There are two approaches, you can code in JScript or VBScript which do have the construct or you can fudge it in your code.

Using JScript you'd use the following type of construct:

<script language="jscript" runat="server">
try  {
    tryStatements
}
catch(exception) {
    catchStatements
}
finally {
    finallyStatements
}
</script>

In your ASP code you fudge it by using on error resume next at the point you'd have a try and checking err.Number at the point of a catch like:

<%
' Turn off error Handling
On Error Resume Next


'Code here that you want to catch errors from

' Error Handler
If Err.Number <> 0 Then
   ' Error Occurred - Trap it
   On Error Goto 0 ' Turn error handling back on for errors in your handling block
   ' Code to cope with the error here
End If
On Error Goto 0 ' Reset error handling.

%>

Using generates a try / finally around the object being allocated and calls Dispose() for you.

It saves you the hassle of manually creating the try / finally block and calling Dispose()

Check below example

<script src='https://www.google.com/recaptcha/api.js'></script>
<script>

function get_action(form) 
{
    var v = grecaptcha.getResponse();
    if(v.length == 0)
    {
        document.getElementById('captcha').innerHTML="You can't leave Captcha Code empty";
        return false;
    }
    else
    {
         document.getElementById('captcha').innerHTML="Captcha completed";
        return true; 
    }
}

</script>
<form autocomplete="off" method="post" action=submit.php">

    <input type="text" name="name">
    <input type="text" name="email">
    <div class="g-recaptcha" id="rcaptcha"  data-sitekey="site key"></div>
    <span id="captcha" style="color:red" /></span> <!-- this will show captcha errors -->
    <input type="submit" id="sbtBrn" value="Submit" name="sbt" class="btn btn-info contactBtn" />
</form>

Here are a few options for changing text / label sizes

library(ggplot2)

# Example data using mtcars

a <- aggregate(mpg ~ vs + am , mtcars, function(i) round(mean(i)))

p <- ggplot(mtcars, aes(factor(vs), y=mpg, fill=factor(am))) + 
            geom_bar(stat="identity",position="dodge") + 
            geom_text(data = a, aes(label = mpg), 
                            position = position_dodge(width=0.9),  size=20)

The size in the geom_text changes the size of the geom_text labels.

p <- p + theme(axis.text = element_text(size = 15)) # changes axis labels

p <- p + theme(axis.title = element_text(size = 25)) # change axis titles

p <- p + theme(text = element_text(size = 10)) # this will change all text size 
                                                             # (except geom_text)

For this And why size of 10 in geom_text() is different from that in theme(text=element_text()) ?

Yes, they are different. I did a quick manual check and they appear to be in the ratio of ~ (14/5) for geom_text sizes to theme sizes.

So a horrible fix for uniform sizes is to scale by this ratio

geom.text.size = 7
theme.size = (14/5) * geom.text.size

ggplot(mtcars, aes(factor(vs), y=mpg, fill=factor(am))) + 
  geom_bar(stat="identity",position="dodge") + 
  geom_text(data = a, aes(label = mpg), 
            position = position_dodge(width=0.9),  size=geom.text.size) + 
  theme(axis.text = element_text(size = theme.size, colour="black")) 

This of course doesn't explain why? and is a pita (and i assume there is a more sensible way to do this)

[[ $var =~ ^-?[0-9]+$ ]]

• The ^ indicates the beginning of the input pattern
• The - is a literal "-"
• The ? means "0 or 1 of the preceding (-)"
• The + means "1 or more of the preceding ([0-9])"
• The $ indicates the end of the input pattern

So the regex matches an optional - (for the case of negative numbers), followed by one or more decimal digits.

From my experience with GCC I know that static and static inline differs in a way how compiler issue warnings about unused functions. More precisely when you declare static function and it isn't used in current translation unit then compiler produce warning about unused function, but you can inhibit that warning with changing it to static inline.

Thus I tend to think that static should be used in translation units and benefit from extra check compiler does to find unused functions. And static inline should be used in header files to provide functions that can be in-lined (due to absence of external linkage) without issuing warnings.

Unfortunately I cannot find any evidence for that logic. Even from GCC documentation I wasn't able to conclude that inline inhibits unused function warnings. I'd appreciate if someone will share links to description of that.

StartDate = moment(StartDate).format('MM-YYYY');

...and MySQL date format:

StartDate = moment(StartDate).format('YYYY-MM-DD');

Use expression(delta) where 'delta' for lowercase d and 'Delta' to get capital ?.

Here's full list of Greek characters:

? a alpha
? ß beta
G ? gamma
? d delta
? e epsilon
? ? zeta
? ? eta
T ? theta
? ? iota
? ? kappa
? ? lambda
? µ mu
? ? nu
? ? xi
? ? omicron
? p pi
? ? rho
S s sigma
? t tau
? ? upsilon
F f phi
? ? chi
? ? psi
O ? omega

EDIT: Copied from comments, when using in conjunction with other words use like: expression(Delta*"price")

Another way to work this around is to add this into your module package.json scripts section

"preinstall": "npm install {Packages You depend on}"

what this will does is, it will install all packages needed by the module and you won't get that error.

You just need to:

Step 1: Go home directory of C:\ with typing cd.. (2 times)

Step 2: It appears now C:\>

Step 3: Type dir Windows\System32\run

That's all, it shows complete files & folder details inside target folder.

Details: I used Windows\System32\com folder as example, you should type your own folder name etc. Windows\System32\run

Here's my shot at a more general solution:

UNI: For UNIQUE:

• It is a set of one or more columns of a table to uniquely identify the record.
• A table can have multiple UNIQUE key.
• It is quite like primary key to allow unique values but can accept one null value which primary key does not.

PRI: For PRIMARY:

• It is also a set of one or more columns of a table to uniquely identify the record.
• A table can have only one PRIMARY key.
• It is quite like UNIQUE key to allow unique values but does not allow any null value.

MUL: For MULTIPLE:

• It is also a set of one or more columns of a table which does not identify the record uniquely.
• A table can have more than one MULTIPLE key.
• It can be created in table on index or foreign key adding, it does not allow null value.
• It allows duplicate entries in column.
• If we do not specify MUL column type then it is quite like a normal column but can allow null entries too hence; to restrict such entries we need to specify it.
• If we add indexes on column or add foreign key then automatically MUL key type added.

You can do by the following ways

this.your_form.getRawValue()['formcontrolname]
this.your_form.value['formcontrolname]

Note that you should note that your logic flow must never rely on accessing the HashMap elements in some order, simply put because HashMaps are not ordered Collections and that is not what they are aimed to do. (You can read more about odered and sorter collections in this post).

Back to the post, you already did half the job by loading the first element key:

Object myKey = statusName.keySet().toArray()[0];

Just call map.get(key) to get the respective value:

Object myValue = statusName.get(myKey);

Another option is http://localtunnel.me/ if you're running NodeJS

npm install -g localtunnel

Start a webserver on any local port such as 8080, and create a tunnel to that port:

lt -p 8080

which will return a public URL for your localhost at randomname.localtunnel.me. You can request your own subdomain if it's available:

lt -p 8080 -s myname

which will return myname.localtunnel.me

Based in the answer by WhoIsNinja:

This code will output both into the Console and into a Log string that can be saved into a file, either by appending lines to it or by overwriting it.

The default name for the log file is 'Log.txt' and is saved under the Application path.

public static class Logger
{
    public static StringBuilder LogString = new StringBuilder();
    public static void WriteLine(string str)
    {
        Console.WriteLine(str);
        LogString.Append(str).Append(Environment.NewLine);
    }
    public static void Write(string str)
    {
        Console.Write(str);
        LogString.Append(str);

    }
    public static void SaveLog(bool Append = false, string Path = "./Log.txt")
    {
        if (LogString != null && LogString.Length > 0)
        {
            if (Append)
            {
                using (StreamWriter file = System.IO.File.AppendText(Path))
                {
                    file.Write(LogString.ToString());
                    file.Close();
                    file.Dispose();
                }
            }
            else
            {
                using (System.IO.StreamWriter file = new System.IO.StreamWriter(Path))
                {
                    file.Write(LogString.ToString());
                    file.Close();
                    file.Dispose();
                }
            }               
        }
    }
}

Then you can use it like this:

Logger.WriteLine("==========================================================");
Logger.Write("Loading 'AttendPunch'".PadRight(35, '.'));
Logger.WriteLine("OK.");

Logger.SaveLog(true); //<- default 'false', 'true' Append the log to an existing file.

I faced the same problem too. Look up to the left side, and select (full). (Make), (gcc) and many others will appear. You will be able to chose the search bar to find them easily.

In addition to the RFC Spec you can also see this in action. Check out the twitter responses.

I've just been struggling with MSVC2005 to use the std::string(char*) constructor just like the top-rated answer. As I see this variant listed as #4 on always-trusted http://en.cppreference.com/w/cpp/string/basic_string/basic_string , I figure even an old compiler offers this.

It has taken me so long to realize that this constructor absolute refuses to match with (unsigned char*) as an argument ! I got these incomprehensible error messages about failure to match with std::string argument type, which was definitely not what I was aiming for. Just casting the argument with std::string((char*)ucharPtr) solved my problem... duh !

Any uncomitted transaction will leave the server locked and other queries won't execute on the server. You either need to rollback the transaction or commit it. Closing out of SSMS will also terminate the transaction which will allow other queries to execute.

why don't you store your values in HTML5 storage objects such as sessionStorage or localStorage, visit HTML5 Storage Doc to get more details. Using this you can store intermediate values temporarily/permanently locally and then access your values later.

To store values for a session:

sessionStorage.getItem('label')
sessionStorage.setItem('label', 'value')

or more permanently:

localStorage.getItem('label')
localStorage.setItem('label', 'value')

So you can store (temporarily) form data between multiple pages using HTML5 storage objects which you can even retain after reload..

if you are using nodejs as backend, here are steps to follow

1. install cors in your backend app

   npm install cors

2. Add this code

    const cors = require('cors');
    const express = require('express');
    const expressApp = express();
    expressApp.use(cors({
        origin: ['http://localhost:4200'],
        "methods": "GET,PUT,POST",
        "preflightContinue": false,
        "optionsSuccessStatus": 204,
        credentials: true
    }));
   

You could try something like this.

def main():
    try:
        user_in = int(input("Enter a number to determine whether the number is prime or not: "))
    except ValueError:
        print()
        print("You must enter a number!")
        print()
        return
    list_range = list(range(2,user_in+1))
    divisor_list = []
    for number in list_range:
        if user_in%number==0:
            divisor_list.append(number)
    if len(divisor_list) < 2:
        print(user_in, "is a prime number!")
        return
    else:
        print(user_in, "is not a prime number!")
        return
main()

Just a note for people having the same problem as me. I've been using OpenCV/cv2 to export numpy arrays into Tiffs but I had problems with opening these Tiffs with PIL Open Image and had the same error as in the title. The problem turned out to be that PIL Open Image could not open Tiffs which was created by exporting numpy float64 arrays. When I changed it to float32, PIL could open the Tiff again.

Try this. It almost seemed to simple to be right. Simply convert the Integer to a string. Then you can use the method below or concatenate.

Dim I, J, K, L As Integer
Dim K1, L1 As String

K1 = K
L1 = L
Cells(2, 1) = K1 & " - uploaded"
Cells(3, 1) = L1 & " - expanded"

MsgBox "records uploaded " & K & " records expanded " & L

This answer is based on the question and title of this book: http://www.packtpub.com/angularjs-web-application-development/book

For those like me who come to this page with this problem after updating Xcode but don't have an issue with the location setting, restarting my computer did the trick.

I think you want to specify

-H "Content-Type:text/xml"

with a colon, not an equals.

The ScriptIgnoreAttribute class is in the System.Web.Extensions.dll assembly (Located under Assemblies > Framework in the VS Reference Manager). You have to add a reference to that assembly in your class library project.

You can find this information at top of the MSDN page for the ScriptIgnoreAttribute class.

There are few steps to overcome this problem:

1. Uninstall Java related softwares
2. Uninstall NodeJS if installed
3. Download java 8 update161
4. Install it

The problem solved: The problem raised to me at the uninstallation on openfire server.

you can do

DELETE FROM `mytable` WHERE `id` > 0

ES6 version should be much simplifier (another one line solution)

let arr = [5, 5, 5, 2, 2, 2, 2, 2, 9, 4];
let acc = arr.reduce((acc, val) => acc.set(val, 1 + (acc.get(val) || 0)), new Map());

console.log(acc);
// output: Map { 5 => 3, 2 => 5, 9 => 1, 4 => 1 }

A Map instead of plain Object helping us to distinguish different type of elements, or else all counting are base on strings

Your question feels a little incomplete, but I think what you're looking for is a way of making your JSON accessible to your code:

if you have the JSON string as above then you'd just need to do this

var jsonObj = eval('[{"id":28,"Title":"Sweden"}, {"id":56,"Title":"USA"}, {"id":89,"Title":"England"}]');

then you can access these vars with something like jsonObj[0].id etc

Let me know if that's not what you were getting at and I'll try to help.

Use the example of Syed Raza Mehdi and add on the Application theme the name=actionOverflowButtonStyle parameter for compatibility.

<!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
    <!-- All customizations that are NOT specific to a particular API-level can go here. -->
    <item name="android:actionOverflowButtonStyle">@style/MyActionButtonOverflow</item>

    <!-- For compatibility -->
    <item name="actionOverflowButtonStyle">@style/MyActionButtonOverflow</item>

</style>

If you are using the InternetExplorer.Application COM object, check the ReadyState property for the value of 4.

You can write DateTime? newdate = null;

as noted earlier, setting bash variables does not allow whitespace between the variable name on the LHS, and the variable value on the RHS, of the '=' sign.

awk can do everything and avoid the "awk"ward extra 'grep'. The use of awk's printf is to not add an unnecessary "\n" in the string which would give perl-ish matcher programs conniptions. The variable/parameter expansion for your case in bash doesn't have that issue, so either of these work:

variable=$(ps -ef | awk '/port 10 \-/ {print $12}')

variable=`ps -ef | awk '/port 10 \-/ {print $12}'`

The '-' int the awk record matching pattern removes the need to remove awk itself from the search results.

Here's some full and simple code to do this. This worked fine when I used it.

var processStartInfo = new ProcessStartInfo
{
    FileName = @"C:\SomeProgram",
    Arguments = "Arguments",
    RedirectStandardOutput = true,
    UseShellExecute = false
};
var process = Process.Start(processStartInfo);
var output = process.StandardOutput.ReadToEnd();
process.WaitForExit();

Note that this only captures standard output; it doesn't capture standard error. If you want both, use this technique for each stream.

The instruction has been tested on Mac OSx Catalina.

After installing Sublime Text 3, install Package Control through Tools > Package Control. Use the following instructions to install package or theme:

1. press CMD + SHIFT + P

2. choose Package Control: Install Package---or any other options you require.

3. enter the name of required package or theme and press enter.

You should also be aware that the behaviour of postincrement/decrement operators is different in C/C++ and Java.

Given

  int a=1;

in C/C++ the expression

 a++ + a++ + a++

evaluates to 3, while in Java it evaluates to 6. Guess why...

This example is even more confusing:

cout << a++ + a++ + a++ << "<->" << a++ + a++ ;

prints 9<->2 !! This is because the above expression is equivalent to:

operator<<( 
  operator<<( 
    operator<<( cout, a++ + a++ ), 
    "<->"
  ), 
  a++ + a++ + a++ 
)

For how to do it in jQuery:

<select id="yourid">
<option value="Value 1">Text 1</option>
<option value="Value 2">Text 2</option>
</select>

<script src="jquery.js"></script>
<script>
$('#yourid').change(function() {
  alert('The option with value ' + $(this).val() + ' and text ' + $(this).text() + ' was selected.');
});
</script>

You should also know that Javascript and jQuery are not identical. jQuery is valid JavaScript code, but not all JavaScript is jQuery. You should look up the differences and make sure you are using the appropriate one.

Exactly how to do this depends on the version of Jackson that you're using. This changed around version 1.9, before that, you could do this by adding @JsonIgnore to the getter.

Which you've tried:

Add @JsonIgnore on the getter method only

Do this, and also add a specific @JsonProperty annotation for your JSON "password" field name to the setter method for the password on your object.

More recent versions of Jackson have added READ_ONLY and WRITE_ONLY annotation arguments for JsonProperty. So you could also do something like:

@JsonProperty(access = Access.WRITE_ONLY)
private String password;

Docs can be found here.

I would prefer the C++ size constraints over the C versions:

// Ignore to the end of file
cin.ignore(std::numeric_limits<std::streamsize>::max())

// Ignore to the end of line
cin.ignore(std::numeric_limits<std::streamsize>::max(), '\n')

Have you tried using dictionary comprehension with dictionary mapping:

a = {'a': 1, 'b': 2}
b = {'c': 3, 'd': 4}

c = {**a, **b}
# c = {"a": 1, "b": 2, "c": 3, "d": 4}

Another way of doing is by Using dict(iterable, **kwarg)

c = dict(a, **b)
# c = {'a': 1, 'b': 2, 'c': 3, 'd': 4}

In Python 3.9 you can add two dict using union | operator

# use the merging operator |
c = a | b
# c = {'a': 1, 'b': 2, 'c': 3, 'd': 4}

Option a)

If you want to ensure keyboard events are fired, consider using sendKeys(CharSequence).

Example 1:

 from selenium.webdriver.common.keys import Keys
 # ...
 webElement.sendKeys(Keys.CONTROL + "a");
 webElement.sendKeys(Keys.DELETE);

Example 2:

 from selenium.webdriver.common.keys import Keys
 # ...
 webElement.sendKeys(Keys.BACK_SPACE); //do repeatedly, e.g. in while loop

WebElement

There are many ways to get the required WebElement, e.g.:

• driver.find_element_by_id
• driver.find_element_by_xpath
• driver.find_element

Option b)

 webElement.clear();

If this element is a text entry element, this will clear the value.

Note that the events fired by this event may not be as you'd expect. In particular, we don't fire any keyboard or mouse events.

For Ubuntu,

python -c "from distutils.sysconfig import get_python_lib; print get_python_lib()"

...is not correct.

It will point you to /usr/lib/pythonX.X/dist-packages

This folder only contains packages your operating system has automatically installed for programs to run.

On ubuntu, the site-packages folder that contains packages installed via setup_tools\easy_install\pip will be in /usr/local/lib/pythonX.X/dist-packages

The second folder is probably the more useful one if the use case is related to installation or reading source code.

If you do not use Ubuntu, you are probably safe copy-pasting the first code box into the terminal.

This is easier and gives purpose to the never used unordered/ordered list tags.

In your CSS add:

    li{float: left;}  //Sets float left property globally for all li tags.

Then add in your HTML:

    <ul>
         <li>1</li>
         <li>2</li>
         <li>3</li>        
    </ul>

Now watch it all line up perfectly! No more arguing over tables vs divs!

I had the same problem, all you need to do is define classpath environment variable for tomcat, you can do it by adding a file, in my case C:\apache-tomcat-7.0.30\bin\setenv.bat, containing:

set "CLASSPATH=%CLASSPATH%;%CATALINA_HOME%\lib\mysql-connector-java-5.1.14-bin.jar"

then code, in my case:

Class.forName("com.mysql.jdbc.Driver").newInstance(); 
conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/database_name", "root", "");

works fine.

I had the same issue, I cleaned and rebuilt the project and it worked.

I had a similar issue using like pattern '%_%' did not work - as the question indicates :-)

Using '%\_%' did not work either as this first \ is interpreted "before the like".

Using '%\\_%' works. The \\ (double backslash) is first converted to single \ (backslash) and then used in the like pattern.

table

We have Teacher table

Oracle Syntax

SELECT * FROM   
(
SELECT column_name FROM table_name  
ORDER BY dbms_random.value
)  
WHERE rownum = 1;

For better understanding follow screenshot

It's simple-

SELECT empname,
       empid,
       (SELECT COUNT (profileid)
          FROM profile
         WHERE profile.empid = employee.empid)
           AS number_of_profiles
  FROM employee;

It is even simpler when you use a table join like this:

  SELECT e.empname, e.empid, COUNT (p.profileid) AS number_of_profiles
    FROM employee e LEFT JOIN profile p ON e.empid = p.empid
GROUP BY e.empname, e.empid;

Explanation for the subquery:

Essentially, a subquery in a select gets a scalar value and passes it to the main query. A subquery in select is not allowed to pass more than one row and more than one column, which is a restriction. Here, we are passing a count to the main query, which, as we know, would always be only a number- a scalar value. If a value is not found, the subquery returns null to the main query. Moreover, a subquery can access columns from the from clause of the main query, as shown in my query where employee.empid is passed from the outer query to the inner query.

Edit:

When you use a subquery in a select clause, Oracle essentially treats it as a left join (you can see this in the explain plan for your query), with the cardinality of the rows being just one on the right for every row in the left.

Explanation for the left join

A left join is very handy, especially when you want to replace the select subquery due to its restrictions. There are no restrictions here on the number of rows of the tables in either side of the LEFT JOIN keyword.

For more information read Oracle Docs on subqueries and left join or left outer join.

Assuming your page is available under "http://example.com"

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Firefox()
driver.get("http://example.com")

Select element by id:

inputElement = driver.find_element_by_id("a1")
inputElement.send_keys('1')

Now you can simulate hitting ENTER:

inputElement.send_keys(Keys.ENTER)

or if it is a form you can submit:

inputElement.submit() 

To let MySql generate sequence numbers for an AUTO_INCREMENT field you have three options:

1. specify list a column list and omit your auto_incremented column from it as njk suggested. That would be the best approach. See comments.
2. explicitly assign NULL
3. explicitly assign 0

3.6.9. Using AUTO_INCREMENT:

...No value was specified for the AUTO_INCREMENT column, so MySQL assigned sequence numbers automatically. You can also explicitly assign NULL or 0 to the column to generate sequence numbers.

These three statements will produce the same result:

$insertQuery = "INSERT INTO workorders (`priority`, `request_type`) VALUES('$priority', '$requestType', ...)";
$insertQuery = "INSERT INTO workorders VALUES(NULL, '$priority', ...)";
$insertQuery = "INSERT INTO workorders VALUES(0, '$priority', ...";

Based on what I have tested this is my proposal

I error occor. When you are trying to access a file which is not in the director. Carefully check path in the view

 $this->load->view('path');

default root path of view function is application/view .

I had the same error. I was trying to access files like this

 $this->load->view('pages/view/file.php');

Actually I have the class Pages and function. I built the function with one argument to call the any files from the director application/view/pages . I was put the wrong path. The above path pages/view/files can be used when you are trying to access the controller. Not for the view. MVC gave a lot confusion. I had this problem. I just solve it. Thanks.

About this I think you can reference to http://docs.oasis-open.org/security/saml/Post2.0/sstc-saml-tech-overview-2.0.html.

Here're my understandings about this, with the Identity Federation Use Case to give a details for those concepts:

• Persistent identifiers-

IdP provides the Persistent identifiers, they are used for linking to the local accounts in SPs, but they identify as the user profile for the specific service each alone. For example, the persistent identifiers are kind of like : johnForAir, jonhForCar, johnForHotel, they all just for one specified service, since it need to link to its local identity in the service.

• Transient identifiers-

Transient identifiers are what IdP tell the SP that the users in the session have been granted to access the resource on SP, but the identities of users do not offer to SP actually. For example, The assertion just like “Anonymity(Idp doesn’t tell SP who he is) has the permission to access /resource on SP”. SP got it and let browser to access it, but still don’t know Anonymity' real name.

• unspecified identifiers-

The explanation for it in the spec is "The interpretation of the content of the element is left to individual implementations". Which means IdP defines the real format for it, and it assumes that SP knows how to parse the format data respond from IdP. For example, IdP gives a format data "UserName=XXXXX Country=US", SP get the assertion, and can parse it and extract the UserName is "XXXXX".

It helps to trace the exception. For example you are writing some methods in your program and one of your methods causes bug. Then printstack will help you to identify which method causes the bug. Stack will help like this:

First your main method will be called and inserted to stack, then the second method will be called and inserted to the stack in LIFO order and if any error occurs somewhere inside any method then this stack will help to identify that method.

UTF-8 is a variable-length encoding. In the case of UTF-8, this means that storing one code point requires one to four bytes. However, MySQL's encoding called "utf8" (alias of "utf8mb3") only stores a maximum of three bytes per code point.

So the character set "utf8"/"utf8mb3" cannot store all Unicode code points: it only supports the range 0x000 to 0xFFFF, which is called the "Basic Multilingual Plane". See also Comparison of Unicode encodings.

This is what (a previous version of the same page at) the MySQL documentation has to say about it:

The character set named utf8[/utf8mb3] uses a maximum of three bytes per character and contains only BMP characters. As of MySQL 5.5.3, the utf8mb4 character set uses a maximum of four bytes per character supports supplemental characters:

• For a BMP character, utf8[/utf8mb3] and utf8mb4 have identical storage characteristics: same code values, same encoding, same length.

• For a supplementary character, utf8[/utf8mb3] cannot store the character at all, while utf8mb4 requires four bytes to store it. Since utf8[/utf8mb3] cannot store the character at all, you do not have any supplementary characters in utf8[/utf8mb3] columns and you need not worry about converting characters or losing data when upgrading utf8[/utf8mb3] data from older versions of MySQL.

So if you want your column to support storing characters lying outside the BMP (and you usually want to), such as emoji, use "utf8mb4". See also What are the most common non-BMP Unicode characters in actual use?.

You can use Mockito.isA() for that:

import static org.mockito.Mockito.verify;

verify(bar).doStuff(isA(Foo[].class));

I confirm that git and msysgit can coexist on the same computer, as mentioned in "Which GIT version to use cygwin or msysGit or both?".

1. Git for Windows (msysgit) will run in its own shell (dos with git-cmd.bat or bash with Git Bash.vbs)
   Update 2016: msysgit is obsolete, and the new Git for Windows now uses msys2

2. Git on Cygwin, after installing its package, will run in its own cygwin bash shell.

3. Finally, since Q3 2016 and the "Windows 10 anniversary update", you can use Git in a bash (an actual Ubuntu(!) bash).

In there, you can do a sudo apt-get install git-core and start using git on project-sources present either on the WSL container's "native" file-system (see below), or in the hosting Windows's file-system through the /mnt/c/..., /mnt/d/... directory hierarchies.

Specifically for the Bash on Windows or WSL (Windows Subsystem for Linux):

• It is a light-weight virtualization container (technically, a "Drawbridge" pico-process,
• hosting an unmodified "headless" Linux distribution (i.e. Ubuntu minus the kernel),
• which can execute terminal-based commands (and even X-server client apps if an X-server for Windows is installed),
• with emulated access to the Windows file-system (meaning that, apart from reduced performance, encodings for files in DrvFs emulated file-system may not behave the same as files on the native VolFs file-system).

• Unfortunately, it cannot invoke back into Windows executables, or
• interact with any native drivers (i.e. so no Graphic card, no USB drives yet).

The overwrite function equals() is wrong. The object "a" is an instance of the String class and "object2" is an instance of the MyClass class. They are different classes, so the answer is "false".

I had the same problem. It was because I had accidentally used a relative path with the symbolic link.

Are you sure you used full paths, e.g.:

ln -s /etc/nginx/sites-available/example.com.conf /etc/nginx/sites-enabled/example.com.conf

Even if the question is old, a more accurate answer about Management Studio would be required.

You can create the column manually or with Management Studio. But Management Studio will require to recreate the table and will result in a time out if you have too much data in it already, avoid unless the table is light.

To change the order of the columns you simply need to move them around in Management Studio. This should not require (Exceptions most likely exists) that Management Studio to recreate the table since it most likely change the ordination of the columns in the table definitions.

I've done it this way on numerous occasion with tables that I could not add columns with the GUI because of the data in them. Then moved the columns around with the GUI of Management Studio and simply saved them.

You will go from an assured time out to a few seconds of waiting.

If I read the specs right then let thankfully can also be leveraged to avoid self invoking functions used to simulate private only members - a popular design pattern that decreases code readability, complicates debugging, that adds no real code protection or other benefit - except maybe satisfying someone's desire for semantics, so stop using it. /rant

var SomeConstructor;

{
    let privateScope = {};

    SomeConstructor = function SomeConstructor () {
        this.someProperty = "foo";
        privateScope.hiddenProperty = "bar";
    }

    SomeConstructor.prototype.showPublic = function () {
        console.log(this.someProperty); // foo
    }

    SomeConstructor.prototype.showPrivate = function () {
        console.log(privateScope.hiddenProperty); // bar
    }

}

var myInstance = new SomeConstructor();

myInstance.showPublic();
myInstance.showPrivate();

console.log(privateScope.hiddenProperty); // error

See 'Emulating private interfaces'

Additionally, if you don't want it to ask for a passphrase, then need to run the following command:

openssl rsa -in server.key -out server.key

Your __init__.py should have a docstring.

Although all the functionality is implemented in modules and subpackages, your package docstring is the place to document where to start. For example, consider the python email package. The package documentation is an introduction describing the purpose, background, and how the various components within the package work together. If you automatically generate documentation from docstrings using sphinx or another package, the package docstring is exactly the right place to describe such an introduction.

For any other content, see the excellent answers by firecrow and Alex Martelli.

for standard make you can pass arguments by defining macros like this

make run arg1=asdf

then use them like this

run: ./prog $(arg1)
   etc

References for make Microsoft's NMake

list.ToArray()

Will do the tric. See here for details.

<VirtualHost *:80>
  DocumentRoot /var/www/app1
  ServerName app1.example.com
</VirtualHost>

<VirtualHost *:80>
  DocumentRoot /var/www/example
  ServerName example.com
</VirtualHost>

<VirtualHost *:80>
  DocumentRoot /var/www/wildcard
  ServerName other.example.com
  ServerAlias *.example.com
</VirtualHost>

Should work. The first entry will become the default if you don't get an explicit match. So if you had app.otherexample.com point to it, it would be caught be app1.example.com.

I try this same method, but with a different list with more values in the function map. My problem was to forget a return statement. This is very important :)

 bottom: new TabBar(
      controller: _controller,
      isScrollable: true,
      tabs:
        moviesTitles.map((title) { return Tab(text: title)}).toList()
      ,
    ),

I had the same problem and it was because PowerShell was not updated. Sometimes Windows preserve version 2.* and I had to manually download and install version 3. After that problem solved and I could use virtual environments very well.

Quick and dirty fix

class MyData:
    def __init__(string=None,list=None):
        if string is not None:
            #do stuff
        elif list is not None:
            #do other stuff
        else:
            #make data empty

Then you can call it with

MyData(astring)
MyData(None, alist)
MyData()

You could use ApexSQL Propagate. It is a free tool which executes multiple scripts on multiple databases. You can select as many scripts as you need and execute them against one or multiple databases (even multiple servers). You can create scripts list and save it, then just select that list each time you want to execute those same scripts in the created order (multiple script lists can be added also):

When scripts and databases are selected, they will be shown in the main window and all you have to do is to click the “Execute” button and all scripts will be executed on selected databases in the given order:

There is something wrong with your design. Try to make your classes represent real world things. For example:

• The class Card should represent one card, that is the nature of a "Card". The Card class does not need to know about Decks.
• The Deck class should contain 52 Card objects (plus jokers?).

you can create and initialize array of any object like this.

hero:Hero[]=[];

Here's a way that I consider easier: The general idea is that you want to append a text element to a circle element then play around with its "dx" and "dy" attributes until you position the text at the point in the circle that you like. In my example, I used a negative number for the dx since I wanted to have text start towards the left of the centre.

const nodes = [ {id: ABC, group: 1, level: 1}, {id:XYZ, group: 2, level: 1}, ]

const nodeElems = svg.append('g')
.selectAll('circle')
.data(nodes)
.enter().append('circle')
.attr('r',radius)
.attr('fill', getNodeColor)

const textElems = svg.append('g')
.selectAll('text')
.data(nodes)
.enter().append('text')
.text(node => node.label)
.attr('font-size',8)//font size
.attr('dx', -10)//positions text towards the left of the center of the circle
.attr('dy',4)

With the new iframe tag embedded in your website, the code will automatically detect whether you are using a browser that supports HTML5 or not.

The iframe code for embedding YouTube videos is as follows, simply copy the Video ID and replace in the code below:

<iframe type="text/html" 
    width="640" 
    height="385" 
    src="http://www.youtube.com/embed/VIDEO_ID"
    frameborder="0">
</iframe>

Use file. Examples:

> file --mime-type image.png
image.png: image/png

> file -b --mime-type image.png
image/png

> file -i FILE_NAME
image.png: image/png; charset=binary

You have your ssh clone statement wrong: git clone username [email protected]:root/test.git

That statement would try to clone a repository named username into the location relative to your current path, [email protected]:root/test.git.

You want to leave out username:

git clone [email protected]:root/test.git

Only throw an exception if it is truly an error. If it is expected behavior for the object to not exist, return the null.

Otherwise it is a matter of preference.

You could use an onclick event handler in order to get the input value for the text field. Make sure you give the field an unique id attribute so you can refer to it safely through document.getElementById():

If you want to dynamically add elements, you should have a container where to place them. For instance, a <div id="container">. Create new elements by means of document.createElement(), and use appendChild() to append each of them to the container. You might be interested in outputting a meaningful name attribute (e.g. name="member"+i for each of the dynamically generated <input>s if they are to be submitted in a form.

Notice you could also create <br/> elements with document.createElement('br'). If you want to just output some text, you can use document.createTextNode() instead.

Also, if you want to clear the container every time it is about to be populated, you could use hasChildNodes() and removeChild() together.

<html>
<head>
    <script type='text/javascript'>
        function addFields(){
            // Number of inputs to create
            var number = document.getElementById("member").value;
            // Container <div> where dynamic content will be placed
            var container = document.getElementById("container");
            // Clear previous contents of the container
            while (container.hasChildNodes()) {
                container.removeChild(container.lastChild);
            }
            for (i=0;i<number;i++){
                // Append a node with a random text
                container.appendChild(document.createTextNode("Member " + (i+1)));
                // Create an <input> element, set its type and name attributes
                var input = document.createElement("input");
                input.type = "text";
                input.name = "member" + i;
                container.appendChild(input);
                // Append a line break 
                container.appendChild(document.createElement("br"));
            }
        }
    </script>
</head>
<body>
    <input type="text" id="member" name="member" value="">Number of members: (max. 10)<br />
    <a href="#" id="filldetails" onclick="addFields()">Fill Details</a>
    <div id="container"/>
</body>
</html>

       datename(YEAR,GETDATE()) as 'yourcolumnname'

Yes, reading the User-Agent header will do the trick.

There are some lists out there of known mobile user agents so you don't need to start from scratch. What I did when I had to is to build a database of known user agents and store unknowns as they are detected for revision and then manually figure out what they are. This last thing might be overkill in some cases.

If you want to do it at Apache level, you can create a script which periodically generates a set of rewrite rules checking the user agent (or just once and forget about new user agents, or once a month, whatever suits your case), like

RewriteEngine On

RewriteCond %{HTTP_USER_AGENT} (OneMobileUserAgent|AnotherMobileUserAgent|...)
RewriteRule (.*) mobile/$1

which would move, for example, requests to http://domain/index.html to http://domain/mobile/index.html

If you don't like the approach of having a script recreate a htaccess file periodically, you can write a module which checks the User Agent (I didn't find one already made, but found this particularly appropriate example) and get the user agents from some sites to update them. Then you can complicate the approach as much as you want, but I think in your case the previous approach would be fine.

Seems like the second column is set as a unique index. If you dont need that remove it and your errors will go away. Possibly you added the index by mistake and thats why you are seeing the errors today and werent seeing them yesterday

So, I use IntelliJ for my Android project, and the following solved the issue in the IDE:

just cause it might save someone the few hours I wasted... IntelliJ -> Preferences -> Build, Execution, Deployment -> Build tools -> Maven -> Gradle

and set Gradle JVM to 1.8 make sure you also have JDK 8 installed...

NOTE: the project was compiling just fine from the command line

<span style="padding-left:68px;"></span>

You can also use:

padding-left
padding-right
padding-top
padding-bottom

For me, it was because I had deleted the hidden .git folder.

I fixed it by deleting the folder, re-cloning, and re-making the changes.

I'm confused by your question, seems to me that the question title and body are asking different things. If you want to disable/enable a click event on a div simply do:

$("#id").on('click', function(){ //enables click event
    //do your thing here
});

$("#id").off('click'); //disables click event

If you want to disable a div, use the following code:

$("#id").attr('disabled','disabled');

Hope this helps.

edit: oops, didn't see the other bind/unbind answer. Sorry. Those methods are also correct, though they've been deprecated in jQuery 1.7, and replaced by on()/off()

Well, you have some options.

You could configure sudo to not prompt for a password. This is not recommended, due to the security risks.

You could write an expect script to read the password and supply it to sudo when required, but that's clunky and fragile.

I would recommend designing the script to run as root and drop its privileges whenever they're not needed. Simply have it sudo -u someotheruser command for the commands that don't require root.

(If they have to run specifically as the user invoking the script, then you could have the script save the uid and invoke a second script via sudo with the id as an argument, so it knows who to su to..)

2021 Update...

Bootstrap 5 (beta)

For aligning within a flexbox div or row...

• ml-auto is now ms-auto
• mr-auto is now me-auto

Bootstrap 4+

• pull-right is now float-right
• text-right is the same as 3.x, and works for inline elements
• both float-* and text-* are responsive for different alignment at different widths (ie: float-sm-right)

The flexbox utils (eg:justify-content-between) can also be used for alignment:

<div class="d-flex justify-content-between">
      <div>
         left
      </div>
      <div>
         right

I started using the 'prefix-free' Script available at http://leaverou.github.io/prefixfree so I don't have to take care about the vendor prefixes. It neatly takes care of setting the correct vendor prefix behind the scenes for you. Plus a jQuery Plugin is available as well so one can still use jQuery's .css() method without code changes, so the suggested line in combination with prefix-free would be all you need:

$('.user-text').css('transform', 'scale(' + ui.value + ')');

// The below C++ function checks for a palindrome and 
// returns true if it is a palindrome and returns false otherwise

bool checkPalindrome ( string s )
{
    // This calculates the length of the string

    int n = s.length();

    // the for loop iterates until the first half of the string
    // and checks first element with the last element,
    // second element with second last element and so on.
    // if those two characters are not same, hence we return false because
    // this string is not a palindrome 

    for ( int i = 0; i <= n/2; i++ ) 
    {
        if ( s[i] != s[n-1-i] )
            return false;
    }
    
    // if the above for loop executes completely , 
    // this implies that the string is palindrome, 
    // hence we return true and exit

    return true;
}

Yes - their performance characteristics differ significantly. It would probably be better to call them SortedList and SortedTree as that reflects the implementation more closely.

Look at the MSDN docs for each of them (SortedList, SortedDictionary) for details of the performance for different operations in different situtations. Here's a nice summary (from the SortedDictionary docs):

The SortedDictionary<TKey, TValue> generic class is a binary search tree with O(log n) retrieval, where n is the number of elements in the dictionary. In this, it is similar to the SortedList<TKey, TValue> generic class. The two classes have similar object models, and both have O(log n) retrieval. Where the two classes differ is in memory use and speed of insertion and removal:

• SortedList<TKey, TValue> uses less memory than SortedDictionary<TKey, TValue>.

• SortedDictionary<TKey, TValue> has faster insertion and removal operations for unsorted data, O(log n) as opposed to O(n) for SortedList<TKey, TValue>.

• If the list is populated all at once from sorted data, SortedList<TKey, TValue> is faster than SortedDictionary<TKey, TValue>.

(SortedList actually maintains a sorted array, rather than using a tree. It still uses binary search to find elements.)

As far as i know, there is no if/then/else in css. Alternatively, you can use javascript function to alter the background-position property of an element.

Don't look too far.

If you develop with ASP.NET MVC, you simply have the user as a property of the Controller class. So in case you get lost in some models looking for the current user, try to step back and to get the relevant information in the controller.

In the controller, just use:

using Microsoft.AspNet.Identity;

  ...

  var userId = User.Identity.GetUserId();
  ...

with userId as a string.

I don't have gnome-terminal installed but you should be able to do this by using a DBUS call on the command-line using dbus-send.

It would be more efficient:

@session_start();

Best,

Thanks to @the-tin-man for putting together the benchmarks!

Alas, I don't really like any of those solutions. Either they require an extra step to get the result ([0] = '', .strip!) or they aren't very semantic/clear about what's happening ([1..-1]: "Um, a range from 1 to negative 1? Yearg?"), or they are slow or lengthy to write out (.gsub, .length).

What we are attempting is a 'shift' (in Array parlance), but returning the remaining characters, rather than what was shifted off. Let's use our Ruby to make this possible with strings! We can use the speedy bracket operation, but give it a good name, and take an arg to specify how much we want to chomp off the front:

class String
  def eat!(how_many = 1)
    self.replace self[how_many..-1]
  end
end

But there is more we can do with that speedy-but-unwieldy bracket operation. While we are at it, for completeness, let's write a #shift and #first for String (why should Array have all the fun??), taking an arg to specify how many characters we want to remove from the beginning:

class String
  def first(how_many = 1)
    self[0...how_many]
  end

  def shift(how_many = 1)
    shifted = first(how_many)
    self.replace self[how_many..-1]
    shifted
  end
  alias_method :shift!, :shift
end

Ok, now we have a good clear way of pulling characters off the front of a string, with a method that is consistent with Array#first and Array#shift (which really should be a bang method??). And we can easily get the modified string as well with #eat!. Hm, should we share our new eat!ing power with Array? Why not!

class Array
  def eat!(how_many = 1)
    self.replace self[how_many..-1]
  end
end

Now we can:

> str = "[12,23,987,43" #=> "[12,23,987,43"
> str.eat!              #=> "12,23,987,43"
> str                   #=> "12,23,987,43"

> str.eat!(3)           #=> "23,987,43"
> str                   #=> "23,987,43"

> str.first(2)          #=> "23"
> str                   #=> "23,987,43"

> str.shift!(3)         #=> "23,"
> str                   #=> "987,43"

> arr = [1,2,3,4,5]     #=> [1, 2, 3, 4, 5] 
> arr.eat!              #=> [2, 3, 4, 5] 
> arr                   #=> [2, 3, 4, 5] 

That's better!

You can try this.

func convertToJSONString(value: AnyObject) -> String? {
        if JSONSerialization.isValidJSONObject(value) {
            do{
                let data = try JSONSerialization.data(withJSONObject: value, options: [])
                if let string = NSString(data: data, encoding: String.Encoding.utf8.rawValue) {
                    return string as String
                }
            }catch{
            }
        }
        return nil
    }

Paul A is right about why the discrepancy exists but the solution offered by Ngm is wrong (in the sense of JQuery).

The equivalent of clientHeight and clientWidth in jquery (1.3) is

$(window).width(), $(window).height()

The main issue with your example that you can't implicitly convert Task<T> return types to the base T type. You need to use the Task.Result property. Note that Task.Result will block async code, and should be used carefully.

Try this instead:

public List<int> TestGetMethod()  
{  
    return GetIdList().Result;  
}

The function scipy.signal.find_peaks, as its name suggests, is useful for this. But it's important to understand well its parameters width, threshold, distance and above all prominence to get a good peak extraction.

According to my tests and the documentation, the concept of prominence is "the useful concept" to keep the good peaks, and discard the noisy peaks.

What is (topographic) prominence? It is "the minimum height necessary to descend to get from the summit to any higher terrain", as it can be seen here:

The idea is:

The higher the prominence, the more "important" the peak is.

Test:

I used a (noisy) frequency-varying sinusoid on purpose because it shows many difficulties. We can see that the width parameter is not very useful here because if you set a minimum width too high, then it won't be able to track very close peaks in the high frequency part. If you set width too low, you would have many unwanted peaks in the left part of the signal. Same problem with distance. threshold only compares with the direct neighbours, which is not useful here. prominence is the one that gives the best solution. Note that you can combine many of these parameters!

Code:

import numpy as np
import matplotlib.pyplot as plt 
from scipy.signal import find_peaks

x = np.sin(2*np.pi*(2**np.linspace(2,10,1000))*np.arange(1000)/48000) + np.random.normal(0, 1, 1000) * 0.15
peaks, _ = find_peaks(x, distance=20)
peaks2, _ = find_peaks(x, prominence=1)      # BEST!
peaks3, _ = find_peaks(x, width=20)
peaks4, _ = find_peaks(x, threshold=0.4)     # Required vertical distance to its direct neighbouring samples, pretty useless
plt.subplot(2, 2, 1)
plt.plot(peaks, x[peaks], "xr"); plt.plot(x); plt.legend(['distance'])
plt.subplot(2, 2, 2)
plt.plot(peaks2, x[peaks2], "ob"); plt.plot(x); plt.legend(['prominence'])
plt.subplot(2, 2, 3)
plt.plot(peaks3, x[peaks3], "vg"); plt.plot(x); plt.legend(['width'])
plt.subplot(2, 2, 4)
plt.plot(peaks4, x[peaks4], "xk"); plt.plot(x); plt.legend(['threshold'])
plt.show()

I follow two simple rules that avoid the vast majority of problems:

1. All headers (and indeed any source files) should include what they need. They should not rely on their users including things.
2. As an adjunct, all headers should have include guards so that they don't get included multiple times by over-ambitious application of rule 1 above.

I also follow the guidelines of:

1. Include system headers first (stdio.h, etc) with a dividing line.
2. Group them logically.

In other words:

#include <stdio.h>
#include <string.h>

#include "btree.h"
#include "collect_hash.h"
#include "collect_arraylist.h"
#include "globals.h"

Although, being guidelines, that's a subjective thing. The rules on the other hand, I enforce rigidly, even to the point of providing 'wrapper' header files with include guards and grouped includes if some obnoxious third-party developer doesn't subscribe to my vision :-)

jQuery.Deferred() can simplify management of asynchronous sequencing and error handling.

polling_active = true // set false to interrupt polling

function initiate_polling()
    {
    $.Deferred().resolve() // optional boilerplate providing the initial 'then()'
    .then( () => $.Deferred( d=>setTimeout(()=>d.resolve(),5000) ) ) // sleep
    .then( () => $.get('/my-api') ) // initiate AJAX
    .then( response =>
        {
        if ( JSON.parse(response).my_result == my_target ) polling_active = false
        if ( ...unhappy... ) return $.Deferred().reject("unhappy") // abort
        if ( polling_active ) initiate_polling() // iterative recursion
        })
    .fail( r => { polling_active=false, alert('failed: '+r) } ) // report errors
    }

This is an elegant approach, but there are some gotchas...

• If you don't want a then() to fall through immediately, the callback should return another thenable object (probably another Deferred), which the sleep and ajax lines both do.
• The others are too embarrassing to admit. :)

Principled Design of the Modern Web Architecture by Roy T. Fielding and Richard N. Taylor, i.e. sequence of works from all REST terminology came from, contains definition of client-server interaction:

All REST interactions are stateless. That is, each request contains all of the information necessary for a connector to understand the request, independent of any requests that may have preceded it.

This restriction accomplishes four functions, 1st and 3rd are important in this particular case:

• 1st: it removes any need for the connectors to retain application state between requests, thus reducing consumption of physical resources and improving scalability;
• 3rd: it allows an intermediary to view and understand a request in isolation, which may be necessary when services are dynamically rearranged;

And now lets go back to your security case. Every single request should contains all required information, and authorization/authentication is not an exception. How to achieve this? Literally send all required information over wires with every request.

One of examples how to archeive this is hash-based message authentication code or HMAC. In practice this means adding a hash code of current message to every request. Hash code calculated by cryptographic hash function in combination with a secret cryptographic key. Cryptographic hash function is either predefined or part of code-on-demand REST conception (for example JavaScript). Secret cryptographic key should be provided by server to client as resource, and client uses it to calculate hash code for every request.

There are a lot of examples of HMAC implementations, but I'd like you to pay attention to the following three:

• Authenticating REST Requests for Amazon Simple Storage Service (Amazon S3)
• Answer by Mauriceless on quiestion: "How to implement HMAC Authentication in a RESTful WCF API"
• crypto-js: JavaScript implementations of standard and secure cryptographic algorithms

How it works in practice

If client knows the secret key, then it's ready to operate with resources. Otherwise he will be temporarily redirected (status code 307 Temporary Redirect) to authorize and to get secret key, and then redirected back to the original resource. In this case there is no need to know beforehand (i.e. hardcode somewhere) what the URL to authorize the client is, and it possible to adjust this schema with time.

Hope this will helps you to find the proper solution!

Clickatell is a popular SMS gateway. It works in 200+ countries.

Their API offers a choice of connection options via: HTTP/S, SMPP, SMTP, FTP, XML, SOAP. Any of these options can be used from php.

The HTTP/S method is as simple as this:

http://api.clickatell.com/http/sendmsg?to=NUMBER&msg=Message+Body+Here

The SMTP method consists of sending a plain-text e-mail to: [email protected], with the following body:

user: xxxxx
password: xxxxx
api_id: xxxxx
to: 448311234567
text: Meet me at home

You can also test the gateway (incoming and outgoing) for free from your browser

Circa 2019, using jquery, this can be accessed using $('#DOMId').data('typeId') where $('#DOMId') is the jquery selector for your span element.

The dict literal might be a tiny bit faster as its bytecode is shorter:

In [1]: import dis
In [2]: a = lambda: {}
In [3]: b = lambda: dict()

In [4]: dis.dis(a)
  1           0 BUILD_MAP                0
              3 RETURN_VALUE

In [5]: dis.dis(b)
  1           0 LOAD_GLOBAL              0 (dict)
              3 CALL_FUNCTION            0
              6 RETURN_VALUE

Same applies to the list vs []

Booleans default value is false only for classes' fields. If within a method, you have to initialize your variable by true or false. Thus for example in your case, you'll have a compilation error.

Moreover, I don't really get the point, but the only way to enter within a if is to evaluate the condition to true.

The \s regex argument is not compatible with UTF-8 multybyte strings.

This PHP RegEx is one I wrote to solve this using PCRE (Perl Compatible Regular Expressions) based arguments as a replacement for UTF-8 strings:

function remove_utf8_whitespace($string) { 
   return preg_replace('/\h+/u','',preg_replace('/\R+/u','',$string)); 
}

- Example Usage -

Before:

$string = " this is a test \n and another test\n\r\t ok! \n";

echo $string;

 this is a test
 and another test
         ok!

echo strlen($string); // result: 43

After:

$string = remove_utf8_whitespace($string);

echo $string;

thisisatestandanothertestok!

echo strlen($string); // result: 28

scala> val bkb2 = for {
     |   (x, xLab) <- Stream.from(0).breakable   // create breakable sequence with a method
     |   (y, yLab) <- breakable(Stream.from(0))  // create with a function
     |   if (x % 2 == 1) continue(xLab)          // continue to next in outer "x" loop
     |   if (y % 2 == 0) continue(yLab)          // continue to next in inner "y" loop
     |   if (x > 10) break(xLab)                 // break the outer "x" loop
     |   if (y > x) break(yLab)                  // break the inner "y" loop

Upgrading mod_php with Apache

This section describes the upgrade process for a system using Apache as the web server and mod_php to execute PHP code. If, instead, you are running Nginx and PHP-FPM, skip ahead to the next section.

Begin by removing existing PHP packages. Press y and hit Enter to continue when prompted.

sudo yum remove php-cli mod_php php-common

Install the new PHP 7 packages from IUS. Again, press y and Enter when prompted.

sudo yum install mod_php70u php70u-cli php70u-mysqlnd

Finally, restart Apache to load the new version of mod_php:

sudo apachectl restart

You can check on the status of Apache, which is managed by the httpd systemd unit, using systemctl:

systemctl status httpd

Try storing the state in a attribute on the element itself, such as superDirectiveStatus="true"

For example:

angular.module('app')
  .directive('superDirective', function ($compile, $injector) {
    return {
      restrict: 'A',
      replace: true,
      link: function compile(scope, element, attrs) {
        if (element.attr('datepicker')) { // check
          return;
        }
        var status = element.attr('superDirectiveStatus');
        if( status !== "true" ){
             element.attr('datepicker', 'someValue');
             element.attr('datepicker-language', 'en');
             // some more
             element.attr('superDirectiveStatus','true');
             $compile(element)(scope);

        }

      }
    };
  });

I hope this helps you.

I was asking the same question myself and after some research I found something like that.

It works like a charm for me. I use it to remote control my Arduino.

// Buffer to store incoming commands from serial port
String inData;
    
void setup() {
    Serial.begin(9600);
    Serial.println("Serial conection started, waiting for instructions...");
}
    
void loop() {
    while (Serial.available() > 0)
    {
        char recieved = Serial.read();
        inData += recieved; 
    
        // Process message when new line character is recieved
        if (recieved == '\n')
        {
            Serial.print("Arduino Received: ");
            Serial.print(inData);
                
            // You can put some if and else here to process the message juste like that:

            if(inData == "+++\n"){ // DON'T forget to add "\n" at the end of the string.
              Serial.println("OK. Press h for help.");
            }   

    
            inData = ""; // Clear recieved buffer
        }
    }
}

This is very much implementation specific, but the general idea is to allow providers to issue short term access tokens with long term refresh tokens. Why?

• Many providers support bearer tokens which are very weak security-wise. By making them short-lived and requiring refresh, they limit the time an attacker can abuse a stolen token.
• Large scale deployment don't want to perform a database lookup every API call, so instead they issue self-encoded access token which can be verified by decryption. However, this also means there is no way to revoke these tokens so they are issued for a short time and must be refreshed.
• The refresh token requires client authentication which makes it stronger. Unlike the above access tokens, it is usually implemented with a database lookup.

This works perfectly for me try this just put ?rel=0&autoplay=1 in the end of link

<iframe width="631" height="466" src="https://www.youtube.com/embed/UUdMixCYeTA?rel=0&autoplay=1" frameborder="0" allowfullscreen></iframe>

This will return the database name, table name, column name and the datatype of the column specified by a database parameter:

declare @database nvarchar(25)
set @database = ''

cu.COLUMN_NAME,c.DATA_TYPE,c.character_maximum_length
from INFORMATION_SCHEMA.VIEW_COLUMN_USAGE as cu
JOIN INFORMATION_SCHEMA.COLUMNS as c
on cu.TABLE_SCHEMA = c.TABLE_SCHEMA and c.TABLE_CATALOG = 
cu.TABLE_CATALOG
and c.TABLE_NAME = cu.TABLE_NAME
and c.COLUMN_NAME = cu.COLUMN_NAME
where cu.TABLE_CATALOG = @database
order by cu.view_name,c.COLUMN_NAME

final DateTimeFormatter formatter = DateTimeFormatter.ofPattern("dd-MM-yyyy");

I might argue that the answer here generally is "don't". Unless you absolutely need all the data at once, consider using a Stream-based API (or some variant of reader / iterator). That is especially important when you have multiple parallel operations (as suggested by the question) to minimise system load and maximise throughput.

For example, if you are streaming data to a caller:

Stream dest = ...
using(Stream source = File.OpenRead(path)) {
    byte[] buffer = new byte[2048];
    int bytesRead;
    while((bytesRead = source.Read(buffer, 0, buffer.Length)) > 0) {
        dest.Write(buffer, 0, bytesRead);
    }
}

New average = old average * (n-1)/n + new value /n

This is assuming the count only changed by one value. In case it is changed by M values then:

new average = old average * (n-len(M))/n + (sum of values in M)/n).

This is the mathematical formula (I believe the most efficient one), believe you can do further code by yourselves

Here is another one-liner for Java 8.

String ext = Arrays.stream(fileName.split("\\.")).reduce((a,b) -> b).orElse(null)

It works as follows:

1. Split the string into an array of strings using "."
2. Convert the array into a stream
3. Use reduce to get the last element of the stream, i.e. the file extension

you can use something like this :

string [] filePaths = Directory.GetFiles(path, "*.*", SearchOption.AllDirectories);

instead of using "." you can type the name of the file or just the type like "*.txt" also SearchOption.AllDirectories is to search in all subfolders you can change that if you only want one level more about how to use it on here

Here's one suggestion:

public interface Service<T,U> {
    T executeService(U... args);
}

public class MyService implements Service<String, Integer> {
    @Override
    public String executeService(Integer... args) {
        // do stuff
        return null;
    }
}

Because of type erasure any class will only be able to implement one of these. This eliminates the redundant method at least.

It's not an unreasonable interface that you're proposing but I'm not 100% sure of what value it adds either. You might just want to use the standard Callable interface. It doesn't support arguments but that part of the interface has the least value (imho).

I solve problem by adding "arm64" in "Excluded Architectures" for both project target and pod target.

Xcode -> Target Project -> Build Setting -> Excluded Architectures > "arm64"

user1  = pd.read_csv('dataset/1.csv',  names=['Time',  'X',  'Y',  'Z']) 

names parameter in read_csv function is used to define column names. If you pass extra name in this list, it will add another new column with that name with NaN values.

header=None is used to trim column names is already exists in CSV file.

These days, there's a better solution for importing an existing PHP project. The PDT plugin now has an option on the New PHP Project dialog just for this. So:

From File->New->PHP Project:

Seems like both the conditions are met, perhaps key('contact') is the issue

 if(store.telefon) {
    detailItems.push( new DetailItem('contact', store.telefon, 'Anrufen', 'fontawesome|phone') );
}
if(store.email) {
    detailItems.push( new DetailItem('contact', store.email, 'Email', 'fontawesome|envelope') );
}

This takes Test.txt with headers and appends Test1.txt and Test2.txt and writes results to Testresult.txt file after stripping headers from second and third files respectively:

type C:\Test.txt > C:\Testresult.txt && more +1 C:\Test1.txt >> C:\Testresult.txt && more +1 C:\Test2.txt >> C:\Testresult.txt

Step 1: Restart VS Code as an adminstrator

(click the windows key, search for "Visual Studio Code", right click, and you'll see the administrator option)

Step 2: In your VS code powershell terminal run Set-ExecutionPolicy Unrestricted

Start/Exit Method

// Get the parameters/arguments passed to program if any
string arguments = string.Empty;
string[] args = Environment.GetCommandLineArgs();
for (int i = 1; i < args.Length; i++) // args[0] is always exe path/filename
    arguments += args[i] + " ";

// Restart current application, with same arguments/parameters
Application.Exit();
System.Diagnostics.Process.Start(Application.ExecutablePath, arguments);

This seems to work better than Application.Restart();

Not sure how this handles if your program protects against multiple instance. My guess is you would be better off launching a second .exe which pauses and then starts your main application for you.

.NET core 3.X

no need to create new model and to set in Startup.cs.

Controller Add new package - using Microsoft.Extensions.Configuration;

public class HomeController : Controller
{
    private readonly IConfiguration _mySettings;

    public HomeController (IConfiguration mySettings)
    {
         _mySettings= mySettings;
    }
 
    //ex: you can get value on below function 
    public IEnumerable<string> Get()
    {
        var result = _config.GetValue<string>("AppSettings:Version"); // "One"
        return new string[] { result.ToString() };
    }
}

If you need to work a lot with database in your code and you know the structure of your table, I suggest you do it as follow:

First of all you can define a class which will help you to make objects capable of keeping your table rows data. For example in my project I created a class named Document.java to keep data of a single document from my database and I made an array list of these objects to keep data of my table which is gain by a query.

package financialdocuments;

import java.lang.*;
import java.util.HashMap;

/**
 *
 * @author Administrator
 */
public class Document {

 private int document_number; 
 private boolean document_type;
 private boolean document_status; 
 private StringBuilder document_date;
 private StringBuilder document_statement;
 private int document_code_number;
 private int document_employee_number;
 private int document_client_number;
 private String document_employee_name;
 private String document_client_name;
 private long document_amount;
 private long document_payment_amount;

 HashMap<Integer,Activity> document_activity_hashmap;


public Document(int dn,boolean dt,boolean ds,String dd,String dst,int dcon,int den,int dcln,long da,String dena,String dcna){

    document_date = new StringBuilder(dd);
    document_date.setLength(10);
    document_date.setCharAt(4, '.');
    document_date.setCharAt(7, '.');
    document_statement = new StringBuilder(dst);
    document_statement.setLength(50);
    document_number = dn; 
    document_type = dt;
    document_status = ds;
    document_code_number = dcon;
    document_employee_number = den;
    document_client_number = dcln;
    document_amount = da;
    document_employee_name = dena;
    document_client_name = dcna;

    document_payment_amount = 0;

    document_activity_hashmap = new HashMap<>();

}

public Document(int dn,boolean dt,boolean ds, long dpa){

    document_number = dn; 
    document_type = dt;
    document_status = ds;

    document_payment_amount = dpa;

    document_activity_hashmap = new HashMap<>();

}

// Print document information 
public void printDocumentInformation (){
    System.out.println("Document Number:" + document_number); 
    System.out.println("Document Date:" + document_date); 
    System.out.println("Document Type:" + document_type); 
    System.out.println("Document Status:" + document_status); 
    System.out.println("Document Statement:" + document_statement); 
    System.out.println("Document Code Number:" + document_code_number); 
    System.out.println("Document Client Number:" + document_client_number); 
    System.out.println("Document Employee Number:" + document_employee_number); 
    System.out.println("Document Amount:" + document_amount); 
    System.out.println("Document Payment Amount:" + document_payment_amount); 
    System.out.println("Document Employee Name:" + document_employee_name); 
    System.out.println("Document Client Name:" + document_client_name); 

} 
} 

Second of all, you can define a class to handle your database needs. For example I defined a class named DataBase.java which handles my connections to the database and my needed queries. And I instantiated an objected of it in my main class.

package financialdocuments;

import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;

import java.util.logging.Logger;

I hope this could be a little help.

Try these CI functions

$this->db->_error_message(); (mysql_error equivalent)
$this->db->_error_number(); (mysql_errno equivalent)

UPDATE FOR CODEIGNITER 3

Functions are deprecated, use error() instead:

$this->db->error(); 

you can call javascript version of onload event in angular js. this ng-load event can be applied to any dom element like div, span, body, iframe, img etc. following is the link to add ng-load in your existing project.

download ng-load for angular js

Following is example for iframe, once it is loaded testCallbackFunction will be called in controller

EXAMPLE

JS

    // include the `ngLoad` module
    var app = angular.module('myApp', ['ngLoad']);
    app.controller('myCtrl', function($scope) {
        $scope.testCallbackFunction = function() {
          //TODO : Things to do once Element is loaded
        };

    });  

HTML

  <div ng-app='myApp' ng-controller='myCtrl'> 
      <iframe src="test.html" ng-load callback="testCallbackFunction()">  
  </div>

If you are going to ALTER Table column and immediate UPDATE the table including the new column in the same script. Make sure that use GO command to after line of code of alter table as below.

ALTER TABLE Location 
ADD TransitionType SMALLINT NULL
GO   

UPDATE Location SET TransitionType =  4

ALTER TABLE Location 
    ALTER COLUMN TransitionType SMALLINT NOT NULL

One option, if you're looking for the actual queried page, rather than the page ID or slug is to intercept the query:

add_action('parse_request', 'show_query', 10, 1);

Within your function, you have access to the $wp object and you can get either the pagename or the post name with:

function show_query($wp){
     if ( ! is_admin() ){ // heck we don't need the admin pages
         echo $wp->query_vars['pagename'];
         echo $wp->query_vars['name'];
     }
}

If, on the other hand, you really need the post data, the first place to get it (and arguably in this context, the best) is:

add_action('wp', 'show_page_name', 10, 1);

function show_page_name($wp){
     if ( ! is_admin() ){
        global $post;
        echo $post->ID, " : ", $post->post_name;
     }
}

Finally, I realize this probably wasn't the OP's question, but if you're looking for the Admin page name, use the global $pagenow.

Easy way to parse the xml is to use the LINQ to XML

for example you have the following xml file

<library>
    <track id="1" genre="Rap" time="3:24">
        <name>Who We Be RMX (feat. 2Pac)</name>
        <artist>DMX</artist>
        <album>The Dogz Mixtape: Who's Next?!</album>
    </track>
    <track id="2" genre="Rap" time="5:06">
        <name>Angel (ft. Regina Bell)</name>
        <artist>DMX</artist>
        <album>...And Then There Was X</album>
    </track>
    <track id="3" genre="Break Beat" time="6:16">
        <name>Dreaming Your Dreams</name>
        <artist>Hybrid</artist>
        <album>Wide Angle</album>
    </track>
    <track id="4" genre="Break Beat" time="9:38">
        <name>Finished Symphony</name>
        <artist>Hybrid</artist>
        <album>Wide Angle</album>
    </track>
<library>

For reading this file, you can use the following code:

public void Read(string  fileName)
{
    XDocument doc = XDocument.Load(fileName);

    foreach (XElement el in doc.Root.Elements())
    {
        Console.WriteLine("{0} {1}", el.Name, el.Attribute("id").Value);
        Console.WriteLine("  Attributes:");
        foreach (XAttribute attr in el.Attributes())
            Console.WriteLine("    {0}", attr);
        Console.WriteLine("  Elements:");

        foreach (XElement element in el.Elements())
            Console.WriteLine("    {0}: {1}", element.Name, element.Value);
    }
}

1. fs.readdir(path, callback)
2. fs.rename(old,new,callback)

Go through http://nodejs.org/api/fs.html

One important thing - you can use sync functions also. (It will work like C program)

My problem was solved with this solution:

static void Main(string[] args)
        {
            var date1 = new DateTime(2018, 12, 05);
            var date2 = new DateTime(2019, 03, 01);

            int CountNumberOfMonths() => (date2.Month - date1.Month) + 12 * (date2.Year - date1.Year);

            var numberOfMonths = CountNumberOfMonths();

            Console.WriteLine("Number of months between {0} and {1}: {2} months.", date1.ToString(), date2.ToString(), numberOfMonths.ToString());

            Console.ReadKey();

            //
            // *** Console Output:
            // Number of months between 05/12/2018 00:00:00 and 01/03/2019 00:00:00: 3 months.
            //

        }

You can either abort the merge step:

git merge --abort

else you can keep your changes (on which branch you are)

git checkout --ours file1 file2 ...

otherwise you can keep other branch changes

git checkout --theirs file1 file2 ...

For me the problem was a configuration file that was missing an Element.

These are compact methods to encrypt / decrypt strings with PHP using AES256 CBC:

function encryptString($plaintext, $password, $encoding = null) {
    $iv = openssl_random_pseudo_bytes(16);
    $ciphertext = openssl_encrypt($plaintext, "AES-256-CBC", hash('sha256', $password, true), OPENSSL_RAW_DATA, $iv);
    $hmac = hash_hmac('sha256', $ciphertext.$iv, hash('sha256', $password, true), true);
    return $encoding == "hex" ? bin2hex($iv.$hmac.$ciphertext) : ($encoding == "base64" ? base64_encode($iv.$hmac.$ciphertext) : $iv.$hmac.$ciphertext);
}

function decryptString($ciphertext, $password, $encoding = null) {
    $ciphertext = $encoding == "hex" ? hex2bin($ciphertext) : ($encoding == "base64" ? base64_decode($ciphertext) : $ciphertext);
    if (!hash_equals(hash_hmac('sha256', substr($ciphertext, 48).substr($ciphertext, 0, 16), hash('sha256', $password, true), true), substr($ciphertext, 16, 32))) return null;
    return openssl_decrypt(substr($ciphertext, 48), "AES-256-CBC", hash('sha256', $password, true), OPENSSL_RAW_DATA, substr($ciphertext, 0, 16));
}

Usage:

$enc = encryptString("mysecretText", "myPassword");
$dec = decryptString($enc, "myPassword");

public func jsonPrint(_ o: NSObject, spacing: String = "", after: String = "", before: String = "") {
    let newSpacing = spacing + "    "
    if o.isArray() {
        print(before + "[")
        if let a = o as? Array<NSObject> {
            for object in a {
                jsonPrint(object, spacing: newSpacing, after: object == a.last! ? "" : ",", before: newSpacing)
            }
        }
        print(spacing + "]" + after)
    } else {
        if o.isDictionary() {
            print(before + "{")
            if let a = o as? Dictionary<NSObject, NSObject> {
                for (key, val) in a {
                    jsonPrint(val, spacing: newSpacing, after: ",", before: newSpacing + key.description + " = ")
                }
            }
            print(spacing + "}" + after)
        } else {
            print(before + o.description + after)
        }
    }
}

I followed this tutorial: How to install Maven on Windows

But running mvn -version, I still got:

mvn: command not found

So, I closed the current git window, and opened a new one. Everything went okay :)

Because there's more than one way to skin a cat:

psql -l

Shows all the database names, encoding, and more.

Try to use r.hasNext() instead of r.hasNextLine():

while(r.hasNext()) {
        scan = r.next();

How do I list all collections for the current database that I'm using?

Three methods

• show collections
• show tables
• db.getCollectionNames()

To list all databases:

show dbs

To enter or use a given database:

use databasename

To list all collections:

show collections

Output:

collection1
collection2
system.indexes

(or)

show tables

Output:

collection1
collection2
system.indexes

(or)

db.getCollectionNames()

Output:

[ "collection1", "collection2", "system.indexes" ]

To enter or use given collection

use collectionname

In my (linux mint) system I can not get working combination alt+insert so I do the next steps:

alt+1 (navigate to "tree") --> "context button - analog right mouse click" (between right alt and ctrl) -- then with arrows (up or down) desired choice (create new class or package or ...)

Hope it helps some "mint" owners )).

Nice Explanation from http://www.programmerinterview.com/index.php/data-structures/dfs-vs-bfs/

An example of BFS

Here’s an example of what a BFS would look like. This is something like Level Order Tree Traversal where we will use QUEUE with ITERATIVE approach (Mostly RECURSION will end up with DFS). The numbers represent the order in which the nodes are accessed in a BFS:

In a depth first search, you start at the root, and follow one of the branches of the tree as far as possible until either the node you are looking for is found or you hit a leaf node ( a node with no children). If you hit a leaf node, then you continue the search at the nearest ancestor with unexplored children.

An example of DFS

Here’s an example of what a DFS would look like. I think post order traversal in binary tree will start work from the Leaf level first. The numbers represent the order in which the nodes are accessed in a DFS:

Differences between DFS and BFS

Comparing BFS and DFS, the big advantage of DFS is that it has much lower memory requirements than BFS, because it’s not necessary to store all of the child pointers at each level. Depending on the data and what you are looking for, either DFS or BFS could be advantageous.

For example, given a family tree if one were looking for someone on the tree who’s still alive, then it would be safe to assume that person would be on the bottom of the tree. This means that a BFS would take a very long time to reach that last level. A DFS, however, would find the goal faster. But, if one were looking for a family member who died a very long time ago, then that person would be closer to the top of the tree. Then, a BFS would usually be faster than a DFS. So, the advantages of either vary depending on the data and what you’re looking for.

One more example is Facebook; Suggestion on Friends of Friends. We need immediate friends for suggestion where we can use BFS. May be finding the shortest path or detecting the cycle (using recursion) we can use DFS.

Example example;

Here example is an object on the stack.

Example* example=new Example();

This could be broken into:

Example* example;
....
example=new Example();

Here the first statement creates a variable example which is a "pointer to Example". When the constructor is called, memory is allocated for it on the heap (dynamic allocation). It is the programmer's responsibility to free this memory when it is no longer needed. (C++ does not have garbage collection like java).

The reason why you don't have to load a certificate locally is that you've explicitly chosen not to verify the certificate, with this trust manager that trusts all certificates.

The traffic will still be encrypted, but you're opening the connection to Man-In-The-Middle attacks: you're communicating secretly with someone, you're just not sure whether it's the server you expect, or a possible attacker.

If your server certificate comes from a well-known CA, part of the default bundle of CA certificates bundled with the JRE (usually cacerts file, see JSSE Reference guide), you can just use the default trust manager, you don't have to set anything here.

If you have a specific certificate (self-signed or from your own CA), you can use the default trust manager or perhaps one initialised with a specific truststore, but you'll have to import the certificate explicitly in your trust store (after independent verification), as described in this answer.

This works fine for me (Apache 2.4/PHP 7.0):

@ob_end_clean();
echo "lorem ipsum...";
flush();
sleep(5);
echo "<br>dolor...";
flush();
sleep(5);
echo "<br>sit amet";

As said already in the comments you can use the csv library in python. csv means comma separated values which seems exactly your case: a label and a value separated by a comma.

Being a category and value type I would rather use a dictionary type instead of a list of tuples.

Anyway in the code below I show both ways: d is the dictionary and l is the list of tuples.

import csv

file_name = "test.txt"
try:
    csvfile = open(file_name, 'rt')
except:
    print("File not found")
csvReader = csv.reader(csvfile, delimiter=",")
d = dict()
l =  list()
for row in csvReader:
    d[row[1]] = row[0]
    l.append((row[0], row[1]))
print(d)
print(l)

The accepted answer is fine if you can use lookarounds. However, there is also another approach to solve this problem.

If we look at the widely proposed regex for this question:

.*[^a]$

We will find that it almost works. It does not accept an empty string, which might be a little inconvinient. However, this is a minor issue when dealing with just a one character. However, if we want to exclude whole string, e.g. "abc", then:

.*[^a][^b][^c]$

won't do. It won't accept ac, for example.

There is an easy solution for this problem though. We can simply say:

.{,2}$|.*[^a][^b][^c]$

or more generalized version:

.{,n-1}$|.*[^firstchar][^secondchar]$ where n is length of the string you want forbid (for abc it's 3), and firstchar, secondchar, ... are first, second ... nth characters of your string (for abc it would be a, then b, then c).

This comes from a simple observation that a string that is shorter than the text we won't forbid can not contain this text by definition. So we can either accept anything that is shorter("ab" isn't "abc"), or anything long enough for us to accept but without the ending.

Here's an example of find that will delete all files that are not .jpg:

find . -regex '.{,3}$|.*[^.][^j][^p][^g]$' -delete

We do a lot of joins and composite primary keys have just become a performance hog. A simple int or long takes care of many problems even though you are introducing a second candidate key, but it's a lot easier and more understandable to join on one field versus three.

This normally happens when the transaction is started and either it is not committed or it is not rollback.

In case the error comes in your stored procedure, this can lock the database tables because transaction is not completed due to some runtime errors in the absence of exception handling You can use Exception handling like below. SET XACT_ABORT

SET XACT_ABORT ON
SET NoCount ON
Begin Try 
     BEGIN TRANSACTION 
        //Insert ,update queries    
     COMMIT
End Try 
Begin Catch 
     ROLLBACK
End Catch

Python is case sensitive and needs proper indentation. You need to use lowercase "if", indent your conditions properly and the code has a bug. proceed will evaluate to y

after doing some digging I found a good way to accomplish what I need with ITextSharp.

Here is some sample code if it will help anyone else in the future:

protected void Page_Load(object sender, EventArgs e)
{
    Document document = new Document();
    try
    {
        PdfWriter.GetInstance(document, new FileStream("c:\\my.pdf", FileMode.Create));
        document.Open();
        WebClient wc = new WebClient();
        string htmlText = wc.DownloadString("http://localhost:59500/my.html");
        Response.Write(htmlText);
        List<IElement> htmlarraylist = HTMLWorker.ParseToList(new StringReader(htmlText), null);
        for (int k = 0; k < htmlarraylist.Count; k++)
        {
            document.Add((IElement)htmlarraylist[k]);
        }

        document.Close();
    }
    catch
    {
    }
}

You can use Collections.sort(list) to sort list if your list contains Comparable elements. Otherwise I would recommend you to implement that interface like here:

public class Circle implements Comparable<Circle> {}

and of course provide your own realization of compareTo method like here:

@Override
    public int compareTo(Circle another) {
        if (this.getD()<another.getD()){
            return -1;
        }else{
            return 1;
        }
    }

And then you can again use Colection.sort(list) as now list contains objects of Comparable type and can be sorted. Order depends on compareTo method. Check this https://docs.oracle.com/javase/tutorial/collections/interfaces/order.html for more detailed information.

I came across this question as I had exact same problem. Although accepted answer works good but with matplotlib version 2.1.0, it is pretty straight forward to have two scatter plots in one plot without using a reference to Axes

import matplotlib.pyplot as plt

plt.scatter(x,y, c='b', marker='x', label='1')
plt.scatter(x, y, c='r', marker='s', label='-1')
plt.legend(loc='upper left')
plt.show()

I was also wondering how to store it cleanly in a variable. As using

char c = '•';

is not very good practice (I guess). I found out the following way of storing it in a variable

char c = (char)0x2022;// or 0x25cf depending on the one you choose

or even cleaner

char c = '\u2022';// or "\u25cf"

https://msdn.microsoft.com/en-us/library/aa664669%28v=vs.71%29.aspx

same for strings

string s = "\u2022";

https://msdn.microsoft.com/en-us/library/362314fe.aspx

None of the tips in the best answer worked for me. Was going crazy. Then noticed that the Assistant Editor had somehow gotten set to Manual and I was on the ViewController.swift (Interface) instead of the ViewController.swift file.

Changed that and problem solved. A bit embarrassing but hey, we are all learning.

Easiest way: You should create a new emulator, before opening it for the first time follow these 3 easy steps:

1- go to C:\Users[user].android\avd[your virtual device folder] open "config.ini" with text editor like notepad

2- change

"PlayStore.enabled=false" to "PlayStore.enabled=true"

3- change

mage.sysdir.1 = system-images\android-30\google_apis\x86\

to

image.sysdir.1 = system-images\android-30\google_apis_playstore\x86\

Here's how to disable minification on a per-bundle basis:

bundles.Add(new StyleBundleRaw("~/Content/foobarcss").Include("/some/path/foobar.css"));
bundles.Add(new ScriptBundleRaw("~/Bundles/foobarjs").Include("/some/path/foobar.js"));

Sidenote: The paths used for your bundles must not coincide with any actual path in your published builds otherwise nothing will work. Also make sure to avoid using .js, .css and/or '.' and '_' anywhere in the name of the bundle. Keep the name as simple and as straightforward as possible, like in the example above.

The helper classes are shown below. Notice that in order to make these classes future-proof we surgically remove the js/css minifying instances instead of using .clear() and we also insert a mime-type-setter transformation without which production builds are bound to run into trouble especially when it comes to properly handing over css-bundles (firefox and chrome reject css bundles with mime-type set to "text/html" which is the default):

internal sealed class StyleBundleRaw : StyleBundle
{
        private static readonly BundleMimeType CssContentMimeType = new BundleMimeType("text/css");

        public StyleBundleRaw(string virtualPath) : this(virtualPath, cdnPath: null)
        {
        }

        public StyleBundleRaw(string virtualPath, string cdnPath) : base(virtualPath, cdnPath)
        {
                 Transforms.Add(CssContentMimeType); //0 vital
                 Transforms.Remove(Transforms.FirstOrDefault(x => x is CssMinify)); //0
        }
        //0 the guys at redmond in their infinite wisdom plugged the mimetype "text/css" right into cssminify    upon unwiring the minifier we
        //  need to somehow reenable the cssbundle to specify its mimetype otherwise it will advertise itself as html and wont load
}

internal sealed class ScriptBundleRaw : ScriptBundle
{
        private static readonly BundleMimeType JsContentMimeType = new BundleMimeType("text/javascript");

        public ScriptBundleRaw(string virtualPath) : this(virtualPath, cdnPath: null)
        {
        }

        public ScriptBundleRaw(string virtualPath, string cdnPath) : base(virtualPath, cdnPath)
        {
                 Transforms.Add(JsContentMimeType); //0 vital
                 Transforms.Remove(Transforms.FirstOrDefault(x => x is JsMinify)); //0
        }
        //0 the guys at redmond in their infinite wisdom plugged the mimetype "text/javascript" right into jsminify   upon unwiring the minifier we need
        //  to somehow reenable the jsbundle to specify its mimetype otherwise it will advertise itself as html causing it to be become unloadable by the browsers in published production builds
}

internal sealed class BundleMimeType : IBundleTransform
{
        private readonly string _mimeType;

        public BundleMimeType(string mimeType) { _mimeType = mimeType; }

        public void Process(BundleContext context, BundleResponse response)
        {
                 if (context == null)
                          throw new ArgumentNullException(nameof(context));
                 if (response == null)
                          throw new ArgumentNullException(nameof(response));

         response.ContentType = _mimeType;
        }
}

To make this whole thing work you need to install (via nuget):

WebGrease 1.6.0+ Microsoft.AspNet.Web.Optimization 1.1.3+

And your web.config should be enriched like so:

<runtime>

Note that you might have to take extra steps to make your css-bundles work in terms of fonts etc. But that's a different story.

Absolutely. Try this:

Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"), PICK_IMAGE);

Don't forget also to create the constant PICK_IMAGE, so you can recognize when the user comes back from the image gallery Activity:

public static final int PICK_IMAGE = 1;

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data)
{
    if (requestCode == PICK_IMAGE) {
        //TODO: action
    }
}

That's how I call the image gallery. Put it in and see if it works for you.

EDIT:

This brings up the Documents app. To allow the user to also use any gallery apps they might have installed:

    Intent getIntent = new Intent(Intent.ACTION_GET_CONTENT);
    getIntent.setType("image/*");

    Intent pickIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
    pickIntent.setType("image/*");

    Intent chooserIntent = Intent.createChooser(getIntent, "Select Image");
    chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, new Intent[] {pickIntent});

    startActivityForResult(chooserIntent, PICK_IMAGE);

Built-in support since Handlebars 1.0rc1

Support for this functionality has been added to Handlebars.js, so there is no more need for external helpers.

How to use it

For arrays:

{{#each myArray}}
    Index: {{@index}} Value = {{this}}
{{/each}}

For objects:

{{#each myObject}}
    Key: {{@key}} Value = {{this}}
{{/each}}

Note that only properties passing the hasOwnProperty test will be enumerated.

Put simply, __name__ is a variable defined for each script that defines whether the script is being run as the main module or it is being run as an imported module.

So if we have two scripts;

#script1.py
print "Script 1's name: {}".format(__name__)

and

#script2.py
import script1
print "Script 2's name: {}".format(__name__)

The output from executing script1 is

Script 1's name: __main__

And the output from executing script2 is:

Script1's name is script1
Script 2's name: __main__

As you can see, __name__ tells us which code is the 'main' module. This is great, because you can just write code and not have to worry about structural issues like in C/C++, where, if a file does not implement a 'main' function then it cannot be compiled as an executable and if it does, it cannot then be used as a library.

Say you write a Python script that does something great and you implement a boatload of functions that are useful for other purposes. If I want to use them I can just import your script and use them without executing your program (given that your code only executes within the if __name__ == "__main__": context). Whereas in C/C++ you would have to portion out those pieces into a separate module that then includes the file. Picture the situation below;

The arrows are import links. For three modules each trying to include the previous modules code there are six files (nine, counting the implementation files) and five links. This makes it difficult to include other code into a C project unless it is compiled specifically as a library. Now picture it for Python:

You write a module, and if someone wants to use your code they just import it and the __name__ variable can help to separate the executable portion of the program from the library part.

As to the "problem" of what key to press to close it, I (and thousands of others, I'm sure) simply use input("Press Enter to close").

If a special character other than $, _, and # is used in the name of a column or table, the name must be enclosed in double quotations. Link

My Moving Average function, without numpy function:

from __future__ import division  # must be on first line of script

class Solution:
    def Moving_Avg(self,A):
        m = A[0]
        B = []
        B.append(m)
        for i in range(1,len(A)):
            m = (m * i + A[i])/(i+1)
            B.append(m)
        return B

Try this simple function to add an dictionary item if it does not exist or update when it exists:

    public void AddOrUpdateDictionaryEntry(string key, int value)
    {
        if (dict.ContainsKey(key))
        {
            dict[key] = value;
        }
        else
        {
            dict.Add(key, value);
        }
    }

This is the same as dict[key] = value.

Same thing is happened with 8.0+ versions as well. By default in 8.0+ version it is "enabled" by default. Here is the link official document reference

In case of 5.6+, 5.7+ versions, the property "ONLY_FULL_GROUP_BY" is disabled by default.

To disabled it, follow the same steps suggested by @Miloud BAKTETE

There is no need to use the classpath: protocol in your schemaLocation URL if the namespace is configured correctly and the XSD file is on your classpath.

Spring doc "Registering the handler and the schema" shows how it should be done.

In your case, the problem was probably that the spring-context jar on your classpath was not 2.1. That was why changing the protocol to classpath: and putting the specific 2.1 XSD in your classpath fixed the problem.

From what I've seen, there are 2 schemas defined for the main XSD contained in a spring-* jar. Once to resolve the schema URL with the version and once without it.

As an example see this part of the spring.schemas contents in spring-context-3.0.5.RELEASE.jar:

http\://www.springframework.org/schema/context/spring-context-2.5.xsd=org/springframework/context/config/spring-context-2.5.xsd
http\://www.springframework.org/schema/context/spring-context-3.0.xsd=org/springframework/context/config/spring-context-3.0.xsd
http\://www.springframework.org/schema/context/spring-context.xsd=org/springframework/context/config/spring-context-3.0.xsd

This means that (in xsi:schemaLocation)

http://www.springframework.org/schema/context/spring-context-2.5.xsd 

will be validated against

org/springframework/context/config/spring-context-2.5.xsd 

in the classpath.

http://www.springframework.org/schema/context/spring-context-3.0.xsd 

or

http://www.springframework.org/schema/context/spring-context.xsd

will be validated against

org/springframework/context/config/spring-context-3.0.xsd 

in the classpath.

http://www.springframework.org/schema/context/spring-context-2.1.xsd

is not defined so Spring will look for it using the literal URL defined in schemaLocation.

I had the same problem as you mentioned here above and my code was doing great all day yesterday.

I kept on programming this morning and when I opened my application (my file with an Auto_Open sub), I got the Run-time error '13' Type mismatch, I went on the web to find answers, I tried a lot of things, modifications and at one point I remembered that I read somewhere about "Ghost" data that stays in a cell even if we don't see it.

My code do only data transfer from one file I opened previously to another and Sum it. My code stopped at the third SheetTab (So it went right for the 2 previous SheetTab where the same code went without stopping) with the Type mismatch message. And it does that every time at the same SheetTab when I restart my code.

So I selected the cell where it stopped, manually entered 0,00 (Because the Type mismatch comes from a Summation variables declared in a DIM as Double) and copied that cell in all the subsequent cells where the same problem occurred. It solved the problem. Never had the message again. Nothing to do with my code but the "Ghost" or data from the past. It is like when you want to use the Control+End and Excel takes you where you had data once and deleted it. Had to "Save" and close the file when you wanted to use the Control+End to make sure Excel pointed you to the right cell.

For performance I would go with drphrozens solution. A tiny optimization for the decoder could be to use a table for either char to get rid of the "<< 4".

Clearly the two method calls are costly. If some kind of check is made either on input or output data (could be CRC, checksum or whatever) the if (b == 255)... could be skipped and thereby also the method calls altogether.

Using offset++ and offset instead of offset and offset + 1 might give some theoretical benefit but I suspect the compiler handles this better than me.

This is just off the top of my head and has not been tested or benchmarked.

Another way :

change BOT_USER_NAME before use

https://telegram.me/BOT_USER_NAME?startgroup=true

Override Fragment.onHiddenChanged() for that.

public void onHiddenChanged(boolean hidden)

Called when the hidden state (as returned by isHidden()) of the fragment has changed. Fragments start out not hidden; this will be called whenever the fragment changes state from that.

Parameters
hidden - boolean: True if the fragment is now hidden, false if it is not visible.

I assume you have your JS file declared inside the <head> tag so it keeps it consistent, like standard, then in your JS make sure the canvas initialization is after the page is loaded:

window.onload = function () {
    var myCanvas = document.getElementById('canvas');
    var ctx = myCanvas.getContext('2d');
}

There is no need to use jQuery just to initialize a canvas, it's very evident most of the programmers all around the world use it unnecessarily and the accepted answer is a probe of that.

Well if you want fully transparent than you can use

border: 5px solid transparent;

If you mean opaque/transparent, than you can use

border: 5px solid rgba(255, 255, 255, .5);

Here, a means alpha, which you can scale, 0-1.

Also some might suggest you to use opacity which does the same job as well, the only difference is it will result in child elements getting opaque too, yes, there are some work arounds but rgba seems better than using opacity.

For older browsers, always declare the background color using #(hex) just as a fall back, so that if old browsers doesn't recognize the rgba, they will apply the hex color to your element.

Demo

Demo 2 (With a background image for nested div)

Demo 3 (With an img tag instead of a background-image)

body {
    background: url(http://www.desktopas.com/files/2013/06/Images-1920x1200.jpg);   
}

div.wrap {
    border: 5px solid #fff; /* Fall back, not used in fiddle */
    border: 5px solid rgba(255, 255, 255, .5);
    height: 400px;
    width: 400px;
    margin: 50px;
    border-radius: 50%;
}

div.inner {
    background: #fff; /* Fall back, not used in fiddle */
    background: rgba(255, 255, 255, .5);
    height: 380px;
    width: 380px;
    border-radius: 50%; 
    margin: auto; /* Horizontal Center */
    margin-top: 10px; /* Vertical Center ... Yea I know, that's 
                         manually calculated*/
}

Note (For Demo 3): Image will be scaled according to the height and width provided so make sure it doesn't break the scaling ratio.

You should be using SqlConnection.State

e.g,

using System.Data;

if (myConnection != null && myConnection.State == ConnectionState.Closed)
{
   // do something
   // ...
}

It is possible to use a handler to do this, even in MVC4. Here's an example from one i made earlier:

public class ImageHandler : IHttpHandler
{
    byte[] bytes;

    public void ProcessRequest(HttpContext context)
    {
        int param;
        if (int.TryParse(context.Request.QueryString["id"], out param))
        {
            using (var db = new MusicLibContext())
            {
                if (param == -1)
                {
                    bytes = File.ReadAllBytes(HttpContext.Current.Server.MapPath("~/Images/add.png"));

                    context.Response.ContentType = "image/png";
                }
                else
                {
                    var data = (from x in db.Images
                                where x.ImageID == (short)param
                                select x).FirstOrDefault();

                    bytes = data.ImageData;

                    context.Response.ContentType = "image/" + data.ImageFileType;
                }

                context.Response.Cache.SetCacheability(HttpCacheability.NoCache);
                context.Response.BinaryWrite(bytes);
                context.Response.Flush();
                context.Response.End();
            }
        }
        else
        {
            //image not found
        }
    }

    public bool IsReusable
    {
        get
        {
            return false;
        }
    }
}

In the view, i added the ID of the photo to the query string of the handler.

Add this 2 lines in your code -

mWebView.setWebChromeClient(new WebChromeClient()); 
mWebView.setWebViewClient(new WebViewClient());?

Because LINQ can do everything...:

string test = "key1=value1&key2=value2&key3=value3";
var count = test.Where(x => x == '&').Count();

Or if you like, you can use the Count overload that takes a predicate :

var count = test.Count(x => x == '&');

You should post a message from frame to parent, after loaded.

frame script:

$(document).ready(function() {
    window.parent.postMessage("I'm loaded", "*");
});

And listen it in parent:

function listenMessage(msg) {
    alert(msg);
}

if (window.addEventListener) {
    window.addEventListener("message", listenMessage, false);
} else {
    window.attachEvent("onmessage", listenMessage);
}

Use this link for more info: http://en.wikipedia.org/wiki/Web_Messaging

EDIT: http://jsfiddle.net/nCFGL/223/ My Example.

You should be able to like follows:

var pieData = [{
    value: 30,
    color: "#F38630",
    label: 'Sleep',
    labelColor: 'white',
    labelFontSize: '16'
  },
  ...
];

Some more options. In Ipython with pylab enabled, dedent is already in the namespace. I checked and it is from matplotlib. Or it can be imported with:

from matplotlib.cbook import dedent

In documentation it states that it is faster than the textwrap equivalent one and in my tests in ipython it is indeed 3 times faster on average with my quick tests. It also has the benefit that it discards any leading blank lines this allows you to be flexible in how you construct the string:

"""
line 1 of string
line 2 of string
"""

"""\
line 1 of string
line 2 of string
"""

"""line 1 of string
line 2 of string
"""

Using the matplotlib dedent on these three examples will give the same sensible result. The textwrap dedent function will have a leading blank line with 1st example.

Obvious disadvantage is that textwrap is in standard library while matplotlib is external module.

Some tradeoffs here... the dedent functions make your code more readable where the strings get defined, but require processing later to get the string in usable format. In docstrings it is obvious that you should use correct indentation as most uses of the docstring will do the required processing.

When I need a non long string in my code I find the following admittedly ugly code where I let the long string drop out of the enclosing indentation. Definitely fails on "Beautiful is better than ugly.", but one could argue that it is simpler and more explicit than the dedent alternative.

def example():
    long_string = '''\
Lorem ipsum dolor sit amet, consectetur adipisicing
elit, sed do eiusmod tempor incididunt ut labore et
dolore magna aliqua. Ut enim ad minim veniam, quis
nostrud exercitation ullamco laboris nisi ut aliquip.\
'''
    return long_string
