context is where this refers to in your iterator function. For example:

var person = {};
person.friends = {
  name1: true,
  name2: false,
  name3: true,
  name4: true
};

_.each(['name4', 'name2'], function(name){
  // this refers to the friends property of the person object
  alert(this[name]);
}, person.friends);

When you include Underscore, it attaches itself to the window object, and so is available globally.

So you can use it from Angular code as-is.

You can also wrap it up in a service or a factory, if you'd like it to be injected:

var underscore = angular.module('underscore', []);
underscore.factory('_', ['$window', function($window) {
  return $window._; // assumes underscore has already been loaded on the page
}]);

And then you can ask for the _ in your app's module:

// Declare it as a dependency of your module
var app = angular.module('app', ['underscore']);

// And then inject it where you need it
app.controller('Ctrl', function($scope, _) {
  // do stuff
});

It's also good to note that an each loop cannot be broken out of — to break, use _.find instead.

http://underscorejs.org/#each

well, this using lodash or vanilla javascript it depends on the situation.

but for just return the array that contains the duplicates it can be achieved by the following, offcourse it was taken from @1983

var result = result1.filter(function (o1) {
    return result2.some(function (o2) {
        return o1.id === o2.id; // return the ones with equal id
   });
});
// if you want to be more clever...
let result = result1.filter(o1 => result2.some(o2 => o1.id === o2.id));

How about this version in plain JS (ES6 / ES2015)?

let newObj = Object.assign(...Object.keys(obj).map(k => ({[k]: obj[k] * 3})));

jsbin

If you want to map over an object recursively (map nested obj), it can be done like this:

const mapObjRecursive = (obj) => {
  Object.keys(obj).forEach(key => {
    if (typeof obj[key] === 'object') obj[key] = mapObjRecursive(obj[key]);
    else obj[key] = obj[key] * 3;
  });
  return obj;
};

jsbin

Since ES7 / ES2016 you can use Object.entries instead of Object.keys like this:

let newObj = Object.assign(...Object.entries(obj).map([k, v] => ({[k]: v * 3})));

Or :

    var _ = require('underscore')._;

This should do the trick:

<% if (typeof(date) !== "undefined") { %>
    <span class="date"><%= date %></span>
<% } %>

Remember that in underscore.js templates if and for are just standard javascript syntax wrapped in <% %> tags.

When available, I believe that most lodash array functions will show the iteration. But sorting isn't really an iteration in the same way: when you're on the number 66, you aren't processing the fourth item in the array until it's finished. A custom sort function will loop through an array a number of times, nudging adjacent numbers forward or backward, until the everything is in its proper place.

If you can't use Underscorejs, you can implement it yourself. By attaching new methods to the Number and String prototypes, you could do it like this (using ES6 arrow functions):

// With String
"5".times( (i) => console.log("number "+i) );

// With number variable
var five = 5;
five.times( (i) => console.log("number "+i) );

// With number literal (parentheses required)
(5).times( (i) => console.log("number "+i) );

You simply have to create a function expression (of whatever name) and assign it to whatever property name (on the prototypes) you would like to access it as:

var timesFunction = function(callback) {
  if (typeof callback !== "function" ) {
    throw new TypeError("Callback is not a function");
  } else if( isNaN(parseInt(Number(this.valueOf()))) ) {
    throw new TypeError("Object is not a valid number");
  }
  for (var i = 0; i < Number(this.valueOf()); i++) {
    callback(i);
  }
};

String.prototype.times = timesFunction;
Number.prototype.times = timesFunction;

@Iulian Pinzaru's answer was almost exactly what I needed, but it doesn't work if your objects have any null values. This version fixes that.

function  deepSearch (object, key, predicate) {
  if (object.hasOwnProperty(key) && predicate(key, object[key]) === true) return object

  for (let i = 0; i < Object.keys(object).length; i++) {
    const nextObject = object[Object.keys(object)[i]];
    if (nextObject && typeof nextObject === "object") {
      let o = deepSearch(nextObject, key, predicate)
      if (o != null) return o
    }
  }
  return null
}

Descending order using underscore can be done by multiplying the return value by -1.

//Ascending Order:
_.sortBy([2, 3, 1], function(num){
    return num;
}); // [1, 2, 3]


//Descending Order:
_.sortBy([2, 3, 1], function(num){
    return num * -1;
}); // [3, 2, 1]

If you're sorting by strings not numbers, you can use the charCodeAt() method to get the unicode value.

//Descending Order Strings:
_.sortBy(['a', 'b', 'c'], function(s){ 
    return s.charCodeAt() * -1;
});

To add to Box9's answer:

Backbone.js is dependent on underscore.js, which itself implements John Resig's original microtemplates.

If you decide to use Backbone.js with Rails, be sure to check out the Jammit gem. It provides a very clean way to manage asset packaging for templates. http://documentcloud.github.com/jammit/#jst

By default Jammit also uses JResig's microtemplates, but it also allows you to replace the templating engine.

They are pretty similar, with Lodash is taking over...

They both are a utility library which takes the world of utility in JavaScript...

It seems Lodash is getting updated more regularly now, so more used in the latest projects...

Also Lodash seems is lighter by a couple of KBs...

Both have a good API and documentation, but I think the Lodash one is better...

Here is a screenshot for each of the documentation items for getting the first value of an array...

Underscore.js:

Lodash:

As things may get updated time to time, just check their website also...

Lodash

Underscore.js

Use:

var config = {};
jQuery(form).serializeArray().map(function(item) {
    if ( config[item.name] ) {
        if ( typeof(config[item.name]) === "string" ) {
            config[item.name] = [config[item.name]];
        }
        config[item.name].push(item.value);
    } else {
        config[item.name] = item.value;
    }
});

I wanted to share one more important finding.

use of <%= variable => would result in cross-site scripting vulnerability. So its more safe to use <%- variable -> instead.

We had to replace <%= with <%- to prevent cross-site scripting attacks. Not sure, whether this will it have any impact on the performance

My way is importing the jquery library.

<script
  src="https://code.jquery.com/jquery-3.3.1.js"
  integrity="sha256-2Kok7MbOyxpgUVvAk/HJ2jigOSYS2auK4Pfzbm7uH60="
  crossorigin="anonymous"></script>

or use map

Results.map(obj=> ({ ...obj, Active: 'false' }))

Edited to reflect comment by @adrianolsk to not mutate the original and instead return a new object for each.

Read the spec

Isn't it this simple?

var result = _(data)
            .groupBy(x => x.color)
            .map((value, key) => ({color: key, users: value}))
            .value();

here's my solution (coffeescript) :

_.mixin
  deepUniq: (coll) ->
    result = []
    remove_first_el_duplicates = (coll2) ->

      rest = _.rest(coll2)
      first = _.first(coll2)
      result.push first
      equalsFirst = (el) -> _.isEqual(el,first)

      newColl = _.reject rest, equalsFirst

      unless _.isEmpty newColl
        remove_first_el_duplicates newColl

    remove_first_el_duplicates(coll)
    result

example:

_.deepUniq([ {a:1,b:12}, [ 2, 1, 2, 1 ], [ 1, 2, 1, 2 ],[ 2, 1, 2, 1 ], {a:1,b:12} ]) 
//=> [ { a: 1, b: 12 }, [ 2, 1, 2, 1 ], [ 1, 2, 1, 2 ] ]

Usually I use Lodash JavaScript utility library with a pre-built groupBy() method. It is pretty easy to use, see more details here.

findIndex was added in 1.8:

index = _.findIndex(tv, function(voteItem) { return voteItem.id == voteID })

See: http://underscorejs.org/#findIndex

Alternatively, this also works, if you don't mind making another temporary list:

index = _.indexOf(_.pluck(tv, 'id'), voteId);

See: http://underscorejs.org/#pluck

Thanks to Gruff Bunny and Louis' comments, I found the source of the issue.

As I use Backbone.js too, I loaded a special build of Lodash compatible with Backbone and Underscore that disables some features. In this example:

var clone = _.clone(data, true);

data[1].values.d = 'x';

• with the Normal build: _.isEqual(data, clone) === false
• with the Underscore build: _.isEqual(data, clone) === true

I just replaced the Underscore build with the Normal build in my Backbone application and the application is still working. So I can now use the Lodash .clone with the expected behaviour.

Edit 2018: the Underscore build doesn't seem to exist anymore. If you are reading this in 2018, you could be interested by this documentation (Backbone and Lodash).

Underscore has a _without() method perfect for removing an item from an array, especially if you have the object to remove.

Returns a copy of the array with all instances of the values removed.

_.without(["bob", "sam", "fred"], "sam");

=> ["bob", "fred"]

Works with more complex objects too.

var bob = { Name: "Bob", Age: 35 };
var sam = { Name: "Sam", Age: 19 };
var fred = { Name: "Fred", Age: 50 };

var people = [bob, sam, fred]

_.without(people, sam);

=> [{ Name: "Bob", Age: 35 }, { Name: "Fred", Age: 50 }];

If you don't have the item to remove, just a property of it, you can use _.findWhere and then _.without.

You can use lodash, download here (4.17.15)

Example code:

var object = [{ 'x': 1, 'y': 2 }, { 'x': 2, 'y': 1 }, { 'x': 1, 'y': 2 }];

_.uniqWith(object, _.isEqual);

// => [{ 'x': 1, 'y': 2 }, { 'x': 2, 'y': 1 }]

You have a couple of questions here, so I'll address them separately:

I need to store a number of selected items in one field in a database

My general rule is: don't. This is something which all but requires a second table (or third) with a foreign key. Sure, it may seem easier now, but what if the use case comes along where you need to actually query for those items individually? It also means that you have more options for lazy instantiation and you have a more consistent experience across multiple frameworks/languages. Further, you are less likely to have connection timeout issues (30,000 characters is a lot).

You mentioned that you were thinking about using ENUM. Are these values fixed? Do you know them ahead of time? If so this would be my structure:

Base table (what you have now):

| id primary_key sequence
| -- other columns here.

Items table:

| id primary_key sequence
| descript VARCHAR(30) UNIQUE

Map table:

| base_id  bigint
| items_id bigint

Map table would have foreign keys so base_id maps to Base table, and items_id would map to the items table.

And if you'd like an easy way to retrieve this from a DB, then create a view which does the joins. You can even create insert and update rules so that you're practically only dealing with one table.

What format should I use store the data?

If you have to do something like this, why not just use a character delineated string? It will take less processing power than a CSV, XML, or JSON, and it will be shorter.

What column type should I use store the data?

Personally, I would use TEXT. It does not sound like you'd gain much by making this a BLOB, and TEXT, in my experience, is easier to read if you're using some form of IDE.

info = [];
info[0] = 'hi';
info[1] = 'hello';


$.ajax({
   type: "POST",
   data: {info:info},
   url: "index.php",
   success: function(msg){
     $('.answer').html(msg);
   }
});

I faced with the problem like this.

The problem was that I added the public key without '-----BEGIN PUBLIC KEY-----' at the beginning and without '-----END PUBLIC KEY-----'.

So it causes the error.

Initially, my public key was like this:

-----BEGIN PUBLIC KEY-----
WnsbGUXbb0GbJSCwCBAhrzT0s2KMRyqqS7QBiIG7t3H2Qtmde6UoUIcTTPJgv71
......
oNLcaK2wKKyRdcROK7ZTSCSMsJpAFOY
-----END PUBLIC KEY-----

But I used just this part:

WnsbGUXb+b0GbJSCwCBAhrzT0s2KMRyqqS7QBiIG7t3H2Qtmde6UoUIcTTPJgv71
......
oNLcaK2w+KKyRdcROK7ZTSCSMsJpAFOY

Using the COUNT aggregate, you can first count how many rows there are and store in a variable called @cnt. Then you can compute parameters for the OFFSET-FETCH filter to specify, based on qty ordering, how many rows to skip (offset value) and how many to filter (fetch value).

The number of rows to skip is (@cnt - 1) / 2. It’s clear that for an odd count this calculation is correct because you first subtract 1 for the single middle value, before you divide by 2.

This also works correctly for an even count because the division used in the expression is integer division; so, when subtracting 1 from an even count, you’re left with an odd value.

When dividing that odd value by 2, the fraction part of the result (.5) is truncated. The number of rows to fetch is 2 - (@cnt % 2). The idea is that when the count is odd the result of the modulo operation is 1, and you need to fetch 1 row. When the count is even the result of the modulo operation is 0, and you need to fetch 2 rows. By subtracting the 1 or 0 result of the modulo operation from 2, you get the desired 1 or 2, respectively. Finally, to compute the median quantity, take the one or two result quantities, and apply an average after converting the input integer value to a numeric one as follows:

DECLARE @cnt AS INT = (SELECT COUNT(*) FROM [Sales].[production].[stocks]);
SELECT AVG(1.0 * quantity) AS median
FROM ( SELECT quantity
FROM [Sales].[production].[stocks]
ORDER BY quantity
OFFSET (@cnt - 1) / 2 ROWS FETCH NEXT 2 - @cnt % 2 ROWS ONLY ) AS D;

var option = driver.FindElement(By.Id("employmentType"));
        var selectElement = new SelectElement(option);
        Task.Delay(3000).Wait();
        selectElement.SelectByIndex(2);
        Console.Read();

use following LoadType method to use System.Reflection to load all registered(GAC) and referenced assemblies and check for typeName

public Type[] LoadType(string typeName)
{
    return LoadType(typeName, true);
}

public Type[] LoadType(string typeName, bool referenced)
{
    return LoadType(typeName, referenced, true);
}

private Type[] LoadType(string typeName, bool referenced, bool gac)
{
    //check for problematic work
    if (string.IsNullOrEmpty(typeName) || !referenced && !gac)
        return new Type[] { };

    Assembly currentAssembly = Assembly.GetExecutingAssembly();

    List<string> assemblyFullnames = new List<string>();
    List<Type> types = new List<Type>();

    if (referenced)
    {            //Check refrenced assemblies
        foreach (AssemblyName assemblyName in currentAssembly.GetReferencedAssemblies())
        {
            //Load method resolve refrenced loaded assembly
            Assembly assembly = Assembly.Load(assemblyName.FullName);

            //Check if type is exists in assembly
            var type = assembly.GetType(typeName, false, true);

                if (type != null && !assemblyFullnames.Contains(assembly.FullName))
                {

You may need to go to Window -> Android SDK Manager -> Packages -> Reload to fetch latest updates and then update the SDK.

To read a specific set of columns from a dataset you, there are several other options:

1) With freadfrom the data.table-package:

You can specify the desired columns with the select parameter from fread from the data.table package. You can specify the columns with a vector of column names or column numbers.

For the example dataset:

library(data.table)
dat <- fread("data.txt", select = c("Year","Jan","Feb","Mar","Apr","May","Jun"))
dat <- fread("data.txt", select = c(1:7))

Alternatively, you can use the drop parameter to indicate which columns should not be read:

dat <- fread("data.txt", drop = c("Jul","Aug","Sep","Oct","Nov","Dec"))
dat <- fread("data.txt", drop = c(8:13))

All result in:

> data
  Year Jan Feb Mar Apr May Jun
1 2009 -41 -27 -25 -31 -31 -39
2 2010 -41 -27 -25 -31 -31 -39
3 2011 -21 -27  -2  -6 -10 -32

UPDATE: When you don't want fread to return a data.table, use the data.table = FALSE-parameter, e.g.: fread("data.txt", select = c(1:7), data.table = FALSE)

2) With read.csv.sql from the sqldf-package:

Another alternative is the read.csv.sql function from the sqldf package:

library(sqldf)
dat <- read.csv.sql("data.txt",
                    sql = "select Year,Jan,Feb,Mar,Apr,May,Jun from file",
                    sep = "\t")

3) With the read_*-functions from the readr-package:

library(readr)
dat <- read_table("data.txt",
                  col_types = cols_only(Year = 'i', Jan = 'i', Feb = 'i', Mar = 'i',
                                        Apr = 'i', May = 'i', Jun = 'i'))
dat <- read_table("data.txt",
                  col_types = list(Jul = col_skip(), Aug = col_skip(), Sep = col_skip(),
                                   Oct = col_skip(), Nov = col_skip(), Dec = col_skip()))
dat <- read_table("data.txt", col_types = 'iiiiiii______')

From the documentation an explanation for the used characters with col_types:

each character represents one column: c = character, i = integer, n = number, d = double, l = logical, D = date, T = date time, t = time, ? = guess, or _/- to skip the column

You should learn the raise statement of python for that. It should be kept inside the try block. Example -

try:
    raise TypeError            #remove TypeError by any other error if you want
except TypeError:
    print('TypeError raised')

The simplest technique is to use NSString *uuid = [[NSProcessInfo processInfo] globallyUniqueString]. See the NSProcessInfo class reference.

A few comments:

• The Nyquist frequency is half the sampling rate.
• You are working with regularly sampled data, so you want a digital filter, not an analog filter. This means you should not use analog=True in the call to butter, and you should use scipy.signal.freqz (not freqs) to generate the frequency response.
• One goal of those short utility functions is to allow you to leave all your frequencies expressed in Hz. You shouldn't have to convert to rad/sec. As long as you express your frequencies with consistent units, the scaling in the utility functions takes care of the normalization for you.

Here's my modified version of your script, followed by the plot that it generates.

    return b, a

def butter_lowpass_filter(data, cutoff, fs, order=5):
    b, a = butter_lowpass(cutoff, fs, order=order)
    y = lfilter(b, a, data)
    return y


# Filter requirements.
order = 6
fs = 30.0       # sample rate, Hz
cutoff = 3.667  # desired cutoff frequency of the filter, Hz

# Get the filter coefficients so we can check its frequency response.
b, a = butter_lowpass(cutoff, fs, order)

# Plot the frequency response.
w, h = freqz(b, a, worN=8000)
plt.subplot(2, 1, 1)
plt.plot(0.5*fs*w/np.pi, np.abs(h), 'b')
plt.plot(cutoff, 0.5*np.sqrt(2), 'ko')
plt.axvline(cutoff, color='k')
plt.xlim(0, 0.5*fs)
plt.title("Lowpass Filter Frequency Response")
plt.xlabel('Frequency [Hz]')
plt.grid()


# Demonstrate the use of the filter.
# First make some data to be filtered.
T = 5.0         # seconds
n = int(T * fs) # total number of samples
t = np.linspace(0, T, n, endpoint=False)
# "Noisy" data.  We want to recover the 1.2 Hz signal from this.
data = np.sin(1.2*2*np.pi*t) + 1.5*np.cos(9*2*np.pi*t) + 0.5*np.sin(12.0*2*np.pi*t)

# Filter the data, and plot both the original and filtered signals.
y = butter_lowpass_filter(data, cutoff, fs, order)

plt.subplot(2, 1, 2)
plt.plot(t, data, 'b-', label='data')
plt.plot(t, y, 'g-', linewidth=2, label='filtered data')
plt.xlabel('Time [sec]')
plt.grid()
plt.legend()

plt.subplots_adjust(hspace=0.35)

In my case with Xamarin Forms 4.7 and Visual Studio 2019 16.7.0 Preview 3.1, the problem was version mismatch of lately updated Android Build tools (apksigner) and JDK. Updated JDK to latest and pointed the new JDK path on Tools->Options->Xamarin->Android Settings, and it works.

To find first element in a sequence seq that matches a predicate:

next(x for x in seq if predicate(x))

Or _{(itertools.ifilter on Python 2)}:

next(filter(predicate, seq))

It raises StopIteration if there is none.

To return None if there is no such element:

next((x for x in seq if predicate(x)), None)

Or:

next(filter(predicate, seq), None)

m <- matrix(1:20, ncol = 4) 
colnames(m) <- letters[1:4]

The following command will select the first row of the matrix above.

subset(m, m[,4] == 16)

And this will select the last three.

subset(m, m[,4] > 17)

The result will be a matrix in both cases. If you want to use column names to select columns then you would be best off converting it to a dataframe with

mf <- data.frame(m)

Then you can select with

mf[ mf$a == 16, ]

Or, you could use the subset command.

I did this:

import re

def requirements(filename):
    with open(filename) as f:
        ll = f.read().splitlines()
    d = {}
    for l in ll:
        k, v = re.split(r'==|>=', l)
        d[k] = v
    return d

def packageInfo():
    try:
        from pip._internal.operations import freeze
    except ImportError:
        from pip.operations import freeze

    d = {}
    for kv in freeze.freeze():
        k, v = re.split(r'==|>=', kv)
        d[k] = v
    return d

req = getpackver('requirements.txt')
pkginfo = packageInfo()

for k, v in req.items():
    print(f'{k:<16}: {v:<6} -> {pkginfo[k]}')

You can use scipy for p-value. This code is from scipy documentation.

>>> from scipy import stats
>>> import numpy as np
>>> x = np.random.random(10)
>>> y = np.random.random(10)
>>> slope, intercept, r_value, p_value, std_err = stats.linregress(x,y)

The problem is that you are passing a nullable type to a non-nullable type.

You can do any of the following solution:

A. Declare your dt as nullable

DateTime? dt = dateTime;

B. Use Value property of the the DateTime? datetime

DateTime dt = datetime.Value;

C. Cast it

DateTime dt = (DateTime) datetime;

Font myFont = new Font ("Courier New", 1, 17);

The 17 represents the font size. Once you have that, you can put:

g.setFont (myFont);
g.drawString ("Hello World", 10, 10);

Your test is good, but it measures only some specific situation: we have one polygon with many vertices, and long array of points to check them within polygon.

Moreover, I suppose that you're measuring not matplotlib-inside-polygon-method vs ray-method, but matplotlib-somehow-optimized-iteration vs simple-list-iteration

Let's make N independent comparisons (N pairs of point and polygon)?

# ... your code...
lenpoly = 100
polygon = [[np.sin(x)+0.5,np.cos(x)+0.5] for x in np.linspace(0,2*np.pi,lenpoly)[:-1]]

M = 10000
start_time = time()
# Ray tracing
for i in range(M):
    x,y = np.random.random(), np.random.random()
    inside1 = ray_tracing_method(x,y, polygon)
print "Ray Tracing Elapsed time: " + str(time()-start_time)

# Matplotlib mplPath
start_time = time()
for i in range(M):
    x,y = np.random.random(), np.random.random()
    inside2 = path.contains_points([[x,y]])
print "Matplotlib contains_points Elapsed time: " + str(time()-start_time)

Result:

Ray Tracing Elapsed time: 0.548588991165
Matplotlib contains_points Elapsed time: 0.103765010834

Matplotlib is still much better, but not 100 times better. Now let's try much simpler polygon...

lenpoly = 5
# ... same code

result:

Ray Tracing Elapsed time: 0.0727779865265
Matplotlib contains_points Elapsed time: 0.105288982391

What about:

If Not I = x Then

  ' Do something '

End If

' Move to next item '

For some time now I've been thinking about near-compile-time constraints, so this is a perfect opportunity to launch the concept.

The basic idea is that if you cannot do a check compile time, you should do it at the earliest possible point in time, which is basically the moment the application starts. If all checks are okay, the application will run; if a check fails, the application will fail instantly.

Behavior

The best possible outcome is that our program doesn't compile if the constraints are not met. Unfortunately that's not possible in the current C# implementation.

Next best thing is that the program crashes the moment it's started.

The last option is that the program will crash the moment the code is hit. This is the default behavior of .NET. For me, this is completely unacceptable.

Prerequirements

We need to have a constraint mechanism, so for the lack of anything better... let's use an attribute. The attribute will be present on top of a generic constraint to check if it matches our conditions. If it doesn't, we give an ugly error.

This enables us to do things like this in our code:

public class Clas<[IsInterface] T> where T : class

(I've kept the where T:class here, because I always prefer compile-time checks to run-time checks)

So, that only leaves us with 1 problem, which is checking if all the types that we use match the constraint. How hard can it be?

Let's break it up

Generic types are always either on a class (/struct/interface) or on a method.

Triggering a constraint requires you to do one of the following things:

1. Compile-time, when using a type in a type (inheritance, generic constraint, class member)
2. Compile-time, when using a type in a method body
3. Run-time, when using reflection to construct something based on the generic base class.
4. Run-time, when using reflection to construct something based on RTTI.

At this point, I would like to state that you should always avoid doing (4) in any program IMO. Regardless, these checks won't support it, since it would effectively mean solving the halting problem.

Case 1: using a type

Example:

public class TestClass : SomeClass<IMyInterface> { ... } 

Example 2:

public class TestClass 
{ 
    SomeClass<IMyInterface> myMember; // or a property, method, etc.
} 

Basically this involves scanning all types, inheritance, members, parameters, etc, etc, etc. If a type is a generic type and has a constraint, we check the constraint; if it's an array, we check the element type.

At this point I must add that this will break the fact that by default .NET loads types 'lazy'. By scanning all the types, we force the .NET runtime to load them all. For most programs this shouldn't be a problem; still, if you use static initializers in your code, you might encounter problems with this approach... That said, I wouldn't advice anyone to do this anyways (except for things like this :-), so it shouldn't give you a lot of problems.

Case 2: using a type in a method

Example:

void Test() {
    new SomeClass<ISomeInterface>();
}

To check this we have only 1 option: decompile the class, check all member tokens that are used and if one of them is the generic type - check the arguments.

Case 3: Reflection, runtime generic construction

Example:

typeof(CtorTest<>).MakeGenericType(typeof(IMyInterface))

I suppose it's theoretically possible to check this with similar tricks as case (2), but the implementation of it is much harder (you need to check if MakeGenericType is called in some code path). I won't go into details here...

Case 4: Reflection, runtime RTTI

Example:

Type t = Type.GetType("CtorTest`1[IMyInterface]");

This is the worst case scenario and as I explained before generally a bad idea IMHO. Either way, there's no practical way to figure this out using checks.

Testing the lot

Creating a program that tests case (1) and (2) will result in something like this:

[AttributeUsage(AttributeTargets.GenericParameter)]
public class IsInterface : ConstraintAttribute
{
    public override bool Check(Type genericType)
    {
        return genericType.IsInterface;
    }

    public override string ToString()
    {
        return "Generic type is not an interface";
    }
}

public abstract class ConstraintAttribute : Attribute
{
    public ConstraintAttribute() {}

    public abstract bool Check(Type generic);
}

Using the code

Well, that's the easy part :-)

// Create something illegal
public class Bar2 : IMyInterface
{
    public void Execute()
    {
        throw new NotImplementedException();
    }
}

// Our fancy check
public class Foo<[IsInterface] T>
{
}

class Program
{
    static Program()
    {
        // Perform all runtime checks
        new NCTChecks(typeof(Program));
    }

    static void Main(string[] args)
    {
        // Normal operation
        Console.WriteLine("Foo");
        Console.ReadLine();
    }
}

Some code examples for simple GET request. Maybe this helps understanding the difference. Using then:

$http.get('/someURL').then(function(response) {
    var data = response.data,
        status = response.status,
        header = response.header,
        config = response.config;
    // success handler
}, function(response) {
    var data = response.data,
        status = response.status,
        header = response.header,
        config = response.config;
    // error handler
});

Using success/error:

$http.get('/someURL').success(function(data, status, header, config) {
    // success handler
}).error(function(data, status, header, config) {
    // error handler
});

Here's a funny answer.

You can declare a final one-element array and change the elements of the array all you want apparently. I'm sure it breaks the very reason why this compiler rule was implemented in the first place but it's handy when you're in a time-bind as I was today.

I actually can't claim credit for this one. It was IntelliJ's recommendation! Feels a bit hacky. But doesn't seem as bad as a global variable so I thought it worth mentioning here. It's just one solution to the problem. Not necessarily the best one.

final int[] tapCount = {0};

addSiteButton.setOnClickListener(new View.OnClickListener() {

    @Override
    public void onClick(View v) {
       tapCount[0]++;
    }

});

This error coud be also due to your google account already having Google Wallet/Google Checkout account linked. The existing account cannot be used for example it is a merchant account. Took me 20 minutes to figure out. Add new Google Account to your device, restart. While in Google Play switch to your new account. Buy your app/book/movie.

ESLint defaults to ES5 syntax-checking. You'll want to override to the latest well-supported version of JavaScript.

Try adding a .eslintrc file to your project. Inside it:

{
    "parserOptions": {
        "ecmaVersion": 2017
    },

    "env": {
        "es6": true
    }
}

Hopefully this helps.

EDIT: I also found this example .eslintrc which might help.

You could use querySelector() with attribute selector '[attribute="value"]', then affect css rule using .style, as you can see in the example below:

document.querySelector('a[aria-expanded="true"]').style.backgroundColor = "#42DCA3";

<ul><li class="active">_x000D_
  <a href="#3a" class="btn btn-default btn-lg" data-toggle="tab" aria-expanded="true"> <span class="network-name">Google+ with aria expanded true</span></a>_x000D_
  </li>_x000D_
  <li>_x000D_
    <a href="#3a" class="btn btn-default btn-lg" data-toggle="tab" aria-expanded="false"> <span class="network-name">Google+ with aria expanded false</span></a>_x000D_
  </li>_x000D_
</ul>

jQuery solution :

If you want to use a jQuery solution you could simply use css() method :

$('a[aria-expanded="true"]').css('background-color','#42DCA3');

Hope this helps.

It might be worth mentioning that the bisect docs now provide searching examples: http://docs.python.org/library/bisect.html#searching-sorted-lists

(Raising ValueError instead of returning -1 or None is more pythonic – list.index() does it, for example. But of course you can adapt the examples to your needs.)

This python3 example uses a recursive solution:

# Hanoi towers puzzle
# for each n, you have to move n-1 disks off the n disk onto another peg
# then you move the n disk to a free peg
# then you move the n-1 disks on the other peg back onto the n disk

def hanoi(n):
    if n == 1:
        return 1
    else:
        return hanoi(n-1) + 1 + hanoi(n-1)


for i in range(1, 11):
    print(f"n={i}, moves={hanoi(i)}")

Output:

n=1, moves=1
n=2, moves=3
n=3, moves=7
n=4, moves=15
n=5, moves=31
n=6, moves=63
n=7, moves=127
n=8, moves=255
n=9, moves=511
n=10, moves=1023

But of course the most efficient way to work out how many moves is to realise that the answers are always 1 less than 2^n. So the mathematical solution is 2^n - 1

Here's a solution that I've come up with. I paired up the LocationStrategy with the Router events. Using the LocationStrategy to set a boolean to know when a user's currently traversing through the browser history. This way, I don't have to store a bunch of URL and y-scroll data (which doesn't work well anyway, since each data is replaced based on URL). This also solves the edge case when a user decides to hold the back or forward button on a browser and goes back or forward multiple pages rather than just one.

P.S. I've only tested on the latest version of IE, Chrome, FireFox, Safari, and Opera (as of this post).

Hope this helps.

export class AppComponent implements OnInit {
  isPopState = false;

  constructor(private router: Router, private locStrat: LocationStrategy) { }

  ngOnInit(): void {
    this.locStrat.onPopState(() => {
      this.isPopState = true;
    });

    this.router.events.subscribe(event => {
      // Scroll to top if accessing a page, not via browser history stack
      if (event instanceof NavigationEnd && !this.isPopState) {
        window.scrollTo(0, 0);
        this.isPopState = false;
      }

      // Ensures that isPopState is reset
      if (event instanceof NavigationEnd) {
        this.isPopState = false;
      }
    });
  }
}

You could also do this in a single statement:

$j = "Somepath"
$files = Get-ChildItem -Path $j -Include '*.xlsx','*.zip' -Recurse -ErrorAction SilentlyContinue –File | ? {$_.Directory -notlike "$j\donotwantfoldername"}

Need Key & Value in Iteration

Use entrySet() to iterate through Map and need to access value and key:

Map<String, Person> hm = new HashMap<String, Person>();

hm.put("A", new Person("p1"));
hm.put("B", new Person("p2"));
hm.put("C", new Person("p3"));
hm.put("D", new Person("p4"));
hm.put("E", new Person("p5"));

Set<Map.Entry<String, Person>> set = hm.entrySet();

for (Map.Entry<String, Person> me : set) {
  System.out.println("Key :"+me.getKey() +" Name : "+ me.getValue().getName()+"Age :"+me.getValue().getAge());

}

Need Key in Iteration

If you want just to iterate over keys of map you can use keySet()

for(String key: map.keySet()) {
     Person value = map.get(key); 
}

Need Value in Iteration

If you just want to iterate over values of map you can use values()

for(Person person: map.values()) {

}

you cannot access array (php array) from js try

<?php
$array = array(1,2,3,4,5,6);
echo json_encode($array);
?>

and js

$(document).ready( function() {
    $('#prev').click(function() {
        $.ajax({
            type: 'POST',
            url: 'ajax.php',
            data: 'id=testdata',
            dataType: 'json',
            cache: false,
            success: function(result) {
                $('#content1').html(result[0]);
            },
        });
    });
});

the way I use jsonp like below:

function jsonp(uri) {
    return new Promise(function(resolve, reject) {
        var id = '_' + Math.round(10000 * Math.random());
        var callbackName = 'jsonp_callback_' + id;
        window[callbackName] = function(data) {
            delete window[callbackName];
            var ele = document.getElementById(id);
            ele.parentNode.removeChild(ele);
            resolve(data);
        }

        var src = uri + '&callback=' + callbackName;
        var script = document.createElement('script');
        script.src = src;
        script.id = id;
        script.addEventListener('error', reject);
        (document.getElementsByTagName('head')[0] || document.body || document.documentElement).appendChild(script)
    });
}

then use 'jsonp' method like this:

jsonp('http://xxx/cors').then(function(data){
    console.log(data);
});

This means that you must declare strict mode by writing "use strict" at the beginning of the file or the function to use block-scope declarations.

EX:

function test(){
    "use strict";
    let a = 1;
} 

As of Express 4.x

app.js

// above is all your node requires

// view engine setup
app.set('views', path.join(__dirname, 'views')); <-- ./views has all your .ejs files
app.set('view engine', 'ejs');

error.ejs

<!-- because ejs knows your root directory for views, you can navigate to the ./base directory and select the header.ejs file and include it -->

<% include ./base/header %> 
<h1> Other mark up here </h1>
<% include ./base/footer %>

The first parameter to LayoutParams is the width and the second is the height. So if you want the width to be FILL_PARENT, but the width to be, say, 20px, then use something new LayoutParams(FILL_PARENT, 20). Of course you should never use actual pixels in your code; you'll need to conver that to density-independent pixels, but you get the idea. Also, you need to make sure your parent LinearLayout has the right width and height that you're looking for. Seems to be you want the LinearLayout to fill the parent width-wise and then have the adview fill that linearlayout witdh-wise as well, so you probably need to specify android:layout_width:"fill_parent" and android:layout_height:"wrap_content" in your linear layout's xml.

You need rawQuery method.

Example:

private final String MY_QUERY = "SELECT * FROM table_a a INNER JOIN table_b b ON a.id=b.other_id WHERE b.property_id=?";

db.rawQuery(MY_QUERY, new String[]{String.valueOf(propertyId)});

Use ? bindings instead of putting values into raw sql query.

From .Net 3.5 you can use LINQ extension method that (sometimes) makes code flow a bit better.

Usage looks like this:

using System.Linq; 

// ...

public void My()
{
    var myArray = new[] { "abc", "123", "zyx" };
    List<string> myList = myArray.ToList();
}

PS. There's also ToArray() method that works in other way.

For working with DB Nulls, I created a bunch for my VB applications. I call them Cxxx2 as they are similar to VB's built-in Cxxx functions.

You can see them in my CLR Extensions project

http://www.codeplex.com/ClrExtensions/SourceControl/FileView.aspx?itemId=363867&changeSetId=17967

This trick here is using the esoteric table-layout:fixed rule

This CSS ought to work against your sample HTML:

table {table-layout:fixed}
td {overflow:hidden; white-space:nowrap}

You also ought to specify explicit column widths for the <td>s.

The table-layout:fixed rule says "The cell widths of this table depend on what I say, not on the actual content in the cells". This is useful normally because the browser can begin displaying the table after it has received the first <tr>. Otherwise, the browser has to receive the entire table before it can compute the column widths.

• Control F for search, or Control Shift F for global search
• Replace >< by >\n< with Regular Expressions enabled

It's worth noting that in Firefox 3 and Safari, resizing an image by just changing the height and width doesn't look too bad. In other browsers it can look very noisy because it's using nearest-neighbor resampling. Of course, you're paying to serve a larger image, but that might not matter.

My problem went away after I modified my Adapter implementation to use a copy of the items array instead of a reference. The setItems() method is called each time we have new items to show in the RecyclerView.

Instead of:

private class MyAdapter extends RecyclerView.Adapter<ItemHolder> {
     private List<MyItem> mItems;  

    (....)

    void setItems(List<MyItem> items) {
        mItems = items;
    }
}

I did:

void setItems(List<MyItem> items) {
    mItems = new ArrayList<>(items);
}

Just for reference, here is a benchmark of different technique rendering performances,

or

The -Wl,xxx option for gcc passes a comma-separated list of tokens as a space-separated list of arguments to the linker. So

gcc -Wl,aaa,bbb,ccc

eventually becomes a linker call

ld aaa bbb ccc

In your case, you want to say "ld -rpath .", so you pass this to gcc as -Wl,-rpath,. Alternatively, you can specify repeat instances of -Wl:

gcc -Wl,aaa -Wl,bbb -Wl,ccc

Note that there is no comma between aaa and the second -Wl.

Or, in your case, -Wl,-rpath -Wl,..

Just another example using HTML and CSS:

<div style="width: Auto; margin: 0 auto;">Hello</div>

Elaborating on previous answer by Pir Fahim, he's right but i'm using selectedItem.Text (only way to make it work to me)

Use the SelectedIndexChanged() event to store the data somewhere. In my case, i usually fill a custom class, something like:

class myItem {
    string name {get; set;}
    string price {get; set;}
    string desc {get; set;}
}

private void listBox1_SelectedIndexChanged(object sender, EventArgs e)
{
     myItem selected_item = new myItem();
     selected_item.name  = listBox1.SelectedItem.Text;
     Retrieve (selected_item.name);
}

And then you can retrieve the rest of data from a List of "myItems"..

myItem Retrieve (string wanted_item) {
    foreach (myItem item in my_items_list) {
        if (item.name == wanted_item) {
               // This is the selected item
               return item; 
        }
    }
    return null;
}

I was already using jquery. But I think its intuitive enough to just have:

var total_amount = 0; 
$.each(traveler, function( i, v ) { total_amount += v.Amount ; });

This is basically just a short-hand version of @akhouri's answer.

tl;dr

cp -R "/src/project 1/App" "/src/project 2"

Explanation:

Using quotes will cater for spaces in the directory names

cp -R "/src/project 1/App" "/src/project 2"

If the App directory is specified in the destination directory:

cp -R "/src/project 1/App" "/src/project 2/App"

and "/src/project 2/App" already exists the result will be "/src/project 2/App/App"

Best not to specify the directory copied in the destination so that the command can be repeated over and over with the expected result.

Inside a bash script:

cp -R "${1}/App" "${2}"

Alternatively, and this would give you more flexibility if testing for values other than 1 or 2 in future, is to use a switch statement

switch(value)
{
case 1:
case 2:
   return true;
default:
   return false
}

It's not clear what you want, or whether you want this trick to work with different targets, or whether you've defined these targets elsewhere, or what version of Make you're using, but what the heck, I'll go out on a limb:

ifeq (yes, ${TEST})
CXXFLAGS := ${CXXFLAGS} -DDESKTOP_TEST
test:
$(info ************  TEST VERSION ************)
else
release:
$(info ************ RELEASE VERSIOIN **********)
endif

Enclose the string in single quote it should work. Try this.

var jsonObj = '{"TeamList" : [{"teamid" : "1","teamname" : "Barcelona"}]}';
var obj = $.parseJSON(jsonObj);

Demo

If you want to execute that command, you should probably change:

PROCESS_NUM='ps -ef | grep "$1" | grep -v "grep" | wc -l'

to:

PROCESS_NUM=$(ps -ef | grep "$1" | grep -v "grep" | wc -l)

If you are expecting 4 as output then try this:

char a[]={0x00,0xdc,0x01,0x04};

In java synchronization,if a thread want to enter into synchronization method it will acquire lock on all synchronized methods of that object not just on one synchronized method that thread is using. So a thread executing addA() will acquire lock on addA() and addB() as both are synchronized.So other threads with same object cannot execute addB().

bmleite has the correct answer about including the module.

If that is correct in your situation, you should also ensure that you are not redefining the modules in multiple files.

Remember:

angular.module('ModuleName', [])   // creates a module.

angular.module('ModuleName')       // gets you a pre-existing module.

So if you are extending a existing module, remember not to overwrite when trying to fetch it.

Take your pick:

$ cat file
eth0      Link encap:Ethernet  HWaddr 08:00:27:a3:e3:b0
          inet addr:192.168.1.103  Bcast:192.168.1.255  Mask:255.255.255.0

          RX bytes:1309425 (1.2 MiB)  T

$ awk 'sub(/inet addr:/,""){print $1}' file
192.168.1.103

$ awk -F'[ :]+' '/inet addr/{print $4}' file
192.168.1.103

All the other answers didn't work for me. (including cors package, or setting headers through middleware)

For socket.io 3^ this worked without any extra packages.

const express = require('express');
const app = express();

const server = require('http').createServer(app);
const io = require('socket.io')(server, {
    cors: {
        origin: "*",
        methods: ["GET", "POST"]
    }
});

There is another instance still same error will shown after you doing everything above mentioned. When you change your codes accordingly mentioned solutions make sure to keep originals. So you can easily go back. So go and again check dispatcher-servelet configuration file's base package location. Is it scanning all relevant packages when you running application.

<context:component-scan base-package="your.pakage.path.here"/>

Three years past since this question was answered but I will provide my answer anyway :)

Actually, accepted answer is not fully correct. Jakub's test uses hardcoded string which allows JS engine to optimize code execution (Google's V8 is really good in this stuff!). But as soon as you use completely random strings (here is JSPerf) then string concatenation will be on a second place.

@momo's answer for Apache HttpClient, version 4.3.1 or later. I'm using JSON-Java to build my JSON object:

JSONObject json = new JSONObject();
json.put("someKey", "someValue");    

CloseableHttpClient httpClient = HttpClientBuilder.create().build();

try {
    HttpPost request = new HttpPost("http://yoururl");
    StringEntity params = new StringEntity(json.toString());
    request.addHeader("content-type", "application/json");
    request.setEntity(params);
    httpClient.execute(request);
// handle response here...
} catch (Exception ex) {
    // handle exception here
} finally {
    httpClient.close();
}

According to your package.json, you're using Angular 8.3, but you've imported angular/cdk v9. You can downgrade your angular/cdk version or you can upgrade your Angular version to v9 by running:

ng update @angular/core @angular/cli

That will update your local angular version to 9. Then, just to sync material, run: ng update @angular/material

Another way is to use the mysqlimport client program.

You invoke it as follows:

mysqlimport -uTheUsername -pThePassword --local yourDatabaseName tableName.txt

This generates a LOAD DATA statement which loads tableName.txt into the tableName table.

Keep in mind the following:

mysqlimport determines the table name from the file you provide; using all text from the start of the file name up to the first period as the table name. So, if you wish to load several files to the same table you could distinguish them like tableName.1.txt, tableName.2.txt,..., etc, for example.

ToTitleCase() should work for you.

http://support.microsoft.com/kb/312890

Use double braces {{ or }} so your code becomes:

sb.AppendLine(String.Format("public {0} {1} {{ get; private set; }}", 
prop.Type, prop.Name));

// For prop.Type of "Foo" and prop.Name of "Bar", the result would be:
// public Foo Bar { get; private set; }

->List all the packages by :

adb shell su 0 pm list packages -f

->Search for your package name by holding keys "ctrl+alt+f".

->Once found, look for the location associated with it.

This works well:

function test(el){
  el.childNodes.item("child").style.display = "none";
}

If the argument of item() function is an integer, the function will treat it as an index. If the argument is a string, then the function searches for name or ID of element.

You can use islower() on your string to see if it contains some lowercase letters (amongst other characters). or it with isupper() to also check if contains some uppercase letters:

below: letters in the string: test yields true

>>> z = "(555) 555 - 5555 ext. 5555"
>>> z.isupper() or z.islower()
True

below: no letters in the string: test yields false.

>>> z= "(555).555-5555"
>>> z.isupper() or z.islower()
False
>>> 

Not to be mixed up with isalpha() which returns True only if all characters are letters, which isn't what you want.

Note that Barm's answer completes mine nicely, since mine doesn't handle the mixed case well.

If they have just changed the oncontextmenu handler (which is the most straightforward way to do it), then you can remove their override thus:

window.oncontextmenu = null;

Otherwise, if it is attached to individual elements, you can get all the page's elements, and then remove the handler on each one:

var elements = document.getElementsByTagName("*");
for(var id = 0; id < elements.length; ++id) { elements[id].oncontextmenu = null; }

Or, it seems you can turn off such scripts; via an extension in Chrome or an option in Firefox - in the advanced box for javascript options, switch off 'Disable or replace context menus'.

As a general rule, converting a Web Forms or MVC5 application to ASP.NET Core will require a significant amount of refactoring.

HttpContext.Current was removed in ASP.NET Core. Accessing the current HTTP context from a separate class library is the type of messy architecture that ASP.NET Core tries to avoid. There are a few ways to re-architect this in ASP.NET Core.

HttpContext property

You can access the current HTTP context via the HttpContext property on any controller. The closest thing to your original code sample would be to pass HttpContext into the method you are calling:

public class HomeController : Controller
{
    public IActionResult Index()
    {
        MyMethod(HttpContext);

        // Other code
    }
}

public void MyMethod(Microsoft.AspNetCore.Http.HttpContext context)
{
    var host = $"{context.Request.Scheme}://{context.Request.Host}";

    // Other code
}

HttpContext parameter in middleware

If you're writing custom middleware for the ASP.NET Core pipeline, the current request's HttpContext is passed into your Invoke method automatically:

public Task Invoke(HttpContext context)
{
    // Do something with the current HTTP context...
}

HTTP context accessor

Finally, you can use the IHttpContextAccessor helper service to get the HTTP context in any class that is managed by the ASP.NET Core dependency injection system. This is useful when you have a common service that is used by your controllers.

Request this interface in your constructor:

public MyMiddleware(IHttpContextAccessor httpContextAccessor)
{
    _httpContextAccessor = httpContextAccessor;
}

You can then access the current HTTP context in a safe way:

var context = _httpContextAccessor.HttpContext;
// Do something with the current HTTP context...

IHttpContextAccessor isn't always added to the service container by default, so register it in ConfigureServices just to be safe:

public void ConfigureServices(IServiceCollection services)
{
    services.AddHttpContextAccessor();
    // if < .NET Core 2.2 use this
    //services.TryAddSingleton<IHttpContextAccessor, HttpContextAccessor>();

    // Other code...
}

If you're targeting HTML5 only you can use:

<input type="text" id="firstname" placeholder="First Name:" />

For non HTML5 browsers, I would build upon Floern's answer by using jQuery and make the javascript non-obtrusive. I would also use a class to define the blurred properties.

$(document).ready(function () {

    //Set the initial blur (unless its highlighted by default)
    inputBlur($('#Comments'));

    $('#Comments').blur(function () {
        inputBlur(this);
    });
    $('#Comments').focus(function () {
        inputFocus(this);
    });

})

Functions:

function inputFocus(i) {
    if (i.value == i.defaultValue) {
        i.value = "";
        $(i).removeClass("blurredDefaultText");
    }
}
function inputBlur(i) {
    if (i.value == "" || i.value == i.defaultValue) {
        i.value = i.defaultValue;
        $(i).addClass("blurredDefaultText");
    }
}

CSS:

.blurredDefaultText {
    color:#888 !important;
}

My simple solution to test if a string is null:

if (s.equals("null")){ ..... }

There are two cases.

The variable (of type String) is null(doesn't exists): == works.

The variable has a null value, *.equals("null") gives te right boolean value.

See the picture.

Since the question is not directly mentioning Visual Studio, I will post how to do this in JetBrains Rider.

From context menu

1. Right-click your project
2. Go to edit
3. Edit '{project-name.csproj}'

With shortcut

1. Select project
2. Press F4

Swift 4.2 example:

let group = DispatchGroup.group(count: 2)
group.notify(queue: DispatchQueue.main) {
     self.renderingLine = false
     // all groups are done
}
DispatchQueue.main.async {
    self.renderTargetNode(floorPosition: targetPosition, animated: closedContour) {
        group.leave()
        // first done
    }
    self.renderCenterLine(position: targetPosition, animated: closedContour) {
        group.leave()
        // second done
    }
 }

$(this).click(function(e) {
    // does something
});

In reference to the above code
$(this) is the element which as some variable.
click is the event that needs to be performed.
the parameter e is automatically passed from js to your function which holds the value of $(this) value and can be used further in your code to do some operation.

I too got the same error, when I did this behind a proxy. But after I exported the following from a terminal and re-tried the same command, the problem got resolved:

export http_proxy="http://username:password@proxy_ip_addr:port/"
export https_proxy="https://username:password@proxy_ip_addr:port/"

Similar to some of the answers, but not really stated, is to add a class to the actual option tag and use css classes...this is currently working for me without issue on IE (see above ss).

<select id="reviewAction">
<option class="greenColor">Accept and Advance Status</option>
<option class="redColor">Return for Modifications</option>
</select>

CSS:

.greenColor{
    background-color: #33CC33;
}
.redColor{
    background-color: #E60000;
}

A few more:

• blitwizard
• load81
• egsl

I got same error and it was due to older Lombok version. Check and update your Lombok version, Changes in Lombok

v1.18.4 - Many improvements for lombok's JDK10/11 support.

No you don't need to call the base destructor, a base destructor is always called for you by the derived destructor. Please see my related answer here for order of destruction.

To understand why you want a virtual destructor in the base class, please see the code below:

class B
{
public:
    virtual ~B()
    {
        cout<<"B destructor"<<endl;
    }
};


class D : public B
{
public:
    virtual ~D()
    {
        cout<<"D destructor"<<endl;
    }
};

When you do:

B *pD = new D();
delete pD;

Then if you did not have a virtual destructor in B, only ~B() would be called. But since you have a virtual destructor, first ~D() will be called, then ~B().

we can use express-session to send the required data

when you initialise the app

const express = require('express');
const app = express();
const session = require('express-session');
app.use(session({secret: 'mySecret', resave: false, saveUninitialized: false}));

so before redirection just save the context for the session

app.post('/category', function(req, res) {
    // add your context here 
req.session.context ='your context here' ;
    res.redirect('/');
});

Now you can get the context anywhere for the session. it can get just by req.session.context

app.get('/', function(req, res) {

    // So prepare the context
var context=req.session.context;
    res.render('home.jade', context);
});

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

wget -q --spider address
echo $?

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

The map file maps the unminified file to the minified file. If you make changes in the unminified file, the changes will be automatically reflected to the minified version of the file.

Named instances?

URL: jdbc:sqlserver://[serverName][\instanceName][:portNumber][;property=value]

Note: backward slash

you can get the value of the respective li by using this method after click

HTML:-

<!DOCTYPE html>
<html>
<head>
    <title>show the value of li</title>
    <link rel="stylesheet"  href="pathnameofcss">

One more thing - TemplateBindings don't allow value converting. They don't allow you to pass a Converter and don't automatically convert int to string for example (which is normal for a Binding).

text-align: center will only work for horizontal centering. For it to be in the complete center, vertical and horizontal you can do the following :

div
{
    position: relative;
}
div img
{
    position: absolute;
    top: 50%;
    left: 50%;
    margin-left: [-50% of your image's width];
    margin-top: [-50% of your image's height];
}

Let's not over complicate what should be a very simple answer. Methods and functions are the same thing. You call a function a function when it is outside of a class, and you call a function a method when it is written inside a class.

It worked for me, hope you too.

*Note: I have used auto layout in Nib, remember add top and bottom contraints for subviews in contentView

func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
           let cell = YourCollectionViewCell.instantiateFromNib()
           cell.frame.size.width = collectionView.frame.width
           cell.data = viewModel.data[indexPath.item]
           let resizing = cell.systemLayoutSizeFitting(UILayoutFittingCompressedSize, withHorizontalFittingPriority: UILayoutPriority.required, verticalFittingPriority: UILayoutPriority.fittingSizeLevel)
           return resizing
    }

I would say that the easiest way is to use transparent background image.

http://jsfiddle.net/m48nH/

background: url("http://musescore.org/sites/musescore.org/files/blue-translucent.png") repeat top left;

I had the same problem, and xmltable helped me:

SELECT id, trim(COLUMN_VALUE) text FROM t, xmltable(('"' || REPLACE(text, ',', '","') || '"'))

Here is another option

$array = [1=>'one', 2=>'two', 3=>'there'];
$array = array_flip($array);
echo $array['one']; 

You can mix up the post argument by using body and path variable for simpler data types:

@RequestMapping(value = "new-trade/portfolio/{portfolioId}", method = RequestMethod.POST)
    public ResponseEntity<List<String>> newTrade(@RequestBody Trade trade, @PathVariable long portfolioId) {
...
}

Sorry to bump an old question but the answer is to count the character length of the cell and not its value.

CellCount = Cells(Row, 10).Value
If Len(CellCount) <= "13" Then
'do something
End If

hope that helps. Cheers

Most probably the answer is to install MySQL Developer Build and selecting "C headers\libs" option during configuration. (as reported in this entry: Building MySQLdb for Python on Windows on rationalpie.wordpress.com)

Maybe even better solution is to install a precompiled build: http://www.technicalbard.com/files/MySQL-python-1.2.2.win32-py2.6.exe

You could achieve that simply by wrapping the image by a <div> and adding overflow: hidden to that element:

<div class="img-wrapper">
    <img src="..." />
</div>

.img-wrapper {
    display: inline-block; /* change the default display type to inline-block */
    overflow: hidden;      /* hide the overflow */
}

WORKING DEMO.

Also it's worth noting that <img> element (like the other inline elements) sits on its baseline by default. And there would be a 4~5px gap at the bottom of the image.

That vertical gap belongs to the reserved space of descenders like: g j p q y. You could fix the alignment issue by adding vertical-align property to the image with a value other than baseline.

Additionally for a better user experience, you could add transition to the images.

Thus we'll end up with the following:

.img-wrapper img {
    transition: all .2s ease;
    vertical-align: middle;
}

UPDATED DEMO.

I've got into same problem. None of the above solutions worked for me.

So, I've excluded the files which failed to copy while publishing.

I wrote a tool to capture images from a webcam entirely in Python, based on DirectShow. You can find it here: https://github.com/andreaschiavinato/python_grabber.

You can use the whole application or just the class FilterGraph in dshow_graph.py in the following way:

from pygrabber.dshow_graph import FilterGraph
import numpy as np
from matplotlib.image import imsave

graph = FilterGraph()
print(graph.get_input_devices())
device_index = input("Enter device number: ")
graph.add_input_device(int(device_index))
graph.display_format_dialog()
filename = r"c:\temp\imm.png"
# np.flip(image, axis=2) required to convert image from BGR to RGB
graph.add_sample_grabber(lambda image : imsave(filename, np.flip(image, axis=2)))
graph.add_null_render()
graph.prepare()
graph.run()
x = input("Press key to grab photo")
graph.grab_frame()
x = input(f"File {filename} saved. Press key to end")
graph.stop()

Try to handler 'mousewheel' event on all nodes except one

$('body').on({
    'mousewheel': function(e) {
        if (e.target.id == 'el') return;
        e.preventDefault();
        e.stopPropagation();
    }
})

Demo: http://jsfiddle.net/DHz77/1/

This issue is still present in Mac Office 2011 and Office 2013, I cannot prevent it happening. It seems such a basic thing.

In my case I had values such as "1 - 2" & "7 - 12" within the CSV enclosed correctly within inverted commas, this automatically converts to a date within excel, if you try subsequently convert it to just plain text you would get a number representation of the date such as 43768. Additionally it reformats large numbers found in barcodes and EAN numbers to 123E+ numbers again which cannot be converted back.

I have found that Google Drive's Google Sheets doesnt convert the numbers to dates. The barcodes do have commas in them every 3 characters but these are easily removed. It handles CSVs really well especially when dealing with MAC / Windows CSVs.

Might save someone sometime.

Edit 2018-05-28 I have changed the example to use Java 8's Time API:

LocalDate d1 = LocalDate.parse("2018-05-26", DateTimeFormatter.ISO_LOCAL_DATE);
LocalDate d2 = LocalDate.parse("2018-05-28", DateTimeFormatter.ISO_LOCAL_DATE);
Duration diff = Duration.between(d1.atStartOfDay(), d2.atStartOfDay());
long diffDays = diff.toDays();

I have 2 accounts on github, and here is what I did (on linux) to make it work.

Keys

• Create 2 pair of rsa keys, via ssh-keygen, name them properly, so that make life easier.
• Add private keys to local agent via ssh-add path_to_private_key
• For each github account, upload a (distinct) public key.

Configuration

~/.ssh/config

Host github-kc
    Hostname        github.com
    User git
    IdentityFile    ~/.ssh/github_rsa_kc.pub
    # LogLevel DEBUG3

Host github-abc
    Hostname        github.com
    User git
    IdentityFile    ~/.ssh/github_rsa_abc.pub
    # LogLevel DEBUG3

Set remote url for repo:

• For repo in Host github-kc:

  git remote set-url origin git@github-kc:kuchaguangjie/pygtrans.git
  

• For repo in Host github-abc:

  git remote set-url origin git@github-abc:abcdefg/yyy.git
  

Explaination

Options in ~/.ssh/config:

• Host github-<identify_specific_user>
  Host could be any value that could identify a host plus an account, it don't need to be a real host, e.g github-kc identify one of my account on github for my local laptop,
  

  When set remote url for a git repo, this is the value to put after git@, that's how a repo maps to a Host, e.g git remote set-url origin git@github-kc:kuchaguangjie/pygtrans.git

• 
  
• [Following are sub options of Host]
• Hostname
  specify the actual hostname, just use github.com for github,
• User git
  the user is always git for github,
• IdentityFile
  specify key to use, just put the path the a public key,
• LogLevel
  specify log level to debug, if any issue, DEBUG3 gives the most detailed info.

var postData = "text";
      $.ajax({
            type: "post",
            url: "url",
            data: postData,
            contentType: "application/x-www-form-urlencoded",
            success: function(responseData, textStatus, jqXHR) {
                alert("data saved")
            },
            error: function(jqXHR, textStatus, errorThrown) {
                console.log(errorThrown);
            }
        })

You have an error in your syntax here:

this._possessions = new Thing[100]();

This doesn't create an "array of things". To create an array of things, you can simply use the array literal expression:

this._possessions = [];

Of the array constructor if you want to set the length:

this._possessions = new Array(100);

I have created a brief working example you can try in the playground.

module Entities {  

    class Thing {

    }        

    export class Person {
        private _name: string;
        private _possessions: Thing[];
        private _mostPrecious: Thing;

        constructor (name: string) {
            this._name = name;
            this._possessions = [];
            this._possessions.push(new Thing())
            this._possessions[100] = new Thing();
        }
    }
}

I took this to another level. Chucking is an easy one liner, but in my case I needed whole words as well. Figured I would post it, just in case someone else needs something similar.

static IEnumerable<string> Split(string orgString, int chunkSize, bool wholeWords = true)
{
    if (wholeWords)
    {
        List<string> result = new List<string>();
        StringBuilder sb = new StringBuilder();

        if (orgString.Length > chunkSize)
        {
            string[] newSplit = orgString.Split(' ');
            foreach (string str in newSplit)
            {
                if (sb.Length != 0)
                    sb.Append(" ");

                if (sb.Length + str.Length > chunkSize)
                {
                    result.Add(sb.ToString());
                    sb.Clear();
                }

                sb.Append(str);
            }

            result.Add(sb.ToString());
        }
        else
            result.Add(orgString);

        return result;
    }
    else
        return new List<string>(Regex.Split(orgString, @"(?<=\G.{" + chunkSize + "})", RegexOptions.Singleline));
}

Results based on below comment:

string msg = "336699AABBCCDDEEFF";
foreach (string newMsg in Split(msg, 2, false))
{
    Console.WriteLine($">>{newMsg}<<");
}

Console.ReadKey();

Results:

Another way to pull it:

List<string> splitData = (List<string>)Split(msg, 2, false);

for (int i = 0; i < splitData.Count - 1; i++)
{
    Console.WriteLine($">>{splitData[i]}<<");
}

Here's my solution:

public static class EnumerationExtensions
{
    public static IEnumerable<T> TakeLast<T>(this IEnumerable<T> input, int count)
    {
        if (count <= 0)
            yield break;

        var inputList = input as IList<T>;

        if (inputList != null)
        {
            int last = inputList.Count;
            int first = last - count;

            if (first < 0)
                first = 0;

            for (int i = first; i < last; i++)
                yield return inputList[i];
        }
        else
        {
            // Use a ring buffer. We have to enumerate the input, and we don't know in advance how many elements it will contain.
            T[] buffer = new T[count];

            int index = 0;

            count = 0;

            foreach (T item in input)
            {
                buffer[index] = item;

                index = (index + 1) % buffer.Length;
                count++;
            }

            // The index variable now points at the next buffer entry that would be filled. If the buffer isn't completely
            // full, then there are 'count' elements preceding index. If the buffer *is* full, then index is pointing at
            // the oldest entry, which is the first one to return.
            //
            // If the buffer isn't full, which means that the enumeration has fewer than 'count' elements, we'll fix up
            // 'index' to point at the first entry to return. That's easy to do; if the buffer isn't full, then the oldest
            // entry is the first one. :-)
            //
            // We'll also set 'count' to the number of elements to be returned. It only needs adjustment if we've wrapped
            // past the end of the buffer and have enumerated more than the original count value.

            if (count < buffer.Length)
                index = 0;
            else
                count = buffer.Length;

            // Return the values in the correct order.
            while (count > 0)
            {
                yield return buffer[index];

                index = (index + 1) % buffer.Length;
                count--;
            }
        }
    }

    public static IEnumerable<T> SkipLast<T>(this IEnumerable<T> input, int count)
    {
        if (count <= 0)
            return input;
        else
            return input.SkipLastIter(count);
    }

    private static IEnumerable<T> SkipLastIter<T>(this IEnumerable<T> input, int count)
    {
        var inputList = input as IList<T>;

        if (inputList != null)
        {
            int first = 0;
            int last = inputList.Count - count;

            if (last < 0)
                last = 0;

            for (int i = first; i < last; i++)
                yield return inputList[i];
        }
        else
        {
            // Aim to leave 'count' items in the queue. If the input has fewer than 'count'
            // items, then the queue won't ever fill and we return nothing.

            Queue<T> elements = new Queue<T>();

            foreach (T item in input)
            {
                elements.Enqueue(item);

                if (elements.Count > count)
                    yield return elements.Dequeue();
            }
        }
    }
}

The code is a bit chunky, but as a drop-in reusable component, it should perform as well as it can in most scenarios, and it'll keep the code that's using it nice and concise. :-)

My TakeLast for non-IList`1 is based on the same ring buffer algorithm as that in the answers by @Mark Byers and @MackieChan further up. It's interesting how similar they are -- I wrote mine completely independently. Guess there's really just one way to do a ring buffer properly. :-)

Looking at @kbrimington's answer, an additional check could be added to this for IQuerable<T> to fall back to the approach that works well with Entity Framework -- assuming that what I have at this point does not.

Just in case you're a performance freak...

The Fastest way (in JavaScript) to compute a rectangle ratio it o use a true binary Great Common Divisor algorithm.

Easiest thing is input it as a "div" give it a "margin:0 auto " but if you want it to be centered u need to give it a width

  Div{
   Margin: 0 auto ;
   Width: 100px ;
  }

there are two projects that allow an "obvious" transition between python objects and javascript objects, with "obvious" translations from int or float to Number and str or unicode to String: PyV8 and, as one writer has already mentioned: python-spidermonkey.

there are actually two implementations of pyv8 - the original experiment was by sebastien louisel, and the second one (in active development) is by flier liu.

my interest in these projects has been to link them to pyjamas, a python-to-javascript compiler, to create a JIT python accelerator.

so there is plenty out there - it just depends what you want to do.

Try this: "COPY products_273 FROM '\tmp\products_199.csv' DELIMITER ',' CSV HEADER"

The simplest thing you can do is use reset.css. It normalizes the default stylesheet across browsers, and coincidentally allows button { vertical-align: middle; } to work just fine. Give it a shot - I use it in virtually all of my projects just to kill little bugs like this.

Simple solution, just one line..

var obj = {
    "set1": [1, 2, 3],
    "set2": [4, 5, 6, 7, 8],
    "set3": [9, 10, 11, 12]
};

obj = Object.values(obj);

obj[1]....

If you create an object, you get a more readable output and also gain an object with properties you can access:

$path = 'HKLM:\SOFTWARE\Wow6432Node\Microsoft\.NETFramework'
$obj  = New-Object -TypeName psobject

Get-Item -Path $path | Select-Object -ExpandProperty Property | Sort | % {
$command = [String]::Format('(Get-ItemProperty -Path "{0}" -Name "{1}")."{1}"', $path, $_)
$value = Invoke-Expression -Command $command
$obj | Add-Member -MemberType NoteProperty -Name $_ -Value $value}

Write-Output $obj | fl

Sample output: InstallRoot : C:\Windows\Microsoft.NET\Framework\

And the object: $obj.InstallRoot = C:\Windows\Microsoft.NET\Framework\

The truth of the matter is this is way more complicated than it needs to be. Here is a much better example, and much simpler:

$path = 'HKLM:\SOFTWARE\Wow6432Node\Microsoft\.NETFramework'
$objReg = Get-ItemProperty -Path $path | Select -Property *

$objReg is now a custom object where each registry entry is a property name. You can view the formatted list via:

write-output $objReg

InstallRoot        : C:\Windows\Microsoft.NET\Framework\
DbgManagedDebugger : "C:\windows\system32\vsjitdebugger.exe"

And you have access to the object itself:

$objReg.InstallRoot
C:\Windows\Microsoft.NET\Framework\

There's a bit of a hack for this, since the HTML5 canvas is required to parse color values when certain properties like strokeStyle and fillStyle are set:

var ctx = document.createElement('canvas').getContext('2d');
ctx.strokeStyle = 'rgb(64, 128, 192)';
var hexColor = ctx.strokeStyle;

I'm going to say that it is not possible to completely prevent screen/video capture of any android app through supported means. But if you only want to block it for normal android devices, the SECURE FLAG is substantial.

1) The secure flag does block both normal screenshot and video capture.

Also documentation at this link says that

Window flag: treat the content of the window as secure, preventing it from appearing in screenshots or from being viewed on non-secure displays.

Above solution will surely prevent applications from capturing Video of your app

See the answer here.

2) There are alternative means of capturing screen content.

It may be possible to capture the screen of another app on a rooted device or through using the SDK,

which both offer little to no chance of you either blocking it or receiving notification of it.

For example: there exists software to mirror your phone screen to your computer via the SDK and so screen capture software could be used there, undiscoverable by your app.

See the answer here.

getWindow().setFlags(LayoutParams.FLAG_SECURE, LayoutParams.FLAG_SECURE);

There is a simple, easy and better approach, if we need to change only the color of hamburger/back icon.

It is better as it changes color only of desired icon, whereas colorControlNormal and android:textColorSecondary might affect other childviews of toolbar as well.

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="drawerArrowStyle">@style/DrawerArrowStyle</item>

    <item name="color">@android:color/white</item>

Firstly a class and its collaborators should firstly perform their intended purpose rather than focusing on dependents. Lifecycle management (when instances are created and when they go out of scope) should not be part of the classes responsibility. The accepted best practice for this is to craft or configure a new component to manage dependencies using dependency injection.

Often software gets more complicated it makes sense to have multiple independent instances of the Singleton class with different state. Committing code to simply grab the singleton is wrong in such cases. Using Singleton.getInstance() might be ok for small simple systems but it doesn't work/scale when one might need a different instance of the same class.

No class should be thought of as a singleton but rather that should be an application of it's usage or how it is used to configure dependents. For a quick and nasty this does not matter - just luke hard coding say file paths does not matter but for bigger applications such dependencies need to be factored out and managed in more appropriate way using DI.

The problems that singleton cause in testing is a symptom of their hard coded single usage case/environment. The test suite and the many tests are each individual and separate something that is not compatible with hard coding a singleton.

As You're getting values from textfield as jTextField3.getText();.

As it is a textField it will return you string format as its format says:

String getText()

      Returns the text contained in this TextComponent.

So, convert your String to Integer as:

int jml = Integer.parseInt(jTextField3.getText());

instead of directly setting

   int jml = jTextField3.getText();

import time

def add_month(start_time, months):  

        ret = time.strptime(start_time, '%Y-%m-%d')
        t = list(ret)

        t[1] += months

        if t[1] > 12:
            t[0] += 1 + int(months / 12)

            t[1] %= 12

        return int(time.mktime(tuple(t)))

If You want to have a reference to this variable across the whole project, create somewhere d.ts file, e.g. globals.d.ts. Fill it with your global variables declarations, e.g.:

declare const BootBox: 'boot' | 'box';

Now you can reference it anywhere across the project, just like that:

const bootbox = BootBox;

Here's an example.

Enums in C++ are like integers masked by the names you give them, when you declare your enum-values (this is not a definition only a hint how it works).

But there are two errors in your code:

1. Spell enum all lower case
2. You don't need the Days. before Saturday.
3. If this enum is declared in a class, then use if (day == YourClass::Saturday){}

You could utilize jQuery.filter() function to return elements from a subset of the matching elements.

var names = [_x000D_
    { name : "Joe", age:20, email: "[email protected]"},_x000D_
    { name : "Mike", age:50, email: "[email protected]"},_x000D_
    { name : "Joe", age:45, email: "[email protected]"}_x000D_
   ];_x000D_
   _x000D_
   _x000D_
var filteredNames = $(names).filter(function( idx ) {_x000D_
    return names[idx].name === "Joe" && names[idx].age < 30;_x000D_
}); _x000D_
_x000D_
$(filteredNames).each(function(){_x000D_
     $('#output').append(this.name);_x000D_
});

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

Whatever Apple ships as the default gcc in xcode (4.2.1 on 10.6, 4.0.1 before) is well tested (and maintained) by the apple guys and the "standard" to build software with on OS X. Everything else is not, so think twice if you want to develop software, or be gcc/OS X beta tester.

Since Symfony 3.3 you can use binding, like

services:
_defaults:
    autowire: true      
    autoconfigure: true
    bind:
        $kernelProjectDir: '%kernel.project_dir%'

After that you can use parameter $kernelProjectDir in any controller OR service. Just like

class SomeControllerOrService
{
    public function someAction(...., $kernelProjectDir)
    {
          .....

If you're on a Unix-like system, use gettimeofday and convert the result from microseconds to milliseconds.

The difference is in the subsystem that each executable targets.

• java.exe targets the CONSOLE subsystem.
• javaw.exe targets the WINDOWS subsystem.

I solved it this way.. I have basically a simple view inside xml file.

 View viewname = findViewById(R.id.prod_extra);
             prodExtra.getLayoutParams().height=64;

For those interested, there is no:

<xsl:tag-of select="."/>

However you can re-create the tag/element by going:

<xsl:element name="{local-name()}">
  <xsl:value-of select="substring(.,1,3)"/>
</xsl:element>

This is useful in an xslt template that for example handles formatting data values for lots of different elements. When you don't know the name of the element being worked on and you can still output the same element, and modify the value if need be.

If you only want the create tables, then you can do pg_dump -s databasename | awk 'RS="";/CREATE TABLE[^;]*;/'

To get a fully independent copy of an object you can use the copy.deepcopy() function.

For more details about shallow and deep copying please refer to the other answers to this question and the nice explanation in this answer to a related question.

function filesModelDirective(){
  return {
    controller: function($parse, $element, $attrs, $scope){
      var exp = $parse($attrs.filesModel);
      $element.on('change', function(){
        exp.assign($scope, this.files[0]);
        $scope.$apply();
      });
    }
  };
}
app.directive('filesModel', filesModelDirective);

With IntelliJ, you can do this from the test configuration. Once you open this window, you can choose to run the test any number of times you want,.

when you run the test, intellij will execute all tests you have selected for the number of times you specified.

Example running 624 tests 10 times:

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

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

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

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

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

The HttpWebRequest modifies the CookieContainer assigned to it. There is no need to process returned cookies. Simply assign your cookie container to every web request.

public class CookieAwareWebClient : WebClient
{
    public CookieContainer CookieContainer { get; set; } = new CookieContainer();

    protected override WebRequest GetWebRequest(Uri uri)
    {
        WebRequest request = base.GetWebRequest(uri);
        if (request is HttpWebRequest)
        {
            (request as HttpWebRequest).CookieContainer = CookieContainer;
        }
        return request;
    }
}

If they are not hashable, you can sort them and do a single loop over the result counting the items (identical items will be next to each other). But it might be faster to make them hashable and use a dict.

def most_common(lst):
    cur_length = 0
    max_length = 0
    cur_i = 0
    max_i = 0
    cur_item = None
    max_item = None
    for i, item in sorted(enumerate(lst), key=lambda x: x[1]):
        if cur_item is None or cur_item != item:
            if cur_length > max_length or (cur_length == max_length and cur_i < max_i):
                max_length = cur_length
                max_i = cur_i
                max_item = cur_item
            cur_length = 1
            cur_i = i
            cur_item = item
        else:
            cur_length += 1
    if cur_length > max_length or (cur_length == max_length and cur_i < max_i):
        return cur_item
    return max_item

What you have is correct, though you will not call it global, it is a class attribute and can be accessed via class e.g Shape.lolwut or via an instance e.g. shape.lolwut but be careful while setting it as it will set an instance level attribute not class attribute

class Shape(object):
    lolwut = 1

shape = Shape()

print Shape.lolwut,  # 1
print shape.lolwut,  # 1

# setting shape.lolwut would not change class attribute lolwut 
# but will create it in the instance
shape.lolwut = 2

print Shape.lolwut,  # 1
print shape.lolwut,  # 2

# to change class attribute access it via class
Shape.lolwut = 3

print Shape.lolwut,  # 3
print shape.lolwut   # 2 

output:

1 1 1 2 3 2

Somebody may expect output to be 1 1 2 2 3 3 but it would be incorrect

Unlike stated previously 'preceding-sibling' is really the axis to use, not 'preceding' which does something completely different, it selects everything in the document that is before the start tag of the current node. (see http://www.w3schools.com/xpath/xpath_axes.asp)

one short way would be

$id = $this -> db
       -> select('id')
       -> where('email', $email)
       -> limit(1)
       -> get('users')
       -> row()
       ->id;
echo "ID is ".$id;

Keep in mind that relative URLs are resolved from the URL of your stylesheet.

So it will work if folder images is inside the stylesheets folder.

From you description you would need to change it to either

url("../images/plaid.jpg")

or

url("/images/plaid.jpg") 

Additional 1

Also you cannot have no selector..

CSS is applied through selectors..

Additional 2

You should use either the shorthand background to pass multiple values like this

background: url("../images/plaid.jpg") no-repeat;

or the verbose syntax of specifying each property on its own

background-image: url("../images/plaid.jpg");
background-repeat:no-repeat;

solution is very simple if you are using asp.net core 2 application . Inside ConfigureServices method inside startup.cs file all this line

services.AddMvc()
                .SetCompatibilityVersion(CompatibilityVersion.Version_2_1)
                .AddJsonOptions(x => x.SerializerSettings.ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore);

This is a matplotlib question, and you can get around this by using a backend that doesn't display to the user, e.g. 'Agg':

import matplotlib
matplotlib.use('Agg')
import matplotlib.pyplot as plt

plt.plot([1,2,3])
plt.savefig('/tmp/test.png')

EDIT: If you don't want to lose the ability to display plots, turn off Interactive Mode, and only call plt.show() when you are ready to display the plots:

import matplotlib.pyplot as plt

# Turn interactive plotting off
plt.ioff()

# Create a new figure, plot into it, then close it so it never gets displayed
fig = plt.figure()
plt.plot([1,2,3])
plt.savefig('/tmp/test0.png')
plt.close(fig)

# Create a new figure, plot into it, then don't close it so it does get displayed
plt.figure()
plt.plot([1,3,2])
plt.savefig('/tmp/test1.png')

# Display all "open" (non-closed) figures
plt.show()

Take a look at the sqlcmd utility. It allows you to execute SQL from the command line.

http://msdn.microsoft.com/en-us/library/ms162773.aspx

It's all in there in the documentation, but the syntax should look something like this:

sqlcmd -U myLogin -P myPassword -S MyServerName -d MyDatabaseName 
    -Q "DROP TABLE MyTable"

Assuming that ID is an identity column:

INSERT INTO TheTable(HospitalID, Email, Description)
SELECT 32, Email, Description FROM TheTable
WHERE HospitalID <> 32

Try to avoid loops with SQL. Try to think in terms of sets instead.

I recommend you start reading the documentation (4.6.18. Formatting cells). When applying a lot of formatting it's better to use applyFromArray() According to the documentation this method is also suppose to be faster when you're setting many style properties. There's an annex where you can find all the possible keys for this function.

This will work for you:

$phpExcel = new PHPExcel();

$styleArray = array(
    'font'  => array(
        'bold'  => true,
        'color' => array('rgb' => 'FF0000'),
        'size'  => 15,
        'name'  => 'Verdana'
    ));

$phpExcel->getActiveSheet()->getCell('A1')->setValue('Some text');
$phpExcel->getActiveSheet()->getStyle('A1')->applyFromArray($styleArray);

To apply font style to complete excel document:

 $styleArray = array(
   'font'  => array(
        'bold'  => true,
        'color' => array('rgb' => 'FF0000'),
        'size'  => 15,
        'name'  => 'Verdana'
    ));      
 $phpExcel->getDefaultStyle()
    ->applyFromArray($styleArray);

BASED ON LARAVEL 5.7 & ABOVE

To get all segments of current URL:

$current_uri = request()->segments();

To get segment posts from http://example.com/users/posts/latest/

NOTE: Segments are an array that starts at index 0. The first element of array starts after the TLD part of the url. So in the above url, segment(0) will be users and segment(1) will be posts.

//get segment 0
$segment_users = request()->segment(0); //returns 'users'
//get segment 1
$segment_posts = request()->segment(1); //returns 'posts'

You may have noted that the segment method only works with the current URL ( url()->current() ). So I designed a method to work with previous URL too by cloning the segment() method:

public function index()
{
    $prev_uri_segments = $this->prev_segments(url()->previous());
}

 /**
 * Get all of the segments for the previous uri.
 *
 * @return array
 */
public function prev_segments($uri)
{
    $segments = explode('/', str_replace(''.url('').'', '', $uri));

    return array_values(array_filter($segments, function ($value) {
        return $value !== '';
    }));
}

For me, ensuring that I had:

#include <iostream>  
#include<string>  
using namespace std;

in my file made something like to_string(12345) work.

If you want to separate the commands into one command per file, you can do

cmd /c start C:\Users\Yiwei\Downloads\putty.exe -load "MathCS-labMachine1"

and in the other file, you can do

cmd /c start "" "C:\Program Files (x86)\Xming\Xming.exe" :0 -clipboard -multiwindow

The command cmd /c will close the command-prompt window after the exe was run.

...and in case you wanted to link your main statically, in your Jamfile add the following to requirements:

<link>static
<library>/boost/system//boost_system

and perhaps also:

<linkflags>-static-libgcc
<linkflags>-static-libstdc++

I just compared Apache Commons Math with jlapack.

Test: singular value decomposition of a random 1024x1024 matrix.

Machine: Intel(R) Core(TM)2 Duo CPU E6750 @ 2.66GHz, linux x64

Octave code: A=rand(1024); tic;[U,S,V]=svd(A);toc

results                                execution time

Intel MKL                               6.89 sec(!)

My conclusion is that jlapack called from JDK 1.7 is very close to the native binary performance of lapack. I used the lapack binary library coming with linux distro and invoked the dgesvd routine to get the U,S and VT matrices as well. All tests were done using double precision on exactly the same matrix each run (except Octave).

Disclaimer - I'm not an expert in linear algebra, not affiliated to any of the libraries above and this is not a rigorous benchmark. It's a 'home-made' test, as I was interested comparing the performance increase of JDK 1.7 to 1.6 as well as commons math SVD to jlapack.

You have to declare height of html to div1 elements together, like:

html,
body,
.container,
.div1,
.div2 {
    height:100%;
}

Demo: http://jsfiddle.net/Ccham/

The following works how you want it, but it is not ideal.

public class Tester extends Activity {

    String[] vals = { "here", "are", "some", "values" };
    Spinner spinner;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        spinner = (Spinner) findViewById(R.id.spin);
        ArrayAdapter<String> ad = new ArrayAdapter<String>(this, android.R.layout.simple_dropdown_item_1line, vals);
        spinner.setAdapter(ad);
        Log.i("", "" + spinner.getChildCount());
        Timer t = new Timer();
        t.schedule(new TimerTask() {

            @Override
            public void run() {
                int a = spinner.getCount();
                int b = spinner.getChildCount();
                System.out.println("Count =" + a);
                System.out.println("ChildCount =" + b);
                for (int i = 0; i < b; i++) {
                    View v = spinner.getChildAt(i);
                    if (v == null) {
                        System.out.println("View not found");
                    } else {
                        v.setOnClickListener(new View.OnClickListener() {

                            @Override
                            public void onClick(View v) {
                                        Log.i("","click");
                                        }
                        });
                    }
                }
            }
        }, 500);
    }
}

Let me know exactly how you need the spinner to behave, and we can work out a better solution.

This way you get the intersection of two lists and also get the common duplicates.

>>> from collections import Counter
>>> a = Counter([1,2,3,4,5])
>>> b = Counter([1,3,5,6])
>>> a &= b
>>> list(a.elements())
[1, 3, 5]

Try this. (Here we use text=Lines to keep the example self contained but in reality we would replace it with the file name.)

Lines <- "2009-01  12
2009-02  310
2009-03  2379
2009-04  234
2009-05  14
2009-08  1
2009-09  34
2009-10  2386"

library(zoo)
z <- read.zoo(text = Lines, FUN = as.yearmon)
plot(z)

The X axis is not so pretty with this data but if you have more data in reality it might be ok or you can use the code for a fancy X axis shown in the examples section of ?plot.zoo .

The zoo series, z, that is created above has a "yearmon" time index and looks like this:

> z
Jan 2009 Feb 2009 Mar 2009 Apr 2009 May 2009 Aug 2009 Sep 2009 Oct 2009 
      12      310     2379      234       14        1       34     2386 

"yearmon" can be used alone as well:

> as.yearmon("2000-03")
[1] "Mar 2000"

Note:

1. "yearmon" class objects sort in calendar order.

2. This will plot the monthly points at equally spaced intervals which is likely what is wanted; however, if it were desired to plot the points at unequally spaced intervals spaced in proportion to the number of days in each month then convert the index of z to "Date" class: time(z) <- as.Date(time(z)) .

This will build and install both gtest and gmock 1.7.0:

mkdir /tmp/googleTestMock
tar -xvf googletest-release-1.7.0.tar.gz -C /tmp/googleTestMock
tar -xvf googlemock-release-1.7.0.tar.gz -C /tmp/googleTestMock

sudo cp -a gtest/libgtest.so gtest/libgtest_main.so /usr/lib/
sudo ldconfig

First, the ++ operator takes precedence over the * operator, and the () operators take precedence over everything else.

Second, the ++number operator is the same as the number++ operator if you're not assigning them to anything. The difference is number++ returns number and then increments number, and ++number increments first and then returns it.

Third, by increasing the value of a pointer, you're incrementing it by the sizeof its contents, that is you're incrementing it as if you were iterating in an array.

So, to sum it all up:

ptr++;    // Pointer moves to the next int position (as if it was an array)
++ptr;    // Pointer moves to the next int position (as if it was an array)
++*ptr;   // The value of ptr is incremented
++(*ptr); // The value of ptr is incremented
++*(ptr); // The value of ptr is incremented
*ptr++;   // Pointer moves to the next int position (as if it was an array). But returns the old content
(*ptr)++; // The value of ptr is incremented
*(ptr)++; // Pointer moves to the next int position (as if it was an array). But returns the old content
*++ptr;   // Pointer moves to the next int position, and then get's accessed, with your code, segfault
*(++ptr); // Pointer moves to the next int position, and then get's accessed, with your code, segfault

As there are a lot of cases in here, I might have made some mistake, please correct me if I'm wrong.

EDIT:

So I was wrong, the precedence is a little more complicated than what I wrote, view it here: http://en.cppreference.com/w/cpp/language/operator_precedence

You can use either one. But I think Sleep() is easy, clear and shorter to implement.

Friend functions and classes provide direct access to private and protected members of class to avoid breaking encapsulation in the general case. Most usage is with ostream: we would like to be able to type:

Point p;
cout << p;

However, this may require access to the private data of Point, so we define the overloaded operator

friend ostream& operator<<(ostream& output, const Point& p);

There are obvious encapsulation implications, however. First, now the friend class or function has full access to ALL members of the class, even ones that do not pertain to its needs. Second, the implementations of the class and the friend are now enmeshed to the point where an internal change in the class can break the friend.

If you view the friend as an extension of the class, then this is not an issue, logically speaking. But, in that case, why was it necessary to spearate out the friend in the first place.

To achieve the same thing that 'friends' purport to achieve, but without breaking encapsulation, one can do this:

class A
{
public:
    void need_your_data(B & myBuddy)
    {
        myBuddy.take_this_name(name_);
    }
private:
    string name_;
};

class B
{
public:
    void print_buddy_name(A & myBuddy)
    {
        myBuddy.need_your_data(*this);
    }
    void take_this_name(const string & name)
    {
        cout << name;
    }
}; 

Encapsulation is not broken, class B has no access to the internal implementation in A, yet the result is the same as if we had declared B a friend of A. The compiler will optimize away the function calls, so this will result in the same instructions as direct access.

I think using 'friend' is simply a shortcut with arguable benefit, but definite cost.

This can also be achieved using the Scalar-Valued Function in MSSQL 2008
Declare your function as following,

CREATE FUNCTION [dbo].[FunctionName]
(@MaskId INT)
RETURNS Varchar(500) 
AS
BEGIN

    DECLARE @SchoolName varchar(500)                        

    SELECT @SchoolName =ISNULL(@SchoolName ,'')+ MD.maskdetail +', ' 
    FROM maskdetails MD WITH (NOLOCK)       
    AND MD.MaskId=@MaskId

    RETURN @SchoolName

END

And then your final query will be like

SELECT m.maskid,m.maskname,m.schoolid,s.schoolname,
(SELECT [dbo].[FunctionName](m.maskid)) 'maskdetail'
FROM tblmask m JOIN school s on s.id = m.schoolid 
ORDER BY m.maskname ;

Note: You may have to change the function, as I don't know the complete table structure.

• Copy the content of backups folder into data folder. This worked for me.
• After this you have to reconfigure innodb files of your existent databases

As others have stated you need to check for null before invoking ToString but to avoid repeating yourself you could create an extension method that does that, something like:

public static class DateTimeExtensions {

  public static string ToStringOrDefault(this DateTime? source, string format, string defaultValue) {
    if (source != null) {
      return source.Value.ToString(format);
    }
    else {
      return String.IsNullOrEmpty(defaultValue) ?  String.Empty : defaultValue;
    }
  }

  public static string ToStringOrDefault(this DateTime? source, string format) {
       return ToStringOrDefault(source, format, null);
  }

}

Which can be invoked like:

DateTime? dt = DateTime.Now;
dt.ToStringOrDefault("yyyy-MM-dd hh:mm:ss");  
dt.ToStringOrDefault("yyyy-MM-dd hh:mm:ss", "n/a");
dt = null;
dt.ToStringOrDefault("yyyy-MM-dd hh:mm:ss", "n/a")  //outputs 'n/a'

The computer "name" is resolved from the IP address by the underlying DNS (Domain Name System) library of the OS. There's no universal concept of a computer name across OSes, but DNS is generally available. If the computer name hasn't been configured so DNS can resolve it, it isn't available.

import java.net.InetAddress;
import java.net.UnknownHostException;

String hostname = "Unknown";

try
{
    InetAddress addr;
    addr = InetAddress.getLocalHost();
    hostname = addr.getHostName();
}
catch (UnknownHostException ex)
{
    System.out.println("Hostname can not be resolved");
}

for those using git 2.x+ in powershell:

foreach ($filePath in (git ls-files --deleted)) { git add "$filePath" }

It happens since original orientation of image is not as we see in image viewer. In such cases image is displayed vertical to us in image viewer but it is horizontal in actual.

To resolve this do following:

1. Open image in image editor like paint ( in windows ) or ImageMagick ( in linux).

2. Rotate image left/right.

3. Save the image.

This should resolve the issue permanently.

use SELECT...INTO

The SELECT INTO statement creates a new table and populates it with the result set of the SELECT statement. SELECT INTO can be used to combine data from several tables or views into one table. It can also be used to create a new table that contains data selected from a linked server.

Example,

SELECT col1, col2 INTO #a -- <<== creates temporary table
FROM   tablename

• Inserting Rows by Using SELECT INTO

Standard Syntax,

SELECT  col1, ....., col@      -- <<== select as many columns as you want
        INTO [New tableName]
FROM    [Source Table Name]

Your object can also implement the Parcelable interface. Then you can use the Bundle.putParcelable() method and pass your object between activities within intent.

The Photostream application uses this approach and may be used as a reference.

As others have pointed out modulus is based on remainder system.

I think an easier way to think about modulus is what remains after a dividend (number to be divided) has been fully divided by a divisor. So if we think about 5%7, when you divide 5 by 7, 7 can go into 5 only 0 times and when you subtract 0 (7*0) from 5 (just like we learnt back in elementary school), then the remainder would be 5 ( the mod). See the illustration below.

   0
  ______
7) 5    
__-0____
   5

With the same logic, -5 mod 7 will be -5 ( only 0 7s can go in -5 and -5-0*7 = -5). With the same token -5 mod -7 will also be -5. A few more interesting cases:

5 mod (-3) = 2 i.e. 5 - (-3*-1)

(-5) mod (-3) = -2 i.e. -5 - (-3*1) = -5+3

Considering apply it to in loco or to a new immutable array, following other solutions, here is a suggested implementation:

Array.prototype.shuffle = function(local){
  var a = this;
  var newArray = typeof local === "boolean" && local ? this : [];
  for (var i = 0, newIdx, curr, next; i < a.length; i++){
    newIdx = Math.floor(Math.random()*i);
    curr = a[i];
    next = a[newIdx];
    newArray[i] = next;
    newArray[newIdx] = curr;
  }
  return newArray;
};

mylist[c(5,7,9)] should do it.

You want the sublists returned as sublists of the result list; you don't use [[]] (or rather, the function is [[) for that -- as Dason mentions in comments, [[ grabs the element.

The component solution and deep-clone solution have their advantages, but also have issues:

1. Sometimes you want to track changes in abstract data - it doesn't always make sense to build components around that data.

2. Deep-cloning your entire data structure every time you make a change can be very expensive.

I think there's a better way. If you want to watch all items in a list and know which item in the list changed, you can set up custom watchers on every item separately, like so:

var vm = new Vue({
  data: {
    list: [
      {name: 'obj1 to watch'},
      {name: 'obj2 to watch'},
    ],
  },
  methods: {
    handleChange (newVal) {
      // Handle changes here!
      console.log(newVal);
    },
  },
  created () {
    this.list.forEach((val) => {
      this.$watch(() => val, this.handleChange, {deep: true});
    });
  },
});

With this structure, handleChange() will receive the specific list item that changed - from there you can do any handling you like.

I have also documented a more complex scenario here, in case you are adding/removing items to your list (rather than only manipulating the items already there).

For ListView or GridView there is an another difference, when visibility initially set to

INVISIBLE:

Adapter's getView() function called

GONE:

Adapter's getView() function didn't call, thus preventing views to load, when it is unnecessary

Compared to window.location="url"; it is much easyer to do just location="url"; I always use that

From your other posts, I guess you want to learn a new language to get new skills. My advice is that the language is not really important, what is important is the quality of its community (advice, but also existing code you can read and learn from) and the available libraries/frameworks. In this respect, I think the "C family" is not the best choice for you: web libraries and frameworks are few, not portable and not great, and coding style of code you can study varies a lot and may confuse you a lot (although C is my favorite language).

I would advise to just learn C, and try to really understand the concept of pointers, then move to other languages more adapted to the web (Python or JavaScript comes to mind - or even Java). Also, in the C family, Objective-C has the best mix of power and simplicity in my opinion, but is a niche player.

It may be worth noting that auto-indent does not work if there are syntax errors in the document. Get rid of the red squigglies, and THEN try CTRL+K, CTRL+D, whatever...

Cron does not load the user's profile when running a task and you have to include the profile in your shell script explicitly.

Example documentation

This is actually possible to do with Object.create. It will not work for "non defined" properties. But for the ones that has been given a default value.

var defaults = {
    a: 'test1',
    b: 'test2'
};

Then when you create your properties object you do it with Object.create

properties = Object.create(defaults);

Now you will have two object where the first object is empty, but the prototype points to the defaults object. To test:

console.log('Unchanged', properties);
properties.a = 'updated';
console.log('Updated', properties);
console.log('Defaults', Object.getPrototypeOf(properties));

With using the inline-block it will behave as an inline object. so no floats needed to get them next to eachother on one line. And indeed as Rito said, floats need a "body", like they need dimensions.

I totally agree with Pekka about using tables. Everybody that build layouts using div's avoid tables like it's a desease. But use them for tablular data! That's what they're ment for. And in your case i think you need them :)

BUT if you really really want what you want. There is a css hack way. Same as the float hack.

.kundregister_grid_1:after {  content: ".";  }

Add that one and you're also set :D (Note: does not work in IE, but that is fixable)

I found the answer, you need to set the environment variable ANSIBLE_HOST_KEY_CHECKING to False. For example:

ANSIBLE_HOST_KEY_CHECKING=False ansible-playbook ...

I did this for a home folder where all the folders are on the desktops of the corresponding users, reachable through a shortcut which did not have the appropriate permissions, so that users couldn't see it even if it was there. So I used Robocopy with the parameter to overwrite the file with the right settings:

FOR /F "tokens=*" %G IN ('dir /b') DO robocopy  "\\server02\Folder with shortcut" "\\server02\home\%G\Desktop" /S /A /V /log+:C:\RobocopyShortcut.txt /XF *.url *.mp3 *.hta *.htm *.mht *.js *.IE5 *.css *.temp *.html *.svg *.ocx *.3gp *.opus *.zzzzz *.avi *.bin *.cab *.mp4 *.mov *.mkv *.flv *.tiff *.tif *.asf *.webm *.exe *.dll *.dl_ *.oc_ *.ex_ *.sy_ *.sys *.msi *.inf *.ini *.bmp *.png *.gif *.jpeg *.jpg *.mpg *.db *.wav *.wma *.wmv *.mpeg *.tmp *.old *.vbs *.log *.bat *.cmd *.zip /SEC /IT /ZB /R:0

As you see there are many file types which I set to ignore (just in case), just set them for your needs or your case scenario.

It was tested on Windows Server 2012, and every switch is documented on Microsoft's sites and others.

First up, this has got nothing to do with String, it is about arrays.. and that too specifically about declarative initialization of arrays.

As discussed by everyone in almost every answer here, you can, while declaring a variable, use:

String names[] = {"x","y","z"};

However, post declaration, if you want to assign an instance of an Array:

names = new String[] {"a","b","c"};

AFAIK, the declaration syntax is just a syntactic sugar and it is not applicable anymore when assigning values to variables because when values are assigned you need to create an instance properly.

However, if you ask us why it is so? Well... good luck getting an answer to that. Unless someone from the Java committee answers that or there is explicit documentation citing the said syntactic sugar.

You mean something like this?

<div class="image123">
    <div class="imgContainer">
        <img src="/images/tv.gif" height="200" width="200"/>
        <p>This is image 1</p>
    </div>
    <div class="imgContainer">
        <img class="middle-img" src="/images/tv.gif"/ height="200" width="200"/>
        <p>This is image 2</p>
    </div>
    <div class="imgContainer">
         <img src="/images/tv.gif"/ height="200" width="200"/>
        <p>This is image 3</p>
    </div>
</div>

with the imgContainer style as

.imgContainer{
    float:left;
}

Also see this jsfiddle.

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

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

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

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

To break it down:

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

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

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

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

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

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

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

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

You can use Take extension method

var array = new byte[] {1, 2, 3, 4};
var firstTwoItems = array.Take(2);

In my case, I had executed permissions and I couldn't run gradlew even with sudo. my problem was my project was in another hard drive and I didn't have exec permission on that drive. I simply removed noexec mount flag from fstab and added exec flag. then remount the disk so changes apply.

There are several issues:

1. Class names (and IDs) are not allowed to start with a digit.
2. You have to pass a class to getElementsByClassName().
3. You have to iterate of the result set.

Example (untested):

<script type="text/javascript">
function hideTd(className){
    var elements = document.getElementsByClassName(className);
    for(var i = 0, length = elements.length; i < length; i++) {
       if( elements[i].textContent == ''){
          elements[i].style.display = 'none';
       } 
    }

  }
</script>
</head>
<body onload="hideTd('td');">
<table border="1">
  <tr>
    <td class="td">not empty</td>
  </tr>
  <tr>
    <td class="td"></td>
  </tr>
  <tr>
    <td class="td"></td>
  </tr>
</table>
</body>

Note that getElementsByClassName() is not available up to and including IE8.

Update:

Alternatively you can give the table an ID and use:

var elements = document.getElementById('tableID').getElementsByTagName('td');

to get all td elements.

To hide the parent row, use the parentNode property of the element:

elements[i].parentNode.style.display = "none";

var variables still have a type - and the compiler error message says this type must be established during the declaration.

The specific request (assigning an initial null value) can be done, but I don't recommend it. It doesn't provide an advantage here (as the type must still be specified) and it could be viewed as making the code less readable:

var x = (String)null;

Which is still "type inferred" and equivalent to:

String x = null;

The compiler will not accept var x = null because it doesn't associate the null with any type - not even Object. Using the above approach, var x = (Object)null would "work" although it is of questionable usefulness.

Generally, when I can't use var's type inference correctly then

1. I am at a place where it's best to declare the variable explicitly; or
2. I should rewrite the code such that a valid value (with an established type) is assigned during the declaration.

The second approach can be done by moving code into methods or functions.

There is a library for this BarCode PHP. You just need to include a few files:

require_once('class/BCGFontFile.php');
require_once('class/BCGColor.php');
require_once('class/BCGDrawing.php');

You can generate many types of barcodes, namely 1D or 2D. Add the required library:

require_once('class/BCGcode39.barcode.php');

Generate the colours:

// The arguments are R, G, and B for color.
$colorFront = new BCGColor(0, 0, 0);
$colorBack = new BCGColor(255, 255, 255);

After you have added all the codes, you will get this way:

Example

Since several have asked for an example here is what I was able to do to get it done

require_once('class/BCGFontFile.php');
require_once('class/BCGColor.php');
require_once('class/BCGDrawing.php');

require_once('class/BCGcode128.barcode.php');

header('Content-Type: image/png');

$color_white = new BCGColor(255, 255, 255);

$code = new BCGcode128();
$code->parse('HELLO');

$drawing = new BCGDrawing('', $color_white);
$drawing->setBarcode($code);

$drawing->draw();
$drawing->finish(BCGDrawing::IMG_FORMAT_PNG);

If you want to actually create the image file so you can save it then change

$drawing = new BCGDrawing('', $color_white);

to

$drawing = new BCGDrawing('image.png', $color_white);

This is easy with a flexbox:

#wrapper {_x000D_
  display: flex;_x000D_
}_x000D_
_x000D_
#left {_x000D_
  flex: 0 0 65%;_x000D_
}_x000D_
_x000D_
#right {_x000D_
  flex: 1;_x000D_
}

<div id="wrapper">_x000D_
  <div id="left">Left side div</div>_x000D_
  <div id="right">Right side div</div>_x000D_
</div>

The httpd dæmon on OpenBSD uses the following stylesheet for all of its error messages, which presumably covers all the Comic Sans variations on non-Windows systems:

http://openbsd.su/src/usr.sbin/httpd/server_http.c#server_abort_http

810    style = "body { background-color: white; color: black; font-family: "
811        "'Comic Sans MS', 'Chalkboard SE', 'Comic Neue', sans-serif; }\n"
812        "hr { border: 0; border-bottom: 1px dashed; }\n";

E.g., try this:

font-family: 'Comic Sans MS', 'Chalkboard SE', 'Comic Neue', sans-serif;

"Once upon a time there were three little pigs".Split(" ") | ForEach {
    "$_ is a token"
 }

The key is $_, which stands for the current variable in the pipeline.

About the code you found online:

% is an alias for ForEach-Object. Anything enclosed inside the brackets is run once for each object it receives. In this case, it's only running once, because you're sending it a single string.

$_.Split(" ") is taking the current variable and splitting it on spaces. The current variable will be whatever is currently being looped over by ForEach.

ClassNotFoundException is a checked exception that occurs when we tell JVM to load a class by its string name using Class.forName() or ClassLoader.findSystemClass() or ClassLoader.loadClass() methods and mentioned class is not found in the classpath.

Most of the time, this exception occurs when you try to run an application without updating the classpath with required JAR files. For Example, You may have seen this exception when doing the JDBC code to connect to your database i.e.MySQL but your classpath does not have JAR for it.

NoClassDefFoundError error occurs when JVM tries to load a particular class that is the part of your code execution (as part of a normal method call or as part of creating an instance using the new keyword) and that class is not present in your classpath but was present at compile time because in order to execute your program you need to compile it and if you are trying use a class which is not present compiler will raise compilation error.

Below is the brief description

You can read Everything About ClassNotFoundException Vs NoClassDefFoundError for more details.
