In python 3.x all strings are sequences of Unicode characters. and doing the isinstance check for str (which means unicode string by default) should suffice.

isinstance(x, str)

With regards to python 2.x, Most people seem to be using an if statement that has two checks. one for str and one for unicode.

If you want to check if you have a 'string-like' object all with one statement though, you can do the following:

isinstance(x, basestring)

Solution:

sort -k 2 -n filename

more verbosely written as:

sort --key 2 --numeric-sort filename

Example:

$ cat filename
A 12
B 48
C 3

$ sort --key 2 --numeric-sort filename 
C 3
A 12
B 48

Explanation:

• -k # - this argument specifies the first column that will be used to sort. (note that column here is defined as a whitespace delimited field; the argument -k5 will sort starting with the fifth field in each line, not the fifth character in each line)

• -n - this option specifies a "numeric sort" meaning that column should be interpreted as a row of numbers, instead of text.

More:

Other common options include:

• -r - this option reverses the sorting order. It can also be written as --reverse.
• -i - This option ignores non-printable characters. It can also be written as --ignore-nonprinting.
• -b - This option ignores leading blank spaces, which is handy as white spaces are used to determine the number of rows. It can also be written as --ignore-leading-blanks.
• -f - This option ignores letter case. "A"=="a". It can also be written as --ignore-case.
• -t [new separator] - This option makes the preprocessing use a operator other than space. It can also be written as --field-separator.

There are other options, but these are the most common and helpful ones, that I use often.

Following is a list of solutions to centering things in CSS horizontally. The snippet includes all of them.

display: flex

.container {
  display: flex;
  justify-content: center;
}

Notes:

• It’s not a hack
• Browser support: flexbox

max-width & margin

You can horizontally center a block-level element by assigning a fixed width and setting margin-right and margin-left to auto.

.container ul {
  /* for IE below version 7 use `width` instead of `max-width` */
  max-width: 800px;
  margin-right: auto;
  margin-left: auto;
}

Notes:

• No container needed
• Requires (maximum) width of the centered element to be known

IE9+: transform: translatex(-50%) & left: 50%

This is similar to the quirky centering method which uses absolute positioning and negative margins.

.container {
  position: relative;
}

.container ul {
  position: absolute;
  left: 50%;
  transform: translatex(-50%);
}

Notes:

• The centered element will be removed from document flow. All elements will completely ignore of the centered element.
• This technique allows vertical centering by using top instead of left and translateY() instead of translateX(). The two can even be combined.
• Browser support: transform2d

IE8+: display: table & margin

Just like the first solution, you use auto values for right and left margins, but don’t assign a width. If you don’t need to support IE7 and below, this is better suited, although it feels kind of hacky to use the table property value for display.

.container ul {
  display: table;
  margin-right: auto;
  margin-left: auto;
}

IE8+: display: inline-block & text-align

Centering an element just like you would do with regular text is possible as well. Downside: You need to assign values to both a container and the element itself.

.container {
  text-align: center;
}

.container ul {
  display: inline-block;

  /* One most likely needs to realign flow content */
  text-align: initial;
}

Notes:

• Does not require to specify a (maximum) width
• Aligns flow content to the center (potentially unwanted side effect)
• Works kind of well with a dynamic number of menu items (i.e. in cases where you can’t know the width a single item will take up)

I seem to remember that Internet Explorer gets confused if the accept-charset encoding doesn't match the encoding specified in the content-type header. In your example, you claim the document is sent as UTF-8, but want form submits in ISO-8859-1. Try matching those and see if that solves your problem.

A workaround, if you want it to be absolutely silent, is to redirect the output to a file (and optionally delete it later).

Robocopy src dest > output.log
del output.log

-> Simply ADD [RequireHttps] on top of the public class HomeController : Controller.

-> And add GlobalFilters.Filters.Add(new RequireHttpsAttribute()); in 'protected void Application_Start()' method in Global.asax.cs file.

Which forces your entire application to HTTPS.

That's no struts related problem but rather plain HMTL/CSS.

I'm not HTML or CSS expert, but I guess you could use a div with a border on the left or right side only.

Just throw everything you read into a MemoryStream and get the byte array in the end. As noted, you should be reading from the underlying stream to get the raw bytes.

var bytes = default(byte[]);
using (var memstream = new MemoryStream())
{
    var buffer = new byte[512];
    var bytesRead = default(int);
    while ((bytesRead = reader.BaseStream.Read(buffer, 0, buffer.Length)) > 0)
        memstream.Write(buffer, 0, bytesRead);
    bytes = memstream.ToArray();
}

Or if you don't want to manage the buffers:

var bytes = default(byte[]);
using (var memstream = new MemoryStream())
{
    reader.BaseStream.CopyTo(memstream);
    bytes = memstream.ToArray();
}

char *p = "String";   means pointer to a string type variable.

char p3[5] = "String"; means you are pre-defining the size of the array to consist of no more than 5 elements. Note that,for strings the null "\0" is also considered as an element.So,this statement would give an error since the number of elements is 7 so it should be:

char p3[7]= "String";

You can refer below example for getting a comma separated string array from list.

Example:

List<string> testList= new List<string>();
testList.Add("Apple"); // Add string 1
testList.Add("Banana"); // 2
testList.Add("Mango"); // 3
testList.Add("Blue Berry"); // 4
testList.Add("Water Melon"); // 5

string JoinDataString = string.Join(",", testList.ToArray());

You can do this with merge:

df_merged = df1.merge(df2, how='outer', left_index=True, right_index=True)

The keyword argument how='outer' keeps all indices from both frames, filling in missing indices with NaN. The left_index and right_index keyword arguments have the merge be done on the indices. If you get all NaN in a column after doing a merge, another troubleshooting step is to verify that your indices have the same dtypes.

The merge code above produces the following output for me:

                V1    V2
A 2012-01-01  12.0  15.0
  2012-02-01  14.0   NaN
  2012-03-01   NaN  21.0
B 2012-01-01  15.0  24.0
  2012-02-01   8.0   9.0
C 2012-01-01  17.0   NaN
  2012-02-01   9.0   NaN
D 2012-01-01   NaN   7.0
  2012-02-01   NaN  16.0

This is a press down button example I've made:

<div>
    <form id="forminput" action="action" method="POST">
       ...
    </form>
    <div style="right: 0px;bottom: 0px;position: fixed;" class="thumbnail">
        <div class="image">
            <a onclick="document.getElementById('forminput').submit();">
                <img src="images/button.png" alt="Some awesome text">
            </a>
        </div>
    </div>
</div>

the CSS file:

.thumbnail {
    width: 128px;
    height: 128px;
}

.image {
    width: 100%;
    height: 100%;    
}

.image img {
    -webkit-transition: all .25s ease; /* Safari and Chrome */
    -moz-transition: all .25s ease; /* Firefox */
    -ms-transition: all .25s ease; /* IE 9 */
    -o-transition: all .25s ease; /* Opera */
    transition: all .25s ease;
    max-width: 100%;
    max-height: 100%;
}

.image:hover img {
    -webkit-transform:scale(1.05); /* Safari and Chrome */
    -moz-transform:scale(1.05); /* Firefox */
    -ms-transform:scale(1.05); /* IE 9 */
    -o-transform:scale(1.05); /* Opera */
     transform:scale(1.05);
}

.image:active img {
    -webkit-transform:scale(.95); /* Safari and Chrome */
    -moz-transform:scale(.95); /* Firefox */
    -ms-transform:scale(.95); /* IE 9 */
    -o-transform:scale(.95); /* Opera */
     transform:scale(.95);
}

Enjoy it!

You are thinking in the right direction. Merge master with mobiledevicesupport continuously and merge mobiledevicesupport with master when mobiledevicesupport is stable. Each developer will have his own branch and can merge to and from either on master or mobiledevicesupport depending on their role.

When one has to scroll down a gridview to select a row, MaintainScrollPositionOnPostBack="true" will make it continue to show that row after one has selected it.

A solution is:

public void javascriptclick(String element)
{
    WebElement webElement = driver.findElement(By.xpath(element));
    JavascriptExecutor js = (JavascriptExecutor) driver;

    js.executeScript("arguments[0].click();", webElement);
    System.out.println("javascriptclick" + " " + element);
}

From answer that was removed due to being written in Spanish:

All of the above fixes may not work in android studio. If you are using ANDROID STUDIO please use the following fix.

Use

xmlns: compat = "http://schemas.android.com/tools"

on the menu label instead of

xmlns: compat = "http://schemas.android.com/apk/res-auto"

Make sure your routing.yml file has 'id' specified in it. In other words, it should look like:

_category:
    path: /category/{id}

There is of course some apache log files. Search in your apache configuration files for 'Log' keyword, you'll certainly find plenty of them. Depending on your OS and installation places may vary (in a Typical Linux server it would be /var/log/apache2/[access|error].log).

Having a 503 error in Apache usually means the proxied page/service is not available. I assume you're using tomcat and that means tomcat is either not responding to apache (timeout?) or not even available (down? crashed?). So chances are that it's a configuration error in the way to connect apache and tomcat or an application inside tomcat that is not even sending a response for apache.

Sometimes, in production servers, it can as well be that you get too much traffic for the tomcat server, apache handle more request than the proxyied service (tomcat) can accept so the backend became unavailable.

Vanilla Javascript:

this.querySelector(':checked').getAttribute('data-id')

After submitting the post you can redirect using inline javascript like below:

echo '<script language="javascript">window.location.href=""</script>';              

I use this code all the time to clear form data and reload the current form. The empty href reloads the current page in a reset mode.

For Spark 1.5 or later, you can use the functions package:

from pyspark.sql.functions import *
newDf = df.withColumn('address', regexp_replace('address', 'lane', 'ln'))

Quick explanation:

• The function withColumn is called to add (or replace, if the name exists) a column to the data frame.
• The function regexp_replace will generate a new column by replacing all substrings that match the pattern.

In C#, a base class' constructor runs before the derived class' constructor, so any instance fields that a derived class might use in the possibly-overridden virtual member are not initialized yet.

Do note that this is just a warning to make you pay attention and make sure it's all-right. There are actual use-cases for this scenario, you just have to document the behavior of the virtual member that it can not use any instance fields declared in a derived class below where the constructor calling it is.

Using double to store large integers is dubious; the largest integer that can be stored reliably in double is much smaller than DBL_MAX. You should use long long, and if that's not enough, you need your own arbitrary-precision code or an existing library.

Just change

var div = '<div>top div</div>'; // you just created a text string

to

var div = document.createElement("div"); // we want a DIV element instead
div.innerHTML = "top div";

<option value="" defaultValue disabled> Something </option>

you can replace defaultValue with selected but that would give warning.

If anything else doesn't help you. And maybe earlier you installed apache2 with info.php test file. Just clear App Data (cache,cookie) for localhost.

You can use actual html tags <xmp> and </xmp> to output the string as is to show all of the tags in between the xmp tags.

Or you can also use on the server Server.UrlEncode or HttpUtility.HtmlEncode.

Yes, it means "not equal", either less than or greater than. e.g

If x <> y Then

can be read as

if x is less than y or x is greater than y then

The logical outcome being "If x is anything except equal to y"

Let me clarify two points here :

• Firstly non-default argument should not follow the default argument, it means you can't define (a = 'b',c) in function. The correct order of defining parameter in function are :
• positional parameter or non-default parameter i.e (a,b,c)
• keyword parameter or default parameter i.e (a = 'b',r= 'j')
• keyword-only parameter i.e (*args)
• var-keyword parameter i.e (**kwargs)

def example(a, b, c=None, r="w" , d=[], *ae, **ab):

(a,b) are positional parameter

(c=none) is optional parameter

(r="w") is keyword parameter

(d=[]) is list parameter

(*ae) is keyword-only

(*ab) is var-keyword parameter

so first re-arrange your parameters

• now the second thing is you have to define len1 when you are doing hgt=len1 the len1 argument is not defined when default values are saved, Python computes and saves default values when you define the function len1 is not defined, does not exist when this happens (it exists only when the function is executed)

so second remove this "len1 = hgt" it's not allowed in python.

keep in mind the difference between argument and parameters.

The following should work:

from matplotlib import pyplot as plt
plt.imshow(data, interpolation='nearest')
plt.show()

If you are using Jupyter notebook/lab, use this inline command before importing matplotlib:

%matplotlib inline 

To adjust the length of the samples:

set key samplen X

(default is 4)

To adjust the vertical spacing of the samples:

set key spacing X

(default is 1.25)

and (for completeness), to adjust the fontsize:

set key font "<face>,<size>"

(default depends on the terminal)

And of course, all these can be combined into one line:

set key samplen 2 spacing .5 font ",8"

Note that you can also change the position of the key using set key at <position> or any one of the pre-defined positions (which I'll just defer to help key at this point)

You are using an old version of the date picker js. Upgrade datepicker js with latest one.

Replace your bootstrap-datetimepicker.min.js file with this will work..

<script src="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-datetimepicker/3.1.3/js/bootstrap-datetimepicker.min.js"></script>

The answer is super simple, the type is Date:

const d: Date = new Date(); // but the type can also be inferred from "new Date()" already

It is the same as with every other object instance :)

If you have a very complex class with a lot of options of which only some combinations are valid, consider using a Builder. Works very well both codewise but also logically.

The Builder is a nested class with methods only designed to set fields, and then the ComplexClass constructor only takes such a Builder as an argument.

Edit: The ComplexClass constructor can ensure that the state in the Builder is valid. This is very hard to do if you just use setters on ComplexClass.

To set your ImageView equal to half the screen, you need to add the following to your XML for the ImageView:

<ImageView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_centerInParent="true"
    android:scaleType="fitXY"
    android:adjustViewBounds="true"/>

To then set the height equal to this width, you need to do it in code. In the getView method of your GridView adapter, set the ImageView height equal to its measured width:

mImageView.getLayoutParams().height = mImageView.getMeasuredWidth();

I realize this question is a bit old but here's a really simple solution that was missing. You don't need to create a custom ListView or even a custom layout.

Just create an anonymous subclass of ArrayAdapter and override getView(). Let super.getView() handle all the heavy lifting. Since simple_list_item_1 is just a text view you can customize it (e.g. set textColor) and then return it.

Here's an example from one of my apps. I'm displaying a list of recent locations and I want all occurrences of "Current Location" to be blue and the rest white.

ListView listView = (ListView) this.findViewById(R.id.listView);
listView.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, MobileMuni.getBookmarkStore().getRecentLocations()) {
    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        TextView textView = (TextView) super.getView(position, convertView, parent);

        String currentLocation = RouteFinderBookmarksActivity.this.getResources().getString(R.string.Current_Location);
        int textColor = textView.getText().toString().equals(currentLocation) ? R.color.holo_blue : R.color.text_color_btn_holo_dark;
        textView.setTextColor(RouteFinderBookmarksActivity.this.getResources().getColor(textColor));

        return textView;
    }
});

I also solved my problem with Mosh's answer and I thought PeterB's answer was a bit of since it used an enum as foreign key. Remember that you will need to add a new migration after adding this code.

I can also recommend this blog post for other solutions:

http://www.kianryan.co.uk/2013/03/orphaned-child/

Code:

public class Child
{
    [Key, Column(Order = 0), DatabaseGenerated(DatabaseGeneratedOption.Identity)]
    public int Id { get; set; }

    public string Heading { get; set; }
    //Add other properties here.

    [Key, Column(Order = 1)]
    public int ParentId { get; set; }

    public virtual Parent Parent { get; set; }
}

Just write a method for changing imageview

public void setImage(final Context mContext, final ImageView imageView, int picture)
{
    if (mContext != null && imageView != null)
    {
        try
        {
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP)
            {
                imageView.setImageDrawable(mContext.getResources().getDrawable(picture, mContext.getApplicationContext().getTheme()));
            } else
            {
                imageView.setImageDrawable(mContext.getResources().getDrawable(picture));
            }
        } catch (Exception e)
        {
            e.printStackTrace();
        }
    }
}

unset is a function, not an operator. Use it like unset($_SESSION['key']); to unset that session key. You can, however, use session_destroy(); as well. (Make sure to start the session with session_start(); as well)

Well, yes, and no...

I understand that you want your local copies to "override" what's in the remote, but, oh, man, if someone has modified the files in the remote repo in some different way, and you just ignore their changes and try to "force" your own changes without even looking at possible conflicts, well, I weep for you (and your coworkers) ;-)

That said, though, it's really easy to do the "right thing..."

Step 1:

git stash

in your local repo. That will save away your local updates into the stash, then revert your modified files back to their pre-edit state.

Step 2:

git pull

to get any modified versions. Now, hopefully, that won't get any new versions of the files you're worried about. If it doesn't, then the next step will work smoothly. If it does, then you've got some work to do, and you'll be glad you did.

Step 3:

git stash pop

That will merge your modified versions that you stashed away in Step 1 with the versions you just pulled in Step 2. If everything goes smoothly, then you'll be all set!

If, on the other hand, there were real conflicts between what you pulled in Step 2 and your modifications (due to someone else editing in the interim), you'll find out and be told to resolve them. Do it.

Things will work out much better this way - it will probably keep your changes without any real work on your part, while alerting you to serious, serious issues.

for (int i = 0; i < 8; i++)

It's a for loop, which will execute the next statement a number of times, depending on the conditions inside the parenthesis.

for (int i = 0; i < 8; i++)

Start by setting i = 0

for (int i = 0; i < 8; i++)

Continue looping while i < 8.

for (int i = 0; i < 8; i++)

Every time you've been around the loop, increase i by 1.

For example;

for (int i = 0; i < 8; i++)
    do(i);

will call do(0), do(1), ... do(7) in order, and stop when i reaches 8 (ie i < 8 is false)

If you are reaching the mac connection limit go to /etc/my.cnf and under the [mysqld] section add max_connections = 500

and restart MySQL.

One possible issue is that your new class has a different Target or different Targets from the other one.

For example, it might have a testing target while the other one doesn't. For this specific case, you have to include all of your classes in the testing target or none of them.

Here is a tidyverse option that might work depending on the data, and some caveats on its usage:

library(tidyverse)

starting_df %>% 
  rownames_to_column() %>% 
  gather(variable, value, -rowname) %>% 
  spread(rowname, value)

rownames_to_column() is necessary if the original dataframe has meaningful row names, otherwise the new column names in the new transposed dataframe will be integers corresponding to the orignal row number. If there are no meaningful row names you can skip rownames_to_column() and replace rowname with the name of the first column in the dataframe, assuming those values are unique and meaningful. Using the tidyr::smiths sample data would be:

smiths %>% 
    gather(variable, value, -subject) %>% 
    spread(subject, value)

Using the example starting_df with the tidyverse approach will throw a warning message about dropping attributes. This is related to converting columns with different attribute types into a single character column. The smiths data will not give that warning because all columns except for subject are doubles.

The earlier answer using as.data.frame(t()) will convert everything to a factor if there are mixed column types unless stringsAsFactors = FALSE is added, whereas the tidyverse option converts everything to a character by default if there are mixed column types.

No. Every DOM element, if it has an id, has a single, unique id. You could approximate it using something like:

<div id='enclosing_id_123'><span id='enclosed_id_123'></span></div>

and then use navigation to get what you really want.

If you are just looking to apply styles, class names are better.

The easiest way to do it, that I have found.. Apply the System.Xml.Serialization.XmlArray attribute to it.

[System.Xml.Serialization.XmlArray] //This is the part that makes it work
List<object> serializableList = new List<object>();

XmlSerializer xmlSerializer = new XmlSerializer(serializableList.GetType());

serializableList.Add(PersonList);

using (StreamWriter streamWriter = System.IO.File.CreateText(fileName))
{
    xmlSerializer.Serialize(streamWriter, serializableList);
}

The serializer will pick up on it being an array and serialize the list's items as child nodes.

You need to add else in your lambda function. Because you are telling what to do in case your condition(here x < 90) is met, but you are not telling what to do in case the condition is not met.

sample['PR'] = sample['PR'].apply(lambda x: 'NaN' if x < 90 else x) 

From your description, what you probably want is os.Readdirnames.

func (f *File) Readdirnames(n int) (names []string, err error)

Readdirnames reads the contents of the directory associated with file and returns a slice of up to n names of files in the directory, in directory order. Subsequent calls on the same file will yield further names.

...

If n <= 0, Readdirnames returns all the names from the directory in a single slice.

Snippet:

file, err := os.Open(path)
if err != nil {
    return err
}
defer file.Close()
names, err := file.Readdirnames(0)
if err != nil {
    return err
}
fmt.Println(names)

You can add button in toolbar

<android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        app:popupTheme="@style/AppTheme.PopupOverlay"
        app:title="title">

        <Button
            android:id="@+id/button"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="right"
            android:layout_marginRight="16dp"
            android:background="@color/transparent"
            android:drawableRight="@drawable/ic_your_icon"
            android:drawableTint="@drawable/btn_selector"
            android:text="@string/sort_by_credit"
            android:textColor="@drawable/btn_selector"
            />

    </android.support.v7.widget.Toolbar>

create file btn_selector.xml in drawable

<?xml version="1.0" encoding="utf-8" ?>

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

<item
    android:state_selected="true"
    android:color="@color/white"
    />
<item
    android:color="@color/white_30_opacity"
    />

java:

private boolean isSelect = false;

OnClickListener for button:

private void myClick() {
    if (!isSelect) {
       //**your code**//
        isSelect = true;
    } else {//**your code**//
        isSelect = false;
    }
    sort.setSelected(isSelect);
}

the problem might be that networkservice has no read rights

salution:

rightclick your upload folder -> poperty's -> security ->Edit -> add -> type :NETWORK SERVICE -> check box full control allow-> press ok or apply

also you can open more than two page try this

`<a href="http://www.microsoft.com" target="_blank" onclick="window.open('http://www.google.com'); window.open('http://www.yahoo.com');">Click Here</a>`

You can also do it like:

str = str.replace(/\s/g, "+");

Have a look at this fiddle.

Right click folder -> Click Tortoise SVN -> Check for modification

This is not explicitly mentioned, but based on the following docs, I think it is implied that an app needs to declare and implement a BackupAgent in order for data backup to work, even in the case when allowBackup is set to true (which is the default value).

http://developer.android.com/reference/android/R.attr.html#allowBackup http://developer.android.com/reference/android/app/backup/BackupManager.html http://developer.android.com/guide/topics/data/backup.html

#For brevity, I didn't define a function.

#Place the directories you want to exclude in this array.
#Case insensitive and exact match. So 'archive' and
#'ArcHive' will match but 'BuildArchive' will not.
$noDirs = @('archive')

#Build a regex using array of excludes
$excRgx = '^{0}$' -f ($noDirs -join ('$|^'))

#Rather than use the gci -Recurse option, use a more
#performant approach by not processing the match(s) as
#soon as they are located.
$cmd = {
  Param([string]$Path)
  Get-ChildItem $Path -Directory |
  ForEach-Object {
    if ($_.Name -inotmatch $excRgx) {
      #Recurse back into the scriptblock
      Invoke-Command $cmd -ArgumentList $_.FullName;
      #If you want all directory info change to return $_
      return $_.FullName
    }
  }
}

#In this example, start with the current directory
$searchPath = .
#Start the Recursion
Invoke-Command $cmd -ArgumentList $searchPath

in regard of answer from @Perception, its true to be very memory-consuming when working with byte arrays, but you could also simply write back into the outputstream

@Path("/picture")
public class ProfilePicture {
  @GET
  @Path("/thumbnail")
  @Produces("image/png")
  public StreamingOutput getThumbNail() {
    return new StreamingOutput() {
      @Override
      public void write(OutputStream os) throws IOException, WebApplicationException {
        //... read your stream and write into os
      }
    };
  }
}

Using jQuery you can use contents(). For example:

var inside = $('#one').contents();

Explaining if any one want to send some parameters while calling stored procedure as below,

using (SqlConnection con = new SqlConnection(connetionString))
            {
                using (var command = new SqlCommand(storedProcName, con))
                {
                    foreach (var item in sqlParams)
                    {
                        item.Direction = ParameterDirection.Input;
                        item.DbType = DbType.String;
                        command.Parameters.Add(item);
                    }
                    command.CommandType = CommandType.StoredProcedure;
                    using (var adapter = new SqlDataAdapter(command))
                    {
                        adapter.Fill(dt);
                    }
                }
            }

To remove any whitespaces you could use:

myValue := replace(replace(replace(replace(replace(replace(myValue, chr(32)), chr(9)),  chr(10)), chr(11)), chr(12)), chr(13));

Example: remove all whitespaces in a table:

update myTable t
    set t.myValue = replace(replace(replace(replace(replace(replace(t.myValue, chr(32)), chr(9)), chr(10)), chr(11)), chr(12)), chr(13))
where
    length(t.myValue) > length(replace(replace(replace(replace(replace(replace(t.myValue, chr(32)), chr(9)), chr(10)), chr(11)), chr(12)), chr(13)));

or

update myTable t
    set t.myValue = replace(replace(replace(replace(replace(replace(t.myValue, chr(32)), chr(9)), chr(10)), chr(11)), chr(12)), chr(13))
where
    t.myValue like '% %'

Add "display:block;" in your .btn-pTool class

If you care about proper rounding up then:

function roundNumericStrings(str , numOfDecPlacesRequired){ 
     var roundFactor = Math.pow(10, numOfDecPlacesRequired);  
     return (Math.round(parseFloat(str)*roundFactor)/roundFactor).toString();  }

Else if you don't then you already have a reply from previous posts

str.slice(0, -1)

The identity section goes under the system.web section, not under authentication:

<system.web>
  <authentication mode="Windows"/>
  <identity impersonate="true" userName="foo" password="bar"/>
</system.web>

System.Drawing.Color myColor = System.Drawing.ColorTranslator.FromHtml("Red");

(Use my method if you want to accept HTML-style hex colors.)

In SQL Server 2017 & later, use Trim

Select Trim(char(10) + char(13) from @str)

1. it trims on starting and ending, not in the middle
2. the order of \r and \n does not matter

I use it to trim special characters for a file name

Select Trim(char(10) + char(13) + ' *<>' from @fileName)

AtomicReference is also a solution to pass the error to the main thread .Is same approach like the one of Dan Cruz .

AtomicReference<Throwable> errorReference = new AtomicReference<>();

    Thread thread = new Thread() {
        public void run() {
            throw new RuntimeException("TEST EXCEPTION");

        }
    };
    thread.setUncaughtExceptionHandler((th, ex) -> {
        errorReference.set(ex);
    });
    thread.start();
    thread.join();
    Throwable newThreadError= errorReference.get();
    if (newThreadError!= null) {
        throw newThreadError;
    }  

The only change is that instead of creating a volatile variable you can use AtomicReference which did same thing behind the scenes.

How about get_the_category?

You can then do

$category = get_the_category();
$firstCategory = $category[0]->cat_name;

You have two easy ways to do this. Jay has covered the accurate way of checking from the center of the ball.

The easier way is to use a rectangle bounding box, set the size of your box to be 80% the size of the ball, and you'll simulate collision pretty well.

Add a method to your ball class:

public Rectangle getBoundingRect()
{
   int ballHeight = (int)Ball.Height * 0.80f;
   int ballWidth = (int)Ball.Width * 0.80f;
   int x = Ball.X - ballWidth / 2;
   int y = Ball.Y - ballHeight / 2;

   return new Rectangle(x,y,ballHeight,ballWidth);
}

Then, in your loop:

// Checks every ball against every other ball. 
// For best results, split it into quadrants like Ryan suggested. 
// I didn't do that for simplicity here.
for (int i = 0; i < balls.count; i++)
{
    Rectangle r1 = balls[i].getBoundingRect();

    for (int k = 0; k < balls.count; k++)
    {

        if (balls[i] != balls[k])
        {
            Rectangle r2 = balls[k].getBoundingRect();

            if (r1.Intersects(r2))
            {
                 // balls[i] collided with balls[k]
            }
        }
    }
}

For recent SQL:

select * from v$sql

For history:

select * from dba_hist_sqltext

read about the lists() method

$test=test::select('id')->where('id' ,'>' ,0)->lists('id')->toArray()

Just to expand a little on Dirk's example:

It helps to think of a data frame as a list with equal length vectors. That's probably why names works with a data frame but not a matrix.

The other useful function is dimnames which returns the names for every dimension. You will notice that the rownames function actually just returns the first element from dimnames.

Regarding rownames and row.names: I can't tell the difference, although rownames uses dimnames while row.names was written outside of R. They both also seem to work with higher dimensional arrays:

>a <- array(1:5, 1:4)
> a[1,,,]
> rownames(a) <- "a"
> row.names(a)
[1] "a"
> a
, , 1, 1    
  [,1] [,2]
a    1    2

> dimnames(a)
[[1]]
[1] "a"

[[2]]
NULL

[[3]]
NULL

[[4]]
NULL

I see a lot of complicated answers, while this is super simple in Bootstrap 3:

Step 1: Use the official example code to create your radio button group, and give the container an id:

<div id="myButtons" class="btn-group" data-toggle="buttons">
  <label class="btn btn-primary active">
    <input type="radio" name="options" id="option1" autocomplete="off" checked> Radio 1 (preselected)
  </label>
  <label class="btn btn-primary">
    <input type="radio" name="options" id="option2" autocomplete="off"> Radio 2
  </label>
  <label class="btn btn-primary">
    <input type="radio" name="options" id="option3" autocomplete="off"> Radio 3
  </label>
</div>

Step 2: Use this jQuery handler:

$("#myButtons :input").change(function() {
    console.log(this); // points to the clicked input button
});

Try the fiddle demo

Just for completion sake, I would like to add that you indeed can create an operator ostream& operator << (ostream& os) inside a class and it can work. From what I know it's not a good idea to use it, because it's very convoluted and unintuitive.

Let's assume we have this code:

#include <iostream>
#include <string>

using namespace std;

struct Widget
{
    string name;

    Widget(string _name) : name(_name) {}

    ostream& operator << (ostream& os)
    {
        return os << name;
    }
};

int main()
{
    Widget w1("w1");
    Widget w2("w2");

    // These two won't work
    {
        // Error: operand types are std::ostream << std::ostream
        // cout << w1.operator<<(cout) << '\n';

        // Error: operand types are std::ostream << Widget
        // cout << w1 << '\n';
    }

    // However these two work
    {
        w1 << cout << '\n';

        // Call to w1.operator<<(cout) returns a reference to ostream&
        w2 << w1.operator<<(cout) << '\n';
    }

    return 0;
}

So to sum it up - you can do it, but you most probably shouldn't :)

sumr is implemented in terms of foldRight:

 final def sumr(implicit A: Monoid[A]): A = F.foldRight(self, A.zero)(A.append) 

foldRight is not always tail recursive, so you can overflow the stack if the collection is too long. See Why foldRight and reduceRight are NOT tail recursive? for some more discussion of when this is or isn't true.

window.history.pushState({urlPath:'/page1'},"",'/page1')

Only works after page is loaded, and when you will click on refresh it doesn't mean that there is any real URL.

What you should do here is knowing to which URL you are getting redirected when you reload this page. And on that page you can get the conditions by getting the current URL and making all of your conditions.

The highest voted answer (MishieMoo) is correct but it doesn't explain how to open Podfile.lock. Everytime I tried I kept getting:

You open it in terminal by going to the folder it's in and running:

vim Podfile.lock

I got the answer from here: how to open Podfile.lock

You close it by pressing the colon and typing quit or by pressing the colon and the letter q then enter

:quit // then return key
:q // then return key

Another way is in terminal, you can also cd to the folder that your Xcode project is in and enter

$ open Podfile.lock -a Xcode

Doing it the second way, after it opens just press the red X button in the upper left hand corner to close.

If you will use the image in multiple places, then it's worth loading the image data only once into memory and then sharing it between all Image elements.

To do this, create a BitmapSource as a resource somewhere:

<BitmapImage x:Key="MyImageSource" UriSource="../Media/Image.png" />

Then, in your code, use something like:

<Image Source="{StaticResource MyImageSource}" />

In my case, I found that I had to set the Image.png file to have a build action of Resource rather than just Content. This causes the image to be carried within your compiled assembly.

I arrived at this page looking to turn off scale mode for good, so I figured I would share what I found:

VBoxManage setextradata global GUI/Input/MachineShortcuts "ScaleMode=None"

Running this in my host's terminal worked like a charm for me.

Both null and an empty string are falsy values in JS. Therefore,

if (data) { ... }

is completely sufficient.

A note on the side though: I would avoid having a variable in my code that could manifest in different types. If the data will eventually be a string, then I would initially define my variable with an empty string, so you can do this:

if (data !== '') { ... }

without the null (or any weird stuff like data = "0") getting in the way.

As csgillespie said. stringsAsFactors is default on TRUE, which converts any text to a factor. So even after deleting the text, you still have a factor in your dataframe.

Now regarding the conversion, there's a more optimal way to do so. So I put it here as a reference :

> x <- factor(sample(4:8,10,replace=T))
> x
 [1] 6 4 8 6 7 6 8 5 8 4
Levels: 4 5 6 7 8
> as.numeric(levels(x))[x]
 [1] 6 4 8 6 7 6 8 5 8 4

To show it works.

The timings :

> x <- factor(sample(4:8,500000,replace=T))
> system.time(as.numeric(as.character(x)))
   user  system elapsed 
   0.11    0.00    0.11 
> system.time(as.numeric(levels(x))[x])
   user  system elapsed 
      0       0       0 

It's a big improvement, but not always a bottleneck. It gets important however if you have a big dataframe and a lot of columns to convert.

Your usage of &>x.file does work in bash4. sorry for that : (

Here comes some additional tips.

0, 1, 2...9 are file descriptors in bash.

0 stands for stdin, 1 stands for stdout, 2 stands for stderror. 3~9 is spare for any other temporary usage.

Any file descriptor can be redirected to other file descriptor or file by using operator > or >>(append).

Usage: <file_descriptor> > <filename | &file_descriptor>

Please reference to http://www.tldp.org/LDP/abs/html/io-redirection.html

If you have multiple directories in your test directory, then you have to add to each directory an __init__.py file.

/home/johndoe/snakeoil
+-- test
    +-- __init__.py        
    +-- frontend
        +-- __init__.py
        +-- test_foo.py
    +-- backend
        +-- __init__.py
        +-- test_bar.py

Then to run every test at once, run:

python -m unittest discover -s /home/johndoe/snakeoil/test -t /home/johndoe/snakeoil

Source: python -m unittest -h

  -s START, --start-directory START
                        Directory to start discovery ('.' default)
  -t TOP, --top-level-directory TOP
                        Top level directory of project (defaults to start
                        directory)

This answer suggests optparse which is appropriate for older Python versions. For Python 2.7 and above, argparse replaces optparse. See this answer for more information.

As other people pointed out, you are better off going with optparse over getopt. getopt is pretty much a one-to-one mapping of the standard getopt(3) C library functions, and not very easy to use.

optparse, while being a bit more verbose, is much better structured and simpler to extend later on.

Here's a typical line to add an option to your parser:

parser.add_option('-q', '--query',
            action="store", dest="query",
            help="query string", default="spam")

It pretty much speaks for itself; at processing time, it will accept -q or --query as options, store the argument in an attribute called query and has a default value if you don't specify it. It is also self-documenting in that you declare the help argument (which will be used when run with -h/--help) right there with the option.

Usually you parse your arguments with:

options, args = parser.parse_args()

This will, by default, parse the standard arguments passed to the script (sys.argv[1:])

options.query will then be set to the value you passed to the script.

You create a parser simply by doing

parser = optparse.OptionParser()

These are all the basics you need. Here's a complete Python script that shows this:

import optparse

parser = optparse.OptionParser()

parser.add_option('-q', '--query',
    action="store", dest="query",
    help="query string", default="spam")

options, args = parser.parse_args()

print 'Query string:', options.query

5 lines of python that show you the basics.

Save it in sample.py, and run it once with

python sample.py

and once with

python sample.py --query myquery

Beyond that, you will find that optparse is very easy to extend. In one of my projects, I created a Command class which allows you to nest subcommands in a command tree easily. It uses optparse heavily to chain commands together. It's not something I can easily explain in a few lines, but feel free to browse around in my repository for the main class, as well as a class that uses it and the option parser

for(var i = 0; i < restaurants.length; i++)
{
  if(restaurants[i].restaurant.food == 'chicken')
  {
    return restaurants[i].restaurant.name;
  }
}

Regarding your code: It's slightly hard to read... If you want to try to view it all in a php array format, just print_r it. This might help:

In the first line of your JS code:

select.addEventListener('change', getSelection(this), false);

you're invoking getSelection by placing (this) behind the function reference. That is most likely not what you want, because you're now passing the return value of that call to addEventListener, instead of a reference to the actual function itself.

In a function invoked by addEventListener the value for this will automatically be set to the object the listener is attached to, productLineSelect in this case.

If that is what you want, you can just pass the function reference and this will in this example be select in invocations from addEventListener:

select.addEventListener('change', getSelection, false);

If that is not what you want, you'd best bind your value for this to the function you're passing to addEventListener:

var thisArg = { custom: 'object' };
select.addEventListener('change', getSelection.bind(thisArg), false);

The .bind part is also a call, but this call just returns the same function we're calling bind on, with the value for this inside that function scope fixed to thisArg, effectively overriding the dynamic nature of this-binding.

To get to your actual question: "How to pass parameters to function in addEventListener?"

You would have to use an additional function definition:

var globalVar = 'global';

productLineSelect.addEventListener('change', function(event) {
    var localVar = 'local';
    getSelection(event, this, globalVar, localVar);
}, false);

Now we pass the event object, a reference to the value of this inside the callback of addEventListener, a variable defined and initialised inside that callback, and a variable from outside the entire addEventListener call to your own getSelection function.

We also might again have an object of our choice to be this inside the outer callback:

var thisArg = { custom: 'object' };
var globalVar = 'global';

productLineSelect.addEventListener('change', function(event) {
    var localVar = 'local';
    getSelection(event, this, globalVar, localVar);
}.bind(thisArg), false);

I am using Laravel 5.4 and response()->file('path/to/file.ext') to open e.g. a pdf in inline-mode in browsers. This works quite well, but when a user wants to save the file, the save-dialog suggests the last part of the url as filename.

I already tried adding a headers-array like mentioned in the Laravel-docs, but this doesn't seem to override the header set by the file()-method:

return response()->file('path/to/file.ext', [
  'Content-Disposition' => 'inline; filename="'. $fileNameFromDb .'"'
]);

You can use drop command to delete meta data and actual data from HDFS.

And just to delete data and keep the table structure, use truncate command.

For further help regarding hive ql, check language manual of hive.

Use something like header( 'Location: /my-other-page.html' ); to redirect. You can't have sent any other data on the page before you do this though.

I'm not sure whether it works with two syncing but for the --delete to work you also need to add the --recursive parameter as well.

TextView textv = (TextView) findViewById(R.id.textview1);
textv.setShadowLayer(1, 0, 0, Color.BLACK);

Most of the answers here are offering to delete random files.

Most of the time, this is the worst thing to do especially if it is important for you to keep the integrity of your development environment.

As explained in the log file, if this problem is not related to a read access permission nor to a file you deleted in your mysql then the only solution is to:

Open your my.conf file from the File menu in MAMP (File > Edit Template > MySQL)

Find and edit this line to be: innodb_force_recovery = 1

Save with ctrl+S

MAMP will offer you to restart your servers

Go back building the next unicorn :)

In windows 7, you may have to edit this file

Try this

Months.values()[index]

@tableName Table variables are alive for duration of the script running only i.e. they are only session level objects.

To test this, open two query editor windows under sql server management studio, and create table variables with same name but different structures. You will get an idea. The @tableName object is thus temporary and used for our internal processing of data, and it doesn't contribute to the actual database structure.

There is another type of table object which can be created for temporary use. They are #tableName objects declared like similar create statement for physical tables:

Create table #test (Id int, Name varchar(50))

This table object is created and stored in temp database. Unlike the first one, this object is more useful, can store large data and takes part in transactions etc. These tables are alive till the connection is open. You have to drop the created object by following script before re-creating it.

IF OBJECT_ID('tempdb..#test') IS NOT NULL
  DROP TABLE #test 

Hope this makes sense !

To add to tacaswell's answer, the colorbar() function has an optional cax input you can use to pass an axis on which the colorbar should be drawn. If you are using that input, you can directly set a label using that axis.

import matplotlib.pyplot as plt
from mpl_toolkits.axes_grid1 import make_axes_locatable

fig, ax = plt.subplots()
heatmap = ax.imshow(data)
divider = make_axes_locatable(ax)
cax = divider.append_axes('bottom', size='10%', pad=0.6)
cb = fig.colorbar(heatmap, cax=cax, orientation='horizontal')

cax.set_xlabel('data label')  # cax == cb.ax

My database was larger than 500mb, I then used the following

C:\Windows>sqlcmd -S SERVERNAME -U USERNAME -P PASSWORD -d DATABASE -i C:\FILE.sql

It loaded everything including SP's

*NB: Run the cmd as Administrator

By exporting the SPARK path and the Py4j path, it started to work:

export SPARK_HOME=/usr/local/Cellar/apache-spark/1.5.1
export PYTHONPATH=$SPARK_HOME/libexec/python:$SPARK_HOME/libexec/python/build:$PYTHONPATH
PYTHONPATH=$SPARK_HOME/python/lib/py4j-0.8.2.1-src.zip:$PYTHONPATH 
export PYTHONPATH=$SPARK_HOME/python:$SPARK_HOME/python/build:$PYTHONPATH

So, if you don't want to type these everytime you want to fire up the Python shell, you might want to add it to your .bashrc file

To replace a string in your HTML with another use the replace method on innerHTML:

document.body.innerHTML = document.body.innerHTML.replace('hello', 'hi');

Note that this will replace the first instance of hello throughout the body, including any instances in your HTML code (e.g. class names etc..), so use with caution - for better results, try restricting the scope of your replacement by targeting your code using document.getElementById or similar.

To replace all instances of the target string, use a simple regular expression with the global flag:

document.body.innerHTML = document.body.innerHTML.replace(/hello/g, 'hi');

[NSTimer scheduledTimerWithTimeInterval:.06 target:self selector:@selector(goToSecondButton:) userInfo:nil repeats:NO];

Is the best one to use. Using sleep(15); will cause the user unable to perform any other actions. With the following function, you would replace goToSecondButton with the appropriate selector or command, which can also be from the frameworks.

mcc -?

explains that the syntax to make *.exe (Standalone Application) with *.m is:

 mcc -m <matlabFile.m> 

For example:

mcc -m file.m

will create file.exe in the curent directory.

One way to handle this is to create a new BufferedImage, and tell it's graphics object to draw your scaled image into the new BufferedImage:

final float FACTOR  = 4f;
BufferedImage img = ImageIO.read(new File("graphic.png"));
int scaleX = (int) (img.getWidth() * FACTOR);
int scaleY = (int) (img.getHeight() * FACTOR);
Image image = img.getScaledInstance(scaleX, scaleY, Image.SCALE_SMOOTH);
BufferedImage buffered = new BufferedImage(scaleX, scaleY, TYPE);
buffered.getGraphics().drawImage(image, 0, 0 , null);

That should do the trick without casting.

Consider making your route:

_files_manage:
    pattern: /files/management/{project}/{user}
    defaults: { _controller: AcmeTestBundle:File:manage }

since they are required fields. It will make your url's prettier, and be a bit easier to manage.

Your Controller would then look like

 public function projectAction($project, $user)

I had the same problem, I tried to update my password using windows credential manager, it still didn't fix the issue

Control Panel --> Credential Manager --> Manage Windows Credentials --> Choose the entry of the git repository, and Edit the user and password.

I then deleted all the git related entry in credentials manager and then tried to use Git using visual studio, this time it prompted for new credentials

All right after trying every solution on the web I ended up figuare out the issue using very simple method , first I cheked php-fpm err log

cat /var/log/php5-fpm.log 

and the most repeated error was

" WARNING: [pool www] server reached pm.max_children setting (5), consider raising it "

I edit PHP-fpm pools setting

nano /etc/php5/fpm/pool.d/www.conf

I chenged This Line

pm.max_children = 5

To new Value

pm.max_children = 10

BTW I'm using low end VPS with 128MB ram As everyone else I was thinkin redusing pm.max_children will make my server run faster consume less memory , but the setting we using were too low tho even start PHP-fpm process . I hope this help others since I found this after 24 hour testing and failing , ever my webhost support were not able to solve the issue .

The answer by Nick Mitchinson is for Bootstrap version 2.

If you are using Bootstrap version 3, then forms have changed a bit. For bootstrap 3, use the following instead:

<div class="form-horizontal">
    <div class="form-group">
        <div class="col-md-6">
            <textarea class="form-control" rows="3" placeholder="What's up?" required></textarea>
        </div>
    </div>
</div>

Where, col-md-6 will target medium sized devices. You can add col-xs-6 etc to target smaller devices.

There is one more option to rename field:

Jackson MixIns.

Useful if you deal with third party classes, which you are not able to annotate, or you just do not want to pollute the class with Jackson specific annotations.

The Jackson documentation for Mixins is outdated, so this example can provide more clarity. In essence: you create mixin class which does the serialization in the way you want. Then register it to the ObjectMapper:

objectMapper.addMixIn(ThirdParty.class, MyMixIn.class);

Tested On Ubuntu 20, sudo chown -R $USER:$USER /var/www

Heres my solution as of 5.4:

//Auth::routes();
// Authentication Routes...
Route::get('login', 'Auth\LoginController@showLoginForm')->name('login');
Route::post('login', 'Auth\LoginController@login');
Route::post('logout', 'Auth\LoginController@logout')->name('logout');

// Registration Routes...
//Route::get('register', 'Auth\RegisterController@showRegistrationForm')->name('register');
//Route::post('register', 'Auth\RegisterController@register');

// Password Reset Routes...
Route::get('password/reset', 'Auth\ForgotPasswordController@showLinkRequestForm')->name('password.request');
Route::post('password/email', 'Auth\ForgotPasswordController@sendResetLinkEmail')->name('password.email');
Route::get('password/reset/{token}', 'Auth\ResetPasswordController@showResetForm')->name('password.reset');
Route::post('password/reset', 'Auth\ResetPasswordController@reset');

Notice I've commented out Auth::routes() and the two registration routes.

Important: you must also make sure you remove all instances of route('register') in your app.blade layout, or Laravel will throw an error.

You can use ::after to create a 0px-height block after the <h4>, which effectively moves anything after the <h4> to the next line:

h4 {_x000D_
  display: inline;_x000D_

I now recommend the use of Carbon

As of CMake Wiki:

CMAKE_BINARY_DIR if you are building in-source, this is the same as CMAKE_SOURCE_DIR, otherwise this is the top level directory of your build tree

Compare these two variables to determine if out-of-source build was started

MySQL has drivers for many other languages, converting data to string "standardizes" data and leaves it up to the user to type-cast values to int or others

Good answers above explaining the actual question from the OP.

If anyone needs to pass around a number that needs to be globally updated, use the AtomicInteger() instead of creating the various wrapper classes suggested or relying on 3rd party libs.

The AtomicInteger() is of course mostly used for thread safe access but if the performance hit is no issue, why not use this built-in class. The added bonus is of course the obvious thread safety.

Change the value for Platform Target on your web project's property page to Any CPU.

The NULL part is calculated AFTER the actual join, so that is why it needs to be in the where clause.

CSV isn't quite that simple. Depending on the limits of the data you have, you might have to worry about quoted values (which may contain commas and newlines) and escaping quotes.

So if your data are restricted enough can get away with simple comma-splitting fine, shell script can do that easily. If, on the other hand, you need to parse CSV ‘properly’, bash would not be my first choice. Instead I'd look at a higher-level scripting language, for example Python with a csv.reader.

The return statement only makes sense inside functions:

def foo():
    while True:
        return False

Select * from Table1 t1 Left Join Table2 t2 on t1.id=t2.id By definition: Left Join selects all columns mentioned with the "select" keyword from Table 1 and the columns from Table 2 which matches the criteria after the "on" keyword.

Similarly,By definition: Right Join selects all columns mentioned with the "select" keyword from Table 2 and the columns from Table 1 which matches the criteria after the "on" keyword.

Referring to your question, id's in both the tables are compared with all the columns needed to be thrown in the output. So, ids 1 and 2 are common in the both the tables and as a result in the result you will have four columns with id and name columns from first and second tables in order.

*select * from Table1 left join Table2 on Table1.id = Table2.id

The above expression,it takes all the records (rows) from table 1 and columns, with matching id's from table 1 and table 2, from table 2.

select * from Table2 right join Table1 on Table1.id = Table2.id**

Similarly from the above expression,it takes all the records (rows) from table 1 and columns, with matching id's from table 1 and table 2, from table 2. (remember, this is a right join so all the columns from table2 and not from table1 will be considered).

{ "date" : "1000000" } in your Mongo doc seems suspect. Since it's a number, it should be { date : 1000000 }

It's probably a type mismatch. Try post.findOne({date: "1000000"}, callback) and if that works, you have a typing issue.

Try this

function isValidEmailAddress(emailAddress) {
    var pattern = new RegExp(/^([a-zA-Z0-9_\.\-])+\@(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9]{2,4})+$/);
    return pattern.test(emailAddress);
};

If you are using SQL Azure Reporting Services, the "format" function is unsupported. This is really the only way to format a tooltip in a chart in SSRS. So the workaround is to return a column that has a string representation of the formatted number to use for the tooltip. So, I do agree that SQL is not the place for formatting. Except in cases like this where the tool does not have proper functions to handle display formatting.

In my case I needed to show a number formatted with commas and no decimals (type decimal 2) and ended up with this gem of a calculated column in my dataset query:

,Fmt_DDS=reverse(stuff(reverse(CONVERT(varchar(25),cast(SUM(kv.DeepDiveSavingsEst) as money),1)), 1, 3, ''))

It works, but is very ugly and non-obvious to whoever maintains the report down the road. Yay Cloud!

For those looking for a dynamic solution to embed Matplotlib in PyQt5 (even plot data using drag and drop). In PyQt5 you need to use super on the main window class to accept the drops. The dropevent function can be used to get the filename and rest is simple:

def dropEvent(self,e):
        """
        This function will enable the drop file directly on to the 
        main window. The file location will be stored in the self.filename
        """
        if e.mimeData().hasUrls:
            e.setDropAction(QtCore.Qt.CopyAction)
            e.accept()
            for url in e.mimeData().urls():
                if op_sys == 'Darwin':
                    fname = str(NSURL.URLWithString_(str(url.toString())).filePathURL().path())
                else:
                    fname = str(url.toLocalFile())
            self.filename = fname
            print("GOT ADDRESS:",self.filename)
            self.readData()
        else:
            e.ignore() # just like above functions  

For starters the reference complete code gives this output:

I just realized that the hist documentation is explicit about what to do when you already have an np.histogram

counts, bins = np.histogram(data)
plt.hist(bins[:-1], bins, weights=counts)

The important part here is that your counts are simply the weights. If you do it like that, you don't need the bar function anymore

This can also happen when the log file is restricted in size.

You can see the kernel version by typing uname -r. It'll be 2.6.something.

This is a quirk of the C grammar. A label (Cleanup:) is not allowed to appear immediately before a declaration (such as char *str ...;), only before a statement (printf(...);). In C89 this was no great difficulty because declarations could only appear at the very beginning of a block, so you could always move the label down a bit and avoid the issue. In C99 you can mix declarations and code, but you still can't put a label immediately before a declaration.

You can put a semicolon immediately after the label's colon (as suggested by Renan) to make there be an empty statement there; this is what I would do in machine-generated code. Alternatively, hoist the declaration to the top of the function:

int main (void) 
{
    char *str;
    printf("Hello ");
    goto Cleanup;
Cleanup:
    str = "World\n";
    printf("%s\n", str);
    return 0;
}

So I found a pretty good answer at this link: https://www.thomasmaurer.ch/2011/03/powershell-search-for-string-or-grep-for-powershell/

But essentially it is:

Select-String -Path "C:\file\Path\*.txt" -Pattern "^Enter REGEX Here$"

This gives a directory file search (*or you can just specify a file) and a file-content search all in one line of PowerShell, very similar to grep. The output will be similar to:

doc.txt:31: Enter REGEX Here
HelloWorld.txt:13: Enter REGEX Here

Did you run mongod before running mongo?

I followed installation instructions for mongodb from http://docs.mongodb.org/manual/tutorial/install-mongodb-on-os-x/ and I had the same error as you only when I ran mongo before actually running the mongo process with mongod. I thought installing mongodb would also launch it but you need to launch it manually with mongod before you do anything else that needs mongodb.

You can define a table dynamically just as you are inserting into it dynamically, but the problem is with the scope of temp tables. For example, this code:

DECLARE @sql varchar(max)
SET @sql = 'CREATE TABLE #T1 (Col1 varchar(20))'
EXEC(@sql)
INSERT INTO #T1 (Col1) VALUES ('This will not work.')
SELECT * FROM #T1

will return with the error "Invalid object name '#T1'." This is because the temp table #T1 is created at a "lower level" than the block of executing code. In order to fix, use a global temp table:

DECLARE @sql varchar(max)
SET @sql = 'CREATE TABLE ##T1 (Col1 varchar(20))'
EXEC(@sql)
INSERT INTO ##T1 (Col1) VALUES ('This will work.')
SELECT * FROM ##T1

Hope this helps, Jesse

Functions like sine and cosine are implemented in microcode inside microprocessors. Intel chips, for example, have assembly instructions for these. A C compiler will generate code that calls these assembly instructions. (By contrast, a Java compiler will not. Java evaluates trig functions in software rather than hardware, and so it runs much slower.)

Chips do not use Taylor series to compute trig functions, at least not entirely. First of all they use CORDIC, but they may also use a short Taylor series to polish up the result of CORDIC or for special cases such as computing sine with high relative accuracy for very small angles. For more explanation, see this StackOverflow answer.

All your problems are that you are mixing content type negotiation with parameter passing. They are things at different levels. More specific, for your question 2, you constructed the response header with the media type your want to return. The actual content negotiation is based on the accept media type in your request header, not response header. At the point the execution reaches the implementation of the method getPersonFormat, I am not sure whether the content negotiation has been done or not. Depends on the implementation. If not and you want to make the thing work, you can overwrite the request header accept type with what you want to return.

return new ResponseEntity<>(PersonFactory.createPerson(), httpHeaders, HttpStatus.OK);

Well, I have a tricky method for this job. The idea is as follow-

Make some invisible HTML tags like <label>, <p>, <input> etc. in HTML body and make a pattern in tag id, for example, use list index in tag id and list value at tag class name.

Here I have two lists maintenance_next[] and maintenance_block_time[] of the same length. I want to pass these two list's data to javascript using the flask. So I take some invisible label tag and set its tag name is a pattern of list index and set its class name as value at index.

{% for i in range(maintenance_next|length): %}_x000D_
<label id="maintenance_next_{{i}}" name="{{maintenance_next[i]}}" style="display: none;"></label>_x000D_
<label id="maintenance_block_time_{{i}}" name="{{maintenance_block_time[i]}}" style="display: none;"></label>_x000D_
{% endfor%}

After this, I retrieve the data in javascript using some simple javascript operation.

<script>_x000D_
var total_len = {{ total_len }};_x000D_
_x000D_
for (var i = 0; i < total_len; i++) {_x000D_
    var tm1 = document.getElementById("maintenance_next_" + i).getAttribute("name");_x000D_
    var tm2 = document.getElementById("maintenance_block_time_" + i).getAttribute("name");_x000D_
    _x000D_
    //Do what you need to do with tm1 and tm2._x000D_
    _x000D_
    console.log(tm1);_x000D_
    console.log(tm2);_x000D_
}_x000D_
</script>

var table = document.getElementById("someTableID"); 
var totalRows = document.getElementById("someTableID").rows.length;
var totalCol = 3; // enter the number of columns in the table minus 1 (first column is 0 not 1)
//To display all values
for (var x = 0; x <= totalRows; x++)
  {
  for (var y = 0; y <= totalCol; y++)
    {
    alert(table.rows[x].cells[y].innerHTML;
    }
  }
//To display a single cell value enter in the row number and column number under rows and cells below:
var firstCell = table.rows[0].cells[0].innerHTML;
alert(firstCell);
//Note:  if you use <th> this will be row 0, so your data will start at row 1 col 0

This is the fastest Java implementation I could come up with, using a combination of techniques suggested by others in this thread.

• Mod-256 test
• Inexact mod-3465 test (avoids integer division at the cost of some false positives)
• Floating-point square root, round and compare with input value

I also experimented with these modifications but they did not help performance:

• Additional mod-255 test
• Dividing the input value by powers of 4
• Fast Inverse Square Root (to work for high values of N it needs 3 iterations, enough to make it slower than the hardware square root function.)

I have read that it is used for optimizing but is not clearly defined in any standard.

In fact it is clearly defined by the C standard. Quoting the N1570 draft section 6.7.1 paragraph 6 (other versions have the same wording):

A declaration of an identifier for an object with storage-class specifier register suggests that access to the object be as fast as possible. The extent to which such suggestions are effective is implementation-defined.

The unary & operator may not be applied to an object defined with register, and register may not be used in an external declaration.

There are a few other (fairly obscure) rules that are specific to register-qualified objects:

• Defining an array object with register has undefined behavior.
  Correction: It's legal to define an array object with register, but you can't do anything useful with such an object (indexing into an array requires taking the address of its initial element).
• The _Alignas specifier (new in C11) may not be applied to such an object.
• If the parameter name passed to the va_start macro is register-qualified, the behavior is undefined.

There may be a few others; download a draft of the standard and search for "register" if you're interested.

As the name implies, the original meaning of register was to require an object to be stored in a CPU register. But with improvements in optimizing compilers, this has become less useful. Modern versions of the C standard don't refer to CPU registers, because they no longer (need to) assume that there is such a thing (there are architectures that don't use registers). The common wisdom is that applying register to an object declaration is more likely to worsen the generated code, because it interferes with the compiler's own register allocation. There might still be a few cases where it's useful (say, if you really do know how often a variable will be accessed, and your knowledge is better than what a modern optimizing compiler can figure out).

The main tangible effect of register is that it prevents any attempt to take an object's address. This isn't particularly useful as an optimization hint, since it can be applied only to local variables, and an optimizing compiler can see for itself that such an object's address isn't taken.

My approach was to make a slight command line variant that adds the registry switch.

I created these files in the nodejs folder where the npm executable is found:

npm-.cmd:

@ECHO OFF
npm --registry https://registry.npmjs.org %*

npm-:

#!/bin/sh
"npm" --registry https://registry.npmjs.org "$@"

Now, if I want to do an operation against the normal npm registry (while I am not connected to the VPN), I just type npm- where I would usually type npm.

To test this command and see the registry for a package, use this example:

npm- view lodash

PS. I am in windows and have tested this in Bash, CMD, and Powershell. I also

You do not need to calculate tree depths on the fly.

You can maintain them as you perform operations.

Furthermore, you don't actually in fact have to maintain track of depths; you can simply keep track of the difference between the left and right tree depths.

http://www.eternallyconfuzzled.com/tuts/datastructures/jsw_tut_avl.aspx

Just keeping track of the balance factor (difference between left and right subtrees) is I found easier from a programming POV, except that sorting out the balance factor after a rotation is a PITA...

There is an open source project called auto-py-to-exe on GitHub. Actually it also just uses PyInstaller internally but since it is has a simple GUI that controls PyInstaller it may be a comfortable alternative. It can also output a standalone file in contrast to other solutions. They also provide a video showing how to set it up.

GUI:

Output:

• In the Code::Blocks IDE, navigate Settings -> Debugger

• In the tree control at the right, select Common -> GDB/CDB debugger -> Common.

• Then in the dialog at the left you can enter Executable path and choose Debugger type = GDB or CDB, as well as configuring various other options.

Setting command timeout to 2 minutes.

 scGetruntotals.CommandTimeout = 120;

but you can optimize your stored Procedures to decrease that time! like

• removing courser or while and etc
• using paging
• using #tempTable and @variableTable
• optimizing joined tables

The new version of SharePoint and Office (SharePoint 2010 and Office 2010) respectively are supposed to allow for this. This also includes the web based versions. I have seen Word and Excel in action do this, not sure about other client applications.

I am not sure about the specific implementation features you are asking about in terms of security though. Sorry.,=

Here is a discussion

http://blogs.msdn.com/b/sharepoint/archive/2009/10/19/sharepoint-2010.aspx

Using pathlib (https://docs.python.org/3/library/pathlib.html)

from pathlib import Path
file = Path('Stud.txt')
file.write_text(file.read_text().replace('A', 'Orange'))

If input and output files were different you would use two different variables for read_text and write_text.

If you wanted a change more complex than a single replacement, you would assign the result of read_text to a variable, process it and save the new content to another variable, and then save the new content with write_text.

If your file was large you would prefer an approach that does not read the whole file in memory, but rather process it line by line as show by Gareth Davidson in another answer (https://stackoverflow.com/a/4128192/3981273), which of course requires to use two distinct files for input and output.

You can encode HTML like this .

You could try:

$rows = array();
while($row = mysql_fetch_array($result)){
  array_push($rows, $row);
}
echo json_encode($rows);

Note that this may also work:

SELECT * FROM table WHERE s=ANY(array)

Snapshot simply means depending on your configuration Maven will check latest changes on a special dependency. Snapshot is unstable because it is under development but if on a special project needs to has a latest changes you must configure your dependency version to snapshot version. This scenario occurs in big organizations with multiple products that these products related to each other very closely.

No, it needs three operands. That's why they're called ternary operators.

However, for what you have as your example, you can do this:

if(condition) x = true;

Although it's safer to have braces if you need to add more than one statement in the future:

if(condition) { x = true; }

Edit: Now that you mention the actual code in which your question applies to:

if(!defaults.slideshowWidth)
    { defaults.slideshowWidth = obj.find('img').width()+'px'; }

Elements are added to list using append():

>>> data = {'list': [{'a':'1'}]}
>>> data['list'].append({'b':'2'})
>>> data
{'list': [{'a': '1'}, {'b': '2'}]}

If you want to add element to a specific place in a list (i.e. to the beginning), use insert() instead:

>>> data['list'].insert(0, {'b':'2'})
>>> data
{'list': [{'b': '2'}, {'a': '1'}]}

After doing that, you can assemble JSON again from dictionary you modified:

>>> json.dumps(data)
'{"list": [{"b": "2"}, {"a": "1"}]}'

Inspired by Alex K's reply One way (2k8), I have created a script for a Token Function for the SQL Server for returning a specific token from a string. I needed this for refacturing a SSIS-package to T-SQL without having to implement Alex' solution a number of times manually. My function has one disadvantage: It returns the token value as a table (one column, one row) instead of as a varchar value. If anyone has a solution for this, please let me know.

DROP FUNCTION [RDW].[token]
GO

create function [RDW].[token] (@string varchar(8000), @split varchar(50), @returnIndex int) 
returns table  
as 
    return with T(img, starts, pos, [index]) as ( 
        select @string, 1, charindex(@split, @string), 0 
        union all 
        select @string, pos + 1, charindex(@split, @string, pos + 1), [index]+1 
        from t 
        where pos > 0
    )
    select substring(img, starts, case when pos > 0 then pos - starts else len(img) end) token
    from T
    where [index] = @returnIndex 
GO

A clean way without having to uninstall a previous version or reverting to additional software like Anaconda or docker, etc. is to download the Python 3.6 source code and install it as follows:

$ mkdir /home/<user>/python3.6
$ ./configure --prefix=/home/<user>/python3.6/
$ make altinstall

To use it you either:

• add /home/<user>/python3.6/bin to your PATH (and lib to LD_LIBRARY_PATH) and be done with it. (You may also need to add to your include path etc., depending on what you're trying to achieve exactly - but you get the idea, I hope.);

• or, you create a virtual environment similar to this: /home/<user>/python3.6/bin/python3.6 -m venv env-python3.6.

No sudo or root access required. No messing up your system.

Adding .dockerignore works for me. One additional point Those who are trying this solution on Windows , windows will not let you create .dockerignore file (as it doesn't by default allows creating file starting with .)

To create such file starting with . on Windows, include an ending dot also, like : .dockerignore. and hit enter ( provided you have enabled view extension options from folder options )

@Nat gave a good answer. But since there is no way to shorten a code, why not use contatenate to 'generate' the code you need. It works for me when I'm lazy (at typing the whole code in the cell).

So what we need is just identify the pattern > use excel to built the pattern 'structure' > add " = " and paste it in the intended cell.

For example, you want to achieve (i mean, enter in the cell) :

=IF('testsheet'!$C$1 <= 99,'testsheet'!$A$1,"") &IF('testsheet'!$C$2 <= 99,'testsheet'!$A$2,"") &IF('testsheet'!$C$3 <= 99,'testsheet'!$A$3,"") &IF('testsheet'!$C$4 <= 99,'testsheet'!$A$4,"") &IF('testsheet'!$C$5 <= 99,'testsheet'!$A$5,"") &IF('testsheet'!$C$6 <= 99,'testsheet'!$A$6,"") &IF('testsheet'!$C$7 <= 99,'testsheet'!$A$7,"") &IF('testsheet'!$C$8 <= 99,'testsheet'!$A$8,"") &IF('testsheet'!$C$9 <= 99,'testsheet'!$A$9,"") &IF('testsheet'!$C$10 <= 99,'testsheet'!$A$10,"") &IF('testsheet'!$C$11 <= 99,'testsheet'!$A$11,"") &IF('testsheet'!$C$12 <= 99,'testsheet'!$A$12,"") &IF('testsheet'!$C$13 <= 99,'testsheet'!$A$13,"") &IF('testsheet'!$C$14 <= 99,'testsheet'!$A$14,"") &IF('testsheet'!$C$15 <= 99,'testsheet'!$A$15,"") &IF('testsheet'!$C$16 <= 99,'testsheet'!$A$16,"") &IF('testsheet'!$C$17 <= 99,'testsheet'!$A$17,"") &IF('testsheet'!$C$18 <= 99,'testsheet'!$A$18,"") &IF('testsheet'!$C$19 <= 99,'testsheet'!$A$19,"") &IF('testsheet'!$C$20 <= 99,'testsheet'!$A$20,"") &IF('testsheet'!$C$21 <= 99,'testsheet'!$A$21,"") &IF('testsheet'!$C$22 <= 99,'testsheet'!$A$22,"") &IF('testsheet'!$C$23 <= 99,'testsheet'!$A$23,"") &IF('testsheet'!$C$24 <= 99,'testsheet'!$A$24,"") &IF('testsheet'!$C$25 <= 99,'testsheet'!$A$25,"") &IF('testsheet'!$C$26 <= 99,'testsheet'!$A$26,"") &IF('testsheet'!$C$27 <= 99,'testsheet'!$A$27,"") &IF('testsheet'!$C$28 <= 99,'testsheet'!$A$28,"") &IF('testsheet'!$C$29 <= 99,'testsheet'!$A$29,"") &IF('testsheet'!$C$30 <= 99,'testsheet'!$A$30,"") &IF('testsheet'!$C$31 <= 99,'testsheet'!$A$31,"") &IF('testsheet'!$C$32 <= 99,'testsheet'!$A$32,"") &IF('testsheet'!$C$33 <= 99,'testsheet'!$A$33,"") &IF('testsheet'!$C$34 <= 99,'testsheet'!$A$34,"") &IF('testsheet'!$C$35 <= 99,'testsheet'!$A$35,"") &IF('testsheet'!$C$36 <= 99,'testsheet'!$A$36,"") &IF('testsheet'!$C$37 <= 99,'testsheet'!$A$37,"") &IF('testsheet'!$C$38 <= 99,'testsheet'!$A$38,"") &IF('testsheet'!$C$39 <= 99,'testsheet'!$A$39,"") &IF('testsheet'!$C$40 <= 99,'testsheet'!$A$40,"") 

I didn't type it, I just use "&" symbol to combine arranged cell in excel (another file, not the file we are working on).

Notice that :

part1 > IF('testsheet'!$C$

part2 > 1 to 40

part3 > <= 99,'testsheet'!$A$

part4 > 1 to 40

part5 > ,"") &

• Enter part1 to A1, part3 to C1, part to E1.
• Enter " = A1 " in A2, " = C1 " in C2, " = E1 " in E2.
• Enter " = B1+1 " in B2, " = D1+1 " in D2.
• Enter " =A2&B2&C2&D2&E2 " in G2
• Enter " =I1&G2 " in I2

Now select A2:I2 , and drag it down. Notice that the number did the increament per row added, and the generated text is combined, cell by cell and line by line.

• Copy I41 content,
• paste it somewhere, add " = " in front, remove the extra & and the back.

Result = code as you intended.

I've use excel/OpenOfficeCalc to help me generate code for my projects. Works for me, hope it helps for others. (:

Likely you will not only need to split into train and test, but also cross validation to make sure your model generalizes. Here I am assuming 70% training data, 20% validation and 10% holdout/test data.

Check out the np.split:

If indices_or_sections is a 1-D array of sorted integers, the entries indicate where along axis the array is split. For example, [2, 3] would, for axis=0, result in

ary[:2] ary[2:3] ary[3:]

t, v, h = np.split(df.sample(frac=1, random_state=1), [int(0.7*len(df)), int(0.9*len(df))]) 

This is helped for me.

For select:

$('select_tags').on('change', function() {
    alert( $(this).find(":selected").val() );
});

For radio/checkbox:

$('radio_tags').on('change', function() {
    alert( $(this).find(":checked").val() );
});

Your question is already three years old and there are some details not covered in other answers:

Most people I know use HomeBrew or MacPorts, I prefer MacPorts because of its clean cut of what is a default Mac OS X environment and my development setup. Just move out your /opt folder and test your packages with a normal user Python environment

MacPorts is only portable within Mac, but with easy_install or pip you will learn how to setup your environment in any platform (Win/Mac/Linux/Bsd...). Furthermore it will always be more up to date and with more packages

I personally let MacPorts handle my Python modules to keep everything updated. Like any other high level package manager (ie: apt-get) it is much better for the heavy lifting of modules with lots of binary dependencies. There is no way I would build my Qt bindings (PySide) with easy_install or pip. Qt is huge and takes a lot to compile. As soon as you want a Python package that needs a library used by non Python programs, try to avoid easy_install or pip

At some point you will find that there are some packages missing within MacPorts. I do not believe that MacPorts will ever give you the whole CheeseShop. For example, recently I needed the Elixir module, but MacPorts only offers py25-elixir and py26-elixir, no py27 version. In cases like these you have:

pip-2.7 install --user elixir

( make sure you always type pip-(version) )

That will build an extra Python library in your home dir. Yes, Python will work with more than one library location: one controlled by MacPorts and a user local one for everything missing within MacPorts.

Now notice that I favor pip over easy_install. There is a good reason you should avoid setuptools and easy_install. Here is a good explanation and I try to keep away from them. One very useful feature of pip is giving you a list of all the modules (along their versions) that you installed with MacPorts, easy_install and pip itself:

pip-2.7 freeze

If you already started using easy_install, don't worry, pip can recognize everything done already by easy_install and even upgrade the packages installed with it.

If you are a developer keep an eye on virtualenv for controlling different setups and combinations of module versions. Other answers mention it already, what is not mentioned so far is the Tox module, a tool for testing that your package installs correctly with different Python versions.

Although I usually do not have version conflicts, I like to have virtualenv to set up a clean environment and get a clear view of my packages dependencies. That way I never forget any dependencies in my setup.py

If you go for MacPorts be aware that multiple versions of the same package are not selected anymore like the old Debian style with an extra python_select package (it is still there for compatibility). Now you have the select command to choose which Python version will be used (you can even select the Apple installed ones):

$  port select python
Available versions for python:
    none
    python25-apple
    python26-apple
    python27 (active)
    python27-apple
    python32

$ port select python python32

Add tox on top of it and your programs should be really portable

@ Attribute string binding (one way) = Two-way model binding & Callback method binding

Little update. There is a hook available for react-cookie

1) First of all, install the dependency (just for a note)

yarn add react-cookie

or

npm install react-cookie

2) My usage example:

// SignInComponent.js
import { useCookies } from 'react-cookie'

const SignInComponent = () => {

// ...

const [cookies, setCookie] = useCookies(['access_token', 'refresh_token'])

async function onSubmit(values) {
    const response = await getOauthResponse(values);

    let expires = new Date()
    expires.setTime(expires.getTime() + (response.data.expires_in * 1000))
    setCookie('access_token', response.data.access_token, { path: '/',  expires})
    setCookie('refresh_token', response.data.refresh_token, {path: '/', expires})

    // ...
}

// next goes my sign-in form

}

Hope it is helpful.

Suggestions to improve the example above are very appreciated!

Here is the complete C# 7 solution...

switch (value)
{
   case var s when new[] { 1,2,3 }.Contains(s):
      // Do something
      break;
   case var s when new[] { 4,5,6 }.Contains(s):
      // Do something
      break;
   default:
      // Do the default
      break;
}

It works with strings too...

switch (mystring)
{
   case var s when new[] { "Alpha","Beta","Gamma" }.Contains(s):
      // Do something
      break;
...
}

def anotherFunction(word):
    for letter in word:              
        print("_", end=" ")

def oneFunction(lists):
    category = random.choice(list(lists.keys()))
    word = random.choice(lists[category])
    return anotherFunction(word)

My two cents:

Spit:

Traceback (most recent call last):
      File "bash\bash.py", line 454, in main
        import bosh
      File "Wrye Bash Launcher.pyw", line 63, in load_module
        mod = imp.load_source(fullname,filename+ext,fp)
      File "bash\bosh.py", line 69, in <module>
        from game.oblivion.RecordGroups import MobWorlds, MobDials, MobICells, \
    ImportError: No module named RecordGroups

This confused the hell out of me - went through posts and posts suggesting ugly syspath hacks (as you see my __init__.py were all there). Well turns out that game/oblivion.py and game/oblivion was confusing python which spit out the rather unhelpful "No module named RecordGroups". I'd be interested in a workaround and/or links documenting this (same name) behavior -> EDIT (2017.01.24) - have a look at What If I Have a Module and a Package With The Same Name? Interestingly normally packages take precedence but apparently our launcher violates this.

EDIT (2015.01.17): I did not mention we use a custom launcher dissected here.

I think doing this way is much simpler:

button.setBackgroundColor(Color.BLACK);

And you need to import android.graphics.Color; not: import android.R.color;

Or you can just write the 4-byte hex code (not 3-byte) 0xFF000000 where the first byte is setting the alpha.

Use extend to add a list comprehension to the end.

l.extend([x for i in range(100)])

See the Python docs for more information.

You can also replace "-moz-user-select:none" with "-moz-user-select:inherit". This will inherit the style value from any parent style or from the default style if no parent style was defined.

Look up the specification of HTTP. Or to get started, try http://www.jmarshall.com/easy/http/

The problem is simple that the PHP-Mail function is not using a well configured SMTP Server.

Nowadays Email-Clients and Servers perform massive checks on the emails sending server, like Reverse-DNS-Lookups, Graylisting and whatevs. All this tests will fail with the php mail() function. If you are using a dynamic ip, its even worse.

Use the PHPMailer-Class and configure it to use smtp-auth along with a well configured, dedicated SMTP Server (either a local one, or a remote one) and your problems are gone.

I do not believe there is a way to do this strictly with CSS. The reason is your "important" qualifier to the question: forcing the parent element to expand with the contents of its child.

My guess is that you will have to use some bits of JavaScript to find the height of the child, and make adjustments.

So, with this HTML:

<div class="parentElement">  
  <div class="childElement">  
    ...Some Contents...  
  </div>  
</div>  

This CSS:

.parentElement {  
  position:relative;
  width:960px;
}
.childElement {
  position:absolute;
  top:50%;
  left:50%;
}

This jQuery might be useful:

$('.childElement').each(function(){
  // determine the real dimensions of the element: http://api.jquery.com/outerWidth/
  var x = $(this).outerWidth();
  var y = $(this).outerHeight();
  // adjust parent dimensions to fit child
  if($(this).parent().height() < y) {
    $(this).parent().css({height: y + 'px'});
  }
  // offset the child element using negative margins to "center" in both axes
  $(this).css({marginTop: 0-(y/2)+'px', marginLeft: 0-(x/2)+'px'});
});

Remember to load the jQ properly, either in the body below the affected elements, or in the head inside of $(document).ready(...).

I had to do 2 things: Do what Joseph Wu said and change the authentication to be SQL and Windows. But I also had to go to Server Properties > Advanced and change "Enable Contained Databases" to True.

What you're looking for is called a "reverse merge". You should consult the docs regarding the merge function in the SVN book (as luapyad, or more precisely the first commenter on that post, points out). If you're using Tortoise, you can also just go into the log view and right-click and choose "revert changes from this revision" on the one where you made the mistake.

I used the below JavaScript code and it works...

var clickButton = document.getElementById("<%= btnClearSession.ClientID %>");
clickButton.click();

I can think of three options:

Implement RFC 2217

RFC 2217 covers a com port to TCP/IP standard that allows a client on one system to emulate a serial port to the local programs, while transparently sending and receiving data and control signals to a server on another system which actually has the serial port. Here's a high-level overview.

What you would do is find or implement a client com port driver that would implement the client side of the system on your PC - appearing to be a real serial port but in reality shuttling everything to a server. You might be able to get this driver for free from Digi, Lantronix, etc in support of their real standalone serial port servers.

You would then implement the server side of the connection locally in another program - allowing the client to connect and issuing the data and control commands as needed.

It's probably non trivial, but the RFC is out there, and you might be able to find an open source project that implements one or both sides of the connection.

Modify the linux serial port driver

Alternately, the serial port driver source for Linux is readily available. Take that, gut the hardware control pieces, and have that one driver run two /dev/ttySx ports, as a simple loopback. Then connect your real program to the ttyS2 and your simulator to the other ttySx.

Use two USB<-->Serial cables in a loopback

But the easiest thing to do right now? Spend $40 on two serial port USB devices, wire them together (null modem) and actually have two real serial ports - one for the program you're testing, one for your simulator.

Better way is just to add "save action" so when you save the project it will clear the unused import's and format the code as well if you like .

Go to Window > Preferences > Java > Editor > Save Actions

and pick what ever you want .

here is my soln to define the remote and local port and then write out to a file the received data, put this all in a class of your choice with the correct imports

    static UdpClient sendClient = new UdpClient();
    static int localPort = 49999;
    static int remotePort = 49000;
    static IPEndPoint localEP = new IPEndPoint(IPAddress.Any, localPort);
    static IPEndPoint remoteEP = new IPEndPoint(IPAddress.Parse("127.0.0.1"), remotePort);
    static string logPath = System.AppDomain.CurrentDomain.BaseDirectory + "/recvd.txt";
    static System.IO.StreamWriter fw = new System.IO.StreamWriter(logPath, true);


    private static void initStuff()
    {
      
        fw.AutoFlush = true;
        sendClient.ExclusiveAddressUse = false;
        sendClient.Client.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.ReuseAddress, true);
        sendClient.Client.Bind(localEP);
        sendClient.BeginReceive(DataReceived, sendClient);
    }

    private static void DataReceived(IAsyncResult ar)
    {
        UdpClient c = (UdpClient)ar.AsyncState;
        IPEndPoint receivedIpEndPoint = new IPEndPoint(IPAddress.Any, 0);
        Byte[] receivedBytes = c.EndReceive(ar, ref receivedIpEndPoint);
        fw.WriteLine(DateTime.Now.ToString("HH:mm:ss.ff tt") +  " (" + receivedBytes.Length + " bytes)");

        c.BeginReceive(DataReceived, ar.AsyncState);
    }


    static void Main(string[] args)
    {
        initStuff();
        byte[] emptyByte = {};
        sendClient.Send(emptyByte, emptyByte.Length, remoteEP);
    }

This worked for me. Others might find it useful.

// date = 2020-08-31T00:00:00Z I'm located in Denmark (timezone is +2 hours)

So, your input is 'dan|warrior|54' and you want "warrior". You do this like so:

>>> dan = 'dan|warrior|54'
>>> dan.split('|')[1]
"warrior"

We can count from many ways for the occurrence of substring:-

public class Test1 {
public static void main(String args[]) {
    String st = "abcdsfgh yfhf hghj gjgjhbn hgkhmn abc hadslfahsd abcioh abc  a ";
    count(st, 0, "a".length());

}

public static void count(String trim, int i, int length) {
    if (trim.contains("a")) {
        trim = trim.substring(trim.indexOf("a") + length);
        count(trim, i + 1, length);
    } else {
        System.out.println(i);
    }
}

public static void countMethod2() {
    int index = 0, count = 0;
    String inputString = "mynameiskhanMYlaptopnameishclMYsirnameisjasaiwalmyfrontnameisvishal".toLowerCase();
    String subString = "my".toLowerCase();

    while (index != -1) {
        index = inputString.indexOf(subString, index);
        if (index != -1) {
            count++;
            index += subString.length();
        }
    }
    System.out.print(count);
}}

Well, I'd go with:

 Dim cmd as New SqlCommand(
 "SELECT * FROM compliance_corner"_
  + " WHERE (body LIKE @query )"_ 
  + " OR (title LIKE @query)")

 cmd.Parameters.Add("@query", "%" +searchString +"%")

I think, testing variables for values you do not expect is not a good idea in general. Because the test as your you can consider as writing a blacklist of forbidden values. But what if you forget to list all the forbidden values? Someone, even you, can crack your code with passing an unexpected value. So a more appropriate approach is something like whitelisting - testing variables only for the expected values, not unexpected. For example, if you expect the data value to be a string, instead of this:

function (data) {
  if (data != null && data !== undefined) {
    // some code here
    // but what if data === false?
    // or data === '' - empty string?
  }
}

do something like this:

function (data) {
  if (typeof data === 'string' && data.length) {
    // consume string here, it is here for sure
    // cleaner, it is obvious what type you expect
    // safer, less error prone due to implicit coercion

I am trying to avoid using VBA. But if has to be, then it has to be:)

There is quite simple UDF for you:

Function myCountIf(rng As Range, criteria) As Long
    Dim ws As Worksheet

    For Each ws In ThisWorkbook.Worksheets
        myCountIf = myCountIf + WorksheetFunction.CountIf(ws.Range(rng.Address), criteria)
    Next ws
End Function

and call it like this: =myCountIf(I:I,A13)

P.S. if you'd like to exclude some sheets, you can add If statement:

Function myCountIf(rng As Range, criteria) As Long
    Dim ws As Worksheet

    For Each ws In ThisWorkbook.Worksheets
        If ws.name <> "Sheet1" And ws.name <> "Sheet2" Then
            myCountIf = myCountIf + WorksheetFunction.CountIf(ws.Range(rng.Address), criteria)
        End If
    Next ws
End Function

UPD:

I have four "reference" sheets that I need to exclude from being scanned/searched. They are currently the last four in the workbook

Function myCountIf(rng As Range, criteria) As Long
    Dim i As Integer

    For i = 1 To ThisWorkbook.Worksheets.Count - 4
        myCountIf = myCountIf + WorksheetFunction.CountIf(ThisWorkbook.Worksheets(i).Range(rng.Address), criteria)
    Next i
End Function

Something that I saw people using is stringexpression > ''. This may be not the fastest one, but happens to be one of the shortest.

Tried it on MS SQL as well as on PostgreSQL.

I would also like to improve weston's answer for API 21 Android 5.0.

I had the same issue on my Samsung s5, when using DEFAULT font. (with the others fonts it's working fine)

I managed to make it working by setting the typeface ("sans" for example) in XML files, for each Textview or Button

<TextView
android:layout_width="match_parent"
android:layout_height="39dp"
android:textColor="@color/abs__background_holo_light"
android:textSize="12sp"
android:gravity="bottom|center"
android:typeface="sans" />

and in MyApplication Class :

public class MyApplication extends Application {
    @Override
    public void onCreate() {
    TypefaceUtil.overrideFont(getApplicationContext(), "SANS_SERIF",
    "fonts/my_font.ttf");
    }
}

Hope it helps.

Relatively straightforward solution:

1. From the first character you want to copy, hold Shift down and go all the way to the end.

2. Press Ctrl+K, which cuts the text from the file.

3. Press Ctrl+X, and then N to not save any changes.

4. Paste the cut text anywhere you want.

Alternatively, if your text fits into the screen, you can simply use mouse to select and it automatically copies it to clipboard.

Groovy is a dynamically typed language, whose syntax is very close to Java, with a number of syntax improvements that allow for lighter code and less boilerplate. It can run through an interpreter as well as being compiled, which makes it good for fast prototyping, scripts, and learning dynamic languages without having to learn a new syntax (assuming you know Java). As of Groovy 2.0, it also has growing support for static compilation. Groovy supports closures and has support for programming in a somewhat functional style, although it's still fairly far from the traditional definition of functional programming.

Clojure is a dialect of Lisp with a few advanced features like Software Transactional Memory. If you like Lisp and would like to use something like it under the JVM, Clojure is for you. It's possibly the most functional language running on the JVM, and certainly the most famous one. Also, it has a stronger emphasis on immutability than other Lisp dialects, which takes it closer to the heart of functional language enthusiasts.

Scala is a fully object oriented language, more so than Java, with one of the most advanced type systems available on non-research languages, and certainly the most advanced type system on the JVM. It also combines many concepts and features of functional languages, without compromising the object orientation, but its compromise on functional language characteristics put off some enthusiasts of the latter.

Groovy has good acceptance and a popular web framework in Grails. It also powers the Gradle build system, which is becoming a popular alternative to Maven. I personally think it is a language with limited utility, particularly as Jython and JRuby start making inroads on the JVM-land, compared to the others.

Clojure, even discounting some very interesting features, has a strong appeal just by being a Lisp dialect on JVM. It might limit its popularity, granted, but I expect it will have loyal community around it for a long time.

Scala can compete directly with Java, and give it a run for its money on almost all aspects. It can't compete in popularity at the moment, of course, and the lack of a strong corporate backing may hinder its acceptance on corporate environments. It's also a much more dynamic language than Java, in the sense of how the language evolves. From the perspective of the language, that's a good thing. From the perspective of users who plan on having thousands of lines of code written in it, not so.

As a final disclosure, I'm very familiar with Scala, and only acquainted with the other two.
