Piece of cake.

Use 960Grids Go to the automatic layout builder and make a two column, fluid design. Build a left column to the width of grids that works....this is the only challenge using grids and it's very easy once you read a tutorial. In a nutshell, each column in a grid is a certain width, and you set the amount of columns you want to use. To get a column that's exactly a certain width, you have to adjust your math so that your column width is exact. Not too tough.

No chance of wrapping because others have already fought that battle for you. Compatibility back as far as you likely will ever need to go. Quick and easy....Now, download, customize and deploy.

Voila. Grids FTW.

I found that when inserting, the null column values had to be specifically declared as NULL, otherwise I would get a constraint violation error (as opposed to an empty string).

The simplest way to connect is through an OdbcConnection using code like this

using System.Data.Odbc;

using(OdbcConnection myConnection = new OdbcConnection())
{
    myConnection.ConnectionString = myConnectionString;
    myConnection.Open();

    //execute queries, etc

}

where myConnectionString is something like this

myConnectionString = @"Driver={Microsoft Access Driver (*.mdb)};" + 
"Dbq=C:\mydatabase.mdb;Uid=Admin;Pwd=;

See ConnectionStrings

In alternative you could create a DSN and then use that DSN in your connection string

• Open the Control Panel - Administrative Tools - ODBC Data Source Manager
• Go to the System DSN Page and ADD a new DSN
• Choose the Microsoft Access Driver (*.mdb) and press END
• Set the Name of the DSN (choose MyDSN for this example)
• Select the Database to be used
• Try the Compact or Recover commands to see if the connection works

now your connectionString could be written in this way

myConnectionString = "DSN=myDSN;"

I would suggest this simplest solution to use Object.entries()

var obj = {"1":5,"2":7,"3":0,"4":0,"5":0,"6":0,"7":0,"8":0,"9":0,"10":0,"11":0,"12":0}_x000D_
var result =Object.entries(obj)_x000D_
_x000D_
console.log(result);

An alternative to what was proposed before is:

jQuery('form').submit(function(){
     $(this).find(':submit').attr( 'disabled','disabled' );
     //the rest of your code
});

Yes, you can write virtual "functions" in Java.

May be you have added the useEffect that depends on the condition before the one with no condition

EX:

useEffect(() => {
  _anyFunction();
}, []);
    
useEffect(()=> {
  anyCode....
}, [response]);

Using bash globbing (if find is not a must)

ls Robert.{pdf,jpg} 

Setting time interval to check for fix is not a good choice.. i noticed that onLocationChanged is not called if you are not moving.. what is understandable since location is not changing :)

Better way would be for example:

• check interval to last location received (in gpsStatusChanged)
• if that interval is more than 15s set variable: long_interval = true
• remove the location listener and add it again, usually then you get updated position if location really is available, if not - you probably lost location
• in onLocationChanged you just set long_interval to false..

Simple way is to convert into column

SELECT COLUMN_VALUE FROM TABLE (SPLIT ('19869,19572,19223,18898,10155,'))

CREATE TYPE split_tbl as TABLE OF VARCHAR2(32767);

CREATE OR REPLACE FUNCTION split (p_list VARCHAR2, p_del VARCHAR2 := ',')
   RETURN split_tbl
   PIPELINED IS
   l_idx PLS_INTEGER;
   l_list VARCHAR2 (32767) := p_list;
   l_value VARCHAR2 (32767);
BEGIN
   LOOP
      l_idx := INSTR (l_list, p_del);

      IF l_idx > 0 THEN
         PIPE ROW (SUBSTR (l_list, 1, l_idx - 1));
         l_list := SUBSTR (l_list, l_idx + LENGTH (p_del));
      ELSE
         PIPE ROW (l_list);
         EXIT;
      END IF;
   END LOOP;

   RETURN;
END split;

I was able to solve a similar problem like this:

1. Close the Eclipse IDE
2. Remove the .metadata folder from your eclipse workspace
3. Relaunch eclipse

The only disadvantage is that you have to re-import all your projects.

Try out these.

document.getElementById("current").value = 12

// or

var current = document.getElementById("current");
current.value = 12

You failed to load the slick.js file. Add this script file https://kenwheeler.github.io/slick/slick/slick.js.

I updated your JSFiddle by adding an external file on left sidebar External Resources. Then it doesn't report the error: $(...).slick is not a function.

You could use the built-in serialization tools in the framework and serialize to a MemoryStream. This may be the most straightforward option, but might produce a larger byte[] than may be strictly necessary for your scenario.

If that is the case, you could utilize reflection to iterate over the fields and/or properties in the object to be serialized and manually write them to the MemoryStream, calling the serialization recursively if needed to serialize non-trivial types. This method is more complex and will take more time to implement, but allows you much more control over the serialized stream.

It is called the ternary operator. It is shorthand for an if-else block. See here for an example http://www.php.net/manual/en/language.operators.comparison.php#language.operators.comparison.ternary

If it helps, I am using the following to get a gravatar image:

<img
        :src="`https://www.gravatar.com/avatar/${this.gravatarHash(email)}?s=${size}&d=${this.defaultAvatar(email)}`"
        class="rounded-circle"
        :width="size"
    />

You should use the string replace function, with a single regex. Assuming by special characters, you mean anything that's not letter, here is a solution:

const str = "abc's test#s";_x000D_
console.log(str.replace(/[^a-zA-Z ]/g, ""));

find / -exec grep -lR "{test-string}" {} \;

Chrome 76+

Last year I used Linblow's answer (2018-Oct-19) to successfully discover my local IP via javascript. However, recent Chrome updates (76?) have wonked this method so that it now returns an obfuscated IP, such as: 1f4712db-ea17-4bcf-a596-105139dfd8bf.local

If you have full control over your browser, you can undo this behavior by turning it off in Chrome Flags, by typing this into your address bar:

chrome://flags

and DISABLING the flag Anonymize local IPs exposed by WebRTC

In my case, I require the IP for a TamperMonkey script to determine my present location and do different things based on my location. I also have full control over my own browser settings (no Corporate Policies, etc). So for me, changing the chrome://flags setting does the trick.

a variable declared with or without the var keyword got attached to the global object. This is the basis for creating global variables in Node by declaring variables without the var keyword. While variables declared with the var keyword remain local to a module.

Late resurrection.

Your query seems very similar to the one at page 259 of the book Pro JPA 2: Mastering the Java Persistence API, which in JPQL reads:

SELECT e 
FROM Employee e 
WHERE e IN (SELECT emp
              FROM Project p JOIN p.employees emp 
             WHERE p.name = :project)

Using EclipseLink + H2 database, I couldn't get neither the book's JPQL nor the respective criteria working. For this particular problem I have found that if you reference the id directly instead of letting the persistence provider figure it out everything works as expected:

SELECT e 
FROM Employee e 
WHERE e.id IN (SELECT emp.id
                 FROM Project p JOIN p.employees emp 
                WHERE p.name = :project)

Finally, in order to address your question, here is an equivalent strongly typed criteria query that works:

CriteriaBuilder cb = em.getCriteriaBuilder();
CriteriaQuery<Employee> c = cb.createQuery(Employee.class);
Root<Employee> emp = c.from(Employee.class);

Subquery<Integer> sq = c.subquery(Integer.class);
Root<Project> project = sq.from(Project.class);
Join<Project, Employee> sqEmp = project.join(Project_.employees);

sq.select(sqEmp.get(Employee_.id)).where(
        cb.equal(project.get(Project_.name), 
        cb.parameter(String.class, "project")));

c.select(emp).where(
        cb.in(emp.get(Employee_.id)).value(sq));

TypedQuery<Employee> q = em.createQuery(c);
q.setParameter("project", projectName); // projectName is a String
List<Employee> employees = q.getResultList();

If for example you want to get the lines 10 to 20 of a file you can use each of these two methods:

head -n 20 york.txt | tail -11

or

sed -n '10,20p' york.txt 

p in above command stands for printing.

Here's what you'll see:

With a help of a small convenience class, you can measure time spent in indented lines like this:

with CodeTimer():
   line_to_measure()
   another_line()
   # etc...

Which will show the following after the indented line(s) finishes executing:

Code block took: x.xxx ms

UPDATE: You can now get the class with pip install linetimer and then from linetimer import CodeTimer. See this GitHub project.

The code for above class:

import timeit

class CodeTimer:
    def __init__(self, name=None):
        self.name = " '"  + name + "'" if name else ''

    def __enter__(self):
        self.start = timeit.default_timer()

    def __exit__(self, exc_type, exc_value, traceback):
        self.took = (timeit.default_timer() - self.start) * 1000.0
        print('Code block' + self.name + ' took: ' + str(self.took) + ' ms')

You could then name the code blocks you want to measure:

with CodeTimer('loop 1'):
   for i in range(100000):
      pass

with CodeTimer('loop 2'):
   for i in range(100000):
      pass

Code block 'loop 1' took: 4.991 ms
Code block 'loop 2' took: 3.666 ms

And nest them:

with CodeTimer('Outer'):
   for i in range(100000):
      pass

   with CodeTimer('Inner'):
      for i in range(100000):
         pass

   for i in range(100000):
      pass

Code block 'Inner' took: 2.382 ms
Code block 'Outer' took: 10.466 ms

Regarding timeit.default_timer(), it uses the best timer based on OS and Python version, see this answer.

$rootScope is a big global variable, which is fine for one-off things, or small apps. Use a service if you want to encapsulate your model and/or behavior (and possibly reuse it elsewhere). In addition to the google group post the OP mentioned, see also https://groups.google.com/d/topic/angular/eegk_lB6kVs/discussion.

I had a instance of an emulator running and a device connected.

When I ran command `adb -d uninstall PACKAGE_NAME', I got an error 'DELETE_FAILED_INTERNAL_ERROR' but when I killed the Emulator instance, I got a 'success' in un-installation process.

In your case scenario, Why not use GROUP BY and HAVING clause instead of JOINING table to itself. You may also use other useful function. see this link

Another version...

Use strtol, wrapping it inside a simple function to hide its complexity :

inline bool isInteger(const std::string & s)
{
   if(s.empty() || ((!isdigit(s[0])) && (s[0] != '-') && (s[0] != '+'))) return false;

   char * p;
   strtol(s.c_str(), &p, 10);

   return (*p == 0);
}

Why strtol ?

As far as I love C++, sometimes the C API is the best answer as far as I am concerned:

• using exceptions is overkill for a test that is authorized to fail
• the temporary stream object creation by the lexical cast is overkill and over-inefficient when the C standard library has a little known dedicated function that does the job.

How does it work ?

strtol seems quite raw at first glance, so an explanation will make the code simpler to read :

strtol will parse the string, stopping at the first character that cannot be considered part of an integer. If you provide p (as I did above), it sets p right at this first non-integer character.

My reasoning is that if p is not set to the end of the string (the 0 character), then there is a non-integer character in the string s, meaning s is not a correct integer.

The first tests are there to eliminate corner cases (leading spaces, empty string, etc.).

This function should be, of course, customized to your needs (are leading spaces an error? etc.).

Sources :

See the description of strtol at: http://en.cppreference.com/w/cpp/string/byte/strtol.

See, too, the description of strtol's sister functions (strtod, strtoul, etc.).

composer create-project laravel/laravel=4.1.27 your-project-name --prefer-dist

And then you probably need to install all of vendor packages, so

composer install

Second case is also inefficient in terms of String pool, you have to explicitly call intern() on return reference to make it intern.

Use the XML Tools plugin for Notepad++ and then you can Auto-Indent the code with Ctrl+Alt+Shift+B .For the more point-and-click inclined, you could also go to Plugins --> XML Tools --> Pretty Print.

It doesn't matter is your app Boot or just raw Spring. There is just enough to inject org.springframework.core.env.Environment to your bean.

@Autowired
private Environment environment;
....

this.environment.getActiveProfiles();

I prefer inline-block, although float is also useful. Table-cell isn't rendered correctly by old IEs (neither does inline-block, but there's the zoom: 1; *display: inline hack that I use frequently). If you have children that have a smaller height than their parent, floats will bring them to the top, whereas inline-block will screw up sometimes.

Most of the time, the browser will interpret everything correctly, unless, of course, it's IE. You always have to check to make sure that IE doesn't suck-- for example, the table-cell concept.

In all reality, yes, it boils down to personal preference.

One technique you could use to get rid of white space would be to set a font-size of 0 to the parent, then give the font-size back to the children, although that's a hassle, and gross.

1. option 1

   echo $(cat testfile)
   

2. Option 2

   tr ' ' '\n' < testfile
   

I don't use commands. You should be able to do this using the GUI:

• Right-click an empty space in your My Documents folder, select TortoiseSVN > Repo-browser.
• Enter http://subversion... (your URL path to your Subversion server/directory you will save to) as your path and select OK
• Right-click the root directory in Repo and select Add folder. Give it the name of your project and create it.
• Right-click the project folder in the Repo-browser and select Checkout. The Checkout directory will be your Visual Studio\Projects\{your project} folder. Select OK.
• You will receive a warning that the folder is not empty. Say Yes to checkout/export to that folder - it will not overwrite your project files.
• Open your project folder. You will see question marks on folders that are associated with your VS project that have not yet been added to Subversion. Select those folders using Ctrl + Click, then right-click one of the selected items and select TortoiseSVN > Add
• Select OK on the prompt
• Your files should add. Select OK on the Add Finished! dialog
• Right-click in an empty area of the folder and select Refresh. You’ll see “+” icons on the folders/files, now
• Right-click an empty area in the folder once again and select SVN Commit
• Add a message regarding what you are committing and click OK

FYI - none of the above worked for me in 2012 SP1...simple solution was to embed credentials in the shared data source and then tell Safari to trust the SSRS server site. Then it worked great! Took days chasing down supposed solutions like above only to find out integrated security won't work reliably on Safari - you have to mess with the keychain on the mac and then still wouldn't work reliably.

Simple to understand. In Below code, maxKey is the key which is holding the max value.

int maxKey = 0;
int maxValue = 0;
for(int i : birds.keySet())
{
    if(birds.get(i) > maxValue)
    {
        maxKey = i;
        maxValue = birds.get(i);
    }
}

Why not just:

IF object_id('YourFunctionName', 'FN') IS NOT NULL
BEGIN
    DROP FUNCTION [dbo].[YourFunctionName]
END
GO

The second argument of object_id is optional, but can help to identify the correct object. There are numerous possible values for this type argument, particularly:

• FN : Scalar function
• IF : Inline table-valued function
• TF : Table-valued-function
• FS : Assembly (CLR) scalar-function
• FT : Assembly (CLR) table-valued function

this is the solution that works for me...wrote it in another question as well: How to change shape color dynamically?

//get the image button by id
ImageButton myImg = (ImageButton) findViewById(R.id.some_id);

//get drawable from image button
GradientDrawable drawable = (GradientDrawable) myImg.getDrawable();

//set color as integer
//can use Color.parseColor(color) if color is a string
drawable.setColor(color)

The fact that angular is injecting an empty option element to the select is that the model object binded to it by default comes with an empty value in when initialized.

If you want to select a default option then you can probably can set it on the scope in the controller

$scope.filterCondition.operator = "your value here";

If you want to an empty option placeholder, this works for me

<select ng-model="filterCondition.operator" ng-options="operator.id as operator.name for operator in operators">
  <option value="">Choose Operator</option>
</select>

Here's a C# method to do this. Remember to add your own error handling - this mostly assumes that things work for the sake of brevity. It's 4.0+ framework only, but that's mostly because of the optional worksheetNumber parameter. You can overload the method if you need to support earlier versions.

static void ConvertExcelToCsv(string excelFilePath, string csvOutputFile, int worksheetNumber = 1) {
   if (!File.Exists(excelFilePath)) throw new FileNotFoundException(excelFilePath);
   if (File.Exists(csvOutputFile)) throw new ArgumentException("File exists: " + csvOutputFile);

   // connection string
   var cnnStr = String.Format("Provider=Microsoft.Jet.OLEDB.4.0;Data Source={0};Extended Properties=\"Excel 8.0;IMEX=1;HDR=NO\"", excelFilePath);
   var cnn = new OleDbConnection(cnnStr);

   // get schema, then data
   var dt = new DataTable();
   try {
      cnn.Open();
      var schemaTable = cnn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);
      if (schemaTable.Rows.Count < worksheetNumber) throw new ArgumentException("The worksheet number provided cannot be found in the spreadsheet");
      string worksheet = schemaTable.Rows[worksheetNumber - 1]["table_name"].ToString().Replace("'", "");
      string sql = String.Format("select * from [{0}]", worksheet);
      var da = new OleDbDataAdapter(sql, cnn);
      da.Fill(dt);
   }
   catch (Exception e) {
      // ???
      throw e;
   }
   finally {
      // free resources
      cnn.Close();
   }

   // write out CSV data
   using (var wtr = new StreamWriter(csvOutputFile)) {
      foreach (DataRow row in dt.Rows) {
         bool firstLine = true;
         foreach (DataColumn col in dt.Columns) {
            if (!firstLine) { wtr.Write(","); } else { firstLine = false; }
            var data = row[col.ColumnName].ToString().Replace("\"", "\"\"");
            wtr.Write(String.Format("\"{0}\"", data));
         }
         wtr.WriteLine();
      }
   }
}

Etag and Last-modified headers are validators.

They help the browser and/or the cache (reverse proxy) to understand if a file/page, has changed, even if it preserves the same name.

Expires and Cache-control are giving refresh information.

This means that they inform, the browser and the reverse in-between proxies, up to what time or for how long, they may keep the page/file at their cache.

So the question usually is which one validator to use, etag or last-modified, and which refresh infomation header to use, expires or cache-control.

If we are very sure that List<Object> will contain collection of String, then probably try this.

List<Object> lst = new ArrayList<Object>();
lst.add("sample");
lst.add("simple");
String[] arr = lst.toArray(new String[] {});
System.out.println(Arrays.deepToString(arr));

Maybe not very elegant, but it does the job:

exec(open("script.py").read())

I'd say the minimum would be to

• know one of the .Net Languages (C#, VB.NET, etc.)
• know the basic working of the .Net runtime
• know and understand the core parts of the .Net class libraries
• have an understanding about what additional classes and functions are available as part of the .Net class libraries

Here's a quick, admittedly butchered response, but in a sentence:

1NF : Your table is organized as an unordered set of data, and there are no repeating columns.

2NF: You don't repeat data in one column of your table because of another column.

3NF: Every column in your table relates only to your table's key -- you wouldn't have a column in a table that describes another column in your table which isn't the key.

For more detail, see wikipedia...

As someone who has worked with ASP.NET API for about 3 years, I'd recommend returning an HttpResponseMessage instead. Don't use the ActionResult or IEnumerable!

ActionResult is bad because as you've discovered.

Return IEnumerable<> is bad because you may want to extend it later and add some headers, etc.

Using JsonResult is bad because you should allow your service to be extendable and support other response formats as well just in case in the future; if you seriously want to limit it you can do so using Action Attributes, not in the action body.

public HttpResponseMessage GetAllNotificationSettings()
{
    var result = new List<ListItems>();
    // Filling the list with data here...

    // Then I return the list
    return Request.CreateResponse(HttpStatusCode.OK, result);
}

In my tests, I usually use the below helper method to extract my objects from the HttpResponseMessage:

 public class ResponseResultExtractor
    {
        public T Extract<T>(HttpResponseMessage response)
        {
            return response.Content.ReadAsAsync<T>().Result;
        }
    }

var actual = ResponseResultExtractor.Extract<List<ListItems>>(response);

In this way, you've achieved the below:

• Your Action can also return Error Messages and status codes like 404 not found so in the above way you can easily handle it.
• Your Action isn't limited to JSON only but supports JSON depending on the client's request preference and the settings in the Formatter.

Thanks to Gruff Bunny and Louis' comments, I found the source of the issue.

As I use Backbone.js too, I loaded a special build of Lodash compatible with Backbone and Underscore that disables some features. In this example:

var clone = _.clone(data, true);

data[1].values.d = 'x';

• with the Normal build: _.isEqual(data, clone) === false
• with the Underscore build: _.isEqual(data, clone) === true

I just replaced the Underscore build with the Normal build in my Backbone application and the application is still working. So I can now use the Lodash .clone with the expected behaviour.

Edit 2018: the Underscore build doesn't seem to exist anymore. If you are reading this in 2018, you could be interested by this documentation (Backbone and Lodash).

You can use function: wc_get_page_id( 'cart' ) to get the ID of the page. This function will use the page setup as 'cart' page and not the slug. Meaning it will keep working also when you setup a different url for your 'cart' on the settings page. This works for all kind of Woocommerce special page, like 'checkout', 'shop' etc.

example:

if (wc_get_page_id( 'cart' ) == get_the_ID()) {
  // Do something.
}

In short, it lets you assign values to a variable in an outer (but non-global) scope. See PEP 3104 for all the gory details.

A bit late in the game but just in case it helps anyone.

If you are testing using the Sandbox and on the payment page you want to test payments NOT using a PayPal account but using the "Pay with Debit or Credit Card option" (i.e. when a regular Joe/Jane, NOT PayPal users, want to buy your stuff) and want to save yourself some time: just go to a site like http://www.getcreditcardnumbers.com/ and get numbers from there. You can use any Expiry date (in the future) and any numeric CCV (123 works).

The "test credit card numbers" in the PayPal documentation are just another brick in their infuriating wall of convoluted stuff.

I got the url above from PayPal's tech support.

Tested using a simple Hosted button and IPN. Good luck.

#include <stdio.h>
void main(int i){printf("%d\n",i)&&i++<1000&&(*((int*)&i-1)-=5);} 

another one:

#include <stdio.h>
int main(int i){return i<=1000&&printf("%d\n",i)&&main(++i);}

Use a timer with an interval set to 2–3 seconds.

You have three different options to choose from, depending on which type of application you're writing:

1. System.Timers.Timer
2. System.Windows.Forms.Timer
3. System.Threading.Timer

Don't use Thread.Sleep if your application need to process any inputs on that thread at the same time (WinForms, WPF), as Sleep will completely lock up the thread and prevent it from processing other messages. Assuming a single-threaded application (as most are), your entire application will stop responding, rather than just delaying an operation as you probably intended. Note that it may be fine to use Sleep in pure console application as there are no "events" to handle or on separate thread (also Task.Delay is better option).

In addition to timers and Sleep you can use Task.Delay which is asynchronous version of Sleep that does not block thread from processing events (if used properly - don't turn it into infinite sleep with .Wait()).

 public async void ClickHandler(...)
 {
      // whatever you need to do before delay goes here         

      await Task.Delay(2000);

      // whatever you need to do after delay.
 }

The same await Task.Delay(2000) can be used in a Main method of a console application if you use C# 7.1 (Async main on MSDN blogs).

Note: delaying operation with Sleep has benefit of avoiding race conditions that comes from potentially starting multiple operations with timers/Delay. Unfortunately freezing UI-based application is not acceptable so you need to think about what will happen if you start multiple delays (i.e. if it is triggered by a button click) - consider disabling such button, or canceling the timer/task or making sure delayed operation can be done multiple times safely.

I believe question was not whether you can call the static member of the class by calling ClassName::staticMember. Question was what's the difference between using self::classmember and $this->classmember.

For e.g., both of the following examples work without any errors, whether you use self:: or $this->

class Person{
    private $name;
    private $address;

    public function __construct($new_name,$new_address){
        $this->name = $new_name;
        $this->address = $new_address;
    }
}

class Person{
    private $name;
    private $address;
    public function __construct($new_name,$new_address){
        self::$name = $new_name;
        self::$address = $new_address;
    }
}

# Open the file
f = open('morseCode.txt', 'r')

# Read the morse code data into "letters" [(lowercased letter, morse code), ...]
letters = []
for Line in f:
    if not Line.strip(): break
    letter, code = Line.strip().split() # Assuming the format is <letter><whitespace><morse code><newline>
    letters.append((letter.lower(), code))
f.close()

# Get the input from the user
# (Don't use input() - it calls eval(raw_input())!)
i = raw_input("Enter a string to be converted to morse code or press <enter> to quit ") 

# Convert the codes to morse code
out = []
for c in i:
    found = False
    for letter, code in letters:
        if letter == c.lower():
            found = True
            out.append(code)
            break

    if not found: 
        raise Exception('invalid character: %s' % c)

# Print the output
print ' '.join(out)

In my opinion, it's a way to implement currying in python.

from functools import partial
def add(a,b):
    return a + b

def add2number(x,y,z):
    return x + y + z

if __name__ == "__main__":
    add2 = partial(add,2)
    print("result of add2 ",add2(1))
    add3 = partial(partial(add2number,1),2)
    print("result of add3",add3(1))

The result is 3 and 4.

My answer is to:

a) use StringBuilder when possible

b) keep (in any form: integer is the best, speciall char like dollar macro etc) position of "placeholder" and then use StringBuilder.insert() (few versions of arguments).

Using external libraries seems overkill and I belive degrade performance significant, when StringBuilder is converted to String internally.

The body hasn't been defined at this point yet. In general, you want to create all elements before you execute javascript that uses these elements. In this case you have some javascript in the head section that uses body. Not cool.

You want to wrap this code in a window.onload handler or place it after the <body> tag (as mentioned by e-bacho 2.0).

<head>
    <title>Javascript Tests</title>

    <script type="text/javascript">
      window.onload = function() {
        var mySpan = document.createElement("span");
        mySpan.innerHTML = "This is my span!";

        mySpan.style.color = "red";
        document.body.appendChild(mySpan);

        alert("Why does the span change after this alert? Not before?");
      }

    </script>
</head>

See demo.

try this one

    <dependency>
        <groupId>com.hynnet</groupId>
        <artifactId>oracle-driver-ojdbc6</artifactId>
        <version>12.1.0.1</version>

using DB facade you can perform SQL queries

 public function index()
{
    return DB::table('table_name')->get();
}

Like taro said, keys returns the array of keys of your Hash:

http://ruby-doc.org/core-1.9.3/Hash.html#method-i-keys

You'll find all the different methods available for each class.

If you don't know what you're dealing with:

 puts my_unknown_variable.class.to_s

This will output the class name.

Since you mentioned that you are using Newtonsoft.dll you can convert a JSON string to an object by using its facilities:

MyClass myClass = JsonConvert.DeserializeObject<MyClass>(your_json_string);

[Serializable]
public class MyClass
{
    public string myVar {get; set;}
    etc.
}

As Lamak pointed out in the comment, COALESCE(column, CAST(0 AS BIGINT)) resolves the error.

In the second image it looks like you want the image to fill the box, but the example you created DOES keep the aspect ratio (the pets look normal, not slim or fat).

I have no clue if you photoshopped those images as example or the second one is "how it should be" as well (you said IS, while the first example you said "should")

Anyway, I have to assume:

If "the images are not resized keeping the aspect ration" and you show me an image which DOES keep the aspect ratio of the pixels, I have to assume you are trying to accomplish the aspect ratio of the "cropping" area (the inner of the green) WILE keeping the aspect ratio of the pixels. I.e. you want to fill the cell with the image, by enlarging and cropping the image.

If that's your problem, the code you provided does NOT reflect "your problem", but your starting example.

Given the previous two assumptions, what you need can't be accomplished with actual images if the height of the box is dynamic, but with background images. Either by using "background-size: contain" or these techniques (smart paddings in percents that limit the cropping or max sizes anywhere you want): http://fofwebdesign.co.uk/template/_testing/scale-img/scale-img.htm

The only way this is possible with images is if we FORGET about your second iimage, and the cells have a fixed height, and FORTUNATELY, judging by your sample images, the height stays the same!

So if your container's height doesn't change, and you want to keep your images square, you just have to set the max-height of the images to that known value (minus paddings or borders, depending on the box-sizing property of the cells)

Like this:

<div class="content">
  <div class="row">    
      <div class="cell">    
          <img src="http://lorempixel.com/output/people-q-c-320-320-2.jpg"/>
      </div>
      <div class="cell">    
          <img src="http://lorempixel.com/output/people-q-c-320-320-7.jpg"/>
      </div>
    </div>
</div>

And the CSS:

.content {
    background-color: green;
}

.row {
    display: -webkit-box;
    display: -moz-box;
    display: -ms-flexbox;
    display: -webkit-flex;
    display: flex;

    -webkit-box-orient: horizontal; 
    -moz-box-orient: horizontal;
    box-orient: horizontal;
    flex-direction: row;

    -webkit-box-pack: center;
    -moz-box-pack: center;
    box-pack: center;
    justify-content: center;

    -webkit-box-align: center;
    -moz-box-align: center;
    box-align: center;  
    align-items: center;

}

.cell {
    -webkit-box-flex: 1;
    -moz-box-flex: 1;
    box-flex: 1;
    -webkit-flex: 1 1 auto;
    flex: 1 1 auto;
    padding: 10px;
    border: solid 10px red;
    text-align: center;
    height: 300px;
    display: flex;
    align-items: center;
    box-sizing: content-box;
}
img {
    margin: auto;
    width: 100%;
    max-width: 300px;
    max-height:100%
}

Your code is invalid (opening tags are instead of closing ones, so they output NESTED cells, not siblings, he used a SCREENSHOT of your images inside the faulty code, and the flex box is not holding the cells but both examples in a column (you setup "row" but the corrupt code nesting one cell inside the other resulted in a flex inside a flex, finally working as COLUMNS. I have no idea what you wanted to accomplish, and how you came up with that code, but I'm guessing what you want is this.

I added display: flex to the cells too, so the image gets centered (I think display: table could have been used here as well with all this markup)

When condition is really complex I use the following style (PHP real life example):

if( $format_bool &&
    (
        ( isset( $column_info['native_type'] )
            && stripos( $column_info['native_type'], 'bool' ) !== false
        )
        || ( isset( $column_info['driver:decl_type'] )
            && stripos( $column_info['driver:decl_type'], 'bool' ) !== false
        )
        || ( isset( $column_info['pdo_type'] )
            && $column_info['pdo_type'] == PDO::PARAM_BOOL
        )
    )
)

I believe it's more nice and readable than nesting multiple levels of if(). And in some cases like this you simply can't break complex condition into pieces because otherwise you would have to repeat the same statements in if() {...} block many times.

I also believe that adding some "air" into code is always a good idea. It improves readability greatly.

You have to explicitly define the constructor in B and explicitly call the constructor for the parent.

B(int x) : A(x) { }

or

B() : A(5) { }

For multiple checkbox with same name... Code to remove unnecessary false :

List<string> d_taxe1 = new List<string>(Request.Form.GetValues("taxe1"));
d_taxe1 = form_checkbox.RemoveExtraFalseFromCheckbox(d_taxe1);

Function

public class form_checkbox
{

    public static List<string> RemoveExtraFalseFromCheckbox(List<string> val)
    {
        List<string> d_taxe1_list = new List<string>(val);

        int y = 0;

        foreach (string cbox in val)
        {

            if (val[y] == "false")
            {
                if (y > 0)
                {
                    if (val[y - 1] == "true")
                    {
                        d_taxe1_list[y] = "remove";
                    }
                }

            }

            y++;
        }

        val = new List<string>(d_taxe1_list);

        foreach (var del in d_taxe1_list)
            if (del == "remove") val.Remove(del);

        return val;

    }      



}

Use it :

int x = 0;
foreach (var detail in d_prix){
factured.taxe1 = (d_taxe1[x] == "true") ? true : false;
x++;
}

It may be more maintainable to two regexes in your code, one to do the first match, and then if it matches run the second regex to check for outlier cases you wish to block for example ^.*(hede).* then have appropriate logic in your code.

OK, I admit this is not really an answer to the posted question posted and it may also use slightly more processing than a single regex. But for developers who came here looking for a fast emergency fix for an outlier case then this solution should not be overlooked.

What is currentWorksheet? It works if you use the built-in ActiveSheet.

dataStartRow=1
dataStartCol=1
dataEndRow=4
dataEndCol=4
Set currentWorksheet=ActiveSheet
dataTable = currentWorksheet.Range(currentWorksheet.Cells(dataStartRow, dataStartCol), currentWorksheet.Cells(dataEndRow, dataEndCol))

((yes).*(no))|((no).*(yes))

Will match sentence having both yes and no at the same time, regardless the order in which they appear:

Do i like cookies? **Yes**, i do. But milk - **no**, definitely no.

**No**, you may not have my phone. **Yes**, you may go f yourself.

Will both match, ignoring case.

The problem it may cause if you do not synchronize before wait() is as follows:

1. If the 1st thread goes into makeChangeOnX() and checks the while condition, and it is true (x.metCondition() returns false, means x.condition is false) so it will get inside it. Then just before the wait() method, another thread goes to setConditionToTrue() and sets the x.condition to true and notifyAll().
2. Then only after that, the 1st thread will enter his wait() method (not affected by the notifyAll() that happened few moments before). In this case, the 1st thread will stay waiting for another thread to perform setConditionToTrue(), but that might not happen again.

But if you put synchronized before the methods that change the object state, this will not happen.

class A {

    private Object X;

    makeChangeOnX(){
        while (! x.getCondition()){
            wait();
            }
        // Do the change
    }

    setConditionToTrue(){
        x.condition = true; 
        notifyAll();

    }
    setConditionToFalse(){
        x.condition = false;
        notifyAll();
    }
    bool getCondition(){
        return x.condition;
    }
}

Only need to fill datagrid again like this:

this.XXXTableAdapter.Fill(this.DataSet.XXX);

If you use automaticlly connect from dataGridView this code create automaticlly in Form_Load()

Noone cand read the file except for those who have access to the file. You must make the code readable (but not writable) by the web server. If the php code handler is running properly you can't read it by requesting by name from the web server.

If someone compromises your server you are at risk. Ensure that the web server can only write to locations it absolutely needs to. There are a few locations under /var which should be properly configured by your distribution. They should not be accessible over the web. /var/www should not be writable, but may contain subdirectories written to by the web server for dynamic content. Code handlers should be disabled for these.

Ensure you don't do anything in your php code which can lead to code injection. The other risk is directory traversal using paths containing .. or begining with /. Apache should already be patched to prevent this when it is handling paths. However, when it runs code, including php, it does not control the paths. Avoid anything that allows the web client to pass a file path.

try below code it will solve your problem.

Configuration  configuration = new Configuration().configure("/logic/hibernate.cfg.xml");

If using TextBox2.Text as the source for a numeric value, it must first be checked to see if a value exists, and then converted to integer.

If the text box is blank when Convert.ToInt32 is called, you will receive the System.FormatException. Suggest trying:

protected void SetImageWidth()
{
   try{
      Image1.Width = Convert.ToInt32(TextBox1.Text);
   }
   catch(System.FormatException)
   {
      Image1.Width = 100; // or other default value as appropriate in context.
   }
}

$('input').each(function() {
    if ($(this).val() != '') {
        console.log('all inputs filled');
    }
    else{
        console.log('theres an empty input');
        return false
    }
});

you might want to wrap this in a keyup function

Avoid async void. Have your methods return Task instead of void. Then you can await them.

Like this:

private async Task RequestToSendOutputReport(List<byte[]> byteArrays)
{
    foreach (byte[] b in byteArrays)
    {
        while (condition)
        {
            // we'll typically execute this code many times until the condition is no longer met
            Task t = SendOutputReportViaInterruptTransfer();
            await t;
        }

        // read some data from device; we need to wait for this to return
        await RequestToGetInputReport();
    }
}

private async Task RequestToGetInputReport()
{
    // lots of code prior to this
    int bytesRead = await GetInputReportViaInterruptTransfer();
}

My issue was that I was declaring two fonts, and scss seems to expect that you declare the name of the font.

after your @font-face{} you must declare $my-font: "OpenSans3.0 or whatever";

and this for each font-face.

:-)

This worked for me while the other solutions were not!

1. Update your jupyters
2. Start your jupyters via your preferred notebook or lab but add this code at the end of the line in the console: <--no-browser>

This is stopping to need to be connected to your EC2 instance all the time. Therefore even if you loose connection due to internet connection loss, whenever you gain a new wifi access it automatically re-connects to the actively working kernel.

Also, don't forget to start your jupyter in a tmux account or a ngnix or other environments like that.

Hope this helps!

Use the function Contains from the strings package.

import (
    "strings"
)
strings.Contains("something", "some") // true

If you only need the dynamic properties for JSON serialization/deserialization, eg if your API accepts a JSON object with different fields depending on context, then you can use the JsonExtensionData attribute available in Newtonsoft.Json or System.Text.Json.

Example:

public class Pet
{
    public string Name { get; set; }
    public string Type { get; set; }

    [JsonExtensionData]
    public IDictionary<string, object> AdditionalData { get; set; }
}

Then you can deserialize JSON:

public class Program
{
    public static void Main()
    {
        var bingo = JsonConvert.DeserializeObject<Pet>("{\"Name\": \"Bingo\", \"Type\": \"Dog\", \"Legs\": 4 }");
        Console.WriteLine(bingo.AdditionalData["Legs"]);        // 4

        var tweety = JsonConvert.DeserializeObject<Pet>("{\"Name\": \"Tweety Pie\", \"Type\": \"Bird\", \"CanFly\": true }");
        Console.WriteLine(tweety.AdditionalData["CanFly"]);     // True

        tweety.AdditionalData["Color"] = "#ffff00";

        Console.WriteLine(JsonConvert.SerializeObject(tweety)); // {"Name":"Tweety Pie","Type":"Bird","CanFly":true,"Color":"#ffff00"}
    }
}

For those who is not able to access/install at in environment, can use custom script:

#!/bin/bash
if [ $# -lt 2 ]; then
echo ""
echo "Syntax Error!"
echo "Usage: $0 <shell script> <datetime>"
echo "<datetime> format: %Y%m%d%H%M"
echo "Example: $0 /home/user/scripts/server_backup.sh 202008142350"
echo ""
exit 1
fi

while true; do
  t=$(date +%Y%m%d%H%M);      
  if [ $t -eq $2 ]; then
    /bin/bash $1
    echo DONE $(date);
    break;
  fi;
  sleep 1;
done

Let's name the script as run1time.sh Example could be something like:

nohup bash run1time.sh /path/to/your/script.sh 202008150300 &

That line works as-is in Python 3.

>>> sys.version
'3.2 (r32:88445, Oct 20 2012, 14:09:29) \n[GCC 4.5.2]'
>>> "(%d goals, $%d)" % (self.goals, self.penalties)
'(1 goals, $2)'

in your location block you can do:

location / {
  try_files $uri $uri/index.html;
}

which will tell ngingx to look for a file with the exact name given first, and if none such file is found it will try uri/index.html. So if a request for https://www.example.com/ comes it it would look for an exact file match first, and not finding that would then check for index.html

Here is my utility function for UTF8, which can be replaced with ASCII if desired:

    public static byte[] MD5Hash(string message)
    {
        return MD5.Create().ComputeHash(Encoding.UTF8.GetBytes(message));
    }

You could prototype your array to make it more modular, try something like this

    Array.prototype.hasElement = function(element) {
        var i;
        for (i = 0; i < this.length; i++) {
            if (this[i] === element) {
                return i; //Returns element position, so it exists
            }
        }

        return -1; //The element isn't in your array
    };

And you can use it as:

 yourArray.hasElement(yourArrayElement)

It's good practice to always use the [] notation. One reason is that attribute notation (df.column_name) does not work for numbered indices:

In [1]: df = DataFrame([[1, 2, 3], [4, 5, 6]])

In [2]: df[1]
Out[2]:
0    2
1    5
Name: 1

In [3]: df.1
  File "<ipython-input-3-e4803c0d1066>", line 1
    df.1
       ^
SyntaxError: invalid syntax

var t = document.getElementById("table"),
    d = t.getElementsByTagName("tr"),
    r = d.getElementsByTagName("td");

needs to be:

var t = document.getElementById("table"),
    tableRows = t.getElementsByTagName("tr"),
    r = [], i, len, tds, j, jlen;

for ( i =0, len = tableRows.length; i<len; i++) {
    tds = tableRows[i].getElementsByTagName('td');
    for( j = 0, jlen = tds.length; j < jlen; j++) {
        r.push(tds[j]);
    }
}

Because getElementsByTagName returns a NodeList an Array-like structure. So you need to loop through the return nodes and then populate you r like above.

Please don't use any library for this effect instead use the recommended way of doing it according to Google I/O. In your recyclerView's onBindViewHolder method do this:

final boolean isExpanded = position==mExpandedPosition;
holder.details.setVisibility(isExpanded?View.VISIBLE:View.GONE);
holder.itemView.setActivated(isExpanded);
holder.itemView.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        mExpandedPosition = isExpanded ? -1:position;
        TransitionManager.beginDelayedTransition(recyclerView);
        notifyDataSetChanged();
    }
});

• Where details is my view that will be displayed on touch (call details in your case. Default Visibility.GONE).
• mExpandedPosition is an int variable initialized to -1

And for the cool effects that you wanted, use these as your list_item attributes:

android:background="@drawable/comment_background"
android:stateListAnimator="@animator/comment_selection"

where comment_background is:

<selector
xmlns:android="http://schemas.android.com/apk/res/android"
android:constantSize="true"
android:enterFadeDuration="@android:integer/config_shortAnimTime"
android:exitFadeDuration="@android:integer/config_shortAnimTime">

<item android:state_activated="true" android:drawable="@color/selected_comment_background" />
<item android:drawable="@color/comment_background" />
</selector>

and comment_selection is:

<selector xmlns:android="http://schemas.android.com/apk/res/android">

<item android:state_activated="true">
    <objectAnimator
        android:propertyName="translationZ"
        android:valueTo="@dimen/z_card"
        android:duration="2000"
        android:interpolator="@android:interpolator/fast_out_slow_in" />
</item>

<item>
    <objectAnimator
        android:propertyName="translationZ"
        android:valueTo="0dp"
        android:duration="2000"
        android:interpolator="@android:interpolator/fast_out_slow_in" />
</item>

I used Excel Compare. It is payware, but they do have a 15 day trial. It will report amended rows, added rows, and deleted rows. It will match based on the worksheet name (as an option):

http://www.formulasoft.com/excel-compare.html

You also may do git fetch followed by a git branch -r. Without fetch you will not see the most current branches.

Try this:

SELECT s.NAME + '.' + t.NAME AS TableName
FROM sys.tables t
INNER JOIN sys.schemas s
    ON t.schema_id = s.schema_id

it will display the schema+table name for all tables in the current database.

Here is a version that will list every table in every database on the current server. it allows a search parameter to be used on any part or parts of the server+database+schema+table names:

SET NOCOUNT ON
DECLARE @AllTables table (CompleteTableName nvarchar(4000))
DECLARE @Search nvarchar(4000)
       ,@SQL   nvarchar(4000)
SET @Search=null --all rows
SET @SQL='select @@SERVERNAME+''.''+''?''+''.''+s.name+''.''+t.name from [?].sys.tables t inner join sys.schemas s on t.schema_id=s.schema_id WHERE @@SERVERNAME+''.''+''?''+''.''+s.name+''.''+t.name LIKE ''%'+ISNULL(@SEARCH,'')+'%'''

INSERT INTO @AllTables (CompleteTableName)
    EXEC sp_msforeachdb @SQL
SET NOCOUNT OFF
SELECT * FROM @AllTables ORDER BY 1

set @Search to NULL for all tables, set it to things like 'dbo.users' or 'users' or '.master.dbo' or even include wildcards like '.master.%.u', etc.

Check indexes of that collection in MongoDB compass and remove those indexes which are not related to it or for try remove all indexes(Not from code but in db).

I could not understand those 3 rules in the specs too well -- hope to have something that is more plain English -- but here is what I gathered from JavaScript: The Definitive Guide, 6th Edition, David Flanagan, O'Reilly, 2011:

Quote:

JavaScript does not treat every line break as a semicolon: it usually treats line breaks as semicolons only if it can’t parse the code without the semicolons.

Another quote: for the code

var a
a
=
3 console.log(a)

JavaScript does not treat the second line break as a semicolon because it can continue parsing the longer statement a = 3;

and:

two exceptions to the general rule that JavaScript interprets line breaks as semicolons when it cannot parse the second line as a continuation of the statement on the first line. The first exception involves the return, break, and continue statements

... If a line break appears after any of these words ... JavaScript will always interpret that line break as a semicolon.

... The second exception involves the ++ and -- operators ... If you want to use either of these operators as postfix operators, they must appear on the same line as the expression they apply to. Otherwise, the line break will be treated as a semicolon, and the ++ or -- will be parsed as a prefix operator applied to the code that follows. Consider this code, for example:

x 
++ 
y

It is parsed as x; ++y;, not as x++; y

So I think to simplify it, that means:

In general, JavaScript will treat it as continuation of code as long as it makes sense -- except 2 cases: (1) after some keywords like return, break, continue, and (2) if it sees ++ or -- on a new line, then it will add the ; at the end of the previous line.

The part about "treat it as continuation of code as long as it makes sense" makes it feel like regular expression's greedy matching.

With the above said, that means for return with a line break, the JavaScript interpreter will insert a ;

(quoted again: If a line break appears after any of these words [such as return] ... JavaScript will always interpret that line break as a semicolon)

and due to this reason, the classic example of

return
{ 
  foo: 1
}

will not work as expected, because the JavaScript interpreter will treat it as:

return;   // returning nothing
{
  foo: 1
}

There has to be no line-break immediately after the return:

return { 
  foo: 1
}

for it to work properly. And you may insert a ; yourself if you were to follow the rule of using a ; after any statement:

return { 
  foo: 1
};

In asp.net Core / MVC 6 rc2 you can set the HttpContext

var SomeController controller = new SomeController();

controller.ControllerContext = new ControllerContext();
controller.ControllerContext.HttpContext = new DefaultHttpContext();
controller.HttpContext.Session = new DummySession();

rc 1 was

var SomeController controller = new SomeController();

controller.ActionContext = new ActionContext();
controller.ActionContext.HttpContext = new DefaultHttpContext();
controller.HttpContext.Session = new DummySession();

Using .format from Python 2.6 and higher:

>>> print '{}{}{}{}'.format(*[7,7,7,7])
7777
>>> data = [7, 7, 7, 7] * 3
>>> print ('{}'*len(data)).format(*data)
777777777777777777777777

For Python 3:

>>> print(('{}'*len(data)).format(*data))
777777777777777777777777

We can use keyboard and tochablewithoutfeedback from react-native

const DismissKeyboard = ({ children }) => (
  <TouchableWithoutFeedback
    onPress={() => Keyboard.dismiss()}
  >
    {children}
  </TouchableWithoutFeedback>
);

And use it in this way:

const App = () => (
  <DismissKeyboard>
    <View style={styles.container}>
      <TextInput
        style={styles.input}
        placeholder="username"
        keyboardType="numeric"
      />
      <TextInput
        style={styles.input}
        placeholder="password"
      />
    </View>
  </DismissKeyboard>
);

I also explained here with source code.

The following code creates an Array object called myCars:

var myCars=new Array();

There are two ways of adding values to an array (you can add as many values as you need to define as many variables you require).

1:

var myCars=new Array();
myCars[0]="Saab";
myCars[1]="Volvo";
myCars[2]="BMW";

You could also pass an integer argument to control the array's size:

var myCars=new Array(3);
myCars[0]="Saab";
myCars[1]="Volvo";
myCars[2]="BMW";

2:

var myCars=new Array("Saab","Volvo","BMW");

Note: If you specify numbers or true/false values inside the array then the type of variables will be numeric or Boolean instead of string.

Access an Array

You can refer to a particular element in an array by referring to the name of the array and the index number. The index number starts at 0.

The following code line:

document.write(myCars[0]);

will result in the following output:

Saab

Modify Values in an Array

To modify a value in an existing array, just add a new value to the array with a specified index number:

myCars[0]="Opel";

Now, the following code line:

document.write(myCars[0]);

will result in the following output:

Opel

If you don't have to do any group functions (sum, average etc in case you want to add numeric data to the table), use SELECT DISTINCT. I suspect it's faster, but i have nothing to show for it.

In any case, if you're worried about speed, create an index on the column.

In Angular 8 we can do like this:

import { Injectable } from '@angular/core';
import { YourModel} from '../models/<yourModel>.model';
import { UserService } from './user.service';
import { Observable, of } from 'rxjs';
import { map, catchError } from 'rxjs/operators';
import { HttpClient } from '@angular/common/http';

@Injectable({
  providedIn: 'root'
})

export class GlobalDataService {

  private me: <YourModel>;

  private meObservable: Observable<User>;

  constructor(private yourModalService: <yourModalService>, private http: HttpClient) {

  }

  ngOnInit() {

  }


  getYourModel(): Observable<YourModel> {

    if (this.me) {
      return of(this.me);
    } else if (this.meObservable) {
      return this.meObservable;
    }
    else {
      this.meObservable = this.yourModalService.getCall<yourModel>() // Your http call
      .pipe(
        map(data => {
          this.me = data;
          return data;
        })
      );
      return this.meObservable;
    }
  }
}

You can call it like this:

this.globalDataService.getYourModel().subscribe(yourModel => {


});

The above code will cache the result of remote API at first call so that it can be used on further requests to that method.

Just remove COLUMN from ADD COLUMN

ALTER TABLE Employees
  ADD EmployeeID numeric NOT NULL IDENTITY (1, 1)

ALTER TABLE Employees ADD CONSTRAINT
        PK_Employees PRIMARY KEY CLUSTERED 
        (
          EmployeeID
        ) WITH( STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, 
        ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]

Dictionaries are specifically designed to do super fast key lookups. They are implemented as hashtables and the more entries the faster they are relative to other methods. Using the exception engine is only supposed to be done when your method has failed to do what you designed it to do because it is a large set of object that give you a lot of functionality for handling errors. I built an entire library class once with everything surrounded by try catch blocks once and was appalled to see the debug output which contained a seperate line for every single one of over 600 exceptions!

I ran into this same situation (in my case with a date value in a custom PHP field in a Drupal view), and what worked for me was using intval instead of strtotime to turn the value into an integer - because it basically was a timestamp, but in the form of a string rather than an integer. Obviously that won't be the case for everyone, but it might be worth a try.

This is probably a good starting point (version 8.4+ only):

SELECT id_field, array_agg(value_field1), array_agg(value_field2)
FROM data_table
GROUP BY id_field

array_agg returns an array, but you can CAST that to text and edit as needed (see clarifications, below).

Prior to version 8.4, you have to define it yourself prior to use:

CREATE AGGREGATE array_agg (anyelement)
(
    sfunc = array_append,
    stype = anyarray,
    initcond = '{}'
);

(paraphrased from the PostgreSQL documentation)

Clarifications:

• The result of casting an array to text is that the resulting string starts and ends with curly braces. Those braces need to be removed by some method, if they are not desired.
• Casting ANYARRAY to TEXT best simulates CSV output as elements that contain embedded commas are double-quoted in the output in standard CSV style. Neither array_to_string() or string_agg() (the "group_concat" function added in 9.1) quote strings with embedded commas, resulting in an incorrect number of elements in the resulting list.
• The new 9.1 string_agg() function does NOT cast the inner results to TEXT first. So "string_agg(value_field)" would generate an error if value_field is an integer. "string_agg(value_field::text)" would be required. The array_agg() method requires only one cast after the aggregation (rather than a cast per value).

Here you have not specified class name to be imported from Map.js file. If Map is class exportable class name exist in the Map.js file, your code should be as follow.

import React, { Component } from 'react';
import Map from  './Map';
class App extends Component {
   render() {
     return (
         <div className="App">
            <Map/>
         </div>
     );
   }
}
export default App;

For the people who are using the Asset Catalog's Launch Image, as I learned this the hardest way, I had this scenario where I was first given a jpg file then I asked them convert it to PNG.

I trusted them enough that I scoured the internet first as to why the launch image wasn't showing and did every solution to no avail, then I tried putting back the old launch image and was working fine, it was there that I thought what I have is not a proper PNG file.

TL;DR: Make sure that you are actually using a proper PNG file, not a file with a renamed extension.

I would exploit the retransmission behaviour of TCP.

1. Make the TCP component create a large receive window.
2. Receive some amount of packets without sending an ACK for them.
   • Process those in passes creating some (prefix) compressed data structure
   • Send duplicate ack for last packet that is not needed anymore/wait for retransmission timeout
   • Goto 2
3. All packets were accepted

This assumes some kind of benefit of buckets or multiple passes.

Probably by sorting the batches/buckets and merging them. -> radix trees

Use this technique to accept and sort the first 80% then read the last 20%, verify that the last 20% do not contain numbers that would land in the first 20% of the lowest numbers. Then send the 20% lowest numbers, remove from memory, accept the remaining 20% of new numbers and merge.**

For a Simple line Handle Post delay, you can do as following :

new Handler().postDelayed(new Runnable() {
    @Override
    public void run() {
        // Do someting
    }
}, 3000);

I hope this helps

Thanks everyone especially szatmary as this is a complex question and has many layers to it, all which have to be working before you can stream live video. To clarify my original question and HTML5 video use vs flash - my use case has a strong preference for HTML5 because it is generic, easy to implement on the client and the future. Flash is a distant second best so lets stick with HTML5 for this question.

I learnt a lot through this exercise and agree live streaming is much harder than VOD (which works well with HTML5 video). But I did get this to work satisfactorily for my use case and the solution worked out to be very simple, after chasing down more complex options like MSE, flash, elaborate buffering schemes in Node. The problem was that FFMPEG was corrupting the fragmented MP4 and I had to tune the FFMPEG parameters, and the standard node stream pipe redirection over http that I used originally was all that was needed.

In MP4 there is a 'fragmentation' option that breaks the mp4 into much smaller fragments which has its own index and makes the mp4 live streaming option viable. But not possible to seek back into the stream (OK for my use case), and later versions of FFMPEG support fragmentation.

Note timing can be a problem, and with my solution I have a lag of between 2 and 6 seconds caused by a combination of the remuxing (effectively FFMPEG has to receive the live stream, remux it then send it to node for serving over HTTP). Not much can be done about this, however in Chrome the video does try to catch up as much as it can which makes the video a bit jumpy but more current than IE11 (my preferred client).

Rather than explaining how the code works in this post, check out the GIST with comments (the client code isn't included, it is a standard HTML5 video tag with the node http server address). GIST is here: https://gist.github.com/deandob/9240090

I have not been able to find similar examples of this use case, so I hope the above explanation and code helps others, especially as I have learnt so much from this site and still consider myself a beginner!

Although this is the answer to my specific question, I have selected szatmary's answer as the accepted one as it is the most comprehensive.

You can use the split() function to break input on the basis of line break.

I am using Retrofit 1.9 to obtain a XML.

public class ServicioConexionRetrofitXML {

    public static final String API_BASE_URL = new GestorPreferencias().getPreferencias().getHost();
    public static final long tiempoMaximoRespuestaSegundos = 60;
    public static final long tiempoMaximoLecturaSegundos = 100;
    public static final OkHttpClient clienteOkHttp = new OkHttpClient();


    private static RestAdapter.Builder builder = new RestAdapter.Builder().
            setEndpoint(API_BASE_URL).
            setClient(new OkClient(clienteOkHttp)).setConverter(new SimpleXMLConverter());


    public static <S> S createService(Class<S> serviceClass) {
        clienteOkHttp.setConnectTimeout(tiempoMaximoRespuestaSegundos, TimeUnit.SECONDS);
        clienteOkHttp.setReadTimeout(tiempoMaximoLecturaSegundos, TimeUnit.SECONDS);
        RestAdapter adapter = builder.build();
        return adapter.create(serviceClass);
    }

}

If you are using Retrofit 1.9.0 and okhttp 2.6.0, add to your Gradle file.

    compile 'com.squareup.retrofit:retrofit:1.9.0'
    compile 'com.squareup.okhttp:okhttp:2.6.0'
    // Librería de retrofit para XML converter (Simple) Se excluyen grupos para que no entre
    // en conflicto.
    compile('com.squareup.retrofit:converter-simplexml:1.9.0') {
        exclude group: 'xpp3', module: 'xpp3'
        exclude group: 'stax', module: 'stax-api'
        exclude group: 'stax', module: 'stax'
    }

Note: If you need to fetch a JSON, just remove from code above.

.setConverter(new SimpleXMLConverter())

I solved it putting a old version of maven (2.x), using brew:

brew uninstall maven
brew tap homebrew/versions 
brew install maven2

Yes, you can target both x86 and x64 with the same code base in the same project. In general, things will Just Work if you create the right solution configurations in VS.NET (although P/Invoke to entirely unmanaged DLLs will most likely require some conditional code): the items that I found to require special attention are:

• References to outside managed assemblies with the same name but their own specific bitness (this also applies to COM interop assemblies)
• The MSI package (which, as has already been noted, will need to target either x86 or x64)
• Any custom .NET Installer Class-based actions in your MSI package

The assembly reference issue can't be solved entirely within VS.NET, as it will only allow you to add a reference with a given name to a project once. To work around this, edit your project file manually (in VS, right-click your project file in the Solution Explorer, select Unload Project, then right-click again and select Edit). After adding a reference to, say, the x86 version of an assembly, your project file will contain something like:

<Reference Include="Filename, ..., processorArchitecture=x86">
  <HintPath>C:\path\to\x86\DLL</HintPath>
</Reference>

Wrap that Reference tag inside an ItemGroup tag indicating the solution configuration it applies to, e.g:

<ItemGroup Condition=" '$(Configuration)|$(Platform)' == 'Debug|x86' ">
   <Reference ...>....</Reference>
</ItemGroup>

Then, copy and paste the entire ItemGroup tag, and edit it to contain the details of your 64-bit DLL, e.g.:

<ItemGroup Condition=" '$(Configuration)|$(Platform)' == 'Debug|x64' ">
  <Reference Include="Filename, ..., processorArchitecture=AMD64">
     <HintPath>C:\path\to\x64\DLL</HintPath>
   </Reference>
</ItemGroup>

After reloading your project in VS.NET, the Assembly Reference dialog will be a bit confused by these changes, and you may encounter some warnings about assemblies with the wrong target processor, but all your builds will work just fine.

Solving the MSI issue is up next, and unfortunately this will require a non-VS.NET tool: I prefer Caphyon's Advanced Installer for that purpose, as it pulls off the basic trick involved (create a common MSI, as well as 32-bit and 64-bit specific MSIs, and use an .EXE setup launcher to extract the right version and do the required fixups at runtime) very, very well.

You can probably achieve the same results using other tools or the Windows Installer XML (WiX) toolset, but Advanced Installer makes things so easy (and is quite affordable at that) that I've never really looked at alternatives.

One thing you may still require WiX for though, even when using Advanced Installer, is for your .NET Installer Class custom actions. Although it's trivial to specify certain actions that should only run on certain platforms (using the VersionNT64 and NOT VersionNT64 execution conditions, respectively), the built-in AI custom actions will be executed using the 32-bit Framework, even on 64-bit machines.

This may be fixed in a future release, but for now (or when using a different tool to create your MSIs that has the same issue), you can use WiX 3.0's managed custom action support to create action DLLs with the proper bitness that will be executed using the corresponding Framework.

Edit: as of version 8.1.2, Advanced Installer correctly supports 64-bit custom actions. Since my original answer, its price has increased quite a bit, unfortunately, even though it's still extremely good value when compared to InstallShield and its ilk...

Edit: If your DLLs are registered in the GAC, you can also use the standard reference tags this way (SQLite as an example):

<ItemGroup Condition="'$(Platform)' == 'x86'">
    <Reference Include="System.Data.SQLite, Version=1.0.80.0, Culture=neutral, PublicKeyToken=db937bc2d44ff139, processorArchitecture=x86" />
</ItemGroup>
<ItemGroup Condition="'$(Platform)' == 'x64'">
    <Reference Include="System.Data.SQLite, Version=1.0.80.0, Culture=neutral, PublicKeyToken=db937bc2d44ff139, processorArchitecture=AMD64" />
</ItemGroup>

The condition is also reduced down to all build types, release or debug, and just specifies the processor architecture.

Array.prototype.swap = function(a, b) {
  var temp = this[a];
  this[a] = this[b];
  this[b] = temp;
};

Usage:

var myArray = [0,1,2,3,4...];
myArray.swap(4,1);

I agree with Laura and the SimpleDateFormat which is the best way to manage Dates in java. You can set the pattern and the locale. Plus you can have a look at this wikipedia article about Date in the world -there are not so many different ways to use it; typically USA / China / rest of the world -

- (void)applicationDidEnterBackground:(UIApplication *)application
{
   UILocalNotification *notification = [[UILocalNotification alloc]init];
   notification.repeatInterval = NSDayCalendarUnit;
   [notification setAlertBody:@"Hello world"];
   [notification setFireDate:[NSDate dateWithTimeIntervalSinceNow:1]];
   [notification setTimeZone:[NSTimeZone  defaultTimeZone]];
   [application setScheduledLocalNotifications:[NSArray arrayWithObject:notification]];
}

This is worked, but in iOS 8.0 and later, your application must register for user notifications using -[UIApplication registerUserNotificationSettings:] before being able to schedule and present UILocalNotifications, do not forget this.

its anything other than the data itself, ie tcp flags, headers, crc, fcs etc..

Spring cannot instantiate your TestController because its only constructor requires a parameter. You can add a no-arg constructor or you add @Autowired annotation to the constructor:

@Autowired
public TestController(KeeperClient testClient) {
    TestController.testClient = testClient;
}

In this case, you are explicitly telling Spring to search the application context for a KeeperClient bean and inject it when instantiating the TestControlller.

This is a highly inefficient way of doing it. You can use the merge statement and then there's no need for cursors, looping or (if you can do without) PL/SQL.

MERGE INTO studLoad l
USING ( SELECT studId, studName FROM student ) s
ON (l.studId = s.studId)
WHEN MATCHED THEN
  UPDATE SET l.studName = s.studName
   WHERE l.studName != s.studName
WHEN NOT MATCHED THEN 
INSERT (l.studID, l.studName)
VALUES (s.studId, s.studName)

Make sure you commit, once completed, in order to be able to see this in the database.

To actually answer your question I would do it something like as follows. This has the benefit of doing most of the work in SQL and only updating based on the rowid, a unique address in the table.

It declares a type, which you place the data within in bulk, 10,000 rows at a time. Then processes these rows individually.

However, as I say this will not be as efficient as merge.

declare

   cursor c_data is
    select b.rowid as rid, a.studId, a.studName
      from student a
      left outer join studLoad b
        on a.studId = b.studId
       and a.studName <> b.studName
           ;

   type t__data is table of c_data%rowtype index by binary_integer;
   t_data t__data;

begin

   open c_data;
   loop
      fetch c_data bulk collect into t_data limit 10000;

      exit when t_data.count = 0;

      for idx in t_data.first .. t_data.last loop
         if t_data(idx).rid is null then
            insert into studLoad (studId, studName)
            values (t_data(idx).studId, t_data(idx).studName);
         else
            update studLoad
               set studName = t_data(idx).studName
             where rowid = t_data(idx).rid
                   ;
         end if;
      end loop;

   end loop;
   close c_data;

end;

Here is another way, by rotating element with the scrollbar for 180deg, wrapping it's content into another element, and rotating that wrapper for -180deg. Check the snippet below

Paulo's help lead me to the solution. It was a combination of the following:

• the password contained a dollar sign
• I was trying to connect from a Linux shell

The bash shell treats the dollar sign as a special character for expansion to an environment variable, so we need to escape it with a backslash. Incidentally, we don't have to do this in the case where the dollar sign is the final character of the password.

As an example, if your password is "pas$word", from Linux bash we must connect as follows:

# mysql --host=192.168.233.142 --user=root --password=pas\$word

I had no luck until I installed the 2010 version link here: https://www.microsoft.com/en-us/download/details.aspx?id=13255

I tried installing the 32 bit version, it still errored, so I uninstalled it and installed the 64 bit version and it started working.

Alternative to @HostListener and scroll output on the element I would suggest using fromEvent from RxJS since you can chain it with filter() and distinctUntilChanges() and can easily skip flood of potentially redundant events (and change detections).

Here is a simple example:

// {static: true} can be omitted if you don't need this element/listener in ngOnInit
@ViewChild('elementId', {static: true}) el: ElementRef;

// ...

fromEvent(this.el.nativeElement, 'scroll')
  .pipe(
    // Is elementId scrolled for more than 50 from top?
    map((e: Event) => (e.srcElement as Element).scrollTop > 50),
    // Dispatch change only if result from map above is different from previous result
    distinctUntilChanged());

I've been trying to do something very similar but not using the nodes. However, my xml structure is a little different.

You have it like this:

<Metrics>
    <Metric id="TransactionCleanupThread.RefundOldTrans" type="timer" ...>

If it were like this instead:

<Metrics>
    <Metric>
        <id>TransactionCleanupThread.RefundOldTrans</id>
        <type>timer</type>
        .
        .
        .

Then you could simply use this SQL statement.

SELECT
    Sqm.SqmId,
    Data.value('(/Sqm/Metrics/Metric/id)[1]', 'varchar(max)') as id,
    Data.value('(/Sqm/Metrics/Metric/type)[1]', 'varchar(max)') AS type,
    Data.value('(/Sqm/Metrics/Metric/unit)[1]', 'varchar(max)') AS unit,
    Data.value('(/Sqm/Metrics/Metric/sum)[1]', 'varchar(max)') AS sum,
    Data.value('(/Sqm/Metrics/Metric/count)[1]', 'varchar(max)') AS count,
    Data.value('(/Sqm/Metrics/Metric/minValue)[1]', 'varchar(max)') AS minValue,
    Data.value('(/Sqm/Metrics/Metric/maxValue)[1]', 'varchar(max)') AS maxValue,
    Data.value('(/Sqm/Metrics/Metric/stdDeviation)[1]', 'varchar(max)') AS stdDeviation,
FROM Sqm

To me this is much less confusing than using the outer apply or cross apply.

I hope this helps someone else looking for a simpler solution!

Most of the time this issue is fixed by simply visiting the Settings -> Permalink page in the WordPress admin and click Save (as several other answers already pointed out). When this page is accessed, WordPress rewrites the directives in the .htaccess file which magically fixes the issue. The issue often happens after moving a site (the site breaks because the .htaccess gets left behind or the settings need to be updated).

If WordPress doesn't have the right permissions to write the .htaccess file, a notice will appear at the top of the page and further instructions at the bottom when the settings are saved. In this case you need to edit the .htaccess file yourself or, better, to fix the permissions on that file. The file is at the root of the WordPress installation. cd into the directory and sudo chmod 644 .htaccess. You might also want to check if the file belongs to the right group and change that is needed with chown. Ask your hosting provider if you don't know how to do that.

If you are on shared hosting that's probably all you can do. If you still have the issue you might want to talk to you hosting provider's support. Otherwise, make sure the use of .htaccess files is enabled on the server, as @georgeos already suggested. Note that httpd.conf is not always used (Ubuntu indicates it is deprecated but the official Apache docs still says it is often the main configuration file). /etc/httpd/conf/httpd.conf and /etc/apache2/apache2.conf seem to be the most common places for this file. Find the block for the public folder, usually <Directory /var/www/> and make sure that the AllowOverride directive is set to All. If it is set to None, your .htaccess file is simply ignored by the server.

Who needs trig when you have complex numbers:

#include <complex.h>
#include <math.h>

#define PI      3.14159265358979323846

typedef complex double Point;

Point point_on_circle ( double radius, double angle_in_degrees, Point centre )
{
    return centre + radius * cexp ( PI * I * ( angle_in_degrees  / 180.0 ) );
}

This calls exactly for the using the Maven JAR Plugin

For example, if you want to exclude everything under src/test/resources/ from the final jar, put this:

<build>

        <plugins>
            <!-- configure JAR build -->
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-jar-plugin</artifactId>
                <version>2.3.1</version>
                <configuration>
                    <excludes>
                        <exclude>src/test/resources/**</exclude>
                    </excludes>
                </configuration>
            </plugin>

...

Files under src/test/resources/ will still be available on class-path, they just won't be in resulting JAR.

Use Minted.

It's a package that facilitates expressive syntax highlighting in LaTeX using the powerful Pygments library. The package also provides options to customize the highlighted source code output using fancyvrb.

It's much more evolved and customizable than any other package!

Uncheck "Power Save Mode" in "File" tab

I am using Android Studio 3.0 and was facing the same problem. I add this to my gradle:

multiDexEnabled true

And it worked!

Example

android {
    compileSdkVersion 27
    buildToolsVersion '27.0.1'
    defaultConfig {
        applicationId "com.xx.xxx"
        minSdkVersion 15
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        multiDexEnabled true //Add this
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            shrinkResources true
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

And clean the project.

Actually, ojdbc14.jar doesn't really say anything about the real version of the driver (see JDBC Driver Downloads), except that it predates Oracle 11g. In such situation, you should provide the exact version.

Anyway, I think you'll find some explanation in What is going on with DATE and TIMESTAMP? In short, they changed the behavior in 9.2 drivers and then again in 11.1 drivers.

This might explain the differences you're experiencing (and I suggest using the most recent version i.e. the 11.2 drivers).

It is no longer possible... allegedly. If you have a Facebook or Instagram dedicated contact (because you work in either a big agency or with a big client) it may potentially be possible depending on your use case, but it's highly discouraged.

Before December 2019:

It is now "possible":

https://developers.facebook.com/docs/instagram-api/content-publishing

The Content Publishing API is a subset of Instagram Graph API endpoints that allow you to publish media objects. Publishing media objects with this API is a two step process — you first create a media object container, then publish the container on your Business Account.

Its worth noting that "The Content Publishing API is in closed beta with Facebook Marketing Partners and Instagram Partners only. We are not accepting new applicants at this time." from https://stackoverflow.com/a/49677468/445887

These examples are minified because StackOverflow has a maximum character limit and links to external code are discouraged since links can break.

There are multiple plugins if you look: Bootstrap Sortable, Bootstrap Table or DataTables.
