I hope below code works

Firebase ref = new Firebase(FIREBASE_URL);

  ref.addValueEventListener(new ValueEventListener() {
      @Override
      public void onDataChange(DataSnapshot snapshot) {
          Log.e("Count " ,""+snapshot.getChildrenCount());
          for (DataSnapshot postSnapshot: snapshot.getChildren()) {
            <YourClass> post = postSnapshot.getValue(<YourClass>.class);
            Log.e("Get Data", post.<YourMethod>());
          }
      }
      @Override
      public void onCancelled(FirebaseError firebaseError) {
          Log.e("The read failed: " ,firebaseError.getMessage());
      }
  });

Taken from http://en.wikipedia.org/wiki/Deadlock:

In concurrent computing, a deadlock is a state in which each member of a group of actions, is waiting for some other member to release a lock

A livelock is similar to a deadlock, except that the states of the processes involved in the livelock constantly change with regard to one another, none progressing. Livelock is a special case of resource starvation; the general definition only states that a specific process is not progressing.

A real-world example of livelock occurs when two people meet in a narrow corridor, and each tries to be polite by moving aside to let the other pass, but they end up swaying from side to side without making any progress because they both repeatedly move the same way at the same time.

Livelock is a risk with some algorithms that detect and recover from deadlock. If more than one process takes action, the deadlock detection algorithm can be repeatedly triggered. This can be avoided by ensuring that only one process (chosen randomly or by priority) takes action.

Try out below drawable file. Create file named "circle" in your res/drawable folder and copy below code:

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

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

    <stroke
        android:width="1dp"
        android:color="#4a6176" />

    <padding
        android:left="10dp"
        android:right="10dp"
        android:top="10dp"
        android:bottom="10dp"
         />

    <corners android:radius="10dp" />

</shape>

Apply it in your TextView as below:

I faced this issue while i was using version control in Android Studio 2.1.3, the scenario i faces was as follows :

1- i opened the IDE and clicked on the "update / pull" icon (Ctrl+T)

2- it did not ask for the Master password and it failed, gave me this error :

Unknown SSL protocol error in connection to bitbucket.org:443

3- i tried to fetch the repository (right click > git > repository > fetch)

4- it asked me for the master password and i entered it

5- it tried to fetch but it failed again and again and again

6- i restarted Android studio

7- i tried to fetch the repository (right click > git > repository > fetch)

8- it asked me for the master password and i entered it

9- now things are OK, every thing goes fine

Conclusion :

maybe Android Studio needs the Master password first before any git actions, else it will keep failing even if it asked for Master password later on, i don't know, this is the scenario that happened to me

You can simply instantiate your fragment with a bundle:

Fragment fragment = Fragment.instantiate(this, RolesTeamsListFragment.class.getName(), bundle);

This is the correct way to change btn color.

 .btn-primary:not(:disabled):not(.disabled).active, 
    .btn-primary:not(:disabled):not(.disabled):active, 
    .show>.btn-primary.dropdown-toggle{
        color: #fff;
        background-color: #F7B432;
        border-color: #F7B432;
    }

DBL_MAX is defined in <float.h>. Its availability in <limits.h> on unix is what is marked as "(LEGACY)".

(linking to the unix standard even though you have no unix tag since that's probably where you found the "LEGACY" notation, but much of what is shown there for float.h is also in the C standard back to C89)

I think you may have to

1.Modify the source to make $.post always use JSON data type as it really is just a shortcut for a pre configured $.ajax call

Or

2.Define your own utility function that is a shortcut for the $.ajax configuration you want to use

Or

3.You could overwrite the $.post function with your own implementation via monkey patching.

The JSON datatype in your example refers to the datatype returned from the server and not the format sent to the server.

List<String> items = Arrays.asList(s.split("[,\\s]+"));

No new Calendar needs to be created, SimpleDateFormat already uses a Calendar underneath.

SimpleDateFormat sdf = new SimpleDateFormat("EEE MMM dd HH:mm:ss z yyyy", Locale.EN_US);
Date date = sdf.parse("Mon Mar 14 16:02:37 GMT 2011"));// all done
Calendar cal = sdf.getCalendar();

(I can't comment yet, that's why I created a new answer)

If you want to use numpy, you must define darr to be a numpy array, not a list:

import numpy as np
darr = np.array([1, 3.14159, 1e100, -2.71828])
print(darr.min())

darr.argmin() will give you the index corresponding to the minimum.

The reason you were getting an error is because argmin is a method understood by numpy arrays, but not by Python lists.

     would be a work around if you're only after the spacing.

You can use print -p -- in the script to do this example :

#!/bin/ksh
mysql -u username -ppassword -D dbname -ss -n -q |&
print -p -- "select count(*) from some_table;"
read -p get_row_count1
print -p -- "select count(*) from some_other_table;"
read -p get_row_count2
print -p exit ;
#
echo $get_row_count1
echo $get_row_count2
#
exit

Where is this year() function from?

You could also use the reshape2 package for this task:

require(reshape2)
df_melt <- melt(df1, id = c("date", "year", "month"))
dcast(df_melt, year + month ~ variable, sum)
#  year month         x1           x2
1  2000     1  -80.83405 -224.9540159
2  2000     2 -223.76331 -288.2418017
3  2000     3 -188.83930 -481.5601913
4  2000     4 -197.47797 -473.7137420
5  2000     5 -259.07928 -372.4563522

This webpage have an explanation and a solution.

The solution is:

To fix this problem the behavior of the kernel has to be changed, so it will no longer overcommit the memory for application requests. Finally I have included those mentioned values into the /etc/sysctl.conf file, so they get automatically applied on start-up:

vm.overcommit_memory = 2

vm.overcommit_ratio = 80

Using the Func as mentioned above works but there are also delegates that do the same task and also define intent within the naming:

public delegate double MyFunction(double x);

public double Diff(double x, MyFunction f)
{
    double h = 0.0000001;

    return (f(x + h) - f(x)) / h;
}

public double MyFunctionMethod(double x)
{
    // Can add more complicated logic here
    return x + 10;
}

public void Client()
{
    double result = Diff(1.234, x => x * 456.1234);
    double secondResult = Diff(2.345, MyFunctionMethod);
}

All the setting are stored in .metadata file in your workspace delete this and you are good to go

String target = "FOOBar";
target = target.replaceAll("(?i)foo", "");
System.out.println(target);

Output:

Bar

It's worth mentioning that replaceAll treats the first argument as a regex pattern, which can cause unexpected results. To solve this, also use Pattern.quote as suggested in the comments.

Use Guava's MoreCollectors.onlyElement() (JavaDoc).

It does what you want and throws an IllegalArgumentException if the stream consists of two or more elements, and a NoSuchElementException if the stream is empty.

Usage:

import static com.google.common.collect.MoreCollectors.onlyElement;

User match =
    users.stream().filter((user) -> user.getId() < 0).collect(onlyElement());

A more succinct idiom than the accepted answer above that's available in Rails (from 3.1.0 and above) is .in?:

my_string = "abcdefg"
if "cde".in? my_string
  puts "'cde' is in the String."
  puts "i.e. String includes 'cde'"
end

I also think it's more readable.

See the in? documentation for more information.

Note again that it's only available in Rails, and not pure Ruby.

Since Angular version 6 .angular-cli.json is deprecated. That file was replaced by angular.json file which supports workspaces.

Use a generic List (System.Collections.Generic.List).

Are you escaping? Try the mysql_real_escape_string() function and it will handle the special characters.

Sometimes something really simple, can be answered complex. I am not saying that any of the above answers are incorrect, but I would just apply, that it can be done as simple as this:

I know this question is old, but if anyone just wants to change to pin or marker color, then check out the documentation: https://developers.google.com/maps/documentation/android-sdk/marker

when you add your marker simply set the icon-property:

GoogleMap gMap;
LatLng latLng;
....
// write your code...
....
gMap.addMarker(new MarkerOptions()
    .position(latLng)
    .icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_GREEN));

There are 10 default colors to choose from. If that isn't enough (the simple solution) then I would probably go for the more complex given in the other answers, fulfilling a more complex need.

ps: I've written something similar in another answer and therefore I should refer to that answer, but the last time I did that, I was asked to post the answer since it was so short (as this one)..

The best way is to create a variable of type Worksheet, assign the worksheet and use it every time the VBA would implicitly use the ActiveSheet.

This will help you avoid bugs that will eventually show up when your program grows in size.

For example something like Range("A1:C10").Sort Key1:=Range("A2") is good when the macro works only on one sheet. But you will eventually expand your macro to work with several sheets, find out that this doesn't work, adjust it to ShTest1.Range("A1:C10").Sort Key1:=Range("A2")... and find out that it still doesn't work.

Here is the correct way:

Dim ShTest1 As Worksheet
Set ShTest1 = Sheets("Test1")
ShTest1.Range("A1:C10").Sort Key1:=ShTest1.Range("A2")

private boolean isSameDay(Date date1, Date date2) {
        Calendar calendar1 = Calendar.getInstance();
        calendar1.setTime(date1);
        Calendar calendar2 = Calendar.getInstance();
        calendar2.setTime(date2);
        boolean sameYear = calendar1.get(Calendar.YEAR) == calendar2.get(Calendar.YEAR);
        boolean sameMonth = calendar1.get(Calendar.MONTH) == calendar2.get(Calendar.MONTH);
        boolean sameDay = calendar1.get(Calendar.DAY_OF_MONTH) == calendar2.get(Calendar.DAY_OF_MONTH);
        return (sameDay && sameMonth && sameYear);
    }

• From the PHP Web site, referring to the empty() function:

Returns FALSE if var has a non-empty and non-zero value.

That’s a good thing to know. In other words, everything from NULL, to 0 to “” will return TRUE when using the empty() function.

• Here is the description of what the isset() function returns:

Returns TRUE if var exists; FALSE otherwise.

In other words, only variables that don’t exist (or, variables with strictly NULL values) will return FALSE on the isset() function. All variables that have any type of value, whether it is 0, a blank text string, etc. will return TRUE.

Static memory allocation. Memory allocated will be in stack.

int a[10];

Dynamic memory allocation. Memory allocated will be in heap.

int *a = malloc(sizeof(int) * 10);

and the latter should be freed since there is no Garbage Collector(GC) in C.

free(a);

Had this issue. My main app and extension belonged to the same app group id correctly, but there was also one more app ID not in my project that shared said app group id. I had to remove this last app ID's association with the app group.

How about the SPL version instead? It'll save you some typing:

// I changed your input example to make it harder and
// to show it works at lower depths:

$arr = array(0 => array('id'=>1,'name'=>"cat 1"),
             1 => array(array('id'=>3,'name'=>"cat 1")),
             2 => array('id'=>2,'name'=>"cat 2")
);

//here's the code:

    $arrIt = new RecursiveIteratorIterator(new RecursiveArrayIterator($arr));

 foreach ($arrIt as $sub) {
    $subArray = $arrIt->getSubIterator();
    if ($subArray['name'] === 'cat 1') {
        $outputArray[] = iterator_to_array($subArray);
    }
}

What's great is that basically the same code will iterate through a directory for you, by using a RecursiveDirectoryIterator instead of a RecursiveArrayIterator. SPL is the roxor.

The only bummer about SPL is that it's badly documented on the web. But several PHP books go into some useful detail, particularly Pro PHP; and you can probably google for more info, too.

Suppose your data looks like this:

import pandas as pd
import numpy as np

np.random.seed(2015)
df = pd.DataFrame([])
for i in range(5):
    data = dict(zip(np.random.choice(10, replace=False, size=5),
                    np.random.randint(10, size=5)))
    data = pd.DataFrame(data.items())
    data = data.transpose()
    data.columns = data.iloc[0]
    data = data.drop(data.index[[0]])
    df = df.append(data)
print('{}\n'.format(df))
# 0   0   1   2   3   4   5   6   7   8   9
# 1   6 NaN NaN   8   5 NaN NaN   7   0 NaN
# 1 NaN   9   6 NaN   2 NaN   1 NaN NaN   2
# 1 NaN   2   2   1   2 NaN   1 NaN NaN NaN
# 1   6 NaN   6 NaN   4   4   0 NaN NaN NaN
# 1 NaN   9 NaN   9 NaN   7   1   9 NaN NaN

Then it could be replaced with

np.random.seed(2015)
data = []
for i in range(5):
    data.append(dict(zip(np.random.choice(10, replace=False, size=5),
                         np.random.randint(10, size=5))))
df = pd.DataFrame(data)
print(df)

In other words, do not form a new DataFrame for each row. Instead, collect all the data in a list of dicts, and then call df = pd.DataFrame(data) once at the end, outside the loop.

Each call to df.append requires allocating space for a new DataFrame with one extra row, copying all the data from the original DataFrame into the new DataFrame, and then copying data into the new row. All that allocation and copying makes calling df.append in a loop very inefficient. The time cost of copying grows quadratically with the number of rows. Not only is the call-DataFrame-once code easier to write, it's performance will be much better -- the time cost of copying grows linearly with the number of rows.

Documentation here, and I'll use the Frankfurt region as an example.

There are 2 different URL styles:

• Virtual host style: https://BUCKET.s3.amazonaws.com/FILE
• Path style: https://s3.eu-central-1.amazonaws.com/BUCKET/FILE

But this url does not work:

• https://s3.amazonaws.com/BUCKET/FILE

The message is explicit: The bucket you are attempting to access must be addressed using the specified endpoint. Please send all future requests to this endpoint.

I may be talking about another problem because I'm not getting NoSuchKey error but I suspect the error message has been made clearer over time.

For small files and using only python built-ins, you can use the following one-liner:

with open(source, 'rb') as src, open(dest, 'wb') as dst: dst.write(src.read())

As @maxschlepzig mentioned in the comments below, this is not optimal way for applications where the file is too large or when memory is critical, thus Swati's answer should be preferred.

Using

xhrFields: { withCredentials:true }

as part of my jQuery ajax call was only part of the solution. I also needed to have the headers returned in the OPTIONS response from my resource:

Access-Control-Allow-Origin : http://www.wombling.com
Access-Control-Allow-Credentials : true

It was important that only one allowed "origin" was in the response header of the OPTIONS call and not "*". I achieved this by reading the origin from the request and populating it back into the response - probably circumventing the original reason for the restriction, but in my use case the security is not paramount.

I thought it worth explicitly mentioning the requirement for only one origin, as the W3C standard does allow for a space separated list -but Chrome doesn't! http://www.w3.org/TR/cors/#access-control-allow-origin-response-header NB the "in practice" bit.

You can call clear, and that will destroy all the objects, but that will not free the memory. Looping through the individual elements will not help either (what action would you even propose to take on the objects?) What you can do is this:

vector<tempObject>().swap(tempVector);

That will create an empty vector with no memory allocated and swap it with tempVector, effectively deallocating the memory.

C++11 also has the function shrink_to_fit, which you could call after the call to clear(), and it would theoretically shrink the capacity to fit the size (which is now 0). This is however, a non-binding request, and your implementation is free to ignore it.

A ListView is a specialized ListBox (that is, it inherits from ListBox). It allows you to specify different views rather than a straight list. You can either roll your own view, or use GridView (think explorer-like "details view"). It's basically the multi-column listbox, the cousin of windows form's listview.

If you don't need the additional capabilities of ListView, you can certainly use ListBox if you're simply showing a list of items (Even if the template is complex).

The error you quote has nothing to do with pg_hba.conf; it's failing to connect, not failing to authorize the connection.

Do what the error message says:

Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections

You haven't shown the command that produces the error. Assuming you're connecting on localhost port 5432 (the defaults for a standard PostgreSQL install), then either:

• PostgreSQL isn't running

• PostgreSQL isn't listening for TCP/IP connections (listen_addresses in postgresql.conf)

• PostgreSQL is only listening on IPv4 (0.0.0.0 or 127.0.0.1) and you're connecting on IPv6 (::1) or vice versa. This seems to be an issue on some older Mac OS X versions that have weird IPv6 socket behaviour, and on some older Windows versions.

• PostgreSQL is listening on a different port to the one you're connecting on

• (unlikely) there's an iptables rule blocking loopback connections

(If you are not connecting on localhost, it may also be a network firewall that's blocking TCP/IP connections, but I'm guessing you're using the defaults since you didn't say).

So ... check those:

• ps -f -u postgres should list postgres processes

• sudo lsof -n -u postgres |grep LISTEN or sudo netstat -ltnp | grep postgres should show the TCP/IP addresses and ports PostgreSQL is listening on

BTW, I think you must be on an old version. On my 9.3 install, the error is rather more detailed:

$ psql -h localhost -p 12345
psql: could not connect to server: Connection refused
        Is the server running on host "localhost" (::1) and accepting
        TCP/IP connections on port 12345?

If you don't globally store your map object reference, I recommend

if (L.DomUtil.get('map-canvas') !== undefined) { 
   L.DomUtil.get('map-canvas')._leaflet_id = null; 
}

where <div id="map-canvas"></div> is the object the map has been drawn into.

This way you avoid recreating the html element, which would happen, were you to remove() it.

Azure Data Studio with Postgres addin is the tool of choice to manage postgres databases for me. Check it out. https://docs.microsoft.com/en-us/sql/azure-data-studio/quickstart-postgres?view=sql-server-ver15

The 2nd parameter in the get call is a config object. You want something like this:

$http
    .get('accept.php', {
        params: {
            source: link,
            category_id: category
        }
     })
     .success(function (data,status) {
          $scope.info_show = data
     });

See the Arguments section of http://docs.angularjs.org/api/ng.$http for more detail

Create a new keypair: (go with the defaults)

ssh-keygen

Copy the public key to the server: (password for the last time)

ssh-copy-id [email protected]

From now on the server should recognize your key and not ask you for the password anymore:

ssh [email protected]

Aggregate is basically used to Group or Sum up data.

According to MSDN "Aggregate Function Applies an accumulator function over a sequence."

Example 1: Add all the numbers in a array.

int[] numbers = new int[] { 1,2,3,4,5 };
int aggregatedValue = numbers.Aggregate((total, nextValue) => total + nextValue);

*important: The initial aggregate value by default is the 1 element in the sequence of collection. i.e: the total variable initial value will be 1 by default.

variable explanation

total: it will hold the sum up value(aggregated value) returned by the func.

nextValue: it is the next value in the array sequence. This value is than added to the aggregated value i.e total.

Example 2: Add all items in an array. Also set the initial accumulator value to start adding with from 10.

int[] numbers = new int[] { 1,2,3,4,5 };
int aggregatedValue = numbers.Aggregate(10, (total, nextValue) => total + nextValue);

arguments explanation:

the first argument is the initial(starting value i.e seed value) which will be used to start addition with the next value in the array.

the second argument is a func which is a func that takes 2 int.

1.total: this will hold same as before the sum up value(aggregated value) returned by the func after the calculation.

2.nextValue: : it is the next value in the array sequence. This value is than added to the aggregated value i.e total.

Also debugging this code will give you a better understanding of how aggregate work.

You need to wrap them all in a character class. The current version means replace this sequence of characters with an empty string. When wrapped in square brackets it means replace any of these characters with an empty string.

var cleanString = dirtyString.replace(/[\|&;\$%@"<>\(\)\+,]/g, "");

Thank you, user374559 and reneD -- that code and description is very helpful.

The second approach is right to execute JavaScript code after the page has finished loading - but you don't actually execute JavaScript code there, you inserted plain HTML.
The first thing works, but loads the JavaScript immediately and clears the page (so your tag will be there - but nothing else).
(Plus: language="javascript" has been deprecated for years, use type="text/javascript" instead!)

To get that working, you have to use the DOM manipulating methods included in JavaScript. Basically you'll need something like this:

var scriptElement=document.createElement('script');
scriptElement.type = 'text/javascript';
scriptElement.src = filename;
document.head.appendChild(scriptElement);

I still have the same issue in Neon.2 My solution is to disable the JPA Configurator.

Open the Eclipse Preferences (not the project prefs!). Go to Maven --> Java EE Integration and disable the JPA Configurator. I also disabled the JAX-RS Configurator and the JSF Configurator.

From that point on the JPA Project Change Event Handler doesn't show up anymore.

Restart Eclipse if the change does not take effect immediately.

Jean-François Corbett's answer is perfect. To be exhaustive I would just like to add that with some restrictons you could also use UsedRange.Columns.Count or UsedRange.Rows.Count.
The problem is that UsedRange is not always updated when deleting rows/columns (at least until you reopen the workbook).

In a query you can just do something like:

SELECT ColumnA * ColumnB FROM table

or

SELECT ColumnA - ColumnB FROM table

You can also create computed columns in your table where you can permanently use your formula.

override func touchesBegan(touches: NSSet, withEvent event: UIEvent) {

    super.touchesBegan(touches, withEvent: event)
    let touch : UITouch = touches.anyObject() as UITouch

    if touch.view.isKindOfClass(UIPickerView)
    {

    }
}

Edit

As pointed out in @Kevin's answer, the correct way would be to use optional type cast operator as?. You can read more about it on the section Optional Chaining sub section Downcasting.

Edit 2

As pointed on the other answer by user @KPM, using the is operator is the right way to do it.

Use a for loop instead of .forEach()

var myObj = [{"a": "1","b": null},{"a": "2","b": 5}]
var result = false

for(var call of myObj) {
    console.log(call)
    
    var a = call['a'], b = call['b']
     
    if(a == null || b == null) {
        result = false
        break
    }
}

<a href="/">Same domain, just like refresh</a>

Seems to work only if your website is index.html, index.htm or index.php (any default page).

But it seems that . is the same thing and more accepted

<a href=".">Same domain, just like refresh, (more used)</a>

Both work perfect on Chrome when domain is both http:// and https://

for (NSString* key in xyz) {
    id value = xyz[key];
    // do stuff
}

This works for every class that conforms to the NSFastEnumeration protocol (available on 10.5+ and iOS), though NSDictionary is one of the few collections which lets you enumerate keys instead of values. I suggest you read about fast enumeration in the Collections Programming Topic.

Oh, I should add however that you should NEVER modify a collection while enumerating through it.

When you use the IntelliJ IDE, all the project-specific settings for the project are stored under the .idea folder.

Project settings are stored with each specific project as a set of xml files under the .idea folder. If you specify the default project settings, these settings will be automatically used for each newly created project.

Check this documentation for the IDE settings and here is their recommendation on Source Control and an example .gitignore file.

Note: If you are using git or some version control system, you might want to set this folder "ignore". Example - for git, add this directory to .gitignore. This way, the application is not IDE-specific.

Try with Contains function;

Determines whether a sequence contains a specified element.

var allowedStatus = new[]{ "A", "B", "C" };
var filteredOrders = orders.Order.Where(o => allowedStatus.Contains(o.StatusCode));

If your UIBarButtonItem is already allocated like in a storyboard. (printBtn)

    let btn = UIButton(frame: CGRect(x: 0, y: 0, width: 30, height: 30))
    btn.setImage(UIImage(named: Constants.ImageName.print)?.withRenderingMode(.alwaysTemplate), for: .normal)
    btn.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(handlePrintPress(tapGesture:))))
    printBtn.customView = btn

If you find your nested fragment not being removed or being duplicated (eg. on Activity restart, on screen rotate) try changing:

transaction.add(R.id.placeholder, newFragment);

to

transaction.replace(R.id.placeholder, newFragment);

If above doesn't help, try:

Fragment f = getChildFragmentManager().findFragmentById(R.id.placeholder);

FragmentTransaction transaction = getChildFragmentManager().beginTransaction();

if (f == null) {
    Log.d(TAG, "onCreateView: fragment doesn't exist");
    newFragment= new MyFragmentType();
    transaction.add(R.id.placeholder, newFragment);
} else {
    Log.d(TAG, "onCreateView: fragment already exists");
    transaction.replace(R.id.placeholder, f);
}
transaction.commit();

System.out.println("String"+text);

For VS2017 and 2019... with the modern core library SDK project files, the platform can be changed during the build process. Here's an example to change to the anycpu platform, just before the built-in CoreCompile task runs:

<Project Sdk="Microsoft.NET.Sdk" >

  <Target Name="SwitchToAnyCpu" BeforeTargets="CoreCompile" >
    <Message Text="Current Platform=$(Platform)" />
    <Message Text="Current PlatformTarget=$(PlatformName)" />
    <PropertyGroup>
      <Platform>anycpu</Platform>
      <PlatformTarget>anycpu</PlatformTarget>
    </PropertyGroup>
    <Message Text="New Platform=$(Platform)" />
    <Message Text="New PlatformTarget=$(PlatformTarget)" />
  </Target>

</Project>

In my case, I'm building an FPGA with BeforeTargets and AfterTargets tasks, but compiling a C# app in the main CoreCompile. (partly as I may want some sort of command-line app, and partly because I could not figure out how to omit or override CoreCompile)

To build for multiple, concurrent binaries such as x86 and x64: either a separate, manual build task would be needed or two separate project files with the respective <PlatformTarget>x86</PlatformTarget> and <PlatformTarget>x64</PlatformTarget> settings in the example, above.

Unfortunately the accepted answer did not work for me. As a temporary workaround you could also use verify=False when connecting to the secure website.

From Python Requests throwing up SSLError

requests.get('https://example.com', verify=True)

Your question implies that you're building the INSERT statement up by concatenating strings together. I suggest that this is a poor choice as it leaves you open to SQL injection attacks if the strings are derived from user input. A better choice is to use parameter markers and to bind the values to the markers. If you search for Oracle parameter markers you'll probably find some information for your specific implementation technology (e.g. C# and ADO, Java and JDBC, Ruby and RubyDBI, etc).

Read a file line by line and execute commands: 4 answers

This is because there is not only 1 answer...

1. shell command line expansion
2. xargs dedicated tool
3. while read with some remarks
4. while read -u using dedicated fd, for interactive processing (sample)

Regarding the OP request: running chmod on all targets listed in file, xargs is the indicated tool. But for some other applications, small amount of files, etc...

1. Read entire file as command line argument.

   If your file is not too big and all files are well named (without spaces or other special chars like quotes), you could use shell command line expansion. Simply:

   chmod 755 $(<file.txt)
   

   For small amount of files (lines), this command is the lighter one.

2. xargs is the right tool

   For bigger amount of files, or almost any number of lines in your input file...

   For many binutils tools, like chown, chmod, rm, cp -t ...

   xargs chmod 755 <file.txt
   

   If you have special chars and/or a lot of lines in file.txt.

   xargs -0 chmod 755 < <(tr \\n \\0 <file.txt)
   

   if your command need to be run exactly 1 time by entry:

   xargs -0 -n 1 chmod 755 < <(tr \\n \\0 <file.txt)
   

   This is not needed for this sample, as chmod accept multiple files as argument, but this match the title of question.

   For some special case, you could even define location of file argument in commands generateds by xargs:

   xargs -0 -I '{}' -n 1 myWrapper -arg1 -file='{}' wrapCmd < <(tr \\n \\0 <file.txt)
   

   Test with seq 1 5 as input

   Try this:

   xargs -n 1 -I{} echo Blah {} blabla {}.. < <(seq 1 5)
   Blah 1 blabla 1..
   Blah 2 blabla 2..
   Blah 3 blabla 3..
   Blah 4 blabla 4..
   Blah 5 blabla 5..
   

   Where commande is done once per line.

3. while read and variants.

   As OP suggest cat file.txt | while read in; do chmod 755 "$in"; done will work, but there is 2 issues:

   • cat | is an useless fork, and

   • | while ... ;done will become a subshell where environment will disapear after ;done.

   So this could be better written:

   while read in; do chmod 755 "$in"; done < file.txt
   

   But,

   • You may be warned about $IFS and read flags:

     help read
     

     read: read [-r] ... [-d delim] ... [name ...]
         ...
         Reads a single line from the standard input... The line is split
         into fields as with word splitting, and the first word is assigned
         to the first NAME, the second word to the second NAME, and so on...
         Only the characters found in $IFS are recognized as word delimiters.
         ...
         Options:
           ...
           -d delim   continue until the first character of DELIM is read, 
                      rather than newline
           ...
           -r do not allow backslashes to escape any characters
         ...
         Exit Status:
         The return code is zero, unless end-of-file is encountered...
     

     In some case, you may need to use

     while IFS= read -r in;do chmod 755 "$in";done <file.txt
     

     For avoiding problems with stranges filenames. And maybe if you encouter problems with UTF-8:

     while LANG=C IFS= read -r in ; do chmod 755 "$in";done <file.txt
     

   • While you use STDIN for reading file.txt, your script could not be interactive (you cannot use STDIN anymore).

4. while read -u, using dedicated fd.

   Syntax: while read ...;done <file.txt will redirect STDIN to file.txt. That mean, you won't be able to deal with process, until they finish.

   If you plan to create interactive tool, you have to avoid use of STDIN and use some alternative file descriptor.

   Constants file descriptors are: 0 for STDIN, 1 for STDOUT and 2 for STDERR. You could see them by:

   ls -l /dev/fd/
   

   or

   ls -l /proc/self/fd/
   

   From there, you have to choose unused number, between 0 and 63 (more, in fact, depending on sysctl superuser tool) as file descriptor:

   For this demo, I will use fd 7:

   exec 7<file.txt      # Without spaces between `7` and `<`!
   ls -l /dev/fd/
   

   Then you could use read -u 7 this way:

   while read -u 7 filename;do
       ans=;while [ -z "$ans" ];do
           read -p "Process file '$filename' (y/n)? " -sn1 foo
           [ "$foo" ]&& [ -z "${foo/[yn]}" ]&& ans=$foo || echo '??'
       done
       if [ "$ans" = "y" ] ;then
           echo Yes
           echo "Processing '$filename'."
       else
           echo No
       fi
   done 7<file.txt
   

   done
   

   To close fd/7:

   exec 7<&-            # This will close file descriptor 7.
   ls -l /dev/fd/
   

   Nota: I let striked version because this syntax could be usefull, when doing many I/O with parallels process:

   mkfifo sshfifo
   exec 7> >(ssh -t user@host sh >sshfifo)
   exec 6<sshfifo
   

On HTML5 the scrollamount and the scrolldelay attributes do not work. They are depricated attributes.

On Ubuntu/Debian, you can install it with apt-get install python-simplejson

EDIT: This answer is outdated. With things like Yarn and NPM 5's lockfiles it is now easier to ensure you're dependencies are correct on platforms like Heroku

I had a similar issue related to node_modules being modified somehow locally but the change was not reflect on Heroku, causing my app to crash. It's relatively easy fix if this is your issue:

# Remove node_modules
rm -fr node_modules

# Reinstall packages
npm i

# Commit changes
git add node_modules
git commit -m 'Fix node_modules dependencies.'
git push heroku master

Hope that helps for others with a similar issue.

Use the ALLOW_PAGE_LOCKS clause of ALTER/CREATE INDEX:

ALTER INDEX indexname ON tablename SET (ALLOW_PAGE_LOCKS = OFF);

I recently stumbled up on the same problem. Here is the synopsis of my solution:

Basic constituent code blocks needed

The following are the required basic code blocks of your client application

1. Session request section: request a session with the provider
2. Session authentication section: provide credentials to the provider
3. Client section: create the Client
4. Security Header section: add the WS-Security Header to the Client
5. Consumption section: consume available operations (or methods) as needed

What modules do you need?

Many suggested to use Python modules such as urllib2 ; however, none of the modules work-at least for this particular project.

So, here is the list of the modules you need to get. First of all, you need to download and install the latest version of suds from the following link:

pypi.python.org/pypi/suds-jurko/0.4.1.jurko.2

Additionally, you need to download and install requests and suds_requests modules from the following links respectively ( disclaimer: I am new to post in here, so I can't post more than one link for now).

pypi.python.org/pypi/requests

pypi.python.org/pypi/suds_requests/0.1

Once you successfully download and install these modules, you are good to go.

The code

Following the steps outlined earlier, the code looks like the following: Imports:

import logging
from suds.client import Client
from suds.wsse import *
from datetime import timedelta,date,datetime,tzinfo
import requests
from requests.auth import HTTPBasicAuth
import suds_requests

Session request and authentication:

username=input('Username:')
password=input('password:')
session = requests.session()
session.auth=(username, password)

Create the Client:

client = Client(WSDL_URL, faults=False, cachingpolicy=1, location=WSDL_URL, transport=suds_requests.RequestsTransport(session))

Add WS-Security Header:

...
addSecurityHeader(client,username,password)
....

def addSecurityHeader(client,username,password):
    security=Security()
    userNameToken=UsernameToken(username,password)
    timeStampToken=Timestamp(validity=600)
    security.tokens.append(userNameToken)
    security.tokens.append(timeStampToken)
    client.set_options(wsse=security)

Please note that this method creates the security header depicted in Fig.1. So, your implementation may vary depending on the correct security header format provided by the owner of the service you are consuming.

Consume the relevant method (or operation) :

result=client.service.methodName(Inputs)

Logging:

One of the best practices in such implementations as this one is logging to see how the communication is executed. In case there is some issue, it makes debugging easy. The following code does basic logging. However, you can log many aspects of the communication in addition to the ones depicted in the code.

logging.basicConfig(level=logging.INFO) 
logging.getLogger('suds.client').setLevel(logging.DEBUG) 
logging.getLogger('suds.transport').setLevel(logging.DEBUG)

Result:

Here is the result in my case. Note that the server returned HTTP 200. This is the standard success code for HTTP request-response.

(200, (collectionNodeLmp){
   timestamp = 2014-12-03 00:00:00-05:00
   nodeLmp[] = 
      (nodeLmp){
         pnodeId = 35010357
         name = "YADKIN"
         mccValue = -0.19
         mlcValue = -0.13
         price = 36.46
         type = "500 KV"
         timestamp = 2014-12-03 01:00:00-05:00
         errorCodeId = 0
      },
      (nodeLmp){
         pnodeId = 33138769
         name = "ZION 1"
         mccValue = -0.18
         mlcValue = -1.86
         price = 34.75
         type = "Aggregate"
         timestamp = 2014-12-03 01:00:00-05:00
         errorCodeId = 0
      },
 })

    }

    public static void duplicate(int[] a){
        int j = 0,count, recount, temp;
        for(int i=0; i<a.length;i++){
            count = 0;
            recount = 0;
            j=i+1;
            while(j<a.length){
                if(a[i]==a[j])
                    count++;
                j++;
            }
            if(count>0){
                temp = a[i];
                for(int x=0;x<i;x++){
                    if(a[x]==temp)
                        recount++;
                }
                if(recount==0){                 
                    totalCount++;
                    System.out.println(+a[i]+" : "+count+" times");
                }   
            }

        }
    }

}

A good place to start is the IE Standards Support Documentation.

Here is how to target IE10 in JavaScript:

if ("onpropertychange" in document && !!window.matchMedia) {
...
}

Here is how to target IE10 in CSS:

@media all and (-ms-high-contrast: none) {
...
}

In case IE11 needs to be filtered or reset via CSS, see another question: How to write a CSS hack for IE 11?

Before Java 8 (versions 7 or 6) I use the new method ArgumentMatchers.anyList:

import static org.mockito.Mockito.*;
import org.mockito.ArgumentMatchers;

verify(mock, atLeastOnce()).process(ArgumentMatchers.<Bar>anyList());

This bug is really annoying..

The only thing that did the trick for me is deleting the project from the workspace, then deleting the .project and .classpath files and then re import it back to the workspace.

Hope it will help others.

You can do something like this:

function convert(items) {
    var result = [];

    items.forEach(function (element) {
        var existingElement = result.filter(function (item) {
            return item.group === element.group;
        })[0];

        if (existingElement) {
            existingElement.color.push(element.color);
        } else {
            element.color = [element.color];
            result.push(element);
        }

    });

    return result;
}

A fast approach is to use the following according to ie that you want to focus (check the comments), inside your css files (where margin-top, set whatever css attribute you like):

margin-top: 10px\9; /*It will apply to all ie from 8 and below */
*margin-top: 10px; /*It will apply to ie 7 and below */
_margin-top: 10px; /*It will apply to ie 6 and below*/

A better approach would be to check user agent or a conditional if, in order to avoid the loading of unnecessary CSS in other browsers.

For collapse, you can try CTRL + M + O and expand using CTRL + M + P. This works in VS2008.

If you are looking for a very fast byte array equality comparer, I suggest you take a look at this STSdb Labs article: Byte array equality comparer. It features some of the fastest implementations for byte[] array equality comparing, which are presented, performance tested and summarized.

You can also focus on these implementations:

BigEndianByteArrayComparer - fast byte[] array comparer from left to right (BigEndian) BigEndianByteArrayEqualityComparer - - fast byte[] equality comparer from left to right (BigEndian) LittleEndianByteArrayComparer - fast byte[] array comparer from right to left (LittleEndian) LittleEndianByteArrayEqualityComparer - fast byte[] equality comparer from right to left (LittleEndian)

function toHHMMSS(seconds) {
    var h, m, s, result='';
    // HOURs
    h = Math.floor(seconds/3600);
    seconds -= h*3600;
    if(h){
        result = h<10 ? '0'+h+':' : h+':';
    }
    // MINUTEs
    m = Math.floor(seconds/60);
    seconds -= m*60;
    result += m<10 ? '0'+m+':' : m+':';
    // SECONDs
    s=seconds%60;
    result += s<10 ? '0'+s : s;
    return result;
}

Examples

    toHHMMSS(111); 
    "01:51"

    toHHMMSS(4444);
    "01:14:04"

    toHHMMSS(33);
    "00:33"

in Vue 2.5.1 for button works

 <button @click="firstFunction(); secondFunction();">Ok</button>

Simple way is to get the process id of mongodb and kill it. Please note DO NOT USE kill -9 pid for this as it may cause damage to the database.

so, 1. get the pid of mongodb

$ pgrep mongo

you will get pid of mongo, Now

$ kill

You may use kill -15 as well

Directly install one of the fink packages (Django 1.6 as of 2013-Nov)

fink install django-py27
fink install django-py33

Or create yourself a virtualenv:

fink install virtualenv-py27
virtualenv django-env
source django-env/bin/activate
pip install django
deactivate # when you are done

Or use fink django plus any other pip installed packages in a virtualenv

fink install django-py27
fink install virtualenv-py27
virtualenv django-env --system-site-packages
source django-env/bin/activate
# django already installed
pip install django-analytical # or anything else you might want
deactivate # back to your normally scheduled programming

Possibly one of the better examples of 'There's More Than One Way To Do It", with or without the help of CPAN.

If you have control over what you get passed as a 'date/time', I'd suggest going the DateTime route, either by using a specific Date::Time::Format subclass, or using DateTime::Format::Strptime if there isn't one supporting your wacky date format (see the datetime FAQ for more details). In general, Date::Time is the way to go if you want to do anything serious with the result: few classes on CPAN are quite as anal-retentive and obsessively accurate.

If you're expecting weird freeform stuff, throw it at Date::Parse's str2time() method, which'll get you a seconds-since-epoch value you can then have your wicked way with, without the overhead of Date::Manip.

For those looking a more modern approach, you can use the fetch API. The following example shows how to download a PDF file. It is easily done with the following code.

fetch(url, {
    body: JSON.stringify(data),
    method: 'POST',
    headers: {
        'Content-Type': 'application/json; charset=utf-8'
    },
})
.then(response => response.blob())
.then(response => {
    const blob = new Blob([response], {type: 'application/pdf'});
    const downloadUrl = URL.createObjectURL(blob);
    const a = document.createElement("a");
    a.href = downloadUrl;
    a.download = "file.pdf";
    document.body.appendChild(a);
    a.click();
})

I believe this approach to be much easier to understand than other XMLHttpRequest solutions. Also, it has a similar syntax to the jQuery approach, without the need to add any additional libraries.

Of course, I would advise checking to which browser you are developing, since this new approach won't work on IE. You can find the full browser compatibility list on the following [link][1].

Important: In this example I am sending a JSON request to a server listening on the given url. This url must be set, on my example I am assuming you know this part. Also, consider the headers needed for your request to work. Since I am sending a JSON, I must add the Content-Type header and set it to application/json; charset=utf-8, as to let the server know the type of request it will receive.

See this post where I have submitted Utils.java example to provide pure-java implementations and works without WifiManager. Some android devices may not have wifi available or are using ethernet wiring.

Utils.getMACAddress("wlan0");
Utils.getMACAddress("eth0");
Utils.getIPAddress(true); // IPv4
Utils.getIPAddress(false); // IPv6 

Basic :

CREATE TABLE table1 (
    columnA INTEGER NOT NULL,
    columnB INTEGER NOT NULL,
    PRIMARY KEY (columnA, columnB)
);

If your columns are foreign keys of other tables (common case) :

CREATE TABLE table1 (
    table2_id INTEGER NOT NULL,
    table3_id INTEGER NOT NULL,
    FOREIGN KEY (table2_id) REFERENCES table2(id),
    FOREIGN KEY (table3_id) REFERENCES table3(id),
    PRIMARY KEY (table2_id, table3_id)
);

CREATE TABLE table2 (
    id INTEGER NOT NULL,
    PRIMARY KEY id
);

CREATE TABLE table3 (
    id INTEGER NOT NULL,
    PRIMARY KEY id
);

Or simply:

PRINT SUBSTRING(@SQL_InsertQuery, 1, 8000)
PRINT SUBSTRING(@SQL_InsertQuery, 8001, 16000)

.+,(.+)

Explanation:

.+,

will search for everything before the comma, including the comma.

(.+) 

will search for everything after the comma, and depending on your regex environment,

\1

is the reference for the first parentheses captured group that you need, in this example, everything after the comma.

• Install local webserver for java e.g Tomcat,for php you can use lamp etc
• Drop the json file in the public accessible app server directory

• 

• Start the app server,and you should be able to access the file from localhost

After some years with node, I can say that there are no conventions for the directory/file structure. However most (professional) express applications use a setup like:

/
  /bin - scripts, helpers, binaries
  /lib - your application
  /config - your configuration
  /public - your public files
  /test - your tests

An example which uses this setup is nodejs-starter.

I personally changed this setup to:

/
  /etc - contains configuration
  /app - front-end javascript files
    /config - loads config
    /models - loads models
  /bin - helper scripts
  /lib - back-end express files
    /config - loads config to app.settings
    /models - loads mongoose models
    /routes - sets up app.get('..')...
  /srv - contains public files
  /usr - contains templates
  /test - contains test files

In my opinion, the latter matches better with the Unix-style directory structure (whereas the former mixes this up a bit).

I also like this pattern to separate files:

lib/index.js

var http = require('http');
var express = require('express');

var app = express();

app.server = http.createServer(app);

require('./config')(app);

require('./models')(app);

require('./routes')(app);

app.server.listen(app.settings.port);

module.exports = app;

lib/static/index.js

var express = require('express');

module.exports = function(app) {

  app.use(express.static(app.settings.static.path));

};

This allows decoupling neatly all source code without having to bother dependencies. A really good solution for fighting nasty Javascript. A real-world example is nearby which uses this setup.

Update (filenames):

Regarding filenames most common are short, lowercase filenames. If your file can only be described with two words most JavaScript projects use an underscore as the delimiter.

Update (variables):

Regarding variables, the same "rules" apply as for filenames. Prototypes or classes, however, should use camelCase.

Update (styleguides):

• https://github.com/airbnb/javascript

Unfortunately, the string.encode() method is not always reliable. Check out this thread for more information: What is the fool proof way to convert some string (utf-8 or else) to a simple ASCII string in python

You can use the utility method in Collections class public static <T extends Comparable<? super T>> void sort(List<T> list) or

public static <T> void sort(List<T> list,Comparator<? super T> c)

Refer to Comparable and Comparator interfaces for more flexibility on sorting the object.

Good news everyone some people! Newer browsers will trigger a window resize event when the zoom is changed.

There must be a user in the AllowUsers section, in the config file /etc/ssh/ssh_config, in the remote machine. You might have to restart sshd after editing the config file.

And then you can copy for example the file "test.txt" from a remote host to the local host

scp [email protected]:test.txt /local/dir

@cool_cs you can user ~ symbol ~/Users/djorge/Desktop if it's your home dir.

In UNIX, absolute paths must start with '/'.

I wanted summerize some of the answers into one post.

First, don't think of the MD5 hash as a character string but as a hex number. Therefore, each digit is a hex digit (0-15 or 0-F) and represents four bits, not eight.

Taking that further, one byte or eight bits are represented by two hex digits, e.g. b'1111 1111' = 0xFF = 255.

MD5 hashes are 128 bits in length and generally represented by 32 hex digits.

SHA-1 hashes are 160 bits in length and generally represented by 40 hex digits.

For the SHA-2 family, I think the hash length can be one of a pre-determined set. So SHA-512 can be represented by 128 hex digits.

Again, this post is just based on previous answers.

Put this in the first line of your server.js (or whatever contains your main Node.js app):

require('events').EventEmitter.prototype._maxListeners = 0;

and the error goes away :)

For a structure definition that is to be used across more than one source file, you should definitely put it in a header file. Then include that header file in any source file that needs the structure.

The extern declaration is not used for structure definitions, but is instead used for variable declarations (that is, some data value with a structure type that you have defined). If you want to use the same variable across more than one source file, declare it as extern in a header file like:

extern struct a myAValue;

Then, in one source file, define the actual variable:

struct a myAValue;

If you forget to do this or accidentally define it in two source files, the linker will let you know about this.

You can also change the value of this database parameter for your session by using the ALTER SESSION command and use it as you wanted

ALTER SESSION SET NLS_DATE_FORMAT = 'DD-MM-YYYY';
SELECT TO_DATE('05-12-2015') FROM dual;

05/12/2015

final Properties properties = new Properties();
try (final InputStream stream =
           this.getClass().getResourceAsStream("foo.properties")) {
    properties.load(stream);
    /* or properties.loadFromXML(...) */
}

It is a pointer to a pointer, so yes, in a way it's a 2D character array. In the same way that a char* could indicate an array of chars, a char** could indicate that it points to and array of char*s.

You can change the innerHTML or outerHTML of an element on the page instead.

Here's a more manual method that works both for Website projects and Web Application projects. (you can't change the project URL from within Visual Studio for Website projects.)

Web Application projects

1. In Solution Explorer, right-click the project and click Unload Project.

2. Navigate to the IIS Express ApplicationHost.config file. By default, this file is located in:

   %userprofile%\Documents\IISExpress\config

   In recent Visual Studio versions and Web Application projects, this file is in the solution folder under [Solution Dir]\.vs\config\applicationhost.config (note the .vs folder is a hidden item)

3. Open the ApplicationHost.config file in a text editor. In the <sites> section, search for your site's name. In the <bindings> section of your site, you will see an element like this:

   <binding protocol="http" bindingInformation="*:56422:localhost" />

   Change the port number (56422 in the above example) to anything you want. e.g.:

   <binding protocol="http" bindingInformation="*:44444:localhost" />

   Bonus: You can even bind to a different host name and do cool things like:

   <binding protocol="http" bindingInformation="*:80:mysite.dev" />

   and then map mysite.dev to 127.0.0.1 in your hosts file, and then open your website from "http://mysite.dev"

4. In Solution Explorer, right-click the the project and click Reload Project.

5. In Solution Explorer, right-click the the project and select Properties.

   • Select the Web tab.

   • In the Servers section, under Use Local IIS Web server, in the Project URL box enter a URL to match the hostname and port you entered in the ApplicationHost.config file from before.

   • To the right of the Project URL box, click Create Virtual Directory. If you see a success message, then you've done the steps correctly.

   • In the File menu, click Save Selected Items.

Website projects

1. In Solution Explorer, right-click the project name and then click Remove or Delete; don't worry, this removes the project from your solution, but does not delete the corresponding files on disk.

2. Follow step 2 from above for Web Application projects.

3. In Solution Explorer, right-click the solution, select Add, and then select Existing Web Site.... In the Add Existing Web Site dialog box, make sure that the Local IIS tab is selected. Under IIS Express Sites, select the site for which you have changed the port number, then click OK.

Now you can access your website from your new hostname/port.

To help others who do not have a full disk to troubleshoot this problem, first inspect your error log (for me the path is given in my /etc/mysql/my.cnf file):

tail /var/log/mysql/error.log

My problem turned out to be a new IP address allocated after some network router reconfiguration, so I needed to change the bind-address variable.

Look at the API documentation for the java.util.Calendar class and its derivatives (you may be specifically interested in the GregorianCalendar class).

Yes, gzip will let you do this. If you simply run gzip > foo.gz, it will compress STDIN to the file foo.gz. You can also pipe data into it, like some_command | gzip > foo.gz.

When we follow object oriented php in our project , we should follow some rules to use access modifiers in php. Today we are going to learn clearly what is access modifier and how can we use it.PHP access modifiers are used to set access rights with PHP classes and their members that are the functions and variables defined within the class scope. In php there are three scopes for class members.

1. PUBLIC
2. PRIVATE
3. PROTECTED

Now, let us have a look at the following image to understand access modifier access level

Now, let us have a look at the following list to know about the possible PHP keywords used as access modifiers.

public :- class or its members defined with this access modifier will be publicly accessible from anywhere, even from outside the scope of the class.

private :- class members with this keyword will be accessed within the class itself. we can’t access private data from subclass. It protects members from outside class access.

protected :- same as private, except by allowing subclasses to access protected superclass members.

Now see the table to understand access modifier Read full article php access modifire

Unfortunately (depending on your version and release of Python) some types of objects use "free lists" which are a neat local optimization but may cause memory fragmentation, specifically by making more and more memory "earmarked" for only objects of a certain type and thereby unavailable to the "general fund".

The only really reliable way to ensure that a large but temporary use of memory DOES return all resources to the system when it's done, is to have that use happen in a subprocess, which does the memory-hungry work then terminates. Under such conditions, the operating system WILL do its job, and gladly recycle all the resources the subprocess may have gobbled up. Fortunately, the multiprocessing module makes this kind of operation (which used to be rather a pain) not too bad in modern versions of Python.

In your use case, it seems that the best way for the subprocesses to accumulate some results and yet ensure those results are available to the main process is to use semi-temporary files (by semi-temporary I mean, NOT the kind of files that automatically go away when closed, just ordinary files that you explicitly delete when you're all done with them).

In case you have only one controller and you want to access every action on root you can skip controller name like this

routes.MapRoute(
        "Default", 
        "{action}/{id}", 
        new { controller = "Home", action = "Index", 
        id = UrlParameter.Optional }
);

For people that don't like horrible looking code with php tags blasted everywhere...

<?php
if (have_posts()):
  while (have_posts()) : the_post();
    the_content();
  endwhile;
else:
  echo '<p>Sorry, no posts matched your criteria.</p>';
endif;
?>

With Kotlin, it is just like this inside any function:

runOnUiThread {
   // Do work..
}

When dialing a number within the country you are in, you still need to dial the national trunk number before the rest of the number. For example, in Australia one would dial:

   0 - trunk prefix
   2 - Area code for New South Wales
6555 - STD code for a specific telephone exchange
1234 - Telephone Exchange specific extension.

For a mobile phone this becomes

   0 -      trunk prefix
   4 -      Area code for a mobile telephone
1234 5678 - Mobile telephone number

Now, when I want to dial via the international trunk, you need to drop the trunk prefix and replace it with the international dialing prefix

   + -      Short hand for the country trunk number
  61 -      Country code for Australia
   4 -      Area code for a mobile telephone
1234 5678 - Mobile telephone number

This is why you often find that the first digit of a telephone number is dropped when dialling internationally, even when using international prefixing to dial within the same country.

So as per the trunk prefix for Germany drop the 0 and add the +49 for Germany's international calling code (for example) giving:

<a href="tel:+496170961709" class="Blondie">_x000D_
    Call me, call me any, anytime_x000D_
      <b>Call me (call me) I'll arrive</b>_x000D_
        When you're ready we can share the wine!_x000D_
</a>

Using C# 7 (.NET Framework 4.6.2) you can write an IsNumeric function as a one-liner:

public bool IsNumeric(string val) => int.TryParse(val, out int result);

Note that the function above will only work for integers (Int32). But you can implement corresponding functions for other numeric data types, like long, double, etc.

You'll have to make a join:

SELECT A.SalesOrderID, B.Foo
FROM A
JOIN B bo ON bo.id = (
     SELECT TOP 1 id
     FROM B bi
     WHERE bi.SalesOrderID = a.SalesOrderID
     ORDER BY bi.whatever
     )
WHERE A.Date BETWEEN '2000-1-4' AND '2010-1-4'

, assuming that b.id is a PRIMARY KEY on B

In MS SQL 2005 and higher you may use this syntax:

SELECT SalesOrderID, Foo
FROM (
  SELECT A.SalesOrderId, B.Foo,
         ROW_NUMBER() OVER (PARTITION BY B.SalesOrderId ORDER BY B.whatever) AS rn
  FROM A
  JOIN B ON B.SalesOrderID = A.SalesOrderID
  WHERE A.Date BETWEEN '2000-1-4' AND '2010-1-4'
) i
WHERE rn

This will select exactly one record from B for each SalesOrderId.

The previous remarks about deleting or removing a connection are absolutely a possibility. But you can also get this error when you attempt to invoke a package that uses project level connections (instead of package level connections).

If you are using project level connections and still want to use dtexec, never fear there is a way. I would not recommend converting them to package level connections (assuming you created them as project level connections for a good reason).

You will need to deploy your SSIS project. Your SSIS server will need to have a catalog created (https://msdn.microsoft.com/en-us/library/gg471509.aspx). Once you have the catalog, in your SSIS project select Project->Deploy and follow the wizard. The result will be a *.ispac file generated in your SSIS solution folder/bin/Development

Now for the money command, instead of invoking your package with a simple: dtexec.exe /f "package.dtsx"

instead call it this way: dtexec.exe /project "<...>/project.ispac" /package "<...>/package.dtsx"

The ispac file has the project level connection info that is needed to execute your package and you should be set!

grep -R "somestring" | cut -d ":" -f 1

Use Console.KeyAvailable so that you only call ReadKey when you know it won't block:

Console.WriteLine("Press ESC to stop");
do {
    while (! Console.KeyAvailable) {
        // Do something
   }       
} while (Console.ReadKey(true).Key != ConsoleKey.Escape);

After some trial and tribulation, I was able to find all .msi files in a given directory and install them.

foreach($_msiFiles in 
($_msiFiles = Get-ChildItem $_Source -Recurse | Where{$_.Extension -eq ".msi"} |
 Where-Object {!($_.psiscontainter)} | Select-Object -ExpandProperty FullName)) 
{
    msiexec /i $_msiFiles /passive
}

An excellent explanation can be found here: Generate script in SQL Server Management Studio

Courtesy Ali Issa Here's what you have to do:

1. Right click the database (not the table) and select tasks --> generate scripts
2. Next --> select the requested table/tables (from select specific database objects)
3. Next --> click advanced --> types of data to script = schema and data

If you want to create a script that just generates the tables (no data) you can skip the advanced part of the instructions!

For some non-activity classes, like Worker, you're already given a Context object in the public constructor.

Worker(Context context, WorkerParameters workerParams)

You can just use that, e.g., save it to a private Context variable in the class (say, mContext), and then, for example

mContext.getSystenService(Context.ACTIVITY_SERVICE)

If you only want to read the first 999,999 (non-header) rows:

read_csv(..., nrows=999999)

If you only want to read rows 1,000,000 ... 1,999,999

read_csv(..., skiprows=1000000, nrows=999999)

nrows : int, default None Number of rows of file to read. Useful for reading pieces of large files*

skiprows : list-like or integer Row numbers to skip (0-indexed) or number of rows to skip (int) at the start of the file

and for large files, you'll probably also want to use chunksize:

chunksize : int, default None Return TextFileReader object for iteration

If by increasing the memory limit you have gotten rid of the error and your code now works, you'll need to take measures to decrease that memory usage. Here are a few things you could do to decrease it:

If you're reading files, read them line-by-line instead of reading in the complete file into memory. Look at fgets and SplFileObject::fgets. Upgrade to a new version of PHP if you're using PHP 5.3. PHP 5.4 and 5.5 use much less memory.

Avoid loading large datasets into in an array. Instead, go for processing smaller subsets of the larger dataset and, if necessary, persist your data into a database to relieve memory use.

Try the latest version or minor version of a third-party library (1.9.3 vs. your 1.8.2, for instance) and use whichever is more stable. Sometimes newer versions of libraries are written more efficiently.

If you have an uncommon or unstable PHP extension, try upgrading it. It might have a memory leak.

If you're dealing with large files and you simply can't read it line-by-line, try breaking the file into many smaller files and process those individually. Disable PHP extensions that you don't need.

In the problem area, unset variables which contain large amounts of data and aren't required later in the code.

Using asp.net, I believe you can do it this way :

myTextBox.Attributes.Add("readonly","readonly")

To extend on what womp posted, you can pass new View Data while retaining the existing View Data if you use the constructor overload of the ViewDataDictionary like so:

Html.RenderPartial(
      "ProductImageForm", 
       image, 
       new ViewDataDictionary(this.ViewData) { { "index", index } }
); 

If you have Windows 10 you can use Bash on Ubuntu on Windows to install subversion.

GCC is taking steps towards C++11, which is probably why you now need to include cstddef in order to use the NULL constant. The preferred way in C++11 is to use the new nullptr keyword, which is implemented in GCC since version 4.6. nullptr is not implicitly convertible to integral types, so it can be used to disambiguate a call to a function which has been overloaded for both pointer and integral types:

void f(int x);
void f(void * ptr);

f(0);  // Passes int 0.
f(nullptr);  // Passes void * 0.

You do not have to reference std::cout or std::endl explicitly.
They are both included in the namespace std. using namespace std instead of using scope resolution operator :: every time makes is easier and cleaner.

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

If you are going to need it for html:

import lxml.html as html
root  = html.fromstring(string)
root.xpath('//meta')

Here you go:

(new Date()).toLocaleDateString('en-US');

That's it !!

you can use it on any date object

let's say.. you have an object called "currentDate"

var currentDate = new Date(); //use your date here
currentDate.toLocaleDateString('en-US'); // "en-US" gives date in US Format - mm/dd/yy

(or)

If you want it in local format then

currentDate.toLocaleDateString(); // gives date in local Format

Plain and simple:

plt.plot(x, y, 'r-', alpha=0.7)

(I know I add nothing new, but the straightforward answer should be visible).

With a wider view of what you're actually trying to do and the context in which you're doing it, I'm sure we could give you a better answer than the literal answer to your question.

But here's a literal answer:

If you're assigning these functions to some property somewhere, you can wrap the original function and put your replacement on the property instead:

// Original code in main.js
var theProperty = init;

function init(){
     doSomething();
}

// Extending it by replacing and wrapping, in extended.js
theProperty = (function(old) {
    function extendsInit() {
        old();
        doSomething();
    }

    return extendsInit;
})(theProperty);

If your functions aren't already on an object, you'd probably want to put them there to facilitate the above. For instance:

// In main.js
var MyLibrary = {
    init: function init() {
    }
};

// In extended.js
(function() {
    var oldInit = MyLibrary.init;
    MyLibrary.init = extendedInit;
    function extendedInit() {
        oldInit.call(MyLibrary); // Use #call in case `init` uses `this`
        doSomething();
    }
})();

But there are better ways to do that. Like for instance, providing a means of registering init functions.

// In main.js
var MyLibrary = (function() {
    var initFunctions = [];
    return {
        init: function init() {
            var fns = initFunctions;
            initFunctions = undefined;
            for (var index = 0; index < fns.length; ++index) {
                try { fns[index](); } catch (e) { }
            }
        },
        addInitFunction: function addInitFunction(fn) {
            if (initFunctions) {
                // Init hasn't run yet, remember it
                initFunctions.push(fn);
            } else {
                // `init` has already run, call it almost immediately
                // but *asynchronously* (so the caller never sees the
                // call synchronously)
                setTimeout(fn, 0);
            }
        }
    };
})();

Here in 2020 (or really any time after ~2016), that can be written a bit more compactly:

// In main.js
const MyLibrary = (() => {
    let initFunctions = [];
    return {
        init() {
            const fns = initFunctions;
            initFunctions = undefined;
            for (const fn of fns) {
                try { fn(); } catch (e) { }
            }
        },
        addInitFunction(fn) {
            if (initFunctions) {
                // Init hasn't run yet, remember it
                initFunctions.push(fn);
            } else {
                // `init` has already run, call it almost immediately
                // but *asynchronously* (so the caller never sees the
                // call synchronously)
                setTimeout(fn, 0);
                // Or: `Promise.resolve().then(() => fn());`
                // (Not `.then(fn)` just to avoid passing it an argument)
            }
        }
    };
})();

If can deviate a little from the straight path of DataTable -> SQL table, it can also be done via a list of objects:

1) DataTable -> Generic list of objects

public static DataTable ConvertTo<T>(IList<T> list)
{
    DataTable table = CreateTable<T>();
    Type entityType = typeof(T);
    PropertyDescriptorCollection properties = TypeDescriptor.GetProperties(entityType);

    foreach (T item in list)
    {
        DataRow row = table.NewRow();

        foreach (PropertyDescriptor prop in properties)
        {
            row[prop.Name] = prop.GetValue(item);
        }

        table.Rows.Add(row);
    }

    return table;
}

Source and more details can be found here. Missing properties will remain to their default values (0 for ints, null for reference types etc.)

2) Push the objects into the database

One way is to use EntityFramework.BulkInsert extension. An EF datacontext is required, though.

It generates the BULK INSERT command required for fast insert (user defined table type solution is much slower than this).

Although not the straight method, it helps constructing a base of working with list of objects instead of DataTables which seems to be much more memory efficient.

For my case, I was trying to execute procedure code in MySQL, and due to some issue with server in which Server can't figure out where to end the statement I was getting Error Code 1064. So I wrapped the procedure with custom DELIMITER and it worked fine.

For example, Before it was:

DROP PROCEDURE IF EXISTS getStats;
CREATE PROCEDURE `getStats` (param_id INT, param_offset INT, param_startDate datetime, param_endDate datetime)
BEGIN
    /*Procedure Code Here*/
END;

After putting DELIMITER it was like this:

DROP PROCEDURE IF EXISTS getStats;
DELIMITER $$
CREATE PROCEDURE `getStats` (param_id INT, param_offset INT, param_startDate datetime, param_endDate datetime)
BEGIN
    /*Procedure Code Here*/
END;
$$
DELIMITER ;

While constructs are terminated not with an End While but with a Wend.

While counter < 20
    counter = counter + 1
Wend

Note that this information is readily available in the documentation; just press F1. The page you link to deals with Visual Basic .NET, not VBA. While (no pun intended) there is some degree of overlap in syntax between VBA and VB.NET, one can't just assume that the documentation for the one can be applied directly to the other.

Also in the VBA help file:

Tip The Do...Loop statement provides a more structured and flexible way to perform looping.

You were right to look at using a set, we just need to dig in a little deeper to get your method to work.

First, the example code:

test_1 = {"foo": "bar", "FOO": "BAR"}
test_2 = {"foo": "bar", "f00": "b@r"}

We can see right now that both dictionaries contain a similar key/value pair:

{"foo": "bar", ...}

Each dictionary also contains a completely different key value pair. But how do we detect the difference? Dictionaries don't support that. Instead, you'll want to use a set.

Here is how to turn each dictionary into a set we can use:

set_1 = set(test_1.items())
set_2 = set(test_2.items())

This returns a set containing a series of tuples. Each tuple represents one key/value pair from your dictionary.

Now, to find the difference between set_1 and set_2:

print set_1 - set_2
>>> {('FOO', 'BAR')}

Want a dictionary back? Easy, just:

dict(set_1 - set_2)
>>> {'FOO': 'BAR'}

Since your controller actions execute on the server, and JavaScript (usually) executes on the client (browser), this doesn't make sense. If you need some action to happen by default once the page is loaded into the browser, you can use JavaScript's document.OnLoad event handler.

What I would do is create a Boolean outside your function that starts out as FALSE and gets set to TRUE when you attach the event. This would serve as some sort of flag for you before you attach the event again. Here's an example of the idea.

// initial load
var attached = false;

// this will only execute code once
doSomething = function()
{
 if (!attached)
 {
  attached = true;
  //code
 }
} 

//attach your function with change event
window.onload = function()
{
 var txtbox = document.getElementById('textboxID');

 if (window.addEventListener)
 {
  txtbox.addEventListener('change', doSomething, false);
 }
 else if(window.attachEvent)
 {
  txtbox.attachEvent('onchange', doSomething);
 }
}

I was able to undo another user's checkout with the following command:

tf undo {file path} /workspace:{workspace};{username}

You'll need to wrap that semicolon in double-quotes if you're running the command from PowerShell. We're running TFS 2010 (and VS 2010).

Disclaimer: I got this from the FCI-H blog at http://fci-h.blogspot.com/2011/01/how-to-force-undo-checkout-tfs.html

the type just tells you what the bit pattern is supposed to represent. the bits are only what you make of them. the same sequences can be interpreted in different ways.

If file size is still too large it could help using ps2pdf to downscale the resolution of the produced pdf file:

pdf2ps input.pdf tmp.ps
ps2pdf -dPDFSETTINGS=/screen -dDownsampleColorImages=true -dColorImageResolution=200 -dColorImageDownsampleType=/Bicubic tmp.ps output.pdf

Adjust the value of the -dColorImageResolution option to achieve a result that fits your needs (the value describes the image resolution in DPIs). If your input file is in grayscale, replacing Color through Gray or using both options in the above command could also help. Further fine-tuning is possible by changing the -dPDFSETTINGS option to /default or /printer. For explanations of the all possible options consult the ps2pdf manual.

DESCRIBE <table>; 

This is acutally a shortcut for:

SHOW COLUMNS FROM <table>;

In any case, there are three possible values for the "Key" attribute:

1. PRI
2. UNI
3. MUL

The meaning of PRI and UNI are quite clear:

• PRI => primary key
• UNI => unique key

The third possibility, MUL, (which you asked about) is basically an index that is neither a primary key nor a unique key. The name comes from "multiple" because multiple occurrences of the same value are allowed. Straight from the MySQL documentation:

If Key is MUL, the column is the first column of a nonunique index in which multiple occurrences of a given value are permitted within the column.

There is also a final caveat:

If more than one of the Key values applies to a given column of a table, Key displays the one with the highest priority, in the order PRI, UNI, MUL.

As a general note, the MySQL documentation is quite good. When in doubt, check it out!

Using some ascii number tricks:

# See http://ascii.cl/
upper = {ascii:chr(ascii) for ascii in range(65,91)}
lower = {ascii:chr(ascii) for ascii in range(97,123)}
digit = {ascii:chr(ascii) for ascii in range(48,58)}


def ceasar(s, k):
    for c in s:
        o = ord(c)
        # Do not change symbols and digits
        if (o not in upper and o not in lower) or o in digit:
            yield o
        else:
            # If it's in the upper case and
            # that the rotation is within the uppercase
            if o in upper and o + k % 26 in upper:
                yield o + k % 26
            # If it's in the lower case and
            # that the rotation is within the lowercase
            elif o in lower and o + k % 26 in lower:
                yield o + k % 26
            # Otherwise move back 26 spaces after rotation.
            else: # alphabet.
                yield o + k % 26 -26

x = (''.join(map(chr, ceasar(s, k))))
print (x)

Forking creates an entirely new repository from existing repository (simply doing git clone on gitHub/bitbucket)

Forks are best used: when the intent of the ‘split’ is to create a logically independent project, which may never reunite with its parent.

Branch strategy creates a new branch over the existing/working repository

Branches are best used: when they are created as temporary places to work through a feature, with the intent to merge the branch with the origin.

More Specific :- In open source projects it is the owner of the repository who decides who can push to the repository. However, the idea of open source is that everybody can contribute to the project.

This problem is solved by forks: any time a developer wants to change something in an open source project, they don’t clone the official repository directly. Instead, they fork it to create a copy. When the work is finished, they make a pull request so that the owner of the repository can review the changes and decide whether to merge them to his project.

At its core forking is similar to feature branching, but instead of creating branches a fork of the repository is made, and instead of doing a merge request you create a pull request.

The below links provide the difference in a well-explained manner :

typeOf is a C# keyword that is used when you have the name of the class. It is calculated at compile time and thus cannot be used on an instance, which is created at runtime. GetType is a method of the object class that can be used on an instance.

Is you want a plus (+) symbol in the body you have to encode it as 2B.

For example: Try this

I encountered a similar problem, with a syntax error that I knew should not be a syntax error. In my case it turned out that a Python 2 interpreter was trying to run Python 3 code, or vice versa; I think that my shell had a PYTHONPATH with a mixture of Python 2 and Python 3.

Should not enclose true with double quote " " it should be like

$(document).ready(function() {            
   $('input').attr('required', true);   
});

Also you can use prop

jQuery(document).ready(function() {            
   $('input').prop('required', true);   
}); 

Instead of true you can try required. Such as

$('input').prop('required', 'required');

I think this is a file problem, you simple saved your file in 1-byte encoding like latin-1. Google up your editor and how to set files to utf-8.

I wonder why there are editors that don't default to utf-8.

This is a simple example of JSON parsing by taking example of google map API. This will return City name of given zip code.

Try looking at the return value of execute, which is TRUE on success, and FALSE on failure.

The selector criteria is now an attribute the DIV tag.

examples are ...

data-date-format="dd MM yyyy" 
data-date-format="dd MM yyyy - HH:ii p
data-date-format="hh:ii"

so the bootstrap example for dd mm yyyy is:-

<div class="input-group date form_date col-md-5" data-date="" 
    data-date-format="dd MM yyyy" data-link-field="dtp_input2" data-link-format="yyyy-mm-dd">
..... etc ....
</div>

my Javascript settings are as follows:-

            var picker_settings = {
                language:  'en',
                weekStart: 1,
                todayBtn:  1,
                autoclose: 1,
                todayHighlight: 1,
                startView: 2,
                minView: 2,
                forceParse: 0
            };

        $(datePickerId).datetimepicker(picker_settings);

You can see working examples of these if you download the bootstrap-datetimepicker-master file. There are sample folders each with an index.html.

Remove warnings.filterwarnings and add:

numpy.seterr(all='raise')

The second option really isn't the same as the others - if the string is "///foo" it will become "foo" instead of "//foo".

The first option needs a bit more work to understand than the third - I would view the Substring option as the most common and readable.

(Obviously each of them as an individual statement won't do anything useful - you'll need to assign the result to a variable, possibly data itself.)

I wouldn't take performance into consideration here unless it was actually becoming a problem for you - in which case the only way you'd know would be to have test cases, and then it's easy to just run those test cases for each option and compare the results. I'd expect Substring to probably be the fastest here, simply because Substring always ends up creating a string from a single chunk of the original input, whereas Remove has to at least potentially glue together a start chunk and an end chunk.

As said before, switch can be used only with integer values. So, you just need to convert your "case" values to integer. You can achieve it by using constexpr from c++11, thus some calls of constexpr functions can be calculated in compile time.

something like that...

switch (str2int(s))
{
  case str2int("Value1"):
    break;
  case str2int("Value2"):
    break;
}

where str2int is like (implementation from here):

constexpr unsigned int str2int(const char* str, int h = 0)
{
    return !str[h] ? 5381 : (str2int(str, h+1) * 33) ^ str[h];
}

Another example, the next function can be calculated in compile time:

constexpr int factorial(int n)
{
    return n <= 1 ? 1 : (n * factorial(n-1));
}  

int f5{factorial(5)};
// Compiler will run factorial(5) 
// and f5 will be initialized by this value. 
// so programm instead of wasting time for running function, 
// just will put the precalculated constant to f5 

for java8 we can simply use removeIf function like this

listValues.removeIf(value -> value.type == "Deleted");

If you need to share resources, you really should use threads.

Also consider the fact that context switches between threads are much less expensive than context switches between processes.

I see no reason to explicitly go with separate processes unless you have a good reason to do so (security, proven performance tests, etc...)

Using Process.Start:

using System.Diagnostics;

class Program
{
    static void Main()
    {
        Process.Start("example.txt");
    }
}

You can also use sendmail:

/usr/sbin/sendmail [email protected] < /file/to/send

As far as I'm aware, you've got three options to install zsh on Mac OS X:

• Pre-built binary. The only one I know of is the one that ships with OS X; this is probably what you're running now.
• Use a package system (Ports, Homebrew).
• Install from source. Last time I did this it wasn't too difficult (./configure, make, make install).

This is the answer, hope it helps someone :)

First there are two variations on how the xml can be written:

1

<row>
    <IdInvernadero>8</IdInvernadero>
    <IdProducto>3</IdProducto>
    <IdCaracteristica1>8</IdCaracteristica1>
    <IdCaracteristica2>8</IdCaracteristica2>
    <Cantidad>25</Cantidad>
    <Folio>4568457</Folio>
</row>
<row>
    <IdInvernadero>3</IdInvernadero>
    <IdProducto>3</IdProducto>
    <IdCaracteristica1>1</IdCaracteristica1>
    <IdCaracteristica2>2</IdCaracteristica2>
    <Cantidad>72</Cantidad>
    <Folio>4568457</Folio>
</row>

Answer:

SELECT  
       Tbl.Col.value('IdInvernadero[1]', 'smallint'),  
       Tbl.Col.value('IdProducto[1]', 'smallint'),  
       Tbl.Col.value('IdCaracteristica1[1]', 'smallint'),
       Tbl.Col.value('IdCaracteristica2[1]', 'smallint'),
       Tbl.Col.value('Cantidad[1]', 'int'),
       Tbl.Col.value('Folio[1]', 'varchar(7)')
FROM   @xml.nodes('//row') Tbl(Col)  

2.

<row IdInvernadero="8" IdProducto="3" IdCaracteristica1="8" IdCaracteristica2="8" Cantidad ="25" Folio="4568457" />                         
<row IdInvernadero="3" IdProducto="3" IdCaracteristica1="1" IdCaracteristica2="2" Cantidad ="72" Folio="4568457" />

Answer:

SELECT  
       Tbl.Col.value('@IdInvernadero', 'smallint'),  
       Tbl.Col.value('@IdProducto', 'smallint'),  
       Tbl.Col.value('@IdCaracteristica1', 'smallint'),
       Tbl.Col.value('@IdCaracteristica2', 'smallint'),
       Tbl.Col.value('@Cantidad', 'int'),
       Tbl.Col.value('@Folio', 'varchar(7)')

FROM   @xml.nodes('//row') Tbl(Col)

You can use the following code for your requirement

map.forEach((k,v)->System.out.println("Item : " + k + " Count : " + v));

You may have to enable the HTTPS part:

curl_setopt($c, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($c, CURLOPT_SSL_VERIFYHOST,  2);

And if you need to verify (authenticate yourself) you may need this too:

curl_setopt($c, CURLOPT_USERPWD, 'username:password');

The vshost.exe feature was introduced with Visual Studio 2005 (to answer your comment).

The purpose of it is mostly to make debugging launch quicker - basically there's already a process with the framework running, just ready to load your application as soon as you want it to.

See this MSDN article and this blog post for more information.

First, you'll need to add session_start() at the top of any page that you wish to use SESSION variables on.

Also, you should check to make sure the variable is set first before using it:

if(isset($_SESSION['SESS_fname'])){
    echo $_SESSION['SESS_fname'];
}

Or, simply:

echo (isset($_SESSION['SESS_fname']) ? $_SESSION['SESS_fname'] : "Visitor");

My approach, i think coming more from an development than an operations point of view, is:

• Error means that the execution of some task could not be completed; an email couldn't be sent, a page couldn't be rendered, some data couldn't be stored to a database, something like that. Something has definitively gone wrong.
• Warning means that something unexpected happened, but that execution can continue, perhaps in a degraded mode; a configuration file was missing but defaults were used, a price was calculated as negative, so it was clamped to zero, etc. Something is not right, but it hasn't gone properly wrong yet - warnings are often a sign that there will be an error very soon.
• Info means that something normal but significant happened; the system started, the system stopped, the daily inventory update job ran, etc. There shouldn't be a continual torrent of these, otherwise there's just too much to read.
• Debug means that something normal and insignificant happened; a new user came to the site, a page was rendered, an order was taken, a price was updated. This is the stuff excluded from info because there would be too much of it.
• Trace is something i have never actually used.

I really don't understand some of the hoops the other answers are jumping through.

var myString = "    this    is my String ";
var newstring = myString.Trim(); // results in "this is my String"
var noSpaceString = myString.Replace(" ", ""); // results in "thisismyString";

It's not rocket science.

Try this:

var itemsInCart = from o in db.OrderLineItems
                  where o.OrderId == currentOrder.OrderId
                  select o.WishListItem.Price;

return Convert.ToDecimal(itemsInCart.Sum());

I think it's more simple!

I had the same problem adn did not want this to be set globally, so I used the same TrustManager and SSLContext code as above, I just changed the Client to be created with special properties

 ClientConfig config = new DefaultClientConfig();
 config.getProperties().put(HTTPSProperties.PROPERTY_HTTPS_PROPERTIES, new HTTPSProperties(
     new HostnameVerifier() {
         @Override
         public boolean verify( String s, SSLSession sslSession ) {
             // whatever your matching policy states
         }
     }
 ));
 Client client = Client.create(config);

I solved the problem by removing the clickable views from the list.

I was going to add this just to be silly, but also because it shows newcomers the potential usefulness of aliasing functions and/or imports.

Having written it, I think this code is more readable (i.e. lower time to grasp intention) than the other answers to date, and readability is (usually) king.

from os.path import dirname as up

two_up = up(up(__file__))

Note: you only want to do this kind of thing if your module is very small, or contextually cohesive.

If you're feeling creative you could do something like this. Loop backwards through the dictionary to make your changes.

Dictionary<string, int> collection = new Dictionary<string, int>();
collection.Add("value1", 9);
collection.Add("value2", 7);
collection.Add("value3", 5);
collection.Add("value4", 3);
collection.Add("value5", 1);

for (int i = collection.Keys.Count; i-- > 0; ) {
    if (collection.Values.ElementAt(i) < 5) {
        collection.Remove(collection.Keys.ElementAt(i)); ;
    }

}

Certainly not identical, but you might be interested anyways...

Assuming the following method to test:

public boolean doSomething(SomeClass arg);

Mockito documentation says that you should not use captor in this way:

when(someObject.doSomething(argumentCaptor.capture())).thenReturn(true);
assertThat(argumentCaptor.getValue(), equalTo(expected));

Because you can just use matcher during stubbing:

when(someObject.doSomething(eq(expected))).thenReturn(true);

But verification is a different story. If your test needs to ensure that this method was called with a specific argument, use ArgumentCaptor and this is the case for which it is designed:

ArgumentCaptor<SomeClass> argumentCaptor = ArgumentCaptor.forClass(SomeClass.class);
verify(someObject).doSomething(argumentCaptor.capture());
assertThat(argumentCaptor.getValue(), equalTo(expected));

Go to a Packages/User, create (or edit) a .sublime-settings file named after the Syntax where you want to add the extensions, Ini.sublime-settings in your case, then write there something like this:

{
    "extensions":["cfg"]
}

And then restart Sublime Text

Read line by line, not the whole file:

for line in open(file_name, 'rb'):
    # process line here

Even better use with for automatically closing the file:

with open(file_name, 'rb') as f:
    for line in f:
        # process line here

The above will read the file object using an iterator, one line at a time.

RewriteEngine on
RewriteCond %{HTTP_HOST} ^(www\.)?olddomain\.com$ [NC]
RewriteRule ^(.*)$ "http://www.thenewdomain.com/" [R=301,L]

Since the fields are empty they are not valid, so the ng-invalid and ng-invalid-required classes are added properly.

You can use the class ng-pristine to check out whether the fields have already been used or not.

This takes advantage of ls()'s pattern option, in the case you have a lot of objects with the same pattern that you don't want to keep:

> foo1 <- "junk"; foo2 <- "rubbish"; foo3 <- "trash"; x <- "gold"  
> ls()
[1] "foo1" "foo2" "foo3" "x"   
> # Let's check first what we want to remove
> ls(pattern = "foo")
[1] "foo1" "foo2" "foo3"
> rm(list = ls(pattern = "foo"))
> ls()
[1] "x"

I was using the Windows SDK for core Win32 programming and had .NET 4.5 installed for "unknown" reasons. I have uninstalled that and installed 4.0 like previous answers and yeah, it worked for me too.

Just am flabbergasted that I had to use the useless .NET framework for building Win32 apps using the SDK.

The best working Solution of adding Custom header view in UITableView for section in swift 4 is --

1 first Use method ViewForHeaderInSection as below -

func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
        let headerView = UIView.init(frame: CGRect.init(x: 0, y: 0, width: tableView.frame.width, height: 50))

        let label = UILabel()
        label.frame = CGRect.init(x: 5, y: 5, width: headerView.frame.width-10, height: headerView.frame.height-10)
        label.text = "Notification Times"
        label.font = UIFont().futuraPTMediumFont(16) // my custom font
        label.textColor = UIColor.charcolBlackColour() // my custom colour

        headerView.addSubview(label)

        return headerView
    }

2 Also Don't forget to set Height of the header using heightForHeaderInSection UITableView method -

func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
        return 50
    }

and you're all set

My pseudocode example will be as follows:

JSONArray jsonArray = "[{id:\"1\", name:\"sql\"},{id:\"2\",name:\"android\"},{id:\"3\",name:\"mvc\"}]";
JSON newJson = new JSON();

for (each json in jsonArray) {
    String id = json.get("id");
    String name = json.get("name");

    newJson.put(id, name);
}

return newJson;

Basically, the problem lies in block12. for the block1/2 to take up the total height of the block12, it must have a defined height. This stack overflow post explains that in really good detail.

So setting a defined height for block12 will allow you to set a proper height. I have created an example on JSfiddle that will show you the the blocks can be floated next to one another if the block12 div is set to a standard height through out the page.

Here is an example including a header and block3 div with some content in for examples.

#header{
   position:absolute;
   top:0;
   left:0;
   width:100%;
   height:20%;
    }

    #block12{
    position:absolute;
    top:20%;
    width:100%;
    left:0;
    height:40%;
    }
    #block1,#block2{
    float:left;
    overflow-y: scroll;
    text-align:center;
    color:red;
    width:50%;
    height:100%;

    }
 #clear{clear:both;}
 #block3{
    position:absolute;
    bottom:0;
    color:blue;
    height:40%;

    }

I think you can just cast to ObjectNode and use put method. Like this

ObjectNode o = (ObjectNode) jsonNode; o.put("value", "NO");

class list_benefits(object):
    def __init__(self):
        self.s1 = "More organized code"
        self.s2 = "More readable code"
        self.s3 = "Easier code reuse"

def build_sentence():
        obj=list_benefits()
        print obj.s1 + " is a benefit of functions!"
        print obj.s2 + " is a benefit of functions!"
        print obj.s3 + " is a benefit of functions!"

print build_sentence()

I know it is late answer, maybe some other folk can benefit If you still want to call by "attributes", you could use class with default constructor, and create an instance of the class as mentioned in other answers

Write bytes and Create the file if not exists:

f = open('./put/your/path/here.png', 'wb')
f.write(data)
f.close()

wb means open the file in write binary mode.

Expanding on this method, applied to finding the mode of the data where you may need the index of the actual array to see how far away the value is from the center of the distribution.

(_, idx, counts) = np.unique(a, return_index=True, return_counts=True)
index = idx[np.argmax(counts)]
mode = a[index]

Remember to discard the mode when len(np.argmax(counts)) > 1

A succinct one-liner:

var max = anArray.Select((n, i) => (Number: n, Index: i)).Max();

Test case:

var anArray = new int[] { 1, 5, 7, 4, 2 };
var max = anArray.Select((n, i) => (Number: n, Index: i)).Max();
Console.WriteLine($"Maximum number = {max.Number}, on index {max.Index}.");
// Maximum number = 7, on index 2.

Features:

• Uses Linq (not as optimized as vanilla, but the trade-off is less code).
• Does not need to sort.
• Computational complexity: O(n).
• Space complexity: O(n).

Remarks:

• Make sure the number (and not the index) is the first element in the tuple because tuple sorting is done by comparing tuple items from left to right.

I got this after saving the JSON file using Notepad2, so I had to open it with Notepad++ and then say "Convert to UTF-8". Then it worked.
