You can write your For loop to individually store dataframes from a list:

allocation = list()

for(i in 1:length(allocation)){
    write.csv(data.frame(allocation[[i]]), file = paste0(path, names(allocation)[i], '.csv'))
}

Using Request.Url.Host is appropriate - it's how you retrieve the value of the HTTP Host: header, which specifies which hostname (domain name) the UA (browser) wants, as the Resource-path part of the HTTP request does not include the hostname.

Note that localhost:5858 is not a domain name, it is an endpoint specifier, also known as an "authority", which includes the hostname and TCP port number. This is retrieved by accessing Request.Uri.Authority.

Furthermore, it is not valid to get somedomain.com from www.somedomain.com because a webserver could be configured to serve a different site for www.somedomain.com compared to somedomain.com, however if you are sure this is valid in your case then you'll need to manually parse the hostname, though using String.Split('.') works in a pinch.

Note that webserver (IIS) configuration is distinct from ASP.NET's configuration, and that ASP.NET is actually completely ignorant of the HTTP binding configuration of the websites and web-applications that it runs under. The fact that both IIS and ASP.NET share the same configuration files (web.config) is a red-herring.

It would be inappropriate for it to be part of the setter - it's not like you're really setting the whole list of strings - you're just trying to add one.

There are a few options:

• Put AddSubheading and AddContent methods in your class, and only expose read-only versions of the lists
• Expose the mutable lists just with getters, and let callers add to them
• Give up all hope of encapsulation, and just make them read/write properties

In the second case, your code can be just:

public class Section
{
    public String Head { get; set; }
    private readonly List<string> _subHead = new List<string>();
    private readonly List<string> _content = new List<string>();

    // Note: fix to case to conform with .NET naming conventions
    public IList<string> SubHead { get { return _subHead; } }
    public IList<string> Content { get { return _content; } }
}

This is reasonably pragmatic code, although it does mean that callers can mutate your collections any way they want, which might not be ideal. The first approach keeps the most control (only your code ever sees the mutable list) but may not be as convenient for callers.

Making the setter of a collection type actually just add a single element to an existing collection is neither feasible nor would it be pleasant, so I'd advise you to just give up on that idea.

@AnandaMahto has addressed why you're getting these results and provided the clearest way to get what you want. But another option would be to use identical instead of ==.

test$ID <- ifelse(is.na(test$time) | sapply(as.character(test$type), identical, "A"), NA, "1")

Or use isTRUE:

test$ID <- ifelse(is.na(test$time) | Vectorize(isTRUE)(test$type == "A"), NA, "1")

Declare them internal, and then use the InternalsVisibleToAttribute to allow your unit test assembly to see them.

Your strings are JSON formatted, so you will need to parse it into a object. For that you can use JSON.NET.

Here is an example on how to parse a JSON string into a dynamic object:

string source = "{\r\n   \"id\": \"100000280905615\", \r\n \"name\": \"Jerard Jones\",  \r\n   \"first_name\": \"Jerard\", \r\n   \"last_name\": \"Jones\", \r\n   \"link\": \"https://www.facebook.com/Jerard.Jones\", \r\n   \"username\": \"Jerard.Jones\", \r\n   \"gender\": \"female\", \r\n   \"locale\": \"en_US\"\r\n}";
dynamic data = JObject.Parse(source);
Console.WriteLine(data.id);
Console.WriteLine(data.first_name);
Console.WriteLine(data.last_name);
Console.WriteLine(data.gender);
Console.WriteLine(data.locale);

Happy coding!

In short, no. However, you need to keep in mind that certain client access CRUD operations require it. For future proofing, I tend to always utilize primary keys.

This is more readable for me

awk '{if ($2 ~ /findtext/) print $3}' <infile>

From websites, using Firefox, I use the CopyPlainText extension.

I wouldn't advise you to do this but on my personal computer I disabled the firewall so that maven could get the required plugins.

Let me add an example here:

I'm trying to build Alluxio on windows platform and got the same issue, it's because the pom.xml contains below step:

      <plugin>
        <artifactId>exec-maven-plugin</artifactId>
        <groupId>org.codehaus.mojo</groupId>
        <inherited>false</inherited>
        <executions>
          <execution>
            <id>Check that there are no Windows line endings</id>
            <phase>compile</phase>
            <goals>
              <goal>exec</goal>
            </goals>
            <configuration>
              <executable>${build.path}/style/check_no_windows_line_endings.sh</executable>
            </configuration>
          </execution>
        </executions>
      </plugin>

The .sh file is not executable on windows so the error throws.

Comment it out if you do want build Alluxio on windows.

I'm using zsh on my Mac, what worked for me is at first install pipenv

pip3 install --user pipenv

Then I changed the PATH in the ~/.zshrc

vi ~/.zshrc

In the editor press i to insert your text:

export PATH="/Users/yourUser/Library/Python/3.9/bin:$PATH"

Press esc and then write :wq! Close the terminal and re-open it. And finally write pipenv

This way worked for me using macOS BigSur 11.1

Java 8 introduced a nice computeIfAbsent default method to Map interface which stores lazy-computed value and so doesn't break map contract:

Map<Key, Graph> map = new HashMap<>();
map.computeIfAbsent(aKey, key -> createExpensiveGraph(key));

Origin: http://blog.javabien.net/2014/02/20/loadingcache-in-java-8-without-guava/

Disclamer: This answer doesn't match exactly what OP asked but may be handy in some cases matching question's title when keys number is limited and caching of different values would be profitable. It shouldn't be used in opposite case with plenty of keys and same default value as this would needlessly waste memory.

One can also use the Flask Debug Toolbar extension to get more detailed information embedded in rendered pages.

from flask import Flask
from flask_debugtoolbar import DebugToolbarExtension
import logging

app = Flask(__name__)
app.debug = True
app.secret_key = 'development key'

toolbar = DebugToolbarExtension(app)

@app.route('/')
def index():
    logging.warning("See this message in Flask Debug Toolbar!")
    return "<html><body></body></html>"

Start the application as follows:

FLASK_APP=main.py FLASK_DEBUG=1 flask run

try

date.innerHTML= date.innerHTML.replace(/^(..)\//,'<span>$1</span></br>')

<div id="date">23/05/2013</div>

Thats really insane, i tried everything, synced with Gradle files, invalidated and restarted android studio. Still the problem persisted. Last resort was deleting .idea/libraries folder and it worked as charm.

You can get the scrollbar size and then apply a margin to the container.

Something like this:

var checkScrollBars = function(){
    var b = $('body');
    var normalw = 0;
    var scrollw = 0;
    if(b.prop('scrollHeight')>b.height()){
        normalw = window.innerWidth;
        scrollw = normalw - b.width();
        $('#container').css({marginRight:'-'+scrollw+'px'});
    }
}

CSS for remove the h-scrollbar:

body{
    overflow-x:hidden;
}

Try to take a look at this: http://jsfiddle.net/NQAzt/

var: Declare a variable, value initialization optional.

let: Declare a local variable with block scope.

const: Declare a read-only named constant.

Ex:

var a;
a = 1;
a = 2;//re-initialize possible
var a = 3;//re-declare
console.log(a);//3

let b;
b = 5;
b = 6;//re-initiliaze possible
// let b = 7; //re-declare not possible
console.log(b);

// const c;
// c = 9;   //initialization and declaration at same place
const c = 9;
// const c = 9;// re-declare and initialization is not possible
console.log(c);//9
// NOTE: Constants can be declared with uppercase or lowercase, but a common
// convention is to use all-uppercase letters.

I would use Swing for a couple of reasons.

• It has been around longer and has had more development effort applied to it. Hence it is likely more feature complete and (maybe) has fewer bugs.

• There is lots of documentation and other guidance on producing performant applications.

• It seems like changes to Swing propagate to all platforms simultaneously while changes to SWT seem to appear on Windows first, then Linux.

If you want to build a very feature-rich application, you might want to check out the NetBeans RCP (Rich Client Platform). There's a learning curve, but you can put together nice applications quickly with a little practice. I don't have enough experience with the Eclipse platform to make a valid judgment.

If you don't want to use the entire RCP, NetBeans also has many useful components that can be pulled out and used independently.

One other word of advice, look into different layout managers. They tripped me up for a long time when I was learning. Some of the best aren't even in the standard library. The MigLayout (for both Swing and SWT) and JGoodies Forms tools are two of the best in my opinion.

For Unix users, mail() is actually using Sendmail command to send email. Instead of modifying the application, you can change the environment. msmtp is an SMTP client with Sendmail compatible CLI syntax which means it can be used in place of Sendmail. It only requires a small change to your php.ini.

sendmail_path = "/usr/bin/msmtp -C /path/to/your/config -t"

Then even the lowly mail() function can work with SMTP goodness. It is super useful if you're trying to connect an existing application to mail services like sendgrid or mandrill without modifying the application.

Now a day use of gravity start is best choise:

android:gravity="start"

For EditText (textarea):

<EditText
    android:id="@+id/EditText02"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:lines="5"
    android:gravity="start"
    android:inputType="textMultiLine"
/>

Use

Console.WriteLine(String.Format("  {0:G17}", i));

That will give you all the 17 digits it have. By default, a Double value contains 15 decimal digits of precision, although a maximum of 17 digits is maintained internally. {0:R} will not always give you 17 digits, it will give 15 if the number can be represented with that precision.

which returns 15 digits if the number can be represented with that precision or 17 digits if the number can only be represented with maximum precision. There isn't any thing you can to do to make the the double return more digits that is the way it's implemented. If you don't like it do a new double class yourself...

.NET's double cant store any more digits than 17 so you cant see 6.89999999999999946709 in the debugger you would see 6.8999999999999995. Please provide an image to prove us wrong.

see here under 3.5.3(shell parameter expansion)

so in your case

${VARIABLE:-default}

The return value of os.system is OS-dependant.

On Unix, the return value is a 16-bit number that contains two different pieces of information. From the documentation:

a 16-bit number, whose low byte is the signal number that killed the process, and whose high byte is the exit status (if the signal number is zero)

So if the signal number (low byte) is 0, it would, in theory, be safe to shift the result by 8 bits (result >> 8) to get the error code. The function os.WEXITSTATUS does exactly this. If the error code is 0, that usually means that the process exited without errors.

On Windows, the documentation specifies that the return value of os.system is shell-dependant. If the shell is cmd.exe (the default one), the value is the return code of the process. Again, 0 would mean that there weren't errors.

For others error codes:

• on Linux
• on Windows

Use IDA Pro and the Decompiler.

Here's an option that stays as true I could make it to the OP's requirement to be able to switch on type. If you squint hard enough it almost looks like a real switch statement.

The calling code looks like this:

var @switch = this.Switch(new []
{
    this.Case<WebControl>(x => { /* WebControl code here */ }),
    this.Case<TextBox>(x => { /* TextBox code here */ }),
    this.Case<ComboBox>(x => { /* ComboBox code here */ }),
});

@switch(obj);

The x in each lambda above is strongly-typed. No casting required.

And to make this magic work you need these two methods:

private Action<object> Switch(params Func<object, Action>[] tests)
{
    return o =>
    {
        var @case = tests
            .Select(f => f(o))
            .FirstOrDefault(a => a != null);

        if (@case != null)
        {
            @case();
        }
    };
}

private Func<object, Action> Case<T>(Action<T> action)
{
    return o => o is T ? (Action)(() => action((T)o)) : (Action)null;
}

Almost brings tears to your eyes, right?

Nonetheless, it works. Enjoy.

Install the Eclipse Metrics Plugin. To create a HTML report (with optional XML and CSV) right-click a project -> Export -> Other -> Metrics.

You can adjust the Lines of Code metrics by ignoring blank and comment-only lines or exclude Javadoc if you want. To do this check the tab at Preferences -> Metrics -> LoC.

That's it. There is no special option to exclude curly braces {}.

The plugin offers an alternative metric to LoC called Number of Statements. This is what the author has to say about it:

This metric represents the number of statements in a method. I consider it a more robust measure than Lines of Code since the latter is fragile with respect to different formatting conventions.

Edit:

After you clarified your question, I understand that you need a view for real-time metrics violations, like compiler warnings or errors. You also need a reporting functionality to create reports for your boss. The plugin I described above is for reporting because you have to export the metrics when you want to see them.

You have to use implicitly unwrapped optionals so that Swift can cope with circular dependencies (parent <-> child of the UI components in this case) during the initialization phase.

@IBOutlet var imgBook: UIImageView!
@IBOutlet var titleBook: UILabel!
@IBOutlet var pageBook: UILabel!

Read this doc, they explain it all nicely.

I use the blow function in my GeneralUtils class, check it may be useful

    public String getFieldType(Object o) {
    if (o == null) {
        return "Unable to identify the class name";
    }
    return o.getClass().getName();
}

Use the map method:

var a = [1, 2, 3]_x000D_
var b = ['a', 'b', 'c']_x000D_
_x000D_
var c = a.map(function(e, i) {_x000D_
  return [e, b[i]];_x000D_
});_x000D_
_x000D_
console.log(c)

DEMO

An iframe is used to embed another document inside a html page.

If the form is to be submitted to an iframe within the form page, then it can be easily acheived using the target attribute of the tag.

Set the target attribute of the form to the name of the iframe tag.

<form action="action" method="post" target="output_frame">
    <!-- input elements here --> 
</form>
<iframe name="output_frame" src="" id="output_frame" width="XX" height="YY">
</iframe>           

Advanced iframe target use
This property can also be used to produce an ajax like experience, especially in cases like file upload, in which case where it becomes mandatory to submit the form, in order to upload the files

The iframe can be set to a width and height of 0, and the form can be submitted with the target set to the iframe, and a loading dialog opened before submitting the form. So, it mocks a ajax control as the control still remains on the input form jsp, with the loading dialog open.

Exmaple

<script>
$( "#uploadDialog" ).dialog({ autoOpen: false, modal: true, closeOnEscape: false,                 
            open: function(event, ui) { jQuery('.ui-dialog-titlebar-close').hide(); } });

function startUpload()
{            
    $("#uploadDialog").dialog("open");
}

function stopUpload()
{            
    $("#uploadDialog").dialog("close");
}
</script>

<div id="uploadDialog" title="Please Wait!!!">
            <center>
            <img src="/imagePath/loading.gif" width="100" height="100"/>
            <br/>
            Loading Details...
            </center>
 </div>

<FORM  ENCTYPE="multipart/form-data" ACTION="Action" METHOD="POST" target="upload_target" onsubmit="startUpload()"> 
<!-- input file elements here--> 
</FORM>

<iframe id="upload_target" name="upload_target" src="#" style="width:0;height:0;border:0px solid #fff;" onload="stopUpload()">   
        </iframe>

Here are two methods to get more than 1 column in a scalar subquery (or inline subquery) and querying the lookup table only once. This is a bit convoluted but can be the very efficient in some special cases.

1. You can use concatenation to get several columns at once:

   SELECT x, 
          regexp_substr(yz, '[^^]+', 1, 1) y,
          regexp_substr(yz, '[^^]+', 1, 2) z
     FROM (SELECT a.x,
                  (SELECT b.y || '^' || b.z yz
                     FROM b
                    WHERE b.v = a.v)
                     yz
             FROM a)
   

   You would need to make sure that no column in the list contain the separator character.

2. You could also use SQL objects:

   CREATE OR REPLACE TYPE b_obj AS OBJECT (y number, z number);
   
   SELECT x, 
          v.yz.y y,
          v.yz.z z
     FROM (SELECT a.x,
                  (SELECT b_obj(y, z) yz
                     FROM b
                    WHERE b.v = a.v)
                     yz
             FROM a) v
   

Unfortunately: NO.

We're all eagerly awaiting the Java support for extension methods

GAC = Global Assembly Cache

Let's break it down:

• global - applies to the entire machine
• assembly - what .NET calls its code-libraries (DLLs)
• cache - a place to store things for faster/common access

So the GAC must be a place to store code libraries so they're accessible to all applications running on the machine.

$_ is the active object in the current pipeline. You've started a new pipeline with $FOLDLIST | ... so $_ represents the objects in that array that are passed down the pipeline. You should stash the FileInfo object from the first pipeline in a variable and then reference that variable later e.g.:

write-host $NEWN.Length
$file = $_
...
Move-Item $file.Name $DPATH

I think the current answers are neglecting to highlight the actual important and significant differences and what that means for the intended usage. While they might both work in certain situations because the implementer built in support for both, they have different usage scenarios. Both can annotate properties and methods but here are some important differences:

DisplayAttribute

• defined in the System.ComponentModel.DataAnnotations namespace in the System.ComponentModel.DataAnnotations.dll assembly
• can be used on parameters and fields
• lets you set additional properties like Description or ShortName
• can be localized with resources

DisplayNameAttribute

• DisplayName is in the System.ComponentModel namespace in System.dll
• can be used on classes and events
• cannot be localized with resources

The assembly and namespace speaks to the intended usage and localization support is the big kicker. DisplayNameAttribute has been around since .NET 2 and seems to have been intended more for naming of developer components and properties in the legacy property grid, not so much for things visible to end users that may need localization and such.

DisplayAttribute was introduced later in .NET 4 and seems to be designed specifically for labeling members of data classes that will be end-user visible, so it is more suitable for DTOs, entities, and other things of that sort. I find it rather unfortunate that they limited it so it can't be used on classes though.

EDIT: Looks like latest .NET Core source allows DisplayAttribute to be used on classes now as well.

The fact that a HTTPS request becomes HTTP when you tried to construct the URL on server side indicates that you might have a proxy/load balancer (nginx, pound, etc.) offloading SSL encryption in front and forward to your back end service in plain HTTP.

If that's case, check,

1. whether your proxy has been set up to forward headers correctly (Host, X-forwarded-proto, X-forwarded-for, etc).
2. whether your service container (E.g. Tomcat) is set up to recognize the proxy in front. For example, Tomcat requires adding secure="true" scheme="https" proxyPort="443" attributes to its Connector
3. whether your code, or service container is processing the headers correctly. For example, Tomcat automatically replaces scheme, remoteAddr, etc. values when you add RemoteIpValve to its Engine. (see Configuration guide, JavaDoc) so you don't have to process these headers in your code manually.

Incorrect proxy header values could result in incorrect output when request.getRequestURI() or request.getRequestURL() attempts to construct the originating URL.

File SqlStudio.bin actually contains binary serialized data of type "Microsoft.SqlServer.Management.UserSettings.SqlStudio".

Using BinaryFormatter class you can write simple .NET application in order to edit file content.

According to this post, there is a considerably large performance benefit on MySQL 5.7 when using utf8mb4_general_ci in stead of utf8mb4_unicode_ci: https://www.percona.com/blog/2019/02/27/charset-and-collation-settings-impact-on-mysql-performance/

You should do ex.StackTrace instead of ex.ToString()

Given you use JQuery, you can do something like below :

HTML

<form id="myform">
    syn<input type="checkbox" name="checkfield" id="g01-01"  onclick="doalert()"/>
</form>

JS

function doalert() {
  if ($("#g01-01").is(":checked")) {
    alert ("hi");
  } else {
    alert ("bye");
  }
}

By default, Maven will always look in the official Maven repository, which is http://repo1.maven.org.

When Maven tries to build a project, it will look in your local repository (by default ~/.m2/repository but you can configure it by changing the <localRepository> value in your ~/.m2/settings.xml) to find any dependency, plugin or report defined in your pom.xml. If the adequate artifact is not found in your local repository, it will look in all external repositories configured, starting with the default one, http://repo1.maven.org.

You can configure Maven to avoid this default repository by setting a mirror in your settings.xml file:

<mirrors>
    <mirror>
        <id>repoMirror</id>
        <name>Our mirror for Maven repository</name>
        <url>http://the/server/</url>
        <mirrorOf>*</mirrorOf>
    </mirror>
</mirrors>

This way, instead of contacting http://repo1.maven.org, Maven will contact your entreprise repository (http://the/server in this example).

If you want to add another repository, you can define a new one in your settings.xml file:

<profiles>
    <profile>
        <activation>
            <activeByDefault>true</activeByDefault>
        </activation>
        <repositories>
            <repository>
                <id>foo.bar</id>
                <releases>
                    <enabled>true</enabled>
                </releases>
                <snapshots>
                    <enabled>true</enabled>
                </snapshots>
                <url>http://new/repository/server</url>
            </repository>
        </repositories>

You can see the complete settings.xml model here.

Concerning the clean process, you can ask Maven to run it offline. In this case, Maven will not try to reach any external repositories:

mvn -o clean 

Loading an excel file without explicitly naming a sheet but instead giving the number of the sheet order (often one will simply load the first sheet) goes like:

import pandas as pd
myexcel = pd.ExcelFile("C:/filename.xlsx")
myexcel = myexcel.parse(myexcel.sheet_names[0])

Since .sheet_names returns a list of sheet names, it is easy to load one or more sheets by simply calling the list element(s).

Using the Java 8 Streams API.

List<Value> values = map.values().stream().collect(Collectors.toList());

Why don't you use the Modulus Operator?

Try this:

while ($s % 6 != 0) $s++;

Or is this what you meant?

<?

 $s= <some_number>;
 $k= $s % 6;

 if($k !=0)    $s=$s+6-$k;
?>

jQuery does only make some regexp checking before calling the native browser method window.JSON.parse(). If that is not available, it uses eval() or more exactly new Function() to create a Javascript object.

The opposite of JSON.parse() is JSON.stringify() which serializes a Javascript object into a string. jQuery does not have functionality of its own for that, you have to use the browser built-in version or json2.js from http://www.json.org

JSON.stringify() is available in all major browsers, but to be compatible with older browsers you still need that fallback.

Here is one neat way with easy to understand algorithm.

import copy

nums = [2,3,4,5]
subsets = [[]]

for n in nums:
    prev = copy.deepcopy(subsets)
    [k.append(n) for k in subsets]
    subsets.extend(prev)

print(subsets) 
print(len(subsets))

# [[2, 3, 4, 5], [3, 4, 5], [2, 4, 5], [4, 5], [2, 3, 5], [3, 5], [2, 5], [5], 
# [2, 3, 4], [3, 4], [2, 4], [4], [2, 3], [3], [2], []]

# 16 (2^len(nums))

You can do it this way:

=IF(E9>21,"Text 1",IF(AND(E9>=5,E9<=21),"Test 2","Text 3"))

Note I assume you meant >= and <= here since your description skipped the values 5 and 21, but you can adjust these inequalities as needed.

Or you can do it this way:

=IF(E9>21,"Text 1",IF(E9<5,"Text 3","Text 2"))

If you're getting this, you may have forgotten to put #include <thread> at the beginning of your file. OP's signature seems like it should work.

You can simply press Ctrl+F5 instead of F5 to run the built code. Then it will prompt you to press any key to continue. Or you can use this line -> system("pause"); at the end of the code to make it wait until you press any key.

However, if you use the above line, system("pause"); and press Ctrl+F5 to run, it will prompt you twice!

Simple, standard library only. Gives timezone-aware datetime, unlike datetime.utcnow().

If you add a new line of text at the end of the existing file which does not already have a newline character at the end, the diff will show the old last line as having been modified, even though conceptually it wasn’t.

This is at least one good reason to add a newline character at the end.

Example

A file contains:

A() {
    // do something
}

Hexdump:

00000000: 4128 2920 7b0a 2020 2020 2f2f 2064 6f20  A() {.    // do 
00000010: 736f 6d65 7468 696e 670a 7d              something.}

You now edit it to

A() {
    // do something
}
// Useful comment

Hexdump:

00000000: 4128 2920 7b0a 2020 2020 2f2f 2064 6f20  A() {.    // do 
00000010: 736f 6d65 7468 696e 670a 7d0a 2f2f 2055  something.}.// U
00000020: 7365 6675 6c20 636f 6d6d 656e 742e 0a    seful comment..

The git diff will show:

-}
\ No newline at end of file
+}
+// Useful comment.

In other words, it shows a larger diff than conceptually occurred. It shows that you deleted the line } and added the line }\n. This is, in fact, what happened, but it’s not what conceptually happened, so it can be confusing.

This is pure speculation on my part, but I suppose that they may use an influence map data structure overlaying the directed map in order to narrow the search domain. This would allow the search algorithm to direct the path to major routes when the desired trip is long.

Given that this is a Google app, it's also reasonable to suppose that a lot of the magic is done via extensive caching. :) I wouldn't be surprised if caching the top 5% most common Google Map route requests allowed for a large chunk (20%? 50%?) of requests to be answered by a simple look-up.

Use below script

Object[] myNum = {10, 20, 30, 40};
List<Object> newArr = new ArrayList<>(Arrays.asList(myNum));

This is the HTML only way:

<body>
<a name="top"></a>
foo content
foo bottom of page
<a href="#top">Back to Top</a>
</body>

There are quite a few other alternatives using jquery and jscript though which offer additional effects. It really just depends on what you are looking for.

Just try below script:

Below code works only if studentid column datatype is varchar

SELECT * FROM STUDENTS WHERE STUDENTID like '%Searchstring%'

Put this in your Application.java file

@ComponentScan(basePackages={"com.nervy.dialer"})
@EntityScan(basePackages="domain")

echo "{$test}y";

You can use braces to remove ambiguity when interpolating variables directly in strings.

Also, this doesn't work with single quotes. So:

echo '{$test}y';

will output

{$test}y

For future reference to anyone here having difficulty, if you are adding the checkboxes dynamically, the correct accepted answer above will not work. You'll need to leverage event delegation which allows a parent node to capture bubbled events from a specific descendant and issue a callback.

// $(<parent>).on('<event>', '<child>', callback);
$(document).on('change', '.checkbox', function() {
    if(this.checked) {
      // checkbox is checked
    }
});

Note that it's almost always unnecessary to use document for the parent selector. Instead choose a more specific parent node to prevent propagating the event up too many levels.

The example below displays how the events of dynamically added dom nodes do not trigger previously defined listeners.

$postList = $('#post-list');_x000D_
_x000D_
$postList.find('h1').on('click', onH1Clicked);_x000D_
_x000D_
function onH1Clicked() {_x000D_
  alert($(this).text());_x000D_
}_x000D_
_x000D_
// simulate added content_x000D_
var title = 2;_x000D_
_x000D_
function generateRandomArticle(title) {_x000D_
  $postList.append('<article class="post"><h1>Title ' + title + '</h1></article>');_x000D_
}_x000D_
_x000D_
setTimeout(generateRandomArticle.bind(null, ++title), 1000);_x000D_
setTimeout(generateRandomArticle.bind(null, ++title), 5000);_x000D_
setTimeout(generateRandomArticle.bind(null, ++title), 10000);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<section id="post-list" class="list post-list">_x000D_
  <article class="post">_x000D_
    <h1>Title 1</h1>_x000D_
  </article>_x000D_
  <article class="post">_x000D_
    <h1>Title 2</h1>_x000D_
  </article>_x000D_
</section>

While this example displays the usage of event delegation to capture events for a specific node (h1 in this case), and issue a callback for such events.

$postList = $('#post-list');_x000D_
_x000D_
$postList.on('click', 'h1', onH1Clicked);_x000D_
_x000D_
function onH1Clicked() {_x000D_
  alert($(this).text());_x000D_
}_x000D_
_x000D_
// simulate added content_x000D_
var title = 2;_x000D_
_x000D_
function generateRandomArticle(title) {_x000D_
  $postList.append('<article class="post"><h1>Title ' + title + '</h1></article>');_x000D_
}_x000D_
_x000D_
setTimeout(generateRandomArticle.bind(null, ++title), 1000); setTimeout(generateRandomArticle.bind(null, ++title), 5000); setTimeout(generateRandomArticle.bind(null, ++title), 10000);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_

I know that is a old question, but...

You can also use this in your class:

@Autowired
private HttpServletRequest context;

And this will provide the current instance of HttpServletRequest for you use on your method.

Ok the first issue with the div tag was easy enough: I just added a style="display:none;" to it and then before showing the dialog I added this in my dialog script:

$("#dialog").css("display", "inherit");

But for the post version I'm still out of luck.

Try this awk

awk -F, '{$0=$3}1' file
column3

• , Divide fields by ,
• $0=$3 Set the line to only field 3
• 1 Print all out. (explained here)

This could also be used:

awk -F, '{print $3}' file

First I tried this code

const peopleSchema = new mongoose.Schema({
  name: String,
  friends: [
    {
      firstName: String,
      lastName: String,
    },
  ],
});
const People = mongoose.model("person", peopleSchema);
const first = new Note({
  name: "Yash Salvi",
  notes: [
    {
      firstName: "Johnny",
      lastName: "Johnson",
    },
  ],
});
first.save();
const friendNew = {
  firstName: "Alice",
  lastName: "Parker",
};
People.findOneAndUpdate(
  { name: "Yash Salvi" },
  { $push: { friends: friendNew } },
  function (error, success) {
    if (error) {
      console.log(error);
    } else {
      console.log(success);
    }
  }
);

But I noticed that only first friend (i.e. Johhny Johnson) gets saved and the objective to push array element in existing array of "friends" doesn't seem to work as when I run the code , in database in only shows "First friend" and "friends" array has only one element ! So the simple solution is written below

const peopleSchema = new mongoose.Schema({
  name: String,
  friends: [
    {
      firstName: String,
      lastName: String,
    },
  ],
});
const People = mongoose.model("person", peopleSchema);
const first = new Note({
  name: "Yash Salvi",
  notes: [
    {
      firstName: "Johnny",
      lastName: "Johnson",
    },
  ],
});
first.save();
const friendNew = {
  firstName: "Alice",
  lastName: "Parker",
};
People.findOneAndUpdate(
  { name: "Yash Salvi" },
  { $push: { friends: friendNew } },
  { upsert: true }
);

Adding "{ upsert: true }" solved problem in my case and once code is saved and I run it , I see that "friends" array now has 2 elements ! The upsert = true option creates the object if it doesn't exist. default is set to false.

if it doesn't work use below snippet

People.findOneAndUpdate(
  { name: "Yash Salvi" },
  { $push: { friends: friendNew } },
).exec();

set style="height:300px !important;" and "imgBanner" for img tag.

<img src="/image/1.jpg" class="imgBanner" style="width:100%; height:300px !important;">

then if you want responsive image, so you can use jquery as:

$.(function(){
   $(window).resize(respWhenResize);
   respWhenResize();
 })



respWhenResize(){
 
       if (pagesize < 578) {
         $('.imgBanner').css('height','200px')
        } else if (pagesize > 578 ) {
            $('.imgBanner').css('height','300px')
        }
     }

<html>
<head>
<script>
    function putText() {
        var simpleText = "hello_world";
        var finalSplitText = simpleText.split("_");
        var splitText = finalSplitText[0];
        document.getElementById("destination").innerHTML = "I need the value of " + splitText + " variable here";
    }
</script>
</head>
<body onLoad = putText()>
    <a id="destination" href = test.html>I need the value of "splitText" variable here</a>
</body>
</html>

I think the best way is to use currentTarget property instead of target property.

The currentTarget read-only property of the Event interface identifies the current target for the event, as the event traverses the DOM. It always refers to the element to which the event handler has been attached, as opposed to Event.target, which identifies the element on which the event occurred.

For example:

<a href="#"><span class="icon"></span> blah blah</a>

Javascript:

a.addEventListener('click', e => {
    e.currentTarget; // always returns "a" element
    e.target; // may return "a" or "span"
})

date.setTime(milliseconds);

this is for set milliseconds in date

long milli = date.getTime();

This is for get time in milliseconds.

Returns the number of milliseconds since January 1, 1970, 00:00:00 GMT

Thread.Sleep(5000);

This did help me but InterruptedException exception needs to be taken care of. So better surround it with try and catch:

try {
    Thread.Sleep(5000);
} catch (InterruptedException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

OR

Add throws declaration:

public class myClass {
    public static void main(String[] args) throws InterruptedException
    { ... }

I would prefer the second one since one can then use sleep() as many times as it wants and avoid the repetition of try and catch block every time wherever sleep() has been used.

If you don't want to use an extra parent view to set the background, you can subclass UILabel and override textRectForBounds:limitedToNumberOfLines:. I'd add a textEdgeInsets property or similar and then do

- (CGRect)textRectForBounds:(CGRect)bounds limitedToNumberOfLines:(NSInteger)numberOfLines
{
  return [super textRectForBounds:UIEdgeInsetsInsetRect(bounds,textEdgeInsets) limitedToNumberOfLines:numberOfLines];
}

For robustness, you might also want to call [self setNeedsDisplay] in setTextEdgeInsets:, but I usually don't bother.

CSS:

table { 
    table-layout:fixed;
}

Update with CSS from the comments:

td { 
    overflow: hidden; 
    text-overflow: ellipsis; 
    word-wrap: break-word;
}

For mobile phones I leave the table width but assign an additional CSS class to the table to enable horizontal scrolling (table will not go over the mobile screen anymore):

@media only screen and (max-width: 480px) {
    /* horizontal scrollbar for tables if mobile screen */
    .tablemobile {
        overflow-x: auto;
        display: block;
    }
}

Sufficient enough.

For checking an array empty() is better than sizeof().

If the array contains huge amount of data. It will takes more times for counting the size of the array. But checking empty is always easy.

//for empty
  if(!empty($array))
     echo 'Data exist';
  else 
     echo 'No data';


 //for sizeof
 if(sizeof($array)>1)
      echo 'Data exist';
 else 
    echo 'No data';

Or you can exploit the fact that Collections.sort() (or Arrays.sort()) is stable (it doesn't reorder elements that are equal) and use a Comparator to sort by age first and then another one to sort by name.

In this specific case this isn't a very good idea but if you have to be able to change the sort order in runtime, it might be useful.

In my case, I had to do the following while running with Junit5

@SpringBootTest(classes = {abc.class}) @ExtendWith(SpringExtension.class

Here abc.class was the class that was being tested

The new ASP.NET Web API is a continuation of the previous WCF Web API project (although some of the concepts have changed).

WCF was originally created to enable SOAP-based services. For simpler RESTful or RPCish services (think clients like jQuery) ASP.NET Web API should be good choice.

For us, WCF is used for SOAP and Web API for REST. I wish Web API supported SOAP too. We are not using advanced features of WCF. Here is comparison from MSDN:

ASP.net Web API is all about HTTP and REST based GET,POST,PUT,DELETE with well know ASP.net MVC style of programming and JSON returnable; web API is for all the light weight process and pure HTTP based components. For one to go ahead with WCF even for simple or simplest single web service it will bring all the extra baggage. For light weight simple service for ajax or dynamic calls always WebApi just solves the need. This neatly complements or helps in parallel to the ASP.net MVC.

Check out the podcast : Hanselminutes Podcast 264 - This is not your father's WCF - All about the WebAPI with Glenn Block by Scott Hanselman for more information.

In the scenarios listed below you should go for WCF:

1. If you need to send data on protocols like TCP, MSMQ or MIME
2. If the consuming client just knows how to consume SOAP messages

WEB API is a framework for developing RESTful/HTTP services.

There are so many clients that do not understand SOAP like Browsers, HTML5, in those cases WEB APIs are a good choice.

HTTP services header specifies how to secure service, how to cache the information, type of the message body and HTTP body can specify any type of content like HTML not just XML as SOAP services.

Try this

div:nth-child(4n+4)

I had this recently after refactoring in a new connection manager. A new routine accepted a transaction so it could be run as part of a batch, problem was with a using block:

public IEnumerable<T> Query<T>(IDbTransaction transaction, string command, dynamic param = null)
{
  using (transaction.Connection)
  {
    using (transaction)
    {
      return transaction.Connection.Query<T>(command, new DynamicParameters(param), transaction, commandType: CommandType.StoredProcedure);
    }
  }
}

It looks as though the outer using was closing the underlying connection thus any attempts to commit or rollback the transaction threw up the message "This SqlTransaction has completed; it is no longer usable."

I removed the usings added a covering test and the problem went away.

public IEnumerable<T> Query<T>(IDbTransaction transaction, string command, dynamic param = null)
{
  return transaction.Connection.Query<T>(command, new DynamicParameters(param), transaction, commandType: CommandType.StoredProcedure);
}

Check for anything that might be closing the connection while inside the context of a transaction.

You need to find reference of existing Fragment and remove that fragment using below code. You need add/commit fragment using one tag ex. "TAG_FRAGMENT".

Fragment fragment = getSupportFragmentManager().findFragmentByTag(TAG_FRAGMENT);
if(fragment != null)
    getSupportFragmentManager().beginTransaction().remove(fragment).commit();

That is it.

As others said, they produce identical output on printf, but behave differently on scanf. I would prefer %d over %i for this reason. A number that is printed with %d can be read in with %d and you will get the same number. That is not always true with %i, if you ever choose to use zero padding. Because it is common to copy printf format strings into scanf format strings, I would avoid %i, since it could give you a surprising bug introduction:

I write fprintf("%i ...", ...);

You copy and write fscanf(%i ...", ...);

I decide I want to align columns more nicely and make alphabetization behave the same as sorting: fprintf("%03i ...", ...); (or %04d)

Now when you read my numbers, anything between 10 and 99 is interpreted in octal. Oops.

If you want decimal formatting, just say so.

How is the HashMap declaration expressed in that scope? It should be:

HashMap<String, ArrayList> dictMap

If not, it is assumed to be Objects.

For instance, if your code is:

HashMap dictMap = new HashMap<String, ArrayList>();
...
ArrayList current = dictMap.get(dictCode);

that will not work. Instead you want:

HashMap<String, ArrayList> dictMap = new HashMap<String, Arraylist>();
...
ArrayList current = dictMap.get(dictCode);

The way generics work is that the type information is available to the compiler, but is not available at runtime. This is called type erasure. The implementation of HashMap (or any other generics implementation) is dealing with Object. The type information is there for type safety checks during compile time. See the Generics documentation.

Also note that ArrayList is also implemented as a generic class, and thus you might want to specify a type there as well. Assuming your ArrayList contains your class MyClass, the line above might be:

HashMap<String, ArrayList<MyClass>> dictMap

try this

Object.keys(data).length

If IE < 9, you can loop through the object yourself with a for loop

var len = 0;
var i;

for (i in data) {
    if (data.hasOwnProperty(i)) {
        len++;
    }
}

when you pushing code to another branch just follow the below git command. Remember demo is my other branch name you can replace with your branch name.

git push origin master:demo

Looks like all the useEffect examples dont factor in you might want to trigger this with a state change.

const [aStateVariable, setAStateVariable] = useState(false);

const handleClick = () => {
   setAStateVariable(true);
}

useEffect(() => {
  if(aStateVariable === true) {
    window.scrollTo(0, 0)
  }
}, [aStateVariable])

If you want to replace multiple values in a data frame, looping through all columns might help.

Say you want to replace "" and 100:

na_codes <- c(100, "")
for (i in seq_along(df)) {
    df[[i]][df[[i]] %in% na_codes] <- NA
}

try out this it is much simpler ,this will help u:

// Open your local db as the input stream
    InputStream myInput = _context.getAssets().open(YOUR FILE NAME);

    // Path to the just created empty db
    String outFileName =SDCARD PATH + YOUR FILE NAME;

    // Open the empty db as the output stream
    OutputStream myOutput = new FileOutputStream(outFileName);

    // transfer bytes from the inputfile to the outputfile
    byte[] buffer = new byte[1024];
    int length;
    while ((length = myInput.read(buffer)) > 0) {
        myOutput.write(buffer, 0, length);
    }
    // Close the streams
    myOutput.flush();
    myOutput.close();
    myInput.close();

This one shows SQL that is currently "ACTIVE":-

select S.USERNAME, s.sid, s.osuser, t.sql_id, sql_text
from v$sqltext_with_newlines t,V$SESSION s
where t.address =s.sql_address
and t.hash_value = s.sql_hash_value
and s.status = 'ACTIVE'
and s.username <> 'SYSTEM'
order by s.sid,t.piece
/

This shows locks. Sometimes things are going slow, but it's because it is blocked waiting for a lock:

select
  object_name, 
  object_type, 
  session_id, 
  type,         -- Type or system/user lock
  lmode,        -- lock mode in which session holds lock
  request, 
  block, 
  ctime         -- Time since current mode was granted
from
  v$locked_object, all_objects, v$lock
where
  v$locked_object.object_id = all_objects.object_id AND
  v$lock.id1 = all_objects.object_id AND
  v$lock.sid = v$locked_object.session_id
order by
  session_id, ctime desc, object_name
/

This is a good one for finding long operations (e.g. full table scans). If it is because of lots of short operations, nothing will show up.

COLUMN percent FORMAT 999.99 

SELECT sid, to_char(start_time,'hh24:mi:ss') stime, 
message,( sofar/totalwork)* 100 percent 
FROM v$session_longops
WHERE sofar/totalwork < 1
/

The class declaration should be in the header file (Or in the source file if not shared).
File: foo.h

class foo
{
    private:
        static int i;
};

But the initialization should be in source file.
File: foo.cpp

int foo::i = 0;

If the initialization is in the header file then each file that includes the header file will have a definition of the static member. Thus during the link phase you will get linker errors as the code to initialize the variable will be defined in multiple source files. The initialisation of the static int i must be done outside of any function.

Note: Matt Curtis: points out that C++ allows the simplification of the above if the static member variable is of const int type (e.g. int, bool, char). You can then declare and initialize the member variable directly inside the class declaration in the header file:

class foo
{
    private:
        static int const i = 42;
};

In case you get the error "No 'Access-Control-Allow-Origin' header is present on the requested resource." Specifically for PUT and DELETE requests, you could try to disable WebDAV on IIS.

Apparently, the WebDAVModule is enabled by default and is disabling PUT and DELETE requests by default.

To disable the WebDAVModule, add this to your web.config:

<system.webServer>
  <modules runAllManagedModulesForAllRequests="false">
    <remove name="WebDAVModule" />
  </modules>
</system.webServer>

I like both @Qiao first answer and @Or's addition. For a sake of a little less processing I would like to add to Or's answer.

In @Or's answer keeping track of visited node is great. We can also allow the program to exit sooner that it currently is. At some point in the for loop the current_neighbour will have to be the end, and once that happens the shortest path is found and program can return.

I would modify the the method as follow, pay close attention to the for loop

graph = {
1: [2, 3, 4],
2: [5, 6],
3: [10],
4: [7, 8],
5: [9, 10],
7: [11, 12],
11: [13]
}


    def bfs(graph_to_search, start, end):
        queue = [[start]]
        visited = set()

    while queue:
        # Gets the first path in the queue
        path = queue.pop(0)

        # Gets the last node in the path
        vertex = path[-1]

        # Checks if we got to the end
        if vertex == end:
            return path
        # We check if the current node is already in the visited nodes set in order not to recheck it
        elif vertex not in visited:
            # enumerate all adjacent nodes, construct a new path and push it into the queue
            for current_neighbour in graph_to_search.get(vertex, []):
                new_path = list(path)
                new_path.append(current_neighbour)
                queue.append(new_path)

                #No need to visit other neighbour. Return at once
                if current_neighbour == end
                    return new_path;

            # Mark the vertex as visited
            visited.add(vertex)


print bfs(graph, 1, 13)

The output and everything else will be the same. However, the code will take less time to process. This is especially useful on larger graphs. I hope this helps someone in the future.

There is a bug in robocopy in interpreting the source name. If you include a back slash at the end of the path to describe a folder it keeps including the string for the source into the rest of the line. ie

robocopy "C:\back up\" %destination% /e Nothing here will go to the destination string

robocopy "C:\back up" %destination% /e but this works

I may be wrong but I think both should work!

Not a full answer Ok so this is just to supplement the information about parseInt, which is still very valid. Express doesn't allow the req or res objects to be modified at all (immutable). So if you want to modify/use this data effectively, you must copy it to another variable (var year = req.params.year).

This is my solution to the problem. I have two classes implementing Runnable, one prints odd sequence and the other prints even. I have an instance of Object, that I use for lock. I initialize the two classes with the same object. There is a synchronized block inside the run method of the two classes, where, inside a loop, each method prints one of the numbers, notifies the other thread, waiting for lock on the same object and then itself waits for the same lock again.

The classes :

public class PrintEven implements Runnable{
private Object lock;
public PrintEven(Object lock) {
    this.lock =  lock;
}
@Override
public void run() {
    synchronized (lock) {
        for (int i = 2; i <= 10; i+=2) {
            System.out.println("EVEN:="+i);
            lock.notify();
            try {
                //if(i!=10) lock.wait();
                lock.wait(500);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    }

  }
}


public class PrintOdd implements Runnable {
private Object lock;
public PrintOdd(Object lock) {
    this.lock =  lock;
}
@Override
public void run() {
    synchronized (lock) {
        for (int i = 1; i <= 10; i+=2) {
            System.out.println("ODD:="+i);
            lock.notify();
            try {
                //if(i!=9) lock.wait();
                lock.wait(500);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    }
}
}

public class PrintEvenOdd {
public static void main(String[] args){
    Object lock = new Object(); 
    Thread thread1 =  new Thread(new PrintOdd(lock));
    Thread thread2 =  new Thread(new PrintEven(lock));
    thread1.start();
    thread2.start();
}
}

The upper limit in my example is 10. Once the odd thread prints 9 or the even thread prints 10, then we don't need any of the threads to wait any more. So, we can handle that using one if-block. Or, we can use the overloaded wait(long timeout) method for the wait to be timed out. One flaw here though. With this code, we cannot guarantee which thread will start execution first.

Another example, using Lock and Condition

import java.util.concurrent.locks.Condition;
import java.util.concurrent.locks.Lock;
import java.util.concurrent.locks.ReentrantLock;

public class LockConditionOddEven {
 public static void main(String[] args) {
    Lock lock =  new ReentrantLock();
    Condition evenCondition = lock.newCondition();
    Condition oddCondition = lock.newCondition();
    Thread evenThread =  new Thread(new EvenPrinter(10, lock, evenCondition, oddCondition));
    Thread oddThread =  new Thread(new OddPrinter(10, lock, evenCondition, oddCondition));
    oddThread.start();
    evenThread.start();
}

static class OddPrinter implements Runnable{
    int i = 1;
    int limit;
    Lock lock;
    Condition evenCondition;
    Condition oddCondition;

    public OddPrinter(int limit) {
        super();
        this.limit = limit;
    }

    public OddPrinter(int limit, Lock lock, Condition evenCondition, Condition oddCondition) {
        super();
        this.limit = limit;
        this.lock = lock;
        this.evenCondition = evenCondition;
        this.oddCondition = oddCondition;
    }

    @Override
    public void run() {
        while( i <=limit) {
            lock.lock();
            System.out.println("Odd:"+i);
            evenCondition.signal();
            i+=2;
            try {
                oddCondition.await();
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }finally {
                lock.unlock();
            }
        }
    }
}

static class EvenPrinter implements Runnable{
    int i = 2;
    int limit;
    Lock lock;
    Condition evenCondition;
    Condition oddCondition;

    public EvenPrinter(int limit) {
        super();
        this.limit = limit;
    }


    public EvenPrinter(int limit, Lock lock, Condition evenCondition, Condition oddCondition) {
        super();
        this.limit = limit;
        this.lock = lock;
        this.evenCondition = evenCondition;
        this.oddCondition = oddCondition;
    }


    @Override
    public void run() {
        while( i <=limit) {
            lock.lock();
            System.out.println("Even:"+i);
            i+=2;
            oddCondition.signal();
            try {
                evenCondition.await();
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }finally {
                lock.unlock();
            }
        }
    }
}

}

A simple solution to this problem is to return from the render loop if the frame is not required to render:

const FPS = 60;
let prevTick = 0;    

function render() 
{
    requestAnimationFrame(render);

    // clamp to fixed framerate
    let now = Math.round(FPS * Date.now() / 1000);
    if (now == prevTick) return;
    prevTick = now;

    // otherwise, do your stuff ...
}

It's important to know that requestAnimationFrame depends on the users monitor refresh rate (vsync). So, relying on requestAnimationFrame for game speed for example will make it unplayable on 200Hz monitors if you're not using a separate timer mechanism in your simulation.

You need the following functions to do this in PHP:

strpos Find the position of the first occurrence of a substring in a string

strrpos Find the position of the last occurrence of a substring in a string

substr Return part of a string

Here's the signature of the substr function:

string substr ( string $string , int $start [, int $length ] )

The signature of the substring function (Java) looks a bit different:

string substring( int beginIndex, int endIndex )

substring (Java) expects the end-index as the last parameter, but substr (PHP) expects a length.

It's not hard, to get the desired length by the end-index in PHP:

$sub = substr($str, $start, $end - $start);

Here is the working code

$start = strpos($message, '-') + 1;
if ($req_type === 'RMT') {
    $pt_password = substr($message, $start);
}
else {
    $end = strrpos($message, '-');
    $pt_password = substr($message, $start, $end - $start);
}

Normally you should use margin: 0 auto on the div as mentioned in the other answers, but you'll have to specify a width for the div. If you don't want to specify a width you could either (this is depending on what you're trying to do) use margins, something like margin: 0 200px; , this should make your content seems as if it's centered, you could also see the answer of Leyu to my question

SELECT tab.*,
    row_number() OVER () as rnum
  FROM tab;

Here's the relevant section in the docs.

P.S. This, in fact, fully matches the answer in the referenced question.

I’m going to hold the unpopular on SO selenium tag opinion that XPath is preferable to CSS in the longer run.

This long post has two sections - first I'll put a back-of-the-napkin proof the performance difference between the two is 0.1-0.3 milliseconds (yes; that's 100 microseconds), and then I'll share my opinion why XPath is more powerful.

Performance difference

Let's first tackle "the elephant in the room" – that xpath is slower than css.

With the current cpu power (read: anything x86 produced since 2013), even on browserstack/saucelabs/aws VMs, and the development of the browsers (read: all the popular ones in the last 5 years) that is hardly the case. The browser's engines have developed, the support of xpath is uniform, IE is out of the picture (hopefully for most of us). This comparison in the other answer is being cited all over the place, but it is very contextual – how many are running – or care about – automation against IE8?

If there is a difference, it is in a fraction of a millisecond.

Yet, most higher-level frameworks add at least 1ms of overhead over the raw selenium call anyways (wrappers, handlers, state storing etc); my personal weapon of choice – RobotFramework – adds at least 2ms, which I am more than happy to sacrifice for what it provides. A network roundtrip from an AWS us-east-1 to BrowserStack's hub is usually 11 milliseconds.

So with remote browsers if there is a difference between xpath and css, it is overshadowed by everything else, in orders of magnitude.

The measurements

There are not that many public comparisons (I've really seen only the cited one), so – here's a rough single-case, dummy and simple one.
It will locate an element by the two strategies X times, and compare the average time for that.

The target – BrowserStack's landing page, and its "Sign Up" button; a screenshot of the html as writing this post:

Here's the test code (python):

from selenium import webdriver
import timeit


if __name__ == '__main__':

    xpath_locator = '//div[@class="button-section col-xs-12 row"]'
    css_locator = 'div.button-section.col-xs-12.row'

    repetitions = 1000

    driver = webdriver.Chrome()
    driver.get('https://www.browserstack.com/')

    css_time = timeit.timeit("driver.find_element_by_css_selector(css_locator)", 
                             number=repetitions, globals=globals())
    xpath_time = timeit.timeit('driver.find_element_by_xpath(xpath_locator)', 
                             number=repetitions, globals=globals())

    driver.quit()

    print("css total time {} repeats: {:.2f}s, per find: {:.2f}ms".
          format(repetitions, css_time, (css_time/repetitions)*1000))
    print("xpath total time for {} repeats: {:.2f}s, per find: {:.2f}ms".
          format(repetitions, xpath_time, (xpath_time/repetitions)*1000))

For those not familiar with Python – it opens the page, and finds the element – first with the css locator, then with the xpath; the find operation is repeated 1,000 times. The output is the total time in seconds for the 1,000 repetitions, and average time for one find in milliseconds.

The locators are:

• for xpath – "a div element having this exact class value, somewhere in the DOM";
• the css is similar – "a div element with this class, somewhere in the DOM".

Deliberately chosen not to be over-tuned; also, the class selector is cited for the css as "the second fastest after an id".

The environment – Chrome v66.0.3359.139, chromedriver v2.38, cpu: ULV Core M-5Y10 usually running at 1.5GHz (yes, a "word-processing" one, not even a regular i7 beast).

Here's the output:

css total time 1000 repeats: 8.84s, per find: 8.84ms

xpath total time for 1000 repeats: 8.52s, per find: 8.52ms

Obviously the per find timings are pretty close; the difference is 0.32 milliseconds. Don't jump "the xpath is faster" – sometimes it is, sometimes it's css.

Let's try with another set of locators, a tiny-bit more complicated – an attribute having a substring (common approach at least for me, going after an element's class when a part of it bears functional meaning):

xpath_locator = '//div[contains(@class, "button-section")]'
css_locator = 'div[class~=button-section]'

The two locators are again semantically the same – "find a div element having in its class attribute this substring".
Here are the results:

css total time 1000 repeats: 8.60s, per find: 8.60ms

xpath total time for 1000 repeats: 8.75s, per find: 8.75ms

Diff of 0.15ms.

As an exercise - the same test as done in the linked blog in the comments/other answer - the test page is public, and so is the testing code.

They are doing a couple of things in the code - clicking on a column to sort by it, then getting the values, and checking the UI sort is correct.
I'll cut it - just get the locators, after all - this is the root test, right?

The same code as above, with these changes in:

• The url is now http://the-internet.herokuapp.com/tables; there are 2 tests.

• The locators for the first one - "Finding Elements By ID and Class" - are:

css_locator = '#table2 tbody .dues'
xpath_locator = "//table[@id='table2']//tr/td[contains(@class,'dues')]"

And here is the outcome:

css total time 1000 repeats: 8.24s, per find: 8.24ms

xpath total time for 1000 repeats: 8.45s, per find: 8.45ms

Diff of 0.2 milliseconds.

The "Finding Elements By Traversing":

css_locator = '#table1 tbody tr td:nth-of-type(4)'
xpath_locator = "//table[@id='table1']//tr/td[4]"

The result:

css total time 1000 repeats: 9.29s, per find: 9.29ms

xpath total time for 1000 repeats: 8.79s, per find: 8.79ms

This time it is 0.5 ms (in reverse, xpath turned out "faster" here).

So 5 years later (better browsers engines) and focusing only on the locators performance (no actions like sorting in the UI, etc), the same testbed - there is practically no difference between CSS and XPath.

So, out of xpath and css, which of the two to choose for performance? The answer is simple – choose locating by id.

Long story short, if the id of an element is unique (as it's supposed to be according to the specs), its value plays an important role in the browser's internal representation of the DOM, and thus is usually the fastest.

Yet, unique and constant (e.g. not auto-generated) ids are not always available, which brings us to "why XPath if there's CSS?"

The XPath advantage

With the performance out of the picture, why do I think xpath is better? Simple – versatility, and power.

Xpath is a language developed for working with XML documents; as such, it allows for much more powerful constructs than css.
For example, navigation in every direction in the tree – find an element, then go to its grandparent and search for a child of it having certain properties.
It allows embedded boolean conditions – cond1 and not(cond2 or not(cond3 and cond4)); embedded selectors – "find a div having these children with these attributes, and then navigate according to it".
XPath allows searching based on a node's value (its text) – however frowned upon this practice is, it does come in handy especially in badly structured documents (no definite attributes to step on, like dynamic ids and classes - locate the element by its text content).

The stepping in css is definitely easier – one can start writing selectors in a matter of minutes; but after a couple of days of usage, the power and possibilities xpath has quickly overcomes css.
And purely subjective – a complex css is much harder to read than a complex xpath expression.

Outro ;)

Finally, again very subjective - which one to chose?

IMO, there is no right or wrong choice - they are different solutions to the same problem, and whatever is more suitable for the job should be picked.

Being "a fan" of XPath I'm not shy to use in my projects a mix of both - heck, sometimes it is much faster to just throw a CSS one, if I know it will do the work just fine.

While commonly referred to as a 'sign bit', the binary values we usually use do not have a true sign bit.

Most computers use two's-complement arithmetic. Negative numbers are created by taking the one's-complement (flip all the bits) and adding one:

      5 (decimal) -> 00000101 (binary)
      1's complement: 11111010
      add 1: 11111011 which is 'FB' in hex


This is why a signed byte holds values from -128 to +127 instead of -127 to +127:

      1 0 0 0 0 0 0 0 = -128
      1 0 0 0 0 0 0 1 = -127
          - - -
      1 1 1 1 1 1 1 0 = -2
      1 1 1 1 1 1 1 1 = -1
      0 0 0 0 0 0 0 0 = 0
      0 0 0 0 0 0 0 1 = 1
      0 0 0 0 0 0 1 0 = 2
          - - -
      0 1 1 1 1 1 1 0 = 126
      0 1 1 1 1 1 1 1 = 127
      (add 1 to 127 gives:)
      1 0 0 0 0 0 0 0   which we see at the top of this chart is -128.


If we had a proper sign bit, the value range would be the same (e.g., -127 to +127) because one bit is reserved for the sign. If the most-significant-bit is the sign bit, we'd have:

      5 (decimal) -> 00000101 (binary)
      -5 (decimal) -> 10000101 (binary)

The interesting thing in this case is we have both a zero and a negative zero:
      0 (decimal) -> 00000000 (binary)
      -0 (decimal) -> 10000000 (binary)


We don't have -0 with two's-complement; what would be -0 is -128 (or to be more general, one more than the largest positive value). We do with one's complement though; all 1 bits is negative 0.

Mathematically, -0 equals 0. I vaguely remember a computer where -0 < 0, but I can't find any reference to it now.

We already have tons of options to get mean by group, adding one more from mosaic package.

mosaic::mean(speed~dive, data = df)
#dive1 dive2 
#0.579 0.440 

This returns a named numeric vector, if needed a dataframe we can wrap it in stack

stack(mosaic::mean(speed~dive, data = df))

#  values   ind
#1  0.579 dive1
#2  0.440 dive2

data

set.seed(123)
df <- data.frame(dive=factor(sample(c("dive1","dive2"),10,replace=TRUE)),
                 speed=runif(10))

On the topic of cleaning up remote branches

git branch -r | xargs -t -n 1 git branch -r --contains

This lists each remote branch followed by which remote branches their latest SHAs are within.

This is useful to discern which remote branches have been merged but not deleted, and which haven't been merged and thus are decaying.

If you're using 'tig' (its like gitk but terminal based) then you can

tig origin/feature/someones-decaying-feature

to see a branch's commit history without having to git checkout

For one thing, it says you already have that module installed. If you need to upgrade it, you should do something like this:

easy_install -U packageName

Of course, easy_install doesn't work very well if the package has some C headers that need to be compiled and you don't have the right version of Visual Studio installed. You might try using pip or distribute instead of easy_install and see if they work better.

Clearing my browser's cache fixed this issue for me. I had been switching between local development environments to do the django-blog-zinnia tutorial after working on another project when it happened. At first, I thought changing the order of INSTALLED_APPS to match the tutorial had caused it, but I set these back and was unable to correct it until clearing the cache.

Initially cursor is not on the first row show using moveToNext() you can iterate the cursor when record is not exist then it return false,unless it return true,

This is because you have not included web.xml in your web project and trying to build war using maven. To resolve this error, you need to set the failOnMissingWebXml to false in pom.xml file.

For example:

<properties>
    <failOnMissingWebXml>false</failOnMissingWebXml>   
</properties>

Please see the blog for more details: https://ankurjain26.blogspot.in/2017/05/error-assembling-war-webxml-attribute.html

Here is an ES6 implementation:

value = Array(...el.options).reduce((acc, option) => {
  if (option.selected === true) {
    acc.push(option.value);
  }
  return acc;
}, []);

With the Pendulum very complete library, we have the subtract method (and not "subStract"):

import pendulum
today = pendulum.datetime.today()  # 2020, january
lastmonth = today.subtract(months=1)
lastmonth.strftime('%Y%m')
# '201912'

We see that it handles jumping years.

The reverse equivalent is add.

This is the simplest way of printing the internal binary representation of an integer. For Example: If we take n as 17 then the output will be: 0000 0000 0000 0000 0000 0000 0001 0001

void bitPattern(int n) {

        int mask = 1 << 31;
        int count = 0;
        while(mask != 0) {
            if(count%4 == 0)
                System.out.print(" ");

            if((mask&n) == 0) 

                System.out.print("0");



            else 
                System.out.print("1");


            count++;
            mask = mask >>> 1;


    }
    System.out.println();
}

A slightly out-of-the-box method would be to script up a solution in AutoHotKey. I use this, and it's not perfect, but works and is free. Essentially, this script assigns a hotkey to CTRL+SHIFT+R which will copy the selected SQL in SSMS (CTRL+C), save off a datestamp SQL file, and then execute the highlighted query (F5). If you aren't used to AHK scripts, the leading semicolon is a comment.

;CTRL+SHIFT+R to run a query that is first saved off
^+r::
;Copy
Send, ^c
; Set variables
EnvGet, HomeDir, USERPROFILE
FormatTime, DateString,,yyyyMMdd
FormatTime, TimeString,,hhmmss
; Make a spot to save the clipboard
FileCreateDir %HomeDir%\Documents\sqlhist\%DateString%
FileAppend, %Clipboard%, %HomeDir%\Documents\sqlhist\%DateString%\%TimeString%.sql
; execute the query
Send, {f5}
Return

The biggest limitations are that this script won't work if you click "Execute" rather than use the keyboard shortcut, and this script won't save off the whole file - just the selected text. But, you could always modify the script to execute the query, and then select all (CTRL+A) before the copy/save.

Using a modern editor with "find in files" features will let you search your SQL history. You could even get fancy and scrape your files into a SQLite3 database to query your queries.

I needed a variation on this, which I expect will be useful to others:

function diffs() {
        diff "${@:3}" <(sort "$1") <(sort "$2")
}

The "${@:3}" part means all the members of the array starting at 3. So this function implements a sorted diff by passing the first two arguments to diff through sort and then passing all other arguments to diff, so you can call it similarly to diff:

diffs file1 file2 [other diff args, e.g. -y]

You're looking for calls to sys.exit() in the script. The argument to that method is returned to the environment as the exit code.

It's fairly likely that the script is never calling the exit method, and that 0 is the default exit code.

Here's my example in which I work

You could subscribe for the onkeypress event:

<input type="text" class="textfield" value="" id="extra7" name="extra7" onkeypress="return isNumber(event)" />

and then define the isNumber function:

function isNumber(evt) {
    evt = (evt) ? evt : window.event;
    var charCode = (evt.which) ? evt.which : evt.keyCode;
    if (charCode > 31 && (charCode < 48 || charCode > 57)) {
        return false;
    }
    return true;
}

You can see it in action here.

^[^<>]+$

The caret in the character class ([^) means match anything but, so this means, beginning of string, then one or more of anything except < and >, then the end of the string.

You're interested in the collation. You could build something based on this snippet:

SELECT DATABASEPROPERTYEX('master', 'Collation');

Update
Based on your edit — If @test and @TEST can ever refer to two different variables, it's not SQL Server. If you see problems where the same variable is not equal to itself, check if that variable is NULL, because NULL = NULL returns `false.

For users of modern DataTables (1.10 and above), all the answers and examples on this page are for the old api, not the new. I had a very hard time finding a newer example but finally did find this DT forum post (TL;DR for most folks) which led me to this concise example.

The example code worked for me after I finally noticed the $() selector syntax immediately surrounding the html string. You have to add a node not a string.

That example really is worth looking at but, in the spirit of SO, if you just want to see a snippet of code that works:

var table = $('#example').DataTable();
  table.rows.add( $(
          '<tr>'+
          '  <td>Tiger Nixon</td>'+
          '  <td>System Architect</td>'+
          '  <td>Edinburgh</td>'+
          '  <td>61</td>'+
          '  <td>2011/04/25</td>'+
          '  <td>$3,120</td>'+
          '</tr>'
  ) ).draw();

The careful reader might note that, since we are adding only one row of data, that table.row.add(...) should work as well and did for me.

from two tables with foreign key you can try this Query:

DELETE T1, T2
FROM T1
INNER JOIN T2 ON T1.key = T2.key
WHERE condition

After some experimentation (see below), I can confirm that as of September 2017, nothing has changed with regards to the functionality described in the accepted answer:-

1. Rextester demo for Oracle 11g: Empty strings are inserted as NULLs for both VARCHAR and VARCHAR2.
2. LiveSQL demo for Oracle 12c: Same results.

The historical reason for these two keywords is explained well in an answer to a different question.

BE CAREFUL

In some browsers:

flex:1; does not equal flex:1 1 0;

flex:1; = flex:1 1 0n; (where n is a length unit).

• flex-grow: A number specifying how much the item will grow relative to the rest of the flexible items.
• flex-shrink A number specifying how much the item will shrink relative to the rest of the flexible items
• flex-basis The length of the item. Legal values: "auto", "inherit", or a number followed by "%", "px", "em" or any other length unit.

The key point here is that flex-basis requires a length unit.

In Chrome for example flex:1 and flex:1 1 0 produce different results. In most circumstances it may appear that flex:1 1 0; is working but let's examine what really happens:

EXAMPLE

Flex basis is ignored and only flex-grow and flex-shrink are applied.

flex:1 1 0; = flex:1 1; = flex:1;

This may at first glance appear ok however if the applied unit of the container is nested; expect the unexpected!

Try this example in CHROME

.Wrap{_x000D_
  padding:10px;_x000D_
  background: #333;_x000D_
}_x000D_
.Flex110x, .Flex1, .Flex110, .Wrap {_x000D_

.Flex110 {_x000D_
  -webkit-flex: 1 1 0;_x000D_
  flex: 1 1 0;_x000D_

.Flex110x{_x000D_
  -webkit-flex: 1 1 0%;_x000D_
  flex: 1 1 0%;_x000D_
}

FLEX 1 1 0_x000D_
<div class="Wrap">_x000D_

<div class="Wrap">_x000D_
  <div class="Flex110x">_x000D_
    <input type="submit" name="test3" value="TEST 3">_x000D_
  </div>_x000D_
</div>

COMPATIBILITY

It should be noted that this fails because some browsers have failed to adhere to the specification.

Browsers that use the full flex specification:

• Firefox - ?
• Edge - ? (I know, I was shocked too.)
• Chrome - x
• Brave - x
• Opera - x
• IE - (lol, it works without length unit but not with one.)

UPDATE 2019

Latest versions of Chrome seem to have finally rectified this issue but other browsers still have not.

Tested and working in Chrome Ver 74.

For me the problem was that I was using obsolete versions of the cordova android and ios platforms. So upgrading to [email protected] and [email protected] solved it.

You can upgrade to these specific versions:

cordova platforms rm android
cordova platforms add [email protected]
cordova platforms rm ios
cordova platforms add [email protected]

try this, it will not work for the first selection, then it will work nice :)

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
    On Error GoTo 10
    If Target.Count > 1 Then GoTo 10
    Target.Value = lastcel(Target.Value)

End Sub


Function lastcel(lC_vAl As String) As String

    lastcel = vlu
    vlu = lC_vAl
End Function

Simply define a function and set the value of your Combobox to empty/null or whatever you want. Try the following.

def Reset():
    cmb.set("")

here, cmb is a variable in which you have assigned the Combobox. Now call that function in a button such as,

btn2 = ttk.Button(root, text="Reset",command=Reset)

The toggle tells Bootstrap what to do and the target tells Bootstrap which element is going to open. So whenever a link like that is clicked, a modal with an id of “basicModal” will appear.

Run these codes in thread or AsyncTask. In order to avoid duplicated callings of same _url(one time for getContentLength(), one time of openStream()), use IOUtils.toByteArray of Apache.

void downloadFile(String _url, String _name) {
    try {
        URL u = new URL(_url);
        DataInputStream stream = new DataInputStream(u.openStream());
        byte[] buffer = IOUtils.toByteArray(stream);
        FileOutputStream fos = mContext.openFileOutput(_name, Context.MODE_PRIVATE);
        fos.write(buffer);
        fos.flush();
        fos.close();
    } catch (FileNotFoundException e) {
        e.printStackTrace();
        return;
    } catch (IOException e) {
        e.printStackTrace();
        return;
    }
}

You can use std::ifstream, funcion like is_open, fail, for example as below code (the cout "open" means file exist or not):

I tend to use du in a simple way.

du -sh */ | sort -n

This provides me with an idea of what directories are consuming the most space. I can then run more precise searches later.

About Abstract Classes

• Cannot create object of an abstract class
• Can create variables (can behave like datatypes)
• If a child can not override at least of one abstract method of the parent, then child also becomes abstract
• Abstract classes are useless without child classes

The purpose of an abstract class is to behave like a base. In inheritance hierarchy you will see abstract classes towards the top.

If you have a collection of objects that you load using stored procedure you can also use LoadFromCollection.

using (ExcelPackage package = new ExcelPackage(file))
{
    ExcelWorksheet worksheet = package.Workbook.Worksheets.Add("test");

    worksheet.Cells["A1"].LoadFromCollection(myColl, true, OfficeOpenXml.Table.TableStyles.Medium1);

    package.Save();
}

Simply this, no extra div or JavaScript needed, just pure CSS (jsfiddle demo):

HTML

<a href="javascript:alert('Hello!')" class="changesImgOnHover">
    <img src="http://dummyimage.com/50x25/00f/ff0.png&text=Hello!" alt="Hello!">
</a>

CSS

.changesImgOnHover {
    display: inline-block; /* or just block */
    width: 50px;
    background: url('http://dummyimage.com/50x25/0f0/f00.png&text=Hello!') no-repeat;
}
.changesImgOnHover:hover img {
    visibility: hidden;
}

The concept of number/length/dimensionality doesn't really make sense for an Object, and needing it suggests you really want an Array to me.

Edit: Pointed out to me that you want an O(1) for this. To the best of my knowledge no such way exists I'm afraid.

INSERT INTO Test([col1],[col2]) (
    SELECT 
        a.Name AS [col1],
        b.sub AS [col2] 
    FROM IdTable b 
    INNER JOIN Nametable a ON b.no = a.no
)

In my case I just had to quit the simulator...

You should be able to transfer the Application to another Username. You would need all your old user information to transfer it. The application would remove it's self from old account to new account. Also you could put a limit on how many times you where allowed to transfer it. If you transfer it to the application could expire after a year and force to buy update.

capitalize the first letter of Only

input[readOnly] {_x000D_
      background: red !important;_x000D_
    }

<input type="text" name="country" value="China" readonly="readonly" />

This happens when saving an object when Hibernate thinks it needs to save an object that is associated with the one you are saving.

I had this problem and did not want to save changes to the referenced object so I wanted the cascade type to be NONE.

The trick is to ensure that the ID and VERSION in the referenced object is set so that Hibernate does not think that the referenced object is a new object that needs saving. This worked for me.

Look through all of the relationships in the class you are saving to work out the associated objects (and the associated objects of the associated objects) and ensure that the ID and VERSION is set in all objects of the object tree.

Your nav div is actually centered correctly. But the ul inside is not. Give the ul a specific width and center that as well.

Here is some code using java 6 to get you started:

JSONObject jo = new JSONObject();
jo.put("firstName", "John");
jo.put("lastName", "Doe");

JSONArray ja = new JSONArray();
ja.put(jo);

JSONObject mainObj = new JSONObject();
mainObj.put("employees", ja);

Edit: Since there has been a lot of confusion about put vs add here I will attempt to explain the difference. In java 6 org.json.JSONArray contains the put method and in java 7 javax.json contains the add method.

An example of this using the builder pattern in java 7 looks something like this:

JsonObject jo = Json.createObjectBuilder()
  .add("employees", Json.createArrayBuilder()
    .add(Json.createObjectBuilder()
      .add("firstName", "John")
      .add("lastName", "Doe")))
  .build();

document.getElementById('iframeID').contentWindow.location.href

You can't access cross-domain iframe location at all.

<object>.__class__.__name__

See this related thread. Basically, os.environ is found on import, and os.getenv is a wrapper to os.environ.get, at least in CPython.

EDIT: To respond to a comment, in CPython, os.getenv is basically a shortcut to os.environ.get ; since os.environ is loaded at import of os, and only then, the same holds for os.getenv.

The answer has been given by Faisal Khurshid and Michael_B already.
This is just an attempt to make a possible solution more obvious.

For IE11 and below you need to enable grid's older specification in the parent div e.g. body or like here "grid" like so:

.grid-parent{display:-ms-grid;}

then define the amount and width of the columns and rows like e.g. so:

.grid-parent{
  -ms-grid-columns: 1fr 3fr;
  -ms-grid-rows: 4fr;
}

finally you need to explicitly tell the browser where your element (item) should be placed in e.g. like so:

.grid-item-1{
  -ms-grid-column: 1;
  -ms-grid-row: 1;
}

.grid-item-2{
  -ms-grid-column: 2;
  -ms-grid-row: 1;
}

In MySQL, I use <> to preferentially place specific rows at the front of a sort request.

For instance, under the column topic, I have the classifications of 'Chair', 'Metabolomics', 'Proteomics', and 'Endocrine'. I always want to list any individual(s) with the topic 'Chair', first, and then list the other members in alphabetical order based on their topic and then their name_last.

I do this with:

SELECT scicom_list ORDER BY topic <> 'Chair',topic,name_last;

This outputs the rows in the order of:
Chair
Endocrine
Metabolomics
Proteomics

Notice that topic <> 'Chair' is used to select all the rows with 'Chair' first. It then sorts the rows where topic = Chair by name_last.*

*This is a bit counterintuitive since <> equals != based on other feedback in this post.

This syntax can also be used to prioritize multiple categories. For instance, if I want to have "Chair" and then "Vice Chair" listed before the rest of the topics, I use the following

SELECT scicom_list ORDER BY topic <> 'Chair',topic <> 'Vice Chair',topic,name_last;

This outputs the rows in the order of:
Chair
Vice Chair
Endocrine
Metabolomics
Proteomics

Try this one. It centers vertically and horizontally.

I wrote this function for myself (in Jupyter) and it was inspired by indraforyou's answer. It will plot all the layer outputs automatically. Your images must have a (x, y, 1) shape where 1 stands for 1 channel. You just call plot_layer_outputs(...) to plot.

%matplotlib inline
import matplotlib.pyplot as plt
from keras import backend as K

def get_layer_outputs():
    test_image = YOUR IMAGE GOES HERE!!!
    outputs    = [layer.output for layer in model.layers]          # all layer outputs
    comp_graph = [K.function([model.input]+ [K.learning_phase()], [output]) for output in outputs]  # evaluation functions

    # Testing
    layer_outputs_list = [op([test_image, 1.]) for op in comp_graph]
    layer_outputs = []

    for layer_output in layer_outputs_list:
        print(layer_output[0][0].shape, end='\n-------------------\n')
        layer_outputs.append(layer_output[0][0])

    return layer_outputs

def plot_layer_outputs(layer_number):    
    layer_outputs = get_layer_outputs()

    x_max = layer_outputs[layer_number].shape[0]
    y_max = layer_outputs[layer_number].shape[1]
    n     = layer_outputs[layer_number].shape[2]

    L = []
    for i in range(n):
        L.append(np.zeros((x_max, y_max)))

    for i in range(n):
        for x in range(x_max):
            for y in range(y_max):
                L[i][x][y] = layer_outputs[layer_number][x][y][i]


    for img in L:
        plt.figure()
        plt.imshow(img, interpolation='nearest')

As replace() creates/returns a new string rather than modifying the original (tt), you need to set the variable (tt) equal to the new string returned from the replace function.

tt = tt.replace(/,/g, '.')

If you used create-react-app to create your project then your public folder is accessible. So you need to add your image folder inside the public folder.

If id is sequential starting at 1, the simplest (and quickest) would be:

UPDATE `table` 
SET uid = ELT(id, 2952, 4925, 1592) 
WHERE id IN (1,2,3)

As ELT() returns the Nth element of the list of strings: str1 if N = 1, str2 if N = 2, and so on. Returns NULL if N is less than 1 or greater than the number of arguments.

Clearly, the above code only works if id is 1, 2, or 3. If id was 10, 20, or 30, either of the following would work:

UPDATE `table` 
SET uid = CASE id 
WHEN 10 THEN 2952 
WHEN 20 THEN 4925 
WHEN 30 THEN 1592 END CASE 
WHERE id IN (10, 20, 30)

or the simpler:

UPDATE `table` 
SET uid = ELT(FIELD(id, 10, 20, 30), 2952, 4925, 1592) 
WHERE id IN (10, 20, 30)

As FIELD() returns the index (position) of str in the str1, str2, str3, ... list. Returns 0 if str is not found.

There is already a library in Python called yahoo_finance so you'll need to download the library first using the following command line:

sudo pip install yahoo_finance

Then once you've installed the yahoo_finance library, here's a sample code that will download the data you need from Yahoo Finance:

#!/usr/bin/python
import yahoo_finance
import pandas as pd

symbol = yahoo_finance.Share("GOOG")
google_data = symbol.get_historical("1999-01-01", "2016-06-30")
google_df = pd.DataFrame(google_data)

# Output data into CSV
google_df.to_csv("/home/username/google_stock_data.csv")

This should do it. Let me know if it works.

UPDATE: The yahoo_finance library is no longer supported.

Open RUN then type %windir%\assembly\GAC_MSIL, this will open your dlls in folders' view you can then navigate to your dll named folder and open it, you will find your dll file and copy it easily

I was facing a similar difficulty and none of the solutions presented here were optimal for what I was working on. What I had was a series of functions to display content in a modal and I was trying to refactor it under a single object definition making the functions, methods of the class. The problem came in when I found one of the methods created some nav-buttons inside the modal themselves which used an onClick to one of the functions -- now an object of the class. I have considered (and am still considering) other methods to handle these nav buttons, but I was able to find the variable name for the class itself by sweeping the variables defined in the parent window. What I did was search for anything matching the 'instanceof' my class, and in case there might be more than one, I compared a specific property that was likely to be unique to each instance:

var myClass = function(varName)
{
    this.instanceName = ((varName != null) && (typeof(varName) == 'string') && (varName != '')) ? varName : null;

    /**
     * caching autosweep of window to try to find this instance's variable name
     **/
    this.getInstanceName = function() {
        if(this.instanceName == null)
        {
            for(z in window) {
                if((window[z] instanceof myClass) && (window[z].uniqueProperty === this.uniqueProperty)) {
                    this.instanceName = z;
                    break;
                }
            }
        }
        return this.instanceName;
    }
}

As of pip 10, the accepted answer will no longer work. The development team has removed access to the get_installed_distributions routine. There is an alternate function in the setuptools for doing the same thing. Here is an alternate version that works with pip 10:

import pkg_resources
installed_packages = pkg_resources.working_set
installed_packages_list = sorted(["%s==%s" % (i.key, i.version)
     for i in installed_packages])
print(installed_packages_list)

Please let me know if it will or won't work in previous versions of pip, too.

Just do:

echo substr($string, 0, -3);

You don't need to use a strlen call, since, as noted in the substr docs:

If length is given and is negative, then that many characters will be omitted from the end of string

Adding to the knowledge base, I got the same error for

if(class_iter->num == *int_iter)

Even though the IDE gave me the correct members for class_iter. Obviously, the problem is that "anything"::iterator doesn't have a member called num so I need to dereference it. Which doesn't work like this:

if(*class_iter->num == *int_iter)

...apparently. I eventually solved it with this:

if((*class_iter)->num == *int_iter)

I hope this helps someone who runs across this question the way I did.

IBOutlet

• It is a property.
• When the nib(IB) file is loaded, it becomes part of encapsulated data which connects to an instance variable.
• Each connection is unarchived and reestablished.

IBAction

• Attribute indicates that the method is an action that you can connect to from your storyboard in Interface Builder.

@ - Dynamic pattern IB - Interface Builder

Full control over file attributes is available in Java 7, as part of the "new" New IO facility (NIO.2). For example, POSIX permissions can be set on an existing file with setPosixFilePermissions(), or atomically at file creation with methods like createFile() or newByteChannel().

You can create a set of permissions using EnumSet.of(), but the helper method PosixFilePermissions.fromString() will uses a conventional format that will be more readable to many developers. For APIs that accept a FileAttribute, you can wrap the set of permissions with with PosixFilePermissions.asFileAttribute().

Set<PosixFilePermission> ownerWritable = PosixFilePermissions.fromString("rw-r--r--");
FileAttribute<?> permissions = PosixFilePermissions.asFileAttribute(ownerWritable);
Files.createFile(path, permissions);

In earlier versions of Java, using native code of your own, or exec-ing command-line utilities are common approaches.

This pen I found the other day seemed to do it beautifully, just a bit of css and 21 lines of javascript. I hadn't heard of the cloneNode js command until I found this, but it totally worked for what I needed for sure.

http://codepen.io/rikschennink/pen/zvcgx

Detail: A. Basically it looks at your content div and invokes a cloneNode on it so it creates a duplicate which it then places inside the overflow:hidden header object sitting on top of the page. B. Then it simply listens for scrolling so that both images seem to match and blurs the header image... annnnd BAM. Effect achieved.

Not really fully do-able in CSS until they get the lil bit of scriptability built into the language.

You can do this by using CSS: JSFiddle

HTML:

<select>
    <option>Text 1</option>
    <option>Text 2</option>
    <option>Text 3</option>
</select>

CSS:

select option:first-child { color:red; }

Or if you absolutely need to use JavaScript (not adviced for this): JSFiddle

JavaScript:

$(function() {
    $("select option:first-child").addClass("highlight");
});

CSS:

.highlight { color:red; }

Just reference the variable inside the function; no magic, just use it's name. If it's been created globally, then you'll be updating the global variable.

You can override this behaviour by declaring it locally using var, but if you don't use var, then a variable name used in a function will be global if that variable has been declared globally.

That's why it's considered best practice to always declare your variables explicitly with var. Because if you forget it, you can start messing with globals by accident. It's an easy mistake to make. But in your case, this turn around and becomes an easy answer to your question.

Your folder/file structure seems a little odd to me. I can't quite figure out how you've got this laid out.

Hello I am using CodeIgniter for two applications (a public and an admin app).

This sounds to me like you've got two separate CI installations. If this is the case, I'd recommend against it. Why not just handle all admin stuff in an admin controller? If you do want two separate CI installations, make sure they are definitely distinct entities and that the two aren't conflicting with one another. This line:

$system_folder = "../system";
$application_folder = "../application/admin"; (this line exists of course twice)

And the place you said this exists (/admin/index.php...or did you mean /admin/application/config?) has me scratching my head. You have admin/application/admin and a system folder at the top level?

You can use list comprehensions for this problem as it will solve it in only two lines. Code-

n = int(input("Enter the range of the list:\n"))
l1 = [i for i in range(n)] #Creates list of numbers in the range 0 to n
if __name__ == "__main__":
    print(l1)

Thank you.

I think it's worth putting a few timings up here for some perspective.

All timings done on OS-X 10.5.8 with python2.7

John Clement's answer:

python -m timeit -s 'my_list = range(1000)[::-1]; from operator import itemgetter' 'min(enumerate(my_list),key=itemgetter(1))'
1000 loops, best of 3: 239 usec per loop    

David Wolever's answer:

python -m timeit -s 'my_list = range(1000)[::-1]' 'min((val, idx) for (idx, val) in enumerate(my_list))
1000 loops, best of 3: 345 usec per loop

OP's answer:

python -m timeit -s 'my_list = range(1000)[::-1]' 'my_list.index(min(my_list))'
10000 loops, best of 3: 96.8 usec per loop

Note that I'm purposefully putting the smallest item last in the list to make .index as slow as it could possibly be. It would be interesting to see at what N the iterate once answers would become competitive with the iterate twice answer we have here.

Of course, speed isn't everything and most of the time, it's not even worth worrying about ... choose the one that is easiest to read unless this is a performance bottleneck in your code (and then profile on your typical real-world data -- preferably on your target machines).

Following on @Kire Haglin's answer, a further example of generics methods can be seen in the documentation for JAXB unmarshalling:

public <T> T unmarshal( Class<T> docClass, InputStream inputStream )
         throws JAXBException {
  String packageName = docClass.getPackage().getName();
  JAXBContext jc = JAXBContext.newInstance( packageName );
  Unmarshaller u = jc.createUnmarshaller();
  JAXBElement<T> doc = (JAXBElement<T>)u.unmarshal( inputStream );
  return doc.getValue();
}

This allows unmarshal to return a document of an arbitrary JAXB content tree type.

As of current edited version of the post, you call setInterval at each change's end, adding a new "changer" with each new iterration. That means after first run, there's one of them ticking in memory, after 100 runs, 100 different changers change image 100 times every second, completely destroying performance and producing confusing results.

You only need to "prime" setInterval once. Remove it from function and place it inside onload instead of direct function call.

I successfully opened gstreamer SDK tutorials in Eclipse.

All I needed is to use an older version of ndk. specificly 9d.

(10c and 10d does not work, 10b - works just for tutorial-1 )

9d does work for all tutorials ! and you can:

1. Download it from: http://dl.google.com/android/ndk/android-ndk-r9d-linux-x86_64.tar.bz2

2. Extract it.

3. set it in eclipse->window->preferences->Android->NDK->NDK location.

4. build - (ctrl+b).

You will have to use the fluent API to do this.

Try adding the following to your DbContext:

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{   
    modelBuilder.Entity<User>()
        .HasOptional(a => a.UserDetail)
        .WithOptionalDependent()
        .WillCascadeOnDelete(true);
}

If you're on the Model Overview page you get a tab with the schema. If you rightclick on that tab you get an option to "edit schema". From there you can rename the schema by adding a new name, then click outside the field. This goes for MySQL Workbench 5.2.30 CE

Edit: On the model overview it's under Physical Schemata

Screenshot:

The command clause does work as @Karthik says above.

As a simple example, the following service will have a -inMemory added to its ENTRYPOINT when docker-compose up is run.

version: '2'
services:
  local-dynamo:
    build: local-dynamo
    image: spud/dynamo
    command: -inMemory

impossible with javascript. Just as another alternative to suggestions from other answers: consider using jGrowl: http://archive.plugins.jquery.com/project/jGrowl

BIT should only allow 0 and 1 (and NULL, if the field is not defined as NOT NULL). TINYINT(1) allows any value that can be stored in a single byte, -128..127 or 0..255 depending on whether or not it's unsigned (the 1 shows that you intend to only use a single digit, but it does not prevent you from storing a larger value).

For versions older than 5.0.3, BIT is interpreted as TINYINT(1), so there's no difference there.

BIT has a "this is a boolean" semantic, and some apps will consider TINYINT(1) the same way (due to the way MySQL used to treat it), so apps may format the column as a check box if they check the type and decide upon a format based on that.

<meta http-equiv="refresh" content="5; url=http://example.com/">

shouldn't the button be 100% width if it's "display: block"

No. That just means it's the only thing in the space vertically (assuming you aren't using another trick to force something else there as well). It doesn't mean it has to fill up the width of that space.

I think your problem in this instance is that the input is not natively a block element. Try nesting it inside another div and set the margin on that. But I don't have an IE8 browser to test this with at the moment, so it's just a guess.

from the command line: for /R /D %1 in (*) do rd "%1"

in a batch file for /R /D %%1 in (*) do rd "%%1"

I don't know if it's documented as such, but it works in W2K, XP, and Win 7. And I don't know if it will always work, but it won't ever delete files by accident.

This is an old question. Not sure when support became more broad, but getAllResponseHeaders() and getResponseHeader() appear to now be fairly standard: http://www.w3schools.com/xml/dom_http.asp

if the link element is:

<a id="misc" href="#misc">Miscellaneous</a>

and the Miscellaneous category is bounded by something like:

<p id="miscCategory" name="misc">....</p>

you can use jQuery to do the desired effect:

<script type="text/javascript">
  $("#misc").click(function() {
    $("#miscCategory").animate({scrollTop: $("#miscCategory").offset().top});
  });
</script>

as far as I remember it correctly.. (though, I haven't tested it and wrote it from memory)

@JavaZava your solution is good, but if you want to have a 13 digit long value to be consistent with the time stamp formatting in Java or JavaScript (and other languages) use this method:

NSTimeInterval time = ([[NSDate date] timeIntervalSince1970]); // returned as a double
long digits = (long)time; // this is the first 10 digits
int decimalDigits = (int)(fmod(time, 1) * 1000); // this will get the 3 missing digits
long timestamp = (digits * 1000) + decimalDigits;

or (if you need a string):

NSString *timestampString = [NSString stringWithFormat:@"%ld%d",digits ,decimalDigits];

The issue is that you're not saving the mysqli connection. Change your connect to:

$aVar = mysqli_connect('localhost','tdoylex1_dork','dorkk','tdoylex1_dork');

And then include it in your query:

$query1 = mysqli_query($aVar, "SELECT name1 FROM users
    ORDER BY RAND()
    LIMIT 1");
$aName1 = mysqli_fetch_assoc($query1);
$name1 = $aName1['name1'];

Also don't forget to enclose your connections variables as strings as I have above. This is what's causing the error but you're using the function wrong, mysqli_query returns a query object but to get the data out of this you need to use something like mysqli_fetch_assoc http://php.net/manual/en/mysqli-result.fetch-assoc.php to actually get the data out into a variable as I have above.

You have to define a PersistentVolume providing disc space to be consumed by the PersistentVolumeClaim.

When using storageClass Kubernetes is going to enable "Dynamic Volume Provisioning" which is not working with the local file system.

To solve your issue:

• Provide a PersistentVolume fulfilling the constraints of the claim (a size >= 100Mi)
• Remove the storageClass-line from the PersistentVolumeClaim
• Remove the StorageClass from your cluster

How do these pieces play together?

At creation of the deployment state-description it is usually known which kind (amount, speed, ...) of storage that application will need.
To make a deployment versatile you'd like to avoid a hard dependency on storage. Kubernetes' volume-abstraction allows you to provide and consume storage in a standardized way.

The PersistentVolumeClaim is used to provide a storage-constraint alongside the deployment of an application.

The PersistentVolume offers cluster-wide volume-instances ready to be consumed ("bound"). One PersistentVolume will be bound to one claim. But since multiple instances of that claim may be run on multiple nodes, that volume may be accessed by multiple nodes.

A PersistentVolume without StorageClass is considered to be static.

"Dynamic Volume Provisioning" alongside with a StorageClass allows the cluster to provision PersistentVolumes on demand. In order to make that work, the given storage provider must support provisioning - this allows the cluster to request the provisioning of a "new" PersistentVolume when an unsatisfied PersistentVolumeClaim pops up.

Example PersistentVolume

In order to find how to specify things you're best advised to take a look at the API for your Kubernetes version, so the following example is build from the API-Reference of K8S 1.17:

apiVersion: v1
kind: PersistentVolume
metadata:
  name: ckan-pv-home
  labels:
    type: local
spec:
  capacity:
    storage: 100Mi
  hostPath:
    path: "/mnt/data/ckan"

The PersistentVolumeSpec allows us to define multiple attributes. I chose a hostPath volume which maps a local directory as content for the volume. The capacity allows the resource scheduler to recognize this volume as applicable in terms of resource needs.

Additional Resources:

• Configure PersistentVolume Guide

Rather than Runtime.exec(String command), you need to use the exec(String command, String[] envp, File dir) method signature:

Process p =  Runtime.getRuntime().exec("cmd /c upsert.bat", null, new File("C:\\Program Files\\salesforce.com\\Data Loader\\cliq_process\\upsert"));

But personally, I'd use ProcessBuilder instead, which is a little more verbose but much easier to use and debug than Runtime.exec().

ProcessBuilder pb = new ProcessBuilder("cmd", "/c", "upsert.bat");
File dir = new File("C:/Program Files/salesforce.com/Data Loader/cliq_process/upsert");
pb.directory(dir);
Process p = pb.start();

var elem = document.getElementById('mytest1');

// Simulate clicking on the specified element.
triggerEvent( elem, 'click' );

/**
 * Trigger the specified event on the specified element.
 * @param  {Object} elem  the target element.
 * @param  {String} event the type of the event (e.g. 'click').
 */
function triggerEvent( elem, event ) {
  var clickEvent = new Event( event ); // Create the event.
  elem.dispatchEvent( clickEvent );    // Dispatch the event.
}

A memory heap is a common structure for holding dynamically allocated memory. See Dynamic_memory_allocation on wikipedia.

There are other structures, like pools, stacks and piles.

You've probably miss-typed something above that bit of code or created your own class called IPAddress. If you're using the .net one, that function should be available.

Have you tried using System.Net.IPAddress just in case?

System.Net.IPAddress ipaddress = System.Net.IPAddress.Parse("127.0.0.1");  //127.0.0.1 as an example

The docs on Microsoft's site have a complete example which works fine on my machine.

If you use eclipse, maybe PyUML. Haven't used it, though.

The answer below takes some extra cycles, but it is another method

def func(tup):
    return tup[-1]


def print_words(filename):
    f = open("small.txt",'r')
    whole_content = (f.read()).lower()
    print whole_content
    list_content = whole_content.split()
    dict = {}
    for one_word in list_content:
        dict[one_word] = 0
    for one_word in list_content:
        dict[one_word] += 1
    print dict.items()
    print sorted(dict.items(),key=func)

If, by any change, you are in an application which already uses http://restfb.com/ then you can do:

import com.restfb.json.JsonObject;

...

JsonObject json = new JsonObject(jsonString);
json.get("title");

etc.

UPDATE: Plunkr added

I was looking for a solution on all forums but found none, so found a solution with Old School Javascript Callback function. This is a really simple and clean way to create a confirmation dialog and set Callback functions for both YES and NO click events.
I have used Bootstrap CSS for Modal and An Alert Service with rxjs Subject.

alert.component.html

        <div *ngIf="message.type == 'confirm'"  class="modal-body">
            <div class="row">
                <div class="col-md-12">
                    <h3 class="text-center">{{message.text}}</h3>
                </div>
            </div>
            <div class="row">
                <div class="col-md-12">
                    <p class="text-center">
                        <a (click)="message.noFn()">
                            <button class="btn btn-pm">No</button>
                        </a>
                        <a (click)="message.siFn()">
                            <button  class="btn btn-sc" >Yes</button>
                        </a>
                    </p>
                </div>
            </div>
         </div>

alert.component.ts

export class AlertComponent {
    message: any;
    constructor(
      public router: Router, 
      private route: ActivatedRoute, 
      private alertService: AlertService,
   ) { }
   ngOnInit() {
    //this function waits for a message from alert service, it gets 
    //triggered when we call this from any other component
    this.alertService.getMessage().subscribe(message => {
        this.message = message;
    });
}

The most important part is here alert.service.ts

     import { Injectable } from '@angular/core'; 
     import { Router, NavigationStart } from '@angular/router'; 
     import { Observable } from 'rxjs'; 
     import { Subject } from 'rxjs/Subject';
     @Injectable() export class AlertService {
          private subject = new Subject<any>();
          constructor(){}
          confirm(message: string,siFn:()=>void,noFn:()=>void){
            this.setConfirmation(message,siFn,noFn);
          }
          setConfirmation(message: string,siFn:()=>void,noFn:()=>void) {
            let that = this;
            this.subject.next({ type: "confirm",
                        text: message,
                        siFn:
                        function(){
                            that.subject.next(); //this will close the modal
                            siFn();
                        },
                        noFn:function(){
                            that.subject.next();
                            noFn();
                        }
                     });

                 }

          getMessage(): Observable<any> {
             return this.subject.asObservable();
          }
       }

Call the function from any component

this.alertService.confirm("You sure Bro?",function(){
    //ACTION: Do this If user says YES
},function(){
    //ACTION: Do this if user says NO
})

This error would happen when the number of guesses (so_far) is less than the length of the word. Did you miss an initialization for the variable so_far somewhere, that sets it to something like

so_far = " " * len(word)

?

Edit:

try something like

print "%d / %d" % (new, so_far)

before the line that throws the error, so you can see exactly what goes wrong. The only thing I can think of is that so_far is in a different scope, and you're not actually using the instance you think.

In Ruby and other languages that support POSIX character classes in bracket expressions, you can do simply:

/\A[[:alpha:]]+\z/i

That will match alpha-chars in all Unicode alphabet languages. Easy peasy.

If you only want the first element of a set (and you are certain there is at least one element) you can do the following:

<c:choose>
    <c:when test="${dealership.administeredBy.size() == 1}">
        Hello ${dealership.administeredBy.iterator().next().firstName},<br/>
    </c:when>
    <c:when test="${dealership.administeredBy.size() > 1}">
        Hello Administrators,<br/>
    </c:when>
    <c:otherwise>
    </c:otherwise>
</c:choose>
