Tried multiple of these, I switched to Cygwin instead which fixed python and some other problems I was having on Windows:

You may store the parameters for the blob detector in a file, but this is not necessary. Example:

// set up the parameters (check the defaults in opencv's code in blobdetector.cpp)
cv::SimpleBlobDetector::Params params;
params.minDistBetweenBlobs = 50.0f;
params.filterByInertia = false;
params.filterByConvexity = false;
params.filterByColor = false;
params.filterByCircularity = false;
params.filterByArea = true;
params.minArea = 20.0f;
params.maxArea = 500.0f;
// ... any other params you don't want default value

// set up and create the detector using the parameters
cv::SimpleBlobDetector blob_detector(params);
// or cv::Ptr<cv::SimpleBlobDetector> detector = cv::SimpleBlobDetector::create(params)

// detect!
vector<cv::KeyPoint> keypoints;
blob_detector.detect(image, keypoints);

// extract the x y coordinates of the keypoints: 

for (int i=0; i<keypoints.size(); i++){
    float X = keypoints[i].pt.x; 
    float Y = keypoints[i].pt.y;
}

Move DropDownList1.Items.Add(new ListItem("Select", "0", true)); After bindStatusDropDownList();

so:

    if (!IsPostBack)
    {
        bindStatusDropDownList(); //first create structure
        DropDownList1.Items.Add(new ListItem("Select", "0", true)); // after add item
    }

$(element).prop('disabled', true); //true|disabled will work on all
$(element).attr('disabled', true); 
element.disabled = true;
element.setAttribute('disabled', true);

All of the above are perfectly valid solutions. Choose the one that fits your needs best.

I had the same issue of multiple DocumentCompleted fired events and tried out all the suggestions above. Finally, seems that in my case neither IsBusy property works right nor Url property, but the ReadyState seems to be what I needed, because it has the status 'Interactive' while loading the multiple frames and it gets the status 'Complete' only after loading the last one. Thus, I know when the page is fully loaded with all its components.

I hope this may help others too :)

Edit: isaykatsman has a pytorch PR to add a model.summary() that is exactly like keras https://github.com/pytorch/pytorch/pull/3043/files

Path.GetDirectoryName()... but you need to know that the path you are passing to it does contain a file name; it simply removes the final bit from the path, whether it is a file name or directory name (it actually has no idea which).

You could validate first by testing File.Exists() and/or Directory.Exists() on your path first to see if you need to call Path.GetDirectoryName

Hi Please find the answer below.this is done by validating the date newly created

var year=2019;
var month=2;
var date=31;
var d = new Date(year, month - 1, date);
if (d.getFullYear() != year
        || d.getMonth() != (month - 1)
        || d.getDate() != date) {
    alert("invalid date");
    return false;
}

Introduction

You can get everything through ExternalContext. In JSF 1.x, you can get the raw HttpServletResponse object by ExternalContext#getResponse(). In JSF 2.x, you can use the bunch of new delegate methods like ExternalContext#getResponseOutputStream() without the need to grab the HttpServletResponse from under the JSF hoods.

On the response, you should set the Content-Type header so that the client knows which application to associate with the provided file. And, you should set the Content-Length header so that the client can calculate the download progress, otherwise it will be unknown. And, you should set the Content-Disposition header to attachment if you want a Save As dialog, otherwise the client will attempt to display it inline. Finally just write the file content to the response output stream.

Most important part is to call FacesContext#responseComplete() to inform JSF that it should not perform navigation and rendering after you've written the file to the response, otherwise the end of the response will be polluted with the HTML content of the page, or in older JSF versions, you will get an IllegalStateException with a message like getoutputstream() has already been called for this response when the JSF implementation calls getWriter() to render HTML.

Turn off ajax / don't use remote command!

You only need to make sure that the action method is not called by an ajax request, but that it is called by a normal request as you fire with <h:commandLink> and <h:commandButton>. Ajax requests and remote commands are handled by JavaScript which in turn has, due to security reasons, no facilities to force a Save As dialogue with the content of the ajax response.

In case you're using e.g. PrimeFaces <p:commandXxx>, then you need to make sure that you explicitly turn off ajax via ajax="false" attribute. In case you're using ICEfaces, then you need to nest a <f:ajax disabled="true" /> in the command component.

Generic JSF 2.x example

public void download() throws IOException {
    FacesContext fc = FacesContext.getCurrentInstance();
    ExternalContext ec = fc.getExternalContext();

    ec.responseReset(); // Some JSF component library or some Filter might have set some headers in the buffer beforehand. We want to get rid of them, else it may collide.
    ec.setResponseContentType(contentType); // Check http://www.iana.org/assignments/media-types for all types. Use if necessary ExternalContext#getMimeType() for auto-detection based on filename.
    ec.setResponseContentLength(contentLength); // Set it with the file size. This header is optional. It will work if it's omitted, but the download progress will be unknown.
    ec.setResponseHeader("Content-Disposition", "attachment; filename=\"" + fileName + "\""); // The Save As popup magic is done here. You can give it any file name you want, this only won't work in MSIE, it will use current request URL as file name instead.

    OutputStream output = ec.getResponseOutputStream();
    // Now you can write the InputStream of the file to the above OutputStream the usual way.
    // ...

    fc.responseComplete(); // Important! Otherwise JSF will attempt to render the response which obviously will fail since it's already written with a file and closed.
}

Generic JSF 1.x example

public void download() throws IOException {
    FacesContext fc = FacesContext.getCurrentInstance();
    HttpServletResponse response = (HttpServletResponse) fc.getExternalContext().getResponse();

    response.reset(); // Some JSF component library or some Filter might have set some headers in the buffer beforehand. We want to get rid of them, else it may collide.
    response.setContentType(contentType); // Check http://www.iana.org/assignments/media-types for all types. Use if necessary ServletContext#getMimeType() for auto-detection based on filename.
    response.setContentLength(contentLength); // Set it with the file size. This header is optional. It will work if it's omitted, but the download progress will be unknown.
    response.setHeader("Content-Disposition", "attachment; filename=\"" + fileName + "\""); // The Save As popup magic is done here. You can give it any file name you want, this only won't work in MSIE, it will use current request URL as file name instead.

    OutputStream output = response.getOutputStream();
    // Now you can write the InputStream of the file to the above OutputStream the usual way.
    // ...

    fc.responseComplete(); // Important! Otherwise JSF will attempt to render the response which obviously will fail since it's already written with a file and closed.
}

Common static file example

In case you need to stream a static file from the local disk file system, substitute the code as below:

File file = new File("/path/to/file.ext");
String fileName = file.getName();
String contentType = ec.getMimeType(fileName); // JSF 1.x: ((ServletContext) ec.getContext()).getMimeType(fileName);
int contentLength = (int) file.length();

// ...

Files.copy(file.toPath(), output);

Common dynamic file example

In case you need to stream a dynamically generated file, such as PDF or XLS, then simply provide output there where the API being used expects an OutputStream.

E.g. iText PDF:

String fileName = "dynamic.pdf";
String contentType = "application/pdf";

// ...

Document document = new Document();
PdfWriter writer = PdfWriter.getInstance(document, output);
document.open();
// Build PDF content here.
document.close();

E.g. Apache POI HSSF:

String fileName = "dynamic.xls";
String contentType = "application/vnd.ms-excel";

// ...

HSSFWorkbook workbook = new HSSFWorkbook();
// Build XLS content here.
workbook.write(output);
workbook.close();

Note that you cannot set the content length here. So you need to remove the line to set response content length. This is technically no problem, the only disadvantage is that the enduser will be presented an unknown download progress. In case this is important, then you really need to write to a local (temporary) file first and then provide it as shown in previous chapter.

Utility method

If you're using JSF utility library OmniFaces, then you can use one of the three convenient Faces#sendFile() methods taking either a File, or an InputStream, or a byte[], and specifying whether the file should be downloaded as an attachment (true) or inline (false).

public void download() throws IOException {
    Faces.sendFile(file, true);
}

Yes, this code is complete as-is. You don't need to invoke responseComplete() and so on yourself. This method also properly deals with IE-specific headers and UTF-8 filenames. You can find source code here.

First, unzip the APK and extract the file /META-INF/ANDROID_.RSA (this file may also be CERT.RSA, but there should only be one .RSA file).

Then issue this command:

keytool -printcert -file ANDROID_.RSA

You will get certificate fingerprints like this:

     MD5:  B3:4F:BE:07:AA:78:24:DC:CA:92:36:FF:AE:8C:17:DB
     SHA1: 16:59:E7:E3:0C:AA:7A:0D:F2:0D:05:20:12:A8:85:0B:32:C5:4F:68
     Signature algorithm name: SHA1withRSA

Then use the keytool again to print out all the aliases of your signing keystore:

keytool -list -keystore my-signing-key.keystore

You will get a list of aliases and their certificate fingerprint:

android_key, Jan 23, 2010, PrivateKeyEntry,
Certificate fingerprint (MD5): B3:4F:BE:07:AA:78:24:DC:CA:92:36:FF:AE:8C:17:DB

Voila! we can now determined the apk has been signed with this keystore, and with the alias 'android_key'.

Keytool is part of Java, so make sure your PATH has Java installation dir in it.

Whevever you get a problem like this just go to the man page for the function in question and it will tell you what header you are missing, e.g.

$ man memset

MEMSET(3)                BSD Library Functions Manual                MEMSET(3)

NAME
     memset -- fill a byte string with a byte value

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <string.h>

     void *
     memset(void *b, int c, size_t len);

Note that for C++ it's generally preferable to use the proper equivalent C++ headers, <cstring>/<cstdio>/<cstdlib>/etc, rather than C's <string.h>/<stdio.h>/<stdlib.h>/etc.

As of 2017, an easy method to achieve this is the following:

import ctypes, sys

def is_admin():
    try:
        return ctypes.windll.shell32.IsUserAnAdmin()
    except:
        return False

if is_admin():
    # Code of your program here
else:
    # Re-run the program with admin rights
    ctypes.windll.shell32.ShellExecuteW(None, "runas", sys.executable, " ".join(sys.argv), None, 1)

If you are using Python 2.x, then you should replace the last line for:

ctypes.windll.shell32.ShellExecuteW(None, u"runas", unicode(sys.executable), unicode(" ".join(sys.argv)), None, 1)

Also note that if you converted you python script into an executable file (using tools like py2exe, cx_freeze, pyinstaller) then you should use sys.argv[1:] instead of sys.argv in the fourth parameter.

Some of the advantages here are:

• No external libraries required. It only uses ctypes and sys from standard library.
• Works on both Python 2 and Python 3.
• There is no need to modify the file resources nor creating a manifest file.
• If you don't add code below if/else statement, the code won't ever be executed twice.
• You can get the return value of the API call in the last line and take an action if it fails (code <= 32). Check possible return values here.
• You can change the display method of the spawned process modifying the sixth parameter.

Documentation for the underlying ShellExecute call is here.

In my experience, using a PYTHONPATH variable at all is usually the wrong approach, because it does not play nicely with VENV on windows. PYTHON on loading will prepare the path by prepending PYTHONPATH to the path, which can result in your carefully prepared Venv preferentially fetching global site packages.

Instead of using PYTHON path, include a pythonpath.pth file in the relevant site-packages directory (although beware custom pythons occasionally look for them in different locations, e.g. enthought looks in the same directory as python.exe for its .pth files) with each virtual environment. This will act like a PYTHONPATH only it will be specific to the python installation, so you can have a separate one for each python installation/environment. Pycharm integrates strongly with VENV if you just go to yse the VENV's python as your python installation.

See e.g. this SO question for more details on .pth files....

That tool is part of the setuptools (now called Distribute) package. Install Distribute. Of course you'll have to fetch that one manually.

http://pypi.python.org/pypi/distribute#installation-instructions

It is possible and you don't need to code it on your own.

Just set the ringer volume to zero and vibration to none if incomingNumber equals an empty string. Thats it ...

Its just done for you with the application Nostalk from Android Market. Just give it a try ...

In my case function eval() works very good. Below I generate 10 variables and assign them 10 values.

lhs <- rnorm(10)
rhs <- paste("perf.a", 1:10, "<-", lhs, sep="")
eval(parse(text=rhs))

You can use :

composer self-update --2

To update to 2.0.8 version (Latest stable version)

You're not using splice correctly:

arr.splice(4, 1)

this will remove 1 item at index 4. see here

I think you want to use slice:

arr.slice(0,5)

this will return elements in position 0 through 4.

This assumes all the rest of your code (cookies etc) works correctly

  public Optional<String> InputStreamToBase64(Optional<InputStream> inputStream) throws IOException{
    if (inputStream.isPresent()) {
        ByteArrayOutputStream outpString base64Image = data.split(",")[1];
byte[] imageBytes = javax.xml.bind.DatatypeConverter.parseBase64Binary(base64Image);

Then you can do whatever you like with the bytes like:

BufferedImage img = ImageIO.read(new ByteArrayInputStream(imageBytes));ut = new ByteArrayOutputStream();
        FileCopyUtils.copy(inputStream.get(), output);
        //TODO retrieve content type from file, & replace png below with it
        return Optional.ofNullable("data:image/png;base64," + DatatypeConverter.printBase64Binary(output.toByteArray()));
    }

    return Optional.empty();

You should never use the unidirectional @OneToMany annotation because:

1. It generates inefficient SQL statements
2. It creates an extra table which increases the memory footprint of your DB indexes

Now, in your first example, both sides are owning the association, and this is bad.

While the @JoinColumn would let the @OneToMany side in charge of the association, it's definitely not the best choice. Therefore, always use the mappedBy attribute on the @OneToMany side.

public class User{
    @OneToMany(fetch=FetchType.LAZY, cascade = CascadeType.ALL, mappedBy="user")
    public List<APost> aPosts;

    @OneToMany(fetch=FetchType.LAZY, cascade = CascadeType.ALL, mappedBy="user")
    public List<BPost> bPosts;
}

public class BPost extends Post {

    @ManyToOne(fetch=FetchType.LAZY)    
    public User user;
}

public class APost extends Post {

     @ManyToOne(fetch=FetchType.LAZY) 
     public User user;
}

NSDate *date = [NSDate date];
NSInteger era, year, month, day;
[[NSCalendar currentCalendar] getEra:&era year:&year month:&month day:&day fromDate:date];

If uploading an image, try reducing the image quality, which is the second parameter of the Bitmap. This was the solution in my case. Previously it was 90, then I tried with 60 (as it is in the code below now).

Bitmap yourSelectedImage = BitmapFactory.decodeStream(imageStream);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
finalBitmap.compress(Bitmap.CompressFormat.JPEG,60,baos);
byte[] b = baos.toByteArray();

Try this

-moz-box-shadow:0 5px 5px rgba(182, 182, 182, 0.75);
-webkit-box-shadow: 0 5px 5px rgba(182, 182, 182, 0.75);
box-shadow: 0 5px 5px rgba(182, 182, 182, 0.75);

You can see it in http://jsfiddle.net/wJ7qp/

I know this is a very old question, but here is another sed variation, which may be useful to someone. Unlike some of the others, it only replaces double quotes at the start or end...

echo "$opt" | sed -r 's/^"|"$//g'

you can also use this if you know the name of the primary key

SELECT
    MAX(primary_key_name) + 1
FROM
    TABLE_NAME

APC is going to be included in PHP 6, and I'd guess it has been chosen for good reason :)

It's fairly easy to install and certainly speeds things up.

>>> lst =  ['abcd', 'e', 'fg', 'hijklmn', 'opq', 'r'] 
>>> print [lst[2*i]+lst[2*i+1] for i in range(len(lst)/2)]
['abcde', 'fghijklmn', 'opqr']

Parameters passed to the C program executable is nothing but an array of string(or character pointer),so memory would have been already allocated for these input parameter before your program access these parameters,so no need to allocate buffer,and that way you can avoid error handling code in your program as well(Reduce chances of segfault :)).

echo "mydir/doc/ mydir/usoe ./mydir/usm" |  awk '{ split($0,array," "); for(i in array){ system("cd "array[i]" && echo $PWD") } }'

You can try below query,

select * from players
where 
    us_reg_date between '2000-07-05'
and
    DATE_ADD('2011-11-10',INTERVAL 1 DAY)

In general, there is no way to know when something on another site has been changed. If the site offers an RSS feed, you should try that. If the site does not offer an RSS feed (or if the RSS feed doesn't include the information you're looking for), then you have to scrape and compare.

I have tested the following regex which gives the same result as Chrome Html email input validation.

[a-z0-9!#$%&'*+\/=?^_`{|}~.-]+@[a-z0-9-]+(\.[a-z0-9-]+)*

You can test it out on this website: regex101

If you want to remove duplicates from ArrayList means find the below logic,

public static Object[] removeDuplicate(Object[] inputArray)
{
    long startTime = System.nanoTime();
    int totalSize = inputArray.length;
    Object[] resultArray = new Object[totalSize];
    int newSize = 0;
    for(int i=0; i<totalSize; i++)
    {
        Object value = inputArray[i];
        if(value == null)
        {
            continue;
        }

}

Here, add this line to .zshrc:

export PATH=/home/david/pear/bin:$PATH

EDIT: This does work, but ony's answer below is better, as it takes advantage of the structured interface ZSH provides for variables like $PATH. This approach is standard for bash, but as far as I know, there is no reason to use it when ZSH provides better alternatives.

I had a similar-looking problem after adding a directory tree which contained .svn directories (because it was an svn:external in its source environment): svn status told me "?", but when trying to add it, it was "already under version control".

Since no other versioned directories were present, I did

find . -mindepth 2 -name '.svn' -exec rm -rf '{}' \;

to remove the wrong .svn directories; after doing this, I was able to add the new directory.

Note:

• If other versioned directories are contained, the find expression must be changed to be more specific
• If unsure, first omit the "-exec ..." part to see what would be deleted

ser.read(64) should be ser.read(size=64); ser.read uses keyword arguments, not positional.

Also, you're reading from the port twice; what you probably want to do is this:

i=0
for modem in PortList:
    for port in modem:
        try:
            ser = serial.Serial(port, 9600, timeout=1)
            ser.close()
            ser.open()
            ser.write("ati")
            time.sleep(3)
            read_val = ser.read(size=64)
            print read_val
            if read_val is not '':
                print port
        except serial.SerialException:
            continue
        i+=1

you can do it by following way too ..

create table #test (a int, b char(1))

select * From #test

exec tempdb..sp_columns '#test'

I have an easier solution using fs.readFileSync(./my_local_image_path.jpg)

This is for reading images from Azure Cognative Services's Vision API

const subscriptionKey = 'your_azure_subscrition_key';
const uriBase = // **MUST change your location (mine is 'eastus')**
    'https://eastus.api.cognitive.microsoft.com/vision/v2.0/analyze';

// Request parameters.
const params = {
    'visualFeatures': 'Categories,Description,Adult,Faces',
    'maxCandidates': '2',
    'details': 'Celebrities,Landmarks',
    'language': 'en'
};

const options = {
    uri: uriBase,
    qs: params,
    body: fs.readFileSync(./my_local_image_path.jpg),
    headers: {
        'Content-Type': 'application/octet-stream',
        'Ocp-Apim-Subscription-Key' : subscriptionKey
    }
};

request.post(options, (error, response, body) => {
if (error) {
    console.log('Error: ', error);
    return;
}
let jsonString = JSON.stringify(JSON.parse(body), null, '  ');
body = JSON.parse(body);
if (body.code) // err
{
    console.log("AZURE: " + body.message)
}

console.log('Response\n' + jsonString);

There is a JDK dropdown in "job name" -> Configure in Jenkins web ui. It will list all JDKs available in Jenkins configuration.

In my case, I had a textbox that was attached to a datepicker. The only solution that worked for me was to handle it inside the onSelect event of the datepicker.

<input type="text"  id="bookdate">

$("#bookdate").datepicker({            
     onSelect: function (selected) {
         //handle change event here
     }
});

A simple utility function for both id and class selector.

function exist(IdOrClassName, IsId) {
  var elementExit = false;
  if (IsId) {
    elementExit = $("#" + "" + IdOrClassName + "").length ? true : false;
  } else {
    elementExit = $("." + "" + IdOrClassName + "").length ? true : false;
  }
  return elementExit;
}

calling this function like bellow

$(document).ready(function() {
  $("#btnCheck").click(function() {
    //address is the id so IsId is true. if address is class then need to set IsId false
    if (exist("address", true)) {
      alert("exist");
    } else {
      alert("not exist");
    }
  });
});

In C++, you can use a such function:

template <typename T>
T to(const std::string & s)
{
    std::istringstream stm(s);
    T result;
    stm >> result;

    if(stm.tellg() != s.size())
        throw error;

    return result;
}

This can help you to convert any string to any type such as float, int, double...

There is a typo in your SQL. Fixed version is below:

SELECT GETVARIABLE('SYSIBM.VERSION') FROM SYSIBM.SYSDUMMY1;

I ran this on the IBM Mainframe under Z/OS in QMF and got the following results. We are currently running DB2 Version 8 and upgrading to Ver 10.

DSN08015  -- Format seems to be DSNVVMMM
-- PPP IS PRODUCT STRING 'DSN'
-- VV IS VERSION NUMBER E.G. 08
-- MMM IS MAINTENANCE LEVEL E.G. 015

Not really, you have to assign a variable. So

    var bar = Stuff.Elements.Foo;
    bar.Name = "Bob Dylan";
    bar.Age = 68;
    bar.Location = "On Tour";
    bar.IsCool = True;

Or in C# 3.0:

    var bar = Stuff.Elements.Foo
    {
        Name = "Bob Dylan",
        Age = 68,
        Location = "On Tour",
        IsCool = True
    };

Use "%%". The man page describes this requirement:

% A '%' is written. No argument is converted. The complete conversion specification is '%%'.

If you use eg. "id" you can do it this way:

   (function() {_x000D_
    let x = document.getElementById("idName");_x000D_
    let y = document.getElementById("liName");_x000D_
    _x000D_
    y.addEventListener('click', function(e) {_x000D_
        y.appendChild(x);_x000D_
    });_x000D_
_x000D_
  _x000D_
})();

Time 30 minutes later

$newTime = date("Y-m-d H:i:s",strtotime(date("Y-m-d H:i:s")." +30 minutes"))

If you want just the summary of the exception use:

    try
    {
        test();
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message);
    }

If you want to see the whole stack trace (usually better for debugging) use:

    try
    {
        test();
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.ToString());
    }

Another method I sometime use is:

    private DoSomthing(int arg1, int arg2, out string errorMessage)
    {
         int result ;
        errorMessage = String.Empty;
        try 
        {           
            //do stuff
            int result = 42;
        }
        catch (Exception ex)
        {

            errorMessage = ex.Message;//OR ex.ToString(); OR Free text OR an custom object
            result = -1;
        }
        return result;
    }

And In your form you will have something like:

    string ErrorMessage;
    int result = DoSomthing(1, 2, out ErrorMessage);
    if (!String.IsNullOrEmpty(ErrorMessage))
    {
        MessageBox.Show(ErrorMessage);
    }

There is a bit of a contradiction in the question's title and the content. The title speaks of a parent div, but the question makes it sound like you want two sibling divs (navigation and content) to be the same height.

Do you (a) want both navigation and content to be 100% the height of main, or (b) want navigation and content to be be same height?

I'll assume (b)...if that is so, I don't think you will be able to do it given your current page structure (at least, not with pure CSS and no scripting). You would probably need to do something like:

<main div>
    <content div>
         <navigation div></div>
    </div>
</div>

and set the content div to have a left margin of whatever the width of the navigation pane is. That way, the content's content is to the right of the navigation and you can set the navigation div to be 100% of the content's height.

EDIT: I'm doing this completely in my head, but you would probably also need to set the navigation div's left margin to a negative value or set it's absolute left to 0 to shove it back to the far left. Problem is, there are many ways to pull this off but not all of them are going to be compatible with all browsers.

I also found that the unit test code should put under the test folder, it can not be recognized as test class if you put it under the main folder. eg.

Wrong

/my_program/src/main/java/NotTest.java

Right

/my_program/src/test/java/MyTest.java

Sure it is OK. Actually you can see for yourself easily:

l = range(12000)
l = sorted(l, reverse=True)

Running the those lines on my machine took:

real    0m0.036s
user    0m0.024s
sys  0m0.004s

But sure as everyone else said. The larger the array the slower the operations will be.

Many answers using external programs, which is not really using Bash.

If you know you will have Bash4 available you should really just use the ${VAR,,} notation (it is easy and cool). For Bash before 4 (My Mac still uses Bash 3.2 for example). I used the corrected version of @ghostdog74 's answer to create a more portable version.

One you can call lowercase 'my STRING' and get a lowercase version. I read comments about setting the result to a var, but that is not really portable in Bash, since we can't return strings. Printing it is the best solution. Easy to capture with something like var="$(lowercase $str)".

How this works

The way this works is by getting the ASCII integer representation of each char with printf and then adding 32 if upper-to->lower, or subtracting 32 if lower-to->upper. Then use printf again to convert the number back to a char. From 'A' -to-> 'a' we have a difference of 32 chars.

Using printf to explain:

$ printf "%d\n" "'a"
97
$ printf "%d\n" "'A"
65

97 - 65 = 32

And this is the working version with examples.
Please note the comments in the code, as they explain a lot of stuff:

#!/bin/bash

# lowerupper.sh

# Prints the lowercase version of a char
lowercaseChar(){
    case "$1" in
        [A-Z])
            n=$(printf "%d" "'$1")
            n=$((n+32))
            printf \\$(printf "%o" "$n")
            ;;
        *)
            printf "%s" "$1"
            ;;
    esac
}

# Prints the lowercase version of a sequence of strings
lowercase() {
    word="$@"
    for((i=0;i<${#word};i++)); do
        ch="${word:$i:1}"
        lowercaseChar "$ch"
    done
}

# Prints the uppercase version of a char
uppercaseChar(){
    case "$1" in
        [a-z])
            n=$(printf "%d" "'$1")
            n=$((n-32))
            printf \\$(printf "%o" "$n")
            ;;
        *)
            printf "%s" "$1"
            ;;
    esac
}

# Prints the uppercase version of a sequence of strings
uppercase() {
    word="$@"
    for((i=0;i<${#word};i++)); do
        ch="${word:$i:1}"
        uppercaseChar "$ch"
    done
}

# The functions will not add a new line, so use echo or
# append it if you want a new line after printing

# Printing stuff directly
lowercase "I AM the Walrus!"$'\n'
uppercase "I AM the Walrus!"$'\n'

echo "----------"

# Printing a var
str="A StRing WITH mixed sTUFF!"
lowercase "$str"$'\n'
uppercase "$str"$'\n'

echo "----------"

# Not quoting the var should also work, 
# since we use "$@" inside the functions
lowercase $str$'\n'
uppercase $str$'\n'

echo "----------"

# Assigning to a var
myLowerVar="$(lowercase $str)"
myUpperVar="$(uppercase $str)"
echo "myLowerVar: $myLowerVar"
echo "myUpperVar: $myUpperVar"

echo "----------"

# You can even do stuff like
if [[ 'option 2' = "$(lowercase 'OPTION 2')" ]]; then
    echo "Fine! All the same!"
else
    echo "Ops! Not the same!"
fi

exit 0

And the results after running this:

$ ./lowerupper.sh 
i am the walrus!
I AM THE WALRUS!
----------
a string with mixed stuff!
A STRING WITH MIXED STUFF!
----------
a string with mixed stuff!
A STRING WITH MIXED STUFF!
----------
myLowerVar: a string with mixed stuff!
myUpperVar: A STRING WITH MIXED STUFF!
----------
Fine! All the same!

This should only work for ASCII characters though.

For me it is fine, since I know I will only pass ASCII chars to it.
I am using this for some case-insensitive CLI options, for example.

Unfortunately, detecting pinch gestures across browsers is a not as simple as one would hope, but HammerJS makes it a lot easier!

Check out the Pinch Zoom and Pan with HammerJS demo. This example has been tested on Android, iOS and Windows Phone.

The current way to do this is by using the "Add Service Reference" command. If you specify "TestUploaderWebService" as the service reference name, that will generate the type TestUploaderWebService.Service1. That class will have a method named GetFileListOnWebServer, which will return an array of strings (you can change that to be a list of strings if you like). You would use it like this:

string[] files = null;
TestUploaderWebService.Service1 proxy = null;
bool success = false;
try
{
    proxy = new TestUploaderWebService.Service1();
    files = proxy.GetFileListOnWebServer();
    proxy.Close();
    success = true;
}
finally
{
    if (!success)
    {
        proxy.Abort();
    }
}

P.S. Tell your instructor to look at "Microsoft: ASMX Web Services are a “Legacy Technology”", and ask why he's teaching out of date technology.

Just use an <a> by itself, set it to display: block; and set width and height. Get rid of the <span> and <div>. This is the semantic way to do it. There is no need to wrap things in <divs> (or any element) for layout. That is what CSS is for.

Demo: http://jsfiddle.net/ThinkingStiff/89Enq/

HTML:

<a id="music" href="Music.html">Music I Like</a>

CSS:

#music {
    background-color: black;
    color: white;
    display: block;
    height: 40px;
    line-height: 40px;
    text-decoration: none;
    width: 100px;
    text-align: center;
}

I believe you can find out Eclipse Platform version for every software product that is Eclipse-based.

1. Open Installation Details:

   • Go to Help => About => Installation Details.
   • Or to Help => Install New Software... => click What is already installed? link.

2. Choose Plug-ins tab => type org.eclipse.platform => check Version column.

3. You can match version code and version name on https://wiki.eclipse.org/Older_Versions_Of_Eclipse

For example, check out GitEye (Git GUI client)

Or checkout DBBeaver (DB manager):

change_column_default :employees, :foreign, false

I assume that you haven't set the TableName property of the DataTable, for example via constructor:

var tbl = new DataTable("dtImage");

If you don't provide a name, it will be automatically created with "Table1", the next table will get "Table2" and so on.

Then the solution would be to provide the TableName and then check with Contains(nameOfTable).

To clarify it: You'll get an ArgumentException if that DataTable already belongs to the DataSet (the same reference). You'll get a DuplicateNameException if there's already a DataTable in the DataSet with the same name(not case-sensitive).

Try remove_missing instead with vars = the_variable. It is very important that you set the vars argument, otherwise remove_missing will remove all rows that contain an NA in any column!! Setting na.rm = TRUE will suppress the warning message.

ggplot(data = remove_missing(MyData, na.rm = TRUE, vars = the_variable),aes(x= the_variable, fill=the_variable, na.rm = TRUE)) + 
       geom_bar(stat="bin") 

The syntax for ng if else in angular is :

    data-ng-model="customizationCntrl.check[data.id1]" data-ng-checked="
    {{data.status}}=='1'" onclick="return false;">{{data.displayName}}<br>
</div>
<ng-template #elsepart>
    <div class="case">
        <input type="checkbox" id="{{data.id}}" value={{data.displayName}}"

I couldn't uninstall WebDav from my Server because I didn't have admin privileges. Also, sometimes I was getting the method not allowed on .css and .js files. In the end, with the configuration above set up everything started working again.

ByteArrayInputStream extends InputStream:

You may need read this https://developer.android.com/guide/topics/resources/drawable-resource.html#Shape

and below there is a Note.

Note Every corner must (initially) be provided a corner radius greater than 1, or else no corners are rounded. If you want specific corners to not be rounded, a work-around is to use android:radius to set a default corner radius greater than 1, but then override each and every corner with the values you really want, providing zero ("0dp") where you don't want rounded corners.

The problem may be that ssh is trying to connect to all the different IPs that www.google.com resolves to. For example on my machine:

# ssh -v -o ConnectTimeout=1 -o ConnectionAttempts=1 www.google.com
OpenSSH_5.9p1, OpenSSL 0.9.8t 18 Jan 2012
debug1: Connecting to www.google.com [173.194.43.20] port 22.

debug1: Connecting to www.google.com [173.194.43.19] port 22.
debug1: connect to address 173.194.43.19 port 22: Connection timed out
debug1: Connecting to www.google.com [173.194.43.18] port 22.
debug1: connect to address 173.194.43.18 port 22: Connection timed out
debug1: Connecting to www.google.com [173.194.43.17] port 22.
debug1: connect to address 173.194.43.17 port 22: Connection timed out
debug1: Connecting to www.google.com [173.194.43.16] port 22.
debug1: connect to address 173.194.43.16 port 22: Connection timed out
ssh: connect to host www.google.com port 22: Connection timed out

If I run it with a specific IP, it returns much faster.

EDIT: I've timed it (with time) and the results are:

• www.google.com - 5.086 seconds
• 173.94.43.16 - 1.054 seconds

var x = parseInt(455/10);

The parseInt() function parses a string and returns an integer.

The radix parameter is used to specify which numeral system to be used, for example, a radix of 16 (hexadecimal) indicates that the number in the string should be parsed from a hexadecimal number to a decimal number.

If the radix parameter is omitted, JavaScript assumes the following:

If the string begins with "0x", the radix is 16 (hexadecimal)
If the string begins with "0", the radix is 8 (octal). This feature is deprecated
If the string begins with any other value, the radix is 10 (decimal)

You can use DataSet.Tables(0).Columns.Contains(name) to check whether the DataTable contains a column with a particular name.

I hope this will helps others too

The solution is very simple if we consider the type of the constant value, which should be "unsigned int" instead of "int".

Instead of:

setval(0)

Use:

setval(0u)

The suffix "u" tell the compiler this is a unsigned integer. Then, no conversion would be needed, and the call will be unambiguous.

For anyone reading this who is using EclipseLink for JPA 2.0, here are the two annotations I had to use to get JPA to persist data, where "MySequenceGenerator" is whatever name you want to give the generator, "myschema" is the name of the schema in your database that contains the sequence object, and "mysequence" is the name of the sequence object in the database.

@GeneratedValue(strategy= GenerationType.SEQUENCE, generator="MySequenceGenerator")
@SequenceGenerator(allocationSize=1, schema="myschema",  name="MySequenceGenerator", sequenceName = "mysequence")

For those using EclipseLink (and possibly other JPA providers), it is CRITICAL that you set the allocationSize attribute to match the INCREMENT value defined for your sequence in the database. If you don't, you'll get a generic persistence failure, and waste a good deal of time trying to track it down, like I did. Here is the reference page that helped me overcome this challenge:

http://wiki.eclipse.org/EclipseLink/Examples/JPA/PrimaryKey#Using_Sequence_Objects

Also, to give context, here is what we're using:

Java 7 Glassfish 3.1 PostgreSQL 9.1 PrimeFaces 3.2/JSF 2.1

Also, for laziness' sake, I built this in Netbeans with the wizards for generating Entities from DB, Controllers from Entities, and JSF from Entities, and the wizards (obviously) do not know how to deal with sequence-based ID columns, so you'll have to manually add these annotations.

You are doing mistake in "configuration_page.jsp" file. here in this file , function loadXMLDoc() 's line number 2 should be like this:

var config=document.getElementsByName('configselect').value;

because you have declared only the name attribute in your <select> tag. So you should get this element by name.

After correcting this, it will run without any JavaScript error

Other answers suggest how to get a floating-point value. While this wlil be close to what you want, it won't be exact:

>>> 0.4/100.
0.0040000000000000001

If you actually want a decimal value, do this:

>>> import decimal
>>> decimal.Decimal('4') / decimal.Decimal('100')
Decimal("0.04")

That will give you an object that properly knows that 4 / 100 in base 10 is "0.04". Floating-point numbers are actually in base 2, i.e. binary, not decimal.

It may be relevant to see if it's running in PHP via command line as well-

<path-to-php-binary>php -i | grep memcache

I faced the same issue as the author of the question. For our case answers in this question weren't enough since each of the members of my team had a different local environment and we definitely needed to .gitignore the file that had the different db connection string and credentials, so people don't commit the common file by mistake and break others' db connections.

On top of that when we followed the procedure below it was easy to deploy on different environments and as en extra bonus we didn't need to have any sensitive information in the version control at all.

Getting the idea from PHP Symfony 3 framework that has a parameters.yml (.gitignored) and a parameters.yml.dist (which is a sample that creates the first one through composer install),

I did the following combining the knowledge from answers below: https://stackoverflow.com/a/35534970/986160 and https://stackoverflow.com/a/35535138/986160.

Essentially this gives the freedom to use inheritance of spring configurations and choose active profiles through configuration at the top one plus any extra sensitive credentials as follows:

Same can be done with .properties

Static variable retains it's previous value until the program exit. Static is used by calling directly class_Name.Method() or class_Name.Property. No object reference is needed. The most popular use of static is C#'s Math class. Math.Sin(), Math.Cos(), Math.Sqrt().

In case anyone is still struggling with this, as I was all morning today, I have found a solution that works for me:

Uncompyle

Installation instructions:

git clone https://github.com/gstarnberger/uncompyle.git
cd uncompyle/
sudo ./setup.py install

Once the program is installed (note: it will be installed to your system-wide-accessible Python packages, so it should be in your $PATH), you can recover your Python files like so:

uncompyler.py thank_goodness_this_still_exists.pyc > recovered_file.py

The decompiler adds some noise mostly in the form of comments, however I've found it to be surprisingly clean and faithful to my original code. You will have to remove a little line of text beginning with +++ near the end of the recovered file to be able to run your code.

void ul2chardec(char*pcIP, unsigned long ulIPN){
int i; int k=0; char c0, c1;
for (i = 0; i<4; i++){
    c0 = ((((ulIPN & (0xff << ((3 - i) * 8))) >> ((3 - i) * 8))) / 100) + 0x30;
    if (c0 != '0'){ *(pcIP + k) = c0; k++; }
    c1 = (((((ulIPN & (0xff << ((3 - i) * 8))) >> ((3 - i) * 8))) % 100) / 10) + 0x30;
    if (!(c1 =='0' && c0=='0')){ *(pcIP + k) = c1; k++; }
    *(pcIP +k) = (((((ulIPN & (0xff << ((3 - i) * 8)))) >> ((3 - i) * 8))) % 10) + 0x30;
    k++;
    if (i<3){ *(pcIP + k) = '.'; k++;}
}
*(pcIP + k) = 0; // pcIP should be x10 bytes

}

If you bind events to the onmouseover and onmouseout events in Jquery, you can then trigger that effect using mouseenter().

What are you trying to accomplish?

If you see an out of memory, consider if that is plausible: Do you really need that much memory? If not (i.e. when you don't have huge objects and if you don't need to create millions of objects for some reason), chances are that you have a memory leak.

In Java, this means that you're keeping a reference to an object somewhere even though you don't need it anymore. Common causes for this is forgetting to call close() on resources (files, DB connections, statements and result sets, etc.).

If you suspect a memory leak, use a profiler to find which object occupies all the available memory.

Small addition to @user995502's answer on how to run the program.

g++ player.cpp main.cpp -o main.out && ./main.out

One requirement for remote debugging is that the windows account used to run SSMS be part of the sysadmin role. See this MSDN link: http://msdn.microsoft.com/en-us/library/cc646024%28v=sql.105%29.aspx

Cloud: the hardware running the application scales to meet the demand (potentially crossing multiple machines, networks, etc).

Grid: the application scales to take as much hardware as possible (for example in the hope of finding extra-terrestrial intelligence).

Cluster: this is an old term referring to one OS instance or one DB instance installed across multiple machines. It was done with special OS handling, proprietary drivers, low latency network cards with fat cables, and various hardware bedfellows.

(We love you SGI, but notice that "Cloud" and "Grid" are available to the little guy and your NUMAlink never has been...)

You can do it with a table, like this:

<table width="100%">
  <tr>
    <td style="width: 50%">Left Text</td>
    <td style="width: 50%; text-align: right;">Right Text</td>
  </tr>
</table>

Or, you can do it with CSS like this:

<div style="float: left;">
    Left text
</div>
<div style="float: right;">
    Right text
</div>

The compile() method is always called at some point; it's the only way to create a Pattern object. So the question is really, why should you call it explicitly? One reason is that you need a reference to the Matcher object so you can use its methods, like group(int) to retrieve the contents of capturing groups. The only way to get ahold of the Matcher object is through the Pattern object's matcher() method, and the only way to get ahold of the Pattern object is through the compile() method. Then there's the find() method which, unlike matches(), is not duplicated in the String or Pattern classes.

The other reason is to avoid creating the same Pattern object over and over. Every time you use one of the regex-powered methods in String (or the static matches() method in Pattern), it creates a new Pattern and a new Matcher. So this code snippet:

for (String s : myStringList) {
    if ( s.matches("\\d+") ) {
        doSomething();
    }
}

...is exactly equivalent to this:

for (String s : myStringList) {
    if ( Pattern.compile("\\d+").matcher(s).matches() ) {
        doSomething();
    }
}

Obviously, that's doing a lot of unnecessary work. In fact, it can easily take longer to compile the regex and instantiate the Pattern object, than it does to perform an actual match. So it usually makes sense to pull that step out of the loop. You can create the Matcher ahead of time as well, though they're not nearly so expensive:

Pattern p = Pattern.compile("\\d+");
Matcher m = p.matcher("");
for (String s : myStringList) {
    if ( m.reset(s).matches() ) {
        doSomething();
    }
}

If you're familiar with .NET regexes, you may be wondering if Java's compile() method is related to .NET's RegexOptions.Compiled modifier; the answer is no. Java's Pattern.compile() method is merely equivalent to .NET's Regex constructor. When you specify the Compiled option:

Regex r = new Regex(@"\d+", RegexOptions.Compiled); 

...it compiles the regex directly to CIL byte code, allowing it to perform much faster, but at a significant cost in up-front processing and memory use--think of it as steroids for regexes. Java has no equivalent; there's no difference between a Pattern that's created behind the scenes by String#matches(String) and one you create explicitly with Pattern#compile(String).

(EDIT: I originally said that all .NET Regex objects are cached, which is incorrect. Since .NET 2.0, automatic caching occurs only with static methods like Regex.Matches(), not when you call a Regex constructor directly. ref)

The following method works perfectly for me, so here's my full implementation:

<img id="my_image" style="display: none;" src="my.png" width="924" height="330" border="0" usemap="#map" />

<map name="map" id="map">
    <area shape="poly" coords="774,49,810,21,922,130,920,222,894,212,885,156,874,146" href="#mylink" />
    <area shape="poly" coords="649,20,791,157,805,160,809,217,851,214,847,135,709,1,666,3" href="#myotherlink" />
</map>

<script>
$(function(){
    var image_is_loaded = false;
    $("#my_image").on('load',function() {
        $(this).data('width', $(this).attr('width')).data('height', $(this).attr('height'));
        $($(this).attr('usemap')+" area").each(function(){
            $(this).data('coords', $(this).attr('coords'));
        });

        $(this).css('width', '100%').css('height','auto').show();

        image_is_loaded = true;
        $(window).trigger('resize');
    });


    function ratioCoords (coords, ratio) {
        coord_arr = coords.split(",");

        for(i=0; i < coord_arr.length; i++) {
            coord_arr[i] = Math.round(ratio * coord_arr[i]);
        }

        return coord_arr.join(',');
    }
    $(window).on('resize', function(){
        if (image_is_loaded) {
            var img = $("#my_image");
            var ratio = img.width()/img.data('width');

            $(img.attr('usemap')+" area").each(function(){
                console.log('1: '+$(this).attr('coords'));
                $(this).attr('coords', ratioCoords($(this).data('coords'), ratio));
            });
        }
    });
});
</script>

Verified: it works well in Docker 1.7.0.

Don't specify --pull=true when running the docker build command

From this thread on reference locally-built image using FROM at dockerfile:

If you want use the local image as the base image, pass without the option --pull=true
--pull=true will always attempt to pull a newer version of the image.

here is a method to point

sh -> bash

run this command on terminal

sudo dpkg-reconfigure dash

After this you should see

ls -l /bin/sh

point to /bin/bash (and not to /bin/dash)

Reference

Important update (Python 3.4):

Any identifier of the form __name (at least two leading underscores, at most one trailing underscore) is publicly replaced with _classname__name, where classname is the current class name with leading underscore(s) stripped.

Therefore, __name is private, while _classname__name is public.

https://docs.python.org/3/tutorial/classes.html#tut-private

Example

class Cat:
    def __init__(self, name='unnamed'):
        self.name = name
    def __print_my_name(self):
        print(self.name)
        
        
tom = Cat()
tom.__print_my_name() #Error
tom._Cat__print_my_name() #Prints name

I think you've got the most efficient way

def shift(l,n):
    n = n % len(l)  
    return l[-U:] + l[:-U]

You can use the onload="" HTML attribute and use JavaScript to adjust the opacity style of your element.

Leave your CSS as you proposed. Edit your HTML code to:

<body onload="document.getElementById(test).style.opacity='1'">
    <div id="test">
        <p>?This is a test</p>
    </div>
</body>

This also works to fade-in the complete page when finished loading:

HTML:

<body onload="document.body.style.opacity='1'">
</body>

CSS:

body{ 
    opacity: 0;
    transition: opacity 2s;
    -webkit-transition: opacity 2s; /* Safari */
}

Check the W3Schools website: transitions and an article for changing styles with JavaScript.

All answers above are correct, However People who are coming from other programming language. The easiest approach to follow will be.

variable = 1

print("length " + format(variable))

If you really want to get the type by name you may use the following:

System.AppDomain.CurrentDomain.GetAssemblies().SelectMany(x => x.GetTypes()).First(x => x.Name == "theassembly");

Note that you can improve the performance of this drastically the more information you have about the type you're trying to load.

You could try using UpdateVersion by Matt Griffith. It's quite old now, but works well. To use it, you simply need to setup a pre-build event which points at your AssemblyInfo.cs file, and the application will update the version numbers accordingly, as per the command line arguments.

As the application is open-source, I've also created a version to increment the version number using the format (Major version).(Minor version).([year][dayofyear]).(increment). I've put the code for my modified version of the UpdateVersion application on GitHub: https://github.com/munr/UpdateVersion

New Function and apply() together works also

var a=new Function('alert(1);')
a.apply(null)

In my case, passing responsive: false under options solved the problem. I'm not sure why everybody is telling you to do the opposite, especially since true is the default.

There is a way to SELECT NOTHING that solve your problem.

1. Create a shape (one rectangle)
2. Name it in Shapes Database >>> for example: "Ready"
3. Refer to it MYDOC.Shapes("Ready") and change the visibility to False

When you want that Excel SELECT NOTHING do it:

MYDOC.Shapes("Ready").visible=True
MYDOC.Shapes("Ready").Select
MYDOC.Shapes("Ready").visible=False

This HIDE the selection and nothing still selected in your window PLUS: The word "Ready" is shown at the Left Top in your Sheet.

Put all the 6 classes to 6 different projects. Then create jar files of all the 6 projects. In this manner you will get 6 executable jar files.

Preferred way to change the appearance/whatever of row views once the ListView is drawn is to change something in the data ListView draws from (the array of objects that is passed into your Adapter) and make sure to account for that in your getView() function, then redraw the ListView by calling

notifyDataSetChanged();

EDIT: while there is a way to do this, if you need to do this chances are doing something wrong. While are few edge cases I can think about, generally using notifyDataSetChanged() and other built in mechanisms is a way to go.

EDIT 2: One of the common mistakes people make is trying to come up with their own way to respond to user clicking/selecting a row in the ListView, as in one of the comments to this post. There is an existing way to do this. Here's how:

mListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    /* Parameters
    parent:     The AdapterView where the click happened.
    view:       The view within the AdapterView that was clicked (this will be a view provided by the adapter)
    position:   The position of the view in the adapter.
    id:         The row id of the item that was clicked. */
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        //your code here
    }
});

ListView has a lot of build-in functionality and there is no need to reinvent the wheel for simpler cases. Since ListView extends AdapterView, you can set the same Listeners, such as OnItemClickListener as in the example above.

I'm obviosly not a very good R coder, but if you wanted to do this with ggplot2:

data<- rbind(c(480, 780, 431, 295, 670, 360,  190),
             c(720, 350, 377, 255, 340, 615,  345),
             c(460, 480, 179, 560,  60, 735, 1260),
             c(220, 240, 876, 789, 820, 100,   75))

a <- cbind(data[, 1], 1, c(1:4))
b <- cbind(data[, 2], 2, c(1:4))
c <- cbind(data[, 3], 3, c(1:4))
d <- cbind(data[, 4], 4, c(1:4))
e <- cbind(data[, 5], 5, c(1:4))
f <- cbind(data[, 6], 6, c(1:4))
g <- cbind(data[, 7], 7, c(1:4))

data           <- as.data.frame(rbind(a, b, c, d, e, f, g))
colnames(data) <-c("Time", "Type", "Group")
data$Type      <- factor(data$Type, labels = c("A", "B", "C", "D", "E", "F", "G"))

library(ggplot2)

ggplot(data = data, aes(x = Type, y = Time, fill = Group)) + 
       geom_bar(stat = "identity") +
       opts(legend.position = "none")

In C#/.NET 3.5 you could write a little program to do:

using (PrincipalContext context = new PrincipalContext(ContextType.Domain))
{
    string controller = context.ConnectedServer;
    Console.WriteLine( "Domain Controller:" + controller );
} 

This will list all the users in the current domain:

using (PrincipalContext context = new PrincipalContext(ContextType.Domain))
{
    using (UserPrincipal searchPrincipal = new UserPrincipal(context))
    {
       using (PrincipalSearcher searcher = new PrincipalSearcher(searchPrincipal))
       {
           foreach (UserPrincipal principal in searcher.FindAll())
           {
               Console.WriteLine( principal.SamAccountName);
           }
       }
    }
}

Why not use: CopyOnWriteArraySet from java.util.concurrent?

If you are interested in only selecting one column this will work.

df[["item1"]].to_dict("records")

The below will NOT work and produces a TypeError: unsupported type: . I believe this is because it is trying to convert a series to a dict and not a Data Frame to a dict.

df["item1"].to_dict("records")

I had a requirement to only select one column and convert it to a list of dicts with the column name as the key and was stuck on this for a bit so figured I'd share.

I prefer to use the FindItem method and use the value path for locating the item. Make sure your PathSeparator property on the menu matches what you're using in FindItem parameter.

    protected void Page_Load(object sender, EventArgs e)
    {

        // remove manage user accounts menu item for non-admin users.
        if (!Page.User.IsInRole("Admin"))
        {
            MenuItem item = NavigationMenu.FindItem("Users/Manage Accounts");
            item.Parent.ChildItems.Remove(item);  
        }

    }

The chapter on CAST and CONVERT on MSDN Books Online, you've missed the right answer by one line.... you can use style no. 121 (ODBC canonical (with milliseconds)) to get the result you're looking for:

SELECT CONVERT(VARCHAR(30), GETDATE(), 121)

This gives me the output of:

2012-04-14 21:44:03.793

Update: based on your updated question - of course this won't work - you're converting a string (this: '4/14/2012 2:44:01 PM' is just a string - it's NOT a datetime!) to a string......

You need to first convert the string you have to a DATETIME and THEN convert it back to a string!

Try this:

SELECT CONVERT(VARCHAR(30), CAST('4/14/2012 2:44:01 PM' AS DATETIME), 121) 

Now you should get:

2012-04-14 14:44:01.000

All zeroes for the milliseconds, obviously, since your original values didn't include any ....

I know this is an old question but it does not yet appear to have an answer. I've duplicated this situation, but I'm writing the server app, so I've been able to establish what happens on the server side as well. The client sends the certificate when the server asks for it and if it has a reference to a real certificate in the s_client command line. My server application is set up to ask for a client certificate and to fail if one is not presented. Here is the command line I issue:

Yourhostname here -vvvvvvvvvv s_client -connect <hostname>:443 -cert client.pem -key cckey.pem -CAfile rootcert.pem -cipher ALL:!ADH:!LOW:!EXP:!MD5:@STRENGTH -tls1 -state

When I leave out the "-cert client.pem" part of the command the handshake fails on the server side and the s_client command fails with an error reported. I still get the report "No client certificate CA names sent" but I think that has been answered here above.

The short answer then is that the server determines whether a certificate will be sent by the client under normal operating conditions (s_client is not normal) and the failure is due to the server not recognizing the CA in the certificate presented. I'm not familiar with many situations in which two-way authentication is done although it is required for my project.

You are clearly sending a certificate. The server is clearly rejecting it.

The missing information here is the exact manner in which the certs were created and the way in which the provider loaded the cert, but that is probably all wrapped up by now.

This can be easily done by using enumerate function

code-

lst=[1,2,3,4,1,6,7,9,10,1,2]
for index,item in enumerate(lst):
    if item==1:
        lst[index]=10 #Replaces the item '1' in list with '10'

print(lst)

You could always follow the official guide on how to install Android Studio on Linux. There's even a video you can watch!

https://developer.android.com/studio/install.html

Remember to select Linux in the drop-down box.

To summarise the steps: download Android Studio and extract it and execute studio.sh to run it. If you're running 64-bit Ubuntu, you will need to run:

sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0 lib32stdc++6

In order to understand the use of curly braces in import statements, first, you have to understand the concept of destructuring introduced in ES6

1. Object destructuring

   var bodyBuilder = {
     firstname: 'Kai',
     lastname: 'Greene',
     nickname: 'The Predator'
   };
   
   var {firstname, lastname} = bodyBuilder;
   console.log(firstname, lastname); // Kai Greene
   
   firstname = 'Morgan';
   lastname = 'Aste';
   
   console.log(firstname, lastname); // Morgan Aste
   

2. Array destructuring

   var [firstGame] = ['Gran Turismo', 'Burnout', 'GTA'];
   
   console.log(firstGame); // Gran Turismo
   

   Using list matching

     var [,secondGame] = ['Gran Turismo', 'Burnout', 'GTA'];
     console.log(secondGame); // Burnout
   

   Using the spread operator

   var [firstGame, ...rest] = ['Gran Turismo', 'Burnout', 'GTA'];
   console.log(firstGame);// Gran Turismo
   console.log(rest);// ['Burnout', 'GTA'];
   

Now that we've got that out of our way, in ES6 you can export multiple modules. You can then make use of object destructuring like below.

Let's assume you have a module called module.js

    export const printFirstname(firstname) => console.log(firstname);
    export const printLastname(lastname) => console.log(lastname);

You would like to import the exported functions into index.js;

    import {printFirstname, printLastname} from './module.js'

    printFirstname('Taylor');
    printLastname('Swift');

You can also use different variable names like so

    import {printFirstname as pFname, printLastname as pLname} from './module.js'

    pFname('Taylor');
    pLanme('Swift');

This one liner resigns Keyboard from all(any) the UITextField in a UIView

self.view.endEditing(true)

Very easily done with Post build task plugin.

Flexbox spec editor here.

This is an encouraged use of flexbox, but there are a few things you should tweak for best behavior.

• Don't use prefixes. Unprefixed flexbox is well-supported across most browsers. Always start with unprefixed, and only add prefixes if necessary to support it.

• Since your header and footer aren't meant to flex, they should both have flex: none; set on them. Right now you have a similar behavior due to some overlapping effects, but you shouldn't rely on that unless you want to accidentally confuse yourself later. (Default is flex:0 1 auto, so they start at their auto height and can shrink but not grow, but they're also overflow:visible by default, which triggers their default min-height:auto to prevent them from shrinking at all. If you ever set an overflow on them, the behavior of min-height:auto changes (switching to zero rather than min-content) and they'll suddenly get squished by the extra-tall <article> element.)

• You can simplify the <article> flex too - just set flex: 1; and you'll be good to go. Try to stick with the common values in https://drafts.csswg.org/css-flexbox/#flex-common unless you have a good reason to do something more complicated - they're easier to read and cover most of the behaviors you'll want to invoke.

If you don't know what property caused the error, you can, using reflection, loop over all properties:

public static String ShowAllErrors<T>(this HtmlHelper helper) {
    StringBuilder sb = new StringBuilder();
    Type myType = typeof(T);
    PropertyInfo[] propInfo = myType.GetProperties();

    foreach (PropertyInfo prop in propInfo) {
        foreach (var e in helper.ViewData.ModelState[prop.Name].Errors) {
            TagBuilder div = new TagBuilder("div");
            div.MergeAttribute("class", "field-validation-error");
            div.SetInnerText(e.ErrorMessage);
            sb.Append(div.ToString());
        }
    }
    return sb.ToString();
}

Where T is the type of your "ViewModel".

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

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

If you are exporting the data from the CSV file it can be as simple as this :

df = pd.read_csv(file_csv, na_values=' ')

This will create the data frame as well as replace blank values as Na

Nc is a link to nmap-ncat.

It would be nice to use nmap-ncat in your puppet, because NC is a virtual name of nmap-ncat.

Puppet cannot understand the links/virtualnames

your puppet should be:

package {
  'nmap-ncat':
    ensure => installed;
}

The assembly coming with Powershell SDK (C:\Program Files\Reference Assemblies\Microsoft\WindowsPowerShell\v1.0) does not come with Powershell 2 specific types.

Manually editing the csproj file solved my problem.

To fix this:

Go to Internet Information Service (IIS)

Click on your website you are trying to load image on

Under IIS section, Open the Authentication menu and Enable Windows Authentication as well.

Add this to your code:

.child { width: 100%; }

We know that a block-level child is supposed to occupy the full width of the parent.

Chrome understands this.

IE11, for whatever reason, wants an explicit request.

Using flex-basis: 100% or flex: 1 also works.

.parent {_x000D_
  display: flex;_x000D_
  flex-direction: column;_x000D_
  width: 400px;_x000D_
  border: 1px solid red;_x000D_
  align-items: center;_x000D_
}_x000D_
.child {_x000D_
  border: 1px solid blue;_x000D_
  width: calc(100% - 2px);       /* NEW; used calc to adjust for parent borders */_x000D_
}

<div class="parent">_x000D_
  <div class="child">_x000D_
    Lorem Ipsum is simply dummy text of the printing and typesetting industry_x000D_
  </div>_x000D_
  <div class="child">_x000D_
    Lorem Ipsum is simply dummy text of the printing and typesetting industry_x000D_
  </div>_x000D_

Note: Sometimes it will be necessary to sort through the various levels of the HTML structure to pinpoint which container gets the width: 100%. CSS wrap text not working in IE

You also need to do manual re-centering if using jquery ui on mobile devices - the dialog is manually positioned via a 'left & top' css property. if the user switches orientation, the positioning is no longer centered, and must be adapted / re-centered afterwards.

If you are only trying to change the include paths for a project and not for all solutions then in Visual Studio 2008 do this: Right-click on the name of the project in the Solution Navigator. From the popup menu select Properties. In the property pages dialog select Configuration Properties->C/C++/General. Click in the text box next to the "Additional Include Files" label and browse for the appropriate directory. Select OK.

What annoys me is that some of the answers to the original question asked do not apply to the version of Visual Studio that was mentioned.

Aside from using %, age of empires III to lower case is age of empires iii so your query should be:

select *
from games
where lower(title) like 'age of empires iii%'

In my case, problem was due to low disk space. I want to mention it for other users like me :)

If you need use it as a default configuration, just place min: 0 inside the node defaults.scale.ticks, as follows:

defaults: {
  global: {...},
  scale: {
    ...
    ticks: { min: 0 },
  }
},

After seeing this for deeply getting attributes, I made the following to safely get nested dict values using dot notation. This works for me because my dicts are deserialized MongoDB objects, so I know the key names don't contain .s. Also, in my context, I can specify a falsy fallback value (None) that I don't have in my data, so I can avoid the try/except pattern when calling the function.

from functools import reduce # Python 3
def deepgetitem(obj, item, fallback=None):
    """Steps through an item chain to get the ultimate value.

    If ultimate value or path to value does not exist, does not raise
    an exception and instead returns `fallback`.

    >>> d = {'snl_final': {'about': {'_icsd': {'icsd_id': 1}}}}
    >>> deepgetitem(d, 'snl_final.about._icsd.icsd_id')
    1
    >>> deepgetitem(d, 'snl_final.about._sandbox.sbx_id')
    >>>
    """
    def getitem(obj, name):
        try:
            return obj[name]
        except (KeyError, TypeError):
            return fallback
    return reduce(getitem, item.split('.'), obj)

There second method will be many times more effective (mostly because of compilers inlining and boxing but still numbers are very expressive):

public static bool CheckObjectImpl(object o)
{
    return o != null;
}

public static bool CheckNullableImpl<T>(T? o) where T: struct
{
    return o.HasValue;
}

So if you have an option (e.g. writing custom serializers) to process Nullable in different pipeline than object - and use their specific properties - do it and use Nullable specific properties. So from consistent thinking point of view HasValue should be preferred. Consistent thinking can help you to write better code do not spending too much time in details.

PS. People say that advice "prefer HasValue because of consistent thinking" is not related and useless. Can you predict the performance of this?

public static bool CheckNullableGenericImpl<T>(T? t) where T: struct
{
    return t != null; // or t.HasValue?
}

PPS People continue minus, seems nobody tries to predict performance of CheckNullableGenericImpl. I will tell you: there compiler will not help you replacing !=null with HasValue. HasValue should be used directly if you are interested in performance.

You're missing an ending anchor.

if(Regex.IsMatch(myString, "^[A-Za-z]{2}[0-9]{2}\z")) {
    // ...
}

Here's a demo.

EDIT: If you can have anything between an initial 2 letters and a final 2 numbers:

if(Regex.IsMatch(myString, @"^[A-Za-z]{2}.*\d{2}\z")) {
    // ...
}

Here's a demo.

This error “Sub or Function not defined”, will come every time when there is some compile error in script, so please check syntax again of your script.

I guess that is why when you used msqbox instead of msgbox it throws the error.

you can use a powerful library for management String which is undrescore.string.js

_('a <a href="#">link</a>').stripTags()

=> 'a link'

_('a <a href="#">link</a><script>alert("hello world!")</script>').stripTags()

=> 'a linkalert("hello world!")'

Don't forget to import this lib as following :

        <script src="underscore.js" type="text/javascript"></script>
        <script src="underscore.string.js" type="text/javascript"></script>
        <script type="text/javascript"> _.mixin(_.str.exports())</script>

Groupby A:

In [0]: grp = df.groupby('A')

Within each group, sum over B and broadcast the values using transform. Then sort by B:

In [1]: grp[['B']].transform(sum).sort('B')
Out[1]:
          B
2 -2.829710
5 -2.829710
1  0.253651
4  0.253651
0  0.551377
3  0.551377

Index the original df by passing the index from above. This will re-order the A values by the aggregate sum of the B values:

In [2]: sort1 = df.ix[grp[['B']].transform(sum).sort('B').index]

In [3]: sort1
Out[3]:
     A         B      C
2  baz -0.528172  False
5  baz -2.301539   True
1  bar -0.611756   True
4  bar  0.865408  False
0  foo  1.624345  False
3  foo -1.072969   True

Finally, sort the 'C' values within groups of 'A' using the sort=False option to preserve the A sort order from step 1:

In [4]: f = lambda x: x.sort('C', ascending=False)

In [5]: sort2 = sort1.groupby('A', sort=False).apply(f)

In [6]: sort2
Out[6]:
         A         B      C
A
baz 5  baz -2.301539   True
    2  baz -0.528172  False
bar 1  bar -0.611756   True
    4  bar  0.865408  False
foo 3  foo -1.072969   True
    0  foo  1.624345  False

Clean up the df index by using reset_index with drop=True:

In [7]: sort2.reset_index(0, drop=True)
Out[7]:
     A         B      C
5  baz -2.301539   True
2  baz -0.528172  False
1  bar -0.611756   True
4  bar  0.865408  False
3  foo -1.072969   True
0  foo  1.624345  False

You can also add (keyup.enter)="xxxx()"

Sorry, brief moment of synapse failure. Here's the real answer.

require 'date'

Time.at(seconds_since_epoch_integer).to_datetime

Brief example (this takes into account the current system timezone):

$ date +%s
1318996912

$ irb

ruby-1.9.2-p180 :001 > require 'date'
 => true 

ruby-1.9.2-p180 :002 > Time.at(1318996912).to_datetime
 => #<DateTime: 2011-10-18T23:01:52-05:00 (13261609807/5400,-5/24,2299161)> 

Further update (for UTC):

ruby-1.9.2-p180 :003 > Time.at(1318996912).utc.to_datetime
 => #<DateTime: 2011-10-19T04:01:52+00:00 (13261609807/5400,0/1,2299161)>

Recent Update: I benchmarked the top solutions in this thread while working on a HA service a week or two ago, and was surprised to find that Time.at(..) outperforms DateTime.strptime(..) (update: added more benchmarks).

To get all the values from a list of dictionaries, use the following code :

list = [{'text': 1, 'b': 2}, {'text': 3, 'd': 4}, {'text': 5, 'f': 6}]
subtitle=[]
for value in list:
   subtitle.append(value['text'])

File file = new File("src/test/resources/validation.txt");
DiskFileItem fileItem = new DiskFileItem("file", "text/plain", false, file.getName(), (int) file.length() , file.getParentFile());
fileItem.getOutputStream();
MultipartFile multipartFile = new CommonsMultipartFile(fileItem);

You need the

fileItem.getOutputStream();

because it will throw NPE otherwise.

A list is a chain of spaces that can be indexed by (0, 1, 2 .... etc). So if players was a list, players[0] or players[1] would have worked. If players is a dictionary, players["name"] would have worked.

Simply :

$(".leaderMultiSelctdropdown").val()

I know this question has been answered but the answers i found here didn't work for my scenario ( or for Windows ).

I am using windows 10 laptop with PHP 7.2 in Xampp v3.2.4.

$command = 'php Cron.php send_email "'. $id .'"';
if ( substr(php_uname(), 0, 7) == "Windows" )
{
    //windows
    pclose(popen("start /B " . $command . " 1> temp/update_log 2>&1 &", "r"));
}
else
{
    //linux
    shell_exec( $command . " > /dev/null 2>&1 &" );
}

This worked perfectly for me.

I hope it will help someone with windows. Cheers.

This can be done by using PsExec which can be downloaded here

psexec \\computer_name -u username -p password ipconfig

If this isn't working try doing this :-

1. Open RegEdit on your remote server.

2. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System.

3. Add a new DWORD value called LocalAccountTokenFilterPolicy

4. Set its value to 1.
5. Reboot your remote server.
6. Try running PSExec again from your local server.

Look at java.lang.BigDecimal, may solve your problem.

http://docs.oracle.com/javase/7/docs/api/java/math/BigDecimal.html

I rewrote the accepted answer and facile it for the newbies.

#break it down and understand it intuitively.
new = {}
for (key, value) in data:
    if key not in new:
        new[key] = [] # this is core of setdefault equals to new.setdefault(key, [])
        new[key].append(value)
    else:
        new[key].append(value)


# easy with setdefault
new = {}
for (key, value) in data:
    group = new.setdefault(key, []) # it is new[key] = []
    group.append(value)



# even simpler with defaultdict
new = defaultdict(list)
for (key, value) in data:
    new[key].append(value) # all keys have a default value of empty list []

Additionally,I categorized the methods as reference:

dict_methods_11 = {
            'views':['keys', 'values', 'items'],
            'add':['update','setdefault'],
            'remove':['pop', 'popitem','clear'],
            'retrieve':['get',],
            'copy':['copy','fromkeys'],}

I suppose that you are using an array to create your select form input. In that case, use an array:

<?php
    $selected = array( $_REQUEST['yesnofine'] => 'selected="selected"' );
    $fields = array(1 => 'Yes', 2 => 'No', 3 => 'Fine');
 ?>
  <select name=‘yesnofine'>
 <?php foreach ($fields as $k => $v): ?>
  <option value="<?php echo $k;?>" <?php @print($selected[$k]);?>><?php echo $v;?></options>
 <?php endforeach; ?>
 </select>

If not, you may just unroll the above loop, and still use an array.

 <option value="1" <?php @print($selected[$k]);?>>Yes</options>
 <option value="2" <?php @print($selected[$k]);?>>No</options>
 <option value="3" <?php @print($selected[$k]);?>>Fine</options>

Notes that I don't know:

• how you are naming your input, so I made up a name for it.
• which way you are handling your form input on server side, I used $_REQUEST,

You will have to adapt the code to match requirements of the framework you are using, if any.

Also, it is customary in many frameworks to use the alternative syntax in view dedicated scripts.

You could stil use @TEMP if you quote the identifier "@TEMP":

declare @TEMP table (ID int, Name varchar(max));
insert into @temp SELECT 1 AS ID, 'a' Name;

SELECT * FROM @TEMP WHERE "@TEMP".ID  = 1 ;   

db<>fiddle demo

If your input rows are lists rather than dictionaries, then the following is a simple solution:

import pandas as pd
list_of_lists = []
list_of_lists.append([1,2,3])
list_of_lists.append([4,5,6])

pd.DataFrame(list_of_lists, columns=['A', 'B', 'C'])
#    A  B  C
# 0  1  2  3
# 1  4  5  6

Well, I faced the same issue. For new users who may land at this page. Just follow their official documentation.

Install flask-cors

pip install -U flask-cors

then after app initialization, initialize flask-cors with default arguments:

from flask import Flask
from flask_cors import CORS

app = Flask(__name__)
CORS(app)

@app.route("/")
def helloWorld():
   return "Hello, cross-origin-world!"

Have that issue. So long time pass... Without side-fields of page it's break normal, but when fields appears, page and "page break space" will scale. So, with a normal field, within a document, it was shown incorrect. I fix it with set

    width:100%

and use

div.page
  {
    page-break-before: always;
    page-break-inside: avoid;
  }

Use it on first line.

changing the width of the image will automatically change the height...

how many pictures do you want to have this functionality? If it's a lot and they all have DIFFERENT Heights you should probably just let the height change as well.

Lets say you have 5 images that have height 400px , in your html give those five tags the class of fixed

.fixed { width: 100%; height: 500px !important }

This should let the width change but keep the height the same.

You need to use the openssl pkcs12 -export -chain -in server.crt -CAfile ...

You can use RoundingMode.#UNNECESSARY if you want/accept exception thrown otherwise

new BigDecimal(value).setScale(2, RoundingMode.UNNECESSARY);

If this rounding mode is specified on an operation that yields an inexact result, an ArithmeticException is thrown.

Exception if not integer value:

java.lang.ArithmeticException: Rounding necessary

No you don't need to check if you're in the main thread. Here is how you can do this in Swift:

runThisInMainThread { () -> Void in
    runThisInMainThread { () -> Void in
        // No problem
    }
}

func runThisInMainThread(block: dispatch_block_t) {
    dispatch_async(dispatch_get_main_queue(), block)
}

Its included as a standard function in my repo, check it out: https://github.com/goktugyil/EZSwiftExtensions

Primary key - we can put only one primary key on a table into a table and we can not left that column blank when we are entering the values into the table.

Unique Key - we can put more than one unique key on a table and we may left that column blank when we are entering the values into the table. column take unique values (not same) when we applied primary & unique key.

You are right, it's confusing that SQL Server allows you to create duplicate indexes on the same field(s). But the fact that you can create another doesn't indicate that the PK index doesn't also already exist.

The additional index does no good, but the only harm (very small) is the additional file size and row-creation overhead.

it might be nice toggling in one line of code:

let video = $('video')[0];_x000D_
video[video.paused ? 'play' : 'pause']();

import re
pattern = re.compile("<(\d{4,5})>")

for i, line in enumerate(open('test.txt')):
    for match in re.finditer(pattern, line):
        print 'Found on line %s: %s' % (i+1, match.group())

A couple of notes about the regex:

• You don't need the ? at the end and the outer (...) if you don't want to match the number with the angle brackets, but only want the number itself
• It matches either 4 or 5 digits between the angle brackets

Update: It's important to understand that the match and capture in a regex can be quite different. The regex in my snippet above matches the pattern with angle brackets, but I ask to capture only the internal number, without the angle brackets.

More about regex in python can be found here : Regular Expression HOWTO

I know there are a lot of answers, but another solution could be to go with decorators. This is an example to repeat a function everyday at a specific time. The cool think about using this way is that you only need to add the Syntactic Sugar to the function you want to schedule:

@repeatEveryDay(hour=6, minutes=30)
def sayHello(name):
    print(f"Hello {name}")

sayHello("Bob") # Now this function will be invoked every day at 6.30 a.m

And the decorator will look like:

def repeatEveryDay(hour, minutes=0, seconds=0):
    """
    Decorator that will run the decorated function everyday at that hour, minutes and seconds.
    :param hour: 0-24
    :param minutes: 0-60 (Optional)
    :param seconds: 0-60 (Optional)
    """
    def decoratorRepeat(func):

        @functools.wraps(func)
        def wrapperRepeat(*args, **kwargs):

            def getLocalTime():
                return datetime.datetime.fromtimestamp(time.mktime(time.localtime()))

            # Get the datetime of the first function call
            td = datetime.timedelta(seconds=15)
            if wrapperRepeat.nextSent == None:
                now = getLocalTime()
                wrapperRepeat.nextSent = datetime.datetime(now.year, now.month, now.day, hour, minutes, seconds)
                if wrapperRepeat.nextSent < now:
                    wrapperRepeat.nextSent += td

            # Waiting till next day
            while getLocalTime() < wrapperRepeat.nextSent:
                time.sleep(1)

            # Call the function
            func(*args, **kwargs)

            # Get the datetime of the next function call
            wrapperRepeat.nextSent += td
            wrapperRepeat(*args, **kwargs)

        wrapperRepeat.nextSent = None
        return wrapperRepeat

In CSS you need to use a Unicode escape sequence in place of HTML Entities. This is based on the hexadecimal value of a character.

I found that the easiest way to convert symbol to their hexadecimal equivalent is, such as from ▾ (▾) to \25BE is to use the Microsoft calculator =)

Yes. Enable programmers mode, turn on the decimal system, enter 9662, then switch to hex and you'll get 25BE. Then just add a backslash \ to the beginning.

One of the way is Using below sql queries

--Size of All Table Space

--1. Used Space

you have to include two more jar files.

xmlbeans-2.3.0.jar and dom4j-1.6.1.jar Add try it will work.

Note: It is required for the files with .xlsx formats only, not for just .xlt formats.

Explicit...

cursor foo is select * from blah; begin open fetch exit when close cursor yada yada yada

don't use them, use implicit

cursor foo is select * from blah;

for n in foo loop x = n.some_column end loop

I think you can even do this

for n in (select * from blah) loop...

Stick to implicit, they close themselves, they are more readable, they make life easy.

Comparisons are case insensitive when the column uses a collation which ends with _ci (such as the default latin1_general_ci collation) and they are case sensitive when the column uses a collation which ends with _cs or _bin (such as the utf8_unicode_cs and utf8_bin collations).

Check collation

You can check your server, database and connection collations using:

mysql> show variables like '%collation%';
+----------------------+-------------------+
| Variable_name        | Value             |
+----------------------+-------------------+
| collation_connection | utf8_general_ci   |
| collation_database   | latin1_swedish_ci |
| collation_server     | latin1_swedish_ci |
+----------------------+-------------------+

and you can check your table collation using:

mysql> SELECT table_schema, table_name, table_collation 
       FROM information_schema.tables WHERE table_name = `mytable`;
+----------------------+------------+-------------------+
| table_schema         | table_name | table_collation   |
+----------------------+------------+-------------------+
| myschema             | mytable    | latin1_swedish_ci |

Change collation

You can change your database, table, or column collation to something case sensitive as follows:

-- Change database collation
ALTER DATABASE `databasename` DEFAULT CHARACTER SET utf8 COLLATE utf8_bin;

-- or change table collation
ALTER TABLE `table` CONVERT TO CHARACTER SET utf8 COLLATE utf8_bin;

-- or change column collation
ALTER TABLE `table` CHANGE `Value` 
    `Value` VARCHAR(255) CHARACTER SET utf8 COLLATE utf8_bin;

Your comparisons should now be case-sensitive.

Many of the answers discuss how many UUIDs would have to be generated to reach a 50% chance of a collision. But a 50%, 25%, or even 1% chance of collision is worthless for an application where collision must be (virtually) impossible.

Do programmers routinely dismiss as "impossible" other events that can and do occur?

When we write data to a disk or memory and read it back again, we take for granted that the data are correct. We rely on the device's error correction to detect any corruption. But the chance of undetected errors is actually around 2^-50.

Wouldn't it make sense to apply a similar standard to random UUIDs? If you do, you will find that an "impossible" collision is possible in a collection of around 100 billion random UUIDs (2^36.5).

This is an astronomical number, but applications like itemized billing in a national healthcare system, or logging high frequency sensor data on a large array of devices could definitely bump into these limits. If you are writing the next Hitchhiker's Guide to the Galaxy, don't try to assign UUIDs to each article!

public static void main (String[] args) {

     System.out.println("Simple Java Word Count Program");

     String str1 = "Today is Holdiay Day";

     String[] wordArray = str1.trim().split("\\s+");
     int wordCount = wordArray.length;

     System.out.println("Word count is = " + wordCount);
}

The ideas is to split the string into words on any whitespace character occurring any number of times. The split function of the String class returns an array containing the words as its elements. Printing the length of the array would yield the number of words in the string.

Sets toast to a specific period in milli-seconds:

public void toast(int millisec, String msg) {
    Handler handler = null;
    final Toast[] toasts = new Toast[1];
    for(int i = 0; i < millisec; i+=2000) {
        toasts[0] = Toast.makeText(this, msg, Toast.LENGTH_SHORT);
        toasts[0].show();
        if(handler == null) {
            handler = new Handler();
            handler.postDelayed(new Runnable() {
                @Override
                public void run() {
                    toasts[0].cancel();
                }
            }, millisec);
        }
    }
}

From the man page:

-h, --no-filename
    Suppress the prefixing of file names on output. This is the default when there
    is only one file (or only standard input) to search.

I fixed this by running a clean of by gradle build (or delete the gradle build folder mannually)

This occurs if you move the main class to a new package and the old main class is still referenced in the claspath

Here you will find a better solution OLTP vs. OLAP

• OLTP (On-line Transaction Processing) is involved in the operation of a particular system. OLTP is characterized by a large number of short on-line transactions (INSERT, UPDATE, DELETE). The main emphasis for OLTP systems is put on very fast query processing, maintaining data integrity in multi-access environments and an effectiveness measured by number of transactions per second. In OLTP database there is detailed and current data, and schema used to store transactional databases is the entity model (usually 3NF). It involves Queries accessing individual record like Update your Email in Company database.

• OLAP (On-line Analytical Processing) deals with Historical Data or Archival Data. OLAP is characterized by relatively low volume of transactions. Queries are often very complex and involve aggregations. For OLAP systems a response time is an effectiveness measure. OLAP applications are widely used by Data Mining techniques. In OLAP database there is aggregated, historical data, stored in multi-dimensional schemas (usually star schema). Sometime query need to access large amount of data in Management records like what was the profit of your company in last year.

Nothing I've seen anywhere indicates you can ad-hoc deploy to a real iPhone without a (paid for) certificate.

You should use raw_input to take a string input. then use islower method of str object.

s = raw_input('Type a word')
l = []
for c in s.strip():
    if c.islower():
        print c
        l.append(c)
print 'Total number of lowercase letters: %d'%(len(l) + 1)

Just do -

dir(s)

and you will find islower and other attributes of str

The two errors you have in your code are very different.

The first problem is that you're initializing and populating your Map in the body of the class without a statement. You can either have a static Map and a static {//TODO manipulate Map} statement in the body of the class, or initialize and populate the Map in a method or in the class' constructor.

The second problem is that you cannot treat a Map syntactically like an array, so the statement data["John"] = "Taxi Driver"; should be replaced by data.put("John", "Taxi Driver"). If you already have a "John" key in your HashMap, its value will be replaced with "Taxi Driver".

If you want to have cd functionality (assuming shell=True) and still want to change the directory in terms of the Python script, this code will allow 'cd' commands to work.

import subprocess
import os

def cd(cmd):
    #cmd is expected to be something like "cd [place]"
    cmd = cmd + " && pwd" # add the pwd command to run after, this will get our directory after running cd
    p = subprocess.Popen(cmd, shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE, universal_newlines=True) # run our new command
    out = p.stdout.read()
    err = p.stderr.read()
    # read our output
    if out != "":
        print(out)
        os.chdir(out[0:len(out) - 1]) # if we did get a directory, go to there while ignoring the newline 
    if err != "":
        print(err) # if that directory doesn't exist, bash/sh/whatever env will complain for us, so we can just use that
    return

The fact that the first digit has to be in the range 5-9 only applies in case of two digits. So, check for that in the case of 2 digits, and allow any more digits directly:

^([5-9]\d|\d{3,})$

This regexp has beginning/ending anchors to make sure you're checking all digits, and the string actually represents a number. The | means "or", so either [5-9]\d or any number with 3 or more digits. \d is simply a shortcut for [0-9].

Edit: To disallow numbers like 001:

^([5-9]\d|[1-9]\d{2,})$

This forces the first digit to be not a zero in the case of 3 or more digits.

After opening local bootstrap.min.css in visual studio code, it looked unindented. Tried the commad ALT+Shift+F but in vain.

Then installed

Reloaded it and ALT+Shift+F indented my CSS file with charm.

Bingo !!!

Try this:

-1 * numeric_limits<double>::max()

Reference: numeric_limits

This class is specialized for each of the fundamental types, with its members returning or set to the different values that define the properties that type has in the specific platform in which it compiles.

@codeling and @user1767754 : The following two lines will work. I saw no one posted the complete solution for the example problem that was asked. Hopefully this is enough explanation.

import datetime

x = datetime.datetime.strptime("Mon Feb 15 2010", "%a %b %d %Y").strftime("%d/%m/%Y")
print(x)

Output:

15/02/2010

When you define you own html form then you have to include authentication token string ,that should be sent to controller for security reasons. If you use rails form helper to generate the authenticity token is added to form as follow.

<form accept-charset="UTF-8" action="/login/signin" method="post">
  <div style="display:none">
    <input name="utf8" type="hidden" value="&#x2713;" />
    <input name="authenticity_token" type="hidden" value="x37DrAAwyIIb7s+w2+AdoCR8cAJIpQhIetKRrPgG5VA=">
  </div>
    ...
</form>

So the solution to the problem is either to add authenticity_token field or use rails form helpers rather then compromising security etc.

As the documentation clearly states, Character.getNumericValue() returns the character's value as a digit.
It returns -1 if the character is not a digit.

If you want to get the numeric Unicode code point of a boxed Character object, you'll need to unbox it first:

int value = (int)c.charValue();

Option 1 : The traditional for-loop

The basics

A traditional for-loop has three components :

1. the initialization : executed before the look block is executed the first time
2. the condition : checks a condition every time before the loop block is executed, and quits the loop if false
3. the afterthought : performed every time after the loop block is executed

These three components are seperated from each other by a ; symbol. Content for each of these three components is optional, which means that the following is the most minimal for-loop possible :

for (;;) {
    // Do stuff
}

Of course, you will need to include an if(condition === true) { break; } or an if(condition === true) { return; } somewhere inside that for-loop to get it to stop running.

Usually, though, the initialization is used to declare an index, the condition is used to compare that index with a minimum or maximum value, and the afterthought is used to increment the index :

for (var i = 0, length = 10; i < length; i++) {
    console.log(i);
}

Using a tradtional for-loop to loop through an array

The traditional way to loop through an array, is this :

for (var i = 0, length = myArray.length; i < length; i++) {
    console.log(myArray[i]);
}

Or, if you prefer to loop backwards, you do this :

for (var i = myArray.length - 1; i > -1; i--) {
    console.log(myArray[i]);
}

There are, however, many variations possible, like eg. this one :

for (var key = 0, value = myArray[key], var length = myArray.length; key < length; value = myArray[++key]) {
    console.log(value);
}

... or this one ...

var i = 0, length = myArray.length;
for (; i < length;) {
    console.log(myArray[i]);
    i++;
}

... or this one :

var key = 0, value;
for (; value = myArray[key++];){ 
    console.log(value);
}

Whichever works best is largely a matter of both personal taste and the specific use case you're implementing.

Each of these variations is supported by all browsers, including véry old ones!

Option 2 : The while-loop

One alternative to a for-loop is a while-loop. To loop through an array, you could do this :

var key = 0;
while(value = myArray[key++]){
    console.log(value);
}

Like traditional for-loops, while-loops are supported by even the oldest of browsers.

Also, every while loop can be rewritten as a for-loop. For example, the while-loop hereabove behaves the exact same way as this for-loop :

for(var key = 0;value = myArray[key++];){
    console.log(value);
}

Option 3 : for...in and for...of

In JavaScript, you can also do this :

for (i in myArray) {
    console.log(myArray[i]);
}

This should be used with care, however, as it doesn't behave the same as a traditonal for-loop in all cases, and there are potential side-effects that need to be considered. See Why is using "for...in" with array iteration a bad idea? for more details.

As an alternative to for...in, there's now also for for...of. The following example shows the difference between a for...of loop and a for...in loop :

var myArray = [3, 5, 7];
myArray.foo = "hello";

for (var i in myArray) {
  console.log(i); // logs 0, 1, 2, "foo"
}

for (var i of myArray) {
  console.log(i); // logs 3, 5, 7
}

You also need to consider that no version of Internet Explorer supports for...of (Edge 12+ does) and that for...in requires at least IE10.

Option 4 : Array.prototype.forEach()

An alternative to For-loops is Array.prototype.forEach(), which uses the following syntax :

myArray.forEach(function(value, key, myArray) {
    console.log(value);
});

Array.prototype.forEach() is supported by all modern browsers, as well as IE9+.

Option 5 : jQuery.each()

Additionally to the four other options mentioned, jQuery also had its own foreach variation.

It uses the following syntax :

$.each(myArray, function(key, value) {
    console.log(value);
});

Run in command prompt.

pip list

Check what version you have installed on your system if you have an old version.

Try to uninstall the package...

pip uninstall requests

Try after to install it:

pip install requests

You can also test if pip does not do the job.

easy_install requests

If you want to get the date when the user selects it, you can do this:

$("#datepicker").datepicker({
    onSelect: function() { 
        var dateObject = $(this).datepicker('getDate'); 
    }
});

I am not sure about the second part of your question. But, have you tried using style sheets and relative positioning?

The warning from your compiler is telling you that your format specifier doesn't match the data type you're passing to it.

Try using %lx or %llx. For more portability, include inttypes.h and use the PRIx64 macro.

For example: printf("val = 0x%" PRIx64 "\n", val); (note that it's string concatenation)

If you have two []byte, compare them using bytes.Equal. The Golang documentation says:

Equal returns a boolean reporting whether a and b are the same length and contain the same bytes. A nil argument is equivalent to an empty slice.

Usage:

package main

import (
    "fmt"
    "bytes"
)

func main() {
    a := []byte {1,2,3}
    b := []byte {1,2,3}
    c := []byte {1,2,2}

    fmt.Println(bytes.Equal(a, b))
    fmt.Println(bytes.Equal(a, c))
}

This will print

true
false

You can't change the color of the line (you can't specify different foreground colors for the same element, and the text and its decoration form a single element). However there are some tricks:

a:link, a:visited {text-decoration: none; color: red; border-bottom: 1px solid #006699; }
a:hover, a:active {text-decoration: none; color: red; border-bottom: 1px solid #1177FF; }

Also you can make some cool effects this way:

a:link {text-decoration: none; color: red; border-bottom: 1px dashed #006699; }

Hope it helps.

If you're at the top level - or able to cleanly get to the top level - of the thread, then just returning is nice. Throwing an exception isn't as clean, as you need to be able to check that nothing's going to catch the exception and ignore it.

The reason you need to use Thread.currentThread() in order to call interrupt() is that interrupt() is an instance method - you need to call it on the thread you want to interrupt, which in your case happens to be the current thread. Note that the interruption will only be noticed the next time the thread would block (e.g. for IO or for a monitor) anyway - it doesn't mean the exception is thrown immediately.

Context

• YAML version 1.2
• user wishes to
  • include variable placeholders in YAML
  • have placeholders replaced with computed values, upon yaml.load
  • be able to use placeholders for both YAML mapping keys and values

Problem

• YAML does not natively support variable placeholders.
• Anchors and Aliases almost provide the desired functionality, but these do not work as variable placeholders that can be inserted into arbitrary regions throughout the YAML text. They must be placed as separate YAML nodes.
• There are some add-on libraries that support arbitrary variable placeholders, but they are not part of the native YAML specification.

Example

Consider the following example YAML. It is well-formed YAML syntax, however it uses (non-standard) curly-brace placeholders with embedded expressions.

The embedded expressions do not produce the desired result in YAML, because they are not part of the native YAML specification. Nevertheless, they are used in this example only to help illustrate what is available with standard YAML and what is not.

Explanation

• The substitutions marked in GREEN are readily available in standard YAML, using anchors, aliases, and merge keys.

• The substitutions marked in YELLOW are technically available in standard YAML, but not without a custom type declaration, or some other binding mechanism.

• The substitutions marked in RED are not available in standard YAML. Yet there are workarounds and alternatives; such as through string formatting or string template engines (such as python's str.format).

Details

A frequently-requested feature for YAML is the ability to insert arbitrary variable placeholders that support arbitrary cross-references and expressions that relate to the other content in the same (or transcluded) YAML file(s).

YAML supports anchors and aliases, but this feature does not support arbitrary placement of placeholders and expressions anywhere in the YAML text. They only work with YAML nodes.

YAML also supports custom type declarations, however these are less common, and there are security implications if you accept YAML content from potentially untrusted sources.

YAML addon libraries

There are YAML extension libraries, but these are not part of the native YAML spec.

• Ansible
  • https://docs.ansible.com/ansible-container/container_yml/template.html
  • (supports many extensions to YAML, however it is an Orchestration tool, which is overkill if you just want YAML)
• https://github.com/kblomqvist/yasha
• https://bitbucket.org/djarvis/yamlp

Workarounds

• Use YAML in conjunction with a template system, such as Jinja2 or Twig
• Use a YAML extension library
• Use sprintf or str.format style functionality from the hosting language

Alternatives

• YTT YAML Templating essentially a fork of YAML with additional features that may be closer to the goal specified in the OP.
• Jsonnet shares some similarity with YAML, but with additional features that may be closer to the goal specified in the OP.

(ps: the answer given by Nick Craver is incorrect)

contentType specifies the format of data being sent to the server as part of request(it can be sent as part of response too, more on that later).

dataType specifies the expected format of data to be received by the client(browser).

Both are not interchangable.

• contentType is the header sent to the server, specifying the format of data(i.e the content of message body) being being to the server. This is used with POST and PUT requests. Usually when u send POST request, the message body comprises of passed in parameters like:

==============================

Sample request:

POST /search HTTP/1.1 
Content-Type: application/x-www-form-urlencoded 
<<other header>>

name=sam&age=35

==============================

The last line above "name=sam&age=35" is the message body and contentType specifies it as application/x-www-form-urlencoded since we are passing the form parameters in the message body. However we aren't limited to just sending the parameters, we can send json, xml,... like this(sending different types of data is especially useful with RESTful web services):

==============================

Sample request:

POST /orders HTTP/1.1
Content-Type: application/xml
<<other header>>

<order>
   <total>$199.02</total>
   <date>December 22, 2008 06:56</date>
...
</order>

==============================

So the ContentType this time is: application/xml, cause that's what we are sending. The above examples showed sample request, similarly the response send from the server can also have the Content-Type header specifying what the server is sending like this:

==============================

sample response:

HTTP/1.1 201 Created
Content-Type: application/xml
<<other headers>>

<order id="233">
   <link rel="self" href="http://example.com/orders/133"/>
   <total>$199.02</total>
   <date>December 22, 2008 06:56</date>
...
</order>

==============================

• dataType specifies the format of response to expect. Its related to Accept header. JQuery will try to infer it based on the Content-Type of the response.

==============================

Sample request:

GET /someFolder/index.html HTTP/1.1
Host: mysite.org
Accept: application/xml
<<other headers>>

==============================

Above request is expecting XML from the server.

Regarding your question,

contentType: "application/json; charset=utf-8",
dataType: "json",

Here you are sending json data using UTF8 character set, and you expect back json data from the server. As per the JQuery docs for dataType,

The json type parses the fetched data file as a JavaScript object and returns the constructed object as the result data.

So what you get in success handler is proper javascript object(JQuery converts the json object for you)

whereas

contentType: "application/json",
dataType: "text",

Here you are sending json data, since you haven't mentioned the encoding, as per the JQuery docs,

If no charset is specified, data will be transmitted to the server using the server's default charset; you must decode this appropriately on the server side.

and since dataType is specified as text, what you get in success handler is plain text, as per the docs for dataType,

The text and xml types return the data with no processing. The data is simply passed on to the success handler

ALTER IGNORE TABLE test
           ADD UNIQUE INDEX 'test' ('b'); 

@ here 'b' is column name to uniqueness, @ here 'test' is index name.

An Alternative Solution to the above

Card(
  shape: RoundedRectangleBorder(
     borderRadius: BorderRadius.only(topLeft: Radius.circular(20), topRight: Radius.circular(20))),
  color: Colors.white,
  child: ...
)

You can use BorderRadius.only() to customize the corners you wish to manage.

For my console program the answers with tkinter above did not quite work for me because the .destroy() always gave an error,:

can't invoke "event" command: application has been destroyed while executing...

or when using .withdraw() the console window did not get the focus back.

To solve this you also have to call .update() before the .destroy(). Example:

# Python 3
import tkinter

r = tkinter.Tk()
text = r.clipboard_get()
r.withdraw()
r.update()
r.destroy()

The r.withdraw() prevents the frame from showing for a milisecond, and then it will be destroyed giving the focus back to the console.

The SettingWithCopyWarning was created to flag potentially confusing "chained" assignments, such as the following, which does not always work as expected, particularly when the first selection returns a copy. [see GH5390 and GH5597 for background discussion.]

df[df['A'] > 2]['B'] = new_val  # new_val not set in df

The warning offers a suggestion to rewrite as follows:

df.loc[df['A'] > 2, 'B'] = new_val

However, this doesn't fit your usage, which is equivalent to:

df = df[df['A'] > 2]
df['B'] = new_val

While it's clear that you don't care about writes making it back to the original frame (since you are overwriting the reference to it), unfortunately this pattern cannot be differentiated from the first chained assignment example. Hence the (false positive) warning. The potential for false positives is addressed in the docs on indexing, if you'd like to read further. You can safely disable this new warning with the following assignment.

import pandas as pd
pd.options.mode.chained_assignment = None  # default='warn'

As the message says:

no changes added to commit (use "git add" and/or "git commit -a")

Git has a "staging area" where files need to be added before being committed, you can read an explanation of it here.

For your specific example, you can use:

git commit -am "save arezzo files"

(note the extra a in the flags, can also be written as git commit -a -m "message" - both do the same thing)

Alternatively, if you want to be more selective about what you add to the commit, you use the git add command to add the appropriate files to the staging area, and git status to preview what is about to be added (remembering to pay attention to the wording used).

You can also find general documentation and tutorials for how to use git on the git documentation page which will give more detail about the concept of staging/adding files.

One other thing worth knowing about is interactive staging - this allows you to add parts of a file to the staging area, so if you've made three distinct code changes (for related but different functionality), you can use interactive mode to split the changes and add/commit each part in turn. Having smaller specific commits like this can be helpful.

Normally you'd just stick the code in Page_Load in your .aspx page's code-behind.

if (someVar) {
    Item1.Visible = true;
    Item2.Visible = false;
} else {
    Item1.Visible = false;
    Item2.Visible = true;
}

This assumes you've got Item1 and Item2 laid out on the page already.
