After reviewing MySQL 5.7 changes, MySql stopped supporting zero values in date / datetime.

It's incorrect to use zeros in date or in datetime, just put null instead of zeros.

This is what helped me:

1. Create a new branch with the existing one. Let's call the existing one branch_old and new as branch_new.

2. Reset branch_new to a stable state, when you did not have any problem commit at all. For example, to put it at your local master's level do the following:

   git reset —hard master git push —force origin

3. cherry-pick the commits from branch_old into branch_new

4. git push

Check this one. It will work.

function fetch($i1,$i2,$i3,$i4)
{
$input_data = '<I> 
                <i1>'.$i1.'</i1> 
                <i2>'.$i2.'</i2> 
                <i3>'.$i2.'</i3> 
                <i4>'.$i3.'</i4> 
              </I>';
$curl = curl_init();

curl_setopt_array($curl, array(
  CURLOPT_PORT => "8080",
  CURLOPT_URL => "http://192.168.1.100:8080/avaliablity",
  CURLOPT_RETURNTRANSFER => true,

  CURLOPT_TIMEOUT => 30,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => "POST",
  CURLOPT_POSTFIELDS => $input_data,
  CURLOPT_HTTPHEADER => array(
    "Cache-Control: no-cache",
    "Content-Type: application/xml"
  ),
));

$response = curl_exec($curl);
$err = curl_error($curl);

curl_close($curl);

if ($err) {
  echo "cURL Error #:" . $err;
} else {
  echo $response;
}
}

fetch('i1','i2','i3','i4');

When you have everything #included, an unresolved external symbol is often a missing * or & in the declaration or definition of a function.

I think the only cookie you need is JSESSIONID=xxx..

Also NEVER share your cookies, becasuse someone may access your personal data that way. Specially when the cookies are session. These cookies will stop working once you logout the site.

You're missing a reference to System.Linq.

Add

using System.Linq

to get access to the ToList() function on the current code file.

To give a little bit of information over why this is necessary, Enumerable.ToList<TSource> is an extension method. Extension methods are defined outside the original class that it targets. In this case, the extension method is defined on System.Linq namespace.

This is a template for a function decorator that does not require () if no parameters are to be given:

import functools


def decorator(x_or_func=None, *decorator_args, **decorator_kws):
    def _decorator(func):
        @functools.wraps(func)
        def wrapper(*args, **kws):
            if 'x_or_func' not in locals() \
                    or callable(x_or_func) \
                    or x_or_func is None:
                x = ...  # <-- default `x` value
            else:
                x = x_or_func
            return func(*args, **kws)

        return wrapper

    return _decorator(x_or_func) if callable(x_or_func) else _decorator

an example of this is given below:

def multiplying(factor_or_func=None):
    def _decorator(func):
        @functools.wraps(func)
        def wrapper(*args, **kwargs):
            if 'factor_or_func' not in locals() \
                    or callable(factor_or_func) \
                    or factor_or_func is None:
                factor = 1
            else:
                factor = factor_or_func
            return factor * func(*args, **kwargs)
        return wrapper
    return _decorator(factor_or_func) if callable(factor_or_func) else _decorator

What are you expecting? The default Tomcat homepage? If so, you'll need to configure Eclipse to take control over from Tomcat.

Doubleclick the Tomcat server entry in the Servers tab, you'll get the server configuration. At the left column, under Server Locations, select Use Tomcat installation (note, when it is grayed out, read the section leading text! ;) ). This way Eclipse will take full control over Tomcat, this way you'll also be able to access the default Tomcat homepage with the Tomcat Manager when running from inside Eclipse. I only don't see how that's useful while developing using Eclipse.

The port number is not the problem. You would otherwise have gotten an exception in Tomcat's startup log, and the browser would show a browser-specific "Connection timed out" error page and thus not a Tomcat-specific error page which could impossibly be served when Tomcat was not up and running.

I had the same issue. I deleted the .git folder then followed the following commands

1. $ git init
2. $ git add .
3. $ git remote add origin [email protected]:project/project.git
4. $ git commit -m "Initial version"
5. $ git push origin master

res.next() method will take the pointer to the next row. and in your code you are using it twice, first for the if condition (cursor moves to first row) then for while condition (cursor moves to second row).

So when you access your results, it starts from second row. So shows one row less in results.

you can try this :

if(!res.next()){ 
    System.out.println("No Data Found");  
}
else{
    do{
       //your code
    } 
    while(res.next());
}

In Excel 2010 it is easy, just takes a few more steps for each list items.

The following steps must be completed for each item within the validation list. (Have the worksheet open to where the drop down was created)

1) Click on cell with drop down list.
2) Select which answer to apply format to.
3) Click on "Home" tab, then click the "Styles" tool button on the ribbon.
4) Click "Conditional Formatting", in drop down list click the "*New Rule" option.
5) Select a Rule Type: "Format only cells that contain"
6) Edit the Rule Description: "Cell Value", "equal to", click the cell formula icon in the formula bar (far right), select which worksheet the validation list was created in, select the cell within the list to which you wish to apply the formatting.

Formula should look something like: ='Workbook Data'!$A$2

7) Click the formula icon again to return to format menu.
8) Click on Format button beside preview pane.
9) Select all format options desired.
10) Press "OK" twice.

You are finished with only one item within list. Repeat steps 1 thru 10 until all drop down list items are finished.

Yes, the best practice is to check-in (YES, CHECK-IN)

I agree that it will cause a lot of noise or conflict when seeing the diff. But the benefits are:

1. guarantee exact same version of every package. This part is the most important when building in different environments at different times. You may use ^1.2.3 in your package.json, but how can u ensure each time npm install will pick up the same version in your dev machine and in the build server, especially those indirect dependency packages? Well, package-lock.json will ensure that. (With the help of npm ci which installs packages based on lock file)
2. it improves the installation process.
3. it helps with new audit feature npm audit fix (I think the audit feature is from npm version 6).

Following are eight ways to find the Uptime in Windows OS.

1: By using the Task Manager

In Windows Vista and Windows Server 2008, the Task Manager has been beefed up to show additional information about the system. One of these pieces of info is the server’s running time.

1. Right-click on the Taskbar, and click Task Manager. You can also click CTRL+SHIFT+ESC to get to the Task Manager.
2. In Task Manager, select the Performance tab.

3. The current system uptime is shown under System or Performance ⇒ CPU for Win 8/10.

   

2: By using the System Information Utility

The systeminfo command line utility checks and displays various system statistics such as installation date, installed hotfixes and more. Open a Command Prompt and type the following command:

systeminfo

You can also narrow down the results to just the line you need:

systeminfo | find "System Boot Time:"

3: By using the Uptime Utility

Microsoft have published a tool called Uptime.exe. It is a simple command line tool that analyses the computer's reliability and availability information. It can work locally or remotely. In its simple form, the tool will display the current system uptime. An advanced option allows you to access more detailed information such as shutdown, reboots, operating system crashes, and Service Pack installation.

Read the following KB for more info and for the download links:

• MSKB232243: Uptime.exe Tool Allows You to Estimate Server Availability with Windows NT 4.0 SP4 or Higher.

To use it, follow these steps:

1. Download uptime.exe from the above link, and save it to a folder, preferably in one that's in the system's path (such as SYSTEM32).
2. Open an elevated Command Prompt window. To open an elevated Command Prompt, click Start, click All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator. You can also type CMD in the search box of the Start menu, and when you see the Command Prompt icon click on it to select it, hold CTRL+SHIFT and press ENTER.
3. Navigate to where you've placed the uptime.exe utility.
4. Run the uptime.exe utility. You can add a /? to the command in order to get more options.

It does not offer many command line parameters:

C:\uptimefromcodeplex\> uptime /?
usage: Uptime [-V]
    -V   display version

C:\uptimefromcodeplex\> uptime -V
version 1.1.0

3.1: By using the old Uptime Utility

There is an older version of the "uptime.exe" utility. This has the advantage of NOT needing .NET. (It also has a lot more features beyond simple uptime.)

Download link: Windows NT 4.0 Server Uptime Tool (uptime.exe) (final x86)

C:\uptimev100download>uptime.exe /?

UPTIME, Version 1.00
(C) Copyright 1999, Microsoft Corporation

Uptime [server] [/s ] [/a] [/d:mm/dd/yyyy | /p:n] [/heartbeat] [/? | /help]
        server          Name or IP address of remote server to process.
        /s              Display key system events and statistics.
        /a              Display application failure events (assumes /s).
        /d:             Only calculate for events after mm/dd/yyyy.
        /p:             Only calculate for events in the previous n days.
        /heartbeat      Turn on/off the system's heartbeat
        /?              Basic usage.
        /help           Additional usage information.

4: By using the NET STATISTICS Utility

Another easy method, if you can remember it, is to use the approximate information found in the statistics displayed by the NET STATISTICS command. Open a Command Prompt and type the following command:

net statistics workstation

The statistics should tell you how long it’s been running, although in some cases this information is not as accurate as other methods.

5: By Using the Event Viewer

Probably the most accurate of them all, but it does require some clicking. It does not display an exact day or hour count since the last reboot, but it will display important information regarding why the computer was rebooted and when it did so. We need to look at Event ID 6005, which is an event that tells us that the computer has just finished booting, but you should be aware of the fact that there are virtually hundreds if not thousands of other event types that you could potentially learn from.

Note: BTW, the 6006 Event ID is what tells us when the server has gone down, so if there’s much time difference between the 6006 and 6005 events, the server was down for a long time.

Note: You can also open the Event Viewer by typing eventvwr.msc in the Run command, and you might as well use the shortcut found in the Administrative tools folder.

2. Click on Event Viewer (Local) in the left navigation pane.
3. In the middle pane, click on the Information event type, and scroll down till you see Event ID 6005. Double-click the 6005 Event ID, or right-click it and select View All Instances of This Event.
4. A list of all instances of the 6005 Event ID will be displayed. You can examine this list, look at the dates and times of each reboot event, and so on.
5. Open Server Manager tool by right-clicking the Computer icon on the start menu (or on the Desktop if you have it enabled) and select Manage. Navigate to the Event Viewer.

5.1: Eventlog via PowerShell

Get-WinEvent -ProviderName eventlog | Where-Object {$_.Id -eq 6005 -or $_.Id -eq 6006}

6: Programmatically, by using GetTickCount64

GetTickCount64 retrieves the number of milliseconds that have elapsed since the system was started.

7: By using WMI

wmic os get lastbootuptime

8: The new uptime.exe for Windows XP and up

Like the tool from Microsoft, but compatible with all operating systems up to and including Windows 10 and Windows Server 2016, this uptime utility does not require an elevated command prompt and offers an option to show the uptime in both DD:HH:MM:SS and in human-readable formats (when executed with the -h command-line parameter).

Additionally, this version of uptime.exe will run and show the system uptime even when launched normally from within an explorer.exe session (i.e. not via the command line) and pause for the uptime to be read:

and when executed as uptime -h:

You may be trying to use a JSON object:

var myMappings = { "name": "10%", "phone": "10%", "address": "50%", etc.. }

To access:

myMappings.name;
myMappings.phone;
etc..

The simplest solution is: Create a CSS file and type this:

.btn:focus, .btn:active:focus, .btn.active:focus {
    box-shadow: none !important;
}

For me the tricky part was figuring out the transformation function between the two axis. I used myCurveFit for that.

Finding the transformation function

1. y1 --> y2 This function is used to transform the data of the secondary y axis to be "normalized" according to the first y axis

transformation function: f(y1) = 0.025*x + 2.75

2. y2 --> y1 This function is used to transform the break points of the first y axis to the values of the second y axis. Note that the axis are swapped now.

transformation function: f(y1) = 40*x - 110

Plotting

Note how the transformation functions are used in the ggplot call to transform the data "on-the-fly"

ggplot(data=combined_80_8192 %>% filter (time > 270, time < 280), aes(x=time) ) +
  stat_summary(aes(y=receivedPower_dbm ), fun.y=mean, geom="line", colour="black") +
  stat_summary(aes(y=packetOkSinr*40 - 110 ), fun.y=mean, geom="line", colour="black", position = position_dodge(width=10)) +
  scale_x_continuous() +
  scale_y_continuous(breaks = seq(-0,-110,-10), "y_first", sec.axis=sec_axis(~.*0.025+2.75, name="y_second") ) 

The first stat_summary call is the one that sets the base for the first y axis. The second stat_summary call is called to transform the data. Remember that all of the data will take as base the first y axis. So that data needs to be normalized for the first y axis. To do that I use the transformation function on the data: y=packetOkSinr*40 - 110

Now to transform the second axis I use the opposite function within the scale_y_continuous call: sec.axis=sec_axis(~.*0.025+2.75, name="y_second").

If you want to hide just the axis text keeping the grid lines:

frame1 = plt.gca()
frame1.axes.xaxis.set_ticklabels([])
frame1.axes.yaxis.set_ticklabels([])

Doing set_visible(False) or set_ticks([]) will also hide the grid lines.

http: //localhost:8080/web

Where

• localhost ( hostname ) is the machine name or IP address of the host server e.g Glassfish, Tomcat.
• 8080 ( port ) is the address of the port on which the host server is listening for requests.

http ://localhost/web

Where

• localhost ( hostname ) is the machine name or IP address of the host server e.g Glassfish, Tomcat.
• host server listening to default port 80.

You can use CAST and CONVERT to switch between different types of encodings. See: http://dev.mysql.com/doc/refman/5.0/en/charset-convert.html

SELECT column1, CONVERT(column2 USING utf8)
FROM my_table 
WHERE my_condition;

If your "boolean" variable comes from a global array such as $_POST and $_GET, you can use filter_input() filter function.

Example for POST:

$isSleeping  = filter_input(INPUT_POST, 'is_sleeping',  FILTER_VALIDATE_BOOLEAN);

If your "boolean" variable comes from other source you can use filter_var() filter function.

Example:

filter_var('true', FILTER_VALIDATE_BOOLEAN); // true

I had a slightly augmented issue. I needed to rename a machine and then RE-JOIN a domain it was already a member of and could not find where to do that but its seems very close to what is here. The individual solutions above don't do it but with some togetherness... If you try to rename, you get denied. If you rename and then rejoin, you get an account already exists error. You need to bail from the domain by joining a workgroup and then you can run the rename and join in one command.

$Chops = Get-Credential 
# Or bring in a stored credential
$NewComputerName = "WhoImGonnaBe" 
# or value from CSV
$MyDomainName = "MyDomain"
Add-Computer -WorkgroupName NotADomain -force -DomainCredential $Chops
Add-Computer -DomainName $MyDomainName -Computername $ENV:Computername -NewName $NewComputerName -DomainCredential $Chops -Force -Restart
#  If running locally you really only need the -NewName and can omit the -Computername

Use the -i option:

ssh -i mykey.pem [email protected]

As noted in this answer, this file needs to have correct permissions set. The ssh man page says:

ssh will simply ignore a private key file if it is accessible by others.

You can change the permissions with this command:

chmod go= mykey.pem

That is, set permissions for group and others equal to the empty list of permissions.

SQL Server does not have a TRIM function, but rather it has two. One each for specifically trimming spaces from the "front" of a string (LTRIM) and one for trimming spaces from the "end" of a string (RTRIM).

Something like the following will update every record in your table, trimming all extraneous space (either at the front or the end) of a varchar/nvarchar field:

UPDATE 
   [YourTableName]
SET
   [YourFieldName] = LTRIM(RTRIM([YourFieldName]))

(Strangely, SSIS (Sql Server Integration Services) does have a single TRIM function!)

Mozilla:

MozillaProductSlice. Claims to be a Mozilla based user agent, which is only true for Gecko browsers like Firefox and Netscape. For all other user agents it means 'Mozilla-compatible'. In modern browsers, this is only used for historical reasons. It has no real meaning anymore

I'm using Spring Boot 2.0.4.RELEASE. Hikari is default connection pool and .hikari is no longer necessary.

application.properties

spring.datasource.driverClassName=com.mysql.jdbc.Driver
spring.datasource.jdbcUrl=jdbc:mysql://localhost:3306/myDB...
spring.datasource.username=xxx
spring.datasource.password=xxx
spring.datasource.poolname=myPool

application.yml

spring:
    datasource:
        driverClassName: com.mysql.jdbc.Driver
        jdbcUrl: jdbc:mysql://localhost:3306/myDB...
        username: xxx
        password: xxx
        poolName: myPool

And configuration does not need to extend HikariConfig, and DataSourceBuilder can be used as it was before.

@Configuration
public class DataSourceConfiguration {

    @Bean(name="myDataSource")
    @ConfigurationProperties("spring.datasource")
    public DataSource myDataSource() {
        return DataSourceBuilder.create().build();
    }
}

To read a line or a string, you can use a BufferedReader object combined with an InputStreamReader one as follows:

BufferedReader bufferReader = new BufferedReader(new InputStreamReader(System.in));
String inputLine = bufferReader.readLine();

Below is the more accurate query. I am giving example how to convert it to utf8

SELECT CONCAT("ALTER TABLE `", TABLE_NAME,"` DEFAULT CHARACTER SET utf8 COLLATE utf8_unicode_ci;") AS    mySQL
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_SCHEMA="myschema"
AND TABLE_TYPE="BASE TABLE"

you can filter the waypoints by passing the user to the form init

class waypointForm(forms.Form):
    def __init__(self, user, *args, **kwargs):
        super(waypointForm, self).__init__(*args, **kwargs)
        self.fields['waypoints'] = forms.ChoiceField(
            choices=[(o.id, str(o)) for o in Waypoint.objects.filter(user=user)]
        )

from your view while initiating the form pass the user

form = waypointForm(user)

in case of model form

class waypointForm(forms.ModelForm):
    def __init__(self, user, *args, **kwargs):
        super(waypointForm, self).__init__(*args, **kwargs)
        self.fields['waypoints'] = forms.ModelChoiceField(
            queryset=Waypoint.objects.filter(user=user)
        )

    class Meta:
        model = Waypoint

You can get current year, month, day etc from a calendar instance

val c = Calendar.getInstance()

val year = c.get(Calendar.YEAR)
val month = c.get(Calendar.MONTH)
val day = c.get(Calendar.DAY_OF_MONTH)

val hour = c.get(Calendar.HOUR_OF_DAY)
val minute = c.get(Calendar.MINUTE)

If you need it as a LocalDateTime, simply create it by using the parameters you got above

val myLdt = LocalDateTime.of(year, month, day, ... )

A more generic solution for might be the following.

    extendDf <- function (df, n) {
    withFactors <- sum(sapply (df, function(X) (is.factor(X)) )) > 0
    nr          <- nrow (df)
    colNames    <- names(df)
    for (c in 1:length(colNames)) {
        if (is.factor(df[,c])) {
            col         <- vector (mode='character', length = nr+n) 
            col[1:nr]   <- as.character(df[,c])
            col[(nr+1):(n+nr)]<- rep(col[1], n)  # to avoid extra levels
            col         <- as.factor(col)
        } else {
            col         <- vector (mode=mode(df[1,c]), length = nr+n)
            class(col)  <- class (df[1,c])
            col[1:nr]   <- df[,c] 
        }
        if (c==1) {
            newDf       <- data.frame (col ,stringsAsFactors=withFactors)
        } else {
            newDf[,c]   <- col 
        }
    }
    names(newDf) <- colNames
    newDf
}

The function extendDf() extends a data frame with n rows.

As an example:

aDf <- data.frame (l=TRUE, i=1L, n=1, c='a', t=Sys.time(), stringsAsFactors = TRUE)
extendDf (aDf, 2)
#      l i n c                   t
# 1  TRUE 1 1 a 2016-07-06 17:12:30
# 2 FALSE 0 0 a 1970-01-01 01:00:00
# 3 FALSE 0 0 a 1970-01-01 01:00:00

system.time (eDf <- extendDf (aDf, 100000))
#    user  system elapsed 
#   0.009   0.002   0.010
system.time (eDf <- extendDf (eDf, 100000))
#    user  system elapsed 
#   0.068   0.002   0.070

XSLT 1.0 does not have an integer data type, only double. You can use number() to convert a string to a number.

In my case this error is happening because of not connected to firebase firestore but using the same.

To rectify the issue please go to Tools-> Firebase

A simple way to do it without the use of such a complicated draw statement:

    //Make a backup so that we can reset our graphics object after using it.
    AffineTransform backup = g2d.getTransform();
    //rx is the x coordinate for rotation, ry is the y coordinate for rotation, and angle
    //is the angle to rotate the image. If you want to rotate around the center of an image,
    //use the image's center x and y coordinates for rx and ry.
    AffineTransform a = AffineTransform.getRotateInstance(angle, rx, ry);
    //Set our Graphics2D object to the transform
    g2d.setTransform(a);
    //Draw our image like normal
    g2d.drawImage(image, x, y, null);
    //Reset our graphics object so we can draw with it again.
    g2d.setTransform(backup);

The better way is using 'background-size'.

.pnx-msg-icon .pnx-icon-msg-warning{
background-image: url("../pics/edit.png");
background-repeat: no-repeat;
background-size: 10px;
width: 10px;
height: 10px;
cursor: pointer;
}

even if your icon dimensions is bigger than 10px it will be 10px.

You can use the MATCH_PARENT constant or its numeric value -1.

Alongside nmaier's answer, as he said you'll always receive code 1006. However, if you were to somehow theoretically receive other codes, here is code to display the results (via RFC6455).

A merge vim will open. Add some merging message and:

1. Press ESC
2. Press Shift + ';'
3. Press 'w' and then press 'q'.

And you are good to go.

CSS selectors perform far better than Xpath and it is well documented in Selenium community. Here are some reasons,

• Xpath engines are different in each browser, hence make them inconsistent
• IE does not have a native xpath engine, therefore selenium injects its own xpath engine for compatibility of its API. Hence we lose the advantage of using native browser features that WebDriver inherently promotes.
• Xpath tend to become complex and hence make hard to read in my opinion

However there are some situations where, you need to use xpath, for example, searching for a parent element or searching element by its text (I wouldn't recommend the later).

You can read blog from Simon here . He also recommends CSS over Xpath.

If you are testing content then do not use selectors that are dependent on the content of the elements. That will be a maintenance nightmare for every locale. Try talking with developers and use techniques that they used to externalize the text in the application, like dictionaries or resource bundles etc. Here is my blog that explains it in detail.

edit 1

Thanks to @parishodak, here is the link which provides the numbers proving that CSS performance is better

You can use the code below:

document.body.addEventListener('click', function (evt) {
    if (evt.target.className === 'databox') {

Capturing and grouping

Capturing group (pattern) creates a group that has capturing property.

A related one that you might often see (and use) is (?:pattern), which creates a group without capturing property, hence named non-capturing group.

A group is usually used when you need to repeat a sequence of patterns, e.g. (\.\w+)+, or to specify where alternation should take effect, e.g. ^(0*1|1*0)$ (^, then 0*1 or 1*0, then $) versus ^0*1|1*0$ (^0*1 or 1*0$).

A capturing group, apart from grouping, will also record the text matched by the pattern inside the capturing group (pattern). Using your example, (.*):, .* matches ABC and : matches :, and since .* is inside capturing group (.*), the text ABC is recorded for the capturing group 1.

Group number

The whole pattern is defined to be group number 0.

Any capturing group in the pattern start indexing from 1. The indices are defined by the order of the opening parentheses of the capturing groups. As an example, here are all 5 capturing groups in the below pattern:

(group)(?:non-capturing-group)(g(?:ro|u)p( (nested)inside)(another)group)(?=assertion)
|     |                       |          | |      |      ||       |     |
1-----1                       |          | 4------4      |5-------5     |
                              |          3---------------3              |
                              2-----------------------------------------2

The group numbers are used in back-reference \n in pattern and $n in replacement string.

^{In other regex flavors (PCRE, Perl), they can also be used in sub-routine calls.}

You can access the text matched by certain group with Matcher.group(int group). The group numbers can be identified with the rule stated above.

^{In some regex flavors (PCRE, Perl), there is a branch reset feature which allows you to use the same number for capturing groups in different branches of alternation.}

Group name

From Java 7, you can define a named capturing group (?<name>pattern), and you can access the content matched with Matcher.group(String name). The regex is longer, but the code is more meaningful, since it indicates what you are trying to match or extract with the regex.

The group names are used in back-reference \k<name> in pattern and ${name} in replacement string.

Named capturing groups are still numbered with the same numbering scheme, so they can also be accessed via Matcher.group(int group).

Internally, Java's implementation just maps from the name to the group number. Therefore, you cannot use the same name for 2 different capturing groups.

printf is great, but people forget about it.

$ for num in 1 10 100 1000 10000 100000 1000000; do printf "%10s %s\n" $num "foobar"; done
         1 foobar
        10 foobar
       100 foobar
      1000 foobar
     10000 foobar
    100000 foobar
   1000000 foobar

$ for((i=0;i<array_size;i++));
do
    printf "%10s %10d %10s" stringarray[$i] numberarray[$i] anotherfieldarray[%i]
done

Notice I used %10s for strings. %s is the important part. It tells it to use a string. The 10 in the middle says how many columns it is to be. %d is for numerics (digits).

man 1 printf for more info.

There's no true threading in JavaScript. JavaScript being the malleable language that it is, does allow you to emulate some of it. Here is an example I came across the other day.

The syntax for creating a new table is

CREATE TABLE new_table
AS
SELECT *
  FROM old_table

This will create a new table named new_table with whatever columns are in old_table and copy the data over. It will not replicate the constraints on the table, it won't replicate the storage attributes, and it won't replicate any triggers defined on the table.

SELECT INTO is used in PL/SQL when you want to fetch data from a table into a local variable in your PL/SQL block.

Try this:

• Edit the *.pubxml file in the PublishProfiles folder
• set DeleteExistingFiles true
• update all nugget packages, rebuild, republish and voila, issue resolved!

...worked for me when I had the same problem.

It's recommended to use a query parameter when the information is optional.

Route Parameters or Query Parameters?

There is no hard-and-fast rule. In general,

prefer a route parameter when

• the value is required.
• the value is necessary to distinguish one route path from another.

prefer a query parameter when

• the value is optional.
• the value is complex and/or multi-variate.

from https://angular.io/guide/router#optional-route-parameters

You just need to take out the parameter from the route path.

@RouteConfig([
{
    path: '/user/',
    component: User,
    as: 'User'
}])

>>> l = [list(range(i, i+4)) for i in range(10,1,-1)]
>>> l
[[10, 11, 12, 13], [9, 10, 11, 12], [8, 9, 10, 11], [7, 8, 9, 10], [6, 7, 8, 9], [5, 6, 7, 8], [4, 5, 6, 7], [3, 4, 5, 6], [2, 3, 4, 5]]
>>> sorted(l, key=sum)
[[2, 3, 4, 5], [3, 4, 5, 6], [4, 5, 6, 7], [5, 6, 7, 8], [6, 7, 8, 9], [7, 8, 9, 10], [8, 9, 10, 11], [9, 10, 11, 12], [10, 11, 12, 13]]

The above works. Are you doing something different?

Notice that your key function is just sum; there's no need to write it explicitly.

XmlTextWriter.WriteString() does the escaping.

I found that Bob Copeland solution http://bobcopeland.com/blog/2012/10/goto-in-bash/ elegant:

#!/bin/bash
# include this boilerplate
function jumpto
{
    label=$1
    cmd=$(sed -n "/$label:/{:a;n;p;ba};" $0 | grep -v ':$')
    eval "$cmd"
    exit
}

start=${1:-"start"}

jumpto $start

start:
# your script goes here...
x=100
jumpto foo

mid:
x=101
echo "This is not printed!"

foo:
x=${x:-10}
echo x is $x

results in:

$ ./test.sh
x is 100
$ ./test.sh foo
x is 10
$ ./test.sh mid
This is not printed!
x is 101

I had the same problem before and i fixed it by creating the same table in a new sheet and deleting all the name ranges associated to the table, i believe whene you're using listobjects you're not alowed to have name ranges contained within your table hope that helps thanks

Core-js did not work for me as it caused other issues, however, simply installing the latest version of npm i @types/es6-promise --save-dev got rid of the issues. The issues for me stemmed from compiling an sdk that was using rxjs. Here is the error I was getting:

`node_modules/rxjs/Observable.d.ts(59,60): error TS2693: Promise only refers to a type, but is being used as a value here.`

Inside the element put:

android:repeatCount="infinite"

Killing a process that owns port 3000

First, let’s take a look at how we can kill a process that has a port open.

Using the lsof command, we can retrieve the PID that has the given port:

$ lsof -i :3000 -t
12345

Then we can kill this process just by doing:

$ kill 12345

Let’s turn this into a one-liner:

lsof -i 3000 -t | xargs kill

If you’re using an environment variable to set the server port, we can specify that instead of hardcoding our values:

lsof -i ${PORT} -t | xargs kill

Lastly, we can default to port 3000 if the environment variable isn’t set:

lsof -i ${PORT:-3000} -t | xargs kill

Getting nodemon to execute hooks

Nodemon lets you set up event hooks through nodemon.json configuration file:

{
  "events": {
    "crash": "sh -c 'lsof -i :${PORT:-3000} -t | xargs kill'"
  }
}

This will cause nodemon to execute sh -c 'lsof -i :${PORT:-3000} -t | xargs kill command whenever your app crashes, thereby killing the child process it spawned that’s keeping the port open.

or you can try this one

fuser -k PORT-NO/tcp

eg:

fuser -k 3000/tcp

After installing Laminas, I got the same error message

"Translator component requires the intl PHP extension"

while wanting to view the web application with the php web server:

php -S 0.0.0.0:8080 -t public public/index.php

As I'm usgin XAMPP, in

c:\xampp\php\php.ini

I had to enable the PHP extension intl in this line ;extension=php_intl.dll, remove the starting semicolon (;) and restart XAMPP. I hope this will help.

I was looking for a single line code and found the following to work for my application. Here is what I did:

First Step: Install ImageMagick from the link below

https://www.imagemagick.org/script/download.php

Second Step: Point the cmd line to the folder where the images (in my case .png format) are placed

Third Step: Type the following command

magick -quality 100 *.png outvideo.mpeg

Thanks FogleBird for the idea!

There is an underlying buffer/stream that getchar() and friends read from. When you enter text, the text is stored in a buffer somewhere. getchar() can stream through it one character at a time. Each read returns the next character until it reaches the end of the buffer. The reason it's not asking you for subsequent characters is that it can fetch the next one from the buffer.

If you run your script and type directly into it, it will continue to prompt you for input until you press CTRL+D (end of file). If you call it like ./program < myInput where myInput is a text file with some data, it will get the EOF when it reaches the end of the input. EOF isn't a character that exists in the stream, but a sentinel value to indicate when the end of the input has been reached.

As an extra warning, I believe getchar() will also return EOF if it encounters an error, so you'll want to check ferror(). Example below (not tested, but you get the idea).

main() {
    int c;
    do {
        c = getchar();
        if (c == EOF && ferror()) {
            perror("getchar");
        }
        else {
            putchar(c);
        }
    }
    while(c != EOF);
}

Your function is failing because the groupby dataframe you end up with has a hierarchical index and two columns (Letter and N) so when you do .hist() it's trying to make a histogram of both columns hence the str error.

This is the default behavior of pandas plotting functions (one plot per column) so if you reshape your data frame so that each letter is a column you will get exactly what you want.

df.reset_index().pivot('index','Letter','N').hist()

The reset_index() is just to shove the current index into a column called index. Then pivot will take your data frame, collect all of the values N for each Letter and make them a column. The resulting data frame as 400 rows (fills missing values with NaN) and three columns (A, B, C). hist() will then produce one histogram per column and you get format the plots as needed.

This is the solution for Node.js which is asynchronous.

(JavaScript) Synchronizing forEach Loop with callbacks inside

It simply means that one chose the wrong encoding to read the file.

On Mac, use file -I file.txt to find the correct encoding. On Linux, use file -i file.txt.

I prefer to use two options, white spaces and empty:

test = test.Where(x => !string.IsNullOrEmpty(x)).ToArray();
test = test.Where(x => !string.IsNullOrWhiteSpace(x)).ToArray();

toEqual() compares values if Primitive or contents if Objects. toBe() compares references.

Following code / suite should be self explanatory :

describe('Understanding toBe vs toEqual', () => {
  let obj1, obj2, obj3;

  beforeEach(() => {
    obj1 = {
      a: 1,
      b: 'some string',
      c: true
    };

    obj2 = {
      a: 1,
      b: 'some string',
      c: true
    };

    obj3 = obj1;
  });

  afterEach(() => {
    obj1 = null;
    obj2 = null;
    obj3 = null;
  });

  it('Obj1 === Obj2', () => {
    expect(obj1).toEqual(obj2);
  });

  it('Obj1 === Obj3', () => {
    expect(obj1).toEqual(obj3);
  });

  it('Obj1 !=> Obj2', () => {
    expect(obj1).not.toBe(obj2);
  });

  it('Obj1 ==> Obj3', () => {
    expect(obj1).toBe(obj3);
  });
});

1. Use negative margins on the element you would like to minus pixels off. (desired element)
2. Make overflow:hidden; on the containing element
3. Switch to overflow:auto; on the desired element.

It worked for me!

For certain versions of Java, you can check the bitness of the JVM from the command line with the flags -d32 and -d64.

$ java -help
...
    -d32          use a 32-bit data model if available
    -d64          use a 64-bit data model if available

To check for a 64-bit JVM, run:

$ java -d64 -version

If it's not a 64-bit JVM, you'll get this:

Error: This Java instance does not support a 64-bit JVM.
Please install the desired version.

Similarly, to check for a 32-bit JVM, run:

$ java -d32 -version

If it's not a 32-bit JVM, you'll get this:

Error: This Java instance does not support a 32-bit JVM.
Please install the desired version.

These flags were added in Java 7, deprecated in Java 9, removed in Java 10, and no longer available on modern versions of Java.

int min = 65;
int max = 80;

Random r = new Random();
int i1 = r.nextInt(max - min + 1) + min;

Note that nextInt(int max) returns an int between 0 inclusive and max exclusive. Hence the +1.

The error is legitimate and may prevent your app from crashing. You typed makes as an array but it can also be undefined.

You have 2 options (instead of disabling the typescript's reason for existing...):

1. In your case the best is to type makes as possibily undefined.

makes?: any[]
// or
makes: any[] | undefined

In this case the compiler will inform you whenever you try to access to makes that it could be undefined. For exemple if the // <-- Not ok lines below are executed before getMakes finished or if getMakes fails, your app will crash and a runetime error will be thrown.

makes[0] // <-- Not ok
makes.map(...) // <-- Not ok

if (makes) makes[0] // <-- Ok
makes?.[0] // <-- Ok
(makes ?? []).map(...) // <-- Ok

2. You can assume that it will never fail and that you will never try to access it before initialization by writing the code below (risky!). So the compiler won't take care about it.

makes!: any[]

When you implement the action in the controller, use

return View("Index");

or

return RedirectToAction("Index");

where Index.cshtml (or the page that generates the action) page is already defined. Otherwise you are likely encountering "the view or its master was not found..." error.

Want to add an answer here for the sake of completeness.

<a href="tel:1234567">Call 123-4567</a>

Works just fine on most devices. However, on desktops this will appear as a link which does nothing when you click on it so you should consider using CSS to make it conditionally visible only on mobile devices.

Also, you should know that Skype (which is fairly popular) uses a different syntax by default (but can be parametered to use tel:).

<a href="callto:1234567">Call 123-4567</a>

However, I think in latest mobile browsers (I know for sure on Android) now the tel syntax should offer a popup of available applications that can be used to complete the calling action.

There's a easy way to paginate a table using breedjs (jQuery plugin), see the example:

HTML

<table>
  <thead>
    <tr>
      <th>Name</th>
      <th>Gender</th>
      <th>Age</th>
      <th>Email</th>
    </tr>
  </thead>
  <tbody>
    <tr b-scope="people" b-loop="person in people" b-paginate="5">
      <td>{{person.name}}</td>
      <td>{{person.gender}}</td>
      <td>{{person.age}}</td>
      <td>{{person.email}}</td>
    </tr>
  </tbody>
</table>
<ul></ul>

JS

var data={ people: [ {...}, {...}, ...] };

$(function() {
  breed.run({
    scope: 'people',
    input: data,
    runEnd: function(){ //This runEnd is just to mount the page buttons
        for(i=1 ; i<=breed.getPageCount('people') ; i++){
        $('ul').append(
            $('<li>',{
            html: i,
            onclick: "breed.paginate({scope: 'people', page: " + i + "});"
          })
        );
      }
    }
  });
});

Every time you want to change pages, just call:

breed.paginate({scope: 'people', page: pageNumber);

Working example.

With next variant I have no reaction:

dialog.requestWindowFeature(Window.FEATURE_NO_TITLE); //before     
dialog.setContentView(R.layout.logindialog);

So, I try to use next:

dialog.supportRequestWindowFeature(Window.FEATURE_NO_TITLE); //before     
dialog.setContentView(R.layout.logindialog);

This variant work excellent.

The constructor of PetStore will call a constructor of Farm; there's no way you can prevent it. If you do nothing (as you've done), it will call the default constructor (Farm()); if you need to pass arguments, you'll have to specify the base class in the initializer list:

PetStore::PetStore()
    : Farm( neededArgument )
    , idF( 0 )
{
}

(Similarly, the constructor of PetStore will call the constructor of nameF. The constructor of a class always calls the constructors of all of its base classes and all of its members.)

I experienced this exception, and it was also related to ServicePointManager.SecurityProtocol.

For me, this was because ServicePointManager.SecurityProtocol had been set to Tls | Tls11 (because of certain websites the application visits with broken TLS 1.2) and upon visiting a TLS 1.2-only website (tested with SSLLabs' SSL Report), it failed.

An option for .NET 4.5 and higher is to enable all TLS versions:

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls
                                     | SecurityProtocolType.Tls11
                                     | SecurityProtocolType.Tls12;

You can create dispatch queue using this code in swift 3.0

DispatchQueue.main.async
 {
   /*Write your code here*/
 }

   /* or */

let delayTime = DispatchTime.now() + Double(Int64(0.5 * Double(NSEC_PER_SEC))) / Double(NSEC_PER_SEC)                   
DispatchQueue.main.asyncAfter(deadline: delayTime)
{
  /*Write your code here*/
}

You need then a wrapping element with the bg image and in it the content element with the bg color:

<div id="Wrapper">
  <div id="Content">
    <!-- content here -->
  </div>
</div>

and the css:

#Wrapper{
    background:url(../img/bg/diagonalnoise.png); 
    width:300px; 
    height:300px;
}

#Content{
    background-color:rgba(248,247,216,0.7); 
    width:100%; 
    height:100%;
}

git diff HEAD origin/master

Where origin is the remote repository and master is the default branch where you will push. Also, do a git fetch before the diff so that you are not diffing against a stale origin/master.

P.S. I am also new to git, so in case the above is wrong, please rectify.

Long.valueOf(String s) - obviously due care must be taken to protect against non-numbers if that is possible in your code.

make can be parallelised easily (e.g., make -j 4). For example, here's a simple Makefile I'm using to download files in parallel using wget:

BASE=http://www.somewhere.com/path/to
FILES=$(shell awk '{printf "%s.ext\n", $$1}' filelist.txt)
LOG=download.log

all: $(FILES)
    echo $(FILES)

%.ext:
    wget -N -a $(LOG) $(BASE)/$@

.PHONY: all
default: all

Based on the answer of @macetw I print the exception directly to stderr in a decorator.

Python 3

from functools import wraps
from sys import stderr
from traceback import format_exc
from typing import Callable, Collection, Any, Mapping


def force_error_output(func: Callable):
    @wraps(func)
    def forced_error_output(*args: Collection[Any], **kwargs: Mapping[str, Any]):
        nonlocal func

        try:
            func(*args, **kwargs)
        except Exception as exception:
            stderr.write(format_exc())
            stderr.write("\n")
            stderr.flush()

            raise exception

    return forced_error_output

Python 2

from functools import wraps
from sys import stderr
from traceback import format_exc


def force_error_output(func):
    @wraps(func)
    def forced_error_output(*args, **kwargs):
        try:
            func(*args, **kwargs)
        except Exception as exception:
            stderr.write(format_exc())
            stderr.write("\n")
            stderr.flush()

            raise exception

    return forced_error_output

Then in your worker just use the decorator

@force_error_output
def da_worker(arg1: int, arg2: str):
    pass

Sorry for only commenting in the first place, but i'm posting almost every day a similar comment since many people think that it would be smart to encapsulate ADO.NET functionality into a DB-Class(me too 10 years ago). Mostly they decide to use static/shared objects since it seems to be faster than to create a new object for any action.

That is neither a good idea in terms of peformance nor in terms of fail-safety.

Don't poach on the Connection-Pool's territory

There's a good reason why ADO.NET internally manages the underlying Connections to the DBMS in the ADO-NET Connection-Pool:

In practice, most applications use only one or a few different configurations for connections. This means that during application execution, many identical connections will be repeatedly opened and closed. To minimize the cost of opening connections, ADO.NET uses an optimization technique called connection pooling.

Connection pooling reduces the number of times that new connections must be opened. The pooler maintains ownership of the physical connection. It manages connections by keeping alive a set of active connections for each given connection configuration. Whenever a user calls Open on a connection, the pooler looks for an available connection in the pool. If a pooled connection is available, it returns it to the caller instead of opening a new connection. When the application calls Close on the connection, the pooler returns it to the pooled set of active connections instead of closing it. Once the connection is returned to the pool, it is ready to be reused on the next Open call.

So obviously there's no reason to avoid creating,opening or closing connections since actually they aren't created,opened and closed at all. This is "only" a flag for the connection pool to know when a connection can be reused or not. But it's a very important flag, because if a connection is "in use"(the connection pool assumes), a new physical connection must be openend to the DBMS what is very expensive.

So you're gaining no performance improvement but the opposite. If the maximum pool size specified (100 is the default) is reached, you would even get exceptions(too many open connections ...). So this will not only impact the performance tremendously but also be a source for nasty errors and (without using Transactions) a data-dumping-area.

If you're even using static connections you're creating a lock for every thread trying to access this object. ASP.NET is a multithreading environment by nature. So theres a great chance for these locks which causes performance issues at best. Actually sooner or later you'll get many different exceptions(like your ExecuteReader requires an open and available Connection).

Conclusion:

• Don't reuse connections or any ADO.NET objects at all.
• Don't make them static/shared(in VB.NET)
• Always create, open(in case of Connections), use, close and dispose them where you need them(f.e. in a method)
• use the using-statement to dispose and close(in case of Connections) implicitely

That's true not only for Connections(although most noticable). Every object implementing IDisposable should be disposed(simplest by using-statement), all the more in the System.Data.SqlClient namespace.

All the above speaks against a custom DB-Class which encapsulates and reuse all objects. That's the reason why i commented to trash it. That's only a problem source.

Edit: Here's a possible implementation of your retrievePromotion-method:

public Promotion retrievePromotion(int promotionID)
{
    Promotion promo = null;
    var connectionString = System.Configuration.ConfigurationManager.ConnectionStrings["MainConnStr"].ConnectionString;
    using (SqlConnection connection = new SqlConnection(connectionString))
    {
        var queryString = "SELECT PromotionID, PromotionTitle, PromotionURL FROM Promotion WHERE PromotionID=@PromotionID";
        using (var da = new SqlDataAdapter(queryString, connection))
        {
            // you could also use a SqlDataReader instead
            // note that a DataTable does not need to be disposed since it does not implement IDisposable
            var tblPromotion = new DataTable();
            // avoid SQL-Injection
            da.SelectCommand.Parameters.Add("@PromotionID", SqlDbType.Int);
            da.SelectCommand.Parameters["@PromotionID"].Value = promotionID;
            try
            {
                connection.Open(); // not necessarily needed in this case because DataAdapter.Fill does it otherwise 
                da.Fill(tblPromotion);
                if (tblPromotion.Rows.Count != 0)
                {
                    var promoRow = tblPromotion.Rows[0];
                    promo = new Promotion()
                    {
                        promotionID    = promotionID,
                        promotionTitle = promoRow.Field<String>("PromotionTitle"),
                        promotionUrl   = promoRow.Field<String>("PromotionURL")
                    };
                }
            }
            catch (Exception ex)
            {
                // log this exception or throw it up the StackTrace
                // we do not need a finally-block to close the connection since it will be closed implicitely in an using-statement
                throw;
            }
        }
    }
    return promo;
}

I'm currently taking some legacy codebases and introducing minimal TypeScript changes to see if it helps our team. Depending on how strict you want to be with TypeScript, this may or may not be an option for you.

The most helpful way for us to get started was to extend our tsconfig.json file with this property:

// tsconfig.json excerpt:

{
  ...
  "compilerOptions": {
    ...
    "allowJs": true,
    ...
  }
  ...
}

This change lets our JS files that have JSDoc type hints get compiled. Also our IDEs (JetBrains IDEs and VS Code) can provide code-completion and Intellisense.

Just as an idea of a different style of string manipulation in C, here's an example which does not modify the source string, and does not use malloc. To find spaces I use the libc function strpbrk.

int print_words(const char *string, FILE *f)
{
   static const char space_characters[] = " \t";
   const char *next_space;

   // Find the next space in the string
   //
   while ((next_space = strpbrk(string, space_characters)))
   {
      const char *p;

      // If there are non-space characters between what we found
      // and what we started from, print them.
      //
      if (next_space != string)
      {
         for (p=string; p<next_space; p++)
         {
            if(fputc(*p, f) == EOF)
            {
               return -1;
            }

I think you can get it using subc1.text.

>>> html = """
<p>
    <strong class="offender">YOB:</strong> 1987<br />
    <strong class="offender">RACE:</strong> WHITE<br />
    <strong class="offender">GENDER:</strong> FEMALE<br />
    <strong class="offender">HEIGHT:</strong> 5'05''<br />
    <strong class="offender">WEIGHT:</strong> 118<br />
    <strong class="offender">EYE COLOR:</strong> GREEN<br />
    <strong class="offender">HAIR COLOR:</strong> BROWN<br />
</p>
"""
>>> from bs4 import BeautifulSoup
>>> soup = BeautifulSoup(html)
>>> print soup.text


YOB: 1987
RACE: WHITE
GENDER: FEMALE
HEIGHT: 5'05''
WEIGHT: 118
EYE COLOR: GREEN
HAIR COLOR: BROWN

Or if you want to explore it, you can use .contents :

>>> p = soup.find('p')
>>> from pprint import pprint
>>> pprint(p.contents)
[u'\n',
 <strong class="offender">YOB:</strong>,
 u' 1987',
 <br/>,
 u'\n',
 <strong class="offender">RACE:</strong>,
 u' WHITE',
 <br/>,
 u'\n',
 <strong class="offender">GENDER:</strong>,
 u' FEMALE',
 <br/>,
 u'\n',
 <strong class="offender">HEIGHT:</strong>,
 u" 5'05''",
 <br/>,
 u'\n',
 <strong class="offender">WEIGHT:</strong>,
 u' 118',
 <br/>,
 u'\n',
 <strong class="offender">EYE COLOR:</strong>,
 u' GREEN',
 <br/>,
 u'\n',
 <strong class="offender">HAIR COLOR:</strong>,
 u' BROWN',
 <br/>,
 u'\n']

and filter out the necessary items from the list:

>>> data = dict(zip([x.text for x in p.contents[1::4]], [x.strip() for x in p.contents[2::4]]))
>>> pprint(data)
{u'EYE COLOR:': u'GREEN',
 u'GENDER:': u'FEMALE',
 u'HAIR COLOR:': u'BROWN',
 u'HEIGHT:': u"5'05''",
 u'RACE:': u'WHITE',
 u'WEIGHT:': u'118',
 u'YOB:': u'1987'}

I think you need some sort of regular expression matching (the following code is in Python 3):

import string
import re
import nltk

s = "I can't do this now, because I'm so tired.  Please give me some time."
l = nltk.word_tokenize(s)
ll = [x for x in l if not re.fullmatch('[' + string.punctuation + ']+', x)]
print(l)
print(ll)

Output:

['I', 'ca', "n't", 'do', 'this', 'now', ',', 'because', 'I', "'m", 'so', 'tired', '.', 'Please', 'give', 'me', 'some', 'time', '.']
['I', 'ca', "n't", 'do', 'this', 'now', 'because', 'I', "'m", 'so', 'tired', 'Please', 'give', 'me', 'some', 'time']

Should work well in most cases since it removes punctuation while preserving tokens like "n't", which can't be obtained from regex tokenizers such as wordpunct_tokenize.

For IBM DB2 :

SELECT TYPENAME FROM SYSCAT.COLUMNS WHERE TABSCHEMA='your_schema_name' AND TABNAME='your_table_name' AND COLNAME='your_column_name'

use this in your drawable

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" 
    android:shape="oval">


    <solid android:color="#55ff55"/>


    <size android:height="60dp"
        android:width="60dp"/>

</shape>

Set background for the textview as this

If you want to also select extra fields:

Model.select('DISTINCT ON (models.ratings) models.ratings, models.id').map { |m| [m.id, m.ratings] }

I ran into the same exact problem around noon today and finally found a solution here --> Trying to resize2fs EB volume fails

I skipped mounting, since the partition was already mounted.

Apparently CentOS 7 uses XFS as the default file system and as a result resize2fs will fail.

I took a look in /etc/fstab, and guess what, XFS was staring me in the face... Hope this helps.

Make sure that the -L option appears ahead of the -l option; the order of options in linker command lines does matter, especially with static libraries. The -L option specifies a directory to be searched for libraries (static or shared). The -lname option specifies a library which is with libmine.a (static) or libmine.so (shared on most variants of Unix, but Mac OS X uses .dylib and HP-UX used to use .sl). Conventionally, a static library will be in a file libmine.a. This is convention, not mandatory, but if the name is not in the libmine.a format, you cannot use the -lmine notation to find it; you must list it explicitly on the compiler (linker) command line.

The -L./libmine option says "there is a sub-directory called libmine which can be searched to find libraries". I can see three possibilities:

1. You have such a sub-directory containing libmine.a, in which case you also need to add -lmine to the linker line (after the object files that reference the library).
2. You have a file libmine that is a static archive, in which case you simply list it as a file ./libmine with no -L in front.
3. You have a file libmine.a in the current directory that you want to pick up. You can either write ./libmine.a or -L . -lmine and both should find the library.

When you set 64-bit the resulting binary is a "Fat" binary, which contains all three Mach-O images bundled with a thin fat header. You can see that using otool or jtool. You can check out some fat binaries included as part of the iOS 7.0 SDK, for example the AVFoundation Framework, like so:

% cd  /Developer/Platforms/iPhoneOS.platform/DeviceSupport/7.0\ \(11A465\)/Symbols/System/Library/Frameworks/AVFoundation.framework/

%otool -V -f AVFoundation                                                                     9:36

As for the binary itself, it uses the ARM64 bit instruction set, which is (mostly compatible with 32-bit, but) a totally different instruction set. This is especially important for graphics program (using NEON instructions and registers). Likewise, the CPU has more registers, which makes quite an impact on program speed. There's an interesting discussion in http://blogs.barrons.com/techtraderdaily/2013/09/19/apple-the-64-bit-question/?mod=yahoobarrons on whether or not this makes a difference; benchmarking tests have so far clearly indicated that it does.

Using otool -tV will dump the assembly (if you have XCode 5 and later), and then you can see the instruction set differences for yourself. Most (but not all) developers will remain agnostic to the changes, as for the most part they do not directly affect Obj-C (CG* APIs notwithstanding), and have to do more with low level pointer handling. The compiler will work its magic and optimizations.

Use multiple datasource or realizing the separation of reading & writing. you must have a knowledge of Class AbstractRoutingDataSource which support dynamic datasource choose.

Here is my datasource.yaml and I figure out how to resolve this case. You can refer to this project spring-boot + quartz. Hope this will help you.

You can do it using old DirectShow functionality.

This answer teaches you how to create QuartzTypeLib.dll:

1. Run tlbimp tool (in your case path will be different):

2. Run TlbImp.exe %windir%\system32\quartz.dll /out:QuartzTypeLib.dll

Alternatively, this project contains the library interop.QuartzTypeLib.dll, which is basically the same thing as steps 1. and 2. The following steps teach how to use this library:

3. Add generated QuartzTypeLib.dll as a COM-reference to your project (click right mouse button on the project name in "Solution Explorer", then select "Add" menu item and then "Reference")

4. In your Project, expand the "References", find the QuartzTypeLib reference. Right click it and select properties, and change "Embed Interop Types" to false. (Otherwise you won't be able to use the FilgraphManager class in your project (and probably a couple of other ones)).

5. In Project Settings, in the Build tab, I had to disable the Prefer 32-bit flag, Otherwise I would get this Exception: System.Runtime.InteropServices.COMException: Exception from HRESULT: 0x80040266

6. Use this class to play your favorite MP3 file:

   using QuartzTypeLib;
   
   public sealed class DirectShowPlayer
   {
       private FilgraphManager FilterGraph;
   
       public void Play(string path)
       {
           FilgraphManager = new FilgraphManager();
           FilterGraph.RenderFile(path);
           FilterGraph.Run();
       }
   
       public void Stop()
       {
           FilterGraph?.Stop();
       }
   }
   

PS: TlbImp.exe can be found here: "C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin", or in "C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.7.2 Tools"

Here is some interesting information about SET / SELECT

• SET is the ANSI standard for variable assignment, SELECT is not.
• SET can only assign one variable at a time, SELECT can make multiple assignments at once.
• If assigning from a query, SET can only assign a scalar value. If the query returns multiple values/rows then SET will raise an error. SELECT will assign one of the values to the variable and hide the fact that multiple values were returned (so you'd likely never know why something was going wrong elsewhere - have fun troubleshooting that one)
• When assigning from a query if there is no value returned then SET will assign NULL, where SELECT will not make the assignment at all (so the variable will not be changed from it's previous value)
• As far as speed differences - there are no direct differences between SET and SELECT. However SELECT's ability to make multiple assignments in one shot does give it a slight speed advantage over SET.

Having a single exit point reduces Cyclomatic Complexity and therefore, in theory, reduces the probability that you will introduce bugs into your code when you change it. Practice however, tends to suggest that a more pragmatic approach is needed. I therefore tend to aim to have a single exit point, but allow my code to have several if that is more readable.

The same as Brian, but add to this answer from tstempko:

https://sqa.stackexchange.com/questions/3481/quicker-way-to-assert-that-an-element-does-not-exist

So I tried and it works quickly:

driver.implicitly_wait(0)

if driver.find_element_by_id("show_reflist"):        
 driver.find_element_by_id("show_reflist").find_element_by_tag_name("img").click()

after this I restore my default value

driver.implicitly_wait(30)

In fact, this is a "how to" subject. So, here is the reference implementation:

    public class BOX
    {
        double height, length, breadth;

        public static bool operator == (BOX b1, BOX b2)
        {
            if ((object)b1 == null)
                return (object)b2 == null;

            return b1.Equals(b2);
        }

        public static bool operator != (BOX b1, BOX b2)
        {
            return !(b1 == b2);
        }

        public override bool Equals(object obj)
        {
            if (obj == null || GetType() != obj.GetType())
                return false;

            var b2 = (BOX)obj;
            return (length == b2.length && breadth == b2.breadth && height == b2.height);
        }

        public override int GetHashCode()
        {
            return height.GetHashCode() ^ length.GetHashCode() ^ breadth.GetHashCode();
        }
    }

UPDATE: the cast to (object) in the operator == implementation is important, otherwise, it would re-execute the operator == overload, leading to a stackoverflow. Credits to @grek40.

This (object) cast trick is from Microsoft String == implementaiton. SRC: https://github.com/Microsoft/referencesource/blob/master/mscorlib/system/string.cs#L643

This behaviour is terminal-specific and specified by the terminal emulator you use (e.g. xterm) and the semantics of terminal that it provides. The terminal behaviour has been very stable for the last 20 years, and you can reasonably rely on the semantics of \b.

I had the same issue , I am using eclipse, just in case others experience the same issue:
In eclipse double click the tomcat server,
stop the server
untick the "server modules without publishing"
start the server.

adding to the top answer: here is some sample code from PHP and Jquery:

$("#button").click(function () {
 $.ajax({
            type: "POST",
            url: "handler.php",
            data: dataString,

                success: function(data) {

                  if(data.status == "success"){

                 /* alert("Thank you for subscribing!");*/

                   $(".title").html("");
                    $(".message").html(data.message)
                    .hide().fadeIn(1000, function() {
                        $(".message").append("");
                        }).delay(1000).fadeOut("fast");

                 /*    setTimeout(function() {
                      window.location.href = "myhome.php";
                    }, 2500);*/


                  }
                  else if(data.status == "error"){
                      alert("Error on query!");
                  }




                    }


        });

        return false;
     }
 });

PHP - send custom message / status:

    $response_array['status'] = 'success'; /* match error string in jquery if/else */ 
    $response_array['message'] = 'RFQ Sent!';   /* add custom message */ 
    header('Content-type: application/json');
    echo json_encode($response_array);

I've found this absolutely invaluable when unable to grab something in a custom class or changing id's:

driver.find_element_by_xpath("//*[contains(text(), 'Show Next Date Available')]").click()
driver.find_element_by_xpath("//*[contains(text(), 'Show Next Date Available')]").text
driver.find_element_by_xpath("//*[contains(text(), 'Available')]").text
driver.find_element_by_xpath("//*[contains(text(), 'Avail')]").text

str is text representation in bytes, unicode is text representation in characters.

You decode text from bytes to unicode and encode a unicode into bytes with some encoding.

That is:

>>> 'abc'.decode('utf-8')  # str to unicode
u'abc'
>>> u'abc'.encode('utf-8') # unicode to str
'abc'

UPD Sep 2020: The answer was written when Python 2 was mostly used. In Python 3, str was renamed to bytes, and unicode was renamed to str.

>>> b'abc'.decode('utf-8') # bytes to str
'abc'
>>> 'abc'.encode('utf-8'). # str to bytes
b'abc'

First make sure you have checked the most voted answer.

I'm not sure if it's exactly your problem, but in my case, I wasn't able to upgrade Django to 1.2.4 - I was always finishing with 1.2.3 version, so I uninstalled Django with:

<virtualenv>/bin/pip uninstall Django

Then I removed <virtualenv>/build/Django directory and finally I installed the proper version with:

<virtualenv>/bin/pip install Django

Use Underscore.js

It cross-browser compliant and can perform a binary search if your data is sorted.

_.indexOf

_.indexOf(array, value, [isSorted]) Returns the index at which value can be found in the array, or -1 if value is not present in the array. Uses the native indexOf function unless it's missing. If you're working with a large array, and you know that the array is already sorted, pass true for isSorted to use a faster binary search.

Example

//Tell underscore your data is sorted (Binary Search)
if(_.indexOf(['2','3','4','5','6'], '4', true) != -1){
    alert('true');
}else{
    alert('false');   
}

//Unsorted data works to!
if(_.indexOf([2,3,6,9,5], 9) != -1){
    alert('true');
}else{
    alert('false');   
}

You can try one even more simple:

<option value="1" ${item.quantity == 1 ? "selected" : ""}>1</option>

Quick and dirty:

#!/usr/bin/perl -w

use strict;

open(FILE, "</tmp/yourfile.txt") || die "File not found";
my @lines = <FILE>;
close(FILE);

foreach(@lines) {
   $_ =~ s/<PREF>/ABCD/g;
}

open(FILE, ">/tmp/yourfile.txt") || die "File not found";
print FILE @lines;
close(FILE);

Perhaps it i a good idea not to write the result back to your original file; instead write it to a copy and check the result first.

This always works for me:

import android.app.Activity;
import android.content.Context;

public class yourClass {

 Context ctx;

 public yourClass (Handler handler, Context context) {
 super(handler);
    ctx = context;
 }

 //Use context (ctx) in your code like this:
 block1 = new Droid(BitmapFactory.decodeResource(ctx.getResources(), R.drawable.birdpic), 100, 10);
 //OR
 builder.setLargeIcon(BitmapFactory.decodeResource(ctx.getResources(), R.drawable.birdpic));
 //OR
 final Intent intent = new Intent(ctx, MainActivity.class);
 //OR
 NotificationManager notificationManager = (NotificationManager) ctx.getSystemService(Context.NOTIFICATION_SERVICE);
 //ETC...

}

Not related to this question but example using a Fragment to access system resources/activity like this:

public boolean onQueryTextChange(String newText) {
 Activity activity = getActivity();
 Context context = activity.getApplicationContext();
 returnSomething(newText);
 return false;
}

View customerInfo = getActivity().getLayoutInflater().inflate(R.layout.main_layout_items, itemsLayout, false);
 itemsLayout.addView(customerInfo);

It allows servlets to have multiple servlet mappings:

<servlet>
    <servlet-name>Servlet1</servlet-name>
    <servlet-path>foo.Servlet</servlet-path>
</servlet>
<servlet-mapping>
    <servlet-name>Servlet1</servlet-name>
    <url-pattern>/enroll</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>Servlet1</servlet-name>
    <url-pattern>/pay</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>Servlet1</servlet-name>
    <url-pattern>/bill</url-pattern>
</servlet-mapping>

It allows filters to be mapped on the particular servlet:

<filter-mapping>
    <filter-name>Filter1</filter-name>
    <servlet-name>Servlet1</servlet-name>
</filter-mapping>

Your proposal would support neither of them. Note that the web.xml is read and parsed only once during application's startup, not on every HTTP request as you seem to think.

Since Servlet 3.0, there's the @WebServlet annotation which minimizes this boilerplate:

@WebServlet("/enroll")
public class Servlet1 extends HttpServlet {

I tried several approaches.

# BY {dplyr}
data.table(ID      = c(rep("A", 5), rep("B",5)), 
           Quarter = c(1:5, 1:5), 
           value   = rnorm(10)) -> df1
df1 %<>% dplyr::mutate(ID      = as.factor(ID),
                       Quarter = as.character(Quarter))
# check classes
dplyr::glimpse(df1)
# Observations: 10
# Variables: 3
# $ ID      (fctr) A, A, A, A, A, B, B, B, B, B
# $ Quarter (chr) "1", "2", "3", "4", "5", "1", "2", "3", "4", "5"
# $ value   (dbl) -0.07676732, 0.25376110, 2.47192852, 0.84929175, -0.13567312,  -0.94224435, 0.80213218, -0.89652819...

, or otherwise

# from list to data.table using data.table::setDT
list(ID      = as.factor(c(rep("A", 5), rep("B",5))), 
     Quarter = as.character(c(1:5, 1:5)), 
     value   = rnorm(10)) %>% setDT(list.df) -> df2
class(df2)
# [1] "data.table" "data.frame"

In fact, unsigned int on most modern processors (ARM, Intel/AMD, Alpha, SPARC, Itanium ,PowerPC) will have a range of 0 to 2^32 - 1 which is 4,294,967,295 = 0xffffffff because int (both signed and unsigned) will be 32 bits long and the largest one is as stated.

(unsigned short will have maximal value 2^16 - 1 = 65,535 )

(unsigned) long long int will have a length of 64 bits (long int will be enough under most 64 bit Linuxes, etc, but the standard promises 64 bits for long long int). Hence these have the range 0 to 2^64 - 1 = 18446744073709551615

Don't want to be repetitive, but just to summarize in other way (features added in new HttpClient):

• Automatic conversion from JSON to an object
• Response type definition
• Event firing
• Simplified syntax for headers
• Interceptors

I wrote an article, where I covered the difference between old "http" and new "HttpClient". The goal was to explain it in the easiest way possible.

Simply about new HttpClient in Angular

Well I did not read correctly the man echo page for this.

echo had 2 options that could do this if I added a 3rd escape character.

The 2 options are -n and -e.

-n will not output the trailing newline. So that saves me from going to a new line each time I echo something.

-e will allow me to interpret backslash escape symbols.

Guess what escape symbol I want to use for this: \r. Yes, carriage return would send me back to the start and it will visually look like I am updating on the same line.

So the echo line would look like this:

echo -ne "Movie $movies - $dir ADDED!"\\r

I had to escape the escape symbol so Bash would not kill it. that is why you see 2 \ symbols in there.

As mentioned by William, printf can also do similar (and even more extensive) tasks like this.

You can just read from a file, jsonifying each line as you go:

tweets = []
for line in open('tweets.json', 'r'):
    tweets.append(json.loads(line))

This avoids storing intermediate python objects. As long as your write one full tweet per append() call, this should work.

Using BalusC's suggestion of implementing Collection i can now hide my primefaces p:dataTable using not empty operator on my dataModel that extends javax.faces.model.ListDataModel

Code sample:

import java.io.Serializable;
import java.util.Collection;
import java.util.List;
import javax.faces.model.ListDataModel;
import org.primefaces.model.SelectableDataModel;

public class EntityDataModel extends ListDataModel<Entity> implements
        Collection<Entity>, SelectableDataModel<Entity>, Serializable {

    public EntityDataModel(List<Entity> data) { super(data); }

    @Override
    public Entity getRowData(String rowKey) {
        // In a real app, a more efficient way like a query by rowKey should be
        // implemented to deal with huge data
        List<Entity> entitys = (List<Entity>) getWrappedData();
        for (Entity entity : entitys) {
            if (Integer.toString(entity.getId()).equals(rowKey)) return entity;
        }
        return null;
    }

    @Override
    public Object getRowKey(Entity entity) {
        return entity.getId();
    }

    @Override
    public boolean isEmpty() {
        List<Entity> entity = (List<Entity>) getWrappedData();
        return (entity == null) || entity.isEmpty();
    }
    // ... other not implemented methods of Collection...
}

Django's Model class specifically handles having an attribute named Meta which is a class. It's not a general Python thing.

Python metaclasses are completely different.

In Ef .net core there are two options that you can do; first with data annotations:

public class Blog
{
    public int BlogId { get; set; }
    [Required]
    public string Url { get; set; }
}

Or with fluent api:

class MyContext : DbContext
{
    public DbSet<Blog> Blogs { get; set; }

    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        modelBuilder.Entity<Blog>()
            .Property(b => b.Url)
            .IsRequired(false)//optinal case
            .IsRequired()//required case
            ;
    }
}

public class Blog
{
    public int BlogId { get; set; }
    public string Url { get; set; }
}

Consider the below figure and program to understand this concept better.

As per the figure, ptr1 is a single pointer which is having address of variable num.

ptr1 = #

Similarly ptr2 is a pointer to pointer(double pointer) which is having the address of pointer ptr1.

ptr2 = &ptr1;

A pointer which points to another pointer is known as double pointer. In this example ptr2 is a double pointer.

Values from above diagram :

Address of variable num has : 1000
Address of Pointer ptr1 is: 2000
Address of Pointer ptr2 is: 3000

Example:

#include <stdio.h>

int main ()
{
   int  num = 10;
   int  *ptr1;
   int  **ptr2;

   // Take the address of var 
   ptr1 = &num;

   // Take the address of ptr1 using address of operator &
   ptr2 = &ptr1;

   // Print the value
   printf("Value of num = %d\n", num );
   printf("Value available at *ptr1 = %d\n", *ptr1 );
   printf("Value available at **ptr2 = %d\n", **ptr2);
}

Output:

Value of num = 10
Value available at *ptr1 = 10
Value available at **ptr2 = 10

The document.domain method

• Method type: iframe.

Note that this is an iframe method that sets the value of document.domain to a suffix of the current domain. If it does so, the shorter domain is used for subsequent origin checks. For example, assume a script in the document at http://store.company.com/dir/other.html executes the following statement:

document.domain = "company.com";

After that statement executes, the page would pass the origin check with http://company.com/dir/page.html. However, by the same reasoning, company.com could not set document.domain to othercompany.com.

With this method, you would be allowed to exectue javascript from an iframe sourced on a subdomain on a page sourced on the main domain. This method is not suited for cross-domain resources as browsers like Firefox will not allow you to change the document.domain to a completely alien domain.

The Cross-Origin Resource Sharing method

• Method type: AJAX.

Cross-Origin Resource Sharing (CORS) is a W3C Working Draft that defines how the browser and server must communicate when accessing sources across origins. The basic idea behind CORS is to use custom HTTP headers to allow both the browser and the server to know enough about each other to determine if the request or response should succeed or fail.

For a simple request, one that uses either GET or POST with no custom headers and whose body is text/plain, the request is sent with an extra header called Origin. The Origin header contains the origin (protocol, domain name, and port) of the requesting page so that the server can easily determine whether or not it should serve a response. An example Origin header might look like this:

Origin: http://www.stackoverflow.com

If the server decides that the request should be allowed, it sends a Access-Control-Allow-Origin header echoing back the same origin that was sent or * if it’s a public resource. For example:

Access-Control-Allow-Origin: http://www.stackoverflow.com

If this header is missing, or the origins don’t match, then the browser disallows the request. If all is well, then the browser processes the request. Note that neither the requests nor responses include cookie information.

The Mozilla team suggests in their post about CORS that you should check for the existence of the withCredentials property to determine if the browser supports CORS via XHR. You can then couple with the existence of the XDomainRequest object to cover all browsers:

function createCORSRequest(method, url){
    var xhr = new XMLHttpRequest();
    if ("withCredentials" in xhr){
        xhr.open(method, url, true);
    } else if (typeof XDomainRequest != "undefined"){
        xhr = new XDomainRequest();
        xhr.open(method, url);
    } else {
        xhr = null;
    }
    return xhr;
}

var request = createCORSRequest("get", "http://www.stackoverflow.com/");
if (request){
    request.onload = function() {
        // ...
    };
    request.onreadystatechange = handler;
    request.send();
}

Note that for the CORS method to work, you need to have access to any type of server header mechanic and can't simply access any third-party resource.

The window.postMessage method

• Method type: iframe.

window.postMessage, when called, causes a MessageEvent to be dispatched at the target window when any pending script that must be executed completes (e.g. remaining event handlers if window.postMessage is called from an event handler, previously-set pending timeouts, etc.). The MessageEvent has the type message, a data property which is set to the string value of the first argument provided to window.postMessage, an origin property corresponding to the origin of the main document in the window calling window.postMessage at the time window.postMessage was called, and a source property which is the window from which window.postMessage is called.

To use window.postMessage, an event listener must be attached:

    // Internet Explorer
    window.attachEvent('onmessage',receiveMessage);

    // Opera/Mozilla/Webkit
    window.addEventListener("message", receiveMessage, false);

And a receiveMessage function must be declared:

function receiveMessage(event)
{
    // do something with event.data;
}

The off-site iframe must also send events properly via postMessage:

<script>window.parent.postMessage('foo','*')</script>

Any window may access this method on any other window, at any time, regardless of the location of the document in the window, to send it a message. Consequently, any event listener used to receive messages must first check the identity of the sender of the message, using the origin and possibly source properties. This cannot be understated: Failure to check the origin and possibly source properties enables cross-site scripting attacks.

This has always worked well for me:

yAxes: [{
         ticks: {
                 display: false;
                },

Short and sweet :). what I believe in.

int PERMISSION_ALL = 1;
String[] PERMISSIONS = {Manifest.permission.CAMERA, Manifest.permission.WRITE_EXTERNAL_STORAGE}; // List of permissions required

public void askPermission()
{
    for (String permission : PERMISSIONS) {
        if (ActivityCompat.checkSelfPermission(this, permission) != PackageManager.PERMISSION_GRANTED) {
            requestPermissions(PERMISSIONS, PERMISSION_ALL);
            return;
        }
    }
}

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions,
                                       int[] grantResults) {

    switch (requestCode) {
        case 1:{
            if(grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED && grantResults[1] == PackageManager.PERMISSION_GRANTED){
                //Do your work.
            } else {
                Toast.makeText(this, "Until you grant the permission, we cannot proceed further", Toast.LENGTH_SHORT).show();
            }
            return;
        }
    }

If the setTimeout function does not work for you either, then do the following:

//Create an iframe
iframe = $('body').append($('<iframe id="documentToPrint" name="documentToPrint" src="about:blank"/>'));
iframeElement = $('#documentToPrint')[0].contentWindow.document;

//Open the iframe
iframeElement.open();

//Write your content to the iframe
iframeElement.write($("yourContentId").html());

//This is the important bit.
//Wait for the iframe window to load, then print it.
$('#documentToPrint')[0].contentWindow.onload = function () {
    $('#print-document')[0].contentWindow.print();
    $('#print-document').remove();
};
iframeElement.close();

java.time

In Java 8 there is no need to use Joda-Time as it comes with a similar new API in the java.time package. Use the LocalDate class.

LocalDate date = LocalDate.of(2014, 3, 18);
LocalDate today = LocalDate.now();

Boolean isToday = date.isEqual( today );

You can ask for the span of time between the dates with Period class.

Period difference = Period.between(date, today);

LocalDate is comparable using equals and compareTo as it holds no information about Time and Timezone.

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android, the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

Try this:

urllib.pathname2url(stringToURLEncode)

urlencode won't work because it only works on dictionaries. quote_plus didn't produce the correct output.

If your API level is 19+ you can use translation as above. If your API level is less than 19, you can take a look at similar tutorial: http://trickyandroid.com/fragments-translate-animation/

Solution is to change Delimiter.

Content of the csv file -> Note .. Also space and , in value

Values are 6 Dutch word aap,noot,mies,Piet, Gijs, Jan

Col1;Col2;Col3

a,ap;noo,t;mi es

P,iet;G ,ijs;Ja ,n



$csv = Import-Csv C:\TejaCopy.csv -Delimiter ';' 

Answer:

Write-Host $csv
@{Col1=a,ap; Col2=noo,t; Col3=mi es} @{Col1=P,iet; Col2=G ,ijs; Col3=Ja ,n}

It is possible to read a CSV file and use other Delimiter to separate each column.

It worked for my script :-)

The list.append function does not return any value(but None), it just adds the value to the list you are using to call that method.

In the first loop round you will assign None (because the no-return of append) to a, then in the second round it will try to call a.append, as a is None it will raise the Exception you are seeing

You just need to change it to:

a=[]
for i in range(5):    
    a.append(i)
print(a)
# [0, 1, 2, 3, 4]

list.append is what is called a mutating or destructive method, i.e. it will destroy or mutate the previous object into a new one(or a new state).

If you would like to create a new list based in one list without destroying or mutating it you can do something like this:

a=['a', 'b', 'c']
result = a + ['d']

print result
# ['a', 'b', 'c', 'd']

print a
# ['a', 'b', 'c']

As a corollary only, you can mimic the append method by doing the following:

a=['a', 'b', 'c']
a = a + ['d']

print a
# ['a', 'b', 'c', 'd']

In a comment on @paxdiablo's answer, you asked:

"So basically, is it better to use Double than Float?"

That is a complicated question. I will deal with it in two parts

Deciding between double versus float

On the one hand, a double occupies 8 bytes versus 4 bytes for a float. If you have many of them, this may be significant, though it may also have no impact. (Consider the case where the values are in fields or local variables on a 64bit machine, and the JVM aligns them on 64 bit boundaries.) Additionally, floating point arithmetic with double values is typically slower than with float values ... though once again this is hardware dependent.

On the other hand, a double can represent larger (and smaller) numbers than a float and can represent them with more than twice the precision. For the details, refer to Wikipedia.

The tricky question is knowing whether you actually need the extra range and precision of a double. In some cases it is obvious that you need it. In others it is not so obvious. For instance if you are doing calculations such as inverting a matrix or calculating a standard deviation, the extra precision may be critical. On the other hand, in some cases not even double is going to give you enough precision. (And beware of the trap of expecting float and double to give you an exact representation. They won't and they can't!)

There is a branch of mathematics called Numerical Analysis that deals with the effects of rounding error, etc in practical numerical calculations. It used to be a standard part of computer science courses ... back in the 1970's.

Deciding between Double versus Float

For the Double versus Float case, the issues of precision and range are the same as for double versus float, but the relative performance measures will be slightly different.

• A Double (on a 32 bit machine) typically takes 16 bytes + 4 bytes for the reference, compared with 12 + 4 bytes for a Float. Compare this to 8 bytes versus 4 bytes for the double versus float case. So the ratio is 5 to 4 versus 2 to 1.

• Arithmetic involving Double and Float typically involves dereferencing the pointer and creating a new object to hold the result (depending on the circumstances). These extra overheads also affect the ratios in favor of the Double case.

Correctness

Having said all that, the most important thing is correctness, and this typically means getting the most accurate answer. And even if accuracy is not critical, it is usually not wrong to be "too accurate". So, the simple "rule of thumb" is to use double in preference to float, UNLESS there is an overriding performance requirement, AND you have solid evidence that using float will make a difference with respect to that requirement.

You should append to the table and not the rows.

<script type="text/javascript">
$('a').click(function() {
    $('#myTable').append('<tr class="child"><td>blahblah<\/td></tr>');
});
</script>

Some of the points in BadPirate's answer are only partially true:

1. For addSubView point

   addSubview causes layoutSubviews to be called on the view being added, the view it’s being added to (target view), and all the subviews of the target.

   It depends on the view's (target view) autoresize mask. If it has autoresize mask ON, layoutSubview will be called on each addSubview. If it has no autoresize mask then layoutSubview will be called only when the view's (target View) frame size changes.

   Example: if you created UIView programmatically (it has no autoresize mask by default), LayoutSubview will be called only when UIView frame changes not on every addSubview.

   It is through this technique that the performance of the application also increases.

2. For the device rotation point

   Rotating a device only calls layoutSubview on the parent view (the responding viewController's primary view)

   This can be true only when your VC is in the VC hierarchy (root at window.rootViewController), well this is most common case. In iOS 5, if you create a VC, but it is not added into any another VC, then this VC would not get any noticed when device rotate. Therefore its view would not get noticed by calling layoutSubviews.

1) It looks possible. This info on Github describes how to create a java program to send a message using the whatsapp encryption protocol from WhisperSystems.

2) No. See the whatsapp security white paper.

3) See #1.

Use below command on UNIX terminal :

java -XshowSettings

This will display all java properties and system settings. In this look for java.io.tmpdir value.

I know this is an old post, but figured I'd share my two cents. @Neji is correct in that you can use sessionStorage.getItem('label'), and sessionStorage.setItem('label', 'value') (although he had the setItem parameters backwards, not a big deal). I much more prefer the following, I think it's more succinct:

var val = sessionStorage.myValue

in place of getItem and

sessionStorage.myValue = 'value'

in place of setItem.

Also, it should be noted that in order to store JavaScript objects, they must be stringified to set them, and parsed to get them, like so:

sessionStorage.myObject = JSON.stringify(myObject); //will set object to the stringified myObject
var myObject = JSON.parse(sessionStorage.myObject); //will parse JSON string back to object

The reason is that sessionStorage stores everything as a string, so if you just say sessionStorage.object = myObject all you get is [object Object], which doesn't help you too much.

On wildfly 8 and later, go to /bin/standalone.conf and put your JAVA_OPTS there, with all you need.

Yes, there's a command git commit --amend which is used to "fix" last commit.

In your case it would be called as:

git add the_left_out_file
git commit --amend --no-edit

The --no-edit flag allow to make amendment to commit without changing commit message.

EDIT: Warning You should never amend public commits, that you already pushed to public repository, because what amend does is actually removing from history last commit and creating new commit with combined changes from that commit and new added when amending.

In Visual Studio you can use nuget to load the package

As none of the answers described a way to perform requests with OkHttp, which is very popular http client nowadays for Android and Java in general, I am going to provide a simple example:

//get an instance of the client
OkHttpClient client = new OkHttpClient();

//add parameters
HttpUrl.Builder urlBuilder = HttpUrl.parse("https://www.example.com").newBuilder();
urlBuilder.addQueryParameter("query", "stack-overflow");


String url = urlBuilder.build().toString();

//build the request
Request request = new Request.Builder().url(url).build();

//execute
Response response = client.newCall(request).execute();

The clear advantage of this library is that it abstracts us from some low level details, providing more friendly and secure ways to interact with them. The syntax is also simplified and permits to write nice code.

I already said that I was new to exec() function. After doing some more digging, I came upon 2>&1 which needs to be added at the end of command in exec().

Thanks @mattosmat for pointing it out in the comments too. I did not try this at once because you said it is a Linux command, I am on Windows.

So, what I have discovered, the command is actually executing in the back-end. That is why I could not see it actually running, which I was expecting to happen.

For all of you, who had similar problem, my advise is to use that command. It will point out all the errors and also tell you info/details about execution.

exec('some_command 2>&1', $output);
print_r($output);  // to see the response to your command

Thanks for all the help guys, I appreciate it ;)

I am new to retrofit and I am enjoying it. So here is a simple way to understand it for those that might want to query with more than one query: The ? and & are automatically added for you.

Interface:

 public interface IService {

      String BASE_URL = "https://api.test.com/";
      String API_KEY = "SFSDF24242353434";

      @GET("Search") //i.e https://api.test.com/Search?
      Call<Products> getProducts(@Query("one") String one, @Query("two") String two,    
                                @Query("key") String key)
}

It will be called this way. Considering you did the rest of the code already.

  Call<Results> call = service.productList("Whatever", "here", IService.API_KEY);

For example, when a query is returned, it will look like this.

//-> https://api.test.com/Search?one=Whatever&two=here&key=SFSDF24242353434

In your own (base) class, willSet and didSet are quite reduntant , as you could instead define a calculated property (i.e get- and set- methods) that access a _propertyVariable and does the desired pre- and post- prosessing.

If, however, you override a class where the property is already defined, then the willSet and didSet are useful and not redundant!

from django.db.models import Sum
Members.objects.annotate(total=Sum(designation))

first you need to import Sum then ..

Although all the approaches regarding the use of async: false are not good because of its deprecation and stuck the page untill the request comes back. Thus here are 2 ways to do it:

1st: Return whole ajax response in a function and then make use of done function to capture the response when the request is completed.(RECOMMENDED, THE BEST WAY)

function getAjax(url, data){
    return $.ajax({
        type: 'POST',
        url : url,              
        data: data,
        dataType: 'JSON',
        //async: true,  //NOT NEEDED
        success: function(response) {
            //Data = response;
        }
    });
 }

CALL THE ABOVE LIKE SO:

getAjax(youUrl, yourData).done(function(response){
    console.log(response);
});

FOR MULTIPLE AJAX CALLS MAKE USE OF $.when :

$.when( getAjax(youUrl, yourData), getAjax2(yourUrl2, yourData2) ).done(function(response){
    console.log(response);
});

2nd: Store the response in a cookie and then outside of the ajax call get that cookie value.(NOT RECOMMENDED)

        $.ajax({
            type: 'POST',
            url : url,              
            data: data,
            //async: false,    // No need to use this
            success: function(response) {
                Cookies.set(name, response);
            }
        });

        // Outside of the ajax call
        var response = Cookies.get(name);

NOTE: In the exmple above jquery cookies library is used.It is quite lightweight and works as snappy. Here is the link https://github.com/js-cookie/js-cookie

I too was looking for a good way to do this, I found the best way was to set a transition on the "transform" property and then change the transform and then remove the transition.

I put it all together in a jQuery plugin

https://gist.github.com/dustinpoissant/8a4837c476e3939a5b3d1a2585e8d1b0

You would use the code like this:

$("#myElement").animateTransform("rotate(180deg)", 750, function(){
  console.log("animation completed after 750ms");
});

I am trying to set a div to a certain percentage height in CSS

Percentage of what?

To set a percentage height, its parent element(*) must have an explicit height. This is fairly self-evident, in that if you leave height as auto, the block will take the height of its content... but if the content itself has a height expressed in terms of percentage of the parent you've made yourself a little Catch 22. The browser gives up and just uses the content height.

So the parent of the div must have an explicit height property. Whilst that height can also be a percentage if you want, that just moves the problem up to the next level.

If you want to make the div height a percentage of the viewport height, every ancestor of the div, including <html> and <body>, have to have height: 100%, so there is a chain of explicit percentage heights down to the div.

(*: or, if the div is positioned, the ‘containing block’, which is the nearest ancestor to also be positioned.)

Alternatively, all modern browsers and IE>=9 support new CSS units relative to viewport height (vh) and viewport width (vw):

div {
    height:100vh; 
}

See here for more info.

You need to link with the math library:

gcc -o sphere sphere.c -lm

The error you are seeing: error: ld returned 1 exit status is from the linker ld (part of gcc that combines the object files) because it is unable to find where the function pow is defined.

Including math.h brings in the declaration of the various functions and not their definition. The def is present in the math library libm.a. You need to link your program with this library so that the calls to functions like pow() are resolved.

As Jage's answer removes the element completely, including event handlers and data, I'm adding a simple solution that doesn't do that, thanks to the detach function.

var element = $('#childNode').detach();
$('#parentNode').append(element);

Edit:

Igor Mukhin suggested an even shorter version in the comments below:

$("#childNode").detach().appendTo("#parentNode");

Try this, in your parent frame set up you IFRAMEs like this:

<iframe id="frame1" src="inner.html#frame1"></iframe>
<iframe id="frame2" src="inner.html#frame2"></iframe>
<iframe id="frame3" src="inner.html#frame3"></iframe>

Note that the id of each frame is passed as an anchor in the src.

then in your inner html you can access the id of the frame it is loaded in via location.hash:

<button onclick="alert('I am frame: ' + location.hash.substr(1))">Who Am I?</button>

then you can access parent.document.getElementById() to access the iframe tag from inside the iframe

How to find out what this MySQL Error is trying to say:

#1064 - You have an error in your SQL syntax;

This error has no clues in it. You have to double check all of these items to see where your mistake is:

1. You have omitted, or included an unnecessary symbol: !@#$%^&*()-_=+[]{}\|;:'",<>/?
2. A misplaced, missing or unnecessary keyword: select, into, or countless others.
3. You have unicode characters that look like ascii characters in your query but are not recognized.
4. Misplaced, missing or unnecessary whitespace or newlines between keywords.
5. Unmatched single quotes, double quotes, parenthesis or braces.

Take away as much as you can from the broken query until it starts working. And then use PostgreSQL next time that has a sane syntax reporting system.

We can easily do that in css3. We have to simply use @import statement. The following video easily describes the way how to do that. so go ahead and watch it out.

You can't... an array's size is always fixed in Java. Typically instead of using an array, you'd use an implementation of List<T> here - usually ArrayList<T>, but with plenty of other alternatives available.

You can create an array from the list as a final step, of course - or just change the signature of the method to return a List<T> to start with.

This worked for me

import subprocess
import sys
HOST="IP"
COMMAND="ifconfig"

def passwordless_ssh(HOST):
        ssh = subprocess.Popen(["ssh", "%s" % HOST, COMMAND],
                       shell=False,
                       stdout=subprocess.PIPE,
                       stderr=subprocess.PIPE)
        result = ssh.stdout.readlines()
        if result == []:
                error = ssh.stderr.readlines()
                print >>sys.stderr, "ERROR: %s" % error
                return "error"
        else:
                return result

Use the date function:

select date(timestamp_field) from table

From a character field representation to a date you can use:

select date(substring('2011/05/26 09:00:00' from 1 for 10));

Test code:

create table test_table (timestamp_field timestamp);
insert into test_table (timestamp_field) values(current_timestamp);
select timestamp_field, date(timestamp_field) from test_table;

Test result:

* Uses proxy env variable http_proxy == 'https://proxy.in.tum.de:8080'   
                                         ^^^^^

The https:// is wrong, it should be http://. The proxy itself should be accessed by HTTP and not HTTPS even though the target URL is HTTPS. The proxy will nevertheless properly handle HTTPS connection and keep the end-to-end encryption. See HTTP CONNECT method for details how this is done.

You can use foreignobject for more control and placing rich HTML content over rect or circle

    <svg width="250" height="250" xmlns="http://www.w3.org/2000/svg">_x000D_
        <rect x="0" y="0" width="250" height="250" fill="aquamarine" />_x000D_
        <foreignobject x="0" y="0" width="250" height="250">_x000D_
            <body xmlns="http://www.w3.org/1999/xhtml">_x000D_
                <div>Here is a long text that runs more than one line and works as a paragraph</div>_x000D_

Executive summary / TL;DR:
Try doing a find & replace of "=" with "=". Yes, replace the equals sign with itself. For my scenario, it forced everything to update.

Background:
I frequently make formulas across multiple columns then concatenate them together. After doing such, I'll copy & paste them as values to extract my created formula. After this process, they're typically stuck displaying a formula, and not displaying a value, unless I enter the cell and press Enter. Pressing F2 & Enter repeatedly is not fun.

For those who are having trouble indenting phpstorm here I have a tip and I hope they help ...

First you have to go to file-> settings-> keymap-> select-> windows.

If they are on the windows machine. If you are on mac and choose macos.

 $deleted = $_POST['checkbox'];
 $sql = "DELETE FROM $tbl_name WHERE id IN (".implode(",", $deleted ) . ")";

For each form data key you can set Content-Type, there is a postman button on the right to add the Content-Type column, and you don't have to parse a json from a string inside your Controller.

Check your keystore file for first, in you example you creating file with name my-release-key.keystore. If its correct and really present in folder Users/bournewang/Documents/Project check alias, in your example it is -alias alias_name, but in config you specified alias mike

you can use ps.
e.g. having python process with two busy threads on dual core CPU:

$ ps -p 29492 -L -o pid,tid,psr,pcpu
  PID   TID PSR %CPU
29492 29492   1  0.0
29492 29493   1 48.7
29492 29494   1 51.9

(PSR is CPU id the thread is currently assigned to)

you see that the threads are running on the same cpu core (because of GIL)

running the same python script in jython, we see, that the script is utilizing both cores (and there are many other service or whatever threads, which are almost idle):

$ ps -p 28671 -L -o pid,tid,psr,pcpu
  PID   TID PSR %CPU
28671 28671   1  0.0
28671 28672   0  4.4
28671 28673   0  0.6
28671 28674   0  0.5
28671 28675   0  2.3
28671 28676   0  0.0
28671 28677   1  0.0
28671 28678   1  0.0
28671 28679   0  4.6
28671 28680   0  4.4
28671 28681   1  0.0
28671 28682   1  0.0
28671 28721   1  0.0
28671 28729   0 88.6
28671 28730   1 88.5

you can process the output and calculate the total CPU for each CPU core.

Unfortunately, this approach does not seem to be 100% reliable, sometimes i see that in the first case, the two working threads are reported to be separated to each CPU core, or in the latter case, the two threads are reported to be on the same core..

The registry is the official way to detect if a specific version of the Framework is installed.

Which registry keys are needed change depending on the Framework version you are looking for:

Framework Version  Registry Key
------------------------------------------------------------------------------------------
1.0                HKLM\Software\Microsoft\.NETFramework\Policy\v1.0\3705 
1.1                HKLM\Software\Microsoft\NET Framework Setup\NDP\v1.1.4322\Install 
2.0                HKLM\Software\Microsoft\NET Framework Setup\NDP\v2.0.50727\Install 
3.0                HKLM\Software\Microsoft\NET Framework Setup\NDP\v3.0\Setup\InstallSuccess 
3.5                HKLM\Software\Microsoft\NET Framework Setup\NDP\v3.5\Install 
4.0 Client Profile HKLM\Software\Microsoft\NET Framework Setup\NDP\v4\Client\Install
4.0 Full Profile   HKLM\Software\Microsoft\NET Framework Setup\NDP\v4\Full\Install

Generally you are looking for:

"Install"=dword:00000001

except for .NET 1.0, where the value is a string (REG_SZ) rather than a number (REG_DWORD).

Determining the service pack level follows a similar pattern:

Framework Version  Registry Key
------------------------------------------------------------------------------------------
1.0                HKLM\Software\Microsoft\Active Setup\Installed Components\{78705f0d-e8db-4b2d-8193-982bdda15ecd}\Version 
1.0[1]             HKLM\Software\Microsoft\Active Setup\Installed Components\{FDC11A6F-17D1-48f9-9EA3-9051954BAA24}\Version 
1.1                HKLM\Software\Microsoft\NET Framework Setup\NDP\v1.1.4322\SP 
2.0                HKLM\Software\Microsoft\NET Framework Setup\NDP\v2.0.50727\SP 
3.0                HKLM\Software\Microsoft\NET Framework Setup\NDP\v3.0\SP 
3.5                HKLM\Software\Microsoft\NET Framework Setup\NDP\v3.5\SP 
4.0 Client Profile HKLM\Software\Microsoft\NET Framework Setup\NDP\v4\Client\Servicing
4.0 Full Profile   HKLM\Software\Microsoft\NET Framework Setup\NDP\v4\Full\Servicing

[1] Windows Media Center or Windows XP Tablet Edition

As you can see, determining the SP level for .NET 1.0 changes if you are running on Windows Media Center or Windows XP Tablet Edition. Again, .NET 1.0 uses a string value while all of the others use a DWORD.

For .NET 1.0 the string value at either of these keys has a format of #,#,####,#. The last # is the Service Pack level.

While I didn't explicitly ask for this, if you want to know the exact version number of the Framework you would use these registry keys:

Framework Version  Registry Key
------------------------------------------------------------------------------------------
1.0                HKLM\Software\Microsoft\Active Setup\Installed Components\{78705f0d-e8db-4b2d-8193-982bdda15ecd}\Version 
1.0[1]             HKLM\Software\Microsoft\Active Setup\Installed Components\{FDC11A6F-17D1-48f9-9EA3-9051954BAA24}\Version 
1.1                HKLM\Software\Microsoft\NET Framework Setup\NDP\v1.1.4322 
2.0[2]             HKLM\Software\Microsoft\NET Framework Setup\NDP\v2.0.50727\Version 
2.0[3]             HKLM\Software\Microsoft\NET Framework Setup\NDP\v2.0.50727\Increment
3.0                HKLM\Software\Microsoft\NET Framework Setup\NDP\v3.0\Version 
3.5                HKLM\Software\Microsoft\NET Framework Setup\NDP\v3.5\Version 
4.0 Client Profile HKLM\Software\Microsoft\NET Framework Setup\NDP\v4\Version 
4.0 Full Profile   HKLM\Software\Microsoft\NET Framework Setup\NDP\v4\Version 

[1] Windows Media Center or Windows XP Tablet Edition
[2] .NET 2.0 SP1
[3] .NET 2.0 Original Release (RTM)

Again, .NET 1.0 uses a string value while all of the others use a DWORD.

Additional Notes

• for .NET 1.0 the string value at either of these keys has a format of #,#,####,#. The #,#,#### portion of the string is the Framework version.

• for .NET 1.1, we use the name of the registry key itself, which represents the version number.

• Finally, if you look at dependencies, .NET 3.0 adds additional functionality to .NET 2.0 so both .NET 2.0 and .NET 3.0 must both evaulate as being installed to correctly say that .NET 3.0 is installed. Likewise, .NET 3.5 adds additional functionality to .NET 2.0 and .NET 3.0, so .NET 2.0, .NET 3.0, and .NET 3. should all evaluate to being installed to correctly say that .NET 3.5 is installed.

• .NET 4.0 installs a new version of the CLR (CLR version 4.0) which can run side-by-side with CLR 2.0.

Update for .NET 4.5

There won't be a v4.5 key in the registry if .NET 4.5 is installed. Instead you have to check if the HKLM\Software\Microsoft\NET Framework Setup\NDP\v4\Full key contains a value called Release. If this value is present, .NET 4.5 is installed, otherwise it is not. More details can be found here and here.

Another approach with very few code (using Array reduce and Array includes):

arr1.length == arr2.length && arr1.reduce((a, b) => a && arr2.includes(b), true)

If you want to compare also the equality of order:

arr1.length == arr2.length && arr1.reduce((a, b, i) => a && arr2[i], true)

• The length check ensures that the set of elements in one array isn't just a subset of the other one.

• The reducer is used to walk through one array and search for each item in other array. If one item isn't found the reduce function returns false.

  1. In the first example it's being tested that an element is included
  2. The second example check for the order too

Or you could catch a failed attempt to cast into E eg.

public int indexOf(Object arg0){
  try{
    E test=(E)arg0;
    return doStuff(test);
  }catch(ClassCastException e){
    return -1;
  }
}

My error was calling NgbModal open method with incorrect parameters from .html

I recommend not using WebClient.DownloadString. This is because (at least in .NET 3.5) DownloadString is not smart enough to use/remove the BOM, should it be present. This can result in the BOM () incorrectly appearing as part of the string when UTF-8 data is returned (at least without a charset) - ick!

Instead, this slight variation will work correctly with BOMs:

string ReadTextFromUrl(string url) {
    // WebClient is still convenient
    // Assume UTF8, but detect BOM - could also honor response charset I suppose
    using (var client = new WebClient())
    using (var stream = client.OpenRead(url))
    using (var textReader = new StreamReader(stream, Encoding.UTF8, true)) {
        return textReader.ReadToEnd();
    }
}

In angular 2 we don't have pre-defined filter and order by as it was with AngularJs, we need to create it for our requirements. It is time killing but we need to do it, (see No FilterPipe or OrderByPipe). In this article we are going to see how we can create filter called pipe in angular 2 and sorting feature called Order By. Let's use a simple dummy json data array for it. Here is the json we will use for our example

First we will see how to use the pipe (filter) by using the search feature:

Create a component with name category.component.ts

    import { Component, OnInit } from '@angular/core';_x000D_
    @Component({_x000D_
      selector: 'app-category',_x000D_
      templateUrl: './category.component.html'_x000D_
    })_x000D_
    export class CategoryComponent implements OnInit {_x000D_
_x000D_
      records: Array<any>;_x000D_
      isDesc: boolean = false;_x000D_
      column: string = 'CategoryName';_x000D_
      constructor() { }_x000D_
_x000D_
      ngOnInit() {_x000D_
        this.records= [_x000D_
          { CategoryID: 1,  CategoryName: "Beverages", Description: "Coffees, teas" },_x000D_
          { CategoryID: 2,  CategoryName: "Condiments", Description: "Sweet and savory sauces" },_x000D_
          { CategoryID: 3,  CategoryName: "Confections", Description: "Desserts and candies" },_x000D_
          { CategoryID: 4,  CategoryName: "Cheeses",  Description: "Smetana, Quark and Cheddar Cheese" },_x000D_
          { CategoryID: 5,  CategoryName: "Grains/Cereals", Description: "Breads, crackers, pasta, and cereal" },_x000D_
          { CategoryID: 6,  CategoryName: "Beverages", Description: "Beers, and ales" },_x000D_
          { CategoryID: 7,  CategoryName: "Condiments", Description: "Selishes, spreads, and seasonings" },_x000D_
          { CategoryID: 8,  CategoryName: "Confections", Description: "Sweet breads" },_x000D_
          { CategoryID: 9,  CategoryName: "Cheeses",  Description: "Cheese Burger" },_x000D_
          { CategoryID: 10, CategoryName: "Grains/Cereals", Description: "Breads, crackers, pasta, and cereal" }_x000D_
         ];_x000D_
         // this.sort(this.column);_x000D_
      }_x000D_
    }

<div class="col-md-12">_x000D_
  <table class="table table-responsive table-hover">_x000D_
    <tr>_x000D_
      <th >Category ID</th>_x000D_
      <th>Category</th>_x000D_
      <th>Description</th>_x000D_
    </tr>_x000D_
    <tr *ngFor="let item of records">_x000D_
      <td>{{item.CategoryID}}</td>_x000D_
      <td>{{item.CategoryName}}</td>_x000D_
      <td>{{item.Description}}</td>_x000D_
    </tr>_x000D_
  </table>_x000D_
</div>

2.Nothing special in this code just initialize our records variable with a list of categories, two other variables isDesc and column are declared which we will use for sorting latter. At the end added this.sort(this.column); latter we will use, once we will have this method.

Note templateUrl: './category.component.html', which we will create next to show the records in tabluar format.

For this create a HTML page called category.component.html, whith following code:

3.Here we use ngFor to repeat the records and show row by row, try to run it and we can see all records in a table.

Search - Filter Records

Say we want to search the table by category name, for this let's add one text box to type and search

<div class="form-group">_x000D_
  <div class="col-md-6" >_x000D_
    <input type="text" [(ngModel)]="searchText" _x000D_
           class="form-control" placeholder="Search By Category" />_x000D_
  </div>_x000D_
</div>

5.Now we need to create a pipe to search the result by category because filter is not available as it was in angularjs any more.

Create a file category.pipe.ts and add following code in it.

    import { Pipe, PipeTransform } from '@angular/core';_x000D_
    @Pipe({ name: 'category' })_x000D_
    export class CategoryPipe implements PipeTransform {_x000D_
      transform(categories: any, searchText: any): any {_x000D_
        if(searchText == null) return categories;_x000D_
_x000D_
        return categories.filter(function(category){_x000D_
          return category.CategoryName.toLowerCase().indexOf(searchText.toLowerCase()) > -1;_x000D_
        })_x000D_
      }_x000D_
    }

6.Here in transform method we are accepting the list of categories and search text to search/filter record on the list. Import this file into our category.component.ts file, we want to use it here, as follows:

import { CategoryPipe } from './category.pipe';_x000D_
@Component({      _x000D_
  selector: 'app-category',_x000D_
  templateUrl: './category.component.html',_x000D_
  pipes: [CategoryPipe]   // This Line       _x000D_
})

7.Our ngFor loop now need to have our Pipe to filter the records so change it to this.You can see the output in image below

enter image description here

If $a is the array that's passed, $a[76][0]['id'] should give '76' and $a[76][1]['id'] should give '81', but I can't test as I don't have PHP installed on this machine.

java.util.Date date;
Timestamp timestamp = resultSet.getTimestamp(i);
if (timestamp != null)
    date = new java.util.Date(timestamp.getTime()));

Then format it the way you like.

you can try this... ALTER TABLE Your_Table ADD table_ID int NOT NULL PRIMARY KEY auto_increment;

This worked for me. The key is to use * as Row height.

<Grid x:Name="grid">
        <Grid.RowDefinitions>
            <RowDefinition Height="60"/>
            <RowDefinition Height="*"/>
            <RowDefinition Height="10"/>
        </Grid.RowDefinitions>

        <TabControl  Grid.Row="1" x:Name="tabItem">
                <TabItem x:Name="ta" 
                        Header="List of all Clients">
                        <DataGrid Name="clientsgrid" AutoGenerateColumns="True" Margin="2" 
                         ></DataGrid>
                </TabItem>
        </TabControl>
    
    </Grid>

In your pom.xml you should add distributionManagement configuration to where to deploy.

In the following example I have used file system as the locations.

<distributionManagement>
       <repository>
         <id>internal.repo</id>
         <name>Internal repo</name>
         <url>file:///home/thara/testesb/in</url>
       </repository>
   </distributionManagement>

you can add another location while deployment by using the following command (but to avoid above error you should have at least 1 repository configured) :

mvn deploy -DaltDeploymentRepository=internal.repo::default::file:///home/thara/testesb/in

Your array has default keys(0,1) which store object {'com':'some thing'} use:

var obj = jQuery.parseJSON(response);
$.each(obj, function(key,value) {
  alert(value.com);
}); 

Calling virtual functions from a constructor or destructor is dangerous and should be avoided whenever possible. All C++ implementations should call the version of the function defined at the level of the hierarchy in the current constructor and no further.

The C++ FAQ Lite covers this in section 23.7 in pretty good detail. I suggest reading that (and the rest of the FAQ) for a followup.

Excerpt:

[...] In a constructor, the virtual call mechanism is disabled because overriding from derived classes hasn’t yet happened. Objects are constructed from the base up, “base before derived”.

[...]

Destruction is done “derived class before base class”, so virtual functions behave as in constructors: Only the local definitions are used – and no calls are made to overriding functions to avoid touching the (now destroyed) derived class part of the object.

EDIT Corrected Most to All (thanks litb)

Notice that '10' is the representation of the base in that base:

10 is 2(decimal) in base-2

10 is 3(decimal) in base-3

...

10 is 10(decimal) in base-10

...

10 is 16(decimal) in base-16 (hexadecimal)

...

10 is 1024(decimal) in base-1024

...and so on

If you are in a Linux container, such as on a Chromebook, you will need to manually browse to your localhost's address. I am aware the newer Chrome OS versions no longer have this problem, but on my Chromebook, I still had to manually browse to the localhost's address for your code to work.

To browse to your locahost's address, type this in command line: sudo ifconfig

and note the inet address under eth0.

Otherwise, as others have noted, simply type node.js filename and it will work as long as you point the browser to the proper address.

Hope this helps!

            return res.status(401).json({message:'Auth failed'});
        }
        next();   
        }

` in the above calling next() twice will raise an error

2. router.delete('/:orderId', (req, res, next) => { Order.remove({_id:req.params.orderId},(err,data)=>{ if(err){ **res.status(500).json(err);** }else{ res.status(200).json(data); } *res.status(200).json(data);* }) })

here respond is send twice check whether you already sent a response

This is the reply I received from Github when I asked them to delete a pull request:

"Thanks for getting in touch! Pull requests can't be deleted through the UI at the moment and we'll only delete pull requests when they contain sensitive information like passwords or other credentials."

It will works for all version of twitterbootstrap

Javascript code :

<script type="text/javascript">
/* <![CDATA[ */
(function(){
   var bsModal = null;
   $("[data-toggle=modal]").click(function(e) {
      e.preventDefault();
      var trgId = $(this).attr('data-target'); 
      if ( bsModal == null ) 
       bsModal = $(trgId).modal;
      $.fn.bsModal = bsModal;
      $(trgId + " .modal-body").load($(this).attr("href"));
      $(trgId).bsModal('show');
    });
 })();
/* <![CDATA[ */
</script>

links to modal are

<a data-toggle="modal" data-target="#myModal" href="edit1.aspx">Open modal 1</a>
<a data-toggle="modal" data-target="#myModal" href="edit2.aspx">Open modal 2</a>
<a data-toggle="modal" data-target="#myModal" href="edit3.aspx">Open modal 3</a>

pop up modal

<div id="myModal" class="modal hide fade in">
<div class="modal-header">
    <a class="close" data-dismiss="modal">×</a>
    <h3>Header</h3>
</div>
<div class="modal-body"></div>
<div class="modal-footer">
    <input type="submit" class="btn btn-success" value="Save"/>
</div>

Use .length refer to http://api.jquery.com/checked-selector/

if ($('input[name="html_elements"]:checked').length === 0) alert("Not checked");
else alert("Checked");

When building big tables speed is a concern so Jamie Dixon's second function is best, but it doesn't completely work as is...

It fails to take all of the letters to lowercase, and it only capitalizes the first letter of the string, not the first letter of each word in the string... the below option fixes both issues:

    public string UppercaseFirstEach(string s)
    {
        char[] a = s.ToLower().ToCharArray();

        for (int i = 0; i < a.Count(); i++ )
        {
            a[i] = i == 0 || a[i-1] == ' ' ? char.ToUpper(a[i]) : a[i];

        }

        return new string(a);
    }

Although at this point, whether this is still the fastest option is uncertain, the Regex solution provided by George Mauer might be faster... someone who cares enough should test it.

indentation is important in Python. Your if else statement should be within triple arrow (>>>), In Mac python IDLE version 3.7.4 elif statement doesn't comes with correct indentation when you go on next line you have to shift left to avoid syntax error.

Hint: If you have more than one connection property then separate them with:

&

To give you somthing like:

url="jdbc:mysql://localhost/glyndwr?autoReconnect=true&allowMultiQueries=true"

I hope this helps some one.

You can't disable a link (in a portable way). You can use one of these techniques (each one with its own benefits and disadvantages).

CSS way

This should be the right way (but see later) to do it when most of browsers will support it:

a.disabled {
    pointer-events: none;
}

It's what, for example, Bootstrap 3.x does. Currently (2016) it's well supported only by Chrome, FireFox and Opera (19+). Internet Explorer started to support this from version 11 but not for links however it's available in an outer element like:

span.disable-links {
    pointer-events: none;
}

With:

<span class="disable-links"><a href="#">...</a></span>

Workaround

We, probably, need to define a CSS class for pointer-events: none but what if we reuse the disabled attribute instead of a CSS class? Strictly speaking disabled is not supported for <a> but browsers won't complain for unknown attributes. Using the disabled attribute IE will ignore pointer-events but it will honor IE specific disabled attribute; other CSS compliant browsers will ignore unknown disabled attribute and honor pointer-events. Easier to write than to explain:

a[disabled] {
    pointer-events: none;
}

Another option for IE 11 is to set display of link elements to block or inline-block:

<a style="pointer-events: none; display: inline-block;" href="#">...</a>

Note that this may be a portable solution if you need to support IE (and you can change your HTML) but...

All this said please note that pointer-events disables only...pointer events. Links will still be navigable through keyboard then you also need to apply one of the other techniques described here.

Focus

In conjunction with above described CSS technique you may use tabindex in a non-standard way to prevent an element to be focused:

<a href="#" disabled tabindex="-1">...</a>

I never checked its compatibility with many browsers then you may want to test it by yourself before using this. It has the advantage to work without JavaScript. Unfortunately (but obviously) tabindex cannot be changed from CSS.

Intercept clicks

Use a href to a JavaScript function, check for the condition (or the disabled attribute itself) and do nothing in case.

$("td > a").on("click", function(event){
    if ($(this).is("[disabled]")) {
        event.preventDefault();
    }
});

To disable links do this:

$("td > a").attr("disabled", "disabled");

To re-enable them:

$("td > a").removeAttr("disabled");

If you want instead of .is("[disabled]") you may use .attr("disabled") != undefined (jQuery 1.6+ will always return undefined when the attribute is not set) but is() is much more clear (thanks to Dave Stewart for this tip). Please note here I'm using the disabled attribute in a non-standard way, if you care about this then replace attribute with a class and replace .is("[disabled]") with .hasClass("disabled") (adding and removing with addClass() and removeClass()).

Zoltán Tamási noted in a comment that "in some cases the click event is already bound to some "real" function (for example using knockoutjs) In that case the event handler ordering can cause some troubles. Hence I implemented disabled links by binding a return false handler to the link's touchstart, mousedown and keydown events. It has some drawbacks (it will prevent touch scrolling started on the link)" but handling keyboard events also has the benefit to prevent keyboard navigation.

Note that if href isn't cleared it's possible for the user to manually visit that page.

Clear the link

Clear the href attribute. With this code you do not add an event handler but you change the link itself. Use this code to disable links:

$("td > a").each(function() {
    this.data("href", this.attr("href"))
        .attr("href", "javascript:void(0)")
        .attr("disabled", "disabled");
});

And this one to re-enable them:

$("td > a").each(function() {
    this.attr("href", this.data("href")).removeAttr("disabled");
});

Personally I do not like this solution very much (if you do not have to do more with disabled links) but it may be more compatible because of various way to follow a link.

Fake click handler

Add/remove an onclick function where you return false, link won't be followed. To disable links:

$("td > a").attr("disabled", "disabled").on("click", function() {
    return false; 
});

To re-enable them:

$("td > a").removeAttr("disabled").off("click");

I do not think there is a reason to prefer this solution instead of the first one.

Styling

Styling is even more simple, whatever solution you're using to disable the link we did add a disabled attribute so you can use following CSS rule:

a[disabled] {
    color: gray;
}

If you're using a class instead of attribute:

a.disabled {
    color: gray;
}

If you're using an UI framework you may see that disabled links aren't styled properly. Bootstrap 3.x, for example, handles this scenario and button is correctly styled both with disabled attribute and with .disabled class. If, instead, you're clearing the link (or using one of the others JavaScript techniques) you must also handle styling because an <a> without href is still painted as enabled.

Accessible Rich Internet Applications (ARIA)

Do not forget to also include an attribute aria-disabled="true" together with disabled attribute/class.

Try to use limit in your query. It's because of full disk as said by @Monsters X.

I have also faced this problem and solved by limit in query, because the thousands of records were there. Now working good :)

Have a look at this;

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

This might not be the right way to do it, but I'd do something like;

Actual code;

from multiprocessing import Process, JoinableQueue as Queue 

class CustomWorker(Process):
    def __init__(self,workQueue, out1,out2,out3):
        Process.__init__(self)
        self.input=workQueue
        self.out1=out1
        self.out2=out2
        self.out3=out3
    def run(self):
            while True:
                try:
                    value = self.input.get()
                    #value modifier
                    temp1,temp2,temp3 = self.calc_stuff(value)
                    self.out1.put(temp1)
                    self.out2.put(temp2)
                    self.out3.put(temp3)
                    self.input.task_done()
                except Queue.Empty:
                    return
                   #Catch things better here
    def calc_stuff(self,param):
        out1 = param * 2
        out2 = param * 4
        out3 = param * 8
        return out1,out2,out3
def Main():
    inputQueue = Queue()
    for i in range(10):
        inputQueue.put(i)
    out1 = Queue()
    out2 = Queue()
    out3 = Queue()
    processes = []
    for x in range(2):
          p = CustomWorker(inputQueue,out1,out2,out3)
          p.daemon = True
          p.start()
          processes.append(p)
    inputQueue.join()
    while(not out1.empty()):
        print out1.get()
        print out2.get()
        print out3.get()
if __name__ == '__main__':
    Main()

Hope that helps.

Here is a function that even supports clockwise/anticlockwise drawing do that you control fills with the non-zero winding rule.

Here is a full article on how it works and more.

// Defines a path for any regular polygon with the specified number of sides and radius, 
// centered on the provide x and y coordinates.
// optional parameters: startAngle and anticlockwise

function polygon(ctx, x, y, radius, sides, startAngle, anticlockwise) {
  if (sides < 3) return;
  var a = (Math.PI * 2)/sides;
  a = anticlockwise?-a:a;
  ctx.save();
  ctx.translate(x,y);
  ctx.rotate(startAngle);
  ctx.moveTo(radius,0);
  for (var i = 1; i < sides; i++) {
    ctx.lineTo(radius*Math.cos(a*i),radius*Math.sin(a*i));
  }
  ctx.closePath();
  ctx.restore();
}

// Example using the function.
// Define a path in the shape of a pentagon and then fill and stroke it.
context.beginPath();
polygon(context,125,125,100,5,-Math.PI/2);
context.fillStyle="rgba(227,11,93,0.75)";
context.fill();
context.stroke();

Here's a slightly more flexible approach using the match method. With this, you can extract more than one string:

s = "<ants> <pants>"
matchdata = s.match(/<([^>]*)> <([^>]*)>/)

# Use 'captures' to get an array of the captures
matchdata.captures   # ["ants","pants"]

# Or use raw indices
matchdata[0]   # whole regex match: "<ants> <pants>"
matchdata[1]   # first capture: "ants"
matchdata[2]   # second capture: "pants"

Okay, I was blind:

Nothing compares to extjs in terms of community size and presence on StackOverflow. Despite previous controversy, Ext JS now has a GPLv3 open source license. Its learning curve is long, but it can be quite rewarding once learned. Ext JS lacks a Material Design theme, and the team has repeatedly refused to release the source code on GitHub. For mobile, one must use the separate Sencha Touch library.

Have in mind also that,

large JavaScript libraries, such as YUI, have been receiving less attention from the community. Many developers today look at large JavaScript libraries as walled gardens they don’t want to be locked into.

-- Announcement of YUI development being ceased

That said, below are a number of Ext JS alternatives currently available.

Leading client widget libraries

1. Blueprint is a React-based UI toolkit developed by big data analytics company Palantir in TypeScript, and "optimized for building complex data-dense interfaces for desktop applications". Actively developed on GitHub as of May 2019, with comprehensive documentation. Components range from simple (chips, toast, icons) to complex (tree, data table, tag input with autocomplete, date range picker. No accordion or resizer.

   Blueprint targets modern browsers (Chrome, Firefox, Safari, IE 11, and Microsoft Edge) and is licensed under a modified Apache license.

   Sandbox / demo • GitHub • Docs

2. Webix - an advanced, easy to learn, mobile-friendly, responsive and rich free&open source JavaScript UI components library. Webix spun off from DHTMLX Touch (a project with 8 years of development behind it - see below) and went on to become a standalone UI components framework. The GPL3 edition allows commercial use and lets non-GPL applications using Webix keep their license, e.g. MIT, via a license exemption for FLOSS. Webix has 55 UI widgets, including trees, grids, treegrids and charts. Funding comes from a commercial edition with some advanced widgets (Pivot, Scheduler, Kanban, org chart etc.). Webix has an extensive list of free and commercial widgets, and integrates with most popular frameworks (React, Vue, Meteor, etc) and UI components.

   

   Skins look modern, and include a Material Design theme. The Touch theme also looks quite Material Design-ish. See also the Skin Builder.

   Minimal GitHub presence, but includes the library code, and the documentation (which still needs major improvements). Webix suffers from a having a small team and a lack of marketing. However, they have been responsive to user feedback, both on GitHub and on their forum.

   The library was lean (128Kb gzip+minified for all 55 widgets as of ~2015), faster than ExtJS, dojo and others, and the design is pleasant-looking. The current version of Webix (v6, as of Nov 2018) got heavier (400 - 676kB minified but NOT gzipped).

   The demos on Webix.com look and function great. The developer, XB Software, uses Webix in solutions they build for paying customers, so there's likely a good, funded future ahead of it.

   Webix aims for backwards compatibility down to IE8, and as a result carries some technical debt.

3. react-md - MIT-licensed Material Design UI components library for React. Responsive, accessible. Implements components from simple (buttons, cards) to complex (sortable tables, autocomplete, tags input, calendars). One lead author, ~1900 GitHub stars.

4. kendo - jQuery-based UI toolkit with 40+ basic open-source widgets, plus commercial professional widgets (grids, trees, charts etc.). Responsive&mobile support. Works with Bootstrap and AngularJS. Modern, with Material Design themes. The documentation is available on GitHub, which has enabled numerous contributions from users (4500+ commits, 500+ PRs as of Jan 2015).

   

   Well-supported commercially, claiming millions of developers, and part of a large family of developer tools. Telerik has received many accolades, is a multi-national company (Bulgaria, US), was acquired by Progress Software, and is a thought leader.

   A Kendo UI Professional developer license costs $700 and posting access to most forums is conditioned upon having a license or being in the trial period.

   [Wikipedia] • GitHub/Telerik • Demos • Playground • Tools

5. OpenUI5 - jQuery-based UI framework with 180 widgets, Apache 2.0-licensed and fully-open sourced and funded by German software giant SAP SE.

   

   The community is much larger than that of Webix, SAP is hiring developers to grow OpenUI5, and they presented OpenUI5 at OSCON 2014.

   The desktop themes are rather lackluster, but the Fiori design for web and mobile looks clean and neat.

   Wikipedia • GitHub • Mobile-first controls demos • Desktop controls demos • SO

6. DHTMLX - JavaScript library for building rich Web and Mobile apps. Looks most like ExtJS - check the demos. Has been developed since 2005 but still looks modern. All components except TreeGrid are available under GPLv2 but advanced features for many components are only available in the commercial PRO edition - see for example the tree. Claims to be used by many Fortune 500 companies.

   

   Minimal presence on GitHub (the main library code is missing) and StackOverflow but active forum. The documentation is not available on GitHub, which makes it difficult to improve by the community.

7. Polymer, a Web Components polyfill, plus Polymer Paper, Google's implementation of the Material design. Aimed at web and mobile apps. Doesn't have advanced widgets like trees or even grids but the controls it provides are mobile-first and responsive. Used by many big players, e.g. IBM or USA Today.

   

8. Ant Design claims it is "a design language for background applications", influenced by "nature" and helping designers "create low-entropy atmosphere for developer team". That's probably a poor translation from Chinese for "UI components for enterprise web applications". It's a React UI library written in TypeScript, with many components, from simple (buttons, cards) to advanced (autocomplete, calendar, tag input, table).

   The project was born in China, is popular with Chinese companies, and parts of the documentation are available only in Chinese. Quite popular on GitHub, yet it makes the mistake of splitting the community into Chinese and English chat rooms. The design looks Material-ish, but fonts are small and the information looks lost in a see of whitespace.

9. PrimeUI - collection of 45+ rich widgets based on jQuery UI. Apache 2.0 license. Small GitHub community. 35 premium themes available.

10. qooxdoo - "a universal JavaScript framework with a coherent set of individual components", developed and funded by German hosting provider 1&1 (see the contributors, one of the world's largest hosting companies. GPL/EPL (a business-friendly license).

    Mobile themes look modern but desktop themes look old (gradients).

11. jQuery UI - easy to pick up; looks a bit dated; lacks advanced widgets. Of course, you can combine it with independent widgets for particular needs, e.g. trees or other UI components, but the same can be said for any other framework.

12. angular + Angular UI. While Angular is backed by Google, it's being radically revamped in the upcoming 2.0 version, and "users will need to get to grips with a new kind of architecture. It's also been confirmed that there will be no migration path from Angular 1.X to 2.0". Moreover, the consensus seems to be that Angular 2 won't really be ready for use until a year or two from now. Angular UI has relatively few widgets (no trees, for example).

13. DojoToolkit and their powerful Dijit set of widgets. Completely open-sourced and actively developed on GitHub, but development is now (Nov 2018) focused on the new dojo.io framework, which has very few basic widgets. BSD/AFL license. Development started in 2004 and the Dojo Foundation is being sponsored by IBM, Google, and others - see Wikipedia. 7500 questions here on SO.

    

    Themes look desktop-oriented and dated - see the theme tester in dijit. The official theme previewer is broken and only shows "Claro". A Bootstrap theme exists, which looks a lot like Bootstrap, but doesn't use Bootstrap classes. In Jan 2015, I started a thread on building a Material Design theme for Dojo, which got quite popular within the first hours. However, there are questions regarding building that theme for the current Dojo 1.10 vs. the next Dojo 2.0. The response to that thread shows an active and wide community, covering many time zones.

    Unfortunately, Dojo has fallen out of popularity and fewer companies appear to use it, despite having (had?) a strong foothold in the enterprise world. In 2009-2012, its learning curve was steep and the documentation needed improvements; while the documentation has substantially improved, it's unclear how easy it is to pick up Dojo nowadays.

    With a Material Design theme, Dojo (2.0?) might be the killer UI components framework.

14. Enyo - front-end library aimed at mobile and TV apps (e.g. large touch-friendly controls). Developed by LG Electronix and Apache-licensed on GitHub.

15. The radical Cappuccino - Objective-J (a superset of JavaScript) instead of HTML+CSS+DOM

16. Mochaui, MooTools UI Library User Interface Library. <300 GitHub stars.

17. CrossUI - cross-browser JS framework to develop and package the exactly same code and UI into Web Apps, Native Desktop Apps (Windows, OS X, Linux) and Mobile Apps (iOS, Android, Windows Phone, BlackBerry). Open sourced LGPL3. Featured RAD tool (form builder etc.). The UI looks desktop-, not web-oriented. Actively developed, small community. No presence on GitHub.

18. ZinoUI - simple widgets. The DataTable, for instance, doesn't even support sorting.

19. Wijmo - good-looking commercial widgets, with old (jQuery UI) widgets open-sourced on GitHub (their development stopped in 2013). Developed by ComponentOne, a division of GrapeCity. See Wijmo Complete vs. Open.

20. CxJS - commercial JS framework based on React, Babel and webpack offering form elements, form validation, advanced grid control, navigational elements, tooltips, overlays, charts, routing, layout support, themes, culture dependent formatting and more.

Widgets - Demo Apps - Examples - GitHub

Full-stack frameworks

1. SproutCore - developed by Apple for web applications with native performance, handling large data sets on the client. Powers iCloud.com. Not intended for widgets.

2. Wakanda: aimed at business/enterprise web apps - see What is Wakanda?. Architecture:

   • Wakanda Server (server-side JavaScript (custom engine) + open-source NoSQL database)
   • desktop IDE and WYSIWYG editor for tables, forms, reports

   • Wakanda Application Framework (datasource layer + browser-based interface widgets) that helps with browser and device compatibility across desktop and mobile

     Wakanda is highly integrated, includes a ton of features out of the box, but has a very small GitHub community and SO presence.

3. Servoy - "a cross platform frontend development and deployment environment for SQL databases". Boasts a "full WYSIWIG (What You See Is What You Get) UI designer for HTML5 with built-in data-binding to back-end services", responsive design, support for HTML6 Web Components, Websockets and mobile platforms. Written in Java and generates JavaScript code using various JavaBeans.

4. SmartClient/SmartGWT - mobile and cross-browser HTML5 UI components combined with a Java server. Aimed at building powerful business apps - see demos.

5. Vaadin - full-stack Java/GWT + JavaScript/HTML3 web app framework

6. Backbase - portal software

7. Shiny - front-end library on top R, with visualization, layout and control widgets

8. ZKOSS: Java+jQuery+Bootstrap framework for building enterprise web and mobile apps.

CSS libraries + minimal widgets

These libraries don't implement complex widgets such as tables with sorting/filtering, autocompletes, or trees.

1. Bootstrap

2. Foundation for Apps - responsive front-end framework on top of AngularJS; more of a grid/layout/navigation library

3. UI Kit - similar to Bootstrap, with fewer widgets, but with official off-canvas.

Libraries using HTML Canvas

Using the canvas elements allows for complete control over the UI, and great cross-browser compatibility, but comes at the cost of missing native browser functionality, e.g. page search via Ctrl/Cmd+F.

1. Zebra - demos

No longer developed as of Dec 2014

1. Yahoo! User Interface - YUI, launched in 2005, but no longer maintained by the core contributors - see the announcement, which highlights reasons why large UI widget libraries are perceived as walled gardens that developers don't want to be locked into.
2. echo3, GitHub. Supports writing either server-side Java applications that don't require developer knowledge of HTML, HTTP, or JavaScript, or client-side JavaScript-based applications do not require a server, but can communicate with one via AJAX. Last update: July 2013.

According to this gist, you can use wget or cURL:

1. Click the file name in a GitHub repo.
2. Click Raw to display the file contents.
3. Copy the URL in your browser.

4. In the command line, run either:

   • wget --no-check-certificate --content-disposition https://URL-from-step3/
   • curl -LJO https://URL-from-step3/

   One more: in RHEL7.6, run the following:

   • wget https://URL-from-step3/ --output-document=FILE_NAME

Note that there is no variable interpolation in Java. Variable interpolation is variable substitution with its value inside a string. An example in Ruby:

#!/usr/bin/ruby

age = 34
name = "William"

puts "#{name} is #{age} years old"

The Ruby interpreter automatically replaces variables with its values inside a string. The fact, that we are going to do interpolation is hinted by sigil characters. In Ruby, it is #{}. In Perl, it could be $, % or @. Java would only print such characters, it would not expand them.

Variable interpolation is not supported in Java. Instead of this, we have string formatting.

package com.zetcode;

public class StringFormatting 
{
    public static void main(String[] args) 
    {
        int age = 34;
        String name = "William";

        String output = String.format("%s is %d years old.", name, age);
    
        System.out.println(output);
    }
}

In Java, we build a new string using the String.format() method. The outcome is the same, but the methods are different.

See http://en.wikipedia.org/wiki/Variable_interpolation

Edit As of 2019, JEP 326 (Raw String Literals) was withdrawn and superseded by multiple JEPs eventually leading to JEP 378: Text Blocks delivered in Java 15.

A text block is a multi-line string literal that avoids the need for most escape sequences, automatically formats the string in a predictable way, and gives the developer control over the format when desired.

However, still no string interpolation:

Non-Goals: … Text blocks do not directly support string interpolation. Interpolation may be considered in a future JEP. In the meantime, the new instance method String::formatted aids in situations where interpolation might be desired.

For solving this tasks I usually use the following command:

$ cat file{1..3}.txt >> result.txt

It's a very convenient way to concatenate files if the number of files is quite large.

the main difference between them is just

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

Thankfully(?), in SQL Server 2012+, you can now use FORMAT() to achieve this:

FORMAT(@s,'#,0.0000')

[Query]:

declare @s decimal(18,10);
set @s = 1234.1234567;
select replace(convert(varchar,cast(floor(@s) as money),1),'.00',
    '.'+right(cast(@s * 10000 +10000.5 as int),4))

In the first part, we use MONEY->VARCHAR to produce the commas, but FLOOR() is used to ensure the decimals go to .00. This is easily identifiable and replaced with the 4 digits after the decimal place using a mixture of shifting (*10000) and CAST as INT (truncation) to derive the digits.

[Results]:

|   COLUMN_0 |
--------------
| 1,234.1235 |

But unless you have to deliver business reports using SQL Server Management Studio or SQLCMD, this is NEVER the correct solution, even if it can be done. Any front-end or reporting environment has proper functions to handle display formatting.

To build and install modern Git on CentOS 6:

yum install -y curl-devel expat-devel gettext-devel openssl-devel zlib-devel gcc perl-ExtUtils-MakeMaker
export GIT_VERSION=2.6.4
mkdir /root/git
cd /root/git
wget "https://www.kernel.org/pub/software/scm/git/git-${GIT_VERSION}.tar.gz"
tar xvzf "git-${GIT_VERSION}.tar.gz"
cd git-${GIT_VERSION}
make prefix=/usr/local all
make prefix=/usr/local install
yum remove -y git
git --version # should be GIT_VERSION

This is how I did it.

from selenium import webdriver

chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument('--disable-extensions')

chrome = webdriver.Chrome(chrome_options=chrome_options)

Based on the title of this question, I came here wanting to convert a String into an array of substrings divided by some delimiter. I will add that answer here for others who may have the same question.

This makes an array of words by splitting the string at every space:

String str = "string to string array conversion in java";
String delimiter = " ";
String strArray[] = str.split(delimiter);

This creates the following array:

// [string, to, string, array, conversion, in, java]

I thought the regular modulus operator would work for this in java, but it can't be hard to code. Just divide the numerator by the denominator, and take the integer portion of the result. Multiply that by the denominator, and subtract the result from the numerator.

x = n / d
xint = Integer portion of x
result = n - d * xint
