Generally I face the same problem when I copy some snippets from internet with some special chars that breaks the Intellisense.

It happened a few times with me, I discovered the problem after deleting the file and creating a new one, now when I face the same problem, fist I restart the Visual Studio, if this doesn't resolve the problem, I remove the last snippet I copied from internet and do it by hand, them the problem is gone.

Use This [Tested]

To get numeric

SELECT column1
FROM table
WHERE Isnumeric(column1) = 1; // will return Numeric values

To get non-numeric

SELECT column1
FROM table
WHERE Isnumeric(column1) = 0; // will return non-numeric values

Also you can try zenity !

user=$(zenity --entry --text 'Please enter the username:') || exit 1

I built this little fun doodad a few weeks ago. It generates funny internet images using a GA. Kinda dumb but good for a laugh.

http://www.twitterandom.info/GAFunny/

Some insight into this. It is a few mysql tables. One for the list of images and their score (which is the fitness) and another for the sub-images and their locations on the page.

Sub-images can have several details, not all implemented: +size, skew, rotation, +location, +image_url.

As people vote on how funny the image is, it is more or less likely to survive to the next generation. If it survives, it produces 5-10 offspring with slight mutations. There is no crossover yet.

If you have Excel 2007 you can write VBA to alter the connections (i.e. the external data queries) in a workbook and update the CommandText property. If you simply add ? where you want a parameter, then next time you refresh the data it'll prompt for the values for the connections! magic. When you look at the properties of the Connection the Parameters button will now be active and useable as normal.

E.g. I'd write a macro, step through it in the debugger, and make it set the CommandText appropriately. Once you've done this you can remove the macro - it's just a means to update the query.

Sub UpdateQuery
    Dim cn As WorkbookConnection
    Dim odbcCn As ODBCConnection, oledbCn As OLEDBConnection
    For Each cn In ThisWorkbook.Connections
        If cn.Type = xlConnectionTypeODBC Then
            Set odbcCn = cn.ODBCConnection

            ' If you do have multiple connections you would want to modify  
            ' the line below each time you run through the loop.
            odbcCn.CommandText = "select blah from someTable where blah like ?"

        ElseIf cn.Type = xlConnectionTypeOLEDB Then
            Set oledbCn = cn.OLEDBConnection
            oledbCn.CommandText = "select blah from someTable where blah like ?" 
        End If
    Next
End Sub

I agree with Matthew Flaschen's answer and just wanted to show examples of the options for the case you cannot switch to List (because a library returns you a Collection):

List list = new ArrayList(theCollection);
list.get(5);

Or

Object[] list2 = theCollection.toArray();
doSomethingWith(list[2]);

If you know what generics is I can provide samples for that too.

Edit: It's another question what the intent and semantics of the original collection is.

The <h:outputLink> renders a fullworthy HTML <a> element with the proper URL in the href attribute which fires a bookmarkable GET request. It cannot directly invoke a managed bean action method.

<h:outputLink value="destination.xhtml">link text</h:outputLink>

The <h:commandLink> renders a HTML <a> element with an onclick script which submits a (hidden) POST form and can invoke a managed bean action method. It's also required to be placed inside a <h:form>.

<h:form>
    <h:commandLink value="link text" action="destination" />
</h:form>

The ?faces-redirect=true parameter on the <h:commandLink>, which triggers a redirect after the POST (as per the Post-Redirect-Get pattern), only improves bookmarkability of the target page when the link is actually clicked (the URL won't be "one behind" anymore), but it doesn't change the href of the <a> element to be a fullworthy URL. It still remains #.

<h:form>
    <h:commandLink value="link text" action="destination?faces-redirect=true" />
</h:form>

Since JSF 2.0, there's also the <h:link> which can take a view ID (a navigation case outcome) instead of an URL. It will generate a HTML <a> element as well with the proper URL in href.

<h:link value="link text" outcome="destination" />

So, if it's for pure and bookmarkable page-to-page navigation like the SO username link, then use <h:outputLink> or <h:link>. That's also better for SEO since bots usually doesn't cipher POST forms nor JS code. Also, UX will be improved as the pages are now bookmarkable and the URL is not "one behind" anymore.

When necessary, you can do the preprocessing job in the constructor or @PostConstruct of a @RequestScoped or @ViewScoped @ManagedBean which is attached to the destination page in question. You can make use of @ManagedProperty or <f:viewParam> to set GET parameters as bean properties.

• What can <f:metadata>, <f:viewParam> and <f:viewAction> be used for?

B+ Trees are especially good in block-based storage (eg: hard disk). with this in mind, you get several advantages, for example (from the top of my head):

• high fanout / low depth: that means you have to get less blocks to get to the data. with data intermingled with the pointers, each read gets less pointers, so you need more seeks to get to the data

• simple and consistent block storage: an inner node has N pointers, nothing else, a leaf node has data, nothing else. that makes it easy to parse, debug and even reconstruct.

• high key density means the top nodes are almost certainly on cache, in many cases all inner nodes get quickly cached, so only the data access has to go to disk.

Use function Number();

$(function() {_x000D_
_x000D_
  var price1 = 1000;_x000D_
  var price2 = 500000;_x000D_
  var price3 = 15245000;_x000D_
_x000D_
  $("span#s1").html(Number(price1).toLocaleString('en'));_x000D_
  $("span#s2").html(Number(price2).toLocaleString('en'));_x000D_
  $("span#s3").html(Number(price3).toLocaleString('en'));_x000D_
_x000D_
  console.log(Number(price).toLocaleString('en'));_x000D_
_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>_x000D_

This problem arises when you have composer installed locally. To make it globally executable,run the below command in terminal

sudo mv composer.phar /usr/local/bin/composer

For CentOS 7 the command is

sudo mv composer.phar /usr/bin/composer

You can do something like this:

var newList = list.Where(w => w.Name == "height")
              .Select(s => new {s.Name, s.Value= 30 }).ToList();

But I would rather choose to use foreach because LINQ is for querying while you want to edit the data.

If you have some params, you can do this.

    $results = DB::table('rooms')
    ->distinct()
    ->leftJoin('bookings', function($join) use ($param1, $param2)
    {
        $join->on('rooms.id', '=', 'bookings.room_type_id');
        $join->on('arrival','=',DB::raw("'".$param1."'"));
        $join->on('arrival','=',DB::raw("'".$param2."'"));

    })
    ->where('bookings.room_type_id', '=', NULL)
    ->get();

and then return your query

return $results;

In addition to all the options listed by other answers, you can use git reset with the Git object (hash, branch, HEAD~x, tag, ...) of interest and the path of your file:

git reset <hash> /path/to/file

In your example:

git reset 27cf8e8 my_file.txt

What this does is that it will revert my_file.txt to its version at the commit 27cf8e8 in the index while leaving it untouched (so in its current version) in the working directory.

From there, things are very easy:

• you can compare the two versions of your file with git diff --cached my_file.txt
• you can get rid of the old version of the file with git restore --staged file.txt (or, prior to Git v2.23, git reset file.txt) if you decide that you don't like it
• you can restore the old version with git commit -m "Restore version of file.txt from 27cf8e8" and git restore file.txt (or, prior to Git v2.23, git checkout -- file.txt)
• you can add updates from the old to the new version only for some hunks by running git add -p file.txt (then git commit and git restore file.txt).

Lastly, you can even interactively pick and choose which hunk(s) to reset in the very first step if you run:

git reset -p 27cf8e8 my_file.txt

So git reset with a path gives you lots of flexibility to retrieve a specific version of a file to compare with its currently checked-out version and, if you choose to do so, to revert fully or only for some hunks to that version.

Edit: I just realized that I am not answering your question since what you wanted wasn't a diff or an easy way to retrieve part or all of the old version but simply to cat that version.

Of course, you can still do that after resetting the file with:

git show :file.txt

to output to standard output or

git show :file.txt > file_at_27cf8e8.txt

But if this was all you wanted, running git show directly with git show 27cf8e8:file.txt as others suggested is of course much more direct.

I am going to leave this answer though because running git show directly allows you to get that old version instantly, but if you want to do something with it, it isn't nearly as convenient to do so from there as it is if you reset that version in the index.

To tell eclipse to use JDK, you have to follow the below steps.

1. Select the Window menu and then Select Preferences. You can see a dialog box.
2. Then select Java ---> Installed JRE’s
3. Then click Add and select Standard VM then click Next
4. In the JRE home, navigate to the folder you’ve installed the JDK (For example, in my system my JDK was in C:\Program Files\Java\jdk1.8.0_181\ )
5. Now click on Finish.

After completing the above steps, you are done now and eclipse will start using the selected JDK for compilation.

you could try

$('*').not('#div').bind('touchmove', false);

add this if necessary

$('#div').bind('touchmove');

note that everything is fixed except #div

Try this

git clone ssh://[email protected]:11111/home/git/repo.git

public void sampleConnection() throws Exception {

     Configuration cfg = new Configuration().addResource("hibernate.cfg.xml").configure();
     StandardServiceRegistryBuilder ssrb = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties());
     SessionFactory sessionFactory = configuration.buildSessionFactory(ssrb.build());
     Session session = sessionFactory.openSession();
     logger.debug(" connection with the database created successfuly.");
}

If you're using data binding, then you need to use the ContentRendered event.

For the code below, the Header is NULL when the Loaded event is raised. However, Header gets its value when the ContentRendered event is raised.

<MenuItem Header="{Binding NewGame_Name}" Command="{Binding NewGameCommand}" />

Are you asking for renaming column itself or capitalise the data inside column? If its data you've to change, then use this:

UPDATE [yourtable]
SET word=UPPER(LEFT(word,1))+LOWER(SUBSTRING(word,2,LEN(word)))

If you just wanted to change it only for displaying and do not need the actual data in table to change:

SELECT UPPER(LEFT(word,1))+LOWER(SUBSTRING(word,2,LEN(word))) FROM [yourtable]

Hope this helps.

EDIT: I realised about the '-' so here is my attempt to solve this problem in a function.

CREATE FUNCTION [dbo].[CapitalizeFirstLetter]
(
--string need to format
@string VARCHAR(200)--increase the variable size depending on your needs.
)
RETURNS VARCHAR(200)
AS

BEGIN
--Declare Variables
DECLARE @Index INT,
@ResultString VARCHAR(200)--result string size should equal to the @string variable size
--Initialize the variables
SET @Index = 1
SET @ResultString = ''
--Run the Loop until END of the string

WHILE (@Index <LEN(@string)+1)
BEGIN
IF (@Index = 1)--first letter of the string
BEGIN
--make the first letter capital
SET @ResultString =
@ResultString + UPPER(SUBSTRING(@string, @Index, 1))
SET @Index = @Index+ 1--increase the index
END

-- IF the previous character is space or '-' or next character is '-'

ELSE IF ((SUBSTRING(@string, @Index-1, 1) =' 'or SUBSTRING(@string, @Index-1, 1) ='-' or SUBSTRING(@string, @Index+1, 1) ='-') and @Index+1 <> LEN(@string))
BEGIN
--make the letter capital
SET
@ResultString = @ResultString + UPPER(SUBSTRING(@string,@Index, 1))
SET
@Index = @Index +1--increase the index
END
ELSE-- all others
BEGIN
-- make the letter simple
SET
@ResultString = @ResultString + LOWER(SUBSTRING(@string,@Index, 1))
SET
@Index = @Index +1--incerase the index
END
END--END of the loop

IF (@@ERROR
<> 0)-- any error occur return the sEND string
BEGIN
SET
@ResultString = @string
END
-- IF no error found return the new string
RETURN @ResultString
END

So then the code would be:

UPDATE [yourtable]
SET word=dbo.CapitalizeFirstLetter([STRING TO GO HERE])

My preference is to utilize the inline attribute. This will cause the icon to correctly scale with the size of the button.

    <button mat-button>
      <mat-icon inline=true>local_movies</mat-icon>
      Movies
    </button>

    <!-- Link button -->
    <a mat-flat-button color="accent" routerLink="/create"><mat-icon inline=true>add</mat-icon> Create</a>

I add this to my styles.css to:

• solve the vertical alignment problem of the icon inside the button
• material icon fonts are always a little too small compared to button text

button.mat-button .mat-icon,
a.mat-button .mat-icon,
a.mat-raised-button .mat-icon,
a.mat-flat-button .mat-icon,
a.mat-stroked-button .mat-icon {
  vertical-align: top;
  font-size: 1.25em;
}

The hold on feature is switched on by default in matplotlib.pyplot. So each time you evoke plt.plot() before plt.show() a drawing is added to the plot. Launching plt.plot() after the function plt.show() leads to redrawing the whole picture.

You need text() or html() for label not val() The function should not be called for label instead it is used to get values of input like text or checkbox etc.

Change

value = $("#telefon").val(); 

To

value = $("#telefon").text(); 

Perhaps 0 or '\u0000' would do?

Previous responses didn't work with my problem. It was only in production, with tomcat and apache mod_proxy_ajp. Post body lost non ascii chars by ? The problem finally was with JVM defaultCharset (US-ASCII in a default instalation: Charset dfset = Charset.defaultCharset();) so, the solution was run tomcat server with a modifier to run the JVM with UTF-8 as default charset:

JAVA_OPTS="$JAVA_OPTS -Dfile.encoding=UTF-8" 

(add this line to catalina.sh and service tomcat restart)

Maybe you must also change linux system variable (edit ~/.bashrc and ~/.profile for permanent change, see https://perlgeek.de/en/article/set-up-a-clean-utf8-environment)

First off, RangeToHTML. The script calls it like a method, but it isn't. It's a popular function by MVP Ron de Bruin. Coincidentally, that links points to the exact source of the script you posted, before those few lines got b?u?t?c?h?e?r?e?d? modified.

On with Range.SpecialCells. This method operates on a range and returns only those cells that match the given criteria. In your case, you seem to be only interested in the visible text cells. Importantly, it operates on a Range, not on HTML text.

For completeness sake, I'll post a working version of the script below. I'd certainly advise to disregard it and revisit the excellent original by Ron the Bruin.

Since you already have sent some data,

System.out.println("going to demo.jsp");

you won't be able to send a redirect.

You can use this javascript plugin

It can get a large list of information for you about mobiles and desktop machines including the uuid for example

var uuid = new DeviceUUID().get();

this works for me. You still get the errors but they're easy enough to suppress. it also works from within subfolders!

You can put this in an if then statement if you need to conditionally do more.

In my case there were two jQuery's, for the inner and outer HTML. I had four steps before I could attach inner events:

1. wait for outer jQuery to be ready
2. wait for iframe to load
3. grab inner jQuery
4. wait for inner jQuery to be ready

$(function() {   // 1. wait for the outer jQuery to be ready, aka $(document).ready
    $('iframe#filecontainer').on('load', function() {   // 2. wait for the iframe to load
        var $inner$ = $(this)[0].contentWindow.$;   // 3. get hold of the inner jQuery
        $inner$(function() {   // 4. wait for the inner jQuery to be ready
            $inner$.on('click', function () {   // Now I can intercept inner events.
                // do something
            });
        });
    });
});

The trick is to use the inner jQuery to attach events. Notice how I'm getting the inner jQuery:

        var $inner$ = $(this)[0].contentWindow.$;

I had to bust out of jQuery into the object model for it. The $('iframe').contents() approach in the other answers didn't work in my case because that stays with the outer jQuery. (And by the way returns contentDocument.)

First check path Specified for User Settings file: in Settings -> Build,Execution,Development -> Build Tools -> Maven . The field should have path of the settings.xml of your maven. Also the settings.xml should have correct path of remote repository.

One way to do this is with a delegate

List<cTag> week = new List<cTag>();
// add some stuff to the list
// now sort
week.Sort(delegate(cTag c1, cTag c2) { return c1.date.CompareTo(c2.date); });

Another way (Using Formulas in VBA). I guess this is the shortest VBA code as well?

Sub Sample()
    Dim ws As Worksheet
    Dim lRow As Long

    Set ws = ThisWorkbook.Sheets("Sheet1")

    With ws
        lRow = .Range("A" & .Rows.Count).End(xlUp).Row

        .Range("B1:B" & lRow).Formula = "=If(A1<>"""",""My Text"","""")"
        .Range("B1:B" & lRow).Value = .Range("B1:B" & lRow).Value
    End With
End Sub

You can use np.where to match the boolean conditions corresponding to Nan values of the array and map each outcome to generate a list of tuples.

ASCII has 128 code positions, allocated to graphic characters and control characters (control codes).

Unicode has 1,114,112 code positions. About 100,000 of them have currently been allocated to characters, and many code points have been made permanently noncharacters (i.e. not used to encode any character ever), and most code points are not yet assigned.

The only things that ASCII and Unicode have in common are: 1) They are character codes. 2) The 128 first code positions of Unicode have been defined to have the same meanings as in ASCII, except that the code positions of ASCII control characters are just defined as denoting control characters, with names corresponding to their ASCII names, but their meanings are not defined in Unicode.

Sometimes, however, Unicode is characterized (even in the Unicode standard!) as “wide ASCII”. This is a slogan that mainly tries to convey the idea that Unicode is meant to be a universal character code the same way as ASCII once was (though the character repertoire of ASCII was hopelessly insufficient for universal use), as opposite to using different codes in different systems and applications and for different languages.

Unicode as such defines only the “logical size” of characters: Each character has a code number in a specific range. These code numbers can be presented using different transfer encodings, and internally, in memory, Unicode characters are usually represented using one or two 16-bit quantities per character, depending on character range, sometimes using one 32-bit quantity per character.

An expression like this:

[a-zA-Z]*[0-9\+\*][a-zA-Z0-9\+\*]*

should work just fine (obviously insert any additional special characters you want to allow or use ^ operator to match anything except letters/numbers); no need to use complicated lookarounds. This approach makes sense if you only want to allow a certain subset of special characters that you know are "safe", and disallow all others.

If you want to include all special characters except certain ones which you know are "unsafe", then it makes sense to use something like:

\w[^\\]*[^a-zA-Z\\][^\\]*

In this case, you are explicitly disallowing backslashes in your password and allowing any combination with at least one non-alphabetic character otherwise.

The expression above will match any string containing letters and at least one number or +,*. As for the "length of 8" requirement, theres really no reason to check that using regex.

This will give you what you want:

eg2011cleaned <- eg2011[!eg2011$ID %in% bg2011missingFromBeg, ]

The error in your second attempt is because you forgot the ,

In general, for convenience, the specification object[index] subsets columns for a 2d object. If you want to subset rows and keep all columns you have to use the specification object[index_rows, index_columns], while index_cols can be left blank, which will use all columns by default.

However, you still need to include the , to indicate that you want to get a subset of rows instead of a subset of columns.

Note that there's some confusion about location of the autocomplete attribute. It can be applied either to the whole FORM tag or to individual INPUT tags, and this wasn't really standardized before HTML5 (that explicitly allows both locations). Older docs most notably this Mozilla article only mentions FORM tag. At the same time some security scanners will only look for autocomplete in INPUT tag and complain if it's missing (even if it is in the parent FORM). A more detailed analysis of this mess is posted here: Confusion over AUTOCOMPLETE=OFF attributes in HTML forms.

Part 3 - Tricks and Efficient Code

MySQL in() efficiency

I thought I would add some extra bits, for tips and tricks that have come up.

One question I see come up a fair bit, is How do I get non-matching rows from two tables and I see the answer most commonly accepted as something like the following (based on our cars and brands table - which has Holden listed as a brand, but does not appear in the cars table):

select
    a.ID,
    a.brand
from
    brands a
where
    a.ID not in(select brand from cars)

And yes it will work.

+----+--------+
| ID | brand  |
+----+--------+
|  6 | Holden |
+----+--------+
1 row in set (0.00 sec)

However it is not efficient in some database. Here is a link to a Stack Overflow question asking about it, and here is an excellent in depth article if you want to get into the nitty gritty.

The short answer is, if the optimiser doesn't handle it efficiently, it may be much better to use a query like the following to get non matched rows:

select
    a.brand
from
    brands a
        left join cars b
            on a.id=b.brand
where
    b.brand is null

+--------+
| brand  |
+--------+
| Holden |
+--------+
1 row in set (0.00 sec)

Update Table with same table in subquery

Ahhh, another oldie but goodie - the old You can't specify target table 'brands' for update in FROM clause.

MySQL will not allow you to run an update... query with a subselect on the same table. Now, you might be thinking, why not just slap it into the where clause right? But what if you want to update only the row with the max() date amoung a bunch of other rows? You can't exactly do that in a where clause.

update 
    brands 
set 
    brand='Holden' 
where 
    id=
        (select 
            id 
        from 
            brands 
        where 
            id=6);
ERROR 1093 (HY000): You can't specify target table 'brands' 
for update in FROM clause

So, we can't do that eh? Well, not exactly. There is a sneaky workaround that a surprisingly large number of users don't know about - though it does include some hackery that you will need to pay attention to.

You can stick the subquery within another subquery, which puts enough of a gap between the two queries so that it will work. However, note that it might be safest to stick the query within a transaction - this will prevent any other changes being made to the tables while the query is running.

update 
    brands 
set 
    brand='Holden' 
where id=
    (select 
        id 
    from 
        (select 
            id 
        from 
            brands 
        where 
            id=6
        ) 
    as updateTable);

Query OK, 0 rows affected (0.02 sec)
Rows matched: 1  Changed: 0  Warnings: 0

I realize I am a little late here, (5 years or so), but I think there is a better answer than the accepted one as follows:

$("#addComment").click(function() {
    if(typeof TinyMCE === "undefined") {
        $.ajax({
            url: "tinymce.js",
            dataType: "script",
            cache: true,
            success: function() {
                TinyMCE.init();
            }
        });
    }
});

The getScript() function actually prevents browser caching. If you run a trace you will see the script is loaded with a URL that includes a timestamp parameter:

http://www.yoursite.com/js/tinymce.js?_=1399055841840

If a user clicks the #addComment link multiple times, tinymce.js will be re-loaded from a differently timestampped URL. This defeats the purpose of browser caching.

===

Alternatively, in the getScript() documentation there is a some sample code that demonstrates how to enable caching by creating a custom cachedScript() function as follows:

jQuery.cachedScript = function( url, options ) {

    // Allow user to set any option except for dataType, cache, and url
    options = $.extend( options || {}, {
        dataType: "script",
        cache: true,
        url: url
    });

    // Use $.ajax() since it is more flexible than $.getScript
    // Return the jqXHR object so we can chain callbacks
    return jQuery.ajax( options );
};

// Usage
$.cachedScript( "ajax/test.js" ).done(function( script, textStatus ) {
    console.log( textStatus );
});

===

Or, if you want to disable caching globally, you can do so using ajaxSetup() as follows:

$.ajaxSetup({
    cache: true
});

Ctrl + K + D (Entire document)

Ctrl + K + F (Selection only)

It is working, but it wont modify the caller object, but returning a new String.
So you just need to assign it to a new String variable, or to itself:

string = string.replace("to", "xyz");

or

String newString = string.replace("to", "xyz");

API Docs

public String replace (CharSequence target, CharSequence replacement) 

Since: API Level 1

Copies this string replacing occurrences of the specified target sequence with another sequence. The string is processed from the beginning to the end.

Parameters

• target the sequence to replace.
• replacement the replacement sequence.

Returns the resulting string.
Throws NullPointerException if target or replacement is null.

Using this answer from Asya Kamsky, I wrote a one-line bat script for Windows. The line looks like this:

mongo --quiet %1 --eval "printjson(db.%2.find().toArray())" > output.json

Then one can run it:

exportToJson.bat DbName CollectionName

See section 5.1:

http://docs.python.org/library/stdtypes.html

Any object can be tested for truth value, for use in an if or while condition or as operand of the Boolean operations below. The following values are considered false:

None

False

zero of any numeric type, for example, 0, 0L, 0.0, 0j.

any empty sequence, for example, '', (), [].

any empty mapping, for example, {}.

instances of user-defined classes, if the class defines a __nonzero__() or __len__() method, when that method returns the integer zero or bool value False. [1]

All other values are considered true — so objects of many types are always true.

Operations and built-in functions that have a Boolean result always return 0 or False for false and 1 or True for true, unless otherwise stated. (Important exception: the Boolean operations or and and always return one of their operands.)

You could try the subplot_tool()

plt.subplot_tool()

This is based on the assumption that you're getting an error about the date format, such as an invalid month value or non-numeric character when numeric expected.

Dates stored in the database do not have formats. When you query the date your client is formatting the date for display, as 4/16/2011. Normally the same date format is used for selecting and updating dates, but in this case they appear to be different - so your client is apparently doing something more complicated that SQL*Plus, for example.

When you try to update it it's using a default date format model. Because of how it's displayed you're assuming that is MM/DD/YYYY, but it seems not to be. You could find out what it is, but it's better not to rely on the default or any implicit format models at all.

Whether that is the problem or not, you should always specify the date model:

UPDATE PASOFDATE SET ASOFDATE = TO_DATE('11/21/2012', 'MM/DD/YYYY');

Since you aren't specifying a time component - all Oracle DATE columns include a time, even if it's midnight - you could also use a date literal:

UPDATE PASOFDATE SET ASOFDATE = DATE '2012-11-21';

You should maybe check that the current value doesn't include a time, though the column name suggests it doesn't.

You can using dict , fillna with different value for different column

df.fillna({'a':0,'b':0})
Out[829]: 
     a    b    c
0  1.0  4.0  NaN
1  2.0  5.0  NaN
2  3.0  0.0  7.0
3  0.0  6.0  8.0

After assign it back

df=df.fillna({'a':0,'b':0})
df
Out[831]: 
     a    b    c
0  1.0  4.0  NaN
1  2.0  5.0  NaN
2  3.0  0.0  7.0
3  0.0  6.0  8.0

To match the title of this question, the value of the id attribute is:

var myId = $(this).attr('id');
alert( myId );

BUT, of course, the element must already have the id element defined, as:

<option id="opt7" class='select_continent' value='7'>Antarctica</option>

In the OP post, this was not the case.

IMPORTANT:

Note that plain js is faster (in this case):

var myId = this.id
alert(  myId  );

That is, if you are just storing the returned text into a variable as in the above example. No need for jQuery's wonderfulness here.

The issue with

List<String> list = new LinkedList();

is that on the left hand side, you are using the generic type List<String> where on the right side you are using the raw type LinkedList. Raw types in Java effectively only exist for compatibility with pre-generics code and should never be used in new code unless you absolutely have to.

Now, if Java had generics from the beginning and didn't have types, such as LinkedList, that were originally created before it had generics, it probably could have made it so that the constructor for a generic type automatically infers its type parameters from the left-hand side of the assignment if possible. But it didn't, and it must treat raw types and generic types differently for backwards compatibility. That leaves them needing to make a slightly different, but equally convenient, way of declaring a new instance of a generic object without having to repeat its type parameters... the diamond operator.

As far as your original example of List<String> list = new LinkedList(), the compiler generates a warning for that assignment because it must. Consider this:

List<String> strings = ... // some list that contains some strings

// Totally legal since you used the raw type and lost all type checking!
List<Integer> integers = new LinkedList(strings);

Generics exist to provide compile-time protection against doing the wrong thing. In the above example, using the raw type means you don't get this protection and will get an error at runtime. This is why you should not use raw types.

// Not legal since the right side is actually generic!
List<Integer> integers = new LinkedList<>(strings);

The diamond operator, however, allows the right hand side of the assignment to be defined as a true generic instance with the same type parameters as the left side... without having to type those parameters again. It allows you to keep the safety of generics with almost the same effort as using the raw type.

I think the key thing to understand is that raw types (with no <>) cannot be treated the same as generic types. When you declare a raw type, you get none of the benefits and type checking of generics. You also have to keep in mind that generics are a general purpose part of the Java language... they don't just apply to the no-arg constructors of Collections!

find_elements_by_xpath("//*[@class='class name']")

is a great solution

When your include paths are different

Linker errors can happen when a header file and its associated shared library (.lib file) go out of sync. Let me explain.

How do linkers work? The linker matches a function declaration (declared in the header) with its definition (in the shared library) by comparing their signatures. You can get a linker error if the linker doesn't find a function definition that matches perfectly.

Is it possible to still get a linker error even though the declaration and the definition seem to match? Yes! They might look the same in source code, but it really depends on what the compiler sees. Essentially you could end up with a situation like this:

// header1.h
typedef int Number;
void foo(Number);

// header2.h
typedef float Number;
void foo(Number); // this only looks the same lexically

Note how even though both the function declarations look identical in source code, but they are really different according to the compiler.

You might ask how one ends up in a situation like that? Include paths of course! If when compiling the shared library, the include path leads to header1.h and you end up using header2.h in your own program, you'll be left scratching your header wondering what happened (pun intended).

An example of how this can happen in the real world is explained below.

Further elaboration with an example

I have two projects: graphics.lib and main.exe. Both projects depend on common_math.h. Suppose the library exports the following function:

// graphics.lib    
#include "common_math.h" 
   
void draw(vec3 p) { ... } // vec3 comes from common_math.h

And then you go ahead and include the library in your own project.

// main.exe
#include "other/common_math.h"
#include "graphics.h"

int main() {
    draw(...);
}

Boom! You get a linker error and you have no idea why it's failing. The reason is that the common library uses different versions of the same include common_math.h (I have made it obvious here in the example by including a different path, but it might not always be so obvious. Maybe the include path is different in the compiler settings).

Note in this example, the linker would tell you it couldn't find draw(), when in reality you know it obviously is being exported by the library. You could spend hours scratching your head wondering what went wrong. The thing is, the linker sees a different signature because the parameter types are slightly different. In the example, vec3 is a different type in both projects as far as the compiler is concerned. This could happen because they come from two slightly different include files (maybe the include files come from two different versions of the library).

Debugging the linker

DUMPBIN is your friend, if you are using Visual Studio. I'm sure other compilers have other similar tools.

The process goes like this:

1. Note the weird mangled name given in the linker error. (eg. draw@graphics@XYZ).
2. Dump the exported symbols from the library into a text file.
3. Search for the exported symbol of interest, and notice that the mangled name is different.
4. Pay attention to why the mangled names ended up different. You would be able to see that the parameter types are different, even though they look the same in the source code.
5. Reason why they are different. In the example given above, they are different because of different include files.

[1] By project I mean a set of source files that are linked together to produce either a library or an executable.

That's because the byte[] output is well, and array of bytes, you may think on it as an array of bytes representing each one an integer, but when you add them all into a single string you get something that is NOT an integer, that's why. You may either have it as an array of integers or try to create an instance of BigInteger.

Manually creating a folder named 'npm' in the displayed path fixed the problem.

To set timeout on a per page level, you could use this simple code:

Page.Server.ScriptTimeout = 60;

Note: 60 means 60 seconds, this time-out applies only if the debug attribute in the compilation element is False.

Simply add the eventhandler to the button when creating it.

 button.Click += new EventHandler(this.button_Click);

void button_Click(object sender, System.EventArgs e)

Potentially for a different question, but I'm providing my version of @Alvero's answer (using unidecode). I want to do a "regular" strip on my strings, i.e. the beginning and end of my string for whitespace characters, and then replace only other whitespace characters with a "regular" space, i.e.

"Ceñía?mañana????"

to

"Ceñía mañana"

,

def safely_stripped(s: str):
    return ' '.join(
        stripped for stripped in
        (bit.strip() for bit in
         ''.join((c if unidecode(c) else ' ') for c in s).strip().split())
        if stripped)

We first replace all non-unicode spaces with a regular space (and join it back again),

''.join((c if unidecode(c) else ' ') for c in s)

And then we split that again, with python's normal split, and strip each "bit",

(bit.strip() for bit in s.split())

And lastly join those back again, but only if the string passes an if test,

' '.join(stripped for stripped in s if stripped)

And with that, safely_stripped('????Ceñía?mañana????') correctly returns 'Ceñía mañana'.

Here is the code that worked for me:

public ArrayList GetBBGroups(WindowsIdentity identity)
{
    ArrayList groups = new ArrayList();

    try
    {
        String userName = identity.Name;
        int pos = userName.IndexOf(@"\");
        if (pos > 0) userName = userName.Substring(pos + 1);

        PrincipalContext domain = new PrincipalContext(ContextType.Domain, "riomc.com");
        UserPrincipal user = UserPrincipal.FindByIdentity(domain, IdentityType.SamAccountName, userName);

        DirectoryEntry de = new DirectoryEntry("LDAP://RIOMC.com");
        DirectorySearcher search = new DirectorySearcher(de);
        search.Filter = "(&(objectClass=group)(member=" + user.DistinguishedName + "))";
        search.PropertiesToLoad.Add("samaccountname");
        search.PropertiesToLoad.Add("cn");

        String name;
        SearchResultCollection results = search.FindAll();
        foreach (SearchResult result in results)
        {
            name = (String)result.Properties["samaccountname"][0];
            if (String.IsNullOrEmpty(name))
            {
                name = (String)result.Properties["cn"][0];
            }
            GetGroupsRecursive(groups, de, name);
        }
    }
    catch
    {
        // return an empty list...
    }

    return groups;
}

public void GetGroupsRecursive(ArrayList groups, DirectoryEntry de, String dn)
{
    DirectorySearcher search = new DirectorySearcher(de);
    search.Filter = "(&(objectClass=group)(|(samaccountname=" + dn + ")(cn=" + dn + ")))";
    search.PropertiesToLoad.Add("memberof");

    String group, name;
    SearchResult result = search.FindOne();
    if (result == null) return;

    group = @"RIOMC\" + dn;
    if (!groups.Contains(group))
    {
        groups.Add(group);
    }
    if (result.Properties["memberof"].Count == 0) return;
    int equalsIndex, commaIndex;
    foreach (String dn1 in result.Properties["memberof"])
    {
        equalsIndex = dn1.IndexOf("=", 1);
        if (equalsIndex > 0)
        {
            commaIndex = dn1.IndexOf(",", equalsIndex + 1);
            name = dn1.Substring(equalsIndex + 1, commaIndex - equalsIndex - 1);
            GetGroupsRecursive(groups, de, name);
        }
    }
}

I measured it's performance in a loop of 200 runs against the code that uses the AttributeValuesMultiString recursive method; and it worked 1.3 times faster. It might be so because of our AD settings. Both snippets gave the same result though.

I agree with tnguyen80's response. Please note that when there is a specific string value in query better to given entire query in double quotes.

For example:

$hive -e "select * from table where city = 'London' and id >=100" > /home/user/outputdirectory/city details.csv

Despite that my server was running, I had the same problem. I found out that it was the port. So you need to specify the port:

mysql -u user -p --port 0000

The port on your machine may be different. To find out on which port mysql is running open the mysql ini file and look for port=. A port often used is 3306.

Example how to log on to mysql

mysql -u root -p --port 3306 

As per W3C spec,

The list properties ... do not allow authors to specify distinct style (colors, fonts, alignment, etc.) for the list marker ...

But the idea with a span inside the list above should work fine!

Yes, JavaScript variables will exist in the scope they are created.

var bannerID = 55;

<input id="EditBanner" type="button" 
  value="Edit Image" onclick="EditBanner(bannerID);"/>


function EditBanner(id) {
   //Do something with id
}

If you use event handlers and jQuery it is simple also

$("#EditBanner").click(function() {
   EditBanner(bannerID);
});

df.columnname[1].split('.', 1)

This will split data with the first occurrence of '.' in the string or data frame column value.

I suspect you need a more general answer:

There are no rules on casting pointers in C! The language lets you cast any pointer to any other pointer without comment.

But the thing is: There is no data conversion or whatever done! Its solely your own responsibilty that the system does not misinterpret the data after the cast - which would generally be the case, leading to runtime error.

So when casting its totally up to you to take care that if data is used from a casted pointer the data is compatible!

C is optimized for performance, so it lacks runtime reflexivity of pointers/references. But that has a price - you as a programmer have to take better care of what you are doing. You have to know on your self if what you want to do is "legal"

How does the server know that it should pull image.png from the /pictures folder when you visit the website and browse to the /system/files/images folder in your web browser? A so-called symbolic link is the guy that is responsible for this behavior. Somewhere in your system, there is a symlink that tells your server "If a visitor requests /system/files/images/image.png then show him /pictures/image.png."

And what is the role of the FollowSymLinks setting in this?

FollowSymLinks relates to server security. When dealing with web servers, you can't just leave things undefined. You have to tell who has access to what. The FollowSymLinks setting tells your server whether it should or should not follow symlinks. In other words, if FollowSymLinks was disabled in our case, browsing to the /system/files/images/image.png file would return depending on other settings either the 403 (access forbidden) or 404 (not found) error.

401 means "Unauthorized", so there must be something with your credentials.

I think that java URL does not support the syntax you are showing. You could use an Authenticator instead.

Authenticator.setDefault(new Authenticator() {

    @Override
    protected PasswordAuthentication getPasswordAuthentication() {          
        return new PasswordAuthentication(login, password.toCharArray());
    }
});

and then simply invoking the regular url, without the credentials.

The other option is to provide the credentials in a Header:

String loginPassword = login+ ":" + password;
String encoded = new sun.misc.BASE64Encoder().encode (loginPassword.getBytes());
URLConnection conn = url.openConnection();
conn.setRequestProperty ("Authorization", "Basic " + encoded);

PS: It is not recommended to use that Base64Encoder but this is only to show a quick solution. If you want to keep that solution, look for a library that does. There are plenty.

In case you have two-factor authentication enabled, make sure that you create a new access token and not regenerate an old one.

That didn't seem to work in my case.

These instructions work for OSX High Sierra and avoid running gdb as root (yuck!). I recently updated from OSX 10.13.2 to 10.3.3. I think this is when gdb 8.0.1 (installed w/ homebrew) started failing for me.

I had difficulty with other people's instructions. After different instructions, everything was a mess. So I started a fresh. I more or less followed these instructions.

Clean the mess :

1. brew uninstall --force gdb # This deletes _all_ versions of gdb on the machine
2. In Applications -> Utilities -> Keychain Access, I deleted all previous gdb certificates and keys (be sure you know what you're doing here!). It's unclear if this is necessary, but since I'd buggered up trying to create those certificates and keys using other instructions I eliminated them anyways. I had keys and certificates in both login and system.

Now reinstall gdb.

3. brew install gdb
4. Within Keychain Access, go to menu Keychain Access-> Certificate Assistant -> Create a Certificate
5. Check "Let me override defaults" and set

Name : gdb-cert
Identity Type: Self Signed Root
Certificate Type : Code Signing

[X] Let me override defaults

6. On 1st Certificate Information page:

Serial Number : 1
Validity Period (days): 3650

7. On 2nd Certificate Information page, I left all fields blank except those already filled in.

8. On Key Pair Information page, I left the defaults

Key Size : 2048
Algorithm : RSA

9. On Key Usage Extension page, I left the defaults checked.

[X] Include Key Usage Extension
[X] This extension is critical
Capabilities:
[X] Signature

10. On Extended Key Usage Extension page, I left the defaults checked.

[X] Include Extended Key Usage Extension
[X] This extension is critical
Capabilities:
[X] Code Signing

11. On Basic Constraints Extension Page, nothing was checked (default).

12. On Subject Alternate Name Extension page, I left the default checked and didn't add anything else.

[X] Include Subject Alternate Name Extension

13. On Specify a Location for the certificate page, I set

Keychain: System

14. I clicked Create and was prompted for my password.

15. Back in the Keychain Access app, I went to System and right clicked on gdb-cert and under dropdown menu Trust, I changed all the fields to Always Trust.

16. Rebooted computer.

17. At the Terminal, I ran codesign -s gdb-cert /usr/local/bin/gdb. I entered my password when prompted.

18. At the Terminal, I ran echo "set startup-with-shell off" >> ~/.gdbinit

19. I ran gdb myprogram and then start within the gdb console. Here, I believe, it prompted for me for my password. After that, all subsequent runs, it did not prompt for my password.

On Debian derivatives such as Ubuntu, use apt. Check the apt repository for the versions of Python available to you. Then, run a command similar to the following, substituting the correct package name:

sudo apt-get install python3

On Red Hat and derivatives, use yum. Check the yum repository for the versions of Python available to you. Then, run a command similar to the following, substituting the correct package name:

sudo yum install python36

On SUSE and derivatives, use zypper. Check the repository for the versions of Python available to you. Then. run a command similar to the following, substituting the correct package name:

sudo zypper install python3

<div id="sample"></div>   
 <form>
        <fieldset>
            <legend>Add New Contact</legend>
            <input type="text" name="fullname" placeholder="First name and last name" required /> <br />
            <input type="email" name="email" placeholder="[email protected]" required /> <br />
            <input type="text" name="phone" placeholder="Personal phone number: mobile, home phone etc." required /> <br />
            <input type="submit" name="submit" id= "submitButton" class="button" value="Add Contact" onClick="" />
            <input type="button" name="cancel" class="button" value="Reset" />
        </fieldset>
    </form>

<script>

    $(document).ready(function(){
         $("#submitButton").click(function(){
            $("#sample").load(filenameofyourfunction?the the variable you need);
         });
    });

</script>

Also, if all you are trying to do is break up the main.go file into multiple files, then just name the other files "package main" as long as you only define the main function in one of those files, you are good to go.

Try this:

cp Folder1/* Folder2/

You have to ask if the current text is already shown with dots, the function PasswordTransformationMethod.getInstance() allow you to do that.

This is my funtion in kotlin:

        fun hideAndShowPassword(editText: EditText, indicator: ImageView) {

        if (editText.transformationMethod == PasswordTransformationMethod.getInstance()) {
            editText.transformationMethod = HideReturnsTransformationMethod.getInstance()
            indicator.setImageDrawable(
                ContextCompat.getDrawable(
                    editText.context,
                    R.drawable.eye
                )
            )
            indicator.imageTintList =
                ContextCompat.getColorStateList(editText.context, R.color.colorTintIcons)
        } else {
            editText.transformationMethod = PasswordTransformationMethod.getInstance()
            indicator.setImageDrawable(
                ContextCompat.getDrawable(
                    editText.context,
                    R.drawable.eye_off
                )
            )
            indicator.imageTintList =
                ContextCompat.getColorStateList(editText.context, R.color.colorTintIcons)
        }

        editText.setSelection(editText.text.length)
    }

Suggest you not to use Count because count always makes extra loads for db use SELECT 1 and it returns 1 if your record right there otherwise it returns null and you can handle it.

Do you have to use Bootstrap for this? Here's a basic HTML/CSS example for obtaining this look that doesn't use any Bootstrap:

HTML:

<div class="bottom">
    <div class="box-content right">Rich Media Ad Production</div>
    <div class="box-content right">Web Design & Development</div>
    <div class="box-content right">Mobile Apps Development</div>
    <div class="box-content">Creative Design</div>
</div>
<div>
    <div class="box-content right">Web Analytics</div>
    <div class="box-content right">Search Engine Marketing</div>
    <div class="box-content right">Social Media</div>
    <div class="box-content">Quality Assurance</div>
</div>

CSS:

.box-content {
    display: inline-block;
    width: 200px;
    padding: 10px;
}

.bottom {
    border-bottom: 1px solid #ccc;
}

.right {
    border-right: 1px solid #ccc;
}

Here is the working Fiddle.

UPDATE

If you must use Bootstrap, here is a semi-responsive example that achieves the same effect, although you may need to write a few additional media queries.

HTML:

<div class="row">
    <div class="col-xs-3">Rich Media Ad Production</div>
    <div class="col-xs-3">Web Design & Development</div>
    <div class="col-xs-3">Mobile Apps Development</div>
    <div class="col-xs-3">Creative Design</div>
</div>
<div class="row">
    <div class="col-xs-3">Web Analytics</div>
    <div class="col-xs-3">Search Engine Marketing</div>
    <div class="col-xs-3">Social Media</div>
    <div class="col-xs-3">Quality Assurance</div>
</div>

CSS:

.row:not(:last-child) {
    border-bottom: 1px solid #ccc;
}

.col-xs-3:not(:last-child) {
    border-right: 1px solid #ccc;
}

Here is another working Fiddle.

Note:

Note that you may also use the <hr> element to insert a horizontal divider in Bootstrap as well if you'd like.

I know this question has been answered to the death, but it doesn't solve the problem where you want to use your browser router with proxy pass, where you can't use root.

For me the solution is pretty simple.

say you have a url that's pointing to some port.

location / {
  proxy_pass http://127.0.0.1:30002/;
  proxy_set_header    Host            $host;
  port_in_redirect    off;
}

and now because of the browser router sub paths are broken. However you know what the sub paths are.

The solution to this? For sub path /contact

# just copy paste.
location /contact/ {
  proxy_pass http://127.0.0.1:30002/;
  proxy_set_header    Host            $host;
}

Nothing else I've tried works, but this simple fix works like a damn charm.

Cloning a specific tag, might return 'detached HEAD' state.

As a workaround, try to clone the repo first, and then checkout a specific tag. For example:

repo_url=https://github.com/owner/project.git
repo_dir=$(basename $repo_url .git)
repo_tag=0.5

git clone --single-branch $repo_url # using --depth 1 can show no tags
git --work-tree=$repo_dir --git-dir=$repo_dir/.git checkout tags/$repo_tag

Note: Since Git 1.8.5, you can use -C <path>, instead of --work-tree and --git-dir.

Selenium WebDriver

1. WebDriver.Close() This method is used to close the current open window. It closes the current open window on which driver has focus on.

2. WebDriver.Quit() This method is used to destroy the instance of WebDriver. It closes all Browser Windows associated with that driver and safely ends the session. WebDriver.Quit() calls Dispose.

3. WebDriver.Dispose() This method closes all Browser windows and safely ends the session

You can also use the following alternative realpath.

Create a file called path.php

Put the following code inside by specifying the name of the created file.

<?php 
    echo realpath('path.php'); 
?>

A php file that you can move to all your folders to always have the absolute path from where the executed file is located.

IE 8 will support the window.navigator.onLine property.

But of course that doesn't help with other browsers or operating systems. I predict other browser vendors will decide to provide that property as well given the importance of knowing online/offline status in Ajax applications.

Until that happens, either XHR or an Image() or <img> request can provide something close to the functionality you want.

Update (2014/11/16)

Major browsers now support this property, but your results will vary.

Quote from Mozilla Documentation:

In Chrome and Safari, if the browser is not able to connect to a local area network (LAN) or a router, it is offline; all other conditions return true. So while you can assume that the browser is offline when it returns a false value, you cannot assume that a true value necessarily means that the browser can access the internet. You could be getting false positives, such as in cases where the computer is running a virtualization software that has virtual ethernet adapters that are always "connected." Therefore, if you really want to determine the online status of the browser, you should develop additional means for checking.

In Firefox and Internet Explorer, switching the browser to offline mode sends a false value. All other conditions return a true value.

You need to add the package containing the executable pg_config.

A prior answer should have details you need: pg_config executable not found

I experienced an issue where background images with spaces in the filename where causing the style to not be applied. To correct this I had to ensure the string path was encapsulated in single quotes.

Note the escaped \' in my example below.

<div :style="{
    height: '100px',
    backgroundColor: '#323232',
    backgroundImage: 'url(\'' + event.image + '\')',
    backgroundPosition: 'center center',
    backgroundSize: 'cover'
    }">
</div>

--force-reinstall

doesn't appear to force reinstall using python2.7 with pip-1.5

I've had to use

This happens to me, since I am designing my database, I notice that I change my seed on my main table, now the relational table has no foreign key on the main table.

So I need to truncate both tables, and it now works!

Richard Schneider is right. use code below to fetch data from site which is not utf8 charset will get wrong string.

using (Stream stream = response.GetResponseStream())
{
   StreamReader reader = new StreamReader(stream, Encoding.UTF8);
   String responseString = reader.ReadToEnd();
}

You can't implicitly return with an if, you would need the braces:

let adults = family.filter(person => { if (person.age > 18) return person} );

It can be simplified though:

let adults = family.filter(person => person.age > 18);

Let's take look at what breakpoint() can do for you in 3.7+.

I have installed ipdb and pdbpp, which are both enhanced debuggers, via

pip install pdbpp
pip install ipdb

My test script, really doesn't do much, just calls breakpoint().

#test_188_breakpoint.py
myvars=dict(foo="bar")
print("before breakpoint()")
breakpoint()   # 
print(f"after breakpoint myvars={myvars}")

breakpoint() is linked to the PYTHONBREAKPOINT environment variable.

CASE 1: disabling breakpoint()

You can set the variable via bash as usual

export PYTHONBREAKPOINT=0

This turns off breakpoint() where it does nothing (as long as you haven't modified sys.breakpointhook() which is outside of the scope of this answer).

This is what a run of the program looks like:

(venv38) myuser@explore$ export PYTHONBREAKPOINT=0
(venv38) myuser@explore$ python test_188_breakpoint.py
before breakpoint()
after breakpoint myvars={'foo': 'bar'}
(venv38) myuser@explore$

Didn't stop, because I disabled breakpoint. Something that pdb.set_trace() can't do !

CASE 2: using the default pdb behavior:

Now, let's unset PYTHONBREAKPOINT which puts us back to normal, enabled-breakpoint behavior (it's only disabled when 0 not when empty).

(venv38) myuser@explore$ unset PYTHONBREAKPOINT
(venv38) myuser@explore$ python test_188_breakpoint.py
before breakpoint()
[0] > /Users/myuser/kds2/wk/explore/test_188_breakpoint.py(6)<module>()
-> print(f"after breakpoint myvars={myvars}")
(Pdb++) print("pdbpp replaces pdb because it was installed")
pdbpp replaces pdb because it was installed
(Pdb++) c
after breakpoint myvars={'foo': 'bar'}

It stopped, but I actually got pdbpp because it replaces pdb entirely while installed. If I unistalled pdbpp, I'd be back to normal pdb.

Note: a standard pdb.set_trace() would still get me pdbpp

CASE 3: calling a custom debugger

But let's call ipdb instead. This time, instead of setting the environment variable, we can use bash to set it only for this one command.

(venv38) myuser@explore$ PYTHONBREAKPOINT=ipdb.set_trace py test_188_breakpoint.py
before breakpoint()
> /Users/myuser/kds2/wk/explore/test_188_breakpoint.py(6)<module>()
      5 breakpoint()
----> 6 print(f"after breakpoint myvars={myvars}")
      7

ipdb> print("and now I invoked ipdb instead")
and now I invoked ipdb instead
ipdb> c
after breakpoint myvars={'foo': 'bar'}

Essentially, what it does, when looking at $PYTHONBREAKPOINT:

from ipdb import set_trace  # function imported on the right-most `.`
set_trace()

Again, much cleverer than a plain old pdb.set_trace()

in practice? I'd probably settle on a debugger.

Say I want ipdb always, I would:

• export it via .profile or similar.
• disable on a command by command basis, without modifying the normal value

Example (pytest and debuggers often make for unhappy couples):

(venv38) myuser@explore$ export PYTHONBREAKPOINT=ipdb.set_trace
(venv38) myuser@explore$ echo $PYTHONBREAKPOINT
ipdb.set_trace
(venv38) myuser@explore$ PYTHONBREAKPOINT=0 pytest test_188_breakpoint.py

p.s.

I'm using bash under macos, any posix shell will behave substantially the same. Windows, either powershell or DOS, may have different capabilities, especially around PYTHONBREAKPOINT=<some value> <some command> to set a environment variable only for one command.

This answer predates version 1.1.5 where a proper ternary in the $parse function wasn't available. Use this answer if you're on a lower version, or as an example of filters:

angular.module('myApp.filters', [])
  
  .filter('conditional', function() {
    return function(condition, ifTrue, ifFalse) {
      return condition ? ifTrue : ifFalse;
    };
  });

And then use it as

<i ng-class="checked | conditional:'icon-check':'icon-check-empty'"></i>

I think the problem is here:

[contains(text()='Some text')]

To break this down,

1. The [] are a conditional that operates on each individual node in that node set -- each span node in your case. It matches if any of the individual nodes it operates on match the conditions inside the brackets.
2. text() is a selector that matches all of the text nodes that are children of the context node -- it returns a node set.
3. contains is a function that operates on a string. If it is passed a node set, the node set is converted into a string by returning the string-value of the node in the node-set that is first in document order.

You should try to change this to

[text()[contains(.,'Some text')]]

1. The outer [] are a conditional that operates on each individual node in that node set text() is a selector that matches all of the text nodes that are children of the context node -- it returns a node set.

2. The inner [] are a conditional that operates on each node in that node set.

3. contains is a function that operates on a string. Here it is passed an individual text node (.).

This is how I used this is as an example:

CAST(vAvgMaterialUnitCost.`avgUnitCost` AS DECIMAL(11,2)) * woMaterials.`qtyUsed` AS materialCost

If you are looking for features that notebooks in JupyterLab have that traditional Jupyter Notebooks do not, check out the JupyterLab notebooks documentation. There is a simple video showing how to use each of the features in the documentation link.

JupyterLab notebooks have the following features and more:

• Drag and drop cells to rearrange your notebook
• Drag cells between notebooks to quickly copy content (since you can
  have more than one open at a time)
• Create multiple synchronized views of a single notebook
• Themes and customizations: Dark theme and increase code font size

Add CDATA to your string resource

A portion of code originally from Example Depot for listing all of the aliases in a key store:

    // Load input stream into keystore
    keystore.load(is, password.toCharArray());

    // List the aliases
    Enumeration aliases = keystore.aliases();
    for (; aliases.hasMoreElements(); ) {
        String alias = (String)aliases.nextElement();

        // Does alias refer to a private key?
        boolean b = keystore.isKeyEntry(alias);

        // Does alias refer to a trusted certificate?
        b = keystore.isCertificateEntry(alias);
    }

The exporting of private keys came up on the Sun forums a couple of months ago, and u:turingcompleter came up with a DumpPrivateKey class to stitch into your app.

import java.io.FileInputStream;
import java.security.Key;
import java.security.KeyStore;

    static public void main(String[] args)
    throws Exception {
        if(args.length < 3) {
          throw new IllegalArgumentException("expected args: Keystore filename, Keystore password, alias, <key password: default same tha

        }
        final String keystoreName = args[0];
        final String keystorePassword = args[1];
        final String alias = args[2];
        final String keyPassword = getKeyPassword(args,keystorePassword);
        KeyStore ks = KeyStore.getInstance("jks");
        ks.load(new FileInputStream(keystoreName), keystorePassword.toCharArray());
        Key key = ks.getKey(alias, keyPassword.toCharArray());
        String b64 = new BASE64Encoder().encode(key.getEncoded());
        System.out.println("-----BEGIN PRIVATE KEY-----");
        System.out.println(b64);
        System.out.println("-----END PRIVATE KEY-----");
    }
    private static String getKeyPassword(final String[] args, final String keystorePassword)
    {
       String keyPassword = keystorePassword; // default case
       if(args.length == 4) {
         keyPassword = args[3];
       }
       return keyPassword;
    }
}

Note: this use Sun package, which is a "bad thing".

You have "runs on actual browser" as a pro, but in my experience that is a con because it is slow. But what makes it valuable is the lack of sufficient JS emulation from the non-browser alternatives. It could be that if your JS is complex enough that only an in browser test will suffice, but there are a couple more options to consider:

HtmlUnit: "It has fairly good JavaScript support (which is constantly improving) and is able to work even with quite complex AJAX libraries, simulating either Firefox or Internet Explorer depending on the configuration you want to use." If its emulation is good enough for your use then it will be much faster than driving a browser.

But maybe HtmlUnit has good enough JS support but you don't like Java? Then maybe:

Celerity: Watir API running on JRuby backed by HtmlUnit.

or similarly

Schnell: another JRuby wrapper of HtmlUnit.

Of course if HtmlUnit isn't good enough and you have to drive a browser then you might consider Watir to drive your JS.

Yes - document.location = "http://my.new.url.com"

You can also retrieve it the same way eg.

var myURL = document.location;
document.location = myURL + "?a=parameter";

The location object has a number of useful properties too:

hash            Returns the anchor portion of a URL
host            Returns the hostname and port of a URL
hostname        Returns the hostname of a URL
href            Returns the entire URL
pathname        Returns the path name of a URL
port            Returns the port number the server uses for a URL
protocol        Returns the protocol of a URL
search          Returns the query portion of a URL

EDIT: Setting the hash of the document.location shouldn't reload the page, just alter where on the page the focus is. So updating to #myId will scroll to the element with id="myId". If the id doesn't exist I believe nothing will happen? (Need to confirm on various browsers though)

EDIT2: To make it clear, not just in a comment: You can't update the whole URL with javascript without changing the page, this is a security restriction. Otherwise you could click on a link to a random page, crafted to look like gmail, and instantly change the URL to www.gmail.com and steal people's login details.
You can change the part after the domain on some browsers to cope with AJAX style things, but that's already been linked to by Osiris. What's more, you probably shouldn't do this, even if you could. The URL tells the user where he/she is on your site. If you change it without changing the page contents, it's becomes a little confusing.

Thanks to all for your help - I was off this issue for a couple of days and just came back to it - was able to cobble this together - not the most elegant code, but it works for my purposes - thought I'd share if anyone else encounters this issue:

public class Statistics
{
    public Trendline CalculateLinearRegression(int[] values)
    {
        var yAxisValues = new List<int>();
        var xAxisValues = new List<int>();

        for (int i = 0; i < values.Length; i++)
        {
            yAxisValues.Add(values[i]);
            xAxisValues.Add(i + 1);
        }

        return new Trendline(yAxisValues, xAxisValues);
    }
}

public class Trendline
{
    private readonly IList<int> xAxisValues;
    private readonly IList<int> yAxisValues;
    private int count;

        this.yAxisValues = yAxisValues;
        this.xAxisValues = xAxisValues;

        this.xAxisValuesSum = this.xAxisValues.Sum();
        this.xxSum = 0;
        this.xySum = 0;

        for (int i = 0; i < this.count; i++)
        {

        }

        this.Slope = this.CalculateSlope();
        this.Intercept = this.CalculateIntercept();
        this.Start = this.CalculateStart();

    }

    private int CalculateSlope()
    {
        try
        {
            return ((this.count*this.xySum) - (this.xAxisValuesSum*this.yAxisValuesSum))/((this.count*this.xxSum) - (this.xAxisValuesSum*this.xAxisValuesSum));
        }
        catch (DivideByZeroException)
        {
            return 0;
        }
    }

    private int CalculateIntercept()
    {
        return (this.yAxisValuesSum - (this.Slope*this.xAxisValuesSum))/this.count;
    }

    private int CalculateStart()
    {
        return (this.Slope*this.xAxisValues.First()) + this.Intercept;
    }

    private int CalculateEnd()
    {
        return (this.Slope*this.xAxisValues.Last()) + this.Intercept;
    }
}

The cleanest way, as far as I know:

1. add your JSP variable to an HTML element's data-* attribute
2. then read this value via Javascript when required

My opinion regarding the current solutions on this SO page: reading "directly" JSP values using java scriplet inside actual javascript code is probably the most disgusting thing you could do. Makes me wanna puke. haha. Seriously, try to not do it.

The HTML part without JSP:

<body data-customvalueone="1st Interpreted Jsp Value" data-customvaluetwo="another Interpreted Jsp Value">
    Here is your regular page main content
</body>

The HTML part when using JSP:

<body data-customvalueone="${beanName.attrName}" data-customvaluetwo="${beanName.scndAttrName}">
    Here is your regular page main content
</body>

The javascript part (using jQuery for simplicity):

<script type="text/JavaScript" src="//cdnjs.cloudflare.com/ajax/libs/jquery/2.1.1/jquery.js"></script>
<script type="text/javascript">
    jQuery(function(){
        var valuePassedFromJSP = $("body").attr("data-customvalueone");
        var anotherValuePassedFromJSP = $("body").attr("data-customvaluetwo");

        alert(valuePassedFromJSP + " and " + anotherValuePassedFromJSP + " are the values passed from your JSP page");
});
</script>

And here is the jsFiddle to see this in action http://jsfiddle.net/6wEYw/2/

Resources:

• HTML 5 data-* attribute: https://developer.mozilla.org/en-US/docs/Web/Guide/HTML/Using_data_attributes
• Include javascript into html file Include JavaScript file in HTML won't work as <script .... />
• CSS selectors (also usable when selecting via jQuery) https://developer.mozilla.org/en-US/docs/Web/Guide/CSS/Getting_started/Selectors
• Get an HTML element attribute via jQuery http://api.jquery.com/attr/

$(document).ready(function() {
       scope.$apply(function() {
                applyHeight();
            });
});

This also ensures that all the scripts have been loaded before the execution of the statements. If you dont need that you can use

$(window).load(function() {
       scope.$apply(function() {
                applyHeight();
            });
});

From ?read.table: The number of data columns is determined by looking at the first five lines of input (or the whole file if it has less than five lines), or from the length of col.names if it is specified and is longer. This could conceivably be wrong if fill or blank.lines.skip are true, so specify col.names if necessary.

So, perhaps your data file isn't clean. Being more specific will help the data import:

d = read.table("foobar.txt", 
               sep="\t", 
               col.names=c("id", "name"), 
               fill=FALSE, 
               strip.white=TRUE)

will specify exact columns and fill=FALSE will force a two column data frame.

Maybe you want unpack elements of array, I don't know if I got it, but below a example:

def my_func(*args):
    for a in args:
        print a

my_func(*[1,2,3,4])
my_list = ['a','b','c']
my_func(*my_list)

I was looking around for a different issue but same cause. The issue is that the dialog set focus to the first <a href="">.</a> it finds. So if you have a lot of text in your dialog and scroll bars appear you could have the situation where the scroll bar will be scrolled to the bottom. I believe this also fixes the first persons question. Although the others do as well.

The simple easy to understand fix. <a id="someid" href="#">.</a> as the first line in your dialog div.

EXAMPLE:

 <div id="dialogdiv" title="some title">
    <a id="someid" href="#">.</a>
    <p>
        //the rest of your stuff
    </p>
</div>

Where your dialog is initiated

$(somediv).dialog({
        modal: true,
        open: function () { $("#someid").hide(); otherstuff or function },
        close: function () { $("#someid").show(); otherstuff or function }
    });

The above will have nothing focused and the scroll bars will remain at the top where it belongs. The <a> gets focus but is then hidden. So the overall effect is the desired effect.

I know this is an old thread but as for as the UI docs there is no fix to this. This does not require blur or focus to work. Not sure if it is the most elegant. But it just makes sense and easy to explain to anyone.

want to convert the column name Amount as float number with 2 decimals

CASE WHEN EXISTS (SELECT Amount From InvoiceFee Ifee WHERE IFEE.InvoiceId = 
DIR.InvoiceId AND FeeId = 'Freight Cost')
     THEN  CAST ((SELECT Amount From InvoiceFee Ifee WHERE IFEE.InvoiceId = 
DIR.InvoiceId AND FeeId = 'Freight Cost') AS VARCHAR)
            ELSE '' END AS FCost,

Programmatically, you can try:

editText.getBackground().mutate().setColorFilter(getResources().getColor(android.R.color.holo_red_light), PorterDuff.Mode.SRC_ATOP);

Did you 'export' in your .bashrc?

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:"/path/to/library"

read with IFS are perfect for this:

$ IFS=- read var1 var2 <<< ABCDE-123456
$ echo "$var1"
ABCDE
$ echo "$var2"
123456

Edit:

Here is how you can read each individual character into array elements:

$ read -a foo <<<"$(echo "ABCDE-123456" | sed 's/./& /g')"

Dump the array:

$ declare -p foo
declare -a foo='([0]="A" [1]="B" [2]="C" [3]="D" [4]="E" [5]="-" [6]="1" [7]="2" [8]="3" [9]="4" [10]="5" [11]="6")'

If there are spaces in the string:

$ IFS=$'\v' read -a foo <<<"$(echo "ABCDE 123456" | sed 's/./&\v/g')"
$ declare -p foo
declare -a foo='([0]="A" [1]="B" [2]="C" [3]="D" [4]="E" [5]=" " [6]="1" [7]="2" [8]="3" [9]="4" [10]="5" [11]="6")'

In Java its Webelement.getText() . Not sure about python.

If you are facing problem after implementing all below mentioned new libraries. I was facing the above mentioned same problem on this 'com.android.support:appcompat-v7:27.1.0' compatible verions.

implementation 'com.android.support:appcompat-v7:27.1.0'
implementation 'com.android.support:design:27.1.0'
implementation 'com.android.support:appcompat-v7:27.1.0'
implementation 'com.android.support:mediarouter-v7:27.1.0'
implementation 'com.android.support:recyclerview-v7:27.1.0'
implementation 'com.android.support:cardview-v7:27.1.0'
implementation 'com.android.support:support-v13:27.1.0'
implementation 'com.android.support:support-v4:27.1.0'

I just replace this

'com.android.support:appcompat-v7:27.1.0'

to this

'com.android.support:appcompat-v7:27.0.1'

df[df.columns[i]]

where i is the position/number of the column(starting from 0).

So, i = 0 is for the first column.

You can also get the last column using i = -1

There are plenty of templating systems that offer more compact syntax for your views. Smarty is venerable and popular. This article lists 10 others.

For that single rule you have, there isn't any shorter way to do it. The child combinator is the same in CSS and in Sass/SCSS and there's no alternative to it.

However, if you had multiple rules like this:

#foo > ul > li > ul > li > a:nth-child(3n+1) {
    color: red;
}

#foo > ul > li > ul > li > a:nth-child(3n+2) {
    color: green;
}

#foo > ul > li > ul > li > a:nth-child(3n+3) {
    color: blue;
}

You could condense them to one of the following:

/* Sass */
#foo > ul > li > ul > li
    > a:nth-child(3n+1)
        color: red
    > a:nth-child(3n+2)
        color: green
    > a:nth-child(3n+3)
        color: blue

/* SCSS */
#foo > ul > li > ul > li {
    > a:nth-child(3n+1) { color: red; }
    > a:nth-child(3n+2) { color: green; }
    > a:nth-child(3n+3) { color: blue; }
}

Here's a JavaScript function which validates a ZIP/postal code based on a country code. It allows somewhat liberal formatting. You could add cases for other countries as well. Note that the default case allows empty postal codes since not all countries use them.

function isValidPostalCode(postalCode, countryCode) {
    switch (countryCode) {
        case "US":
            postalCodeRegex = /^([0-9]{5})(?:[-\s]*([0-9]{4}))?$/;
            break;
        case "CA":
            postalCodeRegex = /^([A-Z][0-9][A-Z])\s*([0-9][A-Z][0-9])$/;
            break;
        default:
            postalCodeRegex = /^(?:[A-Z0-9]+([- ]?[A-Z0-9]+)*)?$/;
    }
    return postalCodeRegex.test(postalCode);
}

FYI The second link referring to vanity ZIP codes appears to have been an April Fool's joke.

You can set the border properties on the CALayer by accessing the layer property of the button.

First, add Quartz

#import <QuartzCore/QuartzCore.h>

Set properties:

myButton.layer.borderWidth = 2.0f;
myButton.layer.borderColor = [UIColor greenColor].CGColor;

See:

https://developer.apple.com/documentation/quartzcore/calayer#//apple_ref/occ/cl/CALayer

The CALayer in the link above allows you to set other properties like corner radius, maskToBounds etc...

Also, a good article on button fun:

1. An independent parent is the best practice for sharing configuration and options across otherwise uncoupled components. Apache has a parent pom project to share legal notices and some common packaging options.

2. If your top-level project has real work in it, such as aggregating javadoc or packaging a release, then you will have conflicts between the settings needed to do that work and the settings you want to share out via parent. A parent-only project avoids that.

3. A common pattern (ignoring #1 for the moment) is have the projects-with-code use a parent project as their parent, and have it use the top-level as a parent. This allows core things to be shared by all, but avoids the problem described in #2.

4. The site plugin will get very confused if the parent structure is not the same as the directory structure. If you want to build an aggregate site, you'll need to do some fiddling to get around this.

5. Apache CXF is an example the pattern in #2.

Although optimally it would be nice if your code can run parallel, it can be the case you're simply using a thread so you do not block the UI thread, even if your app's usage flow will have to wait for it.

You've got pretty much 2 options here;

1. You can execute the code you want waiting, in the AsyncTask itself. If it has to do with updating the UI(thread), you can use the onPostExecute method. This gets called automatically when your background work is done.

2. If you for some reason are forced to do it in the Activity/Fragment/Whatever, you can also just make yourself a custom listener, which you broadcast from your AsyncTask. By using this, you can have a callback method in your Activity/Fragment/Whatever which only gets called when you want it: aka when your AsyncTask is done with whatever you had to wait for.

Trick to update props if they are array :

import React, { Component } from 'react';
import {
  AppRegistry,
  StyleSheet,
  Text,
  View,
  Button
} from 'react-native';

class Counter extends Component {
  constructor(props) {
    super(props);
      this.state = {
        count: this.props.count
      }
    }
  increment(){
    console.log("this.props.count");
    console.log(this.props.count);
    let count = this.state.count
    count.push("new element");
    this.setState({ count: count})
  }
  render() {

    return (
      <View style={styles.container}>
        <Text>{ this.state.count.length }</Text>
        <Button
          onPress={this.increment.bind(this)}
          title={ "Increase" }
        />
      </View>
    );
  }
}

Counter.defaultProps = {
 count: []
}

export default Counter
const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
    backgroundColor: '#F5FCFF',
  },
  welcome: {
    fontSize: 20,
    textAlign: 'center',
    margin: 10,
  },
  instructions: {
    textAlign: 'center',
    color: '#333333',
    marginBottom: 5,
  },
});

Error : An error occurred (AccessDenied) when calling the PutObject operation: Access Denied

I solved the issue by passing Extra Args parameter as PutObjectAcl is disabled by company policy.

s3_client.upload_file('./local_file.csv', 'bucket-name', 'path', ExtraArgs={'ServerSideEncryption': 'AES256'})

@mysql_result(mysql_query("SELECT DATABASE();"),0)

If no database selected, or there is no connection it returns NULL otherwise the name of the selected database.

Your error is in UpdaterServiceManager in onCreate and showNotification method.

You are trying to show notification from Service using Activity Context. Whereas Every Service has its own Context, just use the that. You don't need to pass a Service an Activity's Context.I don't see why you need a specific Activity's Context to show Notification.

Put your createNotification method in UpdateServiceManager.class. And remove CreateNotificationActivity not from Service.

You cannot display an application window/dialog through a Context that is not an Activity. Try passing a valid activity reference

You can also make it this way :

<SeekBar
    android:id="@+id/redSeekBar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:progressDrawable="@color/red"
    android:maxHeight="3dip"/>

Hope it will help!

You may perform soap call as post over http with certain headers. I solved this question without additional libraries like ksoap2 Here is live code getting orders from soap service

You can get an objective c compiler that will work with Windows and play nice with Visual Studio 2008\2010 here.

open-c flite

Just download the latest source. You don't need to build all of CF-Lite there is a solution called objc.sln. You will need to fix a few of the include paths but then it will build just fine. There is even a test project included so you can see some objective-c .m files being compiled and working in visual studio. One sad thing is it only works with Win32 not x64. There is some assembly code that would need to be written for x64 for it to support that.

1. Create Black Color: <color name="blackColorPrimary">#000001</color> (not #000000)
2. Write in Style: <item name="android:navigationBarColor" tools:targetApi="lollipop">@color/blackColorPrimary</item>

Problem is that android higher version make trasparent for #000000

Give this a try :P

s = '#'.repeat(10)_x000D_
_x000D_
document.body.innerHTML = s

Using @Autowired or ApplicationContext.getBean() is really the same thing. In both ways you get the bean that is configured in your context and in both ways your code depends on spring. The only thing you should avoid is instantiating your ApplicationContext. Do this only once! In other words, a line like

ApplicationContext context = new ClassPathXmlApplicationContext("AppContext.xml");

should only be used once in your application.

use this.animationStop, not use this.animationStop ( )

animationRun(){
    this.sliderClass.anim = true;
    setTimeout(this.animationStop, 500);
},

I was able to solve my particular version of this problem (had to make /customer.html route to /customer, trailing slashes not allowed) using the solution at https://stackoverflow.com/a/13082446/1454265, and substituting path="*.html".

You'll have to jailbreak your device.

This worked for me:

=(col_name]/60/60/24)+(col_name-1)

Another thing that can cause this error is creating a model with the centering/scaling standardize function from the arm package -- m <- standardize(lm(y ~ x, data = train))

If you then try predict(m), you get the same error as in this question.

Slightly different: Using Python 3 and print several variables in the same line:

print("~~Create new DB:",argv[5],"; with user:",argv[3],"; and Password:",argv[4]," ~~")

Just write

System.Diagnostics.Process.Start(@"file path");

example

System.Diagnostics.Process.Start(@"C:\foo.jpg");
System.Diagnostics.Process.Start(@"C:\foo.doc");
System.Diagnostics.Process.Start(@"C:\foo.dxf");
...

And shell will run associated program reading it from the registry, like usual double click does.

You are getting confused with transclude: true, which would append the inner content.

replace: true means that the content of the directive template will replace the element that the directive is declared on, in this case the <div myd1> tag.

For example without replace:true

<div myd1><span class="replaced" myd1="">directive template1</span></div>

and with replace:true

<span class="replaced" myd1="">directive template1</span>

As you can see in the latter example, the div tag is indeed replaced.

I'm a little surprised nobody has suggested the most obvious solution:

grep -v '^#' filename

This solves the problem as stated.

But note that a common convention is for everything from a # to the end of a line to be treated as a comment:

sed 's/#.*$//' filename

though that treats, for example, a # character within a string literal as the beginning of a comment (which may or may not be relevant for your case) (and it leaves empty lines).

A line starting with arbitrary whitespace followed by # might also be treated as a comment:

grep -v '^ *#' filename

if whitespace is only spaces, or

grep -v '^[  ]#' filename

where the two spaces are actually a space followed by a literal tab character (type "control-v tab").

For all these commands, omit the filename argument to read from standard input (e.g., as part of a pipe).

You don't have to define a separate variable in the widget scope, just do it inline:

TextField(
  controller: TextEditingController()..text = 'Your initial value',
  onChanged: (text) => {},
)

limit = 75
info = data[:limit] + '..' * (len(data) > limit)

1) Update Devise so that it can handle Rails 4.0 by adding this line to your application's Gemfile:

gem 'devise', '3.0.0.rc' 

Then execute:

$ bundle

2) Add the old functionality of attr_accessible again to rails 4.0

Try to use attr_accessible and don't comment this out.

Add this line to your application's Gemfile:

gem 'protected_attributes'

Then execute:

$ bundle

If you use any(lst) you see that lst is the iterable, which is a list of some items. If it contained [0, False, '', 0.0, [], {}, None] (which all have boolean values of False) then any(lst) would be False. If lst also contained any of the following [-1, True, "X", 0.00001] (all of which evaluate to True) then any(lst) would be True.

In the code you posted, x > 0 for x in lst, this is a different kind of iterable, called a generator expression. Before generator expressions were added to Python, you would have created a list comprehension, which looks very similar, but with surrounding []'s: [x > 0 for x in lst]. From the lst containing [-1, -2, 10, -4, 20], you would get this comprehended list: [False, False, True, False, True]. This internal value would then get passed to the any function, which would return True, since there is at least one True value.

But with generator expressions, Python no longer has to create that internal list of True(s) and False(s), the values will be generated as the any function iterates through the values generated one at a time by the generator expression. And, since any short-circuits, it will stop iterating as soon as it sees the first True value. This would be especially handy if you created lst using something like lst = range(-1,int(1e9)) (or xrange if you are using Python2.x). Even though this expression will generate over a billion entries, any only has to go as far as the third entry when it gets to 1, which evaluates True for x>0, and so any can return True.

If you had created a list comprehension, Python would first have had to create the billion-element list in memory, and then pass that to any. But by using a generator expression, you can have Python's builtin functions like any and all break out early, as soon as a True or False value is seen.

I think list comprehension is one of the cleanest ways that doesn't need any additional imports:

>>> d={"foo": 1, "bar": 2, "baz": 3}
>>> a = [d.get(k) for k in ["foo", "bar", "baz"]]
>>> a
[1, 2, 3]

Of if you want the values as individual variables then use multiple-assignment:

>>> a,b,c = [d.get(k) for k in ["foo", "bar", "baz"]]
>>> a,b,c
(1, 2, 3)

i prefer to create folder his name is Utils and inside create page index that contain what that think you helper by

const findByAttr = (component,attr) => {
    const wrapper=component.find(`[data-test='${attr}']`);
    return wrapper;
}

const FUNCTION_NAME = (component,attr) => {
    const wrapper=component.find(`[data-test='${attr}']`);
    return wrapper;
}

export {findByAttr, FUNCTION_NAME}

When you need to use this it should be imported as use "{}" because you did not use the default keyword look

 import {FUNCTION_NAME,findByAttr} from'.whare file is store/utils/index'

I think this will happen if you'll use 'async defer' for (the file that contains the filter) while working with angularjs:

<script src="js/filter.js" type="text/javascript" async defer></script>

if you do, just remove 'async defer'.

Use the values attribute to return the values as a np array and then use [0] to get the first value:

In [4]:
df.loc[df.Letters=='C','Letters'].values[0]

Out[4]:
'C'

EDIT

I personally prefer to access the columns using subscript operators:

df.loc[df['Letters'] == 'C', 'Letters'].values[0]

This avoids issues where the column names can have spaces or dashes - which mean that accessing using ..

If you do not care about repetitive form elements with the same name, then you can do:

var data = $("form.login").serializeArray();
var formData = _.object(_.pluck(data, 'name'), _.pluck(data, 'value'));

I am just beginning to dig deeper into git, so not sure if I understand correctly, but I think the correct answer to the OP's question is that you can run git log --all with a format specification like this: git log --all --pretty=format:'%h: %s %d'. This marks the current checked out version as (HEAD) and you can just grab the next one from the list.

BTW, add an alias like this to your .gitconfig with a slightly better format and you can run git hist --all:

  hist = log --pretty=format:\"%h %ai | %s%d [%an]\" --graph

Regarding the relative versions, I found this post, but it only talks about older versions, there is probably nothing to refer to the newer versions.

For the UPDATE

Use:

UPDATE table1 
   SET col1 = othertable.col2,
       col2 = othertable.col3 
  FROM othertable 
 WHERE othertable.col1 = 123;

For the INSERT

Use:

INSERT INTO table1 (col1, col2) 
SELECT col1, col2 
  FROM othertable

You don't need the VALUES syntax if you are using a SELECT to populate the INSERT values.

For anyone encountering a similar situation I was able to solve the issue above as follows:

1. Regenerate your pkcs12 file as follows:

   openssl pkcs12 -in oldpkcs.p12 -out keys -passout pass:tmp
   openssl pkcs12 -in keys -export -out new.p12 -passin pass:tmp -passout pass:newpasswd
   

2. Import the CA certificate from server into a TrustStore ( either your own, or the java keystore in $JAVA_HOME/jre/lib/security/cacerts, password: changeit).

3. Set the following system properties:

   System.setProperty("javax.net.ssl.trustStore", "myTrustStore");
   System.setProperty("javax.net.ssl.trustStorePassword", "changeit");
   System.setProperty("javax.net.ssl.keyStoreType", "pkcs12");
   System.setProperty("javax.net.ssl.keyStore", "new.p12");
   System.setProperty("javax.net.ssl.keyStorePassword", "newpasswd");
   

4. Test ur url.

I searched now over 2h to find a nicely way how to find duplicates in a list and how to remove them. Here is the simplest answer:

//Copy the string array with the filtered data of the analytics db into an list
// a list should be easier to use
List<string> list_filtered_data = new List<string>(analytics_db_filtered_data);

// Get distinct elements and convert into a list again.
List<string> distinct = list_filtered_data.Distinct().ToList();

The Output will look like this: Duplicated Elements will be removed in the new list called distinct!

That usually means that your friend does not have the Microsoft redistributable for Visual C++. I am of course assuming you are using VC++ and not MingW or another compiler. Since your friend does not have VS installed as well there is no guarantee he has the redist installed.

CREATE [TEMPORARY] TABLE [IF NOT EXISTS] tbl_name

[table_options]

Example :

CREATE TEMPORARY TABLE IF NOT EXISTS mytable
(id int(11) NOT NULL, PRIMARY KEY (id)) ENGINE=MyISAM;
INSERT IGNORE INTO mytable SELECT id FROM table WHERE xyz;

df = df.fillna('')

or just

df.fillna('', inplace=True)

This will fill na's (e.g. NaN's) with ''.

If you want to fill a single column, you can use:

df.column1 = df.column1.fillna('')

One can use df['column1'] instead of df.column1.

I figured out that this behaves like a mousedown event:

For SQL 2008 and newer, a more concise method, coding-wise, to detect index existence is by using the INDEXPROPERTY built-in function:

INDEXPROPERTY ( object_ID , index_or_statistics_name , property )  

The simplest usage is with the IndexID property:

If IndexProperty(Object_Id('MyTable'), 'MyIndex', 'IndexID') Is Null

If the index exists, the above will return its ID; if it doesn't, it will return NULL.

The closest I have been able to find is called 3taps. 3taps was sued by Craigslist with the result that "access to public data on a public website can be selectively censored by blacklisting certain viewers (i.e. competitors)", and thus states that "3taps will therefore access the very same data exclusively from public sources that retain open and equal access rights to public data".

The fastest way to check if a string contains another string is using indexOf:

}

If you aren't dynamically loading scripts or marking them as defer or async, then scripts are loaded in the order encountered in the page. It doesn't matter whether it's an external script or an inline script - they are executed in the order they are encountered in the page. Inline scripts that come after external scripts are held until all external scripts that came before them have loaded and run.

Async scripts (regardless of how they are specified as async) load and run in an unpredictable order. The browser loads them in parallel and it is free to run them in whatever order it wants.

There is no predictable order among multiple async things. If one needed a predictable order, then it would have to be coded in by registering for load notifications from the async scripts and manually sequencing javascript calls when the appropriate things are loaded.

When a script tag is inserted dynamically, how the execution order behaves will depend upon the browser. You can see how Firefox behaves in this reference article. In a nutshell, the newer versions of Firefox default a dynamically added script tag to async unless the script tag has been set otherwise.

A script tag with async may be run as soon as it is loaded. In fact, the browser may pause the parser from whatever else it was doing and run that script. So, it really can run at almost any time. If the script was cached, it might run almost immediately. If the script takes awhile to load, it might run after the parser is done. The one thing to remember with async is that it can run anytime and that time is not predictable.

A script tag with defer waits until the entire parser is done and then runs all scripts marked with defer in the order they were encountered. This allows you to mark several scripts that depend upon one another as defer. They will all get postponed until after the document parser is done, but they will execute in the order they were encountered preserving their dependencies. I think of defer like the scripts are dropped into a queue that will be processed after the parser is done. Technically, the browser may be downloading the scripts in the background at any time, but they won't execute or block the parser until after the parser is done parsing the page and parsing and running any inline scripts that are not marked defer or async.

Here's a quote from that article:

script-inserted scripts execute asynchronously in IE and WebKit, but synchronously in Opera and pre-4.0 Firefox.

The relevant part of the HTML5 spec (for newer compliant browsers) is here. There is a lot written in there about async behavior. Obviously, this spec doesn't apply to older browsers (or mal-conforming browsers) whose behavior you would probably have to test to determine.

A quote from the HTML5 spec:

Then, the first of the following options that describes the situation must be followed:

If the element has a src attribute, and the element has a defer attribute, and the element has been flagged as "parser-inserted", and the element does not have an async attribute The element must be added to the end of the list of scripts that will execute when the document has finished parsing associated with the Document of the parser that created the element.

The task that the networking task source places on the task queue once the fetching algorithm has completed must set the element's "ready to be parser-executed" flag. The parser will handle executing the script.

If the element has a src attribute, and the element has been flagged as "parser-inserted", and the element does not have an async attribute The element is the pending parsing-blocking script of the Document of the parser that created the element. (There can only be one such script per Document at a time.)

The task that the networking task source places on the task queue once the fetching algorithm has completed must set the element's "ready to be parser-executed" flag. The parser will handle executing the script.

If the element does not have a src attribute, and the element has been flagged as "parser-inserted", and the Document of the HTML parser or XML parser that created the script element has a style sheet that is blocking scripts The element is the pending parsing-blocking script of the Document of the parser that created the element. (There can only be one such script per Document at a time.)

Set the element's "ready to be parser-executed" flag. The parser will handle executing the script.

If the element has a src attribute, does not have an async attribute, and does not have the "force-async" flag set The element must be added to the end of the list of scripts that will execute in order as soon as possible associated with the Document of the script element at the time the prepare a script algorithm started.

The task that the networking task source places on the task queue once the fetching algorithm has completed must run the following steps:

If the element is not now the first element in the list of scripts that will execute in order as soon as possible to which it was added above, then mark the element as ready but abort these steps without executing the script yet.

Execution: Execute the script block corresponding to the first script element in this list of scripts that will execute in order as soon as possible.

Remove the first element from this list of scripts that will execute in order as soon as possible.

If this list of scripts that will execute in order as soon as possible is still not empty and the first entry has already been marked as ready, then jump back to the step labeled execution.

If the element has a src attribute The element must be added to the set of scripts that will execute as soon as possible of the Document of the script element at the time the prepare a script algorithm started.

The task that the networking task source places on the task queue once the fetching algorithm has completed must execute the script block and then remove the element from the set of scripts that will execute as soon as possible.

Otherwise The user agent must immediately execute the script block, even if other scripts are already executing.

What about Javascript module scripts, type="module"?

Javascript now has support for module loading with syntax like this:

<script type="module">
  import {addTextToBody} from './utils.mjs';

  addTextToBody('Modules are pretty cool.');
</script>

Or, with src attribute:

<script type="module" src="http://somedomain.com/somescript.mjs">
</script>

All scripts with type="module" are automatically given the defer attribute. This downloads them in parallel (if not inline) with other loading of the page and then runs them in order, but after the parser is done.

Module scripts can also be given the async attribute which will run inline module scripts as soon as possible, not waiting until the parser is done and not waiting to run the async script in any particular order relative to other scripts.

There's a pretty useful timeline chart that shows fetch and execution of different combinations of scripts, including module scripts here in this article: Javascript Module Loading.

I know that this isn't what you asked for but LINQPad is a really great tool to teach yourself LINQ (and it's free :o).

When time isn't critical, I have been using it for the last week or so instead or a query window in SQL Server and my LINQ skills are getting better and better.

It's also a nice little code snippet tool. Its only downside is that the free version doesn't have IntelliSense.

Based on answer by @Cici I give here a more generic solution:

=SUM(INDIRECT(CONCATENATE(B1,C1)):INDIRECT(CONCATENATE(B2,C2)))

In Italian version of Excel:

=SOMMA(INDIRETTO(CONCATENA(B1;C1)):INDIRETTO(CONCATENA(B2;C2)))

Where B1-C2 cells hold these values:

• A, 1
• A, 5

You can change these valuese to change the final range at wish.

Splitting the formula in parts:

• SUM(INDIRECT(CONCATENATE(B1,C1)):INDIRECT(CONCATENATE(B2,C2)))
• CONCATENATE(B1,C1) - result is A1
• INDIRECT(CONCATENATE(B1,C1)) - result is reference to A1

Hence:

=SUM(INDIRECT(CONCATENATE(B1,C1)):INDIRECT(CONCATENATE(B2,C2)))

results in

=SUM(A1:A5)

I'll write down here a couple of SEO keywords for Italian users:

• come creare dinamicamente l'indirizzo di un intervallo in excel
• formula per definire un intervallo di celle in excel.

Con la formula indicata qui sopra basta scrivere nelle caselle da B1 a C2 gli estremi dell'intervallo per vedelo cambiare dentro la formula stessa.

int[] b = new int[3];
Array.Copy(a, 1, b, 0, 3);

• a = source array
• 1 = start index in source array
• b = destination array
• 0 = start index in destination array
• 3 = elements to copy

You may be interested in unique set of objects based on one of the keys:

let array = 
[
    {"name":"Joe", "age":17}, 
    {"name":"Bob", "age":17}, 
    {"name":"Carl", "age": 35}
]
let unq_objs = [...new Map(array.map(o =>[o["age"], o])).values()];
console.log(unq_objs)
//result
[{name: "Bob", age: 17},
{name: "Carl", age: 35}]

Another R package for aggregating multiple regression models into LaTeX tables is texreg.

The reason normalization is needed is because if you look at how an adaptive step proceeds in one place in the domain of the function, and you just simply transport the problem to the equivalent of the same step translated by some large value in some direction in the domain, then you get different results. It boils down to the question of adapting a linear piece to a data point. How much should the piece move without turning and how much should it turn in response to that one training point? It makes no sense to have a changed adaptation procedure in different parts of the domain! So normalization is required to reduce the difference in the training result. I haven't got this written up, but you can just look at the math for a simple linear function and how it is trained by one training point in two different places. This problem may have been corrected in some places, but I am not familiar with them. In ALNs, the problem has been corrected and I can send you a paper if you write to wwarmstrong AT shaw.ca

First: I assumed you already have Python 2.7 or 3.4 installed.

1: In the Control Panel, open the System option (alternately, you can right-click on My Computer and select Properties). Select the “Advanced system settings” link.

2. In the System Properties dialog, click “Environment Variables”.

3. In the Environment Variables dialog, click the New button underneath the “System variables” section.

4. if someone is there that above is not working, then kindly append to your PATH with the C:\Python27 then it should surely work. C:\Python27\Scripts

5. Run this command (Windows cmd terminal): pip install virtualenv

6. If you already have pip, you can upgrade them by running:

   pip install --upgrade pip setuptools

7. Create your project. Then, run virtualenv flask

Your task declaration is incorrectly combining the Copy task type and project.copy method, resulting in a task that has nothing to copy and thus never runs. Besides, Copy isn't the right choice for renaming a directory. There is no Gradle API for renaming, but a bit of Groovy code (leveraging Java's File API) will do. Assuming Project1 is the project directory:

task renABCToXYZ {     doLast {         file("ABC").renameTo(file("XYZ"))     } } 

Looking at the bigger picture, it's probably better to add the renaming logic (i.e. the doLast task action) to the task that produces ABC.

The reason is that modprobe looks into /lib/modules/$(uname -r) for the modules and therefore won't work with local file path. That's one of differences between modprobe and insmod.

Consider a binary tree whose nodes are drawn in a tree fashion. Now start numbering the nodes from top to bottom and left to right. A complete tree has these properties:

If n has children then all nodes numbered less than n have two children.

If n has one child it must be the left child and all nodes less than n have two children. In addition no node numbered greater than n has children.

If n has no children then no node numbered greater than n has children.

A complete binary tree can be used to represent a heap. It can be easily represented in contiguous memory with no gaps (i.e. all array elements are used save for any space that may exist at the end).

I know the OP was asking about doing the export from the command line, but just in case this is helpful to anyone else out there...

You could just let Eclipse (plus one of the plugins discussed here) do the work for you.

Obviously, downloading Eclipse just for doing a single export is overkill, but if you are already using it for development, you can also do an svn export simply from your IDE's context menu when browsing an SVN repository.

Advantages:

• easier for those not so familiar with using SVN at the command-line level (but you can learn about what happens at the command-line level by looking at the SVN console with a range of commands)
• you'd already have your SVN details set up and wouldn't have to worry about authenticating, etc.
• you don't have to worry about mistyping the URL, or remembering the order of parameters
• you can specify in a dialog which directory you'd like to export to
• you can specify in a dialog whether you'd like to export from TRUNK/HEAD or use a specific revision

Just add this one-line class in your CSS, and use the bootstrap label component.

.label-as-badge {
    border-radius: 1em;
}

Compare this label and badge side by side:

<span class="label label-default label-as-badge">hello</span>
<span class="badge">world</span>

They appear the same. But in the CSS, label uses em so it scales nicely, and it still has all the "-color" classes. So the label will scale to bigger font sizes better, and can be colored with label-success, label-warning, etc. Here are two examples:

<span class="label label-success label-as-badge">Yay! Rah!</span>

Or where things are bigger:

<div style="font-size: 36px"><!-- pretend an enclosing class has big font size -->
    <span class="label label-success label-as-badge">Yay! Rah!</span>
</div>

11/16/2015: Looking at how we'll do this in Bootstrap 4

Looks like .badge classes are completely gone. But there's a built-in .label-pill class (here) that looks like what we want.

.label-pill {
  padding-right: .6em;
  padding-left: .6em;
  border-radius: 10rem;
}

In use it looks like this:

<span class="label label-pill label-default">Default</span>
<span class="label label-pill label-primary">Primary</span>
<span class="label label-pill label-success">Success</span>
<span class="label label-pill label-info">Info</span>
<span class="label label-pill label-warning">Warning</span>
<span class="label label-pill label-danger">Danger</span>

11/04/2014: Here's an update on why cross-pollinating alert classes with .badge is not so great. I think this picture sums it up:

Those alert classes were not designed to go with badges. It renders them with a "hint" of the intended colors, but in the end consistency is thrown out the window and readability is questionable. Those alert-hacked badges are not visually cohesive.

The .label-as-badge solution is only extending the bootstrap design. We are keeping intact all the decision making made by the bootstrap designers, namely the consideration they gave for readability and cohesion across all the possible colors, as well as the color choices themselves. The .label-as-badge class only adds rounded corners, and nothing else. There are no color definitions introduced. Thus, a single line of CSS.

Yep, it is easier to just hack away and drop in those .alert-xxxxx classes -- you don't have to add any lines of CSS. Or you could care more about the little things and add one line.

I am the original poster and I accepted the above answer by DGH without having first used it in the code.

Once I did use I realised that it needed a little tweaking to actually do what I needed it to do (to be fair to DGH he/she did say "or something similar" !).

I thought it was worth posting the tweak here for the benefit of others:

    try:
        a = Application("abcdef", "")
    except pySourceAidExceptions.PathIsNotAValidOne:
        pass
    except:
        self.assertTrue(False)

What I was attempting to do here was to ensure that if an attempt was made to instantiate an Application object with a second argument of spaces the pySourceAidExceptions.PathIsNotAValidOne would be raised.

I believe that using the above code (based heavily on DGH's answer) will do that.

I tried looking for an event as described above, but when the request function fires it doesn't seem to be available. I used this.element.attr("id") to get the element's ID instead, and it seems to work fine.

BOTHER appears to be available from <asm/termios.h> on Linux. Pulling the definition from there is going to be wildly non-portable, but I assume this API is non-portable anyway, so it's probably no big loss.

The value content attribute gives the default value of the input element.

To set the default value of an input element, use the value attribute.

<input type="text" value="default value">

The only example I can think of where it makes sense to call System.gc() is when profiling an application to search for possible memory leaks. I believe the profilers call this method just before taking a memory snapshot.

Context is stored at the application level scope where as request is stored at page level i.e to say

Web Container brings up the applications one by one and run them inside its JVM. It stores a singleton object in its jvm where it registers anyobject that is put inside it.This singleton is shared across all applications running inside it as it is stored inside the JVM of the container itself.

However for requests, the container creates a request object that is filled with data from request and is passed along from one thread to the other (each thread is a new request that is coming to the server), also request is passed to the threads of same application.

Even simple one is using the String ReplaceAll function itself. You can write it as

StringBuilder sb = new StringBuilder("Hi there, are you there?")
System.out.println(Pattern.compile("there").matcher(sb).replaceAll("niru"));

As of April 2018, Chrome (along with several other major browsers) now require the muted attribute too.

Therefore, you should use

<video width="320" height="240" autoplay loop muted>
  <source src="movie.mp4" type="video/mp4" />
</video>
