If you have multiple projects in your solution and one of your projects fails to build because of this error then ensure you have installed the WebApi Core nuget package in that project. Simply adding a reference to the System.Web.Http does not help, you need to install the correct nuget package into that project.

I had multiple projects in my solution and WebApi Core was already installed in another project. I referenced the System.Web.Http assembly by right-clicking and ticking the assembly from the list and it did not work on Azure, though locally it would build okay. I had to remove the manual reference and add the WebApi Core nuget package to each project that needed the assembly reference.

It's very simple....

1. Open pyScripter or any editor
2. Create a python file eg: install.py
3. write the below code in it.

import nltk
nltk.download()

4. A pop-up window will apper and click on download .

This can be achieved using a Spannable String. You will need to import the following

import android.text.SpannableString; 
import android.text.style.BackgroundColorSpan; 
import android.text.style.StyleSpan;

And then you can change the background of the text using something like the following:

TextView text = (TextView) findViewById(R.id.text_login);
text.setText("");
text.append("Add all your funky text in here");
Spannable sText = (Spannable) text.getText();
sText.setSpan(new BackgroundColorSpan(Color.RED), 1, 4, 0);

Where this will highlight the charecters at pos 1 - 4 with a red color. Hope this helps!

The followed works on ubuntu 12.04:

pip uninstall PIL
apt-get install libjpeg-dev
apt-get install libfreetype6-dev
apt-get install zlib1g-dev
apt-get install libpng12-dev
pip install PIL --upgrade

when your see "-- JPEG support avaliable" that means it works.

But, if it still doesn't work when your edit your jpeg image, check the python path !! my python path missed /usr/local/lib/python2.7/dist-packages/PIL-1.1.7-py2.7-linux-x86_64.egg/, so I edit the ~/.bashrc add the following code to this file:

Edit: export PYTHONPATH=$PYTHONPATH:/usr/local/lib/python2.7/dist-packages/PIL-1.1.7-py2.7-linux-x86_64.egg/

then, finally, it works!!

Conceptually speaking, keeping the language specific implementation, rules, benefits and achieving any programming goal by using anyone or both, can or cant have code/data/property, blah blah, single or multiple inheritances, all aside

1- Abstract (or pure abstract) Class is meant to implement hierarchy. If your business objects look somewhat structurally similar, representing a parent-child (hierarchy) kind of relationship only then inheritance/Abstract classes will be used. If your business model does not have a hierarchy then inheritance should not be used (here I am not talking about programming logic e.g. some design patterns require inheritance). Conceptually, abstract class is a method to implement hierarchy of a business model in OOP, it has nothing to do with Interfaces, actually comparing Abstract class with Interface is meaningless because both are conceptually totally different things, it is asked in interviews just to check the concepts because it looks both provide somewhat same functionality when implementation is concerned and we programmers usually emphasize more on coding. [Keep this in mind as well that Abstraction is different than Abstract Class].

2- an Interface is a contract, a complete business functionality represented by one or more set of functions. That is why it is implemented and not inherited. A business object (part of a hierarchy or not) can have any number of complete business functionality. It has nothing to do with abstract classes means inheritance in general. For example, a human can RUN, an elephant can RUN, a bird can RUN, and so on, all these objects of different hierarchy would implement the RUN interface or EAT or SPEAK interface. Don't go into implementation as you might implement it as having abstract classes for each type implementing these interfaces. An object of any hierarchy can have a functionality(interface) which has nothing to do with its hierarchy.

I believe, Interfaces were not invented to achieve multiple inheritances or to expose public behavior, and similarly, pure abstract classes are not to overrule interfaces but Interface is a functionality that an object can do (via functions of that interface) and Abstract Class represents a parent of a hierarchy to produce children having core structure (property+functionality) of the parent

When you are asked about the difference, it is actually conceptual difference not the difference in language-specific implementation unless asked explicitly.

I believe, both interviewers were expecting one line straightforward difference between these two and when you failed they tried to drove you towards this difference by implementing ONE as the OTHER

What if you had an Abstract class with only abstract methods?

Another possibility would be to set the Working Directory under the debugging options to be the directory that has that DLL.

Edit: I was going to mention using a batch file to start Visual Studio (and set the PATH variable in the batch file). So then did a bit of searching and see that this exact same question was asked not long ago in this post. The answer suggests the batch file option as well as project settings that apparently may do the job (I did not test it).

this function will join 2 tables with a known join field, but this cannot allow 2 fields with the same name on both tables except the join field, a simple modification would be to save a dictionary with a counter and just add number to the same name filds.

public static DataTable JoinDataTable(DataTable dataTable1, DataTable dataTable2, string joinField)
{
    var dt = new DataTable();
    var joinTable = from t1 in dataTable1.AsEnumerable()
                            join t2 in dataTable2.AsEnumerable()
                                on t1[joinField] equals t2[joinField]
                            select new { t1, t2 };

    foreach (DataColumn col in dataTable1.Columns)
        dt.Columns.Add(col.ColumnName, typeof(string));

    dt.Columns.Remove(joinField);

    foreach (DataColumn col in dataTable2.Columns)
        dt.Columns.Add(col.ColumnName, typeof(string));

    foreach (var row in joinTable)
    {
        var newRow = dt.NewRow();
        newRow.ItemArray = row.t1.ItemArray.Union(row.t2.ItemArray).ToArray();
        dt.Rows.Add(newRow);
    }
    return dt;
}

this is how:

Here is working example for a generic <table>. (question links-broken)

Extracting the table from here countries by GDP (Gross Domestic Product).

htmltable = soup.find('table', { 'class' : 'table table-striped' })
# where the dictionary specify unique attributes for the 'table' tag

The tableDataText function parses a html segment started with tag <table> followed by multiple <tr> (table rows) and inner <td> (table data) tags. It returns a list of rows with inner columns. Accepts only one <th> (table header/data) in the first row.

def tableDataText(table):       
    rows = []
    trs = table.find_all('tr')
    headerow = [td.get_text(strip=True) for td in trs[0].find_all('th')] # header row
    if headerow: # if there is a header row include first
        rows.append(headerow)
        trs = trs[1:]
    for tr in trs: # for every table row
        rows.append([td.get_text(strip=True) for td in tr.find_all('td')]) # data row
    return rows

Using it we get (first two rows).

list_table = tableDataText(htmltable)
list_table[:2]

[['Rank',
  'Name',
  "GDP (IMF '19)",
  "GDP (UN '16)",
  'GDP Per Capita',
  '2019 Population'],
 ['1',
  'United States',
  '21.41 trillion',
  '18.62 trillion',
  '$65,064',
  '329,064,917']]

That can be easily transformed in a pandas.DataFrame for more advanced tools.

import pandas as pd
dftable = pd.DataFrame(list_table[1:], columns=list_table[0])
dftable.head(4)

The best way comes from James Riordan's answer from this thread

This can be fixed by updating to Gradle 5.5

The easiest way to do this is to update the wrapper in use:

• Open gradle/gradle-wrapper.properties

• Find the line that looks like

distributionUrl=https\://services.gradle.org/distributions/gradle-5.X.X-all.zip

• Change the version to 5.5-all.zip

Then try running the build again.

This is a preferable answer in most use cases, because it allows you to decouple execution of the software from direct knowledge of the server platform, which keeps your code much more portable. If you are doing a lot of cron/cgi, this may not help directly, but it can be set into a config at web runtime that the cron/cgi scripts pull from to keep the log location consistent in that case.

You can get the current log file assigned natively to php on any platform at runtime by using:

ini_get('error_log');

This returns the value distributed directly to the php binary by the webserver, which is what you want in 90% of use cases (with the glaring exception being cgi). Cgi will often log to this same location as the http webserver client, but not always.

You will also want to check that it is writeable before committing anything to it to avoid errors. The conf file that defines it's location (typically either apache.conf globally or vhosts.conf on a per-domain basis), but the conf does not ensure that file permissions allow write access at runtime.

Explaining the practical use for a closure in JavaScript

When we create a function inside another function, we are creating a closure. Closures are powerful because they are capable of reading and manipulating the data of its outer functions. Whenever a function is invoked, a new scope is created for that call. The local variable declared inside the function belong to that scope and they can only be accessed from that function. When the function has finished the execution, the scope is usually destroyed.

A simple example of such function is this:

function buildName(name) {
    const greeting = "Hello, " + name;
    return greeting;
}

In above example, the function buildName() declares a local variable greeting and returns it. Every function call creates a new scope with a new local variable. After the function is done executing, we have no way to refer to that scope again, so it’s garbage collected.

But how about when we have a link to that scope?

Let’s look at the next function:

function buildName(name) {
    const greeting = "Hello, " + name + " Welcome ";
    const sayName = function() {
        console.log(greeting);
    };
    return sayName;
}

const sayMyName = buildName("Mandeep");
sayMyName();  // Hello, Mandeep Welcome

The function sayName() from this example is a closure. The sayName() function has its own local scope (with variable welcome) and has also access to the outer (enclosing) function’s scope. In this case, the variable greeting from buildName().

After the execution of buildName is done, the scope is not destroyed in this case. The sayMyName() function still has access to it, so it won’t be garbage collected. However, there is no other way of accessing data from the outer scope except the closure. The closure serves as the gateway between the global context and the outer scope.

Federico Zancan's answer is correct but you don't have to give your script an ID and eval all your script. Just eval your function name and it can be called.

To achieve this in our project, we wrote a proxy function to call the function returned inside the Ajax response.

function FunctionProxy(functionName){
    var func = eval(functionName);
    func();
}

field.setInputType(InputType.TYPE_CLASS_TEXT);

Try the following:

int myIndex = MyDataGrid.SelectedIndex;

This will give the index of the row which is currently selected.

Hope this helps

TensorFlow 2.x

Eager Execution is enabled by default, so just call .numpy() on the Tensor object.

import tensorflow as tf

a = tf.constant([[1, 2], [3, 4]])                 
b = tf.add(a, 1)

a.numpy()
# array([[1, 2],
#        [3, 4]], dtype=int32)

b.numpy()
# array([[2, 3],
#        [4, 5]], dtype=int32)

tf.multiply(a, b).numpy()
# array([[ 2,  6],
#        [12, 20]], dtype=int32)

See NumPy Compatibility for more. It is worth noting (from the docs),

Numpy array may share memory with the Tensor object. Any changes to one may be reflected in the other.

Bold emphasis mine. A copy may or may not be returned, and this is an implementation detail based on whether the data is in CPU or GPU (in the latter case, a copy has to be made from GPU to host memory).

But why am I getting AttributeError: 'Tensor' object has no attribute 'numpy'?.
A lot of folks have commented about this issue, there are a couple of possible reasons:

• TF 2.0 is not correctly installed (in which case, try re-installing), or
• TF 2.0 is installed, but eager execution is disabled for some reason. In such cases, call tf.compat.v1.enable_eager_execution() to enable it, or see below.

If Eager Execution is disabled, you can build a graph and then run it through tf.compat.v1.Session:

a = tf.constant([[1, 2], [3, 4]])                 
b = tf.add(a, 1)
out = tf.multiply(a, b)

out.eval(session=tf.compat.v1.Session())    
# array([[ 2,  6],
#        [12, 20]], dtype=int32)

See also TF 2.0 Symbols Map for a mapping of the old API to the new one.

Follow the below steps to consume RestFul in android.

Step1

Create a android blank project.

Step2

Need internet access permission. write the below code in AndroidManifest.xml file.

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

Step3

Need RestFul url which is running in another server or same machine.

Step4

Make a RestFul Client which will extends AsyncTask. See RestFulPost.java.

Step5

Make DTO class for RestFull Request and Response.

in devices which has Android 4.3 and above you should follow these steps:

How to enable Developer Options:

Launch Settings menu.
Find the open the ‘About Device’ menu.
Scroll down to ‘Build Number’.
Next, tap on the ‘build number’ section seven times.
After the seventh tap you will be told that you are now a developer.
Go back to Settings menu and the Developer Options menu will now be displayed.

In order to enable the USB Debugging you will simply need to open Developer Options, scroll down and tick the box that says ‘USB Debugging’. That’s it.

System.currentTimeMillis() is not safe for elapsed time because this method is sensitive to the system realtime clock changes of the system. You should use System.nanoTime. Please refer to Java System help:

About nanoTime method:

.. This method provides nanosecond precision, but not necessarily nanosecond resolution (that is, how frequently the value changes) - no guarantees are made except that the resolution is at least as good as that of currentTimeMillis()..

If you use System.currentTimeMillis() your elapsed time can be negative (Back <-- to the future)

I use latest CSS and "+" didn't work for me so I end up with

:first-child

According to this, you need to assign a height to the element in which the div is contained in order for 100% height to work. Does that work for you?

Combining the above answers i find a simply solution that probably will help you too:

<button type="submit" onclick="location.href = 'your_link';">Login</button>

by just adding inline JS code you can transform a button in a link and keeping his design.

You could just use REPLACE:

UPDATE myTable SET emailCol = REPLACE(emailCol, '.com', '.org')`.

But take into account an email address such as [email protected] will be updated to [email protected].

If you want to be on a safer side, you should check for the last 4 characters using RIGHT, and append .org to the SUBSTRING manually instead. Notice the usage of UPPER to make the search for the .com ending case insensitive.

UPDATE myTable 
SET emailCol = SUBSTRING(emailCol, 1, LEN(emailCol)-4) + '.org'
WHERE UPPER(RIGHT(emailCol,4)) = '.COM';

See it working in this SQLFiddle.

The solution...services and rxjs...event emitters and property binding both use rxjs..you are better of implementing it your self, more control, easier to debug. Remember that event emitters are using rxjs. Simply, create a service and within an observable, have each component subscribe to tha observer and either pass new value or cosume value as needed

As it seems impossible to filter the XPath message data (it isn't in the XML to filter), you can also use powershell to search:

Get-WinEvent -LogName System | Where-Object {$_.Message -like "*recycle*"}

From this, I can see that the event Id for recycling seems to be 5074, so you can filter on this as well. I hope this helps someone as this information seemed to take a lot longer than expected to work out.

This along with @BlackHawkDesign comment should help you find what you need.

I had the same issue. Maybe interesting to mention is that you have to configure in which cases the app pool recycle event is logged. By default it's in a couple of cases, not all of them. You can do that in IIS > app pools > select the app pool > advanced settings > expand generate recycle event log entry – BlackHawkDesign Jan 14 '15 at 10:00

I've used sliksvn and it works great for me

Use the formatting options available to you, use the Decimal format string. It is far more flexible and requires little to no maintenance compared to direct string manipulation.

To get the string representation using at least 4 digits:

int length = 4;
int number = 50;
string asString = number.ToString("D" + length); //"0050"

If you open your module settings (F4) you can nominate which paths contain 'source'. Intellij will then mark these directories in blue and allow you to add classes etc.

In a similar fashion you can highlight test directories for unit tests.

simple way can be -

just href="javascript:location.reload(true);

your answer is

location.reload(true);

Thanks

You could also override ArrayList to insert nulls between your size and the element you want to add.

import java.util.ArrayList;


public class ArrayListAnySize<E> extends ArrayList<E>{
    @Override
    public void add(int index, E element){
        if(index >= 0 && index <= size()){
            super.add(index, element);
            return;
        }
        int insertNulls = index - size();
        for(int i = 0; i < insertNulls; i++){
            super.add(null);
        }
        super.add(element);
    }
}

Then you can add at any point in the ArrayList. For example, this main method:

public static void main(String[] args){
    ArrayListAnySize<String> a = new ArrayListAnySize<>();
    a.add("zero");
    a.add("one");
    a.add("two");
    a.add(5,"five");
    for(int i = 0; i < a.size(); i++){
        System.out.println(i+": "+a.get(i));
    }
}   

yields this result from the console:

0: zero

1: one

2: two

3: null

4: null

5: five

I've found this solution by googling. I have just had this problem and it solved it.

My mistake was to put a project in other location out of the workspace, and share this workspace between several computers, where the paths difer. I learned that, when a project is out of workspace, its location is saved in workspace/.metadata/.plugins/org.eclipse.core.resources/.projects/PROJECTNAME/.location

Deleting .location and reimporting the project into workspace solved the issue. Hope this helps.

Put your style.css directly into the webapp/css folder, not into the WEB-INF folder.

Then add the following code into your spring-dispatcher-servlet.xml

<mvc:resources mapping="/css/**" location="/css/" />

and then add following code into your jsp page

<link rel="stylesheet" type="text/css" href="css/style.css"/>

I hope it will work.

  double latRad(double lat) {
    final double sin = math.sin(lat * math.pi / 180);
    final double radX2 = math.log((1 + sin) / (1 - sin)) / 2;
    return math.max(math.min(radX2, math.pi), -math.pi) / 2;
  }

  double getMapBoundZoom(LatLngBounds bounds, double mapWidth, double mapHeight) {
    final LatLng northEast = bounds.northEast;
    final LatLng southWest = bounds.southWest;

    final double latFraction = (latRad(northEast.latitude) - latRad(southWest.latitude)) / math.pi;

    final double lngDiff = northEast.longitude - southWest.longitude;
    final double lngFraction = ((lngDiff < 0) ? (lngDiff + 360) : lngDiff) / 360;

    final double latZoom = (math.log(mapHeight / 256 / latFraction) / math.ln2).floorToDouble();
    final double lngZoom = (math.log(mapWidth / 256 / lngFraction) / math.ln2).floorToDouble();

    return math.min(latZoom, lngZoom);
  }

If your emulators were working and now they aren't due to Avast...

Avast no longer has the option for "Enable Hardware-assisted Virtualization" in Troubleshooting. (it's now March 2017)

Avast captures "emulator.exe", which disables emulators,and stows it in the Virus chest. Open the chest, "Restore and add to exclusions" and your emulator works again...

Inserting data into a pandas dataframe and providing column name.

import pandas as pd
df = pd.DataFrame([['A','C','A','B','C','A','B','B','A','A'], ['ONE','TWO','ONE','ONE','ONE','TWO','ONE','TWO','ONE','THREE']]).T
df.columns = [['Alphabet','Words']]
print(df)   #printing dataframe.

This is our printed data:

For making a group of dataframe in pandas and counter,
You need to provide one more column which counts the grouping, let's call that column as, "COUNTER" in dataframe.

Like this:

df['COUNTER'] =1       #initially, set that counter to 1.
group_data = df.groupby(['Alphabet','Words'])['COUNTER'].sum() #sum function
print(group_data)

OUTPUT:

It depends on where you want to use those.

Just type java -version in your console.

If a 64 bit version is running, you'll get a message like:

java version "1.6.0_18"
Java(TM) SE Runtime Environment (build 1.6.0_18-b07)
Java HotSpot(TM) 64-Bit Server VM (build 16.0-b13, mixed mode)

A 32 bit version will show something similar to:

java version "1.6.0_41"
Java(TM) SE Runtime Environment (build 1.6.0_41-b02)
Java HotSpot(TM) Client VM (build 20.14-b01, mixed mode, sharing)

Note Client instead of 64-Bit Server in the third line. The Client/Server part is irrelevant, it's the absence of the 64-Bit that matters.

If multiple Java versions are installed on your system, navigate to the /bin folder of the Java version you want to check, and type java -version there.

During installation of your program, just prompt the user and have a DOS Batch script or a Bash shell script download and copy the JCE into the proper system location.

I used to have to do this for a server webservice and instead of a formal installer, I just provided scripts to setup the app before the user could run it. You can make the app un-runnable until they run the setup script. You could also make the app complain that the JCE is missing and then ask to download and restart the app?

jQuery UI has a :data() selector which can also be used. It has been around since Version 1.7.0 it seems.

You can use it like this:

Get all elements with a data-company attribute

var companyElements = $("ul:data(group) li:data(company)");

Get all elements where data-company equals Microsoft

var microsoft = $("ul:data(group) li:data(company)")
                    .filter(function () {
                        return $(this).data("company") == "Microsoft";
                    });

Get all elements where data-company does not equal Microsoft

var notMicrosoft = $("ul:data(group) li:data(company)")
                       .filter(function () {
                           return $(this).data("company") != "Microsoft";
                       });

etc...

One caveat of the new :data() selector is that you must set the data value by code for it to be selected. This means that for the above to work, defining the data in HTML is not enough. You must first do this:

$("li").first().data("company", "Microsoft");

This is fine for single page applications where you are likely to use $(...).data("datakey", "value") in this or similar ways.

For c++ you should use g++.

It's the same compiler (e.g. the GNU compiler collection). GCC or G++ just choose a different front-end with different default options.

In a nutshell: if you use g++ the frontend will tell the linker that you may want to link with the C++ standard libraries. The gcc frontend won't do that (also it could link with them if you pass the right command line options).

My error was very simple: the text file containing the data had some space (so not visible) character on the last line.

As an output of grep, I had 45  instead of just 45. 

In addition to checking your table setup to confirm that the field is set to NOT NULL with a default of CURRENT_TIMESTAMP, you can insert date/time values from PHP by writing them in a string format compatible with MySQL.

 $timestamp = date("Y-m-d H:i:s");

This will give you the current date and time in a string format that you can insert into MySQL.

If you know the folder you want to navigate to, find the index of it then substring.

            var ind = Directory.GetCurrentDirectory().ToString().IndexOf("Folderame");

            string productFolder = Directory.GetCurrentDirectory().ToString().Substring(0, ind);

You can try

sed 's:\\:\/:g'`

The first \ is to insert an input, the second \ will be the one you want to substitute.

So it is 's ":" First Slash "\" second slash "\" ":" "\" to insert input "/" as the new slash that will be presented ":" g'

\\ \/ 

And that's it. It will work.

Following command can be used to delete all the existing messages in kafka topic:

kafka-delete-records --bootstrap-server <kafka_server:port> --offset-json-file delete.json

The structure of the delete.json file should be following:

{ "partitions": [ { "topic": "foo", "partition": 1, "offset": -1 } ], "version": 1 }

where offset :-1 will delete all the records (This command has been tested with kafka 2.0.1

Setting single environment variables (based on answer by Edward Campbell):

public static void setEnv(String key, String value) {
    try {
        Map<String, String> env = System.getenv();
        Class<?> cl = env.getClass();
        Field field = cl.getDeclaredField("m");
        field.setAccessible(true);
        Map<String, String> writableEnv = (Map<String, String>) field.get(env);
        writableEnv.put(key, value);
    } catch (Exception e) {
        throw new IllegalStateException("Failed to set environment variable", e);
    }
}

Usage:

First, put the method in any class you want, e.g. SystemUtil. Then call it statically:

SystemUtil.setEnv("SHELL", "/bin/bash");

If you call System.getenv("SHELL") after this, you'll get "/bin/bash" back.

You are expecting that your int type is 16 bit wide, in which case you'd indeed get a negative value. But most likely it's 32 bits wide, so a signed int can represent 65529 just fine. You can check this by printing sizeof(int).

Taken from: http://www.w3.org/Style/Examples/007/units:

The em is simply the font size. In an element with a 2in font, 1em thus means 2in. Expressing sizes, such as margins and paddings, in em means they are related to the font size, and if the user has a big font (e.g., on a big screen) or a small font (e.g., on a handheld device), the sizes will be in proportion. Declarations such as 'text-indent: 1.5em' and 'margin: 1em' are extremely common in CSS.

em is basically CSS property for font sizes.

You are mixing the 2 different CASE syntaxes inappropriately.

Use this style (Searched)

  CASE  
  WHEN u.nnmu ='0' THEN mu.naziv_mesta
  WHEN u.nnmu ='1' THEN m.naziv_mesta
 ELSE 'GRESKA'
 END as mesto_utovara,

Or this style (Simple)

  CASE u.nnmu 
  WHEN '0' THEN mu.naziv_mesta
  WHEN '1' THEN m.naziv_mesta
 ELSE 'GRESKA'
 END as mesto_utovara,

Not This (Simple but with boolean search predicates)

  CASE u.nnmu 
  WHEN u.nnmu ='0' THEN mu.naziv_mesta
  WHEN u.nnmu ='1' THEN m.naziv_mesta
 ELSE 'GRESKA'

In MySQL this will end up testing whether u.nnmu is equal to the value of the boolean expression u.nnmu ='0' itself. Regardless of whether u.nnmu is 1 or 0 the result of the case expression itself will be 1

For example if nmu = '0' then (nnmu ='0') evaluates as true (1) and (nnmu ='1') evaluates as false (0). Substituting these into the case expression gives

 SELECT CASE  '0'
  WHEN 1 THEN '0'
  WHEN 0 THEN '1'
 ELSE 'GRESKA'
 END as mesto_utovara

if nmu = '1' then (nnmu ='0') evaluates as false (0) and (nnmu ='1') evaluates as true (1). Substituting these into the case expression gives

 SELECT CASE  '1'
  WHEN 0 THEN '0'
  WHEN 1 THEN '1'
 ELSE 'GRESKA'
 END as mesto_utovara

They are extension methods. Welcome to a whole new fluent world. :)

I got this error but it is resolved interesting. As first, i got this error at api level 17. When i call a thread (AsyncTask or others) without progress dialog then i call an other thread method again using progress dialog, i got that crash and the reason is about usage of progress dialog.

In my case, there are two results that;

• I took show(); method of progress dialog before first thread starts then i took dismiss(); method of progress dialog before last thread ends.

So :

ProgresDialog progressDialog = new ...

//configure progressDialog 

progressDialog.show();

start firstThread {
...
}

...

start lastThread {
...
} 

//be sure to finish threads

progressDialog.dismiss();

• This is so strange but that error has an ability about destroy itself at least for me :)

If you have robocopy,

robocopy C:\Folder1 D:\Folder2 /COPYALL /E

otherwise,

xcopy /e /v C:\Folder1 D:\Folder2

Very simple. Just cast your char as an int.

char character = 'a';    
int ascii = (int) character;

In your case, you need to get the specific Character from the String first and then cast it.

char character = name.charAt(0); // This gives the character 'a'
int ascii = (int) character; // ascii is now 97.

Though cast is not required explicitly, but its improves readability.

int ascii = character; // Even this will do the trick.

Within your component, you can define an array of number (ES6) as described below:

export class SampleComponent {
  constructor() {
    this.numbers = Array(5).fill(0).map((x,i)=>i);
  }
}

See this link for the array creation: Tersest way to create an array of integers from 1..20 in JavaScript.

You can then iterate over this array with ngFor:

@View({
  template: `
    <ul>
      <li *ngFor="let number of numbers">{{number}}</li>
    </ul>
  `
})
export class SampleComponent {
  (...)
}

Or shortly:

@View({
  template: `
    <ul>
      <li *ngFor="let number of [0,1,2,3,4]">{{number}}</li>
    </ul>
  `
})
export class SampleComponent {
  (...)
}

Hope it helps you, Thierry

Edit: Fixed the fill statement and template syntax.

I upgraded VS2017 from version 15.2 to 15.8. With version 15.8 here's what happened:

Project -> Properties -> General -> Windows SDK Version -> select 10.0.15063.0 no longer worked for me! I had to change it to 10.0.17134.0 and then everything built again. After the upgrade and without making this change, I was getting the same header file errors.

I would have submitted this as a comment on one of the other answers but I don't have enough reputation yet.

android:editable="false" should work, but it is deprecated, you should be using android:inputType="none" instead.

Alternatively, if you want to do it in the code you could do this :

EditText mEdit = (EditText) findViewById(R.id.yourid);
mEdit.setEnabled(false);

This is also a viable alternative :

EditText mEdit = (EditText) findViewById(R.id.yourid);
mEdit.setKeyListener(null);

If you're going to make your EditText non-editable, may I suggest using the TextView widget instead of the EditText, since using a EditText seems kind of pointless in that case.

EDIT: Altered some information since I've found that android:editable is deprecated, and you should use android:inputType="none", but there is a bug about it on android code; So please check this.

I wrote up some code that will sort a table by a row, assuming only one <tbody> and cells don't have a colspan.

function sortTable(table, col, reverse) {
    var tb = table.tBodies[0], // use `<tbody>` to ignore `<thead>` and `<tfoot>` rows
        tr = Array.prototype.slice.call(tb.rows, 0), // put rows into array
        i;
    reverse = -((+reverse) || -1);
    tr = tr.sort(function (a, b) { // sort rows
        return reverse // `-1 *` if want opposite order
            * (a.cells[col].textContent.trim() // using `.textContent.trim()` for test
                .localeCompare(b.cells[col].textContent.trim())
               );
    });
    for(i = 0; i < tr.length; ++i) tb.appendChild(tr[i]); // append each row in order
}
// sortTable(tableNode, columId, false);

If you don't want to make the assumptions above, you'd need to consider how you want to behave in each circumstance. (e.g. put everything into one <tbody> or add up all the preceeding colspan values, etc.)

You could then attach this to each of your tables, e.g. assuming titles are in <thead>

function makeSortable(table) {
    var th = table.tHead, i;
    th && (th = th.rows[0]) && (th = th.cells);
    if (th) i = th.length;
    else return; // if no `<thead>` then do nothing
    while (--i >= 0) (function (i) {
        var dir = 1;
        th[i].addEventListener('click', function () {sortTable(table, i, (dir = 1 - dir))});
    }(i));
}

function makeAllSortable(parent) {
    parent = parent || document.body;
    var t = parent.getElementsByTagName('table'), i = t.length;
    while (--i >= 0) makeSortable(t[i]);
}

and then invoking makeAllSortable onload.

You are correct that ** is the power function.

^ is bitwise XOR.

% is indeed the modulus operation, but note that for positive numbers, x % m = x whenever m > x. This follows from the definition of modulus. (Additionally, Python specifies x % m to have the sign of m.)

// is a division operation that returns an integer by discarding the remainder. This is the standard form of division using the / in most programming languages. However, Python 3 changed the behavior of / to perform floating-point division even if the arguments are integers. The // operator was introduced in Python 2.6 and Python 3 to provide an integer-division operator that would behave consistently between Python 2 and Python 3. This means:

| context                                | `/` behavior   | `//` behavior |
---------------------------------------------------------------------------
| floating-point arguments, Python 2 & 3 | float division | int divison   |
---------------------------------------------------------------------------
| integer arguments, python 2            | int division   | int division  |
---------------------------------------------------------------------------
| integer arguments, python 3            | float division | int division  |

For more details, see this question: Division in Python 2.7. and 3.3

It appears as though you need to explicitly set a font, and change the line-height and height as needed. Assuming 'Times New Roman' is your browser's default font:

span {_x000D_
  display: inline-block;_x000D_
  font-size: 50px;_x000D_
  background-color: green;_x000D_
  /*new:*/_x000D_
  font-family: 'Times New Roman';_x000D_
  line-height: 34px;_x000D_

}

<link href='http://fonts.googleapis.com/css?family=Tinos' rel='stylesheet' type='text/css'>_x000D_
<span>_x000D_

You seem to have used some [Authorize] attribute on your Web API controller action and I don't see how this is relevant to your question.

So, let's get into practice. Here's a how a trivial Web API controller might look like:

public class TestController : ApiController
{
    public string Post([FromBody] string value)
    {
        return value;
    }
}

and a consumer for that matter:

class Program
{
    static void Main()
    {
        using (var client = new WebClient())
        {
            client.Headers[HttpRequestHeader.ContentType] = "application/x-www-form-urlencoded";
            var data = "=Short test...";
            var result = client.UploadString("http://localhost:52996/api/test", "POST", data);
            Console.WriteLine(result);
        }
    }
}

You will undoubtedly notice the [FromBody] decoration of the Web API controller attribute as well as the = prefix of the POST data om the client side. I would recommend you reading about how does the Web API does parameter binding to better understand the concepts.

As far as the [Authorize] attribute is concerned, this could be used to protect some actions on your server from being accessible only to authenticated users. Actually it is pretty unclear what you are trying to achieve here.You should have made this more clear in your question by the way. Are you are trying to understand how parameter bind works in ASP.NET Web API (please read the article I've linked to if this is your goal) or are attempting to do some authentication and/or authorization? If the second is your case you might find the following post that I wrote on this topic interesting to get you started.

And if after reading the materials I've linked to, you are like me and say to yourself, WTF man, all I need to do is POST a string to a server side endpoint and I need to do all of this? No way. Then checkout ServiceStack. You will have a good base for comparison with Web API. I don't know what the dudes at Microsoft were thinking about when designing the Web API, but come on, seriously, we should have separate base controllers for our HTML (think Razor) and REST stuff? This cannot be serious.

MongoDB needs data directory to store data. Default path is /data/db

When you start MongoDB engine, it searches this directory which is missing in your case. Solution is create this directory and assign rwx permission to user.

If you want to change the path of your data directory then you should specify it while starting mongod server like,

mongod --dbpath /data/<path> --port <port no> 

This should help you start your mongod server with custom path and port.

I used following command in MySQL command-line to restore a MySQL database which size more than 7GB, and it works.

set global max_allowed_packet=268435456;

Run:

go mod init yellow

Then create a file yellow.go:

package yellow

func Mix(s string) string {
   return s + "Yellow"
}

Then create a file orange/orange.go:

package main
import "yellow"

func main() {
   s := yellow.Mix("Red")
   println(s)
}

Then build:

go build

Should just be something like:

// Gets the number of elements with class yourClass
var numItems = $('.yourclass').length

As a side-note, it is often beneficial to check the length property before chaining a lot of functions calls on a jQuery object, to ensure that we actually have some work to perform. See below:

var $items = $('.myclass');
// Ensure we have at least one element in $items before setting up animations
// and other resource intensive tasks.
if($items.length)
{
  $items.animate(/* */)
    // It might also be appropriate to check that we have 2 or more
    // elements returned by the filter-call before animating this subset of 
    // items.
    .filter(':odd')
      .animate(/* */)
      .end()
    .promise()
    .then(function () { 
       $items.addClass('all-done');
    });
}

Can't you just say a never ending loop, cookie expires as current date + 1 so it never hits the date it's supposed to expire on because it's always tomorrow? A bit overkill but just saying.

I had the same requirement and I have done this in following way.You also can try out this..

Use loadData method

web.loadData("<p style='text-align:center'><img class='aligncenter size-full wp-image-1607' title='' src="+movImage+" alt='' width='240px' height='180px' /></p><p><center><U><H2>"+movName+"("+movYear+")</H2></U></center></p><p><strong>Director : </strong>"+movDirector+"</p><p><strong>Producer : </strong>"+movProducer+"</p><p><strong>Character : </strong>"+movActedAs+"</p><p><strong>Summary : </strong>"+movAnecdotes+"</p><p><strong>Synopsis : </strong>"+movSynopsis+"</p>\n","text/html", "UTF-8");

movDirector movProducer like all are my string variable.

In short i retain custom styling for my url.

I recommend looking at docopt as a simple alternative to these others.

docopt is a new project that works by parsing your --help usage message rather than requiring you to implement everything yourself. You just have to put your usage message in the POSIX format.

Knowing the scope of each can make things easier to remember.

process is node's global object, and .cwd() returns where node is running.

__dirname is module's property, and represents the file path of the module. In node, one module resides in one file.

Similarly, __filename is another module's property, which holds the file name of the module.

You can try:

git remote -v

It will print all your remotes' fetch/push URLs.

For a lot of utility-type methods, the apache commons libraries have solid implementations that you can either leverage or get additional insight from. In this case, there is a method for finding the smallest of three doubles available in org.apache.commons.lang.math.NumberUtils. Their implementation is actually nearly identical to your initial thought:

public static double min(double a, double b, double c) {
    return Math.min(Math.min(a, b), c);
}

Big difference, TABLOCK will try to grab "shared" locks, and TABLOCKX exclusive locks.

If you are in a transaction and you grab an exclusive lock on a table, EG:

SELECT 1 FROM TABLE WITH (TABLOCKX)

No other processes will be able to grab any locks on the table, meaning all queries attempting to talk to the table will be blocked until the transaction commits.

TABLOCK only grabs a shared lock, shared locks are released after a statement is executed if your transaction isolation is READ COMMITTED (default). If your isolation level is higher, for example: SERIALIZABLE, shared locks are held until the end of a transaction.

Shared locks are, hmmm, shared. Meaning 2 transactions can both read data from the table at the same time if they both hold a S or IS lock on the table (via TABLOCK). However, if transaction A holds a shared lock on a table, transaction B will not be able to grab an exclusive lock until all shared locks are released. Read about which locks are compatible with which at msdn.

Both hints cause the db to bypass taking more granular locks (like row or page level locks). In principle, more granular locks allow you better concurrency. So for example, one transaction could be updating row 100 in your table and another row 1000, at the same time from two transactions (it gets tricky with page locks, but lets skip that).

In general granular locks is what you want, but sometimes you may want to reduce db concurrency to increase performance of a particular operation and eliminate the chance of deadlocks.

In general you would not use TABLOCK or TABLOCKX unless you absolutely needed it for some edge case.

I use $response->getBody()->getContents() to get JSON from response. Guzzle version 6.3.0.

To be honest, a ternary operator would only make this worse, what i would suggest if making it simpler is what you are aiming at is:

$groups = array(1=>"Player", 2=>"Gamemaster", 3=>"God");
echo($groups[$result->group_id]);

and then a similar one for your vocations

$vocations = array(
  1=>"Sorcerer",
  2=>"Druid",
  3=>"Paladin",
  4=>"Knight",
  ....
);
echo($vocations[$result->vocation]);

With a ternary operator, you would end up with

echo($result->group_id == 1 ? "Player" : ($result->group_id == 2 ? "Gamemaster" : ($result->group_id == 3 ? "God" : "unknown")));

Which as you can tell, only gets more complicated the more you add to it

I haven't done time test with this but it was fun to try. Basically convert two columns to one column of tuples. Now convert that to a dataframe, do 'value_counts()' which finds the unique elements and counts them. Fiddle with zip again and put the columns in order you want. You can probably make the steps more elegant but working with tuples seems more natural to me for this problem

b = pd.DataFrame({'A':['yes','yes','yes','yes','no','no','yes','yes','yes','no'],'B':['yes','no','no','no','yes','yes','no','yes','yes','no']})

b['count'] = pd.Series(zip(*[b.A,b.B]))
df = pd.DataFrame(b['count'].value_counts().reset_index())
df['A'], df['B'] = zip(*df['index'])
df = df.drop(columns='index')[['A','B','count']]

No need to update gradle for making release application in Android studio.If you were eclipse user then it will be so easy for you. If you are new then follow the steps

1: Go to the "Build" at the toolbar section. 2: Choose "Generate Signed APK..." option.

3:fill opened form and go next 4 :if you already have .keystore or .jks then choose that file enter your password and alias name and respective password. 5: Or don't have .keystore or .jks file then click on Create new... button as shown on pic 1 then fill the form.

Above process was to make build manually. If You want android studio to automatically Signing Your App

In Android Studio, you can configure your project to sign your release APK automatically during the build process:

On the project browser, right click on your app and select Open Module Settings. On the Project Structure window, select your app's module under Modules. Click on the Signing tab. Select your keystore file, enter a name for this signing configuration (as you may create more than one), and enter the required information. Figure 4. Create a signing configuration in Android Studio.

Click on the Build Types tab. Select the release build. Under Signing Config, select the signing configuration you just created. Figure 5. Select a signing configuration in Android Studio.

4:Most Important thing that make debuggable=false at gradle.

    buildTypes {
        release {
           minifyEnabled false

If you want it to obey your width and height properly though enclose your segmentedControl in a UIView first as the tableView likes to mangle your view a bit to fit the width.

While you are in it, I suggest to remember some key facts about compareTo() methods

1. CompareTo must be in consistent with equals method e.g. if two objects are equal via equals() , there compareTo() must return zero otherwise if those objects are stored in SortedSet or SortedMap they will not behave properly.

2. CompareTo() must throw NullPointerException if current object get compared to null object as opposed to equals() which return false on such scenario.

Take a look here: http://longgoldenears.blogspot.com/2007/09/triple-equals-in-javascript.html

The 3 equal signs mean "equality without type coercion". Using the triple equals, the values must be equal in type as well.

0 == false   // true
0 === false  // false, because they are of a different type
1 == "1"     // true, automatic type conversion for value only
1 === "1"    // false, because they are of a different type
null == undefined // true
null === undefined // false
'0' == false // true
'0' === false // false

In my case I needed a logging module that catches the output from the background applications and augments it(adding time-stamps, colors, etc.).

I ended up with a background thread that does the actual I/O. Following code is only for POSIX platforms. I stripped non-essential parts.

If someone is going to use this beast for long runs consider managing open descriptors. In my case it was not a big problem.

Why dont you take the string and split it

Example on the url

var url = "http://www.youtube.com/watch?p=DB852818BF378DAC&v=1q-k-uN73Gk"

you can do a split as

var params = url.split("?")[1].split("&");

You will get array of strings with params as name value pairs with "=" as the delimiter.

ViewState getters can be one-liners.

Using a default value:

public string Caption
{
    get { return (string) (ViewState["Caption"] ?? "Foo"); }
    set { ViewState["Caption"] = value; }
}

public int Index
{
    get { return (int) (ViewState["Index"] ?? 0); }
    set { ViewState["Index"] = value; }
}

Using null as the default:

public string Caption
{
    get { return (string) ViewState["Caption"]; }
    set { ViewState["Caption"] = value; }
}

public int? Index
{
    get { return (int?) ViewState["Index"]; }
    set { ViewState["Index"] = value; }
}

This works for anything backed by a dictionary.

The 'Z' is what adds the timezone info. As for output UTC, that seems to be the subject of some confusion -- people seem to gravitate toward moment.js.

Borrowing from this answer, you could do something like this without moment.js:

controller

var app1 = angular.module('app1',[]);

app1.controller('ctrl',['$scope',function($scope){

  var toUTCDate = function(date){
    var _utc = new Date(date.getUTCFullYear(), date.getUTCMonth(), date.getUTCDate(),  date.getUTCHours(), date.getUTCMinutes(), date.getUTCSeconds());
    return _utc;
  };

  var millisToUTCDate = function(millis){
    return toUTCDate(new Date(millis));
  };

    $scope.toUTCDate = toUTCDate;
    $scope.millisToUTCDate = millisToUTCDate;

  }]);

template

<html ng-app="app1">

  <head>
    <script data-require="angular.js@*" data-semver="1.2.12" src="http://code.angularjs.org/1.2.12/angular.js"></script>
    <link rel="stylesheet" href="style.css" />
    <script src="script.js"></script>
  </head>

  <body>
    <div ng-controller="ctrl">
      <div>
      utc {{millisToUTCDate(1400167800) | date:'dd-M-yyyy H:mm'}}
      </div>
      <div>
      local {{1400167800 | date:'dd-M-yyyy H:mm'}}
      </div>
    </div>
  </body>

</html>

here's plunker to play with it

See also this and this.

Also note that with this method, if you use the 'Z' from Angular's date filter, it seems it will still print your local timezone offset.

You should try something like this

    <Button
    android:id="@+id/imageButton1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/qrcode"/>

the android:background="@drawable/qrcode" will do it

BufferedWriter is more efficient if you

• have multiple writes between flush/close
• the writes are small compared with the buffer size.

In your example, you have only one write, so the BufferedWriter just add overhead you don't need.

so does that mean the first example writes the characters one by one and the second first buffers it to the memory and writes it once

In both cases, the string is written at once.

If you use just FileWriter your write(String) calls

 public void write(String str, int off, int len) 
        // some code
        str.getChars(off, (off + len), cbuf, 0);
        write(cbuf, 0, len);
 }

This makes one system call, per call to write(String).

Where BufferedWriter improves efficiency is in multiple small writes.

for(int i = 0; i < 100; i++) {
    writer.write("foorbar");
    writer.write(NEW_LINE);
}
writer.close();

Without a BufferedWriter this could make 200 (2 * 100) system calls and writes to disk which is inefficient. With a BufferedWriter, these can all be buffered together and as the default buffer size is 8192 characters this become just 1 system call to write.

Try using setAttribute instead:

document.getElementById('img')
    .setAttribute(
        'src', 'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg=='
    );

Real answer: (And make sure you remove the line-breaks in the base64.)

Currently, Macports has many more packages (~18.6 K) than there are Homebrew formulae (~3.1K), owing to its maturity. Homebrew is slowly catching up though.

Macport packages tend to be maintained by a single person.

Macports can keep multiple versions of packages around, and you can enable or disable them to test things out. Sometimes this list can get corrupted and you have to manually edit it to get things back in order, although this is not too hard.

Both package managers will ask to be regularly updated. This can take some time.

Note: you can have both package managers on your system! It is not one or the other. Brew might complain but Macports won't.

Also, if you are dealing with python or ruby packages, use a virtual environment wherever possible.

Using symfony 2.3 with php 5.5 and using the built in server with

app/console server:run

which should output something like:

Server running on http://127.0.0.1:8000
Quit the server with CONTROL-C.

then go to http://127.0.0.1:8000/app_dev.php/app/example

this should give you the default, which you can also find the default route by viewing src/AppBundle/Controller/DefaultController.php

Since not all datetime.datetime instances have a microsecond component (i.e. when it is zero), you can partition the string on a "." and take only the first item, which will always work:

unicode(datetime.datetime.now()).partition('.')[0]

In Swift 4.2 and Xcode 10.1

let language = NSLocale.preferredLanguages[0]
print(language)//en

You can use sp_lock (and sp_lock2), but in SQL Server 2005 onwards this is being deprecated in favour of querying sys.dm_tran_locks:

select  
    object_name(p.object_id) as TableName, 
    resource_type, resource_description
from
    sys.dm_tran_locks l
    join sys.partitions p on l.resource_associated_entity_id = p.hobt_id

With Java 1.8 there is a new StringJoiner class - so no need for Guava or Apache Commons:

String str = new StringJoiner(",").add("a").add("b").add("c").toString();

Or using a collection directly with the new stream api:

String str = Arrays.asList("a", "b", "c").stream().collect(Collectors.joining(","));

simply used the + operator. Javascript concats strings with +

If you remove directives attribute it should work.

@Component({
    selector: 'parent',
    template: `
            <h1>Parent Component</h1>
            <child></child>
        `
    })
    export class ParentComponent{}


@Component({
    selector: 'child',    
    template: `
            <h4>Child Component</h4>
        `
    })
    export class ChildComponent{}

Directives are like components but they are used in attributes. They also have a declarator @Directive. You can read more about directives Structural Directives and Attribute Directives.

There are two other kinds of Angular directives, described extensively elsewhere: (1) components and (2) attribute directives.

A component manages a region of HTML in the manner of a native HTML element. Technically it's a directive with a template.

Also if you are open the glossary you can find that components are also directives.

Directives fall into one of the following categories:

• Components combine application logic with an HTML template to render application views. Components are usually represented as HTML elements. They are the building blocks of an Angular application.

• Attribute directives can listen to and modify the behavior of other HTML elements, attributes, properties, and components. They are usually represented as HTML attributes, hence the name.

• Structural directives are responsible for shaping or reshaping HTML layout, typically by adding, removing, or manipulating elements and their children.

The difference that components have a template. See Angular Architecture overview.

A directive is a class with a @Directive decorator. A component is a directive-with-a-template; a @Component decorator is actually a @Directive decorator extended with template-oriented features.

The @Component metadata doesn't have directives attribute. See Component decorator.

Here are the primary differences:

Services

Syntax: module.service( 'serviceName', function );

Result: When declaring serviceName as an injectable argument you will be provided with the instance of a function passed to module.service.

Usage: Could be useful for sharing utility functions that are useful to invoke by simply appending () to the injected function reference. Could also be run with injectedArg.call( this ) or similar.

Factories

Syntax: module.factory( 'factoryName', function );

Result: When declaring factoryName as an injectable argument you will be provided the value that is returned by invoking the function reference passed to module.factory.

Usage: Could be useful for returning a 'class' function that can then be new'ed to create instances.

Also check AngularJS documentation and similar question on stackoverflow confused about service vs factory.

Here is example using services and factory. Read more about AngularJS service vs factory.

I added

config.EnableCors(new EnableCorsAttribute(Properties.Settings.Default.Cors, "", ""))

as well as

app.UseCors(CorsOptions.AllowAll);

on the server. This results in two header entries. Just use the latter one and it works.

Chain selectors are not limited just to classes, you can do it for both classes and ids.

Classes

.classA.classB {
/*style here*/
}

Class & Id

.classA#idB {
/*style here*/
}

Id & Id

#idA#idB {
/*style here*/
}

All good current browsers support this except IE 6, it selects based on the last selector in the list. So ".classA.classB" will select based on just ".classB".

For your case

li.left.ui-class-selector {
/*style here*/
}

or

.left.ui-class-selector {
/*style here*/
}

Define "stretch and scale"...

If you've got a bitmap format, it's generally not great (graphically speaking) to stretch it and pull it about. You can use repeatable patterns to give the illusion of the same effect. For instance if you have a gradient that gets lighter towards the bottom of the page, then you would use a graphic that's a single pixel wide and the same height as your container (or preferably larger to account for scaling) and then tile it across the page. Likewise, if the gradient ran across the page, it would be one pixel high and wider than your container and repeated down the page.

Normally to give the illusion of it stretching to fill the container when the container grows or shrinks, you make the image larger than the container. Any overlap would not be displayed outside the bounds of the container.

If you want an effect that relies on something like a box with curved edges, then you would stick the left side of your box to the left side of your container with enough overlap that (within reason) no matter how large the container, it never runs out of background and then you layer an image of the right side of the box with curved edges and position it on the right of the container. Thus as the container shrinks or grows, the curved box effect appears to shrink or grow with it - it doesn't in fact, but it gives the illusion that is what's happening.

As for really making the image shrink and grow with the container, you would need to use some layering tricks to make the image appear to function as a background and some javascript to resize it with the container. There's no current way of doing this with CSS...

If you're using vector graphics, you're way outside my realm of expertise I'm afraid.

Its not especially Hamcrest, but I think it worth to mention here. What I use quite often in Java8 is something like:

assertTrue(myClass.getMyItems().stream().anyMatch(item -> "foo".equals(item.getName())));

(Edited to Rodrigo Manyari's slight improvement. It's a little less verbose. See comments.)

It may be a little bit harder to read, but I like the type and refactoring safety. Its also cool for testing multiple bean properties in combination. e.g. with a java-like && expression in the filter lambda.

When calling Toast inside android fragment:

1. Activity mActivity=this.getActivity();  

2. Toast.makeText(mActivity,"Text you want to display",Toast.LENGTH_SHORT).show();

This works for me.

With Hibernate's NativeQuery, you need to return a ResultList instead of a SingleResult, because Hibernate modifies a native query

INSERT INTO bla (a,b) VALUES (2,3) RETURNING id

like

INSERT INTO bla (a,b) VALUES (2,3) RETURNING id LIMIT 1

if you try to get a single result, which causes most databases (at least PostgreSQL) to throw a syntax error. Afterwards, you may fetch the resulting id from the list (which usually contains exactly one item).

This worked for me:

1. Right click .git folder
2. click get info
3. set permission to your user
4. click the Cog icon and click apply to enclosed items

No more permission denied errors in git.

I recently struggled with this issue for 3 days. How the client is sending the request might not be the cause, the server might not be configured to handle multipart requests. This is what I had to do to get it working:

pom.xml - Added commons-fileupload dependency (download and add the jar to your project if you are not using dependency management such as maven)

<dependency>
  <groupId>commons-fileupload</groupId>
  <artifactId>commons-fileupload</artifactId>
  <version>${commons-version}</version>
</dependency>

web.xml - Add multipart filter and mapping

<filter>
  <filter-name>multipartFilter</filter-name>
  <filter-class>org.springframework.web.multipart.support.MultipartFilter</filter-class>
</filter>
<filter-mapping>
  <filter-name>multipartFilter</filter-name>
  <url-pattern>/springrest/*</url-pattern>
</filter-mapping>

app-context.xml - Add multipart resolver

<beans:bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
    <beans:property name="maxUploadSize">
        <beans:value>10000000</beans:value>
    </beans:property>
</beans:bean>

Your Controller

@RequestMapping(value=Constants.REQUEST_MAPPING_ADD_IMAGE, method = RequestMethod.POST, produces = { "application/json"})
public @ResponseBody boolean saveStationImage(
        @RequestParam(value = Constants.MONGO_STATION_PROFILE_IMAGE_FILE) MultipartFile file,
        @RequestParam(value = Constants.MONGO_STATION_PROFILE_IMAGE_URI) String imageUri, 
        @RequestParam(value = Constants.MONGO_STATION_PROFILE_IMAGE_TYPE) String imageType, 
        @RequestParam(value = Constants.MONGO_FIELD_STATION_ID) String stationId) {
    // Do something with file
    // Return results
}

Your client

public static Boolean updateStationImage(StationImage stationImage) {
    if(stationImage == null) {
        Log.w(TAG + ":updateStationImage", "Station Image object is null, returning.");
        return null;
    }

    Log.d(TAG, "Uploading: " + stationImage.getImageUri());
    try {
        RestTemplate restTemplate = new RestTemplate();
        FormHttpMessageConverter formConverter = new FormHttpMessageConverter();
        formConverter.setCharset(Charset.forName("UTF8"));
        restTemplate.getMessageConverters().add(formConverter);
        restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter());

        restTemplate.setRequestFactory(new HttpComponentsClientHttpRequestFactory());

        HttpHeaders httpHeaders = new HttpHeaders();
        httpHeaders.setAccept(Collections.singletonList(MediaType.parseMediaType("application/json")));

        MultiValueMap<String, Object> parts = new LinkedMultiValueMap<String, Object>();

        parts.add(Constants.STATION_PROFILE_IMAGE_FILE, new FileSystemResource(stationImage.getImageFile()));
        parts.add(Constants.STATION_PROFILE_IMAGE_URI, stationImage.getImageUri());
        parts.add(Constants.STATION_PROFILE_IMAGE_TYPE, stationImage.getImageType());
        parts.add(Constants.FIELD_STATION_ID, stationImage.getStationId());

        return restTemplate.postForObject(Constants.REST_CLIENT_URL_ADD_IMAGE, parts, Boolean.class);
    } catch (Exception e) {
        StringWriter sw = new StringWriter();
        e.printStackTrace(new PrintWriter(sw));

        Log.e(TAG + ":addStationImage", sw.toString());
    }

    return false;
}

That should do the trick. I added as much information as possible because I spent days, piecing together bits and pieces of the full issue, I hope this will help.

You can use the codecs module, like this:

import codecs
BLOCKSIZE = 1048576 # or some other, desired size in bytes
with codecs.open(sourceFileName, "r", "your-source-encoding") as sourceFile:
    with codecs.open(targetFileName, "w", "utf-8") as targetFile:
        while True:
            contents = sourceFile.read(BLOCKSIZE)
            if not contents:
                break
            targetFile.write(contents)

EDIT: added BLOCKSIZE parameter to control file chunk size.

According to http://www.w3schools.com/css/css_align.asp, setting the left and right margins to auto specifies that they should split the available margin equally. The result is a centered element:

margin-left: auto;margin-right: auto;

While I realize this is an older thread, I noticed the if block above is out of place with using:

Following is corrected:

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
    Dim filePath As String =
      String.Format("C:\ErrorLog_{0}.txt", DateTime.Today.ToString("dd-MMM-yyyy"))
    Using writer As New StreamWriter(filePath, True)
        If File.Exists(filePath) Then
            writer.WriteLine("Error Message in  Occured at-- " & DateTime.Now)
        Else
            writer.WriteLine("Start Error Log for today")
        End If
    End Using
End Sub

I dont know about XamGrid but that's what i'll do with a standard wpf DataGrid:

<DataGrid>
    <DataGrid.Columns>
        <DataGridTemplateColumn>
            <DataGridTemplateColumn.CellTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding DataContext.MyProperty, RelativeSource={RelativeSource AncestorType=MyUserControl}}"/>
                </DataTemplate>
            </DataGridTemplateColumn.CellTemplate>
            <DataGridTemplateColumn.CellEditingTemplate>
                <DataTemplate>
                    <TextBox Text="{Binding DataContext.MyProperty, RelativeSource={RelativeSource AncestorType=MyUserControl}}"/>
                </DataTemplate>
            </DataGridTemplateColumn.CellEditingTemplate>
        </DataGridTemplateColumn>
    </DataGrid.Columns>
</DataGrid>

Since the TextBlock and the TextBox specified in the cell templates will be part of the visual tree, you can walk up and find whatever control you need.

I got this same error while installing mitmproxy using pip3. The below command fixed this:

pip3 install --upgrade setuptools

If you would like to support really old browsers you should parse the date string, since using the ISO8601 date format with the Date constructor is not supported pre IE9:

var queryDate = '2009-11-01',
    dateParts = queryDate.match(/(\d+)/g)
    realDate = new Date(dateParts[0], dateParts[1] - 1, dateParts[2]);  
                                    // months are 0-based!
// For >= IE9
var realDate = new Date('2009-11-01');  

$('#datePicker').datepicker({ dateFormat: 'yy-mm-dd' }); // format to show
$('#datePicker').datepicker('setDate', realDate);

Check the above example here.

=ROUND((TODAY()-A1)/365,0) will provide number of years between date in cell A1 and today's date

It's not possible with CSS3. There is a proposed CSS4 selector, $, to do just that, which could look like this (Selecting the li element):

ul $li ul.sub { ... }

See the list of CSS4 Selectors here.

As an alternative, with jQuery, a one-liner you could make use of would be this:

$('ul li:has(ul.sub)').addClass('has_sub');

You could then go ahead and style the li.has_sub in your CSS.

you have already forwarded the response in catch block:

RequestDispatcher dd = request.getRequestDispatcher("error.jsp");

dd.forward(request, response);

so, you can not again call the :

response.sendRedirect("usertaskpage.jsp");

because it is already forwarded (committed).

So what you can do is: keep a string to assign where you need to forward the response.

    String page = "";
    try {

    } catch (Exception e) {
      page = "error.jsp";
    } finally {
      page = "usertaskpage.jsp";
    }

RequestDispatcher dd=request.getRequestDispatcher(page);
dd.forward(request, response);

The easiest way (offering something near what you wrote) is to use Boost.Regex, specifically regex_replace.

std::string has built in find() and replace() methods, but they are more cumbersome to work with as they require dealing with indices and string lengths.

There are two options:

A: You care about retaining array order:

a = append(a[:i], a[i+1:]...)
// or
a = a[:i+copy(a[i:], a[i+1:])]

B: You don't care about retaining order (this is probably faster):

a[i] = a[len(a)-1] // Replace it with the last one. CAREFUL only works if you have enough elements.
a = a[:len(a)-1]   // Chop off the last one.

See the link to see implications re memory leaks if your array is of pointers.

https://github.com/golang/go/wiki/SliceTricks

As previously pointed out almost all of the calls are chainable.

So you could call

when(mock.method()).thenReturn(foo).thenReturn(bar).thenThrow(new Exception("test"));

//OR if you're mocking a void method and/or using spy instead of mock

doReturn(foo).doReturn(bar).doThrow(new Exception("Test").when(mock).method();

More info in Mockito's Documenation.

Basically you should use the java.lang.Package class which use the classloader to give you informations about your classes.

example:

String.class.getPackage().getImplementationVersion();
Package.getPackage(this).getImplementationVersion();
Package.getPackage("java.lang.String").getImplementationVersion();

I think logback is known to use this feature to trace the JAR name/version of each class in its produced stacktraces.

see also http://docs.oracle.com/javase/8/docs/technotes/guides/versioning/spec/versioning2.html#wp90779

You have three options:

1. Use a StringBuilder:

   StringBuilder zText = new StringBuilder ();
   void fillString(StringBuilder zText) { zText.append ("foo"); }
   

2. Create a container class and pass an instance of the container to your method:

   public class Container { public String data; }
   void fillString(Container c) { c.data += "foo"; }
   

3. Create an array:

   new String[] zText = new String[1];
   zText[0] = "";
   
   void fillString(String[] zText) { zText[0] += "foo"; }
   

From a performance point of view, the StringBuilder is usually the best option.

i faced this issue but i was able to correct this issue by renaming the controller, please have a try on it.

ctrlSub.execSummaryDocuments = function(){};

Your module and your class AthleteList have the same name. The line

import AthleteList

imports the module and creates a name AthleteList in your current scope that points to the module object. If you want to access the actual class, use

AthleteList.AthleteList

In particular, in the line

return(AthleteList(templ.pop(0), templ.pop(0), templ))

you are actually accessing the module object and not the class. Try

return(AthleteList.AthleteList(templ.pop(0), templ.pop(0), templ))

Instead of passing functions or querying it on the controller, I think what you need is relationships on models since these are related tables on your database.

If based on your structure, input_details and products are related you should put relationship definition on your models like this:

public class InputDetail(){
 protected $table = "input_details";
 ....//other code

 public function product(){
   return $this->hasOne('App\Product');
 }
}

then in your view you'll just have to say:

<p>{{ $input_details->product->name }}</p>

More simpler that way. It is also the best practice that controllers should only do business logic for the current resource. For more info on how to do this just go to the docs: https://laravel.com/docs/5.0/eloquent#relationships

I wrote a script and created a git repository, which solves this issue here: https://github.com/Cazaimi/boot-github-shell-win .

The readme contains instructions on how to set the script up, so that each time you open a new window/tab the private key is added to ssh-agent automatically, and you don't have to worry about this, if you're working with remote git repositories.

You can use Ansible stat module to register the file, and when module to apply the condition.

- name: Register file
      stat:
        path: "/tmp/test_file"
      register: file_path

- name: Create file if it doesn't exists
      file: 
        path: "/tmp/test_file"
        state: touch
      when: file_path.stat.exists == False

Without awk ?... But it's so simple with awk:

echo 'maps.google.com' | awk -F. '{print $NF}'

AWK is a way more powerful tool to have in your pocket. -F if for field separator NF is the number of fields (also stands for the index of the last)

You need to have the class inside a folder Devices.

example of textarea for disable the resize option

<textarea CLASS="foo"></textarea>

<style>
textarea.foo
{
resize:none;
}

</style>

You can loop through the table variable or you can cursor through it. This is what we usually call a RBAR - pronounced Reebar and means Row-By-Agonizing-Row.

I would suggest finding a SET-BASED answer to your question (we can help with that) and move away from rbars as much as possible.

It seems that your action needs k but ModelBinder can not find it (from form, or request or view data or ..) Change your action to this:

public ActionResult DetailsData(int? k)
    {

        EmployeeContext Ec = new EmployeeContext();
        if (k != null)
        {
           Employee emp = Ec.Employees.Single(X => X.EmpId == k.Value);

           return View(emp);
        }
        return View();
    }

You're correct, length is a data member, not a method.

From the Arrays tutorial:

The length of an array is established when the array is created. After creation, its length is fixed.

for finding a specific value of a column you can use the code below

irrespective of the preference you can use the any of the method you like

df.col_name.value_counts().Value_you_are_looking_for

take example of the titanic dataset

df.Sex.value_counts().male

this gives a count of all male on the ship Although if you want to count a numerical data then you cannot use the above method because value_counts() is used only with series type of data hence fails So for that you can use the second method example

the second method is

#this is an example method of counting on a data frame
df[(df['Survived']==1)&(df['Sex']=='male')].counts()

this is not that efficient as value_counts() but surely will help if you want to count values of a data frame hope this helps

A simple switch statement should do the trick:

function abc() {
    var elem=document.getElementById('test'),color;
    switch(elem.style.color) {
        case('red'):
            color='black';
            break;
        case('black'):
        default:
            color='red';
    }
    elem.style.color=color;
}

try this command :

df.show(df.count())

"this" is all about scope. Every function has its own scope, and since everything in JS is an object, even a function can store some values into itself using "this". OOP 101 teaches that "this" is only applicable to instances of an object. Therefore, every-time a function executes, a new "instance" of that function has a new meaning of "this".

Most people get confused when they try to use "this" inside of anonymous closure functions like:

(function(value) {
    this.value = value;
    $('.some-elements').each(function(elt){
        elt.innerHTML = this.value;        // uh oh!! possibly undefined
    });
})(2);

So here, inside each(), "this" doesn't hold the "value" that you expect it to (from

this.value = value;

(function(value) {
    var self = this;            // small change
    self.value = value;
    $('.some-elements').each(function(elt){
        elt.innerHTML = self.value;        // phew!! == 2 
    });
})(2);

Try it out; you'll begin to like this pattern of programming

Using only standard library distributed with Python:

import itertools

def nCk(n, k):
    return len(list(itertools.combinations(range(n), k)))

This is the documentation that you want: http://msdn.microsoft.com/en-us/library/aa292114(VS.71).aspx

I guess the answer is, yes, there is an equivalent that will accomplish the same thing, integrated with Windows security.

Your current solution does not work because $time is a string - it needs to be a Unix timestamp. You can do this instead:

$unix_time = strtotime('January 1 2010 '.$time); // create a unix timestamp
$startTime date( "H:i", strtotime('-30 minutes', $unix_time) );
$endTime date( "H:i", strtotime('+30 minutes', $unix_time) );

Element.matches()

element.matches(selectorString)

According to MDN Web Docs:

The Element.matches() method returns true if the element would be selected by the specified selector string; otherwise, returns false.

Therefore, you can use Element.matches() to determine if an element contains a class.

const element = document.querySelector('#example');

console.log(element.matches('.foo')); // true

<div id="example" class="foo bar"></div>

View Browser Compatibility

The answer provided by elwyn is correct. But you should also update protractor config for e2e.

In angular.json,

"serve": {
      "builder": "@angular-devkit/build-angular:dev-server",
      "options": {
        "port": 9000,
        "browserTarget": "app:build"
      }
    }

In e2e/protractor.conf.js

exports.config = {
    allScriptsTimeout: 11000,
    specs: [
        './src/**/*.e2e-spec.ts'
    ],
    capabilities: {
        'browserName': 'chrome'
    },
    directConnect: true,
    baseUrl: 'http://localhost:9000/'
}

You should look at the shelve and pickle modules. If you need to store a lot of data it may be better to use a database

Run the following query in the mysql console:

SHOW CREATE TABLE momento_distribution

Check for the line that looks something like

CONSTRAINT `momento_distribution_FK_1` FOREIGN KEY (`momento_id`) REFERENCES `momento` (`id`)

It may be different, I just put a guess as to what it could be. If you have a foreign key on both 'momento_id' & 'momento_idmember', you will get two foreign key names. The next step is to delete the foreign keys. Run the following queries:

ALTER TABLE momento_distribution DROP FOREIGN KEY momento_distribution_FK_1
ALTER TABLE momento_distribution DROP FOREIGN KEY momento_distribution_FK_2

Be sure to change the foreign key name to what you got from the CREATE TABLE query. Now you don't have any foreign keys so you can easily remove the primary key. Try the following:

ALTER TABLE  `momento_distribution` DROP PRIMARY KEY

Add the required column as follows:

ALTER TABLE  `momento_distribution` ADD  `id` INT( 11 ) NOT NULL  PRIMARY KEY AUTO_INCREMENT FIRST

This query also adds numbers so you won't need to depend on @rowid. Now you need to add the foreign key back to the earlier columns. For that, first make these indexes:

ALTER TABLE  `momento_distribution` ADD INDEX (  `momento_id` )
ALTER TABLE  `momento_distribution` ADD INDEX (  `momento_idmember` )

Now add the foreign keys. Change the Reference Table/column as you need:

ALTER TABLE  `momento_distribution` ADD FOREIGN KEY ( `momento_id`) REFERENCES  `momento` (`id`) ON DELETE RESTRICT ON UPDATE RESTRICT 
ALTER TABLE  `momento_distribution` ADD FOREIGN KEY ( `momento_idmember`) REFERENCES  `member` (`id`) ON DELETE RESTRICT ON UPDATE RESTRICT 

Hope that helps. If you get any errors, please edit the question with the structure of the reference tables & the error code(s) that you are getting.

Warning! Particularly simple answer below! :)

You actually can have a change that persists (such as a block/popup that appears and stays visible after a click) with only CSS (and without using the checkbox hack) despite what many of the (otherwise correct) answers here claim, as long as you only need persistence during the hover.

So take a look at Bojangles and TylerH's answers if those work for you, but if you want a simple and CSS only answer that will keep a block visible after being clicked on (and even can have the block disappear with a followup click), then see this solution.

I had a similar situation, I needed a popup div with onClick where I couldn't add any JS or change the markup/HTML (a truly CSS solution) and this is possible with some caveats. You can't use the :target trick that can create a nice popup unless you can change the HTML (to add an 'id') so that was out.

In my case the popup div was contained inside the other div, and I wanted the popup to appear on top of the other div, and this can be done using a combination of :active and :hover:

/* Outer div - needs to be relative so we can use absolute positioning */
.clickToShowInfo {
    position: relative;
}
/* When clicking outer div, make inner div visible */
.clickToShowInfo:active .info { display: block; }
/* And hold by staying visible on hover */
.info:hover {
    display: block;
}
/* General settings for popup */
.info {
    position: absolute;
    top: -5;
    display: none;
    z-index: 100;
    background-color: white;
    width: 200px;
    height: 200px;
}

Example (as well as one that allows clicking on the popup to make it disappear) at:

http://davesource.com/Solutions/20150324.CSS-Only-Click-to-Popup-Div/

I've also inserted a code snippet example below, but the positioning in the stackoverflow sandbox is weird so I had to put the 'click here' text after the innerDiv, which isn't normally needed.

Many devices with different screen sizes/ratios/resolutions have come out even in the last five years, including new types of iPhones and iPads. It would be very difficult to customize a website for each device.

Meanwhile, media queries for device-width, device-height, and device-aspect-ratio have been deprecated, so they may not work in future browser versions. (Source: MDN)

TLDR: Design based on browser widths, not devices. Here's a good introduction to this topic.

It is best to use native dictionaries and arrays because they have been optimized for use with swift. That being said you can use NS... classes in swift and I think this situation warrants that. Here is how you would implement it:

var path = NSBundle.mainBundle().pathForResource("Config", ofType: "plist")
var dict = NSDictionary(contentsOfFile: path)

So far (in my opinion) this is the easiest and most efficient way to access a plist, but in the future I expect that apple will add more functionality (such as using plist) into native dictionaries.

In C/C++ a string is an array of char terminated with a NULL byte ('\0');

1. Your string str has not been initialized.
2. You must concatenate strings and you are trying to concatenate a single char (without the null byte so it's not a string) to a string.

The code should look like this:

char str[1024] = "Hello World"; //this will add all characters and a NULL byte to the array
char tmp[2] = "."; //this is a string with the dot 
strcat(str, tmp);  //here you concatenate the two strings

Note that you can assign a string literal to an array only during its declaration.
For example the following code is not permitted:

char str[1024];
str = "Hello World"; //FORBIDDEN

and should be replaced with

char str[1024];
strcpy(str, "Hello World"); //here you copy "Hello World" inside the src array 

In Bash, test and [ are shell builtins.

The double bracket, which is a shell keyword, enables additional functionality. For example, you can use && and || instead of -a and -o and there's a regular expression matching operator =~.

Also, in a simple test, double square brackets seem to evaluate quite a lot quicker than single ones.

$ time for ((i=0; i<10000000; i++)); do [[ "$i" = 1000 ]]; done

real    0m24.548s
user    0m24.337s
sys 0m0.036s
$ time for ((i=0; i<10000000; i++)); do [ "$i" = 1000 ]; done

real    0m33.478s
user    0m33.478s
sys 0m0.000s

The braces, in addition to delimiting a variable name are used for parameter expansion so you can do things like:

• Truncate the contents of a variable

  $ var="abcde"; echo ${var%d*}
  abc
  

• Make substitutions similar to sed

  $ var="abcde"; echo ${var/de/12}
  abc12
  

• Use a default value

  $ default="hello"; unset var; echo ${var:-$default}
  hello
  

• and several more

Also, brace expansions create lists of strings which are typically iterated over in loops:

$ echo f{oo,ee,a}d
food feed fad

$ mv error.log{,.OLD}
(error.log is renamed to error.log.OLD because the brace expression
expands to "mv error.log error.log.OLD")

$ for num in {000..2}; do echo "$num"; done
000
001
002

$ echo {00..8..2}
00 02 04 06 08

$ echo {D..T..4}
D H L P T

Note that the leading zero and increment features weren't available before Bash 4.

Thanks to gboffi for reminding me about brace expansions.

Double parentheses are used for arithmetic operations:

((a++))

((meaning = 42))

for ((i=0; i<10; i++))

echo $((a + b + (14 * c)))

and they enable you to omit the dollar signs on integer and array variables and include spaces around operators for readability.

Single brackets are also used for array indices:

array[4]="hello"

element=${array[index]}

Curly brace are required for (most/all?) array references on the right hand side.

ephemient's comment reminded me that parentheses are also used for subshells. And that they are used to create arrays.

array=(1 2 3)
echo ${array[1]}
2

function getWeekdayDatesFrom($format, $start_date_epoch, $end_date_epoch, $range) {

    $dates_arr = array();

    if( ! $range) {
        $range = round(abs($start_date_epoch-$end_date_epoch)/86400) + 1;
    } else {
        $range = $range + 1; //end date inclusive
    }

    $current_date_epoch = $start_date_epoch;

    for($i = 1; $i <= $range; $i+1) {

        $d = date('N',  $current_date_epoch);

        if($d <= 5) { // not sat or sun
            $dates_arr[] = "'".date($format, $current_date_epoch)."'";
        }

        $next_day_epoch = strtotime('+'.$i.'day', $start_date_epoch);
        $i++;
        $current_date_epoch = $next_day_epoch;

    }

    return $dates_arr;
} 

The newer verion of PowerShell handles this and the MS Documentation has a great example of copying a file with different credentials here

$Session = New-PSSession -ComputerName "Server02" -Credential "Contoso\User01"
Copy-Item "D:\Folder002\" -Destination "C:\Folder002_Copy\" -ToSession $Session

I believe you are looking for -maxdepth 1.

You would need to add a trigger on insert, update, delete that sets a value in another table to sysdate.

When you run application, it would read the value and save it somewhere so that the next time it is run it has a reference to compare.

Would you consider that "Special Admin Stuff"?

It would be better to describe what you're actually doing so you get clearer answers.

declare @n int = 7,
    @m int = 3;

select 
    case 
        when @n = 1 then
            'SOMETEXT'
    else
        case 
            when @m = 1 then
                'SOMEOTHERTEXT'
            when @m = 2 then
                'SOMEOTHERTEXTGOESHERE'
        end
    end as col1
-- n=1 => returns SOMETEXT regardless of @m
-- n=2 and m=1 => returns SOMEOTHERTEXT
-- n=2 and m=2 => returns SOMEOTHERTEXTGOESHERE
-- n=2 and m>2 => returns null (no else defined for inner case)

You can create your mask array in one step like this

mask_data = input_mask_data < 3

This creates a boolean array which can then be used as a pixel mask. Note that we haven't changed the input array (as in your code) but have created a new array to hold the mask data - I would recommend doing it this way.

>>> input_mask_data = np.random.randint(0, 5, (3, 4))
>>> input_mask_data
array([[1, 3, 4, 0],
       [4, 1, 2, 2],
       [1, 2, 3, 0]])
>>> mask_data = input_mask_data < 3
>>> mask_data
array([[ True, False, False,  True],
       [False,  True,  True,  True],
       [ True,  True, False,  True]], dtype=bool)
>>> 

This is based on the assumption that you're getting an error about the date format, such as an invalid month value or non-numeric character when numeric expected.

Dates stored in the database do not have formats. When you query the date your client is formatting the date for display, as 4/16/2011. Normally the same date format is used for selecting and updating dates, but in this case they appear to be different - so your client is apparently doing something more complicated that SQL*Plus, for example.

When you try to update it it's using a default date format model. Because of how it's displayed you're assuming that is MM/DD/YYYY, but it seems not to be. You could find out what it is, but it's better not to rely on the default or any implicit format models at all.

Whether that is the problem or not, you should always specify the date model:

UPDATE PASOFDATE SET ASOFDATE = TO_DATE('11/21/2012', 'MM/DD/YYYY');

Since you aren't specifying a time component - all Oracle DATE columns include a time, even if it's midnight - you could also use a date literal:

UPDATE PASOFDATE SET ASOFDATE = DATE '2012-11-21';

You should maybe check that the current value doesn't include a time, though the column name suggests it doesn't.

You can also use the new HTML5 custom data- attributes.

<script type="text/javascript">
$(document).ready(function() {
    $('.my_button').click(function() {
        alert($(this).attr('data-value'));
    });
});
</script>

<button class="my_button" name="buttonName" data-value="buttonValue">Button Label</button>

If you couldn't have the items OBJ equal to null, you can do this:

$scope.isEmpty = function (obj) {
    for (var i in obj) if (obj.hasOwnProperty(i)) return false;
    return true;
};

and in the view you can do:

<div ng-show="isEmpty(items)"></div>

You can do

var ob = {};
Object.keys(ob).length

Only if your browser supports ECMAScript 5. For Example, IE 8 doesn't support this feature.

public static class HtmlHelperExtensions
{
    public static MvcHtmlString RenderPartialViewToString(
        this HtmlHelper html, 
        ControllerContext controllerContext, 
        ViewDataDictionary viewData,
        TempDataDictionary tempData,
        string viewName, 
        object model)
    {
        viewData.Model = model;
        string result = String.Empty;

        using (StringWriter sw = new StringWriter())
        {
            ViewEngineResult viewResult = ViewEngines.Engines.FindPartialView(controllerContext, viewName);
            ViewContext viewContext = new ViewContext(controllerContext, viewResult.View, viewData, tempData, sw);
            viewResult.View.Render(viewContext, sw);

            result = sw.GetStringBuilder().ToString();
        }

        return MvcHtmlString.Create(result);
    }
}

Usage in a razor view:

Html.RenderPartialViewToString(ViewContext, ViewData, TempData, "Search", Model)

If your plan is to do this as part of a query, please don't do that ^(a). Seriously, it's a performance killer. There may be situations where you don't care about performance (such as one-off migration jobs to split the fields allowing better performance in future) but, if you're doing this regularly for anything other than a mickey-mouse database, you're wasting resources.

If you ever find yourself having to process only part of a column in some way, your DB design is flawed. It may well work okay on a home address book or recipe application or any of myriad other small databases but it will not be scalable to "real" systems.

Store the components of the name in separate columns. It's almost invariably a lot faster to join columns together with a simple concatenation (when you need the full name) than it is to split them apart with a character search.

If, for some reason you cannot split the field, at least put in the extra columns and use an insert/update trigger to populate them. While not 3NF, this will guarantee that the data is still consistent and will massively speed up your queries. You could also ensure that the extra columns are lower-cased (and indexed if you're searching on them) at the same time so as to not have to fiddle around with case issues.

And, if you cannot even add the columns and triggers, be aware (and make your client aware, if it's for a client) that it is not scalable.

^(a) Of course, if your intent is to use this query to fix the schema so that the names are placed into separate columns in the table rather than the query, I'd consider that to be a valid use. But I reiterate, doing it in the query is not really a good idea.

sqlall just prints the SQL, it doesn't execute it. syncdb will create tables that aren't already created, but it won't modify existing tables.

lambda is an anonymous function, it is equivalent to:

def func(p):
   return p.totalScore     

Now max becomes:

max(players, key=func)

But as def statements are compound statements they can't be used where an expression is required, that's why sometimes lambda's are used.

Note that lambda is equivalent to what you'd put in a return statement of a def. Thus, you can't use statements inside a lambda, only expressions are allowed.

What does max do?

max(a, b, c, ...[, key=func]) -> value

With a single iterable argument, return its largest item. With two or more arguments, return the largest argument.

So, it simply returns the object that is the largest.

How does key work?

By default in Python 2 key compares items based on a set of rules based on the type of the objects (for example a string is always greater than an integer).

To modify the object before comparison, or to compare based on a particular attribute/index, you've to use the key argument.

Example 1:

A simple example, suppose you have a list of numbers in string form, but you want to compare those items by their integer value.

>>> lis = ['1', '100', '111', '2']

Here max compares the items using their original values (strings are compared lexicographically so you'd get '2' as output) :

>>> max(lis)
'2'

To compare the items by their integer value use key with a simple lambda:

>>> max(lis, key=lambda x:int(x))  # compare `int` version of each item
'111'

Example 2: Applying max to a list of tuples.

>>> lis = [(1,'a'), (3,'c'), (4,'e'), (-1,'z')]

By default max will compare the items by the first index. If the first index is the same then it'll compare the second index. As in my example, all items have a unique first index, so you'd get this as the answer:

>>> max(lis)
(4, 'e')

But, what if you wanted to compare each item by the value at index 1? Simple: use lambda:

>>> max(lis, key = lambda x: x[1])
(-1, 'z')

Comparing items in an iterable that contains objects of different type:

List with mixed items:

lis = ['1','100','111','2', 2, 2.57]

In Python 2 it is possible to compare items of two different types:

>>> max(lis)  # works in Python 2
'2'
>>> max(lis, key=lambda x: int(x))  # compare integer version of each item
'111'

But in Python 3 you can't do that any more:

>>> lis = ['1', '100', '111', '2', 2, 2.57]
>>> max(lis)
Traceback (most recent call last):
  File "<ipython-input-2-0ce0a02693e4>", line 1, in <module>
    max(lis)
TypeError: unorderable types: int() > str()

But this works, as we are comparing integer version of each object:

>>> max(lis, key=lambda x: int(x))  # or simply `max(lis, key=int)`
'111'

For getting the file size in both Linux and Mac OS X (and presumably other BSDs), there are not many options, and most of the ones suggested here will only work on one system.

Given f=/path/to/your/file,

what does work in both Linux and Mac's Bash:

size=$( perl -e 'print -s shift' "$f" )

or

size=$( wc -c "$f" | awk '{print $1}' )

The other answers work fine in Linux, but not in Mac:

• du doesn't have a -b option in Mac, and the BLOCKSIZE=1 trick doesn't work ("minimum blocksize is 512", which leads to a wrong result)

• cut -d' ' -f1 doesn't work because on Mac, the number may be right-aligned, padded with spaces in front.

So if you need something flexible, it's either perl's -s operator , or wc -c piped to awk '{print $1}' (awk will ignore the leading white space).

And of course, regarding the rest of your original question, use the -lt (or -gt) operator :

if [ $size -lt $your_wanted_size ]; then etc.

Look for define in system/core/CodeIgniter.php:

define('CI_VERSION', '3.1.8');

thinking backwards

Take the last digits only (up to 10) ignoring first "1".

function formatUSNumber(entry = '') {
  const match = entry
    .replace(/\D+/g, '').replace(/^1/, '')
    .match(/([^\d]*\d[^\d]*){1,10}$/)[0]
  const part1 = match.length > 2 ? `(${match.substring(0,3)})` : match
  const part2 = match.length > 3 ? ` ${match.substring(3, 6)}` : ''
  const part3 = match.length > 6 ? `-${match.substring(6, 10)}` : ''    
  return `${part1}${part2}${part3}`
}

example input / output as you type

formatUSNumber('+1333')
// (333)

formatUSNumber('333')
// (333)

formatUSNumber('333444')
// (333) 444

formatUSNumber('3334445555')
// (333) 444-5555

The property pDoc.parentElement or pDoc.parentNode will get you the parent element.

on shell works , sending to sdtout not , so that is one workaround, to write to stdout .

I made other approach, which is not run if sys.stdout.encoding is not define, or in others words , need export PYTHONIOENCODING=UTF-8 first to write to stdout.

import sys
if (sys.stdout.encoding is None):            
    print >> sys.stderr, "please set python env PYTHONIOENCODING=UTF-8, example: export PYTHONIOENCODING=UTF-8, when write to stdout." 
    exit(1)

so, using same example:

export PYTHONIOENCODING=UTF-8
./test.py > output.txt

will work

I can handle this way:

select to_number(to_char(sysdate,'MI')) - to_number(to_char(*YOUR_DATA_VALUE*,'MI')),max(exp_time)  from ...

Or if you want to the hour just change the MI;

select to_number(to_char(sysdate,'HH24')) - to_number(to_char(*YOUR_DATA_VALUE*,'HH24')),max(exp_time)  from ...

the others don't work for me. Good luck.

As others have noted, most likely you don't have .html set up to handle php code.

Having said that, if all you're doing is using index.html to include index.php, your question should probably be 'how do I use index.php as index document?

In which case, for Apache (httpd.conf), search for DirectoryIndex and replace the line with this (will only work if you have dir_module enabled, but that's default on most installs):

DirectoryIndex index.php

If you use other directory indexes, list them in order of preference i.e.

DirectoryIndex index.php index.phtml index.html index.htm

Looking at the code always helps too. That is, you can actually take a look at the generated partial class (that calls LoadComponent) by doing the following:

1. Go to the Solution Explorer pane in the Visual Studio solution that you are interested in.
2. There is a button in the tool bar of the Solution Explorer titled 'Show All Files'. Toggle that button.
3. Now, expand the obj folder and then the Debug or Release folder (or whatever configuration you are building) and you will see a file titled YourClass.g.cs.

The YourClass.g.cs ... is the code for generated partial class. Again, if you open that up you can see the InitializeComponent method and how it calls LoadComponent ... and much more.

[Update Sep 2016]: This answer was intended for docker compose file v1 (as shown by the sample compose file below). For v2, see the other answer by @Windsooon.

[Original answer]:

It is pretty clear in the documentation. depends_on decides the dependency and the order of container creation and links not only does these, but also

Containers for the linked service will be reachable at a hostname identical to the alias, or the service name if no alias was specified.

For example, assuming the following docker-compose.yml file:

web:
  image: example/my_web_app:latest
  links:
    - db
    - cache

db:
  image: postgres:latest

cache:
  image: redis:latest

With links, code inside web will be able to access the database using db:5432, assuming port 5432 is exposed in the db image. If depends_on were used, this wouldn't be possible, but the startup order of the containers would be correct.

This is called an initialization list. It is for passing arguments to the constructor of a parent class. Here is a good link explaining it: Initialization Lists in C++

function func(a, b)
{
  if (typeof a == 'undefined')
    a = 10;
  if (typeof b == 'undefined')
    b = 20;
  // do what you want ... for example
  alert(a + ',' + b);
}

in shorthand

function func(a, b)
{
  a = (typeof a == 'undefined')?10:a;
  b = (typeof b == 'undefined')?20:b;

  // do what you want ... for example
  alert(a + ',' + b);
}

I followed approach as shown in code below to return a dictionary. Created a class and declared dictionary as global and created a function to add value corresponding to some keys in dictionary.

**Note have used Python 2.7 so some minor modification might be required for Python 3+

class a:
    global d
    d={}
    def get_config(self,x):
        if x=='GENESYS':
            d['host'] = 'host name'
            d['port'] = '15222'
        return d

Calling get_config method using class instance in a separate python file:

from constant import a
class b:
    a().get_config('GENESYS')
    print a().get_config('GENESYS').get('host')
    print a().get_config('GENESYS').get('port')

Disadvantage of second approach is big repository with created loggers. This loggers do the same if root is defined and class loggers are not defined. Standard scenario on production system is using few loggers dedicated to group of class. Sorry for my English.

A Collection does not have an ordering, so wanting to sort it does not make sense. You can sort List instances and arrays, and the methods to do that are Collections.sort() and Arrays.sort()

ByteArrayOutputStream out = new ByteArrayOutputStream();
byte[] buffer = new byte[1024];
while (true) {
    int r = in.read(buffer);
    if (r == -1) break;
    out.write(buffer, 0, r);
}

byte[] ret = out.toByteArray();

Original from Sept. 13, 2015:
Quick and easy.

$.each(yourArray, function(index, value){
    $('.element').html( $('.element').html() + '<span>' + value +'</span>')
});

Update Sept 9, 2019: No jQuery is needed to iterate the array.

yourArray.forEach((value) => {
    $(".element").html(`${$(".element").html()}<span>${value}</span>`);
});

/* --- Or without jQuery at all --- */

yourArray.forEach((value) => {
    document.querySelector(".element").innerHTML += `<span>${value}</span>`;
});

Note that the use of unescape() is deprecated and doesn't work with the TypeScript compiler, for example.

Based on radicand's answer and the comments section below, here's an updated solution:

var string = "http\\u00253A\\u00252F\\u00252Fexample.com";
decodeURIComponent(JSON.parse('"' + string.replace(/\"/g, '\\"') + '"'));

There is no reflection in C++. True. But if the compiler can't provide you the metadata you need, you can provide it yourself.

Let's start by making a property struct:

template<typename Class, typename T>
struct PropertyImpl {
    constexpr PropertyImpl(T Class::*aMember, const char* aName) : member{aMember}, name{aName} {}

    using Type = T;

    T Class::*member;
    const char* name;
};

template<typename Class, typename T>
constexpr auto property(T Class::*member, const char* name) {
    return PropertyImpl<Class, T>{member, name};
}

Of course, you also can have a property that takes a setter and getter instead of a pointer to member, and maybe read only properties for calculated value you'd like to serialize. If you use C++17, you can extend it further to make a property that works with lambdas.

Ok, now we have the building block of our compile-time introspection system.

Now in your class Dog, add your metadata:

struct Dog {
    std::string barkType;
    std::string color;
    int weight = 0;

    bool operator==(const Dog& rhs) const {
        return std::tie(barkType, color, weight) == std::tie(rhs.barkType, rhs.color, rhs.weight);
    }

    constexpr static auto properties = std::make_tuple(
        property(&Dog::barkType, "barkType"),
        property(&Dog::color, "color"),
        property(&Dog::weight, "weight")
    );
};

We will need to iterate on that list. To iterate on a tuple, there are many ways, but my preferred one is this:

template <typename T, T... S, typename F>
constexpr void for_sequence(std::integer_sequence<T, S...>, F&& f) {
    using unpack_t = int[];
    (void)unpack_t{(static_cast<void>(f(std::integral_constant<T, S>{})), 0)..., 0};
}

If C++17 fold expressions are available in your compiler, then for_sequence can be simplified to:

template <typename T, T... S, typename F>
constexpr void for_sequence(std::integer_sequence<T, S...>, F&& f) {
    (static_cast<void>(f(std::integral_constant<T, S>{})), ...);
}

This will call a function for each constant in the integer sequence.

If this method don't work or gives trouble to your compiler, you can always use the array expansion trick.

Now that you have the desired metadata and tools, you can iterate through the properties to unserialize:

// unserialize function
template<typename T>
T fromJson(const Json::Value& data) {
    T object;

    // We first get the number of properties
    constexpr auto nbProperties = std::tuple_size<decltype(T::properties)>::value;

    // We iterate on the index sequence of size `nbProperties`
    for_sequence(std::make_index_sequence<nbProperties>{}, [&](auto i) {
        // get the property
        constexpr auto property = std::get<i>(T::properties);

        // get the type of the property
        using Type = typename decltype(property)::Type;

        // set the value to the member
        // you can also replace `asAny` by `fromJson` to recursively serialize
        object.*(property.member) = Json::asAny<Type>(data[property.name]);
    });

    return object;
}

And for serialize:

template<typename T>
Json::Value toJson(const T& object) {
    Json::Value data;

    // We first get the number of properties
    constexpr auto nbProperties = std::tuple_size<decltype(T::properties)>::value;

    // We iterate on the index sequence of size `nbProperties`
    for_sequence(std::make_index_sequence<nbProperties>{}, [&](auto i) {
        // get the property
        constexpr auto property = std::get<i>(T::properties);

        // set the value to the member
        data[property.name] = object.*(property.member);
    });

    return data;
}

If you want recursive serialization and unserialization, you can replace asAny by fromJson.

Now you can use your functions like this:

Dog dog;

dog.color = "green";
dog.barkType = "whaf";
dog.weight = 30;

Json::Value jsonDog = toJson(dog); // produces {"color":"green", "barkType":"whaf", "weight": 30}
auto dog2 = fromJson<Dog>(jsonDog);

std::cout << std::boolalpha << (dog == dog2) << std::endl; // pass the test, both dog are equal!

Done! No need for run-time reflection, just some C++14 goodness!

This code could benefit from some improvement, and could of course work with C++11 with some ajustements.

Note that one would need to write the asAny function. It's just a function that takes a Json::Value and call the right as... function, or another fromJson.

Here's a complete, working example made from the various code snippet of this answer. Feel free to use it.

As mentionned in the comments, this code won't work with msvc. Please refer to this question if you want a compatible code: Pointer to member: works in GCC but not in VS2015

transaction.commit_unless_managed()

cursor.execute("DELETE FROM myapp_style WHERE n = %s", n)

    }
}

Extending Dale Ragan's answer, his example for reuse, create an ApplicationController class which derives from Controller, and in turn have all your other controllers derive from that ApplicationController class rather than Controller.

Example:

public class MyCustomApplicationController : Controller {}

public class HomeController : MyCustomApplicationController {}

On your new ApplicationController create a property named ExecutingAction with this signature:

protected ActionDescriptor ExecutingAction { get; set; }

And then in the OnActionExecuting method (from Dale Ragan's answer), simply assign the ActionDescriptor to this property and you can access it whenever you need it in any of your controllers.

string currentActionName = this.ExecutingAction.ActionName;

var query = from s2 in (from s in someList group s by new { s.Column1, s.Column2 } into sg select sg) where s2.Count() > 1 select s2;

NSArray and NSMutableArray provide methods to filter array contents. NSArray provides filteredArrayUsingPredicate: which returns a new array containing objects in the receiver that match the specified predicate. NSMutableArray adds filterUsingPredicate: which evaluates the receiver’s content against the specified predicate and leaves only objects that match. These methods are illustrated in the following example.

NSMutableArray *array =
    [NSMutableArray arrayWithObjects:@"Bill", @"Ben", @"Chris", @"Melissa", nil];

NSPredicate *bPredicate =
    [NSPredicate predicateWithFormat:@"SELF beginswith[c] 'b'"];
NSArray *beginWithB =
    [array filteredArrayUsingPredicate:bPredicate];
// beginWithB contains { @"Bill", @"Ben" }.

NSPredicate *sPredicate =
    [NSPredicate predicateWithFormat:@"SELF contains[c] 's'"];
[array filteredArrayUsingPredicate:sPredicate];
// array now contains { @"Chris", @"Melissa" }
