This issue could be because of wrong entity framework reference or sometimes the Class name not matching the entity name in database. Make sure the Table name matches with class name.

You have to use this in your MainActivity

 Intent intent = new Intent(context , yourActivity);

            intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK |Intent.FLAG_ACTIVITY_MULTIPLE_TASK);
            context.startActivity(intent);

The flag will start multiple tasks that will keep your MainActivity, when you call finish it will kill the other activity and get you back to the MainActivity

I just accomplished the opposite of this using :after and ::after because I needed to make my bottom border exactly 1.3rem wider:

My element got super deformed when I used :before and :after at the same time because the elements are horizontally aligned with display: flex, flex-direction: row and align-items: center.

You could use this for making something wider or narrower, or probably any mathematical dimension mods:

a.nav_link-active {
  color: $e1-red;
  margin-top: 3.7rem;
}
a.nav_link-active:visited {
  color: $e1-red;
}
a.nav_link-active:after {
  content: '';
  margin-top: 3.3rem;      // margin and height should
  height: 0.4rem;          // add up to active link margin
  background: $e1-red;
  margin-left: -$nav-spacer-margin;
  display: block;
}
a.nav_link-active::after {
  content: '';
  margin-top: 3.3rem;      // margin and height should
  height: 0.4rem;          // add up to active link margin
  background: $e1-red;
  margin-right: -$nav-spacer-margin;
  display: block;
}

Sorry, this is SCSS, just multiply the numbers by 10 and change the variables with some normal values.

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

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

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

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

Make a class that extends DialogFragment:

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

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

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

Then call it when you need it in your activity:

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

The delete operator allows you to remove a property from an object.

The following examples all do the same thing.

// Example 1
var key = "Cow";
delete thisIsObject[key]; 

// Example 2
delete thisIsObject["Cow"];

// Example 3
delete thisIsObject.Cow;

If you're interested, read Understanding Delete for an in-depth explanation.

Yes you can do it yourself. It is just a matter of grabbing the sources of the page and parsing them the way you want.

There are various possibilities. A good combo is using python-requests (built on top of urllib2, it is urllib.request in Python3) and BeautifulSoup4, which has its methods to select elements and also permits CSS selectors:

import requests
from BeautifulSoup4 import BeautifulSoup as bs
request = requests.get("http://foo.bar")
soup = bs(request.text) 
some_elements = soup.find_all("div", class_="myCssClass")

Some will prefer xpath parsing or jquery-like pyquery, lxml or something else.

When the data you want is produced by some JavaScript, the above won't work. You either need python-ghost or Selenium. I prefer the latter combined with PhantomJS, much lighter and simpler to install, and easy to use:

from selenium import webdriver
client = webdriver.PhantomJS()
client.get("http://foo")
soup = bs(client.page_source)

I would advice to start your own solution. You'll understand Scrapy's benefits doing so.

ps: take a look at scrapely: https://github.com/scrapy/scrapely

pps: take a look at Portia, to start extracting information visually, without programming knowledge: https://github.com/scrapinghub/portia

You could skip the jquery and just use CSS style tagging:

 <ul>
 <li>India</li>
 <li>Indonesia</li>
 <li style="background-color:#343434;">China</li>
 <li>United States</li>
 <li>United Kingdom</li>
 </ul>

You can find the number of members in a Javascript array by using its length property:

var number = $scope.names.length;

^{Docs - Array.prototype.length}

Assuming your sequence alternates increments between 1 and 3

numbers = [1]
while numbers[-1] < 100:
    numbers.append(numbers[-1] + 1)
    numbers.append(numbers[-1] + 3)

print ', '.join(map(str, numbers))

This could be easier to modify if your sequence is different but I think poke or BlaXpirit are nicer answers than mine.

The picture you showd in the question is actually a chart made using JavaScript. It is actually very easy to plot multi-axis chart using JavaScript with the help of 3rd party libraries like HighChart.js or D3.js. Here I propose to use the Funfun Excel add-in which allows you to use JavaScript directly in Excel so you could plot chart like you've showed easily in Excel. Here I made an example using Funfun in Excel.

You could see in this chart you have one axis of Rainfall at the left side while two axis of Temperature and Sea-pressure level at the right side. This is also a combination of line chart and bar chart for different datasets. In this example, with the help of the Funfun add-in, I used HighChart.js to plot this chart.

Funfun also has an online editor in which you could test your JavaScript code with you data. You could check the detailed code of this example on the link below.

https://www.funfun.io/1/#/edit/5a43b416b848f771fbcdee2c

Edit: The content on the previous link has been changed so I posted a new link here. The link below is the original link https://www.funfun.io/1/#/edit/5a55dc978dfd67466879eb24

If you are satisfied with the result you achieved in the online editor, you could easily load the result into you Excel using the URL above. Of couse first you need to insert the Funfun add-in from Insert - My add-ins. Here are some screenshots showing how you could do this.

Disclosure: I'm a developer of Funfun

After losing hours trying to find my error, the problem is your formula:

sigma = sum(y*(x-mean)**2)/n

This previous formula is wrong, the correct formula is the square root of this!;

sqrt(sum(y*(x-mean)**2)/n)

Hope this helps

import numpy as np

Colon does not have special meaning in a character class and does not need to be escaped. According to the PHP regex docs, the only characters that need to be escaped in a character class are the following:

All non-alphanumeric characters other than \, -, ^ (at the start) and the terminating ] are non-special in character classes, but it does no harm if they are escaped.

For more info about Java regular expressions, see the docs.

Put the textarea to a form, naming them, and just use the DOM objects easily, like this:

I seem to recall reading this article more than once, and the answer is only close to what I need.

Usually when I think I'm going to need a DO WHILE in T-SQL it's because I'm iterating a cursor, and I'm looking largely for optimal clarity (vs. optimal speed). In T-SQL that seems to fit a WHILE TRUE / IF BREAK.

If that's the scenario that brought you here, this snippet may save you a moment. Otherwise, welcome back, me. Now I can be certain I've been here more than once. :)

DECLARE Id INT, @Title VARCHAR(50)
DECLARE Iterator CURSOR FORWARD_ONLY FOR
SELECT Id, Title FROM dbo.SourceTable
OPEN Iterator
WHILE 1=1 BEGIN
    FETCH NEXT FROM @InputTable INTO @Id, @Title
    IF @@FETCH_STATUS < 0 BREAK
    PRINT 'Do something with ' + @Title
END
CLOSE Iterator
DEALLOCATE Iterator

Unfortunately, T-SQL doesn't seem to offer a cleaner way to singly-define the loop operation, than this infinite loop.

It may be possible that you have tried to run the npm start command in two different tabs .you cant run npm start when it is already running in some tab.check it once .

string uriPath =
    "file:\\C:\\Users\\john\\documents\\visual studio 2010\\Projects\\proj";
string localPath = new Uri(uriPath).LocalPath;

Name of the table and rows counter for all tables under OWNER schema:

SELECT table_name, num_rows counter from DBA_TABLES WHERE owner = 'OWNER'

You can map another entity based on this class (you should use entity-name in order to distinct the two) and the second one will be kind of dto (dont forget that dto has design issues ). you should define the second one as readonly and give it a good name in order to be clear that this is not a regular entity. by the way select only few columns is called projection , so google with it will be easier.

alternative - you can create named query with the list of fields that you need (you put them in the select ) or use criteria with projection

please escape your variables when outputting (urlencode).

and you can’t just print an array, you have to build your url using a loop in some way

$url = 'http://example.com/index.php?'
$first = true;
foreach($aValues as $key => $value) {
  if(!$first) $url .= '&amp';
  else $first = false;
  $url .= 'aValues['.urlencode($key).']='.urlencode($value);
}

Visio Professional has a database reverse-engineering feature if yiu create a database diagram. It's not free but is fairly ubiquitous in most companies and should be fairly easy to get.

Note that Visio 2003 does not play nicely with SQL2005 or SQL2008 for reverse engineering - you will need to get 2007.

In my case I was getting this message due to a runtime error with Junit which wasn't at all visible from the output of the gradle test task execution. I've run into this for a couple reasons:

1. Including the org.junit.platform:junit-platform-launcher dependency with a version that didn't match the junit version I was using
2. Having an entry in META-INF/services for a Junit test listener which I had commented out

You can try re-running with --debug and search for FAILED or org.gradle.api.internal.tasks.testing.TestSuiteExecutionException. In my second case, the exception was:

Notice that these are DEBUG logs. I didn't see anything helpful with just --info

Variables declared inside a function are local to that function. For instance:

foo <- function() {
    bar <- 1
}
foo()
bar

gives the following error: Error: object 'bar' not found.

If you want to make bar a global variable, you should do:

foo <- function() {
    bar <<- 1
}
foo()
bar

In this case bar is accessible from outside the function.

However, unlike C, C++ or many other languages, brackets do not determine the scope of variables. For instance, in the following code snippet:

if (x > 10) {
    y <- 0
}
else {
    y <- 1
}

y remains accessible after the if-else statement.

As you well say, you can also create nested environments. You can have a look at these two links for understanding how to use them:

1. http://stat.ethz.ch/R-manual/R-devel/library/base/html/environment.html
2. http://stat.ethz.ch/R-manual/R-devel/library/base/html/get.html

Here you have a small example:

test.env <- new.env()

assign('var', 100, envir=test.env)
# or simply
test.env$var <- 100

get('var') # var cannot be found since it is not defined in this environment
get('var', envir=test.env) # now it can be found

It's because there's no symlinks for libpng. You need to link libpng again.

brew unlink libpng && brew link libpng

And you may get some error. I fixed that error by correcting permission. Maybe it's because of uninstalled macports.

sudo chown -R yourid:staff /usr/local/share/man/

Create link again and it'll work.

The solution provided by Emanuele worked for me. I could see the report when I accessed it directly from the server but when I used a ReportViewer control on my aspx page, I was unable to see the report. Upon inspecting the rendered HTML, I found a div by the id "ReportViewerGeneral_ctl09" (ReportViewerGeneral is the server id of the report viewer control) which had it's overflow property set to auto.

<div id="ReportViewerGeneral_ctl09" style="height: 100%; width: 100%; overflow: auto; position: relative; ">...</div>

I used the procedure explained by Emanuele to change this to visible as follows:

function pageLoad() {
    var element = document.getElementById("ReportViewerGeneral_ctl09");

    if (element) {
        element.style.overflow = "visible";
    }
}

The issue here is that Map has two values (a key and value), while a List only has one value (an element).

Therefore, the best that can be done is to either get a List of the keys or the values. (Unless we make a wrapper to hold on to the key/value pair).

Say we have a Map:

Map<String, String> m = new HashMap<String, String>();
m.put("Hello", "World");
m.put("Apple", "3.14");
m.put("Another", "Element");

The keys as a List can be obtained by creating a new ArrayList from a Set returned by the Map.keySet method:

List<String> list = new ArrayList<String>(m.keySet());

While the values as a List can be obtained creating a new ArrayList from a Collection returned by the Map.values method:

List<String> list = new ArrayList<String>(m.values());

The result of getting the List of keys:

Apple
Another
Hello

The result of getting the List of values:

3.14
Element
World

Here's how to do it:

var myVideo = document.getElementById("my-video")    
myVideo.controls = false;

// Example data
DataTable table = new DataTable();
table.Columns.AddRange(new[]{ new DataColumn("Key"), new DataColumn("Value") });
foreach (string name in Request.ServerVariables)
    table.Rows.Add(name, Request.ServerVariables[name]);

This arstechnica article describes the basic steps:

Start by visiting the program portal and make sure that your developer certificate is up to date. It expires every six months and, if you haven't requested that a new one be issued, you cannot submit software to App Store. For most people experiencing the "pink upload of doom," though, their certificates are already valid. What next?

Open your Xcode project and check that you've set the active SDK to one of the device choices, like Device - 2.2. Accidentally leaving the build settings to Simulator can be a big reason for the pink rejection. And that happens more often than many developers would care to admit.

Next, make sure that you've chosen a build configuration that uses your distribution (not your developer) certificate. Check this by double-clicking on your target in the Groups & Files column on the left of the project window. The Target Info window will open. Click the Build tab and review your Code Signing Identity. It should be iPhone Distribution: followed by your name or company name.

You may also want to confirm your application identifier in the Properties tab. Most likely, you'll have set the identifier properly when debugging with your developer certificate, but it never hurts to check.

The top-left of your project window also confirms your settings and configuration. It should read something like "Device - 2.2 | Distribution". This shows you the active SDK and configuration.

If your settings are correct but you still aren't getting that upload finished properly, clean your builds. Choose Build > Clean (Command-Shift-K) and click Clean. Alternatively, you can manually trash the build folder in your Project from Finder. Once you've cleaned, build again fresh.

If this does not produce an app that when zipped properly loads to iTunes Connect, quit and relaunch Xcode. I'm not kidding. This one simple trick solves more signing problems and "pink rejections of doom" than any other solution already mentioned.

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.

A moving average can also be calculated and visualized directly in a line chart by using the following code:

Example using stock price data:

import pandas_datareader.data as web
import matplotlib.pyplot as plt
import datetime
plt.style.use('ggplot')

# Input variables
start = datetime.datetime(2016, 1, 01)
end = datetime.datetime(2018, 3, 29)
stock = 'WFC'

# Extrating data
df = web.DataReader(stock,'morningstar', start, end)
df = df['Close']

print df 

plt.plot(df['WFC'],label= 'Close')
plt.plot(df['WFC'].rolling(9).mean(),label= 'MA 9 days')
plt.plot(df['WFC'].rolling(21).mean(),label= 'MA 21 days')
plt.legend(loc='best')
plt.title('Wells Fargo\nClose and Moving Averages')
plt.show()

You can make use of JSON.Net here. Take a look at JsonConvert.DeserializeObject method.

There is no forumula, as street names and cities are essentially handed out randomly. The address needs to be looked up in a database. Alternatively, you can look up a zip code in a database for the region that the zip code is for.

You didn't mention a country, so I'm going to assume you just want addresses in the USA. There are numerous databases you can use, some free, some not.

You can also use the Google Maps API to have them look up an address in their database for you. That is probably the easiest solution, but requires your application to have a working internet connection at all times.

iframe{
  max-width: 100% !important;
}

To center more than one column in a Bootstrap row - and the number of cols are odd, simply add this css class to all the columns in that row:

.many-cols-centered {  // To horizontally center bootstrap odd cols, eg col-lg-9, col-md-3, works well in lg
  display:inline-block;
  float:none;
}

So in your HTML you have something like:

<div class="row text-center"> <!-- text-center centers all text in that row -->
    <div class="col-lg-3 col-md-3 col-sm-3 col-xs-12 many-cols-centered">
        <img src='assets/image1.jpg'>
        <h3>You See</h3>
        <p>I love coding.</p>
    </div>
    <div class="col-lg-3 col-md-3 col-sm-3 col-xs-12 many-cols-centered">
        <img src='assets/image2.jpg'>
        <h3>You See</h3>
        <p>I love coding.</p>
    </div>
    <div class="col-lg-3 col-md-3 col-sm-3 col-xs-12 many-cols-centered">
        <img src='assets/image3.jpg'>
        <h3>You See</h3>
        <p>I love coding.</p>
    </div>
</div>

In your Terminal run ipython:

ipython

then locate your script and put there:

%run your_script.ipynb

iOS Status bar has only 2 options (black and white). You can try this in AppDelegate:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{
    [[UIApplication sharedApplication] setStatusBarStyle: UIStatusBarStyleLightContent];
}

Short Answer

Remove the newline/linefeed characters (\n with Notepad++). Excel will still recognise the carriage return character (\r) to separate records.

Long Answer

As mentioned newline characters are supported inside CSV fields but Excel doesn't always handle them gracefully. I faced a similar issue with a third party CSV that possibly had encoding issues but didn't improve with encoding changes.

What worked for me was removing all newline characters (\n). This has the effect of collapsing fields to a single record assuming that your records are separated by the combination of a carriage return and a newline (CR/LF). Excel will then properly import the file and recognise new records by the carriage return.

Obviously a cleaner solution is to first replace the real newlines (\r\n) with a temporary character combination, replacing the newlines (\n) with your seperating character of choice (e.g. comma in a semicolon file) and then replacing the temporary characters with proper newlines again.

This is an older post but I want to also mention that if you have something like

insert into blah
       select * from blah2

and blah and blah2 are identical keep in mind that a computed column will throw this same error...

I just realized that when the above failed and I tried

insert into blah (cola, colb, colc)
       select cola, colb, colc from blah2

In my example it was fullname field (computed from first and last, etc)

You can trigger any of the events with a direct call to them, like this:

$(function() {
    $('item').keydown();
    $('item').keypress();
    $('item').keyup();
    $('item').blur();
});

Does that do what you're trying to do?

You should probably also trigger .focus() and potentially .change()

If you want to trigger the key-events with specific keys, you can do so like this:

$(function() {
    var e = $.Event('keypress');
    e.which = 65; // Character 'A'
    $('item').trigger(e);
});

There is some interesting discussion of the keypress events here: jQuery Event Keypress: Which key was pressed?, specifically regarding cross-browser compatability with the .which property.

The easiest is Simple there is a tutorial, no WEB-INF not Servlet API no dependencies. Just a simple lightweight HTTP server in a single JAR.

If you are using python3 on windows then you might do this as well

pip3 install tensorflow==1.4

you may select any version from "(from versions: 1.2.0rc2, 1.2.0, 1.2.1, 1.3.0rc0, 1.3.0rc1, 1.3.0rc2, 1.3.0, 1.4.0rc0, 1.4.0rc1, 1.4.0, 1.5.0rc0, 1.5.0rc1, 1.5.0, 1.5.1, 1.6.0rc0, 1.6.0rc1, 1.6.0, 1.7.0rc0, 1.7.0rc1, 1.7.0)"

I did this when I wanted to downgrade from 1.7 to 1.4

POCO stands for "Plain Old CLR Object".

This code will store the image in database.

$('#image').change(function(){
        // FileReader function for read the file.
        let reader = new FileReader();
        var base64;
        reader.readAsDataURL(this.files[0]); 

        //Read File
        let filereader = new FileReader();
        var selectedFile = this.files[0];

        // Onload of file read the file content
        filereader.onload = function(fileLoadedEvent) {
            base64 = fileLoadedEvent.target.result;
            $("#pimage").val(JSON.stringify(base64));
        };

        filereader.readAsDataURL(selectedFile); 
 });

HTML content should be like this.

<div class="col-xs-12 col-sm-4 col-md-4 user_frm form-group">
        <input id="image" type="file" class="inputMaterial" name="image">        
        <input type="hidden" id="pimage" name="pimage" value="">
        <span class="bar"></span>
    </div>

Store image data in database like this:

//property_image longtext(database field type)

 $data= array(
      'property_image' => trim($request->get('pimage'),'"')
 );

Display image:

<img src="{{$result->property_image}}" >

Yes, you can do this. The knack you need is the concept that there are two ways of getting tables out of the table server. One way is ..

FROM TABLE A

The other way is

FROM (SELECT col as name1, col2 as name2 FROM ...) B

Notice that the select clause and the parentheses around it are a table, a virtual table.

So, using your second code example (I am guessing at the columns you are hoping to retrieve here):

SELECT a.attr, b.id, b.trans, b.lang
FROM attribute a
JOIN (
 SELECT at.id AS id, at.translation AS trans, at.language AS lang, a.attribute
 FROM attributeTranslation at
) b ON (a.id = b.attribute AND b.lang = 1)

Notice that your real table attribute is the first table in this join, and that this virtual table I've called b is the second table.

This technique comes in especially handy when the virtual table is a summary table of some kind. e.g.

SELECT a.attr, b.id, b.trans, b.lang, c.langcount
FROM attribute a
JOIN (
 SELECT at.id AS id, at.translation AS trans, at.language AS lang, at.attribute
 FROM attributeTranslation at
) b ON (a.id = b.attribute AND b.lang = 1)
JOIN (
 SELECT count(*) AS langcount,  at.attribute
 FROM attributeTranslation at
 GROUP BY at.attribute
) c ON (a.id = c.attribute)

See how that goes? You've generated a virtual table c containing two columns, joined it to the other two, used one of the columns for the ON clause, and returned the other as a column in your result set.

Dockers use images which are build in layers. This adds a lot in terms of portability, sharing, versioning and other features. These images are very easy to port or transfer and since they are in layers, changes in subsequent versions are added in form of layers over previous layers. So, while porting many a times you don't need to port the base layers. Dockers have containers which run these images with execution environment contained, they add changes as new layers providing easy version control.

Apart from that Docker Hub is a good registry with thousands of public images, where you can find images which have OS and other softwares installed. So, you can get a pretty good head start for your application.

If you really want to create an array rather than a list use either

String[] names = ["lucas", "Fred", "Mary"]

or

def names = ["lucas", "Fred", "Mary"].toArray()

You can use the array_key_exists() built-in function:

if (array_key_exists('id', $_GET)) {
    echo $_GET['id'];
}

or the isset() built-in function:

if (isset($_GET['id'])) {
    echo $_GET['id'];
}

The trick is to give padding on the td elements, but make an exception for the first (yes, it's hacky, but sometimes you have to play by the browser's rules):

td {
  padding-top:20px;
  padding-bottom:20px;
  padding-right:20px;   
}

td:first-child {
  padding-left:20px;
  padding-right:0;
}

First-child is relatively well supported: https://developer.mozilla.org/en-US/docs/CSS/:first-child

You can use the same reasoning for the horizontal padding by using tr:first-child td.

Alternatively, exclude the first column by using the not operator. Support for this is not as good right now, though.

td:not(:first-child) {
  padding-top:20px;
  padding-bottom:20px;
  padding-right:20px;       
}

I've created this tool years ago for the same purpose:
http://www.betterprogramming.com/htmlclipper.html

You're welcome to use and improve upon it.

@andyb's accepted answer has a small bug. Further to my comment on his post above...

For this HTML:

<div id="foo" data-helptext="bar"></div>
<a href="#" id="changeData">change data value</a>

You need to access the attribute like this:

$('#foo').attr('data-helptext', 'Testing 123');

but the data method like this:

$('#foo').data('helptext', 'Testing 123');

The fix above for the .data() method will prevent "undefined" and the data value will be updated (while the HTML will not)

The point of the "data" attribute is to bind (or "link") a value with the element. Very similar to the onclick="alert('do_something')" attribute, which binds an action to the element... the text is useless you just want the action to work when they click the element.

Once the data or action is bound to the element, there is usually* no need to update the HTML, only the data or method, since that is what your application (JavaScript) would use. Performance wise, I don't see why you would want to also update the HTML anyway, no one sees the html attribute (except in Firebug or other consoles).

One way you might want to think about it: The HTML (along with attributes) are just text. The data, functions, objects, etc that are used by JavaScript exist on a separate plane. Only when JavaScript is instructed to do so, it will read or update the HTML text, but all the data and functionality you create with JavaScript are acting completely separate from the HTML text/attributes you see in your Firebug (or other) console.

*I put emphasis on usually because if you have a case where you need to preserve and export HTML (e.g. some kind of micro format/data aware text editor) where the HTML will load fresh on another page, then maybe you need the HTML updated too.

Sometimes using   instead of spaces will work. Clearly it has drawbacks, though.

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.

I also was not happy with the Internet checking options available (Why is this not a native API?!?!)

My own issue was with 100% packet loss -- when a device is connected to the router, but the router is not connected to the Internet. Reachability and others will hang for ages. I created a utility singleton class to deal with that by adding an asynch time-out. It works fine in my app. Hope it helps. Here's the link on github:

https://github.com/fareast555/TFInternetChecker

The document.createEvent documentation says that "The createEvent method is deprecated. Use event constructors instead."

So you should use this method instead:

var clickEvent = new MouseEvent("click", {
    "view": window,
    "bubbles": true,
    "cancelable": false
});

and fire it on an element like this:

element.dispatchEvent(clickEvent);

as shown here.

On Linux, macOS and Unix to display the groups to which you belong, use:

id -Gn

which is equivalent to groups utility which has been obsoleted on Unix (as per Unix manual).

On macOS and Unix, the command id -p is suggested for normal interactive.

Explanation of the parameters:

-G, --groups - print all group IDs

-n, --name - print a name instead of a number, for -ugG

-p - Make the output human-readable.

Something like this might work for you:

"UPDATE myTable SET ... ;
 UPDATE myTable SET ... ;
 UPDATE myTable SET ... ;
 UPDATE myTable SET ... ;"

If any of the posX or posY values are the same, then they could be combined into one query

UPDATE myTable SET posX='39' WHERE id IN('2','3','40');

Here's a bash function which checks all your servers, assuming you're using DNS round-robin. Note that this requires GNU date and won't work on Mac OS

function check_certs () {
  if [ -z "$1" ]
  then
    echo "domain name missing"
    exit 1
  fi
  name="$1"
  shift

  now_epoch=$( date +%s )

  dig +noall +answer $name | while read _ _ _ _ ip;
  do
    echo -n "$ip:"
    expiry_date=$( echo | openssl s_client -showcerts -servername $name -connect $ip:443 2>/dev/null | openssl x509 -inform pem -noout -enddate | cut -d "=" -f 2 )
    echo -n " $expiry_date";
    expiry_epoch=$( date -d "$expiry_date" +%s )
    expiry_days="$(( ($expiry_epoch - $now_epoch) / (3600 * 24) ))"
    echo "    $expiry_days days"
  done
}

Output example:

$ check_certs stackoverflow.com
151.101.1.69: Aug 14 12:00:00 2019 GMT    603 days
151.101.65.69: Aug 14 12:00:00 2019 GMT    603 days
151.101.129.69: Aug 14 12:00:00 2019 GMT    603 days
151.101.193.69: Aug 14 12:00:00 2019 GMT    603 days

After close examining, not 300k lines but there are around 3-4 CSS properties that you need to override:

.navbar-collapse.collapse {
  display: block!important;
}

.navbar-nav>li, .navbar-nav {
  float: left !important;
}

.navbar-nav.navbar-right:last-child {
  margin-right: -15px !important;
}

.navbar-right {
  float: right!important;
}

And with this your menu won't collapse.

DEMO (jsfiddle)

EXPLANATION

The four CSS properties do the respective:

1. The default .collapse property in bootstrap hides the right-side of the menu for tablets(landscape) and phones and instead a toggle button is displayed to hide/show it. Thus this property overrides the default and persistently shows those elements.

2. For the right-side menu to appear on the same line along with the left-side, we need the left-side to be floating left.

3. This property is present by default in bootstrap but not on tablet(portrait) to phone resolution. You can skip this one, it's likely to not affect your overall navbar.

4. This keeps the right-side menu to the right while the inner elements (li) will follow the property 2. So we have left-side float left and right-side float right which brings them into one line.

using Boost.Locale:

ws = boost::locale::conv::utf_to_utf<wchar_t>(s);

Javascript won't execute within a value attribute. You could do something like this, though:

<input id="date" name="date">

<script type="text/javascript">
  document.getElementById('date').value = Date();
</script>

You'd probably want to format the date as you prefer, because the default output of Date() looks something like: Tue Jun 16 2009 10:47:10 GMT-0400 (Eastern Daylight Time). See this SO question for info about formatting a date.

There is a version conflict between jar/dependency please check all version of spring is same. if you use maven remove version of dependency and use Spring.io dependency.it handle version conflict. Add this in your pom

 <dependency>
            <groupId>io.spring.platform</groupId>
            <artifactId>platform-bom</artifactId>
            <version>2.0.1.RELEASE</version>
            <type>pom</type>
            <scope>import</scope>
  </dependency>

If you facing grant permission access denied problem, you can try mysql to fix the problem:

grant all privileges on . to root@'localhost' identified by 'Your password';

grant all privileges on . to root@'IP ADDRESS' identified by 'Your password?';

your can try this on any mysql user, its working.

Use below command to login mysql with iP address.

mysql -h 10.0.0.23 -u root -p

By default git revert refuses to revert a merge commit as what that actually means is ambiguous. I presume that your HEAD is in fact a merge commit.

If you want to revert the merge commit, you have to specify which parent of the merge you want to consider to be the main trunk, i.e. what you want to revert to.

Often this will be parent number one, for example if you were on master and did git merge unwanted and then decided to revert the merge of unwanted. The first parent would be your pre-merge master branch and the second parent would be the tip of unwanted.

In this case you could do:

git revert -m 1 HEAD

You might get this error message if you've just installed the phpmyadmin package but haven't restarted apache yet; try restarting apache.

In the code given in the question, I think that reading the ExitCode property of the initiation variable should work.

$process = Start-Process -FilePath ping -ArgumentList localhost -NoNewWindow -PassThru -Wait
$process.ExitCode

Note that (as in your example) you need to add the -PassThru and -Wait parameters (this caught me out for a while).

This is what css is for... HTML doesn't allow for unequal padding. When you say that you don't want to use style sheets, does this mean you're OK with inline css?

<table>
    <tr>
        <td style="padding: 5px 10px 5px 5px;">Content</td>
        <td style="padding: 5px 10px 5px 5px;">Content</td>
    </tr>
</table>

You could also use JS to do this if you're desperate not to use stylesheets for some reason.

I know this is an old question but you can use:

array_push($data, array($category => $question));

This will push the array onto the end of your current array. Or if you are just trying to add single values to the end of your array, not more arrays then you can use this:

array_push($data,$question);

Here is a cross platform solution to clearing docker container logs:

docker run --rm -v /var/lib/docker:/var/lib/docker alpine sh -c "echo '' > $(docker inspect --format='{{.LogPath}}' CONTAINER_NAME)"

Paste this into your terminal and change CONTAINER_NAME to desired container name or id.

You did not add # before id of the button. You do not have right selector in your jquery code. So jquery is never execute in your button click. its submitted your form directly not passing any ajax request.

See documentation: http://api.jquery.com/category/selectors/
its your friend.

Try this:

It seems that id: $("#Shareitem").val() is wrong if you want to pass the value of

<input type="hidden" name="id" value="" id="id">

you need to change this line:

id: $("#Shareitem").val()

by

id: $("#id").val()

All together:

 <script src="http://code.jquery.com/jquery-1.11.0.min.js"></script>
    <script>
    $(document).ready(function(){
      $("#Shareitem").click(function(e){
          e.preventDefault();
        $.ajax({type: "POST",
                url: "/imball-reagens/public/shareitem",
                data: { id: $("#Shareitem").val(), access_token: $("#access_token").val() },
                success:function(result){
          $("#sharelink").html(result);
        }});
      });
    });
    </script>

The second for loop is any easy way to iterate over the contents of an array, without having to manually specify the number of items in the array(manual enumeration). It is much more convenient than the first when dealing with arrays.

put public, protected or private before the $connection.

Approach: 1

Given original string format: 2019/03/04 00:08:48

you can use

updated_df = df['timestamp'].astype('datetime64[ns]')

The result will be in this datetime format: 2019-03-04 00:08:48

Approach: 2

updated_df = df.astype({'timestamp':'datetime64[ns]'})

Two memory efficient ways in ranked order (first is best) -

1. use of with - supported from python 2.5 and above
2. use of yield if you really want to have control over how much to read

1. use of with

with is the nice and efficient pythonic way to read large files. advantages - 1) file object is automatically closed after exiting from with execution block. 2) exception handling inside the with block. 3) memory for loop iterates through the f file object line by line. internally it does buffered IO (to optimized on costly IO operations) and memory management.

with open("x.txt") as f:
    for line in f:
        do something with data

2. use of yield

Sometimes one might want more fine-grained control over how much to read in each iteration. In that case use iter & yield. Note with this method one explicitly needs close the file at the end.

def readInChunks(fileObj, chunkSize=2048):
    """
    Lazy function to read a file piece by piece.
    Default chunk size: 2kB.

    """
    while True:
        data = fileObj.read(chunkSize)
        if not data:
            break
        yield data

f = open('bigFile')
for chunk in readInChunks(f):
    do_something(chunk)
f.close()

Pitfalls and for the sake of completeness - below methods are not as good or not as elegant for reading large files but please read to get rounded understanding.

In Python, the most common way to read lines from a file is to do the following:

for line in open('myfile','r').readlines():
    do_something(line)

When this is done, however, the readlines() function (same applies for read() function) loads the entire file into memory, then iterates over it. A slightly better approach (the first mentioned two methods above are the best) for large files is to use the fileinput module, as follows:

import fileinput

for line in fileinput.input(['myfile']):
    do_something(line)

the fileinput.input() call reads lines sequentially, but doesn't keep them in memory after they've been read or even simply so this, since file in python is iterable.

I think that what you have to check is:

1. if the target EXE is correctly configured in the project settings ("command", in the debugging tab). Since all individual projects run when you start debugging it's well possible that only the debugging target for the "ALL" solution is missing, check which project is currently active (you can also select the debugger target by changing the active project).

2. dependencies (DLLs) are also located at the target debugee directory or can be loaded (you can use the "depends.exe" tool for checking dependencies of an executable or DLL).

It might be the JavaScript check for some valid condition.
Two things you can perform a/c to your requirements:

1. either check for the valid string-input in the text-box.
2. or set a loop against that text box to enter the value until you post the form/request.

String barcode="0000000047166";

WebElement strLocator = driver.findElement(By.xpath("//*[@id='div-barcode']"));
strLocator.sendKeys(barcode);

Please run the below query, it doesn't requires STUFF and GROUP BY in your case:

Select
      A.maskid
    , A.maskname
    , A.schoolid
    , B.schoolname
    , CAST((
          SELECT  T.maskdetail+','
          FROM dbo.maskdetails T
          WHERE A.maskid = T.maskid
          FOR XML PATH(''))as varchar(max)) as maskdetail 
FROM dbo.tblmask A
JOIN dbo.school B ON B.ID = A.schoolid

As @huyz mention sometimes desired behavior is using case-insensitive searches but case-sensitive substitutions. My solution for that:

nnoremap / /\c
nnoremap ? ?\c

With that always when you hit / or ? it will add \c for case-insensitive search.

Documentation can be found e.g. at MDN. Note that .split() is not a jQuery method, but a native string method.

If you use .split() on a string, then you get an array back with the substrings:

var str = 'something -- something_else';
var substr = str.split(' -- ');
// substr[0] contains "something"
// substr[1] contains "something_else"

If this value is in some field you could also do:

tRow.append($('<td>').text($('[id$=txtEntry2]').val().split(' -- ')[0])));

Use req.query, for getting he value in query string parameter in the route. Refer req.query. Say if in a route, http://localhost:3000/?name=satyam you want to get value for name parameter, then your 'Get' route handler will go like this :-

app.get('/', function(req, res){
    console.log(req.query.name);
    res.send('Response send to client::'+req.query.name);

});

You can use Apache commons-lang

StringUtils.isEmpty(String str) - Checks if a String is empty ("") or null.

or

StringUtils.isBlank(String str) - Checks if a String is whitespace, empty ("") or null.

the latter considers a String which consists of spaces or special characters eg " " empty too. See java.lang.Character.isWhitespace API

Use MethodInvoker for updating label text in other thread.

private void AggiornaContatore()
{
    MethodInvoker inv = delegate 
    {
      this.lblCounter.Text = this.index.ToString(); 
    }

 this.Invoke(inv);
}

You are getting the error because your UI thread is holding the label, and since you are trying to update it through another thread you are getting cross thread exception.

If you didn't want to use async/await inside your method, but still "decorate" it so as to be able to use the await keyword from outside, TaskCompletionSource.cs:

public static Task<T> RunAsync<T>(Func<T> function)
{ 
    if (function == null) throw new ArgumentNullException(“function”); 
    var tcs = new TaskCompletionSource<T>(); 
    ThreadPool.QueueUserWorkItem(_ =>          
    { 
        try 
        {  
           T result = function(); 
           tcs.SetResult(result);  
        } 
        catch(Exception exc) { tcs.SetException(exc); } 
   }); 
   return tcs.Task; 
}

From here and here

To support such a paradigm with Tasks, we need a way to retain the Task façade and the ability to refer to an arbitrary asynchronous operation as a Task, but to control the lifetime of that Task according to the rules of the underlying infrastructure that’s providing the asynchrony, and to do so in a manner that doesn’t cost significantly. This is the purpose of TaskCompletionSource.

I saw it's also used in the .NET source, e.g. WebClient.cs:

    [HostProtection(ExternalThreading = true)]
    [ComVisible(false)]
    public Task<string> UploadStringTaskAsync(Uri address, string method, string data)
    {
        // Create the task to be returned
        var tcs = new TaskCompletionSource<string>(address);

        // Setup the callback event handler
        UploadStringCompletedEventHandler handler = null;
        handler = (sender, e) => HandleCompletion(tcs, e, (args) => args.Result, handler, (webClient, completion) => webClient.UploadStringCompleted -= completion);
        this.UploadStringCompleted += handler;

        // Start the async operation.
        try { this.UploadStringAsync(address, method, data, tcs); }
        catch
        {
            this.UploadStringCompleted -= handler;
            throw;
        }

        // Return the task that represents the async operation
        return tcs.Task;
    }

Finally, I also found the following useful:

I get asked this question all the time. The implication is that there must be some thread somewhere that’s blocking on the I/O call to the external resource. So, asynchronous code frees up the request thread, but only at the expense of another thread elsewhere in the system, right? No, not at all.

To understand why asynchronous requests scale, I’ll trace a (simplified) example of an asynchronous I/O call. Let’s say a request needs to write to a file. The request thread calls the asynchronous write method. WriteAsync is implemented by the Base Class Library (BCL), and uses completion ports for its asynchronous I/O. So, the WriteAsync call is passed down to the OS as an asynchronous file write. The OS then communicates with the driver stack, passing along the data to write in an I/O request packet (IRP).

This is where things get interesting: If a device driver can’t handle an IRP immediately, it must handle it asynchronously. So, the driver tells the disk to start writing and returns a “pending” response to the OS. The OS passes that “pending” response to the BCL, and the BCL returns an incomplete task to the request-handling code. The request-handling code awaits the task, which returns an incomplete task from that method and so on. Finally, the request-handling code ends up returning an incomplete task to ASP.NET, and the request thread is freed to return to the thread pool.

Introduction to Async/Await on ASP.NET

If the target is to improve scalability (rather than responsiveness), it all relies on the existence of an external I/O that provides the opportunity to do that.

This is my summary of the above and works perfectly for me. Thanks for the info!

The response by @Miknash and @wolfgang gutierrez barrera was helpful to me. Only difference was I had to add rgbValue: to the function call.

UIColorFromHex(rgbValue: 0xA6D632,alpha: 1 ) like so

My reason for researching this question was from the perspective, is in what way are they compatible. Latin1 charset (iso-8859) is 100% compatible to be stored in a utf8 datastore. All ascii & extended-ascii chars will be stored as single-byte.

Going the other way, from utf8 to Latin1 charset may or may not work. If there are any 2-byte chars (chars beyond extended-ascii 255) they will not store in a Latin1 datastore.

Here is a quick console app to depict the concept of how to solve your issue.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication3
{
    public class myobj
    {
        private string a = string.Empty;
        private string b = string.Empty;

        public myobj(string a, string b)
        {
            this.a = a;
            this.b = b;
        }

        public string A
        {
            get
            {
                return a;
            }
        }

        public string B
        {
            get
            {
                return b;
            }
        }
    }


    class Program
    {
        static void Main(string[] args)
        {
            List<myobj> list = new List<myobj>();
            myobj[] objects = { new myobj("a", "b"), new myobj("c", "d"), new myobj("a", "b") };


            for (int i = 0; i < objects.Length; i++)
            {
                if (!list.Exists((delegate(myobj x) { return (string.Equals(x.A, objects[i].A) && string.Equals(x.B, objects[i].B)) ? true : false; })))
                {
                    list.Add(objects[i]);
                }
            }
        }
    }
}

Enjoy!

In the case of nested tables, some DBMS require to use an alias like MySQL and Oracle but others do not have such a strict requirement, but still allow to add them to substitute the result of the inner query.

Another fairly simple way to go about this is to make a method like this:

def _write_frame_to_new_sheet(path_to_file=None, sheet_name='sheet', data_frame=None):
    book = None
    try:
        book = load_workbook(path_to_file)
    except Exception:
        logging.debug('Creating new workbook at %s', path_to_file)
    with pd.ExcelWriter(path_to_file, engine='openpyxl') as writer:
        if book is not None:
            writer.book = book
        data_frame.to_excel(writer, sheet_name, index=False)

The idea here is to load the workbook at path_to_file if it exists and then append the data_frame as a new sheet with sheet_name. If the workbook does not exist, it is created. It seems that neither openpyxl or xlsxwriter append, so as in the example by @Stefano above, you really have to load and then rewrite to append.

How to change max_connections

You can change max_connections while MySQL is running via SET:

mysql> SET GLOBAL max_connections = 5000;
Query OK, 0 rows affected (0.00 sec)

mysql> SHOW VARIABLES LIKE "max_connections";
+-----------------+-------+
| Variable_name   | Value |
+-----------------+-------+
| max_connections | 5000  |
+-----------------+-------+
1 row in set (0.00 sec)

To OP

timeout related

I had never seen your error message before, so I googled. probably, you are using Connector/Net. Connector/Net Manual says there is max connection pool size. (default is 100) see table 22.21.

I suggest that you increase this value to 100k or disable connection pooling Pooling=false

UPDATED

he has two questions.

Q1 - what happens if I disable pooling Slow down making DB connection. connection pooling is a mechanism that use already made DB connection. cost of Making new connection is high. http://en.wikipedia.org/wiki/Connection_pool

Q2 - Can the value of pooling be increased or the maximum is 100?

you can increase but I'm sure what is MAX value, maybe max_connections in my.cnf

My suggestion is that do not turn off Pooling, increase value by 100 until there is no connection error.

If you have Stress Test tool like JMeter you can test youself.

Have you given a try to Webkit Filters?

You can manipulate not only opacity, but colour, brightness, luminosity and other properties:

Take a look at Joda-Time (https://www.joda.org/joda-time/).

DateTimeFormatter parser = ISODateTimeFormat.date();

DateTime date = parser.parseDateTime(dateString);

String nextDay = parser.print(date.plusDays(1));

This worked perfectly with grouped calls: Implement a custom subclass of UITableViewCell

This will respect corners and such...

- (void)setSelected:(BOOL)selected animated:(BOOL)animated
{
    [super setSelected:selected animated:animated];

    if(selected)
        [self setBackgroundColor:[UIColor colorWithRed:(245/255.0) green:(255/255.0) blue:(255/255.0) alpha:1]];
    else
        [self setBackgroundColor:[UIColor whiteColor]];

}

create a new java project in Eclipse and copy .java files to its src directory, if you don't know where those source files should be placed, right click on the root of the project and choose new->class to create a test class and see where its .java file is placed, then put other files with it, in the same directory, you may have to adjust the package in those source files according to the new project directory structure.

if you use external libraries in your code, you have two options: either copy / download jar files or use maven if you use maven you'll have to create the project at maven project in the first place, creating java projects as maven projects are the way to go anyway but that's for another post...

It is correct that there is no work-around for this aside from ditching the select element, but if you only need to show more items in your select list you can simply use the size attribute:

<select multiple="multiple" size="15">
<option>1</option>
<option>2</option>
<option>3</option>
<option>4</option>
</select>

Doing this you'll have additional empty lines if your collection of items lenght is smaller than size value.

Try switching the theme in the design view to one of the options in "Manifest Themes". I'm guessing this is Because you are inheriting the theme from the manifest to support multiple api levels. It worked for me anyway.

Building on @nad2000's answer and @Pavel's answer here, this is where I ended up for my Flyway migration scripts. Handling for scenarios where the database schema was manually modified.

DO $$
BEGIN
    IF NOT EXISTS(
        SELECT TRUE FROM pg_attribute 
        WHERE attrelid = (
            SELECT c.oid
            FROM pg_class c
            JOIN pg_namespace n ON n.oid = c.relnamespace
            WHERE 
                n.nspname = CURRENT_SCHEMA() 
                AND c.relname = 'device_ip_lookups'
            )
        AND attname = 'active_date'
        AND NOT attisdropped
        AND attnum > 0
        )
    THEN
        RAISE NOTICE 'ADDING COLUMN';        
        ALTER TABLE device_ip_lookups
            ADD COLUMN active_date TIMESTAMP;
    ELSE
        RAISE NOTICE 'SKIPPING, COLUMN ALREADY EXISTS';
    END IF;
END $$;

printf() doesn't directly support that. Instead you have to make your own function.

Something like:

while (n) {
    if (n & 1)
        printf("1");
    else
        printf("0");

    n >>= 1;
}
printf("\n");

You can use the Jquery UI for drag and drop with an additional library that translates mouse events into touch which is what you need, the library I recommend is https://github.com/furf/jquery-ui-touch-punch, with this your drag and drop from Jquery UI should work on touch devises

or you can use this code which I am using, it also converts mouse events into touch and it works like magic.

function touchHandler(event) {
    var touch = event.changedTouches[0];

    var simulatedEvent = document.createEvent("MouseEvent");
        simulatedEvent.initMouseEvent({
        touchstart: "mousedown",
        touchmove: "mousemove",
        touchend: "mouseup"
    }[event.type], true, true, window, 1,
        touch.screenX, touch.screenY,
        touch.clientX, touch.clientY, false,
        false, false, false, 0, null);

    touch.target.dispatchEvent(simulatedEvent);
    event.preventDefault();
}

function init() {
    document.addEventListener("touchstart", touchHandler, true);
    document.addEventListener("touchmove", touchHandler, true);
    document.addEventListener("touchend", touchHandler, true);
    document.addEventListener("touchcancel", touchHandler, true);
}

And in your document.ready just call the init() function

Most of the answers show how to best handle HttpContext from the documentation, which is also what I went with.

I did want to mention that you'll want to check you project settings when debugging, the default is Enable Anonymous Authentication = true.

Try

java -cp .:mail-1.4.1.jar JavaxMailHTML 

no need to have manifest file.

Here is a solution that takes into account different ports and https:

$pageURL = (@$_SERVER['HTTPS'] == 'on') ? 'https://' : 'http://';

if ($_SERVER['SERVER_PORT'] != '80')
  $pageURL .= $_SERVER['SERVER_NAME'].':'.$_SERVER['SERVER_PORT'].$_SERVER['PHP_SELF'];
else 
  $pageURL .= $_SERVER['SERVER_NAME'].$_SERVER['PHP_SELF'];  

Or a more basic solution that does not take other ports into account:

$pageURL = (@$_SERVER['HTTPS'] == 'on') ? 'https://' : 'http://';
$pageURL .= $_SERVER['SERVER_NAME'].$_SERVER['PHP_SELF']; 

function setValToAssessment(id)
{

     $.getJSON("<?= URL.$param->module."/".$param->controller?>/setvalue",{id: id}, function(response)
     {
        var form = $('<form></form>').attr("id",'hiddenForm' ).attr("name", 'hiddenForm'); 
         $.each(response,function(key,value){
            $("<input type='text' value='"+value+"' >")
 .attr("id", key)
 .attr("name", key)
 .appendTo("form");


             });
              $('#hiddenForm').appendTo('body').submit();

        // window.location.href = "<?=URL.$param->module?>/assessment";
    });

}     

I had this issue, and solved by following:

Cause

There is a known bug with MySQL related to MyISAM, the UTF8 character set and indexes that you can check here.

Resolution

• Make sure MySQL is configured with the InnoDB storage engine.

• Change the storage engine used by default so that new tables will always be created appropriately:

  set GLOBAL storage_engine='InnoDb';

• For MySQL 5.6 and later, use the following:

  SET GLOBAL default_storage_engine = 'InnoDB';

• And finally make sure that you're following the instructions provided in Migrating to MySQL.

You'll need to write an insert trigger, and possible an update trigger if you want it to change when the record is changed. This article explains it quite nicely:

http://www.revsys.com/blog/2006/aug/04/automatically-updating-a-timestamp-column-in-postgresql/

CREATE OR REPLACE FUNCTION update_modified_column()   
RETURNS TRIGGER AS $$
BEGIN
    NEW.modified = now();
    RETURN NEW;   
END;
$$ language 'plpgsql';

Apply the trigger like this:

CREATE TRIGGER update_customer_modtime BEFORE UPDATE ON customer FOR EACH ROW EXECUTE PROCEDURE  update_modified_column();

Here is solution for dynamic queries.

For example if you have more tables with different suffix:

dbo.SOMETHINGTABLE_ONE, dbo.SOMETHINGTABLE_TWO

Code:

DECLARE @INDEX AS NVARCHAR(20)
DECLARE @CheckVALUE AS NVARCHAR(max) = 'SELECT COUNT(SOMETHING) FROM 
dbo.SOMETHINGTABLE_'+@INDEX+''
DECLARE @tempTable Table (TempVALUE int)
DECLARE @RESULTVAL INT

INSERT INTO @tempTable
    EXEC sp_executesql @CheckVALUE

SET @RESULTVAL = (SELECT * FROM @tempTable)

DELETE @tempTable

SELECT @RESULTVAL 

I have used Fredrik's code above in a project with some slight modifications, thought I'd share:

private static bool DownloadRemoteImageFile(string uri, string fileName)
{
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri);
    HttpWebResponse response;
    try
    {
        response = (HttpWebResponse)request.GetResponse();
    }
    catch (Exception)
    {
        return false;
    }

    // Check that the remote file was found. The ContentType
    // check is performed since a request for a non-existent
    // image file might be redirected to a 404-page, which would
    // yield the StatusCode "OK", even though the image was not
    // found.
    if ((response.StatusCode == HttpStatusCode.OK ||
        response.StatusCode == HttpStatusCode.Moved ||
        response.StatusCode == HttpStatusCode.Redirect) &&
        response.ContentType.StartsWith("image", StringComparison.OrdinalIgnoreCase))
    {

        // if the remote file was found, download it
        using (Stream inputStream = response.GetResponseStream())
        using (Stream outputStream = File.OpenWrite(fileName))
        {
            byte[] buffer = new byte[4096];
            int bytesRead;
            do
            {
                bytesRead = inputStream.Read(buffer, 0, buffer.Length);
                outputStream.Write(buffer, 0, bytesRead);
            } while (bytesRead != 0);
        }
        return true;
    }
    else
        return false;
}

Main changes are:

• using a try/catch for the GetResponse() as I was running into an exception when the remote file returned 404
• returning a boolean

Quick note: if you're also using coord_flip() to flip the x and the y axis, you won't be able to set range limits using coord_cartesian() because those two functions are exclusive (see here).

Fortunately, this is an easy fix; set your limits within coord_flip() like so:

p + coord_flip(ylim = c(3,5), xlim = c(100, 400))

This just alters the visible range (i.e. doesn't remove data points).

For me the UnicodeWriter class from Python 2 CSV module documentation didn't really work as it breaks the csv.writer.write_row() interface.

For example:

csv_writer = csv.writer(csv_file)
row = ['The meaning', 42]
csv_writer.writerow(row)

works, while:

csv_writer = UnicodeWriter(csv_file)
row = ['The meaning', 42]
csv_writer.writerow(row)

will throw AttributeError: 'int' object has no attribute 'encode'.

As UnicodeWriter obviously expects all column values to be strings, we can convert the values ourselves and just use the default CSV module:

def to_utf8(lst):
    return [unicode(elem).encode('utf-8') for elem in lst]

...
csv_writer.writerow(to_utf8(row))

Or we can even monkey-patch csv_writer to add a write_utf8_row function - the exercise is left to the reader.

Nope. Once the event has been canceled, it is canceled.

You can re-fire the event later on though, using a flag to determine whether your custom code has already run or not - such as this (please ignore the blatant namespace pollution):

var lots_of_stuff_already_done = false;

$('.button').on('click', function(e) {
    if (lots_of_stuff_already_done) {
        lots_of_stuff_already_done = false; // reset flag
        return; // let the event bubble away
    }

    e.preventDefault();

    // do lots of stuff

    lots_of_stuff_already_done = true; // set flag
    $(this).trigger('click');
});

A more generalized variant (with the added benefit of avoiding the global namespace pollution) could be:

function onWithPrecondition(callback) {
    var isDone = false;

    return function(e) {
        if (isDone === true)
        {
            isDone = false;
            return;
        }

        e.preventDefault();

        callback.apply(this, arguments);

        isDone = true;
        $(this).trigger(e.type);
    }
}

Usage:

var someThingsThatNeedToBeDoneFirst = function() { /* ... */ } // do whatever you need
$('.button').on('click', onWithPrecondition(someThingsThatNeedToBeDoneFirst));

Bonus super-minimalistic jQuery plugin with Promise support:

(function( $ ) {
    $.fn.onButFirst = function(eventName,         /* the name of the event to bind to, e.g. 'click' */
                               workToBeDoneFirst, /* callback that must complete before the event is re-fired */
                               workDoneCallback   /* optional callback to execute before the event is left to bubble away */) {
        var isDone = false;

        this.on(eventName, function(e) {
            if (isDone === true) {
                isDone = false;
                workDoneCallback && workDoneCallback.apply(this, arguments);
                return;
            }

            e.preventDefault();

            // capture target to re-fire event at
            var $target = $(this);

            // set up callback for when workToBeDoneFirst has completed
            var successfullyCompleted = function() {
                isDone = true;
                $target.trigger(e.type);
            };

            // execute workToBeDoneFirst callback
            var workResult = workToBeDoneFirst.apply(this, arguments);

            // check if workToBeDoneFirst returned a promise
            if (workResult && $.isFunction(workResult.then))
            {
                workResult.then(successfullyCompleted);
            }
            else
            {
                successfullyCompleted();
            }
        });

        return this;
    };
}(jQuery));

Usage:

$('.button').onButFirst('click',
    function(){
        console.log('doing lots of work!');
    },
    function(){
        console.log('done lots of work!');
    });

The accepted answer doesn't seem to work if you unplug the network cable. Or the server crashes. Or your router crashes. Or if you forget to pay your internet bill. Set the TCP keep-alive options for better reliability.

public static class SocketExtensions
{
    public static void SetSocketKeepAliveValues(this Socket instance, int KeepAliveTime, int KeepAliveInterval)
    {
        //KeepAliveTime: default value is 2hr
        //KeepAliveInterval: default value is 1s and Detect 5 times

        //the native structure
        //struct tcp_keepalive {
        //ULONG onoff;
        //ULONG keepalivetime;
        //ULONG keepaliveinterval;
        //};

        int size = Marshal.SizeOf(new uint());
        byte[] inOptionValues = new byte[size * 3]; // 4 * 3 = 12
        bool OnOff = true;

        BitConverter.GetBytes((uint)(OnOff ? 1 : 0)).CopyTo(inOptionValues, 0);
        BitConverter.GetBytes((uint)KeepAliveTime).CopyTo(inOptionValues, size);
        BitConverter.GetBytes((uint)KeepAliveInterval).CopyTo(inOptionValues, size * 2);

        instance.IOControl(IOControlCode.KeepAliveValues, inOptionValues, null);
    }
}



// ...
Socket sock;
sock.SetSocketKeepAliveValues(2000, 1000);

The time value sets the timeout since data was last sent. Then it attempts to send and receive a keep-alive packet. If it fails it retries 10 times (number hardcoded since Vista AFAIK) in the interval specified before deciding the connection is dead.

So the above values would result in 2+10*1 = 12 second detection. After that any read / wrtie / poll operations should fail on the socket.

Use the -wait parameter with Get-Content, which displays lines as they are added to the file. This feature was present in PowerShell v1, but for some reason not documented well in v2.

Here is an example

Get-Content -Path "C:\scripts\test.txt" -Wait

Once you run this, update and save the file and you will see the changes on the console.

A better idea,

if you want to put the error message just beneath the text field, you can do like this

.row.spacer20top
  .col-sm-6.form-group
    = f.label :first_name, "*Your First Name:"
    = f.text_field :first_name, :required => true, class: "form-control"
    = f.error_message_for(:first_name)

What is error_message_for?
--> Well, this is a beautiful hack to do some cool stuff

      target_elem_id          = "#{model_name}_#{field_name}"

      "</div>"\
      "<!-- Later JavaScript to add class to the parent element -->"\
      "<script>"\
          "document.onreadystatechange = function(){"\
            "$('##{id_of_element}').parent()"\

          "}"\
      "</script>".html_safe
    end
  rescue

end

Result

I commonly like to use a slight variant on the standard for loop. I often use this to run a command on a series of remote hosts. I take advantage of bash's brace expansion to create for loops that allow me to create non-numerical for-loops.

Example:

I want to run the uptime command on frontend hosts 1-5 and backend hosts 1-3:

% for host in {frontend{1..5},backend{1..3}}.mycompany.com
    do ssh $host "echo -n $host; uptime"
  done

I typically run this as a single-line command with semicolons on the ends of the lines instead of the more readable version above. The key usage consideration are that braces allow you to specify multiple values to be inserted into a string (e.g. pre{foo,bar}post results in prefoopost, prebarpost) and allow counting/sequences by using the double periods (you can use a..z etc.). However, the double period syntax is a new feature of bash 3.0; earlier versions will not support this.

Sample file

Note:

• Tried to find the formula for counting non-blank cells (="" is a blank cell) without a need to use data twice. The solution for goolge-spreadhseet: =ARRAYFORMULA(SUM(IFERROR(IF(data="",0,1),1))). For excel ={SUM(IFERROR(IF(data="",0,1),1))} should work (press Ctrl+Shift+Enter in the formula).

Another way to get around this problem, if you are using some server side scripting language that allows you to manipulate the posted data, is to declare your html form like this :

<form>
<input name="a_name"/>
<input name="a_second_name"/>
<input name="subform[another_name]"/>
<input name="subform[another_second_name]"/>
</form>

If you print the posted data (I will use PHP here), you will get an array like this :

//print_r($_POST) will output :
    array(
    'a_name' => 'a_name_value',
    'a_second_name' => 'a_second_name_value',
    'subform' => array(
      'another_name' => 'a_name_value',
      'another_second_name' => 'another_second_name_value',
      ),
    );

Then you can just do something like :

$my_sub_form_data = $_POST['subform'];
unset($_POST['subform']);

Your $_POST now has only your "main form" data, and your subform data is stored in another variable you can manipulate at will.

Hope this helps!

I would comment if i could , but i have no permissions yet, so i will post a hint as an answer, for unexpected behavior on some android devices:

Position: Fixed only works in Android 2.1 thru 2.3 by using the following meta tag:

<meta name="viewport" content="width=device-width, user-scalable=no">.

see http://caniuse.com/#search=position

Another way to achieve this is using old printf() function of C language

You can use this like

int dd = 1, mm = 9, yy = 1;
printf("%02d - %02d - %04d", mm, dd, yy);

This will print 09 - 01 - 0001 on the console.

You can also use another function sprintf() to write formatted output to a string like below:

int dd = 1, mm = 9, yy = 1;
char s[25];
sprintf(s, "%02d - %02d - %04d", mm, dd, yy);
cout << s;

Don't forget to include stdio.h header file in your program for both of these functions

Thing to be noted:

You can fill blank space either by 0 or by another char (not number).
If you do write something like %24d format specifier than this will not fill 2 in blank spaces. This will set pad to 24 and will fill blank spaces.

Apart from cool solutions above I'd mention also about supervisord and monit tools which allow to start process, monitor its presence and start it if it died. With 'monit' you can also run some active checks like check if process responds for http request

If you are using Swift, this will do the same:

buttonName.setTitleColor(UIColor.blackColor(), forState: .Normal)

Hope that helps!

I had the following error message Port 80 in use by "Unable to open process" with PID 4! Apache WILL NOT start without the configured ports free! You need to uninstall/disable/reconfigure the blocking application or reconfigure Apache and the Control Panel to listen on a different port Starting Check-Timer Control Panel Ready

opened the httpd.conf and changed the listen port from 80 to 1234 in both places

Listen 12.34.56.78:1234

Listen 1234

Then go to Config for the xampp control panel and go to service and port setting and changed the port from 80 to 1234

That worked.

As explained, it is not possible to do what I want with JPA, so I employed the hibernate.cascade annotation, with this, the relevant code in the Parent class now looks like this:

@OneToMany(cascade = {CascadeType.PERSIST, CascadeType.MERGE, CascadeType.REFRESH}, mappedBy = "parent")
@Cascade({org.hibernate.annotations.CascadeType.SAVE_UPDATE,
            org.hibernate.annotations.CascadeType.DELETE,
            org.hibernate.annotations.CascadeType.MERGE,
            org.hibernate.annotations.CascadeType.PERSIST,
            org.hibernate.annotations.CascadeType.DELETE_ORPHAN})
private Set<Child> childs = new HashSet<Child>();

I could not simple use 'ALL' as this would have deleted the parent as well.

I was also seeing the same error on browser console for a project based out of require.js. As stated under MISMATCHED ANONYMOUS DEFINE() MODULES at https://requirejs.org/docs/errors.html, this error has multiple causes, the interesting one in my case being: If the problem is the use of loader plugins or anonymous modules but the RequireJS optimizer is not used for file bundling, use the RequireJS optimizer. As it turns out, Google Closure compiler was getting used to merge/minify the Javascript code during build. Solution was to remove the Google closure compiler, and instead use require.js's optimizer (r.js) to merge the js files.

In angular 1.2.10 the line scope.$watch(attrs.dynamic, function(html) { was returning an invalid character error because it was trying to watch the value of attrs.dynamic which was html text.

I fixed that by fetching the attribute from the scope property

 scope: { dynamic: '=dynamic'}, 

My example

angular.module('app')
  .directive('dynamic', function ($compile) {
    return {
      restrict: 'A',
      replace: true,
      scope: { dynamic: '=dynamic'},
      link: function postLink(scope, element, attrs) {
        scope.$watch( 'dynamic' , function(html){
          element.html(html);
          $compile(element.contents())(scope);
        });
      }
    };
  });

If you are using tortoise git.

please follow the below steps.

1. Checkout BranchB
2. Open project folder, go to TortoiseGit --> Pull
3. In pull screen, Change the remote branch "BranchA" and click ok.
4. Then right click again, go to TortoiseGit --> Push.

Now your changes moved from BranchA to BranchB

Short Answer

Yes.

Explanation

It is a good practice since an element can be a part of different groups, and you may want specific elements to be a part of more than one group. The element can hold an infinite number of classes in HTML5, while in HTML4 you are limited by a specific length.

The following example will show you the use of multiple classes.

The first class makes the text color red.

The second class makes the background-color blue.

See how the DOM Element with multiple classes will behave, it will wear both CSS statements at the same time.

Result: multiple CSS statements in different classes will stack up.

You can read more about CSS Specificity.

CSS

.class1 {
    color:red;
}

.class2 {
    background-color:blue;
}

HTML

<div class="class1">text 1</div>
<div class="class2">text 2</div>
<div class="class1 class2">text 3</div>

In case anyone finds this useful, I was getting this issue chronically, although not constantly, and it was because I had git directory within Dropbox, removed it from Dropbox and all was fine.

It is pretty old thread but recently i had a similar issue. I was calling a downstream soap service, from a rest service, and I needed to return the xml response coming from the downstream server as is.

So, i ended up adding a SoapMessageContext handler to get the XML response. Then i injected the response xml into servlet context as an attribute.

public boolean handleMessage(SOAPMessageContext context) {

            // Get xml response
            try {

                ServletContext servletContext =
                        ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest().getServletContext();

                SOAPMessage msg = context.getMessage();

                ByteArrayOutputStream out = new ByteArrayOutputStream();
                msg.writeTo(out);
                String strMsg = new String(out.toByteArray());

                servletContext.setAttribute("responseXml", strMsg);

                return true;
            } catch (Exception e) {
                return false;
            }
        }

Then I have retrieved the xml response string in the service layer.

ServletContext servletContext =
                ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest().getServletContext();

        String msg = (String) servletContext.getAttribute("responseXml");

Didn't have chance to test it yet but this approach must be thread safe since it is using the servlet context.

Yes, I think hashing the file would be the best way if you have to compare several files and store hashes for later comparison. As hash can clash, a byte-by-byte comparison may be done depending on the use case.

Generally byte-by-byte comparison would be sufficient and efficient, which filecmp module already does + other things too.

See http://docs.python.org/library/filecmp.html e.g.

>>> import filecmp
>>> filecmp.cmp('file1.txt', 'file1.txt')
True
>>> filecmp.cmp('file1.txt', 'file2.txt')
False

Speed consideration: Usually if only two files have to be compared, hashing them and comparing them would be slower instead of simple byte-by-byte comparison if done efficiently. e.g. code below tries to time hash vs byte-by-byte

Disclaimer: this is not the best way of timing or comparing two algo. and there is need for improvements but it does give rough idea. If you think it should be improved do tell me I will change it.

import random

def getRandText(N):
    return  "".join([random.choice(string.printable) for i in xrange(N)])

N=1000000
randText1 = getRandText(N)
randText2 = getRandText(N)

def cmpHash(text1, text2):
    hash1 = hashlib.md5()
    hash1.update(text1)
    hash1 = hash1.hexdigest()

    hash2 = hashlib.md5()
    hash2.update(text2)
    hash2 = hash2.hexdigest()

    return  hash1 == hash2

def cmpByteByByte(text1, text2):
    return text1 == text2

for cmpFunc in (cmpHash, cmpByteByByte):
    st = time.time()
    for i in range(10):
        cmpFunc(randText1, randText2)
    print cmpFunc.func_name,time.time()-st

and the output is

cmpHash 0.234999895096
cmpByteByByte 0.0

Try this

If @NewStatus  = 'InOffice' 
BEGIN
     Update tblEmployee set InOffice = -1 where EmpID = @EmpID

    Update tblEmployee set InOffice = -1 where EmpID = @EmpID
END
Else If @NewStatus  = 'Home'
BEGIN
    Update tblEmployee set Home = -1 where EmpID = @EmpID

Since the OP's question is about stripping the newline character from the last element, I would reset it with the_list[-1].rstrip():

>>> the_list = ['Name1', '7.3', '6.9', '6.6', '6.6', '6.1', '6.4', '7.3\n']
>>> the_list[-1] = ls[-1].rstrip()
>>> the_list
['Name1', '7.3', '6.9', '6.6', '6.6', '6.1', '6.4', '7.3']

It's O(1).

Be aware, that \W leaves the underscore. A short equivalent for [^a-zA-Z0-9] would be [\W_]

text.replace(/[\W_]+/g," ");

\W is the negation of shorthand \w for [A-Za-z0-9_] word characters (including the underscore)

To execute a method you need to add parentheses, even if the method does not take arguments.

So it should be:

string t = obj.getTitle();

Yes, you can, you did it in the question itself: <html myAttri="myVal"/>.

QString qstr;
std::string str = qstr.toStdString();

However, if you're using Qt:

QTextStream out(stdout);
out << qstr;

Are you using Angular? If you are it is possible that the webdriver doesn't recognize that the async calls have finished.

I recommend looking at Paul Hammants ngWebDriver. The method waitForAngularRequestsToFinish() could come in handy.

You can use below code to print time in HH:mm format, In my case Property type is TimeSpan So the value is coming in HH:mm:tt format but I have to show in above format ie. HH:mm

So you can use this code:

@Html.TextBoxFor(x =>x.mTimeFrom, null, new {@Value =Model.mTimeFrom.ToString().Substring(0,5), @class = "form-control success" })

Just to extend the answer above you can also index your columns rather than specifying the column names which can also be useful depending on what you're doing. Given that your location is the first field it would look like this:

    bar <- foo[foo[ ,1] == "there", ]

This is useful because you can perform operations on your column value, like looping over specific columns (and you can do the same by indexing row numbers too).

This is also useful if you need to perform some operation on more than one column because you can then specify a range of columns:

    foo[foo[ ,c(1:N)], ]

Or specific columns, as you would expect.

    foo[foo[ ,c(1,5,9)], ]

Keep the breaks - you're less likely to run into trouble if/when you edit the code later if the breaks are already in place.

Having said that, it's considered by many (including me) to be bad practice to return from the middle of a function. Ideally a function should have one entry point and one exit point.

I have the following nginx virtual host (static content) for local development work to disable all browser caching:

server {
    listen 8080;
    server_name localhost;

    location / {
        root /your/site/public;
        index index.html;

        # kill cache
        add_header Last-Modified $date_gmt;
        add_header Cache-Control 'no-store, no-cache, must-revalidate, proxy-revalidate, max-age=0';
        if_modified_since off;
        expires off;
        etag off;
    }
}

No cache headers sent:

$ curl -I http://localhost:8080

Another excellent fractal to learn is the Sierpinski Triangle Fractal.

Basically, draw three corners of a triangle (an equilateral is preferred, but any triangle will work), then start a point P at one of those corners. Move P halfway to any of the 3 corners at random, and draw a point there. Again move P halfway towards any random corner, draw, and repeat.

You'd think the random motion would create a random result, but it really doesn't.

Reference: http://en.wikipedia.org/wiki/Sierpinski_triangle

Currently VARCHAR behaves exactly the same as VARCHAR2. However, the type VARCHAR should not be used as it is reserved for future usage.

Taken from: Difference Between CHAR, VARCHAR, VARCHAR2

Use a negative lookahead and a negative lookbehind:

> s = "one two 3.4 5,6 seven.eight nine,ten"
> parts = re.split('\s|(?<!\d)[,.](?!\d)', s)
['one', 'two', '3.4', '5,6', 'seven', 'eight', 'nine', 'ten']

In other words, you always split by \s (whitespace), and only split by commas and periods if they are not followed (?!\d) or preceded (?<!\d) by a digit.

DEMO.

EDIT: As per @verdesmarald comment, you may want to use the following instead:

> s = "one two 3.4 5,6 seven.eight nine,ten,1.2,a,5"
> print re.split('\s|(?<!\d)[,.]|[,.](?!\d)', s)
['one', 'two', '3.4', '5,6', 'seven', 'eight', 'nine', 'ten', '1.2', 'a', '5']

This will split "1.2,a,5" into ["1.2", "a", "5"].

DEMO.

Just to summarize, here's a complete answer, that worked for me.

My problem was that when I used

[NSString stringWithUTF8String:(char *)data.bytes];

The string I got was unpredictable: Around 70% it did contain the expected value, but too often it resulted with Null or even worse: garbaged at the end of the string.

After some digging I switched to

[[NSString alloc] initWithBytes:(char *)data.bytes length:data.length encoding:NSUTF8StringEncoding];

And got the expected result every time.

Root node is the DocumentElement property of XmlDocument

XmlElement root = xmlDoc.DocumentElement

If you only have the node, you can get the root node by

XmlElement root = xmlNode.OwnerDocument.DocumentElement

Talking specifically about textareas in web forms, for all textareas, on all platforms, \r\n will work.

If you use anything else you will cause issues with cut and paste on Windows platforms.

The line breaks will be canonicalised by windows browsers when the form is submitted, but if you send the form down to the browser with \n linebreaks, you will find that the text will not copy and paste correctly between for example notepad and the textarea.

Interestingly, in spite of the Unix line end convention being \n, the standard in most text-based network protocols including HTTP, SMTP, POP3, IMAP, and so on is still \r\n. Yes, it may not make a lot of sense, but that's history and evolving standards for you!

A simple, but not pure java solution, is to shell out to curl from java, which gives you complete control over how the request is done. If you're just doing this for something simple, this allows you to ignore certificate errors at times, by using this method. This example shows how to make a request against a secure server with a valid or invalid certificate, pass in a cookie, and get the output using curl from java.

import java.io.BufferedReader;
import java.io.File;
import java.io.IOException;
import java.io.InputStreamReader;

public class MyTestClass
{
  public static void main(String[] args) 
  {
    String url = "https://www.google.com";
    String sessionId = "faf419e0-45a5-47b3-96d1-8c62b2a3b558";

    // Curl options are:
    // -k: ignore certificate errors
    // -L: follow redirects
    // -s: non verbose
    // -H: add a http header

    String[] command = { "curl", "-k", "-L", "-s", "-H", "Cookie: MYSESSIONCOOKIENAME=" + sessionId + ";", "-H", "Accept:*/*", url };
    String output = executeShellCmd(command, "/tmp", true, true);
    System.out.println(output);
  }

  public String executeShellCmd(String[] command, String workingFolder, boolean wantsOutput, boolean wantsErrors)
  {
    try
    {
      ProcessBuilder pb = new ProcessBuilder(command);
      File wf = new File(workingFolder);
      pb.directory(wf);

      Process proc = pb.start();
      BufferedReader stdInput = new BufferedReader(new InputStreamReader(proc.getInputStream()));
      BufferedReader stdError = new BufferedReader(new InputStreamReader(proc.getErrorStream()));

      StringBuffer sb = new StringBuffer();
      String newLine = System.getProperty("line.separator");
      String s;

      // read stdout from the command
      if (wantsOutput)
      {
        while ((s = stdInput.readLine()) != null)
        {
          sb.append(s);
          sb.append(newLine);
        }
      }

      // read any errors from the attempted command
      if (wantsErrors)
      {
        while ((s = stdError.readLine()) != null)
        {
          sb.append(s);
          sb.append(newLine);
        }
      }

      String result = sb.toString();

      return result;
    }
    catch (IOException e)
    {
      throw new RuntimeException("Problem occurred:", e);
    }
  }

EXPOSE is used to map local port container port ie : if you specify expose in docker file like

EXPOSE 8090

What will does it will map localhost port 8090 to container port 8090

Setting alpha property of a view affects its subviews. If you want just transparent background set view's backgroundColor proprty to a color that has alpha component smaller than 1.

view.backgroundColor = UIColor.white.withAlphaComponent(0.5)

Run this adding DatabaseName in where condition.

  SELECT TABLE_NAME, ROW_NUMBER() OVER(ORDER BY TABLE_NAME) AS 'RowNumber' 
  FROM INFORMATION_SCHEMA.VIEWS 
  WHERE TABLE_CATALOG = 'DatabaseName'

or remove where condition adding use.

  use DataBaseName

  SELECT TABLE_NAME, ROW_NUMBER() OVER(ORDER BY TABLE_NAME) AS 'RowNumber' 
  FROM INFORMATION_SCHEMA.VIEWS 

If you want to lookup objects based on their String name, this is a textbook case for a Map, say a HashMap. You could use a LinkedHashMap and convert it to a List or Array later (Chris has covered this nicely in the comments below).

LinkedHashMap because it lets you access the elements in the order you insert them if you want to do so. Otherwise HashMap or TreeMap will do.

You could get this to work with List as the others are suggesting, but that feels Hacky to me.. and this will be cleaner both in short and long run.

If you MUST use a list for the object, you could still store a Map of the object name to the index in the array. This is a bit uglier, but you get almost the same performance as a plain Map.

you can try this indside findall for loop:

item_price = item.find('span', attrs={'class':'s-item__price'}).text

it extracts only text and assigs it to "item_pice"

To answer the why question, integral types are special in that they are not a reference to an allocated object but rather values that are duplicated and copied. It's just an implementation decision made when the language was defined, which was to handle values outside the object system and in as efficient and "inline" a fashion as possible.

This doesn't exactly explain why they are allowed as initializors in a type, but think of it as essentially a #define and then it will make sense as part of the type and not part of the object.

It's a default font on Macs, but rare on PCs. Since it's not technically web-safe, some people may have it and some people may not. If you want to use a font like that, without using @font-face, you may want to write it out several different ways because it might not work the same for everyone.

I like using a font stack that touches on all bases like this:

font-family: "HelveticaNeue-Light", "Helvetica Neue Light", "Helvetica Neue", 
  Helvetica, Arial, "Lucida Grande", sans-serif;

This recommended font-family stack is further described in this CSS-Tricks snippet Better Helvetica which uses a font-weight: 300; as well.

Or this:

Range("A2", Range("D" & Rows.Count).End(xlUp).Address).Sort Key1:=[b3], _
    Order1:=xlAscending, Header:=xlYes

1. Go to your project in the navigator, right click on properties.

2. Go to the Java Build Path tab on the left.

3. Go to the libraries tab on top.

4. Click add external jars.

5. Go to your ADT Bundle folder, go to sdk/extras/android/support/v7/appcompat/libs.

6. Select the file android-support-v7-appcompat.jar

7. Go to order and export and check the box next to your new jar.

8. Click ok.

Json.NET allows us to do this:

dynamic d = JObject.Parse("{number:1000, str:'string', array: [1,2,3,4,5,6]}");

Console.WriteLine(d.number);
Console.WriteLine(d.str);
Console.WriteLine(d.array.Count);

Output:

 1000
 string

String file = "";

try {

    InputStream is = new FileInputStream(filename);
    String UTF8 = "utf8";
    int BUFFER_SIZE = 8192;

    BufferedReader br = new BufferedReader(new InputStreamReader(is,
            UTF8), BUFFER_SIZE);
    String str;
    while ((str = br.readLine()) != null) {
        file += str;
    }
} catch (Exception e) {

}

Try this,.. :-)

Sure there is! For instance:

<xsl:if test="not(contains($hhref, '1234'))">
  <li>
    <a href="{$hhref}" title="{$pdate}">
      <xsl:value-of select="title"/>
    </a>
  </li>
</xsl:if>

The syntax is: contains(stringToSearchWithin, stringToSearchFor)

Here are quite a few ways to add dictionaries.

You can use Python3's dictionary unpacking feature.

ndic = {**dic0, **dic1}

Or create a new dict by adding both items.

ndic = dict(dic0.items() + dic1.items())

If your ok to modify dic0

dic0.update(dic1)

If your NOT ok to modify dic0

ndic = dic0.copy()
ndic.update(dic1)

If all the keys in one dict are ensured to be strings (dic1 in this case, of course args can be swapped)

ndic = dict(dic0, **dic1)

In some cases it may be handy to use dict comprehensions (Python 2.7 or newer),
Especially if you want to filter out or transform some keys/values at the same time.

ndic = {k: v for d in (dic0, dic1) for k, v in d.items()}

I happened to encounter this similar SSL problem a few days ago. The problem is your npm does not set root certificate for the certificate used by https://registry.npmjs.org.

Solutions:

1. Use wget https://registry.npmjs.org/coffee-script --ca-certificate=./DigiCertHighAssuranceEVRootCA.crt to fix wget problem
2. Use npm config set cafile /path/to/DigiCertHighAssuranceEVRootCA.crt to set root certificate for your npm program.

you can download root certificate from : https://www.digicert.com/CACerts/DigiCertHighAssuranceEVRootCA.crt

Notice: Different program may use different way of managing root certificate, so do not mix browser's with others.

Analysis:

let's fix your wget https://registry.npmjs.org/coffee-script problem first. your snippet says:

        ERROR: cannot verify registry.npmjs.org's certificate,
        issued by /C=US/ST=CA/L=Oakland/O=npm/OU=npm 
       Certificate Authority/CN=npmCA/[email protected]:
       Unable to locally verify the issuer's authority.

This means that your wget program cannot verify https://registry.npmjs.org's certificate. There are two reasons that may cause this problem:

1. Your wget program does not have this domain's root certificate. The root certificate usually ship with system.
2. The domain does not pack root certificate into his certificate.

So the solution is explicitly set root certificate for https://registry.npmjs.org. We can use openssl to make sure that the reason bellow is the problem.

Try openssl s_client -host registry.npmjs.org -port 443 on the command line and we will get this message (first several lines):

    CONNECTED(00000003)
    depth=1 /C=US/O=DigiCert Inc/OU=www.digicert.com/CN=DigiCert High Assurance CA-3
    verify error:num=20:unable to get local issuer certificate
    verify return:0

       i:/C=US/O=DigiCert Inc/OU=www.digicert.com/CN=DigiCert High Assurance EV Root CA
    ---

This line verify error:num=20:unable to get local issuer certificate makes sure that https://registry.npmjs.org does not pack root certificate. So we Google DigiCert High Assurance EV Root CA root Certificate.

It is easier to achieve it in SQL

var columnsList = dbContext.Database.SqlQuery<string>("SELECT COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_SCHEMA = 'SCHEMA_OF_YOUE_TABLE' AND TABLE_NAME = 'YOUR_TABLE_NAME'").ToList();

import argparse

parser = argparse.ArgumentParser(description='Process some integers.')

You can take advantage of Groovy features like with(), improvements to URLConnection, and simplified getters/setters:

GET:

String getResult = new URL('http://mytestsite/bloop').text

POST:

String postResult
((HttpURLConnection)new URL('http://mytestsite/bloop').openConnection()).with({
    requestMethod = 'POST'
    doOutput = true
    setRequestProperty('Content-Type', '...') // Set your content type.
    outputStream.withPrintWriter({printWriter ->
        printWriter.write('...') // Your post data. Could also use withWriter() if you don't want to write a String.
    })
    // Can check 'responseCode' here if you like.
    postResult = inputStream.text // Using 'inputStream.text' because 'content' will throw an exception when empty.
})

Note, the POST will start when you try to read a value from the HttpURLConnection, such as responseCode, inputStream.text, or getHeaderField('...').
