example project which is much simpler than the official example:

https://github.com/bmharper/WindowsDesktopDuplicationSample

Docs: https://docs.microsoft.com/en-gb/windows/desktop/direct3ddxgi/desktop-dup-api

Microsoft official example code: https://code.msdn.microsoft.com/windowsdesktop/Desktop-Duplication-Sample-da4c696a

I was facing an issue with PJSIP libraries,

Tried the following in other linker flags in project and able to resolve the error: -framework Foundation -framework UIKit

Above linker flags are used in Siphone Project over github. These settings will help you resolve problems related to linking of C++ libraries.

This depends on what you're actually trying to do.

If you simply wish to apply styles to a :before pseudo-element when the a element matches a pseudo-class, you need to write a:hover:before or a:visited:before instead. Notice the pseudo-element comes after the pseudo-class (and in fact, at the very end of the entire selector). Notice also that they are two different things; calling them both "pseudo-selectors" is going to confuse you once you run into syntax problems such as this one.

If you're writing CSS3, you can denote a pseudo-element with double colons to make this distinction clearer. Hence, a:hover::before and a:visited::before. But if you're developing for legacy browsers such as IE8 and older, then you can get away with using single colons just fine.

This specific order of pseudo-classes and pseudo-elements is stated in the spec:

One pseudo-element may be appended to the last sequence of simple selectors in a selector.

A sequence of simple selectors is a chain of simple selectors that are not separated by a combinator. It always begins with a type selector or a universal selector. No other type selector or universal selector is allowed in the sequence.

A simple selector is either a type selector, universal selector, attribute selector, class selector, ID selector, or pseudo-class.

A pseudo-class is a simple selector. A pseudo-element, however, is not, even though it resembles a simple selector.

However, for user-action pseudo-classes such as :hover¹, if you need this effect to apply only when the user interacts with the pseudo-element itself but not the a element, then this is not possible other than through some obscure layout-dependent workaround. As implied by the text, standard CSS pseudo-elements cannot currently have pseudo-classes. In that case, you will need to apply :hover to an actual child element instead of a pseudo-element.

¹ _{Of course, this does not apply to link pseudo-classes such as :visited as in the question, since pseudo-elements aren't links.}

File -> Export -> Web -> WAR file

OR in Kepler follow as shown below :

Change the <td> to be split to look like this:

<td><table><tr><td>split 1</td><td>split 2</td></tr></table></td> 

You can use $addToSet with the aggregation framework to count distinct objects.

For example:

db.collectionName.aggregate([{
    $group: {_id: null, uniqueValues: {$addToSet: "$fieldName"}}
}])

Yes, there is.

Surprising, huh? You can get a specific value from a multiple return using a simple mute function:

package main

import "fmt"
import "strings"

func µ(a ...interface{}) []interface{} {
    return a
}

type A struct {
    B string
    C func()(string)
}

func main() {
    a := A {
        B:strings.TrimSpace(µ(E())[1].(string)),
        C:µ(G())[0].(func()(string)),
    }

    fmt.Printf ("%s says %s\n", a.B, a.C())
}

func E() (bool, string) {
    return false, "F"
}

func G() (func()(string), bool) {
    return func() string { return "Hello" }, true
}

https://play.golang.org/p/IwqmoKwVm-

Notice how you select the value number just like you would from a slice/array and then the type to get the actual value.

You can read more about the science behind that from this article. Credits to the author.

All the solutions provided force you to know the element you will click beforehand. If you want to get the class from any element clicked you can use:

$(document).on('click', function(e) {
    clicked_id = e.target.id;
    clicked_class = $('#' + e.target.id).attr('class');
    // do stuff with ids and classes 
    })

Is there something that prevents you from merging all revisions on trunk since the last merge?

svn merge -rLastRevisionMergedFromTrunkToBranch:HEAD url/of/trunk path/to/branch/wc

should work just fine. At least if you want to merge all changes on trunk to your branch.

I think it's worth putting a few timings up here for some perspective.

All timings done on OS-X 10.5.8 with python2.7

John Clement's answer:

python -m timeit -s 'my_list = range(1000)[::-1]; from operator import itemgetter' 'min(enumerate(my_list),key=itemgetter(1))'
1000 loops, best of 3: 239 usec per loop    

David Wolever's answer:

python -m timeit -s 'my_list = range(1000)[::-1]' 'min((val, idx) for (idx, val) in enumerate(my_list))
1000 loops, best of 3: 345 usec per loop

OP's answer:

python -m timeit -s 'my_list = range(1000)[::-1]' 'my_list.index(min(my_list))'
10000 loops, best of 3: 96.8 usec per loop

Note that I'm purposefully putting the smallest item last in the list to make .index as slow as it could possibly be. It would be interesting to see at what N the iterate once answers would become competitive with the iterate twice answer we have here.

Of course, speed isn't everything and most of the time, it's not even worth worrying about ... choose the one that is easiest to read unless this is a performance bottleneck in your code (and then profile on your typical real-world data -- preferably on your target machines).

Sometimes the thread execution process time is higher than JVM thread waiting process time, it use to happen when the process you're invoking takes some time to be processed, use the waitFor() command as follows:

try{    
    Process p = Runtime.getRuntime().exec("file location here, don't forget using / instead of \\ to make it interoperable");
    p.waitFor();

}catch( IOException ex ){
    //Validate the case the file can't be accesed (not enought permissions)

}catch( InterruptedException ex ){
    //Validate the case the process is being stopped by some external situation     

}

This way the JVM will stop until the process you're invoking is done before it continue with the thread execution stack.

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.

Set the scrollable div to have a max-size and add overflow-y: scroll; to it's properties.

Edit: trying to get the jsfiddle to work, but it's not scrolling properly. This will take some time to figure out.

The Random class of Java located in the java.util package will serve your purpose better. It has some nextInt() methods that return an integer. The one taking an int argument will generate a number between 0 and that int, the latter not inclusive.

Well, I don't know guys but:

using here python 3.6 and django 2.2

Renaming MIDDLEWARE_CLASSES to MIDDLEWARE in settings.py worked.

If you need to do this on the backend you can use the following URL structure:

https://maps.googleapis.com/maps/api/geocode/json?address=[STREET_ADDRESS]&key=[YOUR_API_KEY]

Sample PHP code using curl:

$curl = curl_init();

curl_setopt($curl, CURLOPT_URL, 'https://maps.googleapis.com/maps/api/geocode/json?address=' . rawurlencode($address) . '&key=' . $api_key);

curl_setopt ($curl, CURLOPT_RETURNTRANSFER, 1);

$json = curl_exec($curl);

curl_close ($curl);

$obj = json_decode($json);

See additional documentation for more details and expected json response.

The docs provide sample output and will assist you in getting your own API key in order to be able to make requests to the Google Maps Geocoding API.

The problem obviously was (as you figured it out) that port 36250 wasn't open on the server side at the time you tried to connect (hence connection refused). I can see the server was supposed to open this socket after receiving SEND command on another connection, but it apparently was "not opening [it] up in sync with the client side".

Well, the main reason would be there was no synchronisation whatsoever. Calling:

cs.send("SEND " + FILE)
cs.close()

would just place the data into a OS buffer; close would probably flush the data and push into the network, but it would almost certainly return before the data would reach the server. Adding sleep after close might mitigate the problem, but this is not synchronisation.

The correct solution would be to make sure the server has opened the connection. This would require server sending you some message back (for example OK, or better PORT 36250 to indicate where to connect). This would make sure the server is already listening.

The other thing is you must check the return values of send to make sure how many bytes was taken from your buffer. Or use sendall.

(Sorry for disturbing with this late answer, but I found this to be a high traffic question and I really didn't like the sleep idea in the comments section.)

For me this works,

<td width="170px" style="word-wrap:break-word;">
  <div style="width:140px;overflow:auto">
    LONGTEXTGOESHERELONGDIVGOESLONGTEXTGOESLONGTEXTGOESLONGTEXTGOESLONGTEXTGOESLONGTEXTGOESLONGTEXTGOESLONGTEXTGOESLONGTEXTGOESLONGTEXTGOESLONGTEXTGOESLONGTEXTGOESLONGTEXTGOESLONGTEXTGOESLONGTEXTGOESLONGTEXTGOESLONGTEXTGOESLONGTEXTGOESLONGTEXTGOESLONGTEXTGOESLONGTEXTGOESLONGTEXTGOESLONGTEXTGOESLONGTEXTGOESLONGTEXTGOESLONGTEXTGOESLONGTEXTGOESHERELONGDIVLONGTEXTLONGTEXT
  </div>
</td>

You can also use a div inside another div instead of td. I used overflow:auto, as it shows all the text both in my Opera and IE browsers.

As of ISO7 at least you can easily do this with NSJSONSerialization.

Roughly, partial does something like this (apart from keyword args support etc):

def partial(func, *part_args):
    def wrapper(*extra_args):
        args = list(part_args)
        args.extend(extra_args)
        return func(*args)

    return wrapper

So, by calling partial(sum2, 4) you create a new function (a callable, to be precise) that behaves like sum2, but has one positional argument less. That missing argument is always substituted by 4, so that partial(sum2, 4)(2) == sum2(4, 2)

As for why it's needed, there's a variety of cases. Just for one, suppose you have to pass a function somewhere where it's expected to have 2 arguments:

class EventNotifier(object):
    def __init__(self):
        self._listeners = []

    def add_listener(self, callback):
        ''' callback should accept two positional arguments, event and params '''
        self._listeners.append(callback)
        # ...

    def notify(self, event, *params):
        for f in self._listeners:
            f(event, params)

But a function you already have needs access to some third context object to do its job:

def log_event(context, event, params):
    context.log_event("Something happened %s, %s", event, params)

So, there are several solutions:

A custom object:

class Listener(object):
   def __init__(self, context):
       self._context = context

   def __call__(self, event, params):
       self._context.log_event("Something happened %s, %s", event, params)


 notifier.add_listener(Listener(context))

Lambda:

log_listener = lambda event, params: log_event(context, event, params)
notifier.add_listener(log_listener)

With partials:

context = get_context()  # whatever
notifier.add_listener(partial(log_event, context))

Of those three, partial is the shortest and the fastest. (For a more complex case you might want a custom object though).

For versions earlier than JPA 2.1, JPA provides only two ways to deal with enums, by their name or by their ordinal. And the standard JPA doesn't support custom types. So:

• If you want to do custom type conversions, you'll have to use a provider extension (with Hibernate UserType, EclipseLink Converter, etc). (the second solution). ~or~
• You'll have to use the @PrePersist and @PostLoad trick (the first solution). ~or~
• Annotate getter and setter taking and returning the int value ~or~
• Use an integer attribute at the entity level and perform a translation in getters and setters.

I'll illustrate the latest option (this is a basic implementation, tweak it as required):

@Entity
@Table(name = "AUTHORITY_")
public class Authority implements Serializable {

    public enum Right {
        READ(100), WRITE(200), EDITOR (300);

        private int value;

        Right(int value) { this.value = value; }    

        public int getValue() { return value; }

        public static Right parse(int id) {
            Right right = null; // Default
            for (Right item : Right.values()) {
                if (item.getValue()==id) {
                    right = item;
                    break;
                }
            }
            return right;
        }

    };

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name = "AUTHORITY_ID")
    private Long id;

    @Column(name = "RIGHT_ID")
    private int rightId;

    public Right getRight () {
        return Right.parse(this.rightId);
    }

    public void setRight(Right right) {
        this.rightId = right.getValue();
    }

}

First of all, the easiest way to run things at startup is to add them to the file /etc/rc.local.

Another simple way is to use @reboot in your crontab. Read the cron manpage for details.

However, if you want to do things properly, in addition to adding a script to /etc/init.d you need to tell ubuntu when the script should be run and with what parameters. This is done with the command update-rc.d which creates a symlink from some of the /etc/rc* directories to your script. So, you'd need to do something like:

update-rc.d yourscriptname start 2

However, real init scripts should be able to handle a variety of command line options and otherwise integrate to the startup process. The file /etc/init.d/README has some details and further pointers.

Depending on the file which will be put into filesystem, as long as that file is not a malware, then that would be safe.

But don't worry to write/read file(s) to File System directory, cause you can tighten that directory security (include it's inheritance) by give a proper access right and security restriction. eg: read/write/modify.

By default, File System, Local Storage, and Storage directory are located on "\Users[Current User]\AppData\Local\Google\Chrome\User Data\Default" directory.

However you can customize it by using "--user-data-dir" flag.

And this is a sample:

"C:\Program Files (x86)\Google\Application\chrome.exe" --user-data-dir="C:\Chrome_Data\OO7" --allow-file-access-from-files

Hope this helps anyone.

If you are using the GET request to actually SEND data...

The problem with MSXML2.XMLHTTP is that there are several versions of it, with different names depending on the windows os version and patches.

this explains it: http://support.microsoft.com/kb/269238

i have had more luck using vbscript to call

set ID = CreateObject("InternetExplorer.Application")
IE.visible = 0
IE.navigate "http://example.com/parser.php?key=" & value & "key2=" & value2 
do while IE.Busy.... 

....and more stuff but just to let the request go thru.

select *  
from TABLE_NAME
where dbms_lob.instr(COLUMNNAME,'searchtext') > 0;

try this:

grep -P '^(tomcat!?)' tst1.txt

It will search for specific word in txt file. Here we are trying to search word tomcat

The LIMIT clause is not part of standard SQL. It's supported as a vendor extension to SQL by MySQL, PostgreSQL, and SQLite.

Other brands of database may have similar features (e.g. TOP in Microsoft SQL Server), but these don't always work identically.

It's hard to use TOP in Microsoft SQL Server to mimic the LIMIT clause. There are cases where it just doesn't work.

The solution you showed, using ROW_NUMBER() is available in Microsoft SQL Server 2005 and later. This is the best solution (for now) that works solely as part of the query.

Another solution is to use TOP to fetch the first count + offset rows, and then use the API to seek past the first offset rows.

• "Emulate MySQL LIMIT clause in Microsoft SQL Server 2000"
• "Paging of Large Resultsets in ASP.NET"

You should and must not push to the project with some common credentials. Once starting on a new machine use the following steps to setup and use correctly your gitlab credentials:

• create the pubic / private ssh keys on the machine
• copy paste the public key to the gitlab/github ui interface ( anyone hinting how-to do via the cmd line gets a free beer ... )
• make sure you clone the repo via the git and not http url
• set the git alias to avoid constant typing of the same prefix to the git command
• during git commit ALWAYS use the author and e-mail flags
• use git as normal you would do it

All this as follows:

 # create the public / private key credentials on that specific machine
 ssh-keygen -t rsa -b 4096 -C "<<you>>@org.net" -f ~/.ssh/id_rsa.<<you>>.`hostname -s`

 # setup your public key in the gitlab ui 
 cat ~/.ssh/id_rsa.<<you>>.`hostname -s`

 # make sure you clone the repo via the git and not http url
 git clone [email protected]:org/some-repo.git

 # set the git alias to avoid constant typing of the repeating prefix to the git cmd
 alias git='GIT_SSH_COMMAND="ssh -i ~/.ssh/id_rsa.<<you>>.`hostname -s`" git'

 # during git commit ALWAYS use the author and e-mail flags
 git add --all ; git commit -nm "$git_msg" --author "YourFirstName YourLastName <[email protected]>"

 # use git as normal
 git fetch --all; git pull --all 

You should add fstream::out to open method like this:

file.open("test.txt",fstream::out);

More information about fstream flags, check out this link: http://www.cplusplus.com/reference/fstream/fstream/open/

I wrote a little helper function that works with any select. All you need to do is add the class "redirectOnChange" to any select element, and this will cause the page to reload with a new/changed querystring parameter, equal to the id and value of the select, e.g:

<select id="myValue" class="redirectOnChange"> 
    <option value="222">test222</option>
    <option value="333">test333</option>
</select>

The above example would add "?myValue=222" or "?myValue=333" (or using "&" if other params exist), and reload the page.

jQuery:

$(document).ready(function () {

    //Redirect on Change
    $(".redirectOnChange").change(function () {
        var href = window.location.href.substring(0, window.location.href.indexOf('?'));
        var qs = window.location.href.substring(window.location.href.indexOf('?') + 1, window.location.href.length);
        var newParam = $(this).attr("id") + '=' + $(this).val();

        if (qs.indexOf($(this).attr("id") + '=') == -1) {
            if (qs == '') {
                qs = '?'
            }
            else {
                qs = qs + '&'
            }
            qs = qs + newParam;

        }
        else {
            var start = qs.indexOf($(this).attr("id") + "=");
            var end = qs.indexOf("&", start);
            if (end == -1) {
                end = qs.length;
            }
            var curParam = qs.substring(start, end);
            qs = qs.replace(curParam, newParam);
        }
        window.location.replace(href + '?' + qs);
    });
});

What your looking for is the DefaultListModel - Dynamic String List Variable.

Here is a whole class that uses the DefaultListModel as though it were the TStringList of Delphi. The difference is that you can add Strings to the list without limitation and you have the same ability at getting a single entry by specifying the entry int.

FileName: StringList.java

package YOUR_PACKAGE_GOES_HERE;

//This is the StringList Class by i2programmer
//You may delete these comments
//This code is offered freely at no requirements
//You may alter the code as you wish
import java.io.File;
import java.io.FileReader;
import java.io.FileWriter;
import java.io.IOException;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.swing.DefaultListModel;

public class StringList {

    public static String OutputAsString(DefaultListModel list, int entry) {
        return GetEntry(list, entry);
    }

    public static Object OutputAsObject(DefaultListModel list, int entry) {
        return GetEntry(list, entry);
    }

    public static int OutputAsInteger(DefaultListModel list, int entry) {
        return Integer.parseInt(list.getElementAt(entry).toString());
    }

    public static double OutputAsDouble(DefaultListModel list, int entry) {
        return Double.parseDouble(list.getElementAt(entry).toString());
    }

    public static byte OutputAsByte(DefaultListModel list, int entry) {
        return Byte.parseByte(list.getElementAt(entry).toString());
    }

    public static char OutputAsCharacter(DefaultListModel list, int entry) {
        return list.getElementAt(entry).toString().charAt(0);
    }

    public static String GetEntry(DefaultListModel list, int entry) {
        String result = "";
        result = list.getElementAt(entry).toString();
        return result;
    }

    public static void AddEntry(DefaultListModel list, String entry) {
        list.addElement(entry);
    }

    public static void RemoveEntry(DefaultListModel list, int entry) {
        list.removeElementAt(entry);
    }

    public static DefaultListModel StrToList(String input, String delimiter) {
        DefaultListModel dlmtemp = new DefaultListModel();
        input = input.trim();
        delimiter = delimiter.trim();
        while (input.toLowerCase().contains(delimiter.toLowerCase())) {
            int index = input.toLowerCase().indexOf(delimiter.toLowerCase());
            dlmtemp.addElement(input.substring(0, index).trim());
            input = input.substring(index + delimiter.length(), input.length()).trim();
        }
        return dlmtemp;
    }

    public static String ListToStr(DefaultListModel list, String delimiter) {
        String result = "";
        for (int i = 0; i < list.size(); i++) {
            result = list.getElementAt(i).toString() + delimiter;
        }
        result = result.trim();
        return result;
    }

    public static String LoadFile(String inputfile) throws IOException {
        int len;
        char[] chr = new char[4096];
        final StringBuffer buffer = new StringBuffer();
        final FileReader reader = new FileReader(new File(inputfile));
        try {
            while ((len = reader.read(chr)) > 0) {
                buffer.append(chr, 0, len);
            }
        } finally {
            reader.close();
        }
        return buffer.toString();
    }

    public static void SaveFile(String outputfile, String outputstring) {
        try {
            FileWriter f0 = new FileWriter(new File(outputfile));
            f0.write(outputstring);
            f0.flush();
            f0.close();
        } catch (IOException ex) {
            Logger.getLogger(StringList.class.getName()).log(Level.SEVERE, null, ex);
        }
    }
}

OutputAs methods are for outputting an entry as int, double, etc... so that you don't have to convert from string on the other side.

SaveFile & LoadFile are to save and load strings to and from files.

StrToList & ListToStr are to place delimiters between each entry.

ex. 1<>2<>3<>4<> if "<>" is the delimiter and 1 2 3 & 4 are the entries.

AddEntry & GetEntry are to add and get strings to and from the DefaultListModel.

RemoveEntry is to delete a string from the DefaultListModel.

You use the DefaultListModel instead of an array here like this:

DefaultListModel list = new DefaultListModel();
//now that you have a list, you can run it through the above class methods.

I think lock-free alternatives to standard data structures i.e lock-free queue, stack and list are much overlooked.
They are increasingly relevant as concurrency becomes a higher priority and are much more admirable goal than using Mutexes or locks to handle concurrent read/writes.

Here's some links

Mike Acton's (often provocative) blog has some excellent articles on lock-free design and approaches

If you indeed wanna use scp, there's a indirect way.Say we want to copy all .jpg file under local folder '/src' to folder '/dst' in remote server 10.1.1.2:

#make a clean temp folder
mkdir /tmp/ttt
#copy all .jpg file and retain folder structure as-is
find /src -type f -name *.jpg -exec cp --parents \{\} /tmp/ttt \;
#copy to remote target folder as-is and retain original time attributes
scp -rp /tmp/ttt/* 10.1.1.2:/dst
#if copy ok, remove temp folder
rm -rf /tmp/ttt

Here is an overview of how the .NET framework and compiler versions are related, set and modified. Each project has a target .NET framework version(s), for example version 3.x or 2.x . The .NET framework contains the run time types and components.

The Visual Studio version installation and the .NET framework version determine the compatible c# language version and compiler options that can be used. The default c# version and options used in a Visual Studio project is the latest language version installed that is compatible with the .NET framework version being used.

To view or update the Framework or C# language within a project within Visual Studio 2011:

• right click the project within Solution Explorer and select Properties

• select 'Application' in the left navigation pane. Under Target framework: is the .NET framework version. Select the down arrow to see all available framework versions.

• select 'Build' in the left navigation pane. In the 'General' section of the pane next to 'Language Version:' is the c# compiler language version being used, for example 'default' or c# 5.0

• select the down arrow in the 'Language Version:" dropdown to see all available language versions. If 'default' is the c# version being used, the latest compatible c# language version will be used.

To see the exact compiler language version for 'default', enter the following in the developer command prompt for your installed Visual Studio version. For example, from the Windows Start icon select icon: "Developer Command Prompt for VS2011' and enter:

csc -langversion:Default

Microsoft (R) Visual C# Compiler version 4.7.3062.0 for c# 5

I had this same issue and a couple others being reported for a existing maven project.

I had the proper dependencies in place and I could see the jar under maven dependencies, however the project was improperly brought into eclipse.

I ended up having to delete the project, clone from git again then do an import of the project as an existing maven project.

This solved the issue in this thread and several others issues I was having. More details on solution can be found here: Maven Project in Eclipse `org.springframework cannot be resolved to a type` from target path

Most of the answers are in jquery. You can do this perfectly in pure Javascript, simple and no library required. Here it is:

<script type="text/javascript">
window.addEventListener('keydown',function(e){if(e.keyIdentifier=='U+000A'||e.keyIdentifier=='Enter'||e.keyCode==13){if(e.target.nodeName=='INPUT'&&e.target.type=='text'){e.preventDefault();return false;}}},true);
</script>

This code works great because, it only disables the "Enter" keypress action for input type='text'. This means visitors are still able to use "Enter" key in textarea and across all of the web page. They will still be able to submit the form by going to the "Submit" button with "Tab" keys and hitting "Enter".

Here are some highlights:

1. It is in pure javascript (no library required).
2. Not only it checks the key pressed, it confirms if the "Enter" is hit on the input type='text' form element. (Which causes the most faulty form submits
3. Together with the above, user can use "Enter" key anywhere else.
4. It is short, clean, fast and straight to the point.

If you want to disable "Enter" for other actions as well, you can add console.log(e); for your your test purposes, and hit F12 in chrome, go to "console" tab and hit "backspace" on the page and look inside it to see what values are returned, then you can target all of those parameters to further enhance the code above to suit your needs for "e.target.nodeName", "e.target.type" and many more...

I'd recommend pygit2 - it uses the excellent libgit2 bindings

See the treatment by Dark Otter

https://montemazuma.wordpress.com/2010/03/01/moving-a-gpg-key-privately/

If the site is down use reference the archive.org backup:

https://web.archive.org/web/20170518155052/https://montemazuma.wordpress.com/2010/03/01/moving-a-gpg-key-privately/

which includes a reasonably secure way to transfer keys. You could put that recommendation into shell-scripts shown below for repeated use.

First get the KEYID you want from the list shown by

$ gpg -K

From the resulting list note the KEYID (the 8 hexadecimals following sec) you need for transfer.

Then envoke the tested shell scipts "export_private_key" on the first account and generate your pubkey.gpg + keys.asc. Subsequently invoke on the second account "import_private_key". Here is their content shown with cat (copy & paste content):

$ cat export_private_key 
gpg -K
echo "select private key"
read KEYID
gpg --output pubkey.gpg --export $KEYID
echo REMEMBER THE COMING PASS-PHRASE
gpg --output - --export-secret-key $KEYID | \
   cat pubkey.gpg - | \
   gpg --armor --output keys.asc --symmetric --cipher-algo AES256
ls -l pubkey.gpg keys.asc
####################  E X P O R T _ P R I V A T E _ K E Y  #####################

Now tranfer by some means the "pubkey.gpg" (if needed) and the private "keys.asc" to the second account and envoke the below-shown program.

$ cat import_private_key 
gpg --no-use-agent --output - keys.asc | gpg --import
###################  I M P O R T _ P R I V A T E _ K E Y  ######################

In Otter's spirit "And that, should be, that".

You can also use the following format

strtotime("-3 days", time());
strtotime("+1 day", strtotime($date));

You can stack changes this way:

strtotime("+1 day", strtotime("+1 year", strtotime($date)));

Note the difference between this approach and the one in other answers: instead of concatenating the values +1 day and <timestamp>, you can just pass in the timestamp as the second parameter of strtotime.

I have aggregated with Qty wise data and store to dataframe

almo_grp_data = pd.DataFrame({'Qty_cnt' :
almo_slt_models_data.groupby( ['orderDate','Item','State Abv']
          )['Qty'].sum()}).reset_index()

$.ajax({
  url: '//.xml',
  dataType: 'xml',
  success: onTrue,
  error: function (err) {
      console.error('Error: ', err);
  }
});

$('a').each(function () {
  $(this).click(function (e) {
      var l = e.target.text;
      //array.sort(sorteerOp(l));
      //functionToAdaptHtml();
  });
});

Edit: Be a Red ninja:

!!array.reduce(function(a, b){ return (a === b) ? a : NaN; });

Results:

var array = ["a", "a", "a"] => result: "true"
var array = ["a", "b", "a"] => result: "false"
var array = ["false", ""] => result: "false"
var array = ["false", false] => result: "false"
var array = ["false", "false"] => result: "true"
var array = [NaN, NaN] => result: "false" 

Warning:

var array = [] => result: TypeError thrown

This is because we do not pass an initialValue. So, you may wish to check array.length first.

Using Collections#addAll()

String[] words = {"ace","boom","crew","dog","eon"};
List<String> arrayList = new ArrayList<>(); 
Collections.addAll(arrayList, words); 

I stumbled in here looking for a similar answer without the "git log" restriction. The answers here didn't give me what I needed but this did so I'll add it in case others find it useful:

git diff --name-only

You can also couple this with standard commit pointers to see what has changed since a particular commit:

git diff --name-only HEAD~3
git diff --name-only develop
git diff --name-only 5890e37..ebbf4c0

This succinctly provides file names only which is great for scripting. For example:

git diff --name-only develop | while read changed_file; do echo "This changed from the develop version: $changed_file"; done

#OR

git diff --name-only develop | xargs tar cvf changes.tar

I'm using this to address the security implications noted in @CMS's answer.

// example 1: www.example.com/index.html#foo

// load correct subpage from URL hash if it exists
$(window).on('load', function () {
    var hash = window.location.hash;
    if (hash) {
        hash = hash.replace('#',''); // strip the # at the beginning of the string
        hash = hash.replace(/([^a-z0-9]+)/gi, '-'); // strip all non-alphanumeric characters
        hash = '#' + hash; // hash now equals #foo with example 1

        // do stuff with hash
        $( 'ul' + hash + ':first' ).show();
        // etc...
    }
});

Some APIs want you to supply the appropriate "Accept" header in the request to get the wanted response type.

For example if an API can return data in XML and JSON and you want the JSON result, you would need to set the HttpWebRequest.Accept property to "application/json".

HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create(requestUri);
httpWebRequest.Method = WebRequestMethods.Http.Get;
httpWebRequest.Accept = "application/json";

Use minipage environment. Here is an example:

\begin{minipage}{6cm}
\begin{tabular}{|l|c|c|}
    \hline
    A & 1 & 2 \footnote{This is a footnote.} \\
    \hline
    B & 2 & 1 \\
    \hline
    C & 3 & 3 \\
    \hline
\end{tabular}
\end{minipage}

Yes, according to RFC 3696 apostrophes are valid as long as they come before the @ symbol.

You almost had it, just need to escape special regex chars:

regex = /http\:\/\/www\.youtube\.com\/watch\?v=([\w-]{11})/;

url = 'http://www.youtube.com/watch?v=Ahg6qcgoay4';
id = url.match(regex)[1]; // id = 'Ahg6qcgoay4'

Edit: Fix for regex by soupagain.

You could compare String representations so:

array1.toString() == array2.toString()
array1.toString() !== array3.toString()

but that would also make

array4 = ['1',2,3,4,5]

equal to array1 if that matters to you

>> id(1)
1923344848  # identity of the location in memory where 1 is stored
>> id(1)
1923344848  # always the same
>> a = 1
>> b = a  # or equivalently b = 1, because 1 is immutable
>> id(a)
1923344848
>> id(b)  # equal to id(a)
1923344848

As you can see a and b are just two different names that reference to the same immutable object (int) 1. If later you write a = 2, you reassign the name a to a different object (int) 2, but the b continues referencing to 1:

>> id(2)
1923344880
>> a = 2
>> id(a)
1923344880  # equal to id(2)
>> b
1           # b hasn't changed
>> id(b)
1923344848  # equal to id(1)

What would happen if you had a mutable object instead, such as a list [1]?

>> id([1])
328817608
>> id([1])
328664968  # different from the previous id, because each time a new list is created
>> a = [1]
>> id(a)
328817800
>> id(a)
328817800 # now same as before
>> b = a
>> id(b)
328817800  # same as id(a)

Again, we are referencing to the same object (list) [1] by two different names a and b. However now we can mutate this list while it remains the same object, and a, b will both continue referencing to it

>> a[0] = 2
>> a
[2]
>> b
[2]
>> id(a)
328817800  # same as before
>> id(b)
328817800  # same as before

endstring = ''
for s in list:
    endstring += s

What worked for me was a combination of the answers from Nicole Finnie and Ciro Santilli along with some answers from elsewhere.

Setting up the pi

We will need to do two things: activate ssh on the pi, and configure the pi to use a static ip.

Activating ssh

Add a file called ssh in the boot partition of the sd card (not the /boot folder in the root partition). This is well documented other places.

Static ip

Open /etc/dhcpcd.conf on the pi's SD-card, and uncomment the example for a static ip (starts around line 40). Set the addresses to

# Example static IP configuration:
interface eth0
static ip_address=10.42.0.182/24
static routers=10.42.0.1
static domain_name_servers=10.42.0.1 8.8.8.8 fd51:42f8:caae:d92e::1

Setting up your laptop

First, make sure you have networkmanager (with GUI) installed on your laptop. Then, make sure dnsmasq is not running as a service:
systemctl status dnsmasq
If this command prints that the service is stopped, then you're good.

Next we have to config networkmanager. Open /etc/NetworkManager/NetworkManager.conf and add the following two lines at the top:

[main]
DNS=dnsmasq

Then reboot. This step might not be necessary. It might be sufficient to restart the NetworkManager service. Now go to the NetworkManager GUI (usually accessed by an icon in the corner of the screen) and choose Edit Connections... In the window that pops up, click the + icon to create a new connection. Choose Ethernet as the type and press Create.... Go to the IPv4 Settings tab and select the method Shared to other computers. Give the connection a good name and save.

Connect the Raspberry Pi and make sure your laptop is using your new connection as its ethernet connection. If it is, your pi should now have an ip given to it by your pc. You can find this by first running ifconfig. This should give you several blocks of text, one for each network interface. You're interested in the one that is something like enp0s25 or eth0. It should have a line that reads something similar to
inet 10.42.0.1 netmask 255.255.255.0 broadcast 10.42.0.255
look at the broadcast address (in this case 10.42.0.255). If it is different than mine, power off the pi and put the SD card back in your laptop to change the static ip_address to something where the first three numbers are the same as in your broadcast address. Also change the static routers and the first of the domain_name_servers to your laptop's inet address. Power the pi back on and connect it. Run ifconfig again to see that the addresses have not changed.

ssh into the pi

ssh [email protected]
If you get connection refused, the pi isn't running an ssh server. If you get host unreachable, I'm sorry.

Hope this helps someone!

This was a developer mistake - a misplaced ending brace, which made the above function a nested function.

I see a lot of questions related to the undefined function error in SO. Let me note down this as an answer, in case someone else have the same issue with function scope.

Things I tried to troubleshoot first:

1. Searched for the php file with the function definition in it. Verified that the file exists.
2. Verified that the require (or include) statement for the above file exists in the page. Also, verified the absolute path in the require/include is correct.
3. Verified that the filename is spelled correctly in the require statement.
4. Echoed a word in the included file, to see if it has been properly included.
5. Defined a separate function at the end of file, and called it. It worked too.

It was difficult to trace the braces, since the functions were very long - problem with legacy systems. Further steps to troubleshoot were this:

1. I already defined a simple print function at the end of included file. I moved it to just above the "undefined function". That made it undefined too.

2. Identified this as some scope issue.

3. Used the Netbeans collapse (code fold) feature to check the function just above this one. So, the 1000 lines function above just collapsed along with this one, making this a nested function.

4. Once the problem identified, cut-pasted the function to the end of file, which solved the issue.

For my case, below worked on Mac:

I could not access container IPs directly on Mac. I need to use localhost with port forwarding, e.g. if the port is 8000, then http://localhost:8000

The original answer was from: https://github.com/docker/for-mac/issues/2670#issuecomment-371249949

One possible solution that I use is to use python3. It seems to solve many utf issues.

Sorry for the late answer, but it may help people in the future.

For example,

#!/usr/bin/env python3
import json
# your code follows

I had a similar issue; turns out it was case-sensitivity issue. So, make sure you use the proper case.

This answer predates version 1.1.5 where a proper ternary in the $parse function wasn't available. Use this answer if you're on a lower version, or as an example of filters:

angular.module('myApp.filters', [])
  
  .filter('conditional', function() {
    return function(condition, ifTrue, ifFalse) {
      return condition ? ifTrue : ifFalse;
    };
  });

And then use it as

<i ng-class="checked | conditional:'icon-check':'icon-check-empty'"></i>

Java Language Specification says that

Program Exit

A program terminates all its activity and exits when one of two things happens:

All the threads that are not daemon threads terminate.

Some thread invokes the exit method of class Runtime or class System, and the exit operation is not forbidden by the security manager.

It means that You should use it when You have big program (well, at lest bigger than this one) and want to finish its execution.

I used the property

display: table;

and

display: table-cell;

to achieve the same.Link to fiddle below shows 3 tables wrapped in divs and these divs are further wrapped in a parent div

<div id='content'>
   <div id='div-1'><!-- COntains table --></div>
   <div id='div-2'><!-- contains two more divs that require to be arranged one below other --></div>
</div>

Here is the jsfiddle: http://jsfiddle.net/vikikamath/QU6WP/1/ I thought this might be helpful to someone looking to set divs in same line without using display-inline

Thanks to the references shared here and elsewhere, I've made an online script / tool that one can use to obtain all videos of a channel.

It combines API calls to youtube.channels.list, playlistItems, videos. It uses recursive functions to make the asynchronous callbacks run the next iteration upon getting a valid response.

This also serves to limit the actual number of requests made at a time, hence keeping you safe from violating YouTube API rules. Sharing shortened snippets and then a link to the full code. I got around the 50 max results per call limitation by using the nextPageToken value that comes in the response to fetch the next 50 results and so on.

function getVideos(nextPageToken, vidsDone, params) {
    $.getJSON("https://www.googleapis.com/youtube/v3/playlistItems", {
        key: params.accessKey,
        part: "snippet",
        maxResults: 50,
        playlistId: params.playlistId,
        fields: "items(snippet(publishedAt, resourceId/videoId, title)), nextPageToken",
        pageToken: ( nextPageToken || '')
        },
        function(data) {
            // commands to process JSON variable, extract the 50 videos info

            if ( vidsDone < params.vidslimit) {

                // Recursive: the function is calling itself if
                // all videos haven't been loaded yet
                getVideos( data.nextPageToken, vidsDone, params);

            }
             else {
                 // Closing actions to do once we have listed the videos needed.
             }
    });
}

This got a basic listing of the videos, including id, title, date of publishing and similar. But to get more detail of each video like view counts and likes, one has to make API calls to videos.

// Looping through an array of video id's
function fetchViddetails(i) {
    $.getJSON("https://www.googleapis.com/youtube/v3/videos", {
        key: document.getElementById("accesskey").value,
        part: "snippet,statistics",
        id: vidsList[i]
        }, function(data) {

            // Commands to process JSON variable, extract the video
            // information and push it to a global array
            if (i < vidsList.length - 1) {
                fetchViddetails(i+1) // Recursive: calls itself if the
                                     //            list isn't over.
            }
});

See the full code here, and live version here. (Edit: fixed github link)
Edit: Dependencies: JQuery, Papa.parse

It is very inefficient to store all values in memory, so the objects are reused and loaded one at a time. See this other SO question for a good explanation. Summary:

[...] when looping through the Iterable value list, each Object instance is re-used, so it only keeps one instance around at a given time.

I found a posting about Using the Windows Hosts File that also says "No wildcards are allowed."

In the past, I have just added the additional entries to the hosts file, because (as previously said), it's not that much extra work when you already are editing the apache config file.

Assuming that your Sheet1 is not necessary active you would need to use this improved code of yours:

i = ActiveWorkbook.Worksheets("Sheet1").Range("A2" , Worksheets("Sheet1").Range("A2").End(xlDown)).Rows.Count

Look into full worksheet reference for second argument for Range(arg1, arg2) which important in this situation.

Your task declaration is incorrectly combining the Copy task type and project.copy method, resulting in a task that has nothing to copy and thus never runs. Besides, Copy isn't the right choice for renaming a directory. There is no Gradle API for renaming, but a bit of Groovy code (leveraging Java's File API) will do. Assuming Project1 is the project directory:

task renABCToXYZ {     doLast {         file("ABC").renameTo(file("XYZ"))     } } 

Looking at the bigger picture, it's probably better to add the renaming logic (i.e. the doLast task action) to the task that produces ABC.

behaves as an inline-block element as it allows other images in same line i.e. inline and also we can change the width and height of the image and this is the property of a block element. Hence, provide both the features of inline and block elements.

You can use str.translate():

s.translate(None, ",!.;")

Example:

>>> s = "asjo,fdjk;djaso,oio!kod.kjods;dkps"
>>> s.translate(None, ",!.;")
'asjofdjkdjasooiokodkjodsdkps'
