Programs & Examples On #Sql standards

I'd recommend using some work queue using, for example, the excellent Gearman, which will provide you with a great way to dispatch background jobs, and asynchronously get their result once they're processed.

The advantage of this, used heavily at Digg (among many others) is that it provides a strong, scalable and robust way to make workers in any language to speak with clients in any language.

I think your INSERT statement is wrong, see correct syntax: http://dev.mysql.com/doc/refman/5.1/en/insert.html

edit: as Andrew already pointed out...

jQuery has a resize event handler which you can attach to the window, .resize(). So, if you put $(window).resize(function(){/* YOUR CODE HERE */}) then your code will be run every time the window is resized.

So, what you want is to run the code after the first page load and whenever the window is resized. Therefore you should pull the code into its own function and run that function in both instances.

// This function positions the footer based on window size
function positionFooter(){
    var $containerHeight = $(window).height();
    if ($containerHeight <= 818) {
        $('.footer').css({
            position: 'static',
            bottom: 'auto',
            left: 'auto'
        });
    }
    else {
        $('.footer').css({
            position: 'absolute',
            bottom: '3px',
            left: '0px'
        });
    } 
}

$(document).ready(function () {
    positionFooter();//run when page first loads
});

$(window).resize(function () {
    positionFooter();//run on every window resize
});

See: Cross-browser window resize event - JavaScript / jQuery

var newDate = new Date();
newDate.setTime(unixtime*1000);
dateString = newDate.toUTCString();

Where unixtime is the time returned by your sql db. Here is a fiddle if it helps.

For example, using it for the current time:

document.write( new Date().toUTCString() );

In Spring Data you simply define an update query if you have the ID

  @Repository
  public interface CustomerRepository extends JpaRepository<Customer , Long> {

     @Query("update Customer c set c.name = :name WHERE c.id = :customerId")
     void setCustomerName(@Param("customerId") Long id, @Param("name") String name);

  }

Some solutions claim to use Spring data and do JPA oldschool (even in a manner with lost updates) instead.

Sessions would be the only good way, you could also use GET/POST but that would be potentially insecure.

There are various management views built into the product. On SQL 2000 you'd use sysprocesses. On SQL 2K5 there are more views like sys.dm_exec_connections, sys.dm_exec_sessions and sys.dm_exec_requests.

There are also procedures like sp_who that leverage these views. In 2K5 Management Studio you also get Activity Monitor.

And last but not least there are community contributed scripts like the Who Is Active by Adam Machanic.

When using Visual Studio Code on Linux/Windows, you can use CTRL + PAGE_UP to switch to the previous tab, and CTRL + PAGE_DN to switch to the next tab. You also have the ability to switch to tabs based on their (non-zero relative) index. You can do so, by pressing and holding ALT , followed by a number (1 through 9).

PHP provides two types of array.

• normal array
• SplFixedArray

normal array : This array is dynamic.

SplFixedArray : this is a standard php library which provides the ability to create array of fix size.

Each class will use its own classloader to load other classes. So if ClassA.class references ClassB.class then ClassB needs to be on the classpath of the classloader of ClassA, or its parents.

The thread context classloader is the current classloader for the current thread. An object can be created from a class in ClassLoaderC and then passed to a thread owned by ClassLoaderD. In this case the object needs to use Thread.currentThread().getContextClassLoader() directly if it wants to load resources that are not available on its own classloader.

where are you trying to return the value? to console in dev tools is better for debugging

<script type = 'text/javascript'>
var ask = confirm('".$message."');
function answer(){
  if(ask==false){
    return false;     
  } else {
    return true;
  }
}
console.log("ask : ", ask);
console.log("answer : ", answer());
</script>

REQUEST:

 $.ajax({

            data: JSON.stringify(somejson),
            dataType: "json",
            success: function (response) {
                var resp = JSON.parse(response)
                alert(resp.status);
            },

            }
        });

RESPONSE:

You may do it simply using python comprehension.

arr = [
    ['a', 'b', 'c'], 
    ['d', 'e', 'f'], 
    ['g', 'h', 'i']
]
transpose = [[arr[y][x] for y in range(len(arr))] for x in range(len(arr[0]))]

if The wampserver Version 2.5 then change apache configuration as

httpd.conf (apache configuration file): From

#LoadModule rewrite_module modules/mod_rewrite.so** 

To ,delete the #

LoadModule rewrite_module modules/mod_rewrite.so** 

this working fine to me

Multiple Approch can be applied:

• Class Based Approch: use local state and define existing field with default value:

constructor(props) {
    super(props);
    this.state = {
      value:''
    }
  }
<input type='text'
                  name='firstName'
                  value={this.state.value}
                  className="col-12"
                  onChange={this.onChange}
                  placeholder='Enter First name' />

• Using Hooks React > 16.8 in functional style components:

[value, setValue] = useState('');
<input type='text'
                  name='firstName'
                  value={value}
                  className="col-12"
                  onChange={this.onChange}
                  placeholder='Enter First name' />

• If Using propTypes and providing Default Value for propTypes in case of HOC component in functional style.

 HOC.propTypes = {
    value       : PropTypes.string
  }
  HOC.efaultProps = {
    value: ''
  }

function HOC (){

  return (<input type='text'
                  name='firstName'
                  value={this.props.value}
                  className="col-12"
                  onChange={this.onChange}
                  placeholder='Enter First name' />)

}

.git/HEAD contains the path of the current ref, the working directory is using as HEAD.

To clarify for future reference, a2enmod, as is suggested in several answers above, is for Debian/Ubuntu. Red Hat does not use this to enable Apache modules - instead it uses LoadModule statements in httpd.conf.

Nothing like these two lines appears in Mike Williams' tutorial:

    wait = true;
    setTimeout("wait = true", 2000);

Here's a Version 3 port:

http://acleach.me.uk/gmaps/v3/plotaddresses.htm

The relevant bit of code is

  // ====== Geocoding ======
  function getAddress(search, next) {
    geo.geocode({address:search}, function (results,status)
      { 
        // If that was successful
        if (status == google.maps.GeocoderStatus.OK) {
          // Lets assume that the first marker is the one we want
          var p = results[0].geometry.location;
          var lat=p.lat();
          var lng=p.lng();
          // Output the data
            var msg = 'address="' + search + '" lat=' +lat+ ' lng=' +lng+ '(delay='+delay+'ms)<br>';
            document.getElementById("messages").innerHTML += msg;
          // Create a marker
          createMarker(search,lat,lng);
        }
        // ====== Decode the error status ======
        else {
          // === if we were sending the requests to fast, try this one again and increase the delay
          if (status == google.maps.GeocoderStatus.OVER_QUERY_LIMIT) {
            nextAddress--;
            delay++;
          } else {
            var reason="Code "+status;
            var msg = 'address="' + search + '" error=' +reason+ '(delay='+delay+'ms)<br>';
            document.getElementById("messages").innerHTML += msg;
          }   
        }
        next();
      }
    );
  }

LINQ is very effective and easy to use on Lists rather than DataTable. I can see the above answers have a loop(for, foreach), which I will not prefer.

So the best thing to select a perticular column from a DataTable is just use a DataView to filter the column and use it as you want.

Find it here how to do this.

DataView dtView = new DataView(dtYourDataTable);
DataTable dtTableWithOneColumn= dtView .ToTable(true, "ColumnA");

Now the DataTable dtTableWithOneColumn contains only one column(ColumnA).

if you want to have your port as a variable, you can write php like this:

$username = user;
$password = pw;
$host = 127.0.0.1;
$database = dbname;
$port = 3308; 

$conn = mysql_connect($host.':'.$port, $username, $password);
$db=mysql_select_db($database,$conn);

you can follow BaseAdapter and create your custome Xml file and bind it with you BaseAdpter and populate it with Listview see here need to change xml file as Require.

If this div is a function I suggest use cursor:pointer in your style like style="cursor:pointer" and can use onclick function.

like this

<div onclick="myfunction()" style="cursor:pointer"></div>

but I suggest you use a JS framework like jquery or extjs

Apache HttpClient 4.5 supports accepting self-signed certificates:

SSLContext sslContext = SSLContexts.custom()
    .loadTrustMaterial(new TrustSelfSignedStrategy())
    .build();
SSLConnectionSocketFactory socketFactory =
    new SSLConnectionSocketFactory(sslContext);
Registry<ConnectionSocketFactory> reg =
    RegistryBuilder.<ConnectionSocketFactory>create()
    .register("https", socketFactory)
    .build();
HttpClientConnectionManager cm = new PoolingHttpClientConnectionManager(reg);        
CloseableHttpClient httpClient = HttpClients.custom()
    .setConnectionManager(cm)
    .build();
HttpGet httpGet = new HttpGet(url);
CloseableHttpResponse sslResponse = httpClient.execute(httpGet);

This builds an SSL socket factory which will use the TrustSelfSignedStrategy, registers it with a custom connection manager then does an HTTP GET using that connection manager.

I agree with those who chant "don't do this in production", however there are use-cases for accepting self-signed certificates outside production; we use them in automated integration tests, so that we're using SSL (like in production) even when not running on the production hardware.

From "Find duplicate rows with PostgreSQL" here's smart solution:

select * from (
  SELECT id,
  ROW_NUMBER() OVER(PARTITION BY column1, column2 ORDER BY id asc) AS Row
  FROM tbl
) dups
where 
dups.Row > 1

Try this:

Select u.[username]
      ,u.[ip]
      ,q.[time_stamp]
From [users] As u
Inner Join (
    Select [username]
          ,max(time_stamp) as [time_stamp]
    From [users]
    Group By [username]) As [q]
On u.username = q.username
And u.time_stamp = q.time_stamp

If your panel is 'not opaque' (transparent) you wont see your background color.

You've got about these four possibilities:

• Remote files. This needs allow_url_fopen to be enabled in php.ini, but it's the easiest method.

• Alternatively you could use cURL if your PHP installation supports it. There's even an example.

• And if you really want to do it manually use the HTTP module.

• Don't even try to use sockets directly.

For perfomance, try itertools.

The itertools module standardizes a core set of fast, memory efficient tools that are useful by themselves or in combination. Together, they form an “iterator algebra” making it possible to construct specialized tools succinctly and efficiently in pure Python.

See itertools.ifilter or imap.

itertools.ifilter(predicate, iterable)

Make an iterator that filters elements from iterable returning only those for which the predicate is True

'JavaType' works !! I was trying to unmarshall (deserialize) a List in json String to ArrayList java Objects and was struggling to find a solution since days.
Below is the code that finally gave me solution. Code:

JsonMarshallerUnmarshaller<T> {
    T targetClass;

    public ArrayList<T> unmarshal(String jsonString) {
        ObjectMapper mapper = new ObjectMapper();

        AnnotationIntrospector introspector = new JacksonAnnotationIntrospector();
        mapper.getDeserializationConfig()
            .withAnnotationIntrospector(introspector);

        mapper.getSerializationConfig()
            .withAnnotationIntrospector(introspector);
        JavaType type = mapper.getTypeFactory().
            constructCollectionType(
                ArrayList.class, 
                targetclass.getClass());

        try {
            Class c1 = this.targetclass.getClass();
            Class c2 = this.targetclass1.getClass();
            ArrayList<T> temp = (ArrayList<T>) 
                mapper.readValue(jsonString,  type);
            return temp ;
        } catch (JsonParseException e) {
            e.printStackTrace();
        } catch (JsonMappingException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

        return null ;
    }  
}

The backslash (\) is an escape character in Javascript (along with a lot of other C-like languages). This means that when Javascript encounters a backslash, it tries to escape the following character. For instance, \n is a newline character (rather than a backslash followed by the letter n).

In order to output a literal backslash, you need to escape it. That means \\ will output a single backslash (and \\\\ will output two, and so on). The reason "aa ///\" doesn't work is because the backslash escapes the " (which will print a literal quote), and thus your string is not properly terminated. Similarly, "aa ///\\\" won't work, because the last backslash again escapes the quote.

Just remember, for each backslash you want to output, you need to give Javascript two.

This is something you solve in the "controller", which is the point of logicless templating.

// some function that retreived data through ajax
function( view ){

   if ( !view.avatar ) {
      // DEFAULTS can be a global settings object you define elsewhere
      // so that you don't have to maintain these values all over the place
      // in your code.
      view.avatar = DEFAULTS.AVATAR;
   }

   // do template stuff here

}

This is actually a LOT better then maintaining image url's or other media that might or might not change in your templates, but takes some getting used to. The point is to unlearn template tunnel vision, an avatar img url is bound to be used in other templates, are you going to maintain that url on X templates or a single DEFAULTS settings object? ;)

Another option is to do the following:

// augment view
view.hasAvatar = !!view.avatar;
view.noAvatar = !view.avatar;

And in the template:

{{#hasAvatar}}
    SHOW AVATAR
{{/hasAvatar}}
{{#noAvatar}}
    SHOW DEFAULT
{{/noAvatar}}

But that's going against the whole meaning of logicless templating. If that's what you want to do, you want logical templating and you should not use Mustache, though do give it yourself a fair chance of learning this concept ;)

Ubuntu 20.04:

Option 1 - set up a gem installation directory for your user account

For bash (for zsh, we would use .zshrc of course)

echo '# Install Ruby Gems to ~/gems' >> ~/.bashrc
echo 'export GEM_HOME="$HOME/gems"' >> ~/.bashrc
echo 'export PATH="$HOME/gems/bin:$PATH"' >> ~/.bashrc
source ~/.bashrc

Option 2 - use snap

Uninstall the apt-version (ruby-full) and reinstall it with snap

sudo apt-get remove ruby
sudo snap install ruby --classic

I think the simplest way is:

Create a new list and add unique item.

Example:

        class MyList{
    int id;
    string date;
    string email;
    }
    
    List<MyList> ml = new Mylist();

ml.Add(new MyList(){
id = 1;
date = "2020/09/06";
email = "zarezadeh@gmailcom"
});

ml.Add(new MyList(){
id = 2;
date = "2020/09/01";
email = "zarezadeh@gmailcom"
});

 List<MyList> New_ml = new Mylist();

foreach (var item in ml)
                {
                    if (New_ml.Where(w => w.email == item.email).SingleOrDefault() == null)
                    {
                        New_ml.Add(new MyList()
                        {
                          id = item.id,
     date = item.date,
               email = item.email
                        });
                    }
                }

Here's a solution that's part of the standard library:

from distutils.dir_util import copy_tree
copy_tree("/a/b/c", "/x/y/z")

I had the same problem due to copying and pasting code from a Microsoft Word Document. Seems there was a slightly different type of dash - character used, when I replaced the longer dash character with the correct - the program executed properly

This question has been answered already several times, I'll short summary for each of them, an example and insights as of September 2019:

• Normalize.css - as the name suggests, it normalizes styles in the browsers for their user agents, i.e. makes them the same across all browsers due to the reason by default they're slightly different.

Example: <h1> tag inside <section> by default Google Chrome will make smaller than the "expected" size of <h1> tag. Microsoft Edge on the other hand is making the "expected" size of <h1> tag. Normalize.css will make it consistent.

Current status: the npm repository shows that normalize.css package has currently more than 500k downloads per week. GitHub stars in the project of the repository are more than 36k.

• Reset CSS - as the name suggests, it resets all styles, i.e. it removes all browser's user agent styles.

Example: it would do something like that below:

html, body, div, span, ..., audio, video {  
   margin: 0;  
   padding: 0;  
   border: 0;  
   font-size: 100%;  
   font: inherit;  
   vertical-align: baseline; 
}

Current status: it's much less popular than Normalize.css, the reset-css package shows it's something around 26k downloads per week. GitHub stars are only 200, as it can be noticed from the project's repository.

You can use LINQ to DataSet/DataTable

var rows = dt.AsEnumerable()
               .Where(r=> r.Field<int>("ID") == 5);

Since each row has a unique ID, you should use Single/SingleOrDefault which would throw exception if you get multiple records back.

DataRow dr = dt.AsEnumerable()
               .SingleOrDefault(r=> r.Field<int>("ID") == 5);

(Substitute int for the type of your ID field)

Use this Code in code behind

Div_Card.Style["background-image"] = Page.ResolveUrl(Session["Img_Path"].ToString());

My small contribution :

What is a transient field?
Basically, any field modified with the transient keyword is a transient field.

Why are transient fields needed in Java?
The transient keyword gives you some control over the serialization process and allows you to exclude some object properties from this process. The serialization process is used to persist Java objects, mostly so that their states can be preserved while they are transferred or inactive. Sometimes, it makes sense not to serialize certain attributes of an object.

Which fields should you mark transient?
Now we know the purpose of the transient keyword and transient fields, it's important to know which fields to mark transient. Static fields aren't serialized either, so the corresponding keyword would also do the trick. But this might ruin your class design; this is where the transient keyword comes to the rescue. I try not to allow fields whose values can be derived from others to be serialized, so I mark them transient. If you have a field called interest whose value can be calculated from other fields (principal, rate & time), there is no need to serialize it.

Another good example is with article word counts. If you are saving an entire article, there's really no need to save the word count, because it can be computed when article gets "deserialized." Or think about loggers; Logger instances almost never need to be serialized, so they can be made transient.

Go to proxy settings in Firefox and choose "Use system proxy" but be sure to check if there is no exception for localhost in "no proxy for" field.

breast$class <- as.numeric(as.character(breast$class))

If you have many columns to convert to numeric

indx <- sapply(breast, is.factor)
breast[indx] <- lapply(breast[indx], function(x) as.numeric(as.character(x)))

Another option is to use stringsAsFactors=FALSE while reading the file using read.table or read.csv

Just in case, other options to create/change columns

 breast[,'class'] <- as.numeric(as.character(breast[,'class']))

or

 breast <- transform(breast, class=as.numeric(as.character(breast)))

You can also create a new document from MongoDB compass or using command and set the specific _id value that you want.

td[rowspan] {
  vertical-align: top;
  text-align: left;
}

See: CSS attribute selectors.

I would rather go with regex.

If your code is as follows,

vendors = [
    {
      Name: 'Magenic',
      ID: 'ABC'
     },
    {
      Name: 'Microsoft',
      ID: 'DEF'
    }
];

I would recommend

/"Name":"Magenic"/.test(JSON.stringify(vendors))

Nevermind everyone, I managed to solve the problem by adding an additional div between the wrapper and box.

CSS

#wrapper {
    position: absolute;
}

#middle {
    border-radius: 100px;
    overflow: hidden; 
}

#box {
    width: 300px; height: 300px;
    background-color: #cde;
}

HTML

<div id="wrapper">
    <div id="middle">
        <div id="box"></div>
    </div>
</div>

Thanks everyone who helped!

You can input json array to this function get output as string array

example Input - { "gender" : ["male", "female"] }

output - {"male", "female"}

private String[] convertToStringArray(Object array) throws Exception {
   return StringUtils.stripAll(array.toString().substring(1, array.toString().length()-1).split(","));
}

Thanks to the previous answers you knew how to save/download a request.

For people who are asking for a way to save/export the response you can use the arrow beside the "Send" button, click "Send and Download" to get the response in .json

Try this:

If [ $a -lt 4 ] || [ $a -gt 64 ] ; then \n
     Something something \n
elif [ $a -gt 4 ] || [ $a -lt 64 ] ; then \n
     Something something \n
else \n
    Yes it works for me :) \n

Heap memory

The heap memory is the runtime data area from which the Java VM allocates memory for all class instances and arrays. The heap may be of a fixed or variable size. The garbage collector is an automatic memory management system that reclaims heap memory for objects.

• Eden Space: The pool from which memory is initially allocated for most objects.

• Survivor Space: The pool containing objects that have survived the garbage collection of the Eden space.

• Tenured Generation or Old Gen: The pool containing objects that have existed for some time in the survivor space.

Non-heap memory

Non-heap memory includes a method area shared among all threads and memory required for the internal processing or optimization for the Java VM. It stores per-class structures such as a runtime constant pool, field and method data, and the code for methods and constructors. The method area is logically part of the heap but, depending on the implementation, a Java VM may not garbage collect or compact it. Like the heap memory, the method area may be of a fixed or variable size. The memory for the method area does not need to be contiguous.

• Permanent Generation: The pool containing all the reflective data of the virtual machine itself, such as class and method objects. With Java VMs that use class data sharing, this generation is divided into read-only and read-write areas.

• Code Cache: The HotSpot Java VM also includes a code cache, containing memory that is used for compilation and storage of native code.

Here's some documentation on how to use Jconsole.

Almost all of the answers on this page rely on checking a session variable's existence to validate a user login. That is absolutely fine, but it is important to consider that the PHP session state is not unique to your application if there are multiple virtual hosts/sites on the same bare metal.

If you have two PHP applications on a webserver, both checking a user's login status with a boolean flag in a session variable called 'isLoggedIn', then a user could log into one of the applications and then automagically gain access to the second without credentials.

I suspect even the most dinosaur of commercial shared hosting wouldn't let virtual hosts share the same PHP environment in such a way that this could happen across multiple customers site's (anymore), but its something to consider in your own environments.

The very simple solution is to use a session variable that identifies the app rather than a boolean flag. e.g $SESSION["isLoggedInToExample.com"].

Source: I'm a penetration tester, with a lot of experience on how you shouldn't do stuff.

var someParam = xxxxxxx;

commentbtn.click(function(){

    alert(someParam );
});

User order by with that field, and then do distinct.

ProductOrder.objects.order_by('category').values_list('category', flat=True).distinct()

Environment.GetCommandLineArgs()[0]

EASIEST way (this worked flawlessly for me) is to locally host your site at 0.0.0.0:<port_no> and to access it using mobile devices, use <local_ipv4_address>:<port_no>/<path> in browser.

• To know your local ipv4 address, just type ipconfig in cmd
• ANY device connected to the SAME network can access this url.

This will have some overhead, but technically it does answer your question:

echo abc `#Put your comment here` \
     def `#Another chance for a comment` \
     xyz, etc.

And for pipelines specifically, there is a clean solution with no overhead:

echo abc |        # Normal comment OK here
     tr a-z A-Z | # Another normal comment OK here
     sort |       # The pipelines are automatically continued
     uniq         # Final comment

See Stack Overflow question How to Put Line Comment for a Multi-line Command.

The code works for me. (after adding missing except clause / import statements)

Did you put \ in the original code?

urlToVisit = 'http://chartapi.finance.yahoo.com/instrument/1.0/' \
              + stock + '/chartdata;type=quote;range=5d/csv'

If you omit it, it could be a cause of the exception:

>>> stock = 'GOOG'
>>> urlToVisit = 'http://chartapi.finance.yahoo.com/instrument/1.0/'
>>> + stock + '/chartdata;type=quote;range=5d/csv'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: bad operand type for unary +: 'str'

BTW, string(e) should be str(e).

Is there a way to set my property as null or string.empty in order to restablish the field in the database as null.

No. Because it's non-nullable. If you want it to be nullable, you have to use Nullable<Guid> - if you didn't, there'd be no point in having Nullable<T> to start with. You've got a fundamental issue here - which you actually know, given your first paragraph. You've said, "I know if I want to achieve A, I must do B - but I want to achieve A without doing B." That's impossible by definition.

The closest you can get is to use one specific GUID to stand in for a null value - Guid.Empty (also available as default(Guid) where appropriate, e.g. for the default value of an optional parameter) being the obvious candidate, but one you've rejected for unspecified reasons.

I tried flutter clean and that didn't work for me. Then I went to wipe the emulator's data and voila, the cached issue was gone. If you have Android Studio you can launch the AVD Manager by following this Create and Manage virtual machine. Otherwise you can wipe the emulator's data using the emulator.exe command line that's included in the android SDK. Simply follow this instructions here Start the emulator from the command line.

You can do:

DataGridViewRow row = (DataGridViewRow)yourDataGridView.Rows[0].Clone();
row.Cells[0].Value = "XYZ";
row.Cells[1].Value = 50.2;
yourDataGridView.Rows.Add(row);

or:

DataGridViewRow row = (DataGridViewRow)yourDataGridView.Rows[0].Clone();
row.Cells["Column2"].Value = "XYZ";
row.Cells["Column6"].Value = 50.2;
yourDataGridView.Rows.Add(row);

Another way:

this.dataGridView1.Rows.Add("five", "six", "seven","eight");
this.dataGridView1.Rows.Insert(0, "one", "two", "three", "four");

Use the android:drawableLeft property on the EditText.

<EditText
    ...     
    android:drawableLeft="@drawable/my_icon" />

What I did was to create a canvas element that I then position in front of the image map. Then, whenever an area is moused-over, I call a func that gets the coord string for that shape and the shape-type. If it's a poly I use the coords to draw an outline on the canvas. If it's a rect I draw a rect outline. You could easily add code to deal with circles.

You could also set the opacity of the canvas to less than 100% before filling the poly/rect/circle. You could also change the reliance on a global for the canvas's context - this would mean you could deal with more than 1 image-map on the same page.

Try this along with your code.

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation  

-(void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration

once user select any option then call this method because user can be in landscape mode and then he can set only portrait mode in same view controller so automatically view should be moved to portrait mode so in that button acton call this

-(void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration

No, that would be a huge security breach. Imagine if someone could run

format c:

whenever you visted their website.

You should check MSDN for Math.Round:

The behavior of this method follows IEEE Standard 754, section 4. This kind of rounding is sometimes called rounding to nearest, or banker's rounding.

You can specify the behavior of Math.Round using an overload:

Math.Round(2.5, 0, MidpointRounding.AwayFromZero); // gives 3

Math.Round(2.5, 0, MidpointRounding.ToEven); // gives 2

vim ~/.npmrc in your Linux machine and add following. Don't forget to add registry part as this cause failure in many cases.

proxy=http://<proxy-url>:<port>
https-proxy=https://<proxy-url>:<port>
registry=http://registry.npmjs.org/

I had a very similar issue as you had. What actually worked is this:

iTotalColumns = xlWorkSheet.UsedRange.Columns.Count;
iTotalRows = xlWorkSheet.UsedRange.Rows.Count;

//These two lines do the magic.
xlWorkSheet.Columns.ClearFormats();
xlWorkSheet.Rows.ClearFormats();

iTotalColumns = xlWorkSheet.UsedRange.Columns.Count;
iTotalRows = xlWorkSheet.UsedRange.Rows.Count;

IMHO what happens is that when you delete data from Excel, it keeps on thinking that there is data in those cells, though they are blank. When I cleared the formats, it removes the blank cells and hence returns actual counts.

You can get the position of the last - with str.LastIndexOf('-'). So the next step is obvious:

var result = str.Substring(str.LastIndexOf('-') + 1);

Correction:

As Brian states below, using this on a string with no dashes will result in the same string being returned.

If it were me, I would simply create a new Controller with a Single Action and then use RenderAction in place of Partial:

// Assuming the controller is named NewController
@{Html.RenderAction("ActionName", 
                     "New", 
                      new { routeValueOne = "SomeValue" });
}

First of all, you should make an HTML form containing a file input element. You also need to set the form's enctype attribute to multipart/form-data:

<form method="post" enctype="multipart/form-data" action="/upload">
    <input type="file" name="file">
    <input type="submit" value="Submit">
</form>

Assuming the form is defined in index.html stored in a directory named public relative to where your script is located, you can serve it this way:

const http = require("http");
const path = require("path");
const fs = require("fs");

const express = require("express");

const app = express();
const httpServer = http.createServer(app);

const PORT = process.env.PORT || 3000;

httpServer.listen(PORT, () => {
  console.log(`Server is listening on port ${PORT}`);
});

// put the HTML file containing your form in a directory named "public" (relative to where this script is located)
app.get("/", express.static(path.join(__dirname, "./public")));

Once that's done, users will be able to upload files to your server via that form. But to reassemble the uploaded file in your application, you'll need to parse the request body (as multipart form data).

In Express 3.x you could use express.bodyParser middleware to handle multipart forms but as of Express 4.x, there's no body parser bundled with the framework. Luckily, you can choose from one of the many available multipart/form-data parsers out there. Here, I'll be using multer:

You need to define a route to handle form posts:

const multer = require("multer");

const handleError = (err, res) => {
  res
    .status(500)
    .contentType("text/plain")
    .end("Oops! Something went wrong!");
};

const upload = multer({
  dest: "/path/to/temporary/directory/to/store/uploaded/files"
  // you might also want to set some limits: https://github.com/expressjs/multer#limits
});


app.post(
  "/upload",
  upload.single("file" /* name attribute of <file> element in your form */),
  (req, res) => {
    const tempPath = req.file.path;
    const targetPath = path.join(__dirname, "./uploads/image.png");

    if (path.extname(req.file.originalname).toLowerCase() === ".png") {
      fs.rename(tempPath, targetPath, err => {
        if (err) return handleError(err, res);

        res
          .status(200)
          .contentType("text/plain")
          .end("File uploaded!");
      });
    } else {
      fs.unlink(tempPath, err => {
        if (err) return handleError(err, res);

        res
          .status(403)
          .contentType("text/plain")
          .end("Only .png files are allowed!");
      });
    }
  }
);

In the example above, .png files posted to /upload will be saved to uploaded directory relative to where the script is located.

In order to show the uploaded image, assuming you already have an HTML page containing an img element:

<img src="/image.png" />

you can define another route in your express app and use res.sendFile to serve the stored image:

app.get("/image.png", (req, res) => {
  res.sendFile(path.join(__dirname, "./uploads/image.png"));
});

I know that I am late to the party, but I just made a library for this that I think could really help. It is extremely simple, that's why I think you should use it. It is called TableIT.

Basic Use

To use it, first follow the download instructions on the GitHub Page.

Then import it:

import TableIt

Then make a list of lists where each inner list is a row:

table = [
    [4, 3, "Hi"],
    [2, 1, 808890312093],
    [5, "Hi", "Bye"]
]

Then all you have to do is print it:

TableIt.printTable(table)

This is the output you get:

+--------------------------------------------+
| 4            | 3            | Hi           |
| 2            | 1            | 808890312093 |
| 5            | Hi           | Bye          |
+--------------------------------------------+

Field Names

You can use field names if you want to (if you aren't using field names you don't have to say useFieldNames=False because it is set to that by default):

TableIt.printTable(table, useFieldNames=True)

From that you will get:

+--------------------------------------------+
| 4            | 3            | Hi           |
+--------------+--------------+--------------+
| 2            | 1            | 808890312093 |
| 5            | Hi           | Bye          |
+--------------------------------------------+

There are other uses to, for example you could do this:

import TableIt

myList = [
    ["Name", "Email"],
    ["Richard", "[email protected]"],
    ["Tasha", "[email protected]"]
]

TableIt.print(myList, useFieldNames=True)

From that:

+-----------------------------------------------+
| Name                  | Email                 |
+-----------------------+-----------------------+
| Richard               | [email protected] |
| Tasha                 | [email protected]    |
+-----------------------------------------------+

Or you could do:

import TableIt

myList = [
    ["", "a", "b"],
    ["x", "a + x", "a + b"],
    ["z", "a + z", "z + b"]
]

TableIt.printTable(myList, useFieldNames=True)

And from that you get:

+-----------------------+
|       | a     | b     |
+-------+-------+-------+
| x     | a + x | a + b |
| z     | a + z | z + b |
+-----------------------+

Colors

You can also use colors.

You use colors by using the color option (by default it is set to None) and specifying RGB values.

Using the example from above:

import TableIt

myList = [
    ["", "a", "b"],
    ["x", "a + x", "a + b"],
    ["z", "a + z", "z + b"]
]

TableIt.printTable(myList, useFieldNames=True, color=(26, 156, 171))

Then you will get:

Please note that printing colors might not work for you but it does works the exact same as the other libraries that print colored text. I have tested and every single color works. The blue is not messed up either as it would if using the default 34m ANSI escape sequence (if you don't know what that is it doesn't matter). Anyway, it all comes from the fact that every color is RGB value rather than a system default.

More Info

For more info check the GitHub Page

brew install wget

Homebrew is a package manager for OSX analogous to yum, apt-get, choco, emerge, etc. Be aware that you will also need to install Xcode and the Command Line Tools. Virtually anyone who uses the command line in OSX will want to install these things anyway.

If you can't or don't want to use homebrew, you could also:

Install wget manually:

curl -# "http://ftp.gnu.org/gnu/wget/wget-1.17.1.tar.xz" -o "wget.tar.xz"
tar xf wget.tar.xz
cd wget-1.17.1
./configure --with-ssl=openssl -with-libssl-prefix=/usr/local/ssl && make -j8 && make install

Or, use a bash alias:

function _wget() { curl "${1}" -o $(basename "${1}") ; };
alias wget='_wget'

Here there are two different concepts that are merged togather in your question.

First : Add Integer array into List. Code is as follows.

List<Integer[]> list = new ArrayList<>();
Integer[] intArray1 = new Integer[] {2, 4};
Integer[] intArray2 = new Integer[] {2, 5};
Integer[] intArray3 = new Integer[] {3, 3};
Collections.addAll(list, intArray1, intArray2, intArray3);

Second : Add integer value in list.

List<Integer> list = new ArrayList<>();
int x = 5
list.add(x);

Only this worked for me (AndroidX support library):

 <com.google.android.material.appbar.AppBarLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="@null"
            android:theme="@style/AppTheme.AppBarOverlay"
            android:translationZ="0.1dp"
            app:elevation="0dp">

            <androidx.appcompat.widget.Toolbar
                android:id="@+id/toolbar"
                android:layout_width="match_parent"
                android:layout_height="?attr/actionBarSize"
                android:background="@null"
                app:popupTheme="@style/AppTheme.PopupOverlay" />

        </com.google.android.material.appbar.AppBarLayout>

This code removes background in all necessary views and also removes shadow from AppBarLayout (which was a problem)

Answer was found here: remove shadow below AppBarLayout widget android

This issue occurs when someone has commited the code to develop/master and latest code has not been rebased from develop/master and you're trying to overwrite new changes to develop/master branch

Solution:

• Take a backup if you're working on feature branch and switch to master/develop branch by doing git checkout develop/master
• Do git pull
• You will get changes and merge conflicts occur when you have made changes in the same file which has not been rebased from develop/master
• Resolve the conflicts if it occurs and do git push,this should work

Here's the link I used as a guide. Hope this helps!

You can download the sample file. Just place the html you want to convert in the files folder and run. It will automatically generate the pdf file and place it in the same folder. But in your case, you can specify your html path in the htmlFileName variable.

Did you try InputMethodManager.SHOW_IMPLICIT in first window.

and for hiding in second window use InputMethodManager.HIDE_IMPLICIT_ONLY

EDIT :

If its still not working then probably you are putting it at the wrong place. Override onFinishInflate() and show/hide there.

@override
public void onFinishInflate() {
     /* code to show keyboard on startup */
    InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.showSoftInput(mUserNameEdit, InputMethodManager.SHOW_IMPLICIT);
}

The usual way to swap two items in Python is:

a, b = b, a

So it would seem to me that you would just do the same with an extended slice. However, it is slightly complicated because strings aren't mutable; so you have to convert to a list and then back to a string.
Therefore, I would do the following:

>>> s = 'badcfe'
>>> t = list(s)
>>> t[::2], t[1::2] = t[1::2], t[::2]
>>> ''.join(t)
'abcdef'

You are trying to execute the number in the ENDTIME as a command. You should also see an error like 1370306857: command not found. Instead use the arithmetic expansion:

echo "It takes $(($ENDTIME - $STARTTIME)) seconds to complete this task..."

You could also save the commands in a separate script, commands.sh, and use time command:

time commands.sh

I was having issues where the animation was always starting from the top of the page after a page refresh in the other examples.

I fixed this by not animating the css directly but rather calling window.scrollTo(); on each step:

$({myScrollTop:window.pageYOffset}).animate({myScrollTop:300}, {
  duration: 600,
  easing: 'swing',
  step: function(val) {
    window.scrollTo(0, val);
  }
});

This also gets around the html vs body issue as it's using cross-browser JavaScript.

Have a look at http://james.padolsey.com/javascript/fun-with-jquerys-animate/ for more information on what you can do with jQuery's animate function.

You could try this:

SELECT * INTO tbl_NewTableName 
FROM tbl_OldTableName
WHERE Condition1=@Condition1Value

Then run a simple delete:

DELETE FROM tbl_OldTableName
WHERE Condition1=@Condition1Value

Had the same problem and none of the above solutions worked. So, by reading carefully the logs, I found this message :

10:55:42 [Apache] Port 443 in use by ""C:\Program Files (x86)\VMware\VMware Workstation\vmware-hostd.exe" -u "C:\ProgramData\VMware\hostd\config.xml"" with PID 1908!

In my case, I had just to stop the VMWare service which was running automatically.

The key is to read carefully the message given by XAMPP Panel when started.

Hope this help!

Maybe.

Temporary tables prefixed with one # (#example) are kept on a per session basis. So if your code calls the stored procedure again while another call is running (for example background threads) then the create call will fail because it's already there.

If you're really worried use a table variable instead

DECLARE @MyTempTable TABLE 
(
   someField int,
   someFieldMore nvarchar(50)
)

This will be specific to the "instance" of that stored procedure call.

First make sure you have installed Nginx with the HTTP rewrite module. To install this we need to have pcre-library

How to install pcre library

If the above mentioned are done or if you already have them, then just add the below code in your nginx server block

  if ($host !~* ^www\.) {
    rewrite ^(.*)$ http://www.$host$1 permanent;
  }

To remove www from every request you can use

  if ($host = 'www.your_domain.com' ) {
   rewrite  ^/(.*)$  http://your_domain.com/$1  permanent;
  }

so your server block will look like

  server {
            listen       80;
            server_name  test.com;
            if ($host !~* ^www\.) {
                    rewrite ^(.*)$ http://www.$host$1 permanent;
            }
            client_max_body_size   10M;
            client_body_buffer_size   128k;

            root       /home/test/test/public;
            passenger_enabled on;
            rails_env production;

            error_page   500 502 503 504  /50x.html;
            location = /50x.html {
                    root   html;
            }

Below is the code that you may try to read a file and display in java using scanner class. Code will read the file name from user and print the data(Notepad VIM files).

import java.io.*;
import java.util.Scanner;
import java.io.*;

public class TestRead
{
public static void main(String[] input)
{
    String fname;
    Scanner scan = new Scanner(System.in);

    /* enter filename with extension to open and read its content */

    System.out.print("Enter File Name to Open (with extension like file.txt) : ");
    fname = scan.nextLine();

    /* this will reference only one line at a time */

    String line = null;
    try
    {
        /* FileReader reads text files in the default encoding */
        FileReader fileReader = new FileReader(fname);

        /* always wrap the FileReader in BufferedReader */
        BufferedReader bufferedReader = new BufferedReader(fileReader);

        while((line = bufferedReader.readLine()) != null)
        {
            System.out.println(line);
        }

        /* always close the file after use */
        bufferedReader.close();
    }
    catch(IOException ex)
    {
        System.out.println("Error reading file named '" + fname + "'");
    }
}

}

You can use Python retrying package. Retrying

It is written in Python to simplify the task of adding retry behavior to just about anything.

You can also try this for the double quotes:

JSON.stringify(sDemoString).slice(1, -1);
JSON.stringify('my string with "quotes"').slice(1, -1);

In CSS3 you have:

:nth-last-child(2)

See: https://developer.mozilla.org/en-US/docs/Web/CSS/:nth-last-child

According to https://github.com/composer/composer/issues/2119 you could extend your local composer.json to state that it provides the extension (which it doesn't really do - that's why you shouldn't publicly publish your package, only use it internally).

If you are using lombok then, you can use @NonNull annotation insted. or Just add the javax.validation dependency in pom.xml file.

Or you could just pass a string of delimited items and put it into an array or list on the receiving end.

If you, for some reason, have to stick with the hashMap, you can convert the keySet to an array and index the keys in the array to get the values in the map like so:

Object[] keys = map.keySet().toArray();

You can then access the map like:

map.get(keys[i]);

xlWorkSheet.Cells(1, 1).Borders(Excel.XlBordersIndex.xlEdgeRight).LineStyle = Excel.XlDataBarBorderType.xlDataBarBorderSolid
xlWorkSheet.Cells(1, 1).Borders(Excel.XlBordersIndex.xlEdgeLeft).LineStyle = Excel.XlDataBarBorderType.xlDataBarBorderSolid
xlWorkSheet.Cells(1, 1).Borders(Excel.XlBordersIndex.xlEdgeBottom).LineStyle = Excel.XlDataBarBorderType.xlDataBarBorderSolid
xlWorkSheet.Cells(1, 1).Borders(Excel.XlBordersIndex.xlEdgeTop).LineStyle = Excel.XlDataBarBorderType.xlDataBarBorderSolid

Alternatively you can use command line to get your SHA-1 fingerprint:

for your debug certificate you should use:

keytool -list -v -keystore C:\Users\user\.android\debug.keystore -alias androiddebugkey -storepass android -keypass android

you should change "c:\Users\user" with the path to your windows user directory

if you want to get the production SHA-1 for your own certificate, replace "C:\Users\user\.android\debug.keystore" with your custom KeyStore path and use your KeystorePass and Keypass instead of android/android.

Than declare the SHA-1 fingerprints you get to your firebase console as Damini said

you can also use:

var path = System.Web.Hosting.HostingEnvironment.MapPath("~/App_Data/myfile.txt")

if

var path = Server.MapPath("~/App_Data");
var fullpath = Path.Combine(path , "myfile.txt");

is inaccessible

Here is an updated version of Bryan's query for 2008 and later. It uses INFORMATION_SCHEMA.COLUMNS, adds variables for the table schema and table name. The column data type was added to the output. Including the column data type helps when looking for a column of a particular data type. I didn't added the column widths or anything.

For output the RAISERROR ... WITH NOWAIT is used so text will display immediately instead of all at once (for the most part) at the end like PRINT does.

SET NOCOUNT ON;

DECLARE
 @ColumnName sysname
,@DataType nvarchar(128)
,@cmd nvarchar(max)
,@TableSchema nvarchar(128) = 'dbo'
,@TableName sysname = 'TableName';

DECLARE getinfo CURSOR FOR
SELECT
     c.COLUMN_NAME
    ,c.DATA_TYPE
FROM
    INFORMATION_SCHEMA.COLUMNS AS c
WHERE
    c.TABLE_SCHEMA = @TableSchema
    AND c.TABLE_NAME = @TableName;

OPEN getinfo;

FETCH NEXT FROM getinfo INTO @ColumnName, @DataType;

WHILE @@FETCH_STATUS = 0
BEGIN
    SET @cmd = N'IF NOT EXISTS (SELECT * FROM ' + @TableSchema + N'.' + @TableName + N' WHERE [' + @ColumnName + N'] IS NOT NULL) RAISERROR(''' + @ColumnName + N' (' + @DataType + N')'', 0, 0) WITH NOWAIT;';
    EXECUTE (@cmd);

    FETCH NEXT FROM getinfo INTO @ColumnName, @DataType;
END;

CLOSE getinfo;
DEALLOCATE getinfo;

Well, not always. Using cookies, you are good. But the "can I safely rely on the id being present" urged me to extend the discussion with an important point (mostly for reference, as the visitor count of this page seems quite high).

PHP can be configured to maintain sessions by URL-rewriting, instead of cookies. (How it's good or bad (<-- see e.g. the topmost comment there) is a separate question, let's now stick to the current one, with just one side-note: the most prominent issue with URL-based sessions -- the blatant visibility of the naked session ID -- is not an issue with internal Ajax calls; but then, if it's turned on for Ajax, it's turned on for the rest of the site, too, so there...)

In case of URL-rewriting (cookieless) sessions, Ajax calls must take care of it themselves that their request URLs are properly crafted. (Or you can roll your own custom solution. You can even resort to maintaining sessions on the client side, in less demanding cases.) The point is the explicit care needed for session continuity, if not using cookies:

1. If the Ajax calls just extract URLs verbatim from the HTML (as received from PHP), that should be OK, as they are already cooked (umm, cookified).

2. If they need to assemble request URIs themselves, the session ID needs to be added to the URL manually. (Check here, or the page sources generated by PHP (with URL-rewriting on) to see how to do it.)

From OWASP.org:

Effectively, the web application can use both mechanisms, cookies or URL parameters, or even switch from one to the other (automatic URL rewriting) if certain conditions are met (for example, the existence of web clients without cookies support or when cookies are not accepted due to user privacy concerns).

From a Ruby-forum post:

When using php with cookies, the session ID will automatically be sent in the request headers even for Ajax XMLHttpRequests. If you use or allow URL-based php sessions, you'll have to add the session id to every Ajax request url.

Here is an example of Jon Adams suggestion above in order to fix a div (toolbar) to the right hand side of your page element using jQuery. The idea is to find the distance from the right hand side of the viewport to the right hand side of the page element and to keep the right hand side of the toolbar there!

HTML

<div id="pageElement"></div>
<div id="toolbar"></div>

CSS

#toolbar {
    position: fixed;
}
....

jQuery

function placeOnRightHandEdgeOfElement(toolbar, pageElement) {
    $(toolbar).css("right", $(window).scrollLeft() + $(window).width()
    - $(pageElement).offset().left
    - parseInt($(pageElement).css("borderLeftWidth"),10)
    - $(pageElement).width() + "px");
}
$(document).ready(function() {
    $(window).resize(function() {
        placeOnRightHandEdgeOfElement("#toolbar", "#pageElement");
    });
    $(window).scroll(function () { 
        placeOnRightHandEdgeOfElement("#toolbar", "#pageElement");
    });
    $("#toolbar").resize();
});

I think this is what you are looking for: jquery-html5-placeholder-fix

This solution uses feature detection (via modernizr) to determine if placeholder is supported. If not, adds support (via jQuery).

The problem is that there is no class called com.service.SempediaSearchManager on your webapp's classpath. The most likely root causes are:

• the fully qualified classname is incorrect in /WEB-INF/Sempedia-service.xml; i.e. the class name is something else,

• the class is not in your webapp's /WEB-INF/classes directory tree or a JAR file in the /WEB-INF/lib directory.

EDIT : The only other thing that I can think of is that the ClassDefNotFoundException may actually be a result of an earlier class loading / static initialization problem. Check your log files for the first stack trace, and look the nested exceptions, i.e. the "caused by" chain. [If a class load fails one time and you or Spring call Class.forName() again for some reason, then Java won't actually try to load a second time. Instead you will get a ClassDefNotFoundException stack trace that does not explain the real cause of the original failure.]

If you are still stumped, you should take Eclipse out of the picture. Create the WAR file in the form that you are eventually going to deploy it, then from the command line:

1. manually shutdown Tomcat

2. clean out your Tomcat webapp directory,

3. copy the WAR file into the webapp directory,

4. start Tomcat.

If that doesn't solve the problem directly, look at the deployed webapp directory on Tomcat to verify that the "missing" class is in the right place.

I came here looking for a quick way to check if a variable has any content in it. None of the answers here provided a full solution, so here it is:

It's enough to check if the input is '' or null, because:

Request URL .../test.php?var= results in $_GET['var'] = ''

Request URL .../test.php results in $_GET['var'] = null

isset() returns false only when the variable exists and is not set to null, so if you use it you'll get true for empty strings ('').

empty() considers both null and '' empty, but it also considers '0' empty, which is a problem in some use cases.

If you want to treat '0' as empty, then use empty(). Otherwise use the following check:

$var .'' !== '' evaluates to false only for the following inputs:

• ''
• null
• false

I use the following check to also filter out strings with only spaces and line breaks:

function hasContent($var){
    return trim($var .'') !== '';
}

I found a solution that works on jQuery 3.4.1 slim

After un-minifying, add {passive: true} to the addEventListener function on line 1567 like so:

t.addEventListener(p, a, {passive: true}))

Nothing breaks and lighthouse audits don't complain about the listeners.

In Mvc You can do it by opening Web.config file it comes under bottom of your project file

See some example in http://www.sitepoint.com/understanding-sql-joins-mysql-database/

You can use 'USING' instead of 'ON' as in the query

SELECT * FROM table1 LEFT JOIN table2 USING (id);

This would require a sort (O(n log n)) but is very simple and flexible. Another advantage is being able to use it with LINQ to SQL:

var maxObject = list.OrderByDescending(item => item.Height).First();

Note that this has the advantage of enumerating the list sequence just once. While it might not matter if list is a List<T> that doesn't change in the meantime, it could matter for arbitrary IEnumerable<T> objects. Nothing guarantees that the sequence doesn't change in different enumerations so methods that are doing it multiple times can be dangerous (and inefficient, depending on the nature of the sequence). However, it's still a less than ideal solution for large sequences. I suggest writing your own MaxObject extension manually if you have a large set of items to be able to do it in one pass without sorting and other stuff whatsoever (O(n)):

static class EnumerableExtensions {
    public static T MaxObject<T,U>(this IEnumerable<T> source, Func<T,U> selector)
      where U : IComparable<U> {
       if (source == null) throw new ArgumentNullException("source");
       bool first = true;
       T maxObj = default(T);
       U maxKey = default(U);
       foreach (var item in source) {
           if (first) {
                maxObj = item;
                maxKey = selector(maxObj);
                first = false;
           } else {
                U currentKey = selector(item);
                if (currentKey.CompareTo(maxKey) > 0) {
                    maxKey = currentKey;
                    maxObj = item;
                }
           }
       }
       if (first) throw new InvalidOperationException("Sequence is empty.");
       return maxObj;
    }
}

and use it with:

var maxObject = list.MaxObject(item => item.Height);

useState is a hook that lets you add state to a functional component. It accepts an argument which is the initial value of the state property and returns the current value of state property and a method which is capable of updating that state property.
Following is a simple example:

import React, {useState} from react    

function HookCounter {    
  const [count, stateCount]= useState(0)    
    return(    
      <div>     
        <button onClick{( ) => setCount(count+1)}> count{count}</button>    
      </div>    
    )   
 }

useState accepts the initial value of the state variable which is zero in this case and returns a pair of values. The current value of the state has been called count and a method that can update the state variable has been called as setCount.

Leading from answers from @Bozho and @aioobe, lexicographic comparisons are similar to the ordering that one might find in a dictionary.

The Java String class provides the .compareTo () method in order to lexicographically compare Strings. It is used like this "apple".compareTo ("banana").

The return of this method is an int which can be interpreted as follows:

• returns < 0 then the String calling the method is lexicographically first (comes first in a dictionary)
• returns == 0 then the two strings are lexicographically equivalent
• returns > 0 then the parameter passed to the compareTo method is lexicographically first.

More specifically, the method provides the first non-zero difference in ASCII values.

Thus "computer".compareTo ("comparison") will return a value of (int) 'u' - (int) 'a' (20). Since this is a positive result, the parameter ("comparison") is lexicographically first.

There is also a variant .compareToIgnoreCase () which will return 0 for "a".compareToIgnoreCase ("A"); for example.

Personally I prefer this method. This will overwrite the file on the destination, removes the source file and also prevent removing the source file when the copy fails.

string source = @"c:\test\SomeFile.txt";
string destination = @"c:\test\test\SomeFile.txt";

try
{
    File.Copy(source, destination, true);
    File.Delete(source);
}
catch
{
    //some error handling
}

If you want to change the Action bar title just give the following 1 line code in the onCreate() of your Activity

getActionBar().setTitle("Test");

node comes with npm installed so you should have a version of npm, however npm gets updated more frequently than node does, so you'll want to make sure it's the latest version.

sudo npm install npm -g

Test: Run npm -v. The version should be higher than 2.1.8.

npm install

Here is the Demo : http://jsfiddle.net/nyitsol/f0dv3q3z/

In my case, everything was set up correctly, but my Docker infrastructure needed more RAM. I'm using Docker for Mac, where default RAM was around 1 GB, and as MySQL uses around 1.5Gb of RAM ( and probably was crashing ??? ), changing the Docker RAM utilization level to 3-4 Gb solved the issue.

I suppose imports

import pandas as pd
import numpy as np

First append new row with NaN, NaN,... at the end of DataFrame (df).

s1 = df.iloc[0]    # copy 1st row to a new Series s1
s1[:] = np.NaN     # set all values to NaN
df2 = df.append(s1, ignore_index=True)  # add s1 to the end of df

It will create new DF df2. Maybe there is more elegant way but this works.

Now you can shift it:

df2.x2 = df2.x2.shift(1)  # shift what you want

SELECT INTO

DECLARE
   the_variable NUMBER;

BEGIN
   SELECT my_column INTO the_variable FROM my_table;
END;

Make sure that the query only returns a single row:

By default, a SELECT INTO statement must return only one row. Otherwise, PL/SQL raises the predefined exception TOO_MANY_ROWS and the values of the variables in the INTO clause are undefined. Make sure your WHERE clause is specific enough to only match one row

If no rows are returned, PL/SQL raises NO_DATA_FOUND. You can guard against this exception by selecting the result of an aggregate function, such as COUNT(*) or AVG(), where practical. These functions are guaranteed to return a single value, even if no rows match the condition.

A SELECT ... BULK COLLECT INTO statement can return multiple rows. You must set up collection variables to hold the results. You can declare associative arrays or nested tables that grow as needed to hold the entire result set.

The implicit cursor SQL and its attributes %NOTFOUND, %FOUND, %ROWCOUNT, and %ISOPEN provide information about the execution of a SELECT INTO statement.

To compare two objects you can use:

angular.equals(obj1, obj2)

It does a deep comparison and does not depend on the order of the keys See AngularJS DOCS and a little Demo

var obj1 = {
  key1: "value1",
  key2: "value2",
  key3: {a: "aa", b: "bb"}
}

var obj2 = {
  key2: "value2",
  key1: "value1",
  key3: {a: "aa", b: "bb"}
}

angular.equals(obj1, obj2) //<--- would return true

just to add to the answers here, I was using the height as a function with two options either specify the height if it is less than the window height, or set it back to auto

var windowHeight = $(window).height();
$('div#someDiv').height(function(){
    if ($(this).height() < windowHeight)
        return windowHeight;
    return 'auto';
});

I needed to center the content vertically if it was smaller than the window height or else let it scroll naturally so this is what I came up with

You can use GREATEST function with not nullable fields. If one of this values (or both) can be NULL, don't use it (result can be NULL).

select 
    if(
        fieldA is NULL, 
        if(fieldB is NULL, NULL, fieldB), /* second NULL is default value */
        if(fieldB is NULL, field A, GREATEST(fieldA, fieldB))
    ) as maxValue

You can change NULL to your preferred default value (if both values is NULL).

function htmlEscape(str){
    return str.replace(/[&<>'"]/g,x=>'&#'+x.charCodeAt(0)+';')
}

This solution uses the numerical code of the characters, for example < is replaced by <.

Although its performance is slightly worse than the solution using a map, it has the advantages:

• Not dependent on a library or DOM
• Pretty easy to remember (you don't need to memorize the 5 HTML escape characters)
• Little code
• Reasonably fast (it's still faster than 5 chained replace)

1. Data contract: It specifies that your entity class is ready for Serialization process.

2. Data members: It specifies that the particular field is part of the data contract and it can be serialized.

Have a look at py-multicast. Network module can check if an interface supports multicast (on Linux at least).

import multicast
from multicast import network

receiver = multicast.MulticastUDPReceiver ("eth0", "238.0.0.1", 1234 )
data = receiver.read()
receiver.close()

config = network.ifconfig()
print config['eth0'].addresses
# ['10.0.0.1']
print config['eth0'].multicast
#True - eth0 supports multicast
print config['eth0'].up
#True - eth0 is up

Perhaps problems with not seeing IGMP, were caused by an interface not supporting multicast?

Something like this in c# would probably do the job. Just make sure you are passing consistent units (If one point is in meters, make sure the second is also in meters)

private static double GetDistance(double x1, double y1, double x2, double y2)
{
   return Math.Sqrt(Math.Pow((x2 - x1), 2) + Math.Pow((y2 - y1), 2));
}

Called like so:

double distance = GetDistance(x1, y1, x2, y2)
if(distance <= 5)
{
   //Do stuff
}

WeakReference: objects that are only weakly referenced are collected at every GC cycle (minor or full).

SoftReference: when objects that are only softly referenced are collected depends on:

1. -XX:SoftRefLRUPolicyMSPerMB=N flag (default value is 1000, aka 1 second)

2. Amount of free memory in the heap.

   Example:

   • heap has 10MB of free space (after full GC);
   • -XX:SoftRefLRUPolicyMSPerMB=1000

   Then object which is referenced only by SoftReference will be collected if last time when it was accessed is greater then 10 seconds.

This is very simple in LinQ... You can use the select statement to get an Enumerable of properties of the objects.

var mySkus = myLines.Select(x => x.Sku);

Or if you want it as an Array just do...

var mySkus = myLines.Select(x => x.Sku).ToArray();

You have to specify 0 (meaning false) or 1 (meaning true) as the default. Here is an example:

create table mytable (
     mybool boolean not null default 0
);

FYI: boolean is an alias for tinyint(1).

Here is the proof:

mysql> create table mytable (
    ->          mybool boolean not null default 0
    ->     );
Query OK, 0 rows affected (0.35 sec)

mysql> insert into mytable () values ();
Query OK, 1 row affected (0.00 sec)

mysql> select * from mytable;
+--------+
| mybool |
+--------+
|      0 |
+--------+
1 row in set (0.00 sec)

FYI: My test was done on the following version of MySQL:

mysql> select version();
+----------------+
| version()      |
+----------------+
| 5.0.18-max-log |
+----------------+
1 row in set (0.00 sec)

#include<stdio.h>
int main()
{
    int arr[]={10,20,30,40,50,60};
    int *p;
    int count=0;

    for(p=arr;p<&arr+1;p++)
        count++;

    printf("The no of elements in array=%d",count);

    return 0;
}

OUTPUT=6

EXPLANATION

p is a pointer to a 1-D array, and in the loop for(p=arr,p<&arr+1;p++) I made p point to the base address. Suppose its base address is 1000; if we increment p then it points to 1002 and so on. Now coming to the concept of &arr - It basically represents the whole array, and if we add 1 to the whole array i.e. &arr+1, it gives the address 1012 i.e. the address of next 1-D array (in our case the size of int is 2), so the condition becomes 1000<1012.

So, basically the condition becomes

for(p=1000;p<1012;p++)

And now let's check the condition and count the value

• 1st time p=1000 and p<1012 condition is true: enter in the loop, increment the value of count to 1.
• 2nd time p=1002 and p<1012 condition is true: enter in the loop, increment the value of count to 2.
• ...
• 6th time p=1010 and p<1012 condition is true: enter in the loop, increment the value of count to 6.
• Last time p=1012 and p<1012 condition is false: print the value of count=6 in printf statement.

Embedded C is generally an extension of the C language, they are more or less similar. However, some differences do exist, such as:

• C is generally used for desktop computers, while embedded C is for microcontroller based applications.

• C can use the resources of a desktop PC like memory, OS, etc. While, embedded C has to use with the limited resources, such as RAM, ROM, I/Os on an embedded processor.

• Embedded C includes extra features over C, such as fixed point types, multiple memory areas, and I/O register mapping.

• Compilers for C (ANSI C) typically generate OS dependant executables. Embedded C requires compilers to create files to be downloaded to the microcontrollers/microprocessors where it needs to run.

I prefer doing a "PAD" to the data. MySql calls it LPAD, but you can work your way around to doing the same thing in SQL Server.

ORDER BY  REPLACE(STR(ColName, 3), SPACE(1), '0') 

This formula will provide leading zeroes based on the Column's length of 3. This functionality is very useful in other situations outside of ORDER BY, so that is why I wanted to provide this option.

Results: 1 becomes 001, and 10 becomes 010, while 100 remains the same.

You can use something similar to the below:

if (strlen($str) > 10)
   $str = substr($str, 0, 7) . '...';

Wrap your dialog_custom_layout.xml into RelativeLayout instead of any other layout.That worked for me.

If you want a command-line solution, you can use the ImageMagick convert utility:

convert input.png -transparent red output.png

Ignore this answer. Not that it doesn't work. But there are better methods available. Moreover, Android emphatically discourage direct communication between fragments. See official doc. Thanks user @Wahib Ul Haq for the tip.

Original Answer

Well, you can create a private variable and setter in Fragment B, and set the value from Fragment A itself,

FragmentB.java

private String inputString;
....
....

public void setInputString(String string){
   inputString = string;
}

FragmentA.java

//go to fragment B

FragmentB frag  = new FragmentB();
frag.setInputString(YOUR_STRING);
//create your fragment transaction object, set animation etc
fragTrans.replace(ITS_ARGUMENTS)

Or you can use Activity as you suggested in question..

Use the low-level $.ajax() call:

$.ajax({
  url: "/yourservlet",
  data: { },
  complete: function(xmlHttp) {
    // xmlHttp is a XMLHttpRquest object
    alert(xmlHttp.status);
  }
});

Try this for a redirect:

if (xmlHttp.code != 200) {
  top.location.href = '/some/other/page';
}

There is no max parameter.

Make sure to use the latest npm version while installing packages using npm.

While installing JavaScript, mention the latest version of NodeJS. For example, while installing JavaScript using devtools, use the below code:

devtools i --javascript nodejs:10.15.1

This will download and install the mentioned NodeJS version. Try installing the packages with npm after updating the version. This worked for me.

Simply do:

grouped_df = df.groupby('A')

for key, item in grouped_df:
    print(grouped_df.get_group(key), "\n\n")

This also works,

grouped_df = df.groupby('A')    
gb = grouped_df.groups

for key, values in gb.iteritems():
    print(df.ix[values], "\n\n")

For selective key grouping: Insert the keys you want inside the key_list_from_gb, in following, using gb.keys(): For Example,

gb = grouped_df.groups
gb.keys()

key_list_from_gb = [key1, key2, key3]

for key, values in gb.items():
    if key in key_list_from_gb:
        print(df.ix[values], "\n")

I know this thread is a year old, but the real problem is in your working directory.

I believe that the working directory is C:\Users\Administrator\Documents\Mibot\oops\. Please check for the file named socket.py in this directory. Once you find it, rename or move it. When you import socket, socket.py from the current directory is used instead of the socket.py from Python's directory. Hope this helped. :)

Note: Never use the file names from Python's directory to save your program's file name; it will conflict with your program(s).

In your n++ editor, you can go to Setting > Shortcut mapper and find all shortcut information as well as you can edit them :)

Try this

$(".answer").hide();
$(".coupon_question").click(function() {
    if($(this).is(":checked")) {
        $(".answer").show(300);
    } else {
        $(".answer").hide(200);
    }
});

If you have a staging server that has directory listing enabled, then you can copy the index.html to the production server.

For example:

wget https://staging/dir/index.html

# do any additional processing on index.html

scp index.html prod/dir

I like the Except extension methods, but the original question doesn't have symmetric key access and I prefer Contains (or the Any variation) to join, so with all credit to azuneca's answer:

public static IEnumerable<T> Except<T, TKey>(this IEnumerable<TKey> items,
    IEnumerable<T> other, Func<T, TKey> getKey) {

    return from item in items
        where !other.Contains(getKey(item))
        select item;
}

Which can then be used like:

var filteredApps = unfilteredApps.Except(excludedAppIds, ua => ua.Id);

Also, this version allows for needing a mapping for the exception IEnumerable by using a Select:

var filteredApps = unfilteredApps.Except(excludedApps.Select(a => a.Id), ua => ua.Id);

Add a new user environment variable (Windows 7):

1. Start Menu > Control Panel > System > Advanced System Settings (on the left) > Environment Variables


2. Add a new user variable (at the top) that points your home user directory:

   Variable name: ANDROID_SDK_HOME
   Variable value: a path to a directory of your choice

AVD Manager will use this directory to save its .android directory into it.

For those who may be interested, I blogged about my first foray into Android development...

Alternatively, you can use the Rapid Environment Editor to set the environment variables.

jQuery $.extend(obj1, obj2) would merge 2 objects for you, but you should really be using an array.

var alertsObj = {
    1: {app:'helloworld','message'},
    2: {app:'helloagain',message:'another message'}
};

var alertArr = [
    {app:'helloworld','message'},
    {app:'helloagain',message:'another message'}
];

var newAlert = {app:'new',message:'message'};

$.extend(alertsObj, newAlert);
alertArr.push(newAlert);

This worked for me:

Check the length property and use ? to avoid undefined errors.

So your example would be:

<div class="comeBack_up" *ngIf="previous_info?.length">

UPDATE

The length property only exists on arrays. Since the question was about objects, use Object.getOwnPropertyNames(obj) to get an array of properties from the object. The example becomes:

<div class="comeBack_up" *ngIf="previous_info  && Object.getOwnPropertyNames(previous_info).length > 0">

The previous_info && is added to check if the object exists. If it evaluates to true the next statement checks if the object has at least on proporty. It does not check whether the property has a value.

Try this out. Hope this helps

The gdi32 library is already installed on your computer, few programs will run without it. Your compiler will (if installed properly) normally come with an import library, which is what the linker uses to make a binding between your program and the file in the system. (In the unlikely case that your compiler does not come with import libraries for the system libs, you will need to download the Microsoft Windows Platform SDK.)

To link with gdi32:

This will reliably work with MinGW-gcc for all system libraries (it should work if you use any other compiler too, but I can't talk about things I've not tried). You can also write the library's full name, but writing libgdi32.a has no advantage over gdi32 other than being more type work.
If it does not work for some reason, you may have to provide a different name (for example the library is named gdi32.lib for MSVC).

For libraries in some odd locations or project subfolders, you will need to provide a proper pathname (click on the "..." button for a file select dialog).

You can also manually tag the column with a contrasts attribute, which seems to be respected by the regression functions:

contrasts(df$factorcol) <- contr.treatment(levels(df$factorcol),
   base=which(levels(df$factorcol) == 'RefLevel'))

You might need to be logged in as postgres in order to have full privileges on databases.

su - postgres
psql -l                      # will list all databases on Postgres cluster

pg_dump/pg_restore

  pg_dump -U username -f backup.dump database_name -Fc 

switch -F specify format of backup file:

• c will use custom PostgreSQL format which is compressed and results in smallest backup file size
• d for directory where each file is one table
• t for TAR archive (bigger than custom format)
• -h/--host Specifies the host name of the machine on which the server is running
• -W/--password Force pg_dump to prompt for a password before connecting to a database

restore backup:

   pg_restore -d database_name -U username -C backup.dump

Parameter -C should create database before importing data. If it doesn't work you can always create database eg. with command (as user postgres or other account that has rights to create databases) createdb db_name -O owner

pg_dump/psql

In case that you didn't specify the argument -F default plain text SQL format was used (or with -F p). Then you can't use pg_restore. You can import data with psql.

backup:

pg_dump -U username -f backup.sql database_name

restore:

psql -d database_name -f backup.sql

A coworker just mentioned this thread. I've independently implemented hash tables within bash, and it's not dependent on version 4. From a blog post of mine in March 2010 (before some of the answers here...) entitled Hash tables in bash:

I previously used cksum to hash but have since translated Java's string hashCode to native bash/zsh.

# Here's the hashing function
ht() {
  local h=0 i
  for (( i=0; i < ${#1}; i++ )); do
    let "h=( (h<<5) - h ) + $(printf %d \'${1:$i:1})"
    let "h |= h"
  done
  printf "$h"
}

# Example:

myhash[`ht foo bar`]="a value"
myhash[`ht baz baf`]="b value"

echo ${myhash[`ht baz baf`]} # "b value"
echo ${myhash[@]} # "a value b value" though perhaps reversed
echo ${#myhash[@]} # "2" - there are two values (note, zsh doesn't count right)

It's not bidirectional, and the built-in way is a lot better, but neither should really be used anyway. Bash is for quick one-offs, and such things should quite rarely involve complexity that might require hashes, except perhaps in your ~/.bashrc and friends.

lace to store your loaded class definition and metadata. If a large code-base project is loaded, the insufficient Perm Gen size will cause the popular Java.Lang.OutOfMemoryError: PermGen.

awk 'NF' filename

awk 'NF > 0' filename

sed -i '/^$/d' filename

awk '!/^$/' filename

awk '/./' filename

The NF also removes lines containing only blanks or tabs, the regex /^$/ does not.

With control over the delimiter (Java 8+):

String str = String.join(",", arr);

...or <8:

StringBuilder builder = new StringBuilder();
for(String s : arr) {
    builder.append(s);
}
String str = builder.toString();

Alternatively, if you just want a "debug-style" dump of an array:

String str = Arrays.toString(arr);

And if you're coming from the Android angle:

String str = TextUtils.join(",", arr);

You can modify the above depending on what characters, if any, you want in between strings.

You may see near identical code to the pre-Java 8 code but using StringBuffer - StringBuilder is a newer class that's not thread-safe, but therefore has better performance in a single thread because it does away with unneeded synchronization. In short, you're better using StringBuilder in 99% of cases - functionality wise, the two are identical.

DON'T use a string and just append to it with += like some of the answers show here. This sends the GC through the roof because you're creating and throwing away as many string objects as you have items in your array. For small arrays you might not really notice the difference, but for large ones it can be orders of magnitude slower.

input.next();
String s = input.toString();

change it to

String s = input.next();

May be that's what you were trying to do.

Using LINQ, ofcourse. The below code would give you dictionary of item as string, and the count of each item in your sourc list.

var item2ItemCount = list.GroupBy(item => item).ToDictionary(x=>x.Key,x=>x.Count());

The command yum that you launch was executed properly. It returns a non zero status which means that an error occured during the processing of the command. You probably want to add some argument to your yum command to fix that.

Your code could show this error this way:

import subprocess
try:
    subprocess.check_output("dir /f",shell=True,stderr=subprocess.STDOUT)
except subprocess.CalledProcessError as e:
    raise RuntimeError("command '{}' return with error (code {}): {}".format(e.cmd, e.returncode, e.output))

if (strcmp("hello", "hello") = 0)

Is trying to assign 0 to function return value which isn't lvalue.

Function return values are not lvalue (no storage for it), so any attempt to assign value to something that is not lvalue result in error.

Best practice to avoid such mistakes in if conditions is to use constant value on left side of comparison, so even if you use "=" instead "==", constant being not lvalue will immediately give error and avoid accidental value assignment and causing false positive if condition.

I Would like to add how the pythonic key function works while sorting :

Decorate-Sort-Undecorate Design Pattern :

Python’s support for a key function when sorting is implemented using what is known as the decorate-sort-undecorate design pattern.

It proceeds in 3 steps:

1. Each element of the list is temporarily replaced with a “decorated” version that includes the result of the key function applied to the element.

2. The list is sorted based upon the natural order of the keys.

3. The decorated elements are replaced by the original elements.

Key parameter to specify a function to be called on each list element prior to making comparisons. docs

Here is how I've always done it:

    public static string Serialize(object obj) {
        using(MemoryStream memoryStream = new MemoryStream())
        using(StreamReader reader = new StreamReader(memoryStream)) {
            DataContractSerializer serializer = new DataContractSerializer(obj.GetType());
            serializer.WriteObject(memoryStream, obj);
            memoryStream.Position = 0;
            return reader.ReadToEnd();
        }
    }

    public static object Deserialize(string xml, Type toType) {
        using(Stream stream = new MemoryStream()) {
            byte[] data = System.Text.Encoding.UTF8.GetBytes(xml);
            stream.Write(data, 0, data.Length);
            stream.Position = 0;
            DataContractSerializer deserializer = new DataContractSerializer(toType);
            return deserializer.ReadObject(stream);
        }
    }

Here's a list : http://delphi.about.com/od/devutilities/a/decompiling_3.htm (and this page mentions some more : http://www.program-transformation.org/Transform/DelphiDecompilers )

I've used DeDe on occasion, but it's not really all that powerfull, and it's not up-to-date with current Delphi versions (latest version it supports is Delphi 7 I believe)

Try this code

I find dstat to be quite good. Has to be installed though. Gives you way more information than you need. Netstat will give you packet rates but not bandwith also. netstat -s

Best to import x1 and x2 explicitly:

from file1 import x1, x2

This allows you to avoid unnecessary namespace conflicts with variables and functions from file1 while working in file2.

But if you really want, you can import all the variables:

from file1 import * 

If you are using the 'pylab' for interactive plotting you can set the labelsize at creation time with pylab.ylabel('Example', fontsize=40).

If you use pyplot programmatically you can either set the fontsize on creation with ax.set_ylabel('Example', fontsize=40) or afterwards with ax.yaxis.label.set_size(40).

I try lots of ways and finally try this:

def db_persist(func):
    def persist(*args, **kwargs):
        func(*args, **kwargs)
        try:
            session.commit()
            logger.info("success calling db func: " + func.__name__)
            return True
        except SQLAlchemyError as e:
            logger.error(e.args)
            session.rollback()
            return False

    return persist

and :

@db_persist
def insert_or_update(table_object):
    return session.merge(table_object)

If you have applied border and/or fill on a cell, you need to clear both to go back to the default borders.

You may apply 'None' as the border option and expect the default borders to show, but it will not when the cell fill is white. It's not immediately obvious that it has a white fill, as unfilled cells are also white.

In this case, apply a 'No Fill' on the cells, and you will get the default borders back.

That's it. No messy format painting, no 'Clear Formats', none of those destructive methods. Easy, quick and painless.

I use the following regex that I have tested against all valid UK postcodes. It is based on the recommended rules, but condensed as much as reasonable and does not make use of any special language specific regex rules.

([A-PR-UWYZ]([A-HK-Y][0-9]([0-9]|[ABEHMNPRV-Y])?|[0-9]([0-9]|[A-HJKPSTUW])?) ?[0-9][ABD-HJLNP-UW-Z]{2})

It assumes that the postcode has been converted to uppercase and has not leading or trailing characters, but will accept an optional space between the outcode and incode.

The special "GIR0 0AA" postcode is excluded and will not validate as it's not in the official Post Office list of postcodes and as far as I'm aware will not be used as registered address. Adding it should be trivial as a special case if required.

One possible issue I see is you set your JSON unconventionally within an array/list object. I would recommend using JSON in its most accepted form, i.e.:

test_json = { "a": 1, "b": 2}

Once you do this, adding a json element only involves the following line:

test_json["c"] = 3

This will result in:

{'a': 1, 'b': 2, 'c': 3}

Afterwards, you can add that json back into an array or a list of that is desired.

With right combination of $lookup, $project and $match, you can join mutiple tables on multiple parameters. This is because they can be chained multiple times.

Suppose we want to do following (reference)

SELECT S.* FROM LeftTable S
LEFT JOIN RightTable R ON S.ID =R.ID AND S.MID =R.MID WHERE R.TIM >0 AND 
S.MOB IS NOT NULL

Step 1: Link all tables

you can $lookup as many tables as you want.

$lookup - one for each table in query

$unwind - because data is denormalised correctly, else wrapped in arrays

Python code..

db.LeftTable.aggregate([
                        # connect all tables

                        {"$lookup": {
                          "from": "RightTable",
                          "localField": "ID",
                          "foreignField": "ID",
                          "as": "R"
                        }},
                        {"$unwind": "R"}

                        ])

Step 2: Define all conditionals

$project : define all conditional statements here, plus all the variables you'd like to select.

Python Code..

db.LeftTable.aggregate([
                        # connect all tables

                        {"$lookup": {
                          "from": "RightTable",
                          "localField": "ID",
                          "foreignField": "ID",
                          "as": "R"
                        }},
                        {"$unwind": "R"},

                        # define conditionals + variables

                        {"$project": {
                          "midEq": {"$eq": ["$MID", "$R.MID"]},
                          "ID": 1, "MOB": 1, "MID": 1
                        }}
                        ])

Step 3: Join all the conditionals

$match - join all conditions using OR or AND etc. There can be multiples of these.

$project: undefine all conditionals

Python Code..

db.LeftTable.aggregate([
                        # connect all tables

                        {"$lookup": {
                          "from": "RightTable",
                          "localField": "ID",
                          "foreignField": "ID",
                          "as": "R"
                        }},
                        {"$unwind": "$R"},

                        # define conditionals + variables

                        {"$project": {
                          "midEq": {"$eq": ["$MID", "$R.MID"]},
                          "ID": 1, "MOB": 1, "MID": 1
                        }},

                        # join all conditionals

                        {"$match": {
                          "$and": [
                            {"R.TIM": {"$gt": 0}}, 
                            {"MOB": {"$exists": True}},
                            {"midEq": {"$eq": True}}
                        ]}},

                        # undefine conditionals

                        {"$project": {
                          "midEq": 0
                        }}

                        ])

Pretty much any combination of tables, conditionals and joins can be done in this manner.

If you want an efficient way with milliseconds:

var daysOfYear = [];
for (var d = begin; d <= end; d = d + 86400000) {
    daysOfYear.push(new Date(d));
}

I'm going to assume compiling the QuickFix package does not produce a setup.py file, but rather only compiles the Python bindings and relies on make install to put them in the appropriate place.

In this case, a quick and dirty fix is to compile the QuickFix source, locate the Python extension modules (you indicated on your system these end with a .so extension), and add that directory to your PYTHONPATH environmental variable e.g., add

export PYTHONPATH=~/path/to/python/extensions:PYTHONPATH

or similar line in your shell configuration file.

A more robust solution would include making sure to compile with ./configure --prefix=$HOME/.local. Assuming QuickFix knows to put the Python files in the appropriate site-packages, when you do make install, it should install the files to ~/.local/lib/pythonX.Y/site-packages, which, for Python 2.6+, should already be on your Python path as the per-user site-packages directory.

If, on the other hand, it did provide a setup.py file, simply run

python setup.py install --user

for Python 2.6+.

forward

Control can be forward to resources available within the server from where the call is made. This transfer of control is done by the container internally and browser / client is not involved. This is the major difference between forward and sendRedirect. When the forward is done, the original request and response objects are transfered along with additional parameters if needed.

redirect

Control can be redirect to resources to different servers or domains. This transfer of control task is delegated to the browser by the container. That is, the redirect sends a header back to the browser / client. This header contains the resource url to be redirected by the browser. Then the browser initiates a new request to the given url. Since it is a new request, the old request and response object is lost.

For example, sendRedirect can transfer control from http://google.com to http://anydomain.com but forward cannot do this.

‘session’ is not lost in both forward and redirect.

To feel the difference between forward and sendRedirect visually see the address bar of your browser, in forward, you will not see the forwarded address (since the browser is not involved) in redirect, you can see the redirected address.

To my knowledge there is no difference between NUMERIC and DECIMAL data types. They are synonymous to each other and either one can be used. DECIMAL and NUMERIC data types are numeric data types with fixed precision and scale.

Edit:

Speaking to a few collegues maybe its has something to do with DECIMAL being the ANSI SQL standard and NUMERIC being one Mircosoft prefers as its more commonly found in programming languages. ...Maybe ;)

Here is a basic implementation of writing and then reading json file using json4s.

import org.json4s._
import org.json4s.jackson.JsonMethods._
import org.json4s.JsonDSL._
import java.io._
import scala.io.Source


object MyObject { def main(args: Array[String]) {

  val myMap = Map("a" -> List(3,4), "b" -> List(7,8))

  // writing a file 
  val jsonString = pretty(render(myMap))

  val pw = new PrintWriter(new File("my_json.json"))
  pw.write(jsonString)
  pw.close()

  // reading a file 
  val myString = Source.fromFile("my_json.json").mkString
  println(myString)

  val myJSON = parse(myString)

  println(myJSON)

  // Converting from JOjbect to plain object
  implicit val formats = DefaultFormats
  val myOldMap = myJSON.extract[Map[String, List[Int]]]

  println(myOldMap)
 }
}

Short example in Python:

def comb(sofar, rest, n):
    if n == 0:
        print sofar
    else:
        for i in range(len(rest)):
            comb(sofar + rest[i], rest[i+1:], n-1)

>>> comb("", "abcde", 3)
abc
abd
abe
acd
ace
ade
bcd
bce
bde
cde

For explanation, the recursive method is described with the following example:

Example: A B C D E
All combinations of 3 would be:

• A with all combinations of 2 from the rest (B C D E)
• B with all combinations of 2 from the rest (C D E)
• C with all combinations of 2 from the rest (D E)

JE and JZ are just different names for exactly the same thing: a conditional jump when ZF (the "zero" flag) is equal to 1.

(Similarly, JNE and JNZ are just different names for a conditional jump when ZF is equal to 0.)

You could use them interchangeably, but you should use them depending on what you are doing:

• JZ/JNZ are more appropriate when you are explicitly testing for something being equal to zero:

  dec  ecx
  jz   counter_is_now_zero
  

• JE and JNE are more appropriate after a CMP instruction:

  cmp  edx, 42
  je   the_answer_is_42
  

  (A CMP instruction performs a subtraction, and throws the value of the result away, while keeping the flags; which is why you get ZF=1 when the operands are equal and ZF=0 when they're not.)

First - most classes will never need to be thread-safe. Use YAGNI: only apply thread-safety when you know you actually are going to use it (and test it).

For the method-level stuff, there is [MethodImpl]:

[MethodImpl(MethodImplOptions.Synchronized)]
public void SomeMethod() {/* code */}

This can also be used on accessors (properties and events):

private int i;
public int SomeProperty
{
    [MethodImpl(MethodImplOptions.Synchronized)]
    get { return i; }
    [MethodImpl(MethodImplOptions.Synchronized)]
    set { i = value; }
}

Note that field-like events are synchronized by default, while auto-implemented properties are not:

public int SomeProperty {get;set;} // not synchronized
public event EventHandler SomeEvent; // synchronized

Personally, I don't like the implementation of MethodImpl as it locks this or typeof(Foo) - which is against best practice. The preferred option is to use your own locks:

private readonly object syncLock = new object();
public void SomeMethod() {
    lock(syncLock) { /* code */ }
}

Note that for field-like events, the locking implementation is dependent on the compiler; in older Microsoft compilers it is a lock(this) / lock(Type) - however, in more recent compilers it uses Interlocked updates - so thread-safe without the nasty parts.

This allows more granular usage, and allows use of Monitor.Wait/Monitor.Pulse etc to communicate between threads.

Past : from sklearn.cross_validation (This package is deprecated in 0.18 version from 0.20 onwards it is changed to from sklearn import model_selection).

Present: from sklearn import model_selection

Example 2:

Past : from sklearn.cross_validation import cross_val_score (Version 0.18 which is deprecated)

Present : from sklearn.model_selection import cross_val_score

I assume you mean struct and not strict, but on a 32-bit system it'll be either 5 or 8 bytes, depending on if the compiler is padding the struct.

https://docs.microsoft.com/en-us/sql/t-sql/data-types/ntext-text-and-image-transact-sql

image

Variable-length binary data from 0 through 2^31-1 (2,147,483,647) bytes. Still it IS supported to use image datatype, but be aware of:

https://docs.microsoft.com/en-us/sql/t-sql/data-types/binary-and-varbinary-transact-sql

varbinary [ ( n | max) ]

Variable-length binary data. n can be a value from 1 through 8,000. max indicates that the maximum storage size is 2^31-1 bytes. The storage size is the actual length of the data entered + 2 bytes. The data that is entered can be 0 bytes in length. The ANSI SQL synonym for varbinary is binary varying.

So both are equally in size (2GB). But be aware of:

https://docs.microsoft.com/en-us/sql/database-engine/deprecated-database-engine-features-in-sql-server-2016#features-not-supported-in-a-future-version-of-sql-server

Though the end of "image" datatype is still not determined, you should use the "future" proof equivalent.

But you have to ask yourself: why storing BLOBS in a Column?

In version 0.2.13, You should be able to pass objects into $state.go,

$state.go('myState', {myParam: {some: 'thing'}})

$stateProvider.state('myState', {
                url: '/myState/{myParam:json}',
                params: {myParam: null}, ...

and then access the parameter in your controller.

$stateParams.myParam //should be {some: 'thing'}

myParam will not show up in the URL.

Source:

See the comment by christopherthielen https://github.com/angular-ui/ui-router/issues/983, reproduced here for convenience:

christopherthielen: Yes, this should be working now in 0.2.13.

.state('foo', { url: '/foo/:param1?param2', params: { param3: null } // null is the default value });

$state.go('foo', { param1: 'bar', param2: 'baz', param3: { id: 35, name: 'what' } });

$stateParams in 'foo' is now { param1: 'bar', param2: 'baz', param3: { id: 35, name: 'what' } }

url is /foo/bar?param2=baz.

Maybe I'm missing something here... but if you want the present working directory you can just use this: (Get-Location).Path for a string, or Get-Location for an object.

Unless you're referring to something like this, which I understand after reading the question again.

function Get-Script-Directory
{
    $scriptInvocation = (Get-Variable MyInvocation -Scope 1).Value
    return Split-Path $scriptInvocation.MyCommand.Path
}

The state of the checkbox will be reflected on whatever model you have it bound to, in this case, $scope.answers[item.questID]

To change specifically C# (OmniSharp) formatting settings you can use a json file:
User: ~/.omnisharp/omnisharp.json or %USERPROFILE%\.omnisharp\omnisharp.json
Workspace: omnisharp.json file in the working directory which OmniSharp has been pointed at.

Example:

{
  "FormattingOptions": {
    "NewLinesForBracesInMethods": false,
    "NewLinesForBracesInProperties": false,
    "NewLinesForBracesInAccessors": false,
    "NewLinesForBracesInAnonymousMethods": false,
    "NewLinesForBracesInControlBlocks": false,
    "NewLinesForBracesInObjectCollectionArrayInitializers": false,
    "NewLinesForBracesInLambdaExpressionBody": false
  }
}

Details on this post | omnisharp.json schema (it's already in vscode, you can just CTRL+SPACE it)

Other language extensions may have similar files for setting it.

If someone uses AndroidStudio make sure that the assets folder is placed in

1. app/src/main/assets

   directory.

WebDriverWait wait = new WebDriverWait(driver,5)
wait.until(ExpectedConditions.visibilityOf(element));

you can use this as some time before loading whole page code gets executed and throws and error. time is in second

The maximum values do not depend on Eclipse, it depends on your OS (and obviously on the physical memory available).
