You can use @Qualifier along with @Autowired. In fact spring will ask you explicitly select the bean if ambiguous bean type are found, in which case you should provide the qualifier

For Example in following case it is necessary provide a qualifier

@Component
@Qualifier("staff") 
public Staff implements Person {}

@Component
@Qualifier("employee") 
public Manager implements Person {}


@Component
public Payroll {

    private Person person;

    @Autowired
    public Payroll(@Qualifier("employee") Person person){
          this.person = person;
    }

}

EDIT:

In Lombok 1.18.4 it is finally possible to avoid the boilerplate on constructor injection when you have @Qualifier, so now it is possible to do the following:

@Component
@Qualifier("staff") 
public Staff implements Person {}

@Component
@Qualifier("employee") 
public Manager implements Person {}


@Component
@RequiredArgsConstructor
public Payroll {
   @Qualifier("employee") private final Person person;
}

provided you are using the new lombok.config rule copyableAnnotations (by placing the following in lombok.config in the root of your project):

# Copy the Qualifier annotation from the instance variables to the constructor
# see https://github.com/rzwitserloot/lombok/issues/745
lombok.copyableAnnotations += org.springframework.beans.factory.annotation.Qualifier

This was recently introduced in latest lombok 1.18.4.

• The blog post where the issue is discussed in detail
• The original issue on github
• And a small github project to see it in action

NOTE

If you are using field or setter injection then you have to place the @Autowired and @Qualifier on top of the field or setter function like below(any one of them will work)

public Payroll {
   @Autowired @Qualifier("employee") private final Person person;
}

or

public Payroll {
   private final Person person;
   @Autowired
   @Qualifier("employee")
   public void setPerson(Person person) {
     this.person = person;
   } 
}

If you are using constructor injection then the annotations should be placed on constructor, else the code would not work. Use it like below -

public Payroll {

    private Person person;

    @Autowired
    public Payroll(@Qualifier("employee") Person person){
          this.person = person;
    }

}

You can use JavaScript (don't need jQuery)

document.querySelectorAll('#selected li').length;

• There is no limit on objects per bucket.
• There is a limit of 100 buckets per account (you need to request amazon if you need more).
• There is no performance drop even if you store millions of objects in a single bucket.

From docs,

There is no limit to the number of objects that can be stored in a bucket and no difference in performance whether you use many buckets or just a few. You can store all of your objects in a single bucket, or you can organize them across several buckets.

Make sure you’re pushing the right branch. I wasn’t on master and kept wondering why it was complaining :P

You'll first need to separate your numpy array into two separate arrays containing x and y values.

x = [1, 2, 3, 9]
y = [1, 4, 1, 3]

curve_fit also requires a function that provides the type of fit you would like. For instance, a linear fit would use a function like

def func(x, a, b):
    return a*x + b

scipy.optimize.curve_fit(func, x, y) will return a numpy array containing two arrays: the first will contain values for a and b that best fit your data, and the second will be the covariance of the optimal fit parameters.

Here's an example for a linear fit with the data you provided.

import numpy as np
from scipy.optimize import curve_fit

x = np.array([1, 2, 3, 9])
y = np.array([1, 4, 1, 3])

def fit_func(x, a, b):
    return a*x + b

params = curve_fit(fit_func, x, y)

[a, b] = params[0]

This code will return a = 0.135483870968 and b = 1.74193548387

Here's a plot with your points and the linear fit... which is clearly a bad one, but you can change the fitting function to obtain whatever type of fit you would like.

It's faster to avoid using regular expressions, if you're just trying to find the first substring match within an array of string values. You can add your own array searching function:

Code:

Array.prototype.findFirstSubstring = function(s) {
            for(var i = 0; i < this.length;i++)
            {
                if(this[i].indexOf(s) !== -1)
                    return i;
            }
            return -1;
        };

Usage:

i.findFirstSubstring('height');

Returns:

-1 if not found or the array index of the first substring occurrence if it is found (in your case would be 2)

How to generate a random point within a circle of radius R:

r = R * sqrt(random())
theta = random() * 2 * PI

(Assuming random() gives a value between 0 and 1 uniformly)

If you want to convert this to Cartesian coordinates, you can do

x = centerX + r * cos(theta)
y = centerY + r * sin(theta)

Why sqrt(random())?

Let's look at the math that leads up to sqrt(random()). Assume for simplicity that we're working with the unit circle, i.e. R = 1.

The average distance between points should be the same regardless of how far from the center we look. This means for example, that looking on the perimeter of a circle with circumference 2 we should find twice as many points as the number of points on the perimeter of a circle with circumference 1.

Since the circumference of a circle (2πr) grows linearly with r, it follows that the number of random points should grow linearly with r. In other words, the desired probability density function (PDF) grows linearly. Since a PDF should have an area equal to 1 and the maximum radius is 1, we have

So we know how the desired density of our random values should look like. Now: How do we generate such a random value when all we have is a uniform random value between 0 and 1?

We use a trick called inverse transform sampling

1. From the PDF, create the cumulative distribution function (CDF)
2. Mirror this along y = x
3. Apply the resulting function to a uniform value between 0 and 1.

Sounds complicated? Let me insert a blockquote with a little side track that conveys the intuition:

Suppose we want to generate a random point with the following distribution:

                

That is

• 1/5 of the points uniformly between 1 and 2, and
• 4/5 of the points uniformly between 2 and 3.

The CDF is, as the name suggests, the cumulative version of the PDF. Intuitively: While PDF(x) describes the number of random values at x, CDF(x) describes the number of random values less than x.

In this case the CDF would look like:

                

To see how this is useful, imagine that we shoot bullets from left to right at uniformly distributed heights. As the bullets hit the line, they drop down to the ground:

                

See how the density of the bullets on the ground correspond to our desired distribution! We're almost there!

The problem is that for this function, the y axis is the output and the x axis is the input. We can only "shoot bullets from the ground straight up"! We need the inverse function!

This is why we mirror the whole thing; x becomes y and y becomes x:

                

We call this CDF^-1. To get values according to the desired distribution, we use CDF^-1(random()).

…so, back to generating random radius values where our PDF equals 2x.

Step 1: Create the CDF:

Since we're working with reals, the CDF is expressed as the integral of the PDF.

CDF(x) = ? 2x = x²

Step 2: Mirror the CDF along y = x:

Mathematically this boils down to swapping x and y and solving for y:

CDF:     y = x²
Swap:   x = y²
Solve:   y = √x
CDF^-1:  y = √x

Step 3: Apply the resulting function to a uniform value between 0 and 1

CDF^-1(random()) = √random()

Which is what we set out to derive :-)

You will have to open the file in one way or another if you want to access the data within it. Obviously, one way is to open it in your Excel application instance, e.g.:-

(untested code)

Dim wbk As Workbook
Set wbk = Workbooks.Open("C:\myworkbook.xls")

' now you can manipulate the data in the workbook anyway you want, e.g. '

Dim x As Variant
x = wbk.Worksheets("Sheet1").Range("A6").Value

Call wbk.Worksheets("Sheet2").Range("A1:G100").Copy
Call ThisWorbook.Worksheets("Target").Range("A1").PasteSpecial(xlPasteValues)
Application.CutCopyMode = False

' etc '

Call wbk.Close(False)

Another way to do it would be to use the Excel ADODB provider to open a connection to the file and then use SQL to select data from the sheet you want, but since you are anyway working from within Excel I don't believe there is any reason to do this rather than just open the workbook. Note that there are optional parameters for the Workbooks.Open() method to open the workbook as read-only, etc.

JavaScript validation is not secure as anybody can change what your script does in the browser. Using it for enhancing the visual experience is ok though.

var textBox = document.getElementById("myTextBox");
var textLength = textBox.value.length;
if(textLength > 5)
{
    //red
    textBox.style.backgroundColor = "#FF0000";
}
else
{
    //green
    textBox.style.backgroundColor = "#00FF00";
}

When i need to copy data from filtered table i use range.SpecialCells(xlCellTypeVisible).copy. Where the range is range of all data (without a filter).

Example:

Sub copy()
     'source worksheet
     dim ws as Worksheet
     set ws = Application.Worksheets("Data")' set you source worksheet here
     dim data_end_row_number as Integer
     data_end_row_number = ws.Range("B3").End(XlDown).Row.Number
    'enable filter
    ws.Range("B2:F2").AutoFilter Field:=2, Criteria1:="hockey", VisibleDropDown:=True
    ws.Range("B3:F" & data_end_row_number).SpecialCells(xlCellTypeVisible).Copy
    Application.Worksheets("Hoky").Range("B3").Paste
    'You have to add headers to Hoky worksheet
end sub

import pymongo
conn = pymongo.MongoClient()
db = conn.test #test is my database
col = db.spam #Here spam is my collection
array = list(col.find())

print array

There you go

In Web-"MVC" you can do whatever you please.

The original concept ⁽¹⁾ described the model as the business logic. It should represent the application state and enforce some data consistency. That approach is often described as "fat model".

Most PHP frameworks follow a more shallow approach, where the model is just a database interface. But at the very least these models should still validate the incoming data and relations.

Either way, you're not very far off if you separate the SQL stuff or database calls into another layer. This way you only need to concern yourself with the real data/behaviour, not with the actual storage API. (It's however unreasonable to overdo it. You'll e.g. never be able to replace a database backend with a filestorage if that wasn't designed ahead.)

It's ok to use mysql_insert_id(), but there is one specific note about using it, you must call it after executed INSERT query, means in the same script session. If you use it otherwise it wouldn't work correctly.

More convenient Swift 3 method:

UPDATE: The stroke-alignment attribute was on April 1st, 2015 moved to a completely new spec called SVG Strokes.

As of the SVG 2.0 Editor’s Draft of February 26th, 2015 (and possibly since February 13th), the stroke-alignment property is present with the values inner, center (default) and outer.

It seems to work the same way as the stroke-location property proposed by @Phrogz and the later stroke-position suggestion. This property has been planned since at least 2011, but apart from an annotation that said

SVG 2 shall include a way to specify stroke position

, it has never been detailed in the spec as it was deferred - until now, it seems.

No browser support this property, or, as far as I know, any of the new SVG 2 features, yet, but hopefully they will soon as the spec matures. This has been a property I personally have been urging to have, and I'm really happy that it's finally there in the spec.

There seems to be some issues as to how to the property should behave on open paths as well as loops. These issues will, most probably, prolong implementations across browsers. However, I will update this answer with new information as browsers begin to support this property.

This problem is generally caused by the website/intranet URL being placed in one of:

• Compatibility Mode List
• Internet Explorer Intranet Zone
  (with Display intranet sites in Compatibility View setting enabled)
• Enterprise Mode List

On corporate networks, these compatibility view settings are often controlled centrally via group policy. In your case, Enterprise Mode appears to be the culprit.

Unfortunately setting META X-UA-Compatible will not override this.

For End-Users

Sometimes the only way for end-users to override this is to press F12 and change the Document Mode under the Emulation Tab. However this setting is not permanent and may revert once Developer Tools is closed.

You can also try to exclude your site from the Intranet zone. But the list of domains which belong to the Intranet zone is usually also controlled by the group policy, so the chance of this working is slim.

To see the list of domains that belong to the Intranet zone, go to:

Tools -> Internet Options -> Security -> Sites -> Advanced

If the list contains your subdomain and is greyed out, then you will not be able to override compatibility view until your network admin allows it.

You really need to contact your network administrator to allow changing the compatibility view settings in the group policy.

For Network Admins

Loading the website with Developer Tools open (F12) will often report the reason that IE is switching to an older mode.

All 3 settings mentioned above are generally controlled via Group Policy, although can sometimes be overridden on user machines.

If Enterprise Mode is the issue (as appears to be the case for the original poster), the following two articles might be helpful:

• How to Enable and Use Internet Explorer 11’s Enterprise Mode [HowToGeek]
• Turn on Enterprise Mode and use a site list [TechNet]

You can use following lines of code to insert values into an already existing table. Here the table is db_name.table_name having two columns, and I am inserting 'All','done' as a row in the table.

insert into table db_name.table_name
select 'ALL','Done';

Hope this was helpful.

You have to match the settings for PHP-FPM and Nginx to communicate over sockets or TCP.

So go to /etc/php5/fpm/pool.d/www.conf and look for this line:

listen = /var/run/php5-fpm.sock

Then go to /etc/nginx/nginx.conf

Look for this:

upstream php {
    server unix:/var/run/php5-fpm.socket;
}

Match those values and you should be all set.

By default, when you click on a ListView item it doesn't change its state to "selected". So, when the event fires and you do:

myList.getSelectedItem();

The method doesn't have anything to return. What you have to do is to use the position and obtain the underlying object by doing:

myList.getItemAtPosition(position);

A simple Swift implementation, if you use outlets.

@IBOutlet weak var mapView: MKMapView! {
    didSet {
        let noLocation = CLLocationCoordinate2D()
        let viewRegion = MKCoordinateRegionMakeWithDistance(noLocation, 500, 500)
        self.mapView.setRegion(viewRegion, animated: false)
    }
}

Based on @Carnal's answer.

As Thomas Glick said, the latests versions of Fiddler2 works ok with all major browsers. But beware, there's a "Show only Internet Explorer traffic filter" in the filters sections, just disable that one and everything should work as expected, including other filters.

I also experienced np.array_split not working with Pandas DataFrame my solution was to only split the index of the DataFrame and then introduce a new column with the "group" label:

indexes = np.array_split(df.index,N, axis=0)
for i,index in enumerate(indexes):
   df.loc[index,'group'] = i

This makes grouby operations very convenient for instance calculation of mean value of each group:

df.groupby(by='group').mean()

Set in Parent view

justifyContent:center

and in child view alignSelf:center

Using the logging module you can automatically add the current thread identifier in each log entry. Just use one of these LogRecord mapping keys in your logger format string:

%(thread)d : Thread ID (if available).

%(threadName)s : Thread name (if available).

and set up your default handler with it:

logging.basicConfig(format="%(threadName)s:%(message)s")

Are you strong-naming your assemblies? In that case it is not a good idea to auto-increment your build number because with every new build number you will also have to update all your references.

Simply remove the line that rotates it one degree at a time and calls the script forever.

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

Then pass the desired value into the function... in this example 45 for 45 degrees.

$(function() {

    var $elie = $("#bkgimg");
    rotate(45);

        function rotate(degree) {
      // For webkit browsers: e.g. Chrome
           $elie.css({ WebkitTransform: 'rotate(' + degree + 'deg)'});
      // For Mozilla browser: e.g. Firefox
           $elie.css({ '-moz-transform': 'rotate(' + degree + 'deg)'});
        }

});

Change .css() to .animate() in order to animate the rotation with jQuery. We also need to add a duration for the animation, 5000 for 5 seconds. And updating your original function to remove some redundancy and support more browsers...

$(function() {

    var $elie = $("#bkgimg");
    rotate(45);

        function rotate(degree) {
            $elie.animate({
                        '-webkit-transform': 'rotate(' + degree + 'deg)',
                        '-moz-transform': 'rotate(' + degree + 'deg)',
                        '-ms-transform': 'rotate(' + degree + 'deg)',
                        '-o-transform': 'rotate(' + degree + 'deg)',
                        'transform': 'rotate(' + degree + 'deg)',
                        'zoom': 1
            }, 5000);
        }
});

EDIT: The standard jQuery CSS animation code above is not working because apparently, jQuery .animate() does not yet support the CSS3 transforms.

This jQuery plugin is supposed to animate the rotation:

http://plugins.jquery.com/project/QTransform

Set showInLegend to false.

series: [{
            showInLegend: false,
            name: 'Series',
            data: value                
        }]

ChDir "" was the solution for me. I use vba from WORD to launch a python3 script.

Try ps -ef. man ps will give you all the options.

 -A      Display information about other users' processes, including those without controlling terminals.

 -e      Identical to -A.

 -f      Display the uid, pid, parent pid, recent CPU usage, process start time, controlling tty, elapsed CPU usage, and the associated command.  If the -u option is also used, display
         the user name rather then the numeric uid.  When -o or -O is used to add to the display following -f, the command field is not truncated as severely as it is in other formats.

The following worked for me:

import sys, glob
sys.path.append('/home/marc/python/importtest/modus')
fl = glob.glob('modus/*.py')
modulist = []
adapters=[]
for i in range(len(fl)):
    fl[i] = fl[i].split('/')[1]
    fl[i] = fl[i][0:(len(fl[i])-3)]
    modulist.append(getattr(__import__(fl[i]),fl[i]))
    adapters.append(modulist[i]())

It loads modules from the folder 'modus'. The modules have a single class with the same name as the module name. E.g. the file modus/modu1.py contains:

class modu1():
    def __init__(self):
        self.x=1
        print self.x

The result is a list of dynamically loaded classes "adapters".

First of all, Applets are designed to be run from within the context of a browser (or applet viewer), they're not really designed to be added into other containers.

Technically, you can add a applet to a frame like any other component, but personally, I wouldn't. The applet is expecting a lot more information to be available to it in order to allow it to work fully.

Instead, I would move all of the "application" content to a separate component, like a JPanel for example and simply move this between the applet or frame as required...

ps- You can use f.setLocationRelativeTo(null) to center the window on the screen ;)

Updated

You need to go back to basics. Unless you absolutely must have one, avoid applets until you understand the basics of Swing, case in point...

Within the constructor of GalzyTable2 you are doing...

JApplet app = new JApplet(); add(app); app.init(); app.start(); 

...Why are you adding another applet to an applet??

Case in point...

Within the main method, you are trying to add the instance of JFrame to itself...

f.getContentPane().add(f, button2); 

Instead, create yourself a class that extends from something like JPanel, add your UI logical to this, using compound components if required.

Then, add this panel to whatever top level container you need.

Since ng-show is an angular attribute i think, we don't need to put the evaluation flower brackets ({{}})..

For attributes like class we need to encapsulate the variables with evaluation flower brackets ({{}}).

Another solution is:

protected void Application_Start()
{
    ...
    RequestValidator.Current = new MyRequestValidator();
}

public class MyRequestValidator: RequestValidator
{
    protected override bool IsValidRequestString(HttpContext context, string value, RequestValidationSource requestValidationSource, string collectionKey, out int validationFailureIndex)
    {
        bool result = base.IsValidRequestString(context, value, requestValidationSource, collectionKey, out validationFailureIndex);

        if (!result)
        {
            // Write your validation here
            if (requestValidationSource == RequestValidationSource.Form ||
                requestValidationSource == RequestValidationSource.QueryString)

                return true; // Suppress error message

NOTE: On the JVM, if all of the parameters of the primary constructor have default values, the compiler will generate an additional parameterless constructor which will use the default values. This makes it easier to use Kotlin with libraries such as Jackson or JPA that create class instances through parameterless constructors.

Doing password checks on client side is unsafe especially when the password is hard coded.

The safest way is password checking on server side, but even then the password should not be transmitted plain text.

Checking the password client side is possible in a "secure way":

• The password needs to be hashed
• The hashed password is used as part of a new url

Say "abc" is your password so your md5 would be "900150983cd24fb0d6963f7d28e17f72" (consider salting!). Now build a url containing the hash (like http://yourdomain.com/90015...f72.html).

You need to change div into p. Technically innerHTML means it is inside the <??? id=""></???> part.

Change:

<div id="hello"></div>

into

<p id="hello"></p>

Doing:

document.getElementById('hello').innerHTML = 'hi';

will turn

<div id="hello"></div> into this <div id="hello">hi</div>

which actually does not make sense.

You can also try to change:

document.getElementById('hello').innerHTML = 'hi';

into this

document.getElementById('hello').innerHTML='<p> hi </p> ';

to make it work.

A great way of handling this is with regular expressions.

string modifiedString = Regex.Replace(originalString, @"(\r\n)|\n|\r", "<br/>");

This will replace any of the 3 legal types of newline with the html tag.

Actually, there are four forms of this operator:

<>
!=
^=

and even

¬= -- worked on some obscure platforms in the dark ages

which are the same, but treated differently when a verbatim match is required (stored outlines or cached queries).

I faced the same issue and It is really strange that the same code works in few case whereas it failed in some random cases.

I got it fixed by just making sure the proper setter/getter (Making sure the case sensitivity)

I had the same problem.

I found these instructions that worked for me.

# Example of installing handcalcs directly from a notebook
!pip install --upgrade-strategy only-if-needed handcalcs

ref: https://docs.conda.io/projects/conda/en/latest/user-guide/tasks/manage-environments.html

Issues may arise when using pip and conda together. When combining conda and pip, it is best to use an isolated conda environment. Only after conda has been used to install as many packages as possible should pip be used to install any remaining software. If modifications are needed to the environment, it is best to create a new environment rather than running conda after pip. When appropriate, conda and pip requirements should be stored in text files.

We recommend that you:

Use pip only after conda

Install as many requirements as possible with conda then use pip.

Pip should be run with --upgrade-strategy only-if-needed (the default).

Do not use pip with the --user argument, avoid all users installs.

Suppose you want to insert a particular line of text (not an empty line):

@echo off
FOR /F %%C IN ('FIND /C /V "" ^<%origfile%') DO SET totallines=%%C
set /a totallines+=1

@echo off
<%origfile% (FOR /L %%i IN (1,1,%totallines%) DO (
  SETLOCAL EnableDelayedExpansion
  SET /p L=
  IF %%i==%insertat% ECHO(!TL!
  ECHO(!L!
  ENDLOCAL
)
) >%tempfile%

COPY /Y %tempfile% %origfile% >NUL

DEL %tempfile%

Why don't you put your results into a vector? That way you don't have to know the size before hand.

Python 3 renamed the unicode type to str, the old str type has been replaced by bytes.

if isinstance(unicode_or_str, str):
    text = unicode_or_str
    decoded = False
else:
    text = unicode_or_str.decode(encoding)
    decoded = True

You may want to read the Python 3 porting HOWTO for more such details. There is also Lennart Regebro's Porting to Python 3: An in-depth guide, free online.

Last but not least, you could just try to use the 2to3 tool to see how that translates the code for you.

I humbly submit a category to make this less annoying:

@interface NSData (EasyUTF8)

// Safely decode the bytes into a UTF8 string
- (NSString *)asUTF8String;

@end

and

@implementation NSData (EasyUTF8)

- (NSString *)asUTF8String {
    return [[NSString alloc] initWithData:self encoding:NSUTF8StringEncoding];    
}

@end

(Note that if you're not using ARC you'll need an autorelease there.)

Now instead of the appallingly verbose:

NSData *data = ...
[[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];

You can do:

NSData *data = ...
[data asUTF8String];

OBSOLETE ANSWER - VERIFIED NOVEMBER 17, 2020

On Mac, I needed to go to Preferences > Accounts, then add a new account as Bitbucket Server and enter my company's bitbucket server URL. Then I had to choose HTTPS as the protocol and enter my username (without @email) and password.

Also I set this new account as the default account by clicking the Set Default... button in the bottom of the Preferences > Account page.

I'm now using RxJS 5.5.7 in an Angular application and using finalize operator has a weird behavior for my use case since is fired before success or error callbacks.

Simple example:

// Simulate an AJAX callback...
of(null)
  .pipe(
    delay(2000),
    finalize(() => {
      // Do some work after complete...
      console.log('Finalize method executed before "Data available" (or error thrown)');
    })
  )
  .subscribe(
      response => {
        console.log('Data available.');
      },
      err => {
        console.error(err);
      }
  );

I have had to use the add medhod in the subscription to accomplish what I want. Basically a finally callback after the success or error callbacks are done. Like a try..catch..finally block or Promise.finally method.

Simple example:

// Simulate an AJAX callback...
of(null)
  .pipe(
    delay(2000)
  )
  .subscribe(
      response => {
        console.log('Data available.');
      },
      err => {
        console.error(err);
      }
  );
  .add(() => {
    // Do some work after complete...
    console.log('At this point the success or error callbacks has been completed.');
  });

By default EC2 is secured by AWS Security Group (A service found in EC2 and VPC). Security Group by default are disallowing Any ICMP request which includes the ping. To allow it:

Goto: AWS EC2 Instance Locate: The Security Group bind to that instance (It's possible to have multiple security group) Check: Inbound Rules for Protocol (ICMP) Port (0 - 65535) if it's not present you can add it and allow it on your specified source IP or Another Security Group.

If you want to convert string to double data type then most choose parseDouble() method. See the example code:

String str = "123.67";
double d = parseDouble(str);

You will get the value in double. See the StringToDouble tutorial at tutorialData.

I understand that this question is a bit old but I'm going to introduce another solution using redux-observable aka. Epic.

Quoting the official documentation:

What is redux-observable?

RxJS 5-based middleware for Redux. Compose and cancel async actions to create side effects and more.

An Epic is the core primitive of redux-observable.

It is a function which takes a stream of actions and returns a stream of actions. Actions in, actions out.

In more or less words, you can create a function that receives actions through a Stream and then return a new stream of actions (using common side effects such as timeouts, delays, intervals, and requests).

Let me post the code and then explain a bit more about it

store.js

import {createStore, applyMiddleware} from 'redux'
import {createEpicMiddleware} from 'redux-observable'
import {Observable} from 'rxjs'
const NEW_NOTIFICATION = 'NEW_NOTIFICATION'
const QUIT_NOTIFICATION = 'QUIT_NOTIFICATION'
const NOTIFICATION_TIMEOUT = 2000

const initialState = ''
const rootReducer = (state = initialState, action) => {
  const {type, message} = action
  console.log(type)
  switch(type) {
    case NEW_NOTIFICATION:
      return message
    break
    case QUIT_NOTIFICATION:
      return initialState
    break
  }

  return state
}

const rootEpic = (action$) => {
  const incoming = action$.ofType(NEW_NOTIFICATION)
  const outgoing = incoming.switchMap((action) => {
    return Observable.of(quitNotification())
      .delay(NOTIFICATION_TIMEOUT)
      //.takeUntil(action$.ofType(NEW_NOTIFICATION))
  });

  return outgoing;
}

export function newNotification(message) {
  return ({type: NEW_NOTIFICATION, message})
}
export function quitNotification(message) {
  return ({type: QUIT_NOTIFICATION, message});
}

export const configureStore = () => createStore(
  rootReducer,
  applyMiddleware(createEpicMiddleware(rootEpic))
)

index.js

import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';
import {configureStore} from './store.js'
import {Provider} from 'react-redux'

const store = configureStore()

ReactDOM.render(
  <Provider store={store}>
    <App />
  </Provider>,
  document.getElementById('root')
);

App.js

import React, { Component } from 'react';
import {connect} from 'react-redux'
import {newNotification} from './store.js'

class App extends Component {

  render() {
    return (
      <div className="App">
        {this.props.notificationExistance ? (<p>{this.props.notificationMessage}</p>) : ''}
        <button onClick={this.props.onNotificationRequest}>Click!</button>
      </div>
    );
  }
}

const mapStateToProps = (state) => {
  return {
    notificationExistance : state.length > 0,
    notificationMessage : state
  }
}

const mapDispatchToProps = (dispatch) => {
  return {
    onNotificationRequest: () => dispatch(newNotification(new Date().toDateString()))
  }
}

export default connect(mapStateToProps, mapDispatchToProps)(App)

The key code to solve this problem is as easy as pie as you can see, the only thing that appears different from the other answers is the function rootEpic.

Point 1. As with sagas, you have to combine the epics in order to get a top level function that receives a stream of actions and returns a stream of actions, so you can use it with the middleware factory createEpicMiddleware. In our case we only need one so we only have our rootEpic so we don't have to combine anything but it's a good to know fact.

Point 2. Our rootEpic which takes care about the side effects logic only takes about 5 lines of code which is awesome! Including the fact that is pretty much declarative!

Point 3. Line by line rootEpic explanation (in comments)

const rootEpic = (action$) => {
  // sets the incoming constant as a stream 
  // of actions with  type NEW_NOTIFICATION
  const incoming = action$.ofType(NEW_NOTIFICATION)
  // Merges the "incoming" stream with the stream resulting for each call
  // This functionality is similar to flatMap (or Promise.all in some way)
  // It creates a new stream with the values of incoming and 
  // the resulting values of the stream generated by the function passed
  // but it stops the merge when incoming gets a new value SO!,
  // in result: no quitNotification action is set in the resulting stream
  // in case there is a new alert
  const outgoing = incoming.switchMap((action) => {
    // creates of observable with the value passed 
    // (a stream with only one node)
    return Observable.of(quitNotification())
      // it waits before sending the nodes 
      // from the Observable.of(...) statement
      .delay(NOTIFICATION_TIMEOUT)
  });
  // we return the resulting stream
  return outgoing;
}

I hope it helps!

Another point is the time complexity of insert operations. For a list insert, one expects a complexity of O(1). But this could not be guaranteed with a sorted list.

And the most important point is that lists assume nothing about their elements. For example, you can make lists of things that do not implement equals or compare.

Sometimes all it takes to get a EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP, subcode=0x0) is a missing return statement.

It certainly was my case.

You will need to do a couple of things to get this going, since your parameter is getting multiple values you need to create a Table Type and make your store procedure accept a parameter of that type.

Split Function Works Great when you are getting One String containing multiple values but when you are passing Multiple values you need to do something like this....

TABLE TYPE

CREATE TYPE dbo.TYPENAME AS TABLE   (     arg int    )  GO 

Stored Procedure to Accept That Type Param

 CREATE PROCEDURE mainValues   @TableParam TYPENAME READONLY  AS     BEGIN     SET NOCOUNT ON;   --Temp table to store split values   declare @tmp_values table (   value nvarchar(255) not null);        --function splitting values     INSERT INTO @tmp_values (value)    SELECT arg FROM @TableParam      SELECT * FROM @tmp_values  --<-- For testing purpose END 

EXECUTE PROC

Declare a variable of that type and populate it with your values.

 DECLARE @Table TYPENAME     --<-- Variable of this TYPE   INSERT INTO @Table                --<-- Populating the variable   VALUES (331),(222),(876),(932)  EXECUTE mainValues @Table   --<-- Stored Procedure Executed  

Result

╔═══════╗ ║ value ║ ╠═══════╣ ║   331 ║ ║   222 ║ ║   876 ║ ║   932 ║ ╚═══════╝ 

This can be accomplished without any extra properties or method parameters, like so:

public void ConfigureServices(IServiceCollection services)
{
    IServiceProvider serviceProvider = services.BuildServiceProvider();
    IHostingEnvironment env = serviceProvider.GetService<IHostingEnvironment>();

    if (env.IsProduction()) DoSomethingDifferentHere();
}

One of the errors I found around Maven is when I put my settings.xml file in the wrong directory. It has to be in .m2 folder under your user home dir. Check to make sure that is in the right place (along with settings-security.xml if you are using that).

git diff and git apply will work for text files, but won't work for binary files.

You can easily create a full binary patch, but you will have to create a temporary commit. Once you've made your temporary commit(s), you can create the patch with:

git format-patch <options...>

After you've made the patch, run this command:

git reset --mixed <SHA of commit *before* your working-changes commit(s)>

This will roll back your temporary commit(s). The final result leaves your working copy (intentionally) dirty with the same changes you originally had.

On the receiving side, you can use the same trick to apply the changes to the working copy, without having the commit history. Simply apply the patch(es), and git reset --mixed <SHA of commit *before* the patches>.

Note that you might have to be well-synced for this whole option to work. I've seen some errors when applying patches when the person making them hadn't pulled down as many changes as I had. There are probably ways to get it to work, but I haven't looked far into it.

Here's how to create the same patches in Tortoise Git (not that I recommend using that tool):

1. Commit your working changes
2. Right click the branch root directory and click Tortoise Git -> Create Patch Serial
   1. Choose whichever range makes sense (Since: FETCH_HEAD will work if you're well-synced)
   2. Create the patch(es)
3. Right click the branch root directory and click Tortise Git -> Show Log
4. Right click the commit before your temporary commit(s), and click reset "<branch>" to this...
5. Select the Mixed option

And how to apply them:

1. Right click the branch root directory and click Tortoise Git -> Apply Patch Serial
2. Select the correct patch(es) and apply them
3. Right click the branch root directory and click Tortise Git -> Show Log
4. Right click the commit before the patch's commit(s), and click reset "<branch>" to this...
5. Select the Mixed option

One special capability of std::list is splicing (linking or moving part of or a whole list into a different list).

Or perhaps if your contents are very expensive to copy. In such a case it might be cheaper, for example, to sort the collection with a list.

Also note that if the collection is small (and the contents are not particularly expensive to copy), a vector might still outperform a list, even if you insert and erase anywhere. A list allocates each node individually, and that might be much more costly than moving a few simple objects around.

I don't think there are very hard rules. It depends on what you mostly want to do with the container, as well as on how large you expect the container to be and the contained type. A vector generally trumps a list, because it allocates its contents as a single contiguous block (it is basically a dynamically allocated array, and in most circumstances an array is the most efficient way to hold a bunch of things).

To get the value of a pointer, just de-reference the pointer.

int *ptr;
int value;
*ptr = 9;

value = *ptr;

value is now 9.

I suggest you read more about pointers, this is their base functionality.

In the year 2020 / 2021 it is even easier with Array.from to 'convert' from a array-like nodes to an actual array, and then using .map to loop through the resulting array. The code is as simple as the follows:

Array.from(tableFields.children).map((child)=>console.log(child))

Area.replace(new RegExp(/\//g), '-') replaces multiple forward slashes (/) with -

Try to use constructor procedure in your class.

Object.assign

is a key

Please take a look on this sample:

class Employee{
    firstname: string;
    lastname: string;
    birthdate: Date;
    maxWorkHours: number;
    department: string;
    permissions: string;
    typeOfEmployee: string;
    note: string;
    lastUpdate: Date;

    constructor(original: Object) { 
        Object.assign(this, original);
    }
}

let e = new Employee({
    "department": "<anystring>",
    "typeOfEmployee": "<anystring>",
    "firstname": "<anystring>",
    "lastname": "<anystring>",
    "birthdate": "<anydate>",
    "maxWorkHours": 3,
    "username": "<anystring>",
    "permissions": "<anystring>",
    "lastUpdate": "<anydate>"
});
console.log(e);

According to the documentation of the Item property:

Sets or returns an item for a specified key in a Dictionary object.

In your case, you don't have an item whose key is 1 so doing:

s = d.Item(i)

actually creates a new key / value pair in your dictionary, and the value is empty because you have not used the optional newItem argument.

The Dictionary also has the Items method which allows looping over the indices:

a = d.Items
For i = 0 To d.Count - 1
    s = a(i)
Next i

Have a look at using FileInfo.Name Property

something like

string[] files = Directory.GetFiles(dir); 

for (int iFile = 0; iFile < files.Length; iFile++)
    string fn = new FileInfo(files[iFile]).Name;

Also have a look at using DirectoryInfo Class and FileInfo Class

The Exists keyword evaluates true or false, but IN keyword compare all value in the corresponding sub query column. Another one Select 1 can be use with Exists command. Example:

SELECT * FROM Temp1 where exists(select 1 from Temp2 where conditions...)

But IN is less efficient so Exists faster.

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

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

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

Explanation:

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

4.3.8 ‘Local echo’

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

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

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

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

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

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

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

Since in your situation you only want to notify the user with a short and simple message, a Toast would make for a better user experience.

Toast.makeText(getApplicationContext(), "Data saved", Toast.LENGTH_LONG).show();

Update: A Snackbar is recommended now instead of a Toast for Material Design apps.

If you have a more lengthy message that you want to give the reader time to read and understand, then you should use a DialogFragment. (The documentation currently recommends wrapping your AlertDialog in a fragment rather than calling it directly.)

Make a class that extends DialogFragment:

public class MyDialogFragment extends DialogFragment {
    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {

        // Use the Builder class for convenient dialog construction
        AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
        builder.setTitle("App Title");
        builder.setMessage("This is an alert with no consequence");
        builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int id) {
                // You don't have to do anything here if you just 
                // want it dismissed when clicked
            }
        });

        // Create the AlertDialog object and return it
        return builder.create();
    }
}

Then call it when you need it in your activity:

DialogFragment dialog = new MyDialogFragment();
dialog.show(getSupportFragmentManager(), "MyDialogFragmentTag");

Async HTTP client loopj vs. Volley

The specifics of my project are small HTTP REST requests, every 1-5 minutes.

I using an async HTTP client (1.4.1) for a long time. The performance is better than using the vanilla Apache httpClient or an HTTP URL connection. Anyway, the new version of the library is not working for me: library inter exception cut chain of callbacks.

Reading all answers motivated me to try something new. I have chosen the Volley HTTP library.

After using it for some time, even without tests, I see clearly that the response time is down to 1.5x, 2x Volley.

Maybe Retrofit is better than an async HTTP client? I need to try it. But I'm sure that Volley is not for me.

A simple and efficient way, inspired from the implementation of transform in SeqLike.scala

    var i = 0
    xs foreach { el =>
      println("String #" + i + " is " + xs(i))
      i += 1
    }

@RequestMapping(value = "/testonly", method = { RequestMethod.GET, RequestMethod.POST })
public ModelAndView listBooksPOST(@ModelAttribute("booksFilter") BooksFilter filter,
        @RequestParam(required = false) String parameter1,
        @RequestParam(required = false) String parameter2, 
        BindingResult result, HttpServletRequest request) 
        throws ParseException {

    LONG CODE and SAME LONG CODE with a minor difference
}

if @RequestParam(required = true) then you must pass parameter1,parameter2

Use BindingResult and request them based on your conditions.

The Other way

@RequestMapping(value = "/books", method = RequestMethod.GET)
public ModelAndView listBooks(@ModelAttribute("booksFilter") BooksFilter filter,  
    two @RequestParam parameters, HttpServletRequest request) throws ParseException {

    myMethod();

}


@RequestMapping(value = "/books", method = RequestMethod.POST)
public ModelAndView listBooksPOST(@ModelAttribute("booksFilter") BooksFilter filter, 
        BindingResult result) throws ParseException {

    myMethod();

    do here your minor difference
}

private returntype myMethod(){
    LONG CODE
}

In my work we not use macros. So the solution provide by @TomSwift inspired to me. I see the implementation for CGRectMake and create the same CGRectSetPos but without macros.

CG_INLINE CGRect
CGRectSetPos(CGRect frame, CGFloat x, CGFloat y)
{
  CGRect rect;
  rect.origin.x = x; rect.origin.y = y;
  rect.size.width = frame.size.width; rect.size.height = frame.size.height;
  return rect;
}

To use I only put frame, X and Y

viewcontroller.view.frame = CGRectSetPos(viewcontroller.view.frame, 100, 100);

Work for me ^_^

Try swapspace http://pqxx.org/development/swapspace/

Most distros have it packaged.

On EC2 you might want to change "swappath" to /mnt or high-iops disk.

Alternatively, signum() can be used:

if (price.signum() == 0) {
    return true;
}

TCP keepalive and HTTP keepalive are very different concepts. In TCP, the keepalive is the administrative packet sent to detect stale connection. In HTTP, keepalive means the persistent connection state.

This is from TCP specification,

Keep-alive packets MUST only be sent when no data or acknowledgement packets have been received for the connection within an interval. This interval MUST be configurable and MUST default to no less than two hours.

As you can see, the default TCP keepalive interval is too long for most applications. You might have to add keepalive in your application protocol.

Run:

go mod init yellow

Then create a file yellow.go:

package yellow

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

Then create a file orange/orange.go:

package main
import "yellow"

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

Then build:

go build

Per the Android docs SystemClock.elapsedRealtime() is the recommend basis for general purpose interval timing. This is because, per the documentation, elapsedRealtime() is guaranteed to be monotonic, [...], so is the recommend basis for general purpose interval timing.

The SystemClock documentation has a nice overview of the various time methods and the applicable use cases for them.

• SystemClock.elapsedRealtime() and SystemClock.elapsedRealtimeNanos() are the best bet for calculating general purpose elapsed time.
• SystemClock.uptimeMillis() and System.nanoTime() are another possibility, but unlike the recommended methods, they don't include time in deep sleep. If this is your desired behavior then they are fine to use. Otherwise stick with elapsedRealtime().
• Stay away from System.currentTimeMillis() as this will return "wall" clock time. Which is unsuitable for calculating elapsed time as the wall clock time may jump forward or backwards. Many things like NTP clients can cause wall clock time to jump and skew. This will cause elapsed time calculations based on currentTimeMillis() to not always be accurate.

When the game starts:

long startTime = SystemClock.elapsedRealtime();

When the game ends:

long endTime = SystemClock.elapsedRealtime();
long elapsedMilliSeconds = endTime - startTime;
double elapsedSeconds = elapsedMilliSeconds / 1000.0;

Also, Timer() is a best effort timer and will not always be accurate. So there will be an accumulation of timing errors over the duration of the game. To more accurately display interim time, use periodic checks to System.currentTimeMillis() as the basis of the time sent to setText(...).

Also, instead of using Timer, you might want to look into using TimerTask, this class is designed for what you want to do. The only problem is that it counts down instead of up, but that can be solved with simple subtraction.

update registry path to installation location

This happened for me when I moved out my default installation from an overcrowded primary partition to another location. Fir

Yes, session doesn't go hand in hand with Rest API and also we should avoid this practices. But as per requirements we need to maintain session somehow such that in every request client server can exchange or maintain state or data. So, the best way to achieve this without breaking the REST protocols is communicate through token like JWT.

You try to instantiate an object of the Friends class like this:

Friends f = new Friends(friendsName, friendsAge);

The class does not have a constructor that takes parameters. You should either add the constructor, or create the object using the constructor that does exist and then use the set-methods. For example, instead of the above:

Friends f = new Friends();
f.setName(friendsName);
f.setAge(friendsAge);

This wiki page has this interesting one-liner, which reminds us that we can push several refs:

git push origin refs/tags/<old-tag>:refs/tags/<new-tag> :refs/tags/<old-tag> && git tag -d <old-tag>

and ask other cloners to do git pull --prune --tags

So the idea is to push:

• <new-tag> for every commits referenced by <old-tag>: refs/tags/<old-tag>:refs/tags/<new-tag>,
• the deletion of <old-tag>: :refs/tags/<old-tag>

See as an example "Change naming convention of tags inside a git repository?".

I know this already has a marked answer, but I feel I have an improvement to it.

The marked answer is a bit misleading. He set a width to the button, which is not necessary, and set widths are not "responsive". To his defense, he mentions in a comment below it, that the width is not necessary and just an example.

One thing not mentioned here, is that the words may break in the middle of a word and look messed up.

My solution, forces the break to happen between words, a nice word wrap.

.btn-responsive {
    white-space: normal !important;
    word-wrap: break-word;
}

<a href="#" class="btn btn-primary btn-responsive">Click Here</a>

$user->data is an array of objects. Each element in the array has a name and value property (as well as others).

Try putting the 2nd foreach inside the 1st.

foreach($user->data as $mydata)
{
    echo $mydata->name . "\n";
    foreach($mydata->values as $values)
    {
        echo $values->value . "\n";
    }
}

    printf("%8d\n",1);
    printf("%8d\n",10);
    printf("%8d\n",100);
    printf("%8d\n",1000);

I was able to resolve the problem by following steps: a. upgrade to the latest chrome version, clear the cache and close the chrome browser b. Download latest Selenium 3.0

You can try using Putty (freeware). It is mainly known as a SSH client, but you can use for Telnet login as well

• What database types had caused to you, as a developer, more trouble to understand and debug? Expected answer, IMHO, experience with issues using different date/timestamp types and BLOBs.

• When is convenient to use bitmap indexes?

I guess the following code will help:

var refreshIntervalId = setInterval(fname, 10000);

clearInterval(refreshIntervalId);

You did the code 100% correct... So... What's the problem? Or it's a tutorial...

This is because the original A activity is already being destroyed by the time you start it from B, C or D. Therefore, onCreate will be called in stead of onNewIntent(). One way of solving this is to always destroy the existing A(using FLAG_ACTIVITY_CLEAR_TASK | FLAG_ACTIVITY_NEW_TASK conjunction when startActivity) before starting a new A, so onCreate will always be called, and you put the code of onNewIntent() into onCreate by checking if getIntent() is the intent you started with.

http://transfonter.org/ will do the job for you. Just upload your .ttc and it will give you a folder with all the fonttypes in .ttf files.

If you prefer not to use regex, you might try

''.join([i for i in s if i.isalpha()])

After struggling with the same problem, I tried two different solutions that works:

1. Use double quotes ("") with your variables.

Easiest way just double quotes your variables as pointed in previous answer:

cd "$yourPathWithBlankSpace"

2. Make use of eval.

According to this answer Unix command to escape spaces you can strip blank space then make use of eval, like this:

yourPathEscaped=$(printf %q "$yourPathWithBlankSpace")
eval cd $yourPathEscaped

I am also faced same problem.

If you're adding a new field then it gives the error as no column found.

Then you apply make migration command and after that migrate command Then still same error.. EX...

 path=models.FilePathField()

Add default value for field

  path=models.FilePathField(default='')

and than apply command

  python manage.py makemigrations

  python manage.py migrate

It may help you

This is the simplest and easy way. This is how we do this.

var obj = { 'bar' : 'baz' }_x000D_
var key = Object.keys(obj)[0];_x000D_
var value = obj[key];_x000D_
     _x000D_
 console.log("key = ", key) // bar_x000D_
 console.log("value = ", value) // baz

Object.keys(obj) // ['bar']

Now you can iterate on the objects and can access values like below-

Object.keys(obj).forEach( function(key) {
  console.log(obj[key]) // baz
})

You can't get the file size of local files with javascript in a standard way using a web browser.

But if the file is accessible from a remote path, you might be able to send a HEAD request using Javascript, and read the Content-length header, depending on the webserver

I am supporting iOS 5, 6, & 7. My app is iPad only. I needed to use all of the following:

[[UIApplication sharedApplication] setStatusBarHidden:YES];

View Controller:

- (BOOL)prefersStatusBarHidden{ return YES; }

Info.plist

    <key>UIStatusBarHidden</key>
    <string>YES</string>

Using the inline-block is better because it doesn't force the remaining elements and/or controls to be drawn in a new line.

label {
  width:200px;
  display: inline-block;
}

I also had the similar issue. Logs were not creating.

I did not see any reference to Raphael.js. So I thought I'd include it here. Raphael.js is backwards compatible all the way back to IE5 and a very early Firefox as well as all of the rest of the browsers. It uses SVG when it can and VML when it can not. What you do with it is to draw onto a canvas. Some browsers will even let you select the text that is generated. Raphael.js can be found here:

http://raphaeljs.com/

It can be as simple as creating your paper drawing area, specifying the font, font-weight, size, etc... and then telling it to put your string of text onto the paper. I am not sure if it gets around the licensing issues or not but it is drawing the text so I'm fairly certain it does circumvent the licensing issues. But check with your lawyer to be sure. :-)

To create a "drop down menu" you can use OptionMenu in tkinter

Example of a basic OptionMenu:

from Tkinter import *

master = Tk()

variable = StringVar(master)
variable.set("one") # default value

w = OptionMenu(master, variable, "one", "two", "three")
w.pack()

mainloop()

More information (including the script above) can be found here.

Creating an OptionMenu of the months from a list would be as simple as:

from tkinter import *

OPTIONS = [
"Jan",
"Feb",
"Mar"
] #etc

master = Tk()

variable = StringVar(master)
variable.set(OPTIONS[0]) # default value

w = OptionMenu(master, variable, *OPTIONS)
w.pack()

mainloop()

In order to retrieve the value the user has selected you can simply use a .get() on the variable that we assigned to the widget, in the below case this is variable:

from tkinter import *

OPTIONS = [
"Jan",
"Feb",
"Mar"
] #etc

master = Tk()

variable = StringVar(master)
variable.set(OPTIONS[0]) # default value

w = OptionMenu(master, variable, *OPTIONS)
w.pack()

def ok():
    print ("value is:" + variable.get())

button = Button(master, text="OK", command=ok)
button.pack()

mainloop()

I would highly recommend reading through this site for further basic tkinter information as the above examples are modified from that site.

Polymorphism simply means "Many Forms".

It does not REQUIRE inheritance to achieve...as interface implementation, which is not inheritance at all, serves polymorphic needs. Arguably, interface implementation serves polymorphic needs "Better" than inheritance.

For example, would you create a super-class to describe all things that can fly? I should think not. You would be be best served to create an interface that describes flight and leave it at that.

So, since interfaces describe behavior, and method names describe behavior (to the programmer), it is not too far of a stretch to consider method overloading as a lesser form of polymorphism.

You can also just send the user name by writing:

curl -u USERNAME http://server.example

Curl will then ask you for the password, and the password will not be visible on the screen (or if you need to copy/paste the command).

Usually you restore your state in onCreate(). It is possible to restore it in onRestoreInstanceState() as well, but not very common. (onRestoreInstanceState() is called after onStart(), whereas onCreate() is called before onStart().

Use the put methods to store values in onSaveInstanceState():

protected void onSaveInstanceState(Bundle icicle) {
  super.onSaveInstanceState(icicle);
  icicle.putLong("param", value);
}

And restore the values in onCreate():

public void onCreate(Bundle icicle) {
  if (icicle != null){
    value = icicle.getLong("param");
  }
}

I found this article

  /// <summary>
    /// Creates a new Image containing the same image only rotated
    /// </summary>
    /// <param name=""image"">The <see cref=""System.Drawing.Image"/"> to rotate

    public static Bitmap RotateImage(Image image, PointF offset, float angle)
    {
        if (image == null)
            throw new ArgumentNullException("image");

        //create a new empty bitmap to hold rotated image
        Bitmap rotatedBmp = new Bitmap(image.Width, image.Height);
        rotatedBmp.SetResolution(image.HorizontalResolution, image.VerticalResolution);

        //make a graphics object from the empty bitmap
        Graphics g = Graphics.FromImage(rotatedBmp);

        //Put the rotation point in the center of the image
        g.TranslateTransform(offset.X, offset.Y);

        //rotate the image
        g.RotateTransform(angle);

        //move the image back
        g.TranslateTransform(-offset.X, -offset.Y);

        //draw passed in image onto graphics object
        g.DrawImage(image, new PointF(0, 0));

        return rotatedBmp;
    }

Just tried it. the answer is -> out-of-range integer as a 2-byte value: 32768

Have you tried this?

$('.myClass, .myOtherClass').removeClass('theclass');

Dim text As String = "123.45"
Dim value As Double
If Double.TryParse(text, value) Then
    ' text is convertible to Double, and value contains the Double value now
Else
    ' Cannot convert text to Double
End If

Here's my edit to this excellent answer - with added ability to parse query strings with keys without values.

var url = 'http://sb.com/reg/step1?param';
var qs = (function(a) {
    if (a == "") return {};
    var b = {};
    for (var i = 0; i < a.length; ++i) {
        var p=a[i].split('=', 2);
        if (p[1]) p[1] = decodeURIComponent(p[1].replace(/\+/g, " "));
        b[p[0]] = p[1];
    }
    return b;
})((url.split('?'))[1].split('&'));

IMPORTANT! The parameter for that function in the last line is different. It's just an example of how one can pass an arbitrary URL to it. You can use last line from Bruno's answer to parse the current URL.

So what exactly changed? With url http://sb.com/reg/step1?param= results will be same. But with url http://sb.com/reg/step1?param Bruno's solution returns an object without keys, while mine returns an object with key param and undefined value.

''Alastair, you can use this lib and tool; DefiantJS. It enables XPath queries on JSON structures and you can test and validate this XPath:

//data[category="Politician"]

DefiantJS extends the global object with the method "search", which in turn returns an array with the matches. In Javascript, it'll look like this:

var person = JSON.search(json_data, "//people[category='Politician']");
console.log( person[0].name );
// Barack Obama

You can write 2 simple functions that actually turns out to be about 5-8 times faster than using scipy.special.comb. In fact, you don't need to import any extra packages, and the function is quite easily readable. The trick is to use memoization to store previously computed values, and using the definition of nCr

# create a memoization dictionary
memo = {}
def factorial(n):
    """
    Calculate the factorial of an input using memoization
    :param n: int
    :rtype value: int
    """
    if n in [1,0]:
        return 1
    if n in memo:
        return memo[n]
    value = n*factorial(n-1)
    memo[n] = value
    return value

def ncr(n, k):
    """
    Choose k elements from a set of n elements - n must be larger than or equal to k
    :param n: int
    :param k: int
    :rtype: int
    """
    return factorial(n)/(factorial(k)*factorial(n-k))

If we compare times

from scipy.special import comb
%timeit comb(100,48)
>>> 100000 loops, best of 3: 6.78 µs per loop

%timeit ncr(100,48)
>>> 1000000 loops, best of 3: 1.39 µs per loop

This should work for you. Infact the one which you are thinking will also work:-

 .......
 DECLARE @returnvalue INT

 EXEC @returnvalue = SP_One
 .....

Caucho Quercus can run PHP code on the jvm.

For that kind of behavior I always use the jQueryUI button widget, I use it for links and buttons.

Define the tag within HTML:

<button id="sampleButton">Sample Button</button>
<a id="linkButton" href="yourHttpReferenceHere">Link Button</a>

Use jQuery to initialize the buttons:

$("#sampleButton").button();
$("#linkButton").button();

Use the button widget methods to disable/enable them:

$("#sampleButton").button("enable"); //enable the button
$("#linkButton").button("disable"); //disable the button

That will take care of the button and cursor behavior, but if you need to get deeper and change the button style when disabled then overwrite the following CSS classes within your page CSS style file.

.ui-state-disabled,
.ui-widget-content .ui-state-disabled,
.ui-widget-header .ui-state-disabled {
      background-color:aqua;
      color:black;
 }

But remember: those CSS classes (if changed) will change the style for other widgets too.

The following will work in MVC 4

@Html.HiddenFor(x => x.CRN, new { @Value = "1" });

@Value property is case sensitive. You need a capital 'V' on @Value.

Here is my model

public int CRN { get; set; }

Here is what is output in html when you look in the browser

<input value="1" data-val="true" data-val-number="The field CRN must be a number." data-val-required="The CRN field is required." id="CRN" name="CRN" type="hidden" value="1"/>

Here is my method

[HttpPost]
public ActionResult MyMethod(MyViewModel viewModel)
{
  int crn = viewModel.CRN;
}

Try this

 SELECT *
 FROM people P 
 where P.IDNo in (SELECT DISTINCT IDNo
              FROM people)

In MRI 1.8.7 or greater:

'foobarbaz'.each_char.first

Another way to define a 2-d vector is to declare a vector of pair's.

 vector < pair<int,int> > v;

**To insert values**
 cin >> x >>y;
 v.push_back(make_pair(x,y));

**Retrieve Values**
 i=0 to size(v)
 x=v[i].first;
 y=v[i].second;

For 3-d vectors take a look at tuple and make_tuple.

When the above solution doesn’t work try this:

<IfModule mod_security.c>
  SecRuleEngine Off
  SecFilterInheritance Off
  SecFilterEngine Off
  SecFilterScanPOST Off
  SecRuleRemoveById 300015 3000016 3000017
</IfModule>

The default string representation for a dictionary seems to be just right:

>>> a={3: 'foo', 17: 'bar' }
>>> a
{17: 'bar', 3: 'foo'}
>>> print a
{17: 'bar', 3: 'foo'}
>>> print "a=", a
a= {17: 'bar', 3: 'foo'}

Not sure if you can get at the "variable name", since variables in Python are just labels for values. See this question.

Try to combine the query, it will run much faster than executing an additional query per row. Ik don't like the string[] you're using, i would create a class for holding the information.

    public List<string[]> get_dados_historico_verificacao_email_WEB(string email)
    {
        List<string[]> historicos = new List<string[]>();

        using (SqlConnection conexao = new SqlConnection("ConnectionString"))
        {
            string sql =
                @"SELECT    *, 
                            (   SELECT      COUNT(e.cd_historico_verificacao_email) 
                                FROM        emails_lidos e 
                                WHERE       e.cd_historico_verificacao_email = a.nm_email ) QT
                  FROM      historico_verificacao_email a
                  WHERE     nm_email = @email
                  ORDER BY  dt_verificacao_email DESC, 
                            hr_verificacao_email DESC";

            using (SqlCommand com = new SqlCommand(sql, conexao))
            {
                com.Parameters.Add("email", SqlDbType.VarChar).Value = email;

                SqlDataReader dr = com.ExecuteReader();

                while (dr.Read())
                {
                    string[] dados_historico = new string[6];
                    dados_historico[0] = dr["nm_email"].ToString();
                    dados_historico[1] = dr["dt_verificacao_email"].ToString();
                    dados_historico[1] = dados_historico[1].Substring(0, 10);
                    //System.Windows.Forms.MessageBox.Show(dados_historico[1]);
                    dados_historico[2] = dr["hr_verificacao_email"].ToString();
                    dados_historico[3] = dr["ds_tipo_verificacao"].ToString();
                    dados_historico[4] = dr["QT"].ToString();
                    dados_historico[5] = dr["cd_login_usuario"].ToString();

                    historicos.Add(dados_historico);
                }
            }
        }
        return historicos;
    }

Untested, but maybee gives some idea.

The readonly keyword is used to declare a member variable a constant, but allows the value to be calculated at runtime. This differs from a constant declared with the const modifier, which must have its value set at compile time. Using readonly you can set the value of the field either in the declaration, or in the constructor of the object that the field is a member of.

Also use it if you don't want to have to recompile external DLLs that reference the constant (since it gets replaced at compile time).

I had a similar problem. I wanted to move files and folder structures and overwrite existing files, but not delete anything which is in the destination folder structure.

I solved it by using os.walk(), recursively calling my function and using shutil.move() on files which I wanted to overwrite and folders which did not exist.

It works like shutil.move(), but with the benefit that existing files are only overwritten, but not deleted.

import os
import shutil

Acked Unseen sample

Hi guys! Just some observations from what I just found in my capture:

On many occasions, the packet capture reports “ACKed segment that wasn't captured” on the client side, which alerts of the condition that the client PC has sent a data packet, the server acknowledges receipt of that packet, but the packet capture made on the client does not include the packet sent by the client

Initially, I thought it indicates a failure of the PC to record into the capture a packet it sends because “e.g., machine which is running Wireshark is slow” (https://osqa-ask.wireshark.org/questions/25593/tcp-previous-segment-not-captured-is-that-a-connectivity-issue)
However, then I noticed every time I see this “ACKed segment that wasn't captured” alert I can see a record of an “invalid” packet sent by the client PC

• In the capture example above, frame 67795 sends an ACK for 10384

• Even though wireshark reports Bogus IP length (0), frame 67795 is reported to have length 13194

• Frame 67800 sends an ACK for 23524
• 10384+13194 = 23578
• 23578 – 23524 = 54
• 54 is in fact length of the Ethernet / IP / TCP headers (14 for Ethernt, 20 for IP, 20 for TCP)
• So in fact, the frame 67796 does represent a large TCP packets (13194 bytes) which operating system tried to put on the wore
  • NIC driver will fragment it into smaller 1500 bytes pieces in order to transmit over the network
  • But Wireshark running on my PC fails to understand it is a valid packet and parse it. I believe Wireshark running on 2012 Windows server reads these captures correctly
• So after all, these “Bogus IP length” and “ACKed segment that wasn't captured” alerts were in fact false positives in my case

$date = strtotime(date("Y-m-d", strtotime($date)) . " +1 day");

Or, simplier:

date("Y-m-d H:i:s", time()+((60*60)*24));

If you removed the make all line from your "fresh" target:

fresh :
    rm -f *.o $(EXEC)
    clear

You could simply run the command make fresh all, which will execute as make fresh; make all.

Some might consider this as a second instance of make, but it's certainly not a sub-instance of make (a make inside of a make), which is what your attempt seemed to result in.

Two problems:

1. Your function does not return anything; a function that does not explicitly return anything returns None (which is falsy)

2. True is always True - you are not checking the result of your function

.

def check(fname, txt):
    with open(fname) as dataf:
        return any(txt in line for line in dataf)

if check('example.txt', 'blabla'):
    print "true"
else:
    print "false"

An intuitive way to think about this is that if you had a full balanced binary search tree, then the root would be the median element, since there there would be the same number of smaller and greater elements. Now, if the tree isn't full this won't be quite the case since there will be elements missing from the last level.

So what we can do instead is have the median, and two balanced binary trees, one for elements less than the median, and one for elements greater than the median. The two trees must be kept at the same size.

When we get a new integer from the data stream, we compare it to the median. If it's greater than the median, we add it to the right tree. If the two tree sizes differ more than 1, we remove the min element of the right tree, make it the new median, and put the old median in the left tree. Similarly for smaller.

You can consider using memory-mapped files, via FileChannels .

Generally a lot faster for large files. There are performance trade-offs that could make it slower, so YMMV.

This is really late to the party, but none of the solutions above worked for me. I didn't want the "Found total xxx records" so I added info:false to the config. When I removed that everything worked.

I should note that the first page loaded fine. When I hit next, the second page loaded, but immediately threw the above console error

The :before pseudo element isn't needed for the clearfix hack itself.

It's just an additional nice feature helping to prevent margin-collapsing of the first child element. Thus the top margin of an child block element of the "clearfixed" element is guaranteed to be positioned below the top border of the clearfixed element.

display:table is being used because display:block doesn't do the trick. Using display:block margins will collapse even with a :before element.

There is one caveat: if vertical-align:baseline is used in table cells with clearfixed <div> elements, Firefox won't align well. Then you might prefer using display:block despite loosing the anti-collapsing feature. In case of further interest read this article: Clearfix interfering with vertical-align.

This article describes how to render text in OpenGL using various techniques.

With only using opengl, there are several ways:

• using glBitmap
• using textures
• using display lists

In simple words, order() gives the locations of elements of increasing magnitude.

For example, order(c(10,20,30)) will give 1,2,3 and order(c(30,20,10)) will give 3,2,1.

For creating session only cookie with java script, you can use the following. This works for me.

document.cookie = "cookiename=value; expires=0; path=/";

then get cookie value as following

 //get cookie 
var cookiename = getCookie("cookiename");
if (cookiename == "value") {
    //write your script
}

//function getCookie        
function getCookie(cname) {
    var name = cname + "=";
    var ca = document.cookie.split(';');
    for (var i = 0; i < ca.length; i++) {
        var c = ca[i];
        while (c.charAt(0) == ' ') c = c.substring(1);
        if (c.indexOf(name) != -1) return c.substring(name.length, c.length);
    }
    return "";
}

Okay to support IE we can leave "expires" completely and can use this

document.cookie = "mtracker=somevalue; path=/";

Here I think it's worth mentioning SORT BY and ORDER BY both clauses and why they different,

SELECT * FROM <table_name> SORT BY <column_name> DESC LIMIT 2

If you are using SORT BY clause it sort data per reducer which means if you have more than one MapReduce task it will result partially ordered data. On the other hand, the ORDER BY clause will result in ordered data for the final Reduce task. To understand more please refer to this link.

SELECT * FROM <table_name> ORDER BY <column_name> DESC LIMIT 2

Note: Finally, Even though the accepted answer contains SORT BY clause, I mostly prefer to use ORDER BY clause for the general use case to avoid any data loss.

I had this error in tests, the directive templateUrl wasn't trusted, but only for the spec, so I added the template directory:

beforeEach(angular.mock.module('app.templates'));

My main directory is app.

You can add "issue time" to token and maintain "last logout time" for each user on the server. When you check token validity, also check "issue time" be after "last logout time".

This is not a direct answer, but very useful if you don't have access to how java starts: you can set the environment variable JAVA_TOOLS_OPTIONS to -Dfile.encoding="UTF-8" and every time the jvm starts it will pick up that option.

Until version 4.6

The dash type of a linestyle is given by the linetype, which does also select the line color unless you explicitely set an other one with linecolor.

However, the support for dashed lines depends on the selected terminal:

1. Some terminals don't support dashed lines, like png (uses libgd)
2. Other terminals, like pngcairo, support dashed lines, but it is disables by default. To enable it, use set termoption dashed, or set terminal pngcairo dashed ....
3. The exact dash patterns differ between terminals. To see the defined linetype, use the test command:

Running

set terminal pngcairo dashed
set output 'test.png'
test
set output

gives:

whereas, the postscript terminal shows different dash patterns:

set terminal postscript eps color colortext
set output 'test.eps'
test
set output

Version 5.0

Starting with version 5.0 the following changes related to linetypes, dash patterns and line colors are introduced:

• A new dashtype parameter was introduced:

  To get the predefined dash patterns, use e.g.

  plot x dashtype 2
  

  You can also specify custom dash patterns like

  plot x dashtype (3,5,10,5),\
       2*x dashtype '.-_'
  

• The terminal options dashed and solid are ignored. By default all lines are solid. To change them to dashed, use e.g.

  set for [i=1:8] linetype i dashtype i
  

• The default set of line colors was changed. You can select between three different color sets with set colorsequence default|podo|classic:

When I run your code, I get the following output for example.

<usb.Device object at 0xef38c0>
Device: 001
  idVendor: 7531 (0x1d6b)
  idProduct: 1 (0x0001)
Manufacturer: 3
Serial: 1
Product: 2

Noteworthy are that a) I have usb.Device objects whereas you have usb.legacy.Device objects, and b) I have device filenames.

Each usb.Bus has a dirname field and each usb.Device has the filename. As you can see, the filename is something like 001, and so is the dirname. You can combine these to get the bus file. For dirname=001 and filname=001, it should be something like /dev/bus/usb/001/001.

You should first, though figure out what this "usb.legacy" situation is. I'm running the latest version and I don't even have a legacy sub-module.

Finally, you should use the idVendor and idProduct fields to uniquely identify the device when it's plugged in.

Still if you need to remove padding from .row and immediate child columns you have to add the class .no-gutters with the code from @Brian above to your own CSS file, actually it's Not 'right out of the box', check here for official details on the final Bootstrap 4 release: https://getbootstrap.com/docs/4.0/layout/grid/#no-gutters

Let's say you have a script script.sh. To run it (using Git Bash), you do the following: [a] Add a "sh-bang" line on the first line (e.g. #!/bin/bash) and then [b]:

# Use ./ (or any valid dir spec):
./script.sh

Note: chmod +x does nothing to a script's executability on Git Bash. It won't hurt to run it, but it won't accomplish anything either.

The lock screen works without keyguard i have tested it. The home button stops working and you can't get to task manager by holding the home key. I wish they didn't develop a new process when it used to be built into system ui or whatever. I don't see the need for the change and extra process

You have to set the associatedEmployee on the Vehicle before persisting the Employee.

Employee newEmployee = new Employee("matt");
vehicle1.setAssociatedEmployee(newEmployee);
vehicles.add(vehicle1);

newEmployee.setVehicles(vehicles);

Employee savedEmployee = employeeDao.persistOrMerge(newEmployee);

I had an issue with turning off a background image (a DRAFT watermark) in VBA. My change wasn't showing up (which was performed with the Sheets(1).PageSetup.CenterHeader = "" method) - so I needed a way to refresh. The ActiveSheet.EnableCalculation approach partly did the trick, but didn't cover unused cells.

In the end I found what I needed with a one liner that made the image vanish when it was no longer set :-

Application.ScreenUpdating = True

Import datetime and timedelta:

>>> from datetime import datetime, timedelta
>>> str(datetime.now() + timedelta(hours=9))[11:19]
'01:41:44'

But the better way is:

>>> (datetime.now() + timedelta(hours=9)).strftime('%H:%M:%S')
'01:42:05'

You can refer strptime and strftime behavior to better understand how python processes dates and time field

For background images, make sure to use url()

node.backgroundImage = 'url(' + e.target.result + ')';

Needed to replace non-alphanumeric characters rather than remove non-alphanumeric characters so I have created this based on Ryan Shillington's alphanum. Works for strings up to 255 characters in length

DROP FUNCTION IF EXISTS alphanumreplace; 
DELIMITER | 
CREATE FUNCTION alphanumreplace( str CHAR(255), d CHAR(32) ) RETURNS CHAR(255) 
BEGIN 
  DECLARE i, len SMALLINT DEFAULT 1; 
  DECLARE ret CHAR(32) DEFAULT ''; 
  DECLARE c CHAR(1); 
  SET len = CHAR_LENGTH( str ); 
  REPEAT 
    BEGIN 
      SET c = MID( str, i, 1 ); 
      IF c REGEXP '[[:alnum:]]' THEN SET ret=CONCAT(ret,c); 
      ELSE SET ret=CONCAT(ret,d);
      END IF; 
      SET i = i + 1; 
    END; 
  UNTIL i > len END REPEAT; 
  RETURN ret; 
END | 
DELIMITER ; 

Example:

select 'hello world!',alphanum('hello world!'),alphanumreplace('hello world!','-');
+--------------+--------------------------+-------------------------------------+
| hello world! | alphanum('hello world!') | alphanumreplace('hello world!','-') |
+--------------+--------------------------+-------------------------------------+
| hello world! | helloworld               | hello-world-                        |
+--------------+--------------------------+-------------------------------------+

You'll need to add the alphanum function seperately if you want that, I just have it here for the example.

PHP has its own inbuilt class that can be used to unzip or extracts contents from a zip file. The class is ZipArchive. Below is the simple and basic PHP code that will extract a zip file and place it in a specific directory:

<?php
$zip_obj = new ZipArchive;
$zip_obj->open('dummy.zip');
$zip_obj->extractTo('directory_name/sub_dir');
?>

If you want some advance features then below is the improved code that will check if the zip file exists or not:

<?php
$zip_obj = new ZipArchive;
if ($zip_obj->open('dummy.zip') === TRUE) {
   $zip_obj->extractTo('directory/sub_dir');
   echo "Zip exists and successfully extracted";
}
else {
   echo "This zip file does not exists";
}
?>

This problem happens as a result of calling a method without brackets. Take a look at the example below:

class SomeClass(object):
    def __init__(self):
        print 'I am starting'

    def some_meth(self):
        print 'I am a method()'

x = SomeClass()
''' Not adding the bracket after the method call would result in method bound error '''
print x.some_meth
''' However this is how it should be called and it does solve it '''
x.some_meth()

cast (field1 as decimal(53,8)
) field 1

The default is: decimal(18,0)

I came here looking for the answer to the same question. But I found a much better answer myself.

In the tables list, if you right-click on the table name there is a suite of CRUD script generation options in "Send to SQL Editor". You can select multiple tables and take the same approach too.

My version of MySQL Workbench: 5.2.37

It looks like you forgot the prefix on the color attribute. Try

 <stroke android:width="2dp" android:color="#ff00ffff"/>

Remove the padding:

padding-left: 0;

You can also use the xattr command as in Stack Overflow question How do I remove the "extended attributes" on a file in Mac OS X?.

Just remove the com.apple.quarantine attribute. It works even if you don't have an administrator account, which can be a plus. After that, the app isn't considered "downloaded" and is therefore not blocked.

The problem is that you're displaying time(), which is a UNIX timestamp based on GMT/UTC. That’s why it doesn’t change. date() on the other hand, formats the time based on that timestamp.

A timestamp is the number of seconds since the Unix Epoch (January 1 1970 00:00:00 GMT).

echo date('Y-m-d H:i:s T', time()) . "<br>\n";
date_default_timezone_set('UTC');
echo date('Y-m-d H:i:s T', time()) . "<br>\n";

In Arch Linux using a UK keyboard and locale, I had the following error:

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
LANGUAGE = (unset),
LC_ALL = (unset),
LANG = "en_US.utf8"

• Exporting my locales in /etc/profile didn't fix it.

• I did however fix this by editing /etc/locale.gen, also enabling the en_US.utf8 locale that perl expected to find, and running local-gen.

(I use pac-manager which uses a whole bunch of perl modules from AUR, so reinstalling perl in my particular case would be a nuisance.)

Just do tr delete:

tr -d "\r" <infile.txt >outfile.txt

To read the data line-by-line into a Bash array you can do this:

while read -a row
do
    echo "..${row[0]}..${row[1]}..${row[2]}.."
done < <(echo "SELECT A, B, C FROM table_a" | mysql database -u $user -p $password)

Or into individual variables:

while read a b c
do
    echo "..${a}..${b}..${c}.."
done < <(echo "SELECT A, B, C FROM table_a" | mysql database -u $user -p $password)

I solved my z-index problem by making the body wrapper z-index:-1 and the body z-index:-2, and the other divs z-index:1.

And then the later divs didn't work unless I had z-index 200+. Even though I had position:relative on each element, with the body at default z-index it wouldn't work.

Hope this helps somebody.

Drive mapping to sharepoint (also https)

Getting sharepoint contents worked for me via the mapped drive iterating it as a filesystem object; trick is how to set up the mapping: Then copy path (line with http*) (see below)

Use this path in Map drive from explorer or command (i.e. net use N: https:://thepathyoujustcopied) Note: https works ok with windows7/8, not with XP.

That may work for you, but I prefer a different approach as drive letters are different on each pc. The trick here is to start from sharepoint (and not from a VBA script accessing sharepoint as a web server).

Set up a data connection to excel sheet

• in sharepoint, browse to the view you want to monitor
• export view to excel (in 2010: library tools; libarry | export to Excel)
• when viewing this excel, you'll find a datasource set up (tab: data, connections, properties, definition)

You can either include this query in vba, or maintain the database link in your speadsheet, iterating over the table by VBA. Please note: the image above does not show the actual database connection (command text), which would tell you how to access my sharepoint.

document.getElementById('textbox-id').readOnly=true should work

Here is a query, you can run it in SQL Developer (or SQL*Plus):

SELECT DS.TABLESPACE_NAME, SEGMENT_NAME, ROUND(SUM(DS.BYTES) / (1024 * 1024)) AS MB
  FROM DBA_SEGMENTS DS
  WHERE SEGMENT_NAME IN (SELECT TABLE_NAME FROM DBA_TABLES)
 GROUP BY DS.TABLESPACE_NAME,
       SEGMENT_NAME;

In JBoss Developer 4.0 and above (Eclipse-based), this is a tad easier. Just right-click on your file or folder that contains xml-based files, choose "Exclude Validation", then click "Yes" to confirm. Then right-click the same files/folder again and click on "Validate", which will remove the errors with a confirmation.

add layout_gravity="center" or "center_horizontal" to the parent layout.

On a side note, your LinearLayout inside your TableRow seems un-necessary, as a TableRow is already an horizontal LinearLayout.

You only need [] to instantiate an array - this is true regardless of its type. The fact that the array is of an array type is immaterial.

The same thing applies at the first level in your loop. It is merely an array and [] is a new empty array - job done.

As for the second level, if Thing is a class then new Thing() will be just fine. Otherwise, depending on the type, you may need a factory function or other expression to create one.

class Something {
    private things: Thing[][];

    constructor() {
        this.things = [];

        for(var i: number = 0; i < 10; i++) {
            this.things[i] = [];
            for(var j: number = 0; j< 10; j++) {
                this.things[i][j] = new Thing();

cors unblock works great for chrome 78 [COrs unb] [1] https://chrome.google.com/webstore/detail/cors-unblock/lfhmikememgdcahcdlaciloancbhjino

it's a plugin for google chrome called "cors unblock"

Summary: No more CORS error by appending 'Access-Control-Allow-Origin: *' header to local and remote web requests when enabled

This extension provides control over XMLHttpRequest and fetch methods by providing custom "access-control-allow-origin" and "access-control-allow-methods" headers to every requests that the browser receives. A user can toggle the extension on and off from the toolbar button. To modify how these headers are altered, use the right-click context menu items. You can customize what method are allowed. The default option is to allow 'GET', 'PUT', 'POST', 'DELETE', 'HEAD', 'OPTIONS', 'PATCH' methods. You can also ask the extension not to overwrite these headers when the server already fills them.

More things can be done with keyboard module. You can install this module using pip install keyboard Here are some of the methods:

Method #1:

Using the function read_key():

import keyboard

while True:
    if keyboard.read_key() == "p":
        print("You pressed p")
        break

This is gonna break the loop as the key p is pressed.

Method #2:

Using function wait:

import keyboard

keyboard.wait("p")
print("You pressed p")

It will wait for you to press p and continue the code as it is pressed.

Method #3:

Using the function on_press_key:

import keyboard

keyboard.on_press_key("p", lambda _:print("You pressed p"))

It needs a callback function. I used _ because the keyboard function returns the keyboard event to that function.

Once executed, it will run the function when the key is pressed. You can stop all hooks by running this line:

keyboard.unhook_all()

Method #4:

This method is sort of already answered by user8167727 but I disagree with the code they made. It will be using the function is_pressed but in an other way:

import keyboard

while True:
    if keyboard.is_pressed("p"):
        print("You pressed p")
        break

It will break the loop as p is pressed.

Notes:

• keyboard will read keypresses from the whole OS.
• keyboard requires root on linux

Maybe you'll be able to set the event handlers programmatically, using something like (pseudocode)

sub myhandler(eventsource)
  process(eventsource.value)
end sub

for each cell
  cell.setEventHandler(myHandler)

But i dont know the syntax for achieving this in VB/VBA, or if is even possible.

I was able to connect from SSMS using "(LocalDb)\Projects". That's the way it appears in VS2012 as well.

Language features:

Templates and Generic Code

• Template argument deduction for class templates

  • Like how functions deduce template arguments, now constructors can deduce the template arguments of the class
  • http://wg21.link/p0433r2 http://wg21.link/p0620r0 http://wg21.link/p0512r0

• template <auto>

  • Represents a value of any (non-type template argument) type.

• Non-type template arguments fixes

• template<template<class...>typename bob> struct foo {}

• ( Folding + ... + expressions ) and Revisions

• auto x{8}; is an int

• modernizing using with ... and lists

Lambda

• constexpr lambdas

  • Lambdas are implicitly constexpr if they qualify

• Capturing *this in lambdas

  • [*this]{ std::cout << could << " be " << useful << '\n'; }

Attributes

• [[fallthrough]], [[nodiscard]], [[maybe_unused]] attributes

• [[attributes]] on namespaces and enum { erator[[s]] }

• using in attributes to avoid having to repeat an attribute namespace.

• Compilers are now required to ignore non-standard attributes they don't recognize.

  • The C++14 wording allowed compilers to reject unknown scoped attributes.

Syntax cleanup

• Inline variables

  • Like inline functions
  • Compiler picks where the instance is instantiated
  • Deprecate static constexpr redeclaration, now implicitly inline.

• namespace A::B

• Simple static_assert(expression); with no string

• no throw unless throw(), and throw() is noexcept(true).

Cleaner multi-return and flow control

• Structured bindings

  • Basically, first-class std::tie with auto
  • Example:
    • const auto [it, inserted] = map.insert( {"foo", bar} );
    • Creates variables it and inserted with deduced type from the pair that map::insert returns.
  • Works with tuple/pair-likes & std::arrays and relatively flat structs
  • Actually named structured bindings in standard

• if (init; condition) and switch (init; condition)

  • if (const auto [it, inserted] = map.insert( {"foo", bar} ); inserted)
  • Extends the if(decl) to cases where decl isn't convertible-to-bool sensibly.

• Generalizing range-based for loops

  • Appears to be mostly support for sentinels, or end iterators that are not the same type as begin iterators, which helps with null-terminated loops and the like.

• if constexpr

  • Much requested feature to simplify almost-generic code.

Misc

• Hexadecimal float point literals

• Dynamic memory allocation for over-aligned data

  • Finally!
  • Not in all cases, but distinguishes syntax where you are "just creating something" that was called elision, from "genuine elision".

• Fixed order-of-evaluation for (some) expressions with some modifications

  • Not including function arguments, but function argument evaluation interleaving now banned
  • Makes a bunch of broken code work mostly, and makes .then on future work.

• Direct list-initialization of enums

• Forward progress guarantees (FPG) (also, FPGs for parallel algorithms)

  • I think this is saying "the implementation may not stall threads forever"?

• u8'U', u8'T', u8'F', u8'8' character literals (string already existed)

• "noexcept" in the type system

• __has_include

  • Test if a header file include would be an error
  • makes migrating from experimental to std almost seamless

• Arrays of pointer conversion fixes

  • Deprecates result_of
  • is_invocable<Foo(Args...), R> is "can you call Foo with Args... and get something compatible with R", where R=void is default.
  • invoke_result<Foo, Args...> is std::result_of_t<Foo(Args...)> but apparently less confusing?

Isocpp.org has has an independent list of changes since C++14; it has been partly pillaged.

Naturally TS work continues in parallel, so there are some TS that are not-quite-ripe that will have to wait for the next iteration. The target for the next iteration is C++20 as previously planned, not C++19 as some rumors implied. C++1O has been avoided.

Initial list taken from this reddit post and this reddit post, with links added via googling or from the above isocpp.org page.

Additional entries pillaged from SD-6 feature-test list.

clang's feature list and library feature list are next to be pillaged. This doesn't seem to be reliable, as it is C++1z, not C++17.

these slides had some features missing elsewhere.

While "what was removed" was not asked, here is a short list of a few things ((mostly?) previous deprecated) that are removed in C++17 from C++:

Removed:

• register, keyword reserved for future use
• bool b; ++b;
• trigraphs
  • if you still need them, they are now part of your source file encoding, not part of language
• ios aliases
• auto_ptr, old <functional> stuff, random_shuffle
• allocators in std::function

There were rewordings. I am unsure if these have any impact on code, or if they are just cleanups in the standard:

Papers not yet integrated into above:

• P0505R0 (constexpr chrono)

• P0418R2 (atomic tweaks)

• P0512R0 (template argument deduction tweaks)

• P0490R0 (structured binding tweaks)

• P0513R0 (changes to std::hash)

• P0502R0 (parallel exceptions)

• P0509R1 (updating restrictions on exception handling)

• P0012R1 (make exception specifications be part of the type system)

• P0510R0 (restrictions on variants)

• P0504R0 (tags for optional/variant/any)

• P0497R0 (shared ptr tweaks)

• P0508R0 (structured bindings node handles)

• P0521R0 (shared pointer use count and unique changes?)

Spec changes:

• exception specs and throw expressions

Further reference:

• papers grouped by year; not all accepted

• https://isocpp.org/files/papers/p0636r0.html

  • Should be updated to "Modifications to existing features" here.

Python just passes the filename you give it to the operating system, which opens it. If your operating system supports relative paths like main/2091/data.txt (hint: it does), then that will work fine.

You may find that the easiest way to answer a question like this is to try it and see what happens.

Adding to the answers above, for those who want a quick way to use an external USB device (HDD, flash drive) working inside docker, and not using priviledged mode:

Find the devpath to your device on the host:

sudo fdisk -l

You can recognize your drive by it's capacity quite easily from the list. Copy this path (for the following example it is /dev/sda2).

Disque /dev/sda2 : 554,5 Go, 57151488 octets, 111624 secteurs
Unités : secteur de 1 × 512 = 512 octets
Taille de secteur (logique / physique) : 512 octets / 512 octets
taille d'E/S (minimale / optimale) : 512 octets / 512 octets

Mount this devpath (preferable to /media):

sudo mount <drive path> /media/<mount folder name>

You can then use this either as a param to docker run like:

docker run -it -v /media/<mount folder name>:/media/<mount folder name>

or in docker compose under volumes:

services:
  whatevermyserviceis:
    volumes:
      - /media/<mount folder name>:/media/<mount folder name>

And now when you run and enter your container, you should be able to access the drive inside the container at /media/<mount folder name>

DISCLAIMER:

1. This will probably not work for serial devices such as webcams etc. I have only tested this for USB storage drives.
2. If you need to reconnect and disconnect devices regularly, this method would be annoying, and also would not work unless you reset the mount path and restart the container.
3. I used docker 17.06 + as prescribed in the docs

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

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

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

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

I have found that the problem with IE is that it sniffs the return data and makes up its own mind about what content-type it thinks it has been sent. There are a number of side effect that this causes, such as always openning a saveAs dialog for text files because you are using compression of data trasnferes. The solution is (in php code)......

header('X-Content-Type-Options: nosniff');

If anybody is still looking for this, this is how it worked for me.

You need to find the IP of your machine with respect to the device/emulator you are connected. For Emulators on of the way is by following below steps;

1. Go to VM Virtual box -> select connected device in the list.
2. Select Settings ->Network-> Find out to which network the device is attached. For me it was 'VirtualBox Host-Only Ethernet Adapter #2'.
3. In virtualbox go to Files->Preferences->Network->Host-Only Networks, and find out the IPv4 for the network specified in above step. (By Hovering you will get the info)

Provide this IP to access the localhost from emulator. The Port is same as you have provided while running/publishing your services.

Note #1 : Make sure you have taken care of firewalls and inbound rules.

Note #2 : Please check this IP after you restart your machine. For some reason, even If I provided "Use the following IP" The Host-Only IP got changed.

You can provide a custom Comparator object that ranks elements in the reverse order:

PriorityQueue<Integer> pq = new PriorityQueue<Integer>(defaultSize, new Comparator<Integer>() {
    public int compare(Integer lhs, Integer rhs) {
        if (lhs < rhs) return +1;
        if (lhs.equals(rhs)) return 0;
        return -1;
    }
});

Now, the priority queue will reverse all its comparisons, so you will get the maximum element rather than the minimum element.

Hope this helps!

Updated Answer

If a programmer is interested in only parsing a table from a webpage, they can utilize the pandas method pandas.read_html.

Let's say we want to extract the GDP data table from the website: https://worldpopulationreview.com/countries/countries-by-gdp/#worldCountries

Then following codes does the job perfectly (No need of beautifulsoup and fancy html):

import pandas as pd
import requests

url = "https://worldpopulationreview.com/countries/countries-by-gdp/#worldCountries"

r = requests.get(url)
df_list = pd.read_html(r.text) # this parses all the tables in webpages to a list
df = df_list[0]
df.head()

Output

This worked for me:

• download latest gem at https://rubygems.org/pages/download
• install the gem with gem install --local [path to downloaded gem file]
• update the gems with update_rubygems
• check that you're on the latest gem version with gem --version

Apply the following in your Theme for the Activity in AndroidManifest.xml:

<activity android:name=".DashboardActivity"
        android:theme="@style/AppFullScreenTheme">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

Then Apply the following in your Style in style.xml

<style name="AppFullScreenTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowActionBar">false</item>
    <item name="android:windowFullscreen">true</item>
    <item name="android:windowContentOverlay">@null</item>
</style>

You might wanna use include method in JS.

var sentence = "This is my line";
console.log(sentence.includes("my"));
//returns true if substring is present.

PS: includes is case sensitive.

Try to use jpg and png , also name your image in lowercase. Then drag and drop the image in res/drawable . then go to file and click save all . close eclipse then reopen it again . That is what worked for me .

When you compare update_date >= '2013-05-03' postgres casts values to the same type to compare values. So your '2013-05-03' was casted to '2013-05-03 00:00:00'.

So for update_date = '2013-05-03 14:45:00' your expression will be that:

'2013-05-03 14:45:00' >= '2013-05-03 00:00:00' AND '2013-05-03 14:45:00' <= '2013-05-03 00:00:00'

This is always false

To solve this problem cast update_date to date:

select * from table where update_date::date >= '2013-05-03' AND update_date::date <= '2013-05-03' -> Will return result

You need to type it without the word image.

background: url('/image/btn.png') no-repeat;

Tested both ways and this one works.

Example:

<html>
    <head>
        <style type="text/css">
            .button{
                background: url(/image/btn.png) no-repeat;
                cursor:pointer;
                border: none;
            }
        </style>
    </head>
    <body>
        <input type="button" name="button" value="Search" onclick="showUser()" class="button"/>
        <input type="image" name="button" value="Search" onclick="showUser()" class="button"/>
        <input type="submit" name="button" value="Search" onclick="showUser()" class="button"/>
    </body>
</html>

var myPopup = window.open(...);
myPopup.addEventListener('load', myFunction, false);

If you care about IE, use the following as the second line instead:

myPopup[myPopup.addEventListener ? 'addEventListener' : 'attachEvent'](
  (myPopup.attachEvent ? 'on' : '') + 'load', myFunction, false
);

As you can see, supporting IE is quite cumbersome and should be avoided if possible. I mean, if you need to support IE because of your audience, by all means, do so.

if you are using the MySQLWorkbench you have the option to change the to change the query_alloc_block_size= 16258 and save it.

Step 1. click on the options file at the left side.

Step 2: click on General and select the checkBox of query_alloc_block_size and increase their size. for example change 8129 --> 16258

{
    "data" : [  
        {
            "key1" : "value1",
            "key2" : "value2"   
        },
        {
            "key01" : "value01",
            "key02" : "value02"             
        },
        {
            "key10" : "value10",
            "key20" : "value20"   
        }
    ]
}

You can pass like this. Hope this will help someone.

Try this:

<link href="img/favicon.ico" rel="shortcut icon" type="image/x-icon" />

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

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

You can think of a MySQL "database" as a schema/user in Oracle. If you have the privileges, you can query the DBA_USERS view to see the list of schemas:

SELECT * FROM DBA_USERS;

I implemented all the previous answers and still had one view that did not work correctly.

It turned out the name of the view I was having the problem with was named 'Recent'. Apparently this confused the Internet Explorer browser.

After I changed the view name (in the controller) to a different name (I chose to 'Recent5'), the solutions above started to work.

dat <- dat[-1, ] worked but it killed my dataframe, changing it into another type. Had to instead use dat <- data.frame(dat[-1, ]) but this is possibly a special case as this dataframe initially had only one column.

This is what helped me: Adding specific android platform

What should be done is the following... In my case it was cordova but the same is relevant for ionic, phonegap and other frameworks like these:

1. list all platforms installed for your project: cordova platform list. You'll see something like this:

2. remove the android platform: cordova platform remove android.

3. then add the specific android platform: cordova platform add [email protected].

Good luck! :)

Contains(s2) is many times (in my computer 10 times) faster than IndexOf(s2) because Contains uses StringComparison.Ordinal that is faster than the culture sensitive search that IndexOf does by default (but that may change in .net 4.0 http://davesbox.com/archive/2008/11/12/breaking-changes-to-the-string-class.aspx).

Contains has exactly the same performance as IndexOf(s2,StringComparison.Ordinal) >= 0 in my tests but it's shorter and makes your intent clear.
