There are several tools all built around Xperf. It's rather complex but very powerful -- see the quick start guide. There are other useful resources on the Windows Performance Analysis page

Check that your labels aren't set to automatically resize. In IB, it's called "Autoshrink" and is right beside the font setting. Programmatically, it's called adjustsFontSizeToFitWidth.

*

master = Tk()
entryb1 = StringVar

Label(master, text="Input: ").grid(row=0, sticky=W)

Entry(master, textvariable=entryb1).grid(row=1, column=1)

b1 = Button(master, text="continue", command=print_content)
b1.grid(row=2, column=1)

def print_content():
    global entryb1
    content = entryb1.get()
    print(content)

master.mainloop()

What you did wrong was not put it inside a Define function then you hadn't used the .get function with the textvariable you had set.

If you guys are facing "Permission Denial: starting Intent..." error or if the app is getting crash without any reason during launching the app - Then use this single line code in Manifest

android:exported="true"

Please be careful with finish(); , if you missed out it the app getting frozen. if its mentioned the app would be a smooth launcher.

finish();

The other solution only works for two activities that are in the same application. In my case, application B doesn't know class com.example.MyExampleActivity.class in the code, so compile will fail.

I searched on the web and found something like this below, and it works well.

Intent intent = new Intent();
intent.setComponent(new ComponentName("com.example", "com.example.MyExampleActivity"));
startActivity(intent);

You can also use the setClassName method:

Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setClassName("com.hotfoot.rapid.adani.wheeler.android", "com.hotfoot.rapid.adani.wheeler.android.view.activities.MainActivity");
startActivity(intent);
finish();

You can also pass the values from one app to another app :

Intent launchIntent = getApplicationContext().getPackageManager().getLaunchIntentForPackage("com.hotfoot.rapid.adani.wheeler.android.LoginActivity");
if (launchIntent != null) {
    launchIntent.putExtra("AppID", "MY-CHILD-APP1");
    launchIntent.putExtra("UserID", "MY-APP");
    launchIntent.putExtra("Password", "MY-PASSWORD");
    startActivity(launchIntent);
    finish();
} else {
    Toast.makeText(getApplicationContext(), " launch Intent not available", Toast.LENGTH_SHORT).show();
}

This should do what you want.

public function up()
{
    DB::table('user')->insert(array('username'=>'dude', 'password'=>'z19pers!'));
}

In order for a bot to send a message, you need <client>.send() , the client is where the bot will send a message to(A channel, everywhere in the server, or a PM). Since you want the bot to PM a certain user, you can use message.author as your client. (you can replace author as mentioned user in a message or something, etc)

Hence, the answer is: message.author.send("Your message here.")

I recommend looking up the Discord.js documentation about a certain object's properties whenever you get stuck, you might find a particular function that may serve as your solution.

A better way in long run is to integrate Gradle in your project environment. Its a build tool for Java, and now being used a lot in the android development space.

You will need to make a .gradle file and list your library dependencies. Then, all you would need to do is import the project in IntelliJ using Gradle.

import numpy as np    
hist, bin_edges = np.histogram([1, 1, 2, 2, 2, 2, 3], bins = range(5))

Below, hist indicates that there are 0 items in bin #0, 2 in bin #1, 4 in bin #3, 1 in bin #4.

print(hist)
# array([0, 2, 4, 1])   

bin_edges indicates that bin #0 is the interval [0,1), bin #1 is [1,2), ..., bin #3 is [3,4).

print (bin_edges)
# array([0, 1, 2, 3, 4]))  

Play with the above code, change the input to np.histogram and see how it works.

But a picture is worth a thousand words:

import matplotlib.pyplot as plt
plt.bar(bin_edges[:-1], hist, width = 1)
plt.xlim(min(bin_edges), max(bin_edges))
plt.show()   

That's because you're using a non-blocking socket and the output buffer is full.

From the send() man page

   When the message does not fit into  the  send  buffer  of  the  socket,
   send() normally blocks, unless the socket has been placed in non-block-
   ing I/O mode.  In non-blocking mode it  would  return  EAGAIN  in  this
   case.  

EAGAIN is the error code tied to "Resource temporarily unavailable"

Consider using select() to get a better control of this behaviours

I have tried this with and without the WRITE_INTERNAL_STORAGE permission.

There is no WRITE_INTERNAL_STORAGE permission in Android.

How do I create this file for writing?

You don't, except perhaps on a rooted device, if your app is running with superuser privileges. You are trying to write to the root of internal storage, which apps do not have access to.

Please use the version of the FileOutputStream constructor that takes a File object. Create that File object based off of some location that you can write to, such as:

• getFilesDir() (called on your Activity or other Context)
• getExternalFilesDir() (called on your Activity or other Context)

The latter will require WRITE_EXTERNAL_STORAGE as a permission.

Is there an easier way than writing it to a file then reading from it again?

You can temporarily put it in a static data member.

because many people don't have SD card slots

"SD card slots" are irrelevant, by and large. 99% of Android device users will have external storage -- the exception will be 4+ year old devices where the user removed their SD card. Devices manufactured since mid-2010 have external storage as part of on-board flash, not as removable media.

An object outside a function is passed into a function by giving a reference to the outside object.

When you use that reference to manipulate its object, the object outside is thus affected. However, if inside the function you decided to point the reference to something else, you did not affect the object outside at all, because all you did was re-direct the reference to something else.

You should be able to type:

var input = document.getElementById("searchTxt");_x000D_
_x000D_
function searchURL() {_x000D_
     window.location = "http://www.myurl.com/search/" + input.value;_x000D_
}

<input name="searchTxt" type="text" maxlength="512" id="searchTxt" class="searchField"/>

I'm sure there are better ways to do this, but this one seems to work across all browsers, and it requires minimal understanding of JavaScript to make, improve, and edit.

4 GB minus what is in use by the system if you link with /LARGEADDRESSAWARE.

Of course, you should be even more careful with pointer arithmetic if you set that flag.

Use hashlib.md5 in Python 3.

import hashlib

source = '000005fab4534d05api_key9a0554259914a86fb9e7eb014e4e5d52permswrite'.encode()
md5 = hashlib.md5(source).hexdigest() # returns a str
print(md5) # a02506b31c1cd46c2e0b6380fb94eb3d

If you need byte type output, use digest() instead of hexdigest().

If the service starts and stops like that, it means your code is throwing an unhandled exception. This is pretty difficult to debug, but there are a few options.

1. Consult the Windows Event Viewer. Normally you can get to this by going to the computer/server manager, then clicking Event Viewer -> Windows Logs -> Application. You can see what threw the exception here, which may help, but you don't get the stack trace.
2. Extract your program logic into a library class project. Now create two different versions of the program: a console app (for debugging), and the windows service. (This is a bit of initial effort, but saves a lot of angst in the long run.)
3. Add more try/catch blocks and logging to the app to get a better picture of what's going on.

You could write a function template back that delegates to the member function for ordinary containers and a normal function that implements the missing functionality for strings:

template <typename C>
typename C::reference back(C& container)
{
    return container.back();
}

template <typename C>
typename C::const_reference back(const C& container)
{
    return container.back();
}

char& back(std::string& str)
{
    return *(str.end() - 1);
}

char back(const std::string& str)
{
    return *(str.end() - 1);
}

Then you can just say back(foo) without worrying whether foo is a string or a vector.

Few years later, want to suggest just for this: https://github.com/casey/just

action v1 v2=default:
    @echo 'take action on {{v1}} and {{v2}}...'

try:
   a = b[n]
except IndexError:
   a = default

Edit: I removed the check for TypeError - probably better to let the caller handle this.

You are conflating Optional with having a default. An Optional accepts either a value or nil. Having a default permits the argument to be omitted in calling the function. An argument can have a default value with or without being of Optional type.

func someFunc(param1: String?,
          param2: String = "default value",
          param3: String? = "also has default value") {
    print("param1 = \(param1)")

    print("param2 = \(param2)")

    print("param3 = \(param3)")
}

Example calls with output:

someFunc(param1: nil, param2: "specific value", param3: "also specific value")

param1 = nil
param2 = specific value
param3 = Optional("also specific value")

someFunc(param1: "has a value")

param1 = Optional("has a value")
param2 = default value
param3 = Optional("also has default value")

someFunc(param1: nil, param3: nil)

param1 = nil
param2 = default value
param3 = nil

To summarize:

• Type with ? (e.g. String?) is an Optional may be nil or may contain an instance of Type
• Argument with default value may be omitted from a call to function and the default value will be used
• If both Optional and has default, then it may be omitted from function call OR may be included and can be provided with a nil value (e.g. param1: nil)

        chkRemember.Checked = true;
    }

Try this:

SELECT min(salary) 
FROM employee 
WHERE salary IN (SELECT top 2 salary FROM employee ORDER BY salary DESC)

I don't often develop in asp.net, however when it comes to loggers I think a lot of best practices are universal. Here are some of my random thoughts on logging that I have learned over the years:

Frameworks

• Use a logger abstraction framework - like slf4j (or roll your own), so that you decouple the logger implementation from your API. I have seen a number of logger frameworks come and go and you are better off being able to adopt a new one without much hassle.
• Try to find a framework that supports a variety of output formats.
• Try to find a framework that supports plugins / custom filters.
• Use a framework that can be configured by external files, so that your customers / consumers can tweak the log output easily so that it can be read by commerical log management applications with ease.
• Be sure not to go overboard on custom logging levels, otherwise you may not be able to move to different logging frameworks.

Logger Output

• Try to avoid XML/RSS style logs for logging that could encounter catastrophic failures. This is important because if the power switch is shut off without your logger writing the closing </xxx> tag, your log is broken.
• Log threads. Otherwise, it can be very difficult to track the flow of your program.
• If you have to internationalize your logs, you may want to have a developer only log in English (or your language of choice).
• Sometimes having the option to insert logging statements into SQL queries can be a lifesaver in debugging situations. Such as:

    -- Invoking Class: com.foocorp.foopackage.FooClass:9021
    SELECT * FROM foo;

• You want class-level logging. You normally don't want static instances of loggers as well - it is not worth the micro-optimization.
• Marking and categorizing logged exceptions is sometimes useful because not all exceptions are created equal. So knowing a subset of important exceptions a head of time is helpful, if you have a log monitor that needs to send notifications upon critical states.
• Duplication filters will save your eyesight and hard disk. Do you really want to see the same logging statement repeated 10^10000000 times? Wouldn't it be better just to get a message like: This is my logging statement - Repeated 100 times

Also see this question of mine.

string saveStaff = "INSERT into student (stud_id,stud_name) " + " VALUES ('" + SI+ "', '" + SN + "');";
cmd = new SqlCommand(saveStaff,con);
cmd.ExecuteNonQuery();

@John, Earlz and Nathan. The way I learned it at uni is: functions return values, methods don't. In some languages the syntax is/was actually different. Example (no specific language):

Method SetY(int y) ...
Function CalculateY(int x) As Integer ...

Most languages now use the same syntax for both versions, using void as a return type to say there actually isn't a return type. I assume it's because the syntax is more consistent and easier to change from method to function, and vice versa.

You can also done this by using group by clause

   SELECT purchases.address_id, purchases.* FROM "purchases"
    WHERE "purchases"."product_id" = 1 GROUP BY address_id,
purchases.purchased_at ORDER purchases.purchased_at DESC

In oracle an empty varchar2 and null are treated the same, and your observations show that.

when you write:

select * from table where a = '';

its the same as writing

select * from table where a = null;

and not a is null

which will never equate to true, so never return a row. same on the insert, a NOT NULL means you cant insert a null or an empty string (which is treated as a null)

If you don't want to use jquery, use this:

<script>
 // without jquery
document.addEventListener("DOMContentLoaded", function() {
 setTimeout(function() {
  // run your open popup function after 5 sec = 5000
  PopUp();
 }, 5000)
});
</script>

OR With jquery

<script>
  $(document).ready(function(){
   setTimeout(function(){
   // open popup after 5 seconds
   PopUp();
  },5000);  
 });
</script>

Use the basename method of the path module:

path.basename('/foo/bar/baz/asdf/quux.html')
// returns
'quux.html'

Here is the documentation the above example is taken from.

If multiple processes are writing to the file, you must use append mode or the data will be scrambled. Append mode will make the operating system put every write, at the end of the file irrespective of where the writer thinks his position in the file is. This is a common issue for multi-process services like nginx or apache where multiple instances of the same process, are writing to the same log file. Consider what happens if you try to seek, then write:

Example does not work well with multiple processes: 

f = open("logfile", "w"); f.seek(0, os.SEEK_END); f.write("data to write");

writer1: seek to end of file.           position 1000 (for example)
writer2: seek to end of file.           position 1000
writer2: write data at position 1000    end of file is now 1000 + length of data.
writer1: write data at position 1000    writer1's data overwrites writer2's data.

By using append mode, the operating system will place any write at the end of the file.

f = open("logfile", "a"); f.seek(0, os.SEEK_END); f.write("data to write");

Append most does not mean, "open file, go to end of the file once after opening it". It means, "open file, every write I do will be at the end of the file".

WARNING: For this to work you must write all your record in one shot, in one write call. If you split the data between multiple writes, other writers can and will get their writes in between yours and mangle your data.

If I understand your question correctly, I've made a fiddle that has this working correctly. This issue is with how you're assigning the event handlers and as others have said you have over riding event handlers. The current jQuery best practice is to use on() to register event handlers. Here's a link to the jQuery docs about on: link

Your original solution was pretty close but the way you added the event handlers is a bit confusing. It's considered best practice to not add events to HTML elements. I recommend reading up on Unobstrusive JavaScript.

Here's the JavaScript code. I added a counter variable so you can see that it is working correctly.

$('#answer').on('click', function() {
  feedback('hey there');
});

var counter = 0;

function feedback(message) {

  $('#feedback').remove();

  $('.answers').append('<div id="feedback">' + message + ' ' + counter + '</div>');

  counter++;    
}

The code is correct so I'm guessing that you are using an older JDK. The javadoc for that method says it has been there since 1.6. At the command line type:

java -version

I'm guessing that you are not running 1.6

_.map returns an Array, not an Object.

If you want an object you're better off using a different function, like each; if you really want to use map you could do something like this:

Object.keys(object).map(function(value, index) {
   object[value] *= 3;
})

but that is confusing, when seeing map one would expect to have an array as result and then make something with it.

From cppreference, one of the std::unique_ptr constructors is

explicit unique_ptr( pointer p ) noexcept;

So to create a new std::unique_ptr is to pass a pointer to its constructor.

unique_ptr<int> uptr (new int(3));

Or it is the same as

int *int_ptr = new int(3);
std::unique_ptr<int> uptr (int_ptr);

The different is you don't have to clean up after using it. If you don't use std::unique_ptr (smart pointer), you will have to delete it like this

delete int_ptr;

when you no longer need it or it will cause a memory leak.

Yes: TIME_CREATED contains a date and a time. Use TRUNC to strip the time:

SELECT EMP_NAME, DEPT
FROM EMPLOYEE
WHERE TRUNC(TIME_CREATED) = TO_DATE('26/JAN/2011','dd/mon/yyyy')

UPDATE:
As Dave Costa points out in the comment below, this will prevent Oracle from using the index of the column TIME_CREATED if it exists. An alternative approach without this problem is this:

SELECT EMP_NAME, DEPT
FROM EMPLOYEE
WHERE TIME_CREATED >= TO_DATE('26/JAN/2011','dd/mon/yyyy') 
      AND TIME_CREATED < TO_DATE('26/JAN/2011','dd/mon/yyyy') + 1

According to Google Android Development guide, the variable scope should be limited. Please check this link:

Limit Variable Scope

Your "listen" directives are wrong. See this page: http://nginx.org/en/docs/http/server_names.html.

They should be

server {
    listen      80;
    server_name www.domain1.com;
    root /var/www/domain1;
}

server {
    listen       80;
    server_name www.domain2.com;
    root /var/www/domain2;
}

Note, I have only included the relevant lines. Everything else looked okay but I just deleted it for clarity. To test it you might want to try serving a text file from each server first before actually serving php. That's why I left the 'root' directive in there.

Suppose you have two commits in local branch:

      D---E master
     /
A---B---C---F origin/master

After "git pull", will be:

      D--------E  
     /          \
A---B---C---F----G   master, origin/master

After "git pull --rebase", there will be no merge point G. Note that D and E become different commits:

A---B---C---F---D'---E'   master, origin/master

My solution, with manipulation of strings (not the fastest, but is compact):

public enum State {
    NEW,
    RUNNABLE,
    BLOCKED,
    WAITING,
    TIMED_WAITING,
    TERMINATED;

    public static String[] names() {
        String valuesStr = Arrays.toString(State.values());
        return valuesStr.substring(1, valuesStr.length()-1).replace(" ", "").split(",");
    }
}

Finally, the latest node.js release v10.3.0 has natively supported fs promises.

const fsPromises = require('fs').promises; // or require('fs/promises') in v10.0.0
fsPromises.writeFile(ASIN + '.json', JSON.stringify(results))
  .then(() => {
    console.log('JSON saved');
  })
  .catch(er => {
    console.log(er);
  });

You can check the official documentation for more details. https://nodejs.org/api/fs.html#fs_fs_promises_api

The Boa is good for your needs, see the example which extends Python tensorflow keras.Sequential class in JavaScript.

const fs = require('fs');
const boa = require('@pipcook/boa');
const { tuple, enumerate } = boa.builtins();

const tf = boa.import('tensorflow');
const tfds = boa.import('tensorflow_datasets');

const { keras } = tf;
const { layers } = keras;

const [
  [ train_data, test_data ],
  info
] = tfds.load('imdb_reviews/subwords8k', boa.kwargs({
  split: tuple([ tfds.Split.TRAIN, tfds.Split.TEST ]),
  with_info: true,
  as_supervised: true
}));

const encoder = info.features['text'].encoder;
const padded_shapes = tuple([
  [ null ], tuple([])
]);
const train_batches = train_data.shuffle(1000)
  .padded_batch(10, boa.kwargs({ padded_shapes }));
const test_batches = test_data.shuffle(1000)
  .padded_batch(10, boa.kwargs({ padded_shapes }));

const embedding_dim = 16;
const model = keras.Sequential([
  layers.Embedding(encoder.vocab_size, embedding_dim),
  layers.GlobalAveragePooling1D(),
  layers.Dense(16, boa.kwargs({ activation: 'relu' })),
  layers.Dense(1, boa.kwargs({ activation: 'sigmoid' }))
]);

model.summary();
model.compile(boa.kwargs({
  optimizer: 'adam',
  loss: 'binary_crossentropy',
  metrics: [ 'accuracy' ]
}));

The complete example is at: https://github.com/alibaba/pipcook/blob/master/example/boa/tf2/word-embedding.js

I used Boa in another project Pipcook, which is to address the machine learning problems for JavaScript developers, we implemented ML/DL models upon the Python ecosystem(tensorflow,keras,pytorch) by the boa library.

By subquery, it should work:

    SELECT distinct(Category) from MonitoringJob  where Category in(select Category from MonitoringJob order by CreationDate desc);

I'd use standard javascript:

for (var m in myMap){
    for (var i=0;i<myMap[m].length;i++){
    ... do something with myMap[m][i] ...
    }
} 

Note the different ways of treating objects and arrays.

 arrList.set(5,newValue);

and if u want to update it then add this line also

 youradapater.NotifyDataSetChanged();

Take care to strip out newlines from any string you pass to setData(). Otherwise an exception gets thrown.

Also note that even if you do that, then subsequently get that data again using getData(), CKEditor puts the line breaks back in.

FirstOrDefault or SingleOrDefault might be useful, depending on your scenario, and whether you want to handle there being zero or more than one matches:

FirstOrDefault: Returns the first element of a sequence, or a default value if no element is found.

SingleOrDefault: Returns the only element of a sequence, or a default value if the sequence is empty; this method throws an exception if there is more than one element in the sequence

I don't know how this works in a linq 'from' query but in lambda syntax it looks like this:

var item1 = Items.FirstOrDefault(x => x.Id == 123);
var item2 = Items.SingleOrDefault(x => x.Id == 123);

I wanted something where I have access to base64 value to store into a list and for me adding event listener worked. You just need the FileReader which will read the image blob and return the base64 in the result.

createImageFromBlob(image: Blob) {
    const reader = new FileReader();
    const supportedImages = []; // you can also refer to some global variable
    reader.addEventListener(
      'load',
      () => {
        // reader.result will have the required base64 image
        const base64data = reader.result;
        supportedImages.push(base64data); // this can be a reference to global variable and store the value into that global list so as to use it in the other part
      },
      false
    );
    // The readAsDataURL method is used to read the contents of the specified Blob or File.
    if (image) {
      reader.readAsDataURL(image);
    }
 }

Final part is the readAsDataURL which is very important is being used to read the content of the specified Blob

Main advantage for me is that Sublime Text 2 is almost the same, and has the same features on Windows, Linux and OS X. Can you claim that about Notepad++? It makes me move from one OS to another seamlessly.

Then there is speed. Sublime Text 2, which people claim is buggy and unstable ( 3 is more stable ), is still amazingly fast. If you use it, you will realize how fast it is.

Sublime Text 2 has some neat features like multi cursor input, multiple selections etc that will make you immensely productive.

Good number of plugins and themes, and also support for those of Textmate means you can do anything with Sublime Text 2. I have moved from Notepad++ to Sublime Text 2 on Windows and haven't looked back. The real question for me has been - Sublime Text 2 or vim?

What's good on Notepad++ side - it loads much faster on Windows for me. Maybe it will be good enough for you for quick editing. But, again, Sublime Text 3 is supposed to be faster on this front too. Sublime text 2 is not really good when it comes to handling huge files, and I had found that Notepad++ was pretty good till certain size of files. And, of course, Notepad++ is free. Sublime Text 2 has unlimited trial.

xmltodict (full disclosure: I wrote it) can help you convert your XML to a dict+list+string structure, following this "standard". It is Expat-based, so it's very fast and doesn't need to load the whole XML tree in memory.

Once you have that data structure, you can serialize it to JSON:

import xmltodict, json

o = xmltodict.parse('<e> <a>text</a> <a>text</a> </e>')
json.dumps(o) # '{"e": {"a": ["text", "text"]}}'

CommonJS modules allow two ways to define exported properties. In either case you are returning an Object/Function. Because functions are first class citizens in JavaScript they to can act just like Objects (technically they are Objects). That said your question about using the new keywords has a simple answer: Yes. I'll illustrate...

Module exports

You can either use the exports variable provided to attach properties to it. Once required in another module those assign properties become available. Or you can assign an object to the module.exports property. In either case what is returned by require() is a reference to the value of module.exports.

A pseudo-code example of how a module is defined:

var theModule = {
  exports: {}
};

(function(module, exports, require) {

  // Your module code goes here

})(theModule, theModule.exports, theRequireFunction);

In the example above module.exports and exports are the same object. The cool part is that you don't see any of that in your CommonJS modules as the whole system takes care of that for you all you need to know is there is a module object with an exports property and an exports variable that points to the same thing the module.exports does.

Require with constructors

Since you can attach a function directly to module.exports you can essentially return a function and like any function it could be managed as a constructor (That's in italics since the only difference between a function and a constructor in JavaScript is how you intend to use it. Technically there is no difference.)

So the following is perfectly good code and I personally encourage it:

// My module
function MyObject(bar) {
  this.bar = bar;
}

MyObject.prototype.foo = function foo() {
  console.log(this.bar);
};

module.exports = MyObject;

// In another module:
var MyObjectOrSomeCleverName = require("./my_object.js");
var my_obj_instance = new MyObjectOrSomeCleverName("foobar");
my_obj_instance.foo(); // => "foobar"

Require for non-constructors

Same thing goes for non-constructor like functions:

// My Module
exports.someFunction = function someFunction(msg) {
  console.log(msg);
}

// In another module
var MyModule = require("./my_module.js");
MyModule.someFunction("foobar"); // => "foobar"

We don't have this problem if we are testing our client request with localhost destination address (host or hostname on node.js) and our server common name is CN = localhost in the server cert. But even if we change localhost for 127.0.0.1 or any other IP we'll get error Hostname/IP doesn't match certificate's altnames on node.js or SSL handshake failed on QT.

I had the same issue about my server certificate on my client request. To solve it on my client node.js app I needed to put a subjectAltName on my server_extension with the following value:

[ server_extension ]
       .
       .
       .

subjectAltName          = @alt_names_server

[alt_names_server]
IP.1 = x.x.x.x

and then I use -extension when I create and sign the certificate.

example:

In my case, I first export the issuer's config file because this file contents the server_extension:

export OPENSSL_CONF=intermed-ca.cnf

so I create and sign my server cert:

openssl ca \
    -in server.req.pem \
    -out server.cert.pem \
    -extensions server_extension \
    -startdate `date +%y%m%d000000Z -u -d -2day` \
    -enddate `date +%y%m%d000000Z -u -d +2years+1day`   

It works fine on clients based on node.js with https requests but it doesn't work with clients based on QT QSsl when we define sslConfiguration.setPeerVerifyMode(QSslSocket::VerifyPeer), unless we use QSslSocket::VerifyNone it won't work. If we use VerifyNone it will make our app to don't check the peer certificate so it'll accept any cert. So, to solve it I need to change my server common name on its cert and replace its value for the IP Address where my server is running.

for example:

CN = 127.0.0.1

However, will it automatically remove these committed files from the repository?

No. Even with an existing .gitignore you are able to stage "ignored" files with the -f (force) flag. If they files are already commited, they don't get removed automatically.

git rm --cached path/to/ignored.exe

This seems to work:

I think the first option is better because you are going to access the values as a['a'] or a['another']. The keys in your dictionary are strings, and there is no reason to pretend they are not. To me the keyword syntax looks clever at first, but obscure at a second look. This only makes sense to me if you are working with __dict__, and the keywords are going to become attributes later, something like that.

As others have noted, in order for a jar file to be executable, the application's entry point must be set in the Main-Class attribute of the manifest file. If the dependency class files are not collocated, then they need to be set in the Class-Path entry of the manifest file.

I have tried all kinds of plugin combinations and what not for the simple task of creating an executable jar and somehow someway, include the dependencies. All plugins seem to be lacking one way or another, but finally I got it like I wanted. No mysterious scripts, not a million different mini files polluting the build directory, a pretty clean build script file, and above all: not a million foreign third party class files merged into my jar archive.

The following is a copy-paste from here for your convenience..

[How-to] create a distribution zip file with dependency jars in subdirectory /lib and add all dependencies to Class-Path entry in the manifest file:

apply plugin: 'java'
apply plugin: 'java-library-distribution'

repositories {
    mavenCentral()
}

dependencies {
    compile 'org.apache.commons:commons-lang3:3.3.2'
}

// Task "distZip" added by plugin "java-library-distribution":
distZip.shouldRunAfter(build)

jar {
    // Keep jar clean:
    exclude 'META-INF/*.SF', 'META-INF/*.DSA', 'META-INF/*.RSA', 'META-INF/*.MF'

    manifest {
        attributes 'Main-Class': 'com.somepackage.MainClass',
                   'Class-Path': configurations.runtime.files.collect { "lib/$it.name" }.join(' ')
    }
    // How-to add class path:
    //     https://stackoverflow.com/questions/22659463/add-classpath-in-manifest-using-gradle
    //     https://gist.github.com/simon04/6865179
}

Hosted as a gist here.

The result can be found in build/distributions and the unzipped contents look like this:

lib/commons-lang3-3.3.2.jar
MyJarFile.jar

Contents of MyJarFile.jar#META-INF/MANIFEST.mf:

Manifest-Version: 1.0
Main-Class: com.somepackage.MainClass
Class-Path: lib/commons-lang3-3.3.2.jar

I have a really stupid use case for why I got this error. Originally I was printing my data > file.txt

Then I changed my mind, and decided to use open("file.txt", "w") instead. But when I called python, I left > file.txt .....

string1.equals(string2) is the way.

It returns true if string1 is equals to string2 in value. Else, it will return false.

equals reference

I found this table super useful for deciding when to use different types of Contexts:

1. An application CAN start an Activity from here, but it requires that a new task be created. This may fit specific use cases, but can create non-standard back stack behaviors in your application and is generally not recommended or considered good practice.
2. This is legal, but inflation will be done with the default theme for the system on which you are running, not what’s defined in your application.
3. Allowed if the receiver is null, which is used for obtaining the current value of a sticky broadcast, on Android 4.2 and above.

This happens because java does not provide with Servlet-api.jar to import directly, so you need to import it externally like from Tomcat , for this we need to provide the classpath of lib folder from which we will be importing the Servlet and it's related Classes.

For Windows you can apply this method:

1. open command prompt
2. type

 javac -classpath "C:\Program Files\Apache Software Foundation\Tomcat 9.0\lib\*;" YourFileName.java 
     

3. It will take all jar files which needed for importing Servlet, HttpServlet ,etc and compile your java file.

4. You can add multiple classpaths Eg.

javac -classpath "C:\Users\Project1\WEB-INF\lib\*; C:\Program Files\Apache Software Foundation\Tomcat 9.0\lib\*;" YourFileName.java

I used this and in worked for me!

I recommend Logo (aka the turtle) to get the basic concepts down. It provides a good sandbox with immediate graphical feedback, and you can demostrate loops, variables, functions, conditionals, etc. This page provides an excellent tutorial.

After Logo, move to Python or Ruby. I recommend Python, as it's based on ABC, which was invented for the purpose of teaching programming.

When teaching programming, I must second EHaskins's suggestion of simple projects and then complex projects. The best way to learn is to start with a definite outcome and a measurable milestone. It keeps the lessons focused, allows the student to build skills and then build on those skills, and gives the student something to show off to friends. Don't underestimate the power of having something to show for one's work.

Theoretically, you can stick with Python, as Python can do almost anything. It's a good vehicle to teach object-oriented programming and (most) algorithms. You can run Python in interactive mode like a command line to get a feel for how it works, or run whole scripts at once. You can run your scripts interpreted on the fly, or compile them into binaries. There are thousands of modules to extend the functionality. You can make a graphical calculator like the one bundled with Windows, or you can make an IRC client, or anything else.

XKCD describes Python's power a little better:

You can move to C# or Java after that, though they don't offer much that Python doesn't already have. The benefit of these is that they use C-style syntax, which many (dare I say most?) languages use. You don't need to worry about memory management yet, but you can get used to having a bit more freedom and less handholding from the language interpreter. Python enforces whitespace and indenting, which is nice most of the time but not always. C# and Java let you manage your own whitespace while remaining strongly-typed.

From there, the standard is C or C++. The freedom in these languages is almost existential. You are now in charge of your own memory management. There is no garbage collection to help you. This is where you teach the really advanced algorithms (like mergesort and quicksort). This is where you learn why "segmentation fault" is a curse word. This is where you download the source code of the Linux kernel and gaze into the Abyss. Start by writing a circular buffer and a stack for string manipulation. Then work your way up.

If your iPhone is jailbroken you can use DemoGod

 function convertDatePickerTimeToMySQLTime(str) {
        var month, day, year, hours, minutes, seconds;
        var date = new Date(str),
            month = ("0" + (date.getMonth() + 1)).slice(-2),
            day = ("0" + date.getDate()).slice(-2);
        hours = ("0" + date.getHours()).slice(-2);
        minutes = ("0" + date.getMinutes()).slice(-2);
        seconds = ("0" + date.getSeconds()).slice(-2);

        var mySQLDate = [date.getFullYear(), month, day].join("-");
        var mySQLTime = [hours, minutes, seconds].join(":");
        return [mySQLDate, mySQLTime].join(" ");
    }

No.

You want to use: .indexOf("foo") and then check the index. If it's >= 0, it contains that string.

it's pretty painless to pop a couple methods in a file that will handle asynchronous data in a serialized order and give a more conventional flavour to your code. For example:

module.exports = function () {
  var self = this;

  this.each = async (items, fn) => {
    if (items && items.length) {
      await Promise.all(
        items.map(async (item) => {
          await fn(item);
        }));
    }
  };

  this.reduce = async (items, fn, initialValue) => {
    await self.each(
      items, async (item) => {
        initialValue = await fn(initialValue, item);
      });
    return initialValue;
  };
};

now, assuming that's saved at './myAsync.js' you can do something similar to the below in an adjacent file:

...
/* your server setup here */
...
var MyAsync = require('./myAsync');
var Cat = require('./models/Cat');
var Doje = require('./models/Doje');
var example = async () => {
  var myAsync = new MyAsync();
  var doje = await Doje.findOne({ name: 'Doje', noises: [] }).save();
  var cleanParams = [];

  // FOR EACH EXAMPLE
  await myAsync.each(['bork', 'concern', 'heck'], 
    async (elem) => {
      if (elem !== 'heck') {
        await doje.update({ $push: { 'noises': elem }});
      }
    });

  var cat = await Cat.findOne({ name: 'Nyan' });

  // REDUCE EXAMPLE
  var friendsOfNyanCat = await myAsync.reduce(cat.friends,
    async (catArray, friendId) => {
      var friend = await Friend.findById(friendId);
      if (friend.name !== 'Long cat') {
        catArray.push(friend.name);
      }
    }, []);
  // Assuming Long Cat was a friend of Nyan Cat...
  assert(friendsOfNyanCat.length === (cat.friends.length - 1));
}

The default restart policy is no.

For the created containers use docker update to update restart policy.

docker update --restart=always 0576df221c0b

0576df221c0b is the container id.

Unfortunately, you have a malformed url query string, so a regex technique is most appropriate. See what I mean.

There is no need for capture groups. Just match id= then forget those characters with \K, then isolate the following one or more digital characters.

Code (Demo)

$str = 'producturl.php?id=736375493?=tm';
echo preg_match('~id=\K\d+~', $str, $out) ? $out[0] : 'no match';

Output:

736375493

Also check if all dirs which you wrote in the my.ini exists.

My problem was that tmpdir doeesn`t exist so MySQL daemon falls with error 1067.

[mysqld]
port= 3306
tmpdir = "C:/tmp"

In this case C:/tmp must exists.

To make more than one element fade in/out sequentially such as 5 elements fade each 4s,

1- make unique animation for each element with animation-duration equal to [ 4s (duration for each element) * 5 (number of elements) ] = 20s

animation-name: anim1 , anim2, anim3 ... 
animation-duration : 20s, 20s, 20s ... 

2- get animation keyframe for each element.

100% (keyframes percentage) / 5 (elements) = 20% (frame for each element)

3- define starting and ending point for each animation:

each animation has 20% frame length and @keyframes percentage always starts from 0%, so first animation will start from 0% and end in his frame(20%), and each next animation will starts from previous animation ending point and end when it reach his frame (+20% ),

@keyframes animation1 { 0% {}, 20% {}}
@keyframes animation2 { 20% {}, 40% {}}
@keyframes animation3 { 40% {}, 60% {}}
and so on

now we need to make each animation fade in from 0 to 1 opacity and fade out from 1 to 0,

so we will add another 2 points (steps) for each animation after starting and before ending point to handle the full opacity(1)

std::string str(buffer, buffer + length);

Or, if the string already exists:

str.assign(buffer, buffer + length);

Edit: I'm still not completely sure I understand the question. But if it's something like what JoshG is suggesting, that you want up to length characters, or until a null terminator, whichever comes first, then you can use this:

std::string str(buffer, std::find(buffer, buffer + length, '\0'));

Advantages: saves server CPU, needs no adjustments in your app.

Looking at it from a practical rather than theoretical standpoint, on a 32 bit Windows system, the maximum total amount of memory available for a single process is 2 GB. You can break the limit by going to a 64 bit operating system with much more physical memory, but whether to do this or look for alternatives depends very much on your intended users and their budgets. You can also extend it somewhat using PAE.

The type of the array is very important, as default structure alignment on many compilers is 8 bytes, which is very wasteful if memory usage is an issue. If you are using Visual C++ to target Windows, check out the #pragma pack directive as a way of overcoming this.

Another thing to do is look at what in memory compression techniques might help you, such as sparse matrices, on the fly compression, etc... Again this is highly application dependent. If you edit your post to give some more information as to what is actually in your arrays, you might get more useful answers.

Edit: Given a bit more information on your exact requirements, your storage needs appear to be between 7.6 GB and 76 GB uncompressed, which would require a rather expensive 64 bit box to store as an array in memory in C++. It raises the question why do you want to store the data in memory, where one presumes for speed of access, and to allow random access. The best way to store this data outside of an array is pretty much based on how you want to access it. If you need to access array members randomly, for most applications there tend to be ways of grouping clumps of data that tend to get accessed at the same time. For example, in large GIS and spatial databases, data often gets tiled by geographic area. In C++ programming terms you can override the [] array operator to fetch portions of your data from external storage as required.

You can use Class#getDeclaredFields() to get all declared fields of the class. You can use Field#get() to get the value.

In short:

Object someObject = getItSomehow();
for (Field field : someObject.getClass().getDeclaredFields()) {
    field.setAccessible(true); // You might want to set modifier to public first.
    Object value = field.get(someObject); 
    if (value != null) {
        System.out.println(field.getName() + "=" + value);
    }
}

To learn more about reflection, check the Sun tutorial on the subject.

That said, the fields does not necessarily all represent properties of a VO. You would rather like to determine the public methods starting with get or is and then invoke it to grab the real property values.

for (Method method : someObject.getClass().getDeclaredMethods()) {
    if (Modifier.isPublic(method.getModifiers())
        && method.getParameterTypes().length == 0
        && method.getReturnType() != void.class
        && (method.getName().startsWith("get") || method.getName().startsWith("is"))
    ) {
        Object value = method.invoke(someObject);
        if (value != null) {
            System.out.println(method.getName() + "=" + value);
        }
    }
}

That in turn said, there may be more elegant ways to solve your actual problem. If you elaborate a bit more about the functional requirement for which you think that this is the right solution, then we may be able to suggest the right solution. There are many, many tools available to massage javabeans.

you need to add a little hack to achieve this.

You can hide a file upload(input type=file) behind your button.

and onclick of your button you can trigger your file upload click.

It will open a file upload window on click of button

<button id="btnfile"> 
 <img src='".$cfet['productimage']."' width='50' height='40'>
</button> 
<div class="wrapper"> //set wrapper `display:hidden`
     <input type="file" id="uploadfile" /> 
</div>

and some javascript

$("#btnfile").click(function () {
    $("#uploadfile").click();
});

here is a fiddle for this example: http://jsfiddle.net/ravi441988/QmyHV/1/embedded/result/

You may use this :

Download "angular-post-fix": "^0.1.0"

Then add 'httpPostFix' to your dependencies while declaring the angular module.

This is a very simple way of doing it with no functionality and all visual effect,

Use a grid and just simply customise it.

<Grid Background="DodgerBlue" Height="250" Width="1" VerticalAlignment="Center" Margin="5,0,5,0"/>

Just another way to do it.

If the above method does not work then make sure you update it in Dispatch.main.async{} block. You do not need to call layoutIfNeeded() method then.

As to me, i need to caffe to my python path. I can add it's path to the file /home/xy/.bashrc by add

export PYTHONPATH=/home/xy/caffe-master/python:$PYTHONPATH.

to my /home/xy/.bashrc file.

But when I use pycharm, the path is still not in.

So I can add path to PYTHONPATH variable, by run -> edit Configuration.

I use the following with python 3.8

string4 = f'{string1}{string2}{string3}'

Converting VARCHAR2 to CLOB

In PL/SQL a CLOB can be converted to a VARCHAR2 with a simple assignment, SUBSTR, and other methods. A simple assignment will only work if the CLOB is less then or equal to the size of the VARCHAR2. The limit is 32767 in PL/SQL and 4000 in SQL (although 12c allows 32767 in SQL).

For example, this code converts a small CLOB through a simple assignment and then coverts the beginning of a larger CLOB.

declare
    v_small_clob clob := lpad('0', 1000, '0');
    v_large_clob clob := lpad('0', 32767, '0') || lpad('0', 32767, '0');
    v_varchar2   varchar2(32767);
begin
    v_varchar2 := v_small_clob;
    v_varchar2 := substr(v_large_clob, 1, 32767);
end;

LONG?

The above code does not convert the value to a LONG. It merely looks that way because of limitations with PL/SQL debuggers and strings over 999 characters long.

For example, in PL/SQL Developer, open a Test window and add and debug the above code. Right-click on v_varchar2 and select "Add variable to Watches". Step through the code and the value will be set to "(Long Value)". There is a ... next to the text but it does not display the contents.

C#?

I suspect the real problem here is with C# but I don't know how enough about C# to debug the problem.

Javascript does not have interfaces. But it can be duck-typed, an example can be found here:

I have used Excel.dll library which is:

• open source
• lightweight
• fast
• compatible with xls and xlsx

The documentation available over here: https://exceldatareader.codeplex.com/

Strongly recommendable.

Try this in your .htaccess:

.htaccess

ErrorDocument 404 http://example.com/404/
ErrorDocument 500 http://example.com/500/
# or map them to one error document:
# ErrorDocument 404 /pages/errors/error_redirect.php
# ErrorDocument 500 /pages/errors/error_redirect.php

RewriteEngine On
RewriteBase /

RewriteCond %{REQUEST_URI} ^/404/$
RewriteRule ^(.*)$ /pages/errors/404.php [L]

RewriteCond %{REQUEST_URI} ^/500/$
RewriteRule ^(.*)$ /pages/errors/500.php [L]

# or map them to one error document:
#RewriteCond %{REQUEST_URI} ^/404/$ [OR]
#RewriteCond %{REQUEST_URI} ^/500/$
#RewriteRule ^(.*)$ /pages/errors/error_redirect.php [L]

The ErrorDocument redirects all 404s to a specific URL, all 500s to another url (replace with your domain).

The Rewrite rules map that URL to your actual 404.php script. The RewriteCond regular expressions can be made more generic if you want, but I think you have to explicitly define all ErrorDocument codes you want to override.

Local Redirect:

Change .htaccess ErrorDocument to a file that exists (must exist, or you'll get an error):

ErrorDocument 404 /pages/errors/404_redirect.php

404_redirect.php

<?php
   header('Location: /404/');
   exit;
?>

Redirect based on error number

Looks like you'll need to specify an ErrorDocument line in .htaccess for every error you want to redirect (see: Apache ErrorDocument and Apache Custom Error). The .htaccess example above has multiple examples in it. You can use the following as the generic redirect script to replace 404_redirect.php above.

error_redirect.php

<?php
   $error_url = $_SERVER["REDIRECT_STATUS"] . '/';
   $error_path = $error_url . '.php';

   if ( ! file_exists($error_path)) {
      // this is the default error if a specific error page is not found
      $error_url = '404/';
   }

   header('Location: ' . $error_url);
   exit;
?>

https://translate.google.com.vn/translate_tts?ie=UTF-8&q=%E0%A6%86%E0%A6%AE%E0%A6%BF%20%E0%A6%A4%E0%A7%8B%E0%A6%AE%E0%A6%BE%E0%A6%AF%E0%A6%BC%20%E0%A6%AD%E0%A6%BE%E0%A6%B2%E0%A7%8B%E0%A6%AC%E0%A6%BE%E0%A6%B8%E0%A6%BF+&tl=bn&client=tw-ob

You can use .length, like this:

var count = $("ul li").length;

.length tells how many matches the selector found, so this counts how many <li> under <ul> elements you have...if there are sub-children, use "ul > li" instead to get only direct children. If you have other <ul> elements in your page, just change the selector to match only his one, for example if it has an ID you'd use "#myListID > li".

In other situations where you don't know the child type, you can use the * (wildcard) selector, or .children(), like this:

var count = $(".parentSelector > *").length;

or:

var count = $(".parentSelector").children().length;

Here is a simple function which does exactly this :

#include <windows.h>
#include <string>

bool dirExists(const std::string& dirName_in)
{
  DWORD ftyp = GetFileAttributesA(dirName_in.c_str());
  if (ftyp == INVALID_FILE_ATTRIBUTES)
    return false;  //something is wrong with your path!

  if (ftyp & FILE_ATTRIBUTE_DIRECTORY)
    return true;   // this is a directory!

  return false;    // this is not a directory!
}

Provided that the remote repository is origin, and that you're interested in master:

git fetch origin
git reset --hard origin/master

This tells it to fetch the commits from the remote repository, and position your working copy to the tip of its master branch.

All your local commits not common to the remote will be gone.

You need the javax.mail.jar library. Download it from the Java EE JavaMail GitHub page and add it to your IntelliJ project:

1. Download javax.mail.jar
2. Navigate to File > Project Structure...
3. Go to the Libraries tab
4. Click on the + button (Add New Project Library)
5. Browse to the javax.mail.jar file
6. Click OK to apply the changes

I created my own little lazy Math-Object for degree (MathD), hope it helps:

//helper
/**
 * converts degree to radians
 * @param degree
 * @returns {number}
 */
var toRadians = function (degree) {
    return degree * (Math.PI / 180);
};

/**
 * Converts radian to degree
 * @param radians
 * @returns {number}
 */
var toDegree = function (radians) {
    return radians * (180 / Math.PI);
}

/**
 * Rounds a number mathematical correct to the number of decimals
 * @param number
 * @param decimals (optional, default: 5)
 * @returns {number}
 */
var roundNumber = function(number, decimals) {
    decimals = decimals || 5;
    return Math.round(number * Math.pow(10, decimals)) / Math.pow(10, decimals);
}
//the object
var MathD = {
    sin: function(number){
        return roundNumber(Math.sin(toRadians(number)));
    },
    cos: function(number){
        return roundNumber(Math.cos(toRadians(number)));
    },
    tan: function(number){
        return roundNumber(Math.tan(toRadians(number)));
    },
    asin: function(number){
        return roundNumber(toDegree(Math.asin(number)));
    },
    acos: function(number){
       return roundNumber(toDegree(Math.acos(number)));
   },
   atan: function(number){
       return roundNumber(toDegree(Math.atan(number)));
   }
};

Its better if you can have RDM (Redis Desktop Manager). You can connect to your redis server by creating a new connection in RDM.

Once its connected you can check the live data, also you can play around with any redis command.

Opening a cli in RDM.

1) Right click on the connection you will see a console option, just click on it a new console window will open at the bottom of RDM.

Coming back to your question FLUSHALL is the command, you can simply type FLUSHALL in the redis cli.

Moreover if you want to know about any redis command and its proper usage, go to link below. https://redis.io/commands.

No, there is no chance to do that. You just learned how important a backup can be.

I'm sorry I don't have enough reputation to comment the "answer" of "Andres Jaan Tack".

I think my messege will be deleted (( But I just want to warn "lurscher" and others who got the same error: be carefull doing

$ mkdir include
$ mv common include
$ git rm -r common
$ git add include/common

It may cause you will not see the git history of your project in new folder.

I tryed

$ git mv oldFolderName newFolderName

got

fatal: bad source, source=oldFolderName/somepath/__init__.py, dest
ination=ESWProj_Base/ESWProj_DebugControlsMenu/somepath/__init__.py

I did

git rm -r oldFolderName

and

git add newFolderName

and I don't see old git history in my project. At least my project is not lost. Now I have my project in newFolderName, but without the history (

Just want to warn, be carefull using advice of "Andres Jaan Tack", if you dont want to lose your git hsitory.

When page IsPostback, the following code work correctly. But when page first loading, there is not multiple newline in the textarea. Bug

textBox1.Text = "Line1\r\n\r\n\r\nLine2";

One of the JPA ways for getting only particular columns is to ask for a Tuple object.

In your case you would need to write something like this:

CriteriaQuery<Tuple> cq = builder.createTupleQuery();
// write the Root, Path elements as usual
Root<EntityClazz> root = cq.from(EntityClazz.class);
cq.multiselect(root.get(EntityClazz_.ID), root.get(EntityClazz_.VERSION));  //using metamodel
List<Tuple> tupleResult = em.createQuery(cq).getResultList();
for (Tuple t : tupleResult) {
    Long id = (Long) t.get(0);
    Long version = (Long) t.get(1);
}

Another approach is possible if you have a class representing the result, like T in your case. T doesn't need to be an Entity class. If T has a constructor like:

public T(Long id, Long version)

then you can use T directly in your CriteriaQuery constructor:

CriteriaQuery<T> cq = builder.createQuery(T.class);
// write the Root, Path elements as usual
Root<EntityClazz> root = cq.from(EntityClazz.class);
cq.multiselect(root.get(EntityClazz_.ID), root.get(EntityClazz_.VERSION));  //using metamodel
List<T> result = em.createQuery(cq).getResultList();

See this link for further reference.

You can simply use this:

'07311954' in df.date.values which returns True or False

Here is the further explanation:

In pandas, using in check directly with DataFrame and Series (e.g. val in df or val in series ) will check whether the val is contained in the Index.

BUT you can still use in check for their values too (instead of Index)! Just using val in df.col_name.values or val in series.values. In this way, you are actually checking the val with a Numpy array.

And .isin(vals) is the other way around, it checks whether the DataFrame/Series values are in the vals. Here vals must be set or list-like. So this is not the natural way to go for the question.

Create a .o file:

g++ -c header.cpp

add this file to a library, creating library if necessary:

ar rvs header.a header.o

use library:

g++ main.cpp header.a

Your question is not very clear, but if you want to include the php file (add the source of that page to yours), you just have to do following :

if(condition){
    $someVar=someValue;
    include "myFile.php";
}

As long as the variable is named $someVar in the myFile.php

Thanks a lot for the first answer.

As for me, I had just one problem with it. When inflating my view, i had a bug : java.lang.NoSuchMethodException : MyView(Context, Attributes)

I resolved it by creating a new constructor :

public MyView(Context context, AttributeSet attrs) {
     super(context, attrs);
     // some code
}

Hope this will help !

Why not just add Labels to the top of the Listbox and if changes are needed, the only thing you need to programmatically change are the labels.

You need to start your Apache Server normally you should have an xampp icon in the info-section from the taskbar, with this tool you can start the apache server as wel as the mysql database (if you need it)

This works for me:

<input type='submit' name='self' value='This window' onclick='this.form.target="_self";' />

<input type='submit' name='blank' value='New window' onclick='this.form.target="_blank";' />

Java is a call by value

How it works

• You always pass a copy of the bits of the value of the reference!

• If it's a primitive data type these bits contain the value of the primitive data type itself, That's why if we change the value of header inside the method then it does not reflect the changes outside.

• If it's an object data type like Foo foo=new Foo() then in this case copy of the address of the object passes like file shortcut , suppose we have a text file abc.txt at C:\desktop and suppose we make shortcut of the same file and put this inside C:\desktop\abc-shortcut so when you access the file from C:\desktop\abc.txt and write 'Stack Overflow' and close the file and again you open the file from shortcut then you write ' is the largest online community for programmers to learn' then total file change will be 'Stack Overflow is the largest online community for programmers to learn' which means it doesn't matter from where you open the file , each time we were accessing the same file , here we can assume Foo as a file and suppose foo stored at 123hd7h(original address like C:\desktop\abc.txt ) address and 234jdid(copied address like C:\desktop\abc-shortcut which actually contains the original address of the file inside) .. So for better understanding make shortcut file and feel.

If you want to format it with manually set symbols, use this:

DecimalFormatSymbols decimalFormatSymbols = new DecimalFormatSymbols();
decimalFormatSymbols.setDecimalSeparator('.');
decimalFormatSymbols.setGroupingSeparator(',');
DecimalFormat decimalFormat = new DecimalFormat("#,##0.00", decimalFormatSymbols);
System.out.println(decimalFormat.format(1237516.2548)); //1,237,516.25

Locale-based formatting is preferred, though.

To trim any set of characters from the beginning and end of a string, you can do the following code where @TrimPattern defines the characters to be trimmed. In this example, Space, tab, LF and CR characters are being trimmed:

Declare @Test nvarchar(50) = Concat (' ', char(9), char(13), char(10), ' ', 'TEST', ' ', char(9), char(10), char(13),' ', 'Test', ' ', char(9), ' ', char(9), char(13), ' ')

DECLARE @TrimPattern nvarchar(max) = '%[^ ' + char(9) + char(13) + char(10) +']%'

SELECT SUBSTRING(@Test, PATINDEX(@TrimPattern, @Test), LEN(@Test) - PATINDEX(@TrimPattern, @Test) - PATINDEX(@TrimPattern, LTRIM(REVERSE(@Test))) + 2)

The scrolling effect is cause by specifying the generic 'background' property in your css instead of the more specific background-image. By setting the background property, the animation will transition between all properties.. Background-Color, Background-Image, Background-Position.. Etc Thus causing the scrolling effect..

E.g.

a {
-webkit-transition-property: background-image 300ms ease-in 200ms;
-moz-transition-property: background-image 300ms ease-in 200ms;
-o-transition-property: background-image 300ms ease-in 200ms;
transition: background-image 300ms ease-in 200ms;
}

Look at SELECT INTO. This will create a new table for you, which can be temporary if you want by prefixing the table name with a pound sign (#).

For example, you can do:

SELECT * 
INTO #YourTempTable
FROM YourReportQuery

Just a supplement here.

The following question is that what if I want more subplots in the figure?

As mentioned in the Doc, we can use fig = plt.subplots(nrows=2, ncols=2) to set a group of subplots with grid(2,2) in one figure object.

Then as we know, the fig, ax = plt.subplots() returns a tuple, let's try fig, ax1, ax2, ax3, ax4 = plt.subplots(nrows=2, ncols=2) firstly.

ValueError: not enough values to unpack (expected 4, got 2)

It raises a error, but no worry, because we now see that plt.subplots() actually returns a tuple with two elements. The 1st one must be a figure object, and the other one should be a group of subplots objects.

So let's try this again:

fig, [[ax1, ax2], [ax3, ax4]] = plt.subplots(nrows=2, ncols=2)

and check the type:

type(fig) #<class 'matplotlib.figure.Figure'>
type(ax1) #<class 'matplotlib.axes._subplots.AxesSubplot'>

Of course, if you use parameters as (nrows=1, ncols=4), then the format should be:

fig, [ax1, ax2, ax3, ax4] = plt.subplots(nrows=1, ncols=4)

So just remember to keep the construction of the list as the same as the subplots grid we set in the figure.

Hope this would be helpful for you.

The error occurs when trying to run mongo.exe WITHOUT having executed mongod.exe. The following batch script solved the problem:

@echo off
cd C:\mongodb\bin\
start mongod.exe
start mongo.exe
exit

Just solved this in XCode 4.2, none of above helped. The thing was (I'm not sure what actually happened, but, maybe this helps someone): my teammate created new build configurations and updated project in SVN. I had old build configuration set up in Run Scheme settings, so the steps for me were:

1. Product -> Edit Scheme...
2. Select "Run %project_name.app%" (or whatever causes problem)
3. In build configuration combo select that new build configuration from my teammate

And that's all, breakpoints are back again. Hope this helps.

The filter design method in accepted answer is correct, but it has a flaw. SciPy bandpass filters designed with b, a are unstable and may result in erroneous filters at higher filter orders.

Instead, use sos (second-order sections) output of filter design.

from scipy.signal import butter, sosfilt, sosfreqz

def butter_bandpass(lowcut, highcut, fs, order=5):
        nyq = 0.5 * fs
        low = lowcut / nyq
        high = highcut / nyq
        sos = butter(order, [low, high], analog=False, btype='band', output='sos')
        return sos

def butter_bandpass_filter(data, lowcut, highcut, fs, order=5):
        sos = butter_bandpass(lowcut, highcut, fs, order=order)
        y = sosfilt(sos, data)
        return y

Also, you can plot frequency response by changing

b, a = butter_bandpass(lowcut, highcut, fs, order=order)
w, h = freqz(b, a, worN=2000)

to

sos = butter_bandpass(lowcut, highcut, fs, order=order)
w, h = sosfreqz(sos, worN=2000)

This should work pretty nicely. It will never grow beyond the initial size. The toList method will give you the entries in the correct chronological order. This was done in groovy - but converting it to java proper should be pretty easy.

static class FixedSizeCircularReference<T> {
    T[] entries
    FixedSizeCircularReference(int size) {
        this.entries = new Object[size] as T[]
        this.size = size
    }
    int cur = 0
    int size
    void add(T entry) {
        entries[cur++] = entry
        if (cur >= size) {
            cur = 0
        }
    }
    List<T> asList() {
        List<T> list = new ArrayList<>()
        int oldest = (cur == size - 1) ? 0 : cur
        for (int i = 0; i < this.entries.length; i++) {
            def e = this.entries[oldest + i < size ? oldest + i : oldest + i - size]
            if (e) list.add(e)
        }
        return list
    }
}

FixedSizeCircularReference<String> latestEntries = new FixedSizeCircularReference(100)
latestEntries.add('message 1') 
// .....
latestEntries.add('message 1000') 
latestEntries.asList() //Returns list of '100' messages

I know this is very old and possibly talking about an older version of Visual studio and so this might not have been an option before but anyway, my way would be when at a breakpoint use the locals window to see all current variable values ( Debug >> Windows >> Locals )

You can iterate the key/value pairs of the saveData object to build an array of the pairs, then use join("&") on the resulting array:

var a = [];
for (key in saveData) {
    a.push(key+"="+saveData[key]);
}
var serialized = a.join("&") // a=2&c=1

Your code should like this:

<span id="replies">8</span>

var currentValue = $("#replies").text();
var newValue = parseInt(parseFloat(currentValue)) + 1;
$("replies").text(newValue);

Hacks N Tricks

In IIS >= 7, a <webLimits> section has replaced ConnectionTimeout, HeaderWaitTimeout, MaxGlobalBandwidth, and MinFileBytesPerSec IIS 6 metabase settings.

Example Configuration:

<configuration>
   <system.applicationHost>
      <webLimits connectionTimeout="00:01:00"
         dynamicIdleThreshold="150"
         headerWaitTimeout="00:00:30"
         minBytesPerSecond="500"
      />
   </system.applicationHost>
</configuration>

For reference: more information regarding these settings in IIS can be found here. Also, I was unable to add this section to the web.config via the IIS manager's "configuration editor", though it did show up once I added it and searched the configuration.

I found this blog post which explains that it's used to record clicks. Without official word from Google it could be used any number of things.

Can we guarantee it will not die?

As long there is no reference returned, it's perfectly fine to do so. words will be moved to the variable receiving the result.

The local variable will go out of scope. after it was moved (or copied).

In my particular case, I had a similar error on a legacy website used in my organization. To solve the issue, I had to list the website a a "Trusted site".

To do so:

• Click the Tools button, and then Internet options.
• Go on the Security tab.
• Click on Trusted sites and then on the sites button.
• Enter the url of the website and click on Add.

I'm leaving this here in the remote case it will help someone.

There are three parts:

1. Add a 'shebang' at the top of your script which tells how to execute your script
2. Give the script 'run' permissions.
3. Make the script in your PATH so you can run it from anywhere.

Adding a shebang

You need to add a shebang at the top of your script so the shell knows which interpreter to use when parsing your script. It is generally:

#!path/to/interpretter

To find the path to your python interpretter on your machine you can run the command:

which python

This will search your PATH to find the location of your python executable. It should come back with a absolute path which you can then use to form your shebang. Make sure your shebang is at the top of your python script:

#!/usr/bin/python

Run Permissions

You have to mark your script with run permissions so that your shell knows you want to actually execute it when you try to use it as a command. To do this you can run this command:

chmod +x myscript.py

Add the script to your path

The PATH environment variable is an ordered list of directories that your shell will search when looking for a command you are trying to run. So if you want your python script to be a command you can run from anywhere then it needs to be in your PATH. You can see the contents of your path running the command:

echo $PATH

This will print out a long line of text, where each directory is seperated by a semicolon. Whenever you are wondering where the actual location of an executable that you are running from your PATH, you can find it by running the command:

which <commandname>

Now you have two options: Add your script to a directory already in your PATH, or add a new directory to your PATH. I usually create a directory in my user home directory and then add it the PATH. To add things to your path you can run the command:

export PATH=/my/directory/with/pythonscript:$PATH

Now you should be able to run your python script as a command anywhere. BUT! if you close the shell window and open a new one, the new one won't remember the change you just made to your PATH. So if you want this change to be saved then you need to add that command at the bottom of your .bashrc or .bash_profile

Frankly, pretty much everything that we've encountered works just fine w/ the JAXP version, so we always exclude xml-apis and xercesImpl.

One option is to use Outlook. We have a mail manager application that access an exchange server and uses outlook as the interface. Its dirty but it works.

Example code:

public Outlook.MAPIFolder getInbox()
        {
            mailSession = new Outlook.Application();
            mailNamespace = mailSession.GetNamespace("MAPI");
            mailNamespace.Logon(mail_username, mail_password, false, true);
            return MailNamespace.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderInbox);
        }

You can set the s bit for your script so that it does not need sudo and runs as root (and you do not need to write your root password in the script):

sudo chmod +s myscript

Here is the complete code, import pfx, add iis website, add ssl binding:

$SiteName = "MySite"
$HostName = "localhost"
$CertificatePassword = '1234'
$SiteFolder = Join-Path -Path 'C:\inetpub\wwwroot' -ChildPath $SiteName
$certPath = 'c:\cert.pfx'


Write-Host 'Import pfx certificate' $certPath
$certRootStore = “LocalMachine”
$certStore = "My"
$pfx = New-Object System.Security.Cryptography.X509Certificates.X509Certificate2
$pfx.Import($certPath,$CertificatePassword,"Exportable,PersistKeySet") 
$store = New-Object System.Security.Cryptography.X509Certificates.X509Store($certStore,$certRootStore) 
$store.Open('ReadWrite')
$store.Add($pfx) 
$store.Close() 
$certThumbprint = $pfx.Thumbprint


Write-Host 'Add website' $SiteName
New-WebSite -Name $SiteName -PhysicalPath $SiteFolder -Force
$IISSite = "IIS:\Sites\$SiteName"
Set-ItemProperty $IISSite -name  Bindings -value @{protocol="https";bindingInformation="*:443:$HostName"}
if($applicationPool) { Set-ItemProperty $IISSite -name  ApplicationPool -value $IISApplicationPool }


Write-Host 'Bind certificate with Thumbprint' $certThumbprint
$obj = get-webconfiguration "//sites/site[@name='$SiteName']"
$binding = $obj.bindings.Collection[0]
$method = $binding.Methods["AddSslCertificate"]
$methodInstance = $method.CreateInstance()
$methodInstance.Input.SetAttributeValue("certificateHash", $certThumbprint)
$methodInstance.Input.SetAttributeValue("certificateStoreName", $certStore)
$methodInstance.Execute()

Using ES6 modules (initially proposed by @d13) works well for me. It doesn't mimic private properties perfectly, but at least you can be confident that properties that should be private won't leak outside of your class. Here's an example:

something.js

let _message = null;
const _greet = name => {
  console.log('Hello ' + name);
};

export default class Something {
  constructor(message) {
    _message = message;
  }

  say() {
    console.log(_message);
    _greet('Bob');
  }
};

Then the consuming code can look like this:

import Something from './something.js';

const something = new Something('Sunny day!');
something.say();
something._message; // undefined
something._greet(); // exception

Update (Important):

As @DanyalAytekin outlined in the comments, these private properties are static, so therefore global in scope. They will work well when working with Singletons, but care must be taken for Transient objects. Extending the example above:

import Something from './something.js';
import Something2 from './something.js';

const a = new Something('a');
a.say(); // a

const b = new Something('b');
b.say(); // b

const c = new Something2('c');
c.say(); // c

a.say(); // c
b.say(); // c
c.say(); // c

Dockerfile comments start with '#', just like Python. Here is a good example (kstaken/dockerfile-examples):

I've found out that GPS does not need Internet, BUT of course if you need to download maps, you will need a data connection or wifi.

You even can use require of your JSON without specifying the extension .json. It will let you change the file extension to .js without any changes in your imports.

assuming we have ./myJsonFile.json in the same directory.

const data = require('./myJsonFile')

If in the future you'll change ./myJsonFile.json to ./myJsonFile.js nothing should be changed in the import.

The problem, as the error message suggests, is that you have constraints of type NSAutoresizingMaskLayoutConstraints that conflict with your explicit constraints, because new_view.translatesAutoresizingMaskIntoConstraints is set to true.

This is the default setting for views you create in code. You can turn it off like this:

var new_view:UIView! = UIView(frame: CGRectMake(0, 0, 100, 100))
new_view.translatesAutoresizingMaskIntoConstraints = false

Also, your width and height constraints are weird. If you want the view to have a constant width, this is the proper way:

new_view.addConstraint(NSLayoutConstraint(
    item:new_view, attribute:NSLayoutAttribute.Width,
    relatedBy:NSLayoutRelation.Equal,
    toItem:nil, attribute:NSLayoutAttribute.NotAnAttribute,
    multiplier:0, constant:100))

(Replace 100 by the width you want it to have.)

If your deployment target is iOS 9.0 or later, you can use this shorter code:

new_view.widthAnchor.constraintEqualToConstant(100).active = true

Anyway, for a layout like this (fixed size and centered in parent view), it would be simpler to use the autoresizing mask and let the system translate the mask into constraints:

var new_view:UIView! = UIView(frame: CGRectMake(0, 0, 100, 100))
new_view.backgroundColor = UIColor.redColor();
view.addSubview(new_view);

// This is the default setting but be explicit anyway...
new_view.translatesAutoresizingMaskIntoConstraints = true

new_view.autoresizingMask = [ .FlexibleTopMargin, .FlexibleBottomMargin,
    .FlexibleLeftMargin, .FlexibleRightMargin ]

new_view.center = CGPointMake(view.bounds.midX, view.bounds.midY)

Note that using autoresizing is perfectly legitimate even when you're also using autolayout. (UIKit still uses autoresizing in lots of places internally.) The problem is that it's difficult to apply additional constraints to a view that is using autoresizing.

@Column is not the appropriate annotation. You don't want to store a whole User or Question in a column. You want to create an association between the entities. Start by renaming Questions to Question, since an instance represents a single question, and not several ones. Then create the association:

@Entity
@Table(name = "UserAnswer")
public class UserAnswer {

The Hibernate documentation explains that. Read it. And also read the javadoc of the annotations.

You can use git rebase -i (against the branch you branched from) 'i' for interactive.

Replace the pick next to the commit comment you wish to change with r (or reword), save and exit and upon doing so you'll be able to make the edit.

git push once again and you're done!

Yes, the best practice is to check-in (YES, CHECK-IN)

I agree that it will cause a lot of noise or conflict when seeing the diff. But the benefits are:

1. guarantee exact same version of every package. This part is the most important when building in different environments at different times. You may use ^1.2.3 in your package.json, but how can u ensure each time npm install will pick up the same version in your dev machine and in the build server, especially those indirect dependency packages? Well, package-lock.json will ensure that. (With the help of npm ci which installs packages based on lock file)
2. it improves the installation process.
3. it helps with new audit feature npm audit fix (I think the audit feature is from npm version 6).

I have found answers to my confusions.

There is a very important difference between the root and the alias directives. This difference exists in the way the path specified in the root or the alias is processed.

In case of the root directive, full path is appended to the root including the location part, whereas in case of the alias directive, only the portion of the path NOT including the location part is appended to the alias.

To illustrate:

Let's say we have the config

location /static/ {
    root /var/www/app/static/;
    autoindex off;
}

In this case the final path that Nginx will derive will be

/var/www/app/static/static

This is going to return 404 since there is no static/ within static/

This is because the location part is appended to the path specified in the root. Hence, with root, the correct way is

location /static/ {
    root /var/www/app/;
    autoindex off;
}

On the other hand, with alias, the location part gets dropped. So for the config

location /static/ {
    alias /var/www/app/static/;
    autoindex off;           ?
}                            |
                             pay attention to this trailing slash

the final path will correctly be formed as

/var/www/app/static

The case of trailing slash for alias directive

There is no definitive guideline about whether a trailing slash is mandatory per Nginx documentation, but a common observation by people here and elsewhere seems to indicate that it is.

A few more places have discussed this, not conclusively though.

On Windows, you can use Mac on a virtual machine (this probably also works on Linux but I haven't tested). A virtual machine is basically a program that you run on your computer that allows you to run one OS in a window inside another one. Make sure you have at least 60GB free space on your hard drive. The virtual hard drive that you will download takes up 10GB initially but when you've installed all the necessary programs for developing iOS apps its size can easily increase to 50GB (I recommend leaving a few GBs margin just in case).

Here are some detailed steps for how install a Mac virtual machine on Windows:

1. Install VirtualBox.

2. You have to enable virtualization in the BIOS. To open the BIOS on Windows 10, you need to start by holding down the Shift key while pressing the Restart button in the start menu. Then you will get a blue screen with some options. Choose "Troubleshoot", then "Advanced options", then "UEFI Firmware Settings", then "Restart". Then your computer will restart and open the BIOS directly. On older versions of Windows, shut down the computer normally, hold the F2 key down, start your computer again and don't release F2 until you're in the BIOS. On some computers you may have to hold down another key than F2.

3. Now that you're in the BIOS, you need to enable virtualization. Which setting you're supposed to change depends on which computer you're using. This may vary even between two computers with the same version of Windows. On my computer, you need to set Intel Virtual Technology in the Configuration tab to Enabled. On other computers it may be in for example Security -> Virtualization or in Advanced -> CPU Setup. If you can't find any of these options, search Google for enable virtualization (the kind of computer you have). Don't change anything in the BIOS just like that at random because otherwise it could cause problems on your computer. When you've enabled virtualization, save the changes and exit the BIOS. This is usually done in the Exit tab.

4. Download this file (I have no association with the person who uploaded it, but I've used it myself so I'm sure there are no viruses). If the link gets broken, post a comment to let me know and I will try to upload the file somewhere else. The password to open the 7Z file is stackoverflow.com. This 7Z file contains a VMDK file which will act as the hard drive for the Mac virtual machine. Extract that VMDK file. If disk space is an issue for you, once you've extracted the VMDK file, you can delete the 7Z file and therefore save 7GB.

5. Open VirtualBox that you installed in step 1. In the toolbar, press the New button. Then choose a name for your virtual machine (the name is unimportant, I called it "Mac"). In "Type", select "Mac OS X" and in "Version" select "macOS 10.13 High Sierra (64 bit)" (the Mac version you will install on the virtual machine is actually Catalina, but VirtualBox doesn't have that option yet and it works just fine if VirtualBox thinks it's High Sierra).

   

   It's also a good idea (though not required) to move the VMDK file you extracted in step 4 to the folder listed under "Machine Folder" (in the screenshot above that would be C:\Users\myname\VirtualBox VMs).

6. Select the amount of memory that your virtual machine can use. Try to balance the amount because too little memory will result in the virtual machine having low performance and a too much memory will result making your host system (Windows) run out of memory which will cause the virtual machine and/or other programs that you're running on Windows to crash. On a computer with 4GB available memory, 2GB was a good amount. Don't worry if you select a bad amount, you will be able to change it whenever you want (except when the virtual machine is running).

7. In the Hard disk step, choose "Use an existing virtual hard disk file" and click on the little folder icon to the right of the drop list. That will open a new window. In that new window, click on the "Add" button on the top left, which will open a browse window. Select the VMDK file that you downloaded and extracted in step 4, then click "Choose".

   

   When you're done with this, click "Create".

8. Select the virtual machine in the list on the left of the window and click on the Settings button in the toolbar. In System -> Processor, select 2 CPUs; and in Network -> Attached to, select Bridged Adapter. If you realize later that you selected an amount of memory in step 6 that causes problems, you can change it in System -> Motherboard. When you're done changing the settings, click OK.

9. Open the command prompt (C:\Windows\System32\cmd.exe). Run the following commands in there, replacing "Your VM Name" with whatever you called your virtual machine in step 5 (for example "Mac") (keep the quotation marks):

   cd "C:\Program Files\Oracle\VirtualBox\"
   VBoxManage.exe modifyvm "Your VM Name" --cpuidset 00000001 000106e5 00100800 0098e3fd bfebfbff
   VBoxManage setextradata "Your VM Name" "VBoxInternal/Devices/efi/0/Config/DmiSystemProduct" "iMac11,3"
   VBoxManage setextradata "Your VM Name" "VBoxInternal/Devices/efi/0/Config/DmiSystemVersion" "1.0"
   VBoxManage setextradata "Your VM Name" "VBoxInternal/Devices/efi/0/Config/DmiBoardProduct" "Iloveapple"
   VBoxManage setextradata "Your VM Name" "VBoxInternal/Devices/smc/0/Config/DeviceKey" "ourhardworkbythesewordsguardedpleasedontsteal(c)AppleComputerInc"
   VBoxManage setextradata "Your VM Name" "VBoxInternal/Devices/smc/0/Config/GetKeyFromRealSMC" 1
   VBoxManage setextradata "Your VM Name" "VBoxInternal/Devices/efi/0/Config/DmiSystemSerial" C02L280HFMR7
   

10. Now everything is ready for you to use the virtual machine. In VirtualBox, click on the Start button and follow the installation instructions for Mac. Once you've installed Mac on the virtual machine, you can develop your iOS app just like if you had a real Mac.

Remark: If you want to save space on your hard disk, you can compress the VMDK file that you extracted in step 4 and used in step 7. To do this, right click on it, select Properties, click on the Advanced... button on the bottom right, and check the checkbox "Compress contents to save disk space". This will make this very large file take less disk space without making anything work less well. I did it and it reduced the disk size of the VMDK file from 50GB to 40GB without losing any data.

Check the parse_string function http://php.net/manual/en/function.parse-str.php

It will return all the variables from a query string, including arrays.

Example from php.net:

<?php
$str = "first=value&arr[]=foo+bar&arr[]=baz";
parse_str($str);
echo $first;  // value
echo $arr[0]; // foo bar
echo $arr[1]; // baz

parse_str($str, $output);
echo $output['first'];  // value
echo $output['arr'][0]; // foo bar
echo $output['arr'][1]; // baz

?>

using memcpy

char *str1="hello";
char *str2=" world";
char *str3;

str3=(char *) malloc (11 *sizeof(char));
memcpy(str3,str1,5);
memcpy(str3+strlen(str1),str2,6);

printf("%s + %s = %s",str1,str2,str3);
free(str3);

If you are using Underscore.js or Lodash, there is a function 'omit' that will do it.
http://underscorejs.org/#omit

var thisIsObject= {
    'Cow' : 'Moo',
    'Cat' : 'Meow',
    'Dog' : 'Bark'
};
_.omit(thisIsObject,'Cow'); //It will return a new object

=> {'Cat' : 'Meow', 'Dog' : 'Bark'}  //result

If you want to modify the current object, assign the returning object to the current object.

thisIsObject = _.omit(thisIsObject,'Cow');

With pure JavaScript, use:

delete thisIsObject['Cow'];

Another option with pure JavaScript.

thisIsObject.cow = undefined;

thisIsObject = JSON.parse(JSON.stringify(thisIsObject ));

Use the replace function in js:

var emailAdd = $(this).text().replace(/ /g,'');

That will remove all the spaces

If you want to remove the leading and trailing whitespace only, use the jQuery $.trim method :

var emailAdd = $.trim($(this).text());

Ah man there are so many weird answers...

const execute = (fn) => fn()
const arrayOfFunctions = [fn1, fn2, fn3]

const results = arrayOfFunctions.map(execute)

or if you want to sequentially feed each functions result to the next:
compose(fn3, fn2, fn1)

compose is not supported by default, but there are libraries like ramda, lodash, or even redux which provide this tool

We can check with 2 built in functions

os.path.isdir("directory")

It will give boolean true the specified directory is available.

os.path.exists("directoryorfile")

It will give boolead true if specified directory or file is available.

To check whether the path is directory;

os.path.isdir("directorypath")

will give boolean true if the path is directory

If anyone is getting this error after a Phpmyadmin export, using the custom options and adding the "drop tables" statements cleared this right up.

Just add AsEnumerable() andToList() , so it looks like this

db.Favorites
    .Where(x => x.userId == userId)
    .Join(db.Person, x => x.personId, y => y.personId, (x, y).ToList().AsEnumerable()

ToList().AsEnumerable()

$('.btnMedio').click(function(event) {
    // Preventing default action of the event
    event.preventDefault();
    // Getting the height of the document
    var n = $(document).height();
    $('html, body').animate({ scrollTop: n }, 50);
//                                       |    |
//                                       |    --- duration (milliseconds) 
//                                       ---- distance from the top
});

Just want to add this. I had this problem today. Adjusted the settings in my project, rebuilt, and same problem. I had (incorrectly) assumed that changing the settings in my project (Eclipse) would cause the projects on which my project depends to be recompiled also. Adjusting the settings to all of the projects up the dependency tree solved the problem.

4.19.4 The instanceof operator

The instanceof operator requires the left operand to be of type Any, an object type, or a type parameter type, and the right operand to be of type Any or a subtype of the 'Function' interface type. The result is always of the Boolean primitive type.

So you could use

mySprite instanceof Sprite;

Note that this operator is also in ActionScript but it shouldn't be used there anymore:

The is operator, which is new for ActionScript 3.0, allows you to test whether a variable or expression is a member of a given data type. In previous versions of ActionScript, the instanceof operator provided this functionality, but in ActionScript 3.0 the instanceof operator should not be used to test for data type membership. The is operator should be used instead of the instanceof operator for manual type checking, because the expression x instanceof y merely checks the prototype chain of x for the existence of y (and in ActionScript 3.0, the prototype chain does not provide a complete picture of the inheritance hierarchy).

TypeScript's instanceof shares the same problems. As it is a language which is still in its development I recommend you to state a proposal of such facility.

See also:

• MDN: instanceof

with LoDash you could simply do this:

_.transform(this.attributes, function (result, item) {
  item.specified && (result[item.name] = item.value);
}, {});

I have given the comparison of all three discussed above.

Using values

%timeit df['value'] = df['a'].values % df['c'].values

139 µs ± 1.91 µs per loop (mean ± std. dev. of 7 runs, 10000 loops each)

Without values

%timeit df['value'] = df['a']%df['c'] 

216 µs ± 1.86 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)

Apply function

%timeit df['Value'] = df.apply(lambda row: row['a']%row['c'], axis=1)

474 µs ± 5.07 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)

@Sparr is right, but I guess you expected byte array like byte[] in C#. It's the same solution as Sparr did but instead of HEX you expected int presentation (range from 0 to 255) of each char. You can do as follows:

$byte_array = unpack('C*', 'The quick fox jumped over the lazy brown dog');
var_dump($byte_array);  // $byte_array should be int[] which can be converted
                        // to byte[] in C# since values are range of 0 - 255

By using var_dump you can see that elements are int (not string).

   array(44) {  [1]=>  int(84)  [2]=>  int(104) [3]=>  int(101) [4]=>  int(32)
[5]=> int(113)  [6]=>  int(117) [7]=>  int(105) [8]=>  int(99)  [9]=>  int(107)
[10]=> int(32)  [11]=> int(102) [12]=> int(111) [13]=> int(120) [14]=> int(32)
[15]=> int(106) [16]=> int(117) [17]=> int(109) [18]=> int(112) [19]=> int(101)
[20]=> int(100) [21]=> int(32)  [22]=> int(111) [23]=> int(118) [24]=> int(101)
[25]=> int(114) [26]=> int(32)  [27]=> int(116) [28]=> int(104) [29]=> int(101)
[30]=> int(32)  [31]=> int(108) [32]=> int(97)  [33]=> int(122) [34]=> int(121)
[35]=> int(32)  [36]=> int(98)  [37]=> int(114) [38]=> int(111) [39]=> int(119)
[40]=> int(110) [41]=> int(32)  [42]=> int(100) [43]=> int(111) [44]=> int(103) }

Be careful: the output array is of 1-based index (as it was pointed out in the comment)

If you use numpy, this is easy:

slice = arr[:2,:2]

or if you want the 0's,

slice = arr[0:2,0:2]

You'll get the same result.

*note that slice is actually the name of a builtin-type. Generally, I would advise giving your object a different "name".

Another way, if you're working with lists of lists*:

slice = [arr[i][0:2] for i in range(0,2)]

(Note that the 0's here are unnecessary: [arr[i][:2] for i in range(2)] would also work.).

What I did here is that I take each desired row 1 at a time (arr[i]). I then slice the columns I want out of that row and add it to the list that I'm building.

If you naively try: arr[0:2] You get the first 2 rows which if you then slice again arr[0:2][0:2], you're just slicing the first two rows over again.

*This actually works for numpy arrays too, but it will be slow compared to the "native" solution I posted above.

html {height: 101%;}

I use this cross browsers solution (note: I always use DOCTYPE declaration in 1st line, I don't know if it works in quirksmode, never tested it).

This will always show an ACTIVE vertical scroll bar in every page, vertical scrollbar will be scrollable only of few pixels.

When page contents is shorter than browser's visible area (view port) you will still see the vertical scrollbar active, and it will be scrollable only of few pixels.

In case you are obsessed with CSS validation (I'm obesessed only with HTML validation) by using this solution your CSS code would also validate for W3C because you are not using non standard CSS attributes like -moz-scrollbars-vertical

Varchar is for small data like email addresses, while Text is for much bigger data like news articles, Blob for binary data such as images.

The performance of Varchar is more powerful because it runs completely from memory, but this will not be the case if data is too big like varchar(4000) for example.

Text, on the other hand, does not stick to memory and is affected by disk performance, but you can avoid that by separating text data in a separate table and apply a left join query to retrieve text data.

Blob is much slower so use it only if you don't have much data like 10000 images which will cost 10000 records.

Follow these tips for maximum speed and performance:

1. Use varchar for name, titles, emails

2. Use Text for large data

3. Separate text in different tables

4. Use Left Join queries on an ID such as a phone number

5. If you are going to use Blob apply the same tips as in Text

This will make queries cost milliseconds on tables with data >10 M and size up to 10GB guaranteed.

The issue with CSS Styling is that it's not changing the data, and if you don't want to have a JS function then try...

<input onkeyup="this.value = this.value.toUpperCase()" />

on it's own you'll see the field capitalise on keyup, so it might be desirable to combine this with the style='text-transform:uppercase' others have suggested.

I have tried something like this and it works as expected:

f = open("c:\\log.log", 'r+b')
f.write("\x5F\x9D\x3E")
f.read(100)
f.close()

Where:

f.read(size) - To read a file’s contents, call f.read(size), which reads some quantity of data and returns it as a string.

And:

f.write(string) writes the contents of string to the file, returning None.

Also if you open Python tutorial about reading and writing files you will find that:

'r+' opens the file for both reading and writing.

On Windows, 'b' appended to the mode opens the file in binary mode, so there are also modes like 'rb', 'wb', and 'r+b'.

You can use asdf to install and switch between multiple java versions. It has plugins for other languages as well. You can install asdf with Homebrew

brew install asdf

When asdf is configured, install java plugin

asdf plugin-add java

Pick a version to install

asdf list-all java

For example to install and configure adoptopenjdk8

asdf install java adoptopenjdk-8.0.272+10
asdf global java adoptopenjdk-8.0.272+10

And finally if needed, configure JAVA_HOME for your shell. Just add to your shell init script such as ~/.zshrc in case of zsh:

. ~/.asdf/plugins/java/set-java-home.zsh

function hasSpaces(str) {
  if (str.indexOf(' ') !== -1) {
    return true
  } else {
    return false
  }
}

Addition to the accepted answer:

if you are going to use

 @Html.ActionLink("LinkName", "ActionName", "ControllerName", new { @id = idValue, @secondParam= = 2 },null)

this will create actionlink where you can't create new custom attribute or style for the link.

However, the 4th parameter in ActionLink extension will solve that problem. Use the 4th parameter for customization in your way.

 @Html.ActionLink("LinkName", "ActionName", "ControllerName", new { @id = idValue, @secondParam= = 2 }, new { @class = "btn btn-info", @target = "_blank" })

In oracle db there is a trick for casting int to float (I suppose, it should also work in mysql):

select myintfield + 0.0 as myfloatfield from mytable

While @Heximal's answer works, I don't personally recommend it.

This is because it uses implicit casting. Although you didn't type CAST, either the SUM() or the 0.0 need to be cast to be the same data-types, before the + can happen. In this case the order of precedence is in your favour, and you get a float on both sides, and a float as a result of the +. But SUM(aFloatField) + 0 does not yield an INT, because the 0 is being implicitly cast to a FLOAT.

I find that in most programming cases, it is much preferable to be explicit. Don't leave things to chance, confusion, or interpretation.

If you want to be explicit, I would use the following.

CAST(SUM(sl.parts) AS FLOAT) * cp.price
-- using MySQL CAST FLOAT  requires 8.0

You can try the following to see what happens...

CAST(SUM(sl.parts) AS NUMERIC(10,4)) * CAST(cp.price AS NUMERIC(10,4))

A solution without the use of calendar:

def add_month_year(date, years=0, months=0):
    year, month = date.year + years, date.month + months + 1
    dyear, month = divmod(month - 1, 12)
    rdate = datetime.date(year + dyear, month + 1, 1) - datetime.timedelta(1)
    return rdate.replace(day = min(rdate.day, date.day))

The following will transform your existing entries.

TransformedMap.decorateTransform(params, keyTransformer, valueTransformer)

Where as

MapUtils.transformedMap(java.util.Map map, keyTransformer, valueTransformer)

only transforms new entries into your map

If you are using the newest version of Android Studio, you can let it assist you in this.

Note: I have tested this in Android Studio 3.0 only.

The procedure is as follows:

1. In the project view (this comes along with captures and structure on the left side of screen), select Project instead of Android.
   The name of your project will be the top of the tree (alongside external libraries).
   Select your project then go to Refactor -> Copy....
   Android Studio will ask you the new name and where you want to copy the project. Provide the same.

2. After the copying is done, open your new project in Android Studio.
   Packages will still be under the old project name.
   That is the Java classes packages, application ID and everything else that was generated using the old package name.
   We need to change that.
   In the project view, select Android.
   Open the java sub-directory and select the main package.
   Then right click on it and go to Refactor then Rename.
   Android Studio will give you a warning saying that multiple directories correspond to the package you are about to refactor.
   Click on Rename package and not Rename directory.
   After this step, your project is now completely under the new name.

3. Open up the res/values/strings.xml file, and change the name of the project.
4. Don't forget to change your application ID in the "Gradle Build Module: app".
5. A last step is to clean and rebuild the project otherwise when trying to run your project Android Studio will tell you it can't install the APK (if you ran the previous project).
   So Build -> Clean project then Build -> Rebuild project.
   Now you can run your new cloned project.

Finally found the simplest way:

<button (click)="toggle($event)" class="someclass" id="btn1"></button>
<button (click)="toggle($event)" class="someclass" id="btn2"></button>

toggle(event) {
   console.log(event.target.id); 
}

Get to your Gmail account's security settings and set permissions for "Less secure apps" to Enabled. Worked for me.

You should target the smallest, not the largest, supported pixel resolution by the devices your app can run on.

Say if there's an actual Mac computer that can run OS X 10.9 and has a native screen resolution of only 1280x720 then that's the resolution you should focus on. Any higher and your game won't correctly run on this device and you could as well remove that device from your supported devices list.

You can rely on upscaling to match larger screen sizes, but you can't rely on downscaling to preserve possibly important image details such as text or smaller game objects.

The next most important step is to pick a fitting aspect ratio, be it 4:3 or 16:9 or 16:10, that ideally is the native aspect ratio on most of the supported devices. Make sure your game only scales to fit on devices with a different aspect ratio.

You could scale to fill but then you must ensure that on all devices the cropped areas will not negatively impact gameplay or the use of the app in general (ie text or buttons outside the visible screen area). This will be harder to test as you'd actually have to have one of those devices or create a custom build that crops the view accordingly.

Alternatively you can design multiple versions of your game for specific and very common screen resolutions to provide the best game experience from 13" through 27" displays. Optimized designs for iMac (desktop) and a Macbook (notebook) devices make the most sense, it'll be harder to justify making optimized versions for 13" and 15" plus 21" and 27" screens.

But of course this depends a lot on the game. For example a tile-based world game could simply provide a larger viewing area onto the world on larger screen resolutions rather than scaling the view up. Provided that this does not alter gameplay, like giving the player an unfair advantage (specifically in multiplayer).

You should provide @2x images for the Retina Macbook Pro and future Retina Macs.

In the particular situation outlined in the question,

typeof window.console === "undefined"

is identical to

window.console === undefined

I prefer the latter since it's shorter.

Please note that we look up for console only in global scope (which is a window object in all browsers). In this particular situation it's desirable. We don't want console defined elsewhere.

@BrianKelley in his great answer explains technical details. I've only added lacking conclusion and digested it into something easier to read.

I think the best practice is to have single primary constructor to which the overloaded constructors refer to by calling this() with the relevant parameter defaults. The reason for this is that it makes it much clearer what is the constructed state of the object is - really you can think of the primary constructor as the only real constructor, the others just delegate to it

One example of this might be JTable - the primary constructor takes a TableModel (plus column and selection models) and the other constructors call this primary constructor.

For subclasses where the superclass already has overloaded constructors, I would tend to assume that it is reasonable to treat any of the parent class's constructors as primary and think it is perfectly legitimate not to have a single primary constructor. For example,when extending Exception, I often provide 3 constructors, one taking just a String message, one taking a Throwable cause and the other taking both. Each of these constructors calls super directly.

public class XMLParser {
   public static void main(String[] args){
      try {
         DocumentBuilder dBuilder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
         Document doc = dBuilder.parse(new File("xml input"));
         NodeList nl=doc.getDocumentElement().getChildNodes();

         for(int k=0;k<nl.getLength();k++){
             printTags((Node)nl.item(k));
         }
      } catch (Exception e) {/*err handling*/}
   }

   public static void printTags(Node nodes){
       if(nodes.hasChildNodes()  || nodes.getNodeType()!=3){
           System.out.println(nodes.getNodeName()+" : "+nodes.getTextContent());
           NodeList nl=nodes.getChildNodes();
           for(int j=0;j<nl.getLength();j++)printTags(nl.item(j));
       }
   }
}

Recursively loop through and print out all the xml child tags in the document, in case you don't have to change the code to handle dynamic changes in xml, provided it's a well formed xml.

If you want to pass the type, than the equivalent in Java would be

java.lang.Class

If you want to use a weakly typed method, then you would simply use

java.lang.Object

and the corresponding operator

instanceof

e.g.

private void foo(Object o) {

  if(o instanceof String) {

  }

}//foo

However, in Java there are primitive types, which are not classes (i.e. int from your example), so you need to be careful.

The real question is what you actually want to achieve here, otherwise it is difficult to answer:

Or is there a better way?

void is an operator that is used to return a undefined value so the browser will not be able to load a new page.

Web browsers will try and take whatever is used as a URL and load it unless it is a JavaScript function that returns null. For example, if we click a link like this:

<a href="javascript: alert('Hello World')">Click Me</a>

then an alert message will show up without loading a new page, and that is because alert is a function that returns a null value. This means that when the browser attempts to load a new page it sees null and has nothing to load.

An important thing to note about the void operator is that it requires a value and cannot be used by itself. We should use it like this:

<a href="javascript: void(0)">I am a useless link</a>

I use this one:

LocationManager.requestLocationUpdates(String provider, long minTime, float minDistance, LocationListener listener)

For example, using a 1s interval:

locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,1000,0,this);

the time is in milliseconds, the distance is in meters.

This automatically calls:

public void onLocationChanged(Location location) {
    //Code here, location.getAccuracy(), location.getLongitude() etc...
}

I also had these included in the script but didnt actually use them:

public void onStatusChanged(String provider, int status, Bundle extras) {}
public void onProviderEnabled(String provider) {}
public void onProviderDisabled(String provider) {}

In short:

public class GPSClass implements LocationListener {

    public void onLocationChanged(Location location) {
        // Called when a new location is found by the network location provider.
        Log.i("Message: ","Location changed, " + location.getAccuracy() + " , " + location.getLatitude()+ "," + location.getLongitude());
    }

    public void onStatusChanged(String provider, int status, Bundle extras) {}
    public void onProviderEnabled(String provider) {}
    public void onProviderDisabled(String provider) {}

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
        locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,1000,0,this);
    }
}

There does exist a split function based on regular expressions. It's not listed in the tutorial, but it is listed on the language manual on the wiki:

split(string str, string pat)
   Split str around pat (pat is a regular expression) 

In your case, the delimiter "|" has a special meaning as a regular expression, so it should be referred to as "\\|".

vector<string> split(string str, string token){
    vector<string>result;
    while(str.size()){
        int index = str.find(token);
        if(index!=string::npos){
            result.push_back(str.substr(0,index));
            str = str.substr(index+token.size());
            if(str.size()==0)result.push_back(str);
        }else{
            result.push_back(str);
            str = "";
        }
    }
    return result;
}

split("1,2,3",",") ==> ["1","2","3"]

split("1,2,",",") ==> ["1","2",""]

split("1token2token3","token") ==> ["1","2","3"]

Your #container should be outside of the #header-wrap, then specify a fixed height for #header-wrap, after, specify margin-top for #container equal to the #header-wrap's height. Something like this:

#header-wrap {
    position: fixed;
    height: 200px;
    top: 0;
    width: 100%;
    z-index: 100;
}
#container{ 
    margin-top: 200px;
}

Hope this is what you need: http://jsfiddle.net/KTgrS/

Try this:

s = s.replaceAll("[,]$", "");

You'll need to use a different SimpleDateFormat object for each different pattern. That said, you don't need that many different ones, thanks to this:

Number: For formatting, the number of pattern letters is the minimum number of digits, and shorter numbers are zero-padded to this amount. For parsing, the number of pattern letters is ignored unless it's needed to separate two adjacent fields.

So, you'll need these formats:

• "M/y" (that covers 9/09, 9/2009, and 09/2009)
• "M/d/y" (that covers 9/1/2009)
• "M-d-y" (that covers 9-1-2009)

So, my advice would be to write a method that works something like this (untested):

// ...
List<String> formatStrings = Arrays.asList("M/y", "M/d/y", "M-d-y");
// ...

Date tryParse(String dateString)
{
    for (String formatString : formatStrings)
    {
        try
        {
            return new SimpleDateFormat(formatString).parse(dateString);
        }
        catch (ParseException e) {}
    }

    return null;
}

The simplest way using ClosedXml.

Imports ClosedXML.Excel

var dataList = new List<string>() { "a", "b", "c" };
var workbook = new XLWorkbook();     //creates the workbook
var wsDetailedData = workbook.AddWorksheet("data"); //creates the worksheet with sheetname 'data'
wsDetailedData.Cell(1, 1).InsertTable(dataList); //inserts the data to cell A1 including default column name
workbook.SaveAs(@"C:\data.xlsx"); //saves the workbook

For more info, you can also check wiki of ClosedXml. https://github.com/closedxml/closedxml/wiki

This will explain better.

EntityManager em = new JPAUtil().getEntityManager();
Session session = em.unwrap(Session.class);
Criteria c = session.createCriteria(Name.class);

Add the function ob_end_clean(); before call the Output function. It worked for me within a custom Wordpress function!

ob_end_clean();
$pdf->Output($pdf_name, 'I');

IE8's HTML5 support is limited, but Internet Explorer 9 has just been released and has strong support for the new emerging HTML5 technologies.

There are two 'must have' plugins for this:

1. sensible - Ctrl-l for nohlsearch and redraw screen.
2. unimpared - [oh, ]oh and coh to control hlsearch.

Even though it's convenient to use, it seems like the convert-to-hash solution costs quite a lot of performance, which was an issue for me.

#!/usr/bin/perl
use Benchmark;
my @list;
for (1..10_000) {
    push @list, $_;
}

timethese(10000, {
  'grep'    => sub {
            if ( grep(/^5000$/o, @list) ) {
                # code
            }
        },
  'hash'    => sub {
            my %params = map { $_ => 1 } @list;
            if ( exists($params{5000}) ) {
                # code
            }
        },
});

Output of benchmark test:

Benchmark: timing 10000 iterations of grep, hash...
          grep:  8 wallclock secs ( 7.95 usr +  0.00 sys =  7.95 CPU) @ 1257.86/s (n=10000)
          hash: 50 wallclock secs (49.68 usr +  0.01 sys = 49.69 CPU) @ 201.25/s (n=10000)

Simple Way To Achieve

I know it's an old question You can also do something like

SELECT * FROM Table WHERE id=1 ORDER BY signin DESC

In above, query the first record will be the most recent record.

For only one record you can use something like

SELECT top(1) * FROM Table WHERE id=1 ORDER BY signin DESC

Above query will only return one latest record.

Cheers!

Try this one out

public void getObjectList(){
        System.out.println("Listing objects");
        ObjectListing objectListing = s3.listObjects(new ListObjectsRequest()
                .withBucketName(bucketName)
                .withPrefix("ads"));
        for (S3ObjectSummary objectSummary : objectListing.getObjectSummaries()) {
            System.out.println(" - " + objectSummary.getKey() + "  " +
                               "(size = " + objectSummary.getSize() + ")");
        }
    }

You can all the objects within the bucket with specific prefix.

you can do something like adding a class to add border radius

HTML:

<a href="#" class="btn btn-default btn-circle"><i class="fa fa-user"></i></a>

CSS:

.btn-circle {
  width: 30px;
  height: 30px;
  text-align: center;
  padding: 6px 0;
  font-size: 12px;
  line-height: 1.42;
  border-radius: 15px;
}

in case you wanted to change dimension you need to change the font size or padding accordingly

Yes this is the way:

Right click on your program, select run -> run configuration then on vm argument

-Denv=EnvironmentName -Dcucumber.options="--tags @ifThereisAnyTag"

Then you can apply and close.

You can refer to https://curl.haxx.se/docs/http-cookies.html for a complete tutorial of how to work with cookies. You can use

curl -c /path/to/cookiefile http://yourhost/

to write to a cookie file and start engine and to use cookie you can use

curl -b /path/to/cookiefile  http://yourhost/

to read cookies from and start the cookie engine, or if it isn't a file it will pass on the given string.

I addition to the accepted answer, the error can also occur when the destination folder is read-only (Common when using TFS)

Write-Back is a more complex one and requires a complicated Cache Coherence Protocol(MOESI) but it is worth it as it makes the system fast and efficient.

The only benefit of Write-Through is that it makes the implementation extremely simple and no complicated cache coherency protocol is required.

I was using pgAdmin to create my tables and while I was not using reserved words, the generated table had a quote in the name and a couple of columns had quotes in them. Here is an example of the generated SQL.

CREATE TABLE public."Test"
(
    id serial NOT NULL,
    data text NOT NULL,
    updater character varying(50) NOT NULL,
    "updateDt" time with time zone NOT NULL,
    CONSTRAINT test_pk PRIMARY KEY (id)
)

TABLESPACE pg_default;

ALTER TABLE public."Test"
    OWNER to svc_newnews_app;

All of these quotes were inserted at "random". I just needed to drop and re-create the table again without the quotes.

Tested on pgAdmin 4.26

I hesitate to post this answer, it is actually technically possible but it doesn't work that well in practice. The version numbers of the CLR and the core framework assemblies were not changed in 4.5. You still target v4.0.30319 of the CLR and the framework assembly version numbers are still 4.0.0.0. The only thing that's distinctive about the assembly manifest when you look at it with a disassembler like ildasm.exe is the presence of a [TargetFramework] attribute that says that 4.5 is needed, that would have to be altered. Not actually that easy, it is emitted by the compiler.

The biggest difference is not that visible, Microsoft made a long-overdue change in the executable header of the assemblies. Which specifies what version of Windows the executable is compatible with. XP belongs to a previous generation of Windows, started with Windows 2000. Their major version number is 5. Vista was the start of the current generation, major version number 6.

.NET compilers have always specified the minimum version number to be 4.00, the version of Windows NT and Windows 9x. You can see this by running dumpbin.exe /headers on the assembly. Sample output looks like this:

OPTIONAL HEADER VALUES
             10B magic # (PE32)
            ...
            4.00 operating system version
            0.00 image version
            4.00 subsystem version              // <=== here!!
               0 Win32 version
            ...

What's new in .NET 4.5 is that the compilers change that subsystem version to 6.00. A change that was over-due in large part because Windows pays attention to that number, beyond just checking if it is small enough. It also turns on appcompat features since it assumes that the program was written to work on old versions of Windows. These features cause trouble, particularly the way Windows lies about the size of a window in Aero is troublesome. It stops lying about the fat borders of an Aero window when it can see that the program was designed to run on a Windows version that has Aero.

You can alter that version number and set it back to 4.00 by running Editbin.exe on your assemblies with the /subsystem option. This answer shows a sample postbuild event.

That's however about where the good news ends, a significant problem is that .NET 4.5 isn't very compatible with .NET 4.0. By far the biggest hang-up is that classes were moved from one assembly to another. Most notably, that happened for the [Extension] attribute. Previously in System.Core.dll, it got moved to Mscorlib.dll in .NET 4.5. That's a kaboom on XP if you declare your own extension methods, your program says to look in Mscorlib for the attribute, enabled by a [TypeForwardedTo] attribute in the .NET 4.5 version of the System.Core reference assembly. But it isn't there when you run your program on .NET 4.0

And of course there's nothing that helps you stop using classes and methods that are only available on .NET 4.5. When you do, your program will fail with a TypeLoadException or MissingMethodException when run on 4.0

Just target 4.0 and all of these problems disappear. Or break that logjam and stop supporting XP, a business decision that programmers cannot often make but can certainly encourage by pointing out the hassles that it is causing. There is of course a non-zero cost to having to support ancient operating systems, just the testing effort is substantial. A cost that isn't often recognized by management, Windows compatibility is legendary, unless it is pointed out to them. Forward that cost to the client and they tend to make the right decision a lot quicker :) But we can't help you with that.

document.ontouchmove = function(e){ 
    e.preventDefault(); 
}

is actually the best choice i found out it allows you to still be able to tap on input fields as well as drag things using jQuery UI draggable but it stops the page from scrolling.

It's a table-valued function, but you're using it as a scalar function.

Try:

where Emp_Id IN (SELECT i.items FROM dbo.Splitfn(@Id,',') AS i)

But... also consider changing your function into an inline TVF, as it'll perform better.

Wrote this handy function and put in my bash scripts or ~/.bash_aliases. Tested sync'ing locally on Linux with bash and awk installed. It works

selrsync(){
# selective rsync to sync only certain filetypes;
# based on: https://stackoverflow.com/a/11111793/588867
# Example: selrsync 'tsv,csv' ./source ./target --dry-run
types="$1"; shift; #accepts comma separated list of types. Must be the first argument.
includes=$(echo $types| awk  -F',' \
    'BEGIN{OFS=" ";}
    {
    for (i = 1; i <= NF; i++ ) { if (length($i) > 0) $i="--include=*."$i; } print
    }')
restargs="$@"

echo Command: rsync -avz --prune-empty-dirs --include="*/" $includes --exclude="*" "$restargs"
eval rsync -avz --prune-empty-dirs --include="*/" "$includes" --exclude="*" $restargs
}

Avantages:

short handy and extensible when one wants to add more arguments (i.e. --dry-run).

Example:

selrsync 'tsv,csv' ./source ./target --dry-run

It's possible to have HTML form elements disabled -- wouldn't that do? Your users would see it in one of three states, i.e. checked, unchecked, and disabled, which would be greyed out and not clickable. To me, that seems similar to "null" or "not applicable" or whatever you're looking for in that third state.

If the main intent is to check whether the supplied value is not found in a list, maybe you can use the extended regular expression matching built in BASH via the "equal tilde" operator (see also this answer):

if ! [[ "$cms" =~ ^(wordpress|meganto|typo3)$ ]]; then get_cms ; fi

Have a nice day

Anomies answer is good, but I felt insecure about this so I decided to add a couple of screenshots.

Step 0: git log

See where you are with git log. Most important, find the commit hash of the first commit you don't want to squash. So only the :

Step 1: git rebase

Execute git rebase -i [your hash], in my case:

$ git rebase -i 2d23ea524936e612fae1ac63c95b705db44d937d

Step 2: pick / squash what you want

In my case, I want to squash everything on the commit that was first in time. The ordering is from first to last, so exactly the other way as in git log. In my case, I want:

Step 3: Adjust message(s)

If you have picked only one commit and squashed the rest, you can adjust one commit message:

That's it. Once you save this (:wq), you're done. Have a look at it with git log.

It looks like you might not have defined a start script in your package.json file or your project does not contain a server.js file.

If there is a server.js file in the root of your package, then npm will default the start command to node server.js.

https://docs.npmjs.com/misc/scripts#default-values

You could either change the name of your application script to server.js or add the following to your package.json

"scripts": {
    "start": "node your-script.js"
}

Or ... you could just run node your-script.js directly
