According to official documentation https://keras.io/getting-started/faq/#how-can-i-install-hdf5-or-h5py-to-save-my-models-in-keras

you can do :

first test if you have h5py installed by running the

import h5py

if you dont have errors while importing h5py you are good to save:

from keras.models import load_model

model.save('my_model.h5')  # creates a HDF5 file 'my_model.h5'
del model  # deletes the existing model

# returns a compiled model
# identical to the previous one
model = load_model('my_model.h5')

If you need to install h5py http://docs.h5py.org/en/latest/build.html

Batch Normalization is used to normalize the input layer as well as hidden layers by adjusting mean and scaling of the activations. Because of this normalizing effect with additional layer in deep neural networks, the network can use higher learning rate without vanishing or exploding gradients. Furthermore, batch normalization regularizes the network such that it is easier to generalize, and it is thus unnecessary to use dropout to mitigate overfitting.

Right after calculating the linear function using say, the Dense() or Conv2D() in Keras, we use BatchNormalization() which calculates the linear function in a layer and then we add the non-linearity to the layer using Activation().

from keras.layers.normalization import BatchNormalization
model = Sequential()
model.add(Dense(64, input_dim=14, init='uniform'))
model.add(BatchNormalization(epsilon=1e-06, mode=0, momentum=0.9, weights=None))
model.add(Activation('tanh'))
model.add(Dropout(0.5))
model.add(Dense(64, init='uniform'))
model.add(BatchNormalization(epsilon=1e-06, mode=0, momentum=0.9, weights=None))
model.add(Activation('tanh'))
model.add(Dropout(0.5))
model.add(Dense(2, init='uniform'))
model.add(BatchNormalization(epsilon=1e-06, mode=0, momentum=0.9, weights=None))
model.add(Activation('softmax'))

sgd = SGD(lr=0.1, decay=1e-6, momentum=0.9, nesterov=True)
model.compile(loss='binary_crossentropy', optimizer=sgd)
model.fit(X_train, y_train, nb_epoch=20, batch_size=16, show_accuracy=True, 
validation_split=0.2, verbose = 2)

How is Batch Normalization applied?

Suppose we have input a[l-1] to a layer l. Also we have weights W[l] and bias unit b[l] for the layer l. Let a[l] be the activation vector calculated(i.e. after adding the non-linearity) for the layer l and z[l] be the vector before adding non-linearity

1. Using a[l-1] and W[l] we can calculate z[l] for the layer l
2. Usually in feed-forward propagation we will add bias unit to the z[l] at this stage like this z[l]+b[l], but in Batch Normalization this step of addition of b[l] is not required and no b[l] parameter is used.
3. Calculate z[l] means and subtract it from each element
4. Divide (z[l] - mean) using standard deviation. Call it Z_temp[l]

5. Now define new parameters ? and ß that will change the scale of the hidden layer as follows:

   z_norm[l] = ?.Z_temp[l] + ß

In this code excerpt, the Dense() takes the a[l-1], uses W[l] and calculates z[l]. Then the immediate BatchNormalization() will perform the above steps to give z_norm[l]. And then the immediate Activation() will calculate tanh(z_norm[l]) to give a[l] i.e.

a[l] = tanh(z_norm[l])

I let the CI server pipe the following into a file named CHANGELOG for a each new release with the date set in the release-filename:

>git log --graph --all --date=relative --pretty=format:"%x09 %ad %d %s (%aN)"

We create a validation set to

• Measure how well a model generalizes, during training
• Tell us when to stop training a model;When the validation loss stops decreasing (and especially when the validation loss starts increasing and the training loss is still decreasing)

Why validation set used:

I've recently used both Raphael and jQuery SVG - and here are my thoughts:

Raphael

Pros: a good starter library, easy to do a LOT of things with SVG quickly. Well written and documented. Lots of examples and Demos. Very extensible architecture. Great with animation.

Cons: is a layer over the actual SVG markup, makes it difficult to do more complex things with SVG - such as grouping (it supports Sets, but not groups). Doesn't do great w/ editing of already existing elements.

jQuery SVG

Pros: a jquery plugin, if you're already using jQuery. Well written and documented. Lots of examples and demos. Supports most SVG elements, allows native access to elements easily

Cons: architecture not as extensible as Raphael. Some things could be better documented (like configure of SVG element). Doesn't do great w/ editing of already existing elements. Relies on SVG semantics for animation - which is not that great.

SnapSVG as a pure SVG version of Raphael

SnapSVG is the successor of Raphael. It is supported only in the SVG enabled browsers and supports almost all the features of SVG.

Conclusion

If you're doing something quick and easy, Raphael is an easy choice. If you're going to do something more complex, I chose to use jQuery SVG because I can manipulate the actual markup significantly easier than with Raphael. And if you want a non-jQuery solution then SnapSVG is a good option.

To detect whether two balls collide, just check whether the distance between their centers is less than two times the radius. To do a perfectly elastic collision between the balls, you only need to worry about the component of the velocity that is in the direction of the collision. The other component (tangent to the collision) will stay the same for both balls. You can get the collision components by creating a unit vector pointing in the direction from one ball to the other, then taking the dot product with the velocity vectors of the balls. You can then plug these components into a 1D perfectly elastic collision equation.

Wikipedia has a pretty good summary of the whole process. For balls of any mass, the new velocities can be calculated using the equations (where v1 and v2 are the velocities after the collision, and u1, u2 are from before):

If the balls have the same mass then the velocities are simply switched. Here's some code I wrote which does something similar:

void Simulation::collide(Storage::Iterator a, Storage::Iterator b)
{
    // Check whether there actually was a collision
    if (a == b)
        return;

    Vector collision = a.position() - b.position();
    double distance = collision.length();
    if (distance == 0.0) {              // hack to avoid div by zero
        collision = Vector(1.0, 0.0);
        distance = 1.0;
    }
    if (distance > 1.0)
        return;

    // Get the components of the velocity vectors which are parallel to the collision.
    // The perpendicular component remains the same for both fish
    collision = collision / distance;
    double aci = a.velocity().dot(collision);
    double bci = b.velocity().dot(collision);

    // Solve for the new velocities using the 1-dimensional elastic collision equations.
    // Turns out it's really simple when the masses are the same.
    double acf = bci;
    double bcf = aci;

    // Replace the collision velocity components with the new ones
    a.velocity() += (acf - aci) * collision;
    b.velocity() += (bcf - bci) * collision;
}

As for efficiency, Ryan Fox is right, you should consider dividing up the region into sections, then doing collision detection within each section. Keep in mind that balls can collide with other balls on the boundaries of a section, so this may make your code much more complicated. Efficiency probably won't matter until you have several hundred balls though. For bonus points, you can run each section on a different core, or split up the processing of collisions within each section.

I wouldn't go with MSTest. Although it's probably the most future proof of the frameworks with Microsoft behind it's not the most flexible solution. It won't run stand alone without some hacks. So running it on a build server other than TFS without installing Visual Studio is hard. The visual studio test-runner is actually slower than Testdriven.Net + any of the other frameworks. And because the releases of this framework are tied to releases of Visual Studio there are less updates and if you have to work with an older VS you're tied to an older MSTest.

I don't think it matters a lot which of the other frameworks you use. It's really easy to switch from one to another.

I personally use XUnit.Net or NUnit depending on the preference of my coworkers. NUnit is the most standard. XUnit.Net is the leanest framework.

If you are looking for performance and using std::vector, I recommend the one that this documentation link provides.

std::vector<int> myvector{10,20,20,20,30,30,20,20,10};             // 10 20 20 20 30 30 20 20 10
std::sort(myvector.begin(), myvector.end() );
const auto& it = std::unique (myvector.begin(), myvector.end());   // 10 20 30 ?  ?  ?  ?  ?  ?
                                                                   //          ^
myvector.resize( std::distance(myvector.begin(),it) ); // 10 20 30

In config.php add or edit the following lines to this:
------------------------------------------------------
$config['log_threshold'] = 4; // (1/2/3)
$config['log_path'] = '/home/path/to/application/logs/';

Run this command in the terminal:
----------------------------------
sudo chmod -R 777 /home/path/to/application/logs/

I think that if you have a to, you must use a from. I would think of something like :

@keyframe in {
    from: transform: rotate(0deg);
    to: transform: rotate(360deg);
}

@keyframe out {
    from: transform: rotate(360deg);
    to: transform: rotate(0deg);
}

Of course must have checked it already, but I found strange that you only use the transform property since CSS3 is not fully implemented everywhere. Maybe it would work better with the following considerations :

• Chrome uses @-webkit-keyframes, no particuliar version needed
• Safari uses @-webkit-keyframes since version 5+
• Firefox uses @keyframes since version 16 (v5-15 used @-moz-keyframes)
• Opera uses @-webkit-keyframes version 15-22 (only v12 used @-o-keyframes)
• Internet Explorer uses @keyframes since version 10+

EDIT :

I came up with that fiddle :

http://jsfiddle.net/JjHNG/35/

Using minimal code. Is it approaching what you were expecting ?

I have JSONObject like this: {"status":[{"Response":"success"}]}.

If I want to convert the JSONObject value, which is a JSONArray into JSONObject automatically without using any static value, here is the code for that.

JSONArray array=new JSONArray();
JSONObject obj2=new JSONObject();
obj2.put("Response", "success");
array.put(obj2);
JSONObject obj=new JSONObject();
obj.put("status",array);

Converting the JSONArray to JSON Object:

Iterator<String> it=obj.keys();
        while(it.hasNext()){
String keys=it.next();
JSONObject innerJson=new JSONObject(obj.toString());
JSONArray innerArray=innerJson.getJSONArray(keys);
for(int i=0;i<innerArray.length();i++){
JSONObject innInnerObj=innerArray.getJSONObject(i);
Iterator<String> InnerIterator=innInnerObj.keys();
while(InnerIterator.hasNext()){
System.out.println("InnInnerObject value is :"+innInnerObj.get(InnerIterator.next()));


 }
}

Resolved the problem using Jackson library. Prints are called out of Main class and all POJO classes are created. Here is the code snippets.

MainClass.java

public class MainClass {
  public static void main(String[] args) throws JsonParseException, 
       JsonMappingException, IOException {

String jsonStr = "{\r\n" + "    \"id\": 2,\r\n" + " \"socket\": \"0c317829-69bf- 
             43d6-b598-7c0c550635bb\",\r\n"
            + " \"type\": \"getDashboard\",\r\n" + "    \"data\": {\r\n"
            + "     \"workstationUuid\": \"ddec1caa-a97f-4922-833f- 
            632da07ffc11\"\r\n" + " },\r\n"
            + " \"reply\": true\r\n" + "}";

    ObjectMapper mapper = new ObjectMapper();

    MyPojo details = mapper.readValue(jsonStr, MyPojo.class);

    System.out.println("Value for getFirstName is: " + details.getId());
    System.out.println("Value for getLastName  is: " + details.getSocket());
    System.out.println("Value for getChildren is: " + 
      details.getData().getWorkstationUuid());
    System.out.println("Value for getChildren is: " + details.getReply());

}

MyPojo.java

public class MyPojo {
    private String id;

    private Data data;

    private String reply;

    private String socket;

    private String type;

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public Data getData() {
        return data;
    }

    public void setData(Data data) {
        this.data = data;
    }

    public String getReply() {
        return reply;
    }

    public void setReply(String reply) {
        this.reply = reply;
    }

    public String getSocket() {
        return socket;
    }

    public void setSocket(String socket) {
        this.socket = socket;
    }

    public String getType() {
        return type;
    }

    public void setType(String type) {
        this.type = type;
    } 
}

Data.java

public class Data {
    private String workstationUuid;

    public String getWorkstationUuid() {
        return workstationUuid;
    }

    public void setWorkstationUuid(String workstationUuid) {
        this.workstationUuid = workstationUuid;
    }   
}

RESULTS:

Value for getFirstName is: 2
Value for getLastName  is: 0c317829-69bf-43d6-b598-7c0c550635bb
Value for getChildren is: ddec1caa-a97f-4922-833f-632da07ffc11
Value for getChildren is: true

use labelpad parameter:

pl.xlabel("...", labelpad=20)

or set it after:

ax.xaxis.labelpad = 20

I have found this simple javascript snippet very useful.

$(document).ready(function()
{
    var navbar = $('#navbar');

    navbar.after('<div id="more-div" style="height: ' + navbar.outerHeight(true) + 'px" class="hidden"></div>');
    var afternavbar = $('#more-div');

    var abovenavbar = $('#above-navbar');

    $(window).on('scroll', function()
    {
        if ($(window).scrollTop() > abovenavbar.height())
        {
            navbar.addClass('navbar-fixed-top');
            afternavbar.removeClass('hidden');
        }
        else
        {
            navbar.removeClass('navbar-fixed-top');
            afternavbar.addClass('hidden');
        }
    });
});

Try this configuration:

    position to absolute
    width to 100%
    height to 100px
    bottom to 10
    background-color: blue

This can help actually move the div to the bottom. Just modify accordingly.

It's because you have a recursive function inside of rotate. It's calling itself again:

// Animate rotation with a recursive call
setTimeout(function() { rotate(++degree); },65);

Take that out and it won't keep on running recursively.

I would also suggest just using this function instead:

function rotate($el, degrees) {
    $el.css({
  '-webkit-transform' : 'rotate('+degrees+'deg)',
     '-moz-transform' : 'rotate('+degrees+'deg)',  
      '-ms-transform' : 'rotate('+degrees+'deg)',  
       '-o-transform' : 'rotate('+degrees+'deg)',  
          'transform' : 'rotate('+degrees+'deg)',  
               'zoom' : 1

    });
}

It's much cleaner and will work for the most amount of browsers.

If sounds like the type ACTInterface is not public, but is using the default accessibility of either internal (if it is top-level) or private (if it is nested in another type).

Giving the type the public modifier would fix it.

Another approach is to make both the type and the method internal, if that is your intent.

The issue is not the accessibility of the field (oActInterface), but rather of the type ACTInterface itself.

What you actually created with:

MyType[] list = []

Was fixed size array (not list) with size of 0. You can create fixed size array of size for example 4 with:

MyType[] array = new MyType[4]

But there's no add method of course.

If you create list with def it's something like creating this instance with Object (You can read more about def here). And [] creates empty ArrayList in this case.

So using def list = [] you can then append new items with add() method of ArrayList

list.add(new MyType())

Or more groovy way with overloaded left shift operator:

list << new MyType() 

You can try this for get current month first day;

DateTime.Now.AddDays(-(DateTime.Now.Day-1))

and assign it a value.

Like this:

dateEndEdit.EditValue = DateTime.Now;
dateStartEdit.EditValue = DateTime.Now.AddDays(-(DateTime.Now.Day-1));

No longer works for spreadsheets Protected with Excel 2013 or later -- they improved the pw hash. So now need to unzip .xlsx and hack the internals.

From Java SE 6 HotSpot[tm] Virtual Machine Garbage Collection Tuning

the following

Excessive GC Time and OutOfMemoryError

The concurrent collector will throw an OutOfMemoryError if too much time is being spent in garbage collection: if more than 98% of the total time is spent in garbage collection and less than 2% of the heap is recovered, an OutOfMemoryError will be thrown. This feature is designed to prevent applications from running for an extended period of time while making little or no progress because the heap is too small. If necessary, this feature can be disabled by adding the option -XX:-UseGCOverheadLimit to the command line.

The policy is the same as that in the parallel collector, except that time spent performing concurrent collections is not counted toward the 98% time limit. In other words, only collections performed while the application is stopped count toward excessive GC time. Such collections are typically due to a concurrent mode failure or an explicit collection request (e.g., a call to System.gc()).

in conjunction with a passage further down

One of the most commonly encountered uses of explicit garbage collection occurs with RMIs distributed garbage collection (DGC). Applications using RMI refer to objects in other virtual machines. Garbage cannot be collected in these distributed applications without occasionally collection the local heap, so RMI forces full collections periodically. The frequency of these collections can be controlled with properties. For example,

java -Dsun.rmi.dgc.client.gcInterval=3600000

-Dsun.rmi.dgc.server.gcInterval=3600000 specifies explicit collection once per hour instead of the default rate of once per minute. However, this may also cause some objects to take much longer to be reclaimed. These properties can be set as high as Long.MAX_VALUE to make the time between explicit collections effectively infinite, if there is no desire for an upper bound on the timeliness of DGC activity.

Seems to imply that the evaluation period for determining the 98% is one minute long, but it might be configurable on Sun's JVM with the correct define.

Of course, other interpretations are possible.

For people who want to use another diff tool not listed in git, say with nvim. here is what I ended up using:

git config --global alias.d difftool -x <tool name>

In my case, I set <tool name> to nvim -d and invoke the diff command with

git d <file>

I did this;

In controller:

public ActionResult Index()
{
  var invoices = db.Invoices;

  var categories = db.Categories.ToList();
  ViewData["MyData"] = categories; // Send this list to the view

  return View(invoices.ToList());
}

In view:

@model IEnumerable<abc.Models.Invoice>

@{
    ViewBag.Title = "Invoices";
}

@{
  var categories = (List<Category>) ViewData["MyData"]; // Cast the list
}

@foreach (var c in @categories) // Print the list
{
  @Html.Label(c.Name);
}

<table>
    ...
    @foreach (var item in Model) 
    {
      ...
    }
</table>

Hope it helps

To set the status bar color, create a style.xml file under res/values-v21 folder with this content:

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <style name="AppBaseTheme" parent="AppTheme">
        <item name="android:windowDrawsSystemBarBackgrounds">true</item>
        <item name="android:statusBarColor">@color/blue</item>
    </style>

</resources>

What is “export default” in JavaScript?

In default export the naming of import is completely independent and we can use any name we like.

I will illustrate this line with a simple example.

Let’s say we have three modules and an index.html file:

• modul.js
• modul2.js
• modul3.js
• index.html

File modul.js

export function hello() {
    console.log("Modul: Saying hello!");
}

export let variable = 123;

File modul2.js

export function hello2() {
    console.log("Module2: Saying hello for the second time!");
}

export let variable2 = 456;

modul3.js

export default function hello3() {
    console.log("Module3: Saying hello for the third time!");
}

File index.html

<script type="module">
import * as mod from './modul.js';
import {hello2, variable2} from './modul2.js';
import blabla from './modul3.js'; // ! Here is the important stuff - we name the variable for the module as we like

mod.hello();
console.log("Module: " + mod.variable);

hello2();
console.log("Module2: " + variable2);

blabla();
</script>

The output is:

modul.js:2:10   -> Modul: Saying hello!
index.html:7:9  -> Module: 123
modul2.js:2:10  -> Module2: Saying hello for the second time!
index.html:10:9 -> Module2: 456
modul3.js:2:10  -> Module3: Saying hello for the third time!

So the longer explanation is:

'export default' is used if you want to export a single thing for a module.

So the thing that is important is "import blabla from './modul3.js'" - we could say instead:

"import pamelanderson from './modul3.js" and then pamelanderson();. This will work just fine when we use 'export default' and basically this is it - it allows us to name it whatever we like when it is default.

P.S.: If you want to test the example - create the files first, and then allow CORS in the browser -> if you are using Firefox type in the URL of the browser: about:config -> Search for "privacy.file_unique_origin" -> change it to "false" -> open index.html -> press F12 to open the console and see the output -> Enjoy and don't forget to return the CORS settings to default.

P.S.2: Sorry for the silly variable naming

More information is in link2medium and link2mdn.

Want to put out there that there is not much to worry about if someone provides an answer as an extension method because an extension method is just a cool way to call an instance method. I understand that you want the answer without using an extension method. Regardless if the method is defined as static, instance or extension - the result is the same.

The code below uses the code from the accepted answer to define an extension method and an instance method and creates a unit test to show the output is the same.

public static class Extensions
{
    public static void Each<T>(this IEnumerable<T> items, Action<T> action)
    {
        foreach (var item in items)
        {
            action(item);
        }
    }
}

[TestFixture]
public class ForEachTests
{
    public void Each<T>(IEnumerable<T> items, Action<T> action)
    {
        foreach (var item in items)
        {
            action(item);
        }
    }

    private string _extensionOutput;

    private void SaveExtensionOutput(string value)
    {
        _extensionOutput += value;
    }

    private string _instanceOutput;

    private void SaveInstanceOutput(string value)
    {
        _instanceOutput += value;
    }

    [Test]
    public void Test1()
    {
        string[] teams = new string[] {"cowboys", "falcons", "browns", "chargers", "rams", "seahawks", "lions", "heat", "blackhawks", "penguins", "pirates"};

        Each(teams, SaveInstanceOutput);

        teams.Each(SaveExtensionOutput);

        Assert.AreEqual(_extensionOutput, _instanceOutput);
    }
}

Quite literally, the only thing you need to do to convert an extension method to an instance method is remove the static modifier and the first parameter of the method.

This method

public static void Each<T>(this IEnumerable<T> items, Action<T> action)
{
    foreach (var item in items)
    {
        action(item);
    }
 }

becomes

public void Each<T>(Action<T> action)
{
    foreach (var item in items)
    {
        action(item);
    }
 }

If you want to overwrite any css in bootstrap use !important

Let's say here is the page header class in bootstrap which have 40px margin on top, my client don't like it and he want it to be 15 on top and 10 on bottom only

.page-header {
    border-bottom: 1px solid #EEEEEE;
    margin: 40px 0 20px;
    padding-bottom: 9px;
}

So I added on class in my site.css file with the same name like this

.page-header
{
    padding-bottom: 9px;
    margin: 15px 0 10px 0px !important;
}

Note the !important with my margin, which will overwrite the margin of bootstarp page-header class margin.

If you really just want to subset each data frame by an index that exists in both data frames, you can do this with the 'match' function, like so:

data_A[match(data_B$index, data_A$index, nomatch=0),]
data_B[match(data_A$index, data_B$index, nomatch=0),]

This is, though, the same as:

data_A[data_A$index %in% data_B$index,]
data_B[data_B$index %in% data_A$index,]

Here is a demo:

# Set seed for reproducibility.
set.seed(1)

# Create two sample data sets.
data_A <- data.frame(index=sample(1:200, 90, rep=FALSE), value=runif(90))

I built my solution on top of @aditya Prakash appraoch:

 print(re.search("^([1-9]|0[1-9]|1[0-9]|2[0-9]|3[0-1])(\.|-|/)([1-9]|0[1-9]|1[0-2])(\.|-|/)([0-9][0-9]|19[0-9][0-9]|20[0-9][0-9])$|^([0-9][0-9]|19[0-9][0-9]|20[0-9][0-9])(\.|-|/)([1-9]|0[1-9]|1[0-2])(\.|-|/)([1-9]|0[1-9]|1[0-9]|2[0-9]|3[0-1])$",'01/01/2018'))

The first part (^([1-9]|0[1-9]|1[0-9]|2[0-9]|3[0-1])(\.|-|/)([1-9]|0[1-9]|1[0-2])(\.|-|/)([0-9][0-9]|19[0-9][0-9]|20[0-9][0-9])$) can handle the following formats:

• 01.10.2019
• 1.1.2019
• 1.1.19
• 12/03/2020
• 01.05.1950

The second part (^([0-9][0-9]|19[0-9][0-9]|20[0-9][0-9])(\.|-|/)([1-9]|0[1-9]|1[0-2])(\.|-|/)([1-9]|0[1-9]|1[0-9]|2[0-9]|3[0-1])$) can basically do the same, but in inverse order, where the year comes first, followed by month, and then day.

• 2020/02/12

As delimiters it allows ., /, -. As years it allows everything from 1900-2099, also giving only two numbers is fine.

If you have suggestions for improvement please let me know in the comments, so I can update the answer.

The api is fairly easy to use.

// Lookup the dns, if the ip exists.
 if (!ip.isEmpty()) {
     InetAddress inetAddress = InetAddress.getByName(ip);
     dns = inetAddress.getCanonicalHostName(); 
 }

It is not clear why you want to do this. If you want to get the correct numerical value, you could use unary + ^[docs]:

value = +value;

If you just want to format the text, then regex could be better. It depends on the values you are dealing with I'd say. If you only have integers, then

input.value = +input.value;

is fine as well. Of course it also works for float values, but depending on how many digits you have after the point, converting it to a number and back to a string could (at least for displaying) remove some.

Short answer No. CSS is not specific to brands.

Below are the articles to implement for iOS using media only.

https://css-tricks.com/snippets/css/media-queries-for-standard-devices/

http://stephen.io/mediaqueries/

Infact you can use PHP, Javascript to detect the iOS browser and according to that you can call CSS file. For instance

Bootstrap modal show event

$('#modal-content').on('show.bs.modal', function() {

In Windows, I solved this problem editing directly the file /bin/cassandra.bat, changing the value of the "Xms" and "Xmx" JVM_OPTS parameters. You can try to edit the /bin/cassandra file. In this file I see an commented variable JVM_OPTS, try to uncomment and edit it.

Important notice: the property (part of hibernate configuration, NOT part of logging framework config!)

hibernate.show_sql

controls the logging directly to STDOUT bypassing any logging framework (which you can recognize by the missing output formatting of the messages). If you use a logging framework like log4j, you should always set that property to false because it gives you no benefit at all.

That circumstance irritated me quite a long time because I never really cared about it until I tried to write some benchmark regarding Hibernate.

This is a way to copy plugins from one Jenkins box to another.

Copy over the plugins directory:

scp -r jenkins-box.url.com:/var/lib/jenkins/plugins .

Compress the plugins:

tar cvfJ plugins.tar.xz plugins

Copy them over to the other Jenkins box:

scp plugins.tar.xz different-jenkins-box.url.com
ssh different-jenkins-box.url.com "tar xvfJ plugins.tar.xz -C /var/lib/jenkins"

Restart Jenkins.

An enum is just another class in Java, it should be possible.

More accurately, an enum is an instance of Object: http://docs.oracle.com/javase/6/docs/api/java/lang/Enum.html

So yes, it should work.

Here is how its done in Angular 6

<li *ngFor="let user of userObservable ; first as isFirst">
   <span *ngIf="isFirst">default</span>
</li>

Note the change from let first = first to first as isFirst

Or you could just put

background-color: rgba(0,0,0,0.0);

That should solve your problem.

Multiple column ordering depends on both column's corresponding values: Here is my table example where are two columns named with Alphabets and Numbers and the values in these two columns are asc and desc orders.

Now I perform Order By in these two columns by executing below command:

Now again I insert new values in these two columns, where Alphabet value in ASC order:

and the columns in Example table look like this. Now again perform the same operation:

You can see the values in the first column are in desc order but second column is not in ASC order.

The most basic way you can do this in SelectedIndexChanged events of DropDownLists. Check this code..

    <asp:DropDownList ID="DropDownList1" runat="server" onselectedindexchanged="DropDownList1_SelectedIndexChanged" Width="224px"
        AutoPostBack="True" AppendDataBoundItems="true">
    <asp:DropDownList ID="DropDownList2" runat="server"
        onselectedindexchanged="DropDownList2_SelectedIndexChanged">
    </asp:DropDownList> 


protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
    //Load DropDownList2

}
protected void DropDownList2_SelectedIndexChanged(object sender, EventArgs e)
{
    //Load DropDownList3
}

long is equivalent to long int, just as short is equivalent to short int. A long int is a signed integral type that is at least 32 bits, while a long long or long long int is a signed integral type is at least 64 bits.

This doesn't necessarily mean that a long long is wider than a long. Many platforms / ABIs use the LP64 model - where long (and pointers) are 64 bits wide. Win64 uses the LLP64, where long is still 32 bits, and long long (and pointers) are 64 bits wide.

There's a good summary of 64-bit data models here.

long double doesn't guarantee much other than it will be at least as wide as a double.

A lot of the comments answer most of your questions, but I mainly wanted to contribute to this question:

Is there a way in which the behavior of the backtick actually differs from that of a single quote?

A difference I've noticed for template strings is the disability to set one as an object property. More information in this post; an interesting quote from the accepted answer:

Template strings are expressions, not literals1.

But basically, if you ever wanted to use it as an object property you'd have to use it wrapped with square brackets.

// Throws error
const object = {`templateString`: true};

// Works
const object = {[`templateString`]: true};

Try This:

In strings.xml add your title and subtitle...

ActionBar ab = getActionBar();
ab.setTitle(getResources().getString(R.string.myTitle));
ab.setSubtitle(getResources().getString(R.string.mySubTitle));

var numbers = [1, 2, 7, 5];    
var val = sort(numbers){$0 > $1}[0];

The answers at the other link will work, but to serve out HTML, there is no need to use a view engine at all, unless you want to set up funky routing. Instead, just use the static middleware:

app.use(express.static(__dirname + '/public'));

It looks like from the Java docs here that add returns a new BigDecimal:

BigDecimal test = new BigDecimal(0);
System.out.println(test);
test = test.add(new BigDecimal(30));
System.out.println(test);
test = test.add(new BigDecimal(45));
System.out.println(test);

JonH has covered very well the part on how to write the query. There is another significant issue that must be mentioned too, however, which is the performance characteristics of such a query. Let's repeat it here (adapted to Oracle):

SELECT EmployeeName FROM EmployeeTable WHERE LENGTH(EmployeeName) > 4;

This query is restricting the result of a function applied to a column value (the result of applying the LENGTH function to the EmployeeName column). In Oracle, and probably in all other RDBMSs, this means that a regular index on EmployeeName will be useless to answer this query; the database will do a full table scan, which can be really costly.

However, various databases offer a function indexes feature that is designed to speed up queries like this. For example, in Oracle, you can create an index like this:

CREATE INDEX EmployeeTable_EmployeeName_Length ON EmployeeTable(LENGTH(EmployeeName));

This might still not help in your case, however, because the index might not be very selective for your condition. By this I mean the following: you're asking for rows where the name's length is more than 4. Let's assume that 80% of the employee names in that table are longer than 4. Well, then the database is likely going to conclude (correctly) that it's not worth using the index, because it's probably going to have to read most of the blocks in the table anyway.

However, if you changed the query to say LENGTH(EmployeeName) <= 4, or LENGTH(EmployeeName) > 35, assuming that very few employees have names with fewer than 5 character or more than 35, then the index would get picked and improve performance.

Anyway, in short: beware of the performance characteristics of queries like the one you're trying to write.

For me it must have:

mongod --dbpath=/whatever/data/path

Yes, you can delete data from iOS device support by the symbols of the operating system, one for each version for each architecture. It's used for debugging. If you don't need to support those devices any more, you can delete the directory without ill effect

Starting with MongoDB v3.4 (released in 2016), the $lookup aggregation pipeline stage can also work directly with an array. There is no need for $unwind any more.

This was tracked in SERVER-22881.

You should use tabIndex attribute to be able to listen onKeyDown event on a div in React. Setting tabIndex="0" should fire your handler.

First point is- showing multiple popups is not desirable in terms of usability.

But you can achieve it by using multiple popup names

var newwindow;
function createPop(url, name)
{    
   newwindow=window.open(url,name,'width=560,height=340,toolbar=0,menubar=0,location=0');  
   if (window.focus) {newwindow.focus()}
}

Better approach will be showing both in a single page in two different iFrames or Divs.

Update:

So I will suggest to create a new tab in the test.aspx page to show the report, instead of replacing the image content and placing the pdf.

All we need:

1. Wrap a constant in a function (where the name of the function equals the name of the object we want to get)
2. Use arrow functions inside the object

console.clear();_x000D_
function App(){ // name of my constant is App_x000D_
  return {_x000D_
  a: {_x000D_
    b: {_x000D_
      c: ()=>{ // very important here, use arrow function _x000D_
        console.log(this.constructor.name)_x000D_
      }_x000D_
    }_x000D_
  }_x000D_
}_x000D_
}_x000D_
const obj = new App(); // usage_x000D_
_x000D_
obj.a.b.c(); // App_x000D_
_x000D_
// usage with react props etc, _x000D_

1. Install Style Loader and CSS Loader:

   npm install --save-dev style-loader
   npm install --save-dev css-loader
   

2. Configure webpack

   module: {
           loaders: [
               {
                   test: /\.css$/,
                   loader: 'style-loader'
               }, {
                   test: /\.css$/,
                   loader: 'css-loader',
                   query: {
                       modules: true,
                       localIdentName: '[name]__[local]___[hash:base64:5]'
                   }
               }
           ]
       }
   

This is quite simple to do and the answer is available in other queries. For those of you who are viewing this:

select entries from my_entries where id='42' INTO OUTFILE 'bishwas.txt';

Hold down Ctrl+Shift+P (or cmd on Mac), select "Change Language Mode" and there it is.

But I still can't find a way to make VS Code recognized files with specific extension as some certain language.

I had to add a Return-Path header in emails send by a Redmine instance. I agree with greatwolf only the sender can determine a correct (non default) Return-Path. The case is the following : E-mails are send with the default email address : [email protected] But we want that the real user initiating the action receives the bounce emails, because he will be the one knowing how to fix wrong recipients emails (and not the application adminstrators that have other cats to whip :-) ). We use this and it works perfectly well with exim on the application server and zimbra as the final company mail server.

What is your output when you do java -version? This will tell you what version the running JVM is.

The Unsupported major.minor version 51.0 error could mean:

• Your server is running a lower Java version then the one used to compile your Servlet and vice versa

Either way, uninstall all JVM runtimes including JDK and download latest and re-install. That should fix any Unsupported major.minor error as you will have the lastest JRE and JDK (Maybe even newer then the one used to compile the Servlet)

See: http://www.java.com/en/download/manual.jsp (7 Update 25 )

and here: http://www.oracle.com/technetwork/java/javase/downloads/index.html (Java Platform (JDK) 7u25)

for the latest version of the JRE and JDK respectively.

EDIT:

Most likely your code was written in Java7 however maybe it was done using Java7update4 and your system is running Java7update3. Thus they both are effectively the same major version but the minor versions differ. Only the larger minor version is backward compatible with the lower minor version.

Edit 2 : If you have more than one jdk installed on your pc. you should check that Apache Tomcat is using the same one (jre) you are compiling your programs with. If you installed a new jdk after installing apache it normally won't select the new version.

I also encuntered the same in S4. I've tested the app in Galaxy Grand , HTC , Sony Experia but got only in s4. You can ignore it as its not related to your app.

Because there are two print statements. First is inside function and second is outside function. When function not return any thing that time it return None value.

Use return statement at end of function to return value.

e.g.:

Return None value.

>>> def test1():
...    print "In function."
... 
>>> a = test1()
In function.
>>> print a
None
>>> 
>>> print test1()
In function.
None
>>>
>>> test1()
In function.
>>> 

Use return statement

>>> def test():
...   return "ACV"
... 
>>> print test()
ACV
>>> 
>>> a = test()
>>> print a
ACV
>>> 

I use the following PowerShell snippet to get CPU usage for local or remote systems:

Get-Counter -ComputerName localhost '\Process(*)\% Processor Time' | Select-Object -ExpandProperty countersamples | Select-Object -Property instancename, cookedvalue| Sort-Object -Property cookedvalue -Descending| Select-Object -First 20| ft InstanceName,@{L='CPU';E={($_.Cookedvalue/100).toString('P')}} -AutoSize

Same script but formatted with line continuation:

Get-Counter -ComputerName localhost '\Process(*)\% Processor Time' `
    | Select-Object -ExpandProperty countersamples `
    | Select-Object -Property instancename, cookedvalue `
    | Sort-Object -Property cookedvalue -Descending | Select-Object -First 20 `
    | ft InstanceName,@{L='CPU';E={($_.Cookedvalue/100).toString('P')}} -AutoSize

On a 4 core system it will return results that look like this:

InstanceName          CPU

The ComputerName argument will accept a list of servers, so with a bit of extra formatting you can generate a list of top processes on each server. Something like:

$psstats = Get-Counter -ComputerName utdev1,utdev2,utdev3 '\Process(*)\% Processor Time' -ErrorAction SilentlyContinue | Select-Object -ExpandProperty countersamples | %{New-Object PSObject -Property @{ComputerName=$_.Path.Split('\')[2];Process=$_.instancename;CPUPct=("{0,4:N0}%" -f $_.Cookedvalue);CookedValue=$_.CookedValue}} | ?{$_.CookedValue -gt 0}| Sort-Object @{E='ComputerName'; A=$true },@{E='CookedValue'; D=$true },@{E='Process'; A=$true }
$psstats | ft @{E={"{0,25}" -f $_.Process};L="ProcessName"},CPUPct -AutoSize -GroupBy ComputerName -HideTableHeaders

Just use

get_metadata( 'post', 15 );

You can easily share any desired location from the macOS Maps application to the Xcode simulator.

1. From Xcode run the application in the simulator as you usually do.
2. Open the maps application on macOS (for convenience I usually make a new Desktop where I have both the simulator and the map application).
3. Inside the maps (macOS), long click on any point on the map, or search for a place to let the map draw a pin where you need it.
4. Click on the pin, then on the information (i) icon (see image).
5. In the up right of the information view click on the share icon.
6. Share the location with the simulator (see image).
7. Confirm and enjoy :)

This let you test some locations quickly, having an understanding on where geographically the location is (e.g. for testing geofencing), and deciding at runtime where to go next (e.g. for debugging and fine-tuning stuff).

Tested this on MacOS Catalina 10.15.4 and Xcode 11.4.

Use hidden.

<select>_x000D_
   <option hidden>Choose</option>_x000D_
   <option>Item 1</option>_x000D_
   <option>Item 2</option>_x000D_
</select>

This doesn't unset it but you can however hide it in the options while it's displayed by default.

A thread safe rotation function is the following (it works much better):

        transform = CGAffineTransformRotate(transform, M_PI / 2.0);
        break;

    case UIImageOrientationRight: //EXIF = 8

Check if you are implementing the code inside a could drive like box, dropbox etc. If you copy the files you are trying to implement to a local folder on your machine you should be able to get rid of the error.

$str = "http://www.vimeo.com/1234567";
$s = explode("/",$str);
print end($s);

You could also use:

is_array($_POST)

You can use a dynamic array when you don't know the number of values it will contain until run-time:

Dim Zombies() As Integer
ReDim Zombies(NumberOfZombies)

Or you could do everything with one statement if you're creating an array that's local to a procedure:

ReDim Zombies(NumberOfZombies) As Integer

Fixed-size arrays require the number of elements contained to be known at compile-time. This is why you can't use a variable to set the size of the array—by definition, the values of a variable are variable and only known at run-time.

You could use a constant if you knew the value of the variable was not going to change:

Const NumberOfZombies = 2000

but there's no way to cast between constants and variables. They have distinctly different meanings.

You can get the maximum like this:

>>> import pandas as pd
>>> df = pd.DataFrame({"A": [1,2,3], "B": [-2, 8, 1]})
>>> df
   A  B
0  1 -2
1  2  8
2  3  1
>>> df[["A", "B"]]
   A  B
0  1 -2
1  2  8
2  3  1
>>> df[["A", "B"]].max(axis=1)
0    1
1    8
2    3

and so:

>>> df["C"] = df[["A", "B"]].max(axis=1)
>>> df
   A  B  C
0  1 -2  1
1  2  8  8
2  3  1  3

If you know that "A" and "B" are the only columns, you could even get away with

>>> df["C"] = df.max(axis=1)

And you could use .apply(max, axis=1) too, I guess.

I had the same exception, this is how I solved the problem:

Preconditions:

1. Junit class (and test), that extended another class.

2. ApplicationContext initialized using spring, that init the project.

3. The Application context was initialized in @Before method

Solution:

Init the application context from @BeforeClass method, since the parent class also required some classes that were initialized from within the application context.

Hope this will help.

This is common problem for asterisk and this works for me

sudo su

asterisk -rvvv

If not working stop it

sudo su
/etc/init.d/asterisk stop

Start it again

sudo su
/etc/init.d/asterisk start

In Python, every value is a reference (a pointer to an object), just like non-primitives in Java. Also, like Java, Python only has pass by value. So, semantically, they are pretty much the same.

Since you mention Java in your question, I would like to see how you achieve what you want in Java. If you can show it in Java, I can show you how to do it exactly equivalently in Python.

Assgining a value that starts with a "=" will kick in formula evaluation and gave in my case the above mentioned error #1004. Prepending it with a space was the ticket for me.

If you're putting a <meta> tag in your css files, you're doing something wrong. The <meta> tag belongs in your html files, and tells the browser how the html is encoded, it doesn't say anything about the css, which is a separate file. You could conceivably have completely different encodings for your html and css, although I can't imagine this would be a good idea.

An abstract class is a class that can't be instantiated. It's only purpose is for other classes to extend.

Abstract methods are methods in the abstract class (have to be declared abstract) which means the extending concrete class must override them as they have no body.

The main purpose of an abstract class is if you have common code to use in sub classes but the abstract class should not have instances of its own.

You can read more about it here: Abstract Methods and Classes

When you're analyzing code, you have to analyse it line by line, counting every operation/recognizing time complexity, in the end, you have to sum it to get whole picture.

For example, you can have one simple loop with linear complexity, but later in that same program you can have a triple loop that has cubic complexity, so your program will have cubic complexity. Function order of growth comes into play right here.

Let's look at what are possibilities for time complexity of an algorithm, you can see order of growth I mentioned above:

• Constant time has an order of growth 1, for example: a = b + c.

• Logarithmic time has an order of growth LogN, it usually occurs when you're dividing something in half (binary search, trees, even loops), or multiplying something in same way.

• Linear, order of growth is N, for example

  int p = 0;
  for (int i = 1; i < N; i++)
    p = p + 2;
  

• Linearithmic, order of growth is n*logN, usually occurs in divide and conquer algorithms.

• Cubic, order of growth N^3, classic example is a triple loop where you check all triplets:

  int x = 0;
  for (int i = 0; i < N; i++)
     for (int j = 0; j < N; j++)
        for (int k = 0; k < N; k++)
            x = x + 2
  

• Exponential, order of growth 2^N, usually occurs when you do exhaustive search, for example check subsets of some set.

I am assuming (please correct me if I am wrong) that you want to re-display the edit page if the edit fails and to do this you are using a redirect.

You may have more luck by just returning the view again rather than trying to redirect the user, this way you will be able to use the ModelState to output any errors too.

Edit:

Updated based on feedback. You can place the previous URL in the viewModel, add it to a hidden field then use it again in the action that saves the edits.

For instance:

public ActionResult Index()
{
    return View();
}

[HttpGet] // This isn't required
public ActionResult Edit(int id)
{
   // load object and return in view
   ViewModel viewModel = Load(id);

   // get the previous url and store it with view model
   viewModel.PreviousUrl = System.Web.HttpContext.Current.Request.UrlReferrer;

   return View(viewModel);
}

[HttpPost]
public ActionResult Edit(ViewModel viewModel)
{
   // Attempt to save the posted object if it works, return index if not return the Edit view again

   bool success = Save(viewModel);
   if (success)
   {
       return Redirect(viewModel.PreviousUrl);
   }
   else
   {
      ModelState.AddModelError("There was an error");
      return View(viewModel);
   }
}

The BeginForm method for your view doesn't need to use this return URL either, you should be able to get away with:

@model ViewModel

@using (Html.BeginForm())
{
    ...
    <input type="hidden" name="PreviousUrl" value="@Model.PreviousUrl" />
}

Going back to your form action posting to an incorrect URL, this is because you are passing a URL as the 'id' parameter, so the routing automatically formats your URL with the return path.

This won't work because your form will be posting to an controller action that won't know how to save the edits. You need to post to your save action first, then handle the redirect within it.

A working example in widespread use is in modded Minecraft. See EnumHelper.addEnum() methods on Github

However, note that in rare situations practical experience has shown that adding Enum members can lead to some issues with the JVM optimiser. The exact issues may vary with different JVMs. But broadly it seems the optimiser may assume that some internal fields of an Enum, specifically the size of the Enum's .values() array, will not change. See issue discussion. The recommended solution there is not to make .values() a hotspot for the optimiser. So if adding to an Enum's members at runtime, it should be done once and once only when the application is initialised, and then the result of .values() should be cached to avoid making it a hotspot.

The way the optimiser works and the way it detects hotspots is obscure and may vary between different JVMs and different builds of the JVM. If you don't want to take the risk of this type of issue in production code, then don't change Enums at runtime.

"The above text file used has 3 lines of 4 elements separated by commas. The variable numLines prints out as '4' not '3'. So, len(myLines) is returning the number of elements in each list not the length of the list of lists."

It sounds like you're reading in a .csv with 3 rows and 4 columns. If this is the case, you can find the number of rows and lines by using the .split() method:

text = open("filetest.txt", "r").read()
myRows = text.split("\n")      #this method tells Python to split your filetest object each time it encounters a line break 
print len(myRows)              #will tell you how many rows you have
for row in myRows:
  myColumns = row.split(",")   #this method will consider each of your rows one at a time. For each of those rows, it will split that row each time it encounters a comma.  
  print len(myColumns)         #will tell you, for each of your rows, how many columns that row contains

This is caused when java is updated. You have to delete in environement path : C:**ProgramData\Oracle\Java\javapath**

Sure there is! For instance:

<xsl:if test="not(contains($hhref, '1234'))">
  <li>
    <a href="{$hhref}" title="{$pdate}">
      <xsl:value-of select="title"/>
    </a>
  </li>
</xsl:if>

The syntax is: contains(stringToSearchWithin, stringToSearchFor)

I wanted to display the first 300 words of a news story as a preview which unfortunately meant that if a story had an image within the first 300 words then it was displayed in the list of previews which really messed with my layout. I used the above code to hide all of the images from the string taken from my database and it works wonderfully!

$news = $row_latest_news ['content'];
$news = preg_replace("/<img[^>]+\>/i", "", $news); 
if (strlen($news) > 300){
echo substr($news, 0, strpos($news,' ',300)).'...';
} 
else { 
echo $news; 
}

simply don't close in

remove in.close() from your code.

A friend and I have figured out how to call Bernardo Damele's sys_eval UDF, but the solution isn't as elegant as I'd like. Here's what we did:

1. Since we're using Windows, we had to compile the UDF library for Windows using Roland Bouman's instructions and install them on our MySQL server.
2. We created a stored procedure that calls sys_eval.
3. We created a trigger that calls the stored procedure.

Stored Procedure code:

DELIMITER $$
CREATE PROCEDURE udfwrapper_sp
(p1   DOUBLE,
 p2   DOUBLE,
 p3 BIGINT)
BEGIN
 DECLARE cmd CHAR(255);
 DECLARE result CHAR(255);
 SET cmd = CONCAT('C:/xampp/php/php.exe -f "C:/xampp/htdocs/phpFile.php" ', p1, ' ', p2, ' ', p3);
 SET result = sys_eval(cmd);
END$$;

Trigger code:

CREATE TRIGGER udfwrapper_trigger AFTER INSERT ON sometable
FOR EACH ROW
CALL udfwrapper_sp(NEW.Column1, NEW.Column2, NEW.Column3);

I'm not thrilled about having the stored procedure, and I don't know if it creates extra overhead, but it does work. Each time a row is added to sometable, the trigger fires.

If you want to pick columns from a ps output, any reason to not use -o?

e.g.

ps ax -o pid,vsz
ps ax -o pid,cmd

Minimum column width allocated, no padding, only single space field separator.

ps ax --no-headers -o pid:1,vsz:1,cmd

3443 24600 -bash
8419 0 [xfsalloc]
8420 0 [xfs_mru_cache]
8602 489316 /usr/sbin/apache2 -k start
12821 497240 /usr/sbin/apache2 -k start
12824 497132 /usr/sbin/apache2 -k start

Pid and vsz given 10 char width, 1 space field separator.

ps ax --no-headers -o pid:10,vsz:10,cmd

  3443      24600 -bash
  8419          0 [xfsalloc]
  8420          0 [xfs_mru_cache]
  8602     489316 /usr/sbin/apache2 -k start
 12821     497240 /usr/sbin/apache2 -k start
 12824     497132 /usr/sbin/apache2 -k start

Used in a script:-

oldpid=12824
echo "PID: ${oldpid}"
echo "Command: $(ps -ho cmd ${oldpid})"

JRockit Mission Control is becoming Java Mission Control and will be dedicated exclusively to Hotspot. If you are an Oracle customer, you can download the 5.x versions of Java Mission Control from MOS (My Oracle Support). Java Mission Control will eventually be released together with the Oracle JDK. The reason it is not yet generally available is that there are some serious limitations, especially when using the Flight Recorder. However, if you are only interested in using the JMX console, you should be golden!

Full process (Unix svn package):

Check files are not in SVN:

> svn st -u folder 
? folder

Add all (including ignored files):

> svn add folder
A   folder
A   folder/file1.txt
A   folder/folder2
A   folder/folder2/file2.txt
A   folder/folderToIgnore
A   folder/folderToIgnore/fileToIgnore1.txt
A   fileToIgnore2.txt

Remove "Add" Flag to All * Ignore * files:

> cd folder

> svn revert --recursive folderToIgnore
Reverted 'folderToIgnore'
Reverted 'folderToIgnore/fileToIgnore1.txt'


> svn revert fileToIgnore2.txt
Reverted 'fileToIgnore2.txt'

Edit svn ignore on folder

svn propedit svn:ignore .

Add two singles lines with just the following:

folderToIgnore
fileToIgnore2.txt

Check which files will be upload and commit:

> cd ..

> svn st -u
A   folder
A   folder/file1.txt
A   folder/folder2
A   folder/folder2/file2.txt


> svn ci -m "Commit message here"

Now, 2017, you can do it easier with the new MSTest V2 Framework:

Assert.ThrowsException<Exception>(() => myClass.MyMethodWithError());

//async version
await Assert.ThrowsExceptionAsync<SomeException>(
  () => myObject.SomeMethodAsync()
);

In Laravel 5.x, you can also do like this .

<img class="img-responsive" src="{{URL::to('/')}}/img/stuvi-logo.png" alt=""/>

kk: (01-24) will look like 01, 02..24.

HH:(00-23) will look like 00, 01..23.

hh:(01-12 in AM/PM) will look like 01, 02..12.

so the last printout (working2) is a bit weird. It should say 12:00:00 (edit: if you were setting the working2 timezone and format, which (as kdagli pointed out) you are not)

DecimalFormat df=new DecimalFormat("0.00");

Use this code to get exact two decimal points. Even if the value is 0.0 it will give u 0.00 as output.

Instead if you use:

DecimalFormat df=new DecimalFormat("#.00");  

It wont convert 0.2659 into 0.27. You will get an answer like .27.

With Git 2.23 (August 2019), that would be, using git switch -f:

git switch -f master

That avoids the confusion with git checkout (which deals with files or branches).

And that will proceeds, even if the index or the working tree differs from HEAD.
Both the index and working tree are restored to match the switching target.
If --recurse-submodules is specified, submodule content is also restored to match the switching target.
This is used to throw away local changes.

I struggled with this issue for a long time... My solution was to modify the php.ini file, in the folder that contained the php script. This was important, as modifying the php.ini at the root did not resolve the problem (I have a php.ini in each folder for granular control). The relevant entries in my php.ini looked like this.... (the output_buffering is not likely needed for this issue)

output_buffering = On 
upload_max_filesize = 20M 
post_max_size = 21M

$route.reload(); // don't forget to inject $route in your controller
$window.location.reload();
location.reload();

For anyone who wants to find the build directory from a script but does not want to change it, run the following to get a list of all the build settings that point to a folder in DerivedData:

xcodebuild -showBuildSettings | grep DerivedData

If you run custom targets and schemes, please put them there as well:

xcodebuild -workspace "Foo.xcworkspace" -scheme "Bar" -sdk iphonesimulator -configuration Debug -showBuildSettings | grep DerivedData

Look at the output to locate the setting output that you want and then:

xcodebuild -showBuildSettings | grep SYMROOT | cut -d "=" -f 2 - | sed 's/^ *//'

The last part cuts the string at the equal sign and then trims the whitespace at the beginning.

Sorry for answering so late.

I figured an answer alike to @xlm 's:

task run (type: JavaExec, dependsOn: classes){
    if(project.hasProperty('myargs')){
        args(myargs.split(','))
    }
    description = "Secure algorythm testing"
    main = "main.Test"
    classpath = sourceSets.main.runtimeClasspath
}

And invoke like:

gradle run -Pmyargs=-d,s

I coded a function (used in Django project for DecimalField) but it can be used in Python project :

This code :

• Manage integers digits to avoid too high number
• Manage decimals digits to avoid too low number
• Manage signed and unsigned numbers

Code with tests :

def convert_decimal_to_right(value, max_digits, decimal_places, signed=True):

    integer_digits = max_digits - decimal_places
    max_value = float((10**integer_digits)-float(float(1)/float((10**decimal_places))))

    if signed:
        min_value = max_value*-1
    else:
        min_value = 0

    if value > max_value:
        value = max_value

    if value < min_value:
        value = min_value

    return round(value, decimal_places)


value = 12.12345
nb = convert_decimal_to_right(value, 4, 2)
# nb : 12.12

value = 12.126
nb = convert_decimal_to_right(value, 4, 2)
# nb : 12.13

value = 1234.123
nb = convert_decimal_to_right(value, 4, 2)
# nb : 99.99

value = -1234.123
nb = convert_decimal_to_right(value, 4, 2)
# nb : -99.99

value = -1234.123
nb = convert_decimal_to_right(value, 4, 2, signed = False)
# nb : 0

value = 12.123
nb = convert_decimal_to_right(value, 8, 4)
# nb : 12.123

that is the right behavior.

if you set @item1 to a value the below expression will be true

IF (@item1 IS NOT NULL) OR (LEN(@item1) > 0)

Anyway in SQL Server there is not a such function but you can create your own:

CREATE FUNCTION dbo.IsNullOrEmpty(@x varchar(max)) returns bit as
BEGIN
IF @SomeVarcharParm IS NOT NULL AND LEN(@SomeVarcharParm) > 0
    RETURN 0
ELSE
    RETURN 1
END

Simple way is to reset the index of the DataFrame prior to filtering:

df_reset = df.reset_index()
df_reset[df_reset['BoolCol']].index.tolist()

Bit hacky, but it's quick!

Sometimes Window ? Show View does not show the Tasks. Just go to Window ? Show View -> Others and type Tasks in the dialog box.

I did this recently but included double quotes around my values.

For example, change these two lines:

sb.Append("\"" + col.ColumnName + "\","); 
...
sb.Append("\"" + row[i].ToString() + "\","); 

Syntax: ALTER TABLE table_name CHANGE old_column_name new_column_name datatype;

If table name is Student and column name is Name. Then, if you want to change Name to First_Name

ALTER TABLE Student CHANGE Name First_Name varchar(20);

One (dirty) way to do it is to use tryCatch with an empty function for error handling. For example, the following code raises an error and breaks the loop :

for (i in 1:10) {
    print(i)
    if (i==7) stop("Urgh, the iphone is in the blender !")
}

[1] 1
[1] 2
[1] 3
[1] 4
[1] 5
[1] 6
[1] 7
Erreur : Urgh, the iphone is in the blender !

But you can wrap your instructions into a tryCatch with an error handling function that does nothing, for example :

for (i in 1:10) {
  tryCatch({
    print(i)
    if (i==7) stop("Urgh, the iphone is in the blender !")
  }, error=function(e){})
}

[1] 1
[1] 2
[1] 3
[1] 4
[1] 5
[1] 6
[1] 7
[1] 8
[1] 9
[1] 10

But I think you should at least print the error message to know if something bad happened while letting your code continue to run :

for (i in 1:10) {
  tryCatch({
    print(i)
    if (i==7) stop("Urgh, the iphone is in the blender !")
  }, error=function(e){cat("ERROR :",conditionMessage(e), "\n")})
}

[1] 1
[1] 2
[1] 3
[1] 4
[1] 5
[1] 6
[1] 7
ERROR : Urgh, the iphone is in the blender ! 
[1] 8
[1] 9
[1] 10

EDIT : So to apply tryCatch in your case would be something like :

for (v in 2:180){
    tryCatch({
        mypath=file.path("C:", "file1", (paste("graph",names(mydata[columnname]), ".pdf", sep="-")))
        pdf(file=mypath)
        mytitle = paste("anything")
        myplotfunction(mydata[,columnnumber]) ## this function is defined previously in the program
        dev.off()
    }, error=function(e){cat("ERROR :",conditionMessage(e), "\n")})
}

this worked for me :)

select * from Common

where

common_id not in (select ISNULL(common_id,'dummy-data') from Table1)

and common_id not in (select ISNULL(common_id,'dummy-data') from Table2)

Thanks Darin, For me, to be able to post to the create method, It only worked after I modified the BindModel code to :

public override object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
{
    var displayFormat = bindingContext.ModelMetadata.DisplayFormatString;
    var value = bindingContext.ValueProvider.GetValue(bindingContext.ModelName);

    if (!string.IsNullOrEmpty(displayFormat) && value != null)
    {
        DateTime date;
        displayFormat = displayFormat.Replace("{0:", string.Empty).Replace("}", string.Empty);
        // use the format specified in the DisplayFormat attribute to parse the date
         if (DateTime.TryParse(value.AttemptedValue, CultureInfo.GetCultureInfo("en-GB"), DateTimeStyles.None, out date))
        {
            return date;
        }
        else
        {
            bindingContext.ModelState.AddModelError(
                bindingContext.ModelName,
                string.Format("{0} is an invalid date format", value.AttemptedValue)
            );
        }
    }

    return base.BindModel(controllerContext, bindingContext);
}

Hope this could help someone else...

I've created Xcode 4 templates to simplify the steps provided by Tyler.
The result is Python Project Template for Xcode 4.

Now what you need to do is download the templates, move it to /Developer/Library/Xcode/Templates/Project Templates/Mac/Others/ and then new a Python project with Xcode 4.

It still needs manual Scheme setup (you can refer to steps 12–20 provided by Tyler.)

UPDATE 20200825:

Added below "Conclusion" paragraph

I've went down the pipenv rabbit hole (it's a deep and dark hole indeed...) and since the last answer is over 2 years ago, felt it was useful to update the discussion with the latest developments on the Python virtual envelopes topic I've found.

DISCLAIMER:

This answer is NOT about continuing the raging debate about the merits of pipenv versus venv as envelope solutions- I make no endorsement of either. It's about PyPA endorsing conflicting standards and how future development of virtualenv promises to negate making an either/or choice between them at all. I focused on these two tools precisely because they are the anointed ones by PyPA.

venv

As the OP notes, venv is a tool for virtualizing environments. NOT a third party solution, but native tool. PyPA endorses venv for creating VIRTUAL ENVELOPES: "Changed in version 3.5: The use of venv is now recommended for creating virtual environments".

pipenv

pipenv- like venv - can be used to create virtual envelopes but additionally rolls-in package management and vulnerability checking functionality. Instead of using requirements.txt, pipenv delivers package management via Pipfile. As PyPA endorses pipenv for PACKAGE MANAGEMENT, that would seem to imply pipfile is to supplant requirements.txt.

HOWEVER: pipenv uses virtualenv as its tool for creating virtual envelopes, NOT venv which is endorsed by PyPA as the go-to tool for creating virtual envelopes.

Conflicting Standards:

So if settling on a virtual envelope solution wasn't difficult enough, we now have PyPA endorsing two different tools which use different virtual envelope solutions. The raging Github debate on venv vs virtualenv which highlights this conflict can be found here.

Conflict Resolution:

The Github debate referenced in above link has steered virtualenv development in the direction of accommodating venv in future releases:

prefer built-in venv: if the target python has venv we'll create the environment using that (and then perform subsequent operations on that to facilitate other guarantees we offer)

Conclusion:

So it looks like there will be some future convergence between the two rival virtual envelope solutions, but as of now pipenv- which uses virtualenv - varies materially from venv.

Given the problems pipenv solves and the fact that PyPA has given its blessing, it appears to have a bright future. And if virtualenv delivers on its proposed development objectives, choosing a virtual envelope solution should no longer be a case of either pipenv OR venv.

Update 20200825:

An oft repeated criticism of Pipenv I saw when producing this analysis was that it was not actively maintained. Indeed, what's the point of using a solution whose future could be seen questionable due to lack of continuous development? After a dry spell of about 18 months, Pipenv is once again being actively developed. Indeed, large and material updates have since been released.

NetHogs is probably what you're looking for:

a small 'net top' tool. Instead of breaking the traffic down per protocol or per subnet, like most tools do, it groups bandwidth by process.

NetHogs does not rely on a special kernel module to be loaded. If there's suddenly a lot of network traffic, you can fire up NetHogs and immediately see which PID is causing this. This makes it easy to identify programs that have gone wild and are suddenly taking up your bandwidth.

Since NetHogs heavily relies on /proc, most features are only available on Linux. NetHogs can be built on Mac OS X and FreeBSD, but it will only show connections, not processes...

I have my web applications (PRODUCTION, STAGING, TEST) hosted on IIS web server. So it was not possible to rely on ASPNETCORE_ENVIRONMENT operative's system enviroment variable, because setting it to a specific value (for example STAGING) has effect on others applications.

As work-around, I defined a custom file (envsettings.json) within my visualstudio solution:

with following content:

{
  // Possible string values reported below. When empty it use ENV variable value or Visual Studio setting.
  // - Production
  // - Staging
  // - Test
  // - Development
  "ASPNETCORE_ENVIRONMENT": ""
}

Then, based on my application type (Production, Staging or Test) I set this file accordly: supposing I am deploying TEST application, i will have:

"ASPNETCORE_ENVIRONMENT": "Test"

After that, in Program.cs file just retrieve this value and then set the webHostBuilder's enviroment:

    public class Program
    {
        public static void Main(string[] args)
        {
            var currentDirectoryPath = Directory.GetCurrentDirectory();
            var envSettingsPath = Path.Combine(currentDirectoryPath, "envsettings.json");
            var envSettings = JObject.Parse(File.ReadAllText(envSettingsPath));
            var enviromentValue = envSettings["ASPNETCORE_ENVIRONMENT"].ToString();

            var webHostBuilder = new WebHostBuilder()
                .UseKestrel()
                .CaptureStartupErrors(true)
                .UseSetting("detailedErrors", "true")
                .UseContentRoot(currentDirectoryPath)
                .UseIISIntegration()
                .UseStartup<Startup>();

            // If none is set it use Operative System hosting enviroment
            if (!string.IsNullOrWhiteSpace(enviromentValue)) 
            { 
                webHostBuilder.UseEnvironment(enviromentValue);
            }

            var host = webHostBuilder.Build();

            host.Run();
        }
    }

Remember to include the envsettings.json in the publishOptions (project.json):

  "publishOptions":
  {
    "include":
    [
      "wwwroot",
      "Views",
      "Areas/**/Views",
      "envsettings.json",
      "appsettings.json",
      "appsettings*.json",
      "web.config"
    ]
  },

This solution make me free to have ASP.NET CORE application hosted on same IIS, independently from envoroment variable value.

print fast five maximum and minimum number from array without use of sorting array in php :-

<?php  

$array = explode(',',"78, 60, 62, 68, 71, 68, 73, 85, 66, 64, 76, 63, 81, 76, 73,  
68, 72, 73, 75, 65, 74, 63, 67, 65, 64, 68, 73, 75, 79, 73");  
$t=0;  
$l=count($array);  
foreach($array as $v)  
{  
 $t += $v;  
}  
 $avg= $t/$l;  
 echo "average Temperature is : ".$avg."  ";   


echo "<br>List of seven highest temperatsures :-"; 
$m[0]= max($array); 
for($i=1; $i <7 ; $i++)
{ 
$m[$i]=max(array_diff($array,$m));
}
foreach ($m as $key => $value) {
    echo "  ".$value; 
}
echo "<br> List of seven lowest temperatures : ";
$mi[0]= min($array); 
for($i=1; $i <7 ; $i++)
{ 
$mi[$i]=min(array_diff($array,$mi));
}

foreach ($mi as $key => $value) {
    echo "  ".$value; 
}
?>  

I think that this should work:

.element {
   -webkit-transition: all .3s;
   -moz-transition: all .3s;
   -o-transition: all .3s;
   transition: all .3s;
}

Apply this style to your TextBox and that's it (inspired from this article):

<Style x:Key="SelectableTextBlockLikeStyle" TargetType="TextBox" BasedOn="{StaticResource {x:Type TextBox}}">
    <Setter Property="IsReadOnly" Value="True"/>
    <Setter Property="IsTabStop" Value="False"/>
    <Setter Property="BorderThickness" Value="0"/>
    <Setter Property="Background" Value="Transparent"/>
    <Setter Property="Padding" Value="-2,0,0,0"/>
    <!-- The Padding -2,0,0,0 is required because the TextBox
        seems to have an inherent "Padding" of about 2 pixels.
        Without the Padding property,
        the text seems to be 2 pixels to the left
        compared to a TextBlock
    -->

                <Condition Property="IsMouseOver" Value="False" />
                <Condition Property="IsFocused" Value="False" />
            </MultiTrigger.Conditions>
            <Setter Property="Template">

                             Padding="0,0,0,0"

Just use a onchnage Event for select box.

<select id="selectbox" name="" onchange="javascript:location.href = this.value;">
    <option value="https://www.yahoo.com/" selected>Option1</option>
    <option value="https://www.google.co.in/">Option2</option>
    <option value="https://www.gmail.com/">Option3</option>

</select>

And if selected option to be loaded at the page load then add some javascript code

<script type="text/javascript">
    window.onload = function(){
        location.href=document.getElementById("selectbox").value;
    }       
</script>

for jQuery: Remove the onchange event from <select> tag

jQuery(function () {
    // remove the below comment in case you need chnage on document ready
    // location.href=jQuery("#selectbox").val(); 
    jQuery("#selectbox").change(function () {
        location.href = jQuery(this).val();
    })
})

If we are using nodeJS, we should definitely take advantage of different libraries it provides. Inbuilt functions like each(), map(), reduce() and many more from underscoreJS reduces our efforts. Here's a sample

    var _=require("underscore");
    var fs=require("fs");

    var jsonObject=JSON.parse(fs.readFileSync('YourJson.json', 'utf8'));


    _.map( jsonObject, function(content) {
        _.map(content,function(data){
           if(data.Timestamp)
              console.log(data.Timestamp)          
           })
      })

If you use an = statement to assign a value to a var with an object on the right side, javascript will not copy but reference the object.

You can use lodash's clone method

var obj = {a: 25, b: 50, c: 75};
var A = _.clone(obj);

Or lodash's cloneDeep method if your object has multiple object levels

var obj = {a: 25, b: {a: 1, b: 2}, c: 75};
var A = _.cloneDeep(obj);

Or lodash's merge method if you mean to extend the source object

var obj = {a: 25, b: {a: 1, b: 2}, c: 75};
var A = _.merge({}, obj, {newkey: "newvalue"});

Or you can use jQuerys extend method:

var obj = {a: 25, b: 50, c: 75};
var A = $.extend(true,{},obj);

Here is jQuery 1.11 extend method's source code :

jQuery.extend = jQuery.fn.extend = function() {
    var src, copyIsArray, copy, name, options, clone,
        target = arguments[0] || {},
        i = 1,
        length = arguments.length,
        deep = false;

    // Handle a deep copy situation
    if ( typeof target === "boolean" ) {
        deep = target;

        // skip the boolean and the target
        target = arguments[ i ] || {};
        i++;
    }

    // Handle case when target is a string or something (possible in deep copy)
    if ( typeof target !== "object" && !jQuery.isFunction(target) ) {
        target = {};
    }

    // extend jQuery itself if only one argument is passed
    if ( i === length ) {
        target = this;
        i--;
    }

    for ( ; i < length; i++ ) {
        // Only deal with non-null/undefined values
        if ( (options = arguments[ i ]) != null ) {
            // Extend the base object
            for ( name in options ) {
                src = target[ name ];
                copy = options[ name ];

                // Prevent never-ending loop
                if ( target === copy ) {
                    continue;
                }

                // Recurse if we're merging plain objects or arrays
                if ( deep && copy && ( jQuery.isPlainObject(copy) || (copyIsArray = jQuery.isArray(copy)) ) ) {
                    if ( copyIsArray ) {
                        copyIsArray = false;
                        clone = src && jQuery.isArray(src) ? src : [];

                    } else {
                        clone = src && jQuery.isPlainObject(src) ? src : {};
                    }

                    // Never move original objects, clone them
                    target[ name ] = jQuery.extend( deep, clone, copy );

                // Don't bring in undefined values
                } else if ( copy !== undefined ) {
                    target[ name ] = copy;
                }
            }
        }
    }

    // Return the modified object
    return target;
};

Use JavaScript's hasOwnProperty() function:

if (json_object.hasOwnProperty('name')) {
    //do struff
}

You will find much information about JavaDoc at the Documentation Comment Specification for the Standard Doclet, including the information on the

{@link package.class#member label}

tag (that you are looking for). The corresponding example from the documentation is as follows

For example, here is a comment that refers to the getComponentAt(int, int) method:

Use the {@link #getComponentAt(int, int) getComponentAt} method.

The package.class part can be ommited if the referred method is in the current class.

Other useful links about JavaDoc are:

• JavaDoc Tool Reference
• JavaDoc Guide
• How to Write Doc Comments for the Javadoc Tool

.text is correct, the following code works for me:

$('#lb'+(n+1)).text(a[i].attributes[n].name+": "+ a[i].attributes[n].value);

If none of the shortcuts are working (like for me), as a workaround you can also open the command palette (Ctrl + 3 or View -> Command Palette...) and type in fold all:

Here is a working and simple solution for checking existence of a function and triaging that function dynamically by another function;

Trigger function

function runDynmicFunction(functionname){ 

    if (typeof window[functionname] == "function"  ) { //check availability

        window[functionname]("this is from the function it "); //run function and pass a parameter to it
    }
}

and you can now generate the function dynamically maybe using php like this

function runThis_func(my_Parameter){

    alert(my_Parameter +" triggerd");
}

now you can call the function using dynamically generated event

<?php

$name_frm_somware ="runThis_func";

echo "<input type='button' value='Button' onclick='runDynmicFunction(\"".$name_frm_somware."\");'>";

1: No difference. It is kept around to allow old S-code to continue to function. This is documented a "Note" in ?Math

2: Yes: But you already know it:

`^`(x,y)
#[1] 1024

In R the mathematical operators are really functions that the parser takes care of rearranging arguments and function names for you to simulate ordinary mathematical infix notation. Also documented at ?Math.

Edit: Let me add that knowing how R handles infix operators (i.e. two argument functions) is very important in understanding the use of the foundational infix "[[" and "["-functions as (functional) second arguments to lapply and sapply:

> sapply( list( list(1,2,3), list(4,3,6) ), "[[", 1)
[1] 1 4
> firsts <- function(lis) sapply(lis, "[[", 1)
> firsts( list( list(1,2,3), list(4,3,6) ) )
[1] 1 4

This solution works nice when using Latin American accents, such as 'ñ'.

I have solved this problem just by adding

df = pd.read_csv(fileName,encoding='latin1')

R has a number of (undocumented) convenience functions for converting factors:

• as.character.factor
• as.data.frame.factor
• as.Date.factor
• as.list.factor
• as.vector.factor
• ...

But annoyingly, there is nothing to handle the factor -> numeric conversion. As an extension of Joshua Ulrich's answer, I would suggest to overcome this omission with the definition of your own idiomatic function:

as.numeric.factor <- function(x) {as.numeric(levels(x))[x]}

that you can store at the beginning of your script, or even better in your .Rprofile file.

Do not forget the . at the end, which indicates end of line

Edit: After Docker 1.9, the docker network command (see below https://stackoverflow.com/a/35184695/977939) is the recommended way to achieve this.

My solution is to set up a dnsmasq on the host to have DNS record automatically updated: "A" records have the names of containers and point to the IP addresses of the containers automatically (every 10 sec). The automatic updating script is pasted here:

#!/bin/bash

# 10 seconds interval time by default
INTERVAL=${INTERVAL:-10}

# dnsmasq config directory
DNSMASQ_CONFIG=${DNSMASQ_CONFIG:-.}

# commands used in this script
DOCKER=${DOCKER:-docker}
SLEEP=${SLEEP:-sleep}
TAIL=${TAIL:-tail}

declare -A service_map

while true
do
    changed=false
    while read line
    do
        name=${line##* }
        ip=$(${DOCKER} inspect --format '{{.NetworkSettings.IPAddress}}' $name)
        if [ -z ${service_map[$name]} ] || [ ${service_map[$name]} != $ip ] # IP addr changed
        then
            service_map[$name]=$ip
            # write to file
            echo $name has a new IP Address $ip >&2
            echo "host-record=$name,$ip"  > "${DNSMASQ_CONFIG}/docker-$name"
            changed=true
        fi
    done < <(${DOCKER} ps | ${TAIL} -n +2)

    # a change of IP address occured, restart dnsmasq
    if [ $changed = true ]
    then
        systemctl restart dnsmasq
    fi

    ${SLEEP} $INTERVAL
done

Make sure your dnsmasq service is available on docker0. Then, start your container with --dns HOST_ADDRESS to use this mini dns service.

I had this issue , When calling Generic.List like:

mylist.Select( selectFunc )

Where selectFunc is defined as Expression<Func<T, List<string>>>. Simply changed "mylist" to be a IQuerable instead of List then it allowed me to use .Select.

Pretty-printing is implemented natively in JSON.stringify(). The third argument enables pretty printing and sets the spacing to use:

var str = JSON.stringify(obj, null, 2); // spacing level = 2

If you need syntax highlighting, you might use some regex magic like so:

function syntaxHighlight(json) {
    if (typeof json != 'string') {
         json = JSON.stringify(json, undefined, 2);
    }
    json = json.replace(/&/g, '&amp;').replace(/</g, '&lt;').replace(/>/g, '&gt;');
    return json.replace(/("(\\u[a-zA-Z0-9]{4}|\\[^u]|[^\\"])*"(\s*:)?|\b(true|false|null)\b|-?\d+(?:\.\d*)?(?:[eE][+\-]?\d+)?)/g, function (match) {
        var cls = 'number';
        if (/^"/.test(match)) {
            if (/:$/.test(match)) {
                cls = 'key';
            } else {
                cls = 'string';
            }
        } else if (/true|false/.test(match)) {
            cls = 'boolean';
        } else if (/null/.test(match)) {
            cls = 'null';
        }
        return '<span class="' + cls + '">' + match + '</span>';
    });
}

document.location is a synonym for window.location that has been deprecated for almost as long as JavaScript has existed. Don't use it.

location is a structured object, with properties corresponding to the parts of the URL. location.href is the whole URL in a single string. Assigning a string to either is defined to cause the same kind of navigation, so take your pick.

I consider writing to location.href = something to be marginally better as it's slightly more explicit about what it's doing. You generally want to avoid just location = something as it looks misleadingly like a variable assignment. window.location = something is fine though.

I realize this is somewhat of an older post, but for anyone that comes to this page looking for a similar solution...

http://api.jquery.com/jQuery.getScript/

jQuery.getScript( url, [ success(data, textStatus) ] )

• url - A string containing the URL to which the request is sent.

• success(data, textStatus) - A callback function that is executed if the request succeeds.

$.getScript('ajax/test.js', function() {
  alert('Load was performed.');
});

No, that's pretty much it. In theory you could use visibility: collapse on some <col>?s to do it, but browser support isn't all there.

To improve what you've got slightly, you could use table-layout: fixed on the <table> to allow the browser to use the simpler, faster and more predictable fixed-table-layout algorithm. You could also drop the .show rules as when a cell isn't made display: none by a .hide rule it will automatically be display: table-cell. Allowing table display to revert to default rather than setting it explicitly avoids problems in IE<8, where the table display values are not supported.

I've been facing this problem for long but what this solves my problem Go inside the tsconfig.json and add the following under compilerOptions

{
  "compilerOptions": {
      ...
      "allowJs": true
      ...
  }
}

the xcode UI has changed a bit from one version to the next so here is where you update the plist for 9.0 beta 4 if it helps Project ->Target ->Info

For Matching the ID:

Select * from table_name where 1=1

For Matching the Pattern:

Select * from table_name column_name Like '%string%'

I typically free every allocated block once I'm sure that I'm done with it. Today, my program's entry point might be main(int argc, char *argv[]) , but tomorrow it might be foo_entry_point(char **args, struct foo *f) and typed as a function pointer.

So, if that happens, I now have a leak.

Regarding your second question, if my program took input like a=5, I would allocate space for a, or re-allocate the same space on a subsequent a="foo". This would remain allocated until:

1. The user typed 'unset a'
2. My cleanup function was entered, either servicing a signal or the user typed 'quit'

I can not think of any modern OS that does not reclaim memory after a process exits. Then again, free() is cheap, why not clean up? As others have said, tools like valgrind are great for spotting leaks that you really do need to worry about. Even though the blocks you example would be labeled as 'still reachable' , its just extra noise in the output when you're trying to ensure you have no leaks.

Another myth is "If its in main(), I don't have to free it", this is incorrect. Consider the following:

char *t;

for (i=0; i < 255; i++) {
    t = strdup(foo->name);
    let_strtok_eat_away_at(t);
}

If that came prior to forking / daemonizing (and in theory running forever), your program has just leaked an undetermined size of t 255 times.

A good, well written program should always clean up after itself. Free all memory, flush all files, close all descriptors, unlink all temporary files, etc. This cleanup function should be reached upon normal termination, or upon receiving various kinds of fatal signals, unless you want to leave some files laying around so you can detect a crash and resume.

Really, be kind to the poor soul who has to maintain your stuff when you move on to other things .. hand it to them 'valgrind clean' :)

If both the list are too big and when we use lamda expression then it will take a long time to fetch . Better to use linq in this case to fetch parameters list:

var items = (from x in parameters
                join y in myStrings on x.Source equals y
                select x)
            .ToList();

You should \usepackage{longtable}.

• PDF Documentation of the package: ftp://ftp.tex.ac.uk/tex-archive/macros/latex/required/tools/longtable.pdf
• Tutorial with examples can be found here.

SELECT t1.col table1col, t2.col table2col
FROM table1 t1 
JOIN table2 t2 on t1.table1Id = x and t2.table2Id = y

Personally, I would use the following function:

var arrayContains = function(array, toMatch) {
    var arrayAsString = array.toString();
    return (arrayAsString.indexOf(','+toMatch+',') >-1);
}

The "toString()" method will always use commas to separate the values. Will only really work with primitive types.

Goodness I had a hard time finding the answer to this... Here it is:

cd thisDoesntExist
if %errorlevel% == 0 (
  echo Oh, I guess it does
  echo Huh.
)

\t is the tab character, and is doing exactly what you're anticipating based on the action of \b - it goes to the next tab stop, then gets decremented, and then goes to the next tab stop (which is in this case the same tab stop, because of the \b.

OS X / macOS / FreeBSD sed

The -i flag works differently on macOS sed than in GNU sed.

Here's the way to use it on macOS / OS X:

sed -i '' '8i\
8 This is Line 8' FILE

See man 1 sed for more info.

It's a part of ISO-8601 date representation. It's incomplete because a complete date representation in this pattern should also contains the date:

2015-03-04T00:00:00.000Z //Complete ISO-8601 date

If you try to parse this date as it is you will receive an Invalid Date error:

new Date('T00:00:00.000Z'); // Invalid Date

So, I guess the way to parse a timestamp in this format is to concat with any date

new Date('2015-03-04T00:00:00.000Z'); // Valid Date

Then you can extract only the part you want (timestamp part)

var d = new Date('2015-03-04T00:00:00.000Z');
console.log(d.getUTCHours()); // Hours
console.log(d.getUTCMinutes());
console.log(d.getUTCSeconds());

Accordingly to W3C checked input's attribute can be absent/ommited or have "checked" as its value. This does not invalidate other values because there's no restriction to the browser implementation to allow values like "true", "on", "yes" and so on. To guarantee that you'll write a cross-browser checkbox/radio use checked="checked", as recommended by W3C.

disabled, readonly and ismap input's attributes go on the same way.

EDITED

empty is not a valid value for checked, disabled, readonly and ismap input's attributes, as warned by @Quentin

The settings you need are "Local echo" and "Line editing" under the "Terminal" category on the left.

To get the characters to display on the screen as you enter them, set "Local echo" to "Force on".

To get the terminal to not send the command until you press Enter, set "Local line editing" to "Force on".

Explanation:

From the PuTTY User Manual (Found by clicking on the "Help" button in PuTTY):

4.3.8 ‘Local echo’

With local echo disabled, characters you type into the PuTTY window are not echoed in the window by PuTTY. They are simply sent to the server. (The server might choose to echo them back to you; this can't be controlled from the PuTTY control panel.)

Some types of session need local echo, and many do not. In its default mode, PuTTY will automatically attempt to deduce whether or not local echo is appropriate for the session you are working in. If you find it has made the wrong decision, you can use this configuration option to override its choice: you can force local echo to be turned on, or force it to be turned off, instead of relying on the automatic detection.

4.3.9 ‘Local line editing’ Normally, every character you type into the PuTTY window is sent immediately to the server the moment you type it.

If you enable local line editing, this changes. PuTTY will let you edit a whole line at a time locally, and the line will only be sent to the server when you press Return. If you make a mistake, you can use the Backspace key to correct it before you press Return, and the server will never see the mistake.

Since it is hard to edit a line locally without being able to see it, local line editing is mostly used in conjunction with local echo (section 4.3.8). This makes it ideal for use in raw mode or when connecting to MUDs or talkers. (Although some more advanced MUDs do occasionally turn local line editing on and turn local echo off, in order to accept a password from the user.)

Some types of session need local line editing, and many do not. In its default mode, PuTTY will automatically attempt to deduce whether or not local line editing is appropriate for the session you are working in. If you find it has made the wrong decision, you can use this configuration option to override its choice: you can force local line editing to be turned on, or force it to be turned off, instead of relying on the automatic detection.

Putty sometimes makes wrong choices when "Auto" is enabled for these options because it tries to detect the connection configuration. Applied to serial line, this is a bit trickier to do.

You cannot add a column with a default value in Hive. You have the right syntax for adding the column ALTER TABLE test1 ADD COLUMNS (access_count1 int);, you just need to get rid of default sum(max_count). No changes to that files backing your table will happen as a result of adding the column. Hive handles the "missing" data by interpreting NULL as the value for every cell in that column.

So now your have the problem of needing to populate the column. Unfortunately in Hive you essentially need to rewrite the whole table, this time with the column populated. It may be easier to rerun your original query with the new column. Or you could add the column to the table you have now, then select all of its columns plus value for the new column.

You also have the option to always COALESCE the column to your desired default and leave it NULL for now. This option fails when you want NULL to have a meaning distinct from your desired default. It also requires you to depend on always remembering to COALESCE.

If you are very confident in your abilities to deal with the files backing Hive, you could also directly alter them to add your default. In general I would recommend against this because most of the time it will be slower and more dangerous. There might be some case where it makes sense though, so I've included this option for completeness.

In your render function:

{ this.state.showTheThing && 
  <TextInput/>
}

Then just do:

this.setState({showTheThing: true})  // to show it  
this.setState({showTheThing: false}) // to hide it

You can intercept the key press events, cancel the lowercase ones, and append their uppercase versions to the input:

window.onload = function () {
    var input = document.getElementById("test");

    input.onkeypress = function () {
        // So that things work both on Firefox and Internet Explorer.
        var evt = arguments[0] || event;
        var char = String.fromCharCode(evt.which || evt.keyCode);

        // Is it a lowercase character?
        if (/[a-z]/.test(char)) {
            // Append its uppercase version
            input.value += char.toUpperCase();

            // Cancel the original event
            evt.cancelBubble = true;
            return false;
        }
    }
};

This works in both Firefox and Internet Explorer. You can see it in action here.

Take a look at StackOverflow #4348018 - List of Facebook error codes for a number of useful resources.

@laconbass's answer helped me and is probably most correct.

I came here because I was using spawn incorrectly. As a simple example:

this is incorrect:

const s = cp.spawn('npm install -D suman', [], {
    cwd: root
});

this is incorrect:

const s = cp.spawn('npm', ['install -D suman'], {
    cwd: root
});

this is correct:

const s = cp.spawn('npm', ['install','-D','suman'], {
    cwd: root
});

however, I recommend doing it this way:

const s = cp.spawn('bash');
s.stdin.end(`cd "${root}" && npm install -D suman`);
s.once('exit', code => {
   // exit
});

this is because then the cp.on('exit', fn) event will always fire, as long as bash is installed, otherwise, the cp.on('error', fn) event might fire first, if we use it the first way, if we launch 'npm' directly.

Use border-collapse and border-spacing to get spaces between the table cells. I would not recommend using floating cells as suggested by QQping.

A simple, fast way to get the content by id :

echo get_post_field('post_content', $id);

And if you want to get the content formatted :

echo apply_filters('the_content', get_post_field('post_content', $id));

Works with pages, posts & custom posts.

Welcome to Microsoft Marketing Speak hell. With the 2012 release of SQL Server, the BIDS, Business Intelligence Designer Studio, plugin for Visual Studio was renamed to SSDT, SQL Server Data Tools. SSDT is available for 2010 and 2012. The problem is, there are two different products called SSDT.

There is SSDT which replaces the database designer thing which was called Data Dude in VS 2008 and in 2010 became database projects. That a free install and if you snag the web installer, that's what you get when you install SSDT. It puts the correct project templates and such into Visual Studio.

There's also the SSDT which is the "BIDS" replacement for developing SSIS, SSRS and SSAS stuff. As of March 2013, it is now available for the 2012 release of Visual Studio. The download is labeled SSDTBI_VS2012_X86.msi Perhaps that's a signal on how the product is going to be referred to in marketing materials. Download links are

• Microsoft SQL Server Data Tools Business Intelligence for Visual Studio 2012 (SSIS packages target SQL Server 2012)
• Microsoft SQL Server Data Tools Business Intelligence for Visual Studio 2013 (SSIS packages target SQL Server 2014)

None the less, we have Business Intelligence projects available to us in Visual Studio 2012. And the people did rejoice and did feast upon the lambs and toads and tree-sloths and fruit-bats and orangutans and breakfast cereals

When Card I always use RoundedRectangleBorder.

Card(
  color: Colors.grey[900],
  shape: RoundedRectangleBorder(
    side: BorderSide(color: Colors.white70, width: 1),

Our HTML:

<div id="addnew">
    <input type="text" id="id">
    <input type="text" id="content">
    <input type="button" value="Add" id="submit">
</div>

<div id="check">
    <input type="text" id="input">
    <input type="button" value="Search" id="search">
</div>

JS (writing to the txt file):

function writeToFile(d1, d2){
    var fso = new ActiveXObject("Scripting.FileSystemObject");
    var fh = fso.OpenTextFile("data.txt", 8, false, 0);
    fh.WriteLine(d1 + ',' + d2);
    fh.Close();
}
var submit = document.getElementById("submit");
submit.onclick = function () {
    var id      = document.getElementById("id").value;
    var content = document.getElementById("content").value;
    writeToFile(id, content);
}

checking a particular row:

function readFile(){
    var fso = new ActiveXObject("Scripting.FileSystemObject");
    var fh = fso.OpenTextFile("data.txt", 1, false, 0);
    var lines = "";
    while (!fh.AtEndOfStream) {
        lines += fh.ReadLine() + "\r";
    }
    fh.Close();
    return lines;
}
var search = document.getElementById("search");
search.onclick = function () {
    var input   = document.getElementById("input").value;
    if (input != "") {
        var text    = readFile();
        var lines   = text.split("\r");
        lines.pop();
        var result;
        for (var i = 0; i < lines.length; i++) {
            if (lines[i].match(new RegExp(input))) {
                result = "Found: " + lines[i].split(",")[1];
            }
        }
        if (result) { alert(result); }
        else { alert(input + " not found!"); }
    }
}

Put these inside a .hta file and run it. Tested on W7, IE11. It's working. Also if you want me to explain what's going on, say so.

One can invoke mysqldump locally against a remote server.

Example that worked for me:

mysqldump -h hostname-of-the-server -u mysql_user -p database_name > file.sql

I followed the mysqldump documentation on connection options.

.removeAttr("style") to just get rid of the whole style tag...

.attr("style") to test the value and see if an inline style exists...

.attr("style",newValue) to set it to something else

If you are familiar with C++ and macros, then

#import "Class.h" 

is similar to

{
#pragma once

#include "class.h"
}

which means that your Class will be loaded only once when your app runs.

This solved my problem

var url = "http://localhost/tech1/index.php?route=app/upload/ajax"; 

$.ajax({
  xhr: function() {
    var xhr = new window.XMLHttpRequest();

    xhr.upload.addEventListener("progress", function(evt) {
      if (evt.lengthComputable) {
        var percentComplete = evt.loaded / evt.total;
        percentComplete = parseInt(percentComplete * 100);
var $link = $('.'+ids);
          var $img = $link.find('i'); 
          $link.html('Uploading..('+percentComplete+'%)');
          $link.append($img);
      }
    }, false);

    return xhr;
  },
  url: url,
  type: "POST",
  data: JSON.stringify(uploaddata),
  contentType: "application/json",
  dataType: "json",
  success: function(result) {
    console.log(result);
  }
});

Firstly, in a character class [...] most characters don't need escaping - they are just literals.

So, your regex should be:

"[\[\]?*+|{}\\()@.\n\r]"

This compiles for me.

Maven remembers when it didn't find something. The key is "resolution will not be reattempted until the update interval of internal has elapsed or updates are forced ->"

The quick solution is to delete your local "repository" subdirectory for the problem artifact - assuming you have fixed the problem with it. :)

mvn -U will force update from remote repository - again, assuming you have now populated remote with said artifact.

The Media Source Extensions has been proposed which would allow for Adaptive Bitrate Streaming implementations.

grep -Fx ABB.log a.tmp

From the grep man page:

-F, --fixed-strings
Interpret PATTERN as a (list of) fixed strings
-x, --line-regexp
Select only those matches that exactly match the whole line.

An other solution is to use the response.status function. This will give you the http status wich is returned by the ajax call.

function checkHttpStatus(url) {     
    $.ajax({
        type: "GET",
        data: {},
        url: url,
        error: function(response) {
            alert(url + " returns a " + response.status);
        }, success() {
            alert(url + " Good link");
        }
    });
}

This is another approach.

render() {
   return {this[`renderStep${this.state.step}`]()}

renderStep0() { return 'step 0' }
renderStep1() { return 'step 1' }

Using [String.indexOf][1]

var stringToMatch = "XYZ 123 ABC 456 ABC 789 ABC";

function yetAnotherGetNthOccurance(string, seek, occurance) {
    var index = 0, i = 1;

    while (index !== -1) {
        index = string.indexOf(seek, index + 1);
        if (occurance === i) {
           break;
        }
        i++;
    }
    if (index !== -1) {
        console.log('Occurance found in ' + index + ' position');
    }
    else if (index === -1 && i !== occurance) {
        console.log('Occurance not found in ' + occurance + ' position');
    }
    else {
        console.log('Occurance not found');
    }
}

yetAnotherGetNthOccurance(stringToMatch, 'ABC', 2);

// Output: Occurance found in 16 position

yetAnotherGetNthOccurance(stringToMatch, 'ABC', 20);

// Output: Occurance not found in 20 position

yetAnotherGetNthOccurance(stringToMatch, 'ZAB', 1)

// Output: Occurance not found

In Visual Studio 2012 +/-, the property page for "Configuration Properties'.Linker."Command Line" contains a box labeled "Additional Options". If you're building x64, make sure that box doesn't contain /MACHINE:I386. My projects did and it generated the error in question.

Ok. So, I know this is an old post, but perhaps this can help someone else. This is not backwards compatible, but that's almost irrelevant since Internet Explorer is being made redundant.

Easiest way to do exactly what is wanted:

function findInJson(objJsonResp, key, value, aType){        
     if(aType=="edit"){
        return objJsonResp.find(x=> x[key] == value);
     }else{//delete
         var a =objJsonResp.find(x=> x[key] == value);
         objJsonResp.splice(objJsonResp.indexOf(a),1);
     }
}

It will return the item you want to edit if you supply 'edit' as the type. Supply anything else, or nothing, and it assumes delete. You can flip the conditionals if you'd prefer.

UEFA or FIFA don't seem to provide any API to get the information you want. However, there are some third-party services which support that:

• OPTA - Both commercial and free. They have incredible database about matches. Whoscored.com currently uses it.

• Others: livescoreboards, xmlsoccer, ...

Keep a friend table that holds the UserID and then the UserID of the friend (we will call it FriendID). Both columns would be foreign keys back to the Users table.

Somewhat useful example:

Table Name: User
Columns:
    UserID PK
    EmailAddress
    Password
    Gender
    DOB
    Location

TableName: Friends
Columns:
    UserID PK FK
    FriendID PK FK
    (This table features a composite primary key made up of the two foreign 
     keys, both pointing back to the user table. One ID will point to the
     logged in user, the other ID will point to the individual friend
     of that user)

Example Usage:

Table User
--------------
UserID EmailAddress Password Gender DOB      Location
------------------------------------------------------
1      [email protected]  bobbie   M      1/1/2009 New York City
2      [email protected]  jonathan M      2/2/2008 Los Angeles
3      [email protected]  joseph   M      1/2/2007 Pittsburgh

Table Friends
---------------
UserID FriendID
----------------
1      2
1      3
2      3

This will show that Bob is friends with both Jon and Joe and that Jon is also friends with Joe. In this example we will assume that friendship is always two ways, so you would not need a row in the table such as (2,1) or (3,2) because they are already represented in the other direction. For examples where friendship or other relations aren't explicitly two way, you would need to also have those rows to indicate the two-way relationship.

As per my understanding you want data in dictionary as shown below:

key1: value1-1,value1-2,value1-3....value100-1
key2: value2-1,value2-2,value2-3....value100-2
key3: value3-1,value3-2,value3-2....value100-3

for this you can use list for each dictionary keys:

case_list = {}
for entry in entries_list:
    if key in case_list:
        case_list[key1].append(value)
    else:
        case_list[key1] = [value]

After reading some more document, I found the solution:

https://github.com/ReactTraining/react-router/blob/master/packages/react-router/docs/api/location.md

I just need to access the injected property location of the instance of the component like:

var currentLocation = this.props.location.pathname

As far as Angular CLI: 7.1.4, there are two common ways to achieve changing the default port.

No. 1

In the angular.json, add the --port option to serve part and use ng serve to start the server.

"serve": {
  "builder": "@angular-devkit/build-angular:dev-server",
  "options": {
    "browserTarget": "demos:build",
    "port": 1337
  },
  "configurations": {
    "production": {
      "browserTarget": "demos:build:production"
    }
  }
},

No. 2

In the package.json, add the --port option to ng serve and use npm start to start the server.

  "scripts": {
    "ng": "ng",
    "start": "ng serve --port 8000",
    "build": "ng build",
    "test": "ng test",
    "lint": "ng lint",
    "e2e": "ng e2e"
  }, 

Here is the complete sequence for sql server :

1.  FROM
2.  ON
3.  JOIN
4.  WHERE
5.  GROUP BY
6.  WITH CUBE or WITH ROLLUP
7.  HAVING
8.  SELECT
9.  DISTINCT
10. ORDER BY
11. TOP

So from the above list, you can easily understand the execution sequence of GROUP BY, HAVING and WHERE which is :

1.  WHERE
2.  GROUP BY
3.  HAVING

I made a POC for an Angular application using multiple modules and router-outlets to nest sub apps in a single page app. You can get the source code at: https://github.com/AhmedBahet/ng-sub-apps

Hope this will help

Arrays are pretty flexible in JS, you can do:

var myArray = new Array();
myArray.push("string 1");
myArray.push("string 2");

For those who didn't see Johns comment to carlos solution ...

req.Content.Headers.ContentType = new MediaTypeHeaderValue("application/octet-stream");

Short answer:

const base64Canvas = canvas.toDataURL("image/jpeg").split(';base64,')[1];

When you want to count the frequency of categorical data in a column in pandas dataFrame use: df['Column_Name'].value_counts()

git rev-parse Also works for getting the current branch name using the --abbrev-ref flag like:

git rev-parse --abbrev-ref HEAD

Both UTF8 and UTF-8 work for me.

Have done a number of comparisons between left outer and inner joins and have not been able to find a consisten difference. There are many variables. Am working on a reporting database with thousands of tables many with a large number of fields, many changes over time (vendor versions and local workflow) . It is not possible to create all of the combinations of covering indexes to meet the needs of such a wide variety of queries and handle historical data. Have seen inner queries kill server performance because two large (millions to tens of millions of rows) tables are inner joined both pulling a large number of fields and no covering index exists.

The biggest issue though, doesn't seem to appeaer in the discussions above. Maybe your database is well designed with triggers and well designed transaction processing to ensure good data. Mine frequently has NULL values where they aren't expected. Yes the table definitions could enforce no-Nulls but that isn't an option in my environment.

So the question is... do you design your query only for speed, a higher priority for transaction processing that runs the same code thousands of times a minute. Or do you go for accuracy that a left outer join will provide. Remember that inner joins must find matches on both sides, so an unexpected NULL will not only remove data from the two tables but possibly entire rows of information. And it happens so nicely, no error messages.

You can be very fast as getting 90% of the needed data and not discover the inner joins have silently removed information. Sometimes inner joins can be faster, but I don't believe anyone making that assumption unless they have reviewed the execution plan. Speed is important, but accuracy is more important.
