Try this instead to only select the visible elements under the tbody:

$('tbody :visible').highlight(myArray[i]);

All this might not help say when you use rails remote form button to simulate click to. I tried to port nice event simulation from prototype here: my snippets. Just did it and it works for me.

"o" format is different for DateTime vs DateTimeOffset :(

DateTime.UtcNow.ToString("o") -> "2016-03-09T03:30:25.1263499Z"

DateTimeOffset.UtcNow.ToString("o") -> "2016-03-09T03:30:46.7775027+00:00"

My final answer is

DateTimeOffset.UtcDateTime.ToString("o")   //for DateTimeOffset type
DateTime.UtcNow.ToString("o")              //for DateTime type

A switch statement can only be used for integral values, not for values of user-defined type. And even if it could, your input operation doesn't work, either.

You might want this:

#include <string>
#include <iostream>


std::string input;

if (!std::getline(std::cin, input)) { /* error, abort! */ }

if (input == "Option 1")
{
    // ... 
}
else if (input == "Option 2")
{ 
   // ...
}

// etc.

A quick note: Assume.assumeTrue(condition) ignores rest of the steps but passes the test. To fail the test, use org.junit.Assert.fail() inside the conditional statement. Works same like Assume.assumeTrue() but fails the test.

// 24-hour time to 12-hour time 
$time_in_12_hour_format  = date("g:i a", strtotime("13:30"));

// 12-hour time to 24-hour time 
$time_in_24_hour_format  = date("H:i", strtotime("1:30 PM"));

It's actually a sensible question. Here's the answer from Excel 2010 help:

"The Workbook object is a member of the Workbooks collection. The Workbooks collection contains all the Workbook objects currently open in Microsoft Excel."

So, since that workbook isn't open - at least I assume it isn't - it can't be set as a workbook object. If it was open you'd just set it like:

Set wbk = workbooks("Master Benchmark Data Sheet.xlsx")

For replace you can use vbCrLf:

Replace(string, vbCrLf, "")

You can also use chr(13)+chr(10).

I seem to remember in some odd cases that chr(10) comes before chr(13).

Just to not leave out the 10.6+ option for enumerating keys and values using blocks...

[dict enumerateKeysAndObjectsUsingBlock:^(id key, id object, BOOL *stop) {
    NSLog(@"%@ = %@", key, object);
}];

If you want the actions to happen concurrently:

[dict enumerateKeysAndObjectsWithOptions:NSEnumerationConcurrent
                              usingBlock:^(id key, id object, BOOL *stop) {
    NSLog(@"%@ = %@", key, object);
}];

Note that setTimeout and setInterval are very different functions:

• setTimeout will execute the code once, after the timeout.
• setInterval will execute the code forever, in intervals of the provided timeout.

Both functions return a timer ID which you can use to abort the timeout. All you have to do is store that value in a variable and use it as argument to clearTimeout(tid) or clearInterval(tid) respectively.

So, depending on what you want to do, you have two valid choices:

// set timeout
var tid = setTimeout(mycode, 2000);
function mycode() {
  // do some stuff...
  tid = setTimeout(mycode, 2000); // repeat myself
}
function abortTimer() { // to be called when you want to stop the timer
  clearTimeout(tid);
}

or

// set interval
var tid = setInterval(mycode, 2000);
function mycode() {
  // do some stuff...
  // no need to recall the function (it's an interval, it'll loop forever)
}
function abortTimer() { // to be called when you want to stop the timer
  clearInterval(tid);
}

Both are very common ways of achieving the same.

Move your javascript into a function and then bind that function to window resize.

$(document).ready(function () {
    updateContainer();
    $(window).resize(function() {
        updateContainer();
    });
});
function updateContainer() {
    var $containerHeight = $(window).height();
    if ($containerHeight <= 818) {
        $('.footer').css({
            position: 'static',
            bottom: 'auto',
            left: 'auto'
        });
    }
    if ($containerHeight > 819) {
        $('.footer').css({
            position: 'absolute',
            bottom: '3px',
            left: '0px'
        });
    }
}

The most important thing to realize is that, using Linq, the query does not get evaluated immediately. It is only run as part of iterating through the resulting IEnumerable<T> in a foreach - that's what all the weird delegates are doing.

So, the first example evaluates the query immediately by calling ToList and putting the query results in a list.
The second example returns an IEnumerable<T> that contains all the information needed to run the query later on.

In terms of performance, the answer is it depends. If you need the results to be evaluated at once (say, you're mutating the structures you're querying later on, or if you don't want the iteration over the IEnumerable<T> to take a long time) use a list. Else use an IEnumerable<T>. The default should be to use the on-demand evaluation in the second example, as that generally uses less memory, unless there is a specific reason to store the results in a list.

Using urllib3

To do that, you will need to manually encode query parameters in the URL.

>>> import urllib3
>>> http = urllib3.PoolManager()
>>> from urllib.parse import urlencode
>>> encoded_args = urlencode({"name":"Zion","salary":"1123","age":"23"})
>>> url = 'http://dummy.restapiexample.com/api/v1/update/15410' + encoded_args
>>> r = http.request('PUT', url)
>>> import json
>>> json.loads(r.data.decode('utf-8'))
{'status': 'success', 'data': [], 'message': 'Successfully! Record has been updated.'}

Using requests

>>> import requests
>>> r = requests.put('https://httpbin.org/put', data = {'key':'value'})
>>> r.status_code
200

Processing the ASP.NET web-form takes place in stages. At each state various events are raised. If you are interested to plug your code into the processing flow (on server side) then you have to handle appropriate page event.

raw_input is your helper here. From documentation -

If the prompt argument is present, it is written to standard output without a trailing newline. The function then reads a line from input, converts it to a string (stripping a trailing newline), and returns that. When EOF is read, EOFError is raised.

So your code will basically look like this.

num_array = list()
num = raw_input("Enter how many elements you want:")
print 'Enter numbers in array: '
for i in range(int(num)):
    n = raw_input("num :")
    num_array.append(int(n))
print 'ARRAY: ',num_array

P.S: I have typed all this free hand. Syntax might be wrong but the methodology is correct. Also one thing to note is that, raw_input does not do any type checking, so you need to be careful...

Returning falsy value in the render() function will render nothing. So you can just do

 render() {
    let finalClasses = "" + (this.state.classes || "");
    return !isTimeout && <div>{this.props.children}</div>;
  }

import requests
url = "https://www.googleapis.com/qpxExpress/v1/trips/search?key=mykeyhere"
data = requests.get(url).json

maybe?

if you are trying to send a file

files = {'request_file': open('request.json', 'rb')}
r = requests.post(url, files=files)
print r.text, print r.json

ahh thanks @LukasGraf now i better understand what his original code is doing

import requests,json
url = "https://www.googleapis.com/qpxExpress/v1/trips/search?key=mykeyhere"
my_json_data = json.load(open("request.json"))
req = requests.post(url,data=my_json_data)
print req.text
print 
print req.json # maybe? 

You can use this:

var isEmpty = function(obj) {
  return Object.keys(obj).length === 0;
}

or this:

function isEmpty(obj) {
  return !Object.keys(obj).length > 0;
}

You can also use this:

function isEmpty(obj) {
  for(var prop in obj) {
    if(obj.hasOwnProperty(prop))
      return false;
  }

  return true;
}

If using underscore or jQuery, you can use their isEmpty or isEmptyObject calls.

As the documentation states ^[docs],

In user defined base classes, abstract methods should raise this exception when they require derived classes to override the method, or while the class is being developed to indicate that the real implementation still needs to be added.

Note that although the main stated use case this error is the indication of abstract methods that should be implemented on inherited classes, you can use it anyhow you'd like, like for indication of a TODO marker.

This is how Adding new column to Table

ALTER TABLE [tableName]
ADD ColumnName Datatype

E.g

ALTER TABLE [Emp]
ADD Sr_No Int

And If you want to make it auto incremented

ALTER TABLE [Emp]
ADD Sr_No Int IDENTITY(1,1) NOT NULL

yourLabel.intrinsicContentSize.width for Objective-C / Swift

As i have implemented, and it is working fine. you just need to add column width using matColumnDef="description"

for example :

<mat-table #table [dataSource]="dataSource" matSortDisableClear>
    <ng-container matColumnDef="productId">
        <mat-header-cell *matHeaderCellDef>product ID</mat-header-cell>
        <mat-cell *matCellDef="let product">{{product.id}}</mat-cell>
    </ng-container>
    <ng-container matColumnDef="productName">
        <mat-header-cell *matHeaderCellDef>Name</mat-header-cell>
        <mat-cell *matCellDef="let product">{{product.name}}</mat-cell>
    </ng-container>
    <ng-container matColumnDef="actions">
        <mat-header-cell *matHeaderCellDef>Actions</mat-header-cell>
        <mat-cell *matCellDef="let product">
            <button (click)="view(product)">
                <mat-icon>visibility</mat-icon>
            </button>
        </mat-cell>
    </ng-container>
    <mat-header-row *matHeaderRowDef="displayedColumns"></mat-header-row>
    <mat-row *matRowDef="let row; columns: displayedColumns"></mat-row>
</mat-table>

here matColumnDef is productId, productName and action

now we apply width by matColumnDef

styling

.mat-column-productId {
    flex: 0 0 10%;
}
.mat-column-productName {
    flex: 0 0 50%;
}

and remaining width is equally allocated to other columns

Arel is your friend:

User.where(User.arel_table[:id].gt(200))

OPTIMIZE TABLE works fine with InnoDB engine according to the official support article : http://dev.mysql.com/doc/refman/5.5/en/optimize-table.html

You'll notice that optimize InnoDB tables will rebuild table structure and update index statistics (something like ALTER TABLE).

Keep in mind that this message could be an informational mention only and the very important information is the status of your query : just OK !

mysql> OPTIMIZE TABLE foo;
+----------+----------+----------+-------------------------------------------------------------------+
| Table    | Op       | Msg_type | Msg_text                                                          |
+----------+----------+----------+-------------------------------------------------------------------+
| test.foo | optimize | note     | Table does not support optimize, doing recreate + analyze instead |

+----------+----------+----------+-------------------------------------------------------------------+

As simple as this-

figure, plot(yourfigure);

Put the h1 and h2 in a container with an id of container then:

#container {
    display: flex;
    justify-content: space-beteen;
}

The error you are getting seems to be because there is no swap module on the server, you should install swap on the server then run the script again

Haskell

foldl (+) 0 [1,2,3,4,5]

Python

reduce(lambda a,b: a+b, [1,2,3,4,5], 0)

Obviously, that is a trivial example to illustrate a point. In Python you would just do sum([1,2,3,4,5]) and even Haskell purists would generally prefer sum [1,2,3,4,5].

For non-trivial scenarios when there is no obvious convenience function, the idiomatic pythonic approach is to explicitly write out the for loop and use mutable variable assignment instead of using reduce or a fold.

That is not at all the functional style, but that is the "pythonic" way. Python is not designed for functional purists. See how Python favors exceptions for flow control to see how non-functional idiomatic python is.

My reputation being too small to comment an answer, here is my feedback concerning roquen answer (using settings on xmlwriter to force the stream to close): it works perfectly and it made me save a lot of time. roquen's example requires some adjustment, here is the code that works on .NET framework 4.8 :

    XmlWriterSettings settings = new XmlWriterSettings();
    settings.CloseOutput = true;
    writer = XmlWriter.Create(stream, settings);

With the newer Web Api 2 it has become easier to have multiple get methods.

If the parameter passed to the GET methods are different enough for the attribute routing system to distinguish their types as is the case with ints and Guids you can specify the expected type in the [Route...] attribute

For example -

[RoutePrefix("api/values")]
public class ValuesController : ApiController
{

    // GET api/values/7
    [Route("{id:int}")]
    public string Get(int id)
    {
       return $"You entered an int - {id}";
    }

    // GET api/values/AAC1FB7B-978B-4C39-A90D-271A031BFE5D
    [Route("{id:Guid}")]
    public string Get(Guid id)
    {
       return $"You entered a GUID - {id}";
    }
} 

For more details about this approach, see here http://nodogmablog.bryanhogan.net/2017/02/web-api-2-controller-with-multiple-get-methods-part-2/

Another options is to give the GET methods different routes.

    [RoutePrefix("api/values")]
    public class ValuesController : ApiController
    {
        public string Get()
        {
            return "simple get";
        }

        [Route("geta")]
        public string GetA()
        {
            return "A";
        }

        [Route("getb")]
        public string GetB()
        {
            return "B";
        }
   }

See here for more details - http://nodogmablog.bryanhogan.net/2016/10/web-api-2-controller-with-multiple-get-methods/

On the one hand, the title is helpful as a tooltip when moving the mouse over the element. This could be solved with CSS-> element::after. But it is much more important as an aid for visually impaired people (topic handicap-free website). And for this it MUST be included as an attribute in the HTML element. Everything else is junk, botch, idiot stuff ...!

float(item) do the right thing: it converts its argument to float and and return it, but it doesn't change argument in-place. A simple fix for your code is:

new_list = []
for item in list:
    new_list.append(float(item))

The same code can written shorter using list comprehension: new_list = [float(i) for i in list]

To change list in-place:

for index, item in enumerate(list):
    list[index] = float(item)

BTW, avoid using list for your variables, since it masquerades built-in function with the same name.

'^(part1|part2|part1,part2)$'

does it work?

In your CSS Style tag put this:

body {
  background: url('yourgif.gif') no-repeat center center fixed;
  background-size: cover;
}

CGRect buttonFrame = CGRectMake( 10, 80, 100, 30 );
        UIButton *button = [[UIButton alloc] initWithFrame: buttonFrame];
        [button setTitle: @"My Button" forState: UIControlStateNormal];
        [button addTarget:self action:@selector(btnSelected:) forControlEvents:UIControlEventTouchUpInside];
        [button setTitleColor: [UIColor redColor] forState: UIControlStateNormal];
[view addSubview:button];

Why should it be so hard? It's just UI logic. Use a dedicated action to set notification data:

dispatch({ notificationData: { message: 'message', expire: +new Date() + 5*1000 } })

and a dedicated component to display it:

const Notifications = ({ notificationData }) => {
    if(notificationData.expire > this.state.currentTime) {
      return <div>{notificationData.message}</div>
    } else return null;
}

In this case the questions should be "how do you clean up old state?", "how to notify a component that time has changed"

You can implement some TIMEOUT action which is dispatched on setTimeout from a component.

Maybe it's just fine to clean it whenever a new notification is shown.

Anyway, there should be some setTimeout somewhere, right? Why not to do it in a component

setTimeout(() => this.setState({ currentTime: +new Date()}), 
           this.props.notificationData.expire-(+new Date()) )

The motivation is that the "notification fade out" functionality is really a UI concern. So it simplifies testing for your business logic.

It doesn't seem to make sense to test how it's implemented. It only makes sense to verify when the notification should time out. Thus less code to stub, faster tests, cleaner code.

The tool NDepend is quoted as Quality Metric Tools but it is pretty much also a Code violation detection tool. Disclaimer: I am one of the developers of the tool

With NDepend, one can write Code Rule over LINQ Queries (what we call CQLinq). More than 200 CQLinq code rules are proposed by default. The strength of CQLinq is that it is straightforward to write a code rule, and get immediately results. Facilities are proposed to browse matched code elements. For example:

Beside that, NDepend comes with many others static analysis like features. These include:

• Smart Technical Debt Estimation
• Dependency Graph
• Dependency Matrix
• Code Diff capabilities
• NDepend.API that lets write you own static analysis tool. With NDepend.APi we even developed a tool to detect code duplicate (details in this blog post: An Original Algorithm to Find .NET Code Duplicate).

From stringr library you could try this:

2. Remove fill blank

keydown with event.key === "Backspace" or "Delete"

More recent and much cleaner: use event.key. No more arbitrary number codes!

input.addEventListener('keydown', function(event) {
    const key = event.key; // const {key} = event; ES6+
    if (key === "Backspace" || key === "Delete") {
        return false;
    }
});

Modern style:

input.addEventListener('keydown', ({key}) => {
    if (["Backspace", "Delete"].includes(key)) {
        return false
    }
})

With live streaming i was facing the same issue. and my fix is this. From html video TAG make sure to remove "autoplay" and use this below code to play.

            hls.attachMedia(video);
            hls.on(Hls.Events.MANIFEST_PARSED, function () {
                video.play();

Nice answer by Alex and Sameer, but maybe just additional info on why is necessary to put

public $timestamps = false;

Timestamps are nicely explained on official Laravel page:

By default, Eloquent expects created_at and updated_at columns to exist on your >tables. If you do not wish to have these columns automatically managed by >Eloquent, set the $timestamps property on your model to false.

Craig Stuntz has written an extensive (in my opinion) blog post on troubleshooting this exact error message, I personally would start there.

The following res: (resource) references need to point to your model.

<add name="Entities" connectionString="metadata=
    res://*/Models.WraithNath.co.uk.csdl|
    res://*/Models.WraithNath.co.uk.ssdl|
    res://*/Models.WraithNath.co.uk.msl;

Make sure each one has the name of your .edmx file after the "*/", with the "edmx" changed to the extension for that res (.csdl, .ssdl, or .msl).

It also may help to specify the assembly rather than using "//*/".

Worst case, you can check everything (a bit slower but should always find the resource) by using

<add name="Entities" connectionString="metadata=
        res://*/;provider= <!-- ... -->

I had the same problem. My customer ordered me Python 3.4 script that updates XLS (not XLSX) Excel files.

The 1st package xlrd was installed by "pip install" without problems in my Python home.

The 2nd one xlwt needed to say "pip install xlwt-future" to be compatible.

The 3rd one xlutils has no support for Python 3, but I adapted it a little bit and now it works at least for dummy script:

#!C:\Python343\python
from xlutils.copy import copy # http://pypi.python.org/pypi/xlutils
from xlrd import open_workbook # http://pypi.python.org/pypi/xlrd
from xlwt import easyxf # http://pypi.python.org/pypi/xlwt

file_path = 'C:\Dev\Test_upd.xls'
rb = open_workbook('C:\Dev\Test.xls',formatting_info=True)
r_sheet = rb.sheet_by_index(0) # read only copy to introspect the file
wb = copy(rb) # a writable copy (I can't read values out of this, only write to it)
w_sheet = wb.get_sheet(0) # the sheet to write to within the writable copy
w_sheet.write(1, 1, 'Value')
wb.save(file_path)

I attached the file here: http://ifolder.su/43507580

Write to [email protected] if it got expired.

P.S.: Some functions are not called in the dummy example, so maybe they will need for an adaptation also. Who wants to do it, fix exceptions one-by-one with a google help. It's not a very difficult task, because the package code is small...

If the above solution didn't work for you, you can use import { withRouter } from 'react-router-dom';

Using this you can export your child class as -

class MyApp extends Component{
    // your code
}

export default withRouter(MyApp);

And your class with Router -

// your code
<Router>
      ...
      <Route path="/myapp" component={MyApp} />
      // or if you are sending additional fields
      <Route path="/myapp" component={() =><MyApp process={...} />} />
<Router>

a=1;
b=2;

x=3;
y=4;

answer = a > b ? x : y;

answer=4 since the condition is false it takes y value.

A question mark (?)
. The value to use if the condition is true

A colon (:)
. The value to use if the condition is false

Here is a complete list of steps - you may not need steps 1-3 but am including them for completeness:-

1. Download VS Code and Apache Maven and install both.
2. Install the Visual Studio extension pack for Java - e.g. by pasting this URL into a web browser: vscode:extension/vscjava.vscode-java-pack and then clicking on the green Install button after it opens in VS Code.
3. NOTE: See the comment from ADTC for an "Easier GUI version of step 3...(Skip step 4)." If necessary, the Maven quick start archetype could be used to generate a new Maven project in an appropriate local folder: mvn archetype:generate -DgroupId=com.companyname.appname-DartifactId=appname-DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false. This will create an appname folder with Maven's Standard Directory Layout (i.e. src/main/java/com/companyname/appname and src/main/test/com/companyname/appname to begin with and a sample "Hello World!" Java file named appname.java and associated unit test named appnameTest.java).*
4. Open the Maven project folder in VS Code via File menu -> Open Folder... and select the appname folder.
5. Open the Command Palette (via the View menu or by right-clicking) and type in and select Tasks: Configure task then select Create tasks.json from template.

6. Choose maven ("Executes common Maven commands"). This creates a tasks.json file with "verify" and "test" tasks. More can be added corresponding to other Maven Build Lifecycle phases. To specifically address your requirement for classes to be built without a JAR file, a "compile" task would need to be added as follows:

   {
       "label": "compile",
       "type": "shell",
       "command": "mvn -B compile",
       "group": "build"
   },
   

7. Save the above changes and then open the Command Palette and select "Tasks: Run Build Task" then pick "compile" and then "Continue without scanning the task output". This invokes Maven, which creates a target folder at the same level as the src folder with the compiled class files in the target\classes folder.

Addendum: How to run/debug a class

Following a question in the comments, here are some steps for running/debugging:-

1. Show the Debug view if it is not already shown (via View menu - Debug or CtrlShiftD).
2. Click on the green arrow in the Debug view and select "Java".
3. Assuming it hasn't already been created, a message "launch.json is needed to start the debugger. Do you want to create it now?" will appear - select "Yes" and then select "Java" again.
4. Enter the fully qualified name of the main class (e.g. com.companyname.appname.App) in the value for "mainClass" and save the file.
5. Click on the green arrow in the Debug view again.

Something better would be:

<Grid Width="Your-specified-value" >
    <ScrollViewer>
         <TextBlock Width="Auto" TextWrapping="Wrap" />
    </ScrollViewer>
</Grid>

This makes sure that the text in your textblock does not overflow and overlap the elements below the textblock as may be the case if you do not use the grid. That happened to me when I tried other solutions even though the textblock was already in a grid with other elements. Keep in mind that the width of the textblock should be Auto and you should specify the desired with in the Grid element. I did this in my code and it works beautifully. HTH.

You are implementing LocationListener in your activity MainActivity. The call for concurrent location updates will therefor be like this:

mLocationClient.requestLocationUpdates(mLocationRequest, this);

Be sure that the LocationListener you're implementing is from the google api, that is import this:

import com.google.android.gms.location.LocationListener;

and not this:

import android.location.LocationListener;

and it should work just fine.

It's also important that the LocationClient really is connected before you do this. I suggest you don't call it in the onCreate or onStart methods, but in onResume. It is all explained quite well in the tutorial for Google Location Api: https://developer.android.com/training/location/index.html

I've ran into the same problem recently. After finding the correct path to the pyuic4 file using the file finder I've ran:

C:\Users\ricckli.qgis2\python\plugins\qgis2leaf>C:\OSGeo4W64\bin\pyuic4 -o ui_q gis2leaf.py ui_qgis2leaf.ui

As you can see my ui file was placed in this folder...

QT Creator was installed separately and the pyuic4 file was placed there with the OSGEO4W installer

How about either of:

>>> df
         date  duration user_id
0  2013-04-01        30    0001
1  2013-04-01        15    0001
2  2013-04-01        20    0002
3  2013-04-02        15    0002
4  2013-04-02        30    0002
>>> df.groupby("date").agg({"duration": np.sum, "user_id": pd.Series.nunique})
            duration  user_id
date                         
2013-04-01        65        2
2013-04-02        45        1
>>> df.groupby("date").agg({"duration": np.sum, "user_id": lambda x: x.nunique()})
            duration  user_id
date                         
2013-04-01        65        2
2013-04-02        45        1

Using .trigger("chosen:updated"); you can update the options list after appending.

Updating Chosen Dynamically: If you need to update the options in your select field and want Chosen to pick up the changes, you'll need to trigger the "chosen:updated" event on the field. Chosen will re-build itself based on the updated content.

Your code:

$("#refreshgallery").click(function(){
        $('#picturegallery').empty(); //remove all child nodes
        var newOption = $('<option value="1">test</option>');
        $('#picturegallery').append(newOption);
        $('#picturegallery').trigger("chosen:updated");
    });

I was having a similar issue. In my case, looking at the CSS i found a position: initial.

After some research, i found that mobile IE browser doesn't supports it.

I simply put a position: relative instead and everything worked fine.

Short answer: No.

Long answer:

First, without an href attribute, it will not be a link. If it isn't a link then it wont be keyboard (or breath switch, or various other not pointer based input device) accessible (unless you use HTML 5 features of tabindex which are not universally supported). It is very rare that it is appropriate for a control to not have keyboard access.

Second. You should have an alternative for when the JavaScript does not run (because it was slow to load from the server, an Internet connection was dropped (e.g. mobile signal on a moving train), JS is turned off, etc, etc).

Make use of progressive enhancement by unobtrusive JS.

try this one out.

<label for="user">user</label>
<input type="text" name="user" 
onfocus="if(this.value==this.defaultValue)this.value=''"    
onblur="if(this.value=='')this.value=this.defaultValue" 
value="username" maxlength="19" />

hope this helps.

I had a similar issue where I couldn't connect to a database and tried the recommendations here.

At the end of the day this is what worked for me:

Used the SQL Server Configuration Manager tool to enable the TCP/IP and/or the Named Pipes protocols on the SQL Server client computer.

1. Click Start, point to All Programs, and click SQL Server Configuration Manager.
2. Click to expand SQL Server Network Configuration and then click Client Protocols.
3. Right-click the TCP/IP protocol and then click Enable.
4. Right-click the Named Pipes protocol and then click Enable.
5. Restart the SQL server service if prompted to do so.

I am still not sure why or when this was disabled.

As you went through the tutorial you must have come across the section on migration, as this was one of the major changes in Django 1.7

Prior to Django 1.7, the syncdb command never made any change that had a chance to destroy data currently in the database. This meant that if you did syncdb for a model, then added a new row to the model (a new column, effectively), syncdb would not affect that change in the database.

So either you dropped that table by hand and then ran syncdb again (to recreate it from scratch, losing any data), or you manually entered the correct statements at the database to add only that column.

Then a project came along called south which implemented migrations. This meant that there was a way to migrate forward (and reverse, undo) any changes to the database and preserve the integrity of data.

In Django 1.7, the functionality of south was integrated directly into Django. When working with migrations, the process is a bit different.

1. Make changes to models.py (as normal).
2. Create a migration. This generates code to go from the current state to the next state of your model. This is done with the makemigrations command. This command is smart enough to detect what has changed and will create a script to effect that change to your database.
3. Next, you apply that migration with migrate. This command applies all migrations in order.

So your normal syncdb is now a two-step process, python manage.py makemigrations followed by python manage.py migrate.

Now, on to your specific problem:

class Snippet(models.Model):
    owner = models.ForeignKey('auth.User', related_name='snippets')
    highlighted = models.TextField()
    created = models.DateTimeField(auto_now_add=True)
    title = models.CharField(max_length=100, blank=True, default='')
    code = models.TextField()
    linenos = models.BooleanField(default=False)
    language = models.CharField(choices=LANGUAGE_CHOICES,
                                            default='python',
                                            max_length=100)
    style = models.CharField(choices=STYLE_CHOICES,
                                     default='friendly',
                                     max_length=100)

In this model, you have two fields highlighted and code that is required (they cannot be null).

Had you added these fields from the start, there wouldn't be a problem because the table has no existing rows?

However, if the table has already been created and you add a field that cannot be null, you have to define a default value to provide for any existing rows - otherwise, the database will not accept your changes because they would violate the data integrity constraints.

This is what the command is prompting you about. You can tell Django to apply a default during migration, or you can give it a "blank" default highlighted = models.TextField(default='') in the model itself.

For XAMPP on MACOS or Linux, remove the semicolon in php.ini file after extension=curl.so

For windows environment:

"scripts": {
    "clean": "rmdir /s /q node_modules",
    ...
}

Fancy indexing requires you to provide all indices for each dimension. You are providing 3 indices for the first one, and only 2 for the second one, hence the error. You want to do something like this:

>>> a[[[0, 0], [1, 1], [3, 3]], [[0,2], [0,2], [0, 2]]]
array([[ 0,  2],
       [ 4,  6],
       [12, 14]])

That is of course a pain to write, so you can let broadcasting help you:

>>> a[[[0], [1], [3]], [0, 2]]
array([[ 0,  2],
       [ 4,  6],
       [12, 14]])

This is much simpler to do if you index with arrays, not lists:

>>> row_idx = np.array([0, 1, 3])
>>> col_idx = np.array([0, 2])
>>> a[row_idx[:, None], col_idx]
array([[ 0,  2],
       [ 4,  6],
       [12, 14]])

Their is a tool called indent. You can download it with apt-get install indent, then run indent my_program.c.

Use the Below Code for that

UPDATE Table1 SET Column1 = LTRIM(RTRIM(REPLACE(REPLACE(REPLACE(Column1, CHAR(9), ''), CHAR(10), ''), CHAR(13), '')))`

You should \usepackage{longtable}.

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

You can list the tags on remote repository with ls-remote, and then check if it's there. Supposing the remote reference name is origin in the following.

git ls-remote --tags origin

And you can list tags local with tag.

git tag

You can compare the results manually or in script.

I was looking into this issue a bit for my own purposes; I had a slice of structs (including some pointers) and I wanted to make sure I got it right; ended up on this thread, and wanted to share my results.

To practice, I did a little go playground: https://play.golang.org/p/9i4gPx3lnY

which evals to this:

package main

import "fmt"

type Blah struct {
    babyKitten int
    kittenSays *string
}

func main() {
    meow := "meow"
    Blahs := []Blah{}
    fmt.Printf("Blahs: %v\n", Blahs)
    Blahs = append(Blahs, Blah{1, &meow})
    fmt.Printf("Blahs: %v\n", Blahs)
    Blahs = append(Blahs, Blah{2, &meow})
    fmt.Printf("Blahs: %v\n", Blahs)
    //fmt.Printf("kittenSays: %v\n", *Blahs[0].kittenSays)
    Blahs = nil
    meow2 := "nyan"
    fmt.Printf("Blahs: %v\n", Blahs)
    Blahs = append(Blahs, Blah{1, &meow2})
    fmt.Printf("Blahs: %v\n", Blahs)
    fmt.Printf("kittenSays: %v\n", *Blahs[0].kittenSays)
}

Running that code as-is will show the same memory address for both "meow" and "meow2" variables as being the same:

Blahs: []
Blahs: [{1 0x1030e0c0}]
Blahs: [{1 0x1030e0c0} {2 0x1030e0c0}]
Blahs: []
Blahs: [{1 0x1030e0f0}]
kittenSays: nyan

which I think confirms that the struct is garbage collected. Oddly enough, uncommenting the commented print line, will yield different memory addresses for the meows:

Blahs: []
Blahs: [{1 0x1030e0c0}]
Blahs: [{1 0x1030e0c0} {2 0x1030e0c0}]
kittenSays: meow
Blahs: []
Blahs: [{1 0x1030e0f8}]
kittenSays: nyan

I think this may be due to the print being deferred in some way (?), but interesting illustration of some memory mgmt behavior, and one more vote for:

[]MyStruct = nil

When you create a virtual device from Android Studio pay attention to the Play Store Column in the device table. The images with the play store icon have google play pre-installed.

?? In system images that come with google play root is not available.

After you've created the AVD you'll also be able to see from the Android Studio AVD Manager which of your images have google play installed:

This is not as easy as it seems, some core library functions don't work when only str is overwritten (checked with Python 2.7), see this thread for examples How to make a class JSON serializable Also, try this

import json

class A(unicode):
    def __str__(self):
        return 'a'
    def __unicode__(self):
        return u'a'
    def __repr__(self):
        return 'a'

a = A()
json.dumps(a)

produces

'""'

and not

'"a"'

as would be expected.

EDIT: answering mchicago's comment:

unicode does not have any attributes -- it is an immutable string, the value of which is hidden and not available from high-level Python code. The json module uses re for generating the string representation which seems to have access to this internal attribute. Here's a simple example to justify this:

b = A('b') print b

produces

'a'

while

json.dumps({'b': b})

produces

{"b": "b"}

so you see that the internal representation is used by some native libraries, probably for performance reasons.

I was having similar problem and

var dataObj = JSON.parse(data);

console.log(dataObj[0].category); //will return Damskie
console.log(dataObj[1].category); //will return Meskie

This solved my problem. Thanks Selvakumar Arumugam

I had the same issue and found a unique solution. This is not best practice, but it may prove simple/helpful for someone. Just use jquery on the id or class or your select tag and you then have access to both the text and the value in the change function. In my case I'm passing in option values via sails/ejs:

    <select id="projectSelector" class="form-control" ng-model="ticket.project.id" ng-change="projectChange(ticket)">
      <% _.each(projects, function(project) { %>
        <option value="<%= project.id %>"><%= project.title %></option>
        <% }) %>
    </select>

Then in my Angular controller my ng-change function looks like this:

    $scope.projectChange = function($scope) {
         $scope.project.title=$("#projectSelector option:selected").text();
     };

public DataTable ConvertToDataTable<T>(IList<T> data)
{
    PropertyDescriptorCollection properties =
        TypeDescriptor.GetProperties(typeof(T));

    DataTable table = new DataTable();

    foreach (PropertyDescriptor prop in properties)
            table.Columns.Add(prop.Name, Nullable.GetUnderlyingType(prop.PropertyType) ?? prop.PropertyType);

    foreach (T item in data)
    {
        DataRow row = table.NewRow();
        foreach (PropertyDescriptor prop in properties)
        {
           row[prop.Name] = prop.GetValue(item) ?? DBNull.Value;
        }
        table.Rows.Add(row);
    }
    return table;
}

It creates a hidden input on the form for the field (from your model) that you pass it.

It is useful for fields in your Model/ViewModel that you need to persist on the page and have passed back when another call is made but shouldn't be seen by the user.

Consider the following ViewModel class:

public class ViewModel
{
    public string Value { get; set; }
    public int Id { get; set; }
}

Now you want the edit page to store the ID but have it not be seen:

<% using(Html.BeginForm() { %>
    <%= Html.HiddenFor(model.Id) %><br />
    <%= Html.TextBoxFor(model.Value) %>
<% } %>

This results in the equivalent of the following HTML:

<form name="form1">
    <input type="hidden" name="Id">2</input>
    <input type="text" name="Value" value="Some Text" />
</form>

SELECT * from SOME_TABLE where NAME like '%[^A-Z]%'

Or some other expression instead of A-Z

Even if we interchange @Component or @Repository or @service

It will behave the same , but one aspect is that they wont be able to catch some specific exception related to DAO instead of Repository if we use component or @ service

• XQuery Against the xml Data Type
• General XQuery Use Cases
• XQueries Involving Hierarchy

• XQueries Involving Order

• Anything in Michael Rys blog

Update

My recomendation would be to shred the XML into relations and do searches and joins on the resulted relation, in a set oriented fashion, rather than the procedural fashion of searching specific nodes in the XML. Here is a simple XML query that shreds out the nodes and attributes of interest:

select x.value(N'../../../../@stepId', N'int') as StepID
  , x.value(N'../../@id', N'int') as ComponentID
  , x.value(N'@nom',N'nvarchar(100)') as Nom
  , x.value(N'@valeur', N'nvarchar(100)') as Valeur
from @x.nodes(N'/xml/box/components/component/variables/variable') t(x)

However, if you must use an XPath that retrieves exactly the value of interest:

select x.value(N'@valeur', N'nvarchar(100)') as Valeur
from @x.nodes(N'/xml/box[@stepId=sql:variable("@stepID")]/
    components/component[@id = sql:variable("@componentID")]/
       variables/variable[@nom="Enabled"]') t(x)

If the stepID and component ID are columns, not variables, the you should use sql:column() instead of sql:variable in the XPath filters. See Binding Relational Data Inside XML Data.

And finaly if all you need is to check for existance you can use the exist() XML method:

select @x.exist(
  N'/xml/box[@stepId=sql:variable("@stepID")]/
    components/component[@id = sql:variable("@componentID")]/
      variables/variable[@nom="Enabled" and @valeur="Yes"]') 

For all those who lost heart trying to set a default DATETIME value in MySQL, I know exactly how you feel/felt. So here is is:

ALTER TABLE  `table_name` CHANGE `column_name` DATETIME NOT NULL DEFAULT 0

Carefully observe that I haven't added single quotes/double quotes around the 0

I'm literally jumping after solving this one :D

Doing the expicit casting to the "int" solves the problem in my case. I had the same issue. So:

int count = (int)[myColors count];

ADD and COPY both have same functionality of copying files and directories from source to destination but ADD has extra of file extraction and URL file extraction functionality. The best practice is to use COPY in only copy operation only avoid ADD is many areas. The link will explain it with some simple examples difference between COPY and ADD in dockerfile

Use sessions

On your search.jsp

Put your scard in sessions using session.setAttribute("scard","scard")

//the 1st variable is the string name that you will retrieve in ur next page,and the 2nd variable is the its value,i.e the scard value.

And in your next page you retrieve it using session.getAttribute("scard")

UPDATE

<input type="text" value="<%=session.getAttribute("scard")%>"/>

if (!System.IO.File.Exists(filePath))
    return SomeHelper.EmptyImageResult(); // preventing JSON GET/POST exception
else
    return new FilePathResult(filePath, contentType);

SomeHelper.EmptyImageResult() should return FileResult with existing image (1x1 transparent, for example).

This is easiest way if you have files stored on local drive. If files are byte[] or stream - then use FileContentResult or FileStreamResult as Dylan suggested.

I am not sure if anyone would take this much pain to test GET and POST calls. I took Python Flask module and wrote a function that does something similar to what @Robert shared.

from flask import Flask, request
app = Flask(__name__)

@app.route('/method', methods=['GET', 'POST'])
@app.route('/method/<wish>', methods=['GET', 'POST'])
def method_used(wish=None):
    if request.method == 'GET':
        if wish:
            if wish in dir(request):
                ans = None
                s = "ans = str(request.%s)" % wish
                exec s
                return ans
            else:
                return 'This wish is not available. The following are the available wishes: %s' % [method for method in dir(request) if '_' not in method]
        else:
            return 'This is just a GET method'
    else:
        return "You are using POST"

When I run this, this follows:

C:\Python27\python.exe E:/Arindam/Projects/Flask_Practice/first.py
 * Restarting with stat
 * Debugger is active!
 * Debugger PIN: 581-155-269

Now lets try some calls. I am using the browser.

http://127.0.0.1:5000/method

This is just a GET method

use:

std::vector <Acard> playerHand;

everywhere qualify it by std::

or do:

using std::vector;

in your cpp file.

You have to do this because vector is defined in the std namespace and you do not tell your program to find it in std namespace, you need to tell that.

I had this issue myself, and I wanted to both be able to set the width, and have it update on rotate and allow the user to scale and zoom the page (the current answer provides the first but prevents the later as a side-effect).. so I came up with a fix that keeps the view width correct for the orientation, but still allows for zooming, though it is not super straight forward.

First, add the following Javascript to the webpage you are displaying:

 <script type='text/javascript'>
 function setViewPortWidth(width) {
  var metatags = document.getElementsByTagName('meta');
  for(cnt = 0; cnt < metatags.length; cnt++) { 
   var element = metatags[cnt];
   if(element.getAttribute('name') == 'viewport') {

    element.setAttribute('content','width = '+width+'; maximum-scale = 5; user-scalable = yes');
    document.body.style['max-width'] = width+'px';
   }
  }
 }
 </script>

Then in your - (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation method, add:

float availableWidth = [EmailVC webViewWidth];
NSString *stringJS;

stringJS = [NSString stringWithFormat:@"document.body.offsetWidth"];
float documentWidth = [[_webView stringByEvaluatingJavaScriptFromString:stringJS] floatValue];

if(documentWidth > availableWidth) return; // Don't perform if the document width is larger then available (allow auto-scale)

// Function setViewPortWidth defined in EmailBodyProtocolHandler prepend
stringJS = [NSString stringWithFormat:@"setViewPortWidth(%f);",availableWidth];
[_webView stringByEvaluatingJavaScriptFromString:stringJS];

Additional Tweaking can be done by modifying more of the viewportal content settings:

http://www.htmlgoodies.com/beyond/webmaster/toolbox/article.php/3889591/Detect-and-Set-the-iPhone--iPads-Viewport-Orientation-Using-JavaScript-CSS-and-Meta-Tags.htm

Also, I understand you can put a JS listener for onresize or something like to trigger the rescaling, but this worked for me as I'm doing it from Cocoa Touch UI frameworks.

Hope this helps someone :)

I was having a similar issue but none of these fixes worked. The problem was that my button was not yet on the page. The fix for this ended up being going from this:

//Bad code.
var btn = document.createElement('button');
btn.onClick = function() {  console.log("hey");  }

to this:

//Working Code.  I don't like it, but it works. 
var btn = document.createElement('button');
var wrapper = document.createElement('div');
wrapper.appendChild(btn);

document.body.appendChild(wrapper);
var buttons = wrapper.getElementsByTagName("BUTTON");
buttons[0].onclick = function(){  console.log("hey");  }

I have no clue at all why this works. Adding the button to the page and referring to it any other way did not work.

Byte is not a standard type in C/C++, so it is represented by char.

An advantage of this is that you can treat a basic_string as a byte array allowing for safe storage and function passing. This will help you avoid the memory leaks and segmentation faults you might encounter when using the various forms of char[] and char*.

For example, this creates a string as a byte array of null values:

typedef basic_string<unsigned char> u_string;

u_string bytes = u_string(16,'\0');

This allows for standard bitwise operations with other char values, including those stored in other string variables. For example, to XOR the char values of another u_string across bytes:

u_string otherBytes = "some more chars, which are just bytes";
for(int i = 0; i < otherBytes.length(); i++)
    bytes[i%16] ^= (int)otherBytes[i];

If you are using IIS 7.5 or later you can generate the machine key from IIS and save it directly to your web.config, within the web farm you then just copy the new web.config to each server.

1. Open IIS manager.
2. If you need to generate and save the MachineKey for all your applications select the server name in the left pane, in that case you will be modifying the root web.config file (which is placed in the .NET framework folder). If your intention is to create MachineKey for a specific web site/application then select the web site / application from the left pane. In that case you will be modifying the web.config file of your application.
3. Double-click the Machine Key icon in ASP.NET settings in the middle pane:
4. MachineKey section will be read from your configuration file and be shown in the UI. If you did not configure a specific MachineKey and it is generated automatically you will see the following options:
5. Now you can click Generate Keys on the right pane to generate random MachineKeys. When you click Apply, all settings will be saved in the web.config file.

Full Details can be seen @ Easiest way to generate MachineKey – Tips and tricks: ASP.NET, IIS and .NET development…

From your command line, we can see your jupyter server is running normally.The reason you can't access your remote jupyter server is that your remote centos6.5 server's firewall rules block the incoming request from your local browser,i.e. block your tcp:8045 port.
sudo ufw allow 80 # enable http server
sudo ufw allow 443 # enable https server
sudo ufw allow 8045 # enable your tcp:8045 port
then try to access your jupyter again.

Maybe you also need to uncomment and edit that place in your jupyter_notebook_config.py file:

c.NotebookApp.allow_remote_access = True

and even shut down your VPN if you have one.

Use this code:

<!DOCTYPE html>
<html>
<head>
<style>
.text-center{
    text-align:center;
    margin-left:auto;
    margin-right:auto;
}
</style>
</head>
<body>

<div class="text-center">
<canvas id="myCanvas" width="200" height="100" style="border:1px solid #000000;">
Your browser does not support the HTML5 canvas tag.

If you are using BaseFragment for your app then you can add onBackPressedDispatcher to your base fragment.

//Make a BaseFragment for all your fragments
abstract class BaseFragment : Fragment() {

private lateinit var callback: OnBackPressedCallback

/**
 * SetBackButtonDispatcher in OnCreate
 */

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setBackButtonDispatcher()
}

/**
 * Adding BackButtonDispatcher callback to activity
 */
private fun setBackButtonDispatcher() {
    callback = object : OnBackPressedCallback(true) {
        override fun handleOnBackPressed() {
            onBackPressed()
        }
    }
    requireActivity().onBackPressedDispatcher.addCallback(this, callback)
}

/**
 * Override this method into your fragment to handleBackButton
 */
  open fun onBackPressed() {
  }

}

Override onBackPressed() in your fragment by extending basefragment

//How to use this into your fragment
class MyFragment() : BaseFragment(){

private lateinit var mView: View

override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? {
    mView = inflater.inflate(R.layout.fragment_my, container, false)
    return mView.rootView
}

override fun onBackPressed() {
    //Write your code here on back pressed.
}

}

Use PREPARE/EXECUTE and querying the schema. The host doesn't need to have permission to create or run procedures :

SET @dbname = DATABASE();
SET @tablename = "tableName";
SET @columnname = "colName";
SET @preparedStatement = (SELECT IF(
  (
    SELECT COUNT(*) FROM INFORMATION_SCHEMA.COLUMNS
    WHERE
      (table_name = @tablename)
      AND (table_schema = @dbname)
      AND (column_name = @columnname)
  ) > 0,
  "SELECT 1",
  CONCAT("ALTER TABLE ", @tablename, " ADD ", @columnname, " INT(11);")
));
PREPARE alterIfNotExists FROM @preparedStatement;
EXECUTE alterIfNotExists;
DEALLOCATE PREPARE alterIfNotExists;

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

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

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

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

I'm not sure for UIImage, but this kind of behaviour usually occurs when coordinates are flipped. Most of OS X coordinate systems have their origin at the lower left corner, as in Postscript and PDF. But CGImage coordinate system has its origin at the upper left corner.

Possible solutions may involve an isFlipped property or a scaleYBy:-1 affine transform.

Just add

white-space: initial;

to the text, a line text will come automatically in the next line.

personaly, i'm using exceptions to handle validation. it requires following steps:

1. in your data binding expression, you need to add "ValidatesOnException=True"
2. in you data object you are binding to, you need to add DependencyPropertyChanged handler where you check if new value fulfills your conditions - if not - you restore to the object old value (if you need to) and you throw exception.
3. in your control template you use for displaying invalid value in the control, you can access Error collection and display exception message.

the trick here, is to bind only to objects which derive from DependencyObject. simple implementation of INotifyPropertyChanged wouldn't work - there is a bug in the framework, which prevents you from accessing error collection.

To understand this, you must take a step back. In OO, the customer owns the orders (orders are a list in the customer object). There can't be an order without a customer. So the customer seems to be the owner of the orders.

But in the SQL world, one item will actually contain a pointer to the other. Since there is 1 customer for N orders, each order contains a foreign key to the customer it belongs to. This is the "connection" and this means the order "owns" (or literally contains) the connection (information). This is exactly the opposite from the OO/model world.

This may help to understand:

public class Customer {
     // This field doesn't exist in the database
     // It is simulated with a SQL query
     // "OO speak": Customer owns the orders
     private List<Order> orders;
}

public class Order {
     // This field actually exists in the DB
     // In a purely OO model, we could omit it
     // "DB speak": Order contains a foreign key to customer
     private Customer customer;
}

The inverse side is the OO "owner" of the object, in this case the customer. The customer has no columns in the table to store the orders, so you must tell it where in the order table it can save this data (which happens via mappedBy).

Another common example are trees with nodes which can be both parents and children. In this case, the two fields are used in one class:

public class Node {
    // Again, this is managed by Hibernate.
    // There is no matching column in the database.
    @OneToMany(cascade = CascadeType.ALL) // mappedBy is only necessary when there are two fields with the type "Node"
    private List<Node> children;

    // This field exists in the database.
    // For the OO model, it's not really necessary and in fact
    // some XML implementations omit it to save memory.
    // Of course, that limits your options to navigate the tree.
    @ManyToOne
    private Node parent;
}

This explains for the "foreign key" many-to-one design works. There is a second approach which uses another table to maintain the relations. That means, for our first example, you have three tables: The one with customers, the one with orders and a two-column table with pairs of primary keys (customerPK, orderPK).

This approach is more flexible than the one above (it can easily handle one-to-one, many-to-one, one-to-many and even many-to-many). The price is that

• it's a bit slower (having to maintain another table and joins uses three tables instead of just two),
• the join syntax is more complex (which can be tedious if you have to manually write many queries, for example when you try to debug something)
• it's more error prone because you can suddenly get too many or too few results when something goes wrong in the code which manages the connection table.

That's why I rarely recommend this approach.

I'll try to keep this short, I've done this a few months ago for a game I was trying to build, it does a UDP "Client-Server" connection that acts like TCP, you can send (message) (message + object) using this. I've done some testing with it and it works just fine, feel free to modify it if needed.

According to the documentation:

Decorates Java projects and working sets that contain build path errors

In practice, I've found that a "build path error" may be caused by any number of reasons, depending on what plugins are active. Check the "Problems" view for more information.

Can you provide more info on the deployment failure? Is the application's failure to deploy triggering a .war.failed marker file?

The standalone instance Deployment folder ships with automatic deployment enabled by default. The automatic deployment mode automates the same functionality that you use with the manual mode, by using a series of marker files to indicate both the action and status of deployment to the runtime. For example, you can use the unix/linux "touch" command to create a .war.dodeploy marker file to tell the runtime to deploy the application.

It might be useful to know that there are in total five methods of deploying applications to AS7. I touched on this in another topic here : JBoss AS7 *.dodeploy files

I tend to use the Management Console for application management, but I know that the Management CLI is very popular among other uses also. Both are separate to the deployment folder processes. See how you go with the other methods to fit your needs.

If you search for "deploy" in the Admin Guide, you can see a section on the Deployment Scanner and a more general deployment section (including the CLI): https://docs.jboss.org/author/display/AS7/Admin+Guide

EDIT: look at this answer. Using np.cumsum is much faster than np.convolve

A quick and dirty way to smooth data I use, based on a moving average box (by convolution):

x = np.linspace(0,2*np.pi,100)
y = np.sin(x) + np.random.random(100) * 0.8

def smooth(y, box_pts):
    box = np.ones(box_pts)/box_pts
    y_smooth = np.convolve(y, box, mode='same')
    return y_smooth

plot(x, y,'o')
plot(x, smooth(y,3), 'r-', lw=2)
plot(x, smooth(y,19), 'g-', lw=2)

I believe you can also accomplish this quite simply as follows:

1. Convert Numpy array into a Pandas dataframe
2. Save as CSV

e.g. #1:

    # Libraries to import
    import pandas as pd
    import nump as np

    #N x N numpy array (dimensions dont matter)
    corr_mat    #your numpy array
    my_df = pd.DataFrame(corr_mat)  #converting it to a pandas dataframe

e.g. #2:

    #save as csv 
    my_df.to_csv('foo.csv', index=False)   # "foo" is the name you want to give
                                           # to csv file. Make sure to add ".csv"
                                           # after whatever name like in the code

Just for reference, if you are using:

 $(el).offset().top 

To get the position, it can be affected by the position of the parent element. Thus you may want to be consistent and use the following to set it:

$(el).offset({top: pos});

As opposed to the CSS methods above.

I might do

try{
    callback();
}catch(e){};

I know there's an accepted answer, but no one suggested this. I'm not really sure if this fits the description of idiomatic, but it works for all cases.

In newer JavaScript engines a finally can be used instead.

You can also make two random integers and verify if they are the same, this gives you more control over the probabilities.

Random rand = new Random();

Declare a range to manage random probability. In this example, there is a 50% chance of being true.

int range = 2;

Generate 2 random integers.

int a = rand.nextInt(range);
int b = rand.nextInt(range);

Then simply compare return the value.

return a == b; 

I also have a class you can use. RandomRange.java

 #more {
    background:none;
    border:none;
    color:#FFF;
    font-family:Verdana, Geneva, sans-serif;
    cursor: pointer;
}

If you want to change settings in the launcher, change icon size, or grid size just hold down on an empty part of your home screen. Tap the three Dots and there you go.

From https://forums.oneplus.net/threads/how-to-change-icon-and-grid-size-trebuchet-settings.84820/

When configuring the phone for first time I saw something about a grid somewhere, but couldn't find it again. Luckily I found the answer on the link above.

For Temporary change use following command

set global sql_mode="NO_BACKSLASH_ESCAPES,STRICT_TRANS_TABLE,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION" 

For permanent change : go to config file /etc/my.cnf or /etc/mysql/mysql.conf.d/mysqld.cnf and add following lines then restart mysql service

[mysqld]
sql_mode = "STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"

You need to use HttpContext.Current.Request.Cookies, not Response.Cookies.

Side note: cookies are copied to Request on Response.Cookies.Add, which makes check on either of them to behave the same for newly added cookies. But incoming cookies are never reflected in Response.

This behavior is documented in HttpResponse.Cookies property:

After you add a cookie by using the HttpResponse.Cookies collection, the cookie is immediately available in the HttpRequest.Cookies collection, even if the response has not been sent to the client.

<a data-title="A Title" data-placement="top" data-html="true" data-content="<form><input type='text'/></form>" data-trigger="hover" rel="popover" class="btn btn-primary" id="test">Top popover</a>

just state data-html="true"

I know this is a bit of an old question, but I've ended up making my own little class for it.

Might be useful to someone so I'll stick it up. I used a class variable, which is inherently persistent, to ensure sufficient whitespace was added to clear any old lines. See below:

class consolePrinter():
'''
Class to write to the console

Objective is to make it easy to write to console, with user able to 
overwrite previous line (or not)
'''
# -------------------------------------------------------------------------    
#Class variables
stringLen = 0    
# -------------------------------------------------------------------------    
    
# -------------------------------------------------------------------------
def writeline(stringIn, overwriteFlag=False):
    import sys
    #Get length of stringIn and update stringLen if needed
    if len(stringIn) > consolePrinter.stringLen:
        consolePrinter.stringLen = len(stringIn)+1
    
    ctrlString = "{:<"+str(consolePrinter.stringLen)+"}"
    if overwriteFlag:
        sys.stdout.write("\r" + ctrlString.format(stringIn))
    else:
        sys.stdout.write("\n" + stringIn)
    sys.stdout.flush()
    
    return

Which then is called via:

consolePrinter.writeline("text here", True) 

If you want to overwrite the previous line, or

consolePrinter.writeline("text here",False)

if you don't.

Note, for it to work right, all messages pushed to the console would need to be through consolePrinter.writeline.

<!DOCTYPE html>

including 4 sets of numbers would make it rgba, not cmyk, but either way would work (rgba= 00000088, cmyk= 0%, 0%, 0%, 50%)

The shortest way is: @RequestMapping({"", "/", "welcome"})

Although you can also do:

• @RequestMapping(value={"", "/", "welcome"})
• @RequestMapping(path={"", "/", "welcome"})

I had to exit XCode, delete DerivedData folder contents (~/Library/Developer/Xcode/DerivedData or /Library/Developer/Xcode/DerivedData) and exit simulator to make this work.

If you are running xampp on linux based image, to change root directory open:

/opt/lampp/etc/httpd.conf

Change default document root: DocumentRoot "/opt/lampp/htdocs" and <Directory "/opt/lampp/htdocs"

to your folder DocumentRoot "/opt/lampp/htdocs/myFolder" and <Directory "/opt/lampp/htdocs/myFolder">

To quickly see the differences with older revisions of a file:

git show -1 filename.txt > to compare against the last revision of file

git show -2 filename.txt > to compare against the 2nd last revision

git show -3 fielname.txt > to compare against the last 3rd last revision

The right way would be

[[[0 for _ in range(n)] for _ in range(n)] for _ in range(n)]

(What you're trying to do should be written like (for NxNxN)

[[[0]*n]*n]*n

but that is not correct, see @Adaman comment why).

Environment: Cordova 8.1.1, Android Studio 3.2, cordova-android 7.0.0

1. Set gradle PATH into .profile file.

export PATH="/Applications/Android Studio.app/Contents/gradle/gradle-4.6/bin":$PATH

2. Export the setting.

source ~/.profle

3. Now build cordova project.

cordova build android

PS: If [email protected] causes build error, downgrade your platform version to 6.3.0.

Use stored procedure that takes input data in form of xml to insert data.

From your c# code pass insert data as xml.

e.g in c#, syntax would be like this:

object id_application = db.ExecuteScalar("procSaveApplication", xml)

Using .data() will only add data to the jQuery object for that element. In order to add the information to the element itself you need to access that element using jQuery's .attr or native .setAttribute

$('div').attr('data-info', 1);
$('div')[0].setAttribute('data-info',1);

In order to access an element with the attribute set, you can simply select based on that attribute as you note in your post ($('div[data-info="1"]')), but when you use .data() you cannot. In order to select based on the .data() setting, you would need to use jQuery's filter function.

jsFiddle Demo

$('div').data('info', 1);_x000D_
//alert($('div').data('info'));//1_x000D_
_x000D_
$('div').filter(function(){_x000D_
   return $(this).data('info') == 1; _x000D_

You should follow the guidelines on Add a secondary horizontal axis:

Add a secondary horizontal axis

To complete this procedure, you must have a chart that displays a secondary vertical axis. To add a secondary vertical axis, see Add a secondary vertical axis.

1. Click a chart that displays a secondary vertical axis. This displays the Chart Tools, adding the Design, Layout, and Format tabs.

2. On the Layout tab, in the Axes group, click Axes.

   

3. Click Secondary Horizontal Axis, and then click the display option that you want.

Add a secondary vertical axis

You can plot data on a secondary vertical axis one data series at a time. To plot more than one data series on the secondary vertical axis, repeat this procedure for each data series that you want to display on the secondary vertical axis.

1. In a chart, click the data series that you want to plot on a secondary vertical axis, or do the following to select the data series from a list of chart elements:

   • Click the chart.

     This displays the Chart Tools, adding the Design, Layout, and Format tabs.

   • On the Format tab, in the Current Selection group, click the arrow in the Chart Elements box, and then click the data series that you want to plot along a secondary vertical axis.

     

2. On the Format tab, in the Current Selection group, click Format Selection. The Format Data Series dialog box is displayed.

   Note: If a different dialog box is displayed, repeat step 1 and make sure that you select a data series in the chart.

3. On the Series Options tab, under Plot Series On, click Secondary Axis and then click Close.

   A secondary vertical axis is displayed in the chart.

4. To change the display of the secondary vertical axis, do the following:

   • On the Layout tab, in the Axes group, click Axes.

   • Click Secondary Vertical Axis, and then click the display option that you want.

5. To change the axis options of the secondary vertical axis, do the following:

   • Right-click the secondary vertical axis, and then click Format Axis.

   • Under Axis Options, select the options that you want to use.

text.Trim() is to be used

string txt = "                   i am a string                                    ";
txt = txt.Trim();

You have to use curly braces ({}) to access fields, since the fieldnames function returns a cell array of strings:

for i = 1:numel(fields)

Using parentheses to access data in your cell array will just return another cell array, which is displayed differently from a character array:

>> fields(1)  % Get the first cell of the cell array

ans = 

    'a'       % This is how the 1-element cell array is displayed

>> fields{1}  % Get the contents of the first cell of the cell array

ans =

a             % This is how the single character is displayed

I really liked the answer provided by Aaron Digulla but needed to keep my array of objects so I could iterate through it later. So I modified it to

 var indexer = {};_x000D_
 for (var i = 0; i < array.length; i++) {_x000D_
     indexer[array[i].id] = parseInt(i);_x000D_
 }_x000D_
 _x000D_
 //Then you can access object properties in your array using _x000D_
 array[indexer[id]].property

Question : Give the informations of abc

    a = ['abc-123', 'def-456', 'ghi-789', 'abc-456']


    aa = [ string for string in a if  "abc" in string]
    print(aa)

Output =>  ['abc-123', 'abc-456']

It depends on what you define as the difference. To compare two dates at midnight you can do.

long day1 = ...; // in milliseconds.
long day2 = ...; // in milliseconds.
long days = (day2 - day1) / 86400000;

If your app is in background, Firebase will not trigger onMessageReceived(). onMessageReceived() is called when app is in foreground . When app is in background,onMessageReceived() method will be called only if the body of https://fcm.googleapis.com/fcm/send contain only data payload.Here ,i just created a method to build custom notification with intent having ur your required activity . and called this method in onMessageRecevied() .

In PostMan:

uri: https://fcm.googleapis.com/fcm/send

header:Authorization:key=ur key

body --->>

{  "data" : {
      "Nick" : "Mario",
      "Room" : "PoSDenmark",

    },

  "to" : "xxxxxxxxx"

}

in your application.

class MyFirebaseMessagingService  extends FirebaseMessagingService {

 public void onMessageReceived(RemoteMessage remoteMessage) {
       if (remoteMessage.getData().size() > 0) {
           sendNotification("ur message body") ;
        }
    }
private void sendNotification(String messageBody) {
        Intent intent = new Intent(this, Main2Activity.class);
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
                PendingIntent.FLAG_ONE_SHOT);

        Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.ic_stat_ic_notification)
                .setContentTitle("FCM Message")
                .setContentText(messageBody)
                .setAutoCancel(true)
                .setSound(defaultSoundUri)
                .setContentIntent(pendingIntent);

        NotificationManager notificationManager =
                (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

        notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
    }

 }

when the data payload comes to the mobile,then onMessageReceived() method will be called.. inside that method ,i just made a custom notification. this will work even if ur app is background or foreground.

Go to Manage Access page under settings (https://github.com/user/repo/settings/access) and add the collaborators as needed.

Screenshot:

To answer your question, these should work as long as:

• Your HTTP server passes these values along to PHP (I don't know any that don't)
• You're not accessing the script via command line (CLI)

But, if I remember correctly, these values can be faked to an extent, so it's best not to rely on them.

My personal preference is to set the domain name as an environment variable in the apache2 virtual host:

# Virtual host
setEnv DOMAIN_NAME example.com

And read it in PHP:

// PHP
echo getenv(DOMAIN_NAME);

This, however, isn't applicable in all circumstances.

I have same problem for image which is not showing correctly in outlook.and I am using px and % for applying height and width for image. but when i removed px and % and using only just whatever the value in html it is worked for me. For example i was using : width="800px" now I'm using widht="800" and problem is resolved for me.

Working with Python 2.7.6 and 2.7.13

import urllib2  
req = urllib2.Request('http://icanhazip.com', data=None)  
response = urllib2.urlopen(req, timeout=5)  
print(response.read())

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

public ActionResult DetailsData(int? k)
    {

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

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

You can divide seconds by 60 to get the minutes

import time
seconds = time.time()
minutes = seconds / 60
print(minutes)

When you divide it by 60 again, you will get the hours

$(document).prop('title', 'test');

This is simply a JQuery wrapper for:

document.title = 'test';

To add a > periodically you can do:

function changeTitle() {
    var title = $(document).prop('title'); 
    if (title.indexOf('>>>') == -1) {
        setTimeout(changeTitle, 3000);  
        $(document).prop('title', '>'+title);
    }
}

changeTitle();

Had the same issue recently, solved by adding traditional: true,

for example we want to set a DataTable 'Users' to DataGridView by followig 2 steps : step 1 - get all Users by :

public DataTable  getAllUsers()
    {
        OracleConnection Connection = new OracleConnection(stringConnection);
        Connection.ConnectionString = stringConnection;
        Connection.Open();

        DataSet dataSet = new DataSet();

        OracleCommand cmd = new OracleCommand("semect * from Users");
        cmd.CommandType = CommandType.Text;
        cmd.Connection = Connection;

        using (OracleDataAdapter dataAdapter = new OracleDataAdapter())
        {
            dataAdapter.SelectCommand = cmd;
            dataAdapter.Fill(dataSet);
        }

        return dataSet.Tables[0];
    }

step 2- set the return result to DataGridView :

public void setTableToDgv(DataGridView DGV, DataTable table)
    {
        DGV.DataSource = table;
    }

using example:

    setTableToDgv(dgv_client,getAllUsers());

Use this one: box-shadow: 0px 0px 0px 1px red;

If using make, issue with -j. From man make:

  -j [jobs], --jobs[=jobs]
       Specifies the number of jobs (commands) to run simultaneously.  
       If there is more than one -j option, the last one is effective.
       If the -j option is given without an argument, make will not limit the
       number of jobs that can run simultaneously.

And most notably, if you want to script or identify the number of cores you have available (depending on your environment, and if you run in many environments, this can change a lot) you may use ubiquitous Python function cpu_count():

https://docs.python.org/3/library/multiprocessing.html#multiprocessing.cpu_count

Like this:

make -j $(python3 -c 'import multiprocessing as mp; print(int(mp.cpu_count() * 1.5))')

If you're asking why 1.5 I'll quote user artless-noise in a comment above:

The 1.5 number is because of the noted I/O bound problem. It is a rule of thumb. About 1/3 of the jobs will be waiting for I/O, so the remaining jobs will be using the available cores. A number greater than the cores is better and you could even go as high as 2x.

I am actually quite surprised that this solution has not been presented yet, and I feel like it is the easiest solution.

Go to GitHub, find the version of the brewfile that matches the version of icu4c that you need and get the raw version of the file (follow the links above and click View File then Raw).

Then just have brew reinstall from that url.

For example, version 62.1:

brew reinstall https://raw.githubusercontent.com/Homebrew/homebrew-core/575eb4bbef683551e19f329f60456b13a558132f/Formula/icu4c.rb

For example, version 64.2:

brew reinstall https://raw.githubusercontent.com/Homebrew/homebrew-core/a806a621ed3722fb580a58000fb274a2f2d86a6d/Formula/icu4c.rb

Adding some information here that I experienced:

fragment.isVisible is only working (true/false) when you replaceFragment() otherwise if you work with addFragment(), isVisible always returns true whether the fragment is in behind of some other fragment.

I answered a similar question here

As @Syden said, the mixins will work. Another option is using SASS map-get like this..

@media (min-width: map-get($grid-breakpoints, sm)){
  .something {
    padding: 10px;
   }
}

@media (min-width: map-get($grid-breakpoints, md)){
  .something {
    padding: 20px;
   }
}

Yes, opacity can only work on top-level windows. It uses a hardware feature of the video adapter, that doesn't support child windows, like Panel. The only top-level Control derived class in Winforms is Form.

Several of the 'pure' Winform controls, the ones that do their own painting instead of letting a native Windows control do the job, do however support a transparent BackColor. Panel is one of them. It uses a trick, it asks the Parent to draw itself to produce the background pixels. One side-effect of this trick is that overlapping controls doesn't work, you only see the parent pixels, not the overlapped controls.

This sample form shows it at work:

public partial class Form1 : Form {
    public Form1() {
        InitializeComponent();
        this.BackColor = Color.White;
        panel1.BackColor = Color.FromArgb(25, Color.Black);
    }
    protected override void OnPaint(PaintEventArgs e) {
        e.Graphics.DrawLine(Pens.Yellow, 0, 0, 100, 100);
    }
}

If that's not good enough then you need to consider stacking forms on top of each other. Like this.

Notable perhaps is that this restriction is lifted in Windows 8. It no longer uses the video adapter overlay feature and DWM (aka Aero) cannot be turned off anymore. Which makes opacity/transparency on child windows easy to implement. Relying on this is of course future-music for a while to come. Windows 7 will be the next XP :)

UPDATE only changes the values you specify:

UPDATE table SET cell='new_value' WHERE whatever='somevalue'

You shouldn't use Exceptions to validate your values.

For single character there is a simple solution:

Character.isDigit()

For longer values it's better to use some utils. NumberUtils provided by Apache would work perfectly here:

NumberUtils.isNumber()

if you're using React I found 'react-moment' library more easy to handle for Front-End related tasks, just import <Moment> component and add unix prop:

import Moment from 'react-moment'

 // get date variable
 const {date} = this.props 

 <Moment unix>{date}</Moment>

Andrey Tarasevich provides the following explanation:

1. On Google Groups
2. On bytes.com

[Minor changes to formatting made. Parenthetical annotations added in square brackets []].

The whole idea of using 'do/while' version is to make a macro which will expand into a regular statement, not into a compound statement. This is done in order to make the use of function-style macros uniform with the use of ordinary functions in all contexts.

Consider the following code sketch:

if (<condition>)
  foo(a);
else
  bar(a);

where foo and bar are ordinary functions. Now imagine that you'd like to replace function foo with a macro of the above nature [named CALL_FUNCS]:

if (<condition>)
  CALL_FUNCS(a);
else
  bar(a);

Now, if your macro is defined in accordance with the second approach (just { and }) the code will no longer compile, because the 'true' branch of if is now represented by a compound statement. And when you put a ; after this compound statement, you finished the whole if statement, thus orphaning the else branch (hence the compilation error).

One way to correct this problem is to remember not to put ; after macro "invocations":

if (<condition>)
  CALL_FUNCS(a)
else
  bar(a);

This will compile and work as expected, but this is not uniform. The more elegant solution is to make sure that macro expand into a regular statement, not into a compound one. One way to achieve that is to define the macro as follows:

#define CALL_FUNCS(x) \
do { \
  func1(x); \
  func2(x); \
  func3(x); \
} while (0)

Now this code:

if (<condition>)
  CALL_FUNCS(a);
else
  bar(a);

will compile without any problems.

However, note the small but important difference between my definition of CALL_FUNCS and the first version in your message. I didn't put a ; after } while (0). Putting a ; at the end of that definition would immediately defeat the entire point of using 'do/while' and make that macro pretty much equivalent to the compound-statement version.

I don't know why the author of the code you quoted in your original message put this ; after while (0). In this form both variants are equivalent. The whole idea behind using 'do/while' version is not to include this final ; into the macro (for the reasons that I explained above).

You can use from the pd.to_numeric(s)

The different between getTextBounds and measureText is described with the image below.

In short,

1. getTextBounds is to get the RECT of the exact text. The measureText is the length of the text, including the extra gap on the left and right.

2. If there are spaces between the text, it is measured in measureText but not including in the length of the TextBounds, although the coordinate get shifted.

3. The text could be tilted (Skew) left. In this case, the bounding box left side would exceed outside the measurement of the measureText, and the overall length of the text bound would be bigger than measureText

4. The text could be tilted (Skew) right. In this case, the bounding box right side would exceed outside the measurement of the measureText, and the overall length of the text bound would be bigger than measureText

You can use the tableView:willDisplayCell method to do all the kinds of customization to a tableViewCell.

- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
{
     [cell setSelectionStyle:UITableViewCellSelectionStyleNone];
     [cell setUserInteractionEnabled:NO];

     if (indexPath.section == 1 && indexPath.row == 0)
     {
         [cell setSelectionStyle:UITableViewCellSelectionStyleGray];
         [cell setUserInteractionEnabled:YES];
     }
} 

In this above code, the user can only select the first row in the second section of the tableView. The rest all rows can't be selected. Thanks!~

Short Answer: Invoke draggable on the legend and interactively move it wherever you want:

ax.legend().draggable()

Long Answer: If you rather prefer to place the legend interactively/manually rather than programmatically, you can toggle the draggable mode of the legend so that you can drag it to wherever you want. Check the example below:

import matplotlib.pylab as plt
import numpy as np
#define the figure and get an axes instance
fig = plt.figure()
ax = fig.add_subplot(111)
#plot the data
x = np.arange(-5, 6)
ax.plot(x, x*x, label='y = x^2')
ax.plot(x, x*x*x, label='y = x^3')
ax.legend().draggable()
plt.show()

1) HTML is downloaded.

2) HTML is parsed progressively. When a request for an asset is reached the browser will attempt to download the asset. A default configuration for most HTTP servers and most browsers is to process only two requests in parallel. IE can be reconfigured to downloaded an unlimited number of assets in parallel. Steve Souders has been able to download over 100 requests in parallel on IE. The exception is that script requests block parallel asset requests in IE. This is why it is highly suggested to put all JavaScript in external JavaScript files and put the request just prior to the closing body tag in the HTML.

3) Once the HTML is parsed the DOM is rendered. CSS is rendered in parallel to the rendering of the DOM in nearly all user agents. As a result it is strongly recommended to put all CSS code into external CSS files that are requested as high as possible in the <head></head> section of the document. Otherwise the page is rendered up to the occurance of the CSS request position in the DOM and then rendering starts over from the top.

4) Only after the DOM is completely rendered and requests for all assets in the page are either resolved or time out does JavaScript execute from the onload event. IE7, and I am not sure about IE8, does not time out assets quickly if an HTTP response is not received from the asset request. This means an asset requested by JavaScript inline to the page, that is JavaScript written into HTML tags that is not contained in a function, can prevent the execution of the onload event for hours. This problem can be triggered if such inline code exists in the page and fails to execute due to a namespace collision that causes a code crash.

Of the above steps the one that is most CPU intensive is the parsing of the DOM/CSS. If you want your page to be processed faster then write efficient CSS by eliminating redundent instructions and consolidating CSS instructions into the fewest possible element referrences. Reducing the number of nodes in your DOM tree will also produce faster rendering.

Keep in mind that each asset you request from your HTML or even from your CSS/JavaScript assets is requested with a separate HTTP header. This consumes bandwidth and requires processing per request. If you want to make your page load as fast as possible then reduce the number of HTTP requests and reduce the size of your HTML. You are not doing your user experience any favors by averaging page weight at 180k from HTML alone. Many developers subscribe to some fallacy that a user makes up their mind about the quality of content on the page in 6 nanoseconds and then purges the DNS query from his server and burns his computer if displeased, so instead they provide the most beautiful possible page at 250k of HTML. Keep your HTML short and sweet so that a user can load your pages faster. Nothing improves the user experience like a fast and responsive web page.

Primitive data types cannot be null. Only Object data types can be null.

int, long, etc... can't be null.

If you use Long (wrapper class for long) then you can check for null's:

Long longValue = null;

if(longValue == null)

You were close:

IF EXISTS (SELECT * FROM Table WHERE FieldValue='')
   SELECT TableID FROM Table WHERE FieldValue=''
ELSE
BEGIN
   INSERT INTO TABLE (FieldValue) VALUES ('')
   SELECT TableID FROM Table WHERE TableID=SCOPE_IDENTITY()
END

This is a few months late, but I have created PR#6251 with matplotlib to add a new PercentFormatter class. With this class you just need one line to reformat your axis (two if you count the import of matplotlib.ticker):

import ...
import matplotlib.ticker as mtick

ax = df['myvar'].plot(kind='bar')
ax.yaxis.set_major_formatter(mtick.PercentFormatter())

PercentFormatter() accepts three arguments, xmax, decimals, symbol. xmax allows you to set the value that corresponds to 100% on the axis. This is nice if you have data from 0.0 to 1.0 and you want to display it from 0% to 100%. Just do PercentFormatter(1.0).

The other two parameters allow you to set the number of digits after the decimal point and the symbol. They default to None and '%', respectively. decimals=None will automatically set the number of decimal points based on how much of the axes you are showing.

Update

PercentFormatter was introduced into Matplotlib proper in version 2.1.0.

In some cases when using numpy arrays, using random.shuffle created duplicate data in the array.

An alternative is to use numpy.random.shuffle. If you're working with numpy already, this is the preferred method over the generic random.shuffle.

numpy.random.shuffle

Example

>>> import numpy as np
>>> import random

Using random.shuffle:

>>> foo = np.array([[1,2,3],[4,5,6],[7,8,9]])
>>> foo

array([[1, 2, 3],
       [4, 5, 6],
       [7, 8, 9]])


>>> random.shuffle(foo)
>>> foo

array([[1, 2, 3],
       [1, 2, 3],
       [4, 5, 6]])

Using numpy.random.shuffle:

>>> foo = np.array([[1,2,3],[4,5,6],[7,8,9]])
>>> foo

array([[1, 2, 3],
       [4, 5, 6],
       [7, 8, 9]])


>>> np.random.shuffle(foo)
>>> foo

array([[1, 2, 3],
       [7, 8, 9],
       [4, 5, 6]])

On older versions of Docker it seems you need to use this order:

docker build -t tag .

and not

docker build . -t tag

A loading indicator is simply an animated image (.gif) that is displayed until the completed event is called on the AJAX request. http://ajaxload.info/ offers many options for generating loading images that you can overlay on your modals. To my knowledge, Bootstrap does not provide the functionality built-in.

You can try ng-file-upload angularjs plugin (instead of ng-upload).

It's fairly easy to setup and deal with angularjs specifics. It also supports progress, cancel, drag and drop and is cross browser.

html

<!-- Note: MUST BE PLACED BEFORE angular.js-->
<script src="ng-file-upload-shim.min.js"></script> 
<script src="angular.min.js"></script>
<script src="ng-file-upload.min.js"></script> 

<div ng-controller="MyCtrl">
  <input type="file" ngf-select="onFileSelect($files)" multiple>
</div>

JS:

//inject angular file upload directives and service.
angular.module('myApp', ['ngFileUpload']);

var MyCtrl = [ '$scope', '$upload', function($scope, $upload) {
  $scope.onFileSelect = function($files) {
    //$files: an array of files selected, each file has name, size, and type.
    for (var i = 0; i < $files.length; i++) {
      var file = $files[i];
      $scope.upload = $upload.upload({
        url: 'server/upload/url', //upload.php script, node.js route, or servlet url
        data: {myObj: $scope.myModelObj},
        file: file,
      }).progress(function(evt) {
        console.log('percent: ' + parseInt(100.0 * evt.loaded / evt.total));
      }).then(function(response) {
        var data = response.data;
        // file is uploaded successfully
        console.log(data);
      });
    }
  };
}];

If you want to get a list of all tablespaces used in the current database instance, you can use the DBA_TABLESPACES view as shown in the following SQL script example:

SQL> connect SYSTEM/fyicenter
Connected.

SQL> SELECT TABLESPACE_NAME, STATUS, CONTENTS
  2  FROM USER_TABLESPACES;
TABLESPACE_NAME                STATUS    CONTENTS
------------------------------ --------- ---------
SYSTEM                         ONLINE    PERMANENT
UNDO                           ONLINE    UNDO
SYSAUX                         ONLINE    PERMANENT
TEMP                           ONLINE    TEMPORARY
USERS                          ONLINE    PERMANENT

http://dba.fyicenter.com/faq/oracle/Show-All-Tablespaces-in-Current-Database.html

If you need the value before insert a row:

CREATE FUNCTION `getAutoincrementalNextVal`(`TableName` VARCHAR(50))
    RETURNS BIGINT
    LANGUAGE SQL
    NOT DETERMINISTIC
    CONTAINS SQL
    SQL SECURITY DEFINER
    COMMENT ''
BEGIN

    DECLARE Value BIGINT;

    SELECT
        AUTO_INCREMENT INTO Value
    FROM
        information_schema.tables
    WHERE
        table_name = TableName AND
        table_schema = DATABASE();

    RETURN Value;

END

You can use this in a insert:

INSERT INTO
    document (Code, Title, Body)
VALUES (                
    sha1( concat (convert ( now() , char), ' ',   getAutoincrementalNextval ('document') ) ),
    'Title',
    'Body'
);

@andrey answer in one line (tested in Swift 4.1):

extension UIResponder {
    public var parentViewController: UIViewController? {
        return next as? UIViewController ?? next?.parentViewController
    }
}

usage:

 let vc: UIViewController = view.parentViewController

Here's example with simple object exporting.

var MyScreen = {

    /* ... */

    width : function (percent){

        return window.innerWidth / 100 * percent

    }

    height : function (percent){

        return window.innerHeight / 100 * percent

    }


};

export default MyScreen

In main file (Use when you don't want and don't need to create new instance) and it is not global you will import this only when it needed :

import MyScreen from "./module/screen";
console.log( MyScreen.width(100) );

Come on guys :) We could do it simpler, by examples:

/this-is-an-endpoint
/another/endpoint
/some/other/endpoint
/login
/accounts
/cart/items

and when put under a domain, it would look like:

https://example.com/this-is-an-endpoint
https://example.com/another/endpoint
https://example.com/some/other/endpoint
https://example.com/login
https://example.com/accounts
https://example.com/cart/items

Can be either http or https, we use https in the example.

Also endpoint can be different for different HTTP methods, for example:

GET /item/{id}
PUT /item/{id}

would be two different endpoints - one for retrieving (as in "cRud" abbreviation), and the other for updating (as in "crUd")

And that's all, really that simple!

You can use like this:

String Query = "Select * from " + TABLE_NAME + " where " + Cust_id + " = " + cust_no;

Cursor cursorr = db.rawQuery(Query, null);

I found out how to do this on the Android emulator itself (Menu, "Settings" App - not the settings of the emulator outside). All you need to do is:

open settings app -> Language & Input -> Go to the "Keyboard & Input Methods -> click Default

This will bring up a Dialog in which case you can then disable the Hardware Keyboard by switching the hardware keyboard from on to off. This will disable the Hardware keyboard and enable the softkeyboard.

This may help:

private void textBox1_KeyDown(object sender, KeyEventArgs e)
{
    //
    // Detect the KeyEventArg's key enumerated constant.
    //
    if (e.KeyCode == Keys.Enter)
    {
        MessageBox.Show("You pressed enter! Good job!");
    }
}

Don't forget that you can always cut and paste into the minibuffer.

So you can just copy a newline character (or any string) from your buffer, then yank it when prompted for the replacement text.

Make sure that your sas.png is marked as Build Action: Content and Copy To Output Directory: Copy Always in its Visual Studio Properties...

I think the C# source code goes like this...

Image image = new Image();
image.Source = (new ImageSourceConverter()).ConvertFromString("pack://application:,,,/Bilder/sas.png") as ImageSource;

and XAML should be

<Image Height="200" HorizontalAlignment="Left" Margin="12,12,0,0" 
       Name="image1" Stretch="Fill" VerticalAlignment="Top" 
       Source="../Bilder/sas.png"
       Width="350" />  

EDIT

Dynamically I think XAML would provide best way to load Images ...

<Image Source="{Binding Converter={StaticResource MyImageSourceConverter}}"
       x:Name="MyImage"/>

where image.DataContext is string path.

MyImage.DataContext = "pack://application:,,,/Bilder/sas.png";

public class MyImageSourceConverter : IValueConverter
{
    public object Convert(object value_, Type targetType_, 
    object parameter_, System.Globalization.CultureInfo culture_)
    {
        return (new ImageSourceConverter()).ConvertFromString (value.ToString());
    }

    public object ConvertBack(object value, Type targetType, 
    object parameter, CultureInfo culture)
    {
          throw new NotImplementedException();
    }
}

Now as you set a different data context, Image would be automatically loaded at runtime.

-- c#.net

NORMALIZE this.WindowState = FormWindowState.Normal;

this.WindowState = FormWindowState.Minimized;

Since you want to pivot multiple columns of data, I would first suggest unpivoting the result, score and grade columns so you don't have multiple columns but you will have multiple rows.

Depending on your version of SQL Server you can use the UNPIVOT function or CROSS APPLY. The syntax to unpivot the data will be similar to:

select ratio, col, value
from GRAND_TOTALS
cross apply
(
  select 'result', cast(result as varchar(10)) union all
  select 'score', cast(score as varchar(10)) union all
  select 'grade', grade
) c(col, value)

See SQL Fiddle with Demo. Once the data has been unpivoted, then you can apply the PIVOT function:

select ratio = col,
  [current ratio], [gearing ratio], [performance ratio], total
from
(
  select ratio, col, value
  from GRAND_TOTALS
  cross apply
  (
    select 'result', cast(result as varchar(10)) union all
    select 'score', cast(score as varchar(10)) union all
    select 'grade', grade
  ) c(col, value)
) d
pivot
(
  max(value)
  for ratio in ([current ratio], [gearing ratio], [performance ratio], total)
) piv;

See SQL Fiddle with Demo. This will give you the result:

|  RATIO | CURRENT RATIO | GEARING RATIO | PERFORMANCE RATIO |     TOTAL |
|--------|---------------|---------------|-------------------|-----------|
|  grade |          Good |          Good |      Satisfactory |      Good |
| result |       1.29400 |       0.33840 |           0.04270 |    (null) |
|  score |      60.00000 |      70.00000 |          50.00000 | 180.00000 |

just put chart

$('#container').highcharts({
colors: ['#31BFA2'], // change color here
chart: {
        type: 'column'
}, .... Continue chart

only add AsEnumerable() :

public IQueryable<Product> GetProducts(int categoryID)
{
    return from p in db.Products.AsEnumerable()
           where p.CategoryID== categoryID
           select new Product { Name = p.Name};
}

Here's yet another take on it (also using AppleScript):

function newincmd() { 
   declare args 
   # escape single & double quotes 
   args="${@//\'/\'}" 
   args="${args//\"/\\\"}" 
   printf "%s" "${args}" | /usr/bin/pbcopy 
   #printf "%q" "${args}" | /usr/bin/pbcopy 
   /usr/bin/open -a Terminal 
   /usr/bin/osascript -e 'tell application "Terminal" to do script with command "/usr/bin/clear; eval \"$(/usr/bin/pbpaste)\""' 
   return 0 
} 

newincmd ls 

newincmd echo "hello \" world" 
newincmd echo $'hello \' world' 

see: codesnippets.joyent.com/posts/show/1516

It depends on the tools you can use. I doubt there is a JavaScript too that could do it directly within the browser. It also depends if it's a one-off (always the same key) or whether you need to script it.

Command-line / OpenSSL

If you want to use something like OpenSSL on a unix command line, you can do something as follows. I'm assuming you public.key file contains something like this:

-----BEGIN PUBLIC KEY-----
MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAmBAjFv+29CaiQqYZIw4P
J0q5Qz2gS7kbGleS3ai8Xbhu5n8PLomldxbRz0RpdCuxqd1yvaicqpDKe/TT09sR
mL1h8Sx3Qa3EQmqI0TcEEqk27Ak0DTFxuVrq7c5hHB5fbJ4o7iEq5MYfdSl4pZax
UxdNv4jRElymdap8/iOo3SU1RsaK6y7kox1/tm2cfWZZhMlRFYJnpoXpyNYrp+Yo
CNKxmZJnMsS698kaFjDlyznLlihwMroY0mQvdD7dCeBoVlfPUGPAlamwWyqtIU+9
5xVkSp3kxcNcNb/mePSKQIPafQ1sAmBKPwycA/1I5nLzDVuQa95ZWMn0JkphtFIh
HQIDAQAB
-----END PUBLIC KEY-----

Then, the commands would be:

PUBKEY=`grep -v -- ----- public.key | tr -d '\n'`

Then, you can look into the ASN.1 structure:

echo $PUBKEY | base64 -d | openssl asn1parse -inform DER -i

This should give you something like this:

    0:d=0  hl=4 l= 290 cons: SEQUENCE          
    4:d=1  hl=2 l=  13 cons:  SEQUENCE          
    6:d=2  hl=2 l=   9 prim:   OBJECT            :rsaEncryption
   17:d=2  hl=2 l=   0 prim:   NULL              
   19:d=1  hl=4 l= 271 prim:  BIT STRING 

The modulus and public exponent are in the last BIT STRING, offset 19, so use -strparse:

 echo $PUBKEY | base64 -d | openssl asn1parse -inform DER -i -strparse 19

This will give you the modulus and the public exponent, in hexadecimal (the two INTEGERs):

    0:d=0  hl=4 l= 266 cons: SEQUENCE          
    4:d=1  hl=4 l= 257 prim:  INTEGER           :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
  265:d=1  hl=2 l=   3 prim:  INTEGER           :010001

That's probably fine if it's always the same key, but this is probably not very convenient to put in a script.

Alternatively (and this might be easier to put into a script),

openssl rsa -pubin -inform PEM -text -noout < public.key

will return this:

Modulus (2048 bit):

Java

It depends on the input format. If it's an X.509 certificate in a keystore, use (RSAPublicKey)cert.getPublicKey(): this object has two getters for the modulus and the exponent.

If it's in the format as above, you might want to use BouncyCastle and its PEMReader to read it. I haven't tried the following code, but this would look more or less like this:

PEMReader pemReader = new PEMReader(new FileReader("file.pem"));
Object obj = pemReader.readObject();
pemReader.close();
if (obj instanceof X509Certificate) {
   // Just in case your file contains in fact an X.509 certificate,
   // useless otherwise.
   obj = ((X509Certificate)obj).getPublicKey();
}
if (obj instanceof RSAPublicKey) {
   // ... use the getters to get the BigIntegers.
}

(You can use BouncyCastle similarly in C# too.)

Here are all the possible problems/solutions I have come across:

1. Download the cookie plugin

$.cookie is not a standard jQuery function and the plugin needs to be downloaded here. Make sure to include the appropriate <script> tag where necessary (see next).

2. Include jQuery before the cookie plugin

When including the cookie script, make sure to include jQuery FIRST, then the cookie plugin.

<script src="~/Scripts/jquery-2.0.3.js" type="text/javascript"></script>
<script src="~/Scripts/jquery_cookie.js" type="text/javascript"></script>

3. Don't include jQuery more than once

This was my problem. Make sure you aren't including jQuery more than once. If you are, it is possible that:

1. jQuery loads correctly.
2. The cookie plugin loads correctly.
3. Your second inclusion of jQuery overwrites the first and destroys the cookie plugin.

For anyone using ASP.Net MVC projects, be careful with the default javascript bundle inclusions. My second inclusion of jQuery was within one of my global layout pages under the line @Scripts.Render("~/bundles/jquery").

4. Rename the plugin file to not include ".cookie"

In some rare cases, renaming the file to something that does NOT include ".cookie" has fixed this error, apparently due to web server issues. By default, the downloaded script is titled "jquery.cookie.js" but try renaming it to something like "jquery_cookie.js" as shown above. More details on this problem are here.

A much simpler solution:

<script language="javascript" src="http://maps.google.com/maps/api/js?v=3.2&sensor=false"></script>

and later in the code:

var online;
// check whether this function works (online only)
try {
  var x = google.maps.MapTypeId.TERRAIN;
  online = true;
} catch (e) {
  online = false;
}
console.log(online);

When not online the google script will not be loaded thus resulting in an error where an exception will be thrown.

I have checked a variable if it is a boolean or not as below

console.log(isBoolean(this.myVariable));

Similarly we have

isNumber(this.myVariable);
isString(this.myvariable);

and so on.

Because python checks in the directories in sequential order starting at the first directory in sys.path list, till it find the .py file it was looking for.

Ideally, the current directory or the directory of the script is the first always the first element in the list, unless you modify it, like you did. From documentation -

As initialized upon program startup, the first item of this list, path[0], is the directory containing the script that was used to invoke the Python interpreter. If the script directory is not available (e.g. if the interpreter is invoked interactively or if the script is read from standard input), path[0] is the empty string, which directs Python to search modules in the current directory first. Notice that the script directory is inserted before the entries inserted as a result of PYTHONPATH.

So, most probably, you had a .py file with the same name as the module you were trying to import from, in the current directory (where the script was being run from).

Also, a thing to note about ImportErrors , lets say the import error says - ImportError: No module named main - it doesn't mean the main.py is overwritten, no if that was overwritten we would not be having issues trying to read it. Its some module above this that got overwritten with a .py or some other file.

Example -

My directory structure looks like -

 - test
    - shared
         - __init__.py
         - phtest.py
  - testmain.py

Now From testmain.py , I call from shared import phtest , it works fine.

Now lets say I introduce a shared.py in test directory` , example -

 - test
    - shared
         - __init__.py
         - phtest.py
  - testmain.py 
  - shared.py

Now when I try to do from shared import phtest from testmain.py , I will get the error -

ImportError: cannot import name 'phtest'

As you can see above, the file that is causing the issue is shared.py , not phtest.py .

The observe function below will allow you to listen to elements via a selector.

In the following example, after 2 seconds have passed, a .greeting will be inserted into the .container. Since we are listening to the insertion of this element, we can have a callback that triggers upon insertion.

const observe = (selector, callback, targetNode = document.body) =>
  new MutationObserver(mutations => [...mutations]
    .flatMap((mutation) => [...mutation.addedNodes])
    .filter((node) => node.matches && node.matches(selector))
    .forEach(callback))
  .observe(targetNode, { childList: true, subtree: true });

const createGreeting = () => {
  const el = document.createElement('DIV');
  el.textContent = 'Hello World';
  el.classList.add('greeting');
  return el;
};

const container = document.querySelector('.container');

observe('.greeting', el => console.log('I have arrived!', el), container);

new Promise(res => setTimeout(() => res(createGreeting()), 2000))
  .then(el => container.appendChild(el));

html, body { width: 100%; height: 100%; margin: 0; padding: 0; }
body { display: flex; }
.container { display: flex; flex: 1; align-items: center; justify-content: center; }
.greeting { font-weight: bold; font-size: 2em; }

<div class="container"></div>

You'll need to consider this in context of the application. In general, you should design an application, not a database (the database simply being part of the application).

Consider how your application should respond to various cases.

The default action is to restrict (i.e. not permit) the operation, which is normally what you want as it prevents stupid programming errors. However, on DELETE CASCADE can also be useful. It really depends on your application and how you intend to delete particular objects.

Personally, I'd use InnoDB because it doesn't trash your data (c.f. MyISAM, which does), rather than because it has FK constraints.

It's rather safe to add @SafeVarargs annotation to the method when you can control the way it's called (e.g. a private method of a class). You must make sure that only the instances of the declared generic type are passed to the method.

If the method exposed externally as a library, it becomes hard to catch such mistakes. In this case it's best to avoid this annotation and rewrite the solution with a collection type (e.g. Collection<Type1<Type2>>) input instead of varargs (Type1<Type2>...).

As for the naming, the term heap pollution phenomenon is quite misleading in my opinion. In the documentation the actual JVM heap is not event mentioned. There is a question at Software Engineering that contains some interesting thoughts on the naming of this phenomenon.

I think the best, simplest and securest method is to open your instagram profile in a browser, view source code and look for user variable (ctrl+f "user":{") inside main javascript code. The id number inside user variable should be your id.

This is the code how it looked in the moment of writing this answer (it can, and probably will be changed in future):

"user":{"username":"...","profile_picture":"...","id":"..........","full_name":"..."}},

Description and examples can be found in IEEE Std 1800-2017 § 11.5.1 "Vector bit-select and part-select addressing". First IEEE appearance is IEEE 1364-2001 (Verilog) § 4.2.1 "Vector bit-select and part-select addressing". Here is an direct example from the LRM:

logic [31: 0] a_vect;
logic [0 :31] b_vect;
logic [63: 0] dword;
integer sel;
a_vect[ 0 +: 8] // == a_vect[ 7 : 0]
a_vect[15 -: 8] // == a_vect[15 : 8]
b_vect[ 0 +: 8] // == b_vect[0 : 7]
b_vect[15 -: 8] // == b_vect[8 :15]
dword[8*sel +: 8] // variable part-select with fixed width

If sel is 0 then dword[8*(0) +: 8] == dword[7:0]
If sel is 7 then dword[8*(7) +: 8] == dword[63:56]

The value to the left always the starting index. The number to the right is the width and must be a positive constant. the + and - indicates to select the bits of a higher or lower index value then the starting index.

Assuming address is in little endian ([msb:lsb]) format, then if(address[2*pointer+:2]) is the equivalent of if({address[2*pointer+1],address[2*pointer]})

You want to use absolute positioning.

An absolute position element is positioned relative to the first parent element that has a position other than static. If no such element is found, the containing block is html

For instance :

.yourDiv{
  position:absolute;
  top: 123px;
}

To get it to work, the parent needs to be relative (position:relative)

In your case this should do the trick:

.suggestionsBox{position:absolute; top:40px;}
#specific_locations_add{position:relative;}
